Important Notice Regarding the Availability of Proxy Materials for the 2025 Annual Meeting of Stockholders to Be Held on June 4, 2025. The Proxy Statement and Annual Report for the year ended December 31, 2024 are available at www.proxyvote.com.

Forward-Looking Statements. The Proxy Statement contains “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, which statements are subject to substantial risks and uncertainties and are based on estimates and assumptions. All statements other than statements of historical fact included in the Proxy Statement, including statements about the Company’s Board of Directors, corporate governance practices and executive compensation program and equity compensation utilization, are forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “may,” “might,” “will,” “objective,” “intend,” “should,” “could,” “can,” “would,” “expect,” “believe,” “design,” “estimate,” “predict,” “potential,” “plan” or the negative of these terms, and similar expressions intended to identify forward-looking statements. These statements involve known and unknown risks, uncertainties and other factors that could cause our actual results or outcomes 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. The Company expressly disclaims any obligation to update or alter any statements whether as a result of new information, future events or otherwise, except as required by law.

Website References. Website references throughout this document are inactive textual references and provided for convenience only, and the content on the referenced websites is not incorporated herein by reference and does not constitute a part of the Proxy Statement.

We are making these proxy materials available to you in connection with the solicitation of proxies by the Board of Directors (the “Board”) of Gyre Therapeutics, Inc. (“we,” “us,” “our” or the “Company”) for use at the 2025 Annual Meeting of Stockholders (the “Annual Meeting”) to be held virtually on June 4, 2025 at 10:00 a.m. Pacific 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 first being made available to our stockholders beginning on April 21, 2025.

Pursuant to SEC rules, we are furnishing the proxy materials to our stockholders primarily via the Internet instead of mailing printed copies. This process allows us to expedite our stockholders’ receipt of proxy materials, lower the costs of printing and mailing the proxy materials and reduce the environmental impact of our Annual Meeting. If you received a Notice of Internet Availability of Proxy Materials (the “Notice”), you will not receive a printed copy of the proxy materials unless you request one. The Notice provides instructions on how to access the proxy materials for the Annual Meeting via the Internet, how to request a printed set of proxy materials and how to vote your shares.

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.

Only stockholders of record at the close of business on April 10, 2025 (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, 93,742,602 shares of our common stock were issued and outstanding.

If your shares of common stock are registered directly in your name with our transfer agent, Equiniti 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.

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.

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/GYRE2025, enter the 16-digit control number found on your proxy card or Notice, and follow the instructions on the website. If your shares are held in street name and your voting instruction form or Notice 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 or Notice. Otherwise, stockholders who hold their shares in street name should contact their bank, broker or other nominee (preferably at least 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 10:00 a.m. Pacific 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.

The proposals to be voted on at the Annual Meeting are as follows:

The Board recommends that you vote your shares “FOR” each director nominee in Proposal 1 and “FOR” Proposals 2 and 3.

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.

Each share of common stock is entitled to one vote on each proposal to be voted on at the Annual Meeting.

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.

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.

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) or, if you requested paper copies of the proxy materials, by completing and mailing a proxy card or by telephone (at (800) 690-6903).

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.

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.

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.

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.

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.

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:

Your last submitted vote is the one that will be counted.

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.

The holders of one-third 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.

Votes will be counted by Broadridge Financial Solutions, the Inspector of Elections appointed for the Annual Meeting.

A nominee will be elected as a director at the Annual Meeting if the nominee receives a plurality of the votes cast “FOR” his or her 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.

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 these proposals. Abstentions will have the same effect as a vote “AGAINST” these matters. Broker non-votes, if any, will have no effect on the outcome of these matters.

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.

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.

In accordance with our Certificate of Incorporation and Amended and Restated Bylaws (the “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 three Class I director nominees named in this Proxy Statement to serve until the 2028 Annual Meeting of Stockholders and until their successors are duly elected and qualified or until their earlier resignation or removal. Our Board has nominated Gordon Carmichael, Ph.D., Songjiang Ma and Ping Zhang for election to our Board. Dr. Carmichael and Mr. Ma were appointed to the Board in October 2023 in accordance with the Business Combination Agreement. Mr. Zhang was appointed to the Board in January 2025 and was initially identified for a position on our Board by GNI Japan.

Our director nominees have indicated that they are willing and able to serve as directors. However, if any 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.

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, who are up for election at this meeting for a term expiring at the 2028 Annual Meeting of Stockholders; two Class II directors, whose terms expire at the 2026 Annual Meeting of Stockholders; and three Class III directors, whose terms expire at the 2027 Annual Meeting of Stockholders.

The Board recommends a vote “FOR” the election of each of the Class I director nominees set forth above.

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 2026.

The Board recommends a vote “FOR” this proposal.

Our Audit Committee has appointed Grant Thornton Zhitong Certified Public Accountants LLP (“Grant Thornton”) as the Company’s independent registered public accounting firm for the year ending December 31, 2025. In this Proposal 3, we are asking stockholders to vote to ratify this appointment. Representatives of Grant Thornton 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 Grant Thornton 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.

Grant Thornton has served as our independent auditor since November 2023. Prior to the Business Combination Closing, Grant Thornton served as auditor of Gyre Pharmaceuticals and its subsidiaries. The following table summarizes the audit fees billed and expected to be billed by Grant Thornton for the indicated fiscal years and the fees billed by Grant Thornton for all other services rendered during the indicated fiscal years. All services associated with such fees and provided after the Business Combination Closing were pre-approved by our Audit Committee in accordance with the “Pre-Approval Policies and Procedures” described below.

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.

As previously reported on the Current Report on Form 8-K filed with the SEC on November 2, 2023, prior to the Business Combination Closing, EisnerAmper served as the independent registered public accounting firm of Catalyst. On the Business Combination Closing, following the completion of Catalyst’s audit for the year

ended December 31, 2022 and the subsequent interim periods through September 30, 2023, which consisted only of the accounts of Catalyst, and the filing of Catalyst’s Annual Report on Form 10-K for the year ended December 31, 2022 and Catalyst’s Quarterly Reports on Form 10-Q for the quarters ended March 31, 2023, June 30, 2023 and September 30, 2023, the Audit Committee dismissed EisnerAmper as our independent registered public accounting firm.

EisnerAmper’s reports on Catalyst’s (for purposes of this subsection, the “Company”) consolidated financial statements as of and for the years ended December 31, 2022 and 2021 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles, except for the following:

During the years ended December 31, 2022 and 2021, and the subsequent interim period through September 30, 2023, there were: (i) no disagreements, within the meaning of Item 304(a)(1)(iv) of Regulation S-K and the related instructions, between Catalyst and EisnerAmper on any matters of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to EisnerAmper’s satisfaction, would have caused EisnerAmper to make reference thereto in its reports; and (ii) no “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K.

Catalyst requested that EisnerAmper furnish a letter addressed to the SEC stating whether or not it agrees with the above statements. A copy of such letter, dated November 2, 2023, was filed as Exhibit 16.1 to the Current Report on Form 8-K filed with the SEC on November 2, 2023.

On the Business Combination Closing, the Audit Committee engaged Grant Thornton as our independent registered public accounting firm.

During the years ended December 31, 2022 and 2021, and the subsequent interim period through September 30, 2023, neither the Company nor anyone on its behalf has consulted with Grant Thornton regarding: (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, and neither a written report nor oral advice was provided to the Company that Grant Thornton concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing, or financial reporting issue; (ii) any matter that was the subject of a disagreement within the meaning of Item 304(a)(1)(iv) of Regulation S-K and the related instructions; or (iii) any reportable event within the meaning of Item 304(a)(1)(v) of Regulation S-K.

The Audit Committee has reviewed and discussed the audited financial statements for the year ended December 31, 2024 with the Company’s management and with Grant Thornton, the Company’s independent registered public accounting firm. The Audit Committee has discussed with Grant Thornton the matters required to be discussed by the applicable standards of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The Audit Committee has also received the written disclosures and the letter from Grant Thornton pursuant to applicable PCAOB requirements regarding its communications with the Audit Committee concerning independence, and the Audit Committee has discussed with Grant Thornton its independence. Based on the foregoing, the Audit Committee recommended to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 for filing with the SEC.

This report is provided by the following directors, who serve on the Audit Committee:

The Board recommends a vote “FOR” this proposal.

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.gyretx.com/corporate-governance/governance-highlights under “Governance Documents.”

Because GNI Japan controls a majority of the voting power of our outstanding common stock, we qualify as a “controlled company” within the meaning of the corporate governance standards of The Nasdaq Stock Market LLC (“Nasdaq”). Under these rules, we may elect not to comply with certain corporate governance requirements, including the requirements that a majority of our Board consist of independent directors and director nominees be selected or recommended to our Board entirely by independent directors. We rely on these exemptions. As a result, our Board does not consist of a majority of independent directors and director nominees are not selected or recommended to our Board by entirely independent directors.

The Nominating Committee is responsible for, among other things, discuss succession planning for the Board and key leadership roles on the Board and its committees, 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 Board’s priorities. As part of this vetting process, the committee, as well as other members of the Board and the Chief Executive Officer (“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.

In assessing potential candidates for Board membership and in assessing Board composition, the Nominating Committee considers a wide range of factors, including directors’ experience, knowledge, understanding of our business environment and specific skills they may possess that are helpful to the Company (including leadership experience, financial expertise and industry knowledge). The committee generally seeks to balance the experiences, skills and characteristics represented on the Board and does not assign specific weight to any of these factors. In addition, 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.

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.”

We do not have a policy regarding whether the roles of the Executive Chair of the Board (“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 may, but are not required to, designate an independent director to serve as lead independent director.

Currently, the roles of Chair and the CEO are separate, the Chair is not an independent director and the Board has not designated a lead independent director. Mr. Zhang, an executive director of GNI Japan (which controls a majority of the voting power of our outstanding common stock), serves as our Chair of the Board while Dr. Ying serves as our Chief Executive Officer. The Board believes that this structure is appropriate for the Company as it reflects the Company’s status as a controlled company and the Chair’s leadership of the Board and oversight of corporate governance matters enables our CEO to focus on leading the Company’s business.

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.

Our Board determines the independence of our directors by applying the applicable rules, regulations and listing standards of 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: Drs. Carmichael, Epstein and Parry and Mr. Nussbaum. Mr. Eastling is not independent as he is married to the Company’s Chief Financial Officer, Mr. Ma is not independent as he is our President, Dr. Ying is not independent as he is our Chief Executive Officer and Mr. Zhang is not independent as he is an executive director of GNI Japan. Dr. Nassim Usman was previously determined to be independent during the period he served on the Board in 2024. Dr. Ying Luo was previously determined not to be independent during the period he served on the Board in 2024 as he was President and Chief Executive Officer of GNI Japan during that period. Dr. Charles Wu was previously determined not to be independent during the period he served on the Board in 2024 as he was our Chief Executive Officer during that period.

All members of our Audit Committee must be independent directors under the applicable rules, regulations and listing standards of Nasdaq. Members of the Audit Committee also must satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We are electing not to avail ourselves of the controlled company exemption for compensation committees, and, as a result all members of our Compensation Committee must be independent directors under the applicable rules, regulations and listing standards of Nasdaq and must satisfy the independence criteria set forth in Rule 10C under the Exchange Act. Our Board has determined that all members of our Audit Committee and Compensation Committee are independent and satisfy the relevant independence requirements for such 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.gyretx.com/corporate-governance/governance-highlights under “Committee Charters.”

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

Mr. Nussbaum 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 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 and 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.

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 Aon/Radford in 2024 to provide advice regarding the amount and form of executive and director compensation.

Nominating Committee. The primary responsibilities of our Nominating Committee are to discuss succession planning for the Board and key leadership roles on the Board and its committees, 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.

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:

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.

During the year ended December 31, 2024, the Board met four times. During 2024, 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.

Directors are encouraged to attend the annual meeting of stockholders. All but one of our directors then serving on the Board attended the 2024 Annual Meeting of Stockholders.

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).

As a general matter, the management team, including the CEO, President, Chief Financial Officer and Chief Operating Officer, serve as the primary spokespersons for the Company and are 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.

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.gyretx.com/corporate-governance/governance-highlights 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.

We have an Incentive Compensation Clawback Policy that 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 amount of any incentive-based compensation received by any covered executive after October 30, 2023 and 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.

We have adopted insider trading policies and procedures governing the purchase, sale and/or other dispositions of our securities by our directors, officers and employees, and other covered persons, as well as the Company itself, that we believe are reasonably designed to promote compliance with insider trading laws, rules and regulations, and Nasdaq listing standards, as applicable.

As part of these policies and procedures, we prohibit 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.

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.

The following table provides information for the year ended December 31, 2024 regarding all compensation awarded to, earned by or paid to each person who served as a non-employee director for some portion of 2024. Employees who served on our Board during 2024 did not receive additional compensation for such service.

Each of our non-employee directors receives compensation pursuant to the non-employee director cash and equity compensation program adopted by our Board. This program provides for the following annual cash retainers:

In addition, each non-employee director who initially joins our Board receives an initial grant of stock options to purchase 52,000 shares of our common stock. The initial stock option grants vest in equal monthly installments over three years.

Each non-employee director who is serving as of the date of the Annual Meeting will receive a grant of stock options to purchase 26,000 shares of our common stock. Annual stock option grants vest in equal monthly installments over one year.

In addition, all non-employee directors are reimbursed their reasonable travel expenses incurred in attending board and committee meetings.

Biographical and other information regarding our executive officers, who are appointed by the Board and serve at the Board’s discretion, is set forth below. Other than Ms. Chen and Mr. Eastling, who are husband and wife, there are no family relationships among any of our directors or executive officers.

He further obtained his executive M.B.A. degree from China Europe International Business School in the PRC in August 2021.

As a smaller reporting company, we have opted to comply with the scaled executive compensation disclosure rules applicable to smaller reporting companies, which requires compensation disclosure for our principal executive officer during 2024 and each of our two other most highly compensated executive officers during 2024. We refer to these individuals as “named executive officers” or “NEOs.” For the year ended December 31, 2024, our named executive officers and the positions each held as of December 31, 2024 were:

The following table presents all of the compensation awarded to, earned by or paid to our named executive officers for the years ended December 31, 2024 and 2023.

For the year ended December 31, 2024, the compensation for each named executive officer generally consisted of a base salary, performance-based bonus, standard employee benefits, and grants of stock options under the Company’s equity plan. These elements (and the amounts of compensation and benefits under each element) were selected because the Company believes they are necessary to help attract and retain executive talent which is fundamental to its success. Below is a more detailed summary of the current executive compensation program as it relates to the Company’s named executive officers.

The named executive officers receive a base salary to compensate them for services rendered to the Company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role, and responsibilities. Each named executive officer’s initial base salary was provided in his or her employment agreement, as applicable, and the base salaries of our executives are generally reviewed and, if appropriate, adjusted on an annual basis.

The table below sets forth the base salary as of December 31, 2024 for each NEO that was employed with us at such time:

The actual base salary paid to each named executive officer for the year ended 2024 is set forth above in the Summary Compensation Table in the column entitled “Salary.”

The Company maintains a cash-based incentive compensation program in which certain of its employees, including its named executive officers, are eligible to receive bonuses based on business and performance goals. Such awards are designed to incentivize the named executive officers with a variable level of compensation that is based on performance measures established by the Company’s Compensation Committee that are tied to pre-defined business and personal goals and objectives.

In 2024, Mr. Ying and Ms. Chen were each eligible to earn annual cash bonuses targeted at 10% of their respective base salaries. The Compensation Committee approved annual bonuses for Mr. Ying and Ms. Chen in the amounts of $35,000 and $25,000, respectively. Mr. Ye earned variable compensation in respect of 2024 performance in the aggregate amount of $168,499.

The Company maintains the Gyre Therapeutics, Inc. 2023 Omnibus Incentive Plan, referred to as the 2023 Plan, in order to facilitate the grant of equity incentives to directors, employees (including the named executive officers), consultants and other service providers of the Company and its affiliates to obtain and retain the services of these individuals, which is essential to its long-term success.

The Company has entered into employment agreements with each Dr. Ying, Ms. Chen and Mr. Ye the key terms of which are described below.

As discussed above, Dr. Wu retired and resigned from his position as Chief Executive Officer effective on January 15, 2024. The Board appointed Dr. Ying Chief Executive Officer of the Company, effective January 15, 2024. In connection with his appointment, the Company entered into an employment agreement with Dr. Ying (the “Ying Employment Agreement”), pursuant to which he is entitled to an annual base salary of $350,000 and eligibility for an annual performance bonus based on the Company’s achievement of targets and milestones as determined by the Company’s board of directors. In addition, Dr. Ying is subject to (i) a non-solicitation restriction covering the Company’s employees and consultants for a period of 12 months following his termination of employment with the Company for any reason, (ii) a perpetual non-disparagement restriction, and (iii) a perpetual restriction on his disclosure of the Company’s confidential information.

In connection with her appointment as Interim Chief Financial Officer on October 30, 2023, the Company entered into an employment agreement with Ms. Chen (the “Chen Employment Agreement”). The Chen Employment Agreement provides that Ms. Chen is entitled to an initial annual base salary of $250,000 and eligibility for an annual performance bonus based on the Company’s achievement of targets and milestones as determined by the Board or the Compensation Committee. In addition, pursuant to the Chen Employment Agreement, Ms. Chen is subject to (i) a non-solicitation restriction covering the Company’s employees and consultants for a period of 12 months following her termination of employment with the Company for any reason, (ii) a perpetual non-disparagement restriction, and (iii) a perpetual restriction on her disclosure of the Company’s confidential information.

Mr. Ye is party to a standard labor contract with Gyre Pharmaceuticals, which generally provides for a monthly base salary and eligibility for standard welfare and retirement benefits.

The following table sets forth information regarding equity awards held by our named executive officers as of December 31, 2024.

The Company maintains a tax-qualified 401(k) retirement savings plan for its employees in the United States, including Ms. Chen, who satisfy certain eligibility requirements. The named executive officers are eligible to participate in the 401(k) plan on the same terms as other full-time employees, including matching contributions equal to 100% of the first 4% of applicable employee contributions. The Company does not maintain any defined benefit pension plans or nonqualified deferred compensation plans.

Mr. Ye participates in the statutorily required pension plan in China, pursuant to which we make contributions of a percentage of Mr. Ye’s base salary on the same terms as other full-time employees based in China.

All of the Company’s full-time employees in the United States are eligible to participate in health and welfare plans, including medical, dental and vision benefits, short-term and long-term disability insurance and life insurance.

The Company believes the benefits described above are necessary and appropriate to provide a competitive compensation package to its employees, including the named executive officers.

Pursuant to the terms of each of the Ying Employment Agreement and the Chen Employment Agreement, upon the termination of, as applicable, Dr. Ying’s or Ms. Chen’s employment by the Company without “Cause” or by the applicable NEO for “Good Reason”, then such NEO will be entitled, in addition to any accrued amounts and subject to the execution and non-revocation of a general release of claims in favor of the Company, to (i) twelve (12) months’ salary continuation, (ii) up to 12 months of partially subsidized COBRA coverage, and (iii) accelerated vesting of any outstanding equity awards scheduled to vest in the twelve (12) month period immediately following such termination.

As used in each of the Ying Employment Agreement and the Chen Employment Agreement:

Dr. Wu was not entitled to, nor did he receive, any severance or other termination-related payments in connection with his retirement and resignation from the Company on January 15, 2024.

In accordance with Item 402(v) of Regulation S-K, we are providing the following descriptions of the relationships between information presented in the Pay Versus Performance table above.

The following table sets forth information, to the extent known by us or ascertainable from public filings, with respect to the beneficial ownership of our common stock as of March 12, 2025 by:

each person, or group of affiliated persons, who is known by us to beneficially owner of greater than 5% of our common stock.

The column entitled “Shares Beneficially Owned” is based on a total of 93,612,442 shares of our common stock outstanding as of March 12, 2025.

Beneficial ownership is determined in accordance with the rules and regulations of the SEC and includes voting or investment power with respect to our common stock. Shares of our common stock subject to options that are currently exercisable or exercisable within 60 days of the date of this table are considered outstanding and beneficially owned by the person holding the options for the purpose of calculating the percentage ownership of that person but not for the purpose of calculating the percentage ownership of any other person. Except as otherwise noted, the persons and entities in this table have sole voting and investing power with respect to all of the shares of our common stock beneficially owned by them, subject to community property laws, where applicable. Except as otherwise indicated in the table below, addresses of named beneficial owners are in care of Gyre Therapeutics, Inc., 12770 High Bluff Drive, Suite 150, San Diego, CA 92130.

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 and 5 filed with the SEC or written representations that no Form 5 was required, during the year ended December 31, 2024, 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.

The following table presents information as of December 31, 2024 with respect to compensation plans under which shares of our common stock may be issued.

Other than the executive officer and director compensation arrangements discussed above under “Corporate Governance—Director Compensation” and “Executive Compensation,” below we describe the transactions to which we were a party since January 1, 2023, in which the amount involved exceeded $120,000 and in which our directors, executive officers, holders of more than 5% of our common stock, or members of their immediate family had a direct or indirect material interest.

We have entered into indemnification agreements with each of its directors and executive officers. Each indemnification agreement provides for indemnification and advancements by us of certain expenses and costs relating to claims, suits or proceedings arising from each individual’s service to us as an officer or director, as applicable, to the maximum extent permitted by applicable law.

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.

Pursuant to Rule 14a-8 of the Exchange Act, stockholders who wish to submit proposals for inclusion in the proxy statement for the 2026 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 22, 2025 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 2026 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 (6:00 p.m. Eastern Time) 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 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 2026 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 February 4, 2026 and no later than the close of business on March 6, 2026. 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.

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, 2024, 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 (858) 567-7770, 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.

We will provide, free of charge, a copy of our Annual Report on Form 10-K for the year ended December 31, 2024, including exhibits, upon 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.
