  2. $0.5B

    We are singularly focused on bringing transformative medicines to people with serious diseases, and we are committed to operating our business responsibly and disclosing our progress to stakeholders on an annual basis. Our progress and efforts with respect to environmental, social, and governance topics, including community engagement and workplace practices, were recognized broadly in 2025. A selection of awards and recognitions include Forbes’ World’s Best Employers, Fortune 100 Best Companies to Work For® 2025, TIME 100 Most Influential Companies, Points of Light’s Civic 50, Science Magazine’s Top Employers, TIME Magazine’s Best Inventions of 2025 for JOURNAVX, U.S. News & World Report Best Companies to Work For and many others. Our corporate responsibility priorities relate to four objectives that are fundamental to our business: improving the lives of people with serious diseases; fostering a culture of innovation, integrity, and belonging; carefully managing our operations and environmental footprint; and making a positive impact in our communities. In 2025, our executive compensation program received substantial support, with approval by approximately 92% of the votes cast at the annual meeting. We believe this support is consistent with our shareholders’ understanding of our business model, our pay- for-performance compensation philosophy, and the long-term value we are creating. Our management development and compensation committee (“MDCC”) and our board of directors reviewed our compensation programs and made the following key decisions with respect to 2025 compensation: •We maintained the base salary and target cash bonus as a percentage of base salary for Dr. Reshma Kewalramani, our CEO and President. Based on a comparative analysis to companies in our peer group, we increased her target equity level to $14.5 million from $13.5 million. •We entered into a new employment agreement and new change of control agreement with Mr. Wagner in connection with his appointment as Chief Operating and Financial Officer. Under this new employment agreement, Mr. Wagner receives a base salary of $1 million, an increase from $950,000, and a target cash bonus of 100% of his base salary, an increase from his prior target of 90%. •We maintained the base salaries and target cash bonuses as a percentage of base salary for Dr. Carmen Bozic, Mr. Amit Sachdev, and Dr. Nia Tatsis. Based on a comparative analysis to companies in our peer group, we increased Mr. Wagner’s target equity level to $5.25 million from $4.75 million and the target equity level to $4.5 million from $4.0 million for our other executive vice presidents. •Our performance in 2025 resulted in the MDCC determining that we had achieved a Leading rating for 2025 (131 out of a total potential score of 150), with the payment of annual cash bonuses commensurate with this high level of performance. •Our total revenue exceeded the board’s pre-approved financial targets for 2025, resulting in above target (125%) payout achievement for our 2025 financial-based performance stock units (“PSUs”). In addition, the MDCC determined that our 2023 non-financial PSUs with a three-year performance period achieved maximum (200%) payout based on achieving all milestones associated with the award. •From 2020 through 2025, we maintained the mix of equity granted to our CEO and NEOs with 50% of each award consisting of PSUs that vest solely on the achievement of established performance goals and 50% consisting of time-based restricted stock units (“RSUs”). In connection with the increase in target equity levels, we increased the weight of the PSUs in the mix of equity for the February 2026 annual equity awards. This new equity mix results in more than 50% of the target equity levels consisting of PSUs that only vest upon the achievement of established performance goals with the remainder of the target equity levels consisting of time-based RSUs. This mix emphasizes company performance: specifically, financial strength, pipeline advancement and diversification, and manufacturing excellence. The updated mix of equity further strengthens the alignment of our compensation program with our pay-for-performance philosophy.

  3. Executive Transitions

    Executive Transitions Mr. Arbuckle, our former Chief Operating Officer, retired on July 1, 2025. In accordance with the usual practice of our compensation program, in February 2025, Mr. Arbuckle received a cash bonus based on his target of 100% of his base salary and received an equity grant based on his target equity level of $4.75 million. Upon his retirement, the MDCC determined that Mr. Arbuckle was eligible for the retirement vesting provisions of his equity awards.

    | Board Refreshment |

  8. NOMINEE TENURE

    Our board believes that board refreshment is integral to effective corporate governance. Our board seeks to balance continuity of experience with fresh perspectives and regularly considers refreshment. The CGNC is responsible for reviewing board composition, and developing membership criteria, and recommending director candidates to the board. The CGNC regularly reviews competencies, qualities, skills, and experiences with the goal of ensuring that its members reflect a wide range of viewpoints, experiences, and specific expertise. In assessing the qualifications of a candidate or nominee, the CGNC considers, among others: demonstrated leadership and strategic thinking in the biopharmaceutical industry or other industries; sound judgment; business, medical, or scientific expertise; the highest ethics and integrity; a commitment to the company’s success; and personal qualities that foster a respectful environment for engaged and constructive discussions. In connection with each incumbent director’s nomination recommendation, the CGNC also considers the overall mix of tenures on the board, a director’s age and length of service on the board, and each director’s performance and suitability. As part of our commitment to continued board refreshment, six of our eleven directors have joined our board since 2020, including five new independent directors.

    | Shareholder-Recommended Director Candidates |

  10. NOMINEE TENURE

    The CGNC will consider director candidates recommended by shareholders using the same criteria for director selection described above under Director Criteria, Qualifications and Experience. Shareholders recommending candidates for consideration should submit any pertinent information regarding the candidate, including biographical information and a statement by the proposed candidate that the candidate is willing to serve if nominated and elected, by mail to our corporate secretary at our offices at 50 Northern Avenue, Boston, Massachusetts 02210. If a shareholder wishes to nominate a candidate to be considered for election as a director at the 2027 annual meeting of shareholders using the procedures set forth in our by-laws, the shareholder must follow the procedures described in our by-laws and summarized in the section titled Other Information—Shareholder Proposals and Nominations for Director for the 2027 Annual Meeting on page 94 of this proxy statement. If a shareholder wishes to solicit proxies for a shareholder nominee for election to our board at the 2027 annual meeting of shareholders pursuant to Rule 14a-19 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the shareholder must follow the procedures set forth in Rule 14a-19 of the Exchange Act and our by-laws. Our by-laws provide for proxy access, a process that allows qualifying shareholders to nominate a director candidate for consideration at an annual meeting of shareholders and have such candidate be included in our proxy materials for the applicable shareholder meeting. The key elements of our proxy access by-law are as follows:

  11. NOMINEE TENURE

    | Provision | Requirement | | Ownership Threshold and Holding Period | Available to shareholders owning 3% or more of our voting shares continuously for at least 3 years. | | Number of Board Nominees | Total number of proxy access nominees is capped at the greater of 20% of the existing number of board seats (or the closest whole number below 20%) and two. | | Aggregation Limits | 20-shareholder limit on the number of shareholders who can aggregate their shares to satisfy the 3% ownership requirement. | | Proxy Fights | Proxy access nominees will not be included in the proxy materials if we receive notice that a shareholder intends to nominate a candidate who is not to be included in our proxy materials. | | Future Ineligibility | Proxy access nominees who fail to receive at least 10% of the votes cast “for” such nominee may not be re-nominated as a proxy access nominee for the next two annual meetings. |

  12. NOMINEE TENURE

  13. NOMINEE TENURE

    | Majority Votes Cast Standard |

  14. NOMINEE TENURE

    Our by-laws provide for a majority votes cast standard for uncontested elections of our directors. Under our by-laws, director nominees in an uncontested election who receive more votes cast “for” such director nominee than “against” such director nominee are elected. Our board’s policy is that any nominee for director in an uncontested election who receives a greater number of votes “against” than votes “for” the nominee’s election shall promptly tender their resignation to the chair of our board following certification of the shareholder vote. The CGNC will promptly consider the tendered resignation. Based on all factors it deems in its discretion to be relevant, the CGNC will recommend that our board either accept or reject the resignation and may recommend that the board adopt measures designed to address any issues perceived to underlie the election results. Our board will then act on the CGNC’s recommendation. We will promptly disclose our board’s decision, including, if applicable, the reasons for rejecting the tendered resignation. Any director whose resignation is being considered under this policy will not participate in the CGNC or board considerations, recommendations or actions with respect to the tendered resignation.

    CORPORATE GOVERNANCE AND RISK MANAGEMENT We are committed to good corporate governance and integrity in our business dealings. Our governance practices are documented in our Statement of Corporate Governance Principles, which addresses the role and composition of our board of directors and the functioning of the board and its committees. You can find our governance documents, including our Statement of Corporate Governance Principles, charters for each committee of the board, and our Code of Conduct, on our website www.vrtx.com under “Investors— Corporate Governance—Governance Documents.” Director Independence Our board of directors has determined that nine of our eleven director nominees qualify as “independent” under the definition of that term adopted by The Nasdaq Stock Market LLC (“Nasdaq”). Our independent director nominees are Dr. Bhatia, Mr. Carney, Dr. Garber, Mr. Lagarde, Ms. McKenzie, Mr. Sachs, Dr. Schneider, Ms. Thornberry, and Mr. Upadhyay. Our independent directors meet in executive session without management at each regularly scheduled board meeting. Each of the board committees is composed of independent directors. Board Leadership Structure Our board recognizes that one of its key responsibilities is to periodically evaluate the optimal leadership structure to ensure robust independent oversight of management and an engaged and effective board with complementary qualities, perspectives, and experiences. Given the dynamic and competitive environment in which we operate, the board believes that its optimal leadership structure may vary as circumstances warrant. The board values the flexibility to determine its optimal model for board leadership at any given time. As such, the board annually reviews its leadership structure and may choose a different leadership structure if circumstances should arise that lead it to believe that such structure would promote the long-term interests of our shareholders. Our governing documents permit the roles of Chair of the board and CEO to be filled by the same or different individuals. To ensure robust independent leadership on the board, our corporate governance guidelines also require our independent directors to elect a Lead Independent Director if the Chair of the board is a member of management or does not otherwise qualify as independent under the company’s director independence standards. Currently, the board believes it is in the best interests of the company and our shareholders for the roles of Chair of the board and CEO to be separated, supported by a Lead Independent Director who has oversight responsibilities. Separating these positions at this time allows our CEO to focus on strategic decisions and our day-to-day business operations and performance, allows the Chair, our former CEO, to drive organization and effectiveness of the board in addition to his specifically delineated executive responsibilities, and allows our Lead Independent Director to lead the board in its fundamental role of providing advice to and independent oversight of management, including promoting communication between management and our board and supporting our board’s oversight of risk and other key governance matters. The board believes that this structure provides our board with independent leadership, while providing the benefit of having our former CEO chair regular board meetings and our current CEO participate in regular board meetings as a director. The board annually evaluates whether combining or separating the roles of Chair of the board and CEO is in the best interests of the company and our shareholders. In its evaluation, the board considers a number of factors, including: (1) the individuals currently in the roles of CEO, Chair and Lead Independent Director and their record of leadership and performance in their roles; (2) the current composition of the board; (3) the effectiveness of the policies, practices, and people in place to help ensure strong, independent board oversight; (4) the company’s performance and the effect the leadership structure could have on its performance; (5) the board’s performance and the effect the leadership structure could have on the board’s performance; (6) the Chair and Lead Independent Director’s performance in their respective roles; and (7) the views of our shareholders. A change in any of these factors could lead the board to determine in the future that it is more appropriate to have a different board leadership structure. Any such changes to our board leadership structure would be communicated to our shareholders through our annual proxy statement and as otherwise required by law.

    CORPORATE GOVERNANCE AND RISK MANAGEMENT Executive Chair of the Board Executive Chair of the Board Since 2020, Dr. Leiden has served as our Executive Chairman. In this role, Dr. Leiden not only serves as the Chair of our board, but also continues to have executive responsibilities with our corporate business development function, our cell and genetic therapy programs, and our external communications and government affairs activities, as described below. The board believes this leadership structure is currently in the best interest of shareholders because Dr. Leiden, as a long-time executive of the company, has a vast knowledge and deep understanding of the company and its strategic plans, people, and operations. This company-specific experience, along with Dr. Leiden’s extensive knowledge of the industry and comparable organizations and broad involvement in drug discovery and development, as well as his distinguished tenure as Chair of the board since 2012 and wide-ranging experience in corporate governance and leadership, provide him with outstanding advising and oversight capabilities as Chair of the board. Dr. Leiden’s specific responsibilities include: •overseeing the corporate business development function; •providing guidance on our cell and genetic therapy programs; •supporting external communications, including with our shareholders; •assisting the CEO with specific government affairs activities; •collaborating with CGNC, the Lead Independent Director, and the CEO on the identification, evaluation, and recruitment of potential candidates for board membership and consideration of overall board composition; •collaborating with CGNC and the Lead Independent Director on the recommendation to the board of individual directors to serve as members and chairs of each board committee; •collaborating with CGNC and the Lead Independent Director on development and recommendation to the board of the annual self-evaluation process for the board and its committees; and •collaborating with CGNC and the Lead Independent Director on the oversight of the CEO succession planning process, including assistance in recruiting and identifying potential candidates for the CEO position. Lead Independent Director Our board believes that strong, independent board leadership is a critical aspect of effective corporate governance. Our corporate governance guidelines require that if the Chair is not an independent director, the independent directors shall elect a Lead Independent Director. Since December 2011, Mr. Sachs has served as our Lead Independent Director or Co-Lead Independent Director. Mr. Sachs’ extensive business leadership experience as a CEO, a venture capitalist, and a director of the company, combined with his financial expertise, strongly positions him to provide independent leadership of the board and its responsibility for identifying and assessing company risks and providing guidance on risk mitigation strategies. The board recognizes the importance of appointing a strong Lead Independent Director to maintain a counterbalancing structure to ensure that the board functions in an appropriately independent manner and to hold management accountable for our continued success. As such, the responsibilities of the Lead Independent Director are designed to ensure that our independent directors are empowered to provide robust guidance to, and oversight of, management. Our Lead Independent Director’s responsibilities include: •calling and leading regular and special meetings of the independent directors; •serving as a liaison between our management and independent directors; •facilitating discussion and open dialogue among the independent directors, including with respect to the consideration of company risks and risk mitigation strategies; •presiding at executive sessions of the independent directors; •reviewing the planned dates for regularly scheduled board meetings and the primary agenda items for each meeting, which allows the Lead Independent Director to provide input and direction with respect to the matters that come before the board, including risk matters; •providing board leadership if the Chair of the board or CEO may be (or may be perceived to be) in conflict with the best interests of the company and its shareholders; •representing the board in certain communications with shareholders when requested and as appropriate; •collaborating with CGNC, the Chair of the board, and the CEO on the identification, evaluation, and recruitment of potential candidates for board membership and consideration of overall board composition; •collaborating with CGNC and the Chair of the board on the recommendation to the board of individual directors to serve as members and chairs of each board committee;

    CORPORATE GOVERNANCE AND RISK MANAGEMENT Board Committees •collaborating with CGNC and the Chair of the board on development and recommendation to the board of an annual self-evaluation process for the board and its committees; and •collaborating with CGNC and the Chair of the board on the oversight of the CEO succession planning process, including assistance in recruiting and identifying potential candidates for the CEO position. We believe our board structure provides consistent and strong independent oversight of management, while also facilitating a collaborative and collegial environment for board deliberations and decision-making. Board Committees Our board of directors has established various committees, each of which has a written charter, to assist in discharging its duties: the audit and finance committee (“audit committee”), the CGNC, the MDCC, and the science and technology committee (“S&T committee”). Each member of the audit committee, CGNC, MDCC and S&T committee is an independent director as that term is defined by the applicable SEC and Nasdaq rules. The primary responsibilities of each of the committees are set forth below, and the committee memberships are provided in the table appearing on page 25 of this proxy statement. Each of the committees has the authority, as its members deem appropriate, to engage outside legal counsel or other experts or consultants to assist the committee in carrying out its responsibilities. Each board committee has the authority to delegate any of its responsibilities to one or more subcommittees comprised of at least one member of the committee to the extent deemed appropriate but subject always to the general oversight of the board.

As appropriate for the circumstances, our audit committee reviews and considers the related person’s interest in the related party transaction and such other factors as it deems appropriate. In 2025, we had one transaction considered to be a related party transaction pursuant to Item 404(a) of Regulation S-K: our Chief Operating and Financial Officer’s daughter is employed by the Company in a non-executive position and received approximately $155,000 in total compensation in 2025.

    CORPORATE GOVERNANCE AND RISK MANAGEMENT Risk Management Risk Management Our board oversees an enterprise-wide approach to risk management, which is designed to support execution of our strategy and achievement of our goals to improve long-term operational and financial performance and generate long-term value for our shareholders. Our board believes that a fundamental part of risk management is understanding the risks that we face, adopting appropriate controls and mitigation activities for such risks, monitoring these risks, and responding to emerging developments with respect to such risks. In performing its risk oversight responsibilities, the board relies, in part, upon the results and information gained through our annual Enterprise Risk Management (“ERM”) Program. The ERM Program is overseen by our Chief Risk Officer, who reports to our Chief Legal Officer, and is designed to identify key enterprise risks and ensure appropriate management of those risks. As part of our ERM Program, we obtain input from our senior management and relevant subject-matter experts, evaluate industry trends and benchmarks, and consult external advisors as appropriate to identify the risks associated with our business based on likelihood of occurrence and potential impact to the business, as well as root causes of those risks. The ERM Program also assigns members of management responsibility for implementing controls and mitigations to reduce the likelihood or impact of each risk. The identified risks and related controls and mitigations are actively monitored by the board and regularly reviewed with senior management. The board’s role in our risk management process also includes reviewing regular reports and updates from senior management on near-term, medium-term, and long-term risks to the company. The board reviews and discusses strategic, operational, financial, compliance, legal, social (e.g., human capital management), environmental, governance, cybersecurity, and other risks. The board also receives updates from management regarding various enterprise risks related to our research, development, and commercialization plans, such as the competitive environment, manufacturing capabilities, product safety and quality, and drug pricing and reimbursement. These activities enable the board to understand and assess our risk environment, risk management, and risk mitigation strategies. Near- and medium-term enterprise risks are afforded significant attention by the board. The board and its committees have the opportunity to provide input and direction as to the management of those risks in a variety of manners, including through the ERM Program review, regular operational and financial updates and review of development programs, regular updates from our Chief Legal Officer, internal audit updates, talent reviews and succession planning, updates on cyber-security, healthcare compliance updates, reviews of executive compensation, budget reviews, and reviews of significant transactions. Longer term risks are addressed by the board through the annual strategic planning process, during which the board discusses and reviews our long-term operating plans and overall corporate strategy. Other risks that do not rise to the level of enterprise risks also are regularly assessed, discussed, managed, and monitored, including discussion with the board, as appropriate. Cross-functional members of management, including from our finance, accounting, investor relations, legal, compliance, information security, facilities, corporate communications, manufacturing, and disease strategy teams, work to ensure that material incidents and risks, including matters relating to significant actual or threatened litigation, significant regulatory matters and other matters that may have material financial, legal, or reputational impacts on the company are timely reported to the board and senior management and disclosed to our shareholders, as appropriate. In addition, we disclose our significant environmental, social and governance progress, strategies, and commitments in our annual Corporate Responsibility Report. While the board has the ultimate oversight responsibility for risk management, the board also manages risk through the division of responsibility within its committee structure, with each board committee being responsible for overseeing risk within its area of focus.

    At each regular meeting, or more frequently as needed, the board receives and considers committee reports, and such reports may provide additional detail on risk management issues and management’s response. The board and each committee also have the authority, in their sole discretion, to consult with and retain outside advisors and experts in connection with performance of its duties and responsibilities. Such outside advisors and experts are retained on a regular basis to assist the board and its committees in evaluating, managing, and anticipating risks, and include external auditors, legal counsel, compensation consultants, and business consultants, as appropriate. We have also established robust standards of business conduct that apply to all employees globally and provides numerous methods for employees to elevate risk concerns directly to management or through anonymous channels. Code of Conduct We have adopted a Code of Conduct that applies to all of our directors and employees, including our CEO and chief financial and accounting officers. We routinely review our Code of Conduct and make updates, as necessary. Our Code of Conduct is available on our website www.vrtx.com under “Investors—Corporate Governance—Governance Documents.” Disclosure regarding any amendments to, or waivers from, provisions of the Code of Conduct that apply to our principal executive, financial or accounting officers, or controller or persons performing similar functions will be posted on our website or included in a Current Report on Form 8-K within four business days following the date of the amendment or waiver. Insider Trading Policy We have adopted insider trading policies and procedures governing the purchase, sale and/or other dispositions of our securities by directors, officers and employees, or the company itself, that are reasonably designed to promote compliance with insider trading laws, rules and regulations and any listing standards applicable to us. A copy of our Insider Trading Policy is incorporated by reference to our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

The per share fair market values of our common stock on each of those dates was $497.51, $469.34, $410.31 and $443.56.

    We have stock ownership guidelines for our non-employee directors pursuant to which our non-employee directors should, within five years of becoming subject to the guidelines, hold shares of (a) our common stock, (b) unvested restricted stock units, and/or (c) deferred stock units having a value of at least five times the annual cash retainer. Our stock ownership guidelines exclude unexercised stock options. As of March 16, 2026, each of our non-employee directors was in compliance with our stock ownership guidelines, and each of our non-employee directors satisfied the individual holding requirements.

    PROPOSAL NO. 3: ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION Our compensation program is designed to attract, retain, and motivate talented and experienced individuals across all areas of our business and to align the interests of our employees, including our executive officers, with the interests of our shareholders as we seek to create value through the discovery, development, and commercialization of transformative medicines. In 2025, our annual advisory vote on executive compensation received support from approximately 92% of the votes cast at the annual meeting of shareholders. We believe this support is consistent with our shareholders’ understanding of our business model, our pay-for- performance compensation philosophy, and the long-term value we are creating. We plan to continue a high level of shareholder engagement regarding our executive compensation program. Our focus is and continues to be maintaining the strong link between our compensation programs and our ability to continue to develop transformative medicines while delivering sustained company performance, with 90% of our NEO compensation linked to performance. Our board and MDCC routinely review our compensation programs and made the following key decisions with respect to 2025 compensation: •We maintained the base salary and target cash bonus as a percentage of base salary for Dr. Reshma Kewalramani, our CEO and President. Based on a comparative analysis to companies in our peer group, we increased her target equity level to $14.5 million from $13.5 million. •We entered into a new employment agreement and new change of control agreement with Mr. Wagner in connection with his appointment as Chief Operating and Financial Officer. Under this new employment agreement, Mr. Wagner receives a base salary of $1 million, an increase from $950,000, and a target cash bonus of 100% of his base salary, an increase from his prior target of 90%. •We maintained the base salaries and target cash bonuses as a percentage of base salary for Dr. Carmen Bozic, Mr. Amit Sachdev, and Dr. Nia Tatsis. Based on a comparative analysis to companies in our peer group, we increased Mr. Wagner’s target equity level to $5.25 million from $4.75 million and the target equity level to $4.5 million from $4.0 million for our other executive vice presidents. •Our performance in 2025 resulted in the MDCC determining that we had achieved a Leading rating for 2025 (131 out of a total potential score of 150), with the payment of annual cash bonuses commensurate with this high level of performance. •Our total revenue exceeded the board’s pre-approved financial targets for 2025, resulting in above target (125%) payout achievement for our 2025 financial-based PSUs. In addition, the MDCC determined that our 2023 non-financial PSUs with a three- year performance period, achieved maximum (200%) payout, as a result of achieving all three milestones associated with the award. •From 2020 through 2025, we maintained the mix of equity granted to our CEO and NEOs with 50% of each award consisting of PSUs that vest solely on the achievement of established performance goals and 50% consisting of time-based RSUs. In connection with the increase in target equity levels, we increased the weight of the PSUs in the mix of equity for the February 2026 annual equity awards. This new equity mix results in more than 50% of the target equity levels consisting of PSUs that vest upon the achievement of established performance goals with the remainder of the target equity levels consisting of time-based RSUs. This mix emphasizes company performance, specifically financial strength, pipeline advancement and diversification, and manufacturing excellence. The updated mix of equity further strengthens the alignment of our compensation program with our pay-for-performance philosophy. •Mr. Arbuckle, our former Chief Operating Officer, retired on July 1, 2025. In accordance with the usual practice of our compensation program, Mr. Arbuckle received cash bonus based on his target of 100% of his base salary and an equity grant based off his target equity level of $4.75 million in February 2025. Upon his retirement, the MDCC determined that Mr. Arbuckle was eligible for the retirement vesting provisions of his equity awards.

    (1) “Burn rate” is defined as the number of equity awards granted in a specific year divided by the basic weighted average number of shares outstanding during that year. (2) Average number of employees as of January 1st and December 31st. Key Provisions of the 2026 Plan The 2026 Plan includes a number of provisions designed to serve shareholders’ interests and facilitate effective corporate governance, including the following: •Fungible Shares. Options granted at fair market value on the grant date (which is defined under the 2026 Plan as the average of the highest and lowest quoted selling prices on such date), and any other awards, such as stock appreciation rights or SARs, that we may grant at a purchase price of 100% of the fair market value of a share of our common stock on the date of grant (defined in the same manner), count against the number of shares authorized under our 2026 Plan at a rate of one share for each share granted. Any restricted stock units, restricted stock or other “full value” awards granted under the 2026 Plan count against the number of shares authorized for issuance under our 2026 Plan at a rate of 1.66 shares for each share granted. •No Stock Option Re-pricing/Exchange. Except in connection with specific corporate transactions (including stock dividends, stock splits, consolidations, mergers, recapitalizations and reorganizations), the 2026 Plan does not permit, without obtaining shareholder approval, (i) the amendment of the terms of stock options or SARs to reduce the exercise price or base value of such awards, (ii) the cancellation of any outstanding stock option or SAR in exchange for stock options or SARs that have an exercise price or base value that is less than the exercise price or base value of the original stock options or SARs, or (iii) the cancellation of outstanding stock options or SARs that have an exercise price or base value greater than the fair market value of a share of stock on the date of such cancellation in exchange for cash or other consideration.

  93. Diana McKenzie

    PROPOSAL NO. 4: APPROVAL OF 2026 STOCK AND OPTION PLAN •Limits on Non-Employee Director Compensation in respect of Director Service. The 2026 Plan includes a limit on the total amount of compensation payable, whether in cash, shares, or a combination thereof, to each director for his or her service on the board in any calendar year, not including service in any other capacity. •No Liberal Share Recycling. Shares underlying stock options and other awards issued under the 2026 Plan will not be recycled into the share pool if they are withheld in payment of the exercise price of the award or to satisfy tax withholding obligations in respect of the award. •No Reload Awards. The 2026 Plan prohibits the grant of “reload” stock options or SARs. A “reload” stock option or SAR is an automatic grant of a stock option or SAR when a participant uses already-owned shares to exercise his or her stock option or SAR. •No Dividends on Unvested Awards. No dividends or dividend equivalents will be paid with respect to shares subject to stock options or SARs unless and until such awards have vested and been exercised in accordance with their terms. Any dividends or dividend equivalents paid with respect to shares underlying awards other than stock options or stock appreciation rights will be subject to the same vesting terms otherwise applicable to the award. Existing Plans As of February 27, 2026, options to purchase (i) an aggregate of 987,065 shares having a weighted-average exercise price of $175.64 per share and a weighted-average term before expiration of 2.63 years were outstanding under the 2013 Plan. Also, as of February 27, 2026, there were outstanding an aggregate of 2,609,521 unvested restricted stock units and 1,061,262 unvested performance-based restricted stock units (assuming maximum performance) granted under the 2013 Plan and no unvested shares of restricted stock and restricted stock units granted under the Amended and Restated 2006 Stock and Option Plan (the “2006 Plan”). As of this same date, there were outstanding purchase rights with respect to approximately 60,000 shares under our Employee Stock Purchase Plan (based on the closing price per share on February 27, 2026) and 909,353 shares remaining available for future issuance under this plan. The company no longer grants new awards under the 2006 Plan and, upon the approval of the 2026 Plan by shareholders, the company will no longer grant new awards under the 2013 Plan. Submission of the 2026 Plan We are submitting our 2026 Plan to our shareholders as required under applicable rules of Nasdaq and to ensure favorable federal income tax treatment under Section 422 of the Code, for any grants of incentive stock options that we may make under our 2026 Plan. Summary of the 2026 Plan The following is a summary of the material terms of the 2026 Plan. A copy of the 2026 Plan is attached as Appendix A to this Proxy Statement, and we urge shareholders to read it in its entirety. The following description of the material terms of the 2026 Plan is qualified in its entirety by reference to the full text of the 2026 Plan. Purpose. The purpose of the 2026 Plan is to advocate the interests of the company by providing for the grant to participants of stock and stock-based awards, as described below. Administration. The 2026 Plan is administered by the MDCC, except that the board may at any time act in the capacity of administrator. As used in the 2026 Plan and this Proposal, the term “Administrator” refers to the MDCC, the board or any of its authorized delegates, as applicable. The Administrator has the discretionary authority, subject only to the express provisions of the 2026 Plan, to, among other things, administer and interpret the 2026 Plan, determine eligibility for and grant awards, determine, modify, accelerate or waive the terms and conditions of any award, determine the form of settlement of awards, prescribe forms, rules and procedures relating to the 2026 Plan and awards and otherwise do all things necessary or desirable to carry out the purposes of the 2026 Plan. Determinations of the Administrator under the 2026 Plan will be conclusive and bind all persons. The Administrator may delegate certain of its powers under the 2026 Plan to one or more of its members or members of the board and, to the extent permitted by law, officers of the company, and may delegate to employees or other persons such ministerial tasks as it deems appropriate. Eligibility. Employees and directors of, and consultants and advisors to, the company and its affiliates are eligible to be granted awards under the 2026 Plan. As of February 27, 2026, we estimate that approximately 6,600 employees, and 25 consultants and advisors would be eligible to participate in the 2026 Plan. As provided under the tax rules governing incentive stock options (“ISOs”), any recipient of ISOs will be limited to employees of the company or certain affiliates. Authorized Shares. Subject to adjustment as described below, the maximum number of shares that may be delivered in satisfaction of awards under the 2026 Plan is (i) 6,400,000 shares, plus (ii)(A) the number of shares available for issuance under the 2013 Plan as of the date of adoption of the 2026 Plan (reduced by the number of shares, if any, subject to awards granted under the 2013 Plan between the date of adoption of the 2026 Plan and its approval by our shareholders), plus (B) the number of shares underlying awards under the 2013 Plan that on or after the date of adoption of the 2026 Plan expire or are terminated, surrendered or canceled without the delivery of any shares of Stock, or are forfeited or reacquired by the company, in accordance with the terms of such plan, including the

  94. Diana McKenzie

    PROPOSAL NO. 4: APPROVAL OF 2026 STOCK AND OPTION PLAN fungible share ratio set forth therein (the “Share Pool”). Up to the total number of shares from the Share Pool may be issued in satisfaction of ISOs. The following rules apply in respect of the Share Pool: •Each share subject to an award of stock options or SARs will reduce the Share Pool by one share and each share subject to any other award will reduce the Share Pool by 1.66 shares. •All shares withheld in payment of the exercise price or purchase price of an award or in satisfaction of tax withholding requirements will reduce the Share Pool. •Shares underlying awards that are settled in cash will not reduce the Share Pool. •Shares underlying awards that expire, become unexercisable, or terminate or that are forfeited to or repurchased by the company without the issuance of shares will not reduce the Share Pool. •Shares delivered under awards granted in substitution for awards of an acquired company that are converted, replaced, or adjusted in connection with the acquisition (“Substitute Awards”) will not reduce the Share Pool. •The Share Pool will not be increased by any shares delivered under the 2026 Plan that are subsequently repurchased using proceeds directly attributable to stock option exercises. Shares that may be delivered under the 2026 Plan may be authorized but unissued shares, treasury shares, or previously issued shares acquired by the company. The closing price of our common stock as reported on the Nasdaq Global Market on February 27, 2026 was $496.83 per share. Non-Employee Director Limits. The aggregate value of all compensation granted or paid to any of our non-employee directors with respect to any calendar year, including awards that may be granted under the 2026 Plan, for his or her services as a director during such calendar year, may not exceed $1,250,000 in the aggregate, calculating the value of any equity awards based on the grant date fair value and assuming a maximum payout. The foregoing limitation does not apply to any compensation granted or paid to a director for his or her services to the company or an affiliate other than as a director, including, without limitation, as a consultant, advisor or other service provider to the company or an affiliate. Types of Awards. The 2026 Plan provides for the grant of stock options (including incentive stock options (“ISOs”) and nonqualified stock options (“NSOs”)), stock appreciation rights (“SARs”), restricted stock, unrestricted stock, stock units (including restricted stock units), performance awards, and other awards that are convertible into or otherwise based on our common stock. Dividend equivalents may also be provided in connection with awards under the 2026 Plan, but dividends or dividend equivalents relating to an award that, at the dividend payment date, remain subject to a risk of forfeiture (whether service-based or performance-based) will be subject to the same risk of forfeiture that applies to the underlying award. No dividends or dividend equivalents will be payable with respect to stock options or SARs. •Stock Options and SARs. The Administrator may grant stock options, including NSOs and ISOs, and SARs. A stock option is a right entitling the holder to acquire shares upon payment of the applicable exercise price. A “SAR” is a right entitling the holder upon exercise to receive an amount (payable in cash or shares of equivalent value) equal to the excess of the fair market value of the shares subject to the right over the base value from which appreciation is measured. The exercise price of each stock option, and the base value of each SAR, granted under the 2026 Plan may not be less than 100% of the fair market value of the shares subject to such stock option or SAR on the date of grant (110% in the case of ISOs granted to certain employees), as defined as set forth above. Each stock option and SAR will have a maximum term that does not exceed ten years from the date of grant (or five years, in the case of ISOs granted to certain employees). •Restricted and Unrestricted Stock and Stock Units. The Administrator may grant awards of restricted stock, unrestricted stock, and stock units (including restricted stock units). A stock unit is an unfunded and unsecured promise, denominated in shares, to deliver shares or cash measured by the value of shares in the future, and a restricted stock unit is a stock unit that is subject to the satisfaction of specified service or performance vesting conditions. Restricted stock is subject to restrictions requiring that it be forfeited, redelivered, or offered for sale to us if specified performance or other vesting conditions are not satisfied. •Performance Awards. The Administrator may grant performance awards, which are awards subject to performance vesting conditions, which may include performance criteria. •Other Stock-Based Awards. The Administrator may grant other awards that are convertible into or otherwise based on shares, subject to such terms and conditions as are determined by the Administrator. •Substitute Awards. The Administrator may grant Substitute Awards, which may have terms and conditions that are inconsistent with the terms and conditions of the 2026 Plan. Vesting; Terms of Awards. The Administrator determines the terms of all awards granted under the 2026 Plan, including the time or times an award vests or becomes exercisable, the terms on which awards will remain exercisable, and the effect of termination of a participant’s employment or service on awards. The Administrator may at any time accelerate the vesting or exercisability of an award. No award will provide for automatic “reload” grants of a stock option or SAR.

  95. Diana McKenzie

    PROPOSAL NO. 4: APPROVAL OF 2026 STOCK AND OPTION PLAN No Repricing. Other than in connection with certain corporate transactions or changes to our capital structure, stock options and SARs granted under the 2026 Plan may not be amended to reduce the exercise price or base value of the stock option or SAR, cancelled and exchanged for stock options or SARs with an exercise price or base value that is less than the exercise price or base value of the original stock option or SAR, or cancelled when the exercise price or base value of the stock option or SAR is greater than the fair market value of a share on the date of such cancellation in exchange for cash or other consideration, in each case, without shareholder approval. Transferability of Awards. Except as the Administrator may otherwise determine, awards may not be transferred other than by will, by the laws of descent and distribution, or pursuant to a validly issued domestic relations order. In no event may any award be transferred for consideration to a third party. Effect of Certain Transactions. In the event of a consolidation, merger or similar transaction in which the company is not the surviving corporation or which results in the acquisition of all or substantially all of the company’s then outstanding common stock by a single person or entity or by a group of persons and/or entities acting in concert, the sale or transfer of all or substantially all of the company’s assets or common stock, a dissolution or liquidation of the company, or a change in control (as defined in the 2026 Plan), the Administrator may, with respect to outstanding awards, which treatment does not have to be the same for all awards, provide for: •The assumption, continuation or substitution of some or all awards or any portion of an award by the acquirer or surviving entity; •The cash payment in respect of some or all awards (or any portion thereof) equal to the difference between the fair market value of the shares subject to the awards and its exercise or base price, if any, on such terms and conditions as the Administrator determines; and/or •The acceleration of exercisability and/or delivery of shares, in full or in part. Except as the Administrator may otherwise determine, each award will automatically terminate or be forfeited immediately upon the consummation of the covered transaction; provided, however, that unless the Administrator provides for the assumption, continuation or substitution of awards, all outstanding awards shall become immediately and fully exercisable, any applicable vesting conditions shall be deemed satisfied, with any performance vesting conditions deemed to be satisfied in full, and any forfeiture restrictions shall be deemed to have lapsed, in each case as of immediately prior to the consummation of the covered transaction. Adjustment Provisions. In the event of a stock dividend, extraordinary cash dividend, stock split or combination of shares (including a reverse stock split), recapitalization, or other change in our capital structure, the Administrator will make appropriate adjustments to: the Share Pool; the number and kind of shares or securities subject to, and, if applicable, the exercise or purchase price (or base values) of, outstanding awards; and any other provisions affected by such event. Clawback. The Administrator may provide that outstanding awards and proceeds from the exercise or disposition of awards or stock acquired under awards will be subject to forfeiture and disgorgement to the company, with interest and other related earnings, if the participant violates any restrictive covenants by which the participant is bound or any applicable company policy that provides for such forfeiture, disgorgement or clawback, or to the extent required by law or applicable stock exchange listing standards and any related company policy. Effective Date, Amendments and Termination. The board adopted the 2026 Plan on March 27, 2026, subject to approval by our shareholders; upon such approval the 2026 Plan will become effective. No awards will be granted under the 2026 Plan after May 13, 2036. The Administrator may at any time or times amend the 2026 Plan or any outstanding award and may at any time terminate the 2026 Plan as to future grants. However, except as expressly provided in the 2026 Plan or the applicable award, the Administrator may not alter the terms of an award so as to materially and adversely affect a participant’s rights without the participant’s consent (unless the Administrator expressly reserved the right to do so in the 2026 Plan or at the time the award was granted). Any amendments to the 2026 Plan will be conditioned on shareholder approval to the extent required by law or applicable stock exchange requirements. Certain Federal Income Tax Consequences The following discussion summarizes certain federal income tax consequences associated with certain awards granted under the 2026 Plan under the law as in effect on the date of this Proxy Statement. The summary of federal income taxes does not purport to cover federal employment tax or other U.S. federal tax consequences that may be associated with the 2026 Plan, nor does it cover state, local or non-U.S. taxes. ISOs. In general, an optionee realizes no taxable income upon the grant or exercise of an ISO. However, the exercise of an ISO may result in an alternative minimum tax liability to the optionee. With certain exceptions, a disposition of shares purchased under an ISO within two years from the date of grant or within one year after exercise produces ordinary income to the optionee (and a deduction is generally available to the company) equal to the value of the shares at the time of exercise less the exercise price. Any additional gain recognized in the disposition is treated as a capital gain for which the company is not entitled to a deduction. If the optionee does not dispose of the shares until after the expiration of the holding periods, any gain or loss recognized upon a subsequent sale is treated as a long-term capital gain or loss for which the company is not entitled to a deduction.

  96. Diana McKenzie

    PROPOSAL NO. 4: APPROVAL OF 2026 STOCK AND OPTION PLAN NSOs. In general, in the case of a NSO, the optionee has no taxable income at the time of grant but realizes income in connection with exercise of the option in an amount equal to the excess (at the time of exercise) of the fair market value of the shares acquired upon exercise over the exercise price; a corresponding deduction is generally available to company. Upon a subsequent sale or exchange of the shares, any recognized gain or loss after the date of exercise is treated as capital gain or loss for which the company is not entitled to a deduction. In general, an ISO that is exercised by the optionee more than three months after termination of employment is treated as an NSO. ISOs are also treated as NSOs to the extent they first become exercisable by an individual in any calendar year for shares having a fair market value (determined as of the date of grant) in excess of $100,000. SARs. In general, the grant of a SAR does not itself result in taxable income, nor does taxable income result merely because a SAR becomes exercisable. In general, a participant who exercises a SAR for shares or receives payment in cancellation of a SAR will have ordinary income equal to the amount of any cash or the excess, if any, of the fair market value of the shares received on exercise over the base value from which appreciation is measured, as applicable, and a corresponding deduction is generally available to the company. Unrestricted Stock Awards. A participant who purchases or is awarded unrestricted stock generally has ordinary income equal to the excess of the fair market value of the shares at that time over the purchase price, if any, and a corresponding deduction is generally available to the company. Restricted Stock Awards. A participant who is awarded or purchases shares subject to a substantial risk of forfeiture generally does not have income until the risk of forfeiture lapses. When the risk of forfeiture lapses, the participant has ordinary income equal to the excess of the fair market value of the shares at that time over the purchase price, if any, and a corresponding deduction is generally available to the company. However, a participant may make an election under Section 83(b) of the Code (the “83(b) election”) to be taxed on restricted stock when it is acquired rather than later, when the substantial risk of forfeiture lapses. A participant who makes an effective 83(b) election will realize ordinary income equal to the fair market value of the shares as of the time of acquisition less any price paid for the shares. A corresponding deduction will generally be available to the company. If a participant makes an effective 83(b) election, no additional income results by reason of the lapsing of the restrictions. For purposes of determining capital gain or loss on a sale of shares awarded under the 2026 Plan, the holding period in the shares begins when the participant recognizes taxable income with respect to the transfer. The participant’s tax basis in the shares equals the amount paid for the shares plus any income realized with respect to the transfer. However, if a participant makes an effective 83(b) election and later forfeits the shares, the tax loss realized as a result of the forfeiture is limited to the excess of what the participant paid for the shares (if anything) over the amount (if any) realized in connection with the forfeiture. Restricted Stock Units. In general, the grant of a restricted stock unit does not itself result in taxable income. Instead, the participant is generally taxed upon vesting (and a corresponding deduction is generally available to the company), unless he or she has made a proper election to defer receipt of the shares (or cash if the award is cash settled) under Section 409A of the Code. If the shares delivered are restricted for tax purposes, the participant will instead be subject to the rules described above for restricted stock. Certain Change in Control Payments. Under Section 280G of the Code, the vesting or accelerated exercisability of options or the vesting and payments of other awards in connection with a change in control of the company may be required to be valued and taken into account in determining whether participants have received compensatory payments, contingent on the change in control, in excess of certain limits. If these limits are exceeded, a substantial portion of amounts payable to the participant, including income recognized by reason of the grant, vesting or exercise of awards under the 2026 Plan may be subject to an additional 20% federal tax and may not be deductible to the company.

    COMPENSATION DISCUSSION AND ANALYSIS Executive Summary •Long-Term Equity Program: –In 2025, based on a comparative analysis to companies in our peer group, we increased Dr. Kewalramani’s target equity level to $14.5 million from $13.5 million, Mr. Wagner’s target equity level to $5.25 million from $4.75 million and the target equity level to $4.5 million from $4.0 million for our other executive vice presidents. Target equity levels have not been increased since July 2022 for our CEO and since December 2019 for our other NEOs. –From 2020 through 2025, we maintained the mix of equity granted to our CEO and NEOs with 50% of each award consisting of PSUs that vest solely on the achievement of established performance goals and 50% consisting of time-based RSUs. In connection with the increase in target equity levels, we increased the weight of the PSUs in the mix of equity for the February 2026 annual equity awards. This new equity mix results in approximately 55% of the target equity levels consisting of PSUs that vest upon the achievement of established performance goals with the remainder of the target equity levels consisting of time-based RSUs. This mix emphasizes company performance, specifically financial strength, pipeline advancement and diversification, and manufacturing excellence. The number of RSUs and PSUs awarded may be adjusted to reflect an executive officer’s individual performance for the relevant performance period and consequently are considered by the company to be performance-linked awards. We maintain a performance-specific modifier range, as outlined under Annual Equity Awards on page 69 below. –We achieved all three goals established for the 2023 non-financial-based PSU award, and performance was above the target level of performance for the 2025 financial-based PSU award, resulting in a 200% payout and a 125% payout, respectively, for each of these awards in February 2026. In addition, with respect to the PSU award granted to Mr. Arbuckle in December 2022, the MDCC certified achievement of all three performance milestones resulting in a maximum (200%) payout. The performance milestones associated with this award were based on launching two transformational therapies in diseases areas outside of CF, CASGEVY and JOURNAVX, and expanding CF leadership. –Based on discussions in late 2025 and early 2026, the MDCC granted new awards of PSUs in early 2026, the value of which was based on our NEOs’ individual performance in 2025. The MDCC established the financial and non-financial metrics that will determine whether and to what extent these awards become earned and vested. 50% of the PSUs, which vest annually in installments over three years, are tied to annual product revenue goals, while the remaining 50%, which cliff vest after three years, are tied to specific clinical, research and manufacturing milestones over a three-year period. We believe that a robust shareholder outreach program is an important component of maintaining our strong corporate governance practices. We strive for a collaborative approach with shareholders to solicit and understand a variety of perspectives and interests, and our practice has been to engage with our shareholders regularly over the course of the year. In 2025, we solicited feedback from shareholders representing approximately 70% of our outstanding shares and discussed numerous topics of shareholder interest, including our business strategy, approach to R&D, human capital management, corporate governance, executive compensation, shareholder proposals, and environmental sustainability initiatives.

    COMPENSATION DISCUSSION AND ANALYSIS Detailed Discussion and Analysis Role of Compensation Consultant The MDCC (i) is directly responsible for the appointment and oversight of its compensation consultants, (ii) has the authority to determine the fees that we pay for services provided by such compensation consultants, and (iii) prior to engaging any compensation consultant, considers applicable factors potentially affecting the independence of the compensation consultant, including the factors set forth in Nasdaq Marketplace Rule 5605(d)(3). Annually, the MDCC engages an independent compensation consultant to conduct an analysis of our compensation program as a whole, as well as all elements of our executive officer compensation program compared to similar elements paid to similarly situated executives at companies in our Peer Group (as defined below) and to provide a written report and presentation of findings at the meeting of the MDCC that occurs in the summer each year. The compensation consultant also provides guidance on other matters that may arise from time to time and participates in regular discussions with the MDCC Chair, as requested. In 2025, the MDCC continued its engagement with Pearl Meyer as its independent compensation consultant. Pearl Meyer is compensated by the company for advice provided at the direction of the MDCC. The MDCC reviews Pearl Meyer’s independence in accordance with applicable Nasdaq and SEC rules. Based on this review, and other factors considered by the MDCC, the MDCC determined that Pearl Meyer’s work did not raise a conflict of interest. Use of Peer Group Companies In order to conduct a thorough assessment about the competitiveness of the elements of executive compensation that we provide to our NEOs, the MDCC considers information about the compensation practices of a representative group of companies with whom we compete for executive talent (our “Peer Group”). We conduct a detailed analysis to select companies for this Peer Group on the basis of similarity and complexity of business model. While revenue and industry are common peer selection criteria, we also use a mix of quantitative and qualitative factors in order to establish our peers for this purpose, including the following:

  105. Acute Pain

    It is unlikely that companies will meet all factors listed above; therefore, we look for companies meeting a majority of the criteria, although we place greater weight on companies focused on innovation and the importance of medicines to patients and society as we believe these are the key drivers of our business model. On a regular basis, we review and revise the list of companies with the goal of maintaining a group of comparators comprised of at least twelve companies. As a result of this analysis, and based on the criteria listed above, the MDCC approved the following comparator companies for 2025, which were the same comparator companies used since 2022, except for the removal of Seagen Inc. in 2024 due to its acquisition by Pfizer in 2023.

    COMPENSATION DISCUSSION AND ANALYSIS Detailed Discussion and Analysis Properties of Peer Group We believe, based on our discussions with major shareholders, that the Peer Group identified by the MDCC is consistent with our shareholders’ views of our relevant peers in the biotechnology industry. In addition, the Peer Group companies have some or all of the business model characteristics that we seek in comparator companies as set forth in the following table.

We do not solely benchmark to a particular level of compensation relative to compensation levels at the Peer Group companies, but rather assess compensation levels after considerable deliberation about where each executive should fall in comparison with executives with similar responsibilities at the Peer Group companies. The MDCC looks at Peer Group information to confirm that our compensation levels are competitive with those of the Peer Group companies and consistent with our compensation philosophy. In addition, the MDCC reviews broader industry specific executive compensation surveys published by AON/Radford, Mercer SIRS, and Willis Towers Watson, but does not make any material compensation decisions based on any particular company participants in such surveys.

    COMPENSATION DISCUSSION AND ANALYSIS Detailed Discussion and Analysis Due to the low representation of the chief operating officer role within the Peer Group, Pearl Meyer supplemented the Peer Group with broader life science industry companies for purposes of analyzing competitive compensation for this role. Pearl Meyer reviewed companies within the broader life sciences industry and included all companies with a chief operating officer or similar role and greater than $2 billion in revenues and greater than $10 billion market capitalization. The MDCC reviewed the compensation practices for the following broader life science industry companies when considering the compensation for Mr. Wagner’s chief operating officer responsibilities as well as Peer Group data for his chief financial officer responsibilities:

  111. Acute Pain

    Our practice is to target total direct compensation including base salary, target annual cash incentives, and target long-term incentive awards at market competitive levels depending upon the NEO’s responsibilities, expertise, and experience. At superior levels of performance, we aim for the design of our executive compensation program to result in actual total direct compensation at or above the seventy-fifth percentile of peer executive compensation. Each year we review the mix of elements of our executive compensation program to ensure they are appropriately designed in light of our goals to align the program with our business strategy, the competitive environment, and our shareholders’ interests. Our executive compensation program emphasizes a mix of long-term equity compensation awards to incentivize and reward those individuals who make the greatest contribution to company performance over time. For our NEOs, this means compensation is primarily in the form of equity and directly tied to changes in shareholder value over time. Effective for the equity awards granted in February 2026, we updated our mix of equity awards so that more than 50% of each award is comprised of PSUs and the remainder of each award is comprised of time-based RSUs. Compensation Program As shown in the following charts, our compensation program places significant weight on performance-based compensation, with 90% of our NEO compensation linked to performance or “at-risk” if performance is not achieved.

  112. Performance-Based Value-Based Program

    | Compensation Element | Performance Link | | Annual Cash Bonus | •Annual bonus dependent on both company and individual performance factors | | Equity Awards | •Grant date value of equity awards based on target award values varies by level with differentiation for individual performance •Value of shares granted based on target set by the MDCC, adjusted for individual performance ranging from 0% for below target individual performance, 100% at target individual performance, and up to 150% for above target individual performance | | PSU Awards | •50% of PSUs with a range of shares earned from 0% to 200% of target based on one-year financial metrics (to the extent earned, vesting in equal installments over a three-year period) •50% of PSUs with a range of shares earned from 0% to 200% of target based on three-year non-financial metrics (to the extent earned, cliff-vesting after three years) | | Time-Based RSUs | •Value of awards increases or decreases based on stock price over the three-year vesting period •We consider our time-vesting RSU awards to be performance-based awards because the target number of RSUs awarded may be adjusted based on the corresponding executive’s individual performance for the relevant performance period prior to grant as well as the resulting value dependent upon increases or decreases in our stock price over the three-year vesting period |

  113. Performance-Based Value-Based Program

    More specifically: •PSU Awards. Beginning with the February 2026 equity awards, our CEO and executive vice presidents (“EVPs”) receive approximately 55% of their annual equity compensation in the form of PSUs. Half of the number of PSUs awarded are eligible to vest based on the achievement of financial goals (“financial PSUs”) and the other half of the number of PSUs are eligible to vest based on the achievement of non-financial goals (“non-financial PSUs”). The potential shares earned pursuant to each of these PSU awards range from 0% to 200% of the target number of shares, with the number of shares actually issued determined by the achievement of established financial and non-financial performance goals. –Financial PSUs: The financial PSUs are earned subject to meeting one-year revenue goals and, if earned, vest in equal annual installments over a three-year period measured from the date of grant. –Non-Financial PSUs: The non-financial PSUs are earned subject to meeting clinical development, regulatory and manufacturing milestones over a three-year performance period and, if earned, cliff vest after three years. The MDCC selected revenue and clinical development, regulatory and manufacturing milestones as the performance goals applicable to the PSUs because the MDCC determined that these milestones are important, measurable metrics, the achievement of which would indicate successful execution toward our short- and long-term strategic objectives and build considerable shareholder value. •Time-based RSUs. Beginning with the February 2026 equity awards, our CEO and EVPs received approximately 45% of their annual equity compensation in the form of time-based RSUs that vest in equal annual installments over a three-year period measured from the date of grant. With approximately 55% of the annual long-term incentive award at risk pending successful execution of our financial and strategic objectives through the grant of PSUs, we believe that it is important to have the remaining percentage of the annual long-term equity award focused on retaining our key executive talent. As a result, we believe time-based RSUs encourage retention and focus on long-term value creation thereby aligning the interests of the holders of these awards with the interests of our shareholders. •Prior to the adjustment to our equity compensation mix for our February 2026 equity grants, our executive officers received 50% of the target equity level in PSUs, and 50% of the target equity level in time-vesting RSUs, as reflected in the Summary Compensation Table on page 76 of this proxy statement.

  114. Performance-Based Value-Based Program

    Rather than awarding standard annual merit increases, the MDCC recommends base salaries for our executive officers based on multiple factors, including an annual competitive market analysis on a position-by-position basis. The MDCC reviews a comparison of each executive’s prior year base salary to salaries reported for executives with similar responsibilities at Peer Group companies (as supplemented for Mr. Wagner, as described above). The MDCC does not solely benchmark to a particular level of compensation relative to compensation levels at the Peer Group companies. Instead, the MDCC’s judgment about where each executive should fall in comparison with executives with similar responsibilities at the Peer Group companies takes into account the executive’s general level of experience and capability, the significance of the executive’s job responsibilities to the achievement of our business strategy and company goals, and general performance over time, including demonstration of corporate values. On the basis of that information, including a review of compensation at Peer Group companies, and taking into consideration the executive’s base salary for the previous year or years, the MDCC approves an appropriate base salary for each executive officer other than the CEO and recommends an appropriate base salary for the CEO, subject to final approval by our independent directors. As a result, executive officer base salaries may be held constant from year to year. In 2025, we maintained the base salaries for Dr. Kewalramani, Dr. Bozic, Mr. Sachdev, and Dr. Tatsis, based on multiple factors, including past and expected future contributions, performance, experience, specific responsibilities relative to peer benchmarks, and competitive positioning within the Peer Group companies. Mr. Wagner received a base salary increase in connection with his appointment as Chief Operating and Financial Officer, effective July 1, 2025. Mr. Arbuckle retired from the company effective July 1, 2025. Prior to his retirement, his salary was $1,000,000, which was the same as his base salary in 2024.

  115. Performance-Based Value-Based Program

    The amounts for two of the principal elements of our executive compensation program - annual cash bonus and annual equity awards - are determined on the basis of annual company and individual performance ratings. Overview of Company Performance Rating & Achievement in 2025 At the beginning of each year, the MDCC, in consultation with our CEO, establishes company-wide goals for that year under our annual and long-term cash and equity awards. While our performance against these goals is the most important factor considered in assessing our corporate performance, the MDCC considers additional accomplishments and shortcomings and may increase or decrease the performance scores associated with these goals. The aggregate discretionary adjustment may not exceed 10% of the performance score and the total company score may not exceed 150. The MDCC discusses and analyzes the company’s performance, including specific performance factors and accomplishment of company goals, and ultimately approves the company’s annual performance rating. While the aggregate discretionary adjustment is capped and relatively small, the MDCC believes this element provides an important mechanism to recognize the impact of unplanned events on the business whether positive or negative. For 2025, the MDCC set company goals and assigned relative weights to such goals that reflected our operational, strategic, and financial objectives for the year and the importance of these goals in achieving short- and long-term growth and increasing profitability. Our marketed products and late-stage clinical programs goals were designed to incentivize increasing access to our medicines through approvals of new transformative medicines and therapies, label-expansions for our existing medicines, obtaining reimbursements, and successfully commercializing new products. Our manufacturing, innovation, quality and operations goals were designed to incentivize supply chain resilience, efficiency in delivery of our commercialized medicines and commercial manufacturing readiness for medicines and therapies in our pipeline. Our pipeline goals and our budgets were established with the expectation that we would invest with discipline in R&D and external innovation with the goal of developing additional transformative medicines. Our organizational development and capability goals were established to incentivize ongoing improvements to our organizational structure, processes, and systems. Our financial strength objectives were designed to promote disciplined management of financial resources while maintaining flexibility to invest appropriately in support of both short- and long-term strategic objectives. We believe this mix of goals provides an appropriate balance between our near- and long-term objectives and among commercial, pipeline, manufacturing, financial, and organizational development objectives.

  126. Additional Factors (accomplishments and/or shortcomings)

    Value-Based Guidelines for Annual NEO Equity Grants Under our compensation program, equity awards for our CEO and EVPs are calculated by multiplying the individual’s target equity award by his or her performance rating-based equity modifier based on a performance-specific modifier range, as outlined below. This performance-specific modifier range increases the performance sensitivity of the program by adding the flexibility to adjust the equity modifier to reflect individual performance and expected contributions, further aligning the interests of our CEO and EVPs with the interests of our shareholders. The target value and corresponding performance rating-based equity modifier ranges for our executive officers for the equity grants made in 2025 are set forth in the table below.

  127. Additional Factors (accomplishments and/or shortcomings)

    The CEO equity modifier range is narrower relative to the COO and EVP ranges in order to reflect the tighter distribution of equity award values among the peer CEO comparators. February 2025 Grants Based on 2024 Performance In February 2025, Dr. Kewalramani, Mr. Arbuckle, and our other EVPs received equity grants based on their target equity levels of $13.5 million, $4.75 million and $4.0 million, respectively. The mid-point of the performance factor range for Leading and highest performance factor for Leading Exemplary performance were selected based on award values approximating the 75th and mid upper quartile percentiles, respectively, of executives at our Peer Group companies. The number of shares granted pursuant to the time- vested RSU award and PSU award was based on the fair value of our common stock on the date of grant (with the number of shares subject to PSUs determined at target). February 2026 Grants Based on 2025 Performance Based on a comparative analysis of our Peer Group companies, as supplemented to address Mr. Wagner’s chief operating officer role, in 2025, we increased the target equity levels for Dr. Kewalramani to $14.5 million from $13.5 million, Mr. Wagner to $5.25 million from $4.75 million, and our other EVPs to $4.5 million from $4.0 million, and revised the mix for the equity compensation granted in 2026 so that approximately 55% of each award consists of PSUs that vest solely on the achievement of established performance goals and approximately 45% of each award consists of time-based RSUs. This mix emphasizes financial accomplishments, pipeline advancement and diversification, and manufacturing objectives, and places more emphasis on company performance, aligning with our pay-for-performance philosophy. In February 2026, the MDCC approved individual performance factors and equity awards for each NEO (other than our CEO) as set forth in the table below. In February 2026, based on the MDCC’s recommendation, our independent directors approved the individual performance factor and equity award for our CEO as set forth in the table below.

    COMPENSATION DISCUSSION AND ANALYSIS Detailed Discussion and Analysis Performance Units Results Table We annually grant one-year financial-based PSU awards and three-year non-financial based PSU awards. We believe the combination of the one-year financial and three-year non-financial PSUs provides an appropriate balance of near- and long-term incentives for our management team. Our near-term objective of growing our revenues complements our long-term strategic objectives to progress our clinical portfolio and obtain approvals for additional transformative medicines for serious diseases. The performance goal for the 2025 financial-based PSU was established in February 2025 based on 2025 net product revenues using budgeted foreign currency rates. The final performance multipliers for our 2025 financial-based PSU awards were determined by the MDCC and applied to the target units granted to determine the actual units earned and eligible to vest with a payout of 125% in February 2026. The following chart shows the pre-established financial goals and the actual results for the financial-based PSU awards granted in 2025:

    (1)Reflects certain pre-established foreign exchange-related adjustments. Consistent with our philosophy of aligning compensation with performance, for 2025, a year in which we exceeded our net product revenue expectations, the payout on our one-year financial PSU awards was achieved above target level. The performance goals for the 2023 non-financial PSUs were established in February 2023 and our performance against these goals was determined in the first quarter of 2026. There were three non-financial goals, and achievement of one goal would have resulted in a 50% payout, achievement of two goals would have resulted in a 100% payout and achievement of three goals would have resulted in a payout of 200%.

    The final performance multipliers for our 2023 non-financial PSUs were determined by the MDCC and applied to the target units granted to determine the actual units earned and eligible to vest with a payout of 200% in February 2026. Performance achievement for the 2024, 2025 and 2026 non-financial based PSU awards will be determined in the first quarter of 2027, 2028 and 2029, respectively, based on performance over the relevant three-year performance period. The non-financial goals contained in our three-year PSU awards for 2024, 2025 and 2026 are based on multiple clinical and regulatory milestones and are not disclosed for competitive reasons and because the relevant performance periods are ongoing. The PSU awards granted in 2025 and 2026 contain a fourth non-financial milestone related to manufacturing excellence. Mr. Arbuckle was granted a PSU award in December 2022 that was eligible to be earned based on launching two transformational therapies in diseases areas outside of CF, CASGEVY and JOURNAVX, and expanding CF leadership. In May 2025, the MDCC certified achievement of all three performance milestones resulting in a maximum (200%) payout and 37,622 PSUs earned under the award.

    Benefits Our executives are eligible to participate in all of our benefit plans and programs on the terms made generally available to our employees, including medical insurance, dental insurance, payment of life insurance premiums, disability coverage, equity programs, including eligibility for a career employment/retirement provision and participation in our employee stock purchase plan, and eligibility for matching contributions, subject to an annual $25,000 limit, to qualified charitable organizations pursuant to the Vertex Foundation Matching Gift Program. We have a defined contribution—a 401(k)—plan, in which all of our eligible employees, including our NEOs, may participate. We make matching contributions to the 401(k) plan. The formula for determining the amount of our matching contributions is the same for our NEOs as for our other employees (and the contributions are subject to the same statutory maximum), but the actual contributions made to the accounts of our NEOs generally are at the top end of the range, due to the executives’ higher salaries and correspondingly higher cash contribution levels. Other than the retirement provision under our equity program available to all employees, we do not provide any retirement benefits to our executive officers. In 2025, we began offering a supplemental primary care medical benefit to our executive vice presidents, including our CEO and NEOs, to facilitate comprehensive and convenient access to healthcare. This is a taxable benefit for which the company provides a tax gross-up. The total value of the benefit, including the tax gross-up, is included in All Other Compensation column of the Summary of Compensation Table. During 2025, as a result of increasing security risks for executives in our industry, we engaged an independent, third-party security firm to perform a security threat assessment for our CEO and Executive Chairman. Based on the findings of this assessment, we implemented a new aviation policy, approved by our board, which allows private aviation for business and personal travel for our CEO and Executive Chairman. Under the policy, family members are permitted to accompany our CEO and Executive Chairman on business and personal travel, and our other NEOs are permitted to use private aviation for business travel if authorized by the CEO or Chief Operating Officer (except with respect to his own travel). In addition, based on the security threat assessment, we provide personal security services during business and non-business related events, and additional security measures have been made available to our CEO and Executive Chairman, including private ground transportation and enhanced residential security. These benefits are intended to increase security and personal safety, which benefits the company and its shareholders. We believe these benefits will allow our executives to operate and conduct business in a safe and secure manner and are consistent with market practice. Personal use of private aviation and security services by the CEO or Executive Chairman is subject to taxation and disclosure. Our CEO, Executive Chairman, and each NEO are responsible for paying the income taxes due on the value of aviation and security services used for personal use and we do not provide any tax gross-up payments.

    COMPENSATION DISCUSSION AND ANALYSIS Detailed Discussion and Analysis Employment Agreements and Post-Termination Compensation and Benefits The initial compensation terms for newly hired members of our executive team are the result of negotiations between us, in consultation with the MDCC and our board of directors, and the executive being hired. In general, each newly hired executive team member enters into an employment agreement and a change of control agreement and is granted an equity award, and in some cases a cash sign-on bonus, reimbursement of moving expenses, and other benefits. We also enter into employment and change of control agreements with EVPs who are promoted to our executive team, on the basis of standard terms and conditions that have been recommended by our MDCC and approved by our board for such circumstances. We have entered into agreements providing for severance and change of control payments with each EVP on our executive team because we believe that they are a fair and effective way to allow our executives to maintain focus on our business in the face of market and other volatility in our industry. In general, each employment arrangement provides for cash severance and continuation of certain employee benefits in the event that an executive’s employment is terminated by us without cause or is terminated by the executive for good reason. We use a “double trigger” with respect to benefits that are to be provided in connection with a change of control. A change of control does not itself trigger benefits; rather, benefits are paid only if the employment of the executive is terminated by us other than for cause, death or disability, or by the executive for good reason, during a specified period before or after a change of control. We believe a “double trigger” benefit maximizes shareholder value because it prevents a windfall to executives in the event of a change of control in which the executive retains significant responsibility as defined in their individual agreement, while still providing our executives appropriate incentives to cooperate in negotiating any change of control transaction that may put their jobs at risk. We offer a company-wide program that provides for accelerated vesting of equity awards held by qualified retirement-eligible participants who retire (our “Career Employment Provision”). In 2024, the MDCC assessed our Career Employment Provision to review peer practices, ensure alignment with our philosophy of rewarding and incentivizing long-term service with the Company as well as to provide a competitive advantage to attract talent with significant industry experience and expertise. As a result of the review, the MDCC amended the Career Employment Provision effective for any newly hired employees on or after January 1, 2025. Under the legacy Career Employment Provision, equity awards granted, including those granted to our NEOs, contain a retirement vesting provision, under which a “legacy qualified” participant who retires under the terms of the provision will receive accelerated vesting of an additional number of shares underlying the award, equal to the sum of (x) 50% plus 10% for each year of service in excess of five full years of service multiplied by (y) the number of unvested shares subject to the award. A “legacy qualified” participant is a participant (1) who is at least age 55 and who was most recently hired before January 1, 2025, (2) has completed at least five full years of service, (3) whose age plus full years of service is 65 or greater, and (4) who has completed a mandatory transitional period of employment with the company following notice of their planned termination of service. Under the amended Career Employment Provision, equity awards granted contain a retirement vesting provision under which a “qualified” participant who retires under the terms of the provision will receive full accelerated vesting of all shares underlying the award. A “qualified” participant is a participant (1) who is at least age 55 and who was most recently hired on or after January 1, 2025, (2) has completed at least ten full years of service, and (3) who has completed a mandatory transitional period of employment with the company following notice of their planned termination of service. The Career Employment Provision amendments were effective on January 1, 2025, and apply to all grants of equity awards following that date. The applicable provision is based on the employee’s most recent hire date. All NEOs meet the definition of a “legacy qualified” participant with eligibility for the partial vesting acceleration benefit once meeting the age, service and transitional period requirements of the provision. In 2025, the MDCC determined that Mr. Arbuckle was eligible for the retirement vesting provisions of his equity awards. In addition to the benefits that only accrue in connection with a change of control, our agreements with our executive officers provide benefits if we terminate their employment with us without cause or they terminate their employment with us for good reason, as such terms are defined in the applicable agreement with the executive officer. A further discussion of the terms and projected payments under each of our agreements with our NEOs is set forth below under the heading Employment Contracts and Change of Control Arrangements. Tax Considerations Under Section 162(m) of the Internal Revenue Code, publicly held corporations generally may not deduct compensation in excess of $1 million paid to certain executive officers, subject to limited transition relief for certain arrangements in place as of November 2, 2017. We continue to grant performance-based compensation as an important element of our compensation program that aligns corporate shareholder and company interests, even though these awards may not result in full tax deductibility.

    | Compensation Practices |

  143. Additional Factors (accomplishments and/or shortcomings)

    Equity Grant Practices Our MDCC and board of directors generally determine annual equity grants at meetings held each February when individual performance for the year is evaluated. This meeting(s) may occur prior to the company’s release of earnings and filing of its Annual Report on Form 10-K. In such cases, the annual equity awards will be granted on the second full trading day following the company’s release of earnings. This is generally the same date that the company’s trading window opens. For all value-based equity grants, we convert value to shares on the date of grant using the average of the high and low price for the common stock on the day the equity grant is awarded. Newly hired employees, including executive officers, are sometimes granted equity awards effective on the first day of employment. The employees’ start dates are scheduled without regard to anticipated earnings or other major announcements by the company. As a matter of practice, the MDCC and board do not take material non-public information into account when determining the timing and terms of equity awards, and the company has not timed the disclosure of material non-public information for the purpose of affecting the value of executive compensation. We do not currently grant options to our employees, including our executive officers. Compensation Recoupment (“Clawback”) Policies We have adopted a recoupment or clawback policy that is intended to comply with the requirements of the Dodd-Frank Act. Under this policy, in the event we are required to prepare an accounting restatement due to material noncompliance with financial reporting requirements, we are required to recover incentive-based compensation erroneously received by current and former executive officers during the three completed fiscal years immediately preceding the year of the restatement. Erroneous payments will be recovered under the policy even if there was no misconduct or failure of oversight on the part of an individual executive officer. We also have a clawback policy relating to fraud and intentional misconduct. Under that policy, if our board of directors determines that an executive officer engaged in fraud or intentional misconduct that resulted in an incorrect determination that an incentive compensation performance goal had been achieved, the board may take appropriate action to recover from such executive officer any compensation that resulted from such determination. The board may require repayment of any bonus, equity or incentive compensation awarded to an executive officer who engaged in the fraud or intentional misconduct to the extent it was based on such incorrect determination. Stock Ownership Guidelines We have stock ownership guidelines for our NEOs and guidelines for our non-employee directors, as discussed in Non-Employee Director Stock Ownership Guidelines on page 31 of this proxy statement. The guidelines for our NEOs are set forth in the following table:

  144. Additional Factors (accomplishments and/or shortcomings)

    Individual holdings, and holdings of immediate family members, of (a) common stock, (b) unvested RSUs, (c) shares held in a family trust; and (d) shares held through our 401(k) plan count toward meeting these guidelines; unearned PSUs and unexercised stock options do not count toward meeting these guidelines. As of March 16, 2026, each of our NEOs satisfied the individual holding requirements. Anti-Hedging and Pledging Policy Our Insider Trading Policy prohibits all of our directors and employees, including our NEOs, from (a) short selling or hedging our securities, (b) purchasing or selling derivative securities based on our securities, and (c) pledging our securities. Risk Mitigation Our MDCC reviews the risks and rewards associated with our compensation programs. The programs are designed with features that mitigate risk without diminishing the incentive nature of the compensation. We believe our compensation programs encourage and reward prudent business judgment and appropriate risk-taking over the short term and the long term. Our MDCC regularly evaluates the risks involved with our compensation programs and does not believe that any of our compensation programs create risks that are reasonably likely to have a material adverse effect on our company.

  145. Emphasis on Long-term Value Creation and Mitigation of Short-term Risk Taking

    Emphasis on Long-term Value Creation and Mitigation of Short-term Risk Taking Our board believes that a key element of its risk oversight responsibilities is ensuring that our executive compensation program encourages the implementation of our corporate strategy of investing in scientific innovation to create transformative medicines for people with serious diseases and discourages decisions focused on creating short-term financial gains at the expense of long-term value creation. The board reviews our business performance, focusing on financial metrics and non-financial metrics, as well as other strategic factors including talent acquisition and development to ensure our leaders are focusing on long-term growth in a manner aligned with our values. Our MDCC reviews the performance of our executive officers using the above metrics. It also oversees the design of our executive compensation programs to ensure that our executive compensation program does not incentivize our executive officers, either individually or as a group, to make excessively risky business decisions that could maximize short-term results at the expense of long- term value. The independent directors who serve on the MDCC are informed of our most significant risks, including those associated with R&D of new medicines, competition, and the pricing of our medicines. Our MDCC, in consultation with its independent compensation consultant, ensures that our executive compensation programs are aligned with our long-term strategy and do not incentivize overly risky behavior.
