As part of our effort to maintain a safe and healthy environment for our directors, members of management and stockholders who wish to attend the Annual Meeting, in light of the novel coronavirus disease, COVID-19, we believe that hosting a virtual meeting this year is in the best interest of the company and its stockholders and a virtual meeting enables increased stockholder attendance and participation because stockholders can participate from any location around the world.

The Securities and Exchange Commission rules allow companies to furnish proxy materials to stockholders over the Internet. We have elected to do so, thus reducing the environmental impact and lowering the costs of printing and distributing proxy materials without impacting your timely access to this important information.

The Notice of Internet Availability also provides instructions on how to vote and includes instructions on how to receive paper copies of the proxy materials by mail, or an electronic copy of the proxy materials by email, if desired.

The matters to be acted upon at the meeting are described in the accompanying notice of Annual Meeting and proxy statement.

Your vote is important.

Whether or not you plan to attend the virtual Annual Meeting, please vote on the Internet or by telephone, or request, sign and return a proxy card to ensure that your shares are represented at the meeting.

PROXY STATEMENT FOR THE 2021 ANNUAL MEETING OF STOCKHOLDERS

June 8, 2021

INFORMATION ABOUT SOLICITATION AND VOTING

The accompanying proxy is solicited on behalf of the Board of Directors of Stoke Therapeutics, Inc., (Stoke or the Company), for use at the Company’s 2021 Annual Meeting of Stockholders, or Annual Meeting on Tuesday, June 8, 2021 at 9:00 a.m. (Eastern Time), and any adjournment or postponement thereof. Due to the COVID-19 pandemic and related public health concerns, the Annual Meeting will be held virtually at www.virtualshareholdermeeting.com/STOK2021. It is important that you retain a copy of the 16-digit control number found on the proxy card, voting instruction form or Notice, as such number will be required in order for stockholders to participate in the virtual Annual Meeting.

INTERNET AVAILABILITY OF PROXY MATERIALS

Under rules adopted by the Securities and Exchange Commission (SEC), we are furnishing proxy materials to our stockholders primarily via the Internet, instead of mailing printed copies to each stockholder. On or about April 26, 2021, we expect to send to our stockholders a Notice of Internet Availability of Proxy Materials (Notice of Internet Availability) containing instructions on how to access our proxy materials, including our proxy statement and our Annual Report on Form 10-K. The Notice of Internet Availability also provides instructions on how to vote and includes instructions on how to receive paper copies of the proxy materials by mail, or an electronic copy of the proxy materials by email.

This process is designed to reduce our environmental impact and lower the costs of printing and distributing our proxy materials while providing our stockholders timely access to this important information. If you would prefer to receive printed proxy materials, please follow the instructions included in the Notice of Internet Availability.

GENERAL INFORMATION ABOUT THE MEETING

Purpose of the Meeting

At the meeting, stockholders will act upon the proposals described in this proxy statement. In addition, we will consider any other matters that are properly presented for a vote at the meeting. We are not aware of any other matters to be submitted for consideration at the meeting. If any other matters are properly presented for a vote at the meeting, the persons named in the proxy, who are officers of the company, have the authority in their discretion to vote the shares represented by the proxy.

Record Date; Quorum

Only holders of record of common stock at the close of business on April 12, 2021, the record date, will be entitled to vote at the meeting. At the close of business on April 12, 2021, 36,703,171 shares of common stock were outstanding and entitled to vote. For ten days prior to the meeting, a complete list of the stockholders entitled to vote at the meeting will be available for examination upon request by any stockholder for any purpose relating to the meeting by written request via email to our Corporate Secretary at corporatesecretary@stoketherapeutics.com. A list of stockholders entitled to vote at the Annual Meeting will also be available for examination on the Internet through the virtual web conference during the Annual Meeting.

The holders of a majority of the voting power of the shares of stock entitled to vote at the meeting as of the record date must be present or represented by proxy at the meeting in order to hold the meeting and conduct business. This presence is called a quorum. Your shares are counted as present at the meeting if you are present and vote in person at the meeting or if you have properly submitted a proxy.

GENERAL PROXY INFORMATION

Voting Rights; Required Vote

Each holder of shares of common stock is entitled to one vote for each share of common stock held as of the close of business on April 12, 2021, the record date. You may vote all shares owned by you at such date, including (1) shares held directly in your name as the stockholder of record and (2) shares held for you as the beneficial owner in street name through a broker, bank, trustee or other nominee. Dissenters’ rights are not applicable to any of the matters being voted on.

Stockholder of Record: Shares Registered in Your Name. If on April 12, 2021, your shares were registered directly in your name with our transfer agent, American Stock Transfer & Trust Company, LLC, then you are considered the stockholder of record with respect to those shares. As a stockholder of record, you may vote at the meeting, or vote in advance through the Internet or by telephone, or if you request to receive paper proxy materials by mail, by filling out and returning the proxy card.

Beneficial Owner: Shares Registered in the Name of a Broker or Nominee. If on April 12, 2021, your shares were held in an account with a brokerage firm, bank or other nominee, then you are the beneficial owner of the shares held in street name. As a beneficial owner, you have the right to direct your broker on how to vote the shares held in your account, and your broker has enclosed or provided voting instructions for you to use in directing it on how to vote your shares. Because the brokerage firm, bank or other nominee that holds your shares is the stockholder of record, if you wish to attend the meeting and vote your shares, you must obtain a valid proxy from the firm that holds your shares giving you the right to vote the shares at the meeting.

We strongly recommend that you vote your shares in advance of the Annual Meeting as instructed above, even if you plan to attend the Annual Meeting virtually.

Each director will be elected by a plurality of the votes cast at the meeting. This means that the two individuals nominated for election to the Board of Directors at the meeting receiving the highest number of “FOR” votes will be elected. You may vote “FOR ALL NOMINEES”, or vote to “WITHHOLD AUTHORITY FOR ALL NOMINEES” or vote “FOR ALL EXCEPT” one or more of the nominees you specify. Shares represented by proxies will be voted “FOR” the election of the Class II nominees, unless the proxy is marked to withhold authority to so vote. You may not cumulate votes in the election of directors. Approval of the ratification of the appointment of our independent registered public accounting firm will be obtained if the holders of a majority of the votes cast at the meeting vote “FOR” the proposal.

A proxy submitted by a stockholder may indicate that the shares represented by the proxy are not being voted (stockholder withholding) with respect to a particular matter. In addition, a broker may not be permitted to vote on shares held in street name on a particular matter in the absence of instructions from the beneficial owner of the stock (broker non-vote). The shares subject to a proxy which are not being voted on a particular matter because of either stockholder withholding or broker non-votes will count for purposes of determining the presence of a quorum but are not treated as votes cast and, therefore, will have no effect on the election of directors or the ratification of the appointment of KPMG LLP. Abstentions are voted neither “for” nor “against” a matter and, therefore, will have no effect on the election of directors or the ratification of the appointment of KPMG LLP but are counted in the determination of a quorum.

Recommendations of the Board of Directors on Each of the Proposals Scheduled to be Voted on at the Meeting

The Board of Directors recommends that you vote FOR the election of Arthur A. Levin and Jennifer C. Burstein to serve as Class II directors until the 2024 annual meeting of stockholders or until his or her successor has been duly elected and qualified (Proposal 1) and FOR the ratification of the appointment of KPMG LLP as our

independent registered public accounting firm for the fiscal year ending December 31, 2021 (Proposal 2). None of the directors or executive officers has any substantial interest in any matter to be acted upon, other than elections to office with respect to the director nominated in Proposal 1.

Voting Instructions; Voting of Proxies

If you are a stockholder of record, you may:

•

vote via the virtual meeting website—any stockholder can attend the Annual Meeting by visiting www.virtualshareholdermeeting.com/STOK2021, where stockholders may vote and submit questions during the meeting. The meeting starts at 9:00 a.m. Eastern Time. Please have your 16-Digit Control Number to join the Annual Meeting. Instructions on how to attend and participate via the Internet are posted at www.proxyvote.com

•

vote through the Internet or by telephone—in order to do so, please follow the instructions shown on your proxy card; or

•

vote by mail—if you request or receive a paper proxy card and voting instructions by mail, simply complete, sign and date the proxy card and return it as soon as possible before the meeting in the envelope provided.

Votes submitted through the Internet or by telephone must be received by 11:59 p.m., Eastern Time, on June 7, 2021. Submitting your proxy, whether by telephone, through the Internet or by mail if you requested or received a paper proxy card, will not affect your right to vote via the Internet should you decide to attend the virtual Annual Meeting. If you are not the stockholder of record, please refer to the voting instructions provided by your nominee to direct how to vote your shares. For Proposal 1, you may vote “FOR ALL NOMINEES”, “WITHHOLD AUTHORITY FOR ALL NOMINEES” or vote “FOR ALL EXCEPT” one or more of the nominees you specify. For Proposal 2, you may vote “FOR” or “AGAINST” or “ABSTAIN” from voting. Your vote is important. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure that your vote is counted.

All proxies will be voted in accordance with the instructions specified on the proxy card. If you sign a physical proxy card and return it without instructions as to how your shares should be voted on a particular proposal at the meeting, your shares will be voted in accordance with the recommendations of our Board of Directors stated above.

If you received a Notice of Internet Availability, please follow the instructions included on the notice on how to access and vote your proxy card. If you do not vote and you hold your shares in street name, and your broker does not have discretionary power to vote your shares, your shares may constitute “broker non-votes” (as described above) and will not be counted in determining the number of shares necessary for approval of the proposals. However, shares that constitute broker non-votes will be counted for the purpose of establishing a quorum for the meeting.

If you receive more than one proxy card or Notice of Internet Availability, your shares are registered in more than one name or are registered in different accounts. To make certain all of your shares are voted, please follow the instructions included on the Notice of Internet Availability on how to access and vote each proxy card. If you requested or received paper proxy materials by mail, please complete, sign, date and return each proxy card to ensure that all of your shares are voted.

Expenses of Soliciting Proxies

We will pay the expenses associated with soliciting proxies. Following the original distribution and mailing of the solicitation materials, we or our agents may solicit proxies by mail, email, telephone, facsimile, by other

similar means, or in person. Our directors, officers and other employees, without additional compensation, may solicit proxies personally or in writing, by telephone, email or otherwise. Following the original distribution and mailing of the solicitation materials, we will request brokers, custodians, nominees and other record holders to forward copies of those materials to persons for whom they hold shares and to request authority for the exercise of proxies. In such cases, we, upon the request of the record holders, will reimburse such holders for their reasonable expenses. If you choose to access the proxy materials and/or vote through the Internet, you are responsible for any Internet access charges you may incur.

Revocability of Proxies

A stockholder of record who has given a proxy may revoke it at any time before the closing of the polls by the inspector of elections at the meeting by:

•

delivering to our Corporate Secretary (by any means, including facsimile) a written notice stating that the proxy is revoked;

•

signing and delivering a proxy bearing a later date;

•

voting again through the Internet or by telephone; or

•

attending virtually and voting during the meeting (although attendance at the meeting will not, by itself, revoke a proxy).

Please note, however, that if your shares are held of record by a brokerage firm, bank or other nominee, and you wish to revoke a proxy, you must contact that firm to revoke or change any prior voting instructions.

Electronic Access to the Proxy Materials

The Notice of Internet Availability will provide you with instructions regarding how to:

•

view our proxy materials for the meeting through the Internet;

•

instruct us to mail paper copies of our future proxy materials to you; and

•

instruct us to send our future proxy materials to you electronically by email.

Choosing to receive your future proxy materials by email will reduce the impact of our annual meetings of stockholders on the environment and lower the costs of printing and distributing our proxy materials. If you choose to receive future proxy materials by email, you will receive an email next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials by email will remain in effect until you terminate it.

Voting Results

Voting results will be tabulated and certified by the inspector of elections appointed for the meeting. The final results will be tallied by the inspector of elections and filed with the SEC in a Current Report on Form 8-K within four business days of the meeting.

Participating in the Annual Meeting

To participate in the virtual meeting, visit www.virtualshareholdermeeting.com/STOK2021 and enter the 16-digit control number included on your proxy card or on the instructions that accompanied your proxy materials.

If you wish to submit a question during the Annual Meeting, log into the virtual meeting platform at www.virtualshareholdermeeting.com/STOK2021, type your question into the “Ask a Question” field, and click

“Submit.” If your question is properly submitted during the relevant portion of the meeting agenda, we will respond to your question during the live webcast. A webcast replay of the Annual Meeting, including the Q&A session, will also be archived on the “Investor Relations” section of our website, which is located at https://investor.stoketherapeutics.com.

If we experience technical difficulties during the meeting (e.g., a temporary or prolonged power outage), we will determine whether the meeting can be promptly reconvened (if the technical difficulty is temporary) or whether the meeting will need to be reconvened on a later day (if the technical difficulty is more prolonged). In any situation, we will promptly notify shareholders of the decision via www.virtualshareholdermeeting.com/STOK2021. If you encounter technical difficulties accessing our meeting or asking questions during the meeting, a support line will be available on the login page of the virtual meeting website.

Implications of Being an “Emerging Growth Company”

We are an “emerging growth company” as that term is used in the Jumpstart Our Business Startups Act of 2012 and, as such, have elected to comply with certain reduced public company reporting requirements. These reduced reporting requirements include reduced disclosure about the company’s executive compensation arrangements and no requirement to have non-binding advisory votes on executive compensation. We will remain an emerging growth company until the earliest of (1) December 31, 2024; (2) the last day of the fiscal year (a) in which we have total annual gross revenue of at least $1.07 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the prior June 30th; and (3) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

CORPORATE GOVERNANCE STANDARDS AND DIRECTOR INDEPENDENCE

We are committed to good corporate governance practices. These practices provide an important framework within which our Board of Directors and management pursue our strategic objectives for the benefit of our stockholders.

Corporate Governance Guidelines

Our Board of Directors has adopted Corporate Governance Guidelines that set forth expectations for directors, director independence standards, Board committee structure and functions, and other policies for the governance of the company. Our Corporate Governance Guidelines are available without charge on the investor relations section of our website at https://investor.stoketherapeutics.com/governance.

Board Composition and Leadership Structure

The positions of Chief Executive Officer and Chairman of our Board of Directors are held by two different individuals (Edward M. Kaye and Seth L. Harrison, respectively). This structure allows our Chief Executive Officer to focus on our day-to-day business while our Chairman leads our Board of Directors in its fundamental role of providing advice to and independent oversight of management. Our Board of Directors believes such separation is appropriate, as it enhances the accountability of the Chief Executive Officer to the Board of Directors and strengthens the independence of the Board of Directors from management.

Board’s Role in Risk Oversight

Our Board of Directors believes that open communication between management and the Board of Directors is essential for effective risk management and oversight. Our Board of Directors meets with our Chief Executive Officer and other members of the senior management team at quarterly Board of Director meetings, where, among other topics, they discuss strategy and risks in the context of reports from the management team and evaluate the risks inherent in significant transactions. While our Board of Directors is ultimately responsible for risk oversight, our Board committees assist the Board of Directors in fulfilling its oversight responsibilities in certain areas of risk. The Audit Committee assists our Board of Directors in fulfilling its oversight responsibilities with respect to risk management in the areas of internal control over financial reporting and disclosure controls and procedures. The Compensation Committee assists our Board of Directors in assessing risks created by the incentives inherent in our compensation policies. The Nominating and Corporate Governance Committee assists our Board of Directors in fulfilling its oversight responsibilities with respect to the management of corporate, legal and regulatory risk.

Director Independence

Our common stock is listed on the Nasdaq Global Select Market. Under the rules of the Nasdaq Stock Market, independent directors must constitute a majority of a listed company’s Board of Directors. In addition, the rules of the Nasdaq Stock Market require that, subject to specified exceptions, each member of a listed company’s Audit, Compensation and Nominating and Corporate Governance Committees must be an “independent director”. Under the rules of the Nasdaq Stock Market, a director will only qualify as an “independent director” if, in the opinion of that 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. Additionally, Compensation Committee members must not have a relationship with the listed company that is material to the director’s ability to be independent from management in connection with the duties of a Compensation Committee member. Audit Committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended (Exchange Act). 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: (i) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or (ii) be an affiliated person of the listed company or any of its subsidiaries.

Our Board of Directors has undertaken a review of the independence of each director and director nominee and considered whether each director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. As a result of this review, our Board of Directors determined that Jennifer C. Burstein, Seth L. Harrison, Arthur A. Levin, Adrian R. Krainer, Garry E. Menzel, Julie Anne Smith and Arthur O. Tzianabos, representing seven of our eight directors following the meeting, are “independent directors” as defined under the applicable rules and regulations of the SEC and the listing requirements and rules of the Nasdaq Stock Market. In making these determinations, our Board of Directors reviewed and discussed information provided by the directors and us with regard to each directors’ business and personal activities and relationships as they may relate to us and our management, including the beneficial ownership of our capital stock by each non-employee director and any affiliates.

Committees of Our Board of Directors

Our Board of Directors has established an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee, each of which has the composition and responsibilities described below. Members serve on these committees until their resignation or until otherwise determined by our Board of Directors. Each of these committees has a written charter, copies of which are available without charge on the investor relations section of our website at https://investor.stoketherapeutics.com/governance.

Audit Committee

Our Audit Committee comprises Arthur O. Tzianabos, Arthur A. Levin and Jennifer C. Burstein. Ms. Burstein is the Chair of our Audit Committee. The composition of our Audit Committee meets the requirements for independence under the current Nasdaq Stock Market and SEC rules and regulations. Each member of our Audit Committee is financially literate. In addition, our Board of Directors has determined that Ms. Burstein is an “audit committee financial expert” as defined in Item 407(d)(5)(ii) of Regulation S-K promulgated under the Securities Act. Our Audit Committee is directly responsible for, among other things:

•

selecting and hiring our independent registered public accounting firm;

•

the qualifications, independence and performance of our independent auditors;

•

the preparation of the audit committee report to be included in our annual proxy statement;

•

our compliance with legal and regulatory requirements;

•

our accounting and financial reporting processes, including our financial statement audits and the integrity of our financial statements; and

•

reviewing and approving related-person transactions.

Compensation Committee

Our Compensation Committee comprises of Seth L. Harrison, Julie Anne Smith, Garry E. Menzel and Arthur O. Tzianabos. Dr. Tzianabos is the Chair of our Compensation Committee. The composition of our Compensation Committee meets the requirements for independence under the current Nasdaq Stock Market and SEC rules and regulations. Our Compensation Committee is responsible for, among other things:

•

evaluating, recommending, approving and reviewing executive officer compensation arrangements, plans, policies and programs;

•

evaluating and recommending non-employee director compensation arrangements for determination by our Board of Directors;

•

administering our cash-based and equity-based compensation plans; and

•

overseeing our compliance with regulatory requirements associated with the compensation of directors, officers and employees.

The Compensation Committee has the sole authority and responsibility, subject to any approval by the Board of Directors which the Compensation Committee or legal counsel determines to be desirable or required by applicable law or the Nasdaq rules, to determine all aspects of executive compensation packages for the Chief Executive Officer and other executive officers. The Compensation Committee also makes recommendations to our Board of Directors regarding the form and amount of compensation of non-employee directors. The Compensation Committee may take into account the recommendations of the Chief Executive Officer with respect to compensation of the other executive officers, and the recommendations of the Board of Directors or any member of the Board of Directors with respect to compensation of the Chief Executive Officer and other executive officers.

The Compensation Committee engaged an independent executive compensation consulting firm, Radford, a part of Aon plc, (Radford), or Radford, to evaluate our executive compensation program and practices and to provide advice and ongoing assistance on executive compensation matters for the fiscal year ended December 31, 2020. Specifically, Radford was engaged to:

•

provide compensation-related data for a peer group of companies to serve as a basis for assessing competitive compensation practices;

•

review and assess our current director, Chief Executive Officer and other executive officer compensation policies and practices and equity profile, relative to market practices;

•

review and assess our current executive compensation program relative to market to identify any potential changes or enhancements to be brought to the attention of the Compensation Committee; and

•

review market practices regarding equity programs.

Representatives of Radford met informally with the Chair of the Compensation Committee and attended the regular meetings of the Compensation Committee, including executive sessions from time to time without any members of management present. During the fiscal year ended December 31, 2020, Radford worked directly with the Compensation Committee (and not on behalf of management) to assist the committee in satisfying its responsibilities and undertook no projects for management without the committee’s prior approval. The Compensation Committee has determined that none of the work performed by Radford during the fiscal year ended December 31, 2020 raised any conflict of interest.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee comprises Seth L. Harrison, Arthur A. Levin and Adrian R. Krainer. Dr. Harrison is the Chair of our Nominating and Corporate Governance Committee. Our Nominating and Corporate Governance Committee is responsible for, among other things:

•

identifying, considering and recommending candidates for membership on our Board of Directors;

•

overseeing the process of evaluating the performance of our Board of Directors; and

•

advising our Board of Directors on other corporate governance matters.

Codes of Conduct and Ethics

Our Board of Directors has adopted a code of business conduct and ethics that applies to all of our employees, officers and directors, including our Chief Executive Officer, Chief Financial Officer and other executive and senior financial officers. We intend to disclose future amendments to certain provisions of our code of conduct, or waivers of these provisions, on our website or in public filings. The full text of our code of conduct is posted on the investor relations section of our website at https://investor.stoketherapeutics.com/governance.

Board and Committee Meetings and Attendance

The Board of Directors and its committees meet regularly throughout the year and also hold special meetings and act by written consent from time to time. During 2020, the Board of Directors held four meetings including

telephonic meetings; the Audit Committee held five meetings; the Compensation Committee held five meetings and the Nominating and Corporate Governance Committee held four meetings. During 2020, none of the directors attended fewer than 75% of the aggregate of the total number of meetings held by the Board of Directors during his or her tenure and the total number of meetings held by all committees of the Board of Directors on which such director served during his or her tenure. The independent members of the Board of Directors also meet separately without management directors on a regular basis to discuss such matters as the independent directors consider appropriate.

Board Attendance at Annual Stockholders’ Meeting

We invite and encourage each member of our Board of Directors to attend our annual meetings of stockholders. We do not have a formal policy regarding attendance of our annual meetings of stockholders by the members of our Board of Directors.

Communication with Directors

Stockholders and interested parties who wish to communicate with our Board of Directors, non-management members of our Board of Directors as a group, a committee of the Board of Directors or a specific member of our Board of Directors (including our Chairman) may do so by letters addressed to:

Stoke Therapeutics, Inc.

c/o Corporate Secretary

45 Wiggins Avenue

Bedford, MA 01730

All communications by letter addressed to the attention of our Corporate Secretary will be reviewed by the Corporate Secretary and provided to the members of the Board of Directors unless such communications are unsolicited items, sales materials and other routine items and items unrelated to the duties and responsibilities of the Board of Directors.

Considerations in Evaluating Director Nominees

The Nominating and Corporate Governance Committee is responsible for identifying, considering and recommending candidates to the Board of Directors for Board membership. A variety of methods are used to identify and evaluate director nominees, with the goal of maintaining and further developing a diverse, experienced and highly qualified Board of Directors. Candidates may come to our attention through current members of our Board of Directors, professional search firms, stockholders or other persons.

The Nominating and Corporate Governance Committee will recommend to the Board of Directors for selection all nominees to be proposed by the Board of Directors for election by the stockholders, including approval or recommendation of a slate of director nominees to be proposed by the Board of Directors for election at each annual meeting of stockholders, and will recommend all director nominees to be appointed by the Board of Directors to fill interim director vacancies. Our Board of Directors encourages selection of directors who will contribute to the company’s overall corporate goals. The Nominating and Corporate Governance Committee may from time to time review and recommend to the Board of Directors the desired qualifications, expertise and characteristics of directors, including such factors as business experience, diversity and personal skills in life sciences and biotechnology, finance, marketing, financial reporting and other areas that are expected to contribute to an effective Board of Directors. Exceptional candidates who do not meet all of these criteria may still be considered. In evaluating potential candidates for the Board of Directors, the Nominating and Corporate Governance Committee considers these factors in the light of the specific needs of the Board of Directors at that time.

In addition, under our Corporate Governance Guidelines, a director is expected to spend the time and effort necessary to properly discharge such director’s responsibilities. Accordingly, a director is expected to regularly

attend meetings of the Board of Directors and committees on which such director sits, and to review prior to meetings material distributed in advance for such meetings. Thus, the number of other public company boards and other boards (or comparable governing bodies) on which a prospective nominee is a member, as well as his or her other professional responsibilities, will be considered. Also under our Corporate Governance Guidelines, there are no limits on the number of three-year terms that may be served by a director. However, in connection with evaluating recommendations for nomination for reelection, the Nominating and Corporate Governance Committee considers director tenure. We value diversity on a company-wide basis but have not adopted a specific policy regarding Board diversity.

Stockholder Recommendations for Nominations to the Board of Directors

The Nominating and Corporate Governance Committee will consider properly submitted stockholder recommendations for candidates for our Board of Directors who meet the minimum qualifications as described above. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a stockholder. A stockholder of record can nominate a candidate for election to the Board of Directors by complying with the procedures in Article I, Section 1.12 of our bylaws. Any eligible stockholder who wishes to submit a nomination should review the requirements in the bylaws on nominations by stockholders. Any nomination should be sent in writing to our Corporate Secretary, Stoke Therapeutics, Inc., 45 Wiggins Avenue, Bedford, MA 01730. Submissions must include the full name of the proposed nominee, complete biographical information, a description of the proposed nominee’s qualifications as a director, other information specified in our bylaws, and a representation that the nominating stockholder is a beneficial or record holder of our stock. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected. These candidates are evaluated at meetings of the Nominating and Corporate Governance Committee, and may be considered at any point during the year. If any materials are provided by a stockholder in connection with the recommendation of a director candidate, such materials are forwarded to the Nominating and Corporate Governance Committee.

Additional information regarding the process for properly submitting stockholder nominations for candidates for membership on our Board of Directors is set forth below under “Stockholder Proposals to Be Presented at Next Annual Meeting.”

PROPOSAL NO. 1

ELECTION OF CLASS II DIRECTORS

Our Board of Directors is divided into three classes. Each class serves for three years, with the terms of office of the respective classes expiring in successive years. Directors and director nominees in Class II will stand for election at this meeting. The terms of office of directors in Class I and Class III do not expire until the annual meetings of stockholders to be held in 2023 and 2022, respectively. Our Nominating and Corporate Governance Committee recommended to our Board of Directors, and our Board of Directors nominated Arthur A. Levin and Jennifer C. Burstein, each an incumbent Class II director, for election as Class II directors at the Annual Meeting. At the recommendation of our Nominating and Corporate Governance Committee, our Board of Directors proposes that the Class II nominees be elected as Class II directors for a three-year term expiring at the annual meeting of stockholders to be held in 2024 and until such directors’ successors are duly elected and qualified or until such directors’ earlier resignation or removal.

The directors will be elected by a plurality of the votes present in person or represented by proxy at the Annual Meeting and entitled to vote on the election of directors. This means that the two individuals nominated for election to the Board of Directors at the Annual Meeting receiving the highest number of “FOR” votes will be elected. You may vote “FOR ALL NOMINEES” or vote to “WITHHOLD AUTHORITY FOR ALL NOMINEES” or vote “FOR ALL EXCEPT” one or more of the nominees you specify. Shares represented by proxies will be voted “FOR” the election of the Class II nominee unless the proxy is marked to withhold authority to so vote. You may not cumulate votes in the election of directors. If any nominee for any reason is unable to serve, the proxies may be voted for such substitute nominee as the proxy holders, who are officers of our company, might determine. The nominees have consented to being named in this proxy statement and to serve if elected. Proxies may not be voted for more than two directors.

Non-Employee Director Compensation

For the year ended December 31, 2020, our non-employee directors received the following compensation:

•

Cash Compensation. Our non-employee director compensation program provided an annual cash retainer of $35,000 to each non-employee director. Additionally, the Chairman of our Board of Directors receives an additional annual payment of $30,000; the Chairmen of our Audit, Compensation and Nominating and Corporate Governance Committees received an additional annual payment of $15,000, $10,000 and $8,000 respectively; and the members of our Audit, Compensation and Nominating and Corporate Governance Committees received an additional annual payment of $7,500, $5,000 and $4,000 respectively.

Equity Compensation. Each new non-employee director who joined our Board of Directors was automatically granted an option to purchase 29,555 shares of our common stock (or such other number of shares of our common stock as may have been determined by our board of directors from time to time, subject to the limits set forth in the 2019 Equity Incentive Plan) upon the director’s initial appointment to our board of directors. Such grants vest in twelve substantially equal quarterly installments on each quarterly anniversary of the date of grant (or such other vesting schedule as may have been determined by our board of directors from time to time, subject to the limits set forth in the 2019 Equity Incentive Plan), such that the grant will become fully vested and exercisable on the three-year anniversary of the date of grant, subject to the director’s continued service on each applicable vesting date. On the date of each annual meeting of stockholders, each non-employee director who continued to serve on our Board of Directors immediately following such meeting received an option to purchase 14,777 shares of our common stock (or such other number of shares of our common stock as may be determined by our board of directors from time to time, subject to the limits set forth in the 2019 Equity Incentive Plan), which grant will vest on the one-year anniversary of the date of the grant, such that the grant will become fully vested and exercisable on the one-year anniversary of the date of grant, or if earlier, the next annual meeting of our stockholders, subject to the director’s continued service on each applicable vesting date.

Non-employee directors are also reimbursed for reasonable expenses incurred in serving as a director, including travel expenses for attending meetings of our Board of Directors.

After December 31, 2020, our compensation committee revised the compensation to be paid to our non-employee directors incrementally, to increase the annual cash retainer from $30,000 to $40,000 for each non-employee director, and to reduce the equity compensation from 29,555 shares of our common stock and 14,777 shares of our common stock, to 23,300 shares of our common stock and 11,650 shares of our common stock, for new non-employee director appointments and annual grants for continuing directors, respectively, in light of the appreciation in value of our common stock.

Our Chief Executive Officer, Dr. Kaye, receives no compensation for his service as a director. Other than as described below, none of our non-employee directors

received any fees or reimbursement of any expenses (other than customary expenses in connection with the attendance of meetings of our Board of Directors) or any equity or non-equity awards in the year ended December 31, 2020.

At the Annual Meeting, the stockholders are being asked to ratify the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021. Our Audit Committee is submitting the selection of KPMG LLP to our stockholders because we value our stockholders’ views on our independent registered public accounting firm and as a matter of good corporate governance. If this proposal does not receive the affirmative approval of a majority of the votes cast on the proposal, the Audit Committee would reconsider the appointment. Notwithstanding its selection and even if our stockholders ratify the selection, our Audit Committee, in its discretion, may appoint another independent registered public accounting firm at any time during the year if the Audit Committee believes that such a change would be in our best interests and the interests of our stockholders.

The following table presents fees for professional audit services rendered by KPMG LLP for the audit of our annual financial statements for the years ended December 31, 2020 and 2019 (in thousands).

Our Audit Committee may also pre-approve particular services on a case-by-case basis. All of the services relating to the fees described in the table above were approved by our Audit Committee.

Percentage ownership of our common stock is based on 36,697,808 shares of our common stock outstanding on March 31, 2021.

CERTAIN RELATIONSHIPS AND RELATED-PARTY TRANSACTIONS

In addition to the compensation arrangements, including employment, termination of employment and change in control arrangements, with our directors and executive officers, including those discussed in the sections entitled “Management” and “Executive Compensation,” the following is a description of each transaction since January 1, 2020 and each currently proposed transaction in which:

•

we have been or are to be a participant;

•

the amounts involved exceeded or will exceed the lesser of $120,000 and 1% of our total assets; and

•

any of our directors, executive officers or holders of more than 5% of our capital stock, or an affiliate or immediate family member of the foregoing persons, had or will have a direct or indirect material interest.

Other than as described below, there have not been, nor are there any currently proposed, transactions or series of similar transactions to which we have been or will be a party other than compensation arrangements, which are described where required under the section entitled “Executive Compensation.”

Policies and Procedures for Related Party Transactions

Our Board has adopted a written Related-Party Transactions Policy that provides that our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of our common stock, and any members of the immediate family of and any entity affiliated with any of the foregoing persons, are not permitted to enter into a material related person transaction with us without the review and approval of our Audit Committee, or a committee composed solely of independent directors in the event it is inappropriate for our audit committee to review such transaction due to a conflict of interest. The policy provides that any request for us to enter into a transaction with an executive officer, director, nominee for election as a director, beneficial owner of more than 5% of our common stock or with any of their immediate family members or affiliates in which the amount involved exceeds $120,000 will be presented to our Audit Committee (or the committee composed solely of independent directors, if applicable) for review, consideration and approval. In approving or rejecting any such proposal, we expect that our audit committee (or the committee composed solely of independent directors, if applicable) will consider the relevant facts and circumstances available and deemed relevant to the Audit Committee (or the committee composed solely of independent directors, if applicable), including, but not limited to, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction.

ADDITIONAL INFORMATION

Delinquent Section 16(a) Reports

Section 16(a) of the Securities Exchange Act of 1934 requires our executive officers and directors, and persons who own more than 10% of a registered class of our equity securities, to file reports of ownership on Forms 3, 4 and 5 with the SEC. Executive officers, directors and greater than 10% stockholders are required to furnish us with copies of all Forms 3, 4 and 5 they file. Based solely on our review of the copies of such forms we have received and written representations from certain reporting persons that they filed all required reports, we believe that all of our executive officers, directors and greater than 10% stockholders complied on a timely basis with all Section 16(a) filing requirements applicable to them with respect to transactions during 2020, except for a Form 4 for Gene Liau filed on March 4, 2021 covering one transaction on December 28, 2020, a Form 3 for Garry Menzel filed on January 27, 2021 due on August 13, 2020, and a Form 4 for Garry Menzel filed on January 27, 2021 covering one transaction on August 13, 2020.

Stockholder Proposals to be Presented at Next Annual Meeting

Requirements for Stockholder Proposals to be Brought Before an Annual Meeting. Our bylaws provide that for stockholder nominations to our Board of Directors or other proposals to be considered at an annual meeting of stockholders, the stockholder must give timely notice thereof in writing to the Corporate Secretary at Stoke Therapeutics, Inc., 45 Wiggins Avenue, Bedford, MA 01730.

To be timely for our company’s annual meeting of stockholders to be held in 2022 (2022 Annual Meeting), a stockholder’s notice must be delivered to or mailed and received by our Corporate Secretary at our principal executive offices not earlier than the close of business on February 8, 2022 and not later than the close of business on March 10, 2022. A stockholder’s notice to the Corporate Secretary must set forth as to each matter the stockholder proposes to bring before the 2022 Annual Meeting the information required by applicable law and our bylaws. However, if the date of the 2022 Annual Meeting is more than 30 days before or more than 60 days after the one-year anniversary of the date of our 2020 Annual Meeting, for the stockholder notice to be timely, it must be delivered to the Corporate Secretary at our principal executive offices (1) not earlier than the close of business on the 120th day prior to the currently proposed annual meeting and (2) not later than the close of business on the later of the 90th day prior to such annual meeting or the close of business on the 10th day following the day on which public announcement of the date of such meeting is first made by us.

Available Information

We will mail without charge, upon written request, a copy of our Annual Report on Form 10-K for the year ended December 31, 2020, including the financial statements and list of exhibits, and any exhibit specifically requested. Requests should be sent to:

Stoke Therapeutics, Inc.

45 Wiggins Avenue

Bedford, MA 01730

Attn: Investor Relations

The Annual Report on Form 10-K is also available at https://investor.stoketherapeutics.com/financials-and-sec-filings.

“Householding”—Stockholders Sharing the Same Address

The SEC has adopted rules that permit companies and intermediaries (such as brokers) to implement a delivery procedure called “householding.” Under this procedure, multiple stockholders who reside at the same address may receive a single copy of our Annual Report on Form 10-K and proxy materials, including the Notice of Internet Availability, unless the affected stockholder has provided other instructions. This procedure reduces printing costs and postage fees and helps protect the environment as well.

We expect that a number of brokers with account holders who are our stockholders will be “householding” our Annual Report on Form 10-K and proxy materials, including the Notice of Internet Availability. A single Notice of Internet Availability and, if applicable, a single set of Annual Report on Form 10-K and other proxy materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from one or more of the affected stockholders. Once you have received notice from your broker that it will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. Stockholders may revoke their consent at any time by contacting their broker. Stockholders may revoke their consent at any time by contacting American Stock Transfer & Trust Company, LLC, through their website at www.astfinancial.com or by phone at (800) 937-5449.

Upon written or oral request, we will undertake to promptly deliver a separate copy of the Notice of Internet Availability and, if applicable, Annual Report on Form 10-K and other proxy materials to any stockholder at a shared address to which a single copy of any of those documents was delivered. To receive a separate copy of the Notice of Internet Availability and, if applicable, Annual Report on Form 10-K and other proxy materials, you may write our Investor Relations Department at Stoke Therapeutics, Inc., 45 Wiggins Avenue, Bedford, MA 01730, Attn: Investor Relations, submit a request on our website at https://www.stoketherapeutics.com/contact-us/ or calling (781) 303-8302.

Any stockholders who share the same address and currently receive multiple copies of our Notice of Internet Availability or Annual Report on Form 10-K and other proxy materials who wish to receive only one copy in the future can contact their bank, broker or other holder of record to request information about “householding” or our Investor Relations Department at the address or telephone number listed above.
