**Dear Shareholders:**

Our strategy is grounded in the conviction that a sustained, disciplined focus on serial innovation – aimed at delivering

transformative medicines for serious diseases with high unmet need – creates enduring value for patients and shareholders.

That conviction was clearly demonstrated in 2025 through strong commercial performance, meaningful pipeline progress,

and robust financial results.

In 2025, we added to our increasingly diversified commercial portfolio by successfully launching JOURNAVX in acute pain,

our fourth commercialized disease area. In cystic fibrosis, we launched ALYFTREK, which builds upon TRIKAFTA by

providing the best CFTR protein function restoration of any of our approved medicines, while also demonstrating efficacy in

additional mutations and allowing for once-daily dosing. In addition, we accelerated adoption of and built significant

momentum for CASGEVY in the U.S., Europe, and the Middle East. Importantly, we also began preparing for the anticipated

near-term commercialization of povetacicept in IgA nephropathy, the first product in our rapidly advancing renal pipeline. We

believe our emerging renal franchise – alongside CF, heme and pain – will be a key driver for Vertex's next period of growth.

On the research and development front, our differentiated strategy has delivered a broad, deep, and advanced pipeline that

has the potential to deliver more transformative medicines. In addition to the ongoing Phase 3 study of povetacicept in IgA

nephropathy, we have four other programs in pivotal development: inaxaplin for APOL1-mediated kidney disease, suzetrigine

for diabetic peripheral neuropathy, zimislecel for type 1 diabetes, and povetacicept for primary membranous nephropathy.

Our earlier stage pipeline is also making strong progress with multiple programs advancing in the proof-of-concept stage:

VX-407 in autosomal dominant polycystic kidney disease, VX-670 in myotonic dystrophy type-1, and povetacicept in

generalized myasthenia gravis.

From a revenue perspective, our total revenues in 2025 were $12 billion, led by cystic fibrosis and with increasing

contributions from CASGEVY and an incremental contribution from the first year of the JOURNAVX launch. Our balance sheet

remains robust and we continue to invest significantly in internal and external innovation to support our differentiated

research and development approach, as well as in the ongoing diversification of our commercialization efforts.

In addition to our business achievements, we remain deeply committed to making a positive impact in the communities

where we live and work. During our annual Week of Service, 83% of Vertex employees around the world contributed more

than 11,800 volunteer hours, impacting the lives of over 64,000 individuals. Vertex and The Vertex Foundation also awarded

approximately $51 million in donations to support initiatives that advance education, health, social innovation, and our

communities. We are also honored that Vertex continued to be recognized as an excellent place to work, receiving

accolades such as Fortune 100 Best Companies to Work For, TIME 100 Most Influential Companies, and U.S. News & World

Report Best Companies to Work For.

It is an exciting time for Vertex. With our leadership in cystic fibrosis, the strength of our products and pipeline, and our

strong financial profile, we are well positioned to deliver on the significant opportunities ahead and to drive sustained growth

over the long term. As Executive Chairman and Chief Executive Officer, we are committed to disciplined execution of our

commercial priorities, driving our serial innovation strategy, and delivering transformative medicines to patients.

Sincerely,

VERTEX PHARMACEUTICALS INCORPORATED - 2026 Proxy Statement<sub>1</sub>

SUMMARY

2025 marked another year of strong revenue growth, commercial diversification, and pipeline advancement. Our strategy of

investing in scientific innovation to create transformative medicines for people with serious diseases, with a focus on specialty

markets, continued to deliver. We have seven approved medicines: five that treat cystic fibrosis ("CF"), one that treats severe sickle

cell disease ("SCD") and transfusion-dependent beta thalassemia ("TDT"), and one that treats moderate-to-severe acute pain. In

2025, we expanded our leadership in CF with the launch of ALYFTREK and ongoing strength in TRIKAFTA, brought CASGEVY to

more patients around the globe, and successfully executed on the first year of our U.S. launch of JOURNAVX, a first-in-class non-

opioid treatment for moderate-to-severe acute pain. We also made important progress with our emerging renal franchise, including

acceleration of the IgA nephropathy ("IgAN") Phase 3 program and preparing for the potential near-term launch of povetacicept in

IgAN. Outside of IgAN, our broad and diverse pipeline continued to make significant progress, with pivotal trials ongoing in APOL1-

mediated kidney disease, diabetic peripheral neuropathy, type 1 diabetes, and primary membranous nephropathy. From a financial

perspective, our strong performance in 2025 resulted in total revenues of $12 billion, representing 9% growth versus 2024, and a

strong balance sheet, ending the year with $12.3 billion in cash and investments.

We are well-positioned to continue to create long-term value for both patients and shareholders, with a marketed product portfolio

of transformative medicines for CF, SCD, TDT, and acute pain; a near-term launch opportunity with povetacicept in IgAN, multiple

mid- and late- stage programs advancing in our pipeline, and a strong balance sheet.

Financial Performance<br>

In 2025, sales of TRIKAFTA/KAFTRIO continued to drive our financial performance along with contributions from ALYFTREK,

JOURNAVX and CASGEVY. We expect continued growth from our CF medicines and increased revenue contributions from

CASGEVY and JOURNAVX in 2026 and beyond.

• Our total revenues increased to $12.0 billion in 2025, an increase of 9% or nearly $1.0 billion, from our 2024 total revenues.

• Our total research and development ("R&D") and selling, general and administrative ("SG&A") expenses increased to $5.7 billion

in 2025 as compared to $5.1 billion in 2024, primarily due to increased investments to commercialize our new products and

advance our R&D pipeline.

• Our acquired in-process research and development expenses ("AIPR&D") included $133.0 million in 2025, primarily due to

various upfront and milestone payments related to our collaboration and in-licensing arrangements, and $4.6 billion in 2024,

including $4.4 billion resulting from our acquisition of Alpine Immune Sciences, Inc. ("Alpine").

PROXY SUMMARY

Marketed Products<br>

In 2025, our commercial focus was to extend our leadership in CF, drive successful launches of ALYFTREK and JOURNAVX, and to

accelerate adoption and commercial momentum for CASGEVY.

• *Cystic Fibrosis*. We continued to build upon our leadership in CF with the launch of our fifth medicine, ALYFTREK, which brings

important benefits for patients in terms of meaningful improvements in CFTR protein function, efficacy in more mutations, and

once-daily dosing, and continued expansion to lower age groups and new geographies.

• *Sickle Cell Diseases and Transfusion-Dependent Beta Thalassemia.* We delivered increased revenue from CASGEVY and drove

more patient initiations, cell collections, and infusions.

• *Acute Pain.* We expanded commercially into our fourth disease area, acute pain, with the U.S. launch of JOURNAVX, a first-in-

class, non-opioid, oral pain signal inhibitor.

Research and Development<br>

We invest in research and development to discover and develop transformative medicines for people with serious diseases, with a

focus on specialty markets. Our research and development strategy is to combine transformative advances in the understanding of

human disease and the science of therapeutics to dramatically advance human health. We aim to serially innovate in our disease

areas and discover, develop, and commercialize first-in-class and/or best-in class therapies. This strategy was designed to deliver

transformative medicines at high rates of speed and success and enable leadership in selected disease areas, and it continues to

deliver. As a result, we currently have five programs in pivotal development: povetacicept for IgAN and primary membranous

nephropathy ("pMN"), inaxaplin for APOL1-mediated kidney disease ("AMKD"), suzetrigine for diabetic peripheral neuropathy, and

zimislecel for type 1 diabetes ("T1D").

Increasing Shareholder Value<br>

Our stock price increased from $405.76 on January 2, 2025, to $452.13 on January 2, 2026. Biotechnology companies are best

measured over the long term as opposed to one-year or other shorter-term increments and we expect that execution of our

differentiated serial innovation strategy will continue to create shareholder value over the long-term. The following chart shows our

total shareholder return relative to the Nasdaq Biotechnology Index and S&P 500 index over the last decade.

PROXY SUMMARY

Corporate Responsibility<br>

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<sup>®</sup> 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.

2025 Compensation Decisions and Pay-for-Performance<br>

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.

**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.

PROXY SUMMARY

Shareholder Outreach and Engagement <br>

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.

Corporate Governance<br>

We are committed to maintaining strong corporate governance practices that promote the long-term interests of our shareholders

and strengthen board and management accountability.

PROPOSAL NO. 1: ELECTION OF DIRECTORS

Our board of directors has nominated the following current directors – Sangeeta Bhatia, Lloyd Carney, Alan Garber, Reshma

Kewalramani, Michel Lagarde, Jeffrey Leiden, Diana McKenzie, Bruce Sachs, Jennifer Schneider, Nancy Thornberry, and Suketu

Upadhyay – for election at our 2026 annual meeting of shareholders to hold office until our 2027 annual meeting of shareholders.

Each of the nominees has agreed to be named in this proxy statement and to serve if elected. We believe that all of the nominees will

be able and willing to serve if elected. However, if any nominee should become unable or unwilling to serve for any reason, proxies may

be voted for another person nominated as a substitute by our board or our board may reduce the number of directors.

Our board of directors is our company's ultimate decision-making body, except with respect to those matters reserved to the

shareholders. Our board selects our senior management team, which in turn is responsible for the day-to-day operations of our

company. Our board acts as an advisor and counselor to senior management and oversees its performance.

Board Structure and Composition

The corporate governance and nominating committee ("CGNC") of our board of directors is responsible for the composition and

structure of our board, including identifying, developing, and recommending qualified candidates for board membership. The CGNC

regularly reviews director competencies, qualities, skills, and experiences with the goal of ensuring that our board consists of directors

who function collegially and effectively and who are able to apply their experience toward meaningful contributions to general corporate

strategy and oversight of corporate performance, risk management, organizational development, and succession planning.

Our by-laws provide that the size of our board may range between three and eleven members. We currently have eleven members on

our board and expect to have eleven members of our board immediately following the 2026 annual meeting of shareholders. Our

CGNC may seek additional director candidates in the future who meet the criteria below to complement the qualifications and

experience of our existing board members. Our CGNC may engage a search firm to recommend candidates who satisfy such criteria.

Director Criteria, Qualifications and Experience<br>

The CGNC seeks to recommend for nomination experienced directors who have substantive knowledge of our business and industry or

who can bring to the board specific and valuable strategic or management capabilities acquired in other industries. The committee

expects each of our directors to have proven leadership, sound judgment, the highest ethics and integrity, and a commitment to our

success. It also seeks personal qualities that foster a respectful environment in which our directors listen to one another and engage in

robust and constructive discussions. These goals for our board composition presuppose a broad range of viewpoints, experiences,

and specific expertise. The CGNC considers a nominee's personal characteristics and business experience relative to those of our

existing board members, including the type of prior management experience, levels of expertise relevant to our business, prior board

service, reputation in the business community, and other factors that the committee believes to be important. When considering

whether to re-nominate a director for board service, the CGNC also considers whether the director has served as a member of our

board for more than 20 years and whether the director is over 72 years of age.

PROPOSAL NO. 1: ELECTION OF DIRECTORS

Board Structure and Composition

Board Refreshment<br>

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<br>

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](#ia256593921614749816b7ebfc4f483d4_166) 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:

---

| | |
|:---|:---|
| **Provision** | **Requirement** |
| Ownership Threshold and <br>Holding Period<br>| 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 <br>board seats (or the closest whole number below 20%) and two.<br>|
| Aggregation Limits | 20-shareholder limit on the number of shareholders who can aggregate their shares to satisfy the <br>3% ownership requirement.<br>|
| Proxy Fights | Proxy access nominees will not be included in the proxy materials if we receive notice that a <br>shareholder intends to nominate a candidate who is not to be included in our proxy materials.<br>|
| Future Ineligibility | Proxy access nominees who fail to receive at least 10% of the votes cast "for" such nominee may <br>not be re-nominated as a proxy access nominee for the next two annual meetings.<br>|

---

The above table is only a summary of our proxy access by-law and is qualified in its entirety by our by-laws.

Majority Votes Cast Standard<br>

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;

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](#ia256593921614749816b7ebfc4f483d4_88) 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.

Audit and Finance Committee<br>

The primary purposes of the audit committee are to:

• assist our board's oversight of our accounting and financial reporting processes, including financial controls and audits of our

financial statements;

• appoint, oversee, and replace, if necessary, our independent registered public accounting firm engaged for the purpose of

preparing or issuing an audit report or performing other audit, review, or attestation services;

• review and discuss our annual audit, quarterly reviews and related disclosures, and oversee our internal audit function;

• review and make recommendations to our board concerning our financial structure, financial strategy, and risks;

• oversee our policies and programs and address risks related to our financial and accounting systems, accounting policies and

investment strategies, internal audit function, and cybersecurity;

• oversee and review material tax matters, including tax structure and strategies;

• address risks arising from related person transactions; and

• assist our board's oversight of our Code of Conduct, related policies and procedures, and ongoing compliance matters as needed.

Our independent registered public accounting firm reports directly to, and is held accountable by, our audit committee in connection

with the audit of our annual financial statements and related services.

Mr. Upadhyay, chair of our audit committee, and Messrs. Lagarde and Carney, members of the audit committee, each qualify as an

"audit committee financial expert" as that term is defined in applicable rules and regulations of the SEC, and each is independent

according to the applicable listing standards of Nasdaq and SEC rules. The report of the audit committee appears on page [35](#ia256593921614749816b7ebfc4f483d4_112) of this

proxy statement.

Board Committees

Our audit committee reviews and approves all transactions with related persons that are required to be disclosed by us pursuant to

Item 404(a) of Regulation S-K promulgated by the SEC, except for transactions, if any, related to the employment of executive officers,

which would be recommended for board approval by the MDCC. Our policies and procedures with respect to transactions with related

persons are governed by our written Related Party Transaction Policy. Pursuant to this policy, related party transactions include

transactions, arrangements or relationships in which our company is a participant, the amount involved exceeds $120,000, and one of

our executive officers, directors, director nominees or 5% shareholders or their immediate family members, whom we refer to as related

persons, has a direct or indirect material interest, except where disclosure of such transaction would not be required pursuant to

Item 404(a) of Regulation S-K. 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. In addition,

she participated in our employee benefit plans on the same basis as other similarly situated employees in 2025.

Corporate Governance and Nominating Committee<br>

The primary purposes of the CGNC are to:

• assist our board in developing and implementing our corporate governance principles;

• recommend the size, composition, and leadership structure of our board and its committees;

• identify and recommend to our board qualified individuals for board membership, accounting for the appropriate balance of

knowledge, experience, skills, expertise, and tenure;

• oversee the CEO succession planning process and assist the board in recruiting and evaluating potential candidates;

• develop and recommend to our board an annual self-evaluation process to assess the effectiveness of our board and its

committees, and coordinate this process;

• oversee risks related to the company's governance structure; and

• review and make recommendations with respect to our committee charters.

Management Development and Compensation Committee<br>

The primary purposes of the MDCC are to:

• assess the overall compensation programs of the company and adopt a written statement of compensation philosophy and

objectives;

• oversee and make recommendations to the board regarding compensation for our CEO;

• oversee and approve compensation for our other executives;

• approve (i) ratings for the company performance against company goals for the prior year and (ii) goals and weighting of goals for

the next year;

• oversee risks associated with our compensation policies, management resources and structure, and management development and

selection processes;

• oversee and make recommendations to the board regarding the compensation of our non-employee directors;

• review and make recommendations to the board regarding new equity plans; and

• oversee and approve the adoption, amendment, administration, and termination of any recoupment policy of the company.

See *[Compensation Discussion and Analysis—Detailed Discussion and Analysis](#ia256593921614749816b7ebfc4f483d4_127)* on page [55](#ia256593921614749816b7ebfc4f483d4_127) for a discussion of the MDCC's role in

Science and Technology Committee<br>

Our S&T committee assists our board in its responsibilities relating to the oversight of our investment in pharmaceutical R&D. In

furtherance of that oversight function, the S&T committee:

• reviews and assesses our current and planned R&D programs and technology initiatives from a scientific perspective;

• assesses the depth and breadth of our scientific personnel and resources; and

• provides strategic advice to our board regarding emerging science and technology issues and trends.

Compensation Committee Interlocks and Insider Participation<br>

Messrs. Sachs, and Upadhyay, Ms. McKenzie, and Dr. Schneider served on the MDCC during 2025. Each member of the MDCC was

an independent director while serving on the MDCC. None of the members of the MDCC has been an officer or employee of the

company. None of the members of our MDCC had a relationship with the company or any of its subsidiaries during 2025 that would be

required to be disclosed pursuant to Item 404(a) of Regulation S-K. During 2025, none of our executive officers served as a member of

the board of directors or compensation committee of another company that has one or more executive officers serving as a member of

our board or MDCC.

Board Attendance, Committee Meetings, and Committee Membership

During 2025, our board of directors met seven times. Each of our directors attended at least 90% of the total meetings of the board and

the board committees on which the director served that were held during the time that person was a director in 2025. All of our

directors attended our 2025 annual meeting of shareholders.

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.

PROPOSAL NO. 2: RATIFICATION OF THE

APPOINTMENT OF

INDEPENDENT

REGISTERED PUBLIC

ACCOUNTING FIRM

Engagement of Ernst & Young LLP

Our audit committee is responsible for the appointment, compensation, and oversight of our independent registered public accounting

firm. Ernst & Young LLP has been our independent registered public accounting firm since 2005, and we believe that the selection of

Ernst & Young LLP as our independent registered accounting firm for the year ending December 31, 2026 is in the best interest of our

company and our shareholders.

In determining whether to reappoint our independent registered public accounting firm, our audit committee undertakes an annual

formal evaluation of the independent registered public accounting firm. That evaluation considers the quality of its discussions with, and

the performance of, the lead audit partner, the audit team assigned to our account, the potential impact of changing our independent

registered public accounting firm, the overall strength and reputation of the firm and issues pertaining to auditor independence,

including fees that our independent registered public accounting firm receives for non-audit services. In accordance with applicable

requirements, we are required to change our lead audit partner every five years.

Representatives of Ernst & Young LLP are expected to attend the annual meeting, will have the opportunity to make a statement if they

desire to do so, and will be available to respond to appropriate questions from shareholders.

Effect of Vote

Although we are not required to have shareholders ratify the selection of Ernst & Young LLP, our board is submitting this proposal to

our shareholders for ratification as a matter of good corporate practice. If our shareholders do not ratify the selection, our audit

committee will reconsider the selection of Ernst & Young LLP for the ensuing year, but may determine that continued retention of

Ernst & Young LLP is in our company's and our shareholders' best interests. Even if the appointment is ratified, the audit committee, in

its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if it

determines that such a change would be in our company's and our shareholders' best interests.

Independent Registered Public Accounting Firm Fees

The audit committee works with our management to negotiate appropriate fees with Ernst & Young LLP and is ultimately responsible

for approving those fees. The following is a summary and description of fees for services provided by Ernst & Young LLP in 2025

and 2024.

***"Audit-related fees"*** refer to fees for accounting consultations.

***"Tax fees"*** consisted of fees related to tax compliance, worldwide tax planning, and tax advice. The tax fees for 2025 and 2024

consisted of:

• tax compliance and preparation fees, including the preparation of original and amended tax returns and refund claims, and tax

payment planning of $930,000 and $976,000, respectively; and

• tax advice and planning fees of $475,000 and $350,000, respectively.

***"All other fees"*** consisted of completion of a SOC2 audit engagement and licensing fees paid to access Ernst & Young LLP's

proprietary accounting research database.

Audit and Finance Committee Pre-Approval Policies and Procedures

Our audit committee has established a policy to pre-approve all audit and permissible non-audit services provided by our independent

registered public accounting firm. Prior to the engagement of the firm for each year's audit, management submits to our audit

committee for approval a description of services expected to be rendered during that year for each of the following four categories of

services and a budget for those services in the aggregate.

• **Audit fees** include fees for audit work performed in the preparation of financial statements, as well as work that generally only our

independent registered public accounting firm can reasonably be expected to provide, including comfort letters, statutory audits,

consents, and attestation services.

• **Audit-related fees** relate to services for assurance and related services that traditionally are performed by the independent

registered public accounting firm, including due diligence related to mergers and acquisitions, employee benefit plan audits, special

procedures required to meet certain regulatory requirements, and consultation regarding financial accounting and/or reporting

standards.

• **Tax fees** include fees for all services performed by the independent registered public accounting firm's tax personnel except those

services specifically related to the audit of our financial statements, and include fees in the areas of tax compliance, tax planning,

and tax advice.

• **All other fees** are those associated with services not captured in the three preceding categories.

Prior to the engagement of our independent registered public accounting firm, our audit committee pre-approves these services by

category of service. The fees are budgeted and our audit committee requires the independent registered public accounting firm and

management to report actual fees versus the budget periodically throughout the year by category of service. During the year,

circumstances may arise when it may become necessary to engage the independent registered public accounting firm for additional

services not contemplated in the original pre-approval. In those instances, our audit committee requires that we obtain its specific

pre-approval for these services.

The audit committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is

delegated must report any pre-approval decisions to our audit committee at its next scheduled meeting.

All of the services set forth above in the categories "audit-related fees," "tax fees," and "all other fees" were pre-approved and none

were approved by our audit committee pursuant to Rule 2-01(c)(7)(i)(C) of Regulation S-X, which relates to the approval of a de minimis

amount of non-audit services after the fact but before completion of the audit.

The affirmative vote of a majority of the shares represented and entitled to vote on this matter is required for the approval of this

proposal.

**Our board of directors unanimously recommends that you vote <u>FOR</u> ratification of the appointment** <br>**of Ernst & Young LLP as our independent registered public accounting firm for the year ending** <br>**December 31, 2026.**<br>

AUDIT AND FINANCE COMMITTEE REPORT

The Audit and Finance Committee of the Board of Directors (the "Audit Committee") oversees the company's accounting, auditing and

financial reporting process, financial risk assessment and management process, and monitors compliance with certain regulatory and

compliance matters, on behalf of the Board of Directors. Management of the company is responsible for preparing the financial

statements, for establishing and maintaining adequate internal financial and disclosure controls, and for the public reporting process.

Ernst & Young LLP ("Ernst & Young"), the company's independent registered public accounting firm, is responsible for expressing an

opinion on the conformity of the company's audited financial statements with generally accepted accounting principles and on the

company's internal control over financial reporting.

The Audit Committee reviewed and discussed the company's audited financial statements for the year ended December 31, 2025 with

Ernst & Young and the company's management, as well as Ernst & Young's audit of the company's internal control over financial

reporting. In addition, the Audit Committee has discussed with Ernst & Young the matters that are required to be discussed by the

applicable requirements of the Public Company Accounting Oversight Board (the "PCAOB") and the U.S. Securities and Exchange

Commission ("SEC"). These communications and discussions are intended to assist the Audit Committee in overseeing the financial

reporting and disclosure process.

The Audit Committee also has received from Ernst & Young the written disclosures and the letter concerning independence as required

by the applicable requirements of the PCAOB regarding Ernst & Young's communications with the Audit Committee regarding

independence and has discussed with Ernst & Young the firm's independence. The Audit Committee has also concluded that Ernst &

Young's provision of audit and non-audit services to the company is compatible with Ernst & Young's independence from the Audit

Committee and the company's management.

Based on the review and discussions noted above, the Audit Committee recommended to the company's Board of Directors that the

audited financial statements for the year ended December 31, 2025 be included in the company's Annual Report on Form 10-K for filing

with the SEC. This report is provided by the following independent directors, who comprise the Audit Committee:

**Suketu Upadhyay *(Chair)***

**Lloyd Carney**

**Michel Lagarde**

**Diana McKenzie**

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.

PROPOSAL NO. 3: ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

Our executive compensation program, including our performance and the compensation of our NEOs, is discussed in greater detail in

the *Compensation Discussion and Analysis* section beginning on page [49](#ia256593921614749816b7ebfc4f483d4_121) of this proxy statement.

As required by Section 14(a) of the Exchange Act, our board of directors is asking that shareholders cast a non-binding, advisory vote

FOR the following resolution:

*RESOLVED, that the compensation of our named executive officers, as disclosed pursuant to the rules of the Securities and* 

*Exchange Commission, including the Compensation Discussion and Analysis, the Compensation and Equity Tables and the* 

*related narrative executive compensation disclosures contained in this proxy statement, is hereby APPROVED.*

The vote on this resolution is advisory and not binding on the board. However, our MDCC and board intend to consider carefully the

outcome of the shareholder vote when considering future executive compensation program matters.

**Our board of directors unanimously recommends that you vote <u>FOR</u> the approval of the resolution set** <br>**forth above.**<br>

PROPOSAL NO. 4: APPROVAL OF 2026 STOCK

## AND OPTION PLAN
We are requesting that our shareholders approve our 2026 Stock and Option Plan (the "2026 Plan"), which will replace our Amended and

Restated 2013 Stock and Option Plan (the "2013 Plan"). We believe that a comprehensive equity compensation program serves as a

necessary and powerful tool to attract, retain and motivate people essential to our success. Accordingly, such an equity compensation

program benefits all of our shareholders by allowing us to retain individuals who are expected to make significant contributions to the

creation of shareholder value. If the 2026 Plan is approved by our shareholders, it will become effective on May 13, 2026 and no further

awards will be granted under the 2013 Plan.

Maintenance of Broad-Based Equity Program While Managing Dilution

Since our inception, we have compensated all eligible employees using a mix of cash and equity. The broad-based nature of our equity

compensation program is an important element of our overall employee compensation program and reflects our philosophy that it is

important for all of our employees to approach their jobs with a long-term commitment and perspective. Our board approved the 2026

Plan in part because additional shares will be required to continue to grant equity broadly across our employee population. Failure to

do so would place us at a competitive disadvantage with the other biotechnology companies against whom we compete for talent.

In establishing the size of the share pool under the 2026 Plan, the board considered the number of equity awards we granted over the

period from 2022 through 2025, which declined on an absolute basis over such period, and the reduction in our "gross burn rate" from

0.9% in 2022 to 0.8% in 2025.

(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.

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

---

---

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.

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.

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.

PROPOSAL NO. 5: SHAREHOLDER

PROPOSAL REGARDING

SHAREHOLDER

RIGHT TO ACT BY

WRITTEN CONSENT

We expect the following shareholder proposal will be presented for consideration at the 2026 annual meeting of shareholders. The

shareholder proposal will be voted on at the 2026 annual meeting of shareholders only if properly presented by or on behalf of the

proponent. Our board of directors unanimously recommends a vote AGAINST this shareholder proposal for the reasons set forth

following the proposal.

Vertex is not responsible for the content of this shareholder proposal or supporting statement.

The Shareholder Proposal

John Chevedden, 2215 Nelson Avenue, No. 205, Redondo Beach, California 90278, an owner of at least $2,000 worth of shares of our

common stock as of December 3, 2025, has given notice that he intends to present the following proposal for action at our 2026 annual

meeting of shareholders.

Supporting Statement

**Proposal 5 — Shareholder Right to Act by Written Consent**

![435534-1_Chevedden Graphic.jpg](vrtx-20260402_g50.jpg)

Shareholders request that the board of directors take the necessary steps to permit written consent by the shareholders entitled to cast

the minimum number of votes that would be necessary to authorize an action at a meeting at which all shareholders entitled to vote

thereon were present and voting (without any unnecessary restriction based on length of stock ownership or the method by which

shareholders hold their shares). This includes shareholder ability to initiate any appropriate topic for written consent.

Vertex Pharmaceuticals (VRTX) shareholders have a particular need for the right to act by written consent because it is considerably

more difficult than necessary for VRTX shareholders to call for a special shareholder meeting.

Shareholders acting by written consent and calling for a special shareholder meeting are 2 means that shareholders of a company can

use to put forth a proposal on a timely basis without waiting for the annual shareholder meeting.

Delaware law considers it reasonable for 10% of shareholders to call for a special shareholder meeting - yet VRTX made the threshold

25% of shareholders based on all shares outstanding.

Acting by written consent is hardly ever used by shareholders but the main point of having a right to act by written consent is that it

gives shareholders greater standing to engage effectively with management when VRSK underperforms.

The following challenging 2025 news reports on VRTX make it more important to adopt this proposal without delay:

In August 2025, VRTX announced that VX-993, an investigative non-opioid acute pain treatment, did not meet its primary endpoint in a

Phase 2 trial. As a result, VRTX decided not to advance it as a monotherapy, leading to a significant drop in the stock price.

The U.S. Food and Drug Administration (FDA) indicated it currently did not see a path to a broad label for suzetrigine for peripheral

neuropathic pain (PNP), which could limit the drug's immediate market potential in that indication.

In March 2025, VRTX discontinued the development of VX-264, a cell device program for type 1 diabetes, after it failed to meet the

efficacy endpoint in a Phase 1/2 study.

PROPOSAL NO. 5: SHAREHOLDER PROPOSAL REGARDING SHAREHOLDER RIGHT TO ACT BY WRITTEN CONSENT

VRTX temporarily paused the multiple ascending dose (MAD) portion of a Phase 1/2 clinical study for VX-522, an mRNA therapeutic

being developed with Moderna for cystic fibrosis patients who cannot use other modulators.

VRTX stock experienced major drops in May and August 2025 following these clinical trial results and an initial first-quarter earnings

miss, with the market reacting negatively to the pipeline setbacks.

VRTX temporarily postponed the completion of dosing in a Phase 1/2/3 study for its Type 1 diabetes treatment, zimislecel, pending an

internal manufacturing analysis.

Please vote yes:

PROPOSAL NO. 5: SHAREHOLDER PROPOSAL REGARDING SHAREHOLDER RIGHT TO ACT BY WRITTEN CONSENT

Board of Directors' Statement in Opposition

The board has carefully considered the proposal concerning a shareholder right to act by written consent and recommends a vote

**AGAINST** Proposal 5 because:

• Shareholder meetings offer important protections and advantages that are absent from the written consent process.

• A written consent process is unnecessary given the ability of shareholders holding 25% or more of our outstanding shares to call

special meetings of shareholders and, further, a written consent process does not promote transparent decision-making and could

disenfranchise shareholders.

• Our robust shareholder engagement program provides shareholders with multiple opportunities to provide input to management and

our board.

• We already have strong corporate governance practices in place that protect shareholder rights and ensure board accountability

and responsiveness to shareholders.

Shareholder meetings provide a more transparent, informed, and fair process for all shareholders to

exercise their rights

Actions taken through a meeting, whether at an annual or special meeting of shareholders, better serve shareholders' interests

because all shareholders are provided with an opportunity to participate in an open, transparent, and fair decision-making process. We

conduct an annual shareholder meeting during which shareholders elect directors and may also raise other items for shareholder

consideration, and, as described in more detail below, shareholders are also permitted to call special meetings. Some of the

protections and advantages of shareholder meetings, which are absent from the written consent process, are as follows:

• All communications with respect to proposed actions to be taken at a shareholder meeting are governed by SEC rules that require

fair disclosure to all shareholders, preventing a select group of shareholders (including special-interest investors) from approving

critical actions without advance notice to, or participation by, other shareholders or the company;

• A shareholder meeting and the resulting shareholder vote take place in a transparent manner on a specified date that is publicly

announced well in advance;

• Accurate and complete information about the proposed action is included in a proxy statement, which is broadly distributed to all

shareholders before the meeting;

• Shareholders can engage meaningfully in the process, voice any concerns, offer perspectives, and cast or change their vote; and

• The board is able to analyze and provide a recommendation to shareholders on all actions proposed to be taken.

The current right of holders of 25% of our shares to request a special meeting of shareholders is

preferable to a written consent right because a written consent process does not promote transparent

decision-making and could disenfranchise shareholders

Our shareholders have the right to call special meetings, which ensures that all shareholders have a voice in critical matters affecting

the Company and their interests. After careful consideration of the views expressed during our extensive shareholder outreach, in

February 2025, our board amended our by-laws to reduce the special meeting threshold from 40% to 25%. Consistent with the

feedback we received from many of the shareholders with whom we engaged, our board believes that our current special meeting right

strikes an appropriate balance between ensuring that shareholders have a meaningful right to call a shareholder meeting and

protecting against the risk that a small minority of shareholders could trigger a special meeting that is not in the best interest of all

shareholders.

Our board believes that all shareholders should have the opportunity to consider and vote on matters that require shareholder

approval. By contrast, a written consent process would make it possible for a small group of shareholders to initiate significant

corporate action without understanding the board's perspective and without any prior notice or disclosure to other shareholders or the

company. As a result, the board may not have a meaningful opportunity to consider the merits of the proposed action, to consider

alternative courses of action or to communicate its views to shareholders. Similarly, other shareholders could also be deprived of the

opportunity to deliberate in an open and transparent manner and to consider arguments for and against any action. This would

effectively disenfranchise those shareholders, decreasing transparency and increasing the risk of potential abuse.

PROPOSAL NO. 5: SHAREHOLDER PROPOSAL REGARDING SHAREHOLDER RIGHT TO ACT BY WRITTEN CONSENT

Our robust shareholder engagement program provides shareholders with multiple opportunities to provide

input to company management and our Board

Our established shareholder communication and engagement practices provide shareholders with meaningful opportunities to raise

important matters. In 2025, management solicited feedback regarding our corporate governance practices from shareholders holding

approximately 70% of our outstanding shares and is committed to ongoing shareholder engagement. This feedback is shared with our

board, which considers these perspectives as part of its evaluation and review of our practices and disclosures. The company

maintains open lines of communication to regularly engage with our investors to learn and understand their views.

Vertex already has strong corporate governance practices in place that protect shareholder rights and

promote Board accountability and responsiveness to shareholders

Our board is committed to adopting and following best practices in corporate governance to promote board accountability and

responsiveness to shareholders. The board believes that this proposal should be viewed in the context of our overall strong corporate

governance practices, which, in addition to our existing 25% special meeting right, include:

• **Annual Election of Directors.** At each annual meeting of shareholders, each director nominee is elected to hold office for a one-

year term expiring at the next annual meeting of shareholders.

• **Majority Vote Standard.** Our by-laws provide for the election of directors by a majority of votes cast standard in uncontested

elections.

• **Board Independence.** All of our directors are independent, with the exception of our CEO and Executive Chairman. We have a

strong Lead Independent Director with robust duties, and our board committees are comprised solely of independent directors.

• **Board Refreshment.** The board maintains a thoughtful and active refreshment process to identify independent directors with skill

sets that enhance the composition of our board, support the company's growth and strategy, and enable effective oversight. Six of

our eleven directors have joined our board since 2020, including five new independent directors.

• **Proxy Access.** Our by-laws provide shareholders with proxy access rights to nominate directors for election to be included in our

proxy statement.

**•No Supermajority Voting Provisions.** Our articles of organization and by-law provisions do not have supermajority voting

provisions - shareholders can approve binding articles of organization and by-law amendments with a majority vote.

• **Annual "Say on Pay" Advisory Vote.** We hold an annual advisory vote on executive compensation to allow shareholders the

opportunity to express their views on executive compensation matters.

Based on the foregoing, our board believes that the written consent procedures, with its potential for abuse and disenfranchisement of

shareholders, would not provide any additional benefit to our shareholders.

**For all of the above reasons, our board of directors unanimously recommends that you vote <u>AGAINST</u>** <br>**this shareholder proposal.**<br>

COMPENSATION DISCUSSION AND ANALYSIS

Letter from Management Development and Compensation Committee

to Our Shareholders

**Dear Fellow Shareholders,**

The Management Development and Compensation Committee oversees Vertex's compensation programs with a focus on

advancing the company's mission of developing transformative medicines for people with serious diseases while driving long-term

shareholder value. We approach our responsibilities seriously, recognizing the critical role compensation plays in attracting,

motivating, and retaining exceptional executive talent. Vertex's continued performance and effective execution of its business

strategy in recent years have been driven in large part by the leadership, continuity, and operational strength of our senior

executive team.

We have designed the company's compensation programs to closely align management's incentives with Vertex's strategic long-

and short-term goals and with the interests of Vertex's shareholders. We believe this alignment has driven more than a decade of

significant achievements, including Vertex's enduring market leadership in CF, historic global approvals of CASGEVY, the first

CRISPR-base gene therapy to be approved in the world, and the launch of JOURNAVX, a first-in-class, non-opioid treatment for

acute pain, in the U.S. All the while, Vertex has maintained a strong financial position with significant growth in revenues, continued

delivery of strong operating margins and cash flows, and accelerated the advancement of its clinical-stage pipeline across

multiple disease areas and modalities.

In 2025, Vertex reached more CF patients than ever, including patients with new mutations, younger patients, and patients in new

geographies, and continued its march toward commercial diversification by building momentum for CASGEVY and successfully

launching JOURNAVX. Additionally, Vertex set the stage to establish nephrology leadership with the potential near-term

commercial launch of povetacicept as a treatment for IgAN.

It was also a significant year for Vertex as the company continued to successfully execute its research and development strategy.

The research and development team made meaningful progress advancing several programs across multiple modalities and now

has a total of five disease areas in pivotal development, including IgAN, APOL1-mediated kidney disease, diabetic peripheral

neuropathy, type 1 diabetes, and primary membranous nephropathy. Furthermore, the company is progressing several early and

mid-stage programs, including in autosomal dominant polycystic kidney disease, myotonic dystrophy type 1, and generalized

myasthenia gravis, while also continuing to execute on its serial innovation strategy across all disease areas of interest. With these

advancements, Vertex's research and development strategy is continuing to deliver a broad and deep pipeline of potentially

transformative therapies, thereby providing the opportunity for creating additional meaningful value for patients and shareholders.

These accomplishments have been recognized by the company's shareholders and have been reflected in the increasing value

attributed to the company. Over the last decade, Vertex has secured approval for and launched six transformative medicines and

increased its market capitalization from approximately $31 billion at the end of 2015 to approximately $115 billion at the end of

2025. The company delivered strong financial performance in 2025, achieving total revenues of $12 billion, a 9% increase compared to

2024. The company finished the year with $12.3 billion in total cash and investments. The senior management team additionally

strengthened the company's organizational capabilities by executing on key initiatives to support growth and scale, recruiting and

retaining top-tier talent, and advancing capital projects.

The company's strong performance in 2025 reflects the effective execution of its differentiated corporate strategy under the

leadership of the senior management team. In recognition of these results, executive compensation outcomes from 2025 included

above-target cash incentives and performance stock unit payouts tied to the achievement of both annual financial objectives and

longer-term, three-year strategic milestones. We believe these outcomes demonstrate our commitment to a pay-for-performance

philosophy. Looking ahead, we will continue to emphasize a close alignment between Vertex's compensation programs and the

execution of its corporate strategy, with a focus on attracting and retaining a highly capable, aligned executive team and driving

long-term shareholder value.

**Sincerely, Bruce I. Sachs *(Chair)***

• Our total revenues increased to $12.0 billion in 2025, an increase of 9% or nearly $1.0 billion, from our 2024 total revenues.

• Our total R&D and SG&A expenses increased to $5.7 billion in 2025 as compared to $5.1 billion in 2024, primarily due to increased

investments to commercialize our new products and advance our R&D pipeline.

• Our AIPR&D expenses included $133.0 million in 2025, primarily due to various upfront and milestone payments related to our

collaboration and in-licensing arrangements, and $4.6 billion in 2024, including $4.4 billion resulting from our acquisition of Alpine.

COMPENSATION DISCUSSION AND ANALYSIS

Executive Summary

Marketed Products<br>

In 2025, our commercial focus was to extend our leadership in CF, drive successful launches of ALYFTREK and JOURNAVX, and

accelerate patient adoption and commercial momentum for CASGEVY.

**Cystic Fibrosis** 

For more than 20 years, our goal has been to address the underlying cause of CF and to bring more people with the disease to normal

levels of CFTR function. We have continued to serially innovate in the years since the 2012 approval of KALYDECO, which was first

approved to treat a CF population of approximately 1,000 people in the U.S. We now have five medicines that treat CF, and we believe

nearly 95% of the estimated 112,000 people with CF in all target markets could benefit from these medicines. In 2025, we continued to

reach more people with CF through continuing the launch of ALYFTREK and through securing approvals for our medicines for younger

patients and additional mutations, and securing increased access to and reimbursement for our CF medicines around the world.

**Sickle Cell Disease and Transfusion-Dependent Beta Thalassemia** 

2025 was a year of accelerating momentum for CASGEVY, our ex-vivo, non-viral CRISPR/Cas9-based gene-editing therapy for severe

SCD and TDT. CASGEVY is approved in the U.S and across multiple geographies including Europe, Canada, and the Middle East, and

is broadly reimbursed by third-party payors in the U.S. Outside of the U.S., patients have access to CASGEVY in Austria, Denmark, the

U.K., Italy, Luxembourg, Bahrain, Saudi Arabia, the United Arab Emirates, and Kuwait. Many hundreds of patients have initiated the

treatment journey for CASGEVY, a groundbreaking therapy that is transforming the lives of people with severe SCD and TDT around the

globe.

**Acute Pain** 

In January 2025, the FDA approved JOURNAVX for the treatment of moderate-to-severe acute pain in adults. JOURNAVX is a first-in-

class, oral pain signal inhibitor that is highly selective for NaV1.8 voltage-gated sodium channels. Through this mechanism, JOURNAVX

provides effective relief of pain without evidence of the limitations of other currently available therapies, including the addictive potential

of opioids. Since launch, we have obtained broad access for JOURNAVX and, by the end of 2025, more than 550,000 prescriptions

were written and filled. We expect to leverage momentum from our first year of launch to drive continued prescription and revenue

growth for JOURNAVX in 2026.

Research and Development<br>

We invest in research and development to discover and develop transformative medicines for people with serious diseases, with a

focus on specialty markets. Our research and development strategy is to combine transformative advances in the understanding of

human disease and the science of therapeutics to dramatically advance human health. We aim to serially innovate in our disease areas

and discover, develop, and commercialize first-in-class and/or best-in class therapies. This strategy was designed to deliver

transformative medicines at high rates of speed and success and enable leadership in selected disease areas, and it continues to

deliver. We have a broad and deep research and development program with five programs in pivotal development:

*•IgA Nephropathy*. We are developing povetacicept, a potent dual inhibitor of the B cell activating factor ("BAFF") and a proliferation-

inducing ligand ("APRIL") cytokines, as a potentially best-in-class approach to treat IgAN, a serious, progressive, life-threatening

kidney disease that often progresses to end-stage renal disease. In March, we announced positive data from the interim analysis of

the IgAN Phase 3 clinical trial evaluating povetacicept.

*•APOL1-Mediated Kidney Disease.* We are developing inaxaplin, a small molecule inhibitor of APOL1 as a potential first-in-class

treatment for AMKD. We have completed the enrollment of the interim analysis cohort of the Phase 2/3 clinical trial and will conduct

the pre-planned interim analysis once this cohort reaches 48 weeks of treatment. We expect to share data from the interim analysis

in late 2026 or early 2027.

*•Peripheral Neuropathic Pain.* We are developing suzetrigine, a selective non-opioid NaV1.8 pain signal inhibitor, for diabetic

peripheral neuropathy, a common form of peripheral neuropathic pain. We are evaluating suzetrigine for the treatment of diabetic

peripheral neuropathy in two Phase 3 clinical trials. We expect to complete enrollment in both Phase 3 clinical trials by the end of

2026. *•Type 1 Diabetes.* Zimislecel is an allogeneic, stem-cell derived, fully differentiated islet cell therapy in pivotal development for the

treatment of T1D. We have completed enrollment in the Phase 1/2/3 clinical trial of zimislecel in people with T1D. We have

temporarily postponed completion of the dosing in this clinical trial, pending an ongoing internal manufacturing analysis.

• *Primary Membranous Nephropathy*. We are also developing povetacicept to treat pMN, a rare and serious autoimmune glomerular

disease that can lead to kidney damage and renal failure. We continue to enroll and dose patients in the adaptive Phase 2/3 pivotal

trial in people with pMN. We expect to complete the Phase 2 portion of the clinical trial and to initiate the Phase 3 portion in

mid-2026.

measured over the long term as opposed to one-year or other shorter-term increments and we expect that execution of our

differentiated serial innovation strategy will continue to create shareholder value over the long-term. The following chart shows our total

shareholder return relative to the Nasdaq Biotechnology Index and S&P 500 index over the last decade.

![Stock Price Chart 2.18-crop.jpg](vrtx-20260402_g26.jpg)<br>

2025 Compensation Decisions and Pay-for-Performance<br>

In 2025, our executive compensation program received substantial support from our shareholders, with approval by approximately 92%

of the votes cast at the annual meeting of shareholders. We believe this support is consistent with our long-term shareholders'

understanding of our business model, our pay-for-performance compensation philosophy and the long-term value we are creating. Our

executive compensation program is intended to align executive compensation with the company's short- and long-term performance

and to provide the compensation and incentives required to attract, motivate and retain our high-caliber executives who are crucial to

Vertex's long-term success. **Our compensation program is highly performance-based, with 90% of our NEO compensation tied to** 

**performance.** Retention of our talented executives is critical, as their outstanding performance has led to the company's advancement

and the creation of significant long-term shareholder value.

In 2025, our board of directors and MDCC reviewed our compensation programs and made the following key decisions:

• **Program Design:** We maintained our compensation program design that directly ties pay with performance and that we believe has

contributed to our short- and long-term successes.

• **Base Salary:** In connection with his appointment as Chief Operating and Financial Officer, Mr. Wagner's base salary was increased

to $1 million from $950,000. Based on a comparative analysis of companies in our Peer Group (described below), we maintained the

base salaries for all of our other NEOs.

• **Annual Cash Bonus:** In connection with his appointment as Chief Operating and Financial Officer, Mr. Wagner's target cash bonus

was increased to 100% of his base salary from 90% of his base salary. We maintained the target cash bonus, which is a percentage

of base salary, for all of our other NEOs based on a comparative analysis of companies in our Peer Group (described below). The

company's performance in 2025, as described above, resulted in the board determining that the company achieved a Leading

rating for 2025 (a rating of 131 out of a total potential score of 150) and the payment of above-target annual cash bonuses. Please

see *[Overview of Company Performance Rating & Achievement in 2025](#i1b549f248e974347b59d0410e55fc6cb_38389)* on page [60](#i1b549f248e974347b59d0410e55fc6cb_38389).

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](#ifb155efa87e04ddd8cd24009185e1446_0-0-1-1-344315) 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.

Shareholder Outreach and Engagement<br>

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 Governance Practices<br>

We continue to implement and maintain leading practices in our compensation program, shareholder outreach and related areas.

COMPENSATION DISCUSSION AND ANALYSIS

Detailed Discussion and Analysis

Detailed Discussion and Analysis

Compensation Philosophy<br>

Our MDCC regularly reviews the elements of the individual compensation packages for our executive officers to ensure that they

continue to support the achievement of the following primary objectives:

• attract, retain, and motivate talented, experienced, and high-performing individuals across all areas of our business;

• align the interests of our executive officers with the interests of our shareholders as we seek to create value through the discovery,

development, and commercialization of transformative medicines; and

• ensure that the vast majority of compensation is tied to company and individual performance.

Our executive officers have had long and varied careers and possess a wide range of backgrounds and skills that make them

extremely valuable members of our executive team and our company as a whole. The leadership, stability and commitment of this team

have been instrumental in building Vertex into the company it is today: one with a leadership position and continued innovation in CF, a

landmark gene-edited cell therapy for SCD and TDT, the first in a new class of acute pain medicine approved in more than 20 years, a

broad, deep, and advancing pipeline, increasing revenues, and a strong financial profile. All of these factors position Vertex to achieve

its strategic objectives in future years.

Our MDCC seeks to directly link the achievement of our strategic objectives with our compensation program in a number of ways,

including through detailed and measurable company goals that underlie our annual cash bonuses and the performance-based

components of our equity awards. Our company goals address several key objectives, including increasing revenues from our current

products, achieving commercial manufacturing and R&D objectives, enhancing organizational capabilities, and maintaining financial

strength. We believe this mix provides an appropriate balance between near- and long-term objectives and financial and organizational

development objectives. These objectives are selected specifically because they are considered by our MDCC to be measurable

milestones that our company must achieve if it is to maintain its significant revenue growth, superior profitability, and ability to continue

creating value over the long-term. Our MDCC expects to continue seeking balance in the use of financial metrics, R&D,

commercialization and manufacturing goals to motivate our executive team to achieve financial and strategic objectives, while

providing appropriate incentives for our management to continue to make investments in our business for the long term.

In determining compensation, we consider compensation paid by similar companies as a reference point among other factors, such as

the performance, competencies, experience and specific role responsibilities of our NEOs, and do not benchmark compensation at any

particular level. Our MDCC retains flexibility to structure compensation based on good governance practices, our objectives of building

our company and creating value for our shareholders, and, most importantly, discovering, developing, and delivering transformative

medicines for patients who can benefit from them.

Compensation Decision-Making Process <br>

Role of MDCC, Executive Chairman, and CEO in Setting Executive Compensation

The MDCC has responsibility for overseeing the design, development, and implementation of the compensation program for our CEO,

other executive officers, and senior leaders. The MDCC evaluates the performance of our CEO and other executive officers. Our CEO,

our Executive Chairman, and our human resources group assist the MDCC in evaluating the performance of our other executive

officers, including the NEOs other than the CEO. The members of the MDCC, each of whom is an independent director, make final

compensation decisions for the executive officers other than the CEO.

Our CEO does not make any recommendations to the MDCC regarding CEO compensation and does not participate in the portions of

MDCC meetings or meetings of the board of directors when CEO compensation is discussed or determined.

The MDCC makes a recommendation regarding CEO compensation to the independent directors of the board, who make final

compensation decisions for the CEO.

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:

---

| | |
|:---|:---|
| **Factor Considered** | **What We Look For** |
| Similar industry | Biotechnology or pharmaceutical industry |
| Importance of medicines to patients and society  | Transformative medicines for serious diseases; therapeutics for <br>unmet needs<br>|
| Recognized focus on innovation | Breakthrough Therapy designations, priority review and/or other <br>markers indicating unmet need<br>|
| Global operations | Significant operations both within and outside the U.S. |
| Commercial operations | Marketing and selling approved medicines |
| Significant R&D investment | Greater than $2.2B or 25% of revenue |
| Number of employees | Greater than 2,000 employees |
| Market capitalization and significance to broader economy | Market cap at least ¼ our size and/or inclusion in S&P 500 or <br>Nasdaq 100<br>|
| Labor market competitor | Companies we compete with for executive talent |
| Companies that use Vertex as a peer  | Inclusion of Vertex in proxy reported peer group |

---

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.

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:

*\*Jazz Pharmaceuticals plc is a Peer Group company*

Elements of Annual Compensation<br>

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**.

COMPENSATION DISCUSSION AND ANALYSIS

Detailed Discussion and Analysis

**Performance-Based Value-Based Program**

We have a performance-based program that is consistent with programs implemented by our peers and allows us to attract, retain, and

motivate talented and highly experienced individuals across all areas of our business. We focus on the following performance-

based elements:

---

| | |
|:---|:---|
| **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 <br>differentiation for individual performance<br>•Value of shares granted based on target set by the MDCC, adjusted for individual <br>performance ranging from 0% for below target individual performance, 100% at target <br>individual performance, and up to 150% for above target individual performance <br>|
| **PSU Awards** | •50% of PSUs with a range of shares earned from 0% to 200% of target based on one-year <br>financial metrics (to the extent earned, vesting in equal installments over a three-year period)<br>•50% of PSUs with a range of shares earned from 0% to 200% of target based on three-year <br>non-financial metrics (to the extent earned, cliff-vesting after three years) <br>|
| **Time-Based RSUs** | •Value of awards increases or decreases based on stock price over the three-year vesting <br>period<br>•We consider our time-vesting RSU awards to be performance-based awards because the <br>target number of RSUs awarded may be adjusted based on the corresponding executive's <br>individual performance for the relevant performance period prior to grant as well as the <br>resulting value dependent upon increases or decreases in our stock price over the three-year <br>vesting period<br>|

---

**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](#i9b1fd1ad317847e0938f74c3bc18e448_3604) of this proxy statement.

COMPENSATION DISCUSSION AND ANALYSIS

Detailed Discussion and Analysis

Base Salary<br>

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.

Company and Individual Ratings<br>

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.

**Additional Factors (accomplishments and/or shortcomings)** 

In connection with determining our 2025 company rating, the MDCC made positive and negative adjustments based on factors not

anticipated when the company's original goals for 2025 were established. By design, potential adjustments are capped at ±10% (or

±15 points), not to exceed total achievement of 150%, and used by the MDCC to address and highlight important achievements and

shortcomings. 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. Positive

adjustments were related to the acceleration of povetacicept in IgAN, advancing additional, novel molecules and therapies beyond

what was planned, and significant progress in market shaping activity for a pipeline product. Overall, the MDCC increased our

company rating by 6.75 points for these positive additional accomplishments, which was offset by a three-point reduction related to

challenges associated with three programs. As a result, our final company rating was increased by 3.75 points to a total of 131 points

(rounded).

2025 Individual Performance Ratings - Overview

The MDCC evaluates each executive's individual performance on a "results-based, values-tempered" basis, which takes into account

not only "what" was accomplished, but "how" it was accomplished. The results-based component evaluates the executive officer's

performance in their individual role and as a leader of our company in achieving our objectives. The possible individual results-based

performance ratings are "not building," "building," "strong," or "leading." The values-tempered component of the individual evaluations

builds upon our company core values: "uncompromising commitment to patients;" "innovation is our lifeblood;" "fearless pursuit of

excellence" and "we wins" and are considered along with our leadership competencies, which reflect our core values and leadership

behaviors that we believe lead to successful execution of our strategy and continued emphasis on innovation and collaboration. We

expect all employees to demonstrate our company core values and leadership behaviors in all aspects of job performance. We further

expect that our executives will be stewards of our company culture, and the performance ratings assigned to them incorporate our

MDCC's assessment of the strength of their leadership with respect to, and demonstration of, values-based behavior. This evaluation

results in ratings of "inconsistent demonstration," "living the values," or "exemplary demonstration." The possible individual

performance ratings under this program are as set forth in the following table:

COMPENSATION DISCUSSION AND ANALYSIS

Detailed Discussion and Analysis

The 2025 results-based rating recommendation for each NEO, other than our CEO, is the combined result of the MDCC members' own

observations and a review of the executive's role in the accomplishment of the corporate goals under our annual plan and

recommendations regarding the executive, the latter of which are provided to the MDCC by our CEO and is made on the basis of her

independent assessment of each executive officer's performance. The MDCC, Dr. Kewalramani and Dr. Leiden discussed each

recommendation at length, on both an individual and comparative basis. Upon completion of these discussions, the MDCC determined

and approved the results-based rating for each executive. The final results-based ratings reflect the recommendations of Dr.

Kewalramani and Dr. Leiden, the opinions of MDCC members (based on the executive's contributions and the MDCC members'

interactions with the executive), as well as other factors. The MDCC gave Dr. Kewalramani's recommendations greater weight when

determining the behaviors-based rating than when determining the results-based rating, as the behaviors-based rating is pertinent to

the executive's daily interactions in carrying out their duties. Furthermore, the MDCC believes that, in her role as CEO, Dr. Kewalramani

had greater visibility than the MDCC members into the quality of these interactions. Taking into account all of the factors raised in the

discussion and the assigned individual performance rating, the MDCC assigns two individual modifiers or performance factors for each

NEO, one for the cash bonus award and one for the annual equity awards. Each NEO's annual cash bonus is determined by their target

bonus multiplied by their individual performance factor and the annual corporate performance factor determined by the MDCC based

on their assessment of corporate goal achievement as summarized on page [60](#i1b549f248e974347b59d0410e55fc6cb_38389). Each NEO's equity award is determined by their target

equity award for their level, multiplied by their individual equity modifier, reflecting performance and potential. While the individual

ratings are not 100% objective, we view them as critical factors indicative of management success and crucial to achieving the more

objective goals discussed above. The results-based and behaviors-based evaluations for our CEO are based on a similar assessment

of individual performance by our MDCC and the independent directors. Individual performance can significantly affect an executive

officer's cash and equity compensation.

The individual incentive targets are established and reviewed by the MDCC based on available data about Peer Group company

compensation (as supplemented for Mr. Wagner, as described above). For 2025, Dr. Kewalramani's individual incentive target

remained at 150% of her base salary. The individual incentive target for Dr. Bozic, Mr. Sachdev and Dr. Tatsis remained at 90% of their

respective base salary during 2025. Mr. Wagner's individual incentive target increased to 100% from 90% of his base salary in

connection with his transition to the role of our Chief Operating and Financial Officer on July 1, 2025. The resulting target annual cash

bonuses of our executives approximate the median target annual cash bonuses for comparable executives at our Peer Group

companies (as supplemented for Mr. Wagner, as described above).

Company performance factors are determined annually and range from 0% to 150%. The possible individual ratings and

corresponding individual performance factor ranges for our executive officers in 2025 are set forth in the table below:

---

On the basis of the factors described above, the MDCC approved individual performance factors and annual bonus awards for each of

the NEOs other than our CEO for which the MDCC recommended, and our independent directors approved, on account of 2025

performance, as set forth in the table below. Mr. Arbuckle did not receive an annual bonus for 2025 due to his retirement on July 1,

2025. ---

Annual Equity Awards<br>

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.

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
|  | **Target value** | **Performance Rating-Based Equity Modifiers** | **Performance Rating-Based Equity Modifiers** | **Performance Rating-Based Equity Modifiers** | **Performance Rating-Based Equity Modifiers** | **Performance Rating-Based Equity Modifiers** |
| | **Target value** | **Not Building** | **Building** | **Strong** | **Leading** | **Leading Exemplary** |
| CEO | $13500000 | —% | 50% - 86.5% | 86.5% - 113.5% | 100% - 127% | 113.5% - 127% |
| COO | $4750000 | —% | 50% - 80% | 80% - 120% | 100% - 150% | 120% - 150% |
| EVP (excluding the COO) | $4000000 | —% | 50% - 80% | 80% - 120% | 100% - 150% | 120% - 150% |

---

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 75<sup>th</sup> 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.

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:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| **Award**<br>**Year** | **Below**<br>**Threshold**<br>| **Threshold** | **Target** | **Max**  | **Results** | **Results** |

(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%.

| **2023** | Complete enrollment in a pivotal program | Achieved | 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.

Other Compensation Arrangements<br>

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.

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 DISCUSSION AND ANALYSIS

Detailed Discussion and Analysis

Compensation Practices<br>

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](#i019559ecf92a4439b83477525d7801ca_0-0-1-1-344315) of this proxy statement. The guidelines for our NEOs are set forth in the following

table:

---

| | |
|:---|:---|
| **Employee** | **Minimum Shareholding Requirement** |
| CEO | 6X base salary |
| EVPs | 4X base salary |

---

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.

COMPENSATION DISCUSSION AND ANALYSIS

Detailed Discussion and Analysis

**Risk Mitigation Factors**

We believe that our annual cash bonus and long-term equity compensation programs, which account for most of our executive officers'

compensation, contain appropriate risk mitigation factors, as summarized above under *"Compensation Governance Practices."*

**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.

(1)Pursuant to applicable SEC rules, the grant-date fair values of the equity awards granted in February 2025 for 2024 performance are included in

2025 compensation. The equity awards granted in February 2026 to Dr. Kewalramani, Mr. Wagner, Dr. Bozic, Mr. Sachdev and Dr. Tatsis for 2025

performance are discussed in the Compensation Discussion and Analysis section and are not reflected in the Summary Compensation Table above.

(2)In connection with Mr. Arbuckle's retirement from the Company, the MDCC determined to treat his outstanding grants as eligible for the Company's

Career Employment Provision. This resulted in the revaluation of certain awards under applicable accounting guidance. Accordingly, the amounts for

Mr. Arbuckle in 2025 consist of (i) $6,235,429 representing the grant-date fair values of the equity awards granted to Mr. Arbuckle in February 2025

for 2024 performance, and (ii) $3,106,498 representing the incremental fair value associated with the awards that were revalued.

Bonus

Pursuant to applicable SEC rules, the annual cash bonuses earned by our NEOs are included under the caption "Non-Equity Incentive

Plan Compensation."

Stock Awards

The amounts set forth under the caption "Stock Awards" in the table above represent the grant-date fair value of awards granted during

the applicable fiscal year, together, in the case of Mr. Arbuckle, with the incremental fair value associated with the awards held by him

that were modified in 2025. In general, the equity awards reflected in the Summary Compensation Table for a specific year reflect

equity grants made earlier in that calendar year based on the executive's performance in the year prior to the year the equity grants are

awarded. Because a majority of executive compensation is in the form of equity awards, the total compensation for each NEO for 2025

as reflected in the table above is significantly affected by such executive's performance during 2024.

COMPENSATION AND EQUITY TABLES

Summary Compensation Table

The annual "Stock Awards" for 2025, 2024, and 2023 consist of PSU awards and time-vested RSU awards granted in February of each

year. In each of 2025, 2024, and 2023, the financial PSU awards had grant-date values of 100% of the fair value of the target shares,

respectively, in accordance with U.S. GAAP (with fair values determined based on the value of our common stock on the date of grant

of the applicable award). In 2025, 2024, and 2023, the non-financial PSU awards had grant-date values of 50% of the fair value of the

target shares in accordance with U.S. GAAP. For each of these awards, the grant-date fair values were based on the probable outcome

of the performance conditions associated with the awards. If the grant-date fair value of the financial and non-financial PSU awards had

been 200% of the fair value of the target shares, the table above would have included the following amounts:

**(1)*Annual Cash Bonus.*** The amounts in the "Estimated Possible Payouts Under Non-Equity Incentive Plan Awards" column represent the minimum

threshold, target, and maximum amounts that our NEOs were eligible to earn pursuant to our 2025 annual cash bonus program. Actual amounts paid

to each of the NEOs under this program for 2025 performance are set forth in the *Summary Compensation Table* above. Mr. Arbuckle was not

awarded an annual cash bonus for the 2025 performance year (which, if awarded, would have been paid in February 2026).

financial PSU awards (2a) was based on 100% of the fair value of the target shares and the grant date value of the non-financial PSU awards (2b)

was based on a fair value of 50% of the target shares in 2025. These awards vest if, and only if, performance objectives are achieved, as described

in the footnotes to the table *Outstanding Equity Awards at Fiscal Year-End for 2025* below.

**(3)*Time-Based RSUs.*** The amounts in the "All Other Stock Awards: Number of Shares of Stock or Units" column represent the number of time-based

RSUs granted to the NEOs in 2025, which generally vest annually over three years.

Arbuckle's outstanding awards previously awarded to him in 2023 and 2024 in connection with his retirement from the Company. See footnote (2) to

the Summary Compensation Table above.

The amounts in the table above do not include any life insurance payments or disability insurance payments that the executive or the

executive's estate may receive under existing insurance policies. The assumptions underlying the calculations in the table include:

• No amounts have been included with respect to stock options held by NEOs as all of their outstanding stock options are fully vested.

• The value of each share of restricted stock unit that would be accelerated or continue to vest, in each case in the circumstances

described below, equals $453.36 per share (the closing price of a share of our common stock on the last trading day of 2025). The

value of any PSUs that have not been certified as to the level of performance by the MDCC as of December 31, 2025 are reported

above assuming target performance (100%).

• Our board of directors would elect not to pay a pro rata portion of an executive's target bonus for the year of termination in cases

where the executive's employment is terminated voluntarily by the executive (for any reason, including retirement) or for cause,

under our policy that cash bonuses are payable only to employees who are otherwise eligible and who remain employed by us on

the date of bonus payment, typically in February of the next year.

SUMMARY OF TERMINATION AND CHANGE OF CONTROL BENEFITS

• Our board of directors would have assigned the same 2025 individual and company performance ratings on December 31, 2025 as

they assigned in the first quarter of 2026.

• No NEO who has met the age and service requirements for retirement has provided the required notice for a termination of

employment to qualify as a retirement as of December 31, 2025.

The actual amounts that the current NEOs could receive in the future as a result of a termination of employment would likely differ

materially from the amounts set forth above as a result of, among other things, changes in our stock price, changes in the officers' base

salary, target bonus amounts and actual bonus amounts, and the vesting and grants of additional equity awards.

In connection with Mr. Arbuckle's retirement on July 1, 2025, the MDCC determined to treat his outstanding grants as eligible for the

company's Career Employment Provision. This resulted in 9,369 shares underlying RSUs and 19,199 shares underlying PSUs (at target

or earned shares, as applicable) being deemed to have satisfied the relevant service vesting condition associated with such awards.

Mr. Arbuckle did not otherwise receive any severance or other termination-related benefits in connection with his retirement.

EMPLOYMENT CONTRACTS AND CHANGE OF

CONTROL ARRANGEMENTS

Executive Severance Arrangements

We have entered into agreements and maintain plans that require us to provide to our NEOs cash compensation, benefits, and/or

acceleration of the vesting of equity awards in the event of termination of employment under specified circumstances. In addition to the

agreements described below, outstanding options granted under our stock and option plans provide that, in the event of certain

changes of control, either appropriate provision for the continuation of all then-outstanding options must be made, or the vesting of

those options will be accelerated and they will become fully exercisable immediately prior to such change of control. All options held by

our NEOs are fully vested and, as a result, would not have their vesting accelerated as a result of change in control or otherwise. As

described below, the benefits that are to be provided in connection with a change of control are subject to a "double trigger." 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. The

following descriptions are qualified in the entirety by the agreements with the NEOs, which have been filed with the SEC.

In addition to the benefits described below, under programs applicable to all employees, if an NEO dies while an employee, their estate

and/or beneficiaries would receive full acceleration of all outstanding equity awards, and if an NEO's employment is terminated due to

disability, he or she would receive full acceleration of equity grants. None of our current employment agreements provide for a so-

called Section 4999 excise tax "gross-up," and we have a policy against providing so-called Section 4999 excise tax "gross-up" in the

future.

Agreements with Reshma Kewalramani

Dr. Kewalramani's written employment agreement provides that she is entitled to receive compensation as determined by our board of

directors and is eligible to receive the benefits generally made available to our executives. In addition, Dr. Kewalramani has agreed not

to engage in specified competitive activities for 12 months after her employment with us terminates.

If (i) Dr. Kewalramani's employment is terminated by us without cause or (ii) she terminates her employment for good reason, she would

be entitled to receive, subject to limited exceptions:

---

| | |
|:---|:---|
| Severance Payment:<br>A) | 200% of the sum of her (i) base salary at the time of termination and (ii) target bonus for the year in which her <br>employment is terminated<br>|

| Severance Payment:<br> C) | A pro-rated bonus for the year in which the termination occurs based on her target bonus for the year in <br>which the termination occurs<br>|
| Equity: | Outstanding options and RSUs unvested on the termination date would receive partial vesting based on the <br>portion of the award(s) that would have vested during the 12-month period following the termination date.  |
| Employee Benefits: | Continuation of certain employee benefits for up to 18 months |

---

If (i) Dr. Kewalramani's employment is terminated by us without cause or (ii) she terminates her employment for good reason, in each

case, within 90 days prior to or 12 months after a change of control of the company, she would instead be entitled to receive:

| Severance Payment:<br> C) | All cash incentive awards earned by Dr. Kewalramani, if not yet paid |
| Equity: | Full vesting of all outstanding options and restricted stock unit awards (using target or earned shares, as <br>applicable, for performance-based awards) |
| Employee Benefits: | Continuation of certain employee benefits for up to 18 months |

---

Severance payments to Dr. Kewalramani in connection with a change of control may be reduced to increase their value to

Dr. Kewalramani if such payments would be subject to an excise tax under Section 4999 of the Code.

EMPLOYMENT CONTRACTS AND CHANGE OF CONTROL ARRANGEMENTS

If Dr. Kewalramani's employment is terminated as a result of death or disability, she would be entitled to receive:

• a pro-rated bonus for the year of employment termination;

• for equity awards not covered by the company-wide equity program described above, vesting of any options and restricted stock

unit awards then unvested at the time of termination.

Agreements with Dr. Bozic, Dr. Tatsis and Mr. Wagner

**Employment Agreements**

The terms and conditions of Dr. Bozic's, Dr. Tatsis' and Mr. Wagner's employment are governed by written employment contracts that

were entered into, in the case of Dr. Bozic, in October 2022, in the case of Dr. Tatsis, at the time she became Chief Regulatory and

Quality Officer, and, in the case of Mr. Wagner, at the time of his appointment as Chief Operating and Financial Officer. Each of these

officer's employment agreements provides that he or she is entitled to receive compensation as determined by the MDCC or our board

of directors and is eligible to receive the benefits generally made available to our executives. In addition, each officer has agreed not to

engage in specified competitive activities for a period of one year after the termination of his or her employment with us. Mr. Arbuckle

had been party to such an agreement prior to the termination of his employment with us.

Under each employment agreement, (i) if the officer's employment is terminated without cause or (ii) the officer terminates his or her

employment with us for good reason within 30 days of the event giving rise to his or her right to terminate for good reason, subject to

notice and cure provisions, he or she would be entitled to receive:

| Employee Benefits: | Continuation of certain employee benefits for up to 12 months |

---

In addition, if Mr. Wagner's employment is terminated as a result of death or disability, he would be entitled to receive:

• a pro-rated bonus for the year of employment termination

• for equity awards not covered by the company-wide equity program described above, vesting of any options and restricted stock

unit awards then unvested at the time of termination

**Change of Control Agreements**

We have a change of control agreement with each of Dr. Bozic, Dr. Tatsis and Mr. Wagner that was entered into, in the case of Dr.

Bozic, in October 2022, in the case of Dr. Tatsis, at the time she became Chief Regulatory and Quality Officer, and, in the case of Mr.

Wagner, at the time of his appointment as Chief Operating and Financial Officer. Under this agreement and the executive's equity

agreements, if we terminate the employment of the officer without cause on a date within the 90 days prior to or the 12 months after a

change of control or any of these individuals terminates his or her employment within 30 days of an event giving rise to a right to

terminate for good reason, subject to notice and cure provisions, and the event occurs on a date within the 90 days prior to or the

12 months after a change of control, he or she would be entitled to receive:

agreement prior to the termination of his employment with us.

PAY RATIO

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, the SEC requires annual disclosure of the ratio of the annual

total compensation of our CEO to that of our median employee.

In 2025, Dr. Kewalramani's annual total compensation, as reported in the Summary Compensation Table, was $21,144,261 and the

median of the annual total compensation of all employees of the company (other than our Chief Executive Officer) was $264,487. The

ratio of annual total compensation for Dr. Kewalramani to that of our median employee's annual total compensation was approximately

80:1.

We identified the median employee as of October 1, 2024, using target total annual compensation in 2024, which included:

• Base salary

• Target cash bonus

• Target long-term equity awards

Our measure of compensation for identifying the median employee was consistently applied to all employees (converting all non-USD

currencies into USD based on 12-month foreign exchange rates for the 12-month period ending October 1, 2024). We do not believe

that there have been any material changes in our employee population or compensation arrangements that would require us to change

our median employee for 2025.

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

and the methodology described above. Because the SEC rules for identifying the median compensated employee and calculating the

pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain

exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices, the pay ratio reported by

other companies may not be comparable to the pay ratio reported above, as other companies may have different employment and

compensation practices and may utilize different methodologies, exclusions, estimates, and assumptions in calculating their own

pay ratios.

of 2021, through the last trading day for the applicable fiscal year in the table. TSR is calculated by dividing the sum of the cumulative amount of

dividends for the measurement period, assuming dividend reinvestment, and the difference between our share price at the end and the beginning of

the measurement period by our share price at the beginning of the measurement period.

(6)This column represents the TSR of the NBI, our selected peer group, which is the same peer group used for purposes of Item 201(e) of Regulation

S-K from December 31, 2020, the last trading day before the start of 2021, through the last trading day for the applicable fiscal year in the table,

assuming reinvestment of dividends and weighted according to the respective companies' stock market capitalization at the beginning of each

period for which a return is indicated.

(7)This column reflects net income (loss) as reported for each year in our Annual Report on Form 10-K. In 2024, we had a net loss of $536 million, which

reflected our strong operating results offset by $4.4 billion of AIPR&D expense related to our acquisition of Alpine.

(8)This column reflects net product revenue as reported for each year in our Annual Report on Form 10-K. For purposes of the table above, we have

selected net product revenue as the financial performance measure representing the most important financial performance measure used to link

executive compensation actually paid to our financial performance in the most recently completed fiscal year. Please see the *Compensation* 

*Discussion and Analysis* section beginning on page [49](#ia256593921614749816b7ebfc4f483d4_121) of this proxy statement for additional information.

OTHER INFORMATION

communications relating to ordinary or routine business affairs, personal grievances, or matters as to which we tend to receive

repetitive or duplicative communications.

Householding of Annual Meeting Materials

Some banks, brokers and other nominee record holders may be participating in the practice of "householding" proxy materials. This

means that only one copy of our Notice of Internet Availability of Proxy Materials or proxy statement and annual report may have been

sent to multiple shareholders in your household. We will promptly deliver a separate copy of these documents to you if you write or call

our corporate secretary at the following address or phone number: 50 Northern Avenue, Boston, Massachusetts 02210, telephone

(617) 341-6100. If you want to receive separate copies of the proxy materials in the future, or if you are receiving multiple copies and

would like to receive only one copy for your household, you should contact your bank, broker, or other nominee record holder, or you

may contact us at the above address and phone number.

Solicitation

We will bear the cost of soliciting proxies, including expenses in connection with preparing this proxy statement and hosting the annual

meeting. We have retained Sodali & Co to assist in the solicitation of proxies at an estimated cost of approximately $25,000. Proxies

also may be solicited by our directors and employees by mail, by telephone, in person or otherwise. Neither directors nor employees

will receive additional compensation for solicitation efforts. In addition, we will request banks, brokers and other custodians, nominees

and fiduciaries to forward proxy material to the beneficial owners of common stock and to obtain voting instructions from the beneficial

owners. We will reimburse those firms for their reasonable expenses in forwarding proxy materials and obtaining voting instructions.

Forward-Looking Statements

This proxy statement contains forward-looking statements. Forward-looking statements are not purely historical and may be

accompanied by words such as "anticipates," "may," "forecasts," "expects," "intends," "plans," "potentially," "believes," "seeks,"

"estimates," and other words and terms of similar meaning. Such statements may include, without limitation, statements regarding: our

research and development strategy, including with respect to delivering transformative medicines at high rates of speed and success

and enabling leadership in selected disease areas, our marketed products and pipeline therapies, particularly with respect to benefits,

safety, and expansion into younger patients and additional geographies, potential regulatory submissions and approvals, expected

clinical development plans and timing, continued significant investment in internal and external innovation, and expectations regarding

the ongoing diversification of our commercialization efforts, our beliefs, expectations, plans and expectations with respect to the

potential near-term launch of povetacicept for IgAN and with respect to the continued commercial progress for CASGEVY for the

treatment of SCD and TDT, ALYFTREK for the treatment of CF, and JOURNAVX for the treatment of moderate-to-severe acute pain,

including with respect to continued prescription and revenue growth for JOURNAVX in 2026, expectations for the data that will be

generated by ongoing and planned clinical trials and the ability to use that data to advance compounds, continue development or

support regulatory filings, or accelerate regulatory approval, plans to share data from the interim analysis of inaxaplin for the treatment

of AMKD in late 2026 or early 2027, expectations to complete enrollment in both Phase 3 clinical trials evaluating suzetrigine for the

treatment of diabetic peripheral neuropathy by the end of 2026, beliefs regarding the temporary postponement in the Phase 1/2/3 study

of zimislecel for the treatment of T1D and plans for the ongoing internal manufacturing analysis, and expectations to complete the

Phase 2 portion of the clinical trial evaluating povetacicept for the treatment of pMN and initiate the Phase 3 portion in mid-2026. While

we believe the forward-looking statements contained in this proxy statement are accurate, these forward-looking statements represent

our beliefs only as of the date of this proxy statement. There are a number of risks and uncertainties that are difficult to predict and

could cause actual events or results to differ materially from those indicated by such forward-looking statements. Those risks and

uncertainties include, among other things, that the company's expectations regarding its future financial performance may be incorrect

(including because one or more of the company's assumptions underlying its expectations may not be realized), that regulatory

submissions or approvals may not occur on the anticipated timeline, or at all, that we may be unable to launch and commercialize

povetacicept as a treatment for IgAN or to further successfully commercialize ALYFTREK as a treatment for CF, JOURNAVX as a

treatment for acute pain, and CASGEVY as a treatment for SCD and TDT, that data from clinical trials or preclinical testing, especially if

based on a limited number of patients, may not be indicative of final results, that data from the company's developmental programs

may not support registration or further development of its potential medicines in a timely manner, or at all, due to safety, efficacy or

other reasons, that regulatory authorities may not approve regulatory filings for our pipeline products on a timely basis, or at all, that

external factors may have different or more significant impacts on the company's business or operations than the company currently

expects, and other risks listed under the heading "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended December

31, 2025, filed with the SEC on February 13, 2026, and available through the company's website at www.vrtx.com. You should not

place undue reliance on these statements, or any data presented. We disclaim any obligation to update the information contained in

this proxy statement as new information becomes available, except as required by law.

FREQUENTLY ASKED QUESTIONS

REGARDING THE ANNUAL MEETING

What is the Purpose of the Annual Meeting?<br>

At the annual meeting, shareholders will act upon the matters outlined in the Notice of Annual Meeting of Shareholders. These include:

• The election of directors;

• The ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for 2026;

• To hold an advisory vote on our 2025 named executive officer compensation;

• To approve our 2026 Stock and Option Plan; and

• A shareholder proposal regarding shareholder rights to act by written consent.

Management, members of our board and representatives of Ernst & Young LLP are expected to attend the annual meeting and be

available to respond to appropriate questions from shareholders.

What is a Proxy?<br>

It is your legal designation of another person to vote the stock you own in the manner you direct. That other person is called a proxy. If

you designate someone as your proxy in a written document, that document also is called a proxy or a proxy card. The board of

directors has designated Jeffrey Leiden, Reshma Kewalramani, Joy Liu, and Omar White to serve as proxies at the annual meeting.

What is a Proxy Statement?<br>

It is a document that provides certain information about a company and matters to be voted upon at a meeting of shareholders. The

rules of the SEC and other applicable laws require us to give you, as a shareholder, the information in this proxy statement and our

Annual Report when we are soliciting your vote.

Why did I receive a "Notice of Internet Availability of Proxy Materials" but no <br>proxy materials?<br>

We are distributing our proxy materials to shareholders via the Internet under the "Notice and Access" approach permitted by rules of

the SEC. This approach provides a timely and convenient method of accessing the materials and voting. On or about April 2, 2026, we

will begin mailing a "Notice of Internet Availability of Proxy Materials" to shareholders. This notice includes instructions on how to

access our notice of annual meeting of shareholders, this proxy statement and our Annual Report on Form 10-K for the year ended

December 31, 2025 and how to vote your shares. The Notice of Internet Availability of Proxy Materials also contains instructions on how

to receive a paper copy of the proxy materials and our Annual Report, if you prefer.

What is the Difference between a Shareholder of Record and a Shareholder Who Holds <br>Stock in Street Name?<br>

**Shareholders of Record.** If your shares are registered in your name with our transfer agent, Computershare, you are a shareholder of

record with respect to those shares, and the Notice of Internet Availability of Proxy Materials was sent directly to you

by Computershare.

**Street Name Holders.** If you hold your shares in an account at a bank, broker or other nominee, then you are the beneficial owner of

shares held in "street name." The Notice of Internet Availability of Proxy Materials was forwarded to you by your bank, broker or other

nominee. As a beneficial owner, you have the right to direct your bank or broker how to vote the shares held in your account.

How do I Register to Attend the Virtual Annual Meeting on the Internet?<br>

If you are a registered shareholder (i.e., you hold your shares through our transfer agent, Computershare), you do not need to register

in advance to attend the virtual annual meeting. Please follow the instructions on the Notice of Internet Availability of Proxy Materials or

the proxy card that you received.

If you hold your shares in street name through an intermediary, such as a bank or broker, you must register and obtain a control

How Many Shares Must be Represented in Order to Hold the Annual Meeting?<br>

In order for us to conduct the annual meeting, holders of a majority of the shares entitled to vote as of the close of business on the

record date must be present in person or by proxy. This constitutes a quorum. Shares present virtually during the annual meeting will

be considered shares of common stock represented in person at the meeting. If you are a shareholder of record, your shares are

counted as present if you properly vote by Internet, telephone, return a proxy card by mail or if you attend the annual meeting online. If

you are the beneficial owner of shares held in street name, you must follow the instructions of your bank or broker in order to direct

them how to vote the shares held in your account or obtain a legal proxy to vote online at the annual meeting. Abstentions and broker

non-votes will be counted as present for purposes of establishing a quorum. If a quorum is not present, we will adjourn the annual

meeting until a quorum is obtained.

FREQUENTLY ASKED QUESTIONS REGARDING THE ANNUAL MEETING

Are My Shares Voted if I Do Not Provide a Proxy?<br>

If you are a shareholder of record and do not provide a proxy, you must attend the annual meeting in order to vote. If you hold shares

through an account with a bank or broker, your shares may be voted by the bank or broker on certain matters if you do not provide

voting instructions. Banks and brokers have the authority under applicable rules to vote shares on routine matters for which their

customers do not provide voting instructions. The ratification of Ernst & Young LLP as our independent registered public accounting

firm is considered a routine matter. Each of the other proposals, including the election of directors, the advisory vote with respect to our

executive compensation program, the approval of our 2026 Stock and Option plan, and the shareholder proposal are considered non-

routine, and banks and brokers cannot vote shares without instruction on those matters. Shares that banks and brokers are not

authorized to vote on those matters are counted as "broker non-votes" and will have no effect on the results of those votes.

What Vote is Required to Approve Each Proposal and How are Votes Counted?<br>

Proposal No. 1: Election of Directors

To be elected, the number of votes cast "FOR" each director nominee must exceed the number of votes cast "AGAINST" that nominee.

Abstentions will have no effect on the results of this vote. Our Corporate Governance Principles contain procedures to be followed in

the event that one or more directors do not receive a majority of the votes cast "FOR" their election.

Proposal No. 2: Ratification of the Appointment of Independent Registered Public Accounting Firm

To be approved, this proposal must receive an affirmative vote from shareholders present personally or represented by proxy at the

annual meeting representing a majority of the votes cast on the proposal. Abstentions will have no effect on the results of this vote.

Proposal No. 3: Advisory Vote to Approve Named Executive Officer Compensation

To be approved, this proposal must receive an affirmative vote from shareholders present personally or represented by proxy at the

annual meeting representing a majority of the votes cast on the proposal. Abstentions will have no effect on the results of this vote.

Proposal No. 4: Approval of 2026 Stock and Option Plan

To be approved, this proposal must receive an affirmative vote from shareholders present personally or represented by proxy at the

annual meeting representing a majority of the votes cast on the proposal. Abstentions will have no effect on the results of this vote.

Proposal No. 5: Shareholder Proposal Regarding Shareholder Right to Act by Written Consent

To be approved, this proposal must receive an affirmative vote from shareholders present personally or represented by proxy at the

annual meeting representing a majority of the votes cast on the proposal. Abstentions will have no effect on the results of this vote.

Where Can I Find More Information About My Voting Rights as a Shareholder?<br>

The SEC has an informational website that provides shareholders with general information about how to cast their vote and why voting

should be an important consideration for shareholders. You may access that website at sec.gov/spotlight/proxymatters.shtml.

APPENDIX A: VERTEX PHARMACEUTICALS

INCORPORATED 2026 STOCK

AND OPTION PLAN

**1. DEFINED TERMS**

<u>Exhibit A</u>, which is incorporated by reference, defines certain terms used in the Plan and includes certain operational rules

related to those terms.

**2. PURPOSE**

The Plan has been established to advance the interests of the Company by providing for the grant to Participants of Stock and

Stock-based Awards.

**3. ADMINISTRATION**

The Plan will be administered by the Administrator. The Administrator has discretionary authority, subject only to the express

provisions of the Plan, to administer and interpret the Plan and any Awards; to determine eligibility for and grant Awards; to determine

the exercise price, base value from which appreciation is measured, or purchase price, if any, applicable to any Award, to determine,

modify, accelerate or waive the terms and conditions of any Award; to determine the form of settlement of Awards (whether in cash,

shares of Stock, other Awards or other property); to prescribe forms, rules and procedures relating to the Plan and Awards; and to

otherwise do all things necessary or desirable to carry out the purposes of the Plan or any Award. Determinations of the Administrator

made with respect to the Plan or any Award are conclusive and bind all persons.

**4. SHARE POOL; LIMITS ON AWARDS UNDER THE PLAN**

**(a)<u>Number of Shares</u>.** Subject to adjustment as provided in Section 7(b) below, the maximum number of shares of

Stock that may be delivered in satisfaction of Awards under the Plan is 6,400,000 shares, plus (i) the number of shares of Stock that as

of the Effective Date are subject to awards under the Company's Amended and Restated 2013 Stock and Option Plan (the "2013 Plan")

and that on or after the Effective Date 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 fungible share ratio set forth

therein, and (ii) the number of shares of Stock that as of the Effective Date remain available for issuance under the 2013 Plan (which, in

the case of (i) and (ii), shall not exceed 13,232,240 shares, prior to the application of the fungible share ratio set forth in the 2013 Plan)

(such aggregate number of shares of Stock, the "Share Pool"). Up to the total number of shares of Stock from the Share Pool may be

delivered in satisfaction of ISOs, but nothing in this Section 4(a) will be construed as requiring that any, or any fixed number of, ISOs be

granted under the Plan. For purposes of determining the share limits under this Section 4(a), (i) each share of Stock subject to a Stock

Option or SAR will count as one share and each share of Stock subject to any other Award will count as 1.66 shares, and (ii) the

number of shares of Stock delivered in satisfaction of Awards will be determined (A) by reducing the Share Pool by the number of

shares of Stock withheld by the Company in payment of the exercise price or purchase price of an Award or an award granted under

the 2013 Plan or in satisfaction of tax withholding requirements with respect to an Award or an award granted under the 2013 Plan, (B)

by reducing the Share Pool by the full number of shares covered by a SAR any portion of which is settled in Stock (and not only the

number of shares of Stock delivered in settlement), and (C) by increasing the Share Pool by any shares of Stock underlying any portion

of an Award or an award granted under the 2013 Plan that is settled in cash or that expires, becomes unexercisable, terminates or is

forfeited to or repurchased by the Company without the issuance (or retention, in the case of Restricted Stock or Unrestricted Stock) of

Stock. For the avoidance of doubt, the Share Pool will not be increased by any shares of Stock delivered under the Plan that are

subsequently repurchased using proceeds directly attributable to Stock Option exercises. The limits set forth in this Section 4(a) will be

construed to comply with the applicable requirements of Section 422.

**(b)** **<u>Substitute Awards</u>.** The Administrator may grant Substitute Awards under the Plan. To the extent consistent with

the requirements of Section 422 and the regulations thereunder and other applicable legal requirements (including applicable stock

exchange requirements), shares of Stock delivered in respect of Substitute Awards will be in addition to and will not reduce the Share

Pool. Notwithstanding the foregoing or anything in Section 4(a) to the contrary, if any Substitute Award is settled in cash or expires,

becomes unexercisable, terminates or is forfeited to or repurchased by the Company without the delivery (or retention, in the case of

Restricted Stock or Unrestricted Stock) of Stock, the shares of Stock previously subject to such Award will not increase the Share Pool

or otherwise be available for future grant under the Plan. The Administrator will determine the extent to which the terms and conditions

of the Plan apply to Substitute Awards, if at all; provided, however, that Substitute Awards will not be subject to the limits described in

Section 4(d) below.

**(c)** **<u>Type of Shares</u>.** Stock delivered by the Company under the Plan may be authorized but unissued Stock, treasury

Stock or previously issued Stock acquired by the Company. Fractional shares of Stock may be delivered under the Plan subject to

such rules and procedures as determined by the Administrator from time to time.

**(d)** **<u>Director Limits</u>.** Notwithstanding anything to the contrary under the Plan, the aggregate value of all compensation

granted or paid to any Director with respect to any calendar year, including Awards granted under the Plan and cash fees or other

compensation paid by the Company to such Director outside of the 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 Awards based on the grant date fair value in accordance

with the Accounting Rules and assuming a maximum payout, to the extent applicable. For the avoidance of doubt, the limitation in this

Section 4(d) will 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.

**5. ELIGIBILITY AND PARTICIPATION**

The Administrator will select Participants from among Employees and Directors of, and consultants and advisors to, the Company and

its affiliates; provided, however, that, subject to such express exceptions, if any, as the Administrator may establish, eligibility shall be

further limited to those persons as to whom the use of a Form S-8 registration statement is permissible. Eligibility for ISOs is limited to

individuals who are employees of the Company or of a "parent corporation" or "subsidiary corporation" of the Company as those terms

are defined in Section 424 of the Code. Eligibility for Stock Options, other than ISOs, and SARs is limited to individuals described in the

first sentence of this Section 5 who are providing direct services on the date of grant of the Award to the Company or to a subsidiary of

the Company that would be described in the first sentence of Section 1.409A-1(b)(5)(iii)(E) of the Treasury Regulations.

**6. RULES APPLICABLE TO AWARDS**

**(a)<u>All Awards</u>.**

**(1**)**<u>Award Provisions</u>**. The Administrator will determine the terms and conditions of all Awards, subject to the

limitations provided herein. No term of an Award shall provide for automatic "reload" grants of additional Awards upon the exercise of

an Option or SAR. By accepting (or, under such rules as the Administrator may prescribe, being deemed to have accepted) an Award,

the Participant agrees (or will be deemed to have agreed) to the terms and conditions of the Award and the Plan. Notwithstanding any

provision of the Plan to the contrary, Substitute Awards may contain terms and conditions that are inconsistent with the terms and

conditions specified herein, as determined by the Administrator.

**(2)** **<u>Term of Plan</u>.** No Awards may be made after May 13, 2036 but previously granted Awards may continue

beyond that date in accordance with their terms.

**(3)** **<u>Transferability</u>.** Neither ISOs nor, except as the Administrator otherwise expressly provides in accordance

with the third sentence of this Section 6(a)(3), other Awards may be transferred other than by will, by the laws of descent and

distribution or pursuant to a validly issued domestic relations order. During a Participant's lifetime, ISOs and, except as the

Administrator otherwise expressly provides in accordance with the third sentence of this Section 6(a)(3), SARs and NSOs may be

exercised only by the Participant. The Administrator may permit the gratuitous transfer (i.e., transfer not for value) of Awards other than

ISOs, including for estate planning purposes, subject to applicable securities and other laws and such terms and conditions as the

Administrator may determine; for avoidance of doubt, no Award may be transferred for consideration to a third party.

**(4)** **<u>Vesting; Exercisability</u>.** The Administrator will determine the time or times at which an Award vests or

becomes exercisable and the terms and conditions on which a Stock Option or SAR remains exercisable. Without limiting the

foregoing, the Administrator may at any time accelerate the vesting and/or exercisability of an Award (or any portion thereof),

regardless of any adverse or potentially adverse tax or other consequences resulting from such acceleration, including in connection

with a Covered Transaction or other transaction or event. Unless the Administrator expressly provides otherwise, however, the

following rules will apply if a Participant's Employment ceases:

**(A)**Immediately upon the cessation of the Participant's Employment, each unvested Stock Option

and SAR (or portion thereof)that is then held by the Participant or by the Participant's permitted transferees, if any, will cease

to be exercisable and will terminate and each other unvested Award (or portion thereof) that is then held by the Participant or

by the Participant's permitted transferees, if any, will be forfeited.

**(B)**Subject to (C) and (D) below, each Stock Option and SAR (or portion thereof) held by the

Participant or the Participant's permitted transferees, if any, immediately prior to the cessation of the Participant's

Employment, to the extent then vested and exercisable, will remain exercisable for the lesser of (i) a period of ninety (90) days

following such cessation of Employment or (ii) the period ending on the latest date on which such Stock Option or SAR could

have been exercised without regard to this Section 6(a)(4), and will thereupon immediately terminate.

**(C)**Subject to (D) below, each Stock Option and SAR (or portion thereof) held by a Participant or the

Participant's permitted transferees, if any, immediately prior to the cessation of the Participant's Employment due to the

Participant's death or by the Company due to the Participant's Disability, to the extent then vested and exercisable, will remain

exercisable for the lesser of (i) the one-year period ending on the first anniversary of such cessation of Employment or (ii) the

period ending on the latest date on which such Stock Option or SAR could have been exercised without regard to this Section

6(a)(4), and will thereupon immediately terminate.

**(D)**All Awards (whether or not vested or exercisable) held by a Participant or the Participant's

permitted transferees, if any, immediately prior to the cessation of the Participant's Employment will immediately terminate

upon (i) such cessation of Employment if the termination is for Cause or occurs in circumstances that in the determination of

the Administrator would have constituted grounds for the Participant's Employment to be terminated for Cause (in each case,

without regard to the lapsing of any required notice or cure periods in connection therewith) or (ii) to the maximum extent

permitted under applicable law, the Participant's violation of any non-competition, non-solicitation, no-hire, non-

disparagement, confidentiality, invention assignment, or other restrictive covenant in favor of the Company or any of its

affiliates by which the Participant is bound.

**(5)<u>Recovery of Compensation; Other Policies</u>.** The Administrator may provide in any case that any

outstanding Award (whether or not vested or exercisable), the proceeds from the exercise or disposition of any Award or Stock

acquired under any Award, and any other amounts received in respect of any Award or Stock acquired under any Award will be

subject to forfeiture and disgorgement to the Company, with interest and other related earnings, if the Participant to whom the Award

---

| | |
|:---|:---|
| VERTEX PHARMACEUTICALS INCORPORATED - 2026 Proxy Statement | A-3 |

---

was granted is not in compliance with any provision of the Plan or any applicable Award or violates any non-competition, non-

solicitation, no-hire, non-disparagement, confidentiality, invention assignment or other restrictive covenant by which the Participant is

bound. Each Award will be subject to any policy of the Company or any of its affiliates that relates to trading on non-public information

and permitted transactions with respect to shares of Stock, including limitations on hedging and pledging. In addition, each Award will

be subject to recoupment to the extent a Participant is or becomes subject to the Company's Policy for Recoupment of Incentive

Compensation, effective October 2, 2023, the Company's March 2013 Recoupment Policy, or any other policy of the Company or any

of its affiliates that provides for forfeiture, disgorgement, or clawback with respect to incentive compensation that includes Awards

under the Plan (the "Clawback Policies"). Each Participant, by accepting or being deemed to have accepted an Award under the Plan,

agrees (or will be deemed to have agreed) to the terms of this Section 6(a)(5), and to the Clawback Policies, if applicable, and further

agrees (or will be deemed to have further agreed) to cooperate fully with the Administrator, and to cause any and all permitted

transferees of the Participant to cooperate fully with the Administrator, to effectuate any forfeiture, recoupment or disgorgement

described in this Section 6(a)(5). Neither the Administrator nor the Company nor any other person, other than the Participant and the

Participant's permitted transferees, if any, will be responsible for any adverse tax or other consequences to a Participant or the

Participant's permitted transferees, if any, that may arise in connection with this Section 6(a)(5).

**(6)** **<u>Taxes</u>.** The grant of an Award and the issuance, delivery, vesting and retention of Stock, cash or other

property under an Award are conditioned upon the full satisfaction by the Participant of all tax and other withholding requirements with

respect to the Award under applicable laws. The Administrator will prescribe such rules for the withholding of taxes and other amounts

with respect to any Award as it deems necessary. Without limiting the foregoing, the Company or any affiliate of the Company will have

the authority and the right to deduct or withhold (by any means set forth herein or in an Award agreement), or require a Participant to

remit to the Company or an affiliate of the Company, an amount sufficient to satisfy all U.S. and non-U.S. federal, state and local income

tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to participation in the Plan

and any Award hereunder and legally applicable to the Participant and required by law to be withheld (including, any amount deemed

by the Company, in its discretion, to be an appropriate charge to the Participant even if legally applicable to the Company or any

affiliate of the Company). Subject to applicable laws, the Administrator, in its sole discretion, may hold back shares of Stock from an

Award or permit a Participant to tender previously-owned shares of Stock in satisfaction of tax or other withholding requirements (but

not in excess of the maximum withholding amount consistent with the Award being subject to equity accounting treatment under the

Accounting Rules). Any amounts withheld pursuant to this Section 6(a)(6) will be treated as though such amounts had been paid

directly to the applicable Participant. In addition, the Company may, to the extent permitted by law, deduct any such tax and other

withholding amounts from any payment of any kind otherwise due to a Participant from the Company or any of its affiliates.

**(7)** **<u>Dividend Equivalents</u>**. The Administrator may provide for the payment of amounts (on terms and subject

to such restrictions and conditions established by the Administrator, including providing for the reinvestment of such amounts in the

form of additional Awards) in lieu of cash dividends or other cash distributions with respect to Stock subject to an Award, whether or not

the holder of such Award is otherwise entitled to share in the actual dividend or distribution in respect of such Award; provided,

however, that (a) 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) shall be subject to the same risk of forfeiture that applies to the underlying

Award and (b) no dividends or dividend equivalents shall be payable with respect to Stock Options or SARs. Any entitlement to

dividend equivalents or similar entitlements will be established and administered either consistent with an exemption from, or in

compliance with, the applicable requirements of Section 409A.

**(8)** **<u>Rights Limited</u>.** Nothing in the Plan or any Award will be construed as giving any person the right to be

granted an Award or to continued employment or service with the Company or any of its affiliates, or any rights as a shareholder except

as to shares of Stock actually delivered under the Plan. The loss of existing or potential profit in any Award will not constitute an

element of damages in the event of a termination of a Participant's Employment for any reason, even if the termination is in violation of

an obligation of the Company or any of its affiliates to the Participant.

**(9)** **<u>Coordination with Other Plans</u>.** Shares of Stock and/or Awards under the Plan may be issued or granted

in tandem with, or in satisfaction of or substitution for, other Awards under the Plan or awards made under other compensatory plans or

programs of the Company or any of its affiliates. For example, but without limiting the generality of the foregoing, awards under other

compensatory plans or programs of the Company or any of its affiliates may be settled in Stock (including, without limitation,

Unrestricted Stock) under the Plan if the Administrator so determines, in which case the shares delivered will be treated as awarded

under the Plan (and will reduce the Share Pool).

**(10)** **Reserved.**

**(11)** **<u>Section 409A</u>.**

**(A)**Without limiting the generality of Section 11(a) below, each Award will contain such terms as the

Administrator determines and will be construed and administered, such that the Award either qualifies for an exemption from

the requirements of Section 409A or satisfies such requirements.

**(B)**Notwithstanding anything to the contrary in the Plan or any Award agreement, the Administrator

may unilaterally amend, modify or terminate the Plan or any outstanding Award, including but not limited to changing the form

of the Award, if the Administrator determines that such amendment, modification or termination is necessary or desirable to

avoid the imposition of any additional tax, interest or penalty under Section 409A.

**(C)**If a Participant is determined on the date of the Participant's termination of Employment to be a

"specified employee" within the meaning of that term under Section 409A(a)(2)(B) of the Code, then, with regard to any

---

| | |
|:---|:---|
| A-4 | VERTEX PHARMACEUTICALS INCORPORATED - 2026 Proxy Statement |

---

payment that is considered nonqualified deferred compensation under Section 409A, to the extent applicable, payable on

account of a "separation from service", such payment will be made or provided on the date that is the earlier of (i) the first

business day following the expiration of the six-month period measured from the date of such "separation from service" and

(ii) the date of the Participant's death (the "Delay Period"). Upon the expiration of the Delay Period, all payments delayed

pursuant to this Section 6(a)(11)(C) (whether they would have otherwise been payable in a single lump sum or in installments

in the absence of such delay) will be paid, without interest, on the first business day following the expiration of the Delay

Period in a lump sum and any remaining payments due under the Award will be paid in accordance with the normal payment

dates specified for them in the applicable Award agreement.

**(D)**For purposes of Section 409A, each payment made under the Plan or any Award will be treated

as a separate payment.

**(E)**With regard to any payment considered to be nonqualified deferred compensation under

Section 409A, to the extent applicable, that is payable upon a change in control of the Company or other similar event, to the

extent required to avoid the imposition of any additional tax, interest or penalty under Section 409A, no amount will be payable

unless such change in control constitutes a "change in control event" within the meaning of Section 1.409A-3(i)(5) of the

Treasury Regulations.

**(b)<u>Stock Options and SARs</u>**.

**(1)<u>Time and Manner of Exercise</u>**. Unless the Administrator expressly provides otherwise, no Stock Option

or SAR will be deemed to have been exercised until the Administrator receives a notice of exercise in a form acceptable to the

Administrator that is signed by the appropriate person and accompanied by any payment required under the Award. The

Administrator may limit or restrict the exercisability of any Stock Option or SAR in its discretion, including in connection with any

Covered Transaction. Any attempt to exercise a Stock Option or SAR by any person other than the Participant will not be given effect

unless the Administrator has received such evidence as it may require that the person exercising the Award has the right to do so. If

on the date the term of an NSO expires or on the last date such NSO is exercisable in accordance with Section 6(a)(4), the fair market

value of a share of Stock exceeds the exercise price per share of the NSO, then the NSO shall automatically be exercised with respect

to all then vested Shares underlying such NSO and, upon such automatic exercise, such NSO shall immediately terminate. In such

case, payment of the exercise price for the shares of Stock as to which such NSO is being exercised, and all tax withholding

requirements, shall be satisfied by the withholding of unrestricted shares of Stock otherwise deliverable upon such exercise as set

forth in Section 6(b)(3) below. As a result of such net exercise, the Participant shall receive (i) the number of shares of Stock

underlying the portion of the NSO so being exercised, less (ii) such whole number of shares of Stock (rounded up to the nearest

share) that is equal to (A) the aggregate exercise price for the portion of the NSO that is so being exercised plus the amount of all

applicable tax withholdings associated with such exercise divided by (B) the fair market value of a share of Stock on the date of

exercise.

**(2)<u>Exercise Price</u>.** The exercise price (or the base value from which appreciation is to be measured) per

share of each Award requiring exercise must be no less than 100% (in the case of an ISO granted to a 10-percent shareholder within

the meaning of Section 422(b)(6) of the Code, 110%) of the Fair Market Value of a share of Stock, determined as of the date of grant of

the Award, or such higher amount as the Administrator may determine in connection with the grant.

**(3)<u>Payment of Exercise Price</u>.** Where the exercise of an Award (or portion thereof) is to be accompanied by

payment, payment of the exercise price must be made by cash or check acceptable to the Administrator or, if so permitted by the

Administrator and if legally permissible, (i) through the delivery of previously acquired unrestricted shares of Stock, or the withholding of

unrestricted shares of Stock otherwise deliverable upon exercise, in either case, that have a fair market value equal to the exercise

price; (ii) through a broker-assisted cashless exercise program acceptable to the Administrator; (iii) by other means acceptable to the

Administrator; or (iv) by any combination of the foregoing permissible forms of payment. The delivery of previously acquired shares in

payment of the exercise price under clause (i) above may be accomplished either by actual delivery or by constructive delivery through

attestation of ownership, subject to such rules as the Administrator may prescribe.

**(4)<u>Maximum Term</u>.** The maximum term of Stock Options and SARs must not exceed 10 years from the date

of grant (or five years from the date of grant in the case of an ISO granted to a 10-percent shareholder described in Section 6(b)(2)

above).

**(5)<u>No Repricing</u>.** Except in connection with a corporate transaction involving the Company (which term

includes, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger,

consolidation, split-up, spin-off, combination or exchange of shares) or as otherwise contemplated by Section 7 below, the Company

may not, without obtaining shareholder approval, (i) amend the terms of outstanding Stock Options or SARs to reduce the exercise

price or base value of such Stock Options or SARs, (ii) cancel outstanding Stock Options or SARs 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) cancel 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.

**7. EFFECT OF CERTAIN TRANSACTIONS**

**(a)<u>Covered Transactions</u>**. Except as otherwise expressly provided in an Award agreement or other agreement or by

the Administrator, the following provisions will apply in the event of a Covered Transaction:

---

| | |
|:---|:---|
| VERTEX PHARMACEUTICALS INCORPORATED - 2026 Proxy Statement | A-5 |

---

**(1)<u>Assumption or Substitution</u>.** If the Covered Transaction is one in which there is an acquiring or surviving

entity, the Administrator may provide for (i) the assumption or continuation of some or all outstanding Awards or any portion thereof or

(ii) the grant of new awards in substitution therefor by the acquiror or survivor or an affiliate of the acquiror or survivor.

**(2)<u>Cash-Out of Awards</u>.** Subject to Section 7(a)(5) below, the Administrator may provide for payment (a

"cash-out"), with respect to some or all Awards or any portion thereof (including only the vested portion thereof, with the unvested

portion terminating as provided in Section 7(a)(4) below), equal in the case of each applicable Award or portion thereof to the excess, if

any, of (i) the fair market value of one share of Stock multiplied by the number of shares of Stock subject to the Award or such portion,

minus (ii) the aggregate exercise or purchase price, if any, of such Award or such portion thereof (or, in the case of a SAR, the

aggregate base value above which appreciation is measured), in each case, on such payment and other terms and subject to such

conditions (which need not be the same as the terms and conditions applicable to holders of Stock generally) as the Administrator

determines, including that any amounts paid in respect of such Award in connection with the Covered Transaction be placed in escrow

or otherwise made subject to such restrictions as the Administrator deems appropriate. For the avoidance of doubt, if the per share

exercise or purchase price (or base value) of an Award or portion thereof is equal to or greater than the fair market value of one share

of Stock, as determined in connection with the Covered Transaction, such Award or portion may be cancelled with no payment due

hereunder or otherwise in respect thereof.

**(3)<u>Acceleration of Certain Awards</u>.** Subject to Section 7(a)(5) below, the Administrator may provide that any

Award requiring exercise will become exercisable, in full or in part, and/or that the delivery of any shares of Stock remaining deliverable

under any outstanding Award of Stock Units (including Restricted Stock Units and Performance Awards to the extent consisting of

Stock Units) will be accelerated, in full or in part, in each case on a basis that gives the holder of the Award a reasonable opportunity,

as determined by the Administrator, following the exercise of the Award or the delivery of the shares, as the case may be, to participate

as a shareholder in the Covered Transaction.

**(4)<u>Termination of Awards upon Consummation of Covered Transaction</u>.** Except as the Administrator may

otherwise determine, each Award will automatically terminate (and in the case of outstanding shares of Restricted Stock, will

automatically 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 pursuant to Section 7(a)(1) above, 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.

**(5)<u>Additional Limitations</u>.** Any share of Stock and any cash or other property or other award delivered

pursuant to Section 7(a)(1), Section 7(a)(2) or Section 7(a)(3) above with respect to an Award may, in the discretion of the

Administrator, contain such restrictions, if any, as the Administrator deems appropriate, including to reflect any performance or other

vesting conditions to which the Award was subject and that did not lapse (and were not satisfied) in connection with the Covered

Transaction. For purposes of the immediately preceding sentence, a cash-out under Section 7(a)(2) above or an acceleration under

Section 7(a)(3) above will not, in and of itself, be treated as the lapsing (or satisfaction) of a performance or other vesting condition. In

the case of Restricted Stock that does not vest and is not forfeited in connection with the Covered Transaction, the Administrator may

require that any amounts delivered, exchanged or otherwise paid in respect of such Stock in connection with the Covered Transaction

be placed in escrow or otherwise made subject to such restrictions as the Administrator deems appropriate to carry out the intent of the

Plan.

**(6)<u>Uniform Treatment</u>.** For the avoidance of doubt, the Administrator need not treat Participants or Awards

(or portions thereof) in a uniform manner, and may treat different Participants and/or Awards differently, in connection with a Covered

Transaction.

**(b)<u>Changes in and Distributions with Respect to Stock.</u>**

**(1)<u>Basic Adjustment Provisions</u>.** In the event of a stock dividend, extraordinary cash dividend, stock split

or combination of shares (including a reverse stock split), recapitalization, reorganization, merger, consolidation, combination,

exchange of shares, liquidation, spin-off, split-up or other similar change in the Company's capital structure that constitutes an equity

restructuring within the meaning of the Accounting Rules, the Administrator shall make appropriate adjustments to the Share Pool, and

shall make appropriate adjustments to the number and kind of shares of stock or securities underlying Awards then outstanding or

subsequently granted, any exercise or purchase prices (or base values) relating to Awards and any other provision of Awards affected

by such change.

**(2)<u>Certain Other Adjustments</u>.** The Administrator may also make adjustments of the type described in

Section 7(b)(1) above to take into account distributions to shareholders other than those provided for in Sections 7(a) and 7(b)(1)

above, or any other event, if the Administrator determines that adjustments are appropriate to avoid distortion in the operation of the

Plan or any Award, having due regard for the qualification of ISOs under Section 422 and the requirements of Section 409A, to the

extent applicable.

**(3)<u>Continuing Application of Plan Terms</u>.** References in the Plan to shares of Stock will be construed to

include any stock or securities resulting from an adjustment pursuant to this Section 7.

**8. LEGAL CONDITIONS ON DELIVERY OF STOCK**

The Company will not be obligated to deliver any shares of Stock pursuant to the Plan or to remove any restriction from shares

of Stock previously delivered under the Plan until: (i) the Company is satisfied that all legal matters in connection with the issuance and

---

| | |
|:---|:---|
| A-6 | VERTEX PHARMACEUTICALS INCORPORATED - 2026 Proxy Statement |

---

delivery of such shares have been addressed and resolved; (ii) if the outstanding Stock is at the time of delivery listed on any stock

exchange or national market system, the shares to be delivered have been listed or authorized to be listed on such exchange or

system upon official notice of issuance; and (iii) all conditions of the Award have been satisfied or waived. The Company may require,

as a condition to the exercise of an Award or the delivery of shares of Stock under an Award, such representations or agreements as

counsel for the Company may consider appropriate to avoid violation of the Securities Act of 1933, as amended, or any applicable

state or non-U.S. securities law. Any Stock delivered to Participants under the Plan will be evidenced in such manner as the

Administrator determines appropriate, including book-entry registration or delivery of stock certificates. In the event that the

Administrator determines that stock certificates will be issued in connection with Stock issued under the Plan, the Administrator may

require that such certificates bear an appropriate legend reflecting any restriction on transfer applicable to such Stock, and the

Company may hold the certificates pending the lapse of the applicable restrictions.

**9. AMENDMENT AND TERMINATION**

The Administrator may at any time or times amend the Plan or any outstanding Award for any purpose which may at the time

be permitted by applicable law, and may at any time terminate the Plan as to any future grants of Awards; provided, however, that

except as otherwise expressly provided in the Plan or the applicable Award, the Administrator may not, without the Participant's

consent, alter the terms of an Award so as to affect materially and adversely the Participant's rights under the Award, unless the

Administrator expressly reserved the right to do so in the Plan or at the time the applicable Award was granted. Any amendments to

the Plan will be conditioned upon shareholder approval only to the extent, if any, such approval is required by applicable law (including

the Code) or stock exchange requirements, as determined by the Administrator. For the avoidance of doubt, without limiting the

Administrator's rights hereunder, no adjustment to any Award pursuant to the terms of Section 7 or Section 12 will be treated as an

amendment requiring a Participant's consent.

**10. OTHER COMPENSATION ARRANGEMENTS**

The existence of the Plan or the grant of any Award will not affect the right of the Company or any of its affiliates to grant any

person bonuses or other compensation in addition to Awards under the Plan.

**11. MISCELLANEOUS**

**(a)** **<u>Waiver of Jury Trial</u>.** By accepting or being deemed to have accepted an Award under the Plan, each Participant

waives (or will be deemed to have waived), to the maximum extent permitted under applicable law, any right to a trial by jury in any

action, proceeding or counterclaim concerning any rights under the Plan or any Award, or under any amendment, waiver, consent,

instrument, document or other agreement delivered or which in the future may be delivered in connection therewith, and agrees (or will

be deemed to have agreed) that any such action, proceedings or counterclaim will be tried before a court and not before a jury. By

accepting (or being deemed to have accepted) an Award under the Plan, each Participant certifies that no officer, representative, or

attorney of the Company or any of its affiliates has represented, expressly or otherwise, that the Company would not, in the event of any

action, proceeding or counterclaim, seek to enforce the foregoing waivers. Notwithstanding anything to the contrary in the Plan,

nothing herein is to be construed as limiting the ability of the Company and a Participant to agree to submit any disputes arising under

the terms of the Plan or any Award made hereunder to binding arbitration or as limiting the ability of the Company to require any

individual to agree to submit such disputes to binding arbitration as a condition of receiving an Award hereunder.

**(b)** **<u>Limitation of Liability</u>.** Notwithstanding anything to the contrary in the Plan or any Award, none of the Company,

nor any of its affiliates, nor the Administrator, nor any person acting on behalf of the Company, any of its affiliates, or the Administrator,

will be liable to any Participant, to any permitted transferee, to the estate or beneficiary of any Participant or any permitted transferee, or

to any other person by reason of any acceleration of income, any additional tax, or any penalty, interest or other liability asserted by

reason of the failure of an Award to satisfy the requirements of Section 422 or Section 409A or by reason of Section 4999 of the Code,

or otherwise asserted with respect to any Award.

**(c)** **<u>Unfunded Plan</u>.** The Company's obligations under the Plan are unfunded, and no Participant will have any right to

specific assets of the Company in respect of any Award. Participants will be general unsecured creditors of the Company with respect

to any amounts due or payable under the Plan.

**12. ESTABLISHMENT OF SUB-PLANS**

The Administrator may at any time and from time to time (including before or after an Award is granted) establish, adopt, or

revise any rules and regulations as it may deem necessary or advisable to administer the Plan for Participants based outside of the U.S.

and/or subject to the laws of countries other than the U.S., including by establishing one or more sub-plans, supplements or

appendices under the Plan or any Award agreement for the purpose of complying or facilitating compliance with non-U.S. laws or

taking advantage of tax favorable treatment or for any other legal or administrative reason determined by the Administrator. Any such

sub-plan, supplement or appendix may contain, in each case, (i) such limitations on the Administrator's discretion under the Plan and

(ii) such additional or different terms and conditions, as the Administrator deems necessary or desirable and will be deemed to be part

of the Plan but will apply only to Participants within the group to which the sub-plan, supplement or appendix applies (as determined by

the Administrator); provided, however, that no sub-plan, supplement or appendix, rule or regulation established pursuant to this

provision shall increase the Share Pool.

**13. GOVERNING LAW**

**(a)** **<u>Certain Requirements of Corporate Law</u>.** Awards and shares of Stock will be granted, issued and administered

consistent with the requirements of applicable Massachusetts law relating to the issuance of stock and the consideration to be received

---

| | |
|:---|:---|
| VERTEX PHARMACEUTICALS INCORPORATED - 2026 Proxy Statement | A-7 |

---

therefor, and with the applicable requirements of the stock exchanges or other trading systems on which the Stock is listed or entered

for trading, in each case as determined by the Administrator.

**(b)** **<u>Other Matters</u>.** Except as otherwise provided by the express terms of an Award agreement or under a sub-plan

described in Section 12 above, the domestic substantive laws of the Commonwealth of Massachusetts govern the provisions of the

Plan and of Awards under the Plan and all claims or disputes arising out of or based upon the Plan or any Award under the Plan or

relating to the subject matter hereof or thereof without giving effect to any choice or conflict of laws provision or rule that would cause

the application of the domestic substantive laws of any other jurisdiction.

**(c)** **<u>Jurisdiction</u>.** Subject to Section 11(a) and except as may be expressly set forth in an Award agreement, by

accepting (or being deemed to have accepted) an Award, each Participant agrees or will be deemed to have agreed to (i) submit

irrevocably and unconditionally to the jurisdiction of the federal and state courts located within the geographic boundaries of the United

States District Court for the District of Massachusetts for the purpose of any suit, action or other proceeding arising out of or based

upon the Plan or any Award; (ii) not commence any suit, action or other proceeding arising out of or based upon the Plan or any Award,

except in the federal and state courts located within the geographic boundaries of the United States District Court for the District of

Massachusetts; and (iii) waive, and not assert, by way of motion as a defense or otherwise, in any such suit, action or proceeding, any

claim that the Participant is not subject personally to the jurisdiction of the above-named courts, that the Participant's property is

exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue

of the suit, action or proceeding is improper or that the Plan or any Award or the subject matter thereof may not be enforced in or by

such court.

purposes of the Plan.

the Securities Exchange Act of 1934, as amended (the "Act"), becomes a beneficial owner, as such term is used in Rule 13d-3

promulgated under the Act, of securities of the Company representing more than 50% of the combined voting power of the outstanding

---

**"Disability":** A disability entitling a Participant to benefits under the Company's long-term disability program, as in effect from

time to time. With regard to any payment considered to be nonqualified deferred compensation under Section 409A, to the extent

applicable, that is payable upon a cessation of a Participant's Employment due to Disability, to avoid the imposition of an additional tax,

interest or penalty under Section 409A, no amount will be payable unless such Disability constitutes a disability or becoming disabled

within the meaning of Section 1.409A-3(i)(4) of the Treasury Regulations.

**"Effective Date":** The date the Plan is approved by shareholders of the Company.

**"Employee":** Any person who is employed by the Company or any of its affiliates.

**"Employment":** A Participant's employment or other service relationship with the Company or any of its affiliates.

Employment will be deemed to continue, unless the Administrator otherwise determines, so long as the Participant is employed by, or

otherwise is providing services in a capacity described in Section 5 of the Plan to, the Company or any of its affiliates. If a Participant's

employment or other service relationship is with any affiliate of the Company and that entity ceases to be an affiliate of the Company,

the Participant's Employment will be deemed to have terminated when the entity ceases to be an affiliate of the Company unless the

Participant transfers Employment to the Company or one of its remaining affiliates. For purposes of the Plan, an approved leave of

absence due to a temporary disability or that constitutes a standard paid leave under Company policies as in effect from time to time

shall not be deemed to be a termination of Employment, except as the Administrator may otherwise expressly provide or except as

otherwise provided by law.

Notwithstanding the foregoing, in construing the provisions of any Award relating to the payment of "nonqualified deferred

compensation" (subject to Section 409A) upon a termination or cessation of Employment, references to termination or cessation of

employment, separation from service, retirement or similar or correlative terms will be construed to require a "separation from

service" (as that term is defined in Section 1.409A-1(h) of the Treasury Regulations, after giving effect to the presumptions contained

therein) from the Company and from all other corporations and trades or businesses, if any, that would be treated as a single "service

recipient" with the Company under Section 1.409A-1(h)(3) of the Treasury Regulations. The Company may, but need not, elect in

writing, subject to the applicable limitations under Section 409A, any of the special elective rules prescribed in Section 1.409A-1(h) of

the Treasury Regulations for purposes of determining whether a "separation from service" has occurred. Any such written election will

be deemed a part of the Plan.

**"Fair Market Value":** As of a particular date, (i) the mean between the highest and lowest quoted selling prices for a share of

Stock reported on the Nasdaq Market System (or any other national securities exchange on which the Stock is then listed) for that date

or, if there were no sales on such date, on the next preceding date within a reasonable period (as determined in the sole discretion of

the Administrator) on which there were sales or (ii) in the event that the Stock is not traded on a national securities exchange, the fair

market value of a share of Stock determined by the Administrator consistent with the rules of Section 422 and Section 409A to the

extent applicable.

**"ISO":** A Stock Option intended to be an "incentive stock option" within the meaning of Section 422. Each Stock Option

granted pursuant to the Plan will be treated as providing by its terms that it is to be an NSO unless, as of the date of grant, it is

expressly designated as an ISO in the applicable Award agreement.

**"NSO":** A Stock Option that is not intended to be an "incentive stock option" within the meaning of Section 422.

**"Participant":** A person who is granted an Award under the Plan.

**"Performance Award":** An Award subject to performance vesting conditions, which may include Performance Criteria.

**"Performance Criteria":** Specified criteria, other than the mere continuation of Employment or the mere passage of time, the

satisfaction of which is a condition for the grant, exercisability, vesting or full enjoyment of an Award. A Performance Criterion and any

targets with respect thereto need not be based upon an increase, a positive or improved result or avoidance of loss and may be

applied, without limitation, to a Participant individually, to a group of individual Participants, or to a business unit or division of the

Company or to the Company as a whole. A Performance Criterion may also be based on individual performance and/or subjective

performance criteria (or any combination of any of the criteria described in this definition). The Administrator may provide that one or

more of the Performance Criteria applicable to such Award will be adjusted in a manner to reflect events (for example, but without

limitation, acquisitions or dispositions) occurring during the performance period that affect the applicable Performance Criterion or

Criteria.

**"Plan":** The Vertex Pharmaceuticals Incorporated 2026 Stock and Option Plan, as from time to time amended and in effect.

**"Restricted Stock":** Stock subject to restrictions requiring that it be forfeited, redelivered or offered for sale to the Company

if specified performance or other vesting conditions are not satisfied.

**"Restricted Stock Unit":** A Stock Unit that is, or as to which the delivery of Stock or of cash in lieu of Stock is, subject to the

satisfaction of specified performance or other vesting conditions.

**"SAR":** A right entitling the holder upon exercise to receive an amount (payable in cash or in shares of Stock of equivalent

value) equal to the excess of the Fair Market Value of the shares of Stock subject to the right over the base value from which

appreciation under the SAR is to be measured.

**"Section 409A":** Section 409A of the Code and the regulations thereunder.

**"Section 422":** Section 422 of the Code and the regulations thereunder.

the value of Stock in the future.
