PROXY STATEMENT
FOR THE 2023 ANNUAL MEETING OF STOCKHOLDERS

GENERAL INFORMATION

Who is soliciting my vote?

Our board of directors, or Board of Directors or Board, is soliciting your vote for the Annual Meeting for the purposes discussed in this proxy statement and the accompanying Notice of 2023 Annual Meeting of Stockholders.

Why am I receiving these materials?

We have made these proxy materials available to you to provide you with information regarding the proposals on which you may vote at the Annual Meeting. These proxy materials are available on the Internet, and we will, upon your request, deliver print versions of these proxy materials to you by mail, each as described in the following questions and answers. You are invited to attend the virtual Annual Meeting and we are requesting you to vote on the proposals described in this proxy statement.

Can I access these materials on the Internet instead of receiving paper copies?

Yes, stockholders may access this proxy statement, our Annual Report to Stockholders on Form 10-K for the year ended December 31, 2022, and the Notice of Internet Availability of Proxy Materials, or the Notice, via the Internet at www.investorvote.com/SWTX. We are furnishing the proxy materials to our stockholders on the Internet in lieu of mailing a printed copy of our proxy materials. You will not receive a printed copy of the proxy materials unless you request one. If you would like to receive a printed or electronic copy of the proxy materials, free of charge, you should follow the instructions for requesting such materials in the Notice. The Notice instructs you as to how you may access and review all of the important information contained in the proxy materials on the Internet or request a printed copy of those materials. The Notice also instructs you as to how you may vote your proxy.

When is the record date for the Annual Meeting?

The record date for determination of stockholders entitled to receive notice of and vote at the Annual Meeting is the close of business on March 30, 2023.

How many votes can be cast by all stockholders?

There were 62,523,438 shares of our common stock, par value $0.0001 per share, outstanding on March 30, 2023, all of which are entitled to vote with respect to all matters to be acted upon at the Annual Meeting. Each stockholder of record is entitled to one vote for each share of our common stock held by such stockholder.

How do I vote?

If you are a stockholder of record, there are several ways for you to vote your shares.

•

By Telephone. You may vote using a touch-tone telephone by calling 1-800-652-8683, 24 hours a day, seven days a week. You will need the 16-digit control number included on your proxy card.

•

By Internet. You may vote at www.investorvote.com/SWTX, 24 hours a day, seven days a week. You will need the 16-digit control number included on your proxy card.

•

By Mail. You may vote by mail by completing, signing and dating the proxy card you received by mail and returning it in the enclosed prepaid envelope.

•

During the Annual Meeting. You may vote during the Annual Meeting by attending the virtual Annual Meeting and executing a ballot in accordance with the procedures described at the Annual Meeting.

2

Telephone, Internet and Mail voting for stockholders of record will be available until the closing of polls at the virtual Annual Meeting in order to be counted at the Annual Meeting. If the Annual Meeting is adjourned or postponed, these deadlines may be extended.

The voting deadlines and availability of telephone and Internet voting for beneficial owners of shares held in “street name” will depend on the voting processes of the organization that holds your shares. Therefore, we urge you to carefully review and follow the voting instruction card and any other materials that you receive from that organization. If you hold your shares of SpringWorks Therapeutics common stock in multiple accounts, you should vote your shares as described in each set of proxy materials you receive.

How do I revoke my proxy?

You may revoke your proxy by (i) following the instructions on the Notice and entering a new vote by mail that we receive before the start of the virtual Annual Meeting or over the Internet by the cutoff time of the closing of polls at the virtual Annual Meeting, (ii) attending and voting at the Annual Meeting (although attendance at the Annual Meeting will not in and of itself revoke a proxy), or (iii) by filing an instrument in writing revoking the proxy or another duly executed proxy bearing a later date with our Corporate Secretary. Any written notice of revocation or subsequent proxy card must be received by our Corporate Secretary prior to the taking of the vote at the Annual Meeting. Such written notice of revocation or subsequent proxy card should be hand delivered to our Corporate Secretary or sent to our principal executive offices at SpringWorks Therapeutics, Inc., 100 Washington Blvd, Stamford, Connecticut 06902, Attention: Corporate Secretary.

If a broker, bank, or other nominee holds your shares, you must contact such broker, bank, or nominee in order to find out how to change your vote.

How is a quorum reached?

Our Amended and Restated Bylaws, as amended, or bylaws, provide that a majority of the issued and outstanding shares of our common stock entitled to vote on any matters, present in person or represented by proxy, will constitute a quorum for the transaction of business at the Annual Meeting. Shares present virtually during the Annual Meeting will be considered shares of common stock represented in person at the meeting.

Shares held of record by stockholders or brokers, banks or other nominees who do not return a signed and dated proxy or attend the Annual Meeting virtually will not be considered present or represented at the Annual Meeting and will not be counted in determining the presence of a quorum. Votes withheld, abstentions and broker non-votes will be counted for purposes of determining whether a quorum is present for the transaction of business at the meeting.

If a quorum is not present, the meeting may be adjourned until a quorum is obtained.

How is the vote counted?

Votes cast by proxy or online at the Annual Meeting will be counted by the persons appointed by the Company to act as tabulators for the meeting. The tabulators will count all votes FOR, AGAINST and WITHHELD, abstentions and broker non-votes, as applicable, for each matter to be voted on at the Annual Meeting. A broker non-vote occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner.

Under our bylaws, any proposal other than an election of directors is decided by a majority of the votes properly cast for and against such proposal, except where a larger vote is required by law or by our Amended and Restated Certificate of Incorporation, or certificate of incorporation, or bylaws. Abstentions and broker “non-votes” are not included in the tabulation of the voting results with respect to any such proposal and, therefore, do not have an impact on such proposals. A broker “non-vote” occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner.

3

If your shares are held in “street name” by a brokerage firm, your brokerage firm is required to vote your shares according to your instructions. If you do not give instructions to your brokerage firm, the brokerage firm will still be able to vote your shares within its discretion. Under the rules of the New York Stock Exchange, which are also applicable to Nasdaq-listed companies, brokers, banks and other securities intermediaries that are subject to New York Stock Exchange rules may use their discretion to vote your “uninstructed” shares on matters considered to be “routine” under New York Stock Exchange rules but not with respect to “non-routine” matters. Each of Proposal No. 1 and No. 3 is considered to be “non-routine” item, or a “non-discretionary item,” thus your broker, bank or other agent may not vote your shares on those proposals in the absence of your voting instructions. If you do not instruct your broker how to vote with respect to these proposals, those votes will be counted as broker “non-votes.” Proposal No. 2 is considered to be “routine” item, or a “discretionary item,” and thus if you do not return voting instructions to your broker, your shares may be voted by your broker in its discretion. Votes withheld, abstentions and broker non-votes will be counted towards the quorum requirement. Accordingly, we do not anticipate that there will be any broker non-votes on this proposal; however, any broker non-votes will not be counted as “votes cast” and will therefore have no effect on Proposal No. 2.

Our charter and by-laws do not provide for cumulative voting in the election of directors. Under our by-laws, directors are elected by plurality vote. This means that the two director nominees via Proposal No. 1 receiving the highest number of affirmative votes properly cast will be elected as directors. You may vote for all of the director nominees, withhold authority to vote your shares for all of the director nominees or withhold authority to vote your shares with respect to any one or more of the director nominees. Withholding authority to vote your shares with respect to one or more director nominees will have no effect on the election of those nominees. Broker non-votes are not considered votes cast and will have no effect on the election of the nominees.

To elect our directors and approve the other proposals being considered at the Annual Meeting, the voting requirements are as follows:

Proposal	Vote Required	Discretionary Voting Permitted?
Election of Directors	Plurality	No
Ratification of Independent Registered Public Accounting Firm	Majority	Yes
Non-Binding Advisory Vote to Approve the Compensation of Our Named Executive Officers	Majority	No

“Discretionary Voting Permitted” means that brokers will have discretionary voting authority with respect to shares held in street name for their clients, even if the broker does not receive voting instructions from their client.

“Majority” means a majority of the votes properly cast for and against such matter.

“Plurality” means a plurality of the votes properly cast on such matter. For the election of directors, the two nominees receiving the highest number of affirmative votes properly cast will be elected as directors.

Who pays the cost for soliciting proxies?

We are making this solicitation and will pay the entire cost of preparing and distributing the Notice and our proxy materials and soliciting votes. If you choose to access the proxy materials or vote over the Internet, you are responsible for any Internet access charges that you may incur. Our officers and employees may, without compensation other than their regular compensation, solicit proxies through further mailings, personal conversations, facsimile transmissions, e-mails, or otherwise. We have hired Computershare Limited to assist us in the distribution of proxy materials and the solicitation of votes described above. Proxy solicitation expenses that we will pay include those for preparing, mailing, returning, and tabulating the proxies.

How may stockholders submit matters for consideration at an annual meeting?

Any stockholder who meets the requirements of the proxy rules under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), may submit proposals to the Board of Directors to be presented at

4

an annual meeting. The required notice must be submitted in writing and received by our Corporate Secretary at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary of the preceding year’s annual meeting. However, in the event that the date of the Annual Meeting is advanced by more than 30 days, or delayed by more than 60 days, from the first anniversary of the preceding year’s annual meeting, or if no annual meeting were held in the preceding year, a stockholder’s notice must be so received no earlier than the 120th day prior to such annual meeting and not later than the close of business on the later of (i) the 90th day prior to such annual meeting and (ii) the tenth day following the day on which public disclosure of the date of such annual meeting was first made. For stockholder proposals to be brought before the next annual meeting, the required notice must be received by our Corporate Secretary at our principal executive offices at the address set forth above no earlier than January 25, 2024 and no later than February 24, 2024.

In addition, any stockholder proposal intended to be included in the proxy statement for the next annual meeting of our stockholders in 2024 must also satisfy the requirements of SEC Rule 14a-8 under the Exchange Act and be received no later than December 9, 2023, which is 120 days before the first anniversary of the date on which the Company’s proxy materials for the Annual Meeting were first made available to stockholders. Any stockholder proposals submitted outside the processes of SEC Rule 14a-8, or received after December 9, 2023, will be considered untimely. In addition, to comply with the SEC’s universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than our nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 25, 2024. If the date of the annual meeting is moved by more than 30 days from the date contemplated at the time of the previous year’s proxy statement, then notice must be received within a reasonable time before we begin to print and send proxy materials. If that happens, we will publicly announce the deadline for submitting a proposal in a press release or in a document filed with the SEC. Stockholder proposals and the required notice submitted by mail should be addressed to our Corporate Secretary at our principal executive offices at the address set forth above.

How can I know the voting results?

We plan to announce preliminary voting results at the Annual Meeting and will publish final results in a Current Report on Form 8-K to be filed with the SEC within four business days following the Annual Meeting.

Why is the Annual Meeting a virtual, online meeting?

We believe that hosting a virtual meeting will facilitate shareholder attendance and participation by enabling shareholders to participate from any location around the world and improves our ability to communicate more effectively with our shareholders. We have designed the virtual meeting to provide substantially the same opportunities to participate as you would have at an in-person meeting. We are providing opportunities to submit questions prior to the meeting, to enable us to address appropriate questions at the Annual Meeting.

PROPOSAL NO. 1 — ELECTION OF CLASS I DIRECTORS

Our Board of Directors currently consists of seven members. In accordance with the terms of our certificate of incorporation and bylaws, our Board of Directors is divided into three classes, Class I, Class II and Class III, with members of each class serving staggered three-year terms. The members of the classes are divided as follows:

•

the Class I directors are Saqib Islam, J.D. and Carlos Albán, and their terms will expire at the Annual Meeting;

•

the Class II directors are Freda Lewis-Hall, M.D., DFAPA and Jeffrey Schwartz, M.B.A., and their terms will expire at the annual meeting of stockholders to be held in 2024; and

•

the Class III directors are Alan Fuhrman, Julie Hambleton, M.D., and Daniel S. Lynch, M.B.A., and their terms will expire at the annual meeting of stockholders to be held in 2025.

Upon the expiration of the term of a class of directors, directors in that class will be eligible to be elected for a new three-year term at the annual meeting of stockholders in the year in which their term expires.

Our certificate of incorporation and bylaws provide that the authorized number of directors may be changed only by resolution of our Board of Directors. Our certificate of incorporation also provides that our directors may be removed only for cause by the affirmative vote of the holders of at least two-thirds (2/3) of the outstanding shares then entitled to vote in an annual election of directors, and that any vacancy on our Board of Directors, including a vacancy resulting from an enlargement of our Board of Directors, may be filled only by vote of a majority of our directors then in office.

Our Board of Directors has nominated Saqib Islam, J.D. and Carlos Albán for election as the Class I directors at the Annual Meeting. The nominees are presently directors and have indicated a willingness to continue to serve as directors, if elected. If the nominees become unable or unwilling to serve, however, the proxies may be voted for a substitute nominee selected by our Board of Directors.

Our Board selection process places emphasis on identifying members who will further the interests of our stockholders through their established record of professional accomplishment, their ability to contribute positively to the collaborative culture among Board members, and their knowledge of our business and understanding of the competitive landscape. Our Company policy commits us to the values of diversity, and thus, the diversity of our Board is an important consideration in the director nomination and selection process. Our nominating and corporate governance committee assesses diversity in connection with the annual nomination process as well as in new director searches. Our seven directors range in age from 44 to 68 and include two women and three ethnically diverse persons.

We believe that Mr. Fuhrman is qualified to serve on our Board of Directors based on his experience as the Chief Financial Officer of pharmaceutical companies, his prior service on the board of a public biotechnology company and his financial expertise and experience with public company accounting.

CORPORATE GOVERNANCE

Director Nomination Process

Our nominating and corporate governance committee is responsible for identifying individuals qualified to serve as directors, consistent with criteria approved by our Board of Directors, and recommending such persons to be nominated for election as directors, except where we are legally required by contract, law or otherwise to provide third parties with the right to nominate.

The process followed by our nominating and corporate governance committee to identify and evaluate director candidates includes requests for recommendations from members of the Board of Directors, our executive officers, third-party search firms and other sources deemed appropriate by the committee, meetings from time to time to evaluate biographical information and background material relating to potential candidates, and interviews of selected candidates by management, members of the committee and our Board of Directors. The minimum qualifications, qualities and skills that a committee-recommended nominee for a position on our Board of Directors must satisfy are set forth in our corporate governance guidelines, including experience at a strategic or policymaking level, accomplishments in his or her field, being well-regarded in the community, having integrity, having sufficient time and availability to devote to the affairs of SpringWorks Therapeutics, and to the extent such nominee serves or has previously served on other boards, contributions to such boards. In addition, while we have no formal policy regarding Board diversity, the overall diversity of our Board is an important consideration in the director nomination and selection process. Our nominating and corporate governance committee assesses diversity in connection with the annual nomination process as well as in new director searches.

Stockholders may recommend individuals to the nominating and corporate governance committee for consideration as potential director candidates. Any such proposals should be submitted to our Corporate Secretary at our principal executive offices no later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the one-year anniversary of the date of the preceding year’s annual meeting and should include appropriate biographical and background material to allow the nominating and corporate governance committee to properly evaluate the potential director candidate and the number of shares of our stock beneficially owned by the stockholder proposing the candidate. In addition, to comply with the universal proxy rules, stockholders who wish to solicit proxies in support of director nominees other than our nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 25, 2024. Stockholder proposals should be addressed to SpringWorks Therapeutics, Inc., 100 Washington Blvd, Stamford, Connecticut 06902, Attention: Corporate Secretary. Assuming that biographical and background material has been provided on a timely basis in accordance with our bylaws and the stockholders have otherwise complied with the requirements set forth in our bylaws, any recommendations received from stockholders will be evaluated in the same manner as potential nominees proposed by the nominating and corporate governance committee. If our Board of Directors determines to nominate a stockholder-recommended candidate and recommends his or her election, then his or her name will be included on our proxy card for the next annual meeting of stockholders. See “Stockholder Proposals” for a discussion of submitting stockholder proposals.

Director Independence

Applicable Nasdaq Stock Market LLC, or Nasdaq, rules require a majority of a listed company’s Board of Directors to be comprised of independent directors. In addition, the Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent and that audit committee members also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act and that compensation committee members satisfy independence criteria set forth in Rule 10C-1 under the Exchange Act. Under applicable Nasdaq rules, a director will only qualify as an “independent director” if, in the opinion of the listed company’s Board of Directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the Board of Directors, or any other Board committee, accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company

12

or any of its subsidiaries or otherwise be an affiliated person of the listed company or any of its subsidiaries. In addition, in affirmatively determining the independence of any director who will serve on a company’s compensation committee, Rule 10C-1 under the Exchange Act requires that a company’s Board of Directors must consider all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including: the source of compensation to the director, including any consulting, advisory or other compensatory fee paid by such company to the director, and whether the director is affiliated with the company or any of its subsidiaries or affiliates.

Our Board of Directors has determined that all members of the Board of Directors, except Saqib Islam, are independent directors, including for purposes of the rules of Nasdaq and the SEC. In making such independence determination, our Board of Directors considered the relationships that each non-employee director has with us and all other facts and circumstances that our Board of Directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. In considering the independence of the directors listed above, our Board of Directors considered the association of our directors with the holders of more than 5% of our common stock. There are no family relationships among any of our directors or executive officers. Mr. Islam is not an independent director under these rules because he is our Chief Executive Officer.

Board Committees

Our Board of Directors has established an audit committee, a compensation committee, a nominating and corporate governance committee, and a research and development committee. Each of the audit committee, compensation committee, nominating and corporate governance committee, and research and development committee operates under a charter that satisfies the applicable standards of the SEC and Nasdaq. Each such committee reviews its respective charter at least annually. A current copy of the charter for each of the audit committee, compensation committee, nominating and corporate governance committee, and research and development committee is posted on the corporate governance section of our website, https://ir.springworkstx.com/investor-relations/corporate-governance.

Audit Committee

Alan Fuhrman, Julie Hambleton, and Jeffrey Schwartz serve on the audit committee, which is chaired by Mr. Fuhrman. Our Board of Directors has determined that each of Mr. Fuhrman, Dr. Hambleton and Mr. Schwartz are “independent” for audit committee purposes as that term is defined in the rules of the SEC and the applicable Nasdaq rules, and that all members of the committee have sufficient knowledge in financial and auditing matters to serve on the audit committee. Our Board of Directors has determined that Mr. Schwartz is independent even though he fell outside the “safe harbor” definition set forth in Rule 10A-3(e)(1)(ii) under the Exchange Act because he is a manager of Bain Capital Life Sciences Investors, LLC, which is the general partner of BCSW, L.P., which, owned in excess of 10% of our common stock. Among other things, our Board of Directors considered Mr. Schwartz’s history of service and the percentage of common stock held by others, and it determined that he is not an “affiliated person” of the Company who would be ineligible to serve on our audit committee. Our Board of Directors has designated Mr. Fuhrman as an “audit committee financial expert,” as defined under the applicable rules of the SEC. During the fiscal year ended December 31, 2022, the audit committee met six (6) times. The report of the audit committee is included in this proxy statement under “Report of the Audit Committee.” The audit committee’s responsibilities include:

All audit and non-audit services, other than de minimis non-audit services, to be provided to us by our independent registered public accounting firm must be approved in advance by our audit committee.

Compensation Committee

Daniel S. Lynch, Carlos Albán and Jeffrey Schwartz serve on the compensation committee, which is chaired by Mr. Lynch. Our Board of Directors has determined that each of Messrs. Lynch, Albán and Schwartz is “independent” as defined in the applicable Nasdaq rules for purposes of serving on the compensation committee. During the fiscal year ended December 31, 2022, the compensation committee met nine (9) times. The compensation committee’s responsibilities include:

•

annually reviewing and recommending to the Board of Directors corporate goals and objectives relevant to the compensation of our Chief Executive Officer;

•

evaluating the performance of our Chief Executive Officer in light of such corporate goals and objectives and recommending to the Board of Directors the compensation of our Chief Executive Officer;

•

Nominating and Corporate Governance Committee

Freda Lewis-Hall, Carlos Albán and Alan Fuhrman serve on the nominating and corporate governance committee, which is chaired by Dr. Lewis-Hall. Our Board of Directors has determined that Dr. Lewis-Hall, Mr. Albán and Mr. Fuhrman are “independent” as defined in the applicable Nasdaq rules for purposes of serving on the nominating and corporate governance committee. During the fiscal year ended December 31, 2022, the nominating and corporate governance committee met three (3) times. The nominating and corporate governance committee’s responsibilities include:

•

developing and recommending to the Board of Directors criteria for Board and committee membership;

•

establishing procedures for identifying and evaluating Board of Director candidates, including nominees recommended by stockholders;

•

reviewing the size and composition of the Board of Directors to ensure that it is composed of members containing the appropriate skills and expertise to advise us;

•

exercising oversight over environmental and social governance matters; and

•

The nominating and corporate governance committee considers candidates for Board of Director membership suggested by its members and the Chief Executive Officer. Additionally, in selecting nominees for directors, the nominating and corporate governance committee will review candidates recommended by stockholders in the same manner and using the same general criteria as candidates recruited by the committee and/or recommended by our Board of Directors. Any stockholder who wishes to recommend a candidate for consideration by the committee as a nominee for director should follow the procedures described later in this proxy statement under the heading “Stockholder Proposals.” The nominating and corporate governance committee will also consider whether to nominate any person proposed by a stockholder in accordance with the provisions of our bylaws relating to stockholder nominations as described later in this proxy statement under the heading “Stockholder Proposals.”

Identifying and Evaluating Director Nominees.   Our Board of Directors is responsible for filling vacancies on our Board of Directors and for nominating candidates for election by our stockholders each year in the class of directors whose term expires at the relevant annual meeting. The Board of Directors delegates the selection and nomination process to the nominating and corporate governance committee, with the expectation that other members of the Board of Directors, and of management, will be requested to take part in the process as appropriate.

Generally, the nominating and corporate governance committee identifies candidates for director nominees in consultation with management, through the use of search firms or other advisors, through the recommendations submitted by stockholders or through such other methods as the nominating and corporate governance committee deems to be helpful to identify candidates. Once candidates have been identified, the nominating and corporate governance committee confirms that the candidates meet all of the minimum qualifications for director nominees established by the nominating and corporate governance committee.

15

The nominating and corporate governance committee may gather information about the candidates through interviews, detailed questionnaires, comprehensive background checks or any other means that the nominating and corporate governance committee deems to be appropriate in the evaluation process. The nominating and corporate governance committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of our Board of Directors. Based on the results of the evaluation process, the nominating and corporate governance committee recommends candidates for the Board of Directors’ approval to fill a vacancy or as director nominees for election to the Board of Directors by our stockholders each year in the class of directors whose term expires at the relevant annual meeting.

Research and Development Committee

At present and since the resignation of Stephen Squinto, Ph.D. from the Board of Directors and from the research and development committee in July 2022, Julie Hambleton serves as the sole member of the research and development committee, which is chaired by Dr. Hambleton. During the fiscal year ended December 31, 2022, the research and development committee met four (4) times. The research and development committee’s responsibilities include:

•

providing feedback and analysis to Company management and personnel regarding, and assisting the Board of Directors regarding its oversight of, pre-clinical and clinical decision-making;

•

evaluating and advising the Board of Directors regarding the Company’s progress in achieving its short-term and long-term strategic research and development goals and objectives;

•

evaluating and advising the Board of Directors regarding the quality, direction and competitiveness of the Company’s research and development programs;

•

evaluating potential in-licensing, acquisition and collaboration opportunities as requested by the Company; and

•

providing recommendations regarding key discovery and development strategies, as requested by the Board of Directors from time to time, to align with business needs of the Company.

Board and Committee Meetings Attendance

The full Board of Directors met five (5) times during 2022. During 2022, each member of the Board of Directors attended in person or participated in 75% or more of the aggregate of (i) the total number of meetings of the Board of Directors (held during the period for which such person has been a director) and (ii) the total number of meetings held by all committees of the Board of Directors on which such person served (during the periods that such person served).

Director Attendance at Annual Meeting of Stockholders

Directors are responsible for attending the annual meeting of stockholders to the extent practicable. With the exception of Carlos Albán, who was appointed to the Board of Directors in July 2022, all the members of the Board of Directors attended the 2022 annual meeting of stockholders that was held on May 19, 2022.

Policy on Trading, Pledging and Hedging of Company Stock

Certain transactions in our securities (such as purchases and sales of publicly traded put and call options, and short sales) create a heightened compliance risk or could create the appearance of misalignment between management and stockholders. In addition, securities held in a margin account or pledged as collateral may be sold without consent if the owner fails to meet a margin call or defaults on the loan, thus creating the risk that a sale may occur at a time when an officer or director is aware of material, non-public information or otherwise is not permitted to trade in Company securities. Our insider trading policy expressly prohibits short sales and derivative transactions of our stock, including for purposes of hedging investment risk, by our executive officers, directors, employees and certain designated consultants and contractors, including short sales of our securities. Our insider trading policy expressly prohibits purchases

16

or sales of puts, calls, or other derivative securities of the Company or any derivative securities that provide the economic equivalent of ownership. In addition, such policy prohibits the pledging of the Company’s equity as collateral for a loan.

Code of Business Conduct and Ethics

We have adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A current copy of the code is posted on the corporate governance section of our website, which is located at https://ir.springworkstx.com/investor-relations/​corporate-governance. If we make any substantive amendments to, or grant any waivers from, the code of business conduct and ethics for any officer or director, we will disclose the nature of such amendment or waiver on our website or in a current report on Form 8-K.

Board Leadership Structure and Board’s Role in Risk Oversight

Currently, the role of Chairman of the Board of Directors is separated from the role of Chief Executive Officer. We believe that separating these positions allows our Chief Executive Officer to focus on our day-to-day business, while allowing the Chairman of the Board of Directors to lead the Board of Directors in its fundamental role of providing advice to, and independent oversight of, management. Our Board of Directors recognizes the time, effort, and energy that the Chief Executive Officer is required to devote to his position in the current business environment, as well as the commitment required to serve as our Chairman, particularly as the Board of Directors’ oversight responsibilities continue to grow. While our bylaws and our corporate governance guidelines do not require that our Chairman and Chief Executive Officer positions be separate, our Board of Directors believes that having separate positions is the appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance.

Risk is inherent to every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including risks relating to our financial condition, development and future commercialization activities, operations, strategic direction, and intellectual property. Management is responsible for the day-to-day management of risks we face, while our Board of Directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our Board of Directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

The role of the Board of Directors in overseeing the management of our risks is conducted primarily through committees of the Board of Directors, as disclosed in the descriptions of each of the committees above and in the charters of each of the committees. The full Board of Directors (or the appropriate Board committee in the case of risks that are under the purview of a particular committee) discusses with management our major risk exposures, their potential impact on us, and the steps we take to manage them. When a committee of the Board of Directors is responsible for evaluating and overseeing the management of a particular risk or risks, the chairman of the relevant committee reports on the discussion to the full Board of Directors during the committee reports portion of the next Board meeting. This enables the Board of Directors and its committees to coordinate the risk oversight role, particularly with respect to risk interrelationships.

Environmental, Social and Governance (ESG) Strategy

We recognize the importance of sustainability, a diverse workforce, and a commitment to the communities we serve. We believe that a sustainable business strategy in driving the long-term growth of our business requires the integration of ESG considerations and we continue to evaluate our ESG strategy to ensure that we are focused on the issues that are most impactful to our business and our stockholders. We believe that delivering sustainable, long-term growth rests on strong governance at every level of our business. Our Board operates with integrity and transparency as it oversees corporate governance practices to serve the interests of our stockholders and better align the interests of directors and management with those of our stockholders. Some key attributes of our governance framework include:

17

•

the development (and recommendation thereof) of criteria for Board and committee membership, including the assessment of diversity;

•

active stockholder engagement;

•

annual board self-assessment process; and

•

risk oversight by the Board and committees.

Communication with the Directors of SpringWorks Therapeutics

Any interested party with concerns about the Company may report such concerns to the Board of Directors or the Chairman of our Board of Directors, or Chairman, or the nominating and corporate governance committee, by submitting a written communication to the attention of such directors at the following address:

c/o SpringWorks Therapeutics, Inc.
100 Washington Blvd
Stamford, CT 06902

You may submit your concern anonymously or confidentially by postal mail. You may also indicate whether you are a stockholder, customer, supplier, or other interested party.

A copy of any such written communication may also be forwarded to SpringWorks Therapeutics’ General Counsel and a copy of such communication may be retained for a reasonable period of time. The Chairman may discuss the matter with SpringWorks Therapeutics’ legal counsel, with independent advisors, with non-management directors, or with SpringWorks Therapeutics’ management, or may take other action or no action as the Chairman determines in good faith, using reasonable judgment, and applying his or her own discretion.

Communications may be forwarded to other directors if they relate to important substantive matters and include suggestions or comments that may be important for other directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances, and matters as to which we tend to receive repetitive or duplicative communications.

The audit committee oversees the procedures for the receipt, retention, and treatment of complaints received by SpringWorks Therapeutics regarding accounting, internal accounting controls, or audit matters, and the confidential, anonymous submission by employees of concerns regarding questionable accounting, internal accounting controls or auditing matters.

DIRECTOR COMPENSATION

Role of Compensation Consultant

Each year, when establishing the appropriate level of compensation for our non-employee directors, our compensation committee considers relevant market data received from our independent compensation consultant for companies in our peer group.

Non-Employee Director Compensation Policy in effect from February 22, 2022 through February 22, 2023

From and after February 22, 2022, through February 22, 2023, each of our non-employee directors participated in our then-current Amended and Restated Non-Employee Director Compensation Policy, or Director Plan. All 2022 compensation for our non-employee directors was paid in accordance with this policy. Pursuant to such policy, each of our non-employee directors was entitled to an annual cash fee of $45,000. The non-executive chairperson of our Board of Directors was entitled to receive an additional annual fee of $30,000. In addition, members of our committees of the Board were entitled to receive additional compensation as follows: (i) each non-chairperson member of the audit committee was entitled to receive an annual fee of $10,000, while the chairperson of the audit committee was entitled to receive an annual fee $20,000; (ii) each non-chairperson member of the compensation committee was entitled to receive an annual fee of $7,500, while the chairperson of the compensation committee was entitled to receive an annual fee of $15,000; (iii) each non-chairperson member of the nominating and corporate governance committee was entitled to receive an annual fee of $5,000, while the chairperson of the nominating and corporate governance committee was entitled to receive an annual fee of $10,000 and (iv) each non-chairperson member of the research and development committee was entitled to receive an annual fee of $7,500 and the chairperson of the research and development committee was entitled to receive an annual fee of $15,000. In addition, each non-employee director serving on our Board of Directors was entitled to receive a one-time equity grant with a value of $873,000 upon initial appointment or election to the Board, with two-thirds (2/3) of the value of such grant (calculated using the Black-Scholes option pricing model) provided in the form of stock options, which vest in equal monthly installments over three (3) years, and one-third (1/3) of such value provided in the form of restricted stock awards, which vest in equal annual installments over three (3) years, subject to continued service on the Board of Directors through each vesting date. Further, immediately following each annual meeting of the Company’s stockholders, each continuing non-employee director serving on our Board of Directors received an annual equity grant that had a value equivalent to $512,000, with two-thirds (2/3) of the value of such grant (calculated using the Black-Scholes option pricing model) provided in the form of stock options and one-third (1/3) of such value in the form of restricted stock awards, with such annual grant vesting on the earlier of the one-year anniversary of the grant date and the Company’s next annual meeting of stockholders following such grant, subject to continued service on the Board through such date. All of the foregoing equity grants become immediately exercisable upon the death or permanent disability of a non-employee director or upon a “sale event” ​(as defined in the Company’s Amended and Restated 2019 Stock Option and Incentive Plan, or 2019 Plan).

Non-Employee Director Compensation Policy in effect as of February 23, 2023

In 2022, our compensation committee continued to retain the services of Aon as its compensation consultant to advise on, among other things, director compensation matters. On February 23, 2023, based on a review of a peer group analysis prepared by Aon to benchmark our director compensation levels, the compensation committee recommended and the Board further amended the Director Plan, effective immediately as of such date, to make certain adjustments to our non-employee director compensation to align it with the competitive market and be used for determining director compensation from and after such date. These adjustments include the following:

•

increasing the annual retainer for non-executive chairperson of the Board from $30,000 to $35,000;

•

increasing the value of the initial equity grant upon initial appointment or election to the Board from $873,000 to $900,000; and

•

decreasing the value of the annual equity grant from $512,000 to $450,000.

19

All of the foregoing equity grants become immediately vested or exercisable, as the case may be, upon the death or permanent disability of a non-employee director or upon a “sale event” ​(as defined in the 2019 Plan).

Under our Director Plan, effective as February 23, 2023, the fees paid to non-employee directors for service on the Board of Directors and for service on each committee of the Board of Directors on which the director is a member are as follows:

​	Annual Retainer
Board of Directors:	​	​	​
All nonemployee members	​	$	45,000
Additional retainer for Non-Executive Chairman of the Board	​	$	35,000
Audit Committee:	​	​	​
Chairman	​	$	20,000
Non-Chairman members	​	$	10,000
Compensation Committee:	​	​	​
Chairman	​	$	15,000
Non-Chairman members	​	$	7,500
Nominating and Corporate Governance Committee:	​	​	​
Chairman	​	$	10,000
Non-Chairman members	​	$	5,000
Research and Development Committee:	​	​	​
Chairman	​	$	15,000
Non-Chairman members	​	$	7,500

The aforementioned changes to our non-employee director compensation pursuant to our Director Plan shall be applicable to all non-employee directors newly appointed from and after this Annual Meeting and all current non-employee directors who continue their service on the Board of Directors after this Annual Meeting.

We also reimburse our non-employee directors for reasonable travel and out-of-pocket expenses incurred in connection with attending our Board of Directors and committee meetings.

This policy is intended to provide a total compensation package that enables us to attract and retain qualified and experienced individuals to serve as directors and to align our directors’ interests with those of our stockholders.

Other Compensation Details

The aggregate amount of cash and equity compensation paid to any non-employee director in a calendar year may not exceed $1,600,000 for the first year of service and $800,000 for each year of service thereafter (or such other limits as may be set forth in the 2019 Plan or any similar provision of a successor plan). Employee directors receive no additional compensation for their service as a director.

PROPOSAL NO. 2 — RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS SPRINGWORKS THERAPEUTICS’ INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2023

SpringWorks Therapeutics’ stockholders are being asked to ratify the appointment by the audit committee of the Board of Directors of Ernst & Young LLP as SpringWorks Therapeutics’ independent registered public accounting firm for the fiscal year ending December 31, 2023. Ernst & Young LLP has audited the Company’s financial statements for each fiscal year since our inception in 2017.

Stockholder approval is not required to appoint Ernst & Young LLP as SpringWorks Therapeutics’ independent registered public accounting firm. However, the Board of Directors believes that submitting the appointment of Ernst & Young LLP to the stockholders for ratification is good corporate governance. If the stockholders do not ratify this appointment, the audit committee will reconsider whether to retain Ernst & Young LLP. Even if the selection of Ernst & Young LLP is ratified, the audit committee may, at its discretion, direct the appointment of a different independent registered public accounting firm at any time it decides that such a change would be in the best interest of SpringWorks Therapeutics and its stockholders.

A representative of Ernst & Young LLP is expected to be present at the Annual Meeting and will have an opportunity to make a statement if he or she desires to do so and to respond to appropriate questions from our stockholders.

SpringWorks Therapeutics incurred the following fees from Ernst & Young LLP for the audit of the consolidated financial statements and for other services provided during the years ended December 31, 2022 and 2021.

​	2022			2021
Audit fees(1)	​	$	1,110,000	​	$	866,127
Audit-related fees	​	​	—	​	​	—
Tax fees(2)	​	​	48,000	​	​	304,510
All other fees	​	​	—	​	​	—
Total fees	​	$	1,158,000	​	$	1,170,637

(1)

Audit fees in 2022 include fees related to the audit of our annual financial statements, the review of our interim financial statements included in our quarterly reports on Form 10-Q, and services in connection with the Company’s private placements and at the money offerings during 2022. Audit fees in 2021 include fees related to the audit of our annual financial statements, the review of our interim financial statements included in our quarterly reports on Form 10-Q, and services in connection with the Company’s sales agreement with Cowen and Company, LLC, pursuant to which we may issue and sell shares in ‘at the market’ offerings, which was instituted in February 2021.

(2)

Tax fees consist of fees for tax compliance, advice and tax services.

Audit Committee Pre-approval Policy and Procedures

Our audit committee has adopted a policy relating to the approval of all audit and non-audit services that are to be performed by our independent registered public accounting firm, which policy became effective as of August 7, 2019. This policy provides that we will not engage our independent registered public accounting firm to render audit or non-audit services unless the service is specifically approved in advance by our audit committee or the engagement is entered into pursuant to the pre-approval procedure described below.

From time to time, our audit committee may pre-approve specified types of services that are expected to be provided to us by our independent registered public accounting firm during the next 12 months. Any such pre-approval details the particular service or type of services to be provided and is also generally subject to a maximum dollar amount.

Prior to the adoption of this policy, our Board of Directors pre-approved all audit and non-audit services to be performed by our independent registered public accounting firm.

22

During our 2022 and 2021 fiscal years, no services were provided to us by Ernst & Young LLP other than in accordance with the policies and procedures described above.

To approve Proposal No. 2, a majority of the votes properly cast must vote “FOR” this proposal.

The Board of Directors recommends voting “FOR” Proposal No. 2 to ratify the appointment of Ernst & Young LLP as SpringWorks’ independent registered public accounting firm for the fiscal year ending December 31, 2023.

23

PROPOSAL NO. 3 — NON-BINDING ADVISORY VOTE ON EXECUTIVE COMPENSATION

Our Board of Directors is committed to excellence in governance. The Dodd-Frank Wall Street Reform and Consumer Protection Act, and Section 14A(a)(1) of the Exchange Act, enables our stockholders, at least once every three years, to vote, on a non-binding advisory basis, on the compensation of our named executive officers, or a Say-on-Pay Vote, as disclosed in this proxy statement. In addition, we are required under the act to solicit our stockholders, at least once every six years, to vote, on a non-binding advisory basis, on the frequency of such Say-on-Pay Vote, or a say-on-frequency vote. At our fiscal 2021 annual meeting, our stockholders approved one year as the frequency for holding non-binding advisory votes to approve the compensation of our named executive officers. As part of that commitment and consistent with the results of the advisory “say-on-frequency” vote of our stockholders that was held at the fiscal 2021 annual meeting, our Board of Directors is providing the stockholders with an opportunity to partake, on a non-binding advisory basis, in a Say-on-Pay Vote. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the policies and practices described in this proxy statement. Our next non-binding, advisory say-on-frequency vote will be held before or during 2027.

As described below under “Executive Officer Compensation — Compensation Discussion and Analysis,” we have developed a compensation policy that is designed to attract and retain key executives responsible for our success and motivate management to enhance long-term stockholder value. We believe our compensation policy strikes an appropriate balance between the implementation of responsible, measured compensation practices and the effective provision of incentives for our named executive officers to exert their best efforts for our success.

For the reasons discussed above, the Board of Directors unanimously recommends that stockholders vote in favor of the following resolution at the annual meeting:

“RESOLVED, that the Company’s stockholders hereby approve, on a non-binding advisory basis, the compensation of the named executive officers, as disclosed in the Company’s proxy statement for the 2023 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the “Compensation Discussion and Analysis,” “Summary Compensation Table for Fiscal 2022” and the other compensation related tables and the narrative discussions that accompany such tables.”

To approve Proposal No. 3, a majority of the votes properly cast must vote “FOR” this proposal.

As this vote is advisory, it will not be binding upon our Board of Directors or compensation committee, and neither our Board nor our compensation committee will be required to take any action as a result of the outcome of this vote. However, our Board of Directors and our compensation committee value the opinions of our stockholders, and they will carefully consider the outcome of this vote when considering future executive compensation policies and decisions.

The Board of Directors recommends voting “FOR” the non-binding advisory resolution in Proposal No. 3 approving the compensation of the Company’s named executive officers.

Retirement of Michael Burgess

On September 16, 2022, Dr. Burgess retired from the Company. In connection with his retirement, Dr. Burgess and the Company entered into a Consulting and Separation Agreement, pursuant to which he was retained as a Senior Strategic Advisor to the Company in exchange for a fee-for-service consulting arrangement at an hourly rate of $300 and reimbursement of expenses related thereto. In addition, under the Consulting and Separation Agreement, the Company committed to provide Dr. Burgess with certain benefits related to his retirement including (a) twelve (12) months of base salary plus Dr. Burgess’ target annual incentive compensation for 2022 and (b) if Dr. Burgess was participating in the Company’s group health plan, a monthly cash payment for the shorter of twelve (12) months and Dr. Burgess’ COBRA continuation period.

Executive Summary

2022 Corporate Performance Highlights

During 2022, we achieved several important business milestones, including but not limited to, the following:

•

Advanced development of our late-stage rare oncology programs:

•

In May 2022, we announced positive topline results from the Phase 3 DeFi trial evaluating nirogacestat in patients with desmoid tumors, and we presented additional data from the DeFi trial at the European Society for Medical Oncology Congress in September 2022. In December 2022, we submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for the treatment of adults with desmoid tumors, which is being reviewed under the FDA’s Real-Time Oncology Review program. The NDA was accepted by the FDA in February 2023. The application has been granted Priority Review and given a Prescription Drug User Fee Act (PDUFA) action date of August 27, 2023.

25

•

In September 2022, we announced the initiation of a Phase 2 trial evaluating nirogacestat in patients with ovarian granulosa cell tumors.

•

In the fourth quarter of 2022, we participated in a Type C meeting with the FDA to align on the statistical analysis plan for the Phase 2b ReNeu trial evaluating mirdametinib in adult and pediatric patients with NF1-associated plexiform neurofibromas (NF1-PN) and expectations for an anticipated NDA submission in this indication. We expect to present topline data from the ReNeu trial in second half of 2023; and, assuming results are favorable, we plan to submit an NDA for mirdametinib as a treatment for NF1-PN in the first half of 2024.

•

Advanced development of our early-stage programs in multiple myeloma with our existing collaboration partners and biomarker-defined solid tumors:

•

In June 2022, initial clinical data from the Phase 1/2 study evaluating nirogacestat in combination with low-dose belantamab mafodotin, GSK plc’s (GSK) antibody drug conjugate targeting B-cell maturation antigen (BCMA), in patients with relapsed or refractory multiple myeloma were presented at the 2022 American Society of Clinical Oncology Annual Meeting. In September 2022, we entered into an expanded, global, non-exclusive license and collaboration agreement with GSK to evaluate nirogacestat in combination with belantamab mafodotin in patients with multiple myeloma, including in earlier lines of treatment.

•

In June 2022, we presented initial data that demonstrated clinical proof of concept for BGB-3245, a selective RAF dimer inhibitor being developed by MapKure, LLC, a joint venture between SpringWorks and BeiGene, as well as for the combination of mirdametinib and BeiGene’s RAF dimer inhibitor, lifirafenib. In addition, we advanced BGB-3245 monotherapy into dose expansion cohorts and announced plans for a new Phase 1/2a study evaluating BGB-3245 in combination with mirdametinib.

•

Advanced development of our preclinical programs and executed additional collaborations to expand our innovative pipeline:

•

In April 2022, we announced the execution of a clinical trial collaboration and supply agreement with Regeneron Pharmaceuticals to evaluate nirogacestat in combination with linvoseltamab (REGN5458), a BCMAxCD3 bispecific antibody, for the treatment of patients with relapsed or refractory multiple myeloma.

•

In the fourth quarter of 2022, we nominated a TEAD inhibitor development candidate, SW-682. We expect to present additional preclinical data of SW-682 at a medical conference in the first half of 2023 and to file an Investigational New Drug Application to the FDA for SW-682 in 2023.

•

Successful operational execution:

•

Throughout 2022, we strengthened our financial position with proceeds from several financing transactions, including $69.7 million in gross proceeds from an at-the-market offering, a $75 million equity investment from GSK and $225 million in gross proceeds from a private placement. We ended 2022 with cash, cash equivalents and marketable securities of $597.0 million.

•

We expanded and strengthened our intellectual property portfolio, including a new patent issued by the United States Patent and Trademark Office in November 2022 directed to pharmaceutical compositions of nirogacestat, which expires in 2042 and represents the seventh Orange Book-listable patent for nirogacestat.

•

We continued to build on our existing capabilities and established commercial infrastructure to support the anticipated first U.S. product launch of nirogacestat in desmoid tumors, growing our organization from 176 employees at the beginning of the year to 227 employees by the end of the year.

2022 Compensation Highlights

We believe that 2022 was a highly successful year for us due, in large part, to our achievement of significant clinical, research, business collaboration and other strategic milestones, as described above. With

26

respect to 2022 compensation decisions, our compensation committee and the Company’s Board of Directors, or Board, focused on ensuring that a significant portion of the total compensation awarded to our named executive officers was performance-based and linked to meeting our long-term strategic plan to create long-term stockholder value.

The substantial majority of our 2022 compensation to named executive officers was in the form of equity incentive awards. We believe that equity incentive awards further our long-term strategic plan to create long-term stockholder value. For 2022, our compensation committee granted annual equity awards to each of our named executive officers. In May 2022, to further incentivize their continued service through key 2022 research and development milestones, our compensation committee adopted a retention program for our senior research and development leaders, including Dr. Burgess and Dr. Smith. In addition, in light of the substantial decline in equity values of public companies in our industry, our compensation committee deemed it appropriate to provide one-time supplemental equity awards to our named executive officers, other than Mr. Burgess (who retired on September 16, 2022), in January 2023, with the exception of Mr. Ashar who received a one-time supplemental equity award in October 2022. A similar one-time equity grant was made to all of our non-executive employees in August 2022. The following charts illustrate the portion of compensation attributable to equity incentive awards, annual performance-based cash incentive awards and base salary for our Chief Executive Officer and for our other named executive officers, as a group.

Executive Compensation Philosophy and Overview

Our executive compensation program is intended to meet the following principal objectives:

•

attract, retain and motivate superior executive talent;

•

provide incentives that reward the achievement of performance goals that directly correlate to the enhancement of long-term stockholder value, as well as to facilitate executive retention;

•

differentiate compensation based on individual performance; and

•

align the executives’ interests with those of stockholders through long-term incentives linked to specific performance targets.

Based on this philosophy, our performance-driven compensation program primarily consists of three components: base salary, short-term cash incentive compensation, and long-term incentive compensation in the form of equity awards. Our compensation committee has determined that these three components, with a portion of target total direct compensation allocated to “at-risk” performance-based incentives through the use of short-term and long-term incentive compensation, best align the interests of our executive officers with those of our stockholders. While it does not have any formal policies for allocating compensation among the three components, our compensation committee reviews relevant competitive market data and uses its judgment to determine the appropriate level and mix of compensation on an annual basis to ensure that compensation levels and opportunities are competitive and that we are able to attract and retain capable executive officers to work for our long-term prosperity and stockholder value, without taking unnecessary or excessive risks.

Process for Setting Executive Compensation

We seek to foster a performance-oriented culture, where individual performance is aligned with organizational objectives. To achieve this, we evaluate and reward our executive officers based on their contributions to the achievement of annual goals and objectives set early in the year. Performance is reviewed at least annually through processes discussed further below, with a focus on our achievement of our corporate goals, and in view of economic and financial conditions affecting the performance period.

Consideration of “Say-on-Pay” Vote Advisory Vote

At our 2022 Annual Meeting of Shareholders, approximately 75% of the votes cast voted to approve the non-binding advisory resolution on our executive compensation. The compensation committee will continue to review the design of the executive compensation program, including in light of future say-on-pay vote outcomes, developments in executive compensation and the Company’s pay-for-performance philosophy and engage with stockholders to ensure that the executive compensation program continues to serve the best interests of the Company and its stockholders.

Role of the Compensation Committee

Our compensation committee reviews and approves our executive compensation philosophy, objectives and methods, evaluates our performance and the performance of our executive officers, and approves executive compensation, other than with respect to our Chief Executive Officer, and makes recommendations to our Board regarding our Chief Executive Officer’s compensation. The compensation committee also determines the Company’s achievement of its corporate goals, subject to a maximum level of 150%.

Please see “Corporate Governance — Board Committees — Compensation Committee” for additional information.

Awards of performance-based compensation for the previous year are typically made at the last-scheduled compensation committee meeting of the year. Adjustments to the base salaries of our named executive officers, if any, and reviews of annual equity awards are also typically made at the last-scheduled compensation committee meeting of the year.

Role of Management

For each year, annual Company goals are proposed by our senior management team and reviewed and approved by our Board of Directors and compensation committee. Our Chief Executive Officer’s cash incentive award is based entirely on performance relative to Company goals (to drive maximum stockholder value), and the cash incentive awards for our other named executive officers are based 80% on Company goals and 20% on individual objectives. Individual objectives for our senior management team other than our Chief Executive Officer are focused on leadership development objectives as well as individual contributions

28

that are intended to drive achievement of the Company goals and are proposed by each member of senior management, with review and input from the Chief Executive Officer. Any merit increases in base salary and any annual cash awards under our annual short-term incentive plan are based on the achievement of these Company goals and individual performance goals and objectives, as applicable.

During the last quarter of each year, our senior management team evaluates our company performance and each executive officer’s individual performance, as compared to the Company goals and, as applicable, the individual objectives for that year. Based on this evaluation, our Chief Executive Officer recommends to our compensation committee any increases in base salary and any annual equity awards and/or cash awards under our annual cash incentive program for members of the senior management team other than himself. Our compensation committee then meets in executive session (that is, without the presence of employee directors) to consider such recommendations and any recommendations made by the committee concerning our Chief Executive Officer’s own base salary or annual equity awards. Our Chief Executive Officer recuses himself from all discussions and recommendations regarding his own compensation.

Role of Compensation Consultant

Our compensation committee is authorized to engage a compensation consultant or other advisors to review our executive officers’ compensation, including an analysis against the compensation of executive officers at comparable companies, to ensure that our compensation is market competitive, with the goal of retaining and adequately motivating our senior management. During 2022, our compensation committee continued to engage Aon’s Human Capital Solutions practice, a division of Aon plc, or Aon, as its independent compensation consultant to make recommendations for updating our compensation peer group, and to review and make recommendations regarding our executive and director compensation. Aon was invited to attend a compensation committee meeting where they presented and discussed their analysis and findings. For 2022, with the assistance of Aon, our compensation committee updated our compensation peer group, described below in the section entitled “Peer Group and Market Compensation Data.” Aon’s fees for executive compensation consulting in fiscal year 2022 were approximately $104,240. The Company also uses affiliates of Aon for various services unrelated to executive or director compensation matters. Fees for such other services in fiscal year 2022 were approximately $415,130.

Before engaging Aon, our compensation committee analyzed whether Aon’s work as a compensation consultant would raise any conflict of interest, taking into consideration the following factors: (i) the provision of other services to our Company by Aon; (ii) the amount of fees received by Aon from us as a percentage of Aon’s total revenue; (iii) Aon’s own policies and procedures that are designed to prevent conflicts of interest; (iv) any business or personal relationship of Aon or the individual compensation advisors employed by the firm with a member of the compensation committee; and (v) any stock of our Company owned by the individual compensation advisors employed by Aon. Our compensation committee determined, based on its analysis of the above factors, that the work of Aon and the individual compensation advisors employed by Aon has not created any conflict of interest and our compensation committee is satisfied that Aon is independent pursuant to the listing standards of the relevant Nasdaq and SEC rules and has concluded that the engagement of Aon does not raise any conflict of interest.

Peer Group and Market Compensation Data

The compensation committee uses competitive compensation data from the annual total compensation study of peer companies to inform its decisions about overall compensation opportunities and specific compensation elements. The compensation committee also considers other reference points and criteria when establishing targeted compensation levels, such as the executive’s experience level, contribution to established Company’s goals, individual performance against the executive’s individual goals where applicable, scope of responsibility, skill sets, and leadership potential, as well as the Company’s critical needs and succession planning.

In evaluating the total compensation of our named executive officers, our compensation committee, using information provided by Aon, annually establishes a peer group of publicly traded companies in the biopharmaceutical and biotechnology industries that is selected based on a balance of the following criteria:

29

•

companies whose number of employees, stage of development and market capitalization are similar, though not necessarily identical, to ours;

•

companies with similar executive positions to ours;

•

companies against which we believe we compete for executive talent; and

•

public companies based in the United States whose compensation and financial data are available in proxy statements or through widely available compensation surveys.

Based on these criteria, our peer group for 2022, as approved by our compensation committee, consisted of the following 20 companies:

ACADIA Pharmaceuticals Inc.	Blueprint Medicines Corp.	Mirati Therapeutics, Inc.
Agios Pharmaceuticals, Inc.	BridgeBio Pharama, Inc.	Nektar Therapeutics
Allogene Therapeutics, Inc.	Deciphera Pharmaceuticals, Inc.	Revolution Medicines, Inc.
Apellis Pharmaceuticals, Inc.	Fate Therapeutics, Inc.	Sarepta Therapeutics, Inc.
Arcus Biosciences, Inc.	Global Blood Therapeutics. Inc.*	Turning Point Therapeutics, Inc.*
bluebird bio, Inc.	Iovance Biotherapeutics, Inc.	Ultragenyx Pharmaceutical, Inc.
Biohaven Pharmaceutical Holding Company Ltd.*	Legend Biotech Corp.	​

*

Denotes removal in 2022.

Based on a review of the analysis prepared by Aon, in October 2022, the compensation committee approved the updated compensation peer group below for determining compensation (i.e., base salary, short-term cash incentive compensation, and long-term incentive compensation in the form of equity awards) to be paid in 2023. The factors considered were similar for updating the peer group as set forth above, were reflective of the size and scope of the Company.

ACADIA Pharmaceuticals Inc.	bluebird bio, Inc.	Legend Biotech
Agios Pharmaceuticals, Inc.	Blueprint Medicines Corp.	Mirati Therapeutics, Inc.
Allogene Therapeutics, Inc.	BridgeBio Pharma, Inc.	Nektar Therapeutics

Executive Compensation Program and Compensation Decisions for the Named Executive Officers

The components of our executive compensation program in 2022 were as follows:

Annual Base Salary

The base salaries of our named executive officers are designed to compensate them for day-to-day services rendered during the fiscal year. Appropriate base salaries are used to recognize the experience, skills, knowledge and responsibilities required of each executive officer and to allow us to attract and retain individuals capable of leading us to achieve our business goals in competitive market conditions.

The base salaries of our named executive officers are reviewed at least annually, generally in the last quarter of each fiscal year, by our compensation committee and adjustments are made to reflect Company and individual performance, as well as competitive market practices. Our compensation committee also takes into account subjective performance criteria, such as an executive officer’s ability to lead, organize and motivate others, develop the skills necessary to mature with us, set realistic goals to be achieved in his or her

30

respective area, and recognize and pursue new business opportunities that enhance our growth and success. Our compensation committee does not apply specific formulas to determine increases, but instead makes an evaluation of each named executive officer’s contribution to our long-term success. Annual adjustments to base salaries are effective as of January 1 of each year, with mid-year adjustments to base salaries made under special circumstances, such as promotions or increased responsibilities. In December 2021, our compensation committee reviewed the annual base salaries of our named executive officers. After reviewing each executive’s performance against 2021 performance goals, taking into account a review of market data provided by Aon (including the impact to the market data due to changes in the composition of our peer group), the compensation committee recommended that the Board approve (and the Board subsequently approved) an increase to Mr. Islam’s 2021 annual base salary and approved increases to the 2021 annual base salaries of Mr. Perier, Mr. Ashar, Dr. Edris, Dr. Smith and Dr. Burgess each as set forth below and effective as of January 1, 2022.

The 2021 and 2022 base salaries for our named executive officers were as follows:

Name	2021 Base Salary ($)		2022 Base Salary ($)		Increase (%)
Saqib Islam, J.D.	​	590,000	​	680,000	​	15%
Francis I. Perier, Jr., M.B.A.	​	423,900	​	475,000	​	12%
Bhavesh Ashar, M.B.A.	​	450,000	​	475,000	​	6%
Badreddin Edris, Ph.D.	​	470,900	​	550,000	​	17%
L. Mary Smith, Ph.D.	​	440,200	​	460,000	​	4%
Michael Burgess, M.B.Ch.B., Ph.D*.	​	500,000	​	525,000	​	5%

*

Dr. Burgess retired from his employment with the Company on September 16, 2022.

In a series of meetings in late November and early December 2022, our compensation committee reviewed the annual base salary of Mr. Islam, Mr. Perier, Dr. Edris, Mr. Ashar and Dr. Smith. Following a review of each individual’s performance against the 2022 performance goals and after taking into account a review of market data provided by Aon (including the impact to the market data due to changes in the composition of our peer group) against the 2022 compensation of each individual executive, on December 7, 2022, the committee recommended the Board approve an increase in Mr. Islam’s annual base salary for 2023 from $680,000 to $720,000 and also approved the increase in Mr. Perier’s annual base salary for 2023 from $475,000 to $495,000, in Mr. Ashar’s annual base salary for 2023 from $475,000 to $500,000, in Dr. Smith’ annual base salary for 2023 from $460,000 to $500,000, and in Dr. Edris’s annual base salary for 2023 from $550,000 to $585,000. On December 12, 2022, the Board approved the increase to Mr. Islam’s annual base salary.

Short-Term Incentive Compensation

Our named executive officers are eligible to receive annual performance-based cash incentives, sometimes referred to as bonuses, as part of our annual short-term incentive plan, which are designed to provide appropriate short-term incentives to our executive officers to achieve pre-established annual corporate goals and to reward them for individual performance towards these goals. The annual bonus that each current named executive officer is eligible to receive under our annual short-term incentive plan is based on an individual bonus opportunity, which is a percentage of such named executive officer’s annual base salary established by our compensation committee, or in the case of Mr. Islam, by the Board, and is generally adjusted based on the extent to which we achieve the corporate goals that the Board establishes each year and (except for Mr. Islam whose performance under the annual short-term incentive plan is measured solely against our achievement of our annual corporate goals) such named executive officer’s individual performance. At the end of the year, the Board and compensation committee review our performance and approve the extent to which we achieved each of these corporate goals. Generally, the Board and compensation committee, as applicable, will assess each named executive officer’s individual contributions towards reaching our annual corporate goals and our Chief Executive Officer’s recommendations based on one-on-one assessments reviewing individualized performance achievements for our named executive officers (other than himself).

31

Our Board and compensation committee may grant above-target bonuses, for extraordinary performance against the pre-established goals, as well as taking into account other corporate and individual achievements.

The annual short-term incentive plan bonus opportunity targets as a percentage of 2022 base salaries for our named executive officers were as follows:

Name	2022 Target (%)		2022 Target ($)
Saqib Islam, J.D.	​	65%	​	$	442,000
Francis I. Perier, Jr., M.B.A.	​	40%	​	$	190,000
Bhavesh Ashar, M.B.A.	​	40%	​	$	190,000
Badreddin Edris, Ph.D.	​	50%	​	$	275,000
L. Mary Smith, Ph.D.	​	40%	​	$	184,000
Michael Burgess, M.B.Ch.B., Ph.D*	​	40%	​	$	210,000

*

While Dr. Burgess retired from his employment with the Company on September 16, 2022, pursuant to the terms of his consulting and separation agreement he is entitled to receive his target annual short-term incentive plan bonus following his retirement.

In a series of meetings in late November and early December 2022, and taking into account a review of market data for competitive target bonus opportunities for executives in our peer group that was provided to our compensation committee by Aon, our compensation committee recommended the Board approve an increase to Mr. Islam’s individual bonus opportunity from 65% of annual base salary to 70% of annual base salary for 2023. On December 12, 2022, the Board approved the increase to Mr. Islam’s individual bonus opportunity.

The corporate goals used in our annual short-term incentive plan were proposed by management and reviewed and approved by our compensation committee and our Board. The Board considered and assigned a percentage weighting to each of our corporate goals with an overall focus on enhancing stockholder value.

Our corporate goals for 2022 and the percentage weighting assigned to each goal are summarized as follows:

1.

Achieve topline readout of the DeFi trial, our registrational Phase 3 clinical trial of nirogacestat for adult patients with desmoid tumors, complete nirogacestat NDA filing and publish DeFi trial results in a prominent, peer-reviewed scientific journal (20%);

2.

Execute U.S. go-to-market strategy for nirogacestat in desmoid tumors, including organizational and compliance program readiness, building the field team for launch, and establishing a strategy for OUS development and commercialization (20%);

3.

Define regulatory approval path, and further develop medical and potential commercialization plans for mirdametinib in NF1-PN (10%);

4.

Support the release of initial data from at least two clinical collaborations involving nirogacestat and BCMA-targeted agents, execute additional agreement with GSK and support enrollment of new DREAMM-5 sub-studies, and provide further evidence of nirogacestat mechanism of action in multiple myeloma patients (10%);

5.

Advance clinical collaborations with BeiGene and MapKure to provide further clinical data from MEK and RAF inhibitor combinations and move to expansion cohorts (10%);

6.

Nominate development candidate for TEAD inhibitor program and advance preclinical/drug discovery infrastructure (5%);

7.

Raise sufficient capital to support commercial launch and corporate buildout through at least 2024 year-end (15%); and

32

8.

Execute organizational buildout with focus on total employee experience while maintaining high workforce diversity, below industry average turnover, and above industry average engagement (10%).

In a series of meetings in late November and early December 2022, our compensation committee and our Board reviewed our 2022 corporate goals, taking into account the weighting for each goal and its determination of an achievement rating with respect to each such goal, as well as additional organizational accomplishments in 2022, and approved payout of bonuses at the 130% level for the corporate component of the bonus. In addition, our compensation committee and our Board considered and accepted our Chief Executive Officer’s recommendations as to the achievement of individual goals by our named executive officers (other than himself).

In recognition of their efforts towards our successful achievement of such goals and milestones, our compensation committee approved awarding Mr. Perier, Mr. Ashar and Dr. Edris their respective individual bonuses for 2022 at approximately 130% of each executive’s individual bonus opportunity, taking into account the Board’s determination that the Company achieved its corporate goals at the 130% level with respect to 80% of the bonus calculation, with the remaining 20% of such calculation based on the named executive officer’s individual performance in accordance with the recommendations of our Chief Executive Officer, and recommended, and the Board approved, awarding Mr. Islam approximately 130% of his individual bonus opportunity for 2022. The 2022 annual bonus payments, which were paid in February 2023, are summarized in the table below.

Name	2022 Annual Bonus ($)		% of 2022 Base Salary
Saqib Islam, J.D.	​	574,600	​	85%
Francis I. Perier, Jr., M.B.A.	​	235,600	​	50%
Bhavesh Ashar, M.B.A.	​	247,000	​	52%
Badreddin Edris, Ph.D.	​	368,500	​	67%
L. Mary Smith, Ph.D.	​	242,880	​	53%
Michael Burgess, M.B.Ch.B., Ph.D*.	​	210,000	​	40%

*

While Dr. Burgess retired from his employment with the Company on September 16, 2022, pursuant to the terms of his consulting and separation agreement he is entitled to receive his 2022 target annual short-term incentive plan bonus following his retirement.

Long-Term Incentive Compensation

We provide long-term incentive compensation to our named executive officers through the grant of equity awards. We believe that equity awards create incentives for our named executive officers to further our long-term strategic plan to create long-term stockholder value. We also believe equity awards create an ownership culture. In addition, the vesting requirements of our equity awards contributes to executive retention by providing an incentive to our named executive officers to remain employed by us during the vesting period.

Generally, significant equity awards are granted at the time a named executive officer commences employment. Thereafter, equity awards may be granted at varying times and in varying amounts in the discretion of our compensation committee or, if awards are being granted to the Chief Executive Officer, in the discretion of the Board, but are generally made once a year unless such named executive officer is promoted, or for recognition of outstanding performance. None of our named executive officers is currently party to an employment agreement that provides for an automatic grant of stock options or other equity awards.

Like many other companies in our compensation peer group, we include both restricted stock unit grants and stock option grants in our executive compensation program to attract and retain highly qualified executives. In this regard, while both stock options and restricted stock units enable our named executive officers to benefit, like stockholders, from any increases in the value of our common stock, stock options deliver future value only if the value of our common stock increases above the exercise price. In contrast,

33

restricted stock units deliver fully paid shares of our stock upon vesting, so, during periods of stock market volatility, restricted stock units help retain employees. In addition, full value awards, such as restricted stock units, are less dilutive to existing stockholders since fewer shares are needed to achieve an equivalent value relative to stock options.

The exercise price of our stock options is equal to the fair market value (the closing market price on the Nasdaq Global Select Market) of our common stock on the date of grant. Our stock options have a ten-year term and generally vest over a four-year period on a monthly basis (i.e., 1/48th each month) until such award is fully vested, except that our stock options for new hires vest over a four-year period, with 25% vesting on the first anniversary of the grant and the balance vesting in equal monthly installments over the next three years until such award is fully vested, subject in each case to vesting acceleration as described under the heading “— Potential Payments Upon Termination or Change of Control” below. The restricted stock units which were granted to our named executive officers in 2022 vest in three equal annual installments from the grant date, subject to vesting acceleration as described under the heading “— Potential Payments Upon Termination or Change of Control” below. The other terms of the equity awards are governed by our 2019 Stock Option and Equity Incentive Plan, as amended.

The vesting schedule and the number of shares granted are established to ensure a meaningful incentive to remain in our employ. Accordingly, the stock award will provide a return to the employee only if he or she remains in our service, and, in the case of the stock option component, only if the market price of our common stock appreciates over the option term.

In determining the 2022 annual equity awards to our named executive officers, our compensation committee considered the equity awards granted within the 50th to 75th percentile range to the executives holding comparable positions at our peer group companies, as well as each named executive officer’s existing equity holdings, level of responsibility and criticality, unvested status of existing equity holdings, in addition to the committee’s subjective assessment of each named executive officer’s individual performance and our overall company performance.

The equity awards granted to our named executive officers during 2022 were as follows:

Name	Options to Purchase Shares of Our Common Stock (#)		Restricted Stock Units (#)		Grant Date Fair Value ($)
Saqib Islam, J.D.	​	244,258	​	78,370	​	14,033,647
Francis I. Perier, Jr., M.B.A.	​	58,622	​	18,809	​	3,368,090
Bhavesh Ashar, M.B.A.	​	140,710(1)	​	13,062	​	4,213,384
Badreddin Edris, Ph.D.	​	81,420	​	26,124	​	4,677,948
L. Mary Smith, Ph.D.	​	69,207	​	28,297(2)	​	4,126,216
Michael Burgess, M.B.Ch.B., Ph.D(3)	​	48,852	​	27,859(2)	​	3,106,740

(1)

For 2022, in addition to annual equity awards, our compensation committee granted a supplemental award to Mr. Ashar, as a retention measure to secure employment and to incentivize long-term commitment and performance.

(2)

For 2022, in addition to annual equity awards, our compensation committee granted additional equity awards, in the form of fully vested stock awards, as a retention measure to each Dr. Burgess and Dr. Smith to secure their respective employment and to incentivize their respective long-term commitment and performance, described under the heading “— Other Equity Awards Made in 2022/Special One Time Retention Awards” below.

(3)

Dr. Burgess retired from his employment with the Company on September 16, 2022. All unvested equity awards were forfeited immediately upon termination of employment.

Other Equity Awards Made in 2022/Special One Time Retention Awards

In May 2022, to further incentivize their continued service through key 2022 research and development milestones, our compensation committee adopted a retention program, which included both a fully vested

34

stock award and a grant of restricted stock units, or RSUs, for certain of our senior research and development leaders, including Drs. Burgess and Smith. In addition, in light of the substantial decline in equity values of public companies in our industry, our compensation committee deemed it appropriate to provide one-time supplemental equity awards to our named executive officers, other than Dr. Burgess (who retired on September 16, 2022), in January 2023, with the exception of Mr. Ashar who received a one-time supplemental equity award in October 2022. Our compensation committee authorized a similar one-time equity grant to all of our non-executive employees in August 2022.

On January 5, 2023, our chief executive officer, or CEO, was granted a supplemental equity award consisting of a performance-based RSU. The RSU covers a target of 284,362 shares and vests over a four-year performance period subject to the achievement of certain milestones. In addition, the target number of shares covered is subject to modification (upwards or downwards) by up to 25% based upon the relative total shareholder return of our shares compared to the NASDAQ Biotech Index as of the end of the performance period.

Grants made in connection with the retention program and one-time supplementary equity awards are summarized in the table below.

Health and Welfare Benefits

All of our full-time employees, including our named executive officers, are eligible to participate in certain medical, disability and life insurance benefit programs offered by us. We pay the premiums for term life insurance and long-term disability for all of our employees, including our named executive officers. We also provide all employees, including named executive officers, with a flexible spending account plan, and paid time-off benefits including vacation, sick time and holidays. We do not sponsor any qualified or non-qualified defined benefit plans for any of our employees or executives.

Section 401(k) Plan

We maintain a tax-qualified retirement plan, or the 401(k) Plan, that provides eligible U.S. employees with an opportunity to save for retirement on a tax advantaged basis. Eligible employees are able to defer eligible compensation subject to applicable annual limits provided for in the Internal Revenue Code, or the Code. We make 50% matching contributions into the 401(k) plan on behalf of participants, for up to the

35

first 5% of eligible compensation. Employees’ pre-tax or Roth contributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participants’ directions. Employees are immediately and fully vested in their contributions. Our 401(k) Plan is intended to be qualified under Section 401(a) of the Code with our 401(k) Plan’s related trust intended to be tax exempt under Section 501(a) of the Code. As a tax-qualified retirement plan, contributions to our 401(k) Plan and earnings on those contributions are not taxable to the employees until distributed from our 401(k) Plan.

Perquisites

We pay a portion of the premiums for medical, dental, group term life, disability and accidental death and dismemberment insurance for all of our full-time employees. We generally do not provide excessive perquisites or personal benefits to our named executive officers. Our named executive officers participate in a health evaluation plan and receive reimbursement for medical concierge services for our named executive officers, giving each individual access to efficient, high-quality healthcare options, while allowing each of them to be more effective in the performance of their individual duties, and for recruitment and retention purposes. All practices with respect to perquisites or other personal benefits must be approved, and are subject to periodic review, by our compensation committee. Our Board may elect to adopt qualified or nonqualified benefit plans in the future if it determines that doing so is in our best interests.

Post-Employment Compensation

Our named executive officers are entitled to certain severance and change of control payments and benefits pursuant to their respective employment agreement with us, as described in more detail below in the section titled “— Potential Payments Upon Termination or Change of Control.” Each such employment agreement provides for a combination of a lump-sum cash severance payment, continued health benefits, and acceleration of vesting on outstanding equity awards in specified circumstances. Acceleration of vesting is subject to a “double trigger” arrangement, meaning that vesting acceleration occurs only in the event of a change of control of the Company in connection with or followed by a termination of employment without cause by us, or with good reason by the named executive officer. Each such employment agreement also provides the named executive officer certain specified compensation in the event of such named executive officer’s death or permanent disability.

Given the industry in which we participate and the range of strategic initiatives that we may explore, we believe these arrangements are an essential element of our executive compensation package and assist us in recruiting and retaining talented individuals. In addition, since we believe it may be difficult for our executive officers to find comparable employment following an involuntary termination of employment in connection with or following a change of control of the Company, these payments and benefits are intended to ease the consequences to an executive officer of an unexpected termination of employment. By establishing these payments and benefits, we believe we can mitigate the distraction and loss of executive officers that may occur in connection with rumored or actual fundamental corporate changes and thereby protect stockholder interests while a transaction is under consideration or pending.

Accounting and Tax Considerations

Under Financial Accounting Standard Board ASC Topic 718, or ASC Topic 718, we are required to estimate and record an expense for each share-based payment award (including stock options) over the vesting period of the award. We record share-based compensation expense on an ongoing basis according to ASC Topic 718. Our compensation committee has considered, and may in the future consider, the grant of performance-based or other types of stock awards to our executive officers in lieu of or in addition to stock options in light of the accounting impact of ASC Topic 718 and other considerations.

Compensation paid to each of the Company’s “covered employees” in excess of $1 million per taxable year generally will not be deductible unless it qualifies for the reliance period exception under Section 162(m). Because of certain ambiguities and uncertainties as to the application and interpretation of Section 162(m), as well as other factors beyond the control of the compensation committee, no assurance can be given that any compensation paid by the Company will qualify for the reliance period exception under Section 162(m) and be deductible by the Company in the future. Although the compensation committee

36

will continue to consider tax implications as one factor in determining executive compensation, the compensation committee also looks at other factors in making its decisions and retains the flexibility to provide compensation for the Company’s named executive officers in a manner consistent with the goals of the Company’s executive compensation program and the best interests of the Company and its stockholders, which may include providing for compensation that is not deductible by the Company due to the deduction limit under Section 162(m). The compensation committee also retains the flexibility to modify compensation that was initially intended to be exempt from the deduction limit under Section 162(m) if it determines that such modifications are consistent with the Company’s business needs.

Includes the Company’s 2019 Stock Option and Equity Incentive Plan, or the 2019 Plan, and 2019 Employee Stock Purchase Plan.

(2)

The 2019 Plan provides that the number of shares reserved and available for issuance under the 2019 Plan will automatically increase each January 1, beginning on January 1, 2020, by 5% of the outstanding number of shares of our common stock on the immediately preceding December 31 or such lesser number of shares as determined by our compensation committee. This number will be subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization. The shares of common stock underlying any awards that are forfeited, cancelled, held back upon exercise or settlement of an award to satisfy the exercise price or tax withholding, reacquired by us prior to vesting, satisfied without the issuance of stock, expire or are otherwise terminated, other than by exercise, under the 2019 Plan and the 2019 Plan will be added back to the shares of common stock available for issuance under the 2019 Plan. The Company no longer issues grants under the 2019 Plan. As of December 31, 2022, a total of 1,852,890 shares of our common stock have been reserved for issuance pursuant to the 2019 Employee Stock Purchase Plan. The 2019 Employee Stock Purchase Plan provides that the number of shares reserved and available for issuance under the plan will automatically increase each January 1, beginning on January 1, 2020, by the lesser of 663,229 shares of our common stock, 1% of the outstanding number of shares of our common stock on the immediately preceding December 31 or such lesser number of shares as determined by the compensation committee. This number will be subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization.

The Peer Group TSR set forth in this table utilizes the Nasdaq Biotechnology Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report on Form 10-K for the year ended December 31, 2022. The comparison assumes $100 was invested for the period starting December 31, 2019, through the end of the listed year in the Company and in the Nasdaq Biotechnology Index, respectively. Historical stock performance is not necessarily indicative of future stock performance.

We determined Net Cash Provided By Financing Activities to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs in 2022. As described in the Compensation Discussion and Analysis, one of the goals associated with our 2022 performance-based cash incentive was to raise sufficient capital to support commercial launch and corporate buildout through at least 2024 year-end, and such metric was determined by reference to Net Cash Provided By Financing Activities. This performance measure may not have been the most important financial performance measure for years 2021 and 2020 and we may determine a different financial performance measure to be the most important financial performance measure in future years.

The following chart compares our cumulative TSR over the three most recently completed fiscal years to that of the Nasdaq Biotechnology Index over the same period.

Tabular List of Most Important Financial Performance Measures

Net Cash Provided by Financing Activities was the sole financial performance measure that the Company used in linking Compensation Actually Paid to our PEO and other NEOs for 2022 to Company performance.

CEO Pay Ratio

Pursuant to SEC rules, we are required to provide information regarding the relationship between the annual total compensation of our CEO, and the median annual total compensation of our employees (other than our CEO) for the year ended December 31, 2022.

Measurement Date

We identified the median employee using our employee population on December 31, 2022 (including all employees, whether employed on a full-time, part-time, seasonal or temporary basis).

Consistently Applied Compensation Measure

Under the SEC rules, we are required to identify the median employee by use of a “consistently applied compensation measure”, or CACM. We chose a CACM that closely approximates the annual target total direct compensation of our employees. Specifically, we identified the median employee by aggregating for each employee as of December 31, 2022: (1) annual base pay, (2) annual target cash incentive opportunity, (3) the fair market value for equity awards granted during the fiscal year ended December 31, 2022 (as determined at the grant date), and (4) any other items of compensation earned by, or paid to, such employee during 2022. For employees who joined the Company during 2022, we annualized their compensation values for base pay and annual performance-based cash incentive where applicable.

Methodology and Pay Ratio

After applying our CACM methodology, we identified the median employee. Once the median employee was identified, we calculated the median employee’s annual total direct compensation in accordance with the requirements of the Summary Compensation Table.

53

Our median employee compensation in 2022 as calculated using Summary Compensation Table requirements was $433,241. Our Chief Executive Officer’s compensation in 2022, as reported in the Summary Compensation Table, was $15,295,291. Therefore, our CEO Pay Ratio for 2022 is approximately 35:1.

We believe this ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K under the Exchange Act. This information is being provided for compliance purposes, based on our internal records and the methodology described above. The SEC rules for identifying the median compensated employee allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. Accordingly, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may use different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios. Neither our compensation committee nor management of the Company used the CEO Pay Ratio measure in making compensation decisions.

Risk Assessment Concerning Compensation Practices and Policies

We believe that although a portion of the compensation provided to our executive officers and other employees is performance-based, our executive compensation program does not encourage excessive or unnecessary risk taking. This is primarily due to the fact that our compensation programs are designed to encourage our executive officers and other employees to remain focused on both short-term and long-term strategic goals. As a result, we do not believe that our compensation programs are reasonably likely to have a material adverse effect on us.

Compensation Committee Interlocks and Insider Participation

During 2022, Carlos Albán, Daniel S. Lynch and Jeffrey Schwartz served on our compensation committee. Messrs. Lynch and Schwartz have served as members of our compensation committee since our initial public offering in September 2019 and continue to serve on such committee at present. Mr. Lynch previously served as our executive chairman from August 2017 to August 2019 and as our interim Chief Executive Officer from February 2018 to July 2018. Mr. Schwartz is affiliated with one of our large stockholders, BC SW, LP, as set forth in this proxy statement. See “Certain Relationships and Related Party Transactions” for further discussion.

DELINQUENT SECTION 16(A) REPORTS

Section 16(a) of the Exchange Act requires our directors and executive officers, and persons who beneficially own more than ten percent of a registered class of our equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock and other equity securities. Officers, directors and greater than ten percent beneficial owners are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file.

To our knowledge, based solely on our review of Forms 3, 4 and 5, and any amendments thereto, furnished to us or written representations that no Form 5 was required, we believe that during the fiscal year ended December 31, 2022, all filing requirements applicable to our executive officers and directors under the Exchange Act were met in a timely manner except for one Form 4 for Bhavesh Ashar filed on October 13, 2022, which reported a transaction on April 1, 2022, and one Form 4/A for each of Michael Nofi, Daniel Pichl, Herschel Weinstein, Francis I. Perier, Jr., and L. Mary. Smith that were filed on January 11, 2022, which reported withholding transactions from January 7, 2022.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Certain Relationships and Transactions

Other than the compensation agreements and other arrangements described under “Executive Officer Compensation” and “Director Compensation” in this proxy statement and the transactions described below, since January 1, 2022, there has not been and there is not currently proposed, any transaction or series of similar transactions to which we were, or will be, a party in which the amount involved exceeded, or will exceed, $120,000 (or, if less, 1% of the average of our total assets amounts at December 31, 2021 and 2022) and in which any director, executive officer, holder of 5% or more of any class of our capital stock or any member of the immediate family of, or entities affiliated with, any of the foregoing persons, had, or will have, a direct or indirect material interest.

Sale of Securities

On September 7, 2022, we entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with certain investors, including Boxer Capital, LLC, entities affiliated with EcoR1 Capital, LLC, entities affiliated with FMR LLC and Perceptive Life Sciences Master Fund, Ltd., for aggregate gross proceeds of $225 million, before deducting fees to the placement agent, the structuring agent and other offering expenses payable by the Company. Pursuant to the terms of the Securities Purchase Agreement, the Company issued and sold to the investors in a private placement an aggregate of 8,650,520 shares of the Company’s common stock, par value $0.0001 per share, at a purchase price of $26.01 per share.

Employment agreement with Daniel S. Lynch

On February 1, 2018, we entered into an Employment Agreement with Daniel S. Lynch, or the Lynch Agreement, pursuant to which (i) Mr. Lynch served as the Executive Chairman of our Board of Directors and (ii) from February 1, 2018 until July 31, 2018, Mr. Lynch served as our interim Chief Executive Officer, in each case on an at-will basis. On August 16, 2019, we entered into a letter agreement, or the Termination Letter, with Mr. Lynch, pursuant to which the parties agreed that the Lynch Agreement would terminate effective immediately. Following such termination, Mr. Lynch no longer serves as Executive Chairman, and serves as the Chairman of our Board of Directors.

The Termination Letter provides that all of the rights and obligations of the parties accrued as of the date thereof will survive the termination of the Lynch Agreement. In addition, the Termination Letter provides for the treatment of outstanding stock options and restricted stock awards held by Mr. Lynch as of the date of the Termination Letter. Pursuant to the Termination Letter, upon a Sale of the Company (as defined in the Termination Letter), all equity awards held by Mr. Lynch as of the date of the Termination Letter shall be accelerated in full.

Investors’ Rights Agreement

We are a party to an investors’ rights agreement, dated as of March 29, 2019, with holders of our preferred stock (which such stock converted to common stock upon the consummation of our initial public offering), including holders of 5% or more of our capital stock and entities affiliated with our directors. The investor rights agreement provides these holders the right to demand that we file a registration statement or request that their shares be covered by a registration statement that we are otherwise filing. The investor rights agreement also provided a right of first refusal to purchase future securities sold by us, which such right terminated immediately prior to the consummation of our initial public offering.

We amended our investors’ rights agreement on February 25, 2021, whereby the aforementioned right to demand that we file a registration statement or request that such investors’ shares be covered by a registration statement that we are otherwise filing shall terminate for any holder of our common stock whose common stock may be sold pursuant to Rule 144 under the Securities Act of 1933, as amended.

Limitation of Liability and Indemnification of Officers and Directors

Our certificate of incorporation contains provisions that limit the liability of our directors for monetary damages to the fullest extent permitted by Delaware law. Consequently, our directors will not be personally

57

liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors, except liability for the following:

•

any breach of their duty of loyalty to our company or our stockholders;

•

any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

•

unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law; or

•

any transaction from which they derived an improper personal benefit.

Any amendment to, or repeal of, these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to that amendment or repeal. If the Delaware General Corporation Law is amended to provide for further limitations on the personal liability of directors of corporations, then the personal liability of our directors will be further limited to the greatest extent permitted by the Delaware General Corporation Law.

In addition, we adopted bylaws which provide that we will indemnify, to the fullest extent permitted by law, any person who is or was a party or is threatened to be made a party to any action, suit or proceeding by reason of the fact that he or she is or was one of our directors or officers or is or was serving at our request as a director or officer of another corporation, partnership, joint venture, trust, or other enterprise. Our bylaws provide that we may indemnify to the fullest extent permitted by law any person who is or was a party or is threatened to be made a party to any action, suit, or proceeding by reason of the fact that he or she is or was one of our employees or agents or is or was serving at our request as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise. Our bylaws also provide that we must advance expenses incurred by or on behalf of a director or officer in advance of the final disposition of any action or proceeding, subject to very limited exceptions.

We have entered into, and in the future plan to enter into, agreements to indemnify our directors and executive officers. These agreements, among other things, require us to indemnify these individuals for certain expenses (including attorneys’ fees), judgments, fines and settlement amounts reasonably incurred by such person in any action or proceeding, including any action by or in our right, on account of any services undertaken by such person on behalf of our company or that person’s status as a member of our Board of Directors to the maximum extent allowed under Delaware law.

Related Person Transaction Policy

Our Board of Directors has adopted a written related person transactions policy providing that transactions with our directors, officers and holders of 5% or more of our voting securities and their affiliates, each a related person, must be approved by our audit committee. This policy became effective on September 12, 2019, the date our registration statement for our initial public offering became effective. Pursuant to this policy, the audit committee has the primary responsibility for reviewing and approving or disapproving “related person transactions,” which are transactions between us and related persons in which a related person has or will have a direct or indirect material interest and in which the aggregate amount involved exceeds or may be expected to exceed $120,000 annually, subject to certain exceptions. For purposes of this policy, a related person is defined as a director, executive officer, nominee for director, or greater than 5% beneficial owner of our common stock, in each case since the beginning of the most recently completed year, and their immediate family members.

As appropriate for the circumstances, the audit committee will review and consider:

•

the related person’s interest in the related person transaction;

•

the approximate dollar amount involved in the related person transaction;

•

the approximate dollar amount of the related person’s interest in the transaction without regard to the amount of any profit or loss;

•

whether the transaction was undertaken in the ordinary course of our business;

58

•

whether the terms of the transaction are no less favorable to us than terms that could have been reached with an unrelated third party;

•

the purpose of, and the potential benefits to us of, the related-party transaction; and

•

any other information regarding the related-party transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.

59

Shares of our common stock issuable upon the exercise of options or pursuant to restricted stock units that are subject to vesting conditions within 60 days of March 30, 2023 are considered outstanding and beneficially owned by the person holding the options or restricted stock units for the purpose of calculating the percentage ownership of that person but not for the purpose of calculating the percentage ownership of any other person. Except as otherwise noted, the persons and entities in this table have sole voting and investing power with respect to all of the shares of our common stock beneficially owned by them, subject to community property laws, where applicable.

REPORT OF THE AUDIT COMMITTEE

The audit committee is appointed by the Board of Directors to assist the Board of Directors in fulfilling its oversight responsibilities with respect to:

•

the integrity of SpringWorks Therapeutics’ financial statements and financial reporting process and systems of internal controls regarding finance, accounting, and compliance with legal and regulatory requirements;

•

the qualifications, independence, and performance of SpringWorks Therapeutics’ independent registered public accounting firm;

•

the performance of SpringWorks Therapeutics’ internal audit function, if any; and

•

other matters as set forth in the charter of the audit committee approved by the Board of Directors.

The audit committee reviews the Company’s financial disclosures and meets privately, outside the presence of management, with the independent registered public accounting firm. The audit committee also reviews the performance of the independent registered public accounting firm in the annual audit of SpringWorks’ financial statements and in assignments unrelated to the audit, and reviews the independent registered public accounting firm’s fees. The audit committee provides the Board of Directors such information and materials as it may deem necessary to apprise the Board of Directors of financial matters requiring its attention. In addition, the audit committee reviews and reassesses our charter annually and recommends any changes to the Board of Directors for approval.

Management is responsible for the preparation of SpringWorks Therapeutics’ financial statements and the financial reporting process, including its system of internal control over financial reporting and its disclosure controls and procedures. The independent registered public accounting firm is responsible for performing an audit of SpringWorks Therapeutics’ financial statements in accordance with the standards of the Public Company Accounting Oversight Board, or the PCAOB, and issuing a report thereon. The audit committee’s responsibility is to monitor and oversee these processes.

In connection with these responsibilities, the audit committee reviewed and discussed with management and the independent registered public accounting firm the audited consolidated financial statements of SpringWorks Therapeutics for the fiscal year ended December 31, 2022. The audit committee also discussed with the independent registered public accounting firm the matters required to be discussed by the PCAOB’s Auditing Standard No. 1301, Communication with Audit Committees. In addition, the audit committee received written communications from the independent registered public accounting firm confirming its independence as required by the applicable requirements of the PCAOB and has discussed with the independent registered public accounting firm its independence.

Based on the reviews and discussions referred to above, the audit committee recommended to the Board of Directors that the audited consolidated financial statements of SpringWorks Therapeutics be included in SpringWorks Therapeutics’ Annual Report on Form 10-K for the fiscal year ended December 31, 2022, that was filed with the Securities and Exchange Commission, or the SEC. The information contained in this report shall not be deemed to be (i) “soliciting material,” ​(ii) “filed” with the SEC, (iii) subject to Regulations 14A or 14C of the Exchange Act, or (iv) subject to the liabilities of Section 18 of the Exchange Act. This report shall not be deemed incorporated by reference into any of our other filings under the Exchange Act or the Securities Act of 1933, as amended, except to the extent that we specifically incorporate it by reference into such filing.

HOUSEHOLDING

Some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that only one copy of our documents, including the annual report to stockholders and proxy statement, may have been sent to multiple stockholders in your household. We will promptly deliver a separate copy of either document to you upon written or oral request to SpringWorks Therapeutics, Inc., 100 Washington Blvd, Stamford, Connecticut 06902, Attention: Corporate Secretary. If you want to receive separate copies of the proxy statement or annual report to stockholders in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your bank, broker or other nominee record holder, or you may contact us at the above address and phone number.

STOCKHOLDER PROPOSALS

A stockholder who would like to have a proposal considered for inclusion in our 2024 proxy statement must submit the proposal in accordance with the procedures outlined in Rule 14a-8 of the Exchange Act so that it is received by us no later than December 9, 2023, which is 120 days before the first anniversary of the date on which the Company’s proxy materials for the 2023 Annual Meeting were first made available to stockholders. Any stockholder proposals submitted outside the processes of SEC Rule 14a-8 will be considered untimely. However, if the date of the 2024 Annual Meeting of Stockholders is changed by more than 30 days from the date of the previous year’s meeting, then the deadline is a reasonable time before we begin to print and send our proxy statement for the 2024 Annual Meeting of Stockholders. If that happens, we will publicly announce the deadline for submitting a proposal in a press release or in a document filed with the SEC. SEC rules set standards for eligibility and specify the types of stockholder proposals that may be excluded from a proxy statement.

If a stockholder wishes to propose a nomination of persons for election to our Board of Directors or present a proposal at an annual meeting but does not wish to have the proposal considered for inclusion in our proxy statement and proxy card, our bylaws establish an advance notice procedure for such nominations and proposals. Stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the Board of Directors or by a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has delivered timely notice in proper form to our Corporate Secretary of the stockholder’s intention to bring such business before the meeting.

The required notice must be in writing and received by our Corporate Secretary at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary of the preceding year’s annual meeting. However, in the event that the date of the annual meeting is advanced by more than 30 days, or delayed by more than 60 days, from the first anniversary of the preceding year’s annual meeting, a stockholder’s notice must be so received no earlier than the 120th day prior to such annual meeting and not later than the close of business on the later of (i) the 90th day prior to such annual meeting and (ii) the tenth day following the day on which notice of the date of such annual meeting was mailed or public disclosure of the date of such annual meeting was made, whichever first occurs. For stockholder proposals to be brought before the 2024 Annual Meeting of Stockholders, the required notice must be received by our Corporate Secretary at our principal executive offices no earlier than January 25, 2024 and no later than February 24, 2024.

In addition, any stockholder proposal intended to be included in the proxy statement for the next annual meeting of our stockholders in 2024 must also satisfy the requirements of SEC Rule 14a-8 under the Exchange Act and be received no later than December 9, 2023, which is 120 days before the first anniversary of the date on which the Company’s proxy materials for the Annual Meeting were first made available to stockholders. Any stockholder proposals submitted outside the processes of SEC Rule 14a-8, or received after December 9, 2023, will be considered untimely. In addition, to comply with the SEC’s new universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than our nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 25, 2024. If the date of the annual meeting is moved by more than 30 days from the date contemplated at the time of the previous year’s proxy statement, then notice must be received within a

64

reasonable time before we begin to print and send proxy materials. If that happens, we will publicly announce the deadline for submitting a proposal in a press release or in a document filed with the SEC.

Stockholder proposals and the required notice should be addressed to SpringWorks Therapeutics, Inc., 100 Washington Blvd, Stamford, Connecticut 06902, Attention: Corporate Secretary.

OTHER MATTERS

Our Board of Directors does not know of any other matters to be brought before the Annual Meeting. If any other matters not mentioned in this proxy statement are properly brought before the meeting, the individuals named in the enclosed proxy intend to use their discretionary voting authority under the proxy to vote the proxy in accordance with their best judgment on those matters.
