Notice is hereby given that the 2023 Annual Meeting of Stockholders, or Annual Meeting, of Disc Medicine, Inc., will be held on June 9, 2023 at 9:00 A.M. Eastern Time. The Annual Meeting will be a completely virtual meeting, which will be conducted by live webcast at www.virtualshareholdermeeting.com/IRON2023. You will be able to vote electronically and submit questions during the virtual meeting. You will need the 16 digit control number, which is located on the Notice of Internet Availability of Proxy Materials, or the Notice, that you received in the mail, on your proxy card, or in the instructions accompanying your proxy materials, to attend the virtual meeting. The purpose of the Annual Meeting is the following:

1.
To elect three Class II directors to our board of directors, to serve until the 2025 annual meeting of stockholders and until their successors have been duly elected and qualified, or until their earlier death, resignation or removal, and to elect three Class III directors to our board of directors, to serve until the 2026 annual meeting of stockholders and until their successors have been duly elected and qualified, or until their earlier death, resignation or removal;
2.
To ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023; and
3.
To transact any other business properly brought before the Annual Meeting or any adjournment or postponement of the Annual Meeting.

The proposal for the election of directors relates solely to the election of three Class II directors and three Class III directors nominated by the board of directors.

Only Disc Medicine, Inc. stockholders of record at the close of business on April 14, 2023, will be entitled to vote at the Annual Meeting and any adjournment or postponement thereof.

Disc Medicine, Inc. is following the Securities and Exchange Commission’s “Notice and Access” rule that allows companies to furnish their proxy materials by posting them on the Internet. As a result, we are mailing to our stockholders a Notice of Internet Availability of Proxy Materials, or the Notice, instead of a paper copy of the accompanying proxy statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, or 2022 Annual Report. The Notice contains instructions on how to access both the 2022 Annual Report and accompanying proxy statement over the Internet. This method provides our stockholders with expedited access to proxy materials, lowers the cost of printing and distribution, and reduces the environmental impact of the Annual Meeting. If you would like to receive a print version of the proxy materials, free of charge, please follow the instructions on the Notice.

Please see the “General Information” section of the proxy statement that accompanies this notice for more details regarding the logistics of the Annual Meeting.

PROXY S TATEMENT

FOR THE 2023 Annual Meeting OF STOCKHOLDERS

TO BE HELD JUNE 9, 2023

This proxy statement contains information about the 2023 Annual Meeting of Stockholders, or the Annual Meeting, of Disc Medicine, Inc., which will be held on June 9, 2023 at 9:00 A.M. Eastern Time. The Annual Meeting will be a completely virtual meeting, which will be conducted by live webcast at www.virtualshareholdermeeting.com/IRON2023. There will be no physical meeting location. You will be able to vote electronically and submit questions during the virtual meeting. You will need the 16 digit control number, which is located on the Notice of Internet Availability of Proxy Materials, or the Notice, that you received in the mail, on your proxy card, or in the instructions accompanying your proxy materials, to attend the virtual meeting. The board of directors of Disc Medicine, Inc. is using this proxy statement to solicit proxies for use at the Annual Meeting. In this proxy statement, the terms “Disc,” “Disc Medicine,” the “Company,” “we,” “us,” and “our” refer to Disc Medicine, Inc. The mailing address of our principal executive offices is Disc Medicine, Inc., 321 Arsenal Street, Suite 101, Watertown, Massachusetts 02472.

All properly submitted proxies will be voted in accordance with the instructions contained in those proxies. If no instructions are specified, the proxies will be voted in accordance with the recommendation of our board of directors with respect to each of the matters set forth in this proxy statement and the accompanying proxy card. You may revoke your proxy at any time before it is exercised at the meeting by giving our corporate secretary written notice to that effect.

We plan to mail a Notice of Internet Availability of Proxy Materials, or the Notice, to our stockholders on or about April 24, 2023, and it contains instructions on how to access our proxy materials, including this proxy statement and our 2022 Annual Report, over the Internet.

We are utilizing a virtual-only meeting format in order to leverage technology to enhance stockholder access to the Annual Meeting by enabling attendance and participation from any location around the world. We believe that the virtual-only meeting format will give stockholders the opportunity to participate fully and equally, and without cost, and to exercise the same rights as if they had attended an in-person meeting. We believe that these measures will enhance stockholder access and encourage participation and communication with our board of directors and management. In addition, the virtual-only meeting format increases our ability to engage with all stockholders, regardless of size, resources or physical location.

We are an “emerging growth company” under applicable federal securities laws and therefore permitted to conform with certain reduced public company reporting requirements. As an emerging growth company, we provide in this proxy statement the scaled disclosure permitted under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, including the compensation disclosures required of a “smaller reporting company,” as that term is defined in Rule 12b-2 promulgated under the Securities Exchange Act of 1934, as amended, or the Exchange Act. In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory basis, of the compensation of our named executive officers or the frequency with which such votes must be conducted. We will remain an “emerging growth company” until the earliest of (i) the last day of the fiscal year following the fifth anniversary of our initial public offering; (ii) the last day of the fiscal year in which our total annual gross revenue is

5

equal to or more than $1.235 billion; (iii) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the Securities and Exchange Commission, or the SEC. Even after we are no longer an “emerging growth company,” we may remain a “smaller reporting company.”

the Annual Meeting of Stockholders to be Held on June 9, 2023:

DISC MEDICINE, INC.

PROXY STATEMENT

FOR THE 2023 ANNUAL MEETING OF STOCKHOLDERS

GENERA L INFORMATION

When are this proxy statement and the accompanying materials scheduled to be sent to stockholders?

We are mailing to our stockholders the Notice instead of a paper copy of this proxy statement and our 2022 Annual Report, on or about April 24, 2023, and it contains instructions on how to access those documents over the Internet. You will need the control number included on the Notice, proxy card or voting instruction form to access these materials. If you would like to receive a print version of the proxy materials, free of charge, please follow the instructions on the Notice.

Who is soliciting my vote?

Our board of directors is soliciting your vote for the Annual Meeting.

When is the record date for the Annual Meeting?

The record date for determination of stockholders entitled to vote at the Annual Meeting is the close of business on April 14, 2023.

How many votes can be cast by all stockholders?

There were 19,793,870 shares of our common stock, par value $0.0001 per share, outstanding on April 14, 2023, all of which are entitled to vote with respect to all matters to be acted upon at the Annual Meeting. Each stockholder of record is entitled to one vote for each share of our common stock held by such stockholder. As the stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or vote on your own behalf at our Annual Meeting. None of our shares of preferred stock were outstanding as of April 14, 2023.

Who is entitled to vote?

Registered Stockholders. If shares of our common stock are registered directly in your name with our transfer agent, you are considered the stockholder of record with respect to those shares. As the stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or vote on your own behalf at our Annual Meeting. Throughout this proxy statement, we refer to these registered stockholders as “stockholders of record.”

Street Name Stockholders. If shares of our common stock are held on your behalf in a brokerage account or by a bank or other nominee, you are considered to be the beneficial owner of shares that are held in “street name,” and the proxy materials were forwarded to you by your broker or nominee, who is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, bank or other nominee as to how to vote your shares. Beneficial owners are also invited to attend our Annual Meeting. However, since a beneficial owner is not the stockholder of record, you may not vote your shares of our common stock on your own behalf at the Annual Meeting unless you follow your broker’s procedures for obtaining a legal proxy. Note you should also be receiving a voting instruction form for you to use from your broker. Throughout this proxy statement, we refer to stockholders who hold their shares through a broker, bank or other nominee as “street name stockholders.”

How do I vote?

If you are a stockholder of record, there are four ways to vote:

•
By Internet. You may vote at www.proxyvote.com, using the voter control number printed on the furnished proxy card, 24 hours a day, seven days a week. Use the Internet to transmit your voting instructions and for electronic delivery of information up until 11:59 p.m. Eastern Time the day before the meeting date. You will need the control number included on your proxy card.

7

•
By Telephone. You may vote using a touch-tone telephone by calling 1-800-690-6903, 24 hours a day, seven days a week. Use any touch-tone telephone to transmit your voting instructions up until 11:59 p.m. Eastern Time the day before the meeting date. You will need the control number included on your proxy card.
•
By Mail. If you requested and received a printed copy of the proxy materials, you may vote by completing, signing and mailing your proxy card in the postage-paid envelope we have provided or return it to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717. Votes submitted through the mail must be received by June 8, 2023.
•
By Internet at the Annual Meeting. Instructions on how to attend and vote at the Annual Meeting are described at www.virtualshareholdermeeting.com/IRON2023.

Even if you plan to attend our Annual Meeting, we recommend that you also vote by proxy so that your vote will be counted if you later decide not to attend the Annual Meeting.

If you are a street name stockholder, you will receive voting instructions from your broker, bank or other nominee. You must follow the voting instructions provided by your broker, bank or other nominee in order to instruct your broker, bank or other nominee on how to vote your shares. Street name stockholders should generally be able to vote by returning an instruction card, or by telephone or on the Internet. However, the availability of telephone and Internet voting will depend on the voting process of your broker, bank or other nominee. As discussed above, if you are a street name stockholder, you may not vote your shares on your own behalf at the Annual Meeting unless you obtain a legal proxy from your broker, bank or other nominee.

By Proxy

If you will not be attending the Annual Meeting, you may vote by proxy. You can vote by proxy over the Internet by following the instructions provided in the enclosed proxy card. Proxies submitted by mail must be received before the start of the Annual Meeting.

If you complete and submit your proxy before the Annual Meeting, the persons named as proxies will vote the shares represented by your proxy in accordance with your instructions. If you submit a proxy without giving voting instructions, your shares will be voted in the manner recommended by the board of directors on all matters presented in this proxy statement, and as the persons named as proxies may determine in their discretion with respect to any other matters properly presented at the Annual Meeting. You may also authorize another person or persons to act for you as proxy in a writing, signed by you or your authorized representative, specifying the details of those proxies’ authority. The original writing must be given to each of the named proxies, although it may be sent to them by electronic transmission if, from that transmission, it can be determined that the transmission was authorized by you.

If any other matters are properly presented for consideration at the Annual Meeting, including, among other things, consideration of a motion to adjourn the Annual Meeting to another time or place (including, without limitation, for the purpose of soliciting additional proxies), the persons named in your proxy and acting thereunder will have discretion to vote on those matters in accordance with their best judgment. We do not currently anticipate that any other matters will be raised at the Annual Meeting.

How do I attend the Annual Meeting online?

We will be hosting our Annual Meeting via live webcast only. All stockholders as of the record date, or their duly appointed proxies, can attend the Annual Meeting live online at www.virtualshareholdermeeting.com/IRON2023. The webcast will start at 9:00 a.m. Eastern Time on June 9, 2023. Stockholders may vote and ask questions while attending the Annual Meeting online. In order to be able to attend the Annual Meeting, you will need the 16-digit control number, which is located on your Notice of Internet Availability, on your proxy card or in the instructions accompanying your proxy materials. Instructions on how to participate in the Annual Meeting are also posted online at www.proxyvote.com.

8

How do I revoke my proxy?

You may revoke your proxy by (1) entering a new vote by mail that we receive before the start of the Annual Meeting or over the Internet or via telephone, (2) attending and voting at the Annual Meeting virtually (although attendance at the Annual Meeting will not in and of itself revoke a proxy), or (3) by filing an instrument in writing revoking the proxy or another duly executed proxy bearing a later date with our Corporate Secretary. Any written notice of revocation or subsequent proxy card must be received by our Corporate Secretary prior to the taking of the vote at the Annual Meeting. Such written notice of revocation or subsequent proxy card should be sent to our principal executive offices at Disc Medicine, Inc., 321 Arsenal Street, Suite 101, Watertown, Massachusetts 02472, Attention: Corporate Secretary.

If a broker, bank, or other nominee holds your shares, you must contact such broker, bank, or nominee in order to find out how to change your vote.

How is a quorum reached?

Our Amended and Restated Bylaws, or bylaws, provide that a majority of the outstanding shares entitled to vote, present in person or represented by proxy, will constitute a quorum for the transaction of business at the Annual Meeting.

Under the Delaware General Corporation Law, shares that are voted “abstain” or “withheld” and broker “non-votes” are counted as present for purposes of determining whether a quorum is present at the Annual Meeting. If a quorum is not present, the meeting may be adjourned until a quorum is obtained.

How is the vote counted?

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 Amended and Restated Certificate of Incorporation, or certificate of incorporation, or bylaws. Abstentions, votes withheld 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.

If your shares are held in “street name” by a brokerage firm, your brokerage firm is required to vote your shares according to your instructions. If you do not give instructions to your brokerage firm, the brokerage firm will still be able to vote your shares with respect to certain “discretionary” items, but will not be allowed to vote your shares with respect to “non-discretionary” items. Proposal No. 1 is a “non-discretionary” item. If you do not instruct your broker how to vote your shares with respect to this proposal, your broker may not vote for this proposal, and those shares will be counted as broker “non-votes.” Proposal No. 2 is considered to be a discretionary item, and your brokerage firm will be able to vote your shares on this proposal even if it does not receive instructions from you.

Who pays the cost for soliciting proxies?

We are making this solicitation and will pay the entire cost of preparing and distributing our proxy materials and soliciting votes. If you choose to access the proxy materials or vote over the Internet, you are responsible for any Internet access charges that you may incur. Our officers and employees may, without compensation other than their regular compensation, solicit proxies through further mailings, personal conversations, facsimile transmissions, e-mails, or otherwise. Proxy solicitation expenses that we will pay include those for preparation, mailing, returning, and tabulating the proxies.

How may stockholders submit matters for consideration at an Annual Meeting?

The required notice must be in writing and received by our corporate secretary at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary of the preceding year’s annual meeting. However, in the event that the date of the annual meeting is advanced by more than 30 days, or delayed by more than

9

60 days, from the first anniversary of the preceding year’s annual meeting, or if no annual meeting were held in the preceding year, a stockholder’s notice must be so received no earlier than the 120th day prior to such annual meeting and not later than the close of business on the later of (A) the 90th day prior to such annual meeting and (B) the tenth day following the day on which notice of the date of such annual meeting was mailed or public disclosure of the date of such annual meeting was made, whichever last occurs.

In addition, any stockholder proposal intended to be included in the proxy statement for the next annual meeting of our stockholders in 2024 must also satisfy the requirements of SEC Rule 14a-8 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and be received not later than December 26, 2023. If the date of the annual meeting is moved by more than 30 days from the date contemplated at the time of the previous year’s proxy statement, then notice must be received within a reasonable time before we begin to print and send proxy materials. If that happens, we will publicly announce the deadline for submitting a proposal in a press release or in a document filed with the SEC.

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

We plan to announce preliminary voting results at the Annual Meeting. Final voting results will be published in a Current Report on Form 8-K, or Form 8-K, that we expect to file with the SEC 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.

PROP OSAL NO. 1 – ELECTION OF CLASS II and class iii DIRECTORs

Our board of directors currently consists of nine members. Jay Backstrom, M.D., M.P.H. has informed our board of directors that he will be resigning from the board of directors effective as of the close of business on June 9, 2023. Dr. Backstrom’s decision to resign is not the result of any disagreement with the Company relating to any of our operations, policies or practices. Following the resignation of Dr. Backstrom, we will have eight directors. In accordance with the terms of our certificate of incorporation and bylaws, our board of directors is divided into three classes, Class I, Class II and Class III, with members of each class serving staggered three-year terms. However, because we did not hold an annual meeting of stockholders in 2022, due to the anticipation and timing of our merger with Gemini Therapeutics, Inc., or Gemini, which we completed in December 2022, or the merger, our certificate of incorporation requires that the election of both Class II and Class III directors be voted on at the Annual Meeting. The members of the classes are divided as follows:

•
the Class I directors are Mona Ashiya, Ph.D., Kevin Bitterman, Ph.D. and Jay Backstrom, M.D., M.P.H., and their terms will expire at the annual meeting of stockholders to be held in 2024. Dr. Backstrom will be resigning from our board of directors effective as of the close of business on June 9, 2023;
•
the Class II directors are Georges Gemayel, Ph.D., Mark Chin, MS, MBA and Liam Ratcliffe, M.D., Ph.D., and their terms will expire at the Annual Meeting; and
•
the Class III directors are Donald Nicholson, Ph.D., William White, MPP, J.D. and John Quisel, J.D., Ph.D., and their terms will expire at the Annual Meeting.

Upon the expiration of the term of a class of directors, directors in that class will typically be eligible to be elected for a new three-year term at the annual meeting of stockholders in the year in which their term expires. However, because we, operating as Gemini, did not hold an annual meeting of stockholders in 2022, our Class II directors will be elected for a two-year term expiring at our annual meeting of stockholders to be held in 2025.

Our certificate of incorporation and bylaws provide that the authorized number of directors may be changed only by resolution of our board of directors. Our certificate of incorporation also provides that our directors may be removed only for cause by the affirmative vote of the holders of at least two thirds (2/3) or more of the outstanding shares then entitled to vote in an annual election of directors, and that any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office.

Our board of directors has nominated (i) each of Georges Gemayel, Ph.D., Mark Chin, MS, MBA and Liam Ratcliffe, M.D., Ph.D. for election as a Class II director at the Annual Meeting to serve until the annual meeting of stockholders to be held in 2025 and until their successor has been duly elected and qualified, or until their earlier death, resignation or removal and (ii) each of Donald Nicholson, Ph.D., William White, MPP, J.D. and John Quisel, J.D., Ph.D. for election as a Class III director at the Annual Meeting to serve until the annual meeting of stockholders to be held in 2026 and until their successor has been duly elected and qualified, or until their earlier death, resignation or removal. The nominees are presently directors, and have indicated a willingness to continue to serve as directors, if elected. If the nominees become unable or unwilling to serve, however, the properly submitted proxies may be voted for substitute nominees selected by our board of directors.

Our Nominating and Corporate Governance Committee Policies and Procedures for Director Candidates, or the Director Guidelines, provide that the value of diversity should be considered in determining director candidates as well as other factors such as a candidate’s character, integrity, judgment, skills, education, expertise, business acumen and experience and absence of conflicts of interest. However, we do not have a formal policy concerning the diversity of the board of directors. Our priority in selection of board members is identification of members who will further the interests of our stockholders through their established records of professional accomplishment, their ability to contribute positively to the collaborative culture among board members, and their knowledge of our business and understanding of the competitive landscape in which we operate and adherence to high ethical standards. Although the nominating and corporate governance committee does not have a formal diversity policy and does not follow any ratio or formula with respect to diversity in order to determine the appropriate composition of the board of directors, the nominating and corporate governance committee and the full board of directors are committed to creating a board

11

of directors with diversity of expertise and experience in substantive matters pertaining to our business relative and diversity of background and perspective, including, but not limited to, with respect to gender, ethnicity, religion, nationality, disability and sexual orientation. Our board of directors and nominating and corporate governance committee are committed to identifying, recruiting and advancing candidates offering such diversity in future searches.

PROPOS AL NO. 2 – RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS DISC MEDICINE, INC.’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2023

Our stockholders are being asked to ratify the appointment by the audit committee of the board of directors of Ernst & Young LLP, or EY, as our independent registered public accounting firm for the fiscal year ending December 31, 2023. EY has served as our independent registered public accounting firm since 2020.

The audit committee is solely responsible for selecting our independent registered public accounting firm for the fiscal year ending December 31, 2023. Stockholder approval is not required to appoint EY as our independent registered public accounting firm. However, the board of directors believes that submitting the appointment of EY to the stockholders for ratification is good corporate governance. If the stockholders do not ratify this appointment, the audit committee will reconsider whether to retain EY. If the selection of EY is ratified, the audit committee, at its discretion, may direct the appointment of a different independent registered public accounting firm at any time it decides that such a change would be in the best interest of Disc and its stockholders.

A representative of EY is expected to be present at the Annual Meeting and will have an opportunity to make a statement if he or she desires to do so and to respond to appropriate questions from our stockholders.

We incurred the following fees from EY for the audit of the financial statements and for other services provided during the years ended December 31, 2022 and 2021.

|  | 2022 |  |  | 2021 |
Audit fees(1) |  | $ | 1,145,000 |  |  | $ | 1,085,000 |
Audit-Related fees(2) |  |  | — |  |  |  | — |
Tax fees(3) |  |  | 35,000 |  |  |  | — |
All other fees(4) |  |  | — |  |  |  | — |
Total fees |  | $ | 1,180,000 |  |  | $ | 1,085,000 |

(1)
Audit Fees consist of fees billed for professional services rendered in connection with the audit of our annual financial statements and reviews of our quarterly financial statements for those fiscal years. This category also includes fees for services incurred in connection with the filing of our Registration Statement on Form S-4 and related services that are normally provided in connection with regulatory filings. We engaged EY in 2022 to audit our 2022 and 2021 annual financial statements.
(2)
Audit-related fees consist of services that are reasonably related to the performance of the audit or review of our financial statements. There were no such fees incurred in 2022 or 2021.
(3)
Tax Fees consist of fees for tax compliance, tax advice and tax planning.
(4)
There were no other fees incurred in 2022 or 2021.

Audit Committee Pre-approval Policy and Procedures

It is the policy of our Audit Committee that all services to be provided by our independent registered public accounting firm, including audit services and permitted audit-related and non-audit services, must be approved in advance by our Audit Committee, except that pre-approval is not required for the provision of non-audit services if the “de minimis” provisions of Section 10A(i)(1)(B) of the Exchange Act are satisfied. The Audit Committee may delegate authority to pre-approve non-audit services to one or more members of the Audit Committee, who shall present all decisions made to pre-approve an activity to the full Audit Committee at its first meeting following such decision. All services provided by EY during fiscal years 2022 and 2021 were pre-approved by the Audit Committee in accordance with the pre-approval policy described above.

Vote Required; Board Recommendation

The affirmative vote of a majority of votes properly cast for and against this Proposal No. 2 is required to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023.

The board of directors recommends voting “FOR” Proposal No. 2 to ratify the appointment of Ernst & Young LLP as Disc Medicine, Inc.’s independent registered public accounting firm for the fiscal year ending December 31, 2023.

CORPORATE GOVERNANCE

Director Nomination Process

Our board of directors is responsible for selecting its own members. The board of directors delegates the selection and nomination process to our nominating and corporate governance committee, with the expectation that other members of the board of directors, and of management, will be requested to take part in the process as appropriate.

Generally, our nominating and corporate governance committee identifies candidates for director nominees in consultation with management, through the use of independent director search firms, through recommendations submitted by stockholders or through such other methods as the nominating and corporate governance committee deems to be helpful to identify candidates. Once candidates have been identified, the nominating and corporate governance committee confirms that the candidates meet the minimum qualifications for director nominees established by the nominating and corporate governance committee. These criteria include, among other things, the skills of the candidate, his or her depth and breadth of business experience and other background characteristics, his or her independence and the needs of the board of directors.

The nominating and corporate governance committee may gather information about the candidates through meetings from time to time, questionnaires or background checks to evaluate biographical information and background material relating to potential candidates, and interviews of selected candidates by members of the committee and our board of directors. The nominating and corporate governance committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of our board of directors. Based on the results of the evaluation process, the nominating and corporate governance committee recommends candidates for the board of directors’ approval as director nominees for election to the board of directors.

The board of directors does not believe that limits on the number of consecutive terms a director may serve or on the directors’ ages are appropriate at this stage. Instead, each director’s performance and their continued service is assessed by the nominating and corporate governance committee in light of the needs of the board of directors and other relevant factors.

Stockholders may recommend individuals to the nominating and corporate governance committee for consideration as potential director candidates. Any such proposals should be submitted to our corporate secretary at our principal executive offices no later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the one-year anniversary of the date of the preceding year’s annual meeting and should include appropriate biographical and background material to allow the nominating and corporate governance committee to properly evaluate the potential director candidate and the number of shares of our stock beneficially owned by the stockholder proposing the candidate. Stockholder proposals should be addressed to Disc Medicine, Inc., 321 Arsenal Street, Suite 101, Watertown, MA 02472, Attention: Corporate Secretary. Assuming that biographical and background material has been provided on a timely basis in accordance with our bylaws, any recommendations received from stockholders will be evaluated in the same manner as potential nominees proposed by the nominating and corporate governance committee. If our board of directors determines to nominate a stockholder-recommended candidate and recommends his or her election, then his or her name will be included on our proxy card for the next annual meeting of stockholders. See the section of this proxy statement titled “Stockholder Proposals” for a discussion of submitting stockholder proposals.

Director Independence

Our common stock is listed on The Nasdaq Global Market, or Nasdaq. Under the Nasdaq listing rules, independent directors must comprise a majority of a listed company’s board of directors within twelve months from the date of listing. In addition, the Nasdaq listing rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent within twelve months from the date of listing. Audit committee members must also satisfy additional independence criteria, including those set forth in Rule 10A 3 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and compensation committee members must also satisfy the independence criteria set forth in Rule 10C 1 under the Exchange Act. Under Nasdaq listing rules, a director will only qualify as an “independent director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

In order to be considered independent for purposes of Rule 10A 3 under the Exchange Act, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board of directors committee: (1) accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries, other than compensation for board of directors service; or (2) be an affiliated person of the listed company or any of its subsidiaries. In order to be considered independent for purposes of Rule 10C 1, the board of directors must consider, for each member of a compensation committee of a listed company, all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: the source of compensation of the director, including any consulting advisory or other compensatory fee paid by such company to the director, and whether the director is affiliated with the company or any of its subsidiaries or affiliates.

Our board of directors has determined that each of our directors, with the exception of Dr. Quisel, who serves as our President and Chief Executive Officer, and Georges Gemayel, who served as the chief executive officer of Gemini prior to the merger, is an “independent director” within the meaning of the director independence standards established by the SEC and Nasdaq. Our board of directors also determined that Mark Chin, Liam Ratcliffe and William White who comprise our audit committee, Mona Ashiya, Kevin Bitterman and Donald Nicholson, who comprise our compensation committee, and Mona Ashiya, Kevin Bitterman, Donald Nicholson and Liam Ratcliffe, who comprise our nominating and corporate governance committee, satisfy the independence standards for such committees established by the SEC and Nasdaq, as applicable. In making such determinations, our board of directors evaluated, and will evaluate at least on an annual basis, all relationships that each such non-employee director has with our company in light of all facts and circumstances our board of directors deemed relevant in determining independence, including the beneficial ownership of our capital stock by each non-employee director.

The non-management directors meet at regularly scheduled executive sessions without management participation, and at least once each year an executive session with only independent directors present is held. In 2022, there were four executive sessions at which only the independent directors were present.

19

Board Diversity

Our nominating and corporate governance committee has a written board diversity policy and believes that our board of directors, taken as a whole, should embody a diverse set of skills, experience, knowledge and backgrounds, including an appropriate number of women directors. The board of directors has not adopted targets for the number or proportion of female directors as the company is committed to a merit-based system for board composition, which reflects a diverse and inclusive culture where directors believe that their views are heard, their concerns are attended to and they serve in an environment where bias, discrimination and harassment on any matter are not tolerated. When identifying suitable candidates for appointment to the board of directors, the company considers candidates on merit against objective criteria and the needs of the board of directors and considers the need to increase the number of women directors on the board of directors to meet the company’s goal. When recruiting new candidates for appointment, search protocols will go beyond the networks of existing board of director members and will incorporate diversity, including identification of female candidates, as a component. Any search firm engaged to assist the board of directors or the nominating and corporate governance committee in identifying candidates for appointment to the board of directors shall be directed to include women candidates and women candidates will be included in the board of director’s evergreen list of potential board of director nominees.

The company has not adopted targets for the number or proportion of directors who are members of a visible minority, Indigenous peoples or persons with a disability, or the designated groups, or for other diversity characteristics at this time. For now, the board of directors has chosen to focus on gender in exclusion to other diversity characteristics and the nominating and corporate governance committee does not specifically consider the level of representation of members of designated groups on the board of directors in identifying and nominating candidates for election or re-election to the board of directors.

The below board diversity matrix reports self-identified diversity statistics for the board of directors.

Board Committees

Our board of directors has established an audit committee, a compensation committee and a nominating and corporate governance committee. Each of these committees operates under a charter that has been approved by our board of directors. We believe that the composition and functioning of all of our committees comply with the applicable requirements of Nasdaq, the Sarbanes-Oxley Act of 2002 and SEC rules and regulations that are applicable to us. We intend to comply with future requirements to the extent they become applicable to us. A copy of each charter can be found under the “Investors & Media—Corporate Governance” section of our website, which is located at www.discmedicine.com. We do not incorporate the information contained on, or accessible through, our corporate website into this proxy statement, and you should not consider it a part of this proxy statement.

20

The board of directors has not adopted position descriptions for the chairperson of each committee. However, each committee chairperson understands that the responsibilities of the committee chairperson include responsibility for providing leadership to the committee, including chairing meetings in a manner that facilitates open discussions and expressions of competing views, and reporting to the board of directors on the work of the committee and any recommendations for approval by the board of directors. The committee chairperson also ensures that the committee receives the information required for the performance of its responsibilities. The board of directors may also establish other committees from time to time to assist the company and the board of directors.

Audit Committee

The primary purpose of our audit committee is to discharge the responsibilities of the board of directors with respect to our accounting, financial, and other reporting and internal control practices and to oversee our independent registered accounting firm. The report of the audit committee is included in this proxy statement under “Report of the Audit Committee.”

Specific responsibilities of our audit committee include:

•
selecting a qualified firm to serve as the independent registered public accounting firm to audit our financial statements
•
helping to ensure the independence and performance of the independent registered public accounting firm;
•
discussing the scope and results of the audit with the independent registered public accounting firm, and reviewing, with management and the independent accountants, our interim and year-end operating results;
•
developing procedures for employees to submit concerns anonymously about questionable accounting or audit matters;
•
reviewing policies on risk assessment and risk management;
•
reviewing related party transactions;
•
obtaining and reviewing a report by the independent registered public accounting firm at least annually, that describes its internal quality-control procedures, any material issues with such procedures, and any steps taken to deal with such issues when required by applicable law; and
•
approving (or, as permitted, pre-approving) all audit and all permissible non-audit service to be performed by the independent registered public accounting firm.

The members of the Audit Committee are William White, Liam Ratcliffe and Mark Chin. William White is the chair of the Audit Committee and our board of directors has determined that he qualifies as an “audit committee financial expert” within the meaning of SEC regulations. To qualify as independent to serve on our audit committee, listing standards of Nasdaq and the applicable SEC rules require that a director not accept any consulting, advisory or other compensatory fee from us, other than for service as a director, or be an affiliated person of the company. During the fiscal year ended December 31, 2022, the Disc audit committee met four times. We believe that the composition of the audit committee complies with the applicable requirements of the rules and regulations of Nasdaq and the SEC.

Compensation Committee

The primary purpose of our compensation committee is to discharge the responsibilities of the board of directors to oversee our compensation policies, plans and programs and to review and determine the compensation to be paid to our executive officers, directors and other senior management, as appropriate.

Specific responsibilities of our compensation committee include:

•
reviewing and approving, or recommending that the board of directors approve, the compensation of our executive officers;

21

•
reviewing and recommending to our board of directors the compensation of our directors;
•
administering our stock and equity incentive plans;
•
selecting independent compensation consultants and assessing whether there are any conflicts of interest with any of the committee’s compensation advisors;
•
reviewing and approving, or recommending that the board of directors approve, incentive compensation and equity plans, severance agreements, change-of-control protections and any other compensatory arrangements for our executive officers and other senior management, as appropriate;
•
reviewing and establishing general policies relating to compensation and benefits of our employees; and
•
reviewing our overall compensation philosophy.

The members of the Compensation Committee are Donald Nicholson, Mona Ashiya and Kevin Bitterman. Dr. Nicholson is the chair of the Compensation Committee. Each member of our compensation committee will be a “non-employee” director within the meaning of Rule 16b-3 of the rules promulgated under the Exchange Act and independent within the meaning of the independent director guidelines of Nasdaq. During the fiscal year ended December 31, 2022, the Disc compensation committee met three times. We believe that the composition of the compensation committee complies with the applicable requirements of the rules and regulations of Nasdaq and the SEC.

Our Compensation Committee makes most of the significant adjustments to annual compensation, determines bonus and equity awards and establishes new performance objectives. However, our 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 the Company’s compensation strategy, potential modifications to that strategy and new trends, plans or approaches to compensation. Generally, the Compensation Committee’s process comprises two related elements: the determination of compensation levels and the establishment of performance objectives for the current year. For executives other than the Chief Executive Officer, our 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, company stock performance data, analyses of historical executive compensation levels and current company-wide compensation levels and analyses of executive and director compensation paid at a peer group of other companies approved by our Compensation Committee. In 2022, the Compensation Committee retained the services of Pearl Meyer & Partners, LLC, or Pearl Meyer, as its external, independent compensation consultant and considered Pearl Meyer’s input on certain compensation matters as they deemed appropriate.

Compensation Consultants

In fiscal year 2022, our compensation committee engaged Pearl Meyer to provide compensation consulting services. During fiscal year 2022, Pearl Meyer’s services included advising on equity compensation programs and the development of the Company’s peer group and providing support and analysis regarding executive and director compensation. Our compensation committee has assessed the independence of Pearl Meyer consistent with SEC rules and Nasdaq listing standards and has concluded that the engagement of Pearl Meyer does not raise any conflict of interest.

Nominating and Corporate Governance Committee

Specific responsibilities of our nominating and corporate governance committee include:

•
identifying, evaluating and selecting, or recommending that the board of directors approve, nominees for election to the board of directors;

22

•
evaluating the performance of the board of directors and of individual directors;
•
reviewing developments in corporate governance practices;
•
evaluating the adequacy of our corporate governance practices and reporting;
•
reviewing management succession plans; and
•
developing and making recommendations to the board of directors regarding corporate governance guidelines and matters.

The members of the Nominating and Corporate Governance Committee are Kevin Bitterman, Mona Ashiya, Donald Nicholson and Liam Ratcliffe. Dr. Bitterman is the chair of the Nominating and Corporate Governance Committee. During the fiscal year ended December 31, 2022, the Disc nominating and corporate governance committee did not meet. We believe that the composition of the nominating and corporate governance committee meets the requirements for independence under, and the functioning of such nominating and corporate governance committee complies with, any applicable requirements of the rules and regulations of Nasdaq and the SEC.

The nominating and corporate governance committee considers candidates for board of directors membership suggested by its members and the chief executive officer. Additionally, in selecting nominees for directors, the nominating and corporate governance committee will review candidates recommended by stockholders in the same manner and using the same general criteria as candidates recruited by the committee and/or recommended by our board of directors. Any stockholder who wishes to recommend a candidate for consideration by the committee as a nominee for director should follow the procedures described later in this proxy statement under the heading “Stockholder Proposals.” The nominating and corporate governance committee will also consider whether to nominate any person proposed by a stockholder in accordance with the provisions of our bylaws relating to stockholder nominations as described later in this proxy statement under the heading “Stockholder Proposals.”

Identifying and Evaluating Director Nominees.

Our board of directors is responsible for filling vacancies on our board of directors and for nominating candidates for election by our stockholders each year in the class of directors whose term expires at the relevant annual meeting. The board of directors delegates the selection and nomination process to the nominating and corporate governance committee, with the expectation that other members of the board of directors, and of management, will be requested to take part in the process as appropriate.

Generally, the nominating and corporate governance committee identifies candidates for director nominees in consultation with management, through the recommendations submitted by stockholders or through such other methods as the nominating and corporate governance committee deems to be helpful to identify candidates. Once candidates have been identified, the nominating and corporate governance committee confirms that the candidates meet all of the minimum qualifications for director nominees established by the nominating and corporate governance committee. The nominating and corporate governance committee may gather information about the candidates through interviews, detailed questionnaires, comprehensive background checks or any other means that the nominating and corporate governance committee deems to be appropriate in the evaluation process. The nominating and corporate governance committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of our board of directors. Based on the results of the evaluation process, the nominating and corporate governance committee recommends candidates for the board of directors’ approval to fill a vacancy or as director nominees for election to the board of directors by our stockholders each year in the class of directors whose term expires at the relevant annual meeting.

Board and Committee Meetings Attendance

The Disc board of directors held 14 meetings during 2022. During 2022, each of the Disc directors then in office attended at least 75% of the aggregate of all meetings of the board of directors and all meetings of the committees of the board of directors on which such director then served. A director’s attendance rate is considered by the nominating and corporate governance committee when making recommendations for re-appointment of the director. Continuing directors and nominees for election as directors in a given year are required to attend the annual meeting of stockholders, barring significant commitments or special circumstances.

Director Attendance at Annual Meeting of Stockholders

Directors are responsible for attending the annual meeting of stockholders to the extent practicable. We did not hold an annual meeting of stockholders in 2022.

Policy on Trading, Pledging and Hedging of Company Stock

Certain transactions in our securities (such as purchases and sales of publicly traded put and call options, and short sales) create a heightened compliance risk or could create the appearance of misalignment between management and stockholders. In addition, securities held in a margin account or pledged as collateral may be sold without consent if the owner fails to meet a margin call or defaults on the loan, thus creating the risk that a sale may occur at a time when an officer or director is aware of material, non-public information or otherwise is not permitted to trade in Company securities. Our insider trading policy expressly prohibits derivative transactions of our stock by our executive officers, directors, employees, designated consultants and contractors. Our insider trading policy expressly prohibits purchases of any derivative securities that provide the economic equivalent of ownership.

Compensation Committee Interlocks and Insider Participation

Each member of the compensation committee is a “non-employee” director within the meaning of Rule 16b-3 of the rules promulgated under the Exchange Act and independent within the meaning of the independent director guidelines of Nasdaq. None of our executive officers serves as a member of the board of directors or compensation committee of any entity that has one or more executive officers who serves on our board of directors or compensation committee.

Code of Business Conduct and Ethics

We have also adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A copy of the code is posted on the “Investors & Media— Corporate Governance” section of our website, which is located at www.discmedicine.com. If we make any substantive amendments to, or grant any waivers from, the code of business conduct and ethics for any officer or director, we will disclose the nature of such amendment or waiver on our website or in a Current Report on Form 8-K to be filed with the SEC. Employees are required to annually certify compliance with the code.

Board Leadership Structure

Our board of directors is currently chaired by Donald Nicholson, an independent director. Currently, the role of chairman of the board of directors is separated from the role of chief executive officer. Separating these positions allows our chief executive officer to focus on our day-to-day business, while allowing the chairperson of the board of directors to lead the board of directors in its fundamental role of providing advice to and independent oversight of management. The board of directors has not adopted a position description for the chairperson. However, there is a shared understanding on the board of directors of the chairperson’s responsibilities. The chairperson’s primary role is to provide leadership to the board of directors and its committees, including chairing meetings in a manner that facilitates open discussions and expressions of competing views. The chairperson is also responsible for, among other things, assisting the board of directors in obtaining information required for the performance of their duties, retaining appropriately qualified and independent advisors as needed, working with the board to support board development and to ensure a proper committee structure is in place, providing a link between the board of directors and management and acting in an advisory capacity to the chief executive officer in all matters concerning the interests and management of the company. Our board of directors recognizes the time, effort and energy that the chief executive officer must

24

devote to his position in the current business environment, as well as the commitment required to serve as the chairperson of the board of directors, particularly as the board of directors’ oversight responsibilities continue to grow. Our board of directors also believes that this structure ensures a greater role for the non-management directors in the oversight of our company and active participation of the independent directors in setting agendas and establishing priorities and procedures for the work of our board of directors. Our board of directors believes its administration of its risk oversight function has not affected its leadership structure. Although our by-laws do not require our chairperson of the board and chief executive officer positions to be separate, our board of directors believes that having separate positions is the appropriate leadership structure for us at this time. The board of directors has not adopted a separate position description for our chief executive officer. The role and responsibilities of the chief executive officer is delineated by frequent discussion and interaction between the board chairperson and the chief executive officer.

Oversight of Risk

Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including risks relating to our financial condition, development and commercialization activities, operations, strategic direction and intellectual property as more fully discussed under “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. Management is responsible for the day-to-day management of risks we face, while our board of directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our board of directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

Our board of directors regularly discusses with management our major risk exposures, the potential impact of these risks on our business and the steps we take to manage them. The risk oversight process includes receiving regular reports from board of director committees and members of senior management to enable our board of directors to understand the company’s risk identification, risk management and risk mitigation strategies with respect to areas of potential material risk, including operations, finance, legal, regulatory, strategic and reputational risk.

The audit committee reviews information regarding liquidity and operations, and oversees our management of financial risks. Periodically, the audit committee reviews our policies with respect to risk assessment, risk management, loss prevention and regulatory compliance. Oversight by the audit committee includes direct communication with our external auditors, and discussions with management regarding significant risk exposures and the actions management has taken to limit, monitor or control such exposures. The compensation committee is responsible for assessing whether any of our compensation policies or programs has the potential to encourage excessive risk-taking. The nominating and corporate governance committee manages risks associated with the independence of the board of directors, corporate disclosure practices, and potential conflicts of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire board of directors is regularly informed through committee reports about such risks. Matters of significant strategic risk are considered by our board as a whole.

Communication with the Directors of Disc Medicine, Inc.

Any interested party with concerns about our company may report such concerns to the board of directors or the chairman of our board of directors or the chairman of our nominating and corporate governance committee, by submitting a written communication to the attention of such director at the following address:

c/o Disc Medicine, Inc.

321 Arsenal Street, Suite 101

Watertown, MA 02472

United States

You may submit your concern anonymously or confidentially by postal mail. You may also indicate whether you are a stockholder, customer, supplier, or other interested party.

25

A copy of any such written communication may also be forwarded to our legal counsel and a copy of such communication may be retained for a reasonable period of time. The director may discuss the matter with our legal counsel, with independent advisors, with non-management directors, or with our management, or may take other action or no action as the director determines in good faith, using reasonable judgment, and applying his or her own discretion.

Communications may be forwarded to other directors if they relate to important substantive matters and include suggestions or comments that may be important for other directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances, and matters as to which we tend to receive repetitive or duplicative communications.

The audit committee oversees the procedures for the receipt, retention, and treatment of complaints received by the company regarding accounting, internal accounting controls, or audit matters, and the confidential, anonymous submission by employees of concerns regarding questionable accounting, internal accounting controls or auditing matters. We have also established a toll-free telephone number for the reporting of such activity, which is (833) 869-0478.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors and officers and holders of more than 10% of our common stock to file with the SEC, initial reports of ownership of our common stock and other equity securities on a Form 3 and reports of changes in such ownership on a Form 4 or Form 5. Directors and officers and holders of 10% of our common stock are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file. The SEC has designated specific deadlines for these reports, and we must identify those persons who did not file these reports when due. To our knowledge, based solely on a review of copies of such forms furnished to us, and written representations made by our directors and officers regarding their filing obligations, we believe all Section 16(a) filing requirements were satisfied on a timely basis with respect to the year ended December 31, 2022.

NON-EMPLOYEE DIRECTOR COMPENSATION

The following table presents the total compensation for each person who served as a non-employee member of our board of directors during the fiscal year ended December 31, 2022.

Dr. Quisel is one of our named executive officers and, accordingly, the compensation that we pay to Dr. Quisel is discussed in the section of this proxy statement titled “—2022 Summary Compensation Table” and “—Narrative to Summary Compensation Table.”

Other than as described in this paragraph and set forth in the table and described more fully below, we did not pay any compensation or make any equity awards or non-equity awards to, or pay any other compensation to any of the non-employee members of our board of directors in 2022 for their services as members of the board of directors.

Narrative to Summary Compensation Table

Base Salaries

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 of directors taking into account each individual’s role, responsibilities, skills, and expertise. Base salaries are reviewed annually, typically in connection with our annual performance review process, approved by our board of directors, and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience. The annual base salaries for Dr. Quisel, Ms. Bryce and Mr. Yu were increased to $562,000, $419,000 and $419,000, respectively effective December 29, 2022 due to updated employment agreements entered into with the Company. Dr. Savage’s base salary was increased from $355,300 to $400,000 effective July 1, 2022 in connection with his mid-year performance review, and then increased again to $458,000 effective December 29, 2022 due to an updated employment agreement entered into with the Company.

Annual Bonuses

For the fiscal year ended December 31, 2022, each named executive officer was eligible to earn an annual cash bonus based on the achievement of certain corporate performance metrics. Corporate objectives were primarily based on development goals for our product candidates financing and business development goals. The target annual bonus for Drs. Quisel and Savage, Ms. Bryce and Mr. Yu for 2022 was 50%, 40%, 40% and 40% of their respective annual base salary as in effect on December 28, 2022 (i.e., prior to the increase provided in the updated employment agreements).

Equity Compensation

We believe that equity grants provide executives with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executives and stockholders. In addition, we believe that equity grants promote executive retention because they incentivize executive officers to remain employed during the vesting period. During the fiscal year ended December 31, 2022, we granted stock option awards to each of our named executive officers, as described in more detail in the “Outstanding Equity Awards at Fiscal 2022 Year-End” table.

Health and Welfare Benefits

Our named executive officers, like all full-time employees, are eligible to participate in our health and welfare benefit plans.

Perquisites and Personal Benefits

We generally do not provide perquisites to our executives.

401(k) Plan

We maintain a tax-qualified retirement plan that provides eligible U.S. employees with an opportunity to save for retirement on a tax-advantaged basis, or the 401(k) Plan. Participants in the 401(k) Plan are able to defer eligible compensation subject to applicable annual Internal Revenue Code limits. We did not provide a matching contribution to the named executive officers or to any employees in 2022. The 401(k) Plan is intended to be qualified under Section 401(a) of the Internal Revenue Code with the 401(k) Plan’s related trust intended to be tax exempt under Section 501(a) of the Internal Revenue Code. As a tax-qualified retirement plan, pre-tax contributions to the 401(k) Plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) Plan, and earnings on Roth contributions are not taxable when distributed from the 401(k) Plan.
