Dear Fellow Shareholders:

It is my pleasure to invite you to attend the 2015 Annual Meeting of Shareholders of Regeneron Pharmaceuticals, Inc. to be held on Friday, June 12, 2015 at 10:30 a.m., Eastern Time, at the Westchester Marriott Hotel, 670 White Plains Road, Tarrytown, New York 10591.

This year we are again using the "Notice and Access" method of providing proxy materials to you via the Internet. We believe that this process provides you with a convenient and quick way to access your proxy materials and vote your shares, while allowing us to reduce the costs of printing and distributing the proxy materials and conserve resources. On or about April 27, 2015, we will mail to our shareholders a Notice of Internet Availability of Proxy Materials containing instructions on how to access our proxy statement and our 2014 annual report and vote via the Internet. The Notice also contains instructions on how to receive a paper copy of the proxy materials and our 2014 annual report. Similar to last year, our proxy materials are presented in an enhanced format, with a Proxy Summary and an expanded Compensation Discussion and Analysis, which we hope will make your review of these materials easier.

One of the priorities of the board of directors and Company management is ensuring robust outreach and engagement with our shareholders. Over the last year, we have spent a significant amount of time speaking with some of our shareholders about executive compensation and corporate governance. These discussions were valuable because they allowed us to receive direct feedback from our shareholders and consider how we can improve. As a result of these discussions, we have implemented several changes to our executive compensation program and continued the implementation of our existing compensation and governance initiatives. We encourage you to read the Compensation Discussion and Analysis section of the proxy statement beginning on page 36 for details of our executive compensation program and these recent changes and initiatives.

Each of the Notice of Internet Availability of Proxy Materials that will be mailed and the Notice of Annual Meeting of Shareholders and proxy statement contained herein identifies the items we plan to address at the Annual Meeting. At the Annual Meeting, we will also present a brief report on the Company and our business and give you the opportunity to ask questions.

Your vote is important. Whether or not you plan to attend the Annual Meeting, you can cast your vote via the Internet or by telephone, or, if you receive paper copies of the proxy materials, by completing the accompanying proxy and returning it in the prepaid envelope provided. If you attend the Annual Meeting, you may vote in person if you wish, even if you previously submitted a proxy.

I look forward to seeing you on June 12^th.

Shares held as of the record date by holders who are present or represented by proxy at the Annual Meeting but who have abstained from voting or have not voted with respect to some or all of such shares on any proposal to be voted on at the Annual Meeting will be counted as present for purposes of establishing a quorum.

Overview

Regeneron is committed to good corporate governance, which we believe promotes the long-term interests of shareholders, strengthens the accountability of the board of directors

and management, and helps build trust in the Company. The following chart summarizes key information regarding our corporate governance.

*

As of April 16, 2015.

Procedures Relating to Nominees

The Corporate Governance and Compliance Committee will consider a nominee for election to the board of directors recommended by a shareholder of record if the shareholder submits the nomination in compliance with the requirements of our by-laws and the Guidelines Regarding Director Nominations, which are available on our website at www.regeneron.com under the "Corporate Governance" heading on the "Company" page.

In considering potential candidates for the board of directors, the Corporate Governance and Compliance Committee considers factors such as whether or not a potential candidate: (1) possesses relevant expertise; (2) brings skills and experience complementary to those of the other members of the board; (3) has sufficient time to devote to the affairs of the Company; (4) has demonstrated excellence in his or her field; (5) has the ability to exercise sound business judgment; (6) has the commitment to rigorously represent the long-term interests of the Company's shareholders; (7) possesses a diverse background and experience, including with respect to race, age, and gender; and (8) such other factors as the Corporate Governance and Compliance Committee may determine from time to time.

Candidates for director are reviewed in the context of the current composition of the board of directors, the operating requirements of the Company, and the long-term interests of

shareholders. In conducting the assessment, the Committee considers the individual's independence, experience, skills, background, and diversity, including with respect to race, age, and gender, along with such other factors as it deems appropriate, given the current needs of the board and the Company to maintain a balance of knowledge, experience, and capabilities. When recommending a slate of director nominees each year, the Corporate Governance and Compliance Committee reviews the current composition of the board of directors in order to recommend a slate of directors who, with the continuing directors, will provide the board with the requisite diversity of skills, expertise, experience, and viewpoints necessary to effectively fulfill its duties and responsibilities.

In the case of an incumbent director whose term of office is set to expire, the Corporate Governance and Compliance Committee reviews such director's overall service to the Company during the director's term and also considers the director's interest in continuing as a member of the board. In the case of a new director candidate, the Corporate Governance and Compliance Committee also reviews whether the nominee is "independent," based on our Corporate Governance Guidelines, applicable listing standards of the NASDAQ Stock Market LLC, and applicable SEC and other relevant rules and regulations, if necessary.

The Corporate Governance and Compliance Committee may employ a variety of methods for identifying and evaluating

16

Corporate Governance​

nominees for the board of directors. The Corporate Governance and Compliance Committee may consider candidates recommended by other directors, management, search firms, shareholders, or other sources. When conducting searches for new directors, the Corporate Governance and Compliance Committee will take reasonable steps to include diverse candidates in the pool of nominees and any search firm will affirmatively be instructed to seek to include diverse candidates. Candidates recommended by shareholders will be evaluated on the same basis as candidates recommended by our directors or management or by third party search firms or other sources. Candidates may be evaluated at regular or special meetings of the Corporate Governance and Compliance Committee.

Shareholder Rights to Remove Directors for Cause and to Call Special Shareholder Meeting

Regeneron's charter documents give shareholders the rights to (i) remove directors for cause by an affirmative vote of at least 80% of the outstanding shares of all classes of capital stock entitled to vote for directors; and (ii) call a special shareholder meeting upon the written request of at least 25% of the total number of votes entitled to be cast by shareholders.

Shareholder Communications with Directors

The Company has established a process for shareholders to send communications to the members of the board of directors. Shareholders may send such communications by mail addressed to the full board, a specific member or members of the board, or a particular committee of the board, at 777 Old Saw Mill River Road, Tarrytown, New York 10591-6707, Attention: Corporate Secretary. All such communications will be opened by our Corporate Secretary for the sole purpose of determining whether the contents represent a message to our directors. Any contents that are not in the nature of advertising,

promotions of a product or service, or patently offensive material will be forwarded promptly to the addressee. In the case of communications to the board or any individual director or group or committee of directors, the Corporate Secretary will make sufficient copies of the contents to send to such director or each director who is a member of the group or committee to which the envelope is addressed.

Board Committees

The board has a standing Audit Committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), a Compensation Committee, and a Corporate Governance and Compliance Committee, each of which is comprised entirely of independent directors. The Corporate Governance and Compliance Committee is responsible for reviewing and recommending for the board's selection candidates to serve on our board of directors and for overseeing all aspects of the Company's compliance program other than financial compliance. The board also has a standing Technology Committee. The board has adopted charters for the Audit Committee, Compensation Committee, Corporate Governance and Compliance Committee, and Technology Committee, current copies of which are available on our website at www.regeneron.com under the "Corporate Governance" heading on the "Company" page.

17

​ Corporate Governance​

We show below information on the membership, key functions, and number of meetings of each board committee during 2014. Effective April 4, 2014, Eric M. Shooter, Ph.D. retired as a

member of the board of directors and the Technology Committee, and Robert A. Ingram was elected as a member of the board of directors and the Compensation Committee.

18

Corporate Governance​

Code of Ethics

The board of directors has adopted a code of business conduct and ethics that applies to all of our employees, officers, and directors. You can find links to this code on our website at www.regeneron.com under the "Corporate Governance" heading on the "Company" page. We may satisfy the disclosure

requirement under Item 5.05 of Form 8-K regarding an amendment to, or a waiver from, a provision of our code of business conduct and ethics that applies to our principal executive officer, principal financial officer, principal accounting officer, or controller, or persons performing similar functions, by posting such information on our website where it is accessible through the same link noted above.

19

​ Corporate Governance​

Director Independence

The board of directors has determined that each of the following currently serving directors is independent as defined in the listing standards of The NASDAQ Stock Market LLC and our Corporate Governance Guidelines: Charles A. Baker, Michael S. Brown, M.D., Alfred G. Gilman, M.D., Ph.D., Joseph L. Goldstein, M.D., Robert A. Ingram, Christine A. Poon, Arthur F. Ryan, George L. Sing, and Marc Tessier-Lavigne, Ph.D. These individuals are affiliated with numerous educational institutions, hospitals, charities and corporations, as well as civic organizations and professional associations. The board of directors considered each of these relationships and determined that none of these relationships conflicted with the interests of the Company or would impair their independence or judgment. The board conducts executive sessions of independent directors following each regularly scheduled board meeting.

The board of directors has determined that each of the current members of the Audit Committee, Messrs. Baker, Ryan, and Sing, qualifies as an "audit committee financial expert" as that term is defined in Item 407(d)(5)(ii) of Regulation S-K under the Exchange Act, meets the required standards for independence set forth in Rule 10A-3(b)(1) under the Exchange Act, and is independent as defined for audit committee members in the listing standards of The NASDAQ Stock Market LLC.

In addition, the board of directors has determined that each of the current members of the Compensation Committee, Drs. Tessier-Lavigne and Goldstein, Messrs. Baker, Ingram, and Sing, and Ms. Poon, meets the additional independence criteria applicable to compensation committee members under the listing standards of The NASDAQ Stock Market LLC and qualifies as a "Non-Employee Director" pursuant to Rule 16b-3 under the Exchange Act and as an "outside director" within the meaning of Section 162(m) of the Internal Revenue Code.

Board 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.

The board executes its oversight responsibility for risk management directly and through its 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 semi-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.

Board Meetings and Attendance of Directors

The board held five regular meetings and two special meetings in 2014. All directors attended more than 75% of the total number of meetings of the board and committees of the board on which they served. Board members are expected to attend the Company's Annual Meeting of Shareholders absent a pressing reason, although the Company has no formal policy on the matter. All of the directors attended our 2014 Annual Meeting of Shareholders.

Executive Compensation Processes and Procedures; Role of Compensation Consultants

The Compensation Committee is responsible for overseeing the Company's general compensation objectives and programs. We describe the role of the Compensation Committee, as well as the role of our executive officers, in decisions regarding executive compensation (particularly with respect to our

20

Corporate Governance​

Named Officers referred to below under "Executive Compensation") below under "Executive Compensation – Compensation Discussion and Analysis – Section 3 – Executive Compensation Process and Considerations – Overview."

As discussed in greater detail under "Executive Compensation – Compensation Discussion and Analysis – Section 3 – Executive Compensation Process and Considerations," the Compensation Committee has the sole authority to retain its own third-party compensation consultants and in 2014 utilized the services of Frederic W. Cook & Co., Inc. ("Frederic W. Cook"), a compensation consultant. In addition, management retains another compensation consultant for its own use. In 2014, management used the services of Radford, a compensation consultant focused on the technology and life sciences sectors. Radford provided various consulting services to us, including analyzing the competitiveness of specific compensation programs; preparing surveys of competitive pay practices (including the 2014 Radford Global Life Sciences Survey discussed in this proxy statement); and assisting management in the development and analysis of executive compensation recommendations. Reports prepared by Radford that relate to executive compensation may also be shared with the Compensation Committee.

Compensation of Directors

Overview

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 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 the qualifications, expertise, and demands on our directors and benchmarks the Company's practices against similar companies in the biotechnology industry.

Cash Fees and Matching Gift Program

Non-employee directors receive an annual retainer of $55,000 and an annual committee retainer of $10,000 for each standing committee on which the director serves. The Chairman of the Audit Committee receives an additional retainer of $5,000 per year. Non-employee directors are reimbursed for their actual expenses incurred in connection with their activities as directors, which included travel, hotel, and food and entertainment expenses. In addition, directors are

eligible to participate in the Regeneron Matching Gift Program, which was adopted effective January 1, 2013 and is also available to eligible employees. Under this program, the Company matches contributions made to eligible tax-exempt organizations. Effective January 1, 2014, the maximum annual match has been increased to $5,000 (from $2,000) per person.

Annual Stock Option Awards

Pursuant to the terms of the Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan and a resolution of the Compensation Committee adopted on December 16, 2014, each non-employee director receives an automatic grant of a stock option to purchase common stock on the first business day of each year, with an exercise price equal to the fair market value of a share of common stock on the date of grant (determined, for so long as our common stock is listed on the NASDAQ Global Select Market, 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 or, if such date is not a trading day, on the last preceding date on which there was a sale of the Company's common stock on the NASDAQ Global Select Market). These stock options become exercisable as to one-third of the shares on the anniversary of the date of grant in each of the three subsequent calendar years, generally subject to continued service on the board, and generally expire ten years following the date of grant. In 2014, 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 12,750 shares to 10,838 shares of common stock underlying each such stock option. The primary impetus for this decision was to reflect the increase in the Company stock price in the automatic grants and to reduce the potential dilutive impact of these grants. The reduced grants to our non-employee directors were made on January 2, 2015. This decrease constituted the second consecutive double-digit percentage decrease in the annual grant of stock options to our non-employee directors, in each case following high stock appreciation. Stock options granted to a non-employee director in 2013, 2014, and 2015 continue to vest following the retirement of that director provided applicable conditions relating to the length of the director's service and the director's age have been met. If a non-employee director's service as a member of the board is terminated as a result of his or her death, all of the director's stock options will immediately vest in full.

Stock options granted since 2010 to non-employee directors become fully vested automatically upon a change of 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. Previously, stock options

21

​ Corporate Governance​

granted to non-employee directors included a "double-trigger" change of control provision whereby the director's stock options would immediately vest in full in the event that a director's service as a member of the board is terminated without cause within two years of a change of control of the Company.

Compensation Arrangements of the Chairman of the Board of Directors

On December 31, 1998, we entered into an employment agreement with the Chairman of the board of directors, Dr. Vagelos. Dr. Vagelos did not become an officer of the Company or change his title. Pursuant to the terms of his employment agreement, Dr. Vagelos receives an annual salary of $100,000. In the employment agreement, we agreed to recommend to the Compensation Committee that stock option grants be made to Dr. Vagelos for calendar years 2000 through 2003 in the amount of the greater of (a) 125,000 shares or (b) 125% of the highest annual option award granted to an officer of the Company.

In 2011, the Compensation Committee determined that Dr. Vagelos's target grant would be equal to ten times the annual grant for a non-employee member of the board of

directors, setting his target award at 150,000 shares of common stock underlying stock options. In each of 2013 and 2014, the Compensation Committee reduced the award to Dr. Vagelos by 15%, in line with the reduction in the annual stock option awards to our non-employee directors in those years.

​ Executive Officers of the Company​

The following table sets forth, as of April 16, 2015, 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 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 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. 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

1,971,868 shares of Class A stock and 101,305,623 shares of common stock outstanding as of April 16, 2015, 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 16, 2015 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 16, 2015 or are exercisable within sixty days after April 16, 2015 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.
