LETTER TO SHAREHOLDERS

DEAR FELLOW SHAREHOLDERS,

When we wrote to you this time last year, the novel coronavirus, SARS-CoV-2, had recently been declared a global pandemic. Our team had quickly identified ways Regeneron could help and had already begun isolating novel antibodies to combat the disease, but no one recognized the epic, world-changing challenges COVID-19 and 2020 would bring. The numbers have been sobering – nearly 100 million people infected globally, several million dead, and almost everyone impacted in some significant way. The Regeneron team has been deeply impacted as well, from an early outbreak near our headquarters in Westchester, New York, to the personal loss of loved ones.

Despite this unprecedented public health crisis, 2020 was an inspiring year in many ways, demonstrating the power of science and the resilience of our team. We discovered, developed, and manufactured our novel REGEN-COV™ (casirivimab with imdevimab) antibody cocktail treatment for COVID-19 in record time – just 10 months from program inception through an emergency use authorization (“EUA”) from the U.S. Food and Drug Administration (“FDA”). To date, tens of thousands of patients have received REGEN-COV, and we are now working in partnership with the U.S. government, healthcare providers, and advocacy groups to ensure all appropriate patients can access it.

Unlike vaccines, which trigger the body’s own immune response to protect against infection, REGEN-COV provides virus neutralizing antibodies directly to the patient. In the pivotal Phase 3 treatment trial, REGEN-COV reduced hospitalization or death by 70% in high-risk outpatients and reduced symptom duration. As we do our part to bring this pandemic to an end, we continue to evaluate REGEN-COV in additional patient populations, at lower dose levels, and for prevention purposes. To that end, results from the Phase 3 prevention trial showed that REGEN-COV administered as a subcutaneous injection reduced the risk of symptomatic SARS-CoV-2 infections by 81% among household contacts of infected patients. As of April 2021, more than 25,000 people have participated in clinical trials of REGEN-COV, and we thank all the individuals, investigators, and collaborators.

Our financial position remained strong this year, with top-line growth of 30% and bottom-line growth of 28%1 through an increasingly diversified set of revenue and earnings streams. Total revenues for 2020 increased to $8.5 billion, compared to $6.6 billion for the full year 2019.

EYLEA® (aflibercept) Injection continues to reach more patients in competitive eye disease markets, with its efficacy, safety, and convenience setting a high bar for current and potential future entries. We are confident in the durability and continued growth of this important medicine for years to come. Annual EYLEA global net product sales reached nearly $8 billion in 2020 (net product sales outside the U.S. recorded by our collaborator Bayer), and $4.9 billion in the U.S., still without a single price increase in its history.

Looking to the rest of our growing portfolio, more than 80% of our top-line growth in 2020 came from products and revenues other than EYLEA. Dupixent® (dupilumab) global net product sales in 2020 (recorded by our collaborator Sanofi) were more than $4 billion, reflecting growth of 75% versus 2019. This “pipeline in a product” continues to reach more patients in need with an expanded FDA indication for atopic dermatitis in patients ages 6 to 11 and an FDA acceptance of our supplemental application as an add-on treatment for children aged 6 to 11 years with uncontrolled moderate-to-severe asthma, with even more room to grow as it meets its potential to transform the treatment of certain type 2 inflammatory diseases. We also made Dupixent treatment more convenient with the FDA approval of a single-dose, 300mg pre-filled syringe.

As the foundation of our oncology portfolio, our PD-1 inhibitor Libtayo® (cemiplimab) is achieving significant and steady growth with FDA approvals in two new indications, non-small cell lung cancer and basal cell carcinoma, in early 2021. Global net product sales for Libtayo were $348 million in 2020, representing 80% year-over-year growth. We are making progress in other cancers as well, including in March 2021 when positive results in overall survival prompted us to stop our cervical cancer trial early, with the data forming the basis of upcoming regulatory submissions. With 11 investigational therapeutics in clinic for a wide range of cancers, including eight bispecific antibodies, we continue to diversify our approach to oncology and are positioned to lead the next wave of innovation in immuno-oncology.

1Bottom-line growth represented by non-GAAP net income per share – diluted, which is not a measure calculated in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). See Appendix A for a definition of this measure and a reconciliation of this measure to the most directly comparable GAAP financial measure.

2021 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING

Our COVID-19 program and other important progress this year was made possible by decades of investment in our foundational VelociSuite® antibody discovery and development technologies, as well as in world-class manufacturing enterprise. Thanks to these investments and the hard work of our colleagues, in 2020 and early 2021 we achieved two new FDA-approvals of novel, Regeneron-discovered antibody medicines: the multi-antibody cocktail Inmazeb™ (atoltivimab, maftivimab, and odesivimab-ebgn) for Ebola, and the ANGPTL3 inhibiting antibody Evkeeza™ (evinacumab) for a rare form of inherited high cholesterol.

Regeneron is known for our science-driven approach, and as such our pipeline and research efforts continue to expand. We continue to reinvest a significant portion of our growing revenue into our R&D efforts to fuel the remarkable innovation and curiosity of our world-class team. Our early pipeline is increasingly powered by genetics, thanks to significant insights from the Regeneron Genetics Center®, which reveals new targets for exploration as well as enriching current clinical programs. Our genetics medicine efforts also include important collaborations with Intellia Therapeutics, Inc. and Alnylam Pharmaceuticals, Inc., which pair Regeneron’s biologic and antibody capabilities with cutting-edge technologies like CRISPR gene editing and RNA silencing. Both of these partnerships advanced candidates into clinical development for the first time in the past year.

While 2020 tested us in new ways, we are proud to say that the Regeneron team successfully advanced our mission of using the power of science to bring new medicines to people in need. We came together as never before. Watching our employees rally to support each other was awe-inspiring, as was the strong spirit of collaboration and pride in our collective purpose. We head into this next year with the confidence that we will continue to tackle some of the world’s biggest health and scientific challenges.

Dear Shareholders, 2015 was a busy and rewarding year for Regeneron as we made major strides in advancing our mission of bringing important new medicines to people with serious diseases, over and over again. We delivered EYLEA® (aflibercept) Injection, our therapy for patients with serious vision-threatening diseases, to more and more patients, and we launched PRALUENT® (alirocumab) Injection, a first-in-class therapy for uncontrolled LDL cholesterol in certain patients. Our pipeline of a dozen clinical-stage antibodies continues to progress, with important programs in eye disease, cancer, infectious disease, pain, cardiovascular disease and inflammation. We also continue to invest in technology and innovation that will position us to bring needed new medicines to patients for many years into the future. Likewise, we have made important infrastructure investments to ensure our long-term success, including adding two new buildings at our headquarters in Tarrytown, New York, and expanding our industrial operations facilities in Rensselaer, New York, and Limerick, Ireland. We have always run Regeneron by the principle of “doing well by doing good.” In addition to our work to invent new and needed medicines, we focus on improving our world and operating with the highest standards of integrity. This year, for the first time, our Annual Review integrates reporting on our citizenship priorities and aspirations, in addition to our financial and business performance. We invite you to read more about our business, pipeline and citizenship efforts below, and with supplemental content on our website at investor.regeneron.com/2015AR. Our 2015 Annual Report on Form 10-K is available on the Investor Relations portion of our website. MARKETED MEDICINES EYLEA® (aflibercept) Injection and Retinal Disease Programs Market-leading VEGF-Trap approved in more than 100 countries for the treatment of many blindness-causing retinal conditions, including wet age-related macular degeneration and diabetic macular edema (DME). EYLEA net sales in the U.S. increased 54 percent to $2.676 billion for the full year 2015, from $1.736 billion for the full year 2014. Outside of the U.S., where our collaborator Bayer HealthCare commercializes EYLEA, net sales were $1.413 billion in 2015, compared to $1.039 billion in 2014. Regeneron recognized $467 million from its share of net profit outside the U.S. in 2015, compared to $301 million in 2014. This growth was driven in part by the publication in early 2015 of first-year results from an independent National Institutes of Health (NIH)-sponsored comparative effectiveness study in DME. In the study, at one year, EYLEA demonstrated a significantly greater improvement in mean change in best-corrected visual acuity (BCVA) from baseline compared to ranibizumab and bevacizumab, two other VEGF inhibitors used in retinal disease. The rates of most ocular and systemic adverse events were similar across the three study groups. L-1 SHAREHOLDER LET TER

In 2016, we initiated a Phase 3 study of EYLEA in diabetic retinopathy in patients without DME, a common degenerative eye disease that impacts people with diabetes. We continue to explore EYLEA in combination with other mechanisms, and have two ongoing clinical programs in this area in collaboration with Bayer HealthCare: aflibercept+PDGFR-beta and aflibercept+ANG2. PRALUENT® (alirocumab) Injection Only monoclonal antibody targeting PCSK9 (proprotein convertase subtilisin/kexin type 9) available in two doses, allowing for tailored therapy based on a patient’s LDL-C lowering needs. In July 2015, PRALUENT was approved by the U.S. Food and Drug Administration (FDA) as adjunct to diet and maximally tolerated statin therapy for the treatment of adults with heterozygous familial hypercholesterolemia or clinical atherosclerotic cardiovascular disease who require additional lowering of LDL-C (often referred to as “bad cholesterol”). The effect of PRALUENT on cardiovascular morbidity and mortality has not been determined. Together with our collaborator Sanofi, the U.S. launch is underway. We have focused on physician education about this new class, as well as achieving patient access and reimbursement coverage from health plans. PRALUENT was also approved in the E.U., and launches are underway across the region. The ongoing ODYSSEY OUTCOMES clinical trial program, which is evaluating the potential of PRALUENT to prevent heart attacks, stroke and cardiac death, reached full enrollment in 2015, with more than 18,000 patients at more than 2,000 study centers. Interim results are possible in late 2016, and we expect full results in 2017. L-2

* in collaboration with Sanofi ^ in collaboration with Bayer HealthCare † in collaboration with Mitsubishi Tanabe LATE-STAGE PIPELINE Sarilumab Anti–IL-6 monoclonal antibody under U.S. regulatory review for the treatment of rheumatoid arthritis (RA). In 2015, we reported positive data from three Phase 3 trials of sarilumab in patients with rheumatoid arthritis. Together with our collaborator Sanofi, we submitted the U.S. Biologics License Application in November 2015 and were assigned a Prescription Drug User Fee Act (PDUFA) date of October 30, 2016. In March 2016, the Phase 3 SARIL-RA-MONARCH monotherapy study met its primary endpoint by demonstrating that sarilumab was superior to adalimumab (Humira®) in improving signs and symptoms of active RA at Week 24. The incidence of adverse events, serious adverse events, infections and serious infections was generally similar between groups. Dupilumab First-in-class investigational monoclonal antibody blocking IL-4 and IL-13, two key cytokines believed to be drivers in allergic inflammation, being studied for the treatment of certain allergic conditions, including atopic dermatitis (AD), uncontrolled asthma and eosinophilic esophagitis. Dupilumab was granted a Breakthrough Therapy designation by the FDA for the treatment of adults with moderate-to-severe atopic dermatitis who are not adequately controlled with topical prescription therapy and/or for whom these treatments are not appropriate. We expect to submit an application for FDA approval later this year. In 2016, we reported positive topline results from two large Phase 3 studies in atopic dermatitis and continue to enroll patients in a second pivotal study in asthma. In the atopic dermatitis studies, the overall rate of adverse events was comparable between the dupilumab groups and the placebo groups. REGN2222 Our fully human monoclonal antibody being investigated for the prevention of serious lower respiratory tract infections associated with Respiratory Syncytial Virus (RSV). In 2015, we initiated the Phase 3 NURSERY-Pre-term trial that will evaluate the efficacy, safety, pharmacokinetics and immunogenicity of REGN2222 in infants under the age of six months. Fasinumab Our antibody targeting nerve growth factor being evaluated for potential to offer a novel, non-opioid approach to addressing chronic pain. Two clinical trials of fasinumab for pain due to osteoarthritis and chronic back pain were initiated in 2016. In 2015, we entered into a collaboration with Mitsubishi Tanabe Pharma Corporation to develop and commercialize fasinumab in Japan, Korea, and nine other Asian countries (excluding China). L-4

EARLY-STAGE PIPELINE AND R&D Immuno-oncology Building on our existing antibody collaboration, we launched a new $2.2B global immuno-oncology collaboration with Sanofi. This will provide important new resources to advance our portfolio in this rapidly developing field, which seeks to harness the body’s immune system to fight cancer. We continued to explore multiple approaches in immuno-oncology, including bispecific antibodies, checkpoint inhibitors and antibody drug conjugates. We have two antibodies, a CD20/CD3 bispecific antibody and a PD-1 inhibitor, in clinical studies with data expected in 2016. A number of additional immuno-oncology antibodies are expected to enter the clinic this year and next. Rapid Response & Infectious Disease Regeneron’s Rapid Response capabilities leverage our core VelociSuite® technologies to significantly compress the time required for discovery and preclinical validation of potential treatments for emerging infectious diseases. In 2015, we identified and validated a novel therapeutic cocktail of three antibodies targeting the Ebola virus, and reached an agreement with the Biomedical Advanced Research and Development Authority of the U.S. Department of Health and Human Services to develop, test and manufacture this potential treatment. A Phase 1 study in healthy volunteers is planned for the first half of 2016. We similarly identified and validated an antibody against MERS (Middle East Respiratory Virus) and are working to advance this program, as well as pursuing antibody therapies for other devastating viral diseases such as Zika and Dengue. Regeneron Genetics Center In its second full year, the Regeneron Genetics Center (RGC) continued to grow rapidly in terms of scope, scale and speed. The RGC was created to elucidate, on a large scale, genetic factors that cause or influence a range of human diseases. The team has sequenced approximately 100,000 exomes to date, and is now delivering new target opportunities and validating existing targets in our preclinical and clinical programs. We continued to bring on board world-class collaborators from industry, academia and leading health-systems, and published the RGC’s first peer-reviewed publication in the New England Journal of Medicine. GROWTH In 2015, we grew in many aspects of our business. We continued construction of our world-class 400,000-square-foot manufacturing facility in Raheen, Ireland, which will significantly expand our biologic supply capabilities for commercial products. We opened new L-5 SHAREHOLDER LET TER

buildings in Rensselaer, our Industrial Operations headquarters, and our Tarrytown R&D laboratories and corporate headquarters. And we welcomed our 4,000th Regeneron employee, all while remaining focused on sustaining the innovative culture that makes us unique. SHAREHOLDER ENGAGEMENT One of the priorities of the Board of Directors and Company management is ensuring robust outreach and engagement with our shareholders. We value shareholder views and insights, and we believe that constructive and meaningful dialogue allows us to develop broader relationships with investors over the long-term and builds informed relationships that promote transparency and accountability. In 2015, we continued our shareholder outreach efforts and engaged in discussions with a large number of our shareholders. Please refer to the table on page 53 of our proxy statement for a summary of recent changes we have adopted based on shareholder feedback and other relevant considerations. CITIZENSHIP At Regeneron, we are committed to a better future. In addition to our work to invent new and needed medicines, we are focused on improving our world and operating with the highest standards of integrity. We are proud not only of what we do, but how we do it. Four pillars help us articulate how we view our responsibility and commitment to society: Fostering the Future of Scientific Innovation We believe Science, Technology, Engineering, and Math (STEM) education is a top priority, and are focused on ensuring a strong pipeline of STEM talent for many years to come. Our strategic programs in this area: • Attract, support and reward the best and brightest minds in science research; • Increase the effectiveness of teachers in STEM; and • Bridge STEM skills gaps and career awareness among students historically underrepresented in the sciences. Spanning from elementary school to postdoctoral fellowships, our STEM programs spark interest in science and enhance knowledge, scientific research and careers in biotechnology. One important program allows more than 200 high school and college students to participate in internship opportunities at Regeneron. In addition, we are proud to award the Regeneron Prize for Creative Innovation each year to outstanding graduate and postdoctoral students. Cultivating Sustainable Communities Regeneron employees are passionate about giving back to our communities through volunteerism, fundraising and advocacy. Regeneron In the Community (RIC), our company volunteer program, unites our people through days of service, company-sponsored activities L-6


GRAPHIC

and employee-led projects. RIC inspires action, fosters collaboration and motivates our people to self-organize around service projects that reflect their individual passions. We want to grow our business while reducing our environmental impact. We proactively seek environmentally responsible ways to better operate our business now and in the future, and we focus on environmental stewardship throughout our value chain. Supporting Patient Communities Our employees are focused on putting science, technology and innovation to work in order to make a difference in patients’ lives. This effort starts in the labs, moves into the clinic and continues with our commitment to ensuring patients can access the therapies they need. Nurturing our High-Engagement, High-Integrity Culture We empower our people to thrive personally and professionally, work together to create positive change and promote an ethical culture of diversity and inclusion. In 2015, we were proud to be named one of the two top employers in the global biopharmaceutical industry by Science for the fifth consecutive year, the fourth most innovative company in the world by Forbes and one of the 100 best companies to work for by Fortune. IN CLOSING Unfortunately, there was also some sadness in 2015. Our longtime friend, mentor, co-founder and Board member, Dr. Alfred G. Gilman, passed away in December. Dr. Gilman was a Nobel Laureate who made lasting contributions to science and medicine. On a personal level, we all benefited greatly from Al’s counsel and wry wit over the years, and we will miss him greatly. We look forward to updating you on our progress as we continue building Regeneron into a leading global biopharmaceutical company. Sincerely, P. Roy Vagelos, MD Leonard S.

2015 Performance Overview (see "Executive Compensation – Compensation Discussion and Analysis – Section 1 – Summary – 2014 Performance Overview" on page 35 for more information)

2015 was another extraordinary year for Regeneron. Our key accomplishments in 2015 included:

47% growth in EYLEA® (aflibercept) Injection global net product sales as compared to 2014;
46% growth in our total revenues as compared to 2014;

19% growth in non-GAAP net income as compared to 2014 (non-GAAP net income is not a measure calculated in accordance with U.S. Generally Accepted Accounting Principles; see Appendix A for a definition of non-GAAP net income and a reconciliation of non-GAAP net income to net income);

advances in our EYLEA® franchise, including regulatory approval of EYLEA® for the treatment of visual impairment due to macular edema secondary to retinal vein occlusion and the treatment of visual impairment secondary to myopic choroidal neovascularization in the European Union; regulatory approval of EYLEA® for the treatment of diabetic retinopathy in patients with diabetic macular edema in the United States; and regulatory approval of EYLEA® for the treatment of retinal vein occlusion in Japan;

regulatory approval and launch of Praluent® (alirocumab) Injection, the first drug approved by the U.S. Food and Drug Administration ("FDA") in a new class of drugs that lower LDL ("bad") cholesterol;

positive Phase 3 data for sarilumab from three Phase 3 studies in patients with rheumatoid arthritis (SARIL-RA-TARGET, SARIL-RA-EASY, and SARIL-RA-ASCERTAIN) and submission of a Biologics License Application for sarilumab with the FDA;

positive pivotal Phase 2b data for dupilumab in asthma and completion of enrollment of the dupilumab atopic dermatitis Phase 3 studies;

new collaboration agreement relating to fasinumab with Mitsubishi Tanabe Pharma Corporation for Japan, Korea, and nine other Asian countries, excluding China;

initiation of Phase 3 clinical study of REGN2222 for Respiratory Syncytial Virus;

continued growth of our clinical development pipeline, as evidenced by the submission of one Investigational New Drug Application with the FDA in 2015 and 13 product candidates (consisting of one Trap-based and 12 fully-human monoclonal antibody product candidates based on the Company'sVelocImmune® technology) in clinical development as of December 31, 2015;

new global strategic collaboration with Sanofi to discover, develop, and commercialize antibody-based cancer treatments in the field of immuno-oncology; and

further important steps to support our current and future growth, including adding two new buildings in the Tarrytown campus providing nearly 300,000 square feet of additional laboratory and office space; significant progress with the construction of a new manufacturing facility in Limerick, Ireland; and increasing headcount on a year-over-year basis by approximately 47% as of December 31, 2015.

Our strong performance is reflected in the appreciation of our stock price, which increased 32%, 217%, and 1554% over the one-, three-, and five-year periods ended December 31, 2015, respectively. This shareholder return places our common stock performance in the 85th, 90th, and 99th percentile, respectively, of all NASDAQ-listed companies with a market capitalization greater than $5 billion in those periods.

Executive Compensation (see "Executive Compensation" on page 35 for more information)

We believe that the leadership of the current executive team has been instrumental to our success in 2015 and prior years, and that an executive compensation program that attracts, motivates, and helps retain key executives, including the Named Officers, is critical to our long-term success.

The main objectives of our executive compensation program are to pay for performance; closely align the interests of shareholders and management; strike a balance between short- and long-term perspectives and support our long-term growth prospects; and attract and retain highly skilled and talented executives in a competitive marketplace.information.

These objectives were reflected in our 2015 compensation decisions in a number of ways, including the following:

We believe in performance-based compensation and long-term incentives. In 2015, we continued to rely primarily on performance-based compensation, both for our short-term (cash bonus) and long-term incentives (stock option awards). This emphasis on performance-based compensation (particularly long-term incentives in the form of stock options) has been a consistent part of our philosophy since Regeneron's inception, including prior to the significant appreciation in Regeneron's stock price that began in early 2011.

We believe that time-based stock options are inherently performance based, as they provide value to employees only if there is future stock price appreciation and do not provide any value to employees if the stock price declines below the exercise price. As illustrated by the charts in "Executive Compensation – Compensation Discussion and Analysis – Section 2 – Analysis of 2015 Executive Compensation Based on Compensation Objectives," this emphasis on stock options has resulted in close alignment of our Chief Executive Officer's compensation in 2015 and over the last five years with the performance of our common stock over those periods:

    o
    Both in 2015 and over the five-year period ended December 31, 2015, the year-over-year increases in our Chief Executive Officer's compensation were principally attributable to the significant appreciation in our stock price, which increased the reported grant date fair value of our Chief Executive Officer's stock option awards as determined according to the Black-Scholes model for valuing stock options.

    o
    Over the same periods, the Black-Scholes grant date fair value of stock option grants to our Chief Executive Officer increased less than the appreciation of our stock price, in part because the absolute number of stock options granted to our Chief Executive Officer decreased in the last three years. The number of shares underlying the annual stock option award to our Chief Executive Officer in 2015 was approximately 39% lower than in 2012, while the stock price appreciated 217% over the same period. As a result, the appreciation in the reported value of our Chief Executive Officer's pay was significantly below the appreciation of our stock price, both cumulatively over the five-year period and on a year-over-year basis. This means that the value of our long-term shareholders' investment in Regeneron grew more rapidly than our CEO's pay over those periods.

    o
    To further illustrate this point, over the last five years, our Chief Executive Officer's total direct compensation, as a percentage of Regeneron's capitalization in the year in which the compensation was awarded, decreased from 0.20% to 0.08%.

Proxy Summary


Table of Contents

      o
      As a result of our emphasis on performance-based compensation, on a relative basis when compared to our Peer Group, the total direct compensation of our Chief Executive Officer over the last three years was also closely aligned with the performance of our common stock even when taking into account the reported grant date fair value of our Chief Executive Officer's stock option awards as determined according to the Black-Scholes model.

We believe in year-over-year consistency in making compensation decisions and in striking a balance between the dilutive impact of equity grants and the competitiveness of our compensation program. In our compensation decisions, we focus on the number of shares underlying equity awards relative to the number of basic shares of common stock outstanding, rather than the grant date fair value of the award (as determined according to the Black-Scholes model). We believe this ownership- and dilution-based approach to awarding stock options provides a better measure of the amount of potential increases in shareholder value that would be shared by the awards and allows us to evaluate such grants on a consistent basis as compared to other companies and regardless of fluctuations in the price of Regeneron's or other companies' common stock. Further, focusing on the number of shares and the incremental sharing rate of potential future upside (rather than targeting a specific Black-Scholes grant date fair value) avoids rewarding officers with larger grant sizes following a decline in our stock price.

    o
    As a percentage of the total basic shares outstanding, the 2015 stock option award to our Chief Executive Officer was significantly below the 75th percentile of the companies included in the 2015 Radford Global Life Sciences Survey and only slightly above the 50th percentile (at 0.166% compared to 0.290% and 0.154%, respectively). In addition, this award was below the 50th percentile of our Biotech R&D Peers (which was 0.183%).

    o
    In 2015, the Compensation Committee reduced the number of shares underlying the annual stock option awards to the Named Officers by 15% compared to 2014 (other than

      Mr. Terifay's award, which remained at the 2014 level due to his promotion to Executive Vice President, Commercial). This decrease constituted the third consecutive double-digit percentage decrease in the annual grant of stock options to our Named Officers, in each case following outstanding TSR performance. In reducing the size of 2015 annual stock option awards to executives, the Compensation Committee sought to reduce the potential dilutive impact of new equity awards without adversely affecting the competitiveness of our executive compensation program, which has successfully motivated our senior management team to deliver high operating performance and shareholder value.

      o
      We continued to pay close attention to our burn rate. Despite the expansive growth of our employee base, which increased by 121% between 2012 and 2015 (from 1,950 full-time employees to 4,303 full-time employees), our burn rate decreased from 5.4% to 4.4% over the same period, and we maintained a three-year burn rate average of 4.1% in 2015. We achieved this reduction through implementing three consecutive double-digit percentage decreases in the number of shares underlying annual stock option awards, without eliminating the broad-based nature of our equity compensation program.

      o
      We believe our approach to equity compensation has helped us to successfully grow and manage employee attrition, as evidenced by our 2015 employee turnover of approximately 6%, which compares favorably to the average employee turnover of approximately 18% for the life sciences sector based on the Fourth Quarter 2015 Radford Global Life Sciences Trends Report.

Our Compensation Policies and Practices

We have compensation policies and practices designed to enhance governance of our executive compensation program and to further our compensation objectives. These policies and practices include:

Engagement and use of an independent compensation consultant by the Compensation CommitteeNo "single trigger" change-in-control severance or vesting arrangements for the Named Officers

Stock ownership guidelines for senior executives and directors


Policy against including excise tax gross-up provisions with respect to payments contingent upon a change in control of Regeneron in compensatory arrangements with executive officers, including the Named Officers (other than CEO employment agreement)
Transparent equity granting process and practicesLimited perquisites
Policy regarding recoupment or reduction of incentive compensation that is applicable to officers, including the Named OfficersCompensation Committee and non-employee director oversight of our compensation program
Prohibition against hedging and pledging of our securities by directors and employeesPrudent management of compensation-related risks

OverviewBOARD MEETINGS AND ATTENDANCE OF DIRECTORS

The board held 11 meetings in 2020, of which five were regular and six were special meetings. The Regeneron is committedBoard of Directors Corporate Governance Guidelines provide that directors are expected to good corporate governance, which we believe promotes the long-term interests of shareholders, strengthens the accountabilityattend all or substantially all meetings of the board and the committees on which they serve. All directors attended at least 75% of directors



the total number of meetings of the board and management,committees of the board on which they served, except for Dr. Tessier-Lavigne, who, while attending all of the regularly scheduled board and helps build trustapplicable committee meetings, was unable to attend certain special board meetings called on short notice due in large part to the fact that these meetings had been scheduled without sufficient regard for time zone differences, resulting in his attendance falling below 75% by one meeting. In 2021 to date, Dr. Tessier-Lavigne has attended 100% of the board and applicable committee meetings.

In considering whether to recommend Dr. Tessier-Lavigne for reelection to the board at the 2021 Annual Meeting of Shareholders, the Corporate Governance and Compliance Committee took into account that Dr. Tessier-Lavigne attended all of the regularly scheduled board and applicable committee meetings in 2020 and 100% of the board and applicable committee meetings in 2021 to date; that a number of the 2020 meetings that he was unable to attend were called on short notice, without sufficient regard to the fact that Dr. Tessier-Lavigne was the only director based in the Company. The following chart summarizes key information regardingPacific Time Zone; that appropriate steps had been taken to ensure that all future meetings would be scheduled so as not to disadvantage Dr. Tessier-Lavigne because of his location; and that Dr. Tessier-Lavigne has a long history of good meeting attendance. In light of these factors, the Corporate Governance and Compliance Committee believes that Dr. Tessier-Lavigne’s attendance will not be a future concern and, having taken into consideration his distinguished scientific and academic career and his significant industry experience, recommended to the board that Dr. Tessier-Lavigne should be nominated for reelection to the board.

According to the Regeneron Board of Directors Corporate Governance Guidelines, board members are expected to attend the Company’s Annual Meeting of Shareholders. All of the directors attended our corporate governance.

Board Leadership and Role in Risk OversightBOARD LEADERSHIP AND ROLE IN RISK OVERSIGHT

The board of directors recognizes that one of its key responsibilities is to establish and evaluate an appropriate leadership structure for the board so as to provide effective oversight of management. Since 1995, the board has separated the roles of the Chief Executive Officer and the Chairman of the Board, with Dr. Vagelos serving as Chairman and Dr. Schleifer serving as President and Chief Executive Officer. Dr. Vagelos's extensive leadership experience, his business acumen, and his deep understanding of the healthcare industry have made him an invaluable resource to both the board and Dr. Schleifer. The board has determined that this leadership structure is appropriate for the Company at this time. This determination was based in part on Dr. Vagelos’s extensive leadership experience, business acumen, and deep understanding of the healthcare industry, which the board believes have made Dr. Vagelos an invaluable resource to both the board and Dr. Schleifer.

The board executes its oversight responsibility for risk management directly and through its Committees,committees, as follows:

The Audit Committee oversees the Company's risk management program. The Company's Chief Audit Executive,

    who reports independently to the Committee, facilitates the risk management program. Audit Committee meetings include discussions of specific risk areas throughout the year, as well as annual reports from the Chief Audit Executive on the Company's enterprise risk profile.

The Compensation, Corporate Governance and Compliance, and Technology Committees oversee risks associated with their respective areas of responsibility. As part of its overall review of the Company's compensation policies and practices, the Compensation Committee generally considers the risks associated with these policies and practices. The Corporate Governance and Compliance Committee oversees all aspects of the Company's comprehensive compliance program other than financial compliance and considers legal and regulatory compliance risks. The Technology Committee considers risks associated with our research and development programs.

The board is kept abreast of its Committees' risk oversight and other activities via reports of the Committee chairmen to the full board at regular board meetings. The board considers specific risk topics, including risks associated with our strategic plan, our finances, and our development activities. In addition, the board receives detailed regular reports from members of our senior management that include discussions of the risks and exposures involved in their respective areas of responsibility. Further, the board is routinely informed by the appropriate members of senior management of developments internal and external to the Company that could affect our risk profile.

COMPENSATION OF DIRECTORS

OVERVIEW

Compensation of Directors

Overview

The general philosophy we have applied to compensation of our non-employee directors and the Chairman of the Board is similar to the executive compensation philosophy outlined in the Compensation Discussion and Analysis“Compensation-Related Matters” section of this proxy statement. This philosophy, places anincluding its emphasis on equity compensation, inis consistent with the formCompany’s long-term business orientation and has helped ensure alignment of stock options, which reward growth in stock price and align the directors'directors’ interests with those of our shareholders by providing value to the directors only if there is future stock price appreciation and not rendering any value to the directors if the stock price declines below the applicable exercise price. Similar to executive compensation, the emphasis on long-term incentives in the form of stock options has been a consistent part of Regeneron'sRegeneron shareholders.

Non-employee director compensation philosophy and preceded the significant appreciation in Regeneron's stock price that began in early 2011. As discussed in greater detail below, the board of directors voluntarily reduced the number of shares underlying the three most recentmatters are subject to annual stock option awards to the non-employee directors and the Chairman of the Board by 15% each time, consistent with the reductions in annual awards to executive officers implemented in December 2013, 2014, and 2015.

review. The Corporate Governance and Compliance Committee makes recommendations to the board of directors regarding, and the board of directors determines, the compensation of non-employee directors. The Corporate Governance and

Compliance Committee evaluates the appropriate level and form of compensation for non-employee directors at least annually and recommends changes to such compensation to the board of directors when appropriate. Directors who are Company employees receive no additional compensation for serving on our board of directors or its committees. In determining compensation recommendations for the non-employee directors, the Corporate Governance and Compliance Committee considers, among other things, the qualifications, expertise, and demands on our directors, practices of similar companies in the biotechnology industry (including the Peer Group2), and any recommendationscomparative information provided by Frederic W. Cook & Co. In addition, since November 2018, the Corporate Governance and Compliance Committee has required the annual review of non-employee director compensation by an independent compensation consultant, and has engaged Frederic W. Cook & Co. for this purpose in each of the last three years.

The recent changescurrent compensation program for our non-employee directors and the Chairman of the Board (which has been effective for our non-employee directors and the Chairman of the Board since January 2019 and December 2018, respectively, and is further described below) is referred to in this section as the “Current Compensation Program.”3

NON-EMPLOYEE DIRECTOR COMPENSATION PHILOSOPHY

Our philosophy for non-employee director compensation is simple: to attract the most highly qualified directors with a diverse skillset who will serve as stewards of the Company’s long-term prospects and scientific focus. With this in mind, our non-employee director compensation program described below were adopted based on such considerations.

Cash Feesemphasizes equity compensation primarily in the form of stock options, which reward increases in stock price, over cash fees. The board of directors believes that this emphasis is consistent with the Company’s long-term business orientation and Matching Gifthas helped ensure alignment of directors’ interests with those of Regeneron shareholders. Under the Current Compensation Program,

A we have utilized value-denominated equity compensation awards (granted in the form of stock options and a relatively small percentage of RSUs) for our non-employee directors. This feature of the Current Compensation Program is meant to, among other things, ensure greater stability in reported non-employee director receivescompensation on a year-over-year basis. The board of directors believes that the Current Compensation Program is consistent with Regeneron’s philosophy for non-employee director compensation.

Starting in 2016,2021 through 2023, the board of directors approved an(upon the recommendation of the Corporate Governance and Compliance Committee) determined in November 2020 to increase by 5% the limit on the annual retainer. However, the board did not utilize this limit increase for purposes of setting the 2021 annual retainer of $10,000 for each chairperson of the standing committees of the Company's board of directors, which is in addition to the annual retainer payable to all non-employee directors and the annual retainer payable in respect of service as a director on each standing committee (which remained unchanged). kept it unchanged at $90,000.

Annual Stock Option Awards

Pursuant toCurrent Compensation Program and complied with the terms ofrespective limits imposed by the Second Amended and Restated Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan (as well as its predecessor) and resolutionsthe Settlement.

With respect to each of the Compensation Committee adopted on December 16, 2014January 2020 and December 16, 2015, eachJanuary 2021 annual equity awards, the board of directors (upon the recommendation of the Corporate Governance and Compliance Committee) determined that the targeted aggregate grant date fair value of such equity awards would be set at $600,000 per non-employee director receivesand consist of stock options with a grant date fair value of $480,000 (or 80% thereof) and RSUs with a grant date fair value of $120,000 (or 20% thereof). The January 2020 annual equity awards to our non-employee directors are shown in the table below. On January 4, 2021, each of the then-serving nine non-employee directors received an automaticequity award comprised of stock options representing 3,613 shares of common stock (with a grant date fair value of $480,390) and 248 RSUs (with a grant date fair value of $119,705). The aggregate grant date fair value of the January 2021 equity awards was $600,094 per non-employee director.

Similar to the limit increase described under “Cash Fees and Matching Gift Program” above, the board of directors (upon the recommendation of the Corporate Governance and Compliance Committee) determined in November 2020 to increase by 5% the annual limit on annual equity compensation per non-employee director set forth in the Settlement as permitted under the Settlement in respect of compensation awarded in 2021 through 2023. However, the board of directors did not utilize this limit increase for purposes of the January 2021 annual equity awards to the non-employee directors discussed above.

Similar to the process undertaken in respect of the January 2020 annual equity awards, the Corporate Governance and Compliance Committee recommended the approval of, and the board of directors approved, the terms of the January 2021 annual equity awards (as well as the limit increase discussed above) after consideration of the review, analysis, and recommendations of Frederic W. Cook & Co. Such analysis focused on, among other matters, the market practices of companies in our Peer Group, other relevant industry and market data points, Regeneron’s non-employee director compensation philosophy (including its emphasis on long-term incentives), and the terms of the Settlement.

Under the Current Compensation Program, a pro-rata portion of each equity award (i.e., each stock options become exercisable asoption and RSU award) equal to one-thirdthe portion of one year that has passed from its date of grant vests on the date of the sharesCompany’s first annual shareholder meeting following the date of grant, and the remaining portion vests on the first anniversary of the date of grant in eachgrant. The RSU awards contain mandatory deferral provisions, according to which the shares underlying the RSUs will generally not be delivered to the non-employee director until the earliest of (i) the termination of the three subsequent calendar years,non-employee director’s service as a member of the board, (ii) the seventh anniversary of the RSU grant date, and (iii) the date of a change in control (as defined in the Second Amended and Restated Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan (or its predecessor)). A non-employee director may, subject to compliance with applicable tax rules, elect in writing a maximum deferral period longer than the seventh anniversary of the grant date. Other than as discussed below, the vesting of equity awards is generally subject to continued service on the board, and stock option awards generally expire ten years following the date of grant. In 2015, similar to the reductions in annual awards to executive officers and other employees discussed under "Executive Compensation" below, the Compensation Committee reduced the automatic grant of stock options to our non-employee directors by 15%, from 10,838 shares to 9,212 shares of common stock underlying each such stock option. Similar to the rationale for the reductions in annual awards to executive officers and other employees discussed under "Executive Compensation" below, the impetus for the reductions in the automatic grants to the non-employee directors was to reduce the potential dilutive impact of these grants; the reductions also took into account the increase in the Company stock price since the prior years' awards, with the resulting increases in the grant date fair values of the automatic grants (as determined according to the Black-Scholes model for valuing stock options). The reduced grants to our non-employee directors were made on January 4, 2016. This decrease constituted the third consecutive double-digit percentage decrease in the annual grant of stock options to our non-employee directors, in each case following high stock appreciation, consistent with the reductions in annual awards to executive officers discussed under "Executive Compensation" below.

To the extent they remain unvested and outstanding, stock optionsequity awards granted to a non-employee director continue to vest following the retirement of that director provided applicable conditions relating to the length of the director'sdirector’s service and the director'sdirector’s age have been met. If a non-employee director'sdirector’s service as a member of the board is terminated as a result of his or her death, all of the director's stock optionsdirector’s equity awards will immediately vest in full.

To the extent they remain unvested and outstanding, stock optionsequity awards granted to non-employee directors become fully vested automatically upon a change ofin control of the Company. Each non-employee director has the right to nullify this acceleration of vesting, in whole or in part, if it would cause the director to pay excise taxes under the requirements of the Internal Revenue Code.

It is also designed to incentivize further contributions and ensure Dr. Vagelos's continued service to the Company in the annual stock option awards to our executive officers and the reduction in the annual stock option awards to the non-employee directors made in January 2014, 2015, and 2016. On December 16, 2015, the Compensation Committee granted Dr. Vagelos stock options to purchase 92,123 shares of common stock, at an exercise price of $555.67 per share, the fair market value per share of our common stock on the date of grant (determined as the average of the high and low sales price per share of common stock on the NASDAQ Global Select Market on the date of grant). future.

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth, as of April 14, 2016, the number of shares of the Company's Class Adual-class stock, and common stock beneficially owned by each of the Company's directors, each of the Named Officers referred to below under "Executive Compensation," all directors and executive officers as a group, and each other person or group of persons known by the Company to beneficially own more than 5% of the outstanding shares of common stock or Class A stock, based upon (unless indicated otherwise) information obtained from such persons, and the percentage that such shares represent of the number of outstandingno new shares of Class A stock and common stock, respectively.

The Class A stock is convertible on a share-for-share basis into common stock. The Class A stock is entitled to ten votes per share and the common stock is entitled to one vote per share. We have determined beneficial ownershipbeen issued since our initial public offering in accordance with the rules of the SEC. Except as otherwise indicated in the footnotes below, we believe, based on the information furnished or otherwise available to us, that the persons named in the table below have sole voting1991, and investment power with respect to all shares of Class A stock and common stock shown as beneficially owned by them, subject to applicable community property laws. We have based our calculation of percentage of shares of a class beneficially owned on

1,913,136 shares of Class A stock and 103,165,457 shares of common stock outstanding as of April 14, 2016, except that for each person listed who beneficially owns Class A stock (and for directors and executive officers as a group), the number of shares of common stock beneficially owned by that person (and by directors and executive officers as a group) and the percentage ownership of common stock of such person assume the conversion on April 14, 2016 of all shares of Class A stock listed as beneficially owned by such person (or persons in the case of directors and executive officers as a group) into common stock and also that no other shares of Class A stock beneficially owned by others are so converted.

In computing the number of shares of common stock beneficially owned by a person (and by directors and executive officers as a group) and the percentage ownership of common stock of such person (and by directors and executive officers as a group), shares of common stock subject to options held by that person (and by directors and executive officers as a group) that are exercisable as of April 14, 2016 or are exercisable within sixty days after April 14, 2016 are deemed to be outstanding. Such shares are not deemed to be outstanding, however, for the purpose of computing the percentage ownership of common stock of any other person.

SUCCESSION PLANNING AND TALENT DEVELOPMENT PROCESS

Under our Corporate Governance Guidelines, the board of directors is required to periodically review with our CEO Regeneron’s plan for succession to the offices of the CEO and other senior executive positions.

succession planning and talent review, which includes succession planning for the CEO and other senior management positions and incorporates diversity, equity, and inclusion (“DE&I”) considerations as a strategic priority. From 2018 through 2020, the applicable committees of the board of directors advanced this formal review by focusing on certain assigned functions and roles within the Company. As part of this process, the Audit Committee reviewed functions and roles within the Company’s finance, information technology, and real estate & facilities management organizations, while the Compensation Committee and the Technology Committee reviewed functions and roles within the Company’s commercial and certain other general and administrative organizations and the Company’s research & development and global development organizations, respectively. Implementation of the succession planning and talent review plan has continued in 2021.

In addition to formal succession planning, directors also have exposure to Regeneron leaders through board and committee presentations and discussions and informal events and interactions with key talent throughout the caseyear, both in small-group and one-on-one settings.

CORPORATE RESPONSIBILITY

Regeneron’s mission is to use the power of science to repeatedly bring new medicines to patients. We are committed to operating responsibly, communicating transparently about our impacts, and engaging all stakeholders in our mission. We strive to “Do Well by Doing Good” and have been publicly disclosing information about significant corporate responsibility matters, including by publishing our annual responsibility reports.

Our board of directors and executive officers asmanagement team focus closely on corporate responsibility matters. The charter of the board’s Corporate Governance and Compliance Committee expressly delegates board oversight of corporate responsibility to the Committee. The Company’s policy is to take into consideration the long-term interests of the Company, its shareholders, and other stakeholders, including patients, employees, the healthcare community, regulators, partners, suppliers, and local communities. Under our Corporate Governance Guidelines, the Corporate Governance and Compliance Committee is responsible for overseeing the Company’s key corporate responsibility initiatives, including those expected to have a group).

Our responsibility strategy centers on three focus areas:

Improve the lives of people with serious diseases

2025 GLOBAL RESPONSIBILITY GOALS

In 2020, we made significant progress toward achieving many of these responsibility goals. Select highlights within each focus area are summarized below, and a detailed discussion of our progress in 2020 is included in our 2020 Responsibility Report.

Our responsibility efforts and results across these focus areas have garnered recognitions. For example, in 2020, we were proud to have been included in the Dow Jones Sustainability World Index for the second year in a row and added to the Dow Jones Sustainability North America Index for the first time. These global and regional indices are comprised of corporate leaders in ESG practices.

We also continued to enhance our reporting of these responsibility efforts and results. In 2021, we published on our website our first report on climate-related risks and opportunities, including how we address management and oversight of these risks and opportunities, aligned with the SEC on February 18, 2016.

In 2020, our commitment to improving lives was highlighted as more than three decades of Regeneron scientific and technological expertise culminated in two breakthrough achievements: the approval of Inmazeb by the U.S. Food and Drug Administration (“FDA”) for the treatment of infection caused by Zaire ebolavirus and an FDA Emergency Use Authorization for REGEN-COV™ (casirivimab with imdevimab), our investigational dual antibody cocktail to the SARS-CoV-2 virus. We are proud of these scientific accomplishments and the potentially life-saving benefits they may electcan deliver to vote proportionallypatients. We are dedicated to making sure these new medicines are available to everyone who needs them, including those in low- and middle-income countries.

Since 2018, we have worked with the votes cast by allWorld Health Organization, FDA, and other global organizations to offer Inmazeb under a compassionate use protocol in response to Ebola outbreaks in affected African countries. In 2020, we established an internal access working group and proactively engaged public health agencies, non-governmental agencies, and others in our industry to ensure continued access to Inmazeb in low- and middle-income countries. Similarly, we are collaborating with Roche to increase global supply of REGEN-COV and share a commitment to support access in low- and middle-income countries through drug donations made in partnership with public health organizations.

Foster a culture of integrity and excellence. Regeneron’s unique culture makes us who we are. Our culture includes our science-led mindset, our high ethical standards, and our unbridled focus on solving big, complex problems. As we continue to grow, we remain committed to making significant investments to attract and retain top talent and promote DE&I within our workforce and our community.

CERTAIN RELATIONSHIPS
AND RELATED TRANSACTIONS

Review, Approval, or Ratification of Transactions with Related PersonsREVIEW, APPROVAL, OR RATIFICATION OF TRANSACTIONS WITH RELATED PERSONS

The board of directors has adopted a written policy for the review, approval, or ratification of related person transactions. The Company considers transactions (or a series of related transactions) in which the Company is a participant, the amount involved exceeds $10,000 in any calendar year, and a director, officer, more than 5% holder of our voting securities, any immediate family member of any of the foregoing, or any related entity of any of the foregoing has a direct or indirect material interest to constitute related person transactions. As amended in January 2015, theThe policy provides for a standing pre-approval of transactions with any passive institutional shareholder who holds more than 5% of our voting securities, transactions where all shareholders receive proportional benefits, and certain transactions with Sanofi.Sanofi to the extent such transactions constitute a related person transaction under the policy. With respect to any new transaction that is deemed pre-approved, the Audit Committee receives a summary of each such transaction and retains the ability to require that one or more of such transactions be subject to the standard approval procedures. The policy also requires that the arrangements relating to a permanent, full-time employment of an immediate family member of a director or executive officer hired by the Company be approved in accordance with the policy. In addition, in the event a person is or becomes a director or executive officer of the Company and an immediate family member of such person is a permanent, full-time employee of the Company, no material, outside-of-the-ordinary-course-of-business change in the terms of employment, including compensation, are permitted to be made without the prior approval of the Audit Committee (except, if the immediate family member is himself or herself an executive officer of the Company, any proposed change in the terms of employment are reviewed and approved in the same manner as compensatory arrangements of other executive officers).

The board of directors has determined that the members of the Audit Committee are best suited to review and approve related person transactions. Accordingly, each related person transaction (other than a transaction that is deemed pre-approved as described above) must be reviewed and approved or ratified by the members of the Audit Committee, other than any member of the Audit Committee that has an interest in the transaction. Under the policy, the Chairman of the Audit Committee is delegated the authority to approve certain related person transactions that require urgent review and approval.

When reviewing, approving, or ratifying a related person transaction, the Audit Committee will consider several factors,

including the benefits to the Company, the impact on a director'sdirector’s independence in the event that a director or his/her immediate family is involved in the transaction, the terms of the transaction, and the terms available to unrelated third parties or to employees in general, if applicable. Related person transactions are approved only if the Audit Committee (or the Chairman of the Audit Committee pursuant to delegated authority in the circumstances noted above) determines that they are in, or are not inconsistent with, the best interests of the Company and our shareholders.

In addition, upon Sanofi reaching 20% ownership of our then outstanding shares of Class A stock and common stock (taken together), we were requiredis bound by certain “standstill” provisions under the agreement to appoint an individual agreed upon by us and Sanofi to our board of directors.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth, as of April 13, 2021, the number of shares of the Company’s Class A stock and common stock beneficially owned by each of the Company’s directors, each of the NEOs referred to below under “Compensation-Related Matters—Compensation Discussion and Analysis,” all directors and executive officers as a group, and each other person or group of persons known by the Company to beneficially own more than 5% of the outstanding shares of Class A stock or common stock, based upon (unless indicated otherwise) information obtained from such persons, and the percentage that such shares represent of the number of outstanding shares of Class A stock and common stock, respectively.

The Class A stock is convertible on a share-for-share basis into common stock. The Class A stock is entitled to ten votes per share and the common stock is entitled to one vote per share. No new shares of Class A stock have been issued since our initial public offering in 1991. We have determined beneficial ownership in accordance with the rules of the SEC. Except as otherwise indicated in the footnotes below, we believe, based on the information furnished or otherwise available to us, that the persons named in the table below have sole voting and investment power with respect to all shares of Class A stock and common stock shown as beneficially owned by them, subject to applicable community property laws. We have based our calculation of percentage of shares of a class beneficially owned on 1,848,970 shares of Class A stock and 104,674,240 shares of common stock outstanding as of April 13, 2021, except that for each person listed who beneficially owns Class A stock (and for directors and executive officers as a group), the number of shares of common stock beneficially owned by that person (and by directors and executive officers as a group) and the percentage ownership of common stock of such person assume the conversion on April 13, 2021 of all shares of Class A stock listed as beneficially owned by such person (or persons in the case of directors and executive officers as a group) into common stock and also that no other shares of Class A stock beneficially owned by others are so converted.

In computing the number of shares of common stock beneficially owned by a person (and by directors and executive officers as a group) and the percentage ownership of common stock of such person (and by directors and executive officers as a group), shares of common stock subject to options, PSUs, RSUs, or other convertible securities (if any) held by that person (and by directors and executive officers as a group) that are exercisable or releasable as of April 13, 2021 or are exercisable or releasable within sixty days after April 13, 2021 are deemed to be outstanding. Such shares are not deemed to be outstanding, however, for the purpose of computing the percentage ownership of common stock of any other person.

COMPENSATION-RELATED MATTERS / COMPENSATION DISCUSSION AND ANALYSIS

COMPENSATION PROGRAM OVERVIEW

OUR CORPORATE CULTURE AND PAY PHILOSOPHY

Our corporate culture and pay philosophy are inextricably linked. Regeneron’s culture is defined by loyal and motivated employees with an entrepreneurial spirit who are dedicated to the Company’s mission to use the power of science to invent medicines for people with serious diseases. To deliver on this mission, we manage our business for the long term and pursue our core strategy of creating and advancing a high-quality, internally developed product pipeline. Our employees’ engagement, commitment, and achievements are key drivers of pipeline success and therefore our long-term performance. For Regeneron to succeed, our compensation model must reward long-term, sustainable performance and reinforce a culture where employees are empowered to pursue fulfilling careers and focus on our mission and drug discovery and development. For that reason, a key part of our pay philosophy is to award equity-based pay to all eligible employees to ensure that when we deliver for patients and for shareholders, everyone shares in the upside growth. In each of the last five years, approximately 90% of the employee equity grants were awarded to our employees other than our NEOs,4 which underscores the broad-based nature of our equity program. In addition, we have consistently outperformed the industry in employee retention in recent years, as demonstrated by our employee attrition rate of less than half the industry average in each of the last five years.5

We focus on long-term growth through internal innovation. Our compensation model and broad-based equity program reinforce our company culture and are designed to reward long-term, sustainable performance.


Our corporate culture also is shaped by our commitment to “Doing Well by Doing Good,” which has inspired the Company for over 30 years and is best exemplified in our fight against COVID-19. This commitment, paired with unrelenting focus on science and innovation, is reflected in our 2025 global responsibility goals. In 2020, we took important steps toward achieving these goals, including our goal to increase representation of qualified diverse individuals in leadership and foster inclusion across our organization. See “The Company – Corporate Governance – Corporate Responsibility” for more information.

2020 BUSINESS HIGHLIGHTS

2015 Performance Overview

We are a fully integrated biopharmaceutical company that discovers, invents, develops, manufactures,Despite the impact of the COVID-19 pandemic on the Company and commercializes medicinesour employees, we made significant progress in all key areas of our business in 2020. During this unprecedented public-health crisis, we also rapidly mobilized our significant scientific, development, manufacturing, and operational capabilities to bring REGEN-COV, our investigational dual antibody cocktail to the SARS-CoV-2 virus, to COVID-19 patients 10 months after program inception when we secured an Emergency Use Authorization from the FDA. Last year also was marked by obtaining FDA approval for InmazebTM (atoltivimab, maftivimab, and odesivimab-ebgn) Injection for the treatment of serious medical conditions. We commercialize medicinesinfection caused by Zaire ebolavirus, submitting six marketing applications for eye diseases, high LDL cholesterol,new products or new indications for existing products, and a rare inflammatory condition and haveadvancing nine new product candidates into clinical development. In addition, we grew the top line by 30% and the bottom line by 28%6 with an increasingly diversified set of revenue and earnings streams. Importantly, more than 80% of our top-line growth came from products and revenues other than our flagship product EYLEA® (aflibercept) Injection. We highlight select 2020 accomplishments below and provide a comprehensive overview of our 2020 achievements, as well as the Compensation Committee’s assessment of those achievements, in the subsection “Components of Executive Pay: What We Pay and Why We Pay It — Annual Cash Incentives.”

4Based on both the grant date fair value and the number of underlying shares. For purposes of this calculation, the five-year, front-loaded PSU awards granted to our CEO and CSO in 2020 were annualized.
5For example, our 2020 turnover rate was 5.6% (8.7% including the impact of the commercial organization restructuring relating to Praluent® (alirocumab) and Kevzara® (sarilumab)) compared to an industry average of 21.0%, with turnover in our research and preclinical development organization ranking among the lowest of all employee groups. Industry average is based on data of U.S. life sciences companies reported in Aon’s 2020 Salary Increase and Turnover Study.
6Bottom-line growth represented by non-GAAP net income per share – diluted, which is not a measure calculated in accordance with GAAP. See Appendix A for a definition of this measure and a reconciliation of this measure to the most directly comparable GAAP financial measure.

COMPENSATION-RELATED MATTERS / COMPENSATION DISCUSSION AND ANALYSIS

In 2020, while investing $2.7 billion in research and development and $615 million in capital expenditures, we also allocated $5.7 billion to repurchase 11 million shares through a share repurchase program and a negotiated stock repurchase.

Our stock performed well in 2020, delivering a TSR of 29% and outperforming the S&P 500 Index and our Peer Group. In addition, our stock significantly outperformed each of the benchmarks shown in the chart below over the 10-year period ended December 31, 2020. While we cannot predict or control the performance of our stock price in any particular period, we believe that our Company’s performance is best assessed from a long-term perspective, consistent with the long-term nature of the drug discovery and development in other areascycle. We also believe that if we continue to deliver pipeline, operational, and financial results, the creation of high unmet medical need, including oncology, rheumatoid arthritis, asthma, atopic dermatitis, pain,shareholder value and infectious diseases. For more information aboutstock price appreciation will follow.

2020 COMPENSATION HIGHLIGHTS

Our compensation program continues to evolve as the Company grows, our competition changes, and our business please see Part I, Item and operating environments transform. In 2020, our Compensation Committee took the significant actions summarized below.

1. "Business"Front-Loaded PSU Awards for CEO and Part II, Item 7. "Management'sCSO Replacing Five Years of CEO and CSO Equity Awards.In lieu of five years of annual equity awards, our Compensation Committee granted, and the non-employee members of the board of directors approved, a five-year, front-loaded PSU award to each of our CEO and CSO. The PSUs can be earned upon achievement of ambitious, predetermined cumulative TSR goals over a primary performance period of five years (target TSR of 65.6% over five years, corresponding to a compound annual growth rate (“CAGR”) of 10.6%; and maximum TSR of 140.4%, corresponding to a CAGR of 19.2%). In developing the compensation structure for our CEO and CSO, the board and the Compensation Committee took into account shareholder preference for this type of performance-based award, as discussed further below. The board also recognized the Company’s long track record of success for patients, shareholders, and employees achieved under the leadership of these executives, as well as the board’s confidence in their vision for the Company and in their ability to leverage Regeneron’s technology platforms, product pipeline, and commercialized assets to create long-term shareholder value.

The PSUs are 100% performance-based and are designed to:

further align CEO and CSO interests with those of Regeneron’s long-term shareholders by rewarding top performance and eliminating time-based stock options from their compensation program;
reward exceptional shareholder value creation over the next eight years (i.e., over a five-year performance period and the subsequent three-year mandatory deferral and holding period); and
ensure stability and continuity of leadership to support the achievement of the next phase of Regeneron’s ambitious product, pipeline, and talent development plans.

* TSR data reflect total returns (stock price appreciation and, if applicable, reinvested dividends).


56   /   2021 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING
COMPENSATION-RELATED MATTERS / COMPENSATION DISCUSSION AND ANALYSIS

As shown in the chart below, the PSUs are designed so that nearly all of the incremental value created is delivered to our shareholders.

Shareholder and CEO/CSO Value Creation from PSUs

($ billions)

See “Compensation Discussion and Analysis – Components of Financial ConditionExecutive Pay: What We Pay and ResultsWhy We Pay It –Annual Equity Awards” for more information on these awards.

2Further Reduction of Operations"Burn Rate through Calibration of Equity Award Mix and Grant Size Reductions.In 2020, the Compensation Committee, in part based on shareholder input and feedback, used a mix of stock options and full-value equity awards for NEOs below the CEO/CSO level and for other employees. Such full-value awards consisted of restricted stock awards, or RSAs, and, for employees outside the United States, restricted stock units, or RSUs. For the 2020 annual equity grants, we reduced by approximately 20% the number of stock options granted per recipient and kept RSA/RSU grant date fair value per recipient at 2019 levels, which allowed us to further reduce the Company’s burn rate to 3.3%, the lowest level in the last eight years. These reductions were realized despite our broad-based equity program and an increase in the number of employees by 12% year-over-year, as shown in the chart below. This recalibrated mix of equity awards was designed to better balance incentivization of growth and employee retention. In 2020, we also strategically deployed special RSAs/RSUs, in addition to annual awards, to reward exceptional performance and/or to further promote employee retention. We expect to continue to assess equity award mix in light of our 2015business performance, competitive environment, and other relevant considerations in future years.

Regeneron Stock Utilization vs. Headcount*

*Burn rate calculated by dividing the number of shares subject to equity awards (stock options, RSAs, and RSUs) granted during the year by the basic weighted-average number of shares of common stock and Class A stock outstanding during the year. PSUs are to be reflected in the burn rate calculation for the year in which they are earned and, therefore, do not impact the burn rate shown in the chart. Headcount numbers based on the number of employees as of December 31 of the applicable year.

In 2020, we actively engaged with our shareholders to solicit feedback, engaging in direct one-on-one discussions with shareholders collectively representing over 60% of the submissionshares of one Investigational New Drug Application with the FDA in 2015 and 13 product candidates (consisting of one Trap-based and 12 fully-human monoclonal antibody product candidates based on the Company'sVelocImmune® technology) in clinical developmentcommon stock outstanding as of December 31, 2015.2020 (excluding shares held by our directors and executive officers). Our Compensation Committee Chair led many of these discussions and reported feedback from shareholders to the Compensation Committee and the board of directors. This feedback has resulted in specific changes implemented in 2020, as outlined below.

What We HeardWhat We Have Done
Preference for further pay-for- performance alignment; support for PSUs introduced for CEO and CSO in 2019 but preference for:Replaced five years of CEO and CSO annual equity awards (i.e., until the Company’s regular year-end grant cycle in December 2025) with a single grant of front-loaded PSUs incorporating rigorous absolute TSR performance goals over a five-year performance period
•  Exclusive use of PSUsGranted 100% of CEO and CSO equity awards in the form of PSUs (significant increase compared to 2019, when the CEO/CSO equity mix consisted of 30% PSUs and 70% stock options)
•  More ambitious PSU goalsIncreased target TSR from 61% to 65.6%; increased TSR goal for maximum payout from 101% to 140.4% (in each case compared to the terms of the PSUs granted in 2019)
•  Other PSU design enhancementsEliminated secondary 4-year performance period in favor of a single performance period of five years (with any earned PSUs vesting at the end of such performance period); included a 3-year holding period after vesting
Investor interest in management team stability and long-term value creationIncreased holding/vesting requirements for 2020 CEO and CSO PSUs by incorporating a five-year performance period and a subsequent three-year holding period
Support for broad-based equity program but concern about burn rate and reliance on stock options

•  Decreased by approximately 20% the number of stock options granted per recipient and maintained RSA/RSU grant date fair value per recipient at 2019 levels, thus reducing burn rate to 3.3%, the lowest level in the last eight years

•  Recalibrated equity award mix (stock options and RSAs/RSUs) for NEOs below the CEO/CSO level and other employees to better balance incentivization of growth and employee retention

•  Strategically deployed special RSAs/RSUs to reward exceptional performance and/or to further promote employee retention

These are just the latest examples of how our compensation program has evolved. See the subsection “Compensation Discussion and Analysis – Compensation Processes – Shareholder Input and Outreach” for additional information on changes adopted based on shareholder feedback.

COMPENSATION PROGRAM OBJECTIVES

Our executive compensation program is designed to pay for performance, drive the creation of long-term, sustainable shareholder value, deliver compensation that is competitively positioned amongst our peers, and align with the pursuit and achievement of both our short-term and long-term strategic collaboration with Sanofigoals. Our pay program must attract and retain talented leaders who can innovate and execute. Managing our business for the long term is a core Company belief, as demonstrated by our history of growing through innovation and through a pipeline of internally developed medicines. Further, the compensation program also must support the board’s and management’s broader objectives, such as those relating to discover, develop,research and commercialize antibody-based cancer treatmentsproduct development; commercialization and access; manufacturing operations; and human capital management, including promotion of a diverse and inclusive workplace. We strive to achieve these objectives by considering the following key compensation program tenets when designing and determining appropriate compensation structures.

Drive innovation through ownership culturePrioritize design simplicity and long-term orientation
Our objective is to create and reinforce an ownership culture where employees are empowered to pursue fulfilling careers and focus on our mission and drug discovery and development. We believe a broad-based equity program that incentivizes long-term performance and promotes employee retention is a key ingredient in achieving this culture of ownership and innovation.Tying compensation to long-term, Company-wide success and straightforward Company goals has enabled us to encourage decision-making that we believe is consistent with the long-term sustainability of our Company and our reputation. Our objective is to remain nimble and to have the ability to pivot quickly if needed, without being hindered by overly complex compensation structures.
Provide at-risk, performance-based equity to all employeesAlign with shareholder interests
A key part of our pay philosophy since our inception has been to award equity-based pay to all employees, not just senior executives, to ensure that when we deliver for patients and for shareholders, everyone shares in the potential upside growth. In line with this goal, approximately 90% of the employee equity grants in each of the last five years were awarded to our employees other than our NEOs. We believe this approach represents one of our competitive advantages.Our objective has always been to ensure close alignment with shareholder interests. All of the direct pay of our CEO and CSO, except for base salary, depends on performance and is “at-risk.” For our CEO, at-risk pay comprised 95% of his direct pay in 2020, which is significantly higher than the percentage of at-risk compensation for CEOs in our Peer Group, as shown in the charts below.7 The new equity design used for our CEO and CSO in 2020 further aligns their interests with those of long-term shareholders. More broadly, the long-term nature of our equity program is consistent with the drug discovery and development cycle and, therefore, helps drive the creation of long-term shareholder value.

Regeneron CEO Pay Mix8Peer Group Average CEO Pay Mix8

7We define “direct pay” or “direct compensation” as total compensation as reported in the Summary Compensation Table in the applicable proxy statement, other than the amounts reported as “All other compensation” and (if applicable) amounts reported under “Change in pension value and nonqualified deferred compensation earnings.” Peer Group CEO pay mix based on median for each compensation component using data reported for 2019.
8“At-risk Equity” consists of stock options and any equity awards with performance-based vesting conditions (such as PSUs). For purposes of this chart, we annualized the five-year, front-loaded PSU award to our CEO. “Other Equity” consists of all other equity awards, such as time-based RSAs and RSUs. “At-risk Equity” and “Other Equity” reflect the grant date fair value of such equity awards. “STIP” consists of bonus and/or other applicable compensation provided under short-term, non-equity incentive plans. “At-risk” compensation consists of STIP and At-risk Equity. Total compensation amounts reflect direct compensation (total reported compensation, other than amounts reported as “All other compensation”).

Corporate Performance

As in 2019, the Compensation Committee utilized an enhanced process with greater involvement of all non-employee directors and the Chairman of the Board to review the Company’s performance for purposes of determining the 2020 cash incentive. This process involved an assessment of the Company’s performance in the following three categories to provide greater transparency desired by shareholders for the treatmentCommittee’s decision-making process:

1factors related to our product pipeline and development for both the near- and long-term;
2factors regarding our financial performance and operations; and
3factors related to our talent, culture, and corporate responsibility.

The factors analyzed under category (1) continued to be a key measure for the Compensation Committee’s assessment and calculating the Company performance multiplier. This recognizes the importance of Ebola virus infection.

For each of the factors listed in the table above, the Compensation Committee assessed actual performance for the year. Based on a holistic assessment of these factors within the framework and the relevant categories outlined above, the Compensation Committee set the Company performance multiplier at 2.25 for 2020. In exceeding the range historically used for annual cash incentive awards (0 to 2.0), the Compensation Committee recognized the significant accomplishments in all key areas of Regeneron’s business despite the impact of the COVID-19 pandemic; the Company’s progress with its novel investigational cocktail REGEN-COV achieved in 2020; and the extraordinary efforts and performance of Company employees in 2020.

Individual Performance

The personal performance multiplier may range from 0 to 1.5. For the explanation of individual factors considered in the cash incentive decisions, see the subsection “Compensation Dashboard—Additional Compensation Information—Annual Cash Incentives.”

2020 Earned Cash Incentives

In determining the level of 2020 cash incentives earned, we calculated the NEOs’ respective target cash incentive amounts (which, for our CEO, was set approximately at the median of the Peer Group) and applied the Company performance multiplier based on the Company’s achievement of 2020 objectives; and, for the three NEOs who also have a personal performance component, we applied a personal performance multiplier. For the three NEOs with a personal performance component, the personal performance component had a 40% weighting and the Company performance component had a 60% weighting. In addition, in each case where this calculation would have resulted in an NEO earning a cash incentive in excess of the maximum amount previously allocated to such executive by the Compensation Committee in March 2020 under our Cash Incentive Bonus Plan, the 2020 cash incentive was capped at such maximum amount. See “Compensation Dashboard—Additional Compensation Information—Annual Cash Incentives.”

Based on the achievement of corporate goals (discussed above) and individual goals (discussed in the subsection “Compensation Dashboard—Additional Compensation Information—Annual Cash Incentives”) in the past year, our NEOs earned the followed cash incentives in 2020:

ANNUAL EQUITY AWARDS

Equity grants represent the largest portion of the value awarded annually to our NEOs for compensation purposes. These awards are designed to incentivize delivery of sustainable long-term value, which we believe is created by focusing on the discovery, development, and commercialization of new medicines. Our Compensation Committee utilizes a customized framework for determining the size and mix of the annual equity awards of our NEOs and other executives, which is periodically reassessed in light of our business objectives, feedback from our shareholders, and market practices. This framework and the relevant considerations underlying our equity program are summarized below.

Performance-Based Sizing and Value Delivery

•  In determining the size of equity awards to our NEOs, we take into account:

•  Corporate performance (assessment of Regeneron’s corporate accomplishments, particularly as they relate to our product pipeline); and/or

•  Individual performance (assessment of performance against the corporate goals established byForbes, the board of directors for the CEO and onethe goals established by the Committee and/or the CEO for the other NEOs, as well as an assessment ofFortune Magazine's 100 best places to work.

These and other recent accomplishments have contributed the individual’s importance to the creation of significant valueCompany’s future performance).

•  Both PSUs (used exclusively for our shareholders. The Company's strong performance is reflected in the appreciation of our stock price, which increased 32%, 217%, and 1554% over the one-, three-, and five-year periods ended December 31, 2015, respectively. This shareholder return places our common stock performance in the 85th, 90th, and 99th percentile, respectively, of all NASDAQ-listed companies with a market capitalization greater than $5 billion in those periods. In addition, our common stock was the 3rd, 4th, and top performing stock in our Peer Group, discussed further in this Compensation Discussion and Analysis section, over the one-, three-, and five-year periods ended December 31, 2015. See "Section 3 – Executive Compensation Process and Considerations – Peer Group" for the definition of our Peer Group and our Biotech R&D Peers.

As illustrated by the chart below, our total shareholder return ("TSR") significantly outperformed both the S&P 500 Index and the S&P Biotechnology Select Industry Index over the past five years.

Compensation Objectives and Elements

We believe that the leadership of the current executive team has been instrumentalequity awards to our successCEO and CSO in 20152020) and prior years, and that an executive compensation program that attracts, motivates, and helps retain key executives, including the Named Officers, is critical to our long-term success. Our executive compensation program is designed to achieve four main objectives:

closely align the interestsstock options (the primary component of shareholders and management;
strike a balance between short- and long-term perspectives and support our long-term growth prospects; and

attract and retain highly skilled and talented executives in a competitive marketplace.

To realize these objectives, we utilize five primary compensation elements, which are summarized in the table below and discussed in detail under "Section 4 – Elements of Executive Compensation":

The Compensation Committee considered each of our compensation objectivesother NEOs’ annual equity awards in determining2020) are performance-based:

•  PSUs only vest if the 2015 compensationrelevant performance criteria related to TSR are satisfied. They are designed to reward top performance; reward exceptional long-term shareholder value creation; and ensure stability and continuity of leadership to support the achievement of the next phase of Regeneron’s ambitious product, pipeline, and talent development plans.

•  Stock options only deliver value if we deliver stock price appreciation for shareholders after grant. No amount of time will make a stock option deliver any value unless the company’s stock price increases.

Long-Term Value Creation

•  PSUs incorporate a long-term, five-year performance period. In addition, the PSUs granted in 2020 require a three-year deferral and holding period, thus promoting and rewarding value creation over eight years.

•  Stock option grants have ten-year terms and four-year vesting provisions (generally requiring our employees, including our NEOs, to remain employed for four years in order for all options to vest*) to align with long-term value creation and the development cycle of our executives,products.

•  RSAs/RSUs promote long-term employment:

•  RSAs/RSUs awarded as a component of annual equity awards vest 50% on the second anniversary of the date of grant and 50% on fourth anniversary of the date of grant, which is a more backloaded vesting schedule than is typical in the industry.

•  Special RSAs awarded to our NEOs vest 100% on the fifth anniversary of the date of grant.

Meaningful Holding Requirements

•  PSUs awarded in 2020 require a three-year deferral and holding period following vesting, except in certain limited circumstances.

•  We require NEOs to retain a significant amount of equity within five years of their employment with Regeneron:

•  Our CEO and CSO must own shares with a value at least 6-times their respective base salaries.

•  Our other NEOs must own shares with a value at least 2-times their respective base salaries.

Risk-Mitigating Policies and Practices

•  We have a recoupment (clawback) policy that enables us to reduce or recoup equity and other incentive compensation for compliance violations by NEOs and other covered officers and employees; importantly, the policy covers both financial and non-financial violations.**

•  We prohibit our NEOs from hedging or pledging Regeneron securities they hold.

•  We periodically evaluate each NEO’s grant history and prior grant size amounts, as well as the amount of outstanding unvested and/or vested but unexercised stock options and other equity awards (if applicable) held, including whether such awards are “in-the-money.” These considerations inform future NEO grant sizes and the Named Officers,mix of equity awards utilized.

*In the case of our CEO, this is subject to the terms of his employment agreement. See the subsection “Compensation Dashboard—2020 Compensation Tables—Post-Employment Compensation—Leonard S. Schleifer, M.D., Ph.D. Employment Agreement.” In the case of our CSO, any unvested stock options granted to him in December 2018 and 2019 will continue to vest following his qualified retirement (as defined in the applicable Company policy).
**See the subsection “Compensation Processes—Risk Assessment” below for further information about the recoupment (clawback) policy.

COMPENSATION-RELATED MATTERS / COMPENSATION DISCUSSION AND ANALYSIS

In applying this framework in 2020, the Compensation Committee granted our NEOs the equity awards discussed below.

Named Executive Officer PSUs Annual Stock
Options
 Annual RSAs Special RSAs 
Leonard S. Schleifer, M.D., Ph.D. 248,108 (Target)

Daniel P. Van Plew  19,950 1,930 5,000 
Andrew J. Murphy, Ph.D.  25,000 1,929 8,285 

All of the equity awards granted to the NEOs in 2020 are subject to the Company’s policy regarding recoupment or reduction (clawback) of incentive compensation for compliance violations, including after such awards have been earned/vested and (in the case of the PSUs) after the expiration of the Holding Period (as defined below).

Five-Year, Front-Loaded PSU Awards for CEO and CSO Replacing Five Years of CEO and CSO Equity Awards

In lieu of five years of annual equity awards (i.e., until the Company’s regular year-end grant cycle in December 2025), our CEO and CSO were each granted a five-year, front-loaded PSU award in December 2020. The awards were designed following detailed and extensive analysis conducted by the Compensation Committee’s independent compensation consultant under the Compensation Committee’s direction, considering, among other relevant factors, Regeneron’s business model and strategy, compensation philosophy, and strategic and financial objectives; Regeneron’s TSR performance compared to its peers and the biotechnology and pharmaceutical industries; and compensation practices of other high-growth companies.

In using PSUs for all of the CEO and CSO 2020 equity awards, the Compensation Committee took into account shareholder feedback and shareholder preference for this type of performance-based award. Historically, annual equity awards to Drs. Schleifer and Yancopoulos overwhelmingly consisted of time-based stock options; in contrast, the 2020 awards consist entirely of PSUs.

The PSUs are 100% performance-based and are designed to:

further align CEO and CSO interests with those of Regeneron’s long-term shareholders by rewarding top performance and eliminating time-based stock options from their compensation program;
reward exceptional shareholder value creation over the next eight years (i.e., over the five-year performance period and the subsequent three-year mandatory deferral and holding period); and
ensure stability and continuity of leadership to support the achievement of the next phase of Regeneron’s ambitious product, pipeline, and talent development plans.

In approving the grant, the board also recognized the Company’s long track record of success for patients, shareholders, and employees achieved under the leadership of these executives, as well as the board’s confidence in their vision for the Company and in their ability to leverage Regeneron’s technology platforms, product pipeline, and commercialized assets to create long-term shareholder value.

As a condition to the grant of these awards, it has been agreed that Drs. Schleifer and Yancopoulos will not be entitled to any additional equity or equity-based awards from the Company until the Company’s regular year-end grant cycle in December 2025.

As shown in the chart below, the PSUs are designed so that nearly all of the incremental value created is delivered to our shareholders.

The terms of the PSUs are further described below.

Primary Performance Measure, Performance Period, and Payout Range.The PSUs have a primary performance period of five years from December 31, 2020 (the “Grant Date”). Between 50% and 250% of the target number of PSUs granted to each recipient (248,108 PSUs) may become eligible to vest upon achievement of absolute TSR goals that were derived from five-year CAGRs of 5.6% (threshold) to 19.2% (maximum), as set forth in the schedule below:

1Starting from $478.30 (the most recent closing price of the Company’s common stock at the time of grant) (the “Initial Share Price”); to be adjusted for any dividends or other shareholder distributions paid during the performance period.
2Determined by applying the five-year TSR CAGR goals to the Initial Share Price; to be adjusted for any dividends or other shareholder distributions paid out during the performance period.
3Payouts are expressed as discusseda percentage of the target number of PSUs awarded to each recipient. Payouts for performance between the levels set forth in greater detailthis table are determined by interpolation.

Performance Goal Measurement.The PSUs may be earned at the threshold level beginning March 15, 2021 and may be earned above the threshold level only after the third anniversary of the Grant Date, in each case based on the average closing price of the Company’s common stock over any 20 consecutive trading days. If and to the extent earned, the PSUs vest 100% at the five-year anniversary of the Grant Date, subject to the recipient’s continued service at that time.

Secondary Performance Measure. If no PSUs have been earned during the five-year performance period, then the recipient will have an opportunity to earn a threshold payout at 50% of the target number of PSUs if the Company’s cumulative TSR over such five-year period exceeds, on a relative basis, the cumulative TSR of the Nasdaq Biotech Index (composite return) by at least 200 basis points. The rationale for the minimum payout for exceeding the industry five-year index is that there may be circumstances in which Regeneron outperforms the broader market without reaching the minimum absolute TSR goals, such as in the case of a recession or industry-wide developments outside management’s control.

2021 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING   /   71
COMPENSATION-RELATED MATTERS / COMPENSATION DISCUSSION AND ANALYSIS

Holding Period.Earned PSUs are generally subject to a mandatory deferral and holding period of three years after vesting (the “Holding Period”). Earned and vested PSUs are not forfeited upon termination of the recipient’s service with the Company, but the shares deliverable in respect of the PSUs may not be sold or otherwise transferred during the Holding Period (except as described below). The Holding Period ends early upon the recipient’s death or disability or a change in control involving the Company.

Termination Treatment.The PSUs will continue to be outstanding and may be earned and vest for so long as the recipient serves as an employee or consultant of the Company or a member of the board of directors. The following provisions further apply to the PSUs in the circumstances described below:

Voluntary Termination or Retirement. Upon voluntary termination or retirement from the Company (except where the recipient’s service continues as noted above), any unvested PSUs are forfeited.
Termination without Cause/Departure for eachGood Reason. If the recipient’s employment with the Company is terminated without Cause or the recipient leaves his employment with the Company for a Good Reason (each as defined in or incorporated by reference into the Second Amended and Restated Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan or the applicable PSU award agreement thereunder (filed as exhibits to the 2020 Annual Report)), earnout is measured as of these objectives under "Section 2 – Analysistermination and all PSUs earned as of 2015 Executive Compensation Basedthat date vest and remain subject to the Holding Period. In this circumstance, PSUs not earned as of such termination date have 12 additional months to be earned and, to the extent earned, will vest on Compensation Objectives."the fifth anniversary of the Grant Date or the first anniversary of the termination, whichever comes first (with the Holding Period beginning upon such vesting). Unearned PSUs are forfeited at the end of the 12 months.
Change in Control. In particular:

the case of a change in control, earnout is measured as of the date of the change in control (using the applicable transaction price as the ending stock price), and all PSUs earned as of that date vest with no Holding Period and any unearned PSUs are forfeited immediately.
Death or Disability. In the case of the recipient’s death or disability, the PSUs remain outstanding and may be earned during their term and, to the extent earned, are not subject to the Holding Period.

Annual Stock Option Awards

Stock options represented a significant component and the largest portion of the grant date fair value of the annual equity awards granted to our other NEOs in 2020. Messrs. Landry and Van Plew each received an award of 19,950 stock options in 2020, representing an 18.6% decrease in the number of underlying shares as compared to their 2019 stock option awards; and Dr. Murphy received an award of 25,000 options in 2020, representing a 2% increase in the number of underlying shares as compared to his 2019 stock option award. For Messrs. Landry and Van Plew, this year-over-year decrease resulted from Company-wide decisions to (i) reduce the guidelines for the number of shares underlying the 2020 annual equity awards by 5% year over year for eligible employees and (ii) reduce the proportion of such shares allocated to the stock option component of annual equity awards to eligible employees, which for our other NEOs was reduced from 70% in 2019 to 60% in 2020. The year-over-year increase in Dr. Murphy’s stock option award was in recognition of the outstanding accomplishments of the Company’s research and preclinical development organization in 2020, including the rapid discovery of REGEN-COV, as well as expected future contributions by Dr. Murphy.

The use of stock options for 2020 annual equity awards to our other NEOs was based on our long-held view that stock options are a useful compensation tool when used thoughtfully as part of a well-designed compensation program because they are inherently performance-based, requiring stock price appreciation before there is any real value earned, and simple. No amount of time will make a stock option deliver any value unless the company’s stock price increases. In addition, stock options reward these NEOs for increasing shareholder value over the entire 10-year option term, which we believe is consistent with the drug discovery and development cycle.

All stock options awarded to our NEOs in 2020 have an exercise price of $492.00 per share, the average of the high and low sales price per share of our common stock as quoted on the NASDAQ Global Select Market on the date of grant. All of these grants consist of non-qualified stock options and vest ratably over a period of four years. Except as set forth below in the subsection “Compensation Dashboard—2020 Compensation Tables—Post-Employment Compensation,” stock option vesting ceases, and unvested stock options are forfeited, upon termination of employment.

72   /   2021 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING
COMPENSATION-RELATED MATTERS / COMPENSATION DISCUSSION AND ANALYSIS

Annual RSAs

Similar to 2019, time-based RSAs were used as a component of the annual equity awards for our NEOs other than our CEO and CSO based on the Company-wide decision to utilize a long-term incentive mix of stock options and RSAs/RSUs for these NEOs as well as other employees. For the 2020 annual RSA/RSU awards, the Committee determined generally to keep the grant date fair value per award unchanged from 2019 both for these NEOs and other employees. In recalibrating the equity award mix for the 2020 annual equity awards, the Committee took into account, among other factors, shareholder feedback about the annual rate of equity compensation dilution, retention considerations, and employee input. Based on this methodology, the Committee granted to Messrs. Landry and Van Plew and Dr. Murphy 1,930 RSAs, 1,930 RSAs, and 1,929 RSAs, respectively, in 2020. Each such RSA vests 50% on the second anniversary of the date of grant and 50% on the fourth anniversary of the date of grant, which is a more backloaded vesting schedule than is typical in the industry.

Special RSAs to Certain NEOs

We supplemented our annual equity awards in 2020 with highly targeted grants of time-based RSAs/RSUs to certain key employees (including two of our NEOs) to reward exceptional performance. In line with this approach, Dr. Murphy and Mr. Van Plew received 8,285 special RSAs and 5,000 special RSAs, respectively, in 2020. Each such RSA vests on the fifth anniversary of the date of grant to promote long-term alignment with the interests of our shareholders as well as employee retention.

PERQUISITES AND PERSONAL BENEFITS

Similar to our other employees, our NEOs may participate in Company-wide health, disability, life insurance, and other benefit plans, as well as our 401(k) Savings Plan. See details concerning the 401(k) Savings Plan in the subsection “Compensation Dashboard—Additional Compensation Information—Perquisites and Personal Benefits.” Our NEOs are eligible to receive a limited number of additional perquisites. These include financial and tax planning assistance, which are taxable benefits.

In addition, our CEO is entitled to life insurance, long-term disability, medical malpractice insurance premiums, and additional tax and financial planning services pursuant to his employment agreement. These are described in footnote 5 to the Summary Compensation Table.

Our CEO and CSO are also eligible for various benefits under our Company security policy, which was approved by the board of directors in 2015 for the purpose of ensuring increased efficiencies and providing a more secure environment for these executives. Based on the recommendation of an independent, third-party security study, our security policy and related guidelines require our CEO and CSO (as well as their spouses and children when they accompany them) to use, as much as practicable, Company-provided aircraft for all business and personal air travel. As amended in November 2020 based on a new security study, the security policy also provides for 24/7 personal security services for each of Drs. Schleifer and Yancopoulos.

Additional information regarding perquisites and other personal benefits provided to our NEOs in, or with respect to, 2020 is given in the applicable footnotes to the Summary Compensation Table and in the subsection “Compensation Dashboard—Additional Compensation Information—Perquisites and Personal Benefits.”

POTENTIAL SEVERANCE PAYMENTS

The following points are key to understanding our change-in-control and other severance provisions:

Outstanding equity award agreements (with the exceptions and qualifications described in the subsection “Compensation Dashboard—Additional Compensation Information—Potential Severance Payments”) for all employees other than Dr. Vagelos include a governance best-practice “double trigger” provision for the acceleration of vesting of awards granted thereunder only upon a without-cause termination by the Company within two years of a change in control.

2021 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING   /   73

COMPENSATION-RELATED MATTERS / COMPENSATION DISCUSSION AND ANALYSIS

We have a policy against excise tax gross-up provisions for payments contingent on a change in control of Regeneron in contracts, compensatory plans, and other arrangement with the Company’s officers (including NEOs) with the exception of the CEO under his existing employment agreement or amendments to it.
Regeneron has no pension, deferred compensation, or retirement plans other than our 401(k) Savings Plan described above.

COMPENSATION PROCESSES

COMPENSATION COMMITTEE

The Compensation Committee is responsible for overseeing the Company’s general compensation objectives and programs. The Compensation Committee evaluates the performance of our NEOs and approves their compensation—in the case of the CEO, subject to approval of the non-employee members of the board of directors. The Compensation Committee operates under a written charter adopted by the board of directors and regularly reviews and reassesses the adequacy of its charter. A copy of the current charter is available on our website at www.regeneron.com under the “Corporate Governance” heading on the “Investors & Media” page.

Annual salaries for the following year and year-end cash incentives and equity awards for all employees are determined in December of each year based on Company and individual performance, as well as other factors, which may include compensation trends among our Peer Group and in the biotechnology industry in general. With respect to our CEO, this process is formalized in the Compensation Committee’s charter, which specifies that the Compensation Committee is to annually present the proposed annual compensation of the CEO to the non-employee members of the board of directors for approval. The non-employee directors and the Chairman of the Board are also involved in reviewing the Company’s performance for purposes of setting the annual cash incentive.

We make our annual equity awards on a regular, pre-set schedule. The meetings at which such grants are approved are generally scheduled well in advance of the grant date, without regard to the timing of earnings or other major announcements. We generally grant annual equity awards to eligible employees whose performance is determined to merit an annual grant, including the NEOs, at a meeting held during December.

Pursuant to the terms of the Second Amended and Restated Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan, stock option awards are granted with an exercise price equal to the average of the high and low sales price per share of our common stock as quoted on the NASDAQ Global Select Market on the date of the grant or, if such date is not a trading day, on the last preceding date on which there was a sale of our common stock on the NASDAQ Global Select Market.

We periodically evaluate the personal benefits and perquisites afforded to our NEOs. The Compensation Committee also regularly meets in executive session to discuss any of the matters that fall within its responsibilities.

MANAGEMENT

Members of our senior management play a role in the overall executive compensation process and assess performance of other officers. They also recommend for the Compensation Committee’s approval the salary, cash incentive, and equity grant budgets for non-officers and make specific recommendations for salary increases, cash incentives, and equity grants for other officers. For our NEOs (other than our CEO), recommendations to the Compensation Committee regarding their compensation are made by our CEO, who also evaluates their performance. Our CEO’s performance is evaluated directly by the Compensation Committee based on the Company’s overall corporate performance against annual goals that are approved by the board of directors at the beginning of each year, as discussed above.

COMPENSATION-RELATED MATTERS / COMPENSATION DISCUSSION AND ANALYSIS

SHAREHOLDER INPUT AND OUTREACH

We believe in casting a broad net for information, and think it is very important to reach out to our shareholders for ideas, input, and direct feedback. We do this formally through our triennial say-on-pay votes, as well as through discussions with our shareholders both in connection with our annual shareholder meetings and in the “off-season,” where we discuss compensation, governance, and other issues of importance and interest to our shareholders. In addition, on a more informal basis, we engage with our shareholders through regular investor relations channels, governance engagements, industry conferences, and informal exchanges in other settings.

Say-on-pay vote.Our shareholders are provided with an opportunity to cast a non-binding, advisory vote every three years on our executive compensation program. Our most recent advisory say-on-pay vote was held at our 2020 annual shareholder meeting, at which this advisory proposal was approved by 70.2% of the votes cast. As has been the case with previous say-on-pay votes, management and the Compensation Committee carefully considered the result of this say-on-pay vote and subsequently solicited further feedback from our key shareholders on compensation and governance matters. In the last several years, following our recent advisory say-on-pay votes, we implemented several changes to our executive compensation program and continued the implementation of our existing compensation and governance initiatives. These and other changes implemented in the last five years are summarized in the table below.

Shareholder outreach.In addition to the more formal input of the say-on-pay vote discussed above, we maintain a robust shareholder outreach program (both in connection with our annual shareholder meetings and in the “off-season”) through which we seek input from shareholders and ESG-focused groups regarding our executive compensation and other governance practices, and implement appropriate changes based on this input.

Our annual shareholder outreach program is quite extensive – last year we engaged in direct one-on-one discussions with shareholders collectively representing over 60% of the shares of common stock outstanding as of December 31, 2020 (excluding shares held by our directors and executive officers). We encourage director participation in our outreach, and our Compensation Committee Chair led many of these discussions. Shareholder feedback is discussed with management and, depending on the topic, relayed for consideration to the appropriate committee of the board of directors (typically the Compensation Committee or the Corporate Governance and Compliance Committee), the full board, or both. In recent years, shareholder input resulted in specific changes to our compensation and corporate governance practices and policies, including the changes discussed below.

Our 2020 outreach discussions built on an active outreach program in prior years and focused on, among other matters, (i) equity compensation matters, including investor views on performance-based equity, the appropriate scope of equity compensation programs, and acceptable burn rate and dilution and (ii) the impact of the COVID-19 pandemic on governance policies and procedures and corporate governance best practices. As discussed elsewhere in this CD&A, influenced by shareholder feedback and input from the past several years, in December 2020 we utilized PSUs for 100% of the equity awards for our CEO and CSO and incorporated certain design enhancements as compared to the PSUs granted in 2019. These changes and other changes we have adopted in the last five years demonstrate our continued commitment to good governance and are outlined in the table below.

Changes Adopted Based on Shareholder Feedback (2016–2021)

This emphasis on performance-based compensation (particularly long-term incentivesCSO equity awards in the form of PSUs (significant increase compared to 2019, when the CEO/CSO equity mix consisted of 30% PSUs and 70% stock options) has been a consistent part of our philosophy since Regeneron's inception, including prior

Other PSU designenhancementsEliminated secondary 4-year performance period; included a 3-year holding period

We believe that time-based stock options are inherentlymanagement team stability and long-term value creation
Increased holding/vesting requirements for 2020 CEO and CSO PSUs by incorporating a five-year performance based, as they provide value to employees only if there is future stock price appreciationperiod and do not provide any value to employees if the stock price declines below the exercise price.    As illustrated by the charts in "Section 2 – Analysis of 2015 Executive Compensation Based on Compensation Objectives," this emphasisa subsequent three-year holding period2020
Support for broad-based equity program but concern about burn rate and reliance on stock options has resulted in close alignment of our Chief Executive Officer'sMaintained broad-based equity compensation in 2015 and overstrategy while addressing concerns about the last five years with the performance of our common stock over those periods:

    o
    Both in 2015 and over the five-year period ended December 31, 2015, the year-over-year increases in our Chief Executive Officer's compensation were principally attributable to the significant appreciation in our stock price, which increased the reported grant date fair value of our Chief Executive Officer's stock option awards as determined according to the Black-Scholes model for valuing stock options.

    o
    Over the same periods, the Black-Scholes grant date fair value of stock option grants to our Chief Executive Officer increased less than the appreciation of our stock price, in part because the absolute number of stock options granted to our Chief Executive Officer decreased in the last three years. The number of shares underlying the annual stock option award to our Chief Executive Officer in 2015 was approximately 39% lower than in 2012, while the stock price appreciated 217% over the same period. As a result, the appreciation in the reported value of our Chief Executive Officer's pay was significantly below the appreciation of our stock price, both cumulatively over the five-year period and on a year-over-year basis. This means that the value of our long-term shareholders' investment in Regeneron grew more rapidly than our CEO's pay over those periods.
      o
      To further illustrate this point, over the last five years, our Chief Executive Officer's total direct compensation, as a percentage of Regeneron's capitalization in the year in which the compensation was awarded, decreased from 0.20% to 0.08%.

      o
      As a result of our emphasis on performance-based compensation, on a relative basis when compared to our Peer Group, the total direct compensation of our Chief Executive Officer over the last three years was also closely aligned with the performance of our common stock even when taking into account the reported grant date fair value of our Chief Executive Officer's stock option awards as determined according to the Black-Scholes model.

We believe in year-over-year consistency in making compensation decisions and in striking a balance between the dilutive impact of equity grants and the competitiveness of our compensation program.    In our compensation decisions, we focus on the number of shares underlying equity awards relative to the number of basic shares of common stock outstanding, rather than the grant date fair value of the award (as determined according to the Black-Scholes model). We believe this ownership- and dilution-based approach to awarding stock options provides a better measure of the amount of potential increases in shareholder value that would be shared by the awards and allows us to evaluate such grants on a consistent basis as compared to other companies and regardless of fluctuations in the price of Regeneron's or other companies' common stock. Further, focusing on the number of shares and the incremental sharing rate of potential future upside (rather than targeting a specific Black-Scholes grant date fair value) avoids rewarding officers with larger grant sizes following a decline in our stock price.

    o
    As a percentage of the total basic shares outstanding, the 2015 stock option award to our Chief Executive Officer was significantly below the 75th percentile of the companies included in the 2015 Radford Global Life Sciences Survey and only slightly above the 50th percentile (at 0.166% compared to 0.290% and 0.154%, respectively). In addition, this award was below the 50th percentile of our Biotech R&D Peers (which was 0.183%).

    o
    In 2015, the Compensation Committee reduced the number of shares underlying the annual stock option awards to the Named Officers by 15% compared to 2014 (other than Mr. Terifay's award, which remained at the 2014 level due to his promotion to Executive Vice President, Commercial). This decrease constituted the third consecutive double-digit percentage decrease in the annual grant of stock options to our Named Officers, in each case following outstanding TSR performance. In reducing the size of 2015 annual stock option awards to executives, the Compensation Committee sought to reduce the

38

Table of Contents

        potential dilutive impact of new equity awards without adversely affecting the competitiveness of our executive compensation program, which has successfully motivated our senior management team to deliver high operating performance and shareholder value.

      o
      We continued to pay close attention to our burn rate. Despite the expansive growth of our employee base, which increased by 121% between 2012 and 2015 (from 1,950 full-time employees to 4,303 full-time employees), ourresulting burn rate decreased from 5.4%using a two-part approach:
2016–2020 (equity grant reductions commenced in 2013)
1. Reduce equity award grant guidelines with respect to 4.4% over the same period, and we maintained a three-year burn rate average of 4.1% in 2015. We achieved this reduction through implementing three consecutive double-digit percentage decreases in the number of shares underlying annual equity awards to eligible employees; and
2.  Starting in 2019, recalibrate equity award mix (stock options and RSAs/RSUs) for NEOs below the CEO/CSO level and other employees to better balance incentivization of growth and employee retention.
In 2020, as a result of this approach, we decreased by approximately 20% the number of stock option awards, without eliminatingoptions granted per recipient and maintained RSA/RSU grant date fair value per recipient at 2019 levels, thus reducing burn rate to 3.3%, the broad-based naturelowest level in the last eight years.

oCOMPENSATION-RELATED MATTERS /
We believe our approach to equity compensation has helped us to successfully grow and manage employee attrition, as evidenced by our 2015 employee turnover of approximately 6%, which compares favorably to the average employee turnover of approximately 18% for the life sciences sector based on the Fourth Quarter 2015 Radford Global Life Sciences Trends Report.COMPENSATION DISCUSSION AND ANALYSIS

Highlights of Compensation Policies and Practices

We are committed to maintaining rigorous corporate governance standards, including those related to the oversight of our executive compensation policies and practices. We have compensation policies and practices designed to enhance governance of our executive
Concern about compensation program for non-employee directors and to further our compensation objectives. These policies and practices include:

Description

Independent Compensation ConsultantThe Compensation Committee's consultant, Frederic W. Cook & Co., Inc., is retained directly by the Compensation Committee, performs projects at the Compensation Committee's direction, and does not otherwise perform any other consulting or other services for us.

Stock Ownership Guidelines


To further align the interests of senior management with the interests of shareholders and promote a long-term perspective, our directors and senior officers are subject to stock ownership guidelines with the following share ownership targets:

Chairman of the Board and Chief Executive Officer, six times (6x) base salary;

Chief Scientific Officer, three times (3x) base salary;

Executive/Senior Vice Presidents, two times (2x) base salary; and

Non-employee members of the board of directors, six times (6x) the annual retainer.

All of our directors and senior officers subject to the stock ownership guidelines have either met their respective share ownership targets or are still within the five-year period for achieving compliance.


Transparent Equity Granting Process and Practices


Annual stock option awards to eligible employees are made by the Compensation Committee according to a regular, pre-set schedule. The meetings at which such grants are approved are generally scheduled about a year in advance, without regard to the timing of earnings or other major announcements.

Recoupment Policy


We have a policy regarding recoupment or reduction of incentive compensation for compliance violations that is applicable to our officers, including the Named Officers, and other specified employees.

Prohibition Against Hedging and Pledging of Our Securities


We have a policy against hedging and pledging of our securities by our directors and employees, including the Named Officers.

No "Single Trigger" Severance or Vesting Change-in-Control Arrangements for Named Officers


Our change in control severance plan, equity award agreements with the Named Officers, and employment agreement with our Chief Executive Officer do not contain "single trigger" provisions (i.e., do not provide for cash severance payments or accelerated vesting of equity awards solely on account of a change in control without a termination of employment).

Policy Regarding Excise Tax Gross-Ups


We have a policy against including excise tax gross-up provisions with respect to payments contingent upon a change in control of Regeneron in contracts, compensatory plans, or other arrangements with the Company's executive officers, including the Named Officers (other than the existing employment agreement with our Chief Executive Officer or any amendments thereto, which we expressly exempted).
Limited PerquisitesThe perquisites and other personal benefits afforded to our Named Officers are limited and are subject to periodic review by the Compensation Committee.
Compensation Committee Oversight; Executive SessionsOur Compensation Committee regularly meets in executive sessions without members of management present.
Risk ManagementOur Compensation Committee regularly reviews our compensation strategy and practices, including an annual review of our compensation-related risk profile, to ensure that our compensation-related risks are not reasonably likely to have a material adverse effect on the Company.

Section 2 – Analysis of 2015 Executive Compensation Based on Compensation Objectives

Pay for Performance

We believe in rewarding performance and establishing a strong link between compensation and both individual and corporate performance at all levels of the Company. We also believe that accountabilityBoard

Introduced a new compensation program for our non-employee directors and total compensation potential should generally increase with position and responsibility and that the proportionChairman of the performance-based component of compensation should increase with position and responsibility. Consistent with this view, individuals with greater responsibility and ability to influence our achievement of corporate goals and strategic initiatives generally are targeted with higher levels of cash compensation, but haveBoard in November 2018. As a higher proportion of their total cash compensation representedresult:2018
  Reduced by cash bonus, the amount of which is based on individual and/or corporate performance and is, therefore, at risk. Similarly, equity-based compensation is higher for persons with higher levels of responsibility, making a significant portion of their total compensation dependent on long-term stock appreciation and, therefore, long-term corporate performance.

This pay-for-performance philosophy was strongly reflected in the mix of compensation elements, or "pay mix," of our Named Officers in 2015. The following charts display the mix of 2015 compensation (fixed vs. performance-based and long-term vs. short-term) of our Chief Executive Officer and our other Named Officers (excluding our Chief Executive Officer) and the mix of compensation elements of the companies included in the 2015 Radford Global Life Sciences Survey. As shown in these charts, 97% and 96% of the total direct 2015 compensation of our Chief Executive Officer and our other Named Officers, respectively, consisted of performance-based compensation, which exceeds the average percentage of performance-based compensation paid by the companies included in the 2015 Radford Global Life Sciences Survey by 7% and 14%, respectively. Accordingly, based on these metrics, our 2015 executive compensation program was more heavily weighted toward "at risk," performance-based components.

COMPENSATION-RELATED MATTERS / COMPENSATION DISCUSSION AND ANALYSIS

INDEPENDENT COMPENSATION CONSULTANT

The Compensation Committee has the sole authority to retain, at the Company’s expense, one or more third-party compensation consultants to assist the Compensation Committee in performing its responsibilities and to terminate the services of the consultant if the Compensation Committee deems it appropriate. In 2020, the Compensation Committee (and, as discussed above with respect to non-employee director compensation matters, the Corporate Governance and Compliance Committee) utilized the services of Frederic W. Cook & Co. In order to maintain its independence, the Compensation Committee retained Frederic W. Cook & Co. directly and Frederic W. Cook & Co. performed services for the Compensation Committee exclusively at the Compensation Committee’s direction. The Compensation Committee periodically evaluates the independence of its compensation consultant. In accordance with applicable listing standards of the NASDAQ Stock Market LLC and SEC rules, in 2020 the Compensation Committee evaluated the independence of Frederic W. Cook & Co.; and, on the basis of this evaluation, concluded that the engagement of Frederic W. Cook & Co. did not raise any conflicts of interest.

The Compensation Committee’s consultant reviews management recommendations for compensation plans, budgets, and strategies, and also advises the Compensation Committee on how regulations and trends in executive compensation nationally and specifically in the pharmaceutical and biopharmaceutical industries may be relevant to the Company. It also assists with developing the Peer Group; provides comparative compensation information for our CEO and CSO and the other members of the board of directors (using the Peer Group and other compensation data as described below); reviews senior management’s compensation recommendations for other officers, including the other NEOs; and provides general advice to the Compensation Committee on compensation matters, including facilitating the articulation and periodic review of the Company’s compensation philosophy or replenishment of our long-term equity incentive plan. In 2020, the Compensation Committee’s consultant also conducted a detailed and extensive analysis under the Compensation Committee’s direction with respect to the five-year, front-loaded PSU award for our CEO and CSO.

PEER DATA

For purposes of setting our NEOs’ and other senior executives’ compensation, we use comparative compensation information from a relevant peer group of companies (referred to in this proxy statement as “Peer Group”). We select the companies in the Peer Group with the assistance of Frederic W. Cook & Co. based on factors including, but not limited to, the following:

research and development orientation;stage of development; and
market capitalization;total revenues.
number of employees;

2021 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING   /   79
COMPENSATION-RELATED MATTERS / COMPENSATION DISCUSSION AND ANALYSIS

The Peer Group is also meant to provide a representative sample of companies with which we compete for talent. We periodically reassess the composition of the Peer Group and make changes as appropriate, taking into account factors such as changes in the Company’s market capitalization and merger-and-acquisition activity impacting the existing Peer Group companies.

The Peer Group utilized in 2020 consists of the following 13 companies:

AbbVie Inc.BioMarin Pharmaceutical Inc.*Incyte Corporation*
Alexion Pharmaceuticals, Inc.*Bristol-Myers Squibb CompanyMerck & Co., Inc.
Alnylam Pharmaceuticals, Inc.*Eli Lilly and CompanySeagen Inc.*
Amgen Inc.Gilead Sciences, Inc.*Vertex Pharmaceuticals, Inc.*
Biogen Inc.*

* Regeneron’s Biotech R&D Peer.

The Compensation Committee reviewed the Peer Group in June 2020 and, based on the recommendation of Frederic W. Cook & Co., made the following changes: (i) eliminated Celgene Corporation due to its acquisition by Bristol-Myers Squibb Company completed in November 2019; (ii) eliminated Alkermes plc and United Therapeutics Corporation due to their respective market capitalizations being significantly below the Company’s; and (iii) added Merck & Co., Inc. and Seagen Inc. (formerly Seattle Genetics, Inc.) due to a number of factors, including their respective business models and the scope of their operations in relation to the Company. As part of its assessment, the Compensation Committee took into account that Regeneron was the median company (or just below the median) in the Peer Group based on market capitalization, the then-available consensus revenue estimates for 2020, and the then-available reported number of employees, based on the data provided to the Committee, as shown in the table below.

COMPENSATION-RELATED MATTERS / COMPENSATION DISCUSSION AND ANALYSIS

Further, in our review of the Peer Group data, we also consider the practices of the eight-company sub-group of peers viewed as having businesses and drug discovery and development cultures that are most similar to Regeneron’s, with similarly-sized employee bases (marked with an asterisk in the table above and referred to as “Biotech R&D Peers”).

In making the compensation decisions in December 2020, we used data from publicly filed proxy statements of the companies in the Peer Group (as compiled by the Compensation Committee’s compensation consultant) to review each component of compensation of our NEOs against their peers in the Peer Group as well as their total annual compensation in relation to the Peer Group, while taking into account various factors such as the executive’s performance, past compensation history, experience, and their role in the Company’s success. We use Peer Group data as a point of reference for measurement, but Peer Group data do not represent the only factor considered and there is no targeted pay level percentile. The Compensation Committee retains discretion in determining the nature and extent of the use of Peer Group data.

RISK ASSESSMENT

We believe that the Company’s programs balance risk and potential reward in a manner that is appropriate to the Company’s circumstances and in the best interests of the Company’s shareholders over the long term. We also believe that the Company’s compensation and benefits programs do not create risks that are reasonably likely to have a material adverse effect on the Company. We regularly review the Company’s compensation and benefits programs, including its executive compensation program and its incentive-based compensation programs (such as sales incentive plans).

The Company’s compensation and governance-related policies are further enhanced by our stock ownership guidelines applicable to our senior officers and our policy regarding recoupment or reduction (clawback) of incentive compensation of our officers and other specified employees for compliance violations. Our policy regarding recoupment or reduction (clawback) of incentive compensation for compliance violations applies to bonus and other incentive compensation, regardless of whether paid or payable in cash, equity, or otherwise and regardless of whether such compensation has been earned or vested. In addition, the policy covers both financial and non-financial violations resulting in a significant harm to the Company’s business, prospects, results of operations, or financial condition. Under the policy, the board and any designed committee of the board have full discretion to make recoupment and reduction decisions as they may deem appropriate subject to applicable law, the Company’s compensation plans in effect from time to time, and all relevant contractual obligations.

We also have policies against hedging and pledging of our securities by our directors and employees, including the NEOs; and against including excise tax gross-up provisions with respect to payments contingent upon a change in control of Regeneron in contracts, compensatory plans, or other arrangements with the Company’s executive officers, including the NEOs (other than the existing employment agreement with our CEO or any amendments thereto, which we expressly exempted).

These policies demonstrate Regeneron’s continued commitment to robust corporate governance and are meant to reduce compensation-related risks and ensure greater alignment of the interests of our employees, including the NEOs, and those of the Company and our shareholders.

TAX IMPLICATIONS

We take tax considerations into account in making our compensation-related assessments and decisions.

Prior to the enactment of the Tax Cuts and Jobs Act in December 2017, Section 162(m) of the Internal Revenue Code generally limited the deductibility for federal income tax purposes of compensation in any year paid to the CEO and the other NEOs (other than the Chief Financial Officer) (the “covered employees”) to the extent such compensation exceeded $1 million, subject to certain exceptions. “Performance-based” compensation, as defined under Section 162(m) of the Internal Revenue Code, was exempt from such deduction limitation if specified requirements set forth in the Internal Revenue Code and applicable Treasury regulations were met. The Regeneron Pharmaceuticals, Inc. Cash Incentive Bonus Plan, adopted prior to the enactment of the Tax Cuts and Jobs Act, allows (but does not require) awards thereunder to be subject to the attainment of performance goals in order to qualify for this performance-based compensation exception.

2021 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING   /   81

COMPENSATION-RELATED MATTERS / COMPENSATION DISCUSSION AND ANALYSIS

Under the Tax Cuts and Jobs Act, which generally became effective for us commencing with our 2018 fiscal year, the exception under Section 162(m) for performance-based compensation is no longer generally available, subject to transition relief for certain grandfathered arrangements in effect as of November 2, 2017. Further, the definition of covered employees has been expanded to include our CFO. In addition, once one of our NEOs is considered a covered employee subject to the deduction limitation of Section 162(m), the NEO will remain a covered employee so long as he or she receives compensation from us. Despite the elimination of the performance-based compensation exception, we have continued to use the Cash Incentive Bonus Plan for annual cash incentives of the NEOs because we believe it furthers our compensation philosophy and objectives regardless of tax treatment. The Compensation Committee will continue to review the full impact of Section 162(m) (as revised by the Tax Cuts and Jobs Act) on the Company, our compensation programs, and executive compensation trends generally as it makes compensation-related assessments and decisions in the future.

Due to the requirements set forth in Section 274(e)(2) of the Internal Revenue Code, Company-provided personal and guest air travel (which is provided by the Company only to the extent permitted under board-approved guidelines and a security policy adopted by the board based on an independent, third-party security study) results in a partial disallowance of the related corporate tax deductions. In 2020, this disallowance amounted to approximately $2.0 million.

We take into account the deductibility of compensation in determining NEOs’ compensation. However, we reserve the right to use our judgment to authorize compensation payments that are not deductible, such as when we believe that such payments are necessary to maintain the flexibility needed to attract talent, promote executive retention, reward performance, or attain other Company objectives, or as required to comply with the Company’s contractual commitments.

This resulted in the charts above) consists of base salary and bonus/STIP. "Performance-based" compensation (shown as part of the outer circleeach NEO receiving one additional paycheck in the charts above) consists of bonus/STIP and equity. Total compensation amounts reflect total direct compensation (total reported compensation, other than amounts reported under "All other compensation").

As shown in the charts above, the Compensation Committee manages the pay mix such that a substantial portion of pay is dedicated to "at risk," performance-based compensation, with that portion to comprise a significantly greater percentage of total direct compensation as compared to the average of the

companies included in the 2015 Radford Global Sciences Survey. The Compensation Committee believes that this mix of pay best aligns the interests of our Named Officers with those of our shareholders over time.

Shareholder Alignment

We believe that the compensation realized by our leadership team, including the Named Officers, should show a strong relation to the value realized by our shareholders. This principle is reflected both in the pay mix referenced above and in our focus on stock options, as the value realized by the holder of a stock option, if any, is dependent upon, and directly proportionate to, appreciation in the price of our common stock. Since our inception, we have consistently structured our executive compensation2020 based on our belief that stock options naturally align executives with the creation of future shareholder value. We also believe that stock options have been fundamental to our ability to attract, motivate, and retain top talent whose contributions and leadership have driven the Company's achievement of corporate and strategic goals and resultedbase salaries then in a substantial enhancement of shareholder value. Over the one-, three-, and five-year periods ended December 31, 2015, our stock price increased 32%, 217%, and 1554%, respectively. This shareholder return places our common stock performance in the 85th, 90th, and 99th percentile,

respectively, of all NASDAQ-listed companies with a market capitalization greater than $5 billion in those periods. Our use of stock options ensures alignment of the interests of our executives, including the Named Officers, with those of Company shareholders, as our executives not only benefit from our successes, and the resulting appreciation of our stock, but are also impacted by decreases in our stock price.

The following chart compares our TSR over the last five years with the compensation of our Chief Executive Officer over the same period. We do not focus primarily on total direct compensation as a key metric, as it is derived in part from the reported grant date fair value of stock option awards as determined according to the Black-Scholes model. As further discussed below, in assessing stock option awards, we primarily consider the number of shares underlying the awards relative to the number of basic shares of common stock outstanding in order to evaluate such awards on a consistent basis as compared to other companies and regardless of fluctuations in the price of Regeneron's or other companies' common stock.

Executive Compensation


Table of Contents

As shown in the table above, compensation awarded to our Chief Executive Officer over the last five years closely tracked our TSR over the same period, and percentage increases in such compensation were considerably smaller than our TSR over the same period (533% increase in total direct compensation compared to 1554% TSR). The overwhelming portion of the increase in our Chief Executive Officer's total direct compensation over this period is directly attributable to the value of the non-cash components of his compensation package, primarily stock option awards valued according to the

Black-Scholes model. Consistent with our objective to align the interests of our executives with the interests of our shareholders, as the price of our common stock appreciated over the last five years, the value of stock option awards, the most significant component of the compensation of our Chief Executive Officer (as well as the other Named Officers), increased as well.

In addition, on a year-over-year basis, percentage increases in our Chief Executive Officer's total direct compensation in the last five years were significantly below the year-over-year appreciation of our stock price,effect, as shown in the chart below.

Balance between Short- and Long-Term Perspectives

The Company's compensation program has been designed to strike a balance between short- and long-term compensation in light of the Company's available resources; its growth trajectory; its goal of offering compensation packages that are competitive with those of companies in the Peer Group and the broader biopharmaceutical industry; and its objective to

retain and motivate high-performing employees and closely align their interests with the interests of shareholders. We utilize base salary and annual cash bonuses to compensate our executives over the short term by providing a base level of income and rewarding performance on an annual basis, and we utilize stock options to foster a long-term perspective and reward long-term performance.

Why stock options?





Time-based stock options represent the foundation of our compensation philosophy and an integral part of our executive compensation program. Since our inception, we have consistently structured our executive compensation based on our belief that stock options naturally align executives with the creation of future shareholder value and are the best vehicle to retain and foster the entrepreneurial aspects of our culture. The core group of our senior management (Drs. Schleifer, Yancopoulos, and Stahl) has been with Regeneron for over 20 years and has been instrumental in driving shareholder value over this period. We discussed our use of time-based stock options as a critical component of our compensation program as part of our 2015 shareholder outreach (discussed in greater detail below) and were again encouraged by the fact that a number of our key shareholders were supportive of time-based stock options and viewed them as an excellent compensation tool for a high-performing, growth-oriented company.

In 2015, as in other recent years, we relied on time-based stock options as the primary vehicle for offering long-term incentives to our employees, including the Named Officers, and for linking compensation and performance. However, we reduced the number of shares underlying the annual stock option awards to the Named Officers by 15% compared to 2014 (other than Mr. Terifay's award, which remained at the 2014 level due to his promotion to Executive Vice President, Commercial). This reduction constituted the third consecutive double-digit percentage decrease in such annual grant.

We believe that time-based stock options are inherently performance-based, offer an excellent compensation mechanism for getting our management team to act in ways that ensure the long-term success of Regeneron, and are appropriate and advantageous for the following additional reasons:

The executive only realizes value from stock options if the price of the Company's common stock increases and the executive continues to serve through the vesting period. The value is solely tied to an increase in the Company's stock price, aligning the interests of executives with those of shareholders.


The executive has the opportunity to realize value if the price of the Company's common stock continues to increase over the remainder of the ten-year term of the option. Time-based options, therefore, promote the long view and motivate and reward the executive for Company performance not only over the four-year vesting term, but also the ten-year option term.

Compared to full-value awards, stock options provide for greater leverage and, therefore, alignment of employee incentives with those of our shareholders. They also amplify downside risk, as they do not provide any value to the holder if the stock price declines below the exercise price (determined as of the date of grant).

Stock options have played an important role in our success and have helped us to conserve the Company's cash.

Stock options are highly valued by employees, particularly in our industry. They have helped us attract and retain entrepreneurial employees and foster an ownership culture, which we believe has been part of the Company's formula for success.

Time-based stock options are understood by employees and are straightforward to administer. We also believe that they are less likely to cause employees to pursue attainment of a particular performance metric at the expense of value creation for our shareholders generally.

Stock options generally qualify as performance-based compensation for purposes of the deduction limit of Section 162(m) of the Internal Revenue Code, and all amounts realized by our Named Officers upon exercise of their stock options are expected to be fully deductible by us.

Executive Compensation


Table of Contents

As shown in the charts under "– Pay for Performance" above, 91% of the total direct compensation of our Chief Executive Officer and our other Named Officers in 2015 consisted of long-term compensation, which exceeds the corresponding average percentage for the companies included in the 2015 Radford Global Life Sciences Survey by 18% and 24%, respectively. Based on these metrics, our compensation structure is more heavily weighted toward long-term components versus short-term pay, thus promoting a long-term perspective among our executives.

Despite the reductions in the annual grant of stock options to our Named Officers described above, therespective aggregate grant date fair valuevalues (disregarding estimated forfeitures) of PSUs or RSAs (as determined according to the Black-Scholes model for valuing stock options) of the stock options granted in 2015 is higher than the Black-Scholes grant date fair value of the larger number of stock options granted to Named Officers in prior years. This increase in the Black-Scholes value of annual stock option awards (and the corresponding increase in the value of total compensation for the Named Officers in 2015) is attributable largely to the higher market value of our common stock on December 16, 2015, the date of these option grants, compared to prior years. On December 16, 2015, the average of the high and low sales price per share of our common stock as quoted on the NASDAQ Global Select Market (used for calculating the grant date fair value) was $555.67, as compared to $399.66 on December 31, 2014 and $270.43 on December 13, 2013, the respective 2014 and 2013 grant dates.

In line with the goal of maintaining year-over-year consistency in making compensation decisions (regardless of stock price fluctuations), the Compensation Committee believes that the grant date fair value of the option award (as determined according to the Black-Scholes model for valuing stock options) is not the most appropriate measure for evaluating the grant. Rather, the Compensation Committee focuses more on the percentage of Regeneron's potential future share price appreciation that is shared by means of the award with the executive, expressed as the number of shares underlying the option award relative to the number of outstanding shares.

The following chart shows the decrease in the 2012 - 2015 annual stock option awards to our Chief Executive Officer both based on the number of shares underlying the awards and as

a percentage of the applicable number of outstanding shares of Regeneron common and Class A stock:

Share percentages are based on 96.6 million, 99.4 million, 101.7 million, and 104.1 million of shares (in each case consisting of common stock and Class A stock) outstanding as of October 12, 2012, October 28, 2013, October 16, 2014, and October 16, 2015, respectively, as reported in Regeneron's Quarterly Report on Form 10-Q for the third quarter of the applicable year.

In recent years, we have experienced significant growth in employees to support our research & development and commercialization efforts. From 2012 to 2015, we increased our employee base by approximately 121%. While the number of recipients of stock awards continued to increase given our practice of making initial stock option awards to all new employees and annual stock option awards to eligible employees whose performance is determined to merit an annual grant, we managed our utilization of stock awards judiciously, reducing our burn rate from the 2012 level and achieving a three-year burn rate average of 4.1% in 2015, in line with our current burn rate goal of 4%. We achieved this reduction through implementing three consecutive double-digit percentage decreases in the number of shares underlying annual stock option awards, without eliminating the broad-based nature of our equity compensation program.

Burn rate calculated by dividing the number of shares subject to equity awards (time-based and performance-based stock options and restricted stock) granted during the year by the weighted-average number of shares of common stock (including unvested restricted stock) and Class A stock outstanding during the year. A multiplier of 2 is applied to restricted stock awards. Headcount numbers based on the number of employees as of December 31 of the applicable year.

In addition, in the last three years when we implemented the stock option award reductions described above, we managed either to decrease our burn rate or to keep the percentage increase in our burn rate significantly below the percentage increase in the number of our employees. The 2015 increase in our burn rate compared to the prior year is wholly attributable to the rapid hiring of new key employees (as evidenced by a 47% increase in the number of employees over the same period), not increased sharing with our Named Officers (whose stock options grants declined).

Market Competitiveness and Employee Retention

In determining the appropriate size of stock option awards to executives, including the Named Officers, the Compensation Committee primarily considers the number of shares underlying the awards relative to the number of basic shares of common stock outstanding and not the grant date fair value of the award (as determined according to the Black-Scholes model). The Compensation Committee is therefore able to evaluate such grants on a consistent basis as compared to other companies and regardless of fluctuations in the price of Regeneron's or other companies' common stock. Further, focusing on the number of shares and the incremental sharing rate of potential future upside (rather than targeting a specific Black-Scholes grant date fair value) avoids rewarding officers with larger grant sizes following a decline in our stock price. The following chart displays the 2015 annual stock option award to our Chief Executive Officer as a percentage of the total basic shares outstanding, as compared to the 75th percentile and the 50th percentile of the companies included in the 2015 Radford Global Life Sciences Survey, showing that the size of his 2015 annual award was significantly below the 75th percentile and only slightly above the 50th percentile. It also shows that this award was below the 50th percentile of our Biotech R&D Peers.

Based on 2015 stock option award information reported in the Summary Compensation Table included in this proxy statement for Regeneron; data relating to grants of equity awards from the 2015 Radford Global Life Sciences Survey (comprising U.S. public biotechnology and pharmaceutical companies that have between 800 and 15,000 employees); and 2014 information available for Regeneron's Biotech R&D Peers (as defined in "Section 3 – Executive Compensation Process and Considerations – Peer Group"). The share information is based on 104.1 million shares (consisting of common stock and Class A stock) of Regeneron outstanding as of October 16, 2015 (as reported in Regeneron's Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2015) and on the number of shares outstanding reported in the 2015 Radford Global Life Sciences Survey for each of the companies included in the survey.

We believe that the structure of our executive compensation program encourages innovation, attracts talent with entrepreneurial spirit, increases employee engagement, and improves employee retention and the continuity of executive leadership during a critical period of growth. We regard our stock option grants as a key employee and executive retention tool. As stock option awards to our employees vest over time, generally over four years, they provide an incentive for the employee to continue to contribute to our success. Historically,

stock options have helped us maintain a motivational level of total compensation for our Named Officers and other eligible employees, while conserving the Company's cash. We believe that this has helped us to successfully grow and manage employee attrition, as evidenced by our 2015 employee turnover of approximately 6%, which compares favorably to the average employee turnover of approximately 18% for the life sciences sector based on the Fourth Quarter 2015 Radford Global Life Sciences Trends Report. In addition, stock options have allowed us to attract and retain entrepreneurial employees and foster an ownership culture. Moreover, granting stock options as long-term incentives to executives is standard practice in our industry and is an important part of our effort to attract, retain, and motivate high-quality talent.

In light of these considerations, we continued our practice of annual stock option grants in 2015, although we again (for the third consecutive year) reduced the number of shares underlying the annual stock option awards to the Named Officers as described above to reduce the potential dilutive impact of executive awards without adversely affecting the effectiveness of our executive compensation program, which has successfully motivated our senior management team to deliver high operating performance and shareholder value. In light of the fierce competition for talent in our industry, we believe that it is important to continue to motivate our existing employees, including the Named Officers, through stock option awards and to ensure that they share in the success of Regeneron.

We provide our Named Officers with a limited number of perquisites and other personal benefits. These benefits, which are described in greater detail under "Section 4 – Elements of Executive Compensation – Perquisites and Other Personal Benefits" below, are periodically reviewed by the Compensation Committee.

Section 3 – Executive Compensation Process and Considerations

Overview

The Compensation Committee is responsible for overseeing the Company's general compensation objectives and programs. The Compensation Committee evaluates the performance of our Named Officers and approves compensation for the Named Officers (in the case of the Chief Executive Officer, subject to first obtaining the approval of the non-employee members of the board of directors). The Compensation Committee operates under a written charter adopted by the board of directors and regularly reviews and reassesses the adequacy of its charter. A copy of the current charter is available on our website atwww.regeneron.com under the "Corporate Governance" heading on the "Investors & Media" page.

Members of our senior management play a significant role in the overall executive compensation process and assess performance of other officers. They also recommend, for Compensation Committee approval, salary, bonus, and stock option grant budgets for non-officers and make specific recommendations for salary increases, bonuses, and equity award grants for other officers. For our Named Officers (other than our Chief Executive Officer), recommendations to the Compensation Committee regarding their compensation are made by, or with the approval of, our Chief Executive Officer, who also evaluates their performance. Our Chief Executive Officer's performance is evaluated directly by the Compensation Committee based on our overall corporate performance

Executive Compensation

against annual goals that are approved by the board of directors at the beginning of each year, as discussed in more detail below.

The Compensation Committee has the sole authority to retain, at our expense, one or more third-party compensation consultants to assist the Compensation Committee in performing its responsibilities and to terminate the services of the consultant if the Compensation Committee deems it appropriate. In 2015, the Compensation Committee utilized the services of Frederic W. Cook & Co. to assist it in fulfilling its responsibilities. In order to maintain its independence, Frederic W. Cook & Co. was retained directly by the Compensation Committee and performed projects at the Compensation Committee's direction. The Compensation Committee's consultant reviews management recommendations on compensation plans, budgets, and strategies and advises the Compensation Committee on regulations and trends in executive compensation nationally and specifically in the pharmaceutical and biopharmaceutical industries. The Compensation Committee's consultant provides comparative compensation information for our Chief Executive Officer and other senior executives (using the Peer Group and other compensation data as described below), reviews senior management's compensation recommendations for other officers, including the other Named Officers, and provides general advice to the Compensation Committee on compensation matters, including facilitating the articulation and periodic review of the Company's compensation philosophy.

Annual salaries for the following year and year-end bonusesapplicable) and stock option awards granted in 2020, 2019, and 2018, respectively, pursuant to the Second Amended and Restated Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan or other year-end equity awards for all employees are determined in December of each year based on Companyits predecessor. Valuation assumptions and individual performance, as well as other factors, including compensation trends among our Peer Group andmethodologies used in the biotechnology industry in general. The 2015 salaries and 2014 year-end bonuses and stock option awards for our Named Officers were established by the Compensation Committee in December 2014. In November and December 2015, the Compensation Committee reviewed the performancecalculation of each of the Named Officers and presented its recommendations for 2016 salaries and 2015 year-end bonuses and equity awards for the Named Officers to the non-employee members of the board of directors for concurrence. With respect to our Chief Executive Officer, this process is formalized in the charter of the Compensation Committee, which specifies that the Compensation Committee is to annually present the proposed annual compensation of the Chief Executive Officer to the non-employee members of the board of directors for approval.

Peer Group

For purposes of setting compensation of our Chief Executive Officer, our Chief Scientific Officer, the other Named Officers, and other senior executives, we use comparative compensation information from a relevant peer group of companies ("Peer Group"). The companies in the Peer Group are selected by the Compensation Committee, with the assistance of Frederic W. Cook & Co., based on factors including, but not limited to, market capitalization, geographic location, number of employees, therapeutic focus, research and development expenditures, stage of development, total revenues, and product sales. The Company's trailing revenue size, number of employees, operating earnings, and market capitalization are all nearly in the middle of the range of the current Peer Group companies. The Peer Group is also meant to provide a representative sample of companies with which we compete for talent. The Compensation Committee periodically reassesses the composition of the companies within the Peer Group and makes changes as appropriate, taking into account factors such as changes in the Company's market capitalization and merger-and-acquisition activity impacting the existing Peer Group companies. In September 2015, the Compensation Committee approved a new Peer Group based on the recommendation of its compensation consultant, Frederic W. Cook & Co.. The changes to the Peer Group were as follows: (i) elimination of Cubist Pharmaceuticals, Inc. in light of the fact that it had been acquired by Merck & Co., Inc.; (ii) elimination of Seattle Genetics, Inc. due to its market capitalization being significantly below Regeneron's; and (iii) addition of Alkermes plc and Alnylam Pharmaceuticals, Inc., both of which are biopharmaceutical companies with a business model the Compensation Committee considered similar to Regeneron's. In approving the new Peer Group, the Compensation Committee also took into account that, as of the approval date, Regeneron was the median company in the Peer Group based on market capitalization, revenues for the last four completed quarters, and the then-available reported number of employees, as shown in the table below.

In making its compensation decisions in December 2015, the Compensation Committee used data from publicly filed proxy statements of the companies in the Peer Group (as compiled by its compensation consultant) to review each element of compensation of our Named Officers against their peers in the Peer Group as well as their total annual compensation in relation to the Peer Group, while taking into account various factors such as the executive's performance, past compensation history, experience, and the role in the Company's success. We use Peer Group data as a point of reference for measurement, but Peer Group data do not represent the only factor considered and there is no targeted pay level percentile. Further, in its review of the Peer Group data, the Compensation Committee also considers the practices of the 10-company sub-group of peers viewed as having businesses and drug discovery cultures that are most similar to Regeneron's, with similarly-sized employee bases (marked with an asterisk

in the table above and referred to as "Biotech R&D Peers"). The Compensation Committee retains discretion in determining the nature and extent of the use of Peer Group data. In addition, in 2015 management and the Compensation Committee reviewed compensation data for biotechnology companies from the 2015 Radford Global Life Sciences Survey (comprising U.S. public biotechnology and pharmaceutical companies that have between 800 and 15,000 employees) to obtain a general understanding of current compensation practices and to assess overall competitiveness of our compensation program.

Compensation Consultant Independence

In accordance with applicable listing standards of the NASDAQ Stock Market LLC and SEC rules, the Compensation Committee evaluated in 2015 the independence of Frederic W. Cook & Co.,

including by taking into consideration the following factors:

the fact that Frederic W. Cook & Co. did not provide any other services to the Company;

the amount of fees received from the Company by Frederic W. Cook & Co. as a percentage of its revenue;

the policies and procedures of Frederic W. Cook & Co. designed to prevent conflicts of interest;

the absence of any significant business or personal relationship between Frederic W. Cook & Co. and any member of the Compensation Committee;

the fact that Frederic W. Cook and the representative of Frederic W. Cook & Co. to the Company did not own any stock of the Company; and

the absence of any material business or personal relationship between Frederic W. Cook & Co. and any executive officer of the Company.

The Compensation Committee's evaluation was based in part on a representation letter from Frederic W. Cook & Co.. On the basis of this evaluation, the Compensation Committee concluded that the engagement of Frederic W. Cook & Co. did not raise any conflicts of interest.

Stock Ownership Guidelines

To further align the interests of senior management with the interests of shareholders and promote a long-term perspective, the board of directors has adopted stock ownership guidelines for members of senior management, including the Named Officers, and the members of the board of directors. The guidelines are reviewed periodically by the Corporate Governance and Compliance Committee. Pursuant to these guidelines, these individuals are expected to meet share ownership targets that are determined based on their position and their base salary. The share ownership targets are as follows:

Chairman of the Board and Chief Executive Officer, six times (6x) base salary;

Chief Scientific Officer, three times (3x) base salary;

Executive/Senior Vice Presidents, two times (2x) base salary; and

non-employee members of the board of directors, six times (6x) the annual retainer.

Covered individuals who do not currently meet these guidelines have five years from becoming subject to the policy to reach their target. Members of senior management who are

hired or promoted, and directors who join the board of directors, have five years from such date to reach their target. Shares held directly, shares held indirectly through our 401(k) Savings Plan, shares held in trust, and shares held by immediate family members residing in the same householdamounts are included in determining an individual's share ownership. Unexercised stock options and unvested restricted stock are not considered ownedNote 12 to the Company’s audited financial statements for purposes of these guidelines. All directors and officers have either met their respective share ownership targets or are still within the five-year period for achieving compliance.

Say-on-Pay Response

Our shareholders are provided with an opportunity to cast a non-binding, advisory vote every three years on our executive compensation program. Our shareholders most recently had the opportunity to cast advisory say-on-pay votes at our annual shareholder meeting held in June 2014, at which approximately 62% of the votes cast supported the advisory vote proposal on our executive compensation program. Management and the Compensation Committee carefully considered the results of the most recent say-on-pay vote. Senior members of our management as well as the Chairman of the Compensation Committee subsequently spent a significant amount of time speaking with some of our key shareholders about executive compensation and corporate governance. As part of our 2014 engagement effort, we discussed these issues with shareholders collectively representing approximately 47% of the shares of common stock outstanding as offiscal year ended December 31, 2014 (excluding shares held our directors and executive officers and Sanofi). Following2020 included in the 2014 discussions, we implemented several changes2020 Annual Report.

We reduced the number of shares underlying the 2014 annual stock option awards to the Named Officers by an average of 16% compared to the prior year (without giving effect to a grant to our Chief Financial Officer, who did not receive an annual stock option award in 2013 because he joined the Company in September 2013).

We eliminated certain perquisites of our Chief Executive Officer and our Chief Scientific Officer we considered no longer consistent with our overall compensation program, including, in the case of our Chief Executive Officer, a tax gross-up related to legal, tax, and financial planning advisory services.

Table of Contents

We adopted a policy against including excise tax gross-up provisions with respect to payments contingent upon a change in control of Regeneron in contracts, compensatory plans, or other arrangements with the Company's executive officers, including the Named Officers (other than the existing employment agreement with our Chief Executive Officer or any amendments thereto, which we expressly exempted).
We provided additional information regarding compensation decisions and our compensation philosophy in the Compensation Discussion and Analysis of our 2015 proxy statement to better communicate to our shareholders what drives compensation decisions at Regeneron.

We will continue to consider the outcome of our past and future advisory vote results. Our shareholder engagement efforts and implementation of compensation and governance initiatives continued in 2015, as described further below under "2015 Shareholder Outreach."

2015 Shareholder Outreach

We have instituted an ongoing shareholder outreach program through which we seek input from our institutional investors and other shareholders regarding our executive compensation and other governance practices, and implement appropriate changes based on this input. We value shareholder views and insights and believe that constructive and meaningful dialogue allows us to develop broader relationships with investors over the long-term and builds informed relationships that promote transparency and accountability. We continued our shareholder outreach efforts in 2015 and engaged in discussions with shareholders collectively representing approximately 47% of the shares of common stock outstanding as of December 31, 2015 (excluding shares held our directors and executive officers and Sanofi). Below is a summary of recent changes we have adopted based on shareholder feedback and other relevant considerations:

Continue to implement corporate governance best practicesAdopted majority voting standard in the election of directorsJanuary 2016

Consideration of Risk in Company Compensation Policies

The Compensation Committee regularly reviews the Company's compensation and benefits programs, including its executive compensation program and its incentive based compensation programs for commercial personnel. Our compensation and governance-related policies are further enhanced by our stock ownership guidelines applicable to our senior officers and our policy regarding recoupment or reduction of incentive compensation of our officers and other specified employees for compliance violations, as well as a policy against hedging and pledging of our securities by our directors and employees, including the Named Officers. We have also adopted a policy against including excise tax gross-up provisions with respect to payments contingent upon a change in control of Regeneron in

contracts, compensatory plans, or other arrangements with the Company's executive officers, including the Named Officers (other than the existing employment agreement with our Chief Executive Officer or any amendments thereto, which we expressly exempted). These policies evidence Regeneron's continued commitment to robust corporate governance and are meant to reduce compensation-related risks and ensure greater alignment of the interests of our employees, including the Named Officers, and those of the Company and our shareholders.

We believe that the Company's programs balance risk and potential reward in a manner that is appropriate to the Company's circumstances and in the best interests of the Company's shareholders over the long term. We also believe that

53

the Company's compensation and benefits programs do not create risks that are reasonably likely to have a material adverse effect on the Company.

Tax Implications

Section 162(m) of the Internal Revenue Code limits the deductibility for federal income tax purposes of compensation in any year paid to the Chief Executive Officer and the other Named Officers (other than the Chief Financial Officer) to the extent such compensation exceeds $1 million and does not qualify as "performance-based" compensation as defined under Section 162(m) of the Internal Revenue Code. The Company has adopted (and the shareholders approved at the 2015 annual shareholder meeting) the Regeneron Pharmaceuticals, Inc. Cash Incentive Bonus Plan. Awards under the Plan (as well as awards under the previously approved Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan) may, but

are not required to, be subject to the attainment of performance goals in order to qualify for this performance-based compensation exception. The Compensation Committee has implemented the Cash Incentive Bonus Plan for annual cash bonuses of the Named Officers in respect of performance in 2016.

The Compensation Committee takes into account the deductibility of compensation in determining Named Officer compensation. However, the Compensation Committee reserves the right to use its judgment to authorize compensation payments that are not deductible, such as when the Compensation Committee believes that such payments are necessary to maintain the flexibility needed to attract talent, promote executive retention, or reward performance, or as required to comply with the Company's contractual commitments. As noted above, compensation attributable to stock options generally qualifies as "performance-based" compensation and, as such, receives favorable treatment under Section 162(m) of the Internal Revenue Code.

Section 4 – Elements of Executive Compensation

Our executive compensation program currently has five components:

base salary;

annual cash bonus;

annual equity awards, typically consisting of stock options;

certain perquisites and other personal benefits; and

potential severance benefits.

Base Salary

We provide the Named Officers and other employees with base salary to compensate them for services rendered during the fiscal year and provide them with a regular monthly income. In determining base salaries for our Named Officers, the Compensation Committee considers the executive's scope of responsibilities, experience, annual performance, and future potential or role in future success. The Compensation Committee also considers base salaries for comparable positions in our geographic region, competitive salary practices of companies in the Peer Group and the broader biopharmaceutical industry, and annual inflation levels.

For each of 2015 and 2016, each of the Named Officers received a merit increase of 3.5% of his 2014 and 2015 base salary, respectively (which were in addition to the other increases discussed for the Named Officers below). In addition, for 2015, Dr. Schleifer received a base salary increase of

$91,300, which aligned his base salary with that of the median of the companies included in the 2014 Radford Global Life Sciences Survey and below the median of the Peer Group (as in effect in 2014), and Dr. Yancopoulos received a base salary increase of $77,600 to set his base salary at 85% of Dr. Schleifer's. Dr. Yancopoulos's cash compensation, including base salary, is set at 85% of Dr. Schleifer's, which we believe is more appropriate for him in light of the absence of meaningful comparative data for similarly situated executives. Further, for 2015, Dr. Stahl received a $39,200 base salary increase in connection with his promotion to Executive Vice President, Research and Development and Mr. Terifay received a $50,000 base salary increase, in each case to better align his base salary with relevant industry comparative information. For 2016, Dr. Stahl and Mr. Landry received a $50,000 base salary increase each in order to better align their base salaries with relevant industry comparative information. The determinations regarding the 2015 and 2016 merit increases were based on broad-based national data for high-performing, larger biotechnology companies. In each of 2015 and 2016, the base salaries of the Named Officers were set at or below the median of the Peer Group (other than with respect to Dr. Yancopoulos, whose cash compensation, including base salary, is set at 85% of Dr. Schleifer's (as noted above)).

Annual Cash Bonus

It has been our practice to offer annual cash bonus opportunities to our Named Officers. The Compensation Committee focuses exclusively on our overall corporate performance when determining the annual cash bonus for our Chief Executive Officer and Chief Scientific Officer. The cash bonuses of the other Named Officers are based both on overall corporate performance and their individual contributions and performances during the year. We historically had no formal bonus plan and the award of any bonus to a Named Officer was based on an assessment of corporate and, in the case of Named Officers other than Dr. Schleifer, individual performance. We believe that this approach, rather than working from a rigid bonus formula or plan, was beneficial given the growth trajectory of the Company and its rapid transformation over the past few years from a development-stage company to a fully integrated, commercial-stage biopharmaceutical company. In 2015, the Company adopted, and the shareholders approved, the Regeneron Pharmaceuticals, Inc. Cash Incentive Bonus Plan. The Compensation Committee has implemented the Cash Incentive Bonus Plan for annual cash bonuses of the Named Officers in respect of performance in 2016.

The 2015 cash bonus target for the Chief Executive Officer was 100% of his base salary. In December 2015, the board of directors approved an increase in the Chief Executive Officer's cash bonus target to 120% of his base salary to bring Dr. Schleifer's target annual cash compensation to the median of the companies included in the 2015 Radford Global Life Sciences Survey. For 2016, Dr. Schleifer's target cash compensation remained below the median of the Peer Group. Consistent with Regeneron's historical practice, the increase was given effect in the calculation of Dr. Schleifer's cash bonus paid in respect of 2015. The Chief Executive Officer

recommended 2015 target bonuses for the other Named Officers, which were reviewed and approved by the Compensation Committee. In December 2015, the Compensation Committee increased the cash bonus target for Mr. Landry and Mr. Terifay to 50% and 60% of their respective base salaries; consistent with Regeneron's historical practice, these increases were given effect in the calculation of their cash bonuses paid in respect of 2015. In determining the cash bonus targets for 2015 for Mr. Landry, Dr. Stahl, and Mr. Terifay, the Compensation Committee took into consideration the compensation of similarly situated executive officers at companies in the Peer Group and, in the case of Mr. Terifay, also his promotion to Executive Vice President, Commercial.

In determining the cash bonus target for Dr. Yancopoulos, the Compensation Committee took into consideration the importance of his scientific leadership as President of Regeneron Laboratories and Chief Scientific Officer and the significant contributions he has made to the success of the Company and, specifically, to the discovery and development of the Company's commercial products, its pipeline of internally developed product candidates, and its platform technologies.

The Compensation Committee determined that for Dr. Yancopoulos there were no meaningful comparative data relating to similarly situated executives and that his base salary, cash bonus, and annual stock option awards would be set at 85% of Dr. Schleifer's. The 2015 cash bonus target for Dr. Yancopoulos was 120% of his base salary (increased in connection with the increase of Dr. Schleifer's cash bonus target as described above). These cash bonus targets are consistent with the Company's emphasis on performance-based compensation and are set at or below the median of the Peer Group (other than with respect to Dr. Yancopoulos, whose cash compensation, including cash bonus, is set at 85% of Dr. Schleifer's).

In December 2015, our Named Officers were awarded the following cash bonuses, which were paid in January 2016.

depending upon performance during the year. Both the personal performance multiplier and the Company performance multiplier were determined by the Compensation Committee for each Named Officer based on the Committee's assessment of the Company's performance relative to the general corporate goals described below and, in the case of each of Mr. Landry, Dr. Stahl, and Mr. Terifay, the Named Officer's personal performance during the year.

The Compensation Committee determined that the Company's performance in 2015 well exceeded its 2015 corporate goals. These corporate achievements included the following:

47% growth in EYLEA® global net product sales as compared to 2014;

46% growth in our total revenues as compared to 2014;

19% growth in non-GAAP net income as compared to 2014 (non-GAAP net income is not a measure calculated in accordance with U.S. Generally Accepted Accounting Principles; see Appendix A for a definition of non-GAAP net income and a reconciliation of non-GAAP net income to net income);

advances in our EYLEA® franchise, including regulatory approval of EYLEA® for the treatment of visual impairment due to macular edema secondary to retinal vein occlusion and the treatment of visual impairment secondary to myopic choroidal neovascularization in the European Union; regulatory approval of EYLEA® for the treatment of diabetic retinopathy in patients with diabetic macular edema in the United States; and regulatory approval of EYLEA® for the treatment of retinal vein occlusion in Japan;

approval and launch of Praluent® (alirocumab) Injection, the first FDA-approved drug in a new class of drugs that lower LDL ("bad") cholesterol;

positive Phase 3 data for sarilumab from three Phase 3 studies in patients with rheumatoid arthritis (SARIL-RA-TARGET, SARIL-RA-EASY, and SARIL-RA-ASCERTAIN) and submission of a Biologics License Application for sarilumab with the FDA;

positive pivotal Phase 2b data for dupilumab in asthma and completion of enrollment of the dupilumab atopic dermatitis Phase 3 studies;

new collaboration agreement relating to fasinumab with Mitsubishi Tanabe Pharma Corporation for Japan, Korea, and nine other Asian countries, excluding China;

initiation of Phase 3 clinical study of REGN2222 for Respiratory Syncytial Virus;

continued growth of our clinical development pipeline, as evidenced by the submission of one Investigational New Drug Application with the FDA in 2015 and 13 product

candidates (consisting of one Trap-based and 12 fully-human monoclonal antibody product candidates based on the Company'sVelocImmune® technology) in clinical development as of December 31, 2015;

new global strategic collaboration with Sanofi to discover, develop, and commercialize antibody-based cancer treatments in the field of immuno-oncology; and

further important steps to support our current and future growth, including adding two new buildings in the Tarrytown campus providing nearly 300,000 square feet of additional laboratory and office space; significant progress with the construction of a new manufacturing facility in Limerick, Ireland; and increasing headcount on a year-over-year basis by approximately 47% as of December 31, 2015.

See "Section 1 – Summary – 2015 Performance Overview" above for additional information.

In recognition of these significant achievements, the Company performance multiplier for 2015 was set at 2.0.

With respect to 2015, the Compensation Committee approved a personal performance multiplier of 1.5 for each of Mr. Landry, Dr. Stahl, and Mr. Terifay. The personal performance component accounted for 40% of these officers' bonuses. The Company component was based on a Company performance multiplier that was determined based on the Company's overall corporate performance (as described above) against 2015 goals that were approved by the board of directors in January 2015. This Company performance component accounted for 60% of the bonuses awarded to Mr. Landry, Dr. Stahl, and Mr. Terifay. In the case of Drs. Schleifer and Yancopoulos, the Compensation Committee focused exclusively on our overall Company performance in 2015 (as described above) when determining their cash bonuses and did not utilize a personal performance multiplier.

In determining the personal performance multiplier for Mr. Landry, the Compensation Committee gave special consideration to Mr. Landry's leadership of and accomplishments in the Company's accounting and finance functions and his assumption of additional responsibilities since he joined the Company in September 2013. In the case of Dr. Stahl, the Compensation Committee focused on the progress and continued expansion of the Company's preclinical and clinical development pipeline, including the positive results from the Company's clinical trials reported in 2015, as summarized in "Section 1 – Summary – 2015 Performance Overview" above. In the case of Mr. Terifay, the Compensation Committee focused primarily on the continued commercial success of EYLEA® and the fact that EYLEA® U.S. net product sales in 2015 grew by 54% compared to 2014; the launch of Praluent® in 2015; and his leadership of the Company's commercial group, including the increase in his responsibilities in

connection with the expansion of the commercialization group to support the launch of Praluent® and the planned launches of sarilumab and dupilumab.

Annual Stock Option Awards

We have used stock option grants as the primary vehicle for offering long-term incentives and rewarding our Named Officers and other eligible employees. These time-based stock options generally vest at a rate of 25% per year over the first four years of the ten-year option term, subject to the executive's continued employment. We grant stock option awards to our Named Officers and other eligible employees based on their annual performance and their position and responsibilities with the Company. Each of our Named Officers generally receives an annual stock option grant and all of our other regular employees are also eligible for an annual stock option grant, subject to satisfactory performance. The number of stock options granted to each Named Officer is determined on a discretionary basis, rather than by a formula. The Compensation Committee primarily considers the number of shares underlying the awards relative to the number of basic shares of common stock outstanding and not the grant date fair value of the award (as determined according to the Black-Scholes model). The Compensation Committee is therefore able to evaluate such grants on a consistent basis as compared to other companies and regardless of fluctuations in the price of Regeneron's or other companies' common stock. Further, focusing on the number of shares and the incremental sharing rate of potential future upside (rather than targeting a specific Black-Scholes grant date fair value) avoids rewarding officers with larger grant sizes following a decline in our stock price. While the Compensation Committee takes the estimated Black-Scholes grant date fair value of annual stock option grants into account, it does not necessarily determine its compensation decisions.

It has been the practice of our Compensation Committee to grant annual stock option awards to eligible employees whose performance is determined to merit an annual grant, including the Named Officers, at a meeting held during December. In 2015, stock option awards (all of which were non-qualified stock options) were granted to our Named Officers and other eligible employees on December 16, 2015. Pursuant to the terms of the Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan, stock option awards are granted, for so long as our common stock is listed on the NASDAQ Global Select Market, with an exercise price equal to the

average of the high and low sales price per share of our common stock as quoted on the NASDAQ Global Select Market on the date of the grant or, if such date is not a trading day, on the last preceding date on which there was a sale of our common stock on the NASDAQ Global Select Market.

All of the stock options granted to our Named Officers in 2015 will vest ratably over a period of four years. Except as set forth below under the heading "Post-Employment Compensation" on page 66, stock option vesting ceases, and unvested stock options are forfeited, upon termination of employment. The use of only time-based stock options is consistent with the Company's practice prior to 2008 and since 2012.

Our Named Officers received a grant of time-based stock options on December 16, 2015, as set forth below. The annual grants shown below reflected an average reduction of 15% compared to 2014 (other than Mr. Terifay's award, which remained at the 2014 level due to his promotion to Executive Vice President, Commercial). This decrease constituted the third consecutive double-digit percentage decrease in the annual grant of stock options to our Named Officers, in each case following outstanding TSR performance. In reducing the size of 2015 annual stock option awards to the Named Officers, the Compensation Committee sought to reduce the potential dilutive impact of new equity awards without adversely affecting the effectiveness of our executive compensation program, which has successfully motivated our senior management team to deliver high operating performance and shareholder value. The reduction also took into account the increase in the Company's stock price in recent years. We will continue to assess the number of stock options that will be awarded to the Named Officers as annual merit grants.

​  
How did we determine the size of our 2015 annual Named Officer stock option awards?


The size of the time-based stock option awards granted to our Named Officers were based on the following six factors:

past Company practices (i.e., history of grants to relevant executives);

an assessment of each Named Officer's 2015 performance against the Named Officer's goals, as established by our CEO (in the case of the Named Officers other than our Chief Executive Officer) and the Compensation Committee (in the case of our Chief Executive Officer), as described above under "– Annual Cash Bonus";

Regeneron's significant corporate accomplishments in 2015;

recognition that cash compensation of the Named Officers is generally positioned at or below the median of the Peer Group despite the fact that Regeneron is a high-growth, high-performing company, which supports a higher level of equity grants;


an evaluation of the awards as a percentage of the total basic shares outstanding as compared to Peer Group and survey data, in particular the 2015 Radford Global Life Sciences Survey (see "Section 2 – Analysis of 2015 Executive Compensation Based on Compensation Objectives – Market Competitiveness and Employee Retention"); and

the increase in the Company stock price since the annual stock option awards in 2014 and prior years, with the resulting increase in the grant date fair value of the 2015 annual stock option awards (as determined according to the Black-Scholes model for valuing stock options), which contributed to the decision to implement the third consecutive double-digit percentage reduction in the annual grant of stock options to our Named Officers (for information regarding our burn rate since 2012, see "Regeneron Stock Utilization vs. Headcount" on page 48).

As noted above, Dr. Yancopoulos's 2015 annual stock option award was set at 85% of Dr. Schleifer's (consistent with other elements of his compensation and our historical practice).


Perquisites and Other Personal Benefits

The Named Officers are provided with a limited number of perquisites and other personal benefits. The Compensation Committee periodically reviews the perquisites and other personal benefits provided to the Named Officers, including the Chief Executive Officer.

All of the Named Officers are eligible to receive financial and tax planning assistance, which are taxable benefits and are meant to save the executives time in order to focus on business matters as well as to recognize that their tax situations are affected by their employment at Regeneron. Similar to other employees, the Named Officers may participate in company-wide health, disability, life insurance, and other benefit plans, as well as our 401(k) Savings Plan. All employees who participate in our 401(k) Savings Plan are eligible to receive certain matching contributions. In each plan year, we contribute to each participant's account a matching contribution (in the form of shares of our common stock) equal to 50% of a specified percentage of the participant's compensation that the participant has contributed to the plan (which was 6% with respect to each of 2013 and 2014 and 8% with respect to

2015), up to a maximum level established under the Internal Revenue Code. In addition, for 2014, the Company made an additional discretionary contribution equal to 1% of each eligible employee's salary. Each of our Named Officers participated in our 401(k) Savings Plan during 2015 and received a matching contribution in the aggregate amount of $10,600 in the form of shares of our common stock. The contribution was paid in February 2016 and is included in the compensation amounts reported for each of our Named Officers in the Summary Compensation Table included in this proxy statement. As with all employees, the number of shares of common stock that each Named Officer received was determined using the average market price per share of our common stock during the 401(k) Savings Plan year, which for 2015 was $498.52.

Our Chief Executive Officer is entitled to life insurance, long-term disability, and medical malpractice insurance premiums (as well as an additional amount for tax preparation and financial planning services) pursuant to the terms of his employment agreement, as described in footnote 5 to the Summary Compensation Table included in this proxy statement. Pursuant to the terms of our security policy, the Company's Chief Executive Officer and Chief Scientific Officer are

58

Executive Compensation


Table of Contents

required, to the extent practicable, to utilize personal travel security services, on-site residential security at their primary residence, and secure car transportation. We calculate the aggregate incremental cost to Regeneron for secure car transportation as the portion of the invoiced amount from our third-party provider of such transportation that is attributable to personal use based on the number of hours used, without including fixed costs that would be incurred in any event.

In addition, in order to ensure increased efficiencies and to provide a more secure traveling environment, the Company utilizes on-demand air transportation for certain executive and director travel in accordance with guidelines approved by our board of directors. Based on the recommendation of an independent, third-party security study, the guidelines and our security policy (as amended in November 2015) require Drs. Schleifer and Yancopoulos (as well as their spouses and dependent children when they accompany them) to use, as much as practicable, Company-provided aircraft for all business and personal air travel. Starting in 2016, Regeneron will cover the cost of any such personal air travel for up to $250,000 in incremental cost annually for each of Drs. Schleifer and Yancopoulos. Family members or other guests may accompany our Named Officers and directors during on-demand air business travel, space permitting, so long as they cover any incremental cost related to such guests (other than with respect to the family members of Drs. Schleifer and Yancopoulos as described above). In addition, in limited circumstances personal use of on-demand air travel by our other Named Officers or directors may be permitted if authorized by the Chairman and any incremental cost is paid by the lead passenger. Any required reimbursement or other payment of the incremental cost is made to the extent permitted by applicable Federal Aviation Administration rules.

There was no unreimbursed personal use, or guest use resulting in any incremental cost to us, of Company-provided aircraft in 2015.

The Corporate Governance and Compliance Committee monitors business and any personal or guest on-demand air travel on a periodic basis.

Additional information regarding perquisites and other personal benefits provided to our Named Officers in, or with respect to, 2015 is given in the applicable footnotes to the Summary Compensation Table included in this proxy statement.

Potential Severance Benefits

Outstanding stock option award agreements (as well as outstanding restricted stock award agreements) for all employees (other than Dr. Vagelos, whose stock option awards contain change-of-control provisions consistent with those of non-employee director stock option awards, as described under "Corporate Governance – Compensation of Directors" above) include a "double trigger" provision for the acceleration of vesting of unvested stock options (or restricted stock) upon a termination by the Company without cause or by the employee for good reason within two years following a change in control. Our Chief Executive Officer has an employment agreement that provides for certain severance benefits following termination, including following death or disability, resignation following defined "good reason" events, or termination in connection with a change in control. The other Named Officers are covered by a change in control severance plan, which provides certain benefits to them and other designated officers if they are terminated in connection with a change in control. In addition, in the case of our Chief Scientific Officer, stock option and restricted stock award agreements applicable to his awards granted starting in December 2015 provide that he would have a "good reason" for terminating his employment with Regeneron upon or within two years after the occurrence of a change in control if the employment of our Chief Executive Officer has ended due to our Chief Executive Officer's involuntary termination (as defined in his employment agreement). Information regarding applicable payments under this employment agreement and change in control severance plan is provided under the heading "Post-Employment Compensation" on page 66.

Except as provided in our employment agreement with our Chief Executive Officer and in our change in control severance plan, our Named Officers will forfeit any unvested time-based stock options or restricted stock upon the termination of their employment for any reason (including disability or retirement) other than death. In the event of the death of an employee, any unvested stock options held by such employee become immediately exercisable, and any shares of restricted stock will become fully vested. For information regarding unvested stock options and shares of restricted stock held by our Named Officers as of December 31, 2015, see "Outstanding Equity Awards at Fiscal Year-End" on page 64. When employees (other than our Chief Executive Officer) retire, they forfeit all unvested time-based stock options and restricted stock. For all stock options granted prior to 2007, an employee (other than our Chief Executive Officer) who retires has up to two years to exercise stock options that are vested as of the date of his or her retirement. Commencing in 2007, we amended our forms of stock option agreement to allow the retired employee the remaining life of the 10-year stock option term to exercise stock options that are vested as of the date of his or her retirement.

The severance benefits provided to our Named Officers are designed to promote stability and continuity of our senior management and are intended to preserve employee morale and productivity and encourage retention in the face of the disruptive impact of an actual, threatened, or rumored change in control of the Company. The severance benefits were established following a review of comparable practices at the Company's peer companies and with the advice of the Compensation Committee's consultant. We have no pension, deferred compensation, or retirement plans, other than our 401(k) Savings Plan described above.

Post-Employment Compensation

POST-EMPLOYMENT COMPENSATION

As discussed in “Compensation Dashboard—Additional Compensation Information—Potential Severance Payments,” our NEOs are entitled to certain severance benefits upon the voluntary or involuntary termination of their employment. We provide additional information regarding the severance benefits available to our NEOs in the tables set out below in this subsection. For our CEO, the table shows the amounts payable under his employment agreement upon his involuntary or not-for-cause termination, termination in connection with a corporate change of control, and in the event of his disability or death. For the other NEOs, the table shows their post-termination compensation arrangements under our change in control severance plan upon an involuntary or not-for-cause termination in connection with a corporate change of control.

Leonard S. Schleifer, M.D., Ph.D., Employment Agreement

We entered into an employment agreement with our CEO, Dr. Schleifer, effective as of December 20, 2002, providing for his employment with the Company through December 31, 2003 and continuing thereafter on a year-by-year basis. On November 14, 2008, this employment agreement was amended and restated to bring the employment agreement into compliance with Section 409A of the Internal Revenue Code. Pursuant to this agreement, we agreed that in the event that Dr. Schleifer’s employment is terminated by us other than for cause (as defined in the agreement) or is terminated by Dr. Schleifer for good reason (as defined in the agreement to include specified acts of constructive termination, together called an “involuntary termination”), we will pay Dr. Schleifer an amount equal to 125% of the sum of his base salary plus his average cash incentive paid over the prior three years. This amount will be paid in a lump-sum severance payment. In addition, we will continue to provide Dr. Schleifer and his dependents medical, dental, and life insurance benefits for 18 months. Subject to the discussion in the following paragraph, in the event that Dr. Schleifer’s employment terminates for any reason other than for cause, (i) all of his unvested stock options will continue to vest in accordance with the terms of the applicable award grant and he will be entitled to exercise the stock options throughout their original term, which is generally ten years from the date of grant, and (ii) all of his unvested PSUs from the 2019 grant will remain outstanding, and vesting and forfeiture shall be determined in the manner set forth in the applicable award agreement, without regard to such termination of employment. For a discussion of the treatment of Dr. Schleifer’s unvested PSUs from the 2020 grant upon certain termination events, see “Compensation-Related Matters—Compensation Discussion and Analysis—Components of Executive Pay: What We Pay and Why We Pay It—Annual Equity Awards.”

As discussed under "Section 4 – Elements of Executive Compensation – Potential Severance Benefits" on page 59, our Named Officers are entitled to certain severance benefits upon the voluntary or involuntary termination of their employment. We provide additional information regarding the severance benefits available to our Named Officers in the tables on pages 67 and 69. For our Chief Executive Officer, the table shows the amounts payable under his employment agreement upon his involuntary or not-for-cause termination, termination in connection with a corporate change of control, and in the event of his disability or death. For the other Named Officers, the table shows their post-termination compensation arrangements under our change in control severance plan upon an involuntary or not-for-cause termination in connection with a corporate change of control.

    Leonard S. Schleifer, M.D., Ph.D., Employment Agreement

We entered into an employment agreement with our Chief Executive Officer, Dr. Schleifer, effective as of December 20, 2002, providing for his employment with the Company through December 31, 2003 and continuing thereafter on a year-by-year basis. On November 14, 2008, this employment agreement was amended and restated to bring the employment agreement into compliance with Section 409A of the

Internal Revenue Code. Pursuant to this agreement, we agreed that in the event that Dr. Schleifer's employment is terminated by us other than for cause (as defined in the agreement) or is terminated by Dr. Schleifer for good reason (as defined in the agreement to include specified acts of constructive termination, together called an "involuntary termination"), we will pay Dr. Schleifer an amount equal to 125% of the sum of his base salary plus his average bonus paid over the prior three years. This amount will be paid in a lump sum severance payment. In addition, we will continue to provide Dr. Schleifer and his dependents medical, dental, and life insurance benefits for eighteen months. Subject to the discussion in the following paragraph, in the event that Dr. Schleifer's employment is terminated for any reason other than for cause, all of his unvested stock options will continue to vest in accordance with the terms of the applicable award grant and he will be entitled to exercise the stock options throughout their original term, which is generally ten years from the date of grant.

Upon an involuntary termination (i.e., a termination by the Company without cause or by Dr. Schleifer for good reason, each as defined in the agreement) within three years after a change of control of the Company or within three months prior to such a change of control, we will pay Dr. Schleifer an amount equal to three times the sum of his annual base salary plus his average cash incentive over the prior three years. This amount will be paid in a lump-sum severance payment. In addition, we will continue to provide Dr. Schleifer and his dependents medical, dental, and life insurance benefits for 36 months. Upon such an involuntary termination in connection with a change of control, Dr. Schleifer’s outstanding stock options will vest immediately and remain exercisable throughout their original term, which is generally ten years from the date of grant. In addition, pursuant to the terms of his 2019 PSU award agreement, any such PSUs that vest upon a change of control (as a result of performance exceeding the relevant TSR goal for the

This amount will be paid in a lump sum severance payment. In addition, we will continue to provide Dr. Schleifer and his dependents medical, dental, and life insurance benefits for thirty-six months.

connection with a change of control, Dr. Schleifer's outstanding stock options will vest immediately and remain exercisable throughout their original term, which is generally ten years from the date of grant. If aggregate severance payments to Dr. Schleifer in connection with a change of control exceed certain thresholds set forth in the Internal Revenue Code, then we will pay him an additional amount to cover any resulting excise tax obligations, unless the excise taxes could be eliminated by reducing Dr. Schleifer's cash severance payments and benefits under the agreement by less than ten

percent, in which case such benefits and payments will be reduced accordingly.

The following table reflects the potential payments to our Chief Executive Officer under his employment agreement upon his termination, effective December 31, 2015, under different scenarios, including following a change of control, as well as upon death or disability. The information in the table below is based on the assumptions set forth in the footnotes to the table; actual values and amounts may differ from those presented below.

    Change in Control Severance Plan

Each of the Named Officers, other than our Chief Executive Officer, participates in our change in control severance plan that was adopted by the board of directors on January 20, 2006. The purposes of the plan are (i) to help us retain key employees, (ii) to help maintain the focus of such employees on our business and to mitigate the distractions caused by the possibility that we may be the target of an acquisition, and (iii) to provide certain benefits to such employees in the event their employment is terminated (or constructively terminated) after, or in contemplation of, a change in control. On November 14, 2008, the change in control severance plan was amended and restated to bring it into compliance with Section 409A of the Internal Revenue Code.

Under the plan, each participant is entitled to receive a cash severance payment in an amount equal to one, or, in designated cases, including with respect to the Named Officers other than Dr. Schleifer, two times the sum of the participant's annual base salary and his or her average annual bonus over the prior three years if, within two years after or 180 days before a change in control, either the participant resigns his or her employment for Good Reason (as defined in the plan) or the participant's employment is terminated by the Company for any reason other than Cause (as defined in the plan). This amount will be paid in a lump sum severance payment. A participant so terminated is also entitled to receive a pro rata bonus for the year in which he or she is terminated based on the portion of the year the participant was employed by us. In addition, for either one or two years, as the case may be, plan participants will receive continuation of health care coverage and welfare benefits provided by us, to the extent permitted by our benefit plans, at a cost no greater than what the participant's cost would have been if he or she had continued his or her employment with the Company.

In the event that a plan participant resigns his or her employment for Good Reason (which generally conforms to the definition in Section 409A), or the participant's employment is terminated by the Company for any reason other than Cause, in either case within two years after or 180 days before a change in control, then the participant's stock options and other equity awards granted under our long-term incentive plans that would have vested prior to or upon the change in control will become vested on the change in control date, and the exercise period of such equity awards, and other equity awards held by the participant that otherwise would have expired, will be extended to the later of (i) thirty days following the first date after a change in control in which the shares underlying the equity award may be traded, and (ii) the permitted exercise date in the plan or grant assuming the change in control happened immediately prior to the participant's termination. However, in no event will any stock option or other equity award be extended (i) beyond the expiration date of the grant, or (ii) such that the grant will be subject to the additional tax under Section 409A of the Internal Revenue Code.

In the event that a participant would become subject to a "golden parachute" excise tax under Section 4999 of the Internal Revenue Code as a result of severance benefits and payments, the severance benefits and payments owed to the participant shall be reduced to an amount one dollar less than the amount that would subject the participant to the excise tax, unless the total severance benefits/payments net of the excise taxes are greater than the amount that the participant would receive following any such reduction.

Change in Control Severance Plan

Each of the NEOs, other than our CEO, participates in our change in control severance plan that was adopted by the board of directors on January 20, 2006. The purposes of the plan are (i) to help us retain key employees, (ii) to help maintain the focus of such employees on our business and to mitigate the distractions caused by the possibility that we may be the target of an acquisition, and (iii) to provide certain benefits to such employees in the event their employment is terminated (or constructively terminated) after, or in contemplation of, a change in control. On November 14, 2008, the change in control severance plan was amended and restated to bring it into compliance with Section 409A of the Internal Revenue Code (“Section 409A”).

Under the plan, each participant is entitled to receive a cash severance payment in an amount equal to one, or, in designated cases, including with respect to the NEOs other than Dr. Schleifer, two times the sum of the participant’s annual base salary and his or her average annual cash incentive over the prior three years if, within two years after or 180 days before a change in control, either the participant resigns his or her employment for Good Reason (as defined in the plan) or the participant’s employment is terminated by the Company for any reason other than Cause (as defined in the plan). This amount will be paid in a lump-sum severance payment. A participant so terminated is also entitled to receive a pro-rata annual cash incentive for the year in which he or she is terminated based on the portion of the year the participant was employed by us. In addition, for either one or two years, as the case may be, plan participants will receive continuation of health care coverage and welfare benefits provided by us, to the extent permitted by our benefit plans, at a cost no greater than what the participant’s cost would have been if he or she had continued his or her employment with the Company.

In the event that a plan participant resigns his or her employment for Good Reason (which generally conforms to the definition in Section 409A), or the participant’s employment is terminated by the Company for any reason other than Cause, in either case within two years after or 180 days before a change in control, then, unless otherwise provided in an award agreement, the participant’s stock options and other equity awards granted under our long-term incentive plans that would have vested prior to or upon the change in control will become vested on the change in control date, and the exercise period of such equity awards, and other equity awards held by the participant that otherwise would have expired, will be extended to the later of (i) 30 days following the first date after a change in control in which the shares underlying the equity award may be traded, and (ii) the permitted exercise date in the plan or grant assuming the change in control happened immediately prior to the participant’s termination. However, in no event will any stock option or other equity award be extended (i) beyond the expiration date of the grant, or (ii) such that the grant will be subject to the additional tax under Section 409A of the Internal Revenue Code.

In the event that a participant would become subject to a “golden parachute” excise tax under Section 4999 of the Internal Revenue Code as a result of severance benefits and payments, the severance benefits and payments owed to the participant shall be reduced to an amount one dollar less than the amount that would subject the participant to the excise tax, unless the total severance benefits/payments net of the excise taxes are greater than the amount that the participant would receive following any such reduction.

The following table shows the potential payments to our NEOs (other than our CEO), upon their hypothetical termination (other than for Cause) or resignation for Good Reason, in the two years following, or the six months prior to, a change in control. The information in the table below assumes an effective termination or resignation date of December 31, 2020 and is further based on the assumptions set forth in the footnotes to the table; actual values and amounts may differ from those presented below.

ADDITIONAL COMPENSATION INFORMATION

ANNUAL CASH INCENTIVES

In 2016, we adopted our Cash Incentive Bonus Plan for purposes of allowing our annual cash incentives to qualify as performance-based compensation under Section 162(m) of the Internal Revenue Code and permitting us to deduct cash incentive compensation that might otherwise not be deductible by reason of Section 162(m) (as then in effect). Although the Tax Cuts and Jobs Act eliminated the performance-based compensation exception for compensation paid in 2018 and beyond (as discussed under “Compensation Processes—Tax Implications” above), we have continued to use the Cash Incentive Bonus Plan for annual cash incentives for the reasons discussed under “Compensation Discussion and Analysis—Our Compensation Philosophy and Objectives” above. For 2020 annual cash incentives for the NEOs, in March 2020 the Compensation Committee set up a cash incentive pool under the Cash Incentive Bonus Plan; specified maximum allocations of such pool to the NEOs and certain other senior executives; and established a R&D-related performance goal consisting of (i) the submission of one or more Investigational New Drug Applications, Biologics License Applications, or supplemental Biologics License Applications with the FDA (or its equivalent outside the United States) or (ii) the approval of any regulatory filing of the type described in clause (i) by the FDA or the applicable regulatory authority outside the United States. In November 2020, the Compensation Committee determined that Regeneron’s performance in 2020 exceeded the established goal, thus enabling the funding of the cash incentive pool, and awarded Drs. Schleifer and Yancopoulos and Messrs. Landry and Van Plew their respective maximum allocations of the 2020 cash incentive pool; such allocations were less than the cash incentive amounts that would have resulted from applying the Company performance multiplier for 2020 and applicable personal performance multiplier for 2020 to such NEOs’ respective target cash incentive amounts. In the case of Dr. Murphy, the Compensation Committee exercised “negative discretion” (as permitted under the Plan) to reduce his maximum allocation of the 2020 cash incentive pool to equal an amount determined by applying the Company performance multiplier for 2020 and his personal performance multiplier for 2020 to his target cash incentive amount.

The targets for the 2020 annual cash incentives for the NEOs were set as percentages of their respective base salaries as follows: Dr. Schleifer—120%; Dr. Yancopoulos—120%; Mr. Landry—65%; Mr. Van Plew—65%; and Dr. Murphy��65%.

For 2020, Dr. Schleifer’s target cash compensation was set approximately at the median of the Peer Group. In determining the cash incentive target for Dr. Yancopoulos, the Compensation Committee took into consideration the importance of his scientific leadership as President & CSO and the significant contributions he has made to the success of the Company and, specifically, to the discovery and development of the Company’s commercial products, its pipeline of internally developed product candidates, and its platform technologies. The Compensation Committee determined that there were no meaningful comparative data for Dr. Yancopoulos relating to similarly situated executives and that his base salary and cash incentive for 2020 would be set at 85% of Dr. Schleifer’s. In determining the cash incentive targets for 2020 for Messrs. Landry and Van Plew and Dr. Murphy, the Compensation Committee took into consideration the compensation of similarly situated executive officers at companies in the Peer Group.

The cash incentives were determined through the use of both an individual and a Company performance component with a range of 0 to 1.5 for the personal performance multiplier and a range of 0 to 2.0 for the Company performance multiplier (which was increased to 2.25 in 2020 as discussed below), depending upon performance during the year. Both the personal performance multiplier and the Company performance multiplier were determined by the Compensation Committee for each NEO based on the Committee’s assessment of the Company’s performance relative to the general corporate goals described below and, in the case of each of Messrs. Landry and Van Plew and Dr. Murphy, the NEO’s personal performance during the year.

With respect to 2020, the Compensation Committee set the Company performance multiplier at 2.25. In exceeding the range historically used for annual cash incentive awards (0 to 2.0), the Compensation Committee recognized the significant accomplishments in all key areas of Regeneron’s business despite the impact of the COVID-19 pandemic;

Corporate Governance Aspects92   /   2021 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING

COMPENSATION-RELATED MATTERS / COMPENSATION DASHBOARD

the Company’s progress with its novel investigational cocktail REGEN-COV achieved in 2020; and the extraordinary efforts and performance of Company employees in 2020. For more information on these and other factors that contributed most to the Compensation Committee’s determination of the Company performance multiplier in 2020, see the subsection “Compensation Discussion and Analysis—Components of Executive Pay: What We Pay and Why We Pay It—Annual Cash Incentives.”

With respect to 2020, the Compensation Committee approved a personal performance multiplier of 1.5 for each of Messrs. Landry and Van Plew and Dr. Murphy. The personal performance component accounted for 40% of these NEOs’ cash incentives. The Company component was based on a Company performance multiplier that was determined based on the Company’s overall corporate performance (as described above) against 2020 goals that were approved by the board of directors in January 2020. This Company performance component accounted for 60% of the cash incentives awarded to Messrs. Landry and Van Plew and Dr. Murphy. In the case of Drs. Schleifer and Yancopoulos, the Compensation Committee focused exclusively on overall Company performance in 2020 (as described above) when determining their cash incentives and did not utilize a personal performance multiplier. As noted above, in each case where the 2020 annual cash incentive calculation would have resulted in an NEO earning a cash incentive in excess of the maximum amount previously allocated to such executive by the Compensation Committee in March 2020 under our Cash Incentive Bonus Plan, the 2020 cash incentive was capped at such maximum amount.

In determining the personal performance multiplier for Mr. Landry, the Compensation Committee gave special consideration to Mr. Landry’s leadership of and accomplishments in the Company’s accounting, finance, and tax functions and across his other responsibilities, including his leadership of several significant transactions in 2020 that delivered value to shareholders and strengthened the Company’s capital structure. In the case of Mr. Van Plew, the Compensation Committee focused primarily on Mr. Van Plew’s leadership of and accomplishments in the Company’s Industrial Operations and Product Supply organization, including with respect to expanded/relocated manufacturing capacities and preparations for new product launches (including, in each case, with respect to REGEN-COV) as well as the successful completion of all regulatory audits concerning the Company’s manufacturing practices in 2020. In the case of Dr. Murphy, the Compensation Committee considered the progress and continued expansion of the Company’s research and preclinical development pipeline, including the rapid discovery of REGEN-COV, as summarized in the subsection “Compensation Discussion and Analysis—Components of Executive Pay: What We Pay and Why We Pay It—Annual Cash Incentives.”

PERQUISITES AND PERSONAL BENEFITS

All employees who participate in our 401(k) Savings Plan, including the NEOs, are eligible to receive certain matching contributions. In each plan year, we contribute to each participant’s account a matching contribution (in the form of shares of our common stock) equal to 50% of a specified percentage of the participant’s compensation that the participant has contributed to the plan (which was 8% with respect to 2018 and 10% with respect to 2019 and 2020), up to a maximum level established under the Internal Revenue Code. Each of our NEOs participated in our 401(k) Savings Plan during 2020 and received matching contributions in the aggregate amount of $13,000 ($9,750 in the case of Mr. Van Plew) in the form of shares of our common stock. The contributions were paid quarterly (with the contribution in respect of the fourth quarter of 2020 paid in February 2021) and are included in the compensation amounts reported for each of our NEOs in the Summary Compensation Table included in this proxy statement. As with all employees, the number of shares of common stock that each NEO received on a quarterly basis was determined using the average market price per share of our common stock during the applicable quarter.

To achieve increased efficiencies and a more secure traveling environment, the Company provides air transportation for certain executive and director travel in accordance with guidelines approved by our board of directors. Based on the recommendation of an independent, third-party security study, the guidelines and our security policy require Drs. Schleifer and Yancopoulos (as well as their spouses and children when they accompany them) to use, as much as practicable, Company-provided aircraft for all business and personal air travel. Regeneron covers the cost of any such personal air travel for up to $250,000 in incremental cost (as described below) annually for each of Drs. Schleifer and Yancopoulos. Family members or other guests may accompany our NEOs and directors during Company-provided air business travel, space permitting, so long as they cover any incremental cost related to such guests (other than

2021 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING   /   93

COMPENSATION-RELATED MATTERS   /   COMPENSATION DASHBOARD

with respect to the family members of Drs. Schleifer and Yancopoulos as described above). In addition, in limited circumstances personal use of Company-provided air travel by our other NEOs or directors may be permitted if authorized by the Chairman and any incremental cost is paid by the lead passenger. Any required reimbursement or other payment of the incremental cost is made to the extent permitted by applicable Federal Aviation Administration rules.

We determine the incremental cost of any Company-provided personal or guest air travel based on the direct variable operating cost. Items included in the calculation include (as applicable) fuel costs; landing, non-home-base hangar or aircraft parking, and ground handling fees; in-flight catering; travel, lodging, and other expenses for flight crew; and other trip-related variable cost, including the use of our fractional jet interests. Because Company-provided air transportation is used primarily for business travel, incremental costs exclude fixed costs that generally do not change based on usage, such as (as applicable) flight crew salaries; aircraft purchase or lease costs; depreciation; insurance costs; certain maintenance fees based on minimum usage; and home-base hangar costs. When the aircraft is already flying to a destination for business purposes, only the direct variable costs associated with the guest (for example, catering), if any, are included in determining the aggregate incremental cost to Regeneron. If any aircraft flies empty before picking up or after dropping off a passenger for personal reasons, this “deadhead” segment would be included in the aggregate incremental cost based on the methodology described above. The amount of disallowed corporate tax deductions attributable to Company-provided personal and guest air travel is not included in the NEO incremental cost calculation.

The security policy also covers secure car transportation, on-site residential security at the primary residence for each of Drs. Schleifer and Yancopoulos, and, starting in November 2020, 24/7 personal security services for Drs. Schleifer and Yancopoulos. The addition of 24/7 personal security services for these executives was approved by the board of directors and the Compensation Committee in November 2020 based on the recommendation of an independent, third-party security study. For 2020, we calculated the incremental costs of the 24/7 personal security services based on the amounts paid by the Company to the third-party provider of such services; and calculated the incremental costs of the secure car transportation and on-site residential security based on the average fuel cost per mile times total miles traveled in connection with such services plus any overtime employee wages attributable to such services. Because Company-provided car transportation is primarily used for business travel, the incremental costs for 2020 excluded ordinary wages, taxes, and benefits of the drivers, who are full-time employees of the Company, as well as fixed lease costs and routine maintenance that would have been incurred in any event.

Amounts associated with personal or guest Company-provided air and secure car transportation/personal and residential security services are imputed as income to the NEOs to the extent required by applicable tax regulations. The NEOs do not receive a tax gross-up from us to cover their personal income tax obligations in respect of any such imputed income.

The amounts disclosed in the “All other compensation” column of the Summary Compensation Table relating to personal and guest use of Company-provided air transportation, secure car transportation, and personal and residential security services in accordance with our security policy attributable to Drs. Schleifer and Yancopoulos are based on the incremental cost resulting from such transportation/services as described above.

The Corporate Governance and Compliance Committee monitors business and any personal or guest Company-provided air travel on a periodic basis.

Additional information regarding perquisites and other personal benefits provided to our NEOs in, or with respect to, 2020 is given in the applicable footnotes to the Summary Compensation Table included in this proxy statement.

POTENTIAL SEVERANCE PAYMENTS

Except for equity award agreements for Dr. Vagelos and the 2020 PSU award agreements,9 outstanding equity award agreements for all employees include a “double trigger” provision for the acceleration of vesting of unvested equity awards upon a termination by the Company without cause or by the employee for good reason within two years following a change in control. Dr. Vagelos’s stock option, PSU, and RSU awards contain change-of-control provisions consistent with those applicable to the non-employee director equity awards, as described under “Corporate Governance – Compensation of Directors” above.

Our CEO has an employment agreement that provides for certain severance benefits following termination, including following death or disability, resignation following defined “good reason” events, or termination in connection with a change in control. The other NEOs are covered by a change in control severance plan, which provides certain benefits to them and other designated officers if they are terminated in connection with a change in control. In addition, in the case of our CSO, stock option, RSA, and PSU award agreements applicable to his awards granted since December 2015 provide that he would have a “good reason” for terminating his employment with Regeneron upon or within two years after the occurrence of a change in control if the employment of our CEO has ended due to our CEO’s involuntary termination (as defined in the CEO’s employment agreement). Information regarding applicable payments under this employment agreement and change in control severance plan is provided in the subsection “2020 Compensation Tables—Post-Employment Compensation.”

Our NEOs will forfeit any unvested stock options or RSAs upon the termination of their employment for any reason (including disability or retirement) other than death, except as provided in our employment agreement with our CEO, in our change in control severance plan, and in certain stock option agreements with our CSO. In the event of the death of an employee, any unvested stock options held by such employee become immediately exercisable, and any shares subject to RSAs/RSUs will become fully vested. In the case of PSU awards to our CEO and CSO (as well as the 2019 PSU award to Dr. Vagelos), upon a termination of employment due to death (or, in the case of 2020 PSU awards, also disability), the PSU award will remain outstanding, and any vesting of the PSUs will be determined following the completion of the applicable performance period. For information regarding the value of accelerated stock options, RSAs, and PSUs held by our CEO and other NEOs (as applicable) as of December 31, 2020, see the subsection “2020 Compensation Tables—Post-Employment Compensation” under “Value of Accelerated Stock Options/PSUs” in the table entitled “Potential Severance Payments under Dr. Schleifer’s Employment Agreement” (for our CEO) and under “Value of Accelerated Stock Options/RSAs/PSUs” in the table entitled “Potential Payments under Change in Control Severance Plan” (for other NEOs).

Except as provided below, when employees retire, they forfeit all unvested stock options, RSAs, and PSUs, including the PSUs granted to our CEO and CSO in 2020. An employee considered “retirement eligible” upon separation under our employee policies as in effect from time to time has the remaining life of the 10-year stock option term to exercise stock options that are vested as of the date of his or her retirement. In addition, in the case of (i) stock option award agreements with our CEO (as provided in his employment agreement) and, commencing in December 2018, our CSO and Dr. Vagelos and (ii) the 2019 PSU award agreements with our CEO and CSO and Dr. Vagelos, awards thereunder will continue to vest in accordance with the terms of the applicable award agreement so long as they are “retirement eligible” upon separation.

The award agreements for the 2020 PSU awards to our CEO and CSO provide that if the recipient’s employment with the Company is terminated without Cause or the recipient leaves his employment with the Company for a Good Reason (each as defined in or incorporated by reference into the Second Amended and Restated Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan or the award agreement), earnout is measured as of termination and all PSUs earned as of that date vest and remain subject to the Holding Period. See “Compensation Discussion and Analysis—Components of Executive Pay: What We Pay and Why We Pay It—Annual Equity Awards” for more information.

The Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan (referredPSUs granted to our CEO and CSO in this subsection2020, if there is a change in control, earnout is measured as of the date of the change in control (using the applicable transaction price as the "Plan") isending stock price), and all PSUs earned as of that date vest with no Holding Period and any unearned PSUs are forfeited immediately. In the only plan currently usedcase of the PSUs granted to our CEO and CSO in 2019, if any PSUs vest upon a change of control (as a result of performance exceeding the relevant TSR goal for the period from the date of grant to the date of the change of control), the shares earned will be delivered upon the earlier of (a) a termination by the Company to grant equity awards. It has been designed to include a numberwithout cause or by the employee for good reason (in each case within two years following the change in control) and (b) the fifth year anniversary of provisions that promote best practices by reinforcing the alignment

between equity compensation arrangements for eligible employees and non-employee directors, on the one hand, and shareholders' interests, on the other hand. These provisions include:


Provision





Description

No Discounted Stock OptionsStock options are not granted with an exercise price less than the fair market value of common stock (as defined in the Plan) on the date of grant.
No Stock Option Re-pricing or ExchangeExcept for equitable adjustments in connection with specific corporate transactions (such as stock splits, recapitalizations, reorganizations, mergers, consolidations, and similar transactions), the Plan does not permit a decrease in the exercise price of a stock option granted under the Plan through settlement, cancellation, forfeiture, exchange, surrender, or otherwise below the fair market value of common stock (as defined in the Plan) on the date of grant.

2021 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING   /   95
Minimum Vesting Requirements If the vesting condition for any equity award (other than an option or a stock appreciation right) made to an employee is based solely upon continued employment, the regular vesting may not be more favorable to the employee than in equal annual increments over 36 months.

If the vesting condition for any equity award (other than an option or a stock appreciation right) made to an employee is based upon the attainment of specified performance measures, the regular performance vesting period may not be less than one year.

The Compensation Committee's discretion to deviate from the minimum vesting requirements described above is limited to accelerated vesting upon a change of control or upon a termination of the employee's employment and with respect to grants not in excess of 1,000,000 shares in the aggregate under the Plan.

Recoupment PolicyAwards granted to our officers and other specified employees under the Plan are subject to recoupment or reduction in accordance with the terms of our policy regarding recoupment or reduction of incentive compensation.
Independent AdministrationThe Plan is administered by the Compensation Committee, which is intended to be comprised solely of non-employee directors each of whom meets the additional independence criteria applicable to compensation committee members under the listing standards of The NASDAQ Stock Market LLC, qualifies as a "Non-Employee Director" pursuant to Rule 16b-3 under the Exchange Act, and meets the requirements for an "outside director" within the meaning of Section 162(m) of the Internal Revenue Code.

COMPENSATION-RELATED MATTERS   /   COMPENSATION DASHBOARD

The change-in-control severance benefits provided to our NEOs are designed to promote stability and continuity of our senior management and are intended to preserve employee morale and productivity and encourage retention in the face of the disruptive impact of an actual, threatened, or rumored change in control of the Company. These severance benefits were established following a review of comparable practices at the Company’s peer companies and with the advice of the Compensation Committee’s consultant.

We have no pension, deferred compensation, or retirement plans applicable to our NEOs, other than our 401(k) Savings Plan described above.

PAY RATIO

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are required to disclose the median of the annual total compensation of our employees (excluding our principal executive officer), the annual total compensation of our principal executive officer, Dr. Schleifer, and the ratio of these two amounts.

We have determined the total compensation of our median employee (based on the 2020 annual total compensation of our employees, excluding Dr. Schleifer) to be $145,019. The total 2020 compensation of Dr. Schleifer, as reported in the Summary Compensation Table above and including the five-year, front-loaded PSU award granted to Dr. Schleifer in 2020 in lieu of five years of annual equity awards (i.e., until the Company’s regular year-end grant cycle in December 2025), was $135,350,121. Accordingly, the ratio of the 2020 annual total compensation of Dr. Schleifer to the median of the 2020 annual total compensation of our employees was approximately 933 to 1. This ratio would have been approximately 216 to 1 if the 2020 PSU award were annualized. See “Compensation Discussion and Analysis—Components of Executive Pay: What We Pay and Why We Pay It—Annual Equity Awards” for more information regarding this PSU award.

For 2020 we identified the median employee as of December 31, 2020 by (i) aggregating for each applicable employee (a) annual base salary for salaried employees (or wages plus overtime, based on annual work schedule, for permanent hourly employees), (b) the target annual cash incentive, and (c) the grant date fair value of any equity awards granted during 2020, and (ii) ranking this compensation measure from lowest to highest. This calculation was performed for all employees, excluding Dr. Schleifer, whether employed on a full-time, part-time, or seasonal basis. For purposes of identifying the median employee, we converted amounts paid in foreign currencies to U.S. dollars based on the applicable 2020 average exchange rate. This process resulted in the identification of an employee whose 2020 compensation was significantly higher than that of adjacent employees. As a result, we substituted an alternate employee, whose compensation was consistent with that of surrounding employees near the median, identified as discussed above.

We believe that the pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our internal records and the methodology described above. Because the SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates, and assumptions in calculating their own pay ratios.

The Plan provides for the vesting of shares as determined by the Compensation Committee; should the Company's relationship with a Plan participant terminate before all shares are vested, unvested shares will be repurchased by the Company at a price per share equal to the original amount paid by the Plan participant. As of December 31, 2015,2020, there were no unvested shares and 44,246 shares of Class A stock available for future grants under the Plan.

98   /   2021 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING

WHEN ARE SHAREHOLDER PROPOSALS DUE FOR THE 2022 ANNUAL MEETING OF SHAREHOLDERS?

A shareholder wishing to present a proposal at the 2022 Annual Meeting of Shareholders must submit the proposal in writing and it must be received by the Company at its principal executive offices at 777 Old Saw Mill River Road, Tarrytown, New York 10591-6707 by December 24, 2021, and must satisfy the other conditions established by the SEC, in order for such proposal to be considered for inclusion in the Company’s proxy statement and form of proxy relating to that meeting.

Under our Amended and Restated By-Laws, proposals of shareholders intended to be submitted for a formal vote (other than proposals to be included in our proxy statement) at the 2022 Annual Meeting may be made only by a shareholder of record who has given notice of the proposal to the Secretary of the Company at our principal executive offices no earlier than 90 days and no later than 60 days prior to the meeting; provided that if less than 70 days’ notice or public disclosure of the date of the 2022 Annual Meeting is given or made to shareholders, notice by the shareholder in order to be timely must be received no later than the close of business on the tenth day following the day on which such notice of the annual meeting was first mailed or such public disclosure of the annual meeting was made, whichever first occurs. The notice must contain certain information as specified in our Amended and Restated By-Laws. Assuming our 2022 Annual Meeting is held on June 10, 2022 in accordance with the Company’s past practice, and at least 70 days’ notice or prior public disclosure of the date of the 2022 Annual Meeting is given or made to shareholders, notice of such proposals would need to be given no earlier than March 12, 2022 and no later than April 11, 2022. Any proposal received outside of such dates will not be considered “timely” under the federal proxy rules for purposes of determining whether we may use discretionary authority to vote on such proposal.

WHAT HAPPENS IF MULTIPLE SHAREHOLDERS SHARE AN ADDRESS?

Applicable rules permit brokerage firms and the Company to send one Notice of Internet Availability of Proxy Materials (or one annual report, proxy statement, and Notice of Internet Availability of Proxy Materials in the case of shareholders who have elected to receive paper copies of our proxy materials) to multiple shareholders who share the same address under certain circumstances. This practice is known as “householding.” We believe that householding will provide greater convenience for our shareholders, as well as cost savings for us, by reducing the number of duplicate documents that are sent to your home. Consequently, we have implemented the practice of householding for shares held in “street name” and intend to deliver only one copy of the applicable proxy materials to multiple shareholders sharing the same address. If you wish to receive separate copies of the proxy statement for the 2021 Annual Meeting, the 2020 Annual Report, or the Notice of Internet Availability of Proxy Materials, you may find these materials at our internet website (www.regeneron.com) or you may stop householding for your account and receive separate printed copies of these materials by contacting our Investor Relations Department, at Regeneron Pharmaceuticals, Inc., 777 Old Saw Mill River Road, Tarrytown, New York 10591-6707, or by calling us at 914-847-7000, and these materials will be promptly delivered to you. If you hold shares registered in your name (sometimes called a shareholder of record), you can elect householding for your account by contacting us in the same manner described above. Any shareholder may stop householding for your account by contacting our Investor Relations Department at the address and/or phone number included above. If you revoke your consent, you will be removed from the householding program within 30 days of receipt of your revocation and each shareholder at your address will receive individual copies of our disclosure documents.

If any other matter is properly presented at the Annual Meeting upon which a vote may properly be taken, shares represented by duly executed and timely submitted proxies will be voted on any such matter in accordance with the judgment of the persons named as proxies in the enclosed proxy card. Discretionary authority for them to do so is contained in the enclosed proxy card.

HOW CAN YOU RECEIVE A PRINTED COPY OF THE COMPANY’S 2020 ANNUAL REPORT?

Interested shareholders may obtain without charge a copy of our 2020 Annual Report (without exhibits), which includes our audited financial statements for the fiscal year ended December 31, 2020, required to be filed with the SEC, by making a written request to Regeneron Pharmaceuticals, Inc., 777 Old Saw Mill River Road, Tarrytown, New York 10591-6707, Attention: Investor Relations, or by calling our Investor Relations Department at (914) 847-7000.

HOW DO YOU ELECT TO RECEIVE FUTURE PROXY MATERIALS ELECTRONICALLY?

If you previously requested to receive proxy materials through the mail, or by means of an e-mail with links to the proxy materials and the proxy voting website, your election will remain in effect until you revoke it. Shareholders currently receiving paper copies of our proxy materials, and shareholders who received a paper copy of the Notice of Internet Availability of Proxy Materials, may instead elect to receive all future proxy materials electronically through an e-mail with a link to these documents on the Internet. Receiving these documents online conserves resources, saves the Company the cost of producing and mailing documents to your home or business, and gives you an automatic link to the proxy voting site.

If your shares are registered in your name or you hold shares in the Company Stock Fund in the Company’s 401(k) Savings Plan, to enroll in the electronic delivery service, vote your shares through the Internet at www.proxyvote.com and, when prompted, indicate that you agree to receive or access shareholder communications electronically in future years. If your shares are not registered in your name, to enroll in the electronic delivery service, check the information provided to you by your bank or broker, or contact your bank or broker for instructions on how to elect to view future proxy statements and annual reports over the Internet.

A more complete description of these and other material risks can be found in Regeneron’s filings with the U.S. Securities and Exchange Commission, including its Form 10-K for the fiscal year ended December 31, 2020, including in the section thereof captioned “Item 1A. Risk Factors.” Any forward-looking statements are made based on management’s current beliefs and judgment, and the reader is cautioned not to rely on any forward-looking statements made by Regeneron. Regeneron does not undertake any obligation to update (publicly or otherwise) any forward-looking statement, whether as a result of new information, future events, or otherwise.

This proxy statement uses non-GAAP net income and non-GAAP net income per share, which are financial measures that are not calculated in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). These non-GAAP financial measures are computed by excluding certain non-cash and other items from the related GAAP financial measure. Non-GAAP adjustments also include the estimated income tax effect of reconciling items. The Company makes such adjustments for items the Company does not view as useful in evaluating its operating performance. For example, adjustments may be made for items that fluctuate from period to period based on factors that are not within the Company's control (such as the Company's stock price on the dates share-based grants are issued) or items that are not associated with normal, recurring operations (such as changes in applicable laws and regulations). Management uses these non-GAAP measures for planning, budgeting, forecasting, assessing historical performance, and making financial and operational decisions, and also provides forecasts to investors on this basis. Additionally, such non-GAAP measures provide investors with an enhanced understanding of the financial performance of the Company's core business operations. However, there are limitations in the use of these and other non-GAAP financial measures as they exclude certain expenses that are recurring in nature. Furthermore, the Company's non-GAAP financial measures may not be comparable with non-GAAP information provided by other companies. Any non-GAAP financial measure presented by Regeneron should be considered supplemental to, and not a substitute for, measures of financial performance prepared in accordance with GAAP. A reconciliation of the Company's historical GAAP to non-GAAP results is included below.

2021 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING   /   103

 

2021 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING

When are shareholder proposals due for the 2017 Annual Meeting of Shareholders?

A shareholder wishing to present a proposal at the 2017 Annual Meeting of Shareholders must submit the proposal in writing and it must be received by the Company at its principal executive offices at 777 Old Saw Mill River Road, Tarrytown, New York 10591-6707 by December 28, 2016, and must satisfy the other conditions established by the SEC, in order for such proposal to be considered for inclusion in the Company's proxy statement and form of proxy relating to that meeting.

Under our by-laws, proposals of shareholders intended to be submitted for a formal vote (other than proposals to be included in our proxy statement) at the 2017 Annual Meeting may be made only by a shareholder of record who has given notice of the proposal to the Secretary of the Company at our principal executive offices no earlier than 90 days and no later than 60 days prior to the meeting; provided that if less than 70 days' notice or public disclosure of the date of the 2017 Annual Meeting is given or made to shareholders, notice by the shareholder in order to be timely must be received no later than the close of business on the tenth day following the day on which such notice of the annual meeting was first mailed or such public disclosure of the annual meeting was made, whichever first occurs. The notice must contain certain information as specified in our by-laws. Assuming our 2017 Annual Meeting is held on June 9, 2017 in accordance with the Company's past practice, and at least 70 days' notice or prior public disclosure of the date of the 2017 Annual Meeting is given or made to shareholders, notice of such proposals would need to be given no earlier than March 11, 2017 and no later than April 10, 2017. Any proposal received outside of such dates will not be considered "timely" under the federal proxy rules for purposes of determining whether we may use discretionary authority to vote on such proposal.

What happens if multiple shareholders share an address?

Applicable rules permit brokerage firms and the Company to send one Notice of Internet Availability of Proxy Materials (or one annual report, proxy statement, and Notice of Internet Availability of Proxy Materials in the case of shareholders who have elected to receive paper copies of our proxy materials) to multiple shareholders who share the same address under certain circumstances. This practice is known as "householding." We believe that householding will provide greater convenience for our shareholders, as well as cost savings for us by reducing the number of duplicate documents that are sent to your home. Consequently, we have implemented the practice of householding for shares held in "street name" and intend to deliver only one copy of the applicable proxy materials to

multiple shareholders sharing the same address. If you wish to receive separate copies of the proxy statement for the 2016 Annual Meeting, the 2015 Annual Report, or the Notice of Internet Availability of Proxy Materials, you may find these materials at our internet website (www.regeneron.com) or you may stop householding for your account and receive separate printed copies of these materials by contacting our Investor Relations Department, at Regeneron Pharmaceuticals, Inc., 777 Old Saw Mill River Road, Tarrytown, New York 10591-6707, or by calling us at 914-847-7000, and these materials will be promptly delivered to you. If you hold shares registered in your name (sometimes called a shareholder of record), you can elect householding for your account by contacting us in the same manner described above. Any shareholder may stop householding for your account by contacting our Investor Relations Department at the address and/or phone number included above. If you revoke your consent, you will be removed from the householding program within 30 days of receipt of your revocation and each shareholder at your address will receive individual copies of our disclosure documents.

Are there any other matters to be addressed at the Annual Meeting?

We know of no other matters to be brought before the Annual Meeting, except as set forth in this proxy statement. If any other matter is properly presented at the Annual Meeting upon which a vote may properly be taken, shares represented by duly executed and timely submitted proxies will be voted on any such matter in accordance with the judgment of the persons named as proxies in the enclosed proxy card. Discretionary authority for them to do so is contained in the enclosed proxy card.

Who will pay the costs related to this proxy statement and the Annual Meeting?

The solicitation of proxies is being made on behalf of the Company and we will bear the costs of the solicitation. We will be responsible for paying for all expenses to prepare, print, and mail the proxy materials to shareholders. In accordance with the regulations of the SEC, we will make arrangements with brokerage houses and other custodians, nominees, and fiduciaries to send proxies and proxy materials to their principals and will reimburse them for their reasonable expenses in so doing. In addition to the solicitation by use of the mails and the Internet, certain of our officers, directors, and employees may solicit the return of proxies by telephone, e-mail or personal interviews.

How can you receive a printed copy of the Company's 2015 Annual Report?

Interested shareholders may obtain without charge a copy of our 2015 Annual Report (without exhibits), which includes our audited financial statements for the fiscal year ended December 31, 2015, required to be filed with the SEC, by making a written request to Regeneron Pharmaceuticals, Inc., 777 Old Saw Mill River Road, Tarrytown, New York 10591-6707, Attention: Investor Relations, or by calling our Investor Relations Department at (914) 847-7000.

How do you elect to receive future proxy materials electronically?

If you previously requested to receive proxy materials through the mail, or by means of an e-mail with links to the proxy materials and the proxy voting website, your election will remain in effect until you revoke it. Shareholders currently receiving paper copies of our proxy materials, and shareholders who received a paper copy of the Notice of Internet

Availability of Proxy Materials, may instead elect to receive all future proxy materials electronically through an e-mail with a link to these documents on the Internet. Receiving these documents online conserves resources, saves the Company the cost of producing and mailing documents to your home or business, and gives you an automatic link to the proxy voting site.

If your shares are registered in your name or you hold shares in the Company Stock Fund in the Company's 401(k) Savings Plan, to enroll in the electronic delivery service, vote your shares through the Internet atwww.proxyvote.com and, when prompted, indicate that you agree to receive or access shareholder communications electronically in future years. If your shares are not registered in your name, to enroll in the electronic delivery service, check the information provided to you by your bank or broker, or contact your bank or broker for instructions on how to elect to view future proxy statements and annual reports over the Internet.

Appendix A  Note Regarding Forward-Looking Statements andNon-GAAP Financial Measures

This proxy statement includes forward-looking statements that involve risks and uncertainties relating to future events and the future performance of Regeneron Pharmaceuticals, Inc. ("we," "us," "our," "Regeneron," or the "Company"), and actual events or results may differ materially from these forward-looking statements. Words such as "anticipate," "expect," "intend," "plan," "believe," "seek," "estimate," variations of such words and similar expressions are intended to identify such forward-looking statements, although not all forward-looking statements contain these identifying words. These statements concern, and these risks and uncertainties include, among others, the nature, timing, and possible success and therapeutic applications of our products, product candidates, and research and clinical programs now underway or planned, including without limitation EYLEA® (aflibercept) Injection, Praluent® (alirocumab) Injection, sarilumab, dupilumab, fasinumab, REGN 2222, and the immuno-oncology program; unforeseen safety issues resulting from the administration of products and product candidates in patients, including serious complications or side effects in connection with the use of our product candidates in clinical trials; the likelihood and timing of possible regulatory approval and commercial launch of our late-stage product candidates and new indications for marketed products, including without limitation EYLEA®, Praluent®, sarilumab, dupilumab, fasinumab, and REGN 2222; ongoing regulatory obligations and oversight impacting our marketed products (such as EYLEA® and Praluent®), research and clinical programs, and business, including those relating to patient privacy; determinations by regulatory and administrative governmental authorities which may delay or restrict our ability to continue to develop or commercialize our products and product candidates; competing drugs and product candidates that may be superior to our products and product candidates; uncertainty of market acceptance and commercial success of our products and product candidates; our ability to manufacture and manage supply chains for multiple products and product candidates; coverage and reimbursement determinations by third-party payers, including Medicare and Medicaid; unanticipated expenses; the costs of developing, producing, and selling products; our ability to meet any of its sales or other financial projections or guidance and changes to the assumptions underlying those projections or guidance; the potential for any license or collaboration agreement, including our agreements with Sanofi and Bayer HealthCare LLC, to be cancelled or terminated without any further product success; and risks associated with third party intellectual property and

pending or future litigation relating thereto. A more complete description of these and other material risks can be found in our filings with the Securities and Exchange Commission, including our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 (filed with the Securities and Exchange Commission on February 11, 2016), including in the section thereof captioned "Item 1A. Risk Factors." Any forward-looking statements are made based on management's current beliefs and judgment, and the reader is cautioned not to rely on any forward-looking statements made by Regeneron. We do not undertake any obligation to update publicly any forward-looking statement, including without limitation any financial projection or guidance, whether as a result of new information, future events, or otherwise.

This proxy statement uses non-GAAP net income, which is a financial measure that is not calculated in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"). We believe that the presentation of this non-GAAP measure is useful to investors because it excludes (i) non-cash share-based compensation expense, which fluctuates from period to period based on factors that are not within the Company's control, such as the Company's stock price on the dates share-based grants are issued; (ii) the incremental charge recorded in the third quarter of 2014 related to the issuance of the final IRS regulations that provide guidance on the annual fee imposed by the Patient Protection and Affordable Care Act (the final IRS regulations differed from the temporary regulations issued in 2011 which resulted in the recognition of a catch-up adjustment); (iii) non-cash interest expense related to the Company's convertible senior notes, since this is not deemed useful in evaluating the Company's operating performance; (iv) loss on extinguishment of debt, since this non-cash charge is based on factors that are not within the Company's control; and (v) income tax expense for 2014, which was principally a non-cash expense due primarily to utilization of net operating loss and tax credit carryforwards, and deductions related to employee stock option exercises. In 2015, income tax expense adjustments consider the tax effect of reconciling items and an adjustment from GAAP tax expense to the amount of taxes that are paid or payable in cash in respect of the current period. As there is a significant difference between the Company's effective tax rate and actual cash income taxes paid or payable, GAAP income tax expense is not deemed useful in evaluating the Company's operating performance. Management uses these non-GAAP measures for planning, budgeting, forecasting, assessing historical performance, and making financial

and operational decisions, and also provides forecasts to investors on this basis. However, there are limitations in the use of these and other non-GAAP financial measures as they exclude certain expenses that are recurring in nature. Furthermore, the Company's non-GAAP financial measures may not be comparable with non-GAAP information provided by other

companies. Any non-GAAP financial measure presented by Regeneron should be considered supplemental to, and not a substitute for, measures of financial performance prepared in accordance with GAAP. A reconciliation of our GAAP to non-GAAP results is included below.
