GYRE THERAPEUTICS, INC.

In this section, unless otherwise specified, references to we, our, us and our company refer to Gyre Therapeutics, Inc. and our majority indirectly owned subsidiary, Beijing Continent Pharmaceuticals Co., Ltd. (d/b/a Gyre Pharmaceuticals Co., Ltd.) ( Gyre Pharmaceuticals ). Overview We are a commercial-stage biopharmaceutical company focused on the development and commercialization of small-molecule therapies for the treatment of organ fibrosis and inflammatory diseases. We operate through our majority indirectly owned subsidiary, Gyre Pharmaceuticals, in the PRC, and through our U.S. operations headquartered in San Diego, California. In the PRC, we have established a strong commercial and operational foundation in fibrotic diseases through the successful development and commercialization of ETUARY (pirfenidone), which has generated consistent revenue and positioned us as a leading participant in the treatment of pulmonary fibrosis. Fibrotic diseases affect large patient populations worldwide and involve complex, multi-stage biological processes driven by multiple molecular pathways. Given this complexity, therapies that modulate key profibrotic signaling pathways may offer meaningful clinical benefit; however, effective treatment may require targeting mechanisms across different stages of disease progression. Building on our commercialization experience and infrastructure in the PRC, we have expanded our presence into the United States to advance the clinical development of our innovative pipeline, including F351 (Hydronidone), our lead product candidate for liver fibrosis.
