NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

To Be Held on June 6, 2024

Dear Stockholder:

You are cordially invited to attend the Annual Meeting of Stockholders of Aclaris Therapeutics, Inc., a Delaware corporation (the “Company”). The Annual Meeting will be held on Thursday, June 6, 2024 at 9:00 a.m. Eastern Time. The Annual Meeting will be a virtual stockholder meeting through which you can listen to the meeting, submit questions and vote online. The Annual Meeting can be accessed by visiting www.virtualshareholdermeeting.com/ACRS2024 and entering your 16-digit control number (included in the Notice of Internet Availability of Proxy Materials that will be mailed to you). You will not be able to attend the Annual Meeting in person. The purpose of the Annual Meeting will be the following:

These items of business are more fully described in the proxy statement accompanying this Notice.

The record date for the Annual Meeting is April 16, 2024. Only stockholders of record at the close of business on that date may vote at the meeting or any postponement or adjournment thereof.

We have elected to provide access to our proxy materials over the internet under the Securities and Exchange Commission’s “notice and access” rules. As a result, we are mailing to our stockholders a Notice of Internet Availability of Proxy Materials instead of paper copies of the proxy statement and our 2023 Annual Report. The notice contains instructions on how to access those documents over the internet. The notice also contains instructions on how stockholders can receive a paper copy of our proxy materials, including the proxy statement, our 2023 Annual Report and a form of proxy card or voting instruction form. We believe that providing our proxy materials over the internet increases the ability of our stockholders to connect with the information they need, while reducing the environmental impact and cost of our Annual Meeting.

By Order of the Board of Directors

PROXY STATEMENT

FOR THE 2024 ANNUAL MEETING OF STOCKHOLDERS

To be held on June 6, 2024

QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING

Why did I receive a Notice of Internet Availability of Proxy Materials on the internet instead of a full set of Proxy Materials?

Pursuant to rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to provide access to our Proxy Materials (defined below) over the internet. Accordingly, on or about April 25, 2024, we are sending you a Notice of Internet Availability of Proxy Materials (the “Notice of Internet Availability”) because the Board of Directors (the “Board”) of Aclaris Therapeutics, Inc. (sometimes referred to as the “Company” or “Aclaris”) is soliciting your proxy to vote at the 2024 Annual Meeting of Stockholders, including at any adjournments or postponements thereof (the “Annual Meeting”). The Notice of 2024 Annual Meeting of Stockholders (“Notice of Annual Meeting”), this proxy statement and proxy card or, for shares held in street name (held for your account by a broker or other nominee), voting instruction form, and our 2023 Annual Report (collectively the “Proxy Materials”) are available to stockholders on the internet.

The Notice of Internet Availability will provide instructions as to how stockholders may access and review the Proxy Materials on the website referred to in the Notice of Internet Availability or, alternatively, how to request that a copy of the Proxy Materials, including a proxy card, be sent to them by mail. The Notice of Internet Availability will also provide voting instructions. Please note that, while our Proxy Materials are available at the website referenced in the Notice of Internet Availability, and our Notice of Annual Meeting, proxy statement and Annual Report on Form 10-K for the year ended December 31, 2023 are available on our website, no other information contained on either website is incorporated by reference in or considered to be a part of this document.

We intend to mail the Notice of Internet Availability on or about April 25, 2024 to all stockholders of record entitled to vote at the Annual Meeting. The Proxy Materials will be made available to stockholders on the internet on the same date.

Will I receive any Proxy Materials by mail?

Other than the Notice of Internet Availability, you will not receive any Proxy Materials via mail unless (1) you request a printed copy of the Proxy Materials in accordance with the instructions set forth in the Notice of Internet Availability or (2) we elect, in our discretion, to send you a proxy card and a second Notice of Internet Availability.

How do I attend the Annual Meeting?

The meeting will be held on Thursday, June 6, 2024 at 9:00 a.m. Eastern Time. The Annual Meeting will be a virtual stockholder meeting through which you can listen to the meeting, submit questions and vote online. The Annual Meeting can be accessed by visiting www.virtualshareholdermeeting.com/ACRS2024 and entering your 16-digit control number which is included in the Notice of Internet Availability that will be mailed to you. The virtual meeting platform is fully supported across browsers and devices running the most updated version of applicable software and plugins. Participants should ensure that they have a strong internet connection wherever they intend to participate in the meeting. You will not be able to attend the Annual Meeting in person.

Whether or not you participate in the Annual Meeting, it is important that you vote your shares.

​

Why is the Annual Meeting a virtual, online meeting?

We have decided to hold a virtual meeting to facilitate stockholder participation in the Annual Meeting. Stockholders attending the virtual meeting will be afforded the same rights and opportunities to participate as they would at an in-person meeting.

Information on how to vote online during the Annual Meeting is discussed below.

Can I ask questions at the Annual Meeting?

Only stockholders of record as of the record date for the Annual Meeting and their proxy holders may submit questions or comments.

If you would like to submit a question, you may do so by joining the virtual Annual Meeting at www.virtualshareholdermeeting.com/ACRS2024 and typing your question in the box in the Annual Meeting portal.

To help ensure that we have a productive and efficient meeting, and in fairness to all stockholders in attendance, you will also find posted our rules of conduct for the Annual Meeting when you log in prior to its start. In accordance with the rules of conduct, we ask that you limit your remarks to one brief question or comment that is relevant to the Annual Meeting or our business and that remarks are respectful of your fellow stockholders and meeting participants. Questions may be grouped by topic by our management with a representative question read aloud and answered. In addition, questions may be ruled as out of order if they are, among other things, irrelevant to our business, related to pending or threatened litigation, disorderly, repetitious of statements already made, or in furtherance of the speaker’s own personal, political or business interests. Questions will be addressed in the Q&A portion of the Annual Meeting, as time permits.

What if I need technical assistance accessing or participating in the virtual Annual Meeting?

If you encounter any difficulties accessing the virtual Annual Meeting during the check-in or meeting time, please call the technical support number that will be posted on the Virtual Stockholder Meeting login page. Technical support will be available starting at 8:55 a.m. Eastern Time on June 6, 2024.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on April 16, 2024 will be entitled to vote at the Annual Meeting. On this record date, there were 71,264,786 shares of common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If at the close of business on April 16, 2024 your shares were registered directly in your name with Aclaris Therapeutics, Inc.’s transfer agent, Broadridge Corporate Issuer Solutions, Inc., then you are a stockholder of record. As a stockholder of record, you may vote at the meeting or vote by proxy. Whether or not you plan to attend the meeting, we urge you to fill out and return a proxy card that you may request or that we may elect to deliver at a later time, or vote by proxy over the telephone or on the internet as instructed below to ensure your vote is counted.

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

If at the close of business on April 16, 2024 your shares were held, not in your name, but rather in an account at a brokerage firm, bank or other similar organization, then you are the beneficial owner of shares held in “street name” and the Notice of Internet Availability is being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker, bank or other agent regarding how to vote the shares in your account. You are also invited to attend the Annual Meeting via the internet. Whether or not you plan to attend the Annual Meeting via the internet, we urge you to fill out and return a proxy card or vote by proxy over the telephone or on the internet as instructed below to ensure your vote is counted.

​

Will a list of stockholders entitled to vote at the Annual Meeting be available?

​

Our list of stockholders as of April 16, 2024 will be available for inspection at our corporate office for the 10 days prior to the Annual Meeting. If you want to inspect the stockholder list, call our office at 484-324-7933 to speak with our Investor Relations department to schedule an appointment.

What am I voting on?

There are three matters scheduled for a vote:

What if another matter is properly brought before the meeting?

The Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment.

How do I vote?

For Proposal 1, you may either vote “For” all the nominees to the Board or you may “Withhold” your vote for any nominee you specify. For Proposals 2 and 3, you may vote “For” or “Against” or abstain from voting.

The procedures for voting are fairly simple:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote at the Annual Meeting or vote by proxy in one of three ways: online, by telephone or using a proxy card that you may request or that we may elect to deliver at a later time. Whether or not you plan to attend the meeting via the internet, we urge you to vote by proxy to ensure your vote is counted. You may still attend the meeting via the internet and vote during the meeting even if you have already voted by proxy.

​

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a notice containing voting instructions from that organization rather than from us. Simply follow the instructions in the notice to ensure that your vote is counted. Alternatively, you may vote by telephone or on the internet as instructed by your broker or bank. To vote online at the Annual Meeting, please follow the instructions at www.virtualshareholdermeeting.com/ACRS2024. You will need the 16-digit control number, which is included in the Notice of Internet Availability that will be mailed to you. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the Annual Meeting and vote online even if you have already voted by proxy.

​

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you own at the close of business on April 16, 2024.

If I am a stockholder of record and I do not vote, or if I return a proxy card or otherwise vote without giving specific voting instructions, what happens?

If you are a stockholder of record and do not vote by completing a proxy card, by telephone, or through the internet either before or during the Annual Meeting, your shares will not be voted.

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, “For” the election of the nominees for director, “For” the advisory approval of the compensation of our named executive officers, and “For” the ratification of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

If I am a beneficial owner of shares held in street name and I do not provide my broker or bank with voting instructions, what happens?

If you are a beneficial owner of shares held in street name and you do not instruct your broker, bank or other agent how to vote your shares, your broker, bank or other agent may still be able to vote your shares in its discretion. In this regard, under the rules of the New York Stock Exchange (NYSE), brokers, banks and other securities intermediaries that are subject to NYSE rules may use their discretion to vote your “uninstructed” shares with respect to matters considered to be “routine” under NYSE rules, but not with respect to “non-routine” matters. In this regard, Proposals 1 and 2 are considered to be “non-routine” under NYSE rules, meaning that your broker may not vote your shares on those proposals in the absence of your voting instructions. However, Proposal 3 is considered to be a “routine” matter under NYSE rules, meaning that if you do not return voting instructions to your broker by its deadline, your shares may be voted by your broker in its discretion on Proposal 3.

​

If you a beneficial owner of shares held in street name, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent or vote online at the Annual Meeting.

​

Who is paying for this proxy solicitation?

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

What does it mean if I receive more than one Notice of Internet Availability?

If you receive more than one Notice of Internet Availability, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the notices to ensure that all of your shares are voted.

Can I change my vote after submitting my proxy?

Stockholder of Record: Shares Registered in Your Name

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

Your most current proxy card or telephone or internet proxy is the one that is counted.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If your shares are held by your broker, bank or other agent, you should follow the instructions provided by that organization or vote online at the Annual Meeting.

When are stockholder proposals due for next year’s Annual Meeting?

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by December 26, 2024, to our Corporate Secretary at 701 Lee Road, Suite 103, Wayne, Pennsylvania 19087. If you wish to nominate an individual for election at, or bring business other than through a stockholder proposal before, the 2025 Annual Meeting of Stockholders, you must deliver your notice to our Corporate Secretary at the address above between February 6, 2025 and March 8, 2025; provided, however that if next year’s annual meeting is advanced more than 30 days prior to or delayed by more than 30 days after June 6, 2025, your proposal must be submitted not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the tenth day following the day on which public announcement of the date of such meeting is first made. Your notice to the Corporate Secretary must set forth information specified in our amended and restated bylaws, including your name and address and the class and number of shares of our stock that you beneficially own. In addition, stockholders who intend to solicit proxies in support of director nominees other than the Board’s nominees must also comply with the additional requirements of Rule 14a-19(b).

If you propose to bring business before an annual meeting other than a director nomination, your notice must also include, as to each matter proposed, the following: (1) a brief description of the business desired to be brought before the annual

5

​

meeting and the reasons for conducting that business at the annual meeting and (2) any material interest you have in that business. If you propose to nominate an individual for election as a director, your notice must also include, as to each person you propose to nominate for election as a director, the following: (1) the name, age, business address and residence address of the person, (2) the principal occupation or employment of the person, (3) the class and number of shares of our stock that are owned of record and beneficially owned by the person, (4) the date or dates on which the shares were acquired and the investment intent of the acquisition and (5) any other information concerning the person as would be required to be disclosed in a proxy statement soliciting proxies for the election of that person as a director in an election contest (even if an election contest is not involved), or that is otherwise required to be disclosed pursuant to Section 14 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations promulgated under the Exchange Act, including the person’s written consent to being named as a nominee and to serving as a director if elected. We may require any proposed nominee to furnish other information as we may reasonably require to determine the eligibility of the proposed nominee to serve as an independent director or that could be material to a reasonable stockholder’s understanding of the independence, or lack of independence, of the proposed nominee.

For more information, and for more detailed requirements, please refer to our amended and restated bylaws, filed as an exhibit to our most recent Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on February 27, 2024.

How are votes counted?

Votes will be counted by the inspector of election appointed for the meeting.

What are “broker non-votes”?

A “broker non-vote” occurs when your broker submits a proxy for the meeting with respect to “routine” matters but does not vote on “non-routine” matters because you did not provide voting instructions on these matters. These unvoted shares with respect to the “non-routine” matters are counted as “broker non-votes.” Proposals 1 and 2 are considered to be “non-routine” under NYSE rules, and we therefore expect broker non-votes to exist in connection with these proposals.

​

As a reminder, if you a beneficial owner of shares held in street name, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent or vote online at the Annual Meeting.

6

​

How many votes are needed to approve each proposal?

The following table summarizes the minimum vote needed to approve each proposal and the effect of abstentions and broker non-votes.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote are present at the Annual Meeting or represented by proxy. At the close of business on the record date, there were 71,264,786 shares outstanding and entitled to vote. Thus, the holders of 35,632,394 shares must be present or represented by proxy at the Annual Meeting to have a quorum.

Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, either the chair of the Annual Meeting or the holders of a majority of shares present at the meeting or represented by proxy may adjourn the Annual Meeting to another date.

How can I find out the results of the voting at the Annual Meeting?

Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the meeting, we intend to file a Form 8‑K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

PROPOSAL 1

ELECTION OF DIRECTORS

Our Board is divided into three classes. Each class consists, as nearly as possible, of one-third of the total number of directors, and each class has a three-year term. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy in a class, including vacancies created by an increase in the number of directors, shall serve for the remainder of the full term of that class and until the director’s successor is duly elected and qualified.

The Board presently has nine members. There are three directors in the class whose term of office expires in 2024: Christopher Molineaux, Bryan Reasons and Vincent Milano. One of these directors, Bryan Reasons, notified us that he decided to not stand for re-election at the Annual Meeting and his term will expire at the Annual Meeting. In addition, Andrew Powell notified us that he was resigning effective as of the Annual Meeting. The Board has approved a decrease in the authorized size of the Board to seven members effective immediately following the Annual Meeting. Each of the nominees listed below is currently a director of the Company who was previously elected by the stockholders. If elected at the Annual Meeting, each of these nominees would serve until the 2027 Annual Meeting of Stockholders and until his successor has been duly elected and qualified, or, if sooner, until the director’s death, resignation or removal. It is our policy to invite and encourage directors and nominees for director to attend the Annual Meeting. Six of the ten then serving directors attended the 2023 Annual Meeting of Stockholders.

Directors are elected by a plurality of the votes of the holders of shares present or represented by proxy and entitled to vote on the election of directors at the Annual Meeting. Accordingly, the two nominees receiving the highest number of affirmative votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the nominees named below. If any nominee becomes unavailable for election as a result of an unexpected occurrence, shares that would have been voted for that nominee may instead be voted for the election of a substitute nominee proposed by our Board. 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.

The Nominating and Corporate Governance Committee of our Board seeks to assemble a board that, as a whole, possesses the appropriate balance of professional and industry knowledge, financial expertise and high-level management experience necessary to oversee and direct our business. To that end, the Nominating and Corporate Governance Committee has identified and evaluated the nominees in the broader context of the Board’s overall composition, with the goal of recruiting members who complement and strengthen the skills of other members and who also exhibit integrity, collegiality, sound business judgment and other qualities that the Nominating and Corporate Governance Committee views as critical to effective functioning of the Board.

The biographies below include information, as of the date of this proxy statement, regarding the specific and particular experience, qualifications, attributes or skills of each nominee that led the Nominating and Corporate Governance Committee to recommend that person as a nominee for director. However, each member of the committee may have a variety of reasons why he or she believes a particular person would be an appropriate nominee for the Board, and these views may differ from the views of other members.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

INDEPENDENCE OF THE BOARD OF DIRECTORS

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

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and our company, senior management and independent auditors, the Board has affirmatively determined that eight of our nine current directors are independent directors within the meaning of the applicable Nasdaq listing standards: Mr. Humphries, Dr. Mehra, Mr. Molineaux, Mr. Powell, Mr. Reasons, Dr. Schiff, Dr. Gowen and Mr. Milano. In making these determinations, the Board found that none of these directors had a material or other disqualifying relationship with our company. Dr. Walker, as our Interim President and Chief Executive Officer, is not independent as a result of his employment by our company.

BOARD LEADERSHIP STRUCTURE

Dr. Walker was appointed as the chair of our Board effective January 2023. The Chair has authority, among other things, to call and preside over Board meetings, to set meeting agendas and to determine materials to be distributed to the Board and, as a result, has substantial ability to shape the work of the Board. However, following the departure of Douglas Manion, our former Chief Executive Officer, Dr. Walker was appointed as our Interim President and Chief Executive Officer in January 2024.

Our Board maintains the flexibility to determine whether the roles of Chair and Chief Executive Officer should be combined or separated, based on what it believes is in the best interests of the Company at a given point in time. The Board

11

​

believes that this flexibility is in the best interest of the Company and that a one-size-fits-all approach to corporate governance, with a mandated independent Chair, would not result in better governance or oversight.

At this time, the Board believes that our current Chief Executive Officer is best situated to serve as Chair of the Board. Dr. Walker co-founded our company and is highly knowledgeable and has longstanding experience with respect to our business, operations and industry and ongoing executive responsibility for the Company. Dr. Walker is well positioned to identify strategic priorities and lead the Board’s consideration and analysis of such priorities. In addition, Dr. Walker offers a robust understanding of risks facing the Company. In the Board’s view, this enables the Board to better understand the Company and work with management to enhance stockholder value. Further, the Board believes that this structure enables it to better fulfill its risk oversight responsibilities and enhances the ability of the Chief Executive Officer to effectively communicate the Board’s view to management.

Because the Company does not have an independent chair, the Company has designated a lead independent director, Mr. Molineaux, who is responsible for coordinating the activities of the independent directors. The Board believes that the position of lead independent director helps to reinforce the independence of the Board as a whole. The lead independent director is empowered to, among other duties and responsibilities, preside over Board meetings in the absence of the Chair, preside over and establish the agendas for meetings of the independent directors, act as liaison between the Chair and the independent directors, provide feedback on the information sent to the Board, preside over any portions of Board meetings at which the evaluation or compensation of the Chief Executive Officer is presented or discussed and, as appropriate upon request, act as a liaison to stockholders. In addition, it is the responsibility of the lead independent director to coordinate between the Board and management with regard to the determination and implementation of responses to any problematic risk management issues. As a result, the Company believes that the lead independent director can help ensure the effective independent functioning of the Board in its oversight responsibilities. In addition, the Company believes that the lead independent director is better positioned to build a consensus among directors and to serve as a conduit between the other independent directors and the Chair, for example, by facilitating the inclusion on meeting agendas of matters of concern to the independent directors.

​

ROLE OF THE BOARD IN RISK OVERSIGHT

One of the Board’s key functions is informed oversight of the Company’s risk management process. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through various Board standing committees that address risks inherent in their respective areas of oversight, including operational, financial, legal and regulatory, cybersecurity, strategic and reputational risks. In particular, our Board is responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for the Company. Our Audit Committee has the responsibility to consider and discuss our major financial and cybersecurity risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The Audit Committee also monitors compliance with legal and regulatory requirements, in addition to oversight of the performance of our internal audit function, if and to the extent that we establish such a function. Our Nominating and Corporate Governance Committee monitors the effectiveness of our corporate governance principles, including whether they are successful in preventing illegal or improper liability-creating conduct. Our Nominating and Corporate Governance Committee also periodically reviews and assesses the adequacy of our Corporate Governance Guidelines. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. It is the responsibility of the committee chairs to report findings regarding material risk exposures to the Board as quickly as possible. The Lead Independent Director coordinates between the Board and management with regard to the determination and implementation of responses to any problematic risk management issues.

MEETINGS OF THE BOARD OF DIRECTORS

The Board met seven times during 2023. Each Board member attended 75% or more of the aggregate number of meetings of the Board and of the committees on which he or she served, held during the portion of 2023 for which he or she was a director or committee member.

12

​

As required under applicable Nasdaq listing standards, during 2023 our independent directors met in regularly scheduled executive sessions at which only independent directors were present.

INFORMATION REGARDING COMMITTEES OF THE BOARD OF DIRECTORS

The Board has an Audit Committee, a Compensation Committee, a Nominating and Corporate Governance Committee, and a Research and Development Committee. The following table provides membership and meeting information for 2023 for the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee. The Board has determined that each member of the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee meets the applicable Nasdaq rules and regulations regarding “independence” and that each member is free of any relationship that would impair his or her individual exercise of independent judgment with regard to the Company.

*Committee Chair

Below is a description of each of the committees of the Board. Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities.

Audit Committee

The Audit Committee is currently composed of three directors: Mr. Milano, Dr. Gowen and Mr. Molineaux. Mr. Milano succeeded Mr. Reasons as chair of the Audit Committee, effective as of April 1, 2024, and currently serves as the chair of the Audit Committee. Mr. Molineaux succeeded Mr. Powell as a member of the Audit Committee, effective as of April 1, 2024. The Audit Committee met six times during 2023. The Board has adopted a written Audit Committee charter that is available to stockholders on the Company’s website at www.aclaristx.com.

The Board reviews the Nasdaq listing standards definition of independence for Audit Committee members on an annual basis and has determined that all members of the Company’s Audit Committee are independent (as independence is currently defined in Rule 5605(c)(2)(A)(i) and (ii) of the Nasdaq listing standards and under Rule 10A-3 under the Exchange Act).

The Board has also determined that Mr. Milano qualifies as an “audit committee financial expert,” as defined in applicable SEC rules. The Board made a qualitative assessment of Mr. Milano’s level of knowledge and experience based on a number of factors, including his formal education and experience as both a chief executive officer and chief financial officer for public reporting companies.

The Audit Committee of the Board was established by the Board in accordance with Section 3(a)(58)(A) of the Exchange Act to oversee the Company’s corporate accounting and financial reporting processes and audits of its financial statements. For this purpose, the Audit Committee performs several functions. The Audit Committee evaluates the performance of and assesses the qualifications of the independent auditors; determines and approves the engagement of the independent auditors; determines whether to retain or terminate the existing independent auditors or to appoint and engage new

13

​

independent auditors; reviews and approves the retention of the independent auditors to perform any proposed permissible non-audit services; monitors the rotation of partners of the independent auditors on the Company’s audit engagement team as required by law; reviews and approves or rejects transactions between the Company and any related persons; confers with management and the independent auditors regarding the effectiveness of internal control over financial reporting; establishes procedures, as required under applicable law, for the receipt, retention and treatment of complaints received by the Company regarding accounting, internal accounting controls or auditing matters and the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters; oversees the Company’s information technology risk exposures, including cybersecurity, data privacy and data security; and meets to review the Company’s annual audited financial statements and quarterly financial statements with management and the independent auditor, including a review of the Company’s disclosures under “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Report of the Audit Committee of the Board of Directors (1)

The Audit Committee has reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2023 with management of the Company. The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The Audit Committee has also received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent accountants’ communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm the accounting firm’s independence. Based on the foregoing, the Audit Committee has 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.

Compensation Committee

The Compensation Committee is currently composed of two directors: Dr. Mehra and Mr. Humphries. Dr. Mehra succeeded Dr. Gowen as the chair of the Compensation Committee, effective April 1, 2024, and currently serves as chair of the Compensation Committee. In addition, Mr. Humphries was appointed to the Compensation Committee, and Dr. Schiff and Mr. Milano came off of the Compensation Committee, effective April 1, 2024. All members of the Company’s Compensation Committee are independent (as independence is currently defined in Rule 5605(d)(2) of the Nasdaq listing standards). The Compensation Committee met five times during 2023. The Board has adopted a written Compensation Committee charter that is available to stockholders on the Company’s website at www.aclaristx.com.

The Compensation Committee of the Board acts on behalf of the Board to review, adopt and oversee the Company’s compensation strategy, policies, plans and programs, including:

14

​

Compensation Committee Processes and Procedures

Typically, the Compensation Committee meets four to five times per year and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with management. The Compensation Committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisers or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of the Company. In addition, under the charter, the Compensation Committee has the authority to obtain, at the expense of the Company, advice and assistance from compensation consultants and internal and external legal, accounting or other advisers and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the Compensation Committee. In particular, the Compensation Committee has the sole authority to retain, in its sole discretion, compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under the charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the Compensation Committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and Nasdaq, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.

After taking into consideration the six factors prescribed by the SEC and Nasdaq, the Compensation Committee engaged Pearl Meyer & Partners, LLC (“Pearl Meyer”), a compensation consulting firm, as a compensation consultant in 2022 and 2023. The Compensation Committee assessed Pearl Meyer’s independence and determined that Pearl Meyer had no conflicts of interest in connection with its provision of services to the Compensation Committee. Specifically, the Compensation Committee engaged Pearl Meyer to serve as its independent compensation adviser. Pearl Meyer’s engagement in 2023 included, but was not limited to, recommending our peer company group for executive and outside director compensation benchmarking, conducting a compensation assessment analyzing the current cash and equity compensation of our executive officers, directors and other senior management against compensation for similarly situated executives and directors at our peer group companies, and assisting with the structuring of incentive compensation arrangements. Our management did not have the ability to direct Pearl Meyer’s work.

In accordance with the Company’s 2015 Equity Incentive Plan (the “2015 Plan”) and the authority delegated to the Compensation Committee by the Board, the Compensation Committee has delegated to the Company’s Chief Executive Officer its authority to grant, without any further action required by the Board or the Compensation Committee, stock options and restricted stock units to employees who are not officers of the Company within specified equity award guidelines established by the Compensation Committee. The purpose of this delegation of authority is to enhance the flexibility of equity award administration and to facilitate the timely grant of equity awards to non-management employees. Such delegation is reviewed and renewed on an annual basis.

The Compensation Committee makes most of the significant adjustments to annual compensation, determined bonus and equity awards and established new performance objectives at one or more meetings typically held during the first quarter of the year. The Compensation Committee also considers matters related to individual compensation, such as compensation for new executive hires, as well as high-level strategic issues, such as the efficacy of our compensation strategy, potential modifications to that strategy and new trends, plans or approaches to compensation, at various meetings throughout the year. Generally, the Compensation Committee’s process comprises two related elements: the determination

15

​

of compensation levels and the establishment of performance objectives for the current year. For executives other than the Chief Executive Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to the Compensation Committee by the Chief Executive Officer. In the case of the Chief Executive Officer, the evaluation of his performance is conducted by the Compensation Committee, which determines any adjustments to his compensation as well as awards to be granted. For all executives and directors as part of its deliberations, the Compensation Committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, tax and accounting information, tally sheets that set forth the total compensation that may become payable to executives in various hypothetical scenarios, executive and director stock ownership information, stock performance data, analyses of historical executive compensation levels and current Company-wide compensation levels and recommendations of the Compensation Committee’s compensation consultant, including analyses of executive and director compensation paid at other companies suggested by the consultant to be comparable to us.

Compensation Committee Interlocks and Insider Participation

Drs. Gowen, Mehra and Schiff and Mr. Milano served as members of our Compensation Committee during 2023. None of our executive officers served during 2023 as a member of the compensation committee (or other committee serving an equivalent function) or of the board of directors of any entity that had one or more of its executive officers serving as a member of our Board or our Compensation Committee. None of the members of our Compensation Committee has ever been an officer or employee of our company.

Compensation Committee Report (1)

The Compensation Committee has reviewed and discussed with management the Compensation Discussion and Analysis contained in this proxy statement. Based on its review and discussion with management, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this proxy statement and incorporated by reference in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee is currently composed of two directors: Mr. Molineaux and Mr. Humphries. Mr. Molineaux currently serves as the chair of the Nominating and Corporate Governance Committee. Mr. Powell came off of the Nominating and Corporate Governance Committee, effective April 1, 2024. All members of the Nominating and Corporate Governance Committee are independent (as independence is currently defined in Rule 5605(a)(2) of the Nasdaq listing standards). The Nominating and Corporate Governance Committee met four times during 2023. The Board has adopted a written Nominating and Corporate Governance Committee charter that is available to stockholders on the Company’s website and www.aclaristx.com.

The Nominating and Corporate Governance Committee of the Board is responsible for identifying, reviewing and evaluating candidates to serve as directors of the Company (consistent with criteria approved by the Board), reviewing and evaluating incumbent directors, recommending to the Board for selection candidates for election to the Board, making recommendations to the Board regarding the membership of the committees of the Board, assessing the performance of management and the Board, and developing a set of corporate governance principles for the Company.

The Nominating and Corporate Governance Committee believes that candidates for director should have certain minimum qualifications, including the ability to read and understand basic financial statements, being over 21 years of age, being able to serve for three years before reaching the retirement age of 79 and having the highest personal integrity and ethics. The Nominating and Corporate Governance Committee also intends to consider such factors as possessing relevant

16

​

expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of the Company, demonstrated excellence in his or her field, having the ability to exercise sound business judgment, diversity and having the commitment to rigorously represent the long-term interests of the Company’s stockholders. However, the Nominating and Corporate Governance Committee retains the right to modify these qualifications from time to time. Candidates for director nominees are reviewed in the context of the current composition of the Board, the operating requirements of the Company and the long-term interests of stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee typically considers diversity, age, skills and such other factors as it deems appropriate, given the current needs of the Board and the Company, to maintain a balance of knowledge, experience and capability. Although the Company does not have a formal policy governing diversity among directors, the Board strives to identify candidates with diverse backgrounds. The Board recognizes the value of overall diversity and considers members’ and candidates’ opinions, perspectives, personal and professional experiences, and backgrounds, including age, gender, race, ethnicity, and country of origin. We believe that the judgment and perspectives offered by a diverse board of directors improves the quality of decision making and enhances our business performance. For additional information regarding the current composition of our Board, see “Election of Directors—Board Diversity Matrix.”

In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance Committee reviews these directors’ overall service to the Company during their terms, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair the directors’ independence. The Nominating and Corporate Governance Committee also takes into account the results of the Board’s self-evaluation, conducted annually on a group and individual basis. The Nominating and Corporate Governance Committee considers suggestions of potential candidates for Board membership made by current Board members and may also engage, if it deems appropriate, a professional search firm. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board and evaluates whether the nominee is independent for Nasdaq purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Nominating and Corporate Governance Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the Board by majority vote.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a stockholder. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee in care of our Corporate Secretary at 701 Lee Road, Suite 103, Wayne, Pennsylvania 19087. Any such recommendation should be delivered at least 90 days, but not more than 120 days, prior to the anniversary date of the mailing of the Company’s proxy statement for the last Annual Meeting of Stockholders. Submissions must include the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information, a description of the proposed nominee’s qualifications as a director and a representation that the nominating stockholder is a beneficial or record holder of the Company’s stock and has been a holder for at least one year. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.

Research and Development Committee

The Research and Development Committee is currently composed of two directors: Dr. Mehra and Dr. Schiff. Dr. Mehra currently serves as the chair of the Research and Development Committee. Dr. Gowen and Dr. Walker came off of the Research and Development Committee, effective April 1, 2024. The Board has adopted a written Research and Development Committee charter that is available to stockholders on the Company’s website at www.aclaristx.com.

The Research and Development Committee is responsible for reviewing the Company’s research and development strategy, reviewing and discussing the quality, direction, effectiveness, and competitiveness of the Company’s research and development programs, providing counsel to management regarding new and emerging research and development trends, advising the Board regarding scientific and research and development matters and reviewing the Company’s pipeline of drug candidates and clinical development performance. In addition, the Research and Development Committee,

17

​

in conjunction with the Board and the Audit Committee, assists with the oversight of the proper and timely disclosure regarding significant issues or problems with ongoing clinical trials, tests or other studies or analyses.

STOCKHOLDER COMMUNICATIONS WITH THE BOARD OF DIRECTORS

The Company considers its relationships with its stockholders to be a high priority. The Company recognizes that stockholders can have divergent interests and different views on the Company’s practices, objectives and time horizons. To ensure that the Board and management have an opportunity to listen to and understand the varying perspectives of the Company’s stockholders, members of the management team and the Board from time to time engage in dialogues with stockholders. As a result of these discussions, management and the Board have gained useful understanding and insight into the views of the Company’s stockholders and will continue to solicit and engage the Company’s stockholders in the future.

The Board has adopted a formal process by which stockholders may communicate with the Board or any of its directors. Stockholders who wish to communicate with the Board may do so by sending written communications addressed to our Corporate Secretary at 701 Lee Road, Suite 103, Wayne, Pennsylvania 19087. Each communication must set forth:

The Secretary will review each communication. The Secretary will forward such communication to the Board or to any individual director to whom the communication is addressed unless the communication contains advertisements or solicitations or is unduly hostile, threatening or similarly inappropriate, in which case the Secretary shall discard the communication.

CODE OF ETHICS

We have adopted the Aclaris Therapeutics, Inc. Code of Business Conduct and Ethics that applies to all officers, directors and employees. The Code of Business Conduct and Ethics is available on our website at www.aclaristx.com. If we make any substantive amendments to the Code of Business Conduct and Ethics or grant any waiver from a provision of the Code of Business Conduct and Ethics to any executive officer or director, we will promptly disclose the nature of the amendment or waiver on our website.

CORPORATE GOVERNANCE GUIDELINES

We have adopted the Aclaris Therapeutics, Inc. Corporate Governance Guidelines to assure that the Board will have the necessary authority and practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The guidelines are also intended to align the interests of directors and management with those of our stockholders. The Corporate Governance Guidelines set forth the practices the Board intends to follow with respect to board composition and selection, board meetings and involvement of senior management, Chief Executive Officer performance evaluation and succession planning and board committees and compensation. The Corporate Governance Guidelines are available on our website at www.aclaristx.com.

Proposal 2

ADVISORY VOTE ON EXECUTIVE COMPENSATION

At the 2021 Annual Meeting of Stockholders, our stockholders indicated their preference that we solicit a non-binding advisory vote on the compensation of our named executive officers, commonly referred to as a “say-on-pay vote,” every year. We are following that preference and are again asking the stockholders this year to approve, on an advisory basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with SEC rules.

This vote is not intended to address any specific item of compensation, but rather the overall compensation of the Company’s named executive officers and the philosophy, policies and practices described in this proxy statement. The compensation of the Company’s named executive officers subject to the vote is disclosed in the Compensation Discussion and Analysis, the compensation tables and the related narrative disclosures that accompany the compensation tables contained in the “Executive Compensation” section in this proxy statement. As discussed in those disclosures, the Company believes that its compensation policies and decisions are strongly aligned with our stockholders’ interests and consistent with current market practices. Compensation of the Company’s named executive officers is designed to enable the Company to attract and retain talented and experienced executives to lead the Company successfully in a competitive environment.

Accordingly, the Board is asking the stockholders to indicate their support for the compensation of the Company’s named executive officers as described in this proxy statement by casting a non-binding advisory vote “FOR” the following resolution:

“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, the compensation tables and narrative discussion, is hereby APPROVED.”

Because the vote is advisory, it is not binding on the Board or the Company. Nevertheless, the views expressed by the stockholders, whether through this vote or otherwise, are important to management and the Board and, accordingly, the Board and the Compensation Committee intend to consider the results of this vote in making determinations in the future regarding executive compensation arrangements.

Advisory approval of this proposal requires the vote of the holders of a majority of the shares present or represented by proxy and entitled to vote on the matter at the Annual Meeting. Unless the Board decides to modify the frequency of soliciting say-on-pay votes, the next scheduled say-on-pay vote will be at the 2025 Annual Meeting of Stockholders.

The Board Of Directors Recommends

A Vote In Favor Of Proposal 2.

PROPOSAL 3

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board has selected PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024 and has further directed that management submit the selection of its independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. PricewaterhouseCoopers LLP has audited the Company’s financial statements beginning with the year ended December 31, 2013. Representatives of PricewaterhouseCoopers LLP are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

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

The affirmative vote of the holders of a majority of the shares present or represented by proxy and entitled to vote on the matter at the Annual Meeting will be required to ratify the selection of PricewaterhouseCoopers LLP.

PRINCIPAL ACCOUNTANT FEES AND SERVICES

The following table represents aggregate fees billed to us for the fiscal years ended December 31, 2023 and 2022 by PricewaterhouseCoopers LLP, our principal accountant.

​

All audit fees were pre-approved by the Audit Committee.

PRE-APPROVAL POLICIES AND PROCEDURES

The Audit Committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by our independent registered public accounting firm, PricewaterhouseCoopers LLP. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditor or on an individual, explicit, case-by-case basis before the independent auditor is engaged to provide each service. The pre-approval of services may be delegated to one or more of the Audit Committee’s members, but the decision must be reported to the full Audit Committee at its next scheduled meeting.

THE BOARD OF DIRECTORS RECOMMENDS

EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION AND ANALYSIS

Introduction

This Compensation Discussion and Analysis section of our proxy statement provides our stockholders with an explanation of our compensation philosophy, program, processes, decisions, and other relevant information related to our named executive officers (“NEOs”). Our NEOs for the year ended December 31, 2023 were:

Executive Summary

Our 2023 Business Performance

We accomplished several important goals in 2023 that relate to our overall corporate mission and strategy of developing novel drug candidates for immuno-inflammatory diseases:

2023 Say on Pay Vote

At the 2023 annual meeting of stockholders, our stockholders approved the compensation of our NEOs on an advisory basis, with approximately 98% of the votes cast “For” such approval. The Compensation Committee interpreted stockholder approval of the executive compensation program at such a level as indicating that a substantial majority of stockholders view our executive compensation program, plan design and governance as continuing to be well aligned with our stockholders, their investor experience and our business outcomes.

​

Key Compensation Decisions and Actions

Our Compensation Committee took the following actions related to 2023 NEO compensation:

​

​

Key Compensation Governance Attributes

Our Compensation Committee believes that a sound compensation program is grounded in key governance practices and processes that align with our compensation philosophy and objectives. A summary of these key features includes:

​

Approach to Compensation

Compensation Philosophy

Our executive compensation program is based on supporting our overall mission to develop novel, small molecule therapies to help patients with immuno-inflammatory diseases for which satisfactory treatment options are not available. We emphasize the following values for our employees:

​

Our compensation program is designed to attract, retain and motivate our NEOs by:

We accomplish these goals through a total view of compensation that covers multiple compensation elements including but not limited to base salary, cash- and equity-based incentives, and health and welfare benefits.

In setting NEO compensation, we consider compensation for comparable positions in the market, the historical compensation levels of our executives, individual performance as compared to our expectations and objectives, our desire

27

​

to motivate our employees to achieve short- and long-term results that are in the best interests of our stockholders and a long-term commitment to our company. We do not target a specific competitive position or a specific mix of compensation among base salary, bonus or long-term incentives; however, we do deliver a majority of compensation through long-term incentives.

Process and Roles

We review compensation annually for our NEOs, and in some cases more frequently as deemed appropriate. The various roles that contribute to our decisions and actions each year are as follows:

The Compensation Committee. The Compensation Committee is responsible for establishing and overseeing our executive compensation program. Specific responsibilities of the Compensation Committee are described in this proxy statement under “Information Regarding Committees of the Board of Directors—Compensation Committee.” Our Compensation Committee typically reviews and discusses management’s proposed compensation with the Chief Executive Officer for all executives other than the Chief Executive Officer. Based on those discussions and its discretion, the Compensation Committee then recommends the compensation for each NEO. Our Compensation Committee, without members of management present, discusses and ultimately approves the compensation of our executive officers.

Role of our Chief Executive Officer and other Management Members. Our Chief Executive Officer evaluates and reviews with the Compensation Committee the individual performance and contributions of each of the other NEOs and makes recommendations to the Compensation Committee regarding base salary, and short- and long-term incentive awards. The Compensation Committee reviews and considers such recommendations, but ultimately retains full discretion and authority over the final compensation decisions for the NEOs. Our Chief Executive Officer also recommends the Company performance objectives that are used to determine bonus amounts and consults with select members of management in the development of the goals. The Compensation Committee may request that certain executives attend portions of Compensation Committee meetings based on the topics being covered and their respective areas of expertise. NEO compensation decisions are made in executive session without the respective NEOs present.

Role of our Independent Compensation Consultant. In 2023, the Compensation Committee retained Pearl Meyer, a compensation consulting firm, to evaluate and make recommendations with respect to our executive compensation program. Pearl Meyer’s role included assisting the Compensation Committee with the selection of a peer group of companies for comparison purposes, an analysis of our existing executive compensation, the design of our long-term incentive program, an analysis of our director compensation policy, sharing new developments in areas that fall within the Compensation Committee’s jurisdiction, and advising the Compensation Committee as appropriate. The consultant serves at the pleasure of the Compensation Committee, and the consultant’s fees are approved by the Compensation Committee.

Use of Market Data

The Compensation Committee makes use of market data in making its decisions. One of these references is compensation market data derived from other comparable public companies. In September 2022, Pearl Meyer developed a peer group for use in evaluating the competitiveness of NEO compensation arrangements. The group consisted of 24 companies that were comparable to ours at that time. The key criteria used to arrive at the selected companies was as follows:

​

​

​

28

​

In September 2022, the Compensation Committee approved the following peer group, which such group was used by the Compensation Committee in connection with making compensation decisions for 2023:

​

In December 2023, Pearl Meyer again reviewed the peer group of companies for continued appropriateness. The criteria used to develop this peer group was similar to the previous year, adjusted for our change in market capitalization and anticipated operating changes. It also included new criteria based on therapeutic focus and cash balance. This criterion resulted in the following peer group of 20 companies used to make compensation decisions for 2024:

​

From time to time, the Compensation Committee also will make use of industry and size specific survey data to benchmark compensation levels or program practices. Typically, this survey data is used when the peer group disclosures do not contain the type of information being researched or have inadequate sample sizes for benchmarking purposes.

Other Information Used in Decision-Making Process

As part of its deliberations, the Compensation Committee reviews and considers, as appropriate, materials such as financial reports and budgets, tax and accounting information, executive stock ownership information, stock performance data, analyses of historical executive compensation levels and current Company-wide compensation levels and recommendations of the Compensation Committee’s compensation consultant.

Compensation Programs and Decisions

Overview

Compensation for our NEOs is comprised primarily of the following four main components:

​

Each of these key elements is further described below, along with the key decisions made for the 2023 plan year.

​

29

​

Annual Base Salary

Base salaries are determined by the Compensation Committee for each NEO. The Compensation Committee considers each NEO’s experience, expertise and performance, market compensation levels for similar positions, recommendations from the Chief Executive Officer (for all NEOs except himself), and recommendations from Pearl Meyer in making decisions regarding salary levels.

​

The following table presents the annual base salaries for each of our NEOs for 2022 and 2023:

Annual Bonus (Non-Equity Incentive Plan Compensation)

We seek to motivate and reward our executives for achievements relative to our corporate goals and expectations, and with respect to our NEOs other than the Chief Executive Officer, their respective individual goals, for each fiscal year.

The actual annual bonus paid, if any, is calculated by multiplying the NEO’s annual base salary, target bonus percentage, the percentage attainment of the corporate goals established by the Board for such year, and for our NEOs other than the Chief Executive Officer, the percentage attainment of the individual goals established by our Chief Executive Officer. The Compensation Committee is not required to determine bonuses based on this exact formula and reserves the right to consider other factors and adjust bonus amounts accordingly.

For 2023, the bonus funding factor was weighted 75% for corporate goals and 25% for individual goals for all NEOs other than our Chief Executive Officer, whose bonus funding was 100% dependent on the achievement of corporate goals.

The Compensation Committee reviews our performance against our goals and approves the extent to which we achieved each of our corporate goals and, with the input of our Chief Executive Officer, individual performance, as applicable, and, for each NEO, the amount of the bonus awarded.

​

​

​

The following chart depicts the structure of our annual bonus program for 2023:

​

Our Compensation Committee established the following target bonus opportunities for each NEO for 2023 that reflected the individual’s role and also took into consideration target bonuses among executives at peer companies:

In early 2023, our Compensation Committee approved our 2023 corporate performance goals (which comprise the corporate funding factor used to calculate the bonus funding factor). These goals were divided into two primary categories that the Compensation Committee believed were critical to achieving the Company’s mission: (a) research and development goals, which together comprised 85% of the overall corporate performance target score, and (b) other corporate goals, which comprised 15% of the overall corporate performance target score. These two categories of objectives included specific deliverables, described below, with differing weightings. The Compensation Committee also approved stretch performance goals in both the research and development and other corporate categories that, if earned, could increase the overall funding of the bonus plan up to a maximum of 140% of the corporate performance target score. The plan goals were generally intended to be measured over one year but could be accomplished at various times during the year. For each corporate goal described below, partial credit could be given by the Compensation Committee based on the actual level of achievement. We established goals designed to drive corporate performance that we believed were challenging but also achievable.

​

​

​

​

​

​

​

In late 2023, the Compensation Committee evaluated the level of achievement for the 2023 corporate performance goals. The following chart provides a summary of the corporate goals for 2023 and resulting assessment of achievement:

​
Our research and development goals included various clinical development milestones, including advancing zunsemetinib through a Phase 2b clinical trial in subjects with rheumatoid arthritis (“RA”), a Phase 2a clinical trial in subjects with psoriatic arthritis, and a Phase 2a clinical trial in subjects with hidradenitis suppurativa (“HS”), advancing ATI-1777 through a Phase 2b clinical trial in subjects with atopic dermatitis, advancing ATI-2138 through a Phase 1 MAD study and initiating Phase 2 development activities, and advancing ATI-2231 through IND submission and initiating a Phase 1 clinical trial; various preclinical development goals; and various discovery, contract research organization (“CRO”) and other research and development targets, including advancing discovery activities with respect to our pipeline and increasing our CRO business revenue. The clinical development objectives comprised the largest weighting within this category. The research and development stretch objectives related to more advanced development or additional development of our clinical, preclinical and discovery programs and additional goals related to our CRO business.

In assessing our overall level of achievement, the Compensation Committee considered, among other things, the completion of our Phase 2 trials of zunsemetinib for HS and RA, the completion of the Phase 1 MAD trial of ATI-2138, the submission of the IND for ATI-2231 and initiation of Phase 1 activities, and the progression of our preclinical programs and discovery pipeline. The Compensation Committee concluded that partial credit for our research and development goals was warranted given that we had not achieved certain clinical development objectives and our zunsemetinib trials in HS and RA did not meet their primary endpoints, and we had not achieved the revenue goal for our CRO business that could have resulted in full credit. With respect to the stretch goals, the Compensation Committee considered the progress of additional development activities with respect to ATI-2231 and our drug discovery improvements. The Compensation Committee determined that partial credit for the stretch goals was warranted, but full credit was not awarded as we had not achieved some of the clinical, preclinical and discovery goals and had not achieved the revenue goal for our CRO business.

Our other corporate goals were focused in the areas of business development, financing and investor relations, as well as certain operational and compliance goals. The other corporate stretch goals related to additional business development and financing goals. In assessing our level of achievement of these goals, the Compensation Committee considered, among other things, our net proceeds of $27.5 million from sales of our common stock, the execution of an out-licensing agreement, and the broad achievement across our investor relations, operational and compliance goals. The Compensation Committee determined that no credit for the stretch goals was warranted.

In addition to the corporate performance goals described above, Dr. Manion, who was serving as our Chief Executive Officer in 2023, evaluated the individual performance of each of Mr. Balthaser, Dr. Cawkwell, Mr. Loerop and Dr. Monahan, and recommended a level of achievement to the Compensation Committee. The individual goals focused on contributions toward our corporate objectives as well as the personal qualities necessary to effectively manage a team,

32

​

solve problems and drive our business forward. Dr. Manion recommended full credit for these individual objectives, which the Compensation Committee approved.

​

Applying the corporate and individual funding factor weightings, the Compensation Committee approved the following bonus payouts for 2023:

​

* Represents 60% multiplied by 75%, the corporate funding factor for the officer.

Long-term Incentives

Long-term incentives represent a key element of our overall compensation program. This compensation element is primarily used to aid in attracting and retaining the talent we need to achieve our mission, strategies, and underlying corporate goals. Additionally, long-term incentives align the interests of our NEOs with our stockholders.

​

The Compensation Committee typically approves long-term incentive grants for NEOs at the start of their employment, and annually thereafter in connection with the annual performance review. Additionally, the Compensation Committee may periodically grant additional equity awards based on changes in job responsibility, performance and contribution, or other special circumstances.

​

For the 2023 plan year, the Compensation Committee approved both stock options and RSUs for NEOs as part of their annual long-term incentive awards. The vesting schedules for grants made in 2023 are as follows:

​

In determining annual long-term incentive grants for NEOs, the Compensation Committee reviews market data for annual long-term incentive grant levels and groups the NEOs accordingly. The market data that the Compensation Committee reviewed for the purpose of sizing equity grants included long-term incentive awards expressed as a percentage of shares of common stock outstanding, as well as grant date fair values.

In February 2023, the Compensation Committee approved the grant of stock options and RSUs to each of our NEOs who were employed with us at that time. For all NEOs, the grants were apportioned 70% to stock options and 30% to RSUs, with the number of shares underlying the RSUs being further divided by 1.5 to reflect the full value nature of the RSUs.

​

33

​

The following table sets forth the number of shares of common stock issuable upon exercise of the stock options, and the number of shares of common stock underlying the RSUs, granted to our NEOs in 2023:

​

As of December 31, 2023, our stock price was $1.05. As a result, the stock options granted that are detailed above have an intrinsic value of $0, and the RSUs granted are worth 6% of their original grant date fair value. This reduction in value supports the notion of executive pay for performance. For further analysis of our pay and performance measures, see “Pay versus Performance”.

​

Severance and Change of Control Benefits

Our NEOs are entitled to certain benefits if the executive’s employment terminates in certain circumstances or if a change of control occurs. The terms of these arrangements and the amounts payable under them are described below for each NEO under “Compensation Tables—Potential Payments Upon Termination or Change of Control.” We provide these benefits because we believe that severance protection is necessary to attract executives to join our company, as well as to help our executives focus on the best interests of the Company when performing their duties and when making strategic decisions about a potential corporate transaction or change of control.

In January 2024, we terminated the employment of Dr. Cawkwell without cause. In connection with her departure, Dr. Cawkwell became eligible to receive the severance benefits as outlined in her employment agreement as described under “Compensation Tables—Potential Payments Upon Termination or Change of Control.”

In February 2024, in connection with Dr. Manion’s departure from the Company, we entered into a separation agreement, waiver and release with Dr. Manion pursuant to which we agreed to provide him the same severance benefits as if he were terminated without cause under his employment agreement as described under “Compensation Tables—Potential Payments Upon Termination or Change of Control.”

Benefits

We maintain a tax-qualified retirement plan (our 401(k) plan) that provides eligible U.S. employees with an opportunity to save for retirement on a tax advantaged basis, up to limits prescribed by applicable law. Currently, we match each eligible employee’s contributions up to 4% of total eligible compensation. Employees are immediately and fully vested in their contributions and our matching contribution.

Our NEOs are eligible to participate in all benefit plans offered to our employees, including our medical, dental, vision, group life and disability insurance plans. Our NEOs accrue more vacation time each pay period than other employees. We do not otherwise provide perquisites or personal benefits to our NEOs.

Prohibition on Hedging and Pledging

Our insider trading policy prohibits directors, officers, and other employees from engaging in short sales, transactions in put or call options, hedging transactions, margin accounts, pledging or other inherently speculative transactions with respect to our stock at any time.

​

​

Tax and Accounting Considerations

The Compensation Committee and management consider individual and corporate tax consequences, as well as the accounting impact, of the compensation plans prior to making changes.

Under Section 162(m) of the Internal Revenue Code of 1986, as amended, a company will generally not be entitled to a tax deduction for individual compensation over $1 million that is paid to certain executive officers. Although the Compensation Committee will continue to consider tax implications as one factor in determining executive compensation, the Compensation Committee also looks at other factors in making its decisions and retains the flexibility to provide compensation for the Company’s named executive officers in a manner consistent with the goals of the Company’s executive compensation program and the best interests of the Company and its stockholders, which may include providing for compensation that is not deductible by the Company due to the deduction limit under Section 162(m).

We account for equity compensation paid to our employees under the Financial Accounting Standards Board Accounting Standards Codification Topic 718, or ASC 718, which requires us to estimate and record an expense over the service period of the equity award. Our cash compensation is recorded as an expense over the period the compensation is earned. The accounting impact is one of many factors that the Compensation Committee considers in determining the structure and size of our executive compensation programs.

2024 Compensation Actions

The Compensation Committee or Board approved the following items in early 2024 related to NEO compensation. The compensation tables provided below do not take into account any compensation changes made in 2024, but this information is being provided as supplemental disclosure to aid in understanding our recent compensation-related activities.

35

​

Clawback Policy

In October 2023, in order to comply with SEC rules promulgated under Section 10D-1 of the Exchange Act and Nasdaq listing standards, the Compensation Committee adopted and recommended to the Board the Company’s Incentive Compensation Recoupment Policy, which the Board adopted in November 2023. Under the Incentive Compensation Recoupment Policy, in the event of an accounting restatement, the Compensation Committee, as the committee of the Board responsible for administering the policy, is authorized to recover certain incentive-based compensation paid to an executive officer of the Company on or after October 2, 2023 to the extent such incentive-based compensation was erroneously paid on the basis of financial results in respect of any of our three most recently completed fiscal years preceding the restatement.

Additionally, as a public company, if we are required to restate our financial results due to our material noncompliance with any financial reporting requirements under the federal securities laws as a result of misconduct, the CEO and CFO may be legally required to reimburse our Company for any bonus or other incentive-based or equity-based compensation they receive in accordance with the provisions of section 304 of the Sarbanes-Oxley Act of 2002.

Compensation Risk Assessment

The Compensation Committee reviews our compensation program, including compensation levels, designs, practices, and policies to understand if there are any areas that are likely to promote excessive risk-taking or create risks that have a material adverse effect on the Company. Based on the review, we believe that, through a combination of risk-mitigating features and incentives guided by relevant market practices and Company-wide goals, our compensation policies, programs, and practices do not create risks that are reasonably likely to have a material adverse effect on the Company. The following features are noted as strong mitigating features:
