On March 10, 2026, a representative of Gyre Therapeutics, Inc. (the "Company") presented the following information at an investor conference:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Based upon patient population data, the Company believes there is the potential for ~$400-600 million in revenues within 5 years
 for liver fibrosis with Hydronidone ("F351").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. The Company expects ETUARY® for lung fibrosis to sustain at ~$100 million if no competitor markets a generic drug in the
 near-term.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. The Company sees the potential for 20% - 25% net margins for commercial products and, provided that no tax policy changes occur,
 favorable tax deductibility on research and development ("R&D") expenditures in the Company's Beijing campus and Cullgen Inc.'s ("Cullgen") Shanghai campus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. The Company believes there is upside potential for F351 with respect to (a) the potential off-label Metabolic
 Dysfunction-Associated Steatohepatitis ("MASH") use by hepatologists upon Chronic Hepatitis B / fibrosis approval with data showing ~40% MASH mix in Hepatitis B Virus practices, and (b) the potential for continued expansion
 through rheumatology disease with lung fibrosis label.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. 30-40% of the Company's current lung fibrosis revenue is derived from rheumatoid diseases (RA, lupus, Scleroderma,
 dermatomyositis) as these patients manifest lung fibrosis as a downstream complication. The Company expects this mix to sustain or grow, consistent with how the drug has penetrated the rheumatoid channel organically.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. Cullgen's Australian cohort validated safety at 400mg (one-third of the maximum tolerated dose) for Cullgen's TRK degrader
 ("CG001419"). Cullgen's United States Phase 2 pain trial for CG001419 is now enrolling at doses expected to show ~95% TRK degradation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. The Company framed the short-course dosing of CG001419 as explicit engineering around NGF-class joint toxicity, where the
 durable pathway blockade was a potential liability for NGF inhibitors as compared to the TRK suppression of CG001419.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. Cullgen has seen the potency of its degrader antibody conjugates ("DAC") to be ~10 - 100 times versus a standalone degrader,
 observed by in vitro and in animal models.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. Approximately one-half of Cullgen's R&D headcount is currently allocated to DAC conjugation. Cullgen expects its degrader
 library depth (picomolar DC50 compounds in hand across multiple targets including GSPT-1) to position it to conjugate without external licensing.
