  Sales of Contiva^® and Etorel^®, which commenced commercialization in March 2025 and June 2025, respectively, were primarily driven by the targeted allocation of commercial and marketing resources to support their respective launches during the first half of 2025. The increase in ETUARY^® sales reflects a strategic realignment of marketing efforts in the third quarter of 2025 to optimize product mix and address evolving market dynamics.

• Cost of Revenues: For the full year ended December 31, 2025, cost of revenues was $5.4 million, compared to $3.9 million for the same period in 2024. The $1.5 million increase was primarily driven by a $0.8 million increase in ETUARY^®'s cost, due to higher plant, property and equipment depreciation from a plant renovation completed in the second half of 2024, a $0.6 million increase in the cost of Contiva^® and Etorel^®, in line with the corresponding increase in their sales, and a $0.5 million increase in stock-based compensation expense. These factors were partially offset by a $0.4 million decrease in costs related to generic drugs due to the decrease in sales.
• Selling and Marketing Expense: For the full year ended December 31, 2025, selling and marketing expense was $65.2 million, compared to $57.5 million for the same period in 2024. This $7.7 million increase was primarily driven by a $2.5 million increase in conference expenses and promotional expenses, attributable to the launch of additional promotional campaigns in the current year—particularly for the Company’s new products, a $2.6 million increase in staff costs, which was driven by expanded headcount and higher sales commissions, consistent with the corresponding growth in revenue, a $2.3 million increase in stock-based compensation expense and a $0.3 million increase in traveling and other expense.
• Research and Development Expense: For the full year ended December 31, 2025, research and development expense was $13.7 million, compared to $12.0 million for the same period in 2024. The $1.7 million increase was attributable to a $1.0 million increase in clinical trial costs, primarily as a result of data analysis costs for Hydronidone, PD and RILI, a $0.4 million increase in staff costs, which included $0.2 million in stock-based compensation expense, a $0.5 million increase in facilities, depreciation and other expenses, attributable mainly to professional and consulting fees incurred in connection with research and development operations, and a $0.4 million increase in pre-clinical research expenses. These expense increases were partially offset by a $0.6 million decrease in materials and utilities expenses.
• General and Administrative Expense: For the full year ended December 31, 2025, general and administrative expense was $20.8 million, compared to $16.1 million for the same period in 2024. This $4.7 million increase was primarily driven by a $3.3 million increase in stock-based compensation expense, a $1.3 million increase in functional and administrative department's personnel expense, and a $0.9 million increase in miscellaneous expense. These cost increases were partially offset by a $0.8 million decrease in professional service expenses.
• Income from Operations: For the full year ended December 31, 2025, income from operations was $11.5 million, compared to $16.2 million in income for the same period in 2024. The $4.7 million decrease in income from operations was driven primarily by a $15.5 million increase in total operating expenses, partially offset by a $10.8 million increase in revenue.
• Net Income: For the full year ended December 31, 2025, net income was $9.9 million, compared to $17.9 million net income for the same period in 2024. This $8.0 million decrease was driven primarily by the increase in operating expenses of $15.5 million and decrease in change in fair value of warrant liability of $4.5 million, partially offset by an increase in revenue of $10.8 million, an increase in other income of $0.4 million, and a decrease in income tax expense of $0.8 million.
• Non-GAAP Adjusted Net Income: For the full year ended December 31, 2025, non-GAAP adjusted net income was $18.9 million, compared to $16.9 million for the same period in 2024.

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 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 Hydronidone

Hydronidone is a novel, orally administered anti-fibrotic agent designed to target key liver fibrosis pathways. It attenuates hepatic stellate cell activation and fibrogenesis, at least in part, by suppressing Tumor Growth Transforming (TGF)-β1-induced signal transduction, including reduced p38γ phosphorylation and upregulated Smad7 expression. This upregulation of Smad7 subsequently leads to downregulation of TGF-βRI and inhibition of Smad2/3 activation, thereby disrupting canonical TGF-β/Smad signaling and reducing fibrotic gene expression in hepatic stellate cells.

The drug has completed Phase 3 clinical evaluation in China for chronic hepatitis B (CHB)-associated liver fibrosis, including early (compensated) cirrhosis, and is being evaluated for its potential applicability across additional fibrotic diseases in region-specific development programs.
