• Achieved statistically significant ≥1-stage fibrosis regression at Week 52 vs. placebo (52.85% vs. 29.84%, P=0.0002).
• Demonstrated favorable safety and tolerability profile: 4.88% serious adverse events vs. 6.45% for placebo; zero discontinuations due to adverse events.
• Breakthrough Therapy Designation granted by China’s National Medical Products Administration (“NMPA”) in 2021 supports potential first-in-class approval in CHB-associated liver fibrosis (“CHB fibrosis”).
• Gyre intends to seek accelerated approval for Hydronidone in CHB fibrosis, with a New Drug Application (“NDA”) submission to the NMPA expected in Q3 2025.
• U.S. Phase 2 trial in MASH-associated liver fibrosis expected to begin in 2H2025.

SAN DIEGO, May 22, 2025 (GLOBE NEWSWIRE) — Gyre Therapeutics (“Gyre”) (Nasdaq: GYRE), an innovative, commercial-stage biotechnology company focused on organ fibrosis, today announced that its lead compound, Hydronidone (F351), met the primary endpoint in a pivotal Phase 3 trial evaluating its efficacy and safety for the treatment of liver fibrosis in patients with chronic hepatitis B (“CHB”) in China.

The 52-week, multicenter, double-blind, placebo-controlled trial enrolled 248 patients with CHB fibrosis across 39 hospitals in China. Patients were randomized 1:1 to receive either Hydronidone (270 mg/day, orally) or placebo, in addition to background entecavir antiviral therapy. The trial met its primary endpoint, with a statistically significant proportion of patients receiving Hydronidone achieving a ≥1-stage regression in liver fibrosis compared to placebo (P=0.0002). These results are consistent with the efficacy and safety outcomes observed in Gyre’s prior Phase 2 trial.

“These landmark Phase 3 results represent a major step forward for Gyre and for the millions of Chinese patients living with CHB fibrosis,” said Han Ying, Ph.D., CEO of Gyre Therapeutics. “Pending regulatory approval in China, Hydronidone may become the first therapy specifically indicated for reversing liver fibrosis in CHB patients and the foundation for broader expansion into metabolic dysfunction-associated steatohepatitis (“MASH”)-related fibrosis in the United States. We are deeply grateful to the patients and investigators who participated in this pivotal trial and made this important milestone possible.”

“The fibrosis regression in our trial marks a breakthrough in the treatment of CHB fibrosis,” said Prof. Lungen Lu, M.D., Dean of the Department of Gastroenterology at Shanghai General Hospital, Shanghai Jiaotong University School of Medicine, and lead principal investigator. “With no approved anti-fibrotic therapies for this liver disease currently available, Hydronidone has the potential to transform the treatment landscape and offer new hope to patients facing the serious risks of cirrhosis, liver failure, and hepatocellular carcinoma.”

Hydronidone Week 52 Results

The efficacy analysis followed the intent-to-treat (“ITT”) principle. The ITT population comprised all randomized subjects who received at least one dose of study drug. One randomized subject who did not receive any treatment was excluded. All biopsies were independently reviewed by three blinded central pathologists to ensure consistency and objectivity of fibrosis and inflammation assessments.

Efficacy Results

In the ITT population, Hydronidone demonstrated statistically significant regression in liver fibrosis compared to placebo.

Primary Endpoint	Hydronidone 270mg N=123		Placebo N=124		P-value
≥1-stage fibrosis regression (Ishak)	52.85%		29.84%		P=0.0002
Key Secondary Endpoints
≥1-Grade inflammation improvement (Scheuer score) without progression of fibrosis	49.57%		34.82%		P=0.0246

Safety Results

Hydronidone was well tolerated, with a comparable incidence of serious adverse events (4.88% vs. 6.45% in the placebo group) and no discontinuations due to adverse events in either group. Most adverse events were mild or moderate and unrelated to Hydronidone, while a small number of severe adverse events occurred, none of which were considered related to the trial drug.

Our Path Forward

Gyre plans to submit primary results for publication in a peer-reviewed journal and present full trial results at a future medical congress.

Based on these positive results, Gyre plans to file an NDA with China’s NMPA in the third quarter of 2025. In parallel, the Company is actively preparing to file an investigational new drug (“IND”) application in the third quarter of 2025 and, subject to IND clearance, plans to initiate a Phase 2 trial in the U.S. evaluating Hydronidone for the treatment of MASH-associated fibrosis in the second half of 2025. A prior U.S. Phase 1 trial in healthy volunteers confirmed Hydronidone’s tolerability and demonstrated a pharmacokinetic profile consistent with the Chinese population.

About the Phase 3 Trial

The randomized, double-blind, placebo-controlled multicenter Phase 3 trial (NCT05115942) enrolled 248 patients with CHB fibrosis (Ishak fibrosis stage ≥3) across 39 hospitals in China. Patients were randomized 1:1 to receive either 270 mg Hydronidone or placebo daily, in combination with entecavir. The primary endpoint of the trial was the efficacy of fibrosis regression, defined as a decrease in the Ishak stage score of liver fibrosis ≥ 1 after 52 weeks of treatment compared to baseline. A key secondary endpoint was a ≥1-grade reduction in liver inflammation, as assessed by the Scheuer scoring system, after 52 weeks of treatment compared to baseline, without progression of fibrosis.

Patient Population for CHB-Associated Liver Fibrosis

According to national serological surveys, approximately 75 million people in China are chronically infected with hepatitis B virus. A significant subset develops CHB with progressive fibrosis. Based on internal modeling of epidemiologic and staging data, Gyre estimates that approximately 2.6 million patients in China have been diagnosed with compensated F2-F4 CHB fibrosis, representing the initial addressable market for Hydronidone. CHB remains the leading cause of liver fibrosis in China, and currently no approved anti-fibrotic therapies exist for this population.

Hydronidone is uniquely positioned to address this significant and urgent unmet medical need. Gyre was granted Breakthrough Therapy Designation in 2021 by the NMPA.

About Hydronidone (F351)

Hydronidone (F351) is a structural analogue of Pirfenidone, for which Gyre received first-in-class approval in China in 2011 for the treatment of idiopathic pulmonary fibrosis (IPF). Hydronidone exhibits enhanced potency in inhibiting p38γ kinase activity and TGF-β1-induced collagen synthesis in hepatic stellate cells (HSCs), key drivers of liver fibrosis. It also demonstrates anti-proliferative activity in HSCs through upregulation of Smad7, which downregulates TGF-βRI, thereby suppressing both the p38γ and Smad2/3 fibrogenic pathways.

Hydronidone has shown robust anti-fibrotic activity in multiple preclinical models, including the CCl₄-induced mouse model, DMN- and HSA-induced rat models, and a MASH model combining CCl₄ with a Western high-fat diet. In a randomized, double-blind, placebo-controlled Phase 3 trial, Hydronidone 270 mg/day significantly reduced liver fibrosis in CHB patients after 52 weeks of treatment. Compared to Pirfenidone, Hydronidone’s unique Phase II conjugation metabolism may contribute to an improved hepatic safety profile.

About Gyre Therapeutics

Gyre Therapeutics is a biopharmaceutical company headquartered in San Diego, CA, primarily focused on the development and commercialization of Hydronidone for liver fibrosis including MASH in the U.S. Gyre’s strategy builds on its experience in mechanistic studies using MASH rodent models and clinical studies in CHB-induced liver fibrosis.

SAN DIEGO, May 09, 2025 (GLOBE NEWSWIRE) — Gyre Therapeutics (“Gyre”) (Nasdaq: GYRE), an innovative, commercial-stage biotechnology company focused on organ fibrosis, today announced financial results for the first quarter ended March 31, 2025 and provided a business update.

“This quarter marked a meaningful step forward in expanding our market presence, particularly in the liver space,” said Han Ying, Ph.D., CEO of Gyre Therapeutics. “The successful launch of avatrombopag and our growing commercial footprint with hepatology and hematology specialists provide a strong foundation for our future growth. In addition, the recent NMPA approval to initiate a clinical trial of pirfenidone in radiation-induced lung injury, including with or without immune-related pneumonitis, supports our ability to enter the oncology supportive care space with a novel, lung-protective therapy. We plan to initiate an adaptive Phase 2/3 trial in the second half of 2025 to advance this program through development.”

First Quarter 2025 Business Highlights and Upcoming Milestones

Commercial Portfolio Expansion

ETUARY^® (pirfenidone): Delivered $21.7 million in Q1 sales. While sales declined year-over-year due to relatively high sales in the first quarter of 2024, ETUARY remains the market leader for idiopathic pulmonary fibrosis (IPF) in the PRC.

Nintedanib: Gyre remains on track to commercially launch nintedanib in May 2025, targeting multiple forms of fibrosing interstitial lung disease (“ILD”), including IPF, systemic sclerosis-associated ILD, and progressive fibrosing ILD. This is expected to expand Gyre’s share of the pulmonary fibrosis treatment landscape and support second-half 2025 revenue growth.

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.

Pipeline Development Updates

F573:

• F573 is a caspase inhibitor and potential Category 1 new drug for the treatment of acute/acute on-chronic liver failure (“ALF/ACLF”). Completion of the Phase 2 clinical trial of F573 for ALF/ACLF is expected by the end of 2026.

F230:

• F230, a selective endothelin receptor agonist for the treatment of pulmonary arterial hypertension (“PAH”), is expected to begin a Phase 1 trial in Q2 2025.

F528:

• F528, a novel anti-inflammation agent with the potential to modify the progression of chronic obstructive pulmonary disease (“COPD”), is undergoing preclinical studies as a potential first-line therapy for the treatment of COPD. Gyre Pharmaceuticals plans to submit an IND application in 2026.

Corporate Updates

• In March 2025, Gyre appointed Ping Zhang as Executive Chairman of the Company’s Board of Directors; he remains a member of the Nominating and Corporate Governance Committee.

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.).

About Gyre Therapeutics

Research News and Market Data on GYRE

March 31, 2025

SAN DIEGO, March 31, 2025 (GLOBE NEWSWIRE) — Gyre Therapeutics (“Gyre”) (Nasdaq: GYRE), an innovative, commercial-stage biotechnology company focused on organ fibrosis, today announced that the National Medical Products Administration (NMPA) of the People’s Republic of China (“PRC”) has approved its clinical trial application for a potential new indication for pirfenidone in oncology-related pulmonary complications. The trial will evaluate pirfenidone capsules for the treatment of radiation-induced lung injury (RILI), with or without immune-related pneumonitis (CIP).

This regulatory milestone marks the expansion of pirfenidone beyond its established role in idiopathic pulmonary fibrosis (IPF) into the oncology supportive care space, offering a novel lung-protective strategy for cancer patients undergoing radiation therapy or immunotherapy.

In accordance with the NMPA approval, Gyre intends to pursue an adaptive Phase 2/3 clinical trial design, combining dose exploration with efficacy confirmation, to efficiently evaluate pirfenidone’s potential in this new indication.

Radiation-Induced Lung Injury (RILI): Radiation therapy is a cornerstone of lung cancer treatment. However, 5%–25% of patients experience lung damage due to radiation exposure, limiting the ability to escalate doses and thereby compromising treatment efficacy.

Checkpoint Inhibitor Pneumonitis (CIP): Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment, but 13%–19% of patients develop CIP. This condition accounts for approximately 35% of immune-related adverse event (irAE) deaths and often necessitates treatment discontinuation.

Currently, no targeted therapies exist for lung injuries caused by radiation or immunotherapy. Distinguishing between RILI and CIP is challenging, particularly when both occur concurrently. Corticosteroids remain the standard of care despite significant long-term side effects. By targeting and inhibiting fibrotic pathways, pirfenidone may address the root cause of lung injury progression, offering a new treatment option for patients receiving radiation or immunotherapy.

Gyre anticipates initiating the trial in the second half of 2025 at leading academic and oncology centers across the PRC.

About Pirfenidone
Pirfenidone is an orally administered small molecule approved for the treatment of IPF. It works by inhibiting TGF-β signaling and fibroblast proliferation. The drug has demonstrated clinical benefit in slowing lung function decline in IPF and is now being evaluated for oncology-related pulmonary complications. Gyre has held first-in-class status for pirfenidone in the PRC since its original approval in 2011, underscoring its pioneering role in treating fibrotic lung diseases.

About Gyre Therapeutics
Gyre Therapeutics is a biopharmaceutical company headquartered in San Diego, CA, primarily focused on the development and commercialization of F351 (Hydronidone) for MASH-associated fibrosis in the U.S. Gyre’s strategy builds on its experience in mechanistic studies using MASH rodent models and clinical studies in CHB-induced liver fibrosis. In the PRC, Gyre is advancing a broad pipeline through its indirect controlling interest in Gyre Pharmaceuticals, including therapeutic expansions of ETUARY, and development programs for F573, F528, and F230.

Financial Results

Cash Position

As of December 31, 2024, Gyre had cash, cash equivalents, short-term and long-term bank deposits of $51.2 million.

Financial Results for the Three Months Ended December 31, 2024

• Revenues: Revenues for the three months ended December 31, 2024 were $27.9 million, compared to $27.1 million for the same period in 2023. The $0.8 million increase was primarily driven by a $1.0 million increase in ETUARY’s revenue and a $0.2 million decrease in generic drug revenue. The growth in ETUARY sales was attributed to the active expansion of the IPF treatment market, increased market penetration, and a stronger focus on ETUARY sales. To support future revenue growth, Gyre Pharmaceuticals plans to commercially launch two new products, nintedanib and avatrombopag, in 2025, which will be supported by its extensive sales and marketing platform in the PRC.
• Cost of Revenues: For the three months ended December 31, 2024, cost of revenues was $1.2 million, compared to $1.3 million for the same period in 2023. The $0.1 million decrease was primarily driven by a $0.2 million decrease in generic drug cost due to the decrease in sales and a $0.1 million decrease in factory stoppage loss due to factory renovation in 2023, offset by a $0.2 million increase due to the increase of ETUARY’s cost due to the increase in sales.
• Selling and Marketing Expense: For the three months ended December 31, 2024, selling and marketing expense was $16.9 million, compared to $16.5 million for the same period in 2023. The increase was primarily driven by a $2.1 million increase in promotion expense and conference expenses, offset by a $1.1 million decrease in selling and marketing payroll costs, a $0.3 million decrease in stock-based compensation expense and a $0.3 million decrease in travel and miscellaneous expenses.
• Research and Development Expense: For the three months ended December 31, 2024, research and development expense was $3.7 million, compared to $4.6 million for the same period in 2023. The decrease was primarily driven by a $0.5 million decrease in pre-clinical and clinical research expenses and a $0.5 million decrease in stock-based compensation expense, offset by a $0.1 million increase in miscellaneous expense.
• General and Administrative Expense: For the three months ended December 31, 2024, general and administrative expense was $5.5 million, compared to $10.1 million for the same period in 2023. The decrease was primarily driven by a $5.8 million decrease in stock-based compensation cost, offset by a $0.8 million increase in the functional and administrative department’s personnel cost and a $0.4 million increase in professional expense, including legal and consulting fees.
• Income (Loss) from Operations: For the three months ended December 31, 2024, income from operations was $0.7 million, compared to $91.1 million loss from operation for the same period in 2023. The increase in income from operations was driven primarily by acquired in-process research and development expense recognized in the fourth quarter of 2023 and there was no such expense in the same period in 2024.
• Net Income (Loss): For the three months ended December 31, 2024, net income was $0.6 million, compared to $101.0 million net loss for the same period in 2023.
• Non-GAAP Adjusted Net Income: For the three months ended December 31, 2024, non-GAAP adjusted net income was $1.1 million, compared to $2.1 million for the same period in 2023. The decrease was primarily driven by the costs of being a public company for three months in 2024, as compared to two months in 2023.

Financial Results for the Full Year Ended December 31, 2024

• Revenues: Revenues for the full year ended December 31, 2024 were $ 105.8 million, compared to $113.5 million for the same period in 2023. The $7.7 million decrease was primarily driven by a $7.1 million decrease in ETUARY’s revenue and a $0.6 million decrease in generic drug revenue as a result of decreased sales volumes. The decrease in ETUARY and generic drug sales volumes was due to fluctuations in the Chinese economy that significantly affected demand for anti-fibrosis drugs and decreasing healthcare spending generally. To support future revenue growth, Gyre plans to commercially launch two new products, nintedanib and avatrombopag, in 2025, which will be supported by Gyre Pharmaceuticals’ extensive sales and marketing platform across the PRC.
• Cost of Revenues: For the full year ended December 31, 2024, cost of revenues was $3.9 million, compared to $4.6 million for the same period in 2023. The $0.7 million decrease was primarily driven by a $0.5 million factory stoppage loss due to factory renovation in 2023, which did not occur in 2024, and a $0.2 million decrease due to decreased sales volumes.
• Selling and Marketing Expense: For the full year ended December 31, 2024, selling and marketing expense was $57.5 million, compared to $61.2 million for the same period in 2023. The decrease was primarily driven by a $2.4 million decrease in conference costs and promotion expense due to decreased sales activities, a $0.9 million decrease in selling and marketing payroll costs due to the decrease of sales of ETUARY in 2024, a $0.3 million decrease in share base compensation expense, and a $0.1 million decrease in miscellaneous expenses.
• Research and Development Expense: For the full year ended December 31, 2024, research and development expense was $12.0 million, compared to $13.8 million for the same period in 2023. The decrease was primarily from Gyre Pharmaceuticals, and was driven by a $0.3 million decrease in materials and utilities, a $1.3 million decrease in pre-clinical research expense due to several research and development projects advancing to the clinical trials stage or reaching the application phase in 2024, and a $0.4 million decrease in staff cost due to reduced headcount, and a $0.5 million decrease in stock-based compensation, related to options being fully vested in 2023, which did not occur in 2024, This overall decrease was partially offset by a 0.7 million increase in general research and development expense from Gyre Therapeutics due to increased consulting fees.
• General and Administrative Expense: For the full year ended December 31, 2024, general and administrative expense was $16.1 million, compared to $14.7 million for the same period in 2023. The increase was primarily driven by costs associated with being a public company, including a $1.9 million increase in professional expense, a $2.1 million increase in miscellaneous expenses and a $3.0 million increase in the functional and administrative department’s personnel cost, offset by a $5.6 million decrease in stock-based compensation cost.
• Income (loss) from Operations: For the full year ended December 31, 2024, income from operations was $16.2 million, compared to $67.2 million loss for the same period in 2023. The increase in income from operations was driven primarily by acquired in-process research and development expense recognized in 2023 and there was no such expense in the same period in 2024.
• Net Income (loss): For the full year ended December 31, 2024, net income was $17.9 million, compared to $85.5 million net loss for the same period in 2023.
• Non-GAAP Adjusted Net Income: For the full year ended December 31, 2024, non-GAAP adjusted net income was $16.9 million, compared to $25.4 million for the same period in 2023. The decrease was primarily driven by a $7.7 million decline in revenue and a $1.1 million increase in operating expenses. Despite these changes, the gross profit margin remained consistent.

Full Year 2025 Financial Guidance

For the full year 2025, the Company expects to generate revenues of $118 to $128 million, representing growth of 11.3% to 20.8% over 2024 revenue, primarily driven by the anticipated commercial launches of nintedanib and avatrombopag and sales of ETUARY.

Total Revenue	$118 to $128 million

Please note the following regarding the total revenue guidance:

• Guidance assumes a constant foreign currency exchange rate.
• Guidance assumes no significant economic disruption or downturn.

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 Hydronidone (F351)

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 $105.0 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 readout 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, 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.).

About Gyre Therapeutics

Gyre Therapeutics is a biopharmaceutical company headquartered in San Diego, CA, with a primary focus on the development and commercialization of F351 (Hydronidone) for the treatment of MASH-associated fibrosis in the U.S. Gyre’s development strategy for F351 in MASH is based on the company’s experience in MASH rodent model mechanistic studies and CHB-induced liver fibrosis clinical studies. Gyre is also advancing a diverse pipeline in the PRC through its indirect controlling interest in Gyre Pharmaceuticals, including ETUARY therapeutic expansions, F573, F528, and F230.
