Avatrombopag: Commercialization of avatrombopag was initiated in March 2025, expanding Gyre’s footprint in hepatology and hematology. Approved for thrombocytopenia in adults with chronic liver disease and immune thrombocytopenic purpura, the launch aligns with Gyre’s strategy to deepen clinical engagement with liver disease specialists and diversify the market of available products.

Indication Expansion: Oncology Supportive Care

Pirfenidone New Indication: In March 2025, Gyre received NMPA approval to initiate a clinical trial of pirfenidone for RILI, including cases complicated by CIP. This development positions pirfenidone for potential entry into oncology supportive care, with plans to begin an adaptive Phase 2/3 trial in the second half of 2025 across top oncology centers in China.

Financial Results

Cash Position

As of March 31, 2025, Gyre Therapeutics held $15.0 million in cash and cash equivalents, $14.8 million in short-term bank deposits, and $21.4 million in long-term certificates of deposit, totaling $51.3 million.

Gyre believes that its existing cash resources, combined with anticipated cash flow from commercial operations, will be sufficient to fund its operating and capital requirements for the next 12 months.

Financial Results for the Three Months Ended March 31, 2025

• Revenues: Revenues for the three months ended March 31, 2025, were $22.1 million, compared to $27.2 million in the same period last year. The $5.1 million decrease was primarily due to a $5.2 million decline in ETUARY^® sales. This was anticipated, as early 2024 revenues were elevated by a one-time marketing campaign focused on rural expansion, which we did not repeat in 2025. The shift in marketing resources was deliberate, with funds reallocated to support the upcoming launches of Nintedanib and avatrombopag. Additionally, weaker economic conditions in China and increased competition in the IPF treatment market also contributed to the decline. Revenues from generic products decreased by $0.2 million, partially offset by $0.3 million in initial revenue from the March 2025 launch of avatrombopag.
  

Gyre anticipates revenue growth over the remainder of the year, driven by the planned commercial launch of Nintedanib in May 2025 and the continued expansion of avatrombopag. Based on current performance and market outlook, the company is reaffirming its full-year 2025 revenue guidance of $118 to $128 million¹, compared to $105.8 million in 2024.

• Cost of Revenues: For the three months ended March 31, 2025, cost of revenues was $0.9 million, compared to $1.0 million for the same period in 2024. The $0.1 million decrease was in line with the corresponding decline in sales.

• Selling & Marketing Expense: For the three months ended March 31, 2025, selling and marketing expense was $10.8 million, compared to $12.5 million for the same period in 2024. The $1.7 million decrease was primarily driven by a reduction in commission costs due to the decrease of sales.

• Research & Development Expense: For the three months ended March 31, 2025, research and development expense was $3.1 million, compared to $2.2 million for the same period in 2024. The increase was primarily attributable to Gyre Pharmaceuticals and was driven by a $1.3 million increase in clinical research expenses, primarily related to data analysis costs for F351. This increase was partially offset by a $0.2 million decrease in materials and utilities and a $0.1 million reduction in staff costs, primarily due to reduction of headcounts. The overall increase was further offset by a $0.1 million decrease from Gyre Therapeutics, due to the reduction in contract services.
  

[1] 2025 revenue guidance assumes a constant foreign currency exchange rate and no significant economic disruption or downturn.

• General & Administrative Expense: For the three months ended March 31, 2025, general and administrative expense was $5.0 million, compared to $3.4 million for the same period in 2024. The increase was primarily driven by a $0.6 million increase in functional and administrative department's personnel and stock compensation costs, a $0.8 million increase in miscellaneous expense, mainly due to the increase in the annual meeting expense.

• Income from operations: For the three months ended March 31, 2025, income from operations was $2.3 million, compared to $8.1 million for the same period in 2024. The decrease was primarily due to a reduction in revenue.

• Net Income: For the three months ended March 31, 2025, net income was $3.7 million, compared to $9.9 million in net income for the same period in 2024. The decrease was primarily attributable to lower income from operations and unfavorable change in fair value of warrant liabilities.

• Non-GAAP Adjusted Net Income: For the three months ended March 31, 2025, non-GAAP adjusted net income was $2.9 million, compared to $8.2 million non-GAAP adjusted net income for the same period in 2024. The decrease was primarily driven by the decline in revenue of $5.1 million and increase in operating expenses of $0.2 million.

Use of Non-GAAP Financial Measures by Gyre Therapeutics, Inc.

Gyre reports financial results in accordance with accounting principles generally accepted in the United States (“GAAP”). This release presents the financial measure “adjusted net income,” which is not calculated in accordance with GAAP. The most directly comparable GAAP measure for this non-GAAP financial measure is “net income.” Adjusted net income presents Gyre’s results of operations after excluding gain from change in fair value of warrants, stock-based compensation, and provision for income taxes. This is meant to supplement, and not substitute, Gyre’s financial information presented in accordance with GAAP. Adjusted net income as defined by Gyre may not be comparable to similar non-GAAP measures presented by other companies. Management believes that presenting adjusted net income provides investors with additional useful information in evaluating the Gyre’s performance and valuation. See the reconciliation of adjusted net income to net income in the section titled “Reconciliation of GAAP to Non-GAAP Financial Measures” below.

About F351 (Hydronidone)

F351 is a structural analogue of the approved anti-fibrotic IPF drug pirfenidone and has been shown to inhibit in vitro both p38γ kinase activity and TGF-β1-induced excessive collagen synthesis in hepatic stellate cells (“HSCs”), which are recognized as critical event in the development and progression of fibrosis in the liver. This is further supported by its anti-proliferative effects on the HSCs in the liver. In vitro anti-fibrotic effects of F351 were also confirmed in several established in vivo models of liver fibrosis such as CCI4-induced liver fibrosis mouse model, DMN-induced liver fibrosis rat model, and HSA-induced liver rat model, as well as mouse model of MASH fibrosis (CCI4+Western High Fat Diet).

About Gyre Pharmaceuticals

Gyre Pharmaceuticals is a commercial-stage biopharmaceutical company committed to the research, development, manufacturing and commercialization of innovative drugs for organ fibrosis. Its flagship product, ETUARY^® (pirfenidone capsule), was the first approved treatment for IPF in the PRC in 2011 and has maintained a prominent market share (2024 net sales of $105.8 million). In addition, Gyre Pharmaceuticals is evaluating F351 in a Phase 3 clinical trial in CHB-associated liver fibrosis in the PRC, which is expected to report topline data by Q2 2025. F351 received Breakthrough Therapy designation by the NMPA Center for Drug Evaluation in March 2021. Gyre Pharmaceuticals is also developing treatments for PD, DKD, RILI with or without immune-related pneumonitis, COPD, PAH and ALF/ACLF. In October 2023, Gyre Therapeutics acquired an indirect majority interest in Gyre Pharmaceuticals (also known as Beijing Continent Pharmaceuticals Co., Ltd.).
