Dear Shareholders,

Waters is entering a new era of growth. Since beginning our transformation journey in 2020, our dedicated executive team has successfully regained commercial momentum, revitalized our portfolio, and expanded into rapidly growing adjacent markets. We finished 2024 in a position of strength with greater scale in our adjacencies and resilience across our business.

Over the past year, the Board maintained its prioritization of strong corporate governance practices and active director refreshment to ensure we are equipped with the set of skills and expertise needed to effectively oversee Waters’ ambitious strategy. Our highly qualified Board is composed of 10 directors, all of whom contribute skills critical to overseeing Waters’ strategy, including expertise in global markets, science and technology, manufacturing, strategic planning, and mergers and acquisitions. Further to this goal, in August 2024, we welcomed Heather Knight as our newest independent director. She brings extensive expertise in the pharmaceutical and medical device industries, along with innovation-focused strategic insights that enhance discussions on strategies to accelerate Waters’ operational and financial performance.

As we look to 2025, the Board remains confident in the deep bench of talent on our executive team and their ability to carry forward our leadership position in downstream, high-volume life sciences applications. The Board and management team will continue to prioritize effective oversight of our most critical asset: our people. One of Waters’ greatest strengths is the tremendous dedication of our 7,600 global employees, who closely collaborate with our customers to solve their greatest scientific challenges.

The Board is proud to have been named the 2024 “Public Company Board of the Year” by the National Association of Corporate Directors (NACD) New England Chapter.

On behalf of the full Board, thank you for your investment and engagement with Waters. We value the perspectives and feedback of all of our shareholders as we pursue our goal of creating sustainable shareholder growth. We respectfully ask for your support on the matters presented for vote in this proxy statement.

Sincerely,
Dr. Flemming Ornskov, M.D., M.P.H. Chair of the Board of Waters Corporation

Dear Shareholders,

Throughout 2024, Waters has remained focused on operational excellence, capitalizing on the success of our new product launches and deepening our relationships with customers globally. Thank you for your continued support. I would also like to extend my sincere appreciation to our team for their commitment, which has been fundamental in achieving this year’s great progress.

In the second half of 2024, we returned to growth across all our end-markets, successfully navigating significant market headwinds we had experienced earlier in the year. Although revenues were flat for 2024, we achieved year-over-year GAAP and adjusted operating income margin expansion, closing the year at 27.9% as reported and 31.0% on an adjusted basis, even after absorbing significant foreign exchange impacts. 2024 also marks the fourth consecutive year in which we have delivered top-tier total shareholder returns, putting us again at the top of the Life Science tools peer group.

At Waters, we continue to be driven by our purpose to accelerate the benefits of pioneering science. We collaborate with our customers to address complex challenges – such as bringing life-saving therapies to market, detecting diseases early, keeping the food and water we consume pure, and ensuring batteries are safe to use. I am incredibly proud of what we are building together.

Over the past four years, we have successfully executed a transformation that has enabled us to regain our commercial momentum, revitalize our innovation, and enter fast-growing adjacencies. In 2024, we made significant strides in each area. As we regained our commercial momentum our strategic initiatives enabled us to:

| • |  | Establish a strong cadence of instrument replacement, with only 15% of aged instruments remaining in the original data set;

| • |  | Increase our service attachment rate to over 50%, with our service team achieving top ranking by our customers, with industry-leading net promoter scores according to the Technology & Services Industry Association;

| • |  | Drive eCommerce adoption, with over 40% of chemistry revenue for the year generated online; and

| • |  | Increase contract organizations, which represented 25% of pharmaceutical revenue for the year.

We revitalized our portfolio through several innovative product launches that play a unique role in solving customers’ unmet needs and focus on reducing human error, simplifying workflows, and improving product sustainability. A few highlights include Alliance iS Bio HPLC System, for smarter, more capable liquid chromatography separation; XevoTM MRT Mass Spectrometer, with its market-leading sensitivity and sustainable design; and our newer column launches, which are aimed at separating larger, more complex molecules like biologics and novel modalities

Finally, we continued to allocate resources to enter faster-growing adjacencies. We invested in areas such as bioseparations, bioanalytical characterization, took LC-MS into specialty diagnostics, and introduced our thermal and mechanical analysis portfolio to battery testing.

We are now entering a new phase of growth in 2025, building on our transformation, as we:

| • |  | Embed excellence in execution

| • |  | Continue to deliver pioneering innovation

| • |  | Scale up in high-growth areas

We are well positioned to capitalize on the emerging opportunities ahead to drive sustained, long-term growth while continuing to collaborate with our customers to accelerate the benefits of pioneering science.

Thank you for your trust and continued investment in Waters.

Sincerely, Udit
Udit Batra, Ph.D. President and Chief Executive Officer

Required Vote and Recommendation of the Board of Directors

A nominee for director shall be elected to the Board by a majority vote (i.e., the votes cast for such nominee must exceed the votes cast against such nominee) at any meeting of shareholders for the election of directors at which a quorum is present, except that directors will be elected by a plurality of the votes cast in a contested election. A “contested election” is one in which the Secretary of the Company receives a notice that a shareholder intends to nominate one or more persons for election to the Board in purported compliance with the Bylaws and such nomination notice has not been subsequently withdrawn or on prior to the tenth day before the notice of meeting is first mailed. If an incumbent director fails to be re-elected by a majority vote when such a vote is required and offers to resign, and if that resignation is not accepted by the Board, such director shall continue to serve until the next annual meeting and until his or her successor is duly elected, or his or her earlier resignation or removal. If an incumbent director’s resignation is accepted by the Board, or if a nominee for director is not elected and the nominee is not an incumbent director, then the Board, in its sole discretion, may fill any resulting vacancy or may decrease the size of the Board. “Abstentions” and shares with respect to which a broker or representative does not vote on a particular matter because it does not have discretionary voting authority on that matter (so-called “broker non-votes”) are counted as present for the purpose of determining whether a quorum is present. Abstentions and broker non-votes will not be treated as votes cast with respect to any nominee and therefore will not have an effect on the determination of whether a nominee has been elected.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” EACH NOMINEE FOR DIRECTOR SET FORTH ABOVE.

CORPORATE GOVERNANCE

HOW WE ARE SELECTED AND ELECTED

Ten Directors are to be elected at the Annual Meeting, each to hold office until his or her successor is elected and qualified or until his or her earlier resignation, death or removal. It is intended that the Proxies in the form included with this Proxy Statement will be voted for the nominees set forth above unless shareholders specify to the contrary in their Proxies or specifically abstain from voting on this matter.

Majority Voting

The Company’s bylaws (the “Bylaws”) provide for majority voting for Directors in uncontested elections. A further description of the Company’s majority voting provisions can be found above.

Board Candidates

The Nominating and Corporate Governance Committee, together with the Board, is responsible for assessing the appropriate skills, attributes, experiences, and diversity of background that we seek in Board members in the context of the existing composition of the Board.

The Nominating and Corporate Governance Committee believes that candidates for service as a Director of the Company should meet certain minimum qualifications. The Company’s Corporate Governance Guidelines (the “Guidelines”) and Nominating and Corporate Governance Committee’s charter clarify that when assessing candidates for Director, the Nominating and Corporate Governance Committee considers candidates’ skills, experience, and diversity (such as, and including but not limited to, diversity of skills, experiences, and backgrounds), and seeks individuals who are highly accomplished in their respective fields, with superior educational and professional credentials. The Nominating and Corporate Governance Committee strives to maintain an appropriate balance of tenure, skills, and experience, with our average director tenure being approximately five years. The Board does not maintain term limits, and, in 2024, the Board amended the Guidelines to remove the mandatory retirement age for directors, as the Board believes that continuity of service can provide stability and valuable insight. Candidates should also satisfy the Company’s independence criteria, which are part of its Guidelines and summarized below, and follow the applicable listing standards of the New York Stock Exchange (the “NYSE”).

The Nominating and Corporate Governance Committee also seeks to ensure proper engagement from each of the Directors and effective functioning of the Board. The Company’s Guidelines provide that a Director may serve on other public company boards so long as such Director is able to devote the time necessary to properly discharge his or her duties and responsibilities to the Board, except that no director may serve simultaneously on the audit committees of more than three public companies (including the Company) unless the Board first has determined that such simultaneous service would not impair the ability of such member to serve on the Board’s Audit & Finance Committee. The Company does not impose specific thresholds on the number of other public company boards its Directors may serve on as the Company believes such thresholds are arbitrary and do not permit the Board to review the facts and circumstances involved in a particular Director’s decision to serve on the board of more than one public company. As part of the Nominating and Corporate Governance Committee’s discussions about individuals to recommend for nomination to serve as directors of the Company and to which committees those directors will be assigned, the Nominating and Corporate Governance Committee considers whether an individual’s other commitments are likely to interfere with such individual’s ability to properly discharge his or her duties to the Board and any Committees on which he or she may serve. Such evaluation is based on the facts and circumstances relating to each individual’s commitments, whether known to the Nominating and Governance Committee through discussion with the individual or other directors who have experienced similar obligations, or through such individual’s historic performance as a director, in the case of individuals who are then serving as a director of the Company.

The Company has a process for identifying and selecting candidates for Board membership. Initially, the Chair, the President and Chief Executive Officer (“CEO”), the Nominating and Corporate Governance Committee, or other Board members identify a need either to expand the Board with a new member possessing certain

16

##### Table of Contents

specific characteristics or to fill a vacancy on the Board. A search is then undertaken by the Nominating and Corporate Governance Committee, working with recommendations and input from Board members, members of senior management, professional contacts, external advisors, nominations by shareholders, and/or the retention of a professional search firm, if necessary. Any shareholder wishing to propose a nominee should follow the process described in the Bylaws to submit the candidate’s name and appropriate biographical information to the Company, c/o Secretary, at 34 Maple Street, Milford, MA 01757. In addition to satisfying the requirements of the Bylaws, to comply with the SEC’s universal proxy rules, any shareholder intending to solicit proxies in support of a nominee other than the Company’s nominees must also comply with the additional requirements of Rule 14a-19 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

An initial slate of candidates is identified that will satisfy the criteria for Board membership and is presented to the Nominating and Corporate Governance Committee for review. Upon review by the Nominating and Corporate Governance Committee, a series of interviews of one or more candidates is conducted by the Chair, the President and CEO, and at least one member of the Nominating and Corporate Governance Committee. During this process, the full Board is informally apprised of the status of the search and its input is solicited.

Upon identification of a final candidate, the entire Nominating and Corporate Governance Committee will meet to consider the credentials of the candidate and thereafter, if approved, will submit the candidate for approval by the full Board.

Proxy Access

The Board has adopted a proxy access bylaw provision that allows eligible shareholders or groups of up to 20 shareholders who have held at least 3% of our common stock continuously for three years to nominate up to two individuals or 20% of the Board, whichever is greater, for election at our annual shareholder meeting, and to have those individuals included in our proxy materials for that meeting.

Board/Director Independence

The Company’s Guidelines include the Company’s categorical standards of independence, which our Board approved, and the Guidelines provide criteria adopted by the Board to assist it in making determinations regarding the independence of its members. Those criteria, summarized below, are consistent with the NYSE listing standards regarding director independence. To be considered independent, the Board must determine that a director does not have a material relationship, directly or indirectly, with the Company. A director will not be considered independent if:

| • |  | he or she or an immediate family member is, or has been within the last three years, an executive officer of the Company;

| • |  | he or she or an immediate family member is a current partner of an internal or external auditor of the Company or has been within the last three years a partner or employee of an internal or external auditor of the Company who personally worked on the Company’s audit;

| • |  | he or she or an immediate family member is, or has been within the last three years, an executive officer of a public company where any of the Company’s present executive officers at the same time serves or served on the compensation committee of that company’s board;

| • |  | he or she or an immediate family member has received more than $120,000 in direct compensation from the Company (other than fees for service as a director or pension or deferred compensation for prior service, provided that such compensation is not contingent in any way on continued service) during any twelve-month period within the past three years; or

| • |  | he or she is an employee, or an immediate family member is an executive officer, of a company that does business with the Company and the annual payments to or from the Company, in any of the last three fiscal years, exceeded the greater of $1 million or 2% of the other company’s annual gross revenues.

17

##### Table of Contents

In addition, a director will not be considered independent if he or she is an executive officer of a tax-exempt entity that receives contributions in any fiscal year from the Company exceeding the greater of $1 million or 2% of its gross revenues (excluding the Company’s matching of employee charitable contributions). A director also will not be considered independent if he or she is a current employee of an internal or external auditor of the Company.

The Board has determined that each Director, other than Dr. Batra, the Company’s President and CEO, has no material relationship with the Company and otherwise qualifies as “independent” under these criteria and the applicable listing standards of the New York Stock Exchange.

HOW WE ARE EVALUATED

The Nominating and Corporate Governance Committee conducts an annual evaluation of the Board and each of its committees. In December 2024, the evaluation, in the form of a questionnaire, was circulated to all members of the Board and each committee. The Company’s General Counsel received all of the questionnaires, compiled the results, and circulated them to the Board and each committee for discussion and analysis during January 2025. It is the intention of the Nominating and Corporate Governance Committee to continue to engage in this process annually.

HOW WE GOVERN AND ARE GOVERNED

At Waters, we believe that sound principles of corporate governance are essential to protecting Waters’ reputation, assets, investor confidence, customer loyalty, and sustainability. Our Guidelines can be found on our website at ir.waters.com/esg/governance-documents and are available in print upon written request to the Company, c/o Secretary, at 34 Maple Street, Milford, MA 01757.

We also believe in sound principles of board governance — how we govern ourselves sets the tone for how our company is governed more generally. Our board governance practices include:

✓ Proxy Access As described above, the Company enables eligible shareholders to nominate director candidates via our proxy access process as governed by our Bylaws.

✓ Majority Approval Required for Director Elections If an incumbent Director up for re-election at a meeting of shareholders fails to receive a majority of affirmative votes in an uncontested election, the Board will adhere to the director resignation process as provided in our Bylaws.

✓ Independent Board and Committees All Directors other than our President and CEO, and all members of the Audit & Finance Committee, the Compensation Committee, the Nominating and Corporate Governance Committee, and the Science and Technology Committee are independent.

✓ Engaged in Strategy Our Board is engaged in advising and overseeing the Company’s strategy and strategic priorities.

✓ Director Qualifications and Evaluations All of our independent Directors meet the candidate qualifications set forth in our Guidelines and as summarized in the above sections of this Proxy Statement: “— How We Are Selected and Elected — Board Candidates” and “— How We Are Selected and Elected — Board/Director Independence”.

✓ Regular Executive Sessions of Independent Directors Our independent Directors meet privately on a regular basis. Our Chair presides at such meetings.

✓ Stock Ownership Requirements We have robust stock ownership requirements for our Directors and executive officers.

✓ Enterprise Risk Management We have an enterprise risk management framework to identify, assess, manage, report, and monitor enterprise risk, including cybersecurity risk, and areas that may affect our ability to achieve our objectives.

18

##### Table of Contents

✓ Cybersecurity Our Audit & Finance Committee oversees our cybersecurity risk management and actively works with the Board and management to identify, assess, manage, report, and monitor such cybersecurity risks on at least a quarterly basis, and more frequently if necessary.

✓ Human Capital Management Our Board dedicates a meeting session to a review of talent, as well as matters related to succession planning.

✓ Director Orientation and Ongoing Director Education Our Board, with management support, hosts a director orientation program for new directors. The Board also administers a twice-yearly director education program, the topics for which are selected by the Board’s Nominating and Corporate Governance Committee.

✓ Board and Committee Oversight of ESG Our Board has delegated oversight of the Company’s environmental, sustainability and governance policies and practices to its Nominating and Corporate Governance Committee, which reports out to the Board at least annually on our efforts to leave the world better than we found it.

Shareholder Engagement

Our Board and management are committed to regular shareholder engagement and value constructive feedback to ensure alignment with shareholder interests on matters related to strategy, performance and results, corporate governance, sustainability, and executive compensation, among other topics. Our Investor Relations team regularly engages with shareholders on these topics, and that feedback is shared with management and the Board at least quarterly. Incorporating and addressing valuable feedback and insights from our shareholders is a key component in the deliberations and decision-making processes of the Board and management.

Say-on-Pay

Our shareholders vote annually on a non-binding, advisory basis, on the compensation of our executive officers, which we call our Say-on-Pay shareholder vote. The Company takes the support of our shareholders seriously and actively solicits feedback from our shareholders on our compensation programs. Shares voted in favor of our executive compensation program in fiscal year 2024 represented approximately 80% of votes cast.

Approximately 80% of stockholders voted in favor of our 2024 Say-on-Pay proposal |  | The Compensation Committee values the opinions of our shareholders and considers the outcome of our annual Say-on-Pay shareholder vote in determining the structure of our executive compensation program, as well as in making future compensation decisions.

Listening to Our Shareholders

Over the last several years, the Compensation Committee has made changes to our executive compensation program driven by changes in business and market practices, as well as shareholder feedback. A majority of our shareholders continue to have favorable views of our executive compensation program overall, including our emphasis on performance-based compensation and the strength of our performance goals. Our shareholders have provided constructive feedback to the Company in certain areas of our executive compensation program. In response to feedback requesting that a majority of our long-term incentive award consist of performance-based equity, we have rebalanced our mix to 55% PSUs, 30% stock options and 15% RSUs, commencing with fiscal year 2025. The Compensation Committee continues to believe that revenue and operating income are key drivers of our Company today and further that rTSR enhances our alignment with shareholders.

Related Party Transactions Policy
The Board has adopted a written Related Party Transactions Policy, which covers “Interested Transactions” between a “Related Party” or parties and the Company. An Interested Transaction is a transaction or arrangement in which the aggregate amount involved will or may be expected to exceed $120,000 in any calendar year and in which the Company and/or any Related Party may have an interest. A Related Party includes an executive officer, director or nominee for election as a director of the Company, any holder of more than a 5% beneficial ownership interest in the Company, any immediate family member of any of the foregoing, or any firm, corporation or entity in which any of the foregoing persons is employed or is a general partner or principal or in which such person or persons collectively have a 10% or greater beneficial ownership interest.
The General Counsel is responsible for identifying potential Interested Transactions and determining whether a proposed transaction is an Interested Transaction and accordingly, reportable to the Audit & Finance Committee for consideration at its next regularly scheduled meeting. The Audit & Finance Committee will review the material facts of all Interested Transactions and report its recommendations to the Board which will either approve or disapprove the Interested Transaction.
The Audit & Finance Committee and the Board have reviewed and determined that certain categories of Interested Transactions are deemed to be
pre-approved
or ratified (as applicable) by the Board under the terms of the policy. These are: (a) the employment and compensation arrangements of named executive officers required to be reported in the Company’s proxy statement; (b) Director compensation required to be reported in the Company’s proxy statement; (c) ordinary course charitable contributions periodically reviewed by the Compensation Committee of the Board; and (d) ordinary course business transactions conducted on an “arm’s length” basis with Galderma S.A. (of which Dr. Flemming Ornskov is Chief Executive Officer), Avient Corp. (of which Mr. Fearon is an independent director but not an employee) and Baxter International Inc. (of which Ms. Knight is Executive Vice President and Group President, Medical Products & Therapies).
Insider Trading Policy
The Board has adopted a written Insider Trading Policy and the Company has implemented associated procedures, both of which have been reasonably designed to promote compliance with insider trading laws, rules and regulations, and the applicable NYSE listing standards. The policy applies to all Directors, officers and employees of the Company and its subsidiaries, as well as the immediate families, personal households and entities controlled by such Directors, officers and employees. The policy covers transactions in all securities of the Company, including common stock, options to purchase common stock, restricted stock units, debt securities, preferred stock, convertible debentures, and warrants as well as derivative securities, such as exchange-traded options or swaps. The policy strictly prohibits trading in any Company securities while in possession of material
non-public
information, except under
pre-approved
trading plans that meet the requirements of Rule
10b5-1
under the Exchange Act
(“10b5-1
trading plans”), and misusing such information, such as by “tipping” material
non-public
information or making unauthorized disclosure. In addition, the policy specifies our open quarterly trading windows (and who is subject to such windows), our
pre-clearance
procedures (and who is subject to such procedures) and requirements regarding
pre-approved
10b5-1
trading plans. Persons who fall within the scope of the policy are also prohibited from making short sales of Company stock or trading in options on Company stock and purchasing financial instruments, including prepaid variable forward contracts, equity swaps, collars, or units of exchange funds, that are designed to hedge or offset any decrease in market value of the Company’s securities. The foregoing summary of Waters’ Insider Trading Policy does not purport to be complete and is qualified in its entirety by reference to the full text of the Insider Trading Policy, a copy of which is filed as Exhibit 19.1 to Waters’ Annual Report on Form
10-K
for the fiscal year ended December 31, 2024.
Stock Ownership Guidelines
In order to closely align Directors’ and executive officers’ interests with those of the Company’s shareholders, the Company has minimum stock ownership guidelines for its executive officers and
non-employee
Directors. These guidelines require the accumulation by anyone who holds the CEO position of common stock equal to five times his or her base salary over a three-year period and the accumulation by our other executive
20

Table of Contents

officers of common stock equal to two times their base salary over a five-year period. The stock ownership guidelines for
non-employee
Directors require the accumulation of a minimum of five times the annual cash Board retainer over a five-year period. Please refer to the section “— Compensation Discussion and Analysis — Compensation Philosophy, Governance, and Pay Practices — Stock Ownership Guidelines” for additional details regarding our stock ownership guidelines.
Guidelines, Code of Conduct, Global Complaint Reporting Policy, and Ethics Helpline
The Board has adopted the Guidelines, a Global Code of Business Conduct and Ethics for employees, executive officers, and Directors, and a Global Complaint Reporting Policy (sometimes called the Company’s “whistleblower” policy) regarding the treatment of potential legal and compliance concerns, including those relating to accounting, internal accounting controls, and auditing matters. The Waters Ethics Helpline, which is operated confidentially by a third-party vendor, provides the Waters workforce and others a comprehensive and anonymous reporting tool to report concerns. All of the foregoing documents are available on the Company’s website at ir.waters.com/esg/governance-documents and copies may be obtained, without charge, upon written request to the Company, c/o Secretary, at 34 Maple Street, Milford, MA 01757. The Waters Ethics Helpline may be accessed at waters.ethicspoint.com.
Risk Oversight
Board’s Role in Risk Oversight Generally
Included in the Company’s Annual Report are the risk factors affecting the Company, which are periodically reviewed by the Board and the Audit & Finance Committee and updated or expanded as warranted. The Board is responsible for overseeing the management and operations of the Company, including its risk assessment and risk management functions. The Board has delegated responsibility to reviewing the Company’s policy with respect to risk assessment and management, including with respect to cybersecurity, to the Audit & Finance Committee.
Additionally, the Company has an enterprise risk management framework under the oversight of the Vice President, Internal Audit, which includes an information security risk management framework under the specific oversight of the Vice President and Chief Information Officer. This program seeks to identify new risks, develop and implement risk mitigation plans, and monitor the results affecting the Company’s business and operations on an ongoing basis. Management of the Company actively participates in this program and briefs the Board on the strategic, operational, compliance, and financial risks affecting the Company and efforts undertaken to mitigate them. The Compensation Committee has responsibility for oversight of risk related to compensation matters as more fully described below.
Cybersecurity Risk Oversight
The Board, including the Audit & Finance Committee, oversees the Company’s information security risk management framework that seeks to identify new risks, develop and implement risk mitigation plans, and monitor the results affecting the Company’s business and operations on an ongoing basis. The Company’s risk management framework is under the specific oversight of the Company’s Vice President and Chief Information Officer (the “CIO”). The CIO manages this framework, in collaboration with the Company’s businesses and functions. The CIO presents updates to the Audit & Finance Committee on a quarterly basis and to the full Board at least annually. These reports include detailed updates on the Company’s performance preparing for, preventing, detecting, responding to and recovering from cyber incidents. The CIO also promptly informs and updates the Audit & Finance Committee and, as necessary, the Board of Directors about any information security incidents that may pose significant risk to the Company. The Company’s program is periodically evaluated by external experts, and the results of those reviews are reported to the Audit & Finance Committee and the Board. Together with management, the Audit & Finance Committee reviews the Company’s risk assessment and risk management practices and discusses major cybersecurity risk exposures as well as steps taken by management to monitor and control such exposures.

Compensation-Related Risk
The Compensation Committee conducted its annual review to determine if any of the Company’s compensation plans or practices would be reasonably likely to have a material adverse effect on the Company. The Compensation Committee reviewed various components and aspects of the Company’s compensation plans and practices, including their size, scope, and design. The Compensation Committee also reviewed whether the compensation plans and practices promote unnecessary risk-taking and the policies in place to mitigate risk associated with these plans. The review included an assessment of design features that could encourage excessive risk-taking and the potential magnitude of such risks, including design features such as a short-term oriented pay mix, overly aggressive goal setting, and over-weighting of annual incentives as compared to long-term incentives. The policies that exist to mitigate compensation-related risk include, among others, (1) the Company’s recoupment policies; (2) stock ownership guidelines for executive officers; (3) a five-year vesting period for stock options and three- to five-year vesting periods for RSUs; (4) a three-year performance period and a maximum payout cap for performance-based restricted stock units (“PSUs”); (5) a prohibition on hedging; (6) a required post-vesting holding period for PSUs; and (7) the independent oversight of compensation programs by the Compensation Committee, with input from an independent compensation consultant. In addition, several features of the Company’s annual incentive plan (the “AIP”) mitigate compensation-related risk, including the use of payout caps, a clear link between payouts under the plan and the Company’s financial performance, and the Compensation Committee’s oversight in determining payouts under the plan. Based on this review, the Compensation Committee and the Company do not believe that there are any compensation-related risks arising from the Company’s compensation plans and practices that would be reasonably likely to have a material adverse effect on the Company.
ESG Risk Oversight
The Board, with and through its Nominating and Corporate Governance Committee, as appropriate, oversees the Company’s management of ESG matters, including risks related to our governance structure, environmental impact and human capital, among other topics. The Nominating and Corporate Governance Committee is responsible for reviewing and reporting to the Board on the Company’s policies and practices with respect to ESG matters, including the business impact of ESG matters on the Company.
HOW WE ARE ORGANIZED
Board Leadership Structure
As stated in the Company’s Guidelines, the Board has no set policy with respect to the separation of the offices of Chair and CEO. In 2024, Dr. Flemming Ornskov served as Chair of the Board and Dr. Batra served as President and CEO of the Company. While no written policy currently exists, the Board believes that separating the offices of Chair and CEO facilitates an appropriate balance between strong and consistent leadership and independent and effective oversight of the Company’s business by the Board.
Role of Compensation Consultant, Compensation Committee, and Management in Decision-Making
The Compensation Committee engaged Pearl Meyer as its outside independent compensation consultant during 2024. Pearl Meyer participates in Compensation Committee meetings and executive sessions and advises the Compensation Committee on a range of executive officer and Director compensation matters, including annual and long-term incentive plan design, competitive market assessments, compensation trends and best practices, and technical and regulatory developments. Pearl Meyer provides services to the Compensation Committee related only to executive officer and Director compensation, including peer group composition, comparing executive officer and Director compensation arrangements to those of the peer group and the broader market, and providing market data and advice regarding executive and Director compensation plans. The Compensation Committee has the authority to engage and terminate independent legal, accounting, and other advisors as it deems necessary or appropriate to carry out its responsibilities.
22

Table of Contents

The Compensation Committee regularly reviews the services provided by Pearl Meyer and has determined that Pearl Meyer is independent in providing consulting services to the Compensation Committee. The Compensation Committee conducted a review of its relationship with Pearl Meyer in 2024 and determined that Pearl Meyer’s work for the Compensation Committee did not raise any conflicts of interest, considering the factors set forth in the applicable rules of the SEC and the New York Stock Exchange.
The Compensation Committee approves all compensation decisions for our named executive officers, after consulting with Pearl Meyer, as appropriate. The Senior Vice President, Global Human Resources and the Vice President, Total Rewards also provide the Compensation Committee with information and analysis on the Company’s executive compensation programs, as requested. In the beginning of 2024, our President and CEO, Dr. Batra, provided the Compensation Committee with his assessment of the performance of the Company and the other named executive officers, and made compensation recommendations for such other named executive officers. The Compensation Committee, however, makes all final decisions with respect to the compensation of the CEO and the other named executive officers. No named executive officer makes any decision or recommendation to the Compensation Committee on any element of his or her own compensation.
DIRECTOR MEETINGS AND BOARD COMMITTEES
Meetings
The Board held 11 meetings during the year ended December 31, 2024, which included sessions on strategy; innovation; enterprise risk management; cybersecurity; annual operating plan; talent review; succession; and ESG.
During 2024, the Audit & Finance Committee met ten times, the Compensation Committee met three times, the Nominating and Corporate Governance Committee met three times, and the Science and Technology Committee met two times. All of the Company’s Directors attended at least 75% of the aggregate number of meetings of the Board and each Director’s respective regular committees that were held during the period for which such Director served in 2024. Information regarding our standing Board committees, their members and the number of meetings held during 2024 is set forth below.
The Company encourages Director attendance at annual shareholder meetings but does not have a formal policy requiring attendance. All Directors who were then members of the Board attended the 2024 annual meeting of shareholders.

REPORT OF THE AUDIT AND FINANCE COMMITTEE OF THE BOARD OF DIRECTORS
The information contained in this report shall not be deemed to be “soliciting material” or “filed” except to the extent that Waters specifically incorporates it by reference into a document filed under the Securities Act of 1933, as amended, or the Exchange Act.
During 2024
,
the Audit & Finance Committee of the Board, in conjunction with management and PwC, the Company’s independent registered public accounting firm, focused on the following items:
1. Compliance with Section 404 of the Sarbanes-Oxley Act of 2002 (the “Act”) and the adequacy of Company internal controls;
2. The appropriateness of Company financial reporting and accounting processes;
3. The independence and performance of the Company’s independent registered public accounting firm;
4. Company compliance with laws and regulations, including compliance with applicable provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010; and
5. Review of the Company’s independent registered public accounting firm’s quality control procedures.
The Company’s compliance with Section 404 of the Act is managed primarily by the Company’s Vice President, Internal Audit in conjunction with the Company’s Senior Vice President and Chief Financial Officer. During 2024, the Audit & Finance Committee received regular and detailed briefings from the Company’s Vice President, Internal Audit and PwC regarding the Company’s compliance with Section 404 of the Act. On February 20, 2025, the Company’s Vice President, Internal Audit and PwC reported to the Audit & Finance Committee that no material weaknesses had been identified in the Company’s internal control over financial reporting as of December 31, 2024.
The Board has adopted a written charter setting out more specifically the functions that the Audit & Finance Committee is to perform. The charter is reviewed on an annual basis by the Audit & Finance Committee and the Audit & Finance Committee is advised as to any corporate governance developments which may warrant charter amendments. The charter is available on the Company’s website at ir.waters.com/esg/governance-documents. A discussion of the Audit & Finance Committee’s role in risk oversight can be found under the heading “— Risk Oversight — Board’s Role in Risk Oversight Generally” above.
As stated in its charter, the Audit & Finance Committee is tasked with, among other things, reviewing with management the Company’s guidelines and policies with respect to its approach to risk assessment and risk management. In addition, major financial risk exposures and means of monitoring and controlling these exposures, is to be discussed with management.
The Audit & Finance Committee held 10 meetings during the fiscal year ended December 31, 2024. The Audit & Finance Committee reviewed on a quarterly basis, with members of the Company’s management team, the Company’s quarterly and annual financial results prior to the release of earnings and the filing of the Company’s quarterly and annual financial statements with the SEC. The Board has determined that each of the three current members of the Audit & Finance Committee — Ms. Baddour (Chair), Mr. Dan Brennan and Mr. Richard Fearon — is an “audit committee financial expert” as defined under the applicable rules and regulations of the SEC and has “accounting or related financial management expertise” within the meaning of the New York Stock Exchange rules. Company management has primary responsibility for the financial statements and reporting processes. The Company’s independent registered public accounting firm, PwC, audits the annual financial statements and is responsible for expressing an opinion on their conformity with generally accepted accounting principles (“GAAP”).

Table of Contents

The Audit & Finance Committee has adopted the following guidelines regarding the engagement of PwC to perform
non-audit
services for the Company:

• |  | Company management will submit to the Audit & Finance Committee for approval a list of non-audit services that it recommends the Audit & Finance Committee engage its independent registered public accounting firm to provide from time to time during the fiscal year and an estimated amount of fees associated with such services. Company management and the Company’s independent registered public accounting firm will each confirm to the Audit & Finance Committee that each non-audit service on the list is permissible under all applicable legal requirements. The Audit & Finance Committee will, in its discretion, either approve or disapprove both the list of permissible non-audit services and the estimated fees for such services. The Audit & Finance Committee will be informed routinely as to the non-audit services actually provided by the Company’s independent registered public accounting firm pursuant to this pre-approval process and the actual expenditure of fees associated therewith as well as new non-audit services being requested for approval.

• |  | To ensure prompt handling of unexpected matters, the Audit & Finance Committee delegates to its Chair the authority to amend or modify the list of approved permissible non-audit services and fees. The Chair will report action taken to the Audit & Finance Committee at the next Audit & Finance Committee meeting.

• |  | PwC and the Company will each ensure that all audit and non-audit services provided to the Company have been pre-approved by the Audit & Finance Committee.

The Audit & Finance Committee hereby reports for the fiscal year ended December 31, 2024, that:
1. It has reviewed and discussed the Company’s audited financial statements for the fiscal year ended December 31, 2024 with Company management;
2. It has reviewed and discussed with PwC those matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the Commission;
3. It has received from PwC written disclosures and a letter required by the applicable requirements of the PCAOB regarding PwC’s communications with the Audit & Finance Committee concerning independence, and has discussed with PwC its independence;
4. It has considered whether, and determined that, the provision of
non-audit
services to the Company by PwC as set forth below, was compatible with maintaining auditor independence; and
5. It has reviewed and discussed with PwC its internal quality control procedures, and any material issues raised by the most recent internal quality control review, or peer review, or by any inquiry or investigation by governmental or professional authorities within the preceding five years.
Based on the items reported above, on February 20, 2025, the Audit & Finance Committee recommended to the Board that the Company’s audited financial statements be included in the Company’s Annual Report on
Form 10-K
for the fiscal year ended December 31, 2024 for filing with the SEC. The recommendation was accepted by the Board on February 20, 2025.

PROPOSAL 3 —
NON-BINDING
ADVISORY VOTE ON COMPENSATION OF EXECUTIVE OFFICERS
Under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), the shareholders of Waters are entitled to cast a
non-binding
advisory vote at the Annual Meeting to approve the compensation of the Company’s named executive officers, as disclosed in this Proxy Statement. Pursuant to the Dodd-Frank Act, the shareholder vote is an advisory vote only, and is not binding on Waters or the Board.
Although the vote is
non-binding,
the Compensation Committee and the Board value your opinions and will consider the outcome of the vote in establishing and evaluating the Company’s executive compensation program and making future compensation decisions.
As described more fully in the Compensation Discussion and Analysis, the Summary Compensation Table, and the other tables following the Summary Compensation Table, we believe the Company’s named executive officers are compensated in a manner consistent with our business strategy, competitive practice, and sound compensation governance principles, and with a focus on short- and long-term performance-based compensation.
Please refer to the section “— Compensation Discussion and Analysis” for a full description of our executive compensation practices and programs.
We are requesting your
non-binding
advisory vote on the following resolution:
“RESOLVED, that the compensation of the Company’s named executive officers as described in the Compensation Discussion and Analysis and in the Summary Compensation Table and subsequent tables is approved.”
Required Vote and Recommendation of the Board of Directors
Approval, on an advisory basis, of the proposal requires a majority of the votes cast in person or by Proxy by the shareholders entitled to vote thereon. Abstentions and broker
non-votes
will be counted as present for the purpose of determining whether a quorum is present but will not be treated as votes cast with respect to the proposal and therefore will not have an effect on the determination of whether the proposal has been approved on an advisory basis. If you own shares through a bank, broker, or other holder of record, you must instruct your bank, broker or other holder of record how to vote in order for them to vote your shares so that your vote can be counted on this proposal.

COMPENSATION OF DIRECTORS AND EXECUTIVE OFFICERS
EXECUTIVE SUMMARY
Our Named Executive Officers
The purpose of this Compensation Discussion and Analysis (this “CD&A”) is to provide information about the material elements of compensation that are paid to, awarded to, or earned by, our named executive officers for fiscal year 2024 (whom we collectively refer to as our “NEOs”). The NEOs, who consist of any individual who served as our principal executive officer during fiscal year 2024, any individual who served as our principal financial officer during fiscal year 2024, and our two most highly compensated executive officers who were serving at the end of fiscal year 2024 other than our principal executive officer and principal financial officer.
Our NEOs for fiscal year 2024 (and their respective positions) were as follows:

Udit Batra, Ph.D. President & CEO |  | Amol Chaubal Senior Vice President and Chief Financial Officer
Jianqing Y. Bennett Senior Vice President, TA Instruments Division and Clinical Business Unit |  | Robert Carpio III Senior Vice President, Waters Division (1)

(1) | Mr. Carpio was appointed as the Company’s Senior Vice President, Waters Division effective as of June 24, 2024.

Our Business
Waters Corporation, a global leader in analytical instruments, separations technology, and software, has pioneered innovations in chromatography, mass spectrometry, and thermal analysis serving the life, materials, food, and evironmental sciences for more than 65 years. Our Company helps ensure the efficacy of medicines, the safety of food and the purity of water, and the quality and sustainability of products used every day.
With approximately 7,600 employees worldwide, Waters operates directly in over 35 countries, including 15 manufacturing facilities. Together with our customers in labs, manufacturing sites, and hospitals in over 100 countries around the world, we accelerate the benefits of pioneering science to improve human health and well-being, helping to leave the world better than we found it.
Our Performance
In 2024, the Company’s revenue growth was flat on both a GAAP and adjusted
non-GAAP
organic constant currency basis, as compared to 2023. Our 2024 sales grew in most major geographies; except for in China. China’s revenue declined by 10% due to lower customer demand for our instrument systems and chemistry products
31

Table of Contents

as a result of increased government regulations and macroeconomic conditions. The Wyatt acquisition contributed 1% to revenue growth in 2024 as compared to 2023. Despite weak market conditions in China and headwinds from foreign exchange and inflationary costs, our adjusted operating margin percentage expanded for the year. Our net income decreased by 1% on a GAAP basis and increased by 1% adjusted
non-GAAP
organic basis, respectively, as compared to 2023. Adjusted
non-GAAP
organic constant currency revenue and adjusted
non-GAAP
organic net income are financial measures that are not prepared in accordance with GAAP. Appendix A to this Proxy Statement defines these and other adjusted
non-GAAP
financial measures and reconciles them to the most directly comparable historical GAAP financial measures.
The Company maintains a strong balance sheet, access to liquidity, and a well-structured debt maturity profile. This strength allows us to prioritize investing in growth. We continue to evaluate M&A opportunities that will enhance value creation for our shareholders.
The Company has consistently delivered top tier value to shareholders over the long-term. Since the beginning of our transformation in July of 2020, our TSR is ahead of all other major Life Science Tools peers
1
through December 31, 2022, 2023 and 2024, delivering 90%, 83%, and 106% TSR, respectively. In 2024, the company delivered 13% TSR in a difficult environment, which was again the highest amongst Life Science Tools peers.
2024 Executive Compensation Program Outcomes
Our program aligns executive compensation to the successful execution of our strategy, meeting our financial and operational goals and delivering strong returns to our shareholders. We attract and retain exceptional talent needed for long-term success by ensuring our compensation is market competitive with our peers.
Our incentive plans focus on absolute and relative financial performance, and we set stretch goals that we believe align with delivering strong returns for our shareholders. For our 2024 Annual Incentive Plan (“AIP”), we were below target on both corporate performance metrics, which were adjusted
non-GAAP
organic constant currency revenue growth (“OCCRG”) and adjusted
non-GAAP
organic net income growth (“ONIG”). For the performance-based restricted stock units (“PSUs”) that were granted in 2022 and whose performance period ended in 2024, we were below target on the applicable OCCRG performance metric, and we were above the median of the S&P 500 Healthcare index on the applicable Relative Total Shareholder Return (“rTSR”) performance metric.
Further details on each of these programs, including a description of the relevant performance goals and their 2024 outcomes, are provided later in this CD&A.

2024 EXECUTIVE COMPENSATION PROGRAM
Compensation Philosophy
The Company’s executive compensation program is intended to be both performance-based and market-competitive. A summary of the Company’s executive compensation program philosophy is as follows:

Objectives

✓ To focus executives on achieving financial and operating objectives that enhance long-term shareholder value ✓ To align the interests of executives with the Company’s shareholders ✓ To attract and retain executive talent |  |

Executive Compensation Strategy |  |  |  | Long-Term Alignment |  |
Performance-Driven Approach : Rewards executives for sustained achievement of financial and operational goals. Market-Based Salaries : Base salaries are targeted at the market median, adjusted for performance, tenure, and experience. Incentive Alignment : Annual incentive awards are set at market median, and long-term incentive awards target market median, tied to challenging performance targets. Shareholder Alignment : Compensation structure ensures executives’ interests align with shareholder value through performance-based rewards. Total Compensation Alignment: Total Compensation is targeted at market median. |  |  |  | Equity-Based Awards : Annual long-term incentive equity-based awards balance share price appreciation, long-term financial performance and retention. Grants generally include stock options, time-based restricted stock units (“RSUs”) and/or PSUs, with RSUs typically being granted for new hires and promotions. Performance & Growth Focus : Stock options and RSUs increase in value as our stock price increases. PSUs vest based on achievement of the specified performance goals. Market-Based Targets : Long-term incentive award target opportunities are generally set at market median, with adjustments based on performance and role. Retention & Alignment : Multi-year vesting periods and post-vesting holding requirements ensure long-term executive and shareholder alignment. |  |

In addition to the philosophy and structure of the executive compensation program as described above, the Compensation Committee also considers, as appropriate, the compensation practices for all Waters employees in reviewing the compensation for our NEOs.

Compensation Governance and Pay Practices
Waters maintains strong pay and governance practices as outlined below. A full description of these policies and practices can be found in the discussion below in the section entitled “— Elements of Executive Compensation.”

What We Do |  |  |  | What We Don’t Do |  |
✓ Post-vesting holding periods for PSU awards |  |  |  | × No excessive executive perquisites |  |
✓ Mandatory compensation recoupment policy for incentive-based compensation |  |  |  | × No new or legacy excise tax gross-up provisions |  |
✓ Annual compensation risk assessment |  |  |  | × No option repricing without shareholder consent |  |
✓ Anti-hedging policy |  |  |  | × No ad-hoc discretionary or guaranteed annual cash bonus payments for NEOs |  |
✓ Independent compensation consultant |  |  |  |  |  |
✓ Double-trigger for accelerated equity vesting in connection with a change of control |  |  |  |  |  |
✓ Robust director and executive officer stock ownership guidelines |  |  |  |  |  |

Pay Mix
Consistent with our performance-based compensation philosophy,
at-risk
compensation comprises a substantial portion of the NEOs’ target total direct compensation, consisting of base salary and short- and long-term incentives. For fiscal year 2024,
at-risk
compensation represented approximately 90% of the target total direct compensation for Dr. Batra, and approximately 78% of the target total direct compensation for our other NEOs as a group.
The chart below details the target total direct compensation pay mix for our CEO and the average of our other NEOs for fiscal year 2024:

2024 Target Pay Mix
CEO |  | Average Other NEOs

2024 Key Business Priorities and Connection to our Executive Compensation Program
In fiscal year 2024, the Compensation Committee utilized OCCRG and ONIG as the performance metrics under the AIP for our NEOs. Use of an OCCRG performance metric supports the Company’s belief that revenue growth drives our overall success and enables us to continue to invest in future growth and innovation. The OCCRG
34

Table of Contents

performance goals are based on revenue reported in accordance with GAAP but measure the change in net revenue between two periods, without taking into account the impact of foreign currency exchanges rates during the period and excluding the impact of acquisitions made within twelve months of the acquisition close date.
Use of an ONIG performance metric promotes executive team alignment, focuses the executive team on operational efficiencies and profitable growth, provides a long-term perspective among executives and drives long-term shareholder value. The ONIG performance goals are based on the Company’s net income reported in accordance with GAAP, but adjusted to exclude certain charges and credits, net of tax, including, but not limited to, purchased intangibles amortization, acquired
in-process
research and development, restructuring costs and certain other items, pension costs, litigation provisions and certain income tax items. The Company considers these items not directly related to ongoing operations and performance, and therefore excludes them from the performance goals set under the AIP. Net income was also adjusted to exclude the impact of acquisitions made within twelve months of the acquisitions’ close date, so the performance goals set under the AIP are more directly related to ongoing operations and performance and comparable to the prior year.
Use of Adjusted
Non-GAAP
Financial Metrics in our Executive Compensation Program
The Company generally uses adjusted
non-GAAP
financial metrics to facilitate financial and operational decision-making, evaluate historical operating results, make comparisons to competitors’ operating results and determine management incentive compensation. Appendix A to this Proxy Statement defines the following adjusted
non-GAAP
financial measures and reconciles them to the most directly comparable historical GAAP financial measures.

| (1) | Non-GAAP Organic Constant Currency Revenue Growth (OCCRG) : The Company believes that referring to comparable OCCRG rates is a useful way to evaluate the underlying performance of the Company’s net revenue. OCCRG rate, a non-GAAP financial metric, measures the change in net revenue between current- and prior-year periods, excluding the impact of foreign currency exchange rates during the current period and excluding the impact of acquisitions made within twelve months of the acquisition close date. In fiscal year 2024, the impact of foreign currency exchange rates decreased our GAAP revenue by approximately 1%, while the impact of acquisitions increased our GAAP revenue by approximately 1% as compared to fiscal year 2023.

| (2) | Non-GAAP Organic Net Income Growth (ONIG) : The Company’s adjusted non-GAAP organic net income growth is based on net income reported in accordance with GAAP, but adjusted to exclude certain charges and credits that the Company considers not directly related to ongoing operations and overall performance of the Company. In fiscal year 2024, GAAP net income was adjusted to exclude purchased intangibles amortization, restructuring costs and certain other items, acquisitions related costs, retention bonus obligation, and certain income tax items. Net income was also adjusted to exclude the impact of acquisitions made within twelve months of the acquisition close date. The impact of these adjustments to GAAP net income for fiscal year 2024 increased our adjusted non-GAAP ONIG by 11% as compared with our GAAP net income growth.

COMPENSATION SETTING PROCESS
Competitive market data is an important factor used by the Compensation Committee in determining the amount of each element of compensation for our NEOs. The Compensation Committee engages Pearl Meyer as an independent consultant to provide advice and analysis on the structure of our executive compensation program as well as competitive data on pay levels. Pearl Meyer prepares this competitive assessment annually for the Compensation Committee. The Compensation Committee reviews the target total direct compensation of each NEO. The Compensation Committee also reviews each NEO’s total compensation opportunity to ensure that it contains an appropriate level of performance-based compensation and is designed to meet the overall objectives of our executive compensation program. The Compensation Committee considers a range of factors in determining the amount of each compensation element for each NEO, including, without limitation, Company performance, individual performance and experience, competitive market data, hiring and retention needs, scope of responsibility and an individual’s potential for making future contributions to the Company. Pursuant to the
35

Table of Contents

SEC’s rules, the Compensation Committee has reviewed the SEC’s independence factors for compensation advisers and concluded that no conflict of interest exists that would prevent Pearl Meyer from independently representing the Compensation Committee.
Pearl Meyer and the Compensation Committee utilize a core industry peer group of 17 publicly traded companies in the life sciences and analytical instrument industry with generally similar revenues and market capitalization as Waters.
The industry peer group used for fiscal year 2024 executive compensation decisions was comprised of the following companies.

Peer Companies
Agilent |  | Avantor |  | Bio-Rad Laboratories
Bio-Techne |  | Catalent |  | Charles River Laboratories
Cooper Companies |  | Edwards Lifesciences |  | Hologic
IDEXX Laboratories |  | Illumina |  | Mettler-Toledo
ResMed |  | Revvity |  | STERIS
Teleflex |  | West Pharmaceutical |  |

Each year, Pearl Meyer evaluates the peer group for its continued appropriateness for external executive compensation comparisons based on the primary selection criteria of similarity in industry, products and services, revenue and market capitalization. At the time the peer group was originally selected, we targeted peers with both revenue and market capitalization ranging between 33% to 300% of Waters’ revenue and market capitalization. The Compensation Committee monitors the peer group year to year to determine if changes are needed.
For fiscal year 2024, the Compensation Committee completed an analysis of the median revenue and market capitalization of the peer group, and determined no adjustment was required for the peer group. For fiscal year 2025, the Compensation Committee removed Catalent from the peer group due to its acquisition at the end of 2024.
The chart below represents the Company’s position relative to the companies in our fiscal year 2024 peer group, with regard to market capitalization as of December 31, 2024 and revenue during the 2024 fiscal year.
36

Table of Contents

Pearl Meyer and the Compensation Committee also utilize independent, globally recognized executive compensation published surveys. The Compensation Committee uses this broad survey data in combination with the peer group data in evaluating our NEOs’ compensation. The Compensation Committee does not rely upon data from any one individual company included in any of these surveys in making compensation decisions. Data from these surveys and/or the peer companies are combined to develop a primary market composite, which the Compensation Committee uses to compare our NEOs’ compensation against the market.
ELEMENTS OF EXECUTIVE COMPENSATION
There are three primary elements of our executive compensation program: base salary, annual incentive cash awards and long-term incentive equity-based awards. Each element addresses specific objectives of this program, and together they are intended to meet the overall philosophy and objectives of our executive compensation program as described above. The mix of short-term cash incentives and long-term equity incentives focus executives on the achievement of annual and longer-term financial and operating objectives that drive long-term shareholder value. The design of these incentive programs fosters a high degree of performance orientation through the measures chosen for each plan, which emphasize sales growth, profitability and TSR. The short- and long-term incentive plans also enable significant differentiation among individuals through the use of an individual performance modifier under the AIP (as further described below), and long-term incentive equity award grant values based on a number of factors, including, without limitation, individual performance, experience and competitive market data.
The Compensation Committee reviews the NEOs’ total direct compensation (measured at target for annual and long-term incentives, as applicable, and assuming target performance for PSUs), in order to appropriately position the NEOs’ target total direct compensation to both the market and the Company’s objectives. While the structure of pay is similar for each NEO, the amounts differ based on several factors, including, without limitation, position specific market data, the critical nature of the NEO’s position to the business, and the NEO’s level of contribution.

|  | Base Salary |  | Annual Cash Incentive |  | Long-Term Performance-Based Equity Incentive
|  | Attract and retain executives and other key employees |  | Motivate executives and other key employees to achieve challenging financial and operational goals as established by the Compensation Committee at the start of the fiscal year |  | Motivate executives and other key employees to contribute to the Company’s long-term growth of shareholder value, align compensation with stock price growth and achievement of strategic growth goals, and retain executives and other key employees

Base Salary
The base salaries for the NEOs are reviewed annually by the Compensation Committee. Consistent with the compensation practices established for all Company employees, the individual salaries for the NEOs are determined based upon a combination of factors, including, without limitation, past individual performance and experience, Company performance, scope of responsibility and annual base salary increase guidelines. The Compensation Committee considers all these factors in determining base salary and base salary increases and does not assign a specific weighting to any individual factor.
The Compensation Committee also considers the competitive market position of each NEO’s base salary. Any base salary increases are generally approved by the Compensation Committee in February of the applicable fiscal year. The competitive assessments completed by Pearl Meyer at the end of fiscal year 2023 provided the market information used in determining the base salaries for our NEOs in fiscal year 2024.
Based on Pearl Meyer’s market assessment of the overall environment for base salary increases, in addition to the individual’s performance and contribution, the Compensation Committee increased the base salary for

Mr. Chaubal and Ms. Bennett in fiscal year 2024, effective as of September 1, 2024. These increases were made effective later in the year, as opposed to the beginning of the year, as part of our 2024 cost savings effort.
The annualized base salaries paid to our NEOs in fiscal years 2024 and 2023 are set forth in the chart below.

Named Executive Officer |  | Base Salary (as of 12/31/23) |  | Base Salary (as of 12/31/24) |  | Percent Increase
Udit Batra, Ph.D. |  | $1,100,000 |  | $1,100,000 |  | 0.0%
Amol Chaubal |  | $565,000 |  | $580,000 |  | 2.7%
Jianqing Y. Bennett |  | $602,000 |  | $615,000 |  | 2.2%
Robert Carpio(a) |  | N/A |  | $580,000 |  | N/A

(a) | Mr. Carpio joined the Company on June 24, 2024 and did not receive a base salary increase during fiscal year 2024.

Annual Incentive Awards
The AIP is the short-term incentive plan for our NEOs, other executives, and other key employees. Target annual incentive cash bonuses for each NEO under the AIP are based on a percentage of the executive’s base salary, with the actual bonus payout amount determined based on achievement of Company performance goals pre-established by the Compensation Committee.
Under the AIP, threshold-level performance achievement results in a payout of 0.25x of target, target-level performance achievement results in a payout of 1.0x of target, and maximum-level performance achievement results in a payout of 2.0x of target. Payouts under the AIP are interpolated for performance between these threshold, target and maximum levels. There is no payout under the AIP for performance below threshold. The Compensation Committee believes that this maximum payout opportunity is consistent with the Company’s philosophy to position total target cash compensation at the median of the market and to provide the opportunity for greater reward for overachievement of challenging performance goals.
Prior to the application of any individual performance modifier, the threshold, target and maximum levels under the AIP (each measured as a percentage of base salary) for Dr. Batra are equal to 31.3%, 125% and 250%, respectively. The threshold, target and maximum levels under the AIP (each measured as a percentage of base salary) for Messrs. Chaubal and Carpio, and Ms. Bennett, are equal to 18.8%, 75% and 150%, respectively.
The Compensation Committee periodically reviews the Company’s AIP structure with Pearl Meyer. The objectives of this review are to consider the alignment of this plan with our compensation philosophy and emphasis on pay-for-performance, and to review the performance metrics and goals utilized under the plan to ensure they provide the best ongoing motivators for our executives and other key employees to execute our business strategy and create shareholder value.
2024 Annual Incentive Plan Structure
Company Performance Goals
For fiscal year 2024, the AIP utilized two performance goals, OCCRG and ONIG (each as defined and further described above). The Compensation Committee determined to use OCCRG because it reinforces the Company’s belief that revenue growth drives our overall success and enables us to continue to invest in future growth and innovation. The Compensation Committee determined to use ONIG because it incentivizes operational results and reflects the ongoing operational efforts of our executives and other employees.

Table of Contents

The following table outlines these performance goals for our 2024 AIP, including target, actual performance and payout percentage:

2024 Performance Metric |  | Threshold Performance ($000) |  | Target Performance ($000) |  | Maximum Performance ($000) |  | Actual Performance ($000) |  | Payout (%)
2024 adjusted non-GAAP organic revenue in constant currency |  | $2,847,300 |  | $3,029,000 |  | $3,241,000 |  | $2,948,800 |  | 66.9%
2024 adjusted non-GAAP organic net income |  | $639,800 |  | $727,000 |  | $807,000 |  | $709,100 |  | 84.5%

Appendix A to this Proxy Statement defines OCCRG, ONIG and other adjusted
non-GAAP
financial measures, and reconciles them to the most directly comparable historical GAAP financial measures.
Individual Performance Goals
The AIP also incorporates an individual performance modifier in its plan design, which allows the Compensation Committee to distinguish an individual’s contribution to the overall results achieved against the
pre-established
corporate performance goals by increasing or decreasing an individual’s payout up to 50%, while maintaining specific, measurable objectives. The maximum payout opportunity for the NEOs under the 2024 AIP was equal to 200% of the applicable NEO’s target annual bonus.
Ambitious annual individual performance objectives are set for each NEO under the AIP. In 2024, the NEOs’ individual performance exceeded their objectives, which is reflected in the following individual performance modifier percentages under the 2024 AIP: Dr. Batra- 115%, Mr. Chaubal- 115%, Ms. Bennett- 105% and Mr. Carpio- 100%, due to his tenure. Our NEOs individual performance in the following three strategic areas delivered leading-industry growth for our Company:

| • |  | Regained commercial momentum by executing key commercial growth initiatives in instrument replacement, service plan attachment, eCommerce adoption, contract organizations and launch excellence, delivering strong operational performance in a challenging environment;

| • |  | Revitalized innovation through product launches across several significant areas including the Alliance IS, Xevo TQ Absolute and MaxPeak Premier columns;

| • |  | Strengthened our position by entering faster growth adjacencies through organic and inorganic investments in bio-separations, bioanalytical characterization, clinical and battery testing.

Assessment of the 2024 Annual Incentive Plan
As discussed in detail below, the Compensation Committee establishes annual Company performance goals which are intended to be challenging but achievable if Company performance is strong.

(a) | Mr. Carpio’s annual bonus was prorated based on his start date of June 24, 2024.

Long-Term Equity Incentive Awards
The Company maintains the Waters Corporation 2020 Equity Incentive Plan (the “EIP”), pursuant to which it may grant equity awards to its employees and other service providers, including the NEOs. Multiple factors, considered collectively, are reviewed by the Compensation Committee in determining the overall equity value to award each NEO. These factors include, without limitation, competitive market data, dilution, stock compensation expense, the financial and operational performance of the Company, each NEO’s individual performance, each NEO’s potential for making contributions to future Company performance and the value of equity grants both individually to each NEO and in the aggregate to all NEOs. The Compensation Committee believes that it is important to provide meaningful reward and recognition opportunities to our NEOs that are performance-based and are intended to align with long-term value creation to our shareholders.
40

Table of Contents

Stock Options
It has been the long-standing practice of the Compensation Committee to utilize
non-qualified
stock options to align the interests of our NEOs and other executives with those of our shareholders. We continue to believe that stock options provide strong alignment between shareholders and our NEOs because the value of a stock option is directly related to the stock price appreciation delivered to shareholders following the grant date of the option. If our stock price does not appreciate, the NEO will not realize any value with respect to the stock option.
Options granted to our NEOs are time-based and generally vest 20% annually over five years, subject to continued employment through each applicable vesting date.
Performance-Based Restricted Stock Units (PSUs)
The Compensation Committee grants PSUs to provide an equity-based award tied to a performance goal other than absolute increase in stock price. The Compensation Committee also believes that rTSR is an appropriate and effective metric to further tie compensation realized to performance.
The PSU awards granted to our NEOs in fiscal year 2024 are subject to performance-vesting based on the achievement of two specified performance goals, rTSR and adjusted
non-GAAP
OCCRG over a three-year period, each weighted at 50%. The Compensation Committee believes OCCRG is a strong indicator of sustained innovation as it requires a strong new product pipeline to maintain ongoing three-year revenue growth. The three-year OCCRG metric is an adjusted
non-GAAP
financial metric that measures the change in net revenue between two periods, without taking into account the impact of foreign currency exchanges rates during the period and excluding the impact of acquisitions made within 12 months of the acquisition close date. PSU recipients can earn from 0 – 200% of the target number of PSUs granted based on the level of achievement of such performance goals.
The threshold, target and maximum performance goals are established on the grant date and based on the Company’s long-term strategic plan as of that date. These goals are intended to be challenging but achievable if Company performance is strong. The rTSR goals for the PSU awards granted to our NEOs in fiscal year 2024 are set forth below:

TSR Percentile Rank |  | Applicable Payout Percentage of Target for PSUs
= > 75 th Percentile |  | 200%
50 th Percentile |  | 100%
25 th Percentile |  | 50%
< 25 th Percentile |  | 0%

If the Company’s TSR is negative, in no event will more than 100% of the target number of shares subject to the rTSR-based portion of the PSU award be earned.
The number of shares earned subject to the adjusted
non-GAAP
OCCRG goal over a three-year performance period can range from 0% if minimum threshold performance is not achieved, 50% if minimum threshold performance is achieved, 100% if the target performance is achieved, and up to a maximum of 200% if maximum performance is achieved, with straight line interpolation between such performance levels. These goals are intended to be challenging but achievable if Company performance is strong.
In addition, our PSU awards have a post-vesting holding period on the shares received (after payment of tax) from any earned PSUs, which for the NEOs is one year (or two years for the CEO).

Table of Contents

Time-Based Restricted Stock Units (RSUs)
The Compensation Committee also grants RSUs from time to time, including to new hires and in connection with promotions and recognition. Commencing in fiscal year 2025, the Compensation Committee has determined to add RSUs to the mix of annual awards granted to our NEOs. We believe that RSUs serve an important function to align with shareholders, drive retention and increase their stock ownership.
2022 PSU Performance Results
The PSUs granted in February 2022 (which have a performance period that commenced in January 2022 and ended in December 2024) were eligible to vest in early fiscal year 2025 upon the Compensation Committee’s determination of the achievement of the applicable performance goals set forth in the award agreement. The metrics for these 2022 PSU awards were rTSR and OCCRG, weighted equally and measured over a three-year period. The performance goals required for payout under these 2022 PSU awards, as well as the actual payout results, are shown in the chart below.

Long-Term Equity Incentive Awards – Fiscal Year 2025
As discussed above, commencing in fiscal year 2025, the Compensation Committee elected to change the weightings and vehicles used in the long-term incentive grants, and determined to rebalance the mix of long-term incentive equity awards, as follows:

2024 LTIP |  |  |  | 2025 LTIP
50% Stock Options |  | 50% PSUs |  |  |  | 30% Stock Options |  | 15% RSUs |  | 55% PSUs
•  5-year vesting (20% per year) |  | •  3-year performance period |  |  |  | •  5-year vesting (20% per year) |  | •  5-year vesting (20% per year) |  | •  3-year performance period
•  Exercise price is equal to the closing price of Waters’ common stock on the grant date and have a ten-year term |  | •  50% based on rTSR against the S&P 500 Health Care Index •  50% based on 3-year organic constant currency revenue growth |  |  |  | •  Exercise price is equal to the closing price of Waters’ common stock on the grant date and have a ten-year term |  |  |  | •  50% based on rTSR against the S&P 500 Health Care Index •  50% based on 3-year organic constant currency revenue growth

Perquisites and Benefits
The Company generally does not offer any perquisites solely for the benefit of our NEOs. Our NEOs are eligible to participate in compensation and benefit plans that are generally offered to other employees, such as the Company’s 401(k) plan, Employee Stock Purchase Plan and health and insurance plans. Our NEOs are also eligible to participate in the Company’s 401(k) Restoration Plan that is available to all employees who meet certain minimum earnings eligibility criteria. This plan is described more fully below in the narrative that accompanies the
Non-Qualified
Deferred Compensation table in this Proxy Statement. From time to time, we provide relocation assistance to our executives in accordance with our executive relocation program.
Severance and Change of Control Arrangements
The Company provides severance protection to each of our NEOs pursuant to a Change of Control/Severance Agreement in the event that their employment is terminated by the Company without cause or they resign for good reason in connection with a change of control. Our severance and change of control protections are designed to ensure continuity of executive leadership in the event of a change of control of the Company, and to ensure the ability of executives to evaluate a potential change of control in the best interests of the Company and shareholders. For a description of the severance and change of control protections in our NEOs’ Change of Control/Severance Agreements, please see the “- Payments Upon Termination or Change of Control” section of this Proxy Statement.
The Company also provides Dr. Batra and Mr. Chaubal with certain severance protections pursuant to their employment agreement or offer letter, as applicable, in the event their employment is terminated by the Company other than for cause or if the executive resigns for good reason absent a Change of Control, as further described below in the “- Payments Upon Termination or Change of Control” section of this Proxy Statement.
Stock Ownership Guidelines
In order to closely align their interests with those of the Company’s shareholders, the Company has minimum stock ownership guidelines for our executive officers.

Position |  | Stock Ownership Guideline |  | Years to Achieve |
Chief Executive Officer |  | 5x Base Salary |  |  | 3 |
Other Executive Officers |  | 2x Base Salary |  |  | 5 |

43

Table of Contents

If an executive officer becomes
non-compliant
with the guidelines, he or she will have a period of twelve months to regain compliance with the guidelines. If, after such twelve-month period, the executive officer remains
non-compliant,
then 50% of the net
after-tax
profit from any subsequent stock option exercise must be retained in shares of common stock until compliance with the guidelines is achieved. Exceptions to these stock ownership guidelines may be considered by the Compensation Committee. For purposes of these guidelines, in addition to any direct ownership of shares of common stock by an executive officer, any shares of unvested RSUs and vested
“in-the-money”
stock options granted by the Company to such executives apply toward the satisfaction of the guidelines. Unvested PSUs are not applied toward the satisfaction of stock ownership guidelines.
Ms. Bennett and Mr. Chaubal joined the Company in April 2021 and May 2021, respectively, and have until 2026 to meet the requirements of the ownership guidelines. Mr. Carpio joined the Company in June 2024 and will have until 2029 to meet the requirements of the ownership guidelines. Dr. Batra has met the requirement of the ownership guidelines after the March 2024 vesting of the PSUs that were granted in February 2021. Ms. Bennett and Messrs. Carpio and Chaubal have not yet satisfied the requirements of the ownership guidelines but are each within their initial compliance periods as noted above.
Policies and Procedures Related to the Grant of Certain Equity Awards
The Company has established processes designed to ensure that the timing of any option grants and other similar awards to executive officers is not influenced by material nonpublic information (“MNPI”). Grants are generally made shortly after the issuance of an earnings release and the furnishing or filing of a Current Report on Form
8-K,
or the filing of a Quarterly Report on Form
10-Q
or an Annual Report on Form
10-K,
regardless of any upcoming announcements or events that could impact the Company’s share price.
The Compensation Committee does not take MNPI into account when determining the timing and terms of option awards. Further, the Company has not timed the disclosure of MNPI to affect the value of executive compensation.
The following table contains information required by Item 402(x)(2) of Regulation
S-K about
stock options granted to the NEOs in fiscal year 2024 during the period from four business days before to one business day after the filing of the Company’s Annual Report on Form
10-K,
the Company’s Quarterly Report on Form
10-Q,
or the Company’s Current Report on Form
8-K
that disclosed MNPI.

Named Executive Officer |  | Grant Date |  | Number of securities underlying the award |  | Exercise price of the award ($/Sh) |  | Grant date fair value of the award |  | Percentage change in the closing market price of the securities underlying the award between the trading day ending immediately prior to the disclosure of material nonpublic information and the trading day beginning immediately following the disclosure of material nonpublic information
Udit Batra, Ph.D. |  | 2/7/2024 |  | 34,285 |  | $323.54 |  | $4,375,109 |  | (0.4)%

Jianqing Y. Bennett |  | 2/7/2024 |  | 5,759 |  | $323.54 |  | $734,906 |  | (0.4)%

Recoupment Policy
In 2023, the Company adopted a mandatory clawback policy that complies with the NYSE’s clawback listing standards, Section 10D of the Exchange Act and the rules promulgated thereunder (the “Clawback Policy”). In the event that we are required to prepare an accounting restatement of our financial statements due to our material noncompliance with any financial reporting requirement under the securities laws, the Clawback Policy requires that covered executives must reimburse us, or forfeit, any excess incentive-based compensation “received” (as defined therein) by such covered executive during the three completed fiscal years immediately preceding the date on which we are required to prepare the restatement. Executives covered by the Clawback Policy include our current and former executive officers, as determined by the Compensation Committee in accordance with Section 10D of the Exchange Act and the NYSE listing standards, and such other senior executives or employees who may from time to time be deemed subject to the Clawback Policy by the Compensation Committee.
44

Table of Contents

Incentive-based compensation subject to the Clawback Policy includes any compensation that is granted, earned or vested based wholly or in part on the attainment of a financial reporting measure. The amount subject to recovery is the excess of the incentive-based compensation “received” based on the erroneous data over the incentive-based compensation that would have been “received” had it been based on the restated results and is computed without regard to any taxes paid. The Clawback Policy will only apply to incentive-based compensation “received” on or after October 2, 2023.
The Clawback Policy is available as Exhibit 97 to the Company’s Annual Report on Form
10-K
for the year ended December 31, 2024.
In October 2023, the Company also amended and restated its previous discretionary recoupment policy for cash incentive compensation paid to current or former executive officers of the Company. Under this amended and restated policy, if the Board (or an authorized committee thereof, such as the Compensation Committee) determines that (i) the cash incentive compensation paid to an executive officer was based on a misstatement of financial results or operating objectives directly arising from such executive officer’s misconduct, or (ii) an executive officer willfully violated an employment obligation, in each case, the Board (or a duly authorized committee thereof) may recover from the applicable executive officer any cash incentive compensation in an amount that it considers appropriate under the circumstances. This discretionary recoupment policy serves as a supplement to the
SEC-compliant
recoupment policy described above.
Tax Implications
Section 162(m) of the Internal Revenue Code generally limits the tax deduction available to public companies for annual compensation paid to the CEO and certain other NEOs in excess of $1 million. The Compensation Committee believes that its primary responsibility is to provide a compensation program that attracts, retains, and rewards the executive talent necessary for Waters’ success and meets the other objectives described above. Consequently, the Compensation Committee has and will continue to pay compensation that is not tax deductible, in whole or in part, or is otherwise limited as to tax deductibility.
COMPENSATION COMMITTEE REPORT
The information contained in this report shall not be deemed to be “soliciting material” or “filed” or incorporated by reference in future filings with the SEC, or subject to the liabilities of Section 18 of the Exchange Act, except to the extent that Waters specifically incorporates it by reference into a document filed under the Securities Act of 1933 or the Exchange Act.
The Compensation Committee has reviewed and discussed with management the Compensation Discussion and Analysis as required by Item 402(b) of Regulation
S-K
of the Exchange Act. Based on its review and these discussions, on March 29, 2025, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement.

(a) | Dr. Batra did not receive additional compensation for his service as a director in fiscal years 2024, 2023 or 2022.

(b) | Reflects the base salary earned by the NEO during the applicable fiscal year.

(c) | Reflects the cash sign-on bonus paid to Mr. Carpio in June 2024, which was paid to him in connection with his commencement of employment with the Company on June 24, 2024 pursuant to his offer letter. In the event that Mr. Carpio’s employment with the Company is terminated for cause or by him for good reason (each as defined in his offer letter) (i) prior to June 24, 2025, he will be required to repay 100% of such bonus to the Company within 30 days following such date of termination; or (ii) within the period commencing on June 24, 2025 and ending on June 24, 2026, he will be required to repay 50% of such bonus to the Company within 30 days following such date of termination.

(d) | Reflects the aggregate grant date fair value of the PSUs and/or RSUs granted to the NEO in the applicable fiscal year, in each case, as computed in accordance with FASB ASC Topic 718, excluding the effect of estimated forfeitures. The grant date fair value of the PSUs that are eligible to be earned based on rTSR was determined based on a Monte Carlo simulation model, which is based on the probable outcome of the performance conditions associated with such portion of the award, and includes a discount for the post-vesting holding period. The grant date fair value of the RSUs and the PSUs that are eligible to be earned based on three-year OCCRG was determined by multiplying the number of shares subject to the award (at target for the PSUs) by the closing price of Waters’ common stock on the date the award was granted, and includes a discount for the post-vesting holding period for PSUs. The assumptions used to calculate the foregoing amounts are disclosed in Note 13 to the Waters Corporation Annual Report on Form 10-K for the years ended December 31, 2024, 2023 and 2022, as applicable. The aggregate grant date fair value of the PSUs granted during fiscal year 2024, assuming achievement of the highest level of performance, was $8,903,020 for Dr. Batra, $2,242,478 for Mr. Chaubal and $1,569,416 for Ms. Bennett. The aggregate grant date fair value of the PSUs granted during fiscal year 2023, assuming achievement of the highest level of performance, was $7,650,386 for Dr. Batra, $2,048,392 for Mr. Chaubal and $1,505,634 for Ms. Bennett. The aggregate grant date fair value of the PSUs granted during fiscal year 2022, assuming achievement of the highest level of performance, was $6,089,786 for Dr. Batra, $1,896,008 for Mr. Chaubal and $1,496,852 for Ms. Bennett.

(a) | Reflects the range of potential payouts under the Company’s AIP for threshold, target and maximum performance for fiscal year 2024. The amount listed in the threshold column is equal to the threshold level payout based on the achievement of Company and individual performance goals (i.e., 25% of the applicable NEO’s target annual bonus). The amount listed in the maximum column is equal to the maximum level payout based on the achievement of Company and individual performance goals (i.e., 200% of the applicable NEO’s target annual bonus). Mr. Carpio’s annual bonus under the AIP for fiscal year 2024 was prorated based on his start date of June 24, 2024. For a description of the AIP, please refer to the section titled “— Compensation Discussion and Analysis — Elements of Executive Compensation — Annual Incentive” above.

(b) | Reflects the number of PSUs granted under the EIP to each of our NEOs (other than Mr. Carpio) in fiscal year 2024. These PSU grants are eligible to be earned based 50% on rTSR and 50% on three-year OCCRG. The PSUs based on rTSR are earned if the Company’s TSR meets or exceeds a specified level of TSR relative to the TSR for the companies included in the S&P 500 Health Care Index over a three-year performance period, generally subject to continued employment through the vesting date of the award. The PSUs based on three-year OCCRG are earned if the Company’s three-year compound annual growth rate meets or exceeds a specified level, generally subject to continued employment through the vesting date of the award. Amounts in the threshold column with respect to the PSUs reflect the number of PSUs that would be earned if threshold performance were achieved (in the case of PSUs based on rTSR, a TSR percentile rank above the 25th percentile, and in the case of PSUs based on three-year OCCRG, a revenue growth rate at or above the threshold goal), amounts in the target column (100% of the target award) reflect the number of PSUs that would be earned if target performance were achieved (in the case of PSUs based on rTSR, a TSR percentile rank of 50th percentile, and in the case of PSUs based on three-year OCCRG, a revenue growth rate of the target performance goal), and amounts in the maximum column (200% of the target award) reflect the number of PSUs that would be earned if maximum performance were achieved (in the case of PSUs based on rTSR, a TSR percentile rank of 75th percentile or greater, and in the case of PSUs based on three-year OCCRG, a revenue growth rate above the maximum goal). The number of PSUs earned under each metric is interpolated between threshold, target, and maximum performance levels.

(c) | Reflects the number of RSUs granted under the EIP to Mr. Carpio upon the commencement of his employment (i.e., June 24, 2024). These RSU awards vest 20% annually on the first five anniversaries of the date of grant, subject to continued employment through the applicable vesting date.

(e) | Reflects the closing price of a share of our common stock on the grant date of the stock option.

(f) | Reflects the aggregate grant date fair value of the stock award or option award granted to the NEO in fiscal year 2024, as computed in accordance with FASB ASC Topic 718, excluding the effect of estimated forfeitures. Amounts shown in this column, with respect to PSUs that are eligible to be earned based on rTSR, were determined based on a Monte Carlo simulation model, which is based on the probable outcome of the performance conditions associated with such portion of the award, and includes a discount for the post-vesting holding period. The grant date fair value of the PSUs that are eligible to be earned based on three-year OCCRG was determined by multiplying the number of shares subject to the award (at target) by the closing price of Waters’ common stock on the date the award was granted and includes a discount for the post-vesting holding period. The assumptions used to calculate these amounts are disclosed in Note 13 to the Annual Report.

##### Table of Contents

(d) | The aggregate balance amounts under the Company’s 401(k) Restoration Plan include deferrals made for prior years. For individuals who were NEOs in the years in which the deferrals were made, the amount of the deferred compensation was included in such individuals’ compensation as reported in the Summary Compensation Table included in the proxy statement for the applicable year, as set forth in the table below:

All non-qualified deferred compensation contributions made by the NEOs, or by the Company on behalf of the NEOs, are made under the Company’s 401(k) Restoration Plan. The purpose of the Company’s 401(k) Restoration Plan is to allow certain executives and highly compensated employees to defer salary, commissions, and bonus payments to a non-qualified retirement plan, in addition to the amount permitted to be deferred under the Company’s 401(k) Plan ($23,000 in 2024, or $30,500 if age 50 or older). The Company’s 401(k) Restoration Plan is also intended to permit participants to receive the additional matching contributions that they would have been eligible to receive under the Company’s 401(k) Plan if the Internal Revenue Service limits on compensation for such plan ($345,000 in 2024) did not apply. Upon termination of employment or retirement from the Company, account balances are distributed according to the payment option and form of payment (e.g., lump sum or installment payments) elected by the participant at time of deferral.

If, in connection with a change of control, the earned PSUs are not assumed or continued, or a new award is not substituted for the earned PSUs, the earned PSUs will automatically vest in full at target.

If, the employment of a NEO terminates during the performance period of the PSUs due to the NEO’s death, or the NEO’s retirement, the PSUs will remain eligible to vest based on actual performance and, to the extent vested, will be settled at the end of the performance period or, if earlier, on a change of control, prorated for the number of days within the performance period as of the date of termination. Retirement means a termination of employment (other than for cause or at a time when cause exists) at any time the executive has reached age 60 with 10 years of service with the intention of concluding his or her working or professional career. As of December 31, 2024, none of our NEOs have satisfied the age and service conditions under the Retirement definition.

Other Terms

For purposes of the NEOs’ Change of Control/Severance Agreements, “change of control” generally refers to the closing of a merger, consolidation, liquidation, or reorganization of the Company after which the Company does not represent more than 50% of the resulting entity; the acquisition of more than 50% of the voting stock of the Company; or the sale of substantially all of the Company’s assets.

The NEOs’ Change of Control/Severance Agreements also provide that, in the event that a NEO is subject to an excise tax under Section 4999 of the Code, he or she will be entitled to the greater of the following amounts, determined on an after-tax basis: (1) all payments that would be payable, without regard to the excise tax imposed under Section 4999 of the Code (the “Transaction Payments”), or (2) the portion of such Transaction Payments that provides the NEO with the largest payment possible without the imposition of an excise tax under Section 4999 of the Code.

(a) | For Dr. Batra, represents two times annual base salary, two times target annual incentive bonus award, and the amount the Company would have paid in premiums under the life, health, and dental insurance plans for 24 months for Dr. Batra and his dependents. For Mr. Chaubal, represents one times annual base salary, one times target annual incentive bonus award, and the amount the Company would have paid in premiums under the life, health, and dental insurance plans for 12 months for Mr. Chaubal and his dependents. All such amounts were determined based on base salary, target annual incentive bonus opportunity and premium costs, as applicable, as in effect on December 31, 2024.

(b) | For Dr. Batra, represents three times annual base salary, three times target annual incentive bonus award, and the value of 36 months of benefits continuation for Dr. Batra. For Mr. Chaubal, Ms. Bennett and Mr. Carpio, represents two times annual base salary, two times target annual incentive bonus award, and the value of 24 months of benefits continuation for the applicable NEO. All such amounts were determined based on base salary, target annual incentive bonus opportunity and premium costs, as applicable, as in effect of December 31, 2024. Also includes the unvested balance of a qualified medical expense reimbursement plan that would become vested upon change of control.

(c) | Represents the approximate in-the-money value of 100% of the unvested portion of the applicable NEO’s stock options upon termination as it relates to a termination of employment in connection with a change in control or death or, solely for Dr. Batra, the in-the-money value of the unvested portion of his sign-on stock options in the event of an involuntary termination of employment by the Company without cause, by him for good reason, or by reason of his disability, pursuant to his employment agreement. These values were calculated by multiplying the number of stock options that would have vested upon such employment termination or change of control, as applicable, by the difference between $370.98, the closing price of our common stock on December 31, 2024, and the applicable per share exercise prices of such stock options.

(d) | Represents 100% of the unvested portion of the applicable NEO’s RSUs. These values were calculated by multiplying the number of RSUs that would have vested upon such employment termination or change of control, as applicable, by $370.98, the closing price of our common stock on December 31, 2024.

(e) | Represents the value of the applicable NEO’s unvested PSUs, assuming the target number of shares vested and became earned on December 31, 2024. These values were calculated by multiplying the target number of PSUs that would have become earned and vested upon such employment termination by $370.98, the closing price of our common stock on December 31, 2024, prorated for the number of days within the performance period as of December 31, 2024, in the case of a termination due to death. The actual amount that can be earned in respect of PSUs will be dependent on actual performance measured at the end of the performance period.

CEO PAY RATIO DISCLOSURE

In accordance with SEC rules, we are required to disclose the ratio of the median of the annual total compensation of all of our employees (other than the CEO) to the annual total compensation of our CEO. Under these rules, the median employee is only required to be identified once every three years if there have not been any changes in our employee population or compensation arrangements that we reasonably believe would significantly affect our pay ratio disclosure. After reviewing our employee population and compensation arrangements, we reasonably believe that there were no changes in fiscal year 2024 that would significantly affect our pay ratio disclosure and, therefore, we did not re-identify our median employee for fiscal year 2024.

To identify the median of the compensation of all of our employees (other than our CEO) in fiscal year 2023, we first identified our total employee population as of December 31, 2023, which consisted of 8,074 employees, of which 3,020 employees were located in the United States and 5,054 employees were located in non-U.S. jurisdictions. As permitted by SEC rules, we then excluded all employees (352 total) from the following countries/jurisdictions: Sweden (56), Australia (50), Austria (38), Denmark (33), Malaysia (28), Poland (25), Puerto Rico (21), Hungary (20), Czech Republic (18), Israel (18), Hong Kong (14), United Arab Emirates (11), Portugal (8), Finland (6) and Norway (6). After excluding these employees, our employee population for purposes of identifying the median employee consisted of 7,722 employees, of which 3,020 employees were located in the United States and 4,702 employees were located in non-U.S. jurisdictions. To identify the median of the compensation of all our employees (other than our CEO), we used total cash compensation, including fiscal year 2023 base salary and actual bonus paid in fiscal year 2023 in respect of fiscal 2022 performance, with salaries annualized for those permanent employees who did not work for the full year. Reasonable estimates of cash compensation were made for those employees who were hired during fiscal year 2023 using their fiscal year 2023 base salary and target bonus amounts. Compensation for non-U.S. employees was converted to U.S. dollars based on average fourth quarter foreign currency exchange rates.

With respect to our median employee, we then identified and calculated the elements of such employee’s compensation for fiscal year 2024 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K. With respect to the annual total compensation of our CEO, we used the amount reported in the “Total” column of our 2024 Summary Compensation Table in the Proxy Statement above. We determined that, for fiscal year 2024, (1) the median of the annual total compensation of all of our employees, other than our CEO, was $84,397, and (2) the 2024 annual total compensation of our CEO was $11,148,038. As a result, the estimated ratio of the annual total compensation of our CEO to the median of the annual total compensation of all employees (other than our CEO), was approximately 132-to-1.

This pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and the methodology described above.

Because the SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

PAY VERSUS PERFORMANCE
As discussed in the section “— Compensation of Directors and Executive Officers” above, our fiscal year 2024 performance-based compensation (target annual incentive award and grant date value of long-term equity incentives (assuming target performance for PSUs)) represented approximately 90% of the target total direct compensation for our principal executive officer, Dr. Batra, and approximately 78% of the target total direct compensation for all our other NEOs as a group. The table below summarizes the most important measures for determining NEO pay.

Most Important Measures for Determining Named Executive Officer Performance-Based Pay
Adjusted non-GAAP organic constant currency revenue growth (OCCRG)
Adjusted non-GAAP organic net income growth (ONIG)
Relative total shareholder return (rTSR)

Our variable compensation includes annual incentives based on achievement of OCCRG and ONIG performance goals. PSUs are based on rTSR and three-year OCCRG.
The Company has determined that ONIG is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table below) used by the Company in fiscal year 2024 to link executive compensation actually paid (“CAP”) to the Company’s NEOs to Company performance. ONIG promotes executive team alignment, focuses the executive team on operational efficiencies and profitable growth, provides a long-term perspective among executives and drives long-term shareholder value. ONIG is based on net income reported in accordance with GAAP, but adjusted to exclude certain charges and credits that the Company considers not directly related to ongoing operations or overall performance of the Company, and to exclude the impact of acquisitions made within twelve months of the acquisition close date.
The table below sets forth certain executive compensation and financial performance information required in accordance with SEC rules. CAP is calculated as prescribed under SEC rules and does not represent compensation in addition to what is disclosed under the section “— Compensation of Directors and Executive Officers” above.

The table below summarizes the reconciliation of compensation from the Summary Compensation Table above to compensation actually paid as calculated under SEC rules for fiscal year 2024. The valuation assumptions used to calculate the fair values of options, RSUs and PSUs include the stock price as of the applicable measuring date and, in the case of PSUs, the probable outcome of the performance conditions as of the applicable measuring date (or actual performance results approved by the Compensation Committee as of the applicable vesting date). Otherwise, the assumptions used to calculate fair values did not materially differ from those used in our disclosures of fair value as of the grant date. The Company does not have a pension plan or equity awards that vest in the same year they are granted.

Narrative Disclosure to the Compensation Actually Paid Table and the Reconciliation of Summary Compensation Table to Compensation Actually Paid Table
The cumulative total return of the Company’s common stock on December 31, 2024 as compared to December 31, 2019 was 158% as compared to 90% for the peer group presented for this purpose (the SIC Code 3826 Index – Laboratory Analytical Instruments).

Table of Contents

The following graph compares CAP to the Company’s TSR, the peer group TSR and GAAP and adjusted
non-GAAP
organic net income for the years ended December 31, 2024, 2023, 2022, 2021 and 2020.
Overall, the Company believes that the performance measures utilized in our incentive programs have appropriate alignment to the Company’s financial performance so that pay for performance incentivizes sustainable shareholder value creation.
The amount of CAP to Dr. Batra (and Mr. O’Connell, as applicable) and the average amount of CAP to the other NEOs as a group (excluding Dr. Batra and Mr. O’Connell) is generally aligned with the Company’s cumulative TSR over the five years presented in the table. CAP is significantly impacted by changes in our stock price due to the fact that long-term equity incentives generally comprise more than 50% of our annual target total direct compensation for NEOs and CAP includes the change in fair value for all equity awards that were outstanding and unvested at
year-end
or awards that vested during the year.
Non-qualified
stock options and RSUs granted to our NEOs generally vest over a period of five years, while PSUs vest after the three-year performance period; therefore, CAP for a given year may include up to five years of equity awards, depending on an executive officer’s tenure, awards granted and applicable vesting periods. Furthermore, CAP will increase over the years for executive officers that have joined the Company within the last five years, as in the case of our recent new leadership, because the number of equity grants with open vesting periods held by the executive officer will increase each year until he or she reaches the maximum number of annual grants that remain unvested. In addition, CAP will be lower when an executive officer forfeits equity awards on a termination of service, as in the case of Mr. O’Connell and Ms. Buck at the end of 2020 and Mr. Pratt in 2023. In general, CAP increases when the Company’s stock price increases as compared with the prior year end and decreases when the Company’s stock price decreases as compared with the prior year end.
The amount of CAP to Dr. Batra (and Mr. O’Connell, as applicable) and the average amount of CAP to the NEOs as a group (excluding Dr. Batra and Mr. O’Connell) is generally aligned with the Company’s net income over the five years presented in the table. The Company believes that net income growth drives shareholder value and, therefore, has included an adjusted
non-GAAP
organic net income metric (weighted 50%) under the AIP and has chosen this as the Company Selected Measure for 2024. AIP generally represents
12%-17%
of our annual target total direct compensation.

Narrative to Director Compensation Table

Following a review of market data, the Board determined for 2024 to keep cash compensation consistent with 2023, as described below.

For 2024, the annual cash retainer for each non-employee Director was $70,000, paid in quarterly installments, and a $1,500 fee for each Board and committee meeting attended. The annual Chairman cash retainer was $150,000 per year, paid in quarterly installments. The non-employee Chairman is eligible for both the annual cash retainer for non-employee Directors and the annual Chairman cash retainer, as well as additional committee chair retainers and committee fees. For 2024, the annual cash retainer for the Science and Technology Committee Chair was $10,000 and the annual cash retainers for the Audit and Finance Committee Chair, Compensation Committee Chair and the Nominating and Corporate Governance Committee Chair were each $15,000.

The 2024 annual Director equity awards were granted under the EIP to our non-employee Directors on the first business day in January 2024 and had a grant date fair value of approximately $220,000, with 50% of such annual award granted in the form of restricted stock and 50% of such annual award granted in the form of non-qualified stock options. The number of non-qualified stock options was determined based on the Black-Scholes value as of the date of grant. The per share exercise price of our non-employee Directors’ 2024 annual stock option awards was equal to the closing price of the Company’s common stock on the grant date ($328.62 per share). Both the restricted stock and non-qualified stock option awards granted to our non-employee Directors in 2024 have a one-year vesting term, subject to continued service through the applicable vesting date. In addition, the applicable award agreements provide for the acceleration of any unvested awards upon the death of a Director or in the event of a change of control.

Ms. Knight received an initial equity award upon her appointment to the Board in August 2024 (which was prorated to reflect her partial year of service), with 50% of such award granted in the form of restricted stock and 50% of such award granted in the form of non-qualified stock options. The number of non-qualified stock options was determined based on the Black-Scholes value on the date of grant. The per share exercise price of such stock option award was equal to the closing price of the Company’s common stock on the grant date ($336.49 per share). Both of Ms. Knight’s restricted stock and non-qualified stock option awards have a one-year

vesting term, subject to continued service through the applicable vesting date, and the applicable award agreements provide for acceleration of any unvested awards upon Ms. Knight’s death or in the event of a change of control.

All of our non-employee Directors are also reimbursed for expenses incurred in connection with their attendance at meetings. Directors who are full-time employees of the Company receive no additional compensation or benefits for service on the Board or its committees.

The Compensation Committee utilizes Pearl Meyer to provide advice on the structure of our non-employee Director compensation program. Pearl Meyer and the Compensation Committee utilize sources of data consistent with that used for the executive compensation assessment, which includes the industry peer group of 17 publicly traded companies described above in the Compensation Discussion and Analysis.

The Company also sponsors the 1996 Non-Employee Director Deferred Compensation Plan (the “Director Deferred Compensation Plan”), which provides non-employee Directors with the opportunity to defer 100% of retainer, meeting, and committee fees. Fees may be deferred to a cash-denominated account or invested in Company common stock units. If a Director elects to defer his or her fees in Company common stock units, the amount deferred is converted into common stock units by dividing the amount of fees payable by the average stock price of the Company’s common stock for the fiscal quarter. Fees deferred to a cash-denominated account are credited with an interest rate equal to the lesser of the Prime Rate plus 50 basis points or the maximum rate of interest that may be used without being treated as an “above market” interest rate under the SEC guidelines. In 2024, Ms. Knight, Mr. Jiang and Dr. Huang elected to defer fees into Company common stock units, and Mr. Kuebler elected to defer his fees to a cash-denominated account.

Stock Ownership Guidelines

In order to closely align their interests with those of the Company’s shareholders, the Company has minimum stock ownership guidelines for our Directors.

Position |  | Stock Ownership Guideline |  | Years to Achieve
Non-Employee Directors |  | 5x Annual Retainer |  | 5

If a Director becomes non-compliant with the guidelines, he or she will have a period of twelve months to regain compliance with the guidelines. If, after such twelve-month period, the Director remains non-compliant, then 50% of the net after-tax profit from any subsequent stock option exercise must be retained in shares of common stock until compliance with the guidelines is achieved. Exceptions to these stock ownership guidelines may be considered by the Compensation Committee. For purposes of these guidelines, in addition to any direct ownership of shares of common stock by a Director, any shares of unvested restricted stock, unvested RSUs and vested “in-the-money” stock options granted by the Company to such executives apply toward the satisfaction of the guidelines.

Dr. Huang and Mr. Jiang were appointed to the Board effective January and July 2021, respectively, and have until 2026 to meet the requirements of the ownership guidelines. Messrs. Brennan and Vergnano were appointed to the Board effective November 2022 and have until 2027 to meet the requirements of the ownership guidelines. Mr. Fearon was appointed to the Board effective March 2023 and has until 2028 to meet the requirements of the ownership guidelines. Ms. Knight was appointed to the Board effective August 2024 and has until 2029 to meet the requirements of the ownership guidelines.

Ms. Knight and Messrs. Brennan, Fearon, and Jiang have not yet satisfied the requirements of the ownership guidelines but are each within their initial compliance periods as noted above. Our other Directors, Ms. Baddour, Drs. Huang and Ornskov and Messrs. Kuebler and Vergnano, have satisfied the requirements of the ownership guidelines.

PROPOSAL 4 — APPROVAL OF THE AMENDED AND RESTATED 2009 EMPLOYEE STOCK PURCHASE PLAN

We are asking our shareholders to approve the Waters Corporation Amended and Restated 2009 Employee Stock Purchase Plan (the “A&R ESPP”), which, if approved by our shareholders, will amend, supersede and replace the Waters Corporation 2009 Employee Stock Purchase Plan (the “Prior Plan”), except with respect to awards granted under the Prior Plan prior to the Effective Date (as defined below) of the A&R ESPP.

Overview

Upon the recommendation of the Compensation Committee, the Board adopted the A&R ESPP on February 5, 2025, subject to the approval of our shareholders at the Annual Meeting. The Board believes that adopting the A&R ESPP is in the best interests of the Company and its shareholders because it will provide our employees an opportunity to acquire a proprietary interest in the Company to promote the growth and success of the Company by aligning the interests of the A&R ESPP participants with those of the Company’s shareholders.

If the A&R ESPP is approved by our shareholders at the Annual Meeting, the A&R ESPP will become effective on the date of the Annual Meeting (such date, the “Effective Date”) and will supersede and replace the Prior Plan, except with respect to awards granted under the Prior Plan prior to the Effective Date. Following the Effective Date, new awards will be granted under the A&R ESPP, the Prior Plan will terminate with respect to new awards, and no new awards will be granted under the Prior Plan.

If the A&R ESPP is not approved by our shareholders at the Annual Meeting, the A&R ESPP will not become effective, and the Prior Plan will remain in effect until its termination, after which date no further awards may be granted under the Prior Plan. Whether or not the A&R ESPP is approved by our shareholders, each award granted under the Prior Plan prior to its expiration (or, if occurring earlier, its termination) will continue to be subject to the terms and provisions applicable to such award under the applicable award agreement and the Prior Plan.

If the A&R ESPP is approved by our shareholders, we intend to file, pursuant to the Securities Act, a registration statement on Form S-8 to register the additional shares of common stock to be made available under the A&R ESPP as soon as reasonably practicable thereafter.

The Prior Plan was adopted by the Board on February 27, 2009. Under the Prior Plan, an aggregate of 886,456 shares of common stock was authorized for issuance, which reflects the sum of (i) 750,000 shares of common stock, plus (ii) the number of shares of common stock reserved for issuance pursuant to the Company’s 1996 Employee Stock Purchase Plan but not issued thereunder as of January 1, 2009, subject to the applicable adjustment and share recycling provisions set forth in the Prior Plan.

If the A&R ESPP is approved by our shareholders, the aggregate number of shares of common stock that will be authorized for issuance under the A&R ESPP (the “Shares”) will be equal to the sum of (i) 750,000 Shares, plus (ii) the number of Shares reserved for issuance pursuant to the Prior Plan as of the Effective Date, subject to the applicable adjustment and share recycling provisions set forth in the A&R ESPP. As of the Record Date, there was an aggregate of 52,435 Shares remaining available for future issuance under the Prior Plan, which includes 9,952 Shares underlying options that were granted under the Prior Plan and exercised on March 31, 2025, in connection with the closing of the applicable offering period.

The last reported sale price of our common stock on the NYSE as of the close on the Record Date was $373.30 per share. For additional information regarding equity-based awards previously granted under the Prior Plan, please see Note 13 to our consolidated financial statements filed with our Form 10-K for the fiscal year ended December 31, 2024.

Summary of the Material Terms of the A&R ESPP

The following is a summary of the material terms of the A&R ESPP, and is qualified in its entirety by reference to the A&R ESPP included as Annex B to this proxy statement, which is incorporated by reference into this Proposal 4.

65

##### Table of Contents

The A&R ESPP provides an incentive to, and encourages stock ownership by, all eligible employees of the Company and its participating subsidiaries such that they may share in our growth by acquiring or increasing their share ownership in the Company. It is intended that the A&R ESPP constitute an “employee stock purchase plan” within the meaning of Section 423 of the Code.

If the A&R ESPP is approved by our shareholders, the aggregate number of Shares that will be authorized for issuance under the A&R ESPP will be equal to the sum of (i) 750,000 Shares, plus (ii) the number of Shares reserved for issuance pursuant to the Prior Plan as of the Effective Date, subject to the applicable adjustment provisions set forth in the A&R ESPP. If any option to purchase Shares granted under the A&R ESPP (or under the Prior Plan) expires, terminates or is cancelled for any reason without having been fully exercised, the Shares not purchased or received by the applicable participant will again be available for issuance under the A&R ESPP. Shares issued pursuant to the A&R ESPP may be either authorized but unissued shares or shares held by the Company in its treasury.

The A&R ESPP is administered by the Compensation Committee. The Compensation Committee has the discretion, subject to the provisions of the A&R ESPP, to make or to select the manner of making all determinations with respect to options granted under the A&R ESPP. Further, the Compensation Committee has complete authority to interpret the A&R ESPP, to prescribe, amend and rescind rules and regulations relating to it, and to make all other determinations necessary or advisable for the administration of the A&R ESPP.

Any individual who is an “employee” (within the meaning of Section 3401(c) of the Code) of the Company or a participating subsidiary may participate in the A&R ESPP. However, the following employees will not be eligible to receive a purchase right under the A&R ESPP: (i) an employee who would own, immediately after the grant of the option under the A&R ESPP, capital stock of the Company and/or hold outstanding options to purchase stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company, or (ii) if such option under the A&R ESPP would permit such employee to purchase stock under all employee stock purchase plans of the Company and its subsidiaries to accrue at a rate which exceeds $25,000 of the fair market value of such stock (determined on the basis of the fair market value of such stock on the date such option was granted) for each calendar year in which such option is outstanding at any time.

Further, the Compensation Committee may provide that the following employees are not eligible to participate in the A&R ESPP: (i) a highly compensated employee within the meaning of Section 423(b)(4)(D) of the Code; (ii) such employee has not met a service requirement designated by the Compensation Committee (which may not exceed 2 years); (iii) such employee’s customary employment is for 20 hours per week or less; (iv) such employee’s customary employment is for less than 5 months in any calendar year; or (v) such employee is a citizen or resident of a foreign jurisdiction and the grant of a purchase right under the A&R ESPP would be prohibited under the laws of such foreign jurisdiction. The foregoing exclusions will be applied in an identical manner under each plan period of the A&R ESPP to all employees.

As of the Record Date, the Company and its participating subsidiaries had 5,220 eligible employees.

The Compensation Committee may provide for special terms applicable to participants who are citizens or residents of a foreign jurisdiction or who are employed by a participating subsidiary outside of the United States, as the Compensation Committee may consider necessary or appropriate to accommodate differences in local law, tax policy or custom. Also, the Compensation Committee may approve such supplements, amendments, or restatements of the A&R ESPP as it may consider necessary or appropriate for such purposes, provided, that no such special terms, supplements, amendments or restatements will include any provisions that are inconsistent with the terms of the A&R ESPP unless the A&R ESPP could have been amended to eliminate such inconsistency without further approval by the Company’s shareholders. Without limiting the foregoing, the Compensation Committee is authorized to adopt rules and procedures with respect to foreign participants regarding the exclusion of particular subsidiaries from participation in the A&R ESPP, eligibility to participate, the definition of “Compensation” under the A&R ESPP, handling of payroll deductions or other contributions, payment of interest, conversion of local currency, data privacy security, payroll tax, withholding procedures, establishment of bank or trust accounts to hold payroll deductions or contributions.

##### Table of Contents

The A&R ESPP is implemented through a series of purchase periods called “plan periods” (a single purchase period may not exceed 27 months). Each plan period begins on the first business day of each January, April, July and October and ends on the last business day of the following March, June, September and December, respectively (however, the Committee may change the duration and/or frequency of plan periods). An eligible employee may become a participant under the A&R ESPP by completing an enrollment agreement on the form provided by the Company prior to the enrollment deadline for the applicable plan period. Participants under the A&R ESPP may elect to have payroll deductions taken from each payroll during the applicable plan period in an amount between 1% to 15% of such participant’s eligible compensation. Also, participants in the A&R ESPP may, on one occasion only during each plan period, reduce the rate of their payroll deductions to 0%.

Participants in the A&R ESPP will be granted an option on the commencement date of the applicable plan period, which will provide such participant with the right to purchase a number of Shares determined by dividing such participant’s accumulated contributions during such plan period by the applicable purchase price (with a maximum of 5,000 Shares per plan period). The purchase price with respect to a plan period under the A&R ESPP will be an amount equal to 90% of the fair market value of a Share on (i) the applicable plan period commencement date or (ii) the applicable plan period termination date, whichever is lower (however, the Compensation Committee may modify this purchase price, subject to Section 423 of the Code).

A participant in the A&R ESPP may withdraw all (but not less than all) of their payroll deductions credited to their account under the A&R ESPP at any time prior to each plan period termination date by giving written notice to the Company. All of such participant’s payroll deductions credited to their account will be paid to the participant promptly after receipt of such notice of withdrawal, and such participant’s option for the current plan period will automatically be terminated. A participant’s withdrawal from a plan period will not have any effect upon such individual’s eligibility to participate in a successive plan period under the A&R ESPP.

In the event of a dissolution or liquidation of the Company, the plan period then in progress will terminate. In the event of a Covered Transaction, as defined in the A&R ESPP (but excluding a dissolution of liquidation of the Company), each right to purchase stock under the A&R ESPP will be assumed, or an equivalent right will be substituted by, the surviving entity. In the event that the surviving entity refuses to assume each purchase right or to substitute an equivalent right, any ongoing offering period will be shortened such that participants’ rights to purchase stock under the A&R ESPP are exercised prior to the transaction, unless the employee has withdrawn.

The Committee has authority to interpret the A&R ESPP, to prescribe, amend and rescind rules and regulations relating to it and to make all other determinations necessary or advisable for the administration of it. However, approval of the Company’s shareholders will be required to amend the A&R ESPP to (i) increase the share reserve or (ii) change the A&R ESPP in any manner that would be considered an adoption of a new plan within the meaning of Treasury Regulations 1.423-2(c)(4). Further, the Compensation Committee may, without shareholder consent and without regard to if a participant’s rights under the A&R ESPP are adversely affected, change the plan periods, establish the exchange ratio applicable to non-U.S. currency, adjust payroll withholding for any delays or mistakes, establish reasonable waiting and adjustment periods, and establish such other limitations as the Compensation Committee determines in its sole discretion is advisable and consistent with the A&R ESPP.

The A&R ESPP will become effective on the date of its approval by the shareholders of the Company, provided that such approval is obtained within 12 months following the date of the approval and adoption of the A&R ESPP by the Board, which occurred on February 5, 2025. No rights may be granted under the A&R ESPP prior to the Effective Date. Following the Effective Date, the A&R ESPP will continue in effect until terminated by the Board in accordance with the terms of A&R ESPP.

Material U.S. Federal Income Tax Consequences

The following is a general summary under current law of the principal U.S. federal income tax consequences related to awards under the A&R ESPP. This summary deals with the general federal income tax principles that apply and is provided only for general information. Some kinds of taxes, such as state, local and foreign income taxes and federal employment taxes, are not discussed. This summary is not intended as tax advice to participants, who should consult their own tax advisors.

##### Table of Contents

The A&R ESPP is intended to qualify as an “employee stock purchase plan” under Section 423 of the Code. Under the Code, participants will not recognize taxable income, nor will the Company be entitled to a deduction, upon the purchase of Shares under the A&R ESPP. Participants will recognize taxable income upon the “disposition” of shares purchased under the A&R ESPP (in the manner described below). For this purpose, the term “disposition” is defined as a sale, exchange, gift or transfer of legal title. However, certain transfers of shares are not treated as dispositions, including, for example, transfers from a decedent to an estate, transfer by bequest or inheritance, transfers to joint ownership with a right of survivorship, certain exchanges of stock pursuant to corporate reorganizations, pledges or hypothecations.

If a participant holds Shares purchased under the A&R ESPP for at least (i) two years following the applicable Enrollment Date, and (ii) one year following the date such Shares are purchased upon exercise of the right to purchase Shares (the “Holding Period”), and if such participant remains an employee of the Company or a participating subsidiary at all times from the applicable Enrollment Date until at least three months prior to the exercise of such participant’s right to purchase Shares, the participant will be taxed at ordinary income rates in the year of sale of the Shares on an amount equal to the lesser of the excess of the fair market value of the Shares on the (a) applicable Enrollment Date over the purchase price, and (b) date of disposition or death over the purchase price. The remaining gain, if any, from the sale will be treated as a long-term capital gain. The Company will not be entitled to a deduction upon a participant’s acquisition of Shares under the A&R ESPP or a qualifying disposition of Shares purchased under the A&R ESPP that is made after the Holding Period.

To calculate a participant’s gain or loss on the sale of Shares purchased under the A&R ESPP, the amount realized from the sale must be reduced by the participant’s basis in such Shares (purchase price increased by ordinary income resulting from sale). If such basis exceeds the amount realized on a sale that is made after the Holding Period, the loss will be a long-term capital loss.

Any dividends paid with respect to Shares will be included in a participant’s income in the year received and will be subject to taxation.

If a participant sells Shares purchased under the A&R ESPP prior to the end of the Holding Period, the sale will be deemed a “disqualifying disposition,” and an amount equal to the excess of the fair market value of the Shares at the time of purchase over the purchase price will be treated as ordinary income. This amount will be included in the participant’s total taxable wages shown on the participant’s Form W-2 in the year of the disqualifying disposition. In addition, the Company will be entitled to take a deduction on its income tax return equal to the amount of such Participant’s ordinary income resulting from the sale.

Such Participant’s ordinary income recognized upon such “disqualifying disposition” is then added to the purchase price of the Shares for purposes of determining the basis of the Shares. The capital gain or loss on a sale of Shares is calculated by subtracting this basis from the amount realized on the sale. The capital gain or loss will either be long-term or short-term depending on the time period that the Shares are held. The capital gain or loss will be long-term provided that the Shares are held for more than one year. Otherwise, such amount will be treated as short-term capital gain, which is currently taxed in the same manner as ordinary income.

The Company or any participating subsidiary will be entitled to require payment in cash or deduction from other compensation payable to each participant of any sums required by federal, state or local tax law to be withheld with respect to any purchase of Shares under the A&R ESPP or any sale of such Shares.

THE DISCUSSION ABOVE IS INTENDED ONLY AS A SUMMARY AND DOES NOT PURPORT TO BE A COMPLETE DISCUSSION OF ALL POTENTIAL TAX EFFECTS RELEVANT TO RECIPIENTS OF AWARDS UNDER THE A&R ESPP. AMONG OTHER ITEMS THIS DISCUSSION DOES NOT ADDRESS ARE TAX CONSEQUENCES UNDER THE LAWS OF ANY STATE, LOCALITY OR FOREIGN JURISDICTION, OR ANY TAX TREATIES OR CONVENTIONS BETWEEN THE UNITED STATES AND FOREIGN JURISDICTIONS. THIS DISCUSSION IS BASED UPON CURRENT LAW AND INTERPRETATIONAL AUTHORITIES WHICH ARE SUBJECT TO CHANGE AT ANY TIME.

New Plan Benefits

Because the number of Shares that may be purchased under the A&R ESPP will depend on each employee’s voluntary election to participate and not withdraw from the A&R ESPP, the amount of payroll deductions elected

USER’S GUIDE

INFORMATION CONCERNING SOLICITATION AND VOTING

Date, Time, and Place of the Annual Meeting; Shareholder Questions

The Annual Meeting will be held on May 22, 2025 at 9:00 a.m., Eastern Time. The Annual Meeting will be a virtual meeting held exclusively via the Internet; you will not be able to attend the Annual Meeting in person. In order to attend and, potentially, to submit questions, you must register at www.proxydocs.com/wat. After you register, you will receive instructions via email, including your unique links that will allow you access to the Annual Meeting.

Our virtual Annual Meeting will allow shareholders to submit questions in two ways, both of which require that you be registered to attend the Annual Meeting. First, using your unique links provided at registration, shareholders may submit questions in advance of the Annual Meeting. Second, while viewing the Annual Meeting, shareholders may submit real-time questions via viewscreen.

During a designated question and answer period at the Annual Meeting, we will respond to appropriate questions submitted by shareholders. We will answer as many shareholder-submitted questions as time permits, and any questions that we are unable to address during the Annual Meeting will be answered following the meeting. If we receive substantially similar questions, we will group such questions together and provide a single response to avoid repetition.

We believe that hosting a virtual meeting is in the best interests of the Company and its shareholders and enables increased shareholder attendance and participation because shareholders can participate from any location around the world.

Solicitation

This Proxy Statement is being furnished by the Board in connection with its solicitation of Proxies for use at the Annual Meeting. Solicitation of Proxies, which is being made by the Board, may be made through officers and regular employees of the Company by telephone or by oral communications with shareholders following the original solicitation. No additional compensation will be paid to officers or regular employees for such Proxy solicitation. The Company has retained Alliance Advisors, LLC to conduct a broker solicitation for a fee of $16,500, plus reasonable out-of-pocket expenses. Expenses incurred in connection with the solicitation of Proxies will be borne by the Company.

Voting Matters

The representation in person or by Proxy of a majority of the outstanding shares of common stock of the Company, par value $0.01 per share (the “common stock”), entitled to vote at the Annual Meeting is necessary to provide a quorum for the transaction of business at the Annual Meeting. Shares can only be voted if a shareholder is present via web conference, has voted via the Internet or by telephone, or is represented by a properly signed Proxy. Each shareholder’s vote is very important. Whether or not you plan to attend the Annual Meeting via web conference, please vote over the Internet or by telephone or sign and promptly return the Proxy card, which requires no additional postage if mailed in the United States. All signed and returned Proxies will be counted towards establishing a quorum for the Annual Meeting, regardless of how the shares are voted.

Shares represented by Proxy will be voted in accordance with your instructions. You may specify how you want your shares to be voted by voting on the Internet, by telephone, or by marking the appropriate box on the Proxy card. If your Proxy card is signed and returned without specifying how you want your shares to be voted, your shares will be voted as recommended by the Board, or as the individuals named as Proxy holders deem advisable on all other matters as may properly come before the Annual Meeting. The Proxy will be voted at the Annual Meeting if the signer of the Proxy was a shareholder of record on March 24, 2025 (the “Record Date”).

Any shareholder voting by Proxy has the power to revoke the Proxy prior to its exercise either by voting electronically at the Annual Meeting, by executing a later-dated Proxy or by delivering a signed written notice of the revocation to the Company, c/o Secretary, at 34 Maple Street, Milford, MA 01757 before the Annual Meeting begins.

If you have Internet access, we encourage you to record your vote on the Internet. It is convenient for you, and it saves the Company significant postage and processing costs. In addition, when you vote via the Internet or by telephone prior to the Annual Meeting date, your vote is recorded immediately and there is no risk that postal delays will cause your vote to arrive late and therefore not be counted.

This will ensure the presence of a quorum at the Annual Meeting. Promptly voting your shares will save us the expense and extra work of additional solicitation.

ANNEX A

RECONCILIATION OF GAAP TO NON-GAAP FINANCIAL MEASURES

This proxy statement contains financial measures, such as constant currency growth rate, non-GAAP operating income and non-GAAP net income, among others, which are considered “non-GAAP” financial measures under applicable U.S. Securities and Exchange Commission rules and regulations. These non-GAAP financial measures should be considered supplemental to, and not a substitute for, financial information prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The Company’s definitions of these non-GAAP measures may differ from similarly titled measures used by others. The non-GAAP financial measures used in this proxy statement adjust for specified items that can be highly variable or difficult to predict. The Company generally uses these non-GAAP financial measures to facilitate management’s financial and operational decision-making, including determination of management incentive compensation. These non-GAAP financial measures reflect an additional way of viewing aspects of the Company’s operations that, when viewed with GAAP results and the reconciliations to corresponding GAAP financial measures, may provide a more complete understanding of factors and trends affecting the Company’s business. Because non-GAAP financial measures exclude the effect of items that will increase or decrease the Company’s reported results of operations, management strongly encourages investors to review the Company’s consolidated financial statements and publicly filed reports in their entirety. Reconciliations of the non-GAAP financial measures to the most directly comparable GAAP financial measures are included in the tables below.

(a) | The Company believes that referring to comparable constant currency growth rates is a useful way to evaluate the underlying performance of Waters Corporation’s revenue. Constant currency growth, a non-GAAP financial measure, measures the change in revenue between current and prior year periods, excluding the impact of foreign currency exchange rates during the current period.

Footnotes to the Operating Income and Net Income Reconciliations

(a) | The purchased intangibles amortization, a non-cash expense, was excluded to be consistent with how management evaluates the performance of its core business against historical operating results and the operating results of competitors over periods of time.

(b) | Restructuring costs and certain other items were excluded as the Company believes that the cost to consolidate operations, reduce overhead, and certain other income or expense items are not normal and do not represent future ongoing business expenses of a specific function or geographic location of the Company.

A-2

##### Table of Contents

(c) | Litigation settlement gains and provisions were excluded as these items are isolated, unpredictable and not expected to recur regularly.

(d) | In connection with the Wyatt acquisition, the Company started to recognize a two-year retention bonus obligation that is contingent upon the employee’s providing future service and continued employment with Waters. The Company believes that these costs are not normal and do not represent future ongoing business expenses.

(e) | ERP implementation and transformation costs represent costs related to the Company’s initiative to transition from its legacy enterprise resource planning (ERP) system to a new global ERP solution with a cloud-based infrastructure. These costs, which do not represent normal or future ongoing business expenses, are one-time, non-recurring costs related to the establishment of the new global ERP solution that were determined to be non-capitalizable in accordance with accounting standards.

(f) | Acquisition-related costs include all incremental expenses incurred, such as advisory, legal, accounting, tax, valuation, and other professional fees. The Company believes that these costs are not normal and do not represent future ongoing business expenses.

(g) | Acquired in-process research and development was excluded as it relates to the cost of a licensing arrangement for charge detection mass spectrometry that the Company believes is unusual and not indicative of its normal business operations.

(h) | The pension settlement and curtailment expenses associated with certain defined benefit pension plans were excluded as the Company believes these expenses are not indicative of normal operating costs.

(i) | The asset impairment, a non-cash expense, is a one-time charge related to the write-off of certain intangible assets and a contingent consideration liability that were both associated with a previous acquisition. The asset impairment was excluded as the Company does not believe these expenses are indicative of normal operating costs.

(j) | Certain income tax items were excluded as these non-cash expenses and benefits represent updates in management’s assessment of ongoing examinations, tax audit settlements, or other tax items that are not indicative of the Company’s normal or future income tax expense.

6. | Terms of Participation

6.1.Plan Periods. Each calendar year during the term of this Plan shall have four Plan Periods, beginning on the first day of each January, April, July and October for which a closing price for the Company Common Stock is available, and ending on the last day of the immediately following March, June, September and December for which a closing price for the Company Common Stock is available, respectively. Each such period is referred to herein as a “Plan Period.” Notwithstanding the foregoing, at any time and from time to time, the Committee may change the duration and/or the frequency of Plan Periods or suspend operation of the Plan with respect to Plan Periods not yet commenced.

6.2.Election to Participate and Plan Deductions.

(a) Shares shall be offered for purchase under the Plan through a series of successive, non-overlapping Plan Periods in accordance with Section 6.1 until such time as (i) the maximum number of Shares available for issuance under the Plan shall have been purchased or (ii) the Plan shall have been sooner terminated.

(b) An eligible Employee may become a Participating Employee in the Plan by completing an enrollment agreement on the form provided by the company and filing it with the Company prior to the Company’s enrollment deadline for the Plan Period in which such Employee desires to participate, unless a later time for filing the subscription agreement is set by the Committee for all eligible Employees with respect to a given Plan Period. The enrollment agreement shall set forth the percentage of the Employee’s Compensation (subject to Section 6.2(c) below) to be paid as Contributions pursuant to the Plan.

(c) A Participating Employee may elect to have payroll deductions taken from each payroll during any Plan Period in an amount not less than one percent (1%) and not more than fifteen percent (15%) (or such other percentages as the Committee may establish from time to time before any Plan Period Commencement Date) of such Participating Employee’s Compensation on each payroll date during the Plan Period. All payroll deductions made by a Participating Employee shall be credited to his or her account under the Plan. No interest shall accrue on Contributions to the Plan. A Participating Employee may not make any additional payments into such account.

##### Table of Contents

(d) Unless the Committee announces otherwise before the start of a particular Plan Period, an eligible Employee’s enrollment agreement in effect at the end of one Plan Period will remain in effect for each subsequent Plan Period.

(e) A Participating Employee may discontinue his or her participation in the Plan as provided in Section 6.8. In addition, a Participating Employee may, on one occasion only during each Plan Period, reduce the rate of his or her Contributions to zero percent (0%) with respect to the Plan Period by completing and filing with the Company a new enrollment agreement authorizing a change in the payroll deduction rate. Any such change in payroll deduction rate shall be effective as of the first payroll period following the date of filing of the new enrollment agreement, if the agreement is filed at least ten (10) business days prior to such period and, if not, as of the second following payroll period.

(f) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 5 herein, a Participating Employee’s Payroll Deductions may be decreased during any Plan Period to zero percent (0%). Payroll Deductions reduced to zero percent (0%) in compliance with this Section 6.2(f) shall re-commence automatically at the rate provided in such Participating Employee’s enrollment agreement at the beginning of the next Plan Period, unless terminated by the Participating Employee as provided in Section 6.8.

(g) Any amounts left over in a Participating Employee’s account upon expiration or termination of the Plan (or upon a withdrawal by a Participating Employee or upon a Participating Employee purchasing the maximum dollar amount or number of shares hereunder) shall be returned to the Participating Employee.

6.3.Foreign Employees. To facilitate participation in this Plan, the Committee may provide for such special terms applicable to Participating Employees who are citizens or residents of a foreign jurisdiction or who are employed by a Covered Entity outside of the United States, as the Committee may consider necessary or appropriate to accommodate differences in local law, tax policy or custom. Such special terms may not be more favorable than the terms of rights granted under this Plan to eligible Employees who are residents of the United States, and must satisfy the requirements for rights to purchase Shares granted pursuant to an “employee stock purchase plan” that are set forth under Section 423 of the Code. Moreover, the Committee may approve such supplements to, or amendments, restatements, or alternative versions of, this Plan as it may consider necessary or appropriate for such purposes without thereby affecting the terms of this Plan as in effect for any other purpose. Notwithstanding the foregoing, no such special terms, supplements, amendments or restatements shall include any provisions that are inconsistent with the terms of this Plan as then in effect unless this Plan could have been amended to eliminate such inconsistency without further approval by the stockholders of the Company. Without limiting the foregoing, the Committee is specifically authorized to adopt rules and procedures, with respect to Participating Employees who are foreign nationals or employed in non-U.S. jurisdictions, regarding the exclusion of particular Subsidiaries from participation in the Plan, eligibility to participate, the definition of Compensation, handling of payroll deductions or other contributions by Participating Employees, payment of interest, conversion of local currency, data privacy security, payroll tax, withholding procedures, and/or establishment of bank or trust accounts to hold payroll deductions or contributions.

6.4.Shares.

(a) If the Committee determines that, on a given Plan Period Termination Date, the number of shares with respect to which options are to be exercised may exceed (i) the number of Shares that were available for sale under the Plan on the Plan Period Commencement Date, or (ii) the number of shares available for sale under the Plan on such Plan Period Termination Date, then the Company shall make a pro rata allocation of the Shares available for purchase on such Plan Period Termination Date in as uniform a matter as shall be practicable and as it shall determine in its sole discretion to be equitable among all Participating Employees exercising options to purchase Common Stock on such Plan Period Termination Date. The Company shall make pro rata allocation of the Shares available on the Plan Period Commencement Date pursuant to the preceding sentence, notwithstanding any authorization of additional Shares for issuance under the Plan by the Company’s stockholders subsequent to such Plan Period Commencement Date.

B-5

##### Table of Contents

(b) The Participating Employee shall have no interest or voting right in Shares covered by his or her option until such option has been exercised.

(c) Shares to be delivered to a Participating Employee under the Plan will be registered in the name of the Participating Employee.

6.5.Grant of Options.

(a) A Participating Employee shall be granted a separate purchase right for each Plan Period in which he or she participates.

(b) The number of Shares purchasable by a Participating Employee on each Plan Period Termination Date during the Plan Period, pursuant to Section 6.6 below, shall be determined by dividing such Employee’s Contributions accumulated during such Plan Period prior to such Plan Period Termination Date and retained in the Participating Employee’s account as of the Plan Period Termination Date by the applicable Purchase Price. However, the maximum number of Shares a Participating Employee may purchase during each Plan Period shall be five thousand (5,000) Shares, and provided further that such purchase shall be subject to the limitations set forth in Sections 6.2(c).

(c) The fair market value of the Shares on a given date (the “Fair Market Value”) means the value of a share of common stock on a particular date determined by such methods or procedures as may be established by the Committee. Unless otherwise determined by the Committee, the Fair Market Value of the common stock as of any date, is the closing price for the common stock as reported by the New York Stock Exchange (or on any other national securities exchange on which the common stock is then listed) for that date.

6.6.Exercise. Unless a Participating Employee withdraws from the Plan as provided in Section 6.8, each purchase right shall be automatically exercised on each Plan Period Termination Date, and Shares shall accordingly be purchased on behalf of each Participating Employee on each such Plan Period Termination Date. The purchase shall be effected by applying the Participating Employee’s Payroll Deductions for the Plan Period ending on such Plan Period Termination Date to the purchase of Shares (subject to the limitation on the maximum number of Shares purchasable per Participating Employee on any one Plan Period Termination Date) at the Purchase Price in effect for the Participating Employee for that Plan Period Termination Date. The Shares purchased upon exercise of an option hereunder shall be deemed to be transferred to the Participating Employee on the Plan Period Termination Date. During his or her lifetime, a Participating Employee’s option to purchase Shares hereunder is exercisable only by him or her.

6.7.Delivery. As soon as practicable after each Plan Period Termination Date, the Company shall arrange the delivery to each Participating Employee, as appropriate, of the Shares purchased upon exercise of his or her option.

6.8.Voluntary Withdrawal; Termination of Employment.

(a) A Participating Employee may withdraw all, but not less than all, of the Contributions credited to his or her account under the Plan at any time prior to each Plan Period Termination Date by giving written notice to the Company in accordance with the Company’s policy regarding withdrawal from the Plan. All of the Participating Employee’s Contributions credited to his or her account will be paid to him or her promptly after receipt of his or her notice of withdrawal and his or her option for the current Plan Period will be automatically terminated, and no further Contributions for the purchase of Shares will be made (or will be permitted to be made) during the Plan Period.

(b) Upon termination of the Participating Employee’s Continuous Status as an Employee prior to a Plan Period Termination Date for any reason, including retirement or death, the Contributions credited to his or her account will be returned to him or her or, in the case of his or her death, to the person or persons entitled thereto under Section 8, and his or her option will be automatically terminated.

B-6

##### Table of Contents

(c) A Participating Employee’s withdrawal during a Plan Period will not have any effect upon his or her eligibility to participate in a succeeding Plan Period or in any similar plan which may hereafter be adopted by the Company.

7. | No Special Service Rights

Nothing contained in this Plan shall confer upon any Employee any right with respect to the continuation of his or her employment with the Company or any Covered Entity or any other entity, corporation, partnership, limited liability company or business trust controlling, controlled by or under common control with the Company, or interfere in any way with the right of any such entity, subject to the terms of any separate employment agreement or provision of law or corporate articles or by-laws to the contrary, at any time to terminate such employment relationship or to increase or decrease, or otherwise adjust, the other terms and conditions of the Employee’s employment.

8. | Designation of Beneficiary

8.1. A Participating Employee may file a written designation of a beneficiary who is to receive any Shares and cash, if any, from the Participating Employee’s account under the Plan in the event of such Participating Employee’s death subsequent to the end of a Plan Period but prior to delivery to him or her of such Shares and cash. Any such beneficiary shall also be entitled to receive any cash from the Participating Employee’s account under the Plan in the event of such Participating Employee’s death during a Plan Period.

8.2. Such designation of beneficiary may be changed by the Participating Employee at any time by written notice. In the event of the death of a Participating Employee and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participating Employee’s death, the Company shall deliver such Shares and/or cash to the executor or administrator of the estate of the Participating Employee, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such Shares and/or cash to the spouse or to any one or more dependents or relatives of the Participating Employee, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.

9. | Transferability of Options and Shares

Neither Contributions credited to a Participating Employee’s account nor any rights with regard to the exercise of an option or to receive Shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution, or as provided in Section 8) by the Participating Employee. Any such attempt at assignment, transfer, pledge or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw funds in accordance with Section 6.8. In addition, if the Committee has so announced to Participating Employees at least five (5) days prior to the scheduled beginning of the next Plan Period, any Shares acquired on the Plan Period Termination Date of such Plan Period may be subject to restrictions specified by the Committee on the transfer of such Shares. Any Participating Employee selling or transferring any or all of his or her Shares purchased pursuant to the Plan must provide written notice of such sale or transfer to the Company within five (5) business days after the date of sale or transfer. Such notice to the Company shall include the gross sales price, if any, the Plan Period during which the Shares being sold were purchased by the Participating Employee, the number of Shares being sold or transferred and the date of sale or transfer.

B-7

##### Table of Contents

immediately prior calendar year, the amounts of Contributions, the per Share Purchase Price, the number of Shares purchased and the remaining cash balance, if any.

12. | Adjustments Upon Changes in Capitalization; Covered Transactions

12.1.Adjustment in General. All of the share numbers set forth in the Plan reflect the capital structure of the Company as of the date of the Board’s adoption of this Plan. If subsequent to that date the outstanding Shares (or any other securities covered by the Plan by reason of the prior application of this Section) are increased, decreased, or exchanged for a different number or kind of shares or other securities, or if additional shares or new or different shares or other securities are distributed with respect to Shares, as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar distribution with respect to such shares of Stock, an appropriate and proportionate adjustment will be made in (i) the maximum numbers and kinds of shares provided in Section 3, (ii) the numbers and kinds of shares or other securities subject to the then outstanding options, and (iii) the exercise price for each share or other unit of any other securities subject to then outstanding options.

12.2.Adjustment Upon the Occurrence of Certain Unusual or Nonrecurring Events. In the event of any corporate action not specifically covered by the preceding Section 12.1, including but not limited to an extraordinary cash distribution on Common Stock, a corporate separation or other reorganization or liquidation, the Committee may make such adjustment of outstanding options and their terms, if any, as it, in its sole discretion, may deem equitable and appropriate in the circumstances. The Committee may make adjustments in the terms and conditions of, and the criteria included in, options in recognition of unusual or nonrecurring events (including, without limitation, the events described in this Section) affecting the Company or the financial statements of the Company or of changes in applicable laws, regulations, or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan.

12.3.Related Matters. Any adjustment in Awards made pursuant to Section 12.1 or 12.2 shall be determined and made, if at all, by the Committee, acting in its sole discretion, and shall include any correlative modification of terms which the Committee may deem necessary or appropriate so as to ensure the rights of the Participating Employees in their respective options are not substantially diminished nor enlarged as a result of the adjustment and corporate action other than as expressly contemplated in this Section 12.

12.4.Covered Transactions. In the event of a Covered Transaction pursuant to Section 2.10(d), the Plan Period then in progress will terminate immediately prior to the consummation of such action, unless otherwise provided by the Committee. In the event of a Covered Transaction pursuant to Sections 2.10(a), (b) or (c), each option outstanding under the Plan shall be assumed or an equivalent option shall be substituted by the successor corporation or a parent or subsidiary of such successor corporation. In the event that the successor corporation refuses to assume or substitute for outstanding options, the Plan Period then in progress shall be shortened and a new Plan Period Termination Date shall be set (the “New Plan Period Termination Date”), as of which date the Plan Period then in progress will terminate. The New Plan Period Termination Date shall be on or before the date of consummation of the transaction and the Committee shall notify each Participating Employee in writing, at least ten (10) days prior to the New Plan Period Termination Date, that the Plan Period Termination Date for his or her option has been changed to the New Plan Period Termination Date and that his or her option will be exercised automatically on the New Plan Period Termination Date, unless prior to such date he or she has withdrawn from the Plan Period as provided in Section 6.8. For purposes of this Section 12.4, an option granted under the Plan shall be deemed to be assumed, without limitation, if, at the time of issuance of the stock or other consideration upon a Covered Transaction, each holder of an option under the Plan would be entitled to receive upon exercise of the option the same number and kind of shares of stock or the same amount of property, cash or securities as such holder would have been entitled to receive upon the occurrence of the transaction if the holder had been, immediately prior to the transaction, the holder of the number of Shares covered by the option at such time (after giving effect to any adjustments in the number of Shares covered by the option as provided for in this Section 12); provided, however that if the consideration received in the transaction is not solely common stock of the successor corporation or its parent (as defined in Section 424(e) of the Code), the Committee may, with the consent of the successor corporation, provide for the consideration to be received upon exercise of the option to

B-8

##### Table of Contents

be solely common stock of the successor corporation or its parent equal in fair market value to the per Share consideration received by holders of common stock in the transaction.

13. | Settlement of Awards

13.1.Violation of Law. Notwithstanding any other provision of the Plan to the contrary, if, at any time, in the reasonable opinion of the Company, the issuance of Shares pursuant to the Plan may constitute a violation of law, then the Company may delay such issuance of such Shares until (i) approval shall have been obtained from such governmental agencies, other than the Securities and Exchange Commission, as may be required under any applicable law, rule, or regulation and (ii) in the case where such issuance would constitute a violation of a law administered by or a regulation of the Securities and Exchange Commission, one of the following conditions shall have been satisfied:

(a) the Shares are, at the time of the issue of such Shares, effectively registered under the Securities Act of 1933; or

(b) the Company shall have determined, on such basis as it deems appropriate (including an opinion of counsel in form and substance satisfactory to the Company) that the sale, transfer, assignment, pledge, encumbrance or other disposition of such Shares or such beneficial interest, as the case may be, does not require registration under the Securities Act of 1933, as amended or any applicable State securities laws.

The Company shall make all reasonable efforts to bring about the occurrence of said events.

13.2.Corporate Restrictions on Rights in Stock. Any Shares to be issued pursuant to the Plan shall be subject to all restrictions upon the transfer thereof which may be now or hereafter imposed by the charter, certificate or articles, and by-laws, of the Company.

13.3.Investment Representations. The Company shall be under no obligation to issue any Shares unless the Shares to be issued pursuant to the Plan have been effectively registered under the Securities Act of 1933, as amended.

13.4.Placement of Legends; Stop Orders; etc. Each Share to be issued pursuant to the Plan may bear a reference to any applicable restriction under the Plan. All certificates for Shares or other securities delivered under the Plan shall be subject to such stock transfer orders and other restrictions as the Committee may deem advisable under the rules, regulations, and other requirements of any stock exchange upon which the Common Stock is then listed, and any applicable federal or state securities law, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.

14. | Covered Entities

The Board may, in its sole discretion, designate from time to time which Subsidiaries of the Company shall be “Covered Entities” under this Plan, which designation may be made without the approval of the stockholders of the Company. In addition, the Board may determine, in its sole discretion, that a Subsidiary that is a Covered Entity will cease to be a Covered Entity with respect to Plan Periods not yet commenced.
