PROXY STATEMENT

FOR THE 2024 ANNUAL MEETING OF STOCKHOLDERS

To be held at 8:00 a.m. Pacific Time on Thursday, May 30, 2024

The information provided in the “question and answer” format below is for your convenience only and is merely a summary of the information contained in this proxy statement. You should read this entire proxy statement carefully.

QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND OUR ANNUAL MEETING

Why am I receiving these materials?

This proxy statement and the form of proxy are furnished in connection with the solicitation of proxies by our board of directors for use at the 2024 annual meeting of stockholders of Tenaya Therapeutics, Inc., a Delaware corporation, and any postponements, adjournments or continuations thereof. The annual meeting will be held on Thursday, May 30, 2024, at 8:00 a.m. Pacific Time. The annual meeting will be conducted virtually via a live audio webcast. You will be able to attend the annual meeting virtually by visiting www.proxydocs.com/TNYA, where you will be able to listen to the meeting live, submit questions and vote online during the meeting by entering the control number on your proxy card.

The Notice of Internet Availability of Proxy Materials, or Notice of Internet Availability, containing instructions on how to access this proxy statement, the accompanying notice of annual meeting and form of proxy, and our annual report, is first being sent or given on or about April 17, 2024, to all stockholders of record as of the close of business on April 1, 2024. The proxy materials and our annual report can be accessed as of April 17, 2024, by visiting www.proxydocs.com/TNYA. If you receive a Notice of Internet Availability, then you will not receive a printed copy of the proxy materials or our annual report in the mail unless you specifically request these materials. Instructions for requesting a printed copy of the proxy materials and our annual report are set forth in the Notice of Internet Availability.

What proposals will be voted on at the annual meeting?

The following proposals will be voted on at the annual meeting:

As of the date of this proxy statement, our management and board of directors were not aware of any other matters to be presented at the annual meeting.

How does the board of directors recommend that I vote on these proposals?

Our board of directors recommends that you vote your shares:

-1-

Who is entitled to vote at the annual meeting?

Holders of our common stock as of the close of business on April 1, 2024, the record date for the annual meeting, may vote at the annual meeting. As of the record date, there were 78,517,534 shares of our common stock outstanding. Each share of common stock is entitled to one vote on each matter properly brought before the annual meeting. Stockholders are not permitted to cumulate votes with respect to the election of directors.

Stockholders of Record. If your shares of common stock are registered directly in your name with our transfer agent, Computershare Trust Company, N.A., then you are considered the stockholder of record with respect to those shares, and the Notice of Internet Availability was sent directly to you by us. As a stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or to vote on your own behalf at the annual meeting. Throughout this proxy statement, we refer to these holders as “stockholders of record.”

Street Name Stockholders. If your shares are held in a brokerage account or by a broker, bank or other nominee, then you are considered the beneficial owner of shares held in street name, and the Notice of Internet Availability was forwarded to you by your broker, bank or other nominee, which is considered the stockholder of record with respect to those shares. As a beneficial owner, you have the right to direct your broker, bank or other nominee on how to vote the shares held in your account by following the instructions that your broker, bank or other nominee sent to you. Throughout this proxy statement, we refer to these holders as “street name stockholders.”

Is there a list of registered stockholders entitled to vote at the annual meeting?

A list of registered stockholders entitled to vote at the annual meeting will be made available for examination by any stockholder for any purpose germane to the meeting for a period of at least ten days prior to the meeting between the hours of 9:00 a.m. and 4:30 p.m. Pacific Time at our principal executive offices located at 171 Oyster Point Boulevard, Suite 500, South San Francisco, CA 94080 by contacting our corporate secretary.

What is the quorum requirement for the annual meeting?

A quorum is the minimum number of shares required to be present or represented at the annual meeting for the meeting to be properly held under our amended and restated bylaws (Bylaws) and Delaware law. The presence, in person (including virtually) or by proxy, of a majority of the voting power of our capital stock issued and outstanding and entitled to vote will constitute a quorum to transact business at the annual meeting. Abstentions, choosing to withhold authority to vote and broker non-votes are counted as present and entitled to vote for purposes of determining a quorum. Whether or not a quorum is present, the chairperson of the meeting may adjourn the meeting to another time or place.

How many votes are needed for approval of each proposal?

-2-

How do I vote and what are the voting deadlines?

Stockholders of Record. If you are a stockholder of record, you may vote in one of the following ways:

Street Name Stockholders. If you are a street name stockholder, then you will receive voting instructions from your broker, bank or other nominee. The availability of Internet and telephone voting options will depend on the voting process of your broker, bank or other nominee. We therefore recommend that you follow the voting instructions in the materials you receive. If your voting instruction form or notice of internet availability of proxy materials indicates that you may vote your shares through the proxyvote.com website, then you may vote those shares at the annual meeting with the control number indicated on that voting instruction form or notice of internet availability of proxy materials. Otherwise, you may not vote your shares at the annual meeting unless you obtain a legal proxy from your broker, bank or other nominee. We provide Internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your Internet access, such as usage charges from Internet access providers and telephone companies.

What if I do not specify how my shares are to be voted or fail to provide timely directions to my broker, bank or other nominee?

Stockholders of Record. If you are a stockholder of record and you submit a proxy, but you do not provide voting instructions, your shares will be voted:

-3-

In addition, if any other matters are properly brought before the annual meeting, the persons named as proxies will be authorized to vote or otherwise act on those matters in accordance with their judgment.

Street Name Stockholders. Brokers, banks and other nominees holding shares of common stock in street name for customers are generally required to vote such shares in the manner directed by their customers. In the absence of timely directions, your broker, bank or other nominee will have discretion to vote your shares on our sole routine matter: the proposal to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024. Your broker, bank or other nominee will not have discretion to vote on any other proposals, which are considered non-routine matters, absent direction from you. In the event that your broker, bank or other nominee votes your shares on our sole routine matter, but is not able to vote your shares on the non-routine matters, then those shares will be treated as broker non-votes with respect to the non-routine proposals. Accordingly, if you own shares through a nominee, such as a broker or bank, please be sure to instruct your nominee how to vote to ensure that your shares are counted on each of the proposals.

What are the effects of abstentions and broker non-votes?

An abstention represents a stockholder’s affirmative choice to decline to vote on a proposal. If a stockholder indicates on its proxy card that it wishes to abstain from voting its shares, or if a broker, bank or other nominee holding its customers’ shares of record causes abstentions to be recorded for shares, these shares will be considered present and entitled to vote at the annual meeting. As a result, abstentions will be counted for purposes of determining the presence or absence of a quorum and will also count as votes against a proposal in cases where approval of the proposal requires the affirmative vote of a majority of the shares present and entitled to vote thereon or a majority of the voting power of the shares of capital stock of the Company outstanding as of the record date and entitled to vote thereon (e.g., Proposal No. 2). However, because the outcome of Proposal No. 1 (election of directors) will be determined by a plurality vote, abstentions will have no impact on the outcome of such proposal as long as a quorum exists.

A broker non-vote occurs when a broker, bank or other nominee holding shares for a beneficial owner does not vote on a particular proposal because the broker, bank or other nominee does not have discretionary voting power with respect to such proposal and has not received voting instructions from the beneficial owner of the shares. Broker non-votes will be counted for purposes of calculating whether a quorum is present at the annual meeting but will not be counted for purposes of determining the number of votes cast. Therefore, a broker non-vote will make a quorum more readily attainable but will not otherwise affect the outcome of the vote on Proposals No. 1 and 2.

Can I change my vote or revoke my proxy?

Stockholders of Record. If you are a stockholder of record, you can change your vote or revoke your proxy before the annual meeting by:

-4-

Street Name Stockholders. If you are a street name stockholder, then your broker, bank or other nominee can provide you with instructions on how to change or revoke your proxy.

What do I need to do to attend the annual meeting?

We will be hosting the annual meeting via a live audio webcast only.

Stockholders of Record. If you were a stockholder of record as of the record date, then you may attend the annual meeting virtually, and will be able to submit your questions during the meeting and vote your shares electronically during the meeting. To attend and participate in the annual meeting, you must register in advance at www.proxydocs.com/TNYA prior to the deadline of 7:59 a.m. Pacific Time on May 29, 2024. Upon completing your registration, you will receive further instructions via email, including your unique link that will allow you to access the annual meeting and to submit questions during the annual meeting. Stockholders are already provided the opportunity to submit questions prior to the annual meeting at the time of registration. The annual meeting via a live audio only webcast will begin promptly at 8:00 a.m. Pacific Time. We encourage you to access the meeting prior to the start time. Online check-in will begin at 7:45 a.m. Pacific Time on May 30, 2024, and you should allow ample time for the check-in procedures.

Street Name Stockholders. If you were a street name stockholder as of the record date and your voting instruction form or notice of internet availability of proxy materials indicates that you may vote your shares through the proxyvote.com website, then you may access and participate in the annual meeting with the control number indicated on that voting instruction form or notice of internet availability of proxy materials. Otherwise, street name stockholders should contact their bank, broker or other nominee and obtain a legal proxy in order to be able to attend and participate in the annual meeting.

How can I get help if I have trouble checking in or listening to the annual meeting online?

We will have technicians ready to assist you with any technical difficulties you may have accessing the annual meeting. If you encounter any difficulties accessing the virtual-only annual meeting platform, including any difficulties voting or submitting questions, you may call the technical support number that will be posted in your instructional email.

Why is the annual meeting held virtually?

We believe that a virtual annual meeting allows for participation by a broader group of stockholders and reduces the costs to stockholders associated with holding an in-person meeting. The virtual meeting format is intended to facilitate a level of transparency as close as possible to an in-person meeting.

What is the effect of giving a proxy?

Proxies are solicited by and on behalf of our board of directors. Faraz Ali, our Chief Executive Officer, Leone D. Patterson, our Chief Financial and Business Officer, and Jennifer Drimmer Rokovich, our General Counsel and Corporate Secretary, have been designated as proxy holders for the annual meeting by our board of directors. When proxies are properly dated, executed and returned, the shares represented by such proxies will be voted at the annual meeting in accordance with the instructions of the stockholders. If the proxy is dated and signed, but no specific instructions are given, however, the shares will be voted in accordance with the recommendations of our board of directors on the proposals as described above. If any other matters are properly brought before the annual meeting, then the proxy holders will use their own judgment to determine how to vote your shares. If the annual meeting is postponed or adjourned, then the proxy holders can vote your shares on the new meeting date, unless you have properly revoked your proxy, as described above.

Who will count the votes?

A representative of Mediant Communications Inc. will tabulate the votes and act as inspector of election.

-5-

How can I contact Tenaya’s transfer agent?

You may contact our transfer agent, Computershare Trust Company, N.A., by telephone at 800-736-3001, or by writing Computershare Trust Company, N.A, at 150 Royall Street, Canton, Massachusetts 02021. You may also access instructions with respect to certain stockholders matters (e.g., change of address) via the Internet at www-us.computershare.com.

How are proxies solicited for the annual meeting and who is paying for such solicitation?

Our board of directors is soliciting proxies for use at the annual meeting by means of the proxy materials. We will bear the entire cost of proxy solicitation, including the preparation, assembly, printing, mailing and distribution of the proxy materials. Copies of solicitation materials will also be made available upon request to brokers, banks and other nominees to forward to the beneficial owners of the shares held of record by such brokers, banks or other nominees. The original solicitation of proxies may be supplemented by solicitation by telephone, electronic communications or other means by our directors, officers or employees. No additional compensation will be paid to these individuals for any such services, although we may reimburse such individuals for their reasonable out-of-pocket expenses in connection with such solicitation.

Where can I find the voting results of the annual meeting?

We will disclose voting results on a Current Report on Form 8-K that we will file with the SEC within four business days after the meeting. If final voting results are not available to us in time to file a Form 8-K, we will file a Form 8-K to publish preliminary results and will provide the final results in an amendment to the Form 8-K as soon as they become available.

Why did I receive a Notice of Internet Availability instead of a full set of proxy materials?

In accordance with the rules of the SEC we have elected to furnish our proxy materials, including this proxy statement and our annual report, primarily via the Internet. As a result, we are mailing to our stockholders a Notice of Internet Availability instead of a paper copy of the proxy materials. The Notice of Internet Availability contains instructions on how to access our proxy materials on the Internet, how to vote on the proposals, how to request printed copies of the proxy materials and our annual report, and how to request to receive all future proxy materials in printed form by mail or electronically by e-mail. We encourage stockholders to take advantage of the availability of the proxy materials on the Internet to help reduce our costs and the environmental impact of our annual meetings.

What does it mean if I receive more than one Notice of Internet Availability or more than one set of printed proxy materials?

If you receive more than one Notice of Internet Availability or more than one set of printed proxy materials, then your shares may be registered in more than one name and/or are registered in different accounts. Please follow the voting instructions on each Notice of Internet Availability or each set of printed proxy materials, as applicable, to ensure that all of your shares are voted.

I share an address with another stockholder, and we received only one paper copy of the Notice of Internet Availability or proxy statement and annual report. How may I obtain an additional copy of the Notice of Internet Availability or proxy statement and annual report?

We have adopted a procedure approved by the SEC called “householding,” under which we can deliver a single copy of the Notice of Internet Availability and, if applicable, the proxy statement and annual report, to multiple stockholders who share the same address unless we receive contrary instructions from one or more stockholders. This procedure reduces our printing and mailing costs. Stockholders who participate in householding will

continue to be able to access and receive separate proxy cards. Upon written or oral request, we will deliver promptly a separate copy of the Notice of Internet Availability and, if applicable, the proxy statement and annual report, to any stockholders at a shared address to which we delivered a single copy of these documents. To receive a separate copy, or, if you are receiving multiple copies, to request that we only send a single copy of next year’s Notice of Internet Availability or proxy statement and annual report, as applicable, you may contact us as follows:

For a stockholder proposal to be considered for inclusion in our proxy statement for our 2025 annual meeting of stockholders, our corporate secretary must receive the written proposal at our principal executive offices not later than December 18, 2024.

Our Bylaws also establish an advance notice procedure for stockholders who wish to present a proposal before an annual meeting of stockholders but do not intend for the proposal to be included in our proxy statement. Our Bylaws provide that the only business that may be conducted at an annual meeting is business that is (i) specified in our proxy materials with respect to such meeting, (ii) otherwise properly brought before the annual meeting by or at the direction of the our board of directors, or (iii) properly brought before the annual meeting by a stockholder of record entitled to vote at the annual meeting who has delivered timely written notice to our corporate secretary, which notice must contain the information specified in our Bylaws, provided that clause (iii) is the exclusive means under our Bylaws for stockholders to propose business other than such proposals as are properly made pursuant to the Exchange Act. To be timely for our 2025 annual meeting of stockholders, our corporate secretary must receive the written notice at our principal executive offices:

In the event that we hold our 2025 annual meeting of stockholders more than 25 days before or after the first anniversary of the date of this year’s annual meeting, then notice of a stockholder proposal that is not intended to be included in our proxy statement must be received no earlier than 8:00 a.m., Eastern time, on the 120th day

If a stockholder who has notified us of his, her or its intention to present a proposal at an annual meeting does not appear to present his, her or its proposal at such annual meeting, we are not required to present the proposal for a vote at such annual meeting.

In addition, our Bylaws permit stockholders to nominate directors for election at an annual meeting of stockholders. To nominate a director, the stockholder must provide the information required by our Bylaws and give timely notice to our corporate secretary in accordance with our Bylaws, which, in general, require that the notice be received by our corporate secretary within the time period described above under “Stockholder Proposals” for stockholder proposals that are not intended to be included in a proxy statement.

BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

Composition of the Board

Our board of directors currently consists of ten (10) directors, nine (9) of whom are independent under the listing standards of The Nasdaq Stock Market LLC, or Nasdaq. Our board of directors is divided into three classes with staggered three-year terms. Thus, at each annual meeting of stockholders, a class of directors will be elected for a three-year term to succeed the class whose term is then expiring.

Upon the recommendation of our corporate governance and nominating committee, we are nominating Faraz Ali, M.B.A., June Lee, M.D. and Deepak Srivastava, M.D., as Class III directors at the annual meeting. If elected, Drs. Lee and Srivastava and Mr. Ali will each hold office for a three-year term until the annual meeting of stockholders to be held in 2027 or until their successors are duly elected and qualified.

Director Independence

Our common stock is listed on the Nasdaq Global Select Market. Under the rules of Nasdaq, independent directors must comprise a majority of our board of directors. A director will only qualify as “independent” under Nasdaq listing rules if, in the opinion of our board of directors, the director does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In addition, the Nasdaq listing rules require that, subject to specified exceptions, each member of our audit, compensation and corporate governance and nominating committees be independent.

Audit committee members must also satisfy the additional independence criteria set forth in Rule 10A-3 under the Exchange Act, and Nasdaq listing rules applicable to audit committee members. Compensation committee members must also satisfy the additional independence criteria set forth in Rule 10C-1 under the Exchange Act and Nasdaq listing rules applicable to compensation committee members.

Our board of directors has undertaken a review of the independence of each of our directors. Based on information provided by each director concerning his or her background, employment and affiliations, our board of directors has determined that each of Drs. Chen, Goeddel, Lee, Srivastava, Stehman-Breen and Williams, Mses. Burroughs and Parschauer and Mr. Walsh, representing nine of our ten directors, do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is an “independent director” as defined under the listing standards of Nasdaq. Mr. Ali is not considered an independent director because of his position as our Chief Executive Officer.

In making these determinations, our board of directors considered the current and prior relationships that each non-employee director has with our company 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, and the transactions involving them described in the section titled “Related Person Transactions.”

-13-

There are no family relationships among any of our directors, director nominees or executive officers.

Board Leadership Structure

Our board of directors is currently chaired by Dr. Goeddel. As a general policy, our board of directors believes that separation of the positions of Chair of our board of directors and Chief Executive Officer reinforces the independence of our board of directors from management, creates an environment that encourages objective oversight of management’s performance and enhances the effectiveness of our board of directors as a whole. As such, Mr. Ali serves as our Chief Executive Officer while Dr. Goeddel serves as the Chair of our board of directors but is not an officer. We currently expect and intend the positions of Chair of our board of directors and Chief Executive Officer to continue to be held by two individuals in the future.

Role of Board in Risk Oversight Process

Risk is inherent with every business, and we face a number of risks, including strategic, financial, business and operational, legal and compliance and reputational. We have designed and implemented processes to manage risk in our operations. Management is responsible for the day-to-day management of risks the company faces, while our board of directors, as a whole and assisted by its committees, has responsibility for the oversight of risk management. Our board reviews strategic and operational risk in the context of discussions, question and answer sessions, and reports from the management team at each regular board meeting, receives reports on all significant committee activities at each regular board meeting, and evaluates the risks inherent in significant transactions.

In addition, our board has tasked designated standing committees with oversight of certain categories of risk management.

Our board of directors believes its current leadership structure supports the risk oversight function of the board.

Board Committees

Our board of directors has established the following standing committees of the board: audit committee; compensation committee; corporate governance and nominating committee; and science and technology committee. The composition and responsibilities of each of the committees of our board of directors is described below.

Audit Committee

The current members of our audit committee are Mses. Burroughs and Parschauer and Mr. Walsh. Mr. Walsh is the chairperson of our audit committee. Our board of directors has determined that each member of our audit

Our board of directors has determined that Mr. Walsh is an audit committee financial expert within the meaning of Item 407(d) of Regulation S-K. Our audit committee is responsible for, among other things:

Our audit committee operates under a written charter that satisfies the applicable rules and regulations of the SEC and the listing standards of Nasdaq.

During 2023, our audit committee held four meetings.

Dr. Srivastava is the chairperson of our corporate governance and nominating committee. Our board of directors has determined that each member of our corporate governance and nominating committee meets the requirements for independence for corporate governance and nominating committee members under the listing standards of Nasdaq. Our corporate governance and nominating committee is responsible for, among other things:

Our corporate governance and nominating committee operates under a written charter that satisfies the applicable listing standards of Nasdaq. A copy of the charter of our corporate governance and nominating committee is available on our website at https://investors.tenayatherapeutics.com/corporate-governance/governance-overview.

Science and Technology Committee

The current members of our science and technology committee are Drs. Lee, Srivastava, Stehman-Breen and Williams. Dr. Stehman-Breen is the chairperson of our science and technology committee. Our board of directors has determined that each member of our science and technology committee meets the requirements for independence under the listing standards of Nasdaq. Our science and technology committee is responsible for, among other things:

Our science and technology committee operates under a written charter. A copy of the charter of our science and technology committee is available on our website at https://investors.tenayatherapeutics.com/corporate-governance/governance-overview. During 2023, our science and technology committee held one meeting.

Attendance at Board and Stockholders Meetings

During our fiscal year ended December 31, 2023, our board of directors held five meetings (including regularly scheduled and special meetings), and each director, other than Dr. Stehman-Breen, attended at least 75% of the aggregate of (1) the total number of meetings of the board of directors held during the period for which he or she has been a director and (2) the total number of meetings held by all committees on which he or she served during the periods that he or she served. Dr. Stehman-Breen’s absences were due principally to scheduling conflicts with certain activities and meetings in connection with her service as Chief Executive Officer of Chroma Medicine.

Although we do not have a formal policy regarding attendance by members of our board of directors at the annual meetings of stockholders, we encourage, but do not require, directors to attend. All our directors serving at the time were in attendance at the 2023 Annual Meeting of Stockholders.

Compensation Committee Interlocks and Insider Participation

During 2023, the members of our compensation committee were Drs. Lee (joined in September 2023), Stehman-Breen (resigned in September 2023) and Williams and Mr. Walsh. None of the members of our compensation committee is or has been an officer or employee of our company. None of our executive officers currently serves, or in the past fiscal year has served, as a member of the board of directors or compensation committee (or other board committee performing equivalent functions) of any entity that has one or more executive officers serving on our board of directors or compensation committee.

Considerations in Evaluating Director Nominees

Our corporate governance and nominating committee uses a variety of methods for identifying and evaluating potential director nominees. In its evaluation of director candidates, including the current directors eligible for re-election, our corporate governance and nominating committee will consider the current size and composition of our board of directors and the needs of our board of directors and the respective committees of our board of directors and other director qualifications. While our board has not established minimum qualifications for board members, some of the factors that our corporate governance and nominating committee considers in assessing director nominee qualifications include, without limitation, issues of character, professional ethics and integrity, judgment, business experience and diversity, and with respect to diversity, such factors as race, ethnicity, gender,

-17-

differences in professional background, age and geography, as well as other individual qualities and attributes that contribute to the total mix of viewpoints and experience represented on our board. Although our board of directors does not maintain a specific policy with respect to board diversity, our board of directors believes that the board should be a diverse body, and the corporate governance and nominating committee considers a broad range of perspectives, backgrounds and experiences.

If our corporate governance and nominating committee determines that an additional or replacement director is required, then the committee may take such measures as it considers appropriate in connection with its evaluation of a director candidate, including candidate interviews, inquiry of the person or persons making the recommendation or nomination, engagement of an outside search firm to gather additional information, or reliance on the knowledge of the members of the committee, board or management.

After completing its review and evaluation of director candidates, our corporate governance and nominating committee recommends to our full board of directors the director nominees for selection. Our corporate governance and nominating committee has discretion to decide which individuals to recommend for nomination as directors and our board of directors has the final authority in determining the selection of director candidates for nomination to our board.

Stockholders Recommendations and Nominations to our Board of Directors

Our corporate governance and nominating committee will consider recommendations and nominations for candidates to our board of directors from stockholders in the same manner as candidates recommended to the committee from other sources, so long as such recommendations and nominations comply with our Amended and Restated Certificate of Incorporation and Bylaws, all applicable company policies and all applicable laws, rules and regulations, including those promulgated by the SEC. Our corporate governance and nominating committee will evaluate such recommendations in accordance with its charter, our Bylaws and corporate governance guidelines and the director nominee criteria described above.

A stockholder who wants to recommend a candidate to our board of directors should direct the recommendation in writing by letter to our corporate secretary at Tenaya Therapeutics, Inc., 171 Oyster Point Boulevard, Suite 500, South San Francisco, CA 94080, Attention: Corporate Secretary. Such recommendation must include the candidate’s name, home and business contact information, detailed biographical data, relevant qualifications, a signed letter from the candidate confirming willingness to serve, information regarding any relationships between the candidate and us and evidence of the recommending stockholders’ ownership of our capital stock. Such recommendation must also include a statement from the recommending stockholder(s) in support of the candidate. Our corporate governance and nominating committee has discretion to decide which individuals to recommend for nomination as directors.

Under our Bylaws, stockholders may also directly nominate persons for our board of directors. Any nomination must comply with the requirements set forth in our Bylaws and the rules and regulations of the SEC and should be sent in writing to our corporate secretary at the address above. To be timely for our 2025 annual meeting of stockholders, nominations must be received by our corporate secretary observing the deadlines discussed above under “Questions and Answers About The Proxy Materials—What is the deadline to propose actions for consideration at next year’s annual meeting of stockholders or to nominate individuals to serve as directors?”

Corporate Governance Guidelines and Code of Business Conduct and Ethics

In addition, 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.

Director Compensation

Under our Outside Director Compensation Policy, non-employee directors receive compensation in the form of cash and equity, as described below. We also reimburse our non-employee directors for expenses incurred in connection with attending board and committee meetings, as well as continuing director education.

Cash Compensation

Prior to January 1, 2024, the Outside Director Compensation Policy provides for each non-employee director to be paid an annual cash retainer of $35,000. Effective January 1, 2024, each non-employee director is to be paid an annual cash retainer of $40,000. In addition, each non-employee director who serves as a chair or chair or member of a committee will be entitled to receive the following cash compensation for his or her services:

* The Outside Director Compensation Policy was amended in September 2023 to add the annual retainers for the chair and other members of our science and technology committee.

Each non-employee director who serves as a committee chair will receive only the cash retainer fee as the chair of the committee but not the cash retainer fee as a member of that committee. These fees to our non-employee directors are paid quarterly in arrears on a prorated basis. Under our Outside Director Compensation Policy, we also will reimburse our non-employee directors for reasonable travel expenses to attend meetings of our board of directors and its committees.

Equity Compensation

Initial Award. Pursuant to our Outside Director Compensation Policy, each person who first becomes a non-employee director after the initial effective date of such policy will receive, on the first trading day on or after the date that the person first becomes a non-employee director, an initial award, or the Initial Award, of stock options to purchase shares of our common stock with a grant date fair value as determined in accordance with U.S. GAAP equal to $320,000. However, beginning in December 2022, our Outside Director Compensation Policy provided that, notwithstanding the foregoing, with respect to Initial Awards granted on or following the December 2022 restatement date, no more than 40,000 shares of our common stock could be subject to an Initial Award, and our Outside Director Compensation Policy was restated again in March 2023 to change this Initial Award limit to 68,000 shares for Initial Awards granted on or after the March 2023 restatement date. The Initial Award will be scheduled to vest in equal installments as to one thirty-sixth of the shares of our common stock subject at grant to the Initial Award on a monthly basis following the Initial Award’s grant date, on the same day of the month as the grant date, subject to continued services to us through the applicable vesting dates. If the person was a member of our board of directors and also an employee, then becoming a non-employee director due to termination of employment will not entitle the person to an Initial Award.

-20-

Annual Award. Pursuant to our Outside Director Compensation Policy, each non-employee director who has served continuously as an outside director since the date of the most recently preceding annual meeting of stockholders will automatically receive, on the first trading day immediately after the date of each annual meeting of our stockholders, an annual award, or the Annual Award, of stock options to purchase shares of our common stock with a grant date fair value as determined in accordance with U.S. GAAP equal to $160,000. Our Outside Director Compensation Policy provides that, in the case of a director who joined our board after the immediately preceding annual meeting of stockholders, the number of shares subject to his or her first Annual Award will be prorated for the months the director served prior to and including the date of the annual meeting at which the Annual Award is to be granted. However, beginning in December 2022, our Outside Director Compensation Policy provided that, notwithstanding the formula stated above, with respect to Annual Awards granted on or following the December 2022 restatement date, no more than 20,000 shares of our common stock could be subject to an Annual Award, and the March 2023 restatement changed this Annual Award limit to 34,000 shares for Annual Awards granted on or after the March 2023 restatement date. Each Annual Award will be scheduled to vest in full upon the first anniversary of the date of the grant, or if earlier, the day immediately before the date of the next annual meeting that occurs after the Annual Award’s grant date, subject to the outside director remaining a service provider through the applicable vesting date.

Change in Control. In the event of a change in control, as defined in our 2021 Equity Incentive Plan, each non-employee director’s then outstanding equity awards covering shares of our common stock will accelerate vesting in full, provided that he or she remains a non-employee director through the date of our change in control.

Other Award Terms. Each Initial Award and Annual Award will be granted under our 2021 Equity Incentive Plan (or its successor plan, as applicable) and form of award agreement under such plan. These awards will have a maximum term to expiration of ten years from their grant and a per-share exercise price equal to 100% of the fair market value of a share of our common stock on the award’s grant date.

Director Compensation Limits. Our Outside Director Compensation Policy provides that in any fiscal year, a non-employee director may be granted equity awards or provided cash or other compensation with an aggregate value of no more than $500,000 (with the value of equity awards based on its grant date fair value determined in accordance with U.S. GAAP for purposes of this limit). Equity awards granted or other compensation provided to a non-employee director while he or she was an employee or consultant (other than a non-employee director), or granted or provided before the effective date of the registration statement related to our initial public offering, do not count toward this annual limit.

Director Compensation for Fiscal 2023

The following table sets forth information regarding the total compensation awarded to, earned by or paid to our non-employee directors for their service on our board of directors, for the fiscal year ended December 31, 2023. Directors who are also our employees receive no additional compensation for their service as directors. During 2023, Mr. Ali was an employee and executive officer of the company and therefore, did not receive compensation as a director. See “Executive Compensation” for additional information regarding Mr. Ali’s compensation.

PROPOSAL NO. 1

ELECTION OF CLASS III DIRECTORS

Our board of directors currently consists of ten members. In accordance with our Amended and Restated Certificate of Incorporation, our board of directors is divided into three classes with staggered three-year terms. At the annual meeting, three Class III directors will be elected for a three-year term to succeed the same class whose term is then expiring. Each director’s term continues until the expiration of the term for which such director was elected and until such director’s successor is elected and qualified or until such director’s earlier death, resignation or removal.

Nominees

Our corporate governance and nominating committee has recommended, and our board of directors has approved, Faraz Ali, M.B.A., June Lee, M.D. and Deepak Srivastava, M.D., as nominees for election as Class III directors at the annual meeting. If elected, each of Drs. Lee and Srivastava and Mr. Ali will serve as a Class III director until the 2027 annual meeting of stockholders and until his or her respective successor is elected and qualified or until his or her earlier death, resignation or removal. For more information concerning the nominees, please see the section titled “Board of Directors and Corporate Governance.”

Each of Drs. Lee and Srivastava and Mr. Ali have agreed to serve as directors if elected, and management has no reason to believe that they will be unavailable to serve. In the event a nominee is unable or declines to serve as a director at the time of the annual meeting, proxies will be voted for any nominee designated by the present board of directors to fill the vacancy.

Vote Required

Each director is elected by a plurality of the voting power of the shares present in person (including virtually) or represented by proxy at the meeting and entitled to vote on the election of directors. Because the outcome of this proposal will be determined by a plurality vote, any shares not voted FOR a particular nominee, whether as a result of choosing to WITHHOLD authority to vote or a broker non-vote, will have no effect on the outcome of the election.

Board Recommendation

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE ELECTION OF EACH OF THE DIRECTOR NOMINEES NAMED ABOVE.

PROPOSAL NO. 2

RATIFICATION OF APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Our audit committee has appointed Deloitte & Touche LLP as our independent registered public accounting firm to audit our financial statements for our fiscal year ending December 31, 2024. Deloitte & Touche LLP served as our independent registered public accounting firm for the fiscal year ended December 31, 2023.

At the annual meeting, we are asking our stockholders to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024. Our audit committee is submitting the appointment of Deloitte & Touche 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. Notwithstanding the appointment of Deloitte & Touche LLP, and even if our stockholders ratify the appointment, our audit committee, in its discretion, may appoint another independent registered public accounting firm at any time during our fiscal year if our audit committee believes that such a change would be in the best interests of our company and our stockholders. If our stockholders do not ratify the appointment of Deloitte & Touche LLP, then our audit committee may reconsider the appointment. One or more representatives of Deloitte & Touche LLP are expected to be present at the annual meeting, and they will have an opportunity to make a statement and are expected to be available to respond to appropriate questions from our stockholders.

Fees Paid to the Independent Registered Public Accounting Firm

The following table presents fees for professional audit services and other services rendered to us by Deloitte & Touche LLP for our fiscal years ended December 31, 2023, and 2022.

Auditor Independence

In 2023, there were no other professional services provided by Deloitte & Touche LLP, other than those listed above, that would have required our audit committee to consider their compatibility with maintaining the independence of Deloitte & Touche LLP.

Audit Committee Policy on Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm

Our audit committee has established a policy governing our use of the services of our independent registered public accounting firm. Under this policy, our audit committee is required to pre-approve all services performed

-24-

by our independent registered public accounting firm in order to ensure that the provision of such services does not impair such accounting firm’s independence. All fees paid to Deloitte & Touche LLP for our fiscal year ended December 31, 2023, were pre-approved by our audit committee.

Vote Required

The ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024, requires the affirmative vote of a majority of the voting power of the shares present in person (including virtually) or represented by proxy at the annual meeting and entitled to vote thereon. Abstentions will have the same effect as a vote AGAINST this proposal. Because this is a routine proposal, your broker, bank or other nominee will have discretion to vote your shares on this routine matter. See “What if I do not specify how my shares are to be voted or fail to provide timely directions to my broker, bank or other nominee?” above.

AUDIT COMMITTEE REPORT

The audit committee is a committee of the board of directors comprised solely of independent directors as required by the listing standards of the Nasdaq Stock Market LLC and the rules and regulations of the Securities and Exchange Commission (the SEC). The composition of the audit committee, the attributes of its members and the responsibilities of the audit committee, as reflected in its charter, are intended to be in accordance with applicable requirements for corporate audit committees. The audit committee operates under a written charter approved by the board of directors. The audit committee reviews and assesses the adequacy of its charter and the audit committee’s performance on an annual basis.

With respect to the Company’s financial reporting process, the Company’s management is responsible for (1) establishing and maintaining internal controls and (2) preparing the Company’s financial statements. The Company’s independent registered public accounting firm, Deloitte & Touche LLP (Deloitte), is responsible for performing an independent audit of the Company’s financial statements. It is the responsibility of the audit committee to oversee these activities. It is not the responsibility of the audit committee to prepare the Company’s financial statements. These are the fundamental responsibilities of management.

In the performance of its oversight function, the audit committee has:

Based on the audit committee’s review and discussions with management and Deloitte, the audit committee recommended to the board of directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, for filing with the SEC.

Respectfully submitted by the members of the audit committee of the board of directors:

Jeffrey T. Walsh (Chair)

Amy Burroughs

Karah Parschauer

This audit committee report shall not be deemed to be “soliciting material” or to be “filed” with the SEC or subject to Regulation 14A promulgated by the SEC or to the liabilities of Section 18 of the Exchange Act, and shall not be deemed incorporated by reference into any prior or subsequent filing by the Company under the Securities Act of 1933, as amended, or the Exchange Act, except to the extent the Company specifically requests that the information be treated as “soliciting material” or specifically incorporates it by reference.

EXECUTIVE COMPENSATION

Processes and Procedures for Compensation Decisions

Our compensation committee is responsible for the executive compensation programs for our executive officers and reports to our board of directors on its discussions, decisions and other actions. Typically, our chief executive officer makes recommendations to our compensation committee, often attends committee meetings and is involved in the determination of compensation for the respective executive officers who report to him, except that the chief executive officer does not make recommendations as to his own compensation. Our chief executive officer makes recommendations to our compensation committee regarding short- and long-term incentive compensation for all executive officers (other than himself) based on our results, an individual executive officer’s contribution toward these results and performance toward individual goal achievement. Our compensation committee then reviews the recommendations and other data furnished by its independent compensation consultant. Our compensation committee makes decisions as to total compensation for each executive officer other than the chief executive officer, although it may instead, in its discretion, make recommendations to our board of directors regarding executive compensation for its approval. Our compensation committee makes recommendations to our board of directors regarding our chief executive officer’s compensation and our board of directors makes decisions as to such compensation.

Our compensation committee is authorized to retain the services of one or more executive compensation advisors, as it sees fit, in connection with the establishment of our compensation programs and related policies. Beginning in August 2022, our compensation committee retained Pearl Meyer, an independent compensation and leadership consulting firm, to provide it with information, recommendations and other advice relating to executive compensation and non-employee director compensation on an ongoing basis. Pearl Meyer served at the discretion of our compensation committee. As part of its engagement, Pearl Meyer assisted our compensation committee in developing a group of peer companies to help us determine the appropriate level of overall compensation for our executive officers, as well as assess each separate element of compensation, with a goal of ensuring that the compensation we offer to our executive officers is competitive and fair.

Our named executive officers, consisting of our principal executive officer and the two most highly compensated executive officers (other than our principal executive officer), as of December 31, 2023, were:

Executive Change in Control and Severance Plan

Our board of directors adopted an Executive Change in Control and Severance Plan, or the Executive Severance Plan, pursuant to which our named executive officers and certain other key employees are eligible to receive severance benefits, as specified in and subject to the employee signing a participation agreement under our Executive Severance Plan. This Executive Severance Plan was initially developed with input from our

-29-

compensation committee’s then-current independent compensation consultant regarding severance practices at comparable companies, and was most recently amended in June 2023 with input from Pearl Meyer (the “June 2023 amendment”). It is designed to attract, retain and reward senior level employees. The Executive Severance Plan will be in lieu of any other severance payments and benefits to which such key employee was entitled prior to signing the participation agreement.

Each of our named executive officers has signed a participation agreement under our Executive Severance Plan that was amended in connection with the June 2023 amendment providing for the rights to the applicable payments and benefits described below.

In the event of a “qualifying termination” of the employment of a named executive officer, which generally includes a termination of employment by us for a reason other than “cause” or the named executive officer’s death or “disability” (as such terms are defined in our Executive Severance Plan), but in the case of Mr. Ali includes a termination of employment by him for “good reason” or by us for a reason other than “cause” or his death or disability, in all cases, that occurs outside the change in control period (as described below), then the named executive officer will be entitled to the following payments and benefits:

In the event of a termination of employment by the named executive officer for “good reason” or by us for a reason other than “cause” or the named executive officer’s death or disability, in each case, within the “change in control period” (as described below), then the named executive officer will be entitled to the following payments and benefits:

The “change in control” period is the period beginning three months prior to and ending 12 months following a “change in control” (as defined in our Executive Severance Plan). Prior to the June 2023 amendment, the change in control period that applied to our named executive officers other than Mr. Ali was the period beginning on the date of a change in control and ending 12 months following a change in control, and the change in control period that applied to Mr. Ali was the period beginning on the date of a change in control and ending 18 months following a change in control.

The receipt of the payments and benefits provided for under the Executive Severance Plan described above is conditioned on the named executive officer signing and not revoking a separation and release of claims

-30-

agreement and such release becoming effective and irrevocable no later than the 60^th day following the named executive officer’s involuntary termination of employment, as well as continued compliance with the invention assignment and confidentiality agreement applicable to the named executive officer.

In addition, if any of the payments or benefits provided for under the Executive Severance Plan or otherwise payable to a named executive officer would constitute “parachute payments” within the meaning of Section 280G of the Code and could be subject to the related excise tax, the named executive officer will receive either full payment of such payments and benefits or such lesser amount that would result in no portion of the payments and benefits being subject to the excise tax, whichever results in the greater amount of after-tax benefits to them. The Executive Severance Plan does not require us to provide any tax gross-up  payments to the named executive officers.

Equity Plans

Our 2016 Equity Incentive Plan and our 2021 Equity Incentive Plan each provide that in the event of a “merger” or “change in control,” as defined thereunder, each outstanding award will be treated as the administrator determines, except that if a successor corporation or its parent or subsidiary does not assume or substitute an equivalent award for any outstanding award, then such award will fully vest, all restrictions on such award will lapse, all performance goals or other vesting criteria applicable to such award will be deemed achieved at 100% of target levels, and such award will become fully exercisable, if applicable, for a specified period prior to the transaction and, if not exercised during the specified period, will terminate upon the expiration of such period.

Executive Incentive Compensation Plan

Our board of directors adopted the Executive Incentive Compensation Plan, or the Incentive Compensation Plan, and bonuses to our named executive officers for 2023 were subject to the terms and conditions of, and were paid under this plan. Our Incentive Compensation Plan allows our compensation committee to grant incentive awards, generally payable in cash, to employees selected by our compensation committee, including our executive officers, based upon performance goals established by our compensation committee.

Under our Incentive Compensation Plan, our compensation committee will determine the performance goals, if any, applicable to any award, which goals may include, without limitation, goals related to research and development, regulatory milestones or regulatory-related goals, gross margin, financial milestones, new product or business development, operating margin, product release timelines or other product release milestones, publications, cash flow, procurement, savings, internal structure, leadership development, project, function or portfolio-specific milestones, license or research collaboration agreements, capital raising, initial public offering preparations, patentability and individual objectives such as peer reviews or other subjective or objective criteria. The performance goals may differ from participant to participant and from award to award.

The compensation committee of our board of directors administers our Incentive Compensation Plan and may, in its sole discretion and at any time, increase, reduce or eliminate a participant’s actual award, and/or increase, reduce or eliminate the amount allocated to the bonus pool for a particular performance period. The actual award may be below, at or above a participant’s target award, in the discretion of the administrator. The administrator may determine the amount of any increase, reduction or elimination on the basis of such factors as it deems relevant, and it is not required to establish any allocation or weighting with respect to the factors it considers.

Actual awards generally will be paid in cash (or its equivalent) only after they are earned, and, unless otherwise determined by the administrator, to earn an actual award a participant must be employed by us through the date the actual award is paid. The compensation committee may reserve the right to settle an actual award with a grant of an equity award under our then-current equity compensation plan, which equity award may have such terms and conditions, including vesting, as the compensation committee determines. Payment of awards will occur as soon as practicable after they are earned, but no later than the dates set forth in our Incentive Compensation Plan.

-31-

Our board of directors and our compensation committee have the authority to amend, suspend or terminate our Incentive Compensation Plan, provided such action does not impair the existing rights of any participant with respect to any earned awards.

Clawback Policy

In November 2023, our compensation committee adopted a compensation recovery policy (the “Clawback Policy”), in compliance with SEC rules and applicable Nasdaq Listing Rules. Consistent with these requirements, the Clawback Policy provides that, subject to the limited exemptions permitted under these requirements, if we are required to prepare an accounting restatement due to our material noncompliance with financial reporting requirements under applicable securities laws, we must clawback from covered executive officers any incentive-based compensation received by them while he/she was an executive officer, during the applicable recoupment period (which generally includes the three completed fiscal years prior to the date we conclude, or reasonably should have concluded, that we are required to prepare, or the date on which a court, regulator or other legally authorized body directs us to prepare, a financial restatement) that was in excess of what they would have received had their incentive compensation been determined based on the restated amounts.

401(k) Plan

We maintain a 401(k) retirement savings plan, or 401(k) plan, for the benefit of our employees, including our named executive officers, who satisfy certain eligibility requirements. Our 401(k) plan provides eligible employees with an opportunity to save for retirement on a tax-advantaged basis. Under our 401(k) plan, eligible employees may elect to defer a portion of their compensation, within the limits prescribed by the Code and the applicable limits under the 401(k) plan (generally, up to 90% of the employee’s eligible compensation), on a pre-tax or after-tax (Roth) basis, through contributions to the 401(k) plan. All of a participant’s contributions into the 401(k) plan are 100% vested when contributed. The 401(k) plan permits us to make matching contributions and profit-sharing contributions to eligible participants. For 2023, we matched pre-tax contributions dollar-for-dollar up to $1,000. The 401(k) plan is intended to qualify under Sections 401(a) and 501(a) of the Code. As a tax-qualified retirement plan, pre-tax contributions to the 401(k) plan and earnings on those pre-tax contributions are not taxable to the employees until distributed from the 401(k) plan, and earnings on Roth contributions are not taxable when distributed from the 401(k) plan.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth the beneficial ownership of our common stock as of March 31, 2024, by:

We have determined beneficial ownership in accordance with the rules of the SEC, and thus it represents sole or shared voting or investment power with respect to our securities. Unless otherwise indicated, to our knowledge, the persons or entities identified in the table have sole voting power and sole investment power with respect to all shares shown as beneficially owned by them, subject to community property laws where applicable.

We have based our calculation of the percentage of beneficial ownership on 78,517,534 shares of our common stock outstanding as of March 31, 2024. We have deemed shares of our common stock subject to stock options that are currently exercisable or exercisable within 60 days of March 31, 2024, to be outstanding and to be beneficially owned by the person holding the stock option for the purpose of computing the percentage ownership of that person. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person.

Unless otherwise indicated, the address for each person or entity listed in the table is c/o Tenaya Therapeutics, Inc., 171 Oyster Point Boulevard, Suite 500, South San Francisco, CA 94080.

RELATED PERSON TRANSACTIONS

The following is a description of each transaction since the beginning of our last fiscal year, and each currently proposed transaction, in which:

Investors’ Rights Agreement

We are party to an investors’ rights agreement, as amended and restated, with certain holders of our capital stock, including entities affiliated with The Column Group III, LP, The Column Group III-A, LP, Casdin Partners Master Fund, L.P., and Casdin Private Growth Equity Fund, L.P. Under our investors’ rights agreement, among other things, certain holders of our capital stock have the right to demand that we file a registration statement or request that their shares of our capital stock be covered by a registration statement that we are otherwise filing.

Stock and Pre-funded Warrant Issuances

In the February Offering, we issued and sold an aggregate of 8,888,890 shares of our common stock at a purchase price of $4.50 per share and, to certain investors in lieu of common stock, pre-funded warrants to purchase 2,222,271 shares of our common stock at a price of $4.499 per pre-funded warrant. We received total net proceeds of $46.5 million after deducting underwriting discounts and commissions of $3.0 million and offering expenses of $0.5 million.

Purchasers of our stock and pre-funded warrants include venture capital funds that beneficially own more than 5% of our outstanding capital stock and/or are or were represented on our board of directors. The following table presents the number of shares and preferred stock warrants and total purchase price paid by these entities.

Indemnification Agreements

Our Amended and Restated Certificate of Incorporation contains provisions limiting the liability of the members of our board of directors, and our Bylaws provide that we will indemnify each of our officers and the members of our board of directors to the fullest extent permitted under Delaware law, subject to certain exceptions. Our Amended and Restated Certificate of Incorporation and Bylaws also provide our board of directors with discretion to indemnify our employees and other agents when it determines to be appropriate. In addition, we

-38-

have entered into an indemnification agreement with each of our executive officers and the members of our board of directors requiring us to indemnify them.

Policies and Procedures for Related Person Transactions

Our audit committee will have the primary responsibility for reviewing and approving or disapproving “related party transactions,” which are transactions between us and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or will have a direct or indirect material interest. The charter of our audit committee provides that our audit committee shall review and approve in advance any related party transaction.

Our board of directors adopted a formal written policy governing our entry into any transaction that exceeds $120,000 and in which any related person has a direct or indirect material interest. The policy provides that management shall present related party transactions to the audit committee for approval. The policy does not prevent management from entering into any related party transaction without prior approval of the audit committee, so long as such related party transaction is thereafter presented to the audit committee for ratification. In approving or rejecting any such transaction, our audit committee is to consider the relevant facts and circumstances available and deemed relevant to our audit committee, including 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.

OTHER MATTERS

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires that our directors and executive officers, and persons who own more than 10% of our common stock, file reports of ownership and changes in ownership with the SEC. Based on our review of such filings and written representations from certain reporting persons that no Form 5 is required, we believe that during the fiscal year ended December 31, 2023, all directors, executive officers and greater than 10% stockholders complied with all Section  16(a) filing requirements applicable to them.
