SOLICITATION AND VOTING
Voting Securities. Only stockholders of record as of the close of business on March 4, 2025, the record date for the Annual Meeting, will be entitled to vote at the meeting and any adjournment or postponement thereof. As of that date, we had 123,533,310 shares of common stock outstanding, all of which are entitled to vote with respect to all matters to be acted upon at the Annual Meeting. Each stockholder of record as of that date is entitled to one vote for each share of common stock held by him or her. Our Bylaws provide that a majority of all of the shares of the stock entitled to vote, whether present in person or represented by proxy, shall constitute a quorum for the transaction of business at the meeting. When a quorum is present at the meeting, all matters other than the election of directors will be determined by a majority in voting power of the shares present in person or represented by proxy and entitled to vote on the matter. The election of directors will be determined by a majority in voting power of the shares present in person or represented by proxy at the meeting and voting on the matter. Votes for and against, abstentions and “broker non-votes” will each be counted as present for purposes of determining the presence of a quorum.
As permitted by rules adopted by the Securities and Exchange Commission (“SEC”), we are furnishing our proxy statement, 2024 Annual Report to Stockholders and proxy card over the internet to most of our stockholders. This means that most of our stockholders will initially receive only a Notice of Internet Availability of Proxy Materials containing instructions on how to access the proxy materials over the Internet. If you would like to receive a paper copy of the proxy materials, the Notice of Internet Availability of Proxy Materials contains instructions on how you can request copies of these documents at no cost to you.
Voting of Proxies. All valid proxies received before the meeting will be exercised. All shares represented by a proxy will be voted, and where a proxy specifies a stockholder’s choice with respect to any matter to be acted upon, the shares will be voted in accordance with that specification. If no choice is indicated on the proxy provided by a stockholder of record, the shares will be voted for the nominees and for proposals 2 and 3.
You may vote by attending the Annual Meeting online, by using the Internet or telephone to submit a proxy or by completing and returning a proxy by mail, if you requested printed proxy material by mail.
Voting by Internet. To vote by Internet, go to www.proxyvote.com. Internet voting is available 24 hours a day, although your vote by Internet must be received by 11:59 p.m. Eastern Time on April 30, 2025. You will need the control number found either on the Notice of Internet Availability of Proxy Materials or on the proxy card if you are receiving a printed copy of these materials. If you vote by Internet, you should not return your proxy card or voting instruction card. If you hold your shares in “street name” as explained below, please refer to the voting instruction form or notice provided to you by your broker, bank or other holder of record for Internet voting instructions.
Voting by Telephone. To vote by telephone, call 1-800-690-6903 and follow the instructions. Telephone voting is available 24 hours a day, although your vote by telephone must be received by 11:59 p.m. Eastern Time on April 30, 2025. You will need the control number found on your Notice of Internet Availability of Proxy Materials, voting instruction form or on the proxy card if you are receiving a printed copy of these materials. If you vote by telephone, you should not return your proxy card or voting instruction card. If you hold your shares in “street name” as explained below, please refer to the Notice of Internet Availability of Proxy Materials or voting instruction card provided to you by your broker, bank or other holder of record for telephone voting instructions.
Voting by Mail. If you requested printed proxy materials by mail, by completing, signing and returning the proxy card in the prepaid and addressed envelope enclosed with proxy materials delivered by mail, you are authorizing the individuals named on the proxy card to vote your shares at the Annual Meeting in the manner you indicate. You are encouraged to sign and return the proxy card even if you plan to attend the Annual Meeting so that your shares will be voted if you are unable to attend the Annual Meeting. If you receive more than one proxy card, it is an indication that your shares are held in multiple accounts. Please complete, sign and return all proxy cards to ensure that all your shares are voted.
Voting Online During Annual Meeting. You are entitled to participate in the Annual Meeting if you were a shareholder as of the close of business on March 4, 2025, the record date, or hold a legal proxy for the meeting provided by your bank, broker, or nominee. To be admitted to the Annual Meeting at www.virtualshareholdermeeting.com/HALO2025, you must enter the
2

control number found on your Notice of Internet Availability of Proxy Materials, proxy card, or voting instruction form you previously received. You may vote during the Annual Meeting by following the instructions available on the meeting website during the meeting. The meeting’s virtual attendance format will provide you the ability to participate and ask questions in writing during the meeting. Whether or not you plan to participate in the Annual Meeting, we urge you to vote and submit your proxy in advance of the meeting by one of the methods described in the proxy materials for the Annual Meeting. If your shares are registered directly in your name with our transfer agent, EQ by Equiniti, you are considered the stockholder of record and you have the right to vote in person at the Annual Meeting. If your shares are held in the name of your broker or other nominee, you are considered the beneficial owner of shares held in “street name.” Beneficial owners whose stock is held in the name of a bank, broker or other nominee generally will receive instructions for voting from their banks, brokers or other nominees, rather than directly from us. You can vote your shares held through a bank, broker or other nominee by following the voting instructions sent to you by that institution. Shares for which you are the beneficial owner but not the stockholder of record may also be voted electronically during the Annual Meeting.
Revocability of Proxies. A stockholder giving a proxy has the power to revoke it at any time before it is exercised by delivering to the Secretary of Halozyme a written instrument revoking the proxy or by executing a duly executed proxy with a later date, or by attending the Annual Meeting online and voting in person.
Broker Non-Votes. A broker non-vote occurs when a broker submits a proxy card with respect to shares held in street name on behalf of a beneficial owner but is prohibited from voting on a particular matter because the broker has not received voting instructions from the beneficial owner and therefore does not have discretion to vote the beneficial owner’s shares with respect to that matter. Under the rules that govern brokers who are voting with respect to shares held in street name, brokers have the discretion to vote such shares on routine matters, but not on non-routine matters. Routine matters include the ratification of our independent registered public accounting firm. Non-routine matters include the election of directors and the advisory vote on executive compensation matters.
Solicitation of Proxies. We will bear the entire cost of soliciting proxies for the upcoming meeting. In addition to soliciting stockholders by mail through our employees, we will request banks, brokers and other custodians, nominees and fiduciaries to solicit customers for whom they hold our stock and will reimburse them for their reasonable, out-of-pocket costs. We may use the services of our officers, directors and others to solicit proxies, personally or by telephone, without additional compensation.

PROPOSAL NO. 1
ELECTION OF DIRECTORS
We have a classified Board of Directors that currently consists of three Class I directors, two Class II directors and three Class III directors. Our directors are elected for a term of three years, with one class of directors up for election every year. At the 2025 Annual Meeting of Stockholders, we will be electing two Class III directors, while the Class I directors will be elected at the 2026 Annual Meeting of Stockholders and the Class II directors will be elected at the 2027 Annual Meeting of Stockholders.
The Class III nominees recommended by the Board of Directors for election at the 2025 Annual Meeting are: Jeffrey W. Henderson and Helen I. Torley. Mr. Henderson and Dr. Torley are current member of our Board of Directors and, if elected, will serve as directors until our Annual Meeting of Stockholders in 2028 or until their successors are elected and qualified. Ms. Matsui is not standing for re-election and her term will expire as of the meeting date. If any nominee declines to serve or becomes unavailable for any reason, or if a vacancy occurs before the election (although we know of no reason to anticipate that this will occur), the proxies may be voted for such substitute nominees as our Board of Directors may designate.
Majority Voting Standard
Our Bylaws provide that in any election of one or more directors at a meeting at which a quorum is present, other than in a contested election, each director is elected by the vote of a majority of the votes cast by the stockholders with respect to the director. If a director does not receive in an election, other than a contested election, a majority of the votes, the director must tender his or her resignation to the Board of Directors. Within 90 days after the date of the certification of the election results, the Nominating and Corporate Governance Committee of the Board of Directors (or other committee that may be designated by the Board of Directors) will make a recommendation to the Board of Directors on whether to accept or reject the resignation, or whether other action should be taken. The Board of Directors will promptly act on such committee’s recommendation and publicly disclose within four business days on a Current Report on Form 8-K filed with the SEC its decision and the rationale behind such decision.
Vote Required
If a quorum is present at the meeting, election of each of the two nominees for Class III directors requires the vote of a majority of the votes cast by the stockholders with respect to the director at the meeting and voting on the matter. Abstentions and broker non-votes will have no effect on the outcome of the vote.
Recommendation
The Board of Directors recommends a vote “FOR” each of the nominees named above.

16

There are no stated minimum criteria for director nominees. The Nominating and Corporate Governance Committee also believes it is appropriate for at least one key member of management to participate as a member of the Board.
The Halozyme Board of Directors believes that our Board should have diversity of knowledge base, professional experience and skills, and considers director candidates who bring diversity including age, gender, nationality, race, ethnicity and sexual orientation. When considering whether to recommend any candidate for inclusion in the Board’s slate of recommended director nominees, including candidates recommended by our stockholders, the Nominating and Corporate Governance Committee will review the candidate’s integrity, business acumen, age, experience, commitment, diligence, conflicts of interest, existing time commitments and the ability to act in the interests of all stockholders. Once a potential qualified candidate is identified, multiple members of the Nominating and Corporate Governance Committee will interview that candidate. The committee may also ask the candidate to meet with non-committee members of the Board and/or members of management and, if the committee believes a candidate would be a valuable addition to the Board, it will recommend that candidate to the full Board.
Pursuant to the terms of its charter and our Corporate Governance Guidelines, the Nominating and Corporate Governance Committee will consider qualified director candidates suggested by our stockholders. Stockholders may recommend individuals for the Nominating and Corporate Governance Committee to consider as potential director candidates by submitting the candidate’s name, contact information and biographical information in writing to the “Halozyme Nominating and Corporate Governance Committee” c/o Corporate Secretary, 12390 El Camino Real, San Diego, California 92130. The biographical information and background materials of any such candidate will be forwarded to the Nominating and Corporate Governance Committee for its review and consideration. The committee’s review process for candidates identified by our stockholders is essentially identical to the review process for candidates identified by the committee. In addition to the process discussed above regarding the consideration of the Nominating and Corporate Governance Committee of candidates suggested by our stockholders, our Bylaws contain provisions that address the process by which a stockholder may nominate an individual to stand for election to our Board at our Annual Meeting of Stockholders.
Risk Management
Our corporate Enterprise Risk Management program is reviewed approximately quarterly by the CEO and Halozyme Leadership Team, and annually by the Halozyme Board of Directors. Our Board is responsible for reviewing and assessing business enterprise risk and other major risks facing the Company, and evaluating management’s approach to addressing such risks. In connection with these reviews, our Board members rely on information from external sources as well as on their individual experiences identifying and managing business enterprise risk for other entities both within and outside of our industry. In addition, the committees of our Board consider and address risk as they perform their respective committee responsibilities. For example, financial risks and cyber security risks are overseen by our Audit Committee and our Compensation Committee periodically reviews our compensation programs to ensure they do not encourage excessive risk-taking. All committees report to the full Board as appropriate, including when a matter rises to the level of a material or enterprise risk.
Our senior management team is responsible for day-to-day risk management and regularly reports on risks to our full Board or a relevant committee. Our legal, finance and regulatory areas serve as the primary monitoring and evaluation function for company-wide policies and procedures, and manage the day-to-day oversight of the risk management strategy for our business. This oversight includes identifying, evaluating, and addressing potential risks that may exist at the enterprise, strategic, financial, operational, compliance and reporting levels.
We believe the division of risk management responsibilities described above is an effective approach for identifying and addressing the risks facing our Company, and that the leadership structure of our Board is effective in implementing this approach.
Corporate Responsibility
Halozyme continues to build a sustainable, environmentally conscious business while fulfilling our mission of bringing disruptive solutions that can significantly improve patient experiences and potentially outcomes for emerging and established therapies. We are driven by our mission and dedicated to our sustainability efforts across our entire ecosystem internally and externally.
Please see the discussion under the heading “Human Capital Management” in the Business section of our Annual Report on Form 10-K (which accompanies this Proxy Statement) for additional information on our human capital priorities and programs.

Cybersecurity
Our corporate Enterprise Risk Management program, which includes information technology and cybersecurity risk, is reviewed approximately quarterly by the CEO and Halozyme Leadership Team, and annually by the Halozyme Board of Directors. Additionally, Halozyme’s CEO is briefed quarterly and the Audit Committee is briefed periodically, on our cybersecurity program. Our cybersecurity strategy is based on four fundamental areas: policy, procedure, people and technology. Halozyme maintains policies and procedures that describe our employees’ responsibilities for accessing computerized systems, handling data and information, and reporting cybersecurity events in a timely manner. The Board of Directors receives educational updates from outside experts on key emergent topics. All employees and contractors are required to complete formal training on these policies. Halozyme has a well-defined and proven Business Continuity Plan (BCP). The IT Disaster Recovery Plan and the IT Incident Response Plan, which are standalone components of Halozyme’s BCP, provide the framework and guidance to manage risk. Please see the discussion under the heading “Cybersecurity” in the Business section of our Annual Report on Form 10-K (which accompanies this Proxy Statement) for additional information on our cybersecurity risk management, strategy and governance.

Please read the Executive Compensation and Related Information section of this Proxy Statement for a detailed discussion about our executive compensation programs, including information about the fiscal year 2024 compensation of our Named Executive Officers. Accordingly, as required by Section 14A of the Securities Exchange Act of 1934, as amended, we are asking our stockholders to cast an advisory vote to approve the executive compensation as described in this Proxy Statement. We expect to conduct the next advisory vote on the compensation of our Named Executive Officers at our 2026 Annual Meeting of Stockholders
We have many compensation practices that ensure consistent leadership, decision-making and actions without taking inappropriate or unnecessary risks. These compensation practices are discussed in detail in the Compensation Discussion and Analysis section of this Proxy Statement and have the following objectives:
•Properly align the interests of our stockholders with those of our executive leadership team;
•Reward actions and achievements that are consistent with the short- and long-term goals of Halozyme’s business strategy; and
•Remain competitive to attract, retain and motivate employees with relevant experience and skills needed to achieve our business goals.
The vote solicited by this Proposal No. 2 is advisory, and therefore is not binding on the Company, our Board of Directors or our Compensation Committee, nor will its outcome require the Company, our Board of Directors or our Compensation Committee to take any action. Moreover, the outcome of the vote will not be construed as overruling any decision by the Company, the Board of Directors or the Compensation Committee. However, our Board of Directors, including our Compensation Committee, values the opinions of our stockholders and, to the extent there is any significant vote against the Named Executive Officer compensation as disclosed in this Proxy Statement, we will consider our stockholders’ concerns and evaluate what actions, if any, may be appropriate to address those concerns.
Stockholders will be asked at the Annual Meeting to approve the following resolution pursuant to this Proposal No. 2:
RESOLVED, that the stockholders of Halozyme Therapeutics, Inc. approve, on an advisory basis, the compensation of the Company’s Named Executive Officers, disclosed pursuant to Item 402 of Regulation S-K in the Company’s Definitive Proxy Statement for the 2025 Annual Meeting of Stockholders.
Vote Required
Approval of this resolution requires the affirmative vote of a majority in voting power of the shares present in person or represented by proxy at the meeting and entitled to vote on the matter. Abstentions will be treated as votes “against” the proposal. Broker non-votes will have no effect on the outcome of the vote.
Recommendation
The Board of Directors believes that the compensation of our Named Executive Officers, as described in the Compensation Discussion and Analysis and the tabular disclosures and accompanying narrative disclosures under the heading “Executive Compensation and Related Information” is appropriate for the reasons stated above. Therefore, the Board of Directors unanimously recommends a vote “FOR” approval of the compensation for our Named Executive Officers.

REPORT OF THE AUDIT COMMITTEE
The Audit Committee oversees the Company’s financial reporting process on behalf of the Board of Directors and is comprised solely of independent directors as defined by the Nasdaq listing standards and Rule 10A-3 of the Securities Exchange Act of 1934. The Audit Committee is governed by a charter which describes in greater detail the full responsibilities of the Audit Committee. The Company’s management has the primary responsibility for the consolidated financial statements, for maintaining effective internal control over financial reporting, and for assessing the effectiveness of internal control over financial reporting. In fulfilling its oversight responsibilities, the Audit Committee reviews the consolidated financial statements, internal control over financial reporting, audit matters and reports from management. In connection with these reviews, the Audit Committee meets with management and the independent registered public accounting firm (Ernst & Young LLP) at least once each quarter. These meetings include, whenever appropriate, executive sessions in which the Audit Committee meets separately with the independent registered public accounting firm, internal auditors, management personnel and legal counsel. The meetings of the Audit Committee are designed to facilitate and encourage communication among the Audit Committee, the Company, the Company’s internal audit function and the independent registered public accounting firm. The Audit Committee is directly and solely responsible for the appointment, compensation, retention, and oversight of the independent registered public accounting firm. The Audit Committee regularly considers the independence, qualifications, audit and non-audit fees and services, and performance of the independent registered public accounting firm.
The Audit Committee has reviewed and discussed with the independent registered public accounting firm, which is responsible for expressing an opinion on the conformity of the audited consolidated financial statements with U.S. generally accepted accounting principles, its judgments as to the quality, not just the acceptability, of the Company’s accounting principles and such other matters as are required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (PCAOB) and the Securities and Exchange Commission, and other applicable regulations. In addition, the Audit Committee reviewed and discussed with Ernst & Young LLP matters related to its independence, including a review of non-audit services and the written disclosures and the letter from Ernst & Young LLP to the Audit Committee required by the PCAOB regarding its communications with the Audit Committee concerning Ernst & Young LLP’s independence. The Audit Committee concluded that Ernst & Young LLP is independent from the Company and its management.
The Audit Committee discussed with the Company’s independent registered public accounting firm the overall scope and plans for their respective audits. The Audit Committee has met the independent registered public accounting firm, with and without management present, to discuss the results of their examinations; their evaluations of the Company’s internal control, including internal control over financial reporting; the critical audit matters addressed during the audit; and the overall quality of the Company’s financial reporting.
The Committee also reviewed and discussed with management and the independent registered public accounting firm the Company’s audited consolidated financial statements and related schedule, the results of management’s assessment of the effectiveness of the Company’s internal control over financial reporting and the independent registered public accounting firm’s audit of internal control over financial reporting for the year ended December 31, 2024.
In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors, and the Board of Directors has approved, that the audited consolidated financial statements and management’s assessment of the effectiveness of the Company’s internal control over financial reporting be included in the Annual Report on Form 10-K for the year ended December 31, 2024 filed by the Company with the Securities and Exchange Commission.

EXECUTIVE COMPENSATION AND RELATED INFORMATION
COMPENSATION DISCUSSION AND ANALYSIS
Executive Summary
The Compensation Committee oversees the compensation program for the Company’s executive officers. In this role, the Compensation Committee reviews and approves all compensation decisions relating to our executive officers listed in the table below (referred to in this proxy statement as our “Named Executive Officers” or “NEOs”).
Our NEOs for 2024 are:

Name |  | Principal Position
Helen I. Torley |  | President and Chief Executive Officer
Nicole LaBrosse |  | Senior Vice President, Chief Financial Officer
Mark Snyder |  | Senior Vice President, Chief Legal Officer
Michael J. LaBarre |  | Senior Vice President, Chief Technical Officer

Executive Compensation Highlights
Our executive compensation program ties a substantial portion of each executive’s overall compensation to the achievement of key strategic, financial and operational goals and aligns the interests of executive officers with stockholders by annually awarding long-term equity-based incentives (“LTI”), in the form of time-vesting restricted stock units (“RSUs”), performance-vesting stock units (“PSUs”) and stock options. Consistent with this approach, the compensation of our NEOs for 2024 featured:
•Total Revenue from Existing Sources 1, New Revenue 1, and Adjusted EBITDA 1 growth performance goals were established for the threshold, base and maximum targets under our 2024 annual cash incentive program. Actual Total Revenue from Existing Sources attainment was $957.5 million, a 16% increase over prior year which was 200% to target, New Revenue attainment was $27 million, which was 71.3% to target, and Adjusted EBITDA was $601.4 million a 41% increase over prior year and 200% to target. Actual cash payouts under the 2024 annual cash incentive program ranged from 95% to 189% of target, with the cash payouts driven by a corporate performance factor under the program of 157.8%.
•a compensation package more heavily weighted toward long-term equity-based incentive compensation than salary and shorter-term annual cash incentives in order to emphasize the focus on our long-term performance and stockholder value,
•long-term equity-based incentives that were heavily weighted toward performance – in addition to the value of all awards being dependent on our stock price, the annual awards granted in 2024 consisted of 50% PSUs which are subject to performance-based vesting conditions, 15% stock options, which have value only if our stock price increases after the date of grant of the awards, and 35% RSUs, the value of which depends on our future stock price when the awards vest,
•stock ownership and stock retention guidelines, encouraging executives to maintain a meaningful ownership position in the Company, focus on our long-term performance and discourage unreasonable risk-taking,
•a recoupment (or “claw back”) policy covering certain compensation elements in the event of an accounting restatement due to material noncompliance with any financial reporting requirements,
•a practice of not including tax gross-ups in ongoing compensation arrangements,
•no “single trigger” provisions in executive and employee change-in-control agreements and arrangements (i.e., payout or vesting is not triggered automatically upon a change-in-control), and
•no material perquisites.
1 We use “Total Revenue from Existing Sources” in this Compensation Discussion and Analysis (“CD&A”) to mean the Company’s total revenue for the year excluding New Revenue. We use “New Revenue” in this CD&A to mean the Company’s revenue for the year derived from new collaborations, milestones, and nominations that were not in the Company’s base financial plan for the year and were the result of new opportunity creation. We use “Adjusted EBITDA” in this CD&A to refer to the Company’s earnings for the year excluding interest, taxes, depreciation and amortization, and excluding one time items, if any, such as changes in contingent liabilities, inventory adjustments, and impairment charges that we feel are not reflective of our core operating performance. Total Revenue from Existing Sources and Adjusted EBITDA do not include revenue we received during the year resulting from the issuance of the European patent we were granted in June 2024 covering ENHANZE® manufacturing methods which prevented the reduction in the royalty rate on sales of DARZALEX® SC in the European countries where it is validated. This additional revenue was not included at the time the corporate goals were established as it was dependent upon patent issuance, and it was determined that if a patent was issued, the incremental revenue would be excluded from the performance measurement.

Stockholder Engagement
The Board and the Compensation Committee value the input of our stockholders regarding the Company’s governance practices and the design and effectiveness of our executive compensation program. Halozyme conducts regular outreach to our stockholders to build relationships and solicit feedback on these topics.
In addition, our stockholders are provided with an opportunity to cast an advisory vote on our executive compensation program every year through the “say-on-pay” proposal. At our 2024 annual meeting of stockholders, our stockholders approved, on a non-binding, advisory basis, the compensation paid to our NEOs described in our 2024 proxy statement. Approximately 97.9% of the votes cast on the matter were voted in favor of this “say-on-pay” proposal. The Compensation Committee considered the voting results and high level of stockholder support of the prior year when establishing our executive compensation programs for fiscal 2025.
When making future compensation decisions for our executive officers, the Compensation Committee will continue to consider the opinions that stockholders express through our stockholder engagement program and through our annual “say-on-pay” advisory votes.
2024 Business Highlights
Halozyme’s strong financial and operating performance in 2024 was supported by internal corporate developments and significant growth and advancements with our ENHANZE® collaboration partners. The key developments and achievements in 2024 include:
•Strong stockholder return, with the per share price of our common stock up 28% during 2024 (from NASDAQ closing price of $37.39 on January 2, 2024 to a NASDAQ closing price of $47.81 on December 31, 2024) and up 223% over five years (from a NASDAQ closing price of $14.80 on January 2, 2019 to a NASDAQ closing price of $47.81 on December 31, 2024).
•Reported record total revenues of $1,015.3 million, which increased 22% from $829.3 million in 2023.
•Revenues from royalties of $571 million which increased 27% from $447.9 million in 2023 driven primarily by continued sales uptake of DARZALEX® subcutaneous (“SC”) from Janssen and Phesgo® by Roche in all geographies, and the prior year launch of VYVGART® Hytrulo by argenx.
•In June 2024, the Company completed the $250 million Accelerated Share Repurchase (“ASR”) that was initiated in November of 2023, resulting in a total repurchase of 6.5 million shares at an average price of $38.35 per share which concluded our December 2021 share repurchase program resulting in a total of 19.1 million shares repurchased over the three-year period at an average price per share of $39.31.
•The Company announced the issuance of a new European patent covering the ENHANZE® rHuPH20 product obtained from our ENHANZE® manufacturing methods that we provide to our licensees. The newly granted patent maintains the original royalty rate on sales of DARZALEX® SC in 37 European countries until expiration of the patent in March 2029.
•argenx expanded its global collaboration and license agreement nominating four additional targets that provides them exclusive access to our ENHANZE® drug delivery technology for a total of six targets. Under the terms of the expanded exclusive agreement, we received upfront payments of $7.5 million per target nomination for a total of $30.0 million. argenx is obligated to make future milestone payments of up to $85.0 million per new nominated target, subject to achievements of specified development, regulatory and sales-based milestones. We are also entitled to receive royalties on net sales of commercialized products with our ENHANZE® technology.
•ViiV expanded its global collaboration and license agreement providing ViiV the ability to exclusively access our ENHANZE® drug delivery technology for one additional undisclosed target.

2024 CEO Compensation
In 2024, the total target annual cash compensation for our CEO, Dr. Helen I. Torley, was $1,824,000 ($960,000 in base salary plus $864,000 in target annual cash incentive opportunity). Dr. Torley’s base salary was increased for 2024 by 4.3% as a result of the Compensation Committee’s assessment of her contribution to Halozyme’s performance during 2023 and its review of base salary paid to other peer group CEOs. See Competitive Peer Group below. Dr. Torley’s target annual cash incentive opportunity for 2024 (assuming achievement of the corporate goals at 100%) was 90% of her base salary, which was the same percentage of her base salary as her target annual cash incentive opportunity for 2023. The Compensation Committee believes this target annual cash incentive was appropriate based on her level of experience, the Compensation Committee’s review of the annual cash incentive target for other peer group CEOs, and the Compensation Committee’s belief that significant portions of total annual cash compensation should be tied to achievement of specified goals. As discussed in more detail below in this CD&A, the annual cash incentive she earned for 2024 was $1,363,392 which represents approximately 157.8% of her target annual cash incentive opportunity. As CEO, Dr. Torley is the only NEO whose annual cash incentive is determined solely based on the performance of the Company.
Dr. Torley also received a LTI award during 2024 that had a grant date fair value of approximately $10,400,000, comprising the most significant element of her 2024 compensation opportunity. This award was granted based on the Compensation Committee’s assessment of her contribution to Halozyme’s performance during 2023, its review of LTI compensation paid to other peer group CEOs and the desire to link a significant portion of her compensation opportunity to Halozyme’s long-term performance. The Compensation Committee approved a mix of 50% PSUs (at target), 15% stock options and 35% RSUs for Dr. Torley, and the same mix for the annual LTI awards for each of the other NEOs, to emphasize Halozyme’s long-term stock price performance and to promote retention. The LTI award mix placed a particular emphasis on performance as the 50% allocation of Dr. Torley’s total LTI award to PSUs represented a significant increase over the 28.75% allocation to PSUs in 2023. The PSUs granted to Dr. Torley and the other NEOs in 2024 cliff vest aftter three years. One-half of the PSUs vest based on our relative total shareholder return (“TSR”) measured against an applicable subset of companies in the NASDAQ Biotechnology Index over a three-year performance period and the remaining one-half of the PSUs vest based on new collaboration deals and nominations during 2024 as described in more detail under “LTI Compensation” below. The stock options have a maximum term of ten years and vest 25% on the one-year anniversary of the date of grant with the remaining 75% vesting monthly over the following three years, while RSUs vest in 25% annual installments over a four-year period following the grant date, in each case subject to continued employment.
Halozyme’s Executive Compensation Program
The principal elements of our executive compensation program are base salary, an annual cash incentive opportunity and an annual LTI award opportunity. The LTI awards for 2024 consisted of stock options, RSUs and PSUs.

Detailed Discussion and Analysis
This CD&A describes the material elements of 2024 compensation for our NEOs.
The Compensation Committee makes all decisions relative to the compensation of all executive officers (including the CEO). Except as otherwise noted in this CD&A, the Compensation Committee’s executive compensation determinations are subjective and the result of the Compensation Committee’s business judgment. Additional details regarding the role and responsibilities of the Compensation Committee are provided below.
Executive Total Rewards Philosophy
The Compensation Committee periodically reviews its total rewards philosophy for executive officers to confirm our programs continue to meet the objectives of:
•supporting Halozyme’s short- and long-term business strategy,
•anchoring to market-based principles and being tailored to Halozyme’s culture, and
•aligning the interests of the executive officers with the long-term interests of Halozyme stockholders.
26

The 2024 compensation for our NEOs consisted of three primary elements, each having a specific purpose as described below:

Compensation Element | Purpose
Base Salary | • Provides a fixed amount of cash compensation for services rendered based on individual performance, job scope, experience and competitive market for talent
Annual Cash Incentive | • Motivates and rewards fiscal year contribution to company performance against pre-established financial and operational goals and objectives
Long-term Incentives | • Align compensation with the creation of stockholder value (as the value of equity awards generally, and stock options in particular, depends on stock price) and, in the case of PSUs, the achievement of relative total shareholder return goals and other performance objectives we consider important to our long-term success • Increase executive stock ownership and alignment with stockholder interests. • Serve as a key retention device

In addition, our NEOs are eligible to receive severance payments and benefits in connection with a qualifying termination of employment under our executive Change-in-Control Agreements and our severance policy for covered terminations unrelated to a change in control, each as described in more detail below. We also provide our NEOs with the same package of benefits that are provided to substantially all our full-time employees, including Company matching contributions to a 401(k) plan, health insurance, group term life insurance, and disability income insurance. From time to time, we may also provide relocation assistance in connection with the recruitment of an employee with needed skills and experience. No material perquisites or supplemental executive benefits were provided to our NEOs in 2024.
As shown below, the majority of our NEOs’ target total direct compensation for 2024 (base salary, target annual cash incentive, and LTI awards, taken into account at their fair value on the grant date) was variable (target annual cash incentive and LTI awards), with the single largest component (LTI awards) based on Halozyme’s stock price performance.
27

Base Salary
The Compensation Committee determines base salaries for NEOs each year based upon the following factors (with no specific weight applied to each factor):
•the scope and complexity of the NEO’s responsibilities,
•a review of external market practices (a more detailed description of the methodology used to assess external market practices is provided below),
•the NEO’s experience,
•internal pay equity, and
•the CEO’s evaluation of the NEO’s performance and contribution to the short- and long-term success of Halozyme (in the case of the CEO, the evaluation is done in executive session by the Compensation Committee with input from the other independent members of the Board of Directors).
As reflected in the table below, 2024 annual base salary levels were increased by 4.3% for the CEO, between 3.3% and 6.0% for the other NEOs. The base salary increases for our NEOs were approved by the Compensation Committee after taking into account the base salaries paid to peer group executives holding similar positions and other factors described above.
28

Executive Officer |  | 2023 Base Salary ($) |  | 2024 Base Salary ($) |  | % Increase
Helen I. Torley |  | 920,000 |  | 960,000 |  | 4.3%
Nicole LaBrosse |  | 546,188 |  | 568,188 |  | 4.0%
Mark Snyder |  | 546,000 |  | 579,000 |  | 6.0%
Michael J. LaBarre |  | 538,200 |  | 556,200 |  | 3.3%

Annual Cash Incentive
NEOs participate each year in the Employee Bonus Plan (“EBP”). The actual cash incentive paid to each NEO with respect to 2024 was determined based on each NEO’s target annual cash incentive opportunity and based on the performance of Halozyme as measured by the level of achievement of six metrics, of which three are tied to financial performance and have a combined 80% weighting and three are tied to operational performance and have a combined 20% weighting (“Corporate Performance”). As CEO, Dr. Torley is responsible for overall corporate performance, and accordingly, her EBP incentive opportunity is based entirely on the attainment of objective, pre-established corporate performance goals without applying an individual performance adjustment. For the other NEOs, the Compensation Committee may modify final payouts based on individual performance during the year relative to the level of achievement of personal goals (“Individual Performance Factor”), and the NEO must achieve at least 60% of his/her individual performance objectives in order to be eligible for a cash incentive payment. In all events, an NEO’s total payout cannot exceed two times the target cash annual incentive opportunity for the NEO.
The Compensation Committee sets each NEO’s target annual cash incentive opportunity as a percentage of the NEO’s base salary taking into account the same factors as are considered in NEO base salary determinations. As shown in the chart below, no changes were made to target annual cash incentive opportunities for the NEOs in 2024 (as a percentage of base salary).

Executive Officer |  | 2023 Target Bonus (% Salary) |  | 2024 Target Bonus (% Salary) |  | 2024 Target Bonus ($)
Helen I. Torley |  | 90% |  | 90% |  | 864,000
Nicole LaBrosse |  | 50% |  | 50% |  | 284,094
Mark Snyder |  | 50% |  | 50% |  | 289,500
Michael J. LaBarre |  | 50% |  | 50% |  | 278,100

Corporate Performance. Corporate goals were established by the Compensation Committee (with input from the full Board of Directors) to tie the compensation of our NEOs to the Company’s achievement of annual operating objectives that were viewed as long-term drivers of sustainable value creation. EBP funding ranges between 0% and 200% for each of the six metrics. The Board of Directors approved the threshold, target, and maximum goals/level of performance for each metric.
The 2024 EBP focused on achievement of key financial and strategic objectives that resulted in (i) growth in Total Revenue from Existing Sources, (ii) New Revenue, (iii) increased Adjusted EBITDA and (iv) certain other operational goals as identified in the table below. The Compensation Committee is responsible for certifying actual performance relative to these goals following completion of the fiscal year. After reviewing the Company’s performance results in 2024, the Compensation Committee determined the corporate performance factor under the 2024 EBP was achieved at 157.8% of the targeted level for the NEOs (see table below). We used growth in revenues and Adjusted EBITDA as financial performance measures under the 2024 EBP because they are common metrics used to measure performance and widely understood by investors.
29

Corporate Goal | Weight | Threshold 50% | Target 100% | Maximum 200% | Actual Result | EBP Funding
Total Revenue from Existing Sources | 40% | $865.0M | $897.0M | $935.0M | $957.5M | 80%
New Revenue | 25% | $10M | $50M | $75M | $27M | 17.8%
Adjusted EBITDA | 15% | $495M | $561M | $586M | $601.4M | 30%
Demonstrate operational excellence through achievement of key performance metrics related to production and release | 10% | 3 of 5 | 4 of 5 | 5 of 5 | Achieved 4 KPIs | 10%
Achieve new patent filings | 5% | 2 | 4 | 6 | 6 | 10%
Achieve HVAI clinic readiness | 5% | Achieved between May 1 and June 1 | Achieved between April 2 and April 30 | Achieved on or before April 1 | Achieved on March 19 2024 | 10%
TOTAL CORPORATE PERFORMANCE FACTOR | 157.8%

Individual Performance Factor. The Compensation Committee believes the actual payout to each NEO (other than for Dr. Torley whose payout, as noted above, is based entirely on the attainment of objective, pre-established corporate performance goals) should also reflect the executive’s:
•performance relative to individual goals and objectives established for the year,
•contribution toward achieving the Corporate Performance results, and
•demonstration of living Halozyme’s Leadership Attributes and Corporate Values during the year.
Weighing Ms. LaBrosse’s accomplishments and other factors, the Compensation Committee supported the CEO’s recommendation and awarded her an individual performance factor of 120%. The Compensation Committee noted that:
•Ms. LaBrosse successfully led several strategic initiatives and activities, including financial transactions (including completion of the $250 million ASR in the second quarter of 2024, and the initiation of the $250 million ASR in December 2024), continued actions to optimize taxes, further evolution of our cybersecurity readiness and multiple strategic financial analyses related to capital allocation and deployment.
Weighing Mr. Snyder’s accomplishments and other factors, the Compensation Committee supported the CEO’s recommendation and awarded him an individual performance factor of 120%. The Compensation Committee noted that:
•Mr. Snyder played a key leadership role in successful issuance of a new European ENHANZE® rHuPH20 product obtained from our ENHANZE® manufacturing methods that we provide to our licensees that resulted in maintenance of a key royalty revenue stream at the original rate, extending the time to royalty rate step down from 2024 to 2029. In addition, he oversaw the submission of multiple new patent applications related to Halozyme’s drug delivery technologies.
Weighing Dr. LaBarre’s accomplishments and other factors, the Compensation Committee supported the CEOs recommendation and awarded him an individual performance factor of 60%. The Compensation Committee noted that:
•While Dr. LaBarre played a key role in the successful accomplishment of the HVAI clinic readiness goal and helped identify innovations that supported multiple new patent applications, full progress related to an internal revenue goal was not accomplished.
The table below illustrates the 2024 cash incentive calculation for each NEO based on the following formula (also reflected in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table).

________________
(1)As noted above, Dr. Torley’s payout is based entirely on the attainment of objective, pre-established corporate performance goals without applying an individual performance factor.
LTI Compensation
All grants of LTI compensation are made under our stockholder-approved equity incentive plan. The Compensation Committee utilized three vehicles to deliver LTI awards to NEOs during 2024:
Stock Options are strongly aligned with stockholder interests because they deliver value to the NEO only if the value of our stock at the time of exercise exceeds the stock price on the day of grant. As a result, the Compensation Committee believes stock options encourage executives to focus on the decisions and behaviors required to support long-term sustainable increases in our stock price.
Time-vesting RSUs provide a counterbalance to the more uncertain value associated with stock options and PSUs while still maintaining alignment with the interests of our long-term stockholders, as the value of RSUs fluctuates (up or down) with changes in our stock price. As a result, the Compensation Committee believes time-vesting RSUs encourage executives to make decisions consistent with the long-term interests of our stockholders and help support retention.
Stock options and time-vesting RSUs granted to our NEOs in 2024 generally vest over a four-year period subject to continued employment.
PSUs help link our equity incentive program to achievement of specific performance goals established by the Compensation Committee. The Compensation Committee believes that the grant of PSUs furthers our executive compensation philosophy to tie achievement of company performance with executive compensation, aligns the interests of executive officers with our stockholders and encourages long-term performance.
The PSUs granted to the NEOs in 2024 are eligible to cliff vest after a three-year period following the grant date provided they are earned based achievement of the applicable performance goals. The NEOs were granted two types of PSU awards for 2024: PSUs that are eligible to vest based on our relative TSR over a three-year performance period (“Relative TSR PSUs”), and PSUs that are eligible to vest based on new collaboration deals and nominations during 2024 (“Deal/Nomination PSUs”).
Relative TSR PSUs. To determine the vesting of Relative TSR PSUs, our TSR performance is measured against the component companies of the NASDAQ Biotechnology Index (excluding companies that had not been listed or traded on a national securities exchange for at least three consecutive years as of October 31, 2023, those that had gross revenue of less than $100 million for the period of four consecutive calendar quarters ending with the last fiscal quarter for which there were publicly disclosed financial results as of October 31, 2023, and those that cease to be publicly-traded during the applicable performance period other than due to insolvency).
One-third of the target Relative TSR PSUs are earned based on performance over three discrete performance periods each beginning on the grant date of the awards, with one performance period ending December 31, 2024, one performance period ending December 31, 2025, and one performance period ending December 31, 2026. For purposes of these awards, TSR for Halozyme and the applicable subset of component companies is based on a 20-trading day average trading price beginning on the PSU grant date and a 20-trading day average trading price ending on the last day of the applicable performance period. Dividend equivalents, if any, will be accrued as additional stock units and delivered with earned shares at vesting. The potential vesting percentages for the 2024 Relative
31

TSR PSUs, as determined for each performance period and to be applied to the target number of PSUs allocated to that performance period, are as follows (with the percentage determined by linear interpolation for performance between the 25 th and 75 th percentiles):

Maximum | 75 th Percentile or Higher | 150%
Target | 50 th Percentile | 100%
Threshold | 25 th Percentile | 50%
Below Threshold | < 25 th Percentile | 0%

Relative TSR PSUs eligible to vest based on performance become vested on the third anniversary of the grant date of the award following certification of performance results and subject to continued employment through the vesting date. The three-year cliff vesting schedule serves as an additional retention incentive and incentive for stock price performance for the entire three-year period covered by the Relative TSR PSUs to support long-term alignment with our stockholders.
Deal/Nomination PSUs. Performance for the Deal/Nomination PSUs is measured based on the number of “points credited” for new Company deals and nominations, with points earned based on the occurrence of the following events in 2024: (a) a new collaboration deal signed by the Company for SVAI (2.5ml or less, does not include ENHANZE®) (an “SVAI Deal”), (b) a new collaboration deal signed by the Company to add HVAI to an existing nominated target (a “HVAI Deal Added to Existing ENHANZE® Target”), (c) a new target nomination under an existing collaboration for any delivery offering by the Company (SVAI, HVAI, or ENHANZE® only) (a “New Nomination”), and (d) a new collaboration deal signed by the Company for ENHANZE® on its own, or ENHANZE® with HVAI (a “New ENHANZE® +/- HVAI Deal”).
The total number of points credited for 2024 is then used to determine the vesting percentage of the Deal/Nomination PSUs, to be applied to the target number of PSUs for the award, as follows (with the percentage determined by linear interpolation if the number of points credited is between 5 and 20):

Deal/Nomination Points Credited for 2024 | Vesting Percentage
Less than 5 | 0%
5 | 50%
10 (“target”) | 100%
15 | 150%
20 or more | 200%

Deal/Nomination PSUs eligible to vest based on performance become vested on the third anniversary of the grant date of the award, subject to continued employment through the vesting date. The three-year cliff vesting schedule serves as an additional retention incentive and incentive for stock price performance for the entire three-year period covered by the Deal/Nomination PSUs to support long-term alignment with our stockholders.
2024 Annual LTI Awards
For 2024, the Compensation Committee awarded annual LTI compensation for the NEOs based on the grant date value the Committee determined appropriate considering their assessment of annual equity award grants to peer group executives holding similar positions, and taking into account their assessment of the executive’s experience, expected contribution to the long-term success of the Company, and skill-set relative to industry peers at biopharmaceutical companies (with no specific weight applied to each factor). The Compensation Committee also determined that the annual award value for each NEO would be allocated 50% PSUs (at target), 15% in stock options and 35% in RSUs. A greater weight was placed on PSUs in the NEOs’ equity award mix for 2024 as compared to 2023 (50% for 2024 compared to 28.75% for Dr. Torley and 25% for the other NEOs for 2023) to increase the performance-based portion of their overall LTI award. Accordingly, the Compensation Committee awarded the following LTI values to our NEOs in 2024:

Name |  | Option Awards ($) |  | RSUs ($) |  | PSUs ($) |  | Total ($)
Helen I. Torley |  | 1,560,000 |  |  | 3,640,000 |  |  | 5,200,000 |  |  | 10,400,000
Nicole LaBrosse |  | 465,000 |  |  | 1,085,000 |  |  | 1,550,000 |  |  | 3,100,000
Mark Snyder |  | 487,500 |  |  | 1,137,500 |  |  | 1,625,000 |  |  | 3,250,000
Michael J. LaBarre |  | 330,000 |  |  | 770,000 |  |  | 1,100,000 |  |  | 2,200,000

For each NEO, half the target PSU value was awarded in the form of Relative TSR PSUs and half the target PSU value was awarded in the form of Deal/Nomination PSUs. For each NEO, the LTI value allocated to an award was converted into a number of shares based on (i) in the case of RSUs and the target number of Deal/Nomination PSUs, the closing price of our stock on the grant
32

date, and (ii) in the case of options and the target number of Relative TSR PSUs, the per-share fair value of the award on the grant date awards as determined under applicable accounting rules, and rounding up to a whole share. The grant date fair value of the options was determined using the Black-Scholes option valuation methodology. The grant date fair value of the Relative TSR PSUs was determined using a Monte Carlo simulation. Differences between the LTI values approved by the Compensation Committee, as shown above, and the actual grant date fair values of the awards as included in the executive compensation tables following the CD&A are due to the rounding of fractional share interests in accordance with the methodology approved by the Compensation Committee.
June 2024 RSU Award for Mark Snyder
In addition to the awards discussed above, on June 12, 2024 the Company awarded Mr. Snyder a grant for approximately $1,000,000 in RSUs to recognize Mr. Snyder’s significant contributions to the Company’s issuance of a new European patent covering the ENHANZE® rHuPH20 product obtained from our ENHANZE® manufacturing methods that we provide to our licensees that resulted in maintenance of a key royalty revenue stream at the original rate. One-fourth of these RSUs are scheduled to vest on the first anniversary of the grant date and then one-fourth on each anniversary of the grant date thereafter.
PSU Award Vesting
The Compensation Committee has determined that, as to the one-third of the Relative TSR PSUs awarded in 2024 that correspond to a performance period ended December 31, 2024, 131.18% of such PSUs are eligible to vest based on our relative TSR measured against the applicable subset of component companies of the NASDAQ Biotechnology Index for that period (our TSR for that period was 17.6% and this placed us at the 65.59 th percentile against the comparison group of companies for that period). In addition, the Compensation Committee determined that, as to the Deal/Nomination PSUs awarded in 2024, 5 new nominations had occurred during 2024, resulting in 15 points being credited for such deals and nominations as described above and, accordingly, that 150% of such PSUs are eligible to vest. The PSUs subject to each of these Relative TSR PSU and Deal/Nomination PSU awards remain unvested, with vesting subject to continued employment through the third anniversary of the grant date of the awards.
We awarded PSUs to each of the NEOs in 2022 and 2023 that are similar to the Relative TSR PSUs awarded in 2024 described above. The Compensation Committee has determined that, as to the one-third of the PSUs awarded in 2022 that correspond to a three-year performance period ended December 31, 2024, 150% of such PSUs are eligible to vest based on our relative TSR measured against the applicable subset of component companies of the NASDAQ Biotechnology Index for that period (our TSR for that period was 37.7% and this placed us at the 77.92 nd percentile against the comparison group of companies for that period). The PSUs vested on the third anniversary of the grant date of the awards. The Compensation Committee has also determined that, as to the one-third of the PSUs awarded in 2023 that correspond to a two-year performance period ended December 31, 2024, 124.14% of such PSUs are eligible to vest based on our relative TSR measured against the applicable subset of component companies of the NASDAQ Biotechnology Index for that period (our TSR for that period was 5.2% and this placed us at the 62.07 th percentile against the comparison group of companies for that period). These PSUs remain unvested, with vesting subject to continued employment through the third anniversary of the grant date of the awards.
Competitive Peer Group
The Compensation Committee annually selects a group of peer companies against which Halozyme benchmarks the competitiveness of executive pay levels and program design (referred to in this CD&A as our “peer group” or “peer companies”). The peer group companies are identified based upon the Compensation Committee’s assessment of each company’s similarity with Halozyme with respect to science/business model, revenue, and market capitalization. The peer group is reviewed annually by the Compensation Committee.
For 2024 compensation decisions, the Compensation Committee utilized proxy data from the following companies, listed below. The Compensation Committee’s objective in selecting this peer group was to include a group of similar-sized public companies in the life sciences sector, with an emphasis on pharmaceutical and biotechnology companies with commercialized products. Targeted companies generally had revenues and market capitalization between 0.25x to 4.0x Halozyme’s size at the time of the analysis with Halozyme near the median on both measures.

2024 Peer Group
Acadia Pharmaceuticals Alkermes Alnylam Pharmaceuticals Amicus Therapeutics BeiGene BioMarin Pharmaceutical | Blueprint Medicines Exelixis Insmed Ionis Pharmaceuticals Ironwood Pharmaceuticals Ligand Pharmaceuticals | Neurocrine Biosciences PTC Therapeutics Sarepta Therapeutics Ultragenyx Pharmaceuticals United Therapeutics

33

The following changes to the peer group were made for 2024:
•BeiGene, Insmed, and PTC Therapeutics were added to the group based on the Compensation Committee’s assessment of the criteria noted above.
•Agios Pharmaceuticals was removed from the group based on the Compensation Committee’s assessment that it no longer met the revenue and market capitalization criteria.
Independent Compensation Consultant
The Compensation Committee retains F.W. Cook & Co., Inc. (“FW Cook”) as its independent compensation consultant to provide advice and counsel on matters related to our executive and non-employee director compensation program and FW Cook provides no other services to Halozyme. In 2024, FW Cook provided recommendations regarding the composition and selection of Halozyme’s peer group companies to be used with respect to 2024 and 2025 executive compensation decisions, performed a review of compensation levels and practices for similar executive positions at the peer group companies, advised regarding the compensation mix and levels for the NEOs, advised on the design and implementation of our annual LTI awards, reported on executive compensation trends and developments, and advised on the compensation arrangements for our non-employee directors. FW Cook reports directly to the Compensation Committee and regularly attends meetings of the Compensation Committee, as requested. The Compensation Committee assessed the independence of FW Cook pursuant to applicable rules and regulations of the SEC and NASDAQ and concluded that the engagement of FW Cook did not raise any conflicts of interest during fiscal 2024 and currently does not raise any conflicts of interest.
Compensation Risk Assessment
Our Compensation Committee, with assistance from its independent compensation consultant and with input from members of management, annually reviews our compensation programs, policies and practices to determine whether they encourage risk-taking that could have a material adverse effect on the Company. As part of this review, the Company evaluates the primary components of its compensation programs to identify whether those components properly balance compensation opportunities and risk. Our Compensation Committee considers various factors, including the following:
•The Company’s pay philosophy provides an effective balance in cash and equity award mix, short- and long-term performance periods, financial and non-financial performance, formulas and discretion.
•The Company’s compensation programs include an appropriate mix of short- and long-term goals and incentives.
•The Compensation Committee has the discretion to make positive and negative adjustments to payouts under the Company’s compensation plans.
•Policies are in place to manage or mitigate risk, such as stock ownership guidelines, vesting periods on equity awards, insider-trading prohibitions that also restrict hedging and pledging, recoupment policy and provisions, and independent Compensation Committee oversight.
•The Company’s design and oversight principles also apply to its broad-based employee compensation plans.
Based on this review and with input from its independent compensation consultant, the Compensation Committee concluded that the risks arising from the Company’s compensation programs, policies and practices, for both our executive officers and our other employees, are not reasonably likely to have a material adverse effect on Halozyme.

Other Compensation Matters
Stock Ownership and Retention Guidelines
We maintain stock ownership guidelines for our executive officers which stipulate that the CEO is required to own shares of Halozyme common stock with value equal to no less than six times the CEO’s current base salary and that all other executive officers are required to own shares of Halozyme common stock with value equal to no less than two times the officer’s current base salary. Certain other officers designated by the Compensation Committee are expected to own shares of Halozyme common stock with value no less than one times the officer’s current base salary. Each executive officer is expected to comply with the guidelines within five years of appointment as an executive officer, and has three years to comply with any incremental ownership required as a result of a promotion or other increase in applicable ownership multiple. Share ownership that counts for purposes of satisfying the applicable guideline level of ownership includes fully-owned shares (including shares held in trust and by immediate family members), vested but deferred shares, shares held in retirement accounts, and unvested stock units that are subject to time-based vesting only. Stock units subject to unsatisfied performance-based vesting conditions and unexercised stock options are not counted when evaluating compliance. Each executive officer is required to: (i) hold at least 50% of all net shares (after shares withheld or sold to pay tax obligations) of RSUs and PSUs that vest; and (ii) hold at least 50% of the underlying net gain (i.e., not including shares sold to pay the exercise price or to satisfy tax obligations) in shares of the Company’s common stock as a result of stock option exercises, until the executive officer comes into compliance with the stock ownership guidelines. The Compensation Committee annually reviews the progress executive officers are making toward achieving compliance with these guidelines and has determined that all of our NEOs have achieved their specific ownership levels as of February 1, 2025.
Equity Award Grant Practices
The Compensation Committee’s practice is to grant annual equity awards to executive officers at its first meeting in February each year, which is generally scheduled well in advance. Additionally, the Compensation Committee retains discretion to grant other equity awards from time to time when and as Compensation Committee may determine to be appropriate.
However, the timing of the grant of a Company equity award may be changed to satisfy the Company’s policy on the timing of equity award grants. The Company’s policy on the timing of equity award grants generally provides that if the Company files its Annual Report on Form 10-K, a Quarterly Report on Form 10-Q, or a Current Report on Form 8-K that contains information that would (but for such public disclosure) be material nonpublic information in respect of the Company with the Securities and Exchange Commission (any such filing by the Company with the Securities and Exchange Commission, a “Disclosure Event”) on, or on the business day immediately preceding, the intended date of grant of an equity award, the date of grant of such award will (unless otherwise provided by the Compensation Committee) be the second full trading day following the Disclosure Event. In addition, the policy generally provides that if, on the date of grant of an equity award, the Compensation Committee believes that the Company will have a Disclosure Event within the following four full business days, the date of grant of the award will (unless otherwise provided by the Compensation Committee) occur on the second full trading day following the Disclosure Event. Any equity awards approved pursuant to any delegated authority to approve equity award grants and other than by the Compensation Committee are generally subject to these same timing provisions. Equity awards granted to members of the Board of Directors in accordance with our non-employee director compensation program are not subject to these timing provisions.
The release of material nonpublic information is not taken into account in determining the timing and terms of equity award grants (other than, as to the timing of such awards, to satisfy the equity award grant timing policy discussed above), and the Company does not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation.
Change in Control Agreements
We have entered into Change in Control Agreements with our executive officers. We believe that the occurrence or potential occurrence of a change in control transaction creates uncertainty regarding the continued employment of our executive officers. This uncertainty results from the fact that many change in control transactions are common in our industry and often result in significant organizational changes, particularly at the senior executive level. We provide additional severance protections under the Change in Control Agreements to help ensure that executives can objectively evaluate change in control transactions that may be in the best interest of stockholders despite the potential negative consequences such transactions may have on them personally and to encourage executives to remain employed with the Company during an important time when their prospects for continued employment following the transaction are often uncertain.
Non-Change in Control Severance Policy
The Compensation Committee has approved a Company-wide severance policy, outside of a change in control context, that is also applicable to our executive officers. We believe that such severance protections are only appropriate in the event an executive is involuntarily terminated without cause and that these severance benefits are appropriate in light of severance protections available to executives at our peer group companies, and are an important component of each executive’s overall compensation as they help us to attract and retain our key executives who could have other job alternatives that may appear to them to be more attractive absent these
35

protections. Despite the establishment of the severance policy, however, the Board of Directors or Compensation Committee retains the right to amend, alter or terminate the severance policy at any time.
Incentive Compensation Recoupment (“Clawback Policy”)
In accordance with SEC and NASDAQ requirements, the Board has adopted an executive compensation recovery policy regarding the adjustment or recovery of certain incentive awards or payments made to current or former executive officers in the event that we are required to prepare an accounting restatement due to material noncompliance with any financial reporting requirement under the securities laws. In general, the policy provides that, unless an exception applies, we will seek to recover compensation that is awarded to an executive officer based on the Company’s attainment of a financial metric during the three-year period prior to the fiscal year in which the restatement occurs, to the extent such compensation exceeds the amount that would have been awarded based on the restated financial results.
Hedging and Pledging Restrictions
The Company’s Insider Trading Policy prohibits the pledging of Company securities as collateral and entering into transactions to hedge the value of Company securities owned by executives subject to the policy. Under the policy all directors and employees (including officers), or their designees, are prohibited from purchasing financial instruments (including prepaid variable forward contracts, equity swaps, collars and exchange funds) or otherwise engage in transactions, that hedge or offset, or are designed to hedge or offset, any decrease in the market value of Halozyme’s equity securities that are either (i) granted to the employee or director by Halozyme as part of the compensation of the employee or director or (ii) held, directly or indirectly, by the employee or director.
Tax Deductibility of Executive Compensation
Section 162(m) of the Internal Revenue Code generally disallows a tax deduction to public companies for compensation in excess of $1 million paid to a company’s chief executive officer and certain current and former executive officers. As a result, we expect that compensation paid per year to our NEOs and certain former executive officers in excess of $1 million generally will not be deductible, subject to limited exceptions. The Compensation Committee generally seeks to preserve tax deductions for executive compensation where available but may make compensation decisions based on other factors when it believes doing so is in the best interest of the Company and its stockholders.
Compensation Committee Report
We, the Compensation Committee of the Board of Directors of Halozyme Therapeutics, Inc., have reviewed and discussed the Compensation Discussion and Analysis contained in this Proxy Statement with management. Based on such review and discussion, we have recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement.

(1)This column represents the grant date fair value of stock awards granted to the NEOs in fiscal years 2024, 2023 and 2022, in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 718. Pursuant to SEC rules, the amounts shown exclude the impact of estimated forfeiture related to service-based vesting conditions. For additional information on the valuation assumptions used by us in calculating these amounts refer to Note 9 of the Notes to Consolidated Financial Statements, filed as part of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 filed with the SEC on February 18, 2025. Stock awards granted to executive officers consist of RSUs and PSUs. A portion of the amounts reported in this column for each NEO for each fiscal year reflect the grant-date fair value of PSUs granted to the executives during that fiscal year. In accordance with applicable SEC rules, these amounts were determined based on the probable outcome (determined as of the date of grant of the awards) of the performance-based conditions applicable to the awards. For these purposes, the grant date fair value for the Deal/Nomination PSU awards granted to each of the NEOs was determined based on the “target” vesting level applicable to the award (which we considered to be the probable outcome as of the date of grant of the awards) and the grant date fair value for the Relative TSR PSU awards granted to each of the NEOs was determined based on a Monte Carlo simulation pricing model (which probability weights multiple potential outcomes) as of the date of grant of the awards. The significant assumptions used in the Monte Carlo simulation pricing model were as follows:

|  | 2024 |  | 2023 |  | 2022
Expected volatility |  | 40.08% |  | 39.38% |  | 40.52%
Risk-free interest rate |  | 4.28% |  | 4.27% |  | 1.71%
Expected dividend yield |  | — |  | — |  | —

(3)The amounts reported in the Summary Compensation Table for stock awards and option awards may not represent the amounts that the NEOs will actually realize from the awards. Whether, and to what extent, an NEO realizes value will depend on stock price fluctuations and the NEO’s continued employment. To see the exact share amounts and the value of awards made to the NEOs in fiscal 2024, see the 2024 Grants of Plan-Based Awards table below. Additional information on all outstanding awards is reflected in the Outstanding Equity Awards at December 31, 2024 table.
(4)Performance-based bonuses are generally paid pursuant to our annual incentive plans and reported as Non-Equity Incentive Plan Compensation. The performance-based bonuses represent amounts earned during each respective fiscal year based on applicable performance levels for such fiscal year, regardless of whether part or all of such amounts were paid in a subsequent fiscal year.
(5)The table below lists the amounts set forth in this column which consist of other compensation including (i) Company contributions to Halozyme Therapeutics, Inc. 401(k) plan, and (ii) Company payments for group term insurance premiums.

Potential Payments Upon Termination or Change in Control
This section describes the benefits that may be provided to our NEOs upon certain terminations of their employment with the Company.
Termination Prior to Change in Control
Under our severance policy, if an executive officer’s employment is terminated by the Company without cause, the executive officer is entitled to receive cash severance equal to one times the executive officer’s then-current annual base salary (in the case of the CEO, one and one-half times the sum of (a) the CEO’s then-current base salary plus (b) the CEO’s target annual cash incentive amount), plus a pro-rated portion of the executive’s target annual cash incentive for the year of termination. Cash payments under the severance policy will normally be made in a lump sum payment, and will be conditioned upon the receipt of a release of claims from the executive officer. In addition to cash severance payments, the Company will also pay certain costs for the executive to continue healthcare coverage over the applicable severance period, and the executive’s vested options will remain exercisable for one year following the termination date (or, if earlier, until the expiration date of the option).
The PSU awards granted to our NEOs provide that if the executive’s employment is terminated by the Company without cause or by the executive for good reason and the executive provides a release of claims, any PSUs credited based on performance during a performance period that has already been completed will fully vest on the executive’s termination, and PSUs subject to a performance period that has not yet been completed will remain outstanding and eligible to vest based on performance during that period, subject to pro-ration to reflect the executive’s employment during the performance period. If the executive’s employment terminates due to the executive’s death or disability, any PSUs credited based on performance during a performance period that has already been completed will fully vest on the executive’s termination, and the target number of PSUs for the next performance period scheduled to be completed after the termination date will vest pro-rata based on the executive’s employment during that performance period.
The table below presents the benefits that would be provided to each of the NEOs assuming the NEO was terminated by us without cause (prior to a change in control of the Company) on December 31, 2024 and executed a release of claims in a form satisfactory to the Company:
2024 Potential Payments Upon Termination Without Cause Prior to Change in Control

Name |  | Lump Sum Severance Payment ($) |  | Post- Termination Healthcare ($) |  | Equity Awards ($) (1) |  | Total
Helen I. Torley |  | 2,304,000 |  |  | 29,939 |  |  | 10,641,982 |  |  | 12,975,921 |
Nicole LaBrosse |  | 852,282 |  |  | 34,651 |  |  | 2,925,496 |  |  | 3,812,429 |
Mark Snyder |  | 868,500 |  |  | 42,570 |  |  | 2,968,668 |  |  | 3,879,738 |
Michael J. LaBarre |  | 834,300 |  |  | 1,395 |  |  | 2,519,637 |  |  | 3,355,332 |

________________
(1)Amounts shown in this column reflect the market value of unvested PSUs that would have accelerated if the NEO was terminated without cause (or resigned for good reason) as described above on December 31, 2024. Values were derived using the closing trading price of our common stock on NASDAQ on December 31, 2024, the last trading date in fiscal year 2024, of $47.81. The number of accelerated PSUs for performance periods ending on or before December 31, 2024 was determined based on our actual performance through the end of the applicable performance period. We did not include any amount for the PSUs allocated to performance periods ending after December 31, 2024 because the number of PSUs that will vest with respect to those periods is not known as it will depend on our future performance (the maximum value of those PSUs at December 31, 2024 was $1,471,145 for Dr. Torley, $415,278 for Ms. LaBrosse, $411,264 for Mr. Snyder, and $309,439 for Mr. LaBarre. These amounts were calculated solely for purposes of this disclosure, and there can be no assurance that the value actually realized by the executive for these awards (if any) will be equal to the value shown in this column.
43

The table below presents the benefits that would be provided to each of the NEOs assuming the NEO’s employment terminated due to death or disability (prior to a change in control of the Company) on December 31, 2024:
2024 Potential Payments Upon Termination Due to Death/Disability Prior to Change in Control

Name |  | Equity Awards ($) (1)
Helen I. Torley |  | 11,536,006 |
Nicole LaBrosse |  | 3,173,268 |
Mark Snyder |  | 3,208,991 |
Michael J. LaBarre |  | 2,707,320 |

________________
(1)Amounts shown in this column reflect the spread value of unvested equity awards that would have accelerated if the NEO’s employment terminated due to death or disability on December 31, 2024. Please see the note to the 2024 Potential Payments Upon Termination Without Cause Prior to Change in Control table above for the calculation of these amounts. The number of accelerated PSUs for performance periods ending on or before December 31, 2024 was determined based on our actual performance through the end of the applicable performance period, and the number of accelerated PSUs for the performance period ending December 31, 2025 represents the target number of PSUs allocated to such period (pro-rated for the executive’s period of employment). These amounts were calculated solely for purposes of this disclosure, and there can be no assurance that the value actually realized by the executive for these awards (if any) will be equal to the value shown in this column.
Change in Control
We have entered into Change in Control Agreements with each of our executive officers. The Change in Control Agreements provide for cash severance, continued healthcare coverage and accelerated vesting of equity awards if the executive is terminated without cause, resigns for good reason, or is terminated due to death or disability (as such terms are defined in the Change in Control Agreements), in each case on or within 12 months following a change in control transaction. The cash severance, to be made in a lump sum payment, will equal: a multiple (two times for the CEO and one-and-one-half times for the other executive officers) of the sum of (i) the executive’s then-current annual base salary; and (ii) the amount of the executive’s target annual cash incentive opportunity (based on the target percentage of annual base salary) in respect of the year the termination of employment occurs. The Company will also make a cash lump sum payment intended to provide the executive officer sufficient amounts to pay expected heath care premiums under the Company’s group health plans for 18 months after termination of employment (24 months in the case of the CEO). In addition, the Change in Control Agreement provides that the executive’s outstanding and unvested equity awards granted by the Company will be fully vested upon the executive’s termination (with equity awards that are subject to performance-based vesting to accelerate based on the greater of (x) the target performance level for the applicable portion of the award and (y) the actual performance level achieved for the applicable portion of the award through the executive’s termination date). However, the PSU awards granted to the NEOs provide that if a change in control occurs, any performance period then in progress will terminate and the number of PSUs to be credited under the award will be determined based on (i) as to the Relative TSR PSUs, performance through the change in control and (ii) as to the Deal/Nomination PSUs, the greater of performance through the change in control or the target performance level for the award. Such credited PSUs will remain subject to time-based vesting through the third anniversary of the grant date, subject to accelerated vesting if the credited PSUs are not assumed by the acquiring company or if within two years after the change in control the executive’s employment is terminated by the Company without cause, by the executive for good reason, or due to the executive’s death or disability. An executive officer will not be entitled to severance benefits under our severance policy described above if the executive is entitled to severance benefits under the executive’s Change in Control Agreement. The Change in Control Agreements also provide that if an executive officer’s severance benefits would be subject to the parachute payment taxes of Sections 280G and 4999 of the Internal Revenue Code of 1986, as amended, and a reduction in benefits to avoid such taxes would put the executive in a better after-tax position, then the executive’s benefits will be reduced to the extent necessary to avoid such taxes.
44

Assuming a change in control took place on December 31, 2024 and each of the NEOs was terminated without cause, resigned for good reason or was terminated due to death or disability in each case on December 31, 2024, the NEOs would have received the following benefits as a result of such terminations:
2024 Potential Payments Upon Change in Control Termination

Name |  |  | Equity Awards ($) (1) |  | Lump Sum Cash Severance ($) |  | Post- Termination Healthcare ($) |  | Total ($)
Helen I. Torley |  | 24,851,043 |  |  | 3,648,000 |  |  | 89,807 |  |  | 28,588,850 |
Nicole LaBrosse |  | 6,873,650 |  |  | 1,278,423 |  |  | 77,962 |  |  | 8,230,035 |
Mark Snyder |  | 7,970,244 |  |  | 1,302,750 |  |  | 95,791 |  |  | 9,368,785 |
Michael J. LaBarre |  | 5,891,211 |  |  | 1,251,450 |  |  | 3,142 |  |  | 7,145,803 |

________________
(1)Amounts shown in this column reflect the value of the unvested equity awards that would have accelerated if the NEO’s employment terminated in the circumstances described above on December 31, 2024 in connection with a change in control. Please see the note to the 2024 Potential Payments Upon Termination Without Cause Prior to Change in Control table above for the calculation of these amounts. The number of accelerated PSUs was determined based on our actual performance through December 31, 2024 (or, if greater, the target performance level in the case of Deal/Nomination PSUs). These amounts were calculated solely for purposes of this disclosure and there can be no assurance that the value actually realized by the executive for these awards (if any) will be equal to the value shown in this column.
CEO Pay Ratio
For 2024, Dr. Torley’s total compensation was $12,741,421, as shown in the Summary Compensation Table above. The total compensation for our median employee (excluding the CEO) in 2024 was $220,881. Therefore, Dr. Torley’s total compensation for 2024 was 58 times that of the median employee’s total compensation in 2024. The Company believes the pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records, as well as the methodology described below.
The compensation elements that were considered in the identification of the median employee were annualized base pay, target cash bonus opportunity and target long-term incentive award grant date fair value for 2023 for all employees, excluding the CEO, as of December 31, 2023. The total number of our employees as of December 31, 2023 (excluding the CEO) was 382. We used this population to determine the median employee. The total compensation for the median employee used in reporting the pay ratio in the preceding paragraph was calculated according to the requirements of the Summary Compensation Table.

(1)Helen I Torley was our CEO for each of the five years included in the table above. For 2020, our Non-PEO NEOs were Elaine D. Sun, Laurie D. Stelzer, Masaru Matsuda, and Michael J. LaBarre. For 2021, our Non-PEO NEOs were Elaine D. Sun, Masaru Matsuda, and Michael J. LaBarre. For 2022, our Non-PEO NEOs were Nicole LaBrosse, Elaine D. Sun, Mark Snyder, and Michael J. LaBarre. For 2023 and 2024, our Non-PEO NEOs were Nicole LaBrosse, Mark Snyder, and Michael J. LaBarre. Ms. Sun commenced employment with Halozyme on March 2, 2020 and separated employment from Halozyme on February 2, 2022. Mr. Matsuda separated employment from Halozyme on December 31, 2021. Ms. LaBrosse was appointed to Halozyme’s Chief Financial Officer on February 2, 2022 and Mr. Snyder commenced employment with Halozyme on January 3, 2022.
(2)See the Summary Compensation Table above for detail on the Summary Compensation Table total compensation for our CEO for fiscal year 2024, 2023 and 2022. The 2020 and 2021 total compensation for our CEO is disclosed in our proxy statement filed with the SEC in calendar years 2021 and 2022, respectively. The average compensation for the Non-PEO NEOs for 2024 was calculated in the Summary Compensation Table above. The average compensation for the Non-PEO NEOs for each of fiscal years 2023, 2022, 2021 and 2020 was calculated from the Summary Compensation Table as disclosed in our proxy statement filed with the SEC in the calendar year immediately following such fiscal year.
(3)For purposes of this table, the compensation actually paid (“Compensation Actually Paid”, or “CAP”) to each of our Named Executive Officers (including for purposes of this table, former named executive officers who are included in the Non-PEO NEO group for the applicable year) means the Named Executive Officer’s total compensation as reflected in the Summary Compensation Table for the applicable year less the grant date fair values of stock awards and option awards included in the “Stock Awards” and “Option Awards” columns of the Summary Compensation Table for the Named Executive Officer for the applicable year, and adjusted for the following with respect to Halozyme’s LTI awards granted to the Named Executive Officer:
•Plus the year-end value of awards granted in the covered fiscal year which were outstanding and unvested at the end of the covered fiscal year,
•Plus/(less) the change in value as of the end of the covered fiscal year as compared to the end of the prior fiscal year for awards which were granted in prior years and were outstanding and unvested at the end of the covered fiscal year,
•Plus the vesting date value of awards which were granted and vested during the same covered fiscal year,
•Plus/(less) the change in value as of the vesting date as compared to the end of the prior fiscal year for awards which were granted in prior years and vested in the covered fiscal year,
46

•Less, as to any awards which were granted in prior fiscal years and were forfeited during the covered fiscal year, the value of such awards as of the end of the prior fiscal year,
•Plus the dollar value of any dividends or other earnings paid during the covered fiscal year on outstanding and unvested awards (no dividends or other earnings were paid by Halozyme on any Named Executive Officer’s Halozyme LTI awards during the fiscal years covered by the table),
•Plus, as to an award that is materially modified during the covered fiscal year, the amount by which the value of the award as of the date of the modification exceeds the value of the original award on the modification date (none of the Halozyme LTI awards held by the Named Executive Officers were materially modified during the fiscal years covered by the table).
In making each of these adjustments, the “value” of an award is the fair value of the award on the applicable date determined in accordance with FASB’s ASC Topic 718 using the valuation assumptions we then use to calculate the fair value of our equity awards. For more information on the valuation of our equity awards, please see the notes to our financial statements that appear in our Annual Report on Form 10-K each year and the footnotes to the Summary Compensation Table that appears in our annual proxy statement.
The table reflects the CAP (determined as noted above) for our CEO and, for our Non-PEO NEOs, the average of the CAPs determined for the Non-PEO NEOs.
The following table provides a reconciliation of the Summary Compensation Table Total to Compensation Actually Paid for our CEO for the fiscal year 2024.

(4)Total Shareholder Return represents the return on a fixed investment of $100 in Halozyme’s stock for the period beginning on the last trading day of 2019 through the end of the applicable fiscal year. Peer Group Total Shareholder Return represents the return on a fixed investment of $100 in the NASDAQ Biotechnology Index for the period beginning on the last trading day of 2019 through the end of the applicable fiscal year, and is calculated assuming the reinvestment of dividends. The following chart illustrates the CAP for our CEO and the average CAP for our Non-PEO NEOs for each of the last five years against our total shareholder return and the total shareholder return for the NASDAQ Biotechnology Index (each calculated as described above) over that period of time.

(5)This column shows Halozyme’s net income for each fiscal year covered by the table. The following chart illustrates the CAP for our CEO and the average CAP for our Non-PEO NEOs for each of the last five years against our net income for each of those years.
(6)This column shows Halozyme’s revenue for each fiscal year covered by the table. We consider revenue to be a the most important financial performance metric in our 2024 executive compensation program because it is used in determining each of our NEO’s annual 2024 cash incentive. The following chart illustrates the CAP for our CEO and the average CAP for our Non-PEO NEOs for each of the last five years against our revenue for each of those years.
49

The following is an unranked list of the Halozyme financial performance measures we consider most important in linking the compensation actually paid to our Named Executive Officers for 2024 with Halozyme performance.
•Revenue (as used in our 2024 EBP)
•Adjusted EBITDA (as used in our 2024 EBP)
•Stock Price (including relative TSR, as used in our PSUs awarded in 2021, 2022, 2023 and 2024 and as described in the Compensation Discussion and Analysis above)
In addition to the financial performance measures listed above, we view our stock price, upon which the value of all of our equity awards is dependent, as a key performance-based component of our executive compensation program in order to further align the interests of our senior management with the interests of our stockholders.

Directors’ Compensation
The compensation program for our non-employee directors is as follows:
(1) Annual award - Immediately following each Annual Meeting, each non-employee director then in office automatically receives (i) an annual restricted stock unit grant having a value of approximately $250,000 (with the number of shares of Company common stock subject to the award equal to $250,000 divided by the closing trading price of the Company’s common stock on NASDAQ on the date of grant, with any fraction rounded up to the nearest whole share) and (ii) an annual stock option grant with a value of approximately $150,000 (with the number of shares of Company common stock subject to the award equal to $150,000 divided by the per-share value of Company stock options determined based on the valuation method and assumptions then generally used by the Company in valuing its options for financial statement purposes). Subject to acceleration in the event of a change of control of the Company, these annual awards will vest in full on the earlier of (i) the first anniversary of the date of grant or (ii) the date of the next Annual Meeting following the date of the annual grants. All awards granted after our 2021 annual meeting are granted under our 2021 Stock Plan. Vested options granted to our non-employee directors (including the initial option grants described below) generally remain exercisable for three years following the termination of the director’s service (subject to earlier termination at the end of the term of the option or in connection with a change in control).
(2) Initial award - each non-employee director receives an initial restricted stock unit grant and stock option grant upon joining the Board (with the number of shares of Company common stock subject to each award determined in the same manner as for the annual award grants described above); provided that, the grant date value of each award for a director first elected or appointed between Annual Meetings shall be prorated based on the number of full quarters the individual is scheduled to serve as a non-employee director from the date of election or appointment until the next Annual Meeting of the Stockholders such that the recipient will receive a grant of restricted stock units valued at $187,500 and a stock option grant valued at $112,500 for a period of service exceeding three quarters, a grant of restricted stock units valued at $125,000 and a stock option grant valued at $75,000 for a period of service exceeding two-quarters (but no more than three quarters), a grant of restricted stock units valued at $62,500 and a stock option grant valued at $37,500 for a period of service exceeding one quarter (but no more than two quarters), and no award for a period of service of one quarter or less. Subject to acceleration in the event of a change of control of the Company, these initial grants will vest upon the date of the next Annual Meeting following the date of grant.
Our non-employee directors also receive an annual retainer of $50,000 for service on the Board (provided that our Chair of the Board of Directors receives an annual retainer of $125,000), as well as an additional annual retainer for service on any committee of the Board. Non-employee directors who serve on the Audit Committee receive an annual retainer of $15,000, provided that the Chair of that committee receives an annual retainer of $30,000. Non-employee directors who serve on the Compensation Committee receive an annual retainer of $10,000, provided that the Chair of that committee receives an annual retainer of $20,000. Non-employee directors who serve on the Nominating and Corporate Governance Committee receive an annual retainer of $5,000, provided that the Chair of that committee receives an annual retainer of $10,000. Employee directors (including our CEO) do not receive any compensation for service on the Board of Directors.
We also maintain stock ownership guidelines for our non-employee directors which stipulate that each non-employee director is expected to own shares of Halozyme common stock with value equal to no less than five times the non-employee director’s base annual retainer for service on the Board of Directors. Each non-employee director is expected to comply with the guidelines within five years of election or appointment to the Board of Directors. Share ownership that counts for purposes of satisfying the applicable guideline level of ownership is the same as under our executive stock ownership guidelines, as described in the CD&A above. The same retention requirements apply to a non-employee director whose level of stock ownership does not satisfy the applicable guideline level of ownership as under our executive stock ownership guidelines, as described in the CD&A above.
The Company also maintains the Halozyme Nonqualified Deferred Compensation Plan (the “Cash Deferral Plan”) and the Halozyme Therapeutics, Inc. Directors Deferred Equity Compensation Plan (the “Equity Deferral Plan”). Under the Cash Deferral Plan, a non-employee director may elect to defer payment of all or a portion of the director’s annual cash compensation, deferrals are credited with earnings or losses based on investment fund elections made by the director, and the deferred amounts (as adjusted for such earnings or losses) will be paid to the director (in a lump sum or annual installments over up to five years, as elected by the director) when the director no longer serves on the Board of Directors or an earlier distribution date elected by the director in accordance with the plan. Under the Equity Deferral Plan, a non-employee director may elect (1) to convert all or a portion of the director’s annual cash compensation into Company restricted stock units awarded under our 2021 Stock Plan and/or (2) to defer the payment of the director’s annual restricted stock unit award from the Company. If a non-employee director elects to convert all or a portion of the director’s cash retainers into restricted stock units, the director will be credited with additional restricted stock units on the date the retainers would have otherwise been paid to the director equal to (1) the amount being deferred to the Equity Deferral Plan that would have otherwise been paid to the director
52

on that date, divided by (2) the average closing price for a share of Company common stock over the period of ten consecutive trading days ending with the last trading day prior to the crediting date. Deferred restricted stock units will be credited with dividend equivalents to preserve the value of the awards if/when the Company were to ever pay a dividend. A non-employee director’s deferred restricted stock units will be paid in Company common stock (in a lump sum or annual installments over up to five years as elected by the director) when the director no longer serves on the Board of Directors or, if earlier, upon a change in control of the Company.

STOCKHOLDER PROPOSALS TO BE PRESENTED AT NEXT ANNUAL MEETING
Stockholder proposals, including nominations for candidates for membership on our Board of Directors, may be included in our proxy materials for an Annual Meeting so long as they are provided to us on a timely basis and satisfy the other conditions set forth in applicable SEC rules. For a stockholder proposal to be included in our proxy materials for the 2026 Annual Meeting, the proposal must be received at our principal executive offices, addressed to the Secretary, not later than November 18, 2025.
Stockholder business that is not intended for inclusion in our proxy materials may be brought before the 2026 Annual Meeting so long as we receive notice of the proposal as specified by our Bylaws, addressed to the Secretary at our principal executive offices, not later than November 18, 2025, in accordance with the specific procedural requirements in our Bylaws. If the Secretary fails to receive notice of the proposal within such timeframe, any such proposal will be considered untimely. Failure to comply with our Bylaw procedures and deadlines may preclude presentation of the proposal at our 2026 Annual Meeting.
In addition to satisfying the requirements of our Bylaws, including the earlier notice deadlines set forth above and therein, to comply with universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than our nominees must also provide notice that sets forth the information required by Rule 14a-19 of the Securities Exchange Act of 1934, as amended, no later than March 2, 2026.
TRANSACTION OF OTHER BUSINESS
At the date of this Proxy Statement, the Board of Directors knows of no other business that will be conducted at the 2025 Annual Meeting other than as described in this Proxy Statement. If any other matter or matters are properly brought before the meeting, or any adjournment or postponement of the meeting, it is the intention of the persons named in the accompanying form of proxy to vote the proxy on such matters in accordance with their best judgment.

DELIVERY OF PROXY MATERIALS AND ANNUAL REPORTS
We may satisfy SEC’s rules regarding delivery of proxy statements and annual reports by delivering a Notice of Internet Availability of Proxy Materials to an address shared by two or more stockholders. This process is known as “householding.” This delivery method can result in meaningful cost savings for us. In order to take advantage of this opportunity, we have delivered only one Notice of Internet Availability of Proxy Materials to multiple stockholders who share an address, unless contrary instructions were received prior to the mailing date. Accordingly, for many stockholders who hold their shares through a bank, brokerage firm or other holder of record (i.e., in “street name”) and share a single address, only one Notice of Internet Availability of Proxy Materials is being delivered to that address unless contrary instructions from any stockholder at that address were received.
We undertake to deliver promptly upon written or oral request a separate copy of Notice of the Internet Availability of Proxy Materials, proxy statement and/or annual report, as requested, to a stockholder at a shared address to which a single copy of these documents was delivered. If you hold stock as a record stockholder and prefer to receive separate copies of a proxy statement or annual report either now or in the future, please contact our Secretary at 12390 El Camino Real, San Diego, California 92130, or by telephone at (858) 794-8889. If your stock is held by a brokerage firm or bank and you prefer to receive separate copies of a proxy statement or annual report either now or in the future, please contact your brokerage or bank. The voting instruction sent to a street-name stockholder should provide information on how to request (1) householding of future company materials or (2) separate materials if only one set of documents is being sent to a household. If it does not, a stockholder who would like to make one of these requests should contact us as indicated above.
By order of the Board of Directors,
Mark Snyder
Senior Vice President, General Counsel,
and Corporate Secretary
