PROXY STATEMENT

FOR THE ANNUAL GENERAL MEETING OF SHAREHOLDERS

TO BE HELD ON JUNE 8, 2023

This proxy statement (the “Proxy Statement”) and our annual report for the fiscal year ended December 31, 2022 (the “Annual Report” and, together with the Proxy Statement, the “proxy materials”) are being furnished by and on behalf of the board of directors (the “Board” or the “Board of Directors”) of MeiraGTx Holdings plc (the “Company,” “MeiraGTx,” “we,” “us,” or “our”), in connection with our 2023 annual general meeting of shareholders (the “Annual Meeting”).

GENERAL INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

When and where will the Annual Meeting be held?

The Annual Meeting will be held on Thursday, June 8, 2023 at 10:00 a.m., Eastern Time, via live webcast by visiting www.virtualshareholdermeeting.com/MGTX2023.

What is the purpose of the Annual Meeting?

The purpose of the Annual Meeting is to vote on the following items described in this Proxy Statement:

Are there any matters to be voted on at the Annual Meeting that are not included in this Proxy Statement?

At the date this Proxy Statement went to press, we did not know of any matters to be properly presented at the Annual Meeting other than those referred to in this Proxy Statement. If other matters are properly presented at the meeting or any adjournment or postponement thereof for consideration, and you are a shareholder of record and have submitted a proxy card, the persons named in your proxy card will have the discretion to vote on those matters for you.

Why did I receive a notice in the mail regarding the Internet availability of proxy materials instead of a paper copy of proxy materials?

The rules of the Securities and Exchange Commission (the “SEC”) permit us to furnish proxy materials, including this Proxy Statement and the Annual Report, to our shareholders by providing access to such documents on the Internet instead of mailing printed copies. Shareholders will not receive paper copies of the proxy materials unless they request them. Instead, the Notice Regarding the Availability of Proxy Materials (the “Notice and Access Card”) provides instructions on how to access and review on the Internet all of the proxy materials. The Notice and Access Card also instructs you as to how to authorize via the Internet or telephone your proxy to vote your shares according to your voting instructions. If you would like to receive a paper or email copy of our proxy materials, you should follow the instructions for requesting such materials described in the Notice and Access Card.

1

Table of Contents

What does it mean if I receive more than one Notice and Access Card or more than one set of proxy materials?

It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each set of proxy materials, please submit your proxy by phone, via the Internet, or, if you received printed copies of the proxy materials, by signing, dating and returning the enclosed proxy card in the enclosed envelope.

Can I vote my shares by filling out and returning the Notice and Access Card?

No. The Notice and Access Card identifies the items to be voted on at the Annual Meeting, but you cannot vote by marking the Notice and Access Card and returning it. If you would like a paper proxy card, you should follow the instructions in the Notice and Access Card. The paper proxy card you receive will also provide instructions as to how to authorize via the Internet or telephone your proxy to vote your shares according to your voting instructions. Alternatively, you can mark the paper proxy card with how you would like your shares voted, sign the proxy card and return it in the envelope provided.

Who is entitled to vote at the Annual Meeting?

Holders of record of our ordinary shares as at the close of business on April 12, 2023 (the “Record Date”) will be entitled to receive notice of, attend and vote at the Annual Meeting and any continuation, postponement or adjournment thereof. At the close of business on the Record Date, there were 48,726,401 of our ordinary shares issued and outstanding and entitled to vote. On the basis that voting at the Annual Meeting will be conducted by way of a poll, every shareholder present in person, or by remote communication, or by proxy shall have one vote for each ordinary share held on any matter presented to shareholders at the Annual Meeting.

What is the difference between being a “record holder” and holding shares in “street name”?

A record holder (also called a “registered holder”) holds shares in his or her name. Shares held in “street name” means that shares are held in the name of a bank, broker or other nominee on the holder’s behalf.

What do I do if my shares are held in “street name”?

If your shares are held in a brokerage account or by a bank or other holder of record, you are considered the “beneficial owner” of shares held in “street name.” The Notice and Access Card or the proxy materials, if you have elected to receive a hard copy, have been forwarded to you by your broker, bank or other nominee who is considered, with respect to those shares, the shareholder of record. As the beneficial owner, you have the right to direct your broker, bank or other holder of record on how to vote your shares by following their instructions for voting. Please refer to information from your bank, broker or other nominee on how to submit your voting instructions.

How many shareholders must be present to hold the Annual Meeting in order for there to be a quorum?

A quorum must be present at the Annual Meeting in order for any business to be transacted. One or more shareholders holding at least one third of the voting share capital of the Company present in person, by remote communication, or by proxy and entitled to vote at that meeting shall form a quorum. If you sign and return your paper proxy card or authorize a proxy to vote electronically or telephonically, your shares will be counted to determine whether we have a quorum even if you abstain or fail to vote as indicated in the proxy materials.

Broker non-votes will also be considered present for the purpose of determining whether there is a quorum for the Annual Meeting.

Table of Contents

What are “broker non-votes”?

A “broker non-vote” occurs when shares held by a broker in “street name” for a beneficial owner are not voted with respect to a proposal because (1) the broker has not received voting instructions from the shareholder who beneficially owns the shares and (2) the broker lacks the authority to vote the shares at their discretion.

Under current stock exchange interpretations that govern broker non-votes, Proposal No. 1 for the election of directors is considered a non-discretionary matter, and a broker will lack the authority to vote uninstructed shares at their discretion on this proposal. Proposal No. 2 for the ratification, by ordinary resolution, of the appointment of Ernst & Young LLP as our independent registered public accounting firm is considered a discretionary matter, and a broker will be permitted to exercise its discretion to vote uninstructed shares on such proposal.

What if a quorum is not present at the Annual Meeting?

Under our Amended and Restated Articles of Association, no business shall be transacted at the Annual Meeting unless a quorum of shareholders is present in person, by remote communication or by proxy at the time when the meeting proceeds to business. If a quorum is not present in person, by remote communication or by proxy within half an hour of the scheduled time of the Annual Meeting, the Annual Meeting shall stand adjourned to the same day in the next week, at the same time and place. If a quorum is not present or represented within half an hour of the scheduled time for the adjourned Annual Meeting the shareholders present and entitled to vote at the adjourned Annual Meeting, present in person, by remote communication or by proxy, shall form a quorum.

How do I vote my shares and what are the voting deadlines?

If you are a shareholder of record, there are four ways to vote on the proposals:

Telephone and Internet voting facilities for shareholders of record will be available 24 hours a day and will close at 11:59 p.m., Eastern Time, on June 7, 2023.

If your shares are held in the name of a bank, broker or other holder of record, you will receive instructions on how to vote from the bank, broker or holder of record. You must follow the instructions of such bank, broker or holder of record in order for your shares to be voted.

How can I attend and vote at the Annual Meeting?

Shareholders as of the close of business on April 12, 2023, the Record Date, are entitled to participate in the Annual Meeting by visiting www.virtualshareholdermeeting.com/MGTX2023 and entering the 16-digit control number found on the proxy card or Notice Regarding the Availability of Proxy Materials previously received by shareholders. Shareholders may vote and ask questions during the Annual Meeting by following the instructions available on the

meeting website. Guests and shareholders without their 16-digit control number may join the Annual Meeting in a listen-only mode, but they will not have the option to vote shares or ask questions during the meeting.

Even if you plan to attend the Annual Meeting, we encourage you to vote your shares by proxy. You may still vote your shares at the meeting even if you have previously voted by proxy.

Will there be a question and answer session during the Annual Meeting?

We intend to answer appropriate questions submitted during the Annual Meeting and that are pertinent to the Company and the meeting matters. The Company will endeavor to answer as many questions submitted by stockholders as time permits. Only shareholders that have accessed the Annual Meeting as a shareholder (rather than a guest) by following the procedures outlined above in “How can I attend and vote at the Annual Meeting?” will be permitted to submit questions during the Annual Meeting. Each shareholder is limited to no more than two questions. Questions should be succinct and only cover a single topic. Questions from multiple shareholders on the same topic or that are otherwise related will be grouped, summarized and answered together. We will not address questions that are, among other things:

Additional information regarding the question and answer session will be provided in the “Rules of Conduct” available on the Annual Meeting webpage for shareholders that have accessed the Annual Meeting as a shareholder (rather than a guest) by following the procedures outlined above in “How can I attend and vote at the Annual Meeting?”.

Who will count the votes?

Representatives of Broadridge Investor Communications Services (“Broadridge”) will tabulate the votes, and a representative of Broadridge will act as inspector of election.

If you hold shares in street name, you may submit new voting instructions by contacting your bank, broker or other nominee. You may also change your vote or revoke your proxy at the Annual Meeting if you obtain a signed proxy from the record holder (broker, bank or other nominee) giving you the right to vote the shares.

Your most recent proxy card or telephone or Internet proxy is the one that is counted. Your attendance at the Annual Meeting by itself will not revoke your proxy unless you give written notice of revocation to the Company before your proxy is voted or you vote at the Annual Meeting via the webcast.

Who will pay for the cost of this proxy solicitation?

The accompanying proxy is solicited by and on behalf of our Board, whose Notice of Annual General Meeting of Shareholders is attached to this proxy statement, and we will pay the cost of soliciting proxies. Proxies may be solicited on our behalf by directors, officers or employees (for no additional compensation) in person or by telephone, electronic transmission and facsimile transmission. Brokers and other nominees will be requested to solicit proxies or authorizations from beneficial owners and will be reimbursed for their reasonable expenses.

PROPOSAL NO. 1 ELECTION OF DIRECTORS

Board Size and Structure

In accordance with our Amended and Restated Memorandum and Articles of Association as currently in effect (the “Articles”), the Board has the discretion to fix the minimum and maximum number of directors to serve on our Board and, unless such numbers are fixed, the minimum shall be one and the maximum shall be unlimited. Our Board has not set a maximum, and the Board currently consists of eight directors.

Our Articles provide that the Board be divided into three classes, Class I, Class II and Class III, with staggered, three-year terms. At each annual general meeting of shareholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual general meeting following election. Each director shall hold office until the expiration of their term, until their successor shall have been duly elected and qualified or until their earlier death, resignation or removal. Generally, vacancies or newly created directorships on the Board will be filled by vote of a majority of the directors then in office. A director appointed by the Board to fill a vacancy will hold office until the next election of the class for which such director was chosen, subject to the election and qualification of his or her successor and his or her earlier death, resignation or removal.

Current Directors and Terms

Our current directors and their respective classes and terms are set forth below.

​

Nominees for Director

Ms. Seligman and Drs. Hukkelhoven and Yu have been nominated by the Board to stand for election. As Ms. Seligman and Drs. Hukkelhoven and Yu are directors assigned to Class II, their current term of service will expire at the Annual Meeting. If elected by the shareholders at the Annual Meeting, Ms. Seligman and Drs. Hukkelhoven and Yu will each serve for a term expiring at our annual general meeting of shareholders to be held in 2026 (the “2026 Annual Meeting”) and until the election and qualification of her successor or until her earlier death, resignation or removal.

Each person nominated for election has agreed to serve if elected, and we have no reason to believe that any nominee will be unable to serve. If, however, prior to the Annual Meeting, the Board of Directors should learn that any nominee will be unable to serve for any reason, the proxies that otherwise would have been voted for this nominee will be voted for a substitute nominee as selected by the Board. Alternatively, the proxies, at the Board’s discretion, may be voted for a fewer number of nominees that results from the inability of any nominee to serve.

Information About Board Nominees and Continuing Directors

The following pages contain certain biographical information as of April 12, 2023 for each nominee for director and each director whose term as a director will continue after the Annual Meeting, including all positions he or she holds, his or her principal occupation and business experience for the past five years, and the names of other publicly-held companies of which the director or nominee currently serves as a director or has served as a director during the past five years.

We believe that all of our directors and nominees display: personal and professional integrity; satisfactory levels of education and/or business experience; broad-based business acumen; an appropriate level of understanding of our business and its industry and other industries relevant to our business; the ability and willingness to devote adequate

In this regard, the Audit Committee evaluates the qualifications, performance and independence of our independent registered public accounting firm and determines whether to re-engage our current firm. As part of its evaluation, the Audit Committee considers, among other factors, the quality and efficiency of the services provided by the firm, including the performance, technical expertise, industry knowledge and experience of the lead audit partner and the audit team assigned to our account; the overall strength and reputation of the firm; the firm’s global capabilities relative to our business; and the firm’s knowledge of our operations. Ernst & Young LLP has served as our independent registered public accounting firm since 2016. Neither the accounting firm nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors and providing audit and permissible non-audit related services. Upon consideration of these and other factors, the Audit Committee has appointed Ernst & Young LLP to serve as our independent registered public accounting firm for the year ending December 31, 2023.

Although ratification is not required by our Articles or otherwise, the Board is submitting the selection of Ernst & Young LLP to our shareholders for ratification because we value our shareholders’ views on the Company’s independent registered public accounting firm and it is a good corporate governance practice. If our shareholders do not ratify the selection, the Audit Committee and the Board of Directors will reconsider such appointment. Even if the selection is ratified, the Audit Committee, in its discretion, may select a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and its shareholders.

Representatives of Ernst & Young LLP are expected to attend the Annual Meeting and to have an opportunity to make a statement as they may desire and be available to respond to appropriate questions from shareholders.

The table below sets forth the aggregate fees billed to MeiraGTx for services related to the fiscal years ended December 31, 2022 and 2021, by Ernst & Young LLP, our independent registered public accounting firm.

Pre-Approval Policies and Procedures

The formal written charter for our Audit Committee requires that the Audit Committee, or the chairman of the Audit Committee, pre-approve all audit services to be provided to us, whether provided by our principal auditor or other firms, and all other services (review, attest and non-audit) to be provided to us by our independent registered public

Table of Contents

accounting firm in accordance with the Company’s audit services pre-approval policy (as amended from time to time), other than de minimis non-audit services approved in accordance with applicable SEC rules.

The Audit Committee has adopted a pre-approval policy that sets forth the procedures and conditions pursuant to which audit and non-audit services proposed to be performed by our independent registered public accounting firm may be pre-approved. This pre-approval policy generally provides that the Audit Committee will not engage an independent registered public accounting firm to render any audit, audit-related, tax or permissible non-audit service unless the service is either (i) explicitly approved by the Audit Committee or (ii) entered into pursuant to the pre-approval policies and procedures described in the pre-approval policy. Unless a type of service to be provided by our independent registered public accounting firm has received this latter general pre-approval under the pre-approval policy, it requires specific pre-approval by the Audit Committee.

On an annual basis, the Audit Committee reviews and generally pre-approves the services (and related fee levels or budgeted amounts) that may be provided by the Company’s independent registered public accounting firm without first obtaining specific pre-approval from the Audit Committee. The Audit Committee may revise the list of general pre-approved services from time to time, based on subsequent determinations. Any member of the Audit Committee to whom the Committee delegates authority to make pre-approval decisions must report any such pre-approval decisions to the Audit Committee at its next scheduled meeting. If circumstances arise where it becomes necessary to engage the independent registered public accounting firm for additional services not contemplated in the original pre-approval categories or above the pre-approved amounts, the Audit Committee requires pre-approval for such additional services or such additional amounts.

The services provided to us by Ernst & Young LLP in 2021 and 2022 were provided in accordance with our pre-approval policies and procedures, as applicable.

Board Recommendation

The Board of Directors unanimously recommends a vote FOR the ratification, by ordinary resolution, of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023.

Audit Committee Report

The Audit Committee operates pursuant to a charter which is reviewed annually by the Audit Committee. Additionally, a brief description of the primary responsibilities of the Audit Committee is included in this Proxy Statement under the discussion of “Corporate Governance—Audit Committee.” Under the Audit Committee charter, management is responsible for the preparation, presentation and integrity of the Company’s financial statements, the application of accounting and financial reporting principles and our internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. The independent registered public accounting firm is responsible for auditing our financial statements and expressing an opinion as to their conformity with accounting principles generally accepted in the United States.

In the performance of its oversight function, the Audit Committee reviewed and discussed with management and Ernst & Young LLP, as the Company’s independent registered public accounting firm, the Company’s audited financial statements for the fiscal year ended December 31, 2022. The Audit Committee also discussed with the Company’s independent registered public accounting firm the matters required to be discussed by applicable requirements of the Public Company Accounting Oversight Board (the “PCAOB”) and the Securities and Exchange Commission. In addition, the Audit Committee received and reviewed the written disclosures and the letters from the Company’s independent registered public accounting firm required by applicable requirements of the PCAOB, regarding such independent registered public accounting firm’s communications with the Audit Committee concerning independence, and discussed with the Company’s independent registered public accounting firm their independence from the Company.

Based upon the review and discussions described in the preceding paragraph, the Audit Committee recommended to the Board that the Company’s audited financial statements be included in its Annual Report on Form 10‑K for the fiscal year ended December 31, 2022 filed with the SEC.

CORPORATE GOVERNANCE

Corporate Governance Guidelines

Our Board of Directors has adopted Corporate Governance Guidelines that govern its operation and that of its Committees. Our Board annually reviews our Corporate Governance Guidelines and, from time to time, our Board will revise them in response to changing regulatory requirements, evolving best practices and the concerns of our shareholders and other constituents. A copy of these Corporate Governance Guidelines can be found in the “Corporate Governance—Documents & Charters” section of the “Investors & Media” page of our website located at https://meiragtx.com/, or by writing to our Secretary at our offices at 450 East 29^th Street, 14^th Floor, New York, New York 10016.

Board Leadership Structure

Our Corporate Governance Guidelines provide our Board of Directors with flexibility to combine or separate the positions of Chairman of the Board and Chief Executive Officer in accordance with its determination that utilizing one or the other structure would be in the best interests of the Company and its shareholders. If the Chairman of the Board is a member of management or does not otherwise qualify as independent, our Corporate Governance Guidelines provide for the appointment by the independent directors of a lead independent director (the “Lead Director”). The Lead Director’s responsibilities include, but are not limited to: presiding over all meetings of the Board at which the Chairman of the Board is not present, including any executive sessions of the independent directors; approving Board meeting schedules and agendas; and acting as the liaison between the independent directors and the Chief Executive Officer and Chairman of the Board. Our Corporate Governance Guidelines provide that, at such times as the Chairman of the Board qualifies as independent, the Chairman of the Board will carry out the duties of the Lead Director, as applicable.

The positions of our Chairman of the Board and our Chief Executive Officer and President are currently served by two separate persons. Dr. Harris, an independent director on our Board, serves as Chairman of the Board, and Dr. Forbes serves as our Chief Executive Officer and President. In his capacity as the independent Board Chairman, Dr. Harris performs the functions of the Lead Director.

The Board believes our current leadership structure of Chief Executive Officer and Chairman of the Board being held by two separate individuals is in the best interests of the Company and its shareholders and strikes the appropriate balance between the Chief Executive Officer and President’s responsibility for the strategic direction, day-to-day leadership and performance of our Company and the Chairman of the Board’s responsibility to guide overall strategic direction of our Company, to provide oversight of our corporate governance and guidance to our Chief Executive Officer and President and to set the agenda for and preside over Board meetings. We recognize that different leadership structures may be appropriate for companies in different situations and believe that no one structure is suitable for all companies. Accordingly, the Board will continue to periodically review our leadership structure and make such changes in the future as it deems appropriate and in the best interests of the Company and its shareholders.

Director Independence

Under our Corporate Governance Guidelines and the Nasdaq rules, a majority of our directors must qualify as independent directors and a director is not independent unless the Board affirmatively determines that he or she does not have a direct or indirect material relationship with us or any of our subsidiaries. In addition, the director must meet the bright-line tests for independence set forth by the Nasdaq rules.

Our Board has undertaken a review of its composition, the composition of its Committees and the independence of our directors and considered whether any 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. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family

15

Table of Contents

relationships, our Board of Directors has determined that none of Keith R. Harris, Ph.D., Martin Indyk, Ph.D., Lord Mendoza, Nicole Seligman, Thomas E. Shenk, Ph.D. and Debra Yu, M.D., representing six of our eight directors, has 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 qualifies as “independent” as that term is defined under the Nasdaq rules. In addition, our former directors Joel S. Marcus and Arnold J. Levine, Ph.D. were determined to be independent while they served on our Board of Directors. Ellen Hukkelhoven, Ph.D. was determined not to be independent. In making these determination, our Board of Directors considered the relationships that each non-employee director has with us and all other facts and circumstances our Board of Directors deemed relevant in determining their independence, including the director’s beneficial ownership of our ordinary shares and the relationships of our non-employee directors with certain of our significant shareholders. In determining that Dr. Hukkelhoven was not independent, the Board considered the Company’s relationships with Perceptive Advisors, where Dr. Hukkelhoven serves as the Head of Biotechnology Investments, including that Perceptive Advisors owns, in the aggregate, more than 10% of the Company’s outstanding shares and that in August 2022 we borrowed $75 million from Perceptive Credit Holdings III, LP (“Perceptive Credit Holdings”), an affiliate of Perceptive Advisors, as described in more detail below under “Certain Transactions with Related Persons—Debt Financing.” Alexandria Forbes, Ph.D. is not considered an independent director because she is currently employed by the Company as our President and Chief Executive Officer.

Board and Board Committee Meetings and Attendance

During 2022, our Board of Directors met nine times and acted by written consent nine times, the Audit Committee met five times and acted by written consent four times, the Compensation Committee met two times and acted by written consent three times, the Nominating and Corporate Governance Committee met two times and acted by written consent three times, and the Science and Technology Committee did not meet in 2022. In 2022, each of our directors attended at least 75% of the meetings of the Board and committees on which such director served as a member.

Executive Sessions

Executive sessions, which are meetings of the non-management or independent members of the Board, are regularly scheduled throughout the year. Our chairman of the Board, Dr. Harris, presided over such executive sessions in 2022.

Director Attendance at the Annual Meeting of Shareholders

We do not have a formal policy regarding the attendance of our Board members at our annual general meetings of shareholders, but we expect all directors to make every effort to attend any meeting of shareholders. All of the members of the Board of Directors attended the 2022 annual general meeting of shareholders except Drs. Levine and Shenk due to previously scheduled commitments.

Board Committees

Our Board of Directors has four standing committees: an Audit Committee, a Compensation Committee, a Nominating and Corporate Governance Committee and a Science and Technology Committee, each of which has the composition and the responsibilities described below. In addition, from time to time, special committees may be established under the direction of our Board when necessary to address specific issues. Each of the Audit Committee, the

Audit Committee

Our Audit Committee is responsible for, among other things:

17

Table of Contents

Our Board of Directors has affirmatively determined that each member of our Audit Committee (i) qualifies as “independent” under Nasdaq’s heightened standards and Rule 10A-3 of the Exchange Act of 1934, as amended (the “Exchange Act”), applicable to audit committee members, and (ii) meets the requirements for financial literacy under the applicable Nasdaq rules and regulations. Our Board has also affirmatively determined that Keith R. Harris, Ph.D. qualifies as an “audit committee financial expert,” as such term is defined in Item 407(d)(5) of Regulation S-K.

Compensation Committee

Our Compensation Committee is responsible for, among other things:

Our Board of Directors has determined that each member of our Compensation Committee (i) qualifies as “independent” under Nasdaq’s heightened standards applicable to compensation committee members and (ii) is a “non-employee director” as defined in Section 16b-3 of the Exchange Act.

The Compensation Committee has the authority to retain or obtain the advice of compensation consultants, legal counsel and other advisors to assist in carrying out its responsibilities. Before selecting any such consultant, counsel or advisor, the Compensation Committee reviews and considers the independence of such consultant, counsel or advisor in accordance with applicable Nasdaq rules. We must provide appropriate funding for payment of reasonable compensation to any advisor retained by the Compensation Committee.

Compensation Consultants

In accordance with its authority to retain consultants and advisors described above, the Compensation Committee has engaged the services of Total Compensation Solutions (“TCS”) on an annual basis as its compensation consultant to provide advice, consulting and guidance on executive, non-employee director and employee retention and incentive plans.

All services related to executive and director compensation provided by TCS during 2022 were conducted under the direction or authority of the Compensation Committee, and all work performed by TCS was pre-approved by the Compensation Committee. Neither TCS nor any of its affiliates maintains any other direct or indirect business relationships with us or any of our subsidiaries. Additionally, during 2022, TCS did not provide any services to us unrelated to executive and director compensation.

The Compensation Committee evaluated whether any work provided by TCS raised any conflict of interest for services performed during 2022 and determined that it did not.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee is responsible for, among other things:

Our Board has determined that each member of our Nominating and Corporate Governance Committee qualifies as “independent” under Nasdaq rules applicable to nominating and corporate governance committee members.

Science and Technology Committee

Our Science and Technology Committee is responsible for, among other things:

Director Nominations Process

The Nominating and Corporate Governance Committee is responsible for recommending candidates to serve on the Board and its Committees. In considering whether to recommend any particular candidate to serve on the Board or its Committees or for inclusion in the Board’s slate of recommended director nominees for election at the annual general meeting of shareholders, the Nominating and Corporate Governance Committee considers the criteria set forth in our Corporate Governance Guidelines. Specifically, the Nominating and Corporate Governance Committee may take into account many factors, including without limitation: personal and professional integrity, ethics and values; experience in corporate management, such as serving as an officer or former officer of a publicly held company; strong finance experience; relevant social policy concerns; experience relevant to the Company’s industry; experience as a board member or executive officer of another publicly held company; relevant academic expertise or other proficiency in an area of the Company’s operations; diversity of expertise and experience in substantive matters pertaining to the Company’s business relative to other Board members; diversity of background and perspective, including, but not limited to, with respect to age, gender, gender identification, self-identifying as female, as an underrepresented minority

19

Table of Contents

or as LGBTQ+, race, ethnicity, place of residence and specialized experience; practical and mature business judgment, including, but not limited to, the ability to make independent analytical inquiries; and any other relevant qualifications, attributes or skills. In determining whether to recommend a director for re-election, the Nominating and Corporate Governance Committee may also consider the director’s past attendance at meetings and participation in and contributions to the activities of the Board.

We consider diversity, such as race, ethnicity, gender and membership in an underrepresented community, as part of the criteria with regard to identifying director nominees, but do not have a formal diversity policy. Such characteristics were considered in connection with the appointment of Debra Yu, M.D. to our Board. The Board evaluates each individual in the context of the Board as a whole, with the objective of assembling a group that can best perpetuate the success of the business and represent shareholder interests through the exercise of sound judgment using its diversity of experience in these various areas.

In identifying prospective director candidates, the Nominating and Corporate Governance Committee may seek referrals from other members of the Board, management, shareholders and other sources, including third party recommendations. The Nominating and Corporate Governance Committee also may, but need not, retain a search firm in order to assist it in identifying candidates to serve as directors of the Company. The Nominating and Corporate Governance Committee uses the same criteria for evaluating candidates regardless of the source of the referral or recommendation. When considering director candidates, the Nominating and Corporate Governance Committee seeks individuals with backgrounds and qualities that, when combined with those of our incumbent directors, provide a blend of skills and experience to further enhance the Board’s effectiveness. In connection with its annual recommendation of a slate of nominees, the Nominating and Corporate Governance Committee also may assess the contributions of those directors recommended for re-election in the context of the Board evaluation process and other perceived needs of the Board. Debra Yu, M.D., one of our Class II director nominees, was recommended as a potential candidate for election to our Board by the Company’s senior management and the Company’s largest shareholder, Perceptive Advisors.

Each of the Class II director nominees to be elected at the Annual Meeting was evaluated in accordance with our standard review process for director candidates in connection with their initial appointment and their nomination for re-election at the Annual Meeting.

When considering whether the directors and nominees have the experience, qualifications, attributes and skills, taken as a whole, to enable the Board to satisfy its oversight responsibilities effectively in light of our business and structure, the Board focused primarily on the information discussed in each Board member’s biographical information set forth above. We believe that our directors provide an appropriate mix of experience and skills relevant to the size and nature of our business. This process resulted in the Board’s nomination of the incumbent directors named in this Proxy Statement and proposed for election by our shareholders at the Annual Meeting.

The Nominating and Corporate Governance Committee will consider director candidates recommended by shareholders, and such candidates will be considered and evaluated under the same criteria described above. Any recommendation submitted to the Company should be in writing and should include any supporting material the shareholder considers appropriate in support of that recommendation, but must include information that would be required under the rules of the SEC to be included in a proxy statement soliciting proxies for the election of such candidate and a written consent of the candidate to serve as one of our directors if elected. Shareholders wishing to propose a candidate for consideration may do so by submitting the above information to the attention of our Secretary, MeiraGTx Holdings plc, 450 East 29^th Street, 14^th Floor, New York, New York 10016. All recommendations for nominations received by our Secretary that satisfy the requirements under the rules of the SEC relating to such director nominations will be presented to the Nominating and Corporate Governance Committee for its consideration. For additional information, regarding shareholder proposals, see “Shareholder Proposals and Director Nominations.”

Board Diversity

Our Board of Directors values the diversity of its members. As noted above, our Board of Directors considers diversity, including gender and ethnic diversity, as adding to the overall mix of perspectives of our Board of Directors as a whole. With the assistance of the Nominating and Corporate Governance Committee, our Board of Directors regularly

Table of Contents

reviews trends in board composition, including on director diversity. The following table provides certain information about the composition and diversity of our Board as required under Nasdaq listing standards.

​

Board Role in Risk Oversight

The Board of Directors has overall responsibility for risk oversight, including, as part of regular Board and Committee meetings, general oversight of executives’ management of risks relevant to the Company. A fundamental part of risk oversight is not only understanding the material risks a company faces and the steps management is taking to manage those risks, but also understanding what level of risk is appropriate for the Company. The involvement of the Board of Directors in reviewing our business strategy is an integral aspect of the Board’s assessment of management’s tolerance for risk and its determination of what constitutes an appropriate level of risk for the Company. While the full Board has overall responsibility for risk oversight, it is supported in this function by its Audit Committee, Compensation Committee, Nominating and Corporate Governance Committee and Science and Technology Committee. Each of the Committees regularly reports to the Board.

The Audit Committee assists the Board in fulfilling its risk oversight responsibilities by periodically reviewing our accounting, reporting and financial practices, including the integrity of our financial statements, the surveillance of administrative and financial controls, our compliance with legal and regulatory requirements and our enterprise risk management program. The Audit Committee also oversees financial risks and information security risks (including cybersecurity and data protection). Through its regular meetings with management, including the finance, legal, compliance, risk, internal control and information technology functions, the Audit Committee reviews and discusses significant areas of our business and summarizes for the Board areas of risk and the appropriate mitigating factors. The Compensation Committee assists the Board by overseeing and evaluating risks related to the Company’s compensation structure and compensation programs, including the formulation, administration and regulatory compliance with respect to compensation matters. The Nominating and Corporate Governance Committee assists the Board by overseeing and evaluating programs and risks associated with Board organization, membership and structure, independence, potential conflicts of interest and corporate governance, as well as risks relating to our non-financial compliance programs. The Science and Technology Committee reviews our pipeline to evaluate our progress in achieving our long-term strategic research and development goals and objectives and assure that we make well-informed choices in investment in research and development and technology. In addition, our Board receives periodic detailed operating performance reviews from management.

Committee Charters and Corporate Governance Guidelines

We intend to make any necessary disclosures regarding amendments to, or waivers from, provisions of our Code of Conduct that applies to any of our directors and executive officers on our website rather than by filing a Current Report on Form 8-K.

Anti-Hedging Policy

Our Board of Directors has adopted an Insider Trading Compliance Policy, which applies to all of our directors, officers and employees. The policy prohibits our directors, officers and employees from engaging in hedging or monetization transactions, such as zero-cost collars and forward sale contracts; short sales; and transactions in publicly traded options, such as puts, calls and other derivatives involving our equity securities.

Communications with the Board

Any shareholder or any other interested party who desires to communicate with our Board of Directors, our non-management directors or any specified individual director, including our chairman, may do so by directing such correspondence to the attention of our Secretary, MeiraGTx Holdings plc, 450 East 29^th Street, 14^th Floor, New York, New York 10016. Our Secretary will forward the communication to the appropriate director or directors as appropriate. Any complaints or concerns relating to our accounting, internal accounting controls or auditing matters will be referred to the chairman of the Audit Committee. Other concerns will be referred to the chairman of the Board with a copy to the chairman of the Nominating and Corporate Governance Committee. Any complaints or concerns may be reported anonymously or confidentially. We strictly prohibit any retaliation for reporting a possible violation of law, ethics, or firm policy regardless of whom the report concerns.

EXECUTIVE COMPENSATION

Overview

This section discusses the material components of the executive compensation program for our executive officers who are named in the “2022 Summary Compensation Table” below. In 2022, our “named executive officers” and their positions were as follows:

We had a successful year operationally in 2022 as we continued to make important progress in a number of key areas, including clinical development, manufacturing, research and raising additional capital. The executive team remains focused on building a vertically integrated company with several valuable and unique sets of assets, which include: our therapeutic pipeline, leading manufacturing capabilities, clinical and quality infrastructure, extensive vector engineering capabilities and technology platforms led by our transformative riboswitch gene regulation technology. In particular, our 2022 performance was attributable to a number of factors, including:

The Company believes these strong results were largely driven by the leadership of our named executive officers. Despite our strong operational performance during 2022, the Company’s share price was negatively impacted by the difficulties facing publicly traded biotech companies during the year and a challenging global macroeconomic environment. In making its compensation decisions based on 2022 performance, the Compensation Committee considered these factors and approved annual cash bonuses for each of our named executive officers that were at least 30% less than the actual cash bouses earned by the named executive officers for the prior year. Similarly, the equity compensation awards granted to our named executive officers in February 2023 had a grant date fair value between 35% and 55% lower than the grant date fair value of the equity awards granted to these executives in 2022.

2022 Summary Compensation Table

Narrative to Summary Compensation Table

Base Salaries

The named executive officers receive a base salary to compensate them for services rendered to our Company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities. The base salaries of Dr. Forbes and Mr. Giroux were set at $580,000 and $495,000, respectively, in connection with our attaining a second fundraising milestone in March 2018. No changes were made to the base salaries of Dr. Forbes or Mr. Giroux during 2022.

Dr. Naylor’s annual base salary of £330,000 was set in January 2020. Under his employment agreement, Dr. Naylor is eligible to receive a pension contribution to a defined contribution pension scheme equal to 10% of his salary. For 2022, Dr. Naylor elected not to participate in the pension scheme and instead received the £33,000 as additional base salary during the year.

Bonuses

Dr. Forbes and Mr. Giroux are entitled to guaranteed annual cash bonus payments and may receive performance-based bonuses pursuant to the terms of their employment agreements, as described in more detail below under “Executive Compensation Arrangements—Dr. Forbes and Mr. Giroux.” In February 2023, the Compensation Committee assessed Company performance during 2022 based on our achievement of a number of clinical, regulatory and corporate milestones during the year as described above, as well as the negative impact to the Company’s share

price during the year, and determined that the guaranteed and performance based bonus amounts payable to Dr. Forbes and Mr. Giroux for 2022 would be $1,715,000 and $1,316,000, respectively.

Pursuant to his employment agreement, Dr. Naylor has the opportunity to earn an annual discretionary bonus. In February 2023, the Compensation Committee determined to pay Dr. Naylor a bonus for 2022 performance of $560,000 based on an assessment of the Company’s achievements and results described above.

Pursuant to our 2018 Incentive Award Plan, referred to as the 2018 Plan, we may grant cash and equity incentives to directors, employees (including our named executive officers) and consultants of our Company and certain of its affiliates to enable our Company and certain of its affiliates to obtain and retain services of these individuals, which is essential to our long-term success.

The SEC’s compensation disclosure rules currently require disclosure of the grant date value of equity awards granted during the last year (2022 in this case). Accordingly, the 2022 Summary Compensation Table and the Outstanding Equity Awards at Fiscal Year-End Table show the equity awards granted during the 2022 calendar year in respect of 2021 performance (instead of the equity awards for 2022 performance granted in February 2023). In light of the SEC’s current compensation disclosure rules, we have provided the following supplemental table which sets forth the restricted share unit and option awards granted to Drs. Forbes and Naylor and Mr. Giroux by the Compensation Committee in February 2023 for 2022 performance. For the restricted share unit awards, 50% of the award vests on the second anniversary of the grant date and 25% of the award vests on each of the third and fourth anniversaries of the grant date. For the option awards, 25% of the shares subject to the option vest on the first anniversary of the grant date and the remainder of the shares subject to the option vest in 36 substantially equal monthly installments thereafter.

For 2022 performance, the Compensation Committee elected to continue granting restricted share unit awards with the initial vesting and payout beginning on the second anniversary of the grant date to provide long-term motivation for our executives to create shareholder value and to promote greater retention of our executives. The Committee also awarded options for 2022 performance to provide strong performance incentives aligned with shareholder interests since the option awards will only have value if the Company’s share price increases.

Pursuant to their employment agreements, Dr. Forbes and Mr. Giroux are entitled to annual grants of restricted ordinary shares. The number of restricted shares subject to each such award is determined by the Compensation Committee, with input from our Chief Executive Officer with respect to the grant to Mr. Giroux. For 2022, the Compensation Committee, with input from the Chief Executive Officer with respect to Mr. Giroux, determined not to make any such grants.

Other Elements of Compensation

Retirement Plans

Our named executive officers, other than Dr. Naylor, are eligible to participate in our 401(k) plan in the United States on the same terms as other full-time employees. We match 100% of employee contributions to our 401(k) plan, up to 6% of eligible compensation. Dr. Naylor, who is employed in the United Kingdom, is eligible to receive a pension contribution to a defined contribution pension scheme equal to 10% of his base salary. For 2022, Dr. Naylor elected not to participate in the pension scheme and therefore did not receive the pension contribution from us this year. Instead, he received this amount in base salary. We believe that providing a vehicle for tax-deferred retirement savings adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our named executive officers, in accordance with our compensation policies.

Employee Benefits

All of our full-time employees, including our named executive officers, are eligible to participate in our health and welfare plans, subject to the same terms and eligibility requirements.

Outstanding Equity Awards at Fiscal Year-End

The following table summarizes the number of ordinary shares underlying outstanding equity incentive plan awards for each named executive officer as of December 31, 2022.

Executive Compensation Arrangements

We have entered into employment agreements with each of our named executive officers. Certain key terms of these agreements are described below.

Dr. Forbes and Mr. Giroux

We entered into employment agreements with Dr. Forbes and Mr. Giroux in February 2016. The agreements have an initial term of three years and automatically renew for successive one-year periods unless notice of non-renewal is provided by either party at least 90 days prior to the expiration of the then-current term.

Pursuant to the employment agreements, Dr. Forbes and Mr. Giroux are entitled to annual base salaries, annual cash bonuses equal to 100% of their respective base salaries, referred to as the guaranteed bonus, and the opportunity to earn annual performance-based bonuses targeted at 60% of base salary for Dr. Forbes and 50% of base salary for Mr. Giroux, referred to as the performance bonus.

In the event we complete a strategic collaboration resulting in upfront payments to us, each of Dr. Forbes and Mr. Giroux is entitled to a cash bonus in an amount determined by the Compensation Committee and, with respect to Mr. Giroux, the Chief Executive Officer, provided that such bonus will not be less than 1% of the upfront payments received by us in such collaboration. There is no limit on the number of bonuses the executives may receive per year pursuant to this arrangement.

In the event either of Dr. Forbes’ or Mr. Giroux’s employment is terminated due to death or disability, or Dr. Forbes or Mr. Giroux resigns employment without good reason, which includes the executive’s election not to renew the term of the employment agreement, the executive (or the executive’s estate or beneficiary) is entitled to receive the executive’s base salary, guaranteed bonus, and performance bonus as if the executive’s employment had continued for an additional 12-month period.

In the event either of Dr. Forbes or Mr. Giroux is terminated by us for any reason other than cause, including due to a change in control, the Company elects not to renew the term of the employment agreement, or Dr. Forbes or Mr. Giroux resigns for good reason, the executive is entitled to (i) three months’ notice of termination or pay in lieu of notice, (ii) receive the executive’s base salary, guaranteed bonus, and performance bonus as if the executive’s employment had continued for an additional 24-month period (including a pro-rated guaranteed bonus and performance bonus for any stub periods), (iii) employee benefits and post-employment employee benefits and conversion rights in accordance with the terms and conditions of the plans, policies, programs, or perquisites in which the executive participates for a period of 24-months following the end of the then-current term, (iv) incentive and deferred

28

Table of Contents

compensation incentive rights in accordance with the terms and conditions of the incentive and deferred compensation plans in which the executive participates; provided, however, that the executive shall be deemed fully vested in any incentive and deferred compensation awards under such plans upon a termination, (v) accelerated vesting of any unvested restricted shares and equity incentive awards, (vi) to the extent not yet granted, be granted fully vested ordinary shares for any awards to which the executive may at the time be entitled as if all conditions applicable to such award were met, and (vii) be paid, within 30 days of termination, a cash termination fee equivalent to 1.50% for Dr. Forbes, or 1% for Mr. Giroux, of the average “market value” of our shares during the 90-trading day period prior to the termination plus payment of any taxes owed by the executive as a result of such termination fee. For purposes of the employment agreements, “market value” means the number obtained by multiplying (x) the aggregate number of shares of our voting and non-voting common equity (including shares held by employees and affiliates) by (y) the average of the last closing prices of our common equity in the principal market for such common equity, as adjusted on a pro-rata basis for any mechanical adjustments in our equity resulting from forward or reverse share splits.

For purposes of the employment agreements, “cause” means the executive’s (i) conviction of a felony involving moral turpitude, (ii) embezzlement, or (iii) intentional and willful misconduct that may subject us to criminal liability, which misconduct is not cured within 30 days after written notice to the executive of such conduct, if curable.

For purposes of the employment agreements, “good reason” means (i) any material diminution of the executive’s title, duties, work responsibilities, authority, or status, or the assignment of duties that would typically be performed by someone in the executive’s position to an individual other than the executive, (ii) a material negative change in the executive’s reporting structure, (iii) a change in control, (iv) a reduction in the executive’s then current base salary, (v) a change in the executive’s principal place of employment to a location more than 15 miles from Manhattan, New York, (vi) our breach of the employment agreement that is not cured within 30 days after receiving notice of such breach, (vii) our insistence that the executive perform or condone any illegal conduct, or (viii) a hostile or abusive work environment or harassment.

Dr. Naylor

We have entered into an employment agreement with Dr. Naylor, pursuant to which he serves as our Chief Development Officer. The agreement is for an unspecified term and may be terminated by either party upon no less than 12-months’ notice, or pay in lieu of notice. Pursuant to his employment agreement, Dr. Naylor is entitled to an annual base salary and has the opportunity to earn discretionary annual bonuses.

Dr. Naylor’s employment agreement contains certain restrictive covenants pursuant to which he has agreed to refrain from competing with us or soliciting certain of our clients, customers or employees, in each case, for a period of 12 months following his termination of employment.

Potential Payments Upon a Termination or a Change in Control

As described above in the section titled “Executive Compensation Arrangements—Dr. Forbes and Mr. Giroux,” Dr. Forbes and Mr. Giroux may become entitled to certain payments and benefits in connection with their termination or a change in control of our Company. Dr. Naylor may become entitled to certain payments in connection with his termination outside of a change in control of our Company as described above in the section titled “Executive Compensation Arrangements—Dr. Naylor.”

In addition to the employment agreement described above, the Company has entered into a change in control agreement with Dr. Naylor. The change in control agreement provides for the payment of benefits if Dr. Naylor’s employment is terminated within twelve months following a Change in Control (defined below), either by the Company not for Cause (defined below) (and not due to Dr. Naylor’s death or disability) or by Dr. Naylor for Good Reason (as defined below). In addition, if Dr. Naylor’s employment is terminated by the Company other than for Cause within two weeks prior to the date of a Change in Control and it is reasonably demonstrated that the termination arose in connection with, or in anticipation of, the Change in Control, the benefits set forth below will be paid to Dr. Naylor.

The benefits payable are (i) base salary through the date of executive’s termination and any other amounts or benefits, if any, under the Company’s employee benefit plans, programs or arrangements to which executive may be entitled pursuant to the terms of such plans, programs or arrangements or applicable law, (ii) any unpaid annual bonus earned by executive for the year prior to the year in which the qualifying termination occurs, and (iii) one (1) times the sum of the executive’s annual base salary and target bonus amount based, in each case, on the rate in effect prior to any decrease that would give the executive the right to resign for Good Reason.

Additionally, all of executive’s unvested equity or equity-based awards under any of the Company’s equity compensation plans that vest solely based upon executive’s continued employment or service shall immediately become 100% vested on the later of the date of executive’s qualifying termination and the Change in Control (with any such awards that vest in whole or in part based upon the attainment of performance vesting conditions being governed by the terms of the applicable award agreement) and, to the extent necessary, any unvested equity awards will remain outstanding and eligible to vest following executive’s qualifying termination if a Change in Control occurs within two (2) weeks following executive’s qualifying termination.

For purposes of the change in control agreement, “Change in Control” means and includes each of the following: (i) a transaction or series of transactions (other than an offering of our ordinary shares to the general public through a registration statement filed with the SEC or a transaction or series of transactions that meets the requirements of clauses (A) and (B) of subsection (iii) below) whereby any “person” or related “group” of “persons” (as such terms are used in Sections 13(d) and 14(d)(2) of the Exchange Act) (other than the Company, any of its subsidiaries, an employee benefit plan maintained by Company or any of its subsidiaries or a “person” that, prior to such transaction, directly or indirectly controls, is controlled by, or is under common control with, the Company) directly or indirectly acquires beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of securities of the Company possessing more than 50% of the total combined voting power of the Company’s securities outstanding immediately after such acquisition; (ii) during any period of two consecutive years, individuals who, at the beginning of such period, constitute the Board together with any new director(s) (other than a director designated by a person who shall have entered into an agreement with the Company to effect a transaction described in subsections (i) or (iii)) whose election by the Board or nomination for election by the Company’s shareholders was approved by a vote of at least two-thirds of the directors then still in office who either were directors at the beginning of the two-year period or whose election or nomination for election was previously so approved, cease for any reason to constitute a majority thereof; or (iii) the consummation by the Company of (x) a merger, consolidation, reorganization, or business combination, (y) a sale or other disposition of all or substantially all of the Company’s assets in any single transaction or series of related transactions or (z) the acquisition of assets or stock of another entity, in each case other than a transaction (A) which results in the Company’s voting securities outstanding immediately before the transaction continuing to represent (either by remaining outstanding or by being converted into voting securities of the Company or the person that, as a result of the transaction, controls, directly or indirectly, the Company or owns, directly or indirectly, all or substantially all of the Company’s assets or otherwise succeeds to the business of the Company (the Company or such person, the “Successor Entity”)) directly or indirectly, at least a majority of the combined voting power of the Successor Entity’s outstanding voting securities immediately after the transaction, and (B) after which no person or group beneficially owns voting securities representing 50% or more of the combined voting power of the Successor Entity; provided, however, that no person or group shall be treated for purposes of this clause (B) as beneficially owning 50% or more of the combined voting power of the Successor Entity solely as a result of the voting power held in the Company prior to the consummation of the transaction.

For purposes of the change in control agreement, “Cause” means any of the following: (i) executive’s commission of an act of fraud, embezzlement or theft against the Company or its affiliates; (ii) executive’s conviction of, or plea of no contest to, a felony or crime involving moral turpitude; (iii) executive’s refusal to perform material duties as an employee of the Company, which to the extent curable, remains uncured for 30 days following executive’s receipt of written notice thereof; (iv) executive’s material breach of any material policy of the Company or any of its affiliates that is applicable to executive or of any material agreement with the Company or any of its affiliates, including any confidentiality and restrictive covenant agreements, which to the extent curable, remains uncured for 30 days following executive’s receipt of written notice thereof; (v) executive’s gross negligence, willful misconduct or any other act of willful disregard for the Company’s or any of its affiliates’ best interests; or (vi) executive’s refusal to cooperate with a

DIRECTOR COMPENSATION

Overview

Under our non-employee director compensation program, each non-employee director is eligible to receive the following amounts for their services on our Board of Directors:

31

Table of Contents

Options granted to our non-employee directors under the program have an exercise price equal to the fair market value of our ordinary shares on the date of grant and expire not later than ten years after the date of grant. The options granted upon a director’s initial election or appointment vest in thirty-six (36) substantially equal monthly installments following the date of grant. The options and restricted share units granted annually to directors vest in a single installment on the earlier of the day before the next annual general meeting or the first anniversary of the date of grant. In addition, all unvested options and restricted share units vest in full upon the occurrence of a change in control. For restricted share unit grants, the directors may elect whether to defer the settlement of their restricted share unit awards under the Deferred Compensation Plan for Non-Employee Directors. See the section entitled “Deferred Compensation Plan for Non-Employee Directors” below for additional information.

2022 Director Compensation Table

The following table sets forth the total director compensation in 2022.

Table of Contents

The table below shows the aggregate number of option awards (exercisable and unexercisable), restricted share units and deferred share units held as of December 31, 2022 by each non-employee director who was serving as of December 31, 2022.

Deferred Compensation Plan for Non-Employee Directors

In December 2021, we adopted the Deferred Compensation Plan for Non-Employee Directors, or the Deferred Compensation Plan, which permits our non-employee directors to defer payment of all or a portion of the restricted share units granted to them for their service as a director. A participant’s election to defer receipt of these awards must generally be made prior to the year to which the award relates (or, for a newly nominated director, within 30 days following the date of the commencement of the director’s service as a director). Deferred awards are credited to an account in an equal amount of deferred share units with dividend equivalent rights. Dividend equivalent rights entitle a participant, as of a dividend payment date, to have credited to the participant’s deferred compensation account a number of additional deferred share units equal to the amount of any ordinary cash dividend paid by the Company on the number of ordinary shares equivalent to the number of deferred share units in the participant’s deferred compensation account as of the record date for the dividend, divided by the fair market value of one ordinary share on the dividend payment date. Deferred share units (including any additional deferred share units resulting from dividend equivalent rights) are subject to the same vesting or other forfeiture conditions that would have otherwise applied to the deferred awards. With respect to each deferred share unit granted under the Deferred Compensation Plan, we will issue to the participant one ordinary share (or, at the election of the Compensation Committee, an equivalent cash amount based on the fair market value of an ordinary share on the date immediately preceding the payment date) on the first to occur of (i) within 90 days following the participant’s separation from service (within the meaning of Section 409A of the Internal Revenue Code), (ii) immediately prior to, on, or within 30 days following a change in control or (iii) upon the participant’s death. If the participant is a “specified employee” within the meaning of Section 409A of the Internal Revenue Code, the payment will instead be made on the later to occur of the scheduled distribution date and the first day of the seventh month following the date of the participant’s separation from service or, if earlier, the date of the participant’s death.

SHARE OWNERSHIP

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth information relating to the beneficial ownership of our ordinary shares as of March 31, 2023, by:

The number of shares beneficially owned by each shareholder is determined under rules issued by the SEC. Under these rules, a person is deemed to be a “beneficial” owner of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. Except as indicated in the footnotes below, we believe, based on the information furnished to us, that the individuals and entities named in the table below have sole voting and investment power with respect to all of our ordinary shares beneficially owned by them, subject to any applicable community property laws.

The percentage of shares beneficially owned is computed on the basis of 48,686,263 of our ordinary shares outstanding as of March 31, 2023. Ordinary shares that a person has the right to acquire within 60 days of March 31, 2023 are deemed outstanding for purposes of computing the percentage ownership of the person holding such rights, but are not deemed outstanding for purposes of computing the percentage ownership of any other person, except with respect to the percentage ownership of all directors and executive officers as a group. Unless otherwise indicated below, the address for each beneficial owner listed is c/o MeiraGTx Holdings plc, 450 East 29^th Street, 14^th Floor, New York, New York 10016.

CERTAIN TRANSACTIONS WITH RELATED PERSONS

Policies and Procedures on Transactions with Related Persons

Our Board of Directors has adopted a written related person transaction policy setting forth the policies and procedures for the review and approval or ratification of related person transactions. This policy covers, with certain exceptions set forth in Item 404 of Regulation S-K, any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we were or are to be a participant, where the amount involved exceeds $5,000 in any one fiscal year and a “related person” (as defined under Regulation S-K) had, has or will have a direct or indirect material interest.

Our finance team is primarily responsible for developing and implementing processes and procedures to obtain information regarding related persons with respect to potential related person transactions and then determining, based on the facts and circumstances and in consultation with counsel as deemed necessary or advisable, whether such potential related person transactions constitute related person transactions requiring compliance with the policy. In addition, any potential related person transaction that is proposed to be entered into must be reported to our principal financial officer by both the related person and the person at the Company responsible for such potential related person transaction.

Unless exempted from the policy, the principal financial officer shall present to the Audit Committee (or the chairman of the Audit Committee) the related person transaction for review and the Audit Committee (or, where Audit Committee approval is not feasible, the chairman, subject to further ratification by the Audit Committee) shall approve or disapprove the related person transaction. In determining whether to approve the related person transaction, the Audit Committee is to review all relevant facts and circumstances, including whether the related person transaction is entered into on terms comparable to those that could be obtained on an arms-length basis with an unrelated third party, the extent of the related person’s interest in the transaction and taking into account the conflicts of interest and corporate opportunity provisions of the Company’s Code of Business Conduct and Ethics.

The following is a summary of transactions since January 1, 2021 that constitute related person transactions required to be disclosed pursuant to the applicable provisions of Item 404(a) and Item 404(d) of Regulation S-K. Each of the transactions described below entered into following the adoption of our related person transaction policy was approved in accordance with such policy or otherwise by the Board of Directors.

Indemnification Agreements

We entered into indemnification agreements with each of our directors and executive officers. These agreements, among other things, require us to indemnify each director (and in certain cases their related investment funds) and executive officer against all expenses such as attorneys’ fees, judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by the director or executive officer or on his or her behalf, in connection with such proceeding or any claim, issue or matter therein, if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of our Company, and with respect to any criminal proceeding, had no reasonable cause to believe the person’s conduct was unlawful.

ARE Agreement

In May 2019, we entered into a vivarium use agreement with ARE-East River Science Park, LLC (“ARE”) to lease space in a vivarium maintained in our New York office building for research and development purposes. ARE is an entity affiliated with Alexandria Real Estate Equities, Inc., which is a minority shareholder of the Company and whose executive chairman and founder, Joel S. Marcus, served as a director of the Company through June 2022. During 2021, we and ARE amended the vivarium use agreement three times to increase the size of our space in the vivarium, with the most recent amendment in October 2021 resulting in an annual rent of $151,505. During 2021 and 2022, we paid ARE an aggregate amount of $88,761 and $141,737, respectively.

Debt Financing

On August 2, 2022, we, as borrower, and our wholly-owned subsidiaries MeiraGTx UK II Limited and MeiraGTx Ireland DAC, as guarantors (the “Subsidiary Guarantors”), entered into a senior secured financing arrangement (the “Financing Agreement”) by and among us, the Subsidiary Guarantors, the lenders and other parties from time to time party thereto and Perceptive Credit Holdings, as administrative agent and lender. Perceptive Credit Holdings is an affiliate of Perceptive, a beneficial owner of more than 5% of the ordinary shares of the Company. Additionally, Ellen Hukkelhoven, Ph.D., a director of the Company, is the Head of Biotechnology Investments at Perceptive. On December 19, 2022, the Financing Agreement was converted to a note purchase agreement (as converted, the “Note Purchase Agreement”) between the same parties and under substantially the same terms and conditions as the Financing Agreement. The Note Purchase Agreement provides for an initial $75.0 million notes issuance (the “Tranche 1 Notes”), and we may request an additional $25.0 million notes issuance to be made available at Perceptive Credit Holding’s sole discretion before August 2, 2024. Outstanding amounts under the Note Purchase Agreement bear interest at a fluctuating rate per annum equal to 10.00% plus the secured overnight financing rate administered by the Federal Reserve Bank of New York for a one-month tenor, subject to a 1.00% floor. The annual interest rate was 13.02% at December 31, 2022. As of December 31, 2022, the outstanding balance of the Tranche 1 Notes was $75.0 million plus accrued interest of $4.0 million. During the year ended December 31, 2022, we recorded interest expense of $4.0 million. In connection with entering into the Financing Agreement, we granted warrants to Perceptive Credit Holdings to purchase up to (i) 400,000 ordinary shares of the Company at an exercise price of $15.00 per share and (ii) 300,000 ordinary shares of the Company at an exercise price of $20.00 per share. The warrants are exercisable immediately and expire on August 2, 2027.

SHAREHOLDER PROPOSALS AND DIRECTOR NOMINATIONS

Shareholders who intend to have a proposal considered for inclusion in our proxy materials for presentation at our 2024 Annual Meeting pursuant to Rule 14a-8 under the Exchange Act must submit the proposal to our Secretary at our offices at 450 East 29^th Street, 14^th Floor, New York, New York 10016, in writing not later than December 29, 2023.

Under our Articles all business carried out at a general meeting shall be deemed special with the exception of sanctioning a dividend, the consideration of the accounts, balance sheets, any report of the Board or of the Company’s auditors, and the fixing of the remuneration of the Company’s auditors. No special business shall be transacted at any general meeting without the consent of all shareholders entitled to receive notice of that meeting unless notice of such special business has been given in the notice convening that meeting. In addition, no business may be transacted at any general meeting other than business that is either specified in the notice of the meeting given by or at the direction of the Board (including on the requisition of shareholders in accordance with the Articles) or otherwise properly brought before an annual general meeting by or at the direction of the Board. A general meeting may be called by the Board of Directors or any other person authorized to do so in our Articles. Under our Articles, general meetings shall also be convened on the requisition in writing of any shareholder or shareholders entitled to attend and vote at general meetings of the Company and to exercise at least a majority of the voting power permitted to be exercised at any such meeting, deposited at the registered office of the Company specifying the objects of the meeting for a date no later than 21 days from the date of deposit of the requisition signed by such shareholders and, if the Board does not convene such meeting for a date not later than 45 days after the date of such deposit, such shareholders themselves may convene the general meeting in the same manner, as nearly as possible, as that in which general meetings may be convened by the Board.

We reserve the right to reject, rule out of order or take other appropriate action with respect to any proposal that does not comply with these or other applicable requirements.

HOUSEHOLDING

SEC rules permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements and notices with respect to two or more shareholders sharing the same address by delivering a single proxy statement or a single notice addressed to those shareholders. This process, which is commonly referred to as “householding,” provides cost savings for companies and helps the environment by conserving natural resources. Some brokers household proxy materials, delivering a single proxy statement or notice to multiple shareholders sharing an address unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker that they will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement or notice, or if your household is receiving multiple copies of these documents and you wish to request that future deliveries be limited to a single copy, please notify your broker. You can also request prompt delivery of a copy of this Proxy Statement and the Annual Report by contacting Broadridge Financial Solutions, Inc. at (866) 540-7095 or in writing at Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717.
