PRELIMINARY—SUBJECT TO COMPLETION, DATED MARCH 14, 2022

BUSINESS COMBINATIONS PROPOSED—YOUR VOTE IS VERY IMPORTANT

[●], 2022

On December 22, 2021, Quidel Corporation (“Quidel”) and Ortho Clinical Diagnostics Holdings plc (“Ortho”) entered into a Business Combination Agreement (the “BCA”) by and among Quidel, Ortho, Coronado Topco, Inc. (“Topco”), Orca Holdco, Inc. (“U.S. Holdco Sub”) and Laguna Merger Sub, Inc. (“U.S. Merger Sub”), each wholly owned subsidiaries of Topco, and Orca Holdco 2, Inc., a wholly owned subsidiary of U.S. Holdco Sub (“U.S. Holdco Sub 2”), which provides for the acquisition of Ortho and Quidel by Topco. The combined company will unite world-class technologies and platforms to benefit customers with expanded access to clinical chemistry, immunoassay, molecular diagnostics, immunohematology, donor screening and point-of-care diagnostics offerings. We are extremely pleased about this transaction and look forward to the opportunities it presents. We are sending you this joint proxy statement/prospectus to ask you to vote in favor of these transactions and other related matters.

Pursuant to the BCA, the “Combinations” are expected to be implemented by means of (i) a scheme of arrangement to be undertaken by Ortho under Part 26 of the UK Companies Act (the “Ortho Scheme”), pursuant to which the Scheme Shares (as defined in the Scheme of Arrangement (hereinafter mentioned)) will be acquired by a nominee of Topco (or, if such nominee holds the Ortho Shares today, transferred within the nominee), such that Ortho will become a wholly owned subsidiary of Topco and (ii) a merger (the “Quidel Merger”) of U.S. Merger Sub with and into Quidel immediately following consummation of the Ortho Scheme, with Quidel surviving the merger as a wholly owned subsidiary of Topco. At the effective time of the Ortho Scheme, each Ortho Share, other than Ortho Shares held by Ortho in treasury, will be acquired by a nominee (or, if such nominee holds the Ortho Shares today, transferred within the nominee) on behalf and for the benefit of Topco in exchange for 0.1055 shares of common stock of Topco (the “Topco Shares”) and $7.14 in cash. At the effective time of the Quidel Merger, each share of common stock of Quidel (each, a “Quidel Share”), other than Quidel Shares held by Quidel, Ortho or U.S. Merger Sub, will be converted into the right to receive one Topco Share. The number of Topco Shares that Quidel stockholders will receive in the Quidel Merger and that Ortho shareholders will receive in the Ortho Scheme is based on a fixed exchange ratio that will not be adjusted to reflect changes in the market value of Quidel Shares or Ortho Shares. The parties intend to list the Topco Shares to be issued in the Combinations on the Nasdaq Global Select Market (“Nasdaq”).

Under the terms of the BCA, which was unanimously approved by the board of directors of each of Quidel and Ortho, Quidel and Ortho are entering into a business combination under Topco, a new holding company, in which Ortho will be acquired for the per-share consideration described above, including $1.75 billion of cash in the aggregate, funded through cash on the Quidel balance sheet and expected incremental borrowings. Following the closing of the Combinations, Ortho’s current net debt of $2.0 billion is expected to continue to be outstanding. If the Combinations are completed, Ortho shareholders are expected to own approximately 38% of Topco and Quidel stockholders are expected to own approximately 62% of Topco on a fully diluted basis, based on the respective capitalizations of Ortho and Quidel as of the date the parties entered into the BCA.

This document, which forms part of a registration statement on Form S-4 filed with the U.S. Securities and Exchange Commission (the “SEC”) by Topco, is a joint proxy statement/prospectus for Quidel and Ortho to solicit proxies for (i) the Quidel stockholders’ meeting to approve and adopt the BCA and the Quidel Merger and (ii) the Ortho shareholder meetings to approve the Ortho Scheme, amend the articles of association of Ortho and authorize the directors of Ortho to take all such action as they may consider necessary or appropriate for carrying the Ortho Scheme into effect. The registration statement includes the scheme circular with respect to the Ortho Scheme (as required by the UK Companies Act) and registers the Topco Shares to be issued in the Combinations.

Your vote is very important. We cannot complete these transactions unless the Quidel stockholders vote to approve the BCA, the Quidel Merger and certain matters related thereto, and the Ortho shareholders vote to approve the Ortho Scheme and certain matters related thereto. The Ortho Scheme also requires the sanction of the High Court of Justice of England and Wales (the “Court”). IT IS IMPORTANT THAT AS MANY ORTHO SHAREHOLDERS AS POSSIBLE VOTE AND/OR PROVIDE VOTING INSTRUCTIONS ON THE ORTHO SCHEME SO THAT THE COURT MAY BE SATISFIED THAT THERE IS A FAIR AND REASONABLE REPRESENTATION OF THE OPINION OF HOLDERS OF INTERESTS IN ORTHO SHARES.

Please carefully read this entire document, including the section entitled “Risk Factors” for a discussion of the risks relating to the Combinations and Topco following the Combinations. None of the SEC, any state securities regulatory authority or the UK Financial Conduct Authority (the “FCA”) has approved or disapproved of the Combinations or the securities to be issued in the Combinations or has passed upon the adequacy or accuracy of the disclosure in this joint proxy statement/prospectus. Any representation to the contrary is a criminal offense.

For the avoidance of doubt, this joint proxy statement/prospectus is not intended to be, and is not, a prospectus for the purposes of the Prospectus Rules made under Part 6 of the UK Financial Services and Markets Act 2000 (as set out in the FCA’s Handbook).

The accompanying joint proxy statement/prospectus is dated [●], 2022, and is first being mailed to Quidel stockholders and Ortho shareholders on or about [●], 2022.

The poll shall remain open for a period of thirty minutes following the discussion of the matters to be determined at the Ortho Court Meeting to enable Scheme Shareholders to amend their vote, if they so wish.

Right to Appoint a Proxy; Procedure for Appointment

Scheme Shareholders are strongly encouraged to submit proxy appointments and instructions for the Ortho Court Meeting as soon as possible, using any of the methods (by hand, post or online) set out in the below Notes to this notice. Scheme Shareholders are also strongly encouraged to appoint the Chair of the Ortho Court Meeting as their proxy.

Instructions for accessing the Virtual Meeting Platform and information on how to appoint a proxy are set out in the below Notes to this notice.

Voting Record Time

Entitlement to attend (remotely, via the Virtual Meeting Platform) and vote (remotely, via the Virtual Meeting Platform, or by proxy) at the Ortho Court Meeting or any adjournment thereof and the number of votes which may be cast at the Ortho Court Meeting will be determined by reference to the register of members of Ortho at the “Voting Record Time,” which is [●] [a.m./ p.m.] (Eastern Standard Time) and [6:00] p.m. (London time) on [●], 2022 the date that is two Business Days (as defined herein) prior to the Ortho Court Meeting, or, if the Ortho Court Meeting is adjourned, [●] [a.m./ p.m.] (Eastern Standard Time) and [6:00] p.m. (London time) on the date which is two Business Days before the date fixed for the adjourned meeting.

As an alternative to appointing a proxy, any holder of Scheme Shares which is a corporation may appoint one or more corporate representatives who may exercise on its behalf all its powers as a member, provided that if two or more corporate representatives purport to vote in respect of the same shares, if they purport to exercise the power in the same way as each other, the power is treated as exercised in that way, and in other cases the power is treated as not exercised.

By the said order, the Court has appointed Christopher Smith, or failing him, any other Ortho director to act as Chair of the Ortho Court Meeting and has directed the Chair to report the result thereof to the Court. The Scheme of Arrangement will be subject to the subsequent sanction of the Court.

3. | RIGHT TO APPOINT A PROXY; PROCEDURE FOR APPOINTMENT

Scheme Shareholders are strongly encouraged to submit proxy appointments and instructions for the Ortho Court Meeting as soon as possible, using any of the methods (by hand, post or online) set out below. Scheme Shareholders are also strongly encouraged to appoint the Chair of the Ortho Court Meeting as their proxy. If any other person is appointed as proxy, he or she will not be permitted to attend the Ortho Court Meeting in person, but will be able to attend, submit written questions and vote at the Ortho Court Meeting remotely via the Virtual Meeting Platform as described above.

The completion and return of the blue form of proxy by post (or appointment of a proxy online) will not prevent you from remotely attending, submitting questions and voting at the Ortho Court Meeting, in each case via the Virtual Meeting Platform, if you are entitled to and wish to do so.

Scheme Shareholders are entitled to attend and vote at the Ortho Court Meeting and may appoint one or more proxies to exercise all or any of such Scheme Shareholder’s rights to attend, submit written questions and, on a poll, to vote (in each case, remotely, via the Virtual Meeting Platform), on their behalf. A proxy need not be a Scheme Shareholder but must attend the meeting for the Scheme Shareholder’s vote to be counted. If a Scheme Shareholder appoints more than one proxy to attend the meeting, each proxy must be appointed to exercise the rights attached to a different share or shares held by the Scheme Shareholder. If a Scheme Shareholder wishes to appoint more than one proxy, they should contact [Computershare], Ortho’s registrar, for further blue forms of proxy or photocopy the blue form of proxy as required.

Scheme Shareholders who do not appoint a proxy will still be entitled to remotely attend, submit written questions and vote at the Ortho Court Meeting via the Virtual Meeting Platform.

The Chair shall seek the consent of the Court to be at liberty to accept forms of proxy (and to accept as having voted the number of Scheme Shares in respect of which the relevant Scheme Shareholder seeks to vote) notwithstanding that the form of proxy has not been completed in accordance with the instructions contained in the forms of proxy, provided the Chair considers that the information contained in the forms of proxy is sufficient to establish the entitlement of the Scheme Shareholder to vote and provided further that the Chair is satisfied as to the authority of the persons signing it to do so. In addition, the Chair shall seek the consent of the Court to be at liberty to accept any other forms of proxy or form of voting instructions that are customarily provided in relation to companies that are listed on Nasdaq.

(a) | Sending blue form of proxy by post

A blue form of proxy, for use at the Ortho Court Meeting, has been provided with this notice. Instructions for its use are set out on the form. It is requested that the blue form of proxy (together with any power of attorney or other authority, if any, under which it is signed, or a duly certified copy thereof) be returned in the pre-paid envelope provided by [Computershare], Ortho’s registrar, to [●], so as to be received as soon as possible and in any event not later than [●][a.m./ p.m.] (Eastern Standard Time) and [●] [a.m./ p.m.] (London time) on [●], 2022 (or, in the case of an adjournment of the Ortho Court Meeting, 48 hours (excluding any part of such 48-hour period falling on a non-working day) before the time appointed for the adjourned meeting).

If the blue form of proxy for the Ortho Court Meeting is not received by [Computershare], Ortho’s registrar, by the relevant time, it may be emailed to [●] or handed to the Chair at any time prior to the commencement of the Ortho Court Meeting otherwise it will be invalid.

(b) | Online appointment of proxies

As an alternative to completing and returning the printed blue form of proxy, proxies may be appointed electronically by logging on to the following website: [●] and following the instructions therein. Full details of the procedure to be followed to appoint a proxy electronically are given on the website. For an electronic proxy appointment to be valid, the appointment must be received by [Computershare], Ortho’s registrar, not later than 48 hours (excluding any part of such 48-hour period falling on a non-working day) before the time fixed for the Ortho Court Meeting or any adjournment thereof. If the electronic proxy appointment is not received by this time, the blue form of proxy may be emailed to [●] or handed to the Chair any time prior to the commencement of the Ortho Court Meeting or any adjournment thereof. Full details of the procedure to be followed to appoint a proxy electronically are given on the website referred to above.

(c) | Appointment of a proxy by joint holders

In the case of joint holders, where more than one of the joint holders purports to appoint one or more proxies, only the purported appointment submitted by the most senior holder will be accepted. For this purpose, seniority shall be determined by the order in which the names of the joint holders stand in the register of members of Ortho in respect of the joint holding.

4. | VOTES TO BE TAKEN BY A POLL AND RESULTS

At the Ortho Court Meeting, voting will be by poll rather than a show of hands. This is a more transparent method of voting as member votes are to be counted according to the number of ordinary shares held. The poll shall remain open for a period of thirty minutes following the discussion of the matters to be determined at the Ortho Court Meeting to enable Scheme Shareholders to amend their vote, if they so wish. The results of the poll will be announced by the filing of a Current Report on Form 8-K with the SEC and published on Ortho’s Internet website as soon as reasonably practicable following the conclusion of the Ortho Court Meeting.

Scheme Shareholders can either vote “FOR” or “AGAINST” the resolution approving the Scheme.

4. | RIGHT TO APPOINT A PROXY; PROCEDURE FOR APPOINTMENT

Ortho shareholders are strongly encouraged to submit proxy appointments and instructions for the Ortho General Meeting as soon as possible, using any of the methods (by hand, post or online) set out below. Ortho shareholders are also strongly encouraged to appoint the Chair of the Ortho General Meeting as their proxy. An Ortho shareholder entitled to attend and vote at the Ortho General Meeting may appoint one or more proxies to exercise all or any of such Ortho shareholder’s rights to attend, submit written questions and, on a poll, to vote (in each case, remotely, via the Virtual Meeting Platform), on their behalf. If any other person is appointed as proxy, he or she will not be permitted to attend the Ortho General Meeting in person, but will be able to attend, submit written questions and vote at the Ortho General Meeting remotely via the Virtual Meeting Platform as described above.

The completion and return of the white form of proxy by post (or appointment of a proxy online) will not prevent you from remotely attending, submitting questions and voting at the Ortho General Meeting, in each case via the Virtual Meeting Platform, if you are entitled to and wish to do so.

An Ortho shareholder entitled to attend and vote at the Ortho General Meeting may appoint one or more proxies to exercise all or any of such Ortho shareholder’s rights to attend, submit written questions and, on a poll, to vote (in each case, remotely, via the Virtual Meeting Platform), on their behalf. A proxy need not be an Ortho shareholder but must remotely attend the Ortho General Meeting for the Ortho shareholder’s vote to be counted. If an Ortho shareholder appoints more than one proxy to attend the meeting, each proxy must be appointed to exercise the rights attached to a different share or shares

held by the Ortho shareholder. If an Ortho shareholder wishes to appoint more than one proxy, the shareholder should contact [Computershare], Ortho’s registrar, for further white forms of proxy or photocopy the white form of proxy as required.

Ortho shareholders who do not appoint a proxy will still be entitled to remotely attend, submit written questions and vote at the Ortho General Meeting via the Virtual Meeting Platform.

(a) | Sending white form of proxy by post

A white form of proxy, for use at the Ortho General Meeting, has been provided with this notice. Instructions for its use are set out on the form. It is requested that the white form of proxy (together with any power of attorney or other authority, if any, under which it is signed, or a duly certified copy thereof) be returned in the pre-paid envelope provided by [Computershare], Ortho’s registrar, to [●], United Kingdom, so as to be received as soon as possible and in any event not later than [●] [a.m./ p.m.] (Eastern Standard Time) and [a.m./ p.m.] (London time) on [●], 2022 (or, in the case of an adjournment of the Ortho General Meeting, 48 hours (excluding any part of such 48-hour period falling on a non-working day) before the time appointed for the adjourned meeting).

If the white form of proxy for the Ortho General Meeting is not received by [Computershare], Ortho’s registrar, by the relevant time, it may be emailed to [●] or handed to the Chair at any time prior to the commencement of the Ortho General Meeting otherwise it will be invalid.

(b) | Online appointment of proxies

As an alternative to completing and returning the printed white form of proxy, proxies may be appointed electronically by logging on to the following website: [●] and following the instructions therein. Full details of the procedure to be followed to appoint a proxy electronically are given on the website referred to above. For an electronic proxy appointment to be valid, the appointment must be received by [Computershare], Ortho’s registrar, not later than 48 hours (excluding any part of such 48-hour period falling on a non-working day) before the time fixed for the Ortho General Meeting or any adjournment thereof. If the electronic proxy appointment is not received by this time, the white form of proxy may be emailed to [●] or handed to the Chair any time prior to the commencement of the Ortho General Meeting or any adjournment thereof. Full details of the procedure to be followed to appoint a proxy electronically are given on the website referred to above.

5. | APPOINTMENT OF A PROXY BY JOINT HOLDERS

In the case of joint holders, where more than one of the joint holders purports to appoint one or more proxies, only the purported appointment submitted by the most senior holder will be accepted. For this purpose, seniority shall be determined by the order in which the names of the joint holders stand in the register of members of Ortho in respect of the joint holding.

6. | CORPORATE REPRESENTATIVES

As an alternative to appointing a proxy, any Ortho shareholder which is a corporation may appoint one or more corporate representatives who may exercise on its behalf all of its powers, provided that if two or more representatives purport to vote in respect of the same shares: if they purport to exercise the power in the same way as each other, the power is treated as exercised in that way; and in other cases, the power is treated as not exercised.

7. | VOTES TO BE TAKEN BY A POLL AND RESULTS

At the Ortho General Meeting, voting on the resolutions will be by poll rather than a show of hands. This is a more transparent method of voting as member votes are to be counted according to the number of ordinary shares held. The poll shall remain open for a period of thirty minutes following the discussion of the matters to be determined at the Ortho General Meeting to enable Ortho shareholders to amend their vote, if they so wish. The results of the poll will be announced by the filing of a Current Report on Form 8-K with the SEC and published on Ortho’s Internet website as soon as reasonably practicable following the conclusion of the Ortho General Meeting.

The “WITHHELD” option on the form of proxy is provided to enable Ortho shareholders to abstain from voting on the resolutions. However, a vote withheld is not a vote in law and will not be counted in the calculation of proportion of votes “FOR” and “AGAINST” the resolutions.

8. | WEBSITE PROVIDING INFORMATION REGARDING THE ORTHO GENERAL MEETING

PROXY VOTING |  | It is important that your shares be represented and voted at the Quidel Stockholders’ Meeting. You can submit a proxy to vote your shares electronically via the Internet, by telephone or by completing and returning the proxy card or voting instruction card. Voting instructions are printed on your proxy card and are included in this joint proxy statement/prospectus. If your shares are held in the name of a bank, broker or other nominee, follow the instructions you receive from your nominee on how to vote your shares. You can revoke a proxy at any time prior to its exercise at the Quidel Stockholders’ Meeting by following the instructions in the joint proxy statement/prospectus or by voting your shares virtually at the Quidel Stockholders’ Meeting. Virtual attendance by stockholders of record at the Quidel Stockholders’ Meeting will constitute presence in person for the purpose of determining the presence of a quorum for the transaction of business at the Quidel Stockholders’ Meeting.

This joint proxy statement/prospectus describes the proposals listed above in more detail. Please refer to the attached document, including the BCA and all other annexes and any documents incorporated by reference herein, for further information with respect to the business to be transacted at the Quidel Stockholders’ Meeting.

Your proxy is being solicited by the Quidel board of directors. The Quidel board of directors has determined that the transactions to be implemented pursuant to the BCA (the “Combinations”), including the Quidel Merger and the other transactions contemplated by the BCA, are consistent with and will further the business strategies and goals of Quidel, and are in the best interests of Quidel and its stockholders, and (a) has unanimously approved and declared advisable the BCA and Combinations, including the Quidel Merger and the transactions contemplated by the BCA, and (b) has determined, subject to its duties under applicable law, to recommend that the Quidel stockholders adopt the BCA and the transactions contemplated by the BCA.

Accordingly, the Quidel board of directors recommends that Quidel stockholders vote:

| 1. | “FOR” the Merger Proposal;

| 2. | “FOR” the Advisory Merger Compensation Proposal;

| 3. | “FOR” the Adjournment Proposal;

| 4. | “FOR” the Election of Directors Proposal;

| 5. | “FOR” the Advisory Executive Compensation Proposal;

| 6. | “FOR” the Independent Registered Public Accounting Firm Proposal;

| 7. | “FOR” the Equity Incentive Plan Proposal; and

| 8. | “FOR” the ESPP Proposal.

The Quidel board of directors has fixed the close of business on March 14, 2022, as the record date for determining the Quidel stockholders entitled to receive notice of, and to vote at, the Quidel Stockholders’ Meeting. Only holders of record of shares of common stock of Quidel (each, a “Quidel Share”) at the close of business on the record date are entitled to receive notice of, and to vote at, the Quidel Stockholders’ Meeting.

Your vote is very important. Whether or not you plan to attend the Quidel Stockholders’ Meeting, we urge you to submit a proxy to vote by Internet or telephone to ensure that your shares are represented at the Quidel Stockholders’ Meeting. We cannot complete the Combinations unless you approve and adopt the BCA, the Quidel Merger and the Combinations.

A failure to submit a proxy or attend the Quidel Stockholders’ Meeting, a broker non-vote (if any) or an abstention will have the same effect as a vote “AGAINST” the Merger Proposal. A failure to submit a proxy or attend the Quidel Stockholders’ Meeting or a broker non-vote (if any) as to the Advisory Merger Compensation Proposal, the Adjournment Proposal, the Election of Directors Proposal, the Advisory Executive Compensation Proposal, the Independent Registered Public Accounting Firm Proposal, the Equity Incentive Plan Proposal or the ESPP Proposal will have no effect on these proposals. An abstention will have the same effect as a vote “AGAINST” the Advisory Merger Compensation Proposal, the Adjournment Proposal, the Election of Directors Proposal, the Advisory Executive Compensation Proposal, the Independent Registered Public Accounting Firm Proposal, the Equity Incentive Plan Proposal and the ESPP Proposal.

QUESTIONS AND ANSWERS ABOUT THE COMBINATIONS, THE QUIDEL STOCKHOLDERS’ MEETING AND THE ORTHO SHAREHOLDER MEETINGS

Q: | What is this document?

A: | This document, which we refer to as the “joint proxy statement/prospectus,” (i) serves as the proxy statement through which Quidel and Ortho will solicit proxies to seek to obtain the necessary Quidel stockholder and Ortho shareholder approvals for the Combinations, (ii) informs holders of Quidel Shares of the upcoming Quidel Stockholders’ Meeting at which Quidel stockholders will vote on the adoption of the BCA and the Quidel Merger and provides details of the BCA and the consideration Quidel stockholders will receive upon completion of the Combinations, (iii) informs holders of Ortho Shares of the upcoming Ortho Shareholder Meetings at which Ortho shareholders will vote on the Ortho Scheme, authorize the directors of Ortho (or a duly authorized committee of the directors) to take all such action as they may consider necessary or appropriate for carrying the Ortho Scheme into effect, amend the articles of association of Ortho and approve (on a non-binding, advisory basis) certain compensation that may be paid or become payable to Ortho’s named executive officers in connection with the Combinations, as disclosed in the table entitled “Interests of Certain Persons in the Combinations (Ortho)—Golden Parachute Compensation,” (iv) provides details of the BCA and the consideration Ortho shareholders will receive upon completion of the Combinations, (v) serves as the prospectus by which Topco will issue Topco Shares to Quidel stockholders and Ortho shareholders in connection with the Combinations and (vi) provides Quidel stockholders and Ortho shareholders with important details about Topco and their rights as potential holders of Topco Shares.

Q: | What is the proposed transaction I am being asked to vote on, and how will it be implemented?

A: | On December 22, 2021, Quidel entered into the BCA with Ortho, Topco, U.S. Holdco Sub, U.S. Merger Sub and U.S. Holdco Sub 2, which provides for the acquisition of Ortho and Quidel by Topco. Pursuant to the BCA, the Combinations are expected to be implemented by way of:

(i) a scheme of arrangement to be undertaken by Ortho under Part 26 of the UK Companies Act (the “Ortho Scheme”), pursuant to which the Scheme Shares will be acquired by a nominee of Topco (or, if such nominee holds the Ortho Shares today, transferred within the nominee), such that Ortho will become a wholly owned subsidiary of Topco; and

(ii) a merger (the “Quidel Merger”) of U.S. Merger Sub with and into Quidel immediately following consummation of the Ortho Scheme, with Quidel surviving the merger as a wholly owned subsidiary of Topco (the transactions in (i) and (ii) together, the “Combinations”).

For more information about the Ortho Scheme, see the sections entitled “Scheme Proposal and the Ortho Shareholder Meetings—Explanatory Statement” and “The Ortho Scheme” of this joint proxy statement/prospectus. For more information about the Quidel Merger, see the section entitled “The Quidel Stockholders’ Meeting—Proposal No. 1—The Merger” of this joint proxy statement/prospectus.

Q: | Why are Quidel and Ortho proposing this transaction?

A: | The board of directors of each of Quidel and Ortho believes that the transaction will benefit Quidel stockholders and Ortho shareholders by creating a combined company that will bring together innovative and highly complementary diagnostic portfolios with world-class technologies and platforms that enhance the health and well-being of patients across the globe.

For more details on the reasons for the transaction, see the sections entitled “The Combinations—Quidel Reasons for the Combinations and Recommendation of the Quidel Board of Directors” and “The Combinations—Ortho Reasons for the Combinations and Recommendation of the Ortho Board of Directors” of this joint proxy statement/prospectus.

Q: | Why did I receive this joint proxy statement/prospectus and proxy card?

A: | You are receiving this joint proxy statement/prospectus because you were a stockholder of record of Quidel on the record date for the Quidel Stockholders’ Meeting and/or a shareholder of record of Ortho on the record date for the Ortho Court Meeting and Ortho General Meeting, and are accordingly entitled to vote at the Quidel Stockholders’ Meeting, the Ortho Court Meeting or the Ortho General Meeting (as applicable). This document serves (i) as a proxy

1

| statement of Quidel used to solicit proxies to obtain the necessary stockholder approval for the Merger Proposal, the Adjournment Proposal, the Election of Directors Proposal, the Independent Registered Public Accounting Firm Proposal, the Equity Incentive Plan Proposal and the ESPP Proposal and the approval (on a non-binding, advisory basis) for the Advisory Merger Compensation Proposal and the Advisory Executive Compensation Proposal at the Quidel Stockholders’ Meeting, (ii) as a proxy statement of Ortho used to solicit proxies to obtain the necessary shareholder approval for the Ortho Scheme at the Ortho Court Meeting and for the general authorization of the directors of Ortho (or a duly authorized committee of the directors) to take all such action as they may consider necessary or appropriate for carrying the Ortho Scheme into effect, the adoption of new Ortho articles of association and the approval (on a non-binding, advisory basis) of certain compensation arrangements at the Ortho Shareholder Meetings, and (iii) as a prospectus of Topco used to offer Topco Shares in exchange for Quidel Shares and Ortho Shares pursuant to the terms of the BCA. The enclosed voting materials allow both Quidel stockholders and Ortho shareholders to vote their shares by proxy without attending their respective meeting virtually.

Q: | What will Quidel stockholders and Ortho shareholders receive in the Combinations?

A: | If the Combinations are approved, at the effective time of the Ortho Scheme (the “Ortho Effective Time”), each Ortho Share, other than Ortho Shares held by Ortho in treasury, if any, will be acquired by a nominee (or, if such nominee holds the Ortho Shares today, transferred within the nominee) on behalf and for the benefit of Topco in exchange for 0.1055 Topco Shares and $7.14 in cash. At the effective time of the Quidel Merger (the “Quidel Effective Time” and together with the Ortho Effective Time, the “Effective Times”), each share of common stock of Quidel (each, a “Quidel Share”), other than Quidel Shares held by Quidel, Ortho or U.S. Merger Sub, will be converted into the right to receive one Topco Share. The parties intend to list the Topco Shares to be issued in the Combinations on the Nasdaq Global Select Market (“Nasdaq”).

Q: | What percentage will former Quidel stockholders and Ortho shareholders hold in Topco following completion of the Combinations?

A: | It is anticipated that, immediately following completion of the Combinations, former Quidel stockholders will own approximately 62% of Topco on a fully diluted basis and former Ortho shareholders will own approximately 38% of Topco on a fully diluted basis, based on the respective capitalizations of Quidel and Ortho as of the date the parties entered into the BCA. The exact equity stakes that former Quidel stockholders and former Ortho shareholders will hold in Topco immediately following the Combinations will depend on the number of Quidel Shares and Ortho Shares issued and outstanding immediately prior to the Effective Times.

Q: | If the Combinations are completed, will Topco Shares be listed for trading?

A: | Yes. The Topco Shares you will receive in the Combinations are expected to be listed on Nasdaq as of the completion of the Combinations, which will occur on the date of the Effective Times. Completion of the Combinations is subject to the Topco Shares being approved for listing on Nasdaq, subject to official notice of issuance. Topco Shares received in the Combinations are expected to be freely transferable under applicable securities laws (subject to any applicable minimum holding period in respect of Topco Shares received in exchange for Quidel Shares or Ortho Shares delivered upon vesting of certain equity awards), except for any Topco Shares held by Topco’s affiliates.

Q: | How will fractional entitlements to Topco Shares be dealt with?

A: | Fractions of Topco Shares that Scheme Shareholders would otherwise be entitled to will not be allotted to Scheme Shareholders. Instead, Scheme Shareholders will receive, in lieu of such fractional entitlements, cash in an amount in U.S. dollars (rounded down to the nearest cent) equal to such fractional amount multiplied by the aggregate net proceeds from the sale of all such fractional entitlements. The Exchange Agent will orchestrate the sale of the fractional entitlements on Nasdaq in the ten Business Days following the Scheme Effective Date (as defined herein).

Q: | When do you expect the Combinations to be completed?

A: | The Combinations are expected to close before the end of the first half of 2022, subject to the approvals of Quidel stockholders and Ortho shareholders, receipt of regulatory approvals and consents and satisfaction of other closing conditions.

2

Q: | What happens if the Combinations are not completed?

A: | If Quidel stockholders do not approve the Merger Proposal, if the Ortho shareholders do not approve the Ortho Scheme or if the Combinations are not completed for any other reason, Quidel and Ortho will remain independent companies. In the event of a termination, Quidel Shares and Ortho Shares will continue to be listed and traded individually on Nasdaq and both Quidel and Ortho will continue to be registered under the Exchange Act and file periodic reports with the SEC.

Quidel or Ortho may each terminate the BCA under certain circumstances, including, among others, where the other party breaches its representations, warranties or covenants contained in the BCA (subject to customary materiality thresholds and cure periods). In connection with the termination of the BCA under specified circumstances, Quidel or Ortho may be required to pay the other party a termination fee of approximately $207.8 million, in the case of payment by Quidel, or approximately $46.9 million, in the case of payment by Ortho, or may be required to reimburse the other party for its out-of-pocket expenses incurred in connection with the BCA.

Q: | What regulatory approvals are needed to complete the Combinations?

A: | Quidel and Ortho have agreed to use their reasonable best efforts to obtain all regulatory approvals required to complete the transactions contemplated by the BCA. These approvals include clearance under the U.S. Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and other merger control and foreign investment laws and regulations. Quidel and Ortho have completed, or will complete, the filing of applications and notifications to obtain the required regulatory approvals.

For further details on regulatory approvals, see the section entitled “The Combinations—Antitrust and Merger Control” of this joint proxy statement/prospectus.

Q: | What other conditions must be satisfied to complete the Combinations?

A: | In addition to Quidel stockholder and Ortho shareholder approvals and clearance from antitrust, competition and foreign investment authorities in certain areas where Quidel and Ortho operate, closing of the Combinations is subject to certain additional conditions, including (i) the absence of any law or order prohibiting the Combinations, (ii) effectiveness of a registration statement for the Topco Shares to be issued in the Combinations, (iii) Nasdaq listing approval for Topco Shares and (iv) sanction of the Ortho Scheme by the High Court of Justice of England and Wales (the “Court”) and the delivery of the order of the Court sanctioning the Ortho Scheme to the Registrar.

Q: | What are the U.S. federal income tax considerations to Quidel stockholders and Ortho shareholders of the Combinations?

A: | The exchange of Quidel Shares for Topco Shares pursuant to the Quidel Merger, taken together with the Ortho Scheme, will qualify as a transaction described in Section 351 of the Internal Revenue Code of 1986, as amended (the “Code”). As a result, subject to the limitations and qualifications described in the section entitled “Material U.S. Federal Income Tax Considerations” of this joint proxy statement/prospectus no gain or loss is expected to be recognized by the U.S. Holders of Quidel Shares as a result of the Quidel Merger.

The exchange of Ortho Shares for Topco Shares and cash pursuant to the Ortho Scheme, taken together with the Quidel Merger, will qualify as a transaction described in Section 351 of the Code. As a result, subject to the limitations and qualifications described in the section entitled “Material U.S. Federal Income Tax Considerations” of this joint proxy statement/prospectus, gain (but not loss) is expected to be recognized on the exchange of Ortho Shares for a combination of cash and Topco Shares pursuant to the Ortho Scheme in an amount equal to the lesser of: (a) the excess of (i) the sum of the fair market value of the Topco Shares and the amount of cash received by such U.S. Holder over (ii) such U.S. Holder’s tax basis in its Ortho Shares, and (b) the amount of cash received by such U.S. Holder pursuant to the Ortho Scheme. The treatment of the cash received in lieu of fractional Topco Shares is discussed separately in the section entitled “Material U.S. Federal Income Tax Considerations” of this joint proxy statement/prospectus.

Please carefully review the information set forth in the section entitled “Material U.S. Federal Income Tax Considerations” of this joint proxy statement/prospectus for a general discussion of material U.S. federal income tax considerations relating to the Quidel Merger and the Ortho Scheme. You are strongly urged to consult your tax advisors as to the specific tax consequences to you.

3

Q: | What are the UK tax considerations to shareholders of the Combinations?

A: | See the section entitled “Material UK Tax Considerations” of this joint proxy statement/prospectus.

Q: | As Ortho is a UK public limited company, do the UK rules on takeovers apply to the proposed Combinations?

A: | The UK Panel on Takeovers and Mergers has confirmed that the City Code on Takeovers and Mergers (the “City Code”) will not apply to any transaction involving Ortho (including the Combinations) because the place of central management and control of Ortho for purposes of the City Code is outside of the UK, the Isle of Man and the Channel Islands.

Q: | Are either Quidel stockholders or Ortho shareholders entitled to exercise dissenters’, appraisal, cash exit, or similar rights?

A: | No. Neither Quidel stockholders nor Ortho shareholders are entitled to appraisal or dissenters’ rights in connection with the transaction.

Q: | What impact will the Ortho Scheme have on Ortho mandates relating to the payment of dividends?

A: | Any mandates relating to the payment of dividends on any Scheme Shares and other instructions (including communications preferences) given to Ortho by Scheme Shareholders in force at the Scheme Record Time relating to Scheme Shares will, as from the Scheme Effective Date, cease to be valid.

Q: | As an Ortho shareholder, why did I receive two forms of proxy?

A: | Ortho shareholders are entitled to vote at two meetings, the Ortho Court Meeting and the Ortho General Meeting. Each Ortho shareholder received a blue form of proxy for use in respect of the Ortho Court Meeting and a white form of proxy for use in respect of the Ortho General Meeting.

Q: | Whose proxies are being solicited and who is entitled to vote at the Quidel Stockholders’ Meeting and the Ortho Shareholder Meetings?

A: | Only Quidel stockholders are entitled to vote at the Quidel Stockholders’ Meeting and only Ortho shareholders are entitled to vote at the Ortho Court Meeting and Ortho General Meeting. The record date for the Quidel Stockholders’ Meeting is March 14, 2022. Only holders of record of Quidel Shares as of the close of business on the record date are entitled to notice of, and to vote at, the Quidel Stockholders’ Meeting. Each holder of Quidel Shares is entitled to cast one vote on each matter properly brought before the Quidel Stockholders’ Meeting for each Quidel Share that such holder owned of record as of the close of business on the record date.

The Voting Record Time for the Ortho Shareholder Meetings is [●] [a.m./ p.m.] (Eastern Standard Time) and [6:00] p.m. (London time) on [●], 2022. Only those shareholders registered on the register of members of Ortho as of such time are entitled to vote at the Ortho Shareholder Meetings. Each holder of Ortho Shares is entitled to cast one vote on each matter properly brought before the Ortho Court Meeting and one vote on each matter properly brought before the Ortho General Meeting for each Ortho Share that such holder owned of record as of the Voting Record Time.

Q: | What do I need to do now?

A: | Carefully read through this joint proxy statement/prospectus. Consider all the consequences that would occur should you vote “FOR” or “AGAINST” or “ABSTAIN” / “WITHHELD” on the proposals at the Quidel Stockholders’ Meeting if you are a Quidel stockholder, or at the Ortho Court Meeting or the Ortho General Meeting (as applicable) if you are an Ortho shareholder, and the consequences that would occur if you fail to submit a proxy. Confer with any advisors you think necessary to make the best decision. Fill out your proxy card(s) and send it back to Quidel or Ortho, as applicable, as soon as possible in accordance with the instructions contained herein.

Even if you plan to attend the Quidel Stockholders’ Meeting, the Ortho Court Meeting or the Ortho General Meeting (as applicable), after carefully reading and considering the information contained in this joint proxy statement/prospectus, please submit your proxy promptly to ensure that your shares are represented at the respective meeting(s). If you decide to attend the meeting(s) and vote virtually, your vote by ballot will revoke any proxy previously submitted. Your attendance at a meeting will not automatically revoke your proxy. Both the Quidel Stockholders’ Meeting and the Ortho Shareholder Meetings will be entirely virtual.

If you are a beneficial owner (i.e., hold Quidel Shares or Ortho Shares in “street name”), please refer to the instructions provided by your bank, brokerage firm or other nominee to see which of the above choices are available to you. Please note that if you are a beneficial owner and wish to vote virtually at your respective meeting(s), you must obtain a legal proxy from your bank, brokerage firm or other nominee.

Q: | Do I need to do anything with my Quidel Shares or my Ortho Shares other than voting for the proposals at the Quidel Stockholders’ Meeting, the Ortho Court Meeting or the Ortho General Meeting?

A: | No. You do not need to take any action at this time with respect to your shares. Please do not send your stock certificates, if any, with your proxy card.

Q: | What happens if I sell my Quidel Shares before the Quidel Stockholders’ Meeting, or sell my Ortho Shares before the Ortho Court Meeting and Ortho General Meeting?

A: | The record date for the Quidel Stockholders’ Meeting and the Voting Record Time for the Ortho Shareholder Meetings is earlier than the date of each such meeting and the date that the Combinations are expected to be completed. If you transfer your shares after the record date or Voting Record Time, as applicable, but before the Quidel Stockholders’ Meeting, the Ortho Court Meeting or the Ortho General Meeting, as applicable, you will, unless the transferee receives a proxy from you, retain your right to vote at the respective meeting(s), but you will have transferred the right to receive the consideration in connection with the Combinations. In order to receive the consideration, you must hold your Quidel Shares or Ortho Shares through the Quidel Effective Time or the Ortho Effective Time, as applicable.

Q: | What is the recommendation of the board of directors of Quidel as to each proposal that may be voted on at the Quidel Stockholders’ Meeting?

A: | The Quidel board of directors has determined that the Combinations, including the Quidel Merger and the other transactions contemplated by the BCA, are consistent with and will further the business strategies and goals of Quidel, and are in the best interests of Quidel and its stockholders, and (a) has unanimously approved and declared advisable the BCA and Combinations, including the Quidel Merger and the transactions contemplated by the BCA, and (b) has determined, subject to its duties under applicable law, to recommend that the Quidel stockholders adopt the BCA and the transactions contemplated by the BCA.

Accordingly, the Quidel board of directors recommends that Quidel stockholders vote:

| 1. | “FOR” the Merger Proposal;

| 2. | “FOR” the Advisory Merger Compensation Proposal;

| 3. | “FOR” the Adjournment Proposal;

| 4. | “FOR” the Election of Directors Proposal;

| 5. | “FOR” the Advisory Executive Compensation Proposal;

| 6. | “FOR” the Independent Registered Public Accounting Firm Proposal;

| 7. | “FOR” the Equity Incentive Plan Proposal; and

| 8. | “FOR” the ESPP Proposal.

See the sections entitled “Other Matters Relating to the Quidel Stockholders’ Meeting” and “The Combinations—Quidel Reasons for the Combinations and Recommendation of the Quidel Board of Directors” of this joint proxy statement/prospectus.

Q: | What is the recommendation of the board of directors of Ortho as to each proposal that may be voted on at the Ortho Court Meeting and Ortho General Meeting?

A: | The Ortho board of directors considers the terms of the Ortho Scheme to be in the best interests of Ortho and its shareholders taken as a whole.

5

Accordingly, the Ortho board of directors recommends that Ortho shareholders vote:

| 1. | “FOR” the approval of the Scheme of Arrangement at the Ortho Court Meeting; and

| 2. | “FOR” the approval of each of the resolutions at the Ortho General Meeting.

See the section entitled “The Combinations—Ortho Reasons for the Combinations and Recommendation of the Ortho Board of Directors” of this joint proxy statement/prospectus.

Q: | What votes of the Quidel stockholders and the Ortho shareholders are required to approve the proposals presented at the Quidel Stockholders’ Meeting, the Ortho Court Meeting and the Ortho General Meeting?

A: | At the Quidel Stockholders’ Meeting, approval of the Merger Proposal requires the affirmative vote of the holders of a majority of the outstanding Quidel Shares entitled to vote on such matter in person (virtual attendance by stockholders of record at the Quidel Stockholders’ Meeting will constitute presence in person for the purpose of determining the number of votes cast) or represented by proxy at the Quidel Stockholders’ Meeting, voting as a single class.

At the Ortho Court Meeting, approval of the Ortho Scheme requires the affirmative vote by a majority in number representing 75% in value of the holders of Ortho Shares who vote in person (virtual attendance by shareholders of record at the Ortho Court Meeting will constitute presence in person for the purpose of determining the number of votes cast) or by proxy at the Ortho Court Meeting. At the Ortho General Meeting, approval of each proposal to be considered at the Ortho General Meeting and passed as an ordinary resolution requires the affirmative vote of a majority of the voting rights represented at the Ortho General Meeting in person or by proxy and entitled to vote on such proposal, and approval of each proposal to be considered at the Ortho General Meeting and passed as a special resolution requires the affirmative vote of not less than 75% of the votes cast by Ortho shareholders present (in person or by proxy) at the meeting and entitled to vote on such proposal.

Q: | Will the Scheme Shareholders vote as one class at the Ortho Court Meeting?

A: | At a directions hearing on February 15, 2022 the Court confirmed that the Scheme Shareholders (as defined in the Scheme of Arrangement) should be treated by Ortho as a single class of shareholders for the purpose of voting at the Ortho Court Meeting to approve the Ortho Scheme. In accordance with section 899 of the Companies Act 2006 (the “Act”) the Ortho Scheme must be approved by a majority of shareholders in number (the “majority in number test”) representing three-quarters or more in value of the shareholders who vote in person or by proxy (the “value test”).

Majority in Number Test

At a directions hearing on February 15, 2022 the Court confirmed that for the purpose of the majority in number test, Ortho shall treat a holder of Scheme Shares that casts votes both ‘for’ and ‘against’ the Ortho Scheme as voting in favour of the Ortho Scheme if such holder casts more votes ‘for’ the Ortho Scheme than ‘against’ the Ortho Scheme and otherwise, against.

If Ortho’s register of members remains unchanged, it is anticipated that at the Ortho Court Meeting Ortho shall have two registered shareholders, and the holders of the Scheme Shares shall be Cede & Co., as depositary nomine of The Depositary Trust Company (“DTC”) and GTU Ops, Inc., as nominee of Computershare (“Computershare”). Accordingly, provided that a majority of the votes cast in respect of the Scheme Shares held by Computershare are voted ‘for’ the Ortho Scheme, Computershare shall be considered to have voted in favour of the Ortho Scheme. Similarly, if a majority of the votes cast in respect of the Scheme Shares held by DTC are voted ‘for’ the Ortho Scheme, DTC shall be considered to have voted in favour of the Ortho Scheme.

As at March 4, 2022 Carlyle Partners VI Cayman Holdings, L.P. (“Carlyle”) held 118,106,000 ordinary shares in the share capital of Ortho via Computershare and Computershare held a total of 120,252,074 ordinary shares in the share capital of Ortho. Therefore, if Carlyle votes in favour of the Ortho Scheme 98.2% of the ordinary shares held by Computershare will be voted in favour of the Scheme and, as this constitutes a majority, Computershare will be deemed to have voted ‘for’ the Ortho Scheme. As at March 4, 2022 DTC held 117,297,848 ordinary shares in the share capital of Ortho. Assuming that each ordinary share held by DTC is voted at the Ortho Court Meeting, 58,648,925 of such ordinary shares in the share capital of Ortho would need to vote in favour of the Ortho Scheme in order for DTC to be considered to have voted in favour of the Ortho Scheme. It is possible that not all of the shares held via DTC will be voted at the Ortho Court Meeting; however, provided a majority of the shares that actually vote are voted in favour of the Ortho Scheme DTC shall be considered to have voted in favour of the Ortho Scheme.

6

It is only possible for existing beneficial holders of Ortho Shares to attend and vote directly (i.e., in their own name) at the Ortho Court Meeting (or Ortho General Meeting) in respect of all or part of their holding, if they become a registered holder of Ortho Shares. In the event that Ortho has additional registered shareholders on its register of members as at the Voting Record Time, then it is expected that the Court will continue to require that a majority in number of all such voting holders (irrespective of the size of their shareholding) vote ‘for’ the Ortho Scheme than ‘against’ the Ortho Scheme. Beneficial holders of shares of Ortho Shares may arrange to become a registered holder of Ortho Shares upon completion of a stock transfer form by the applicable registered holder nominee (DTC or Computershare) in respect of the Ortho Shares that they wish to be transferred into their name (and pay any related UK stamp duty, if applicable) and send the completed stock transfer form and related documentation (as applicable) to Ortho’s transfer agent, Computershare Investor Services at Investor Services at 462 South 4th Street, Suite 1600, Louisville, KY, 40202, United States, to permit processing to be completed by Computershare prior to the Voting Record Time.

Value Test

As at March 4, 2022 Ortho had 237,549,922 ordinary shares in issue. Assuming that each of such ordinary shares is voted at the Ortho Court Meeting, and if Carlyle votes in favour of the Ortho Scheme in respect of the 118,106,000 ordinary shares it holds via Computershare, Carlyle will account for 49.7% for the purpose of the value test. Assuming that each of the remaining 119,443,922 ordinary shares vote at the Ortho Court Meeting, at least 60,056,442 of such ordinary shares (representing 50.3% of the ordinary shares not held by Carlyle and 25.3% of the total ordinary shares) would need to vote in favour of the Ortho Scheme in order for the value test to be passed. As stated above, it is possible that not all of the ordinary shares held by shareholders other than Carlyle will vote at the Ortho Court Meeting and, as a result, Carlyle’s vote would represent a larger proportion of the three-quarters in value required to pass the value test. As a result, until the number of votes cast at the Ortho Court Meeting are known it is not possible to state how many ordinary shares held other than by Carlyle would need to vote in favour of the Ortho Scheme in order to pass the value test (unless every ordinary share not held by Carlyle votes at the Ortho Court Meeting—as described in the calculation above).

Q: | What are the effects of abstentions and broker non-votes at the Quidel Stockholders’ Meeting, the Ortho Court Meeting and the Ortho General Meeting?

A: | In connection with the Quidel Stockholders’ Meeting, abstentions and broker non-votes (if any) will be considered in determining the presence of a quorum. An abstention occurs when a stockholder abstains from voting (either in person or by proxy) on one or more of the proposals. Broker non-votes occur when a broker, bank, trust or other nominee returns a proxy but does not have authority to vote on a particular proposal. You should therefore provide your broker, bank, trust or other nominee with instructions as to how to vote your Quidel Shares or Ortho Shares (as applicable).

A failure to submit a proxy or attend the Quidel Stockholders’ Meeting, a broker non-vote (if any) or an abstention will have the same effect as a vote “AGAINST” the Merger Proposal. A failure to submit a proxy or attend the Quidel Stockholders’ Meeting or a broker non-vote (if any) as to the Advisory Merger Compensation Proposal, the Adjournment Proposal, the Election of Directors Proposal, the Advisory Executive Compensation Proposal, the Independent Registered Public Accounting Firm Proposal, the Equity Incentive Plan Proposal or the ESPP Proposal will have no effect on these proposals. An abstention will have the same effect as a vote “AGAINST” the Advisory Merger Compensation Proposal, the Adjournment Proposal, the Election of Directors Proposal, the Advisory Executive Compensation Proposal, the Independent Registered Public Accounting Firm Proposal, the Equity Incentive Plan Proposal and the ESPP Proposal.

In connection with the Ortho Shareholder Meetings, abstentions and broker non-votes will be considered in determining the presence of a quorum. However, abstentions and broker non-votes are not considered votes cast under the UK Companies Act. An abstention occurs when an Ortho shareholder abstains from voting (either in person or by proxy) on one or more of the proposals. Broker non-votes occur when a broker, bank, trust or other nominee returns a proxy but does not have authority to vote on a particular proposal. As a result, for purposes of determining whether each of the resolutions set out in the Notice of Ortho Court Meeting and Notice of Ortho General Meeting has been approved in accordance with the UK Companies Act, abstentions and broker non-votes will not have any effect on the outcome of the vote.

Q: | If I am a stockholder of record for either Quidel Shares or Ortho Shares, how do I vote?

A: | If you are the stockholder of record with respect to your Quidel Shares or Ortho Shares, you may vote virtually at the Quidel Stockholders’ Meeting, the Ortho Court Meeting or the Ortho General Meeting (as applicable) or by proxy. Virtual

7

| attendance by stockholders of record at the Quidel Stockholders’ Meeting will constitute presence in person for the purpose of determining the presence of a quorum for the transaction of business at the Quidel Stockholders’ Meeting.

If you do not wish to vote virtually or if you will not be attending your respective meeting(s), you may submit a proxy. You can vote by proxy over the Internet by going to www.proxyvote.com, by mail by returning the proxy card or by telephone by calling the number listed on your proxy card for your respective meeting(s) and, in each case, following the instructions provided. Even if you plan to attend the Quidel Stockholders’ Meeting, the Ortho Court Meeting and/or the Ortho General Meeting and vote virtually (as applicable), we recommend you submit a proxy so your vote will be counted even if your plans change.

Both Quidel and Ortho provide Internet proxy voting to allow you to submit a proxy to vote your Quidel Shares or Ortho Shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions.

Q: | If I am a beneficial owner of either Quidel Shares or Ortho Shares held in street name, how do I vote?

A: | If, on the Quidel record date, your shares were held in an account at a brokerage firm, bank, broker-dealer or other similar organization, then you are the beneficial owner of shares held in “street name,” and the organization holding your account is considered the stockholder of record for purposes of voting at the Quidel Stockholders’ Meeting.

If you are a beneficial owner of Quidel Shares registered in the name of your broker, bank, dealer or other similar organization and you wish to vote in person at the Quidel Stockholders’ Meeting, you must obtain a valid proxy from the organization that holds your Quidel Shares. If you do not wish to vote in person or you will not be attending the Quidel Stockholders’ Meeting, you should have received a proxy card and voting instructions with this joint proxy statement/prospectus from that organization. Please follow the voting instructions provided by your broker, bank, dealer or other similar organization to ensure that your vote is counted. Virtual attendance by stockholders of record at the Quidel Stockholders’ Meeting will constitute presence in person for the purpose of determining the presence of a quorum for the transaction of business at the Quidel Stockholders’ Meeting.

If your Ortho Shares are held through a broker, bank, trust company or other nominee and you wish to access the Virtual Meeting Platform, you will need to contact your broker, bank, trust company or other nominee immediately. Your broker, bank, trust company or other nominee will need to have completed a [letter of representation] and presented this to [Computershare], Ortho’s registrar, no later than 72 hours before the start of the meeting in order to obtain your unique login code and PIN number to access the Virtual Meeting Platform. Holders of the beneficial interests in Ortho Shares will be able to submit written questions by email to IR@orthoclinicaldiagnostics.com (emails must be received no less than 48 hours before the start of the Ortho Shareholder Meetings) and observe the Ortho Shareholder Meetings remotely via the Virtual Meeting Platform. Please see the section entitled “Scheme Proposal and the Ortho Shareholder Meetings—Explanatory Statement—Beneficial Holders” of this joint proxy statement/prospectus for further information in respect of such holdings and interests. If you are in any doubt about your shareholding, please contact [Computershare], Ortho’s registrar, at [●].

Q: | What happens if I am an Ortho shareholder located outside of the United States?

A: | The availability of the Ortho Scheme and the transaction deliverables to overseas Ortho shareholders (i.e., those outside the United States) may be affected by the laws of the relevant jurisdictions. Overseas Ortho shareholders should inform themselves about, and should observe, any applicable legal requirements. It is the responsibility of all overseas Ortho shareholders to satisfy themselves as to their full compliance with the laws of the relevant jurisdiction, including obtaining any governmental, exchange control or other consents which may be required and their compliance with any other necessary formalities which are required to be observed and the payment of any issue, transfer or other taxes due in such jurisdiction. If you are in any doubt regarding such matters, you should consult an independent professional adviser in the relevant jurisdiction without delay. Overseas Ortho shareholders should consult their own legal and tax advisers with respect to the legal and tax consequences of the Combinations in their particular circumstances.

Q: | What happens if I hold both Quidel Shares and Ortho Shares?

A: | You will receive separate proxy or voting instruction cards for each of the Quidel Stockholders’ Meeting, the Ortho Court Meeting and the Ortho General Meeting (as applicable), and are advised to complete, sign and date each proxy or voting instruction card and return each proxy or voting instruction card in the appropriate postage-paid envelope or, if available, submit a proxy or voting instruction by telephone or through the Internet for each company.

8

Q: | How do I appoint a proxyholder?

A: | Your proxyholder is the person you appoint to cast your votes on your behalf at the Quidel Stockholders’ Meeting, the Ortho Court Meeting or the Ortho General Meeting (as applicable), if you do not attend and vote virtually. You can choose anyone you want to be your proxyholder; it does not have to be the persons Quidel or Ortho has designated. To designate a different person to be your proxyholder, if you are a holder of Quidel Shares, write in the name of the person you would like to appoint in the blank space provided in the proxy card and, if you are a holder of Ortho Shares, contact [Computershare], Ortho’s registrar, at [●]. An Ortho shareholder entitled to attend and vote at the Ortho Court Meeting and Ortho General Meeting may appoint one or more proxies to exercise all or any of such Ortho shareholder’s rights to attend, submit written questions and, on a poll, to vote (in each case, remotely, via the Virtual Meeting Platform), on their behalf. Please ensure that the person you have appointed will be attending the Quidel Stockholders’ Meeting, the Ortho Court Meeting or the Ortho General Meeting (as applicable) and is aware that he or she will be voting your shares.

If you sign the proxy card without naming your own proxyholder and you are a holder of Quidel Shares, you thereby appoint [●] as your proxyholders, who will be authorized to vote and otherwise act for you at the Quidel Stockholders’ Meeting in accordance with the instructions on the proxy card. If you sign the proxy card without naming your own proxyholder and you are a holder of Ortho Shares, you thereby appoint the Chair of Ortho as your proxyholder, who will be authorized to vote and otherwise act for you at the Ortho General Meeting, but not the Ortho Court Meeting, in accordance with the instructions on the proxy card.

Q: | How many proxies can I appoint?

A: | An Ortho shareholder of record may appoint one or more proxies to exercise all or any of such Ortho shareholder’s rights to attend, submit written questions and, on a poll, to vote (in each case, remotely, via the Virtual Meeting Platform), on their behalf. If an Ortho shareholder of record appoints more than one proxy to attend the meeting, each proxy must be appointed to exercise the rights attached to a different share or shares held by such shareholder. If an Ortho shareholder of record wishes to appoint more than one proxy, they should contact [Computershare], Ortho’s registrar, for additional blue/white forms of proxy or photocopy the blue/white form of proxy as required.

Q: | How will my shares be voted at the Ortho Court Meeting and the Ortho General Meeting if I submit my proxy?

A: | On the proxy card, you can indicate how you want your proxyholder to vote your shares. If you have specified on the proxy card how you want to vote on a particular proposal (by marking as applicable “FOR” or “AGAINST”), then your proxyholder must vote your shares accordingly. With respect to the Ortho General Meeting, but not the Ortho Court Meeting, you can let your proxyholder decide for you by signing and returning the proxy card without indicating a voting preference for one or all proposals. With respect to the Ortho Court Meeting, if you sign your proxy card without giving instructions, you will have granted authority to your proxy to vote “FOR” each of the Scheme Implementation Proposal and the Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements but not the Scheme Proposal.

Q: | When should I submit my proxy?

A: | You should submit your proxy as soon as possible so that your shares will be voted at the Quidel Stockholders’ Meeting, the Ortho Court Meeting or the Ortho General Meeting (as applicable). If you are either a Quidel stockholder of record or an Ortho shareholder of record, your proxy must be received by Internet or telephone (in the case of Quidel only) before the Quidel Stockholders’ Meeting, or by hand, email or post (in the case of Ortho only) before the Ortho Court Meeting or the Ortho General Meeting (as applicable) in order for your shares to be voted at the applicable meeting(s). If you are either a Quidel stockholder of record or an Ortho shareholder of record and you received a printed set of proxy materials, you also have the option of completing and returning the proxy card enclosed with the proxy materials so that it is received by Quidel or Ortho, respectively, before the respective meeting(s) in order for your shares to be voted at the meeting. If you hold your shares in street name through a broker, bank or other nominee, please comply with the deadlines included in the voting instructions provided by the broker, bank or other nominee that holds your shares. For a proxy appointment to be valid in respect of the Ortho Court Meeting and the Ortho General Meeting, the appointment must be received by [Computershare], Ortho’s registrar, not later than 48 hours (excluding any part of such 48-hour period falling on a non-working day) before the time fixed for the Ortho Court Meeting and the Ortho General Meeting or any adjournment thereof. If the appointment is not received by [Computershare], Ortho’s registrar, by the relevant time, it may be emailed to [•] or handed to the Chair at any time prior to the commencement of the Ortho Court Meeting and Ortho General Meeting, as applicable, otherwise it will be invalid.

9

Q: | Can I change my vote or revoke my proxy after I have returned a proxy or voting instruction card?

A: | Yes. You may revoke your proxy and change your vote at any time before the final vote at the Quidel Stockholders’ Meeting, the Ortho Court Meeting or the Ortho General Meeting (as applicable). The most recent proxy card or telephone (in the case of Quidel only) or Internet proxy received by the inspector of elections (for Quidel) or registrar (for Ortho) for each meeting is the one that is counted.

Quidel Stockholder of Record: If you are a Quidel stockholder of record, you may revoke your proxy or change your vote in any one of the following ways:

| • |  | you may send a written notice that you are revoking your proxy to Quidel’s Secretary at Quidel Corporation, Attention: Phillip S. Askim, 9975 Summers Ridge Road, San Diego, California 92121, United States of America;

| • |  | you may send a subsequent properly completed proxy card in accordance with the instructions in this joint proxy statement/prospectus;

| • |  | you may grant a subsequent proxy by telephone or through the Internet in accordance with the instructions in this joint proxy statement/prospectus; or

| • |  | you may attend the Quidel Stockholders’ Meeting and either vote or revoke your proxy in writing. Your attendance at the Quidel Stockholders’ Meeting will not automatically revoke your proxy unless you vote again at the Quidel Stockholders’ Meeting or specifically request in writing that your prior proxy be revoked. Virtual attendance by stockholders of record at the Quidel Stockholders’ Meeting will constitute presence in person for the purpose of determining the presence of a quorum for the transaction of business at the Quidel Stockholders’ Meeting.

Ortho Shareholder of Record: If you are an Ortho shareholder of record, you may revoke your proxy or change your vote for either meeting in any one of the following ways:

| • |  | you may send a subsequent properly completed proxy card in accordance with the instructions in this joint proxy statement/prospectus;

| • |  | you may grant a subsequent proxy through the Internet in accordance with the instructions in this joint proxy statement/prospectus;

| • |  | you may send a written notice that you are revoking your proxy to Ortho Clinical Diagnostics Proxy, Attention: [●]; or

| • |  | you may attend the Ortho Court Meeting and/or the Ortho General Meeting and vote via the Virtual Meeting Platform. Your attendance at either meeting will not automatically revoke your proxy.

Q: | What should I do if I receive more than one set of voting materials for a particular meeting?

A: | You may receive more than one set of voting materials for the same meeting, including multiple copies of this joint proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, a holder of Quidel Shares or Ortho Shares who holds shares in more than one brokerage account would receive a separate voting instruction card for each brokerage account in which such holder holds shares. Additionally, a holder of record of shares whose shares are registered in more than one name would receive more than one proxy card.

In order to ensure that all of your shares are voted at the Quidel Stockholders’ Meeting, the Ortho Court Meeting or the Ortho General Meeting (as applicable), please complete, sign, date and return each proxy card and voting instruction card that you receive.

Q: | Are there risks associated with the Combinations that I should consider in deciding how to vote?

A: | Yes. You should carefully read the detailed description of the risks associated with the Combinations and Topco’s operations following the Combinations described in the section entitled “Risk Factors” of this joint proxy statement/prospectus. You also should read and carefully consider the risk factors associated with the businesses of both Quidel and Ortho that are included in, or contained in the documents that are incorporated by reference into, this joint proxy statement/prospectus because these risks will relate to the business of Topco following the completion of the Combinations.

Q: | Who will count the votes at each meeting?

A: | At the Quidel Stockholders’ Meeting, American Election Services LLC will serve as inspector of elections and will count the votes. At the Ortho Shareholder Meetings, [●] will serve as registrar and will count the votes.

10

Q: | Where can I find the voting results of the Quidel Stockholders’ Meeting, the Ortho Court Meeting and the Ortho General Meeting?

A: | Regarding the Quidel Stockholders’ Meeting and the Ortho Shareholder Meetings, the preliminary voting results will be announced at each meeting. In addition, within four Business Days following certification of the final voting results, each of Quidel and Ortho intends to file the final voting results with the SEC on a Current Report on Form 8-K.

Q: | What is “householding”?

A: | The SEC has adopted rules that permit companies and intermediaries (such as brokers or banks) to satisfy the delivery requirements for proxy statements with respect to two or more security holders sharing the same address by delivering a single notice or proxy statement addressed to those security holders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for security holders and cost savings for companies.

Several brokers and banks with accountholders who are Quidel stockholders or Ortho shareholders will be “householding” Quidel’s or Ortho’s proxy materials. As indicated in the notices provided by these brokers to Quidel stockholders and Ortho shareholders, a single proxy statement will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from an affected stockholder. Once you have received notice from your broker that it will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If at any time you no longer wish to participate in “householding” and you prefer to receive a separate proxy statement, if you are a Quidel stockholder, please notify your broker or contact Quidel’s proxy solicitor, Innisfree M&A Incorporated, at (877) 750-0537, or if you are an Ortho shareholder, please notify your broker or Ortho’s proxy solicitor, MacKenzie Partners, Inc., toll-free at 1-800-322-2885. Quidel stockholders or Ortho shareholders who currently receive multiple copies of this joint proxy statement/prospectus at their address and would like to request “householding” of their communications should contact their broker or nominee.

See the section entitled “Householding of Proxy Materials” of this joint proxy statement/prospectus for additional information.

Ortho is a public limited company organized under the laws of England and Wales. On February 1, 2021, Ortho closed the initial public offering of its ordinary shares, and Ortho Shares began trading on Nasdaq under the symbol “OCDX” on January 28, 2021. Prior to September 2021, Ortho was a “controlled company” within the meaning of the corporate governance standards of Nasdaq. Under these rules, Ortho was not subject to a number of corporate governance rules relating to the composition of its board of directors and certain committees. Following the sale of Ortho Shares by the Carlyle Stockholder in September 2021, Ortho no longer qualifies as a “controlled company.” As of March 4, 2022, the Carlyle Stockholder beneficially owned approximately 49.7% of the outstanding Ortho Shares and had the ability to nominate up to eight directors to the Ortho Board pursuant to the terms of Ortho’s articles of association. Following the closing of the Combinations, we expect that the Carlyle Stockholder will beneficially own approximately 18.7% of the outstanding Topco Shares. Pursuant to the Principal Stockholders Agreement, the Carlyle Stockholder will have the right to appoint two directors to the Topco Board while it holds at least 12% of the outstanding Topco Shares, one director while it holds at least 5% but less than 12% of the outstanding Topco shares and no directors once it holds less than 5% of the outstanding Topco Shares.

Concurrently with execution of the BCA, the Carlyle Stockholder delivered to Ortho and Quidel a deed of irrevocable undertaking to vote or procure votes in favor of the Ortho Scheme at the Ortho Court Meeting and the resolutions to be

13

proposed at the Ortho General Meeting in respect of the 118,106,000 Ortho Shares beneficially owned by the Carlyle Stockholder, which represents approximately 49.79% of the Ortho Shares. Approval of the Ortho Scheme requires, assuming all of the Ortho Shares continue to be held directly by Cede & Co., as depositary nominee of The Depositary Trust Company, and GTU Ops, Inc., as nominee of Computershare, a vote in favor of the Ortho Scheme by the majority of votes cast through each of these nominees. For more information, see “Stockholders Agreement / Deed of Irrevocable Undertaking.”

The principal executive offices of Ortho are located at 1001 Route 202, Raritan, New Jersey 08869, United States of America, and its telephone number at that address is (908) 218-8000.

As of January 2, 2022, Ortho had total indebtedness of approximately $2.0 billion, which is expected to remain outstanding following the closing of the Combinations. For more information, see “Risk Factors—Risks Relating to Ortho’s Business—Risks Relating to Ortho’s Indebtedness.” In addition, Ortho has assumed certain underfunded and unfunded net pension liabilities of approximately $40.0 million in relation to defined benefit pension plans, which will need to be satisfied as they mature. Ortho also has a history of net losses and for the fiscal years ended January 2, 2022, January 3, 2021 and December 29, 2019, Ortho recorded net losses of approximately $54.3 million, $211.9 million and $156.9 million, respectively.

The Combinations and the Business Combination Agreement

The terms and conditions of the Combinations are contained in the BCA, a copy of which is attached as Annex A to this joint proxy statement/prospectus. Quidel and Ortho encourage you to read the entire BCA carefully because it is the principal document governing the Combinations. For more information on the Combinations, see the section entitled “The Combinations” of this joint proxy statement/prospectus.

Structure and Effective Times

The Combinations will be implemented in two main steps. First, pursuant to the Ortho Scheme, each Ortho Share will be acquired by a nominee of Topco (or, if such nominee holds the Ortho Shares today, transferred within the nominee), such that Ortho will become a wholly owned subsidiary of Topco. Second, immediately following the consummation of the Ortho Scheme, U.S. Merger Sub will merge with and into Quidel with Quidel surviving the merger as a wholly owned subsidiary of Topco. The Combinations will become effective sequentially (i) with the Ortho Scheme Order becoming effective on the Scheme Effective Date and at the time the Ortho Scheme Order is duly delivered to the Registrar, such time being the “Ortho Effective Time,” and (ii) with the certificate of merger relating to the Quidel Merger (the “Quidel Certificate of Merger”) becoming effective on the Scheme Effective Date immediately following the Ortho Effective Time (or such subsequent time as Ortho and Quidel shall agree and as shall be specified in the Quidel Certificate of Merger, and in no event prior to the Ortho Effective Time), such time being the “Quidel Effective Time.”

As a result of the Combinations, Ortho and Quidel will each become wholly owned subsidiaries of Topco, and Ortho shareholders and Quidel stockholders will become Topco stockholders. If the Combinations are completed, Ortho shareholders are expected to own approximately 38% of Topco and Quidel stockholders are expected to own approximately 62% of Topco, on a fully diluted basis, based on the respective capitalizations of Ortho and Quidel as of the date the parties entered into the BCA.

The closing of the Combinations will take place on the Scheme Effective Date (the “Closing Date”). Subject to the terms and conditions set forth in the BCA, on the Closing Date, and as soon as practicable after the Ortho Scheme Order is duly filed with the Registrar, Quidel will file the Quidel Certificate of Merger with the Secretary of State of the State of Delaware in accordance with the relevant provisions of the Delaware General Corporation Law (the “DGCL”) and shall make all other filings or recordings required under the DGCL.

Merger Consideration

Ortho Shares Consideration

The BCA provides that, at the Ortho Effective Time, each Ortho Share, other than Ortho Shares held by Ortho in treasury, will be acquired by a nominee (or, if such nominee holds the Ortho Shares today, transferred within the nominee) on behalf and for the benefit of Topco in exchange for 0.1055 Topco Shares and $7.14 in cash.

Quidel Shares Consideration

The BCA provides that, at the Quidel Effective Time, each Quidel Share, other than Quidel Shares held by Quidel, Ortho or U.S. Merger Sub, will be converted into the right to receive one Topco Share.

Treatment of Ortho Equity Awards

Stock Options

At the Ortho Effective Time, each Ortho Stock Option, whether vested or unvested, that is outstanding immediately prior to the Ortho Effective Time will cease to represent an option to acquire Ortho Shares and will be converted into

15

(a) an option to purchase Topco Shares (each, a “Topco Stock Option”) on the same terms and conditions as were applicable to such Ortho Stock Option immediately prior to the Ortho Effective Time, except as adjusted by the BCA, (b) with respect to the portion of such Ortho Stock Option that is vested as of the Ortho Effective Time, the right to receive payment, in cash, equal to the cash consideration payable in respect of the Ortho Shares subject to the vested portion of such Ortho Stock Option and (c) with respect to the portion of such Ortho Stock Option that is not vested as of the Ortho Effective Time, the right to receive payment, in cash, equal to the cash consideration payable in respect of the Ortho Shares subject to the unvested portion of such Ortho Stock Option when it vests in accordance with its terms. See the section of this joint proxy statement/prospectus entitled “The Business Combination Agreement—Treatment of Ortho Equity Awards” for further details on the treatment of Ortho Stock Options.

Restricted Stock Units

At the Ortho Effective Time, each Ortho Equity Right that is outstanding immediately prior to the Ortho Effective Time will cease to relate to or represent a right to receive Ortho Shares and will be converted into a Topco Equity Right of the same type and on the same terms and conditions as were applicable to the corresponding Ortho Equity Right immediately prior to the Ortho Effective Time. Upon the subsequent vesting of any portion of such Ortho Equity Right, such portion of the Ortho Equity Right shall also be entitled to a right to receive payment, in cash, equal to the cash consideration in respect of the Ortho Shares subject to the unvested portion of the Ortho Equity Right when it vests in accordance with its terms. See the section of this joint proxy statement/prospectus entitled “The Business Combination Agreement—Treatment of Ortho Equity Awards” for further details on the treatment of Ortho Equity Rights.

Treatment of Quidel Equity Awards

Stock Options

At the Quidel Effective Time, each outstanding option to purchase Quidel Shares (a “Quidel Stock Option”) granted under the Quidel employee and director stock plans (each, a “Quidel Stock Plan” and together, the “Quidel Stock Plans”), whether vested or unvested, will cease to represent an option to acquire Quidel Shares and will automatically, without any action on the part of the holder thereof, be converted into a Topco Stock Option on the same terms and conditions (including applicable vesting conditions) applicable to such Quidel Stock Option under the applicable Quidel Stock Plan and award agreement in effect immediately prior to the Quidel Effective Time, except as adjusted by the BCA. See the section of this joint proxy statement/prospectus entitled “The Business Combination Agreement—Treatment of Quidel Equity Awards” for further details on the treatment of Quidel Stock Options.

Restricted Stock Units

At the Quidel Effective Time, each outstanding Quidel restricted stock unit (a “Quidel RSU”) granted under the Quidel Stock Plans will automatically, without any action on the part of the holder thereof, be converted into a restricted stock unit of Topco (a “Topco RSU”) on the same terms and conditions (including applicable vesting conditions) applicable to such Quidel RSU under the applicable Quidel Stock Plan and award agreement in effect immediately prior to the Quidel Effective Time. See the section of this joint proxy statement/prospectus entitled “The Business Combination Agreement—Treatment of Quidel Equity Awards” for further details on the treatment of Quidel RSUs.

Performance Restricted Stock Units

At the Quidel Effective Time, each outstanding Quidel performance restricted stock unit (a “Quidel PSU”) granted under a Quidel Stock Plan will automatically, without any action on the part of the holder thereof, be converted into a performance restricted stock unit of Topco (a “Topco PSU”) on the same terms and conditions (including applicable vesting conditions) applicable to such Quidel PSU under the applicable Quidel Stock Plan and award agreement in effect immediately prior to the Quidel Effective Time. See the section of this joint proxy statement/prospectus entitled “The Business Combination Agreement—Treatment of Quidel Equity Awards” for further details on the treatment of Quidel PSUs.

Opinion of J.P. Morgan Securities LLC as Financial Advisor to Ortho

Pursuant to an engagement letter, Ortho retained J.P. Morgan as its financial advisor in connection with the Combinations. At the meeting of the Ortho board of directors on December 22, 2021, J.P. Morgan rendered its oral opinion to the Ortho board of directors that, as of such date and based upon and subject to the assumptions made, procedures followed, matters considered and limitations on the review undertaken by J.P. Morgan in preparing its opinion, the Ortho Scheme Consideration to be paid to the holders of Ortho Shares was fair, from a financial point of view, to such holders. J.P. Morgan confirmed its December 22, 2021 oral opinion by delivering its written opinion, dated as of December 23, 2021, to the Ortho board of directors that, as of such date, the Ortho Scheme Consideration was fair, from a financial point of view, to the holders of Ortho Shares.

The full text of the written opinion of J.P. Morgan, dated December 23, 2021, which sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the review undertaken by J.P. Morgan in preparing its opinion, is attached as Annex E to this joint proxy statement/prospectus and is incorporated herein by reference. The summary of the opinion of J.P. Morgan set forth in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of such opinion.

J.P. Morgan expressed no opinion as to the fairness of the Ortho Scheme Consideration to the holders of any other class of securities, creditors or other constituencies of Ortho

Material U.S. Tax Considerations

Material U.S. Federal Income Tax Considerations to U.S. Holders of Ortho Shares of the Ortho Scheme

The exchange of Ortho Shares for Topco Shares and cash pursuant to the Ortho Scheme, taken together with the Quidel Merger, will qualify as a transaction described in Section 351 of the Code. As a result, subject to the limitations and qualifications described in the section entitled “Material U.S. Federal Income Tax Considerations” of this joint proxy statement/prospectus, gain (but not loss) will be recognized on the exchange of Ortho Shares for a combination of cash and Topco Shares pursuant to the Ortho Scheme in an amount equal to the lesser of: (a) the excess of (i) the sum of the fair market value of the Topco Shares and the amount of cash received by such U.S. Holder over (ii) such U.S. Holder’s tax basis in its Ortho Shares, and (b) the amount of cash received by such U.S. Holder pursuant to the Ortho Scheme. The treatment of the cash received in lieu of fractional Topco Shares is discussed separately in the section entitled “Material U.S. Federal Income Tax Considerations” of this joint proxy statement/prospectus.

18

Material U.S. Federal Income Tax Considerations to U.S. Holders of Quidel Shares of the Quidel Merger

The exchange of Quidel Shares for Topco Shares pursuant to the Quidel Merger, taken together with the Ortho Scheme, will qualify as a transaction described in Section 351 of the Code. As a result, subject to the limitations and qualifications described in the section entitled “Material U.S. Federal Income Tax Considerations” of this joint proxy statement/prospectus, no gain or loss is expected to be recognized by the U.S. Holders of Quidel Shares as a result of the Quidel Merger.

Material U.S. Federal Income Tax Considerations to Non-U.S. Holders of Owning and Disposing of Topco Shares Received in the Combinations

Distributions to Non-U.S. Holders with respect to Topco Shares will generally be subject to U.S. federal withholding tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) to the extent such distributions are dividends for U.S. federal income tax purposes and are not effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States. Dividends that are effectively with the Non-U.S. Holder’s conduct of a trade or business within the United States will generally be subject to U.S. federal income tax on a net income basis at the regular graduated U.S. federal income tax rates and, for Non-U.S. Holders that are corporations, may be subject to an additional branch profits tax at a rate of 30% (or a lower rate specified by an applicable income tax treaty).

Subject to the exceptions and qualifications described in “Material U.S. Federal Income Tax Considerations,” a Non-U.S. Holder generally will not be subject to U.S. federal income tax on any gain realized upon the sale or other disposition of Topco Shares.

Please carefully review the information set forth in the section entitled “Material U.S. Federal Income Tax Considerations” of this joint proxy statement/prospectus for a discussion of certain U.S. federal income tax considerations relating to the Combinations. Please consult your tax advisors as to the specific tax consequences to you of the Combinations.

Material UK Tax Considerations

Subject to the comments below in relation to Section 137 of the UK Taxation of Chargeable Gains Act 1992 (the “TCGA”), the receipt of Topco Shares by an Ortho shareholder in respect of, and in proportion to, such shareholder’s Ortho Shares pursuant to the Combinations may potentially be treated as a scheme of reconstruction for the purposes of UK capital gains tax or corporation tax on chargeable gain (collectively, “CGT”). On that basis, an Ortho shareholder would not be treated as making a disposal of their Ortho Shares and, therefore, no liability to CGT would arise in respect of the receipt of Topco Shares by an Ortho shareholder pursuant to the Combinations. For the purposes of CGT, the Topco Shares received by an Ortho shareholder would be treated as the same asset, acquired at the same time and for the same amount, as the Ortho Shares in respect of which they are issued.

If the “rollover” treatment described above is not available (and no assurance is or can be given that such treatment will be available), an Ortho shareholder would be treated as having made a full disposal of their Ortho Shares and may, depending on such shareholder’s personal circumstances, be liable to pay CGT.

Under Section 137 of the TCGA, any Ortho shareholder who holds (when his, her or its relevant holding is aggregated with that of persons connected with him, her or it) more than 5% of, or of any class of, shares in or debentures of Ortho will not in any event receive the possible “rollover” treatment described above if the relevant transaction has not been effected for bona fide commercial reasons or if it forms part of a scheme or arrangement of which the main purpose, or one of the main purposes, is the avoidance of liability to CGT or UK corporation tax. It is possible to apply for statutory clearance from HM Revenue & Customs (“HMRC”) under Section 138 of the TCGA confirming that this anti-avoidance provision does not apply. No application for clearance has been made to HMRC under Section 138 of the TCGA in respect of the receipt of Topco Shares pursuant to the Combinations. For the avoidance of doubt, please note that any Ortho shareholder who holds (when their relevant holding is aggregated with that of persons connected with them) 5% or less of, or of any class of, shares in or debentures of Ortho would not have to satisfy this anti-avoidance provision.

19

For a further discussion of the material UK tax considerations relating to the Combinations, see the section entitled “Material UK Tax Considerations” of this joint proxy statement/prospectus. Please consult your tax advisors as to the specific tax consequences to you of the Combinations.

Delisting and Deregistration of Ortho Shares and Quidel Shares

Promptly after the Ortho Effective Time, the Ortho Shares will be delisted from Nasdaq and deregistered under the Exchange Act, and promptly after the Quidel Effective Time, the Quidel Shares will be delisted from Nasdaq and deregistered under the Exchange Act. Topco will be the successor to Quidel for purposes of Topco’s Nasdaq listing.

Litigation Relating to the Combinations

Since the announcement of the Combinations, one putative complaint has been filed by and purportedly on behalf of an alleged Ortho shareholder: Rydberg v. Ortho Clinical Diagnostics Holdings plc, et al., No. 1:22-cv-01334 filed March 10, 2022 in the United States District Court for the Eastern District of New York (the “Action”).

The Action names as defendants Ortho and the members of Ortho’s Board of Directors. The Action alleges, among other things, that the joint proxy statement/prospectus omits certain information regarding projections of Ortho, Quidel and Topco, the analysis performed by the financial advisor of Ortho, and potential conflicts of interest involving a financial advisor and Ortho’s officers and directors. The Action seeks, among other things, injunctive relief to prevent the Combinations from closing, damages if the Combinations close, and attorneys’ fees. Ortho believes these claims are entirely without merit and that the joint proxy statement/prospectus does not omit any material information about the Combinations.

Interests of Quidel Officers and Directors in the Combinations

Quidel’s executive officers and directors have interests in the Combinations that are different from, or in addition to, the interests of Quidel stockholders generally. These interests may include, but are not limited to:

| • |  | the treatment in the Combinations of equity awards held by Quidel directors and executive officers;

| • |  | the continued engagement and/or employment, as applicable, of certain executive officers of Quidel;

| • |  | the continued positions of certain directors of Quidel as directors on the board of directors of Topco; and

| • |  | severance payments payable under existing employment and severance arrangements or arrangements that may be entered into in connection with the Combinations.

The Quidel board of directors was aware of these potentially differing interests and considered them, among other matters, in reaching its decision to adopt the BCA, approve the Combinations and to recommend that you vote in favor of the Merger Proposal, the Adjournment Proposal, the Election of Directors Proposal, the Independent Registered Public Accounting Firm Proposal, the Equity Incentive Plan Proposal and the ESPP Proposal and the approval (on a non-binding, advisory basis) for the Advisory Merger Compensation Proposal and the Advisory Executive Compensation Proposal.

For further information with respect to arrangements between Quidel and its executive officers and directors, as well as arrangements for Topco director nominees, see the section entitled “Interests of Certain Persons in the Combinations (Quidel)” of this joint proxy statement/prospectus.

See the sections entitled “The Combinations—Background of the Combinations” and “The Combinations—Quidel Reasons for the Combinations and Recommendation of the Quidel Board of Directors” of this joint proxy statement/prospectus. Quidel stockholders should take these interests into account in deciding whether to vote “FOR” the Merger Proposal.

20

Interests of Ortho Officers and Directors in the Combinations

Ortho’s executive officers and directors have interests in the Ortho Scheme that are different from, or in addition to, the interests of Ortho shareholders generally. These interests may include, but are not limited to:

| • |  | the continued engagement and/or employment, as applicable, of certain board members and executive officers of Ortho;

| • |  | the continued positions of certain directors of Ortho as directors on the board of directors of Topco;

| • |  | the treatment in the Combinations of equity awards and stock options held by Ortho directors and executive officers;

| • |  | retention bonus awards, 40% of which will be payable at the closing of the Combinations and the remaining 60% of which will be payable on the first anniversary of the closing of the Combinations;

| • |  | transaction bonuses payable upon the closing of the Combinations; and

| • |  | severance payments payable under existing employment and severance arrangements or arrangements that may be entered into in connection with the Combinations.

The Ortho board of directors was aware of these potentially differing interests and considered them, among other matters, in reaching its decision to adopt the BCA, approve the Combinations and to recommend that you vote in favor of all proposals to be approved at the Ortho Shareholder Meetings.

For further information with respect to arrangements between Ortho and its executive officers and directors, as well as arrangements for Topco director nominees, see the section entitled “Interests of Certain Persons in the Combinations (Ortho)” of this joint proxy statement/prospectus.

See the sections entitled “The Combinations—Background of the Combinations” and “The Combinations—Ortho Reasons for the Combinations and Recommendation of the Ortho Board of Directors” of this joint proxy statement/prospectus. Ortho shareholders should take these interests into account in deciding whether to vote “FOR” the proposals to be approved at the Ortho Shareholder Meetings.

Indemnification and Insurance

Pursuant to the terms of the BCA, Ortho’s, Quidel’s and any of their subsidiaries’ directors, officers and employees will be entitled to certain ongoing indemnification and insurance coverage from Topco. For additional information, see the section entitled “The Business Combination Agreement—Indemnification and Insurance” of this joint proxy statement/prospectus.

Board of Directors and Management of Topco Following Completion of the Combinations

Effective as of the Ortho Effective Time, the Topco board of directors will consist of 12 members, comprised of: (i) eight directors designated by Quidel prior to closing, one of whom will be the Chief Executive Officer of Quidel immediately prior to the Quidel Effective Time, and at least four of whom will qualify as an “independent director” under applicable rules of Nasdaq, and (ii) four directors designated by Ortho prior to closing, at least two of whom will qualify as an “independent director” under the applicable rules of Nasdaq. Each of the members of the Topco board of directors designated by Ortho shall be reasonably acceptable to the nominating and corporate governance committee of the current Quidel board of directors.

As of the Ortho Effective Time, the Topco board of directors will form the following board committees: the audit committee (the “Audit Committee”), the compensation committee (the “Compensation Committee”) and the nominating and corporate governance committee (the “Nominating and Governance Committee”). The Audit Committee, the Compensation Committee and the Nominating and Governance Committee will each be chaired by a member of the Topco board of directors designated by Quidel. The Audit Committee, the Compensation Committee and the Nominating and Governance Committee will each consist of one member of the Topco board of directors designated by Ortho and not less than two additional members of the Topco board of directors designated by Quidel, in

21

each case, subject to applicable legal and regulatory requirements, and, in the case of the Ortho designees, such designees must be reasonably acceptable to the Topco board of directors. The charters for the Audit Committee, the Compensation Committee and the Nominating and Governance Committee will each be substantially similar to the charters for the respective committees of the Quidel board of directors that were in effect as of the date of the BCA.

Pursuant to the terms of the BCA, at the Ortho Effective Time, Douglas Bryant, current President and Chief Executive Officer of Quidel, will serve as Chair and Chief Executive Officer of Topco. Joseph M. Busky, current Chief Financial Officer of Ortho, will serve as Chief Financial Officer of Topco. Robert J. Bujarski, current Chief Operating Officer of Quidel, will serve as President and Chief Operating Officer of Topco. Michael S. Iskra, current Executive Vice President of Commercial Excellence & Strategy at Ortho, will serve as Chief Commercial Officer of Topco.

24

| • |  | by Quidel, at any time prior to the receipt of the Ortho Requisite Vote, if the Ortho board of directors has effected an Ortho Change in Recommendation (whether or not in compliance with the applicable provisions of the BCA);

| • |  | by Quidel, at any time prior to the Ortho Effective Time, if Ortho breaches or fails to perform any of its covenants or agreements contained in the BCA, or if any of the representations or warranties of Ortho contained therein fails to be true and correct, which breach or failure (a) would give rise to the failure of the conditions to Quidel’s obligation to close and (b) is not reasonably capable of being cured by Ortho by the Termination Date or is not cured by Ortho within 45 days after receiving written notice from Quidel, unless Quidel’s failure to perform any material covenant or obligation under the BCA has been the primary cause of, or primarily resulted in, the failure of any such closing condition to be satisfied on or before the Termination Date;

| • |  | by Quidel, at any time prior to the receipt of the Quidel Requisite Vote, if the Quidel board of directors has effected a Quidel Change in Recommendation in compliance with the BCA in response to a Quidel All Cash Superior Proposal and in order for Quidel to enter into a merger agreement, acquisition agreement or other similar agreement that the Quidel board of directors has authorized and directed Quidel to execute with respect to such Quidel All Cash Superior Proposal; provided, however, that the BCA may not be so terminated unless (a) prior to or simultaneously with such termination the Quidel Termination Payment (as defined below) has been made in full to Ortho, and (b) simultaneously or promptly following such termination Quidel enters into such agreement;

Expenses and Termination Fees

All costs and expenses incurred in connection with the BCA and the Combinations and the other transactions contemplated by the BCA generally are to be paid by the party incurring such costs and expenses, but Quidel and Ortho will share equally all expenses associated with antitrust filings, the Nasdaq listing application and the filing, printing and mailing of this joint proxy statement/prospectus, the Registration Statement and other disclosure documents required in connection with the Combinations.

Quidel must pay Ortho a termination fee of approximately $207.8 million (the “Quidel Termination Payment”) if:

| • |  | the BCA is terminated by Ortho, as a result of a Quidel Change in Recommendation;

25

| • |  | the BCA is terminated by either Quidel or Ortho if (i) the Combinations are not consummated by the Termination Date or (ii) the Quidel Requisite Vote has not been obtained at the Quidel Stockholders’ Meeting and, at the time of such termination, Ortho had a right to terminate as a result of a Quidel Change in Recommendation;

| • |  | (a) an Acquisition Proposal for Quidel shall have been publicly announced or made publicly known or otherwise communicated or made known to Quidel management or the Quidel board of directors (or any third party shall have publicly announced, communicated or made known a bona fide intention, whether or not conditional, to make a proposal with respect to an Acquisition Proposal) and not withdrawn prior to termination or such vote to adopt the BCA, as applicable, at any time after the date of the BCA and (b) the BCA is subsequently terminated by Ortho as a result of Quidel’s breach of the BCA or is terminated by either Quidel or Ortho because (i) the Combinations are not consummated by the Termination Date or (ii) the Quidel Requisite Vote has not been obtained at the Quidel Stockholders’ Meeting and, at the time of such termination, Ortho had a right to terminate the BCA as a result of a failure by Quidel to perform any of its covenants or agreements contained in the BCA;

| • |  | the BCA is terminated by Quidel in connection with a Quidel All Cash Superior Proposal, subject to certain additional conditions; or

| • |  | (a) an Acquisition Proposal for Quidel has been publicly announced or made publicly known or otherwise communicated or made known to Quidel management or the Quidel board of directors (or any third party shall have publicly announced, communicated or made known a bona fide intention, whether or not conditional, to make a proposal with respect to an Acquisition Proposal) and not withdrawn prior to termination or such vote to adopt the BCA, as applicable, at any time after the date of the BCA, (b) the BCA is subsequently terminated by Quidel or Ortho because (i) the Combinations are not consummated by the Termination Date or (ii) the Quidel Requisite Vote has not been obtained at the Quidel Stockholders’ Meeting, and (c) within nine months of such termination, Quidel or any of its subsidiaries executes an acquisition agreement with respect to, or consummates, or approves or recommends to the Quidel stockholders to accept, any Acquisition Proposal (provided that, for purposes of this clause (c), the term “Acquisition Proposal” is defined as in the section entitled “The Business Combination Agreement—Acquisition Proposals” of this joint proxy statement/prospectus, except that each reference to “15% or more” in the definition of “Acquisition Proposal” and “Major Subsidiary” shall be deemed to be a reference to “50% or more”).

In the event that the BCA is terminated because the Quidel Requisite Vote has not been obtained at the Quidel Stockholders’ Meeting, and the Quidel Termination Payment is not otherwise payable, then Quidel shall pay, or cause to be paid, to Ortho by way of reimbursement its reasonable documented out-of-pocket costs, fees and expenses incurred in connection with its investigation, consideration, documentation, diligence and negotiations of the BCA and the transactions contemplated thereby, including all reasonable fees and expenses of Ortho’s and its subsidiaries’ respective representatives and financing sources.

In the event the Quidel Termination Payment is payable by Quidel to Ortho after the time Quidel pays any expense reimbursement to Ortho in accordance with the terms of the BCA, the amount of the Quidel Termination Payment payable by Quidel to Ortho will be reduced by the amount of such expense reimbursement actually paid to Ortho.

Ortho must pay Quidel a termination fee of approximately $46.9 million (the “Ortho Termination Payment”) if:

| • |  | the BCA is terminated by Quidel, as a result of an Ortho Change in Recommendation;

| • |  | the BCA is terminated by either Quidel or Ortho if (i) the Combinations are not consummated by the Termination Date or (ii) the Ortho Requisite Vote has not been obtained at the Ortho Shareholder Meetings or the Ortho Scheme is not sanctioned and the Ortho Scheme Order is not issued by the English Court and, at the time of such termination, Quidel had a right to terminate as a result of an Ortho Change in Recommendation;

| • |  | (a) an Acquisition Proposal for Ortho shall have been publicly announced or made publicly known or otherwise communicated or made known to Ortho management or the Ortho board of directors (or any third party shall have publicly announced, communicated or made known a bona fide intention, whether or not

26

| conditional, to make a proposal with respect to an Acquisition Proposal) and not withdrawn prior to termination or such vote to adopt the BCA, as applicable, at any time after the date of the BCA and (b) the BCA is subsequently terminated by Quidel as a result of Ortho’s breach of the BCA or is terminated by either Quidel or Ortho because (i) the Combinations are not consummated by the Termination Date or (ii) the Ortho Requisite Vote has not been obtained at the Ortho Shareholder Meetings or the Ortho Scheme is not sanctioned and the Ortho Scheme Order is not issued by the English Court and, at the time of such termination, Quidel had a right to terminate the BCA as a result of a failure by Ortho to perform any of its covenants or agreements contained in the BCA;

| • |  | the BCA is terminated by Ortho in connection with an Ortho All Cash Superior Proposal, subject to certain additional conditions; or

| • |  | (a) an Acquisition Proposal for Ortho has been publicly announced or made publicly known or otherwise communicated or made known to Ortho management or the Ortho board of directors (or any third party shall have publicly announced, communicated or made known a bona fide intention, whether or not conditional, to make a proposal with respect to an Acquisition Proposal) and not withdrawn prior to termination or such vote to adopt the BCA, as applicable, at any time after the date of the BCA, (b) the BCA is subsequently terminated by Quidel or Ortho because (i) the Combinations are not consummated by the Termination Date or (ii) the Ortho Requisite Vote has not been obtained at the Ortho Shareholder Meetings or the Ortho Scheme is not sanctioned and the Ortho Scheme Order is not issued by the English Court, and (c) within nine months of such termination, Ortho or any of its subsidiaries executes an acquisition agreement with respect to, or consummates, or approves or recommends to the Ortho shareholders to accept, any Acquisition Proposal (provided that, for purposes of this clause (c), the term “Acquisition Proposal” is defined as in the section entitled “The Business Combination Agreement—Acquisition Proposals” of this joint proxy statement/prospectus, except that each reference to “15% or more” in the definition of “Acquisition Proposal” and “Major Subsidiary” shall be deemed to be a reference to “50% or more”).

In the event that the BCA is terminated because the Ortho Requisite Vote has not been obtained at the Ortho Shareholder Meetings or the Ortho Scheme is not sanctioned and the Ortho Scheme Order is not issued by the English Court, and the Ortho Termination Payment is not otherwise payable, then Ortho shall pay, or cause to be paid, to Quidel by way of reimbursement its reasonable documented out-of-pocket costs, fees and expenses incurred in connection with its investigation, consideration, documentation, diligence and negotiations of the BCA and the transactions contemplated thereby, including all reasonable fees and expenses of Quidel’s and its subsidiaries’ respective representatives and financing sources.

In the event the Ortho Termination Payment is payable by Ortho to Quidel after the time Ortho pays any expense reimbursement to Quidel in accordance with the terms of the BCA, the amount of the Ortho Termination Payment payable by Ortho to Quidel will be reduced by the amount of such expense reimbursement actually paid to Quidel.

Regulatory Matters

Ortho and Quidel have agreed to use their reasonable best efforts to obtain all regulatory approvals required to complete the transactions contemplated by the BCA. These approvals include clearance under the HSR Act, and other merger control and foreign investment laws and regulations. Ortho and Quidel have completed, or will complete, the filing of applications and notifications to obtain the required regulatory approvals.

For more information, see the section entitled “The Combinations—Regulatory Matters” of this joint proxy statement/prospectus.

Security Ownership of Quidel Directors and Executive Officers

As of close of business on March 4, 2022, directors and executive officers of Quidel and their affiliates were entitled to vote 1,154,623 Quidel Shares, or approximately 2.7% of the Quidel Shares outstanding and entitled to vote on that date.

For more information, see the section entitled “Security Ownership of Certain Quidel Beneficial Owners and Management” of this joint proxy statement/prospectus.

27

Security Ownership of Ortho Directors and Executive Officers

As of close of business on March 4, 2022, directors and executive officers of Ortho and their affiliates were entitled to vote 3,187,125 Ortho Shares, or approximately 1.3% of the Ortho Shares outstanding and entitled to vote on that date.

For more information, see the section entitled “Security Ownership of Certain Ortho Beneficial Owners and Management” of this joint proxy statement/prospectus.

No Appraisal Rights for Quidel Stockholders

Appraisal rights are statutory rights under the DGCL that enable stockholders who object to certain extraordinary transactions to demand that the corporation pay such stockholders the fair value of their shares instead of receiving the consideration offered to stockholders in connection with the extraordinary transaction. However, appraisal rights are not available in all circumstances. Appraisal rights are not available to Quidel stockholders in connection with the Combinations.

No Delaware Appraisal Rights for Ortho Shareholders

As shareholders in a UK public limited company, Ortho shareholders do not have appraisal rights similar to the statutory rights under the DGCL that enable shareholders who object to certain extraordinary transactions to demand that the corporation pay such shareholders the fair value of their shares instead of receiving the consideration offered to shareholders in connection with the extraordinary transaction.

Listing of Topco Shares on Stock Exchanges

Topco Shares currently are not traded or quoted on a stock exchange or quotation system. The parties expect that, following completion of the Combinations, Topco Shares will be listed for trading on Nasdaq, and it is a condition to the parties’ obligations to effect the Combinations that the Topco Shares be authorized for listing on Nasdaq, subject to official notice of issuance.

Accounting Treatment

Topco will account for the Combinations using the acquisition method of accounting in accordance with ASC Topic 805. For further information, see the section entitled “Unaudited Pro Forma Combined Financial Information” of this joint proxy statement/prospectus.

Comparison of Rights of Stockholders of Quidel, Ortho and Topco

Quidel and Topco are organized under the laws of the State of Delaware. Ortho is organized under the laws of England and Wales. If the Combinations are consummated, the Quidel stockholders and Ortho shareholders will become stockholders of Topco. After giving effect to the Combinations, the rights of stockholders of Topco and the relative powers of the Topco board of directors will be governed by Delaware law and by the Topco Charter and Topco Bylaws. Each Topco Share will be issued pursuant to, and will carry with it the rights and obligations set forth in, the Topco Charter. As a result of differences between the respective organizational documents of Quidel, Ortho and Topco, and applicable governing law, there will be material differences between the rights of Quidel stockholders and Ortho shareholders before consummation of the Combinations and the rights of Topco stockholders after consummation of the Combinations.

For a full description of these differences, see the section entitled “Comparison of Rights of Stockholders of Quidel, Ortho and Topco” of this joint proxy statement/prospectus.

Please Read the Risk Factors

You should carefully read the detailed description of the risks associated with the Combinations and Topco’s operations following the Combinations described in the section entitled “Risk Factors” of this joint proxy statement/prospectus. You also should read and carefully consider the risk factors associated with the businesses of both Quidel and Ortho that are included in, or contained in the documents that are incorporated by reference into, this joint proxy statement/prospectus, because these risks will relate to the business of Topco following the completion of the Combinations.

RISK FACTORS

Investing in Topco Shares involves risks, some of which are related to the Combinations. You should carefully consider the risks described below, as well as the other information included in or incorporated by reference into this joint proxy statement/prospectus, including the risk factors described in Quidel’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on February 18, 2022, and the risk factors described in Ortho’s Annual Report on Form 10-K for the year ended January 2, 2022, filed with the SEC on March 8, 2022.

Risks Relating to the Combinations

Completion of the Combinations is subject to certain conditions, some of which are outside of the parties’ control, and if these conditions are not satisfied or waived, the Combinations will not be completed.

The closing of the Combinations is subject to certain conditions, including (i) Quidel stockholder approval of the Merger Proposal and related matters, (ii) Ortho shareholder approval of the Ortho Scheme, amendments to the articles of association of Ortho and certain related matters, (iii) receipt of clearance from competition and foreign investment authorities in certain areas where the companies operate, including the expiration or termination of the waiting period under the HSR Act, (iv) the absence of any law, injunction, order or other judgment prohibiting the Combinations, (v) the effectiveness of the registration statement on Form S-4 for the Topco Shares, (vi) receipt of Nasdaq listing approval for the Topco Shares, (vii) subject to certain materiality exceptions, the accuracy of each of Ortho’s and Quidel’s representations and warranties in the BCA and performance by each of Ortho and Quidel of its obligations under the BCA and (viii) the sanctioning of the Ortho Scheme by the Court and the delivery of the order of the Court of sanctioning the Ortho Scheme to the Registrar.

The requirement to satisfy each of the foregoing conditions could delay completion of the Combinations for a significant period of time or prevent them from occurring at all. Any delay in completing the Combinations could cause Topco not to realize some or all of the benefits that the parties expect Topco to achieve if the Combinations are successfully completed within the expected timeframe. Further, as a condition to approving the Combinations, governmental authorities may impose conditions, terms, obligations or restrictions on the conduct of the parties’ business after the completion of the Combinations. Under the terms of the BCA, the parties are not required to proffer or negotiate, or agree or consent to, any action (including any contractual, behavioral or conduct restriction, agreement, commitment or remedy) that would, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect (as defined in the section entitled “The Business Combination Agreement—Representations and Warranties” of this joint proxy statement/prospectus) on Topco. Notwithstanding the provisions of the BCA, if the parties were to become subject to any conditions, terms, obligations or restrictions (whether because such conditions, terms, obligations and restrictions do not rise to the specified level of materiality or because the parties consent to their imposition), it is possible that such conditions, terms, obligations or restrictions will delay completion of the Combinations or otherwise adversely affect the parties’ business, financial condition, or operations. Furthermore, governmental authorities may require that the parties divest assets or businesses as a condition to the closing of the Combinations. If the parties are required to divest assets or businesses, there can be no assurance that Quidel and Ortho will be able to negotiate such divestitures expeditiously or on favorable terms or that the governmental authorities will approve the terms of such divestitures. There can be no assurance that the conditions to the closing of the Combinations will be satisfied or, where applicable, waived or that the Combinations will be completed.

In addition, if the Ortho Effective Time shall not have occurred by September 22, 2022 (subject to certain extension rights), either Ortho or Quidel may choose not to proceed with the Combinations. Quidel and Ortho may also terminate the BCA under certain specified circumstances, including, among others, in order to enter into an agreement with respect to an all-cash proposal (A) that is determined by the Quidel board of directors, in the case of a proposal to Quidel, or (B) that is determined by the Ortho board of directors, in the case of a proposal to Ortho, to be superior to the BCA, subject to the terms and conditions of the BCA (including a requirement that the terminating party pay a termination fee to the other party in accordance with the BCA).

31

Some of the conditions to the Combinations and termination rights may be waived by Ortho or Quidel without resoliciting Ortho shareholder or Quidel stockholder approval.

Some of the conditions and termination rights set forth in the BCA may be waived by Ortho or Quidel, subject to certain limitations. If any conditions or termination rights are waived, Quidel and Ortho will evaluate whether amendment of this joint proxy statement/prospectus and resolicitation of proxies would be warranted. Subject to applicable law, if Quidel and Ortho determine that resolicitation of Quidel stockholders or Ortho shareholders is not warranted, the parties will have the discretion to complete the Combinations without seeking such additional Ortho shareholder approval or Quidel stockholder approval, as applicable. No action by the Quidel board of directors or Ortho board of directors with respect to the BCA may adversely affect the stockholders of Quidel or shareholders of Ortho, respectively, or affect the consideration to be received by the stockholders of Quidel or the shareholders of Ortho in the Combinations, unless their stockholders or shareholders, as applicable, approve such action.

Failure to complete the Combinations could negatively impact the stock price and the future business and financial results of Quidel and Ortho.

If the Combinations are not completed for any reason, including as a result of Quidel stockholders failing to adopt the BCA or Ortho shareholders failing to approve the Ortho Scheme, the ongoing businesses of Quidel and Ortho may be adversely affected and, without realizing any of the benefits of having completed the Combinations, Quidel and Ortho would be subject to a number of risks, including the following:

| • |  | Quidel may be required, under certain circumstances, to pay Ortho a termination fee of approximately $208 million or reimburse Ortho for certain fees and expenses;

| • |  | Ortho may be required, under certain circumstances, to pay Quidel a termination fee of approximately $47 million or reimburse Quidel for certain fees and expenses;

| • |  | Quidel and Ortho are subject to certain restrictions on the conduct of their businesses prior to completing the Combinations, which may adversely affect their respective abilities to execute certain of their respective business strategies going forward if the Combinations are not completed;

| • |  | Ortho and Quidel have incurred and will continue to incur significant costs and fees associated with the proposed Combinations, such as legal, accounting, financial advisor and printing fees, regardless of whether the Combinations are completed;

| • |  | Ortho and Quidel may experience negative reactions from the financial markets, including negative impacts on their stock prices;

| • |  | Ortho and Quidel may experience negative reactions from their customers, regulators and employees; and

| • |  | matters relating to the Combinations (including integration planning) will require substantial commitments of time and resources by Ortho’s and Quidel’s management, which would otherwise have been devoted to day-to-day operations and other opportunities that may have been beneficial to Ortho and Quidel as independent companies.

In addition, Ortho and Quidel could be subject to litigation related to any failure to complete the Combinations or related to any enforcement proceeding commenced against Ortho, Quidel or Topco to perform its obligations under the BCA. If the Combinations are not completed, these risks may materialize and may adversely affect Ortho’s or Quidel’s respective businesses, financial conditions, financial results and stock price.

The number of Topco Shares that Quidel stockholders will receive in the Quidel Merger and that Ortho shareholders will receive in the Ortho Scheme is based on a fixed exchange ratio that will not be adjusted to reflect changes in the market value of Quidel Shares or Ortho Shares. Further, when Ortho shareholders and Quidel stockholders vote on the transactions contemplated in the BCA, they will not know the exact value of the Topco Shares that will be issued in connection with the Combinations. The value of the Topco Shares that Quidel stockholders and Ortho shareholders receive upon completion of the Combinations could vary based on changes in the market value of Quidel Shares and Ortho Shares from the time that the Quidel stockholders and Ortho shareholders vote to adopt the BCA or approve the Ortho Scheme, as applicable.

Upon completion of the Combinations, Quidel stockholders will be entitled to receive 1.00 Topco Share for each Quidel Share that they own and Ortho shareholders will be entitled to receive 0.1055 Topco Shares for each Ortho Share that they own. Immediately following consummation of the Combinations, it is expected that former Ortho shareholders will own

32

approximately 38% of Topco and former Quidel stockholders will own approximately 62% of Topco, on a fully diluted basis, based on the respective capitalizations of Ortho and Quidel as of the date the parties entered into the BCA. The market value of the Topco Shares that Quidel stockholders will be entitled to receive when the Quidel Merger is completed and that Ortho shareholders will be entitled to receive when the Ortho Scheme is completed could vary significantly due to a change in the market value of Quidel Shares or Ortho Shares from the date the BCA was entered into, the date of this joint proxy statement/prospectus or the date of the Quidel Stockholders’ Meeting or the Ortho General Meeting. Because the applicable exchange ratios will not be adjusted to reflect any changes in the market value of Quidel Shares or Ortho Shares, such market price fluctuations may affect the relative value that Quidel stockholders will receive at the Quidel Effective Time and that Ortho shareholders will receive at the Ortho Effective Time. Share price changes may result from a variety of factors, including changes in the business, operations or prospects of Quidel or Ortho, market assessments of the likelihood that the Combinations will be completed, market assessments of the value of Topco, the timing of the Combinations, regulatory considerations, governmental actions, general market and economic conditions, legal proceedings and other factors, each of which may be beyond the control of Topco, Quidel or Ortho. Prior to making any investment decision, stockholders are urged to obtain updated market quotations for Quidel Shares and Ortho Shares.

The trading of Topco Shares after completion of the Combinations may cause the market price of Topco Shares to fall.

Following completion of the Combinations, Topco Shares are expected to be publicly traded on Nasdaq, enabling former Quidel stockholders and former Ortho shareholders to sell the Topco Shares that they receive in the Combinations. Such sales of Topco Shares may take place promptly following the Combinations and could have the effect of decreasing the market price for Topco Shares owned by former Quidel stockholders and Ortho shareholders below the market price of the Quidel Shares or Ortho Shares owned by such Quidel stockholders and Ortho shareholders, respectively, prior to completion of the Combinations.

The Combinations may be completed even though material adverse changes subsequent to the announcement of the Combinations, such as industry-wide changes or other events, may occur.

In general, either Quidel or Ortho can, on the terms and conditions set forth in the BCA, refuse to complete the Combinations if there is a material adverse change affecting the other party. However, some types of changes do not permit either Quidel or Ortho to refuse to complete the Combinations, even if such changes would have a material adverse effect on either of the parties. For example, a worsening of Quidel’s or Ortho’s financial condition or results of operations due to a decrease in commodity prices or general economic conditions, except to the extent affecting Quidel or Ortho, as applicable, in a disproportionate manner relative to other businesses operating in the industries in which they operate, or a drop in Quidel’s or Ortho’s stock price, would not give the other party the right to refuse to complete the Combinations. If adverse changes occur that affect either party, but the parties are still required to complete the Combinations, the share price of Topco Shares and the business and financial results of Topco may suffer.

The BCA contains provisions that restrict Ortho’s and Quidel’s ability to pursue alternatives to the Combinations and, in specified circumstances, would require Ortho or Quidel to pay the other party a termination fee.

Under the BCA, each of Ortho, Quidel and Topco is restricted, subject to certain exceptions, from soliciting, initiating, knowingly encouraging or facilitating, discussing or negotiating, or furnishing non-public information with regard to, any inquiry, proposal or offer for a competing acquisition proposal from any person or entity. If any party receives a competing acquisition proposal and such party’s board of directors determines (after consultation with such party’s financial advisors and outside legal counsel) that such proposal constitutes a Quidel All Cash Superior Proposal or an Ortho All Cash Superior Proposal, as the case may be, and the board of directors makes a change in recommendation in response to such proposal to the stockholders or shareholders of such company, Quidel, on the one hand, or Ortho, on the other hand, would be entitled, upon complying with certain requirements, to terminate the BCA, subject to the terms of the BCA. Under such circumstances, Quidel may be required to pay Ortho a termination fee of approximately $208 million, Ortho may be required to pay Quidel approximately $47 million, or either party may be required to reimburse the other party for its out-of-pocket expenses incurred in connection with the BCA. These provisions could discourage a third party that may have an interest in acquiring all or a significant part of either company from considering or proposing such an acquisition, even if such third party was prepared to enter into a transaction that would be more favorable to one of the companies and its respective stockholders or shareholders than the Combinations. See the sections entitled “The Business Combination Agreement—Acquisition Proposals,” “The Business Combination Agreement—Termination” and “The Business Combination Agreement—Expenses and Termination Fees” of this joint proxy statement/prospectus.

33

Quidel and Ortho will incur significant transaction and merger-related costs in connection with the Combinations.

Ortho and Quidel have incurred and expect to incur a number of non-recurring direct and indirect costs associated with the Combinations. These costs and expenses include fees paid to financial, legal and accounting advisors, severance and other potential employment-related costs, including payments that may be made to certain Ortho and Quidel executives, filing fees, printing expenses and other related charges. Some of these costs are payable by Ortho and Quidel regardless of whether the Combinations are completed. There are also processes, policies, procedures, operations, technologies and systems that must be integrated in connection with the Combinations and the integration of the two companies’ businesses. While both Ortho and Quidel have assumed that a certain level of expenses would be incurred in connection with the Combinations and the other transactions contemplated by the BCA and continue to assess the magnitude of these costs, there are many factors beyond their control that could affect the total amount or the timing of the integration and implementation expenses.

There may also be additional unanticipated significant costs in connection with the Combinations that Ortho and Quidel may not recoup. These costs and expenses could reduce the realization of efficiencies and strategic benefits Ortho and Quidel expect Topco to achieve from the Combinations. Although Ortho and Quidel expect that these benefits will offset the transaction expenses and implementation costs over time, this net benefit may not be achieved in the near term or at all.

In connection with the Combinations, Quidel, Ortho and/or Topco may be required to take write-downs or write-offs, restructuring and impairment or other charges that could negatively affect the business, assets, liabilities, prospects, outlook, financial condition and results of operations of Quidel, Ortho and/or Topco.

Although Quidel and Ortho have conducted extensive due diligence in connection with the Combinations and related transactions, they cannot assure you that this diligence revealed all material issues that may be present, that it would be possible to uncover all material issues through a customary amount of due diligence or that factors outside of Quidel’s and Ortho’s control will not later arise. Even if Quidel’s and Ortho’s due diligence successfully identifies certain risks, unexpected risks may arise and previously known risks may materialize in a manner not consistent with Quidel’s and Ortho’s preliminary risk analysis. Further, as a result of the Combinations, purchase accounting and the proposed operation of Topco going forward, Quidel, Ortho and/or Topco may be required to take write-offs or write-downs, restructuring and impairment or other charges. As a result, Quidel, Ortho and/or Topco may be forced to write-down or write-off assets, restructure its operations or incur impairment or other charges that could negatively affect the business, assets, liabilities, prospects, outlook, financial condition and results of operations of Quidel, Ortho and/or Topco.

After the Combinations, Quidel stockholders and Ortho shareholders will have a reduced ownership and voting interest in Topco than they currently have in Quidel and Ortho respectively, and will exercise less influence over Topco’s management.

Immediately following consummation of the Combinations, it is expected that former Ortho shareholders will own approximately 38% of Topco and former Quidel stockholders will own approximately 62% of Topco, on a fully diluted basis, based on the respective capitalizations of Ortho and Quidel as of the date the parties entered into the BCA. Consequently, former Quidel stockholders will have a reduced ownership of Topco than they currently have of Quidel and will exercise less influence over the management and policies of Topco than they currently have over the management and policies of Quidel. Former Ortho shareholders will have a reduced ownership of Topco than they currently have of Ortho and will exercise less influence over the management and policies of Topco than they currently have over the management and policies of Ortho.

In addition, pursuant to the terms of the BCA, following the closing of the Combinations, the Topco board of directors will initially be comprised of 12 directors, consisting of eight individuals designated by Quidel, expected to consist of Messrs. Bryant, Buechler, Michael, Strobeck, Widder and Wilkins and Mses. Polan and Rhoads, each of whom, other than Mr. Bryant, qualifies as an “independent director” under the applicable rules of Nasdaq, and four individuals designated by Ortho prior to closing, at least two of whom will qualify as an “independent director” under the applicable rules of Nasdaq. Following the closing of the Combinations, (i) Douglas Bryant, the current President and Chief Executive Officer of Quidel, will serve as Chair and Chief Executive Officer of Topco, (ii) Robert Bujarski will serve as President and Chief Operating Officer of Topco, (iii) Joseph Busky will serve as Chief Financial Officer of Topco, (iv) Michael Iskra will serve as Chief Commercial Officer of Topco and (v) each of the committees of the Topco board of directors will consist of one director designated by Ortho (who is reasonably acceptable to the Topco board of directors) and not less than two additional directors designated by Quidel.

34

Ortho and Quidel may have difficulty attracting, motivating and retaining executives and other key employees due to uncertainty associated with the Combinations.

Topco’s success after completion of the Combinations will depend in part upon the ability of Topco to retain key employees of Ortho and Quidel. Competition for qualified personnel can be intense. Current and prospective employees of Ortho or Quidel may experience uncertainty about the effect of the Combinations, which may impair Ortho’s and Quidel’s ability to attract, retain and motivate key management, sales, marketing, manufacturing, technical and other personnel prior to and following the Combinations. Employee retention may be particularly challenging during the pendency of the Combinations, as employees of Ortho and Quidel may experience uncertainty about their future roles with Topco.

In addition, pursuant to change in control and/or severance provisions in Ortho’s severance schemes and executive employment agreements, as well as severance provisions in Quidel’s executive employment agreements, certain key employees of Quidel and Ortho are entitled to receive severance payments upon certain qualifying terminations of their employment. Certain key Quidel and Ortho employees potentially could terminate their employment following specified circumstances set forth in the applicable executive severance scheme or employment agreement, including certain changes in such key employees’ title, status, authority, duties, responsibilities or compensation, and be entitled to receive severance. Such circumstances could occur in connection with the Combinations as a result of changes in roles and responsibilities.

While Quidel and Ortho may employ the use of certain retention programs, there can be no guarantee that they will prove to be successful. If key employees of Ortho or Quidel depart, the integration of the companies may be more difficult and Topco’s business following the Combinations may be harmed. Furthermore, Topco may be required to incur significant costs in identifying, hiring, training and retaining replacements for departing employees and may lose significant expertise and talent relating to the businesses of Ortho or Quidel, which may adversely affect Topco’s ability to realize the anticipated benefits of the Combinations. In addition, there could be disruptions to or distractions for the workforce and management associated with activities of labor unions or works councils or integrating employees into Topco. Accordingly, no assurance can be given that Topco will be able to attract or retain key employees of Ortho and Quidel to the same extent that those companies have been able to attract or retain their own employees in the past.

Ortho’s and Quidel’s business relationships may be subject to disruption due to uncertainty associated with the Combinations.

Companies with which Ortho or Quidel do business may experience uncertainty associated with the Combinations, including with respect to current or future business relationships with Ortho, Quidel or Topco. Ortho’s and Quidel’s business relationships may be subject to disruption as customers, distributors, suppliers, vendors and others may attempt to negotiate changes in existing business relationships or consider entering into business relationships with parties other than Ortho, Quidel or Topco. These disruptions could have an adverse effect on the businesses, financial condition, results of operations or prospects of Topco, including an adverse effect on Topco’s ability to realize the anticipated benefits of the Combinations. The risk and adverse effect of such disruptions could be exacerbated by a delay in completion of the Combinations.

The COVID-19 pandemic may adversely affect Quidel’s and Ortho’s ability to timely consummate the Combinations.

COVID-19 and the various precautionary measures attempting to limit its spread taken by many governmental authorities worldwide have had a severe effect on global markets and the global economy. The extent to which the COVID-19 pandemic impacts Quidel’s and Ortho’s respective business operations will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, new information that may emerge concerning the severity of COVID-19, the nature and extent of governmental actions taken to contain COVID-19 or treat its impact, the availability of effective treatments and vaccines, the ultimate duration of the pandemic and how quickly and to what extent normal economic and operating conditions can resume. COVID-19 and official actions in response to it have made it more challenging for Quidel, Ortho and relevant third parties to adequately staff their respective businesses and operations, and may cause delay in the companies’ ability to obtain the relevant approvals for the consummation of the Combinations. The spread of COVID-19 has caused Quidel and Ortho to modify their business practices (including employee travel, employee work locations and physical participation in meetings, events and conferences), and each of Quidel and Ortho may take further actions as may be required by government authorities or that Quidel or Ortho determines are in the best interests of their employees, customers, partners, and suppliers. Such measures may not mitigate fully the risks posed by the virus, impairing Quidel’s and Ortho’s ability to perform critical functions.

35

In response to increased COVID-19 testing demand, Quidel is continuing to rapidly and significantly expand its manufacturing capacity, including expanding and scaling its infrastructure to support existing and anticipated COVID-19 testing demand and commercial activities. This rapid expansion has placed and may continue to place significant strain on Quidel’s management, personnel, operations, systems and financial resources. Failure to successfully manage this expansion, including due to inefficiencies in implementing such expansion or higher costs for materials, technology, equipment and human capital during the intensity of the COVID-19 pandemic, could negatively affect Quidel’s or Topco’s operating results.

The respective opinions of Ortho’s and Quidel’s financial advisors will not reflect changes in circumstances between the signing of the BCA and the completion of the Combinations.

The Ortho board of directors and the Quidel board of directors received opinions from their respective financial advisors in connection with their determinations to approve the BCA, the Combinations and all other transactions contemplated by the BCA. However, Ortho and Quidel do not expect to receive updated opinions from their respective financial advisors prior to completion of the Combinations, and thus, the opinions do not speak as of the time of the Ortho Shareholder Meetings, the Quidel Stockholders’ Meeting or completion of the Combinations or as of any date other than the date of such opinions. Changes in the operations and prospects of Ortho or Quidel, general market and economic conditions and other factors that may be beyond the control of Ortho or Quidel and on which the financial advisors’ opinions were based may significantly affect the relative value of Ortho and Quidel and the prices of Ortho Shares or Quidel Shares by the time the Combinations are completed. As a result, the opinions will not address the fairness, from a financial point of view, of the Ortho Scheme Consideration to be received by Ortho shareholders or to be paid by Quidel, as applicable, at the times of such meetings or the time the Combinations are completed. For a description of the opinions that Ortho and Quidel received from their respective financial advisors, see the sections entitled “The Combinations—Opinion of J.P. Morgan Securities LLC as Financial Advisor to Ortho” and “The Combinations—Opinion of Perella Weinberg Partners LP as Financial Advisor to Quidel” of this joint proxy statement/prospectus.

Quidel’s and Ortho’s executive officers and directors have interests in the Combinations that may be different from the interests of Quidel stockholders or Ortho shareholders, respectively, generally.

When considering the recommendation of the Quidel board of directors that Quidel stockholders approve the Merger Proposal, Quidel stockholders should be aware that directors and executive officers of Quidel have certain interests in the Combinations that may be different from or in addition to the interests of Quidel stockholders generally. These interests include, but are not limited to, the treatment of Quidel equity awards in the Quidel Merger, severance protection provided for in compensation arrangements of certain executives, and potential changes to their roles and responsibilities with Topco following the completion of the Combinations. The Quidel board of directors was aware of these interests and considered them, among other things, in evaluating and negotiating the BCA and the Combinations and in recommending that the Quidel stockholders approve the Merger Proposal.

When considering the recommendation of the Ortho board of directors that Ortho shareholders approve the Ortho Scheme, Ortho shareholders should be aware that directors and executive officers of Ortho have certain interests in the Combinations that may be different from or in addition to the interests of Ortho shareholders generally. These interests include, but are not limited to, the treatment of Ortho equity compensation awards in the Ortho Scheme. The Ortho board of directors was aware of these interests and considered them, among other things, in evaluating and negotiating the BCA and the Combinations and in recommending that the Ortho shareholders approve the Ortho Scheme.

See the sections entitled “The Combinations—Background of the Combinations,” “Interests of Certain Persons in the Combinations” and “The Business Combination Agreement—Indemnification and Insurance” of this joint proxy statement/prospectus.

Completion of the Combinations may trigger change-in-control or other provisions in certain agreements that Quidel or Ortho is party to.

The completion of the Combinations may trigger change-in-control or other provisions in certain agreements that Quidel or Ortho is party to. If Quidel or Ortho, as applicable, is unable to negotiate waivers of those provisions, the respective counterparties may exercise their rights and remedies under the applicable agreements, including in some instances potentially terminating the agreements or seeking monetary damages. Even if Quidel or Ortho, as applicable, is able to negotiate waivers, the respective counterparties may require a fee for such waivers or seek to renegotiate the agreements on terms less favorable to the combined business.

36

If the Quidel Merger does not qualify as part of an exchange described under Section 351 of the Code or a “reorganization” within the meaning of Section 368(a) of the Code, U.S. stockholders of Quidel may be required to pay substantial U.S. federal income taxes. Likewise, if the Ortho Scheme does not qualify as part of an exchange described under Section 351 of the Code, U.S. shareholders of Ortho may be required to pay substantial U.S. federal income taxes.

For U.S. federal income tax purposes, the Combinations, taken together as a single integrated transaction, are intended to qualify as an exchange described under Section 351 of the Code and the payment of cash pursuant to the Combinations is intended to be treated as a payment pursuant to Section 351(b) of the Code (the “Intended Tax Treatment”). The Quidel Merger is also intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. All parties intend to report the Combinations consistent with the Intended Tax Treatment. However, neither Quidel nor Ortho intends to obtain a ruling from the IRS with respect to the tax consequences of the Combinations. If the IRS or a court determines that the Quidel Merger does not qualify as part of an exchange under Section 351 of the Code and does not qualify as a “reorganization” under Section 368(a) of the Code, a U.S. stockholder of Quidel would generally recognize taxable gain or loss upon the exchange of Quidel Shares for Topco Shares pursuant to the Combinations. If the IRS or a court determines that the Ortho Scheme does not qualify as part of an exchange under Section 351 of the Code, a U.S. shareholder of Ortho would generally recognize taxable gain or loss upon the exchange of its Ortho Shares for Topco Shares and cash pursuant to the Combinations (whereas if the Ortho Scheme qualifies as part of an exchange under Section 351 of the Code, the U.S. shareholder of Ortho would only recognize taxable gain on the exchange with respect to the cash portion of the consideration). See the section entitled “Material U.S. Federal Income Tax Considerations.”

Risks Relating to Topco Following Completion of the Combinations

In addition to the risks described below, you should carefully consider the risks discussed under “—Risks Relating to Quidel’s Business” and “—Risks Relating to Ortho’s Business,” as these risks will be applicable to the business of Topco following the completion of the Combinations.

The failure to integrate successfully the businesses of Quidel and Ortho in the expected timeframe would adversely affect Topco’s future business and financial performance following the Combinations.

The combination of two independent companies is a complex, costly and time-consuming process. As a result, the combined company will be required to devote significant management attention and resources to integrate the business practices and operations of Ortho and Quidel. The integration process may disrupt the business of either or both of the companies and, if implemented ineffectively, could preclude realization of the full benefits expected by Ortho and Quidel from the Combinations. The failure of Topco to meet the challenges involved in successfully integrating the operations of Ortho and Quidel or otherwise to realize the anticipated benefits of the Combinations could cause an interruption of the activities of Topco and could seriously harm its results of operations. In addition, the overall integration of the two companies may result in material unanticipated problems, expenses, liabilities, competitive responses, loss of customer relationships and diversion of management’s attention, and may cause Topco’s stock price to decline. The difficulties of combining the operations of Quidel and Ortho include, among others:

| • |  | managing a significantly larger company;

| • |  | coordinating geographically separate organizations, including extensive international operations;

| • |  | the potential diversion of management’s focus and resources from other strategic opportunities and from operational matters;

| • |  | performance shortfalls at one or both of the companies as a result of the diversion of management’s attention caused by completing the Combinations and integrating the companies’ operations;

| • |  | aligning and executing the strategy of Topco;

| • |  | retaining existing customers and attracting new customers;

| • |  | maintaining employee morale and retaining key management and other employees;

| • |  | the disruption of, or the loss of momentum in, each company’s ongoing business or inconsistencies in standards, controls, systems, procedures and policies;

| • |  | integrating two unique business cultures, which may prove to be incompatible;

| • |  | the possibility of faulty assumptions underlying expectations regarding the integration process;

37

| • |  | consolidating corporate and administrative infrastructures and eliminating duplicative operations;

| • |  | coordinating distribution and marketing efforts;

| • |  | integrating IT, communications and other systems;

| • |  | changes in applicable laws and regulations;

| • |  | managing tax costs or inefficiencies associated with integrating the operations of Quidel and Ortho;

| • |  | unforeseen expenses or delays associated with the Combinations; and

| • |  | taking actions that may be required in connection with obtaining regulatory approvals.

Many of these factors will be outside of Topco’s control and any one of them could result in increased costs, decreased revenues and diversion of management’s time and energy, which could materially impact the combined company’s business, financial condition and results of operations. In addition, even if the operations of Ortho and Quidel are integrated successfully, Topco may not realize the full benefits of the Combinations, including the synergies, cost savings or sales or growth opportunities that Ortho and Quidel expect. These benefits may not be achieved within the anticipated timeframe, or at all. As a result, Ortho and Quidel cannot assure their respective shareholders and stockholders that the combination of Ortho and Quidel will result in the realization of the full benefits anticipated from the Combinations.

The synergies attributable to the Combinations may vary from expectations.

Topco may fail to realize the anticipated benefits and synergies expected from the Combinations, which could adversely affect its business, financial condition and operating results. The success of the Combinations will depend, in significant part, on Topco’s ability to successfully integrate the businesses of Quidel and Ortho and realize the anticipated strategic benefits and synergies from the Combinations. Quidel and Ortho believe that the combination of the two businesses will complement each party’s strategy by providing a balanced and diversified product portfolio, operational efficiencies, supply chain optimization, complementary geographic footprints, product development synergies and cash flow and margin enhancement opportunities. However, achieving these goals requires, among other things, realization of the targeted cost synergies expected from the Combinations. The anticipated benefits of the Combinations and actual operating, technological, strategic and revenue opportunities may not be realized fully or at all, or may take longer to realize than expected. If Topco is not able to achieve these objectives and realize the anticipated benefits and synergies expected from the Combinations within the anticipated timeframe or at all, Topco’s business, financial condition and operating results may be adversely affected.

The future results of Topco will suffer if Topco does not effectively manage its expanded operations following the Combinations.

Following the Combinations, the size of the business of Topco will increase significantly beyond the current size of either Quidel’s or Ortho’s business. Topco’s future results depends, in part, upon its ability to manage this expanded business, which will pose substantial challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. There can be no assurance that Topco will be successful or that it will realize the expected operating efficiencies, cost savings, revenue enhancements and other benefits currently anticipated from the Combinations.

Business issues currently faced by Quidel or Ortho may be imputed to the operations of the other.

To the extent either Quidel or Ortho currently has, or is perceived by customers to have, operational challenges, such as service performance, safety issues or workforce issues, those challenges may raise concerns by existing customers of the other company following the Combinations, which may limit or impede Topco’s future ability to obtain additional business from those customers.

Topco will be subject to certain risks relating to Ortho’s indebtedness.

In connection with the consummation of the Combinations, Ortho’s current net debt of $2.0 billion is expected to continue to be outstanding, and as a result, Topco will be subject to certain risks related to this indebtedness. For a discussion of the risks relating to this indebtedness and the related debt instruments, including the requirement to comply with certain covenants that may restrict Topco from realizing the anticipated benefits and synergies expected from the Combinations, see “—Risks Relating to Ortho’s Business—Risks Relating to Ortho’s Indebtedness.”

38

No trading market currently exists for Topco Shares.

Prior to the Combinations, no trading market exists for Topco Shares. Upon the closing of the Combinations, the Topco Shares are expected to be listed for trading on Nasdaq. However, there can be no assurance that an active trading market for Topco Shares will develop after the closing of the Combinations, or if it develops, that such market will be sustained. In the absence of an active trading market for the Topco Shares, investors may not be able to sell their Topco Shares at the time that they would like to sell.

The market price of Topco Shares may be volatile.

The market price of Topco Shares may be volatile. Broad general economic, political, market and industry factors may adversely affect the market price of Topco Shares, regardless of Topco’s actual operating performance and the success of the integration of Quidel and Ortho. Factors that could cause fluctuations in the price of Topco Shares include:

| • |  | actual or anticipated variations in quarterly operating results and the results of competitors;

| • |  | changes in financial projections by Topco, if any, or by any securities analysts that may cover Topco Shares;

| • |  | conditions or trends in the industry, including regulatory changes or changes in the securities marketplace;

| • |  | announcements by Topco or its competitors of significant acquisitions, strategic partnerships or divestitures;

| • |  | announcements of investigations or regulatory scrutiny of Topco’s operations or lawsuits filed against it;

| • |  | additions or departures of key personnel; and

| • |  | issuances or sales of Topco Shares, including sales of shares by Topco’s directors and officers or its key investors.

Future sales of Topco Shares by Topco or its stockholders in the public market, or the perception that such sales may occur, could reduce the price of Topco Shares, and any additional capital raised by Topco through the sale of equity or convertible securities may dilute ownership in Topco.

The sale of Topco Shares in the public market, or the perception that such sales could occur, could harm the prevailing market price of Topco Shares. These sales, or the possibility that these sales may occur, also might make it more difficult for Topco to sell equity securities in the future at a time and at a price that Topco deems appropriate.

After the completion of the Combinations, Topco is expected to have approximately 66.7 million outstanding Topco Shares. Following the completion of the Combinations, it is expected that former Ortho shareholders will own approximately 38% of Topco and former Quidel stockholders will own approximately 62% of Topco, on a fully diluted basis, based on the respective capitalizations of Ortho and Quidel as of the date the parties entered into the BCA.

All Topco Shares that will be issued in connection with the Combinations are expected to be freely tradable without restriction or further registration under the Securities Act, except for any Topco Shares held by Topco’s affiliates, as that term is defined under Rule 144 of the Securities Act (“Rule 144”), including certain of Topco’s directors, executive officers and other affiliates, which shares may be sold in the public market only if they are registered under the Securities Act or are sold pursuant to an exemption from registration such as Rule 144. Following the completion of the Combinations, Topco Shares covered by registration rights are expected to represent approximately 19% of Topco’s outstanding Topco Shares. Registration of any of these outstanding Topco Shares would result in such shares becoming freely tradable without compliance with Rule 144 upon effectiveness of the registration statement. As restrictions on resale end or if these stockholders exercise their registration rights, the market price of Topco Shares could drop significantly if the holders of these Topco Shares sell them or are perceived by the market as intending to sell them. These factors could also make it more difficult for Topco to raise additional funds through future offerings of Topco Shares or other securities.

In addition, Topco intends to file a registration statement with the SEC on Form S-8 providing for the registration of [●] Topco Shares issued or reserved for issuance under the Quidel 2018 Equity Plan, as proposed to be amended and assumed by Topco. Subject to the satisfaction of vesting conditions, shares registered under the registration statement on Form S-8 may be made available for resale immediately in the public market without restriction.

In the future, Topco may also issue its securities in connection with investments or acquisitions, or otherwise. Topco cannot predict the size of future issuances of Topco Shares or securities convertible into Topco Shares or the effect, if any, that future issuances and sales of Topco Shares will have on the market price of Topco Shares. Sales of substantial amounts of Topco Shares (including shares issued in connection with an acquisition), or the perception that such sales could occur, may adversely affect prevailing market prices of Topco Shares.

39

If securities or industry analysts do not publish research or reports about Topco, the trading price of Topco Shares could decline.

The trading market for Topco Shares will be influenced by any research and reports that industry or securities analysts publish about Topco or its business. If one or more of these analysts cease coverage of Topco or fail to publish reports on Topco regularly, Topco could lose visibility in the financial markets, which in turn could cause Topco’s stock price or trading volume to decline. Moreover, if one or more of the analysts who cover Topco downgrade the Topco Shares or if Topco’s operating results do not meet their expectations, the trading price of Topco Shares could decline.

Topco Shares to be received by Ortho shareholders and Quidel stockholders as a result of the Combinations will have rights different from the Ortho Shares and Quidel Shares that they hold prior to the Effective Times of the Combinations.

Upon completion of the Combinations, the rights of former Ortho shareholders and Quidel stockholders who become stockholders of Topco will be governed by the certificate of incorporation of Topco (the “Topco Charter”) and the bylaws of Topco (the “Topco Bylaws”) and by the DGCL. The rights associated with Ortho Shares and Quidel Shares are different from the rights associated with Topco Shares. See the section entitled “Comparison of Rights of Stockholders of Quidel, Ortho and Topco” of this joint proxy statement/prospectus.

The Topco Bylaws will designate the Court of Chancery of the State of Delaware (the “Court of Chancery”) as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by Topco’s stockholders, which could limit Topco’s stockholders’ ability to obtain a favorable judicial forum for disputes with Topco or its directors, officers, employees or agents.

The Topco Bylaws after the Combinations will provide that, unless Topco consents in writing to the selection of an alternative forum, (i) the Court of Chancery (or, if the Court of Chancery does not have, or declines to accept, jurisdiction, another state court or a federal court located within the State of Delaware) will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for any claims (other than any cause of action arising under the Securities Act), including claims in the right of Topco that are based upon a violation of duty by a current or former director, officer, employee or stockholder in such capacity, or as to which the DGCL confers jurisdiction upon the Court of Chancery, and (ii) the federal district courts of the United States of America will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for any cause of action arising under the Securities Act but that the forum selection provision will not apply to claims brought to enforce a duty or liability created by the Exchange Act. Any person or entity purchasing or otherwise acquiring any interest in shares of Topco’s capital stock will be deemed to have notice of, and to have consented to, the provisions of the Topco Bylaws described in the preceding sentence. This forum selection provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with Topco or its directors, officers, employees or agents, which may discourage such lawsuits against Topco and such persons and result in increased costs for a stockholder to bring a claim. There is uncertainty as to whether a court would enforce such provisions. If a court were to find these provisions of the Topco Bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, Topco may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect Topco’s business, financial condition or results of operations.

If Topco fails to develop or maintain an effective system of internal controls, it may not be able to accurately report its financial results or prevent fraud. As a result, stockholders could lose confidence in Topco’s financial reporting, which would harm its business and the trading price of Topco Shares.

Effective internal controls are necessary for Topco to provide reliable financial reports, prevent fraud and operate successfully as a public company. If Topco cannot provide reliable financial reports or prevent fraud, its reputation and operating results would be harmed. Topco cannot be certain that its efforts to develop and maintain an effective system of internal controls will be successful, that it will be able to maintain adequate controls over its financial processes and reporting in the future, or that it will be able to comply with its obligations under Section 404 of the Sarbanes-Oxley Act of 2002. Any failure to develop or maintain effective internal controls, or difficulties encountered in implementing or improving internal controls, could harm Topco’s operating results or cause Topco to fail to meet its reporting obligations. Ineffective internal controls could also cause investors to lose confidence in Topco’s reported financial information, which would likely have a negative effect on the trading price of the Topco Shares.

40

Topco’s IT systems may be vulnerable to hacker intrusion, malicious viruses and other cybercrime attacks, which may harm its business and expose it to liability.

Topco’s operations will depend to a great extent on the reliability and security of its IT systems, software and network, which are subject to damage and interruption caused by human error, problems relating to telecommunications networks, software failure, natural disasters, sabotage, viruses and similar events. Any interruption in Topco’s IT systems could have a negative effect on the quality of products and services offered and, as a result, on customer demand and volume of sales.

Topco will be exposed to significant risks in relation to compliance with anti-corruption laws and regulations and economic sanctions programs.

Doing business on a worldwide basis will require the combined company to comply with the laws and regulations of various jurisdictions, and Topco’s failure to successfully comply with these rules and regulations may expose it to liabilities. These laws and regulations apply to companies, individual directors, officers, employees and agents, and may restrict the combined company’s operations, trade practices, investment decisions and partnering activities. In particular, Topco’s international operations are subject to anti-corruption and anti-bribery laws and regulations, such as the U.S. Foreign Corrupt Practices Act of 1977 (the “FCPA”), the UK Bribery Act of 2010 (the “Bribery Act”) and the Brazilian Anti-Bribery Act (also known as the Brazilian Clean Company Act), among others, and economic and trade sanctions, including those administered by the United Nations, the European Union, the Office of Foreign Assets Control of the U.S. Department of the Treasury (“OFAC”) and the U.S. Department of State. The FCPA prohibits providing anything of value to foreign officials for the purposes of obtaining or retaining business or securing any improper business advantage. Topco may deal with state-owned business enterprises, the employees and representatives of which may be considered foreign officials for purposes of the FCPA. Topco is subject to the jurisdiction of various governments and regulatory agencies outside of the United States, which may bring Topco’s personnel into contact with foreign officials responsible for issuing or renewing permits, licenses or approvals or for enforcing other governmental regulations. The provisions of the Bribery Act extend beyond bribery of foreign public officials and are more onerous than the FCPA in a number of other respects, including jurisdiction, non-exemption of facilitation payments and penalties. Economic and trade sanctions restrict Topco’s transactions or dealings with certain sanctioned countries, territories and designated persons, absent authorizations or exemptions under applicable law, such as OFAC’s licenses permitting certain humanitarian trade.

As a result of doing business in foreign countries, including through partners, distributors, agents and other third parties acting on Topco’s behalf, Topco will be exposed to a risk of violating anti-corruption and anti-bribery laws and sanctions regulations. Some of the international locations in which Topco will operate have developing legal systems and may have higher levels of corruption than more developed nations. Topco’s continued expansion and worldwide operations, including in developing countries, its development of joint-venture relationships worldwide and the employment of local agents in the countries in which Topco will operate increase the risk of violations of anti-corruption and anti-bribery laws and economic and trade sanctions. Though these distributors, manufacturers and other third parties acting on Topco’s behalf are not Topco’s affiliated legal entities, such violations could expose Topco to FCPA liability or liabilities under similar laws of the various jurisdictions in which Topco operates and/or Topco’s reputation may potentially be harmed by the third parties. Violations of anti-corruption and anti-bribery laws and economic and trade sanctions are punishable by civil penalties, including fines, denial of export privileges, injunctions, asset seizures, debarment from government contracts (and termination of existing contracts) and revocations or restrictions of licenses, as well as criminal fines and imprisonment. In addition, any major violations could have a significant impact on Topco’s reputation and consequently on its ability to win future business.

While Ortho and Quidel believe that Topco will have a strong culture of compliance and an adequate system of internal controls, including procedures to minimize and detect fraud in a timely manner, as well as processes for complying with OFAC authorizations or exemptions, Ortho and Quidel will seek to continuously improve Topco’s system of internal controls and to remedy any weaknesses identified. There can be no assurance, however, that Topco’s policies and procedures will be followed at all times or will effectively detect and prevent violations of the applicable laws by one or more of its employees, consultants, agents or partners and, as a result, Topco could be subject to penalties and material adverse consequences on its business, financial condition or results of operations.

Topco’s ability to utilize the U.S. net operating loss carryforwards may be limited.

The ability of Topco and its affiliates, including Quidel and Ortho, to utilize any U.S. federal net operating loss carryforwards (“NOLs”) and other tax attributes existing at the time of the Combinations to reduce future taxable income

41

following the consummation of the Combinations is subject to limitations under U.S. federal income tax laws and depends on many factors, including its future income, which cannot be assured. In addition, Section 382 of the Code (“Section 382”) generally imposes an annual limitation on the amount of NOLs that may be used to offset taxable income when a corporation has undergone an “ownership change” (as determined under Section 382), as is expected to be the case for Ortho following the Combinations. An ownership change generally occurs if one or more stockholders (or groups of stockholders) who are each deemed to own at least 5% of such corporation’s stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. Section 382 may apply as a result of the Combinations and limit the use of any NOLs prior to their expiration.

Topco and its subsidiaries will be subject to U.S. and foreign tax laws, and changes to such tax laws or differing interpretation of those laws by the relevant governmental authorities could adversely affect Topco.

The U.S. Congress, the Organisation for Economic Co-operation and Development and other government agencies in jurisdictions where Topco and its affiliates do business have had an extended focus on issues related to the taxation of multinational corporations. One example is in the area of “base erosion and profit shifting,” where payments are made between affiliates from a jurisdiction with high tax rates to a jurisdiction with lower tax rates. Additionally, changes proposed by the current U.S. administration, including significant tax reform, could significantly change the U.S. federal income tax rules and regulations applicable to Topco and its affiliates, although the prospect of tax reform, and the nature of any such reform, remains highly uncertain. Thus, the tax laws in the United States, the United Kingdom and other countries in which Topco and its affiliates do business could change on a prospective or retroactive basis, and any such changes could adversely affect Topco.

In addition, the tax laws and regulations in the United States, the United Kingdom and the numerous other jurisdictions in which Topco and its subsidiaries operate are inherently complex, and Topco and its subsidiaries will be obligated to make judgments and interpretations about the application of these laws and regulations to Topco and its subsidiaries and their operations and businesses. The interpretation and application of these laws and regulations could be challenged by the relevant governmental authorities, which could result in material administrative or judicial procedures, actions or sanctions.

The unaudited prospective financial information for Quidel and Ortho included in this joint proxy statement/prospectus reflects management estimates and may not prove to be reflective of actual future financial results.

In connection with the Combinations, Quidel and Ortho prepared and considered, among other things, certain internal, unaudited prospective financial information for Quidel and Ortho. This unaudited prospective financial information included assumptions regarding future market conditions, operating cash flows, expenditures and growth of Quidel and Ortho, as applicable. This internal, unaudited prospective financial information speaks only as of the date made and, except as required by applicable securities laws, will not be updated. This unaudited prospective financial information is subject to significant economic, competitive, industry and other uncertainties, which may cause the unaudited prospective financial information or the underlying assumptions to be inaccurate. As a result of these contingencies, there can be no assurance that the unaudited prospective financial information of Quidel and Ortho will be achieved in full, at all or within projected timeframes. In light of these uncertainties, the inclusion of the unaudited prospective financial information of Quidel and Ortho in this joint proxy statement/prospectus should not be regarded as an indication that the Quidel board of directors, the Ortho board of directors, Quidel, Ortho, Perella Weinberg or J.P. Morgan or any other recipient of this information considered, or now considers, it to be an assurance of the achievement of future financial results.

The unaudited prospective financial information was prepared for internal use and to assist Quidel and Ortho with their due diligence investigations and their respective financial advisors with their respective financial analyses. The unaudited prospective financial information was not prepared with a view toward public disclosure or toward compliance with published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. The prospective financial information included in this joint proxy statement/prospectus has been prepared by, and is the responsibility of, Quidel’s and Ortho’s management. Ernst & Young LLP (Quidel’s independent registered public accounting firm) and PricewaterhouseCoopers LLP (Ortho’s independent registered public accounting firm) have not audited, reviewed, examined, compiled nor applied agreed-upon procedures with respect to the accompanying prospective financial information and, accordingly, Ernst & Young LLP and PricewaterhouseCoopers LLP have not expressed an opinion or any other form of assurance with respect thereto. The Ernst & Young LLP report incorporated by reference into this joint proxy statement/prospectus relates to Quidel’s previously issued financial statements and the PricewaterhouseCoopers LLP report included in this joint proxy statement/prospectus

42

relates to Ortho’s previously issued financial statements. The reports do not extend to the prospective financial information and should not be read to do so. For additional information regarding the unaudited prospective financial information, see the section entitled “The Combinations—Unaudited Forward-Looking Financial Information” of this joint proxy statement/prospectus.

Topco’s actual financial position and results of operations may differ materially from the unaudited pro forma financial information included in this joint proxy statement/prospectus.

Topco has been recently incorporated and has no operating history and no revenues. While the unaudited pro forma financial information contained in this joint proxy statement/prospectus represents the best estimates of Quidel’s and Ortho’s management, it is presented for illustrative purposes only and may not be an accurate indication of Topco’s financial position or results of operations if the Combinations and associated financing transactions are completed on the dates indicated. The unaudited pro forma financial information has been derived from the audited and unaudited historical financial statements of Ortho and Quidel and certain adjustments and assumptions have been made regarding Topco after giving effect to the Combinations. The unaudited pro forma financial information does not include any fair value adjustments associated with the assets and liabilities of Ortho with the exception of the fair value of long-term borrowings and intangible assets, as Quidel and Ortho’s management have preliminarily concluded that these historical carrying values approximate their fair values as of September 30, 2021. The process for estimating the fair value of acquired assets and assumed liabilities requires the use of judgment in determining the appropriate assumptions and estimates. These estimates may be revised as additional information becomes available and as additional analyses are performed. Differences between preliminary estimates in the unaudited pro forma financial information and the final acquisition accounting will occur and could have a material impact on the unaudited pro forma financial information and Topco’s financial position and future results of operations.

In addition, the assumptions used in preparing the unaudited pro forma financial information may not prove to be accurate, and other factors may affect Topco’s financial condition or results of operations following the closing of the Combinations. Any potential decline in Topco’s financial condition or results of operations may cause significant fluctuations in the price of Topco Shares. See the section entitled “Unaudited Pro Forma Combined Financial Information” of this joint proxy statement/prospectus.

Topco will be exposed to foreign currency exchange risk.

Upon completion of the Combinations, Topco will transact business in numerous countries around the world and expects that a significant portion of its business will continue to take place in international markets. Topco will conduct its business and prepare its consolidated financial statements in its functional currency, while the financial statements of each of its subsidiaries will be prepared in the functional currency of that entity and the business of that entity will be conducted in the functional currency of that entity. Accordingly, fluctuations in the exchange rate of the functional currencies of Topco’s foreign currency entities against the functional currency of Topco will impact its results of operations and financial condition. Accordingly, it is expected that Topco’s revenues and earnings will be exposed to the risks that may arise from fluctuations in foreign currency exchange rates, which could have a material adverse effect on Topco’s business, results of operations or financial condition.

A downgrade in Topco’s or its subsidiaries’ credit ratings following the Combinations could impact Topco’s access to capital and cost of doing business.

Following the Combinations, rating agencies may re-evaluate Topco’s and its subsidiaries’ credit ratings, and any additional actual or anticipated downgrades in such credit ratings could limit Topco’s ability to access credit and capital markets, or to restructure or refinance its indebtedness. As a result of any such downgrades, future financings or refinancings may result in higher borrowing costs and require more restrictive terms and covenants, including obligations to post collateral with third parties, which may further restrict operations and negatively impact liquidity.

Credit rating agencies perform independent analyses when assigning credit ratings. Each analysis includes a number of criteria, including, but not limited to, business composition, market and operational risks, and various financial tests. Credit rating agencies continue to review the criteria for industry sectors and various debt ratings and may make changes to those criteria from time to time. Credit ratings are not recommendations to buy, sell or hold investments in the rated entity. Ratings are subject to revision or withdrawal at any time by the rating agencies, which could have a material adverse effect on Topco’s business, results of operations or financial condition.

43

Risks Relating to Quidel’s Business

In addition to the foregoing risks, Quidel is, and will continue to be, and the combined company will be, subject to the risks described in Quidel’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, as such risks may be updated or supplemented in Quidel’s subsequently filed Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, to the extent incorporated by reference into this joint proxy statement/prospectus, other than to the extent inconsistent with the risks described in the section entitled “—Risks Relating to Topco Following Completion of the Combinations.” See the section entitled “Where You Can Find More Information” of this joint proxy statement/prospectus.

Risks Relating to Ortho’s Business

In addition to the foregoing risks, Ortho is, and will continue to be, and the combined company will be, subject to the risks described below, as such risks may be updated or supplemented in Ortho’s subsequently filed Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, to the extent incorporated by reference into this joint proxy statement/prospectus, other than to the extent inconsistent with the risks described in the section entitled “—Risks Relating to Topco Following Completion of the Combinations.” See the section entitled “Where You Can Find More Information” of this joint proxy statement/prospectus.

Ortho has significant international sales and operations and faces risks related to health epidemics, including the ongoing global pandemic related to COVID-19. Ortho’s business, consolidated results of operations, financial position and cash flows have been and may continue to be negatively affected by the COVID-19 pandemic.

Any significant outbreak of contagious diseases and other adverse public health developments in countries where Ortho operates could have a material and adverse effect on Ortho’s business, financial condition and results of operations. Since the World Health Organization characterized COVID-19 as a pandemic in March 2020, COVID-19 has continued to spread throughout the United States and globally and it remains unclear when the COVID-19 pandemic will abate. Although the U.S. Food and Drug Administration (the “FDA”) has approved certain therapeutics and authorized three COVID-19 vaccines for emergency use, there has been some public resistance in the implementation of a national vaccine program, new strains of COVID-19 have been and may continue to be discovered, and the efficacy of the existing vaccines with respect to any such newly discovered strain of COVID-19 remains uncertain. The COVID-19 pandemic has resulted, and future significant outbreaks of contagious diseases in the human population could result, in a widespread health crisis that could adversely affect the economies and financial markets of many countries, resulting in an economic downturn that could affect demand for Ortho’s products and services and, as a result, likely impact Ortho’s operating results.

Many countries, including the United States, have and may continue to restrict travel and/or temporarily close businesses, schools and other public gathering spaces. Further, significant governmental measures, both in the United States and globally, have been and may continue to be implemented to control the spread of the virus, including restrictions on manufacturing, shipping and the movement of employees. As a result of such restrictions, Ortho has and may continue to experience some restrictions on its ability to efficiently distribute its products in the regions affected.

The COVID-19 pandemic has also resulted in global supply chain challenges and during the quarter ended October 3, 2021, Ortho began to experience some supply chain disruptions. For instance, supply chain shortages of certain key components of Ortho’s instruments and assays are affecting Ortho’s ability to fulfill customer orders on a timely basis and have had, and are expected to continue to have, a negative impact on Ortho’s business and results of operations, which could be material. Although Ortho and its contract manufacturer partners, suppliers of raw materials and other third-party vendors are pursuing additional sources for certain of these components, Ortho may be unable to identify additional suppliers and expects that these shortages and other supply chain challenges will continue to impact its business. Ortho has and may continue to encounter increases in idle facility costs and freight and distribution costs, which in some instances have affected the pricing of Ortho’s products. Any prolonged and significant supply chain disruptions or inability to provide products in countries adversely impacted by the COVID-19 pandemic would continue to impact Ortho’s revenues, increase Ortho’s costs and negatively affect Ortho’s business relationships and reputation, as well as Ortho’s operating results. It is also possible that Ortho will experience an adverse impact on collections and timing of cash receipts from its customers as a result of the impact of the COVID-19 pandemic, which could result in significant fluctuations in Ortho’s cash flows from period to period during the pandemic and in the periods that follow the end of the COVID-19 pandemic.

Ortho maintains a direct or indirect commercial presence in more than 130 countries and territories, with a direct presence in 36 countries, including in countries that have been severely impacted by the COVID-19 pandemic. Government imposed

44

travel restrictions and local statutory quarantines, as well as the potential impact to personnel, to the extent Ortho’s employees become ill, may result in direct operational and administrative disruptions. Ortho’s business may also be impacted by the imposition of government orders relating to COVID-19 vaccination status or regular testing of Ortho’s employees, which could result in the loss of employees and may impact Ortho’s ability to manufacture or ship its products. Ortho may also face increased risks of disputes with Ortho’s business partners, litigation and governmental and regulatory scrutiny as a result of the effects of COVID-19.

Health regulatory agencies globally may also experience disruptions in their operations as a result of the COVID-19 pandemic. The FDA and comparable foreign regulatory agencies may have slower response times or be under-resourced and, as a result, review and approval of product registrations may be materially delayed. For example, as health authorities have redeployed resources to focus on the management of the pandemic, there is a reduction in available capacity for the review and approval of other less-critical product submissions. As a result, manufacturers may incur a delay in obtaining product registrations.

Ortho cannot reasonably estimate the length or severity of the COVID-19 pandemic. The extent to which the COVID-19 pandemic, in particular, impacts Ortho’s business or results will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity and duration of the COVID-19 pandemic and the actions to contain it or treat its impact, among others.

To the extent the COVID-19 pandemic adversely affects Ortho’s business and financial results or those of Ortho’s customers, it may also have the effect of heightening many of the other risks described in this “Risk Factors” section. The ultimate impact of the COVID-19 outbreak on Ortho’s business, financial condition and results of operations depends on many factors, including those discussed above, that are not within Ortho’s control.

Ortho faces significant competition, and Ortho’s failure to compete effectively could adversely affect Ortho’s sales and results of operations.

The markets in which Ortho and Ortho’s competitors operate are rapidly evolving, and developments are expected to continue at a rapid pace. Competition in these markets is intense and expected to increase as new products, services and technologies become available and as new competitors enter the market. Ortho faces competition from diagnostics divisions of large multinational healthcare companies and conglomerates. Some of Ortho’s existing or potential competitors have substantially greater research and development capabilities, clinical, manufacturing, regulatory and marketing experience and financial and managerial resources than Ortho does. Some of these competitors are divisions or subsidiaries of corporations with substantial resources. Ortho’s sales and results of operations may be adversely affected by:

| • |  | customers’ perceptions of the comparative quality of Ortho’s competitors’ products or services;

| • |  | Ortho’s ability to manufacture, in a cost-effective way, sufficient quantities of Ortho’s products to meet customer demand;

| • |  | the ability of Ortho’s competitors to develop products, services and technologies that are more effective than Ortho’s or that render Ortho’s obsolete;

| • |  | Ortho’s competitors’ ability to obtain patent protection or other intellectual property rights that would prevent Ortho from offering competing products or services;

| • |  | the ability of Ortho’s competitors to obtain regulatory approval for the commercialization of products or services more rapidly or effectively than Ortho does; and

| • |  | competitive pricing by Ortho’s competitors.

Ortho expects competition to intensify in the future as more companies enter Ortho’s markets. Increased competition and potential new entrants in these industries may result in lower prices and volumes, higher costs for resources and lower profitability for Ortho. Moreover, competitive and regulatory conditions in many markets in which Ortho and Ortho’s competitors operate restrict Ortho’s ability to fully recover through price increases, higher costs of acquired goods and services resulting from inflation, and other drivers of cost increases. Ortho may not be able to supply customers with products and services that they deem superior and at competitive prices, and Ortho may lose business to Ortho’s competitors. Ortho also faces risks related to customers finding alternative methods for testing, which could result in lower demand for

45

Ortho’s products. If Ortho is unable to compete successfully in these highly competitive industries, it could have a material effect on Ortho’s business, financial condition and results of operations.

Ortho may experience difficulties that delay or prevent Ortho’s development, introduction or marketing of new or enhanced products or services.

Ortho’s success depends on Ortho’s ability to effectively introduce new and competitive products and services. The development of new or enhanced products or services is a complex, costly and uncertain process and is becoming increasingly complex and uncertain in the United States. Furthermore, developing and manufacturing new products and services requires Ortho to anticipate customers’ and patients’ needs and emerging technology trends accurately. Ortho may experience research and development, manufacturing, regulatory, marketing and other difficulties that could delay or prevent Ortho’s introduction of new or enhanced products and services, including the timelines for the introduction of new products as described in this joint proxy statement/prospectus. The research and development process in the healthcare industry generally takes a significant amount of time from design stage to product launch. This process is conducted in various stages, and each stage presents the risk that Ortho will not achieve its goals. In addition, innovations may not be accepted quickly in the marketplace because of, among other things, entrenched patterns of clinical practice or uncertainty over third-party reimbursements. In the event of such failure, Ortho may have to abandon a product in which it has invested substantial resources. Ortho cannot be certain that:

| • |  | any of Ortho’s products or services under development will prove to be safe and effective in clinical trials;

| • |  | Ortho will be able to obtain, in a timely manner or at all, necessary regulatory approvals;

| • |  | the products and services Ortho develops can be manufactured or provided at acceptable cost and with appropriate quality; or

| • |  | these products and services, if and when approved, can be successfully marketed.

These factors, as well as manufacturing or distribution problems or other factors beyond Ortho’s control, could delay the launch of new products or services. Any delay in the development, approval, production, marketing or distribution of a new product or service could materially and adversely affect Ortho’s competitive position, Ortho’s branding and Ortho’s results of operations. Additionally, customers could adopt alternative technologies, instead of Ortho’s technology, which could result in lower demand for Ortho’s products.

Global market, economic and political conditions may adversely affect Ortho’s operations and performance.

The growth of Ortho’s business and demand for Ortho’s products are affected by changes in the health of the overall global economy and, in particular, of the healthcare industry. Demand for Ortho’s products and services could change more dramatically than in previous years based on activity, funding reimbursement constraints and support levels from governments, universities, hospitals and the private industry, including laboratories. Ortho’s global business is adversely affected by decreases in the general level of economic activity, such as decreases in business and consumer spending, increases in unemployment rates and budgeting constraints of governmental entities. Disruptions in the United States, Europe or in other economies, or weakening of emerging markets, including China, could adversely affect Ortho’s sales, profitability and/or liquidity.

Ortho cannot assure you that there will not be a future deterioration in financial markets or confidence in major economies. These economic developments affect businesses such as Ortho’s in a number of ways. A tightening of credit in financial markets could adversely affect the ability of Ortho’s customers and suppliers to obtain financing for significant purchases and operations, could result in a decrease in or cancellation of orders for Ortho’s products and services and could impact the ability of Ortho’s customers to make payments. Similarly, a tightening of credit may adversely affect Ortho’s supplier base and increase the potential for one or more of Ortho’s suppliers to experience financial distress or bankruptcy. Ortho’s financial position, results of operations and cash flows could be materially adversely affected by difficult conditions and volatility in the capital, credit and commodities markets. Difficult conditions in these markets or in the overall economy could affect Ortho’s business in a number of ways. For example:

| • |  | under such conditions, Ortho cannot assure you that borrowings under Ortho’s multicurrency senior secured revolving facility with commitments of $500.0 million (the “Revolving Credit Facility”) will be available or sufficient, and in such a case, Ortho may not be able to obtain additional financing on reasonable terms or at all; and

46

| • |  | in order to respond to market conditions, Ortho may need to seek waivers of various provisions in the credit agreement governing Ortho’s senior secured credit facilities (the “Senior Secured Credit Facilities”), which consist of (i) the senior secured term loan facility, as amended on June 8, 2018, in an original amount of $2,325.0 million (collectively, the “Dollar Term Loan Facility”), (ii) the euro-denominated senior secured term loan facility in an amount equal to €337.4 million (the “Euro Term Loan Facility” and, together with the Dollar Term Loan Facility, the “Term Loan Facilities”), and (iii) the Revolving Credit Facility (as amended, the “Credit Agreement”), and Ortho might not be able to obtain such waivers on reasonable terms, if at all.

Ortho’s ability to obtain additional capital on commercially reasonable terms may be limited or non-existent.

Although Ortho believes its cash, cash equivalents and short-term investments, as well as future cash generated from operations and availability under Ortho’s Revolving Credit Facility, provide adequate resources to fund ongoing debt service and working capital requirements, capital expenditures and transition costs for the foreseeable future, Ortho may need to seek additional financing to compete effectively.

If Ortho is unable to obtain capital on commercially reasonable terms, or at all, it could:

| • |  | result in reduced funds available to Ortho for purposes such as working capital, capital expenditures, research and development, strategic acquisitions and other general corporate purposes;

| • |  | restrict Ortho’s ability to introduce new services or products or exploit business opportunities;

| • |  | increase Ortho’s vulnerability to economic downturns and competitive pressures in the markets in which Ortho operates; and

| • |  | place Ortho at a competitive disadvantage.

Ortho may engage in acquisitions and divestitures, and may encounter difficulties integrating acquired businesses with, or disposing of divested businesses from, Ortho’s current operations; therefore, Ortho may not realize the anticipated benefits of these acquisitions and divestitures.

Ortho may seek to grow through strategic acquisitions. Ortho’s due diligence reviews of Ortho’s acquisition targets may not identify all of the material issues necessary to accurately estimate the cost or potential loss contingencies with respect to a particular transaction, including potential exposure to regulatory sanctions resulting from an acquisition target’s previous activities as well as potential vulnerability to cybersecurity risks. Ortho may incur unanticipated costs or expenses, including post-closing asset impairment charges, expenses associated with eliminating duplicate facilities, litigation and other liabilities. Ortho also may encounter difficulties in integrating acquisitions with Ortho’s operations, applying Ortho’s internal controls processes to these acquisitions, retaining key technical and management personnel, complying with regulatory requirements, or in managing strategic investments. Additionally, Ortho may not achieve the benefits Ortho anticipates when Ortho first enters into a transaction in the amount or timeframe anticipated. Any of the foregoing could adversely affect Ortho’s business and results of operations. In addition, accounting requirements relating to business combinations, including the requirement to expense certain acquisition costs as incurred, may cause Ortho to experience greater earnings volatility and generally lower earnings during periods in which Ortho acquires new businesses. Furthermore, Ortho may make strategic divestitures from time to time. These divestitures may result in continued financial involvement in the divested businesses, such as through guarantees, indemnity obligations or other financial arrangements, following those transactions. Under these arrangements, nonperformance by those divested businesses could result in financial obligations imposed upon Ortho and could affect Ortho’s future financial results.

It may be difficult for Ortho to implement Ortho’s strategies for improving growth.

Ortho plans to continue expanding its commercial capabilities and the scope of its business, both domestically and internationally, while maintaining its commercial operations and administrative activities. For example, Ortho intends to pursue the following growth strategies: (i) maximize Lifetime Customer Value (“LCV”) to produce and maintain a growing and recurring, high margin, durable financial profile; (ii) provide an unparalleled customer experience to retain and attract existing and new customers; (iii) leverage Ortho’s global footprint to deliver innovative solutions to meet Ortho’s customers’ needs in both developed and emerging markets; (iv) create meaningful product innovation through menu expansion, development of novel instruments and enhancement of automation and informatics; (v) continue to identify operating efficiencies to allow for reinvestment in growth and improve margins; and (vi) pursue business development opportunities,

47

partnerships and strategic acquisitions to enter adjacencies or expand Ortho’s current business units. However, Ortho’s ability to manage its business and conduct its global operations while also pursuing the aforementioned growth strategies requires considerable management attention and resources. Furthermore, it is subject to the challenges of supporting a growing business on a global basis.

Ortho’s failure to implement these strategies in a cost-effective and timely manner could have an adverse effect on Ortho’s business, results of operations and financial condition.

Ortho may need to recognize impairment charges related to goodwill, identified intangible assets and fixed assets.

Under the acquisition method of accounting for business combinations, the net assets acquired are recorded at their fair value as of the date of the acquisition, with any excess purchase price recorded as goodwill. Ortho was created pursuant to the acquisition by Ortho-Clinical Diagnostics Bermuda Co. Ltd., a Bermuda exempted limited liability company and direct wholly-owned subsidiary of Ortho, pursuant to a stock and asset purchase agreement, dated January 16, 2014 (the “Acquisition Agreement”), of (i) certain assets and liabilities and (ii) all of the equity interests and substantially all of the assets and liabilities of certain entities which, together with their subsidiaries, comprised the Ortho Clinical Diagnostics business from Johnson & Johnson (the “Acquisition”). The Acquisition resulted in significant balances of goodwill and identified intangible assets. As of January 2, 2022, the balance of goodwill and identified intangible assets was $573.6 million and $879.2 million, respectively. Ortho is required to test goodwill and any other intangible asset with an indefinite life for possible impairment on the same date each year and on an interim basis if there are indicators of a possible impairment. Ortho is also required to evaluate amortizable intangible assets and fixed assets for impairment if there are indicators of a possible impairment.

There is significant judgment required in the analysis of a potential impairment of goodwill, identified intangible assets and fixed assets. If, as a result of a general economic slowdown, deterioration in one or more of the markets in which Ortho operates or impairment in Ortho’s financial performance and/or future outlook, the estimated fair value of Ortho’s long-lived assets decreases, Ortho may determine that one or more of Ortho’s long-lived assets is impaired. An impairment charge would be determined based on the estimated fair value of the assets and any such impairment charge could have a material adverse effect on Ortho’s results of operations and financial position.

Ortho may be unable to achieve some or all of the operational cost improvements and other benefits that Ortho expects to realize.

Ortho has previously announced several initiatives to strengthen its operational performance and has begun to execute certain of these initiatives. For example, Ortho has pursued a number of operational cost improvements associated with procurement, manufacturing, field service organization, distribution and logistics, quality and regulatory and other general and administrative functions. However, Ortho cannot be certain that it will be able to successfully realize all the expected benefits of these initiatives. A variety of risks could cause Ortho not to realize some or all of the expected benefits. These risks include, among others, higher-than-expected standalone overhead expenses, delays in the anticipated timing of activities related to such initiatives, increased difficulty and cost in establishing Ortho as a standalone business and the incurrence of other unexpected costs associated with operating the business. Moreover, Ortho’s continued implementation of these initiatives may disrupt its operations and performance and Ortho’s estimated cost savings from these initiatives are based on several assumptions that may prove to be inaccurate and, as a result, Ortho cannot assure you that it will realize these cost savings. If, for any reason, the benefits Ortho realizes are less than its estimates or if Ortho’s improvement initiatives adversely affect its operations or cost more or take longer to implement than Ortho projects, or if Ortho’s assumptions prove inaccurate, Ortho’s results of operations may be materially adversely affected.

Ortho’s collaboration arrangements may not operate according to its business strategy if its collaboration arrangement partners fail to fulfill their obligations.

As part of Ortho’s business, it has entered into collaboration arrangements with other companies, including the ongoing collaboration with Grifols Diagnostics Solutions, Inc. (the “Joint Business”), which is structured as a license, research and supply agreement, and Ortho may enter into additional collaboration arrangements in the future.

The nature of a collaboration arrangement requires Ortho to share control over significant decisions with unaffiliated third parties. Since Ortho may not exercise exclusive control over its current or future collaboration arrangements, Ortho may not

48

be able to require its collaboration arrangement partners to take actions that Ortho believes are necessary to implement Ortho’s business strategy. Additionally, differences in views among collaboration arrangement partners may result in delayed decisions or failures to agree on major issues. Disputes between Ortho and its collaboration arrangement partners could also result in litigation, which can be expensive and time-consuming. If these differences cause Ortho’s collaboration arrangements to deviate from its business strategy, Ortho’s results of operations could be materially adversely affected.

If Ortho delivers products with defects, Ortho may be subject to product recalls or negative publicity, Ortho’s credibility may be harmed, market acceptance of Ortho’s products may decrease and Ortho may be exposed to liability.

The manufacturing and marketing of professional and consumer diagnostics involve an inherent risk of product liability claims. For example, a defect in one of Ortho’s diagnostic products could lead to a false positive or false negative result, affecting the eventual diagnosis. Ortho’s product development and production are extremely complex and could expose Ortho’s products to defects. Ortho’s Immunohematology business in particular is subject to the risk of product liability claims, as even the slightest inaccuracies in a specimen’s analysis can lead to critical outcomes in the life of a patient, thereby leaving little to no room for error in the precision and accuracy of such testing.

Manufacturing and design defects could lead to recalls (either voluntary or required by the FDA or other government authorities) and could result in the removal of a product from the market. Depending on the corrective action Ortho takes to redress a product’s deficiencies, Ortho may be required to obtain new clearances or approvals before it may market or distribute the corrected device. Defects in Ortho’s products could also harm Ortho’s reputation, lead to negative publicity and decrease sales of Ortho’s products, and Ortho could also face additional regulatory enforcement action, including FDA warning letters, untitled letters, product seizure, injunctions, administrative penalties, or civil or criminal fines.

In addition, Ortho’s marketing of monitoring services may cause Ortho to be subjected to various product liability or other claims, including, among others, claims that inaccurate monitoring results lead to injury or death, or, in the case of Ortho’s toxicology monitoring services, the imposition of criminal sanctions. Any product liability or other claim brought against Ortho, regardless of merit, could be costly to defend and could result in an increase to Ortho’s insurance premiums. If Ortho is held liable for a claim, that claim could materially affect Ortho’s business and financial condition.

A decrease in the number of surgical procedures performed, and the resulting decrease in blood demand, could negatively impact Ortho’s financial results.

Ortho’s Immunohematology and Donor Screening products are frequently used in connection with the testing of blood prior to transfusion, which is typically associated with surgical procedures. A decrease in the number of surgeries being performed in the markets in which Ortho operates could result in decreased demand for blood for transfusions, which would in turn result in lower testing volumes and, therefore, decreased sales of Ortho’s products. For example, Ortho believes the market in developed countries has, at times, seen a decrease in the number of surgical procedures and lower demand for blood in recent years. A decrease in the number of surgical procedures performed could result from a variety of factors, such as fewer elective procedures and the improved efficacy and popularity of non-surgical treatments. In addition to lower surgical volumes, blood demand could also be negatively affected by more efficient blood utilization by hospitals. Blood is a large expense for hospital laboratories and pressure on hospital budgets due to macroeconomic factors and healthcare reform could force changes in the ways in which blood is used. Fewer surgeries and lower blood demand could negatively impact Ortho’s revenue, profitability and cash flows.

Ortho’s reagent rental model reduces Ortho’s cash flows during the initial part of the applicable contract, which causes Ortho’s cash flows to fluctuate from quarter to quarter.

Leases, rather than sales, of instruments under Ortho’s reagent rental model have the effect of reducing cash flows during the initial part of the applicable contract as Ortho supports those commercial transactions until Ortho is able to recover its investment over the life of the contract. The use of cash in connection with this model causes Ortho’s cash flows to fluctuate from quarter to quarter and may have a negative effect on Ortho’s financial condition.

Johnson & Johnson’s historical and future actions, or failure to comply with its indemnification obligations, may materially affect Ortho’s business and operating results.

Although Ortho is an independent company as a result of the Acquisition, Johnson & Johnson’s historical and future actions may still have a material impact on Ortho’s business and operating results. In connection with the Acquisition, Ortho entered

49

into certain agreements with Johnson & Johnson, including the Acquisition Agreement and certain other transitional services agreements. In addition, Johnson & Johnson has, subject to certain exceptions and exclusions, agreed to indemnify Ortho under the Acquisition Agreement for certain liabilities relating to historical litigation matters and divestiture agreements, tax liabilities existing at the date of the Acquisition and certain employee-related liabilities. Ortho could incur material additional costs if Johnson & Johnson fails to meet its obligations or if Ortho otherwise is unable to recover costs associated with such liabilities.

Risks Relating to Ortho’s International Operations

As a global business, Ortho is subject to risks associated with Ortho’s non-U.S. operations where such risks are not present in the United States.

Ortho conducts its business on a global basis, with sales outside the United States constituting approximately 50.3% of Ortho’s total revenue for the fiscal year ended January 2, 2022, and a significant number of employees and contractors located in foreign countries. Ortho anticipates that international sales will continue to represent a substantial portion of Ortho’s revenue and that Ortho’s strategy for continued growth and profitability will entail further international expansion, particularly in emerging markets. Conducting business outside the United States subjects Ortho to numerous risks, including:

| • |  | lost revenue as a result of macroeconomic developments;

| • |  | decreased liquidity resulting from longer accounts receivable collection cycles typical of foreign countries;

| • |  | lower productivity resulting from difficulties Ortho encounters in staffing and managing sales, support and research and development operations across many countries;

| • |  | difficulties associated with enforcing agreements and collecting receivables through foreign legal systems;

| • |  | disputes with third-party distributors of Ortho’s products or from third parties claiming distribution rights to Ortho’s products;

| • |  | difficulties associated with navigating foreign laws and legal systems;

| • |  | difficulties in identifying potential third-party distributors or distribution channels;

| • |  | the imposition by foreign governments of trade barriers such as tariffs, quotas, preferential bidding and import restrictions;

| • |  | import or export licensing requirements, both by the United States and foreign countries;

| • |  | acts of war, terrorism, theft or other lawless conduct or other economic, social or political instability in or affecting foreign countries in which Ortho sells its products or operates;

| • |  | international sanctions regimes;

| • |  | adverse effects resulting from changes in foreign regulations, rules, policies or other laws affecting sales of Ortho’s products or Ortho’s foreign operations;

| • |  | tax liability resulting from international tax laws;

| • |  | increased financial accounting and reporting burdens and complexities;

| • |  | increased costs to comply with changes in legislative or regulatory requirements;

| • |  | failure of laws to protect Ortho’s intellectual property rights; and

| • |  | delays in obtaining import or export licenses, transportation difficulties and delays resulting from inadequate local infrastructure.

The occurrence of any of these, or other factors over which Ortho does not have control, could lead to reduced revenue and profitability.

Currency translation risk and currency transaction risk may adversely affect Ortho’s financial condition, results of operations and cash flows.

Ortho derives a significant portion of its revenue from outside the United States (approximately 50.3% for the fiscal year ended January 2, 2022), and Ortho conducts its business and incurs costs in the local currency of most countries in which it

50

operates. Because Ortho’s financial statements are presented in U.S. dollars, Ortho must translate earnings as well as assets and liabilities into U.S. dollars at exchange rates in effect during or at the end of each reporting period, as applicable. Therefore, increases or decreases in the value of the U.S. dollar against other currencies in countries where Ortho operates will affect Ortho’s results of operations and the value of balance sheet items denominated in foreign currencies. Furthermore, many of Ortho’s local businesses generate revenues and incur costs in a currency other than their functional currency, which can impact the operating results for these operations if Ortho is unable to mitigate the impact of foreign currency fluctuations. Additionally, in order to fund the purchase price for certain assets of Ortho and the capital stock of certain other non-U.S. entities, a combination of equity contributions and intercompany loans were utilized to capitalize certain non-U.S. subsidiaries. In many instances, the intercompany loans are denominated in currencies other than the functional currency of the affected subsidiaries. Where intercompany loans are not a component of permanently invested capital of the affected subsidiaries, increases or decreases in the value of the subsidiaries’ functional currency against other currencies will affect Ortho’s results of operations. Ortho cannot accurately predict the effects of exchange rate fluctuations upon its future operating results because of the number of currencies involved, the variability of currency exposures and the potential volatility of currency exchange rates. Accordingly, Ortho’s profitability could be affected by fluctuations in foreign exchange rates. Given the volatility of exchange rates, Ortho may not be able to effectively manage its currency transaction and/or translation risks, and any volatility in currency exchange rates may have an adverse effect on Ortho’s financial condition, results of operations and cash flows. Ortho has entered into hedging agreements to address certain of its currency risks and intends to utilize local currency funding of expansions when appropriate. Ortho does not intend to hold financial instruments for trading or speculative purposes.

New tariffs and other trade measures could adversely affect Ortho’s business and financial results.

Governments sometimes impose additional duties, tariffs or taxes on certain imported products. The imposition of import tariffs or restrictions, or other changes in U.S. trade policy, could trigger retaliatory actions by affected countries. For instance, the United States and China have implemented import tariffs and retaliatory tariffs on certain categories of goods, including from time to time, some of Ortho’s reagent products sold in China. These tariffs, depending upon their ultimate scope and value and how they are implemented, could negatively impact Ortho’s business by increasing Ortho’s costs and by making Ortho’s products less cost competitive in China.

The United Kingdom’s withdrawal from the European Union may have a negative effect on global economic conditions, financial markets and Ortho’s business.

Ortho is a multinational company with worldwide operations, including significant business operations in Europe. Following a national referendum in which a majority of voters in the United Kingdom elected to withdraw from the European Union and the enactment of legislation by the government of the United Kingdom, the United Kingdom formally withdrew from the European Union on January 31, 2020. On December 24, 2020, the United Kingdom and the European Commission reached an agreement on the terms of its future cooperation with the European Union (the “UK-EU Trade and Cooperation Agreement”). On December 30, 2020, the UK Parliament provided its approval of the European Union (Future Relationship) Bill (now the European Union (Future Relationships) Act 2020) which implements, inter alia, the UK-EU Trade and Cooperation Agreement. However, significant political and economic uncertainty remains about whether the terms of the relationship will differ materially in practice from the terms before withdrawal and uncertainty continues to persist as there are a number of areas not covered by the UK-EU Trade and Cooperation Agreement.

These developments, or the perception that any of them could occur, have had and may continue to have a material adverse effect on global economic conditions and the stability of global financial markets, and could significantly reduce global market liquidity and restrict the ability of key market participants to operate in certain financial markets. The medium- and long-term impact of withdrawal of the United Kingdom from the European Union on these conditions and markets are not yet known. Asset valuations, currency exchange rates and credit ratings have been and may continue to be subject to increased market volatility. Lack of clarity about future United Kingdom laws and regulations as the United Kingdom determines which European Union laws to replace or replicate could depress economic activity and investment into the United Kingdom and restrict Ortho’s access to capital. The full extent of the tax implications of the United Kingdom’s departure from the European Union are also not certain as of the date of this joint proxy statement/prospectus.

In addition, there is a risk of delays in the delivery of Ortho’s products from the United Kingdom to customers in the European Union and an increase in associated delivery costs. Restrictions on the free movement of goods (including as a result of customers’ duties, import tariffs or other restrictions on trade) could also have a material adverse effect on Ortho’s

51

supply chains, production schedule and costs. In addition, Ortho may face challenges retaining or attracting EU staff in the United Kingdom, which could disrupt its business and growth in this market. The full impact of the changes to immigration laws following the United Kingdom’s departure from the European Union is not clear, but Ortho may face particular challenges attracting skilled talent (including scientists, engineers and laboratory technicians) if the conditions for EU nationals to be eligible to work in the United Kingdom are found, or are perceived, to be more onerous or expensive.

It is also possible that the resulting uncertainty and/or economic instability in the UK outlined above, could have a wider effect in other countries, for instance as a result of spreading economic market conditions or if other European Union member states are also prompted to leave.

Any of these factors could have a material adverse effect on Ortho’s business, financial condition and results of operations and prospects.

Risks Relating to Ortho’s Employees, Customers and Suppliers

Ortho must deliver products and services that meet customers’ needs and expectations or Ortho’s business and results of operations will be adversely impacted.

Ortho’s ability to retain customers, attract new customers, grow Ortho’s business and enhance its brand depends on Ortho’s success in delivering products and services that meet its customers’ needs and expectations. If Ortho is unable to deliver reliable products in a timely manner, promptly respond to and address quality issues, provide expected levels of customer service, develop and maintain cross-functional communication within Ortho’s company and comply with applicable regulations and rules, Ortho’s ability to deliver products that meet its customers’ needs and expectations, its competitive position, branding and results of operations may be adversely and materially affected. Furthermore, any improvement in the perception of the quality of Ortho’s competitors’ products or services relative to the quality of Ortho’s products and services could adversely and materially affect Ortho’s ability to retain Ortho’s customers and attract new customers. Additionally, the introduction of counterfeit products into the markets Ortho serves may have the effect of eroding confidence in Ortho’s products or in Ortho’s industry as a whole.

The success of many of Ortho’s products depends heavily on acceptance by directors of clinical laboratories, blood banks and hospitals, and Ortho’s failure to maintain a high level of confidence in its products could adversely affect its business.

Ortho maintains customer relationships with numerous directors of clinical laboratories, blood banks and hospitals. Ortho believes that sales of its products depend significantly on its customers’ confidence in, and recommendations of, its products. In addition, Ortho’s success depends on technicians’ acceptance and confidence in the effectiveness and ease-of-use of Ortho’s products, including its new products. In order to achieve acceptance by healthcare professionals, Ortho seeks to educate the healthcare community as to the distinctive characteristics, perceived benefits, clinical efficacy and cost-effectiveness of Ortho’s products compared to alternative products, including the products offered by its competitors. Acceptance of Ortho’s products also requires effective training of healthcare professionals in the proper use and application of Ortho’s products. Failure to effectively educate and train Ortho’s technician end-users and failure to continue to develop relationships with leading healthcare professionals could result in less frequent recommendations of Ortho’s products, which may adversely affect Ortho’s sales and profitability.

The healthcare industry and related industries that Ortho serves have undergone, and are in the process of undergoing, significant changes in an effort to reduce costs, which could adversely affect Ortho’s business, financial condition and results of operations.

The healthcare industry and related industries that Ortho serves have undergone, and are in the process of undergoing, significant changes in an effort to reduce costs.

Many of Ortho’s customers, and the end-customers to whom Ortho’s customers supply products, rely on government funding of and reimbursement for healthcare products and services and research activities. The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act (collectively, the “PPACA”), healthcare austerity measures in Europe and other potential healthcare reform changes and government austerity measures may reduce the amount of government funding or reimbursement available to customers or end-customers of Ortho’s products and services and/or the volume of medical procedures using Ortho’s products and services. Global economic uncertainty or deterioration can also adversely impact government funding and reimbursement.

52

Governmental and private healthcare providers and payors around the world are increasingly utilizing managed care for the delivery of healthcare services, forming group purchasing organizations to improve their purchasing leverage and using competitive bid processes to procure healthcare products and services.

Health insurance premiums, co-payments and deductibles have also generally increased in recent years. These increases may cause individuals to forgo health insurance, as well as medical attention. This behavior may reduce the number of lives managed by Ortho’s health information solutions, including Ortho’s health improvement programs.

These changes have increased tax costs and may cause participants in the healthcare industry to purchase fewer of Ortho’s products and services, reduce the prices they are willing to pay for Ortho’s products or services, reduce the amounts of reimbursement and funding available for Ortho’s products or services from governmental agencies or third-party payors, reduce the volume of medical procedures that use Ortho’s products and services and increase Ortho’s compliance and other costs. In addition, Ortho may be unable to enter into contracts with group purchasing organizations and integrated health networks on terms acceptable to Ortho, and even if Ortho does enter into such contracts, they may be on terms that negatively affect its current or future profitability.

All of the factors described above could adversely affect Ortho’s business, financial condition and results of operations.

Reductions in government funding and reimbursement to Ortho’s customers could negatively impact Ortho’s sales and results of operations.

Many of Ortho’s customers rely on government funding and on prompt and full reimbursement by Medicare and Medicaid and equivalent programs outside of the United States. Global economic uncertainty can result in lower levels of government funding or reimbursement. A reduction in the amount or types of government funding or reimbursement that affect Ortho’s customers could have a negative impact on Ortho’s sales. Additionally, the PPACA, which was enacted in 2010, substantially changed the way healthcare is financed by both governmental and private insurers in the United States and expanded Medicaid program eligibility and access to commercial health insurance coverage. Since its enactment, there have been judicial, executive and Congressional challenges to certain aspects of the PPACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the PPACA brought by several states without specifically ruling on the constitutionality of the PPACA. Prior to the Supreme Court’s decision, President Biden issued an executive order to initiate a special enrollment period for purposes of obtaining health insurance coverage through the PPACA marketplace, from February 15, 2021 through August 15, 2021. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including, among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the PPACA. It is unclear how other healthcare reform measures of the Biden administration or other efforts, if any, to challenge, repeal or replace the PPACA will impact the law or our business.

In addition, other legislative changes have been proposed and adopted since the PPACA was enacted. The Budget Control Act of 2011, among other things, reduced Medicare payments to providers by 2% per fiscal year, effective on April 1, 2013 and, due to subsequent legislative amendments to the statute, will remain in effect through 2030, with the exception of a temporary suspension from May 1, 2020, through March 31, 2022, unless additional Congressional action is taken. Additionally, the American Taxpayer Relief Act of 2012, among other things, further reduced Medicare payments to several providers, including hospitals, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. The Medicare Access and CHIP Reauthorization Act of 2015 (“MACRA”), enacted on April 16, 2015, repealed the formula by which Medicare made annual payment adjustments to physicians and replaced the former formula with fixed annual updates and a new system of incentive payments that are based on various performance measures and physicians’ participation in alternative payment models such as accountable care organizations. It is unclear what effect new quality and payment programs, such as MACRA, may have on our business, financial condition, results of operations or cash flows.

On January 1, 2018, CMS implemented certain provisions of the Protecting Access to Medicare Act of 2014 (“PAMA”), which made substantial changes to the way in which clinical laboratory services are paid under Medicare. Under PAMA, laboratories that receive the majority of their Medicare revenue from payments made under the CLFS or the Physician Fee Schedule are required to report to CMS, beginning in 2017 and every three years thereafter (or annually for “advanced diagnostics laboratory tests”), private payer payment rates and volumes for their tests. Laboratories that fail to report the

53

required payment information may be subject to substantial civil monetary penalties. CMS uses the data to calculate a weighted median payment rate for each test, which is used to establish a revised Medicare reimbursement rate. Under PAMA, the revised Medicare reimbursement rates were scheduled to apply to clinical diagnostic laboratory tests furnished on or after January 1, 2018. The revised reimbursement methodology is expected to result in relatively lower reimbursement under Medicare for clinical diagnostic lab tests than has been historically available. Any reduction to payment rates resulting from the new methodology is limited to 10% per test per year in 2018 through 2020, and to 15% per test per year in 2021 through 2023. For clinical diagnostic laboratory tests that are assigned a new or substantially revised Healthcare Common Procedure Coding System code, initial payment rates for clinical diagnostic laboratory tests that are not advanced diagnostic laboratory tests will be assigned by the cross-walk or gap-fill methodology. Initial payment rates for new advanced diagnostic laboratory tests will be based on the actual list charge for the laboratory test. The Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”), which was signed into law on March 27, 2020, amended the timeline for reporting private payer payment rates, and delayed by one year the payment reductions scheduled for 2021. On December 10, 2021, Congress passed the Protecting Medicare and American Farmers from Sequester Cuts Act (“PMAFSA”), which delays the next data-reporting period by an additional year and prevents any reduction in payment amounts from commercial payer rate implementation in 2022.

In addition to the CARES Act, Congress has enacted other laws in response to the COVID-19 pandemic to provide financial relief to healthcare providers and suppliers, including diagnostic laboratories, and to encourage implementation of diagnostic testing and treatment for COVID-19. For instance, the Families First Coronavirus Response Act (“FFCRA”), enacted on March 18, 2020, requires certain governmental and commercial insurance plans to provide coverage of COVID-19 diagnostic testing services without imposing cost-sharing (e.g., copays, deductibles or coinsurance) or other utilization management requirements. The CARES Act and the Paycheck Protection Program and Health Care Enhancement Act (“PPPHCEA”), enacted on April 24, 2020, each appropriated approximately $100 billion to provide financial relief for certain healthcare providers and to expand treatment and diagnostic testing capacity for COVID-19. The Consolidated Appropriations Act of 2021 (“CAA”), which was enacted on December 27, 2020 and included further pandemic relief measures, temporarily increased payment rates under the Medicare Physician Fee Schedule by 3.75% beginning January 1, 2021 through December 31, 2021. The PMAFSA further established a temporary 3% payment rate increase under the Medicare Physician Fee Schedule that will remain in effect beginning January 1, 2022 through December 31, 2022. The CARES Act, as subsequently amended by the CAA and PMAFSA, also suspended, for the period from May 1, 2020 to March 31, 2022, the 2% payment reduction created under the sequestration required by the Budget Control Act of 2011 (as amended by the American Taxpayer Relief Act of 2012), and extended the sequester by one year, through 2030.

It is unclear what impact new quality and payment programs, such as MACRA, or new pricing structures, such as those adopted under PAMA, the CARES Act, or other legislative measures enacted in response to the COVID-19 pandemic, may have on Ortho’s business, financial condition, results of operations or cash flows.

Ortho relies on certain suppliers and manufacturers for raw materials and components for Ortho’s products and services, and fluctuations in the availability and price of such materials, products and services may interfere with Ortho’s ability to meet Ortho’s customers’ needs.

For certain of Ortho’s products, including finished products, Ortho is dependent on a small number of key suppliers and manufacturers. Ortho also depends on key suppliers for critical raw materials and components. As a result, Ortho’s ability to obtain, enter into and maintain contracts with these manufacturers and suppliers is important to Ortho’s business. Ortho cannot ensure that it will be able to obtain, enter into or maintain all such contracts in the future, and difficulty in obtaining such products or raw materials could affect Ortho’s ability to achieve anticipated production levels. On occasion, Ortho has been forced to revalidate the raw materials and components of products when a supplier of critical raw materials or components terminated its contract or no longer made the materials or components available to Ortho. Stringent requirements of the FDA and other regulatory authorities regarding the manufacture of Ortho’s products may prevent Ortho from quickly establishing additional or replacement sources for the raw materials, products, components or manufacturing services that Ortho uses, or from doing so without excessive cost. Further, Ortho’s suppliers may be subject to regulation by the FDA and other regulatory authorities that could hinder their ability to produce necessary raw materials, products and components. As a result, a reduction or interruption in supply or an inability to secure alternative sources of raw materials, products, components or manufacturing services could have a material adverse effect on Ortho’s business, result of operations, financial condition and cash flows. If Ortho is unable to achieve anticipated production levels and meet Ortho’s customers’ needs, Ortho’s operating results could be adversely affected. For a discussion of the impact of global supply chain challenges on Ortho, including on Ortho’s ability to obtain certain key components of its instruments and fulfill customer orders on a

54

timely basis, see “—Ortho has significant international sales and operations and faces risks related to health epidemics, including the ongoing global pandemic related to COVID-19. Ortho’s business, consolidated results of operations, financial position and cash flows have been and may continue to be negatively affected by the COVID-19 pandemic.” In addition, Ortho’s results of operations may be significantly impacted by unanticipated increases in the cost of labor, raw materials, freight, utilities and other items needed to develop, manufacture and maintain Ortho’s products and operate Ortho’s business. For example, Ortho may be disadvantaged when negotiating contract terms with its suppliers, which could increase costs and reduce its margins. Suppliers may also deliver products, components or materials that do not meet specifications, preventing Ortho from manufacturing or supplying products that meet Ortho’s design specifications or customer needs.

Ortho may not be able to recruit and retain the experienced and skilled personnel it needs to compete.

Ortho’s future success depends on its ability to attract, retain, develop and motivate highly skilled personnel. Ortho relies on qualified managers and skilled employees, such as scientists, engineers and laboratory technicians, with technical expertise in operations, scientific knowledge, engineering and quality management experience in order to operate Ortho’s business successfully. From time to time, there may be a shortage of skilled labor, which may make it more difficult and expensive for Ortho to attract and retain qualified employees. If Ortho is unable to attract and retain sufficient numbers of qualified individuals or Ortho’s costs to do so increase significantly, Ortho’s operations could be materially adversely affected. Additionally, if Ortho were to lose a sufficient number of its research and development scientists and were unable to replace them or satisfy its needs for research and development through outsourcing, it could adversely affect Ortho’s business.

The loss of key members of management and the risks inherent in succession planning could adversely affect Ortho’s results of operations or financial condition.

Ortho must have talented personnel to succeed and competition for senior management in Ortho’s industry is intense. Ortho’s ability to meet its performance goals depends upon the personal efforts and abilities of the principal members of Ortho’s senior management who provide strategic direction, develop Ortho’s business, manage Ortho’s operations and maintain a cohesive and stable work environment and upon their ability to work effectively as a team.

As part of their ongoing effort to maximize Ortho’s performance, Ortho’s board of directors regularly evaluates Ortho’s senior management capabilities in light of, among other things, Ortho’s business strategy, changes to Ortho’s capital structure, developments in Ortho’s industry and markets and Ortho’s ongoing financial performance, and will consider, where appropriate, supplementing, changing or otherwise enhancing Ortho’s senior management team and operational and financial management capabilities in order to maximize Ortho’s performance. Accordingly, Ortho’s organizational structure and senior management team may change in the future, which could result in a material business interruption, the risk of employment-related claims or proceedings, and the incurrence of material costs, including as a result of severance or other termination payments, damages or other compensation. Further, Ortho cannot assure you that it will retain or successfully recruit senior executives, or that their services will remain available to Ortho.

Consolidation of Ortho’s customer base and the formation of group purchasing organizations could materially adversely affect Ortho’s sales and results of operations.

Consolidation among healthcare providers and the formation of buying groups and, with respect to Ortho’s international operations, government-sponsored tendering processes, have put pressure on pricing and sales of Ortho’s products, and in some instances, required payment of fees to group purchasing organizations or providing lower pricing in the tendering process. Ortho’s success in these areas depends partly on Ortho’s ability to enter into contracts with integrated health networks and group purchasing organizations. If Ortho is unable to enter into contracts with these group purchasing organizations and integrated health networks on terms acceptable to Ortho or fails to have its pricing terms accepted in the tendering process, Ortho’s sales and results of operations may be adversely affected. Even if Ortho is able to enter into these contracts or have its pricing terms accepted in the tendering process, they may be on terms that negatively affect Ortho’s current or future profitability. Furthermore, given the average industry contract length of five to seven years, if Ortho is unable to enter into a contract with a new customer or renew a given contract with an existing customer, it may be several years before Ortho has an opportunity to acquire or reacquire, as applicable, such customer’s business, which may have a material adverse effect on Ortho’s results of operations in the interim period.

55

Ortho may experience manufacturing or warehousing problems or delays due to, among other reasons, Ortho’s volume and specialized processes, and any interruption in supply from certain of its contract manufacturers, suppliers of raw materials and other third-party vendors, which could result in decreased revenue or increased costs.

The global supply of Ortho’s products depends on the uninterrupted efficient operation of its manufacturing facilities, and the continued performance of Ortho’s contract manufacturers, suppliers of raw materials and other third-party vendors under Ortho’s contractual arrangements. Many of Ortho’s manufacturing processes are complex and involve sensitive scientific processes involving the use of unique and often proprietary antibodies and other raw materials that cannot be replicated or acquired through alternative sources without undue delay or expense. Other processes present difficult technical challenges to obtain the manufacturing yields necessary to operate profitably. In addition, Ortho’s manufacturing processes may require complex and specialized equipment, which can be expensive to repair or replace with required lead times of up to a year.

The manufacturing of certain of Ortho’s products is concentrated in one or more of Ortho’s plants, with limited alternate facilities. Any event that negatively impacts Ortho’s manufacturing facilities, Ortho’s manufacturing systems or equipment, or the facilities, systems or equipment of Ortho’s contract manufacturers or suppliers, could delay or suspend shipments of products or the release of new products or could result in the delivery of inferior products. Ortho’s revenue from the affected products would decline and Ortho could incur losses until such time as Ortho or its contract manufacturers are able to restore Ortho’s or their production processes or Ortho is able to put in place alternative contract manufacturers or suppliers. Similarly, given the specialized storage requirements for Ortho’s supplies and Ortho’s products, any disruption or other operational challenges to one of Ortho’s two primary warehouse facilities in Memphis, Tennessee and Strasbourg, France could result in decreased revenue or increased costs given the challenge in finding suitable alternative facilities. As a result of, among other factors, the impact of COVID-19 on supply chain operations as well as increased customer demand for Ortho’s products, Ortho is currently encountering, and may continue to encounter, increased customer backlogs of inventory shipments out of its warehouse facilities, particularly the Memphis, Tennessee facility. If these increased customer backlogs continue, they may adversely impact customer relationships and affect Ortho’s financial performance.

Ortho also relies on contract manufacturers to manufacture certain of its products, such as the instruments for Ortho’s Transfusion Medicine and Clinical Laboratories businesses, as well as suppliers of raw materials and other third-party vendors. Any change in Ortho’s relationship with its contract manufacturers, suppliers of raw materials and other third-party vendors or changes to contractual terms of Ortho’s agreements with any of them could adversely affect Ortho’s financial condition and results of operations. Ortho’s reliance on a small number of contract manufacturers and a large number of single and sole source suppliers makes Ortho vulnerable to possible capacity constraints, reduced control over product availability, delivery schedules and costs and reduced ability to monitor compliance with Ortho’s product manufacturing specifications.

If Ortho’s current contract manufacturers, suppliers of raw materials and other third-party vendors were unable or unwilling to manufacture or supply Ortho’s products or requirements for raw materials in required volumes and at required quality levels or renew existing terms under supply agreements, Ortho may be required to replace such manufacturers, suppliers and vendors and may be unable to do so in a timely or cost-effective manner, or at all. Any interruption of supply or any increase in price of the instruments or raw materials and other key products produced by such contract manufacturers or raw materials supplied by such suppliers and vendors could adversely affect Ortho’s profitability.

Risks Relating to Ortho’s Business—Government Regulation

If Ortho is unable to obtain required clearances or approvals for the commercialization of its products in the United States, Ortho would not be able to sell those products in the United States.

Ortho’s future performance depends on, among other matters, the timely receipt of necessary regulatory clearances and approvals for its products. Regulatory clearance and approval can be a lengthy, expensive and uncertain process. In addition, regulatory processes are subject to change, and new or changed regulations can result in increased costs and unanticipated delays.

In the United States, clearance or approval to commercially distribute new medical devices is received from the FDA through clearance of a Premarket Notification under Section 510(k) of the Federal Food, Drug, and Cosmetic Act (a “510(k)”), or through approval of a Premarket Approval application (a “PMA”). Approval to commercially distribute biologics is received from the FDA through approval of a Biologics License Application (a “BLA”) and may also require state licensing for the movement of biologics products in interstate commerce. The FDA may deny 510(k) clearance because, among other reasons, it determines that Ortho’s product is not substantially equivalent to another U.S. legally marketed device. The FDA may deny

56

approval of a PMA or BLA because, among other reasons, it determines that Ortho’s product is not sufficiently safe or effective. Failure to obtain FDA clearance or approval would preclude commercialization in the United States, which could materially and adversely affect Ortho’s future results of operations.

Modifications or enhancements to a cleared or approved product that could significantly affect safety or effectiveness, or that constitute a major change in the intended use of the product, could require new 510(k) clearances or possibly approval of a new PMA or BLA, or a supplement to those applications. The FDA requires every manufacturer to make the determination regarding the need for a new 510(k) submission in the first instance, but the FDA may review a manufacturer’s decision not to seek a new 510(k). Ortho has made modifications to some of its products since receipt of initial 510(k) clearance. With respect to several of these modifications, Ortho filed new 510(k)s or PMAs; however, Ortho determined that submission was not necessary for all of the modifications. The FDA may not agree with any of Ortho’s determinations not to submit a new 510(k), PMA or PMA supplement, or BLA or BLA supplement for any modifications made to Ortho’s products. If the FDA requires Ortho to submit a new 510(k), PMA or PMA supplement, or BLA or BLA supplement for any product modification, Ortho may be prohibited from marketing the modified products until the new submission is cleared or approved by the FDA. In that case, Ortho may be required to recall and stop marketing its products as modified, which could require Ortho to redesign its products and conduct clinical studies to support any modifications, and Ortho could be subject to enforcement action.

If the results of clinical studies required to gain regulatory approval to sell Ortho’s products are not available when expected, or do not demonstrate the safety and effectiveness of those products, Ortho may be unable to sell those products.

Before Ortho can sell certain of its products, Ortho must conduct clinical studies intended to demonstrate that those products are safe and effective and perform as expected. The results of these clinical studies (which are experiments involving human patients having the diseases or medical conditions that the product is trying to evaluate or diagnose) are used to obtain regulatory clearance or approval from government authorities, such as the FDA. Conducting clinical studies is a complex, time-consuming and expensive process. In some cases, Ortho may spend several years completing the necessary clinical studies.

If Ortho fails to adequately manage its clinical studies, those clinical studies and corresponding regulatory clearances or approvals may be delayed or Ortho may fail to gain clearance or approval for its products altogether. Even if Ortho successfully manages its clinical studies, Ortho may not obtain favorable results and may not obtain regulatory clearance or approval. If Ortho is unable to market and sell its new products or is unable to obtain clearances or approvals in the time frame needed to execute its product strategies, Ortho’s business and results of operations would be materially and adversely affected.

Ortho is subject to the regulatory approval requirements of the foreign countries in which it sells its products, and these requirements may prevent or delay Ortho from marketing its products in those countries.

Ortho is subject to the regulatory approval requirements for each foreign country in which it sells its products. The process for complying with these approval requirements can be lengthy and expensive. Any changes in foreign approval requirements and processes may cause Ortho to incur additional costs or lengthen review times of Ortho’s products. Ortho may not be able to obtain foreign regulatory approvals on a timely basis, if at all, and any failure to do so may cause Ortho to incur additional costs or prevent it from marketing its products in foreign countries, which may have a material adverse effect on Ortho’s business, financial condition and results of operations.

Ortho’s business is subject to substantial regulatory oversight, and Ortho’s failure to comply with applicable regulations may result in significant costs or, in certain circumstances, the suspension or withdrawal of previously obtained clearances or approvals.

Ortho’s businesses are extensively regulated by the FDA and other federal, state and foreign regulatory agencies. These regulations impact many aspects of Ortho’s operations, including development, manufacturing, labeling, packaging, adverse event reporting, storage, advertising, promotion, physician interaction and record-keeping. Any material failure by Ortho to comply with such applicable governmental regulations could result in product recalls, the imposition of fines, restrictions on Ortho’s ability to conduct or expand its operations or the cessation of all or a portion of its operations.

The FDA and corresponding foreign regulatory agencies may require post-market testing and surveillance to monitor the performance of cleared or approved products or may place conditions on any product clearances or approvals that could

57

restrict the commercial applications of those products. The discovery of problems with a product may result in restrictions on the product, including withdrawal of the product from the market. In addition, in some cases Ortho may sell products or provide services which are reliant on the use or commercial availability of products of third parties, including medical devices or equipment, and regulatory restrictions placed upon any such third-party products could have a material adverse impact on the sales or commercial viability of Ortho’s related products or services.

Ortho is subject to routine inspection by the FDA and other agencies for compliance with the FDA’s requirements applicable to Ortho’s products, including, without limitation, the Quality System Regulation and Medical Device Reporting requirements in the United States, and other applicable regulations worldwide. Ortho’s manufacturing facilities and those of its suppliers and distributors also are, or can be, subject to periodic regulatory inspections.

Ortho is also subject to laws relating to matters such as privacy, safe working conditions, manufacturing practices, environmental protection, fire hazard control and disposal of hazardous or potentially hazardous substances. Ortho may incur significant costs to comply with these laws and regulations. If Ortho fails to comply with applicable regulatory requirements, Ortho may be subject to fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products or injunctions against Ortho’s distribution of products, termination of Ortho’s service agreements by its customers, disgorgement of money, operating restrictions and criminal prosecution.

Changes in applicable laws, changes in the interpretation or application of such laws, or any failure to comply with existing or future laws, regulations or standards could have a material adverse effect on Ortho’s results of operations, financial condition, business and prospects. Moreover, new laws may be enacted, or regulatory agencies may impose new or enhanced standards, that would increase Ortho’s costs, as well as expose Ortho to risks associated with non-compliance. Over the last several years, the FDA has proposed reforms to its 510(k) clearance process, and such proposals could include increased requirements for clinical data and a longer review period, or could make it more difficult for manufacturers to utilize the 510(k) clearance process for their products. For example, in November 2018, FDA officials announced steps that the FDA intended to take to modernize the premarket notification pathway under Section 510(k) of the Federal Food, Drug, and Cosmetic Act. Among other things, the FDA announced that it planned to develop proposals to drive manufacturers utilizing the 510(k) pathway toward the use of newer predicates. These proposals included plans to potentially sunset certain older devices that were used as predicates under the 510(k) clearance pathway, and to potentially publish a list of devices that have been cleared on the basis of demonstrated substantial equivalence to predicate devices that are more than ten years old. These proposals have not yet been finalized or adopted, although the FDA may work with Congress to implement such proposals through legislation. Accordingly, it is unclear the extent to which any proposals, if adopted, could impose additional regulatory requirements on Ortho that could delay its ability to obtain new 510(k) clearances, increase the costs of compliance, restrict Ortho’s ability to maintain its current clearances, or otherwise create competition that may negatively affect its business.

More recently, in September 2019, the FDA issued revised final guidance describing an optional “safety and performance based” premarket review pathway for manufacturers of “certain, well-understood device types” to demonstrate substantial equivalence under the 510(k) clearance pathway by showing that such device meets objective safety and performance criteria established by the FDA, thereby obviating the need for manufacturers to compare the safety and performance of their medical devices to specific predicate devices in the clearance process. The FDA maintains a list of device types appropriate for the “safety and performance based” pathway and continues to develop product-specific guidance documents that identify the performance criteria for each such device type, as well as recommended testing methods, where feasible. The FDA may establish performance criteria for classes of devices for which Ortho or its competitors seek or currently have received clearance, and it is unclear the extent to which such performance standards, if established, could impact Ortho’s ability to obtain new 510(k) clearances or otherwise create competition that may negatively affect Ortho’s business.

Ortho is subject to extensive regulatory requirements in connection with the emergency use authorizations (“EUAs”) that Ortho has received from the FDA for its COVID-19 antibody and antigen tests. If Ortho fails to comply with these requirements, or if the FDA otherwise determines that the conditions no longer warrant such authorization, Ortho will be unable to market its products pursuant to this authorization and its business may be harmed.

Ortho has received EUAs from the FDA authorizing Ortho to market its Anti-SARS-CoV-2 IgG Antibody test, Anti-SARS-CoV-2 IgG Quantitative Antibody test, Anti-SARS-CoV-2 Total (Anti-S) Antibody test, Anti-SARS-CoV-2 Total (Anti-N) Antibody test, SARS-CoV-2 Antigen test and related calibrators and controls on Ortho’s VITROS analyzers. These EUAs allow Ortho to market and sell its antibody tests to health-care professionals for the detection of certain SARS-CoV-2

58

antibodies to aid in identifying individuals with an adaptive immune response to SARS-CoV-2 and, for Ortho’s Antigen test, for the detection of acute infection of SARS-CoV-2, without the need to obtain premarket clearance or approval under the FDA’s standard review pathways, for the duration of the COVID-19 public health emergency. The FDA has also established certain conditions which must be met in order to maintain authorization under these EUAs. The requirements that apply to the manufacture and sale of these products may be unclear and are subject to change.

The FDA has the authority to issue an EUA during a public health emergency if it determines that, based on the totality of the scientific evidence, it is reasonable to believe that the product may be effective, that the known and potential benefits of a product outweigh the known and potential risks, that there is no adequate, approved and available alternative and if other regulatory criteria are met. These standards for marketing authorization are lower than if the FDA had reviewed Ortho’s tests under its traditional marketing authorization pathways, and Ortho cannot assure you that its tests would be cleared or approved under those more onerous clearance and approval standards. Moreover, the FDA’s policies regarding EUAs can change unexpectedly, and the FDA may revoke an EUA where it determines that the underlying health emergency no longer exists or warrants such authorization or if problems are identified with the authorized product. Ortho cannot predict how long its authorization will remain in place. FDA policies regarding diagnostic tests, therapies and other products used to diagnose, treat or mitigate COVID-19 remain in flux as the FDA responds to new and evolving public health information and clinical evidence. For example, in December 2021, the FDA issued a draft guidance describing a potential transition plan for the regulation and distribution of emergency-use-authorized medical devices in the event that the current EUA declaration is terminated. Changes to FDA regulations or requirements could require changes to Ortho’s authorized tests, necessitate additional measures or make it impractical or impossible for Ortho to market its test. The termination of an EUA for Ortho’s products could adversely impact Ortho’s business, financial condition and results of operations.

Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire, retain or deploy key leadership and other personnel, or otherwise prevent new or modified products from being developed, cleared or approved or commercialized in a timely manner or at all, which could negatively impact Ortho’s business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, statutory, regulatory and policy changes, the FDA’s ability to hire and retain key personnel and accept the payment of user fees, and other events that may otherwise affect the FDA’s ability to perform routine functions. Average review times at the FDA have fluctuated in recent years as a result. In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable. Disruptions at the FDA and other agencies may also slow the time necessary for new medical devices and biologics or modifications to approved or cleared medical devices and biologics to be reviewed and/or cleared or approved by necessary government agencies, which would adversely affect Ortho’s business. For example, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical employees and stop critical activities.

Separately, in response to the COVID-19 pandemic, on March 10, 2020, the FDA announced its intention to postpone most inspections of foreign manufacturing facilities and products, and on March 18, 2020, the FDA temporarily postponed routine surveillance inspections of domestic manufacturing facilities. Subsequently, in July 2020, the FDA resumed certain on-site inspections of domestic manufacturing facilities subject to a risk-based prioritization system. The FDA utilized this risk-based assessment system to assist in determining when and where it was safest to conduct prioritized domestic inspections. In May 2021, the FDA outlined a detailed plan to move toward a more consistent state of inspectional operations, and in July 2021, the FDA resumed standard inspectional operations of domestic facilities and was continuing to maintain this level of operation as of September 2021. More recently, the FDA continues to monitor and implement changes to its inspections and related activities to ensure the safety of its employees and those of the firms it regulates as it adapts to the evolving COVID-19 pandemic. Regulatory authorities outside the United States may adopt similar restrictions or other policy measures in response to the COVID-19 pandemic. If a prolonged government shutdown occurs, or if global health concerns continue to prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews or other regulatory activities, it could significantly impact the ability of the FDA or other regulatory authorities to timely review and process Ortho’s regulatory submissions, which could have a material adverse effect on Ortho’s business.

59

Ortho may face business disruption and related risks resulting from President Biden’s invocation of the Defense Production Act, which could have a material adverse effect on Ortho’s business.

In response to the COVID-19 pandemic, President Biden invoked the Defense Production Act, codified at 50 U.S.C. § 4501 et seq. (the “Defense Production Act”). Pursuant to the Defense Production Act, the federal government may, among other things, require domestic industries to provide essential goods and services needed for the national defense. For example, in March 2021, President Biden invoked the Defense Production Act to expand production of the COVID-19 vaccine. While Ortho has not experienced any impact on its business as a result of such actions, Ortho continues to assess the potential impact that the invocation of the Defense Production Act may have on its ability to effectively conduct its business operations as planned, either as a result of becoming directly subject to the requirements of the Defense Production Act, Ortho’s suppliers becoming so subject and diverting deliveries of raw materials elsewhere, or otherwise. There can be no assurance that Ortho will not be impacted by any action taken by the federal government under the Defense Production Act, and any resulting disruption on Ortho’s ability to conduct business could have a material adverse effect on Ortho’s financial condition and results or operations.

Ortho could incur costs complying with environmental and health and safety requirements, or as a result of liability for contamination or other potential environmental harm or liability caused by Ortho’s operations.

Ortho’s operations and facilities are subject to various foreign, federal, state and local environmental, health and safety laws, rules, regulations and other requirements, including those governing the generation, use, manufacture, handling, transport, storage, treatment and disposal of, or exposure to, regulated materials, discharges and emissions to air and water, the cleanup of contamination and occupational health and safety matters. Noncompliance with these laws, rules, regulations and other requirements can result in fines or penalties or limitations on Ortho’s operations or liability for remediation costs, as well as claims alleging personal injury, property, natural resource or environmental damages. Ortho believes that its operations and facilities are operated in compliance in all material respects with existing environmental, health and safety requirements, including the operating permits required thereunder.

Ortho’s research and development and manufacturing processes involve the use of regulated materials subject to environmental, health and safety regulations. Ortho may incur liability as a result of any contamination or injury arising from a release of or exposure to such regulated materials. Under some environmental laws and regulations, Ortho could also be held responsible for costs relating to any contamination at its past or present facilities and at third-party disposal sites where Ortho has sent wastes for treatment or disposal. Liability for contamination at contaminated sites may be imposed without regard to whether Ortho knew of, or caused, the release or disposal of such regulated substances and, in some cases, liability may be joint or several. Any such future expenses or liability could have a negative impact on Ortho’s financial condition and results of operations. The enactment of stricter laws or regulations, the stricter interpretation of existing laws and regulations or the requirement to undertake the investigation or remediation of currently unknown environmental contamination at Ortho’s current or former facilities or at third-party sites where Ortho has sent waste for treatment or disposal may require Ortho to make additional expenditures or subject Ortho to additional liability or claims.

In addition, Ortho’s workers, properties and equipment may be exposed to potential operational hazards such as fires, process safety incidents, releases of regulated materials, malfunction of equipment, accidents and natural disasters, which could result in personal injury or loss of life, damage to or destruction of property and equipment or environmental damage, and could potentially result in a suspension of operations, harm to Ortho’s reputation and the imposition of civil or criminal fines or penalties, all of which could adversely affect Ortho’s business. See “Business of Ortho—Health, Safety and Environmental.”

Ortho is subject to healthcare regulations that could result in liability, require Ortho to change its business practices and restrict its operations in the future.

Ortho is subject to healthcare fraud and abuse regulation and enforcement by both the federal government and the governments of states and foreign countries in which Ortho conducts its business. In the United States, these healthcare laws and regulations include, for example:

| • |  | the federal Anti-Kickback Statute, which prohibits, among other things, persons or entities from soliciting, receiving, offering or providing remuneration, directly or indirectly, where one purpose is to induce either the referral of an individual for, or the purchase order or recommendation of, any item or services for which payment may be made under a federal healthcare program such as the Medicare and Medicaid programs. The U.S.

60

| government has interpreted this law broadly to apply to the marketing and sales activities of medical device manufacturers. In addition, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it to have committed a violation;

| • |  | the federal civil and criminal false claims laws, including the federal False Claims Act, which prohibits, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid or other federal healthcare programs that are false or fraudulent. Moreover, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act;

| • |  | the federal Civil Monetary Penalties Law, which prohibits, among other things, offering or transferring remuneration to a federal healthcare beneficiary that a person knows or should know is likely to influence the beneficiary’s decision to order or receive items or services reimbursable by the government from a particular provider or supplier;

| • |  | the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), which, in addition to privacy protections applicable to healthcare providers and other entities, prohibits, among other things, executing a scheme to defraud any healthcare benefit program and making false statements relating to healthcare matters. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it to have committed a violation;

| • |  | the federal Physician Payments Sunshine Act which requires certain applicable manufacturers of drugs, devices, biologics and medical supplies for which payment is available under certain federal healthcare programs, to monitor and report to the Centers for Medicare & Medicaid Services, or CMS, certain payments and other transfers of value to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), certain other healthcare providers, including physician assistants and nurse practitioners, and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members;

| • |  | the FDCA, which prohibits, among other things, the adulteration or misbranding of drugs, biologics and medical devices, and regulates device marketing;

| • |  | U.S. federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm customers; and

| • |  | state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws, which may apply to items or services reimbursed by any third-party payor, including commercial insurers; state laws requiring device companies to comply with specific compliance standards, restrict payments made to healthcare providers and other potential referral sources, and report information related to payments and other transfers of value to healthcare providers or marketing expenditures; and state laws related to insurance fraud in the case of claims involving private insurers.

These laws and regulations, among other things, constrain our business, marketing and other promotional and research activities by limiting the kinds of financial arrangements, including sales programs, we may have with hospitals, physicians or other potential purchasers of our products. In particular, these laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs, and other business arrangements, as well as interactions with healthcare professionals through consultant arrangements, product training, sponsorships, or other activities. Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare and other laws and regulations will involve substantial costs. Due to the breadth of these laws, the narrowness of statutory exceptions and regulatory safe harbors available, and the range of interpretations to which they are subject, governmental authorities may possibly conclude that our business practices may not comply with healthcare laws and regulations.

To enforce compliance with the healthcare regulatory laws, certain enforcement bodies have recently increased their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Responding to investigations can be time-and resource-consuming and can divert management’s attention from the business. We may be subject to private qui tam actions brought by individual whistleblowers on behalf of the federal or state governments, with potential liability under the federal False Claims Act including mandatory treble damages and significant per-claim penalties. Additionally, as a result of these investigations and qui tam actions, we may have to agree to additional compliance and reporting requirements as part of a

61

consent decree or corporate integrity agreement. Any such investigation or settlement could increase our costs or otherwise have an adverse effect on our business, financial condition and results of operations. Even an unsuccessful challenge or investigation into our practices could cause adverse publicity, and be costly to respond to.

If our operations are found to be in violation of any of the federal and state laws described above or any other current or future fraud and abuse or other healthcare laws and regulations that apply to us, we may be subject to significant penalties, including significant criminal, civil, and administrative penalties, damages, fines, exclusion from participation in government programs, such as Medicare and Medicaid, imprisonment, contractual damages, reputational harm, oversight if we become subject to a consent decree or corporate integrity agreement, disgorgement and we could be required to curtail, restructure or cease our operations. Any of the foregoing consequences will negatively affect our business, financial condition and results of operations.

Ortho’s failure to comply with the anti-corruption laws of the United States and various international jurisdictions could negatively impact Ortho’s reputation and results of operations.

Doing business on a worldwide basis requires Ortho to comply with the laws and regulations of the U.S. government and those of various international and sub-national jurisdictions, and Ortho’s failure to successfully comply with these rules and regulations may expose Ortho to liabilities. These laws and regulations apply to companies, individual directors, officers, employees and agents, and may restrict Ortho’s operations, trade practices, investment decisions and partnering activities. In particular, Ortho’s international operations are subject to U.S. and foreign anti-corruption laws and regulations, such as the FCPA, as well as anti-corruption laws of the various jurisdictions in which Ortho operates. The FCPA and other laws prohibit Ortho, and Ortho’s officers, directors, employees and agents acting on Ortho’s behalf, from corruptly offering, promising, authorizing or providing anything of value to foreign officials or entities for the purposes of influencing official decisions or obtaining or retaining business or otherwise obtaining favorable treatment. As part of Ortho’s business, Ortho deals with state-owned business enterprises, the employees and representatives of which may be considered foreign officials for purposes of the FCPA. Ortho is subject to the jurisdiction of various governments and regulatory agencies outside of the United States, which may bring Ortho’s personnel into contact with foreign officials responsible for issuing or renewing permits, licenses or approvals or for enforcing other governmental regulations. In addition, some of the international locations in which Ortho operates lack a developed legal system and have elevated levels of corruption. Ortho’s global operations expose Ortho to the risk of violating, or being accused of violating, the foregoing or other anti-corruption laws, including similar anti-corruption laws, rules and regulations of the various jurisdictions in which Ortho operates. Such violations could be punishable by criminal fines, imprisonment, civil penalties, disgorgement of profits, injunctions and debarment from government contracts, as well as other remedial measures. Investigations of alleged violations can be very expensive and disruptive. Additionally, Ortho faces a risk that its distributors, manufacturers and other third parties acting on Ortho’s behalf may potentially violate the FCPA or similar laws, rules or regulations of the various jurisdictions in which Ortho operates. Though these distributors, manufacturers and other third parties acting on Ortho’s behalf are not Ortho’s affiliated legal entities, such violations could expose Ortho to FCPA liability or liabilities under similar laws of the various jurisdictions in which Ortho operates and/or Ortho’s reputation may potentially be harmed by the distributors and manufacturers’ violations and resulting sanctions and fines.

Ortho’s international operations require it to comply with anti-terrorism laws and regulations and applicable trade embargoes.

Ortho is subject to trade and economic sanctions laws and other restrictions on international trade. The United States and other governments and their agencies impose sanctions and embargoes on certain countries, their governments and designated parties. In the United States, the economic and trade sanctions programs are principally administered and enforced by OFAC. Currently, OFAC maintains comprehensive trade and economic sanctions against the following countries and territories: Cuba, Iran, Syria, North Korea and the Crimea region of Ukraine. If Ortho fails to comply with these laws, Ortho could be subject to civil or criminal penalties, other remedial measures and legal expenses, which could adversely affect Ortho’s business, financial condition and results of operations.

Ortho cannot predict the nature, scope or effect of future regulatory requirements to which Ortho’s international sales and manufacturing operations might be subject or the manner in which existing laws might be administered or interpreted. Future regulations could limit the countries in which some of Ortho’s products may be manufactured or sold, or could restrict Ortho’s access to, or increase the cost of obtaining, products from foreign sources. The occurrence of any of the foregoing could have a material adverse effect on Ortho’s business, financial condition and results of operations.

Ortho’s collection, use and disclosure of personal information, including health information, is subject to federal and state privacy and security regulations, as well as data privacy and security laws outside the United States, including in the European Economic Area (the “EEA”) the United Kingdom and the People’s Republic of China, and Ortho’s failure to comply with those laws and regulations or to adequately secure the information Ortho holds could result in significant liability or reputational harm.

Ortho and its partners may be subject to federal, state, and foreign data protection laws and regulations. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing focus on privacy and data protection issues, which may affect its business and may increase its compliance costs and exposure to liability. In the United States, numerous federal and state laws and regulations, including state security breach notification laws, federal and state health information privacy laws (including HIPAA) and federal and state consumer protection laws, govern the collection, use, disclosure, and protection of personal information, including health-related information. Each of these laws is subject to varying interpretations by courts and government agencies, creating complex compliance issues. If Ortho fails to comply with applicable laws and regulations it could be subject to penalties or sanctions, including criminal penalties if Ortho knowingly obtains or discloses individually identifiable health information from a covered entity in a manner that is not authorized or permitted by HIPAA or applicable state laws.

In the United States, HIPAA imposes, among other things, certain standards relating to the privacy, security, transmission and breach reporting of individually identifiable health information. Certain states have also adopted comparable privacy and security laws and regulations, some of which may be more stringent than HIPAA. Such laws and regulations will be subject to interpretation by various courts and other governmental authorities, thus creating potentially complex compliance issues for Ortho and its future customers and strategic partners. For example, the California Consumer Privacy Act of 2018 (“CCPA”) went into effect on January 1, 2020. The CCPA creates individual privacy rights for California consumers and increases the privacy and security obligations of entities handling certain personal information. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation. Further, the California Privacy Rights Act (“CPRA”) recently passed in California. The CPRA will impose additional data protection obligations on covered businesses, including additional consumer rights processes, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses of sensitive data. It will also create a new California data protection agency authorized to issue substantive regulations and could result in increased privacy and information security enforcement. The majority of the provisions will go into effect on January 1, 2023, and additional compliance investment and potential business process changes may be required. Similar laws have passed in Virginia and Colorado, and have been proposed in other states and at the federal level, reflecting a trend toward more stringent privacy legislation in the United States. The enactment of such laws could have potentially conflicting requirements that would make compliance challenging. In the event that Ortho is subject to or affected by HIPAA, the CCPA, the CPRA or other domestic privacy and data protection laws, any liability from failure to comply with the requirements of these laws could adversely affect its financial condition.

Furthermore, the Federal Trade Commission (the “FTC”) and many state Attorneys General continue to enforce federal and state consumer protection laws against companies for online collection, use, dissemination and security practices that appear to be unfair or deceptive. For example, according to the FTC, failing to take appropriate steps to keep consumers’ personal information secure can constitute unfair acts or practices in or affecting commerce in violation of Section 5(a) of the Federal Trade Commission Act. The FTC expects a company’s data security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security and reduce vulnerabilities.

HIPAA as well as numerous other federal and state laws and regulations, govern the collection, dissemination, use, privacy, security, confidentiality, integrity and availability of personally identifiable information (“PII”), including protected health information (“PHI”). HIPAA applies national privacy and security standards for PHI to covered entities, including certain types of healthcare entities and their service providers that access PHI, known as business associates. HIPAA requires covered entities and business associates to maintain policies and procedures governing PHI that is used or disclosed, and to implement administrative, physical and technical safeguards to protect PHI, including PHI maintained, used and disclosed in electronic form. These safeguards include employee training, identifying business associates with whom covered entities need to enter into HIPAA-compliant contractual arrangements and various other measures. While Ortho undertakes substantial efforts to secure the PHI Ortho maintains, uses and discloses in electronic form, a cyber-attack or other intrusion that bypasses Ortho’s information security systems causing an information security breach, loss of PHI, PII or other data subject to privacy laws or a material disruption of Ortho’s operational systems could result in a material adverse impact on Ortho’s business, along with potentially substantial fines and penalties. Ongoing implementation and oversight of these security measures involves significant time, effort and expense.

63

HIPAA requires covered entities and their business associates to report breaches of unsecured PHI to affected individuals without unreasonable delay and in no case later than 60 days after the discovery of the breach by the covered entity or its agents.

Notification must also be made to the U.S. Department of Health and Human Services (“HHS”) and, in certain situations involving large breaches, to the media. HIPAA rules created a presumption that all non-permitted uses or disclosures of unsecured PHI are breaches unless the covered entity establishes that there is a low probability the information has been compromised. A data breach affecting sensitive personal information, including health information, also could result in significant legal and financial exposure and reputational damages that could potentially have an adverse effect on Ortho’s business.

HIPAA also authorizes state attorneys general to bring civil actions seeking either an injunction or damages in response to violations of HIPAA privacy and security regulations that threaten the privacy of state residents. While HIPAA does not create a private right of action allowing individuals to sue Ortho in civil court for violations of HIPAA’s requirements, its standards have been used as a basis for the duty of care in state civil suits, such as those for negligence or recklessness in the handling of PHI. In addition, HIPAA mandates that the Secretary of HHS conduct periodic compliance audits of covered entities and business associates.

In addition, many states in which Ortho operates may impose laws that are more protective of the privacy and security of PII than HIPAA. Where these state laws are more protective than HIPAA, Ortho may have to comply with their stricter provisions. Not only may some of these state laws impose fines and penalties upon violators, but some may afford private rights of action to individuals who believe their PII has been misused.

Both state and federal laws and regulations are subject to modification or enhancement of privacy and security protections at any time. Ortho’s business will continue to remain subject to any federal and state privacy-related laws and regulations that are more restrictive than the privacy regulations issued under HIPAA. Sweeping privacy measures in certain states such as the California Consumer Privacy Act impose European-like standards for the protection of personal data and allow for a private right of action. These statutes vary and could impose additional requirements on Ortho and more severe penalties for disclosures of confidential health information. New health and consumer information standards could have a significant effect on the manner in which Ortho does business, and the cost of complying with new standards could be significant. Ortho may not remain in compliance with the diverse privacy and security requirements in all of the jurisdictions in which Ortho does business. If Ortho fails to comply with such state laws, it could incur substantial civil monetary or criminal penalties.

Ortho is also subject to data privacy and security laws in jurisdictions outside of the United States. For example, in the EEA and the United Kingdom, Ortho is subject to the General Data Protection Regulation 2016/679 (the “GDPR”) and the United Kingdom data protection regime consisting primarily of the UK General Data Protection Regulation and the UK Data Protection Act 2018 (collectively, the “UK GDPR”), which could limit Ortho’s ability to collect, control, process, share, disclose and otherwise use personal data (including health and medical information which are subject to strict requirements). Maintaining compliance with the GDPR and UK GDPR could cause Ortho’s compliance costs to increase, ultimately having an adverse impact on Ortho’s business. Ortho is implementing measures to comply with these laws as part of Ortho’s comprehensive compliance program with input from external advisors to address Ortho’s compliance with these obligations under GDPR. Failure to comply with the GDPR and UK GDPR may result in fines up to the greater of €20 million / £17.5 million or 4% of total annual revenue. In addition to the foregoing, a breach of the GDPR and UK GDPR could result in regulatory investigations, reputational damage, orders to cease or change Ortho’s processing of its data, enforcement notices or assessment notices (for a compulsory audit). Ortho may also face civil claims including representative actions and other class action type litigation (where individuals have suffered harm), potentially amounting to significant compensation or damages liabilities, as well as associated costs, diversion of internal resources and reputational harm. In addition, in September 2021, the UK government launched a consultation on its proposals for wide-ranging reform of UK data protection laws following Brexit. There is a risk that any material changes which are made to the UK data protection regime could result in the European Commission reviewing the UK adequacy decision (enabling data transfers from EU member states to the UK without additional safeguards) and the UK losing its adequacy decision if the European Commission deems the UK to no longer provide adequate protection for personal data. The relationship between the United Kingdom and the European Union in relation to certain aspects of data protection law remains unclear, and it is unclear how UK data protection laws and regulations will develop in the medium to long term, and how data transfers to and from the United Kingdom will be regulated in the long term. These changes could lead to additional costs and increase Ortho’s overall risk exposure.

Ortho is also subject to European Union and United Kingdom rules with respect to cross-border transfers of personal data out of the EEA and the United Kingdom, respectively. Recent legal developments in Europe have created complexity and

64

uncertainty regarding transfers of personal data from the EEA to the United States. For instance, on July 16, 2020, the Court of Justice of the European Union (the “CJEU”) invalidated the EU-U.S. Privacy Shield Framework (the “Privacy Shield”) under which personal data could be transferred from the EEA to U.S. entities who had self-certified under the Privacy Shield scheme. While the CJEU did not invalidate standard contractual clauses (a standard form of contract approved by the European Commission as an adequate personal data transfer mechanism, and potential alternative to the Privacy Shield), it made clear that reliance on them alone may not necessarily be sufficient in all circumstances. Ortho currently relies on the standard contractual clauses among other data transfer mechanisms allowed pursuant to the GDPR to transfer personal data outside the EEA or the United Kingdom, including to the United States. The European Commission has published revised standard contractual clauses for data transfers from the EEA: the revised clauses must be used for relevant new data transfers from September 27, 2021; existing standard contractual clauses arrangements must be migrated to the revised clauses by December 27, 2022. Ortho will be required to implement the revised standard contractual clauses, in relation to both relevant existing contracts and transfer arrangements and additional or new contracts and arrangements, within the relevant time frames. The revised standard contractual clauses apply only to the transfer of personal data outside of the EEA and not the United Kingdom; the UK’s Information Commissioner’s Office launched a public consultation on its draft revised data transfers mechanisms in August 2021. Ortho is monitoring the outcome of this, and we may be required to implement new or revised documentation and processes in relation to data transfers subject to the UK GDPR within the relevant time frames. As supervisory authorities issue further guidance on personal data export mechanisms, including circumstances where the standard contractual clauses cannot be used, and/or start taking enforcement action, Ortho could suffer additional costs, complaints, regulatory investigations or fines, and if Ortho is otherwise unable to transfer personal data between and among countries and regions in which Ortho operates, it could affect the manner in which Ortho provides its services and the geographical location or segregation of Ortho’s relevant systems and operations, which could adversely affect Ortho’s financial results.

Ortho depends on a number of third-parties in relation to the operation of its business, a number of which process personal data on Ortho’s behalf. With each such third party, Ortho attempts to mitigate the associated risks of using third parties by performing applicable security assessments and detailed due diligence, entering into contractual arrangements to require that providers only process personal data according to Ortho’s instructions, and that they have sufficient technical and organizational security measures in place. Where Ortho transfers personal data outside the EEA or the United Kingdom to such third parties, Ortho does so in compliance with the relevant data export requirements, as described above. There is no assurance that these contractual measures and Ortho’s own privacy and security-related safeguards will fully protect Ortho from the risks associated with the third-party processing. Any violation of data or security laws by Ortho’s third-party processors could have a material adverse effect on Ortho’s business and result in the fines and penalties outlined below.

Ortho is also subject to evolving privacy laws on cookies and e-marketing. In the European Union, regulators are increasingly focusing on compliance with requirements in the online behavioral advertising ecosystem, and current national laws that implement the ePrivacy Directive will be replaced by an EU regulation known as the ePrivacy Regulation which will significantly increase fines for non-compliance. While the text of the ePrivacy Regulation is still under development, a recent European court decision and regulators’ recent guidance are driving increased attention to cookies and tracking technologies. In the United States, the Federal Trade Commission and many state laws have increasingly focused on the collection and use of behavioral data including geolocation and biometric information. As regulators start to enforce a strict approach (which has already started in Germany), this could lead to substantial costs, require significant systems changes, limit the effectiveness of Ortho’s marketing activities, divert the attention of Ortho’s technology personnel, adversely affect Ortho’s margins, increase costs and subject Ortho to additional liabilities.

Recently many countries have enacted legislation to strengthen privacy laws to protect their residents’ personal data. Some countries’ laws have been modeled on GDPR, including fines and penalties such as Brazil’s enacted data protection law and similar pending legislation in Chile. Ortho is currently monitoring the evolving data protection landscape so that Ortho can comply with the requirements in the countries in which Ortho does business.

Data compliance in other countries outside EEA, the United Kingdom and the United States may be even more complex and varied making it difficult to comply with them all. China’s legislation and regulation of the healthcare industry involves multiple pieces of legislation prescribing complex regulatory requirements governing different types of data across a continuum of care, and various supervisory authorities frequently conduct inspections and investigations. For example, under China’s Cybersecurity Law, any collection, use, transfer and storage of personal information of a Chinese citizen through a network by the network operator should be based on the three principles of legitimacy, justification and necessity and requires the consent of the data subject. The rules, purposes, methods and ranges of such collection should also be disclosed

65

to the data subject. China’s data localization requirements are becoming increasingly common in sector-specific regulations. China’s Cybersecurity Law requires operators of critical information infrastructure (“CIIOs”) to store personal information and important data collected and generated from the critical information infrastructure within China. Failure to do so can result in fines of up to RMB 100,000 for the relevant entity as well as for the personnel directly responsible.

China’s Data Security Law (“Data Security Law”) became effective on September 1, 2021. The primary purpose of the Data Security Law is to regulate data activities, safeguard data security, promote data development and usage, protect individuals and entities’ legitimate rights and interests, and safeguard state sovereignty, state security and development interests. The Data Security Law applies extraterritorially, and to a broad range of activities that involve “data” (not only personal or sensitive data). Under the Data Security Law, entities and individuals carrying out data activities must abide by various data security obligations. For example, the Data Security Law proposes to classify and protect data based on the importance of data to the state’s economic development, as well as the degree of harm it will cause to national security, public interests, or legitimate rights and interests of individuals or organizations when such data is tampered with, destroyed, leaked, or illegally acquired or used. The appropriate level of protective measures is required to be taken for each respective class of data. The Data Security Law also echoes the data localization requirement in the Cybersecurity Law and requires important data to be stored locally in China. Such important data may only be transferred outside of China subject to compliance with certain data transfer restrictions, such as passing a security assessment organized by the relevant authorities.

Notably, China’s Personal Information Protection Law (“PIPL”), similar to the GDPR, applies extraterritorially. The PIPL is intended to clarify the scope of application, the definitions of personal information and sensitive personal information (which includes medical and health information), the legality of personal information processing and the basic requirements of notice and consent, among other things. The PIPL also sets out data localization requirements for CIIOs and personal information processors who process personal information above a certain threshold prescribed by the relevant authorities. The PIPL also includes a list of rules which must be complied with prior to the transfer of personal information outside of China, such as compliance with a security assessment or certification by an agency designated by the relevant authorities or entering into standard form model contracts approved by the relevant authorities with the overseas recipient. Failure to comply with PIPL can result in fines of up to RMB 50 million or 5% of the prior year’s total annual revenue for the personal information processor and/or a suspension of services or data processing activities. Other potential penalties include a fine of up to RMB 1 million on the person in charge or directly responsible personnel and, in serious cases, individuals and entities may be exposed to criminal liabilities under other local Chinese law, such as the Criminal Law of the People’s Republic of China. The PIPL also prohibits responsible personnel for violations of the PIPL from holding high-level management or data protection officer positions in relevant enterprises.

In addition to China’s Cybersecurity Law, the Data Security Law and the PIPL, the relevant government authorities of People’s Republic of China promulgated several regulations or released a number of draft regulations for public comments which are designed to provide further implemental guidance in accordance with the laws mentioned above.

Ortho cannot predict what impact the new laws and regulations, in particular the Data Security Law or PIPL, or the increased costs of compliance, if any, will have on Ortho’s operations in China due to their recent enactment and the limited guidance available, particularly on PIPL, which entities are awaiting further guidance on. It is also generally unclear how the laws will be interpreted and enforced in practice by the relevant government authorities as often the abovementioned laws are drafted broadly and leaves great discretion to the relevant government authorities to exercise.

Compliance with China’s data laws mentioned above, the GDPR and UK GDPR and the various other global data privacy laws that Ortho is subject to has required, and may continue to require, significant company resources and expenditures, and may require further changes in Ortho’s products, services or business model that increase competition or reduce revenue.

Although Ortho works to comply with applicable laws, regulations and standards, its contractual obligations and other legal obligations, these requirements are evolving and may be modified, interpreted and applied in an inconsistent manner from one jurisdiction to another, and may conflict with one another or other legal obligations with which Ortho must comply. Any failure or perceived failure by Ortho or its employees, representatives, contractors, consultants, collaborators, or other third parties to comply with such requirements or adequately address privacy and security concerns, even if unfounded, could result in additional cost and liability to Ortho, damage its reputation, and adversely affect its business and results of operations.

Risks Relating to Ortho’s Information Technology and Intellectual Property

Ortho’s data management and information technology systems are critical to maintaining and growing Ortho’s business.

Ortho’s business is dependent on the effective use of information technology and, consequently, technology failure or obsolescence may negatively impact Ortho’s business. In addition, data acquisition, data quality control, data privacy, data security and data analysis are intense and complex processes subject to error. Untimely, incomplete or inaccurate data, flawed analysis of data or Ortho’s inability to properly integrate, implement, protect and update systems could have a material adverse impact on Ortho’s business and results of operations. Ortho expects that it will need to continue to improve and further integrate its information technology systems on an ongoing basis in order to effectively run Ortho’s business. If Ortho fails to successfully manage its information technology systems, its business and operating results could be adversely affected.

Ortho’s ability to protect its information systems and electronic transmissions of personal data and sensitive data from data corruption, cyber-based attacks, security breaches or privacy violations is critical to the success of Ortho’s business.

Ortho is highly dependent on information technology networks and systems, including its office networks, operational environment, special purpose networks, systems and software used to operate Ortho’s instruments and devices and those networks and systems managed by vendors or third parties, to securely process, transmit and store electronic information (including sensitive data such as trade secrets, confidential business information and personal data relating to employees, customers and business partners). Like any large corporation, from time to time the information systems on which Ortho relies, including those controlled and managed by third-parties, may be subject to computer viruses, malicious software, attacks by hackers and other forms of cyber intrusions or unauthorized access, any of which can create system disruptions, shutdowns or unauthorized disclosure of sensitive data. In addition, a security breach that leads to disclosure of information protected by privacy laws could compel Ortho to comply with breach notification requirements under applicable laws, potentially resulting in litigation or regulatory action, or otherwise subjecting Ortho to liability under laws that protect personal data.

If Ortho experiences a significant technology incident, such as a serious product vulnerability, security breach or a failure of a system that is critical for the operations of Ortho’s business, it could impair Ortho’s ability to operate its business, including its ability to provide maintenance and support services to Ortho’s customers. If this happens, Ortho’s revenues could decline and its business could suffer, and it may need to make significant further investments to protect data and infrastructure. An actual or perceived vulnerability, failure, disruption or breach of Ortho’s network or privileged account security in Ortho’s systems also could adversely affect the market perception of Ortho’s products and services, as well as Ortho’s perception among new and existing customers. Additionally, a significant security breach could subject Ortho to potential liability, litigation and regulatory or other government action. If any of the foregoing were to occur, Ortho’s business may suffer.

Ortho attempts to mitigate the above risks by employing a number of measures, including monitoring and testing of Ortho’s security controls, employee training and maintenance of protective systems and contingency plans. Further, Ortho’s contractual arrangements with service providers aim to ensure that third-party cybersecurity risks are appropriately mitigated. Ortho also maintains insurance relating to cybersecurity incidents, which Ortho cannot guarantee will be adequate. It is impossible to eliminate all cybersecurity risk and thus Ortho’s systems, products and services, as well as those of its service providers, remain potentially vulnerable to known or unknown threats. Additionally, Ortho’s information technology systems may also be vulnerable to damage or interruption from circumstances beyond Ortho’s control, including fire, natural disasters, power outages and system failures. Any system outages or security breaches, whether caused intentionally or unintentionally, can interrupt Ortho’s operations, delay production and shipments, result in theft of trade secrets and intellectual property, damage Ortho’s reputation, result in defective products or services, give rise to legal proceedings, liabilities and penalties, and cause Ortho to incur increased costs for insurance premiums, security, remediation, and regulatory compliance.

Information security risks have generally increased in recent years because of the increased proliferation, sophistication and availability of complex malware and hacking tools to carry out cyber-attacks. As a result of the COVID-19 pandemic, Ortho may also face increased cybersecurity risks due to its reliance on internet technology and the number of its employees who are working remotely, which may create additional opportunities for cybercriminals to exploit vulnerabilities. Furthermore, because the techniques used to obtain unauthorized access to, or to sabotage, systems change frequently and often are not recognized until launched against a target, Ortho may be unable to anticipate these techniques or implement adequate preventative measures. Ortho may also experience security breaches that may remain undetected for an extended period of

67

time. As cyber threats continue to evolve, Ortho may be required to expend additional resources to mitigate new and emerging threats while continuing to enhance Ortho’s information security capabilities or to investigate and remediate security vulnerabilities.

Ortho’s inability to protect and enforce its intellectual property rights could adversely affect its financial results.

Intellectual property rights both in the United States and in foreign countries, including patents, trade secrets, proprietary information, trademarks and trade names, are important to Ortho’s business and will be critical to its ability to grow and succeed in the future. Ortho makes strategic decisions on whether to apply for intellectual property protection and what kind of protection to pursue based on a cost-benefit analysis. While Ortho endeavors to protect its intellectual property rights in certain jurisdictions in which its products are produced or used and in jurisdictions into which Ortho’s products are imported, the decision to file for intellectual property protection is made on a case-by-case basis. Because of the differences in foreign trademark, patent and other laws concerning proprietary rights, Ortho’s intellectual property rights may not receive the same degree of protection in foreign countries as they would in the United States. Additionally, certain of Ortho’s intellectual property rights are held through its license agreements and collaboration arrangements with third parties. Because of the nature of these licenses and arrangements, Ortho cannot assure you that it would be able to retain all of these intellectual property rights upon termination of such licenses and collaboration arrangements. Ortho’s failure to obtain or maintain adequate protection of its intellectual property rights for any reason could have a material adverse effect on its business, results of operations and financial condition.

Ortho has applied for patent protection relating to certain existing and proposed products, processes and services in certain jurisdictions. While Ortho generally considers applying for patents in those countries where it intends to make, has made, uses or sells patented products, Ortho may not accurately assess all of the countries where patent protection will ultimately be desirable. If Ortho fails to timely file a patent application in any such country, Ortho may be precluded from doing so at a later date. Furthermore, Ortho cannot assure you that its pending patent applications will not be challenged by third parties or that such applications will eventually be issued by the applicable patent offices as patents. Ortho also cannot assure you that the patents issued as a result of its foreign patent applications will have the same scope of coverage as its U.S. patents. It is possible that only a limited number of the pending patent applications will result in issued patents, which may have a materially adverse effect on Ortho’s business and results of operations.

The patents Ortho owns could be challenged, invalidated or circumvented by others and may not be of sufficient scope or strength to provide Ortho with any meaningful protection or commercial advantage. Furthermore, Ortho’s existing patents are subject to challenges from third parties which may result in invalidations and will all eventually expire, after which Ortho will not be able to prevent Ortho’s competitors from using Ortho’s previously patented technologies, which could materially adversely affect Ortho’s competitive advantage stemming from those products and technologies. Ortho also cannot assure you that competitors will not infringe Ortho’s patents, or that Ortho will have adequate resources to enforce Ortho’s patents.

Ortho also licenses third parties to use Ortho’s patents and know-how. In an effort to preserve Ortho’s intellectual property rights, Ortho enters into license agreements with these third parties, which govern the use of Ortho’s patents, know-how and other confidential, proprietary information. Although Ortho makes efforts to police the use of its intellectual property by its licensees, Ortho cannot assure you that these efforts will be sufficient to ensure that Ortho’s licensees abide by the terms of their licenses. In the event that Ortho’s licensees fail to do so, Ortho’s intellectual rights could be impaired.

Ortho also relies on unpatented proprietary technology. It is possible that others will independently develop the same or similar technology or otherwise obtain access to Ortho’s unpatented technology. To protect Ortho’s trade secrets and other proprietary information, Ortho requires certain employees, consultants, advisors and collaborators to enter into confidentiality agreements as Ortho deems appropriate. Ortho cannot assure you that it will be able to enter into these confidentiality agreements or that these agreements will provide meaningful protection for Ortho’s trade secrets, know-how or other proprietary information in the event of any unauthorized use, misappropriation or disclosure of such trade secrets, know-how or other proprietary information. If Ortho is unable to maintain the proprietary nature of Ortho’s technologies, it could be materially adversely affected.

Ortho relies on its trademarks, trade names and brand names to distinguish its products from the products of its competitors, and have registered or applied to register many of these trademarks. Ortho cannot assure you that its trademark applications will be approved. Third parties may also oppose Ortho’s trademark applications, or otherwise challenge Ortho’s use of the trademarks. In the event that Ortho’s trademarks are successfully challenged, Ortho could be forced to rebrand its products,

68

which could result in loss of brand recognition, and could require Ortho to devote resources to advertising and marketing new brands. Further, Ortho cannot assure you that competitors will not infringe Ortho’s trademarks, or that Ortho will have adequate resources to enforce Ortho’s trademarks.

Risks Relating to Ortho’s Taxation

Legislative or taxation changes or HM Revenue & Customs (“HMRC”) enforcement actions may have a material adverse impact on Ortho’s business, results of operations and financial condition.

Ortho is subject to the laws of England and Wales and the taxation rules administered by HMRC. Changes in legislation or regulations and actions by regulators, including changes in administration and enforcement policies, could from time to time require operational improvements or modifications, including in relation to the conduct of reviews and audits, that could result in higher costs or restrict Ortho’s ability to operate its business and, as a result, have a material adverse effect on its business, results of operations and financial condition. HMRC may also take enforcement actions against Ortho which may result in fines, penalties and/or interest charges being imposed on Ortho which may have a material adverse effect on its business, results of operations and financial condition.

Changes in tax laws or exposures to additional tax liabilities could negatively impact Ortho’s operating results.

Changes in tax laws or regulations around the world, including in the United States and as led by the Organization for Economic Cooperation and Development, could negatively impact Ortho’s effective tax rate and results of operations. A change in statutory tax rate or certain international tax provisions in any country would result in the revaluation of Ortho’s deferred tax assets and liabilities related to that particular jurisdiction in the period in which the new tax law is enacted. This change would result in an expense or benefit recorded to Ortho’s consolidated statement of operations. Ortho closely monitors these proposals as they arise in the countries where Ortho operates. Changes to tax laws or regulations may occur at any time, and any related expense or benefit recorded may be material to the fiscal quarter and year in which the law change is enacted.

Ortho’s ability to use its net operating loss carry forwards to offset future taxable income are expected to be subject to certain limitations and Ortho could be subject to tax audits or examinations that could result in a loss of Ortho’s net operating losses and/or cash tax exposures.

As of January 2, 2022, Ortho had NOLs of approximately $889 million in the United States and approximately $467 million in Luxembourg due to prior period losses. In addition, Ortho had approximately $446 million of U.S. carryforward interest expense and approximately $214 million of Luxembourg carryforward interest expense as of January 2, 2022. Certain of these carryforwards, if not utilized, will begin to expire through 2037. Realization of these carryforwards depends on future income, and there is a risk that Ortho’s existing carryforwards could expire unused and be unavailable to offset future income tax liabilities, which could adversely affect Ortho’s cash flows.

In general, under Section 382 of the Code, a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its tax attributes, including its NOLs to offset future taxable income. As of January 2, 2022, the Ortho Scheme is expected to result in an ownership change under Section 382 of the Code. There is risk that subsequent changes in ownership could result in another Section 382 ownership change and further limit the use of Ortho’s tax attributes. Ortho’s NOLs may also be impaired under state laws. There is also a risk that due to regulatory changes, or other unforeseen reasons, Ortho’s existing NOLs could expire or otherwise be unavailable to offset future income tax liabilities. Furthermore, any available NOLs would have value only to the extent there is income in the future against which such NOLs may be offset. For these reasons, Ortho may not be able to realize a tax benefit from the use of Ortho’s NOLs, whether or not Ortho attains profitability.

Risks Relating to Ortho’s Indebtedness

Ortho’s substantial indebtedness could adversely affect Ortho’s financial condition, limit Ortho’s ability to raise additional capital to fund its operations and prevent Ortho from fulfilling its obligations under its indebtedness.

Ortho has a significant amount of indebtedness. As a result of Ortho’s substantial indebtedness, a significant amount of Ortho’s cash flows are required to pay interest and principal on Ortho’s outstanding indebtedness, and Ortho may not

69

generate sufficient cash flows from operations, or have future borrowings available under the Revolving Credit Facility, to enable Ortho to repay its indebtedness or to fund its other liquidity needs. As of January 2, 2022, Ortho had total indebtedness of $2,276.9 and availability under its Revolving Credit Facility of $453.7 million (net of $46.3 million of outstanding letters of credit).

Subject to the limits contained in the Credit Agreement, the indenture governing the $405.0 million in aggregate principal amount of 7.250% Senior Notes due 2028 issued by Ortho-Clinical Diagnostics S.A., a société anonyme organized under the laws of the Grand Duchy of Luxembourg (the “Lux Co-Issuer”) and Ortho-Clinical Diagnostics, Inc., a New York corporation (the “U.S. Co-Issuer”) (the “2028 Notes” and such indenture, the “2028 Notes Indenture”), the indenture governing the $240.0 million in aggregate principal amount of 7.375% Senior Notes due 2025 issued by the Lux Co-Issuer and the U.S. Co-Issuer (the “2025 Notes” and such indenture, the “2025 Notes Indenture”), the three-year accounts receivable program (the “Financing Program”) and Ortho’s other debt instruments, Ortho may incur substantial additional debt from time to time to finance working capital, capital expenditures, investments or acquisitions, or for other purposes. If Ortho does so, the risks related to Ortho’s high level of debt would increase. Specifically, Ortho’s high level of debt could have important consequences to you, including:

| • |  | making it more difficult for Ortho to satisfy its obligations with respect to Ortho’s debt, and if Ortho fails to comply with these obligations, an event of default could result;

| • |  | limiting Ortho’s ability to obtain additional financing to fund future working capital, capital expenditures, investments or acquisitions or other general corporate requirements;

| • |  | requiring a substantial portion of Ortho’s cash flows to be dedicated to debt service payments instead of other purposes, thereby reducing the amount of cash flows available for working capital, capital expenditures, investments or acquisitions and other general corporate purposes;

| • |  | increasing Ortho’s vulnerability to general adverse economic and industry conditions;

| • |  | exposing Ortho to the risk of increased interest rates as certain of Ortho’s borrowings, including borrowings under the Senior Secured Credit Facilities, are at variable rates of interest;

| • |  | limiting Ortho’s flexibility in planning for and reacting to changes in the industry in which Ortho competes as well as changing business and economic conditions;

| • |  | restricting Ortho from making strategic acquisitions or causing Ortho to make non-strategic divestitures;

| • |  | impairing Ortho’s ability to obtain additional financing in the future;

| • |  | preventing Ortho from raising the funds necessary to repurchase all of the 2025 Notes and the 2028 Notes (collectively, the “Senior Notes”) tendered to Ortho upon the occurrence of certain changes of control, which failure to repurchase would constitute an event of default under the 2025 Notes Indenture or the 2028 Notes Indenture;

| • |  | placing Ortho at a disadvantage compared to other, less leveraged competitors and affecting Ortho’s ability to compete; and

| • |  | increasing Ortho’s cost of borrowing.

The occurrence of any one of these events could have a material adverse effect on Ortho’s business, financial condition, results of operations and ability to satisfy Ortho’s obligations in respect of Ortho’s outstanding debt.

Furthermore, borrowings under Ortho’s Senior Secured Credit Facilities are at variable rates of interest and expose Ortho to interest rate risk. Recent interest rates have been at historically low levels. If interest rates increase, Ortho’s debt service obligations on the variable rate indebtedness will increase even though the amount borrowed may remain the same, and Ortho’s net income and cash flows, including cash available for servicing Ortho’s indebtedness, will correspondingly decrease. As of January 2, 2022, $1,292.8 million in aggregate principal amount of indebtedness under Ortho’s Term Loan Facilities is subject to variable interest rates subject to the London interbank offered rate (“LIBOR”). Assuming no prepayments of Ortho’s Term Loan Facilities and that Ortho’s Revolving Credit Facility is fully drawn (and to the extent that the LIBOR is in excess of the 0.00% floor rate applicable to Ortho’s Senior Secured Credit Facilities), each one-eighth percent change in interest rates, prior to the impact of derivative instruments, would result in a $2.6 million change in annual interest expense on the indebtedness under Ortho’s Senior Secured Credit Facilities. In addition, certain of Ortho’s variable

70

rate indebtedness uses LIBOR as a benchmark for establishing the rate. LIBOR is the subject of recent national, international and other regulatory guidance and proposals for reform. These reforms and other pressures will cause LIBOR to disappear entirely or be deemed unrepresentative after June 30, 2023 to perform differently than in the past. The consequences of these developments cannot be entirely predicted, but could include an increase in the cost of Ortho’s variable rate indebtedness. Ortho has entered into a series of interest rate cap and interest rate swap agreements to hedge Ortho’s interest rate exposures related to Ortho’s variable rate borrowings under the Senior Secured Credit Facilities. However, it is possible that these interest rate cap and interest rate swap agreements or any future interest rate cap agreements or swaps Ortho enters into may not fully or effectively mitigate Ortho’s interest rate risk and Ortho may decide not to maintain interest rate swaps in the future.

In addition, amounts drawn under Ortho’s Senior Secured Credit Facilities may bear interest rates in relation to LIBOR, depending on Ortho’s selection of repayment options. On March 5, 2021, the ICE Benchmark Administration, the administrator of LIBOR, and the Financial Conduct Authority, the regulatory supervisor of the ICE Benchmark Administration, announced that the final publication or representativeness date for LIBOR for: (i) Sterling and Euros will be December 31, 2021, (ii) Dollars for 1-week and 2-month tenor settings will be December 31, 2021 and (iii) Dollars for overnight, 1-month, 3-month, 6-month and 12-month tenor settings will be June 30, 2023. In the United States, the Alternative Rates Reference Committee, a group of market participants convened in 2014 to help ensure a successful transition away from USD LIBOR, has identified the Secured Overnight Financing Rate (“SOFR”) as its preferred alternative rate. SOFR is a measure of the cost of borrowing cash overnight, collateralized by U.S. Treasury securities, and is based on directly observable U.S. Treasury-backed repurchase transactions. On December 24, 2021, Ortho entered into an amendment to the Senior Secured Credit Facilities to account for the cessation of LIBOR for Sterling, Euros and Japanese Yen and the alternative replacement rates with respect to such currencies, as applicable. As all tenor settings for LIBOR will cease to exist on June 30, 2023, Ortho will need to renegotiate certain provisions of its Senior Secured Credit Facilities and may not be able to do so with terms that are favorable to Ortho. The overall financing market may be disrupted as a result of the phase-out or replacement of LIBOR. Disruption in the financial market or the inability to renegotiate Ortho’s Senior Secured Credit Facilities with favorable terms could have a material adverse effect on Ortho’s business, financial position, operating results and cash flows.

Ortho may not be able to generate sufficient cash flows from operating activities to service all of its indebtedness, and may be forced to take other actions to satisfy its obligations under its indebtedness, which may not be successful.

Ortho’s inability to generate sufficient cash flows to satisfy its debt obligations, or to refinance Ortho’s indebtedness on commercially reasonable terms or at all, would materially and adversely affect Ortho’s business, financial position and results of operations and Ortho’s ability to satisfy its debt obligations.

Additionally, if Ortho cannot make scheduled payments on its debt, Ortho will be in default, and holders of the Senior Notes could declare all outstanding principal and interest to be due and payable, the lenders under the Senior Secured Credit Facilities could terminate their commitments to loan additional money to Ortho, the lenders could foreclose against the assets securing their borrowings and Ortho could be forced into bankruptcy or liquidation. All of these events could result in your losing all or a part of your investment.

Ortho’s ability to make scheduled payments on or refinance its debt obligations depends on Ortho’s financial condition and operating performance, which are subject to prevailing economic and competitive conditions and to financial, business, legislative, regulatory and other factors beyond Ortho’s control. Ortho might not be able to maintain a level of cash flows from operating activities sufficient to permit Ortho to pay the principal, premium, if any, and interest on its indebtedness.

If Ortho’s cash flows and capital resources are insufficient to fund its debt service obligations, Ortho could face substantial liquidity problems and could be forced to reduce or delay investments and capital expenditures or to dispose of material assets or operations, seek additional debt or equity capital or restructure or refinance its indebtedness. In addition, Ortho’s cash flows may be negatively impacted if Ortho is required to pay back borrowing under the Financing Program sooner than anticipated if there is a reduction in the borrowing base. Ortho may not be able to effect any such alternative measures on commercially reasonable terms or at all and, even if successful, those alternative actions may not allow Ortho to meet its scheduled debt service obligations. The Credit Agreement, the 2025 Notes Indenture and the 2028 Notes Indenture restrict Ortho’s ability to dispose of assets and use the proceeds from such dispositions and may also restrict Ortho’s ability to raise debt or equity capital to be used to repay other indebtedness when it becomes due. Because of these restrictions, Ortho may not be able to consummate those dispositions or to obtain proceeds in an amount sufficient to meet any debt service obligations then due.

71

In addition, Ortho conducts substantially all of its operations through its subsidiaries, some of which are not guarantors of Ortho’s indebtedness. Accordingly, repayment of Ortho’s indebtedness is dependent on the generation of cash flows by Ortho’s subsidiaries and their ability to make such cash available to Ortho, by dividend, debt repayment or otherwise. Unless they are guarantors of Ortho’s indebtedness, Ortho’s subsidiaries do not have any obligation to pay amounts due on Ortho’s indebtedness or to make funds available for that purpose. Ortho’s subsidiaries may not be able to, or may not be permitted to, make distributions to enable Ortho to make payments in respect of its indebtedness. Each subsidiary is a distinct legal entity, and, under certain circumstances, legal and contractual restrictions may limit Ortho’s ability to obtain cash from its subsidiaries. While the Credit Agreement, the 2025 Notes Indenture and the 2028 Notes Indenture limit the ability of Ortho’s subsidiaries to incur consensual restrictions on their ability to pay dividends or make other intercompany payments to Ortho, these limitations are subject to qualifications and exceptions. In the event that Ortho does not receive distributions from Ortho’s subsidiaries, Ortho may be unable to make required principal and interest payments on its indebtedness.

The terms of the Credit Agreement, the 2025 Notes Indenture and the 2028 Notes Indenture impose restrictions that may limit Ortho’s current and future operating flexibility, particularly Ortho’s ability to respond to changes in the economy or Ortho’s industry or to take certain actions, which could harm Ortho’s long-term interests and may limit Ortho’s ability to make payments on its indebtedness.

The Credit Agreement, the 2025 Notes Indenture and the 2028 Notes Indenture contain a number of restrictive covenants that impose significant operating and financial restrictions on Ortho and may limit Ortho’s ability to engage in acts that may be in Ortho’s long-term best interest, including restrictions on Ortho’s ability, and the ability of Ortho’s subsidiaries, to:

| • |  | incur additional indebtedness and guarantee indebtedness;

| • |  | pay dividends or make other distributions in respect of, or repurchase or redeem, capital stock;

| • |  | prepay, redeem or repurchase certain indebtedness;

| • |  | make loans and investments;

| • |  | sell, transfer or otherwise dispose of assets;

| • |  | incur liens;

| • |  | enter into transactions with affiliates;

| • |  | enter into new lines of business or alter the businesses Ortho conducts;

| • |  | designate any of Ortho’s subsidiaries as unrestricted subsidiaries;

| • |  | enter into agreements restricting Ortho’s subsidiaries’ ability to pay dividends; and

| • |  | consolidate, merge, transfer or sell all or substantially all of Ortho’s assets or the assets of Ortho’s subsidiaries.

As a result of all of these restrictions, Ortho may be:

| • |  | limited in how Ortho conducts its business;

| • |  | unable to raise additional debt or equity financing to operate during general economic or business downturns; or

| • |  | unable to compete effectively or to take advantage of new business opportunities.

These restrictions might hinder Ortho’s ability to grow in accordance with its strategy.

While Ortho believes that they have not historically had this impact, these covenants could materially and adversely affect Ortho’s ability to finance its future operations or capital needs. Furthermore, they may restrict Ortho’s ability to expand, pursue Ortho’s business strategies and otherwise conduct Ortho’s business. Ortho’s ability to comply with these covenants may be affected by circumstances and events beyond Ortho’s control, such as prevailing economic conditions and changes in regulations, and Ortho cannot assure you that it will be able to comply with such covenants. These restrictions also limit Ortho’s ability to obtain future financings to withstand a future downturn in Ortho’s business or the economy in general. In addition, complying with these covenants may also cause Ortho to take actions that are not favorable to holders of its ordinary shares and may make it more difficult for Ortho to successfully execute its business strategy and compete against companies that are not subject to such restrictions.

72

In addition, the financial covenant in the Credit Agreement requires the maintenance of a maximum first lien leverage ratio, which ratio will be tested when it yields more than 30% at the end of any quarter when borrowings under the Revolving Credit Facility (including swingline loans and any unreimbursed drawings under any letters of credit to the extent not cash-collateralized but excluding any guarantees and performance or similar bonds issued under Ortho’s Revolving Credit Facility) exceed $105 million at such date. As of January 2, 2022, Ortho had no borrowings outstanding under the Revolving Credit Facility and was therefore not subject to the financial covenant. Due to the current economic and business uncertainty resulting from the ongoing COVID-19 pandemic, Ortho anticipates that Ortho will maintain increased cash on hand in order to preserve financial flexibility and that, as a result, Ortho may continue to borrow from Ortho’s Revolving Credit Facility, if needed. Ortho’s ability to meet the financial covenant could be affected by events beyond Ortho’s control.

A breach of the covenants under the Credit Agreement, the 2025 Notes Indenture or the 2028 Notes Indenture could result in an event of default under the applicable indebtedness. Such a default, if not cured or waived, may allow the creditors to accelerate the related debt and may result in the acceleration of any other debt that is subject to an applicable cross-acceleration or cross-default provision. In addition, an event of default under the Credit Agreement would permit the lenders under Ortho’s Senior Secured Credit Facilities to terminate all commitments to extend further credit under the facilities. Furthermore, if Ortho were unable to repay the amounts due and payable under Ortho’s Senior Secured Credit Facilities, those lenders could proceed against the collateral securing such indebtedness. In the event Ortho’s lenders or holders of the Senior Notes accelerate the repayment of Ortho’s borrowings, Ortho and its subsidiaries may not have sufficient assets to repay that indebtedness.

Despite Ortho’s level of indebtedness, Ortho and its subsidiaries may still incur substantially more debt. This could further exacerbate the risks to Ortho’s financial condition described above and impair Ortho’s ability to operate its business.

Ortho and its subsidiaries may incur significant additional indebtedness in the future. Although the Credit Agreement, the 2025 Notes Indenture and the 2028 Notes Indenture contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions, including with respect to Ortho’s ability to incur additional senior secured debt. The additional indebtedness Ortho may incur in compliance with these restrictions could be substantial. These restrictions also will not prevent Ortho from incurring obligations that do not constitute indebtedness. In addition, as of January 2, 2022, our Revolving Credit Facility provides for unused commitments of $453.7 million (net of $46.3 million of outstanding letters of credit). On February 5, 2021, we entered into a Fifth Amendment of our Senior Secured Credit Facilities (the “Fifth Amendment”), which increased our Revolving Credit Facility contained in the Credit Agreement by $150.0 million to an aggregate principal amount of $500.0 million and extended the maturity date to February 5, 2026, provided that such date may be accelerated subject to certain circumstances as set forth in the Fifth Amendment. To the extent that the aggregate principal amount of the Dollar Term Loan Facility and Euro Term Loan Facility (and any Refinancing Indebtedness with respect thereto that matures on or prior to June 30, 2025) outstanding as of March 31, 2025 exceeds $500.0 million then the maturity date with respect to the Revolving Credit Facility shall be March 31, 2025. All other terms of the Senior Secured Credit Facilities will remain substantially the same except as otherwise amended by the Fifth Amendment. Ortho’s Senior Secured Credit Facilities may be increased by an amount equal to (x) a dollar amount of $375.0 million (which amount was utilized in connection with Ortho’s incurrence of the Euro Term Loan Facility), plus (y) an unlimited amount so long as on a pro forma basis Ortho’s First Lien Net Leverage Ratio (as set forth in the Credit Agreement) does not exceed 4.00 to 1.00 plus (z) an amount equal to all voluntary prepayments of term loans borrowed under the Credit Agreement and revolving loans under the Credit Agreement to the extent accompanied by a permanent reduction in the commitments therefor, subject to certain conditions. If new debt is added to Ortho’s current debt levels, the related risks that Ortho now faces would increase.

General Risks Relating to Ortho

The insurance Ortho maintains may not fully cover all potential exposures.

Ortho’s product liability, property, business interruption, cybersecurity, casualty and other insurance may not cover all risks associated with the operation of Ortho’s business and may not be sufficient to offset the costs of any losses, lost sales or increased costs experienced during business interruptions. For some risks, Ortho may not obtain insurance if Ortho believes the cost of available insurance is excessive related to the risks presented. As a result of market conditions, premiums and deductibles for certain insurance policies can increase substantially and, in some instances, certain insurance policies may become unavailable or available only for reduced amounts of coverage. As a result, Ortho may not be able to renew Ortho’s

73

insurance policies or procure other desirable insurance on commercially reasonable terms, if at all. Losses and liabilities from uninsured or underinsured events and delay in the payment of insurance proceeds could have a material adverse effect on Ortho’s financial condition and results of operations.

Terrorist acts, conflicts, wars and natural disasters may materially adversely affect Ortho’s business, financial condition and results of operations.

As a multinational company with a large international footprint, Ortho is subject to increased risk of damage or disruption to it, its employees, facilities, partners, suppliers, distributors, resellers or customers due to terrorist acts, conflicts, wars, adverse weather conditions, natural disasters, power outages, pandemics or other public health crises and environmental incidents, wherever located around the world. The potential for future terrorist attacks and natural disasters, the national and international responses to such attacks and natural disasters or perceived threats to national security and other actual or potential conflicts or wars may create economic and political uncertainties. In addition, as a multinational company with headquarters and significant operations located in the United States, actions against or by the United States could result in a decrease in demand for Ortho’s products, make it difficult or impossible to deliver products to Ortho’s customers or to receive components from Ortho’s suppliers, create delays and inefficiencies in Ortho’s supply chain and pose risks to Ortho’s employees, resulting in the need to impose travel restrictions. Any interruption in production capability could require Ortho to make substantial capital expenditures to remedy the situation, which could negatively affect Ortho’s profitability and financial condition.

Ortho is subject to work stoppages, union negotiations, labor disputes and other matters associated with its labor force, which may adversely impact Ortho’s operations and cause Ortho to incur incremental costs.

Ortho has more than 4,800 employees located around the world consisting of commercial, supply chain, quality, regulatory and compliance, research and development and general administrative personnel. Approximately 20% of Ortho’s associates globally participate in a union or works council. Historically, Ortho has not experienced work stoppages; however, in the future, Ortho may be subject to potential union campaigns, work stoppages, union negotiations and other potential labor disputes. Additionally, future negotiations with unions or works councils in connection with existing labor agreements may (i) result in significant increases in Ortho’s cost of labor, (ii) divert management’s attention away from operating Ortho’s business or (iii) break down and result in the disruption of Ortho’s operations. The occurrence of any of the preceding outcomes could impair Ortho’s ability to manufacture Ortho’s products and result in increased costs and/or decreased operating results. Further, Ortho may be subject to work stoppages at Ortho’s suppliers or customers that are beyond Ortho’s control.

If Ortho is required to make unexpected payments to any pension plans applicable to Ortho’s employees, Ortho’s financial condition may be adversely affected.

Some of Ortho’s current and former employees participate or participated in defined benefit pension plans and Ortho assumed certain underfunded and unfunded net pension liabilities of approximately $40.0 million in relation to these plans. Several of these plans are unfunded and, while Ortho does not believe the liabilities in relation to these plans are significant, they will need to be satisfied as they mature from Ortho’s cash provided by operating activities. In jurisdictions where the defined benefit pension plans are intended to be funded with assets in a trust or other funding vehicle, Ortho expects that, while not significant, the liabilities will exceed the corresponding assets in each of the plans. Various factors, such as changes in actuarial estimates and assumptions (including in relation to life expectancy, discount rates and rate of return on assets), as well as actual return on assets, can increase the expenses and liabilities of the defined benefit pension plans. The assets and liabilities of the plans must be valued from time to time under applicable funding rules and as a result Ortho may be required to increase the cash payments it makes in relation to these defined benefit pension plans.

Ortho could also be required in some jurisdictions to make accelerated payments up to the full buy-out deficit in Ortho’s defined benefit pension plans, which would likely be far higher than the normal ongoing funding cost of the plans. Ortho’s operations and financial condition may be adversely affected to the extent that Ortho is required to (i) make any additional payments to any relevant defined benefit pension plans in excess of the amounts assumed in Ortho’s current projections and assumptions or (ii) report higher pension plan expenses under relevant accounting rules.

74

If Ortho is sued for infringing intellectual property rights of third parties, it will be costly and time-consuming, and an unfavorable outcome in any litigation would harm Ortho’s business.

Ortho cannot assure you that its activities will not, unintentionally or otherwise, infringe on the patents or other intellectual property rights owned by others. Significant litigation regarding patent rights exists in Ortho’s industry. Ortho’s competitors in both the United States and foreign countries, many of which have substantially greater resources and have made substantial investments in competing technologies, may have applied for or obtained, or may in the future apply for and obtain, patents that will prevent, limit or otherwise interfere with Ortho’s ability to make and sell its products. Ortho may spend significant time and effort and incur significant litigation costs if it is required to defend itself against intellectual property rights claims brought against it, regardless of whether the claims have merit. If Ortho is found to have infringed on the patents or other intellectual property rights of others, Ortho may be subject to substantial claims for damages, which could materially impact its cash flow, business, financial condition and results of operations. Ortho may also be required to cease development, use or sale of the relevant products or processes, or Ortho may be required to obtain a license on the disputed rights, which may not be available on commercially reasonable terms, if at all, or may require Ortho to re-design Ortho’s products or processes.

Ortho will incur increased costs as a result of operating as a publicly traded company, and Ortho’s management will be required to devote substantial time to new compliance initiatives.

As a publicly traded company, Ortho incurs additional legal, accounting and other expenses that it did not previously incur, which may be material in amount. In addition, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act and the rules of the SEC, and the stock exchange on which Ortho’s ordinary shares are listed, have imposed various requirements on public companies. Ortho’s management and other personnel will need to devote a substantial amount of time to these compliance initiatives as well as investor relations. Moreover, these rules and regulations will increase Ortho’s legal and financial compliance costs and will make some activities more time-consuming and costly. For example, Ortho expects these rules and regulations to make it more difficult and more expensive for Ortho to obtain director and officer liability insurance, and Ortho may be required to incur additional costs to maintain the same or similar coverage.

UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

On December 22, 2021, Quidel Corporation (“Quidel”) entered into a Business Combination Agreement (the “BCA”) by and among Quidel, Ortho Clinical Diagnostics Holdings plc (“Ortho”), Coronado Topco, Inc. (“Topco”), Orca Holdco, Inc. (“U.S. Holdco Sub”) and Laguna Merger Sub, Inc. (“U.S. Merger Sub”), each wholly owned subsidiaries of Topco, and Orca Holdco 2, Inc., a wholly owned subsidiary of U.S. Holdco Sub, which provides for the acquisition of Ortho and Quidel by Topco.

The following unaudited pro forma combined financial information, which is referred to in this joint proxy statement/prospectus as the unaudited pro forma financial information, is presented to illustrate the estimated effects of the transactions to be implemented pursuant to the BCA (the “Combinations”) based on the historical financial statements and accounting records of Quidel and Ortho after giving effect to the Combinations, and the Combinations-related pro forma adjustments as described in the accompanying notes to the unaudited pro forma financial information.

The fiscal year of each of Quidel and Ortho ends on the Sunday nearest December 31 of the specified period. For ease of reference, the calendar year end dates are used herein. The following unaudited pro forma combined balance sheet was prepared based on the following historical dates: (i) the audited historical consolidated balance sheet of Quidel as of December 31, 2021 and (ii) the audited historical consolidated balance sheet of Ortho as of December 31, 2021.

The following unaudited pro forma combined statement of income for the fiscal year ended December 31, 2021 was prepared based on the following historical periods: (i) the audited historical consolidated statement of income of Quidel for the year ended December 31, 2021 and (ii) the audited historical consolidated statement of operations of Ortho for the year ended December 31, 2021.

The following unaudited pro forma combined financial information has been prepared to reflect the Combinations and is provided for illustrative purposes only. The unaudited pro forma combined statements of income assume that the Combinations occurred on January 1, 2021, the beginning of the earliest period presented, but do not necessarily reflect what Topco’s results of operations would have been had the Combinations been completed on January 1, 2021, or for any future or historical period. The unaudited pro forma combined balance sheet assumes that the Combinations occurred on December 31, 2021, but does not necessarily reflect what Topco’s financial position would have been had the Combinations been completed on December 31, 2021, or for any future or historical period.

The unaudited pro forma financial information was prepared using the acquisition method of accounting with Quidel treated as the accounting acquirer and, therefore, the historical basis of Quidel’s assets and liabilities was not affected by the Combinations. The pro forma financial statements should be read in conjunction with the information contained in the sections entitled “The Combinations,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations of Ortho” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations of Quidel” of this joint proxy statement/prospectus and the historical consolidated financial statements and related notes appearing elsewhere in, or incorporated in, this joint proxy statement/prospectus.

As of the date of this joint proxy statement/prospectus, Quidel has not completed the detailed valuation studies necessary to arrive at the final estimates of the fair market value of the Ortho assets to be acquired and the liabilities to be assumed and the related allocations of purchase price, nor has it identified any adjustments necessary to conform Ortho to Quidel’s accounting policies except for the ones described in the accompanying notes. The acquisition method of accounting is dependent upon certain valuations that are provisional and subject to change. Accordingly, the pro forma adjustments in the unaudited pro forma combined financial information are preliminary based upon available information and made solely for the purpose of providing these unaudited pro forma combined financial statements.

The unaudited pro forma financial information has not been adjusted to give effect to certain expected financial benefits of the Combinations, such as revenue synergies, tax savings and cost synergies, or the anticipated costs to achieve these benefits, including the cost of integration activities. The unaudited pro forma financial information does not purport to represent what the actual consolidated results of operations or the consolidated financial position of Topco would have been had the Combinations occurred on the dates indicated, nor is it necessarily indicative of Topco’s future consolidated results of operations or consolidated financial position. The actual financial position and results of operations will differ, potentially significantly, from the pro forma amounts reflected herein due to a variety of factors, including access to additional information, changes in value not currently identified and changes in operating results following the date of the unaudited pro forma financial information. Accordingly, actual adjustments to Topco’s financial statements following the acquisition could

76

differ, perhaps materially, from those reflected in the unaudited pro forma condensed combined financial information because the purchase price is subject to changes in the Quidel Share price on the acquisition date, and assets and liabilities acquired and share-based compensation awards will be recorded at their respective fair values on the date the acquisition is consummated.

NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

1. Description of the proposed Combinations

On December 22, 2021, Quidel entered into the BCA by and among Quidel, Ortho, Topco, U.S. Holdco Sub and U.S. Merger Sub, each wholly owned subsidiaries of Topco, and Orca Holdco 2, Inc., a wholly owned subsidiary of U.S. Holdco Sub, which provides for the acquisition of Ortho and Quidel by Topco. The Combinations are expected to be implemented by way of (i) a scheme of arrangement to be undertaken by Ortho under Part 26 of the UK Companies Act 2006 (the “Ortho Scheme”), pursuant to which each issued and outstanding share of Ortho (the “Ortho Shares”) will be acquired by a nominee of Topco (or, if such nominee holds the Ortho Shares today, transferred within the nominee), such that Ortho will become a wholly owned subsidiary of Topco, and (ii) a merger (the “Quidel Merger”) of U.S. Merger Sub with and into Quidel immediately following consummation of the Ortho Scheme, with Quidel surviving the merger as a wholly owned subsidiary of Topco. At the effective time of the Ortho Scheme (the “Ortho Effective Time”), each Ortho Share, other than Ortho Shares held by Ortho in treasury, will be acquired by a nominee (or, if such nominee holds the Ortho Shares today, transferred within the nominee) on behalf and for the benefit of Topco in exchange for 0.1055 shares (the “Ortho Exchange Ratio”) of common stock of Topco (“Topco Shares”) and $7.14 in cash (collectively, the “Ortho Scheme Consideration”). At the effective time of the Quidel Merger (the “Quidel Effective Time” and together with the Ortho Effective Time, the “Effective Times”), each share of common stock of Quidel (each, a “Quidel Share”), other than Quidel Shares held by Quidel, Ortho or U.S. Merger Sub, will be converted into the right to receive one Topco Share (the “Quidel Exchange Ratio”) (the “Quidel Merger Consideration” and together with the Ortho Scheme Consideration, the “Combination Consideration”). Topco will apply to list the Topco Shares to be issued in the Combinations on the Nasdaq Global Select Market (“Nasdaq”).

At the Ortho Effective Time, each option to subscribe for Ortho Shares (each, an “Ortho Stock Option”), whether vested or unvested, that is outstanding immediately prior the Ortho Effective Time will cease to represent an option to acquire Ortho Shares and will be converted into (a) an option to purchase Topco Shares (each, a “Topco Stock Option”) on the same terms and conditions as were applicable to such Ortho Stock Option immediately prior to the Ortho Effective Time, except as adjusted by the BCA, (b) with respect to the portion of such Ortho Stock Option that is vested as of the Ortho Effective Time, the right to receive payment, in cash, equal to the cash consideration payable in respect of the Ortho Shares subject to the vested portion of such Ortho Stock Option and (c) with respect to the portion of such Ortho Stock Option that is not vested as of the Ortho Effective Time, the right to receive payment, in cash, equal to the cash consideration payable in respect of the Ortho Shares subject to the unvested portion of such Ortho Stock Option when it vests in accordance with its terms. The number of Topco Shares subject to each such Topco Stock Option will be equal to the product (rounded down to the nearest whole number) obtained by multiplying (i) the number of Ortho Shares subject to such Ortho Stock Option immediately prior to the Ortho Effective Time by (ii) the Ortho Exchange Ratio, and each such Topco Stock Option will have an exercise price per share (rounded up to the nearest whole cent) equal to (x) the exercise price per Ortho Share of such Ortho Stock Option immediately prior to the Ortho Effective Time divided by (y) the Ortho Exchange Ratio.

At the Ortho Effective Time, each award of restricted stock, restricted stock units or other similar rights or awards granted under an Ortho stock plan and relating to Ortho Shares (any such award, an “Ortho Equity Right” and such awards together with the Ortho Stock Options, the “Ortho Stock Awards”) that is outstanding immediately prior to the Ortho Effective Time will cease to relate to or represent a right to receive Ortho Shares and will be converted into an award of restricted stock, restricted stock units or other similar rights or awards, as applicable, relating to Topco Shares (a “Topco Equity Right”) of the same type and on the same terms and conditions as were applicable to the corresponding Ortho Equity Right immediately prior to the Ortho Effective Time. Upon the subsequent vesting of any portion of such Ortho Equity Right, such portion of the Ortho Equity Right shall also be entitled to a right to receive payment, in cash, equal to the cash consideration in respect of the Ortho Shares subject to the unvested portion of the Ortho Equity Right when it vests in accordance with its terms. The number of Topco Shares covered by each such Topco Equity Right will be equal to the product (rounded to the nearest whole number) obtained by multiplying (i) the number of Ortho Shares subject to such Ortho Equity Right immediately prior to the Ortho Effective Time by (ii) the Ortho Exchange Ratio. See estimated preliminary purchase price discussed further in Note 3.

Furthermore, all of Quidel’s outstanding share-based compensation will be replaced with similar Topco awards as described in the section entitled “The Business Combination Agreement—Treatment of Quidel Equity Awards.”

Under the terms of the BCA, which was unanimously approved by the board of directors of each of Quidel and Ortho, Quidel and Ortho are entering into a business combination under Topco, a new holding company, in which Ortho will be acquired for total consideration of approximately $4.3 billion (which is based on the March 4, 2022 closing price of $99.57 per Quidel

80

Share, as described in further detail below), including $1.74 billion of cash, funded through cash on the balance sheet and expected incremental borrowings. Such consideration was equal to $6.0 billion based on the December 22, 2021 closing price of the Quidel Shares, and is subject to change based on the price of a Quidel Share. Topco is also expected to be subject to Ortho’s existing debt of $2.2 billion. If the Combinations are completed, Ortho shareholders are expected to own approximately 38% of Topco on a fully diluted basis and Quidel stockholders are expected to own approximately 62% of Topco on a fully diluted basis, based on the respective capitalizations of Quidel and Ortho as of the date the parties entered into the BCA.

2. Basis of pro forma presentation

The accompanying unaudited pro forma combined financial information was prepared in accordance with Article 11 of the SEC’s Regulation S-X. The historical financial statements were prepared in accordance with U.S. GAAP and presented in thousands of U.S. dollars.

The Combinations will be accounted for as a business combination using the acquisition method of accounting under the provisions of ASC Topic 805, “Business Combinations” (“ASC 805”), and using the fair value concepts defined in ASC Topic 820, “Fair Value Measurements” (“ASC 820”). ASC 820 defines the term “fair value” and sets forth the valuation requirements for any asset or liability measured at fair value, expands related disclosure requirements and specifies a hierarchy of valuation techniques based on the nature of the inputs used to develop fair value measures. Fair value is defined in ASC 820 as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” This is an exit price concept for the valuation of the asset or liability. In addition, market participants are assumed to be buyers and sellers in the principal (or the most advantageous) market for the asset or liability. Many of these fair value measurements can be highly subjective, and it is possible that other professionals, applying reasonable judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts. Under ASC 805, all assets acquired and liabilities assumed are recorded at their acquisition date fair value.

Fair value estimates were determined based on preliminary discussions between Quidel’s and Ortho’s management, due diligence efforts, and information available in public filings. The allocation of the aggregate Combination Consideration used in the preliminary unaudited pro forma combined financial information is based on preliminary estimates. The estimates and assumptions are subject to change as of the Effective Times. The final determination of the allocation of the aggregate Combination Consideration will be based on the actual tangible assets, intangible assets, deferred tax assets, deferred tax liabilities and liabilities of Ortho at the Effective Times.

For pro forma purposes, the valuation of consideration transferred is based on, among other things, the closing price of Quidel Shares on March 4, 2022 of $99.57 per share. This is used for pro forma purposes only. The consideration transferred will ultimately be based on the price of Quidel Shares at the Effective Times of the Combinations and could materially change.

Significant accounting policies

The unaudited pro forma combined financial information has been compiled in a manner consistent with the accounting policies adopted by Quidel. Based on the procedures performed to date, the accounting policies of Ortho appear to be similar in all material respects to Quidel’s accounting policies. Upon completion of the Combinations, Quidel will perform a detailed review of Ortho’s accounting policies. As a result of that review, Quidel may identify additional differences between the accounting policies of the two companies that, when conformed, could have a material impact on the consolidated financial statements of Topco.

3. Preliminary Purchase Price

Ortho shareholders will receive 0.1055 Topco Shares and $7.14 in cash per Ortho Share as purchase consideration in connection with the Combinations as discussed above; however, because Quidel is the accounting acquirer and Ortho is the acquiree for accounting purposes, the unaudited pro forma financial information reflects the estimated fair value of the equity to be issued, as represented by the market price of Quidel Shares, to Ortho shareholders. The total purchase consideration to be received by Ortho shareholders will be based on the fair value of the equity deemed to be issued at the Effective Times of the Combinations. The preliminary purchase consideration below reflects the estimated fair value of equity issued, which is

81

based on the March 4, 2022 closing price of Quidel Shares of $99.57 per share. The amount of total purchase consideration below is not necessarily indicative of the actual consideration that will be transferred at the Effective Times of the Combinations to Ortho shareholders as a result of potential changes to the price per Quidel Share.

The preliminary estimated purchase consideration and estimated fair value of Ortho’s net assets acquired as if the Combinations closed on December 31, 2021 is presented as follows:

(In thousands, except value per share data and Ortho Exchange Ratio) |  |  |
Total Ortho Shares subject to exchange |  |  | 236,815 |
Ortho Exchange Ratio |  |  | 0.1055 |
Topco Shares to be issued |  |  | 24,984 |
Value per Quidel Share as of March 4, 2022 |  | $ | 99.57 |
Estimated value of stock consideration |  | $ | 2,487,657 |
Fair value of replacement stock awards (1) |  |  | 50,098 |
Cash consideration (2) |  |  | 1,742,946 |
Estimated purchase consideration |  | $ | 4,280,701 |

(1) | Represents estimated fair value of replacement stock options, restricted stock units and restricted stock outstanding as of December 31, 2021 that is attributable to pre-combination service. Management is in the process of evaluating the expected impact of replacement stock awards subsequent to the Combinations. The portion of the fair value of the replacement stock awards attributable to post-combination service will be recognized as compensation expense based on the vesting terms of the replacement stock awards.

(2) | Represents cash consideration to be paid to outstanding Ortho shareholders and to vested Ortho Stock Option holders at the Ortho Effective Time.

|  | Shares |  |  | Cash Per share |  |  | Total |
Number of Ortho Shares outstanding |  |  | 236,815 |  |  | $ | 7.14 |  |  | $ | 1,690,860 |
Vested Ortho Stock Options |  |  | 7,295 |  |  | $ | 7.14 |  |  |  | 52,086 |
Total cash consideration |  |  |  |  |  |  |  |  |  | $ | 1,742,946 |

The estimate of consideration expected to be transferred reflected in these unaudited pro forma combined financial statements does not purport to represent what the actual consideration transferred will be when the Combinations are consummated. For purposes of these unaudited pro forma combined financial statements, the market price of Quidel Shares on March 4, 2022 and outstanding Ortho Shares as of December 31, 2021 was used to calculate the estimate of consideration expected to be transferred. However, the fair value of equity securities issued as the consideration transferred will be measured using the market price of Quidel Shares and outstanding Ortho Shares on the closing date of the Combinations. An increase/decrease of 10% in the price of Quidel Shares would increase/decrease the total consideration by $248.8 million, which would be reflected in these unaudited pro forma combined financial statements as an increase or decrease to goodwill. The estimated fair value of replacement equity awards is subject to change until the Effective Times of the Combinations due to equity awards vesting, grants or forfeitures. The estimated cash consideration was calculated using outstanding Ortho Shares and vested Ortho Stock Options as of December 31, 2021. The cash consideration at the closing of the Combinations will fluctuate due to changes in outstanding shares and vesting, grants or forfeitures of Ortho Stock Awards.

Under the acquisition method of accounting, the Ortho assets and liabilities will be recorded at fair value at the date of the completion of the Combinations and combined with the historical carrying amount of the assets and liabilities of Quidel. The pro forma adjustments are preliminary and based on estimates of the fair value and useful lives of the assets as of December 31, 2021 and have been prepared by Quidel management and Ortho management to illustrate the estimated effect of the Combinations. The unaudited pro forma financial information does not include any fair value adjustments associated with the assets and liabilities of Ortho with the exception of the fair value of long-term borrowings, inventories, and intangible assets, as Quidel and Ortho management have based the preliminary purchase accounting on the assumption that these historical carrying values approximate their fair values as of December 31, 2021. The purchase accounting is dependent upon certain valuation and other analyses that have not yet been completed. Accordingly, the preliminary purchase accounting is subject to further adjustments as additional information becomes available and as additional analyses and final valuations are conducted at and following the completion of the Combinations. The final

82

valuations could differ materially from the preliminary valuations presented below and, accordingly, no assurances can be provided regarding the preliminary purchase accounting.

The following table summarizes the preliminary purchase accounting consideration to the identifiable assets acquired and liabilities assumed of Ortho, with the excess of the purchase consideration issued over the fair value of Ortho’s net assets recorded as goodwill (in thousands):

Cash and cash equivalents |  | $ | 309,700 |
Accounts receivable, net |  |  | 257,200 |

5. Transaction Accounting Adjustments for Pro Forma Combined Balance Sheet

The following represents an explanation of the various adjustments to the unaudited pro forma combined balance sheet.

(a) Cash and cash equivalents

Represents a net decrease in cash of $1.0 billion due to $1.7 billion of aggregate cash consideration paid to Ortho shareholders under the BCA and $15.0 million of estimated financing costs associated with expected borrowings offset by $750.0 million from proceeds to be received from Quidel’s presumed borrowings.

86

(b) Inventories

Represents an adjustment of $68.9 million to Inventories to reflect the estimated step-up in fair value of Ortho’s inventory acquired, valued using a comparative sales method. The calculated value is preliminary and subject to change and could vary materially from the final purchase price allocation.

(c) Property, plant and equipment, net

Quidel has not yet determined the fair value of property, plant and equipment to be acquired; therefore, the historical carrying value has been used in the preliminary purchase price allocation reflected in the unaudited pro forma combined balance sheet. The fair value could be materially different from the historical carrying value. This assertion remains contingent upon receiving additional information and performing procedures to calculate the fair value of property, plant and equipment. No adjustment was made to the unaudited pro forma combined statements of income, but any difference between the fair value and the historical carrying value would have a direct impact on future earnings via depreciation expense.

(d) Goodwill

Reflects adjustments to remove $573.6 million of historical Ortho goodwill and recognize preliminary estimated goodwill of $2.3 billion. Goodwill represents the excess of the purchase price over the preliminary fair value of Ortho’s underlying net tangible and identifiable intangible assets net of liabilities. The goodwill created in the Combinations is not expected to be deductible for tax purposes and is subject to material revision as the purchase price allocation is completed.

(e) Intangible Assets

Represents adjustments to record the preliminary estimated fair value of Ortho’s intangible assets of approximately $3.5 billion, which is an increase of $2.6 billion over Ortho’s book value of intangible assets prior to the Combinations. The acquired identifiable intangible assets are expected to be comprised of definite-lived customer relationships, developed technology, and trade names related to various Ortho products.

The fair value of intangible assets and related amortization are preliminary and are based on management’s assessment of comparable industry transactions. As discussed above, the amount that will ultimately be allocated to identifiable intangible assets and the related amount of amortization may differ materially from this preliminary allocation. In addition, the periods the amortization impacts will ultimately be based upon the periods in which the associated economic benefits or detriments are expected to be derived, or where appropriate, based on the use of a straight-line method. Therefore, the amount of amortization following the Combinations may differ significantly between periods based upon the final value assigned and amortization methodology used for each identifiable intangible asset.

(f) Deferred tax asset and liability

Represents the removal of $9.7 million of Ortho deferred tax asset and the removal of $72.1 million of Ortho deferred tax liability previously recorded. After giving effect to the estimated impact of the Combinations and the release of Ortho’s U.S. valuation allowance of $381.1 million, $34.9 million of deferred tax assets, $268.3 million of U.S. net deferred tax liabilities and $257.6 million of foreign deferred tax liabilities were recorded. This estimate of deferred tax assets and liabilities is preliminary and is subject to change based upon the final determination of fair value of assets acquired and liabilities assumed, which could be materially different.

(g) Other non-current assets

Represents the adjustment to remove $2.7 million of capitalized financing costs related to Ortho’s revolving line of credit in connection with the fair value adjustment for purchase accounting.

87

(h) Accrued payroll and related expenses and Other current liabilities

Represents the pro forma adjustments to Accrued payroll and related expenses and Other current liabilities of $15.1 million and $92.7 million, respectively. Refer to the tables below which reflect the components of Accrued payroll and related expenses and Other current liabilities impacted by pro forma adjustments, which reflect retention and transaction costs expected to be incurred and not previously recognized in the historical balance sheets (in thousands):

Quidel retention costs |  | $ | 8,000 |
Ortho retention costs |  |  | 7,130 |
Net increase to accrued payroll and related expenses |  | $ | 15,130 |

Quidel transaction costs |  | $ | 45,300 |
Ortho transaction costs |  |  | 47,400 |
Net increase to other current liabilities |  | $ | 92,700 |

(i) Current and Long-term borrowings

Represents the net pro forma increase to long-term borrowings of $803.7 million. Refer to the table below which reflects the components of debt impacted by pro forma adjustments (in thousands):

Ortho debt fair value adjustment (1) |  | $ | 42,036 |
Removal of Ortho original issue discount and deferred financing fees |  |  | 26,666 |
New Quidel borrowings (2) |  |  | 750,000 |
Financing fees related to new Quidel borrowings |  |  | (15,000 | )
Net increase in Long-term borrowings |  | $ | 803,702 |

| (1) | Represents the estimated fair value adjustment increase of $42.0 million related to Ortho’s historical long-term borrowings. The fair value of Ortho’s debt was determined based on trades as reported by a third-party bond pricing service.

| (2) | Represents presumed issuance of new Quidel debt for the purposes of financing a portion of the cash consideration discussed in Note 5a.

(j) Preferred and Common Stock

The preferred redeemable shares are redeemable for no consideration under the BCA and have been removed as part of the Combinations adjustments. The par value of Ortho historical common stock was immaterial. The net adjustment to common stock reflects the par value for the issuance of Topco Shares in exchange for Ortho Shares calculated by multiplying the number of shares to be exchanged (see Note 3) by the $0.001 par value of Topco Shares (in thousands, except Ortho Exchange Ratio and per share data):

Number of Ortho Shares outstanding at December 31, 2021 |  |  | 236,815 |
Ortho Exchange Ratio |  |  | 0.1055 |
Topco Shares issued in connection with the Combinations |  |  | 24,984 |
Par value per Topco Share |  |  | 0.001 |
Net adjustment for par value of Topco Shares |  | $ | 25 |

88

(k) Additional paid-in capital

Represents the elimination of Ortho historical additional paid-in capital, as well as reflecting the excess of fair value over par value for the issuance of common stock and the fair value of acquired stock awards (in thousands):

Fair value of Combinations stock consideration |  | $ | 2,487,657 |
Fair value of Ortho Stock Awards |  |  | 50,098 |
Less: par value of Topco Shares |  |  | (25 | )
Elimination of historical Ortho additional paid-in capital |  |  | (2,425,900 | )
Net adjustment to additional paid-in capital |  | $ | 111,830 |

(l) Accumulated other comprehensive loss

Represents the elimination of $43.7 million of historical accumulated other comprehensive loss of Ortho.

(m) Retained earnings (accumulated deficit)

Represents the pro forma adjustment to retained earnings of $1.9 billion. Refer to the table below which reflects the components of retained earnings (accumulated deficit) impacted by pro forma adjustments (in thousands):

Elimination of Ortho’s historical accumulated deficit |  | $ | 1,971,800 |
Quidel transaction costs (1) |  |  | (45,300 | )
Ortho transaction costs (1) |  |  | (47,400 | )
Quidel retention costs (2) |  |  | (8,000 | )
Ortho retention costs (2) |  |  | (7,130 | )
Net adjustment to retained earnings (accumulated deficit) |  | $ | 1,863,970 |

| (1) | Reflects an estimate of Quidel’s and Ortho’s non-recurring transaction-related costs. Transaction costs related to the Combinations include advisory, banking, and legal fees. These amounts will be expensed as incurred and are also reflected in the unaudited pro forma combined statement of income for the year ended December 31, 2021 (See Note 6(c)).

| (2) | Reflects an estimate of Quidel’s and Ortho’s non-recurring retention-related costs. Retention costs related to the Combinations include employee compensation charges. These amounts will be expensed as incurred and are also reflected in the unaudited pro forma combined statement of income for the year ended December 31, 2021 (See Note 6(c)).

6. Transaction Accounting Adjustments for Pro Forma Combined Statement of Income

The following outlines the various adjustments to the unaudited pro forma combined statement of income.

(a) Cost of revenue

Reflects an adjustment to record an estimate of $68.9 million in the year ended December 31, 2021 resulting from the unwinding of the estimated step-up in fair value of inventory acquired. This adjustment will not affect the combined statement of income beyond twelve months after the acquisition date.

(b) Amortization of intangible assets

Reflects the adjustments to record new amortization expense based on the fair value of the preliminary estimate of acquired intangible assets, which represents the portion of the purchase price allocated to Ortho’s definite-lived developed technology, customer relationships and trade names. The preliminary estimated useful lives is 15 years for developed technology and trade names and 20 years for customer relationships.

For the year ended December 31, 2021, represents a net increase of $62.8 million from the elimination of historical Ortho intangible asset amortization of $133.4 million and the recognition of pro forma amortization expense of $196.2 million.

89

Amortization expense has been calculated on a preliminary basis, using the straight-line method over the estimated useful lives. The effect of a 10% increase or decrease in preliminary estimated fair value would result in an increase or decrease of amortization expense of $19.6 million for the year ended December 31, 2021.

(c) Acquisition and integration costs

Reflects adjustments to record estimates of $92.7 million, $27.1 million and $12.8 million in the year ended December 31, 2021 for nonrecurring transaction-related costs, retention-related costs and an estimate of post-combination expense related to the acceleration of employee unvested stock awards, respectively, not already incurred in the historical statements of operations for the year ended December 31, 2021 for Quidel and Ortho in connection with the Combinations. The transaction-related costs will include advisory, banking, and legal fees and the retention-related costs will include employee compensation charges.

(d) Interest expense

Represents the assumed net increase in interest expense related to Quidel’s new borrowings of $750.0 million, the elimination of the amortization of Ortho deferred financing fees and debt discounts, and the amortization of the premium associated with the fair value adjustment to debt as follows (in thousands):

|  | Year ended December 31, 2021 |
Elimination of the amortization of deferred financing fees and discounts (1) |  | $ | (8,000 | )
Amortization of premium associated with the fair value adjustment to debt (2) |  |  | (6,900 | )
Interest expense related to the issuance of new Quidel debt |  |  | 33,750 |
Amortization of financing fees associated with new Quidel debt |  |  | 3,000 |
Net increase in interest expense |  | $ | 21,850 |

| (1) | Represents an adjustment to eliminate the historical amortization of Ortho deferred financing fees and discounts recognized through interest expense.

| (2) | Represents the annual incremental amortization of the premium related to the fair value adjustment increase of $42.0 million related to Ortho’s historical long-term debt.

(e) Income tax expense

Represents the income tax effect of unaudited pro forma combined statement of income adjustments related to the Combinations using a federal and state combined statutory tax rate of 23% estimated based upon the federal and state combined statutory tax rates. Because the adjustments contained in this unaudited pro forma combined financial information are based on estimates, the effective tax rate will likely vary from the effective rate in periods subsequent to the Combinations. Adjustments to established deferred tax assets and liabilities as well as the recognition of additional deferred tax assets and liabilities upon detailed analysis of the acquired assets and assumed liabilities may occur in conjunction with the finalization of the purchase accounting, and these items could be material.

(f) Earnings per share

The unaudited pro forma condensed combined basic and diluted earnings per share calculations are based on the combined basic and diluted weighted average shares, after giving effect to the Ortho Exchange Ratio and the Quidel Exchange Ratio. The historical basic and diluted weighted average shares of Ortho are assumed to be replaced by the shares expected to be issued by Topco to effect the Combinations, as follows (in thousands, except share and per share amounts):

|  | For the year ended |
|  | December 31, 2021 |
Pro forma net income |  | $ | 452,915 |
Historical Quidel basic weighted-average shares outstanding |  |  | 42,078 |
Issuance of Topco Shares to Ortho shareholders |  |  | 24,984 |

SCHEME PROPOSAL AND THE ORTHO SHAREHOLDER MEETINGS— EXPLANATORY STATEMENT

(In compliance with Section 897 of the UK Companies Act 2006)

[●], 2022

To the holders of Ortho Shares and, for information only, to the holders of options or awards under any Ortho Clinical Diagnostics Holdings plc employee benefit plan providing for equity or equity-based compensation.

RECOMMENDED ACQUISITION OF ORTHO AND QUIDEL BY TOPCO

Introduction

The following section of this joint proxy statement/prospectus explains, among other things, the effect of the Ortho Scheme and, together with the further information contained elsewhere in this joint proxy statement/prospectus, constitutes the explanatory statement in respect of the Ortho Scheme as required by section 897 of the UK Companies Act. Accordingly, in addition to the information contained in the following section of this joint proxy statement/prospectus, your attention is drawn to the further information contained elsewhere in this joint proxy statement/prospectus and you are advised to read this joint proxy statement/prospectus in full.

On December 22, 2021, it was announced that Ortho entered into the BCA with Quidel, Topco, U.S. Merger Sub, U.S. Holdco Sub and U.S. Holdco Sub 2, pursuant to which, among other things, the entire issued and to be issued share capital of Ortho will be transferred to GTU Ops Inc. (a Computershare entity) or another company mutually acceptable to Quidel and Ortho and falling within Section 67(6) of the Finance Act 1986 (the “DR Nominee”) (or, if the DR Nominee holds the Ortho Shares today, transferred within the DR Nominee) on behalf of Topco in exchange for the aggregate transaction deliverables (the “Ortho Combination”) by means of a court-sanctioned scheme of arrangement under Part 26 of the UK Companies Act.

Your attention is drawn to the section entitled “The Combinations” of this joint proxy statement/prospectus, which contains, among other things, (i) information on the reasons for and expected benefits of the Combinations and (ii) the unanimous recommendation by the Ortho board of directors to Ortho shareholders to vote in favor of the resolutions to be proposed at the Ortho Court Meeting and the Ortho General Meeting. The Ortho Scheme is set out in full in the section entitled “The Ortho Scheme” of this joint proxy statement/prospectus.

The Ortho Combination

The Ortho Combination is to be effected by means of the Ortho Scheme, a UK court-sanctioned scheme of arrangement between Ortho and the holders of Ortho Shares (i) in issue at the date of this document, (ii) issued after the date of this joint proxy statement/prospectus and prior to the Voting Record Time (if any), and (iii) issued at or after the Voting Record Time and prior to the Scheme Record Time (if any), either on terms that the original or any subsequent holders thereof shall be bound by or in respect of which the holders thereof shall have agreed in writing to be bound, by in each case, remaining in issue at the Scheme Record Time but excluding any Excluded Ortho Shares (as defined herein) and whose names appear in the register of members of Ortho at the Scheme Record Time (“Scheme Shares” and the holders thereof, “Scheme Shareholders”), under Part 26 of the UK Companies Act. Implementation of the Ortho Combination requires (i) the approval of the Ortho Scheme by the Ortho shareholders at the Ortho Court Meeting (the “Scheme Proposal”) and (ii) the approval of the proposal to (a) authorize the Ortho board of directors to take all action necessary or appropriate for carrying the Ortho Scheme into effect and (b) adopt the Ortho Articles in substitution for, and to the exclusion of, Ortho’s existing articles of association in order to facilitate the Combinations by the Ortho shareholders at the Ortho General Meeting (the “Scheme Implementation Proposal”). The Ortho Scheme also requires the sanction of the Court. The Ortho Scheme is set out in full in the section entitled “The Ortho Scheme” of this joint proxy statement/prospectus.

The purpose of the Ortho Scheme is to enable the DR Nominee, on Topco’s behalf, to acquire (or transfer within, as the case may be) the entire issued and to be issued share capital of Ortho. This is to be achieved by the DR Nominee, on Topco’s behalf, acquiring (or transferring within itself) the Ortho Shares held by the Scheme Shareholders at [●] [a.m./ p.m.] (Eastern Standard Time) and [6:00] p.m. (London time) on the Business Day immediately prior to the Ortho Effective Date (“Scheme Record Time”), in return for which the Scheme Shareholders will receive the cash consideration and the share deliverable for their Scheme Shares on the basis set out in the Ortho Scheme.

94

If the Ortho Combination is completed:

| • |  | all Ortho Shares will be acquired by (or held within, as the case may be) the DR Nominee, on Topco’s behalf; and

| • |  | holders of Ortho Shares as of the Scheme Record Time will, on the terms set out in the Ortho Scheme, have the right to receive for each Ortho Share held by them at such time the scheme deliverables, consisting of an amount equal to $7.14 in cash plus 0.1055 shares of common stock, par value $0.001 per share, of Topco.

Topco Shares shall be admitted to trading on Nasdaq under the trading symbol “[●]” no later than the time at which the Ortho Scheme shall be delivered to the Registrar and become effective. The Ortho Scheme consideration of 0.1055 Topco Shares and $7.14 in cash per Ortho Share had an implied value of $24.75 per Ortho Share based upon the closing price of Quidel Shares on December 21, 2021. Please refer to the opinions of Perella Weinberg and J. P. Morgan in the sections entitled “The Combinations—Opinion of Perella Weinberg Partners LP as Financial Advisor to Quidel” and “The Combinations—Opinion of J.P. Morgan Securities LLC as Financial Advisor to Ortho,” for further details of how such implied value was calculated and analysed.

No fractional Topco Shares will be issued pursuant to the Ortho Scheme to any holder of Ortho Shares. Each holder of Ortho Shares whom would otherwise have been entitled to receive a fraction of a Topco Share shall receive from the Exchange Agent, in lieu thereof, cash (without interest) in an amount representing such holder’s proportionate interest in the net proceeds from the sale (after deduction of the expenses of the sale, including commissions, taxes and out-of-pocket transaction costs of the Exchange Agent) by the Exchange Agent on behalf of all such holders of Topco Shares which would otherwise be issued (the “Excess Topco Shares”). The sale of the Excess Topco Shares by the Exchange Agent shall be executed on Nasdaq, and shall be executed in round lots to the extent practicable. Until the net proceeds of such sale or sales have been distributed to such former holders of Ortho Shares, the Exchange Agent shall hold such proceeds in trust for such holders (the “Fractional Interests Trust”). Topco shall pay all commissions, transfer taxes and other out-of-pocket transaction costs incurred in connection with such sale of the Excess Topco Shares. The Exchange Agent shall determine the portion of the Fractional Interests Trust to which each holder of Ortho Shares shall be entitled, if any, by multiplying the amount of the aggregate net proceeds comprising the Fractional Interests Trust by a fraction, the numerator of which is the amount of fractional Topco Shares to which such former holder of Ortho Shares is entitled and the denominator of which is the aggregate amount of fractional Topco Shares to which all holders of Ortho Shares are entitled. As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of Ortho Shares in lieu of fractional Topco Shares, the Exchange Agent shall make available such amounts to such former holders of Ortho Shares, without interest and subject to any required tax withholding. Any such sale shall be made within ten Business Days or such shorter period as may be required by applicable law as soon as reasonably practicable after the Ortho Effective Time.

Prior to the Ortho Court Meeting, Quidel will irrevocably commit to Topco and, as may be required, the Court (on terms satisfactory to each of them) to make available to Topco the cash consideration due pursuant to the Ortho Scheme, such that Quidel shall deposit, or cause to be deposited, in each case on behalf of Topco, with the Exchange Agent, for the benefit of Scheme Shareholders, for exchange through the Exchange Agent, sufficient cash to make delivery of the cash consideration pursuant to the Ortho Scheme (the “Cash Portion”).

Conditions to Complete the Combinations

The respective obligations of Ortho, Quidel, Topco, U.S. Merger Sub, U.S. Holdco Sub and U.S. Holdco Sub 2 to complete the Combinations are subject to the satisfaction (or, to the extent permitted by applicable law, waiver by such parties) of the following conditions:

95

| (v) | the absence of any applicable law enacted, entered, promulgated, adopted, enacted, issued or entered into by or with or enforced by any governmental authority or any United States or non-United States commission, board, agency or body that is not a governmental authority but is charged with the supervision or regulation of brokers, dealers, securities underwriting or trading, stock exchanges, commodities exchanges, electronic communication networks, insurance companies or agents, investment companies or investment advisers, including Nasdaq, that remains in effect and prohibits, restrains, prevents or makes illegal completion of the Combinations;

| (vi) | the Registration Statement of which this joint proxy statement/prospectus forms a part shall have been declared effective by the SEC under the Securities Act, and shall not be the subject of any stop order which is in effect suspending the effectiveness of the Registration Statement or any proceedings for that purpose;

| (vii) | Topco Shares to be delivered to Ortho shareholders and Quidel stockholders in connection with the Combinations being authorized for listing on Nasdaq, subject to official notice of issuance; and

| (viii) | any waiting period (and any extensions thereof) applicable to the Combinations and any agreement (including any timing agreement) with any governmental entity not to consummate the Combinations shall have, in each case, expired, been terminated, or been obtained, as applicable.

The obligation of Ortho and Topco to complete the Combinations is subject to the satisfaction (or, to the extent permitted by applicable law, waiver by Ortho) of the following additional conditions:

| (i) | Quidel having performed, in all material respects, all obligations required to be performed by Quidel at or prior to the closing of the Combinations;

| (ii) | the representations and warranties of Quidel being true and correct to the extent specified in the BCA;

| (iii) | no material adverse effect with respect to Quidel shall have occurred since December 22, 2021; and

| (iv) | the receipt of a certificate from an officer of Quidel confirming, on behalf of Quidel, the satisfaction of the conditions set forth in the immediately preceding three clauses.

The obligation of Quidel to complete the Combinations is subject to the satisfaction (or, to the extent permitted by applicable law, waiver by Quidel) of the following additional conditions:

| (i) | Ortho having performed, in all material respects, all of its obligations required to be performed by it at or prior to the closing of the Combinations;

| (ii) | the representations and warranties of Ortho being true and correct to the extent specified in the BCA;

| (iii) | no material adverse effect with respect to Ortho shall have occurred since December 22, 2021; and

| (iv) | the receipt of a certificate from an officer of Ortho confirming the satisfaction of the conditions set forth in the immediately preceding three clauses.

The Ortho Scheme can only become effective if all conditions to the Combinations, including the required Ortho shareholder approvals and the sanction of the Court, have been satisfied or (to the extent permitted by law) waived. The Ortho Scheme will become effective upon a copy of the Ortho Scheme Order being delivered to the Registrar. Subject to the satisfaction or waiver of the conditions to the Combinations, including the sanction of the Ortho Scheme by the Court, the Ortho Effective Time is expected to occur in the first half of 2022.

Shareholder Meetings

Before the Court’s sanction can be sought, the Ortho Scheme requires, among other things, approval of the Ortho Scheme terms and the Ortho Scheme by Scheme Shareholders at the Ortho Court Meeting. The Scheme Proposal must be approved by a simple majority in number of Ortho ordinary shareholders present and voting (and entitled to vote), either remotely (via the Virtual Meeting Platform) or by proxy, representing at least 75% in value of the Ortho Shares in respect of which a vote has been cast. Approval of the Scheme Proposal is required to consummate the Combinations. Ortho shareholders are also being asked to consider and approve the Scheme Implementation Proposal and the Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements (as defined below) at the Ortho General Meeting. If approved, the Scheme Implementation Proposal will (i) authorize the Ortho board of directors to take all action necessary or appropriate for carrying the Ortho Scheme into effect and (ii) adopt the Ortho Articles in substitution for, and to the exclusion of, Ortho’s existing articles of association in order to facilitate the Combinations. The Scheme Implementation Proposal will be

96

proposed as a special resolution at the Ortho General Meeting, which means that the Scheme Implementation Proposal must be approved by at least 75% of the votes cast by Ortho ordinary shareholders present and voting (and entitled to vote), either remotely (via the Virtual Meeting Platform) or by proxy at the Ortho General Meeting. Approval of the Scheme Implementation Proposal is required to consummate the Combinations.

The Dodd-Frank Act and Rule 14a-21(c) under the Exchange Act require that Ortho seek a non-binding, advisory vote from Ortho shareholders to approve the compensation that may be paid or become payable to Ortho’s named executive officers in connection with the Combinations and the agreements or understandings pursuant to which such compensation may be paid or become payable, as disclosed in the table entitled “Interests of Certain Persons in the Combinations (Ortho)—Golden Parachute Compensation” of this joint proxy statement/prospectus, including the associated narrative discussion (the “Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements”). The Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements will be proposed as an ordinary resolution at the Ortho General Meeting, which means that the Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements must be approved by a simple majority of the votes cast by Ortho ordinary shareholders present and voting (and entitled to vote), either remotely (via the Virtual Meeting Platform) or by proxy at the Ortho General Meeting. Unlike the Scheme Proposal and Scheme Implementation Proposal, the approval of the Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements is not required to consummate the Combinations.

Notices of both the Ortho Court Meeting and the Ortho General Meeting are set out at the beginning of this joint proxy statement/prospectus. Entitlement to attend and vote at these meetings and the number of votes which may be cast will be determined by reference to the register of members of Ortho at the Voting Record Time.

IF THE SCHEME OF ARRANGEMENT BECOMES EFFECTIVE, IT WILL BE BINDING ON ALL SCHEME SHAREHOLDERS, IRRESPECTIVE OF WHETHER OR NOT THEY ATTENDED OR VOTED AT THE ORTHO COURT MEETING OR THE GENERAL MEETING.

Date, Time, Place and Purpose of the Ortho Court Meeting

The Ortho Court Meeting will be held at [●], United States at [●] [a.m./ p.m.] (Eastern Standard Time) and [●] [a.m./ p.m.] (London time) on [●], 2022 for Scheme Shareholders on the register of members as at the Voting Record Time to consider and, if thought fit, approve the Ortho Scheme.

At the Ortho Court Meeting, voting will be by poll and each Scheme Shareholder present remotely (via the Virtual Meeting Platform) or by proxy will be entitled to one vote for each Ortho Share held as at the Voting Record Time. The approval required at the Ortho Court Meeting is a simple majority in number of the Ortho ordinary shareholders present and voting (and entitled to vote) remotely (via the Virtual Meeting Platform) or by proxy, representing at least 75% in value of the Ortho Shares in respect of which a vote has been cast.

YOU ARE STRONGLY URGED TO SIGN AND RETURN YOUR BLUE FORM OF PROXY FOR THE ORTHO COURT MEETING AS SOON AS POSSIBLE. THE COMPLETION AND RETURN OF THE FORMS OF PROXY WILL NOT PREVENT YOU FROM REMOTELY ATTENDING, SUBMITTING QUESTIONS AND VOTING AT EITHER THE ORTHO COURT MEETING OR THE ORTHO GENERAL MEETING, OR ANY ADJOURNMENT THEREOF, IN EACH CASE VIA THE VIRTUAL MEETING PLATFORM, IF YOU ARE ENTITLED TO AND WISH TO DO SO. HOLDERS OF THE BENEFICIAL INTERESTS IN ORTHO SHARES WILL BE ABLE TO SUBMIT WRITTEN QUESTIONS AND OBSERVE THE ORTHO COURT MEETING REMOTELY VIA THE VIRTUAL MEETING PLATFORM.

Date, Time, Place and Purpose of the Ortho General Meeting

The Ortho General Meeting will be held at [●], United States at [●] [a.m./ p.m.] (Eastern Standard Time) and [●] [a.m./ p.m.] (London time) on [●], 2022 for Ortho shareholders on the register of members as at the Voting Record Time to consider and, if thought fit, approve the Scheme Implementation Proposal as a special resolution and the Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements as an ordinary resolution.

At the Ortho General Meeting, voting on each of the Scheme Implementation Proposal and the Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements will be by poll and each Ortho shareholder present remotely (via

97

the Virtual Meeting Platform) or by proxy will be entitled to one vote for each Ortho ordinary share held as at the Voting Record Time. The approval required for the Scheme Implementation Proposal to be passed is at least 75% of the votes validly cast on such resolution remotely (via the Virtual Meeting Platform) or by proxy. The approval required for the Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements to be passed is a simple majority of the votes validly cast on such resolution remotely (via the Virtual Meeting Platform) or by proxy.

YOU ARE STRONGLY URGED TO SIGN AND RETURN YOUR WHITE FORM OF PROXY FOR THE GENERAL MEETING AS SOON AS POSSIBLE. THE COMPLETION AND RETURN OF THE FORMS OF PROXY WILL NOT PREVENT YOU FROM REMOTELY ATTENDING, SUBMITTING QUESTIONS AND VOTING AT EITHER THE ORTHO COURT MEETING OR THE GENERAL MEETING, OR ANY ADJOURNMENT THEREOF, IN EACH CASE VIA THE VIRTUAL MEETING PLATFORM, IF YOU ARE ENTITLED TO AND WISH TO DO SO. HOLDERS OF THE BENEFICIAL INTERESTS IN ORTHO ORDINARY SHARES WILL BE ABLE TO SUBMIT WRITTEN QUESTIONS AND OBSERVE THE ORTHO COURT MEETING REMOTELY VIA THE VIRTUAL MEETING PLATFORM.

Adoption of the Ortho Articles

Ortho Shares issued after the Scheme Record Time will not be subject to the Ortho Scheme. In order to ensure that the DR Nominee, on Topco’s behalf, acquires the entire issued and to be issued share capital of Ortho, it is therefore proposed that, pursuant to the Scheme Implementation Proposal, the Ortho Articles be adopted in substitution for, and to the exclusion of, Ortho’s existing articles of association and pursuant to the Ortho Articles, Ortho Shares issued after the Scheme Record Time (if any), other than to Topco or its nominees, will be automatically acquired by the DR Nominee, on behalf of Topco, subject to the same terms as under the Ortho Scheme.

It is also proposed that, pursuant to the Scheme Implementation Proposal, the Ortho Articles be adopted to ensure that any Ortho Shares issued at or after the Voting Record Time but prior to the Scheme Record Time will also be acquired as if they were Scheme Shares subject to the Ortho Scheme.

Promptly after the time at which the Ortho Scheme shall be delivered to the Registrar and become effective the Ortho Shares shall be de-listed from Nasdaq and the DR Nominee, on Topco’s behalf, shall be the sole shareholder in Ortho. The adoption of Ortho Articles shall reflect Ortho’s status as a sole shareholder company.

Advisory Approval of the Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements

It is proposed that, as an ordinary resolution to be proposed at the Ortho General Meeting, the Ortho shareholders vote on the approval (on a non-binding advisory basis) of the compensation that may be paid or become payable to Ortho’s named executive officers in connection with the Combinations and the agreements or understandings pursuant to which such compensation may be paid or become payable, as disclosed in the table entitled “Interests of Certain Persons in the Combinations (Ortho)—Golden Parachute Compensation” of this joint proxy statement/prospectus, including the associated narrative discussion. Failure to obtain this non-binding approval will not prevent the consummation of the Combinations.

Recommendation of the Ortho Board of Directors

The Ortho board of directors has unanimously approved the BCA and the actions required and contemplated therein, including the Combinations, and determined that such actions are advisable and in the best interests of Ortho and its shareholders. The Ortho board of directors unanimously recommends that Ortho shareholders vote “FOR” the Scheme Proposal at the Ortho Court Meeting, “FOR” the Scheme Implementation Proposal at the Ortho General Meeting and “FOR” the Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements at the Ortho General Meeting. See the section entitled “The Combinations—Ortho Reasons for the Combinations and Recommendation of the Ortho Board of Directors” of this joint proxy statement/prospectus for a more detailed discussion of the Ortho board of directors’ recommendation with respect to the Scheme Proposal, the Scheme Implementation Proposal and the Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements, including with respect to the opinion provided to Ortho by J. P. Morgan as more fully described below in the section “The Combinations—Opinion of J.P. Morgan Securities LLC as Financial Advisor to Ortho.”

98

Entitlement to Vote at the Ortho Shareholder Meetings

If you hold Ortho Shares registered in your own name as of the Voting Record Time, you are entitled to attend the Ortho Court Meeting and the Ortho General Meeting to vote either remotely or to appoint another person or persons as your proxy or proxies to attend and vote on your behalf, in accordance with the procedures further outlined in this joint proxy statement/prospectus. You are strongly encouraged to appoint the Chair of the Ortho Shareholder Meetings as your proxy. Only directors of Ortho will be permitted to attend in person. If any other person is appointed as proxy, he or she will not be permitted to attend the Ortho Shareholder Meetings in person, but will be able to attend, submit questions and vote at the Ortho Shareholder Meetings remotely via the Virtual Meeting Platform. Holders of the beneficial interests in Ortho Shares will be able to submit written questions and observe the Ortho Shareholder Meetings remotely via the Virtual Meeting Platform. Please see the section entitled “Explanatory Statement—Beneficial Holders” of this joint proxy statement/prospectus for further information in respect of such holdings and interests.

Holders of Ortho Shares who hold their Ortho Shares indirectly through a broker, bank, trust company or other nominee must rely on the procedures of such broker, bank, trust company or other nominee in order to assert the rights of a holder of Ortho Shares to vote at the Ortho Shareholder Meetings. If this applies to you, we encourage you to consult your broker, bank, trust company or other nominee as soon as possible.

If you are a beneficial holder but not the legal holder of Ortho Shares then, as a matter of English law, your name is not entered in Ortho’s register of members. Accordingly, if you wish to attend and vote directly (i.e., in your own name) at the Ortho Court Meeting or Ortho General Meeting in respect of all or part of your holding, you must become a registered holder of Ortho Shares by arranging for the completion of a stock transfer form by the applicable registered holder in respect of the Ortho Shares that you wish to be transferred into your name, pay any related UK stamp duty, if applicable, and send the completed stock transfer form and related documentation (as applicable) to Ortho’s transfer agent, Computershare Investor Services at Investor Services at 462 South 4th Street, Suite 1600, Louisville, KY, 40202, United States, prior to the Voting Record Time. Beneficial holders who wish to attend and vote directly at the Ortho Court Meeting or Ortho General Meeting should send such stock transfer form in respect of their Ortho Shares to permit processing to be completed by Computershare prior to the Voting Record Time.

If either Ortho Shareholder Meeting is adjourned, only those Ortho shareholders on the register of members at [●] [a.m./ p.m.] (Eastern Standard Time) and [6:00] [a.m./ p.m.] (London time) on the date which is two Business Days before the adjourned meeting will be entitled to attend and vote.

Quorum

The presence at the Ortho General Meeting of two qualifying persons entitled to vote on the business to be transacted at the Ortho General Meeting, present remotely (via the Virtual Meeting Platform) or by proxy, shall be a quorum. A “qualifying person” means (a) an individual who is a shareholder of Ortho, (b) a person authorized to act as the representative of a corporation in relation to the Ortho General Meeting or (c) a person appointed as a proxy of a shareholder in relation to the meeting.

The Ortho Directors and the Effect of the Ortho Scheme on their Interests

Details of the interests of Ortho directors in the share capital of Ortho and awards in respect of such share capital, are set out in the section entitled “Interests of Certain Persons in the Combinations (Ortho)” of this joint proxy statement/prospectus. Scheme Shares held by the Ortho directors at the Scheme Record Time will be subject to the Ortho Scheme.

In common with the other participants who hold Ortho Equity Rights, the Ortho directors who hold Ortho Equity Rights will be able to receive Ortho Shares to the extent that such awards vest and are exercised prior to the effective time.

It is proposed that, as an ordinary resolution to be proposed at the Ortho General Meeting, the Ortho shareholders vote on the approval (on a non-binding, advisory basis) of the compensation that may be paid or become payable to its named executive officers in connection with the Combinations and the agreements and understandings pursuant to which such compensation may be paid or become payable, as disclosed in the table entitled “Interests of Certain Persons in the Combinations (Ortho)—Golden Parachute Compensation” of this joint proxy statement/prospectus, including the associated narrative discussion.

99

Except as set out in the section entitled “Interests of Certain Persons in the Combinations (Ortho)” of this joint proxy statement/prospectus and the provisions of the BCA applicable to directors as described in the section entitled “The Business Combination Agreement” of this joint proxy statement/prospectus, the effect of the Ortho Scheme on the interests of Ortho directors does not differ from its effect on the interests of any other Ortho shareholder.

Sanction of the Ortho Scheme by the Court

Under the UK Companies Act, the Ortho Scheme also requires the sanction of the Court. The Court Sanction Hearing is currently expected to be held in the first half of 2022. Scheme Shareholders are entitled to remotely attend the Court Sanction Hearing, should they wish to do so, in person or through counsel.

Following sanction of the Ortho Scheme by the Court, the Ortho Scheme will become effective in accordance with its terms upon a copy of the Court Order being delivered to the Registrar.

Upon the Ortho Scheme becoming effective, it will be binding on all Scheme Shareholders holding Scheme Shares at the Scheme Record Time, irrespective of whether or not they attended or voted in favor of, or against, the Ortho Scheme at the Ortho Court Meeting or in favor of, or against, or withheld their vote on the Scheme Implementation Proposal at the Ortho General Meeting.

If the Ortho Scheme does not become effective by September 22, 2022 (or, if extended, January 22, 2023, as further described in the section entitled “The Business Combination Agreement—Termination” of this joint proxy statement/prospectus), the BCA may be terminated by either Quidel or Ortho, and the Ortho Scheme may not become effective.

Solicitation of Proxies

Ortho will bear its own costs and expenses incurred in connection with the filing, printing and mailing of this joint proxy statement/prospectus to Ortho shareholders and the retention of any information agent or other service provider in connection with the Combinations. This proxy solicitation is being made by Ortho on behalf of the Ortho board of directors. Ortho has hired MacKenzie Partners, Inc. to assist in the solicitation of proxies at an estimated total cost to Ortho of approximately in the range of $75,000 to $125,000, plus reimbursement of reasonable additional costs and out-of-pocket expenses. In addition to this mailing, proxies may be solicited by directors, officers or employees of Ortho or its affiliates in person or by telephone or electronic transmission. None of the directors, officers or employees will be directly compensated for such services.

Listings, Dealings, Delisting and Settlement

Delisting of Ortho Shares

On the Closing Date, entitlements to Scheme Shares will be cancelled, and share certificates in respect of Scheme Shares held in certificated form will cease to be valid documents of title and should be destroyed or, at the request of Topco, delivered up to the DR Nominee, or to any person appointed by Topco to receive the same.

As a result of the consummation of the Combinations, Ortho will become a wholly owned subsidiary of Topco following Topco’s contribution of the depositary receipts in the Ortho Shares and deferred shares to U.S. Holdco Sub (and, at least two days following such contribution, further transfer such depositary interests and deferred shares to U.S. Holdco Sub 2) and it is intended that Ortho will be re-registered as a private limited company under the applicable provisions of the UK Companies Act.

It is intended that the last day for dealings in Ortho Shares on Nasdaq will be the last Business Day before the effective time or the day of the Ortho Effective Time. It is intended that, prior to the Ortho Effective Time, applications be made to delist the Ortho Shares from Nasdaq and terminate the registration of the Ortho Shares under the Exchange Act to take effect promptly following the Ortho Effective Time.

Listing and Dealings in Topco Shares

The Topco Shares to be delivered pursuant to the Ortho Scheme will be delivered credited as fully paid and non-assessable. The Topco Shares will rank pari passu in all respects with the Topco Shares in issue on the Effective Date, including the right to receive and retain dividends or other distributions on the common stock of Topco declared, made or paid after the closing date.

100

As of the Closing Date, the Topco Shares will be listed on Nasdaq, and are not expected to be listed on any other securities exchange.

Settlement

Subject to the Ortho Scheme becoming effective, settlement of the scheme deliverables to which any Ortho shareholder is entitled under the Ortho Scheme will be effected in accordance with paragraph 5 of the Ortho Scheme which is set out in full in the section entitled “The Ortho Scheme” of this joint proxy statement/prospectus, as summarized below.

Settlement of Cash Consideration

Settlement of the cash consideration due pursuant to the Ortho Scheme (as well as any cash entitlement in respect of fractional shares) will be effected by cheque. All cheques will be in U.S. dollars. Payments made by cheque will be payable to the Scheme Shareholder(s) concerned. Cheques will be despatched by mail (or by international post or airmail, if outside the United States) to the address appearing on Ortho’s share register at the Scheme Record Time (or, in the case of joint holders, to the address of that joint holder whose name stands first in the said register in respect of such joint holding). If Ortho shareholders would like to receive payments in cash (by way of wire transfer), please contact the Exchange Agent at [●] and complete and submit the form which will be provided in accordance with the instructions thereon on or before the date falling [5] Business Days prior to the Court Sanction Hearing. Please note there will be a $[100] fee which will be deducted at the Ortho shareholder’s expense for each wire transfer.

All cheques shall be despatched and, in respect of Ortho shareholders who have requested that the cash consideration to which they are entitled is paid in cash, all wire transfers shall be instructed for settlement, on or as soon as reasonably practicable following the Ortho Scheme becoming effective.

Settlement of Share Consideration

Topco shall issue to each Scheme Shareholder the number of Topco Shares to which such Scheme Shareholder is entitled under the Ortho Scheme, and shall credit, or cause to be credited through the facilities of the Exchange Agent, such Topco Shares in book-entry form to the respective account of such Scheme Shareholder on the Exchange Agent’s records or the participants in DTC’s electronic book-entry clearing and settlement system, as soon as reasonably practicable following the Effective Date (and in any event no later than two Business Days following the Effective Date).

Fractions of Topco Shares will not be allotted to Scheme Shareholders. Instead, Scheme Shareholders shall receive, in lieu of such fractional entitlements, cash in an amount in U.S. dollars (rounded down to the nearest cent) equal to such fractional amount multiplied by the aggregate net proceeds from the sale of such fractional entitlements.

The number of Topco Shares to which each Scheme Shareholder is entitled under the Scheme shall be subject to adjustment for any share split, consolidation or other action impacting the number of Topco Shares to be received under the Ortho Scheme.

General

All documents and remittances sent to, from or on behalf of Ortho shareholders will be sent entirely at their own risk.

Beneficial Holders

As at the date of this joint proxy statement/prospectus, Ortho has two registered holders of Ortho Shares, being GTU Ops Inc., in respect of Computershare, and Cede & Co., in respect of The Depository Trust Company, (together the “Registered Holders”) who hold the relevant Ortho Shares in their names ultimately on behalf of the beneficial holders of such Ortho Shares (the “Beneficial Holders”). The information set forth in this section is of importance to Beneficial Holders, as the Scheme Shares (in respect of the Ortho Court Meeting) and Ortho Shares (in respect of the Ortho General Meeting) are held by the Registered Holders on behalf of the Beneficial Holders. As at the date of this joint proxy statement/prospectus, the Scheme Shareholders (in respect of the Ortho Court Meeting) and Ortho Shareholders (in respect of the Ortho General Meeting) are GTU Ops Inc. and Cede & Co. although this position might change at the time of the relevant Ortho Shareholder Meetings if a Beneficial Holder takes their Ortho Shares out of depositary arrangements and into their own name as described further in this joint proxy statement/prospectus and below.

101

Beneficial Holders (being holders of a book entry, beneficial or otherwise controlling voting and economic interest in an Ortho Share, the legal ownership of which is held on their behalf by a Registered Holder, and whose names do not therefore appear in the register of members of Ortho) will not be entitled to attend, speak at, vote at or otherwise participate in either the Ortho Court Meeting or the Ortho General Meeting (whether in person or remotely via the Virtual Meeting Platform, save in respect of an ability to submit questions and observe via the Virtual Meeting Platform as described in this joint proxy statement/prospectus and in the Virtual Meeting Guide prepared by Lumi).

Beneficial Holders as of [●] [a.m./ p.m.] (Eastern Standard Time) and [•] p.m. (London time) on [•] 2022 (the “Beneficial Holder Record Time”) will be entitled to instruct their brokers, investment firms, clearing houses and similar entities that own securities on behalf of the Beneficial Holders (the “Intermediaries”) how to vote the Scheme Shares and Ortho Shares in which they have a beneficial interest by completing and signing the materials provided to them in accordance with the instructions provided to them by their Intermediary.

Beneficial Holders should note that only proxies deposited by Scheme Shareholders and Ortho Shareholders (that is, individuals or entities whose names appear on the register of members of Ortho maintained by Computershare, acting as Ortho’s registrar, as registered holders of Scheme Shares and Ortho Shares) will be recognised and acted upon at the Ortho Court Meeting and the Ortho General Meeting. If Scheme Shares or Ortho Shares are listed in an account statement provided to a Beneficial Holder by an Intermediary, those Scheme Shares or Ortho Shares will, in all likelihood, be registered in the name of the Intermediary (or its agent). As at the date of this joint proxy statement/prospectus all such Scheme Shares and Ortho Shares are registered under the name of the Registered Holders.

The notice of the Ortho Court Meeting and Ortho General Meeting, the blue and white forms of proxy, the Virtual Meeting Guide and any other instructions as to voting from the Intermediaries (collectively, the “Meeting Materials”) will be sent to each Beneficial Holder by or on behalf of the Intermediary that holds Scheme Shares or Ortho Shares on their behalf. Intermediaries will typically use a service company to forward the Meeting Materials. The majority of Intermediaries now delegate responsibility for obtaining shareholder instructions from clients to [●]. [●] typically mails a Voting Instruction Form in lieu of the Form of Proxy. BENEFICIAL HOLDERS ARE REQUESTED TO VOTE IN ACCORDANCE WITH THE INSTRUCTIONS SET FORTH IN THE VOTING INSTRUCTION FORMS PROVIDED TO THEM BY THEIR INTERMEDIARIES. [●] will provide aggregate Scheme Shareholder and Ortho Shareholder voting instructions to the relevant Intermediary (or its tabulation agent), which will tabulate the results for the Ortho Court Meeting and the Ortho General Meeting and provide appropriate instructions with respect to the voting of the Scheme Shares and Ortho Shares to be represented at the Ortho Court Meeting and the Ortho General Meeting or the reconvening of any adjournment or postponement thereof.

Applicable securities regulatory policy requires Intermediaries, on receipt of materials that seek voting instructions from Beneficial Holders indirectly, to seek voting instructions from Beneficial Holders in advance of meetings of security holders. Every Intermediary has its own mailing procedures and provides its own return instructions, which should be carefully followed by Beneficial Holders in order to ensure that their wishes are expressed at the Ortho Court Meeting and the Ortho General Meeting or the reconvening or any adjournment or postponement thereof. Often, the form of proxy supplied to a Beneficial Holder by its broker is identical to the form of proxy provided to Scheme Shareholders and Ortho Shareholders; however, its purpose is limited to instructing the relevant Scheme Shareholder and Ortho Shareholder that is an Intermediary on how to vote on behalf of the Beneficial Holder. In the ordinary course, Beneficial Holders’ securities can only be voted by their Intermediaries in accordance with the Beneficial Holders’ instructions. Beneficial Holders should carefully follow the instructions provided by their Intermediaries in order to ensure that their wishes in respect of the Scheme Shares and Ortho Shares that they control are reflected at the Ortho Court Meeting and Ortho General Meeting or the reconvening of or any adjournment or postponement thereof.

Beneficial Holders will not be entitled to attend, speak at, vote at or otherwise participate in either the Ortho Court Meeting or the Ortho General Meeting (whether in person or remotely via the Virtual Meeting Platform).

Beneficial Holders as of the Beneficial Holder Record Time will however be entitled to instruct their broker or other Intermediary how to vote the Scheme Shares and Ortho Shares in which they have a beneficial interest by completing and signing the materials provided to them in accordance with the instructions provided to them by their broker or other Intermediary.

Beneficial Holders will also be able to submit questions ahead of and observe (but not participate in) the Ortho Court Meeting and the Ortho General Meeting remotely via the Virtual Meeting Platform, as described in this joint proxy statement/prospectus and the Virtual Meeting Guide prepared by Lumi.

102

Beneficial Holders are entitled to switch from being a Beneficial Holder to a Scheme Shareholder and/or Ortho Shareholder (so that the Scheme Shares and/or Ortho Shares previously held by the relevant Intermediary will be held directly by them).

Overseas Ortho Shareholders

The availability of the Ortho Scheme and the transaction deliverables to Ortho shareholders in a jurisdiction outside the United States may be affected by the laws of the relevant jurisdictions. Such overseas Ortho shareholders should inform themselves about, and should observe, any applicable legal requirements. It is the responsibility of all overseas Ortho shareholders to satisfy themselves as to their full compliance with the laws of the relevant jurisdiction, including obtaining any governmental, exchange control or other consents which may be required and their compliance with any other necessary formalities which are required to be observed and the payment of any issue, transfer or other taxes due in such jurisdiction. If you are in any doubt regarding such matters, you should consult an independent professional adviser in the relevant jurisdiction without delay.

Overseas Ortho shareholders should consult their own legal and tax advisers with respect to the legal and tax consequences of the Combinations in their particular circumstances.

Action to be Taken

The approval required for the Scheme Proposal at the Ortho Court Meeting is a simple majority in number of the Ortho ordinary shareholders present and voting (and entitled to vote) remotely (via the Virtual Meeting Platform) or by proxy, representing at least 75% in value of the Ortho Shares in respect of which a vote has been cast.

The approval required for the Scheme Implementation Proposal at the Ortho General Meeting is approval by at least 75% of the votes cast by Ortho ordinary shareholders present and voting (and entitled to vote), either remotely (via the Virtual Meeting Platform) or by proxy.

The approval required for the Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements at the Ortho General Meeting is approval by a simple majority of the votes cast by Ortho ordinary shareholders present and voting (and entitled to vote), either remotely (via the Virtual Meeting Platform) or by proxy.

IF THE SCHEME OF ARRANGEMENT BECOMES EFFECTIVE IT WILL BE BINDING ON ALL HOLDERS OF SCHEME SHARES IRRESPECTIVE OF WHETHER OR NOT THEY ATTENDED OR VOTED AT THE ORTHO COURT MEETING OR THE ORTHO GENERAL MEETING.

Forms of Proxy

Each copy of this joint proxy statement/prospectus mailed to holders of Ortho Shares is accompanied by two forms of proxy with instructions for voting. The blue form of proxy corresponds to the Ortho Court Meeting and the white form of proxy corresponds to the Ortho General Meeting. If you hold Ortho Shares in your name as a shareholder of record, you should complete and return both proxy cards accompanying this joint proxy statement/prospectus to ensure that your vote is counted at both of the Ortho Shareholder Meetings, or at any adjournment or postponement of the Ortho Shareholder Meetings, regardless of whether you plan to attend the Ortho Shareholder Meetings, so as to arrive as soon as possible but in any event at least 48 hours before the relevant meeting (excluding any part of such 48-hour period falling on a weekend or public holiday in the UK). You may also authorize a proxy to vote your shares online or electronically as set out in full on the proxy cards.

If the blue form of proxy relating to the Ortho Court Meeting is not lodged by the relevant time, it may be emailed to [●] or handed to the Chair at any time up to the Ortho Court Meeting, otherwise it will be invalid. In the case of the Ortho General Meeting, if the white form of proxy is not lodged so as to be received by the time mentioned above, it may be emailed to [●] or handed to the Chair at any time up to the Ortho General Meeting, otherwise it will be invalid. The completion and return of either form of proxy will not preclude you from attending the Ortho Court Meeting or the Ortho General Meeting and voting remotely (via the Virtual Meeting Platform), if you so wish.

If you hold your Ortho Shares in “street name” through a broker, bank, trust company or other nominee, you must direct your broker, bank, trust company or other nominee to vote in accordance with the instructions you have received from your broker, bank, trust company or other nominee.

103

The Ortho board of directors is not currently aware of any business to be acted upon at the Ortho Shareholder Meetings other than the matters described in this joint proxy statement/prospectus. If, however, other matters are properly brought before the Ortho Shareholder Meetings, the persons appointed as proxies will have discretion to vote or act on those matters as in their judgment is in the best interest of Ortho and its shareholders, except that Ortho will comply with any limitations on the exercise of such discretion under applicable law and stock exchange listing rules. The latest date by which Ortho is required to hold its annual general meeting is June 16, 2022 and such meeting shall not take place if the proposed Combinations have closed prior to this date.

The latest time for [Computershare] to receive your [Form of Proxy] will be [●] [a.m./ p.m.] (Eastern Standard Time) and [a.m./ p.m.] (London time) on [●], 2022 (or, in the case of an adjournment of the Ortho Court Meeting, 48 hours (excluding any part of such 48 hour period falling on a non-working day) before the time appointed for the adjourned meeting), being the latest time for receipt by Ortho’s Registrar of the blue form of proxy for the Ortho Court Meeting. You should allow sufficient time for posting for your [Form of Proxy] to be received. If the appointment is not received by [Computershare], Ortho’s registrar, by the relevant time, it may be emailed to [●] or handed to the Chair at any time prior to the commencement of the Ortho Court Meeting otherwise it will be invalid.

Further details on how to submit your Form of Proxy are set forth in the section entitled “[•]” of this joint proxy statement/prospectus.

YOU ARE STRONGLY URGED TO COMPLETE AND RETURN YOUR FORMS OF PROXY AS SOON AS POSSIBLE, WHETHER OR NOT YOU INTEND TO ATTEND THE SHAREHOLDER MEETINGS VIA THE VIRTUAL MEETING PLATFORM.

A summary of material tax considerations are set out in the sections entitled “Material U.S. Federal Income Tax Considerations” and “Material UK Tax Considerations” of this joint proxy statement/prospectus.

104

THE ORTHO GENERAL MEETING

Ortho Proposal No. 1—Scheme Implementation Proposal

For the reasons described above, Ortho is requesting that the Ortho shareholders adopt the following resolution at the Ortho General Meeting, which is a special resolution:

THAT, for the purpose of giving effect to the scheme of arrangement dated [•], 2022 between Ortho Clinical Diagnostics Holdings plc (“Ortho”) and the holders of Scheme Shares (as defined in such scheme of arrangement), a print of which has been produced to this meeting and for the purposes of identification signed by the Chair of this meeting, in its original form or with or subject to any modification, addition, or condition as may be agreed from time to time (including, for the avoidance of doubt, after the date of this resolution) between Ortho, Quidel Corporation, a Delaware corporation (“Quidel”), Coronado Topco, Inc. a Delaware corporation and wholly owned subsidiary of Ortho (“Topco”), Laguna Merger Sub, Inc. a Delaware corporation and wholly owned subsidiary of Topco, (“U.S. Merger Sub”), Orca Holdco, Inc., a Delaware corporation and a wholly owned subsidiary of Topco (“U.S. Holdco Sub”), Orca Holdco 2, Inc., a Delaware corporation and wholly owned subsidiary of U.S. Holdco Sub (“U.S. Holdco Sub 2”), and which (if required) is approved by the High Court of Justice of England and Wales (the “Court”), or which is otherwise imposed by the Court and is mutually acceptable to Ortho, Quidel, U.S. Merger Sub, U.S. Holdco Sub and U.S. Holdco Sub 2 each acting reasonably and in good faith (the “Scheme”):

| (A) | the directors of Ortho (or a duly authorized committee of the directors) be and are hereby authorized to take all such action as they may consider necessary or appropriate for carrying the Scheme into effect; and

| (B) | with effect from the passing of this resolution, the articles of association of Ortho attached as Annex F and incorporated herein by reference be adopted as the articles of association of Ortho in substitution for, and to the exclusion of, Ortho’s existing articles of association

Vote Required and Ortho board of directors Recommendation

Assuming a quorum is present, the Scheme Implementation Proposal will be passed if at least 75% of the votes cast at the Ortho General Meeting (remotely via the Virtual Meeting Platform, or by proxy) are cast in favor of this proposal.

Completion of the Combinations is conditioned upon Ortho shareholder approval of the Scheme Implementation Proposal.

THE ORTHO BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE SCHEME IMPLEMENTATION

Ortho Proposal No. 2—Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements

In accordance with the Dodd-Frank Act and Section 14A of the Exchange Act, Ortho is providing Ortho shareholders with the opportunity to cast a non-binding advisory vote on the compensation that may be paid or become payable to the Ortho’s named executive officers in connection with the Combinations. As required by those rules, Ortho is asking Ortho shareholders to vote on the approval of the following resolution, which is an ordinary resolution:

“THAT, the compensation that may be paid or become payable to Ortho’s named executive officers in connection with the Combinations, as disclosed in the table entitled “Interests of Certain Persons in the Combinations (Ortho)—Golden Parachute Compensation” in this joint proxy statement/prospectus, including the associated narrative discussion, and the agreements or understandings pursuant to which such compensation may be paid or become payable, are hereby approved.”

The vote on this proposal is a vote separate and apart from the Scheme Implementation Proposal. Accordingly, you may vote in favor of the Scheme Implementation Proposal and vote not to approve this proposal and vice versa. Because this proposal is only advisory in nature, it will not be binding on Ortho or the Ortho board of directors.

Accordingly, because Ortho is contractually obligated to pay the compensation, such compensation will be paid or become payable, subject only to the conditions applicable thereto, if the Combinations are consummated and regardless of the outcome of the advisory proposal.

105

Assuming a quorum is present, the Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements will be passed if a simple majority of the votes cast at the Ortho General Meeting (remotely via the Virtual Meeting Platform, or by proxy) are cast in favor of this resolution.

THE ORTHO BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL OF THE NON-BINDING ADVISORY PROPOSAL TO APPROVE CERTAIN COMPENSATION ARRANGEMENTS.

TRANSACTION PROPOSED—YOUR VOTE IS VERY IMPORTANT

[●], 2022

Dear Fellow Shareholder:

As previously announced, on December 22, 2021, Ortho Clinical Diagnostics Holdings plc (“Ortho”) entered into a transaction agreement (as it may be amended, the “Transaction Agreement”) with Quidel Corporation, a Delaware corporation (“Quidel”), Coronado Topco, Inc. a Delaware corporation and wholly owned subsidiary of Ortho (“Topco”), Laguna Merger Sub, Inc. a Delaware corporation and wholly owned subsidiary of Topco, (“U.S. Merger Sub”), Orca Holdco, Inc., a Delaware corporation and a wholly owned subsidiary of Topco (“U.S. Holdco Sub”), Orca Holdco 2, Inc., a Delaware corporation and wholly owned subsidiary of U.S. Holdco Sub (“U.S. Holdco Sub 2”), pursuant to which the entire issued and to be issued share capital of Ortho will be transferred to the DR Nominee (as defined below) on behalf of Topco (the “Transaction”) by means of a court-sanctioned scheme of arrangement (the “Scheme of Arrangement”) under Part 26 of the UK Companies Act.

We cordially invite all holders of Ortho ordinary shares to attend two meetings of shareholders of Ortho. The first meeting (the “Court Meeting”) will be held at [●], [●] on [●], 2022 at [●] [a.m./ p.m.] (Eastern Standard Time) and [●] [a.m./ p.m.] (London time). The second meeting (the “General Meeting” and, together with the Court Meeting, the “Shareholder Meetings”) will be held at [●], United Kingdom on [●], 2022 at [●] [a.m./ p.m.] (Eastern Standard Time) and [●] [a.m./ p.m.] (London time) (or as soon thereafter as the Court Meeting shall have been concluded or adjourned).

At the Court Meeting, Ortho shareholders will be asked to consider and vote on the Scheme of Arrangement. At the General Meeting, Ortho shareholders will be asked to consider and vote on (1) a proposal (i) authorizing the Board of Directors of Ortho (the “Ortho Board”) to take all action necessary or appropriate for carrying the Scheme of Arrangement into effect and (ii) amending the articles of association of Ortho in order to facilitate the Transaction and (2) a non-binding advisory proposal to approve certain compensation arrangements for the named executive officers of Ortho.

Transaction Overview

If the Transaction is completed:

| • |  | all ordinary shares, par value $0.00001 per share, of Ortho (“Ortho ordinary shares”) will be transferred to GTU Ops Inc. (a Computershare entity) or another company mutually acceptable to Ortho and Quidel falling within Section 67(6) of the UK Finance Act 1986 that Topco appoints in order to act as transferee of the Ortho ordinary shares pursuant to the Scheme of Arrangement (the “DR Nominee”); and

| • |  | holders of Ortho ordinary shares as of the record time for the Scheme of Arrangement will, on the terms set out in the Scheme of Arrangement, have the right to receive for each Ortho ordinary share held by them at such time an amount equal to $7.14 in cash (the “cash consideration”) plus an amount of Topco ordinary shares, nominal value $0.001 per share (“Topco ordinary shares”), equal to 0.1055 Topco ordinary shares per Ortho ordinary share, subject to the provisions of paragraph 2.3 (“the exchange ratio”) (the “share deliverable” and, together with the cash consideration, the “scheme deliverables”).

Topco ordinary shares shall be admitted to trading on the Nasdaq Global Select Market under the trading symbol “[●]” no later than the time at which the Scheme of Arrangement shall be delivered to the Registrar of Companies in England and Wales and become effective.

107

COVID-19 Restrictions

At the time of mailing of this letter, the UK Government has removed restrictions on large public gatherings. However, in light of the ongoing restrictions in the United States and the uncertainty surrounding COVID-19 and the possible reintroduction by the UK Government of measures restricting large public gatherings, and in order to protect the health and safety of the Ortho shareholders and Ortho directors, officers and employees, Ortho shareholders will not be permitted to attend the Shareholder Meetings in person, except for the Chair of the Shareholder Meetings and anyone else nominated by the Chair of the Shareholder Meetings. However, holders of Ortho ordinary shares will be able to attend, submit written questions and vote at each Shareholder Meeting remotely via the Virtual Meeting Platform (as defined in the notices that follow), further details of which are set out in the accompanying joint proxy statement/prospectus. We would, however, nonetheless encourage all Ortho ordinary shareholders to vote by proxy as soon as possible, by returning the accompanying forms of proxy, even if they intend to attend the Shareholder Meetings remotely via the Virtual Meeting Platform. Holders of the beneficial interests in Ortho ordinary shares will be able to submit written questions and observe each Shareholder Meeting remotely via the Virtual Meeting Platform. Please see the section entitled “Explanatory Statement—Beneficial Holders” of this joint proxy statement/prospectus for further information in respect of such holdings and interests.

Voting

It is important that holders of Ortho ordinary shares vote at both of the Shareholder Meetings.

Holders of Ortho ordinary shares are encouraged to submit a form of proxy (by post, online or electronically through MacKenzie Partners, Inc.) for each of the Court Meeting and the General Meeting as soon as possible. Holders of Ortho ordinary shares who hold their Ortho ordinary shares indirectly through a broker, bank, trust company or other nominee must rely on the procedures of such broker, bank, trust company or other nominee in order to assert the rights of a holder of Ortho ordinary shares to vote at the Shareholder Meetings. If this applies to you, we encourage you to consult your broker, bank, trust company or other nominee as soon as possible.

For specific instructions on voting Ortho ordinary shares, please refer to the accompanying joint proxy statement/prospectus and forms of proxy.

Recommendation of the Ortho Board

The Ortho Board considers, having been so advised by its financial advisor J.P. Morgan Securities LLC, financial advisor to Ortho in connection with the Transaction, as to financial terms of the Transaction, the terms of the Transaction to be in the best interests of Ortho and its shareholders taken as a whole. Accordingly, the Ortho Board unanimously recommends that Ortho shareholders vote:

| • |  | “FOR” the approval of the Scheme of Arrangement at the Court Meeting; and

| • |  | “FOR” the approval of each of the resolutions at the General Meeting.

The Ortho Board made its determination after evaluating the Transaction in consultation with Ortho’s management and legal and financial advisors, and after considering a number of factors.

In considering the recommendation of the Ortho Board, you should be aware that directors and executive officers of Ortho may have certain interests in the Transaction that may be different from, or in addition to, the interests of Ortho shareholders generally. See the sections entitled “The Ortho General Meeting—Proposal No. 2 —Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements” and “Interests of Certain Persons in the Combinations (Ortho)” of the accompanying joint proxy statement/prospectus for further information regarding these interests.

We urge you to read the accompanying joint proxy statement/prospectus, including any documents incorporated by reference therein and the annexes thereto, carefully and in their entirety. In particular, we urge you to read carefully the section entitled “Risk Factors” in the accompanying joint proxy statement/prospectus for risks relating to the Transaction and Topco following the Transaction.

If you have any questions regarding the accompanying joint proxy statement/prospectus, including any questions on how to vote please contact Ortho’s registrar, Computershare, or Ortho’s proxy solicitor, MacKenzie Partners, Inc., at the contact information below. Please note that neither Computershare (Ortho’s registrar) nor MacKenzie Partners, Inc. (Ortho’s proxy solicitor) can provide advice on the merits of the Combinations or the Scheme or give any financial, legal or tax advice.

The Scheme

1. | Transfer of the Scheme Shares

1.2 | The Scheme Shares shall be transferred to the DR Nominee (or, if the DR Nominee holds the Scheme Shares at the Effective Time, transferred within the DR Nominee), on behalf and for the benefit of Topco, and to give effect to such transfer, any person may be appointed by Topco as attorney or agent and shall be authorized as such attorney or agent on behalf of each of the Scheme Shareholders concerned to execute and deliver as transferor such form(s) of transfer or other instrument(s) or instruction(s) giving effect to such transfer of, or otherwise give any instruction(s) giving effect to such transfer, the Scheme Shares and every form, instrument or instruction so executed or instruction so given shall be as effective as if it had been executed or given by the holder or holders of the Scheme Shares thereby transferred. Any such form of transfer or other instrument or instruction shall be deemed to be the principal instrument of transfer of the relevant Scheme Shares and the equitable or beneficial interest in the Scheme Shares shall only be transferred together with the legal interest in such Scheme Shares, pursuant to such form, instruction or instrument of transfer.

1.3 | From the Effective Time and pending the transfer of the Scheme Shares pursuant to paragraphs 1.1 and 1.2, each Scheme Shareholder:

| (A) | irrevocably appoints Topco (and/or its nominee(s) and/or each of their agents and directors) as its attorney and/or agent:

113

| (ii) | to sign on behalf of such Scheme Shareholder such documents, and to do such things, as may, in the opinion of Topco and/or its nominee(s) and/or each of their respective agents and directors (in each case acting reasonably), be necessary or desirable in connection with the exercise of any voting rights and any or all rights and privileges attaching to such Scheme Shares (including: (i) execute any consent to short notice of a general or separate class meeting; (ii) attend and/or execute a form of proxy or forms of proxy in respect of such Scheme Shares appointing any person nominated by Topco and/or its nominee(s) to attend general and separate class meetings of the Company; and (iii) exercise or refrain from exercising the votes attaching to the Scheme Shares held by such Scheme Shareholder on such Scheme Shareholders’ behalf);

| (B) | authorizes the Company and/or its agents to send to Topco and/or its nominee(s) any notice, circular, warrant or other document or communication which may be required to be sent to them as a Member; and

| (C) | agrees not to exercise any votes or any other rights attaching to the relevant Scheme Shares without the consent of Topco, and irrevocably undertakes not to appoint a proxy or representative for or to attend any general meeting or separate class meeting of the Company.

1.4 | The authorities granted by each Scheme Shareholder pursuant to paragraph 1.2 and paragraph 1.3 shall be treated for all purposes as having been granted by deed.

1.5 | The Company shall, subject to the UK stamping of any relevant instruments of transfer (to the extent required), register, or procure the registration of, any transfer(s) of shares effected in accordance with paragraphs 1.1 and 1.2.

2. | Consideration for the Transfer of the Scheme Shares

2.1 | On or before the Effective Time, Quidel shall deposit, or cause to be deposited, in each case on behalf of Topco, with the Exchange Agent, for the benefit of the holders of the Scheme Shares, an amount equal to the Cash Consideration and, subject to and in exchange for the transfer of the Scheme Shares as provided in paragraphs 1.1 and 1.2, as soon as reasonably practicable following the Effective Time, Topco shall, subject as hereinafter provided:

| (A) | in accordance with paragraph 5.1(A), pay, or procure that there shall be paid, a cash amount to, or for the account of, each Scheme Shareholder of $7.14 (seven U.S. dollars, 14 U.S. cents), without interest but subject to any adjustment in accordance with this Scheme and withholding tax required by Applicable Law, for each Scheme Share held by that Scheme Shareholder (the “Cash Consideration”); and

| (B) | in accordance with paragraph 5.1(B), issue to or for the account of each Scheme Shareholder, such number of Topco Shares as such Scheme Shareholder is entitled to receive pursuant to the application of the Exchange Ratio, subject to the provisions of paragraph 2.3 and any adjustment in accordance with this Scheme (the “Share Consideration”), credited as fully paid, non-assessable and free from all Liens (other than transfer restrictions arising under applicable securities laws), and such Topco Shares will rank pari passu in all respects with the Topco Shares in issue on the Effective Date, including the right to receive and retain dividends and other distributions declared, made or paid by reference to a record date falling on or after the Effective Date and to participate in the assets of Topco upon a winding up of Topco. Applications will be made for the Topco Shares to be listed on Nasdaq.

2.2 | If, between the date of the Transaction Agreement and the Effective Time, the outstanding Company Ordinary Shares or Topco Shares shall have been changed to, or exchanged for, a different number or class of shares or securities by reason of any stock dividend, bonus issue, scrip dividend, subdivision, reorganization, merger, consolidation, reclassification, redesignation, recapitalization, share split, reverse share split, combination or exchange of shares, or a stock or scrip dividend shall be declared with a record date within such period, or any similar event shall have occurred, then the amount of the Cash Consideration and/or Exchange Ratio shall be appropriately adjusted in accordance with the provisions of the Transaction Agreement to provide to Topco and the Scheme Shareholders the same economic effect as contemplated by the Transaction Agreement prior to such event.

2.3 | Fractions of Topco Shares will not be allotted to Scheme Shareholders. Instead, Scheme Shareholders shall receive within ten Business Days or such shorter period as may be required by Applicable Law as soon as reasonably practicable after the Effective Time, in lieu of such fractional entitlements, cash in an amount in U.S. dollars (rounded down to the nearest cent) equal to such fractional amount multiplied by the aggregate net proceeds from the sale of such fractional entitlements.

3. | Share Certificates and Register of Members

3.1 | With effect from and as of the Effective Time, all certificates representing Scheme Shares in certificated form, if any, shall cease to have effect as documents of title to the Scheme Shares comprised therein and each Scheme Shareholder

114

| shall be bound, at the request of Topco, to deliver up the same to the DR Nominee or to any person appointed by Topco to receive the same or, as Topco may direct, to destroy the same.

3.2 | On or as soon as reasonably practicable after the Effective Time and subject to the completion of such transfers, forms, instruments or instructions as may be required in accordance with paragraph 1 and the UK stamping thereof (to the extent required), the Company shall procure that appropriate entries shall be made in the register of Members of the Company to reflect the transfer of the Scheme Shares in accordance with paragraph 1.

4. | Appointment of Exchange Agent

Prior to the Effective Time, Topco shall appoint the Exchange Agent to effect the technical implementation of the settlement of the Cash Consideration, the delivery of the Exchange Shares to all Scheme Shareholders and the sale of, and distribution of proceeds from the sale of, fractions of Topco Shares sold pursuant to paragraph 2.4.

5. | Settlement of the Cash Consideration and the Share Consideration

5.1 | In the case of Scheme Shares held by Scheme Shareholders at the Scheme Record Time, settlement shall be effected as follows:

| (A) | settlement of the Cash Consideration to which the Scheme Shareholder is entitled (including pursuant to paragraph 2.4) shall be effected by Topco, either directly or indirectly via the Exchange Agent:

| (i) | by cheque; or

| (ii) | [by cash (to be made by way of wire transfer), if the Scheme Shareholder has contacted the Exchange Agent at [●] and completed and submitted the form provided in accordance with the instructions thereon on or before the date falling five Business Days prior to the Court Sanction Hearing],

in each case, which shall be dispatched (in the case of a cheque) or for settlement (in the case of a wire transfer) on or as soon as reasonably practicable following the Effective Date (and in any event no later than two Business Days following the Effective Date); and

| (B) | settlement of the Share Consideration to which the Scheme Shareholder is entitled shall be effected by:

| (i) | [where, immediately prior to the Scheme Record Time, a Scheme Shareholder holds their Scheme Shares in book-entry form through a DTC participant in DTC’s electronic book-entry clearing and settlement system, Topco shall procure that (1) the Topco Shares to which the holder of such Scheme Shares is entitled shall be issued to Cede & Co., which will be the registered holder of such shares, as nominee for DTC; (2) the interests in such Topco Shares shall be credited by DTC to the account of the DTC participant through which the Scheme Shareholder holds its Scheme Shares in book-entry form;] or

| (ii) | where, immediately prior to the Scheme Record Time, a Scheme Shareholder holds their Scheme Shares in certificated or book-entry form on the records of the Exchange Agent, Topco procuring that the relevant Topco Shares are issued by the Exchange Agent in book-entry form on the records of the Exchange Agent, registered in the same name(s) and address as appeared on Ortho’s register of members for each relevant Scheme Shareholder,

in each case, as soon as reasonably practicable following the Effective Date (and in any event no later than [2] Business Days following the Effective Date).

5.2 | All deliveries of notices, certificates and/or cheques required to be made under this Scheme shall be made by sending the same by mail (or by international post or airmail, if outside United States), addressed to the person entitled thereto, to the address appearing in the register of members or, in the case of joint holders, to the address of the holder whose name stands first in such register in respect of the joint holding concerned at such time.

5.3 | All cheques shall be in U.S. dollars and shall be made payable to the Scheme Shareholder concerned or, in the case of joint holders, to the holder whose name stands first in the register of members in respect of the joint holding concerned at the Scheme Record Time and the encashment of any such cheque or the making of any such wire transfer as is referred to in paragraph 5.1(A) shall be a complete discharge to Topco for the monies represented thereby.

115

5.4 | None of the Company, Topco or their respective agents or nominees shall be responsible for any loss or delay in the transmission of the share certificates or cheques (as applicable) sent to Scheme Shareholders in accordance with this paragraph 5, which shall be posted at the risk of the Scheme Shareholder concerned.

6. | Oversees Shareholders

6.1 | The provisions of paragraphs 2, 3, 4, and 5 shall be subject to any prohibition or condition imposed by Applicable Law. Without prejudice to the generality of the foregoing, if, in respect of any Scheme Shareholder with a registered address in a jurisdiction outside the United Kingdom or the United States, Topco or the Exchange Agent is advised that the delivery of Exchange Shares pursuant to paragraph 5 would or might infringe the laws of such jurisdiction or would require Topco, the Exchange Agent or the Company to observe any governmental or other consent or any registration, filing or other formality with which Topco, the Exchange Agent or the Company (as the case may be) is unable to comply, or compliance with which by such person is regarded by such person or by Topco (in the case of Topco, acting reasonably) as unduly onerous, the Exchange Agent may, in consultation with Topco, determine that the Exchange Shares shall not be delivered to such Scheme Shareholder and that (i) such Exchange Shares shall instead be sold by the Exchange Agent at the best price which can reasonably be obtained in the market at the time of sale and (ii) the net proceeds of such sale (after the deduction of any expenses and commissions incurred in connection with such sale, including any amounts in respect of tax including any value added tax payable thereon, without interest) shall be delivered by the Exchange Agent to the relevant Scheme Shareholder in accordance with the provisions of paragraphs 2.3, 5.1, 5.3 and 5.4 (as applicable) rounded up or down to the nearest U.S. cent.

6.2 | In the absence of bad faith or willful default, none of the Company, Topco, the Exchange Agent, the nominee or any broker or agent of any of them shall have any liability for any loss or damage arising as a result of the timing or terms of any sale pursuant to paragraph 6.1

7. | Cessation of Rights

With effect from and on the Effective Time, the Scheme Shareholders shall in accordance with this Scheme cease to have any rights with respect to the Scheme Shares, except the right to receive the Cash Considerations and the Share Consideration in exchange for the Scheme Shares as set out in paragraph 2.

Recommendation of the Quidel Board of Directors

After careful consideration, the Quidel board of directors has determined that the Combinations, including the Quidel Merger and the other transactions contemplated by the BCA, are consistent with and will further the business strategies and goals of Quidel, and are in the best interests of Quidel and its stockholders, and (a) has unanimously approved and declared advisable the BCA and Combinations, including the Quidel Merger and the transactions contemplated by the BCA, and (b) has determined, subject to its duties under applicable law, to recommend that the Quidel stockholders adopt the BCA and the Combinations.

Accordingly, the Quidel board of directors recommends that Quidel stockholders vote:

| 1. | “FOR” the Merger Proposal;

| 2. | “FOR” the Advisory Merger Compensation Proposal;

| 3. | “FOR” the Adjournment Proposal;

| 4. | “FOR” the Election of Directors Proposal;

117

| 5. | “FOR” the Advisory Executive Compensation Proposal;

| 6. | “FOR” the Independent Registered Public Accounting Firm Proposal;

| 7. | “FOR” the Equity Incentive Plan Proposal; and

| 8. | “FOR” the ESPP Proposal.

Record Date; Stockholders Entitled to Vote

The Quidel board of directors has fixed the close of business on March 14, 2022, as the record date for determining the Quidel stockholders entitled to receive notice of, and to vote at, the Quidel Stockholders’ Meeting. Only holders of record of issued and outstanding Quidel Shares at the close of business on the record date are entitled to receive notice of, and to vote at, the Quidel Stockholders’ Meeting.

At the close of business on March 14, 2022, there were [●] Quidel Shares issued and outstanding and entitled to vote at the Quidel Stockholders’ Meeting. Quidel stockholders are entitled to one vote for each Quidel Share they owned as of the close of business on the record date.

Voting by Quidel’s Directors and Executive Officers

At the close of business on March 4, 2022, directors and executive officers of Quidel and their affiliates were entitled to vote approximately 1,154,623 Quidel Shares, or approximately 2.7% of the Quidel Shares outstanding on that date. We currently expect that Quidel’s directors and executive officers will vote their shares in favor of each of the proposals to be considered at the Quidel Stockholders’ Meeting.

Quorum

A majority of the Quidel Shares issued and outstanding as of the close of business on the record date and entitled to vote, present in person or represented by proxy, at the Quidel Stockholders’ Meeting will constitute a quorum for the Quidel Stockholders’ Meeting. Abstentions and broker non-votes will be counted for purposes of establishing a quorum at the Quidel Stockholders’ Meeting. At any adjourned meeting at which a quorum is present, any business may be transacted that might have been transacted at the original meeting.

Required Vote

Approval of the Merger Proposal requires the affirmative vote of the holders of a majority of the outstanding Quidel Shares entitled to vote on the matter at the Quidel Stockholders’ Meeting.

Approval of each of (i) the Advisory Merger Compensation Proposal, (ii) the Adjournment Proposal, (iii) the Advisory Executive Compensation Proposal, (iv) the Independent Registered Public Accounting Firm Proposal, (v) the Equity Incentive Plan Proposal and (vi) the ESPP Proposal requires the affirmative vote of a majority of the voting power represented at the Quidel Stockholders’ Meeting in person or by proxy and entitled to vote on such proposals.

Approval of the Election of Directors Proposal requires the affirmative vote of a plurality of the voting power represented at the Quidel Stockholders’ Meeting in person or by proxy and entitled to vote on such proposal.

Failure to Either Submit a Proxy or Attend the Quidel Stockholders’ Meeting, Broker Non-Votes and Abstentions

Where a stockholder has directed how his or her proxy is to be voted, it will be voted according to the stockholder’s directions. If your shares are held in a brokerage account or by another nominee, you are considered the “beneficial owner” of shares held in “street name,” and this joint proxy statement/prospectus and the related materials are being forwarded to you by your broker or nominee (the “record holder”) along with a voting instruction card. As the beneficial owner, you have the right to direct the record holder of your shares regarding how to vote your shares, and the record holder is required to vote your shares in accordance with your instructions. If a proposal is routine, a record holder may vote on the proposal without voting instructions from the beneficial owner if the beneficial owner does not provide instructions. If a proposal is non-routine, the record holder may vote on the proposal only if the beneficial owner has provided voting instructions. A “broker non-vote” occurs when the record holder is unable to vote on a proposal because the proposal is non-routine and the beneficial owner does not provide instructions.

118

If you hold shares in street name and you do not give voting instructions to the record holder of your shares prior to the Quidel Stockholders’ Meeting, the record holder will be entitled to vote your shares in its discretion only on the Independent Registered Public Accounting Firm Proposal and will not be able to vote your shares on the rest of the proposals presented at the Quidel Stockholders’ Meeting and your shares will be treated as a “broker non-vote” on these proposals. If the Quidel Stockholders’ Meeting is adjourned, your shares may be voted by the persons named as proxies on the new meeting date as well, unless you have revoked your proxy instructions prior to that time.

With regard to the Merger Proposal, if you fail to submit a proxy or attend the Quidel Stockholders’ Meeting, fail to instruct your broker, bank, trust company or other nominee to vote (broker non-votes), or if you mark your proxy or voting instructions to abstain, it will have the effect of a vote “AGAINST” the Merger Proposal.

With regard to the Advisory Merger Compensation Proposal, the Adjournment Proposal, the Advisory Executive Compensation Proposal, the Equity Incentive Plan Proposal and the ESPP Proposal, if you fail to submit a proxy or attend the Quidel Stockholders’ Meeting or fail to instruct your broker, bank, trust company or other nominee to vote (broker non-votes), it will have no effect on these proposals; while if you mark your proxy or voting instructions to abstain, it will have the effect of a vote “AGAINST” these proposals.

With regard to the Election of Directors Proposal, votes may be cast in favor of a director nominee or withheld. Because directors are elected by plurality, broker non-votes will have no effect on the outcome of this proposal. If a quorum is present at the Quidel Stockholders’ Meeting, the eight nominees receiving the greatest number of votes will be elected.

With regard to the Independent Registered Public Accounting Firm Proposal, if you fail to submit a proxy or attend the Quidel Stockholders’ Meeting, it will have no effect on this proposal; while if you mark your proxy or voting instructions to abstain, it will have the effect of a vote “AGAINST” this proposal. Because the Independent Registered Public Accounting Firm Proposal is a routine matter, no broker non-votes are expected with respect to this proposal.

How to Vote Your Shares

Registered Quidel stockholders may grant a proxy to vote (i) through the Internet by logging onto the website indicated on the enclosed proxy card and following the prompts using the control number located on the proxy card; (ii) by telephone (from the United States, United States Territory and Canada) using the toll-free telephone number listed on the enclosed proxy card; or (iii) by completing, signing, dating and returning the enclosed proxy card in the postage-paid envelope provided. If your shares are held in the name of a bank, broker or other nominee, follow the instructions you receive from your nominee on how to vote your shares. Registered stockholders who attend the Quidel Stockholders’ Meeting may vote their shares in person even if they previously have voted their shares.

Voting in Person

Only Quidel stockholders as of the close of business on the record date or holders of a valid proxy for the meeting are entitled to attend the virtual Quidel Stockholders’ Meeting. Virtual attendance by stockholders of record at the Quidel Stockholders’ Meeting will constitute presence in person for the purpose of determining the presence of a quorum for the transaction of business at the Quidel Stockholders’ Meeting. You will be able to attend the Quidel Stockholders’ Meeting, as well as vote and submit your questions during the live webcast of the meeting by visiting www.virtualshareholdermeeting.com/QDEL2022SM and entering the 16-digit control number included on your proxy card.

Voting of Proxies

When you provide your proxy, the Quidel Shares represented by the proxy will be voted in accordance with your instructions. If you sign your proxy card without giving instructions, you will have granted authority to [•] to vote “FOR” each of the Merger Proposal, the Advisory Merger Compensation Proposal, the Adjournment Proposal, the Election of Directors Proposal, the Advisory Executive Compensation Proposal, the Independent Registered Public Accounting Firm Proposal, the Equity Incentive Plan Proposal, and the ESPP Proposal. Any proxy that is marked “AGAINST” the Merger Proposal will not be voted “FOR” the Adjournment Proposal. In all cases, the delivery of a signed proxy card shall confer authority upon the proxyholders to vote your shares in accordance with their judgment on any other matters properly presented at the Quidel Stockholders’ Meeting. The Quidel board of directors currently knows of no other business that will be presented for consideration at the Quidel Stockholders’ Meeting.

119

Revocation of Proxies

If you are a stockholder of record, you may revoke your proxy at any time before it is exercised in any one of four ways:

| • |  | by giving written notice to the Secretary of Quidel,

| • |  | by submitting a subsequently dated and properly signed proxy card in accordance with the instructions in this joint proxy statement/prospectus,

Quidel will reimburse brokers, banks or other custodians, nominees and fiduciaries for their charges and expenses in forwarding proxy material to beneficial owners. Quidel has engaged Innisfree M&A Incorporated to assist in the solicitation of proxies and provide related advice and informational support in connection with the Quidel Stockholders’ Meeting, for a service fee and the reimbursement of customary disbursements that are not expected to exceed $75,000 in the aggregate. All such expenses will be borne by Quidel.

Adjournments

The Chair of the Quidel Stockholders’ Meeting or the Quidel stockholders who hold a majority of the issued and outstanding Quidel Shares, present in person or represented by proxy, at the Quidel Stockholders’ Meeting, whether or not a quorum is present, has the power to adjourn the Quidel Stockholders’ Meeting until a later date and time. If the date and time of the adjourned meeting is given and the adjournment is for 30 days or less, no notice of the adjourned meeting need be given. At the adjourned Quidel Stockholders’ Meeting, if a quorum is present, Quidel may transact any business which might have been transacted at the original Quidel Stockholders’ Meeting.

Quidel Proposal No. 1—The Merger Proposal

(Item 1 on the Quidel proxy card)

This joint proxy statement/prospectus is being furnished to you as a stockholder of Quidel as part of the solicitation of proxies by the Quidel board of directors for use at the Quidel Stockholders’ Meeting to consider and vote upon a proposal to adopt the BCA, which is attached as Annex A to this joint proxy statement/prospectus.

The Quidel Merger cannot be completed without the approval of the Merger Proposal by the affirmative vote of the holders of a majority of the outstanding Quidel Shares entitled to vote on such proposal. If you are present in person or represented by proxy at the meeting but do not vote, or if you abstain, the effect will be the same as a vote “AGAINST” the Merger Proposal.

120

The Quidel board of directors, after due and careful discussions and consideration, has determined that the transactions to be implemented pursuant to the BCA, including the Quidel Merger and the other transactions contemplated by the BCA, are consistent with and will further the business strategies and goals of Quidel, and are in the best interests of Quidel and its stockholders, and (a) has unanimously approved and declared advisable the BCA and Combinations, including the Quidel Merger and the transactions contemplated by the BCA, and (b) has determined, subject to its duties under applicable law, to recommend that the Quidel stockholders adopt the BCA and the transactions contemplated by the BCA.

THE QUIDEL BOARD OF DIRECTORS ACCORDINGLY RECOMMENDS THAT QUIDEL STOCKHOLDERS VOTE “FOR” THE MERGER PROPOSAL.

Quidel Proposal No. 2—The Advisory Merger Compensation Proposal

(Item 2 on the Quidel proxy card)

The Dodd-Frank Wall Street Reform and Consumer Protection Act, enacted in July 2010, requires that Quidel provide its stockholders with the opportunity to cast a non-binding, advisory vote on the compensation that would be paid or become payable to Quidel’s named executive officers that is based on or otherwise relates to the proposed Combinations, as disclosed in this joint proxy statement/prospectus, including the disclosures set forth in the section entitled “Interests of Certain Persons in the Combinations (Quidel)—Golden Parachute Compensation” of this joint proxy statement/prospectus. This non-binding, advisory vote is commonly referred to as a “golden parachute say on pay” vote. This non-binding, advisory vote relates only to contractual obligations of Quidel that may result in a payment to Quidel’s named executive officers in connection with, or following, the consummation of the proposed Combinations and does not relate to any compensation arrangement with Quidel’s directors or executive officers who are not named executive officers.

As an advisory vote, this proposal is not binding upon Quidel or the Quidel board of directors, and approval of this proposal is not a condition to completion of the Combinations or Quidel’s, Ortho’s or Topco’s obligations to effect the Combinations. The vote on executive compensation payable in connection with the proposed Combinations is a vote separate and apart from the vote to approve the Merger Proposal. Accordingly, you may vote to approve the Merger Proposal, but vote not to approve the Advisory Merger Compensation Proposal. Because the vote is advisory, it will not be binding on Quidel. Accordingly, to the extent that Quidel is contractually obligated to pay certain merger-related compensation, such compensation will be payable, subject only to the contractual conditions applicable thereto, if the Combinations are consummated and regardless of the outcome of the advisory vote.

Approval of the Advisory Merger Compensation Proposal requires the affirmative vote of a majority of the voting power represented at the Quidel Stockholders’ Meeting in person or by proxy and entitled to vote on such proposal. If you are present in person or represented by proxy at the meeting but do not vote, or if you abstain, the effect will be the same as a vote “AGAINST” the Advisory Merger Compensation Proposal.

THE QUIDEL BOARD OF DIRECTORS RECOMMENDS THAT QUIDEL STOCKHOLDERS VOTE “FOR” THE ADVISORY MERGER COMPENSATION PROPOSAL.

Quidel Proposal No. 3—The Adjournment Proposal

(Item 3 on the Quidel proxy card)

At the Quidel Stockholders’ Meeting, Quidel stockholders (whether voting in person or by proxy) may be asked to vote on a proposal to adjourn the Quidel Stockholders’ Meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the Quidel Stockholders’ Meeting to approve the Merger Proposal. Quidel is asking that you authorize the holder of your proxy to vote in favor of any such Adjournment Proposal.

Approval of the Adjournment Proposal requires the affirmative vote of a majority of the voting power represented at the Quidel Stockholders’ Meeting in person or by proxy and entitled to vote on such proposal. If you are present in person or represented by proxy at the meeting but do not vote, or if you abstain, the effect will be the same as a vote “AGAINST” the Adjournment Proposal.

Quidel Proposal No. 5—The Advisory Executive Compensation Proposal

(Item 5 on the Quidel proxy card)

Quidel is providing its stockholders with an advisory (non-binding) vote on the compensation of Quidel’s named executive officers (“NEOs”) (commonly referred to as “say on pay”). Accordingly, you may vote on the following resolution at the Quidel Stockholders’ Meeting:

“Resolved, that the compensation paid to Quidel’s NEOs, as disclosed in the section entitled “Other Matters Relating to the Quidel Stockholders’ Meeting—Compensation Discussion and Analysis,” the accompanying compensation tables, and the related narrative discussion in this joint proxy statement/prospectus, is hereby approved.”

The advisory approval of Quidel’s executive compensation is a non-binding vote on the compensation paid to Quidel’s NEOs, as described pursuant to Item 402 of Regulation S-K, including the section entitled “Other Matters Relating to the Quidel Stockholders’ Meeting—Executive Compensation—Compensation Discussion and Analysis,” the accompanying compensation tables, and the related narrative discussion set forth in this joint proxy statement/prospectus. At Quidel’s

125

annual meeting of stockholders in 2017, Quidel stockholders overwhelmingly indicated a preference for holding annual say on pay votes. Accordingly, Quidel is presenting this proposal for the advisory approval of the compensation of Quidel’s NEOs.

As described in detail under the section entitled “Other Matters Relating to the Quidel Stockholders’ Meeting—Executive Compensation—Compensation Discussion and Analysis,” Quidel’s compensation programs are designed to attract, motivate and retain highly qualified executive officers who are able to achieve corporate objectives and create stockholder value. The compensation committee of the Quidel board of directors believes Quidel’s executive compensation programs reflect a strong pay-for-performance philosophy and are well aligned with Quidel stockholders’ long-term interests. Quidel stockholders are encouraged to read the section entitled “Other Matters Relating to the Quidel Stockholders’ Meeting—Executive Compensation—Compensation Discussion and Analysis” of this joint proxy statement/prospectus, the accompanying compensation tables, and the related narrative discussion.

Because the vote on this proposal is advisory in nature, it will not affect any compensation already paid or awarded to Quidel’s NEOs and will not be binding on the Quidel board of directors or its compensation committee. However, the compensation committee of the Quidel board of directors will consider the outcome of the vote when making future executive compensation decisions.

Vote Required and Board Recommendation

Approval of the Advisory Executive Compensation Proposal requires the affirmative vote of a majority of the voting power represented at the Quidel Stockholders’ Meeting in person or by proxy and entitled to vote on such proposal. If you are present in person or represented by proxy at the meeting but do not vote, or if you abstain, the effect will be the same as a vote “AGAINST” the Advisory Executive Compensation Proposal.

THE QUIDEL BOARD OF DIRECTORS RECOMMENDS THAT QUIDEL STOCKHOLDERS VOTE “FOR” THE ADVISORY EXECUTIVE COMPENSATION PROPOSAL.

Quidel Proposal No. 6—The Independent Registered Public Accounting Firm Proposal

(Item 6 on the Quidel proxy card)

The audit committee of the Quidel board of directors has selected the firm of Ernst & Young LLP, independent registered public accounting firm, to audit Quidel’s consolidated financial statements for the fiscal year ending December 31, 2022 and to perform other appropriate accounting and tax services. Quidel is asking its stockholders to ratify the selection of Ernst & Young LLP as Quidel’s independent registered public accounting firm for 2022. Although ratification is not required by the Quidel Bylaws or otherwise, the Quidel board of directors is submitting the selection of Ernst & Young LLP to Quidel stockholders as a matter of good corporate practice. If Quidel stockholders do not ratify the appointment of Ernst & Young LLP, the selection of Quidel’s independent registered public accounting firm will be reconsidered by the audit committee of the Quidel board of directors. Even if the selection is ratified, the audit committee of the Quidel board of directors, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of Quidel and its stockholders. After consummation of the Combinations, the Topco board of directors will select an independent registered public accounting firm as its independent registered public accounting firm for fiscal year 2022.

One or more representatives of Ernst & Young LLP are expected to attend the Quidel Stockholders’ Meeting. The representatives of Ernst & Young LLP will have an opportunity to make a statement, if they so desire, and will be available to respond to appropriate questions.

Vote Required and Board Recommendation

Approval of the Independent Registered Public Accounting Firm Proposal requires the affirmative vote of a majority of the voting power represented at the Quidel Stockholders’ Meeting in person or by proxy and entitled to vote on such proposal. If you are present in person or represented by proxy at the meeting but do not vote, or if you abstain, the effect will be the same as a vote “AGAINST” the Independent Registered Public Accounting Firm Proposal.

THE QUIDEL BOARD OF DIRECTORS RECOMMENDS THAT QUIDEL STOCKHOLDERS VOTE “FOR” THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM PROPOSAL.

Quidel Proposal No. 7—The Equity Incentive Plan Proposal

(Item 7 on the Quidel proxy card)

On March 4, 2022, the Quidel board of directors authorized, subject to Quidel stockholder approval, an amendment and restatement of Quidel’s 2018 Equity Incentive Plan (the “2018 Plan”), which 2018 Plan was previously approved by Quidel stockholders in May 2018, to increase the number of Quidel Shares available under the 2018 Plan from 3,205,635 shares to 4,705,635 shares and to make certain other ministerial changes to the 2018 Plan. The purpose of this amendment is to allow Quidel to continue to utilize the 2018 Plan and accordingly, to provide Quidel with flexibility in attracting employees in the future. Approval of the Equity Incentive Plan Proposal will enable Quidel to continue to use equity compensation for these purposes.

| • |  | Upon consummation of the Combinations, the 2018 Plan will be assumed by Topco and a number of Topco Shares equal to the number of Quidel Shares subject to the 2018 Plan will be issuable under the 2018 Plan following the consummation of the Combinations.

| • |  | If the Combinations are not consummated, the Quidel board of directors has approved a reduction in the number of Quidel Shares available for future issuance under the 2018 Plan to 4,205,635 shares.

As of March 4, 2022, there were 830,893 Quidel Stock Options, 729,277 Quidel RSUs and 19,642 Quidel PSUs outstanding under the Quidel Stock Plans and 1,350,265 shares remained available for future issuance under the 2018 Plan. As of March 4, 2022, the weighted average exercise price of the outstanding options was $69.84 with a weighted average remaining term of 6.54 years. Other than the foregoing, no other awards under the Quidel Stock Plans were outstanding as of March 4, 2022. The potential dilution from the 1,500,000 “new” shares requested to be approved by Quidel’s stockholders is 3.6% of outstanding Quidel Shares as of March 4, 2022. The potential dilution from the 2,930,077 shares currently authorized for issuance under the 2018 Plan reflects 7.0% of outstanding Quidel Shares as of March 4, 2022. Therefore, if the Equity Incentive Plan Proposal is approved, Quidel’s total potential dilution would increase from 7.0% of outstanding Quidel Shares as of March 4, 2022 to 10.6% of outstanding Quidel Shares as of March 4, 2022. Upon consummation of the Combinations, the potential dilution would be decreased to 6.6% of outstanding Topco Shares, based on the number of outstanding Quidel Shares and Ortho Shares as of March 4, 2022. In the event the Combinations are not consummated and the number of shares available for future issuance is reduced as described above, the potential dilution would be decreased to 9.4%.

Quidel considers its long-term dilution by managing the number of shares subject to equity awards that it grants annually, commonly referred to as the burn rate (calculated by dividing all shares subject to equity awards granted during the fiscal year by the number of outstanding shares at the end of the fiscal year). The burn rate shows how rapidly a company is depleting its shares reserved for future issuance under its equity compensation plans. Over the past three fiscal years, Quidel’s burn rate has averaged 1.3% (0.8% in fiscal year 2021, 1.5% in fiscal year 2020 and 1.8% in fiscal year 2019). Quidel believes that this burn rate is relatively low.

When considering the increase in the number of shares under the 2018 Plan to be approved, the compensation committee of the Quidel board of directors also reviewed, among other things, projected future share usage and projected future forfeitures, in each case assuming the Combinations are consummated. The projected future usage of shares for long-term incentive awards under the 2018 Plan was reviewed under scenarios based on a variety of assumptions, including the consummation of the Combinations. Depending on these assumptions, the 1,500,000 share increase to be approved under the 2018 Plan, in combination with the remaining authorized shares and shares potentially available under the 2018 Plan from forfeitures of awards previously granted under the 2018 Plan and prior plans, is expected to satisfy Topco’s equity compensation needs for approximately three years. The compensation committee of the Quidel board of directors is committed to effectively managing the number of shares reserved for issuance under the 2018 Plan, in light of the 2018 Plan’s purposes, while minimizing stockholder dilution.

As noted above, upon consummation of the Combinations, the 2018 Plan will be assumed by Topco. As of March 4, 2022, on an as-converted basis assuming consummation of the Combinations, there were 1,337,238 Ortho Stock Options, 36,808 unvested RSUs, 17,539 RSUs outstanding under Ortho’s equity compensation plans, and 1,632,945 Ortho Shares remained available for future issuance under Ortho’s equity compensation plans. As of March 4, 2022, the weighted average exercise price of the outstanding Ortho Stock Options was $11.51 with a weighted average remaining term of 6.76 years. Other than the foregoing, no other awards under Ortho’s equity compensation plans were outstanding as of March 4, 2022. Following the

127

consummation of the Combinations, if the Equity Incentive Plan Proposal is approved by the Quidel stockholders, no additional awards will be granted under Ortho’s equity compensation plans.

Summary of the 2018 Plan

The following summary is a description of the material features of the 2018 Plan, as proposed to be amended and restated, and is qualified in its entirety by reference to the full text of the 2018 Plan, as proposed to be amended and restated, a copy of which is attached hereto as Annex G.

Purpose. The purpose of the 2018 Plan is to promote Quidel’s and its stockholders’ interests by using equity interests in Quidel to attract, retain and motivate its directors, management, employees and other persons, to encourage and reward their contributions to Quidel’s performance and to align their interests with the interests of Quidel’s stockholders.

Administration, Amendment and Termination. The 2018 Plan is administered by the compensation committee of the Quidel board of directors (the “administrator”). The administrator has the power to:

| • |  | select the eligible persons to whom, and the times at which, awards will be granted, the nature of each award and the terms and conditions of each award;

| • |  | interpret the 2018 Plan and the rights of recipients of awards granted under the 2018 Plan; and

| • |  | accelerate or extend the vesting or exercise period of any award, and make such other modifications in the terms and conditions of an award as it deems advisable; provided, however, that the administrator may not, other than in connection with a change in capitalization, reprice or otherwise reduce the exercise or base price of a Quidel Stock Option or stock appreciation right (including by the cancellation of the Quidel Stock Option or stock appreciation right in exchange for cash, other awards, or a new Quidel Stock Option or stock appreciation right at such reduced exercise or base price or by amendment of the Quidel Stock Option or stock appreciation right) without stockholder approval.

Any amendment of the 2018 Plan shall, in the discretion of the administrator, apply to and govern awards granted under the 2018 Plan prior to the date of such amendment; provided, however, that the consent of an award holder is required if such amendment would alter, impair or diminish in any material respect any rights or obligations under any award or cause the award to cease to qualify as an incentive stock option. Awards may be granted under the 2018 Plan until May 15, 2028, unless earlier terminated.

Securities Subject to the 2018 Plan. The aggregate number of Quidel Shares issuable pursuant to the 2018 Plan, as proposed to be amended and restated, may not exceed 3,150,000 shares, plus (i) any shares that were authorized for issuance under Quidel’s 2016 Equity Incentive Plan that, as of May 15, 2018, remained available for issuance under the 2016 Equity Incentive Plan (not including any shares that are subject to outstanding awards under the 2016 Equity Incentive Plan or any shares that previously were issued pursuant to awards granted under the 2016 Equity Incentive Plan) and (ii) any shares subject to outstanding awards under Quidel’s 2001 Equity Incentive Plan, Amended and Restated 2010 Equity Incentive Plan, and 2016 Equity Incentive Plan as of May 15, 2018, that on or after such date ceased for any reason to be subject to such awards (other than by reason of exercise or settlement of the awards to the extent they are exercised for or settled in vested and nonforfeitable shares), subject in each case to adjustment upon a change in capitalization.

As noted above, as of March 4, 2022, 1,350,265 Quidel Shares remained available for issuance for future awards under the 2018 Plan. Accordingly, if the Equity Incentive Plan Proposal is approved by Quidel’s stockholders, approximately 2,850,265 shares will be available for future awards under the 2018 Plan, consisting of 1,500,000 new shares and approximately 1,350,265 remaining shares previously authorized and available for issuance under the 2018 Plan (as of March 4, 2022).

The 2018 Plan provides that each share issued under awards other than Quidel Stock Options or stock appreciation rights (“full-value awards”) will count against the number of shares available under the 2018 Plan as 1.5 shares. Shares issued under Quidel Stock Options or stock appreciation rights count against the shares available under the 2018 Plan on a one-for-one basis. The Quidel board of directors believes that this formula-based limit will allow for the issuance of a sufficient number of full-value awards to satisfy projected grants thereof, while providing the flexibility to change the mix of Quidel Stock Options and full-value awards to the extent its compensation committee determines a different mix than currently provided is in the best interests of Quidel and its stockholders.

128

Quidel may issue Quidel Shares under the 2018 Plan from authorized but unissued Quidel Shares or from previously issued Quidel Shares that it reacquired, including shares purchased on the open market. For purposes of calculating the aggregate number of shares issued under the 2018 Plan, Quidel will count only the number of shares issued upon exercise or settlement of an award and not returned to Quidel upon expiration, termination or cancellation of any awards. However, if an award holder pays the exercise price or withholding taxes relating to a Quidel Stock Option or stock appreciation right with Quidel Shares, or if Quidel withholds shares otherwise issuable upon exercise of a Quidel Stock Option or stock appreciation right in satisfaction of the exercise price or withholding taxes payment, then Quidel will reduce the number of Quidel Shares available for issuance under the 2018 Plan by the gross number of shares for which the award is exercised. In addition, upon the exercise of a Quidel Stock Option or stock appreciation right, the number of Quidel Shares available for issuance under the 2018 Plan will be reduced by the gross number of shares to which the award relates and not by the net number of shares issued to the holder in settlement thereof.

The 2018 Plan provides that the administrator shall appropriately and proportionately adjust the maximum number and kind of shares subject to the 2018 Plan, the number and kind of shares or other securities subject to then outstanding awards, the price for each share or other unit of any other securities subject to, or measurement criteria applicable to, then outstanding awards, and/or the number and kind of shares or other securities to be issued as non-employee director options if Quidel Shares are affected by any of the following:

| • |  | merger;

| • |  | consolidation;

| • |  | sale or exchange of assets;

| • |  | recapitalization;

| • |  | reclassification;

| • |  | combination;

| • |  | stock dividend;

| • |  | extraordinary cash dividend;

| • |  | stock split;

| • |  | reverse stock split;

| • |  | spin off; or

| • |  | similar transaction.

As noted above, upon consummation of the Combinations, the 2018 Plan will be assumed by Topco and the Quidel Shares subject to the 2018 Plan will be replaced by an equivalent number of Topco Shares.

Awards Under the 2018 Plan. Quidel may grant the following types of awards under the 2018 Plan:

| • |  | Quidel Stock Options;

| • |  | performance awards;

| • |  | restricted stock;

| • |  | stock appreciation rights;

| • |  | stock payments;

| • |  | dividend equivalents and dividends;

| • |  | stock bonuses;

| • |  | stock sales;

| • |  | phantom stock;

| • |  | Quidel RSUs;

129

| • |  | Quidel PSUs; or

| • |  | other stock-based benefits.

Quidel Stock Options granted under the 2018 Plan may be incentive stock options intended to qualify under the provisions of Section 422 of the Code or nonqualified stock options that do not so qualify. However, the aggregate fair market value of stock with respect to which any employee’s incentive stock options first become exercisable during any calendar year (under all Quidel Stock Plans and those of any subsidiary corporation) may not exceed $100,000 (as determined on the grant date), and may be further limited by other requirements in the Code. If this $100,000 limitation is exceeded, the excess incentive stock options will be treated as nonqualified stock options.

Individual Limitations on Awards. No non-employee director participant in the 2018 Plan may be granted cash and awards under the 2018 Plan that exceed $750,000 in total value during a single calendar year.

Eligibility. Quidel’s directors, officers, employees, consultants and advisors, and those of its affiliated entities, are eligible to receive awards under the 2018 Plan. As of March 4, 2022, 125 persons (not including consultants and advisors) were eligible for selection to receive awards under the 2018 Plan, consisting of: 109 employees of Quidel other than executive officers, 7 executive officers of Quidel and 9 non-employee directors of Quidel. To date, no consultants or advisors have been granted awards under the 2018 Plan. Following consummation of the Combinations, approximately 334 persons (not including consultants and advisors) are expected to be eligible for selection to receive awards under the 2018 Plan, consisting of: 323 employees of Topco (including executive officers) and 11 non-employee directors of Topco.

Terms and Conditions of Non-Employee Director Options. Non-employee directors of Quidel are eligible to receive grants of awards under the 2018 Plan, including nonqualified stock options, at the discretion of the administrator. Under the 2018 Plan, all grants of Quidel Stock Options to non-employee directors fully vest and become exercisable one year following the grant date if the non-employee director has remained a director for the entire period from the date of grant to the vesting date. Notwithstanding the foregoing, if the recipient has remained a director from the period of the date of grant until the next annual meeting of Quidel’s stockholders following the grant date, but ceases to be a director following the annual meeting of Quidel’s stockholders (either because the director is not re-elected or because the director chooses not to run for another term), the Quidel Stock Options that were granted to the director at the annual meeting in the prior year shall continue to vest following the date that the recipient ceases to be a director and shall become exercisable one year following the grant date.

Terms and Conditions of Other Awards. The administrator will select the recipients of awards granted under the 2018 Plan from the pool of eligible persons and will set the terms of the awards.

Award Pricing. The administrator will determine the exercise or purchase price of awards granted under the 2018 Plan, which, with respect to Quidel Stock Options and stock appreciation rights, will be no less than the fair market value of the shares underlying the award as of the grant date. In addition, the exercise price for an incentive stock option must comply with the provisions of Section 422 of the Code. Section 422 currently provides that the exercise price must not be less than the fair market value of the common stock on the date of grant and not less than 110% of the fair market value as of the date of grant in the case of a grant to a person owning more than 10% of the total combined voting power of all classes of the issuer’s stock or the stock of any parent or any subsidiary corporations. On March 4, 2022, the closing price of Quidel Shares on Nasdaq was $99.57 per share.

Award Vesting and Term. The administrator will determine the date or dates on which awards granted under the 2018 Plan vest and become exercisable. In addition, the administrator may provide for accelerated vesting upon a change in control or the recipient’s death or disability. The term of each Quidel Stock Option or stock appreciation right granted will expire no later than ten (10) years after the date the Quidel Stock Option or stock appreciation right is granted and may be subject to earlier termination as described below. In addition, the term for an incentive stock option must comply with the provisions of Section 422 of the Code. Section 422 currently provides that the incentive stock option may not be exercisable after the expiration of 10 years from the date of grant, or five years in the case of an incentive stock option granted to a person owning more than 10% of the total combined voting power of all classes of stock of the issuer, or of its parent or any subsidiary corporations.

Awards granted under the 2018 Plan may be exercised at any time after they vest and before the expiration date determined by the administrator; provided that an award is generally exercisable following an award holder’s termination of employment

130

only to the extent that the award had become exercisable on or before the date of termination (other than Quidel Stock Options granted to non-employee directors) and to the extent that the award is not forfeited under the terms of the 2018 Plan. Furthermore, in the absence of a specific agreement to the contrary, Quidel Stock Options will generally expire and become unexercisable immediately upon termination of the recipient’s employment with Quidel for just cause (as defined in the 2018 Plan); 90 days after termination of the recipient’s employment with Quidel for any reason other than just cause, death or permanent disability; or one year after termination of the recipient’s employment with Quidel due to death or permanent disability, in each case unless the term of the Quidel Stock Option provides for an earlier expiration. If the employment of a recipient of restricted stock is terminated for any reason, any such restricted stock that remains subject to restrictions on the date of such termination will be repurchased by Quidel at the purchase price, if any, paid by the recipient, or returned to Quidel without consideration; provided, however, that the administrator may in its discretion determine otherwise.

Other Award Provisions. The administrator will determine any applicable performance criteria, restrictions or conditions of any award. The administrator may establish performance criteria and level of achievement versus such criteria that will determine the number of shares to be granted, retained, vested, issued or issuable under or in settlement of or the amount payable pursuant to an award, which criteria may (but need not) be based on “performance criteria” (as described below) or other standards of financial performance and/or personal performance evaluations.

For purposes of the 2018 Plan, the term “performance criteria” means any one or more of the following performance criteria, or derivations of such performance criteria, either individually, alternatively or in any combination, applied to either Quidel as a whole or to a business unit or affiliated entity, either individually, alternatively or in any combination, and measured either annually (or over such shorter period) or cumulatively over a period of years, on an absolute basis or relative to a pre-established target, to previous years’ results or to a designated comparison group, in each case as specified by the administrator: (a) cash flow, (b) earnings and earnings per share (including earnings before interest, taxes, and amortization), (c) return on equity, (d) total stockholder return, (e) return on capital, (f) return on assets or net assets, (g) aggregate product price or product sales, (h) market share or market penetration with respect to specific designated products and/or geographic areas, (i) revenues, income or net income, (j) operating income or net operating income, (k) operating margin, (l) return on operating revenue and (m) research and development milestones.

Award Payments. A holder of an award may pay cash or any other consideration deemed acceptable by the administrator to pay the exercise price for the award, if any. The administrator may, in its discretion, allow an award holder to pay the exercise price for an award by delivering Quidel Shares, except in limited circumstances.

Non-Assignability of Awards. Awards are generally not transferable by the recipient during the life of the recipient. Awards are generally exercisable during the life of a recipient only by the recipient. The administrator may, on a case-by-case basis, permit transfers for estate planning purposes.

Award Documentation. Each award under the 2018 Plan must be evidenced by an award document setting forth such terms and conditions applicable to the award as the administrator may in its discretion determine.

Rights With Respect to Stock Ownership. No recipient of an award under the 2018 Plan or other person will have any right, title or interest in or to any Quidel Shares subject to any award or any rights as a stockholder, unless the award is duly exercised pursuant to the terms of the 2018 Plan and/or the Quidel Shares subject to the award are issued to the recipient and/or the restrictions on the Quidel Shares subject to any award lapse.

Provisions Regarding Changes in Control. As of the effective time and date of any change in control (as defined in the 2018 Plan), the 2018 Plan and any of the then outstanding awards (whether or not vested) will automatically terminate unless:

| • |  | provision is made in writing in connection with such change in control transaction for the continuance of the 2018 Plan and for the assumption of such awards, or for the substitution for such awards of new awards covering the securities of a successor entity or an affiliate thereof with appropriate adjustments as to the number and kind of securities and exercise prices or measurement criteria, in which event the 2018 Plan and such outstanding awards will continue or be replaced, as the case may be, in the manner and under the terms so provided; or

| • |  | the Quidel board of directors otherwise provides in writing for such adjustments as it deems appropriate in the terms and conditions of the then outstanding awards (whether or not vested), including without limitation accelerating the vesting of outstanding awards and/or providing for the cancellation of awards and their automatic conversion into the right to receive the securities, cash or other consideration that a holder of the shares underlying such awards would have been entitled to receive upon consummation of such change in control had such shares been issued and outstanding immediately prior to the effective date and time of the change in control (net of the appropriate option exercise prices).

131

If, pursuant to these provisions, the 2018 Plan and the awards terminate by reason of the occurrence of a change in control without provision for any of the actions described in the paragraph above, then any recipient holding outstanding awards will have the right, at such time immediately prior to the consummation of the change in control as the Quidel board of directors will designate, to exercise or receive the full benefit of the recipient’s awards to the full extent not theretofore exercised, including any installments that have not yet become vested. All non-employee director options granted under the 2018 Plan shall automatically vest and become exercisable immediately prior to a change in control if the optionee is a director of Quidel at that time.

The consummation of the Combinations will not be considered a change in control under the terms of the 2018 Plan.

Clawback. Every award issued under the 2018 Plan is subject to potential forfeiture or recovery to the fullest extent permitted by law, applicable listing standards or any current or future clawback policy adopted by Quidel.

2018 Plan Benefits

The issuance of any awards under the 2018 Plan will be at the discretion of the compensation committee of the Quidel board of directors. Therefore, it is not possible to determine the amount or form of any award that will be granted to any individual in the future. The following table sets forth the awards that were previously granted under the 2018 Plan through March 4, 2022 to Quidel’s named executive officers (“NEOs”) and others.

Tax Information

The following summary of certain federal income tax consequences of the receipt and exercise of awards is based on the laws and regulations in effect as of the date of this joint proxy statement/prospectus and does not purport to be a complete statement of the law in this area. Furthermore, the discussion below does not address the tax consequences of the receipt and exercise of awards under foreign, state and local tax laws, and such tax laws may not correspond to the federal income tax treatment described herein. The exact federal income tax treatment of transactions under the 2018 Plan will vary depending upon the specific facts and circumstances involved.

Incentive Stock Options. Except as discussed below, under federal income tax law, a recipient of an incentive stock option generally will not realize tax on the grant or the exercise of the option if the recipient satisfies certain employment and holding period requirements. To satisfy the employment requirement, a recipient must exercise the option not later than three months after the recipient ceases to be an employee of Quidel (or an employee of any parent or subsidiary corporation) (or within one year, if termination was due to a permanent and total disability), unless the recipient has died. To satisfy the holding period requirement, a recipient must hold the stock acquired upon the exercise of the incentive stock option for more than two years from the date of grant of the option and more than one year after the transfer of the shares to the recipient. If these requirements are met, the recipient will, on the sale of such stock, be taxed on any gain, measured by the difference between the option price and the net proceeds of sale, generally at long-term capital gains rates.

132

If the recipient of the incentive stock option sells the shares acquired upon the exercise of the option at any time within one year after the date Quidel issues the shares to the recipient or within two years after the date Quidel grants the incentive stock option to the recipient, then:

| • |  | if the recipient’s sales price exceeds the purchase price the recipient paid for the shares upon exercise of the incentive stock option, the recipient will recognize capital gain equal to the excess, if any, of the sales price over the fair market value of the shares on the date of exercise, and will recognize ordinary income equal to the excess, if any, of the lesser of the sales price or the fair market value of the shares on the date of exercise over the purchase price paid for the shares upon exercise of the incentive stock option; or

| • |  | if the recipient’s sales price is less than the purchase price paid for the shares upon exercise of the incentive stock option, the recipient will recognize a capital loss equal to the excess of the purchase price paid for the shares upon exercise of the incentive stock option over the sales price of the shares.

The amount by which the fair market value of shares the recipient acquires upon exercise of an incentive stock option (determined as of the date of exercise) exceeds the purchase price paid for the shares upon exercise of the incentive stock option will be included as a positive adjustment in the calculation of the recipient’s alternative minimum taxable income in the year of exercise, if the recipient is subject to alternative minimum tax.

In the case of an early disposition of shares by a recipient that results in the recognition of ordinary income, Quidel will be entitled to a deduction equal to the amount of such ordinary income. If the recipient holds the shares for the requisite period described above and therefore solely recognizes capital gain upon the sale of such shares, Quidel is not entitled to any deduction.

Nonqualified Stock Options. The grant of a nonqualified stock option to a recipient is generally not a taxable event for the recipient. Upon the exercise of a nonqualified stock option, the recipient will generally recognize ordinary income equal to the excess of the fair market value of the shares the recipient acquires upon exercise (determined as of the date of exercise) over the purchase price paid for the shares upon exercise of the nonqualified stock option, subject to the deduction limitations of Section 162(m) of the Code. Quidel generally will be entitled to deduct as a compensation expense the amount of such ordinary income. Provided the shares are held as a capital asset, the recipient’s subsequent sale of the shares generally will give rise to capital gain or loss equal to the difference between the sale price and the sum of the purchase price paid for the shares plus the ordinary income recognized with respect to the shares, and such capital gain or loss will be taxable as long-term or short-term capital gain or loss depending upon the recipient’s holding period after exercise.

Stock Appreciation Rights and Phantom Stock. Generally, the holder of a stock appreciation right or phantom stock award will recognize ordinary income equal to the value Quidel pays (whether in cash, stock or a combination thereof) on the date the holder receives payment. If Quidel places a limit on the amount that will be payable under a stock appreciation right, the holder may recognize ordinary income equal to the value of the holder’s right under the stock appreciation right at the time the value of such right equals such limit and the stock appreciation right is exercisable, subject to the deduction limitations of Section 162(m) of the Code. Quidel will generally be entitled to a deduction in an amount equal to the ordinary income recognized by the holder.

Stock Purchase Rights - Restricted Stock. Under the 2018 Plan, Quidel is authorized to grant rights to purchase its restricted common stock subject to a right to repurchase such stock at the price paid by the participant if the participant’s employment or service relationship with Quidel terminates prior to the lapse of such repurchase right. In general, there will be no tax consequences to a participant upon the grant of a right to purchase such restricted stock or upon purchase of such restricted stock. Instead, the participant will be taxed at ordinary income rates at the time Quidel’s repurchase rights expire or are removed on an amount equal to the excess of the fair market value of the stock at that time over the amount the participant paid to acquire such stock. A participant who acquires restricted stock, however, may make an election under Section 83(b) of the Code with respect to such stock. If such an election is made within 30 days after the participant’s acquisition of the stock, the participant is taxed at ordinary income rates in the year in which the participant acquires the restricted stock. The ordinary income the participant must recognize is equal to the excess of the fair market value of the stock at the time of the participant’s acquisition of the stock (determined without regard to the restrictions) over the amount that the participant paid to acquire such stock. If a participant makes a timely election under Section 83(b) of the Code with respect to restricted stock, the participant generally will not be required to report any additional income with respect to such restricted stock until he or she disposes of such stock, at which time he or she will generally recognize capital gain or loss (provided the shares are held as a capital asset) equal to the difference between the sales price and the fair market value of the stock at the time of the

133

participant’s acquisition of the stock (determined without regard to restrictions). In the event that a participant forfeits (as a result of Quidel’s repurchase) restricted stock with respect to which an election under Section 83(b) of the Code has been made, the participant ordinarily will not be entitled to recognize any loss for federal income tax purposes (except to the extent the amount realized by the participant at the time of such forfeiture is less than the participant’s purchase price for such stock). Subject to the deduction limitations of Section 162(m) of the Code, Quidel generally will be entitled to a deduction equal to the amount of ordinary income (if any) recognized by a participant.

Other Awards. In addition to the types of awards described above, the 2018 Plan authorizes certain other awards that may include payments in cash, Quidel Shares, or a combination of cash and Quidel Shares. The tax consequences of such awards will depend upon the specific terms of such awards. Generally, however, a participant who receives an award payable in cash will recognize ordinary income, and Quidel will, subject to the deduction limitations of Section 162(m) of the Code, be entitled to a deduction, with respect to such award at the earliest time at which the participant has an unrestricted right to receive the cash payment. In general, the sale or grant of stock to a participant under the 2018 Plan will be a taxable event at the time of the sale or grant if such stock at that time is not subject to a substantial risk of forfeiture or is transferable within the meaning of Section 83 of the Code in the hands of the participant. For such purposes, stock is ordinarily considered to be transferable if it can be transferred to another person who takes the stock free of any substantial risk of forfeiture. In such case, the participant will recognize ordinary income, and, subject to the deduction limitations of Section 162(m) of the Code, Quidel will be entitled to a deduction, equal to the excess of the fair market value of such stock on the date of the sale or grant over the amount, if any, that the participant paid for such stock. Stock that, at the time of receipt by a participant, is subject to restrictions that constitute a substantial risk of forfeiture and that is not transferable within the meaning of Section 83 of the Code generally will be taxed under the rules applicable to restricted stock as described above.

Withholding. In the event that an optionee or other recipient of an award under the 2018 Plan is an employee of Quidel, Quidel ordinarily will be required to withhold applicable federal income taxes with respect to any ordinary income recognized by such optionee or other award recipient in connection with Quidel Stock Options or other awards under the 2018 Plan.

Certain Additional Rules Applicable to Awards. The terms of the awards granted under the 2018 Plan may provide for accelerated vesting in connection with a change in control. In that event and depending upon the individual circumstances of the recipient, certain amounts with respect to such awards may constitute “excess parachute payments” under the “golden parachute” provisions of the Code. Under these provisions, a participant will be subject to a 20% excise tax on any “excess parachute payments” and Quidel will be denied any deduction with respect to such excise tax payment.

Participation in the 2018 Plan by Executive Officers, Directors and Other Employees; Interest of Certain Persons in Matters to be Acted Upon

Each of Quidel’s current directors, executive officers and employees is eligible to receive awards under the 2018 Plan. The administrator has the discretion to determine which eligible persons will receive awards under the 2018 Plan, though the amount and timing of such awards are not determinable at this time.

Vote Required and Board Recommendation

Approval of the Equity Incentive Plan Proposal requires the affirmative vote of a majority of the voting power represented at the Quidel Stockholders’ Meeting in person or by proxy and entitled to vote on such proposal. Abstentions have the same effect as a vote “AGAINST” the Equity Incentive Plan Proposal.

THE QUIDEL BOARD OF DIRECTORS RECOMMENDS THAT QUIDEL STOCKHOLDERS VOTE “FOR” THE EQUITY INCENTIVE PLAN PROPOSAL.

Quidel Proposal No. 8—The ESPP Proposal

(Item 8 on the Quidel proxy card)

On March 4, 2022, the Quidel board of directors authorized, subject to Quidel stockholder approval, an amendment and restatement of Quidel’s 1983 Employee Stock Purchase Plan (the “1983 ESPP”) to increase the number of Quidel Shares available under the 1983 ESPP from 30,197 shares to 780,197 shares. As of March 4, 2022, 669,803 Quidel Shares have been sold under the 1983 ESPP, leaving 30,197 shares available for future issuance under the 1983 ESPP. If the ESPP Proposal is approved, a total of 780,197 Quidel Shares will be available for future issuance under the 1983 ESPP, which amount

134

represents 1.9% of the total number of Quidel Shares outstanding as of March 4, 2022. Upon consummation of the Combinations, such would be decreased to 1.2% of outstanding Topco Shares, based on the number of outstanding Quidel Shares and Ortho Shares as of March 4, 2022. The purpose of this amendment is to allow Quidel to continue to utilize the 1983 ESPP and accordingly, to provide Quidel with flexibility in attracting employees in the future and to encourage employee ownership of Quidel common stock. Approval of the ESPP Proposal will enable Quidel to continue to use equity compensation for these purposes.

| • |  | Upon consummation of the Combinations, the 1983 ESPP will be assumed by Topco and a number of Topco Shares equal to the number of Quidel Shares subject to the 1983 ESPP will be issuable under the 1983 ESPP following the consummation of the Combinations.

| • |  | If the Combinations are not consummated, the Quidel board of directors has approved a reduction in the number of Quidel Shares available for future issuance under the 1983 ESPP to 530,197 shares.

Summary of the 1983 ESPP

The following summary is a description of the material features of the 1983 ESPP, as proposed to be amended and restated, and is qualified in its entirety by reference to the full text of the 1983 ESPP, as proposed to be amended and restated, a copy of which is attached hereto as Annex H.

General. The 1983 ESPP, which was adopted by the Quidel board of directors in March 1983 and approved by the Quidel stockholders in August 1983, provides Quidel employees with the opportunity to purchase Quidel Shares through payroll deductions. If the ESPP Proposal is approved, a total of 780,197 Quidel Shares will be reserved for issuance under the 1983 ESPP. As noted above, upon consummation of the Combinations, the 1983 ESPP will be assumed by Topco and the Quidel Shares subject to the 1983 ESPP will be replaced by an equivalent number of Topco Shares. Ortho does not have an employee stock purchase plan.

Administration. The 1983 ESPP is administered by the compensation committee of the Quidel board of directors. The 1983 ESPP and the right of participants to make purchases thereunder are intended to qualify under the provisions of Sections 421 and 423 of the Code.

Eligibility and Participation. Any person who is customarily employed by Quidel or any of its designated subsidiaries on or before the beginning of the applicable offering period for at least 20 hours per week and more than five months per calendar year is eligible to participate in the offering under the 1983 ESPP; provided that such person is employed by Quidel on the commencement date of the offering period, subject to certain limitations imposed by Section 423(b) of the Code and limitations on stock ownership as defined in the 1983 ESPP. As of March 4, 2022, 1,300 persons (not including consultants and advisors) were eligible to participate in the 1983 ESPP, consisting of: 1,293 employees of Quidel other than executive officers and 7 executive officers of Quidel. Following consummation of the Combinations, approximately 6,114 persons (not including consultants and advisors) are expected to be eligible to participate in the 1983 ESPP, consisting of: 6,114 employees of Topco (including executive officers).

Offering Dates. The 1983 ESPP is implemented by accumulating payroll deductions of participating employees during a six-month offering period, with the offering periods thereunder to commence February 15 and August 15 of each year. The Quidel board of directors has the power to alter the duration of the offering periods without stockholder approval, if such change is announced at least 15 days prior to the scheduled beginning of the first offering period to be affected.

Purchase Price. The purchase price per share at which shares are sold in an offering under the 1983 ESPP is the lower of 85% of the fair market value of a Quidel Share on the date of commencement of the six-month offering period (the “Entry Price”), or 85% of the fair market value of a Quidel Share on the last day of the offering period (the “Exit Price”). On March 4, 2022, the closing price of Quidel Shares on Nasdaq was $99.57 per share.

Payment of Purchase Price; Payroll Deductions. The purchase price of the shares is accumulated by payroll deductions over the offering period. The deductions may not exceed 10% of a participant’s compensation. A participant may discontinue his or her participation in the 1983 ESPP, and may decrease, but not increase, the rate of payroll deductions at any time during an offering period.

Purchase of Stock. By executing a subscription agreement to participate in the 1983 ESPP, the employee is entitled to have shares placed under option, which are exercisable on the last day of the offering period. The maximum number of shares

135

placed under option to a participant in an offering period is that number determined by dividing the amount accumulated in such participant’s account during such offering period at the end of the offering period by the lower of the Entry Price or the Exit Price, subject to a maximum of 5,000 shares. Unless the employee’s participation is discontinued prior to such purchase date, his or her option for the purchase of the shares will be exercised automatically at the end of the offering period at the applicable price. Notwithstanding the foregoing, however, no participant may receive an option (i) if immediately after such grant, the participant would own stock and/or outstanding options to purchase stock possessing 5% or more of the total combined voting power of all classes of stock of Quidel or of any subsidiary of Quidel, or (ii) which permits the participant’s rights to purchase stock to accrue at a rate in excess of $25,000 worth of stock (determined at the fair market value of the stock at the time such option is granted) in any calendar year.

Amendment and Termination. The Quidel board of directors may at any time terminate or amend the 1983 ESPP. No such termination will affect options previously granted, nor may any amendment make any change in any option previously granted which adversely affects the rights of any participant, nor may any amendment be made without prior stockholder approval if such amendment would (i) increase the number of shares that may be issued under the 1983 ESPP, (ii) permit payroll deductions at a rate in excess of 10% of compensation, (iii) modify employee eligibility for participation requirements, or (iv) materially increase benefits that may accrue to participants under the 1983 ESPP.

Non-Assignability. In general, neither payroll deductions credited to a participant’s account nor any rights with regard to the exercise of an option may be assigned, transferred, pledged or otherwise disposed of in any way by the participant.

Adjustments upon Changes in Capitalization. Subject to any required action by Quidel stockholders, the number of Quidel Shares covered by each option that has not yet been exercised and the number of Quidel Shares that have been authorized for issuance under the 1983 ESPP but have not yet been placed under option, as well as the price per Quidel Share covered by each outstanding option, shall be proportionately adjusted for any increase or decrease in the number of issued Quidel Shares resulting from a stock split or the payment of a stock dividend (but only on Quidel common stock) or any other increase or decrease in the number of Quidel Shares effected without receipt of consideration by Quidel; provided that the conversion of convertible securities of Quidel will not be deemed to have been effected without the receipt of consideration. In the event that Quidel effects a reorganization, recapitalization, rights offering or other increase or decrease of outstanding Quidel Shares , or in the event that Quidel is consolidated with or merged into any other corporation, the Quidel board of directors may, if it so determines in the exercise of its discretion, make similar adjustments. As noted above, upon consummation of the Combinations, the 1983 ESPP will be assumed by Topco and the Quidel Shares subject to the 1983 ESPP shall be replaced by an equivalent number of Topco Shares.

Withdrawal; Termination of Employment. A participant’s interest in a given offering period may be terminated in whole, but not in part, by signing and delivering to Quidel a notice of withdrawal from the 1983 ESPP . Such withdrawal may be elected at any time prior to the end of the applicable six-month offering period. A participant’s withdrawal from one offering period does not have any effect upon such participant’s eligibility to participate in subsequent offerings. Upon withdrawal from an offering period, all payroll deductions that have been credited to the participant’s account prior to the notice of withdrawal will be returned to the participant without interest.

Termination of a participant’s employment for any reason, including retirement or death, or the failure of the participant to remain in Quidel’s continuous employ for at least 20 hours per week during the applicable offering period, cancels the participant’s participation in the 1983 ESPP. In such event, the payroll deductions credited to the participant’s account will be returned to such participant or to his or her beneficiaries without interest.

Compliance with Law. Shares will not be issued with respect to an option unless the exercise of such option and the issuance and delivery of such shares pursuant thereto comply with all applicable provisions of law, including securities laws and the requirements of any stock exchange upon which the shares may then be listed.

Tax Information

The following summary of certain federal income tax consequences of the grant and exercise of rights to purchase Quidel Shares under the 1983 ESPP is based on the laws and regulations in effect as of the date of this joint proxy statement/prospectus and does not purport to be a complete statement of the law in this area. Furthermore, the discussion below does not address the tax consequences under foreign, state and local tax laws, and such tax laws may not correspond to the federal income tax treatment described herein. The exact federal income tax treatment of transactions under the 1983 ESPP will vary depending upon the specific facts and circumstances involved.

136

The 1983 ESPP is intended to qualify as an employee stock purchase plan under Section 423 of the Code. If certain employment requirements are satisfied, an employee who is granted a right, or “option,” to purchase stock under a plan meeting the requirements of Section 423 of the Code will not be subject to federal income tax, and Quidel will not be entitled to any deduction, on either the grant or the exercise of such right.

If the employee makes no disposition of the stock acquired pursuant to the exercise of such right within two years after the date of the grant of such stock purchase right (generally, the commencement date of the six-month offering period, hereinafter referred to as the “Offering Date”) or within one year after the transfer of the stock to the employee pursuant to the exercise of such right, any gain or loss on the subsequent disposition of the stock generally will be treated as capital gain or loss, except to the extent that the employee’s purchase price was less than 100% of the fair market value of the stock on the Offering Date, and no deduction will be available to Quidel at the time of such disposition. If the employee’s purchase price for the stock was less than 100% of the fair market value of the stock on the Offering Date, the employee will be required to include in his or her gross income as ordinary income for the year of the disposition (or, if earlier, at the time of his or her death) an amount equal to the lesser of (i) the excess of the fair market value of the stock on the Offering Date over the purchase price that the employee would have been required to pay if the employee had exercised such right as of the Offering Date, or (ii) the excess of the fair market value of the stock at the time of the disposition or death over the amount paid for the stock. No deduction will be available to Quidel with respect to any such ordinary income recognized by the employee.

Any sale or other disposition of stock acquired under a right granted under the 1983 ESPP at any time within (i) two years after the Offering Date or (ii) one year after the transfer of the shares to the employee pursuant to the exercise of such right generally will be treated as a “disqualifying disposition.” Upon a disqualifying disposition, the employee generally will recognize ordinary compensation income in an amount equal to the difference between the purchase price and the fair market value of the stock on the date the option was exercised. Any gain in excess of such ordinary income amount generally will be capital gain. Quidel generally will be entitled to a deduction in an amount equal to the amount of ordinary income recognized by the employee by reason of a disqualifying disposition.

Participation in the 1983 ESPP by Executive Officers, Directors and Other Employees; Interest of Certain Persons in Matters to be Acted Upon

All of Quidel’s employees, including its employee-directors and executive officers, who satisfy the eligibility requirements described above are eligible to participate in the 1983 ESPP. Non-employee directors are not eligible to participate. Participation in the 1983 ESPP is voluntary and is dependent on each eligible employee’s election to participate and his or her determination as to the level of payroll deductions. Accordingly, future purchases by executive officers and other employees under the 1983 ESPP are not determinable. The following table sets forth the number of Quidel Shares purchased under the 1983 ESPP through February 14, 2022 (the most recent purchase date) by Quidel’s NEOs and others.

Name and Position |  | Number of Quidel Shares |
Douglas C. Bryant, President and Chief Executive Officer |  |  | 13,067 |
Randall J. Steward, Chief Financial Officer |  |  | — |
Robert J. Bujarski, Chief Operating Officer |  |  | — |

All non-employee directors as a group |  |  | — |
All employees as a group (excluding executive officers) |  |  | 645,939 |

Vote Required and Board Recommendation

Approval of the ESPP Proposal requires the affirmative vote of a majority of the voting power represented at the Quidel Stockholders’ Meeting in person or by proxy and entitled to vote on such proposal. Abstentions have the same effect as a vote “AGAINST” the ESPP Proposal.

THE QUIDEL BOARD OF DIRECTORS RECOMMENDS THAT QUIDEL STOCKHOLDERS VOTE “FOR” THE ESPP PROPOSAL.

Audit Committee

The Audit Committee is responsible for assisting the Quidel board of directors in overseeing Quidel’s accounting and financial reporting processes and the audits of Quidel’s consolidated financial statements. In addition, the Audit Committee assists the Quidel board of directors in its oversight of its compliance with legal and regulatory requirements. Under the Audit Committee’s written charter, the specific duties of the Audit Committee include, among others: monitoring the integrity of Quidel’s financial process and systems of internal controls regarding finance, accounting and legal compliance; selecting Quidel’s independent registered public accounting firm; monitoring the independence and performance of Quidel’s independent registered public accounting firm; and providing an avenue of communication among Quidel’s independent registered public accounting firm, management and the Quidel board of directors. The Audit Committee has the authority to conduct any investigation appropriate to fulfilling its responsibilities, and it has direct access to all of Quidel’s employees and to the independent registered public accounting firm. The Audit Committee also has the ability to retain, at Quidel’s expense and without further approval of the Quidel board of directors, legal, accounting or other consultants or experts that it deems necessary in the performance of its duties.

The Audit Committee has been established in accordance with applicable Nasdaq and SEC rules and regulations. The Quidel board of directors has also determined that Ms. Rhoads and Mr. Slacik each qualify as an “audit committee financial expert” within the meaning of the SEC’s rules and regulations.

Report of the Audit Committee of the Quidel Board of Directors

The Audit Committee oversees Quidel’s financial reporting process on behalf of the Quidel board of directors. Management has the responsibility for preparing the consolidated financial statements and for the reporting process, including the Quidel’s systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed the audited consolidated financial statements in Quidel’s Annual Report on Form 10-K for the year ended December 31, 2021 with management, including a discussion of the quality, not just the acceptability, of accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the consolidated financial statements.

138

The Audit Committee has discussed and reviewed with Quidel’s independent registered public accounting firm all matters required to be discussed under the Public Company Accounting Oversight Board (“PCAOB”) Accounting Standard No. 1301 (Communications with Audit Committees), as may be modified or supplemented. The Audit Committee has met with the independent registered public accounting firm to discuss the overall scope and plans for the independent registered public accounting firm’s audit, the results of its examinations, its evaluations of Quidel’s internal controls and the overall quality of Quidel’s accounting and financial reporting. The Audit Committee also discussed with the independent registered public accounting firm the firm’s judgments as to the substance and clarity, not just the acceptability, of Quidel’s accounting principles and financial statement disclosures. The Audit Committee has also considered whether the independent registered public accounting firm’s provision of non-audit services to Quidel is compatible with the independent registered public accounting firm’s independence.

The Audit Committee also reviewed management’s report on its assessment of the effectiveness of Quidel’s internal control over financial reporting and Ernst & Young LLP’s report on the effectiveness of Quidel’s internal control over financial reporting.

The Audit Committee has received from the independent registered public accounting firm a formal written statement describing all relationships between the independent registered public accounting firm and Quidel that might bear on the independent registered public accounting firm’s independence consistent with PCAOB Rule 3526 (Communication with Audit Committees Concerning Independence), has discussed with the independent registered public accounting firm any relationships that may impact its objectivity and independence, and has satisfied itself as to the independent registered public accounting firm’s independence.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Quidel board of directors (and the Quidel board of directors has approved) that the audited consolidated financial statements be included in Quidel’s Annual Report on Form 10-K for the year ended December 31, 2021.

Policy on Audit Committee Pre-approval of Audit and Permissible Non-audit Services

The Audit Committee is responsible for appointing, compensating, retaining and overseeing the work of Quidel’s independent registered public accounting firm. The Audit Committee’s policy is to pre-approve all audit and permissible non-audit services provided by Quidel’s independent registered public accounting firm. Pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget. The Audit Committee may also pre-approve particular services on a case-by-case basis. In assessing requests for services to be provided by Quidel’s independent registered public accounting firm, the Audit Committee considers whether such services are consistent with the auditor’s independence, whether the independent registered public accounting firm is likely to provide the most effective and efficient services, and whether the services could enhance Quidel’s ability to manage or control risk or improve audit quality.

All of the audit, audit-related, tax and other fees provided by Ernst & Young LLP in fiscal years 2021 and 2020 (and as described in the footnotes to the table above) were approved in advance by the Audit Committee.

Review and Approval of Related Party Transactions

The Audit Committee reviews all relationships, transactions and arrangements in which Quidel and any director, nominee for director, executive officer or beneficial holder of more than 5% of Quidel’s outstanding common stock or any immediate family member of any of the foregoing are participants (“Interested Transactions”) to determine whether such persons have a direct or indirect material interest and whether to approve, disapprove or ratify an Interested Transaction. Quidel has written policies and procedures for monitoring and seeking approval in connection with any Interested Transaction. Quidel’s legal and finance departments assist in monitoring Interested Transactions and the Audit Committee reviews, approves (or disapproves) or ratifies Interested Transactions. In considering whether to approve or ratify an Interested Transaction, the Audit Committee takes into account, among other factors it deems appropriate, whether the Interested Transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar terms and conditions and the extent of the related person’s interest in the Interested Transaction. In addition, Quidel’s written policy provides that no director shall participate in any discussion or approval of an Interested Transaction for which he or she is a related party, except that the director shall provide all material information concerning the Interested Transaction to the Audit Committee.

Related Party Transactions

No director, nominee for director, executive officer or beneficial holder of more than 5% of Quidel’s outstanding common stock or any immediate family member of any of the foregoing had any material interest, direct or indirect, in any reportable transaction with Quidel or had any reportable business relationship with Quidel during the 2021 fiscal year or since the commencement of the current fiscal year.

Compensation Committee

The Compensation Committee is responsible for assisting the Quidel board of directors in discharging its responsibilities regarding the compensation of Quidel’s employees and directors. Under the Compensation Committee’s written charter, the specific duties of the Compensation Committee include, among others: reviewing and approving (or recommending to the Quidel board of directors for approval) corporate goals and objectives relevant to executive compensation; evaluating Quidel’s executive officers’ performance in light of such goals and objectives; determining (or recommending to the Quidel board of directors for determination) the compensation levels of Quidel’s executive officers based on such evaluations; administering Quidel’s incentive compensation plans, including Quidel’s equity-based incentive plans; and making recommendations to the Quidel board of directors regarding Quidel’s overall compensation structure, policies and programs and human capital management matters. The Compensation Committee also has the ability to retain, at Quidel’s expense and without further approval of the Quidel board of directors, compensation consultants and advisors that it deems necessary in the performance of its duties.

140

Compensation Committee Interlocks and Insider Participation

Mr. Michael, Dr. Buechler, Ms. Ordoñez and Dr. Polan are not current or former officers or employees of Quidel’s, and none has engaged in any transaction that would be required to be disclosed in this joint proxy statement/prospectus by Item 404 of Regulation S-K. There is no relationship that requires disclosure as a compensation committee interlock for purposes of Item 407(e)(4) of Regulation S-K.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee is responsible for assisting the Quidel board of directors in identifying qualified candidates for election to the Quidel board of directors; recommending the composition of Quidel board of directors and its committees; monitoring and assessing the effectiveness of the Quidel board of directors and its committees; and performing a leadership role in shaping and monitoring Quidel’s corporate governance, environmental and sustainability policies and initiatives. Under the Nominating and Corporate Governance Committee’s written charter, the specific duties of the Nominating and Corporate Governance Committee include, among others: identifying, reviewing and recruiting candidates for election to the Quidel board of directors; reviewing the qualifications of director candidates recommended by Quidel’s stockholders; monitoring the independence of current directors and nominees; recommending to the Quidel board of directors candidates for election or re-election to the Quidel board of directors at each annual meeting of stockholders; overseeing the periodic evaluation of the Quidel board of directors, its committees and each of Quidel’s incumbent directors; reviewing the Quidel board of directors succession planning; and overseeing Quidel’s Corporate Governance Guidelines, Code of Business Conduct and Ethics and sustainability strategy, initiatives and policies (including oversight of environmental management, climate risk, human rights, diversity and inclusion, stakeholder engagement and business ethics programs).

Meetings of Non-management Directors

The non-management members of the Quidel board of directors regularly meet in executive sessions without any employee director or other members of management in attendance.

Director Nominations

The Nominating and Corporate Governance Committee regularly assesses the appropriate size of the Quidel board of directors and whether any vacancies on the Quidel board of directors are expected due to retirement or otherwise. The Nominating and Corporate Governance Committee utilizes a variety of methods for identifying and evaluating director candidates. Candidates may come to the attention of the Nominating and Corporate Governance Committee through current directors, professional search firms, stockholders or other persons.

Once the Nominating and Corporate Governance Committee has identified a prospective nominee, the Nominating and Corporate Governance Committee will evaluate the prospective nominee in the context of the then-current composition of Quidel board of directors and will consider a variety of other factors, including the prospective nominee’s business, technology, medical, scientific, industry, finance and financial reporting experience and other attributes that would be expected to contribute to an effective board. As described in Quidel’s Corporate Governance Guidelines, in evaluating the suitability of individuals to serve as board members, the Quidel board of directors and the Nominating and Corporate Governance Committee consider a number of factors, including: experience at a policy-making level; strategic thinking; depth of understanding of Quidel’s industry, including relevant technology, leadership and objectivity; and a general understanding of marketing, finance and other disciplines relevant to the success of a publicly traded company and of sound principles of corporate governance in today’s business environment. The Nominating and Corporate Governance Committee seeks to identify nominees who possess a wide range of experience, skills, and areas of expertise, knowledge and business judgment. Nominees must have the attributes described above in the section titled “The Quidel Stockholders’ Meeting—Quidel Proposal No. 4—The Election of Directors Proposal—Qualifications and Characteristics for Directors” section.

The Nominating and Corporate Governance Committee will consider stockholder recommendations for director candidates. A stockholder may propose a person for consideration by the committee by submitting the individual’s name and qualifications to Quidel’s Corporate Secretary, Quidel Corporation, 9975 Summers Ridge Road, San Diego, California 92121. The Nominating and Corporate Governance Committee will consider each stockholder-recommended candidate in the same manner and under the same criteria used to evaluate all other candidates (as described above). The Quidel board of directors and the Nominating and Corporate Governance Committee evaluate each individual in the context of the Quidel board of directors functions as a whole and in light of the then-current needs of the Quidel board of directors, with the objective of providing independent, diversified and effective representation of the interests of Quidel’s stockholders.

141

Stockholders who wish to nominate candidates for election to the Quidel board of directors at any annual meeting must follow the procedures set forth in Quidel’s bylaws, including providing timely written notice, in proper form, of the intent to make such a nomination.

Communications with the Quidel Board of Directors

Quidel’s stockholders may communicate with the Quidel board of directors, a committee of the the Quidel board of directors or an individual director by sending a letter addressed to the board of directors, a committee or a director, c/o Corporate Secretary, Quidel Corporation, 9975 Summers Ridge Road, San Diego, California 92121. All communications will be compiled by Quidel’s Corporate Secretary and forwarded to the Quidel board of directors, the committee or the director accordingly.

Director Independence

The Quidel board of directors has determined that each of its directors, with the exception of Mr. Bryant, is independent within the meaning of the Nasdaq Marketplace Rules as adopted by Nasdaq, as well as with respect to enhanced independence standards contained in Nasdaq’s rules that relate specifically to audit committees and compensation committees. Mr. Bryant who serves as Quidel’s President and Chief Executive Officer is not considered to be independent because of his employment with Quidel.

Board Leadership Structure and Risk Oversight

Quidel’s Corporate Governance Guidelines provide its board with the flexibility to combine or separate the positions of Chairman of the Board and Chief Executive Officer. Quidel believes this provides the Quidel board of directors with flexibility to determine the structure that is in the best interests of Quidel across a range of situations. Historically, the Quidel board of directors has determined that the roles of Chairman and Chief Executive Officer should be separate as this structure enables Quidel’s Chairman to maintain responsibility for coordinating board activities, including the scheduling of meetings and executive sessions of the non-employee directors and managing the relevant agenda items in each case (in consultation with the Chief Executive Officer as appropriate), and Quidel’s Chief Executive Officer to focus on leading and managing Quidel. Kenneth F. Buechler, Ph.D. has served as Quidel’s Chairman of the Board since 2015. If the Quidel board of directors determines that it is preferable to combine the position of Chairman and Chief Executive Officer, the Quidel board of directors intends to designate an independent director to serve as lead independent director. The Quidel board of directors believes that its approach for overseeing risk, as described below, would be effective under a variety of leadership frameworks. Accordingly, the Quidel board of directors’ risk oversight function did not significantly impact its selection of the current leadership structure.

Quidel takes a comprehensive approach to risk management. Quidel believes risk can arise in every decision and action taken, whether strategic or operational. Quidel, therefore, seeks to include risk management principles in all of its management processes and in the responsibilities of its employees at every level. Quidel’s comprehensive approach is reflected in the reporting processes by which its management provides timely and comprehensive information to the Quidel board of directors to support the Quidel board of directors’ role in oversight, approval and decision-making.

The Quidel board of directors closely monitors the information it receives from the management and provides oversight and guidance to the management team concerning the assessment and management of risk. The Quidel board of directors approves Quidel’s high-level operating objectives, goals, strategies and policies to set the tone and direction for appropriate risk taking within the business. The Quidel board of directors and its committees then emphasize this tone and direction in their oversight of management’s implementation of Quidel’s operating objectives, goals, strategies and policies.

Quidel’s senior executives provide the Quidel board of directors and its committees with regular updates about Quidel’s strategies and objectives and the risks inherent within them at the Quidel board of directors and committee meetings and in regular reports. The board and committee meetings also provide a venue for directors to discuss issues with management. The Quidel board of directors and its committees call special meetings when necessary to address specific issues or take specific actions. In addition, Quidel’s directors have access to the management at all levels to discuss any matters of interest, including those related to risk. Those members of management most knowledgeable about the issues often attend Quidel’s board meetings to provide additional insight into items being discussed, including risk exposures.

142

The Quidel board of directors has delegated oversight of matters involving certain specific areas of risk exposure to its three standing committees. Each committee generally reports to the Quidel board of directors at regularly scheduled board meetings, and more frequently if appropriate, with respect to matters and risks for which such committee provides oversight. The specific responsibilities of each of Quidel’s board committees are more fully described above in the “—Audit Committee,” “—Compensation Committee” and “—Nominating and Corporate Governance Committee” sections.

Director Compensation

The current compensation and benefit program for Quidel’s non-employee directors is designed to achieve the following goals: compensation should fairly pay directors for work required for a company of Quidel’s size and scope; compensation should align directors’ interests with the long-term interests of Quidel’s other stockholders; and the structure of the compensation should be simple, transparent and easy for stockholders to understand. The table below relating to non-employee directors’ compensation includes the following compensation elements.

Annual Cash Retainers

The Chairman of the Quidel board of directors currently receives an annual cash retainer of $92,400. Each of the other non-employee directors receives an annual cash retainer of $50,000.

The Chair of Quidel’s Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee receives an additional annual cash retainer of $20,000, $15,000 and $10,000, respectively.

144

Non-employee Director Deferred Compensation Program

In December 2010, the Quidel board of directors adopted a non-employee director deferred compensation program that began in 2011. Participating directors may elect on a yearly basis (for the yearly period between Quidel’s annual meetings of stockholders) to receive 50% or 100% of the cash value of the director’s (i) annual retainer fee and (ii) compensation for service as a Chair of any of the Quidel board of directors’ standing committees (collectively, the “Covered Fees”) in the form of fully vested RSUs, plus an additional premium on such percentage of the Covered Fees, in the form of additional RSUs, which are subject to a one-year vesting requirement (the “Director Premium RSUs”). The additional premium applicable to the Director Premium RSUs shall be determined based on the length of time of the deferral period (between the grant date and the date the shares of common stock underlying the RSUs are to be issued) selected by the participating director as follows: (i) if one (1) year from the grant date, a premium of 10% on the amount of the Covered Fees deferred; (ii) if two (2) years from the grant date, a premium of 20% on the amount of the Covered Fees deferred; or (iii) if four (4) years from the grant date, a premium of 30% on the amount of the Covered Fees deferred. The RSUs are currently granted under the 2018 Plan (or applicable successor plan) as of the date of the applicable annual meeting of stockholders, and the number of shares awarded as RSUs is calculated based on the closing price of Quidel’s common stock on the date of the applicable annual meeting.

The table below sets forth the amount deferred, deferral period and amount of Covered Fees RSUs (as defined below) and Director Premium RSUs granted to each non-employee director for 2021.

Periodic Equity Awards

The Quidel board of directors periodically assesses potential equity awards to non-employee directors. On May 18, 2021, the Quidel board of directors approved RSU grants with a total valuation of $190,000 for each non-employee director. Accordingly, a grant of 1,624 RSUs (with a fair value per RSU based on the closing price of Quidel’s common stock on the grant date) was made to each non-employee director. The RSUs vest upon the first anniversary of the grant date.

Mr. Wilkins was appointed to the Quidel board of directors in February 2021. As part of Mr. Wilkins’s appointment to the Quidel board of directors, the Quidel board of directors approved a RSU grant with a total valuation of approximately $47,500. Accordingly, a grant was made to Mr. Wilkins of 289 RSUs (with a fair value per RSU based on the closing price of Quidel’s common stock on the grant date), which vested on May 12, 2021.

Director Stock Ownership Guidelines

The Quidel board of directors believes that each director should have a meaningful equity investment in Quidel. Quidel’s director stock ownership guidelines were revised in November 2020 to increase the stock ownership threshold for non-employee directors to five times their respective annual cash retainer. Directors are expected to satisfy and maintain this stock ownership threshold within five years of joining the Quidel board of directors. All of Quidel’s directors meet these stock ownership guidelines or are in compliance with the guidelines by retaining equity awards until compliance is reached.

Executive Compensation

Compensation Discussion and Analysis

Throughout this section of this joint proxy statement/prospectus, the individuals who served as Quidel’s CEO and Chief Financial Officer (“CFO”) during fiscal year 2021, as well as the other individuals listed in the Summary Compensation Table below, are referred to as the “Named Executive Officers” or “NEOs.” For 2021, Quidel’s NEOs are as follows: Douglas C. Bryant, President and CEO; Randall J. Steward, Chief Financial Officer; Robert J. Bujarski, Chief Operating Officer; Michelle A. Hodges, SVP, General Counsel; and Werner Kroll, SVP, Research and Development.

Executive Summary

Quidel entered 2021 with considerable momentum and experienced another transformational year. Quidel opened new channels, shipped a record number of critical products to detect COVID-19 infections, launched its Savanna MDx instrumented system in select ex-U.S. markets, and overcame obstacles and seized opportunities to broaden the range of patients, partners and providers Quidel serves and established a foundation for the future, while continuing to deliver existing products to customers around the world. Among the many outstanding performance achievements during 2021 were:

| • |  | Total revenue for 2021 increased to $1,698.6 million, a 2% increase from $1,661.7 million in 2020;

| • |  | Revenue for COVID-19 products in 2021 increased 42% to $1,267.0 million, from $891.0 million in 2020;

| • |  | Reported GAAP EPS of $16.43 per diluted share in 2021, compared to $18.60 per diluted share in 2020;

| • |  | Entered retail and at-home testing markets with QuickVue At-Home OTC COVID-19 test by creating partnerships with CVS, Walgreens, McKesson, and National Institutes of Health (“NIH”);

| • |  | Secured 12-month agreement with U.S. government expected to be worth over $500 million to supply QuickVue At-Home OTC COVID-19 tests;

| • |  | Resolved ongoing litigation with Beckman Coulter, Inc. (“Beckman”); substantially completed transition of the BNP business to Beckman in connection with which Quidel will receive cash payments of between $70.0 million and $75.0 million per year from 2022 through 2029;

| • |  | Opened new highly automated QuickVue manufacturing facility in Carlsbad, California; and

| • |  | Signed definitive agreement to acquire Ortho, to be funded through a combination of cash and newly issued debt of the combined company.

Quidel believes that the compensation to Quidel’s NEOs, including certain special compensation awards granted during 2021 in recognition of outstanding performance during the year, aligned well with both Quidel’s performance in 2021 and the objectives of Quidel’s executive compensation policies.

146

Overview and Philosophy

Despite the continued COVID-19 demands and transformational changes to Quidel in 2021, the core objectives of Quidel’s compensation program continued to be to (1) support Quidel’s mission, values and corporate strategies by adopting a “pay for performance” philosophy that provides incentives to Quidel’s executive officers and employees for support of these core principles; (2) align the interests of management with those of Quidel’s stockholders; and (3) attract, retain and motivate high quality executives. Towards these objectives, Quidel’s compensation program is designed with the following principles:

| • |  | Provide an opportunity for Quidel to communicate to Quidel’s executive officers and employees Quidel’s performance expectations and priorities directly through the selection of performance measures on which compensation is based, and calibrate payouts with achievement of those performance measures;

| • |  | Align pay such that management shares in value created from their efforts, and Quidel’s compensation expense is correlated to its profitability and stockholder returns;

| • |  | Balance rewards appropriately between efforts and results;

| • |  | Offer a competitive total compensation opportunity; and

| • |  | Have a significant portion of total compensation paid to Quidel’s executive officers in equity and dependent upon the achievement of performance goals of Quidel.

Quidel’s compensation program focuses on both short and long-term results and is composed of three key elements: (1) base salaries, which reflect individual positions and responsibilities; (2) annual cash incentive opportunities, which are a function of the short-term performance of Quidel; and (3) longer-term stock-based incentive opportunities under Quidel’s equity incentive plans, generally in the form of stock options or restricted stock unit (“RSU”) grants, which link the interests of senior management with Quidel’s other stockholders. Each of Quidel’s compensation elements is designed to simultaneously fulfill one or more of Quidel’s core objectives. During 2021, Quidel augmented these key compensation elements with special compensation awards made to key employees in recognition of their outstanding leadership and performance at a transformational time for Quidel. In 2022, Quidel will continue to make special compensation awards, as appropriate, to recognize outstanding performance during a period of unprecedented transformation, challenges, opportunities and change.

When setting compensation for 2022 and in determining compensation policies, the Compensation Committee continued its engagement of Compensia, Inc. (“Compensia”) to advise on Quidel’s executive compensation programs and took into account the results of the stockholder advisory vote on executive compensation that took place at the 2021 annual meeting of Quidel’s stockholders. In that vote, which was advisory and not binding, Quidel’s stockholders approved the compensation of Quidel’s named executive officers as disclosed in the proxy statement for the 2021 annual meeting of Quidel’s stockholders with over 97.5% of votes cast in favor of the compensation of Quidel’s named executive officers. The Compensation Committee considered the advice of Compensia and continued to apply the same general compensation principles and philosophy, while making some adjustments to Quidel’s compensation programs in connection with success, integration and retention matters in connection with the pending Ortho business combination. Quidel currently holds annual advisory votes on executive compensation.

Administration

The Compensation Committee of the Quidel board of directors administers Quidel’s executive compensation programs and approves (or recommends to the Quidel board of directors for approval) salaries of all executive officers, including those of the NEOs named in the Summary Compensation Table. The Compensation Committee is responsible for reporting to the Quidel board of directors and administering all other elements of executive compensation, including annual cash incentive and equity awards.

Compensation Plan Design and Key Elements Used to Achieve Compensation Objectives

The cash components of salary and annual incentive bonus are targeted to be moderate, yet competitive in relation to salaries and annual incentive bonuses paid to officers in similar positions in comparable companies.

Quidel’s 2021 long-term equity incentive programs for Quidel’s CEO included incentive stock-based awards in the form of non-qualified stock options, time-based RSUs and performance-based RSUs and for other NEOs included incentive stock-based awards in the form of non-qualified stock options and/or time-based RSUs. The vesting for both the non-qualified

147

stock options and the time-based RSUs for typical annual equity awards is over a four-year period, with 25% vesting each year on the anniversary of the grant date, with certain exceptions. Mr. Steward and Dr. Kroll received awards pursuant to the specific terms of their respective individual retirement programs, comprised entirely of time-based RSUs that vest over a three-year period, with one-third vesting each year on the anniversary of the grant date. The vesting for the performance-based RSUs for Mr. Bryant is over a five-year period and is tied to the achievement of net revenue growth targets over any three consecutive fiscal year period starting with the three-year period ending in 2023.

The Compensation Committee engaged Compensia to conduct a review of the competitiveness of Quidel’s executive compensation programs in 2021 in connection with determining Quidel’s 2022 executive compensation program, separate from the pending business combination with Ortho. Quidel’s executive compensation program design builds on the analysis and direction of Compensia, taking into account data from the annual Radford Global Life Sciences Survey (the “Radford Survey”) and incorporates review of comparative groups of publicly traded companies with similar revenue and employee population profiles. The Radford Survey provides data from participating companies with respect to their compensation practices in numerous areas and with respect to various positions, including senior management positions. Based on the assessment by Compensia and the Compensation Committee, the 2021 peer group was used for Quidel’s 2022 compensation assessment and did not assume that the business combination with Ortho was completed. For both 2021 and 2022, the following peer group companies were used for compensation comparisons:

2021 and 2022 Peer Group:

Align Technology, Inc. |  | Integra LifeSciencies Holdings Corporation
CONMED Corporation |  | Masimo Corporation
Emergent BioSolutions, Inc. |  | Merit Medical Systems, Inc.
Envista Holdings Corporation |  | NuVasive, Inc.
EXACT Sciences Corporation |  | ResMed, Inc.
Haemonetics Corporation |  | Teleflex, Inc.
Hill-Rom Holdings, Inc. (through acquisition in 2021) |  | Cooper Companies, Inc.
Hologic, Inc. |  | Varian Medical Systems, Inc. (through acquisition in 2021)
ICU Medical, Inc. |  | Waters Corporation
IDEXX Laboratories, Inc. |  | West Pharmaceutical Services, Inc.
Insulet Corporation |  |

Should the business combination with Ortho be completed, Quidel’s Compensation Committee, with the assistance of Compensia, will modify this peer group, as needed, to take into account the much larger size of the combined entity and plans to adjust executive compensation if appropriate.

Quidel’s Compensation Committee utilizes management and independent compensation consultants (such as Compensia in each year since 2018) to gather market data and provide analyses of Quidel’s peers’ compensation programs. The Compensation Committee does not have a philosophy of setting compensation based on specific formulaic benchmarking comparisons, but it does take into account the guidance of compensation consultants and reviews peer group data and the Radford Survey data in setting moderate, yet competitive compensation.

Since 2017, Quidel’s Compensation Committee has continued to more evenly allocate the equity incentive awards between stock options and RSUs, with 50% of the number of shares awarded in the form of non-qualified stock options and 50% of the number of shares awarded in the form of RSUs, with the recent exception of certain NEOs subject to individual retirement programs as the Compensation Committee deemed appropriate. In addition, Quidel’s Compensation Committee determined it would be in the interest of stockholders to eliminate performance-based RSUs for all executive officers other than the CEO in 2021 to better align with peer group practices.

Base Salary

Base salaries are reviewed annually and are targeted to be moderate, yet competitive in relation to salaries paid to officers in similar positions in comparable companies. With the exception of the CEO, whose performance is reviewed directly by the Quidel board of directors, performance of all other executive officers is reviewed through regular conversations on goals and achievement with the CEO in consultation with the Compensation Committee (and/or the Quidel board of directors).

148

In 2021, in connection with the setting of the base salaries of Quidel’s executive officers, the Compensation Committee considered peer group analysis and also examined survey data for executives with similar responsibilities in comparable companies in the medical device/diagnostics and biotechnology industries, using analysis performed by Compensia and referring to a custom report prepared by Compensia from data contained in the 2021 Radford Survey based on companies with a similar number of employees compared to Quidel. The base salaries of each of Quidel’s executive officers were set taking into account comparable data for salaries relevant for their positions, and then modified to further take into account Quidel’s executive officers’ experience and skills.

Annual Cash Incentive Awards

Quidel’s annual cash incentive program provides the potential for receipt of competitive levels of annual incentive cash compensation and is designed to reward senior management for their contributions to Quidel’s annual corporate objectives. Under Quidel’s annual cash incentive program, each participating officer is entitled to receive a cash bonus based on achievement of certain corporate goals in the particular fiscal year. Goals and payouts are calibrated to strike the appropriate balance between being reasonably achievable, and thereby motivating executives, while targeting improved performance. The balance is intended to result in Quidel receiving an appropriate return on its annual incentive investment. The corporate performance goals are selected to require sustained performance and results from senior management. Each eligible executive’s potential annual award under the annual cash incentive program is expressed as a percentage of base salary as of the end of the fiscal year.

In February 2021, the Compensation Committee approved the 2021 Executive Incentive Compensation Plan (the “2021 Cash Incentive Plan”), subject to ongoing review throughout the year based on fluctuating demand and expectations in connection with the COVID-19 impact on Quidel’s business. Consistent with the 2020 Cash Incentive Plan, the Compensation Committee determined it was appropriate to continue to use a limited set of key components. Similar to prior plans, the 2021 Cash Incentive Plan was designed to encourage improved performance in objectives and to improve long-term performance and results for Quidel and its stockholders.

The target bonus for the 2021 Cash Incentive Plan was initially set at 100% of annual base salary for Quidel’s CEO and 75% of annual base salary for other executive officers and provided for a maximum bonus of 140% of annual base salary for Quidel’s CEO and 105% of annual base salary for Quidel’s other executive officers.

The 2021 Cash Incentive Plan consisted of the following two components: (1) revenue performance; and (2) EBITDA targets. Each component of the 2021 Cash Incentive Plan includes targets at minimum, plan/target and maximum payout. The minimum targets serve as the threshold level of performance upon which the incentive pool would begin to fund for that component. Achievement of the components at plan/target will earn the target cash incentive opportunity. Payouts are calculated along a linear continuum from minimum to plan/target and from plan/target to maximum with the maximum target serving as the point at which the management team will earn the highest possible cash incentive opportunity. The minimum target must be met in order for a portion of the bonus to be paid relative to any one of the two components and each component is measured separately. The Compensation Committee may adjust the targets to take into account acquisitions and divestitures (so that management is not rewarded or penalized for factors outside management’s control) and retains the right to exercise discretion in modifying amounts awarded to take into account significant events that were not contemplated under the plan.

At the time the 2021 Cash Incentive Plan was initially reviewed and approved in early 2021, Quidel’s operations and size had changed dramatically since the onset of the COVID-19 pandemic in March of 2020. Throughout 2020 and continuing throughout 2021, demand for COVID-19 testing in general, and for Quidel’s COVID-19 products specifically, fluctuated significantly month-to-month and quarter-to-quarter in response to vaccine rollouts, decreasing infection and death rates, and subsequent surges resulting from variants such as Delta and Omicron. This made forecasting volume and pricing of Quidel’s COVID-19 products difficult, which resulted in a corresponding challenge in forecasting Quidel’s revenue, EBITDA and other financial metrics. At the time the 2021 Cash Incentive Plan was initially approved, the macro environment suggested an extreme demand for COVID-19 testing at higher prices. As vaccine rollouts continued and infection and death rates declined significantly moving into the summer of 2021, the demand for COVID-19 tests as well as the pricing for tests declined significantly, making it clear that the market assumptions for the 2021 Cash Incentive Plan were not likely to be realized and accordingly the metrics under the initially approved 2021 Cash Incentive Plan would not be achievable, but Quidel was performing well and meeting significant milestone and performance targets that deserved to be rewarded and incented. In response, the Compensation Committee determined in early September 2021 that the revenue and EBITDA targets for the

149

2021 Cash Incentive Plan were not realistic. The Compensation Committee further determined that it needed to continue to provide incentives for its senior management team, especially considering the extremely challenging environment Quidel was experiencing in ramping up its COVID-19 test production and the intense competition for qualified human resources in the economy in general. Accordingly, in September 2021, the Compensation Committee established a modified 2021 Cash Incentive Plan that included a 2021 EBITDA target of at least $500 million; certain Savanna launch targets by the end of the year; certain transition targets in connection with the Beckman transition agreement; and certain over-the-counter COVID-19 manufacturing milestones and Quidel home testing app development milestones. As part of this adjustment, however, the Compensation Committee further determined to reduce the target payout percentages for senior executives by 50%, while maintaining the full percentage payout for all other employees.

The following table represents the threshold, plan/target and maximum bonus for each of the NEOs as a percentage of such NEO’s annual base salary under the 2021 Cash Incentive Plan, as adjusted in September 2021.

Executive Officer |  | Threshold |  |  | Plan/Target |  |  | Maximum |
Douglas C. Bryant President and CEO |  |  | 5.0 | % |  |  | 50.0 | % |  |  | 62.5 | %
Randall J. Steward Chief Financial Officer |  |  | 3.8 | % |  |  | 37.5 | % |  |  | 46.9 | %
Robert J. Bujarski Chief Operating Officer |  |  | 3.8 | % |  |  | 37.5 | % |  |  | 46.9 | %
Michelle A. Hodges SVP, General Counsel |  |  | 3.8 | % |  |  | 37.5 | % |  |  | 46.9 | %
Werner Kroll, Ph.D. SVP, Research and Development |  |  | 3.8 | % |  |  | 37.5 | % |  |  | 46.9 | %

For the 2021 Cash Incentive Plan, as modified, bonus payouts to Quidel’s executive officers for 2021 were based on achievement at 125% of target and paid out at 50% under the revised plan: 50% based on Quidel’s achievement of EBITDA goals (actual results of $995 million or 199% of $500 million target); 20% based on achievement of Savanna launch targets; 10% based on achievement of Beckman transition targets; 10% based on achievement of over-the-counter COVID-19 manufacturing targets; and 10% based on achievement of Quidel home testing app development targets.

Annual Cash Incentive Awards

On January 31, 2022, the Compensation Committee approved payouts to executive officers for achievement of all goals under the revised 2021 Cash Incentive Plan at 62.5% of base salary for the CEO and 46.9% of base salary for the other NEOs. These payout amounts were based on achievement of (i) EBITDA performance at the maximum level and (ii) full achievement of all other milestone targets. The bonuses earned by Mr. Bryant, Mr. Steward, Mr. Bujarski, Ms. Hodges and Dr. Kroll were $547,188, $234,164, $246,094, $210,938 and $257,813, respectively.

Deferred Bonus Program

Each of the above NEOs is eligible to elect to participate in Quidel’s Employee Deferred Bonus Compensation Program (the “Employee Deferred Program”) with respect to any payments received under the 2021 Cash Incentive Plan, 2022 Cash Incentive Plan (as defined below) and future cash incentive plans. Under the Employee Deferred Program, participating officers could elect to receive 50% or 100% of the cash value of his or her annual cash incentive bonus (the “Covered Bonus”) (payable (if applicable) per the terms and conditions of the 2021 and 2022 Cash Incentive Plans) in the form of fully vested RSUs (the “Converted RSUs”), plus an additional premium on such percentage of the Covered Bonus in the form of additional RSUs, which are subject to a one-year vesting requirement (the “Premium RSUs”). The additional premium applicable to the Premium RSUs will be determined based on the length of time of the deferral period (between the grant date and the date the shares of common stock underlying the Converted RSUs are to be issued) selected by the participating officer as follows: (i) if one (1) year from the grant date, a premium of 10% on the amount deferred of the Covered Bonus; (ii) if two (2) years from the grant date, a premium of 20% on the amount deferred of the Covered Bonus; or (iii) if four (4) years from the grant date, a premium of 30% on the amount deferred of the Covered Bonus.

Elections for the Employee Deferred Program for 2021 and 2022, which are irrevocable, were made by the following NEOs:

|  |  | 2021 |  |  |  | 2022 |
Executive Officer |  | Amount Deferred |  |  | Deferral Period |  |  | Amount Deferred |  |  | Deferral Period |
Douglas C. Bryant President and CEO |  |  | 50 | % |  |  | 4 years |  |  |  | 100 | % |  |  | 4 years |
Randall J. Steward Chief Financial Officer |  |  | 50 | % |  |  | 2 years |  |  |  | — |  |  |  | — |
Robert J. Bujarski Chief Operating Officer |  |  | 50 | % |  |  | 4 years |  |  |  | — |  |  |  | — |
Michelle A. Hodges SVP, General Counsel |  |  | 50 | % |  |  | 2 years |  |  |  | — |  |  |  | — |
Werner Kroll, Ph.D. SVP, Research and Development |  |  | — |  |  |  | — |  |  |  | — |  |  |  | — |

The Converted RSUs will be fully vested on the grant date. The Premium RSUs will be fully vested on the first anniversary of the grant date. Subject to the terms and conditions in the grant award agreement, the shares of common stock underlying Converted RSUs will be issued as soon as administratively practicable after the earliest of: (1) the end of the deferral period selected by the participating officer; (2) the participating officer’s separation from Quidel; and (3) a change in the ownership or effective control of Quidel, or in the ownership of a substantial portion of the assets of Quidel (a “Change in Control”). The shares of common stock underlying the Premium RSUs will have the same applicable issuance periods as outlined in the foregoing sentence for Converted RSUs with acceleration of the one-year vesting requirement in connection with a Change in Control; provided, however, that if a participating officer’s service is terminated for any reason (outside of a Change in Control) prior to the one-year vesting requirement, the Premium RSUs shall be forfeited and canceled as of the date of such termination of service.

Longer-Term Equity Incentive Awards

Longer-term equity-based incentive awards in the form of stock options and/or RSUs are intended to align the interests of management with those of Quidel’s other stockholders and promote retention of Quidel’s executives by using continued service, and in the case of certain awards, the achievement of specified performance levels, as a requirement to receive the value of the awards. The number of stock options and/or shares of RSUs granted is related to the individual’s level of responsibility and allows executives to share in the value they help create. Generally, the Compensation Committee does not consider an executive’s stock holdings or outstanding equity awards in determining the number of equity awards to be granted; however, the Compensation Committee does take into consideration the total number of outstanding shares of Quidel’s common stock, the relative dilution to stockholders, as well as Quidel’s gross equity burn rate, issued equity overhang and total equity overhang in determining the number of equity awards to be granted. The Compensation Committee believes that Quidel’s executive officers should be fairly compensated each year relative to market pay levels of Quidel’s peer group. The Compensation Committee views longer-term equity incentives as a primary compensation means for retaining executives.

Quidel’s 2021 long-term equity incentive program for Quidel’s CEO included incentive stock-based awards in the form of non-qualified stock options, time-based RSUs and performance-based RSUs and for Mr. Bujarski and Ms. Hodges included incentive stock-based awards in the form of both non-qualified stock options and time-based RSUs. The vesting for the non-qualified stock options is over a four-year period, with 25% vesting each year on the anniversary of the grant date. The stock options have an exercise price equal to the closing price of Quidel’s common stock on the grant date. Consistent with 2020, the Compensation Committee determined to weight the number of shares awarded for long-term incentive awards between stock options and RSUs, which the Compensation Committee believed was in alignment with peer group practices. In 2021, for Mr. Bujarski and Ms. Hodges, 50% of the equity incentive award shares were provided in the form of non-qualified stock options and 50% of the equity award shares were provided in the form of RSUs. For the CEO, the number of RSUs were divided equally between time-vested RSUs and performance-based RSUs. For Mr. Bujarski and Ms. Hodges, the vesting for the time-based RSUs is over a four-year period, with 25% vesting each year on the anniversary of the grant date. The vesting for the performance-based RSUs granted to the CEO is over a five-year period and is tied to the achievement of net revenue growth targets, as adjusted for the financial impact of merger, acquisition and divestiture activities. The amounts of the awards were determined based on the executive compensation analysis and review performed

151

by Compensia, which takes into account data from the Radford Survey and peer group compensation practices, as discussed in the “—Compensation Plan Design and Key Elements Used to Achieve Compensation Objectives” section above. The awards for Mr. Steward and Dr. Kroll were comprised entirely of time-based RSUs that vest over a three-year period, with one-third vesting each year on the anniversary of the grant date, pursuant to the terms of each executive’s individual retirement program. See the “—Employment, Change in Control and Severance Arrangements” section.

In 2021, Mr. Bryant, Mr. Steward, Mr. Bujarski, Ms. Hodges and Dr. Kroll were awarded non-qualified stock options, time-based RSUs, and performance-based RSUs, as follows:

2022 Compensation Actions

In January 2022, the Compensation Committee approved Quidel’s 2022 cash incentive plan for the initial six-month period of Quidel’s fiscal year ending December 31, 2022 (the “2022 Cash Incentive Plan”). Payout under the 2022 Cash Incentive Plan is predicated upon achievement of (i) revenue targets and (ii) EBITDA targets, with each of the foregoing as determined by the Quidel board of directors and/or the Compensation Committee, for the initial six-month period of Quidel’s 2022 fiscal year, based on the assumption that the second-half targets would be established after the anticipated closing of the Ortho business combination. The following table represents the threshold, plan/target and maximum bonus for each of the NEOs as a percentage of such NEO’s annual base salary under the 2022 Cash Incentive Plan.

Executive Officer |  | Threshold |  |  | Plan/Target |  |  | Maximum |
Douglas C. Bryant |  |  | 62.5 | % |  |  | 125 | % |  |  | 175 | %
President and CEO |  |  |  |  |  |  |  |  |  |  |  |
Randall J. Steward |  |  | 37.5 | % |  |  | 75 | % |  |  | 105 | %
Chief Financial Officer |  |  |  |  |  |  |  |  |  |  |  |
Robert J. Bujarski |  |  | 50.0 | % |  |  | 100 | % |  |  | 140 | %
Chief Operating Officer |  |  |  |  |  |  |  |  |  |  |  |
Michelle A. Hodges |  |  | 37.5 | % |  |  | 75 | % |  |  | 105 | %
SVP, General Counsel |  |  |  |  |  |  |  |  |  |  |  |
Werner Kroll, Ph.D. |  |  | 37.5 | % |  |  | 75 | % |  |  | 105 | %
SVP, Research and Development |  |  |  |  |  |  |  |  |  |  |  |

For the 2022 Cash Incentive Plan, bonus payouts to Quidel’s executive officers will be based 60% on achievement of revenue performance and 40% on EBITDA goals.

Also in January 2022, the Compensation Committee approved Quidel’s 2022 long-term equity incentive program. Under the 2022 equity incentive program, each NEO receives equity incentive awards in the form of (i) time-based RSUs and/or (ii) non-qualified stock options as follows:

Executive Officer |  | Time-Based Restricted Stock Units (# shares) |  |  | Non-Qualified Stock Options (# shares) |
Douglas C. Bryant President and CEO |  |  | 27,043 |  |  |  | 27,043 |
Randall J. Steward Chief Financial Officer |  |  | 14,512 |  |  |  | — |
Robert J. Bujarski Chief Operating Officer |  |  | 12,878 |  |  |  | 12,876 |
Michelle A. Hodges SVP, General Counsel |  |  | 6,439 |  |  |  | 6,438 |
Werner Kroll, Ph.D. SVP, Research and Development |  |  | 10,642 |  |  |  | — |

The vesting periods for the non-qualified stock options and time-based RSUs, with the exception of awards to Mr. Steward and Dr. Kroll, are each over a four-year period, with 25% vesting each year on the anniversary of the grant date. The awards to Mr. Steward and Dr. Kroll in 2022 are comprised entirely of time-based RSUs that vest over a three-year period, with one-third vesting each year on the anniversary of the grant date, pursuant to the terms of such executive’s individual retirement program.

On January 31, 2022, in connection with the anticipated closing of the Ortho business combination, the Compensation Committee also approved the grant of (i) success bonus awards for each of Mr. Bryant, Mr. Steward, Mr. Bujarski and Ms. Hodges in the following amounts: Mr. Bryant: $875,500; Mr. Steward: $499,550; Mr. Bujarski: $525,000; and Ms. Hodges: $450,000; (ii) integration/retention cash bonus awards for each of Mr. Bryant, Mr. Steward, Mr. Bujarski, Ms. Hodges and Dr. Kroll in the following amounts: Mr. Bryant: $717,500; Mr. Steward: $349,685; Mr. Bujarski: $420,000;

153

Ms. Hodges: $315,000; and Dr. Kroll: $385,000; and (iii) integration/retention equity awards for each of Mr. Bryant, Mr. Bujarski, Ms. Hodges and Dr. Kroll in the following amounts: Mr. Bryant: $2,500,000; Mr. Bujarski: $1,400,000; Ms. Hodges: $750,000; and Dr. Kroll: $750,000. The success bonus awards will be grossed up for taxes and become payable upon the closing of the Ortho business combination. The first 25% of the integration/retention cash bonus awards will become payable upon the closing of the Ortho business combination, and the remaining 75% upon the first anniversary thereof. The integration/retention equity awards were granted in the form of RSUs and will vest with respect to 50% of the award on the second anniversary of the grant date and the remaining 50% in equal annual installments (25% per year) thereafter; provided, however, that (x) the vesting of the RSUs is contingent upon the consummation of the Ortho business combination having occurred prior to the applicable vesting date, and (y) the RSUs will be automatically forfeited in the event the agreement governing the Ortho business combination transaction is terminated in accordance with its terms.

Equity Ownership Guidelines

To further align the interests of Quidel’s directors and executives with those of Quidel’s other stockholders, the Quidel board of directors has adopted stock ownership guidelines and increased ownership requirements for Quidel’s CEO and directors in 2020. Under these guidelines, each non-employee director, the CEO, each Senior Vice President and each Vice President is required to retain and hold 50% of the shares acquired under any equity incentive award granted on or after March 19, 2004 (after subtracting shares sold to pay for option exercise costs and relevant federal and state taxes, which are assumed to be at the highest marginal tax rates). The foregoing stock retention rule applies unless such director or officer beneficially owns shares with a value at or in excess of the following stock ownership guidelines:

| • |  | CEO — 6 times then-current annual base salary,

| • |  | Section 16 Officers — 2 times then-current annual base salary,

| • |  | Non-Section 16 Officer Senior Vice Presidents and Vice Presidents — 1 times then-current annual base salary, and

| • |  | Non-employee Directors — 5 times then-current annual cash retainer.

The value of an individual’s shares for purposes of the stock ownership guidelines is deemed to be the greater of the then-current fair market value of the stock, or the individual’s cost basis in the stock. Shares counted in calculating the stock ownership guidelines include shares beneficially owned outright, whether from open market purchases, purchases through Quidel’s ESPP, shares retained after option exercises, and shares received pursuant to RSU awards once the awards covering such shares have vested. In addition, in the case of vested, unexercised, in-the-money stock options, the in-the-money value of the stock options will be included in the stock ownership guidelines calculation. Also, the vested RSUs held pursuant to Quidel’s Deferred Compensation Programs are included in the stock ownership guidelines calculation. Individuals have five years from their election, hire or promotion to satisfy the stock ownership guidelines. All officers and directors meet these stock ownership guidelines or are in compliance with the guidelines by retaining equity awards until compliance is reached.

Restrictions on Trading Securities (Including Hedging and Pledging)

Quidel has an Insider Trading Policy that prohibits employees and directors from engaging in speculative transactions involving Quidel’s securities. Accordingly, hedging transactions involving Quidel’s securities are prohibited, including, but not limited to, purchase of stock on margin, short sales, buying or selling puts or calls, and any other similar transactions or arrangements that have an economic consequence of establishing downside price protection. Quidel’s Insider Trading Policy also prohibits officers and directors from pledging Quidel stock, subject to special approval from Quidel board of directors. No special approvals have been provided to allow any current officer or director to pledge Quidel stock.

Pay Recoupment (Clawback) Policy

Quidel’s Compensation Committee approved a clawback policy in February 2021 that covers annual and longer-term incentive compensation awarded or paid to Quidel’s Section 16 officers. Under this policy, if Quidel is required to restate Quidel’s financial statements due to fraud, misconduct or SEC or financial non-compliance and the amount of Quidel’s long-term incentive compensation awarded or paid would have been lower had the achievement of the applicable financial performance been calculated based on the restated financial results, Quidel’s Compensation Committee may, in its discretion, recover the amount of excess compensation awarded or paid during the three-year period preceding the date of such restatement. Quidel believes this clawback policy enhances the accountability of Quidel’s executive officers and significantly mitigates the risks associated with Quidel’s executive compensation program.

154

Employment and Severance Agreements

Quidel has entered into change in control agreements with each of Quidel’s executive officers in order to foster their objectivity in making decisions with respect to any pending or threatened change in control transaction and to alleviate certain risks and uncertainties with regard to Quidel’s executive officers’ financial and professional security that may be created by a pending or threatened change in control transaction. The details of the change in control agreements and any employment, retirement or severance arrangements entered into with Quidel’s executive officers are provided in the “—Employment, Change in Control and Severance Arrangements” section.

Tax Deductibility of Compensation

In general, Section 162(m) of the U.S. Internal Revenue Code (the “Code”) precludes publicly held corporations from deducting for U.S. federal income tax purposes in excess of $1,000,000 per year in compensation per person paid to certain executives designated as “covered employees” under Section 162(m) of the Code (generally, Quidel’s CEO, CFO and its three highest paid executive officers other than its CFO). The exemption from Section 162(m)’s deduction limit for performance-based compensation has been repealed, effective for taxable years beginning after December 31, 2017, such that compensation paid to Quidel’s covered employees in excess of $1,000,000 will not be deductible unless it qualifies for limited transition relief applicable to certain arrangements in place as of November 2, 2017. The $1,000,000 compensation limit was also expanded to apply to executives who were covered employees in years other than the then-current taxable year.

No assurance can be given that any compensation intended to satisfy the requirements for exemption from Section 162(m) as qualifying grandfathered arrangements in fact will or that compensation paid to Quidel’s executive officers who are covered by Section 162(m) intended to be deductible will be deductible in the future.

While Quidel will continue to consider the tax effect (including with respect to the expected lack of deductibility under amended Section 162(m)) of compensation decisions, the principal consideration behind Quidel’s selection of components of executive compensation continues to be whether the component can facilitate achievement of Quidel’s executive compensation program objectives. In this regard, for 2021, we have not made any changes to the basic structure of Quidel’s executive compensation program.

Stock Option and RSU Grant Practices

As described above, Quidel uses stock options as part of its overall compensation program. Stock options provide individuals with the right to purchase a specified number of shares of Quidel’s stock at a specific price. Quidel sets the exercise price of the stock options that it awards at or above the closing price of Quidel’s stock on the grant date. Accordingly, the option grant will have value to the individual only if he or she continues his/her service to Quidel during the vesting period and then generally only if and to the extent that the market price of the underlying shares of common stock appreciates over the option term.

Awards of equity-based compensation to Quidel’s executive officers, such as options and RSUs, are determined and approved by the Quidel board of directors or the Compensation Committee. Equity grants are typically made at the time of hire for executives and then annually as part of the overall executive compensation review. The specific terms of the awards are determined based on the position of the individual in the organization and as part of the applicable annual equity incentive program and takes into account relevant Compensia and Radford Survey data and peer group compensation practices, as discussed above under the “—Compensation Plan Design and Key Elements Used to Achieve Compensation Objectives” section.

For executives, new hire grants are approved by Quidel board of directors or the Compensation Committee when the executive’s hire is approved, with the actual option grant issued on the first date of employment and the exercise price of such option set at the closing price of Quidel’s common stock on that date. Annual performance grants made as part of the overall executive compensation program are generally made as of the date of approval by Quidel board of directors or Compensation Committee. This typically occurs prior to the end of the first quarter in each calendar year, with grants effective on the date of approval by Quidel board of directors or Compensation Committee and at a price at or above the closing price on the grant date.

155

In addition, the Compensation Committee and Quidel board of directors believe it is appropriate to consider special compensation awards in connection with the COVID-19 pandemic and other special circumstances and may continue to make special compensation awards, including equity-based awards, similar to 2020 and 2021, in order to incent and reward performance.

Perquisites and Other Benefits

The Compensation Committee believes that the NEOs should participate in the same benefit programs as Quidel’s other employees and that special executive perquisites should be minimal. Consistent with this philosophy, the NEOs participate in Quidel’s employee benefit plans on the same terms as other employees. These plans include medical and dental insurance, disability coverage, life insurance, the ESPP and the 401(k) plan.

Compensation of the Chief Executive Officer

Quidel’s CEO generally participates in the same executive compensation program provided to Quidel’s other executive officers and senior management as described above, except that for 2021, Quidel’s CEO received a portion of his RSUs in the form of performance-based RSUs whereas other executives only received time-based RSUs. The Compensation Committee’s approach to setting compensation for the CEO is to be competitive with comparable companies and to have a significant portion of total compensation depend upon the achievement of performance goals for Quidel.

In February 2021, the Compensation Committee approved an increase in the annual base salary for Mr. Bryant from $850,000 to $875,500. As described above, under the revised 2021 Cash Incentive Plan, the Compensation Committee approved payout at 125% of target with payout reduced by 50% per the modified plan terms, effective January 31, 2022, for combined achievement of adjusted EBITDA and other performance goals. Accordingly, Mr. Bryant earned a payout of $547,188. As discussed above under the “—Longer-Term Equity Incentive Awards” section, in 2021, Mr. Bryant was also awarded 4,462 shares of time-based RSUs, 4,462 shares of performance-based RSUs, and 8,924 shares of non-qualified stock options under the 2021 long-term equity incentive program, as well as 11,140 shares of non-qualified stock options for his efforts and contributions to the achievement of certain key milestones.

Compensation of the Other Named Executive Officers

In February 2021, the Compensation Committee approved an increase in the base salaries of Mr. Steward, Mr. Bujarski, Ms. Hodges and Dr. Kroll. Ms. Hodges’s base salary was subsequently adjusted and the base salaries were approved as follows:

Executive Officer |  | Prior Base Salary |  |  | 2021 Base Salary |
Randall J. Steward Chief Financial Officer |  | $ | 485,000 |  |  | $ | 499,550 |
Robert J. Bujarski Chief Operating Officer |  | $ | 515,000 |  |  | $ | 525,000 |
Michelle A. Hodges SVP, General Counsel |  | $ | 401,700 |  |  | $ | 450,000 |
Werner Kroll, Ph.D. SVP, Research and Development |  | $ | 407,679 |  |  | $ | 550,000 |

As described above, the Compensation Committee approved payout at the maximum level, effective January 31, 2022, under the revised 2021 Cash Incentive Plan for combined achievement of EBITDA and other performance goals for these officers, and, accordingly, Mr. Steward, Mr. Bujarski, Ms. Hodges and Dr. Kroll earned a payout of $234,164, $246,094, $210,938 and $257,813, respectively.

As discussed above under the “—Longer-Term Equity Incentive Awards” section, in 2021, Mr. Bujarski and Ms. Hodges were awarded shares of time-based RSUs and non-qualified stock options and Mr. Steward and Dr. Kroll were awarded shares of time-based RSUs.

(1) | These rows show the potential value of the payout under the “Estimated Future Payouts Under Non-Equity Incentive Plan Awards” columns for each NEO under the 2021 Cash Incentive Plan, as revised, if the threshold, target, and maximum goals are satisfied for all performance measures. The business measurements, performance goals and salary and bonus multiples for determining the payout are described in the “—Compensation Discussion and Analysis”

| section. The performance measurements were achieved in fiscal year 2021 in the aggregate at the maximum level, as revised, for Mr. Bryant and the other NEOs and payouts were made as described in the “—Compensation Discussion and Analysis—Annual Cash Incentive Awards” section and in Note (4) to the Summary Compensation Table.

(2) | These columns show the potential number of awards to be paid out to Mr. Bryant related to the performance-based RSUs if the target is achieved. The performance-based RSUs for Mr. Bryant were granted on February 1, 2021 and vest over a five-year period, the vesting of which is tied to the achievement of net revenue growth targets over any three consecutive fiscal year period starting with the three-year period ending in 2023.

(3) | This column shows the number of time-based RSUs granted in 2021 to the NEOs. Time-based RSUs for Mr. Bryant, Mr. Bujarski and Ms. Hodges vest over a four-year period, with 25% vesting each year on the anniversary of the grant date. Time-based RSUs for Mr. Steward and Dr. Kroll vest over a three-year period, with one-third vesting each year on the anniversary of the grant date. This column also includes the number of RSUs granted in 2021 under the 2021 Employee Deferred Program. For the RSUs under the 2021 Employee Deferred Program, the number is equal to (i) the amount of the NEO’s bonus deferred under the program, divided by the market closing price of Quidel’s common stock on January 31, 2022, multiplied by (ii) either 1.2 or 1.3, as a premium. For Mr. Bryant, Mr. Steward, Mr. Bujarski and Ms. Hodges $273,490, $117,004, $122,998 and $105,428 (included in the “Grant Date Fair Value” column), respectively, represent compensation deferred and are included in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table.

(4) | This column shows the number of stock options granted in 2021 to the NEOs. These options vest and become exercisable over a four-year period, with 25% vesting each year on the anniversary of the grant date, except for the stock option granted to Mr. Bryant on July 28, 2021, which vests and becomes exercisable over a three-year period, with one-third vesting and becoming exercisable each year on the anniversary of the grant date.

(5) | This column shows the exercise price for the stock options granted, which was the closing price of Quidel’s common stock on the grant date.

(6) | This column shows the full grant date fair value under ASC Topic 718 of time-based RSUs, performance-based RSUs and stock options granted to the NEOs in 2021. For the time-based RSUs and performance-based RSUs, fair value is calculated using the closing price of Quidel’s common stock on the grant date. The grant date fair value is the amount that we would expense in Quidel’s Consolidated Financial Statements over the award’s vesting schedule, unless the NEO leaves Quidel. For stock options, fair value is calculated using the Black-Scholes value on the grant date and is the amount that we would expense in Quidel’s Consolidated Financial Statements over the award’s vesting schedule, unless the NEO leaves Quidel. For additional information on the valuation assumptions, refer to Note 6 of Quidel’s Consolidated Financial Statements for the year ended December 31, 2021.

Under his employment agreement, Mr. Bryant is an “at-will” employee of Quidel, which means that either Mr. Bryant or we may terminate his employment at any time for any reason. However, and except in the context of a change in control, if Mr. Bryant’s employment with us is terminated without “cause” or he terminates his employment for “good reason” (each as defined in his employment agreement) and thereafter delivers and does not revoke a general release, he is entitled to a severance payment equal to eighteen (18) months of his then-current base salary and payment of health insurance premiums for a period of eighteen (18) months following termination. Amounts payable to Mr. Bryant upon a change in control of Quidel are generally governed by his change in control agreement, dated as of January 16, 2009, which is described below.

Mr. Steward, Mr. Bujarski, Ms. Hodges and Dr. Kroll are each “at will” employees of Quidel with compensation arrangements that include, among other items: (i) a base salary for 2021 of $499,550, $525,000, $450,000 and $550,000 per annum, respectively; and (ii) eligibility for an annual cash bonus in accordance with Quidel’s Cash Incentive Plan. In addition, except in the context of a change in control, if we terminate Mr. Bujarski’s employment without cause, he would be entitled to a severance payment equal to six months of his annual salary.

163

Mr. Steward and Dr. Kroll each entered into individual retirement and retention programs with us in November 2019 and February 2020, respectively. These programs were entered into and approved by the Quidel board of directors and the Compensation Committee as part of Quidel’s succession planning and to incentivize Mr. Steward to continue employment through at least March 31, 2022 and Dr. Kroll to continue employment through at least March 31, 2023. On February 1, 2022, Quidel and Mr. Steward entered into an amendment to his individual retirement program, which extended the term of his employment beyond March 31, 2022 through the earlier of the consummation of the Ortho business combination or termination of the business combination agreement. For each calendar year that Mr. Steward continues to be employed by Quidel as its CFO, he will receive RSUs with a value on the grant date of $1,300,000 that will vest one-third each year on the anniversary of the grant date, subject to Mr. Steward’s continued employment with Quidel in any capacity. For each calendar year that Dr. Kroll continues to be employed by Quidel as its Senior Vice President, Research and Development, he will receive non-qualified stock options and/or RSUs with a value on the grant date of $1,000,000 that will vest one-third each year on the anniversary of the grant date, subject to Dr. Kroll’s continued employment with Quidel in any capacity. The programs contemplate that the RSU and/or option grants described above will constitute the sole equity incentive compensation that Mr. Steward and Dr. Kroll will be entitled to receive on or after January 1, 2020, unless Quidel determines otherwise. Dr. Kroll’s individual retirement program contemplates that if he remains employed and in good standing in his position through the target date, then upon ceasing to serve in his current role, he will enter into a special advisor agreement, in the form provided in his program, and be engaged as a full-time employee, serving as a non-officer special advisor for a period of one year at a reduced pay rate and his equity awards will continue to vest and be governed by the applicable equity incentive plan and award agreements. Mr. Steward’s individual retirement program contemplates that if he remains employed and in good standing in his position through the target date, then upon ceasing to serve in his current role, he will enter into a special advisor agreement, in the form provided in his program, and be engaged as a full-time employee, serving as a non-officer special advisor for a period of one year at a pay rate of $300,000 per year and his equity awards will continue to vest and be governed by the applicable equity incentive plan and award agreements through the one-year period following the earlier of the consummation of the Ortho business combination or termination of the business combination agreement.

Each of Mr. Bryant, Mr. Steward, Mr. Bujarski, Ms. Hodges and Dr. Kroll has entered into a change in control agreement with us, which provides for the payment of severance benefits in the event of termination of employment in connection with a change in control of Quidel. The severance benefits are payable if their respective employment with us is terminated within 30 days prior to or three years following a change in control, unless terminated for cause or the termination is the result of a voluntary resignation (which does not include resignations stemming from a material adverse change in responsibilities, status, compensation, authority or location of workplace) or their death or disability. The change in control agreement for each of Quidel’s NEOs includes a covenant by the NEO to not solicit, recruit or hire-away Quidel’s employees or solicit, influence or attempt to influence any person or entity to terminate such person’s or entity’s contractual and/or business relationship with Quidel.

The severance benefits under the change in control agreements generally consist of a lump sum cash payment equal to two times the sum of (i) such executive’s highest annual salary rate within the three-year period ending on the date of termination, plus (ii) an amount equal to the annualized average of all bonuses paid to the executive during the two-year period immediately before the date of termination. In addition, the change in control agreements provide for: payment of $25,000 to help defray the legal, tax and accounting fees and other costs associated with transitional matters; continued coverage for two years under Quidel’s group medical insurance, group dental insurance and group vision insurance programs, unless and to the extent the executive obtains concurrent coverage through another program, in which case Quidel’s coverage will be terminated or reduced as applicable; and immediate vesting and exercisability of any and all unvested stock options and RSUs held by the executive (unless previously waived or otherwise expressly agreed to by the executive).

Potential Post-employment Payments

As described above, Quidel’s NEOs have employment, severance and/or change in control agreements with us. The table below illustrates the compensation that would be payable by us to each NEO in the event of a change in control of Quidel or a termination of the NEO’s employment with Quidel for various described reasons, sometimes referred to in this section as a “triggering event.” In accordance with applicable SEC rules, the following illustrations assume:

| • |  | that the triggering event in question, the death, disability, change in control or termination occurred on December 31, 2021, which was the last full business day prior to the last day of Quidel’s 2021 fiscal year end, which fell on Sunday, January 2, 2022; and

164

| • |  | the calculations provided below are based on the closing market price of Quidel’s common stock as of December 31, 2021, which was $134.99.

In addition, in connection with any actual termination of employment, the Quidel board of directors or the Compensation Committee may determine to enter into an agreement providing additional benefits or amounts, or altering the terms of benefits described below, as deemed appropriate by the Quidel board of directors or the Compensation Committee. The illustrations exclude any vested awards deferred pursuant to Quidel’s Employee Deferred Programs. The actual amounts that would be paid upon an NEO’s termination of employment can only be determined at the time of such NEO’s separation from Quidel. Due to the number of factors that affect the nature and amount of any benefits provided upon the events discussed below, any actual amounts paid or distributed may be higher or lower than reported below. Factors that could affect these amounts include Quidel’s stock price at the time of termination and determinations by the Quidel board of directors.

(1) | Payable in one lump sum upon termination.

(2) | This amount represents the annualized average of all bonuses paid to the NEO in 2020 and 2021.

(3) | This represents the value of unvested RSUs and unearned performance-based RSUs at target levels, including Premium RSUs earned pursuant to the Employee Deferred Programs as detailed in the “Nonqualified Deferred Compensation” table.

| concurrent coverage through another program, in which case Quidel’s coverage will be terminated or reduced as applicable. In addition, if Mr. Bryant’s employment is terminated without “cause” or he terminates his employment for “good reason” (each as defined in his employment agreement) and thereafter does not revoke a general release, he is entitled to receive payment of health insurance premiums for a period of eighteen (18) months following termination.

(6) | Each NEO’s change in control agreement provides for payment of $25,000 to help defray the legal, tax and accounting fees and other costs associated with transitional matters.

CEO Pay Ratio

We are providing the following information regarding the relationship of the annual total compensation of Quidel’s CEO and that of Quidel’s “median employee,” as required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K. The pay ratio information provided below is a reasonable estimate calculated in a manner consistent with these pay ratio disclosure rules.

For Quidel’s 2021 fiscal year:

| • |  | The estimated median of the annual total compensation of all of Quidel’s employees, excluding the CEO, was $79,053;

| • |  | The annual total compensation of Quidel’s CEO, as reported in the Summary Compensation Table, was $5,546,216; and

| • |  | The ratio of the annual total compensation of Quidel’s CEO to the median of the annual total compensation of all other employees was estimated to be 70 to 1.

In determining the pay ratio information provided above, we first identified Quidel’s “median employee” for the 2021 fiscal year by using the following methodology, as permitted by the SEC’s pay ratio disclosure rules:

| • |  | We selected December 31, 2021 as the date upon which we would identify Quidel’s employee population and median employee and, from Quidel’s tax and payroll records, we compiled a list of 1,645 total full-time, part-time, temporary and seasonal employees who were employed on that date.

| • |  | We used total cash compensation during the 2021 fiscal year as a consistently applied compensation measure to identify Quidel’s median employee from the employees on the list. For this purpose, we define total cash compensation as base wages. We did not include incentive cash compensation because Quidel’s incentive cash compensation program does not extend throughout the organization and would therefore not be expected to impact the determination of the median employee.

Once Quidel’s median employee was identified in the manner described above, we calculated the annual total compensation of the median employee using the same methodology that we used to determine the annual total compensation of Quidel’s CEO, as reported in the Summary Compensation Table.

It should be noted that the SEC’s pay ratio disclosure rules provide reporting companies with flexibility in determining the methodology used to identify the median employee and the pay ratio. Accordingly, Quidel’s methodology may differ materially from the methodology used by other companies to prepare their pay ratio disclosures, which may contribute to a lack of comparability between Quidel’s pay ratio and the pay ratio reported by other companies, including those within Quidel’s industry.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires Quidel’s directors, executive officers and holders of more than 10% of Quidel Shares to file reports of their ownership and changes in ownership of Quidel Shares with the SEC. Specific due dates for these reports have been established, and Quidel is required to disclose any late filings during the year ended December 31, 2021. Based solely on Quidel’s review of the reports filed during 2021 and written representations from Quidel’s directors and executive officers that no other reports were required, all Section 16(a) filing requirements were satisfied with respect to 2021, except that one Form 4 for William J. Ferenczy, reporting two transactions, that was due on June 15, 2021 and one Form 4 for Michelle A. Hodges, reporting one transaction, that was due on May 27, 2021 were filed late on June 16, 2021.

Securities Available for Issuance under Quidel’s Equity Compensation Plans

The following table provides information with respect to Quidel’s equity compensation plans as of December 31, 2021, which plans were as follows: the 1983 ESPP; the 2001 Equity Incentive Plan; the Amended and Restated 2010 Equity

166

Incentive Plan; the 2016 Equity Incentive Plan; and the 2018 Plan. The 2001 Equity Incentive Plan, the Amended and Restated 2010 Equity Incentive Plan, and the 2016 Equity Incentive Plan have been terminated, expired or superseded by subsequent plans, and thus no additional awards will be made under such plans. However, any outstanding awards under such plans will continue to vest in accordance with their terms.

Plan Category |  | Number of Securities to be Issued upon Exercise of Outstanding Options, Warrants and Rights (a) |  |  | Weighted-average Exercise Price of Outstanding Options, Warrants and Rights (b) |  |  | Number of Securities Remaining Available for Future Issuance under Equity Compensation Plans (Excluding Securities Reflected in Column (a)) (c) |

BUSINESS OF QUIDEL AND CERTAIN INFORMATION ABOUT QUIDEL

Quidel commenced operations in 1979 and was originally incorporated as Monoclonal Antibodies, Inc. in California. In 1987, Quidel re-incorporated as Quidel Corporation in the State of Delaware. Quidel’s executive offices are located at 9975 Summers Ridge Road, San Diego, California 92121, and its telephone number is (858) 552-1100. Additional information about Quidel and its subsidiaries is included in documents incorporated by reference into this joint proxy statement/prospectus. See the section entitled “Where You Can Find More Information” of this joint proxy statement/prospectus.

Overview of Business

Quidel’s primary mission is to advance diagnostics to improve human health. Quidel has a leadership position in the development, manufacturing and marketing of rapid diagnostic testing solutions. Quidel separates these into four product categories: rapid immunoassay, cardiometabolic immunoassay, molecular diagnostic solutions and specialized diagnostic solutions. Quidel currently sells its products directly to end users and distributors, in each case, for professional use in physician offices, hospitals, clinical laboratories, reference laboratories, urgent care clinics, leading universities, retail clinics, pharmacies and wellness screening centers, as well as for individual, non-professional, OTC use. More recently, Quidel has begun to reach significant new markets as it introduced its QuickVue® At-Home OTC COVID-19 test for reopening schools, and for health departments, employers, entertainment centers and many other locations. Quidel markets its products through a network of distributors and a direct sales force. Quidel operates in one business segment that develops, manufactures and markets its products globally.

Quidel launched its first products, dipstick-based pregnancy tests, in 1983. Since such time, Quidel’s product base and technology platforms have expanded through internal development and acquisitions of other products, technologies and companies. Quidel’s diagnostic solutions aid in the detection and diagnosis of many critical diseases and other medical conditions, including infectious diseases, cardiovascular diseases and conditions, women’s health, gastrointestinal diseases, autoimmune diseases, bone health and thyroid diseases.

In 2017, Quidel acquired the Triage® MeterPro® cardiovascular and toxicology business, and B-type Natriuretic Peptide (“BNP”) assay business run on Beckman Coulter analyzers from Alere Inc., which added an extensive cardiovascular and toxicology menu to its innovative medical diagnostics portfolio.

Products

Quidel provides diagnostic testing solutions under various brand names, including, among others, the following: Quidel®, QuickVue, QuickVue+®, QVue™, Sofia®, Triage, Solana®, Virena®, MicroVue™, Lyra®, FreshCells™, D3®, FastPoint®, ReadyCells®, Super E-Mix™, InflammaDry®, AdenoPlus®, ELVIRA®, ELVIS®, Thyretain® and Savanna®.

The products and platforms under each product category are described below.

Rapid Immunoassay. The rapid immunoassay product category includes the Sofia and Sofia 2 analyzers and the QuickVue, InflammaDry and AdenoPlus products. Sofia is the brand name for Quidel’s fluorescent immunoassay systems. The easy-to-use Sofia and Sofia 2 analyzers combine unique software and Sofia fluorescent immunoassay tests to yield an automatic, objective result that is readily available on the instrument’s screen, in a hard-copy printout, and in a transmissible electronic form that can network via a lab information system to hospital and medical center databases. Quidel launched the Sofia analyzer in 2011 and Sofia 2 in 2017. These systems provide for different operational modes to accommodate both small and large laboratories, as well as other features designed to facilitate use in a variety of healthcare settings, including hospitals, medical centers, and small clinics. Sofia 2 systems include additional benefits and features at a cost point that allows us to better address the lower-volume segment of the diagnostic testing market. Sofia 2 analyzers also incorporate enhanced optics, which provide added performance benefits and enable positive test results to be read in as few as three minutes. In 2021, Quidel also received an emergency use authorization to market its Sofia Q platform that offers similar features and benefits to the Sofia analyzers in a smaller and less expensive format.

QuickVue is the brand name for Quidel’s rapid, visually-read, lateral flow immunoassay products. Quidel has been a leader in the development and production of high-quality lateral flow diagnostics since the early 1990s and offers a broad portfolio of products to diagnose a wide variety of infectious diseases and medical conditions. The QuickVue At-Home OTC COVID-19 test has also recently become a leading at-home COVID-19 product for home use and is available through many retail and online outlets.

170

The InflammaDry and AdenoPlus products are rapid, lateral-flow based, point-of-care (“POC”) products for the detection of infectious and inflammatory diseases and conditions of the eye. InflammaDry is a test that detects elevated levels of MMP-9, a key inflammatory marker for dry eye. AdenoPlus is a test that differentiates between a viral and bacterial infection of acute conjunctivitis (pink eye).

Cardiometabolic Immunoassay. The cardiometabolic immunoassay product category includes the Triage MeterPro, Quidel’s portable testing platform that runs a comprehensive menu of tests that enable physicians to promote improved health outcomes through the rapid diagnosis of critical diseases and health conditions, as well as the detection of certain drugs of abuse. This system aids in the diagnosis, assessment and risk stratification of patients having critical care issues, including congestive heart failure, acute coronary syndromes, and acute myocardial infarction, and can reduce hospital admissions and improve clinical and economic outcomes. Triage cardiovascular rapid tests include immunoassays for BNP, creatine kinase-MB, d-dimer, myoglobin, troponin I and N-terminal pro-Brain Natriuretic Peptide (“NT-proBNP”). Triage tests for Troponin I, high sensitivity Troponin I, PlGF and NT-proBNP, as well as certain test panels which include a combination of immunoassays, are not available for sale in the United States. Quidel has also offered a version of the Triage BNP Test for use on Beckman Coulter Inc. lab analyzers historically but has nearly completed the transition of this business to Beckman Coulter following entry into agreements with Beckman Coulter to resolve litigation between Quidel and Beckman Coulter and provide for the transition of the BNP business to Beckman Coulter.

Additional information about Ortho and its subsidiaries is included in documents incorporated by reference into this joint proxy statement/prospectus. See the section entitled “Where You Can Find More Information” of this joint proxy statement/prospectus.

Overview of Business

Ortho is a pure-play IVD business, pioneering life-impacting advances in diagnostics for over 80 years, from our earliest work in blood typing to our innovation in infectious diseases and our latest developments in laboratory solutions. Ortho is driven by its credo, “Because Every Test is A Life.” This guiding principle reflects the crucial role diagnostics play in global health and guides its priorities as an organization. As a leader in IVD, Ortho impacts approximately 800,000 patients every day. Ortho is dedicated to improving outcomes for these patients and saving lives through providing innovative and reliable diagnostic testing solutions to the clinical laboratory and transfusion medicine communities. Ortho’s global infrastructure and commercial reach allow Ortho to serve these markets with significant scale. Ortho has an intense focus on the customer. Ortho supports its customers with high quality diagnostic instrumentation, a broad test portfolio and market leading service. Ortho’s products deliver consistently fast, accurate and reliable results that allow clinicians to make better-informed treatment decisions. Ortho’s business model generates significant recurring revenues and strong cash flow streams, primarily from the ongoing sales of high margin consumables. In fiscal 2021, these recurring revenues contributed approximately 93% of Ortho’s total and core revenue. Ortho maintains close connectivity with its customers through its global presence, with more than 4,800 employees, including approximately 2,300 commercial sales, service and marketing teammates. This global organization allows it to support its customers across more than 130 countries and territories.

In 2014, Ortho was acquired by The Carlyle Group (“Carlyle”) from Johnson & Johnson and became an independent organization, solely focused on delivering high quality IVD products and service to its diagnostic customer base. At the time of the separation, its business had global scale, a reputation for high quality products, a strong quality management system and a research and development team with extensive scientific expertise. IVD testing is a critical tool in evaluating health in many different settings around the world. IVD is a core component of routine healthcare check-ups for those who are presenting with symptoms or require procedures, and it influences up to 70% of critical healthcare clinical decision-making. Consequently, its IVD solutions have a profound impact on the assessment of health and the delivery of care. IVD is also critical in monitoring the transmission and spread of infectious disease outbreaks, where Ortho’s longstanding excellence in infectious disease testing is particularly relevant. Ortho’s solutions are central to the operations of hospitals, clinics, blood banks and donor centers around the world, where they are used to help diagnose certain conditions, such as cancer or heart attacks, and infectious diseases, such as hepatitis, HIV, and most recently, COVID-19, where Ortho has launched four antibody tests and an antigen test, and Ortho is actively expanding its menu of tests to address the global pandemic.

Ortho operates two lines of business, Clinical Laboratories and Transfusion Medicine, which together generate its core revenue:

| • |  | Clinical Laboratories: Focused on (i) clinical chemistry, which is the measurement of target chemicals in bodily fluids for the evaluation of health and the clinical management of patients, (ii) immunoassay instruments, which test the measurement of proteins as they act as antigens in the spread of disease, antibodies in the immune response spurred by disease, or markers of proper organ function and health, and (iii) testing to detect and monitor disease progression across a broad spectrum of therapeutic areas, and includes grant revenue related to development of Ortho’s COVID-19 antibody and antigen tests.

174

| • |  | Transfusion Medicine: Focused on (i) immunohematology instruments and tests used for blood typing to ensure patient-donor compatibility in blood transfusions; and (ii) donor screening instruments and tests used for blood and plasma screening for infectious diseases for customers primarily in the United States.

Ortho’s broad offerings allow it to support its customer base and maximize the opportunity to provide each of its customers with a comprehensive array of products and services over time. Ortho refers to this mutually beneficial approach as focusing on LCV. Ortho’s focus on LCV underpins everything it does, from the design and execution of its commercial and service model, to its instrument and assay innovation, to the composition of its global footprint. Ortho’s approach has informed its choice to focus on medium- to high-volume laboratories (Ortho’s “Focus Markets”), which in turn has helped it become a leader in its Focus Markets and transformed its financial profile. Ortho intends to continue to invest in and evolve its LCV framework to best support its customers and maximize its financial results.

As an example, Ortho may begin a Clinical Laboratories customer relationship by providing a standalone instrument (often a clinical chemistry analyzer) and a set of assays that are relevant to that customer’s specific testing needs. In 2021, approximately 73% of its Clinical Laboratories installed base was comprised of standalone instruments. As the customer and its testing needs grow, Ortho looks to migrate the customer, where appropriate, to an integrated analyzer that performs both clinical chemistry and immunoassay testing. This migration helps Ortho increase its customers’ testing capabilities as well as the revenue it generates from customers. Building on its differentiation in dry chemistry, Ortho grew its integrated instrument installed base at a compound annual growth rate (“CAGR”) of approximately 13% from 2015 to 2021, and in 2021, approximately 27% of its Clinical Laboratories installed base was comprised of integrated instruments. For its larger customers, Ortho ultimately may expand its testing throughput by installing automation tracks that connect multiple analyzers along the automation track, while providing the full suite of its ever-expanding assay menu. In 2021, approximately 2% of its Clinical Laboratories installed base was comprised of automated systems. As Ortho has significantly expanded its test menu offering, its integrated analyzers are now more often where its Clinical Laboratories relationship starts. In Transfusion Medicine, the life cycle is similar, as customers graduate from manual testing processes to semi-automated capabilities to fully-automated blood and plasma screening instrumentation as their testing volumes and technical competencies grow over time. In 2021, its installed base of Immunohematology instruments grew approximately 3%. Ortho focuses on building long-term customer relationships and continuing to enhance both its offering and the customer’s ability to care for their patients, ultimately deepening its commercial relationship and driving its financial model.

Ortho’s Competitive Strengths

Ortho believes it is well positioned to drive sustained and profitable growth through its relentless focus on LCV. This customer-centric approach informs the execution of its commercial and service model and underpins its go-to-market strategy. Ortho’s customer focus allows it to retain and grow its customers by providing a superior customer experience driven by unparalleled quality of service, continuous innovation and access to a diverse product portfolio. Ortho is able to leverage its global footprint to gain differentiated and leading positions across its Focus Markets. This intense focus on its customers has resulted in an attractive business model with high recurring revenues that allows it to continue to invest to reinforce its competitive strengths, which include:

Ortho’s ability to respond to the full spectrum of its customers’ needs allows it to focus on and enhance LCV. Ortho supplements its instrument and assay offerings with its leading service, commercial, and operational excellence, which Ortho believes improves its customer retention, sales growth and profitability.

Ortho is a leader in its Focus Markets with leading positions in Clinical Laboratories and Transfusion Medicine. The market opportunities for its Clinical Laboratories and Transfusion Medicine businesses are largely connected and, in both Clinical Laboratories and Transfusion Medicine, Ortho can adapt and grow with its customers as they move from lower throughput to more automated solutions. In addition, Ortho has developed a strategy for new product introductions in order to enhance LCV. For example, in its Transfusion Medicine business, Ortho introduced semi-automated capabilities to increase its participation in certain emerging markets, such as China, Asia Pacific and Latin America, and continue the shift of certain customers from manual to semi-automated testing.

175

In Donor Screening, Ortho is a leading player and in late 2020, it won a five-year contract with a five-year extension option with Creative Testing Solutions, the largest U.S. blood donation testing organization, which provides testing for a majority of the U.S. blood supply and is jointly owned by three of the leading U.S. blood service providers: the American Red Cross, OneBlood and Vitalant. Pursuant to this contract, Ortho is Creative Testing Solutions’ primary supplier of serology Donor Screening testing in the United States. This contract provides for collaborative research and development on Ortho’s next generation Donor Screening instrument. With renewed commitment to the Donor Screening market and joint innovation with this customer, Ortho believes this relationship has the potential to support further growth in other international Donor Screening markets over time.

Ortho’s business model and customer-centric approach results in strong customer loyalty and a compelling financial profile with greater than 90% recurring revenue during fiscal 2021. The combination of its revenue growth and leading margin profile allows it to reinvest in innovation and commercial opportunities. In addition, Ortho believes its broad portfolio and diversified end markets provide a resilient growth profile. For instance, its strength in acute care and infectious disease testing is durable as it requires on-demand testing. Most of these tests are conducted in in-patient laboratories and demand tends to be insulated from economic downturns. In addition, Ortho believes the on-site laboratory contributes meaningfully to many of its hospital customers’ earnings and that its core market is relatively insulated from outsourcing to reference laboratories. Ortho believes this combination of product and end market diversification allowed it to generally outperform the market on a core revenue growth basis during the COVID-19 pandemic and Ortho believes this resiliency will continue into the future.

Superior customer experience and brand loyalty resulting in high customer retention and win rates

Ortho delivers industry-leading test performance in a way that is easy for laboratory directors and technical staff to manage their operations on a daily basis, which leads to excellent customer appeal and loyalty. In 2015, Ortho launched ORTHOCARE with the goal of providing best-in-class service and support program for hospitals, hospital networks, blood banks and laboratories. Ortho’s ORTHOCARE service program is a critical element of the superior customer experience that Ortho delivers to its customers. Since forming ORTHOCARE, Ortho was the highest recommended manufacturer for the last six consecutive years (2016 through 2021) in a survey of clinical laboratory professionals in U.S. hospitals conducted by ServiceTrak. In the same survey in 2021, Ortho was ranked #1 in seven out of eight categories relating to its manufacturing, system and service performance.

In Ortho’s Focus Markets, the simplicity and reliability of its instruments and tests often reduces the need for staff hands-on time, producing a lower total cost of ownership for its customers. Ortho believes that after instrument cost, the quality of service is the largest driver of customer choice when selecting a Clinical Laboratories vendor. Ortho’s superior service and customer performance contribute to its revenue retention rate of approximately 98% in 2021 and its average Clinical Laboratories and Transfusion Medicine customer relationships of almost 13 years and 15 years, respectively.

In Clinical Laboratories, beyond the simplicity of dry chemistry slides, Ortho offers instrument e-connectivity, customizable automation tracks, a suite of upgraded quality control reagents and market-leading calibration stability, producing higher efficiency and lower total cost of ownership. In Transfusion Medicine, its ORTHO VISION platform has expanded its leadership position because it automated and simplified the test workflow for time-strained blood bank staff, increasing throughput and efficiency.

Ortho’s dedicated and highly respected Global Leadership Team (“GLT”) is comprised of 16 members with significant experience in the IVD and healthcare industries. For instance, Ortho’s Chair and Chief Executive Officer, Chief Financial Officer, Chief Innovation Officer, General Counsel, and Executive Vice President of Commercial Excellence and Strategy each have more than 25 years of experience in their respective fields of expertise and together have more than 125 years of experience with IVD or commercial healthcare companies. These individuals are supported by their GLT colleagues with extensive industry knowledge and long-term experience leading at Ortho or other multinational companies in the IVD industry. Under their leadership Ortho has transformed its mindset from standing up the business to executing on its growth strategies by increasing its customer focus and its emphasis on innovation and operational efficiency. Ortho believes that the industry knowledge and dedication of its GLT members, combined with their long-term experience profitably growing multinational companies, are instrumental for the successful execution of its growth strategy going forward.

Ortho’s Growth Strategy

Ortho’s heritage and strength lie in its long-term customer relationships and trusted brand, which create a steady base of recurring revenue and a foundation for future growth. By focusing on LCV, Ortho identifies ways in which it can utilize product innovation and impactful customer service and solutions to deepen these partnerships and add value over time. Ortho plans to grow its business by broadening its existing relationships, winning new customers and targeting high-growth end markets and adjacencies. Ortho is focused on sustainable long-term growth through commercial excellence that maximizes LCV, strengthens existing relationships through superior service and delivers innovative products for its customers and their patients. The key elements of its strategy to accelerate and sustain revenue growth and operating leverage include:

Focusing relentlessly on maximizing LCV, which is designed to produce and maintain a growing and recurring, high margin, durable financial profile and contributes to growth

Over its more than 80 years supporting the IVD testing needs of its customers, Ortho has developed deep and enduring relationships with its customers. Ortho seeks to expand its relationship with both new and existing customers by offering them higher throughput integrated instrumentation, automation, and an expanding assay menu that grows with them as their needs evolve. On average globally, when one of its Clinical Laboratories customers upgrades from a standalone instrument to an integrated instrument, Ortho typically sees an increase in annual consumable revenues of approximately 65%. After this initial increase in utilization, Ortho typically sees that customer’s recurring revenues increase by approximately 3% to 7% on

177

an annual basis. In Ortho’s experience, by the time a customer is running sufficient volumes of tests to consider automation, annual reagent purchases have roughly doubled, and upgrading to an automated instrument increases this average by an additional 27%. This combined effect leads to an average increase of approximately 300% in annual revenues as a customer upgrades from an initial integrated placement to automation installation. In Transfusion Medicine, the pattern is even more striking. When customers move from manual testing to a semi-automated solution, the customers typically experience an approximately 70% increase in workflow efficiency, and Ortho sees an average 600% increase in revenues. When they graduate to Ortho’s fully automated ORTHO VISION instruments, these customers typically experience a 90% improvement in workflow efficiency and Ortho sees an additional increase of approximately 90% on average in recurring revenue.

Embedded in Ortho’s strategy of developing new integrated analyzers and bringing them to market is the parallel refurbishment of used analyzers and resale of these systems, primarily in emerging markets. Ortho is focusing increased investment in market-appropriate products and local capabilities in order to gain market share in emerging markets and enhance its overall growth.

Ortho believes there are six key trends affecting its end markets that will drive increasing demand for its products and solutions and offer new opportunities for business expansion:

| • |  | Aging population and increased need for testing of chronic conditions. Populations continue to age, particularly in the developed economies, which is driving increased prevalence of both chronic conditions and the acute diseases of later life, such as cancer, cardiac disease, and neurodegenerative disorders. This demographic trend is leading to an increase in surgical volumes and supports growing demand for diagnostic testing and pre-surgical screening on both an acute and routine health screening basis, and accounts for a significant portion of ongoing test menu expansion.

| • |  | Expansion of healthcare, particularly in emerging markets. Continuing economic growth in emerging markets is increasing the size of the middle class and available disposable income, expanding resources available for healthcare. With most health decisions informed by diagnostic testing, economic development is driving instrument purchases and higher test volumes.

| • |  | Consolidation and automation. Hospitals and laboratories continue to merge into larger healthcare systems. This trend, combined with a shortage of skilled laboratory technicians, has driven consolidation of testing volumes into medium- to high-volume centralized laboratories with fully automated instruments. These automated instruments offer higher test throughput versus standalone specialty instruments. To enhance productivity, these platforms are also often connected by software and automation tracks to enable more seamless routing and testing of patient samples.

| • |  | Digital solutions and informatics. Diagnostic tests generate information that aids in clinical practice or the study of health and disease. This data, combined with the advancement of internet applications and software, offer new ways to create value for hospital and laboratory customers. Tying test data into laboratory information and electronic medical record systems is only the starting point. Digital solutions can also help laboratories manage test utilization, efficiency and inventory, aid in clinical decision support and pool test data for research purposes.

| • |  | New diagnostic technologies and continued decentralization. Diagnostics continue to advance with new technologies changing and improving test accuracy and operational performance. New modalities have emerged with the advent of molecular and genetic diagnostics, the expansion of proteomics supporting improved and broader immunoassay testing, and technologies like miniaturization, sensors, and microfluidics enabling point-of-care testing. Diagnostic testing at emergency room and intensive care unit bedsides in the hospital, physician offices, urgent care centers, pharmacy minute clinics and at the patient’s home is increasing. These technologies are creating new opportunities within IVD and growth for the broader IVD market overall. As the COVID-19 pandemic has underscored, point-of-care tests typically have lower test accuracy than those performed on central lab instruments, are often more expensive on a per test basis and can struggle with throughput for mass screening.

| • |  | Emergence and identification of new diseases and treatments to include plasma based therapies. The COVID-19 pandemic is the most salient example of the continuing emergence of new infectious diseases on a global scale which highlights the importance of accurate and efficient diagnostic testing. Ortho has witnessed the emergence of HIV, Ebola, Zika, SARS and MERS, and it is estimated that one new infectious disease is emerging every year. New diagnostic tests and test volumes are driven both by the emergence of new diseases and by the discovery of new or improved markers for disease. Beyond infectious diseases, significant assay innovation is occurring in a range of therapy areas, including oncology, neurology and cardiovascular disease.

Ortho’s Products, Pipeline and Services

Throughout eight decades of innovation, Ortho has been a leader in the diagnostics field and brought multiple innovations to market such as testing for RH phenotyping, HCV, Chagas’ Disease, and most recently COVID-19. Since its separation from Johnson & Johnson, Ortho has engineered and delivered six new instrument platforms to market and expanded its assay offering with over 120 new or improved assays, which has increased its product vitality and revenue growth.

Our revenue is driven by a “razor-razor blade” business model. Through this model, we generally sell or place instruments under long-term contracts, which support the ongoing sale of our assays, reagents and consumables. Our instruments are closed systems, requiring customers to purchase the assays, reagents and consumables from us. These sales generate a high proportion of recurring revenues. As of January 2, 2022, we had an installed base of approximately 21,000 instruments, which increased approximately 3% since January 3, 2021.

Clinical Laboratories

Ortho has been a pioneer of important technological advances in clinical diagnostics, including its unique dry slide technology which offers customers superior test performance with clear ease-of-use advantages and lower total cost of ownership. Dry slide technology combines the spreading, masking, scavenger and reagent layers into one postage-stamp-sized slide that provides clinicians with high-quality results quickly, efficiently and economically. Ortho’s slides are very stable. The current approximate six-month span between calibrations for slides is industry-leading and Ortho expects this to be significantly improved through ongoing research and development. Ortho carries a comprehensive clinical chemistry test menu, and dry slides have long shelf life with lower laboratory shelf space required. Ortho’s new XT7600 and XT3400 instruments extend these advantages with digital accuracy and XT multi-test slides, and Ortho has a pipeline opportunity to increase multi-test capacity further over time. Ortho’s dry slide chemistry is well positioned for rising environmental concerns given its eco-friendly profile with no water usage and significantly reduced clinical waste and biohazard.

Ortho’s flagship Clinical Laboratories platform is the VITROS family of instruments, which includes a series of clinical chemistry, immunoassay and integrated (combined chemistry and immunoassay) systems and automation and middleware solutions. The VITROS instruments run a wide range of assays, from infectious diseases, sepsis, cardiovascular conditions and anemia, to bone disease, diabetes, drugs of abuse / toxicology, oncology and renal disease. Ortho has six VITROS instrument analyzers that provide standardized performance, and are still sufficiently flexible to meet the needs of its customers across the spectrum of laboratory sizes and volumes. Ortho’s VITROS instruments are placed in centralized, higher-throughput testing sites (hospitals and laboratories) and decentralized, lower-throughput sites (physician offices, clinics and specialty settings).

181

Ortho launched the next generation of VITROS instruments—the XT 7600 integrated system and XT 3400 clinical chemistry analyzer – in 2018 and 2019, respectively. Both instruments deploy a highly accurate, digital reflectometer that measures test results and takes advantage of new XT chemistry slides, combining two tests that are frequently used together, and improving the economics for it and its customers. Additionally, Ortho believes that digital sensing will enable improved test accuracy through better image processing over time. Ortho believes the XT instruments offer several important advancements over prior generations:

| • |  | 40% greater test throughput when using its XT-slides

| • |  | 96% first-pass yield on test results

| • |  | Designed to offer high reliability with a 98% up-time guarantee for U.S. customers

Ortho’s Clinical Laboratories assay menu is quite broad, covering 24 different therapeutic areas and approximately 90% of a typical laboratory’s testing needs. Ortho is particularly known for the strength of its dry clinical chemistry tests, as well as infectious disease and acute care immunoassays, including its high-performing cardiac markers for heart attack and congestive heart failure. In Greater China, for example, Ortho believes it is the clinical chemistry market leader in separate “STAT” testing laboratories that seek rapid, high-performing assays to drive rapid clinical decisions.

Suppliers and Raw Materials

Ortho obtains raw materials from reputable outside suppliers and believes its business relationships with them are good. Some of its products are derived from source biologic materials, which are available from a limited number of sources. To date, Ortho has been able to obtain sufficient quantities of required materials for use in manufacturing its products, but there can be no assurance that a sufficient supply of required materials will always be available to it. Ortho employs a number of strategies to mitigate raw material supply risk, including managing safety stock inventories as well as developing second sources for key raw materials.

In addition, Ortho has recently encountered some increasing pressures on raw material pricing. Ortho employs a number of strategies to mitigate raw material price increases, including identifying alternative sources for raw materials and implementing operational efficiencies.

Ortho sources certain instruments from industry specific suppliers. Ortho believes that its business relationships with its instrument suppliers are good. Each instrument supplier is placed under a contract that provides terms and conditions designed to preserve business continuity. In the event either party terminates the agreement, the “out clauses” provide sufficient time to effect a transition to a new supplier and maintain supply continuity. This transition would also be characterized by the build of a strategic inventory to bridge any time period required to initiate supply from an alternate provider.

Ortho has experienced and continues to manage through supply chain challenges relating to key components of its instruments. For instance, Ortho has experienced supply chain shortages of certain key components of its instruments and assays, which are impacting Ortho’s ability to fulfill customer orders on a timely basis and have had, and are expected to

186

continue to have, a negative impact on Ortho’s business and results of operations, which could be material. Ortho is continuing to work closely with its primary suppliers of these components, alongside their downstream supply chain, in order to maintain supply to its customers. In addition, Ortho is employing a number of strategies to mitigate supply chain shortages, including pursuing additional suppliers for certain of these key components. See “Risk Factors—Risks Relating to Ortho’s Business—Ortho has significant international sales and operations and faces risks related to health epidemics, including the ongoing global pandemic related to COVID-19. Ortho’s business, consolidated results of operations, financial position and cash flows have been and may continue to be negatively affected by the COVID-19 pandemic” and “Risk Factors—Risks Relating to Ortho’s Business—Ortho relies on certain suppliers and manufacturers for raw materials, components for Ortho’s products and services, and fluctuations in the availability and price of such materials, products and services may interfere with Ortho’s ability to meet Ortho’s customers’ needs.”

Ortho believes that all of its manufacturing and distribution facilities are operated in compliance with existing environmental requirements in all material respects, including the operating permits required thereunder. Although Ortho does not currently expect the costs of compliance with existing environmental requirements to have a material impact on its financial position, Ortho may incur additional costs or obligations to comply with environmental and health and safety requirements as a result of changes in law or customer demands, including those relating to its products. In addition, many of its manufacturing sites have a long history of industrial operations, and remediation is or may be required at a number of these locations. Although Ortho does not currently expect outstanding remediation obligations to have a material impact on its financial position, the ultimate cost of remediation is subject to a number of variables and is difficult to accurately predict. See “Risk Factors—Risks Relating to Ortho’s Business—Ortho could incur costs complying with environmental and health and safety requirements, or as a result of liability for contamination or other potential environmental harm or liability caused by its operations.”

Government Regulation

Ortho’s products and operations are subject to extensive regulation by the FDA and other federal and state authorities in the United States, as well as comparable authorities in foreign jurisdictions. In the United States, its products are regulated as either medical devices under the Federal Food, Drug, and Cosmetic Act (“FDCA”) and its implementing regulations, or as biological products under the FDCA and the Public Health Service Act (“PHSA”) and their implementing regulations, each as amended and enforced by the FDA. The FDA regulates the development, design, non-clinical and clinical research, manufacturing, safety, efficacy, labeling, packaging, storage, installation, servicing, recordkeeping, premarket clearance or approval, adverse event reporting, advertising, promotion, marketing and distribution, and import and export of medical devices and biological products to ensure that such products distributed domestically are safe and effective for their intended uses and otherwise meet the applicable requirements of the FDCA and PHSA.

U.S. Regulation of Medical Devices

The majority of Ortho’s diagnostic products and analyzers are regulated by the FDA as medical devices in the United States. Unless an exemption applies, each medical device commercially distributed in the United States requires either FDA clearance of a 510(k) premarket notification, or approval of a PMA application. Under the FDCA, medical devices are classified into one of three classes-Class I, Class II or Class III-depending on the degree of risk associated with each medical device and the extent of manufacturer and regulatory control needed to ensure its safety and effectiveness. Class I devices are those with the lowest risk to the patient and are those for which safety and effectiveness can be assured by adherence to the FDA’s General Controls for medical devices, which include compliance with the applicable portions of current good manufacturing practices (“cGMPs”) for medical devices known as the Quality System Regulation (“QSR”) facility registration and product listing, reporting of adverse medical events, and truthful and non-misleading labeling, advertising, and promotional materials. Class II devices are subject to the FDA’s General Controls, and special controls as deemed necessary by the FDA to ensure the safety and effectiveness of the device. These special controls can include performance standards, post-market surveillance, patient registries and FDA guidance documents. Devices deemed by the FDA to pose the greatest risks, such as life sustaining, life supporting or some implantable devices, or devices that have a new intended use, or use advanced technology that is not substantially equivalent to that of a legally marketed device, are placed in Class III.

While most Class I devices are exempt from the 510(k) premarket notification requirement, manufacturers of most Class II devices are required to submit to the FDA a premarket notification under Section 510(k) of the FDCA requesting permission to commercially distribute the device. The FDA’s permission to commercially distribute a device subject to a 510(k)

189

premarket notification is generally known as 510(k) clearance. Class III devices require approval of a PMA application evidencing safety and effectiveness of the device. Ortho currently markets the majority of its diagnostic products in the United States pursuant to 510(k) clearances and PMA approvals.

To obtain 510(k) clearance, a manufacturer must submit a premarket notification demonstrating to the FDA’s satisfaction that the proposed device is “substantially equivalent” to another legally marketed device that itself does not require PMA approval (a predicate device). A predicate device is a legally marketed device that is not subject to premarket approval, i.e., a device that was legally marketed prior to May 28, 1976 (pre-amendments device) and for which a PMA is not required, a device that has been reclassified from Class III to Class II or I, or a device that was found substantially equivalent through the 510(k) process. The FDA’s 510(k) clearance process usually takes from three to twelve months, but often takes longer. FDA may require additional information, including clinical data, to make a determination regarding substantial equivalence. In addition, the FDA collects user fees for certain medical device submissions and annual fees for medical device establishments.

If the FDA agrees that the device is substantially equivalent to a lawfully marketed predicate device, it will grant 510(k) clearance to authorize the device for commercialization. If the FDA determines that the device is “not substantially equivalent,” the device is automatically designated as a Class III device. The device sponsor must then fulfill more rigorous PMA requirements, or can request a risk-based classification determination for the device in accordance with the de novo classification process, which is a route to market for novel medical devices that are low to moderate risk and are not substantially equivalent to a predicate device.

After a device receives 510(k) clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a major change or modification in its intended use, will require a new 510(k) clearance or, depending on the modification, PMA approval or de novo classification. The FDA requires each manufacturer to determine whether the proposed change requires submission of a 510(k), de novo classification request or a PMA in the first instance, but the FDA can review any such decision and disagree with a manufacturer’s determination. If the FDA disagrees with a manufacturer’s determination not to seek a new 510(k) or other form of marketing authorization for the modification to the 510(k)-cleared product, the FDA can require the manufacturer to cease marketing and/or request the recall of the modified device until 510(k) clearance or PMA approval is obtained or a de novo classification is granted.

The PMA process is more demanding than the 510(k) premarket notification process. In a PMA, the manufacturer must demonstrate that the device is safe and effective, and the PMA must be supported by extensive data, including data from preclinical studies and human clinical trials. All clinical investigations of devices to determine safety and effectiveness must be conducted in accordance with the FDA’s investigational device exemption (“IDE”) regulations which govern investigational device labeling, prohibit promotion of the investigational device, and specify an array of recordkeeping, reporting and monitoring responsibilities of study sponsors and study investigators. If the device presents a “significant risk,” to human health, as defined by the FDA, the FDA requires the device sponsor to submit an IDE application to the FDA, which must become effective prior to commencing human clinical trials. A significant risk device is one that presents a potential for serious risk to the health, safety or welfare of a patient and either is implanted, used in supporting or sustaining human life, substantially important in diagnosing, curing, mitigating or treating disease or otherwise preventing impairment of human health, or otherwise presents a potential for serious risk to a subject. In addition, the study must be approved by, and conducted under the oversight of, an Institutional Review Board (“IRB”) for each clinical site. The IRB is responsible for the initial and continuing review of the IDE, and may pose additional requirements for the conduct of the study. If the device presents a non-significant risk to the patient, a sponsor may begin the clinical trial after obtaining approval for the trial by one or more IRBs without separate approval from the FDA, but must still follow abbreviated IDE requirements, such as monitoring the investigation, ensuring that the investigators obtain informed consent, and labeling and record-keeping requirements.

In addition to clinical and preclinical data, the PMA must contain a full description of the device and its components, a full description of the methods, facilities, and controls used for manufacturing, and proposed labeling. Following receipt of a PMA, the FDA determines whether the application is sufficiently complete to permit a substantive review. If FDA accepts the application for review, it has 180 days under the FDCA to complete its review of a PMA, although in practice, the FDA’s review often takes significantly longer, and can take up to several years. An advisory panel of experts from outside the FDA may be convened to review and evaluate the application and provide recommendations to the FDA as to the approvability of the device. The FDA may or may not accept the panel’s recommendation. In addition, the FDA will generally conduct a pre-approval inspection of the applicant or its third-party manufacturers’ or suppliers’ facilities to ensure compliance with the QSR.

190

The FDA will approve the new device for commercial distribution if it determines that the data and information in the PMA constitute valid scientific evidence and that there is reasonable assurance that the device is safe and effective for its intended use(s). The FDA may approve a PMA with post-approval conditions intended to ensure the safety and effectiveness of the device, including, among other things, restrictions on labeling, promotion, sale and distribution, and collection of long-term follow-up data from patients in the clinical study that supported PMA approval or requirements to conduct additional clinical studies post-approval. The FDA may condition PMA approval on some form of post-market surveillance when deemed necessary to protect the public health or to provide additional safety and efficacy data for the device in a larger population or for a longer period of use. In such cases, the manufacturer might be required to follow certain patient groups for a number of years and to make periodic reports to the FDA on the clinical status of those patients. Failure to comply with the conditions of approval can result in material adverse enforcement action, including withdrawal of the approval. Certain changes to an approved device, such as changes in manufacturing facilities, methods, or quality control procedures, or changes in the design performance specifications, which affect the safety or effectiveness of the device, require submission of a PMA supplement, or in some cases a new PMA.

In addition to the 510(k) clearance, PMA, and de novo classification pathways to market, the Commissioner of the FDA, under delegated authority from the Secretary of HHS may, under certain circumstances in connection with a declared public health emergency, allow for the marketing of a product that does not otherwise comply with FDA regulations by issuing an EUA for such product. Before an EUA may be issued by HHS, the Secretary must declare an emergency based on a determination that a public health emergency exists that effects or has the significant potential to affect, national security, and that involves a specified biological, chemical, radiological, or nuclear agent or agents, or a specified disease or condition that may be attributable to such agent or agents. On February 4, 2020, the HHS Secretary determined that the novel coronavirus presented a public health emergency that has a significant potential to affect national security or the health and security of U.S. citizens living abroad and declared that circumstances existed justifying the authorization of emergency use of in vitro diagnostics for detection and/or diagnosis of the novel coronavirus that causes COVID-19.

In order to be the subject of an EUA, the FDA Commissioner must conclude that, based on the totality of scientific evidence available, it is reasonable to believe that the product may be effective in diagnosing, treating, or preventing a disease attributable to the agents described above, that the product’s potential benefits outweigh its potential risks and that there is no adequate, approved alternative to the product. Products subject to an EUA must still comply with the conditions of the EUA, including labeling and marketing requirements. Moreover, the authorization to market products under an EUA is limited to the period of time the public health emergency declaration is in effect. In the U.S., Ortho markets its VITROS Anti-SARS-CoV-2 IgG Antibody test and calibrators and controls and VITROS Anti-SARS-CoV-2 Total Antibody test and calibrators and controls pursuant to EUAs originally granted by the FDA in April 2020, and Ortho markets its VITROS Anti-SARS-CoV-2 Antigen Test pursuant to an EUA originally granted by the FDA on January 11, 2021.

After a device is cleared or approved or otherwise authorized for marketing, numerous pervasive regulatory requirements continue to apply unless explicitly exempt. These include:

| • |  | establishment registration and device listing with the FDA;

| • |  | QSR requirements, which require manufacturers, including third-party manufacturers, to follow stringent design, testing, control, documentation and other quality assurance procedures during all aspects of the design and manufacturing process;

| • |  | labeling and marketing regulations, which require that promotion is truthful, not misleading, fairly balanced and provide adequate directions for use and that all claims are substantiated, and also prohibit the promotion of products for unapproved or “off-label” uses and impose other restrictions on labeling; FDA guidance on off-label dissemination of information and responding to unsolicited requests for information;

| • |  | clearance or approval of product modifications to 510(k)-cleared devices that could significantly affect safety or effectiveness or that would constitute a major change in intended use of one of its cleared devices;

| • |  | medical device reporting regulations, which require that a manufacturer report to the FDA if a device it markets may have caused or contributed to a death or serious injury, or has malfunctioned and the device or a similar device that it markets would be likely to cause or contribute to a death or serious injury, if the malfunction were to recur;

| • |  | correction, removal and recall reporting regulations, which require that manufacturers report to the FDA field corrections and product recalls or removals if undertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health;

191

| • |  | complying with requirements governing Unique Device Identifiers on devices and also requiring the submission of certain information about each device to the FDA’s Global Unique Device Identification Database;

| • |  | the FDA’s recall authority, whereby the agency can order device manufacturers to recall from the market a product that is in violation of governing laws and regulations; and

| • |  | post-market surveillance activities and regulations, which apply when deemed by the FDA to be necessary to protect the public health or to provide additional safety and effectiveness data for the device.

U.S. Regulation of Biological Products

Certain of Ortho’s blood screening products are regulated by the FDA as biological products, also called biologics. In the United States, biologics are subject to regulation under the FDCA, PHSA, and other federal, state, local and foreign statutes and regulations. The process required by the FDA before biologics may be marketed in the United States generally involves the following:

| • |  | completion of preclinical laboratory tests and animal studies performed in accordance with the FDA’s Good Laboratory Practice requirements;

| • |  | submission to the FDA of an Investigational New Drug application (“IND”) which must become effective before clinical trials may begin;

| • |  | approval by an IRB or ethics committee at each clinical site before the trial is commenced;

| • |  | performance of adequate and well-controlled human clinical trials to establish the safety, purity and potency of the proposed biologic product candidate for its intended purpose;

| • |  | preparation of and submission to the FDA of a BLA after completion of all pivotal clinical trials;

| • |  | satisfactory completion of an FDA Advisory Committee review, if applicable;

| • |  | a determination by the FDA within 60 days of its receipt of a BLA to file the application for review;

| • |  | satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities at which the proposed product is produced to assess compliance with cGMPs and to assure that the facilities, methods and controls are adequate to preserve the biological product’s continued safety, purity and potency, and of selected clinical investigation sites to assess compliance with Good Clinical Practices; and

| • |  | FDA review and approval of the BLA to permit commercial marketing of the product for particular indications for use in the United States.

Prior to beginning the first clinical trial of a biologic product candidate in the United States, Ortho must submit an IND to the FDA. An IND is a request for authorization from the FDA to administer an investigational new drug product to humans. An IND must become effective before human clinical trials may begin.

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product development, nonclinical studies and clinical trials are submitted to the FDA as part of a BLA requesting approval to market the product for one or more indications. The BLA must include all relevant data available from preclinical and clinical studies, including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls, and proposed labeling, among other things. Data can come from company-sponsored clinical studies intended to test the safety and effectiveness of a use of the product, or from a number of alternative sources, including studies initiated by independent investigators. The submission of a BLA requires payment of a substantial application user fee to the FDA, unless a waiver or exemption applies.

After the FDA evaluates a BLA and conducts inspections of manufacturing facilities where the investigational product and/or its drug substance will be produced and of select clinical trial sites, the FDA may issue an approval letter or a Complete Response Letter (“CRL”). An approval letter authorizes commercial marketing of the product with specific prescribing information for specific indications. A CRL will describe all of the deficiencies that the FDA has identified in the BLA, except that where the FDA determines that the data supporting the application are inadequate to support approval, the FDA may issue the CRL without first conducting required inspections, testing submitted product lots, and/or reviewing proposed labeling. In issuing the CRL, the FDA may recommend actions that the applicant might take to place the BLA in condition

192

for approval, including requests for additional information or clarification. The FDA may delay or refuse approval of a BLA if applicable regulatory criteria are not satisfied, require additional testing or information and/or require post-marketing testing and surveillance to monitor safety or efficacy of a product.

If regulatory approval of a product is granted, such approval will be granted for particular indications and may entail limitations on the indicated uses for which such product may be marketed. The FDA also may condition approval on, among other things, changes to proposed labeling or the development of adequate controls and specifications. Once approved, the FDA may withdraw the product approval if compliance with pre- and post-marketing requirements is not maintained or if problems occur after the product reaches the marketplace. The FDA may require one or more post-market studies and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization, and may limit further marketing of the product based on the results of these post-marketing studies.

Any biologics manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to record-keeping, reporting of adverse experiences, periodic reporting, product sampling and distribution, and advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are subject to prior FDA review and approval. There also are continuing, annual program fees for any marketed products. Biologic manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP, which impose certain procedural and documentation requirements upon it and its third-party manufacturers. Changes to the manufacturing process are strictly regulated, and, depending on the significance of the change, may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting requirements upon it and any third-party manufacturers that Ortho may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance.

FDA Enforcement

The FDA may withdraw marketing authorization if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information, imposition of post-market studies or clinical studies to assess new safety risks, or imposition of distribution restrictions or other restrictions. Other potential consequences include, among other things: restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market, product recalls, fines, warning letters, untitled letters, clinical holds on clinical studies, refusal of the FDA to approve pending applications or supplements to approved applications, product seizures or detention, refusal to permit the import or export of products, consent decrees, corporate integrity agreements, debarment or exclusion from federal healthcare programs, the issuance of corrective information, injunctions, or the imposition of civil or criminal penalties.

In addition, the FDA closely regulates the marketing, labeling, advertising and promotion of biologics and medical devices. A company can make only those claims relating to safety and efficacy, purity and potency that are cleared or approved by the FDA and in accordance with the provisions of the authorized label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties.

U.S. Healthcare Laws

The costs of healthcare have been and continue to be a subject of study, investigation and regulation by governmental agencies and legislative bodies around the world. In the United States, attention has been focused on programs that encourage doctors to recommend, use or purchase particular medical devices. Payers have become a more potent force in the marketplace and increased attention is being paid to medical device pricing, appropriate medical device utilization and the quality and costs of healthcare generally.

The implementation of the PPACA, in the United States, for example, has changed healthcare financing and delivery by both governmental and private insurers substantially, and affected medical device manufacturers significantly. The PPACA,

193

among other things, provided incentives to programs that increase the federal government’s comparative effectiveness research, and implemented payment system reforms including a national pilot program on payment bundling to encourage hospitals, physicians and other providers to improve the coordination, quality and efficiency of certain healthcare services through bundled payment models. Additionally, the PPACA expanded eligibility criteria for Medicaid programs and created a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research. Since its enactment, there have been judicial, executive and political challenges to certain aspects of the PPACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the PPACA brought by several states without specifically ruling on the constitutionality of the PPACA.

In addition, other legislative changes have been proposed and adopted since the PPACA was enacted. The Budget Control Act of 2011, among other things, reduced Medicare payments to providers by 2% per fiscal year, effective on April 1, 2013 and, due to subsequent legislative amendments to the statute, will remain in effect through 2030, with the exception of a temporary suspension from May 1, 2020, through March 31, 2022, unless additional Congressional action is taken. Additionally, the American Taxpayer Relief Act of 2012, among other things, further reduced Medicare payments to several providers, including hospitals, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. MACRA, enacted on April 16, 2015, repealed the formula by which Medicare made annual payment adjustments to physicians and replaced the former formula with fixed annual updates and a new system of incentive payments that are based on various performance measures and physicians’ participation in alternative payment models such as accountable care organizations. It is unclear what effect new quality and payment programs, such as MACRA, may have on our business, financial condition, results of operations or cash flows.

On January 1, 2018, the Centers for Medicare and Medicaid Services (“CMS”) implemented certain provisions of PAMA, which made substantial changes to the way in which clinical laboratory services are paid under Medicare. Under PAMA, laboratories that receive the majority of their Medicare revenue from payments made under the Clinical Laboratory Fee Schedule or the Physician Fee Schedule are required to report to CMS, beginning in 2017 and every three years thereafter (or annually for “advanced diagnostics laboratory tests”), private payer payment rates and volumes for their tests. Laboratories that fail to report the required payment information may be subject to substantial civil monetary penalties. CMS uses the data to calculate a weighted median payment rate for each test, which is used to establish a revised Medicare reimbursement rate. Under PAMA, the revised Medicare reimbursement rates were scheduled to apply to clinical diagnostic laboratory tests furnished on or after January 1, 2018. The revised reimbursement methodology is expected to generally result in relatively lower reimbursement under Medicare for clinical diagnostic lab tests than has been historically available. Any reduction to payment rates resulting from the new methodology is limited to 10% per test per year in 2018 through 2020, and to 15% per test per year in 2021 through 2023. For clinical diagnostic laboratory tests that are assigned a new or substantially revised Healthcare Common Proceduring Coding System code, initial payment rates for clinical diagnostic laboratory tests that are not advanced diagnostic laboratory tests will be assigned by the cross-walk or gap-fill methodology. Initial payment rates for new advanced diagnostic laboratory tests will be based on the actual list charge for the laboratory test. The CARES Act, which was signed into law on March 27, 2020, amended the timeline for reporting private payer payment rates and delayed by one year the payment reductions scheduled for 2021. On December 10, 2021, Congress passed the PMAFSA, which delays the next data reporting period by an additional year and prevents any reduction in payment amounts from commercial payer rate implementation in 2022.

In addition to the CARES Act, Congress has enacted other laws in response to the COVID-19 pandemic to provide financial relief to healthcare providers and suppliers, including diagnostic laboratories, and encourage implementation of diagnostic testing and treatment for COVID-19. For instance, the FFCRA, enacted on March 18, 2020, requires certain governmental and commercial insurance plans to provide coverage of COVID-19 diagnostic testing services without imposing cost-sharing (e.g., copays, deductibles or coinsurance) or other utilization management requirements. The CARES Act and the PPPHCEA, enacted on April 24, 2020, each appropriated approximately $100 billion to provide financial relief for certain healthcare providers and to expand treatment and diagnostic testing capacity for COVID-19. The CAA, which was enacted on December 27, 2020 and included further pandemic relief measures, temporarily increased payment rates under the Medicare Physician Fee Schedule by 3.75% beginning January 1, 2021 through December 31, 2021. The PMAFSA further established a temporary 3% payment rate increase under the Medicare Physician Fee Schedule that will remain in effect beginning January 1, 2022 through December 31, 2022. The CARES Act, as subsequently amended by the CAA and PMAFSA, also suspended, for the period from May 1, 2020 to March 31, 2022, the 2% payment reduction created under the sequestration required by the Budget Control Act of 2011 (as amended by the American Taxpayer Relief Act of 2012), and extended the sequester by one year, through 2030.

The regulatory agencies under whose purview Ortho operates have administrative powers that may subject it to actions such as product withdrawals, recalls, seizure of products and other civil and criminal sanctions.

194

In addition, business practices in the healthcare industry have come under increased scrutiny, particularly in the United States, by government agencies and state attorneys general, and resulting investigations and prosecutions carry the risk of significant civil and criminal penalties under applicable laws. These laws include anti-kickback, false claims laws, civil monetary penalties laws, data privacy and security laws, and physician payment transparency laws. See “Risk Factors—Risks Relating to Ortho’s Business—Ortho is subject to healthcare regulations that could result in liability, require it to change its business practices and restrict its operations in the future.”

Impact of the Initial Public Offering

Use of proceeds and impact of debt extinguishment

On February 1, 2021, we completed the IPO of our ordinary shares at a price of $17.00 per share. We issued and sold 76,000,000 ordinary shares in the IPO and issued and sold an additional 11,400,000 ordinary shares on February 4, 2021 pursuant to the full exercise of the underwriters’ option to purchase additional shares. The ordinary shares sold in the IPO were registered under the Securities Act pursuant to a Registration Statement on Form S-1, which was declared effective by the SEC on January 29, 2021. Our ordinary shares are listed on Nasdaq under the symbol “OCDX.” The offering, including proceeds from the full exercise of the underwriters’ option to purchase additional shares, generated net proceeds of $1,426.4 million after deducting underwriting discounts and commissions.

We used the net proceeds from the IPO (i) to redeem $160.0 million of our 2025 Notes, plus accrued interest thereon and $11.8 million of redemption premium, (ii) to redeem $270.0 million of our 2028 Notes, plus accrued interest thereon and $19.6 million of redemption premium, (iii) to repay $892.7 million in aggregate principal amount of borrowings under our Dollar Term Loan Facility and (iv) for working capital and general corporate purposes.

Incremental public company expenses

As a recently new public company, we have incurred significant expenses on an ongoing basis that we did not incur as a private company, including increased director and officer liability insurance expense, as well as third-party and internal resources related to accounting, auditing, Sarbanes-Oxley Act compliance, legal and investor and public relations expenses. These costs will generally be included in selling, marketing and administrative expenses in our audited consolidated statement of operations.

Stock-based compensation expense

On May 3, 2021, the Ortho Board of Directors approved the modifications to the vesting of restricted stock and Liquidity Event option awards held by certain current and former members of management in accordance with the 2014 Equity Incentive Plan, which governs these grants. As a result of the modification, we recorded additional stock-based compensation expense of $6.2 million during the fiscal year ended January 2, 2022. Furthermore, during the fiscal quarter ended April 4, 2021, the Ortho Board of Directors approved the share pool associated with our long-term equity incentive plan.

Underwritten Secondary Offering

In September 2021, we completed an underwritten secondary offering of 25.3 million ordinary shares held by a selling shareholder affiliated with Carlyle, including 3.3 million ordinary shares pursuant to the full exercise of the underwriters’ option to purchase additional shares. The ordinary shares sold in the secondary offering were registered under the Securities Act pursuant to a Registration Statement on Form S-1, which was declared effective by the SEC on September 9, 2021. We did not offer any ordinary shares in this transaction and did not receive any proceeds from the sale of the ordinary shares by the selling shareholder. We incurred costs of $1.1 million in relation to the secondary public offering for the fiscal year ended January 2, 2022, which were recorded in Selling, marketing and administrative expenses in our audited consolidated statement of operations.

Impact of the COVID-19 Pandemic

In response to the global COVID-19 pandemic, we mobilized our research and development teams to bring to market COVID-19 antibody and antigen tests. Our COVID-19 antibody tests detect whether a patient has been previously infected by COVID-19 and our COVID-19 antigen test detects whether a patient is currently infected by COVID-19. We have received a combination of EUA from the FDA, authority to affix a CE Mark for sale in the European Union and various other regulatory approvals globally for our COVID-19 antibody tests. We have also received authority to affix a CE Mark for sale in the European Union and the FDA accepted our EUA for our COVID-19 antigen test. We sell these tests in various other markets globally and continue to work on gaining further regulatory approvals in other markets. All of our COVID-19 antibody and antigen tests run on our existing instruments.

In February 2020, we began to see a decrease in the number of tests run in China. This decline spread to certain other countries in EMEA and ASPAC in early March 2020 and resulted in a worldwide decrease in the number of tests run globally by the end of that month. In many countries, we also experienced a lag between the timing of the decrease in the

199

number of tests run and the decrease in shipments of additional products to our customers, which began to occur during the fiscal quarter ended June 28, 2020. As a result, during the fiscal year ended January 3, 2021, we experienced decreased revenues and incurred idle or underutilized facilities costs, higher freight and higher distribution costs compared to the periods prior to the pandemic.

During the fiscal quarter ended January 3, 2021, we started to experience a recovery in the base business of our core revenue, which continued through the fiscal year ended January 2, 2022. Additionally, since the fiscal quarter ended June 28, 2020, our results of operations were supplemented with revenue from sales of our COVID-19 antibody and antigen tests. However, starting in the fiscal quarter ended July 4, 2021, this supplemental revenue from sales of our COVID-19 antibody and antigen tests began to decline and continued to decline into the fourth quarter of fiscal year 2021. During the fiscal year ended January 2, 2022, we also continued to experience higher distribution costs due to higher shipping rates as a result of the COVID-19 pandemic, and beginning in the fiscal quarter ended October 3, 2021, we experienced some supply chain disruptions. These supply chain disruptions have resulted in shortages or delays in receipts for certain key components of our instruments and assays. Additionally, we have experienced distribution challenges, which have affected our ability to fulfill customer orders on a timely basis, including instrument placements. These supply chain and distribution challenges have impacted, and we expect will continue to impact, our results of operations and resulted in disruption to our business operations. We are continuously evaluating our supply chain to identify potential gaps and take steps to ensure continuity, including working closely with our primary suppliers of these components and pursuing additional suppliers for certain of these components, in order to maintain supply to our customers. We continue to monitor the potential impact of these issues on our business.

We are continually monitoring our business continuity plans. Due to the fact that our products and services are considered to be medically critical, our manufacturing and research and development sites are generally exempt from governmental orders in the U.S. and other countries requiring businesses to cease or reduce operations. For these sites, we have implemented steps to protect our employees. Our office-based work sites in the U.S. are subject to operating restrictions consistent with applicable health guidelines. We permit limited domestic travel for our employees, which has reduced our travel-related operating expenses.

On September 9, 2021, President Biden issued the Executive Order on Ensuring Adequate COVID Safety Protocols for Federal Contractors (the “Executive Order”), which directs executive departments and agencies to ensure that contracts covered by the Executive Order require relevant federal contractors and subcontractors to mandate their employees to be fully vaccinated against COVID-19 by certain dates that continue to be extended by the government. The Executive Order has faced several legal challenges and on December 7, 2021, the U.S. District Court for the Southern District of Georgia issued a nationwide injunction blocking enforcement of the federal contractor mandate which was upheld by the Eleventh Circuit on December 17, 2021. We continue to monitor all court developments as well as impacts of requirements as it relates to any applicable contracts.

As the global COVID-19 pandemic is an ongoing matter, our future assessment of the magnitude and duration of the COVID-19 pandemic, as well as other factors, could result in material impacts to our consolidated financial statements in future reporting periods.

Results of Operations

Fiscal year ended January 2, 2022 compared with fiscal year ended January 3, 2021

Net loss

Net loss for the fiscal year ended January 2, 2022 was $54.3 million compared to net loss of $211.9 million for the fiscal year ended January 3, 2021, representing a decrease of $157.6 million. The decrease in net loss was primarily due to higher net revenue, primarily driven by growth of our base business, as well as a decrease in interest expense as a result of our debt pay down, and a decrease in other expense, primarily related to unrealized foreign currency losses in the prior year period. These impacts were partially offset by an increase in operating expenses, primarily Selling, marketing and administrative expenses.

Net revenue

Net revenue for the fiscal year ended January 2, 2022 increased by $276.6 million, or 15.7%, compared with the fiscal year ended January 3, 2021. Net revenue for the fiscal year ended January 2, 2022 included operational net revenue growth of 14.2% and a positive impact of 1.5% from foreign currency fluctuations, which was primarily driven by the weakening of the U.S. Dollar against a variety of currencies, primarily the Chinese Yuan, Euro and British Pound, partially offset by the

200

strengthening of the Japanese Yen and Brazilian Real. The increase in revenues for the fiscal year ended January 2, 2022, excluding the impact of foreign currency exchange, was mainly driven by our Core lines of business, as we recorded higher revenues across all geographic regions of our Clinical Laboratories and Transfusion Medicine businesses.

The following table shows total net revenue by line of business:

|  | Fiscal Year Ended |
(Dollars in millions) |  | January 2, 2022 |  |  | January 3, 2021 |  |  | % Change |
Clinical Laboratories |  | $ | 1,350.4 |  |  | $ | 1,154.2 |  |  |  | 17.0 | %
Transfusion Medicine |  |  | 664.3 |  |  |  | 580.6 |  |  |  | 14.4 | %
Core Revenue |  |  | 2,014.7 |  |  |  | 1,734.8 |  |  |  | 16.1 | %
Other Product Revenue |  |  | 6.2 |  |  |  | 8.5 |  |  |  | (26.9 | )%
Collaboration and Other Revenue |  |  | 21.9 |  |  |  | 22.9 |  |  |  | (4.4 | )%
Non-Core Revenue |  |  | 28.1 |  |  |  | 31.4 |  |  |  | (9.8 | )%
Net Revenue |  | $ | 2,042.8 |  |  | $ | 1,766.2 |  |  |  | 15.7 | %

Core revenue

Clinical Laboratories revenue for the fiscal year ended January 2, 2022 increased by $196.2 million, or 17.0%, compared with the fiscal year ended January 3, 2021, net of a decrease of $6.6 million from our COVID-19 antibody and antigen tests resulting from the deceleration of COVID-19 related testing year-over-year, primarily in the second half of the year. The increase included an operational net revenue growth of 15.4% and a positive impact of 1.6% from foreign currency fluctuations. The increase in Clinical Laboratories revenue was primarily due to higher reagent revenue, driven by the recovery of testing volumes in our base business and the growth of our installed base. The growth in the base business includes increases in revenues related to our chemistry slides and our wells, primarily our cardiac-related assays. Additionally, we recorded higher consumables and instrument sales across most regions, most notably in the Americas, and primarily related to our integrated clinical lab systems.

Transfusion Medicine revenue for the fiscal year ended January 2, 2022 increased by $83.7 million, or 14.4%, compared with the fiscal year ended January 3, 2021. This increase included operational net revenue growth of 13.1% and a positive impact of 1.3% from foreign currency fluctuations. The increase in Transfusion Medicine revenue, excluding the impact of foreign currency exchange, was primarily driven by strength in Donor Screening, including a new customer in our Donor Screening business in the United States, as well as an increase in Immunohematology assays.

Non-core revenue

Other product revenue, related to our contract manufacturing business, decreased by $2.3 million for the fiscal year ended January 2, 2022 compared with the fiscal year ended January 3, 2021, due to the timing of satisfying certain performance obligations related to a contract manufacturing arrangement in the current fiscal period.

Collaboration and other revenue for the fiscal year ended January 2, 2022 decreased by $1.0 million compared with the fiscal year ended January 3, 2021. The decrease was primarily due to lower revenues related to our HCV/HIV license agreements, partially offset by an $8.5 million award from an arbitration proceeding related to one of our collaboration agreements recorded during the current year period.

Cost of revenue

|  | Fiscal Year Ended |
(Dollars in millions) |  | January 2, 2022 |  |  | % of Net Revenue |  |  | January 3, 2021 |  |  | % of Net Revenue |
Cost of revenue |  | $ | 1,006.8 |  |  |  | 49.3 | % |  | $ | 908.2 |  |  |  | 51.4 | %

201

The increase in cost of revenue was primarily driven by the increase in revenues during the current year period. The decrease in cost of revenue as a percentage of net revenue for the fiscal year ended January 2, 2022 compared with the fiscal year ended January 3, 2021 was primarily due to lower manufacturing costs and lower underutilized facility costs, as well as the impact of the previously mentioned award from an arbitration proceeding related to one of our collaboration agreements, partially offset by higher freight costs and unfavorable product mix.

Operating expenses

The following table provides a summary of certain operating expenses:

|  | Fiscal Year Ended |
(Dollars in millions) |  | January 2, 2022 |  |  | % of Net Revenue |  |  | January 3, 2021 |  |  | % of Net Revenue |
Selling, marketing and administrative expenses |  | $ | 555.0 |  |  |  | 27.2 | % |  | $ | 489.6 |  |  |  | 27.7 | %
Research and development expense |  |  | 126.2 |  |  |  | 6.2 | % |  |  | 112.9 |  |  |  | 6.4 | %
Amortization of intangible assets |  |  | 133.4 |  |  |  | 6.5 | % |  |  | 131.9 |  |  |  | 7.5 | %
Other operating expense, net |  |  | 47.5 |  |  |  | 2.3 | % |  |  | 35.3 |  |  |  | 2.0 | %

Selling, marketing and administrative expenses

Selling, marketing and administrative expenses were $555.0 million for the fiscal year ended January 2, 2022, or 27.2% of net revenue, as compared with $489.6 million for the fiscal year ended January 3, 2021, or 27.7% of net revenue, an increase of $65.4 million. The increase in selling, marketing and administrative expenses was primarily due to higher employee-related costs, including stock-based compensation, and increased distribution costs due to higher shipment volumes and higher shipping rates as a result of the ongoing global COVID-19 pandemic.

Research and development expense

Research and development expense was $126.2 million for the fiscal year ended January 2, 2022, or 6.2% of net revenue, as compared with $112.9 million for the fiscal year ended January 3, 2021, or 6.4% of net revenue, an increase of $13.3 million. The increase was primarily due to an increased investment in costs to develop new assays, as well as an increase in employee-related costs, partially offset by the $7.5 million up-front payment made to Quotient in the prior year period.

Amortization of intangible assets

Amortization of intangible assets was $133.4 million for the fiscal year ended January 2, 2022 as compared with $131.9 million for the fiscal year ended January 3, 2021. There were no significant changes in the composition of our intangible assets in the fiscal year ended January 2, 2022 compared to the fiscal year ended January 3, 2021.

Other operating expense, net

Other operating expense, net, was $47.5 million, or 2.3% of net revenue, for the fiscal year ended January 2, 2022, as compared with $35.3 million, or 2.0% of net revenue, for the fiscal year ended January 3, 2021, an increase of $12.2 million. The increase was primarily due to costs incurred of $7.0 million related to the acquisition of Ortho by Quidel and, to a lesser extent, higher profit share expense in the current year due to lower manufacturing costs related to our Joint Business.

Non-operating items

Interest expense, net

Interest expense, net was $146.0 million for the fiscal year ended January 2, 2022, compared with $198.2 million for the fiscal year ended January 3, 2021. The decrease of $52.2 million was primarily related to lower borrowings due to the use of the net proceeds from the IPO to (i) redeem $160.0 million of our 2025 Notes, (ii) redeem $270.0 million of our 2028 Notes, and (iii) repay $892.7 million in aggregate principal amount of borrowings under our Dollar Term Loan Facility.

202

Tax indemnification expense, net

Tax indemnification expense was $0.8 million for the fiscal year ended January 2, 2022, and was primarily related to the release of certain pre-acquisition U.S. state tax reserves. Tax indemnification expense was $31.2 million for the fiscal year ended January 3, 2021, and was primarily related to the release of certain tax reserves upon the settlement of certain U.S. federal and state tax matters, with an offsetting benefit recorded to income tax expense.

Other expense, net

Other expense, net was $53.1 million for the fiscal year ended January 2, 2022 and was comprised primarily of loss on early extinguishment of debt of $50.3 million, which was related to the use of proceeds from the IPO to redeem portions of our outstanding 2025 Notes, 2028 Notes and Dollar Term Loan Facility.

Other expense, net was $84.2 million for the fiscal year ended January 3, 2021 and primarily related to $69.5 million of foreign currency losses, of which $68.2 million was unrealized, and loss on early extinguishment of the 2022 Notes of $12.6 million. The unrealized foreign currency losses are mainly related to intercompany loans denominated in currencies other than the functional currency of the affected subsidiaries.

Provision for (benefit from) income taxes

During the fiscal year ended January 2, 2022, we incurred a loss before provision for income taxes of $26.0 million and recognized a provision for income taxes of $28.3 million, resulting in a negative effective tax rate of 109.0%. The effective tax rate differs from the U.S. federal statutory rate primarily due to (i) a net cost of $44.7 million for the impacts of operating losses in certain subsidiaries not being benefited due to the establishment of valuation allowances, (ii) a net benefit of $23.8 million related to non-U.S. earnings being taxed at rates that are different than the U.S. statutory rate, and (iii) a net cost of $11.8 million for the tax expense associated with the remeasurement of deferred tax assets and liabilities due to the enactment of new tax rates, primarily in the United Kingdom.

During the fiscal year ended January 3, 2021, we incurred a loss before benefit from income taxes of $225.3 million and recognized a benefit from income taxes of $13.4 million resulting in an effective tax rate of 5.9%. The effective tax rate for each period differs from the U.S. federal statutory rate primarily due to (i) a net cost of $63.8 million for the impacts of operating losses in certain subsidiaries not being benefited due to the establishment of a valuation allowance, (ii) a net benefit of $37.3 million related to a decrease in our pre-Acquisition reserves for uncertain tax positions due to the settlement of certain tax matters, (iii) partially offset by a net cost of $5.7 million related to an increase in certain post-Acquisition non-U.S. reserves for uncertain tax positions and (iv) a net benefit of $23.1 million for non-U.S. earnings being taxed at rates that are different than the U.S. statutory rate.

Fiscal year ended January 3, 2021 compared with fiscal year ended December 29, 2019

Overview of results

During the fiscal year ended January 3, 2021, reported net loss of $211.9 million increased by $55.0 million compared with the fiscal year ended December 29, 2019. Our results were materially impacted by the global COVID-19 pandemic, as net revenue for the fiscal year ended January 3, 2021 decreased by $35.3 million compared with the fiscal year ended December 29, 2019. This decrease included operational net revenue declines of 1.3% and a negative impact of 0.7% from foreign currency fluctuations. We also incurred higher idle or underutilized facilities costs, higher freight costs and higher distribution costs, which were partially offset by cost containment measures to incur lower employee-related costs and lower travel-related costs. Our results were also affected by a research and development upfront payment of $7.5 million, higher foreign currency losses, primarily unrealized, and losses on early extinguishment of our 2022 Notes, partially offset by lower interest expense.

Net revenue

Net revenue for the fiscal year ended January 3, 2021 decreased by $35.3 million, or 2.0%, compared with the fiscal year ended December 29, 2019. Net revenue for the fiscal year ended January 3, 2021 included operational net revenue declines of 1.3% and a negative impact of 0.7% from foreign currency fluctuations, which was primarily driven by the strengthening of the U.S. dollar against a variety of currencies. The decrease in net revenue for the fiscal year ended January 3, 2021,

203

excluding the impact of foreign currency exchange, was mainly driven by lower revenues in our Clinical Laboratories business in the EMEA, Greater China and other regions due primarily to the global COVID-19 pandemic and lower local HCV revenue in the Japan region of approximately $18 million, as well as lower revenues in our Transfusion Medicine business in all regions due primarily to the global COVID-19 pandemic. These decreases were partially offset by increases in our Clinical Laboratories business in the North America region related to sales of our COVID-19 antibody tests and other assays, instrument sales and grant revenue related to development of our COVID-19 antibody and antigen tests. The decrease in net revenue was also impacted by lower Other Product Revenue due to the reduction and timing of certain performance obligations in a contract manufacturing arrangement.

The following table shows total net revenue by line of business:

|  | Fiscal year ended |
($ in millions) |  | January 3, 2021 |  |  | December 29, 2019 |  |  | % Change |

Net Revenue |  | $ | 1,766.2 |  |  | $ | 1,801.5 |  |  |  | (2.0 | )%

Core revenue

Clinical Laboratories revenue for the fiscal year ended January 3, 2021 increased by $11.9 million, or 1.0%, compared with the fiscal year ended December 29, 2019. This increase included operational net revenue gains of 2.3% partially offset by a negative impact of 1.2% from foreign currency fluctuations. Clinical Laboratories revenue increased in the North America region related to sales of our COVID-19 antibody tests and other assays, instrument sales and grant revenue related to development of our COVID-19 antibody and antigen tests. These increases were offset by lower revenues in the EMEA, Greater China and other regions due primarily to decreased shipments to customers as a result of the global COVID-19 pandemic and lower local HCV revenue in the Japan region of approximately $18 million.

Transfusion Medicine revenue for the fiscal year ended January 3, 2021 decreased by $17.4 million, or 2.9%, compared with the fiscal year ended December 29, 2019. This decrease included operational net revenue declines of 3.3% partially offset by a positive impact of 0.3% from foreign currency fluctuations. The decrease in Transfusion Medicine revenue was primarily due to decreased shipments to customers in all regions as a result of the global COVID-19 pandemic.

Non-core revenue

Other Product Revenue for the fiscal year ended January 3, 2021 decreased by $28.8 million, or 77.2%, compared with the fiscal year ended December 29, 2019. The decrease was due to the reduction and timing of certain performance obligations in a contract manufacturing arrangement.

Collaboration and Other Revenue for the fiscal year ended January 3, 2021 decreased by $1.0 million, or 4.2%, compared with the fiscal year ended December 29, 2019. The decrease was primarily due to lower revenues related to our HCV/HIV license agreements, partially offset by $7.5 million of license revenue related to the Joint Business granting a customer a license to sell certain products in Canada.

Cost of revenue

|  | Fiscal year ended |
($ in millions) |  | January 3, 2021 |  |  | % of Net Revenue |  |  | December 29, 2019 |  |  | % of Net Revenue |
Cost of revenue |  | $ | 908.2 |  |  |  | 51.4 | % |  | $ | 922.4 |  |  |  | 51.2 | %

204

The increase in cost of revenue, and as a percentage of net revenue for the fiscal year ended January 3, 2021 compared with the fiscal year ended December 29, 2019, was primarily due to idle or underutilized facility costs of $14.8 million and freight costs of $6.9 million incurred as a result of the global COVID-19 pandemic. This increase was partially offset by $11.0 million of lower restructuring costs in the fiscal year ended January 3, 2021 compared with the fiscal year ended December 29, 2019, which were primarily related to depreciation related charges incurred in the fiscal year ended December 29, 2019 related to assets no longer in use due to the transfer of certain production lines. See “ Restructuring Activities.”

Operating expenses

The following table provides a summary of certain operating expenses:

|  | Fiscal year ended |
($ in millions) |  | January 3, 2021 |  |  | % of Net Revenue |  |  | December 29, 2019 |  |  | % of Net Revenue |

Other operating expense, net |  |  | 35.3 |  |  |  | 2.0 | % |  |  | 48.8 |  |  |  | 2.7 | %

Selling, marketing and administrative expenses

Selling, marketing and administrative expenses were $489.6 million for the fiscal year ended January 3, 2021, or 27.7% of net revenue, as compared with $515.1 million for the fiscal year ended December 29, 2019, or 28.6% of net revenue, a decrease of $25.5 million. The decrease in selling, marketing and administrative expenses was primarily due to decreased employee-related costs, including stock-based compensation and severance expense, and decreased travel-related costs, partially offset by increased distribution costs and increased third-party costs.

Research and development expense

Research and development expense was $112.9 million for the fiscal year ended January 3, 2021, or 6.4% of net revenue, as compared with research and development expense of $98.0 million for the fiscal year ended December 29, 2019, or 5.4% of net revenue, an increase of $14.9 million. The increase was primarily due to a research and development upfront payment of $7.5 million made to Quotient upon the signing of a binding letter agreement and costs incurred to perform research and development activities related to developing our COVID-19 antibody and antigen tests.

Amortization of intangible assets

Amortization of intangible assets was $131.9 million for the fiscal year ended January 3, 2021 as compared with $131.7 million for the fiscal year ended December 29, 2019. There were no major changes in the composition of our intangible assets in the fiscal year ended January 3, 2021 compared to the fiscal year ended December 29, 2019.

Other operating expense, net

Other operating expense, net, was $35.3 million, or 2.0% of net revenue, for the fiscal year ended January 3, 2021, as compared with $48.8 million, or 2.7% of net revenue, for the fiscal year ended December 29, 2019, a decrease of $13.5 million. The decrease was primarily due to lower profit share expense in the current year from lower revenue related to our Joint Business.

Non-operating items

Interest expense, net

Interest expense was $198.2 million for the fiscal year ended January 3, 2021, compared with $231.4 million for the fiscal year ended December 29, 2019. The decrease of $33.2 million was primarily related to lower interest rates on the Dollar Term Loan Facility.

205

Tax indemnification expense, net

Tax indemnification expense was $31.2 million for the fiscal year ended January 3, 2021, and was primarily related to the release of certain tax reserves upon the settlement of certain U.S. federal and state tax matters, with an offsetting benefit recorded to income tax expense. Tax indemnification expense was $29.2 million for the fiscal year ended December 29, 2019, and was primarily related to the release of certain tax reserves upon the settlement of certain state tax matters, with an offsetting benefit recorded to income tax expense.

Other expense, net

Other expense, net was $84.2 million for the fiscal year ended January 3, 2021 and primarily related to $69.5 million of foreign currency losses, of which $68.2 million was unrealized and loss on early extinguishment of the 2022 Notes of $12.6 million. The unrealized foreign currency losses are mainly related to intercompany loans denominated in currencies other than the functional currency of the affected subsidiaries.

Other expense, net was $5.7 million for the fiscal year ended December 29, 2019 and primarily related to $16.0 million of fair value losses on interest rate caps that did not qualify for hedge accounting, partially offset by $10.5 million of net foreign currency gains, of which $18.1 million was unrealized. The unrealized foreign currency gains are mainly related to intercompany loans denominated in currencies other than the functional currency of the affected subsidiaries.

Benefit from income taxes

During the fiscal year ended January 3, 2021, we incurred a loss before benefit from income taxes of $225.3 million and recognized a benefit from income taxes of $13.4 million resulting in an effective tax rate of 5.9%. The effective tax rate differs from the U.S. federal statutory rate primarily due to (1) the impact of operating losses in certain subsidiaries not being benefited due to the establishment of a valuation allowance (2) a decrease in our pre-Acquisition reserves for uncertain tax positions due to the settlement of certain tax matters, (3) partially offset by an increase in certain post-Acquisition non-U.S. reserves for uncertain tax positions and (4) non-U.S. earnings being taxed at rates that are different than the U.S. statutory rate.

During the fiscal year ended December 29, 2019, we incurred a loss before benefit from income taxes of $180.8 million and recognized a benefit from income taxes of $23.9 million resulting in an effective tax rate of 13.3%. The effective tax rate for each period differs from the U.S. federal statutory rate primarily due to (1) the impact of operating losses in certain subsidiaries not being benefited due to the establishment of a valuation allowance, (2) a decrease in our pre-Acquisition state and non-U.S. reserves for uncertain tax positions due to the settlement of certain tax matters, (3) an increase in our interest expense on prior year reserves for uncertain tax positions and (4) non-U.S. earnings being taxed at rates that are different than the U.S. statutory rate.

Use of Non-GAAP Financial Measures

Reconciliation of Net Loss to Adjusted EBITDA

We believe that our financial statements and the other financial data included in this joint proxy statement/prospectus have been prepared in a manner that complies, in all material respects, with GAAP, and are consistent with current practice, with the exception of the inclusion of financial measures that differ from measures calculated in accordance with GAAP, including Adjusted EBITDA and Management EBITDA. Adjusted EBITDA consists of net loss before interest expense, net provision for (benefit from) income taxes and depreciation and amortization and eliminates (i) certain non-operating income or expense, and (ii) impacts of certain noncash, unusual or other items that are included in net loss that we do not consider indicative of our ongoing operating performance. Management EBITDA consists of Adjusted EBITDA plus certain other management adjustments.

We use these financial measures in the analysis of our financial and operating performance because they assist in the evaluation of underlying trends in our business. Additionally, prior to fiscal year 2021, we used Management EBITDA in assessing the profitability of our geographic-based reportable segments and as a basis for calculating certain management incentive compensation programs. Effective January 4, 2021, we changed the basis by which we measure segment profitability to Adjusted EBITDA. In the case of Adjusted EBITDA and Management EBITDA, we believe that making such adjustments provides management and investors meaningful information to understand our operating performance and ability to analyze financial and business trends on a period-to-period basis. We believe that the presentation of these financial measures enhances an investor’s understanding of our financial performance. We use certain of these financial measures for business planning purposes and measuring our performance relative to that of our competitors.

Other companies in our industry may calculate Adjusted EBITDA and Management EBITDA differently than we do. As a result, these financial measures have limitations as analytical and comparative tools and you should not consider these items in isolation, or as a substitute for analysis of our results as reported under GAAP. Adjusted EBITDA and Management EBITDA should not be considered as measures of discretionary cash available to us to invest in the growth of our business. In calculating these financial measures, we make certain adjustments that are based on assumptions and estimates that may prove to have been inaccurate. In addition, in evaluating these financial measures, you should be aware that in the future we may incur expenses similar to those eliminated in the presentation of these metrics included in this joint proxy statement/prospectus. Our presentation of Adjusted EBITDA and Management EBITDA should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items or changes in our customer base. Additionally, our presentation of Adjusted EBITDA may differ from that included in the Credit Agreement, the 2025 Notes Indenture and the 2028 Notes Indenture for purposes of covenant calculation.

Adjusted EBITDA and Management EBITDA have important limitations as an analytical tool and you should not consider it in isolation or as substitutes for analysis of our results as reported under GAAP. Some of these limitations include the fact that Adjusted EBITDA and Management EBITDA:

| • |  | do not reflect the significant interest expense on our debt, including the Senior Secured Credit Facilities, the 2025 Notes and the 2028 Notes;

| • |  | eliminate the impact of income taxes on our results of operations; and

| • |  | do not reflect any cash requirements for any future replacements of assets being depreciated and amortized, although the assets being depreciated and amortized will often have to be replaced in the future.

We compensate for these limitations by relying primarily on our GAAP results and using these financial measures only as a supplement to our GAAP results.

The following tables reconcile Net loss to Adjusted EBITDA for fiscal years ended January 2, 2022 and January 3, 2021:

Segment Results

Fiscal year ended January 2, 2022 compared with fiscal year ended January 3, 2021

The key indicators that we monitor are as follows:

| • |  | Net revenue—This measure is discussed in the section entitled “Results of Operations.”

| • |  | Adjusted EBITDA—Adjusted EBITDA by reportable segment is used by our management to measure and evaluate the internal operating performance of our segments. It is also the basis for calculating certain management incentive compensation programs. We believe that this measurement is useful to investors as a way to analyze the underlying trends in our core business, including at the segment level, consistently across the periods presented and also to evaluate performance under management incentive compensation programs. In fiscal year 2021, we changed the basis by which we measure segment profit or loss from Management EBITDA to Adjusted EBITDA. The new basis has been retroactively applied to the prior year comparable period presented.

Americas

Net revenue was $1,228.9 million for the fiscal year ended January 2, 2022 compared to net revenue of $1,067.3 million for the fiscal year ended January 3, 2021, including a decrease in sales of $10.0 million from our COVID-19 antibody and antigen tests. The increase of $161.6 million, or 15.1%, which included operational net revenue growth of 14.8% and a positive impact of 0.4% from foreign currency fluctuations, was primarily due to higher reagent and instrument revenues in our Clinical Laboratories business, a new customer in our Donor Screening business in the United States, grant revenue related to development of our COVID-19 antibody and antigen tests and an $8.5 million award from an arbitration proceeding related to one of our collaboration agreements.

Adjusted EBITDA was $516.6 million for the fiscal year ended January 2, 2022 compared to Adjusted EBITDA of $463.1 million for the fiscal year ended January 3, 2021. The increase of $53.5 million, or 11.6%, was primarily due to higher revenues, partially offset by increased employee-related costs.

EMEA

Net revenue was $276.3 million for the fiscal year ended January 2, 2022 compared to net revenue of $240.6 million for the fiscal year ended January 3, 2021, including incremental sales of $4.6 million from our COVID-19 antibody and antigen tests. The increase of $35.7 million, or 14.8%, which included operational net revenue growth of 11.5% and a positive impact of 3.4% from foreign currency fluctuations, was primarily due to higher reagent revenue and, to a lesser extent, instrument sales in our Clinical Laboratories business, and higher reagent revenue in our Immunohematology business.

Adjusted EBITDA was $63.9 million for the fiscal year ended January 2, 2022 compared to Adjusted EBITDA of $41.9 million for the fiscal year ended January 3, 2021. The increase of $22.0 million, or 52.4%, was primarily due to higher revenues, partially offset by increased employee-related costs.

Greater China

Net revenue was $274.4 million for the fiscal year ended January 2, 2022 compared to net revenue of $229.6 million for the fiscal year ended January 3, 2021. The increase of $44.8 million, or 19.5%, which included operational net revenue growth of 12.3% and a positive impact of 7.2% from foreign currency fluctuations, was primarily due to higher reagent revenue in both our Clinical Laboratories and Immunohematology businesses, partially offset by lower instrument sales in our Clinical Laboratories business.

Adjusted EBITDA was $129.2 million for the fiscal year ended January 2, 2022 compared to Adjusted EBITDA of $108.0 million for the fiscal year ended January 3, 2021. The increase of $21.2 million, or 19.7%, was primarily due to higher revenues, partially offset by increased employee-related costs and government subsidies received in the prior year period.

Other

Net revenue was $263.2 million for the fiscal year ended January 2, 2022 compared to net revenue of $228.7 million for the fiscal year ended January 3, 2021. The increase of $34.5 million, or 15.1%, which included operational net revenue growth of 16.2% and a negative impact of 1.1% from foreign currency fluctuations, was primarily due to higher reagent revenue in our Clinical Laboratories and Transfusion Medicine businesses.

Adjusted EBITDA was $79.9 million for the fiscal year ended January 2, 2022 compared to Adjusted EBITDA of $65.9 million for the fiscal year ended January 3, 2021. The increase of $14.0 million, or 21.3%, was primarily due to higher revenues, partially offset by increased employee-related and distribution costs.

Fiscal year ended January 3, 2021 compared with fiscal year ended December 29, 2019

The key indicators that we monitored were as follows:

| • |  | Net revenue—This measure is discussed in the section entitled “Results of Operations.”

| • |  | Management EBITDA—Management EBITDA by reportable segment was used by our management to measure and evaluate the internal operating performance of our segments. It was also the basis for calculating certain

210

| management incentive compensation programs. Management EBITDA was our Adjusted EBITDA further adjusted for other items including realized foreign currency gains and losses, impact from adoption of accounting standards, costs in connection with COVID-19 and other immaterial management adjustments. We believe that this measurement was useful to investors as a way to analyze the underlying trends in our core business, including at the segment level, consistently across the periods presented and also to evaluate performance under management incentive compensation programs. Effective January 4, 2021, we changed our basis for which we measure segment profit or loss from Management EBITDA to Adjusted EBITDA. However, it is impracticable for us to retroactively recast our segment results for fiscal year 2019. Accordingly, fiscal year 2020 and 2019 segment results have been presented below on our former profit or loss basis for comparability.

Americas

Net revenue was $1,067.3 million for the fiscal year ended January 3, 2021 compared to net revenue of $1,042.5 million for the fiscal year ended December 29, 2019. The increase of $24.8 million, or 2.4%, which included operational net revenue growth of 4.1% partially offset by a negative impact of 1.7% from foreign currency fluctuations, was primarily due to higher Clinical Laboratories revenue in the North America region related to sales of our COVID-19 antibody tests and other assays, instrument sales and grant revenue related to development of our COVID-19 antibody and antigen tests. These increases were partially offset by decreased shipments to customers in the North America region in the Transfusion Medicine business and in the LATAM region for both the Clinical Laboratories and Transfusion Medicine businesses as a result of the global COVID-19 pandemic.

Management EBITDA was $486.8 million for the fiscal year ended January 3, 2021 compared to Management EBITDA of $418.4 million for the fiscal year ended December 29, 2019. The increase of $68.4 million, or 16.3%, was primarily due to higher revenues in the North America region, lower employee-related costs and lower travel-related costs.

EMEA

Net revenue was $240.6 million for the fiscal year ended January 3, 2021 compared to net revenue of $251.5 million for the fiscal year ended December 29, 2019.

Greater China

Net revenue was $229.6 million for the fiscal year ended January 3, 2021 compared to net revenue of $242.5 million for the fiscal year ended December 29, 2019. The decrease of $12.9 million, or 5.3%, which included operational net revenue declines of 6.0% partially offset by a positive impact of 0.7% from foreign currency fluctuations, was primarily due to decreased shipments to customers as a result of the global COVID-19 pandemic.

Management EBITDA was $107.3 million for the fiscal year ended January 3, 2021 compared to Management EBITDA of $118.4 million for the fiscal year ended December 29, 2019. The decrease of $11.1 million, or 9.4%, was primarily due to decreased shipments to customers as a result of the global COVID-19 pandemic, partially offset by lower travel-related costs.

Other

Net revenue was $228.7 million for the fiscal year ended January 3, 2021 compared to net revenue of $265.0 million for the fiscal year ended December 29, 2019. The decrease of $36.3 million, or 13.7%, which included operational net revenue declines of 14.0% partially offset by a positive impact of 0.3% from foreign currency fluctuations, was primarily due to decreased shipments to customers as a result of the global COVID-19 pandemic as well as the lower revenue related to a supply agreement in our HCV business in the Japan region.

Management EBITDA was $73.5 million for the fiscal year ended January 3, 2021 compared to Management EBITDA of $88.8 million for the fiscal year ended December 29, 2019. The decrease of $15.3 million, or 17.2%, was primarily due to decreased shipments to customers as a result of the global COVID-19 pandemic as well as lower revenue related to a supply agreement in our HCV business in the Japan region, partially offset by lower employee-related costs.

Liquidity and Capital Resources

As of January 2, 2022 and January 3, 2021, we had $309.7 million and $132.8 million of Cash and cash equivalents, respectively. As of January 2, 2022 and January 3, 2021, $157.5 million and $108.8 million, respectively, of these Cash and cash equivalents were maintained in non-U.S. jurisdictions, primarily held in foreign currencies. We believe our organizational structure allows us the necessary flexibility to move funds throughout our subsidiaries to meet our operational working capital needs.

Notwithstanding the foregoing, until the Quidel Effective Time (as defined in the Business Combination Agreement) or termination of the Business Combination Agreement in accordance with its terms, subject to certain specified exceptions, we are subject to a variety of restrictions as specified under the Business Combination Agreement. Unless Quidel approves in writing (which approval will not be unreasonably withheld, conditioned or delayed, subject to certain exceptions), we may not, among other things, engage in another merger, restructuring or reorganization; incur indebtedness for borrowed money or issued debt securities, except for borrowing in amounts not to exceed $25 million in the aggregate (including pursuant to drawdowns of credit facilities outstanding on the date of the Business Combination Agreement) (excluding with respect to financing required in order to consummate the Combinations); or lease, license, transfer, exchange or swap, mortgage, pledge, abandon, allow to lapse or otherwise dispose of any of our assets, except for dispositions individually or in the aggregate that have a fair market value of less than $25 million, transactions between us and any of our subsidiaries, or in the ordinary course of business.

Fiscal year ended January 2, 2022

Net cash flows provided by operating activities

Net cash provided by operating activities was $286.6 million for the fiscal year ended January 2, 2022. Factors resulting in Cash provided by operating activities included strong collections on Accounts receivable, as well as the impact of our new receivables purchase agreement, cash inflows from earnings before interest, taxes, depreciation and amortization expense, and increase Accounts payable and accrued expenses. These increases were partially offset by the payment of interest on borrowings of $132.1 million and increased investments in inventories of $139.5 million, which includes $106.3 million of instrument inventories that were transferred from Inventories to Property, plant and equipment, net, related to customer leased instruments.

Net cash flows used in investing activities

Net cash used in investing activities was $43.6 million for the fiscal year ended January 2, 2022. The primary factor resulting in Cash used in investing activities was Purchases of property, plant and equipment during the fiscal year ended January 2, 2022 of $58.4 million, partially offset by proceeds of $15.2 million related to the net settlement of our terminated cross currency swaps.

Net cash flows used in financing activities

Net cash used in financing activities was $74.7 million for the fiscal year ended January 2, 2022. During the fiscal year ended January 2, 2022, payments on long-term borrowings of $1,423.0 million and payments on short-term borrowings, net of $82.0 million, including the repayment of the outstanding balance of our Financing Program, were partially offset by net proceeds from our initial public offering of $1,426.4 million.

Fiscal year ended January 3, 2021

Net cash flows provided by operating activities

Net cash provided by operating activities was $46.1 million for the fiscal year ended January 3, 2021. Factors resulting in cash provided by operating activities included cash inflows from earnings before interest, taxes, depreciation and amortization expense and other noncash items and lower accounts receivable of $33.3 million, partially offset by interest paid on borrowings of $191.8 million, net investment in inventories of $152.0 million, which includes $132.3 million of instrument inventories that were transferred from “Inventories” to “Property, plant and equipment, net”. Net cash provided by operating activities for fiscal year 2020 decreased $96.9 million compared to fiscal year 2019 primarily due to the impact of the global pandemic.

Net cash flows used in investing activities

Purchases of property, plant and equipment during the fiscal year ended January 3, 2021 were $44.1 million.

In addition to the capital expenditures of $44.1 million, we made noncash transfers of $132.3 million of instrument inventories from “Inventories” to “Property, plant and equipment, net” further increasing our investment in property, plant and equipment.

Net cash flows provided by financing activities

During the fiscal year ended January 3, 2021, net proceeds from the issuance of the 2025 Notes, 2028 Notes and Euro Term Loan Facility of $1,421.0 million were offset by payments on the 2022 Notes of $1,363.5 million. Net payments on short-term borrowings were $3.5 million.

Fiscal year ended December 29, 2019

Net cash flows provided by operating activities

Net cash provided by operating activities was $143.0 million for the fiscal year ended December 29, 2019. Factors resulting in cash provided by operating activities included cash inflows from earnings before interest, taxes, depreciation and

As of January 2, 2022 and January 3, 2021, there were no outstanding borrowings under the Revolving Credit Facility. As of January 2, 2022 and January 3, 2021, letters of credit issued under the Revolving Credit Facility totaled $46.3 million and $37.5 million, respectively, which reduced the availability under the Revolving Credit Facility. Availability under the Revolving Credit Facility was $453.7 million and $312.5 million as of January 2, 2022 and January 3, 2021, respectively. Our debt agreements contain various covenants that may restrict our ability to borrow on available credit facilities and future financing arrangements or require us to remain below a specific credit coverage threshold. We believe that we are and will continue to be in compliance with these covenants.

On February 5, 2021, we entered into a fifth amendment to the Credit Agreement, which increased the Revolving Credit Facility contained in the credit agreement by $150 million to an aggregate amount of $500 million and extended the maturity date to February 5, 2026, provided that such date may be accelerated subject to certain circumstances as set forth in the fifth amendment. To the extent that the aggregate principal amount of the Dollar Term Loan Facility and Euro Term Loan Facility (and any Refinancing Indebtedness (as defined in the Credit Agreement) with respect thereto that matures on or prior to June 30, 2025) outstanding as of March 31, 2025 exceeds $500 million then the maturity date with respect to the Revolving Credit Facility shall be March 31, 2025.

214

On December 24, 2021, we entered into a sixth amendment to the Senior Secured Credit Facilities to account for the cessation of LIBOR for Sterling, Euros and Japanese Yen and the alternative replacement rates with respect to such currencies, as applicable. All other terms of the Senior Secured Credit Facilities remain substantially the same except as otherwise amended by the fifth and sixth amendments.

On February 5, 2021 and February 9, 2021, we used a portion of the proceeds from the Ortho IPO to repay $706.6 million and $186.1 million, respectively, of borrowings under the Dollar Term Loan Facility. In aggregate, we repaid $892.7 million of borrowings under the Dollar Term Loan Facility.

As of January 2, 2022 and January 3, 2021, the remaining balance of deferred financing costs related to the Dollar Term Loan Facility was $8.1 million and $17.3 million, respectively. As of January 2, 2022 and January 3, 2021, the remaining balance of deferred financing costs related to the Euro Term Loan Facility was $3.6 million and $4.6 million, respectively. As of January 2, 2022 and January 3, 2021, the remaining unamortized balance related to the Revolving Credit Facility was $2.7 million and $3.4 million, respectively. The effective interest rate of the Term Loan as of January 2, 2022 is 5.74%.

On January 27, 2020, we issued $675 million aggregate principal amount of the 2028 Notes, which bear interest at a rate of 7.250% per annum payable semi-annually in arrears on February 1 and August 1 of each year. The 2028 Notes will mature on February 1, 2028. The 2028 Notes and guarantees thereof are our senior unsecured obligations and the 2028 Notes and the guarantees rank equally in right of payment with all of the Lux Co-Issuer’s and U.S. Co-Issuer’s (together, the “Issuers”) and guarantors’ existing and future senior debt, including the 2025 Notes. The 2028 Notes and the guarantees thereof are effectively subordinated to any of the Issuers’ and guarantors’ existing and future secured debt, including the Senior Secured Credit Facilities, to the extent of the value of the assets securing such debt. In addition, the 2028 Notes and the guarantees thereof rank senior in right of payment to all of the Issuers’ and guarantors’ future subordinated debt and will be structurally subordinated to the liabilities of our non-guarantor subsidiaries. We incurred deferred financing costs of $12.9 million related to the 2028 Notes, which were capitalized as deferred financing costs and are being amortized using the effective interest method as a component of interest expense over the life of the 2028 Notes. On February 5, 2021, we used a portion of the proceeds from the Ortho IPO to redeem $270 million aggregate principal amount of the 2028 Notes, plus accrued interest thereon and $19.6 million of redemption premium. The redemption resulted in an extinguishment loss recognized of $24.3 million during the fiscal year ended January 2, 2022, which consisted of $4.7 million of unamortized deferred issuance costs and $19.6 million of redemption premium.

Concurrent with the issuance of the 2028 Notes, we entered into a $350 million U.S. dollar equivalent swap to Japanese Yen-denominated interest at a weighted average rate of 5.56%, for a five-year term. We terminated the cross currency swaps on April 1, 2021 and received $12.8 million of cash from net settlement in the year ended January 2, 2022.

On June 11, 2020, we issued $400 million aggregate principal amount of the 2025 Notes, which bear interest at a rate of 7.375% per annum, payable semi-annually in arrears on June 1 and December 1 of each year. The 2025 Notes will mature on June 1, 2025. The 2025 Notes and the guarantees thereof are our unsecured obligations and the 2025 Notes and the guarantees thereof rank equally in right of payment with all of the Issuers’ and guarantors’ existing and future senior debt, including the 2028 Notes. The 2025 Notes and the guarantees thereof are effectively subordinated to any of the Issuers’ and guarantors’ existing and future secured debt, including the Senior Secured Credit Facilities, to the extent of the value of the assets securing such debt. In addition, the 2025 Notes and the guarantees thereof rank senior in right of payment to all of the Issuers’ and guarantors’ future subordinated debt and will be structurally subordinated to the liabilities of the Issuers’ non-guarantor subsidiaries. We incurred deferred financing costs of $7.5 million related to the 2025 Notes, which were capitalized as deferred financing costs and are being amortized using the effective interest method as a component of interest expense over the life of the 2025 Notes. On February 5, 2021, we used a portion of the proceeds from the Ortho IPO to redeem $160 million aggregate principal amount of the 2025 Notes, plus accrued interest thereon and $11.8 million of redemption premium. The redemption resulted in an extinguishment loss recognized of $14.5 million for the fiscal year ended January 2, 2022, which consisted of $2.7 million of unamortized deferred issuance costs and $11.8 million of redemption premium.

In September 2016, we entered into an accounts receivable financing program (the “Financing Program”) with a financial institution. The Financing Program, which was fully paid off in June 2021 in connection with entry into the RPA (as defined below), was set to mature on January 24, 2022 and was secured by receivables from our U.S. business that are sold or contributed to a wholly owned, consolidated, bankruptcy remote subsidiary. The bankruptcy remote subsidiary’s sole business consists of the purchase or receipt of the receivables and subsequent granting of a security interest to the financial

215

institution under the program, and its assets were available first to satisfy obligations and were not available to pay creditors of our other legal entities. Under the Financing Program, we could borrow up to the lower of $75.0 million or 85% of the accounts receivable borrowing base. Interest on outstanding borrowings under the Financing Program was charged based on a per annum rate equal to the London Inter-bank Offered Rate (the “LIBOR Rate”) (with a floor of zero percent and as defined in the agreement) plus the LIBOR Rate margin (2.25 percentage points) if the related loan was a LIBOR Rate loan. Otherwise, the per annum rate was equal to a Base Rate (as defined in the Financing Program agreement) plus the base rate margin (1.25 percentage points). Interest was due and payable, in arrears, on the first day of each month. The Financing Program was also subject to termination under standard events of default as defined.

On June 11, 2021, Ortho-Clinical Diagnostics FinanceCo I, LLC (“Ortho FinanceCo I”), a wholly owned receivables financing subsidiary of us, entered into a receivables purchase agreement (the “RPA”) with Wells Fargo, N.A., as administrative agent (the “Agent”), and certain purchasers. Under the RPA, Ortho FinanceCo I may sell receivables in amounts up to a $75.0 million limit, subject to certain conditions, including that, at any date of determination, the aggregate capital paid to Ortho FinanceCo I does not exceed a “capital coverage amount,” equal to an adjusted net receivables pool balance minus a required reserve. Ortho FinanceCo I has guaranteed the prompt payment of the sold receivables, and to secure the prompt payment and performance of such guaranteed obligations, Ortho FinanceCo I has granted a security interest to the Agent, for the benefit of the purchasers, in all assets of Ortho FinanceCo I. We, in our capacity as master servicer under the RPA, are responsible for administering and collecting the receivables and have made customary representations, warranties, covenants and indemnities. We have also provided a performance guarantee for the benefit of Ortho FinanceCo I to cause the due and punctual performance by us of our obligations as master servicer. The proceeds of the RPA were used, in part, to pay off the outstanding balance of the Financing Program.

We or our affiliates, including investment funds affiliated with Carlyle, at any time and from time to time, may purchase Senior Notes or our other indebtedness. Any such purchases may be made through the open market or privately negotiated transactions with third parties or pursuant to one or more tender or exchange offers or otherwise, upon such terms and at such prices, as well as with such consideration, as we, or any of our affiliates, may determine. Such purchases could result in a change to the allocation between the Issuers of the indebtedness represented by the Senior Notes and could have important tax consequences for holders of the Senior Notes.

Restructuring activities

We have previously undertaken several initiatives intended to strengthen operational performance and to support building our capabilities to enable us to win in the marketplace. These activities to improve operational performance are primarily cost reduction and productivity improvement initiatives in procurement, manufacturing, supply chain and logistics.

During the fiscal year ended January 3, 2016, we announced that we will outsource our equipment manufacturing operations in Rochester, New York and refurbishment operations in Neckargemund, Germany to a third-party contract manufacturing company. These initiatives were substantially completed during the fiscal year ended December 29, 2019, with total cumulative charges incurred of $75.4 million. We made cash payments of $6.5 million during the fiscal year ended January 3, 2021, and made cumulative cash payments of $71.1 million to date, as of January 2, 2022.

During the fiscal year ended December 30, 2018, we announced that we will transfer certain production lines among facilities in order to achieve operational and cost efficiencies. These initiatives were substantially completed during fiscal 2021. We have incurred net charges of $19.5 million cumulative to date comprised of $13.3 million in accelerated depreciation and $6.2 million in severance and other facility related costs. We have made cumulative cash payments of $15.4 million related to these initiatives, including $9.4 million cumulative to date for capital expenditures through January 2, 2022.

For additional information on our restructuring activities, see Note 12, “Restructuring costs,” to our audited consolidated financial statements incorporated by reference into this joint proxy statement/prospectus.

Outlook

Short-term liquidity outlook

We expect that our cash and cash equivalents, cash flows from operations and amounts available under the Revolving Credit Facility will be sufficient to meet debt service requirements, working capital requirements, and capital expenditures for the

216

next 12 months from the date of this joint proxy statement/prospectus. Our ability to make scheduled payments of principal or interest on, or to refinance, our indebtedness or to fund working capital requirements, capital expenditures and other current obligations will depend on our ability to generate cash from operations. Such cash generation is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

We are focused on expanding the number of instruments placed in the field and solidifying long-term contractual relationships with customers. In order to achieve this goal, in certain jurisdictions where it is permitted, we have leveraged a reagent rental model that has been recognized as more attractive to certain customers. In this model, we lease, rather than sell, instruments to our customers. Over the term of the contract, the purchase price of the instrument is embedded in the price of the assays and reagents. Going forward, we intend to increase the number of reagent rental placements in developed markets, a strategy that we believe is beneficial to our commercial goals because it lowers our customers’ upfront capital costs and therefore allows purchasing decisions to be made at the lab manager level. For these same reasons, the reagent rental model also benefits our commercial strategy in emerging markets. We believe that the shift in our sales strategy will grow our installed base, thereby increasing sales of higher-margin assays, reagents and other consumables over the life of the customer contracts and enhancing our recurring revenue and cash flows.

During the fiscal year ended January 2, 2022, we transferred $106.3 million of instrument inventories from Inventories to Property, plant and equipment, further increasing our investment in property, plant and equipment. We currently estimate that we will transfer additional instrument inventories of approximately $135 million during fiscal year 2022.

We expect to make contributions of $1.9 million to our defined benefit plans in fiscal 2022. The amount of any contributions is dependent on the future economic environment and investment returns, and we are unable to reasonably estimate pension contributions beyond fiscal 2022. See Note 14, “Long-term employee benefits” to our audited consolidated financial statements incorporated by reference into this joint proxy statement/prospectus for further discussion of our defined benefit plans.

As of January 2, 2022, we had approximately $232.4 million of purchase obligations, which includes agreements to purchase goods or services that is enforceable and legally binding, and that specifies all significant terms, including (i) fixed or minimum quantities to be purchased, (ii) fixed, minimum or variable price provisions and (iii) the approximate timing of the transaction. We expect the majority of the payments related to these purchase obligations to be made during fiscal year 2022. We entered into a consulting services agreement with an affiliate of Carlyle, which was amended on October 15, 2020. The agreement terminates upon the earlier of (i) the second anniversary of our IPO and (ii) the date that Carlyle collectively and beneficially owns, directly or indirectly, less than ten percent (10%) of our outstanding voting securities. For a description of the agreement and our obligations, see Note 20, “Related party transactions” to our audited consolidated financial statements incorporated by reference into this joint proxy statement/prospectus.

As of January 2, 2022, the total undiscounted future payments we expect to make in connection with our operating lease agreements was $30.7 million. Approximately $13.7 million of these payments are expected to be made in fiscal year 2022. See Note 10, “Leases” to our audited consolidated financial statements incorporated by reference into this joint proxy statement/prospectus.

Based on our forecasts, we believe that cash flow from operations, available cash on hand and available borrowing capacity under our Revolving Credit Facility will be sufficient to fund continuing operations for at least the next 12 months from the issuance date of this joint proxy statement/prospectus. Our debt agreements contain various covenants that may restrict our ability to borrow on available credit facilities and future financing arrangements and require us to remain below a specific credit coverage threshold. Our credit agreement has a financial covenant (ratio of Net First Lien Secured Debt to Adjusted EBITDA not to exceed 5.5-to-1, subject to a 50 basis point step-down on September 30, 2022) that is tested when borrowings and letters of credit issued under the Revolving Credit Facility exceed 30% of the committed amount at any period end reporting date. As of and January 2, 2022, we had no outstanding borrowings under our Revolving Credit Facility. Due to the current economic and business uncertainty resulting from the ongoing COVID-19 pandemic, from time to time we may borrow from our Revolving Credit Facility, if needed, during fiscal year 2022. We believe that we will continue to comply with the financial covenant for the next 12 months. In the event we do not comply with the financial covenant of the Revolving Credit Facility, the lenders will have the right to call on all of the borrowings under the Revolving Credit Facility. If the lenders on the Revolving Credit Facility terminate their commitments and accelerate the loans, this would become a cross default to other material indebtedness. We believe that we will continue to be in compliance with these covenants. However, should it become necessary, we may seek to raise additional capital within the next 12 months through borrowings on credit facilities, other financing activities and/or the private sale of equity securities.

217

Long-term liquidity outlook

UK Holdco is a holding company with no business operations or assets other than the capital stock of its direct and indirect subsidiaries and intercompany loan receivables. Consequently, UK Holdco is dependent on loans, dividends, interest and other payments from its subsidiaries to make principal and interest payments on our indebtedness, meet working capital requirements and make capital expenditures. As presently structured, its operating subsidiaries are the sole source of cash for such payments and there is no assurance that the cash for those interest payments will be available. We believe our organizational structure will allow the necessary flexibility to move funds throughout our subsidiaries to meet our operational working capital needs. In the future, the Issuers and borrowers under our Senior Secured Credit Facilities may also need to refinance all or a portion of the borrowings under the Senior Notes and the Senior Secured Credit Facilities on or prior to maturity. If refinancing is necessary, there can be no assurance that we will be able to secure such financing on acceptable terms, or at all.

We have milestone payment obligations to partners and suppliers which are contingent on regulatory approval. Future launch-related milestone payments of up to $60.0 million may be owed to Quotient for MosaiQ, however the future timing of when such payments would be made, if ever, is unclear at this time. See Note 13, “Collaborations and other relationships,” to our audited consolidated financial statements incorporated by reference into this joint proxy statement/prospectus for further discussion of the Quotient relationship.

As of January 2, 2022, we had approximately $27.9 million of uncertain tax positions, not including interest and penalties. Due to the high degree of uncertainty regarding future timing of cash flows associated with these liabilities, we are unable to estimate the years in which settlement will occur with the respective taxing authorities. These amounts have been excluded from the above table. See Note 16, “Income taxes,” to our audited consolidated financial statements incorporated by reference into this joint proxy statement/prospectus for further discussion of our tax obligations.

Our ability to make payments on and to refinance our indebtedness and to fund planned capital expenditures will depend on our ability to generate cash in the future. This is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control as well as the factors described in “Risk Factors” and “Cautionary Statement Concerning Forward-Looking Statements” of this joint proxy statement/prospectus.

Recent Accounting Pronouncements

Information regarding new accounting pronouncements is included in Note 3, “Summary of significant accounting policies,” to our audited consolidated financial statements incorporated by reference into this joint proxy statement/prospectus.

Quantitative and Qualitative Disclosures About Market Risk

Our business and financial results are affected by fluctuations in world financial markets, including interest rates and currency exchange rates. We manage these risks through normal operating and financing activities and, when deemed appropriate, through the use of derivative financial instruments. We have policies governing our use of derivative instruments, and we do not enter into financial instruments for trading or speculative purposes.

Interest rate risk

We are subject to interest rate market risk in connection with our long-term debt. Our principal interest exposure will relate to outstanding amounts under our Senior Secured Credit Facilities. Our Senior Secured Credit Facilities provide for variable rate borrowings of up to $2,325.0 million under the Dollar Term Loan Facility, €337.4 million under the Euro Term Loan Facility and $500.0 million under our Revolving Credit Facility. Assuming our Senior Secured Credit Facilities are fully drawn (and to the extent that LIBOR is in excess of the 0.00% floor rate of our Senior Secured Credit Facilities), each one-eighth percentage point increase or decrease in the applicable interest rates would correspondingly change our interest expense on our Senior Secured Credit Facilities by approximately $2.6 million per year before considering the impact of derivative instruments. For further discussion of the risks related to our Senior Secured Credit Facilities, see “Risk Factors—Risks Relating to Ortho’s Business—Risks Relating to Ortho’s Indebtedness—Ortho’s substantial indebtedness could adversely affect Ortho’s financial condition, limit Ortho’s ability to raise additional capital to fund its operations and prevent Ortho from fulfilling our obligations under its indebtedness.”

218

We selectively use derivative instruments to reduce market risk associated with changes in interest rates. The use of derivatives is intended for hedging purposes only and we do not enter into derivative instruments for speculative purposes. As of January 2, 2022, we have an interest rate cap agreement to hedge our interest rate exposures related to our variable rate borrowings under the Senior Secured Credit Facilities with an interest rate cap amount of 3.5%, with caplets that mature through December 31, 2023.

We have also entered into an interest rate swap agreement, which fixed a portion of the variable interest due on our variable rate debt. Under the terms of the agreement, we will pay a fixed rate of 1.635% and receive a variable rate of interest based on one-month LIBOR (as defined) from the counterparty which is reset every month through December 31, 2023. As of January 2, 2022, the notional amount of the interest rate swap was $1,500 million.

The notional value of these instruments is expected to be $1,000 million in fiscal 2022 and $500 million in fiscal 2023.

Foreign exchange rates risk

We are exposed to foreign currency risk by virtue of our international operations. We derived approximately 50% of our revenue for the fiscal year ended January 2, 2022 outside the U.S. For translation of operations in non-U.S. dollar currencies, the local currency of most entities is the functional currency. Our foreign assets and liabilities are translated into U.S. dollars at the exchange rates existing at the respective balance sheet dates, and income and expense items are translated at the average exchange rate for each relevant period. Foreign exchange effects from the translation of our balance sheet resulted in a comprehensive loss of $17.5 million for the fiscal year ended January 2, 2022. Foreign exchange effects from the translation of our balance sheet resulted in a comprehensive gain of $59.4 million for the fiscal year ended January 3, 2021. Foreign exchange effects from the translation of our balance sheet resulted in a comprehensive loss of $0.9 million for the fiscal year ended December 29, 2019. Adjustments resulting from the re-measurement of transactions denominated in foreign currencies other than the functional currency of our subsidiaries are expensed as incurred.

In the majority of our jurisdictions, we earn revenue and incur costs in the currency used in such jurisdiction. We incur significant costs in foreign currencies including Brazilian Real, British Pound, Chinese Yuan/Renminbi, Euro, Indian Rupee, Japanese Yen, Mexican Peso, and the Swiss Franc. As a result, movements in exchange rates cause our revenue and expenses to fluctuate, impacting our profitability and cash flows. Future business operations and opportunities, including the continued expansion of our business outside North America, may further increase the risk that cash flows resulting from these activities may be adversely affected by changes in currency exchange rates.

Like many multi-national companies, we have exposure to the British Pound. We are negatively impacted by a lower British Pound exchange rate from translation impact when compared to the U.S. dollar, but we also benefit from expenses denominated in British Pound, as well as some cross-border transactions at a lower exchange rate. The magnitude of the impact is dependent on our business volumes in the U.K., forward contract hedge positions, cross currency volume and the exchange rate.

Additionally, in order to fund the purchase price for the assets and capital stock of certain non-U.S. entities, a combination of equity contributions and intercompany loans were utilized to capitalize certain non-U.S. subsidiaries. In many instances, the intercompany loans are denominated in currencies other than the functional currency of the affected subsidiaries. Where intercompany loans are not a component of permanently invested capital of the affected subsidiaries, increases or decreases in the value of the subsidiaries’ functional currency against other currencies will affect our results of operations. During the fiscal year ended January 2, 2022, we recorded foreign currency exchange losses of $2.3 million. During the fiscal year ended January 3, 2021, we recorded net foreign currency exchange losses of $69.5 million. During the fiscal year ended December 29, 2019, we recorded net foreign currency exchange gains of $10.5 million. The foreign currency gains/losses in each period primarily consist of unrealized gains/losses related to intercompany loans denominated in currencies other than the functional currency of the affected subsidiaries. We may enter into derivative instruments to manage our foreign currency exposure on these intercompany loans in the future.

Foreign exchange risk is also managed through the use of foreign currency debt. As of January 2, 2022, €260.0 million ($296.0 million) of our senior secured Euro Term Loan Facility has been designated as, and is effective as, economic hedges of the net investment in a foreign operation. Accordingly, foreign currency transaction gains or losses due to spot rate fluctuations on the Euro-denominated debt instruments are included in foreign currency translation adjustments within accumulated other comprehensive income.

219

We have entered into foreign-currency forward contracts to manage our foreign currency exposures on foreign currency denominated firm commitments and forecasted foreign currency denominated intercompany and third-party transactions. We had forward contracts outstanding with total notional amount of $638.2 million as of January 2, 2022, with maturity dates through October 2022. Foreign-currency forward contracts that qualified and were designated for hedge accounting are recorded at their fair value as of January 2, 2022 and the unrealized gain of $1.4 million is reported as a component of other comprehensive income, all of which is expected to be reclassified to earnings in the next 12 months. Actual gains (losses) upon settlement will be recognized in earnings, within the line item impacted, during the estimated time in which the transactions are incurred. Actual losses upon settlement of $2.3 million were recognized in earnings during the fiscal year ended January 2, 2022.

Critical Accounting Estimates and Summary of Significant Accounting Policies

The preparation of our audited consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of some assets and liabilities and, in some instances, the reported amounts of revenues and expenses during the applicable reporting period. Actual results could differ from these estimates. Management believes the accounting estimates discussed below represent those accounting estimates requiring the exercise of judgment where a different set of judgments could result in the greatest changes to our reported results.

Revenue recognition

Revenue is recognized when obligations under the terms of a contract with a customer are satisfied; this occurs with the transfer of control of our goods or services. We consider revenue to be earned when all of the following criteria are met: we have a contract with a customer that creates enforceable rights and obligations; promised products or services are identified; the transaction price, or consideration we expect to receive for transferring the goods or providing services, is determinable; and we have transferred control of the promised items to the customer. A promise in a contract to transfer a distinct good or service to the customer is identified as a performance obligation. A contract’s transaction price is allocated to each performance obligation and recognized as revenue when, or as, the performance obligation is satisfied.

Product revenue includes sales of consumable supplies and test kits for equipment, sales and leases of instruments, as well as services related thereto. Revenue from sales of consumable supplies and test kits is generally recognized upon shipment or delivery based on the contractual shipping terms of the respective customer contract. Revenue from instrument sales is generally recognized upon installation and customer acceptance. Service revenue on equipment and instrument maintenance contracts is recognized over the life of the service arrangement or as services are performed.

A portion of our revenue relates to equipment lease transactions with our customers. We evaluate these leases to determine proper classification, which involves specific determinations and judgment. Revenue earned from operating leases is generally recognized on a straight-line basis over the lease term, which is normally five to seven years. Revenue earned from sales-type leases is recognized at the beginning of the lease, as well as a lease receivable and unearned interest associated with the lease.

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. We may also enter into transactions that involve multiple performance obligations, such as the sale of products and related services. In accounting for these transactions, we allocate the consideration to the deliverables by use of the relative standalone selling price method.

A portion of our product revenue includes revenue earned under reagent rental programs which provide customers the right to use instruments at no separate cost to the customer in consideration for a multi-year agreement to purchase reagents, assays and consumables. We allocate a portion of the revenue from the future consumable sale to the instrument based on the customers’ minimum volume commitment and recognize revenue at the time of the future sale of reagents, assays and consumables. The cost of the instrument is capitalized within property and equipment, and is charged to cost of product revenue on a straight-line basis over the term of the minimum purchase agreement. Revenue earned from operating leases is recognized over the lease term, which is normally five to seven years. Revenue earned under sales-type leases is recognized at the beginning of the lease, as well as a lease receivable and unearned interest associated with the lease. Revenue is recognized when control has transferred for the reagents, assays and consumables. Costs related to product sales are recognized at time of delivery.

220

We recognize product revenues at the net sales price, which includes estimates of variable consideration related to rebates and volume discounts. Rights of return are generally not included in our arrangements with customers. Our estimates of rebates and discounts are determined using the expected value method and take into consideration historical experience, contractual and statutory requirements, and other relevant information such as forecasted activity. These reserves reflect our best estimate of the amount of consideration to which it is entitled. The amount of variable consideration included in the net sales price is limited to the amount that is probable not to result in a significant future reversal of cumulative revenue under the contract.

We enter into collaboration arrangements that generate collaboration revenue and royalty revenue from license agreements. Revenue from collaborations is presented “gross” where we are deemed the principal in the arrangement and “net” where we are deemed the agent in the arrangement.

Inventories

Inventories are stated at the lower of cost and net realizable value on a first-in, first-out method. Elements of cost include raw materials, direct labor and manufacturing overhead.

We periodically review inventory for both potential obsolescence and potential declines in anticipated selling prices. In this review, we make assumptions about the future demand for and market value of the inventory and based upon these assumptions estimate the amount of any obsolete, unmarketable, slow moving or overvalued inventory. We write down the value of our inventories by an amount equal to the difference between the cost of the inventory and the net realizable value. Historically, such write-downs have not been significant. If actual market conditions are less favorable than those projected by management at the time of the assessment, however, additional inventory write-downs may be required, which could reduce our gross profit and earnings.

Customer leased instruments

Determining the economic life of our leased instruments requires significant accounting estimates and judgment. These estimates are based on our historical experience and existing contractual terms. Our estimate of the economic life of our instruments is ten years. We depreciate these assets over the lesser of the useful economic life and the length of the contract, which typically ranges between five and eight years. We believe these lives represent the periods during which the instruments are expected to be usable, with normal repairs and maintenance, for the purposes for which they are intended. We regularly evaluate the economic life of existing and new products for purposes of this determination.

Goodwill

Goodwill represents costs in excess of fair values assigned to underlying net assets of acquired companies. We evaluate goodwill for impairment on an annual basis in our fiscal fourth quarter, unless conditions exist that would require a more frequent evaluation.

When testing goodwill for impairment, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (more than 50%) that the fair value of a reporting unit is less than its carrying amount. Such qualitative factors may include the following: macroeconomic conditions; industry and market considerations; cost factors; overall financial performance; and other relevant entity-specific events.

If we elect to perform a qualitative assessment and determine that an impairment is more likely than not, we will perform a quantitative impairment test, otherwise no further analysis is required. We may also elect not to perform the qualitative assessment and, instead, proceed directly to performing the quantitative impairment test, under which the evaluation of impairment involves comparing the current fair value of each reporting unit to its carrying value, including goodwill. The ultimate outcome of the goodwill impairment assessment for a reporting unit should be the same whether we choose to perform the qualitative assessment or proceed directly to the quantitative impairment test.

If the carrying amount of a reporting unit, including goodwill, exceeds the estimated fair value, then we would record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (limited to the amount of goodwill).

221

We estimate the fair value of our reporting units by using forecasts of discounted future cash flows and peer market multiples. The inputs utilized in these analyses are classified as Level 3 inputs within the fair value hierarchy as defined in ASC 820, Fair Value Measurement.

The process of evaluating the potential impairment of goodwill is subjective because it requires the use of estimates and assumptions as to our future cash flows, which includes assumed revenue growth rates, long term growth rates and discount rates. Although we base cash flow forecasts on significant assumptions, including assumed revenue growth rates, long term growth rates and discount rates, that are consistent with plans and estimates we use to manage our Company, there is significant judgment in determining the cash flows. We also consider revenue and earnings trading multiples of the peer companies that have similar financial characteristics to the reporting units. Due to the inherent uncertainty in forecasting cash flows and earnings, actual future results may vary significantly from the forecasts. Based on the degree of uncertainty, we cannot quantify the potential effect of the change in estimate on our results of operations and financial position.

Impairment of long-lived assets

The process of evaluating the potential impairment of other long-lived assets, such as our property, plant and equipment and definite-lived intangible assets, such as technology, tradenames and customer relationships, is subjective and requires judgment. We review long-lived assets for impairment when events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. This impairment test may be triggered by a decrease in the market price of a long-lived asset, an adverse change in the extent or manner in which the asset is being used, or a forecast of continuing losses associated with the use of the asset. If the fair value is less than the asset’s carrying amount, we recognize a loss for the difference. The fair value methodology used is an estimate of fair market value and is based on the discounted future cash flows of the asset or quoted market prices of similar assets. Based on these assumptions and estimates, we determine whether we need an impairment charge to reduce the value of the asset stated on our balance sheet to reflect its estimated fair value.

Income taxes

The provision for income taxes was determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the period. Deferred taxes result from differences between the financial and tax basis of our assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Deferred tax assets are also recognized for operating losses and tax credit carryforwards. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Deferred tax assets and liabilities are measured using enacted tax rates applicable in the years in which they are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax law is recognized in income in the period that includes the enactment date.

We do not intend to permanently reinvest earnings of foreign subsidiaries at this time. As such, we provide for income taxes and foreign withholding taxes, where applicable, on undistributed earnings. Any repatriation of undistributed earnings would be done at little or no tax cost.

The breadth of our operations and the global complexity of tax regulations require assessments of uncertainties and judgments in estimating taxes we will ultimately pay. The final taxes paid are dependent upon many factors, including negotiations with taxing authorities in various jurisdictions, outcomes of tax litigation and resolution of disputes arising from federal, state and international tax audits in the normal course of business. A liability for uncertain tax positions is recorded when management concludes that the likelihood of sustaining such positions upon examination by taxing authorities is less than “more likely than not.” Interest and penalties accrued related to unrecognized tax benefits are included in the provision for taxes on income.

Stock-based compensation

Stock-based compensation, comprised of UK Holdco stock options and restricted shares, is measured at fair value on the grant date or date of modification, as applicable. Determining the amount of stock-based compensation expense to be recorded requires us to develop estimates to be used in calculating the grant-date fair value of stock options. Our valuation model requires us to make estimates of the following assumptions:

222

Fair value of our ordinary shares—Prior to Ortho’s initial public offering in January 2021, the valuation of our ordinary shares was determined in accordance with the guidelines outlined in the American Institute of Certified Public Accountants, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. We considered numerous objective and subjective factors to determine our best estimate of the fair value of our ordinary shares, including but not limited to, the following factors:

| • |  | the fact that we were a private company with illiquid securities;

| • |  | historical operating results;

| • |  | discounted future cash flows, based on projected operating results;

| • |  | financial information of comparable public companies; and

| • |  | the risk involved in the investment, as related to earnings stability, capital structure, competition and market potential.

Expected volatility—We are responsible for estimating volatility and have considered a number of factors, including third-party estimates and comparable companies, when estimating volatility.

Expected term—We estimate the remaining expected life of options as the mid-point between the expected time to vest and the maturity of the options.

Risk-free interest rate—The yield interpolated from U.S. Constant Maturity Treasury rates for a period commensurate with the expected term assumption is used as the risk-free interest rate.

THE COMBINATIONS

This section of the joint proxy statement/prospectus describes material aspects of the Combinations. The description in this section and elsewhere in this joint proxy statement/prospectus is qualified in its entirety by reference to the complete text of the BCA, a copy of which is attached to this joint proxy statement/prospectus as Annex A and is incorporated by reference into this joint proxy statement/prospectus. This summary may not contain all of the information that is important to you. You should carefully read this entire document, including the full text of the BCA and the other documents referred to in this document, for a more complete understanding of the Combinations. This section is not intended to provide you with any factual information about Ortho or Quidel. Such information can be found elsewhere in this joint proxy statement/prospectus and in the public filings Quidel and Ortho make with the SEC, as described in the section entitled “Where You Can Find More Information” of this joint proxy statement/prospectus.

The Combinations

As discussed throughout this joint proxy statement/prospectus, Ortho is asking its shareholders to approve the Ortho Scheme and Quidel is asking its stockholders to adopt the BCA, pursuant to which Ortho and Quidel will enter into a business combination and operate under Topco, a new holding company incorporated in Delaware. The Combinations will be implemented in two main steps, which are the Ortho Scheme and the Quidel Merger.

In the Ortho Scheme:

| • |  | each Ortho Share will be acquired by a nominee of Topco (or, if such nominee holds the Ortho Shares today, transferred within the nominee), such that Ortho will become a wholly owned subsidiary of Topco; and

| • |  | at the effective time of the Ortho Scheme, each Ortho Share, other than Ortho Shares held by Ortho in treasury (if any), will be acquired by a nominee (or, if such nominee holds the Ortho Shares today, transferred within the nominee) on behalf and for the benefit of Topco in exchange for 0.1055 Topco Shares and $7.14 in cash.

In the Quidel Merger:

| • |  | U.S. Merger Sub will merge with and into Quidel immediately following consummation of the Ortho Scheme, with Quidel surviving the merger as a wholly owned subsidiary of Topco; and

| • |  | at the effective time of the Quidel Merger, each Quidel Share, other than Quidel Shares held by Quidel, Ortho or U.S. Merger Sub, will be converted into the right to receive one Topco Share.

As a result of the Combinations, Ortho and Quidel will each become wholly owned subsidiaries of Topco, and Ortho shareholders and Quidel stockholders will become Topco stockholders. Based on the respective capitalizations of Ortho and Quidel as of the date the parties entered into the BCA, immediately following consummation of the Combinations, it is expected that former Ortho shareholders will receive approximately $1.7 billion in cash in the aggregate (based on the number of Ortho Shares outstanding as of December 31, 2021) and will own approximately 38% of Topco and former Quidel stockholders will own approximately 62% of Topco, on a fully diluted basis, based on the respective capitalizations of Ortho and Quidel as of the date the parties entered into the BCA.

Based on the number of Ortho Shares and Quidel Shares outstanding as of December 31, 2021, Topco is expected to issue approximately 25,018,161 Topco Shares to the Ortho shareholders upon completion of the Ortho Scheme and approximately 41,686,165 Topco Shares to the Quidel stockholders upon completion of the Quidel Merger.

The parties intend to list the Topco Shares to be issued in the Combinations on Nasdaq.

Background of the Combinations

In the ordinary course of their respective businesses, senior management and the boards of directors of each of Quidel and Ortho regularly review, assess and discuss developments in their markets, their company’s performance, strategy and competitive position and potential strategic initiatives and alternatives in light of economic and market conditions. From time

to time Quidel and Ortho have also reviewed and discussed with other parties potential business combinations, joint ventures, strategic alliances and other strategic transactions that might advance their strategic objectives and enhance stockholder

224

value. As part of these ongoing reviews and discussions with respect to the Combinations, Quidel and Ortho have each considered, among other things, the significant opportunity presented by the Combinations to enhance their respective offerings in a rapidly evolving industry and the current strategic environment.

Prior to and following completion of its initial public offering, continuing into 2021, Ortho engaged in discussions with a number of potential strategic parties regarding potential strategic transactions, among other things, acquisition transactions consistent with Ortho’s growth strategy, strategic alliances and potential business combinations. From time to time during this period, Ortho engaged in discussions with a strategic party referred to as Party A with respect to a potential business combination transaction. Although Ortho and Party A discussed terms for a potential business combination transaction at a high level, Ortho and Party A mutually agreed in spring 2021 not to proceed further with negotiations.

During early 2021, consistent with Quidel’s growth strategy, Quidel engaged in discussions with several potential strategic parties regarding potential strategic transactions or acquisitions, including to assess strategic fit, financial fit and ability to execute. The Quidel board of directors determined that each such potential transaction was not a strategic fit at that time.

As part of Ortho’s ongoing consideration of strategic transaction opportunities, on May 18, 2021, Ortho held an M&A strategy session in Denver, Colorado with members of Ortho’s senior management, representatives of Carlyle (attending virtually) and representatives of Goldman Sachs & Co. LLC (“Goldman Sachs”), at which a range of potential strategic transaction opportunities were discussed, including potential transformative business combination transactions with three parties. At the conclusion of the meeting, Ortho senior management asked Goldman Sachs to initiate outreach to certain potential strategic partners, including Quidel, a strategic party referred to as “Party B” and a strategic party referred to as “Party C,” with respect to potential strategic transactions.

Following the meeting, as requested by Ortho senior management, a representative of Goldman Sachs contacted Doug Bryant, Quidel’s President and Chief Executive Officer, to seek approval to provide Mr. Bryant’s contact information to Christopher Smith, Ortho’s Chairman and Chief Executive Officer. On May 20, 2021, Mr. Bryant and Mr. Smith were introduced by email.

In addition, following the May 18 strategy session, representatives of Goldman Sachs contacted Party B and Party C to explore the possibility of strategic discussions with Ortho. Mr. Smith exchanged messages with the chief executive officer of Party B, but these messages did not result in any transaction proposals or substantive discussions. Party C indicated to representatives of Goldman Sachs that it would consider a transaction at an attractive valuation, but after further analysis, Ortho senior management concluded that a transaction with Party C was not an optimal strategic fit with Ortho, and that the transaction would result in limited growth opportunities.

On May 25, 2021, Mr. Bryant and Mr. Smith met telephonically to discuss potential transactions between Quidel and Ortho, including collaboration and partnership opportunities. In particular, Mr. Bryant and Mr. Smith discussed Quidel’s Sofia and Savanna platforms and how such platforms could complement Ortho’s larger-scale instrumentation for clinical chemistry and high-throughput immunoassay platforms. Mr. Bryant and Mr. Smith also discussed Ortho’s interests in expanding its product offerings into molecular testing products and leveraging Ortho’s global footprint and international sales force, along with the complementary nature of Quidel’s and Ortho’s customer bases and potential opportunities for the two companies to collaborate. In addition, Mr. Bryant and Mr. Smith discussed Quidel’s potential interest in exploring how their company might benefit from Ortho’s larger global commercial footprint for the launch of Quidel’s Savanna instrument. A potential combination of Quidel and Ortho was briefly discussed; however, Mr. Bryant and Mr. Smith agreed at that point to focus solely on jointly exploring various collaboration structures and to assess how working together might benefit both companies. Following the meeting, Mr. Bryant and Mr. Smith each agreed that they would convene a small group of executives to further explore collaboration opportunities and review publicly available investor relations materials about the other company.

On June 8, 2021, members of Quidel’s and Ortho’s senior management met at Ortho’s temporary office facility in Denver, Colorado to learn about the other company’s business at a high level and discuss potential collaboration frameworks. As a result of the discussions at the meeting, the parties identified complementary aspects of the businesses and determined that a collaboration had the potential to benefit both companies by fostering the ability through greater scale and scope to compete with larger diagnostic companies. Specifically, for Quidel, a collaboration would provide access to a larger global commercial footprint, and for Ortho, a collaboration would provide access to higher-growth IVD segments, including molecular and point-of care testing platforms. Quidel and Ortho also discussed potential opportunities for joint or

225

complementary technology development to advance both companies’ R&D pipelines. The parties also decided to put in place a Confidentiality Agreement to initiate the exploration of potential collaboration frameworks.

On June 12, 2021, Quidel sent Ortho a draft Confidentiality Agreement, that included updates to an expired agreement entered into between the parties in August 2018. On June 18, 2021, Quidel and Ortho entered into a Confidentiality Agreement, covering the sharing of confidential information. The Confidentiality Agreement did not include a stand-still provision.

On June 25, 2021, at a business update meeting of the Quidel board of directors, members of Quidel’s senior management provided a summary of potential collaborations and other business development opportunities for Quidel, including potential collaboration opportunities with Ortho, as well as the potential acquisition of another target company. The Quidel board of directors and members of Quidel’s management reviewed preliminary information regarding factors relating to a potential acquisition of such target company prepared by representatives of Perella Weinberg, who Quidel management and the Quidel board of directors regularly consulted in the ordinary course of business regarding potential merger and acquisition transactions. The Quidel board of directors approved an outreach to such target company at the board meeting, but that outreach did not progress beyond an initial contact.

On July 8, 2021, Mr. Bryant and Mr. Smith met in Orange County, California to discuss each company’s goals for a potential collaboration. Mr. Bryant noted a collaboration could be a good strategic fit for Quidel, and could provide Quidel with an opportunity to expand its geographic reach and to compete more effectively with larger diagnostic players, especially in supporting the launch of Quidel’s Savanna platform. Mr. Smith agreed and noted that a collaboration could assist Ortho in expanding its product offerings, but emphasized that the collaboration would need to result in long-term sustainable growth for both companies.

Also on July 8, 2021, members of Quidel senior management discussed with representatives of Perella Weinberg preliminary financial information regarding a potential combination transaction with Ortho, assuming all-stock, all-cash or 50 percent stock/50 percent cash consideration. Quidel management had requested such information to assist them in developing preliminary thoughts on potential financial implications if the discussions with Ortho moved beyond a potential collaboration to a potential combination.

On July 19, 2021, Mr. Smith met with representatives of J.P. Morgan at their offices in New York, New York to discuss the strategic rationale for opportunities to collaborate with Quidel and engagement of J.P. Morgan for financial advice on such opportunities. A follow-up discussion on such matters occurred on July 23, 2021.

On July 20, 2021, members of Quidel’s and Ortho’s senior management met at Quidel’s offices in San Diego, California to continue discussions regarding potential collaboration and partnership opportunities between the two companies. During the meetings, members of management of each of Ortho and Quidel provided overviews of their respective businesses and discussed potential opportunities to collaborate.

On July 23, 2021, Mr. Bryant and Mr. Smith met telephonically to discuss the July 20 meeting and agreed that each company’s respective teams would continue working to assess whether and how the parties might collaborate. Mr. Bryant told Mr. Smith that he would provide the Quidel board of directors at the board meeting later that day with a brief update on the potential opportunities being discussed with Ortho. Mr. Bryant also told Mr. Smith that Mr. Bryant intended to provide the Quidel board of directors with a more detailed assessment of the potential opportunities identified by the companies at the regularly scheduled quarterly board meeting on August 30, 2021. During that same discussion, Mr. Smith informed Mr. Bryant that Ortho had begun working with J.P. Morgan to provide financial advice regarding the opportunities being discussed with Quidel. Mr. Bryant and Mr. Smith agreed to meet in person in New York in early September.

Later on July 23, 2021, at a business update meeting of the Quidel board of directors, members of Quidel’s senior management provided an update on the potential collaboration opportunity with Ortho, and the Quidel board of directors and management discussed potential financial advisors who might be able to advise the board and management with respect to the potential opportunities, including Perella Weinberg.

On August 5, 2021, as a follow-up to the July 20 meeting, Ed Russell, Quidel’s Senior Vice President, Business Development, Rhys de Callier, Quidel’s Vice President, Strategy and Portfolio Management, Michael S. Iskra, Ortho’s Executive Vice President of Commercial Excellence and Strategy, and Thomas Robinson, Ortho’s Vice President, Strategy and Corporate Development, met telephonically to discuss preliminary collaboration ideas and frameworks.

226

On August 6, 2021, at a business update meeting of the Quidel board of directors, Quidel’s senior management provided an update on the review of the potential collaboration opportunity with Ortho, among other topics.

On August 11, 2021, Mr. Bryant and Mr. Smith met telephonically to discuss the status of each company’s review of the potential collaboration opportunities.

On August 13, 2021, at a meeting of the Ortho board of directors to discuss various matters, Mr. Smith provided a summary of potential business development opportunities for Ortho, including potential collaboration opportunities with Quidel.

On August 13, 2021, Ortho’s senior management and representatives of J.P. Morgan met telephonically to discuss the meeting of the Ortho board of directors earlier that day and certain financial information regarding Quidel.

On August 18, 2021, Ortho provided Quidel with a proposal of potential collaboration opportunities that Ortho had identified, including: (1) in the United States, some form of commercial collaboration between the companies for the launch of Quidel’s Savanna platform, with the potential to expand to other Quidel products, (2) outside of the United States, Ortho could become a distributor for Quidel legacy products for select countries where Ortho had an existing direct commercial model, with the addition of Quidel’s Savanna platform when production capacity allowed, (3) a research and development collaboration to develop a ‘Sofia-like’ small benchtop point-of-care analyzer for clinical chemistry, using Ortho’s dry chemistry technology, and (4) certain potential collaborations relating to manufacturing and operations. This proposed collaboration framework did not contemplate a business combination between Ortho and Quidel.

On August 20, 2021, Ortho’s senior management and representatives of J.P. Morgan met telephonically for an initial discussion of exploring a potential merger of equals transaction with Quidel in parallel with the ongoing discussions of collaboration opportunities with Quidel, in light of the potential complexities of, and potentially lower synergies associated with, a strategic partnership.

On August 23, 2021, Robert Bujarski, Quidel’s Chief Operating Officer, Mr. Russell, Mr. Iskra, and Mr. Robinson met telephonically to discuss Ortho’s collaboration proposal. Following the August 23, 2021 meeting with Quidel, representatives of Ortho directed J.P. Morgan to focus more fully on the potential merger of equals in light of the potential complexities of a strategic partnership, Ortho’s initial perceptions of which were confirmed at the August 23, 2021 meeting.

On August 26, 2021, at the direction of management of Quidel and Ortho, respectively, representatives of Perella Weinberg and J.P. Morgan held an initial telephonic meeting to discuss a potential business combination between Quidel and Ortho and considerations regarding the process for exploring a potential transaction.

On August 30, 2021, at a regularly scheduled quarterly meeting of the Quidel board of directors, which was attended in part by certain members of Quidel’s senior management, among other matters, Mr. Russell provided an update on the collaboration discussions between Quidel and Ortho. At the request of the Quidel board of directors, senior management also discussed certain preliminary financial information relating to a potential combination of Quidel and Ortho prepared by Perella Weinberg that was based on information provided by Quidel senior management and publicly available information.

On September 1, 2021, J.P. Morgan delivered a presentation to Ortho’s senior management and representatives of Carlyle regarding its preliminary analysis of the potential combination of Ortho and Quidel. Throughout fall 2021, representatives of Carlyle were involved in Ortho’s evaluation of the potential combination both through participation from members of the Ortho board of directors appointed by Carlyle and evaluation of the transaction from Carlyle’s perspective as a significant shareholder that would continue to hold a meaningful interest in the combined company.

On September 7, 2021, Mr. Bryant and Mr. Smith met in person in New York, New York, and discussed the potential benefits of a collaboration between the companies and considerations related to a potential combination of the companies as a merger of equals, including potential governance structures.

On September 8, 2021, Mr. Smith let Mr. Bryant know that Ortho announced and commenced a secondary offering on September 7, 2021. Mr. Smith also suggested they schedule a meeting in San Diego, California later that month.

On September 13, 2021, at the direction of Quidel’s and Ortho’s management, representatives from Perella Weinberg and J.P. Morgan met telephonically to discuss a possible business combination. Representatives from J.P. Morgan discussed the potential for a merger transaction between Quidel and Ortho. As proposed by Ortho, the combined company would have a chief executive officer from one company and a chairman from the other and the board of directors would be split based on relative ownership. Later in the call, representatives from Perella Weinberg and J.P. Morgan discussed whether the parties would exchange long-range plans.

227

Also on September 13, 2021, representatives of J.P. Morgan sent to Ortho an initial draft of a non-binding summary of proposed terms. On September 16, 2021, representatives of J.P. Morgan shared with representatives of Carlyle a draft non-binding summary of proposed terms, draft exclusivity agreement and illustrative work plan for the proposed combination with Quidel, reflecting input from Ortho senior management, certain representatives of Carlyle, Latham & Watkins LLP (“Latham”), Ortho’s outside counsel, and J.P. Morgan.

On September 21, 2021 Mr. Bryant, Randy Steward, Quidel’s Chief Financial Officer, Mr. Bujarski, Michelle Hodges, Quidel’s Senior Vice President, General Counsel, Mr. Smith, Joseph Busky, Ortho’s Chief Financial Officer, Mr. Robinson and Mr. Iskra met at Quidel’s offices in San Diego, California to discuss matters related to a proposed merger of equals, including the drivers for a combination, the potential exchange of each of Quidel’s and Ortho’s long-range plans, research and development opportunities, structuring of a combined company, and next steps, including undertaking an analysis of potential synergies from a combination and directing financial advisors for each company to prepare preliminary financial information relating to each of the companies and the proposed transaction.

On September 22, 2021, Mr. Smith suggested to Mr. Bryant that Mr. Steward and Mr. Busky share the long-range plans discussed at the prior day’s meeting. Mr. Smith also told Mr. Bryant that he would put Mr. Bryant in contact with representatives of Carlyle so that they could separately schedule a meeting, which he did on September 23, 2021.

On September 22, 2021, at the direction of Quidel management, representatives of Perella Weinberg delivered a copy of the Quidel long-range plan to J.P. Morgan, who then shared the Quidel long-range plan with members of Ortho’s senior management. See the section entitled “Ortho Unaudited Forward-Looking Financial Information—Ortho Management Projections for Quidel.”

On September 23, 2021, members of Ortho’s senior management met telephonically with representatives of J.P. Morgan and Latham to discuss high-level terms for a potential transaction with Quidel, including relating to structure and timing of sharing Ortho’s long-range plan. Members of Ortho’s senior management and representatives of Carlyle, J.P. Morgan and Latham met telephonically on September 24, 2021 to further discuss high-level transaction terms, including with respect to the relative ownership of the combined company, and agreed that Mr. Steward and Mr. Busky should work together to analyze potential synergies.

On September 27, 2021, Mr. Robinson sent Mr. Bryant, Mr. Steward and Mr. Bujarski high-level summaries of performance data for Ortho’s microslides and microwells for the proposed collaboration between Quidel and Ortho. Mr. Robinson also sent a request for information to prepare a mutual synergies document, which he suggested both parties use to prepare data ahead of a contemplated synergies workshop. Mr. Robinson also indicated that Mr. Smith planned to meet with the Ortho board of directors the next day to discuss next steps for a potential combination transaction.

On September 28, 2021, at a meeting of the Ortho board of directors that was attended by certain members of Ortho’s senior management and representatives of J.P. Morgan and Latham, Mr. Smith provided an overview of recent communications with Quidel and Mr. Robinson provided a summary of the strategic rationale for a combination. Representatives of J.P. Morgan provided a preliminary overview of certain financial information with respect to Quidel and Ortho. The members of the Ortho board of directors and representatives of J.P. Morgan discussed, among other things, the strategic rationale for a potential combination and next steps for pursuing a potential combination. The Ortho board of directors directed Ortho’s senior management and J.P. Morgan to advise Quidel, including through Perella Weinberg, that Ortho was willing to move forward to enter into an exclusivity agreement for a period of up to 60 days, subject to extension, based on a mutually acceptable non-binding summary of proposed terms. The Ortho board of directors authorized Ortho’s senior management and J.P. Morgan to provide to Quidel a non-binding summary of proposed terms and Ortho’s long-range plan.

On September 29, 2021, upon the request of Mr. Smith, Mr. Robinson sent Mr. Bryant a non-binding summary of proposed terms for a business combination, which would be structured as an all-stock merger of equals at a to-be-determined exchange ratio. The proposed terms provided for a 12-member board of directors with balanced representation, inclusive of board seats for Mr. Smith and Mr. Bryant, a headquarters of the combined company in San Diego and for further discussion regarding management and other key terms. The proposed terms also included a mutual exclusivity agreement, which was never signed by either party. In this communication, Mr. Robinson noted that representatives of J.P. Morgan would discuss the proposed terms with representatives of Perella Weinberg. Proposed next steps included further due diligence and workshops to analyze synergies and potential stockholder value opportunities.

228

Also on September 29, 2021, at the direction of the Ortho board of directors, senior management of Ortho provided representatives of Perella Weinberg with a copy of Ortho’s long range plan. See the section entitled “Ortho Unaudited Forward-Looking Financial Information—Ortho Management Projections for Ortho.”

On October 3, 2021, Mr. Bryant and Mr. Smith met telephonically to discuss the request for an exclusivity period and the potential benefits of a combination of Ortho and Quidel.

On October 8, 2021, at a meeting of the Quidel board of directors that was attended by certain members of Quidel’s senior management and representatives of Perella Weinberg, Mr. Bryant provided an overview of recent communications with Ortho’s senior management, including the summary of proposed terms received from Ortho. At the meeting, senior management of Quidel reviewed the strategic rationale for Quidel to enter into a potential merger-of-equals transaction, including, among other things, that the business combination would create a leading diagnostics player with a global presence, would create the potential for further advancement in telehealth technology and digital health, would increase Quidel’s global commercial footprint and infrastructure and would present an opportunity to realize significant cost and cross-selling revenue synergies.

On December 17, 2021, Gibson Dunn sent Latham a further revised non-binding summary of proposed terms; the only change was to delete the one-time right of Carlyle to designate a third board designee, at the closing of the Combinations.

On December 17, 2021, at a meeting of the Quidel board of directors that was attended by certain members of Quidel’s senior management and representatives from Perella Weinberg, representatives from Perella Weinberg discussed with the Quidel board of directors preliminary information relating to the proposed transaction, including an update on proposed premiums for the transaction and exchange ratio considerations. Members of Quidel’s senior management and the Quidel board of directors discussed the current price of Quidel common stock and the volatility observed in the stock prices of each of Quidel and Ortho. At the same meeting, Ms. Hodges provided a summary of the terms of the BCA and an overview of the transaction structure and the proposed board of directors and governance structure for the combined company. The Quidel board of directors discussed potential resolution of the open deal points and authorized Mr. Bryant to continue to negotiate these open deal points, and confirmed that the board remained fully supportive of the transaction and would continue discussion and consideration of any changes arising from such negotiations at their meeting scheduled for December 20, 2021.

On December 17, 2021, Mr. Bryant and Mr. Smith communicated before and after the meeting of the Quidel board of directors regarding the remaining open terms.

On December 19, 2021, Mr. Bryant and Mr. Smith met telephonically to discuss the status of the BCA draft and action items with respect to the proposed merger-of-equals transaction. Mr. Smith also inquired about Quidel’s business and the current

236

events in South Africa relating to the Omicron variant of the coronavirus. They also discussed Quidel’s planned strategy and messaging points for obtaining approval of the transaction by its stockholders.

On December 19, 2021, Gibson Dunn sent Latham a draft of the deed of irrevocable undertaking (“Irrevocable Undertaking”), pursuant to which Carlyle would agree to vote or procure votes in favor of the Ortho Scheme at the Ortho Court Meeting and the resolutions to be proposed at the Ortho General Meeting the shares beneficially owned by Carlyle, as described in the section entitled “Stockholders Agreement / Deed of Irrevocable Undertaking” of this joint proxy statement/prospectus. On December 19, 2021, Gibson Dunn also sent Latham revised drafts of the BCA and the Stockholders Agreement, which Ortho’s senior management discussed with representatives of Carlyle and Latham on the afternoon of December 19, 2021.

At the request of Quidel’s management due to ongoing concerns establishing an appropriate exchange ratio for the proposed merger-of-equals transaction, particularly in light of the recent volatility of Quidel’s stock price, in part due to the surging Omicron variant of the coronavirus, and the relative stability of Ortho’s stock price, Citi provided Quidel with its analyses of the financial impact of a transaction utilizing cash and stock consideration, and related governance terms of precedent cash and stock transactions.

On December 19, 2021, Mr. Bryant and Mr. Smith met telephonically and Mr. Bryant notified Mr. Smith that Quidel would be sending a further revised proposal and outlined the challenges he would face in obtaining the approval of Quidel stockholders for the transaction at the previously proposed relative stock ownership of 47% for the Ortho shareholders and 53% for the Quidel stockholders, and that in light of the increase in Quidel’s stock price, this now represented an implied 40% premium for Ortho shareholders.

On the morning of December 20, 2021, Mr. Smith updated Mr. Bryant regarding the status of a revised proposal and testing data from South Africa and reiterated Ortho’s excitement about the opportunity to combine Quidel and Ortho.

Shortly thereafter, Mr. Bryant sent Mr. Smith a further revised non-binding summary of proposed terms (the “December 20 Proposal”) that reflected significant adjustments to the structure of the transaction. The December 20 Proposal provided for a transaction in which Ortho shareholders and Quidel stockholders would own approximately 34% and 66% of the combined company on a pro forma basis, respectively. Under the revised proposal, Ortho shareholders would receive implied total consideration of $22 per share, consisting of $6.13 in cash and 0.0895 Topco Shares per Ortho Share (representing a total of $1.5 billion in cash consideration). This reflected an implied 16.6% premium to Ortho shareholders based on then current stock prices. Under this summary of proposed terms, Mr. Bryant would serve as the chief executive officer of the combined company, a Quidel director would serve as chairman of the board of directors of the combined company, a Quidel officer would serve as president of the combined company and the management team of the combined company would include Mr. Busky as chief financial officer, Mr. Iskra as chief commercial officer and Mr. Bujarski as chief operating officer, with the remaining officers selected by the designated management team (with the final determination to be made by Mr. Bryant). The board of directors of the combined company would have 10 members, with three directors from Ortho and seven directors from Quidel, inclusive of the board seats for Mr. Smith and Mr. Bryant, and Quidel would have the right to designate all committee chairs. The deal protection terms were unchanged, as were Carlyle’s rights.

Ortho’s senior management participated in multiple teleconferences with representatives of J.P. Morgan and Carlyle to discuss the December 20 Proposal.

Shortly after delivery of the December 20 Proposal, Mr. Bryant inquired of Mr. Smith how the revised proposal was received by Ortho. Mr. Smith responded that Ortho had not received the proposal well, particularly given the volatility of Quidel’s stock price, and Ortho would formally respond after the next day’s meeting of the Ortho board of directors. Mr. Smith added that, at a high level, a business combination with governance terms comparable to an acquisition could be acceptable to Ortho, but the December 20 Proposal was inadequate and the Ortho shareholders needed to receive an appropriate premium for such a transaction. Representatives of J.P. Morgan also informed representatives of Citi that the December 20 Proposal was not acceptable and would need to be improved.

Later on December 20, 2021, at a meeting of the Quidel board of directors that was attended by certain members of Quidel’s senior management and representatives from Perella Weinberg, Mr. Bryant discussed with the Quidel board of directors the revised proposed transaction terms, including the addition of a cash component to the consideration. Mr. Bryant also described to the Quidel board of directors the feedback that he had received on Ortho’s reaction to the December 20

237

Proposal. Representatives from Perella Weinberg then discussed certain updated market information and certain preliminary financial information regarding the December 20 Proposal, taking into account recent increases in Quidel’s share price relative to Ortho’s share price. Following discussion of the financial information presented by Perella Weinberg and other information presented, the Quidel board of directors authorized Mr. Bryant and the financial advisors to continue to negotiate the transaction terms (subject to the final approval of the Quidel board of directors), including authority to increase the proposed consideration, and confirmed that the board remained fully supportive of the transaction and would continue discussion and consideration of any changes arising from such negotiations.

On December 21, 2021, Mr. Bryant communicated with Mr. Smith regarding the performance of the Quickvue and Sofia tests in detecting the Omicron variant of COVID-19 and noted that he expected an announcement from the FDA shortly with respect to the ability of such tests to detect the Omicron variant of the coronavirus. On December 21, 2021, Mr. Bryant and Mr. Smith also communicated regarding the timing of a response from Ortho to the December 20 Proposal.

On December 21, 2021, Ortho’s senior management participated in a series of teleconferences with representatives of Carlyle, J.P. Morgan and Latham to discuss a response to the proposal made by Quidel on December 20, 2021 in preparation for the meeting of the Ortho board of directors that afternoon.

On December 21, 2021, at the direction of the Quidel board of directors, representatives from Perella Weinberg and Citi spoke with representatives of J.P. Morgan by telephone to convey Quidel’s revised proposal, which provided that Ortho shareholders would receive $7.14 in cash and 0.0895 Topco Shares per Ortho Share (representing a total of $1.75 billion in cash) (the “Initial December 21 Proposal”). Such consideration would, based on Quidel’s closing stock price on December 21, 2021, represent total implied value of $24 per share, which would represent a 23% premium to Ortho’s current stock price, and result in Ortho shareholders owning approximately 37% of the combined company. Also on December 21, 2021, Mr. Bryant called Mr. Smith and delivered Quidel’s revised proposal. Representatives from Carlyle also participated in teleconferences regarding the Initial December 21 Proposal.

Also on December 21, 2021, at the direction of Quidel senior management, representatives from Perella Weinberg prepared analyses of various cash and stock consideration alternatives, which were reviewed by Quidel senior management. Quidel senior management engaged in a series of communications with Citi regarding the availability of potential financing for the various consideration alternatives proposed by Perella Weinberg. Mr. Bryant participated in a series of teleconferences with Dr. Buechler regarding such analyses and the status of negotiations with Ortho.

Later on December 21, 2021, at a meeting of the Ortho board of directors that was attended by certain members of Ortho’s senior management and representatives from J.P. Morgan and Latham, J.P. Morgan provided a summary of the updated proposals made by Quidel on December 20, 2021 and December 21, 2021. The members of the Ortho board of directors discussed the Initial December 21 Proposal with J.P. Morgan and concluded that the deal was attractive, but that Ortho should continue to seek improved terms that include at least $1.75 billion in cash consideration and total implied value of $25 per share. The Ortho board of directors discussed the proposed fixed exchange ratio and possible alternative structures, such as a floating exchange ratio, or a cap or collar structure that could account for changes in the Quidel stock price prior to closing of the Combinations, potentially resulting in adjustments to the stock portion of the Ortho Scheme Consideration, but recognized that a fixed exchange ratio is the most common structure for stock merger transactions and offers certainty of relative ownership in the combined company (and resulting participation in anticipated synergies in the combined company), whereas such alternative structure negotiated for the Combinations would have been reciprocal, could have negatively impacted the value to be received by Ortho’s shareholders in the transaction (including the participation of Ortho’s shareholders in anticipated synergies in the combined company) and could have reduced certainty of closing of the Combinations if an additional termination right were negotiated as part of an alternative structure and would not be customary for transactions of this type. In addition, the Ortho board of directors acknowledged that the inclusion of a fixed amount of cash per share as a component of the overall consideration that Ortho shareholders would receive offered significant certainty in value to the Ortho shareholders.

Later on December 21, 2021, Mr. Bryant and Mr. Smith met telephonically and taking into account the consideration analyses prepared by Perella Weinberg, the financing availability evaluation provided by Citi and the discussions with members of the Quidel board of directors, and discussions with the Ortho board of directors, respectively, agreed in principle on the terms for the combination at an implied value of $24.75 per share based on Quidel’s closing stock price on December 21, 2021, consisting of $7.14 in cash and 0.1055 Topco Shares per Ortho Share (referred to in this joint proxy statement/prospectus as the “Ortho Scheme Consideration”).

238

On December 21, 2021, Ortho entered into an engagement letter with J.P. Morgan confirming the engagement of J.P. Morgan as its financial advisor.

On December 22, 2021, Mr. Bryant and Mr. Smith agreed in principle that the board of directors of the combined company would have 12 members, with four directors from Ortho and eight directors from Quidel.

On December 22, 2021, at a meeting of the Quidel board of directors that was attended by certain members of Quidel’s senior management and representatives from Perella Weinberg, Ms. Hodges provided an overview of the directors’ fiduciary duties in connection with their evaluation of the proposed transaction, and summarized the terms of the proposed transaction, as reflected in the BCA and the Stockholders Agreement. In the course of their deliberation, the Quidel board of directors reviewed a variety of materials, including the forecasts prepared by Quidel management and Ortho management, including the Ortho Synergies Estimates. The Quidel board of directors did not give any particular materials more weight than any other materials in its decision making process. Representatives of Perella Weinberg then reviewed with the Quidel board of directors Perella Weinberg’s financial analysis with respect to the Consideration of 0.1055 Topco Shares and $7.14 in cash per Ortho Share to be paid by Quidel pursuant to the BCA, taking into account the Quidel Exchange Ratio of one Topco Share per Quidel Share to be received by the Quidel stockholders in the Combinations and rendered an oral opinion, subsequently confirmed in writing, to the Quidel board of directors that, as of such date and based upon and subject to the various assumptions made, procedures followed, matters considered, and qualifications and limitations set forth therein, the consideration of 0.1055 Topco Shares and $7.14 in cash per Ortho Share to be paid by Quidel pursuant to the BCA was fair, from a financial point of view, to Quidel, taking into account the Quidel Exchange Ratio, as described in the section entitled “The Combinations—Opinion of Perella Weinberg Partners LP as Financial Advisor to Quidel” of this joint proxy statement/prospectus. Ms. Hodges then presented a set of proposed resolutions approving the BCA and the transactions contemplated thereby. On a motion duly made and seconded, the Quidel board of directors approved the resolutions by a unanimous vote.

Later on December 22, 2021, at a meeting of the Ortho board of directors that was attended by certain members of Ortho’s senior management and representatives from J.P. Morgan and Latham, representatives of J.P. Morgan summarized the current proposal of consideration equal to $7.14 in cash and 0.1055 Topco Shares per Ortho Share, which would represent an implied premium of 25% when compared to Ortho’s closing stock price on December 22, 2021. Representatives of J.P. Morgan then reviewed with the Ortho board of directors the strategic rationale for the transaction and their financial analysis with respect to the proposed consideration, and rendered an oral opinion, subsequently confirmed in writing that, subject to customary qualifications and as of such date, the consideration of $7.14 in cash and 0.1055 Topco Shares per Ortho Share was fair from a financial perspective to Ortho shareholders, as described in the section entitled “The Combinations—Opinion of J.P. Morgan Securities LLC as Financial Advisor to Ortho” of this joint proxy statement/prospectus. Representatives of Latham then summarized key terms of the BCA, Stockholders Agreement and Irrevocable Undertaking, and summarized fiduciary duties of the members of the Ortho board of directors as directors of a UK company. On a motion duly made and seconded, the Ortho board of directors approved the resolutions previously circulated to the directors by a unanimous vote, unanimously agreed that Mr. Smith and Robert Schmidt of Carlyle were authorized to approve final changes to the BCA and transaction documents, and then adjourned the meeting.

Later on December 22, 2021, Ortho and Quidel executed the BCA. Also on December 22, 2021, Carlyle executed its Irrevocable Undertaking and Carlyle, Ortho and Quidel executed the Stockholders Agreement.

On December 23, 2021, Quidel entered into an engagement letter with Citi confirming the engagement of Citi as its financial advisor.

On December 23, 2021, Ortho and Quidel issued a joint press release announcing the transaction.

Ortho Scheme Consideration to Ortho Shareholders

The BCA provides that, at the Ortho Effective Time, each Ortho Share issued and outstanding immediately prior to the Scheme Record Time (other than Ortho Shares that are held in treasury by Ortho, if any (each, an “Excluded Ortho Share”)), will be acquired by GTU Ops Inc. (a Computershare entity) or another company mutually acceptable to Quidel and Ortho and falling within Section 67(6) of the Finance Act 1986 (the “DR Nominee”) (or, if the DR Nominee holds the Ortho Shares today, transferred within the DR Nominee) on behalf and for the benefit of Topco in exchange for (a) 0.1055 Topco Shares and (b) $7.14 in cash (collectively, the “Ortho Scheme Consideration”). As of the Ortho Effective Time, holders of Ortho Shares (and any holders of depositary interests in Ortho Shares) shall cease to have any rights with respect to Ortho Shares, except their rights under the Ortho Scheme to receive the Ortho Scheme Consideration.

239

Quidel Reasons for the Combinations and Recommendation of the Quidel Board of Directors

The Quidel board of directors has determined that the Combinations, including the Quidel Merger and the other transactions contemplated by the BCA, are consistent with and will further the business strategies and goals of Quidel, and are in the best interests of Quidel and its stockholders. At its meeting on December 22, 2021, the Quidel board of directors (a) unanimously approved and declared advisable the BCA and Combinations, including the Quidel Merger and the transactions contemplated by the BCA, and (b) determined, subject to its duties under applicable law, to recommend that the Quidel stockholders adopt the BCA and the transactions contemplated by the BCA, including the Quidel Merger.

The Quidel board of directors recommends that Quidel stockholders vote:

| 1. | “FOR” the Merger Proposal;

| 2. | “FOR” the Advisory Merger Compensation Proposal;

| 3. | “FOR” the Adjournment Proposal;

| 4. | “FOR” the Election of Directors Proposal;

| 5. | “FOR” the Advisory Executive Compensation Proposal;

| 6. | “FOR” the Independent Registered Public Accounting Firm Proposal;

| 7. | “FOR” the Equity Incentive Plan Proposal; and

| 8. | “FOR” the ESPP Proposal.

The Quidel board of directors considered many factors in reaching its conclusion that the transactions contemplated by the BCA as a whole, including the Combinations, are fair to, and in the best interests of Quidel and its stockholders. In arriving at its conclusion, the Quidel board of directors consulted with Quidel’s management and its legal, financial and other advisors, reviewed a significant amount of information (including information prepared by its advisors) and considered the following factors in its deliberations:

Strategic Considerations. The Quidel board of directors believes that the Combinations present, and are expected to provide, a number of significant strategic opportunities and benefits to Quidel and its stockholders, including the following:

| • |  | the belief that the combined company will meet patient testing needs at all points of the care continuum, including reference labs, hospitals, physicians’ offices, urgent care centers and at-home / retail locations, due to the complementary nature of the companies’ products and markets;

| • |  | the belief that Ortho’s commercial team will better position and support a successful launch of Quidel’s new flagship product, the Savanna molecular platform, by providing access to more customers in the United States and worldwide;

| • |  | the belief that the transaction will accelerate development of a global commercial footprint for sales of other Quidel products by utilizing Ortho’s commercial teams, customer support, regulatory teams and other infrastructure across over 130 countries and provide accelerated international commercial opportunities for products such as Sofia;

| • |  | the belief that the transaction will provide immediate potential product development opportunities, including dry film technology expansion opportunities for Quidel’s point of care customers and immunoassay expansion opportunities for Ortho’s instruments, particularly given the strength of each company’s research and development capabilities;

| • |  | the belief that the combined company will unite world-class technologies and platforms to benefit customers with multiple modalities to address increasingly diverse clinical and customer needs and expanded access to clinical chemistry, immunoassay, molecular diagnostics, immunohematology, donor screening and point-of-care diagnostics offerings;

| • |  | the expectation that the transaction would provide Quidel with organic and inorganic expansion opportunities into significant new and emerging markets, including for continued diversification in telehealth technology and digital health;

| • |  | the belief that the transaction will position Quidel as a leader in the diagnostics industry, bringing together innovative, complementary products, solutions and services that enhance the health and well-being of patients

240

| across the globe, including a larger more broad-based company with greater flexibility to support our communities in their testing needs;

| • |  | the expectation that the combined company will realize approximately $90 million of run-rate cost-related synergies, excluding one-time costs, by the end of year three, driven primarily from operational efficiencies, supply chain optimization, and shared administrative functions, including public company costs, and has the potential to realize even greater synergies;

| • |  | the expectation that the transaction will generate strong cross-selling revenue synergies in excess of $100 million by 2025 and meaningful adjusted EBITDA benefits, which are expected to be driven by the enhanced global commercial reach and expansive product portfolio of the combined company;

| • |  | the expectation that the combined company will have improved talent attractiveness, offering more opportunities to employees functionally and globally;

| • |  | the cultural alignment between Quidel and Ortho, which both have talented and experienced employees who share a commitment to customers, patients and the communities the companies serve;

| • |  | the expectation that the transactions will result in a more diversified combined company with more stable and consistent revenue profile that can also continue to benefit from seasonal opportunities, and with a strong balance sheet with significant cash generation potential; and

| • |  | the belief that the transaction provides an attractive use of Quidel’s cash and presents significant potential growth and value creation.

Other Factors Considered by the Quidel Board of Directors. In addition to considering the strategic factors described above, the Quidel board of directors considered the following additional factors, all of which it viewed as supporting its decision to approve the Combinations and make its recommendations to Quidel stockholders:

| • |  | the fact that eight of the members of the 12-member Topco board of directors will be designated by Quidel, and that the committees of the Topco board of directors will be comprised of one director designated by Ortho and at least two directors designated by Quidel;

| • |  | the fact that Douglas Bryant, current President and Chief Executive Officer of Quidel, will serve as the Chief Executive Officer of Topco and Chair of the Topco board of directors and that Robert Bujarski, current Chief Operating Officer of Quidel, will serve as the President and Chief Operating Officer of Topco;

| • |  | the belief that the above-described governance matters would position the combined company for a successful integration process, future success and synergies realization;

| • |  | the fixed exchange ratio of one Ortho Share for 0.1055 Topco Shares, which, by its nature, would not adjust to compensate for increases or declines in the price of Ortho Shares prior to completion of the transaction;

| • |  | the fixed exchange ratio of one Quidel Share for one Topco Share, which, by its nature, would not adjust to compensate for increases or declines in the price of the Quidel Shares prior to completion of the Combinations;

| • |  | the fact that, based on the shares outstanding as of the date of the BCA, Quidel’s former stockholders will own approximately 62% of the combined company following completion of the Combinations and will continue to participate in potential appreciation in equity value of the combined company;

| • |  | the fact that, in certain circumstances, the Quidel board of directors has the right under the BCA to change its recommendation to Quidel stockholders that they adopt the BCA;

| • |  | its knowledge and understanding of the Quidel business, operations, financial condition, earnings, strategy, risks and future prospects;

| • |  | information and discussions with Quidel’s management regarding Ortho’s business, operations, financial condition, earnings, strategy and future prospects, and the results of Quidel’s due diligence review of Ortho;

| • |  | the current and prospective business environment in which Quidel and Ortho operate, including the impact of the COVID pandemic, international, national and local economic conditions, the competitive and regulatory environment, and the likely effect of these factors on Quidel and the combined company;

| • |  | the recommendation of Quidel’s senior management in favor of the Combinations;

241

| • |  | the financial analyses presented by Perella Weinberg to the Quidel board of directors and the opinion of Perella Weinberg delivered to the Quidel board of directors to the effect that, as of December 22, 2021, and based upon and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations set forth in Perella Weinberg’s written opinion, the Ortho Scheme Consideration of 0.1055 Topco Shares and $7.14 in cash per Ortho Share to be paid by Quidel pursuant to the BCA was fair, from a financial point of view, to Quidel, taking into account the Quidel Exchange Ratio of one Topco Share per Quidel Share, as more fully described in the section entitled “The Combinations—Opinion of Perella Weinberg Partners LP as Financial Advisor to Quidel” of this joint proxy statement/prospectus;

| • |  | the likelihood that the Combinations will be completed on a timely basis and the belief that antitrust clearance could be obtained without the imposition of conditions that would be materially adverse to the combined company;

| • |  | the fact that the Quidel Merger is subject to approval by the Quidel stockholders;

| • |  | the fact that, subject to certain limited exceptions, Ortho is prohibited from soliciting, participating in any discussions or negotiations with respect to, providing non-public information to any third party with respect to or entering into any agreement providing for, the acquisition of Ortho;

| • |  | the fact that Ortho may be required to pay Quidel a termination fee of approximately $46.9 million and/or reimburse Quidel for certain reasonable costs, fees and expenses it incurs if the BCA is terminated under certain circumstances specified in the BCA; and

| • |  | the fact that the Quidel Exchange Ratio will not be negatively affected in the event of a decrease in the share price of the Quidel Shares prior to the Quidel Effective Time and that the terms of the BCA do not include termination rights for Ortho triggered in the event of an increase of the value of Ortho relative to the value of Quidel.

The Quidel board of directors also considered the following specific aspects of the BCA:

| • |  | the representations and warranties of Ortho and Quidel, as well as the interim operating covenants requiring the parties to conduct their respective businesses in the ordinary course prior to completion of the Combinations, subject to specific limitations, which are generally reciprocal;

| • |  | the likelihood of consummation of the Combinations and the Quidel board of directors’ evaluation of the likely time period necessary to complete the Combinations;

| • |  | the nature of the closing conditions included in the BCA, including the exceptions to the events that would constitute a material adverse effect with respect to Ortho or Quidel for purposes of the BCA, as well as the likelihood of satisfaction of all conditions to consummation of the Combinations;

| • |  | Quidel’s right to engage in negotiations with, and provide information to, a third party that makes an unsolicited Acquisition Proposal for Quidel (as defined in the section entitled “The Business Combination Agreement—Acquisition Proposals” of this joint proxy statement/prospectus), if the Quidel board of directors determines in good faith, after consultation with its outside legal and financial advisors, that such proposal constitutes or would reasonably be expected to lead to, a Superior Proposal (as defined in the section entitled “The Business Combination Agreement—Acquisition Proposals” of this joint proxy statement/prospectus);

| • |  | the Quidel board of directors’ ability to change its recommendation that Quidel stockholders vote in favor of the adoption of the BCA if it determines in good faith after consultation with its outside counsel that failure to take such action would be inconsistent with its fiduciary duties under applicable law, subject to compliance by Quidel with certain obligations;

| • |  | the requirement for the parties to use reasonable best efforts to obtain all regulatory approvals or clearances;

| • |  | the restrictions in the BCA on Ortho’s ability to respond to and negotiate certain alternative transaction proposals from third parties and the requirement that Ortho pay Quidel an approximately $46.9 million termination fee if the BCA is terminated under certain circumstances;

| • |  | certain other provisions in the BCA, including the termination provisions; and

| • |  | the belief that the size of the termination fee that might be payable to Ortho pursuant to the BCA (i) was reasonable in light of the overall terms of the BCA, (ii) was within the range of termination fees in other transactions of this size and nature and (iii) would not be likely to preclude another party from making a competing proposal for Quidel.

242

The Quidel board of directors weighed these advantages and opportunities against a number of potentially negative factors in its deliberations concerning the BCA and the Combinations, including:

| • |  | the Ortho Exchange Ratio will not be reduced in the event of an increase in the share price of Quidel Shares prior to the Quidel Effective Time, and that the terms of the BCA do not include termination rights for Quidel triggered in the event of a decrease in the value of Ortho relative to the value of Quidel;

| • |  | the cash consideration payble to the Ortho shareholders by Quidel under the BCA is fixed and will not be reduced in the event of a decrease in the share price of Ortho Shares prior to the Effective Time;

| • |  | the potential that the fixed exchange ratio under the BCA could result in Quidel delivering greater value to the Ortho shareholders than had been anticipated by Quidel should the value of the Quidel Shares increase relative to Ortho Shares after the date of execution of the BCA;

| • |  | the significant costs to be incurred in connection with the Combinations, including the substantial cash and other costs required to integrate the businesses of Quidel and Ortho, as well as transaction expenses;

| • |  | the fact that projections of future results of operations and synergies are necessarily estimates based on assumptions, the risk of not realizing the estimates of synergies anticipated by Quidel’s management to result from the Combinations and cost savings between Quidel and Ortho, or that such benefits may take longer than expected to be realized, if at all;

| • |  | the difficulties inherent in the combination of two companies of the size and scope of Quidel and Ortho, including (i) challenges related to integrating and retaining management and employees and (ii) the possible diversion of management focus and resources from operational matters and other strategic opportunities for an extended period of time;

| • |  | the adverse impact that business uncertainty prior to the closing of the Combinations and during the post-closing integration period could have on the ability of both Quidel and Ortho to attract, retain and motivate key personnel;

| • |  | the potential adverse effect that the Combinations could have on Quidel’s business and relationships with employees, customers, suppliers, regulators and the communities in which it operates;

| • |  | the risk that governmental entities may not approve the Combinations or may impose conditions on Quidel or Ortho in order to gain approval for the Combinations that may adversely impact the ability of Topco to realize the estimates of synergies anticipated by Quidel’s management to result from the Combinations;

| • |  | the limited circumstances under which Quidel could terminate the BCA or refuse to consummate the Combinations;

| • |  | that Quidel, subject to customary exceptions, is prohibited during the term of the BCA from soliciting, participating in any discussions or negotiations with respect to, and providing nonpublic information to any third party with respect to, the acquisition of Quidel and that Quidel is prohibited from terminating the BCA to enter into any agreement providing for the acquisition of Quidel;

| • |  | that certain provisions of the BCA, although reciprocal, may have the effect of discouraging alternative proposals involving Quidel;

| • |  | the risk that, pursuant to the terms of the BCA, Quidel may become obligated to pay a termination fee of approximately $207.8 million and/or reimburse Ortho for certain reasonable costs, fees and expenses it incurs in certain circumstances;

| • |  | the generally reciprocal restrictions on operations until completion of the Combinations which could have the effect of preventing Quidel from pursuing certain other strategic transactions during the pendency of the BCA as well as taking certain other actions relating to the conduct of its business without the prior consent of Ortho;

| • |  | the fact that, if the Quidel board of directors effects a Change in Laguna Recommendation (as defined in the BCA) (a “Quidel Change in Recommendation”), Quidel will nonetheless be obligated to hold the Quidel Stockholders’ Meeting and submit the proposals described in this joint proxy statement/prospectus to its stockholders for their vote unless Quidel terminates the BCA or except in the case of a Quidel All Cash Superior Proposal;

| • |  | that failure to complete the Combinations could cause Quidel to incur significant fees and expenses and could lead to negative perceptions among investors, potential investors, customers and employees;

243

| • |  | the potential for litigation relating to the Combinations and the associated costs, time, burden and inconvenience involved in defending those proceedings;

| • |  | the risk that Ortho shareholders or Quidel stockholders, as applicable, may vote down the proposals at the Ortho Court Meeting or Quidel Stockholders’ Meeting; and

| • |  | the other risks of the type and nature described under the sections entitled “Risk Factors” and “Cautionary Statement Concerning Forward-Looking Statements” of this joint proxy statement/prospectus.

The Quidel board of directors concluded that the uncertainties, risks and potentially negative factors relevant to the Combinations were outweighed by the potential benefits that it expected Quidel and the Quidel stockholders would achieve as a result of the Combinations.

The foregoing discussion of the information and factors considered by the Quidel board of directors is not exhaustive but is intended to reflect the material factors considered by the Quidel board of directors in its consideration of the business combination with Ortho. In view of the large number of factors considered and their complexity, the Quidel board of directors, both individually and collectively, did not find it practicable to and did not attempt to quantify or assign any relative or specific weight to the various factors. Rather, the Quidel board of directors based its recommendation on the totality of the information presented to and considered by it. In addition, individual members of the Quidel board of directors may have given different weights to different factors. The foregoing discussion of the information and factors considered by the Quidel board of directors is forward-looking in nature. This information should be read in light of the factors described under the section entitled “Cautionary Statement Concerning Forward-Looking Statements” of this joint proxy statement/prospectus.

Ortho Reasons for the Combinations and Recommendation of the Ortho Board of Directors

The Ortho board of directors has determined, having consulted with J.P. Morgan, financial advisor to Ortho in connection with the Combinations, that the transactions contemplated by the BCA, including the Ortho Scheme, are fair to, and in the best interests of, Ortho and its shareholders. At its meeting on December 22, 2021, the Ortho board of directors, among other things, (a) determined that the Ortho Scheme and the transactions contemplated by the BCA as a whole are in the best interests of Ortho, would further the business goals and strategies of Ortho and would promote the success of Ortho for the benefit of its shareholders as a whole, (b) approved the terms of the BCA, including but not limited to the Ortho Scheme, (c) directed that the Ortho Scheme be recommended to Ortho’s shareholders and, subject to receiving the vote of Ortho shareholders, that the Ortho Scheme be approved and (d) approved the execution and delivery of the BCA by any director of Ortho.

The Ortho board of directors recommends that Ortho shareholders vote “FOR” each of the proposals at the Ortho Court Meeting and “FOR” each of the proposals at the Ortho General Meeting.

The Ortho board of directors considered many factors in reaching its conclusion that the transactions contemplated by the BCA as a whole, including the Combinations, are fair to, and in the best interests of Ortho and its shareholders. In arriving at its conclusion, the Ortho board of directors consulted with Ortho’s management and its legal, financial and other advisors, reviewed a significant amount of information and considered the following factors in its deliberations:

| • |  | the belief that the combination will result in the creation of a leader in the diagnostics industry with top-tier research and development capabilities, a more diverse product pipeline and a broader geographic footprint;

| • |  | the belief that Ortho’s and Quidel’s product and service offerings are highly complementary and provide opportunities to capture significant growth globally while enhancing cross-selling opportunities across a diversified customer and channel mix, including by enhancing the ability to meet patient needs at all points of the care continuum;

| • |  | the belief that Ortho and Quidel have complementary cultures and that their respective management teams will successfully integrate the two businesses after closing of the Combinations and provide a strong foundation for the combined management team to accelerate growth, stimulate the sharing of expertise and support faster innovation;

| • |  | the belief that the combination will accelerate innovative product expansion through complementary capabilities and product development synergies;

244

| • |  | the belief that the combination will allow Topco to achieve estimated cost synergies of $95 million by the end of the third year after closing of the Combinations, driven primarily by operational efficiencies, supply chain optimization and shared administrative functions, and cross-selling revenue synergies in excess of $100 million by 2025, as well as opportunities for adjusted EBITDA margin expansion, supporting enhanced cash generation;

These beliefs are based in part on the following factors that the Ortho board of directors considered:

| • |  | its knowledge and understanding of Ortho’s business, operations, financial condition, earnings, strategy and future prospects;

| • |  | information and discussions with Ortho’s management regarding Quidel’s business, operations, financial condition, earnings, strategy and future prospects, and the results of Ortho’s due diligence review of Quidel;

| • |  | the fact that one-third of the Topco board of directors following completion of the Combinations will be designated by Ortho;

| • |  | the fact that the Topco board of directors shall have an Audit Committee, a Nominating and Corporate Governance Committee and a Compensation Committee, each of which will include one director designated by Ortho at the closing of the Combinations;

| • |  | the fact that Joseph M. Busky, the current chief financial officer of Ortho, will be the chief financial officer of Topco and Michael Iskra, the current executive vice president of commercial excellence and strategy of Ortho, will be the chief commercial officer of Topco;

| • |  | the current and prospective economic climate generally and the competitive climate in the industries in which Ortho and Quidel operate, including the combination of certain other companies in such industries;

| • |  | the fact that, based on the shares outstanding as of the date of signing of the BCA, Ortho’s former shareholders will own approximately 38% of Topco following completion of the Combinations and will continue to participate in potential appreciation in the equity value of Topco;

| • |  | the financial analyses presented by J.P. Morgan and the oral opinion of J.P. Morgan delivered to the Ortho board of directors on December 22, 2021, which was confirmed by delivery of a written opinion, dated as of December 23, 2021, to the effect that, as of such date and based upon and subject to the assumptions made, procedures followed, matters considered and limitations on the review undertaken by J.P. Morgan in preparing its opinion, the Ortho Scheme Consideration was fair, from a financial point of view, to the holders of Ortho Shares, as more fully described below in the section entitled “Opinion of J.P. Morgan Securities LLC as Financial Advisor to Ortho” of this joint proxy statement/prospectus (with the full text of the written opinion of J.P. Morgan, dated as of December 23, 2021, which sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the review undertaken by J.P. Morgan in preparing its opinion, attached as Annex E to this joint proxy statement/prospectus and incorporated herein by reference);

| • |  | the review by the Ortho board of directors with its legal advisor of the structure of the proposed business combination transaction and the terms of BCA, including the conditions to their respective obligations and the termination provisions, as well as the likelihood of consummation of the Combinations and the Ortho board of directors’ evaluation of the likely time period necessary to complete the Combinations:

| • |  | the degree of mutuality and symmetry of representations, obligations and rights of the parties under the BCA, the conditions to each party’s obligation to close the transaction and the circumstances in which each party is permitted to terminate the BCA, and the likelihood that the Combinations will be completed on a timely basis and the belief that antitrust clearance could be obtained without the imposition of conditions that would be materially adverse to Topco;

| • |  | the nature of the closing conditions included in the BCA, including the exceptions to the events that would constitute a material adverse effect with respect to Ortho or Quidel for purposes of the BCA, as well as the likelihood of satisfaction of all conditions to consummation of the Combinations;

| • |  | Ortho’s right to engage in negotiations with, and provide information to, a third party that makes an unsolicited Acquisition Proposal for Ortho (as defined in the section entitled “The Business Combination Agreement—Acquisition Proposals” of this joint proxy statement/prospectus), if the Ortho board of directors determines in good faith, after consultation with its legal and financial advisors, that such proposal constitutes or would reasonably be expected to lead to a Superior Proposal (as defined in the section entitled “The Business Combination Agreement—Acquisition Proposals” of this joint proxy statement/prospectus);

245

| • |  | the Ortho board of directors’ ability to change its recommendation that Ortho shareholders vote in favor of the adoption of the BCA if it determines in good faith after consultation with its outside counsel that failure to take such action would be inconsistent with its fiduciary duties under applicable law, subject to compliance by Ortho with certain obligations;

| • |  | the right of Ortho to terminate the BCA if the Ortho board of directors makes a Change in Orca Recommendation (as defined in the BCA) (an “Ortho Change in Recommendation”) in response to a Superior Proposal for Ortho that includes only cash consideration, is fully financed and does not include any financing condition (an “Ortho All Cash Superior Proposal”), subject to certain requirements; and

| • |  | certain other provisions in the BCA, including the termination provisions;

| • |  | the fact that the Ortho Scheme is subject to approval by the Ortho shareholders;

| • |  | the fact that Carlyle Partners VI Cayman Holdings, L.P. (the “Carlyle Stockholder”) entered into a deed of irrevocable undertaking (as further described in the section entitled “Stockholders Agreement / Deed of Irrevocable Undertaking” of this joint proxy statement/prospectus), which requires the Carlyle Stockholder to vote its 118,106,000 Ortho Shares (representing approximately 49.79% of the Ortho Shares) in favor of the Combinations;

| • |  | the fact that, subject to certain limited exceptions, Quidel is prohibited from soliciting, participating in any discussions or negotiations with respect to, providing non-public information to any third party with respect to or entering into any agreement providing for, the acquisition of Quidel;

| • |  | the fact that Quidel may be required to pay Ortho a termination fee of approximately $208 million and/or reimburse Ortho for reasonable expenses it incurs if the BCA is terminated under certain circumstances specified in the BCA;

| • |  | the fact that the Ortho shareholders will receive $7.14 in cash for each Ortho Share, which significantly increases certainty in the value of the Ortho Scheme Consideration to Ortho shareholders, regardless of changes in the price of the Quidel Shares; and

| • |  | the fact that the Ortho Exchange Ratio of 0.1055 Topco Shares for each Ortho Share will not be reduced under the BCA in the event of a decrease in the share price of the Ortho Shares, or any increase in the price of Quidel Shares, prior to the Ortho Effective Time and that the terms of the BCA do not include termination rights for Quidel triggered in the event of an increase of the value of Quidel relative to the value of Ortho.

In making its determination, the Ortho board of directors also considered Ortho’s strategic alternatives to the proposed business combination with Quidel for maximizing shareholder value over the long-term, including the alternative of attempting to replicate the capabilities inherent in the proposed business combination by continuing as a standalone company or through an alternative business combination. In considering these alternatives, the Ortho board of directors weighed the potential risks, rewards and uncertainties associated with each and took into consideration the fact that, prior to the initial public offering of Ortho, Ortho’s financial advisors had explored alternative business combination opportunities and none were identified that were expected to be as attractive to Ortho and its shareholders as the Combinations. The Ortho board of directors concluded, based on its understanding of the business, assets, financial condition, results of operations, current business strategy, projections and prospects of Ortho, that the business combination transaction with Quidel was the best alternative reasonably available to Ortho.

The Ortho board of directors weighed these factors against the following uncertainties, risks and potentially negative factors relevant to the Combinations:

| • |  | the Ortho Exchange Ratio will not be increased under the BCA in the event of an increase in the share price of Ortho Shares, or a decrease in the share price of the Quidel Shares prior to the Ortho Effective Time, and the terms of the BCA do not include termination rights for Ortho triggered in the event of a decrease in the value of Quidel relative to the value of Ortho;

| • |  | the potential that the fixed exchange ratio under the BCA could result in greater value to the Quidel stockholders than had been anticipated by Ortho should the market value of the Ortho Shares increase relative to Quidel Shares after the date of execution of the BCA;

| • |  | the adverse impact that business uncertainty prior to the closing of the Combinations and during the post-closing integration period could have on the ability of both Ortho and Quidel to attract, retain and motivate key personnel;

246

| • |  | the challenges inherent in the combination of two business enterprises of the size and scope of Ortho and Quidel, including (a) the possible diversion of management focus and resources from operational matters and other strategic opportunities for an extended period of time and (b) difficulties in integrating and retaining management and employees;

| • |  | the fact that projections of future results of operations and synergies are necessarily estimates based on assumptions, the risk of not realizing the estimates of synergies anticipated by Ortho’s management to result from the Combinations and cost savings between Ortho and Quidel and the risk that other anticipated benefits might not be realized;

| • |  | the substantial costs to be incurred in connection with the transaction, including the substantial cash and other costs of integrating the businesses of Ortho and Quidel, as well as transaction expenses;

| • |  | that failure to complete the Combinations could cause Ortho to incur significant fees and expenses and could lead to negative perceptions among investors, potential investors and customers;

| • |  | the potential effect of the transaction on Ortho’s business and relationships with employees, customers, suppliers, regulators and the communities in which it operates;

| • |  | the risk that governmental entities may not approve the transaction, or may impose conditions on Ortho or Quidel in order to gain approval for the transaction that may adversely impact the ability of Topco to realize the estimates of synergies anticipated by Ortho’s management to result from the Combinations;

| • |  | the limited circumstances under which Ortho could terminate the BCA or refuse to consummate the Combinations;

| • |  | that Ortho, subject to customary exceptions, is prohibited during the term of the BCA from soliciting, participating in any discussions or negotiations with respect to, and providing non-public information to any third party with respect to, the acquisition of Ortho and that, subject to limited exceptions in response to an Ortho All Cash Superior Proposal, Ortho may not terminate the BCA to enter into any agreement providing for the acquisition of Ortho;

| • |  | the risk that, pursuant to the terms of the BCA, Ortho may become obligated to pay a termination fee of approximately $47 million and/or reimburse Quidel for certain reasonable costs, fees and expenses it incurs in certain circumstances;

| • |  | the generally reciprocal restrictions on operations until completion of the Combinations which could have the effect of preventing Ortho from pursuing certain other strategic transactions during the pendency of the BCA as well as taking certain other actions relating to the conduct of its business without the prior consent of Quidel;

| • |  | the fact that, if the Ortho board of directors effects an Ortho Change in Recommendation, subject to limited exceptions in response to an Ortho All Cash Superior Proposal, Ortho will nonetheless be unable to terminate the BCA and will be obligated to hold the Ortho Shareholder Meetings and submit the proposals described in this joint proxy statement/prospectus to its shareholders for their vote unless Quidel terminates the BCA;

| • |  | the fact that the deed of irrevocable undertaking entered into by the Carlyle Stockholder will remain in effect after an Ortho Change in Recommendation such that the Carlyle Stockholder would still be required to vote in favor of the Combinations, notwithstanding the Ortho Change in Recommendation;

| • |  | the possibility that the transaction might not be completed, or that completion might be unduly delayed, for reasons beyond either party’s control and the potential negative impact that may have on each party’s business and relationships with employees, customers, suppliers, regulators and the communities in which it operates;

| • |  | the fact that, if the Combinations are completed, the Ortho Scheme will bind all Ortho shareholders, including those who did not vote to approve the Scheme Proposal at the Ortho Court Meeting;

| • |  | the fact that, after announcement of the Combinations, the share price of Ortho Shares is expected to be influenced by the pendency of the Combinations and, in that context, changes in the share price of Quidel Shares, the perceived likelihood of completion of the Combinations and the anticipated performance of Topco after the Combinations could impact the price of Ortho Shares, in addition to the performance of Ortho as a standalone company;

| • |  | the potentially differing interests of Ortho directors and executive officers with respect to the consummation of the Combinations, including in connection with (a) the continued engagement and/or employment of such directors

247

| and executive officers, (b) the continued positions of certain of such directors as directors on the Topco board of directors and (c) the treatment in the Combinations of equity awards held by Ortho directors and executive officers; and

| • |  | the risks of the type and nature described under the sections entitled “Risk Factors” and “Cautionary Statement Concerning Forward-Looking Statements” of this joint proxy statement/prospectus.

The Ortho board of directors concluded that the uncertainties, risks and potentially negative factors relevant to the Combinations were outweighed by the potential benefits that it expected Ortho and the Ortho shareholders would achieve as a result of the Combinations.

The foregoing discussion of the information and factors considered by the Ortho board of directors is not exhaustive but is intended to reflect the material factors considered by the Ortho board of directors in its consideration of the business combination with Quidel. In view of the large number of factors considered and their complexity, the Ortho board of directors, both individually and collectively, did not find it practicable to and did not attempt to quantify or assign any relative or specific weight to the various factors. Rather, the Ortho board of directors based its recommendation on the totality of the information presented to and considered by it. In addition, individual members of the Ortho board of directors may have given different weights to different factors. The foregoing discussion of the information and factors considered by the Ortho board of directors is forward-looking in nature. This information should be read in light of the factors described under the sections entitled “Cautionary Statement Concerning Forward-Looking Statements” and “Risk Factors” of this joint proxy statement/prospectus.

Opinion of Perella Weinberg Partners LP as Financial Advisor to Quidel

Quidel retained Perella Weinberg to act as its financial advisor in connection with the Combinations. Quidel selected Perella Weinberg based on its qualifications, expertise and reputation and its knowledge of the business and affairs of Quidel and the industry in which Quidel conducts its businesses. Perella Weinberg, as part of its investment banking business, is continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, leveraged buyouts and other transactions as well as for corporate and other purposes.

On December 22, 2021, Perella Weinberg rendered its oral opinion, subsequently confirmed in writing, to the Quidel board of directors that, as of such date and based upon and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations set forth therein, the Ortho Scheme Consideration of 0.1055 Topco Shares and $7.14 in cash per Ortho Share to be paid by Quidel pursuant to the BCA was fair, from a financial point of view, to Quidel, taking into account the Quidel Exchange Ratio of one Topco Share per Quidel Share.

The full text of Perella Weinberg’s written opinion, dated December 22, 2021, which sets forth, among other things, the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by Perella Weinberg in preparing its opinion, is attached hereto as Annex D and is incorporated herein by reference. Holders of Quidel Shares should read the opinion carefully and in its entirety. Perella Weinberg’s opinion does not address Quidel’s underlying business decision to enter into the BCA or the relative merits of the Combinations as compared with any other strategic alternative that may be available to Quidel. Perella Weinberg was not authorized to solicit, and did not solicit, indications of interest in a transaction with Quidel from any party. Perella Weinberg’s opinion was not intended to be and does not constitute a recommendation to any holder of Quidel Shares or Ortho Shares, or any other person, as to how such person should vote or otherwise act with respect to the Combinations or any other matter. Perella Weinberg’s opinion does not in any manner address the prices at which the Quidel Shares, the Ortho Shares or the Topco Shares will trade at any time. In addition, Perella Weinberg expressed no opinion as to the fairness of the Combinations to, or any consideration received in connection with the Combinations by, the holders of any other class of securities, creditors or other constituencies of Quidel. Perella Weinberg provided its opinion for the information and assistance of the Quidel board of directors in connection with, and for the purposes of its evaluation of, the Combinations. The summary of the written opinion of Perella Weinberg is qualified in its entirety by reference to the full text of the written opinion attached as Annex D to this joint proxy statement/prospectus.

In connection with rendering its opinion and performing its related financial analyses, Perella Weinberg, among other things:

| • |  | reviewed certain publicly available financial statements and other business and financial information with respect to Quidel and Ortho, including equity research analyst reports;

248

| • |  | reviewed certain internal financial statements, analyses and forecasts, including sensitivities thereto (the “Quidel Management Projections for Quidel”), and other financial and operating data relating to the business of Quidel, in each case, prepared by management of Quidel (as set forth in “Unaudited Forward-Looking Financial Information—Quidel Unaudited Forward-Looking Financial Information”);

| • |  | reviewed certain internal financial statements, analyses and forecasts (the “Ortho Management Projections for Ortho”), and other financial and operating data relating to the business of Ortho, in each case, prepared by management of Ortho and approved for Perella Weinberg’s use by management of Quidel (as set forth in “Unaudited Forward-Looking Financial Information—Ortho Unaudited Forward-Looking Financial Information”);

| • |  | reviewed certain internal financial statements, analyses and forecasts (the “Quidel Management Projections for Ortho”) relating to the business of Ortho prepared by management of Quidel (as set forth in “Unaudited Forward-Looking Financial Information—Quidel Unaudited Forward-Looking Financial Information”);

| • |  | reviewed the Quidel Synergies Estimates (as defined below);

| • |  | discussed the past and current business, operations, financial condition and prospects of Quidel, including the Quidel Synergies Estimates, with the management and other representatives of Quidel, and discussed the past and current business, operations, financial condition and prospects of Ortho with the management and other representatives of Quidel;

| • |  | reviewed the relative financial contributions of Quidel and Ortho to the future financial performance of Topco on a pro forma basis;

| • |  | compared the financial performance of Quidel and Ortho with that of certain other publicly traded companies which Perella Weinberg believed to be generally relevant;

| • |  | compared the financial terms of the proposed Combinations with the publicly available financial terms of certain transactions which Perella Weinberg believed to be generally relevant;

| • |  | reviewed the historical trading prices and trading activity for the Quidel Shares and Ortho Shares, and compared such prices and trading activity of the Quidel Shares and Ortho Shares with those of securities of certain other publicly traded companies which Perella Weinberg believed to be generally relevant;

| • |  | participated in discussions among representatives of Quidel and Ortho and their respective advisors;

| • |  | reviewed a draft, dated December 22, 2021, of the BCA; and

| • |  | conducted such other financial studies, analyses and investigations, and considered such other factors, as Perella Weinberg deemed appropriate.

In arriving at its opinion, Perella Weinberg assumed and relied upon, without independent verification, the accuracy and completeness of the financial and other information supplied or otherwise made available to it (including information that was available from generally recognized public sources) for purposes of its opinion and further relied upon the assurances of the management of Quidel that, to their knowledge, the information furnished, or approved for Perella Weinberg’s use, by them for purposes of Perella Weinberg’s analysis did not contain any material omissions or misstatements of material fact. With respect to the Quidel Management Projections for Quidel, Perella Weinberg was advised by the management of Quidel, and assumed, with the consent of the Quidel board of directors, that they were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of Quidel as to the future stand-alone financial performance of Quidel and the other matters covered thereby. Perella Weinberg expressed no view as to the assumptions on which the Quidel Management Projections for Quidel were based. With respect to the Ortho Forecasts, Perella Weinberg assumed, with the consent of the Quidel board of directors, that they were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of Ortho as to the future stand-alone financial performance of Ortho and the other matters covered thereby and Perella Weinberg expressed no view as to the assumptions on which they were based. With respect to the Quidel Management Projections for Ortho, Perella Weinberg assumed, with the consent of the Quidel board of directors, that they were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of Quidel as to the future standalone financial performance of Ortho and the other matters covered thereby and Perella Weinberg expressed no view as to the assumptions on which they were based. Perella Weinberg assumed, with the consent of the Quidel board of directors, that the Quidel Synergies Estimates and potential strategic implications and operational benefits (including the amount, timing and achievability thereof) anticipated by management of Quidel to result from the Combinations will be realized in the amounts

249

and at the times projected by management of Quidel, and Perella Weinberg expressed no view as to the assumptions on which they were based. Perella Weinberg relied without independent verification upon the assessment by the management of Quidel of the timing and risks associated with the integration of Quidel and Ortho. In arriving at its opinion, Perella Weinberg did not make any independent valuation or appraisal of the assets or liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of Quidel or Ortho, nor was it furnished with any such valuations or appraisals. Perella Weinberg did not assume any obligation to conduct, nor did it conduct, any physical inspection of the properties or facilities of Quidel or Ortho. In addition, Perella Weinberg did not evaluate the solvency of any party to the BCA (or the impact of the Combinations thereon), including under any applicable laws relating to bankruptcy, insolvency or similar matters. Perella Weinberg assumed that the final executed BCA would not differ from the form of the BCA that it reviewed in any respect material to its analysis, and that the Combinations would be consummated in accordance with the terms set forth in the BCA, without modification, waiver or delay in any respect material to its analysis. Perella Weinberg also assumed that the Quidel Merger and Ortho Scheme, taken together as a single integrated transaction, would qualify as an exchange described under Section 351 of the Code and that the Quidel Merger will also qualify as a “reorganization” within the meaning of Section 368(a) of the Code. In addition, Perella Weinberg assumed that in connection with the receipt of all the necessary approvals for the Combinations, no delays, limitations, conditions or restrictions would be imposed that could have an adverse effect on Quidel, Ortho or the contemplated benefits expected to be derived in the Combinations, in each case, in any way meaningful to its analysis. Perella Weinberg relied upon the advice of counsel as to all legal matters relevant to rendering its opinion.

Perella Weinberg’s opinion addressed only the fairness from a financial point of view, as of the date thereof, of the Ortho Scheme Consideration of 0.1055 Topco Shares and $7.14 in cash per Ortho Share provided for in the BCA to Quidel taking into account the Quidel Exchange Ratio of one Topco Share per Quidel Share. Perella Weinberg was not asked to, and it did not, offer any opinion as to any other term of the BCA or any other document contemplated by or entered into in connection with the BCA, the form, structure or financing of the Combinations or the likely timeframe in which the Combinations would be consummated. In addition, Perella Weinberg expressed no opinion as to the fairness of the amount or nature of any compensation to be received by any officers, directors or employees of any parties to the BCA, or any class of such persons, whether relative to the Ortho Scheme Consideration of 0.1055 Topco Shares and $7.14 in cash per Ortho Share provided for in the BCA or otherwise. Perella Weinberg did not express any opinion as to any tax or other consequences that may result from the transactions contemplated by the BCA or any related document, nor did its opinion address any legal, tax, regulatory or accounting matters, as to which it understood Quidel had received such advice as it deemed necessary from qualified professionals. Perella Weinberg’s opinion did not address the underlying business decision of Quidel to enter into the BCA or the relative merits of the Combinations as compared with any other strategic alternative which may have been available to Quidel. Perella Weinberg was not authorized to solicit, and did not solicit, indications of interest in a transaction with Quidel from any party.

Perella Weinberg’s opinion was necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to it as of, the date of its opinion. It should be understood that subsequent developments may affect Perella Weinberg’s opinion and the assumptions used in preparing it, and Perella Weinberg does not have any obligation to update, revise, or reaffirm its opinion. The issuance of Perella Weinberg’s opinion was approved by a fairness opinion committee of Perella Weinberg.

Summary of Material Financial Analyses

The following is a summary of the material financial analyses performed by Perella Weinberg and reviewed with the Quidel board of directors in connection with Perella Weinberg’s opinion and does not purport to be a complete description of the financial analyses performed by Perella Weinberg. The order of analyses described below does not represent the relative importance or weight given to those analyses by Perella Weinberg. Some of the summaries of the financial analyses include information presented in tabular format. In order to fully understand Perella Weinberg’s financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Perella Weinberg’s financial analyses.

For purposes of its analyses, Perella Weinberg calculated that the Ortho Scheme Consideration of 0.1055 Topco Shares and $7.14 in cash per Ortho Share had an implied value of $24.75 per Ortho Share based upon the closing price of Quidel Shares on December 21, 2021.

250

Historical Stock Trading

Perella Weinberg reviewed the historical intraday market prices for each of the Quidel Shares and the Ortho Shares for the 52-week period ended on December 21, 2021 (the last trading day prior to the Quidel board of directors’ meeting approving the execution of the BCA). Perella Weinberg noted that the range of low and high intraday prices of the Quidel Shares during the 52-week period ended on December 21, 2021 was $103.31 to $265.00 and that the range of low and high closing prices of the Ortho Shares during the period commencing with Ortho’s initial public offering on January 28, 2021 and ended on December 21, 2021 was $15.14 to $22.99. Perella Weinberg also reviewed the historical intraday market prices of the Quidel Shares and the Ortho Shares for the six-month period ended December 21, 2021, which ranged from $109.75 to $180.06 per Quidel Share and from $17.34 to $22.86 per Ortho Share. Perella Weinberg compared these ranges to the closing price of $166.94 per Quidel Share and the closing price of $19.49 per Ortho Share on December 21, 2021 and to the implied value of $24.75 per Ortho Share in the Combinations.

Perella Weinberg then calculated the exchange ratio range implied by the 52-week historical stock trading review. Perella Weinberg calculated (i) the ratio of the highest intraday market price of the Ortho Shares (less $7.14 per share) to the lowest intraday market price of the Quidel Shares and (ii) the ratio of the lowest intraday market price of the Ortho Shares (less $7.14 per share) to the highest intraday market price of the Quidel Shares to derive a range of implied exchange ratios of 0.0302x to 0.1534x. Perella Weinberg compared this implied exchange ratio range to the exchange ratio of 0.1055 Topco Shares per Ortho Share provided for in the BCA. Perella Weinberg noted that the exchange ratio implied by the closing prices of the Ortho Shares and the Quidel Shares on December 21, 2021 (after deducting $7.14 per Ortho Share) was 0.0740x and that the range of such implied exchange ratios for the 90-day period ended on December 21, 2021 was 0.0690x to 0.1046x.

Equity Research Analyst Price Target Statistics

Perella Weinberg observed the most recent publicly available research analyst price targets for the Quidel Shares prepared and published by four selected equity research analysts prior to December 21, 2021. Perella Weinberg noted that the range of these recent equity analyst price targets for Quidel Shares was $74.23 to $203.21 per share, in each case as discounted to December 31, 2021 using an 8.0% cost of equity.

Perella Weinberg also observed the most recent publicly available research analyst price targets for the Ortho Shares prepared and published by six selected equity research analysts prior to December 21, 2021. Perella Weinberg noted that the range of these recent equity analyst price targets for the Ortho Shares was $23.20 to $29.69 per share, in each case as discounted to December 31, 2021 using an 8.0% cost of equity.

Perella Weinberg compared these ranges to the closing price of $166.94 per Quidel Share and the closing price of $19.49 per Ortho Share on December 21, 2021 and to the implied value of $24.75 per Ortho Share in the Combinations.

Perella Weinberg then calculated the exchange ratio range implied by the equity research analyst price target review. Perella Weinberg calculated the ratios of (i) the highest most recently publicly available research analyst price target for the Ortho Shares (discounted to December 31, 2021 using an 8.0% cost of equity less $7.14 per share) to the lowest most recently publicly available research analyst price target for Quidel Shares (discounted to December 31, 2021 using an 8.0% cost of equity) and (ii) the lowest most recently publicly available research analyst price target for the Ortho Shares (discounted to December 31, 2021 using an 8.0% cost of equity less $7.14 per share) to the highest most recently publicly available research analyst price target for Quidel Shares (discounted to December 31, 2021 using an 8.0% cost of equity) to derive an implied exchange ratio range of 0.0790x to 0.3038x. Perella Weinberg compared this implied exchange ratio range to the exchange ratio of 0.1055 Topco Shares per Ortho Share provided for in the BCA. Perella Weinberg noted that the exchange ratio implied by the closing prices of the Ortho Shares and the Quidel Shares on December 21, 2021 (after deducting $7.14 per Ortho Share) was 0.0740x and that the range of such implied exchange ratios for the 90-day period ended on December 21, 2021 was 0.0690x to 0.1046x.

The public market trading prices published by equity research analysts do not necessarily reflect current market trading prices for Quidel Shares or the Ortho Shares. Further, these estimates are subject to uncertainties, including the future financial performance of Quidel and Ortho and future market conditions, and the public market trading price targets published by these equity research analysts represent price targets to be achieved over a 12 month period.

Selected Publicly Traded Companies Analysis

Perella Weinberg reviewed and compared certain financial information for Quidel and Ortho with corresponding financial information, ratios and public market multiples for nine publicly held companies in the diagnostics industry described below (the “Selected Publicly Traded Companies”). Although none of the following companies is identical to Quidel or Ortho, Perella Weinberg selected these companies because they had publicly traded equity securities and were deemed to be similar to Quidel and Ortho in one or more respects, including operating in the diagnostics and life sciences industry, and engaged in the development, manufacture and sale of instruments and reagents used by clinical laboratories, healthcare providers, life science researchers, and the pharmaceutical industry. Perella Weinberg selected the companies used in the analysis on the basis of its experience and knowledge of companies in the industry and various factors, including the size of the company (companies with enterprise values greater than $5 billion), the similarity of the lines of business to Quidel and Ortho’s lines of business (development, manufacture and sale of instruments and reagents used by clinical laboratories, healthcare providers, life science researchers and the pharmaceutical industry), as well as the business models, technology, service offerings and end-market exposure of such companies.

For Quidel, Ortho and each of the Selected Publicly Traded Companies, Perella Weinberg calculated and compared financial information and various financial market multiples and ratios based on company filings for historical information and consensus third-party research estimates from FactSet. Perella Weinberg also calculated such information, multiples and ratios for the combined company based upon both (a) the Ortho Forecasts and Quidel Management Projections for Quidel (using the Case 1 projections as described below under “Unaudited Forward-Looking Financial Information—Quidel Unaudited Forward-Looking Financial Information”) and (b) consensus third-party research estimates.

With respect to Quidel, Ortho and each of the Selected Publicly Traded Companies, Perella Weinberg reviewed enterprise value (“EV”) as of December 21, 2021 as a multiple of both estimated revenue for the calendar year 2022 (“2022E Revenue”) and estimated earnings before interest, taxes, depreciation and amortization (“EBITDA”) for (i) the calendar year 2022 (“2022E EBITDA”) and (ii) the calendar year 2023 (“2023E EBITDA”). The results of these analyses are summarized in the following table:

Selected Publicly Traded Companies |  | EV/2022E Revenue |  |  | EV/2022E EBITDA |  |  | EV/2023E EBITDA |
Thermo Fisher Scientific Inc. |  |  | 7.1x |  |  |  | 25.7x |  |  |  | 23.8x |
Abbott Laboratories |  |  | 6.3x |  |  |  | 21.8x |  |  |  | 19.9x |
Danaher Corporation |  |  | 8.3x |  |  |  | 24.3x |  |  |  | 23.2x |
Sysmex Corporation |  |  | 7.4x |  |  |  | 26.7x |  |  |  | 24.4x |
Bio-Rad Laboratories, Inc. |  |  | 3.1x |  |  |  | 14.0x |  |  |  | 12.5x |
Hologic, Inc. |  |  | 5.5x |  |  |  | 15.2x |  |  |  | 14.7x |
bioMérieux SA |  |  | 4.3x |  |  |  | 17.1x |  |  |  | 16.4x |
Qiagen N.V. |  |  | 7.1x |  |  |  | 19.1x |  |  |  | 17.5x |
DiaSorin S.p.A. |  |  | 8.1x |  |  |  | 23.0x |  |  |  | 21.4x |
Median |  |  | 7.1x |  |  |  | 21.8x |  |  |  | 19.9x |
Quidel |  |  | 7.1x |  |  |  | 15.2x |  |  |  | 29.6x |
Ortho |  |  | 3.3x |  |  |  | 12.1x |  |  |  | 11.4x |
Newco (Consensus) |  |  | 4.5x |  |  |  | 15.6x |  |  |  | 18.2x |
Newco (Ortho Forecasts/Quidel Management Projections for Quidel (Case 1)) |  |  | 4.2x |  |  |  | 15.6x |  |  |  | 12.8x |

Based on the analysis of the relevant metrics described above and on professional judgments made by Perella Weinberg, Perella Weinberg selected and applied a range of multiples of 3.0x to 4.0x to 2022E Revenue of Ortho using both consensus third-party research estimates and the Ortho Forecasts and a range of 4.5x to 6.0x to 2022E Revenue of Quidel using consensus third-party research estimates and the Quidel Management Projections for Quidel (using the Case 1 Estimates as described below under “Unaudited Forward-Looking Financial Information—Quidel Unaudited Forward-Looking Financial Information”). Further, based on the analysis of the relevant metrics described above and on professional judgments made by Perella Weinberg, Perella Weinberg applied a range of 12.0x to 16.0x to 2022E EBITDA of Ortho using consensus third-party research estimates and the Ortho Forecasts and a range of 12.0x to 14.0x to 2022E EBITDA of Quidel using consensus third-party research estimates and the Quidel Management Projections for Quidel (using the Case 1 Estimates as described below under “Unaudited Forward-Looking Financial Information—Quidel Unaudited Forward-Looking Financial Information”). For purposes of this analysis utilizing the Ortho Forecasts, Perella Weinberg used 2022E EBITDA for Ortho

252

of approximately $538 million as provided by management of Ortho. From these analyses, Perella Weinberg derived ranges of implied equity values for each of Ortho and Quidel. Perella Weinberg calculated implied values per share by dividing the implied equity values by the applicable fully diluted shares (based upon the number of issued and outstanding shares and other equity interests in each case provided by the managements of Ortho and Quidel, as applicable, and using the treasury method for calculation of option dilution). The ranges of implied values per share derived from these calculations are summarized in the following table:

|  | Metric |  | Implied Value Range Per Share
Ortho |  |  |  |
Consensus Estimates |  | 2022E Revenue |  | $17.31 - $25.63
|  | 2022E EBITDA |  | $19.25 - $28.21
Ortho Forecasts |  | 2022E Revenue |  | $18.11 - $26.70
|  | 2022E EBITDA |  | $18.16 - $26.76
Quidel |  |  |  |
Consensus Estimates |  | 2022E Revenue |  | $109.89 - $142.46
|  | 2022E EBITDA |  | $134.17 - $154.50
Quidel Management Projections for Quidel (Case 1) |  | 2022E Revenue |  | $123.71 - $160.88
|  | 2022E EBITDA |  | $132.44 - $152.48

Perella Weinberg compared these ranges to the closing price of $166.94 Quidel Share and the closing price of $19.49 per Ortho Share on December 21, 2021 and to the implied value of $24.75 per Ortho Share in the Combinations.

Perella Weinberg then calculated the exchange ratio ranges implied by the Selected Publicly Traded Companies analysis consensus third-party research estimates. For each of the foregoing analyses, Perella Weinberg calculated (i) the ratio of the highest implied value per Ortho Share (less $7.14 per share) to the lowest implied value per Quidel Share and (ii) the ratio of the lowest implied value per Ortho Share (less $7.14 per share) to the highest implied value per Quidel Share, in each case as derived from the Selected Publicly Traded Companies analysis. The following table sets forth the results of this analysis:

|  | Metric |  | Implied Exchange Ratio Range
Consensus Estimates |  | 2022E Revenue |  | 0.0714x - 0.1682x
|  | 2022E EBITDA |  | 0.0784x - 0.1570x

Perella Weinberg compared these implied exchange ratio ranges to the exchange ratio of 0.1055 Topco Shares per Ortho Share provided for in the BCA. Perella Weinberg noted that the exchange ratio implied by the closing prices of the Ortho Shares and the Quidel Shares on December 21, 2021 (after deducting $7.14 per Ortho Share) was 0.0740x and that the range of such implied exchange ratios for the 90-day period ended on December 21, 2021 was 0.0690x to 0.1046x.

Although the Selected Publicly Traded Companies were used for comparison purposes, no business of any selected company was either identical or directly comparable to Ortho’s or Quidel’s business. Perella Weinberg’s comparison of Selected Publicly Traded Companies to Ortho and Quidel and analysis of the results of such comparisons were not purely mathematical, but instead necessarily involved complex considerations and judgments concerning differences in financial and operating characteristics and other factors that could affect the relative values of the Selected Publicly Traded Companies, Ortho and Quidel.

Selected Transactions Analysis

Using publicly available information, Perella Weinberg reviewed the financial terms of the selected precedent transactions described below (the “Selected Transactions”) involving companies that operated in, or were exposed to, the diagnostics industry announced between May 2011 and April 2021. Perella Weinberg selected these transactions in the exercise of its professional judgment and experience because Perella Weinberg deemed them to be most similar in size, scope and impact on the industry to Ortho or otherwise relevant to the Combinations.

253

For each of the Selected Transactions, Perella Weinberg calculated and compared the resulting EV in the transaction as a multiple of (i) revenue over the last 12 months (“LTM Revenue”) publicly reported prior to the announcement of the transaction (“EV/LTM Revenue”) and (ii) EBITDA over the last 12 months (“LTM EBITDA”) publicly reported prior to the announcement of the transaction (“EV/LTM EBITDA”).

The following table lists the Selected Transactions and summarizes the observed EV/LTM Revenue and EV/LTM EBITDA multiples:

|  |  |  |  |  | EV / LTM |
Announcement Date |  | Target |  | Acquiror |  | Revenue Multiple |  |  | EBITDA Multiple (1) |
April 2021 |  | Luminex Corporation |  | DiaSorin S.p.A. |  |  | 4.1x |  |  |  | 21.2x |
March 2021 |  | GenMark Diagnostics, Inc. |  | Roche Holding Ltd |  |  | 10.4x |  |  |  | Not Meaningful |
January 2021 |  | Oxford Immunotec Global PLC |  | PerkinElmer, Inc. |  |  | 7.3x |  |  |  | Not Meaningful |
June 2017 |  | EUROIMMUN US, Inc. |  | PerkinElmer, Inc. |  |  | 5.0x |  |  |  | 22.6x |
September 2016 |  | Cepheid |  | Danaher Corporation |  |  | 7.1x |  |  |  | Not Meaningful |
February 2016 |  | Alere Inc. |  | Abbott Laboratories |  |  | 3.2x |  |  |  | 25.1x |
September 2013 |  | BioFire Diagnostics, LLC |  | bioMérieux SA |  |  | 6.9x |  |  |  | NA |
July 2012 |  | One Lambda, Inc. |  | Thermo Fisher Scientific Inc. |  |  | 5.1x |  |  |  | 10.9x |
April 2012 |  | Gen-Probe Incorporated |  | Hologic, Inc. |  |  | 6.4x |  |  |  | 20.3x |
May 2011 |  | Phadia AB |  | Thermo Fisher Scientific Inc. |  |  | 6.7x |  |  |  | 16.6x |
|  |  |  | Median |  |  | 6.6x |  |  |  | 20.7x |
|  |  |  | Mean |  |  | 6.2x |  |  |  | 19.4x |

(1) | EV/EBITDA multiples less than 0.0x or greater than 100.0x were deemed to be not meaningful for the analysis.

Based on the multiples of enterprise value to LTM Revenue and LTM EBITDA described above, Perella Weinberg’s analyses of the various Selected Transactions and on professional judgments made by Perella Weinberg with respect to, among other things, the financial performance and competitive positioning of Ortho and the target companies in the Selected Transactions, Perella Weinberg applied a range of multiples of 5.0x to 7.0x to Ortho’s estimated 2021 revenue based on consensus third-party research estimates to derive a range of implied values of approximately $33.17 to $49.49 per Ortho Share and a range of multiples of 16.0x to 20.0x to Ortho’s estimated 2021 EBITDA based on consensus third-party research estimates to derive a range of implied values of approximately $27.19 to $35.90 per Ortho Share. Perella Weinberg compared these ranges to the closing price of $19.49 per Ortho Share on December 21, 2021 and to the implied value of $24.75 per Ortho Share in the Combinations.

Although the Selected Transactions were used for comparison purposes, none of the Selected Transactions nor the companies involved in them was either identical or directly comparable to the Combinations or Ortho.

Discounted Cash Flow Analysis

Ortho

Perella Weinberg conducted a discounted cash flow analyses for Ortho based on the Ortho Forecasts, the Quidel Management Projections for Ortho and consensus third-party research estimates by:

| • |  | calculating the present value as of December 31, 2021 of the estimated standalone unlevered free cash flows that Ortho could generate for fiscal year 2022 through fiscal year 2026 using discount rates ranging from 7.0% to 8.0% based on estimates of the weighted average cost of capital of Ortho derived using the Capital Asset Pricing Model (referred to as “CAPM”),

| • |  | adding terminal values calculated using perpetuity growth rates ranging from 2.0% to 3.0% and discounted using rates ranging from 7.0% to 8.0%, and

| • |  | adding the present value of the benefit of the utilization of net operating losses as provided by management of Ortho discounted using a rate of 7.5%.

The range of perpetuity growth rates was estimated by Perella Weinberg utilizing its professional judgment and experiences, taking into account the Ortho Forecasts and market expectations regarding long-term real growth of gross domestic product

254

and inflation. Perella Weinberg also cross-checked such estimates of perpetuity growth rates against the EBITDA multiples implied by such growth rates and a range of discount rates to be applied to Ortho’s future unlevered cash flow forecasts.

Perella Weinberg used a range of discount rates from 7.0% to 8.0% derived by application of the CAPM, which takes into account certain company-specific metrics, including Ortho’s target capital structure, the cost of long-term debt, forecasted tax rate and predicted (Barra) beta, as well as certain financial metrics for the United States financial markets generally.

From the range of implied enterprise values, Perella Weinberg derived ranges of implied equity values for Ortho. To calculate the implied equity value from the implied enterprise value, Perella Weinberg added cash and cash equivalents of $289 million and subtracted net debt of $2.283 billion as of December 31, 2021 as estimated by Ortho management. Perella Weinberg calculated implied value per share by dividing the implied equity value by the fully diluted shares (using the treasury method). Perella Weinberg performed the same analyses taking into account the present value, using a discount rate of 7.5%, of (i) approximately $88 million of annual run rate cost synergies by the end of the third year following the Combinations, as estimated by management of Ortho and Quidel to result from the Combinations, with illustrative 3% annual growth for two years thereafter and assuming costs to achieve such synergies equal to the run-rate cost synergies spread over two years and (ii) approximately $105 million of annual run-rate revenue synergies by the end of the fourth year following the Combinations, as estimated by management of Quidel to result from the Combinations, with illustrative 8.2% annual growth for one year thereafter and assuming approximately 50% margin contribution from revenue synergies.

These analyses resulted in the following reference ranges of implied equity value per Ortho Share:

|  | Range of Implied Present Value Per Share
|  | Without Quidel Synergies Estimates |  | With Quidel Synergies Estimates
Ortho Forecasts |  | $24.94 – 38.42 |  | $31.59-48.36
Quidel Management Projections for Ortho |  | $24.41-$37.68 |  | $31.06 - $47.62
Consensus Estimates |  | $25.11 - $38.87 |  | $31.76 - $48.82

Perella Weinberg compared these ranges to the closing price of $19.49 per Ortho Share on December 21, 2021 and to the implied value of $24.75 per Ortho Share in the Combinations.

Quidel

Perella Weinberg conducted discounted cash flow analyses for Quidel based on the Quidel Management Projections for Quidel (using both the Case 1 Estimates and Case 2 Estimates as described below under “Unaudited Forward-Looking Financial Information—Quidel Unaudited Forward-Looking Financial Information”) and consensus third-party research estimates by:

| • |  | calculating the present value as of December 31, 2021 of the estimated standalone unlevered free cash flows that Quidel could generate for fiscal year 2022 through fiscal year 2026 using discount rates ranging from 7.0% to 8.0% based on estimates of the weighted average cost of capital of Quidel derived using the CAPM, and

| • |  | adding terminal values calculated using perpetuity growth rates ranging from 2.0% to 3.0% and discounted using rates ranging from 7.0% to 8.0%.

The range of perpetuity growth rates was estimated by Perella Weinberg utilizing its professional judgment and experiences, taking into account the Quidel Management Projections for Quidel and market expectations regarding long-term real growth of gross domestic product and inflation. Perella Weinberg also cross-checked such estimates of perpetuity growth rates against the EBITDA multiples implied by such growth rates and a range of discount rates to be applied to Quidel’s future unlevered cash flow forecasts.

Perella Weinberg used a range of discount rates from 7.0% to 8.0% derived by application of the CAPM, which takes into account certain company-specific metrics, including Quidel’s target capital structure, the cost of long-term debt, forecasted tax rate and predicted (Barra) beta, as well as certain financial metrics for the United States financial markets generally.

From the range of implied enterprise values, Perella Weinberg derived ranges of implied equity values for Quidel. To calculate the implied equity value from the implied enterprise value, Perella Weinberg added cash and cash equivalents of

255

$862 million and subtracted debt of $1 million and net non-operating liabilities of $85 million, as of December 31, 2021 as estimated by management of Quidel. Perella Weinberg calculated implied value per share by dividing the implied equity value by the fully diluted shares (using the treasury method).

These analyses resulted in the following reference ranges of implied equity value per Quidel Share:

|  | Range of Implied Equity Values
Quidel Management Projections for Quidel (Case 1) |  | $200.49 - $280.56
Quidel Management Projections for Quidel (Case 2) |  | $171.74 - $238.98
Consensus Estimates |  | $93.33 - $122.00

Perella Weinberg compared these ranges to the closing price of $166.94 per Quidel Share on December 21, 2021.

Perella Weinberg then calculated (i) the ratio of the highest implied value per Ortho Share (less $7.14 per share) to the lowest implied value per Quidel Share and (ii) the ratio of the lowest implied value per Ortho Share (less $7.14 per share) to the highest implied value per Quidel Share, in each case as derived from these reference ranges of implied equity value per Ortho Share and per Quidel Share. Perella Weinberg derived ranges of implied exchange ratios as set forth in the following table:

|  | Range of Implied Exchange Ratios
Ortho Forecasts/Quidel Management Projections for Quidel (Case 1) |  | 0.0635x – 0.1560x
Quidel Management Projections for Ortho/Quidel Management Projections for Quidel (Case 2) |  | 0.0723x – 0.1778x
Consensus Estimates |  | 0.1473x – 0.3400x

Perella Weinberg compared these implied exchange ratio ranges to the exchange ratio of 0.1055 Topco Shares per Ortho Share provided for in the BCA. Perella Weinberg noted that the exchange ratio implied by the closing prices of the Ortho Shares and the Quidel Shares on December 21, 2021 (after deducting $7.14 per Ortho Share) was 0.0740x and that the range of such implied exchange ratios for the 90-day period ended on December 21, 2021 was 0.0690x to 0.1046x.

Miscellaneous

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth herein, without considering the analyses or the summary as a whole, could create an incomplete view of the processes underlying Perella Weinberg’s opinion. In arriving at its fairness determination, Perella Weinberg considered the results of all of its analyses and did not attribute any particular weight to any factor or analysis considered. Rather, Perella Weinberg made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. No company or transaction used in the analyses described herein as a comparison is directly comparable to Quidel, Ortho or the Combinations.

Perella Weinberg prepared the analyses described herein for purposes of providing its opinion to the Quidel board of directors as to the fairness, from a financial point of view, as of the date of such opinion, of the Ortho Scheme Consideration of 0.1055 Topco Shares and $7.14 in cash per Ortho Share provided for in the BCA to Quidel taking into account the Quidel Exchange Ratio of one Topco Share per Quidel Share. These analyses do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold. Perella Weinberg’s analyses were based in part upon the Quidel Management Projections for Quidel, the Ortho Forecasts, the Quidel Management Projections for Ortho and third-party research analyst estimates, which are not necessarily indicative of actual future results, and which may be significantly more or less favorable than suggested by Perella Weinberg’s analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties to the BCA or their respective advisors, none of Quidel, Ortho, Perella Weinberg or any other person assumes responsibility if future results are materially different from those forecasted by the Quidel or Ortho management or third parties.

As described above, the opinion of Perella Weinberg to the Quidel board of directors was one of many factors taken into consideration by the Quidel board of directors in making its determination to approve the Combinations. Perella Weinberg

256

was not asked to, and did not, recommend the specific consideration provided for in the BCA, which consideration was determined through arms-length negotiations between Quidel and Ortho. Perella Weinberg did not recommend any specific amount of consideration to the stockholders of Quidel or the Quidel board of directors or that any specific amount of consideration constituted the only appropriate consideration for the Combinations. Also, as discussed above, Perella Weinberg’s opinion was not intended to be and does not constitute a recommendation to any holder of Quidel Shares or Ortho Shares, or any other person, as to how such person should vote or otherwise act with respect to the proposed Combinations or any other matter and does not in any manner address the prices at which the Quidel Shares, the Ortho Shares or the Topco Shares will trade at any time.

Perella Weinberg has acted as financial advisor to Quidel in connection with the Combinations and, pursuant to the terms of the engagement letter between Perella Weinberg and Quidel, dated November 19, 2021, Quidel agreed to pay Perella Weinberg $5,000,000 upon the rendering of Perella Weinberg’s opinion (which amount would have also become payable if Perella Weinberg had determined that it was not able to deliver its opinion) and an additional fee of $25,000,000, which is contingent upon the consummation of the Combinations. In addition, Quidel agreed to reimburse Perella Weinberg for certain expenses that may arise, and to indemnify Perella Weinberg for certain liabilities and other items that may arise, out of its engagement by Quidel.

During the two-year period prior to the date of its opinion, no material relationship existed between Perella Weinberg and its corporate advisory affiliates and Ortho pursuant to which compensation was received by Perella Weinberg or its corporate advisory affiliates. In the past, Perella Weinberg and its corporate advisory affiliates have provided financial advisory services unrelated to the Combinations to The Carlyle Group, a controlling shareholder of Ortho, or its affiliates pursuant to which Perella Weinberg has received fees of approximately $8.33 million within the two-year period prior to the date of its opinion. In the past, Perella Weinberg and its affiliates have provided financial advisory and other financial services to Quidel and its affiliates unrelated to the Combinations, for which it has received no compensation within the two-year period prior to the date of its opinion. Perella Weinberg and its corporate advisory affiliates may in the future provide investment banking and other financial services to Quidel, Ortho, The Carlyle Group and their respective affiliates and in the future may receive compensation for the rendering of such services. In the ordinary course of its business activities, Perella Weinberg or its affiliates may at any time hold long or short positions, and may trade or otherwise effect transactions, for its own account or the accounts of customers or clients, in debt or equity or other securities (or related derivative securities) or financial instruments (including bank loans or other obligations) of Quidel, Ortho, The Carlyle Group or any of their respective affiliates.

Opinion of J.P. Morgan Securities LLC as Financial Advisor to Ortho

Pursuant to an engagement letter, Ortho retained J.P. Morgan as its financial advisor in connection with the Combinations.

At the meeting of the Ortho board of directors on December 22, 2021, J.P. Morgan rendered its oral opinion to the Ortho board of directors that, as of such date and based upon and subject to the assumptions made, procedures followed, matters considered and limitations on the review undertaken by J.P. Morgan in preparing its opinion, the Ortho Scheme Consideration was fair, from a financial point of view, to the holders of Ortho Shares. J.P. Morgan confirmed its December 22, 2021 oral opinion by delivering its written opinion, dated December 23, 2021, to the Ortho board of directors that, as of such date, the Ortho Scheme Consideration was fair, from a financial point of view, to the holders of Ortho Shares.

The full text of the written opinion of J.P. Morgan, dated December 23, 2021, which sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the review undertaken by J.P. Morgan in preparing its opinion, is attached as Annex E to this joint proxy statement/prospectus and is incorporated herein by reference. The summary of the opinion of J.P. Morgan set forth in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of such opinion. Holders of Ortho Shares are urged to read the opinion in its entirety. J.P. Morgan’s opinion was addressed to the Ortho board of directors (in its capacity as such) in connection with and for the purposes of its evaluation of the Combinations, was directed only to the Ortho Scheme Consideration and did not address any other aspect of the Combinations. J.P. Morgan expressed no opinion as to the fairness of the Ortho Scheme Consideration to the holders of any other class of securities, creditors or other constituencies of Ortho or as to the underlying decision by Company to engage in the Combinations. The issuance of J.P. Morgan’s opinion was approved by a fairness committee of J.P. Morgan. The opinion does not constitute a recommendation to any shareholder of Ortho as to how such shareholder should vote with respect to the Combinations or any other matter.

257

In arriving at its opinion, J.P. Morgan, among other things:

| • |  | reviewed the Business Combination Agreement;

| • |  | reviewed certain publicly available business and financial information concerning Ortho and Quidel and the industries in which they operate;

| • |  | compared the financial and operating performance of Ortho and Quidel with publicly available information concerning certain other companies J.P. Morgan deemed relevant and reviewed the current and historical market prices of Ortho Shares and Quidel Shares and certain publicly traded securities of such other companies;

| • |  | reviewed certain internal financial analyses and forecasts prepared by the management of Ortho relating to its business and Quidel’s business, as well as the estimated amount and timing of cost savings and related expenses and synergies expected to result from the Combinations; and

| • |  | performed such other financial studies and analyses and considered such other information as J.P. Morgan deemed appropriate for the purposes of its opinion.

In addition, J.P. Morgan held discussions with certain members of the management of Ortho and Quidel with respect to certain aspects of the Combinations, and the past and current business operations of Ortho and Quidel, the financial condition and future prospects and operations of Ortho, Quidel and Topco, the effects of the Combinations on the financial condition and future prospects of Ortho, Quidel and Topco, and certain other matters J.P. Morgan believed necessary or appropriate to its inquiry.

In giving its opinion, J.P. Morgan relied upon and assumed the accuracy and completeness of all information that was publicly available or was furnished to or discussed with J.P. Morgan by Ortho and Quidel or otherwise reviewed by or for J.P. Morgan. J.P. Morgan did not independently verify any such information or its accuracy or completeness, and pursuant to its engagement letter with Ortho, J.P. Morgan did not assume any obligation to undertake any such independent verification. J.P. Morgan did not conduct and was not provided with any valuation or appraisal of any assets or liabilities, nor did J.P. Morgan evaluate the solvency of Ortho, Quidel or Topco under any state or federal laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to J.P. Morgan or derived therefrom, including the Ortho Management Projections for Ortho, the Ortho Management Projections for Quidel (each as defined in the section below entitled “Ortho Unaudited Forward-Looking Financial Information”) and the Ortho Synergies Estimates (as defined below) J.P. Morgan assumed that they were reasonably prepared based on assumptions reflecting the best currently available estimates and judgments by management as to the expected future results of operations and financial condition of Ortho and Quidel to which such analyses or forecasts relate. J.P. Morgan expressed no view as to such analyses or forecasts (including the Ortho Synergies Estimates) or the assumptions on which they were based. J.P. Morgan also assumed that the Combinations and the other transactions contemplated by the Business Combination Agreement will qualify as a tax-free reorganization for United States federal income tax purposes and will be consummated as described in the Business Combination Agreement and this Joint Proxy Statement/Prospectus. J.P. Morgan also assumed that the representations and warranties made by Ortho and Quidel in the Business Combination Agreement and the related agreements were and will be true and correct in all respects material to its analysis. J.P. Morgan is not a legal, regulatory or tax expert and relied on the assessments made by advisors to Ortho with respect to such issues. J.P. Morgan further assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Combinations will be obtained without any adverse effect on Ortho, Quidel or Topco or on the contemplated benefits of the Combinations, in each case, that would be material to its analysis.

The Ortho Management Projections for Ortho and the Ortho Management Projections for Quidel furnished to J.P. Morgan were prepared by the management of Ortho as discussed below more fully under the section entitled “Unaudited Forward-Looking Financial Information”. Ortho does not publicly disclose internal management projections of the type provided to J.P. Morgan in connection with J.P. Morgan’s analysis of the Combinations, and such projections were not prepared with a view toward public disclosure. These projections were based on numerous variables and assumptions that are inherently uncertain and may be beyond the control of Ortho’s management, including, without limitation, factors related to general economic and competitive conditions and prevailing interest rates. Accordingly, actual results could vary significantly from those set forth in such projections. For more information regarding the use of projections and other forward-looking statements, please refer to the section below entitled “Ortho Unaudited Forward-Looking Financial Information.”

J.P. Morgan’s opinion was necessarily based on economic, market and other conditions as in effect on, and the information made available to J.P. Morgan as of, the date of such opinion. J.P. Morgan’s opinion noted that subsequent developments

258

may affect J.P. Morgan’s opinion and that J.P. Morgan does not have any obligation to update, revise, or reaffirm such opinion. J.P. Morgan’s opinion is limited to the fairness, from a financial point of view, of the Ortho Scheme Consideration, and J.P. Morgan has expressed no opinion as to the fairness of any consideration to be paid in connection with the Combinations to the holders of any other class of securities, creditors or other constituencies of Ortho or as to the underlying decision by Ortho to engage in the Combinations. Furthermore, J.P. Morgan expressed no opinion with respect to the amount or nature of any compensation to any officers, directors, or employees of any party to the Combinations, or any class of such persons relative to the Ortho Scheme Consideration or with respect to the fairness of any such compensation. J.P. Morgan expressed no opinion as to the price at which Ortho Shares, Quidel Shares or shares of Topco Common Stock will trade at any future time.

J.P. Morgan was not authorized to and did not solicit any expressions of interest from any other parties with respect to the sale of all or any part of Ortho or any other alternative transaction.

The terms of the Business Combination Agreement were determined through arm’s length negotiations between Ortho and Quidel, and the decision to enter into the Business Combination Agreement was solely that of the Ortho board of directors and the Board of Directors of Quidel. J.P. Morgan’s opinion and financial analyses were only one of the many factors considered by the Ortho board of directors in its evaluation of the Combinations and should not be viewed as determinative of the views of the Ortho board of directors or its management with respect to the Combinations or the Ortho Scheme Consideration.

In accordance with customary investment banking practice, J.P. Morgan employed generally accepted valuation methodologies in rendering its opinion to the Ortho board of directors on December 22, 2021 and in the financial analysis presented to the Ortho board of directors on such date in connection with the rendering of such opinion. The following is a summary of the material financial analyses utilized by J.P. Morgan in connection with rendering its opinion to the Ortho board of directors and does not purport to be a complete description of the analyses or data presented by J.P. Morgan. Some of the summaries of the financial analyses include information presented in tabular format. The tables are not intended to stand alone, and in order to more fully understand the financial analyses used by J.P. Morgan, the tables must be read together with the full text of each summary. Considering the data set forth below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of J.P. Morgan’s analyses.

Public Trading Multiples

Using publicly available information, J.P. Morgan compared selected financial data of Ortho and Quidel with similar data for selected publicly traded companies engaged in businesses which J.P. Morgan judged to be sufficiently analogous to those engaged in by Ortho and Quidel, as applicable.

The companies selected by J.P. Morgan with respect to Ortho were as follows:

| • |  | Avantor, Inc.

| • |  | PerkinElmer, Inc.

| • |  | Bio-Rad Laboratories, Inc.

| • |  | Hologic, Inc.

| • |  | BioMerieux SA

| • |  | Grifols SA

| • |  | Qiagen NV

| • |  | DiaSorin S.p.A.

The companies selected by J.P. Morgan with respect to Quidel were as follows:

| • |  | Avantor, Inc.

| • |  | PerkinElmer, Inc.

| • |  | Bio-Rad Laboratories, Inc.

259

| • |  | Hologic, Inc.

| • |  | BioMerieux SA

| • |  | Grifols SA

| • |  | Qiagen NV

| • |  | DiaSorin S.p.A.

| • |  | 10X Genomics, Inc.

| • |  | NanoString Technologies Inc.

These companies were selected by J.P. Morgan based on its experience and familiarity with Ortho’s and Quidel’s industry, because of similarities in one or more of their business characteristics and, in certain cases, similarities to Ortho and Quidel, as applicable, based on certain operational characteristics and/or certain financial metrics. However, certain of these companies may have characteristics that are materially different from those of Ortho and Quidel, as applicable. The analyses necessarily involve complex considerations and judgments concerning differences in financial and operational characteristics of the companies involved and other factors that could affect the selected companies differently than they would affect Ortho and Quidel, as applicable.

Using publicly available information, J.P. Morgan calculated, for each selected company, the ratios of the company’s firm value (“FV”) to the consensus equity research analyst estimates for the company’s adjusted earnings before interest, taxes, depreciation and amortization post-stock based compensation (“Adj. EBITDA”) for the year ending December 31, 2022 (the “FV/2022E Adj. EBITDA”).

Selected Publicly Traded Companies |  | FV/2022E Adj. EBITDA |
Avantor, Inc. |  |  | 20.1x |
PerkinElmer, Inc. |  |  | 24.1x |
Bio-Rad Laboratories, Inc. |  |  | 12.0x |
Hologic, Inc. |  |  | 15.2x |
BioMerieux SA |  |  | 17.2x |
Grifols SA |  |  | 14.0x |
Qiagen NV |  |  | 19.1x |
DiaSorin S.p.A. |  |  | 22.0x |
10X Genomics, Inc. |  |  | N/M | 1
NanoString Technologies Inc. |  |  | N/M | 1

1 | Not meaningful

Based on the results of this analysis, J.P. Morgan selected a reference range of 12.0x – 24.0x for FV/2022E Adj. EBITDA for Ortho and a reference range of 12.0x – 22.0x for FV/2022E Adj. EBITDA for Quidel. After applying such ranges to the projected Adj. EBITDA for Ortho and Quidel for the twelve month period ending December 31, 2022, as set forth in the Ortho Management Projections for Ortho and the Ortho Management Projections for Quidel, as applicable, the analysis indicated the following ranges of implied per share equity value (rounded to the nearest $0.25) for Ortho Shares and Quidel Shares:

|  | Implied Per Share Equity Value |
|  | Low |  |  | High |
Ortho FV/2022E Adj. EBITDA |  | $ | 20.50 |  |  | $ | 48.50 |
Quidel FV/2022E Adj. EBITDA |  | $ | 165.50 |  |  | $ | 287.75 |

The ranges of implied per share equity values for Ortho Shares and Quidel Shares were compared to the closing share prices of Ortho Shares of $19.49 and Quidel Shares of $166.94 on December 21, 2021, the trading day immediately preceding the date on which J.P. Morgan rendered its oral opinion.

260

Discounted Cash Flow Analysis

J.P. Morgan conducted a discounted cash flow analysis for the purpose of determining an implied fully diluted equity value per share for Ortho Shares and Quidel Shares. J.P. Morgan calculated the unlevered free cash flows that Ortho and Quidel are expected to generate during fiscal years 2022E through 2026E (as set forth in the Ortho Management Projections for Ortho and the Ortho Management Projections for Quidel, as applicable, described in the section entitled “Ortho Unaudited Forward-Looking Financial Information,” which were discussed with, and approved by, the Ortho board of directors for use by J.P. Morgan in connection with its financial analyses). J.P. Morgan also calculated a range of terminal values for Ortho and Quidel at the end of this period by applying perpetual growth rates ranging from 2.0% to 3.0%, to estimates of the unlevered terminal free cash flows for each of Ortho and Quidel at the end of fiscal-year 2026E, as provided in the Ortho Management Projections for Ortho and the Ortho Management Projections for Quidel, as applicable. J.P. Morgan then discounted the unlevered free cash flow estimates and the range of terminal values to present value as of December 31, 2021 using discount rates ranging from 6.5% to 7.5% for Ortho, and 7.5% to 8.5% for Quidel, which ranges were chosen by J.P. Morgan based upon an analysis of the weighted average cost of capital of Ortho and Quidel, respectively. The present value of the unlevered free cash flow estimates and the range of terminal values were then adjusted by subtracting net debt for each of Ortho and Quidel as of December 31, 2021, and for Ortho, by adding the value of Ortho’s net operating losses as provided by the management of Ortho.

Based on the foregoing, this analysis indicated the following ranges of implied per share equity value for Ortho Shares and Quidel Shares (rounded to the nearest $0.25):

|  | Implied Per Share Equity Value |
|  | Low |  |  | High |
Ortho Discounted Cash Flow |  | $ | 24.00 |  |  | $ | 40.00 |
Quidel Discounted Cash Flow |  | $ | 175.50 |  |  | $ | 240.75 |

The ranges of implied per share equity values for Ortho Shares and Quidel Shares were compared to the closing share prices of Ortho Shares of $19.49 and Quidel Shares of $166.94 on December 21, 2021, the trading day immediately preceding the date on which J.P. Morgan rendered its oral opinion.

Relative Value Analysis

J.P. Morgan compared the results for Ortho to the results for Quidel with respect to the public trading multiples and discounted cash flow analyses described above. J.P. Morgan compared the lowest equity value per share for Ortho to the highest equity value per share for Quidel to derive the lowest exchange ratio implied by each pair of results. J.P. Morgan also compared the highest equity value per share for Ortho to the lowest equity value per share for Quidel to derive the highest exchange ratio implied by each pair of results. The ranges of implied exchange ratios resulting from this analysis (adjusted to reflect cash consideration of $7.14 per share) were:

|  | Implied Exchange Ratios |
|  | Low |  |  | High |
FV/2022E Adj. EBITDA |  |  | 0.0463x |  |  |  | 0.2491x |
Discounted Cash Flow |  |  | 0.0697x |  |  |  | 0.1875x |

The ranges of implied exchange ratios resulting from the foregoing analysis were compared to (i) the implied exchange ratio (adjusted to reflect cash consideration of $7.14 per share) of 0.0740x on December 21, 2021, the trading day immediately preceding the date on which J.P. Morgan rendered its opinion, and (ii) the stock consideration per Ortho Share of 0.1055x, as contemplated in the Business Combination Agreement.

Value Creation Analysis

J.P. Morgan conducted an analysis of the theoretical value creation to the existing holders of Ortho Shares that compared the estimated implied equity value of Ortho Shares and Quidel Shares on a standalone basis, based on the midpoint value determined in J.P. Morgan’s discounted cash flow analyses described above, to the estimated implied equity value of the ownership in the combined company of former holders of Ortho Shares, pro forma for the Combinations.

261

J.P. Morgan calculated the pro forma implied equity value of Ortho Shares by (1) adding the sum of (a) the implied equity value of Ortho on a stand-alone basis of approximately $7,276 million, using the midpoint value determined in J.P. Morgan’s discounted cash flow analysis of Ortho described above, (b) the implied equity value of Quidel on a stand-alone basis of approximately $8,652 million, using the midpoint value determined in J.P. Morgan’s discounted cash flow analysis of Quidel described above, and (c) the estimated value of the Ortho Synergies Estimates, as reflected in estimates Ortho’s management provided to J.P. Morgan for use in connection with its analysis, in the aggregate amount of approximately $2,176 million, (2) subtracting (a) the cash consideration to be paid to the holders of Ortho Shares in connection with the Combinations, in the aggregate amount of approximately $1,750 million and (b) estimated transaction expenses, in an aggregate amount of approximately $180 million, as estimated by J.P. Morgan and approved by the management of Ortho and (3) multiplying such result by the pro forma equity ownership of the combined company by the existing holders of Ortho Shares of approximately 37.7%. This analysis indicated that the Combinations implied equity value of the Topco Shares received by the holders of Ortho Shares of approximately $6,095 million, which, when combined with the cash consideration paid to the holders of Ortho Shares, represents accretion in value of approximately $569 million, or 7.8%, compared to the estimated standalone equity value of Ortho Shares. There can be no assurance, however, that the implied Ortho Synergies Estimates, transaction-related expenses and other impacts referred to above will not be substantially greater or less than those estimated by Ortho’s management and described above.

Miscellaneous

The foregoing summary of certain material financial analyses does not purport to be a complete description of the analyses or data presented by J.P. Morgan. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. J.P. Morgan believes that the foregoing summary and its analyses must be considered as a whole and that selecting portions of the foregoing summary and these analyses, without considering all of its analyses as a whole, could create an incomplete view of the processes underlying the analyses and its opinion. As a result, the ranges of valuations resulting from any particular analysis or combination of analyses described above were merely utilized to create points of reference for analytical purposes and should not be taken to be the view of J.P. Morgan with respect to the actual value of Ortho or Quidel. The order of analyses described does not represent the relative importance or weight given to those analyses by J.P. Morgan. In arriving at its opinion, J.P. Morgan did not attribute any particular weight to any analyses or factors considered by it and did not form an opinion as to whether any individual analysis or factor (positive or negative), considered in isolation, supported or failed to support its opinion. Rather, J.P. Morgan considered the totality of the factors and analyses performed in determining its opinion.

Analyses based upon forecasts of future results are inherently uncertain, as they are subject to numerous factors or events beyond the control of the parties and their advisors. Accordingly, forecasts and analyses used or made by J.P. Morgan are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by those analyses. Moreover, J.P. Morgan’s analyses are not and do not purport to be appraisals or otherwise reflective of the prices at which businesses actually could be acquired or sold. None of the selected companies reviewed as described in the above summary is identical to Ortho or Quidel. However, the companies selected were chosen because they are publicly traded companies with operations and businesses that, for purposes of J.P. Morgan’s analysis, may be considered similar to those of Ortho and Quidel. The analyses necessarily involve complex considerations and judgments concerning differences in financial and operational characteristics of the companies involved and other factors that could affect the companies compared to Ortho and Quidel.

As a part of its investment banking business, J.P. Morgan and its affiliates are continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, investments for passive and control purposes, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. J.P. Morgan was selected to advise Ortho with respect to the Combinations and deliver an opinion to Ortho’s board of directors with respect to the Combinations on the basis of, among other things, such experience and its qualifications and reputation in connection with such matters and its familiarity with Ortho and the industries in which it operates.

Ortho has agreed to pay J.P. Morgan a fee of up to $50 million (but not less than $40 million), $3 million of which became payable to J.P. Morgan at the time J.P. Morgan delivered its opinion and the remainder of which is contingent and payable upon the consummation of the Combinations. In addition, Ortho has agreed to reimburse J.P. Morgan for certain of its expenses incurred in connection with its services, including the fees and disbursements of counsel, and will indemnify J.P. Morgan against certain liabilities arising out of J.P. Morgan’s engagement.

262

During the two years preceding the date of J.P. Morgan’s opinion, J.P. Morgan and its affiliates have had commercial or investment banking relationships with Ortho for which J.P. Morgan and such affiliates have received customary compensation. Such services during such period have included acting as joint lead bookrunner on offerings of debt securities of Ortho subsidiaries in May 2020 and January 2020, and joint lead bookrunner on offerings of Ortho’s equity securities in September 2021 and January 2021. During the two years preceding the date of J.P. Morgan’s opinion, J.P. Morgan and its affiliates have had commercial or investment banking relationships with The Carlyle Group Inc. (“Carlyle”), Ortho’s approximately 50% shareholder, for which J.P. Morgan and such affiliates have received customary compensation. Such services during such period have included acting as joint lead bookrunner on an offering of debt securities of a Carlyle subsidiary in May 2021. In addition, during the two years preceding the date of J.P. Morgan’s opinion, J.P. Morgan and its affiliates have had commercial or investment banking relationships with Carlyle portfolio companies for which J.P. Morgan and such affiliates have received customary compensation. Such services during such period have included providing debt syndication, equity underwriting, debt underwriting and financial advisory services to Carlyle portfolio companies. J.P. Morgan’s commercial banking affiliate is an agent bank and a lender under outstanding credit facilities of Carlyle and Carlyle portfolio companies for which it receives customary compensation or other financial benefits. During the two years preceding the date of J.P. Morgan’s opinion, neither J.P. Morgan nor its affiliates have had any material financial advisory or other material commercial or investment banking relationships with Quidel. In addition, J.P. Morgan and its affiliates hold, on a proprietary basis, less than 1% of the outstanding common shares of each of Ortho, Carlyle and Quidel. In the ordinary course of their businesses, J.P. Morgan and its affiliates may actively trade the debt and equity securities or financial instruments (including derivatives, bank loans or other obligations) of Ortho, Carlyle or Quidel for their own accounts or for the accounts of customers and, accordingly, may at any time hold long or short positions in such securities or other financial instruments. During the two year period preceding the date of J.P. Morgan’s opinion, the aggregate fees recognized by J.P. Morgan from each of Ortho, Carlyle and its controlled portfolio companies, and Quidel were approximately $21 million, $278 million, and $0.2 million, respectively.

Unaudited Forward-Looking Financial Information

Quidel Unaudited Forward-Looking Financial Information

Quidel does not as a matter of course publicly disclose projections as to future sales, earnings, or other results due to the inherent unpredictability and subjectivity of the underlying assumptions and estimates. However, in connection with the discussions regarding the Combinations, each of Quidel and Ortho supplied the other with certain unaudited business and financial information that was not publicly available. Quidel provided its board of directors, Perella Weinberg, and Ortho with certain financial projections that were prepared by and are the responsibility of the management of Quidel, and which are referred to in this section as the “Quidel Management Projections.” The Quidel Management Projections include projections for Quidel prepared by Quidel management (which Quidel refers to as the “Quidel Management Projections for Quidel”) and projections for Ortho prepared by Quidel management (which Quidel refers to as the “Quidel Management Projections for Ortho”). The Quidel Management Projections treat each of Quidel and Ortho on a stand-alone basis, without giving effect to, and as if Quidel and Ortho never contemplated, the Combinations, including the impact of negotiating or executing the BCA, the expenses that may be incurred in connection with consummating the Combinations, the potential synergies that may be achieved by the combined company as a result of the Combinations, the effect of any business or strategic decision or action that has been or will be taken as a result of the BCA having been executed, or the effect of any business or strategic decisions or actions which would likely have been taken if the BCA had not been executed but which were instead altered, accelerated, postponed or not taken in anticipation of the Combinations.

The Quidel Management Projections were not prepared with a view toward public disclosure and, accordingly, do not necessarily comply with published guidelines of the SEC, the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts or GAAP, but, in the view of Quidel’s management, were prepared on a reasonable basis, reflected the best available estimates and judgments at the time of preparation and presented as of the time of preparation, to the best of Quidel’s management’s knowledge and belief, the reasonable projections of the future financial performance of Quidel and Ortho, respectively. Neither Quidel’s independent registered public accounting firm, nor any other independent accountants, have audited, reviewed, compiled or performed any procedures with respect to the Quidel Management Projections or expressed any opinion or any form of assurance related thereto. The summary of the projections is included in this joint proxy statement/prospectus solely to give you access to certain financial projections that were made available to the Quidel board of directors, Perella Weinberg and Ortho, and is not being included in this joint proxy statement/prospectus to influence a stockholder’s decision whether to vote for the Merger Proposal or any other proposal.

263

The Quidel Management Projections, while presented with numerical specificity, necessarily were based on numerous variables and assumptions (described in greater detail below) are inherently uncertain and many of which are beyond the control of Quidel’s management. Because the projections cover multiple years, by their nature, they also become subject to greater uncertainty with each successive year. The Quidel Management Projections constitute forward-looking information and are subject to risks and uncertainties that could cause actual results to differ materially from the results forecasted, including risks and uncertainties relating to Quidel’s and Ortho’s businesses (including their ability to achieve strategic goals, objectives and targets over applicable periods), industry performance, the COVID-19 pandemic, general business and economic conditions, the Combinations (including risks that the Combinations are not consummated for any reason or that the Combinations fail to generate the anticipated benefits and synergies), the business of the combined company, and other factors described in this joint proxy statement/prospectus. Please consider carefully the sections of this joint proxy statement/prospectus entitled “Cautionary Statement Concerning Forward-Looking Statements” and “Risk Factors.” Accordingly, there can be no assurance that the Quidel Management Projections will be realized.

The inclusion of the projections in this joint proxy statement/prospectus should not be regarded as an indication that Quidel, Ortho or any of their respective affiliates, advisors (including Perella Weinberg and J.P. Morgan), officers, directors or representatives considered or considers the Quidel Management Projections to be necessarily predictive of actual future events, and that the Quidel Management Projections should not be relied upon as such. Quidel does not intend to make publicly available any update or other revision to the Quidel Management Projections, except as otherwise required by law.

Certain of the projected financial information set forth herein may be considered non-GAAP financial measures. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with GAAP, and non-GAAP financial measures as used by Quidel may not be comparable to similarly titled amounts used by other companies. Financial measures provided to a board of directors or financial advisor in connection with a business combination are excluded from the definition of non-GAAP financial measures under the rules of the SEC, and therefore the Quidel Management Projections are not subject to SEC rules regarding disclosures of non-GAAP financial measures, which would otherwise require a reconciliation of a non-GAAP financial measure to a GAAP financial measure. No reconciliation of non-GAAP financial measures in the Quidel Management Projections to GAAP measures was created or used in connection with preparing the Quidel Management Projections. Accordingly, no reconciliation of the financial measures included in the Quidel Management Projections is provided in this joint proxy statement/prospectus.

In light of the foregoing factors and the uncertainties inherent in the Quidel Management Projections, Quidel stockholders are cautioned not to place undue reliance on the Quidel Management Projections.

Quidel Management Projections for Quidel

The following table sets forth a summary of the Quidel Management Projections for Quidel. In connection with the evaluation of the Combinations, Quidel’s management prepared projections of Quidel’s financial results for calendar years 2021 through 2026. Two sets of financial projections, which are referred to in this section as the Case 1 projections (the LRP projections) and the Case 2 projections (the adjusted LRP projections), respectively, were prepared by Quidel’s management in order to give the Quidel board of directors insight into possible alternative outcomes.

For the Case 1 projections, Quidel’s management utilized Quidel’s long range plan projections (the “Quidel LRP”) initially developed in August 2021. Some of the key assumptions Quidel management made in preparing the Quidel LRP were: continued growth in sales of Quidel’s Sofia and QuickVue products after the COVID-19 pandemic ends; continued market demand for Quidel’s COVID-19 tests after the prevalence of the delta and omicron variants has decreased; and future success of its new product launches, specifically its Savanna instrumented system and assays and a U.S. launch of its high-sensitive troponin assay that would run on its MeterPro instrument. Also, Quidel’s management assumed that at-home testing and OTC testing will continue to grow due to the market movement toward more decentralized testing, which trend should favor both Quidel’s Sofia 2 and SofiaQ platforms, as well as its QuickVue product lines. Quidel’s management believes that its current products, and its new products that are expected to be launched over the next several years, will realize revenue growth due to the following product attributes of these products: ease of use, fast turn time, and cost effectiveness.

The key difference between Case 1 and Case 2 is that the Case 1 projections represent Quidel management’s view of Quidel’s projected financial results assuming a favorable outcome on a number of key assumptions, while the Case 2 projections were risk adjusted for years 2023 and beyond to take into account a view that the following risks could result in less favorable results than those assumed in preparation of the Case 1 projects: the risks associated with estimating the

264

duration of the COVID-19 pandemic and its impact, the risks associated with Quidel’s development and commercialization of new technologies, products and markets, and the difficulty of estimating the timing, nature and magnitude of future opportunities for Quidel’s at-home testing products and services. The Case 2 projections reflected what Quidel’s management and the Quidel board of directors believed to be a more conservative view of Quidel’s projected financial results for such years.

The Case 1 projections were made available to Ortho in connection with its due diligence review of Quidel, but the Case 2 projections were not made available to Ortho prior to signing of the BCA.

The Quidel board of directors instructed Perella Weinberg to use both the Case 1 and Case 2 Quidel Management Projections for Quidel for purposes of performing its financial analyses summarized under “The Combinations—Opinion of Perella Weinberg Partners LP as Financial Advisor to Quidel” in this joint proxy statement/prospectus.

(2) | Unlevered Free Cash Flow is calculated as EBITDA less taxes and capital expenditures, and adjusted for changes in net working capital.

Quidel Management Projections for Ortho

The following table sets forth a summary of the Quidel Management Projections for Ortho. The Quidel Management Projections for Ortho were prepared by Quidel management, after review of the Ortho Management Projections for Ortho made available to Quidel in connection with its due diligence review of Ortho and the Combinations and reflect the results of Quidel’s due diligence review and various assumptions and estimates as to future events made by Quidel management. These projections were used by the Quidel board of directors in connection with the evaluation of the Combinations and were made available to Perella Weinberg for purposes of performing its financial analyses summarized under “The Combinations—Opinion of Perella Weinberg Partners LP as Financial Advisor to Quidel” in this joint proxy statement/prospectus. Some of the key assumptions Quidel management made in preparing the Quidel Management Projections for Ortho were a differing view than that adopted by Ortho management regarding non-GAAP add-backs in calculating EBITDA.

(1) | EBITDA is a non-GAAP financial measure which is calculated as earnings before interest expense, net provision for (benefit from) income taxes, depreciation and amortization and should not be considered as an alternative to net income as a measure of operating performance. Quidel’s projections do not eliminate (i) certain non-operating income or expense, and (ii) impacts of certain noncash, unusual or other items that are included in net income (loss) that Ortho does not consider indicative of its ongoing operating performance, including but not limited to stock based compensation expense on historical equity awards.

(2) | Unlevered Free Cash Flow is calculated as EBITDA less taxes and capital expenditures, and adjusted for changes in net working capital.

Ortho Unaudited Forward-Looking Financial Information

Ortho does not as a matter of course publicly disclose long-term financial projections due to, among other reasons, the uncertainty, unpredictability and subjectivity of the underlying assumptions and estimates. As a result, Ortho does not endorse unaudited forward-looking financial information as a reliable prediction of future results. The limited unaudited forward-looking financial information set out below is included in this joint proxy statement/prospectus solely because it was among the financial information made available to the Ortho board of directors and its financial advisors in connection with their respective evaluations of the Combinations.

The unaudited forward-looking financial information presented below includes projections for Ortho prepared by Ortho management (the “Ortho Management Projections for Ortho”) and projections for Quidel prepared by Ortho management (the “Ortho Management Projections for Quidel”). Ortho refers to both the Ortho Management Projections for Ortho and the Ortho Management Projections for Quidel as the “Ortho Management Projections.” The Ortho Management Projections were based on estimates and assumptions made by management at the respective times of their preparation and speak only as of such times, as applicable. Except to the extent required by applicable law, Ortho has no intention to update or revise the forward-looking financial information included in this joint proxy statement/prospectus and, except as provided below, has not done so and does not intend to do so.

The inclusion of this unaudited forward-looking financial information should not be regarded as an indication that any of Ortho, Quidel, J.P. Morgan, Perella Weinberg or any of their respective affiliates, officers, directors, partners, advisors or other representatives considered, or now considers, it to be an accurate prediction of actual future results, and readers of this joint proxy statement/prospectus are cautioned not to rely on this forward-looking information. There can be no assurance that the forward-looking results will be achieved or that actual results will not be significantly higher or lower than estimated.

Since the Ortho Management Projections cover multiple years, such information by its nature becomes less accurate with each successive year. Quidel stockholders and Ortho shareholders are urged to review the risk factors described in the section entitled “Risk Factors—Risks Relating to Ortho’s Business” of this joint proxy statement/prospectus with respect to the business of Ortho. Quidel stockholders and Ortho shareholders are also urged to review the risks and other factors described in the sections entitled “Risk Factors” and “Cautionary Statement Concerning Forward-Looking Statements” of this joint proxy statement/prospectus with respect to the business of Quidel. The Ortho Management Projections were not prepared with a view toward public disclosure, nor were they prepared with a view toward compliance with published guidelines of the SEC, the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of forward-looking financial information or U.S. GAAP. The Ortho Management Projections included in this proxy statement/prospectus have been prepared by, and is the responsibility of, Ortho management. PricewaterhouseCoopers LLP and Ernst & Young LLP have not audited, reviewed, examined, compiled nor applied agreed-upon procedures with respect to the accompanying Ortho Management Projections and, accordingly, PricewaterhouseCoopers LLP and Ernst & Young LLP do not express an opinion or any other form of assurance with respect thereto. The PricewaterhouseCoopers LLP report included in this document relates to Ortho’s previously issued financial statements. It does not extend to the Ortho Management Projections and should not be read to do so. The Ortho Management Projections include certain financial measures that are not consistent with U.S. GAAP. Adjusted EBITDA and Unlevered Free Cash Flow are non-U.S. GAAP financial measures that are not consistent with U.S. GAAP and should not be considered in isolation from, or as a substitute for, financial information presented in compliance with U.S. GAAP. Financial measures that are not consistent with U.S. GAAP as used by Ortho may not be comparable to similarly titled amounts used by other companies. The footnotes to the table below provide certain supplemental information with respect to the calculation of these financial measures that are not consistent with U.S. GAAP. Furthermore, the Ortho Management Projections do not take into account any circumstances or events occurring after the date they were prepared and do not give effect to the Combinations.

Ortho Management Projections for Ortho

The following table sets forth a summary of the Ortho Management Projections for Ortho. The Ortho Management Projections for Ortho were prepared according to Ortho internal management financial reporting framework. These projections were used by the Ortho board of directors in connection with the evaluation of the Combinations and were made available to J.P. Morgan for purposes of performing its financial analyses summarized under “Opinion of J.P. Morgan Securities LLC as Financial Advisor to Ortho” in this joint proxy statement/prospectus. In addition, these projections were made available to Quidel in connection with its due diligence review of Ortho and the Combinations.

|  | Ortho Management Projections for Ortho |
(In millions of dollars) |  | 2021E |  |  | 2022E |  |  | 2023E |  |  | 2024E |  |  | 2025E |  |  | 2026E |  |  | Terminal |
Total Revenue |  | $ | 2,030 |  |  | $ | 2,149 |  |  | $ | 2,275 |  |  | $ | 2,432 |  |  | $ | 2,598 |  |  | $ | 2,796 |  |  | $ | 2,866 |
Core Revenue(1) |  |  | 2,012 |  |  |  | 2,128 |  |  |  | 2,266 |  |  |  | 2,423 |  |  |  | 2,589 |  |  |  | 2,788 |  |  |  |  |
Adjusted EBITDA (excluding Ortho Synergies Estimates)(2) |  |  | 537 |  |  |  | 582 |  |  |  | 622 |  |  |  | 672 |  |  |  | 727 |  |  |  | 799 |  |  |  | 819 |
Unlevered Free Cash Flow(3) |  |  | 313 |  |  |  | 283 |  |  |  | 336 |  |  |  | 381 |  |  |  | 423 |  |  |  | 474 |  |  |  | 469 |

(1) | Core Revenue is defined as revenue from Ortho’s Clinical Laboratories and Transfusion Medicine businesses and does not include “other product revenue” (primarily revenue from contract manufacturing) or revenue from collaboration and license agreements.

(2) | Adjusted EBITDA is a non-GAAP financial measure which is calculated as earnings before interest expense, net provision for (benefit from) income taxes, depreciation & amortization and eliminates (i) certain non-operating income or expense and (ii) impacts of certain noncash, unusual or other items that are included in net income (loss) that we do not consider indicative of our ongoing operating performance, including but not limited to stock based compensation expense on historical equity awards granted under Ortho’s 2014 Equity Incentive Plan prior to Ortho’s IPO. Ortho’s projections include stock based compensation expense on equity awards granted after the Ortho IPO under Ortho’s 2021 Incentive Award Plan and any future equity incentive plans adopted by Ortho. Adjusted EBITDA should not be considered as an alternative to net income as a measure of operating performance.

(3) | Unlevered Free Cash Flow was calculated by J.P. Morgan, for purposes of its discounted cash flow analysis and based on estimates provided by Ortho management, as future cash flows generated by an asset without including in such calculation any debt servicing costs. Specifically, unlevered free cash flow for this purpose represents Adjusted EBITDA less taxes, capital expenditures, increases in net working capital, stock-based compensation and reagent rental instruments. For purposes of its discounted cash flow analyses and based on estimates provided by Ortho management, Perella Weinberg calculated Unlevered Free Cash Flow of Ortho for this purpose as EBITDA less taxes, plus depreciation and amortization, and less capital expenditures and increases in net working capital, resulting in Unlevered Free Cash Flow of approximately $313 million, $284 million, $337 million, $382 million, $425 million, $476 million and $523 million for 2021E, 2022E, 2023E, 2024E, 2025E, 2026E and the terminal year, respectively.

Although presented with numerical specificity, the Ortho Management Projections for Ortho reflect numerous assumptions and estimates as to future events made by Ortho management. At the time the Ortho Management Projections were prepared, Ortho management believed such assumptions and estimates were reasonable. In preparing the Ortho Management Projections, Ortho management made assumptions regarding, among other things, IVD market growth and the impact of COVID-19 in future years, sales of our COVID-19 assays, successful execution on our new product portfolio and commercial excellence initiative, and movement of foreign currency. Ortho assumes that the IVD market will revert to its historical trajectory as the COVID-19 impact dissipates in fiscal year 2022. Ortho also anticipates that sales of our COVID-19 assays peaked in fiscal year 2021 and will substantially decline in fiscal year 2022 onwards. Foreign currency rates were projected based on rates at the time the projections were prepared. As of December 31, 2021, foreign currency has become a headwind as the U.S. dollar strengthened against Ortho’s key currencies.

The Ortho Management Projections for Ortho do not reflect various risks to achieving these projections. These risks include, but are not limited to, changes in market growth or other factors that could impact our expected growth; accelerated decline of Ortho’s COVID-19 assays; foreign currency changes; continued supply chain constraints and increasing costs resulting from such constraints; and the timely launch and successful execution of new Ortho products.

In connection with commercial diligence, Ortho management provided to Quidel its initial estimates of the ability to utilize Ortho’s net operating losses over the projection period, which amounts were calculated as a tax benefit equal to $49 million in 2022, $53 million in 2023, $61 million in 2024, less than $1 million in 2025, and $0 thereafter. Perella Weinberg utilized

267

these initial estimates for purposes of its financial analyses. After further internal review, Ortho management updated its estimates for purposes of the Ortho Management Projections for Ortho, calculating such tax benefit as the amount equal to, $16 million in 2022, $36 million in 2023, $50 million in 2024, $56 million in 2025 and $29 million in 2026. The updated estimates of tax benefits, which were not provided to Quidel or Perella Weinberg, were utilized by J.P. Morgan for purposes of its financial analyses.

Ortho Management Projections for Quidel

The following table sets forth a summary of the Ortho Management Projections for Quidel. The Ortho Management Projections for Quidel were prepared by Ortho management, after review of the Quidel Management Projections for Quidel—LRP Projections (Case 1) made available to Ortho in connection with its due diligence review of Quidel and the Combinations and reflect the results of Ortho’s due diligence review and various assumptions and estimates as to future events made by Ortho management. The Quidel Management Projections for Quidel—Adjusted LRP Projections (Case 2) was not made available to Ortho prior to signing of the BCA. These projections were used by the Ortho board of directors in connection with the evaluation of the Combinations and were made available to J.P. Morgan for purposes of performing its financial analyses summarized under “Opinion of J.P. Morgan Securities LLC as Financial Advisor to Ortho” in this joint proxy statement/prospectus.

|  | Ortho Management Projections |
(In millions of dollars) |  | 2021E |  |  | 2022E |  |  | 2023E |  |  | 2024E |  |  | 2025E |  |  | 2026E |  |  | Terminal |
Total Net Revenue |  | $ | 1,574 |  |  | $ | 1,165 |  |  | $ | 998 |  |  | $ | 1,172 |  |  | $ | 1,430 |  |  | $ | 1,745 |  |  | $ | 1,789 |
Adjusted EBITDA (post-stock based compensation and excluding synergies)1 |  |  | 856 |  |  |  | 525 |  |  |  | 348 |  |  |  | 474 |  |  |  | 623 |  |  |  | 757 |  |  |  | 776 |
Unlevered Free Cash Flow2 |  | $ | 455 |  |  | $ | 379 |  |  | $ | 160 |  |  | $ | 279 |  |  | $ | 387 |  |  | $ | 467 |  |  | $ | 506 |

(1) | Adjusted EBITDA is a non-GAAP financial measure which is calculated as earnings before interest expense, net provision for (benefit from) income taxes, depreciation & amortization and eliminates (i) certain non-operating income or expense and (ii) impacts of certain noncash, unusual or other items that are included in net income (loss) that we do not consider indicative of our ongoing operating performance.

(2) | Unlevered Free Cash Flow was calculated by J.P. Morgan, for purposes of its discounted cash flow analysis and based on estimates provided by Ortho management, as future cash flows generated by an asset without including in such calculation any debt servicing costs. Specifically, unlevered free cash flow for this purpose represents adjusted EBITDA less taxes, capital expenditures, increases in net working capital, stock-based compensation and reagent rental instruments.

Although presented with numerical specificity, the Ortho Management Projections for Quidel reflect various assumptions and estimates as to future events made by Ortho management. At the time the Ortho Management Projections for Quidel were prepared, Ortho management believed such assumptions and estimates were reasonable. In preparing the Ortho Management Projections for Quidel, Ortho management made assumptions regarding, among other things, the market demand for COVID-19 testing, growth in Non-COVID PoC testing (Sofia and QuickVue) and successful execution on Quidel’s new product portfolio (Savanna launch). Ortho anticipates that there will be continued testing demand for COVID-19 as the disease transitions from a pandemic towards an endemic state, where it will be additive to other seasonal respiratory disease testing such as, but not limited to, Flu A/B and RSV. Ortho anticipates that at-home and OTC testing will remain a critical part of combating COVID-19 as additional variants emerge, and will shift over time to multiplex panel-based testing where Quidel is well-positioned with both antigen and molecular respiratory panels on the Sofia2 and Savanna platforms. Based on market and customer research, Ortho believes that the launch of the Savanna multiplex molecular platform will provide significant opportunity due to ease of use, rapid time to result, and relative cost position, and that the platform will be competitive across various molecular segments in both hospital and clinic-based settings, and across various geographies around the world.

The Ortho Management Projections for Quidel do not reflect various risks to achieving these projections. These risks include, but are not limited to, COVID-19 testing declining more rapidly than anticipated, increased competition which erodes pricing for COVID-19 tests and multiplex panels, regulatory timing and other regulatory issues with the Savanna platform and test panels, regulatory timing and other regulatory issues with the high-sensitivity troponin assay, supply chain constraints inhibiting procurement of key components, and the inability of Quidel to capture market share in the white-label rapid antigen testing market.

Unaudited Pro Forma Synergy Estimates for Topco

In connection with the discussions regarding the Combinations, Quidel and Ortho jointly prepared estimates of the cost and revenue synergies expected to be realized by Topco following completion of the Combinations. These jointly prepared estimates included estimated cost synergies to be achieved by year 3 and revenue synergies for years 2022 through 2025 (the “Joint Synergies Estimates”). Each of Ortho and Quidel separately prepared an estimate of the revenue synergies for 2026.

While such potential cost and revenue synergies were collaboratively developed by Quidel management and Ortho management, each of Quidel and Ortho separately established its own assumptions relating to the timing of the cost and revenue synergies, any annual inflation adjustment to baseline costs and the expected cost to achieve these synergies.

This unaudited prospective financial information represents Ortho management’s and Quidel management’s joint estimates and assumptions regarding the potential cost synergies realizable in Topco through operational efficiencies, supply chain optimization and shared administrative functions, and revenue synergies realizable through Quidel’s expansive point-of-care diagnostics portfolio with access to Ortho’s broad global reach.

Quidel: Using the Joint Synergies Estimates and Quidel management’s estimate of the revenue synergies for 2026, Quidel management prepared estimates of the net cost synergies on a pre-tax and post-tax basis and estimates of the revenue synergies contribution to pre-tax and post-tax earnings (collectively, the “Quidel Synergies Estimates”). In preparing the Quidel Synergies Estimates, Quidel management used as the foundation for these estimates the unaudited forward-looking financial information presented to the Quidel board of directors on December 22, 2021 (referenced above in the section entitled “Quidel Unaudited Forward-Looking Financial Information” of this joint proxy statement/prospectus. Quidel management reviewed the Quidel Synergies Estimates with the Quidel board of directors on December 22, 2021. The Quidel Synergies Estimates were also provided to Perella Weinberg and, at the direction of the management of Quidel, were utilized by Perella Weinberg for purposes of its financial analyses as described above in the section entitled “Opinion of Perella Weinberg Partners LP as Financial Advisor to Quidel”. The following table sets forth a summary of the Quidel Synergies Estimates.

(1) | EBIT is a non-GAAP financial measure which is calculated as earnings before interest expense, net and provision for (benefit from) income taxes.

Ortho: Using the Joint Synergies Estimates and Ortho management’s estimate of the revenue synergies for 2026, Ortho management prepared estimates of the net cost synergies on a pre-tax and post-tax basis and estimates of the revenue synergies contribution to pre-tax and post-tax earnings (collectively, the “Ortho Synergies Estimates”). Ortho management reviewed the Ortho Synergies Estimates with the Ortho board of directors on December 22, 2021. The Ortho Synergies Estimates, which were not provided to Quidel or Perella Weinberg, were also provided to J.P. Morgan and, at the direction of the management of Ortho, were utilized by J.P. Morgan for purposes of its financial analyses as described above under the section entitled “Opinion of J.P. Morgan Securities LLC as Financial Advisor to Ortho”.

Important factors that may affect actual results and result in the Quidel Synergies Estimates or the Ortho Synergies Estimates not being achieved include, but are not limited to: the failure to integrate successfully the businesses of Quidel and Ortho in the expected timeframe; the failure of Topco to effectively manage its expanded operations following the Combinations; risks relating to Ortho’s indebtedness; the failure to realize the targeted cost synergies expected from the Combinations; and foreign currency exchange risk.

No assurances can be given that the assumptions made in preparing the Ortho Management Projections, the Quidel Management Projections, the Quidel Synergies Estimates or the Ortho Synergies Estimates will accurately reflect future conditions. The estimates and assumptions underlying the unaudited forward-looking financial information involve judgments with respect to, among other things, future economic, competitive, regulatory and financial market conditions and future business decisions which may not be realized and that are inherently subject to significant business, economic, competitive and regulatory uncertainties and contingencies, including, among others, risks and uncertainties described under the sections entitled “Risk Factors” and “Cautionary Statement Concerning Forward-Looking Statements” of this joint proxy statement/prospectus, all of which are difficult to predict and many of which are beyond the control of Ortho and/or Quidel and will be beyond the control of the combined company. There can be no assurance that the underlying assumptions will prove to be accurate or that the projected results will be realized, and actual results likely will differ, and may differ materially, from those reflected in the unaudited forward-looking financial information, whether or not the Combinations are completed.

Neither Quidel nor Ortho or any of their respective affiliates, advisors (including J.P. Morgan and Perella Weinberg), officers, directors or representatives has made or makes any representation to any Quidel stockholder, any Ortho shareholder or any other person regarding the ultimate performance of Quidel or Ortho compared to the information contained in the foregoing unaudited forward-looking financial information or can give any assurance that actual results will not differ materially from such unaudited forward-looking financial information, and none of them undertakes any obligation to update or otherwise revise or reconcile such unaudited forward-looking financial information to reflect circumstances existing after the date that such unaudited forward-looking financial information was generated or to reflect the occurrence of future events even in the event that any or all of the assumptions underlying such unaudited forward-looking financial information are shown to be in error.

The unaudited forward-looking financial information referred to as the Ortho Management Projections above was prepared by Ortho management and was not approved by Quidel or any affiliate or employee thereof. The unaudited forward-looking financial information referred to as the Quidel Management Projections above was prepared by Quidel management and was not approved by Ortho or any affiliate or employee thereof.

ORTHO AND QUIDEL HAVE NOT UPDATED OR OTHERWISE REVISED AND DO NOT INTEND TO UPDATE OR OTHERWISE REVISE FOR THE PURPOSE OF THIS JOINT PROXY STATEMENT/PROSPECTUS THE ORTHO MANAGEMENT PROJECTIONS, THE QUIDEL MANAGEMENT PROJECTIONS, THE QUIDEL SYNERGIES

270

ESTIMATES OR THE ORTHO SYNERGIES ESTIMATES TO REFLECT CIRCUMSTANCES EXISTING AFTER THE DATE PREPARED OR TO REFLECT THE OCCURRENCE OF FUTURE EVENTS, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING SUCH FORWARD-LOOKING FINANCIAL INFORMATION ARE NO LONGER APPROPRIATE, EXCEPT AS MAY BE REQUIRED BY LAW.

Closing Date and Effective Times

Pursuant to the terms of the BCA, Ortho and Topco will each use their respective reasonable best efforts to obtain an order of the High Court of Justice of England and Wales under Part 26 of the UK Companies Act sanctioning the Ortho Scheme (the “Ortho Scheme Order”), which shall be effective once the Ortho Scheme Order is duly filed with the Registrar of Companies in England and Wales (the “Registrar”).

The closing of the Combinations will take place on the Closing Date the Ortho Scheme Order is duly filed with the Registrar (the “Scheme Effective Date”). Subject to the terms and conditions set forth in the BCA, on the Closing Date, and as soon as practicable after the Ortho Scheme Order is duly filed with the Registrar, Quidel will file the Quidel Certificate of Merger with the Secretary of State of the State of Delaware in accordance with the relevant provisions of the DGCL and shall make all other filings or recordings required under the DGCL.

The Combinations will become effective sequentially (i) with the Ortho Scheme Order becoming effective on the Scheme Effective Date and at the time the Ortho Scheme Order is duly delivered to the Registrar, such time being the “Ortho Effective Time” and (ii) with the Quidel Certificate of Merger providing that the Quidel Merger shall become effective on the Scheme Effective Date immediately following the Ortho Effective Time (or such subsequent time as Ortho and Quidel shall agree and as shall be specified in the Quidel Certificate of Merger, and in no event prior to the Ortho Effective Time), such time being the “Quidel Effective Time.”

Subject to the satisfaction or waiver of the conditions to the closing described in the section entitled “The Business Combination Agreement—Conditions to the Combinations” of this joint proxy statement/prospectus, including the approval of the Ortho Scheme by Ortho shareholders at the Ortho Court Meeting and adoption of the BCA by the Quidel stockholders at the Quidel Stockholders’ Meeting, the sanction hearing of Ortho having taken place and the filing of the Ortho Scheme Order with the Registrar, it is anticipated that the Combinations will close in the first half of 2022. However, neither Ortho nor Quidel can predict the actual date on which the Combinations will be completed, or if the Combinations will occur at all, because completion of the Combinations is subject to conditions and factors outside the control of both companies. It is possible that factors outside the control of both companies could result in the Combinations being completed at a different time, or not at all.

Board of Directors and Management of Topco Following Completion of the Combinations

Board of Directors

Effective as of the Ortho Effective Time, the Topco board of directors will consist of 12 members and be composed as follows: (i) eight directors designated by Quidel prior to closing, expected to consist of Messrs. Bryant, Buechler, Michael, Strobeck, Widder and Wilkins and Mses. Polan and Rhoads, each of whom, other than Mr. Bryant, qualifies as an “independent director” under applicable rules of Nasdaq, and (ii) four directors designated by Ortho prior to closing, at least two of whom will qualify as an “independent director” under the applicable rules of Nasdaq. Each of the members of the Topco board of directors designated by Ortho shall be reasonably acceptable to the nominating and corporate governance committee of the current Quidel board of directors. In connection with the BCA, Ortho and the Carlyle Stockholder executed a letter agreement pursuant to which Ortho agrees that, at the closing, the Ortho designees to the Topco board of directors will include two Carlyle nominees.

In addition, pursuant to the terms of the BCA, Douglas Bryant, current President and Chief Executive Officer of Quidel, will serve as the Chair of the Topco board of directors at the Ortho Effective Time. The Topco board of directors intends to appoint a lead independent director, since Mr. Bryant will serve as the Chief Executive Officer of Topco and Chair of the Topco board of directors.

Douglas C. Bryant, age 64, will serve as Chief Executive Officer of Topco and Chair of the Topco board of directors. Mr. Bryant is currently President and Chief Executive Officer of Quidel and a member of the Quidel board of directors. Prior to joining Quidel in 2009, Mr. Bryant served as Executive Vice President and Chief Operating Officer at Luminex

271

Corporation, managing its Bioscience Group, Luminex Molecular Diagnostics (Toronto), manufacturing, R&D, technical operations and commercial operations. From 1983 to 2007, Mr. Bryant held various worldwide commercial operations positions with Abbott Laboratories, including, among others: Vice President of Abbott Vascular for Asia/Japan, Vice President of Abbott Molecular Global Commercial Operations and Vice President of Abbott Diagnostics Global Commercial Operations. Earlier in his career with Abbott, Mr. Bryant was Vice President of Diagnostic Operations in Europe, the Middle East and Africa and Vice President of Diagnostic Operations in Asia Pacific. Mr. Bryant has over 30 years of industry experience in sales and marketing, product development, manufacturing and service and support in both the diagnostics and life sciences markets. Mr. Bryant holds a B.A. in Economics from the University of California at Davis.

Committees of the Topco Board of Directors

As of the Ortho Effective Time, the Topco board of directors will form the following board committees: the Audit Committee, the Compensation Committee and the Nominating and Governance Committee. The Audit Committee, the Compensation Committee and the Nominating and Governance Committee will each be chaired by a member of the Topco board of directors designated by Quidel. The Audit Committee, the Compensation Committee and the Nominating and Governance Committee will each consist of one member of the Topco board of directors designated by Ortho and not less than two additional members of the Topco board of directors designated by Quidel, in each case, subject to applicable legal and regulatory requirements, and, in the case of the Ortho designees, such designees must be reasonably acceptable to the Topco board of directors. The charters for the Audit Committee, the Compensation Committee and the Nominating and Governance Committee will each be substantially similar to the charters for the respective committees of the Quidel board of directors that were in effect as of the date of the BCA.

Management

Pursuant to the terms of the BCA, at the Ortho Effective Time, Douglas Bryant, current President and Chief Executive Officer of Quidel, will serve as Chair and Chief Executive Officer of Topco.

In addition, at the Ortho Effective Time, the following individuals will serve as officers of Topco:

Joseph M. Busky, age 54, will serve as Chief Financial Officer. Mr. Busky is currently Chief Financial Officer of Ortho. Prior to joining Ortho in 2020, Mr. Busky served as chief financial officer for global medical device company, Vyaire Medical, Inc., from 2018 through 2020, as chief executive officer of Qualtek from 2017 to 2018, and as chief financial officer of FDH Velocitel from 2015 to 2017. He has also previously held leadership roles at InnerWorkings, Inc. and Siemens Medical Solutions Diagnostics/Dade Behring Holdings, Inc. Mr. Busky holds an MBA with a finance concentration, as well as a BBA in accounting, from Loyola University in Baltimore. He also holds a CPA certification in Maryland from the American Institute of Certified Public Accountants.

Robert J. Bujarski, age 53, will serve as President and Chief Operating Officer. Mr. Bujarski is currently Chief Operating Officer of Quidel, a position he has held since 2020.

Accounting Treatment

Topco will account for the Combinations using the acquisition method of accounting in accordance with ASC Topic 805. For further information, see the section entitled “Unaudited Pro Forma Combined Financial Information” of this joint proxy statement/prospectus.

Regulatory Matters

Ortho and Quidel have agreed to use their reasonable best efforts to obtain all regulatory approvals required to complete the transactions contemplated by the BCA. These approvals include clearance under the HSR Act, and other merger control and foreign investment laws and regulations. Ortho and Quidel have completed, or will complete, the filing of applications and notifications to obtain the required regulatory approvals.

Antitrust and Merger Control

United States. Under the HSR Act, and the rules and regulations promulgated thereunder, the Combinations may not be completed until notification and report forms have been filed with the FTC and the Antitrust Division of the U.S. Department of Justice (the “Antitrust Division”) and all applicable waiting periods have expired or been terminated. Ortho and Quidel each filed an HSR notification with the FTC and the Antitrust Division on January 10, 2022. The waiting period under the HSR Act with respect to the filed notifications expired at 11:59 p.m., Eastern Time, on February 9, 2022. Ortho and Quidel continue to expect the Combinations to close in the first half of 2022.

United Kingdom. Under the Enterprise Act 2002 and the rules and regulations promulgated thereunder, the merger control regime in the UK is voluntary and in any event the merger control thresholds are not met. The parties do not intend to make a voluntary filing unless the UK CMA opens or indicates that it intends to open an own-initiative investigation prior to closing of the Combinations.

Foreign Jurisdictions. Ortho and Quidel have ensured the filing of notifications, notices or applications pursuant to antitrust and competition laws in Russia and Turkey and foreign investment laws in France, Italy and Spain. Clearance decisions have been granted in Russia and Italy as of March 1, 2022. The parties must observe mandatory waiting periods and/or obtain the necessary waivers, consents, clearances, approvals or authorizations pursuant to these remaining foreign antitrust, competition and foreign investment laws before completing the Combinations. The parties will also file a notification under foreign investment laws in Canada after closing of the Combinations.

At any time before or after completion of the Combinations, the Antitrust Division, the FTC, state attorneys general, or foreign antitrust, competition and foreign investment authorities could take any action under U.S. federal or state antitrust laws, or foreign laws, as they deem necessary or desirable in the public interest, including seeking to enjoin the Combinations, or seeking the divestiture of substantial assets or other divestiture, behavioral or conduct remedies, conditions or commitments. Private parties may also bring legal actions under U.S. federal, state or foreign antitrust, competition and foreign investment laws under certain circumstances. There can be no assurance that a challenge to the Combinations on antitrust, competition and foreign investment grounds will not be made or, if a challenge is made, of the result of the challenge.

Commitment to Obtain Approvals

Ortho and Quidel have agreed to cooperate with each other and use reasonable best efforts to take all actions and do all things necessary, proper or advisable to consummate the Combinations as soon as practicable. These reasonable best efforts include an obligation to obtain as promptly as practicable all regulatory approvals and consents necessary or advisable in order to consummate the Combinations.

No Assurance of Approvals

As of the date of this joint proxy statement/prospectus, Ortho and Quidel have completed, or will complete, the filing of applications and notifications to obtain the required regulatory approvals. The parties believe that the Combinations can be completed in compliance with all applicable regulatory laws. However, there can be no assurance that the antitrust, competition or foreign investment authorities will terminate or permit the applicable waiting periods to expire, or approve or

273

clear the Combinations at all, or that they will do so without restrictions, required commitments or conditions. There also can be no assurance that a challenge to completion of the Combinations under the antitrust, competition or foreign investment laws will not be made or that, if such a challenge were made, the parties would prevail or would not be required to accept certain conditions, possibly including divestitures and behavioral and conduct restrictions, conditions or commitments, in order to complete the Combinations.

We cannot assure you that all of the regulatory approvals described above will be obtained, and, if obtained, we cannot assure you as to the date of any approvals or the absence of any litigation or remedies, conditions or commitments related to such approvals.

Ortho and Quidel are not aware of any material governmental approvals or actions that are required for completion of the Combinations other than those described above. It is presently contemplated that if any such additional governmental approvals or actions are required, those approvals or actions will be sought. There can be no assurance, however, that any additional approvals or actions will be obtained.

The Parties’ Intentions Regarding Ortho and Quidel

Quidel and Ortho have commenced, and following the Closing Date, Topco will continue, a comprehensive evaluation of Topco’s operations and will identify the best way to integrate the organizations in order to further improve Topco’s ability to serve its customers, as well as achieve revenue and cost synergies. Employees from both Ortho and Quidel are and will be involved in the evaluation, formation and execution of the integration plans.

Until these evaluations and formation of plans have been completed, Ortho and Quidel are not in a position to comment on prospective potential impacts upon employment, specific locations or any redeployment of fixed assets.

U.S. Federal Securities Law Consequences

Subject to the effectiveness of the registration statement of which this joint proxy statement/prospectus forms a part, Topco Shares issued in the Combinations will not be subject to any restrictions on transfer arising under the Securities Act or the Exchange Act, except for Topco Shares issued to any Ortho shareholder or Quidel stockholder who may be deemed an “affiliate” of Topco after completion of the Combinations. This joint proxy statement/prospectus does not cover resales of Topco Shares received by any person upon completion of the Combinations, and no person is authorized to make any use of this joint proxy statement/prospectus in connection with any resale of Topco Shares.

Listing of Topco Shares on Stock Exchange

Topco Shares currently are not traded or quoted on a stock exchange or quotation system. The parties expect that, following completion of the Combinations, Topco Shares will be listed for trading on Nasdaq, and it is a condition to the parties’ obligations to effect the Combinations that the Topco Shares be authorized for listing on Nasdaq, subject to official notice of issuance.

Delisting and Deregistration of Ortho Shares and Quidel Shares

Promptly after the Ortho Effective Time, the Ortho Shares will be delisted from Nasdaq and deregistered under the Exchange Act, and promptly after the Quidel Effective Time, the Quidel Shares will be delisted from Nasdaq and deregistered under the Exchange Act. Topco will be the successor to Quidel for purposes of Topco’s Nasdaq listing.

Litigation Relating to the Combinations

Since the announcement of the Combinations, one putative complaint has been filed by and purportedly on behalf of an alleged Ortho shareholder: Rydberg v. Ortho Clinical Diagnostics Holdings plc, et al., No. 1:22-cv-01334 filed March 10, 2022 in the United States District Court for the Eastern District of New York (the “Action”).

The Action names as defendants Ortho and the members of Ortho’s Board of Directors. The Action alleges, among other things, that the joint proxy statement/prospectus omits certain information regarding projections of Ortho, Quidel and Topco, the analysis performed by the financial advisor of Ortho, and potential conflicts of interest involving a financial advisor and Ortho’s officers and directors. The Action seeks, among other things, injunctive relief to prevent the Combinations from closing, damages if the Combinations close, and attorneys’ fees. Ortho believes these claims are entirely without merit and that the joint proxy statement/prospectus does not omit any material information about the Combinations.

274

DESCRIPTION OF TOPCO CAPITAL STOCK

General

The following information is a summary of the material terms of the capital stock of Topco (upon effectiveness of the Combinations). You are encouraged to read the Topco Charter and the Topco Bylaws, which, following completion of the Combinations, will be substantially in the forms attached hereto as Exhibit 3.1 and Exhibit 3.2 of this joint proxy statement/prospectus, respectively. For more information, see the comparison of relative rights described in the section entitled “Comparison of Rights of Stockholders of Quidel, Ortho and Topco” of this joint proxy statement/prospectus.

Common Stock

Topco’s authorized capital stock consists of [●] shares of common stock, par value $0.001 per share, and [●] shares of preferred stock, par value $0.001 per share.

Voting. Except as otherwise required by law (and subject to the rights of any other outstanding capital stock under the Topco Charter), each outstanding share of common stock is entitled to vote on each matter on which Topco’s stockholders are entitled to vote, and each holder thereof shall be entitled to one vote for each share of common stock held by such holder. Holders of shares of common stock do not have cumulative voting rights.

Dividends. Holders of Topco Shares have the right to receive dividends when, as and if declared by the Topco board of directors from funds legally available therefor.

Special Meetings and Notice Procedures. The Topco Bylaws provide that special meetings of stockholders may only be called by stockholders of record, as of the record date fixed as provided therein, holding in the aggregate not less than 50% of the voting power of Topco’s issued and outstanding capital stock. In addition, the Topco Bylaws establish an advance written notice procedure for stockholders seeking to nominate candidates for election to the Topco board of directors or to propose matters to be acted upon at stockholders’ meetings. As a result, these provisions of the Topco Bylaws may delay stockholder actions with respect to business combinations or a change in management and may make it more difficult for third parties to acquire control of Topco.

Advanced Notice Bylaws. For director nominations or other business to be properly brought before an annual meeting by a stockholder, such stockholder must generally provide notice to Topco no later than 90 days and no more than 120 days prior to the first anniversary of the date of the prior year’s annual meeting; provided, that if the date of the annual meeting is advanced by more than 30 days prior to or delayed by more than 60 days after the anniversary of the preceding year’s annual meeting, such notice must be delivered no more than 120 days prior to such annual meeting nor less than the later of (i) 90 days prior to such annual meeting and (ii) ten days after the day on which public disclosure of the date of such meeting is first made.

Exclusive Jurisdiction. The Topco Bylaws provide that unless Topco selects or consents in writing to the selection of an alternative forum, (i) the sole and exclusive forum for any complaint by any current or former stockholder asserting any internal corporate claims, to the fullest extent permitted by law, and subject to applicable jurisdictional requirements, shall be the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have, or declines to accept, jurisdiction, another state court or a federal court located within the State of Delaware), and (ii) the sole and exclusive forum for any complaint by any current or former stockholder asserting a cause of action arising under the Securities Act, to the fullest extent permitted by law, shall be the federal district courts of the United States of America.

Delaware Anti-takeover Statute. Topco has opted out of Section 203 of the DGCL, which is a statute that (if applicable) would have served to make certain types of unfriendly or hostile corporate takeovers, or other non-board approved transactions involving a corporation and one or more of its significant stockholders, more difficult.

Other Rights. Holders of Topco Shares do not have any preemptive, subscription or conversion rights under the Topco Charter.

Preferred Stock

The Topco board of directors is authorized to issue from time to time, without further vote or action by the stockholders, up to an aggregate of [●] shares of preferred stock in one or more series. The Topco board of directors is authorized, within the

275

limitations and restrictions stated in the Topco Charter, to determine or alter the rights, preferences, privileges and restrictions granted to or imposed on any wholly unissued series of preferred shares, and the number of shares constituting such series and the designation thereof. No preferred shares are currently outstanding.

Topco currently has no plans to issue any shares of preferred stock, but Topco believes that the ability to issue shares of preferred stock without the expense and delay of a special stockholders’ meeting will provide Topco with increased flexibility in structuring possible future financings and acquisitions, and in meeting other corporate needs that might arise. The Topco board of directors could issue shares of preferred stock having voting, dividend and liquidation rights superior to those of the shares of common stock, which could adversely affect the voting power of the common stockholders, including the loss of voting control to others, and delay, defer or prevent a change in control of Topco without further action by the stockholders. This could discourage an acquisition attempt or other transaction that stockholders might believe to be in their best interests or in which they might receive a premium for their stock over the then-market price of the stock.

If the Topco board of directors were to issue a new series of preferred stock, the issuance of such shares could:

| • |  | decrease the amount of earnings and assets available for distribution to existing holders of Topco Shares;

| • |  | make removal of Topco management more difficult;

| • |  | result in restrictions upon the payment of dividends and other distributions to the existing holders of Topco Shares;

| • |  | delay or prevent a change in control of Topco; and

| • |  | limit the price that investors are willing to pay in the future for Topco Shares.

Registration Rights

Pursuant to the Stockholders Agreement, the Carlyle Stockholder (or its permitted transferees or affiliates) is entitled to demand and piggyback rights with respect to the registration of its Topco Shares under the Securities Act. In certain instances, the Carlyle Stockholder may cause Topco, at Topco’s expense, to file registration statements under the Securities Act covering resales of Topco Shares held by the Carlyle Stockholder (or such permitted transferees or affiliates) or to piggyback on other registration statements in certain circumstances. For more information, see the section entitled “Stockholders Agreement / Deed of Irrevocable Undertaking” of this joint proxy statement/prospectus.

276

THE BUSINESS COMBINATION AGREEMENT

This section of the joint proxy statement/prospectus describes material terms and conditions of the BCA. The description in this section and elsewhere in this joint proxy statement/prospectus is qualified in its entirety by reference to the complete text of the BCA, a copy of which is attached as Exhibit 2.1 and is incorporated by reference into this joint proxy statement/prospectus. This summary may not contain all of the information that is important to you. You should carefully read this entire document, including the full text of the BCA and the other documents referred to therein, for a more complete understanding of the Combinations before making any decisions regarding the Combinations, including approval of the Ortho Scheme or the Merger Proposal, as applicable, as it is the legal document governing the Combinations.

Explanatory Note Regarding the Business Combination Agreement

The BCA and this summary of terms are included to provide you with information regarding the terms of the BCA. Factual disclosures about Quidel, Ortho and Topco contained in this joint proxy statement/prospectus or in the public reports of Quidel, Ortho and Topco filed with the SEC may supplement, update or modify the factual disclosures about Quidel, Ortho and Topco contained in the BCA. See the section entitled “Where You Can Find More Information” of this joint proxy statement/prospectus. The representations, warranties and covenants made in the BCA by Quidel, Ortho, Topco, U.S. Merger Sub, U.S. Holdco Sub and U.S. Holdco Sub 2 were qualified and subject to important limitations agreed to by Quidel, Ortho, Topco, U.S. Merger Sub, U.S. Holdco Sub and U.S. Holdco Sub 2 in connection with negotiating the terms of the BCA. In particular, in your review of the representations and warranties contained in the BCA and described in this summary, it is important to bear in mind that the representations and warranties were negotiated with the principal purpose of establishing circumstances in which a party to the BCA may have the right, subject to certain materiality exceptions, not to consummate the Combinations if the representations and warranties of the other party prove to be untrue due to a change in circumstance or otherwise, and allocating risk among the parties to the BCA, rather than establishing matters as facts. The representations and warranties also may be subject to a contractual standard of materiality different from that generally applicable to shareholders or stockholders and reports and documents filed with the SEC, and in some cases were qualified by the matters contained in the confidential disclosures that Quidel and Ortho each delivered to the other party in connection with the BCA, which disclosures were not reflected in the BCA itself. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this joint proxy statement/prospectus, may have changed since the date on which they were made.

Execution of the Business Combination Agreement

On December 22, 2021, the parties executed the BCA.

Structure and Effective Times

The BCA provides for two transactions, which will occur in immediate succession. First, when the Ortho Scheme Order becomes effective upon the delivery of the Ortho Scheme Order to the Registrar, each issued and outstanding Ortho Share at the Ortho Effective Time (other than Excluded Ortho Shares) shall be transferred to the DR Nominee (or, if the DR Nominee holds the Ortho Shares today, transferred within the DR Nominee) for the benefit and on behalf of Topco in exchange for the consideration described under “Merger Consideration” below.

Immediately following the Ortho Effective Time, U.S. Merger Sub will merge with and into Quidel in a statutory merger under Delaware law, pursuant to which, following the Quidel Effective Time, the independent existence of U.S. Merger Sub will cease, with Quidel surviving as a wholly owned subsidiary of Topco, and pursuant to which each Quidel Share, other than any Quidel Shares held by Quidel, Ortho or U.S. Merger Sub (the “Excluded Quidel Shares”), will automatically be converted into the right to receive the Quidel Merger Consideration of one Topco Share, in each case subject to the terms and conditions of the BCA and as described under “Merger Consideration” below. Immediately following consummation of the Combinations, it is expected that former Quidel stockholders will own approximately 62% of Topco and former Ortho shareholders will own approximately 38% of Topco, on a fully diluted basis, based on the respective capitalizations of Quidel and Ortho as of the date the parties entered into the BCA.

The Quidel Merger will be completed at the Quidel Effective Time, which will immediately follow the Ortho Effective Time. Subject to the satisfaction or waiver of certain conditions contained in the BCA, as described under “Conditions to the Combinations” below, Topco and Ortho are required under the BCA to appear at the Ortho Court Meeting to seek sanctioning of the Ortho Scheme Order under Part 26 of the UK Companies Act.

277

On the date on which the Ortho Scheme Order is filed with the Registrar, and as soon as practicable after such time, and in no event prior thereto, Quidel will file the Quidel Certificate of Merger with the Secretary of State of the State of Delaware, which will provide that the Quidel Merger will become effective on such date.

Immediately following the Combinations, Topco shall transfer 100% of the depositary interests in the issued and outstanding Ortho Shares held by the DR Nominee and the deferred shares in Topco to U.S. Holdco Sub as a contribution to capital and, at least two days following such contribution, U.S. Holdco Sub will transfer such depositary interests and deferred shares to U.S. Holdco Sub 2.

Merger Consideration

Ortho Shares Consideration

The BCA provides that, at the Ortho Effective Time, each Ortho Share issued and outstanding immediately prior to the Ortho Effective Time, other than the Excluded Ortho Shares (if any), will be exchanged for (a) 0.1055 Topco Shares and (b) $7.14 in cash (collectively, the “Ortho Scheme Consideration”), and the Scheme of Arrangement further provides that such exchange shall be settled as soon as reasonably practicable following the Ortho Effective Date and in any event no later than two Business Days thereafter. As of the Ortho Effective Time, the holders of the Ortho Shares (and any holders of depositary interests in Ortho Shares) shall cease to have any rights with respect to the Ortho Shares, except their rights under the Ortho Scheme in accordance with the terms of the BCA. No fractional Topco Shares will be issued to any holders of Ortho Shares and such holders shall receive, in lieu of fractional Topco Shares, cash as described further in “Ortho Shareholder Meetings—Scheme of Arrangement.”

Quidel Shares Consideration

The BCA provides that, at the Quidel Effective Time, each Quidel Share issued and outstanding immediately prior to the Quidel Effective Time, other than Excluded Quidel Shares, will be exchanged for one Topco Share, in accordance with the terms of the BCA. As of the Quidel Effective Time, the holders of the Quidel Shares shall cease to have any rights with respect to the Quidel Shares, except their rights under the Quidel Merger in accordance with the terms of the BCA.

Pursuant to Section 262(b)(1) of the DGCL, Quidel stockholders are not entitled to exercise dissenters’, appraisal, cash exit or similar rights in connection with the Combinations.

Adjustments to Prevent Dilution

In the event that between the date of the BCA and the Ortho Effective Time, the outstanding Quidel Shares or Ortho Shares, or securities convertible into, or exercisable or exchangeable for Quidel Shares or Ortho Shares, change into a different number of shares or a different class by reason of any stock dividend, stock distribution or other similar event, then the Quidel Exchange Ratio or the Ortho Exchange Ratio, as the case may be, will be appropriately adjusted to provide to the stockholders of both Quidel and Ortho the same economic effect as contemplated by the BCA prior to such event.

Exchange of Shares

Ortho Scheme

Topco will appoint a U.S. bank or trust company or other independent financial institution in the United States reasonably satisfactory to Quidel and Ortho (the “Exchange Agent”) which will, among other things, deliver the Ortho Scheme Consideration and the Quidel Merger Consideration to former Ortho shareholders and former Quidel stockholders, respectively. Ortho Shares will be transferred under the Ortho Scheme in accordance with the terms of the BCA, the terms of the Ortho Scheme and the rules and procedures of any depositary or clearing agency through which such shares are held or traded and applicable law. Prior to the Court Sanction Hearing, Quidel will irrevocably commit to Topco and, as may be required, the Court to make available to Topco the Cash Portion, which will be deposited with the Exchange Agent on or before the Ortho Effective Time.

Quidel Merger

Topco will deposit with the Exchange Agent, for the benefit of holders of Quidel Shares, the number of Topco Shares issuable in the Quidel Merger (the “Exchange Fund”).

278

For Quidel Shares represented by certificates, as soon as practicable after the Quidel Effective Time, but in no event later than five days thereafter, Topco will cause the Exchange Agent to mail to each holder of a Quidel Share certificate a letter of transmittal and instructions describing how such holder may exchange its Quidel Shares for the Quidel Merger Consideration in respect of its shares under the BCA. Upon surrender of a certificate (or an affidavit of loss in lieu thereof, and, if required the posting of a bond) for cancellation to the Exchange Agent and delivery of a duly executed letter of transmittal in proper form, the holder of such shares will be entitled to receive the Quidel Merger Consideration (after giving effect to any required tax withholdings). Holders of Quidel Shares represented by certificates will not be entitled to receive the Quidel Merger Consideration or any other payments in respect of their shares under the BCA unless and until such holders have delivered a duly completed and executed letter of transmittal to the Exchange Agent, accompanied by the required share certificates and such other customary documents as may be reasonably required by the Exchange Agent. Surrendered share certificates will be cancelled.

Holders of Quidel Shares in book-entry form through DTC will automatically be entitled to receive, and Topco will cause the Exchange Agent to pay and deliver as promptly as practicable after the Quidel Effective Time, the Quidel Merger Consideration in respect of such shares.

As soon as practicable after the Quidel Effective Time, but in no event later than five days thereafter, Topco will cause the Exchange Agent to deliver to each holder of a Quidel Share that is held in book-entry form, but that is not held through DTC, a letter of transmittal and instructions describing how such holder may exchange its Quidel Shares for the Quidel Merger Consideration.

Lost, Stolen or Destroyed Certificates

If any certificate representing Quidel Shares has been lost, stolen or destroyed, the holder thereof will be entitled to receive, in exchange for such lost, stolen or destroyed Quidel Share certificate, the applicable Quidel Merger Consideration as contemplated by the BCA upon the making of an affidavit to the Exchange Agent by the holder claiming such certificate to be lost, stolen or destroyed and, if required by the Exchange Agent or Topco, the posting by such person of a bond in such sum as it may reasonably direct as indemnity against any claim with respect to such certificate.

No Transfers Following the Quidel Effective Time

As of the Quidel Effective Time, the stock transfer books of Quidel will be closed, and there will be no further registration of transfers on records of Quidel.

Termination of Exchange Fund

Any Topco Shares that remain in the Exchange Fund as of the first anniversary of the Ortho Effective Date will be delivered to Topco by the Exchange Agent if Topco so requires. Thereafter, holders of Quidel Shares will be entitled to look only to Topco with respect to the payment of the Quidel Merger Consideration. If, prior to six years after the Ortho Effective Date (or otherwise immediately prior to such time as the applicable amount would become the property of any governmental entity under applicable law), any holder of Quidel Share certificates or Quidel Shares held in book-entry form has not complied with the procedures set forth in the BCA to receive the Quidel Merger Consideration to which such holder would otherwise be entitled, such Quidel Merger Consideration will, to the extent permitted by applicable law, become the property of Topco, free and clear of all claims or interest of any person previously entitled thereto. Neither Topco nor the Exchange Agent will be liable to any former holder of Quidel Shares for any amount properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

Withholding Taxes

Each of Quidel, Ortho, Topco, the Quidel Merger surviving company, and the Exchange Agent will be entitled to deduct and withhold applicable taxes from the consideration otherwise payable pursuant to the BCA such amounts as it is required to deduct and withhold with respect to the making of such payment. Any amount so withheld will be treated for all purposes as having been paid to such holders.

279

Treatment of Ortho Equity Awards

Under the BCA, awards outstanding under the Ortho Stock Plans will be treated as follows:

Stock Options. At the Ortho Effective Time, each Ortho Stock Option, whether vested or unvested, that is outstanding immediately prior to the Ortho Effective Time will cease to represent an option to acquire Ortho Shares and will be converted into (a) a Topco Stock Option on the same terms and conditions as were applicable to such Ortho Stock Option immediately prior to the Ortho Effective Time, except as adjusted by the BCA, (b) with respect to the portion of such Ortho Stock Option that is vested as of the Ortho Effective Time, the right to receive payment, in cash, equal to the cash consideration payable in respect of the Ortho Shares subject to the vested portion of such Ortho Stock Option and (c) with respect to the portion of such Ortho Stock Option that is not vested as of the Ortho Effective Time, the right to receive payment, in cash, equal to the cash consideration payable in respect of the Ortho Shares subject to the unvested portion of such Ortho Stock Option when it vests in accordance with its terms. The number of Topco Shares subject to each such Topco Stock Option will be equal to the product (rounded down to the nearest whole number) obtained by multiplying (i) the number of Ortho Shares subject to such Ortho Stock Option immediately prior to the Ortho Effective Time by (ii) the Ortho Exchange Ratio, and each such Topco Stock Option will have an exercise price per share (rounded up to the nearest whole cent) equal to (x) the exercise price per Ortho Share of such Ortho Stock Option immediately prior to the Ortho Effective Time divided by (y) the Ortho Exchange Ratio.

Based on the Ortho Stock Options outstanding as of December 20, 2021, and assuming no Ortho Stock Options are exercised between December 20, 2021 and the Ortho Effective Time, 1,375,955 Topco Shares will be issuable pursuant to Topco Stock Options issued in exchange for such Ortho Stock Options.

Restricted Stock Units and Restricted Stock. At the Ortho Effective Time, each Ortho Equity Right that is outstanding immediately prior to the Ortho Effective Time will cease to relate to or represent a right to receive Ortho Shares and will be converted into a Topco Equity Right of the same type and on the same terms and conditions as were applicable to the corresponding Ortho Equity Right immediately prior to the Ortho Effective Time. Upon the subsequent vesting of any portion of such Ortho Equity Right, such portion of the Ortho Equity Right shall also be entitled to a right to receive payment, in cash, equal to the cash consideration in respect of the Ortho Shares subject to the unvested portion of the Ortho Equity Right when it vests in accordance with its terms. The number of Topco Shares covered by each such Topco Equity Right will be equal to the product (rounded to the nearest whole number) obtained by multiplying (i) the number of Ortho Shares subject to such Ortho Equity Right immediately prior to the Ortho Effective Time by (ii) the Ortho Exchange Ratio.

Based on the Ortho Equity Rights outstanding as of December 20, 2021, and assuming none of such rights vest by their terms between December 20, 2021 and the Ortho Effective Time, 58,618 Topco Shares will be issuable pursuant to Topco Equity Rights issued in exchange for such Ortho Equity Rights.

If any Ortho Stock Award is, immediately prior to the Ortho Effective Time, subject to any performance-based vesting based on the attainment of a stock price level or target, such hurdle shall be adjusted to reflect the Ortho Scheme Consideration, and the Ortho board of directors will take all necessary action to effect such adjustment prior to the Ortho Effective Time, conditioned upon the consummation of the Combinations.

Treatment of Quidel Equity Awards

Pursuant to the terms of the BCA, each award of outstanding Quidel Stock Options, Quidel RSUs and Quidel PSUs will be treated as follows:

Stock Options. At the Quidel Effective Time, each outstanding Quidel Stock Option, granted under a Quidel Stock Plan, whether vested or unvested, will automatically, without any action on the part of the holder thereof, cease to represent an option to acquire Quidel Shares and be converted into a Topco Stock Option on the same terms and conditions (including applicable vesting conditions) applicable to such Quidel Stock Option under the applicable Quidel Stock Plan and award agreement in effect immediately prior to the Quidel Effective Time, except as adjusted by the BCA. The number of Topco Shares subject to each such Topco Stock Option will be equal to the number of Quidel Shares subject to such Quidel Stock Option immediately prior to the Quidel Effective Time, and each such Topco Stock Option will have an exercise price per share equal to the exercise price per Quidel Share of such Quidel Stock Option immediately prior to the Quidel Effective Time.

280

Based on the Quidel Stock Options outstanding as of December 22, 2021, and assuming no Quidel Stock Options are exercised between December 22, 2021 and the Quidel Effective Time, 722,034 Topco Shares will be issuable pursuant to Topco Stock Options issued in exchange for such Quidel Stock Options.

Restricted Stock Units. At the Quidel Effective Time, each outstanding Quidel RSU granted under a Quidel Stock Plan will automatically, without any action on the part of the holder thereof, be converted into a Topco RSU on the same terms and conditions (including applicable vesting conditions) applicable to such Quidel RSU under the applicable Quidel Stock Plan and award agreement in effect immediately prior to the Quidel Effective Time. The number of Topco Shares covered by each such Topco RSU will be equal to the number of Quidel Shares subject to such Quidel RSU immediately prior to the Quidel Effective Time.

Based on the Quidel RSUs outstanding as of December 22, 2021, and assuming none of such rights vest by their terms between December 22, 2021 and the Quidel Effective Time, 566,770 Topco Shares will be issuable pursuant to Topco RSUs issued in exchange for such Quidel RSUs.

Performance Restricted Stock Units. At the Quidel Effective Time, each outstanding Quidel PSU granted under a Quidel Stock Plan will automatically, without any action on the part of the holder thereof, be converted into a Topco PSU on the same terms and conditions (including applicable vesting conditions) applicable to such Quidel PSU under the applicable Quidel Stock Plan and award agreement in effect immediately prior to the Quidel Effective Time. The number of Topco Shares covered by each such Topco PSU will be equal to the number of Quidel Shares subject to such Quidel PSU immediately prior to the Quidel Effective Time. The Quidel board of directors, or an applicable committee thereof, may, prior to the Ortho Effective Time make such equitable adjustments, if any, to the applicable performance goals or conditions relating to such Quidel PSU, as the Quidel board of directors may determine to be necessary or appropriate as a result of the consummation of the Combinations, which equitable adjustments shall take effect upon and be subject to the consummation of the Combinations and, in each case, subject to and in accordance with the terms and conditions of the Quidel Stock Plans and Quidel PSU.

Based on the Quidel PSUs outstanding as of December 22, 2021, and assuming none of such rights vest by their terms between December 22, 2021 and the Quidel Effective Time, 19,642 Topco Shares will be issuable pursuant to Topco PSUs issued in exchange for such Quidel PSUs.

Representations and Warranties

The BCA contains representations and warranties that Quidel, on the one hand, and Ortho and Topco, on the other hand, have made to each other as of specific dates and are subject to and qualified by certain information included in certain public filings each of Quidel and Ortho has made. These representations and warranties have been made for the benefit of the other parties to the BCA and may be intended not as statements of fact, but rather as a way of allocating risk to one of the parties if those statements prove to be incorrect. In addition, the assertions embodied in the representations and warranties are qualified by information in a confidential disclosure letter provided by Quidel to Ortho, on the one hand, and in a confidential disclosure letter provided by Ortho to Quidel, on the other hand, delivered in connection with the execution of the BCA. While the parties do not believe that these disclosure letters contain information required to be publicly disclosed under the applicable securities laws (other than information that has already been so disclosed), the disclosure letters do contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the BCA. Accordingly, you should not rely on the representations and warranties as current characterizations of factual information about Quidel or Ortho since they were made as of specific dates, may be intended merely as risk allocation mechanisms between Quidel and Ortho and are modified in important part by the confidential disclosure letters.

The BCA contains representations and warranties from Quidel to Ortho, on the one hand, and from Ortho to Quidel, on the other hand, in each case regarding the following:

| • |  | organization, existence, good standing (if applicable), qualification to do business and corporate or other legal power;

| • |  | capital structure, including the number of shares of capital stock, stock options and other equity-based awards outstanding;

| • |  | corporate power and authority with respect to the due execution and delivery of the BCA and completion of the Combinations, the authorization and adoption of the BCA and the Combinations by the board of directors or similar governing body and the enforceability of the BCA;

281

| • |  | absence of breaches of, or conflicts with, organizational documents, certain contracts and applicable laws as a result of entry into, or consummation of the transactions contemplated by, the BCA;

| • |  | required consents, approvals, authorizations or permits of, or filings or registrations with or notifications to, governmental entities;

| • |  | compliance with listing and corporate governance rules and regulations of Nasdaq and the SEC;

| • |  | conduct of business in the ordinary course of business consistent with past practice since December 31, 2020, in the case of Quidel, and January 3, 2021, in the case of Ortho;

| • |  | absence of a Material Adverse Effect on Quidel or Ortho since December 31, 2020 or January 3, 2021, respectively;

| • |  | compliance with laws and required permits;

| • |  | absence of any civil, criminal, administrative or regulatory actions, suits, claims, litigation, hearings, investigations or proceedings pending or, to the knowledge of the parties, threatened;

| • |  | absence of any judgments, orders, decisions, writs, injunctions, decrees, stipulations, legal or arbitration awards, rulings or other findings or agency requirements of any governmental entity outstanding against either party;

| • |  | absence of undisclosed liabilities;

| • |  | employee benefit matters and compliance with the Employee Retirement Income Security Act of 1974, as amended, as applicable;

| • |  | compliance with tax laws and other tax matters;

| • |  | collective bargaining agreements and other labor matters;

| • |  | material contracts;

| • |  | intellectual property;

| • |  | data protection;

| • |  | real and personal property;

| • |  | environmental matters;

| • |  | significant customers and suppliers;

| • |  | absence of related party transactions;

| • |  | accuracy of information supplied in connection with this joint proxy statement/prospectus and other public filings; and

| • |  | brokers, finders or investment bankers entitled to fees or commissions in connection with the Combinations.

Certain of the representations and warranties in the BCA are subject to knowledge qualifications, which means that those representations and warranties would not be deemed untrue, inaccurate or incorrect as a result of matters of which certain officers of the party making the representation did not have actual knowledge. Many of the representations and warranties in the BCA are qualified by a materiality or a Material Adverse Effect standard (that is, they will not be deemed to be untrue or incorrect unless their failure to be true or correct is material or would result in a Material Adverse Effect on the company making such representation or warranty).

282

Subject to certain exclusions (which are summarized below), for purposes of the BCA, a “Material Adverse Effect,” when used in reference to Quidel, Ortho, or, following the consummation of the Combinations, Topco, as applicable, means any event, change, circumstance, effect, occurrence, state of facts or development (each, an “Effect”) that, individually or in the aggregate with all other such Effects, has a material adverse effect on the condition (financial or otherwise), assets, liabilities, business or results of operations of Quidel and its subsidiaries, Ortho and its subsidiaries, or, following the consummation of the Combinations, Topco and its subsidiaries, in each case taken as a whole, respectively (including for purposes of the references to Quidel, Ortho and Topco in the proviso below); provided, however, that none of the following, and no effect resulting from the following (to the extent attributable to the following), will constitute a Material Adverse Effect or be considered in determining whether a Material Adverse Effect has occurred or would be reasonably likely to occur:

| • |  | any change or development in general or industry economic or regulatory, legislative or political conditions or securities, credit, financial or other capital markets conditions, in each case in the United States or any other jurisdiction, except to the extent that such change or development affects Quidel, Ortho or Topco, respectively, in a disproportionate manner relative to other businesses operating in the industries in which Quidel, Ortho or Topco, respectively, operates;

| • |  | any change or development to the extent resulting from the execution and delivery of the BCA or the public announcement, pendency or consummation of the Combinations or any of the other transactions contemplated by the BCA (in the case of execution and delivery of the BCA, or consummation, other than for purposes of any representation or warranty the purpose of which is to address the consequences resulting therefrom, including stockholder litigation and the impact of such changes or developments on the relationships, contractual or otherwise, of such party or any of its subsidiaries with employees, labor unions, clients, customers, suppliers or partners);

| • |  | any change or development to the extent resulting from any failure of Quidel, Ortho or Topco, respectively, to meet any internal or published projections, forecasts, estimates or predictions in respect of revenues, earnings or other financial or operating metrics for any period (it being understood that the facts and circumstances giving rise to such failure may be deemed to constitute, and may be taken into account in determining whether there has been, a Material Adverse Effect);

| • |  | any change, in and of itself, in the market price, credit rating (with respect to such party or its securities) or trading volume of such party’s securities (it being understood that the facts and circumstances giving rise to such change may be deemed to constitute, and may be taken into account in determining whether there has been, a Material Adverse Effect);

| • |  | any change in applicable law or GAAP (or, in each case, authoritative interpretation thereof), except to the extent that such change or development affects Quidel, Ortho or Topco, respectively, in a disproportionate manner relative to other businesses operating in the industries in which Quidel, Ortho or Topco, respectively, operates;

| • |  | geopolitical conditions, the outbreak of hostilities, any acts of war, sabotage or terrorism, any pandemic, epidemic or disease outbreak (including SARS-CoV-2, COVID-19, and any evolutions or other mutations thereof, collectively, “COVID-19”) or any escalation or worsening of any such hostilities, acts of war, sabotage, terrorism, pandemic, epidemic or disease outbreak threatened or underway as of the date of the BCA, except to the extent that such change or development affects Quidel, Ortho or Topco, respectively, in a disproportionate manner relative to other businesses operating in the industries in which Quidel, Ortho or Topco, respectively, operates;

| • |  | any hurricane, tornado, flood, earthquake or other natural disaster, except to the extent that such change or development affects Quidel, Ortho or Topco, respectively, in a disproportionate manner relative to other businesses operating in the industries in which Quidel, Ortho or Topco, respectively, operates; or

| • |  | any change or development to the extent resulting from any action by Quidel, Ortho or Topco, respectively, that is expressly required to be taken by the BCA (other than any actions required to be taken under the section of the BCA relating to the operations of the businesses after signing of the BCA and prior to the consummation of the Combinations).

The representations and warranties of each of the parties to the BCA do not survive the consummation of the Combinations.

Conduct of Business Prior to the Effective Times

In the BCA, each of Quidel and Ortho has agreed that until the Quidel Effective Time or termination of the BCA in accordance with its terms, subject to certain specified exceptions, and unless the other party approves in writing (which

Acquisition Proposals

Pursuant to the terms of the BCA, each of Quidel and Ortho agrees that it will not, and agrees to cause its subsidiaries and its and their respective officers, directors and employees not to (and use reasonable best efforts to cause its and its subsidiaries’ other representatives not to), directly or indirectly:

| • |  | initiate, solicit or knowingly facilitate or encourage (including by way of furnishing information) any inquiries, discussions or the making, submission or announcement of any proposal, request or offer that constitutes, or could reasonably be expected to lead to or result in, an Acquisition Proposal;

| • |  | have any discussion with any person relating to an Acquisition Proposal (other than, solely with respect to an Acquisition Proposal that does not result from a material breach of this provision, to clarify the terms of an Acquisition Proposal submitted to such party after the date of the BCA for the sole purpose of enabling the Quidel

285

| • |  | provide any non-public or confidential information or data or afford access to its books or records or directors, officers, employees or advisors, to any person in relation to an Acquisition Proposal;

| • |  | terminate, amend, release, modify or fail to enforce any provision of, or grant any permission, waiver or request under, any standstill, confidentiality or similar agreement entered into by it or any of its subsidiaries (other than to the extent the Quidel board of directors or Ortho board of directors, as applicable, determines in good faith, after consultation with its financial and outside legal advisors, that failure to take any such actions under this provision would reasonably be expected to be inconsistent with the directors’ fiduciary duties under applicable law);

| • |  | approve or recommend, or propose publicly to approve or recommend, any Acquisition Proposal;

| • |  | propose publicly or agree to do any of the foregoing related to any Acquisition Proposal.

Under the BCA and throughout this joint proxy statement/prospectus, an “Acquisition Proposal” with respect to Quidel or Ortho means any offer or proposal for, or any indication of interest in, (a) any direct or indirect acquisition or purchase, in a single transaction or a series of related transactions, of Quidel or Ortho, as applicable, or any of its subsidiaries that constitutes 15% or more of the consolidated gross revenue or consolidated gross assets of Quidel or Ortho, as applicable, and its subsidiaries, taken as a whole (such subsidiary, a “Major Subsidiary”); (b) any direct or indirect acquisition or purchase of (i) 15% or more of any class of equity securities or voting power or 15% or more of the consolidated gross assets of Quidel or Ortho, as applicable, or (ii) 15% or more of any class of equity securities or voting power of any of its Major Subsidiaries; (c) any tender offer that, if consummated, would result in any person beneficially owning 15% or more of any class of equity securities or voting power of Quidel or Ortho, as applicable; or (d) any merger, reorganization, share exchange, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving Quidel or Ortho, as applicable, or any Major Subsidiary of Quidel or Ortho, as applicable, in each case, with a person other than the other party or any of its affiliates.

Existing Discussions or Negotiations

Pursuant to the terms of the BCA, each of Quidel and Ortho agrees that it will immediately cease and cause to be terminated any activities, discussions or negotiations existing as of the date of the BCA with any persons conducted prior to the signing of the BCA with respect to any Acquisition Proposal (or that could reasonably be expected to lead to an Acquisition Proposal), and request that any such person promptly return and destroy (and confirm destruction of) all non-public information. Unless the BCA will have been earlier terminated, neither Quidel nor Ortho will submit to the vote of its stockholders any Acquisition Proposal other than the Combinations.

Superior Proposals and Intervening Events

Pursuant to the terms of the BCA, if (a) in the case of Quidel, prior to the approval and adoption of the BCA by the holders of a majority of the outstanding Quidel Shares entitled to vote thereon (the “Quidel Requisite Vote”) and (b) in the case of Ortho, prior to the approval of the Ortho shareholders to the Ortho board of director’s implementation of the Ortho Scheme, adoption of the new Ortho articles of association (subject to any further amendments as the parties may agree) and the ancillary matters contemplated by the BCA (the “Ortho Requisite Vote”), (i) Quidel or Ortho, respectively, has received a bona fide Acquisition Proposal from a third party that was not received or obtained as a result of any violation of these provisions of the BCA, which the Quidel board of directors or the Ortho board of directors, respectively, determines in good faith (after consultation with its outside legal counsel and financial advisors) constitutes, or would reasonably be expected to lead to, a Superior Proposal (as defined below) and (ii) the Quidel board of directors or the Ortho board of directors, respectively, determines in good faith (after consultation with its outside legal counsel) that failure to take such action would be inconsistent with the directors’ fiduciary duties under applicable law, then Quidel or Ortho, as applicable, may (x) furnish

286

non-public information to such person that has delivered such bona fide Acquisition Proposal and (y) engage in discussions or negotiations with such person with respect to the Acquisition Proposal. Under such circumstances, and prior to furnishing such information or engaging in any such discussion or negotiations, the applicable party must have received an executed confidentiality and standstill agreement from the proposing party, and any non-public information being provided to such proposing party not previously provided or made available to Quidel or Ortho, as applicable, will be made available to such party within 24 hours.

At any time prior to the earlier of (a) the receipt by Quidel of the Quidel Requisite Vote or receipt by Ortho of the Ortho Requisite Vote, as applicable, or (b) the termination of the BCA in accordance with its terms, subject to compliance with the provisions set forth below, the Quidel board of directors and the Ortho board of directors, respectively, will be entitled to make a Quidel Change in Recommendation or an Ortho Change in Recommendation, respectively, in each case (i) if such party receives a Superior Proposal or (ii) in response to an Intervening Event (as defined below), provided that, in each case, only to the extent such board of directors determines in good faith (after consultation with its outside legal counsel) that the failure to make such a change in recommendation would be inconsistent with its fiduciary duties under applicable law.

Neither of the Quidel board of directors nor the Ortho board of directors will be entitled to make a Quidel Change in Recommendation or an Ortho Change in Recommendation, respectively, unless (i) such party is in compliance with the relevant provisions of the BCA, (ii) such party provides the other with a written notice that it intends to make such a change in recommendation, (iii) such party complies with a five Business Day negotiation period with the other parties to the BCA to make such adjustments in the terms and conditions of the BCA so that any Superior Proposal ceases to constitute a Superior Proposal or, with respect to an Intervening Event, as would permit such board of directors to not change their recommendation with respect to the Combinations and (iv) such board of directors determines in good faith, after consultation with its outside legal and financial advisors, that such Superior Proposal continues to constitute a Superior Proposal or, as applicable, with respect to an Intervening Event, that its fiduciary duties still require it to make a Quidel Change in Recommendation or an Ortho Change in Recommendation, as applicable. Any amendment to the financial terms or any other material amendment of a Superior Proposal, or any material change to the facts and circumstances relating to an Intervening Event, as applicable, will require delivery of a new written notice described in the foregoing clause (ii), with a new notice period, but the reference to a “five Business Day negotiation period” in the preceding clause (iii) will be deemed to be a reference to a “three Business Day negotiation period.”

Under the BCA and throughout this joint proxy statement/prospectus, a “Superior Proposal” means, with respect to Quidel or Ortho, a bona fide Acquisition Proposal that did not result from a material breach of these provisions of the BCA and as to which the party recipient of the Acquisition Proposal complied with the applicable provisions of the BCA for or in respect of 80% or more of the outstanding Quidel Shares or Ortho Shares (as applicable) or 80% or more of the assets of Quidel and its subsidiaries, on a consolidated basis, or Ortho and its subsidiaries, on a consolidated basis, as applicable, in each case on terms that the Quidel board of directors or the Ortho board of directors, as applicable, determines in good faith (following receipt of the advice of its financial advisors and outside legal counsel) is reasonably likely to be consummated in accordance with its terms and, taking into account, among other things, (a) all legal, financial, antitrust or other regulatory, timing and other aspects of the Acquisition Proposal and the BCA deemed relevant by such board of directors (including conditions to, expected timing and risks of consummation of, and the ability of the party making such proposal to obtain financing for such Acquisition Proposal), (b) any improved terms that Ortho (in the case of an Acquisition Proposal for Quidel) or Quidel (in the case of an Acquisition Proposal for Ortho) may have offered pursuant to this section is more favorable from a financial point of view to Quidel and its stockholders or Ortho and its shareholders, as the case may be, than the Combinations (after taking into account any such improved terms) and (c) the value of the synergies expected to be recognized as a result of the Combinations.

Under the BCA and throughout this joint proxy statement/prospectus, an “Intervening Event” means any material event or development or material change in circumstances first occurring after the date of the BCA and prior to, in the case of Quidel, receipt by Quidel of the Quidel Requisite Vote and, in the case of Ortho, receipt by Ortho of the Ortho Requisite Vote, to the extent that such event, development or change in circumstances was not reasonably foreseeable as of or prior to the date of the BCA; provided, however, that in no event shall the following events, developments or changes in circumstances constitute an Intervening Event: (a) the receipt, existence or terms of an Acquisition Proposal or any matter relating thereto or consequence thereof, or (b) changes in the market price or trading volume of Ortho Shares or Quidel Shares or the fact that a party meets or exceeds internal or published projections, forecasts or revenue or earnings predictions for any period; provided, however, that the underlying causes of such change or fact shall not be excluded by this clause (b).

287

Notice

Pursuant to the terms of the BCA, from and after the date of the BCA, Quidel or Ortho, as applicable, will promptly (and in any event within 24 hours) notify the other party orally and in writing in the event that it, one of its subsidiaries or any of its representatives receives (i) any Acquisition Proposal, (ii) any request for non-public information relating to such party or any of its subsidiaries, other than requests for information in the ordinary and usual course of business and consistent with past practice and unrelated to an Acquisition Proposal, or (iii) any inquiry or request for discussions or negotiations regarding any Acquisition Proposal. Such notice must include the identity of such person and provide an unredacted copy of such Acquisition Proposal, inquiry or request (or, where no such copy is available, a reasonably detailed description of such Acquisition Proposal, inquiry or request), including any debt financing materials related thereto, if any. Subject to applicable law, Quidel or Ortho, as applicable, will keep the other party reasonably informed on a current basis of the status of any Acquisition Proposal, inquiry or request, and any material developments, discussions and negotiations related thereto.

Certain Permitted Disclosure

Nothing in the BCA will prevent Quidel or Ortho from complying with its disclosure obligations under applicable laws with regard to a competing Acquisition Proposal, except that Quidel and Ortho must nevertheless comply with their obligations under the BCA and any such disclosure (other than a “stop, look and listen” communication or similar communication contemplated by Section 14d 9(f) under the Exchange Act) shall be deemed to be a Quidel Change in Recommendation or an Ortho Change in Recommendation, as applicable, unless the Quidel board of directors or the Ortho board of directors, as applicable, expressly reaffirms its recommendation to its stockholders in favor of the approval of the BCA and the Combinations in such disclosure.

Stockholder Meetings

Quidel will take, in accordance with applicable law, the applicable rules and regulations of the SEC and Nasdaq and its organizational documents, all action necessary to convene the Quidel Stockholders’ Meeting as promptly as practicable after the later of (a) the expiration of any creditor rights opposition period under English law and (b) the date the Registration Statement is declared effective. Quidel will, unless a Quidel Change in Recommendation has been made in accordance with the BCA, use its reasonable best efforts to solicit from its stockholders proxies in favor of the adoption of the BCA and to take all other action reasonably necessary or advisable to secure the Quidel Requisite Vote. Any Quidel Change in Recommendation shall not limit or modify the obligation of Quidel to present the BCA for adoption at a meeting of its stockholders, and, if the BCA is not otherwise terminated by either Quidel or Ortho in accordance with the terms thereof, the BCA and the transactions contemplated thereby shall be submitted to the stockholders of Quidel at such meeting of the Quidel stockholders for the purpose of obtaining the Quidel Requisite Vote, except in the event of a Quidel Change in Recommendation made in accordance with the terms of the BCA in response to a Superior Proposal for Quidel that (i) includes only cash consideration and (ii) is fully financed and does not include any financing condition (including any financing contingency to the right of Quidel to seek specific performance) (a “Quidel All Cash Superior Proposal”).

Ortho will take, in accordance with applicable law, the applicable rules and regulations of the SEC and Nasdaq and its organizational documents, all action necessary to convene a meeting of its shareholders in accordance with Part 26 of the UK Companies Act to approve the Ortho Scheme, such as the Ortho Court Meeting, and a general meeting of its shareholders to adopt new articles of association and to resolve and approve the Ortho board of directors implementing the Ortho Scheme, and other matters as specified in the BCA, such as the Ortho General Meeting, as promptly as practicable after the later of (a) the expiration of any creditor rights opposition period under English law and (b) the date the Registration Statement is declared effective. Ortho will, unless an Ortho Change in Recommendation has been made in accordance with the BCA, use its reasonable best efforts to solicit from its shareholders proxies in favor of the adoption of the terms relating to the Ortho Scheme and to take all other action reasonably necessary or advisable to secure the Ortho Requisite Vote. Any Ortho Change in Recommendation shall not limit or modify the obligation of Ortho to present the BCA for adoption at a meeting of its shareholders, and, if the BCA is not otherwise terminated by either Quidel or Ortho in accordance with the terms thereof, the BCA and the transactions contemplated thereby shall be submitted to the shareholders of Ortho at the Ortho Shareholder Meetings for the purpose of obtaining the Ortho Requisite Vote, except in the event of an Ortho Change in Recommendation made in accordance with the terms of the BCA in response to an Ortho All Cash Superior Proposal.

In accordance with the timetable for the Ortho Scheme and subject to any directions or requirements of the Court, Quidel and Ortho will each use their commercially reasonable efforts to cause the Quidel Stockholders’ Meeting and the Ortho Shareholder Meetings to be held on the same date.

288

Efforts to Complete the Combinations

In order to facilitate completion of the Combinations, the parties to the BCA, subject to certain exceptions, have agreed to use (and cause their respective subsidiaries to use) their respective reasonable best efforts to take or cause to be taken all actions, and do or cause to be done all things, necessary, proper or advisable on their part under the BCA and applicable law to consummate the Combinations and the other transactions contemplated by the BCA as soon as practicable, including:

| • |  | preparing and filing all documentation to effect all necessary notices, reports and other filings as promptly as practicable and obtaining as promptly as practicable all consents, registrations, approvals, authorizations and other permits (including approvals related to applicable competition and antitrust laws) necessary or advisable to be obtained from any governmental entity or any self-regulatory organization in order to consummate the Combinations,

| • |  | using their reasonable best efforts to resolve any objections as may be asserted with respect to the Combinations under any laws, including defending and contesting (through litigation on the merits and any appeals) any legal proceedings, whether judicial or administrative or otherwise, challenging the BCA or the consummation of the transactions contemplated thereby, including seeking to have any order entered by any court or other governmental entity vacated or reversed, and

| • |  | executing and delivering any additional instruments necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, the BCA pursuant to its terms and conditions.

Quidel and Ortho will each provide the other party and/or its counsel with a reasonable advance opportunity to review and comment upon and consider in good faith the views of the other party in connection with all submissions, filings or communications, and agree not to participate independently in any meeting with any governmental entity or self-regulatory organization in connection with the Combinations. Subject to applicable law, Quidel and Ortho will keep each other apprised of all correspondence and discussions with any governmental entity or any self-regulatory organization in connection with the transactions contemplated by the BCA. Further, Quidel and Ortho will keep the other apprised of the status of matters relating to the completion of the transactions contemplated by the BCA.

Indemnification and Insurance

The BCA provides that, to the extent permitted by applicable law, for a period of six years from and after completion of the Combinations, Topco will indemnify and hold harmless and provide advancement of expenses to each past and present (as of completion of the Combinations) director, officer, and employee of Quidel, Ortho or any of their subsidiaries against all costs or expenses (including reasonable attorneys’ fees and disbursements), judgments, inquiries, fines, losses, claims, damages or liabilities incurred by such individual in connection with any civil, criminal, administrative or investigative proceeding arising out of or pertaining to any act or omission of such director, officer or employee prior to completion of the Combinations (i) in each case, to the same extent as such person is indemnified or has the right to advancement of expenses as of the date of the BCA by Quidel, Ortho or their subsidiaries, as applicable, pursuant to the organizational documents and indemnification agreements thereof and (ii) to the fullest extent permitted by applicable law.

The BCA further provides that, for a period of not less than six years after completion of the Combinations, the organizational documents of Topco (and any successor thereto) will contain provisions providing for the elimination of liability of directors, indemnification of officers and directors and advancement of expenses to the fullest extent permitted by applicable law. Additionally, Topco will purchase a six-year “tail” prepaid policy on terms and conditions no less advantageous than the current directors’ and officers’ liability insurance and fiduciary liability insurance maintained by each of Quidel and Ortho for the benefit of Quidel’s and Ortho’s officers and directors; provided that the amount paid for such policy shall not exceed, for each of Quidel and Ortho, 300% of the annual premiums currently paid by Quidel or Ortho, as applicable, for such policy; provided further, that with respect to Quidel’s officers and directors, Quidel may, in lieu of Topco’s purchase of a “tail” prepaid policy, elect to continue coverage for the insured under its current directors’ and officers’ liability insurance and fiduciary liability insurance.

Employee Matters

Quidel and Ortho agreed that continuing employees of each of Quidel and its subsidiaries (each, a “Quidel Continuing Employee”) and Ortho and its subsidiaries (each, an “Ortho Continuing Employee”) shall, until the first anniversary of the Quidel Effective Time and the Ortho Effective Time, receive base salary or base wage, severance benefit protections and

289

pension and welfare benefits that are no less favorable, in the aggregate, than those provided to such employees immediately prior to the Quidel Effective Time or the Ortho Effective Time, as applicable; provided, however, that the requirements of the preceding sentence shall not apply to Quidel Continuing Employees or Ortho Continuing Employees who are covered by a collective bargaining agreement, union, labor or similar contract.

With respect to any benefit plan in which a Quidel Continuing Employee or Ortho Continuing Employee first becomes eligible to participate on or after the Quidel Effective Time or Ortho Effective Time, respectively (a “Relevant Benefit Plan”), each party shall use reasonable best efforts to (a) cause any pre-existing conditions or limitations and eligibility waiting periods under any of its group health plans which is a Relevant Benefit Plan to be waived with respect to the other party’s continuing employees and their eligible dependents, (b) give the other party’s continuing employees credit for the plan year in which the Quidel Effective Time or Ortho Effective Time, respectively, occurs (or the plan year in which any applicable continuing employee first becomes eligible to participate in the applicable Relevant Benefit Plan, if later) towards applicable deductibles and annual out-of-pocket limits for medical expenses incurred during the plan year but prior to the Quidel Effective Time or Ortho Effective Time, respectively (or eligibility date, as applicable), for which payment has been made and (c) give the other party’s continuing employees service credit for such continuing employees’ employment with the other party for purposes of vesting, benefit accrual and eligibility to participate under each applicable Relevant Benefit Plan, as if such service had been performed with such party, except for benefit accrual under defined benefit pension plans, for purposes of qualifying for subsidized early retirement benefits (unless otherwise required under applicable law) or to the extent it would result in a duplication of benefits.

Corporate Governance Matters

Prior to the Ortho Effective Time, the sole stockholder of Topco will adopt the [Topco Charter] and the Topco board of directors will adopt the [Topco Bylaws], in each case to take effect as of the Ortho Effective Time (or prior to such time if mutually agreed by the parties). The [Topco Charter] and [Topco Bylaws] will remain in effect as of the Quidel Effective Time.

Pursuant to the terms of the BCA, the parties will cause the Topco board of directors to consist, at the Ortho Effective Time, of 12 members, comprised of: (a) eight members designated by Quidel, expected to consist of Messrs. Bryant, Buechler, Michael, Strobeck, Widder and Wilkins and Mses. Polan and Rhoads, each of whom, other than Mr. Bryant, qualifies as an “independent director” under applicable rules of Nasdaq, and (b) four members designated by Ortho, at least two of whom will qualify as an “independent director” under applicable rules of Nasdaq. In connection with the BCA, Ortho and the Carlyle Stockholder executed a letter agreement pursuant to which Ortho agrees that, at the closing of the Combinations, the Ortho designees to the Topco board of directors will include two Carlyle nominees.

In addition, pursuant to the terms of the BCA, at the Ortho Effective Time, the Topco board of directors shall constitute the following committees, each of which shall consist of one member designated by Ortho and no less than two members designated by Quidel, in each case subject to applicable legal and regulatory requirements: (a) the Audit Committee, (b) the Nominating and Governance Committee and (c) the Compensation Committee.

Upon the consummation of the Combinations, unless otherwise agreed by Quidel and Ortho, Douglas Bryant will serve as the Chair and Chief Executive Officer, Robert Bujarski will serve as the President and Chief Operating Officer, Joseph Busky will serve as the Chief Financial Officer, and Michael Iskra will serve as the Chief Commercial Officer, in each case of Topco.

| • |  | by the mutual written consent of Quidel and Ortho;

| • |  | by either Quidel or Ortho, if the Ortho Effective Time has not occurred by September 22, 2022 (the “Termination Date”); provided, however, that such date shall automatically be extended to January 22, 2023, if the only conditions that have not been satisfied (other than those conditions that Quidel and Ortho have mutually agreed to waive, if and to the extent that such waiver is permitted by applicable law, and other than those conditions that by their nature can only be satisfied at or immediately prior to the Scheme Effective Date) are one or more of the

292

| conditions set forth in (a) clause (iii) under “Conditions to the Combinations” above to the extent relating to an approval required by clause (v) under “Conditions to the Combinations” above or (b) clause (v) under “Conditions to the Combinations” above; provided, further, that the right to terminate the BCA pursuant to this provision may not be exercised by any party whose failure to perform any material covenant or obligation under the BCA has been the primary cause of, or primarily resulted in, the failure of any such closing condition to be satisfied on or before the Termination Date;

| • |  | by either Quidel or Ortho, if (a) the Quidel Requisite Vote has not been obtained at the Quidel Stockholders’ Meeting (or at any adjournment or postponement thereof) or (b) the Ortho Requisite Vote has not been obtained at the Ortho Shareholder Meetings (or at any adjournment or postponement thereof) or the Ortho Scheme is not sanctioned and the Ortho Scheme Order is not issued by the Court;

| • |  | by either Quidel or Ortho, if any governmental entity that must grant a required regulatory approval has denied such grant in writing and such denial has become final, binding and non-appealable, or any order permanently restraining, enjoining or otherwise prohibiting consummation of the Combinations has become final and non-appealable;

| • |  | by Quidel, at any time prior to the receipt of the Ortho Requisite Vote, if the Ortho board of directors has effected an Ortho Change in Recommendation (whether or not in compliance with the applicable provisions of the BCA);

| • |  | by Quidel, at any time prior to the Ortho Effective Time, if Ortho breaches or fails to perform any of its covenants or agreements contained in the BCA, or if any of the representations or warranties of Ortho contained therein fails to be true and correct, which breach or failure (a) would give rise to the failure of the conditions to Quidel’s obligation to close and (b) is not reasonably capable of being cured by Ortho by the Termination Date or is not cured by Ortho within 45 days after receiving written notice from Quidel, unless Quidel’s failure to perform any material covenant or obligation under the BCA has been the primary cause of, or primarily resulted in, the failure of any such closing condition to be satisfied on or before the Termination Date;

| • |  | by Quidel, at any time prior to the receipt of the Quidel Requisite Vote, if the Quidel board of directors has effected a Quidel Change in Recommendation in compliance with the BCA in response to a Quidel All Cash Superior Proposal and in order for Quidel to enter into a merger agreement, acquisition agreement or other similar agreement that the Quidel board of directors has authorized and directed Quidel to execute with respect to such Quidel All Cash Superior Proposal; provided, however, that the BCA may not be so terminated unless (a) prior to or simultaneously with such termination the Quidel Termination Payment (as defined below) has been made in full to Ortho, and (b) simultaneously or promptly following such termination Quidel enters into such agreement;

| • |  | by Ortho, at any time prior to the receipt of the Ortho Requisite Vote, if the Ortho board of directors has effected an Ortho Change in Recommendation in compliance with the BCA in response to an Ortho All Cash Superior Proposal and in order for Ortho to enter into a merger agreement, acquisition agreement or other similar agreement that the Ortho board of directors has authorized and directed Ortho to execute with respect to such Ortho All Cash Superior Proposal; provided, however, that the BCA may not be so terminated unless (a) prior to or simultaneously with such termination the Ortho Termination Payment (as defined below) has been made in full to Quidel, and (b) simultaneously or promptly following such termination Ortho enters into such agreement.

In the event the BCA is terminated by either Quidel or Ortho, the BCA will become void and of no effect and there will be no liability or obligation on the part of any party or any of their respective directors, officers, employees, agents, legal and financial advisors or other representatives, in each case, except with respect to certain obligations to pay certain expenses and termination fees provided for under the BCA, as described in the section entitled “Expenses and Termination Fees” below. Notwithstanding the foregoing, the termination of the BCA will not relieve any party from liability for any fraud or willful

293

and material breach of any of its representations, warranties, covenants or agreements set forth in the BCA. In the event of any such termination, the parties will cooperate with each other in connection with the withdrawal of any applications to, or termination of proceedings before, any governmental entity or self-regulatory organization in connection with the transactions contemplated by the BCA.

Expenses and Termination Fees

All costs and expenses incurred in connection with the BCA and the Combinations and the other transactions contemplated by the BCA generally are to be paid by the party incurring such costs and expenses, but Quidel and Ortho will share equally all expenses associated with antitrust filings, the Nasdaq listing application and the filing, printing and mailing of this joint proxy statement/prospectus, the Registration Statement and other disclosure documents required in connection with the Combinations.

Quidel must pay Ortho a termination fee of $207,839,918.46 (the “Quidel Termination Payment”) if:

| • |  | the BCA is terminated by Ortho, as a result of a Quidel Change in Recommendation;

| • |  | the BCA is terminated by either Quidel or Ortho if (i) the Combinations are not consummated by the Termination Date or (ii) the Quidel Requisite Vote has not been obtained at the Quidel Stockholders’ Meeting and, at the time of such termination, Ortho had a right to terminate as a result of a Quidel Change in Recommendation;

| • |  | (a) an Acquisition Proposal for Quidel shall have been publicly announced or made publicly known or otherwise communicated or made known to Quidel management or the Quidel board of directors (or any third party shall have publicly announced, communicated or made known a bona fide intention, whether or not conditional, to make a proposal with respect to an Acquisition Proposal) and not withdrawn prior to termination or such vote to adopt the BCA, as applicable, at any time after the date of the BCA and (b) the BCA is subsequently terminated by Ortho as a result of Quidel’s breach of the BCA or is terminated by either Quidel or Ortho because (i) the Combinations are not consummated by the Termination Date or (ii) the Quidel Requisite Vote has not been obtained at the Quidel Stockholders’ Meeting and, at the time of such termination, Ortho had a right to terminate the BCA as a result of a failure by Quidel to perform any of its covenants or agreements contained in the BCA;

| • |  | the BCA is terminated by Quidel in connection with a Quidel All Cash Superior Proposal, subject to certain additional conditions; or

| • |  | (a) an Acquisition Proposal for Quidel has been publicly announced or made publicly known or otherwise communicated or made known to Quidel management or the Quidel board of directors (or any third party shall have publicly announced, communicated or made known a bona fide intention, whether or not conditional, to make a proposal with respect to an Acquisition Proposal) and not withdrawn prior to termination or such vote to adopt the BCA, as applicable, at any time after the date of the BCA, (b) the BCA is subsequently terminated by Quidel or Ortho because (i) the Combinations are not consummated by the Termination Date or (ii) the Quidel Requisite Vote has not been obtained at the Quidel Stockholders’ Meeting, and (c) within nine months of such termination, Quidel or any of its subsidiaries executes an acquisition agreement with respect to, or consummates, or approves or recommends to the Quidel stockholders to accept, any Acquisition Proposal (provided that, for purposes of this clause (c), the term “Acquisition Proposal” is defined as in the section entitled “The Business Combination Agreement—Acquisition Proposals” of this joint proxy statement/prospectus, except that each reference to “15% or more” in the definition of “Acquisition Proposal” and “Major Subsidiary” shall be deemed to be a reference to “50% or more”).

In the event that the BCA is terminated because the Quidel Requisite Vote has not been obtained at the Quidel Stockholders’ Meeting, and the Quidel Termination Payment is not otherwise payable, then Quidel shall pay, or cause to be paid, to Ortho by way of reimbursement its reasonable documented out-of-pocket costs, fees and expenses incurred in connection with its investigation, consideration, documentation, diligence and negotiations of the BCA and the transactions contemplated thereby, including all reasonable fees and expenses of Ortho’s and its subsidiaries’ respective representatives and financing sources.

In the event the Quidel Termination Payment is payable by Quidel to Ortho after the time Quidel pays any expense reimbursement to Ortho in accordance with the terms of the BCA, the amount of the Quidel Termination Payment payable by Quidel to Ortho will be reduced by the amount of such expense reimbursement actually paid to Ortho.

294

Ortho must pay Quidel a termination fee of $46,880,426.11 (the “Ortho Termination Payment”) if:

| • |  | the BCA is terminated by Quidel, as a result of an Ortho Change in Recommendation;

| • |  | the BCA is terminated by either Quidel or Ortho if (i) the Combinations are not consummated by the Termination Date or (ii) the Ortho Requisite Vote has not been obtained at the Ortho Shareholder Meetings or the Ortho Scheme is not sanctioned and the Ortho Scheme Order is not issued by the Court and, at the time of such termination, Quidel had a right to terminate as a result of an Ortho Change in Recommendation;

| • |  | (a) an Acquisition Proposal for Ortho shall have been publicly announced or made publicly known or otherwise communicated or made known to Ortho management or the Ortho board of directors (or any third party shall have publicly announced, communicated or made known a bona fide intention, whether or not conditional, to make a proposal with respect to an Acquisition Proposal) and not withdrawn prior to termination or such vote to adopt the BCA, as applicable, at any time after the date of the BCA and (b) the BCA is subsequently terminated by Quidel as a result of Ortho’s breach of the BCA or is terminated by either Quidel or Ortho because (i) the Combinations are not consummated by the Termination Date or (ii) the Ortho Requisite Vote has not been obtained at the Ortho Shareholder Meetings or the Ortho Scheme is not sanctioned and the Ortho Scheme Order is not issued by the Court and, at the time of such termination, Quidel had a right to terminate the BCA as a result of a failure by Ortho to perform any of its covenants or agreements contained in the BCA;

| • |  | the BCA is terminated by Ortho in connection with an Ortho All Cash Superior Proposal, subject to certain additional conditions; or

| • |  | (a) an Acquisition Proposal for Ortho has been publicly announced or made publicly known or otherwise communicated or made known to Ortho management or the Ortho board of directors (or any third party shall have publicly announced, communicated or made known a bona fide intention, whether or not conditional, to make a proposal with respect to an Acquisition Proposal) and not withdrawn prior to termination or such vote to adopt the BCA, as applicable, at any time after the date of the BCA, (b) the BCA is subsequently terminated by Quidel or Ortho because (i) the Combinations are not consummated by the Termination Date or (ii) the Ortho Requisite Vote has not been obtained at the Ortho Shareholder Meetings or the Ortho Scheme is not sanctioned and the Ortho Scheme Order is not issued by the Court, and (c) within nine months of such termination, Ortho or any of its subsidiaries executes an acquisition agreement with respect to, or consummates, or approves or recommends to the Ortho shareholders to accept, any Acquisition Proposal (provided that, for purposes of this clause (c), the term “Acquisition Proposal” is defined as in the section entitled “The Business Combination Agreement—Acquisition Proposals” of this joint proxy statement/prospectus, except that each reference to “15% or more” in the definition of “Acquisition Proposal” and “Major Subsidiary” shall be deemed to be a reference to “50% or more”).

In the event that the BCA is terminated because the Ortho Requisite Vote has not been obtained at the Ortho Shareholder Meetings or the Ortho Scheme is not sanctioned and the Ortho Scheme Order is not issued by the Court, and the Ortho Termination Payment is not otherwise payable, then Ortho shall pay, or cause to be paid, to Quidel by way of reimbursement its reasonable documented out-of-pocket costs, fees and expenses incurred in connection with its investigation, consideration, documentation, diligence and negotiations of the BCA and the transactions contemplated thereby, including all reasonable fees and expenses of Quidel’s and its subsidiaries’ respective representatives and financing sources.

In the event the Ortho Termination Payment is payable by Ortho to Quidel after the time Ortho pays any expense reimbursement to Quidel in accordance with the terms of the BCA, the amount of the Ortho Termination Payment payable by Ortho to Quidel will be reduced by the amount of such expense reimbursement actually paid to Quidel.

Specific Performance

Quidel and Ortho have agreed that Quidel and Ortho will be entitled to an injunction, specific performance and other equitable relief to prevent breaches or threatened breaches of the BCA by the other parties and to enforce specifically the terms and provisions of the BCA, in addition to any other remedy to which they are entitled. However, a party will not be entitled to both specific performance and the payment of any termination fee described above under “Expenses and Termination Fees.”

295

STOCKHOLDERS AGREEMENT / DEED OF IRREVOCABLE UNDERTAKING

Stockholders Agreement

In connection with execution of the BCA, Ortho, Quidel, Topco and the Carlyle Stockholder entered into a stockholders agreement (the “Stockholders Agreement”) which will replace the stockholders agreement currently in effect between Ortho and the Carlyle Stockholder, which provides for, among other things, certain registration and information rights (the “Current Ortho Stockholders Agreement”). A copy of the Stockholders Agreement is attached to this joint proxy statement/prospectus as Annex B and is incorporated by reference into this joint proxy statement/prospectus. The Stockholders Agreement provides, among other things, that:

| • |  | Board Representation. So long as the Carlyle Stockholder holds at least 12% of the outstanding Topco Shares, then the Carlyle Stockholder may nominate two individuals to the Topco board of directors. If the Carlyle Stockholder holds at least 5% but less than 12% of the outstanding Topco Shares, then it may nominate one individual to the Topco board of directors. The Carlyle Stockholder is not entitled to any nomination rights with respect to the Topco board of directors if it holds less than 5% of the outstanding Topco Shares.

| • |  | Registration Rights. The Stockholders Agreement grants the Carlyle Stockholder registration rights, including demand rights and piggyback rights, each subject to certain limitations. The Carlyle Stockholder’s demand rights (excluding rights with respect to “shelf” registrations) expire in the event that the Carlyle Stockholder owns less than 5% of the outstanding Topco Shares, and its other registration rights expire on a holder-by-holder basis when a given Carlyle Stockholder owns less than 1% of the outstanding Topco Shares, in each case, only if such Carlyle Stockholder can sell its Topco Shares without volume or manner of sale restrictions under Rule 144 under the Securities Act.

| • |  | Corporate Opportunity Waiver. The Stockholders Agreement includes a customary corporate opportunity waiver provision, duly adopted by the Topco board of directors.

| • |  | Information Rights. The Stockholders Agreement provides the Carlyle Stockholder with (a) customary rights to financial information so long as the Carlyle Stockholder holds 5% or more of the outstanding Topco Shares, and (b) additional access to information and Topco management so long as the Carlyle Stockholder holds 10% or more of the outstanding Topco Shares.

Current Ortho Stockholders Agreement

The Current Ortho Stockholders Agreement provides for registration and information rights that are generally similar to those that will exist under the Stockholders Agreement. However, there are certain changes in the Stockholders Agreement including: (i) an increase to the minimum transaction size for non-shelf demand offerings and shelf takedowns from $50 million to $250 million, (ii) termination of registration rights when the Carlyle Stockholder (with any affiliates or transferees) owns less than 5% of the outstanding Topco Shares or if it is able to sell Topco Shares under Rule 144 of the Securities Act, without volume or manner of sale restrictions, (iii) removal of the right to receive an annual budget and (iv) termination of access rights when the Carlyle Stockholder (with any affiliates or transferees) owns less than 10% of the outstanding Topco Shares. The Stockholders Agreement also includes director appointment rights, which are currently addressed in the articles of association of Ortho.

Irrevocable Undertaking

In connection with its entry into the BCA, Ortho and Quidel received from the Carlyle Stockholder a deed of irrevocable undertaking (“Irrevocable Undertaking”) to vote or procure votes in favor of the Ortho Scheme of arrangement at the Ortho Court Meeting and the resolution to be proposed at the Ortho General Meeting, in respect of 118,106,000 Ortho Shares beneficially owned by the Carlyle Stockholder, representing approximately 49.79% of the Ortho Shares. The Irrevocable Undertaking, which terminates if the BCA is terminated, requires the Carlyle Stockholder to vote their Ortho Shares in favor of and accept the Combinations, and, subject to certain exceptions, prohibits the applicable shareholder from dealing in (including transferring or encumbering) its Ortho Shares. A copy of the Irrevocable Undertaking is attached to this joint proxy statement/prospectus as Annex C and is incorporated by reference into this joint proxy statement/prospectus.

296

INTERESTS OF CERTAIN PERSONS IN THE COMBINATIONS (QUIDEL)

Quidel’s executive officers and directors have interests in the Combinations that are different from, or in addition to, the interests of Quidel stockholders generally. The Quidel board of directors was aware of these potentially differing interests and considered them, among other matters, in reaching its decision to adopt the BCA, approve the Combinations and to recommend that you vote in favor of the Merger Proposal.

See the sections entitled “The Combinations—Background of the Combinations” and “The Combinations—Quidel Reasons for the Combinations and Recommendation of the Quidel Board of Directors” of this joint proxy statement/prospectus. Quidel stockholders should take these interests into account in deciding whether to vote “FOR” the Merger Proposal. These interests are described in more detail below, and certain of them are quantified in the narrative and the table included under the section entitled “—Golden Parachute Compensation.”

These interests may include, but are not limited to:

| • |  | the treatment in the Combinations of equity awards held by Quidel directors and executive officers;

| • |  | success bonus awards payable upon the consummation of the Combinations, the amounts of which are described in the section entitled “—Success Bonuses;”

| • |  | integration/retention cash bonus awards, 25% of which will be payable upon the consummation of the Combinations and the remaining 75% of which will be payable on the first anniversary of the consummation of the Combinations, the amounts of which are described in the section entitled “—Integration/Retention Bonuses—Cash”;

| • |  | integration/retention equity bonus awards, which were granted in the form of Quidel RSUs and will vest with respect to 50% of the award on the second anniversary of the grant date and the remaining 50% in equal annual installments (25% per year) thereafter, which are described in the section entitled “—Integration/Retention Bonuses—Equity”;

| • |  | the continued employment of certain executive officers of Quidel, as described in the section entitled “Topco Positions;”

| • |  | the continued positions of certain directors of Quidel as directors on the board of directors of Topco, as described in the section entitled “Topco Positions;” and

| • |  | severance payments payable under existing employment and severance arrangements or arrangements that may be entered into in connection with the Combinations.

Treatment of Quidel Equity Awards

The Combinations will not constitute a change in control under the Quidel Stock Plans. Nonetheless, pursuant to the terms of the BCA, each award of outstanding Quidel Stock Options, Quidel RSUs and Quidel PSUs will be treated as follows:

Stock Options

At the Quidel Effective Time, each outstanding Quidel Stock Option granted under a Quidel Stock Plan, whether vested or unvested, will automatically, without any action on the part of the holder thereof, cease to represent an option to acquire Quidel Shares and be converted into a Topco Stock Option on the same terms and conditions (including applicable vesting conditions) applicable to such Quidel Stock Option under the applicable Quidel Stock Plan and award agreement in effect immediately prior to the Quidel Effective Time, except as adjusted by the BCA. The number of Topco Shares subject to each such Topco Stock Option will be equal to the number of Quidel Shares subject to such Quidel Stock Option immediately prior to the Quidel Effective Time, and each such Topco Stock Option will have an exercise price per share equal to the exercise price per Quidel Share of such Quidel Stock Option immediately prior to the Quidel Effective Time.

Restricted Stock Units

At the Quidel Effective Time, each outstanding Quidel RSU granted under a Quidel Stock Plan will automatically, without any action on the part of the holder thereof, be converted into a Topco RSU on the same terms and conditions (including

297

applicable vesting conditions) applicable to such Quidel RSU under the applicable Quidel Stock Plan and award agreement in effect immediately prior to the Quidel Effective Time. The number of Topco Shares covered by each such Topco RSU will be equal to the number of Quidel Shares subject to such Quidel RSU immediately prior to the Quidel Effective Time.

Performance Restricted Stock Units

At the Quidel Effective Time, each outstanding Quidel PSU granted under a Quidel Stock Plan will automatically, without any action on the part of the holder thereof, be converted into a Topco PSU on the same terms and conditions (including applicable vesting conditions) applicable to such Quidel PSU under the applicable Quidel Stock Plan and award agreement in effect immediately prior to the Quidel Effective Time. The number of Topco Shares covered by each such Topco PSU will be equal to the number of Quidel Shares subject to such Quidel PSU immediately prior to the Quidel Effective Time. The Quidel board of directors, or an applicable committee thereof, may, prior to the Ortho Effective Time make such equitable adjustments, if any, to the applicable performance goals or conditions relating to such Quidel PSU, as the Quidel board of directors may determine to be necessary or appropriate as a result of the consummation of the Combinations, which equitable adjustments shall take effect upon and be subject to the consummation of the Combinations and, in each case, subject to and in accordance with the terms and conditions of the Quidel Stock Plans and Quidel PSU.

Success Bonuses

In connection with the Combinations, Quidel approved the grant of success bonus awards to certain employees and executive officers (the “Success Bonuses”). The Success Bonuses are being implemented to reward key talent and will be paid out to recipients upon the consummation of the Combinations. The Success Bonuses will be grossed up for taxes. The following executives are entitled to receive a Success Bonus in the following amounts: Douglas Bryant: $875,500; Randall Steward: $499,550; Robert Bujarski: $525,000; and Michelle Hodges: $450,000.

Integration/Retention Bonuses

Cash

Quidel has approved the grant of integration/retention cash bonuses to certain employees and executive officers (the “Cash Retention Bonuses”). The Cash Retention Bonuses are being implemented to retain key talent following the consummation of the Combinations. The first 25% of the Cash Retention Bonus will become payable upon the closing of the Combinations, and the remaining 75% upon the first anniversary thereof, subject to the recipient’s continued employment through such dates. If a recipient’s employment is terminated by Quidel without cause prior to the full payment of the Cash Retention Bonus, then the unpaid portion of the Cash Retention Bonus will be paid by the 60th day following such termination, subject to the recipient’s execution, and non-revocation, of a general release of claims in favor of Quidel. Cash Retention Bonuses have been awarded to the following executives in the following amounts: Douglas Bryant: $717,500; Randall Steward: $349,685; Robert Bujarski: $420,000; Michelle Hodges: $315,000; and Dr. Werner Kroll: $385,000.

Equity

Quidel has also approved the grant of integration/retention equity bonuses to certain employees and executive officers (the “Equity Retention Bonuses”), which have been approved to retain key talent following the consummation of the Combinations. The Equity Retention Bonuses were granted in the form of Quidel RSUs and will vest with respect to 50% of the award on the second anniversary of the grant date and the remaining 50% in equal annual installments (or 25% per year) thereafter; provided, however, that (x) the vesting of the Quidel RSUs is contingent upon the consummation of the Combinations having occurred prior to the applicable vesting date, and (y) the Quidel RSUs will be automatically forfeited in the event the BCA is terminated in accordance with its terms. If a recipient’s employment is terminated by Quidel without cause prior to the full vesting of the Equity Retention Bonus, then the unvested portion of the Equity Retention Bonus will vest immediately upon such termination of employment, subject to the recipient’s execution, and non-revocation, of a general release of claims in favor of Quidel. Equity Retention Bonuses have been awarded to the following executives in the following amounts: Douglas Bryant: target value of $2,500,000; Robert Bujarski: target value of $1,400,000; Michelle Hodges: target value of $750,000; and Dr. Werner Kroll: target value of $750,000.

Post-Combinations Compensation and Benefit Arrangements

Pursuant to the BCA, employees of Quidel and its subsidiaries at the Quidel Effective Time who continue to remain employed with Quidel or its subsidiaries (the “Quidel Continuing Employees”) shall, during the period commencing at the Quidel Effective Time and ending on the one-year anniversary thereof, be provided with base salary or base wage, severance benefit protections, and pension and welfare benefits that are no less favorable, in the aggregate, than those provided to such Quidel Continuing Employees immediately prior to the Quidel Effective Time.

In addition, executive officers and directors who are retained to provide services to Quidel following the consummation of the Combinations may enter into new individualized compensation arrangements. As of the date of this joint proxy statement/prospectus, no compensation arrangements have been established.

Executive Severance Arrangements

Each of Douglas Bryant, Randall Steward and Robert Bujarski are party to agreements with Quidel which provide for severance benefits in the event of a qualifying termination of employment.

Messrs. Bryant, Steward and Bujarski, Ms. Hodges and Dr. Kroll are party to change in control agreements with Quidel, though the Combinations do not constitute a “change in control” within the meaning of such agreements, and therefore no compensation or benefits are payable thereunder as a result of the Combinations.

Douglas Bryant

If Mr. Bryant’s employment with Quidel is terminated without “cause” (as defined in his employment agreement) or he terminates his employment for “good reason” (as defined in his employment agreement) and thereafter delivers and does not revoke a general release, he is entitled to a severance payment equal to 18 months of his then-current base salary and payment of health insurance premiums for a period of 18 months following termination.

“Cause” is generally defined in Mr. Bryant’s employment agreement as: (i) fraud; (ii) personal dishonesty involving money or property of Quidel or that results in material harm to Quidel; (iii) Mr. Bryant’s willful misconduct that is materially injurious to Quidel; (iv) a serious breach of a fiduciary duty to Quidel involving personal profit; (v) Mr. Bryant’s conviction for a felony (including a guilty or nolo contendere plea), excluding traffic offenses; (vi) Mr. Bryant’s willful and continued neglect of duties (other than any such failure resulting from his incapacity because of physical or mental illness); or (vii) Mr. Bryant’s material breach of certain provisions of his employment agreement.

“Good reason” is generally defined in Mr. Bryant’s employment agreement as: (i) the failure to elect and continue Mr. Bryant as Chief Executive Officer of Quidel, or if the scope of Mr. Bryant’s duties and responsibilities are in the aggregate materially reduced; (ii) a requirement by Quidel or the Quidel board of directors that Mr. Bryant, without his prior consent, be relocated to a Quidel office more than 50 miles from the current executive offices of Quidel, or Quidel requires Mr. Bryant to be based anywhere other than the principal executive offices of Quidel; (iii) any material reduction in Mr. Bryant’s base salary, provided that Quidel does not pay Mr. Bryant an appropriate cash amount to reimburse him for the base salary reduction; or (iv) a material breach by Quidel of any of the terms of the employment agreement.

Randall Steward

Quidel and Mr. Steward have entered into an individual retirement program, which outlines the terms of Mr. Steward’s compensation through the date on which his employment with Quidel terminates. The program previously contemplated that Mr. Steward’s employment would terminate on March 31, 2022, though in connection with the anticipated transactions contemplated by the BCA the parties determined it to be in their mutual interest to amend Mr. Steward’s individual retirement program to provide that he will remain employed until the earlier of (i) the consummation of the Combinations or (ii) the termination of the BCA. Upon the termination of Mr. Steward’s employment, the parties will enter into a “special advisor transition agreement.” This agreement will have an initial term of one year from the effective date thereof, which may be extended until March 31, 2024. During the term of the “special advisor transition agreement,” Mr. Steward shall be entitled to receive $300,000 per year in compensation, which shall be paid in equal installments in accordance with Quidel’s regular payroll.

299

Robert Bujarski

Mr. Bujarski is party to an employment agreement with Quidel which provides that if his employment is terminated by Quidel without cause, he is entitled to a severance payment equal to six months of his annual then-current base salary. Cause is not defined in Mr. Bujarski’s employment agreement.

Golden Parachute Compensation

This section sets forth the information required by Item 402(t) of Regulation S-K regarding the compensation of each of Quidel’s five current NEOs that is based on or otherwise relates to the Combinations and that will or may become payable to the NEOs at the Quidel Effective Time or upon a qualifying termination of employment on or following the Quidel Effective Time. This compensation is referred to as “golden parachute” compensation by the applicable SEC disclosure rules, and in this section we use such term to describe the Combinations-related compensation payable to Quidel’s NEOs.

The amounts shown in the table below are estimates based on multiple assumptions that may or may not actually occur or be accurate on the relevant date, including the assumptions described below and in the footnotes to the table, and do not reflect certain compensation actions that may occur before consummation of the Combinations. For purposes of calculating such amounts, the following assumptions were used:

| • |  | The Quidel Effective Time is April 30, 2022, which is the assumed date of the closing of the Quidel Merger solely for purposes of this golden parachute compensation disclosure;

| • |  | Each NEO experienced a qualifying termination (i.e., a termination without “cause” or for “good reason,” as defined in the relevant agreements), immediately following the assumed Quidel Effective Time ; and

| • |  | The per share value of Quidel Shares is $103.36, which is the closing price for Quidel Shares on January 31, 2022, the grant date of the Equity Retention Bonuses.

As a result of the foregoing assumptions, the actual amounts, if any, to be received by a NEO may materially differ from the amounts set forth below.

Name |  | Cash ($)(1) |  | Equity ($)(3) |  | Perquisites / Benefits ($)(4) |  | Tax Reimbursement ($)(5) |  |  | Other ($)(6) |  | Total Value ($)
Douglas C. Bryant |  | 1,537,500 |  | 2,499,968 |  | 41,364 |  |  | 1,736,414 |  |  | 1,593,000 |  | 7,408,246
Randall J. Steward |  | 300,000(2) |  | — |  | — |  |  | 990,777 |  |  | 849,235 |  | 2,140,012
Robert J. Bujarski |  | 300,000 |  | 1,400,011 |  | — |  |  | 1,011,566 |  |  | 945,000 |  | 3,656,577
Michelle A. Hodges |  | — |  | 750,283 |  | — |  |  | 687,863 |  |  | 765,000 |  | 2,203,146
Werner Kroll, Ph.D. |  | — |  | 750,283 |  | — |  |  | — |  |  | 385,000 |  | 1,135,283

(1) | Amounts shown reflect the cash severance payable to each NEO upon a qualifying termination of employment. Mr. Bryant is entitled to receive severance in the event of a termination of employment without cause or for good reason, and Mr. Bujarski is entitled to severance upon a termination of employment without cause.

(2) | Upon the termination of Mr. Steward’s employment, Mr. Steward will enter into a special advisor transaction agreement, which provides for base compensation of $300,000 per year for the duration of such agreement, which shall be paid in equal installments in accordance with Quidel’s regular payroll.

(3) | The amounts in this column represent the value of unvested equity awards held by each NEO that would be accelerated upon a qualifying termination of employment.

(4) | For Mr. Bryant, represents the value of continued health insurance benefits pursuant to his employment agreement, which would be payable only if Mr. Bryant’s employment was terminated without cause or he resigned for good reason.

(5) | The amounts in this column reflect the tax reimbursement payable to each NEO who is entitled to a success bonus.

(6) | Includes the value of the Success Bonus and Cash Retention Bonus payable to each NEO. The Success Bonus is payable upon the consummation of the Combinations, subject to continued employment through such date. Messrs. Bryant, Steward and Bujarski and Ms. Hodges are eligible for Success Bonuses equal to $875,500, $499,550, $525,000, and $450,000, respectively. The Cash Retention Bonus is payable 25% upon the consummation of the Combinations, and the remaining 75% upon the first anniversary thereof; provided that the Cash Retention Bonus will become payable upon a termination without cause. Messrs. Bryant, Steward and Bujarski, Ms. Hodges and Dr. Kroll are eligible for Cash Retention Bonuses equal to $717,500, $349,685, $420,000, $315,000 and $385,000.

300

Topco Positions

Effective as of the Ortho Effective Time, the Topco board of directors will consist of 12 members, comprised of (i) eight members designated by Quidel, expected to consist of Messrs. Bryant, Buechler, Michael, Strobeck, Widder and Wilkins and Mses. Polan and Rhoads, each of whom, other than Mr. Bryant, qualifies as an “independent director” under applicable rules of Nasdaq and (ii) four members designated by Ortho, at least two of whom will qualify as an “independent director” under applicable rules of Nasdaq. Each of the members of the Topco board of directors designated by Ortho shall be reasonably acceptable to the nominating and corporate governance committee of the current Quidel board of directors.

Douglas Bryant, current President and Chief Executive Officer of Quidel, will serve as the Chair of the Topco board of directors and as the Chief Executive Officer of Topco.

Additionally, Robert Bujarski, current Chief Operating Officer of Quidel, will serve as the President and Chief Operating Officer of Topco.

Insurance and Indemnification of Directors and Executive Officers

The terms of the BCA provide for certain post-closing covenants related to insurance and indemnification of directors and executive officers. For a description of such covenants, see the section entitled “The Business Combination Agreement—Indemnification and Insurance” of this joint proxy statement/prospectus.

301

INTERESTS OF CERTAIN PERSONS IN THE COMBINATIONS (ORTHO)

Ortho’s executive officers and directors have interests in the Ortho Scheme that are different from, or in addition to, the interests of Ortho shareholders generally. The Ortho board of directors was aware of these potentially differing interests and considered them, among other matters, in reaching its decision to adopt the BCA, approve the Combinations and to recommend that you vote in favor of all proposals to be approved at the Ortho Shareholder Meetings.

See the sections entitled “The Combinations—Background of the Combinations” and “The Combinations—Ortho Reasons for the Combinations and Recommendation of the Ortho Board of Directors” of this joint proxy statement/prospectus. Ortho shareholders should take these interests into account in deciding whether to vote “FOR” the Ortho Scheme Proposal. These interests are described in more detail below, and certain of them are quantified in the narrative and the table included under the section entitled “Golden Parachute Compensation.”

These interests may include, but are not limited to:

| • |  | the continued engagement and/or employment, as applicable, of certain board members and executive officers of Ortho, as described in the section entitled “Topco Positions”;

| • |  | the continued positions of certain directors of Ortho as directors on the board of directors of Topco, as described below in the section entitled “Topco Positions”;

| • |  | the treatment in the Combinations of equity awards and stock options held by Ortho directors and executive officers;

| • |  | retention bonus awards, 40% of which will be payable at the closing of the Combinations and the remaining 60% of which will be payable on the first anniversary of the closing of the Combinations, the amounts of which are described in the section entitled “Retention Bonuses”;

| • |  | transaction bonuses payable upon the closing of the Combinations, the amounts of which are described in the section entitled “Transaction Bonuses”; and

| • |  | severance payments payable under existing employment and severance arrangements or arrangements that may be entered into in connection with the Combinations.

In respect of the Ortho directors and named executive officers, the Combinations shall impact their board service and results in equity and cash based awards as summarized below:

Compensation Payable as a Result of the Combinations

All directors and executive officers of Ortho who are Ortho shareholders will receive Ortho Scheme Consideration in respect of their Ortho Shares, calculated in the same manner as the Ortho Scheme Consideration is calculated for all other Ortho shareholders. As described below in the section entitled “Interests of Certain Persons in the Combinations (Ortho)—Executive Severance Agreements” and as summarized in the table entitled “Interests of Certain Persons in the Combinations (Ortho)—Golden Parachute Compensation” Messrs. Smith, Iskra, Busky, Palaniappan and Schlesinger, as well as certain other executive officers who are Ortho shareholders, are eligible for severance payments under certain circumstances. The severance arrangements are contractual and were established prior to signing of the BCA and not in anticipation of the Combinations. As described below in the sections entitled “Interests of Certain Persons in the Combinations (Ortho)—Retention Bonuses” and “Interests of Certain Persons in the Combinations (Ortho)—Transaction Bonuses” and as summarized in the table entitled “Interests of Certain Persons in the Combinations (Ortho)—Golden Parachute Compensation,” Ortho has approved retention bonuses for Messrs. Busky, Iskra, Palaniappan and Schlesinger and transaction bonuses for Messrs. Smith, Busky, Iskra and Schlesinger. The retention bonuses and transaction bonuses were approved by the compensation committee of the Ortho board of directors in connection with the Combinations and are consistent with typical market practice in the United States for similarly situated executives in a transaction similar to the Combinations.

Compensation following the Combinations

The BCA contemplates that Mr. Busky will serve as the Chief Financial Officer of Topco, and Mr. Iskra will serve as the Chief Commercial Officer of Topco, in each case after closing the Combinations. Compensation for Messrs. Busky and Iskra in such roles has not yet been determined. Quidel and Ortho have not yet identified which other executives of Ortho will

302

serve in senior management positions of Topco, although the BCA provides that, for 12 months following the Ortho Effective Time, each Ortho Continuing Employee will receive base salary or wages, severance benefit protections and pension and welfare benefits that are no less favorable, in the aggregate, than those provided to such Ortho Continuing Employees immediately prior to the Ortho Effective Time. Four members of the post-closing board of directors of Topco will be appointed by Ortho, but Ortho and Quidel have not yet determined what compensation, if any, will be paid to such individuals in consideration for serving as directors.

Treatment of Ortho Equity Awards

See the section below entitled “Interests of Certain Persons in the Combinations (Ortho)—Treatment of Ortho Equity Awards” for a description of the treatment of Ortho Equity Awards held by members of the board of directors of Ortho and management of Ortho after closing of the Combinations. In general, directors and members of management will receive the same treatment as holders of other Ortho Equity Awards, provided that certain of Mr. Smith’s Ortho Equity Awards contain different vesting terms than apply to other holders of Ortho Equity Awards.

Shareholding by Directors and Officers

See the section below entitled “Security Ownership of Certain Ortho Beneficial Owners and Management” for a summary of the shareholding of members of the board of directors of Ortho and the named executive officers of Ortho.

Compensation Actions in Connection with the Combinations

In connection with the Combinations, Ortho retained the discretion to take action to: (i) deem a “Liquidity Event” (as defined under the Ortho equity awards) to have occurred with respect to Ortho’s outstanding equity awards upon any of (A) the completion of the Combinations, (B) an involuntary (“without cause”) or constructive (“good reason”) termination of employment upon or following the completion of the Combinations, or (C) the completion of a specified period of service after the closing of the Combinations, and the deemed occurrence of a Liquidity Event may result in vesting of certain Ortho equity awards; (ii) modify vesting and related provisions of outstanding Ortho equity awards that, without modification, would result in forfeitures in connection with the Combinations; (iii) provide that outstanding equity awards held by Ortho’s non-employee directors who will not serve on the Topco board of directors following the completion of the Combinations will vest upon the closing of the Combinations; (iv) provide that Ortho’s outstanding equity awards will vest as a result of an involuntary (“without cause”) or constructive (“good reason”) termination of employment upon or following the completion of the Combinations; (v) provide for awards containing “Liquidity Event” vesting provisions to vest upon the earlier of the time specified in the applicable award agreement or upon a specified date that is not less than six months following the completion of the Combinations, (vi) enter into change in control severance agreements with officers and employees on terms and conditions no more favorable than those in place for comparable Quidel employees and (vii) provide for certain incremental cash payment programs for succession and/or retention purposes, payable upon or after completion of the Combinations.

Subsequent to the execution of the BCA, as detailed below, Ortho has approved certain retention and transaction bonus arrangement for Ortho’s executive officers and has determined that all of Ortho’s outstanding and unvested stock options, restricted stock and restricted stock units will vest on a “double trigger” basis in the event the holder’s service is terminated without cause in connection with the Combinations. In addition, prior to the closing of the Combinations, Ortho may make additional changes to compensation arrangements for Ortho’s officers and board members, as permitted under the BCA, although no determinations have yet been made in regard to the foregoing.

Treatment of Ortho Equity Awards

Stock Options

As of January 20, 2022, there were 12,723,304 outstanding Ortho Stock Options. If at the Ortho Effective Time there are outstanding Ortho Stock Options, then each such Ortho Stock Option will be converted into (i) a Topco Stock Option on the same terms and conditions as were applicable to such Ortho Stock Option immediately prior to the Ortho Effective Time, (ii) with respect to the portion of the Ortho Stock Option that is vested at the Ortho Effective Time, a right to receive payment, in cash, upon the closing of the Combinations, equal to the Cash Portion in respect of the Ortho Shares that are subject to the vested portion of the Ortho Stock Option, and (iii) with respect to the portion of the Ortho Stock Options that

303

are unvested at the Ortho Effective Time, a right to receive payment, in cash, equal to the Cash Portion in respect of the Ortho Shares that are subject to the unvested portion of the Ortho Stock Option, payable through the payroll system or payroll provider of Topco or its affiliate and subject to applicable withholding, as and when the corresponding portion of the Ortho Stock Option would have vested. The number of Topco Shares subject to each such Topco Stock Option shall be equal to the product (rounded down to the nearest whole number) of (x) the number of Ortho Shares subject to such Ortho Stock Option immediately prior to the Ortho Effective Time and (y) the Ortho Exchange Ratio, and such Topco Stock Option shall have an exercise price per share (rounded up to the nearest whole cent) equal to (A) the exercise price per Ortho Share of such option immediately prior to the Ortho Effective Time divided by (B) the Ortho Exchange Ratio; provided, however, that the exercise price and the number of Topco Shares purchasable pursuant to such Topco Stock Option will be determined in a manner consistent with the requirements of Section 409A of the Code, without reducing the total value of consideration provided to the holders of Ortho Stock Options hereunder; provided, further, that in the case of any Ortho Stock Option to which Section 422 of the Code applies, the exercise price and the number of Topco Shares purchasable pursuant to such Ortho Stock Option will be determined in accordance with the foregoing, subject to such adjustments as are necessary in order to satisfy the requirements of Section 424(a) of the Code without reducing the total value of consideration provided to the holders of Ortho Stock Options hereunder.

In the event that the service of a holder of Ortho Stock Options is terminated without cause in connection with or following the closing of the Combinations, such holder’s Ortho Stock Options will become fully vested. In addition, all unvested Ortho Stock options held by Mr. Smith as of the Closing will become fully vested.

Restricted Stock Units and Restricted Stock

As of January 20, 2022, there were 166,250 Ortho restricted stock unit awards and 388,724 unvested shares of Ortho restricted stock outstanding. Each award of restricted stock, restricted stock units or other similar rights or awards granted under an Ortho Stock Plan and relating to Ortho Shares (any such award, an “Ortho Equity Right” and such awards together with the Ortho Stock Options, the “Ortho Stock Awards”) that is outstanding immediately prior to the Ortho Effective Time will automatically be converted, at the Ortho Effective Time, into (i) an award of restricted stock, restricted stock units or other similar rights or awards, as applicable, relating to Topco Shares (a “Topco Equity Right” and, together with the Topco Stock Options, “Topco Stock Awards”) of the same type and on the same terms and conditions as were applicable to the corresponding Ortho Equity Right, and (ii) a right to receive payment, in cash, equal to the Cash Portion in respect of the Ortho Shares that are subject to the Ortho Equity Right, payable through the payroll system or payroll provider of Topco or its affiliate and subject to applicable withholding, as and when the corresponding Ortho Equity Right vests. The number of Topco Shares covered by each such Topco Equity Right will be equal to the product (rounded to the nearest whole number) of (x) the number of Ortho Shares subject to the Ortho Equity Right immediately prior to the Ortho Effective Time and (y) the Ortho Exchange Ratio.

In the event that the service of a holder of Ortho restricted stock or restricted stock units is terminated without cause in connection with or following the closing of the Combinations, such holder’s restricted stock or restricted stock units will become fully vested. In addition, a portion of the restricted stock held by Mr. Smith will vest upon the closing and a portion will vest over an expected time period of 12 months based on continued service following the closing (with acceleration in the event of being removed from the board) pursuant to terms to be agreed between Mr. Smith and Ortho’s compensation committee.

304

The following table sets forth the number of Ortho Stock Options and Ortho Equity Rights that were awarded to and held by Ortho executive officers and non-employee directors as of January 20, 2022 under an Ortho Stock Plan and the value of these awards in the Combinations, assuming a per share value of Ortho’s ordinary shares equal to $20.79, which is the average of the closing price of Ortho’s ordinary shares over the first five trading days following the announcement of the Combinations. The foregoing equity awards will be treated in the same manner as outstanding equity awards generally and described above.

Ortho previously entered into an employment agreement with Mr. Smith, pursuant to which he is eligible for severance payments and benefits in the event of a qualifying termination of employment. Specifically, if Mr. Smith’s employment is terminated without “cause” or he resigns for “good reason,” subject to his execution and non-revocation of a release in favor of Ortho, he is entitled to receive (i) an amount equal to one times the sum of his then-current base salary and target annual bonus, payable in installments for 12 months following Mr. Smith’s termination of employment, and (ii) payments lasting for up to 12 months equal to the amounts Mr. Smith would be required to pay for continued coverage under Ortho’s group medical and dental benefit plans.

For purposes of Mr. Smith’s employment agreement:

| • |  | “cause” means, subject to notice and cure rights, Mr. Smith’s (i) failure to (A) substantially perform his duties with Ortho (other than any such failure resulting from disability) or (B) comply with, in a material respect, any of Ortho’s policies, in each case that results in material damage to Ortho’s property, business or reputation, (ii) repeated failure in a material respect to carry out or comply with any lawful and reasonable directive of the Ortho board of directors within the scope of his duties, (iii) breach of a material provision of his employment agreement that results in material damage to Ortho’s property, business or reputation, (iv) conviction, plea of no contest, plea of nolo contendere or imposition of unadjudicated probation for any felony or crime involving moral turpitude, (v) unlawful use (including being under the influence) or possession of illegal drugs on Ortho’s (or any of its affiliate’s) premises or while performing his duties and responsibilities under the employment agreement or (vi) commission of an act of fraud, embezzlement, misappropriation, or breach of fiduciary duty against Ortho or any of its affiliates; and

305

| • |  | “good reason” means, subject to notice and cure rights, Mr. Smith’s resignation following any of the following without his prior written approval: (i) a decrease in his annual base salary or target bonus, other than a reduction in annual base salary of less than 10% that is implemented in connection with a contemporaneous and proportional reduction in annual base salaries affecting all other senior executives of Ortho, (ii) a material decrease in his authority or areas of responsibility as are commensurate with his title or position (other than in connection with a corporate transaction where he continues to hold his position with respect to Ortho’s business, substantially as such business exists prior to the date of consummation of such corporate transaction, but does not hold such position with respect to the successor corporation) or (iii) Ortho’s material breach of any material agreement with him.

Michael Iskra

Pursuant to a severance letter agreement with Ortho, if Mr. Iskra’s employment is terminated without cause, he will be entitled to severance payments equal to six months of his annual base salary, 50% of his target bonus and subsidized health benefit coverage during the six-month period following his termination.

Joseph Busky

Pursuant to a severance letter agreement with Ortho, if Mr. Busky’s employment is terminated without cause, he will be entitled to severance payments equal to six months of his annual base salary.

Chockalingam Palaniappan

Pursuant to a severance letter agreement with Ortho, if Dr. Palaniappan’s employment is terminated without cause, he will be entitled to severance payments equal to 12 months of his annual base salary.

Michael A. Schlesinger

Ortho entered into an employment agreement with Mr. Schlesinger, pursuant to which he is eligible for severance payments and benefits in the event of a qualifying termination of employment. If Ortho terminates Mr. Schlesinger’s employment without “cause” or he resigns for “good reason,” subject to his execution and non-revocation of a release in favor of Ortho, he is entitled to receive (i) an amount equal to 1.25 times the sum of his then-current annual base salary and target annual bonus, payable in installments for 15 months following Mr. Schlesinger’s termination of employment, and (ii) payments lasting for up to 15 months equal to the amounts Mr. Schlesinger would be required to pay for continued coverage under Ortho’s group medical and dental benefit plans. For purposes of Mr. Schlesinger’s employment agreement, “cause” and “good reason” have substantially the same meaning as in Mr. Smith’s employment agreement.

Severance Pay Plan

Executive officers are eligible for severance benefits under the Ortho Clinical Diagnostics Severance Pay Plan (the “Severance Plan”). Under the Severance Plan, benefits are payable to employees upon a position elimination, reduction in force or such other reasons the Severance Plan administrator deems appropriate, subject to an employee’s execution and non-revocation of a release agreement. Severance benefits for executives who are eligible for the Ortho Executive Bonus Program include a minimum of 12 weeks’ base salary pay plus two weeks’ base salary pay for each completed year of service, up to a maximum of 26 weeks’ base salary pay, paid in substantially equal installments.

Continuing Employees

The BCA provides that from the Ortho Effective Time until 12 months following the Ortho Effective Time, each Ortho Continuing Employee will receive base salary or wages, severance benefit protections and pension and welfare benefits that are no less favorable, in the aggregate, than those provided to such Ortho Continuing Employees immediately prior to the Ortho Effective Time.

Retention Bonuses

In connection with the Combinations, Ortho approved the grant of retention bonuses to certain employees and executive officers (the “Retention Bonuses”). The Retention Bonuses, which will be administered by the compensation committee of

306

the Ortho board of directors, are being put in place to retain key talent during the period between the signing of the BCA and the consummation of the Combinations and the 12-month period following the consummation of the Combinations. Forty percent of the Retention Bonus is expected to be paid out to recipients at the consummation of the Combinations, with the remaining 60% payable on the first anniversary thereof, subject to earlier payment upon termination if the employee or executive officer is terminated without cause. Retention Bonuses in the following amounts for the executive officers are: Mr. Busky: $384,375; Mr. Iskra: $375,000; Dr. Palianiappan: $461,250; and Mr. Schlesinger: $421,563.

Transaction Bonuses

In connection with the Combinations, Ortho approved the grant of transaction bonuses to certain employees and executive officers (the “Transaction Bonuses”). The Transaction Bonuses, which will be administered by the compensation committee of the Ortho board of directors, are being put in place to reward key talent and will be payable upon the consummation of the Combinations. Transaction Bonuses in the following amounts for the executive officers are: Mr. Smith: $937,500; Mr. Busky: $384,375; Mr. Iskra: $375,000; and Mr. Schlesinger: $421,563.

Golden Parachute Compensation

This section sets forth the information required by Item 402(t) of Regulation S-K regarding the compensation of each of Ortho’s five current named executive officers that is based on or otherwise relates to the Combinations and that will or may become payable to the named executive officers at the Ortho Effective Time or on a qualifying termination of employment on or following the Ortho Effective Time. This compensation is referred to as “golden parachute” compensation by the applicable SEC disclosure rules, and in this section we use such term to describe the Ortho Scheme-related compensation payable to Ortho’s named executive officers.

The amounts in the following table are estimates based on multiple assumptions that may not actually occur, including assumptions described in this joint proxy statement/prospectus, and do not include amounts that were vested as of the assumed closing date of the Combinations as described below. In addition, certain amounts will vary depending on the actual date of closing of the Combinations, which is presently expected to be in the first half of 2022. As a result, the actual amounts, if any, to be received by a named executive officer may differ in material respects from the amounts set forth below. In the footnotes to the table below, we refer to payments that are conditioned on the occurrence of both the Combinations and the named executive officer’s qualifying termination of employment as being payable on a “double trigger” basis and payment or benefits that are conditioned only upon the occurrence of the Combinations as being payable on a “single trigger” basis.

The potential payments in the table below are based on the following assumptions:

| • |  | the closing date of the Combinations is April 30, 2022, which is the estimated date of the completion of the Combinations solely for purposes of this golden parachute compensation disclosure; and

| • |  | the per share value of Ortho’s ordinary shares is $20.79, which is the average of the closing price of Ortho’s ordinary shares over the first five trading days following the announcement of the Combinations.

(1) | Cash severance is payable only if the named executive officer is terminated without cause or, for Messrs. Smith or Schlesinger, resigns for good reason.

307

(2) | The amounts in this column represent the value of unvested equity awards held by each named executive officer. For executives other than Mr. Smith, the amounts would vest on a double trigger basis. For Mr. Smith, the amount shown includes the value of unvested stock options ($11,365,194), which will vest on a single trigger basis and unvested restricted stock ($6,625,357), of which (i) 39,385 shares would vest on a single trigger basis pursuant to the existing terms of Mr. Smith’s restricted stock agreements and (ii) the remaining shares will vest over an expected time period of 12 months based on continued service following the closing (with acceleration in the event of being removed from the board) pursuant to terms to be agreed between Mr. Smith and Ortho’s compensation committee.

(3) | For Messrs. Smith, Iskra and Schlesinger, represents the value of continued health benefits pursuant to their Severance Agreements, which would be payable only if such named executive officers are terminated without cause or, for Messrs. Smith or Schlesinger, resign for good reason. For Messrs. Busky and Palaniappan, represents the value of continued health benefits payable to them pursuant to the Severance Plan.

(4) | Includes the value of retention bonuses and transaction bonuses approved by Ortho. Retention bonuses are payable 40% upon the closing of the Combinations and 60% upon the first anniversary, subject to continued employment through such dates; provided that the retention bonuses will become payable upon a termination without cause by Ortho. Messrs. Busky, Iskra, Palaniappan and Schlesinger are eligible for retention bonuses equal to $384,375, $375,000, $461,250, and $421,563, respectively. Transaction bonuses are payable upon the closing of the Combinations, subject to continued employment through such dates; provided that the transaction bonuses will become payable upon a termination without cause by Ortho. Messrs. Smith, Busky, Iskra and Schlesinger are eligible for transaction bonuses equal to $937,500, $384,375, $375,000 and $421,563.

Topco Positions

The post-closing Topco board of directors will consist of 12 members, comprised of: (i) four members designated by Ortho, two of whom will qualify as an “independent director” under applicable rules of Nasdaq, and (ii) eight members designated by Quidel, four of whom will qualify as an “independent director” under applicable rules of Nasdaq.

Douglas Bryant, the current President and Chief Executive Officer of Quidel, will be the Chief Executive Officer of Topco and Chair of the Topco board of directors. Additionally, Robert Bujarski, the current Chief Operating Officer of Quidel, will serve as the President and Chief Operating Officer of Topco. The chairperson of each of the Audit Committee, the Nominating and Governance Committee and the Compensation Committee shall be selected from among the eight directors designated by Quidel and each of the committees of the Topco board of directors will consist of one director designated by Ortho (who is reasonably acceptable to the Topco board of directors) and not less than two additional directors designated by Quidel.

Joseph Busky, the current Chief Financial Officer of Ortho, will serve as the Chief Financial Officer of Topco. Additionally, Michael Iskra, the current Executive Vice President of Commercial Excellence and Strategy at Ortho, will serve as the Chief Commercial Officer of Topco.

On February 15, 2022, Mr. Smith entered into a Special Advisor Agreement with Topco, pursuant to which, subject to the consummation of the Combinations, Mr. Smith will (i) transition from the role of Chief Executive Officer of Ortho and (ii) be engaged as a Special Advisor to Topco for an initial term of one year, for which services he will receive an advisory fee of $52,083 per month. Mr. Smith will receive severance payments in accordance with the terms of his existing employment agreement with Ortho and will vest 100% in his outstanding stock options, effective upon the consummation of the Combinations.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a discussion of the material U.S. federal income tax considerations to U.S. Holders (as defined below) of Ortho Shares of the Ortho Scheme and to U.S. Holders and Non-U.S. Holders of Quidel Shares of the Quidel Merger, and the material U.S. federal income tax considerations to Non-U.S. Holders of owning and disposing of Topco Shares received in the Combinations. The discussion is based on and subject to the Code, the U.S. Treasury Regulations promulgated thereunder, administrative guidance and court decisions, in each case, as of the date hereof, all of which are subject to change, possibly with retroactive effect, and to differing interpretations. The discussion assumes that Ortho shareholders hold their Ortho Shares, Quidel stockholders hold their Quidel Shares, and both Ortho shareholders and Quidel stockholders will hold their Topco Shares, as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). The discussion does not constitute tax advice and does not address all aspects of U.S. federal income taxation that may be relevant to particular holders of Ortho Shares, Quidel Shares, or Topco Shares in light of their personal circumstances, including any tax consequences arising under the Medicare contribution tax on net investment income, or to any holders subject to special treatment under the Code, such as:

| • |  | banks, thrifts, mutual funds and other financial institutions;

| • |  | real estate investment trusts and regulated investment companies;

| • |  | traders in securities who elect to apply a mark-to-market method of accounting;

| • |  | brokers or dealers in securities;

| • |  | tax-exempt organizations or governmental organizations;

| • |  | insurance companies;

| • |  | dealers or brokers in securities or foreign currency;

| • |  | individual retirement and other deferred accounts;

| • |  | U.S. Holders whose functional currency is not the U.S. dollar;

| • |  | U.S. expatriates and former citizens or long-term residents of the United States;

| • |  | “passive foreign investment companies” or “controlled foreign corporations,” and corporations that accumulate earnings to avoid U.S. federal income tax;

| • |  | persons subject to the alternative minimum tax;

| • |  | U.S. Holders who own, or are deemed to own, 5% or more of Topco’s or Ortho’s voting stock;

| • |  | persons who hold their shares as part of a straddle, hedging, conversion, constructive sale or other risk reduction transaction;

| • |  | persons who purchase or sell their shares as part of a wash sale for tax purposes;

| • |  | partnerships or other entities or arrangements classified as partnerships for U.S. federal income tax purposes, or

| • |  | other pass-through entities (and investors therein); and

| • |  | persons who received their shares through the exercise of employee stock options or otherwise as compensation or through a tax qualified retirement plan.

No rulings will be sought by Topco, Ortho or Quidel from the IRS with respect to the Combinations and there can be no assurance that the IRS or a court will not take a contrary position regarding the tax consequences described herein. The discussion does not address any non-income tax considerations or any non-U.S., state or local tax considerations. For purposes of this discussion, a “U.S. Holder” means a beneficial owner of Ortho Shares, Quidel Shares or, after the completion of the Combinations, Topco Shares that for U.S. federal income tax purposes is:

| • |  | an individual who is a citizen or resident of the United States;

| • |  | a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in the United States, any state thereof or the District of Columbia;

| • |  | an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

309

| • |  | a trust if (i) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (ii) the trust has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a U.S. person for U.S. federal income tax purposes.

A “Non-U.S. Holder” means a beneficial owner of Ortho Shares, Quidel Shares or, after the completion of the Combinations, Topco Shares who is an individual, corporation, estate or trust, in each case, that is not a U.S. Holder.

If a partnership, including for this purpose any arrangement or entity that is treated as a partnership for U.S. federal income tax purposes, holds Ortho Shares, Quidel Shares or, after the completion of the Combinations, Topco Shares, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. A holder that is a partnership for U.S. federal income tax purposes and the partners in such partnership are urged to consult their tax advisors about the U.S. federal income tax consequences of the Combinations and the ownership and disposition of the Topco Shares.

HOLDERS OF ORTHO SHARES AND QUIDEL SHARES OR, AFTER THE COMPLETION OF THE COMBINATIONS, TOPCO SHARES SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE COMBINATIONS AND THE OWNERSHIP AND DISPOSITION OF TOPCO SHARES TO THEM IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES, AS WELL AS ANY TAX CONSEQUENCES OF SUCH MATTERS ARISING UNDER THE U.S. FEDERAL TAX LAWS OTHER THAN THOSE PERTAINING TO INCOME TAX, INCLUDING ESTATE OR GIFT TAX LAWS, OR UNDER ANY STATE, LOCAL OR NON-U.S. TAX LAWS OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Material U.S. Federal Income Tax Considerations to U.S. Holders of Ortho Shares of the Ortho Scheme

The following discussion regarding U.S. federal income tax considerations relating to the Ortho Scheme assumes that the Combinations will be consummated as described in the BCA and this joint proxy statement/prospectus. The opinions described below will be based on customary assumptions and representations from Ortho and Quidel, as well as certain covenants and undertakings by each of Ortho, Quidel and other parties to the BCA. If any of the assumptions, representations, covenants or undertakings is incorrect, incomplete or inaccurate or is violated, the validity of the opinions described below may be affected and the tax consequences of the Ortho Scheme could differ from those described in this joint proxy statement/prospectus. An opinion of counsel represents counsel’s best legal judgment but is not binding on the IRS or any court, so there can be no certainty that the IRS will not challenge the conclusions reflected in the opinions or that a court would not sustain such a challenge. Neither Topco nor Ortho (or any of their affiliates) intends to request a ruling from the IRS regarding the U.S. federal income tax treatment of the Ortho Scheme. Consequently, no assurance can be given that the IRS will not challenge the tax treatment described below, or that a court would not sustain such challenge. The following discussion assumes that Ortho was not a passive foreign investment company, as described below under “Passive Foreign Investment Company Status.”

Receipt of Topco Shares and Cash in Exchange for Ortho Shares

Based on the assumptions, qualifications and limitations described herein and in the Latham & Watkins LLP opinion included as Exhibit 8.1 hereto, and the representations provided to Latham & Watkins LLP by officers of Ortho and Quidel, it is the opinion of Latham & Watkins LLP as counsel to Ortho that, for United States federal income tax purposes, the exchange of Ortho Shares for Topco Shares and cash pursuant to the Ortho Scheme, taken together with the Quidel Merger, will qualify as a transaction described in Section 351 of the Code and that, as a result, gain (but not loss) will be recognized on the exchange of Ortho Shares for a combination of cash and Topco Shares pursuant to the Ortho Scheme in an amount equal to the lesser of: (a) the excess of (i) the sum of the fair market value of the Topco Shares and the amount of cash received by such U.S. Holder over (ii) such U.S. Holder’s tax basis in its Ortho Shares, and (b) the amount of cash received by such U.S. Holder pursuant to the Ortho Scheme. The aggregate adjusted tax basis of the Topco Shares received pursuant to the Ortho Scheme will be equal to the aggregate adjusted tax basis of the Ortho Shares surrendered by the U.S. Holder, reduced by the amount of cash such U.S. Holder receives and increased by the amount of gain such U.S. Holder of Ortho Shares recognizes. The holding period of Topco Shares received pursuant to the Ortho Scheme will include the holding period of the Ortho Shares exchanged for such Topco Shares. Lastly, if a U.S. Holder acquired different blocks of Ortho Shares at different times and different prices, any gain will be determined separately with respect to each block of Ortho Shares, and the cash received will be allocated pro rata to each such block of shares. Any gain recognized by a U.S.

310

Holder in connection with such receipt of cash in exchange for Topco Shares will generally constitute capital gain, and any such capital gain will constitute long-term capital gain if the U.S. Holder’s holding period is greater than one year as of the date of the Ortho Scheme. Any gain recognized by a U.S. Holder will generally be treated as U.S. source gain.

The discussion above assumes that Section 304 of the Code is not applicable to the Ortho Scheme because Ortho shareholders who, in the aggregate, owned stock possessing at least 50% of the total combined voting power of all shares of Ortho, will not also own at least 50% of the total combined voting power of Topco following the Combinations. U.S. Holders of Ortho Shares should consult their own tax advisors regarding the possibility and consequences of the application of Section 304 of the Code to them.

U.S. Holders should consult their own tax advisors about reporting requirements and information statements that could be applicable to the Ortho Scheme and any potential penalties associated with a failure to satisfy such requirements.

Receipt of Cash in lieu of Fractional Shares

Although not entirely free from doubt, the receipt of cash in lieu of fractional Topco Shares should be treated as if a fractional share had been issued by Topco to the affected U.S. Holder as part of the Ortho Scheme, and then sold by such U.S. Holder for cash in a taxable exchange. A U.S. Holder will generally recognize gain or loss equal to the difference between the amount of the cash received instead of the fractional shares and the U.S. Holder’s adjusted tax basis in such fractional shares. Any gain or loss recognized by a U.S. Holder in connection with receipt of cash in lieu of fractional Topco Shares will generally constitute capital gain or loss, and any such capital gain or loss will constitute long-term capital gain or loss if the U.S. Holder’s holding period is greater than one year as of the date of the Ortho Scheme. The deductibility of capital losses is subject to limits. Any gain or loss recognized by a U.S. Holder will generally be treated as U.S. source gain or loss.

Passive Foreign Investment Company Status

Ortho believes that it was not a passive foreign investment company (generally, a foreign corporation that has a specified percentage of “passive” income or assets, after the application of certain “look-through” rules) for U.S. federal income tax purposes for its 2021 taxable year or any prior taxable year and does not expect to be a passive foreign investment company for its 2022 taxable year. If Ortho were a passive foreign investment company for any taxable year during which a U.S. Holder held Ortho Shares, certain adverse tax consequences could apply to such U.S. Holder as a result of the Ortho Scheme. A U.S. Holder should consult its tax advisor with respect to the U.S. federal income tax consequences of the Ortho Scheme if such U.S. Holder believes that Ortho was a passive foreign investment company for any taxable year during which it held Ortho Shares.

Material U.S. Federal Income Tax Considerations to U.S. Holders of Quidel Shares of the Quidel Merger

The following discussion regarding U.S. federal income tax considerations relating to the Quidel Merger assumes that the Combinations will be consummated as described in the BCA and this joint proxy statement/prospectus. The opinions described below will be based on customary assumptions and representations from Ortho and Quidel, as well as certain covenants and undertakings by each of Ortho, Quidel, and other parties to the BCA thereto. If any of the assumptions, representations, covenants or undertakings is incorrect, incomplete or inaccurate or is violated, the validity of the opinions described below may be affected and the tax consequences of the Quidel Merger could differ from those described in this joint proxy statement/prospectus. An opinion of counsel represents counsel’s best legal judgment but is not binding on the IRS or any court, so there can be no certainty that the IRS will not challenge the conclusions reflected in the opinions or that a court would not sustain such a challenge. Neither Topco nor Quidel (or any of their affiliates) intends to request a ruling from the IRS regarding the U.S. federal income tax treatment of the Quidel Merger. Consequently, no assurance can be given that the IRS will not challenge the tax treatment described below, or that a court would not sustain such challenge.

Based on the assumptions, qualifications and limitations described herein and in the Gibson, Dunn & Crutcher LLP opinion included as Exhibit 8.2 hereto, and representations provided to Gibson, Dunn & Crutcher LLP by officers of Ortho and Quidel, it is the opinion of Gibson, Dunn & Crutcher as counsel to Quidel that, for United States federal income tax purposes, the Quidel Merger, taken together with the Ortho Scheme, will qualify as a transaction described in Section 351(a) of the Code and no gain or loss will be recognized on the exchange of Quidel Shares solely for Topco Shares in the Quidel Merger. The aggregate adjusted tax basis of the Topco Shares received pursuant to the Quidel Merger will be equal to the

311

aggregate adjusted tax basis of the Quidel Shares surrendered by the U.S. Holder. The holding period of Topco Shares received pursuant to the Quidel Merger will include the holding period of the Quidel Shares exchanged for such Topco Shares. Lastly, if a U.S. Holder acquired different blocks of Quidel Shares at different times and different prices, any gain or loss will be determined separately with respect to each block of Quidel Shares.

U.S. Holders should consult their own tax advisors about reporting requirements and information statements that could be applicable to the Quidel Merger and any potential penalties associated with a failure to satisfy such requirements.

Material U.S. Federal Income Tax Considerations to Non-U.S. Holders of Owning and Disposing of Topco Shares Received in the Transactions

Distributions

If Topco makes distributions on Topco Shares, such distributions of cash or property on its shares will constitute dividends for U.S. federal income tax purposes to the extent paid from Topco’s current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a Non-U.S. Holder’s adjusted tax basis in its Topco Shares, but not below zero. Any excess amount will be treated as capital gain and will be treated as described below in the section relating to the sale or disposition of Topco Shares. Because Topco may not know the extent to which any distribution is a dividend for U.S. federal income tax purposes at the time it is made, for purposes of the withholding rules discussed below Topco or the applicable withholding agent may treat the entire distribution as a dividend.

Subject to the discussion below on backup withholding and foreign accounts, dividends paid to a Non-U.S. Holder of Topco Shares that are not effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty).

Non-U.S. Holders will be entitled to a reduction in or an exemption from withholding on dividends as a result of either (a) an applicable income tax treaty or (b) the Non-U.S. Holder holding Topco Shares in connection with the conduct of a trade or business within the United States and dividends being effectively connected with that trade or business. To claim such a reduction in or exemption from withholding, the Non-U.S. Holder must provide the applicable withholding agent with a properly executed (a) IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) claiming an exemption from or reduction of the withholding tax under the benefit of an income tax treaty between the United States and the country in which the Non-U.S. Holder resides or is established, or (b) IRS Form W-8ECI stating that the dividends are not subject to withholding tax because they are effectively connected with the conduct by the Non-U.S. Holder of a trade or business within the United States, as may be applicable. These certifications must be provided to the applicable withholding agent prior to the payment of dividends and must be updated periodically. Non-U.S. holders that do not timely provide the applicable withholding agent with the required certification, but that qualify for a reduced rate under an applicable income tax treaty, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such dividends are attributable), then, although exempt from U.S. federal withholding tax (provided the Non-U.S. Holder provides the appropriate certification, as described above), the Non-U.S. Holder will generally be subject to U.S. federal income tax on such dividends on a net income basis at the regular graduated U.S. federal income tax rates. In addition, a Non-U.S. Holder that is a corporation may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on its effectively connected earnings and profits for the taxable year that are attributable to such dividends, as adjusted for certain items. Non-U.S. holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

Sale or Other Disposition of Topco Shares

Subject to the discussions below on backup withholding and foreign accounts, a Non-U.S. Holder will not be subject to U.S. federal income tax on any gain realized upon the sale or other disposition of Topco Shares unless:

| • |  | the gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such gain is attributable);

312

| • |  | the Non-U.S. Holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met; or

| • |  | Topco Shares constitute U.S. real property interests, or “USRPIs,” by reason of Topco’s status as a U.S. real property holding corporation, or “USRPHC,” for U.S. federal income tax purposes.

Gain described in the first bullet point above will generally be subject to U.S. federal income tax on a net income basis at the regular graduated U.S. federal income tax rates. A Non-U.S. Holder that is a foreign corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

A Non-U.S. Holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on any gain derived from the disposition, which may be offset by certain U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States) provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, Topco does not anticipate becoming a USRPHC. Because the determination of whether Topco is a USRPHC depends on the fair market value of its USRPIs relative to the fair market value of its other business assets and its non-U.S. real property interests, however, there can be no assurance Topco will not become a USRPHC in the future. Even if Topco were to become a USRPHC, gain arising from the sale or other taxable disposition by a Non-U.S. Holder of Topco Shares will not be subject to U.S. federal income tax if Topco Shares are “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market, and such Non-U.S. Holder owned, actually and constructively, 5% or less of Topco Shares throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition or the Non-U.S. Holder’s holding period. Non-U.S. Holders are encouraged to consult their tax advisors regarding the possible consequences to them if Topco were to become a USRPHC.

Non-U.S. holders should consult their tax advisors regarding potentially applicable income tax treaties that may provide for different rules.

Information Reporting and Backup Withholding

Subject to the discussion below on foreign accounts, a Non-U.S. Holder will not be subject to backup withholding with respect to distributions on Topco Shares made to the Non-U.S. Holder, provided the applicable withholding agent does not have actual knowledge or reason to know such holder is a U.S. person and the holder certifies its non-U.S. status, such as by providing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI, or other applicable certification. However, information returns generally will be filed with the IRS in connection with any distributions (including deemed distributions) made on Topco Shares to the Non-U.S. Holder, regardless of whether any tax was actually withheld. Copies of these information returns may also be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

Information reporting and backup withholding may apply to the proceeds of a sale or other taxable disposition of Topco Shares within the United States, and information reporting may (although backup withholding generally will not) apply to the proceeds of a sale or other taxable disposition of Topco Shares outside the United States conducted through certain U.S.-related financial intermediaries, in each case, unless the beneficial owner certifies under penalty of perjury that it is a Non-U.S. Holder on IRS Form W-8BEN or W-8BEN-E, or other applicable form (and the payor does not have actual knowledge or reason to know that the beneficial owner is a U.S. person) or such owner otherwise establishes an exemption. Proceeds of a disposition of Topco Shares conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability, provided the required information or claim is timely furnished to the IRS.

Additional Withholding Tax on Payments Made to Foreign Accounts

Withholding taxes may be imposed under the legislation and administrative guidance commonly known as “FATCA,” on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30%

313

withholding tax may be imposed on dividends (including deemed dividends) paid on Topco Shares unless (a) the foreign financial institution undertakes certain diligence and reporting obligations, (b) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (c) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (a) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States-owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends (including deemed dividends) paid on Topco Shares. Because Topco may not know the extent to which a distribution is a dividend for U.S. federal income tax purposes at the time it is made, for purposes of these withholding rules, Topco or the applicable withholding agent may treat the entire distribution as a dividend. Non-U.S. Holders should consult their tax advisors regarding the potential application of these withholding provisions.

MATERIAL UK TAX CONSIDERATIONS

The following paragraphs are intended as a general guide to current UK tax law and HMRC published practice applying as of the date of this joint proxy statement/prospectus (all of which are subject to change at any time, possibly with retrospective effect) for holders of Ortho Shares who are transferring their Ortho Shares as part of the Combinations. They do not constitute legal or tax advice and do not purport to be a complete analysis of all UK tax considerations relating to the Combinations. They relate only to persons who are absolute beneficial owners of Ortho Shares who are resident for tax purposes in (and only in) the United Kingdom (except to the extent that the position of non-UK resident persons is expressly referred to).

These paragraphs may not relate to certain classes of holders of Ortho Shares, such as (but not limited to):

| • |  | persons who are connected with Ortho or Topco;

| • |  | insurance companies;

| • |  | charities;

| • |  | collective investment schemes;

| • |  | pension schemes;

| • |  | brokers or dealers in securities or persons who hold Ortho Shares or Topco Shares otherwise than as an investment;

| • |  | persons who have (or are deemed to have) acquired their Ortho Shares or Topco Shares by virtue of an office or employment or who are or have been officers or employees of Ortho, Topco or any of their affiliates; and

| • |  | individuals who are subject to UK taxation on a remittance basis.

These paragraphs do not describe all of the circumstances in which holders of Ortho Shares may benefit from an exemption or relief from UK taxation. It is recommended that all holders of Ortho Shares obtain their own tax advice. In particular, non-UK resident or domiciled persons are advised to consider the potential impact of any relevant double tax agreements.

Material UK Tax Considerations

Chargeable Gains

Subject to the comments below in relation to Section 137 of the TCGA, the receipt of Topco Shares by an Ortho shareholder in respect of, and in proportion to, such shareholder’s Ortho Shares pursuant to the Combinations may potentially be treated as a scheme of reconstruction for the purposes of UK capital gains tax or corporation tax on chargeable gain (collectively, “CGT”). On that basis, an Ortho shareholder would not be treated as making a disposal of their Ortho Shares and, therefore, no liability to CGT would arise in respect of the receipt of Topco Shares by an Ortho shareholder pursuant to the Combinations. For the purposes of CGT, the Topco Shares received by an Ortho shareholder would be treated as the same asset, acquired at the same time and for the same amount, as the Ortho Shares in respect of which they are issued.

If the “rollover” treatment described above is not available (and no assurance is or can be given that such treatment will be available), an Ortho shareholder would be treated as having made a full disposal of their Ortho Shares and may, depending on such shareholder’s personal circumstances, be liable to pay CGT.

Under Section 137 of the TCGA, any Ortho shareholder who holds (when his, her or its relevant holding is aggregated with that of persons connected with him, her or it) more than 5% of, or of any class of, shares in or debentures of Ortho will not in any event receive the possible “rollover” treatment described above if the relevant transaction has not been effected for bona fide commercial reasons or if it forms part of a scheme or arrangement of which the main purpose, or one of the main purposes, is the avoidance of liability to CGT or UK corporation tax. It is possible to apply for statutory clearance from HMRC under Section 138 of the TCGA confirming that this anti-avoidance provision does not apply. No application for clearance has been made to HMRC under Section 138 of the TCGA in respect of the receipt of Topco Shares pursuant to the Combinations. For the avoidance of doubt, please note that any Ortho shareholder who holds (when their relevant holding is aggregated with that of persons connected with them) 5% or less of, or of any class of, shares in or debentures of Ortho would not have to satisfy this anti-avoidance provision.

UK Stamp Duty and UK Stamp Duty Reserve Tax

No liability to UK stamp duty or Stamp Duty Reserve Tax will arise to holders of Ortho Shares on the issue of the Topco Shares pursuant to the Combinations.

315

COMPARISON OF RIGHTS OF STOCKHOLDERS OF QUIDEL, ORTHO AND TOPCO

Quidel and Topco are each organized under the laws of the State of Delaware. Ortho is organized under the laws of England and Wales. If the Combinations are consummated, the Quidel stockholders and Ortho shareholders will become stockholders of Topco. After giving effect to the Combinations, the rights of stockholders of Topco and the relative powers of the Topco board of directors will be governed by Delaware law and by the Topco Charter and Topco Bylaws. Each Topco Share will be issued pursuant to, and will carry with it the rights and obligations set forth in, the Topco Charter. This section summarizes material differences between the rights of Quidel stockholders and Ortho shareholders before consummation of the Combinations and the rights of Topco stockholders after consummation of the Combinations. These differences in stockholder rights result from the differences between the respective organizational documents of Quidel, Ortho and Topco and the applicable governing law.

The following summary does not include a description of rights or obligations under the U.S. federal securities laws, English securities law or relevant Nasdaq listing requirements or standards.

The following summary is not a complete statement of the rights of the Quidel stockholders, the Ortho shareholders or the Topco stockholders or a complete description of the specific provisions referred to below. The identification of specific differences is not intended to indicate that other equally significant or more significant differences do not exist. This summary is qualified in its entirety by reference to Quidel’s, Ortho’s and Topco’s organizational documents, which you are urged to read carefully.

The form of the Topco Charter, the Topco Bylaws, the Quidel Charter, the amendment to the Quidel Charter, the Quidel Bylaws and Ortho’s articles of association are attached hereto as Exhibit 3.1, Exhibit 3.2, Exhibit 3.3, Exhibit 3.4, Exhibit 3.5 and Exhibit 3.6, respectively, of this joint proxy statement/prospectus and are incorporated herein by reference.

The Quidel Bylaws provide that the board of directors shall have no fewer than five nor more than 12 members, with the size at any time to be established exclusively by resolution of the board of directors. Under the Quidel Bylaws, each member of the Quidel board of directors shall hold office until the next annual meeting of stockholders, and until such director’s successor is elected and qualified or until such director’s earlier death, resignation or removal. The board of directors are also empowered by the Quidel Bylaws to appoint directors to fill a vacancy or as an addition to the existing board of directors in accordance with the Quidel Bylaws. |  |  |  | manner provided in the bylaws. The Topco Bylaws to be in effect as of the Ortho Effective Time provide that the board of directors shall have no fewer than five nor more than 14 members, with the size at any time to be established exclusively by resolution of the board of directors. Under the Topco Bylaws, each member of the Topco board of directors shall hold office until the next annual meeting of stockholders, and until such director’s successor is elected and qualified or until such director’s earlier death, resignation or removal. The board of directors are also empowered by the Topco Bylaws to appoint directors to fill a vacancy or as an addition to the existing board of directors in accordance with the Topco Bylaws.
Nomination and Appointment of Directors
Pursuant to the Quidel Bylaws, each director shall be elected by a plurality of the voting power of Quidel’s capital stock present in person or represented by proxy at a meeting of stockholders and entitled to vote on the election of directors. |  | Subject to the provisions of Ortho’s articles of association, Ortho may, by ordinary resolution of the shareholders or a decision of the directors, elect any person to be a director, as an addition to the existing board, provided the total number of directors does not exceed the maximum number fixed, provided, further, that a vacancy caused by the departure of a Carlyle Stockholder appointee may only be filled by the Carlyle Stockholder. However, any person that is not a director retiring from the existing board must be recommended by the board or the person must have confirmed in writing to Ortho their willingness to be elected as a director. Ortho’s articles of association provide for a staggered board consisting of three classes of directors. Directors of each class are chosen for three-year terms, with only one class of directors being elected at each annual meeting of shareholders. At the first annual meeting of shareholders, the terms of the Class I directors (other than a Carlyle Stockholder appointee who is a Class I director) will expire and Class I directors (other than a Carlyle Stockholder |  | After the closing of the Combinations, directors will be identified and recommended by the Nominating and Governance Committee of the Topco board of directors, although the Topco Bylaws also permit stockholders to nominate directors subject to certain conditions. Pursuant to the Topco Bylaws, directors shall be elected by a plurality of the voting power of Topco Shares present in person or represented by proxy at a meeting of stockholders and entitled to vote on the election of directors. In addition, the Carlyle Stockholder has the right to appoint directors while it holds at least a certain percentage of Topco Shares, as described in the section entitled “Stockholders Agreement / Deed of Irrevocable Undertaking— Stockholders Agreement” of this joint proxy statement/prospectus.

At each succeeding annual meeting, directors (other than Carlyle Stockholder appointees) will be elected for a full term of three years to succeed the directors of the class whose terms expire at such annual general meeting. |  |
Removal of Directors and Vacancies
Under the DGCL, vacancies may be filled as provided for in the bylaws of a corporation. The Quidel Bylaws provide that directors may be removed, with or without cause, solely by the affirmative vote of the holders of a majority of the total voting power of all classes of outstanding stock of Quidel entitled to vote in the election of directors. The Quidel Bylaws provide that vacancies on the Quidel board of directors will be filled by the affirmative vote of a majority of the directors then in office. |  | Ortho may, by ordinary resolution, remove any director from office. No special notice need be given of any resolution to remove a director in accordance with Ortho’s articles of association and no director proposed to be removed in accordance with Ortho’s articles of association has any special right to protest against their removal. Where a Carlyle Stockholder appointee is removed the Carlyle Stockholder may nominate his replacement provided the conditions for such an appointment subsist. Certain other procedural requirements under the UK Companies Act must also be followed such as allowing the director to make representations against his or her removal either at the meeting or in writing. Subject to the provisions of Ortho’s articles of association, Ortho may, by ordinary resolution of the shareholders or a decision of the directors, elect any person to be a director to fill a casual vacancy.

Remuneration of Directors
The Quidel Bylaws authorize the board of directors to set director compensation, and generally do not give stockholders the right to approve director compensation. |  | Ortho’s articles of association state that each of the directors is entitled to remuneration as determined by the board for their service as directors and other services undertaken for Ortho. Each director may be paid his expenses in connection with such director’s attendance at meetings of the board or committees of the board or general meetings or separate meetings of the holders of class of shares or of debentures, or otherwise in connection with the exercise of powers and the discharge of responsibilities in relation to Ortho. |  | The Topco Bylaws authorize the board of directors to set director compensation, and generally do not give stockholders the right to approve director compensation.
Annual Meetings of Stockholders
Under the DGCL, the annual meeting of stockholders shall be held at such place, on such date and at such time as provided in a corporation’s bylaws. The Quidel Bylaws provide that Quidel must hold an annual meeting of stockholders on such date and at such time as may be fixed by resolution of the Quidel board of directors. Pursuant to the DGCL, any stockholder or director may petition the Court of Chancery to order a meeting to elect directors if the annual meeting has not been held within 30 days of the date set for such meeting or 13 months following the date the previous annual meeting was held. |  | In accordance with the UK Companies Act, Ortho is required in each year to hold an annual general meeting in addition to any other general meetings in that year and to specify the meeting as such in the notice convening it. The annual general meeting shall be convened whenever and wherever the board sees fit, subject to the requirements of the UK Companies Act, which state that a public limited company must hold an annual general meeting in each six-month period following the company’s annual accounting reference date. |  | Under the DGCL, the annual meeting of stockholders shall be held at such place, on such date and at such time as provided in a corporation’s bylaws.

Notice of Stockholder Meetings
Generally, the DGCL requires that notice to stockholders of the place (if any), date, and hour, and means of remote communication (if any) of each annual and special meeting of stockholders be given at least 10 days, but no more than 60 days, before the meeting date. The Quidel Bylaws provide that notice of any meeting shall be given not less than 10 nor more than 60 days before the date of the meeting. Pursuant to the DGCL, notice of a meeting of stockholders to vote upon a merger or a sale of all or substantially all of the corporation’s assets must be delivered at least 20 days before the meeting date. In the case of a special meeting, the notice must also state the purpose or purposes for which the meeting is called. |  | Under the UK Companies Act, 21 clear days’ notice must be given for an annual general meeting and any resolutions to be proposed at the meeting. At least 14 clear days’ notice (but no more than 60 days’ notice under Ortho’s articles of association) is required for any other general meeting. In addition, certain matters, such as the removal of directors or auditors, require special notice, which is 28 clear days’ notice. Ortho shareholders may in all cases consent to a shorter notice period, the proportion of shareholders’ consent required being 100% of those entitled to attend and vote in the case of an annual general meeting and, in the case of any other general meeting, a majority in number of the members having a right to attend and vote at the meeting, being a majority who together hold not less than 95% in nominal value of the shares giving a right to attend and vote at the meeting. |  | Generally, the DGCL requires that notice to stockholders of the place (if any), date, and hour, and means of remote communication (if any) of each annual and special meeting of stockholders be given at least 10 days, but no more than 60 days, before the meeting date. The Topco Bylaws provide that notice of any meeting shall be given not less than 10 nor more than 60 days before the date of the meeting. Pursuant to the DGCL, notice of a meeting of stockholders to vote upon a merger or a sale of all or substantially all of the corporation’s assets must be delivered at least 20 days before the meeting date. In the case of a special meeting, the notice must also state the purpose or purposes for which the meeting is called.
Quorum at Stockholder Meetings
The Quidel Bylaws provide that the holders of a majority of the voting power of Quidel’s outstanding capital stock entitled to vote, present in person or represented by proxy, constitute a quorum at all meetings of stockholders except as otherwise provided by law or Quidel’s restated certificate of incorporation (the “Quidel Charter”). |  | Under Ortho’s articles of association, no business shall be transacted at any general meeting unless a quorum is present. At least two Ortho shareholders present in person or by proxy and entitled to vote shall be a quorum for all purposes. |  | The Topco Bylaws provide that the holders of a majority of the voting power of Topco’s outstanding capital stock entitled to vote, present in person or represented by proxy, constitute a quorum at all meetings of stockholders except as otherwise provided by law or the Topco Charter.
Stockholder Voting Rights

An ordinary resolution is passed on a poll if it is approved by holders representing a simple majority of the total voting rights of shareholders present, in person or by proxy, who, being entitled to vote, vote on the resolution. A special resolution is passed on a poll if it is approved by holders representing not less than 75% of the total voting rights of shareholders present (in person or by proxy) who (being entitled to vote) vote on the resolutions. |  | any meeting may do so in person or by proxy. Each Topco Share entitles its holder to one vote. Generally, under the Topco Bylaws, when a quorum is present, the affirmative vote of a majority of the shares present in person or represented by proxy at a meeting of stockholders and entitled to vote on a matter shall be the act of the stockholders.
Approval of Mergers and Business Combinations
The DGCL requires, with limited exceptions, a merger, consolidation or sale of substantially all of the assets of a corporation to be approved by the corporation’s board of directors and a majority of the issued and outstanding shares entitled to vote thereon. However, if a target corporation is listed on a national securities exchange or its shares are held of record by more than 2,000 holders immediately prior to the execution of a merger agreement, then the target corporation may opt into Section 251(h) of the DGCL. If the parties opt into Section 251(h) of the DGCL and a sufficient number of shares are accepted in the tender offer that are required to approve a merger, then the merger may be consummated without a vote of the target stockholders. The Quidel Bylaws provide that Quidel expressly elects not to be governed by Section 203 of the DGCL, which restricts certain transactions with stockholders who own 15% or more of a corporation’s voting stock. |  | Neither the UK Companies Act nor Ortho’s articles of association stipulate a specific approval in respect of mergers and business combinations generally. However, the manner in which a merger or business approval is structured may require certain specific approvals. For example, as is the case for the Combinations, a business combination by way of a scheme of arrangement requires, according to the UK Companies Act, approval of the terms of the scheme of arrangement and the scheme itself by a majority in number of shareholders representing 75% in value of share capital held by the members who vote in person or by proxy as well as the receipt of the required approval of the scheme of arrangement by the Court. |  | The DGCL requires, with limited exceptions, a merger, consolidation or sale of substantially all of the assets of a corporation to be approved by the corporation’s board of directors and a majority of the issued and outstanding shares entitled to vote thereon. However, if a target corporation is listed on a national securities exchange or its shares are held of record by more than 2,000 holders immediately prior to the execution of a merger agreement, then the target corporation may opt into Section 251(h) of the DGCL. If the parties opt into Section 251(h) of the DGCL and a sufficient number of shares are accepted in the tender offer that are required to approve a merger, then the merger may be consummated without a vote of the target stockholders. The Topco Charter provides that Topco expressly elects not to be governed by Section 203 of the DGCL, which restricts certain transactions with stockholders who own 15% or more of a corporation’s voting stock.

Mandatory Tender Offer and Squeeze-out Thresholds
Pursuant to the DGCL, a corporation or other entity owning at least 90% of the outstanding shares of a subsidiary corporation may effect a merger with or into such subsidiary by resolution of the board of directors of the parent and without any action on the part of the board of directors or the other stockholders of the subsidiary. |  | Pursuant to Sections 979 to 991 of the UK Companies Act, where a takeover offer has been made for Ortho and the offeror has acquired or unconditionally contracted to acquire not less than 90% in value of the Ortho Shares to which the offer relates and not less than 90% of the voting rights carried by those Ortho Shares, the offeror may give notice to the holder of any Ortho Shares to which the offer relates which the offeror has not acquired or unconditionally contracted to acquire that he wishes to acquire, and is entitled to so acquire, those Ortho Shares on the same terms as the general offer. The offeror would do so by sending a notice to the outstanding minority Ortho shareholders telling them that it will compulsorily acquire their Ortho Shares. Such notice must be sent within three months of the last day on which the offer can be accepted in the prescribed manner. The squeeze-out of the minority Ortho shareholders can be completed at the end of six weeks from the date the notice has been given, subject to the minority Ortho shareholders failing to successfully lodge an application to the court to prevent such squeeze-out any time prior to the end of those six weeks following which the offeror can execute a transfer of the outstanding Ortho Shares in its favor and pay the consideration to Ortho, which would hold the consideration on trust for the outstanding minority Ortho shareholders.

Indemnification of Directors and Officers
The DGCL permits a corporation to indemnify any persons who are, or are threatened to be made, parties to any threatened, pending or completed legal action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe that the person’s conduct was unlawful.

Authority to Allot
Under the DGCL, if the corporation’s charter or certificate of incorporation so provides, the board of directors has the power to authorize the issuance of stock. It may authorize capital stock to be issued for consideration consisting of cash, any tangible or intangible property or any benefit to the corporation or any combination thereof. |  | Under the UK Companies Act, the directors of a company must not allot shares or grant rights to subscribe for or to convert any security into shares unless an exception applies or an ordinary resolution to the contrary has been passed by shareholders in a general meeting or the articles of association provide otherwise, in each case in accordance with the provisions of the UK Companies Act. Pursuant to Ortho’s articles of association, Ortho’s directors are authorized to exercise all of the powers of the company to allot shares in Ortho, and to grant rights to subscribe for or to convert any security into shares in Ortho, up to a maximum aggregate nominal value of $10,000 (in addition to any authority to allot that has not yet expired granted to the board prior to the date of the adoption of Ortho’s articles of association) for a period expiring (unless previously renewed, varied or revoked by Ortho in a general meeting) on February 1, 2026. |  | Under the DGCL, if the corporation’s charter or certificate of incorporation so provides, the board of directors has the power to authorize the issuance of stock.

Dividends
The DGCL provides that, subject to any restrictions in a corporation’s certificate of incorporation, dividends may be declared from the corporation’s surplus, or if there is no surplus, from its net profits for the fiscal year in which the dividend is declared and for the preceding fiscal year. Dividends may not be declared out of net profits, however, if the corporation’s capital has been diminished to an amount less than the aggregate amount of all capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets until the deficiency in the amount of capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets is repaired. |  | Ortho may, by ordinary resolution of the Ortho shareholders, declare dividends out of profits available for distribution in accordance with the respective rights of Ortho shareholders but no such dividend shall exceed the amount recommended by the directors. The Ortho board may from time to time pay Ortho shareholders such interim dividends as they appear to the board to be justified by Ortho’s financial position. Subject to any special rights attaching to or the terms of issue of any share, all dividends shall be declared and paid according to the amounts paid up on the Ortho Shares and shall be apportioned and paid pro rata according to the amounts paid up on the Ortho Shares during any part or parts of the period in respect of which the dividend is paid. No dividend or other moneys payable by Ortho on or in respect of any share shall bear interest against Ortho unless otherwise provided by the rights attached to the share or the provisions of another agreement between the Ortho shareholder and Ortho. Any dividend unclaimed after a period of 12 years from the date such dividend became due for payment shall be forfeited and cease to remain owing. Dividends may be declared or paid in any currency and the Ortho board may decide the rate of exchange for any currency conversions that may be required, and how any costs involved are to be met, in relation to the currency of any dividend. Any general meeting declaring a dividend may by ordinary resolution of the Ortho shareholders, upon the recommendation of the Ortho board, direct payment or satisfaction of such dividend wholly or in part by the distribution of non-cash assets of equivalent value, including shares or other securities in any company.

Repurchases and Redemptions
Pursuant to the DGCL, a corporation may purchase, redeem, receive, take or otherwise acquire, own and hold, sell, lend, exchange, transfer or otherwise dispose of, pledge, use and otherwise deal in and with its own shares; provided, however, that no corporation shall: (i) purchase or redeem its own shares of capital stock for cash or other property when the capital of the corporation is impaired or when such purchase or redemption would cause any impairment of the capital of the corporation, except that a corporation may purchase or redeem out of capital any of its own shares which are entitled upon any distribution of its assets, whether by dividend or in liquidation, to a preference over another class or series of its stock, or, if no shares entitled to such a preference are outstanding, any of its own shares, if such shares will be retired upon their acquisition and the capital of the corporation reduced; (ii) purchase, for more than the price at which they may then be redeemed, any of its shares which are redeemable at the option of the corporation; or (iii) redeem any of its shares unless their redemption is authorized by a subsection of the DGCL and then only in accordance with such section and the certificate of incorporation.

The resolution authorizing the purchase must specify a date, not being later than five years after the passing of the resolution, on which the authority to purchase is to expire. Ortho may issue shares which are to be redeemed or are to be liable to be redeemed at the option of Ortho or the holder. The Ortho board may determine the terms, conditions and manner of redemption of shares provided that it does so before the shares are allotted. The 50,001 deferred shares of £1.00 each in the capital of Ortho can be redeemed by the Ortho board for nil value at the Ortho board’s discretion. |  | Pursuant to the DGCL, a corporation may purchase, redeem, receive, take or otherwise acquire, own and hold, sell, lend, exchange, transfer or otherwise dispose of, pledge, use and otherwise deal in and with its own shares; provided, however, that no corporation shall: (i) purchase or redeem its own shares of capital stock for cash or other property when the capital of the corporation is impaired or when such purchase or redemption would cause any impairment of the capital of the corporation, except that a corporation may purchase or redeem out of capital any of its own shares which are entitled upon any distribution of its assets, whether by dividend or in liquidation, to a preference over another class or series of its stock, or, if no shares entitled to such a preference are outstanding, any of its own shares, if such shares will be retired upon their acquisition and the capital of the corporation reduced; (ii) purchase, for more than the price at which they may then be redeemed, any of its shares which are redeemable at the option of the corporation; or (iii) redeem any of its shares unless their redemption is authorized by a subsection of the DGCL and then only in accordance with such section and the certificate of incorporation.

Standard of Conduct for Directors
The DGCL does not contain specific provisions setting forth the standard of conduct of a director.

In general, directors have a duty to act without self-interest, on a well-informed basis and in a manner they reasonably believe to be in the best interest of the stockholders. Directors of a Delaware corporation owe fiduciary duties of care and loyalty to the corporation and to its stockholders. The duty of care generally requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances.

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement or annual report, as applicable, addressed to those stockholders. As permitted by the Exchange Act, only one copy of this joint proxy statement/prospectus is being delivered to stockholders residing at the same address, unless such stockholders have notified the company whose shares they hold of their desire to receive multiple copies of this joint proxy statement/prospectus. This process, which is commonly referred to as “householding,” potentially provides extra convenience for stockholders and cost savings for companies.

If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate joint proxy statement/prospectus, or if you are receiving multiple copies of this joint proxy statement/prospectus and wish to receive only one, please contact Quidel or Ortho, as applicable, at the address identified below. Quidel and Ortho will promptly deliver, upon oral or written request, a separate copy of this joint proxy statement/prospectus to any Quidel stockholder or Ortho shareholder residing at an address to which only one copy was mailed. Requests for additional copies should be directed to: Quidel Corporation, Attention: Phillip S. Askim, VP, Associate General Counsel & Secretary, 9975 Summers Ridge Road, San Diego, California 92121, United States of America, Telephone (858) 552-1100, or Innisfree M&A Incorporated, Quidel’s proxy solicitor, by calling (877) 750-0537.

FUTURE STOCKHOLDER PROPOSALS

Topco

Assuming consummation of the Combinations, Topco stockholders will be entitled to present proposals for consideration at forthcoming Topco stockholder meetings, provided that they comply with the proxy rules promulgated by the SEC and the Topco Charter. The deadline for submission of all Topco stockholder proposals to be considered for inclusion in Topco’s proxy statement for its next annual meeting will be disclosed in a subsequent filing with the SEC.

Quidel

Quidel held its 2021 Annual Meeting of Stockholders on May 18, 2021. Quidel does not intend to hold an annual meeting of stockholders in 2022, but this joint proxy statement/prospectus includes certain matters that would have been proposals at its 2022 Annual Meeting of Stockholders, had it been held.

Ortho

Ortho does not intend to hold an annual meeting of shareholders in 2022, and will hold an annual meeting in 2022 only if the Combinations are not completed before June 16, 2022.

NO APPRAISAL RIGHTS FOR QUIDEL STOCKHOLDERS

Appraisal rights are statutory rights under the DGCL that enable stockholders who object to certain extraordinary transactions to demand that the corporation pay such stockholders the fair value of their shares instead of receiving the consideration offered to stockholders in connection with the extraordinary transaction. However, appraisal rights are not available in all circumstances. Appraisal rights are not available to Quidel stockholders in connection with the Combinations.

NO DELAWARE APPRAISAL RIGHTS FOR ORTHO SHAREHOLDERS

As shareholders of a UK public limited company, Ortho shareholders do not have appraisal rights similar to the statutory rights under the DGCL that enable shareholders who object to certain extraordinary transactions to demand that the corporation pay such shareholders the fair value of their shares instead of receiving the consideration offered to shareholders in connection with the extraordinary transaction.

LEGAL MATTERS

The legality of the Topco Shares issuable in the Combinations will be passed upon for Topco by Latham & Watkins LLP.

EXPERTS

The consolidated financial statements of Quidel Corporation at December 31, 2021 and 2020, and for each of the three years in the period ended December 31, 2021, incorporated by reference in the joint proxy statement/prospectus and Amendment No. 1 to the Registration Statement of Coronado Topco, Inc., have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their report incorporated by reference herein, and are included in reliance upon such report given on the authority of such firm as experts in accounting and auditing.

The financial statements incorporated in this joint proxy statement/prospectus by reference to the Annual Report on Form 10-K of Ortho Clinical Diagnostics Holdings plc for the year ended January 2, 2022 have been so incorporated in reliance on the report of PricewaterhouseCoopers LLP, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting.

PwC completed an independence assessment to evaluate the services and relationships with Ortho and its affiliates that may bear on PwC’s independence under the SEC and the PCAOB (United States) independence rules for an audit period commencing January 1, 2018, PwC informed Ortho that certain of its member firms within PricewaterhouseCoopers International Limited, each member firm of which is a separate legal entity (“PwC member firm”), were engaged to perform non-audit services by and had relationships with entities that are under common control with Ortho. These non-audit services and relationships are not in accordance with the SEC and PCAOB auditor independence rules and are described below:

| • |  | From April 2019 to September 2020, a PwC member firm assisted in the preparation and submission of two statistical reports to a non-tax authority for an entity under common control with Ortho. The fees for these services were approximately $1,600.

| • |  | From April 2018 to March 2019, a PwC covered person, who was not involved in the audit of Ortho, held an impermissible financial interest in an affiliate of Ortho.

| • |  | From August 2017 to January 2018, a PwC member firm had a business relationship with an entity under common control with Ortho. The fees for these services were approximately $180,000.

| • |  | From November 2018 to February 2019, a PwC member firm provided an expert service to an entity under common control with Ortho. The fees for these services were approximately $360,000 (fees for the services were not invoiced or collected).

| • |  | During March 2019, a PwC member firm held custody of documents and provided a registered office address for an entity under common control with Ortho. There were no fees earned for this service.

PwC provided an overview of the facts and circumstances surrounding the services and relationships to Ortho’s audit committee and management, including the entities involved, the nature of the relationships, where applicable, an approximation of the fees earned related to the services and relationships and other relevant factors. Considering the facts presented, Ortho’s audit committee and PwC have concluded that the relationships would not impair PwC’s application of objective and impartial judgment on any matters encompassed within the audit engagement performed by PwC for Ortho’s consolidated financial statements for each of the three years in the period ended January 2, 2022, and that no reasonable investor would conclude otherwise.

ARTICLE I

THE COMBINATIONS

Section 1.1. The Combinations.

(a) Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with English Law (including the UK Scheme Regulations), the Orca Scheme and the DGCL, as applicable, at the Orca Effective Time, having received the Orca Scheme Order which shall have been duly filed with the Registrar, the Orca Scheme shall occur, upon the consummation of which all Orca Shares, other than the Excluded Orca Shares, will be transferred to Computershare Limited or another company mutually acceptable to Laguna and Orca and falling within Section 67(6) of the Finance Act 1986 (such company, a “DR Nominee”) on behalf of Topco in exchange for Topco Shares, such that Orca will become a wholly-owned direct subsidiary of the DR Nominee on behalf of Topco and Topco shall allot and issue the Topco Shares in accordance with Section 1.4. The Orca Scheme shall have the effects set forth in this Agreement and the Orca Scheme Terms. The parties shall take all actions necessary so that the articles of association of Orca shall be amended as part of the Orca Scheme, and as

A-2

of the Orca Effective Time, to read in their entirety in the form attached hereto as Exhibit A, and such articles, as so amended, shall be the articles of Orca until thereafter changed or amended as provided therein or by applicable Law. In this Clause 1.1(a), references to Orca Shares being transferred to the DR Nominee on behalf of Topco shall, to the extent that such Orca Shares are already held by the DR Nominee at the Orca Effective Time, be construed as references to the DR Nominee ceasing to hold such Orca Shares on behalf of any other person and commencing holding such Orca Shares on behalf of Topco. As of the Orca Effective Time, the sole member of the board of directors of Orca shall be an individual reasonably acceptable to Laguna, and shall hold office in accordance with the articles of association of Orca, as amended as part of the Orca Scheme. As of the Orca Effective Time, the officers of Orca shall be individuals reasonably acceptable to Laguna, and shall hold office in accordance with the articles of association of Orca, as amended as part of the Orca Scheme.

(b) Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the DGCL, at the Laguna Effective Time, the Laguna Merger shall occur, upon the consummation of which U.S. Merger Sub shall be merged with and into Laguna, the separate existence of U.S. Merger Sub shall thereupon cease and Laguna shall continue as the surviving corporation (the “Laguna Merger Surviving Corporation”). The Laguna Merger shall be preceded by the completion of the Orca Scheme. As a result of the Laguna Merger, Laguna shall become a wholly owned direct Subsidiary of Topco. The Laguna Merger shall have the effects specified in the DGCL. Without limiting the generality of the foregoing, from and after the Laguna Effective Time, the Laguna Merger Surviving Corporation shall possess all the rights, powers, privileges and franchises and be subject to all of the obligations, liabilities and duties of Laguna and U.S. Merger Sub, all as provided under the DGCL. At the Laguna Effective Time, the certificate of incorporation of Laguna shall be amended to read in its entirety in the form attached hereto as Exhibit B, and as so amended, shall be the certificate of incorporation of the Laguna Merger Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law. The parties shall take all actions necessary so that the bylaws of Laguna shall be amended as of the Laguna Effective Time to read in their entirety in the form attached hereto as Exhibit C, and such bylaws, as so amended, shall be the bylaws of the Laguna Merger Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law. As of the Laguna Effective Time, the sole member of the board of directors of U.S. Merger Sub shall be an individual reasonably acceptable to Laguna, and shall hold office in accordance with the certificate of incorporation and bylaws of the Laguna Merger Surviving Corporation. As of the Laguna Effective Time, the sole officer of Laguna immediately prior to the Laguna Effective Time shall be an individual reasonably acceptable to Laguna, and shall hold office in accordance with the certificate of incorporation and bylaws of the Laguna Merger Surviving Corporation.

Section 1.2. Closing. Topco and Orca shall each use their respective reasonable best efforts to obtain the Orca Scheme Order, including by promptly making all necessary applications under, and otherwise satisfying the requirements of, the UK Scheme Regulations, as promptly as practicable after the date hereof (but excluding any obligation to agree to any conditions or modifications to the Orca Scheme in respect of any substantive action or agreement) and subject to the satisfaction or (to the extent permitted by applicable Law) waiver of the conditions set forth in Article VI (other than those conditions that by their terms are to be satisfied at the Closing, but subject to the satisfaction or (to the extent permitted by applicable Law) waiver of such conditions), and will appear by counsel reasonably satisfactory to the parties (the “Scheme Counsel”) at a hearing (an “Orca Sanction Hearing”) to seek an order of the High Court of England and Wales (the “English Court”) under the UK Scheme Regulations sanctioning the Orca Scheme (the “Orca Scheme Order”) which shall be effective once the Orca Scheme Order is duly filed with the Registrar in accordance with Section 1.3(a) (such date the “Scheme Effective Date”). The date on which the Orca Scheme Order is filed with the Registrar in accordance with Section 1.3(a) shall be the “Closing Date,” and the time at which the Registrar receives the Orca Scheme Order shall be the “Closing.” Following the receipt of the Orca Scheme Order, the parties shall not take any action to amend, modify, rescind or terminate the Orca Scheme Order. For purposes of this Agreement, “Business Day” means a day (other than a Saturday or Sunday) on which banks are open for general business in (i) London, England and (ii) New York, State of New York, United States of America.

Section 1.3. Effective Time.

(a) The parties shall make or cause to be made all filings and recordings required by English Law and the DGCL in connection with the due and effective implementation of the Orca Scheme, including the due filing of the Orca Scheme Order with the Registrar of Companies in England and Wales (the “Registrar”), as required in accordance with the UK Scheme Regulations and applicable Law as promptly as practicable following the grant by the English Court of the Orca Scheme Order.

(b) Subject to the terms and conditions set forth in this Agreement, on the date on which the Orca Scheme Order is duly filed with the Registrar, and as soon as practicable after such time, and in no event prior thereto, Laguna shall file a

A-3

certificate of merger relating to the Laguna Merger (the “Laguna Certificate of Merger”) with the Secretary of State of the State of Delaware in accordance with the relevant provisions of the DGCL and shall make all other filings or recordings required under the DGCL, which Laguna Certificate of Merger shall specify the Laguna Effective Time contemplated by Section 1.3(c).

(c) The parties agree that the Combinations shall become effective sequentially (i) with the Orca Scheme Order becoming effective on the Scheme Effective Date at the time the Orca Scheme Order is duly delivered to the Registrar, such time being the “Orca Effective Time” and (ii) with the Laguna Certificate of Merger providing that the Laguna Merger shall become effective on the Scheme Effective Date immediately following the Orca Effective Time (or such subsequent time as Orca and Laguna shall agree and as shall be specified in the Laguna Certificate of Merger, and in no event prior to the Orca Effective Time), such time being the “Laguna Effective Time”.

Section 1.4. Effect of the Orca Scheme on Orca Shares. As a result of the Orca Scheme and without any action on the part of Topco (other than in respect of the allotment and issuance of Topco shares in accordance with Section 1.7), Orca, or the holder of any capital stock of Topco or Orca, at the Orca Effective Time:

(a) Transfer of Orca Shares. Each issued and outstanding Orca Share at the Orca Effective Time (other than Orca Shares that are held in the treasury of Orca immediately prior to the Orca Effective Time (each, an “Excluded Orca Share”)) shall be transferred to the DR Nominee (for the benefit of Topco) in accordance with the terms of this Agreement and the Orca Scheme such that the holders of the Orca Shares (and any holders of depositary interests in Orca Shares) shall cease to have any rights with respect to the Orca Shares, except their rights under the Orca Scheme. At the Orca Effective Time, or as soon as reasonably practicable thereafter, the statutory register of members for Orca shall be updated in accordance with the Orca Scheme to reflect the transfer of the Orca Shares under the Orca Scheme to Topco. In this Clause 1.4(a), references to Orca Shares being transferred to the DR Nominee (for the benefit of Topco) shall, to the extent that such Orca Shares are already held by the DR Nominee at the Orca Effective Time, be construed as references to the DR Nominee ceasing to hold such Orca Shares for the benefit of any other person and commencing holding such Orca Shares for the benefit of Topco.

(b) Topco Share and Cash Allotment. Subject to and in consideration for the transfer of the Orca Shares pursuant to Section 1.4(a), Topco shall, under the Orca Scheme and subject to the terms and conditions thereof and subject to Section 1.7, allot and issue, for each issued and outstanding Orca Share at the Orca Effective Time (other than the Excluded Orca Shares), (i) the Orca Exchange Ratio of a validly issued, fully paid and non-assessable Topco Share, having the terms set forth in the Topco Charter together with all rights at the Orca Effective Time or thereafter attached thereto, including the right to receive and retain all dividends and other distributions (if any) (the “Share Portion”) and (ii) the right to receive from Topco $7.14 in cash (the “Cash Portion” and, together with the Share Portion, the “Orca Scheme Consideration”) immediately following the Orca Effective Time, without any interest thereon and, in each case, subject to any withholding Taxes required by applicable Law in accordance with Section 1.10. The parties’ obligations in relation to the allotment and issue of the Topco Shares will be as set out more specifically in the Orca Scheme.

(c) Exchange of Interests in Orca Shares. As of the Orca Effective Time, the DR Nominee on behalf of Topco shall (to the extent that it is not already the holder) become the holder of all such Orca Shares and each depositary receipt with depositary intermediaries participating in the centralized depositary and clearing system managed by Computershare Trust Company, N.A. (the “Orca Depositary”) previously representing any such shares shall thereafter be represented by Topco Shares allotted for such Orca Shares in the Orca Scheme in accordance with the Orca Scheme Terms, and Section 1.4(a), Section 1.4(b) and Section 1.7 of this Agreement.

(d) No Fractional Shares. No fractional Topco Shares will be issued in the Orca Scheme to any holder of Orca Shares. Notwithstanding any other provision of this Agreement, each holder of Orca Shares converted pursuant to Section 1.4Section 1.5(a) whom would otherwise have been entitled to receive a fraction of a Topco Share shall receive from the Exchange Agent, in lieu thereof, cash (without interest) in an amount representing such holder’s proportionate interest in the net proceeds from the sale by the Exchange Agent on behalf of all such holders of Topco Shares which would otherwise be issued (the “Excess Orca Scheme Shares”). The sale of the Excess Orca Scheme Shares by the Exchange Agent shall be executed on Nasdaq, and shall be executed in round lots to the extent practicable. Until the net proceeds of such sale or sales have been distributed to such former holders of Orca Shares, the Exchange Agent shall hold such proceeds in trust for such holders (the “Fractional Interests Trust”). Topco shall pay all commissions, transfer Taxes and other out-of-pocket transaction costs incurred in connection with such sale of the Excess Orca Scheme Shares. The Exchange Agent shall determine the portion of the Fractional Interests Trust to which each holder of Orca Shares shall be entitled, if any, by

A-4

multiplying the amount of the aggregate net proceeds comprising the Fractional Interests Trust by a fraction, the numerator of which is the amount of fractional Topco Shares to which such former holder of Orca Shares is entitled and the denominator of which is the aggregate amount of fractional Topco Shares to which all holders of Orca Shares are entitled. As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of Orca Shares in lieu of fractional Topco Shares, the Exchange Agent shall make available such amounts to such former holders of Orca Shares. Any such sale shall be made within ten (10) Business Days or such shorter period as may be required by applicable Law as soon as reasonably practicable after the Orca Effective Time.

(e) Orca Shareholder Definition. As used in this Agreement, “Orca Shareholder” means a registered holder of Orca Shares as shown from time to time on Orca’s register of members.

(f) Topco and Orca shall take all action necessary so that the Topco Shares owned by Orca shall be transferred to Topco, effective as of the Orca Effective Time, for no consideration.

Section 1.5. Effect of the Laguna Merger on Laguna Shares; Laguna Merger Exchange.

(a) As a result of the Laguna Merger and the transactions contemplated by Section 1.2 and without any additional action on the part of Laguna, U.S. Merger Sub or the holders of any capital stock of Laguna or U.S. Merger Sub, at the Laguna Effective Time:

(i) Laguna Merger Consideration. Topco shall allot and issue for each Laguna Share (other than Excluded Laguna Shares) issued and outstanding immediately prior to the Laguna Effective Time, and each such Laguna Share shall automatically be converted into the right to receive, the Laguna Exchange Ratio of fully paid and non-assessable Topco Shares, having the terms set forth in the Topco Charter (such number of Topco Shares, the “Laguna Merger Consideration” and, together with the Orca Scheme Consideration, the “Combination Consideration”).

(ii) Excluded Laguna Shares. Each Laguna Share owned by Laguna, Orca or U.S. Merger Sub, and in each case not held on behalf of third parties (each, an “Excluded Laguna Share”), issued and outstanding immediately prior to the Laguna Effective Time shall automatically be cancelled and shall cease to exist, with no consideration being paid with respect thereto.

(iii) U.S. Merger Sub Shares. Each issued and outstanding share of common stock, par value $0.01 per share, of U.S. Merger Sub issued and outstanding immediately prior to the Laguna Effective Time shall automatically be converted into the right to receive one fully paid and non-assessable share of common stock, par value $0.01, of the Laguna Merger Surviving Corporation, which shares at such time shall comprise the only outstanding shares of capital stock of the Laguna Merger Surviving Corporation.

(b) In accordance with Section 262 of the DGCL, no appraisal rights shall be available to holders of Laguna Shares in connection with the Laguna Merger.

(c) No Fractional Shares. No fractional Topco Shares will be issued in the Laguna Merger to any holder of Laguna Shares.

(d) Unclaimed Funds. Any portion of the Exchange Fund and Fractional Interests Trust that remains unclaimed by the former stockholders of Laguna for 180 days after the Laguna Effective Time shall be delivered to Topco. Any former stockholders of Laguna who have not theretofore complied with Section 1.8 shall thereafter look only to Topco for delivery of any Topco Shares or Fractional Interests Trust of such stockholders and payment of any dividends and other distributions in respect of Topco Shares of such stockholder payable and/or issuable pursuant to this Section 1.5 upon delivery to the Exchange Agent of the applicable certificates formerly representing the Laguna Shares or written instructions for the transfer and cancellation of any entry in the records of Laguna or its transfer agent formerly representing the Laguna Shares, in each case, without any interest thereon. Notwithstanding the foregoing, none of Topco, Orca, Laguna, U.S. Merger Sub, the Exchange Agent or any other Person shall be liable to any former holder of Laguna Shares for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws.

Section 1.6. Effect of the Combinations on Options and Awards.

(a) Effect of the Orca Scheme on Orca Stock Awards.

A-5

(i) Each option to subscribe for Orca Shares (an “Orca Stock Option”) granted under the employee and director stock plans of Orca (the “Orca Stock Plans”), whether vested or unvested, that is outstanding immediately prior to the Orca Effective Time shall cease to represent a right to acquire Orca Shares and shall automatically, without any action on the part of the holders thereof, be converted, at the Orca Effective Time, into (A) an option to purchase Topco Shares (a “Topco Stock Option”) on the same terms and conditions as were applicable under such Orca Stock Option, except as adjusted hereby, (B) with respect to the portion of such Orca Stock Option that is vested as of the Orca Effective Time, a right to receive payment, in cash, equal to the Cash Portion in respect of the Orca Shares that are subject to the vested portion of the Orca Stock Option, and payable pursuant to Section 1.6(a)(vi) below, and (C) with respect to the portion of such Orca Stock Option that is not vested as of the Orca Effective Time, a right to receive payment, in cash, equal to the Cash Portion in respect of the Orca Shares that are subject to the unvested portion of the Orca Stock Option, payable through the payroll system or payroll provider of Topco or its affiliate and subject to applicable withholding, as and when the corresponding portion of the Orca Stock Option vests in accordance with its existing terms (and subject to the same vesting conditions as the existing Orca Stock Option).

The number of Topco Shares covered by each such Topco Equity Right shall be equal to the product (rounded to the nearest whole number) of (x) the number of Laguna Shares subject to the Laguna Equity Right immediately prior to the Laguna Effective Time and (y) the Laguna Exchange Ratio.

Section 1.7. Exchange of Orca Shares.

(a) Exchange Agent. As promptly as practicable following the date hereof, Topco shall appoint a United States bank or trust company or other independent financial institution in the United States reasonably satisfactory to Orca and Laguna (the “Exchange Agent”) to act, among other things, as exchange agent for the Orca Scheme and the Laguna Merger and to deliver the Orca Scheme Consideration (including all cash payable pursuant to Section 1.6) and the Laguna Merger Consideration to former stockholders of Orca and Laguna, respectively. The parties shall enter into an Exchange Agent Agreement with the Exchange Agent, which agreement shall set forth the duties, responsibilities and obligations of the Exchange Agent consistent with the terms of this Agreement.

(b) Orca Shares shall be transferred under the Orca Scheme in exchange for the Orca Scheme Consideration (without interest and after giving effect to any required Tax withholdings as provided in Section 1.10) in accordance with this Agreement, the Orca Scheme Terms, the Orca Scheme Order, the rules and procedures of any depositary or clearing agency through which such shares are held or traded and applicable Law. Prior to the Orca Sanction Hearing, Laguna will irrevocably commit to Topco and, as may be required, the English Court (on terms satisfactory to each of them) to make available to Topco the Cash Portion of the Orca Scheme Consideration, such that on the Closing Date and immediately following the Laguna Effective Time and in full satisfaction of any obligation to pay the Cash Portion to holders of Orca Shares, Laguna shall deposit, or cause to be deposited, in each case on behalf of Topco, with the Exchange Agent, for the benefit of the holders of Orca Shares issued and outstanding immediately prior to the Orca Effective Time, for exchange in accordance with Section 1.6 through the Exchange Agent, sufficient cash to make delivery of the Cash Portion to such holders pursuant to Section 1.4(d).

(c) Each Excluded Orca Share shall immediately following the Orca Effective Time be cancelled and shall cease to exist, with no consideration being paid with respect thereto.

Section 1.8. Exchange of Laguna Certificates and Laguna Book-Entry Shares.

A-8

(a) Exchange Fund. Topco shall deposit with the Exchange Agent, for the benefit of the holders of Laguna Shares (other than the Excluded Laguna Shares), for exchange in accordance with this ARTICLE I, a number of Topco Shares equal to the total number of Topco Shares issuable pursuant to Section 1.5 (the “Exchange Fund”). The Exchange Agent shall, pursuant to irrevocable instructions, deliver Topco Shares contemplated to be issued pursuant to Section 1.5 out of the Exchange Fund.

(b) Exchange Procedures.

(i) Certificates. As soon as practicable after the Laguna Effective Time (and in no event later than five (5) days after the Laguna Effective Time), Topco shall cause the Exchange Agent to mail to each Person that was, immediately prior to the Laguna Effective Time, a holder of record of Laguna Shares (other than the Excluded Laguna Shares) represented by a certificate (each a “Laguna Certificate”): (A) an appropriate and customary letter of transmittal, which shall specify that delivery shall be effected, and risk of loss and title to the Laguna Certificates shall pass, only upon delivery of the Laguna Certificates to the Exchange Agent, and shall otherwise be in such form as Topco, Laguna and the Exchange Agent shall reasonably agree; and (B) instructions for use in effecting the surrender of the Laguna Certificates (or affidavits of loss in lieu of the Laguna Certificates as provided in Section 1.8(e)) in exchange for the Laguna Merger Consideration. Upon surrender of a Laguna Certificate (or affidavit of loss in lieu of the Laguna Certificate as provided in Section 1.8(e)) to the Exchange Agent in accordance with the terms of such letter of transmittal, duly executed, the holder of such Laguna Certificate shall be entitled to receive in exchange therefor the Laguna Merger Consideration (after giving effect to any required Tax withholdings as provided in Section 1.10), and the Laguna Certificate so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any amount payable upon due surrender of the Laguna Certificates. In the event of a transfer of ownership of Laguna Shares that is not registered in the transfer records of Laguna, the Laguna Merger Consideration, upon due surrender of the Laguna Certificate, may be issued to such transferee if the Laguna Certificate formerly representing such Laguna Shares is presented to the Exchange Agent, accompanied by all documents reasonably required by Topco to evidence and effect such transfer and to evidence that any applicable stock transfer Taxes have been paid or are not applicable. Until surrendered as contemplated hereby, each Laguna Certificate shall be deemed at any time after the Laguna Effective Time to represent only the right to receive the Laguna Merger Consideration (in each case, without interest and after giving effect to any required Tax withholdings as provided in Section 1.10) as contemplated by this Agreement. For the purposes of this Agreement, the term “Person” means any individual, corporation (including not-for-profit), general or limited partnership, limited liability company, joint venture, estate, trust, association, organization, Governmental Entity or Self-Regulatory Organization or other entity of any kind or nature. “Self-Regulatory Organization” means any United States or non-United States commission, board, agency or body that is not a Governmental Entity but is charged with the supervision or regulation of brokers, dealers, securities underwriting or trading, stock exchanges, commodities exchanges, electronic communication networks, insurance companies or agents, investment companies or investment advisers, including Nasdaq Global Select Market (“Nasdaq”).

(ii) Laguna Book-Entry Interests. Notwithstanding anything to the contrary contained in this Agreement, no holder of rights to an entry in the records of Laguna or its transfer agent representing Laguna Shares (the “Laguna Book-Entry Interests”) shall be required to deliver a Laguna Certificate or, in the case of holders of Laguna Book-Entry Interests held through The Depositary Trust Company, an executed letter of transmittal to the Exchange Agent to receive the Laguna Merger Consideration that such holder is entitled to receive pursuant to this Section 1.8. In lieu thereof, each holder of record of one or more Laguna Book-Entry Interests held through The Depositary Trust Company whose Laguna Shares were converted into the right to receive the Laguna Merger Consideration shall automatically upon the Laguna Effective Time be entitled to receive, and Topco shall cause the Exchange Agent to pay and deliver as promptly as practicable after the Laguna Effective Time, in respect of each such Laguna Book-Entry Interest the Laguna Merger Consideration, without interest and after giving effect to any required Tax withholdings as provided in Section 1.10), and such Laguna Book-Entry Interests of such holder shall forthwith be cancelled. As soon as practicable after the Laguna Effective Time (and in no event later than five (5) days after the Laguna Effective Time), Topco shall cause the Exchange Agent to mail to each Person that was, immediately prior to the Laguna Effective Time, a holder of record of Laguna Book-Entry Interests not held through The Depositary Trust Company: (A) an appropriate and customary letter of transmittal, which shall be in such form as Topco, Laguna and the Exchange Agent shall reasonably agree; and (B) instructions for returning such letter of transmittal in exchange for the Laguna Merger Consideration. Upon delivery of such letter of transmittal to the Exchange Agent, in accordance with the terms of such letter of transmittal, duly executed, the holder of such Laguna Book-Entry Interests shall be entitled to receive in exchange therefor the Laguna Merger Consideration (after giving effect to any required Tax withholdings as provided in Section 1.10), and such Laguna Book-Entry Interests so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any amount payable upon due surrender of Laguna Book-Entry Interests. The Laguna

A-9

Merger Consideration with respect to Laguna Book-Entry Interests shall only be made to the Person in whose name such Laguna Book-Entry Interests are registered. Until paid or surrendered as contemplated hereby, each Laguna Book-Entry Interest shall be deemed at any time after the Laguna Effective Time to represent only the right to receive the Laguna Merger Consideration as contemplated by this Agreement.

(c) Transfer Books; No Further Ownership Rights in Shares. At the Laguna Effective Time, the stock transfer books of Laguna shall be closed and thereafter there shall be no further registration of transfers of Laguna Shares on the records of Laguna. From and after the Laguna Effective Time, the holders of Laguna Certificates and Laguna Book-Entry Interests representing Laguna Shares outstanding immediately prior to the Laguna Effective Time shall cease to have any rights with respect to such shares except as otherwise provided for herein or by applicable Law, subject, however, to the Laguna Merger Surviving Corporation’s obligation to pay any dividends or make any other distributions with a record date prior to the Laguna Effective Time that may have been declared or made by Laguna on such Laguna Shares not in violation of the terms of this Agreement or prior to the date of this Agreement and which remain unpaid at the Laguna Effective Time. If, after the Laguna Effective Time, Laguna Certificates representing Laguna Shares are presented to Topco for any reason, they shall be cancelled and exchanged for the Laguna Merger Consideration as provided in this Agreement.

(d) Termination of Fund; Abandoned Property; No Liability. At any time following one (1) year after the Scheme Effective Date, Topco shall be entitled to require the Exchange Agent to deliver to it, or its nominee, any Topco Shares remaining in the Exchange Fund made available to the Exchange Agent and not delivered to holders of Laguna Certificates or Laguna Book-Entry Interests, and thereafter such holders shall be entitled to look only to Topco (subject to abandoned property, escheat or other similar Laws) as general creditors thereof with respect to the Laguna Merger Consideration payable upon due surrender of their Laguna Certificates or Laguna Book-Entry Interests and compliance with the procedures in Section 1.8. If, prior to six (6) years after the Scheme Effective Date (or otherwise immediately prior to such time on which any payment in respect hereof would escheat to or become the property of any Governmental Entity pursuant to any applicable abandoned property, escheat or similar Laws), any holder of Laguna Certificates or Laguna Book-Entry Interests has not complied with the procedures in Section 1.8 to receive the Laguna Merger Consideration to which such holder would otherwise be entitled, the Laguna Merger Consideration to which such holder would otherwise be entitled in respect of such Laguna Certificates or Laguna Book-Entry Interests shall, to the extent permitted by applicable Law, become the property of Topco, free and clear of all claims or interest of any Person previously entitled thereto. Notwithstanding the foregoing, neither Topco nor the Exchange Agent shall be liable to any holder of a Laguna Certificate or Laguna Book-Entry Interests for Laguna Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(e) Lost, Stolen or Destroyed Certificates. In the event that any Laguna Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Laguna Certificates, upon the making of an affidavit of that fact by the holder thereof, the Laguna Merger Consideration payable in respect thereof pursuant to Section 1.5 hereof (after giving effect to any required Tax withholdings as provided in Section 1.10); provided, however, that Topco or the Exchange Agent may, in its reasonable discretion and as a condition precedent to the payment of the Laguna Merger Consideration, require the owners of such lost, stolen or destroyed Laguna Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Topco or the Exchange Agent with respect to the Laguna Certificates alleged to have been lost, stolen or destroyed.

(f) Distributions with Respect to Unexchanged Topco Shares. No dividends or other distributions declared or made after the Laguna Effective Time with respect to Topco Shares with a record date after the Laguna Effective Time shall be paid to the holder of any unsurrendered Laguna Certificate or Laguna Book-Entry Interest with respect to Topco Shares represented thereby, unless and until the holder of such Laguna Certificate or Laguna Book-Entry Interest shall surrender such Laguna Certificate or Laguna Book-Entry Interest. Subject to the effect of escheat, Tax or other applicable Laws, following surrender of any such Laguna Certificate, there shall be paid by Topco to the holder of the certificates representing Topco Shares issued in exchange therefor, without interest, (i) promptly, the amount of dividends or other distributions with a record date after the Laguna Effective Time theretofore paid with respect to such Topco Shares and (ii) at the appropriate payment date, the amount of dividends or other distributions, with a record date after the Laguna Effective Time but prior to surrender and a payment date occurring after surrender, payable with respect to such Topco Shares.

Section 1.9. Contributions. Immediately following, and as part of a plan that includes, the Combinations, Topco shall transfer (the “First Contribution”) 100% of the depositary interests in the issued and outstanding Orca Shares held by the DR Nominee and the Deferred Shares to U.S. Holdco Sub as a contribution to capital and, at least two days following the

A-10

First Contribution, U.S. Holdco Sub will transfer (the “Second Contribution” and, collectively with the First Contribution, the “Contributions”), 100% of the depositary interests in the issued and outstanding Orca Shares held by U.S. Holdco Sub and the Deferred Shares to U.S. Holdco Sub 2, a newly formed Delaware corporation wholly owned by U.S. Holdco Sub.

Section 1.10. Withholding. Each of Laguna, Orca, Topco, the Laguna Merger Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from any consideration payable pursuant to this Agreement or the Orca Scheme such amounts, if any, as it is required to deduct and withhold with respect to the making of such payment under the Code and the rules and regulations promulgated thereunder, or any provision of state, local or non-U.S. Tax Law. To the extent that amounts are so withheld by Laguna, Orca, Topco, the Laguna Merger Surviving Corporation or the Exchange Agent, as the case may be and paid over to the appropriate Tax authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the recipient in respect of which such deduction and withholding was made. All parties to this Agreement shall cooperate in coordinating the deduction and withholding of any Tax required to be deducted and withheld under applicable Tax Law.

Section 1.11. Merger Consideration Adjustment. In the event that between the date of this Agreement and the Laguna Effective Time, the outstanding Orca Shares or Laguna Shares or securities convertible into, or exercisable or exchangeable for Orca Shares or Laguna Shares shall have been changed into a different number of shares or a different class, by reason of any stock dividend or distribution, subdivision, reclassification, recapitalization, split, combination, consolidation or exchange of shares, or any similar event shall have occurred, then any number or amount contained herein (including any exchange ratio) which is based upon the number of Orca Shares or Laguna Shares, as the case may be, will be appropriately adjusted to provide to the stockholders of both Orca and Laguna the same economic effect as contemplated by this Agreement prior to such event.

Section 1.12. O rca and Topco Actions Prior to and at Closing.

(a) On or prior to Closing, Orca shall procure that a meeting of the Orca Board is held at which resolutions are passed (conditional upon the delivery of the Orca Scheme Order to the Registrar and effective as at the Orca Effective Time) approving: (i) the transfer to (or, as applicable, within) the DR Nominee of the Orca Shares provided to be transferred under the Orca Scheme and the registration as a member of such person(s) in accordance with the Orca Scheme in respect of such Orca Shares, with such Orca Shares to be subsequently transferred by the DR Nominee to Topco, (ii) the removal or resignation of the directors of Orca, (iii) the appointment of such persons as Orca shall determine (acting reasonably) as the directors of Orca and (iv) the (A) transfers to (a) Topco at the Orca Effective Time; (b) to U.S. Holdco Sub at the time of the First Contribution and (c) to U.S. Holdco Sub 2 at the time of the Second Contribution, each for nil consideration and (B) subsequent repurchase by Orca (no earlier than one day after the Orca Conversion) for nil consideration, and subsequent cancellation, of the 50,001 deferred shares of £1.00 each in the share capital of Orca (the “Deferred Shares”), and directing Orca’s officers to take such actions within their control to effect such transfers, repurchase and cancellation.

“Intervening Event” means any material event or development or material change in circumstances first occurring after the date of this Agreement and prior to, in the case of Laguna, receipt by Laguna of the Laguna Requisite Vote and, in the case of Orca, receipt by Orca of the Orca Requisite Vote, to the extent that such event, development or change in circumstances was not reasonably foreseeable as of or prior to the date of this Agreement; provided, however, that in no event shall the following events, developments or changes in circumstances constitute an Intervening Event: (A) the receipt, existence or terms of an Acquisition Proposal or any matter relating thereto or consequence thereof, or (B) changes in the market price or trading volume of Orca Shares or Laguna Shares or the fact that a party meets or exceeds internal or published projections, forecasts or revenue or earnings predictions for any period; provided, however, that the underlying causes of such change or fact shall not be excluded by this clause (B).

(e) The Laguna Board shall not be entitled to effect a Change in Laguna Recommendation unless it is expressly permitted to do so under Section 5.2(d) and (i) Laguna has not breached this Section 5.2(e) in any material respect, (ii) Laguna has provided Orca with a written notice (the “Laguna Change in Recommendation Notice”) that Laguna intends to take such action, which notice includes, as applicable, (x) an unredacted copy of the Superior Proposal that is the basis of such action (including the identity of the third party making the Superior Proposal and any debt financing materials related thereto, if any) and written notice of the material terms of the Superior Proposal, or (y) a reasonably detailed summary of the Intervening Event that is the basis of such action, (iii) during the five (5) Business Day period following Orca’s receipt of the Laguna Change in Recommendation Notice, Laguna shall, and shall cause its Representatives to, negotiate with Orca in good faith (to the extent Orca desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Superior Proposal ceases to constitute a Superior Proposal or, with respect to an Intervening Event, as would permit the Laguna Board (consistent with its fiduciary duties under applicable Law) to not make a Change in Laguna Recommendation; and (iv) following the end of the five (5) Business Day period, the Laguna Board shall have determined in good faith, after consultation with its financial and outside legal advisors, taking into account any changes to this Agreement proposed in writing by Orca in response to the Laguna Change in Recommendation Notice or otherwise, that the Superior Proposal giving rise to the Laguna Change in Recommendation Notice continues to constitute a Superior Proposal or, as applicable, with respect to the Intervening Event, that its fiduciary duties under applicable Law continue to require it to make such an Change in Laguna Recommendation. Any amendment to the financial terms or any other material amendment of such Superior Proposal or any material change to the facts and circumstances relating to an Intervening Event, as applicable, shall require a new Laguna Change in Recommendation Notice and Laguna shall be required to comply again with the requirements of this Section 5.2(e); provided, however, that for purposes of this sentence, references to the five (5) Business Day period above shall be deemed to be references to a three (3) Business Day period.

Any amendment to the financial terms or any other material amendment of such Superior Proposal or any material change to the facts and circumstances relating to an Intervening Event, as applicable, shall require a new Orca Change in Recommendation Notice and Orca shall be required to

A-38

comply again with the requirements of this Section 5.2(e); provided, however, that for purposes of this sentence, references to the five (5) Business Day period above shall be deemed to be references to a three (3) Business Day period.

(g) Each of Laguna and Orca agrees that it will, and will use reasonable best efforts to cause its Representatives and its Subsidiaries and such Subsidiaries’ Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations existing as of the date of this Agreement with any Persons conducted heretofore with respect to any Acquisition Proposal (or that could reasonably be expected to lead to an Acquisition Proposal), and request that any such Person promptly return and destroy (and confirm destruction of) all non-public information. Each of Laguna and Orca agrees that it will use reasonable best efforts to promptly inform its Representatives of the obligations undertaken in this Section 5.2. Nothing in this Section 5.2 shall (x) permit Laguna or Orca to terminate this Agreement (except as specifically provided in Article VII hereof), or (y) affect any other obligation of Laguna or Orca under this Agreement, except as otherwise expressly set forth in this Agreement.

(i) As promptly as practicable after the date of this Agreement (having regard to the timing requirements of the Registration Statement), the parties shall (A) as further detailed and subject to the specific obligations of the respective parties set out in this Section 5.3, prepare or cause to be prepared a scheme circular (the “Orca Scheme Document”) containing, among other things, a letter from the Orca chairman, (subject to (e)) the Orca Recommendation, full terms and conditions of the Orca Scheme and other relevant terms and conditions of the Proposals, a timetable of events relating to the Orca Scheme (the “Timetable”), a summary of key implications of the Orca Scheme, a scheme of arrangement, an explanatory statement and notices to convene the Orca Shareholder Meetings (together with any revisions, amendments or supplements to such document, the “Orca Scheme Terms”) in accordance with English Law and the DGCL, as applicable, together with preparation of forms of proxy for each of the Orca Shareholder Meetings, and where the context requires, preparation of documents to be put on display, court document(s), meeting advertisements or other documents reasonably required in connection with the Orca Scheme; and (B) apply for such written confirmation from Her Majesty’s Revenue and Customs (“HMRC”) that neither the Orca Scheme Order nor any instrument of transfer transferring the Orca Shares held within The Depository Trust Company (“DTC”) or the Orca Depositary to a DR Nominee is subject to United Kingdom stamp duty or Stamp Duty Reserve Tax (“SDRT”) and that the only instrument or agreement subject to UK stamp duty or SDRT will be the stock transfer form(s), if any, which transfer Orca Shares not held within DTC or the Orca Depositary to Topco (or its nominee). For the avoidance of doubt, the failure to obtain any confirmations to be applied for pursuant this Section 5.3 shall not by itself constitute any breach of obligations of any party under this Agreement.

(ii) Orca shall be responsible for preparation of the Orca Scheme Terms, in each case, to the standard that is required pursuant to the UK Scheme Regulations to the extent customary or legally required for transactions of the type of the Orca Scheme, and to satisfy any other requirements that may reasonably be expected by, or as directed by, the English Court.

(iii) Orca shall ensure that the Orca Scheme Document includes customary terms relating to the transfer of shares subject to the Orca Scheme free from all encumbrances and relating to the form of transfer including without limitation the following terms: (A) on and with effect from the Scheme Effective Date, the DR Nominee on behalf of Topco shall acquire all of the Orca Scheme Shares, fully paid up with full title guarantee free from all encumbrances and with all rights attaching to them at the Orca Effective Time, including the right to receive all dividends and other distributions declared, made or paid after the Orca Effective Time; and (B) for the purposes of the Acquisition Proposal, the Orca Scheme Shares shall be transferred to the DR Nominee on behalf of Topco and such transfer shall be effected by means of a form of transfer or other instrument of transfer and to give effect to such transfers any director of the Orca may be appointed by

A-39

virtue of the Orca Scheme as attorney and/or agent and/or otherwise and shall be authorized pursuant to the Orca Scheme as such attorney and/or agent and/or otherwise on behalf of the relevant holder of Orca Scheme Shares to execute and deliver as transferor a form of transfer or other instrument or instruction of transfer in a form. In this Clause 5.3(a)(iii), references to Orca Scheme Shares being transferred to or acquired by the DR Nominee on behalf of Topco shall, to the extent that such Orca Scheme Shares are already held by the DR Nominee at the Orca Effective Time, be construed as references to the DR Nominee ceasing to hold such Orca Scheme Shares on behalf of any other person and commencing holding such Orca Scheme Shares on behalf of Topco.

(iv) Orca shall procure that the Directors of Orca accept responsibility for all the information in the Orca Scheme Document (and any other document required by applicable Law to be published in connection with the Orca Scheme) relating to themselves (and members of their immediate families, related trusts and persons connected with them), Topco, the Orca Group, any statements of opinion, belief or expectation of the directors of Orca in relation to the Acquisition Proposal or the Orca Group and any other information in the Orca Scheme Document for which they are required by applicable Law to accept responsibility.

(v) Laguna shall procure that the Directors of Laguna accept responsibility for all the information in the Orca Scheme Document (and any other document required by applicable Law to be published in connection with the Orca Scheme) relating to themselves (and members of their immediate families, related trusts and persons connected with them), the Laguna Group, any statements of opinion, belief or expectation of the directors of Laguna in relation to the Acquisition Proposal or the Laguna Group and any other information in the Orca Scheme Document for which they are required by applicable Law to accept responsibility.

(vi) Laguna and Topco shall afford all such cooperation and assistance as may reasonably be requested of it by Orca in respect of the preparation and verification of any document required for the implementation of the Orca Scheme, including the provision to Orca of such information and confirmations relating to it, its Subsidiaries and any of its or their respective directors or employees as Orca may reasonably request (including for the purposes of preparing the Orca Scheme Terms and all material ancillary documents in connection thereto) and to do so in a timely manner. Orca agrees that it shall take reasonable steps to consult with Laguna and its professional advisers as to the form and content of the Orca Scheme Terms and provide Laguna with drafts of the Orca Scheme Terms. Orca shall afford Laguna and its professional advisers reasonable opportunity to consider, review and provide comments on drafts of the Orca Scheme Terms. Laguna shall review and provide comments (if any) in a reasonably timely manner on all such documentation submitted to it and Orca shall consider all comments proposed by Laguna and its professional advisers in good faith. To the extent of any inconsistency between this Agreement and the Orca Scheme Terms, the Orca Scheme Terms shall be amended or modified so as to conform to this Agreement, subject to mandatory provisions of English Law and DGCL, as applicable. The parties will, as promptly as reasonably practicable, notify each other if they become aware of any matter which would reasonably be expected to materially delay or prevent fulfilment of any of the steps in the Timetable including, filing and/or circulation of the Orca Scheme Document or the Orca Scheme Order. As promptly as practicable following the finalization of the Orca Scheme Terms, and in accordance with all applicable Law, the Orca Board and the Topco Board, as well as Orca in its capacity as the sole stockholder of Topco, shall approve the Orca Scheme Terms and the transactions contemplated thereby.

(vii) As promptly thereafter as is practicable and in accordance with the Timetable, Orca shall apply to the Court to schedule a hearing of the English Court (the “Scheme Convening Hearing” (including, where the context requires, any adjournment thereof)) at which the English Court will be invited to: (A) provide directions in connection with the Orca Scheme (including any issue which may arise in connection with the constitution of meetings of members, creditors or other interested persons) and Orca Scheme Document; and (B) grant an order (the “Scheme Directions Order”) for the convening of the meeting of the Orca Shareholders in accordance with the UK Scheme Regulations (to approve the Orca Scheme Terms (the “Orca Scheme Meeting”)), and shall make all necessary applications, prepare and file such documents (including advertising or otherwise providing due notice of the Scheme Convening Hearing to any person affected by the Orca Scheme in accordance with Court’s Practice Statement (Companies: Schemes of Arrangement under Part 26 and Part 26A of the Companies Act 2006) dated 26 June 2020). Orca shall apply at the Scheme Convening Hearing for permission to convene the Orca Court Meeting and shall make all necessary applications, prepare and file such documents and take such steps as may be necessary to facilitate and convene the Orca Court Meeting and the Orca General Meeting including without limitation, filing a notice of the Orca Scheme Meeting to be published in the London Gazette (the “Orca Scheme Meeting Publication”). Orca shall circulate to the holders of Orca Scheme Shares, relevant Orca Stock Option and Orca Equity Rights Holders the Orca Scheme Document, together with relevant forms of proxy and such other information, documents, circulars, forms and notices (as the case may be) as are or may be required under the UK Scheme Regulations, as the Court may approve and/or

A-40

direct from time to time in connection with the due implementation of the Orca Scheme and such other information, circulars, forms or notices (as the case may be) as the parties agree in writing.

(viii) Following the Orca Scheme Meeting Publication, Orca shall promptly notify Laguna upon receipt of notice of any pending or threatened opposition rights proceeding initiated by any creditors, holders of bonds (obligations), whether or not redeemable or convertible, or warrants (collectively, “Creditors”) of Orca pursuant to English Law. Such notice shall describe in reasonable detail the nature of such opposition rights proceeding. With respect to any such opposition rights proceeding, Section 5.6 shall apply mutatis mutandis.

(ix) Orca shall, convene, hold and transact the relevant business at each of the Orca Shareholder Meetings at the time and date specified in the Scheme Document (or as soon as practicable thereafter) and propose the resolutions set out in the notices of those meetings (as appropriate) without amendments. Orca shall (and shall procure that any relevant member of the Orca Group shall) once approved by Laguna (pursuant to the terms set out in this Section 5.3(a)) and the English Court, not seek (by application to the English Court or otherwise) to: (A) revise the Scheme Document; (B) amend the terms of the Acquisition Proposal; or (C) (unless required by the Court or subject to Section 5.3(f)) adjourn the Orca Shareholder Meetings, in each case, without the prior written consent of Laguna (such consent not to be unreasonably withheld, delayed or conditioned). Further, Orca shall not (unless required by the English Court) agree to, or apply to the English Court for, an extension of time in connection with, or to any variation, amendment, withdrawal or non-enforcement (in whole or in part) of, the Orca Scheme without the prior written consent of Laguna (such consent not to be unreasonably withheld, delayed or conditioned). Following each of the Orca Shareholder Meetings and assuming the necessary resolutions are passed by the requisite majorities, subject to and as soon as reasonably practicable (in accordance with the Timetable), make all necessary applications, prepare and file such documents and take all necessary steps to seek the sanction of the English Court to the Orca Scheme at the Scheme Sanction Hearing. Orca shall attend each of the Orca Scheme Meeting and the Orca General Meeting and, by representation of the Scheme Counsel, shall attend the Scheme Convening Hearing and the Orca Sanction Hearing.

(x) Promptly following sanction of the Orca Scheme and receipt of the Orca Scheme Order and in any event no later than one Business Day after the Orca Scheme Order issued by the English Court being available for collection and/or registration, Orca shall deliver to the Registrar for filing by him or her and/or registration as the case may be originals and office copies of the Orca Scheme Order and any other necessary documents to be filed with the Registrar for the purpose of causing the Orca Scheme to become effective in compliance with the UK Scheme Regulations and to give effect to the provisions of the Orca Scheme. Orca shall (and shall procure that relevant members of the Orca Group shall) comply with the Scheme Directions Order and the Orca Scheme Order.

(xi) For the purposes of this Agreement, “Orca Scheme Shares” shall mean shares of Orca: (A) in issue at the date of the Orca Scheme Document; (B) issued after the date of the Orca Scheme Document and before the date specified in the Orca Scheme Document by reference to which entitlement to vote at the Orca Scheme Meeting will be determined in accordance with the UK Scheme Regulations (the “Voting Record Time”); and (C) issued at or after the Voting Record Time and before the Scheme Record Time, either on terms that the original or any subsequent holders of such shares are to be bound the by Orca Scheme or in respect of which their holders are, or shall have agreed in writing to be, bound by the Orca Scheme.

(b) As promptly as practicable after the date of this Agreement, the parties shall prepare and Topco shall file with the SEC, a registration statement on Form S-4 (together with any supplements or amendments thereto, the “Registration Statement”) to register the offer and exchange of Topco Shares, as applicable, pursuant to the Combinations. The Registration Statement will include the scheme circular with respect to the Orca Scheme Terms and a joint proxy statement/prospectus (the “Proxy Statement/Prospectus”) to be used for (i) the Laguna Stockholders’ Meeting to approve and adopt this Agreement and the Laguna Merger, (ii) the Orca Shareholder Meetings to approve and adopt this Agreement and the Orca Scheme and (iii) the issuance of Topco Shares in the Combinations. Topco, Orca and Laguna each shall use reasonable best efforts to cause the Registration Statement to become effective as promptly as practicable following such filing (including by responding to comments of the SEC), and shall also use its reasonable best efforts to satisfy prior to the effective date of the Registration Statement any applicable United States, English, foreign or state securities Laws in connection with the issuance of Topco Shares pursuant to the Combinations. After the execution of this Agreement and as promptly as reasonably practicable in accordance with applicable Law: the parties shall prepare and Topco shall file with Nasdaq a listing application (the “Nasdaq Listing Application”) for the listing of Topco Shares on Nasdaq. Each party and its Subsidiaries shall prepare and furnish all information (including any required financial statements) concerning itself as may reasonably be requested in

A-41

connection with such actions and the preparation of the Registration Statement and the Nasdaq Listing Application, provided that no party shall use any such information for any other purpose without the prior written consent of the providing party (which consent shall not be unreasonably withheld, conditioned or delayed) or if doing so would violate or cause a violation of United States, English or other applicable securities Laws. Each of Laguna and Orca authorizes Topco to utilize in the Registration Statement and in all such filed materials the information concerning Laguna and its Subsidiaries and Orca and its Subsidiaries furnished by each of Laguna and Orca, respectively. Each party shall provide the other parties with a reasonable opportunity to review the Registration Statement, the Proxy Statement/Prospectus and Nasdaq Listing Application, and any amendment or supplement thereto (which comments shall be reasonably considered by the party making such filing) prior to their filing. No filing of, or amendment or supplement to, such document shall be made by Topco, Orca or Laguna, without the prior consent of Orca and Laguna, as applicable (which consent shall not be unreasonably withheld, delayed or conditioned). Subject to applicable Law, the parties agree that the information relating to the parties and their respective businesses included in the Registration Statement and the Nasdaq Listing Application shall be identical in terms of content to the greatest extent practicable and necessary. The parties agree to correct promptly any information provided by it for use in the Registration Statement and the Nasdaq Listing Application if and to the extent that such information shall have become false or misleading in any material respect or as otherwise required by applicable Law. Topco shall promptly advise Orca and Laguna of the time of effectiveness of the Registration Statement, the issuance of any stop order relating thereto or the suspension of the qualification of Topco Shares for offering or sale in any jurisdiction, and each of the parties shall use its reasonable best efforts to have any such stop order or suspension lifted, reversed or otherwise terminated. The parties shall notify each other promptly of the receipt of any comments from the SEC or its staff or any comments from any other Governmental Entity and of any request by the SEC or its staff or any request by any other Governmental Entity for amendments or supplements to the Registration Statement, the Proxy Statement/Prospectus or Nasdaq Listing Application, or for additional information relating thereto, and will supply each other with copies of all correspondence between Laguna, Orca or Topco, as applicable, or any of their respective Representatives, and the SEC or its staff or any other Governmental Entity with respect to the foregoing documents and applications.

(c) Each of the parties shall also take any other action (other than qualifying to do business in any jurisdiction in which it is not now so qualified) required to be taken under the Securities Act of 1933, as amended, and the rules and regulations of the SEC promulgated thereunder (the “Securities Act”), the Exchange Act, any applicable English or other non-United States securities Laws or any applicable state securities or “blue sky” laws and the rules and regulations thereunder, in connection with the transactions contemplated by this Agreement and the issuance and Nasdaq listing of Topco Shares.

(d) Laguna will take, in accordance with applicable Law, the applicable rules and regulations of the SEC and Nasdaq and the Laguna Organizational Documents, all action necessary to convene a meeting of its stockholders to adopt and approve this Agreement, the Laguna Merger and the ancillary matters contemplated by this Agreement (the “Laguna Stockholders’ Meeting”) as promptly as practicable after the later of (x) the expiration of any Creditor rights opposition period following the Orca Scheme Terms Publication under English Law and (y) the date the Registration Statement is declared effective. The Laguna Board shall make the Laguna Recommendation and include the Laguna Recommendation in the Proxy Statement/Prospectus. Laguna shall, unless there has been a Change in Laguna Recommendation as permitted by this Agreement, use all lawful efforts to solicit from its stockholders proxies in favor of the adoption of this Agreement and the transactions contemplated hereby and to take all other action reasonably necessary or advisable to secure Laguna’s stockholders’ approval thereof. In the event that on or subsequent to the date hereof and prior to the Laguna Stockholders’ Meeting (including any adjournment thereof), the Laguna Board determines either to make no recommendation for the Laguna Merger, or to withdraw, modify or qualify its recommendation for the Laguna Merger in a manner that is adverse to Orca (including by failing to recommend against any Acquisition Proposal structured as a tender or exchange offer (or any material modification thereto) within ten (10) Business Days after commencement of such offer (or such material modification)) (such determination not to make a recommendation or any such withdrawal, modification or qualification, a “Change in Laguna Recommendation”), which Change in Laguna Recommendation shall be made only in accordance with Section 5.2(d), then Orca shall have a right to terminate this Agreement in accordance with Section 7.4(a). Any Change in Laguna Recommendation shall not limit or modify the obligation of Laguna to present this Agreement for adoption at the Laguna Stockholders’ Meeting pursuant to this Section 5.3(d), and, if this Agreement is not otherwise terminated by either Laguna or Orca in accordance with the terms hereof, this Agreement and the transactions contemplated hereby shall be submitted to the stockholders of Laguna at the Laguna Stockholders’ Meeting for the purpose of obtaining the Laguna Requisite Vote; provided, that, the foregoing obligation shall not apply in the event of a Change in Laguna Recommendation made in accordance with Section 5.2(d) in response to a Superior Proposal that (i) includes only cash consideration and (ii) is

A-42

fully financed and does not include any financing condition (including any financing contingency to the right of Laguna to seek specific performance) (a “Laguna All Cash Superior Proposal”).

(e) Orca will take, in accordance with applicable Law, the applicable rules and regulations of the SEC and Nasdaq and the Orca Organizational Documents, all action necessary to convene the Orca Scheme Meeting and an Orca-convened general meeting of Orca Shareholders to resolve and approve the Orca Board implementing the Orca Scheme and adopt the Orca Articles of Association in the form set out in Exhibit A and the ancillary matters contemplated by this Agreement (the “Orca General Meeting” and, together with the Orca Scheme Meeting, the “Orca Shareholder Meetings”) as promptly as practicable after the later of (x) the expiration of any Creditor rights opposition period following the Orca Scheme Terms Publication under English Law and (y) the date the Registration Statement is declared effective. The Orca Board shall make the Orca Recommendation and include the Orca Recommendation in the Proxy Statement/Prospectus. Orca shall, unless there has been a Change in Orca Recommendation as permitted by this Agreement, use all lawful efforts to solicit from the Orca Shareholders proxies in favor of the approval of the Orca Scheme Terms and the transactions contemplated hereby and to take all other action reasonably necessary or advisable to secure Orca’s stockholders’ approval thereof. Without limitation to the foregoing, Orca shall undertake all reasonable steps to support and facilitate the execution and implementation of irrevocable undertakings and/or support agreements by Carlyle in relation to the Orca Scheme and securing the Orca Requisite Vote including supporting or facilitating any steps taken by Carlyle (whether under its respective agreements or otherwise) to procure the transfer of legal title in any of its beneficial interests in Orca Scheme Shares in order to be able to vote directly in its own name in favor of the Orca Requisite Vote. In the event that on or subsequent to the date hereof and prior to the Orca Shareholder Meetings (including any adjournment thereof), the Orca Board determines either to make no recommendation for the Orca Scheme, or to withdraw, modify or qualify its recommendation for the Orca Scheme in a manner that is adverse to Laguna (including by failing to recommend against any Acquisition Proposal structured as a tender or exchange offer (or any material modification thereto) within ten (10) Business Days after commencement of such offer (or such material modification)) (such determination not to make a recommendation or any such withdrawal, modification or qualification, a “Change in Orca Recommendation”), which Change in Orca Recommendation shall be made only in accordance with Section 5.2(d), then Laguna shall have a right to terminate this Agreement in accordance with Section 7.3(a). Any Change in Orca Recommendation shall not limit or modify the obligation of Orca to present the Orca Scheme for approval at the Orca Scheme Meeting or the Orca General Meeting pursuant to this Section 5.3(e), and, if this Agreement is not otherwise terminated by either Laguna or Orca in accordance with the terms hereof, this Agreement, the Orca Scheme Terms and the transactions contemplated hereby shall be submitted to the stockholders. Any Change in Orca Recommendation shall not limit or modify the obligation of Orca to present the Orca Scheme for approval at the Orca Scheme Meeting or the Orca General Meeting pursuant to this Section 5.3(e), and, if this Agreement is not otherwise terminated by either Laguna or Orca in accordance with the terms hereof, this Agreement, the Orca Scheme Terms and the transactions contemplated hereby shall be submitted to the stockholders of Orca at the Orca Shareholder Meetings for the purpose of obtaining the Orca Requisite Vote; provided, that, the foregoing obligation shall not apply in the event of a Change in Orca Recommendation made in accordance with Section 5.2(d) in response to a Superior Proposal that (i) includes only cash consideration and (ii) is fully financed and does not include any financing condition (including any financing contingency to the right of Orca to seek specific performance) (an “Orca All Cash Superior Proposal”).

(f) In accordance with the Timetable and subject to any directions or requirements of the English Court, Laguna and Orca shall each use their reasonable best efforts to cause the Laguna Stockholders’ Meeting and the Orca Shareholder Meetings to be held on the same date. Notwithstanding the foregoing, (i) after the Laguna Stockholders’ Meeting has been convened, Laguna shall, upon the request of Orca (and Laguna may, if Orca does not make such request) adjourn the Laguna Stockholders’ Meeting on one or more occasions (A) if required by Law or (B) to the extent necessary to solicit additional proxies in order to obtain the Laguna Requisite Vote, for such time period as determined by Orca (or, if Orca does not make such request, as determined by Laguna) and (ii) after the Orca Shareholder Meetings have been convened, Orca shall, upon the request of Laguna (and Orca may, if Laguna does not make such request) adjourn the Orca Shareholder Meetings on one or more occasions (A) if required by Law or (B) to the extent necessary to solicit additional proxies in order to obtain the Orca Requisite Vote, for such time period as determined by Laguna (or, if Laguna does not make such request, as determined by Orca); provided, however that, in each case, (x) such adjournment shall not exceed fifteen (15) days for each such adjournment, (y) the applicable stockholders’ meeting shall not be adjourned without the written approval of both Laguna and Orca by more than thirty (30) days in the aggregate from the date on which the Laguna Stockholders’ Meeting or Orca Shareholder Meetings, as applicable, was originally convened, and (z) no such adjournment shall be permitted if Laguna or Orca, as applicable, shall have received at the applicable Stockholders’ Meeting an aggregate number of proxies necessary to obtain the Laguna Requisite Vote or the Orca Requisite Vote, as applicable, which have not been withdrawn, such that the

A-43

condition in Section 6.1(a) would be satisfied (with respect to Laguna or Orca, as applicable) if a vote were taken at the applicable Stockholders’ Meeting.

Section 5.4. Reasonable Best Efforts; Regulatory Filings and Other Actions.

(a) Reasonable Best Efforts; Regulatory Filings. The parties shall cooperate with each other and use (and shall cause their respective Subsidiaries to use) their respective reasonable best efforts to take or cause to be taken all actions, and do or cause to be done all things, necessary, proper or advisable under this Agreement and applicable Laws to consummate and make effective the Combinations and the other transactions contemplated by this Agreement as promptly as practicable, including (i) preparing and filing all documentation to effect all necessary Filings as promptly as practicable (and with respect to Filings pursuant to the HSR Act, no later than 10 Business Days after the date of this Agreement) and obtaining as promptly as practicable all Approvals (including all Antitrust Approvals) necessary or advisable to be obtained from any Person and/or any Governmental Entity or any Self-Regulatory Organization in order to consummate the transactions contemplated by this Agreement, (ii) using their reasonable best efforts to resolve any objections as may be asserted with respect to the transactions contemplated by this Agreement under any Laws, including defending and contesting (through litigation on the merits and any appeals) any Proceedings, whether judicial or administrative or otherwise, challenging this Agreement or the consummation of the transactions contemplated by this Agreement, including seeking to have any Order entered by any court or other Governmental Entity vacated or reversed, and (iii) executing and delivering any additional instruments necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement pursuant to its terms and conditions.

(b) Obligations Relating to Filings. Without limiting the foregoing, the parties shall exercise their respective best efforts to (i) obtain termination or expiration of the waiting period (and any extension of such period) under the HSR Act and all other Antitrust Approvals, in each case, as soon as practicable (but in any event prior to the Termination Date) and (ii) otherwise cooperate in connection with any filing and in connection with resolving any investigation or other inquiry of any Governmental Entity relating to the HSR Act and all other Antitrust Approvals, except that nothing in this Section 5.4 shall require, or be construed to require, the parties to proffer or negotiate to, or agree or consent to, sell, license, dispose of or hold separate or agree to sell, license, dispose of or hold separate, or take any other action (including any contractual, behavioral or conduct restriction, agreement, commitment or remedy) with respect to, before or after the Orca Effective Time, any assets or businesses, or interests in any assets or businesses, of Topco, Laguna, Orca or any of their respective Subsidiaries, if such action would, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect on the Topco Group.

Agreement, and will furnish the other with information concerning itself, its Subsidiaries, directors, officers and stockholders and such other matters as is reasonably necessary or advisable in connection with any Filing made by or on behalf of the parties or any of their respective Subsidiaries to any Person, Governmental Entity or Self-Regulatory Organization, in connection with the Combinations and the other transactions contemplated by this Agreement.

(e) Status Updates and Notice. Laguna and Orca each shall keep the other promptly apprised of the status of matters relating to completion of the transactions contemplated hereby, including promptly furnishing the other with (i) written notice of the occurrence, or non-occurrence, of any event as to which they have knowledge that would reasonably be expected to cause any condition to the obligations of any party to effect the transactions contemplated hereby not to be satisfied; (ii) written notice of the failure of a party to satisfy, or the material breach by a party of, any covenant, condition or agreement to be complied with or satisfied by it pursuant to this Agreement which would reasonably be expected to result in any condition to the obligations of any party to effect the transactions contemplated hereby not to be satisfied (provided, however, that the delivery of any notice pursuant to this Section 5.4(e) shall not cure any breach of any representation, warranty, covenant or agreement contained in this Agreement or otherwise limit or affect the remedies available hereunder to the party receiving such notice); and (iii) copies of all substantive notices or other communications received by Laguna or Orca, as the case may be, or any of their respective Subsidiaries, from any Person, Governmental Entity or Self-Regulatory Organization, with respect to such transactions.

(f) Treatment of Sensitive/Privileged Information. Notwithstanding anything to the contrary contained herein, for any information exchanged under this Section 5.4, it is understood that Laguna and Orca may, as each deems necessary, reasonably designate any competitively sensitive material provided to the other party under this Section 5.4 or any subsection thereof as “outside counsel only.” Such materials and the information contained therein shall be given only to the outside legal counsel of the recipient and will not be disclosed by such outside counsel to employees, officers, or directors of the recipient unless express permission is obtained in advance from the source of the materials (Laguna or Orca, as the case may be) or its legal counsel; provided, further, that materials provided to the other party pursuant to this Section 5.4 or any subsection thereof may be redacted to remove references concerning the valuation of the transactions contemplated hereby.

Section 5.5. Access. From the date of this Agreement to the earlier of consummation of the Laguna Merger and the termination of this Agreement, the parties shall, and shall cause each of their respective Subsidiaries, and shall direct and use reasonable best efforts to cause their respective directors, officers, employees, counsel, accountants, consultants (including any investment banker or financial advisor and, in the case of Orca, Carlyle Investment Management L.L.C.) and, to the extent practical, other authorized agents, intermediaries, or third party representatives that act or perform services for or on behalf of such party (“Representatives”) to: (a) provide to each other and their respective Representatives, upon prior written notice, reasonable access, during normal business hours in such a manner as not to unreasonably interfere with the operation of any business conducted by Laguna or Orca, as applicable, to its officers, employees, properties, offices, other facilities and books and records; and (b) furnish promptly such information concerning its business, properties, contracts, assets and liabilities as the parties or their respective Representatives may reasonably request; provided, however, that each party shall not be required to (or to cause any of their respective Subsidiaries or Representatives to) afford such access or furnish such information (i) to the extent that it reasonably believes in good faith that doing so would: (A) result in the loss of attorney-client privilege; (B) violate any of its obligations with respect to confidentiality to any third party or otherwise breach, contravene or violate any then effective Contract to which it is party; or (C) breach, contravene, violate or result in liability under any applicable Law (it being agreed that the parties shall use their respective reasonable best efforts to reduce the scope of or eliminate the applicable restriction); or (ii) if Orca or Topco or any of their affiliates, on the one hand, and Laguna or any of its affiliates, on the other hand, are adverse parties in any legal proceeding or action, to the extent that is reasonably pertinent to such proceeding or action. The parties shall, and shall cause each of their respective Subsidiaries and shall direct and use reasonable best efforts to cause their respective Representatives to, hold all information provided or furnished pursuant to this Section 5.5 confidential in accordance with the terms of the Confidentiality Agreement.

(a) if the Orca Effective Time shall not have occurred by September 22, 2022 (such date as it may be extended under the proviso below, the “Termination Date”), whether such date is before or after the date of the receipt of the Laguna Requisite Vote or the Orca Requisite Vote; provided, however, that such date shall automatically be extended to January 22, 2023, if the only conditions that have not been satisfied (other than those conditions that Laguna and Orca have mutually agreed to waive, if and to the extent that such waiver is permitted by applicable Law, and other than those conditions that by their nature can only be satisfied at or immediately prior to the Scheme Effective Date) are one or more of the conditions set forth in (i) Section 6.1(c) to the extent relating to an Approval required by Section 6.1(e) or (ii) Section 6.1(e); provided, further, that the right to terminate this Agreement pursuant to this Section 7.2(a) may not be exercised by any party whose failure to perform any material covenant or obligation under this Agreement has been the primary cause of, or primarily resulted in, the failure of any such closing condition to be satisfied on or before the Termination Date;

(b) if (i) the Laguna Requisite Vote shall not have been obtained after a vote of the Laguna stockholders has been taken and completed at the Laguna Stockholders’ Meeting or at any adjournment or postponement thereof or (ii) the Orca Requisite Vote shall not have been obtained at the Orca Shareholder Meetings (or at any adjournment or postponement thereof) or the Orca Scheme is not sanctioned and the Orca Scheme Order is not issued by the English Court; or

(c) if any Governmental Entity that must grant a regulatory approval required under Section 6.1(e) has denied such grant in writing and such denial has become final, binding and non-appealable, or any Order permanently restraining, enjoining or otherwise prohibiting consummation of the Combinations shall become final and non-appealable.

Section 7.3. Termination by Laguna. This Agreement may be terminated by Laguna by action authorized by the Laguna Board:

(a) at any time prior to the receipt of the Orca Requisite Vote, if the Orca Board shall have effected a Change in Orca Recommendation (whether or not in compliance with Section 5.2);

(b) at any time prior to the Orca Effective Time, if Orca breaches or fails to perform any of its covenants or agreements contained in this Agreement, or if any of the representations or warranties of Orca contained herein fails to be true and correct, which breach or failure (i) would give rise to the failure of a condition set forth in Section 6.3(a) through (c) and (ii) is not reasonably capable of being cured by Orca by the Termination Date or is not cured by Orca within 45 days after receiving written notice from Laguna; provided, that the right to terminate this Agreement pursuant to this Section 7.3(b) may not be exercised by Laguna if Laguna’s failure to perform any material covenant or obligation under this Agreement has been the primary cause of, or primarily resulted in, the failure of any such closing condition to be satisfied on or before the Termination Date; or

(b) at any time prior to the Orca Effective Time, if Laguna breaches or fails to perform any of its covenants or agreements contained in this Agreement, or if any of the representations or warranties of Laguna contained herein fails to be true and correct, which breach or failure (i) would give rise to the failure of a condition set forth in Section 6.2(a) through (c) and (ii) is not reasonably capable of being cured by Laguna by the Termination Date or is not cured by Laguna within 45

A-53

days after receiving written notice from Orca; provided, that the right to terminate this Agreement pursuant to this Section 7.4(b) may not be exercised by Orca if Laguna’s failure to perform any material covenant or obligation under this Agreement has been the primary cause of, or primarily resulted in, the failure of any such closing condition to be satisfied on or before the Termination Date; or

(c) at any time prior to the receipt of the Orca Requisite Vote, if the Orca Board shall have effected a Change in Orca Recommendation in compliance with Section 5.2 in response to an Orca All Cash Superior Proposal and in order for Orca to enter into a merger agreement, acquisition agreement, purchase agreement or other similar agreement that the Orca Board has authorized and directed Orca to execute with respect to such Orca All Cash Superior Proposal; provided, however, that this Agreement may not be so terminated unless (i) prior to or simultaneously with such termination the payment required by Section 7.5(c) has been made in full to Orca in accordance with Section 7.5(c), and (ii) simultaneously or promptly following such termination Laguna enters into such agreement.

Section 7.5. Effect of Termination and Abandonment.

(a) Effect of Termination and Abandonment. In the event of termination of this Agreement pursuant to this Article VII (other than Section 7.1), written notice thereof shall be given to the other parties to this Agreement specifying the provisions of this ARTICLE VII to which such termination is made and the basis therefore described in reasonable detail, and this Agreement (other than as set forth in this Section 7.5 and 8.1) shall become void and of no effect with no liability on the part of any party (or of any of its directors, officers, employees, agents, legal and financial advisors or other Representatives); provided, however, that, except as otherwise provided herein, no such termination shall relieve any party of any liability or damages resulting from any fraud or willful and material breach of this Agreement; provided, further, that the parties shall cooperate with each other in connection with the withdrawal of any applications to or termination of proceedings before any Governmental Entity or any Self-Regulatory Organization in connection with the transactions contemplated by this Agreement. For purposes of this ARTICLE VII, (i) “fraud” shall mean, with respect to any Person, intentional (and not constructive) misrepresentation of a material fact by such Person with the actual knowledge (as opposed to imputed or constructive knowledge or knowledge that could have been obtained after inquiry, or recklessness or negligence) of such Person that such representation was false when made and which was made with the specific intent to induce the Person to whom such representation was made to enter into or consummate the transactions contemplated by this Agreement and (ii) “willful and material breach” shall mean a material breach that is a consequence of an act undertaken by the breaching party or failure to act by the breaching party with the knowledge that the taking of such act or such failure to act would, or would reasonably be expected to, cause a material breach of this Agreement.

(b) Termination Fee Payable by Laguna.

(i) In the event that (A) this Agreement is terminated by Orca pursuant to Section 7.4(a) or is terminated by either Laguna or Orca pursuant to Section 7.2(a) or 7.2(b)(i) (and, at the time of such termination pursuant to Section 7.2(a) or 7.2(b)(i), Orca had a right to terminate this Agreement pursuant to Section 7.4(a)), (B)(x) an Acquisition Proposal for Laguna shall have been publicly announced or made publicly known or otherwise communicated or made known to Laguna management or the Laguna Board (or any third party shall have publicly announced, communicated or made known a bona fide intention, whether or not conditional, to make a proposal with respect to an Acquisition Proposal) and not withdrawn prior to termination or such vote to adopt this Agreement, as applicable, at any time after the date of this Agreement and (y) this Agreement is subsequently terminated by Orca pursuant to Section 7.4(b) or is terminated by either Laguna or Orca pursuant to Section 7.2(a) or 7.2(b)(i) (and, at the time of such termination pursuant to Section 7.2(a) or 7.2(b)(i), Orca had a right to terminate this Agreement pursuant to Section 7.4(b) as a result of a failure by Laguna to perform any of its covenants or agreements contained in this Agreement), or (C) this Agreement is terminated by Laguna pursuant to Section 7.3(c), then, in any such case, Laguna shall, prior to or contemporaneously with such termination, pay or cause to be paid to Orca an amount equal to $207,839,918.46 (the “Laguna Termination Payment”) by wire transfer of same day funds, as reduced by the amount of any applicable Expense Reimbursement for Orca, if any.

(ii) In the event that (A) an Acquisition Proposal for Laguna shall have been publicly announced or made publicly known or otherwise communicated or made known to management or the Laguna Board (or any third party shall have publicly announced, communicated or made known a bona fide intention, whether or not conditional, to make a proposal with respect to an Acquisition Proposal) and not withdrawn prior to termination or such vote to adopt this Agreement, as applicable, at any time after the date of this Agreement, (B) this Agreement is subsequently terminated by Laguna or Orca pursuant to Section 7.2(a) or 7.2(b)(i), and (C) within nine (9) months of such termination pursuant to

A-54

Section 7.2(a) or 7.2(b)(i), Laguna or any of its Subsidiaries executes an Alternative Acquisition Agreement with respect to, or consummates, or approves or recommends to the Laguna stockholders to accept, any Acquisition Proposal (it being understood that, for purposes of this clause (C), the term “Acquisition Proposal” shall have the meaning assigned to such term in Section 5.2(a) except that each reference to “15% or more” in the definition of “Acquisition Proposal” and “Major Subsidiary” shall be deemed to be a reference to “50% or more”), then Laguna shall, prior to or contemporaneously with the completion of such acquisition or transaction, pay or cause to be paid to Orca, by wire transfer of same day funds, the Laguna Termination Payment, as reduced by the amount of any Expense Reimbursement for Orca previously paid, if any.

(iii) In the event that this Agreement is terminated by Orca pursuant to Section 7.2(b)(i) under circumstances in which the Laguna Termination Payment is not otherwise payable, then Laguna shall pay to Orca its reasonable documented out of pocket costs, fees, and expenses incurred in connection with its investigation, consideration, documentation, diligence and negotiations of this Agreement and the transactions contemplated hereby, including all fees and expenses of Orca’s and its Subsidiaries’ respective Representatives and financing sources (the “Expense Reimbursement for Orca”).

(c) Termination Fee Payable by Orca.

(i) In the event that (A) this Agreement is terminated by Laguna pursuant to Section 7.3(a) or is terminated by either Laguna or Orca pursuant to Section 7.2(a) or 7.2(b)(ii) (and, at the time of such termination pursuant to Section 7.2(a) or 7.2(b)(ii), Laguna had a right to terminate this Agreement pursuant to Section 7.3(a)), (B)(x) an Acquisition Proposal for Orca shall have been publicly announced or made publicly known or otherwise communicated or made known to Orca management or the Orca Board (or any third party shall have publicly announced, communicated or made known a bona fide intention, whether or not conditional, to make a proposal with respect to an Acquisition Proposal) and not withdrawn prior to termination or such vote to adopt this Agreement, as applicable, at any time after the date of this Agreement and (y) this Agreement is subsequently terminated by Laguna pursuant to Section 7.3(b) or is terminated by either Laguna or Orca pursuant to Section 7.2(a) or 7.2(b)(ii) (and, at the time of such termination pursuant to Section 7.2(a) or 7.2(b)(ii), Laguna had a right to terminate this Agreement pursuant to Section 7.3(b) as a result of a failure by Orca to perform any of its covenants or agreements contained in this Agreement), or (C) this Agreement is terminated by Orca pursuant to Section 7.4(c), then, in any such case, Orca shall, prior to or contemporaneously with such termination, pay or cause to be paid to Laguna an amount equal to $46,880,426.11 (the “Orca Termination Payment”) by wire transfer of same day funds, as reduced by the amount of any applicable Expense Reimbursement for Laguna, if any.

(ii) In the event that (A) an Acquisition Proposal for Orca shall have been publicly announced or made publicly known or otherwise communicated or made known to management or the Orca Board (or any third party shall have publicly announced, communicated or made known a bona fide intention, whether or not conditional, to make a proposal with respect to an Acquisition Proposal) and not withdrawn prior to termination or such vote to adopt this Agreement, as applicable, at any time after the date of this Agreement, (B) this Agreement is subsequently terminated by Laguna or Orca pursuant to Section 7.2(a) or 7.2(b)(ii), and (C) within nine (9) months of such termination pursuant to Section 7.2(a) or 7.2(b)(ii), Orca or any of its Subsidiaries executes an Alternative Acquisition Agreement with respect to, or consummates, or approves or recommends to Orca Shareholders to accept, any Acquisition Proposal (it being understood that, for purposes of this clause (C), the term “Acquisition Proposal” shall have the meaning assigned to such term in Section 5.2(a) except that each reference to “15% or more” in the definition of “Acquisition Proposal” and “Major Subsidiary” shall be deemed to be a reference to “50% or more”), then Orca shall, prior to or contemporaneously with the completion of such acquisition or transaction, pay or cause to be paid to Laguna, by wire transfer of same day funds, the Orca Termination Payment, as reduced by the amount of any Expense Reimbursement for Laguna previously paid, if any.

(iii) In the event that this Agreement is terminated by Laguna pursuant to Section 7.2(b)(ii) under circumstances in which the Orca Termination Payment is not otherwise payable, then Orca shall pay to Laguna its reasonable documented out of pocket costs, fees, and expenses incurred in connection with its investigation, consideration, documentation, diligence and negotiations of this Agreement and the transactions contemplated hereby, including all fees and expenses of Laguna and its Subsidiaries’ respective Representatives and financing sources (the “Expense Reimbursement for Laguna”).

(d) Nature of Termination Payment. The parties acknowledge and agree that neither the Laguna Termination Payment nor the Orca Termination Payment is a penalty but rather is a reasonable estimate of damages necessary to compensate Orca or Laguna, as the case may be, in the circumstances in which the Laguna Termination Payment or the Orca

A-55

Termination Payment, as applicable, is payable. The parties hereby acknowledge and agree that the amount of the Laguna Termination Payment or the Orca Termination Payment, if and as applicable, is fair, after taking into account the value of the Orca Scheme and Laguna Merger, the other transactions contemplated hereby and all the costs and expenses already incurred by the parties before entering into this Agreement. In no event shall Laguna, on the one hand, or Orca, on the other hand, be required to pay to the other party more than one Laguna Termination Payment or the Orca Termination Payment, if and as applicable, pursuant to this Section 7.5.

(e) Exclusive Remedy. Subject to Section 7.5(a) (including with respect to willful and material breach or fraud) and Section 7.5(f), in the event that the Laguna Termination Payment or the Orca Termination Payment, as applicable, is paid in accordance with this Section 7.5, Orca and Topco, or Laguna, as applicable shall have no further recourse against Laguna, on the one hand, or Orca and Topco, on the other, in each case, for any and all losses, claims, damages, liabilities, costs, fees, expenses (including reasonable attorney’s fees and disbursements), judgments, inquiries and fines suffered as a result of any breach of any representation, warranty, covenant or obligation in this Agreement, and neither Laguna and its affiliates nor Orca and its affiliates, as applicable, or any of their respective former, current or future Representatives, agents, partners, managers, members, stockholders, assignees or affiliates shall have any further liability or obligations relating to or arising out of this Agreement; provided, however, that the foregoing shall not impair the rights of the parties, if any, to obtain injunctive relief pursuant to Section 8.14.

(f) Interest and Collection Expenses. Each of Laguna and Orca acknowledges that the agreements contained in this Section 7.5 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other party would not enter into this Agreement; accordingly, if either party fails to promptly pay or cause to be paid the amount due pursuant to this Section 7.5, and, in order to obtain such payment, the other party commences a suit that results in a judgment against such party for the payment set forth in this Section 7.5 or any portion of such payment, such party shall pay the other party its costs and expenses (including attorneys’ fees) in connection with such suit, together with interest on the amount of the payment at the prime rate of Citibank, N.A., in effect on the date such payment was required to be paid, from the date on which such payment was required through the date of actual payment.

ARTICLE VIII

MISCELLANEOUS AND GENERAL

Section 8.1. Survival. This ARTICLE VIII and the agreements of Laguna and Orca contained in Section 5.10 (Indemnification; Directors’ and Officers’ Insurance) shall survive the consummation of the Combinations. This ARTICLE VIII, the agreements of Laguna and Orca contained in Section 5.9 (Expenses), Section 7.5 (Effect of Termination and Abandonment) and the Confidentiality Agreement shall survive the termination of this Agreement for the maximum period permitted by Law. No other representations, warranties, covenants and agreements in this Agreement shall survive the consummation of the Combinations or the termination of this Agreement; provided, that this Section 8.1 shall not limit any covenant or agreement of the parties which by its terms contemplates performance after the Laguna Effective Time, which shall survive to the extent expressly provided for herein.

Section 8.2. Modification or Amendment. Subject to the provisions of applicable Law, and except as otherwise provided in this Agreement, this Agreement may be amended, modified or supplemented only by action taken by or on behalf of their respective boards of directors and pursuant to a written instrument executed and delivered by all of the parties, whether before or after approval of the matters presented in connection with the Laguna Merger by the Laguna stockholders or the Orca Scheme by the Orca Shareholders; provided that, after any such approval, no amendment shall be made for which applicable Law or the rules of any relevant stock exchange requires further approval by such stockholders without such further approval.

Section 8.3. Extension; Waiver. At any time prior to the Orca Effective Time, the parties may (a) extend the time for the performance of any of the obligations or other acts of the other parties, (b) waive any inaccuracies in the representations and warranties contained in this Agreement or in any document delivered pursuant to this Agreement, (c) waive compliance with any covenants and agreements contained in this Agreement or (d) waive the satisfaction of any of the conditions contained in this Agreement. No extension or waiver by Laguna shall require the approval of the Laguna stockholders unless such approval is required by Law and no extension or waiver by Orca shall require the approval of the Orca Shareholders unless such approval is required by Law. Any agreement on the part of a party to any such extension or

A-56

waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

Section 8.4. Counterparts. This Agreement may be executed in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. The exchange of a fully executed Agreement (in counterparts or otherwise) by facsimile or by electronic delivery in .pdf format shall be sufficient to bind the parties to the terms and conditions of this Agreement.

Section 8.5. Governing Law; Jurisdiction, Waiver of Trial by Jury.

(a) Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to conflicts of laws principles that would result in the application of the Law of any other jurisdiction; provided, however, that the Orca Scheme and matters related thereto shall be governed by, and construed in accordance with, English Law.

(b) Dispute Resolution. Each party to this Agreement hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Court of Chancery of the State of Delaware, or, if (and only if) such court finds it lacks subject matter jurisdiction, the Federal court of the United States of America sitting in Delaware, and appellate courts thereof (the “Chosen Courts”), in any action or proceeding arising out of or relating to this Agreement or the agreements delivered in connection herewith or the transactions contemplated hereby or thereby or for recognition or enforcement of any judgment relating thereto, and each of the parties to this Agreement hereby irrevocably and unconditionally (i) agrees not to commence any such action or proceeding except in the Court of Chancery of the State of Delaware, or, if (and only if) such court finds it lacks subject matter jurisdiction, the Federal court of the United States of America sitting in Delaware, and appellate courts thereof, (ii) agrees that any claim in respect of any such action or proceeding shall be heard and determined in the Court of Chancery of the State of Delaware, or, if (and only if) such court finds it lacks subject matter jurisdiction, the Federal court of the United States of America sitting in Delaware, and appellate courts thereof, (iii) waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any such action or proceeding in such courts and (iv) waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such action or proceeding in such courts. Each of the parties to this Agreement agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Notwithstanding the foregoing, the Orca Scheme and matters related to the sanction thereof shall be subject to the jurisdiction of the English Court and any appellate courts therefrom. Each party irrevocably consents to service of process inside or outside the territorial jurisdiction of the courts referred to in this Section 8.5(b) in the manner provided for notices in Section 8.7. Nothing in this Agreement will affect the right of any party to serve process in any other manner permitted by Law.

(c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER OR RELATE TO THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) IT MAKES THIS WAIVER VOLUNTARILY, AND (D) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 8.5.

For the avoidance of doubt, this Section 8.5 shall survive the consummation of the Combinations.

Section 8.6. Disclosure Letters. Any disclosure contained in the Laguna Disclosure Letter or the Orca Disclosure Letter with reference to any section or subsection of this Agreement shall be deemed to apply to any other section or subsection of the Laguna Disclosure Letter or Orca Disclosure Letter, respectively, where the relevance of such disclosure is reasonably apparent on the face of such disclosure. The mere inclusion of any item in the Laguna Disclosure Letter as an

A-57

exception to a representation or warranty of Laguna in this Agreement or the Orca Disclosure Letter as an exception to a representation or warranty of Orca in this Agreement shall not be deemed to be an admission that such item is a material exception, fact, event or circumstance, or that such item, individually or in the aggregate, has had or is reasonably expected to have, a Material Adverse Effect on Laguna, Orca or Topco, as applicable, or trigger any other materiality qualification.

Section 8.7. Notices. Any notice, request, instruction or other document to be given hereunder by any party to the others shall be in writing, shall be deemed duly given on the date of delivery, unless such day is not a Business Day in the location of receipt, in which case it shall be deemed delivered on the next Business Day in the location of receipt, and delivered personally or sent by registered or certified mail, postage prepaid or by prepaid overnight courier (providing written proof of delivery), in each case with a copy delivered by electronic mail, or by confirmed electronic mail, addressed as follows:

or to such other persons or addresses as may be designated in writing by the party to receive such notice as provided above and notification of the same has been duly given to all other parties.

Section 8.8. Entire Agreement. This Agreement (including any exhibits hereto), the Orca Scheme Terms, the Laguna Disclosure Letter, the Orca Disclosure Letter and the Confidentiality Agreement, dated June 1, 2021, between Laguna and Orca (the “Confidentiality Agreement”) constitute the entire agreement, and supersede all other prior agreements, understandings, representations and warranties both written and oral, among the parties, with respect to the subject matter hereof.

Section 8.9. No Third-Party Beneficiaries. Except as provided in Section 5.10 (Indemnification; Directors’ and Officers’ Insurance) and Section 7.5(e) (Effect of Termination and Abandonment; Exclusive Remedy), each of which shall inure to the benefit of the Persons benefiting therefrom, this Agreement is not intended to, and does not, confer upon any Person other than the parties any rights or remedies hereunder. The parties agree that the rights of third-party beneficiaries under Section 5.10 shall not arise unless and until the Orca Effective Time occurs. The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of the parties hereto. Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance with Section 8.3 without notice or liability to any other person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Consequently, Persons other than the parties hereto may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date. For the avoidance of doubt, this Section 8.9 shall survive the Scheme Effective Date.

Section 8.10. Obligations of Laguna and Orca. Whenever this Agreement requires a Subsidiary of Topco, Laguna or Orca to take any action, such requirement shall be deemed to include an undertaking on the part of Topco, Laguna or Orca, as appropriate, to cause such Subsidiary to take such action.

Section 8.11. Severability. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability or the other provisions hereof. If any provision of this Agreement, or the application thereof to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction.

Section 8.12. Interpretation; Construction.

(a) The table of contents and headings herein are for convenience of reference only, do not constitute part of this Agreement and shall not be deemed to limit or otherwise affect any of the provisions hereof. Where a reference in this Agreement is made to a Section, Schedule or Exhibit, such reference shall be to a Section of, Schedule to or Exhibit to this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The term “knowledge of Laguna ” shall be deemed to mean the actual knowledge of the individuals set forth on Section 8.12 of the Laguna Disclosure Letter. The term “knowledge of Orca” or “knowledge of Topco” shall be deemed to mean the actual knowledge of the individuals set forth on Section 8.12 of the Orca Disclosure Letter. For purposes of this Agreement, whenever the context requires the singular number shall include the plural, and vice versa. All references in this Agreement to “$” are intended to refer to United States dollars. Any reference to a particular Law means such Law as amended, modified or supplemented (including all rules and regulations promulgated thereunder) and, unless otherwise provided, as in effect from time to time.

(b) The parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

Section 8.13. Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by any of the parties without the prior written consent of the other parties.

A-59

Any attempted or purported assignment in violation of the preceding sentence shall be null and void and of no effect whatsoever. Subject to the preceding two sentences, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns.

Section 8.14. Specific Performance.

(a) The parties agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the specific terms hereof or were otherwise breached. It is accordingly agreed that prior to the termination of this Agreement in accordance with ARTICLE VII, the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement (without necessity of posting bond or other security (any requirements therefor being expressly waived)) in the Chosen Court, this being in addition to any other remedy to which they are entitled at Law or in equity.

(b) Each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief as provided in this Section 8.14 on the basis that (i) the party seeking such relief has an adequate remedy at Law or (ii) an award of specific performance is not an appropriate remedy for any reason at Law or equity. Any party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement shall not be required to provide any bond or other security in connection with any such order or injunction.

(c) In no event shall Laguna’s, Topco’s, or Orca’s right to seek specific performance pursuant to this Section 8.14 reduce, restrict or otherwise limit any right of such party to terminate this Agreement and to be paid the Laguna Termination Payment or Orca Termination Payment, as and if applicable; provided, that in no event shall Laguna, Topco or Orca be entitled to both specific performance pursuant to this Section 8.14 and payment of the Laguna Termination Payment or Orca Termination Payment, as applicable, with respect to the same conduct or action.

A-70

the Board of Directors fix a record date (a “Demand Record Date”) for the purpose of determining the stockholders entitled to demand that the Secretary call such special meeting, which request shall be in proper written form and delivered personally or sent by registered mail to, and received by, the Secretary at the principal executive offices of the Corporation.

(c) Form of Request. To be in proper written form, a stockholder’s request for the Board of Directors to fix a Demand Record Date must set forth (i) as to each matter such stockholder or any beneficial owner on whose behalf such business is proposed (each, a “Requesting Party”) proposes to bring before the special meeting, a brief description of the business desired to be brought before the special meeting and the reasons for conducting such business at the special meeting, (ii) the name and address of each Requesting Party, (iii)(A) the class or series and number of shares of capital stock of the Corporation that are owned, directly or indirectly, beneficially or of record by each Requesting Party and any Stockholder Associated Person (as defined below) and (B) any derivative positions held or beneficially held by each Requesting Party and any Stockholder Associated Person and whether and the extent to which any hedging or other transaction or series of transactions has been entered into by or on behalf of, or any other agreement, arrangement or understanding (including, without limitation, any short position or any borrowing or lending of shares) has been made, the effect or intent of which is to mitigate loss to or manage risk or benefit of share price changes for, or to increase or decrease the voting power of, any such Requesting Party or any Stockholder Associated Person with respect to shares of the Corporation (which information described in this clause (iii) shall be supplemented by such Requesting Party not later than ten (10) days after the record date for the meeting to disclose such ownership and other information as of such record date); (iv) a description of all arrangements or understandings between each Requesting Party or any Stockholder Associated Person and any other person or persons (including their names) in connection with the request for the special meeting or the business proposed to be conducted at the special meeting and any material interest of each Requesting Party and any Stockholder Associated Person in such business; (v) a representation that such Requesting Party intends to appear in person or by proxy at the special meeting to bring such business before the meeting; (vi) a Business Solicitation Representation (as defined below) from each Requesting Party; and (vii) any other information relating to each Requesting Party that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for stockholder proposals pursuant to Section 14 of the Securities Exchange Act of 1934, as amended (such act, and the rules and regulations promulgated thereunder, the “Exchange Act”) or the rules and regulations promulgated thereunder (the “Proxy Rules”).

(d) Definitions. For purposes of these Bylaws, (i) “Business Solicitation Representation” shall mean, with respect to any person, a representation as to whether or not such person or any Stockholder Associated Person intends or is part of a group that intends to deliver a proxy statement and form of proxy to the holders of at least the percentage of the Corporation’s outstanding voting shares required under applicable law to adopt the business proposed by such person or otherwise to solicit proxies from stockholders in support of such proposed business; and (ii) “Stockholder Associated Person” shall mean, with respect to any person, (A) any person directly or indirectly controlling, controlled by, under common control with or acting in concert with such person or (B) any member of such person’s immediate family sharing the same household.

(e) Fixing of Demand Record Date. Within ten (10) days after receipt by the Secretary of a request to fix a Demand Record Date in proper written form and otherwise in compliance with this Section 2.3 from any stockholder of record, the Board of Directors may adopt a resolution fixing a Demand Record Date for the purpose of determining the stockholders entitled to demand that the Secretary call a special meeting, which date shall not precede the date upon which the resolution fixing the Demand Record Date is adopted by the Board of Directors. If no resolution fixing a Demand Record Date has been adopted by the Board of Directors within the ten (10)-day period after the date on which such a request to fix a Demand Record Date was received by the Secretary, the Demand Record Date in respect thereof shall be deemed to be the twentieth (20th) day after the date on which such a request was received (or, if such twentieth (20th) day is not a business day, the next business day). Notwithstanding anything in this Section 2.3 to the contrary, no Demand Record Date shall be fixed if the Board of Directors determines that the demand or demands that would otherwise be submitted following such Demand Record Date could not comply with the requirements set forth in clauses (ii), (iv), (v) or (vi) of Section 2.3(g) of these Bylaws.

(f) Demand to Call Special Meeting. In no event shall a special meeting of the stockholders be called pursuant to Section 2.3(a) of these Bylaws unless stockholders of record as of the Demand Record Date who hold the Requisite Percentage timely provide one or more demands to call such special meeting in writing and in proper written form to the Secretary at the principal executive offices of the Corporation. Only stockholders of record on the Demand Record Date shall be entitled to demand that the Secretary call a special meeting of the stockholders pursuant to Section 2.3(a) of these Bylaws. To be timely, a stockholder’s demand to call a special meeting must be delivered personally or sent by registered mail to, and received by, the Secretary at the principal executive offices of the Corporation not later than the thirtieth (30th) day following the Demand Record Date. To be in proper form for purposes of this Section 2.3, a demand to call a special meeting shall be

A-71

in writing and set forth (i) the business proposed to be conducted at the special meeting, (ii) the text of the proposal or business (including the text of any resolutions proposed for consideration), if applicable, (iii) with respect to any stockholder or stockholders submitting a demand to call a special meeting, the information required to be provided by a Requesting Party pursuant to Section 2.3(c) of these Bylaws, and (iv) any other information required by Sections 2.5 or 2.6 below, respectively. A stockholder may revoke a demand to call a special meeting by written revocation delivered to the Secretary at any time prior to the special meeting at the principal executive offices of the Corporation. If any such revocation(s) are received by the Secretary after the Secretary’s receipt of written demands from the holders of the Requisite Percentage of stockholders, and as a result of such revocation(s), there no longer are unrevoked demands from the Requisite Percentage of stockholders to call a special meeting, the Board of Directors shall have the discretion to determine whether or not to proceed with the special meeting.

(g) Defective Demand. The Secretary shall not accept, and shall consider ineffective, a written demand from a stockholder to call a special meeting (i) that does not comply with this Section 2.3, (ii) that relates to an item of business to be transacted at such meeting that is not a proper subject for stockholder action under applicable law, (iii) that includes an item of business to be transacted at such meeting that did not appear on the written request that resulted in the determination of the Demand Record Date, (iv) that relates to an item of business (other than the election of directors) that is identical or substantially similar to an item of business (a “Similar Item”) for which a record date for notice of a stockholder meeting (other than the Demand Record Date) was previously fixed and such demand is delivered between the time beginning on the sixty-first (61st) day after such previous record date and ending on the one-year anniversary of such previous record date, (v) if a Similar Item will be submitted for stockholder approval at any stockholder meeting to be held on or before the ninetieth (90th) day after the Secretary receives such demand, or (vi) if a Similar Item has been presented at the most recent annual meeting or at any special meeting held within one year prior to receipt by the Secretary of such demand to call a special meeting.

(h) Calling of Special Meeting. Notwithstanding anything in these Bylaws to the contrary, the Secretary shall not be required to call a special meeting pursuant to this Section 2.3 except in accordance with this Section 2.3. If the Board of Directors shall determine that any request to fix a record date for notice and voting for the special meeting or demand to call and hold a special meeting was not properly made in accordance with this Section 2.3, or shall determine that the stockholder or stockholders requesting that the Board of Directors fix such record date or submitting a demand to call the special meeting have not otherwise complied with this Section 2.3, then the Board of Directors shall not be required to fix such record date or to call and hold the special meeting. Subject to Section 2.3(f) of these Bylaws, after receipt of demands in proper written form and in accordance with this Section 2.3 from a stockholder or stockholders of record holding the Requisite Percentage, the Board of Directors shall duly call, and determine the date, time and place of, a special meeting of stockholders for the purpose or purposes, and to conduct the business, specified in the demands received by the Corporation. Notwithstanding anything in these Bylaws to the contrary, the Board of Directors may submit its own proposal or proposals for consideration at such a special meeting. The record date for notice and voting for such a special meeting shall be fixed in accordance with Section 2.14 of these Bylaws. The Board of Directors shall provide written notice of such special meeting to the stockholders in accordance with Section 2.4 of these Bylaws.

(i) Exchange Act. Notwithstanding the provisions of this Section 2.3, a stockholder shall also comply with all applicable requirements of the Exchange Act with respect to any request to fix a record date for notice and voting for the special meeting or demand to call a special meeting.

SECTION 2.4 NOTICE OF STOCKHOLDERS’ MEETINGS

(a) Timing and Content. Whenever stockholders are required or permitted to take any action at a meeting, notice of the meeting shall be given which shall state the place, if any, date and time of the meeting, the record date for determining the stockholders entitled to vote at the meeting, if such date is different from the record date for determining stockholders entitled to notice of meeting, the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called. Notice of any meeting shall be given not less than ten (10) nor more than sixty (60) days before the date of the meeting, by or at the direction of the Board of Directors, the Chairman of the Board, the President or the Secretary, to each stockholder entitled to vote at such meeting as of the record date for determining stockholders entitled to notice of the meeting.

(b) Notice in Writing. Unless otherwise required by law, notice may be given in writing directed to a stockholder’s mailing address as it appears on the records of the Corporation and shall be given (i) if mailed, when deposited in the United States mail, postage prepaid, and (ii) if delivered by courier service, the earlier of when the notice is received or left at such stockholder’s address.

A-72

(c) Notice by Other Methods. So long as the Corporation is subject to the Proxy Rules, notice shall be given in the manner required by such rules. To the extent permitted by the Proxy Rules, notice may be given by electronic transmission directed to the stockholder’s electronic mail address and if so given, shall be given when directed to such stockholder’s electronic mail address unless the stockholder has notified the Corporation in writing or by electronic transmission of an objection to receiving notice by electronic mail or such notice is prohibited by Section 232(e) of the DGCL. If notice is given by electronic mail, such notice shall comply with the applicable provisions of Sections 232(a) and 232(d) of the DGCL. Notice may be given by other means of electronic transmission with the consent of a stockholder in the manner permitted by Section 232(b) of the DGCL, and such notice shall be deemed given as provided therein.

SECTION 2.5 NATURE OF BUSINESS AT ANNUAL MEETINGS OF STOCKHOLDERS

(a) General. No business may be transacted at an annual meeting of stockholders, other than business that is either (i) specified in the Corporation’s proxy materials with respect to such meeting given by or at the direction of the Board of Directors (or any duly authorized committee thereof), (ii) otherwise properly brought before the annual meeting by or at the direction of the Board of Directors (or any duly authorized committee thereof) or (iii) otherwise properly brought before the annual meeting by any stockholder (A) who is a stockholder of record on the date of the giving of the notice provided for in this Section 2.5 and on the record date for the determination of stockholders entitled to notice of and to vote at such annual meeting, (B) who is entitled to vote at such annual meeting and (C) who complies with the procedures set forth in this Section 2.5. In addition to the other requirements set forth in this Section 2.5, a stockholder may not transact any business at an annual meeting unless (1) such stockholder and any beneficial owner on whose behalf such business is proposed (each, a “Proposing Party”) acted in a manner consistent with the representation made in the Business Solicitation Representation delivered as set forth in Section 2.5(d) and (2) such business is a proper matter for stockholder action under the DGCL. For the avoidance of doubt, the foregoing clause (iii) shall be the exclusive means for a stockholder to propose business (other than business included in the Corporation’s proxy materials pursuant to Rule 14a-8 under the Exchange Act) at an annual meeting of stockholders. Stockholders who nominate persons for election to the Board of Directors at an annual meeting must also comply with the requirements set forth in Section 2.6 of these Bylaws.

(b) Timing of Notice. In addition to any other applicable requirements, for business to be properly brought before an annual meeting by a stockholder, such stockholder must have given timely notice thereof in proper written form to the Secretary. To be timely, a stockholder’s notice must be received by the Secretary at the principal executive offices of the Corporation not less than ninety (90) days nor more than one hundred twenty (120) days prior to the first anniversary of the preceding year’s annual meeting of stockholders; provided, however, that in the event that the annual meeting is convened more than thirty (30) days before or more than sixty (60) days after such anniversary date, or if no annual meeting was held in the preceding year, notice by the stockholder to be timely must be so received no more than one hundred twenty (120) days prior to such annual meeting nor less than the later of (i) ninety (90) days prior to such annual meeting and (ii) ten (10) days after the day on which public disclosure of the date of the meeting is first made by the Corporation. For purposes of these Bylaws, “public disclosure” shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

(c) No Effect of Adjournment and Postponement. In no event shall an adjournment of an annual meeting, or a postponement of an annual meeting for which notice has been given, or the public disclosure thereof, commence a new time period for the giving of a stockholder’s notice as described above.

(d) Form of Notice. To be in proper written form, a stockholder’s notice to the Secretary must set forth (i) as to each matter each Proposing Party proposes to bring before the annual meeting, a brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting; (ii) the name and address of each Proposing Party; (iii)(A) the class or series and number of shares of capital stock of the Corporation that are owned, directly or indirectly, beneficially or of record by each Proposing Party and any Stockholder Associated Person and (B) any derivative positions held or beneficially held by each Proposing Party and any Stockholder Associated Person and whether and the extent to which any hedging or other transaction or series of transactions has been entered into by or on behalf of, or any other agreement, arrangement or understanding (including, without limitation, any short position or any borrowing or lending of shares) has been made, the effect or intent of which is to mitigate loss to or manage risk or benefit of share price changes for, or to increase or decrease the voting power of, any such Proposing Party or any Stockholder Associated Person with respect to shares of the Corporation (which information described in this clause (iii) shall be supplemented by such Proposing Party not later than ten (10) days after the record date for the meeting to disclose such ownership and other information as of such record date); (iv) a description of all arrangements or understandings between each Proposing Party or any Stockholder Associated Person and any other person or persons (including their names) in

A-73

connection with the proposal of such business by such Proposing Party and any material interest of each Proposing Party or any Stockholder Associated Person in such business; (v) a representation that such Proposing Party intends to appear in person or by proxy at the annual meeting to bring such business before the meeting; (vi) a Business Solicitation Representation from each Proposing Party; and (vii) any other information relating to each Proposing Party that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for stockholder proposals pursuant to the Proxy Rules.

(e) Improper Business. No business shall be conducted at the annual meeting of stockholders of the Corporation except business brought before the annual meeting in accordance with the procedures set forth in these Bylaws, including this Section 2.5. If the Chairman of the Board, the Board of Directors or the chairperson of an annual meeting determines that business was not properly proposed in accordance with such procedures, such business shall not be transacted. Notwithstanding the foregoing provisions of this Section 2.5, unless otherwise required by law, if the stockholder (or a qualified representative of the stockholder) does not appear at the annual meeting of stockholders of the Corporation to propose business, such proposed business shall not be transacted, notwithstanding that proxies in respect of such business may have been received by the Corporation. For purposes of this Section 2.5, to be considered a qualified representative of the stockholder, a person must be a duly authorized officer, manager or partner of such stockholder or must be authorized by a writing executed by such stockholder to act for such stockholder as proxy at the meeting of stockholders, and such person must produce such writing, or a reliable reproduction thereof, at the meeting of stockholders.

(f) Exchange Act. Notwithstanding the provisions of this Section 2.5, a stockholder shall also comply with all applicable requirements of the Exchange Act with respect to the proposal of business to be transacted at the annual meeting of stockholders. Nothing in this Section 2.5 shall be deemed to affect any right of (i) the Corporation to omit a proposal from the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act or (ii) stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act.

SECTION 2.6 NOMINATION OF DIRECTORS

(a) General. Only persons who are nominated in accordance with the procedures set forth in this Section 2.6 shall be eligible for election as directors of the Corporation, except as may be otherwise provided in the certificate of incorporation of the Corporation (as amended and restated from time to time, the “Certificate of Incorporation”), including, without limitation, the terms of any certificate of designation with respect to any series of preferred stock with respect to the right, if any, of holders of preferred stock of the Corporation to nominate and elect a specified number of directors in certain circumstances and except as may otherwise be provided in the Proxy Rules; provided, that, the advance notice requirements for nominations for the election of directors in these Bylaws shall not apply to the nominations of directors by Carlyle Partners VI Cayman Holdings (the “Specified Stockholder”) pursuant to and in accordance with the terms and conditions of the Principal Stockholders Agreement, dated as of December 22, 2021, by and among the Corporation, Quidel Corporation, Ortho Clinical Diagnostics Holdings plc and the Specified Stockholder. Nominations of persons for election to the Board of Directors may be made at any annual meeting of stockholders, or at any special meeting of stockholders called for the purpose of electing directors, (i) by or at the direction of the Board of Directors (or any duly authorized committee thereof) or (ii) by any stockholder (A) who is a stockholder of record on the date of the giving of the notice provided for in this Section 2.6 and on the record date for the determination of stockholders entitled to notice of and to vote at such meeting, (B) who is entitled to vote at such meeting and (C) who complies with the procedures set forth in this Section 2.6. In addition to the other requirements set forth in this Section 2.6, a stockholder may not present a nominee for election at an annual or special meeting unless such stockholder, and any beneficial owner on whose behalf such nomination is made, acted in a manner consistent with the representation made in the Nominee Solicitation Representation (as defined below) delivered as set forth in Section 2.6 (d).

(b) Nominee Information.

(i) To be eligible to be a nominee for election or re-election as a director of the Corporation, a person must deliver to the Secretary at the principal executive offices of the Corporation the following information:

(A) a written representation and agreement, which shall be signed by such person and pursuant to which such person shall represent and agree that such person (1) consents to serving as a director if elected and to being named in the Corporation’s proxy statement and form of proxy as a nominee, and currently intends to serve as a director for the full term for which such person is standing for election; (2) is not and will not become a party to any agreement, arrangement or understanding with, and has not given any commitment or assurance to, any person as to how the person, if elected as a director, will act or vote on any issue or question that has not been disclosed to the Corporation, or that could limit or

A-74

interfere with the person’s ability to comply, if elected as a director, with such person’s fiduciary duties under applicable law; (3) is not and will not become a party to any agreement, arrangement or understanding with any person other than the Corporation with respect to any direct or indirect compensation, reimbursement or indemnification in connection with service or action as a director or nominee that has not been disclosed to the Corporation; and (4) if elected as a director, will comply with all of the Corporation’s corporate governance, conflict of interest, confidentiality, and stock ownership and trading policies and guidelines, and any other Corporation policies and guidelines applicable to directors (which will be promptly provided following a request therefor); and

(B) all questionnaires prepared by the Corporation, completed and signed (including those questionnaires required of the Corporation’s directors and any other questionnaire the Corporation determines is necessary or advisable to assess whether a nominee will satisfy any qualifications or requirements imposed by the Certificate of Incorporation or these Bylaws, any law, rule, regulation or listing standard that may be applicable to the Corporation, and the Corporation’s corporate governance policies and guidelines) (all of the foregoing, “Questionnaires”). The Questionnaires shall be promptly provided following a request therefor.

(ii) such other information as the Corporation may reasonably request. The Corporation may request such additional information as necessary to permit the Corporation to determine the eligibility of such person to serve as a director of the Corporation, including information relevant to a determination whether such person can be considered an independent director. Such information shall be considered timely if provided to the Corporation within five (5) business days after a request therefor.

(iii) In the case of a nominee proposed pursuant to Section 2.3 or this Section 2.6, the Questionnaires described in Section (b)(i)(B) shall be considered timely if provided to the Corporation by the deadlines specified in these Bylaws.

All information provided pursuant to this Section 2.6 shall be deemed part of a stockholder’s demand under Section 2.3(f) or a stockholder’s notice submitted pursuant to this Section 2.6, as applicable.

(c) Timing of Notice. In addition to any other applicable requirements, for a nomination to be made by a stockholder, such stockholder must have given timely notice thereof in proper written form to the Secretary. To be timely, a stockholder’s notice must be received by the Secretary at the principal executive offices of the Corporation (i) in the case of an annual meeting of stockholders, not less than ninety (90) days nor more than one hundred twenty (120) days prior to the first anniversary of the preceding year’s annual meeting; provided, however, that in the event that the annual meeting is convened more than thirty (30) days before or more than sixty (60) days after such anniversary date, or if no annual meeting was held in the preceding year, notice by the stockholder to be timely must be so received no more than one hundred twenty (120) days prior to such annual meeting nor less than the later of (A) ninety (90) days prior to such annual meeting and (B) ten (10) days after the day on which public disclosure of the date of the meeting is first made by the Corporation; and (ii) in the case of a special meeting of stockholders called for the purpose of electing directors, no more than one hundred twenty (120) days before such special meeting nor less than the later of (A) ninety (90) days prior to such special meeting and (B) ten (10) days after the day on which public disclosure of the date of the special meeting is first made by the Corporation. In no event shall an adjournment of an annual or special meeting, or a postponement of such a meeting for which notice has been given, or the public disclosure thereof, commence a new time period for the giving of a stockholder’s notice as described above. Notwithstanding the foregoing, in the event that the number of directors to be elected to the Board of Directors at the annual meeting is increased effective after the time period for which nominations would otherwise be due under this Section 2.6 and there is no public announcement by the Corporation naming the nominees for the additional directorships at least one hundred (100) days prior to the first anniversary of the preceding year’s annual meeting, a stockholder’s notice required by this Section 2.6 shall also be considered timely, but only with respect to nominees for the additional directorships, if it shall be delivered to the Secretary at the principal executive offices of the Corporation not later than the close of business on the tenth (10th) day following the day on which such public announcement is first made by the Corporation.

(d) Form of Notice. To be in proper written form, a stockholder’s notice to the Secretary must set forth (i) as to each person whom the stockholder proposes to nominate for election as a director (A) the name, age, business address and residence address of such person; (B) the principal occupation or employment of such person; (C) the class or series and number of shares of capital stock (if any) of the Corporation that are owned, directly or indirectly, beneficially or of record by such person; (D) the information required to be submitted by nominees pursuant to Section 2.6(b)(i) above; provided, however, that the Questionnaires described in Section 2.6(b)(i)(B) above may be provided within the time period for delivery of a stockholder’s notice under this Section 2.6; and (E) any other information relating to such person that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for

A-75

election of directors in an election contest, or is otherwise required, pursuant to the Proxy Rules; and (ii) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf such nomination is made (each, a “Nominating Party”) (A) the name and address of each Nominating Party; (B)(1) the class or series and number of shares of capital stock of the Corporation that are owned, directly or indirectly, beneficially or of record by each Nominating Party and any Stockholder Associated Person and (2) any derivative positions held or beneficially held by each Nominating Party and any Stockholder Associated Person and whether and the extent to which any hedging or other transaction or series of transactions has been entered into by or on behalf of, or any other agreement, arrangement or understanding (including, without limitation, any short position or any borrowing or lending of shares) has been made, the effect or intent of which is to mitigate loss to or manage risk or benefit of share price changes for, or to increase or decrease the voting power of, any such Nominating Party or any Stockholder Associated Person with respect to shares of the Corporation (which information described in this clause (ii)(B) shall be supplemented by such Nominating Party not later than ten (10) days after the record date for the meeting to disclose such ownership and other information as of such record date); (C) a description of all arrangements or understandings between each Nominating Party or any Stockholder Associated Person and each proposed nominee or any other person or persons (including their names) pursuant to which the nomination(s) are to be made; (D) a representation that such Nominating Party intends to appear in person or by proxy at the meeting to nominate the persons named in its notice; (E) a representation (a “Nominee Solicitation Representation”) as to whether or not such Nominating Party or any Stockholder Associated Person intends or is part of a group that intends to deliver a proxy statement and form of proxy to a number of holders of the Corporation’s outstanding voting shares reasonably believed by such Nominating Party to be sufficient to elect its nominee or nominees or otherwise to solicit proxies from stockholders in support of such nominee or nominees; and (F) any other information relating to each Nominating Party that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of directors pursuant to the Proxy Rules.

(e) Defective Nominations. No person shall be eligible for election as a director of the Corporation unless nominated in accordance with the procedures set forth in these Bylaws, including this Section 2.6. If the Chairman of the Board, the Board of Directors or the chairperson of the meeting determines that a nomination was not made in accordance with such procedures, such defective nomination shall be disregarded. Notwithstanding the foregoing provisions of this Section 2.6, unless otherwise required by law, if the stockholder (or a qualified representative of the stockholder) does not appear at the annual or special meeting of stockholders of the Corporation to present such stockholder’s nomination, such nomination shall be disregarded, notwithstanding that proxies in respect of such vote may have been received by the Corporation. For purposes of this Section 2.6, to be considered a qualified representative of the stockholder, a person must be a duly authorized officer, manager or partner of such stockholder or must be authorized by a writing executed by such stockholder to act for such stockholder as proxy at the meeting of stockholders, and such person must produce such writing, or a reliable reproduction thereof, at the meeting of stockholders.

(f) Exchange Act. Notwithstanding the provisions of this Section 2.6, a stockholder shall also comply with all applicable requirements of the Exchange Act with respect to the nomination of directors. Nothing in this Section 2.6 shall be deemed to affect any rights of the holders of any series of preferred stock to elect directors as provided in the Certificate of Incorporation.

SECTION 2.7 QUORUM

The holders of a majority of the voting power of the Corporation’s capital stock issued and outstanding and entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders for the transaction of business except as otherwise provided by law or by the Certificate of Incorporation. Where a separate vote by a class or series is required, a majority of the voting power of the shares of such class or classes or series present in person or represented by proxy shall constitute a quorum entitled to take action with respect to such vote. If a quorum is not present or represented at any meeting of the stockholders, then either the chairman of the meeting or the stockholders entitled to vote thereat, present in person or represented by proxy, shall have the power to adjourn the meeting from time to time, in the manner provided in Section 2.8 of these Bylaws, until a quorum is present or represented. A quorum, once established, shall not be broken by the withdrawal of enough votes to leave less than a quorum.

SECTION 2.8 ADJOURNED MEETING; NOTICE

Any meeting of stockholders may be adjourned from time to time to reconvene at the same or some other place by holders of a majority of the voting power of the Corporation’s capital stock issued and outstanding and entitled to vote thereon, present in person or represented by proxy, though less than a quorum, or by any officer entitled to act as chairman or secretary of such meeting. When a meeting is adjourned to another time or place, if any, unless these Bylaws otherwise

A-76

require, notice need not be given of the adjourned meeting if the time and place, if any, thereof, and the means of remote communications, if any, by which stockholders may be deemed to be present in person or represented by proxy and vote at such adjourned meeting are announced at the meeting at which the adjournment is taken. At the adjourned meeting, the Corporation may transact any business that might have been transacted at the original meeting. If the adjournment is for more than thirty (30) days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at such meeting. If, after the adjournment, a new record date for determination of stockholders entitled to vote is fixed for the adjourned meeting, the Board of Directors shall give notice of the adjourned meeting to each stockholder of record as of the record date so fixed for notice of such adjourned meeting.

SECTION 2.9 CONDUCT OF BUSINESS

The Board of Directors may designate any officer or director of the Corporation to act as chairman of any meeting of stockholders. In the absence of any such designation, the President shall act as chairman of meetings of stockholders. The Board of Directors may adopt by resolution such rules and regulations for the conduct of any meeting of stockholders as it shall deem appropriate. Except to the extent inconsistent with such rules and regulations as adopted by the Board of Directors, the chairman of any meeting of stockholders shall have the right and authority to convene and (for any or no reason) to recess or adjourn the meeting, to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such chairman, are appropriate for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board of Directors or prescribed by the chairman of the meeting, may include, without limitation, the following: (a) the establishment of an agenda or order of business for the meeting; (b) the determination of when the polls shall open and close for any given matter to be voted on at the meeting; (c) rules and procedures for maintaining order at the meeting and the safety of those present; (d) limitations on attendance at or participation in the meeting to stockholders of record of the Corporation, their duly authorized and constituted proxies or such other persons as the chairman of the meeting shall determine; (e) restrictions on entry to the meeting after the time fixed for the commencement thereof; and (f) limitations on the time allotted to questions or comments by participants. Except to the extent determined by the Board of Directors or the chairman of the meeting, meetings of stockholders shall not be required to be held in accordance with the rules of parliamentary procedure. The Secretary shall act as secretary of the meeting but, in the Secretary’s absence, the chairman of the meeting may appoint any person to act as secretary of the meeting.

SECTION 2.10 VOTING

(a) Generally. Except as provided in the Certificate of Incorporation, every stockholder having the right to vote shall have one vote for each share of stock having voting power registered in such stockholder’s name on the books of the Corporation. Such votes may be cast in person or by proxy as provided in Section 2.16 of these Bylaws. The Board of Directors, in its discretion, or the chairman of the meeting, in the chairman’s discretion, may require that any votes cast at such meeting shall be cast by written ballot.

(b) Matters Other Than Election of Directors. Any matter brought before any meeting of stockholders, other than the election of directors, shall be decided by the affirmative vote of the holders of a majority of the voting power of the Corporation’s capital stock present in person or represented by proxy at the meeting and entitled to vote on such matter, voting as a single class, unless the matter is one upon which, by express provision of law, the Certificate of Incorporation or these Bylaws, a different vote is required, in which case such express provision shall govern and control the decision of such matter.

(c) Election of Directors. Except as otherwise required by law or the Certificate of Incorporation, directors shall be elected by a plurality of the voting power of the Corporation’s capital stock present in person or represented by proxy at the meeting and entitled to vote on the election of directors.

SECTION 2.11 VOTING OF STOCK OF CERTAIN HOLDERS

Shares of stock of the Corporation standing in the name of another corporation or entity, domestic or foreign, and entitled to vote may be voted by such officer, agent or proxy as the bylaws or other internal regulations of such corporation or entity may prescribe or, in the absence of such provision, as the board of directors or comparable body of such corporation or entity may determine. Shares of stock of the Corporation standing in the name of a deceased person, a minor, an incompetent or a debtor in a case under Title 11, United States Code, and entitled to vote may be voted by an administrator, executor, guardian, conservator, debtor-in-possession or trustee, as the case may be, either in person or by proxy, without transfer of such shares into the name of the official or other person so voting. A stockholder whose shares of stock of the Corporation are pledged shall be entitled to vote such shares, unless on the transfer records of the Corporation such

A-77

stockholder has expressly empowered the pledgee to vote such shares, in which case only the pledgee, or the pledgee’s proxy, may vote such shares.

SECTION 2.12 TREASURY STOCK

Shares of stock of the Corporation belonging to the Corporation, or to another corporation a majority of the shares entitled to vote in the election of directors of which are held by the Corporation, shall not be voted at any meeting of stockholders of the Corporation and shall not be counted in the total number of outstanding shares for the purpose of determining whether a quorum is present. Nothing in this Section 2.12 shall limit the right of the Corporation to vote shares of stock of the Corporation held by it in a fiduciary capacity.

SECTION 2.13 WAIVER OF NOTICE

Whenever notice is required to be given to a stockholder under any provision of the DGCL, the Certificate of Incorporation or these Bylaws, a written waiver thereof, signed by such stockholder entitled to notice, or a waiver by electronic transmission by such stockholder entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. Any stockholder may waive notice of any meeting before or after the meeting. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any annual or special meeting of the stockholders need be specified in any written waiver of notice, or any waiver by electronic transmission, unless so required by law.

SECTION 2.14 RECORD DATE FOR STOCKHOLDER NOTICE, VOTING AND GIVING CONSENTS

In order that the Corporation may determine the stockholders entitled to notice of any meeting of stockholders or any adjournment thereof, or entitled to express consent to corporate action in writing without a meeting, or entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix a record date, which record date shall not precede the date on which the resolution fixing the record date is adopted and which record date shall not be more than sixty (60) nor less than ten (10) days before the date of such meeting, nor more than sixty (60) days prior to any other action. If the Board of Directors so fixes a date for any meeting of stockholders or any adjournment thereof, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board of Directors determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the Board of Directors in accordance with these Bylaws:

(a) the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held; and

(b) the record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may at or after adjournment fix a new record date for the determination of stockholders entitled to vote at the adjourned meeting, and in such case, shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance with the foregoing provisions of this Section 2.14. Notwithstanding anything to the contrary contained in this Section 2.14, the procedures for fixing a Demand Record Date shall be as set forth in Section 2.3 of these Bylaws, and the record date for determining stockholders entitled to express consent to corporate action in writing without a meeting shall be determined in accordance with Section 2.15 of these Bylaws.

SECTION 2.15 ACTION BY WRITTEN CONSENT IN LIEU OF A MEETING

(a) General. Any action required or permitted to be taken at an annual or special meeting of stockholders may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, (i) shall be signed by stockholders of record on the record date fixed pursuant to Section 2.15(b) below (the “Written Consent Record Date”) of outstanding shares of the Corporation having not less than the minimum number of votes that

A-78

would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and (ii) shall be delivered personally or sent by registered mail to, and received by, the Secretary at the principal executive offices of the Corporation. Every written consent shall bear the date of the signature of each stockholder who signs the consent, and no written consent shall be effective to take corporate action unless, within sixty (60) days of the earliest dated valid consent delivered in the manner described in this Section 2.15, written consents signed by a sufficient number of holders to take such action are delivered to the Corporation in the manner described in this Section 2.15. Only stockholders of record on the Written Consent Record Date shall be entitled to consent to corporate action in writing without a meeting.

(b) Request to Fix Written Consent Record Date. Any stockholder of record seeking to have the stockholders of the Corporation authorize or take any action by written consent shall first request in writing that the Board of Directors fix a record date for the purpose of determining the stockholders entitled to authorize or take such action, which request shall be in proper form and delivered personally or sent by registered mail, and received by, the Secretary at the principal executive offices of the Corporation. Within ten (10) days after receipt by the Secretary of a request in proper form and otherwise in compliance with this Section 2.15(b) from any such stockholder, the Board of Directors may adopt a resolution fixing a record date for the purpose of determining the stockholders entitled to express consent to corporate action in writing without a meeting, which date shall not be more than ten (10) days after the date upon which the resolution fixing such record date is adopted by the Board of Directors. If no resolution fixing a record date has been adopted by the Board of Directors within such ten (10)-day period after the date on which such a request is received by the Secretary, the record date for determining stockholders entitled to express consent to such action, (i) when no prior action of the Board of Directors is required by applicable law, shall be as of the close of business on the first day on which a valid signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation in the manner described in this Section 2.15 and (ii) when prior action of the Board of Directors is required by applicable law, shall be as of the close of business on the day on which the Board of Directors adopts the resolution taking such prior action.

(c) Form of Request. To be in proper written form, a stockholder’s request for the Board of Directors to fix a Written Consent Record Date must set forth (i) as to each action such stockholder and any beneficial owner on whose behalf such action is proposed to be taken by written consent (each, a “Soliciting Party”), a brief description of the action desired to be taken by written consent (including the text of any proposal, the text of any resolutions to be effected by consent and the language of any proposed amendment to these Bylaws) and the reasons for taking such action; (ii) the name and address of each Soliciting Party; (iii)(A) the class or series and number of shares of capital stock of the Corporation that are owned, directly or indirectly, beneficially or of record by each Soliciting Party and any Stockholder Associated Person and (B) any derivative positions held or beneficially held by each Soliciting Party and any Stockholder Associated Person and whether and the extent to which any hedging or other transaction or series of transactions has been entered into by or on behalf of, or any other agreement, arrangement or understanding (including, without limitation, any short position or any borrowing or lending of shares) has been made, the effect or intent of which is to mitigate loss to or manage risk or benefit of share price changes for, or to increase or decrease the voting power of, any such Soliciting Party or any Stockholder Associated Person with respect to shares of the Corporation (which information described in this clause (iii) shall be supplemented by such Soliciting Party not later than ten (10) days after the Written Consent Record Date to disclose such ownership and other information as of the Written Consent Record Date); (iv) a description of all arrangements or understandings between each Soliciting Party or any Stockholder Associated Person and any other person or persons (including their names) in connection with the action proposed to be taken by written consent and any material interest of each Soliciting Party and any Stockholder Associated Person in such action; (v) any other information that would be required under Section 2.5(d) or Section 2.6(d) of these Bylaws if such Soliciting Party had proposed to take action at a stockholder meeting rather than by written consent; (vi) a representation as to whether or not such Soliciting Party or any Stockholder Associated Person intends or is part of a group that intends to solicit, or participate in the solicitation of, proxies or written consents from the holders of at least the percentage of the Corporation’s outstanding voting shares required under applicable law to take action by written consent or otherwise to solicit written consents from stockholders in support of such proposal; and (vii) any other information relating to each Soliciting Party that would be required to be disclosed in an information statement or other filings required to be made in connection with solicitations of consents pursuant to the Proxy Rules.

(d) Deficient Request; Notice to Stockholders. Notwithstanding anything in these Bylaws to the contrary, no action may be taken by the stockholders by written consent except in accordance with this Section 2.15. If the Board of Directors shall determine that any request to fix a Written Consent Record Date or to take stockholder action by written consent was not properly made in accordance with this Section 2.15, or the stockholder or stockholders seeking to take such action do not otherwise comply with this Section 2.15, then the Board of Directors shall not be required to fix a Written Consent Record Date and any such purported action by written consent shall be null and void to the fullest extent permitted by applicable law.

Prompt notice of the taking of corporate action without a meeting by less than unanimous written consent shall be given to those stockholders who have not consented in writing and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting if the record date for notice of such meeting had been the date on which written consents signed by a sufficient number of stockholders to take the action were delivered to the Secretary as provided in this Section 2.15.

(e) Exchange Act. Notwithstanding the provisions of this Section 2.15, a stockholder shall also comply with all applicable requirements of the Exchange Act with respect to stockholders seeking to take action by written consent.

Each stockholder entitled to vote at a meeting of stockholders or to express consent to corporate action in writing without a meeting, or such stockholder’s authorized officer, director, employee or agent, may execute a document authorizing another person or persons to act for such stockholder as proxy, but no such proxy shall be voted or acted upon after three (3) years from its date, unless the proxy provides for a longer period.

The Corporation shall prepare, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at such meeting; provided, however, that if the record date for determining the stockholders entitled to vote is less than ten (10) days before the meeting date, the list shall reflect the stockholders entitled to vote as of the tenth (10th) day before the meeting date, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Nothing in this Section 2.17 shall require the Corporation to include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any stockholder for any purpose germane to the meeting for a period of at least ten (10) days prior to the meeting, either (a) during ordinary business hours at the principal executive offices of the Corporation or (b) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting. In the event that the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to stockholders of the Corporation. If the meeting is to be held at a place, then the list shall be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to examination by any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to gain access to such list shall be provided with the notice of the meeting.

Unless otherwise required by applicable law, inspectors may be officers, employees or agents of the Corporation. Each inspector, before entering upon the discharge of the duties of inspector, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of such inspector’s ability.

If the notice is sent by United States mail or sent by overnight courier, such notice shall be deemed to be given at the time when it is deposited in the United States mail with first-class postage prepaid or deposited with the overnight courier. Notice by facsimile or electronic mail shall be deemed given when the notice is transmitted. The notice need not specify the place of the meeting (if the meeting is to be held at the principal executive offices of the Corporation) nor the purpose of the meeting.

SECTION 3.8 QUORUM; ADJOURNED MEETING

At all meetings of the Board of Directors, a majority of the directors constituting the Board of Directors shall constitute a quorum for the transaction of business and the act of a majority of the directors present at any meeting at which there is a quorum shall be the act of the Board of Directors. A meeting at which a quorum is initially present may continue to transact business notwithstanding the withdrawal of directors, if any action taken is approved by at least a majority of the required quorum for that meeting. If a quorum is not present at any meeting of the Board of Directors, then the directors present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting of the time and place of the adjourned meeting, until a quorum is present.

SECTION 3.10 WAIVER OF NOTICE

Any director may waive notice of any meeting before or after the meeting. Attendance of a director at a meeting shall constitute a waiver of notice of such meeting, except when the director attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the directors need be specified in any notice or any waiver of notice of such meeting, unless required by law.

SECTION 3.11 BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING

Such director or directors in attendance may further take action to appoint one or more of themselves or other directors to membership on any standing or temporary committees of the Board of Directors as they shall deem necessary and appropriate. Except as the Board of Directors may otherwise determine, during any Emergency, the Corporation and its directors and officers may exercise any authority and take any action or measure contemplated by Section 110 of the DGCL.

ARTICLE IV

COMMITTEES

The Board of Directors may from time to time designate one or more committees of the Board of Directors, with each committee to consist of one or more of the directors of the Corporation. The Board of Directors may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of such committee. In the absence or disqualification of a member of a committee, and in the absence of a designation by the Board of Directors of an alternate member to replace the absent or disqualified member, the member or members thereof present at any meeting and not disqualified from voting, whether or not such member or members constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in the place of any such absent or disqualified member.

A-83

redemption, dissolution, any distribution of assets of the Corporation or the conversion into, or the exchange of such shares for, shares of any other class or classes or any other series of the same or any other class or classes of stock of the Corporation or fix the number of shares of any series of stock or authorize the increase or decrease of the shares of any series), (b) adopt an agreement of merger or consolidation under Section 251 or 252 of the DGCL, (c) recommend to the stockholders the sale, lease or exchange of all or substantially all of the Corporation’s property and assets, (d) recommend to the stockholders a dissolution of the Corporation or a revocation of a dissolution, or (e) amend the Bylaws of the Corporation; and, unless the resolutions of the Board of Directors establishing the committee, as such resolutions may be amended from time to time, expressly so provide, no such committee shall have the power or authority to declare a dividend, to authorize the issuance of stock or to adopt a certificate of ownership and merger pursuant to Section 253 of the DGCL.

Unless the resolutions of the Board of Directors establishing the committee, as such resolutions may be amended from time to time, expressly otherwise provide, the Board of Directors shall have power at any time to fill vacancies in, to change the membership of or to dissolve any such committee. A majority of the directors then serving on a committee shall constitute a quorum for the transaction of business by the committee except as otherwise required by law, the Certificate of Incorporation or these Bylaws, and except as otherwise provided in a resolution of the Board of Directors; provided, however, that in no case shall a quorum be less than one-third of the directors then serving on the committee. Unless the Certificate of Incorporation, these Bylaws or a resolution of the Board of Directors requires a greater number, the vote of a majority of the members of a committee present at a meeting at which a quorum is present shall be the act of the committee. Meetings and actions of committees shall be governed by, and held and taken in accordance with the following provisions of Article III of these Bylaws: Section 3.5 (Place of Meetings; Meetings by Telephone), Section 3.6 (Regular Meetings), Section 3.7 (Special Meetings; Notice), Section 3.8 (With Respect to Adjournment), Section 3.9 (Conduct of Business), Section 3.10 (Waiver of Notice), and Section 3.11 (Board Action by Written Consent Without a Meeting), with such changes in the context of those Bylaws as are necessary to substitute the committee and its members for the Board of Directors and its members; provided, however, that the time of regular meetings of committees may also be called by resolution of the Board of Directors and that alternative members of a committee shall be entitled to receive notice of special meetings of such committee and shall have the right to attend all meetings of such committee. The Board of Directors may adopt rules for the government of any committee not inconsistent with the provisions of these Bylaws.

INDEMNITY

SECTION 6.1 THIRD-PARTY ACTIONS

Subject to Section 6.4 of these Bylaws, the Corporation shall, to the fullest extent permitted by the DGCL as the same exists or may hereafter be amended, indemnify and hold harmless any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, whether internal or external, (a “Proceeding”) (other than an action by or in the right of the Corporation) by reason of the fact that such person is or was a director or officer (as defined in Section 6.8, below) of the Corporation, or while a director or officer of the Corporation is or was serving at the request of the Corporation as a director, officer, employee, agent or trustee of another corporation, partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan, whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee, agent or trustee or in any other capacity while serving as a director, officer, employee, agent or trustee, from and against expenses (including attorneys’ fees), judgments, fines, ERISA excise taxes and amounts paid in settlement actually and reasonably incurred by such person in connection with such Proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. The termination of any Proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent shall not, of itself, create a presumption that the person did not act in good faith and in a manner which such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that such person’s conduct was unlawful.

SECTION 6.2 ACTIONS BY OR IN THE RIGHT OF THE CORPORATION

Subject to Section 6.4 of these Bylaws, the Corporation shall, to the fullest extent permitted by the DGCL, indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed Proceeding by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that such person is or was a director or officer of the Corporation, or while a director or officer of the Corporation is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with

A-86

the defense or settlement of such Proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall have determined upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

SECTION 6.3 SUCCESSFUL DEFENSE

To the extent required by Section 145(c)(1) of the DGCL, a current or former director or officer (as defined therein) of the Corporation who has been successful on the merits or otherwise in defense of any Proceeding referred to in Section 6.1 or Section 6.2 of these Bylaws, or in defense of any claim, issue or matter therein, shall be indemnified under this Section 6.3 against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith. Any other person who is or was an officer of the Corporation, as defined in Section 6.8, shall also be entitled to such indemnification. Indemnification under this Section 6.3 shall not be subject to satisfaction of a standard of conduct, and the Corporation may not assert the failure to satisfy a standard of conduct as a basis to deny indemnification or recover amounts advanced, including in a suit brought pursuant to Section 6.11 (notwithstanding anything to the contrary therein).

SECTION 6.4 DETERMINATION OF CONDUCT

Any indemnification (unless ordered by a court or required by Section 6.3) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director or officer is proper in the circumstances because such person has met the applicable standard of conduct set forth in Section 6.1 or Section 6.2 of these Bylaws. Such determination shall be made (a) by a majority vote of the Disinterested Directors (as defined below), whether or not such majority constitutes a quorum, (b) if there are no Disinterested Directors, or if the Disinterested Directors so direct, by independent legal counsel in a written opinion or (c) by the stockholders (but only if a majority of the Disinterested Directors, if they constitute a quorum of the Board of Directors, presents the matter to the stockholders for their determination). Notwithstanding the foregoing, a director or officer of the Corporation shall be able to contest any determination that such person has not met the applicable standard of conduct set forth in Section 6.1 or Section 6.2 of these Bylaws by petitioning a court of appropriate jurisdiction.

SECTION 6.5 PAYMENT OF EXPENSES IN ADVANCE

To the fullest extent permitted by the DGCL, expenses incurred in defending or settling a Proceeding by any person who may be entitled to indemnification pursuant to Section 6.1 or Section 6.2 of these Bylaws shall be paid by the Corporation in advance of the final disposition of such Proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the Corporation as authorized in this Article VI.

SECTION 6.6 INDEMNITY NOT EXCLUSIVE

The indemnification and advancement of expenses provided by, or granted pursuant to, this Article VI shall not be deemed exclusive of, nor deemed to be a limitation of, any other rights to which those seeking indemnification or advancement of expenses may be entitled under the Certificate of Incorporation or any agreement, vote of stockholders or disinterested directors or otherwise. The Corporation is specifically authorized to enter into individual contracts with any or all of its directors, officers, employees or agents respecting indemnification and advancement of expenses, to the fullest extent not prohibited by the DGCL or other applicable law.

SECTION 6.7 INSURANCE

To the fullest extent permitted by the DGCL, the Corporation shall have the power to purchase and maintain insurance on behalf of any person who is or was a director or officer of the Corporation against any liability asserted against such person, whether or not the Corporation would have the power to indemnify such person against such liability under the provisions of this Article VI.

A-87

Upon resolution passed by the Board of Directors, the Corporation may establish a trust or other designated account, grant a security interest or use other means (including, without limitation, a letter of credit), to ensure the payment of any or all of its obligations arising under this Article VI or agreements which may be entered into between the Corporation and its officers and directors from time to time.

SECTION 6.10 INDEMNIFICATION OF OTHER PERSONS

The provisions of this Article VI shall not be deemed to limit the right of the Corporation, to the extent and in the manner permitted by law, to indemnify and to advance expenses to, or to purchase and maintain insurance on behalf of, persons other than those persons described in the first sentence of Section 6.1 of these Bylaws.

SECTION 6.11 DETERMINATION; CLAIM

If a claim for indemnification or advancement of expenses under this Article VI is not paid in full within 90 days after receipt by the Corporation of the written request therefor, the claimant shall be entitled to bring suit against the Corporation seeking an adjudication by a court of competent jurisdiction of such claimant’s entitlement to such indemnification or advancement of expenses, as applicable. The Corporation shall indemnify such person against any and all expenses that are incurred by such person in connection with any action for indemnification or advancement of expenses from the Corporation under this Article VI, to the extent such person is successful in such action, and to the extent not prohibited by law. In any such suit, the Corporation shall, to the fullest extent not prohibited by law, have the burden of proving that the claimant is not entitled to the requested indemnification or advancement of expenses.

SECTION 6.12 EFFECT OF REPEAL OR MODIFICATION

Any amendment, repeal or modification of any provision contained in this Article VI shall, unless otherwise required by law, be prospective only (except to the extent such amendment or change in law permits the Corporation to further limit or eliminate the liability of directors or officers) and shall not adversely affect any right or protection of any current or former director or officer of the Corporation existing at the time of such amendment, repeal or modification with respect to any acts or omissions occurring prior to such amendment, repeal or modification.

SECTION 6.13 SAVINGS CLAUSE

If this Article VI or any portion thereof shall be invalidated on any ground by any court of competent jurisdiction, then, subject to Section 6.4 of these Bylaws, the Corporation shall nevertheless indemnify each person seeking indemnification hereunder against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement with respect to any Proceeding, including a grand jury proceeding and an action or suit brought by or in the right of the Corporation, to the full extent permitted by any applicable provision of this Article VI that shall not have been invalidated or by any other applicable law.

A-88

SECTION 6.14 CONTINUATION OF INDEMNIFICATION AND ADVANCEMENT OF EXPENSES

The indemnification and advancement of expenses provided by, or granted pursuant to, this Article VI shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such person.

ARTICLE VII

FORUM FOR CERTAIN ACTIONS

(a) Forum. Unless the Corporation, in writing, selects or consents to the selection of an alternative forum (i) the sole and exclusive forum for any complaint asserting any internal corporate claims (as defined below), to the fullest extent permitted by law, and subject to applicable jurisdictional requirements, shall be the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have, or declines to accept, jurisdiction, another state court or a federal court located within the State of Delaware), and (ii) the sole and exclusive forum for any complaint asserting a cause of action arising under the Securities Act of 1933, to the fullest extent permitted by law, shall be the federal district courts of the United States of America. For the avoidance of doubt, this Article VII shall not apply to suits brought to enforce a duty or liability created by the Exchange Act. For purposes of this Article VII, “internal corporate claims” means claims, including claims in the right of the Corporation that are based upon a violation of a duty by a current or former director, officer, employee or stockholder in such capacity, or as to which the DGCL confers jurisdiction upon the Court of Chancery. Any person purchasing or otherwise acquiring or holding any interest in shares of capital stock of the Corporation shall be deemed to have notice of and consented to the provisions of this Article VII.

(b) Enforceability. If any provision of this Article VII shall be held to be invalid, illegal or unenforceable as applied to any person or circumstance for any reason whatsoever, then, to the fullest extent permitted by law, the validity, legality and enforceability of such provision in any other circumstance and of the remaining provisions of this Article VII (including, without limitation, each portion of any sentence of this Article VII containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) and the application of such provision to other persons or circumstances shall not in any way be affected or impaired thereby.

B-3

2.2 Representations and Warranties and Covenants of the Company Parties.

(a) Each of the Company, Orca and Laguna (each a “Company Party”) hereby represents, warrants and covenants, severally and not jointly, to the Carlyle Stockholders as follows: (a) such Company Party has full corporate power and authority to enter into this Agreement and perform its obligations hereunder; (b) this Agreement constitutes the valid and binding obligation of such Company Party enforceable against it in accordance with its terms; and (c) the execution, delivery and performance by such Company Party of this Agreement: (i) does not and will not violate any laws, rules or regulations of the United States or any state or other jurisdiction applicable to such Company Party, or require such Company Party to obtain any approval, consent or waiver of, or to make any filing with, any Person that has not been obtained or made; and (ii) does not and will not result in a breach of, constitute a default under, accelerate any obligation under or give rise to a right of termination of any indenture or loan or credit agreement or any other material agreement, contract, instrument, mortgage, lien, lease, permit, authorization, order, writ, judgment, injunction, decree, determination or arbitration award to which such Company Party is a party or by which the property of such Company Party is bound or affected, or result in the creation or imposition of any mortgage, pledge, lien, security interest or other charge or encumbrance on any of the assets or properties of such Company Party.

SECTION III. REGISTRATION RIGHTS

3.1 Demand and Piggyback Rights.

(a) Right to Demand a Non-Shelf Registered Offering. Upon the demand of any Carlyle Stockholder at any time and from time to time after the Closing, the Company will facilitate in the manner described in this Agreement a non-shelf registered offering of the Shares requested by the demanding Carlyle Stockholders to be included in such offering. A demand by Carlyle Stockholders for a non-shelf registered offering that will result in the imposition of a lockup on the Company and the Carlyle Stockholders may not be made unless: (i) the Shares requested to be sold by the demanding Carlyle Stockholders in such offering have an aggregate market value (based on the most recent closing price of the shares of Common Stock at the time of the demand) of at least $250 million (or such lesser amount if all Shares held by the demanding Carlyle Stockholders are requested to be sold), (ii) the duration of the lockup is no more than 90 days, and (iii) such lockups occur no more than twice in any 12-month period.

(b) Right to Piggyback on a Non-Shelf Registered Offering. In connection with any registered offering of shares of Common Stock covered by a non-shelf registration statement (whether pursuant to the exercise of demand rights or at the initiative of the Company), the Carlyle Stockholders may exercise piggyback rights to have included in such offering Shares held by them. The Company will facilitate in the manner described in this Agreement any such non-shelf registered offering.

(c) Right to Demand and be Included in a Shelf Registration. Upon the demand of any Carlyle Stockholder, made at any time and from time to time when the Company is eligible to utilize Form S-3 or a successor form to sell Shares in a secondary offering on a delayed or continuous basis in accordance with Rule 415 under the Securities Act, the Company will facilitate in the manner described in this Agreement a shelf registration of Shares held by such Carlyle Stockholder. Unless otherwise requested by any Carlyle Stockholder, any shelf registration filed by the Company covering Shares (whether pursuant to a Carlyle Stockholder demand or at the initiative of the Company) will cover Shares held by each of the Carlyle Stockholders (regardless of whether they demanded the filing of such shelf or not) up to an equivalent percentage of their original respective holdings as may be agreed upon by the demanding Carlyle Stockholders. If at the time of such request the Company is a WKSI, such shelf registration would, at the request of such Carlyle Stockholder, cover an unspecified number of Shares to be sold by the Company and the Carlyle Stockholders.

(d) Demand and Piggyback Rights for Shelf Takedowns. Upon the demand of one or more Carlyle Stockholders made at any time and from time to time, the Company will facilitate in the manner described in this Agreement a “takedown” of Shares off of an effective shelf registration statement. In connection with any underwritten shelf takedown (whether

B-4

pursuant to the exercise of such demand rights or at the initiative of the Company), the Carlyle Stockholders may exercise piggyback rights to have included in such takedown Shares held by them that are registered on such shelf. Notwithstanding the foregoing, Carlyle Stockholders may not demand a shelf takedown for an offering that will result in the imposition of a lockup on the Company and the Carlyle Stockholders unless (i) the Shares requested to be sold by the demanding Carlyle Stockholders in such takedown have an aggregate market value (based on the most recent closing price of the Shares at the time of the demand) of at least $250 million (or such lesser amount if all Shares held by the demanding Carlyle Stockholders are requested to be sold), (ii) the duration of the lockup is no more than 90 days, and (iii) such lockups occur no more than three times in the first 12 months after the Closing (provided that the aggregate lock-up period in such 12-month period shall not exceed 180 days) and no more than twice in any 12-month period after the first anniversary of the Closing.

(e) Right to Reload a Shelf. Upon the written request of a Carlyle Stockholder, the Company will file and seek the effectiveness of a post-effective amendment to an existing resale shelf in order to register up to the number of Shares of the Carlyle Stockholders previously taken down off of such shelf and not yet “reloaded” onto such shelf.

(f) Limitations on Demand and Piggyback Rights.

(i) Any demand for the filing of a registration statement or for a registered offering or takedown will be subject to the constraints of any applicable lockup arrangements, and such demand must be deferred until such lockup arrangements no longer apply. If a demand has been made for a non-shelf registered offering or for an underwritten takedown, no further demands may be made so long as the related offering is still being pursued. Notwithstanding anything in this Agreement to the contrary, the Carlyle Stockholders will not have piggyback or other registration rights with respect to registered primary offerings by the Company (i) covered by a Form S-8 registration statement or a successor form applicable to employee benefit-related offers and sales, (ii) where the Shares are not being sold for cash or (iii) where the offering is a bona fide offering of securities other than Shares, even if such securities are convertible into or exchangeable or exercisable for Shares.

(ii) The Company may postpone the filing of a demanded registration statement or suspend the effectiveness of any shelf registration statement or support for a takedown offering for a reasonable “blackout period” not in excess of 90 days if the Board of Directors of the Company determines that such registration or offering could materially interfere with a bona fide business or financing transaction of the Company or is reasonably likely to require premature disclosure of information, the premature disclosure of which could materially and adversely affect the Company; provided that the Company shall not postpone the filing of a demanded registration statement or suspend the effectiveness of any shelf registration statement pursuant to this Section 3.1(f)(ii) more than once in any 360 day period. The blackout period will end upon the earlier to occur of (i) a date not later than 90 days from the date such deferral commenced and (ii) the date upon which such information is otherwise disclosed.

(g) Expiration of Registration Rights. The rights of the Carlyle Stockholders under Section 3.1(a) shall expire when the Carlyle Stockholders, collectively, Beneficially Own less than five percent (5%) of the outstanding Shares and the other rights of the Carlyle Stockholders under this Section 3.1 shall expire on a holder-by-holder basis when a given Carlyle Stockholder Beneficially Owns less than one percent (1%) of the outstanding Shares; provided, in each case, such Carlyle Stockholder is able to sell the Shares Beneficially Held as of the Effective Date under Rule 144 under the Securities Act, without volume or manner of sale restrictions, at such time.

3.2 Notices, Cutbacks and Other Matters.

(a) Notifications Regarding Registration Statements. In order for one or more Carlyle Stockholders to exercise their right to demand that a registration statement be filed, they must so notify the Company in writing indicating the number of Shares sought to be registered and the proposed plan of distribution. The Company will keep the Carlyle Stockholders contemporaneously apprised of all pertinent aspects of its pursuit of any registration, whether pursuant to a Carlyle Stockholder demand or otherwise, with respect to which a piggyback opportunity is available (and in any event, at least five days before a filing of a registration statement). Pending any required public disclosure and subject to applicable legal requirements, the parties will maintain the confidentiality of these discussions.

(b) Notifications Regarding Registration Piggyback Rights. Any Carlyle Stockholder wishing to exercise its piggyback rights with respect to a non-shelf registration statement must notify the Company and the other Carlyle Stockholders of the number of Shares it seeks to have included in such registration statement. Such notice must be given as soon as practicable, but in no event later than 5:00 pm, New York City time, on the second trading day prior to (i) if

B-5

applicable, the date on which the preliminary prospectus intended to be used in connection with pre-effective marketing efforts for the relevant offering is expected to be finalized, and (ii) in any case, the date on which the pricing of the relevant offering is expected to occur. No such notice is required in connection with a shelf registration statement, as Shares held by all Carlyle Stockholders will be included up to the applicable percentage (unless otherwise requested by any Carlyle Stockholder).

(c) Notifications Regarding Demanded Underwritten Takedowns.

(i) The Company will keep the Carlyle Stockholders contemporaneously apprised of all pertinent aspects of any underwritten shelf takedown in order that they may have a reasonable opportunity to exercise their related piggyback rights (and in any event, at least two trading days before the filing of a prospectus supplement). Without limiting the Company’s obligation as described in the preceding sentence, having a reasonable opportunity requires that the Carlyle Stockholders be notified by the Company of an anticipated underwritten takedown (whether pursuant to a demand made by other Carlyle Stockholders or made at the Company’s own initiative) no later than 5:00 pm, New York City time, on (i) if applicable, the second trading day prior to the date on which the preliminary prospectus or prospectus supplement intended to be used in connection with pre-pricing marketing efforts for such takedown is finalized, and (ii) in all cases, the second trading day prior to the date on which the pricing of the relevant takedown occurs.

(ii) Any Carlyle Stockholder wishing to exercise its piggyback rights with respect to an underwritten shelf takedown must notify the Company and the other Carlyle Stockholders of the number of Shares it seeks to have included in such takedown. Such notice must be given as soon as practicable, but in no event later than 5:00 pm, New York City time, on (i) if applicable, the trading day prior to the date on which the preliminary prospectus or prospectus supplement intended to be used in connection with marketing efforts for the relevant offering is expected to be finalized, and (ii) in all cases, the trading day prior to the date on which the pricing of the relevant takedown occurs.

(iii) Pending any required public disclosure and subject to applicable legal requirements, the parties will maintain appropriate confidentiality of their discussions regarding a prospective underwritten takedown.

(d) Plan of Distribution, Underwriters and Counsel. If (i) a majority of the Shares proposed to be sold in an underwritten offering through a non-shelf registration statement or through a shelf takedown are being sold by the Company for its own account and (ii) such offering was initiated by the Company and not by any Carlyle Stockholder, the Company will be entitled to determine the plan of distribution and select the managing underwriters for such offering. Otherwise, the Carlyle Stockholders holding a majority of the Shares requested to be included in such offering will be entitled to determine the plan of distribution and select the managing underwriters, and such majority will also be entitled to select counsel for the selling Carlyle Stockholders (which may be the same as counsel for the Company). In the case of a shelf registration statement, the plan of distribution will provide as much flexibility as is reasonably possible, including with respect to resales by transferee Carlyle Stockholders.

(e) Cutbacks. If the managing underwriters advise the Company and the selling Carlyle Stockholders that, in their opinion, the number of Shares requested to be included in an underwritten offering exceeds the amount that can be sold in such offering without adversely affecting the distribution of the Shares being offered, such offering will include only the number of Shares that the underwriters advise can be sold in such offering.

(i) In the case of a registered offering upon the demand of one or more Carlyle Stockholders, the selling Carlyle Stockholders (including those Carlyle Stockholders exercising piggyback rights pursuant to Section 3.1(b)) collectively will have first priority and will be subject to cutback pro rata based on the proportion of all outstanding Shares that are held by each such selling Carlyle Stockholder at that time (up to the number of Shares initially requested by them to be included in such offering). To the extent of any remaining capacity, all other stockholders having similar registration rights will have second priority. Except as contemplated by the immediately preceding two sentences, if the Carlyle Stockholders are subject to a cutback, other selling stockholders will be included in an underwritten offering only with the consent of Carlyle Stockholders holding a majority of the Shares being sold in such offering.

(ii) In the case of a registered offering upon the initiative of the Company, the Company will have first priority. To the extent of any remaining capacity, the selling Carlyle Stockholders as a group, on the one hand, and all other stockholders having similar registration rights as a group, on the other hand, will be subject to cutback pro rata based on the number of Shares initially requested by such group to be included in such offering. The selling Carlyle Stockholders will be subject to cutback pro rata, based on the proportion of all outstanding Shares (as of the Closing) that were held by the Initial Carlyle Stockholder at the Closing (up to the number of Shares initially requested by them

B-6

to be included in such offering). Except as contemplated by the immediately preceding sentence, if the Carlyle Stockholders are subject to a cutback, other stockholders will be included in an underwritten offering only with the consent of a Carlyle Majority Interest.

(f) Withdrawals. Even if Shares held by a Carlyle Stockholder have been part of a registered underwritten offering, such Carlyle Stockholder may, no later than the time at which the public offering price and underwriters’ discount are determined with the managing underwriter, decline to sell all or any portion of the Shares being offered for its account.

(g) Expenses. All expenses incurred in connection with any registration statement or registered offering covering Shares held by Carlyle Stockholders, including, without limitation, all registration and filing fees, printing expenses (including printing certificates for the Shares in a form eligible for deposit with the Depository Trust Company and printing preliminary, supplemental and final prospectuses), word processing, duplicating, telephone and facsimile expenses, messenger and delivery expenses, transfer taxes, expenses incurred in connection with promotional efforts or “roadshows”, fees and disbursements of counsel (including the fees and disbursements of outside counsel for Carlyle Stockholders (which may be the same as counsel for the Company) and fees and disbursements of counsel to the underwriters with respect to “blue sky” qualification of such Shares and their determination for eligibility for investment under the laws of the various jurisdictions and in connection with any filing with, and clearance of any offering by, FINRA (up to the cap on such fees included in any applicable underwriting agreement)) and of the independent certified public accountants of the Company (including with respect to the preparation of customary financial statements required to be included in any offering document, the provision of any customary comfort letters), and the expense of qualifying such Shares under state blue sky laws (reasonably requested by the Carlyle Stockholders), will be borne by the Company. However, underwriters’, brokers’ and dealers’ discounts and commissions applicable to Shares sold for the account of a Carlyle Stockholder will be borne by such Carlyle Stockholder and such underwriter expenses will be paid by the Carlyle Stockholders. In the event that the Carlyle Stockholders elect to abandon a non-shelf registered offering, then such offering-related expenses shall be reimbursed by the Carlyle Stockholders unless such abandonment is based upon adverse Company-specific information or the imposition of a “blackout” period under Section 3.1(c)(ii).

3.3 Facilitating Registrations and Offerings.

(a) General. If the Company becomes obligated under this Agreement to facilitate a registration and offering of Shares on behalf of Carlyle Stockholders, the Company will do so with the same degree of care and dispatch as would reasonably be expected in the case of a registration and offering by the Company of Shares for its own account. Without limiting this general obligation, the Company will fulfill its specific obligations as described in this Section 3.3.

(b) Registration Statements. In connection with each registration statement that is demanded by Carlyle Stockholders or as to which piggyback rights otherwise apply, for a period of 12 months from the date of the prospectus relating to such registration of the resale of the Company will:

(i) prepare and file (or confidentially submit) with the SEC a registration statement covering the applicable Shares, (ii) prepare and file (or confidentially submit) such amendments or supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period ending when all of the securities covered by such registration statement have been disposed of in accordance with the intended methods of distribution by the sellers thereof set forth in such registration statement (but not in any event before the expiration of any longer period required under the Securities Act or, if such registration statement relates to an underwritten public offering, such longer period as in the opinion of counsel for the underwriters a prospectus is required by law to be delivered in connection with the sale of Shares by an underwriter or dealer), (iii) seek the effectiveness thereof, and (iv) file with the SEC prospectuses and prospectus supplements as may be required, all in consultation with the Carlyle Stockholders and as reasonably necessary in order to permit the offer and sale of the such Shares in accordance with the applicable plan of distribution;

(ii) (1) within a reasonable time prior to the filing of any registration statement, any prospectus, any amendment to a registration statement, amendment or supplement to a prospectus or any free writing prospectus, provide copies of such documents to the selling Carlyle Stockholders and to the underwriter or underwriters of an underwritten offering, if applicable, and to their respective counsel; fairly consider such reasonable changes in any such documents prior to or after the filing thereof as the counsel to the Carlyle Stockholders or the underwriter or the underwriters may request; and make such of the representatives of the Company as shall be reasonably requested by the selling Carlyle Stockholders or any underwriter available for discussion of such documents;

B-7

(2) within a reasonable time prior to the filing of any document which is to be incorporated by reference into a registration statement or a prospectus, provide copies of such document to counsel for the Carlyle Stockholders and underwriters; fairly consider such reasonable changes in such document prior to the filing thereof as counsel for such Carlyle Stockholders or such underwriter shall request; and make such of the representatives of the Company as shall be reasonably requested by such counsel available for discussion of such document;

(iii) cause each registration statement and the related prospectus and any amendment or supplement thereto, as of the effective date of such registration statement, amendment or supplement and during the distribution of the registered Shares (x) to comply in all material respects with the requirements of the Securities Act and the rules and regulations of the SEC and (y) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

(iv) notify each Carlyle Stockholder promptly, and, if requested by such Carlyle Stockholder, confirm such advice in writing, (i) when a registration statement has become effective and when any post-effective amendments and supplements thereto become effective if such registration statement or post-effective amendment is not automatically effective upon filing pursuant to Rule 462 under the Securities Act, (ii) of the issuance by the SEC or any state of any stop order, injunction or other order or requirement suspending the effectiveness of a registration statement or the initiation of any proceedings for that purpose, (iii) if, between the effective date of a registration statement and the closing of any sale of securities covered thereby pursuant to any agreement to which the Company is a party, the representations and warranties of the Company contained in such agreement cease to be true and correct in all material respects or if the Company receives any notification with respect to the suspension of the qualification of the Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose, and (iv) of the happening of any event during the period a registration statement is effective as a result of which such registration statement or the related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading and, if required by applicable law, prepare and file a supplement or amendment to such registration statement or prospectus so that, as thereafter delivered to the purchasers of Shares registered thereby, such registration statement or prospectus will not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading;

(v) furnish counsel for each underwriter, if any, and for the Carlyle Stockholders copies of any correspondence with the SEC or any state securities authority relating to the registration statement or prospectus;

(vi) otherwise comply with all applicable rules and regulations of the SEC, including making available to its security holders an earnings statement covering at least 12 months which shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar provision then in force);

(vii) use all reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of a registration statement at the earliest possible time;

(c) Non-Shelf Registered Offerings and Shelf Takedowns. In connection with any non-shelf registered offering or shelf takedown that is demanded by Carlyle Stockholders or as to which piggyback rights otherwise apply, the Company will:

(i) cooperate with the selling Carlyle Stockholders and the sole underwriter or managing underwriter of an underwritten offering Shares, if any, to facilitate the timely preparation and delivery of certificates representing the Shares to be sold; and enable such Shares to be in such denominations (consistent with the provisions of the governing documents thereof) and registered in such names as the selling Carlyle Stockholders or the sole underwriter or managing underwriter of an underwritten offering of Shares, if any, may reasonably request;

(ii) furnish to each Carlyle Stockholder and to each underwriter, if any, participating in the relevant offering, without charge, as many copies of the applicable prospectus, including each preliminary prospectus, and any amendment or supplement thereto and such other documents as such Carlyle Stockholder or underwriter may reasonably request in order to facilitate the public sale or other disposition of the Shares; the Company hereby consents to the use of the prospectus, including each preliminary prospectus or prospectus supplement, by each such Carlyle Stockholder and underwriter in connection with the offering and sale of the Shares covered by the prospectus, the preliminary prospectus or prospectus supplement;

(iii) (i) use all reasonable efforts to register or qualify the Shares being offered and sold, no later than the time the applicable registration statement becomes effective, under all applicable state securities or “blue sky” laws of such

B-8

jurisdictions as each underwriter, if any, or any Carlyle Stockholder holding Shares covered by a registration statement, shall reasonably request; (ii) use all reasonable efforts to keep each such registration or qualification effective during the period such registration statement is required to be kept effective; (iii) comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement during such period in accordance with the intended methods of disposition by the sellers thereof set forth in the registration statement and (iv) do any and all other acts and things which may be reasonably necessary or advisable to enable each such underwriter, if any, and Carlyle Stockholder to consummate the disposition in each such jurisdiction of such Shares owned by such Carlyle Stockholder; provided, however, that the Company shall not be obligated to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to consent to be subject to general service of process (other than service of process in connection with such registration or qualification or any sale of Shares in connection therewith) in any such jurisdiction where it would not otherwise be required to qualify but for this subparagraph (iv) or subject itself to taxation in any such jurisdiction;

(iv) use commercially reasonable efforts to (i) cause all Shares being sold to be qualified for inclusion in or listed on Nasdaq or any other U.S. securities exchange on which Shares issued by the Company are then so qualified or listed, (ii) comply (and continue to comply) with the requirements of any self-regulatory organization applicable to the Company, including without limitation all corporate governance requirements, (iii) use its best efforts to cause Shares covered by such registration statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the sellers thereof to consummate the disposition of such Shares and (iv) use best efforts to provide a transfer agent and registrar for all Shares to be sold by the Carlyle Stockholders not later than the effective date of such registration statement;

(v) cooperate and assist in any filings required to be made with FINRA and in the performance of any due diligence investigation by any underwriter in an underwritten offering;

(vi) use all reasonable efforts to facilitate the distribution and sale of any Shares to be offered pursuant to this Agreement, including without limitation by making road show presentations, holding meetings with and making calls to potential investors and taking such other actions as shall be requested by the Carlyle Stockholders or the lead managing underwriter of an underwritten offering;

(vii) enter into customary agreements (including, in the case of an underwritten offering, underwriting agreements in customary form, and including provisions with respect to indemnification and contribution in customary form and consistent with the provisions relating to indemnification and contribution contained herein) and take all other customary and appropriate actions in order to expedite or facilitate the disposition of such Shares in connection therewith, including:

(1) make such representations and warranties to the selling Carlyle Stockholders and the underwriters, if any, in form, substance and scope as are customarily made by issuers to underwriters in similar underwritten offerings;

(2) obtain opinions of counsel to the Company in all relevant jurisdictions and updates thereof (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to the lead managing underwriter, if any) addressed to each selling Carlyle Stockholder and the underwriters, if any, covering the matters and jurisdictions customarily covered in opinions requested in sales of securities or underwritten offerings and such other matters as may be reasonably requested by such Carlyle Stockholders and underwriters;

(3) obtain “cold comfort” letters and updates thereof from the Company’s independent certified public accountants addressed to the selling Carlyle Stockholders, if permissible, and the underwriters, if any, which letters shall be customary in form and shall cover matters of the type customarily covered in “cold comfort” letters to underwriters in connection with primary underwritten offerings;

(4) to the extent requested by the Carlyle Stockholders, cause the Company’s directors and executive officers to enter into lock-up agreements in customary form; and

(5) to the extent requested and customary for the relevant transaction, enter into a securities sales agreement with the Carlyle Stockholders providing for, among other things, the appointment of such representative as agent for the selling Carlyle Stockholders for the purpose of soliciting purchases of Shares, which agreement shall be customary in form, substance and scope and shall contain customary representations, warranties and covenants.

The above shall be done at such times as customarily occur in similar registered offerings or shelf takedowns.

B-9

(viii) take all actions to ensure that any free writing prospectus utilized in connection with any registration or offering hereunder complies in all material respects with the Securities Act in relation to the circulation of a prospectus, is filed in accordance with the Securities Act, is retained in accordance with the Securities Act and, when taken together with the related prospectus, prospectus supplement and related documents, will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

(ix) permit any Carlyle Stockholder that, in its sole exclusive judgment, might be deemed to be an underwriter or a controlling person of the Company, to participate in the preparation of such registrations statement and to allow such Carlyle Stockholder to provide language for insertion therein, in form and substance satisfactory to the Company, which in the reasonable judgment of such Carlyle Stockholder and its counsel should be included;

(x) use best efforts to (i) make Form S-3 available for the sale of Shares and (ii) prevent the issuance of any stop order suspending the effectiveness of a registration statement, or the issuance of any order suspending or preventing the use of any related prospectus or suspending the qualification of any Shares included in such registration statement for sale in any jurisdiction, and in the event any such order is issued, use best efforts to obtain promptly the withdrawal of such order;

(xi) if requested by any managing underwriter and reasonably available, include in any prospectus or prospectus supplement updated financial or business information for the Company’s most recent period or current quarterly period (including estimated results or ranges of results) if required for purposes of marketing the offering in the view of the managing underwriter;

(xii) take no direct or indirect action prohibited by Regulation M under the Exchange Act;

(xiii) cooperate with each Carlyle Stockholder covered by the registration statement and each underwriter or agent participating in the disposition of such Shares and their respective counsel in connection with the preparation and filing of applications, notices, registrations and responses to requests for additional information with FINRA, Nasdaq or any other national securities exchange on which the Shares are or are to be listed, and to the extent required by the rules and regulations of FINRA, retain a Qualified Independent Underwriter acceptable to the managing underwriter;

(xiv) if the Company files an automatic shelf registration statement covering any Shares, use its best efforts to remain a WKSI (and not become an ineligible issuer (as defined in Rule 405 under the Securities Act)) during the period during which such automatic shelf registration statement is required to remain effective;

(xv) if the Company does not pay the filing fee covering the Shares at the time an automatic shelf registration statement is filed, pay such fee at such time or times as the Shares are to be sold;

(xvi) if the automatic shelf registration statement has been outstanding for at least three years, at the end of the third year, refile a new automatic shelf registration statement covering the Shares, and, if at any time when the Company is required to re-evaluate its WKSI status the Company determines that it is not a WKSI, use its best efforts to refile the shelf registration statement on Form S-3 and, if such form is not available, Form S-1 and keep such registration statement effective during the period during which such registration statement is required to be kept effective;

(xvii) if the Company plans to file any automatic shelf registration statement for the benefit of the holders of any of its securities other than the Carlyle Stockholders, and the Carlyle Stockholders do not request that their Shares be included in such shelf registration statement, the Company agrees that, at the request of the Carlyle Majority Interest, include in such automatic shelf registration statement such disclosures as may be required by Rule 430B under the Securities Act in order to ensure that the Carlyle Stockholders may be added to such shelf registration statement at a later time through the filing of a prospectus supplement rather than a post-effective amendment (and if the Company has filed any automatic shelf registration statement for the benefit of the holders of any of its securities other than the Carlyle Stockholders, the Company shall, at the request of the Carlyle Majority Interest, file any post-effective amendments necessary to include therein all disclosure and language necessary to ensure that the Carlyle Stockholders may be added to such Shelf Registration Statement); and

(xviii) with respect to any shelf takedown that is demanded by Carlyle Stockholders, use commercially reasonable efforts to take such actions necessary to facilitate such shelf takedown by the Carlyle Stockholders as soon as possible, and in any event within 72 hours of receipt of notice of any such shelf takedown (but in no event less than two business days after the receipt of such notice) (the “Preparation Period”); provided that the Company agrees that after such Preparation Period, it shall be prepared to cooperate to use commercially reasonable efforts to facilitate such shelf takedown on any trading day during the following 15 business days without requiring an additional Preparation Period;

B-10

provided, further that the Carlyle Stockholders shall use commercially reasonable efforts to provide the Company with at least five business days’ advanced notice of its intention to submit a notice of request for registration.

(d) Due Diligence. In connection with each registration and offering of Shares to be sold by Carlyle Stockholders, the Company will, in accordance with customary practice, make available for inspection by representatives of the Carlyle Stockholders and underwriters and any counsel or accountant retained by such Carlyle Stockholder or underwriters all relevant financial and other records, pertinent corporate documents and properties of the Company and cause appropriate officers, managers and employees of the Company to supply all information reasonably requested by any such representative, underwriter, counsel or accountant in connection with their due diligence exercise.

(e) Information from Stockholders. Each Carlyle Stockholder that holds Shares covered by any registration statement will timely furnish to the Company such information regarding itself as is required to be included in the registration statement, the ownership of Shares by such Carlyle Stockholder and the proposed distribution by such Carlyle Stockholder of such Shares as the Company may from time to time reasonably request in writing.

3.4 Indemnification.

(a) Indemnification by the Company. In the event of any registration under the Securities Act by any registration statement of Shares held by Carlyle Stockholders, the Company will hold harmless Carlyle Stockholders, any such Carlyle Stockholder’s officers, directors, employees, agents, fiduciaries, stockholders, managers, partners, members, affiliates, direct and indirect equityholders, consultants and representatives, and any successors and assigns thereof, and each underwriter of such securities and each other person, if any, who controls any Carlyle Stockholder or such underwriter within the meaning of the Securities Act (collectively, the “Indemnified Parties”), against any losses, claims, actions, damages, liabilities or expenses (including with respect to actions or proceedings, whether commenced or threatened, and including reasonable attorney fees and expenses) (collectively, “Losses”), joint or several, to which Carlyle Stockholders or such underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such Losses arise out of or are based upon (i) any untrue or alleged untrue statement of material fact contained in (A) any registration statement, prospectus, preliminary prospectus or free writing prospectus, or any amendment thereof or supplement thereto or (B) any application or other document or communication (in this Section 3.4, collectively called an “application”) executed by or on behalf of the Company or based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify any securities covered by such registration under the “blue sky” or securities laws thereof, (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any violation or alleged violation by the Company of the Securities Act or any other similar federal or state securities laws or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance; and will reimburse any such Indemnified Party for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such Losses; provided, however, that the Company shall not be liable to any such Indemnified Party in any such case to the extent that any such Losses arise out of or are based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, prospectus, preliminary prospectus or free writing prospectus or any amendment or supplement thereto, or in any application, in reliance upon and in conformity with information furnished to the Company through a written instrument duly executed by such Indemnified Party specifically for use in the preparation thereof.

(b) Indemnification by Carlyle Stockholders. Each Carlyle Stockholder will indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 3.4(a)) the Company, its officers, directors, employees, agents and representatives, and each Person who controls the Company (within the meaning of the Securities Act), with respect to Losses (as determined by a final and unappealable judgment, order or decree of a court of competent jurisdiction) arising from (i) any statement or omission from such registration statement, or any amendment or supplement to it, if such statement or omission was made in reliance upon and in conformity with information furnished to the Company through a written instrument duly executed by such Carlyle Stockholder specifically regarding such Carlyle Stockholder for use in the preparation of such registration statement or amendment or supplement, and (ii) compliance by such Carlyle Stockholder with applicable laws in effecting the sale or other disposition of the securities covered by such registration statement.

(c) Indemnification Procedures. Promptly after receipt by an indemnified party of notice of the commencement of any action involving a claim referred to in Section 3.4(a) and Section 3.4(b), the indemnified party will, if a resulting claim is to be made or may be made against and indemnifying party, give written notice to the indemnifying party of the

B-11

commencement of the action. The failure of any indemnified party to give notice shall not relieve the indemnifying party of its obligations in this Section 3.4, except to the extent that the indemnifying party is actually prejudiced by the failure to give notice. If any such action is brought against an indemnified party, the indemnifying party will be entitled to participate in and to assume the defense of the action with counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to such indemnified party of its election to assume defense of the action, the indemnifying party will not be liable to such indemnified party for any legal or other expenses incurred by the latter in connection with the action’s defense. An indemnified party shall have the right to employ separate counsel in any action or proceeding and participate in the defense thereof, but the fees and expenses of such counsel shall be at such indemnified party’s expense unless (i) the employment of such counsel has been specifically authorized in writing by the indemnifying party, which authorization shall not be unreasonably withheld, (ii) the indemnifying party has not assumed the defense and employed counsel reasonably satisfactory to the indemnified party within 30 days after notice of any such action or proceeding, or (iii) the named parties to any such action or proceeding (including any impleaded parties) include the indemnified party and the indemnifying party and the indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to the indemnified party that are different from or additional to those available to the indemnifying party (in which case the indemnifying party shall not have the right to assume the defense of such action or proceeding on behalf of the indemnified party), it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to all local counsel which is necessary, in the good faith opinion of both counsel for the indemnifying party and counsel for the indemnified party in order to adequately represent the indemnified parties) for the indemnified party and that all such fees and expenses shall be reimbursed as they are incurred upon written request and presentation of invoices. Whether or not a defense is assumed by the indemnifying party, the indemnifying party will not be subject to any liability for any settlement made without its consent (such consent not to be unreasonably withheld, delayed or conditioned). No indemnifying party will consent to entry of any judgment or enter into any settlement which (i) does not include as an unconditional term the giving by the claimant or plaintiff, to the indemnified party, of a release from all liability in respect of such claim or litigation or (ii) involves the imposition of equitable remedies or the imposition of any non-financial obligations on the indemnified party.

(d) Contribution. If the indemnification required by this Section 3.4 from the indemnifying party is unavailable to or insufficient to hold harmless an indemnified party in respect of any indemnifiable Losses, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such Losses in such proportion as is appropriate to reflect (i) the relative benefit of the indemnifying and indemnified parties and (ii) if the allocation in clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect the relative benefit referred to in clause (i) and also the relative fault of the indemnified and indemnifying parties, in connection with the actions which resulted in such Losses, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and the indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact, has been made by, or relates to information supplied by, such indemnifying party or parties, and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the Losses referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with any investigation or proceeding. The Company and Carlyle Stockholders agree that it would not be just and equitable if contribution pursuant to this Section 3.4(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the prior provisions of this Section 3.4(d). Notwithstanding the provisions of this Section 3.4(d), no Carlyle Stockholder shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale of the securities by such Carlyle Stockholder exceeds the amount of any damages which the indemnifying party has otherwise been required to pay by reason of an untrue statement or omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such a fraudulent misrepresentation.

(e) Non-Exclusive Remedy. The indemnification and contribution provided for under this Agreement will be in addition to any other rights to indemnification or contribution that any indemnified party may have pursuant to law or contract (and the Company and its subsidiaries shall be considered the indemnitors of first resort in all such circumstances to which this Section 3 applies) and will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and will survive the transfer of Shares and the termination or expiration of this Agreement.

3.5 Rule 144. If the Company is subject to the requirements of Section 13, 14 or 15(d) of the Exchange Act, the Company covenants that it will file any reports required to be filed by it under the Securities Act and the Exchange Act (or, if the Company is subject to the requirements of Section 13, 14 or 15(d) of the Exchange Act but is not required to file such reports, it will, upon the request of any Carlyle Stockholder, make publicly available such information) and it will take such further action as any Carlyle Stockholder may reasonably request, so as to enable such Carlyle Stockholder to sell Shares without registration under the Securities Act within the limitation of the exemptions provided by (a) Rule 144 under the Securities Act, as such Rule may be amended from time to time, or (b) any similar rule or regulation hereafter adopted by the SEC. Upon the request of any Carlyle Stockholder, the Company will deliver to such Carlyle Stockholder a written statement as to whether it has complied with such requirements. Furthermore, the Company shall use its reasonable best efforts to facilitate any sale by a Carlyle Stockholder under Rule 144 under the Securities Act, including delivery of any legal opinions and instruction letters required by the Company’s transfer agent and such other documentation as may be reasonably requested by the Carlyle Stockholder or its broker in connection with such sales.

SECTION IV. BOARD OF DIRECTORS MATTERS

4.1 Board of Directors.

(a) The Carlyle Stockholders will have the right to nominate a number of individuals for election to the Board of Directors equal to the Carlyle Board Representation Number (with each of such individuals being nominated by the Initial Carlyle Stockholder and/or such other Carlyle Stockholders as the Initial Carlyle Stockholder shall from time to time designate in writing to the Company) and who are reasonably acceptable to the Board of Directors (each, a “Carlyle Nominee”), provided, that each of Stephen Wise, Robert Schmidt and Allan Holt shall be deemed to be reasonably acceptable for purposes of this Section 4.1(a). For the avoidance of doubt, the Board of Directors may determine that a Carlyle Nominee is not reasonably acceptable if such Carlyle Nominee is a Competing Director.

(b) For so long as the Carlyle Stockholders have the right to nominate any Carlyle Nominee, in connection with each election of Directors, (i) the Company shall nominate each such Carlyle Nominee for election as a Director as part of the slate that is included in the proxy statement (or consent solicitation or similar document) of the Company relating to the election of Directors, and shall provide the highest level of support for the election of each such Carlyle Nominee as it provides to any other individual standing for election as a Director as part of the Company’s slate of Directors, and the Board of Directors shall recommend that the stockholders of the Company elect to the Board of Directors each such Carlyle Nominee, and (ii) the Company shall include in the slate that is included in the proxy statement (or consent solicitation or similar document) of the Company relating to the election of Directors only (A) the Carlyle Nominees nominated by the Carlyle Stockholders in accordance with this Section 4.1(a) and (B) the other Director nominees (if any) nominated by the Board of Directors (or a committee thereof). For so long as the Carlyle Stockholders have the right to nominate any Carlyle Nominee, the Board of Directors (and any committee thereof) shall not nominate (and the Company shall not include in the slate that is included in the proxy statement (or consent solicitation or similar document) of the Company relating to the election of Directors) a number of nominees for any election of Directors that exceeds the total number of Directors. For the avoidance of doubt, without limiting the rights of the Carlyle Stockholders under this Agreement, nothing herein shall prevent the Company from including director nominees submitted by stockholders for inclusion in the Company’s proxy statement under proxy access or similar rules under the Exchange Act.

(c) If, from time to time, the Carlyle Board Representation Number shall decrease, the Carlyle Stockholders and the Company shall take all necessary action to cause the applicable number of Carlyle Nominees to resign or be removed immediately, unless otherwise requested in writing by the Company. Subject to the immediately foregoing sentence, in the event that a Carlyle Nominee shall cease to serve as a Director for any reason (including any removal thereof), the Carlyle Stockholders shall have the right to nominate another Carlyle Nominee to fill any vacancy resulting therefrom. For the avoidance of doubt, it is understood that the failure of the stockholders of the Company to elect any Carlyle Nominee shall not affect the right of the Carlyle Stockholder to designate the Carlyle Nominees for election pursuant to this Section 4.1(c) in connection with any future election of Directors.

(d) Other Board of Directors Matters.

(i) The Company shall reimburse each director nominated by the Carlyle Stockholders for all reasonable out-of-pocket expenses incurred in connection with his or her attendance at meetings of the Board of Directors and any committees thereof, including travel, lodging and meal expenses, subject to the Company’s travel and reimbursement policies that are no less favorable than the policies that apply to other Directors.

B-13

(ii) The Company shall obtain, for each director nominated by the Carlyle Stockholders, customary director and officer indemnity insurance on commercially reasonable terms as determined by the Board of Directors and on terms no less favorable than the director and officer indemnity insurance obtained for other Directors.

(iii) In addition to any other indemnification rights that the directors have pursuant to the certificate of incorporation and the bylaws (or equivalent governing documents) of the Company, each person nominated by the Carlyle Stockholders to serve on the Board of Directors in accordance with this Section 4.1 shall have the right to enter into, and the Company agrees to enter into, an indemnification agreement in a form consistent with indemnification agreements customarily entered into between companies and their independent board members.

(iv) If at any time a Carlyle Nominee serving on the Board of Directors becomes a Competing Director, such Competing Director shall promptly tender his or her resignation to the Board of Directors, provided that the Carlyle Stockholders shall have the right to appoint a new Carlyle Nominee to fill the resulting vacancy, including on any applicable Specified Committee.

SECTION V. CORPORATE OPPORTUNITIES

5.1 Competition and Corporate Opportunities. With respect to competition and corporate opportunities:

(a) In recognition and anticipation that (i) certain directors, principals, officers, employees and/or other representatives of the Initial Carlyle Stockholder may serve as directors, officers or agents of the Company, (ii) the Initial Carlyle Stockholder may now engage and may continue to engage in the same or similar activities or related lines of business as those in which the Company, directly or indirectly, may engage and/or other business activities that overlap with or compete with those in which the Company, directly or indirectly, may engage, and (iii) Carlyle Nominees who are not employees of the Company (“Non-Employee Directors”) and their respective Affiliates may now engage and may continue to engage in the same or similar activities or related lines of business as those in which the Company, directly or indirectly, may (subject to Section 4.1(d)(iv)) engage in and/or other business activities that overlap with or compete with those in which the Company, directly or indirectly, may engage, the provisions of this ARTICLE V are set forth to regulate and define the conduct of certain affairs of the Company with respect to certain classes or categories of business opportunities as they may involve any of the Initial Carlyle Stockholder, the Non-Employee Directors or their respective Affiliates and the powers, rights, duties and liabilities of the Company and its directors, officers and stockholders in connection therewith.

(b) Neither (i) the Initial Carlyle Stockholder nor (ii) any Non-Employee Director (the Persons (as defined below) identified in (i) and (ii) above being referred to, collectively, as “Identified Persons” and, individually, as an “Identified Person”) shall, to the fullest extent permitted by law, have any duty to refrain from directly or indirectly (1) engaging in the same or similar business activities or lines of business in which the Company or any of its Affiliates now engages or proposes to engage or (2) otherwise competing with the Company or any of its Affiliates, and, to the fullest extent permitted by law no Identified Person shall be liable to the Company or its stockholders or to any Affiliate of the Company for breach of any fiduciary duty solely by reason of the fact that such Identified Person engages in any such activities.

(c) To the fullest extent permitted from time to time by the laws of the State of Delaware, the Company hereby renounces any interest or expectancy in, or right to be offered an opportunity to participate in, any business opportunity that may be a corporate opportunity for an Identified Persons and the Company or any of its Affiliates, except as provided in Section 5.1(d). Subject to Section 5.1(d), in the event that any Identified Person acquires knowledge of a potential transaction or other business opportunity that may be a corporate opportunity for itself, herself or himself, or any of its or his or her Affiliates, and the Company or any of its Affiliates, such Identified Person shall, to the fullest extent permitted by law, have no duty to communicate or offer such transaction or other business opportunity to the Company or any of its Affiliates and, to the fullest extent permitted by law, shall not be liable to the Company or its stockholders or to any Affiliate of the Company for breach of any fiduciary duty as a stockholder, director or officer of the Company solely by reason of the fact that such Identified Person pursues or acquires such corporate opportunity for itself, herself or himself, or offers or directs such corporate opportunity to another Person.

(d) Notwithstanding the foregoing, the Company does not renounce its interest in any corporate opportunity offered to any Non-Employee Director (including any Non-Employee Director who serves as an officer of the Company) if such opportunity is expressly offered to such person in his or her capacity as a director or officer of the Company, and the provisions of Section 5.1(d) shall not apply to any such corporate opportunity.

(e) In addition to and notwithstanding the foregoing provisions of this Article V, a corporate opportunity shall not be deemed to be a potential corporate opportunity for the Company if it is a business opportunity that (i) the Company is

B-14

neither financially or legally able, nor contractually permitted to undertake, (ii) from its nature, is not in the line of the Company’s business or is of no practical advantage to the Company or (iii) is one in which the Company has no interest or reasonable expectancy, in each case as determined by the Board of Directors (with the Carlyle Nominees abstaining from any such deliberations or votes)

5.2 Approval of Waiver. Topco hereby (a) represents and warrants to the Initial Carlyle Stockholder that, in accordance with the DGCL, the board of directors of Topco has (i) approved the waiver set forth in the foregoing Section 5.1 and (ii) renounced any interest or expectancy of Topco in , or in being offered an opportunity to participate in, the business opportunities described in Section 5.1, and (b) covenants and agrees that such waiver and renouncement shall not be rescinded, revoked or modified in any manner adverse to any Identified Persons during the term of this Agreement.

6.10 Governing Law.

It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which such party is entitled at law or in equity.

(c) EACH PARTY TO THIS AGREEMENT WAIVES TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY ANY OF THEM AGAINST THE OTHER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS AGREEMENT, OR ANY OTHER AGREEMENTS EXECUTED AND DELIVERED PURSUANT TO OR IN CONNECTION HEREWITH OR THE NEGOTIATION, BREACH, VALIDITY, TERMINATION OR PERFORMANCE HEREOF AND THEREOF OR THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY.

| (b) | after the General Meeting has been held, in circumstances where the GM Resolutions (or any one of them) have not been lawfully passed due to a technical and/or procedural defect(s) being either: (i) on the grounds that the relevant provisions of the Companies Act or applicable Laws have not been complied with; or (ii) a failure to comply with the articles of association or other constitutional documents of Orca, which reasonably appears to be capable of remedy and/or rectification without having any adverse commercial or financial impact for Laguna in its judgement (acting reasonably); or

| (c) | in the event that the English Court does not sanction the Orca Scheme at the Orca Sanction Hearing on the grounds of a technical and/or procedural defect in relation to any aspect of the Orca Scheme or its implementation being a Scheme Technical Defect, or on such other grounds which reasonably appears to be capable of remedy and/or rectification without having any adverse commercial or financial impact for Laguna in its judgement (acting reasonably),

in which case, subject to the terms of the BCA, Laguna and Orca may implement the Transaction (subject to obtaining the necessary shareholder votes) by way of a new, revised or renewed Orca Scheme or a direct contractual offer (or other similar transaction structure), subject to such terms and conditions as further particularised in the Orca Scheme Document.

For the avoidance of doubt, pursuant to the terms of paragraph 3 above, Carlyle shall not direct Computershare to transfer the legal title of any of my Committed Shares other than as specifically required by this paragraph 4.4.

Board of Directors

Quidel Corporation

San Diego, CA 92121

Members of the Board:

We understand that Quidel Corporation, a Delaware corporation (the “Company”), Ortho Clinical Diagnostics Holdings plc, a public limited company incorporated under the laws of England and Wales (“Ortho”), Coronado Topco, Inc., a Delaware corporation and a wholly owned subsidiary of Ortho (“Topco”), Laguna Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Topco (“U.S. Merger Sub”), Orca Holdco, Inc., a Delaware corporation and wholly owned subsidiary of Topco (“U.S. Holdco Sub”), and Orca Holdco 2, Inc., a Delaware corporation and wholly owned subsidiary of U.S. Holdco Sub (“U.S. Holdco Sub 2”), propose to enter into a Business Combination Agreement (the “Business Combination Agreement”) pursuant to which, among other things, (a) Ortho and Topco will undergo a scheme of arrangement (the “Ortho Scheme”) pursuant to which, through a series of transactions, each issued and outstanding ordinary share, par value $0.00001 per share (each, an “Ortho Ordinary Share”), of Ortho, other than any Ortho Ordinary Shares held by Ortho in treasury, will be exchanged for a combination of (i) 0.1055 shares of common stock, par value $0.001 per share (the “Topco Common Stock”), of Topco (the “Stock Consideration”) and (ii) $7.14 in cash (the “Cash Consideration” and, together with the Stock Consideration, the “Consideration”), and as a result of which Ortho will become a wholly owned subsidiary of Topco, and (b) U.S. Merger Sub will merge with and into the Company immediately following consummation of the Ortho Scheme, with the Company surviving the merger as a wholly owned subsidiary of Topco (the “Company Merger” and, together with the Ortho Scheme, the “Combinations”), pursuant to which each share of common stock, par value $0.001 per share, of the Company (the “Company Common Stock”), other than Company Common Stock owned by the Company, Ortho or U.S. Merger Sub, shall be converted into the right to receive one share (the “Company Exchange Ratio”) of Topco Common Stock. The terms and conditions of the Combinations are more fully set forth in the Business Combination Agreement.

You have requested our opinion as to the fairness, from a financial point of view, to the Company of the Consideration to be paid by the Company pursuant to the Business Combination Agreement taking into account the Company Exchange Ratio.

For purposes of the opinion set forth herein, we have, among other things:

1. reviewed certain publicly available financial statements and other business and financial information with respect to the Company and Ortho, including equity research analyst reports;

2. reviewed certain internal financial statements, analyses and forecasts, including sensitivities thereto (the “Company Forecasts”), and other financial and operating data relating to the business of the Company, in each case, prepared by management of the Company;

D-1

3. reviewed certain internal financial statements, analyses and forecasts (the “Ortho Forecasts”), and other financial and operating data relating to the business of Ortho, in each case, prepared by management of Ortho and approved for our use by management of the Company;

4. reviewed certain internal financial statements, analyses and forecasts (the “Company Ortho Forecasts”) relating to the business of Ortho prepared by management of the Company;

5. reviewed estimates of synergies anticipated by the Company’s and Ortho’s management to result from the Combinations (collectively, the “Anticipated Synergies”);

6. discussed the past and current business, operations, financial condition and prospects of the Company, including the Anticipated Synergies, with the management and other representatives of the Company, and discussed the past and current business, operations, financial condition and prospects of Ortho with the management and other representatives of the Company;

7. reviewed the relative financial contributions of the Company and Ortho to the future financial performance of Topco on a pro forma basis;

8. compared the financial performance of the Company and Ortho with that of certain other publicly traded companies which we believe to be generally relevant;

9. compared the financial terms of the proposed Combinations with the publicly available financial terms of certain transactions which we believe to be generally relevant;

10. reviewed the historical trading prices and trading activity for the Company Common Stock and Ortho Ordinary Shares, and compared such prices and trading activity of the Company Common Stock and Ortho Ordinary Shares with those of securities of certain other publicly traded companies which we believe to be generally relevant;

11. participated in discussions among representatives of the Company and Ortho and their respective advisors;

12. reviewed a draft, dated December 22, 2021, of the Business Combination Agreement; and

13. conducted such other financial studies, analyses and investigations, and considered such other factors, as we have deemed appropriate.

In arriving at our opinion, we have assumed and relied upon, without independent verification, the accuracy and completeness of the financial and other information supplied or otherwise made available to us (including information that is available from generally recognized public sources) for purposes of this opinion and have further relied upon the assurances of the management of the Company that, to their knowledge, the information furnished, or approved for our use, by them for purposes of our analysis does not contain any material omissions or misstatements of material fact. With respect to the Company Forecasts, we have been advised by the management of the Company, and have assumed, with your consent, that they have been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of the Company as to the future stand-alone financial performance of the Company and the other matters covered thereby and we express no view as to the assumptions on which they are based. With respect to the Ortho Forecasts, we have assumed, with your consent, that they have been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of Ortho as to the future stand-alone financial performance of Ortho and the other matters covered thereby and we express no view as to the assumptions on which they are based. With respect to the Company Ortho Forecasts, we have assumed, with your consent, that they have been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of the Company as to the future stand-alone financial performance of Ortho and the other matters covered thereby and we express no view as to the assumptions on which they are based. We have assumed, with your consent, that the Anticipated Synergies and potential strategic implications and operational benefits (including the amount, timing and achievability thereof) anticipated by management of the Company to result from the Combinations will be realized in the amounts and at the times projected by management of the Company, and we express no view as to the assumptions on which they are based. We have

www.pwpartners.com

Partners have limited liability status

D-2

relied without independent verification upon the assessment by the management of the Company of the timing and risks associated with the integration of the Company and Ortho. In arriving at our opinion, we have not made any independent valuation or appraisal of the assets or liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of the Company or Ortho, nor have we been furnished with any such valuations or appraisals. We have not assumed any obligation to conduct, nor have we conducted, any physical inspection of the properties or facilities of the Company or Ortho. In addition, we have not evaluated the solvency of any party to the Business Combination Agreement (or the impact of the Combinations thereon), including under any applicable laws relating to bankruptcy, insolvency or similar matters. We have assumed that the final executed Business Combination Agreement will not differ from the form of the Business Combination Agreement reviewed by us in any respect material to our analysis, and that the Combinations will be consummated in accordance with the terms set forth in the Business Combination Agreement, without modification, waiver or delay in any respect material to our analysis. We also have assumed that the Company Merger and the Ortho Scheme, taken together as a single integrated transaction, will qualify as an exchange described under Section 351 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”) and that the Company Merger will also qualify as a “reorganization” within the meaning of Section 368(a) of the Code. In addition, we have assumed that in connection with the receipt of all the necessary approvals for the Combinations, no delays, limitations, conditions or restrictions will be imposed that could have an adverse effect on the Company, Ortho or the contemplated benefits expected to be derived in the proposed Combinations, in each case, in any way meaningful to our analysis. We have relied as to all legal matters relevant to rendering our opinion upon the advice of counsel.

This opinion addresses only the fairness from a financial point of view, as of the date hereof, of the Consideration provided for in the Business Combination Agreement to the Company taking into account the Company Exchange Ratio. We have not been asked to, nor do we, offer any opinion as to any other term of the Business Combination Agreement or any other document contemplated by or to be entered into in connection with the Business Combination Agreement or the form or structure of the Combinations or the likely timeframe in which the Combinations will be consummated. In addition, we express no opinion as to the fairness of the amount or nature of any compensation to be received by any officers, directors or employees of any parties to the Business Combination Agreement, or any class of such persons, whether relative to the Consideration or otherwise. We do not express any opinion as to any tax or other consequences that may result from the transactions contemplated by the Business Combination Agreement or any related document, nor does our opinion address any legal, tax, regulatory or accounting matters, as to which we understand the Company has received such advice as it deems necessary from qualified professionals. Our opinion does not address the underlying business decision by the Company to enter into the Business Combination Agreement or the relative merits of the Combinations as compared with any other strategic alternative which may be available to the Company. We have not been authorized to solicit, and have not solicited, indications of interest in a transaction with the Company from any party.

We have acted as financial advisor to the Company in connection with the Combinations and will receive a fee for our services, a portion of which is payable upon the rendering of this opinion (or would have become payable if we had determined that we were not able to deliver this opinion) and a significant portion of which is contingent upon the consummation of the Combinations. In addition, the Company has agreed to reimburse us for certain expenses that may arise, and indemnify us for certain liabilities and other items that may arise, out of our engagement. During the two year period prior to the date hereof, no material relationship existed between Perella Weinberg Partners LP and its corporate advisory affiliates and Ortho pursuant to which compensation was received by Perella Weinberg Partners LP or its corporate advisory affiliates. In the past, Perella Weinberg Partners LP and its corporate advisory affiliates have provided financial advisory services unrelated to the Combinations to The Carlyle Group, a controlling shareholder of Ortho, or its affiliates pursuant to which compensation was received by Perella Weinberg Partners LP or its affiliates. In the past, Perella Weinberg Partners LP and its affiliates have provided financial advisory and other financial services to the Company and its affiliates unrelated to the Combinations, for which they have received compensation. Perella Weinberg Partners LP and its corporate advisory affiliates in the future may provide investment banking and other financial services to the Company, Ortho, The Carlyle Group and their respective affiliates and in the future may receive compensation for the rendering of such services. In the ordinary course of our business activities, Perella

Weinberg Partners LP or its affiliates may at any time hold long or short positions, and may trade or otherwise effect transactions, for our own account or the accounts of customers or clients, in debt or equity or other securities (or related derivative securities) or financial instruments (including bank loans or other obligations) of the Company, Ortho, The Carlyle Group or any of their respective affiliates. The issuance of this opinion was approved by a fairness opinion committee of Perella Weinberg Partners LP.

This opinion is for the information and assistance of the Board of Directors of the Company in connection with, and for the purposes of its evaluation of, the Combinations. This opinion is not intended to be and does not constitute a recommendation to any holder of Company Common Stock or Ortho Ordinary Shares, or any other person, as to how such person should vote or otherwise act with respect to the proposed Combinations or any other matter and does not in any manner address the prices at which the Company Common Stock, the Ortho Ordinary Shares or the Topco Common Stock will trade at any time. In addition, we express no opinion as to the fairness of the Combinations to, or any consideration received in connection with the Combinations by, the holders of any other class of securities, creditors or other constituencies of the Company.

Our opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. It should be understood that subsequent developments may affect this opinion and the assumptions used in preparing it, and we do not have any obligation to update, revise, or reaffirm this opinion.

Based upon and subject to the foregoing, including the various assumptions and limitations set forth herein, we are of the opinion that, taking into account the Company Exchange Ratio, as of the date hereof, the Consideration to be paid by the Company pursuant to the Business Combination Agreement is fair, from a financial point of view, to the Company.

Very truly yours,

Members of the Board of Directors:

You have requested our opinion as to the fairness, from a financial point of view, to the holders of shares, par value $0.00001 per share (the “Company Shares”), of Ortho Clinical Diagnostics Holdings plc (the “Company”), a public limited company incorporated under the laws of England and Wales, of the consideration to be paid to such holders in the proposed Transaction (as defined below). Pursuant to the Business Combination Agreement, dated as of December 22, 2021 (the “Agreement”), among Quidel Corporation (the “Merger Partner”), a Delaware corporation, Coronado Topco, Inc. (“Topco”), a Delaware corporation and wholly owned subsidiary of the Company, Laguna Merger Sub, Inc. (“Merger Subsidiary”), a Delaware corporation and wholly owned subsidiary of Topco, Orca Holdco, Inc. (“Holdco Subsidiary”) a Delaware corporation and a wholly owned subsidiary of Topco, Orca Holdco 2, Inc. (“Holdco Subsidiary 2”), a Delaware corporation and a wholly owned subsidiary of Holdco Subsidiary, and the Company, (i) the Company and Topco will effect a scheme of arrangement, in accordance with the laws of England and Wales (the “Company Scheme”), upon the consummation of which each Company Share, other than Company Shares held in treasury, will be acquired by (or transferred within) a nominee on behalf of Topco in exchange for the right to receive consideration per share equal to $7.14 in cash (the “Cash Consideration”) and 0.1055 shares (the “Stock Consideration”, and together with the Cash Consideration, the “Consideration”) of common stock, par value $0.001 per share, of Topco (the “Topco Common Stock”), such that the Company will become a wholly owned subsidiary of Topco and (ii) immediately following the Company Scheme, Merger Subsidiary will merge with and into the Merger Partner, with the Merger Partner surviving the merger as a wholly owned subsidiary of Topco, and each share of common stock of the Merger Partner, par value $0.001 per share (the “Merger Partner Shares”), other than Merger Partner Shares owned by the Merger Partner, the Company, Topco, Merger Subsidiary or any of their respective wholly owned subsidiaries, will be converted into the right to receive one share of Topco Common Stock (the transactions described in clauses (i) and (ii), collectively, the “Transaction”).

In connection with preparing our opinion, we have (i) reviewed the Agreement; (ii) reviewed certain publicly available business and financial information concerning the Company and the Merger Partner and the industries in which they operate; (iii) compared the financial and operating performance of the Company and the Merger Partner with publicly available information concerning certain other companies we deemed relevant and reviewed the current and historical market prices of the Company Shares and the Merger Partner Shares and certain publicly traded securities of such other companies; (iv) reviewed certain internal financial analyses and forecasts prepared by the management of the Company relating to its business and the Merger Partner’s business, as well as the estimated amount and timing of the cost savings and related expenses and synergies expected to result from the Transaction (the “Synergies”); and (v) performed such other financial studies and analyses and considered such other information as we deemed appropriate for the purposes of this opinion.

In addition, we have held discussions with certain members of the management of the Company and the Merger Partner with respect to certain aspects of the Transaction, and the past and current business operations of the Company and the Merger Partner, the financial condition and future prospects and operations of the Company, the Merger Partner and Topco, the effects of the Transaction on the financial condition and future prospects of the Company, the Merger Partner and Topco, and certain other matters we believed necessary or appropriate to our inquiry.

In giving our opinion, we have relied upon and assumed the accuracy and completeness of all information that was publicly available or was furnished to or discussed with us by the Company and the Merger Partner or otherwise reviewed by or for us. We have not independently verified any such information or its accuracy or completeness and, pursuant to our engagement letter with the Company, we did not assume any obligation to undertake any such independent verification. We have not conducted or been provided with any valuation or appraisal of any assets or liabilities, nor have we evaluated the solvency of the Company, the Merger Partner or Topco under any state or federal laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to us or derived therefrom, including the Synergies, we have assumed that they have been reasonably prepared based on assumptions reflecting the best currently available

E-1

estimates and judgments by management as to the expected future results of operations and financial condition of the Company and the Merger Partner to which such analyses or forecasts relate. We express no view as to such analyses or forecasts (including the Synergies) or the assumptions on which they were based. We have also assumed that the Transaction and the other transactions contemplated by the Agreement will qualify as a tax-free reorganization for United States federal income tax purposes, and will be consummated as described in the Agreement. We have also assumed that the representations and warranties made by the Company and the Merger Partner in the Agreement and the related agreements are and will be true and correct in all respects material to our analysis. We are not legal, regulatory or tax experts and have relied on the assessments made by advisors to the Company with respect to such issues. We have further assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Company, the Merger Partner or Topco or on the contemplated benefits of the Transaction, in each case, that would be material to our analysis.

Our opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. It should be understood that subsequent developments may affect this opinion and that we do not have any obligation to update, revise, or reaffirm this opinion. Our opinion is limited to the fairness, from a financial point of view, of the Consideration to be paid to the holders of the Company Shares in the proposed Transaction and we express no opinion as to the fairness of any consideration to be paid in connection with the Transaction to the holders of any other class of securities, creditors or other constituencies of the Company or as to the underlying decision by the Company to engage in the Transaction. Furthermore, we express no opinion with respect to the amount or nature of any compensation to any officers, directors, or employees of any party to the Transaction, or any class of such persons relative to the Consideration to be paid to the holders of the Company Shares in the Transaction or with respect to the fairness of any such compensation. We are expressing no opinion herein as to the price at which the Company Shares, the Merger Partner Shares or shares of Topco Common Stock will trade at any future time.

We note that we were not authorized to and did not solicit any expressions of interest from any other parties with respect to the sale of all or any part of the Company or any other alternative transaction.

We have acted as financial advisor to the Company with respect to the proposed Transaction and will receive a fee from the Company for our services, a substantial portion of which will become payable only if the proposed Transaction is consummated. In addition, the Company has agreed to indemnify us for certain liabilities arising out of our engagement. During the two years preceding the date of this letter, we and our affiliates have had commercial or investment banking relationships with the Company, for which we and such affiliates have received customary compensation. Such services during such period have included acting as joint lead bookrunner on offerings of debt securities of Company subsidiaries in May 2020 and January 2020, and joint lead bookrunner on offerings of the Company’s equity securities in September 2021 and January 2021. During the two years preceding the date of this letter, we and our affiliates have had commercial or investment banking relationships with The Carlyle Group Inc. (“Carlyle”), the Company’s approximately 50% shareholder, for which we and such affiliates have received customary compensation. Such services during such period have included acting as joint lead bookrunner on an offering of debt securities of a Carlyle subsidiary in May 2021. In addition, during the two years preceding the date of this letter, we and our affiliates have had commercial or investment banking relationships with Carlyle portfolio companies for which we and such affiliates have received customary compensation. Such services during such period have included providing debt syndication, equity underwriting, debt underwriting and financial advisory services to Carlyle portfolio companies. Our commercial banking affiliate is an agent bank and a lender under outstanding credit facilities of Carlyle and Carlyle portfolio companies for which it receives customary compensation or other financial benefits. Please be advised that during the two years preceding the date of this letter, neither we nor our affiliates have had any material financial advisory or other material commercial or investment banking relationships with the Merger Partner. In addition, we and our affiliates hold, on a proprietary basis, less than 1% of the outstanding shares of each of the Company, Carlyle and the Merger Partner. In the ordinary course of our businesses, we and our affiliates may actively trade the debt and equity securities or financial instruments (including derivatives, bank loans or other obligations) of the Company, Carlyle or the Merger Partner for our own account or for the accounts of customers and, accordingly, we may at any time hold long or short positions in such securities or other financial instruments.

On the basis of and subject to the foregoing, it is our opinion as of the date hereof that the Consideration to be paid to the holders of the Company Shares in the proposed Transaction is fair, from a financial point of view, to such holders.

The issuance of this opinion has been approved by a fairness opinion committee of J.P. Morgan Securities LLC. This letter is provided to the Board of Directors of the Company (in its capacity as such) in connection with and for the purposes of its

E-2

evaluation of the Transaction. This opinion does not constitute a recommendation to any shareholder of the Company as to how such shareholder should vote with respect to the Transaction or any other matter. This opinion may not be disclosed, referred to, or communicated (in whole or in part) to any third party for any purpose whatsoever except with our prior written approval. This opinion may be reproduced in full in any registration, proxy or information statement mailed to shareholders of the Company but may not otherwise be disclosed publicly in any manner without our prior written approval.

Very truly yours,

5. | COMPANY NAME

6. | MEMBERS’ RESERVE POWER

6.1 | The members may, by special resolution, direct the directors to take, or refrain from taking, specified action.

7. | DIRECTORS MAY DELEGATE

7.1 | Subject to the Articles, the directors may delegate any of the powers which are conferred on them under the Articles:

| (a) | to such person or committee;

| (b) | by such means (including by power of attorney);

| (c) | to such an extent;

| (d) | in relation to such matters or territories; and

| (e) | on such terms and conditions,

as they think fit.

DECISION-MAKING BY DIRECTORS

9. | DIRECTORS TO TAKE DECISIONS COLLECTIVELY

9.1 | The general rule about decision-making by directors is that any decision of the directors must be either a majority decision at a meeting or a decision taken in accordance with Article 10.

9.2 | If:

| (a) | the Company only has one director for the time being; and

| (b) | no provision of the Articles requires it to have more than one director,

F-iii

the general rule does not apply, and the director may (for so long as he remains the sole director) take decisions without regard to any of the provisions of the Articles relating to directors’ decision-making.

10. | UNANIMOUS DECISIONS

10.1 | A decision of the directors is taken in accordance with this Article 10 when all eligible directors indicate to each other by any means that they share a common view on a matter.

10.2 | Such a decision may take the form of a resolution in writing, signed by each eligible director (whether or not each signs the same document) or to which each eligible director has otherwise indicated agreement in writing.

10.3 | References in these Articles to an “eligible director” means a director who would have been entitled to vote on the relevant matter had it been proposed as a resolution at a directors’ meeting and whose vote would have been counted in respect of such matter.

10.4 | A decision may not be taken in accordance with this Article 10 if the eligible directors would not have formed a quorum at such a meeting.

11. | CALLING A DIRECTORS’ MEETING

11.1 | Any director may call a directors’ meeting by giving notice of the meeting to the directors or by authorising the company secretary (if any) to give such notice.

11.2 | Notice of any directors’ meeting must indicate:

| (a) | its proposed date and time;

| (b) | where it is to take place; and

| (c) | if it is anticipated that directors participating in the meeting will not be in the same place, how it is proposed that they should communicate with each other during the meeting.

11.3 | Subject to Article 11.4, notice of a directors’ meeting must be given to each director whether or not he is absent from the United Kingdom, but need not be in writing.

11.4 | Notice of a directors’ meeting need not be given to directors who waive their entitlement to notice of that meeting, by giving notice to that effect to the Company prior to or not more than seven days after the date on which the meeting is held. Where such notice is given after the meeting has been held, that does not affect the validity of the meeting, or of any business conducted at it.

12. | PARTICIPATION IN DIRECTORS’ MEETINGS

12.1 | Subject to the Articles, directors participate in a directors’ meeting, or part of a directors’ meeting, when:

| (a) | the meeting has been called and takes place in accordance with the Articles; and

| (b) | they can each communicate to the others any information or opinions they have on any particular item of the business of the meeting.

12.2 | In determining whether directors are participating in a directors’ meeting, it is irrelevant where any director is or how they communicate with each other.

12.3 | If all the directors participating in a meeting are not in the same place, they may decide that the meeting is to be treated as taking place wherever any of them is.

13. | QUORUM FOR DIRECTORS’ MEETINGS

13.1 | At a directors’ meeting, unless a quorum is participating, no proposal is to be voted on, except a proposal to call another meeting.

13.2 | Subject to Article 13.3 and save in the case where there is only one director in office, the quorum for the transaction of business at a meeting of the directors is any two eligible directors.

F-iv

13.3 | For the purposes of any meeting (or part of a meeting) held pursuant to Article 17 to authorise a director’s conflict of interest, where there is only one director in office who is not party to the relevant conflict, the quorum for such meeting (or part of a meeting) shall be one eligible director.

13.4 | If the total number of directors for the time being is less than the quorum required, the directors must not take any decision other than a decision:

| (a) | to appoint further directors; or

| (b) | to call a general meeting so as to enable the members to appoint further directors.

14. | CHAIRING OF DIRECTORS’ MEETINGS

14.1 | The directors may appoint a director to chair their meetings. The person so appointed for the time being is known as the chairman.

14.2 | The directors may terminate the chairman’s appointment at any time.

14.3 | If the chairman is not participating in a directors’ meeting within ten minutes after the time at which it was to start, or if no director has been appointed chairman, the participating directors must appoint one of themselves to chair it.

15. | CASTING VOTE

15.1 | Subject to Article 15.2 if the numbers of votes for and against a proposal at a meeting of directors are equal, the chairman or other director chairing the meeting has a casting vote.

15.2 | The chairman or other director chairing a meeting (or part of a meeting) shall not have a casting vote if, in accordance with the Articles, the chairman, or other director, is not an eligible director for the purposes of that meeting (or part of a meeting).

16. | DIRECTORS’ INTERESTS

16.1 | A director who is in any way, directly or indirectly, interested in a proposed transaction or arrangement with the Company shall declare the nature and extent of his interest to the other directors before the Company enters into the transaction or arrangement.

16.2 | A director who is in any way, directly or indirectly, interested in a transaction or arrangement that has been entered into by the Company shall declare the nature and extent of his interest to the other directors as soon as is reasonably practicable, unless the interest has already been declared under Article 16.1.

16.3 | Any declaration required by Article 16.1 may (but need not) be made, and any declaration required by Article 16.2 must be made, either:

| (a) | at a directors’ meeting;

| (b) | by notice in writing in accordance with section 184 of the Companies Act 2006; or

| (c) | by general notice in accordance with section 185 of the Companies Act 2006.

16.4 | If a declaration made under Article 16.1 or 16.2 proves to be, or becomes, inaccurate or incomplete, a further declaration must be made under Article 16.1 or 16.2, as appropriate.

16.5 | A director need not declare an interest under Article 16.1 or 16.2:

| (a) | if it cannot reasonably be regarded as likely to give rise to a conflict of interest;

| (b) | if, or to the extent that, the other directors are already aware of it (and for this purpose the other directors are treated as aware of anything of which they ought reasonably to be aware);

| (c) | if, or to the extent that, it concerns terms of his service contract that have been or are to be considered by a directors’ meeting or by a committee of the directors appointed for the purpose under these Articles or any agreement between the members; or

| (d) | if the director is not aware of his interest or is not aware of the transaction or arrangement in question (and for this purpose a director is treated as being aware of matters of which he ought reasonably to be aware).

F-v

16.6 | Subject to the provisions of the Companies Act 2006 and provided that he has declared the nature and extent of any direct or indirect interest of his in accordance with Article 16.1 or 16.2, a director notwithstanding his office:

| (a) | may be a party to, or otherwise be interested in, any transaction or arrangement with the Company or in which the Company is otherwise (directly or indirectly) interested;

| (b) | shall be entitled to vote at a meeting of directors (or of a committee of the directors) or participate in any unanimous decision, in respect of such existing or proposed transaction or arrangement in which he is interested (and shall be an eligible director for these purposes);

| (c) | may act by himself or through his firm in a professional capacity for the Company (otherwise than as auditor), and in any such case on such terms as to remuneration and otherwise as the directors may decide; and

| (d) | may be a director or other officer of, or employed or engaged by, or a party to any transaction or arrangement with, or otherwise be interested in, any body corporate in which the Company is otherwise (directly or indirectly) interested.

17. | CONFLICTS OF INTEREST

17.1 | A director, notwithstanding his office, may at the time of his appointment or subsequently be a director or other officer of, employed by, or otherwise interested (including by the holding of shares) in, any subsidiary of the Company, any holding company of the Company, or any subsidiary of a holding company of the Company, from time to time, and no further authorisation under Article 17.2 or 17.3 shall be necessary in respect of such interest.

17.2 | The directors may authorise any matter proposed to them which would, if not so authorised, involve a breach of duty by a director under section 175 of the Companies Act 2006 (and such authorisation may be given on such terms as the directors think fit and may be varied or terminated at any time), provided that any authorisation given under this Article 17.2 shall be effective only if:

| (a) | any requirement as to the quorum at the meeting at which the matter is considered is met without counting the director in question or any other director interested in the matter under consideration; and

| (b) | the matter was agreed to without such directors voting or would have been agreed to if such directors’ votes had not been counted.

17.3 | Alternatively and without prejudice to the remainder of these Articles or the Companies Act 2006, the Company may authorise (specifically or generally) any matter proposed to it which would, if not so authorised, involve a breach of duty by a director under section 175 of the Companies Act 2006. Such authorisation shall be effected:

| (a) | with the consent in writing of the holders of a majority in nominal value of the issued ordinary share capital for the time being of the Company; or

| (b) | by an ordinary resolution.

17.4 | A director shall be under no duty to the Company with respect to any information which he obtains or has obtained otherwise than as a director of the Company and in respect of which he owes a duty of confidentiality to another person. In particular the director shall not be in breach of the general duties he owes to the Company by virtue of sections 171 to 177 of the Companies Act 2006 if he:

| (a) | fails to disclose any such information to the directors or to any director or other officer or employee of, or consultant to, the Company; or

| (b) | does not use or apply any such information in performing his duties as a director of the Company.

However, to the extent that his relationship with that other person gives rise to a conflict of interest or possible conflict of interest, this Article 17.4 applies only if the existence of that relationship has been authorised pursuant to Article 17.1, or authorised by the directors pursuant to Article 17.2, or authorised by the members pursuant to Article 17.3 (and, in each case, subject to the terms upon which such authorisation was given).

17.5 | Where the existence of a director’s relationship with another person has been authorised pursuant to Article 17.1, or authorised by the directors pursuant to Article 17.2, or authorised by the members pursuant to Article 17.3, and his relationship with that person gives rise to a conflict of interest or possible conflict of interest, the director shall not be

F-vi

| in breach of the general duties he owes to the Company by virtue of sections 171 to 177 of the Companies Act 2006 if, at his discretion or at the request or direction of the directors or any committee of the directors, he:

| (a) | absents himself from a directors’ meeting (or a committee thereof) at which any matter relating to the conflict of interest or possible conflict of interest will or may be discussed, or from the discussion of any such matter at a directors’ meeting or otherwise; or

| (b) | makes arrangements not to receive documents and information relating to any matter which gives rise to the conflict of interest or possible conflict of interest sent or supplied by or on behalf of the Company or for such documents and information to be received and read by a professional adviser on his behalf,

for so long as he reasonably believes such conflict of interest (or possible conflict of interest) subsists.

17.6 | The provisions of Articles 17.4 and 17.5 are without prejudice to any equitable principle or rule of law which may excuse the director from:

| (a) | disclosing information, in circumstances where disclosure would otherwise be required under these Articles or any agreement between the members; or

| (b) | attending meetings or discussions or receiving documents and information as referred to in Article 17.5, in circumstances where such attendance or receipt would otherwise be required under these Articles or any agreement between the members.

17.7 | A director shall not, by reason of his office, be accountable to the Company for any remuneration or other benefit which he derives from any office, employment or engagement or from any transaction or arrangement or from any interest in any body corporate:

| (a) | the acceptance, entry into or existence of which is authorised pursuant to Article 17.1, or authorised by the directors pursuant to Article 17.2, or authorised by the members pursuant to Article 17.3 (in each case, subject to the terms upon which such authorisation was given); or

| (b) | which he is permitted to hold or enter into pursuant to Article 16.6 or otherwise pursuant to these Articles or any agreement between the members,

and no such transaction, arrangement or interest shall be liable to be avoided on the ground of any such remuneration or other benefit, nor shall the receipt of any such remuneration or other benefit constitute a breach of his duty under section 176 of the Companies Act 2006.

18. | RECORDS OF DECISIONS TO BE KEPT

The directors must ensure that the Company keeps a record, in writing, for at least 10 years from the date of the decision recorded, of every unanimous or majority decision taken by the directors.

19. | DIRECTORS’ DISCRETION TO MAKE FURTHER RULES

DIVIDENDS AND OTHER DISTRIBUTIONS

37. | PROCEDURE FOR DECLARING DIVIDENDS

37.1 | The Company may by ordinary resolution declare dividends, and the directors may decide to pay interim dividends.

37.2 | A dividend must not be declared unless the directors have made a recommendation as to its amount. Such a dividend must not exceed the amount recommended by the directors.

37.6 | The directors may pay at intervals any dividend payable at a fixed rate if it appears to them that the profits available for distribution justify the payment.

37.7 | If the directors act in good faith, they do not incur any liability to the holders of shares conferring preferred rights for any loss they may suffer by the lawful payment of an interim dividend on shares with deferred or non-preferred rights.

| (c) | sending a cheque made payable to such person by post to such person at such address as the distribution recipient has specified either in writing or as the directors may otherwise decide; or

F-xi

| (d) | any other means of payment as the directors agree with the distribution recipient either in writing or by such other means as the directors decide.

38.2 | In the Articles, the “distribution recipient” means, in respect of a share in respect of which a dividend or other sum is payable:

| (a) | the holder of the share;

| (b) | if the share has two or more joint holders, whichever of them is named first in the register of members; or

| (c) | if the holder is no longer entitled to the share by reason of death or bankruptcy, or otherwise by operation of law, the transmittee.

39. | NO INTEREST ON DISTRIBUTIONS

40. | UNCLAIMED DISTRIBUTIONS

40.1 | All dividends or other sums which are:

| (a) | payable in respect of shares; and

| (b) | unclaimed after having been declared or become payable,

may be invested or otherwise made use of by the directors for the benefit of the Company until claimed.

| (b) | the distribution recipient has not claimed it,

the distribution recipient is no longer entitled to that dividend or other sum and it ceases to remain owing by the Company.

41. | NON-CASH DISTRIBUTIONS

41.1 | Subject to the terms of issue of the share in question, the Company may, by ordinary resolution on the recommendation of the directors, decide to pay all or part of a dividend or other distribution payable in respect of a share by transferring non-cash assets of equivalent value (including shares or other securities in any company).

41.2 | For the purposes of paying a non-cash distribution, the directors may make whatever arrangements they think fit, including, where any difficulty arises regarding the distribution:

| (a) | fixing the value of any assets;

| (b) | paying cash to any distribution recipient on the basis of that value in order to adjust the rights of recipients; and

| (c) | vesting any assets in trustees.

42. | WAIVER OF DISTRIBUTIONS

42.1 | Distribution recipients may waive their entitlement to a dividend or other distribution payable in respect of a share by giving the Company notice in writing to that effect, but if:

| (b) | appropriate any sum which they so decide to capitalise (“capitalised sum”) to the persons who would have been entitled to it if it were distributed by way of dividend (“persons entitled”) and in the same proportions.

43.2 | Capitalised sums must be applied:

| (a) | on behalf of the persons entitled; and

| (b) | in the same proportions as a dividend would have been distributed to them.

43.3 | Any capitalised sum may be applied in paying up new shares of a nominal amount equal to the capitalised sum which are then allotted credited as fully paid to the persons entitled or as they may direct.

43.4 | A capitalised sum which was appropriated from profits available for distribution may be applied in paying up new debentures of the Company which are then allotted credited as fully paid to the persons entitled or as they may direct.

| (b) | containing the same information which such notice is required to contain.

F-xiv

48.6 | No business may be transacted at an adjourned general meeting which could not properly have been transacted at the meeting if the adjournment had not taken place.

50. | ERRORS AND DISPUTES

51. | POLL VOTES

51.1 | A poll on a resolution may be demanded:

| (a) | in advance of the general meeting where it is to be put to the vote; or

F-xv

and a proxy notice which is not delivered in such manner shall be invalid unless the directors in their absolute discretion at any time before the start of the meeting otherwise determine.

52.2 | The Company may require proxy notices to be delivered in a particular form, and may specify different forms for different purposes.

52.3 | Proxy notices may specify how the proxy appointed under them is to vote (or that the proxy is to abstain from voting) on one or more resolutions and the proxy is obliged to vote or abstain from voting in accordance with the specified instructions. However, the Company is not obliged to check whether a proxy votes or abstains from voting as he has been instructed and shall incur no liability for failing to do so. Failure by a proxy to vote or abstain from voting as instructed at a meeting shall not invalidate proceedings at that meeting.

52.4 | Unless a proxy notice indicates otherwise, it must be treated as:

| (a) | allowing the person appointed under it as a proxy discretion as to how to vote on any ancillary or procedural resolutions put to the meeting; and

| (b) | appointing that person as a proxy in relation to any adjournment of the general meeting to which it relates as well as the meeting itself.

53. | DELIVERY OF PROXY NOTICES

53.1 | A person who is entitled to attend, speak or vote (either on a show of hands or on a poll) at a general meeting remains so entitled in respect of that meeting or any adjournment of it, even though a valid proxy notice has been delivered to the Company by or on behalf of that person.

| (b) | the proposed amendment does not, in the reasonable opinion of the chairman of the meeting, materially alter the scope of the resolution.

54.2 | A special resolution to be proposed at a general meeting may be amended by ordinary resolution, if:

| (a) | the chairman of the meeting proposes the amendment at the general meeting at which the resolution is to be proposed; and

| (b) | the amendment does not go beyond what is necessary to correct a grammatical or other non-substantive error in the resolution.

54.3 | If the chairman of the meeting, acting in good faith, wrongly decides that an amendment to a resolution is out of order, the chairman’s error does not invalidate the vote on that resolution.

4 | Note to draft: References to Topco entity and other cross-references to terms used in the Scheme to be confirmed.

F-xviii

61.2 | Notwithstanding any other provisions in these Articles or the terms of any resolution, whether ordinary or special, passed by the Company in general meeting, if the Company issues any shares other than to any member of the [Topco Group] or its nominee(s) on or after the date of the adoption of this Article and prior to the [Scheme Record Time] such shares shall be issued subject to the terms of the Scheme (and shall be [Scheme Shares] for the purposes thereof) and the original or any subsequent holder or holders of such shares shall be bound by the Scheme accordingly.

61.3 | Notwithstanding any other provision of these Articles, if any shares are issued to, or transferred or held by, any person or his nominee other than [Topco] or its nominee(s) (a “New Member”) at or after the [Scheme Record Time], such shares (the “Post-Scheme Shares”) will, provided that the Scheme has become effective, such shares shall be issued or transferred on terms that they shall, on the Effective Date (as defined in the Scheme) or, if later, on issue or transfer, be immediately transferred to [Topco] or its nominee(s) (which shall be obliged to acquire all of those Post-Scheme Shares) in consideration for and conditional on, the allotment and issue or transfer to the New Member of such number of Topco] Shares (“Consideration Shares”) and the payment of a cash amount (and the payment in cash in respect of fractional entitlements, as described in Article [61.5]) (together the “Relevant Consideration”) as that New Member would have been entitled to for those Post-Scheme Shares had they been [Scheme Shares] under the Scheme, provided that if, in respect of any New Member who is resident, located or has a registered address in a jurisdiction outside the United Kingdom or the United States or whom Topco reasonably believes to be a citizen, resident or national of a jurisdiction outside the United Kingdom or the United States, Topco is advised that the law of a country outside the United Kingdom and the United States: (i) precludes the allotment, issue and/or delivery to that New Member of Consideration Shares; or (ii) precludes the matters referred to in (i) except after compliance by the Company or Topco (as the case may be) with any governmental or other consent or any registration, filing or other formality with which the Company and/or Topco is unable to comply or compliance with which the Company and/or Topco (as the case may be) regards as unduly onerous, then Topco may, in its sole discretion, either: (A) determine that such Consideration Shares shall not be allotted, issued and delivered to such New Member, but shall instead be allotted, issued and delivered to a person appointed by Topco for such New Member on terms that such person shall, as soon as practicable following the allotment and issue of such Consideration Shares, sell the Consideration Shares so issued; or (B) determine that such Consideration Shares shall not be allotted, issued and delivered to such New Member, but instead a cash amount equal to the value of the Consideration Shares shall be paid to the New Member as soon as practicable[, save that any fractional cash entitlements shall be rounded down to the nearest penny]. In the event that the Consideration Shares are to be sold pursuant to (A), the Company shall appoint a person to act, and who shall be authorised, as attorney or agent for the New Member pursuant to this article and such person shall be authorised on behalf of such New Member to execute and deliver as transferor a form of transfer or other instrument or instruction of transfer on behalf of the New Member and to give such instructions and to do all other things which he or she may consider necessary or expedient in connection with such sale. The net proceeds of such sale (after deduction of all expenses and commissions incurred in connection with the sale) shall be paid to the persons entitled thereto in due proportion as soon as practicable following such sale, save that any fractional cash entitlements shall be rounded down to the nearest penny.

61.4 | The Consideration Shares allotted and issued or transferred to a New Member pursuant to Article 61.3 shall be credited as fully paid and shall rank pari passu in all respects with the Topco Shares in issue at that time (other than as regards any dividends or other distributions payable by reference to a record date preceding the date of allotment or transfer). The allotment, issue or transfer of the Consideration Shares shall constitute a complete discharge to [Topco] (or its nominee (as applicable) and Company in respect of their obligations.

61.5 | On any reorganisation of, or material alteration to, the share capital of the Company (including, without limitation, any subdivision and/or consolidation), the Relevant Consideration shall be adjusted by the directors in such manner as the auditors of the Company or an independent investment bank selected by the Company (whichever in their absolute discretion the directors may elect) may determine to be fair and reasonable to the New Member reflecting such reorganisation or alteration. References in this Article to Consideration Shares shall, following such adjustment, be construed accordingly.

61.6 | No fraction of a Consideration Share shall be allotted, issued or transferred to any New Member pursuant to this Article. [Any fraction of a Consideration Share to which a New Member would otherwise have become entitled shall be aggregated with the fractional entitlements of any other New Members whose shares are being transferred under this article on the same date and the maximum number of Consideration Shares resulting therefrom (rounded [down] to the nearest whole number of Consideration Shares) shall be allotted and issued to a person appointed by Topco to hold such Consideration Shares on behalf of the relevant holders of Scheme Share. Topco shall procure that such Consideration Shares are sold in the market as soon as practicable after the Combination becomes Effective or, if later,

F-xix

| their allotment and issue, and the net proceeds of sale (after deduction of all expenses and commissions incurred in connection with the sale) shall be distributed in due proportions to the persons entitled thereto (rounded down to the nearest penny).].

61.7 | To give effect to any transfer of Post-Scheme Shares required by this Article, the Company may hereby appoint any person as appointee or agent of the New Member to execute and deliver a form of transfer on behalf of the New Member in favour of [Topco] (or, if applicable, its nominee(s)) and to do all such things and execute and deliver such documents as may, in the opinion of the appointee or agent, be necessary or desirable to vest such Post-Scheme Shares in [Topco] (or its nominee(s), if applicable) including without limitation giving good receipt for the consideration for the Post-Scheme Shares. Pending the registration of [Topco] (or its nominee(s), if applicable) as the holder of any Post-Scheme Shares to be transferred pursuant to this Article, each New Member hereby irrevocably appoints [Topco] as its appointee and/or agent and/or otherwise to exercise on its behalf (in place of and to the exclusion of the relevant New Member) any voting rights attached to the Post-Scheme Shares and any or all rights and privileges attaching to the Post-Scheme Shares, to sign any consent to short notice of any general or separate class meeting of the Company and on the New Member’s behalf to execute a form of proxy in respect of its Post-Scheme Shares appointing any person nominated by [Topco] (or its nominee(s), if applicable) to attend general and separate class meetings of the Company and authorises the Company to send to [Topco] and/or its nominee(s) any notice, circular, warrant or other document or communication which may be required to be sent to them as a member of the Company, such that from the [Effective Date] (as defined in the Scheme), no New Member shall be entitled to exercise any voting rights attached to the Post-Scheme Shares or any other rights or privileges attaching to the Post-Scheme Shares. The Company shall not be obliged to issue a certificate to the New Member for any Post-Scheme Shares.

61.8 | Notwithstanding any other provision of these Articles, neither the Company nor the directors shall register the transfer of any Scheme Shares effected between the [Scheme Record Time] and the date on which the Scheme becomes effective, other than to [Topco] or its nominee(s) pursuant to the Scheme.

61.9 | If the Scheme shall not have become effective by the applicable date referred to in (or otherwise set in accordance with) clause [●] of the Scheme, this Article 61 shall cease to be of any effect.

Annex G

QUIDEL CORPORATION

Amended and Restated 2018 Equity Incentive Plan

(Amended and Restated Effective: [●], 2022)

ARTICLE I

ESTABLISHMENT; PURPOSE OF PLAN

Quidel Corporation, a Delaware corporation (the “Company”), hereby establishes the Quidel Corporation 2018 Equity Incentive Plan (the “Plan”). Upon its original approval by stockholders on May 15, 2018, the Plan superseded and replaced the Quidel Corporation 2016 Equity Incentive Plan (the “2016 Plan”) and all Prior Plans. No future awards may be made pursuant to the 2016 Plan and any other Prior Plan; provided, that, the 2016 Plan and all other Prior Plans shall remain in effect until all awards granted under the 2016 Plan and the Prior Plans have been exercised, forfeited, or cancelled or have otherwise expired or terminated.

The Plan is intended to promote the interests of the Company and its stockholders by using investment interests in the Company to attract, retain and motivate its management and other persons, to encourage and reward their contributions to the performance of the Company, and to align their interests with the interests of the Company’s stockholders. Capitalized terms not otherwise defined herein have the meanings ascribed to them in Article IX.

ARTICLE II H

EFFECTIVE DATE AND TERM OF PLAN

2.1 Term of Plan. This Plan became effective on the Effective Date and will continue in effect until the earlier of: (a) the Expiration Date; or (b) the date of any Plan termination pursuant to the provisions of Section 4.4 or Section 8.1. This amendment and restatement of the Plan will become effective upon approval by the Company’s stockholders.

2.2 Effect on Awards. Awards may be granted only during the Plan Term, but each Award properly granted during the Plan Term will remain in effect after the Expiration Date until such Award has been exercised, terminated or expired in accordance with its terms and the terms of this Plan.

ARTICLE III

SHARES SUBJECT TO PLAN

3.1 Number of Shares. The maximum number of shares of Common Stock that may be issued pursuant to Awards under this Plan is 3,150,000, plus (a) any shares of Common Stock that were authorized for issuance under the Prior Plans that, as of the Effective Date, remain available for issuance under the Prior Plans (not including any shares that are subject to, as of the Effective Date, outstanding awards under the Prior Plans or any shares that prior to the Effective Date were issued pursuant to awards granted under the Prior Plans) and (b) any shares of Common Stock subject to outstanding awards under the Prior Plans as of the Effective Date (the “Prior Plan Awards”) that on or after such date cease for any reason to be subject to such awards (other than by reason of exercise or settlement of the awards to the extent they are exercised for or settled in vested and nonforfeitable shares). The aggregate number of shares of Common Stock available for grant under this Plan and the number of shares subject to outstanding Awards shall be subject to adjustment as set forth in Section 3.4.

3.2 Source of Shares. The Common Stock to be issued under this Plan will be made available, at the discretion of the Administrator, either from authorized but unissued shares of Common Stock or from previously issued shares of Common Stock reacquired by the Company, including without limitation shares purchased on the open market.

G-1

3.3 Share Counting. The following rules shall apply solely for purposes of determining the number of shares of Common Stock available for grant at any given time:

(a) Fungible Design. Any shares of Common Stock issued pursuant to Stock Options or SARs under this Plan shall be counted against the limit set forth in Section 3.1 on a one-for-one basis and any shares of Common Stock issued pursuant to Awards under this Plan other than Stock Options or SARs shall be counted against the limit set forth in Section 3.1 as 1.5 shares for every one share of Common Stock issued pursuant to such Award Any shares of Common Stock that again become available for issuance pursuant to this Section 3.3 shall be added back as one share if such shares were subject to Stock Options or SARs (or subject to stock options or stock appreciation rights granted under the Prior Plans), and as 1.5 shares if such shares were subject to Awards other than Stock Options or SARs (or subject to awards other than stock options or stock appreciation rights granted under the Prior Plans).

(b) Terminated Awards. In the event any Award granted under the Plan (or any Prior Plan Award), is terminated, expired, forfeited, or cancelled for any reason, the number of shares of Common Stock subject to such Award (or Prior Plan Award) will again be available for grant under the Plan (i.e., any prior charge against the limit set forth in Section 3.1 shall be reversed).

(c) Cash Settled Awards. If shares of Common Stock are not delivered in connection with an Award (or Prior Plan Award) because the Award (or Prior Plan Award) may only be settled in cash rather than in Common Stock, no shares of Common Stock shall be counted against the limit set forth in Section 3.1. If any Award (or Prior Plan Award) may be settled in cash or Common Stock, the rules set forth in Section 3.3(a) shall apply until the Award (or Prior Plan Award) is settled, at which time the underlying shares of Common Stock will be added back to the shares available for grant pursuant to Section 3.1 but only if the Award (or Prior Plan Award) is settled in cash.

(d) No Liberal Share Counting for Options or SARs. The exercise of a Common Stock-settled SAR or broker-assisted “cashless” exercise of a Stock Option (or a portion thereof) will reduce the number of shares available for grant under Section 3.1 by the entire number of shares of Common Stock subject to that SAR or Stock Option (or applicable portion thereof). Shares of Common Stock tendered to pay the exercise price of a Stock Option or SAR or tendered, withheld or otherwise relinquished by a Recipient to satisfy a tax withholding obligation arising in connection with a Stock Option or SAR Award (or Prior Plan option or stock appreciation rights awards) will not again become Common Stock available for grant under the Plan. Moreover, shares of Common Stock purchased on the open market with cash proceeds generated by the exercise of a Stock Option will not increase or replenish the number of shares available for grant under Section 3.1.

If the provisions of this Section 3.3 are inconsistent with the requirements of any regulations issued pursuant to Section 422 of the IRC, the provisions of such regulations shall control over the provisions of this Section 3.3, but only as this Section 3.3 relates to Incentive Stock Options. The Administrator may adopt such other reasonable rules and procedures as it deems to be appropriate for determining the number of shares of Stock that are available for grant under Section 3.1.

3.4 Adjustment Provisions.

(a) Adjustments. If the Company consummates any Reorganization in which holders of shares of Common Stock are entitled to receive in respect of such shares any additional shares or new or different shares or securities, cash or other consideration (including, without limitation, a different number of shares of Common Stock), or if the outstanding shares of Common Stock are increased, decreased, changed or exchanged for a different number or kind of shares or other securities through merger, consolidation, sale or exchange of assets of the Company, reorganization, recapitalization, reclassification, combination, stock dividend, extraordinary cash dividend, stock split, reverse stock split, spin-off, or similar transaction then, subject to Section 8.1, an appropriate and proportionate adjustment shall be made by the Administrator in: (i) the maximum number and

G-2

kind of shares subject to this Plan as provided in Section 3.1; (ii) the number and kind of shares or other securities subject to then outstanding Awards; (iii) the price for each share or other unit of any other securities subject to, or measurement criteria applicable to, then outstanding Awards; and (iv) the number and kind of shares or other securities to be issued as Non-Employee Director Options.

(b) No Fractional Interests. No fractional interests will be issued under the Plan resulting from any adjustments.

(c) Adjustments Related to Company Stock. To the extent any adjustments relate to stock or securities of the Company, such adjustments will be made by the Administrator, whose determination in that respect will be final, binding and conclusive.

(d) Right to Make Adjustment. The grant of an Award will not affect in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes of its capital or business structure or to merge or to consolidate or to dissolve, liquidate or sell, or transfer all or any part of its business or assets.

(e) Limitations. No adjustment to the terms of an Incentive Stock Option may be made unless such adjustment either: (i) would not cause the Stock Option to lose its status as an Incentive Stock Option; or (ii) is agreed to in writing by the Administrator and the Recipient. Any action taken pursuant to this Section 3.4 shall be taken in a manner consistent with the requirements of Section 409A of the IRC.

3.5 Reservation of Shares. The Company will at all times reserve and keep available shares of Common Stock equaling at least the total number of shares of Common Stock issuable pursuant to all outstanding Awards.

ARTICLE IV

ADMINISTRATION OF PLAN

4.1 Administrator

(a) Plan Administration. Subject to the provisions of Section 4.1(b), this Plan will be administered by the Board and may also be administered by a Committee of the Board appointed pursuant to Section 4.1(b).

Unless otherwise determined by the Board, the Committee shall consist of no less than two (2) directors, each of whom qualify as: (i) a Non-Employee Director; and (ii) an “independent director” for purposes of the NASDAQ Stock Market Listing Rules (or the rules of any exchange on which the Common Stock is then listed). The Board may from time to time increase or decrease (but not below two (2)) the number of members of the Committee, remove from membership on the Committee all or any portion of its members, and/or appoint such person or persons as it desires to fill any vacancy existing on the Committee, whether caused by removal, resignation or otherwise. Unless otherwise required by this Section 4.1(b), the Board may disband the Committee at any time and, in such case, the Board will be responsible for the administration of the Plan.

4.2 Authority of Administrator.

(a) Authority to Interpret Plan. Subject to the express provisions of this Plan, the Administrator will have the power to implement, interpret and construe this Plan and any Awards and Award Documents or other documents defining the rights and obligations of the Company and Recipients hereunder and thereunder, to determine all questions arising hereunder and thereunder, and to adopt and amend such rules and regulations for the administration hereof and thereof as it may deem desirable. The interpretation and construction by the

G-3

Administrator of any provisions of this Plan or of any Award or Award Document, and any action taken by, or inaction of, the Administrator relating to this Plan or any Award or Award Document, will be within the discretion of the Administrator and will be conclusive and binding upon all persons. Subject only to compliance with the express provisions hereof, the Administrator may act in its discretion in matters related to this Plan and any and all Awards and Award Documents.

(b) Authority to Grant Awards. Subject to the express provisions of this Plan, the Administrator may from time to time in its discretion select the Eligible Persons to whom, and the time or times at which, Awards will be granted or sold, the nature of each Award, the number of shares of Common Stock or the number of rights that make up or underlie each Award, the exercise price and period (if applicable) for the exercise of each Award, and such other terms and conditions applicable to each individual Award as the Administrator may determine. Any and all terms and conditions of Awards may be established by the Administrator without regard to existing Awards or other grants and without incurring any obligation of the Company in respect of subsequent Awards. The Administrator may grant at any time new Awards to an Eligible Person who has previously received Awards or other grants (including other stock options) regardless of the status of such other Awards or grants. The Administrator may grant Awards singly or in combination or in tandem with other Awards as it determines in its discretion.

(c) Procedures. Subject to the Company’s charters (including its Compensation Administrator Charter) or bylaws or any Board resolution conferring authority on the Committee, any action of the Administrator with respect to the administration of this Plan must be taken pursuant to a majority vote of the authorized number of members of the Administrator or by the unanimous written consent of its members; provided, however, that: (i) if the Administrator is the Committee and consists of two (2) members, then actions of the Administrator must be unanimous; and (ii) actions taken by the Board will be valid if approved in accordance with applicable law.

4.3 No Liability. No member of the Board or the Committee or any designee thereof will be liable for any action or inaction with respect to this Plan or any Award or any transaction arising under this Plan or any Award except in circumstances constituting bad faith of such member.

4.4 Amendments.

(a) Plan Amendments. The Administrator may at any time and from time to time in its discretion, insofar as permitted by applicable law, rule or regulation and subject to Section 4.4(c), suspend or discontinue this Plan or revise or amend it in any respect whatsoever, and this Plan as so revised or amended will govern all Awards, including those granted before such revision or amendment. Without limiting the generality of the foregoing, the Administrator is authorized to amend this Plan to comply with or take advantage of amendments to applicable laws, rules or regulations, including the Securities Act, the Exchange Act, the IRC, or the rules of any exchange or market system upon which the Common Stock is listed or trades, or any rules or regulations promulgated thereunder. No stockholder approval of any amendment or revision will be required unless such approval is required by applicable law, rule or regulation.

(b) Award Amendments; No Repricing. The Administrator may at any time and from time to time in its discretion, but subject to Section 4.4(c) and compliance with applicable statutory or administrative requirements, accelerate or extend the vesting or exercise period of any Award as a whole or in part, and make such other modifications in the terms and conditions of an Award as it deems advisable, provided, however, that the Administrator, other than in connection with an adjustment under Section 3.4, may reduce the exercise or base price of a Stock Option or SAR (either by cancellation of such Stock Option or SAR in exchange for cash, other Awards, or a new Stock Option or SAR at such reduced exercise or base price or by amending the terms of the Stock Option or SAR to reflect such a reduced exercise or base price) only with stockholder approval.

(c) Limitation. Except as otherwise provided in this Plan or in the applicable Award Document, no amendment, revision, suspension or termination of this Plan or an outstanding Award that would cause an

G-4

Incentive Stock Option to cease to qualify as such or that would alter, impair or diminish in any material respect any rights or obligations under any Award theretofore granted under this Plan may be effected without the written consent of the Recipient to whom such Award was granted.

4.5 Other Compensation Plans. The adoption of this Plan will not affect any other stock option, incentive or other compensation plans in effect from time to time for the Company, and this Plan will not preclude the Company from establishing any other forms of incentive or other compensation for employees, directors, advisors or consultants of the Company, whether or not approved by stockholders.

4.7 References to Successor Statutes, Regulations and Rules. Any reference in this Plan to a particular statute, regulation or rule will also refer to any successor provision of such statute, regulation or rule.

4.8 Invalid Provisions. In the event that any provision of this Plan is found to be invalid or otherwise unenforceable under any applicable law, such invalidity or unenforceability is not to be construed as rendering any other provisions contained herein invalid or unenforceable, and all such other provisions are to be given full force and effect to the same extent as though the invalid and unenforceable provision were not contained herein.

4.9 Governing Law. This Plan will be governed by and interpreted in accordance with the internal laws of the State of Delaware, without giving effect to the principles of the conflicts of laws thereof.

4.10 Interpretation. Headings herein are for convenience of reference only, do not constitute a part of this Plan, and will not affect the meaning or interpretation of this Plan.

ARTICLE V

GENERAL AWARD PROVISIONS

5.1 Participation in Plan.

(a) Eligibility to Receive Awards. A person is eligible to receive grants of Awards if, at the time of the grant of the Award, such person is an Eligible Person or has received an offer of employment from the Company; provided, however, that only Non-Employee Directors are eligible to receive Non-Employee Director Options, and provided further, that Awards granted to a person who has received an offer of employment will terminate and be forfeited without consideration if the employment offer is not accepted within such time as may be specified by the Company. Status as an Eligible Person will not be construed as a commitment that any Award will be granted under this Plan to an Eligible Person or to Eligible Persons generally.

(b) Eligibility to Receive Incentive Stock Options. Incentive Stock Options may be granted only to Eligible Persons meeting the employment requirements of Section 422 of the IRC.

(c) Awards to Foreign Nationals. Notwithstanding anything to the contrary herein, the Administrator may, in order to fulfill the purposes of this Plan, modify grants of Awards to Recipients who are foreign nationals or employed outside of the United States to recognize differences in applicable law, tax policy or local custom.

5.2 Award Documents. Each Award must be evidenced by an Award Document setting forth such terms and conditions applicable to the Award as the Administrator may in its discretion determine. Awards will not be deemed made or binding upon the Company, and Recipients will have no rights thereto, until an Award

G-5

Document agreement is entered into between the Company and the Recipient or delivered by the Company to the Recipient, but an Award may have an effective date prior to the date of such an Award Document, to the extent consistent with applicable law. Award Documents may be (but need not be) identical and must comply with and be subject to the terms and conditions of this Plan, a copy of which will be provided to each Recipient and incorporated by reference into each Award Document. Any Award Document may contain such other terms, provisions and conditions not inconsistent with this Plan as may be determined by the Administrator. In case of any conflict between this Plan and any Award Document, this Plan shall control.

5.3 Payment For Awards.

(a) Payment of Exercise Price. The exercise price or other payment for an Award is payable upon the exercise of a Stock Option or upon other purchase of shares pursuant to an Award granted hereunder by delivery of cash or certified check or payment of such other consideration as the Administrator may from time to time deem acceptable in any particular instance; provided, however, that the Administrator may, in the exercise of its discretion, allow exercise of an Award in a broker-assisted or similar transaction in which the exercise price is not received by the Company until promptly after exercise.

(b) Cashless Exercise. If permitted in any case by the Administrator in its discretion, the exercise price for Awards may be paid by capital stock of the Company delivered in transfer to the Company by or on behalf of the person exercising the Award and duly endorsed in blank or accompanied by stock powers duly endorsed in blank, with signatures guaranteed in accordance with the Exchange Act if required by the Administrator; or retained by the Company from the stock otherwise issuable upon exercise or surrender of vested and/or exercisable Awards or other equity awards previously granted to the Recipient and being exercised (if applicable) (in either case valued at Fair Market Value as of the exercise date); or such other consideration as the Administrator may from time to time in the exercise of its discretion deem acceptable in any particular instance.

(c) No Precedent. Recipients will have no rights to the exercise techniques described in Section 5.3(b), and the Company may offer or permit such techniques on an ad hoc basis to any Recipient without incurring any obligation to offer or permit such techniques on other occasions or to other Recipients.

5.4 No Employment Rights. Nothing contained in this Plan (or in Award Documents or in any other documents related to this Plan or to Awards) will confer upon any Eligible Person or Recipient any right to continue in the employ of or engagement by the Company or any Affiliated Entity or constitute any contract or agreement of employment or engagement, or interfere in any way with the right of the Company or any Affiliated Entity to reduce such person’s compensation or other benefits or to terminate the employment or engagement of such Eligible Person or Recipient, with or without cause. Except as expressly provided in this Plan or in any statement evidencing the grant of an Award, the Company has the right to deal with each Recipient in the same manner as if this Plan and any such statement evidencing the grant of an Award did not exist, including, without limitation, with respect to all matters related to the hiring, discharge, compensation and conditions of the employment or engagement of the Recipient. Unless otherwise set forth in a written agreement binding upon the Company or an Affiliated Entity, all employees of the Company or an Affiliated Entity are “at will” employees whose employment may be terminated by the Company or the Affiliated Entity at any time for any reason or no reason, without payment or penalty of any kind. Any question(s) as to whether and when there has been a termination of a Recipient’s employment or engagement, the reason (if any) for such termination, and/or the consequences thereof under the terms of this Plan or any statement evidencing the grant of an Award pursuant to this Plan will be determined by the Administrator and the Administrator’s determination thereof will be final and binding.

5.5 Restrictions Under Applicable Laws and Regulations.

(a) Government Approvals. All Awards will be subject to the requirement that, if at any time the Company determines, in its discretion, that the listing, registration or qualification of the securities subject to Awards

G-6

granted under this Plan upon any securities exchange or interdealer quotation system or under any federal, state or foreign law, or the consent or approval of any government or regulatory body, is necessary or desirable as a condition of, or in connection with, the granting of such an Award or the issuance, if any, or purchase of shares in connection therewith, such Award may not be exercised as a whole or in part unless and until such listing, registration, qualification, consent or approval has been effected or obtained free of any conditions not acceptable to the Company. During the Plan Term, the Company will use its reasonable efforts to seek to obtain from the appropriate governmental and regulatory agencies any requisite qualifications, consents, approvals or authorizations in order to issue and sell such number of shares of its Common Stock as is sufficient to satisfy the requirements of this Plan. The inability of the Company to obtain any such qualifications, consents, approvals or authorizations after such reasonable efforts will relieve the Company of any liability in respect of the nonissuance or sale of such stock as to which such qualifications, consents, approvals or authorizations pertain.

(b) No Registration Obligation; Recipient Representations. The Company will be under no obligation to register or qualify the issuance of Awards or underlying securities under the Securities Act or applicable state securities laws. Unless the issuance of Awards and underlying securities have been registered under the Securities Act and qualified or registered under applicable state securities laws, the Company shall be under no obligation to issue any Awards or underlying securities unless the Awards and underlying securities may be issued pursuant to applicable exemptions from such registration or qualification requirements. In connection with any such exempt issuance, the Administrator may require the Recipient to provide a written representation and undertaking to the Company, satisfactory in form and scope to the Company, that such Recipient is acquiring such Awards and underlying securities for such Recipient’s own account as an investment and not with a view to, or for sale in connection with, the distribution of any such securities, and that such person will make no transfer of the same except in compliance with any rules and regulations in force at the time of such transfer under the Securities Act and other applicable law, and that if securities are issued without registration, a legend to this effect (together with any other legends deemed appropriate by the Administrator) may be endorsed upon the securities so issued, and to the effect of any additional representations that are appropriate in light of applicable securities laws and rules. The Company may also order its transfer agent to stop transfers of such shares. The Administrator may also require the Recipient to provide the Company such information and other documents as the Administrator may request in order to satisfy the Administrator as to the investment sophistication and experience of the Recipient and as to any other conditions for compliance with any such exemptions from registration or qualification.

5.6 Additional Conditions. Any Award may be subject to such provisions (whether or not applicable to any other Award or Recipient) as the Administrator deems appropriate, including without limitation provisions for the forfeiture of or restrictions on resale or other disposition of securities of the Company acquired under this Plan, provisions giving the Company the right to repurchase securities of the Company acquired under this Plan in the event the Recipient leaves the Company for any reason or elects to effect any disposition thereof, and provisions to comply with federal and state securities laws.

5.7 No Privileges Regarding Stock Ownership or Specific Assets. Except as otherwise set forth herein, a Recipient or a permitted transferee of an Award will have no rights as a stockholder with respect to any shares issuable or issued in connection with the Award until the Recipient has delivered to the Company all amounts payable and performed all obligations required to be performed in connection with exercise of the Award and the Company has issued such shares. No person will have any right, title or interest in any fund or in any specific asset (including shares of capital stock) of the Company by reason of any Award granted hereunder. Neither this Plan (or any documents related hereto) nor any action taken pursuant hereto is to be construed to create a trust of any kind or a fiduciary relationship between the Company and any person. To the extent that any person acquires a right to receive an Award hereunder, such right shall be no greater than the right of any unsecured general creditor of the Company.

5.8 Nonassignability. No Award is assignable or transferable except: (a) by will or by the laws of descent and distribution; or (b) subject to the final sentence of this Section 5.8, upon dissolution of marriage pursuant to a

G-7

qualified domestic relations order or, in the discretion of the Administrator on a case-by-case basis and under circumstances that would not adversely affect the interests of the Company, transfers for estate planning purposes or pursuant to a nominal transfer that does not result in a change in beneficial ownership. Subject to the final sentence of this Section 5.8, during the lifetime of a Recipient, an Award granted to such person will be exercisable only by the Recipient (or the Recipient’s permitted transferee) or such person’s guardian or legal representative. Notwithstanding the foregoing, Stock Options intended to be treated as Incentive Stock Options (or other Awards subject to transfer restrictions under the IRC) (i) may not be assigned or transferred in violation of Section 422(b)(5) of the IRC or the regulations thereunder, and nothing herein is intended to allow such assignment or transfer; and (ii) will be exercisable during a Recipient’s lifetime only by the Recipient.

5.9 Information To Recipients.

(a) Provision of Information. The Administrator in its sole discretion may determine what, if any, financial and other information is to be provided to Recipients and when such financial and other information is to be provided after giving consideration to applicable federal and state laws, rules and regulations, including, without limitation, applicable federal and state securities laws, rules and regulations.

(b) Confidentiality. The furnishing of financial and other information that is confidential to the Company is subject to the Recipient’s agreement to maintain the confidentiality of such financial and other information, and not to use the information for any purpose other than evaluating the Recipient’s position under this Plan. The Administrator may impose other restrictions on the access to and use of such confidential information and may require a Recipient to acknowledge the Recipient’s obligations under this Section 5.9(b) (which acknowledgment is not to be a condition to Recipient’s obligations under this Section 5.9(b)).

5.10 Withholding Taxes. Whenever the granting, vesting or exercise of any Award, or the issuance of any Common Stock or other securities upon exercise of any Award or transfer thereof, gives rise to tax or tax withholding liabilities or obligations, the Administrator will have the right as a condition thereto to require the Recipient to remit to the Company up to the maximum statutory amount necessary, in the applicable jurisdiction, to satisfy any federal, state, and local withholding tax requirements on any Award under the Plan. The Administrator may, in the exercise of its discretion, allow satisfaction of tax withholding requirements by accepting delivery of stock of the Company or by withholding a portion of the stock otherwise issuable in connection with an Award, in each case valued at Fair Market Value as of the date of such delivery or withholding, as the case may be.

5.11 Legends on Awards and Stock Certificates. Each Award Document and each certificate representing securities acquired upon grant, vesting or exercise of an Award must be endorsed with all legends, if any, required by applicable federal and state securities and other laws to be placed on the Award Document and/or the certificate. The determination of which legends, if any, will be placed upon Award Documents or the certificates will be made by the Administrator in its discretion and such decision will be final and binding.

5.12 Effect of Termination of Employment on Awards.

(a) Termination of Vesting. Notwithstanding anything to the contrary herein, but subject to Section 5.12(b) Awards will be exercisable by a Recipient (or the Recipient’s successor in interest) following such Recipient’s termination of employment or service only to the extent that installments thereof had become exercisable on or prior to the date of such termination.

(b) Alteration of Vesting and Exercise Periods. Notwithstanding anything to the contrary herein, the Administrator may in its discretion: (i) designate shorter or longer periods following a Recipient’s termination of employment or service during which Awards may vest or be exercised; provided, however, that any shorter periods determined by the Administrator will be effective only if provided for in this Plan or the instrument that evidences the grant to the Recipient of the affected Award or if such shorter period is agreed to in writing by the

G-8

Recipient; and (ii) accelerate the vesting of all or any portion of any Awards by increasing the number of shares purchasable at any time.

(c) Leave of Absence. In the case of any employee on an approved leave of absence, the Administrator may make such provision respecting continuance of Awards granted to such employee as the Administrator in its discretion deems appropriate, except that in no event will an Award be exercisable after the date such Award would expire in accordance with its terms had the Recipient remained continuously employed.

(d) General Cessation. Except as otherwise set forth in this Plan or an Award Document or as determined by the Administrator in its discretion, all Awards granted to a Recipient, and all of such Recipient’s rights thereunder, will terminate upon termination for any reason of such Recipient’s employment or service with the Company or any Affiliated Entity (or cessation of any other service relationship between the Recipient and the Company or any Affiliated Entity in place as of the date the Award was granted).

5.13 Lock-Up Agreements. Each Recipient agrees as a condition to receipt of an Award that, in connection with any public offering by the Company of its equity securities and upon the request of the Company and the principal underwriter (if any) in such public offering, any shares of Common Stock acquired or that may be acquired upon exercise or vesting of an Award may not be sold, offered for sale, encumbered, or otherwise disposed of or subjected to any transaction that will involve any sales or other transfer of securities of the Company, or any interest therein, without the prior written consent of the Company or such underwriter, as the case may be, for a period of not more than 365 days after the commencement date of such public offering. Each Recipient will, if requested by the Company or the principal underwriter, enter into a separate agreement to the effect of this Section 5.13.

5.14 Restrictions on Common Stock and Other Securities. Common Stock or other securities of the Company issued or issuable in connection with any Award will be subject to all of the restrictions imposed under this Plan upon Common Stock issuable or issued upon exercise of Stock Options, except as otherwise determined by the Administrator.

5.15 Limits on Awards to Eligible Persons. Notwithstanding any provision in the Plan to the contrary, the aggregate value of cash compensation and the grant date fair market value of shares of Common Stock subject to Awards (calculated as of the date of grant in accordance with applicable accounting rules) that may be awarded or granted during any single calendar year to any one Eligible Person who is a Non-Employee Director shall not exceed $750,000. For the avoidance of doubt, if a Non-Employee Director serves the Company in more than one capacity during any single calendar year, the total compensation limit described in this Section 5.15 shall only apply to the compensation paid for services performed as a Non-Employee Director. To the extent any Non-Employee Director compensation is deferred, it shall be counted toward this total compensation limit only for the year in which the compensation was first earned or granted. The limitations set forth in this Section 5.15 will be subject to adjustment as provided in Section 3.4 or under Article VIII.

5.16 Section 409A. If any payments under this Plan are subject to the provisions of Section 409A of the IRC, it is intended that the terms of this Plan and the applicable Award Document will comply fully with and meet all of the requirements of Section 409A of the IRC. If, at the time of an Eligible Person’s Separation from Service, the Company has any stock which is publicly traded on an established securities market or otherwise, and if the Eligible Person is considered to be a Specified Employee, to the extent any payment for any Award is subject to the requirements of Section 409A of the IRC and is payable upon the Eligible Person’s Separation from Service, such payment shall not commence prior to the first business day following the date which is six (6) months after the Eligible Person’s Separation from Service (or if earlier than the end of the six (6) month period, the date of the Eligible Person’s death). Any amounts that would have been distributed during such six (6) month period will be distributed on the day following the expiration of the six (6) month period. Under no circumstances may the time or schedule of any payment for any Award that is subject to the requirements of Section 409A of the IRC be

G-9

accelerated or subject to further deferral except as otherwise permitted or required pursuant to regulations and other guidance issued pursuant to Section 409A of the IRC. If the Company fails to make any payment pursuant to the payment provisions applicable to an Award that is subject to Section 409A of the IRC, either intentionally or unintentionally, within the time period specified in such provisions, but the payment is made within the same calendar year, such payment will be treated as made within the specified time period. In addition, in the event of a dispute with respect to any payment, such payment may be delayed in accordance with the regulations and other guidance issued pursuant to Section 409A of the IRC.

5.17 Clawback. Every Award issued pursuant to this Plan is subject to potential forfeiture or recovery to the fullest extent called for by law, any applicable listing standard, or any current or future clawback policy that may be adopted by the Company from time to time, including, without limitation, any clawback policy adopted to comply with the final rules issued by the Securities and Exchange Commission and the final listing standards to be adopted by the NASDAQ Stock Market (or the rules of any exchange on which the Common Stock is then listed) pursuant to Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act. By accepting an Award, each Recipient consents to the potential forfeiture or recovery of his or her Awards pursuant to applicable law, listing standard, and/or Company clawback policy, and agrees to be bound by and comply with the clawback policy and to return the full amount required by the clawback policy. As a condition to the receipt of any Award, a Recipient may be required to execute any requested additional documents consenting to and agreeing to abide by the Company clawback policy as it may be amended from time to time.

ARTICLE VI

AWARDS

6.1 Stock Options.

(a) Nature of Stock Options. Stock Options may be Incentive Stock Options or Nonqualified Stock Options.

(b) Option Exercise Price. The exercise price for each Stock Option will be determined by the Administrator as of the date such Stock Option is granted and shall not be less than the Fair Market Value of the underlying stock on the date of grant; provided, however, that in the case of Stock Options granted to employees upon a merger or acquisition, and to the extent permitted by Section 409A of the IRC, the exercise price may be higher or lower than the Fair Market Value of the underlying stock on the date of grant if such exercise price is required to assume or substitute options held by employees of the acquired corporation at the time of the acquisition.

(c) Option Period and Vesting. Stock Options granted hereunder will vest and may be exercised as determined by the Administrator, except that the exercise of Stock Options after termination of the Recipient’s employment or service shall be subject to Section 5.12 and Section 6.1(e). Each Stock Option granted hereunder and all rights or obligations thereunder shall expire on such date as may be determined by the Administrator, but not later than ten (10) years after the date the Stock Option is granted and may be subject to earlier termination as provided herein or in the Award Document. Except as otherwise provided herein, a Stock Option will become exercisable, as a whole or in part, on the date or dates specified by the Administrator and thereafter will remain exercisable until the exercise, expiration or earlier termination of the Stock Option.

(d) Exercise of Stock Options. The exercise price for Stock Options will be paid as set forth in Section 5.3. No Stock Option will be exercisable except in respect of whole shares, and fractional share interests shall be disregarded. Not fewer than 100 shares of Common Stock (or such other amount as may be set forth in the applicable Award Document) may be purchased at one time and Stock Options must be exercised in multiples of 100 unless the number purchased is the total number of shares for which the Stock Option is exercisable at the time of exercise. A Stock Option will be deemed to be exercised when the Secretary or other designated official

G-10

of the Company receives written notice of such exercise from the Recipient in such form as the Company may specify from time to time, together with payment of the exercise price in accordance with Section 5.3 and any amounts required under Section 5.10 or, with permission of the Administrator, arrangement for such payment. Notwithstanding any other provision of this Plan, the Administrator may impose, by rule and/or in Award Documents, such conditions upon the exercise of Stock Options (including, without limitation, conditions limiting the time of exercise to specified periods) as may be required to satisfy applicable regulatory requirements, including, without limitation, Rule 16b-3 and Rule 10b-5 under the Exchange Act, and any amounts required under Section 5.10, or any applicable section of or regulation under the IRC.

(e) Termination of Employment.

| (i) | Termination for Just Cause. Subject to Section 5.12 and except as otherwise provided in a written agreement between the Company or an Affiliated Entity and the Recipient, which may be entered into at any time before or after termination of employment or service, in the event of a Just Cause Dismissal of a Recipient all of the Recipient’s unexercised Stock Options, whether or not vested, will expire and become unexercisable as of the date of such Just Cause Dismissal.

| (ii) | Termination Other Than for Just Cause. Subject to Section 5.12 and except as otherwise provided in a written agreement between the Company or an Affiliated Entity and the Recipient, which may be entered into at any time before or after termination of employment or service, if a Recipient’s employment or service with the Company or any Affiliated Entity terminates for:

| (A) | any reason other than for Just Cause Dismissal, death, or Permanent Disability, the Recipient’s vested Stock Options will expire and become unexercisable as of the earlier of: (1) the date such Stock Options would expire in accordance with their terms had the Recipient remained employed; and (2) 90 days after the date of termination of employment or service.

| (B) | death or Permanent Disability, the Recipient’s unexercised, vested Stock Options will expire and become unexercisable as of the earlier of: (1) the date such Stock Options would expire in accordance with their terms had the Recipient remained employed; and (2) one year after the date of termination of employment or service.

(f) Special Provisions Regarding Incentive Stock Options. Notwithstanding anything herein to the contrary:

| (i) | The exercise price and vesting period of any Stock Option intended to be treated as an Incentive Stock Option must comply with the provisions of Section 422 of the IRC and the regulations thereunder. As of the Effective Date, such provisions require, among other matters, that: (A) the exercise price must not be less than the Fair Market Value of the underlying stock as of the date the Incentive Stock Option is granted, and not less than 110% of the Fair Market Value as of such date in the case of a grant to a Significant Stockholder; and (B) that the Incentive Stock Option not be exercisable after the expiration of ten (10) years from the date of grant or the expiration of five (5) years from the date of grant in the case of an Incentive Stock Option granted to a Significant Stockholder.

| (ii) | The aggregate Fair Market Value (determined as of the respective date or dates of grant) of the Common Stock for which one or more Stock Options granted to any Recipient under this Plan (or any other option plan of the Company or of any Parent Corporation or Subsidiary Corporation) may for the first time become exercisable as Incentive Stock Options under the federal tax laws during any one calendar year may not exceed $100,000.

| (iii) | Any Stock Options granted as Incentive Stock Options pursuant to this Plan that for any reason fail or cease to qualify as such will be treated as Nonqualified Stock Options. If the limit described in Section 6.1(f)(ii) is exceeded, the earliest granted Stock Options will be treated as Incentive Stock Options, up to such limit.

G-11

| (iv) | Subject to adjustment as provided in Section 3.4, the maximum number of shares of Common Stock that may be issued as Incentive Stock Options under the Plan shall be the same numeric limit set forth in Section 3.1.

(g) Non-Employee Director Options. Article VII will govern Non-Employee Director Options to the extent inconsistent with this Section 6.1.

6.2 Performance Awards.

(a) Grant of Performance Award. The Administrator will determine in its discretion the performance goals (which need not be identical and may be established on an individual or group basis) governing Performance Awards, the terms thereof, and the form and time of payment of Performance Awards.

(b) Payment of Award. Upon satisfaction of the conditions applicable to a Performance Award, payment will be made to the Recipient in cash, in shares of Common Stock valued at Fair Market Value as of the date payment is due, or in a combination of Common Stock and cash, as the Administrator in its discretion may determine.

6.3 Restricted Stock.

(a) Award of Restricted Stock. The Administrator will determine the Purchase Price (if any), the terms of payment of the Purchase Price, the restrictions upon the Restricted Stock, and when such restrictions will lapse.

(b) Requirements of Restricted Stock. All shares of Restricted Stock granted or sold pursuant to this Plan will be subject to the following conditions:

| (i) | No Transfer. The shares may not be sold, assigned, transferred, pledged, hypothecated or otherwise disposed of, alienated or encumbered until the restrictions are removed or expire.

| (ii) | Certificates. The Administrator may require that the certificates representing Restricted Stock granted or sold to a Recipient remain in the physical custody of an escrow holder or the Company until all restrictions are removed or expire.

| (iii) | Restrictive Legends. Each certificate representing Restricted Stock granted or sold to a Recipient pursuant to this Plan will bear such legend or legends making reference to the restrictions imposed upon such Restricted Stock as the Administrator in its discretion deems necessary or appropriate to enforce such restrictions.

| (iv) | Other Restrictions. The Administrator may impose such other conditions on Restricted Stock as the Administrator may deem advisable, including, without limitation, restrictions under the Securities Act, under the Exchange Act, under the requirements of any stock exchange or interdealer quotation system upon which such Restricted Stock or other securities of the Company are then listed or traded and under any blue sky or other securities laws applicable to such shares.

(c) Lapse of Restrictions. The restrictions imposed upon Restricted Stock will lapse in accordance with such terms or other conditions as are determined by the Administrator.

(d) Rights of Recipient. Subject to the provisions of Section 6.3(b) and any restrictions imposed upon the Restricted Stock, the Recipient will have all rights of a stockholder with respect to the Restricted Stock granted or sold to such Recipient under this Plan, including, without limitation, the right to vote the shares and receive all dividends and other distributions paid or made with respect thereto.

(e) Termination of Employment. Unless the Administrator in its discretion determines otherwise, if a Recipient’s employment or service with the Company or any Affiliated Entity terminates for any reason, all of

G-12

the Recipient’s Restricted Stock remaining subject to restrictions on the date of such termination of employment or service will be repurchased by the Company at the Purchase Price (if any) paid by the Recipient to the Company, without interest or premium, and otherwise returned to the Company without consideration.

6.4 Stock Appreciation Rights.

(a) Granting of Stock Appreciation Rights. The Administrator may at any time and from time to time approve the grant to Eligible Persons of Stock Appreciation Rights, related or unrelated to Stock Options.

(b) SARs Related to Options.

| (i) | A Stock Appreciation Right related to a Stock Option will entitle the holder of the related Stock Option, upon exercise of the Stock Appreciation Right, to surrender such Stock Option, or any portion thereof to the extent previously vested but unexercised, with respect to the number of shares as to which such Stock Appreciation Right is exercised, and to receive payment of an amount computed pursuant to Section 6.4(b)(iii). Such Stock Option will, to the extent surrendered, then cease to be exercisable.

| (ii) | A Stock Appreciation Right related to a Stock Option hereunder will be exercisable at such time or times, and only to the extent that, the related Stock Option is exercisable, and will not be transferable except to the extent that such related Stock Option may be transferable (and under the same conditions), will expire no later than the expiration of the related Stock Option, and may be exercised only when the market price of the Common Stock subject to the related Stock Option exceeds the exercise price of the Stock Option.

| (iii) | Upon the exercise of a Stock Appreciation Right related to a Stock Option, the Recipient will be entitled to receive payment of an amount determined by multiplying: (A) the difference obtained by subtracting the exercise price of a share of Common Stock specified in the related Stock Option from the Fair Market Value of a share of Common Stock on the date of exercise of such Stock Appreciation Right (or as of such other date or as of the occurrence of such event as may have been specified in the instrument evidencing the grant of the Stock Appreciation Right), by (B) the number of shares as to which such Stock Appreciation Right is exercised.

(c) SARs Unrelated to Options. The Administrator may grant Stock Appreciation Rights unrelated to Stock Options. Section 6.4(b)(iii) will govern the amount payable at exercise under such Stock Appreciation Right, except that in lieu of an option exercise price the initial base amount specified in the Award shall be used. All Stock Appreciation Rights unrelated to Stock Options shall be granted subject to the same terms and conditions applicable to Stock Options as set forth in Section 6.1.

(d) Limits. Notwithstanding the foregoing, the Administrator, in its discretion, may place a dollar limitation on the maximum amount that will be payable upon the exercise of a Stock Appreciation Right.

(e) Payments. Payment of the amount determined under the foregoing provisions may be made solely in whole shares of Common Stock valued at their Fair Market Value on the date of exercise of the Stock Appreciation Right or, alternatively, at the discretion of the Administrator, in cash or in a combination of cash and shares of Common Stock as the Administrator deems advisable. The Administrator has full discretion to determine the form in which payment of a Stock Appreciation Right will be made and to consent to or disapprove the election of a Recipient to receive cash in full or partial settlement of a Stock Appreciation Right. If the Administrator decides to make full payment in shares of Common Stock, and the amount payable results in a fractional share, payment for the fractional share will be made in cash.

6.5 Stock Payments. The Administrator may approve Stock Payments to any Eligible Person on such terms and conditions as the Administrator may determine. Stock Payments will replace cash compensation at the Fair Market Value of the Common Stock on the date payment is due.

G-13

6.6 Dividend Equivalents and Dividends. The Administrator may grant dividends and/or Dividend Equivalents to any Recipient who has received an Award denominated in shares of Common Stock other than Stock Options or SARs or, to the extent unearned, Performance Awards. Dividends and Equivalents may be paid in cash, Common Stock or other Awards, in each case, in accordance with the requirements of Section 409A or an exception thereto; the amount of Dividend Equivalents paid other than in cash will be determined by the Administrator by application of such formula as the Administrator may deem appropriate to translate the cash value of dividends paid to the alternative form of payment of the Dividend Equivalent. Dividends and Dividend Equivalents will be computed as of each dividend record date but in no event may any dividends or Dividend Equivalents vest or be paid prior to the vesting of the corresponding Award.

6.7 Stock Bonuses. The Administrator may issue Stock Bonuses to Eligible Persons on such terms and conditions as the Administrator may determine.

6.8 Stock Sales. The Administrator may sell to Eligible Persons shares of Common Stock on such terms and conditions as the Administrator may determine.

6.9 Phantom Stock. The Administrator may grant Awards of Phantom Stock to Eligible Persons. Phantom Stock is a cash payment measured by the Fair Market Value of a specified number of shares of Common Stock on a specified date, or measured by the excess of such Fair Market Value over a specified minimum, which may but need not include a Dividend Equivalent.

6.10 Restricted Stock Units. The Administrator is authorized to make Awards of Restricted Stock Units to Eligible Persons in such amounts and subject to such terms and conditions as determined by the Administrator.

(a) Voting Rights. During the restricted period, Eligible Persons holding Restricted Stock Units shall have no voting rights with respect to the Common Stock subject to such Restricted Stock Units. Voting rights will only be available after the issuance of Common Stock pursuant to the Plan.

(b) Payment for Restricted Stock Units. Payment for any vested Restricted Stock Units will generally be made in one lump sum payment of shares of Common Stock. As a general rule, with the exception of deferred compensation elections, the shares payable under any Restricted Stock Unit Award will be issued to the Eligible Person within 60 days following the date on which the Restricted Stock Units vest. Unless the related Award Document is structured to qualify for an exception to the requirements of Section 409A of the IRC, such payment is intended to be made at a specified time or pursuant to a fixed schedule under Treas. Reg. Section 1.409A-3(a)(4).

6.11 Other Stock-Based Benefits. The Administrator is authorized to grant Other Stock-Based Benefits. Other Stock-Based Benefits are any arrangements granted under this Plan not otherwise described above that: (a) by their terms might involve the issuance or sale of Common Stock or other securities of the Company; or (b) involve a benefit that is measured, as a whole or in part, by the value, appreciation, dividend yield or other features attributable to a specified number of shares of Common Stock or other securities of the Company.

ARTICLE VII

NON-EMPLOYEE DIRECTOR OPTIONS

7.1 Vesting. All grants of Non-Employee Director Options shall fully vest and become exercisable one year following the grant date if the Recipient has remained a director for the entire period from the date of grant to such vesting date. Notwithstanding the foregoing, if the Recipient has remained a director from the period of the date of grant until the next annual meeting of stockholders following the grant date, but ceases to be a director following the annual meeting of stockholders (either because the director is not re-elected or because the director chooses not to run for another term), the Stock Options that were granted to the director at the annual meeting in

G-14

the prior year shall continue to vest following the date that the Recipient ceases to be a director and shall become exercisable one year following the grant date. Except as otherwise provided in this Section 7.1, all Non-Employee Director Options that have not vested and become exercisable at the time the Recipient ceases to be a director shall terminate.

7.2 Exercise. Non-Employee Director Options will be exercisable, and the exercise price therefor shall be paid, in the same manner as provided herein for other Stock Options.

7.3 Term of Options and Effect of Termination. Notwithstanding any other provision of the Plan, no Non-Employee Director Option granted under the Plan shall be exercisable after the expiration of ten years from the effective date of its grant. In the event that the Recipient of any Non-Employee Director Options granted under the Plan shall cease to be a director of the Company, subject to Section 5.12, all grants of Non-Employee Director Options shall be exercisable, to the extent already exercisable at the date such Recipient ceases to be a director and regardless of the reason the Recipient ceases to be a director until the expiration of the Non-Employee Director Option according to its terms and shall then terminate. In the event of the death of a Recipient while such Recipient is a director of the Company or within the period after termination of such status during which he or she is permitted to exercise a Stock Option such Stock Option may be exercised by any person or persons designated by the Recipient on a beneficiary designation form adopted by the Administrator for such purpose or, if there is no effective beneficiary designation form on file with the Company, by the executors or administrators of the Recipient’s estate or by any person or persons who shall have acquired the Stock Option directly from the Recipient by his or her will or the applicable laws of descent and distribution.

7.4 Amendment; Suspension. The Administrator may at any time and from time to time in its discretion: (a) change the vesting periods associated with the Non-Employee Director Options; and (b) suspend and reactivate this Article VII.

ARTICLE VIII

CHANGE IN CONTROL

8.1 Provision for Awards Upon Change in Control. Unless otherwise set forth in an Award Document or in this Section 8.1, as of the effective time and date of any Change in Control, this Plan and any then outstanding Awards (whether or not vested) will automatically terminate unless: (a) provision is made in writing in connection with such transaction for the continuance of this Plan and for the assumption of such Awards, or for the substitution for such Awards of new awards covering the securities of a successor entity or an affiliate thereof, with appropriate adjustments as to the number and kind of securities and exercise prices or other measurement criteria, in which event this Plan and such outstanding Awards will continue or be replaced, as the case may be, in the manner and under the terms so provided; or (b) the Board otherwise provides in writing for such adjustments as it deems appropriate in the terms and conditions of the then-outstanding Awards (whether or not vested), including, without limitation, (i) accelerating the vesting of outstanding Awards; and/or (ii) providing for the cancellation of Awards and their automatic conversion into the right to receive the securities, cash or other consideration that a holder of the shares underlying such Awards would have been entitled to receive upon consummation of such Change in Control had such shares been issued and outstanding immediately prior to the effective date and time of the Change in Control (net of the appropriate option exercise prices). If, pursuant to the foregoing provisions of this Section 8.1, this Plan and the Awards terminate by reason of the occurrence of a Change in Control without provision for any of the action(s) described in clause (a) or (b) hereof, then subject to Section 5.12 and Section 6.1(e), any Recipient holding outstanding Awards will have the right, at such time prior to the consummation of the Change in Control as the Board designates, to exercise or receive the full benefit of the Recipient’s Awards to the full extent not theretofore exercised, including any installments which have not yet become vested. Notwithstanding anything to the contrary in this Section 8.1, the vesting provisions of Section 7.1 or any other provision in the Plan, all Non-Employee Director Options granted under the Plan shall automatically vest and become exercisable immediately prior to any Change in Control if the optionee is a director of the Company at that time.

1. Purpose.

It is the intention of the Company to have the Plan qualify as an “Employee Stock Purchase Plan” under Section 423 of the Internal Revenue Code of 1986, as amended.

(b) Any provisions of the Plan to the contrary notwithstanding, no Employee shall be granted an option under the Plan (i) if, immediately after the grant, such Employee (or any other person whose stock would be attributed to such Employee pursuant to Section 425(d) of the Code) would own stock and/or hold outstanding options to purchase stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or of any subsidiary of the Company, or (ii) which permits his rights to purchase stock under all employee stock purchase plans of the Company and its subsidiaries to accrue at a rate which exceeds Twenty Five Thousand Dollars ($25,000) of fair market value of such stock (determined at the time such option is granted) for each calendar year in which such option is outstanding at any time.

4. Offering Periods. The Plan shall be implemented by one offering during each six month period of the Plan, commencing on or about, and continuing thereafter until terminated in accordance with paragraph 19 hereof. The Board of

H-1

Directors of the Company shall have the power to change the duration of offering periods with respect to future offerings without stockholder approval if such change is announced at least fifteen (15) days prior to the scheduled beginning at the first offering period to be affected.

5. Participation.

(a) An eligible Employee may become a participant in the Plan by completing a subscription agreement authorizing payroll deduction on the form provided by the Company and filing it with the Company’s payroll office prior to the applicable Offering Date, unless a later time for filing the subscription agreement is set by the Board for all eligible employees with respect to a given offering.

(b) Payroll deductions for a participant shall commence on the first payroll following the Offering Date and shall end on the Exercise Date of the offering to which such authorization is applicable, unless sooner terminated by the participant as provided in paragraph 10.

6. Payroll Deductions.

(a) At the time a participant files his subscription agreement, he shall elect to have payroll deductions made on each payday during the offering period in an amount not exceeding ten percent (10%) of the Compensation which he received on the payday immediately preceding the Offering Date, and the aggregate of such payroll deductions during the offering period shall not exceed ten percent (10%) of his aggregate Compensation during said offering period.

(b) All payroll deductions made by a participant shall be credited to his account under the Plan. A participant may not make any additional payments into such account.

(c) A participant may discontinue his participation in the Plan as provided in paragraph 10, or may lower, but not increase, the rate of his payroll deductions during the offering period by completing or filing with the Company a new authorization for payroll deduction. The change in rate shall be effective fifteen (15) days following the Company’s receipt of the new authorization.

7. Grant of Option.

(a) On the Offering Date of each six month offering period, each eligible Employee participating in the Plan shall be granted an option to purchase (at the per share option price) up to a number of shares of the Company’s Common Stock determined by dividing such Employee’s payroll deductions to be accumulated during such offering period (not to exceed an amount equal to ten percent (10%) of his Compensation as of the date of the commencement of the applicable offering period) by eighty-five percent (85%) of the fair market value of a share of the Company’s Common Stock on the Offering Date, subject to the limitations set forth in Section 3(b) and 12 hereof. Fair market value of a share of the Company’s Common Stock shall be determined as provided in Section 7(b) herein. Notwithstanding the foregoing, no employee shall be granted an option to purchase more than 5,000 shares of the Company’s Common Stock during any six-month offering period.

(b) The option price per share of the shares offered in a given offering period shall be the lower of: (i) 85% of the fair market value of a share of the Common Stock of the Company on the Offering Date; or (ii) 85% of the fair market value of a share of the Common Stock of the Company on the Exercise Date. The fair market value of the Company’s Common Stock on a given date shall be the mean of the reported bid and asked prices for that date except that the fair market value on the Offering Date of the initial offering period shall be the initial public offering price.

8. Exercise of Option. Unless a participant withdraws from the Plan as provided in paragraph 10, his option for the purchase of shares will be exercised automatically on the Exercise Date of the offering period, and the maximum number of full shares subject to option will be purchased for him at the applicable option price with the accumulated payroll deductions in his account. If the total amount of payroll deductions for a participant during the offering period exceeds the purchase price of such shares as determined in Section 7(a), such excess amount will be refunded to the participant.

9. Delivery. As promptly as practicable after the Exercise Date of each offering, the Company shall arrange the delivery to each participant, as appropriate, of a certificate representing the shares purchased upon exercise of his option.

H-2

Any cash remaining to the credit of a participant’s account under the Plan after a purchase by him of shares at the termination of each offering period, or which is insufficient to purchase a full share of Common Stock of the Company, shall be returned to said participant.

10. Withdrawal; Termination of Employment.

(a) A participant may withdraw all but not less than all the payroll deductions credited to his account under the Plan up to one week prior to the Exercise Date of the offering period by giving written notice to the Company. All of the participant’s payroll deductions credited to his account will be paid to him promptly after receipt of his notice of withdrawal and his option for the current period will be automatically terminated, and no further payroll deductions for the purchase of shares will be made during the offering period.

(b) Upon termination of the participant’s employment prior to the Exercise Date of the offering period for any reason, including retirement or death, the payroll deductions credited to his account will be returned to him or, in the case of his death, to the person or persons entitled thereto under paragraph 14, and his option will be automatically terminated.

(c) in the event an Employee fails to remain in the continuous employ of the Company for at least twenty (20) hours per week during the offering period in which the employee is a participant, he will be deemed to have elected to withdraw from the Plan and the payroll deductions credited to his account will be returned to him and his option terminated.

(d) A participant’s withdrawal from an offering will not have any effect upon his eligibility to participate in a succeeding offering or in any similar plan which may hereafter be adopted by the Company.

11. Interest. No interest shall accrue on the payroll deductions of a participant in the Plan.

12. Stock.

(a) The maximum number of shares of the Company’s Common Stock that shall be made available for sale under the Plan shall be 2,250,000 shares, subject to adjustment upon changes in capitalization of the Company as provided in paragraph 18. If the total number of shares which would otherwise be subject to options granted pursuant to Section 7(a) hereof on the Offering Date of an offering period exceeds the number of shares then available under the Plan (after deduction of all shares for which options have been exercised or are then outstanding), the Company shall make a pro rata allocation of the shares remaining available for option grant in as uniform a manner as shall be practicable and as it shall determine to be equitable. In such event, the Company shall give written notice of such reduction of the number of shares subject to the option to each Employee affected thereby and shall similarly reduce the rate of payroll deductions, if necessary.

(b) The participant will have no interest or voting right in shares covered by his option until such option has been exercised.

(c) Shares to be delivered to a participant under the Plan will be registered in the name of the participant or in the name of the participant and his spouse.

13. Administration. The Plan shall be administered by the Board of Directors of the Company or a committee appointed by the Board. The administration, interpretation or application of the Plan by the Board or its committee shall be final, conclusive and binding upon all participants. Members of the Board who are eligible Employees are permitted to participate in the Plan, provided that:

(a) Members of the Board who are eligible to participate in the Plan may not vote on any matter affecting the administration of the Plan or the grant of any option pursuant to the Plan.

(b) If a committee is established to administer the Plan, no member of the Board who is eligible to participate in the Plan may be a member of the committee.

14. Designation of Beneficiary.

(a) A participant may file a written designation of a beneficiary who is to receive any shares and cash, if any, from the participant’s account under the Plan in the event of such participant’s death subsequent to the end of the offering period but

H-3

prior to delivery to him of such shares and cash. In addition, a participant may file a written designation of a beneficiary who is to receive any cash from the participant’s account under the Plan in the event of such participant’s death prior to the Exercise Date of the offering period.

(b) Such designation of beneficiary may be changed by the participant at any time by written notice. In the event of the death of a participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such participant’s death, the Company shall deliver such shares and/or cash to the executor or administrator of the estate of the participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.

15. Transferability. Neither payroll deductions credited to a participant’s account nor any rights with regard to the exercise of an option or to receive shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in paragraph 14 hereof) by the participant. Any such attempt at assignment, transfer, pledge or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw funds in accordance with paragraph 10.

16. Use of Funds. All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions.

17. Reports. Individual accounts will be maintained for each participant in the Plan. Statements of account will be given to participating Employees semi-annually promptly following the Exercise Date, which statements will set forth the amounts of payroll deductions, the per share purchase price, the number of shares purchased and the remaining cash balance, if any.

18. Adjustments Upon Changes in Capitalization. Subject to any required action by the stockholders of the Company, the number of shares of Common Stock covered by each option under the Plan which has not yet been exercised and the number of shares of Common Stock which have been authorized for issuance under the Plan but have not yet been placed under option (collectively, the “Reserves”), as well as the price per share of Common Stock covered by each option under the Plan which has not yet been exercised, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split or the payment of a stock dividend (but only on the Common Stock) or any other increase or decrease in the number of shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration”. Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issue by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an option.

The Board may, if it so determines in the exercise of its sole discretion, also make provision for adjusting the Reserves, as well as the price per share of Common Stock covered by each outstanding option, in the event that the Company effects one or more reorganizations, recapitalizations, rights offerings or other increases or reductions of shares of its outstanding Common Stock, and in the event of the Company being consolidated with or merged into any other corporation.

19. Amendment or Termination. The Board of Directors of the Company may at any time terminate or amend the Plan. No such termination can affect options previously granted, nor may an amendment make any change in any option theretofore granted which adversely affects the rights of any participant, nor may an amendment be made without prior approval of the stockholders of the Company if such amendment would:

(a) increase the number of shares that may be issued under the Plan;

(b) Permit payroll deductions at a rate in excess of ten percent (10%) of the participant’s Compensation;

(c) Modify the requirements concerning which employees (or class of employees) are eligible for participation in the Plan; or

(d) Materially increase the benefits which may accrue to participants under the Plan.

H-4

20. Notices. All notices or other communications by a participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.

21. Stockholder Approval. Continuance of the Plan shall be subject to approval by the stockholders of the Company within twelve months before or after the date the Plan is adopted.

INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. | INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Topco is incorporated under the laws of the state of Delaware. Section 145(a) of the DGCL authorizes a corporation to indemnify any person who was or is a party, or is threatened to be made a party, to a threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding, if the person acted in good faith and in a manner the person reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful.

Section 145(b) of the DGCL provides in relevant part that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

The DGCL also provides that indemnification under Sections 145(a) and (b) can only be made upon a determination that indemnification of the present or former director, officer or employee or agent is proper in the circumstances because such person has met the applicable standard of conduct set forth in Sections 145(a) and (b). Such determination shall be made, with respect to a person who is a director or officer at the time of such determination, (1) by a majority vote of directors who are not a party to the action at issue (even though less than a quorum), (2) by a majority vote of a designated committee of these directors (even though less than a quorum), (3) if there are no such directors, or these directors authorize, by the written opinion of independent legal counsel, or (4) by the stockholders.

Section 145(c) of the DGCL provides that to the extent a present or former director or officer of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Sections 145(a) or (b), or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorney’s fees) actually and reasonably incurred by such person in connection therewith. Section 145(e) of the DGCL provides that expenses (including attorneys’ fees) incurred by an officer or director of the corporation in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized in Section 145 of the DGCL.

Such expenses (including attorneys’ fees) incurred by former directors and officers or other employees and agents of the corporation or by persons serving at the request of the corporation as directors, officers, employees or agents of another corporation, partnership, joint venture, trust or other enterprise may be so paid upon such terms and conditions, if any, as the corporation deems appropriate.

Section 145(g) of the DGCL also empowers a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any

II-1

liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would have the power to indemnify such person against such liability under Section 145 of the DGCL.

Section 102(b)(7) of the DGCL permits a corporation to provide for eliminating or limiting the personal liability of one of its directors for any monetary damages related to a breach of fiduciary duty as a director, as long as the corporation does not eliminate or limit the liability of a director for (a) a breach of the director’s duty of loyalty to the corporation or its stockholders, (b) acts or omissions not in good faith or involving intentional misconduct or a knowing violation of law, (c) a violation of Section 174 of the DGCL (unlawful dividends) or (d) any transaction from which the director derived an improper personal benefit.

Article 8 of Topco’s Certificate of Incorporation eliminates the personal liability of Topco’s directors to the fullest extent permitted by the DGCL. Such section eliminates the personal liability of a director to Topco or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (a) for any breach of the director’s duty of loyalty to Topco or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) under Section 174 of the DGCL (unlawful dividends) or (d) for any transaction from which the director derived an improper personal benefit. Under the Topco Certificate of Incorporation, Topco agrees that it is the indemnitor of first resort to provide advancement of expenses or indemnification to directors and officers.

In the BCA filed as Exhibit 2.1 hereto, Topco agrees to (i) indemnify and hold harmless, and provide advancement of expenses to, all past and present (as of the Quidel Effective Time) directors, officers and employees of Quidel and its subsidiaries and Ortho and its subsidiaries (in all of their capacities) (A) to the same extent such persons are indemnified or have the right to advancement of expenses as of the date of the BCA by Quidel pursuant to the organizational documents of Quidel or its subsidiaries and indemnification agreements, if any, and by Ortho pursuant to the organizational documents of Ortho or its subsidiaries and indemnification agreements, if any, as applicable, in existence on the date of BCA with any directors, officers and employees of Quidel and its subsidiaries or Ortho and its subsidiaries, as applicable, against all costs or expenses (including reasonable attorney’s fees and disbursements), judgments, inquiries, fines, losses, claims, damages or liabilities incurred by such individual in connection with any civil, criminal, administrative or investigative proceeding arising out of or pertaining to any act or omission of the director, officer or employee of Quidel or its subsidiaries or Ortho and its subsidiaries, as applicable, and (B) without limitation to clause (A), to the fullest extent permitted by law, in each case for acts or omissions occurring at or prior to the Quidel Effective Time (including for acts or omissions occurring in connection with the approval of the BCA and the consummation of the transactions contemplated thereby) (ii) include and cause to be maintained in effect in Topco’s (or any successor’s) organizational documents for a period of at least six years after the Quidel Effective Time, provisions providing for the elimination of liability of directors, indemnification of officers, directors and employees and advancement of expenses to the fullest extent permitted by law and (iii) purchase a six-year “tail” prepaid policy on terms and conditions no less advantageous to the insured than the current directors’ and officers’ liability insurance and fiduciary liability insurance maintained by Quidel and Ortho, as applicable, or with respect to Quidel, continue coverage for the insured under the current Quidel directors’ and officers’ liability insurance and fiduciary liability insurance maintained by Quidel.

For more information on the indemnification and directors’ and officers’ insurance provisions in the BCA, see the section entitled “The Business Combination Agreement—Indemnification and Insurance” in the joint proxy statement/prospectus that forms a part of this registration statement on Form S-4.

1. To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

• To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

• To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the

II-2

information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

• To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

2. That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

4. That, for the purpose of determining any liability under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

5. That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

• Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

• Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

• The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

• Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

6. That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

7. That, prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c) under the Securities Act of 1933, as amended, the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

8. That every prospectus: (i) that is filed pursuant to the immediately preceding paragraph, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933, as amended, and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until

II-3

such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, as amended, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

9. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

10. To respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

11. To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
