PROPOSAL 4: APPROVAL OF CONVERSION OF SERIES B PREFERRED STOCK ISSUED IN (A) DECEMBER 2023 AND (B) MARCH 2024
LEGAL MATTERS
Acquisition of Pre-Merger Spyre. On June 22, 2023 (the “Merger Closing”), we completed our acquisition (the “Merger”) of Spyre Therapeutics, Inc. (“Pre-Merger Spyre”) pursuant to an Agreement and Plan of Merger, dated as of June 22, 2023 (the “Acquisition Agreement”). Following the transactions contemplated by the Acquisition Agreement, Sequoia Merger Sub II, LLC, a Delaware limited liability company and our wholly owned subsidiary was the surviving entity and continued under the name “Spyre Therapeutics, LLC.” Pre-Merger Spyre was a pre-clinical stage biotechnology company that was incorporated on April 28, 2023 under the direction of Peter Harwin, a Managing Member of Fairmount Funds Management LLC (“Fairmount”), for the purpose of holding rights to certain intellectual property being developed by Paragon Therapeutics, Inc. (“Paragon”). Fairmount is a founder of Paragon. On November 28, 2023, we changed our name from “Aeglea BioTherapeutics, Inc.” to “Spyre Therapeutics, Inc.” and our Nasdaq ticker symbol from “AGLE” to “SYRE”.

These statements involve known and unknown risks, uncertainties and other factors that could cause our actual results to differ materially from the forward-looking statements expressed or implied in the Proxy Statement. Such risks, uncertainties and other factors include those risks described in “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s most recent Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (“SEC”) and other subsequent documents we file with the SEC.

PROXY STATEMENT
FOR THE 2024 ANNUAL MEETING OF STOCKHOLDERS
QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND VOTING
What Is the Purpose of These Proxy Materials?
We are making these proxy materials available to you in connection with the solicitation of proxies by the Board of Directors (the “Board”) of Spyre Therapeutics, Inc. (“we,” “us,” “our” or the “Company”) for use at the 2024 Annual Meeting of Stockholders (the “Annual Meeting”) to be held virtually on May 13, 2024 at 12:00 p.m. Eastern Time, or at any other time following adjournment or postponement thereof. You are invited to participate in the Annual Meeting and to vote on the proposals described in this proxy statement (the “Proxy Statement”). The proxy materials are being mailed to our stockholders on or about April 1, 2024.
Why Are We Holding a Virtual Annual Meeting?
We have adopted a virtual meeting format for the Annual Meeting to provide a consistent experience to all stockholders regardless of geographic location. We believe this expands stockholder access, improves communications and lowers our costs while reducing the environmental impact of the meeting. In structuring our virtual Annual Meeting, our goal is to enhance rather than constrain stockholder participation in the meeting, and we have designed the meeting to provide stockholders with the same rights and opportunities to participate as they would have at an in-person meeting.
Who Can Vote?
Only stockholders of record at the close of business on March 19, 2024 (the “Record Date”) are entitled to notice of the Annual Meeting and to vote on the proposals described in this Proxy Statement. At the close of business on the Record Date, 36,604,786 shares of our common stock were issued and outstanding. Shares of our preferred stock generally do not have voting rights and holders of our preferred stock are therefore not entitled to vote at the Annual Meeting.
What Is the Difference between Holding Shares as a Registered Stockholder and as a Beneficial Owner?
Registered Stockholder: Shares Registered in Your Name
If your shares of common stock are registered directly in your name with our transfer agent, Equiniti Trust Company, LLC (formerly known as American Stock Transfer & Trust Company LLC), you are considered to be, with respect to those shares of common stock, the registered stockholder, and these proxy materials are being sent directly to you by us.
Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary or Custodian
If your shares of common stock are held by a broker, fiduciary or custodian, you are considered the beneficial owner of shares of common stock held in “street name,” and these proxy materials are being forwarded to you from that broker, fiduciary or custodian.
How Can I Participate in the Virtual Annual Meeting?
Stockholders of record as of the close of business on the Record Date are entitled to participate in and vote at the Annual Meeting. To participate in the Annual Meeting, including to vote and ask questions, stockholders of record should go to the meeting website at www.virtualshareholdermeeting.com/SYRE2024, enter the 16-digit control number found on your proxy card, and follow the instructions on the website. If your shares are held in street name and your voting instruction form indicates that you may vote those shares through www.proxyvote.com, then you may access, participate in and vote at the Annual Meeting with the 16-digit access code indicated on that voting instruction form. Otherwise, stockholders who hold their shares in street name should contact their bank, broker or other nominee (preferably at least
3



five days before the Annual Meeting) and obtain a “legal proxy” in order to be able to attend, participate in or vote at the Annual Meeting.
We will endeavor to answer as many stockholder-submitted questions as time permits that comply with the Annual Meeting rules of conduct. We reserve the right to edit profanity or other inappropriate language and to exclude questions regarding topics that are not pertinent to meeting matters or Company business. If we receive substantially similar questions, we may group such questions together and provide a single response to avoid repetition.
The meeting webcast will begin promptly at 12:00 p.m. Eastern Time. Online check-in will begin approximately 15 minutes before then, and we encourage you to allow ample time for check-in procedures. If you experience technical difficulties during the check-in process or during the meeting, please call the number listed on the meeting website for technical support. Additional information regarding the rules and procedures for participating in the Annual Meeting will be set forth in our meeting rules of conduct, which stockholders can view during the meeting at the meeting website.
What Am I Voting on?
The proposals to be voted on at the Annual Meeting are as follows:
(1) Election of two Class II director nominees to serve until the 2027 Annual Meeting of Stockholders (“Proposal 1”);
(2) Approval, on a non-binding, advisory basis, of the compensation of the Company’s named executive officers (“Proposal 2”);
(3) Ratification of the appointment of PricewaterhouseCoopers LLP as the Company’s independent auditor for 2024 (“Proposal 3”);
(4) Approval of the issuance of shares of common stock upon conversion of the Series B Convertible Preferred Stock, par value $0.0001 per share (“Series B Preferred Stock”), issued in (a) December 2023 (“Proposal 4A”) and (b) March 2024 ("Proposal 4B" and, together with Proposal 4A, "Proposal 4");
(5) Approval of an amendment to the Company’s Amended and Restated Certificate of Incorporation (“Certificate of Incorporation”) to reflect Delaware law provisions regarding officer exculpation (“Proposal 5”); and
(6) Approval of an adjournment of the Annual Meeting, if necessary or appropriate, to solicit additional proxies (“Proposal 6”).
How Does the Board Recommend That I Vote?
The Board recommends that you vote your shares “FOR” each director nominee in Proposal 1 and “FOR” Proposals 2, 3, 4, 5 and 6.
What If Another Matter Is Properly Brought before the Annual Meeting?
As of the date of filing this Proxy Statement, 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 Annual Meeting, it is the intention of the persons named as proxies in the proxy card to vote on such matters in accordance with their best judgment.
How Many Votes Do I Have?
Each share of common stock is entitled to one vote on each proposal to be voted on at the Annual Meeting.
What Does It Mean If I Receive More Than One Set of Proxy Materials?
If you receive more than one set of proxy materials, your shares may be registered in more than one name or held in different accounts. Please cast your vote with respect to each set of proxy materials that you receive to ensure that all of your shares are voted.

How Do I Vote?
Even if you plan to attend the Annual Meeting, we recommend that you also submit your vote as early as possible in advance so that your vote will be counted if you later decide not to, or are unable to, virtually attend the Annual Meeting.
Registered Stockholder: Shares Registered in Your Name
If you are the registered stockholder, you may vote your shares online during the virtual Annual Meeting (see “How Can I Participate in the Virtual Annual Meeting?” above) or by proxy in advance of the Annual Meeting by Internet (at www.proxyvote.com), by completing and mailing a proxy card or by telephone (at (800) 690-6903).
Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary or Custodian
If you are the beneficial owner, you may vote your shares online during the virtual Annual Meeting (see “How Can I Participate in the Virtual Annual Meeting?” above) or you may direct your broker, fiduciary or custodian how to vote in advance of the Annual Meeting by following the instructions they provide.
What Happens If I Do Not Vote?
Registered Stockholder: Shares Registered in Your Name
If you are the registered stockholder and do not vote in one of the ways described above, your shares will not be voted at the Annual Meeting and will not be counted toward the quorum requirement.
Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary or Custodian
If you are the beneficial owner and do not direct your broker, fiduciary or custodian how to vote your shares, your broker, fiduciary or custodian will only be able to vote your shares with respect to proposals considered to be “routine.” Your broker, fiduciary or custodian is not entitled to vote your shares with respect to “non-routine” proposals, which we refer to as a “broker non-vote.” Whether a proposal is considered routine or non-routine is subject to stock exchange rules and final determination by the stock exchange. Even with respect to routine matters, some brokers are choosing not to exercise discretionary voting authority. As a result, we urge you to direct your broker, fiduciary or custodian how to vote your shares on all proposals to ensure that your vote is counted.
What If I Sign and Return a Proxy Card or Otherwise Vote but Do Not Indicate Specific Choices?
Registered Stockholder: Shares Registered in Your Name
The shares represented by each signed and returned proxy will be voted at the Annual Meeting by the persons named as proxies in the proxy card in accordance with the instructions indicated on the proxy card. However, if you are the registered stockholder and sign and return your proxy card without giving specific instructions, the persons named as proxies in the proxy card will vote your shares in accordance with the recommendations of the Board. Your shares will be counted toward the quorum requirement.
Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary or Custodian
If you are the beneficial owner and do not direct your broker, fiduciary or custodian how to vote your shares, your broker, fiduciary or custodian will only be able to vote your shares with respect to proposals considered to be “routine.” Your broker, fiduciary or custodian is not entitled to vote your shares with respect to “non-routine” proposals, resulting in a broker non-vote with respect to such proposals.
Can I Change My Vote after I Submit My Proxy?
Registered Stockholder: Shares Registered in Your Name
If you are the registered stockholder, you may revoke your proxy at any time before the final vote at the Annual Meeting in any one of the following ways:
(1) You may complete and submit a new proxy card, but it must bear a later date than the original proxy card;
5



(2) You may submit new proxy instructions via telephone or the Internet;
(3) You may send a timely written notice that you are revoking your proxy to our Corporate Secretary at the address set forth on the first page of this Proxy Statement; or
(4) You may vote by attending the Annual Meeting virtually. However, your virtual attendance at the Annual Meeting will not, by itself, revoke your proxy.
Your last submitted vote is the one that will be counted.
Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary or Custodian
If you are the beneficial owner, you must follow the instructions you receive from your broker, fiduciary or custodian with respect to changing your vote.
What Is the Quorum Requirement?
The holders of a majority of the shares of common stock outstanding and entitled to vote at the Annual Meeting, either virtually or represented by proxy, must be present at the Annual Meeting to constitute a quorum. A quorum is required to transact business at the Annual Meeting.
Your shares will be counted toward the quorum only if you submit a valid proxy (or a valid proxy is submitted on your behalf by your broker, fiduciary or custodian) or if you attend the Annual Meeting virtually and vote. Abstentions and broker non-votes, if any, will be counted toward the quorum requirement. If there is no quorum, the chair of the Annual Meeting or the holders of a majority of shares of common stock present at the Annual Meeting, either virtually or represented by proxy, may adjourn the Annual Meeting to another time or date.
How Many Votes Are Required to Approve Each Proposal and How Are Votes Counted?
Votes will be counted by American Election Services, the Inspector of Elections appointed for the Annual Meeting.
Proposal 1: Election of Directors
A nominee will be elected as a director at the Annual Meeting if the nominee receives a plurality of the votes cast “FOR” his election. “Plurality” means that the individuals who receive the highest number of votes cast “FOR” are elected as directors. Broker non-votes, if any, and votes that are withheld will not be counted as votes cast on the matter and will have no effect on the outcome of the election. Stockholders do not have cumulative voting rights for the election of directors.
Proposal 2: Non-Binding Advisory Vote on Executive Compensation
The affirmative vote of the holders of at least a majority of shares of common stock present or represented at the Annual Meeting and entitled to vote on the matter is required to approve this proposal. Abstentions will have the same effect as a vote “AGAINST” the matter. Broker non-votes, if any, will have no effect on the outcome of the matter.
Proposal 3: Ratification of Independent Auditor Appointment
The affirmative vote of the holders of at least a majority of shares of common stock present or represented at the Annual Meeting and entitled to vote on the matter is required to approve this proposal. Abstentions will have the same effect as a vote “AGAINST” the matter. Broker non-votes, if any, will have no effect on the outcome of the matter.
Proposal 4: Approval of Conversion of the Series B Preferred Stock Issued in (a) December 2023 and (b) March 2024
The affirmative vote of the holders of at least a majority of shares of common stock present or represented at the Annual Meeting and entitled to vote on the matter is required to approve each of Proposal 4A and Proposal 4B. Abstentions will have the same effect as a vote “AGAINST” the matter. Broker non-votes, if any, will have no effect on the outcome of the matter.
6



Proposal 5: Approval of an Amendment to the Company’s Certificate of Incorporation to Reflect Delaware Law Provisions Regarding Officer Exculpation
The affirmative vote of the holders of at least a majority of shares of common stock outstanding and entitled to vote at the Annual Meeting is required to approve this proposal. Abstentions and broker non-votes, if any, will have the same effect as a vote “AGAINST” the matter.
Proposal 6: Approval of an Adjournment of the Annual Meeting, if Necessary or Appropriate, to Solicit Additional Proxies
The affirmative vote of the holders of at least a majority of shares of common stock present or represented at the Annual Meeting and entitled to vote on the matter is required to approve this proposal. Abstentions will have the same effect as a vote “AGAINST” the matter. Broker non-votes, if any, will have no effect on the outcome of the matter.
Who Is Paying for This Proxy Solicitation?
We will pay the costs associated with the solicitation of proxies, including the preparation, assembly, printing and mailing of the proxy materials. We may also reimburse brokers, fiduciaries or custodians for the cost of forwarding proxy materials to beneficial owners of shares of common stock held in “street name.”
Our employees, officers and directors may solicit proxies in person or via telephone or the Internet. We will not pay additional compensation for any of these services.
How Can I Find out the Voting Results?
We expect to announce preliminary voting results at the Annual Meeting. Final voting results will be published in a Current Report on Form 8-K to be filed with the SEC within four business days after the Annual Meeting.

PROPOSAL 1: ELECTION OF DIRECTORS
In accordance with our Certificate of Incorporation and Bylaws, the Board has fixed the number of directors constituting the Board at eight. At the Annual Meeting, the stockholders will vote to elect the two Class II director nominees named in this Proxy Statement to serve until the 2027 Annual Meeting of Stockholders or until their successors are duly elected and qualified or until their earlier resignation or removal. Our Board has nominated Jeffrey W. Albers and Tomas Kiselak for election to our Board. Mr. Albers was appointed to the Board in November 2023 and was initially identified for a position on our Board by a third-party search firm. Mr. Kiselak was appointed to the Board in June 2023 in accordance with the Acquisition Agreement. Russell J. Cox will not stand for reelection at the Annual Meeting. As a result, the size of our Board will be reduced from eight to seven directors effective as of immediately prior to the closing of the polls at the Annual Meeting.
Our director nominees have indicated that they are willing and able to serve as directors. However, if either of them becomes unable or, for good cause, unwilling to serve, proxies may be voted for the election of such other person as shall be designated by our Board, or the Board may decrease the size of the Board.
Information Regarding Director Nominees and Continuing Directors
Our Board is divided into three classes, with members of each class holding office for staggered three-year terms. There are currently three Class I directors, whose terms expire at the 2026 Annual Meeting of Stockholders; two Class II directors, who are up for election at this meeting for a term expiring at the 2027 Annual Meeting of Stockholders; and two Class III directors, whose terms expire at the 2025 Annual Meeting of Stockholders.
Biographical and other information regarding our director nominees and directors continuing in office, including the primary skills and experiences considered by our Nominating and Corporate Governance Committee (the “Nominating Committee”) in determining to recommend them as nominees, is set forth below.

PROPOSAL 2: NON-BINDING ADVISORY VOTE ON EXECUTIVE COMPENSATION
In accordance with the rules of the SEC and pursuant to the Dodd-Frank Act, we are providing stockholders with an opportunity to make a non-binding, advisory vote on the compensation of our named executive officers. This non-binding advisory vote is commonly referred to as a “say-on-pay” vote.
The say-on-pay vote is a non-binding vote on the compensation of our “named executive officers,” as described in this Proxy Statement in the “Executive Compensation” section, the tabular disclosure regarding such compensation and the accompanying narrative disclosure. The say-on-pay vote is not a vote on our general compensation policies or compensation of our Board. Stockholders are urged to read the “Executive Compensation” section of the Proxy Statement, which discusses how our executive compensation policies and procedures implement our compensation philosophy. Our Compensation Committee and Board believe that these policies and procedures are effective in implementing our compensation philosophy and in achieving our goals.
As an advisory vote, this proposal is not binding. However, our Board and Compensation Committee, which is responsible for designing and administering our executive compensation program, value the opinions expressed by stockholders in their vote on this proposal and will consider the outcome of the vote when making future compensation decisions for our named executive officers.
We are required to hold a say-on-pay vote at least once every three years, and we have determined to hold a say-on-pay vote every year. Unless the Board modifies its policy on the frequency of holding say-on-pay advisory votes, the next say-on-pay vote is expected to occur in 2025.
Board Recommendation
The Board recommends a vote “FOR” this proposal.

PROPOSAL 3: RATIFICATION OF INDEPENDENT AUDITOR APPOINTMENT
Our Audit Committee has appointed PricewaterhouseCoopers LLP (“PwC”) as the Company’s independent registered public accounting firm for the year ending December 31, 2024. In this Proposal 3, we are asking stockholders to vote to ratify this appointment. Representatives of PwC are expected to be present at the Annual Meeting. They will have the opportunity to make a statement, if they desire to do so, and are expected to be available to respond to appropriate questions from stockholders.
Stockholder ratification of the appointment of PwC as the Company’s independent auditor is not required by law or our Bylaws. However, we are seeking stockholder ratification as a matter of good corporate practice. If our stockholders fail to ratify the appointment, the committee will reconsider its appointment. Even if the appointment is ratified, the committee, in its discretion, may direct the appointment of a different independent auditor at any time during the year if it determines that such a change would be in the best interests of the Company and our stockholders.
PwC has served as our independent auditor since 2014. The following table summarizes the audit fees billed and expected to be billed by PwC for the indicated fiscal years and the fees billed by PwC for all other services rendered during the indicated fiscal years. All services associated with such fees were pre-approved by our Audit Committee in accordance with the “Pre-Approval Policies and Procedures” described below.

Pre-Approval Policies and Procedures
Our Audit Committee has adopted procedures requiring the pre-approval of all audit and non-audit services performed by our independent auditor in order to assure that these services do not impair the auditor’s independence. These procedures generally approve the performance of specific services subject to a cost limit for all such services. This general approval is reviewed, and if necessary modified, at least annually. Management must obtain the specific prior approval of the committee for each engagement of our auditor to perform other audit-related or non-audit services. The committee does not delegate its responsibility to pre-approve services performed by our auditor to any member of management. The committee has delegated authority to the committee chair to pre-approve audit and non-audit services to be provided to us by our auditor provided that the fees for such services do not exceed $100,000. Any pre-approval of services by the committee chair pursuant to this delegated authority must be reported to the committee at its next regularly scheduled meeting.

PROPOSAL 4: APPROVAL OF CONVERSION OF SERIES B PREFERRED STOCK ISSUED IN (A) DECEMBER 2023 AND (B) MARCH 2024
Overview
In December 2023 and March 2024, we entered into definitive agreements for private placements with existing and new investors for aggregate gross proceeds of approximately $360 million, pursuant to which we issued an aggregate of 271,625 shares of Series B Preferred Stock. The Series B Preferred Stock is intended to have rights that are generally equivalent to shares of our common stock, provided that the Series B Preferred Stock does not have the right to vote on most matters (including the election of directors).
The conversion of the shares of Series B Preferred Stock issued in December 2023 and March 2024 into shares of common stock is being submitted for approval through two separate proposals — Proposal 4A and Proposal 4B. Under our Certificate of Incorporation and applicable Delaware law, Proposals 4A and 4B must be approved by the affirmative vote of the holders of at least a majority of shares of common stock present or represented at the Annual Meeting and entitled to vote on the matter.
Subject to the approval of Proposals 4A and 4B and certain beneficial ownership limitations set by each holder, each share of Series B Preferred Stock will automatically convert into 40 shares of common stock. Proposals 4A and 4B would provide the necessary approval to permit such conversions. Assuming approval of Proposals 4A and 4B and subject to certain beneficial ownership limitations, 10,865,000 shares of common stock are issuable upon conversion of the above-described Series B Preferred Stock. Approval of each of Proposal 4A and Proposal 4B is not conditioned upon stockholder approval of the other proposal. If Proposal 4A is approved and Proposal 4B is not approved, then the shares of Series B Preferred Stock issued in December 2023 will be eligible for conversion, but the shares of Series B Preferred Stock issued in March 2024 will not be eligible for conversion until such conversion is approved by stockholders. If Proposal 4B is approved and Proposal 4A is not approved, then the shares of Series B Preferred Stock issued in March 2024 will be eligible for conversion, but the shares of Series B Preferred Stock issued in December 2023 will not be eligible for conversion until such conversion is approved by stockholders.
Description of Series B Preferred Stock
Conversion. Following stockholder approval of Proposals 4A and 4B, effective as of 5:00 p.m. Eastern time on the third business day after the date on which such stockholder approval is received, each share of Series B Preferred Stock will automatically convert into 40 shares of common stock, subject to certain beneficial ownership limitations, including that a holder of Series B Preferred Stock is prohibited from converting shares of Series B Preferred Stock into shares of common stock if, as a result of such conversion, such holder, together with its affiliates, would beneficially own more than a specified percentage (initially set by the holder to a number up to 19.9% and thereafter adjusted) of the total number of shares of common stock issued and outstanding immediately after giving effect to such conversion.
Voting Rights. Except as otherwise required by law (e.g., voting on a change to the authorized shares of Series B Preferred Stock or the rights of such shares as required by Delaware law) and the Certificate of Designation of Preferences, Rights and Limitations of the Series B Preferred Stock that we filed with the Secretary of State of the State of Delaware on December 8, 2023 (as amended on March 18, 2024, the “Certificate of Designation”), the Series B Preferred Stock does not have voting rights. However, as long as any shares of Series B Preferred Stock are outstanding, we will not, without the affirmative vote of the holders of a majority of the then outstanding shares of the Series B Preferred Stock, (a) alter or change adversely the powers, preferences or rights given to the Series B Preferred Stock, (b) alter or amend the Certificate of Designation, or (c) amend the Certificate of Incorporation or other charter documents in any manner that adversely affects any rights of the holders of Series B Preferred Stock.
Dividends. Holders of Series B Preferred Stock are entitled to receive dividends on shares of Series B Preferred Stock equal, on an as-if-converted-to-common-stock basis, and in the same form as dividends actually paid on shares of common stock.
Liquidation and Dissolution. The Series B Preferred Stock ranks on parity with common stock upon any liquidation, dissolution or winding-up of the Company.
14



Reasons for Stockholder Approval. Our common stock is listed on The Nasdaq Global Select Market, and, as such, we are subject to the applicable rules of the Nasdaq Stock Market LLC, including Nasdaq Listing Rule 5635(d), which requires stockholder approval prior to the issuance of 20% or more of the common stock or 20% or more of the voting power outstanding before the issuance at a price that is less than the Minimum Price (as defined in the Nasdaq Listing Rules). Thus, in order to permit the issuance of common stock upon conversion of the Series B Preferred Stock, we must first obtain stockholder approval of this issuance.
Beneficial Ownership Limitations. We are not seeking stockholder approval of a potential “change in control” under Nasdaq Listing Rule 5635(b), which generally prohibits Nasdaq-listed companies from issuing common stock to a stockholder in a transaction that would cause the holder to beneficially own more than 20% of the then-outstanding common stock (subject to certain exceptions). Assuming that Proposal 4A and Proposal 4B are approved, the Series B Preferred Stock will continue to have a beneficial ownership conversion limit that would prevent a stockholder from converting its shares if, as a result of such conversion, it would beneficially own a number of shares above its applicable conversion blocker (which cannot exceed 19.9% of the total number of shares of common stock issued and outstanding immediately after giving effect to such conversion).
Interests of Certain Parties. Certain existing stockholders participated in the private placement transaction. See “Certain Relationships and Related Party Transactions—Related Party Transactions—Private Placement Transactions” for more information.
Proposal 4A: Approval of Conversion of Series B Preferred Stock Issued in December 2023
On December 7, 2023, we entered into a definitive agreement for a private placement with existing and new investors for gross proceeds of approximately $180 million, pursuant to which the investors purchased an aggregate of 6,000,000 shares of common stock at a price of $15.00 per share and 150,000 shares of Series B Preferred Stock at a price of $600.00 per share. Assuming approval of this Proposal 4A and subject to certain beneficial ownership limitations, 6,000,000 shares of common stock are issuable upon conversion of the above-described Series B Preferred Stock.
The sale into the public market of the shares of underlying common stock could materially and adversely affect the market price of our common stock. See “Risk Factors—Risks Related to Our Common Stock—Pursuant to the terms of the December 2023 SPA, we are required to recommend that our stockholders approve the conversion of all outstanding shares of our Series B Preferred Stock into shares of our common stock. We cannot guarantee that our stockholders will approve this matter, and if they fail to do so, we may be required to settle such shares in cash and our operations may be materially harmed” in our Annual Report on Form 10-K for the year ended December 31, 2023.
Proposal 4B: Approval of Conversion of Series B Preferred Stock Issued in March 2024
On March 18, 2024, we entered into a definitive agreement for a private placement with existing and new investors for gross proceeds of approximately $180 million, pursuant to which the investors purchased an aggregate of 121,625 shares of Series B Preferred Stock at a price of $1,480.00 per share. Assuming approval of this Proposal 4B and subject to certain beneficial ownership limitations, 4,865,000 shares of common stock are issuable upon conversion of the above-described Series B Preferred Stock.
The sale into the public market of the shares of underlying common stock could materially and adversely affect the market price of our common stock. See “Risk Factors—Risks Related to Our Common Stock—Pursuant to the terms of the December 2023 SPA, we are required to recommend that our stockholders approve the conversion of all outstanding shares of our Series B Preferred Stock into shares of our common stock. We cannot guarantee that our stockholders will approve this matter, and if they fail to do so, we may be required to settle such shares in cash and our operations may be materially harmed” in our Annual Report on Form 10-K for the year ended December 31, 2023.
Board Recommendation
The Board recommends a vote “FOR” each of Proposal 4A and Proposal 4B.

PROPOSAL 5: APPROVAL OF AN AMENDMENT TO THE COMPANY’S CERTIFICATE OF INCORPORATION TO REFLECT DELAWARE LAW PROVISIONS REGARDING OFFICER EXCULPATION
The State of Delaware, which is where we are incorporated, enacted legislation that expands exculpation protection to officers, thereby enabling companies to eliminate the monetary liability of certain officers in certain circumstances, similar to but more limited than the protection already afforded to directors under our Certificate of Incorporation.
In line with the update to Delaware law, we are proposing, and are asking stockholders to approve, an amendment to the Certificate of Incorporation to extend the exculpation provisions to certain officers (the “Proposed Certificate Amendment”). Specifically, the Proposed Certificate Amendment, which our Board of Directors has approved and declared advisable, would amend the Article VII: Director Liability as follows (in bold and underlined):
“ARTICLE VII: DIRECTOR AND OFFICER LIABILITY
1. Limitation of Liability. To the fullest extent permitted by law, no director or officer of the Corporation shall be personally liable for monetary damages for breach of fiduciary duty as a director or officer. Without limiting the effect of the preceding sentence, if the Delaware General Corporation Law is hereafter amended to authorize the further elimination or limitation of the liability of a director or officer, then the liability of a director or officer of the Corporation shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended.
2. Change in Rights. Neither any amendment nor repeal of this Article VII, nor the adoption of any provision of this Certificate of Incorporation inconsistent with this Article VII, shall eliminate, reduce or otherwise adversely affect any limitation on the personal liability of a director or officer of the Corporation existing at the time of such amendment, repeal or adoption of such an inconsistent provision.”
Purpose and Effect of the Proposed Certificate Amendment
The Board believes that it is important to extend exculpation protection to officers, to the fullest extent permitted by Delaware law, in order to better position the Company to attract and retain qualified and experienced officers. In the absence of such protection, such individuals might be deterred from serving as officers due to exposure to personal liability and the risk of incurring substantial expense in defending lawsuits, regardless of merit. The nature of their role often requires officers to make decisions on crucial matters and frequently in response to time-sensitive opportunities and challenges, which can create substantial risk of lawsuits seeking to impose liability with the benefit of hindsight and regardless of merit. Aligning the protections available to our officers with those available to our directors would empower officers to exercise their business judgment in furtherance of stockholder interests without the potential for distraction posed by the risk of personal liability.
The Board also believes that the Proposed Certificate Amendment would strike the appropriate balance between furthering the Company’s goals of attracting and retaining quality officers with promoting stockholder accountability because, consistent with the update to Delaware law and subject to future Delaware law updates, the Proposed Certificate Amendment would exculpate officers only in connection with direct claims brought by stockholders, including class actions, but would not eliminate or limit liability with respect to any of the following:
breach of fiduciary duty claims brought by the Company itself;
derivative claims brought by stockholders in the name of the Company;
any claims involving breach of the duty of loyalty to the Company or its stockholders;
any claims involving acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law; or
any claims involving transactions from which the officer derived an improper personal benefit.
Under the Proposed Certificate Amendment, and based on current Delaware law, the only officer positions eligible for exculpation would be (i) anyone serving as our President, Chief Executive Officer, Chief Operating Officer, Chief
16



Financial Officer, Chief Legal Officer, Chief Accounting Officer, Controller and Treasurer, (ii) any other Named Executive Officers, and (iii) any other officer who has consented to service of process in Delaware by written agreement.
Taking into account the narrow class and type of claims for which officers would be exculpated under current Delaware law, and the benefits the Board believes would accrue to the Company and its stockholders—enhancing our ability to attract and retain talented officers and potentially reducing future litigation costs associated with frivolous lawsuits—the Board determined that the Proposed Certificate Amendment is in the best interests of the Company and its stockholders.
A complete copy of our current Certificate of Incorporation is available as an exhibit to our 2023 Annual Report on Form 10-K.
Effectiveness
The Proposed Certificate Amendment is binding. If the Proposed Certificate Amendment is approved, it will become effective upon filing of the Proposed Certificate Amendment to our Certificate of Incorporation with the Secretary of State for the State of Delaware.
Board Recommendation
The Board recommends a vote “FOR” this proposal.

PROPOSAL 6: APPROVAL OF AN ADJOURNMENT OF THE ANNUAL MEETING, IF NECESSARY OR APPROPRIATE, TO SOLICIT ADDITIONAL PROXIES
General
We may ask stockholders to vote on a proposal to adjourn the Annual Meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the Annual Meeting to adopt any of the other proposals. In that event, stockholders will be asked to vote only upon this proposal and not on any other matter. If this proposal is approved, the Board may in its discretion, if necessary or appropriate, adjourn, or make one or more successive adjournments of, the Annual Meeting to use the additional time to solicit additional proxies in favor of any of the other proposals. Even if there are a sufficient number of votes at the time of the Annual Meeting to adopt one of the other proposals, the Board may in its discretion seek to, if necessary or appropriate, adjourn the Annual Meeting to solicit additional proxies for the proposal for which there are insufficient votes, and the Board may do so without adopting the proposal for which there are sufficient votes at the time of the Annual Meeting.
Board Recommendation
The Board recommends a vote “FOR” this proposal.

CORPORATE GOVERNANCE
Our business affairs are managed under the direction of our Board. Our Board has adopted a set of Corporate Governance Guidelines as a framework for the governance of the Company, which is posted on our website located at https://ir.spyre.com/corporate-governance under “Governance Documents.”
Our Governance Structure and Philosophy
Our governance practices reflect the environment in which we operate and are designed to support our mission to develop next-generation therapeutics for the treatment of inflammatory bowel disease. Spyre is a newly public, pre-revenue preclinical stage biotechnology company in an evolving industry, with a focus on developing our candidate pipeline through both business development and internal research efforts, and, like other companies in the biotechnology industry, face extreme stock price and volume fluctuations that are often unrelated or disproportionate to our operating performance. With these business environment considerations in mind, the Board believes our current governance structure enables the management team to act with deliberation and to focus on delivering long-term value to stockholders and protect minority investors from the interests of potentially short-sighted investors who may seek to act opportunistically and not in the best interests of the Company or stockholders generally. This structure includes the following elements:
Classified board: our directors serve three-year terms, with approximately 1/3 of the Board (instead of the entire Board) elected at each annual meeting. This helps to provide stability and continuity, permitting directors to develop and share institutional knowledge and focus on the long term, and encourages stockholders to engage directly with the Board and management team regarding significant corporation transactions.
Supermajority voting: the voting standard for most items is a majority of shares present, but 2/3 of the outstanding shares are needed to amend certain provisions of our Certificate of Incorporation and Bylaws and remove directors. This helps protect against a small group of stockholders acting to amend our governing documents or to remove directors for reasons that may not be in the best interests of all stockholders.
Plurality voting for directors: our directors are elected by a plurality of votes cast (instead of a majority of votes cast), meaning the nominees with the most votes are elected. This helps avoid potential disruption to the Board and management team as a result of a “failed election.”
Stockholders cannot call special meetings or act by written consent: stockholders can propose business at each annual meeting (in accordance with our advance notice bylaws and Rule 14a-8) but cannot call a stockholder vote in between annual meetings or act by written consent. This helps avoid unnecessary diversion of Board and management time (potentially at the request of a limited number of stockholders acting to further short-term special interests) from executing on our long-term strategy.
Recognizing that the Company’s operating environment continues to evolve and that governance practices should not be static as a matter of course, the Board annually evaluates our governance structure to confirm it remains in the best interests of the Company and stockholders and values input from our stockholders on this topic.
Board Composition
Director Nomination Process
The Nominating Committee is responsible for, among other things, engaging in succession planning for directors and identifying qualified individuals to become members of the Board to oversee management’s execution of the Company’s strategy and safeguard the long-term interests of stockholders. In this regard, the committee is charged with developing and recommending Board membership criteria to the Board for approval, evaluating the composition of the Board annually to assess the skills and experience that are currently represented on the Board and to assess the criteria that may be needed in the future, and identifying, reviewing the qualifications of and recommending potential director candidates.
In identifying potential candidates for Board membership, the Nominating Committee considers recommendations from directors, stockholders, management and others, including, from time to time, third-party search firms to assist it in locating qualified candidates. Once potential director candidates are identified, the committee, with the assistance of management, undertakes a vetting process that considers each candidate’s background, independence and fit with the
19



Board’s priorities. As part of this vetting process, the committee, as well as other members of the Board and the CEO, may conduct interviews with the candidates. If the committee determines that a potential candidate meets the needs of the Board and has the desired qualifications, it recommends the candidate to the full Board for appointment or nomination and to the stockholders for election at the annual meeting.
Criteria for Board Membership
In assessing potential candidates for Board membership and in assessing Board composition, the Nominating Committee considers a wide range of factors and generally seeks to balance the following skills, experiences and backgrounds on the Board:
Leadership: experience serving in a leadership role of an organization, including driving strategy execution, organizational growth and managing human capital.
Finance & Accounting: experience or expertise in finance, accounting, financial reporting processes and capital markets.
Biotechnology Industry: experience and knowledge of the biotechnology industry, in particular regarding therapeutics for autoimmune and inflammatory diseases.
Clinical Development: experience driving the development of therapeutics, including the design and management of clinical trials.
Drug Approval Planning/Commercialization: experience driving the planning process for new drug approvals, including medical affairs, and managing commercialization operations for approved drug candidates, including product manufacturing, pricing, reimbursement, marketing and distribution.
Corporate Governance: experience, whether currently or in the past, serving on other public company boards of directors.
Operations & Administration: experience managing corporate operations, including in the areas of human resources, legal, regulatory, public relations and product quality.
Portfolio Management: experience managing investments or driving business development, including collaborations, licensing transactions, M&A and joint ventures/partnerships.
Science & Research: expertise or research experience in scientific disciplines related to biotechnology (e.g., biology, chemistry, medicine).
In addition to the above, the Nominating Committee generally believes it is important for all Board members to possess the highest personal and professional ethics, integrity and values, an inquisitive and objective perspective, a sense for priorities and balance, the ability and willingness to devote sufficient time and attention to Board matters, and a willingness to represent the long-term interests of all our stockholders.
Board Diversity
In addition to the factors discussed above, the Board and the Nominating Committee actively seek to achieve a diversity of occupational and personal backgrounds on the Board. The Nominating Committee considers a potential director candidate’s ability to contribute to the diversity of personal backgrounds on the Board, including with respect to gender, race, ethnic and national background, geography, age and sexual orientation. As part of the search process for each new director, the Nominating Committee actively seeks out women and minority candidates to include in the pool from which Board nominees are chosen.
The Nominating Committee assesses its effectiveness in balancing these considerations in connection with its annual evaluation of the composition of the Board. In this regard, our current Board of eight directors includes one director (12.5%) who self-identifies as female.

Stockholder Recommendations for Directors
It is the Nominating Committee’s policy to consider written recommendations from stockholders for director candidates. The committee considers candidates recommended by our stockholders in the same manner as a candidate recommended by other sources. Any such recommendations should be submitted to the committee as described under “Stockholder Communications” and should include the same information required under our Bylaws for nominating a director, as described under “Stockholder Proposals and Director Nominations for Next Year’s Annual Meeting.”
Board Leadership Structure
Mr. Cox serves as our independent Chair of the Board while Dr. Turtle serves as our Chief Executive Officer. We do not have a policy regarding whether the roles of the Chair and the CEO should be separate or combined, and our Board believes that we should maintain our flexibility to select the Chair and CEO and determine the appropriate leadership structure, from time to time, based on criteria that are in our best interests and the best interests of our stockholders. Our Board periodically reviews its leadership structure to evaluate whether the structure remains appropriate for the Company. At any time when the Chair is not independent or there is not a Chair, the independent directors of the Board will designate an independent director to serve as lead independent director for a period of at least one year.
Currently, the roles of Chair and the CEO are separate, and the Chair is an independent director. The Board believes that this structure is appropriate for the Company as the independent Chair’s leadership of the Board and oversight of corporate governance matters enables our CEO to focus on leading the Company’s business and developing our drug candidate pipeline.
The independent directors have the opportunity to meet in executive sessions without management present at every regular Board meeting and at such other times as may be determined by the Chair. The purpose of these executive sessions is to encourage and enhance communication among the independent directors.
The Board believes that its programs for overseeing risk, as described under “Board Risk Oversight,” would be effective under a variety of leadership frameworks. Accordingly, the Board’s risk oversight function did not significantly impact its selection of the current leadership structure.
21



Director Independence
Our Board determines the independence of our directors by applying the applicable rules, regulations and listing standards of Nasdaq Stock Market (“Nasdaq”). These provide that a director is independent only if the Board affirmatively determines that the director does not have a relationship with us which, in the opinion of the Board, would interfere with the exercise of his or her independent judgment in carrying out the responsibilities of a director. They also specify various relationships that preclude a determination of director independence. Such relationships may include employment, commercial, accounting, family and other business, professional and personal relationships.
Applying these standards, our Board reviews the independence of our directors, taking into account all relevant facts and circumstances. After considering the foregoing factors, our Board has determined that the following members of our Board are currently independent: Dr. Henderson, Ms. Stelzer and Messrs. Cox, Albers, Harwin and Kiselak. Dr. Turtle is not independent as he is our CEO, and Mr. McKenna is not independent due to his consulting arrangement with the Company. In addition, Dr. Ivana Magovcevic-Liebisch, Ms. Alison Lawton and Mr. Hunter Smith were independent during the period they each served on the Board.
All members of our Audit Committee, Compensation Committee and Nominating Committee must be independent directors under the applicable rules, regulations and listing standards of Nasdaq. Members of the Audit Committee and Compensation Committee also must satisfy the independence criteria set forth in Rule 10A-3 and Rule 10C, respectively, under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Our Board has determined that all members of our Audit Committee, Compensation Committee and Nominating Committee are independent and satisfy the relevant independence requirements for such committees.
Board Committees
Our Board has a separately designated Audit Committee, Compensation Committee and Nominating Committee, each of which has the composition and responsibilities described below. Members serve on these committees until their resignation or until otherwise determined by our Board. Each of these committees is empowered to retain outside advisors as it deems appropriate, regularly reports its activities to the full Board and has a written charter, which is posted on our website located at https://ir.spyre.com/corporate-governance under “Governance Documents.”

(1) Following the Merger Closing through the end of 2023
Audit Committee. The primary responsibilities of our Audit Committee are to oversee the accounting and financial reporting processes of the Company, including the audits of the Company’s financial statements, the integrity of the financial statements and the annual review of the performance, qualifications and independence of the outside auditor. This includes reviewing the financial information provided to stockholders and others and the adequacy and effectiveness of the Company’s internal controls. The committee also makes recommendations to the Board as to whether financial statements should be included in the Company’s Annual Report on Form 10-K.
Ms. Stelzer qualifies as an “audit committee financial expert,” as that term is defined in the rules and regulations established by the SEC, and all members of the Audit Committee are “financially literate” under Nasdaq listing rules.
Compensation Committee. The primary responsibilities of our Compensation Committee are to periodically review and approve the compensation and other benefits for our executive officers and directors. This includes reviewing and approving corporate goals and objectives relevant to the compensation of our CEO, evaluating the performance of our CEO
22



in light of the goals and objectives and setting or recommending to the Board the CEO’s compensation based on the committee’s evaluation. The committee also oversees the evaluation of other executive officers and sets or recommends to the Board the compensation of such executive officers based upon the recommendation of the CEO, administers and makes recommendations to the Board regarding equity incentive plans that are subject to the Board’s approval and approves the grant of equity awards under the plans and oversees our strategies and policies related to human capital management, including with respect to matters such as diversity and inclusion, workplace environment and culture, and talent development and retention.
The Compensation Committee may delegate its duties and responsibilities to one or more subcommittees. The committee may also delegate authority to review and approve the compensation of our employees to certain of our executive officers. Even where the committee does not delegate authority, our executive officers will typically make recommendations to the committee regarding compensation to be paid to our employees and the size of equity awards under our equity incentive plans but will not be present during voting or deliberations on their own compensation. The committee has the authority to engage outside advisors, such as compensation consultants, to assist it in carrying out its responsibilities. The committee engaged Compensia, Inc. (“Compensia”) and Alpine Rewards, LLC in 2023 (“Alpine”) to provide advice regarding the amount and form of executive and director compensation.
Nominating Committee. The primary responsibilities of our Nominating Committee are to engage in succession planning for the Board, identify individuals qualified to become members of the Board, recommend director candidates to the Board, including for election or reelection to the Board at each annual stockholders’ meeting, and perform a leadership role in shaping the Company’s corporate governance. In addition, the committee is responsible for developing and recommending to the Board criteria for identifying and evaluating qualified director candidates and developing and recommending to the Board a set of corporate governance principles. The committee is also responsible for making recommendations to the Board concerning the size, structure, composition and functioning of the Board and its committees and oversees sustainability maters relevant to the Company’s business, including Company policies, activities and opportunities.
Board Risk Oversight
We believe that risk management is an important part of establishing and executing on the Company’s business strategy. Our Board, as a whole and at the committee level, focuses its oversight on the most significant risks facing the Company and on the Company’s processes to identify, prioritize, assess, manage and mitigate those risks. The committees oversee specific risks within their purview, as follows:
The Audit Committee has overall responsibility for overseeing the Company’s practices with respect to risk assessment and management. Additionally, the committee is responsible for overseeing management of risks related to our financial statements and financial reporting process, compliance and information technology and cybersecurity.
The Compensation Committee is responsible for overseeing management of risks related to our compensation policies and programs and human capital management practices.
The Nominating Committee is responsible for overseeing management of risks related to director succession planning, corporate governance practices and sustainability practices.
Our Board and its committees receive regular reports from members of the Company’s senior management on areas of material risk to the Company, including strategic, operational, financial, legal and regulatory risks. While our Board has an oversight role, management is principally tasked with direct responsibility for assessing and managing risks, including implementing processes and controls to mitigate their effects on the Company.
Other Corporate Governance Practices and Policies
Director Attendance
The Board met 6 times from and after the Merger Closing. Following the Merger Closing through the end of 2023, each member of the Board attended at least 75% of the aggregate number of meetings of the Board and the committees on which he or she served during the period in which he or she was on the Board or committee.
23



Directors are encouraged to attend the annual meeting of stockholders. Our 2024 Annual Meeting of Stockholders will be Spyre's first annual meeting of stockholders as a newly public company following the completion of the Merger.
Stockholder Communications
Stockholders and other interested parties may communicate with our Board or a particular director by sending a letter addressed to the Board or a particular director to our Corporate Secretary at the address set forth on the first page of this Proxy Statement. These communications will be compiled and reviewed by our Corporate Secretary, who will determine whether the communication is appropriate for presentation to the Board or the particular director. The purpose of this screening is to allow the Board to avoid having to consider irrelevant or inappropriate communications (such as advertisements, solicitations and hostile communications).
To enable the Company to speak with a single voice, as a general matter, senior management serves as the primary spokesperson for the Company and is responsible for communicating with various constituencies, including stockholders, on behalf of the Company. Directors may participate in discussions with stockholders and other constituencies on issues where Board-level involvement is appropriate. In addition, the Board oversees the Company’s stockholder engagement efforts.
Code of Business Conduct and Ethics
Our Board has adopted a Code of Business Conduct and Ethics that establishes the standards of ethical conduct applicable to all our directors, officers and employees, including our principal executive officer, principal financial officer and principal accounting officer, or persons performing similar functions. It addresses, among other matters, compliance with laws and policies, conflicts of interest, corporate opportunities, regulatory reporting, external communications, confidentiality requirements, insider trading, proper use of assets and how to report compliance concerns. A copy of the code is available on our website located at https://ir.spyre.com/corporate-governance under “Governance Documents.” We intend to disclose any amendments to the code, or any waivers of its requirements, on our website to the extent required by applicable rules. Our Board is responsible for applying and interpreting the code in situations where questions are presented to it.
Clawback Policy
In October 2023, we adopted a Compensation Recoupment (Clawback) Policy, which is intended to comply with the requirements of Nasdaq Listing Standard 5608 implementing Rule 10D-1 under the Exchange Act. In the event the Company is required to prepare an accounting restatement of the Company’s financial statements due to material non-compliance with any financial reporting requirement under the federal securities laws, the Company will recover, on a reasonably prompt basis, the excess incentive-based compensation received by any covered executive during the prior three fiscal years that exceeds the amount that the executive otherwise would have received had the incentive-based compensation been determined based on the restated financial statements.
Anti-Hedging Policy
We have a policy that prohibits our directors, officers, employees and consultants from engaging in (a) short-term trading; (b) short sales; (c) transactions involving publicly traded options or other derivatives, such as trading in puts or calls with respect to Company securities; and (d) hedging transactions.
Compensation Committee Interlocks
None of the members of our Compensation Committee has at any time during the prior three years been one of our officers or employees. None of our executive officers currently serves, or in the past fiscal year has served, as a member of the board or compensation committee of any entity that has one or more executive officers serving on our Board or Compensation Committee.

Narrative Disclosure to Summary Compensation Table
In October 2023, our Compensation Committee adopted a compensation philosophy to frame future compensation decisions for the Company. Under this philosophy, compensation positioning is used to attract and retain key employees
29



for the Company’s continued success and growth. While market data is helpful to the Compensation Committee in setting compensation framework and guiding decisions, other factors such as general market practices, Company strategy, tenure, performance and criticality are also considered. The compensation philosophy serves as the foundation to reinforce the Company’s business strategy and desired culture, while balancing internal and external alignment.
Peer Group
In October 2023, our Compensation Committee, in consultation with Alpine, its independent compensation consultant, established a peer group that focuses on U.S.-based, pre-clinical or early clinical biopharma companies (with priority places on companies with a similar therapeutic focus) with a market capitalization ranging from $250 million to $2 billion and less than 100 employees. The peer group, which was used in making compensation decisions in connection with Dr. Turtle’s promotion to Chief Executive Officer and in establishing executive compensation for 2024, includes the following companies:
ACELYRIN, Inc.Arcellx, Inc.Kymera Therapeutics, Inc.
Aclaris Therapeutics, Inc.Astria Therapeutics, Inc.Morphic Holding, Inc.
Allakos Inc.Cabaletta Bio, Inc.Pliant Therapeutics, Inc.
Alpine Immune Sciences, Inc.Celldex Therapeutics, Inc.RAPT Therapeutics, Inc.
AnaptysBio, Inc.IGM Biosciences, Inc.Ventyx Biosciences, Inc.
Apogee Therapeutics, Inc.Janux Therapeutics, Inc.Vera Therapeutics, Inc.
Elements of Compensation
Base Salary
Each NEO’s base salary is a fixed annual amount that is intended to compensate the NEO for performing specific job responsibilities and is based on the NEO’s level of experience and requisite skills. Our Compensation Committee annually evaluates and approves (or recommends to the Board for approval for our Chief Executive Officer) each NEO’s base salary. The base salaries for the NEOs hired during 2023 were established in connection with their appointments, and Dr. Turtle’s base salary was subsequently adjusted in connection with his promotion. The table below sets forth the base salary as of December 31, 2023 for each NEO that was employed with us at such time:
Named Executive Officer
Base Salary
as of 12/31/2023
Cameron Turtle$625,000
Scott Burrows$455,000
Heidy King-Jones$470,000
Annual Bonus Program
In light of the strategic process and the Merger, our Compensation Committee and the Board determined not to utilize an annual bonus program for 2023. Instead, our Compensation Committee determined that each NEO who was employed as of the payment date would receive an annual bonus for 2023 equal to their target bonus, pro-rated for any partial years of service.

We maintain a tax-qualified 401(k) defined contribution plan that provides eligible U.S. employees, including our NEOs, with an opportunity to save for retirement on a tax-advantaged basis. Eligible employees may make voluntary contributions from their eligible pay, up to certain applicable annual limits set by the Internal Revenue Code of 1986, as amended. We provide matching contributions equal to 100% of the first 3% of eligible compensation contributed by each employee, and 50% of the next 2% of eligible compensation contributed by each employee. All company matching contributions are immediately and fully vested. We do not maintain, and have not historically maintained, any non-qualified deferred compensation or defined benefit pension plan.
Potential Payments Upon Termination or Change in Control
Pursuant to the terms of the Offer Letters, in the event each NEO that is a current executive officer is terminated by the Company without “cause” or as a result of a resignation for “good reason” (collectively, an “Involuntary Termination”), such NEO will, subject to the execution of a release in favor of the Company, receive: (i) severance payments equal to 12 months of base salary and any earned but unpaid annual bonus for the preceding year; (ii) up to 12 months of partially subsidized COBRA coverage; and (iii) accelerated vesting of any time-based equity awards scheduled to vest in the 12 months following such termination. However, if the Involuntary Termination is within three months before or 12 months after a change in control of the Company, the NEO will instead receive: (A) severance payments equal to 18 months of base salary, any earned but unpaid annual bonus for the preceding year, and the target annual bonus for the year of termination; (B) up to 18 months of fully subsidized COBRA continuation coverage; and (C) full acceleration of all equity awards (with performance-based awards determined in accordance with the terms of the applicable award agreement or, if not specified in such award agreement, based on the greater of target or, if determinable, actual performance).
As used in the Offer Letters:
“Cause” generally means (i) the NEO’s dishonest statements or acts with respect to the Company or any affiliate of the Company, or any current or prospective customers, suppliers, vendors or other third parties with which such entity does business that results in or is reasonably anticipated to result in material harm to the Company; (ii) the NEO’s conviction or plea of no contest to a felony or misdemeanor involving moral turpitude, deceit, dishonesty or fraud; (iii) the NEO’s failure to perform his or her duties or responsibilities, subject to a 30-day cure period; (iv) the NEO’s gross negligence, willful misconduct that results in or is reasonably anticipated to result in material harm to the Company; or (v) the NEO’s violation of any material provision of any agreement with the Company or any written Company policies.
“Good Reason” generally means (i) a material diminution in the NEO’s base salary or target bonus (excluding across-the-board reductions of less than 10%); (ii) a material geographic relocation or requirement to change the NEO’s remote work location; (iii) a material reduction in the NEO’s duties, authority or responsibilities; (iv) the failure of the Company to obtain the assumption of the Offer Letter by a successor; or (v) the material breach of any agreement between the NEO and the Company, in each case, subject to standard notice and cure periods.

Delinquent Section 16(a) Reports
Section 16(a) of the Exchange Act requires our directors, officers and persons who beneficially own more than 10% of a registered class of our equity securities to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock and other equity securities. To our knowledge, based solely on our review of Forms 3, 4
40



and 5 filed with the SEC or written representations that no Form 5 was required, during the year ended December 31, 2023, we believe that all of our directors, officers and persons who beneficially own more than 10% of a registered class of our equity securities timely filed all reports required under Section 16(a) of the Exchange Act, except that, due to administrative errors, one Form 3 and one Form 4 were filed late for Mr. Albers with respect to his ownership of Series A Preferred Stock and the conversion of shares of Series A Preferred Stock into shares of common stock, respectively.

Registration Rights Agreement
On March 16, 2021, we entered into a registration rights agreement (the “Baker RRA”) with the Baker Funds, pursuant to which the Baker Funds are entitled to certain resale registration rights with respect to shares of our common stock held by the Baker Funds (the “Baker Registrable Securities”). Under the Baker RRA, following a request by the Baker Funds, we are obligated to file a resale registration statement on Form S-3, or other appropriate form, covering Baker Registrable Securities. Under the Baker RRA, the Baker Funds also have the right to up to two underwritten public offerings or block trades per calendar year, but no more than three underwritten public offerings and eight block trades in total, to effect the sale or distribution of their Baker Registrable Securities, subject to specified exceptions, conditions and limitations. The Baker RRA also includes customary indemnification obligations in connection with registrations conducted pursuant to the Baker RRA. The Baker RRA has terminated and is no longer in effect.
Paragon Agreement
Paragon and Parapyre Holding LLC (“Parapyre”) each beneficially owns less than 5% of our capital stock through their respective holdings of our common stock. Fairmount beneficially owns more than 5% of our capital stock, has two seats on our Board and beneficially owns more than 5% of Paragon, which is a joint venture between Fairmount and Fair Journey Biologics. Fairmount appointed Paragon’s board of directors and has the contractual right to approve the appointment of any executive officers. Parapyre is an entity formed by Paragon as a vehicle to hold equity in Pre-Merger Spyre in order to share profits with certain employees of Paragon.
In connection with the Merger, we assumed the rights and obligations of Pre-Merger Spyre under that certain antibody discovery and option agreement, dated May 25, 2023 and subsequently amended and restated on September 29, 2023, by and among Spyre Therapeutics, LLC, Paragon and Parapyre (the “Paragon Agreement”), pursuant to which we have exercised the option to acquire intellectual property license rights to or have the option to acquire intellectual property license rights with respect to certain research programs, including with respect to our product candidates. Under the Paragon Agreement, we are obligated to compensate Paragon on a quarterly basis for its services performed under each research program based on the actual costs incurred with mark-up costs pursuant to the terms of the Paragon Agreement. As of the date of the Merger, Pre-Merger Spyre had incurred total expenses of $19.0 million under the Paragon Agreement since inception, inclusive of a $3.0 million research initiation fee that was due upon signing of the Paragon Agreement and
42



$16.0 million of reimbursable expenses under the Paragon Agreement for historical costs incurred by Paragon. As of the Merger Close, $19.0 million was unpaid and was assumed by us through the Merger. Furthermore, following our amendment and restatement of the Paragon Agreement on September 29, 2023, we are obligated to provide certain equity grants to Parapyre pursuant to the Parapyre Option Obligation upon the completion of each of the calendar years ending on December 31, 2023 and December 31, 2024 to purchase 1% of the then outstanding shares of our common stock, on a fully diluted basis, on the last business day of each applicable calendar year, at the fair market value determined by the Board. Following the execution of each of the SPY001 License Agreement and SPY002 License Agreement, we expect to be obligated to pay Paragon up to $22.0 million upon the achievement of specific development, regulatory and clinical milestones for the first product under each agreement, respectively, that achieves such specified milestones. Upon execution of each of the SPY001 License Agreement and SPY002 License Agreement, we expect to pay Paragon a $1.5 million fee for nomination of a development candidate and we expect to be obligated to make a further milestone payment of $2.5 million upon the first dosing of a human patient in a Phase 1 trial. Subject to the execution of the option to acquire the intellectual property rights related to four research programs with respect to the SPY003 or SPY004 research programs pursuant to the Paragon Agreement, we expect to be obligated to make similar payments upon and following the execution of license agreements with respect to these research programs, respectively.
In July 2023 and December 2023, we exercised our option available under the Paragon Agreement with respect to the SPY001 and SPY002 research programs, respectively, and expect to enter into the SPY001 License Agreement and the SPY002 License Agreement. Our option available under the Paragon Agreement with respect to the SPY003 and SPY004 programs remains unexercised.

Related Party Transaction Policy
Our Board has a written policy regarding the review and approval or ratification by our Audit Committee of related person transactions. For purposes of our policy only, a related person transaction is a transaction, arrangement or relationship or any series of similar transactions, arrangements or relationships between us or any of our subsidiaries and any related person in which the aggregate amount involved since the beginning of our last completed fiscal year exceeds or is expected to exceed $120,000 and such related person has or will have a direct or indirect interest. A related person is defined to include any executive officers, directors or director nominees or beneficial owner of more than 5% of our common stock and any immediate family member of any of the foregoing persons. In determining to approve or ratify any such transaction, our Audit Committee is expected to take into account, among other factors it deems appropriate, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar circumstances and the extent of the related person’s interest in the transaction. Transactions involving compensation for services provided to us as an employee or director, among other limited exceptions, are deemed under the terms of the policy to have standing pre-approval by the Audit Committee but may be specifically reviewed if appropriate in light of the facts and circumstances. Any director who is a related person with respect to a transaction under review is not permitted to participate in the deliberations (other than to provide information concerning the transaction to the Audit Committee) or vote on approval of the transaction.

OTHER MATTERS
Stockholder Proposals and Director Nominations for Next Year’s Annual Meeting
Pursuant to Rule 14a-8 of the Exchange Act, stockholders who wish to submit proposals for inclusion in the proxy statement for the 2025 Annual Meeting of Stockholders must send such proposals to our Corporate Secretary at the address set forth on the first page of this Proxy Statement. Such proposals must be received by us as of the close of business (6:00 p.m. Eastern Time) on December 2, 2024 and must comply with Rule 14a-8 of the Exchange Act. The submission of a stockholder proposal does not guarantee that it will be included in the proxy statement.
As set forth in our Bylaws, if a stockholder intends to make a nomination for director election or present a proposal for other business (other than pursuant to Rule 14a-8 of the Exchange Act) at the 2025 Annual Meeting of Stockholders, the stockholder’s notice must be received by our Corporate Secretary at the address set forth on the first page of this Proxy Statement no earlier than the 120th day and no later than the close of business on the 90th day before the anniversary of the last annual meeting; provided, however, that if the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, the stockholder’s notice must be delivered not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the date on which the first public announcement of the date of such annual meeting is made by the Company. Therefore, unless the 2025 Annual Meeting of Stockholders is more than 30 days before or more than 60 days after the anniversary of the Annual Meeting, notice of proposed nominations or proposals (other than pursuant to Rule 14a-8 of the Exchange Act) must be received by our Corporate Secretary no earlier than January 13, 2025 and no later than the close of business on February 12, 2025. Any such director nomination or stockholder proposal must be a proper matter for stockholder action and must comply with the terms and conditions set forth in our Bylaws (which includes the timing and information required under Rule 14a-19 of the Exchange Act). If a stockholder fails to meet these deadlines or fails to satisfy the requirements of Rule 14a-4 of the Exchange Act, we may exercise discretionary voting authority under proxies we solicit to vote on any such proposal as we determine appropriate. We reserve the right to reject, rule out of order or take other appropriate action with respect to any nomination or proposal that does not comply with these and other applicable requirements.
Delivery of Documents to Stockholders Sharing an Address
A number of brokerage firms have adopted a procedure approved by the SEC called “householding.” Under this procedure, certain stockholders who have the same address and do not participate in electronic delivery of proxy materials will receive only one copy of the proxy materials, including this Proxy Statement, the Notice and our Annual Report on Form 10-K for the year ended December 31, 2023, until such time as one or more of these stockholders notifies us that they wish to receive individual copies. This procedure helps to reduce duplicate mailings and save printing costs and postage fees, as well as natural resources. If you received a “householding” mailing this year and would like to have additional copies of the proxy materials mailed to you, please send a written request to our Corporate Secretary at the address set forth on the first page of this Proxy Statement, or call (617) 651-5940, and we will promptly deliver the proxy materials to you. Please contact your broker if you received multiple copies of the proxy materials and would prefer to receive a single copy in the future, or if you would like to opt out of “householding” for future mailings.
Availability of Additional Information
We will provide, free of charge, a copy of our Annual Report on Form 10-K for the year ended December 31, 2023, including exhibits, on the written or oral request of any stockholder of the Company. Please send a written request to our Corporate Secretary at the address set forth on the first page of this Proxy Statement, or call the number above.
