PROXY STATEMENT

FOR THE 2023 ANNUAL MEETING OF STOCKHOLDERS

JUNE 8, 2023

We have sent you this Proxy Statement and the enclosed Proxy Card because the Board of Directors (the “Board”) of Revolution Medicines, Inc. (referred to herein as the “Company”, “Revolution Medicines”, “we”, “us” or “our”) is soliciting your proxy to vote at our 2023 Annual Meeting of Stockholders (the “Annual Meeting”) to be held on June 8, 2023, at 7:30 a.m. Pacific Time. The Annual Meeting will be held entirely online. You will be able to attend and participate in the Annual Meeting online by registering at www.virtualshareholdermeeting.com/RVMD2023. Once registered you will receive further instructions via email on how to listen to the meeting live, submit questions, and vote.

In addition to solicitations by mail, our directors, officers and employees, without additional remuneration, may solicit proxies by telephone, e-mail and personal interviews. We may retain outside consultants to solicit proxies on our behalf as well. All costs of solicitation of proxies will be borne by us. Brokers, custodians and fiduciaries will be requested to forward proxy soliciting material to the owners of stock held in their names, and we will reimburse them for their reasonable out-of-pocket expenses incurred in connection with the distribution of proxy materials.

Pursuant to the rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to provide access to our Annual Meeting materials, which include this Proxy Statement and our Annual Report on Form 10-K for the year ended December 31, 2022 (the “Form 10-K”), over the Internet in lieu of mailing printed copies. We will begin mailing the Notice of Internet Availability to our stockholders of record as of April 20, 2023 (the “Record Date”) for the first time on or about April 26, 2023. The Notice of Internet Availability will contain instructions on how to access and review the Annual Meeting materials, and will also contain instructions on how to request a printed copy of the Annual Meeting materials. In addition, we have provided brokers, dealers, banks, voting trustees and their nominees, at our expense, with additional copies of our proxy materials and the Form 10-K so that our record holders can supply these materials to the beneficial owners of shares of our common stock as of the Record Date. The Form 10-K is also available on our website at https://ir.revmed.com/sec-filings.

The only outstanding voting securities of Revolution Medicines are shares of common stock, $0.0001 par value per share (the “common stock”), of which there were 106,309,642 shares outstanding as of the Record Date (excluding any treasury shares). The holders of a majority in voting power of the shares of common stock issued and outstanding and entitled to vote, present in person or represented by proxy, are required to hold the Annual Meeting.

INFORMATION ABOUT THE PROXY PROCESS AND VOTING

Why am I receiving these materials?

We have made this Proxy Statement and Proxy Card available to you on the Internet or, upon your request, have delivered printed proxy materials to you, because the Board is soliciting your proxy to vote at the Annual Meeting, including at any adjournments or postponements of the Annual Meeting. You are invited to attend the Annual Meeting online to vote on the proposals described in this Proxy Statement. However, you do not need to attend the Annual Meeting to vote your shares. Instead, you may simply complete, sign and return the Proxy Card, or follow the instructions below to submit your proxy over the telephone or on the Internet.

This Proxy Statement, the Notice of Internet Availability, the Notice of Annual Meeting and accompanying Proxy Card will be first made available for access on or about April 26, 2023 to all stockholders of record entitled to vote at the Annual Meeting.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on the Record Date will be entitled to vote at the Annual Meeting. At the close of business on the Record Date, there were 106,309,642 shares of common stock issued and outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If, at the close of business the Record Date, your shares were registered directly in your name with the transfer agent for our common stock, American Stock Transfer & Trust Company, LLC, then you are a stockholder of record. As a stockholder of record, you may vote at the Annual Meeting by attending the Annual Meeting online and following the instructions posted at www.virtualshareholdermeeting.com/RVMD2023 or you may vote by proxy. Whether or not you plan to attend the Annual Meeting online, we encourage you to fill out and return the Proxy Card or vote by proxy over the telephone or on the Internet as instructed below to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker, Bank or Other Agent

If, on the Record Date, your shares were held in an account at a brokerage firm, bank, dealer, custodian or other similar organization acting as nominee (each, a “Broker”), then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your Broker or other agent on how to vote the shares in your account. You are also invited to register to attend the Annual Meeting online at www.virtualshareholdermeeting.com/RVMD2023. However, since you are not the stockholder of record, you may not vote your shares at the Annual Meeting by attending the Annual Meeting online unless you request and obtain a valid Proxy Card from your Broker or other agent.

What am I being asked to vote on?

You are being asked to vote on three proposals:

2

In addition, you are entitled to vote on any other matters that are properly brought before the Annual Meeting.

How do I vote?

Please note that by casting your vote by proxy, you are authorizing the individuals listed on the Proxy Card to vote your shares in accordance with your instructions and in their discretion with respect to any other matter that may properly come before the Annual Meeting or any adjournments or postponements thereof.

The procedures for voting are as follows:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote at the Annual Meeting online. Alternatively, you may vote by proxy by using the accompanying Proxy Card, over the Internet or by telephone. Whether or not you plan to attend the Annual Meeting online, we encourage you to vote by proxy to ensure your vote is counted. Even if you have submitted a proxy before the Annual Meeting, you may still attend the Annual Meeting online and vote online. In such case, your previously submitted proxy will be disregarded.

Beneficial Owner: Shares Registered in the Name of Broker

If you are a beneficial owner of shares registered in the name of your Broker, you should have received a voting instruction card and voting instructions with these proxy materials from that organization rather than from us. Simply complete and mail the voting instruction card to ensure that your vote is counted. To vote at the Annual Meeting online, you must obtain a valid proxy from your Broker. Follow the instructions from your Broker, bank or other agent included with these proxy materials, or contact your Broker to request a proxy form.

Who counts the votes?

Broadridge Financial Solutions, Inc. (“Broadridge”) has been engaged as our independent agent to tabulate stockholder votes (the “Inspector of Election”). If you are a stockholder of record, your executed Proxy Card is returned directly to Broadridge for tabulation. As noted above, if you hold your shares through a Broker, your Broker returns one Proxy Card to Broadridge on behalf of all its clients.

How are votes counted?

Votes will be counted by the Inspector of Elections appointed for the Annual Meeting. The Inspector of Elections will separately count: for Proposal No. 1, votes “FOR,” “WITHHOLD” and, if applicable, broker non-votes; and with respect to Proposals No. 2 and No. 3, votes “FOR” and “AGAINST,” abstentions and, if applicable, broker non-votes.

If your shares are held by your Broker as your nominee (that is, held beneficially in “street name”), you will need to obtain a proxy form from the institution that holds your shares and follow the instructions included on that form regarding how to instruct your Broker to vote your shares. If you do not give voting instructions to your Broker, your Broker can only vote your shares with respect to “routine” items, but not with respect to “non-routine” items. See below for more information regarding: “What are “broker non-votes”?” and “Which ballot measures are considered “routine” or “non-routine”?”.

What are “broker non-votes”?

Broker non-votes occur when a beneficial owner of shares held in “street name” does not give instructions to the Broker holding the shares as to how to vote on matters deemed “non-routine.” Generally, if shares are held in street name, the beneficial owner of the shares is entitled to give voting instructions to the Broker holding the shares. If the beneficial owner does not provide voting instructions, the Broker can still vote the shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. In the event that a Broker or other record holder of common stock indicates on a proxy that it does not have discretionary authority to vote certain shares on a particular proposal, then those shares will be treated as broker non-votes with respect to that proposal. Accordingly, if you own shares through a nominee, such as a Broker, please be sure to instruct your nominee how to vote to ensure that your vote is counted on each of the proposals.

Which ballot measures are considered “routine” or “non-routine?”

The ratification of the appointment of PricewaterhouseCoopers LLP, as our independent registered public accounting firm for the year ending December 31, 2023 (Proposal No. 2), is considered routine under applicable rules. A Broker may generally vote on routine matters, and therefore no broker non-votes are expected to exist in connection with Proposal No. 2. Proposal No. 1 to elect directors and Proposal No. 3 to approve the Say-on-Pay proposal are each considered non-routine under applicable rules. A Broker cannot vote without instructions on non-routine matters, and therefore there may be broker non-votes on Proposals No. 1 and No. 3.

How many votes are needed to approve each proposal?

Proposal No. 1 — To elect three Class III directors to hold office until our 2026 Annual Meeting of Stockholders and until their respective successors are elected and qualified. Directors shall be elected by a plurality of the votes cast, which means that the three nominees receiving the most “FOR” votes (from the votes of shares present in attendance or represented by proxy and entitled to vote on the election of directors) will be elected. “WITHHOLD” votes and broker non-votes will not be counted towards the vote total for this proposal.

Proposal No. 2 — To ratify the appointment of PricewaterhouseCoopers LLP as the independent registered public accounting firm of the Company for the fiscal year ending December 31, 2023. The ratification of PricewaterhouseCoopers LLP as independent registered public accounting firm for the year ending December 31, 2023 requires the affirmative vote of the majority of the votes cast, which means the number of shares voted “FOR” the proposal must exceed the number of shares voted “AGAINST” such proposal. Abstentions and broker non-votes are not considered votes cast for the foregoing purpose, and will have no effect on the vote for this proposal. Because Proposal No. 2 is considered a “routine” matter, no broker non-votes are expected in connection with this proposal.

Proposal No. 3 — To approve, on a non-binding, advisory basis, the Say-on-Pay proposal. The Say-on-Pay proposal requires the affirmative vote of the majority of the votes cast, which means the number of shares voted

4

“FOR” the proposal must exceed the number of shares voted “AGAINST” such proposal. Abstentions and broker non-votes are not considered votes cast for the foregoing purpose, and will have no effect on the vote for this proposal.

Because votes on Proposal No. 3 are advisory, they will not be binding on the Board, the Compensation Committee of the Board or the Company. With respect to Proposal No. 3, the Board will review the voting results and take them into consideration when making future decisions about executive compensation.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you own as of the Record Date.

What if I return a Proxy Card but do not make specific choices?

If we receive a signed and dated Proxy Card and the Proxy Card does not specify how your shares are to be voted, your shares will be voted as follows:

If any other matter is properly presented at the Annual Meeting, your proxy (one of the individuals named on your Proxy Card) will vote your shares in his or her discretion.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies. In addition to these mailed proxy materials, our directors, officers and employees may also solicit proxies in person, by telephone or by other means of communication. Directors, officers and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

What does it mean if I receive more than one set of materials?

If you receive more than one set of materials, your shares are registered in more than one name or are registered in different accounts. In order to vote all the shares you own, you must either sign and return all of the Proxy Cards or follow the instructions for any alternative voting procedure on each of the Proxy Cards.

Can I change my vote after submitting my proxy?

Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting. If you are the record holder of your shares, you may revoke your proxy in any one of three ways:

If your shares are held by your Broker, you should follow the instructions provided by them.

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by December 28, 2023 to the Secretary of the Company at 700 Saginaw Drive, Redwood City, California 94063; provided, that if the date of the annual meeting is more than 30 days from June 8, 2024, the deadline is a reasonable time before we begin to print and send our proxy materials for next year’s annual meeting. Pursuant to our bylaws, in order for a stockholder to present a proposal for next year’s annual meeting, other than proposals to be included in the proxy statement as described above, or to nominate a director, you must do so between February 9, 2024 and March 10, 2024; provided, that if the date of that annual meeting is more than 30 days before or more than 60 days after June 8, 2024, you must give notice not later than the 90th day prior to the annual meeting date or, if later, the 10th day following the day on which public disclosure of the annual meeting date is first made. You are also advised to review our bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations. In addition to satisfying the foregoing requirements under our bylaws, stockholders who intend to solicit proxies in support of director nominees other than our nominees in connection with next year’s annual meeting of stockholders must provide notice that sets forth the information required by Rule 14a-19 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), no later than April 9, 2024. If the date of the 2024 Annual Meeting of Stockholders is changed by more than 30 days from the anniversary of the 2023 Annual Meeting of Stockholders, then notice must be provided by the later of 60 days prior to the date of the 2024 annual meeting of stockholders or the 10th calendar day following the day on which public announcement of the date of the 2024 Annual Meeting of Stockholders is first made.

PROPOSAL NO. 1

ELECTION OF DIRECTORS

Our Board is divided into three classes. Each class consists, as nearly as possible, of one-third of the total number of directors, and each class has a staggered, three-year term. Unless the Board determines that vacancies (including vacancies created by increases in the number of directors) shall be filled by the stockholders, and except as otherwise provided by law, vacancies on the Board may be filled only by the affirmative vote of a majority of the remaining directors. A director elected by the Board to fill a vacancy (including a vacancy created by an increase in the number of directors) shall serve for the remainder of the full term of the class of directors in which the vacancy occurred and until such director’s successor is elected and qualified.

The Board currently consists of nine seated directors, divided into the three following classes:

At each annual meeting of stockholders, the successors to directors whose terms will then expire will be elected to serve from the time of election and qualification until the third subsequent annual meeting of stockholders.

Alexis Borisy, Mark A. Goldsmith, M.D., Ph.D. and Barbara Weber, M.D. have each been nominated to serve as Class III directors and have agreed to stand for election. If elected, each of Mr. Borisy, Dr. Goldsmith and Dr. Weber will hold office from the date of their election by the stockholders until the third subsequent annual meeting of stockholders or until their respective successor is elected and has been qualified, or until such director’s earlier death, resignation or removal.

Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the three nominees named above. In the event that any nominee should be unavailable for election as a result of an unexpected occurrence, such shares will be voted for the election of such substitute nominee as the Board may propose. Mr. Borisy, Dr. Goldsmith and Dr. Weber have agreed to serve if elected, and management has no reason to believe that they will be unable to serve. Directors are elected by a plurality of the votes cast at the meeting.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE

FOR THE ELECTION OF EACH NAMED NOMINEE.

The following table sets forth, for the Class III nominees who are currently standing for election and for our other current directors who will continue in office after the Annual Meeting, information with respect to their ages as of March 31, 2023 and position/office held with the Company:

Set forth below is biographical information for each of the nominees and each person whose term of office as a director will continue after the Annual Meeting. The following includes certain information regarding our directors’ individual experience, qualifications, attributes and skills that led the Board to conclude that they should serve as directors.

9

multiple biopharmaceutical and life sciences companies, his educational background and his experience working in the venture capital industry provide him with the qualifications and skills necessary to serve as a member of our Board of Directors. Mr. Borisy attended all of our Board and relevant committee meetings in 2022 and we believe that Mr. Borisy will continue to successfully perform his duties as a director of Revolution Medicines while serving as a member of the boards of directors of other public companies.

Mark A. Goldsmith, M.D., Ph.D. has served on our Board of Directors and as our Chief Executive Officer and President since November 2014.

Dr. Goldsmith received an A.B. in Biology from Princeton University and an M.D. and Ph.D. in Microbiology and Immunology from the School of Medicine of the University of California, San Francisco. We believe that Dr. Goldsmith’s role as our Chair of the Board, Chief Executive Officer and President together with his extensive experience as an executive and director of several companies in the biopharmaceutical and biotechnology industry, his extensive knowledge of our company, his experience as a venture capital investor in the life sciences industry and his educational background provide him with the qualifications and skills necessary to serve as a member of our Board of Directors.

PROPOSAL NO. 2

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of our Board has appointed PricewaterhouseCoopers LLP (“PwC”) as our independent registered public accounting firm for the year ending December 31, 2023, and is seeking ratification of this selection by our stockholders at the Annual Meeting. PwC has audited our financial statements for each of our fiscal years since the fiscal year ended December 31, 2017. Representatives of PwC are expected to be in attendance online at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our bylaws nor other governing documents or law require stockholder ratification of the selection of PwC as our independent registered public accounting firm. However, the Audit Committee is submitting the selection of PwC to our stockholders for ratification as a matter of good corporate practice. If our stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain PwC. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of the Company and our stockholders.

Principal Accountant Fees and Services

The following table represents aggregate fees billed to us for services provided by PwC relating to the fiscal years ended December 31, 2022 and 2021.

Pre-Approval Policies and Procedures

Pursuant to its charter, the Audit Committee or a delegate of the Audit Committee pre-approves all audit and non-audit services provided by its independent registered public accounting firm, unless the engagement is entered into pursuant to appropriate additional pre-approval policies established by the Audit Committee or if such service falls within applicable exceptions under SEC rules. The Audit Committee pre-approved all services provided by PwC for the fiscal years ended December 31, 2022 and 2021.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE

FOR RATIFICATION OF OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM.

PROPOSAL NO. 3

APPROVAL, ON A NON-BINDING, ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS (“SAY-ON-PAY VOTE”)

As required by Section 14A(a)(1) of the Exchange Act and related rules of the SEC, the below resolution provides our stockholders an opportunity to vote to approve, on a non-binding, advisory basis, the compensation of our named executive officers as disclosed in this Proxy Statement pursuant to the SEC’s compensation disclosure rules. This proposal, commonly known as a “say-on-pay” proposal and vote, is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies, and practices described in this Proxy Statement.

We encourage our stockholders to review the “Compensation Discussion and Analysis” and “Executive Compensation Tables” sections of this Proxy Statement for additional detail regarding the compensation of our named executive officers.

As an advisory approval, this proposal is not binding upon us, our Board, or our Compensation Committee, which are responsible for the design and administration of our executive compensation program. However, we, the Board and the Compensation Committee value the opinions of our stockholders expressed through your vote on this proposal and will carefully consider stockholder feedback and the results of Say-on-Pay Votes when making future compensation decisions. Accordingly, we ask our stockholders to vote on the following resolution at the Annual Meeting:

“RESOLVED, that the stockholders of Revolution Medicines, Inc. approve, on an advisory basis, the 2022 compensation of Revolution Medicines, Inc.’s named executive officers as described in the Compensation Discussion and Analysis and disclosed in the Summary Compensation Table and related compensation tables and narrative disclosure set forth in Revolution Medicines, Inc.’s Proxy Statement for the 2023 Annual Meeting of Stockholders.”

Unless the Board of Directors decides to modify its policy regarding the frequency of soliciting Say-on-Pay Votes, the next scheduled Say-on-Pay Vote will be at the 2024 Annual Meeting of Stockholders.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE

FOR THE FOREGOING RESOLUTION.

CORPORATE GOVERNANCE

Code of Business Conduct and Ethics

We have adopted a Code of Business Conduct and Ethics that applies to our officers, directors and employees, which is available on our website at https://ir.revmed.com/governance-overview. The Code of Business Conduct and Ethics contains general guidelines for conducting the business of our company consistent with the highest standards of business ethics and is intended to qualify as a “code of ethics” within the meaning of Section 406 of the Sarbanes-Oxley Act of 2002 and Item 406 of Regulation S-K. In addition, we intend to promptly disclose (1) the nature of any substantive amendment to 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 and the date of such amendment and (2) the nature of any waiver, including an implicit waiver, from a provision of our code of ethics that is granted to one of these specified officers, the name of such person who is granted the waiver and the date of the waiver, in each case, on our website in the future.

Corporate Governance Guidelines

We believe in sound corporate governance practices and have adopted formal Corporate Governance Guidelines to enhance our effectiveness. Our Board adopted these Corporate Governance Guidelines in order to ensure that it has the necessary practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The Corporate Governance Guidelines are also intended to align the interests of directors with those of our stockholders. The Corporate Governance Guidelines set forth the practices our Board follows with respect to Board and committee composition and selection, Board meetings, and succession planning. The Corporate Governance Guidelines include the Board’s standards used in nominating director candidates, which include candidates who have a high level of personal and professional integrity, strong ethics and values and the ability to make mature business judgments. The Corporate Governance Guidelines memorialize the Board’s belief that a diversity of viewpoints, background, experience and other characteristics, such as geographic background, nationality, culture, gender, sexual orientation, ethnicity, race and age, that a candidate would bring (including in light of applicable diversity requirements regarding gender, underrepresented communities or otherwise) are important additional criteria that may be considered. A copy of our Corporate Governance Guidelines is available on our website at http://ir.revmed.com/governance-overview.

Independence of the Board of Directors

As required under the Nasdaq Global Select Market (“Nasdaq”) rules and regulations, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by such board. The Board consults with the Company’s counsel to ensure that the Board’s determinations are consistent with all relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent Nasdaq listing standards, as in effect from time to time.

Consistent with these considerations, our Board has determined that all of our directors, other than Dr. Goldsmith, qualify as “independent” directors in accordance with the Nasdaq listing requirements. Dr. Goldsmith is not considered independent because he is an employee of Revolution Medicines. The Nasdaq independence definition includes a series of objective tests, such as that the director is not, and has not been for at least three years, one of our employees and that neither the director nor any of his or her family members has engaged in various types of business dealings with us. In addition, as required by Nasdaq rules, our Board has made a subjective determination as to each independent director that no relationship exists, which, in the opinion of our Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations, our Board reviewed and discussed information provided by the directors and us with regard to each director’s business and personal activities and relationships as they may relate to us and our management. There are no family relationships among any of our directors or executive officers.

16

As required under Nasdaq rules and regulations, our independent directors meet in regularly scheduled executive sessions at which only independent directors are present. Each of the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee of our Board are comprised entirely of directors determined by the Board to be independent within the meaning of Nasdaq and SEC rules and regulations applicable to the members of such committees.

Leadership Structure of the Board

Our bylaws, as amended and restated to date, and Corporate Governance Guidelines provide our Board with flexibility to combine or separate the positions of Chair of the Board and Chief Executive Officer and/or to implement a lead director in accordance with its determination that utilizing one or the other structure would be in the best interests of the Company. Dr. Goldsmith currently serves as the Chair of the Board and Mr. Borisy currently serves as the lead independent director of our Board. In his role as lead independent director, Mr. Borisy presides over the executive sessions of the Board and acts as a liaison between management and the Board.

Our Board has concluded that our current leadership structure is appropriate at this time. However, our Board will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate.

Role of Board in Risk Oversight Process

Risk assessment and oversight are an integral part of our governance and management processes. Our Board encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management meetings, and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us. Throughout the year, senior management reviews these risks with the Board at regular Board meetings as part of management presentations that focus on particular business functions, operations or strategies and presents the steps taken by management to mitigate or eliminate such risks.

Our Board does not have a standing risk management committee, but rather administers this oversight function directly through our Board as a whole, as well as through various standing committees of our Board that address risks inherent in their respective areas of oversight. While our Board is responsible for monitoring and assessing strategic risk exposure, our Audit Committee is responsible for periodically reviewing and discussing with management our policies with respect to risk assessment and risk management and for overseeing our major financial risk exposures and the steps our management has taken to monitor and control these exposures. The Audit Committee also monitors compliance with legal and regulatory requirements and considers and approves or disapproves any related person transactions. Our Nominating and Corporate Governance Committee provides oversight with respect to environmental, social and governance matters, including monitoring the effectiveness of our corporate governance guidelines. Our Compensation Committee has responsibility for compensation risk related to our compensation plans, including assessing and monitoring whether any of our compensation policies and programs has the potential to encourage excessive risk-taking.

Board Committees

Our Board has the following standing committees: an Audit Committee, a Compensation Committee, a Nominating and Corporate Governance Committee and a Research and Development Committee. Our Board may establish other committees to facilitate the management of our business. The composition and functions of each committee are described below.

17

Audit Committee

Our Audit Committee oversees our corporate accounting and financial reporting process and the audits of our financial statements. Among other matters, the Audit Committee:

The current members of our Audit Committee are Eric T. Schmidt, Ph.D., Lorence Kim, M.D. and Thilo Schroeder, Ph.D. Dr. Schmidt serves as the chair of the committee. All members of our Audit Committee meet the requirements for financial literacy under the applicable rules and regulations of the SEC and Nasdaq. Our Board has determined that Dr. Schmidt and Dr. Kim are audit committee financial experts as defined under the applicable rules of the SEC and have the requisite financial sophistication as defined under the applicable rules and regulations of Nasdaq. Under the rules of the SEC, members of the audit committee must also meet heightened independence standards. Our Board has determined that Dr. Schmidt, Dr. Kim and Dr. Schroeder are “independent” for audit committee purposes as that term is defined in the applicable rules of the SEC and Nasdaq.

The Audit Committee operates under a written charter that satisfies the applicable standards of the SEC and Nasdaq. A copy of the Audit Committee charter is available to security holders on the Company’s website at http://ir.revmed.com/governance-overview.

Compensation Committee

Our Compensation Committee oversees policies relating to compensation and benefits of our directors, officers and employees and compliance with applicable compensation rules. Among other things, the Compensation Committee:

18

The current members of our Compensation Committee are Elizabeth McKee Anderson, Alexis Borisy and Flavia Borellini, Ph.D. Ms. Anderson serves as the chair of the Compensation Committee. Each of the members of our Compensation Committee is independent under the applicable rules and regulations of Nasdaq, and is a “non-employee director” as defined in Rule 16b-3 promulgated under the Exchange Act.

The Compensation Committee operates under a written charter that satisfies the applicable standards of the SEC and Nasdaq rules. The Compensation Committee’s charter permits it to delegate its authority and responsibilities to a subcommittee of Compensation Committee members, subject to certain limitations and guidelines. A copy of the Compensation Committee charter is available to security holders on the Company’s website at http://ir.revmed.com/governance-overview.

The Compensation Committee has retained Compensia, a national executive compensation consulting firm as independent compensation consultant to the Compensation Committee. Compensia was engaged to conduct market research and analysis on our various executive positions, to assist the committee in developing appropriate incentive plans for our executives on an annual basis, to provide the Compensation Committee with advice and ongoing recommendations regarding material executive compensation decisions, and to review compensation proposals proposed by management. In compliance with the disclosure requirements of the SEC regarding the independence of compensation consultants, Compensia addressed each of the six independence factors established by the SEC with the Compensation Committee. Each of the responses affirmed the independence of Compensia on executive compensation matters. Based on this assessment, the Compensation Committee determined that the engagement of Compensia does not raise any conflicts of interest or similar concerns.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee is responsible for making recommendations to our Board regarding candidates for directorships and the size and composition of our Board. In addition, the Nominating and Corporate Governance Committee is responsible for overseeing our corporate governance policies and reporting and making recommendations to our Board concerning governance matters and for overseeing the annual self-evaluation of the Board and its committees. The Nominating and Corporate Governance Committee also reviews, assesses and provides oversight with respect to corporate social responsibility, including but not limited to, diversity and inclusion goals, and other matters related to corporate social responsibility, environmental, social and governance matters.

19

The current members of our Nominating and Corporate Governance Committee are Lorence Kim, M.D., Alexis Borisy and Barbara Weber, M.D. Dr. Kim serves as the chair of the Nominating and Corporate Governance Committee. Each of the members of our Nominating and Corporate Governance Committee is an independent director under the applicable rules and regulations of Nasdaq relating to Nominating and Corporate Governance Committee independence.

The Nominating and Corporate Governance Committee operates under a written charter that satisfies the applicable standards of the SEC and Nasdaq rules. A copy of the Nominating and Corporate Governance Committee charter is available to security holders on the Company’s website at http://ir.revmed.com/governance-overview.

Our Nominating and Corporate Governance Committee is responsible for identifying individuals qualified to become members of the Board and ensuring that the Board has the requisite expertise and that its membership consists of persons with sufficiently diverse and independent backgrounds. The Nominating and Corporate Governance Committee also recommends to the Board the nominees for election at our annual meetings of stockholders. The Nominating and Corporate Governance Committee, in recommending candidates for election to the Board, and the Board in nominating director candidates, consider candidates who have a high level of personal and professional integrity, strong ethics and values and the ability to make mature business judgments. In evaluating director candidates, the Nominating and Corporate Governance Committee and the Board may also consider the following criteria, as well as any other factor they deem relevant:

Currently, our Nominating and Corporate Governance Committee and Board evaluate each individual in the context of the Board as a whole, with the objective of assembling a group that can best maximize the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of experience in these various areas.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. For a stockholder to make any nomination for election to the Board at an annual meeting, the stockholder must provide notice to the Company, which notice must be delivered to, or mailed and received at, the Company’s principal executive offices not less than 90 days and not more than 120 days prior to the one-year anniversary of the preceding year’s annual meeting; provided, that if the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, the stockholder’s notice must be delivered, or mailed and received, not later than 90 days prior to the date of the annual meeting or, if later, 10 days after the date on which public disclosure of the date of such annual meeting was first made. Further updates and supplements to such notice may be required at the times, and in the forms, required under our bylaws. As set forth in our bylaws, submissions must include the name and address of the proposed nominee, indirect and direct interests in securities of the Company, information regarding the proposed nominee that is required to be

Our bylaws also specify further requirements as to the form and content of a stockholder’s notice. We recommend that any stockholder wishing to make a nomination for director review a copy of our bylaws, as amended and restated to date, which are available, without charge, from the Secretary of the Company, at 700 Saginaw Drive, Redwood City, California 94063.

22

DIRECTOR COMPENSATION

We do not provide directors who are also our employees, including Dr. Goldsmith, any additional compensation for their service as directors. In addition, Dr. Schroeder does not receive any compensation for his service on our Board of Directors.

In connection with our initial public offering, we adopted and implemented a compensation program for our non-employee directors, which was most recently amended in March 2023 (the “Director Compensation Program”). Pursuant to the Director Compensation Program, our non-employee directors receive cash compensation as follows:

Under the Director Compensation Program, each non-employee director is automatically granted an option and a restricted stock unit (“RSU”) grant upon the director’s initial appointment or election to our Board of Directors (the “Initial Grant”), and each non-employee director who has been serving on our Board of Directors prior to April 1 of the calendar year in which an annual meeting of stockholders occurs is automatically granted an option and an RSU grant on the date of each annual stockholders’ meeting (the “Annual Grant”); provided that the Annual Grant to a director who joined the Board after the previous annual meeting of stockholders is pro-rated.

The Initial Grant is comprised of an option to purchase 36,800 shares of the Company’s common stock (the “Initial Option”) and 10,500 restricted stock units (the “Initial RSUs”). The Initial Option will vest in substantially equal monthly installments for three years from the date of appointment, and the Initial RSUs will vest in substantially equal quarterly installments over a three-year period beginning on the first specified

23

quarterly vesting date following the grant date, in each case, subject to continued service through the applicable vesting date.

Under the amended Director Compensation Program, the Annual Grant is comprised of an option to purchase 18,400 shares of the Company’s common stock (the “Annual Option”) and 5,200 restricted stock units (the “Annual RSUs”), provided that, commencing in 2023, the cumulative fair value of the Annual Option and Annual RSUs (valued based on the average closing price of the Company’s common stock for the 30 trading days preceding the grant date) shall be capped at $550,000. The Annual Options vest on the earlier of (i) the first anniversary of the date of grant or (ii) immediately prior to the next annual stockholders’ meeting, subject to continued service through the applicable vesting date. The Annual RSUs vest on the earlier of (i) the first anniversary of the first specified quarterly vesting date following the annual meeting or (ii) immediately prior to the next annual stockholders’ meeting, subject to continued service through the applicable vesting date. For purposes of the amended Director Compensation Program, the specified quarterly vesting dates are March 15, June 15, September 15 or December 15.

The Director Compensation Program is subject to all the terms of our 2020 Incentive Award Plan, and accordingly, the sum of the grant date fair value of all equity-based awards and the maximum amount that may become payable pursuant to all cash-based awards granted to an individual for services as a non-employee director during any calendar year may not exceed $1,000,000.

COMPENSATION DISCUSSION AND ANALYSIS

In this Compensation Discussion and Analysis (“CD&A”), we provide an overview of the philosophy and objectives of our executive compensation program, as well as a description of its material components. This CD&A is intended to be read in conjunction with the tables that immediately follow this section, which provide further historical compensation information for our named executive officers (our “NEOs”).

Our NEOs for the year ended December 31, 2022 were:

Executive Summary

Revolution Medicines is a clinical-stage precision oncology company focused on developing targeted therapies to inhibit frontier targets in RAS-addicted cancers. We possess sophisticated structure-based drug discovery capabilities built upon deep chemical biology and cancer pharmacology know-how and innovative, proprietary technologies that enable the creation of small molecules tailored to unconventional binding sites. Our understanding of genetic drivers and adaptive resistance mechanisms in cancer, coupled with robust drug discovery and medicinal chemistry capabilities, has guided us to establish a deep pipeline targeting critical signaling nodes within the RAS pathway and associated pathways.

In 2022, we continued to make clinical and operational progress, advancing two of our innovative RAS(ON) Inhibitors into clinical trials and expanding our clinical evaluation of the RAS Companion Inhibitors in our pipeline. We maintained a strong financial position despite a challenging financial environment and ended 2022 with cash, cash equivalents and marketable securities of $644.9 million.

Compensation Philosophy and Objectives

We believe that a well-designed compensation program should align executive interests with those of stockholders by supporting the Company’s achievement of its primary business goals, and the Company’s ability to attract and retain employees whose leadership and contributions are expected to lead to growth in long-term stockholder value.

As such, our executive compensation program is designed to:

Our Compensation Committee regularly reviews our compensation policies and program design overall, to ensure that they are aligned with the interests of our stockholders and our business goals, and that the total compensation paid to our executive officers is fair, reasonable and competitive.

29

Compensation Elements

Our Compensation Committee has structured our executive compensation program to compensate our NEOs in a manner consistent with our pay philosophy and objectives as well as with stockholder interests. The following are important features of the design and operation of our executive compensation program:

Pay Mix Overview

We use the above-mentioned compensation elements to create executive compensation packages that are heavily weighted toward variable, “at-risk” pay and align pay with performance. For 2022, our Compensation Committee used its judgment, as well as competitive market data in consultation with its independent compensation consultant, to establish for our CEO and our other NEOs the following mix of fixed and “at-risk” pay, as well as short-term and long-term incentive compensation, and cash and equity compensation. The balance between these elements may change from year to year based on our corporate strategy and objectives, among other considerations.

30

Key Governance Features

We adhere to the following principles that encourage stockholder value creation and good governance:

Compensation Determination Process

Role of Compensation Committee

Our Compensation Committee has responsibility for our executive compensation philosophy and the design of our executive compensation program, as well as for setting actual executive compensation for our CEO and our other NEOs. Our Compensation Committee conducts an annual review of the Company’s compensation policies and practices, with a goal of aligning executive incentives and performance with those of our stockholders. Our Compensation Committee reviews NEO base salaries, annual cash incentive opportunities, and long-term equity incentives to determine the total direct compensation opportunities of our NEOs.

Role of Management

To assist the Compensation Committee in its responsibilities, our CEO presents to the Compensation Committee assessments of the performance and achievements for each of our NEOs (other than himself) for the prior year. Our Compensation Committee gives considerable weight to our CEO’s performance evaluations of our other NEOs, since he has direct knowledge of the importance of their work to achieving our corporate objectives and their performance and contributions. None of our NEOs, including our CEO, participate in the Compensation Committee’s deliberations or decisions regarding their own compensation and are not present when their compensation is determined.

Role of our Stockholders

At our 2022 annual meeting of stockholders, our stockholders voted, in a non-binding advisory vote (a “Say-on-Pay” vote, to approve the compensation of our NEOs (with an approval representing approximately 92%

31

of the shares represented in person or by proxy at the meeting and entitled to vote). Our Compensation Committee reviewed the result of the stockholders’ advisory vote on executive compensation and, in light of the approval by a substantial majority of stockholders, did not implement changes to the executive compensation programs solely as a result of the vote.

At this annual meeting of stockholders, we are again holding an advisory Say-on-Pay vote. We, our board of directors and our Compensation Committee value the opinions of our stockholders expressed through the Say-on-Pay vote and will carefully consider stockholder feedback and the results of this vote when making compensation decisions.

Role of our Compensation Consultant

In 2022, our Compensation Committee retained Compensia as its compensation consultant to assist in determining the compensation of our executive officers and the non-employee members of our board of directors, as well as to assist in the review of certain proxy statement disclosures. Compensia reviewed and advised on the Company’s executive compensation and compensation peer group, and conducted a robust assessment of competitive market pay levels and trends.

Our Compensation Committee annually evaluates Compensia’s independence and performance under the applicable SEC rules and the listing standards of Nasdaq, and has concluded that the work performed by Compensia does not raise any conflict of interest under these standards.

Use of Market Data and Peer Group Analysis

When reviewing and considering our executive compensation, our Compensation Committee believes it is important to be informed as to current compensation practices of comparable companies to assist in understanding the demand and competitiveness for attracting and retaining qualified executive officers. Our Compensation Committee, with input from Compensia, develops and maintains a group of peer companies to serve the basis for this comparison. Our Compensation Committee reviews our compensation peer group at least annually for suitability and updates the peer group as needed. Our Compensation Committee uses this peer group data as one reference point along with multiple other factors, such as the importance of an individual’s work to achieving our corporate objectives, an individual’s experience and performance and data from surveys of the broader competitive market, with an emphasis on companies in Northern California and the broader life sciences industry.

With assistance from Compensia, our Compensation Committee reviews the compensation practices of our peers to assess the competitiveness of the compensation elements and overall compensation packages for our NEOs. Benchmarking is used by our Compensation Committee primarily to ascertain competitive total compensation levels (including base salary, annual cash incentive opportunities, equity awards, and employee benefits) with comparable entities. Other considerations include peer performance, competitive market factors, our performance and individual executive officer contributions and responsibilities.

The key qualitative and quantitative considerations that influenced the development of the 2022 compensation peer group were:

32

Using these criteria, our Compensation Committee approved the following compensation peer group in August 2021 for use in making its 2022 compensation decisions:

Compared to the peer group used for 2021 compensation decisions, Constellation Pharmaceuticals and Principia Biopharma were removed because of corporate transactions involving these companies and Fate Therapeutics, Gossamer Bio, Molecular Templates, NextCure and Odonate Therapeutics were removed because of our market capitalization guidelines. C4 Therapeutics, Kura Oncology, Nurix Therapeutics, Relay Therapeutics, Replimune, Rubius Therapeutics, SpringWorks Therapeutics and Zentalis Pharmaceuticals were added to our peer group because they met the criteria set forth above.

Elements of Executive Compensation

Base Salary

Base salary is the only fixed element of our NEOs’ total cash compensation. Our base salaries are determined using market-based assessments (in accordance with the description in the “Use of Market Data and Peer Group Analysis” section above) while also considering individual responsibilities, skills, knowledge, expertise and performance. As part of our annual compensation review, salaries for our NEOs are determined in the first quarter of each fiscal year and are effective as of March 1. The 2022 and 2021 annual base salaries of our NEOs after these adjustments were as follows:

In addition to our annual compensation review, our Compensation Committee will re-evaluate salaries in connection with promotions. In September 2022, in connection with Mr. Anders’s promotion to Chief Financial Officer, our Compensation Committee increased his annual base salary to $430,000.

Annual Cash Incentives

Our annual cash incentives are based on the achievement of key corporate and individual goals. Our NEOs are eligible to earn annual cash bonuses based on the achievement of certain corporate performance objectives approved by our Compensation Committee and our board of directors as well as, in the case of our NEOs other than our CEO, their individual performance objectives. The full bonus for our CEO is determined based on our corporate score, and for our other NEOs corporate achievement is weighted 90% and individual achievement is weighted 10%. Each NEO’s target annual cash incentive opportunity is expressed as a percentage of base salary and intended to be commensurate with the NEO’s position and responsibilities. In connection with our annual compensation review, in the first quarter of 2022, after considering market data and our continued maturation as

33

a public company, our Compensation Committee approved increasing the target annual cash incentive opportunity for our CEO by 5% of base salary for 2022, and confirmed the target annual cash incentive opportunities for our other NEOs as set forth in the table below.

In September 2022, in connection with Mr. Anders’s promotion to Chief Financial Officer, our Compensation Committee increased his target cash incentive opportunity to 40% of his base salary effective as of September 1, 2022.

2022 Corporate Performance Goals

The annual cash incentives for our NEOs are based on the achievement of corporate performance objectives and, other than in the case of our CEO, an assessment of individual performance. For 2022, the corporate performance goals included the following components:

34

2022 Earned Incentive Awards

Our Compensation Committee and our board of directors assessed the level of achievement of the 2022 corporate goals in January 2023. Based on its assessment of our achievements related to these goals as described above, including overachievement in our pipeline advancement activities, financial goals and hiring and retention, and the assessment and recommendation of our Compensation Committee, our board of directors determined that we achieved 120% of our corporate performance goals.

Our Compensation Committee assessed the individual performance for each of our NEOs in February 2023. The full annual cash incentive for our CEO was determined based on our corporate score, and for our other NEOs corporate achievement was weighted 90% and individual achievement was weighted 10%. The Compensation Committee considered each of the other NEOs individual contributions to our strong corporate performance overall, as well as specifically for Mr. Anders, his overall responsibility and contributions to meeting the company’s financial objectives, for Dr. Kelsey, his overall responsibility and contributions to the outperformance and achievements in meeting research and development objectives, for Ms. Horn, her oversight of complex strategic matters and overall responsibility and contributions to executing our corporate development priorities, and for Ms. Wang, her responsibility and contributions to meeting development goals and achieving key clinical milestones. As such our Compensation Committee paid our NEOs the percentages of their target annual cash incentive opportunities set forth below.

Long-Term Equity Incentives

We believe that equity awards are a crucial component of our executive compensation program to motivate our NEOs to focus on sustained long-term growth and link to stockholder value creation. Additionally, equity

35

awards provide an important retention element in our executive compensation program, since they vest over four years. In addition, our NEOs will only realize value from their stock options if the market price of our common stock increases after the date the option is granted.

For 2022, in consultation with Compensia, our Compensation Committee approved equity awards after taking into consideration its assessment of peer group awards, a competitive market analysis performed by Compensia, our CEO’s recommendations (except with respect to his own award) and our Compensation Committee’s evaluation of each NEO’s individual responsibilities, performance, contributions and our retention objectives, as well as the number of shares of common stock in our equity pool, each NEO’s current individual equity holdings and each NEO’s overall total direct compensation. After taking into consideration market practices among our peer group and our retention objectives, our Compensation Committee utilized a mix of 70% stock options and 30% RSU awards, based on the grant date fair value of these awards.

All of the RSU awards and stock options granted vest over a four-year period subject to the NEO’s continued service with us on each applicable vesting date. Annual stock option awards vest in equal monthly installments over that four-year period and annual RSU awards vest in equal quarterly installments over that four-year period. The following equity awards were granted to our NEOs in March 2022:

In September 2022, in connection with Mr. Anders’s promotion to Chief Financial Officer, and based on its review of market data, Mr. Anders’s existing equity awards and his individual performance, our Compensation Committee granted Mr. Anders an option to purchase 35,000 shares of our common stock and 10,000 RSUs. The stock option vests in substantially equal monthly installments and the RSUs vest in substantially equal quarterly installments, in each case, over four years and subject to continued service through the applicable vesting date.

Other Elements of Executive Compensation

Prohibition on Hedging, Pledging and Similar Transactions

All employees, officers, the non-employee members of our board of directors and certain consultants of the Company are subject to our Insider Trading Compliance Policy. The policy prohibits the covered individuals from purchasing or selling any of our securities while in possession of material nonpublic information.

Our Insider Trading Compliance Policy also prohibits covered individuals, including our NEOs, from (i) making short sales of our securities, (ii) engaging in transactions in puts, calls or other options or derivative instruments related to our securities, (iii) engaging in any hedging or similar transaction designed to decrease the risks associated with holding our securities and (iv) purchasing our securities on margin or pledging our securities as collateral.

Health and Welfare Benefits and Perquisites

We offer employee benefit programs that are intended to provide financial protection and security for our employees and to reward them for the commitment we expect from them while employed by us. These benefit plans include medical, dental, group life and disability insurance plans. In addition, for our retirement program, we offer a Section 401(k) retirement savings plan which is a defined contribution plan established in accordance with Section 401 of the Internal Revenue Code that provides our employees with the opportunity to defer their

36

eligible compensation on a pre-tax basis, up to statutorily prescribed annual limits and to have this amount contributed to the Section 401(k) plan. In 2022, we provided a matching contribution equal to 50% of the participant’s elective contributions up to $7,000 of eligible compensation. All of our NEOs are eligible to participate in these programs on the same basis as our other employees. We do not provide perquisites or other personal benefits to our NEOs.

Severance and Change in Control Payments and Benefits

We have entered into employment agreements with each of our NEOs. Through these agreements, our NEOs are provided with certain severance payments and benefits in the event of certain involuntary terminations of employment in order to assist us in recruiting and retaining talented individuals and align the NEOs’ interests with the best interests of stockholders. We believe these severance payments and benefits are consistent with those provided in the life sciences industry and are an essential element of our overall executive compensation program due to the competitive market for executive talent in our industry.

Enhanced severance payments and benefits are provided for a qualifying termination of employment that occurs in connection with a change in control of the Company because the severance payments and benefits are also intended to eliminate, or at least reduce, the reluctance of our NEOs to diligently consider and pursue potential change-in-control transactions that may be in the best interests of our stockholders. These arrangements are considered “double-trigger”, as they require both a change in control of the Company as well as a qualifying termination of employment. We do not provide any tax reimbursements or tax gross-up payments on severance benefits. A summary of executive severance agreements as well as estimated payments and benefits resulting from a qualified termination or change in control are described below under the heading “Potential Payments upon Termination or Change in Control”.

Tax and Accounting Implications

One of the factors our Compensation Committee considers when determining executive compensation is the anticipated tax treatment to our Company and to our executive officers of the various payments and benefits. Section 162(m) of the Internal Revenue Code (“Section 162(m)”) generally provides that a publicly held company may not deduct compensation paid to certain covered executive officers to the extent that such compensation exceeds $1,000,000 per executive officer in any year. Our Compensation Committee has concluded, and reserves the discretion to conclude in the future, that it is appropriate to exceed the limitation on deductibility under Section 162(m) to ensure that executive officers are compensated in a manner that it believes to be consistent with our Company’s best interests and those of our stockholders.

Under the Financial Accounting Standard Board (“FASB”) Accounting Standards Codification (Topic 718) (“ASC 718”), we are required to estimate and record an expense for each award of equity compensation (including stock options and RSUs) over the vesting period of the award. We record share-based compensation expense on an ongoing basis according to ASC 718. Our Compensation Committee has considered, and may in the future consider, the grant of performance-based or other types of stock awards to executive officers in lieu of or in addition to stock option and time-based RSU grants in light of the accounting impact of ASC 718 and other considerations.

Potential Payments Upon Termination or Change in Control

We have entered into employment agreements with our named executive officers. Pursuant to the terms of these employment agreements, in the event the named executive officer is terminated without Cause or resigns for Good Reason (each, as defined in the employment agreements), in each case, other than during the period commencing three months prior to and ending 18 months following a change in control, the named executive officer will be eligible to receive: (i) a lump sum cash payment equal to 1x, in the case of our Chief Executive Officer, or 0.75x, in the case of our other named executive officers, the sum of the executive’s annual base salary and target annual bonus; (ii) payment or reimbursement of COBRA premiums for 12 months, in the case of our Chief Executive Officer, or nine months, in the case of our other named executive officers; and (iii) at the discretion of the Board or the Compensation Committee, 12 months’ accelerated vesting of equity awards, in the case of our Chief Executive Officer, or 9 months’ accelerated vesting of equity awards, in the case of our other named executive officers.

In addition, in the event the named executive officer is terminated without Cause or resigns for Good Reason, in each case, during the period commencing three months prior to and ending 18 months following a change in control, the named executive officer will be eligible to receive: (i) a lump sum cash payment equal to 2x, in the case of our Chief Executive Officer, or 1x, in the case of our other named executive officers, the sum of the executive’s annual base salary and target annual bonus; (ii) payment or reimbursement of COBRA premiums for 18 months, in the case of our Chief Executive Officer, or 12 months, in the case of our other named executive officers; and (iii) full accelerated vesting of all equity awards. All severance payments and benefits under the employment agreements are subject to the executive’s execution of a release of claims against us.

The following table provides information concerning the estimated payments and benefits that would be provided in the circumstances described above for each of our named executive officers. Except where otherwise noted, payments and benefits are estimated assuming that the triggering event took place on December 31, 2022, and a fair market value of our common stock on December 31, 2022 of $23.82 per share (determined based on the closing trading price of a share of our common stock on December 30, 2022). There can be no assurance that a triggering event would produce the same or similar results as those estimated below if such event occurs on any other date.

43

CEO Pay Ratio

As required by Section 953(b) of Dodd- Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are providing information about the relationship of the annual total compensation of our employees and the annual total compensation of our CEO. For 2022, our last completed fiscal year, the total compensation of our CEO was approximately 25 times the median total compensation in 2022 of all of our other employees. The median of the annual total compensation of all our employees (other than our CEO) was $284,388 and the annual total compensation of our CEO was $7,217,839, as included in the “Summary Compensation Table” above.

In accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, we have identified the median employee as of October 31, 2022 by: (i) aggregating for each applicable employee: (a) annual base salary for salaried employees (or annual scheduled wages for hourly employees), (b) target cash incentive opportunity for fiscal year 2022, and (c) the estimated grant date fair value of equity awards granted during fiscal year 2022, and (ii) ranking this aggregated compensation measure for our employees from lowest to highest. This calculation was performed for all employees employed by us as of October 31, 2022, excluding the Chief Executive Officer, whether employed on a full-time or part-time basis. In making this determination, we annualized the compensation of employees who were employed by the Company for less than the entire fiscal year. This compensation measure was consistently applied to all employees included in the calculation and reasonably reflects the annual compensation of employees.
