DEAR SHAREHOLDERS:

2015
A Letter from our Executive Chairman and
Chief Executive Officer

Dear Shareholders:

2023 was a transformative year for Vertex. We extended our leadership in cystic fibrosis (“CF”), expanded into new disease areas with CASGEVY regulatory approvals and commercial launches for severe sickle cell disease (“SCD”) and transfusion-dependent beta thalassemia (“TDT”) in multiple regions, and continued the rapid advancement of tremendous successour broad pipeline, which offers the potential for multiple commercial launch opportunities in disease areas outside of CF over the next few years. We believe that these important advances in 2023, combined with our continued excellent financial performance, fuel a new era of medical and commercial diversification for Vertex and more importantly,significant value creation for patients and shareholders alike.

Net product revenues from our CF medicines grew to $9.87 billion in 2023, representing an 11% increase from 2022. We continued to invest significantly in innovation — both internal and external — to support our differentiated research and development (“R&D”) approach, focused on validated targets that address causal human biology, biomarkers that translate from bench to bedside, efficient development and regulatory pathways, and product candidates with transformative potential. Our differentiated R&D strategy has continued to deliver. We have obtained approvals for the thousands of people acrossfirst CRISPR/Cas9 gene-edited cell therapy in the world for the treatment of SCD and TDT and we have also delivered positive Phase 3 results for VX-548, our novel NaV1.8 pain signal inhibitor in acute pain, and for our triple combination of vanzacaftor/tezacaftor/deutivacaftor in CF. Our programs in neuropathic pain, APOL1-mediated kidney disease, and type 1 diabetes have all passed the proof-of-concept stage and represent additional multi-billion-dollar market potential. In total, our clinical-stage pipeline now spans 10 disease areas and multiple modalities, including small molecules, oligonucleotides, and cell and genetic therapies.

Along with cystic fibrosis (CF). Our dream has beendeveloping and commercializing transformative medicines for people with serious diseases, we continue to create a company that has the scientific wherewithalsupport patients, our local communities, and our employees. Last year, Vertex celebrated its 15th Global Day of Service, with participation by 60% of employees contributing nearly 8,300 hours of volunteer work across more than 125 projects with 73 non-profit groups. In addition, Vertex and the financial strengthVertex Foundation provided more than $42 million in charitable donations, with a focus on education, innovation, health, and our local communities. We remain committed to consistently discoverrecruiting, retaining, and developdeveloping highly talented employees from a diverse range of backgrounds, promoting our employees’ continued well-being and professional development, and nurturing our unique culture, which has enabled us to deliver multiple transformative medicines to patients. Our efforts continue to be recognized externally, and in 2023, Vertex was named to Fortune 100 Best Companies to Work For® 2023, Forbes Best Employers for Diversity 2023, and 2023 PEOPLE® Companies that can treatCare.

In summary, consistent execution of our R&D and corporate strategy continues to deliver strong and durable financial results, setting up significant and sustainable long-term growth for the underlying cause of serious diseases, like CF.business. We are making that dream a reality one patient at a time.


Four years ago, there were no medicines to treat the underlying cause of CF. Today, we have two medicines approved for approximately 25,000 patients worldwide - about a third of all patients with this disease. Much of this progress was achieved in 2015 with the approval of ORKAMBI® in the United States and Europe and label expansions for KALYDECO®. Despite this progress, we are far from done. The people of Vertex are motivated, not by what we have accomplished, but by what we have to do to help alltreating more people with CF around the world and otherare working to translate the historic regulatory approvals for CASGEVY in SCD and TDT into real world patient benefit. We are also preparing for additional potential near-term submissions, approvals, and launches, including for vanzacaftor/tezacaftor/deutivacaftor in CF and VX-548 in acute pain, both of which have the potential to dramatically improve patient lives and represent significant opportunities for Vertex. In parallel, we are progressing the next wave of innovation and look forward to bringing additional first-in-class or best-in-class medicines to people living with serious diseases. Looking ahead,This is an extraordinarily exciting time for Vertex and, as Executive Chairman and Chief Executive Officer, we have a clear path to reach that goal and are committed to delivering.

In 2015, we significantly advancedthe continued successful execution of our pipeline in CF, bringing two next-generation correctors intoserial innovation strategy to drive exceptional results for patients, the clinic, in-licensing an investigational ENaC inhibitor from Parion Sciences, Inc.,medical community, and establishing a collaboration with CRISPR Therapeutics to discover new approaches to treating a number of diseases, including CF. We also diversified our pipeline of new medicines, and now have multiple medicines in the clinic for a variety of serious diseases outside of CF; diseases in which our understanding of the underlying biology is strong.

Entering 2016, we are on a path toward sustained earnings and revenue growth, and over the last few years, have transitioned from a development-stage organization to a global commercial-stage biotech company with two approved medicines in markets across the world. We increased CF net product revenues to nearly $1 billion in 2015 and have a strong balance sheet.

In summary, we are truly a different company today than we were four years ago - and even at the beginning of last year. We are in a position of incredible opportunity and responsibility - to patients and to you, our shareholders. What excites me most about our future is where the science is taking us - the transformative nature of the medicines we are discovering and developing to address even more serious diseases. And how our unique business model has positioned us to deliver earnings while also, continuing to invest in our pipeline to develop additional transformative medicines.

All of us at Vertex are humbled and inspired by the CF community, the patients, families and their caregivers who we hear from every day. Thank you for the support you’ve provided to help us get to where we are today, and for inspiring our vision of helping people around the world with serious diseases live healthy, full lives.

Sincerely,

Jeffrey M. Leiden, M.D., Ph.D.

SUMMARY

2023 was a transformational year for the company marked by significant advances in research, development, and commercialization, across the entire company. Our strategy of investing in scientific innovation to developingcreate transformative medicines for people with serious diseases. Overdiseases, with a focus on specialty markets, is delivering. Not only did we extend our leadership in cystic fibrosis (“CF”) by reaching more people with CF than ever before, but we also diversified commercially with the last severallaunch of CASGEVY, our gene-edited cell therapy for the treatment of sickle cell disease (“SCD”) and transfusion-dependent beta thalassemia (“TDT”). In addition, we substantially progressed our broad and diverse pipeline, prepared for additional potential near-term launch opportunities in CF and acute pain, and further strengthened our financial profile.

Today, our CF medicines are collectively being used to treat nearly three-quarters of the approximately 92,000 people with CF in North America, Europe and Australia. Our CF medicines are used by people in over 60 countries, and TRIKAFTA/KAFTRIO is now reimbursed or accessible in more than 40 of those countries. As we look to the future, we expect to continue to grow our CF business through label expansions, approvals of new medicines and expanded reimbursement. We also continue to serially innovate in CF, as demonstrated by our recent announcement of positive data from three pivotal studies evaluating our next-generation triple combination of vanzacaftor/tezacaftor/deutivacaftor (the “vanzacaftor triple”). This new triple combination regimen has demonstrated the potential to provide clinical benefits over and above TRIKAFTA, and also has the advantages of a once-daily dosing regimen and a lower royalty burden. We continue to invest in serial innovation in our CFTR modulator program and have already discovered the next-generation CFTR modulators, with the goal of creating medicines that deliver even more benefit by bringing more people with CF to carrier levels of sweat chloride, which we believe is the pivotal milestone in the journey toward restoring quality and quantity of life for people living with CF. In addition, we are pursuing a nebulized messenger RNA (“mRNA”) therapy, VX-522, designed for the more than 5,000 people with CF who cannot benefit from our CFTR modulators.

In SCD and TDT, CASGEVY is now approved for people 12 years of age and older in the United States (“U.S.”), the European Union (“E.U.”), the United Kingdom (“U.K.”), the Kingdom of Saudi Arabia (“Saudi Arabia”), and the Kingdom of Bahrain (“Bahrain”). We estimate approximately 35,000 people with severe SCD and TDT could be eligible for CASGEVY in the U.S. and Europe, with additional eligible people in Saudi Arabia and Bahrain. Pursuant to our global launch strategy, we have met or exceededbeen educating physicians, patients, caregivers, payors, and policymakers about the significant disease burden of SCD and TDT and the availability of CASGEVY as a potentially curative treatment option. We are also actively engaged with treatment centers, policymakers, and payors to ensure that eligible people have broad access to this transformative therapy. Additionally, we continue to study CASGEVY in younger age groups and work on preclinical assets for myeloablative conditioning agents that would have milder side effects, which could broaden the eligible patient population.

In our goals, building onpain program, earlier this year, we announced positive results from our leadership positionPhase 3 clinical trials evaluating VX-548, a selective, peripherally-acting small molecule inhibitor of the NaV1.8 sodium channel, in the treatment of cystic fibrosis,moderate-to-severe acute pain and our plans to submit for regulatory approval in the U.S. by mid-2024. If approved, VX-548 will be the first of a new class of medicines for acute pain in over 20 years. With an estimated 80 million patients prescribed medicines for moderate-to-severe acute pain in the U.S. every year, representing over 1 billion calendar days of treatment, we believe acute pain represents a multi-billion dollar market opportunity. We also recently announced positive results from the Phase 2 clinical trial evaluating VX-548 in diabetic peripheral neuropathy (“DPN”), a type of peripheral neuropathic pain (“PNP”), and our intention to advance VX-548 into pivotal development for DPN. We also began a Phase 2 clinical trial for patients suffering from lumbosacral radiculopathy, another type of PNP. As with acute pain, our goal is to secure a broad PNP indication for VX-548. There are an estimated 10 million patients prescribed medicines for PNP, yet these medicines have significant limitations, including limited efficacy, significant side effects, and carry the risk of addiction. We believe VX-548 holds potential for a superior overall benefit-risk profile in PNP and, given the large number of people with these conditions we believe that the U.S. PNP market represents another significant, multi-billion dollar opportunity.

In addition to these potential near-term commercial opportunities, we continue to advance our clinical-stage pipeline, which includes programs that have already achieved proof-of-concept, including programs in APOL1-mediated kidney disease (“AMKD”) and type 1 diabetes (“T1D”). In addition, VX-634 and VX-638 are being evaluated in Phase 1 clinical trials in Alpha-1 Antitrypsin Deficiency (“AATD”) and VX-670, a molecule in-licensed from Entrada Therapeutics (“Entrada”), is in Phase 1/2 development for myotonic dystrophy type 1 (“DM1”), an inherited disease affecting approximately 110,000 people in the U.S. and Europe that results in the weakening and destruction of skeletal muscles over time. Recently, we initiated a Phase 1 clinical trial of VX-407, which we are developing for autosomal dominant polycystic kidney disease (“ADPKD”), the most common genetic kidney disease, and representing our tenth disease area in the clinic.

From a financial perspective, our outstanding performance in 2023 resulted in net product revenues of $9.87 billion with strong operating margins and profitability. We are well-positioned to continue to create long-term value for both patients and shareholders with a portfolio of high-value medicines for CF, SCD and TDT, potential near-term commercial launches for products in acute pain and CF, a broad and deep pipeline across ten disease areas, clinical programs with multiple therapeutic modalities that range from small molecules to genetic and cell therapies, and an excellent financial profile.

Financial Performance

Our CF medicines, TRIKAFTA/KAFTRIO, SYMDEKO/SYMKEVI, ORKAMBI, and KALYDECO, are transforming the lives of eligible people around the globe and continue to drive our financial performance.

Our CF net product revenues increased to $9.87 billion in 2023, an increase of 11% or more than $900 million, from our 2022 CF net product revenues.
Our total R&D, acquired in-process research and development (“AIPR&D”) and selling, general and administrative (“SG&A”) expenses increased to $4.8 billion compared to $3.6 billion in 2022. This increase was primarily due to higher AIPR&D, increased investment in support of multiple programs that have advanced to mid- and late-stage clinical development, and the costs to support new launches of Vertex’s therapies globally.

Our differentiated R&D strategy has delivered not only a decade-long leadership position in CF, but also the historic, global approvals for CASGEVY, the first CRISPR-based gene-edited cell therapy to be approved in the world, for people with SCD or TDT.

In CF, advancingour goal is to bring highly effective treatments to all people with CF, and broadening our pipeline, increasing revenues and establishing a strong financial profile. We have two medicineswe began to do just that together arein January 2012 when KALYDECO was first approved to treat a CF population of approximately 25,000 patients1,000 people in the U.S. Since then, we have focused on growing the number of people eligible for our medicines, expanding access to our medicines in additional geographies, and seeking improved treatment options for all people with CF.

Today, our four approved CF medicines are collectively being used to treat nearly three quarters of the approximately 92,000 people with CF in North America, Europe, and Australia. Our CF medicines are used by people in over 60 countries and TRIKAFTA/KAFTRIO is now approved or approximately one thirdaccessible in more than 40 of these countries. In the near term, we expect our CF business to continue to grow as a result of (i) annualization of patients who recently initiated a CFTR modulator, (ii) label expansions, including into younger age groups and additional eligible mutations globally, (iii) expanded reimbursement, and (iv) the launch of the vanzacaftor triple, which will be a therapeutic option for those who have not yet initiated treatment with a CFTR modulator or who have discontinued from a CFTR modulator. In the mid- and longer-term, we foresee growth from (i) increases in the number of people living with CF, population worldwide. These(ii) VX-522, a potential new therapy for the treatment of the more than 5,000 people with CF who cannot benefit from CFTR modulators, and (iii) next-generation CFTR modulator regimens.

In SCD and TDT, 2023 marked the commercial launch of CASGEVY, following approvals in the U.S., U.K., and Bahrain, and with approvals in the E.U. and Saudi Arabia following closely in early 2024. We estimate approximately 35,000 people with severe SCD or TDT could be eligible for CASGEVY in the U.S. and Europe, with additional eligible people in Saudi Arabia and Bahrain. Our global launch strategy for CASGEVY is focused on disease education and awareness for patients, caregivers, health care professionals, payors, and policymakers, as well as engagement with the scientific and medical community regarding CASGEVY clinical data. Our strategy is also focused on activating authorized treatment centers to ensure their readiness to treat patients and achieving access for patients through reimbursement agreements with governments and commercial payors, as well as through early access programs where applicable.

Since the beginning of 2023, notable progress includes:

The U.S. Food and Drug Administration (“FDA”), the European Commission, the U.K. Medicines and Healthcare products Regulatory Agency (“MHRA”), and Health Canada approved TRIKAFTA/KAFTRIO for the treatment of children with CF 2 to 5 years of age who have at least one F508del mutation in the CFTR gene.
The FDA and the European Commission approved the use of ORKAMBI for children with CF from 12 months to less than 24 months of age who are homozygous for the F508del mutation.
The FDA approved KALYDECO in children with CF from 1 month to less than 4 months of age.
The approval of CASGEVY in the U.S., E.U., U.K., Saudi Arabia, and Bahrain for people 12 years of age and older with SCD or TDT.
We have engaged with the Medicaid administrators in all 50 U.S. states, focused on the 25 states with the highest prevalence of SCD patients, and have confirmed pathways to reimbursement in nearly all 25 of these priority states.
Approval by the French National Authority for Health of our request for the implementation of an early access program for the use of CASGEVY to treat eligible people with TDT from 12 to 35 years of age.
We have begun engagement with payors in the U.K., E.U., Saudi Arabia and Bahrain, including engagement with the National Institute for Health and Care Excellence.
Submission for approval of CASGEVY in both SCD and TDT in Switzerland.
Activation of 16 authorized treatment centers in the U.S., four authorized treatment centers in Europe, and one in Saudi Arabia.
Entry into an agreement with Synergie Medication Collective, a medication contracting organization, covering approximately 100 million people in the U.S., to provide access to CASGEVY.

Potential Near-Term Launch Opportunities

We are preparing for the following potential near-term launches of two new products:

Vanzacaftor triple in CF. We continued our strategy of serial innovation by completing three pivotal studies evaluating our once-daily triple combination CFTR modulator therapy, vanzacaftor/tezacaftor/deutivacaftor. Results of the clinical trials demonstrate that this triple combination has the potential to provide additional clinical benefits beyond TRIKAFTA for people with CF who have at least one mutation in their CFTR gene responsive to CFTR modulators. This regimen also has the advantages of once-daily dosing and a lower royalty burden compared with TRIKAFTA. We expect to support the launch of the vanzacaftor triple with our existing commercial infrastructure. We expect to submit global regulatory filings for this triple combination by mid-2024, including in the U.S., the E.U., and Canada for people with CF 6 years and older. In the U.S., we will be using one of our priority review vouchers to shorten the regulatory review period from ten months to six months.
VX-548 in acute pain. We completed three Phase 3 clinical trials for VX-548, a non-opioid, investigational selective NaV1.8 inhibitor, for the treatment of moderate-to-severe acute pain. Results of the clinical trials indicate that VX-548 could provide a transformative option for patients suffering from acute pain, based on the suboptimal benefit risk profile of existing agents, including the adverse effects and addictive potential of opioids, and the favorable benefit risk profile of VX-548. For our potential near-term commercial opportunity in acute pain, we are focused on the multi-billion dollar market arising from the estimated 80 million patients in the U.S. who are prescribed a medicine for their moderate-to-severe acute pain each year. More than two-thirds of patients receive acute pain prescriptions either during a hospital or ambulatory surgery center visit or at discharge; these prescriptions are concentrated in approximately 2,000 hospitals and 200 integrated delivery networks, which we believe we can reach with a specialty sales force. We plan to submit a New Drug Application (“NDA”) for the treatment of moderate-to-severe acute pain to the FDA by mid-2024.

Research and Development

We invest in research and development to discover and develop transformative medicines arefor people with serious diseases, with a focus on specialty markets. Our research and development strategy combines advances in the first,understanding of human disease and only,the science of therapeutics to dramatically advance human health. This strategy was designed to deliver transformative medicines that treatfor serious diseases at high rates of speed and success, and it has delivered just that. Our success in moving novel product candidates into clinical trials, successfully completing pivotal development and obtaining marketing approvals offer multiple proof points of this strategy, and include TRIKAFTA/KAFTRIO, SYMDEKO/SYMKEVI, ORKAMBI, and KALYDECO for CF, and CASGEVY for SCD and TDT. The strategy continues to be borne out by our pipeline, which includes potential future approvals of the underlying causevanzacaftor triple for the treatment of CF and we believe theyVX-548 for the treatment of acute pain. Our approach to drug discovery has also yielded therapies that have fundamentally changeddemonstrated clinical proof-of-concept in additional disease areas, including neuropathic pain with VX-548, AMKD with inaxaplin, and T1D with VX-880, a stem cell-derived islet cell therapy.

Our research and development approach also includes pursuing multiple modalities tailored to the way eligible patients can be treated.specific disease area target under investigation, using biomarkers that translate from the bench to the bedside, and advancing multiple candidates into clinical trials with the goal of bringing first-in-class, followed by best-in-class, therapies to patients. In addition to expanding our small molecule programs, we have a strong CF pipeline, withalso advanced an industry-leading portfolio of programs in cell and genetic therapies.

Our advancements across multiple drug candidates, that may allow us to help all patients with this raredisease areas and life-shortening disease.

Specifically, in 2015 we:
Increased the number of CF patients who are eligible for treatment with our medicines by approximately 700%:
modalities include:

Cystic Fibrosis. We continue to pursue next-in-class, small molecule CFTR modulator therapies and have already identified next-in-class correctors and potentiators, as well as genetic therapies for people with CF who do not make full-length CFTR protein and, as a result, cannot benefit from our current CF medicines. For these more than 5,000 people with CF, in collaboration with Moderna, we are developing VX-522, a CF mRNA therapeutic designed to treat the underlying cause of CF in these people by enabling cells in the lungs to produce functional CFTR protein. We have completed dosing in the single ascending dose portion of the clinical trial for VX-522 in people with CF and initiated the multiple ascending dose portion of the trial.
Obtained U.S.Sickle Cell Disease and E.U. approvalTransfusion-Dependent Beta Thalassemia. We completed enrollment in two global Phase 3 clinical trials evaluating CASGEVY in people 5 to 11 years of ORKAMBIage with SCD or TDT, and successfully launched ORKAMBI inwe are working on preclinical assets for gentler conditioning for CASGEVY, which could significantly broaden the U.S.
eligible patient population. In addition, we are investigating small molecules for the potential treatment of SCD and TDT.
ContinuedAcute Pain. We completed a Phase 1 clinical trial of an oral formulation of VX-993, our next-generation NaV1.8 inhibitor, and plan to increaseinitiate a Phase 2 study for the numbertreatment of patients eligible to receive KALYDECO through label expansions.
Advanced our CF development pipeline to help us reach our goal of developing treatments for all CF patients:
moderate-to-severe acute pain in 2024. We also anticipate initiating a Phase 1 study of an intravenous formulation of VX-993 in 2024.
ProgressedNeuropathic Pain. We announced positive Phase 32 clinical trial results for VX-548 in DPN, a common form of chronic PNP, and will be initiating pivotal clinical development of VX-661 in combination with ivacaftor, which may enhance treatment for patients currently eligible for ORKAMBI.
Initiated development of VX-152 and VX-440, next-generation correctors that could allow us to increase the benefits our medicines provide to CF patients and increase the number of CF patients eligible for our medicines.
In-licensed from Parion Sciences, Inc. VX-371, an investigational ENaC inhibitor, which provides us an approach that, if successful, could be used as a treatment for all CF patients regardless of their CFTR mutation.
Established a collaboration with CRISPR Therapeutics AG pursuant to which we are seeking to discover medicines aimed at the underlying genetic causes of human diseases, including CF, using CRISPR-Cas9 gene editing technology.

APOL-1 Mediated Kidney Disease. We completed enrollment in the Phase 2B dose-ranging portion of the clinical trial evaluating inaxaplin for the treatment of AMKD and have selected the dose for and initiated the Phase 3 portion of the Phase 2/3 pivotal clinical trial.
Type 1 Diabetes. We completed Parts A and B, and completed enrollment in Part C of the Phase 1/2 clinical trial evaluating VX-880, an allogeneic, stem-cell derived, fully-differentiated, insulin-producing islet cell therapy, used in conjunction with standard immunosuppression, for the treatment of T1D in people with impaired awareness of hypoglycemia and recurrent hypoglycemic events. We have placed the study on a protocol-specified pause, pending review of the totality of the data by the independent data monitoring committee. The clinical trial for our second program in T1D, VX-264, in which the allogeneic stem-cell derived, fully-differentiated, insulin-producing islet cells are encapsulated and implanted in an immunoprotective device to obviate the need for immunosuppression, is a multi-part Phase 1/2 study. We have completed enrollment and dosing in Part A, and Part B of the clinical trial is underway in multiple centers and countries.
Myotonic dystrophy type 1. We are exploring multiple approaches to address the underlying causal biology for DM1, including an oligonucleotide linked to a circular peptide, VX-670, which was in-licensed from Entrada. The Investigational New Drug Application (“IND”) for the Phase 1/2 clinical trial of VX-670 in people with DM1 has cleared, as have the regulatory submissions in Canada, the U.K. and multiple other geographies. The study has been initiated in Canada and is expected to initiate in other regions in the near term.
Alpha-1 Antitrypsin Deficiency. We continue to enroll and dose Phase 1 clinical trials evaluating VX-634 and VX-668.
Autosomal Dominant Polycystic Kidney Disease. We completed pre-clinical enabling studies for VX-407, our first-in-class small molecule corrector that targets the underlying cause of ADPKD in people with a subset of PKD1 genetic variations, in late 2023. The IND for VX-407 in the U.S. has cleared and we have initiated a Phase 1 clinical trial evaluating VX-407 in healthy volunteers in the U.S.
In addition to the programs listed above, we have several earlier-stage research programs aimed at diseases that fit our R&D strategy, as well as follow-on programs in diseases already in the clinic.

We will continue investing in our research and development programs and fostering scientific innovation by identifying additional product candidates through our internal research efforts and investing in business development transactions to access emerging technologies, products and product candidates.

SUMMARY INFORMATION (continued)



2023 Compensation Decisions and Shareholder Engagement
We have adopted significant changes toPay-for Performance

In 2023, our executive compensation program and in particular, toreceived substantial support, with approval by approximately 89% of the equity compensation component, which were implemented in early 2016. The new equity compensation reflects fundamental changes in our business and financial profile and feedback we received from our shareholders. While we continually engage in dialoguevotes cast at the annual meeting. We believe this support is consistent with our shareholders, we increased our level of engagement in response to the decline in support for our advisory say-on-pay proposal at our 2015 annual meeting. Over the past year, we held specific discussions regarding executive compensation with shareholders representing approximately 75% of our outstanding stock.

Similar to other development-stage companies and consistent with market practices, our long-term equity grants historically have been weighted toward granting equity awards at levels based on absolute numbers of shares, which we refer to as a share-based approach. Over the last several years, the value of annual compensation reported in the Summary Compensation Tables for our named executive officers has increased due primarily to our share-based approach, the strong performanceshareholders’ understanding of our business model and increases in our share price. During this period,the long-term value we also matured from a development-stage company to a commercial-stage global biotechnology company with a strong financial profile and a clear path to sustainable revenues and earnings growth. In early 2016, consistent with market practices for companies at our stage of development we transitioned from a share-based approach to a value-based approach for our long-term equity program.
Adoption of New "Value-Based" Equity Compensation Program
In response to the feedback we received during our shareholder engagement efforts, we adopted a new approach for 2016 for granting equity and equity-based compensation to our executives, including our named executive officers. Under this program (which we sometimes refer to herein as our "value-based" program), awards of equity compensation are no longer based upon a targeted number of shares. The value-based program provides that:
Annual awards to our executives will be sized based upon a target grant-date value, which will be determined based upon a holistic analysis of market data, business needs and other considerations that thecreating. Our management development and compensation committee or MDCC, deems relevant;
The targeted values are expected to result in grants with significantly fewer shares on an annual basis than the prior, share-based approach;
The awards themselves will be comprised of a mix of award types,(“MDCC”) and a majority of the value of each award will have performance features (e.g., performance vesting or stock option awards); and
The size of annual equity awards also takes into consideration individual performance results as well as adherence to corporate values, including our uncompromising commitment to patients and focus on innovation.
Under the value-based program, our CEO will be eligible for annual equity awards with a value between zero and $14 million (with the actual value depending upon his performance), as compared to a grant date fair-value of $23.3 million in 2015 under the prior share-based approach. Our other named executive officers will be eligible for annual equity awards with values between zero and $4.5 million, as compared to the grant date fair-values for such officers in 2015, which ranged from $6.6 million to $7.5 million.
In reviewing the compensation information included in this proxy statement, it is important to note that the equity compensation in these tables for 2015 reflects compensation received under the program we had in place prior to the changes implemented in early 2016.

SUMMARY INFORMATION (continued)

Shareholder Feedback and Response
The following chart summarizes what we heard from shareholders and how we responded in our revised equity compensation program.
CONCERNS WE HEARDWHAT WE DID
Magnitude of awards resulting from our share-based equity programChanged to a value-based equity program which should reduce grant date fair-value of our CEO's equity awards by 40% in 2016
Exclusive use of time-based equityImplemented performance-contingent restricted stock unit awards, significantly reducing our reliance on time-based stock option awards
Rigor of vesting terms for one-time retention awards granted in 2014Implemented balanced financial and non-financial metrics with a substantial risk of forfeiture for performance-contingent restricted stock unit awards
Dilution created by compensation programChanged to value-based program which should significantly reduce dilution; for example, the number of shares at target subject to CEO equity awards will decrease by approximately 44% in 2016

A detailed discussion and analysis of our executive compensation begins on page 46 of this proxy statement. Consistent with the changes we made to our executive compensation program, we also have implemented changes to our non-employee director compensation program to shift to a value-based program that will result in a more than 50% decrease in non-employee director equity compensation in 2016 as compared to 2015.
Proxy Access and Shareholder Engagement
Throughout 2015, we continued discussions with a number of our shareholders regarding, among other matters, our corporate governance practices. During these discussions we listened to our shareholders' perspectives and gained insight into how we could further align the interests of our company with the interests of our shareholders. In April 2016, we implemented a proxy access by-law. This amendment to our by-laws was in response to the approval of a proxy access shareholder proposal at our 2015 annual meeting. Our shareholder engagement regarding proxy access included discussions over the last several months with a number of our largest shareholders that together hold approximately 46% of our outstanding stock. This engagement allowed us to gain valuable feedback as to the particular proxy access parameters that our shareholders consider appropriate. Based on that feedback and after considering various proxy access provisions recently adopted by other companies, including peers such as Alexion and pharmaceutical companies such as Pfizer, our board of directors adoptedreviewed our compensation programs and made the following key decisions with respect to 2023 compensation:

We maintained the base salary and target equity level for Dr. Reshma Kewalramani, our CEO and President, based on a comparative analysis of companies in our peer group, and maintained her target cash bonus as a percentage of base salary.
We maintained target compensation for Mr. Stuart Arbuckle, Dr. David Altshuler, and Mr. Charles Wagner, based on a comparative analysis of companies in our peer group.
Dr. Leiden continues to receive no cash compensation for his role as Executive Chairman other than an annual cash payment intended to facilitate participation in the company’s benefit plans, and he will continue to receive equity awards for his fifth year of service as Executive Chairman.
Our outstanding performance in 2023 resulted in the board determining that we had achieved a leading rating for 2023 (150 out of a potential 150), with the payment of annual cash bonuses commensurate with this high level of performance.
We maintained the mix of equity granted to our NEOs with 50% of the awards consisting of performance stock units (“PSUs”) that vest upon achievement of specific performance goals and 50% consisting of time-vesting restricted stock units (“RSUs”). This mix rewards stock price appreciation and incentivizes long-term tenure.

Shareholder Engagement

We believe that a proxy access frameworkrobust 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.

During 2023, we solicited feedback regarding our corporate governance practices from our top 40 shareholders representing approximately 65% of our outstanding shares. Our integrated outreach team included leaders from our Investor Relations, Human Resources, Corporate Responsibility, Corporate Communications, and Legal teams, and we discussed numerous topics of shareholder interest, including our business strategy, R&D approach, diversity initiatives and metrics, employee engagement and development, corporate governance, political and lobbying disclosures, executive compensation, and environmental sustainability matters.

WHAT IS A PROXY?
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. We have designated Jeffrey M. Leiden, Ian F. Smith, Michael Parini and Michael J. LaCascia to serve as proxies at the annual meeting.
WHAT IS A PROXY STATEMENT?
It is a document that provides certain information about a company and matters to be voted upon at a meeting of shareholders. The SEC and other applicable law require us to give you, as a shareholder, the information in this proxy statement and certain other information when we are soliciting your vote.
WHAT IS THE DIFFERENCE BETWEEN A SHAREHOLDER OF RECORD AND A SHAREHOLDER WHO HOLDS STOCK IN STREET NAME?
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 these proxy materials were sent directly to you by Computershare.
Street Name Holders. If you hold your shares in an account at a bank or broker, then you are the beneficial owner of shares held in “street name.” The proxy materials were forwarded to you by your bank or broker, who is considered the shareholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your bank or broker how to vote the shares held in your account.
HOW MANY SHARES MUST BE REPRESENTED IN ORDER TO HOLD THE ANNUAL MEETING?
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. If you are a shareholder of record, your shares are counted as present if you properly return a proxy card or voting instruction form by mail or if you attend the annual meeting and vote in person. 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. 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.
HOW CAN I VOTE AT THE ANNUAL MEETING IF I OWN SHARES IN STREET NAME?
If you are a street name holder, you may not vote your shares at the annual meeting unless you obtain a legal proxy from your bank or broker. A legal proxy is a bank’s or broker’s authorization for you to vote the shares it holds in its name on your behalf.
WHAT IS THE RECORD DATE AND WHAT DOES IT MEAN?
The record date for the annual meeting is April 20, 2016 and was established by our board of directors. On the record date, there were 247,349,864 shares of our common stock entitled to vote. Owners of record of common stock at the close of business on the record date are entitled to:

Shareholders may revoke a proxy and/or change their vote prior to the completion of voting at the annual meeting by:
signing another proxy card with a later date and delivering it to our Secretary, Michael J. LaCascia, 50 Northern Avenue, Boston, Massachusetts 02210, before the annual meeting; or
voting at the annual meeting, if you are a shareholder of record or hold your shares in street name and have obtained a legal proxy from your bank or broker.
WHAT IF I DO NOT SPECIFY A CHOICE FOR A MATTER WHEN RETURNING A PROXY?
Shareholders should specify their choice for each matter following the directions described on their proxy card. If no specific instructions are given, proxies that are signed and returned will be voted:

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 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 and the four shareholder proposals are not considered 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.

This amendment was in response to the approval of a shareholder proposal at our 2015 annual meeting. Our engagement with our shareholders regarding proxy access included discussions over the last several months with a number of our largest shareholders that together hold approximately 46% of our outstanding stock. This engagement allowed us to gain valuable feedback as to the particular proxy access parameters that our shareholders consider appropriate. Based on that feedback and after considering various proxy access provisions recently adopted by other companies, including biotech peers such as Alexion and pharmaceutical companies such as Pfizer, our board of directors adopted a proxy access framework that it believes will provide meaningful access for shareholders while safeguarding the interest of all our shareholders and limiting the potential for abuse.

CORPORATE GOVERNANCE AND RISK MANAGEMENT

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.”

INDEPENDENCE, CHAIR AND CO-LEAD INDEPENDENT DIRECTORS

Director Independence

Our board of directors has determined that eightnine of our nine directorseleven director nominees qualify as “independent” under the definition of that term adopted by The Nasdaq Stock Market LLC or Nasdaq. These(“Nasdaq”). In addition, Mr. Kearney, one of our current directors who is not standing for re-election at our 2024 annual meeting of shareholders, was determined to be an independent director. Our independent director nominees are Dr. Bhatia, Mr. Carney, Dr. Boger,Garber, Mr. Kearney, Mr. Lee,Lagarde, Ms. McGlynn,McKenzie, Mr. Sachs, Dr. Schneider, Ms. UllianThornberry, and Mr. Young. Dr. Wayne Riley was an independent director prior to his resignation from our board in June 2015.Upadhyay. Our independent directors generally meet in executive session without management at each regularly scheduled board meeting.

Dr. Leiden, our president and chief executive officer, serves as the chairman of our board. Our employment agreement with Dr. Leiden provides that he will serve as the chairman of our board through December 31, 2017. In addition, we have two co-lead independent directors who are elected by the independent directors. Each of the board committees is chaired bycomposed 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.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) 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.

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.

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, and ourgovernance. Our corporate governance principlesguidelines require that if the chairChair is not an independent director, that the independent directors shall elect a lead independent director.Lead Independent Director. Since December 2011, Mr. Sachs and Ms. Ullian havehas served as our co-leadLead 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 directors. 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.

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 monitoring of, and controls over, 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 Technology Committee

Our sciencereviews of significant transactions. Longer term risks are addressed by the board through the annual strategic planning process, during which the board discusses and technology committee dischargesreviews our board’s responsibilitieslong-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.

Such outside advisors and experts are retained on a regular basis to assist the board and its committees in evaluating, managing, and anticipating risks, and include external auditors, legal counsel, compensation consultants, and business consultants, as appropriate.

We are a member of select industry and trade groups that are generally aligned with our business objectives and political contribution philosophy. These organizations represent the biotechnology industry and/or businesses more broadly in engaging with policy makers on issues that affect our industry. The industry and trade organizations to which Vertex paid more than $25,000 in dues have been disclosed on our website. Our governmental affairs executives regularly evaluate our participation in these organizations to ensure that they continue to be aligned with our contribution criteria and principles. We do not direct, nor do we have discretion over, how our membership dues are used and do not always agree with positions taken by these organizations and/or their members.

At times, we may contribute to certain 501(c)(4) organizations that engage in lobbying or political activity. We will disclose such organizations annually on our website, and, to the extent available to us, the portion of those payments used for activities that are not deductible under Chapter 162(e) of the Internal Revenue Code. We do not contribute funds intended for elections to 501(c)(4) organizations.

We recognize that increasingly, investors are asking public companies to provide additional visibility regarding their political engagement and contributions and to provide information about accountability and oversight. We have made available on our website our political engagement principles, which provide transparency on our approach to political contributions, including lobbying activities. We have shared this with shareholders, engaged in productive dialogues on this topic, and update this information annually.

CORPORATE RESPONSIBILITY

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 2023. A selection of awards and recognitions include Fortune 100 Best Companies to Work For® 2023, Forbes’ Best Employers for Diversity, PEOPLE® Magazine’s 100 Companies That Care, Points of Light’s Civic 50, Science Magazine’s Top Employers, Seramount’s 100 Best Companies, and many others.

Our corporate responsibility priorities relate to four objectives fundamental to our business: improving the lives of people with serious diseases, fostering a culture of innovation, integrity, and inclusion; carefully managing our operations and environmental footprint; and making a positive impact in the communities where we are located.

Improve the Lives of People with Serious Diseases

We are relentless in our pursuit to create transformative medicines for people with serious diseases. This has been our singular purpose for more than 30 years. We involve the voices of people living with the diseases early in our drug discovery and development processes. We listen, learn and incorporate the patient voice in our decisions and our R&D, every step of the way.

Our unique approach to building drug discovery programs has led to the development of four medicines that treat the underlying cause of CF, and the first-ever approved CRISPR-based gene edited cell therapy for SCD and TDT. At the end of 2023, our CF medicines were reimbursed or accessible to patients in more than 60 countries. In the U.S., more than 99 percent of eligible patients have access to TRIKAFTA through public and private insurance. We also have initiated a pilot program in lower-income countries to provide our latest triple combination therapy at no cost to eligible people with CF. In the geographies where CASGEVY is approved, we are actively working with key commercial and government payers and policymakers with the goal of securing rapid access for eligible patients with SCD and TDT.

We recognize the importance of going beyond R&D to engage in advocacy, awareness, and community support and are deeply committed to understanding the challenges and unmet needs of patients. We support programs and initiatives designed to raise disease awareness, educate health care professionals, strengthen R&D, and provide support to nonprofit organizations and patients. In 2023, we sponsored numerous programs and initiatives, including the Cystic Fibrosis Research Institute’s (“CFRI”) National CF Education Conference, the Rock CF Foundation’s Boltcast program, the Sickle Cell Community Consortium’s Warriors Convention and Caregiving Summit, the SCD Partnership, and the American Kidney Fund’s APOL1 Education Campaign.

Foster a Culture of Innovation, Integrity, and Inclusion

Our success depends on nurturing a culture and team that values innovation, integrity and inclusion. Our culture of high ethical standards and integrity is one of the key components to our success, and each employee is responsible for upholding and demonstrating ethics and integrity in our work every day. Our Code of Conduct, anonymous compliance hotline, and robust investigation process are in place to help ensure that we are adhering to the highest standards of ethics and accountability.

We believe that each employee brings unique perspectives and strengths, and by embracing these strengths, we can do our best work for patients. We focus on recruiting, retaining, and developing employees from a diverse range of backgrounds and view diversity through a broad lens that encompasses culture, backgrounds, experiences, and worldview to foster creativity and innovation.

Seven of our eleven director nominees are women and/or from underrepresented ethnic and racial groups. As of December 31, 2023, women represented 55% of our global workforce.

Carefully Managing Our Operations and Environmental Footprint

We are committed to limiting our environmental impacts and to operating our business in a sustainable manner. We make strong local efforts to reduce our impact on the environment.

From 2022 to 2023, we reduced absolute GHG emissions by 3.5%. Building on this achievement, in 2023 we established a new target to reduce our Scope 1 and Scope 2 GHG emissions by 42% by 2032 from a 2022 baseline. 49% of our global energy comes from renewable energy sources and we continue to source 100% renewable electricity for our U.K.-based international headquarters and R&D facility. We also have ongoing efforts to minimize waste across all of our sites through employee engagement initiatives, vendor takeback programs and improved product distribution processes. Many of our facilities around the world are highly efficient, sustainable buildings. In 2023 our Jeffrey Leiden Center for Cell and Genetic Therapies was certified LEED (Leadership in Energy and Design) Platinum, the highest level of LEED certification for sustainable interior design and construction. Based on our efforts, we received a score of A- on the 2023 CDP Climate Change survey, demonstrating environmental leadership and a higher score than the global average of C.

We strive to offer our employees, contractors and visitors a healthy and safe work environment and continually seek ways to improve our practices. For example, each of our research and manufacturing sites has a Safety Committee, a forum where safety representatives, safety officers and Environmental, Health and Safety personnel meet regularly to discuss health and safety at the site and recommend preventive and corrective actions. We continually improve our performance by investing in safety programs and incorporating industry best practices to ensure that employees, contractors and visitors experience a healthy and safe work environment.

We also focus on the safety and security of our supply chain to protect our products and patients. Our medicines meet the highest safety, ethical and environmental standards and our teams work to prevent, detect and respond to instances of product diversion, tampering and counterfeiting, and to maintain the quality of our products for the patients who rely on them.

ENGAGEMENT
Making a Positive Impact in the Communities Where We are Located

We are committed to making a positive difference in the communities where we are located. Our progress and efforts in corporate responsibility, community engagement, and workplace practices were recognized broadly in 2023. A selection of awards and recognitions include PEOPLE Magazine’s 100 Companies That Care, Points of Light’s Civic 50, and many others.

We support our communities through collaborations, donations, and volunteering across the world. In 2023, Vertex and the Vertex Foundation contributed more than $42 million in charitable giving. The Vertex Foundation, a 501(c)(3) nonprofit organization, seeks to improve the lives of people with serious diseases and contribute to our communities through education, innovation and health. In 2023, the Vertex Foundation provided grants in support of STEAM education, healthy families, and social innovation, with a focus on projects and organizations demonstrating a strong commitment to inclusion, diversity, and equity.

Our corporate giving extends and expands our long-term commitment to patients with serious diseases and our communities, with an on-going focus on STEAM education. For example, in 2023, we offered opportunities to nearly 3,000 students through our Learning Lab programs in Boston, San Diego, and Oxford, U.K., and, through the Vertex Foundation, provided 86 scholarships to people with CF and their family members who are pursuing higher education. The Vertex Foundation is also committed to supporting programs and initiatives designed to nurture the next generation of innovators, enable innovative solutions to community challenges, and support the quality of life of families with members living with serious diseases.

Volunteering and giving back are core to our culture. Throughout the year, we encourage our employees to participate in community service through the Vertex Volunteers program, including activities such as pro bono service conducted by members of our legal and compliance group and our 15th annual Day of Service. Last year, 60% of Vertex employees around the globe volunteered during Day of Service, contributing more than 8,200 volunteer hours to their local communities. Additionally, in 2023, we supported nearly 2,200 nonprofit organizations through the Vertex Foundation Matching Gift Program, which matches employee donations 1:1 to thousands of eligible nonprofit organizations.

PROPOSAL NO. 2:   RATIFICATION OF ERNSTTHE  APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Engagement of Ernst & YOUNGYoung LLP

Our audit and finance 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, 20162024 is in the best interest of our company and our shareholders.

In determining whether to reappoint our independent registered public accounting firm, our audit and finance committee undertakes an annual formal evaluation of the independent registered public accounting firm, during which it 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.

Each year, our audit and finance committee, together with Ian F. Smith, our executive vice president and chief financial officer, and Paul Silva, our senior vice president and controller, review the selection of our lead audit partner from Ernst & Young LLP. The review considers several factors, including sound judgment, industry knowledge and experience managing audits of complex companies with substantial international operations. After undertaking such review, we decided to retain the same lead audit partner from Ernst & Young LLP for the 2016 audit. In accordance with applicable requirements, we are required to change our lead audit partner everevery 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.

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 and finance committee requires that we obtain its specific pre-approval for these services.

The audit and finance 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 and finance committee at its next scheduled meeting.

All of the services set forth above in the categories “audit-related fees,” “tax fees”fees,” and “all other fees” were pre-approved and none were approved by our audit and finance committee pursuant to Rule 2-01(c)(7)(i)(C), of Regulation S-X, which relates to the approval of a de minimisamount of non-audit services after the fact but before completion of the audit.

ITEM 3 - ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

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

Our compensation program is structureddesigned to attract, retain, and motivate talented and experienced leaders and reward our executive officers for the achievementindividuals across all areas of short- and long-term strategic and operational goals while avoiding inappropriate or excessive risk-taking. In 2015, our board of directors and the MDCC decided, based on fundamental changes in our business and financial profile and feedback we received from our shareholders, to adopt significant changes to our executive compensation program, and in particular, our equity compensation program that were implemented in early 2016.

As described in the Summary Information beginning on page 3 of this proxy statement and Compensation Discussion and Analysis section beginning on page 38 of this proxy statement, based on fundamental changes in our business and financial profile and feedback we received from our shareholders, we adopted significant changes to our executive compensation program, and in particular, our equity compensation program that were implemented in early 2016.
Our compensation for our named executive officers was supported by 45% of the “Say-on-Pay” advisory votes cast by our shareholders in 2015. In 2015, we continued discussions with our shareholders regarding, among other matters, our executive compensation program and dilution caused by our broad-based equity compensation program. During these discussions, which included discussions with shareholders representing approximately 75% of our common stock, we listened to their perspectives and gained insight into how we could further align the interests of our companyemployees, 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 2023, our annual advisory vote on executive compensation received support from approximately 89% of the votes cast at the annual meeting of shareholders. Based in part onWe believe this feedback,support is consistent with our shareholders’ understanding of our business model and the long-term value we made significant changesare creating. We plan to continue a high level of shareholder engagement regarding our equityexecutive compensation program, which we believe will allow usprogram.

Our focus is and continues to (i)be maintaining the strong link between our compensation programs and our ability to continue to attract, retain and motivatedevelop transformative medicines while delivering sustained company performance, with 90% of our named executive officers and (ii) address the concerns raised by our shareholders. As a result of these changes, our named executive officer's total equityNEO compensation as provided in the summary compensation tables is expectedlinked to decrease by 40% to 45% in 2016 under the new program as compared to our NEO's total equity compensation in 2015 under the prior program.

performance. Our board of directors and MDCC reviewedroutinely review our compensation programs and made the following key decisions:
In early 2016, we implemented significant changesdecisions with respect to our equity compensation program (i.e., the adoption of the value-based program).
For 2015, adjusted base salaries to align our named executive officers' salaries closer to median levels.
As a result of our exceptional performance in 2015, our board approved annual cash bonuses at the high-end of the range for each of our named executive officers.
2023 compensation:

We maintained the base salary, target cash bonus, and target equity level for Dr. Kewalramani, based on a comparative analysis of companies in our peer group.
Based on a comparative analysis of companies in our peer group, we maintained target compensation for Dr. Altshuler, Mr. Arbuckle and Mr. Wagner.
Under Dr. Leiden’s amended employment agreement, he receives no cash compensation for his Executive Chairman role other than an annual cash payment intended to facilitate participation in the company’s benefit plans. Dr. Leiden will receive equity awards for his fifth year in his Executive Chairman role.
Our outstanding performance in 2023 resulted in the board determining that we had achieved a leading rating for 2023 (150 out of a potential 150), with the payment of annual cash bonuses commensurate with this high level of performance.
We maintained the mix of equity granted to our NEOs with 50% of the awards consisting of performance stock units that vest over time but only upon achievement of specific performance goals and 50% consisting of time-vesting restricted stock units. This mix rewards stock price appreciation and incentivizes long-term tenure.

Our executive compensation program, including our performance and the compensation earned byof our named executive officers,NEOs, is discussed in greater detail in the Compensation Discussion and Analysissection beginning on page 3850 of this proxy statement. In

As required by Section 14(a) of the Exchange Act, our board of directors is asking that section, we discuss our executive compensation program and policies and explain the compensation decisions relating to our named executive officers for 2015. In addition, the compensation tables and related narratives, which begin on page 67 of this proxy statement, provide additional information regarding the compensation received by our named executive officers in 2015. In reviewing the compensation information included in this proxy statement, it is important to note that the equity compensation in these tables for 2015 reflects compensation received under the program we had in place prior to the changes implemented in early 2016.

Based uponshareholders cast a vote of shareholders at the 2011 annual meeting of shareholders, following our Board’s recommendation for an annualnon-binding, advisory vote to approve executive compensation, we are presentingFOR the following proposal, which gives you as a shareholder the opportunity to endorse or not endorse our 2015 executive compensation program by voting for or against the following resolution:

Supporting Statement

Proposal 4 — Special Shareholder Meeting Improvement

 

Shareholders ask our board to take the steps necessary to amend the appropriate company governing documents to give the owners of a combined 10% of our outstanding common stock the power to call a special shareholder meeting.

To make up for our complete lack of a right to act by written consent we need the right of 10% of shares to call for a special shareholder meeting. Hundreds of major companies provide shareholders with the following resolution:

RESOLVED,right to act by written consent.

Certain companies, that shareholdersdo not provide for a shareholder right to act by written consent, have a more reasonable stock ownership threshold to call for a special shareholder meeting. Southwest Airlines is an example of a company that does not provide for shareholder written consent and yet provides for 10% of shares to call for a special shareholder meeting.

Since a special shareholder meeting can be useful in replacing a director, this proposal may be an incentive for the Vertex Pharmaceuticals urgedirectors to improve their performance and in turn improve the stock price.

Calling a special shareholder meeting is hardly ever used by shareholders but the main point of the right to call a special shareholder meeting is that it gives shareholders a Plan B option if management is not interested in good faith shareholder engagement. An incentive for management to engage with shareholders in good faith could be the alternative of a special shareholder meeting.

With the widespread use of online shareholder meetings it is much easier for management to conduct a special shareholder meeting and our bylaws thus need to be updated accordingly.

To anticipate a fake management objection to this proposal, shareholders who own 5% to 10% of a company are often the least likely shareholders to call for a special shareholder meeting.

Please vote yes:

Special Shareholder Meeting Improvement — Proposal 4

VERTEX PHARMACEUTICALS INCORPORATED - 2024 Proxy Statement     45

Board of Directors to take all necessary steps (other than any steps that must be taken by shareholders) to eliminate the classification of the Board of Directors and to require that all directors elected at or after the annual meeting held in 2016 be elected on an annual basis. Implementation ofDirectors’ Statement In Opposition

The board has carefully considered this proposal shouldand, for the reasons described below, has found it not prevent any director elected prior to the annual meeting held in 2016 from completing the term for which such director was elected.

SUPPORTING STATEMENT
The resolution urges the board of directors to facilitate a declassification of the board. Such a change would enable shareholders to register their views on the performance of all directors at each annual meeting. Having directors stand for elections annually makes directors more accountable to shareholders, and could thereby contribute to improving performance and increasing firm value.
Director accountability is of particular importance at Vertex Pharmaceuticals where the Company's advisory vote on executive compensation received the support of only 45% of votes cast at the 2015 annual shareholder meeting.
The significant shareholder support for declassification proposals is consistent with empirical studies reporting that:
Classified boards are associated with lower firm valuation (Bebchuk and Cohen, 2005; confirmed by Faleye (2007) and Frakes (2007));
Takeover targets with classified boards are associated with lower gains to shareholders (Bebchuk, Coates, and Subramanian, 2002);
Firms with classified boards are more likely to be associated with value-decreasing acquisition decisions (Masulis, Wang, and Xie, 2007); and
Classified boards are associated with lower sensitivity of compensation to performance and lower sensitivity of CEO turnover to firm performance (Faleye, 2007).
Although one study (Bates, Becher and Lemmon, 2008) reports that classified boards are associated with higher takeover premiums, this study also reports that classified boards are associated with a lower likelihood of an acquisition and that classified boards are associated with lower firm valuation.
Please vote for this proposal to make directors more accountable to shareholders.
VERTEX'S STATEMENT IN OPPOSITION TO SHAREHOLDER PROPOSAL NO. 1
Our board of directors recommends a vote AGAINST the shareholder proposal requesting that we take necessary steps to declassify our board.
Our board does not believe that declassifying our board is in the best interest of the company or its shareholders and recommends that you vote AGAINST Proposal 4.

A 10% threshold may harm Vertex’s shareholders

As shown in the “Security Ownership of Certain Beneficial Owners and Management” table beginning on page 89, four of our shareholders separately own 5% or more of Vertex’s outstanding common stock. Lowering the threshold required to call a special shareholder meeting to 10% would provide two of such shareholders acting together to call a shareholder meeting. The board believes such a low threshold creates the risk that two shareholders may use this procedure to act unilaterally, or even threaten to do so to pressure the company, advancing their own special interests at the expense of other shareholders. The board further notes that adopting a 10% threshold would put the company in the minority of S&P 500 companies, as only approximately 12% of S&P companies have adopted a threshold of 10% or less.

The current ownership threshold appropriately balances the interests of all shareholders

Our board recognizes the importance of having strong corporate governance practices in place to ensure that the company is responsive to shareholder concerns. Our board further believes that shareholders should have a meaningful right to call special meetings in appropriate circumstances. As such, the company’s current by-laws allow shareholders who own 40% or more of the company’s outstanding common stock to call a special meeting. The by-laws allow shareholders to raise important matters with the company and demonstrates our commitment to effective corporate governance. Importantly, a 40% threshold provides a level of assurance that a reasonable number of shareholders consider a matter important enough to warrant a special meeting. Reducing the threshold to 10%, as proposed, could cause the company to spend significant resources on special meetings even if holders of up to 90% of the company’s shares do not believe that the issue warrants a special meeting.

If the shareholder proposal were adopted, a small minority of large shareholders—possibly even two shareholders as noted above— could force the company to devote outsized attention and resources to the special interests of that minority, at the expense of the company’s smaller shareholders. Maintaining our current threshold protects our smaller shareholders from the potentially narrow, short-term interests of a 10% shareholder, or a few shareholders totaling 10%. Lowering the threshold to 10% would allow such shareholders to call an unlimited number of special meetings, without regard to how direct costs and other burdens might affect the company’s future success or the interests of the vast majority of shareholders.

Special meetings require substantial company resources and time

Preparing for, and holding, a special meeting is time-consuming and expensive. In connection with conducting a special meeting, the following reasons:

Independence, Stability, Continuitycompany must pay to prepare, print, and Experience
Ourdistribute disclosure documents to shareholders, solicit proxies, hold the meeting, and tabulate votes, among other things—even if the meeting is held online. Moreover, holding a special meeting at the request of such a small minority of shareholders has the potential to injure the company, as special meetings demand significant attention from the board of directors is divided into three classes, with each class serving a staggered three-year term. The longer term enhances the independence of our board and encourages the directors to make decisions in the long-term interest of our companysenior management and our shareholders, reducing the potential influence of certain investors and special interest groups with short-term agendas that may be harmful to our company and shareholders in the long-term. The classified board structure also

creates stability and continuity on our board and ensures that, at any given time, our board is comprised of experienced directors who are intimately familiar with ourdisrupt normal business strategic goals, history and culture.
Protects Shareholder Value
The classified board structure protects our company and our shareholders against a hostile purchaser replacing a majority of our directors with its own nominees at a single annual meeting of shareholders, thereby gaining control of our company without paying fair market value to our shareholders. A classified board does not preclude a takeover, but rather provides our board with the time and flexibility necessary to evaluate the adequacy and fairness of a proposed offer, consider alternative methods of maximizing shareholder value, protect shareholders against abusive tactics during a takeover process, and, as appropriate, negotiate the best possible return for all shareholders.
Accountability
All directors, regardless of the length of their term, have a fiduciary duty under the law to act in a manner that they believe to be in the best interests of our company and all of our shareholders.operations. As a result, the classified board structure maintains the same level of accountability as with annual elections of directors. In addition, we have adopted a majority vote standard for the election of directorsbelieve special meetings should be limited to when there are urgent and require that any nominee for director in an uncontested election who receives a greater number of votes “withheld” than votes “for” the nominee’s election shall promptly tender hisimportant strategic matters or her resignation to the chair of our board following certificationprofound fiduciary concerns. Our existing threshold helps avoid waste of the company’s and shareholder vote for consideration byresources on addressing narrow or special interests.

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

The board further believes that Vertex’s strong corporate governance practices make adoption of this proposal unnecessary. Our corporate governance practices provide the appropriate means to advance shareholder interests without the potential expense and risk of abuse that would come with lowering the threshold to call a special meeting. For example, our corporate governance and nominating committee.

practices 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.
Independent Board and Committee Leadership.Our board is led by a Lead Independent Director and each of our board Committees are chaired by, and composed solely of, independent directors.
Shareholder Engagement.We have an ongoing, year-round shareholder engagement program and management regularly meets with shareholders who submit matters of concern or interest to our attention.
Majority Vote Standard.Our by-laws provide for the election of directors by a majority votes cast in uncontested elections.
Proxy Access.Our by-laws provide for proxy access which permits shareholders, or a group of 20 shareholders, owning 3% or more of our outstanding shares of common stock continuously for at least three years to nominate and include in our proxy materials nominees for director constituting up to 20% of the Board or two directors, whichever is greater, subject to the requirements set for in our by-laws.
Majority Vote for Charter and By-Law Amendments.Our charter and by-law provisions do not have supermajority voting provisions - shareholders can approve binding charter and by-law amendments with a majority vote.

For all of the above reasons, our board of directors unanimously recommends that you vote AGAINST this shareholder proposal.

Arjuna Capital, 13 Elm Street, Manchester, Massachusetts 01944, representing its clients, John Silva and Shana Weiss through the Silva-Weiss Living Trust, which is the owner of 9,215at least $25,000 worth of shares of our common stock as of December 22, 2015,6, 2023, has given notice that it intendsthey intend to present for action at the 2016our 2024 annual meeting of shareholders the following resolution:

RESOLVED:

Whereas: Pay inequities persist across race and gender and pose substantial risks to companies and society. Black workers’ median annual earnings represent 77 percent of white wages. The shareholders askmedian income for women working full time is 84 percent that of men. Intersecting race, Black women earn 76 percent and Latina women 63 percent.1 At the boardcurrent rate, women will not reach pay equity until 2059, Black women in 2130, and Latina women in 2224.2

Citigroup estimates closing minority and gender wage gaps 20 years ago could have generated 12 trillion dollars in additional national income. PwC estimates closing the gender pay gap could boost Organization for Economic Cooperation and Development (OECD) countries’ economies by 2 trillion dollars annually.3

Actively managing pay equity is associated with improved representation. Diversity in leadership is linked to superior stock performance and return on equity.4 Minorities represent 40 percent of directorsVertex’s workforce and 22 percent of executives. Women represent 54 percent of the workforce and 33 percent of executives.5

Best practice pay equity reporting consists of two parts:

1.unadjusted median pay gaps, assessing equal opportunity to high paying roles,
2.statistically adjusted gaps, assessing whether minorities and non-minorities, men and women, are paid the same for similar roles.

Vertex Pharmaceuticals Incorporated to adopt a policy that in the event of a change in control (as defined under any applicable employment agreement, equity inventive plandoes not report quantitative unadjusted or other plan), there shall be no acceleration of vesting of any equity award granted to any senior executive officer, provided, however, that the board's Compensation Committee may provide in an applicable grant or purchase agreement that any unvested award will vest on a partial, pro rata basis up to the timeadjusted pay gaps. About 50 percent of the senior executive officer's termination, with such qualifications for100 largest U.S. employers currently report adjusted gaps, and an awardincreasing number of companies disclose unadjusted gaps to address the structural bias women and minorities face regarding job opportunity and pay.6

Racial and gender unadjusted median pay gaps are accepted as the valid way of measuring pay inequity by the United States Census Bureau, Department of Labor, OECD, and International Labor Organization. The United Kingdom and Ireland mandate disclosure of median gender pay gaps.7 For its United Kingdom employees, Vertex reports a median hourly pay gap of 20 percent and bonus gender pay gap of 26 percent.8

Resolved: Shareholders request Vertex Pharmaceuticals report on both quantitative median and adjusted pay gaps across race and gender, including associated policy, reputational, competitive, and operational risks, and risks related to recruiting and retaining diverse talent. The report should be prepared at reasonable cost, omitting proprietary information, litigation strategy and legal compliance information.

Racial/gender pay gaps are defined as the Committee may determine.

For purposesdifference between non-minority and minority/male and female median earnings expressed as a percentage of this Policy, "equity award" means an award granted under annon-minority/male earnings (Wikipedia/OECD, respectively).

Supporting Statement: An annual report adequate for investors to assess performance could, with board discretion, integrate base, bonus and equity incentive plan as defined in item 402 of the SEC's Regulation S-K, which addresses elements of executive compensation to be disclosed to shareholders.

VERTEX PHARMACEUTICALS INCORPORATED - 2024 Proxy Statement     47

Board of Directors’ Statement In Opposition

The board has carefully considered this proposal is adopted, and, for the reasons described below, has found it shall apply only to equity awards made under equity incentive plans or plan amendments that shareholders approve after the date of the 2016 annual meeting.

SUPPORTING STATEMENT
Vertex Pharmaceuticals Incorporated ("Company") allows senior executives to receive an accelerated award of unearned equity under certain conditions after a change of control of the Company. We do not question that some form of severance payments may be appropriate in that situation. We are concerned, however, that current practices at the Company may permit windfall awards that have nothing to do with an executive's performance.
According to last year's proxy statement, a change of control and an involuntary termination other than for cause or a termination by the executive for good reason could have accelerated the vesting of more than $133 million worth of long-term equity to Company's five senior executives, with the Chairman, President and CEO Jeffrey M. Leiden entitled to more than $57 million.
We are unpersuaded by the argument that executives somehow "deserve" to receive unvested awards. To accelerate the vesting of unearned equity on the theory that an executive was denied the opportunity to earn those shares seems inconsistent with a "pay for performance" philosophy worthy of the name.
We do believe, however, that an affected executive should be eligible to receive an accelerated vesting of equity awards on a pro rata basis as of his or her termination date, with the details of any pro rata award to be determined by the Compensation Committee.
Other major corporations, including Apple, Chevron, ExxonMobil, IBM, Intel, Microsoft, and Occidental Petroleum, have limitations on accelerated vesting of unearned equity, such as providing pro rata awards or simply forfeiting unearned awards. Research from James Reda & Associates found that over one third of the largest 200 companies now pro rate, forfeit, or only partially vest performance shares upon a change of control.
We urge you to vote FOR this proposal.
VERTEX'S STATEMENT IN OPPOSITION TO SHAREHOLDER PROPOSAL NO. 2
Our board of directors recommends a vote AGAINST the shareholder proposal requesting that we adopt a policy limiting acceleration of equity awards to senior executives upon a change of control.
We believe that it is in the best interest of ourthe company or its shareholders and recommends that you vote AGAINST Proposal 5.

Vertex is making a new commitment to retain the current provisions regarding acceleration of equity awards in the event of a change of control as set forth in employment agreements with our senior executive officersdisclose adjusted gender and the terms of the individual equity awards. These provisions do not provide for automatic acceleration in the event of a change of

ITEM 5 - SHAREHOLDER PROPOSAL NO. 2 (continued)

control, but instead require a "double trigger" consisting of both a change of control and the involuntary termination of a senior executive officer within a specified time following such change in control.
We believe that our management development and compensation committee, or MDCC, which is composed entirely of independent directors, is in the best position to design and implement executive compensation arrangements that are appropriate for our company, including the treatment of equity awards in connection with a change in control. The proposal would preemptively tie the hands of the MDCC with respect to a significant element of our executive compensation program and would place our company at a competitive disadvantage in attracting and retaining highly qualified and talented executives relative to competing companies, many of whom have acceleration provisions that are similaraccountability to our existing provisions.
We also believe the current policy appropriately aligns the interests of senior executivesinvestors and other stakeholders. In addition to our annual report on Inclusion, Diversity, and Equity at Vertex and our shareholders. In the eventannual disclosure of a potential change of control, the retentive power ofEEO-1 demographic data, we believe additional disclosure regarding our existing compensation programpay practices would be diminished if senior executives were to forfeit a portion of their equity awards,beneficial. Accordingly, and the potential loss of key executives could mitigate the ability of the company to deliver an intact management team and achieve critical performance goals. Such an outcome could reduce the value of the company to an acquirer and thereby negatively affect the amount shareholders would realize in the change of control transaction. In addition, our existing compensation program helps mitigate against the potential misalignment of interests between our senior executives and our shareholders in the event of a change of control transaction by ensuring that our senior executives, who would otherwise forfeit a significant portion of their equity compensation if they are terminated in connection with a change of control, remain objective, avoid conflicts of interest and stay focused on executing a transaction that maximizes shareholder value.
The current treatment of equity grants following a change in control is consistent with our overarching goals of providing pay for performance and attracting and retaining highly talented executives in a competitive marketplace where similar provisions are common. Our board does not believe the proposal would be in the best interest of shareholders.
FOR ALL OF THE ABOVE REASONS OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE AGAINST THE APPROVAL OF SHAREHOLDER PROPOSAL NO. 2. THE AFFIRMATIVE VOTE BY THE HOLDERS OF A MAJORITY OF THE VOTES CAST IN PERSON OR BY PROXY ON THIS MATTER IS REQUIRED FOR THE APPROVAL OF THIS PROPOSAL.

ITEM 6 - SHAREHOLDER PROPOSAL NO. 3

We expect the following shareholder proposal will be presented for consideration at the 2016 annual meeting of shareholders. Our board of directors recommends a vote AGAINST the shareholder proposal for the reasons set forth following the proposal.
SHAREHOLDER PROPOSAL AND SUPPORTING STATEMENT
Proposal
The Comerica Bank & Trust, National Association, Institutional Services Group, MC 3464, PO Box 75000, Detroit, Michigan 48275, as trustee of the Trowel Trades S&P 500 Index Fund, an owner of 3,990 shares of our common stock as of December 23, 2015 and the International Brotherhood of Electrical Workers Pension Benefit Fund, 900 Seventh Street, NW, Washington, DC 20001, an owner of 3,441 shares of our common stock as of December 24, 2015, have given notice that they, or one of them, intend to present for action at the 2016 annual meeting of shareholders the following resolution:

RESOLVED: Shareholders of Vertex Pharmaceuticals Incorporated (the "Company") urge the Compensation Committee of the Board of Directors (the "Committee") to adopt a policy requiring that senior executives retain a significant percentage of shares acquired through equity compensation programs until reaching normal retirement age or terminating employment with the Company. For the purpose of this policy, normal retirement age shall be defined by the Company's qualified retirement plan that has the largest number of plan participants. The shareholders recommend that the Committee adopt a share retention percentage requirement of at least 50 percent of net after-tax shares. The policy should prohibit hedging transactions for shares subject to this policy which are not sales but reduce the risk of loss to the executive. This policy shall supplement any other share ownership requirements that have been established for senior executives, and should be implemented so as not to violate the Company's existing contractual obligations or the terms of any compensation or benefit plan currently in effect.
SUPPORTING STATEMENT
Equity-based compensation is an important component of senior executive compensation at our Company. While we encourage the use of equity-based compensation for senior executives, we are concerned that our Company's senior executives are generally free to sell shares received from our Company's equity compensation plans. In our opinion, the Company's current share ownership guidelines for its senior executives do not go far enough to ensure that the Company's equity compensation plans continue to build stock ownership by senior executives over the long-term.
For example, our Company's share ownership guidelines require the CEO to hold an amount of shares equivalent to six times his base salary or 150,000 shares. In comparison, the CEO currently owns 778,728 shares. Additionally, in 2015, our Company granted the CEO 509,000 stock and option awards. In other words, one year's worth of equity awards exceeds by three times the Company's long-term share ownership guidelines for the CEO.
We believe that requiring senior executives to only hold shares equal to a set target loses effectiveness over time. After satisfying these target holding requirements, senior executives are free to sell all the additional shares they receive in equity compensation.
Our proposal seeks to better link executive compensation with long-term performance by requiring a meaningful share retention ratio for shares received by senior executives from the Company's equity compensation plans. Requiring senior executives to hold a significant percentage of shares obtained through equity compensation plans until they reach retirement age will better align the interests of executives with the interests of shareholders and the Company. A 2009 report by the Conference Board Task Force on Executive Compensation observed that such hold-through-retirement requirements give executives "an ever growing incentive to focus on long-term stock price performance as the equity subject to the policy increase" (available at http://www.conference-board.org/pdf_free/ExecCompensation2009.pdf).
We urge shareholders to vote FOR this proposal.
VERTEX'S STATEMENT IN OPPOSITION TO SHAREHOLDER PROPOSAL NO. 3
Our board of directors recommends a vote AGAINST the shareholder proposal requesting that we adopt a policy requiring that senior executives retain a percentage of their equity awards.

Notice of Annual Meeting of Shareholders and 2016 Proxy Statement | 34

ITEM 6 - SHAREHOLDER PROPOSAL NO. 3 (continued)

Our board has already taken steps to align the interests of our senior executives with those of shareholders and to encourage a focus on the long-term performance of our company. These steps, which render the proponents proposal unnecessary, include the following:
Executive Stock Ownership Guidelines: We already have stock ownership guidelines for our senior executive officers. These guidelines provide that our chief executive officer should, within five years of becoming subject to the guidelines, satisfy at least one of the following two criteria: (i) ownership of shares of our common stock with a value at least six times his then-current base salary or (ii) ownership of at least 150,000 shares of our common stock. Our executive vice presidents should, within five years of becoming subject to these guidelines, achieve ownership of shares of our common stock with a value at least four times such executive vice president’s then-current base salary.
Clawback Policy: We have a clawback policy providing that, if our board 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 reimbursement for 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.
Anti-Hedging Policy: We prohibit all of our directors and employees worldwide, including our executive officers, from (i) short selling or hedging our securities, (ii) purchasing or selling derivative securities based on our securities and (iii) pledging our securities.
These policies and practices have been carefully designed to align the interests of executive officers with those of our shareholders and encourage a focus on the long-term performance of our company, while enabling us to attract and retain talented executives. We believe that the approach set forth in the proposal fails to strike a reasonable balance between incenting desired management behaviors and permitting executives to manage their own financial affairs. The proposal would place unnecessary constraints on executives’ legitimate needs to diversify their holdings and could hinder our ability to attract and retain executive talent.
FOR ALL OF THE ABOVE REASONS OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE AGAINST THE APPROVAL OF SHAREHOLDER PROPOSAL NO. 3. THE AFFIRMATIVE VOTE BY THE HOLDERS OF A MAJORITY OF THE VOTES CAST IN PERSON OR BY PROXY ON THIS MATTER IS REQUIRED FOR THE APPROVAL OF THIS PROPOSAL.

ITEM 7 - SHAREHOLDER PROPOSAL NO. 4

We expect the following shareholder proposal will be presented for consideration at the 2016 annual meeting of shareholders. Our board of directors recommends a vote AGAINST the shareholder proposal for the reasons set forth following the proposal.
SHAREHOLDER PROPOSAL AND SUPPORTING STATEMENT
Proposal
The Gun Denhart Living Trust, an owner of our common stock with a market value of at least $2,000, has given notice that it intends to present for action at the 2016 annual meeting of the shareholders the following resolution:
WHEREAS: A large and diverse group of companies has integrated sustainability metrics into executive pay incentive plans, among them Walt Disney, Unilever, Pepsi, Walmart, Group Danone and Mead Johnson.
Numerous studies suggest companies that integrate environmental, social and governance factors into their business strategy reduce reputational, legal and regulatory risks and improve long-term performance.
According to the largest study of CEOs on sustainability to date (CEO Study on Sustainability 2013, UN Global Compact and Accenture):
76 percent believe embedding sustainability into core business will drive revenue growth and new opportunities.
93 percent regard sustainability as key to success.
86 percent believe sustainability should be integrated into compensation discussions, and 67 percent report they already do.
A 2012 Harvard Business School study concluded that firms that adopted social and environmental policies significantly outperformed counterparts over the long-term, in terms of stock market and accounting performance.
The Glass Lewis report Greening the Green 2014: Linking Executive Pay to Sustainability, finds a "mounting body of research showing that firms that operate in a more responsible manner may perform better financially.... Moreover, these companies were also more likely to tie top executive incentives to sustainability metrics."
A 2012 report by the United Nations Principles for Responsible Investment and the UN Global Compact found "the inclusion of appropriate Environmental, Social and Governance (ESG) issues within executive management goals and inventive schemes can be an important factor in the creation and protection of long-term shareholder value."
In 2013, CH2MHill found that firms that set tangible sustainability goals are more likely to tie executive compensation to the achievement of sustainability goals.
Vertex shareholders have expressed their dissatisfaction with pay practices at the company. At the company's last annual meeting, only 45% of shareholders approved the advisory vote on compensation. This was the third lowest vote of all S&P 500 companies. A focus on sustainability will be an improvement.
SUPPORTING STATEMENT
Effectively managing for sustainability creates opportunities for long-term value creation, we therefore believe sustainability should be a key area in which executives are evaluated.
Linking sustainability metrics to executive compensation could reduce risks related to sustainability underperformance and incent executives to meet sustainability goals and achieve resultant benefits. Examples of such metrics might include: greenhouse gas emissions monitoring and reduction goals, green procurement programs, energy consumption (including renewable energy sourcing and efficiency), and progress toward workforce diversity goals.
RESOLVED: Shareholders request the Board Compensation Committee prepare a report assessing the feasibility of integrating sustainability metrics into the performance measures of senior executives under Vertex Pharmaceuticals' compensation incentive plans. Sustainability is defined as how environmental and social considerations, and related financial impacts, are integrated into corporate strategy over the long term.




Notice of Annual Meeting of Shareholders and 2016 Proxy Statement | 36

SHAREHOLDER PROPOSAL NO. 4 (continued)

VERTEX'S STATEMENT IN OPPOSITION TO SHAREHOLDER PROPOSAL NO. 4
Our board of directors recommends a vote AGAINST the shareholder proposal requesting a report assessing the feasibility of integrating sustainability into performance measures for senior executive compensation.
We believe that our MDCC, which is composed entirely of independent directors, is in the best position to design and implement executive compensation arrangements that are appropriate for our company, including the performance metrics for senior executives under our equity compensation plans. To that end, the MDCC needs flexibility to develop effective and competitive compensation programs and to establish short- and long-term performance metrics for individual equity awards. While it may be appropriate from time to time to incorporate new performance measures into our executive compensation program, the MDCC is in the best position to evaluate whether such additions will promote our goals and create long-term shareholder value.
Although our board agrees that sustainability is important, we believe that our existing executive compensation program, as modified for 2016, has a strong pay-for-performance philosophy that results in awards to executives that are responsive to the long-term value they produce for shareholders and our underlying mission of discovering, developing, manufacturing and commercializing medicines for serious diseases.
Nonetheless, we are committed to conserving natural resources and minimizing or eliminating any adverse health, safety and environmental impacts that may be associated with our facilities and operations and to promoting waste minimization, recycling and energy efficiency in our business activities. For example, and as a direct resultfurtherance of our commitment to sustainability,pay equity, we recently achieved LEED Gold certificationswill conduct an adjusted pay gap analysis of our workforce with respect to gender and race using 2024 data and will provide quantitative disclosure regarding the results of this analysis in 2025. We also commit to conducting and disclosing this analysis on an annual basis.

Reporting median pay gaps on an unadjusted basis, as requested in the proposal, would not provide any meaningful supplemental information, and can be misleading

Although the proposal is aimed at providing transparency with respect to pay equity, the unadjusted median pay ratio it requests is not a statistic that demonstrates whether women and employees belonging to underrepresented racial and ethnic groups are being paid fairly at Vertex for highthe roles they perform. This is because unadjusted median pay ratios merely compare the compensation midpoint for different groups of employees without adjusting for relevant factors that can explain variances in compensation. For instance, unadjusted median pay ratios do not account for factors such as job function, job level, education, experience, tenure, market pricing, labor force participation rates, performance, and geography, all of which legitimately impact compensation.

The board believes that an adjusted pay ratio, which takes into account such factors, provides a more accurate picture of pay equity and that our shareholders would not benefit from a broad, surrogate measurement of pay equity that would not provide any meaningful, additional information to help our shareholders evaluate the impact, effectiveness and equity of our pay practices.

We are committed to compensating employees fairly and equitably and believe that all employees should receive equal pay for equal work, regardless of gender, race, ethnicity, or any other protected traits

At Vertex, our success is driven by the quality of our people, whom we believe are among the best and brightest in sustainable site development, water savings, energy efficiency, materials selectionthe life sciences industry. Our continued success depends on the collective strengths of our employees, and indoor environmental quality.

we are dedicated to attracting, retaining, and rewarding the performance of our diverse workforce to best advance our mission to develop transformative medicines for people with serious diseases. We do not discriminate on the basis of race, ethnicity, gender, gender identity, sexual orientation, age, religion, national origin, veteran status, disability, pregnancy, or any other basis prohibited by law and we strive to retain talented employees from all backgrounds, to support employee success and well-being, and to foster a culture of innovation. We have established a commitment to fair and competitive pay practices for our employees and undertake many initiatives to ensure employees are paid equitably.

Our policies and practices reflect our commitment to pay equity

Vertex has adopted policies in support of our commitment to equal employment opportunity and fair treatment of employees. Our policies and practices with respect to pay equity include:

Policies designed to compensate employees in accordance with their job and level, without regard to gender, race, or other protected categories.
Collection and review of external market and benchmark pay data along with internal pay data on an annual basis by job. Twice a year, during our mid- and year-end performance and compensation cycles, we analyze performance rating and pay decision distributions across groups to flag outliers and any other instances for further review. We conduct pay equity analyses using a variety of statistical methods to ensure that our pay practices are equitable at the group and individual levels.
Computation of adjusted pay gaps across demographic groups, testing for differences in means and the shape of the distributions by demographic characteristics. In some small populations where there might be differences, we validate that they are explained by legitimate, nondiscriminatory, job-related factors such as function, experience, and tenure. At the individual employee level, we use multiple regression models to again validate that demographic variables do not influence compensation.
Supplementing our internal analyses by engaging third-party experts (e.g., legal and compensation advisory firms), who conduct independent pay equity reviews that include advanced statistical analyses and for smaller populations where statistical analysis is not as useful, the third-party expert conducts cohort reviews to understand whether inequities exist. The analysis controls for a variety of legitimate, nondiscriminatory, job-related factors, including location, job family, job level, job performance, and relevant skills and experience. If we find an area of opportunity, we address it to ensure that employees are paid equitably for the same work.

VERTEX PHARMACEUTICALS INCORPORATED - 2024 Proxy Statement     48

Our longstanding commitment to gender and racial equality is embedded in our culture, which embraces inclusion, diversity, and equity

In our pursuit of scientific breakthroughs, we believe that good ideas come from people of all backgrounds. We are the most innovative, make the best decisions for patients and recruit the best talent when we have an inclusive, diverse and equitable workforce and culture. We value inclusion, diversity, and equity (“ID&E”) not only because it is the right thing to do, but also because it drives our business success.

We currently disclose gender and racial representation in our ID&E Fact Sheet, which also describes many of the programs we have to foster a culture that embraces ID&E. For example, our employee resource networks (“ERNs”) are voluntary, employee-led groups open to all employees that amplify the voices of our colleagues from traditionally underrepresented groups. These groups foster community and connection through education, leadership, development, networking, and volunteering, while also encouraging the kind of open dialogue that leads to stronger allyship across Vertex. Our employee resource networks first launched in 2016 and, since that time, membership has grown tremendously, from just over 100 members in a few locations to over 2,200 members across the globe in groups like IWILL, VIBE, PRIDE and BRAVE.

Our commitment to building and supporting ID&E in our workplace has been recognized by several leading organizations. These include a score of 100 on Human Rights Campaign’s Corporate Equality Index, and recognition on lists such as Fortune 100 Best Companies to Work For® 2023, Forbes Best Employers for Diversity, Seramount 100 Best Companies, STEM Workforce Diversity Top 50 Employers, People’s 100 Companies That Care, Newsweek America’s Most Responsible Companies, Science Magazine Top Employers, San Diego Business Journal Best Places to Work, and Boston Business Journal Best Places to Work.

As a result of our existing policies and procedures, as well as our new commitment to disclose adjusted pay gaps in 2025, the board believes that the adoption of this proposal — which includes an unadjusted pay gap component — is unnecessary and not in the best interests of our company or our shareholders.

FOR ALL OF THE ABOVE REASONS OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE For all of the above reasons, our board of directors unanimously recommends that you vote AGAINST THE APPROVAL OF SHAREHOLDER PROPOSAL NO. 4.

The Management Development and Compensation Committee’s stewardship of Vertex’s compensation programs is guided by Vertex’s mission of developing transformative medicines for people with serious diseases.diseases and, by so doing, creating value for our shareholders. Toward that end, 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. ThisWe believe that this alignment has contributed to Vertex ’s exceptional performanceVertex’s remarkable accomplishments over the last several yearsdecade as it has significantly increased the number of patients benefiting from Vertex builtmedicines each year, established a strong financial position with significant growth in revenues, continued delivery of strong operating margins and cash flows, and accelerated the advancement of its leadership positionpipeline of small molecule drug candidates and cutting edge cell and genetic therapies, all in accordance with its core strategy of investing in scientific innovation to create transformative medicines for people with serious diseases, with a focus on specialty markets. These accomplishments have been recognized by the company’s shareholders and have been reflected in the treatmentincreasing value that the company’s shareholders have attributed to the company. Vertex’s market capitalization has increased from approximately $7 billion in early 2012 to approximately $105 billion at the end of cystic fibrosis (CF), advanced its pipeline and increased its CF net product revenues. This performance has helped the company build outstanding financial strength and deliver total shareholder returns of 200% for the three years ended December 31, 2015.

2023.

We take seriously our role in the governance of compensation programs including how these programs should evolve asand the company transforms from a development-stage organization to a profitable commercial enterprise. We also carefully considerimportance of recruiting, motivating, and incorporate the views expressed by the company’s shareholders into our thinking. Based on the progressionretaining highly capable and critical executive talent. The success of the company and input from shareholders, we transitioned Vertex’s equity program from a share-based program (that provided for annual equity grants based on specific numbers of shares) to a value-based approach (that provides for annual equity grants based on specific dollar values). As part of this transition, we made modifications to the equity program consistent with market practices for companies at Vertex’s stage of development, including decreasing our reliance on options and implementing performance stock units (which utilize a balance of financial and non-financial goals tied to the execution of Vertex’s business strategy over the company's strategic objectives)last several years has depended upon the leadership, stability and operational excellence of our senior executive team.

2023 was a landmark year for Vertex as the company continued to successfully execute its business strategy. The research and development team made significant progress in advancing multiple programs, including those designed to treat cystic fibrosis (“CF”), sickle cell disease (“SCD”), transfusion-dependent beta thalassemia (“TDT”), acute and neuropathic pain, APOL1-mediated kidney disease, type 1 diabetes, myotonic dystrophy type 1, alpha-1 antitrypsin deficiency, and autosomal dominant polycystic kidney disease. More recently, in 2024, the company announced positive results from the Phase 3 clinical trials of its triple combination of vanzacaftor/tezacaftor/deutivacaftor (the “vanzacaftor triple”), which holds the potential to deliver even greater benefits to people with CF than TRIKAFTA, as well as from the Phase 3 clinical trials of VX-548 for the treatment of moderate-to-severe acute pain. With these advancements, Vertex’s research and development strategy is continuing to deliver a broad and deep pipeline of potentially transformative therapies, and thereby providing the opportunity for meaningful value for patients and shareholders.

2023 also marked an important pivot point for the company, as it commercially diversified into new disease areas with the historic regulatory approvals for CASGEVY, the first CRISPR gene-edited cell therapy to be approved in the world, as a potential one-time functional cure for people with SCD or TDT. Vertex also continued to expand its long-term leadership in CF by reaching younger age groups and additional geographies with existing medicines. With the recent data from the vanzacaftor triple and VX-548, Vertex is well-positioned to maintain its leadership in CF and further strengthendiversify commercially into the link between paypain market.

The company delivered outstanding financial performance in 2023, achieving CF net product revenues of $9.87 billion, an 11% increase compared to 2022, representing over a decade of consecutive years of double-digit growth. This revenue growth drove significant growth in earnings, and performance.the company finished the year in a strong financial position with $13.7 billion in total cash, cash equivalents, and marketable securities. The senior management team additionally strengthened the company’s organizational capabilities by recruiting and onboarding top-tier talent across the organization and filling critical hires with superior and diverse talent.

The company’s comprehensive success in 2023 reflects the execution of our differentiated corporate strategy championed by our senior management team. Consistent with these outstanding results, for 2023, our executives received above-target cash bonuses and payouts on performance stock unit awards based both on one-year business and financial goals. We believe that many of the enhancementsthese outcomes are aligned with our commitment to the company’s equity program, which we implemented in February 2016, are consistent with the feedback from the company’s shareholders, and we plandirectly link pay to continue to engage in an active dialogue with these important constituents.

COMPENSATION DISCUSSION AND ANALYSIS - OVERVIEW (continued)

Executive Summary

This section discusses the principles underlying our policies and decisions with respect to the compensation of our "named executive officers"NEOs for 2023 and all materialthe factors we believe are relevant to an analysis of these policies and decisions. Our namedNEOs for 2023 are listed below.

Financial Performance

Our CF medicines, TRIKAFTA/KAFTRIO, SYMDEKO/SYMKEVI, ORKAMBI, and KALYDECO, are transforming the lives of eligible people around the globe and continue to drive our financial performance.

Our CF net product revenues increased to $9.87 billion in 2023, an increase of 11% or more than $900 million, from our 2022 CF net product revenues.
Our total R&D, AIPR&D and SG&A expenses increased to $4.8 billion compared to $3.6 billion in 2022. This increase was primarily due to higher AIPR&D, increased investment in support of multiple programs that have advanced to mid- and late-stage clinical development, and the costs to support new launches of Vertex’s therapies globally.

Marketed Products

Our differentiated R&D strategy has delivered not only a decade-long leadership position in CF, but also the historic, global approvals for CASGEVY, the first CRISPR-based gene-edited cell therapy to be approved in the world, for people with SCD or TDT.

In CF, our goal is to bring highly effective treatments to all people with CF, and we began to do just that in January 2012 when KALYDECO was first approved to treat a CF population of approximately 1,000 people in the U.S. Since then, we have focused on growing the number of people eligible for our medicines, expanding access to our medicines in additional geographies, and seeking improved treatment options for all people with CF.

Today, our four approved CF medicines are collectively being used to treat nearly three quarters of the approximately 92,000 people with CF in North America, Europe, and Australia. Our CF medicines are used by people in over 60 countries and TRIKAFTA/KAFTRIO is now approved or accessible in more than 40 of these countries. In the near term, we expect our CF business to continue to grow as a result of (i) annualization of patients who recently initiated a CFTR modulator, (ii) label expansions, including into younger age groups and additional eligible mutations globally, (iii) expanded reimbursement, and (iv) the launch of the vanzacaftor triple, which will be a therapeutic option for those who have not yet initiated treatment with a CFTR modulator or who have discontinued from a CFTR modulator. In the mid- and longer-term, we foresee growth from (i) increases in the number of people living with CF, (ii) VX-522, a potential new therapy for the treatment of the more than 5,000 people with CF who cannot benefit from CFTR modulators, and (iii) next-generation CFTR modulator regimens.

In SCD and TDT, 2023 marked the commercial launch of CASGEVY, following approvals in the U.S., U.K., and Bahrain, and with approvals in the E.U. and Saudi Arabia following closely in early 2024. We estimate approximately 35,000 people with severe SCD or TDT could be eligible for CASGEVY in the U.S. and Europe, with additional eligible people in Saudi Arabia and Bahrain. Our global launch strategy for CASGEVY is focused on disease education and awareness for patients, caregivers, health care professionals, payors, and policymakers, as well as engagement with the scientific and medical community regarding CASGEVY clinical data. Our strategy is also focused on activating authorized treatment centers to ensure their readiness to treat patients and achieving access for patients through reimbursement agreements with governments and commercial payors, as well as through early access programs where applicable.

Since the beginning of 2023, notable progress includes:

The FDA, the European Commission, the MHRA, and Health Canada approved TRIKAFTA/KAFTRIO for the treatment of children with CF 2 to 5 years of age who have at least one F508del mutation in the CFTR gene.
The FDA and the European Commission approved the use of ORKAMBI for children with CF from 12 months to less than 24 months of age who are homozygous for the F508del mutation.
The FDA approved KALYDECO in children with CF from 1 month to less than 4 months of age.
The approval of CASGEVY in the U.S., E.U., U.K., Saudi Arabia, and Bahrain for people 12 years of age and older with SCD or TDT.
We have engaged with the Medicaid administrators in all 50 U.S. states, focused on the 25 states with the highest prevalence of SCD patients, and have confirmed pathways to reimbursement in nearly all 25 of these priority states.
Approval by the French National Authority for Health of our request for the implementation of an early access program for the use of CASGEVY to treat eligible people with TDT from 12 to 35 years of age.
We have begun engagement with payors in the U.K., E.U., Saudi Arabia and Bahrain, including engagement with the National Institute for Health and Care Excellence.
Submission for approval of CASGEVY in both SCD and TDT in Switzerland.
Activation of 16 authorized treatment centers in the U.S., four authorized treatment centers in Europe, and one in Saudi Arabia.
Entry into an agreement with Synergie Medication Collective, a medication contracting organization, covering approximately 100 million people in the U.S., to provide access to CASGEVY.

Potential Near-Term Launch Opportunities

We are preparing for the following potential near-term launches of two new products:

Vanzacaftor triple in CF. We continued our strategy of serial innovation by completing three pivotal studies evaluating our once-daily triple combination CFTR modulator therapy vanzacaftor/tezacaftor/deutivacaftor. Results of the clinical trials demonstrate that this triple combination has the potential to provide additional clinical benefits beyond TRIKAFTA for people with CF who have at least one mutation in their CFTR gene responsive to CFTR modulators. This regimen also has the advantages of once-daily dosing and a lower royalty burden compared with TRIKAFTA. We expect to support the launch of the vanzacaftor triple with our existing commercial infrastructure. We expect to submit global regulatory filings for this triple combination by mid-2024, including in the U.S., the E.U., and Canada for people with CF 6 years and older. In the U.S., we will be using one of our priority review vouchers to shorten the regulatory review period from ten months to six months.
VX-548 in acute pain. We completed three Phase 3 clinical trials for VX-548, a non-opioid, investigational selective NaV1.8 inhibitor, for the treatment of moderate-to-severe acute pain. Results of the clinical trials indicate that VX-548 could provide a transformative option for patients suffering from acute pain, based on the suboptimal benefit risk profile of existing agents, including the adverse effects and addictive potential of opioids, and the favorable benefit risk profile of VX-548. For our potential near-term commercial opportunity in acute pain, we are focused on the multi-billion dollar market arising from the estimated 80 million patients in the U.S. who are prescribed a medicine for their moderate-to-severe acute pain each year. More than two-thirds of patients receive acute pain prescriptions either during a hospital or ambulatory surgery center visit or at discharge; these prescriptions are concentrated in approximately 2,000 hospitals and 200 integrated delivery networks, which we believe we can reach with a specialty sales force. We plan to submit an NDA for the treatment of moderate-to-severe acute pain to the FDA by mid-2024.

Research and Development

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 combines advances in the understanding of human disease and the science of therapeutics to dramatically advance human health. This strategy was designed to deliver transformative medicines for serious diseases at high rates of speed and success, and it has delivered just that. Our success in moving novel product candidates into clinical trials, successfully completing pivotal development and obtaining marketing approvals offer multiple proof points of this strategy, and include TRIKAFTA/KAFTRIO, SYMDEKO/ SYMKEVI, ORKAMBI, and KALYDECO for CF, and CASGEVY for SCD and TDT. The strategy continues to be borne out by our pipeline, which includes potential future approvals of the vanzacaftor triple for the treatment of CF and VX-548 for the treatment of acute pain. Our approach to drug discovery has also yielded therapies that have demonstrated clinical proof-of-concept in additional disease areas, including neuropathic pain with VX-548, AMKD with inaxaplin, and T1D with VX-880, a stem cell-derived islet cell therapy.

Our research and development approach also includes pursuing multiple modalities tailored to the specific disease area target under investigation, using biomarkers that translate from the bench to the bedside, and advancing multiple candidates into clinical trials with the goal of bringing first-in-class, followed by best-in-class, therapies to patients. In addition to expanding our small molecule programs, we have also advanced an industry-leading portfolio of programs in cell and genetic therapies.

Our advancements across multiple disease areas and modalities include:

Cystic Fibrosis. We continue to pursue next-in-class, small molecule CFTR modulator therapies and have already identified next-in-class correctors and potentiators, as well as genetic therapies for people with CF who do not make full-length CFTR protein and, as a result, cannot benefit from our current CF medicines. For these more than 5,000 people with CF, in collaboration with Moderna, we are developing VX-522, a CF mRNA therapeutic designed to treat the underlying cause of CF in these people by enabling cells in the lungs to produce functional CFTR protein. We have completed dosing in the single ascending dose portion of the clinical trial for VX-522 in people with CF and initiated the multiple ascending dose portion of the trial.
Sickle Cell Disease and Transfusion-Dependent Beta Thalassemia. We completed enrollment in two global Phase 3 clinical trials evaluating CASGEVY in people 5 to 11 years of age with SCD or TDT, and we are working on preclinical assets for gentler conditioning for CASGEVY, which could significantly broaden the eligible patient population. In addition, we are investigating small molecules for the potential treatment of SCD and TDT.
Acute Pain. We completed a Phase 1 clinical trial of an oral formulation of VX-993, our next-generation NaV1.8 inhibitor, and plan to initiate a Phase 2 study for the treatment of moderate-to-severe acute pain in 2024. We also anticipate initiating a Phase 1 study of an intravenous formulation of VX-993 in 2024.
Neuropathic Pain. We announced positive Phase 2 clinical trial results for VX-548 in DPN, a common form of chronic PNP, and will be initiating pivotal clinical development this year. We also initiated a Phase 2 clinical trial of VX-548 in lumbosacral radiculopathy, another type of PNP. In addition, we expect to initiate a Phase 2 clinical trial evaluating an oral formulation of VX-993 for the treatment of PNP in 2024.
APOL-1 Mediated Kidney Disease. We completed enrollment in the Phase 2B dose-ranging portion of the clinical trial evaluating inaxaplin for the treatment of AMKD and have selected the dose for and initiated the Phase 3 portion of the Phase 2/3 pivotal clinical trial.

VERTEX PHARMACEUTICALS INCORPORATED - 2024 Proxy Statement     53

Type 1 Diabetes. We completed Parts A and B, and completed enrollment in Part C of the Phase 1/2 clinical trial evaluating VX-880, an allogeneic, stem-cell derived, fully-differentiated, insulin-producing islet cell therapy, used in conjunction with standard immunosuppression, for the treatment of T1D in people with impaired awareness of hypoglycemia and recurrent hypoglycemic events. We have placed the study on a protocol-specified pause, pending review of the totality of the data by the independent data monitoring committee. The clinical trial for our second program in T1D, VX-264, in which the allogeneic stem-cell derived, fully-differentiated, insulin-producing islet cells are encapsulated and implanted in an immunoprotective device to obviate the need for immunosuppression, is a multi-part Phase 1/2 study. We have completed enrollment and dosing in Part A, and Part B of the clinical trial is underway in multiple centers and countries.
Myotonic dystrophy type 1. We are exploring multiple approaches to address the underlying causal biology for DM1, including an oligonucleotide linked to a circular peptide, VX-670, which was in-licensed from Entrada. The IND for the Phase 1/2 clinical trial of VX-670 in people with DM1 has cleared, as have the regulatory submissions in Canada, the U.K. and multiple other geographies. The study has been initiated in Canada and is expected to initiate in other regions in the near term.
Alpha-1 Antitrypsin Deficiency. We continue to enroll and dose Phase 1 clinical trials evaluating VX-634 and VX-668.
Autosomal Dominant Polycystic Kidney Disease. We completed pre-clinical enabling studies for VX-407, our first-in-class small molecule corrector that targets the underlying cause of ADPKD in people with a subset of PKD1 genetic variants, in late 2023. The IND for VX-407 in the U.S. has cleared and we have initiated a Phase 1 clinical trial evaluating VX-407 in healthy volunteers in the U.S.
In addition to the programs listed above, we have several earlier-stage research programs aimed at diseases that fit our R&D strategy, as well as follow-on programs in diseases already in the clinic.

We will continue investing in our research and development programs and fostering scientific innovation by identifying additional product candidates through our internal research efforts and investing in business development transactions to access emerging technologies, products and product candidates.

The following chart represents our clinical stage programs and select pre-clinical programs.

Increasing Shareholder Value

Driven by our financial performance and pipeline successes, our stock price increased 40.9% from $288.78 per share at the end of 2022 to $406.89 per share at the end of 2023. We believe biotechnology companies are best measured over the long term, as opposed to one-year or other shorter-term increments. The following charts show our total shareholder return relative to the NBI and S&P 500 index since the beginning of 2012, when our first CF medicine was approved, as well as our stock price performance over multiple periods. We believe the execution of our differentiated research and development approach and corporate strategy will continue to create shareholder value over the long term.

2023 Compensation Decisions and Pay-for Performance

In 2023, our executive compensation program received substantial support from our shareholders, with approval by approximately 89% 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 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 2023, 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 2023, based on a comparative analysis of companies in our Peer Group (described below), we maintained base salary compensation for Dr. Kewalramani, Dr. Altshuler, Mr. Wagner and Mr. Arbuckle. Under his employment agreement, Dr. Leiden does not receive a base salary for his role of Executive Chairman.
Annual Cash Bonus: We maintained the target cash bonus, which is a percentage of base salary, for all of our NEOs. Dr. Leiden does not receive an annual cash bonus pursuant to his employment agreement. The company’s outstanding performance in 2023, as described above, resulted in the board determining that the company achieved a leading rating for 2023 (a rating of 150 out of a potential 150), and the payment of above-target annual cash bonuses. Please see Overview of Company Performance Rating & Achievement in 2023.

VERTEX PHARMACEUTICALS INCORPORATED - 2024 Proxy Statement     55

Long-Term Equity Program:
In 2023, based in part on a comparative analysis of companies in our Peer Group, we maintained the target equity grant for Dr. Kewalramani and we maintained the target equity grants for our other NEOs. For his fourth year as Executive Chairman, Dr. Leiden received equity grants of $6.5 million pursuant to the terms of his employment agreement. Under his employment agreement, Dr. Leiden will continue to receive equity grants for the fifth year in his Executive Chairman role.
We maintained our mix of equity granted under our compensation program with 50% of the awards consisting of PSUs that vest solely upon achievement of specific performance goals and 50% consisting of time-vesting RSUs. This mix rewards stock price appreciation and incentivizes long-term tenure at the company. The number of RSUs 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-based awards. We replaced the performance-specific multiplier with a performance-specific multiplier range, as outlined under Annual Equity Awards on page 69 below.
We achieved two of the three goals established for the 2021 non-financial based PSU awards and the maximum level of performance for the 2023 financial-based PSU awards, resulting in 100% and 200% payouts, respectively, under these awards in February 2024.
In early 2024, the MDCC granted new awards of PSUs and 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 measured from the date of grant, and are tied to net product revenue in 2024, while the remaining 50%, which cliff vest after three years, are tied to specific clinical and research milestones over a three-year period.

Shareholder Engagement

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.

During 2023, we solicited feedback regarding our corporate governance practices from our top 40 shareholders representing approximately 65% of our outstanding shares. Our integrated outreach team included leaders from our Investor Relations, Human Resources, Corporate Responsibility, Corporate Communications, and Legal teams, and we discussed numerous topics of shareholder interest, including our business strategy, R&D approach, diversity initiatives and metrics, employee engagement and development, corporate governance, political and lobbying disclosures, executive compensation, and environmental sustainability matters.

Compensation Governance Practices

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

Detailed Discussion and Analysis

Compensation Philosophy

Our MDCC regularly reviews the elements of the individual compensation packages for our executive officers or NEOs, for 2015 were:

Dr. Jeffrey M. Leiden, our Chairman, Chief Executive Officer and President
Ian F. Smith, our Executive Vice President and Chief Financial Officer
Stuart A. Arbuckle, our Executive Vice President and Chief Commercial Officer
Dr. Jeffrey Chodakewitz, our Executive Vice President, Global Medicines Development and Medical Affairs and Chief Medical Officer
•Dr. David M. Altshuler, our Executive Vice President, Global Research and Chief Scientific Officer
to ensure that they continue to support the achievement of the following primary objectives:

Performance-based Executive Compensation Program
Our compensation program is designed to attract, retain, and motivate talented, experienced, and experiencedhigh-performing individuals across all areas of our business and to 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. Our MDCC seeks to achieve this objective through a program consisting of the following principal components:medicines; and

Evaluated and adjusted, as appropriate, each year based upon a detailed market assessment as well as each executive’s contributionsensure that the vast majority of compensation is tied to company and individual performance.Determined each year based on individual and company performance based on achievement against operating and financial goals approved by the committee at the beginning of each year, as well as performance-based and values-based evaluations of individual performance.Aligns the incentives of our executive officers with shareholder interests and rewards the creation of shareholder value:
(1) In 2015, granted options and performance-accelerated restricted stock based on 2014 individual and company performance pursuant to a share-based program.
(2) In 2016, adopted a new "value-based" program, reducing reliance on stock options and introducing performance restricted stock units to increase linkage between pay and performance.
Executive Summary
We

Our executive officers have adopted significant changes tohad long and varied careers and possess diverse 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 in CF, a landmark gene-edited cell therapy for SCD and TDT, 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 and board seek to connect 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 goals that are used in particular,our equity awards. Our company goals address several key objectives, including increasing revenues from our current products, achievement of 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 and board 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 equity compensation component, which were implementedlong-term. Our MDCC and board expect to continue seeking balance in early 2016. The new equity compensation program reflects fundamental changesthe use of financial metrics and R&D goals to motivate our executive team to achieve financial 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 performance, competencies, experience and financial profilespecific role accountabilities, and feedback we received fromdo not solely benchmark at any particular level. Our MDCC retains flexibility to structure compensation based on good governance practices, our shareholders. While we continually engage in dialogue withobjectives of building our company and creating value for our shareholders, we increasedand, most importantly, discovering, developing, and delivering transformative medicines for patients who can benefit from them.

Compensation Decision-Making Process

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 levelCEO, other executive officers, and senior leaders. The MDCC evaluates the performance of engagementour CEO and other executive officers. Our CEO, our Executive Chairman, and our human resources group assist the MDCC in responseevaluating the performance of our other executive officers, including the NEOs other than the CEO. Our CEO does not make any recommendations to the declineMDCC regarding CEO compensation and does not participate in support we received forthe portions of MDCC meetings or meetings of the board of directors when CEO compensation is discussed or determined. Similarly, our advisory say-on-pay proposal at our 2015 annual meeting. OverExecutive Chairman does not make any recommendations to the past year, we held specific discussionsMDCC regarding his compensation and does not participate in portions of MDCC meetings or meetings of the board of directors when Executive Chairman compensation is discussed or determined.

The members of the MDCC, each of whom is an independent director, make a recommendation regarding executive compensation with shareholders representing approximately 75%to the independent directors of the board, who together make final compensation decisions for the CEO and other executive officers based on these recommendations.

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).

VERTEX PHARMACEUTICALS INCORPORATED - 2024 Proxy Statement     57

Annually, the MDCC engages an independent compensation consultant to conduct an analysis of our outstanding stock.

Similar to other development-stage companies and consistent with market practices, our long-term equity grants historically have been weighted toward granting a consistent number of stock options, which we refer tocompensation program as a share-based program. Overwhole, 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 last several years,meeting of the value of annual compensation reportedMDCC that occurs in the Summary Compensation Tablessummer 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 2023, the MDCC continued its engagement with Pearl Meyer as its independent compensation consultant. Pearl Meyer is compensated 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 elements of executive compensation on a competitive basis, the MDCC and our namedboard of directors considers information about the compensation practices of a representative group of companies with whom we compete for executive officers has increased duetalent (our “Peer Group”). We conduct a detailed analysis to our share-based approach,select companies for this Peer Group on the strong performancebasis of oursimilarity and complexity of business model. While revenue and increases in our share price. During this periodindustry are common peer selection criteria, we also matured from a development-stage company to a commercial-stage global biotechnology company with a strong financial profile and a clear path to sustained revenues and earnings growth. In early 2016, consistent with market practices for companies at our stage of development we transitioned from a share-based approach to a value-based approach for our long-term equity program.

Adoption of New "Value-based" Equity Compensation Program
As discussed in more detail below, in response to the feedback we received during our shareholder engagement efforts, we adopted for 2016 a new approach for granting equity and equity-based compensation to our executives, including our named executive officers. Under this program awards of equity compensation are no longer based upon a targeted number of shares. The value-based program provides that:
Annual awards to our executives will be sized based upon a target grant-date value, which will be determined based upon a holistic analysis of market data, business needs and other considerations that the MDCC deems relevant;

Notice of Annual Meeting of Shareholders and 2016 Proxy Statement | 39

COMPENSATION DISCUSSION AND ANALYSIS - OVERVIEW (continued)

The targeted values are expected to result in grants with significantly fewer shares than the prior, share-based approach;
The awards themselves will be comprised ofuse a mix of award types,quantitative and qualitative factors in order to establish our peers, including the following:

Factor ConsideredWhat We Look For
Similar industryBiotechnology or pharmaceutical industry
Importance of medicines to patients and societyTransformative medicines for serious diseases; therapeutics for unmet needs
Recognized focus on innovation  Breakthrough Therapy designations, priority review and/or other markers indicating unmet need
Global operationsSignificant operations both within and outside the U.S.
Commercial operationsMarketing and selling approved medicines
Significant R&D investmentGreater than $2.2B or 25% of revenue
Number of employeesGreater than 1,200 employees
Market capitalization and significance to broader economyMarket cap at least ¼ our size and/or inclusion in S&P 500 or Nasdaq 100
Labor market competitorCompanies we compete with for executive talent
Companies that use Vertex as a peerInclusion of Vertex in proxy reported peer group

It is unlikely for companies to align on all of the factors listed above; therefore we look for companies meeting a majority of the valuecriteria although we place greater weight on companies focused on innovation and the importance of each award will have performance features (e.g., performance vesting or stock option awards); and

The size of annual equity awards also takes into consideration individual performance results as well as adherence to corporate values, including our uncompromising commitmentmedicines to patients and focus on innovation.
Under the value-based program, our CEO will be eligible for annual equity awards with a value between zero and $14 million (with the actual value depending upon his performance),society as compared to the 2015 grant value of $23.3 million under the prior share-based approach. Our other named executive officers will be eligible for annual equity awards with values between zero and $4.5 million, as compared to the 2015 grant values for such officers, which ranged from $6.6 million to $7.5 million.
Shareholder Feedback and Response
The following chart summarizes what we heard from our shareholders and how we responded in our revised equity compensation program.
CONCERNS WE HEARDWHAT WE DID
Magnitude of awards resulting from our share-based equity programChanged to a value-based equity program which should reduce grant date fair-value of our CEO's equity awards by 40% in 2016
Exclusive use of time-based equityImplemented performance-contingent restricted stock unit awards, significantly reducing our reliance on time-based stock option awards
Rigor of vesting terms for one-time retention awards granted in 2014Implemented balanced financial and non-financial metrics with a substantial risk of forfeiture for performance-contingent restricted stock unit awards
Dilution created by compensation programChanged to value-based program which should significantly reduce dilution; for example, the number of shares at target subject to CEO equity awards will decrease by approximately 44% in 2016
In order to ensure that our compensation program is aligned with the achievement of strategic objectives and company performance, we continue to have approximately 90% of the compensation for our CEO and our other named executive officers performance-linked through annual cash bonuses, restricted unit awards and stock-option awards.
In reviewing the compensation information included in this proxy statement, it is important to note that the equity compensation inbelieve these tables for 2015 reflects compensation received under the program we had in place prior to the changes implemented in early 2016.

Performance and Operational Results
We are dedicated to developing transformative medicines for people with serious diseases. Over the last several years, we have met or exceeded our goals, building on our leadership position in the treatment of CF, advancing and broadening our

Notice of Annual Meeting of Shareholders and 2016 Proxy Statement | 40

COMPENSATION DISCUSSION AND ANALYSIS - OVERVIEW (continued)

pipeline, increasing revenues and establishing a strong financial profile. We have two medicines that together are approved to treat approximately 25,000 patients with CF, or approximately one third of the CF population worldwide. These medicines are the first, and only, medicines that treat the underlying cause of CF, and we believe they have fundamentally changed the way eligible patients can be treated. In addition, we have a strong CF pipeline, with multiple drug candidates, that may allow us to help all patients with this rare and life-shortening disease.
Specifically, in 2015 we:
Increased the number of CF patients who are eligible for treatment with our medicines by approximately 700%:
Obtained U.S. and E.U. approval of ORKAMBI and successfully launched ORKAMBI in the U.S.
Continued to increase the number of patients eligible to receive KALYDECO through label expansions.
Advanced our CF development pipeline to help us reach our goal of developing treatments for all CF patients:
Progressed Phase 3 development of VX-661 in combination with ivacaftor, which may enhance treatment for patients currently eligible for ORKAMBI.
Initiated development of VX-152 and VX-440, next-generation correctors that could allow us to increase the benefits our medicines provide to CF patients and increase the number of CF patients eligible for our medicines.
In-licensed from Parion Sciences, Inc. VX-371, an investigational ENaC inhibitor, which provides us an approach that, if successful, could be used as a treatment for all CF patients regardless of their CFTR mutation.
Established a collaboration with CRISPR Therapeutics AG pursuant to which we are seeking to discover medicines aimed at the underlying genetic causes of human diseases, including CF, using CRISPR-Cas9 gene editing technology.
Expanded and diversified our pipeline and research efforts beyond CF:
We are pursuing DNA damage repair, an important emerging area for the development of cancer medicines. We are evaluating VX-970 and VX-803, our most advanced oncology drug candidates, in early-stage clinical trials.
In pain, a Phase 2 clinical trial of VX-150 is ongoing, and we expect to begin clinical development of VX-241 in 2016.
Grew revenues, maintained our financial strength and became cash flow positive in the fourth quarter of 2015, allowing us to continue to invest significantly in R&D and return value to shareholders:
Increased CF net product revenues by 112% compared to 2014, with significant additional increases expected in 2016.
Entered 2016 with approximately $1.0 billion in cash, cash equivalents and marketable securities.
Our accomplishments reflect the leadership and focus of our executive team in driving exceptional company performance and have led to consistently high shareholder returns and increasing CF net product revenues.

Key Compensation Decisions
The primary elements of our annual executive compensation program are base salary, annual cash bonus and equity awards. The key recent decisions that our MDCC and board made are as follows:
Base Salary: As discussed in our proxy statement for our 2015 annual meeting, in December 2014 our board approved a change in our CEO's base salary from $1,100,000 to $1,300,000. This change was related to the extension of the term of our CEO's contract and is alignedcompanies with the median CEO paygoal of our Peer Group. During 2015, our board also approved adjustments to the base salaries for our other NEOs to align their salaries closer to the median levels for our Peer Group.
Annual Cash Bonus:maintaining a group of comparators comprised of at least twelve companies.

As a result of our exceptional performance in 2015, our board approved annual cash bonuses atthis analysis, and on the high-endbasis of the rangecriteria listed above, the MDCC approved the following comparator companies for each2023, which were the same comparator companies used in 2022. In 2024, we expect we will replace Seagen Inc. due to its acquisition by Pfizer.

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 NEOs.

Long-Term Equity Program:
In 2015, we granted options and performance-accelerated restricted stock under the share-based approach that we utilized until early 2016. Dr. Leiden, Mr. Smith, Mr. Arbuckle and Dr. Chodakewitz received options and restricted stock in February 2015 reflecting their individual performance in 2014 and a mid-year option grant. Dr. Altshuler received a sign-on restricted stock award in January 2015 and a mid-year option grant.
In early 2016, we implemented significant changes to our equity compensation program (i.e., the adoption of the value-based equity program, which is summarized above and described in more detail below and will be reflected in our Summary Compensation Table for 2016 in next year's proxy statement).
As a resultrelevant peers in the biotechnology industry. In addition, the Peer Group companies have many of the changes to our equity compensation program,business model characteristics that we are decreasing substantially the value of compensation providedseek in the form of stock options, reducing the value of compensation delivered in the form of time-vested restricted stock, and in order to increase the link between performance and compensation introducing performance stock units, or PSUs. As a result of these changes, the grant date fair-value of our NEOs' total equity compensation under the annual program will decrease by 40% to 45%comparator companies as set forth in the following chart.

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 Radford, Mercer SIRS, and Willis Towers Watson, but does not make any material compensation decisions based on any particular company participants in such surveys.

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 revenues and greater than $10 billion market capitalization. The MDCC reviewed the compensation practices for the following broader life science industry companies when considering compensation for Mr. Arbuckle:

Elements of Annual Compensation

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 the NEOs, this means compensation is primarily in the form of equity and directly tied to changes in shareholder value over time. For our 2023 equity grants, we maintained our mix of equity awards, including PSUs and time-based RSUs.

Compensation Program

As shown in 2015 included the sign-on equity grant he received when he became an employeefollowing charts, our compensation program places significant weight on performance-based compensation, with 90% of our NEO compensation tied to performance, or “at-risk” if performance is not achieved.

The charts above generally represent the values in January 2015.

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 ElementPerformance Link
Annual Cash BonusAnnual bonus dependent on both company and individual performance factors
COMPENSATION DISCUSSION AND ANALYSIS - OVERVIEW (continued)
Equity Awards
Grant date value of equity awards based on target award values by level with differentiation for individual performance

Estimates for value of 2016 equity-based awards are based on our methodology for determining the grant-date fair value, including underlying assumptions for calculating these values as set forth in Note N to our consolidated financial statements included in our 2015 Annual Report on Form 10-K and are subject to adjustment.
Pay-for-Performance Alignment
We considered pay and performance alignment based on “realized” and “realizable” perspectives. The MDCC’s independent consultant, Pearl Meyer & Partners, or Pearl Meyer, conducted both the realized and realizable pay and performance analyses set forth below, comparing our executive payValue of shares granted based on target set by MDCC and Board, adjusted for individual performance ranging from 0% for below target individual performance, 100% at target performance, and up to 150% for above target individual performancePSU Awards50% of PSUs with range of shares earned 0% to 200% of target based on one year financial metrics (vesting in equal installments over a three-year period)50% of PSUs with range of shares earned 0% to 200% of target based on three-year non-financial metrics (cliff-vesting after three years)Time-Based RSUsValue of awards increases or decreases based on stock price over the three-year vesting periodWe consider our time-vesting RSU awards to be performance-based awards because the target number of RSUs awarded may be adjusted based on the corresponding executive’s individual performance for the relevant performance period as well as the resulting value dependent upon increases or decreases in our stock price over the three-year vesting period

More specifically:

PSU Awards. Our CEO and executive vice presidents (“EVPs”) receive 50% of their annual equity compensation in the form of PSUs. 50% of the number of PSUs are eligible to vest based on the achievement of financial goals and the remaining 50% of the number of PSUs are eligible to vest based on the achievement of non-financial goals. The financial PSUs, if earned, vest in annual installments over a three-year period measured from the date of grant, and the non-financial PSUs, if earned, cliff vest after three years. The potential shares earned pursuant to 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 the financial and non-financial performance goals. The MDCC selected revenue and clinical development 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. Our CEO and EVPs receive 50% of their annual equity compensation in the form of time-based RSUs that vest over a three-year period measured from the date of grant. With 50% of the annual long-term incentive award at risk pending successful execution of our strategic objectives through the grant of PSUs, we believe that it is important to have the remaining half 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 with the interests of our shareholders.

Base Salary

The MDCC recommends base salaries for our executive officers based on multiple factors, including a competitive market analysis on a position-by-position basis. Annually, the MDCC reviews a comparison of each executive’s prior year base salary and cash bonus opportunity, measured at the target level, to salaries and cash bonuses reported for executives with similar responsibilities at Peer Group companies. 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 compensation at Peer Group companies, and taking into consideration the executive’s base salary for the previous year or years, the MDCC recommends an appropriate base salary for each executive officer, subject to final approval by our independent directors. Our current base salaries reflect each individual executive’s past and expected future contributions, performance, experience, specific responsibilities relative to peer benchmarks, and competitive positioning within the range around the median base salaries for our Peer Group companies' paycompanies.

Dr. Kewalramani’s base salary for 2023, as our CEO and performance. Our three-year TSR approximatedPresident, was maintained at $1.50 million, based on multiple factors, including her contributions as CEO and President, expected future contributions, experience and knowledge. We also maintained the 72nd percentilebase salaries for Dr. Altshuler, Mr. Arbuckle and Mr. Wagner based on a comparative analysis of compensation in our Peer Group. Our CEO and NEOs average three-year realized compensation approximated the 53rd and 67th percentiles of our Peer Group’s CEOs and NEOs. Our CEO and NEOs' average three-year realizable compensation approximated the 78th and 84th percentiles of our Peer Group’s CEOs and NEOs. Based on these results, we believe that our pay programs are effective at ensuring that pay levels for our executives are aligned with performance.

Realized compensation is compensation actually received during the year based on the executive’s total compensation as calculated under SEC rules, excluding the grant-date fair value of equity awards and substituting the actual value realized on the exercise of options and the vesting of restricted stock as set forth in our “Total Realized Compensation Table” on page 69 of this proxy statement. Accordingly, it excludes unvested grants and other amounts that will not actually be received, if at all, until a future date.
Realizable compensation is actual salary received, payouts from non-equity incentive plan compensation, the value of time-based shares granted during the period, the in-the-money value of stock options granted during the period, and the value of performance stock or units granted during the period, assessed at payout value, if applicable, and based upon the target value of underlying shares if the performance period has not yet concluded. All equity grants are valued as of December 31, 2015, the last day of the three-year performance period. With respect to options, the value is based on the difference between the exercise price and the fair market value of the company's stock on December 31, 2015. It excludes grants of cash or equity awards outside the three-year performance period.
As discussed above, our business has performed exceptionally over the last several years, and the compensation paid to our NEOs during 2013-2015 shows a strong connection to our TSR relative to our Peer Group, as shown in the graphs below. Data points that are within the shaded area designate Peer Group companies that exhibit pay-for-performance alignment.

Broad-Based Equity Program While Reducing 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. Over the last several years, we have modified our equity compensation programs. These modifications are consistent with modifications other biotechnology companies have made as they matured from development-stage companies to commercial-stage companies with a strong financial profile. As a result of these changes, we granted, on an absolute basis, equity awards representing 33%41% fewer shares of common stock in 20152023 as compared to 20122019 and reduced our "burn rate"“gross burn rate” to 0.8% in 2023 from 3.6%1.4% in 2012 to 2.1% in 2015.

COMPENSATION DISCUSSION AND ANALYSIS - DETAILED DISCUSSION AND ANALYSIS

Compensation Philosophy and Compensation Decision-Making Process
Compensation Philosophy
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 executive officers with the interests of our shareholders as we seek to create value through the discovery, development and commercialization of transformative medicines. Our NEOs have had long and varied careers, and possess experiences and skills that make them extremely valuable members of our executive team and to our company as a whole. They have been instrumental in building Vertex into the company it is today, with a leadership position in the treatment of CF, an advancing pipeline that has been significantly broadened over the last several years, increasing revenues and an established strong financial profile.
Our MDCC and our board of directors seeks to connect the achievement of our strategic objectives with our compensation program in a number of ways, including through company goals that underlie our annual cash bonuses and the performance goals which are now included in our equity awards. Our company goals involve a mix of goals relating to revenues from our current products, achievement of research and development objectives, our organizational capability and maintenance of our financial strength. These objectives are selected specifically because they are considered by our board to be objective milestones that our company must achieve if it is to maintain its movement towards significant revenue growth and sustainable profitability. Our MDCC and board of directors expects to continue to seek to balance the use of financial metrics and research and development goals in order to motivate our executive team to increase revenues and manage operating expenses, while providing appropriate incentives for our management to continue to make appropriate investments in our business.
In determining compensation, we consider compensation paid to similar companies as reference points, but do not strictly benchmark or target compensation at any particular level. Rather, the MDCC retains flexibility to structure compensation based on good governance practices and our objectives of building our company and creating shareholder value.
Compensation Decision-Making Process
Role of MDCC and Chief Executive Officer in Setting Executive Compensation
The MDCC has responsibility for overseeing the design, development and implementation of the compensation program for our chief executive officer and other NEOs. The MDCC evaluates the performance of our chief executive officer and the performance of the other executive officers. Our chief executive officer and our senior vice president, human resources, assist the MDCC in evaluating the performance of our other executive officers, including the named executive officers other than the chief executive officer. Our chief executive officer does not participate in board discussions relating to his compensation, and the other NEOs do not play a role in their own compensation determination.
The members of the MDCC, each of whom is an independent director, together with the other independent directors, make final compensation decisions for the CEO’s and other executive officers’ compensation levels based on these assessments.
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 has engaged a compensation consultant to conduct an analysis of all elements of compensation paid to our executive officers, including our NEOs, compared to similar elements paid to similarly situated executives at companies in our peer group and to provide a written report and presentation of findings at the meeting of the MDCC that occurs in July each year. In 2015, the MDCC selected Pearl Meyer to conduct and present this analysis to the MDCC.  In addition, our MDCC also engaged Pearl Meyer in order to assist us in making significant modifications and improvements to our compensation program that were implemented in early 2016.
Pearl Meyer only provides, and is compensated for, advice provided to us at the direction of the MDCC.  The MDCC considered the following information provided to it by Pearl Meyer:

Notice of Annual Meeting of Shareholders and 2016 Proxy Statement | 46

COMPENSATION DISCUSSION AND ANALYSIS - DETAILED DISCUSSION AND ANALYSIS (continued)


Pearl Meyer’s policies and procedures designed to prevent conflicts of interest;
that fees paid by us to Pearl Meyer represent less than 1% of Pearl Meyer’s total annual revenues;
the absence of business and personal relationships between the compensation consultant and the MDCC or any of our executive officers; and
that Pearl Meyer’s partners, consultants and employees who provide services to the MDCC, and their immediate family members, do not own shares of our common stock.
Based on these, 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 make judgments about elements of executive compensation on a competitive basis, the MDCC and our board of directors considers information about the compensation practices of a representative group of companies with whom we compete for executive talent, or Peer Group. We select companies for this Peer Group on the basis of similarity and complexity of business model. In order to assess business model similarity, we consider a number of factors including the following:
Factor ConsideredWhat we look for
Similar industryBiotechnology or pharmaceutical industry
Importance of medicines to patients and society

Transformative medicines for serious diseases; therapeutics for unmet needs
Recognized focus on innovation

Breakthrough Therapy designations, priority review and/or other markers indicating unmet need
Global operationsSignificant operations outside the U.S.
Commercial operationsMarketing and selling approved medicines
Significant R&D investmentGreater than $700M or 50% of revenue
Number of employeesGreater than 750 employees
Market capitalization and significance to broader economy

Market cap at least ¼ our size and/or inclusion on S&P 500 or NASDAQ 100
Labor market competitorCompanies we compete with for executive talent
Companies that use Vertex as a peerInclusion of Vertex in proxy reported peer group
We also consider revenue but it is not a factor we emphasize because we do not believe revenue adequately reflects business model similarity or complexity in the biotechnology industry. A company with similar revenues may not have global or commercial operations like we have nor may it focus on innovative therapies, but rather on generic medicines, which we believe results in a different business model requiring less research and development investment. Moreover, a company with similar revenues may not focus on innovative therapies such as those designated as a Breakthrough Therapy by the Food and Drug Administration, which expedites the development and review of medicines that are intended to treat a serious condition and preliminary clinical evidence indicates that the medicine may demonstrate substantial improvement over available therapy on clinically significant endpoints. As a result, we believe the factors listed above provide a better way to assess similarity versus a reliance on the combination of revenue and industry. We also note that it is unlikely for companies to align on all the factors listed above, so we look for companies meeting a majority of the criteria although we place greater weight on companies focused on innovation and importance of medicines to patients and society as we believe these are the key drivers of our business model. We also focus on market capitalization because we believe it is an indicator of the complexity of a company's 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 on the basis of the criteria listed above, the MDCC selected the following comparator companies for 2015.

COMPENSATION DISCUSSION AND ANALYSIS - DETAILED DISCUSSION AND ANALYSIS (continued)


We do not strictly benchmark to a particular level of compensation relative to compensation levels at the Peer Group companies, but rather make a judgment 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 Radford, Mercer SIRS and Towers Watson, but does not make any material compensation decisions based on any particular company participants in such surveys.

Notice of Annual Meeting of Shareholders and 2016 Proxy Statement | 49

COMPENSATION DISCUSSION AND ANALYSIS - DETAILED DISCUSSION AND ANALYSIS (continued)


Elements of Annual Compensation
Our executive compensation program is structured to use a mix of base salary, annual performance-based cash bonus, and long-term equity compensation awards in the form of stock options and restricted stock/restricted stock unit awards to incent and reward those individuals who make the greatest contribution to our company performance over time. For the NEOs, this means compensation is primarily in the form of equity and directly tied to changes in shareholder value over time.
The elements of our annual executive compensation program are base salary, annual cash bonus, equity awards in the form of stock option awards and restricted stock/restricted stock unit awards. Each year we review the balance of the elements of our executive compensation program to ensure that they are appropriately designed in light of our goals to align the program with our shareholders’ interests, the competitive environment and our business strategy. In early 2016, we implemented a revised long-term equity program, changing from a share-based approach to a value-based approach, deemphasized stock options and replaced time-based restricted stock awards that could accelerate based on performance goals with a mix of performance contingent restricted stock unit awards and time-based restricted stock unit awards.
2015 Program (Prior Share-based Program)

COMPENSATION DISCUSSION AND ANALYSIS - DETAILED DISCUSSION AND ANALYSIS (continued)


Performance-Linked 2015 Program

In line with our objectives, a significant portion of our NEOs' 2015 compensation was in the form of equity, specifically:
Stock options.  Our NEOs received 70% of their equity in the form of stock options that vest over a four-year period. We have historically heavily weighted our equity program toward stock options given our stage of development at the time.
Performance accelerated restricted stock (PARS).  Our NEOs received 30% of their equity in the form of PARS that cliff-vest after four years with the opportunity to earn and vest earlier if certain performance criteria is met related to our long-term strategic objectives. For 2015, the performance acceleration vesting criteria were as follows:
The vesting accelerates for the first half of the shares upon (i) U.S. net ORKAMBI sales for a 12-month period ending on a calendar quarter being equal to or greater than $1.25 billion or (ii) completion of a clinical trial that establishes a proof-of-concept for a next-generation CFTR corrector.
The vesting accelerates for the second half of the shares upon (i) worldwide net ORKAMBI sales, excluding U.S. net ORKAMBI sales, for a 12-month period ending on a calendar quarter being equal to or greater than $500 million or (ii) completion of a pivotal clinical trial of a non-CF drug candidate that provides sufficient data to support a new drug application.
We have historically granted PARS as a combination of a retentive tool and an incentive tool to focus our executives on achieving strategic objectives. As discussed below, we have changed our equity program and are effectively replacing PARS with PSUs.

Notice of Annual Meeting of Shareholders and 2016 Proxy Statement | 51

COMPENSATION DISCUSSION AND ANALYSIS - DETAILED DISCUSSION AND ANALYSIS (continued)


Performance-Linked 2016 Value-Based Program
Under our new value-based program, we maintained our focus on performance-linked elements as follows:
Compensation ElementPerformance-Link
Annual Cash Bonus
4    Annual bonus dependent on company performance factors
4    Annual bonus dependent on individual performance
4 Potential range of bonus 0% to 225% of target bonus

4   Value of awards increases or decreases based on increases or decreases in stock price
Time-Based Restricted Stock Unit Awards
4   Number of shares granted based on individual performance
4   Value of awards increases or decreases based on increases or decreases in stock price
As mentioned above, we have made significant changes to our equity program over the last year due to the evolution of our company as well as feedback we received from our engagement with shareholders. We have matured from a research and development company to a global biotechnology company with a market cap ranging from twenty to thirty billion dollars over the last year. We became cash flow positive in the fourth quarter of 2015 and by the end of 2015 were marketing two commercial medicines that are the first and only medicines to treat the underlying cause of CF and had expanded our global footprint to support the sale of KALYDECO and ORKAMBI. Because of these accomplishments, we believed it was the right time to modify our equity compensation program to better fit where we are in our stage of growth. As a result, we made the following changes:
Adopted a value-based approach to granting equity awards;
Decreased emphasis on stock options;
Replaced performance accelerated restricted stock with performance stock units tied to a balance of financial and non-financial metrics; and
Modified our mix of long-term incentive awards to provide balance between our incentive, shareholder alignment and retention objectives of our equity awards.
More specifically, under the revised program:

Stock Options. Our NEOs will receive 30% of their annual target equity value in the form of stock options that will vest over a four-year period. This is a significant shift away from the 70% weight under the prior program that we believe aligns better with our current stage of growth. We are continuing stock option awards because we believe stock options are performance-based and provide alignment with shareholders as executives are rewarded for broad corporate performance only if the stock price appreciates.
Performance Stock Units. Our NEOs will receive 35% of their annual equity compensation in the form of PSUs, which we introduced in 2016. The PSUs will vest, if at all, based half on financial and half on non-financial goals. The potential range of shares issuable pursuant to the performance stock unit awards range from 0% to 200% of the target shares based on financial and non-financial measures. Fifty percent of PSUs that could be earned have a one-year performance period with the amount actually earned dependent upon Vertex’s net product revenue performance for 2016 and with vesting of the earned shares in three equal installments over a three-year period. The MDCC selected a one-year performance period because of the difficulty in forecasting financial metrics at our stage of growth beyond a one-year period. The remaining 50% of PSUs that could be earned have a three-year performance period with the amount actually earned dependent upon the achievement of multiple clinical development milestones (i.e., advancement of CF and non-CF therapies in the clinic) and with the earned shares cliff vesting at the end of the three-year performance period. The MDCC selected revenue and clinical development milestones because

Notice of Annual Meeting of Shareholders and 2016 Proxy Statement | 52

COMPENSATION DISCUSSION AND ANALYSIS - DETAILED DISCUSSION AND ANALYSIS (continued)


shareholders and analysts rely heavily on these metrics to understand the underlying condition and the performance of our business. In addition, achievement of these metrics would indicate successful execution toward our long-term strategic objectives of expanding our CF franchise and diversifying our product portfolio.
Time-based Stock Units. Our NEOs will receive 35% of their annual equity compensation in the form of restricted stock units that will vest over a three-year period, subject to continued service. We believe that with a majority of the annual long-term incentive award at risk based on our stock price appreciation and successful execution of our strategic objectives, it is important to have a smaller portion of the annual award focused on retaining our key executive talent. As a result, we believe time-based restricted stock units encourage retention while also providing immediate alignment with our shareholders.
No Other Awards. No off-cycle grants were made in 2015 to our NEOs, nor are there any plans to make such grants in 2016.
In total, approximately 90% of our CEO's 2016 compensation is performance-linked:

COMPENSATION DISCUSSION AND ANALYSIS - DETAILED DISCUSSION AND ANALYSIS (continued)


Base Salary (5%-15% of Annual Compensation)
The MDCC recommends base salaries for each of our executive officers on the basis of a market analysis, on a position-by-position basis. Annually, the MDCC reviews tables showing a comparison of each executive’s prior year base salary and cash bonus opportunity, measured at the target level, to salaries and cash bonuses reported for executives with similar responsibilities at comparable companies. We do not strictly benchmark to a particular level of compensation relative to compensation levels at the Peer Group companies, but rather make a judgment about where each executive should fall in comparison with executives with similar responsibilities at the Peer Group companies, taking into account the executive’s general level of experience and capability, the significance of his or her job responsibilities to the achievement of our business strategy and company goals, and general performance over time, including demonstration of the values and desirable behaviors under our core values program. On the basis of that information, including compensation at Peer Group companies, and taking into consideration the executive’s base salary for the previous year, the MDCC recommends an appropriate salary for each executive officer, subject to final approval by our independent directors. Our current base salaries for our named executive officers approximate the median base salaries for counterparts at companies in our Peer Group.
In December 2014, our board negotiated an extension to the term of Dr. Leiden’s employment agreement, which included a salary increase, effective January 1, 2015. Our board and MDCC considered, among other factors, our success during his tenure as our CEO and the salaries of the CEOs for companies in our Peer Group, and increased Dr. Leiden's salary to the median of the salaries of the CEOs in our Peer Group. In 2015, the MDCC reviewed and adjusted base salary levels for our other NEOs, other than Dr. Altshuler who joined us in early 2015, based on market data regarding salaries at our Peer Group companies. The following table sets forth our NEOs annual base salaries at the end of 2014 and 2015, together with information regarding a comparison of their base salaries to comparable executives at companies in our Peer Group.

company’s annual performance rating.

For 2015,2023, the MDCC recommended and the board of directors 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 revenue goals for marketed or late-stage products were designed to incentivize increasing access to our medicines through approvals of new transformative medicines and therapies, label-expansions for our existing medicines, and obtaining government reimbursement in ex-U.S. markets. Our commercial manufacturing, innovation, quality and operations goals were designed to incentivize supply chain resilience, efficiency in delivery of our CF 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 improvements to our organizational structure, processes, and systems as well as to ensure continued focus on our values and culture of innovation and inclusion. We believe this mix of goals provides an appropriate balance between our near- and long-term goals of significant revenue growthobjectives and achieving sustainable profitability. between pipeline, financial, and organizational development objectives.

Goals - Marketed and Approval-StageLate-Stage Products

KALYDECO. KALYDECO net product revenues increased by 36% from $463.8 million in 2014

In 2023, we made significant progress with respect to $631.7 million in 2015. The increase was due to additional patients being treated with KALYDECO as we completed reimbursement discussions in various jurisdictions,our marketed and increased the number of patients eligible to receive KALYDECO through label expansions and the maintenance of high compliance rates.

ORKAMBI. In 2015, we obtained timely approval of ORKAMBI in the U.S. and European Union, increasing the number of patients eligible for our medicines by approximately 20,500. As of December 31, 2015, more than 4,500 patients had initiated treatment with ORKAMBI, and in 2015 we had ORKAMBI net product revenues of $350.7 million as compared to no ORKAMBI net product revenues in 2015.
Overall, we increased CF net product revenues to $982.3 million in 2015, an increase of 112% compared to 2014, with significant additional increases in CF net product revenues expected in 2016.

CF net product revenues increased to $9.87 billion, up 11% as compared to 2022. Our CF net product revenues exceeded the mid-point of our initial CF net product revenues guidance by $244.2 million ($9.87 billion actual as compared to the mid-point of our initial guidance of $9.63 billion) as a result of continued strong uptake of TRIKAFTA/KAFTRIO in ex-U.S. markets and the continued performance of TRIKAFTA in the U.S., following the launch of TRIKAFTA in children with CF 2 to 5 years of age.
We completed key cross-functional commercial readiness for the launch of CASGEVY, including with respect to onboarding authorized treatment centers, and continued progress with policymakers, payers and patient advocacy groups.
Developed and completed innovative go-to-market model and launch plan for acute pain in the U.S. and made significant progress in building our pain organization with key critical hires.

2023 Individual Performance Ratings - Overview

The MDCC evaluates executives’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 his or hertheir 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”“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 based on whether the decisions made by the executives were consistentconsidered along with theseour leadership competencies, which reflect our core values and what is in the best interestsleadership behaviors that we believe lead to successful execution of the company in the long term. Under our Values Into Practice program, westrategy 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 core values,company culture, and the performance ratings assigned to them incorporate our MDCC and board’s assessment of the strength of their leadership with respect to, and demonstration of, values-based behavior. This evaluation results in ratings of “not demonstrating,“inconsistent demonstration,” “living the values”values,” or “exemplary demonstration.” The possible individual performance ratings under this program are as set forth in the following table:

Taking into account all of the factors raised in the discussion and the assigned individual performance rating, the MDCC assigns an individual performance factor for each NEO within the ranges set forth below that, along with the annual corporate performance factor, determined each NEO’s annual bonus. 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.
2015 The results-based and behaviors-based evaluations for our CEO is 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.

Annual Equity Awards

Value-Based Guidelines for Annual NEO Equity Grants

Under our compensation program, equity awards grantedfor our CEO and EVPs are calculated by multiplying the individual’s target equity award by his or her performance rating-based equity modifier. In 2023, we replaced the performance-specific multiplier with a performance-specific multiplier range, as outlined below. Prior to the 2023 performance year, our namedcompensation program provided a specific equity modifier for each performance rating. Our new practice increases the performance sensitivity of the program by adding the flexibility to adjust the equity modifier to reflect performance and expected contributions, further aligning the interests of our CEO and EVPs with the interests of our shareholders.

The target value, available individual ratings and corresponding performance rating-based equity modifier ranges for our executive officers are set forth in the table below.

    Performance Rating-Based Equity Modifiers
  Target value      Not Building      Building      Strong      Leading      Leading
Exemplary
CEO $13,500,000 —% 50% - 86.5% 86.5% - 113.5% 100% - 127% 113.5% - 127%
COO $4,750,000 —% 50% - 80% 80% - 120% 100% - 150% 120% - 150%
EVP (excluding the COO) $4,000,000 —% 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.

Historically, equity awards were determined by the following formulaic approach for each performance rating.

  Performance Ratings
        Not Building       Building       Strong       Leading       Leading
Exemplary
CEO —% 50% 100% 113.5% 127%
NEOs (excluding the CEO) —% 50% 100% 125% 150%

Based on a comparative analysis of our Peer Group companies, as supplemented to address Mr. Arbuckle’s COO role, the MDCC set a target equity value for Dr. Kewalramani of $13.5 million, and maintained the target equity value for Mr. Arbuckle and our other EVPs of $4.75 million and $4.0 million, respectively. The mid-point of the performance factor range for Leading and highest performance factor for Leading Exemplary performance were selected based on award values approximating the 75th and mid upper quartile percentiles, respectively, of executives at our Peer Group companies. The number of shares granted pursuant to the time-vested RSU award and PSU award was based on the executives' individual rating (i) in 2015 underfair value of our share-based guidelines and (ii) in 2016 under our new value-based guidelines.

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 valueour management team. Our near-term objective of 2016 equity-basedgrowing our CF business through increasing the number of people eligible and able to receive our medicines complements our long-term strategic objectives, which require the reinvestment of revenues into R&D to develop additional transformative medicines for serious diseases.

The final performance multipliers for our 2023 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 200% in February 2024. The following chart shows the pre-established financial goals and the actual results for the financial-based PSU awards granted in 2023:

Consistent with our philosophy of aligning compensation with performance, for 2023, a year in which we substantially exceeded our CF net product revenue expectations, the payout on our one-year financial PSU awards achieved the maximum level.

The performance goals for the 2021 non-financial PSUs were established in February 2021 and our performance against these goals was determined in the first quarter of 2024. There were three non-financial goals and achievement of one goal would have resulted in a 50% payout, achievement of two goals resulted in a 100% payout and achievement of three goals would have resulted in a payout of 200%. While we achieved many significant milestones during this period, in part described above, we did not achieve one of the milestones associated with these PSUs.

The final performance multipliers for our 2021 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 100% in February 2024. Performance achievement for the 2022, 2023 and 2024 non-financial based PSU awards will be determined in the first quarter of 2025, 2026 and 2027, respectively, based on performance over the relevant three-year performance period. The non-financial goals contained in our three-year PSU awards for 2022, 2023 and 2024 are based on our methodology for determining the grant-date fair value, including underlying assumptions for calculating these values as set forth in Note N to our consolidated financial statements included in our 2015 Annual Report on Form 10-Kmultiple clinical milestones, and are subject to adjustment.

In connection withnot disclosed for competitive reasons and because the revision of our equity program, we have eliminated our practice of granting mid-year equity awards. In addition, we do not expect to grant off-cycle equity awards to our named executive officers in 2016. As a result of these changes, the grant date fair-value of our NEOs total equity compensation under the annual program will decrease by 40% to 45% in 2016 under the new value-based program as compared to 2015 under the share-based program. Dr. Altshuler's equity grants in 2015 included his sign-on equity grant.

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 a career employment/retirement provision and participation in our employee stock purchase plan.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, are eligible tomay 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. WeOther than the retirement provision under our equity program available to all employees, we do not provide any other retirement benefits to our executive officers. Under his amended employment agreement, Dr. Leiden receives an annual cash payment intended to facilitate participation in the company’s benefit plans.

VERTEX PHARMACEUTICALS INCORPORATED - 2024 Proxy Statement     70

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 recruited. Accordingly, the initial employment terms for each of the executive officers may vary significantly because they take into account both our interests and the executive’s interests under the circumstances at the time of negotiation, and depend on the level of job responsibility, the market for the executive’s services, the value of other opportunities then available to the executive and similar considerations. Executives who join us from other companies may sacrifice potential bonuses and/or equity payouts, and may request compensation elements of similar value. More experienced individuals may seek higher compensation than individuals who are still establishing their careers. We seek to balance the need to be competitive in a competitive market against the need for the executive’s compensation to be comparable with the executive’s peers at the company.hired. In general, each newly hired executive team member enters into an employment agreement and a change of control agreement and is awarded a stock option grant and a restricted stock grant,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 executivesEVPs 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 of the members ofEVP on our executive team including all of the NEOs, 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 2023, we extended Dr. Leiden’s amended employment agreement by one year, until March 31, 2025. Under his amended employment agreement, Dr. Leiden will not receive any cash compensation for his role as Executive Chairman other than an annual cash payment intended to facilitate participation in the company’s benefit plans, and he will continue to receive equity awards for his fifth year of service as Executive Chairman.

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 his or hertheir 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 that retire. Equity awards granted, including those granted to our NEOs, contain a retirement vesting provision, under which a “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 “qualified” participant is a participant (1) who is at least age 55, (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.

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 theseour agreements with our NEOs is set forth below under the heading Employment Contracts and Change of Control Arrangements.

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 would likecontinue to grant performance-based compensation as important elements of our compensation program to be reasonably costthat align corporate shareholder and tax effective. To the extent consistent with our other goals, we seek to preserve corporate tax deductions, while maintaining the flexibility to approve compensation arrangements that we believe are in the bestcompany interests, of the company and our shareholders. The approach doeseven though these awards may not always result in full tax deductibility.

Compensation Practices

Compensation Practices

Equity Grant Practices
The exercise price for each stock option awarded to our executive officers under our equity compensation program is equal to the fair market value of our common stock on the date of grant, which under our equity plans is the average of the high and low price for our common stock on the date of grant.

Our board of directors generally grants employee options two times per year, on the date of its mid-summerannual equity awards to NEOs at a board meeting usuallyscheduled in July, and on the date of its first meeting of each new year, usually in late January oradvance for early February. Beginning in 2016, our named executive officers will no longer receive mid-year equity grants. Supplemental equity grants, if any, are made at board meetings at the time when the board determines they are appropriate in order to meet the objectives of our compensation program. Board and committee meetings generally are scheduled at least a year in advance, and schedulingScheduling decisions are made without regard to anticipated earnings or other major announcements by the company.

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 options and/or restricted stockequity awards effective on the first day of employment, with the options having an exercise price set at the average of the high and low price for our common stock on the employment start date.employment. The employees’ start dates are scheduled without regard to anticipated earnings or other major announcements by the company.

In the past, the MDCC has recommended that our board of directors make an additional, off-cycle equity award to an executive officer or group of officers in order to achieve one or more of the objectives of our executive compensation program. Supplemental grants have been made on an ad hoc basis, when warranted in the judgment of the MDCC and our board. No such supplemental grants of equity compensation were made during 2015. Our MDCC and board do not currently anticipate making supplemental grants in 2016, but retain the discretion to do so if warranted in their judgment.

Compensation Recoupment (“Clawback”) Policy
Policies

We have adopted a recoupment or claw-backclawback policy providing 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

VERTEX PHARMACEUTICALS INCORPORATED - 2024 Proxy Statement     71

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 reimbursement forrepayment 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 chief executive officer and NEOs and in 2014 adopted stock ownership guidelines for our non-employee directors, as discussed in Non-Employee Director Stock Ownership Guidelineson page 2337 of this proxy statement. The guidelines for our NEOs are set forth in the following table:

Employee
EmployeeMinimum Shareholding Requirement
Chief Executive OfficerCEO6X base salary or 150K shares of our common stock

EVPs4X base salary

Individual holdings, and holdings of immediate family members, of (a) common stock, including(b) unvested restricted stock, (b) restricted stock unitsRSUs, and (c) 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. EachAs of March 18, 2024, each of our NEOs including our chief executive officer, currently satisfiessatisfied the individual holding requirements.

Anti-Hedging and Pledging Policy

COMPENSATION DISCUSSION AND ANALYSIS - DETAILED DISCUSSION AND ANALYSIS (continued)


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.

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 below:

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 development and diversity 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 2023 for 2022 performance are included in 2023 compensation. Also included in 2022 compensation is the grant-date fair value of a one-time equity awards granted in December 2022 to Mr. Arbuckle. The equity awards granted in February 2024 to Dr. Kewalramani, Mr. Wagner, Dr. Altshuler and Mr. Arbuckle for 2023 performance and the equity awards granted in February 2024 to Dr. Leiden pursuant to his employment agreement, in each case that are discussed in the Compensation Discussion and Analysis section above, are not reflected in the Summary Compensation Table above.

Bonus

Pursuant to applicable SEC rules, the annual cash bonuses earned by our named executive officersNEOs are set forthincluded under the caption “Non-Equity Incentive Plan Compensation.” Other bonuses, such as sign-on bonuses, are listed separately under the caption “Bonus.”

Stock Awards and Options Awards
Pursuant to applicable SEC rules the grant-date fair values of the equity awards granted in February 2015 for 2014 performance are included in 2015 compensation. Equity awards granted in February 2016 for 2015 performance pursuant to our revised equity compensation program are not reflected in the Summary Compensation Table above and will be included as 2016 compensation in next year’s proxy statement.

The amounts set forth under the captionscaption “Stock Awards” and “Option Awards” in the table above represent the grant-date fair value of awards granted during the applicable fiscal year. Our methodologyIn general, the equity awards reflected in the Summary Compensation Table for determininga 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 reflected in each executive’s compensation for 2023 in the table above is significantly affected by such executive’s performance during 2022.

The “Stock Awards” for 2023, 2022, and 2021 consist of PSU awards and time-vested RSU awards (or, in the case of Dr. Leiden, fully vested common stock) granted in February of each year. In each of 2023, 2022, and 2021, 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. In 2023, 2022, and 2021, the non-financial PSU awards had grant-date values of 50%, 0% and 50%, of the fair value of the target shares, respectively, in accordance with U.S. GAAP. Additionally, the special, one-time PSU award granted to Mr. Arbuckle in December 2022 had a grant-date value 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 including underlying estimatesof the financial and assumptions for calculating these values, is set forth in Note N to our consolidated financial statementsnon-financial PSU awards had been 200% of the fair value of the target shares, the table above would have included in our 2015 Annual Report on Form 10-K filed with the SEC on February 16, 2016.

The "Stock Awards" for 2015 consist of performance-accelerated restricted stock, or PARS, awards granted in February 2015 and a sign-on equity grant for Dr. Altshuler in February 2015. The "Stock Awards" for 2014 consist of PARS awards granted in February 2014, a sign-on equity grant for Dr. Chodakewitz in January 2014 and one-time performance-contingent retention awards granted in the fourth quarter of 2014 to each of our named executive officers (other than Dr. Altshuler).

To supplement the SEC-required disclosure in the Summary Compensation Table set forth above, we have included the additional table below, which shows “Total Realized Compensation” representing the total compensation realized by each named executive officer in each of the years shown. Total compensation as calculated under SEC rules, as shown in the Summary Compensation Table, includes several items that are driven by accounting assumptions, which are not necessarily reflective of compensation actually realized by the named executive officers in a particular year. The amounts reported in the Total Realized Compensation column differ substantially from the amounts reported in the Total column required under SEC rules and are not a substitute for those Total amounts. Total Realized Compensation represents: (1) Total compensation, as determined under applicable SEC rules, minus (2) the aggregate grant-date fair value of restricted stock awards and stock option awards (as determined under applicable SEC and accounting rules and reflected in the Stock Awards column and Option Awards column), plus (3) the value realized in the applicable year from the vesting of restricted stock and exercises of stock options (calculated in the same manner as for the Option Exercises and Stock Vested for 2015table on page 68 of this proxy statement).

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 named executive officers were eligible for pursuant to our 2015 annual cash bonus program. Actual amounts paid to each of the named executive officers under this program for 2015 performance are set forth in the Summary Compensation Table above.
Sign-on Equity Award. The amounts in the “Estimated Future Payouts Under Equity Incentive Plan Awards” column represent the minimum threshold, target and maximum amounts that Dr. Altshuler is eligible for pursuant to his sign-on equity award granted in February 2015. This award will 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 2015 below.
Restricted Stock Grants. The amounts in the “All Other Stock Awards: Number of Shares of Stock or Units” column represent the number of shares of restricted stock granted to the named executive officers in 2015 pursuant to the annual equity program that was in place in February 2015. The restricted stock awards to these named executive officers were made in February 2015 on account of the executives’ performances in 2014. Each of these restricted stock awards is characterized as a PARS award that is subject to time-based vesting on the fourth anniversary of the grant date, subject to acceleration as described in the footnotes to the table Outstanding Equity Awards at Fiscal Year-End for 2015 below.
Options. In accordance with our stock and option plans, the exercise prices for the stock options granted to our named executive officers during 2015 were equal to the average of the high and the low prices of our common stock on the grantvesting date. As a result, in 2015 the exercise prices of options grantedOptions to our named executive officers were higher than the grant-date closing price for the February 3, 2015 and July 21, 2015 grants. In the future, we expect that options will continue to be granted with exercise prices equal to the average of the high and low pricespurchase common stock are no longer provided as an element of our common stock on the

(1)Unvested stock options are vesting in 16 quarterly installments during the first four years of their ten-year terms. The option expiration dates listed above reflect the final expiration date for each of the listed options. If the named executive officer’s service with us is terminated, the options would expire, subject to certain exceptions, three months after the termination of service.
(2)Dr. Leiden’s options expiring in 2019 and 2020 and on May 31, 2021, which were granted in connection with service as a non-employee director, have ten-year terms and will not expire as a result of a termination of service. Dr. Altshuler’s options expiring in 2022 and 2023 and 2024, which were granted in connection with service as a non-employee director, have ten-year terms and will not expire as a result of a termination of service.
(3)Each of these restricted stock awards is a PARS award, which was subject to time-based vesting on February 5, 2017, the fourth anniversary of grant, subject to acceleration of vesting upon the achievement of specified performance objectives. The vesting accelerated in February 2016 for the shares of each award outstanding as of December 31, 2015 upon reaching $1.0 billion in net product revenues over a one-year period from our cystic fibrosis products.
(4)Each of these restricted stock awards is a PARS award, which is subject to time-based vesting on February 3, 2019, the fourth anniversary of grant, subject to acceleration of vesting upon the achievement of specified performance objectives. The vesting accelerates for the first half of the shares upon (i) U.S net ORKAMBI sales for a 12-month period ending on a calendar quarter is equal to or greater than $1.25 billion or (ii) completion of a clinical trial that establishes a proof-of-concept for a next-generation CFTR corrector. The vesting accelerates for the second half of the shares upon (i) worldwide net ORKAMBI sales, excluding U.S. net ORKAMBI sales, for a 12-month period ending on a calendar quarter that is equal to

Notice of Annual Meeting of Shareholders and 2016 Proxy Statement | 73

COMPENSATION AND EQUITY TABLES (continued)

or greater than $500 million or (ii) completion of a pivotal clinical trial of a non-cystic fibrosis drug candidate that provides sufficient data to support a new drug application.
(5)As disclosed in our 2015 Proxy Statement, these restricted stock awards were granted in the fourth quarter of 2014 or the first quarter of 2015 and will vest only if performance objectives are achieved prior to November 15, 2019. These awards will vest, only if we achieve positive EBITDA for the 12-month period ending September 30, 2017 on the third anniversary of the grant date. Between January 1, 2018 and November 15, 2019, if we achieve positive EBITDA for a 12-month period ending on a calendar quarter, these awards will vest on the day following the applicable earnings release. If the executive is terminated by us without cause prior to the second anniversary of the grant, 10% of the shares subject to the applicable award will vest if the performance condition is ultimately satisfied. If the executive is terminated by us without cause after the second anniversary of the grant date and prior to November 15, 2019, 20% of the shares subject to the applicable award will vest if the performance condition is ultimately satisfied.
(6)This restricted stock award is a PARS award, which was subject to time-based vesting on February 2, 2016, the fourth anniversary of grant, subject to acceleration of vesting upon the achievement of specified performance objectives. The vesting for the shares of each award outstanding as of December 31, 2015 occurred on February 2, 2016.
(7)This restricted stock award vests in one remaining annual installment on September 30, 2016.    
(8)This restricted stock award vests in three remaining annual installments on January 31, 2016, 2017 and 2018.     
(9)In 2014, we implemented a career employment/retirement program applicable to all of our employees 55 years of age or older, which provides that qualified employees who have provided significant service to us, are entitled, subject to certain restrictions including the provision of services during a required transition period, to partial or full acceleration of vesting of certain equity awards upon a termination of employment other than for cause. In addition, if such equity award is an option award it would remain outstanding for its original ten-year term. This program is only applicable to equity awards granted on or after February 5, 2014 and is not applicable to the performance-contingent restricted stock granted to our named executive officers in the fourth quarter of 2014 or first quarter of 2015. For Dr. Leiden's 2014 annual equity awards, upon a termination by us without cause or a termination of his employment for good reason, 18 months of service would be added to his length of service as an employee for purposes of calculating this accelerated vesting.

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 $406.89 per share (the closing price on the last trading day of 2023). The value of any PSUs that have not been certified as to the level of performance by the MDCC as of December 31, 2023 are reported above assuming target performance (100%).

VERTEX PHARMACEUTICALS INCORPORATED - 2024 Proxy Statement     80

the value of each share subject to an option to purchase common stock that would be accelerated or continue to vest in the circumstances described below under Employment Contracts and Change of Control Arrangements equals $125.83per share (the closing price on the last trading day of 2015), minus the exercise price per share;
Back of Contents
the value of each share of restricted stock for which our repurchase right would lapse in the circumstances described below equals $125.83per share (the closing price on the last trading day of 2015);
appropriate provision for the continuation of all then-outstanding options would be made in connection with a change of control;
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;
in addition to the amounts above, if Dr. Leiden, Mr. Arbuckle or Dr. Chodakewitz had been involuntarily terminated by us as of December 31, 2015, then 10% of the 2014 retention awards granted to them would vest on or after October 2017 to the extent the performance condition related to such awards is ultimately satisfied. The value of the shares that could vest pursuant to this provision was $1,572,875 for Dr. Leiden and $943,725 for each of Mr. Arbuckle and Dr. Chodakewitz; and
our board of directors would have assigned the same 2015 individual and company performance ratings on December 31, 2015 as they assigned in the first quarter of 2016.
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.
Our board of directors would have assigned the same 2023 individual and company performance ratings on December 31, 2023 as they assigned in the first quarter of 2024.
PSUs granted to Dr. Leiden in his current role as Executive Chairman are not subject to service-based vesting conditions and will remain eligible to vest following certification of the corresponding performance criteria.
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, 2023.

The actual amounts that the named executive officerscurrent 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 theirthe officers’ base salary, target bonus amounts and actual bonus amounts, and the vesting and grants of additional equity awards.

EMPLOYMENT CONTRACTS AND CHANGE OF CONTROL ARRANGEMENTS


EMPLOYMENT CONTRACTS AND CHANGE OF CONTROL ARRANGEMENTS

Executive Severance Arrangements

We have entered into agreements and maintain plans that will require us to provide to our named executive officersNEOs cash compensation, benefits, and/or acceleration of the vesting of equity awards in the event of termination of employment or service as a director under specified circumstances. The following summary descriptions of such agreements with our named executive officers are qualified by the complete terms and conditions set forth in each of the agreements. 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 a named executive officeran NEO dies while an employee, histheir estate and/or beneficiaries would receive full acceleration of all outstanding stock optionsequity awards, and restricted stock awards.if an NEO’s employment is terminated due to disability, they would receive full acceleration of equity grants made. 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:
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 employment is terminated

B)

Any annual bonus for the year prior to the year in which the termination occurs, if not yet paid

C)

A pro-rated bonus for the year in which the termination occurs based on her target bonus for the year in which the termination occurs

Equity:Outstanding options and RSUs unvested on the termination date would receive partial vesting based on the 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:
A)

299% of the sum of her (i) base salary at the time of termination and (ii) target bonus for the year in which her employment is terminated

B)

A pro-rated bonus for the year in which the termination occurs

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 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.

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 then unvested at the time of termination.

Under Dr. Leiden’s employment agreement a change of control shall be deemed to have occurred if:
any person or group, as such terms are used in Sections 13(d) and 14(d)(2) of the Exchange Act, becomes the beneficial owner, as such term is used in Rule 13d-3 promulgated under the Exchange Act, of securities representing more than 50% of the combined voting power of our outstanding securities, having the right to vote in the election of directors; or

Jeffrey Chodakewitz
Employment Agreement
The terms and conditions of Dr. Chodakewitz's employment are governed by a written employment contract, which was entered into in December 2013. His employment agreement provides that he 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. Chodakewitz has agreed not to engage in specified competitive activities for a period of one year after the termination of his employment with us.
Under his employment agreement, if (i) Dr. Chodakewitz’s employment is terminated without cause or (ii) he terminates his employment with us for good reason within 30 days of the event giving rise to his right to terminate for good reason, subject to notice and cure provisions, he would be entitled to receive:

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 2023, Dr. Kewalramani’s annual total compensation, as reported in the Summary Compensation Table, was $20,594,441 and the median of the annual total compensation of all employees of the company (other than our Chief Executive Officer) was $247,549. The ratio of annual total compensation for Dr. Kewalramani to that of our median employee’s annual total compensation was approximately 83:1.

Due to growth in our employee population, we identified a new median employee using target total annual compensation in 2023. 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, 2023) and includes:

Base salary
Target cash bonus
Severance Payment:The sum of his (i) base salary at the time of termination and (ii) target bonus for the year in which his employment is terminated
Restricted Stock:Full vesting of his initial restricted stock award that vests over the four-year period ending in January 2018
Employee Benefits:Continuation of certain employee benefits for up to 12 monthsTarget long-term equity awards
Under the employment agreement, Dr. Chodakewitz would have the right to terminate his employment for good reason upon the occurrence

The methodology included all 5,294 company employees across 21 countries as of the following events without his consent:

his duties are materially diminished to an extent that results in Dr. Chodakewitz ceasing to beOctober 1, 2023.

This pay ratio is a member of our executive management team;     

his base salary is decreased, unless such reduction is part of an across-the-board proportionate reduction in the salaries of our senior management team; or
the office to which he is assigned is relocated to a place 35 or more miles away and such relocation is not at his request or with his prior agreement (and other than in connection with a change in location of our principal executive offices).
Under the employment agreement, cause means:
Dr. Chodakewitz is convicted of a crime involving moral turpitude;
he commits a material breach of any provision of the agreement not involving the performance or nonperformance of duties; or
in carrying out his duties, Dr. Chodakewitz acts or fails to actreasonable 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 is determined,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.

FREQUENTLY ASKED QUESTIONS REGARDING THE ANNUAL MEETING

What is the Purpose of the Annual Meeting?

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;
To hold an advisory vote on our 2023 named executive officer compensation;
A shareholder proposal regarding special shareholder meeting improvement, if properly presented at the meeting; and
A shareholder proposal regarding a report on racial and gender pay gaps, if properly presented at the meeting.

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?

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, Jonathan Biller, and Joy Liu to serve as proxies at the annual meeting.

What is a Proxy Statement?

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 proxy materials?

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 4, 2024, 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, 2023 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 Stock in Street Name?

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 2016the 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 Many Shares Must be Represented in Order to Hold the Annual Meeting?

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.

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

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, and the two shareholder proposals are considered not 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?

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: Shareholder Proposal Regarding Special Shareholder Meeting Improvement

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 a Report on Racial and Gender Pay Gaps

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?
