The “Selling Stockholder” refers to GNI USA and its respective permitted transferees. The shares of Common Stock registered by this prospectus are referred to herein as the “Resale Shares.” The Resale Shares (adjusted for the 1 to 15 reverse stock split effected by the Company on October 30, 2023) consist of:
(i)
540,666 shares of Common Stock issued upon conversion of 811 shares of Convertible Preferred Stock effective January 23, 2024, previously issued to GNI USA pursuant to that certain Securities Purchase Agreement, dated October 27, 2023 (the “Securities Purchase Agreement”), by and between the Company and GNI USA; and

We are not offering or selling any shares of Common Stock under this prospectus, and we will not receive any proceeds from the sale of the Resale Shares by the Selling Stockholder pursuant to this prospectus. However, upon any cash exercise of the Warrants by the Selling Stockholder, we will receive cash proceeds per share equal to the exercise price of the Warrants. If the Warrants are exercised in a cashless exercise, we will not receive any proceeds from the exercise of the Warrants. Our registration of the securities covered by this prospectus does not mean that the Selling Stockholder will offer or sell any of the Resale Shares. The Selling Stockholder may sell the Resale Shares covered by this prospectus in a number of different ways and at varying prices. We provide more information about how the Selling Stockholder may sell the Resale Shares in the section entitled “Plan of Distribution.”
If any underwriters, dealers or agents are involved in the sale of any of the Resale Shares, their names and any applicable purchase price, fee, commission or discount arrangement between or among them will be set forth, or will be calculable from the information set forth, in an applicable prospectus supplement. See the sections of this prospectus entitled “About this Prospectus” and “Plan of Distribution” for more information.

PROSPECTUS SUMMARY
You should read the following summary together with the entire prospectus and the documents incorporated by reference herein, including our consolidated financial statements and related notes as well as any free writing prospectus prepared by us or on our behalf. You should carefully consider, among other things, the matters discussed in the sections entitled “Risk Factors” included in or incorporated by reference in this prospectus.
Our Company
We are a financially-sustainable pharmaceutical company with a record of financial success that develops and commercializes small-molecule anti-inflammatory and anti-fibrotic drugs targeting organ diseases, focusing specifically on organ fibrosis. Fibrotic diseases represent a large patient population with significant unmet medical needs. Fibrosis involves a complex, multi-stage process with multiple pathways. While there are numerous potential targets for anti-fibrotic therapy, both established and emerging, addressing a single molecular pathway may not be sufficient to prevent, halt, or reverse fibrosis.
Our strategy is to use our experience in the successful development and commercialization of ETUARY® (Pirfenidone) to expand into new indications and develop similar drug candidates. Pirfenidone, the first anti-fibrotic drug approved for idiopathic pulmonary fibrosis (“IPF”) in Japan, the EU, the United States, and the People’s Republic of China (the “PRC”), is a small molecule drug that inhibits the synthesis of TGF-ß1, TNF-α, and other fibrosis and inflammation modulators. We have obtained approval for ETUARY (pirfenidone) in the PRC for IPF.
Beijing Continent Pharmaceuticals Co., Ltd., a company organized under the laws of the PRC (d/b/a Gyre Pharmaceuticals, Inc.) (“Gyre Pharmaceuticals”) successfully advanced Pirfenidone from research and development to commercialization in the PRC for the treatment of IPF. ETUARY’s annual sales have consistently grown each year, reaching $112.1 million in 2023. In addition to IPF, Pirfenidone is undergoing three additional Phase 3 studies for connective tissue disease associated with interstitial lung disease to broaden its indications and market: sclerosis-related interstitial lung disease, dermatomyositis-related interstitial lung disease and pneumoconiosis.
F351, our lead development candidate, is a structural derivative of ETUARY (Pirfenidone). It is a new oral chemical entity with an anti-fibrotic, TGF-ß1-targeting mechanism of action, for which we hold patents in major markets. Studies suggest that F351 and its major metabolites have minimal drug-drug interaction risks. Despite potential efficacy in IPF, we are prioritizing F351 for the treatment of liver fibrosis due to the large potential addressable market and significant unmet need.
Gyre Pharmaceuticals has completed a Phase 2 trial of F351 in the PRC for chronic hepatitis B (“CHB”)-associated liver fibrosis. The Phase 2 trial showed that F351 was well-tolerated without notable toxicity and patients treated showed statistically-significant improvement of liver fibrosis, with the best efficacy results achieved at 270 mg/day dosing. Based on these results, a confirmatory Phase 3 trial is ongoing in the PRC. The enrollment of 248 patients for the confirmatory Phase 3 trial has been completed, with last patient out expected in 2024 and clinical results expected by early 2025.
In the United States, we have completed a Phase 1 clinical trial of F351 in healthy volunteers. We are preparing an investigational new drug (an “IND”) application and expect to submit it in late 2024. Following results from the PRC Phase 3 trial in CHB-associated liver fibrosis and pending approval of our IND, we expect to initiate a Phase 2a trial to evaluate F351 for the treatment of nonalcoholic associated steatohepatitis-associated liver fibrosis in 2025.
Corporate Information
We were incorporated in Delaware in 1997 as a wholly-owned subsidiary of R.J. Reynolds Tobacco Company. In August 2000, we became an independent company when we issued and sold stock to venture capital investors. On August 20, 2015, pursuant to the merger agreement between Targacept, Inc. and Catalyst Biosciences, Inc. (“Private Catalyst”), we acquired Private Catalyst and on August 20, 2015, we changed our name from Targacept, Inc. to Catalyst Biosciences, Inc. On October 30, 2023, we consummated a business combination pursuant to which we acquired an indirect controlling interest in Gyre Pharmaceuticals (the “Closing”). At the Closing, we changed our name from Catalyst Biosciences, Inc. to Gyre Therapeutics, Inc. Our principal executive offices are located at 12770 High Bluff Drive, Suite 150, San Diego, CA 92130, and our telephone number is (858) 567-7770. Our website

On October 30, 2023, Dr. Luo and Mr. Eastling were appointed to the Nominating and Corporate Governance Committee of the Board, and Dr. Luo was appointed the chair of the committee.

Except as disclosed herein, the Selling Stockholder does not have, and within the past three years has not had, any position, office or other material relationship with us.
For the Selling Stockholder listed on the table below, we have calculated the maximum estimated number of Resale Shares that could become saleable by such Selling Stockholder pursuant to this prospectus based on: (i) 540,666 shares of Common Stock issued upon conversion of 811 shares of Convertible Preferred Stock effective January 23, 2024, previously issued to GNI USA pursuant to the Securities Purchase Agreement; and (ii) 540,666 shares of Common Stock issuable upon conversion of 811 shares of Convertible Preferred Stock issuable upon the exercise of the Warrants. On an aggregate basis, the total number of the Resale Shares saleable pursuant to this prospectus is 1,081,332 shares.
For purposes of the table below, we have assumed that the Selling Stockholder will not acquire beneficial ownership of any additional securities during the offering. The following table is prepared based on information provided to us by the Selling Stockholder. In addition, we assume that the Selling Stockholder has not sold, transferred or otherwise disposed of, our Common Stock in transactions exempt from the registration requirements of the Securities Act. Any changed or new information given to us by the Selling Stockholder, including regarding the identity of, and the securities held by, each Selling Stockholder, will be set forth in a prospectus supplement or amendments to the registration statement of which this prospectus is a part, if and when necessary.

Except in cases where community property laws apply or as indicated in the footnotes to this table, to our knowledge, each Selling Stockholder identified in the table possesses sole voting and investment power over the Resale Shares shown as beneficially owned by the Selling Stockholder. The information is not necessarily indicative of beneficial ownership for any other purpose.

TABLE OF CONTENTS

PLAN OF DISTRIBUTION
The Selling Stockholder may sell all or a portion of the Resale Shares covered by this prospectus from time to time. The Selling Stockholder will act independently of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made directly or through one or more underwriters, broker-dealers or agents. If the Resale Shares are sold through underwriters or broker-dealers, the Selling Stockholder will be responsible for underwriting discounts or commissions or agent’s commissions. The Resale Shares may be sold on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale, in the over-the-counter market or in transactions otherwise than on these exchanges or systems or in the over-the-counter market and in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions. The Selling Stockholder may use any one or more of the following methods when selling the Resale Shares:
on the Nasdaq, in the over-the-counter market or on any other national securities exchange on which our securities are listed or traded;
in privately negotiated transactions;
in underwritten offerings;
in ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
in a block trade in which the broker-dealer will attempt to sell the offered shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;
through purchases by a broker-dealer as principal and resale by the broker-dealer for its account pursuant to this prospectus;
through the writing of options (including put or call options), whether the options are listed on an options exchange or otherwise;
through the distribution of the shares by any Selling Stockholder to its partners, members or stockholders;
in short sales entered into after the effective date of the registration statement of which this prospectus is a part;
by pledge to secured debts and other obligations;
through delayed delivery arrangements;
an exchange distribution in accordance with the rules of the applicable exchange;
through delayed delivery arrangements;
to or through underwriters or agents;
“at the market” or through market makers or into an existing market for the securities;
through trading plans entered into by a Selling Stockholder pursuant to Rule 10b5-1 under the Exchange Act that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of securities on the basis of parameters described in such trading plans; or
a combination of any such methods of sale.
The Selling Stockholder also may resell all or a portion of the Resale Shares in open market transactions in reliance upon Rule 144 under the Securities Act, as permitted by that rule, or Section 4(a)(1) under the Securities Act, if available, rather than under this prospectus, provided that they meet the criteria and conform to the requirements of those provisions.
Broker-dealers engaged by the Selling Stockholder may arrange for other broker-dealers to participate in sales. If the Selling Stockholder effects such transactions by selling the Resale Shares to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the Selling Stockholder or commissions from purchasers of the
12

TABLE OF CONTENTS

Resale Shares for whom they may act as agent or to whom they may sell as principal. Such commissions will be in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction will not be in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.01.
The Selling Stockholder may transfer and donate the Resale Shares in other circumstances in which case the transferees, donees or pledgees will be the selling beneficial owners for purposes of this prospectus.
Any broker-dealer or agents participating in the distribution of the Resale Shares may be deemed to be “underwriters” within the meaning of Section 2(11) of the Securities Act in connection with such sales. In such event, any commissions paid, or any discounts or concessions allowed to, any such broker-dealer or agent and any profit on the resale of the Resale Shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.
The Selling Stockholder may also sell our securities short and deliver the securities to close out their short positions or loan or pledge the securities to broker-dealers that in turn may sell the securities. The shares may be sold directly or through broker-dealers acting as principal or agent or pursuant to a distribution by one or more underwriters on a firm commitment or best-efforts basis. The Selling Stockholder may also enter into hedging transactions with broker-dealers. In connection with such transactions, broker-dealers of other financial institutions may engage in short sales of our securities in the course of hedging the positions they assume with the Selling Stockholder. The Selling Stockholder may also enter into options or other transactions with broker-dealers or other financial institutions, which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).
Each Selling Stockholder has informed the Company that it is not a registered broker-dealer and does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the Resale Shares. Upon the Company being notified in writing by a Selling Stockholder that any material arrangement has been entered into with a broker-dealer for the Resale Shares through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, a supplement to this prospectus will be filed, if required, pursuant to Rule 424(b) under the Securities Act, disclosing (i) the name of each such Selling Stockholder and of the participating broker-dealer(s), (ii) the number of Resale Shares involved, (iii) the price at which the Resale Shares were sold, (iv) the commissions paid or discounts or concessions allowed to such broker-dealer(s), where applicable, (v) that such broker-dealer(s) did not conduct any investigation to verify the information set out or incorporated by reference in this prospectus, and (vi) other facts material to the transaction.
Under the securities laws of some U.S. states, shares of our Common Stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some U.S. states shares of our Common Stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.
There can be no assurance that any Selling Stockholder will sell any or all of the Resale Shares registered pursuant to the shelf registration statement, of which this prospectus is a part.
Each Selling Stockholder and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including, without limitation, to the extent applicable, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the Resale Shares by the Selling Stockholder and any other participating person. To the extent applicable, Regulation M may also restrict the ability of any person engaged in the distribution of the Resale Shares to engage in market-making activities with respect to the Resale Shares. All of the foregoing may affect the marketability of the Resale Shares and the ability of any person or entity to engage in market-making activities with respect to the Resale Shares.
The Selling Stockholder will pay all of the expenses incurred in connection with the registration of the Resale Shares, including, without limitation, SEC filing fees and expenses of compliance with state securities or “blue sky” laws, all underwriting discounts and selling commissions, if any, and any legal or other expenses incurred by us or them in connection with the registration and offer and sale of the Resale Shares.

ITEM 15.
Indemnification of Directors and Officers.
The Company is a Delaware corporation. Section 145(a) of the Delaware General Corporation Law (the “DGCL”) provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of the corporation, by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.
Section 145(b) of the DGCL provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person acted in any of the capacities set forth above, against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in, or not opposed to, the best interests of the corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation, unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine, upon application, that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.
Further subsections of DGCL Section 145 provide that:
(1)
to the extent a present or former director or officer of a corporation has been successful on the merits or otherwise in the defense of any action, suit or proceeding referred to in subsections (i) and (ii) of Section 145 or in the defense of any claim, issue or matter therein, such person shall be indemnified against expenses, including attorneys’ fees, actually and reasonably incurred by such person in connection therewith;
(2)
the indemnification and advancement of expenses provided for pursuant to Section 145 shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, vote of shareholders or disinterested directors or otherwise; and
(3)
the corporation shall have the power to purchase and maintain insurance of behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would have the power to indemnify such person against such liability under Section 145.
II-1

TABLE OF CONTENTS

As used in this Item 14, the term “proceeding” means any threatened, pending or completed action, suit or proceeding, whether or not by or in the right of the Company, and whether civil, criminal, administrative, investigative or otherwise.
Section 145 of the DGCL makes provision for the indemnification of officers and directors in terms sufficiently broad to indemnify officers and directors of the Company under certain circumstances from liabilities (including reimbursement for expenses incurred) arising under the Securities Act. The Company’s Fourth Amended and Restated Certificate of Incorporation, as amended (the “Certificate of Incorporation”) and Amended and Restated Bylaws provide, in effect, that, to the fullest extent and under the circumstances permitted by Section 145 of the DGCL, the Company will indemnify any and all of its officers and directors. The Company has entered into indemnification agreements with its officers and directors. The Company may, in its discretion, similarly indemnify its employees and agents. The Company’s Certificate of Incorporation also relieves the Company’s directors from monetary damages to the Company or its shareholders for breach of such director’s fiduciary duty as a director to the fullest extent permitted by the DGCL. Under Section 102(b)(7) of the DGCL, a corporation may relieve its directors from personal liability to such corporation or its shareholders for monetary damages for any breach of their fiduciary duty as directors except (i) for a breach of the duty of loyalty, (ii) for failure to act in good faith, (iii) for intentional misconduct or knowing violation of law, (iv) for willful or negligent violations of certain provisions in the DGCL imposing certain requirements with respect to stock repurchases, redemptions and dividends or (v) for any transactions from which the director derived an improper personal benefit.
The Company has purchased insurance policies that, within the limits and subject to the terms and conditions thereof, cover certain expenses and liabilities that may be incurred by directors and officers in connection with proceedings that may be brought against them as a result of an act or omission committed or suffered while acting as a director or officer of the Company.
The underwriting agreements that we may enter into may provide for the indemnification by the underwriters of us and our officers and directors for certain liabilities, including liabilities arising under the Securities Act, and afford certain rights of contribution with respect thereto.

ITEM 17.
Undertakings.
The undersigned registrant hereby undertakes:
(a)
(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i)
to include any prospectus required by Section 10(a)(3) of the Securities Act;
(ii)
to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and
II-4

TABLE OF CONTENTS

(iii)
to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.
(2)
That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3)
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(4)
That, for the purpose of determining liability under the Securities Act to any purchaser:
(i)
Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
(ii)
Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
(5)
That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
(i)
Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
(ii)
Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
(iii)
The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
(iv)
Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.
II-5

TABLE OF CONTENTS

(6)
The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(7)
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
(8)
That, for purposes of determining any liability under the Securities Act, (i) the information omitted from the form of prospectus filed as part of the registration statement in reliance upon Rule 430A and contained in the form of prospectus filed by the registrant pursuant to Rule 424(b)(l) or (4) or 497(h) under the Securities Act shall be deemed to be a part of the registration statement as of the time it was declared effective; and (ii) each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(9)
To file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Trust Indenture Act.

Re:

In arriving at the opinion expressed below, we have examined originals, or copies certified or otherwise identified to our satisfaction as being true and complete copies of the originals, of the specimen common stock certificates and such other documents, corporate records, certificates of officers of the Company and of public officials and other instruments as we have deemed necessary or advisable to enable us to render these opinions.  In our examination, we have assumed the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as copies.

Based on the foregoing, and subject to the assumptions, exceptions, qualifications and limitations set forth herein, we are of the opinion that the Shares, when issued against payment therefor as set forth in the Registration Statement, will be validly issued, fully paid and non-assessable.

We consent to the filing of this opinion as an exhibit to the Registration Statement, and we further consent to the use of our name under the caption “Legal Matters” in the Registration Statement and the prospectus that forms a part thereof.  In giving these consents, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission.

Very truly yours,

EXHIBIT 99.1

UNAUDITED PRO FORMA CONDENSED FINANCIAL INFORMATION

On October 30, 2023, Gyre Therapeutics, Inc. (the “Company” or “Gyre”, previously known as Catalyst Biosciences, Inc. or “Catalyst”) consummated the transactions (the “Contributions”) contemplated by the Business Combination Agreement as described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “Annual Report”), which were accounted for as a reverse asset acquisition and a purchase of noncontrolling interest in accordance with United States generally accepted accounting principles (“GAAP”). Continent Pharmaceuticals Inc. (“CPI”) was treated as the accounting acquirer of the reverse asset acquisition and is presented as the predecessor for post-acquisition financial reporting purposes.

Pursuant to Article 11 of Regulation S-X, the Company prepared the following unaudited pro forma condensed combined financial information and the accompanying notes, reflecting the combined financial results of operations of Catalyst and CPI for the year ended December 31, 2023, assuming that the Contributions took place as of January 1, 2023.

The unaudited pro forma condensed combined financial information, including the notes thereto, should be read in conjunction with the following historical financial statements and the accompanying notes:

 
the historical unaudited condensed financial statements of Catalyst as of and for the nine months ended September 30, 2023, included in Catalyst’s Quarterly Report on Form 10-Q (the “10-Q”) filed with the SEC on October 26, 2023 and incorporated by reference; and
 
 
 
 
the Annual Report filed with the SEC on March 27, 2024 and incorporated by reference.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED STATEMENT OF OPERATIONS

 
 1.
 Basis of Pro Forma Presentation

The unaudited pro forma condensed combined financial information was prepared in accordance with U.S. GAAP and pursuant to Article 11 of Regulation S-X. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2023, gives effect to the Contributions as if they had been consummated on January 1, 2023, and has aggregated:

 
a)
Catalyst’s operations for the nine months ended September 30, 2023 from the 10-Q, and

 
b)
the Company’s consolidated operations from the Annual Report, which includes CPI’s operations for the year ended December 2023, and Gyre’s operations post-merger from October 30, 2023 to December 31, 2023.

The Company determined that there were no significant transactions within Catalyst from October 1 to October 30, 2023. The acquired assets and assumed liabilities upon closing of the Contributions were mainly in-process research and development (“IPR&D”), in addition to the working capital. Therefore, no pro forma adjustments, other than weighted average shares outstanding and loss per share, were deemed necessary.

 
 2.
Proforma Adjustments

(A) The weighted average shares outstanding for the period has been calculated as if the Contributions occurred on January 1, 2023, including:

 
(1)
the weighted average shares outstanding for common stock deemed issued to Catalyst upon closing of the Contributions, for the period from October 1 to October 30, 2023, adjusted for the 1-for-15 reverse stock split completed on October 30, 2023 (the “Reverse Stock Split”);

 
(2)
the weighted average shares outstanding for common stock issued to certain minority shareholders upon the closing of the Contributions, for the period from October 1 to October 30, 2023, as adjusted for the Reverse Stock Split.

The Company’s Series A Convertible Preferred Stock, stock options and warrants are determined to be anti-dilutive and, therefore, were excluded from the diluted loss per share attributable to common stock calculation because including them would have been anti-dilutive.

The shares of common stock will be offered for resale by GNI USA, Inc. (the “Selling Stockholder”) pursuant to the prospectus contained in the registration statement to which this exhibit is attached. The registration statement registers the resale of an aggregate of 1,081,332 shares of the registrant’s common stock, consisting of (i) 540,666 shares of the registrant’s common stock issued upon the conversion of the registrant’s Series X Convertible Preferred Stock, par value $0.001 per share (“Convertible Preferred Stock”) effective January 23, 2024, held by the Selling Stockholder and (ii) 540,666 shares of the registrant’s common stock issuable upon the conversion of Convertible Preferred Stock pursuant to the exercise of warrants issued to the Selling Stockholder. Pursuant to Rule 416 under the Securities Act of 1933, as amended (the “Securities Act”), the shares of common stock being registered hereunder include such indeterminate number of shares of common stock as may be issuable upon stock splits, stock dividends, or other distribution, recapitalization or similar events.
(2)
This estimate is made pursuant to Rule 457(c) of the Securities Act solely for purposes of calculating the registration fee. The proposed maximum offering price per share and maximum aggregate offering price are based upon the average of the high and low sales prices of the registrant’s common stock on May 28, 2024, as reported on The Nasdaq Capital Market.
(3)
The Registrant previously paid $1,027.06 in registration fees with respect to the registration statement on Form S-3 filed on November 13, 2023 (No. 333-275466) (the “Withdrawn Registration Statement”). The Registrant filed a Form RW to withdraw the Withdrawn Registration Statement on November 29, 2023.
