PROXY STATEMENT
FOR THE 2024 ANNUAL MEETING OF STOCKHOLDERS
June 10, 2024
QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING

When are this Proxy Statement and the accompanying materials scheduled to be sent to stockholders?
We have elected to provide access to our proxy materials to our stockholders via the Internet. Accordingly, on or about April 29, 2024, we will begin mailing the Notice of Availability. Our proxy materials, including the Notice of the 2024 Annual Meeting of Stockholders, this Proxy Statement and the accompanying proxy card or, for shares held in street name (i.e., held for your account by a broker, bank or other nominee), a voting instruction form, and the 2023 Annual Report to Stockholders (the “2023 Annual Report”), will be mailed or made available to stockholders on the Internet on or about the same date.

Why did I receive a notice regarding the availability of proxy materials on the Internet?
Pursuant to rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy materials over the Internet. Accordingly, we have sent you a Notice of Internet Availability of Proxy Materials (the “Notice”) because the Board of Directors (the “Board”) of X4 Pharmaceuticals, Inc. (sometimes referred to as the “Company” or “X4”) is soliciting your proxy to vote at the 2024 Annual Meeting of Stockholders (the “Annual Meeting”), including at any adjournments or postponements of the Annual Meeting. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the internet or to request a printed copy may be found in the Notice.

Will I receive any other proxy materials by mail?
We may elect, in our discretion, to send you a proxy card, along with a second Notice, on or after ten calendar days have passed since our first mailing of the Notice.
How do I attend the Annual Meeting?
The Annual Meeting will be held in person on Monday, June 10, 2024 at 12:00 p.m. Eastern Time at the offices of Goodwin Procter LLP, 100 Northern Avenue, 17th Floor, Boston, Massachusetts 02210. Directions to the Annual Meeting may be found at https://materials.proxyvote.com. Information on how to vote in person at the Annual Meeting is discussed below.
Who can vote at the Annual Meeting?
Only stockholders of record at the close of business on April 15, 2024 will be entitled to vote at the Annual Meeting. On this record date, there were 167,937,781 shares of common stock outstanding and entitled to vote. A list of stockholders entitled to vote at the Annual Meeting will be available at our principal executive offices for examination during normal business hours by any stockholder for any purpose germane to the Annual Meeting for a period of ten days ending the day prior to the Annual Meeting.
 
Stockholder of Record: Shares Registered in Your Name
If on April 15, 2024, your shares were registered directly in your name with our transfer agent, Computershare Trust Company, N.A., then you are a stockholder of record. As a stockholder of record, you may vote in person at the Annual Meeting or vote by proxy prior to the Annual Meeting. Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy electronically through the Internet, over the telephone or by completing and returning a printed proxy card that you may request or that we may elect to deliver at a later time to ensure your vote is counted.
Beneficial Owner: Shares Registered in the Name of a Broker or Bank
If on April 15, 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 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. However, since you are not the stockholder of record, you may not vote your shares in person at the Annual Meeting unless you request and obtain a valid proxy from your broker, bank or other agent.

What am I voting on?

There are three matters scheduled for a vote:
Election of three (3) directors to hold office until the 2027 Annual Meeting of Stockholders (Proposal 1);
Ratification of selection by the Audit Committee of the Board of Directors of PricewaterhouseCoopers LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024 (Proposal 2); and
Non-binding advisory “say-on-pay” vote on our named executive officer compensation (Proposal 3);
 

What if another matter is properly brought before the Annual 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?
With respect to Proposal 1, you may either vote “FOR ALL” the nominees to the Board, “WITHHOLD ALL” for the nominees, or you may vote “FOR ALL EXCEPT” any nominee you specify. With respect to Proposals 2 and 3, you may vote “FOR” or “AGAINST” or abstain from voting.
The procedures for voting are as follows:
Stockholder of Record: Shares Registered in Your Name
If you are a stockholder of record, you may vote in person at the Annual Meeting, vote by proxy through the Internet, vote by proxy over the telephone, or vote by proxy 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 Annual Meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the Annual Meeting and vote in person even if you have already voted by proxy.

To vote in person, come to the Annual Meeting and we will give you a ballot when you arrive.
To vote through the Internet before the Annual Meeting, go to www.proxyvote.com to complete an electronic proxy card. You will be asked to provide the 16-digit control number from the Notice. Your Internet vote must be received by 11:59 p.m., Eastern Time, on June 9, 2024 to be counted.
To vote over the telephone from a location in the United States, dial toll-free 1-800-690-6903 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the control number from the Notice. Your telephone vote must be received by 11:59 p.m., Eastern Time, on June 9, 2024 to be counted.
To vote by using a printed proxy card that may be delivered to you, simply complete, sign and date the proxy card and return it promptly in the envelope provided. If you return your signed proxy card to us before the Annual Meeting, we will vote your shares as you direct.
 

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 voting instructions in the Notice to ensure that your vote is counted. To vote in person at the Annual Meeting, you must obtain a valid proxy from your broker, bank or other agent. Follow the instructions from your broker, bank or other agent included with these proxy materials, or contact that organization to request a proxy form.

We provide Internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your Internet access, such as usage charges from internet access providers and telephone companies.
 
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 as of April 15, 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, through the Internet or in person at 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 each nominee for director, “FOR” the ratification of the selection of our independent registered public accounting firm, and “FOR” the non-binding advisory vote on “say-on-pay”. If any other matter is properly presented at the Annual 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, each of Proposals 1 and 3 are considered to be “non-routine” under NYSE rules meaning that your broker may not vote your shares on this proposal in the absence of your voting instructions. However, Proposal 2 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 2. Accordingly, if you own shares through a nominee, such as a broker, bank or other agent, please be sure to instruct your nominee how to vote to ensure that your vote is counted on all of the proposals.
If you are 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.
Who is paying for this proxy solicitation?
We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees may also solicit proxies in person, 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?
If you receive more than one Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on each of 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 Annual Meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:
 
  You may submit another properly completed proxy card with a later date (which automatically revokes the earlier proxy).
 
  You may grant a subsequent proxy by telephone or through the Internet.
 
  
You may send a timely written notice that you are revoking your proxy to our Corporate Secretary at 61 North Beacon Street, 4th Floor, Boston, Massachusetts 02134.
 
  You may attend the Annual Meeting and vote in person. Simply attending the Annual Meeting will not, by itself, revoke your proxy.
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 your broker, bank or other agent.


When are stockholder proposals and director nominations 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 30, 2024, to our Corporate Secretary, c/o X4 Pharmaceuticals, Inc., 61 North Beacon Street, 4th Floor, Boston, Massachusetts 02134.
 
Our bylaws also establish an advance notice procedure if you wish to present a proposal (including a director nomination) before an annual meeting of stockholders but you are not requesting that your proposal or nomination be included in next year’s proxy materials. To be timely for our 2025 Annual Meeting of Stockholders, our Corporate Secretary must receive the written notice at our principal executive offices not later than the close of business on March 12, 2025 nor earlier than the close of business on February 10, 2025. However, if we hold our 2025 Annual Meeting of Stockholders more than 30 days before or 60 days after June 10, 2025 (the one-year anniversary date of the 2024 Annual Meeting of Stockholders), then timely notice of a stockholder proposal that is not intended to be included in our Proxy Statement must be received not earlier than the close of business on the 120th day prior to the 2025 Annual Meeting of Stockholders and not later than the close of business on the later of (a) the 90th day prior to the 2025 Annual Meeting of Stockholders and (b) the 10th day following the day on which the one of the following first occurs: (i) mailing of notice of the date of the 2024 Annual Meeting of Stockholders and (ii) the first public announcement of the date of the 2025 Annual Meeting of Stockholders. You are also advised to review our bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations. In addition, to comply with the SEC’s new universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice by the same deadline noted herein and also comply with the additional requirements of Rule 14a-19(b).

How are votes counted?
Each holder of common stock is entitled to one vote for each share held by such stockholder as of the record date on each matter to come before the Annual Meeting, including the election of a director. Votes cast during the Annual Meeting or by proxy by mail, via the Internet or by telephone will be tabulated by the inspector of election appointed for the Annual Meeting, who will also determine whether a quorum is present.

Under our bylaws, any proposal, other than an election of directors, is decided by a majority of the votes properly cast for and against such proposal, except where a larger vote is required by law or by our certificate of incorporation or bylaws. Abstentions and broker “non-votes” are not included in the tabulation of the voting results on any such proposal and, therefore, do not have an impact on such proposals. A broker “non-vote” occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item, and has not received instructions from the beneficial owner.
Votes will be counted by the inspector of election appointed for the Annual Meeting, who will separately count, for the proposal to elect directors (Proposal 1), votes “For,” “Withhold” and broker non-vote, with respect to Proposals 2 and 3, votes “For,” “Against” and abstentions. Abstentions and broker non-votes for Proposals 2 and 3 will have no effect and will not be counted towards the vote total. Votes withheld and broker non-votes on Proposal 1 will have no effect and will not be counted towards the vote total for this proposal.
What are “broker non-votes”?
As discussed above, when a beneficial owner of shares held in “street name” does not give voting instructions to his or her broker, bank or other securities intermediary holding his or her shares as to how to vote on matters deemed to be “non-routine” under NYSE rules, the broker, bank or other such agent cannot vote the shares. These unvoted shares are counted as “broker non-votes.” Each of Proposals 1 and 3 is considered to be “non-routine” under NYSE rules and we therefore expect broker non-votes to exist in connection with that proposal.
As a reminder, if you are 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.
 

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.

No effectNo effect
(1) Proposal 2 is considered to be a “routine” matter under NYSE rules. Accordingly, if you hold your shares in street name and do not provide voting instructions to your broker, bank or other agent that holds your shares, your broker, bank or other agent has discretionary authority under NYSE rules to vote your shares on this proposal.

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 in voting power of the outstanding shares entitled to vote are present at the Annual Meeting in person or represented by proxy. On the record date, there were 167,937,781 shares outstanding and entitled to vote. Thus, the holders of 83,968,892 shares must be present in person or represented by proxy at the Annual Meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person at the Annual Meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the holders of a majority of shares present at the Annual Meeting in person 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 Annual 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 eight members. There are three directors in the class whose term of office expires at our Annual Meeting: David McGirr, M.B.A., Paula Ragan, Ph.D., and Michael S. Wzyga. If elected at the Annual Meeting, each of these nominees would serve until the 2027 annual meeting and until his or her successor has been duly elected and qualified, or, if sooner, until the director’s death, resignation or removal. It is our policy that all directors and nominees for director make every effort to attend the Annual Meeting. All of the then-serving directors attended the 2023 Annual Meeting of stockholders.
Vote Required
Directors are elected by a plurality of the votes of the holders of shares present in person or by remote communication, as applicable, or represented by proxy and entitled to vote on the election of directors. Accordingly, the three 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 three 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 will instead be voted for the election of a substitute nominee proposed by us. Each person nominated for election has agreed to serve if elected. We have no reason to believe that any nominee will be unable to serve.
Director Nominees and Continuing Directors
The following is a brief biography and the ages of each nominee and each director whose term will continue after the Annual Meeting, and a discussion of the specific 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, as of the date of this Proxy Statement.
There are no family relationships between or among any of our directors or nominees. There is no arrangement or understanding between any of our directors or nominees and any other person or persons pursuant to which he or she is to be selected as a director or nominee.
There are no legal proceedings to which any of our directors is a party adverse to us or any of our subsidiaries or in which any such person has a material interest adverse to us or any of our subsidiaries.

Nominees for Election as a Class I Directors Continuing in Office Until the 2027 Annual Meeting of Stockholders

David McGirr, M.B.A.age 69, became a member of the board of directors of Arsanis, Inc. in September 2017 and continues to serve as a member of our Board upon the completion of our merger, between Arsanis, Inc. and the Company, in March 2019. From March 2013 until June 2014, Mr. McGirr was Senior Advisor to the chief executive officer of Cubist Pharmaceuticals, Inc., a biopharmaceutical company where he also served as Senior Vice President and Chief Financial Officer from November 2002 to March 2013. Prior to joining Cubist in 2002, Mr. McGirr was the President and Chief Operating Officer of Hippo Inc., a venture-financed internet technology company. From 1996 to 1999, he was the President of GAB Robins North America, Inc., a risk management company, serving also as Chief Executive Officer from 1997 to 1999.

6


December 2013 to January 2018 and Menlo Therapeutics Inc., a publicly traded biopharmaceutical company, from November 2017 until its merger with Foamix Pharmaceuticals, Ltd., another publicly traded biopharmaceutical company, in March 2019. Mr. McGirr received a B.Sc. in Civil Engineering from the University of Glasgow and received an M.B.A. from The Wharton School at the University of Pennsylvania. We believe that Mr. McGirr’s extensive experience with public and private pharmaceutical companies provides him with the qualifications and skills to serve on our Board.

Paula Ragan, Ph.D., age 54, has served as our President, Chief Executive Officer, Secretary and a member of our Board since July 2014.

Other professional roles include business roles at Hydra Biosciences, Oscient Corporation and Celera Corporation. Dr. Ragan received her B.S. from Tufts University and her Ph.D. from Massachusetts Institute of Technology and completed post-doctoral studies at Harvard Medical School. We believe that Dr. Ragan’s perspective and experience as our President and Chief Executive Officer, which provides the Board with historic knowledge, operational expertise and continuity, provides her with the qualifications and skills to serve on our Board.

Michael S. Wyzga, age 69, became a member of the board of directors of X4 Pharmaceuticals, Inc., a private company, in July 2018 and continues to serve as a member of our Board and our Chairman following the completion of the Merger in March 2019. Mr. Wyzga is currently the President of MSW Consulting Inc., a strategic consulting group focused in the life sciences area.

Prior to that, Mr. Wyzga served in various senior management positions at Genzyme Corporation, a publicly traded global biotechnology company. Mr. Wyzga joined Genzyme in February 1998 and most recently served as Executive Vice President, Finance from May 2003 until November 2011 and as Chief Financial Officer from July 1999 until November 2011.

He received an M.B.A. from Providence College and a B.S. from Suffolk University. We believe that Mr. Wyzga’s senior management experience at biopharmaceutical and biotechnology companies, his current and past experience on boards of directors of public companies, and his financial expertise qualify him to serve as a member of our Board.

We believe that Mr. Aliski’s experience, in both consulting and operational roles, with life sciences companies focused on orphan diseases, as well as his public company board experience, qualify him to serve on our Board.

Bridger, Ph.D., age 61, became a member of the board of directors of X4 Pharmaceuticals, Inc., a private company, in October 2018 and continues to serve as a member of our Board upon the completion of our merger, between Arsanis, Inc. and the Company, in March 2019.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE
INDEPENDENCE OF THE BOARD OF DIRECTORS
As required under the 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 of Directors. The Board consults with its 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 the Company, its senior management and its independent auditors, the Board has affirmatively determined that the following six directors are independent directors within the meaning of the applicable Nasdaq listing standards: Mr. Aliski, Ms. de Craecker, Ms. Lawton, Mr. McGirr, Mr. Wyzga and R. Keith Woods. In making this determination, the Board found that none of these directors or nominees for director had a material or other disqualifying relationship with the Company. Dr. Ragan is employed by us and is therefore not independent under Nasdaq listing standards. Dr. Bridger has previously provided us with consulting services in the past pursuant to a consulting agreement that was terminated in January 2023 and Dr. Stewart is currently providing consulting services to us pursuant to a consulting agreement. Therefore, neither Dr. Bridger nor Dr. Stewart are independent under the Nasdaq listing standards. See “Transactions with Related Persons and Indemnification – Certain Related-Person Transactions.”
BOARD LEADERSHIP STRUCTURE
The Board has an independent Chairman, Mr. Wyzga, who has authority, among other things, to call and preside over Board meetings, including meetings of the independent directors, to set meeting agendas and to determine materials to be distributed to the Board. Accordingly, the Chairman has substantial ability to shape the work of the Board. We believe that separation of the positions of Chairman and Chief Executive Officer reinforces the independence of the Board in its oversight of our business and affairs. Our Board also recognizes the full-time, effort and energy that our Chief Executive Officer devotes to her position in the current business environment. In addition, we believe that having an independent Chairman creates an environment that is more conducive to objective evaluation, increasing management accountability and improving the ability of the Board to assess management’s capacity to act in the best interests of our Company and our stockholders. As a result, we believe that having an independent Chairman can enhance the effectiveness of the Board as a whole.
ROLE OF THE BOARD IN RISK OVERSIGHT
One of the Board’s key functions is informed oversight of our 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. For example, in determining whether and under what circumstances we will engage in financing transactions or enter into licensing, collaboration or similar arrangements, the Board is involved in our management of risks related to our financial condition or of the risks inherent in drug development and commercialization. As part of its oversight, our Board receives reports by each committee chair regarding the committee’s considerations and actions. In particular, the Audit Committee is responsible for discussing the adequacy of our risk management activities with management and our independent registered public accounting firm. The Audit Committee’s primary emphasis is managing our financial risk exposures, including our internal control over financial reporting. The Audit Committee also monitors compliance with legal and regulatory requirements and considers and approves or disapproves any related person transactions. In addition, the Compensation Committee is responsible for considering whether our compensation programs and practices are reasonably likely to have a material adverse effect on us. The Nominating and Corporate Governance Committee assists the Board by overseeing and evaluating programs and risks associated with Board organization, membership and structure, and corporate governance.
At each of its meetings, the Board receives business updates from various members of management. These updates may identify matters that have emerged within that member of management’s scope of responsibility that involve operational, financial, legal or regulatory risks and, in these cases, the Board provides guidance to management. Our Board believes that full and open communication between management and the Board is essential for effective risk management and oversight.
In carrying out their risk oversight functions, the Board and its committees routinely request and review management updates, reports from the independent auditors and legal and regulatory advice from outside experts, as appropriate, to assist in discerning and managing important risks that may be faced by us. The Board is committed to continuing to ensure and evolve its risk oversight practices as appropriate given the stage of our evolution as a late-stage clinical biopharmaceutical company and the fast-paced changes of the life sciences industry.

MEETINGS OF THE BOARD OF DIRECTORS
The Board met 8 times during the last fiscal year. Each of our incumbent Board members 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 the last fiscal year for which he or she was a director or committee member.


INFORMATION REGARDING COMMITTEES OF THE BOARD OF DIRECTORS
The Board has three standing committees: an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. Each of these committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities. The composition and function of each of these committees are described below.
Audit Committee
The Audit Committee is currently composed of three members: Mr. McGirr (chair), Ms. Lawton and Mr. Wyzga. The Audit Committee met four times during 2023. The Board has adopted a written Audit Committee charter that is available to stockholders on our website at http://investors.x4pharma.com/.
The Audit Committee established by the Board in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), to oversee our corporate accounting and financial reporting processes and audits of our financial statements. For this purpose, the Audit Committee performs several functions. The Audit Committee:
 
  appoints, evaluates, retains, and when necessary, terminates the engagement of the independent auditors;
  oversees the independent auditor and approves the compensation of the independence auditor;
  reviews and approves the retention of the independent auditors to perform any proposed permissible non-audit services;
  oversees the work of the independent auditor, including resolution of disagreements between our management and the independent auditor regarding financial reporting;
  reviews our annual audited financial statements and quarterly financial statements with management and the independent auditor, including our disclosures under “Management’s Discussion and Analysis of Financial Condition and Results of Operations;”
  discusses the type and presentation of information to be disclosed in our earnings releases;
  coordinates the Board’s oversight of our internal control over financial reporting, disclosure procedures, cybersecurity and technology planning, and code of business conduct and ethics;
  discusses our policies with respect to risk assessment and risk management, including guidelines and policies to govern the process by which our exposure to risk is handled;
  establishes procedures, as required under applicable law, for the receipt, retention and treatment of complaints received by us regarding accounting, internal accounting controls or auditing matters and the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters;
  reviews our policies and procedures for reviewing and approving related person transactions;
  oversees the work of the internal auditors and internal audit functions, including evaluating whether the Company requires an internal audit function in order to improve in the oversight of the integrity of the Company’s financial statements, the Company’s compliance with legal and regulatory requirements, and the Company’s overall audit function; and
11


  oversees and controls the Company’s cybersecurity policies and guidelines to prevent, detect, and respond to cyber incidents or data breaches involving the Company’s products, services, data, information systems, and business operations and reviews the effectiveness of the Company’s cybersecurity programs and its practices for identifying, assessing, and mitigating cybersecurity risks across the Company’s products, services, and business operations.
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).
The Board has also determined that each of Mr. McGirr and Mr. Wyzga qualifies as an “audit committee financial expert,” as defined in applicable Security and Exchange Commission (“SEC”) rules.
Report of the Audit Committee of the Board of Directors
The material in this report is not “soliciting material,” is not deemed “filed” with the SEC and is not to be incorporated by reference in any filing of the Company under the Securities Act of 1933, as amended (the “Securities Act”) or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

The Audit Committee is appointed by our Board to assist our Board in fulfilling its oversight responsibilities with respect to (1) the integrity of the Company’s financial statements and financial reporting process and systems of internal controls regarding finance, accounting, and compliance with legal and regulatory requirements, (2) the qualifications, independence, and performance of the Company’s independent registered public accounting firm, (3) the performance of the Company’s internal audit function, if any, and (4) other matters as set forth in the charter of the audit committee approved by our board of directors.

Management is responsible for the preparation of the Company’s financial statements and the financial reporting process, including its system of internal control over financial reporting and its disclosure controls and procedures. The independent registered public accounting firm is responsible for performing an audit of the Company’s financial statements in accordance with the standards of the Public Company Accounting Oversight Board (“PCAOB”), and issuing a report thereon. The Audit Committee’s responsibility is to monitor and oversee these processes.
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 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 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.
Respectfully submitted,
David McGirr, M.B.A (Chairman)

Compensation Committee
The Compensation Committee is currently composed of three directors: Mr. Aliski (chair), Ms. de Craecker and Mr. Wyzga. All members of our Compensation Committee are independent (as independence is currently defined in Rule 5605(d)(2) of the Nasdaq Listing Rules.) The Compensation Committee met seven times during 2023. The Board has adopted a written Compensation Committee charter that is available to stockholders on our website at http://investors.x4pharma.com.
The Compensation Committee acts on behalf of the Board to review, approve or recommend for approval by the Board and oversee our compensation strategy, policies, plans and programs, including:
 
12


  
review and approval, or review and recommendation to the Board for approval, the compensation and other terms of employment or service, including salary, bonus and incentive compensation levels, deferred compensation, executive perquisites, equity compensation, severance arrangements and change-in-control benefits, of our Chief Executive Officer and the other executive officers;
  oversight of the evaluation of our senior executives, including determining the nature and frequency of the evaluation and the persons subject to the evaluation, supervising the conduct of the evaluation, and preparing assessments of the senior executives’ performance;
  review and approval or review and recommendation to the Board of our incentive-compensation and equity-based plans and approval of any tax-qualified, non-discriminatory employee benefit plans for which stockholder approval is not sought and pursuant to which options or stock may be acquired by our officers, directors, employees or consultants;
  administration of our equity compensation plans;
  review and recommendation to the Board with respect to director compensation; and
  adopt and administer a compensation recovery policy including, without limitation, a policy designed to comply with any rules or regulations adopted by the SEC and Nasdaq pursuant to Section 10D of the Exchange Act.
Compensation Committee Processes and Procedures
Our Compensation Committee is primarily responsible for determining the compensation for our executive officers. In setting base salaries and bonuses and granting equity incentive awards for our executive officers, including our NEOs, our Compensation Committee considers compensation for comparable positions in the market, the historical compensation levels of our executives, individual and corporate performance as compared to our expectations and objectives, our desire 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. As part of this process, Dr. Ragan, as our president and chief executive officer, prepares performance evaluations for the other executive officers and recommends annual salary increases, annual equity awards and cash bonuses to the Compensation Committee, which is ultimately approved by the Compensation Committee. The Compensation Committee also conducts a performance evaluation of Dr. Ragan and reviews and approves, or recommends for approval by the Board, the compensation of Dr. Ragan, including salary, bonus and incentive compensation levels; deferred compensation; executive perquisites; equity compensation; severance arrangements; change-in-control benefits and/or other forms of executive officer compensation. Dr. Ragan may not be present during voting or deliberations on her compensation or evaluation. As necessary, the Compensation Committee consults with the Board as to the achievement of corporate objectives that drive contingent compensation awards.

Our Compensation Committee has the authority to delegate authority to one or more subcommittees as it deems appropriate from time to time under the circumstances. Additionally, our Compensation Committee may delegate to one or more executive officers of the Company the power to grant options or other stock awards pursuant to our equity-based plan to employees of the Company or any subsidiary of the Company who are not directors or executive officers of the Company. Our Compensation Committee has delegated Dr. Ragan such authority, subject to certain parameters.

Our Compensation Committee has the authority to engage the services of a consulting firm or other outside advisors to assist it in designing our executive compensation programs and in making compensation decisions. We have utilized a compensation consultant, Arnosti Consulting, with expertise in the biotechnology market, to help assess executive and employee compensation and to help inform our compensation strategy. Arnosti Consulting reports directly to our Compensation Committee. Our Compensation Committee annually assesses its independence consistent with Nasdaq listing standards and concluded that the engagement of Arnosti Consulting did not raise any conflict of interest.

Nominating and Corporate Governance Committee
The Nominating and Corporate Governance Committee is current composed of three directors: Mr. Aliski (chair), Mr. McGirr, and Mr. Wyzga. 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 Rules). The Nominating and Corporate Governance Committee met three times during 2023. The Board has adopted a written Nominating and Corporate Governance Committee charter that is available to our stockholders on our website at http://investors.x4pharma.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 candidates for election to the Board, making recommendations to the Board regarding the membership of the committees of the Board (including with respect to making changes or rotation of members, the creation of additional Board committees, or changes in Committee charters), overseeing an annual self-assessment of the Board, overseeing succession planning for senior executives of the Company, and developing and recommending to the Board 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 a reputation for integrity, honesty and adherence to high ethical standards; demonstrated business acumen, experience and the ability to exercise sound judgements in matters that relate to the current and long-term objectives of the Company and a willingness and ability to contribute positively to the decision-making process of the Company; a commitment to understand the Company and its industry and to regularly attend and participate in meetings of the Board and its committees; the interest and ability to understand the sometimes conflicting interests of the various constituencies of the Company, which include stockholders, employees, customers, governmental units, creditors and the general public, and to act in the interests of all stockholders; and the ability to serve for at least three years before reaching the age of 75. The Nominating and Corporate Governance Committee also believes that candidates for director should not have, nor appear to have, a conflict of interest that would impair the candidate’s ability to represent the interests of all the Company’s stockholders and to fulfill the responsibilities of a director. 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, and the Nominating and Corporate Governance Committee has direct input from the Chairman of the Board and the Chief Executive Officer.
Our Nominating and Corporate Governance Committee has not adopted a formal diversity policy in connection with the consideration of director nominations or the selection of nominees but believes that our Board, taken as a whole, should embody a diverse set of skills, experiences and backgrounds. In this regard, the Nominating and Corporate Governance Committee will consider issues of diversity among its members in identifying and considering nominees for director, and strive where appropriate to achieve a diverse balance of backgrounds, perspectives, experience, age, gender, ethnicity and country of citizenship on our Board and its committees. The Nominating and Corporate Governance Committee does not make any particular weighting of diversity or any other characteristic in evaluating nominees and directors.
The Nominating and Corporate Governance Committee appreciates the value of thoughtful Board refreshment, and regularly identifies and considers qualities, skills and other director attributes that would enhance the composition of the Board. In the case of incumbent directors whose terms of office are set to expire, the 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. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines 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 then uses its network of contacts to compile a list of potential candidates, but 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. 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
14


Nominating and Corporate Governance Committee at the following address: c/o X4 Pharmaceuticals, Inc., 61 North Beacon Street, 4th Floor, Boston, Massachusetts 02134 at least 120 days prior to the anniversary date of the mailing of our 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 our common 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.
STOCKHOLDER COMMUNICATIONS WITH THE BOARD OF DIRECTORS
These communications will be reviewed by one or more employees of the Company designated by the Board, who will determine whether the communication should be presented to the Board. Stockholders who wish to communicate with our Board, or any individual director, may do so by sending written communications addressed to our Corporate Secretary at 61 North Beacon Street, 4th Floor, Boston, Massachusetts 02134.
Communications will be distributed to the Board, or to any individual director or directors as appropriate, depending on the facts and circumstances outlined in the communications. Items that are unrelated to the duties and responsibilities of our Board of Directors may be excluded, such as:
 
  junk mail and mass mailings;
  resumes and other forms of job inquiries;
  surveys; and
  solicitations or advertisements.
In addition, any material that is unduly hostile, threatening, or illegal in nature may be excluded, in which case it will be made available to any outside director upon request.
CODE OF ETHICS
We have adopted a Code of Business Conduct and Ethics that applies to all of our officers, directors and employees. The Code of Business Conduct and Ethics is available on our website at http://investors.x4pharma.com. If the Company makes any substantive amendments to the Code of Business Conduct and Ethics or grants any waiver from a provision of the Code of Business Conduct and Ethics to any executive officer or director, the Company will promptly disclose the nature of the amendment or waiver on its website.

HEDGING POLICY
Our Board has adopted an insider trading policy, which prohibits our employees, directors and certain consultants from engaging in hedging or monetization transactions with respect to our securities, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars, and exchange funds. In addition, our insider trading policy prohibits trading in derivative securities related to our securities, which include publicly traded call and put options, engaging in short selling of our common stock, purchasing our common stock on margin or holding it in a margin account and pledging our shares as collateral for a loan.

INCENTIVE COMPENSATION RECOUPMENT POLICY
Our board of directors adopted an Incentive Compensation Recoupment Policy effective as of October 2, 2023 (the “Incentive Compensation Recoupment Policy”), in compliance with the Nasdaq listing rules, which requires recovery from executive officers of incentive-based compensation that is earned, granted or vested based on the achievement of a financial reporting measure in the event of a required accounting restatement of previously issued financial statements. The recoverable compensation includes any compensation received after the effective date of the Incentive Compensation Recoupment Policy and in the three-year fiscal period preceding the date we were required to prepare the accounting restatement that is in excess of the amount that would have been earned, paid or vested had it been calculated based on the restated financial statements. Recovery is required regardless of fault or a covered officer’s role in the financial reporting process. The Incentive Compensation Recoupment Policy has been filed as Exhibit 97.1 to our Annual Report on Form 10-K for the year ended December 31, 2023. At no time during or after the year ended December 31, 2023, was the Company required to prepare an accounting restatement that required recovery of erroneously awarded compensation pursuant to the Incentive Compensation Recoupment Policy, nor was there, on December 31, 2023, an outstanding balance of erroneously awarded compensation to be recovered from the application of the policy to a prior restatement.

PROPOSAL 2
RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Audit Committee of the Board has selected PricewaterhouseCoopers LLP as our 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 our financial statements since 2016 and also served as our auditor when we were a private company since 2016. 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 our Bylaws nor other governing documents or law require stockholder ratification of the selection of PricewaterhouseCoopers LLP as our 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 our best interests and our stockholders.
PRINCIPAL ACCOUNTANT FEES AND SERVICES
The following table represents aggregate fees billed to us for the fiscal years ended December 31, 2023 and December 31, 2022 by PricewaterhouseCoopers LLP, our principal accountant.
 
   For the year ended
   2023  2022
Audit Fees (1)
  $943,000   $960,000 
Audit-related Fees
  —   — 
Tax Fees
  —   — 
All Other Fees (2)
  4,250   4,038 
Total Fees  $947,250   $964,038 
 
(1)Consists of fees billed for professional services provided to us in connection with the annual audit of our consolidated financial statements, the review of our quarterly condensed consolidated financial statements, as well as audit services that are normally provided by an independent registered public accounting firm in connection with statutory and regulatory filings or engagements for those fiscal years, such as statutory audits. Included in 2023 and 2022 Audit Fees are fees of $158,000 and $255,000, respectively, in connection with the filing of registration statements and issuance of comfort letters.
(2)Consists of subscription fees paid for access to online accounting research software applications and data.
All fees described above were pre-approved by the Audit Committee. There were no services that were approved by the Audit Committee pursuant to Rule 2-01(c)(7)(i)(C) (relating to the approval of a de minimis amount of non-audit services after the fact but before completion of the audit).
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. Prior to engagement of an independent registered public accounting firm for the next year’s audit, management will submit an aggregate of services expected to be rendered during that year for each of four categories of services (audit services, audit-related services, tax services and other fees) to the Audit Committee for approval. Prior to engagement, the Audit Committee pre-approves these services by category of service. The fees are budgeted, and the Audit Committee requires our independent registered public accounting firm and management to report actual fees versus the budget periodically throughout the year by category of service. During the year, circumstances may arise when it may become necessary to engage our independent registered public accounting firm for additional services not contemplated in the original pre-approval. In those instances, the Audit Committee requires
16


specific pre-approval before engaging our independent registered public accounting firm. 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 Audit Committee has determined that the rendering of services other than audit services by PricewaterhouseCoopers LLP is compatible with maintaining the principal accountant’s independence.
Vote Required
The affirmative vote of the holders of shares representing a majority of the shares present in person or by proxy and entitled to vote on this matter at the Annual Meeting will be required to ratify the selection of PricewaterhouseCoopers LLP.

PROPOSAL 3

NON-BINDING ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION

In accordance with the requirements of Section 14A of the Exchange Act (which was added by the Dodd-Frank Wall Street Reform and Consumer Protection Act, we are providing our stockholders with an opportunity to make a non-binding advisory vote on the compensation of our named executive officers, as disclosed in this Proxy Statement.

This non-binding advisory vote is commonly known as a “say-on-pay” vote and provides our stockholders with the opportunity to express their views on our executive compensation for our named executive officers for fiscal year 2023.

We urge stockholders to read the “Executive Compensation” section of this Proxy Statement, which discusses our executive compensation policies and procedures and contains tabular information and narrative discussion about our executive compensation policies and procedures and the compensation of our named executive officers.

Advisory Vote and Board Recommendation
We request stockholder approval, on a non-binding and advisory basis, of the compensation of our named executive officers as disclosed in this Proxy Statement pursuant to the SEC’s compensation disclosure rules (which disclosure includes the compensation tables and narrative disclosures that accompany the compensation tables within the Executive Compensation section of this Proxy Statement). This vote is not intended to address any specific element of compensation, but rather the overall compensation of our named executives and the compensation philosophy, policies, and practices described in this Proxy Statement. Accordingly, we ask our stockholders to vote “FOR” on the following resolution at the Annual Meeting:

“RESOLVED, that the Company’s stockholders approve, on a non-binding and advisory basis, the compensation of the named executive officers, as disclosed in the Company’s Proxy Statement for the 2024 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the compensation tables and narrative discussions that accompany the compensation tables within the Executive Compensation section of this Proxy Statement.”

The say-on-pay vote is advisory, and therefore not binding on the corporation or our Board of Directors. Although non-binding, our Board of Directors and the Compensation Committee value the opinions of our stockholders, and will carefully review and consider the voting results when making future decisions regarding our executive compensation program.

Vote Required
The affirmative vote of the holders of shares representing a majority of the shares present in person or by proxy and entitled to vote on this matter at the Annual Meeting will be required to ratify the advisory “say-on-pay” vote on executive compensation.

THE BOARD OF DIRECTORS RECOMMENDS
A VOTE “FOR” ON PROPOSAL 3.

NARRATIVE TO SUMMARY COMPENSATION TABLE
The material terms of the elements of our executive compensation program are described below.
Base Salary
Each named executive officer’s base salary is a fixed component of annual compensation for performing specific duties and functions, and has been established by our Board taking into account each individual’s role, responsibilities, skills, and experience. Effective January 1, 2023, our Board, upon the recommendation of the Compensation Committee increased Dr. Ragan’s base salary to $620,053, and increased Mr. Mostafa’s base salary to $486,192. The Compensation Committee set Dr. Arbet-Engels’s salary to $500,000 upon his commencement of employment on August 16, 2023.     

Bonus Compensation
Our annual bonus program is intended to reward our named executive officers for meeting objective or subjective individual and/or company-wide performance goals for a fiscal year. For 2023, our named executive officers received incentive compensation based upon the Board’s determination (following the recommendation of the Compensation Committee) of their respective achievement of and performance with respect to corporate objectives, which are described below, as well as their respective individual performance. Dr. Ragan’s and Mr. Mostafa’s bonus targets were 55%, and 40%, respectively, of their annual base salaries. Pursuant to Dr. Arbet-Engels’s employment agreement, he received the Arbet-Engels 2023 Bonus and the Signing Bonus, in each case subject to repayment in certain conditions, as further described above in the Summary Compensation Table.

In February 2024, the Compensation Committee completed an evaluation of the Company’s overall performance for 2023 and the named executive officers’ respective contributions in achieving this performance. The Compensation Committee’s review was based on company performance against corporate objectives, as well as individual performance against individual goals established by the Compensation Committee. Following such review, our Board (following the recommendation of the Compensation Committee) determined that the corporate performance objectives were achieved at the 110% level. Our Board also determined that Dr. Ragan had earned 110% of her target bonus for 2023, equal to a bonus of $375,132, and Mr. Mostafa had earned approximately 110% of his target bonus for 2023, equal to a bonus of $214,000.
26


Long-Term Equity Incentives
Our equity grant program is intended to align the interests of our named executive officers with those of our stockholders and to motivate them to make important contributions to our performance. During the fiscal year ended December 31, 2023, we granted a stock option award to Dr. Arbet-Engels as an inducement to his commencement of employment with the Company and restricted stock units as annual refresh grants to Dr. Ragan and Mr. Mostafa, as described in more detail in the “Outstanding Equity Awards at Fiscal 2023 Year-End” table above.


Employment and Change in Control Arrangements
Paula Ragan, Ph.D.
On March 13, 2019, we entered into an amended and restated executive employment agreement with Dr. Ragan, which was subsequently amended on February 10, 2020 and April 15, 2020, pursuant to which Dr. Ragan agreed to continue serving as our Chief Executive Officer. Pursuant to the employment agreement, Dr. Ragan’s compensation consists of base salary at an annual rate approved by our Board or an appropriate committee thereof, an annual performance bonus as determined by our Board (provided that the target for such bonus shall be no less than 25% of Dr. Ragan’s annual base salary), employee benefits, vacation, reimbursement of ordinary and reasonable out-of-pocket expenses and coverage under our Directors’ and Officers’, or D&O, insurance policies, subject to the terms and conditions of such policies. Dr. Ragan’s 2022 base salary was $587,728, and in March 2023, Dr. Ragan’s 2023 annual base salary was retroactively increased to $620,053 (effective January 1, 2023). Subsequently, in February 2024, Dr. Ragan’s 2024 annual base salary was retroactively increased to $654,156 (effective January 1, 2024).
Pursuant to her employment agreement, if Dr. Ragan’s employment is terminated for any reason, Dr. Ragan will be entitled to receive her accrued but unpaid salary, accrued but unused vacation days, and the amount of any properly incurred expenses prior to termination not yet reimbursed and other benefits. In addition to the foregoing, if Dr. Ragan’s employment is terminated by us without cause or if Dr. Ragan resigns for good reason, each term as defined in her employment agreement, Dr. Ragan will be entitled to the following: (a) her base salary for a period of 12 months following such termination, (b) a pro-rated portion of her target annual bonus for the calendar year in which the termination occurs, payable in a lump sum, (c) so long as Dr. Ragan is eligible for coverage under our health insurance plan, elects coverage, was covered prior to termination, and elects to exercise her rights under COBRA to continue participation in such plan, we will pay an amount equal to the monthly employer contribution we pay for current employees under such plan until the earlier of 12 months from the date of Dr. Ragan’s termination, or the date Dr. Ragan is eligible to receive health benefits through another employer, and (d) Dr. Ragan will become vested in the additional number of outstanding time-based equity awards granted to Dr. Ragan by us that would have otherwise vested had Dr. Ragan remained employed for an additional 12 months after her termination date. In lieu of the foregoing, if Dr. Ragan’s employment is terminated without cause or if Dr. Ragan resigns for good reason, in either case within the one-year period following a change of control, as that term is defined in the employment agreement, Dr. Ragan will be entitled to the following, in addition to her accrued but unpaid benefits: (a) her base salary for a period of 18 months following such termination, (b) 100% of her annual bonus for the calendar year in which the termination occurs, payable in a lump sum, (c) so long as Dr. Ragan is eligible for coverage under our health insurance plan, elects coverage, was covered prior to termination, and elects to exercise her rights under COBRA to continue participation in such plan, we will pay an amount equal to the monthly employer contribution we pay for current employees under such plan until the earlier of 12 months from the date of Dr. Ragan’s termination, or the date Dr. Ragan is eligible to receive health benefits through another employer, and (d) automatic vesting in all outstanding time-based equity awards granted to Dr. Ragan by us. As a condition to receiving the foregoing severance benefits, Dr. Ragan must execute and not revoke a separation agreement in a form acceptable to us and which will include a complete release of claims and terms related to non-disparagement, non-competition, confidentiality and cooperation.

Dr. Ragan’s employment agreement also contains her agreement to continue to abide by the terms of her non-competition, non-solicitation, non-disclosure and intellectual property agreement.

In addition, Dr. Ragan’s employment agreement provides that in the event the severance and other benefits provided for or otherwise payable to Dr. Ragan constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) and are subject to the excise tax imposed by Section 4999 of the Code, we will pay either (i) Dr. Ragan’s severance benefits under the employment agreement in full or (ii) only a part of Dr. Ragan’s severance benefits under the employment agreement such that Dr. Ragan receives the largest payment possible without the imposition of the excise tax, in each case, depending upon which alternative would result in Dr. Ragan receiving the greater net after-tax payment.

401(k) Plan
We maintain a defined contribution retirement plan that provides eligible U.S. employees with an opportunity to save for retirement on a tax-advantaged basis. Eligible employees may defer eligible compensation on a pre-tax basis, up to the statutorily prescribed annual limits on contributions under the Code. Contributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participants’ directions. Employees are immediately and fully vested in their contributions.We provide a discretionary matching contribution equal to 100% of employee contributions up to a maximum of 4% of eligible compensation, as defined under the 401(k) plan. The 401(k) plan is intended to be qualified under Section 401(a) of the Code with the 401(k) plan’s related trust intended to be tax exempt under Section 501(a) of the Code. As a tax-qualified retirement plan, contributions to the 401(k) plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) plan.
Health and Welfare Benefits
All of our full-time employees, including our named executive officers, and certain of our part-time employees are eligible to participate in our health and welfare benefit plans, including our medical, dental, life and long-term disability insurance plans. Our health and welfare benefit plans do not discriminate in scope, terms or operation in favor of our executive officers.

(a)     The grant date fair value of equity awards represents the total of the amounts reported in the “Stock Awards” and/or “Option Awards” columns in the Summary Compensation Table for the applicable year.

(b)     The fair value of stock options reported for CAP purposes is estimated using a Black-Scholes option pricing model for purposes of this PVP calculation in accordance with the SEC rules. This model uses both historical data and current market data to estimate the fair value of options and requires several assumptions. The assumptions used in estimating fair value for awards granted and vesting during fiscal years 2023, 2022, and 2021 are as follows:

30



202320222021
Risk-free interest rate3.5% - 4.5%1.7% - 4.3%0.5% - 1.5%
Expected term (in years)3.00 - 6.333.0 - 4.83.2 - 3.7
Expected volatility90.8% - 99.4%94.5 % - 101.4%94.5% - 97.0%
Expected dividend yield—%—%—%

    The fair value of restricted stock units reported for CAP purposes is based on the closing market price of the Company’s common stock on the date of each vesting event and at the end of the period. The fair value of performance-based restricted stock units is based on the closing market price of the Company’s common stock on the date of each vesting event and at the end of the period and assumes that vesting is probable, consistent with the amount calculated in accordance with the provisions of ASC 718 and reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on March 21, 2024.

(4)     The dollar amounts reported represent the average of the amounts reported for our non-PEO NEOs for each corresponding year in the “Total” column of the Summary Compensation Table for such applicable year.

(5)    The Company’s total shareholder return (TSR) reflected in this column for each applicable fiscal year is calculated based on a fixed investment of $100 at the applicable measurement point on the same cumulative basis as is used in Item 201(e) of Regulation S-K.

(6)    The dollar amounts reported represent the amount of net income (or loss) reflected in the Company’s audited financial statements for the applicable year.

(1)Dr. Ragan, one of our directors who also serves as our Chief Executive Officer and President, did not receive any additional compensation for her service director. Dr. Ragan is a named executive officer and, accordingly, the compensation that we pay to Dr. Ragan is described under “2023 Summary Compensation Table” and “Narrative Disclosure to Summary Compensation Table.”
(2)The amounts reported in the “Stock Awards” column reflect the aggregate grant date fair value of restricted stock units awarded during 2023 computed in accordance with the provisions of ASC 718, which disregards any estimated forfeitures related to service-based vesting conditions for this purpose. See Note 12 to our consolidated financial statements appearing in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 filed with the SEC on March 21, 2024, regarding assumptions underlying the valuation of equity awards. The amounts reported in this column reflect the accounting expense for these restricted stock units and do not correspond to the actual economic value that may be received by our directors upon the vesting and settlement of the restricted stock units or any sale of the underlying shares of common stock.
(3)The aggregate number of shares subject to outstanding stock options held by each director listed in the table above as of December 31, 2023 was as follows: 16,281 shares for Mr. Aliski; 67,851 shares for Dr. Bridger; 12,250 for Ms. de Craecker; 12,854 for Ms. Lawton; 18,686 shares for Mr. McGirr; 26,281 shares for Dr. Stewart; and 86,605 shares for Mr. Wyzga.

(4)Dr. Stewart continued to serve as an outside director during 2023 following his transition from our interim Chief Medical Officer in July 2023 upon the Company’s hiring of Dr. Arbet-Engels as Chief Medical Officer. Dr. Stewart was an executive officer for 2023, but not a named executive officer for 2023. As such, his compensation for services as an executive officer have not been included in this table.
(5)On August 16, 2023, the Company entered into an independent contractor agreement with Dr. Stewart, pursuant to which Dr. Stewart is entitled to receive consulting fees of $64,245 for the period August 16, 2023 through September 30, 2023, and $4,237 per month thereafter until June 30, 2024.

NARRATIVE TO DIRECTOR COMPENSATION TABLE
Non-Employee Director Compensation Policy in Effect for Fiscal Year 2023
In March 2023, our Board, upon the recommendation of the Compensation Committee, approved an amendment to our non-employee director compensation policy. Prior to the amendment to our non-employee director compensation policy, the initial equity grant to non-employee directors joining the Board consisted of 13,333 restricted stock units vesting in equal annual installments on the first two anniversaries of the date of grant, subject to the non-employee director’s continued service as a director. This vesting accelerates as to 100% of the restricted stock units upon a change in control of the Company. Further, on the date of our annual meeting of stockholders, each non-employee director that had served on our Board for at least six months was eligible to receive 6,667 restricted stock units vesting in equal annual installments on the first two anniversaries of the date of grant, subject to the non-employee director’s continued service as a director, with 100% acceleration of vesting upon a change in control of the Company.

Pursuant to the amended policy, for 2023, the initial equity grant to non-employee directors joining the Board consisted of 90,000 restricted stock units vesting in equal annual installments on the first three anniversaries of the date of grant, subject to the non-employee director’s continued service as a director. This vesting accelerates as to 100% of the restricted stock upon a change in control of the Company.

Further, on the date of our annual meeting of stockholders, each non-employee director that had served on our Board for at least six months was eligible to receive 45,000 restricted stock units vesting in full on the first anniversary of the date of grant (or the date of the next annual meeting, if such meeting is earlier than the anniversary of the grant), subject to the non-employee director’s continued service as a director, with 100% acceleration of vesting upon a change in control of the Company.

33


For fiscal year 2023, we paid our non-employee directors a cash retainer for service on the Board and for service on each committee on which the director was a member. The Chairman of the Board and the Chair of each committee received higher retainers for such service. These fees are payable in arrears in four equal quarterly installments on the last day of each     quarter, provided that the amount of such payment would be prorated for any portion of such quarter that the director was not serving on the Board, on such committee or in such position. The fees paid to non-employee directors for service on the Board, for service as a Lead Independent Director and for service on each committee of the Board on which the director was a member were as follows:
 
   Annual Retainer Amount for Member (excluding Chair)  Annual Retainer Amount for Chair 
Board of Directors  $35,000  $75,000 
Audit Committee  $7,500  $15,000 
Compensation Committee  $5,000  $10,000 
Nominating and Corporate Governance Committee  $4,000  $8,000 
We also reimburse our non-employee directors for reasonable travel and other expenses incurred in connection with attending meetings of the Board and any committee of the Board of Directors on which they served.

The evergreen provides for an automatic increase in the number of shares available for issuance equal to the least of (i) 4% of the outstanding number of shares of common stock on such date and (ii) an amount determined by our Board. Any awards granted under our 2010 Special Stock Incentive Plan, as amended (the “2010 Plan”), and the Company’s 2011 Stock Incentive Plan, as amended (the “2011 Plan”), that expire, terminate or are otherwise surrendered, canceled, forfeited or repurchased by the Company are added to shares available for issuance under the 2017 Plan. No further awards may be granted under the 2010 Plan or 2011 Plan.

TRANSACTIONS WITH RELATED PERSONS AND INDEMNIFICATION
RELATED-PERSON TRANSACTIONS POLICY AND PROCEDURES
Our Board of Directors has adopted a written related person transaction policy to set forth policies and procedures for the review of any transaction, arrangement or relationship in which our company is a participant, the amount involved exceeds $120,000, and one of our executive officers, directors, director nominees or 5% stockholders, or their immediate family members, each of whom we refer to as a “related person,” has a direct or indirect material interest.
If a related person proposes to enter into such a transaction, arrangement or relationship, which we refer to as a “related party transaction,” the related person must report the proposed related person transaction to our Chief Financial officer. The policy calls for the proposed related person transaction to be reviewed and approved by our Audit Committee. Whenever practicable, the reporting, review and approval will occur prior to entry into the transaction. If advance review and approval is not practicable, Audit Committee will review and, in its discretion, may ratify the related person transaction. The policy also permits the Chair of the Audit Committee to review and, if deemed appropriate, approve proposed related person transactions that arise between Audit Committee meetings, subject to ratification by the Audit Committee at its next meeting. Any related person transactions that are ongoing in nature will be reviewed annually.
A related person transaction reviewed under this policy will be considered approved or ratified if it is authorized by the Audit Committee in accordance with the standards set forth in the policy after full disclosure of the related person’s interests in the transaction. As appropriate for the circumstances, the policy provides that the Audit Committee will review and consider:
 
  the related person’s interest in the related person transaction;
 
  the approximate dollar value of the amount involved in the related person transaction;
 
  the approximate dollar value of the amount of the related person’s interest in the transaction without regard to the amount of any profit or loss;
 
  whether the transaction was undertaken in the ordinary course of our business;
 
  whether the terms of the transaction are no less favorable to us than the terms that could have been reached with an unrelated third party;
 
  the purpose of, and the potential benefits to us of, the transaction; and
 
  any other information regarding the related person transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.
The Audit Committee may approve or ratify the related person transaction only if the Audit Committee determines that, under all of the circumstances, the transaction is in our best interests. The Audit Committee may impose any conditions on the related person transaction as it deems appropriate. The policy also provides that transactions involving compensation of executive officers will be reviewed and approved by our Compensation Committee in the manner specified in its charter.
For purposes of the policy, we refer to certain related-party transactions below in which (a) we were a participant, (b) the amount involved exceeded or will exceed $120,000 or, during such time as we qualify as a “smaller reporting company,” the lesser of (1) $120,000 or (2) 1% of the average of our total assets for the last two completed fiscal years, and (c) one or more related persons had a direct or indirect material interest. Transactions involving compensation for services provided to us by an employee, director, consultant or individual performing in a similar capacity by a related person are not covered by this policy.

CERTAIN RELATED-PERSON TRANSACTIONS
Since January 1, 2022, we have engaged in, or currently propose to engage in, the following related-party transactions. We believe that all of these transactions were on terms comparable to terms that could have been obtained from unrelated third parties.

Agreements with Directors

Gary J. Bridger, Ph.D.
On September 17, 2020, we entered into an independent contractor agreement, as amended, with Gary J. Bridger, Ph.D., pursuant to which Dr. Bridger was entitled to receive $30,000 per month and a non-qualified stock option to purchase 30,000 shares of our common stock in consideration for his performance of certain consulting services to the Company during the period from September 17, 2020 to January 1, 2023. The consulting agreement terminated in January 2023.

Murray W. Stewart, M.D.
On August 16, 2023, we entered into an independent contract agreement, as amended with Murray W. Stewart, M.D., pursuant to which Dr. Stewart is entitled to receive consultant a fee $64,245 from August 16, 2023 through September 30, 2023 and a fee of $4,237 per month until June 30, 2024. The services Dr. Stewart is to provide are completion of WHIM NDA submission and subsequent related support, chronic neutropenia related clinical strategy, support transition of new CMO and provide general clinical/medical, regulatory and other pertinent support and guidance. The consulting agreement will terminate in June 2024.

Employment Arrangements
We have entered into employment agreements with our executive officers. Each of our executive officers has entered into a written employment agreement with us that provides for payment of base salary, target annual cash incentive compensation, eligibility for employee benefit programs and potential severance benefits. For more information regarding these agreements with our named executive officers, see “Executive Compensation.”

Equity Awards Granted to Executive Officers and Directors
We have granted options to our executive officers and directors. For more information regarding the equity awards granted to our named executive officers and directors, see “Executive Compensation” and “Director Compensation for Fiscal Year 2023.”

INDEMNIFICATION
We provide indemnification for our directors and executive officers so that they will be free from undue concern about personal liability in connection with their service to us. Under our Bylaws, we are required to indemnify our directors and executive officers to the extent not prohibited under Delaware or other applicable law. We have also entered into indemnity agreements with certain officers and directors. These agreements provide, among other things, that we will indemnify the officer or director, under the circumstances and to the extent provided for in the agreement, for expenses, damages, judgments, fines and settlements he or she may be required to pay in actions or proceedings which he or she is or may be made a party by reason of his or her position as a director, officer or other agent of the Company, and otherwise to the fullest extent permitted under Delaware law and our Bylaws.

HOUSEHOLDING OF PROXY MATERIALS
The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials or other Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or other Annual Meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.
This year, a number of brokers with account holders who are X4 stockholders will be “householding” the Company’s proxy materials. A single Notice of Internet Availability of Proxy Materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications 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 Notice of Internet Availability of Proxy Materials, please notify your broker or X4. Direct your written request to X4 Pharmaceuticals, Inc., Attn: Corporate Secretary, 61 North Beacon Street, 4th Floor, Boston, MA 02134 or contact the Corporate Secretary at (857) 529-8300. Stockholders who currently receive multiple copies of the Notices of Internet Availability of Proxy Materials at their addresses and would like to request “householding” of their communications should contact their brokers.
