Exhibit 99.1

 1  September 2026  A Global Innovator Expanding And Reinventing Protein Degrader Therapeutics 
 
 This presentation contains “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the United States Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, regarding the current plans, expectations and strategies of Gyre Therapeutics, Inc. and its subsidiaries (“Gyre”), which statements are subject to substantial risks and uncertainties and are based on management’s estimates and assumptions. All statements, other than statements of historical facts included in this presentation, are forward-looking statements, including Gyre’s ability to leverage China operations for discovery, validation and development of therapeutics, clinical development plans, anticipated timelines and milestones of Gyre’s degrader antibody-conjugate platform, CG923308, CG620953, CG009301, CG001419, F351 and ETUARYTM, including the geographic location and timing of anticipated regulatory submissions and approvals, and the potential therapeutic benefits, efficacy, safety and differentiation of such product candidates, and market size and commercial opportunity estimates, Gyre’s plans, objectives, goals, strategies, future events, or intentions relating to Gyre’s products and markets, the safety, efficacy and clinical benefits of Gyre’s product candidates, the anticipated timing and design of any planned and ongoing preclinical studies and clinical trials, Gyre’s research and development efforts, plans and objectives of management for future operations and future results of anticipated product development efforts, potential addressable market size and Gyre’s liquidity and capital resources and business trends. In some cases, you can identify forward-looking statements by terms such as “believe,” “can,” “could,” “anticipate”, “design,” “estimate,” “expect,” “forecast,” “intend,” “may,” “might,” “plan,” “target”, “seek”, “goal”, “assume”, “milestones”, “potential,” “predict,” “objective,” “should,” “strategy,” “will,” “would,” “forthcoming,” or the negative of these terms, and similar expressions that are predictions of or indicate future events and future trends. These forward-looking statements may include express or implied statements relating to: the estimated future financial performance and financial position of Gyre; the therapeutic potential and utility, efficacy and clinical benefits of the product candidates of Gyre; the risk/benefit profile of Gyre’s product candidates; expectations regarding Gyre’s research and development efforts, including geographic location and timing of initiation of clinical trials for Gyre’s product candidates; Gyre’s expectations regarding the advancement of product candidates into IND-enabling studies; and Gyre’s expectations, hopes, beliefs, intentions and strategies; and other statements that are not historical fact. These statements involve known and unknown risks, uncertainties and other factors that could cause Gyre’s actual results to differ materially from the forward-looking statements expressed or implied in this presentation, in addition to those risks and uncertainties, such as the uncertainties inherent in the clinical drug development process, the regulatory approval process, the timing of any regulatory filings, the potential for substantial delays, the risk that earlier study results may not be predictive of future study results, manufacturing risks, competition from other therapies or products and the impacts of current macroeconomic and geopolitical risks. A discussion of these and other factors, is set forth in Gyre’s Annual Report on Form 10-K for the year ended December 31, 2025 filed with the Securities and Exchange Commission (the “SEC”) on March 13, 2026 and elsewhere in such other filings and in Gyre’s periodic reports and subsequent disclosure documents filed with the SEC. Gyre cannot assure you that it will realize the results, benefits or developments that it expects or anticipates or, even if substantially realized, that they will result in the consequences or affect Gyre or its business in the way expected. Forward-looking statements are not historical facts and reflect management’s current views with respect to future events. Given the significant uncertainties, you should evaluate all forward-looking statements in the context of these risks and uncertainties and not place undue reliance on these forward-looking statements as predictions of future events. All forward-looking statements in this presentation apply only as of the date made and are expressly qualified in their entirety by the cautionary statements included in this presentation. Gyre has no intention to publicly update or revise any forward-looking statements to reflect subsequent events or circumstances, except as required by law.  Certain information contained in this presentation and statements made orally during this presentation relate to or is based on studies, publications, surveys and other data obtained from third-party sources and Gyre’s own internal estimates and research. While Gyre believes these third-party studies, publications, surveys and other data to be reliable as of the date of this presentation, it has not independently verified, and makes no representation as to the adequacy, fairness, accuracy or completeness of, any information obtained from third-party sources. In addition, no independent sources have evaluated the reasonableness or accuracy of Gyre’s internal estimates or research, and no reliance should be made on any information or statements made in this presentation relating to or based on such internal estimates and research. This presentation contains trademarks, trade names and service marks of other companies which are the property of their respective owners. This presentation concerns a discussion of investigational drugs that are under preclinical and/or clinical investigation, and which have not yet been approved for marketing by the U.S. Food and Drug Administration. They are currently limited by Federal law to investigational use, and no representations are made as to their safety or effectiveness for the purposes for which they are being investigated.  2  Forward-looking Statements
