Key Financial Metrics
| Metric | 2025 | 2024 |
|---|---|---|
| Total Revenue | $116.6 million | $105.8 million |
| Net Income (Consolidated) | $9.9 million | $17.9 million |
| Net Income Attributable to Common Stockholders | $5.0 million | $12.1 million |
| Diluted EPS | $0.02 | $0.05 |

Revenue Composition (2025): ETUARY® (pirfenidone) accounted for 91.0% ($106.1 million). New products Contiva® (avatrombopag) and Etorel® (nintedanib) contributed 4.7% ($5.5 million) and 4.0% ($4.6 million), respectively.
Material Changes vs. Prior Period
- Revenue Growth: Revenue increased 10.2% year-over-year, driven by the commercial launch of Contiva® and Etorel® in 2025, partially offset by a slight decline in generic drug revenue.
- Profitability Decline: Net income attributable to common stockholders decreased 58.4% to $5.0 million. This was primarily due to a $4.5 million decrease in the gain from the change in fair value of warrant liability and increased operating expenses.
- Expense Increases:
- Selling & Marketing: Increased 13.3% to $65.2 million due to promotional campaigns for new product launches.
- General & Administrative: Increased 29.1% to $20.8 million, largely driven by a $3.3 million increase in stock-based compensation.
- R&D: Increased 13.9% to $13.7 million, reflecting higher clinical trial costs for Hydronidone and other pipeline candidates.
- Liquidity Improvement: Cash and cash equivalents increased significantly from $11.8 million to $37.1 million, bolstered by a $23.0 million public offering of common stock in May 2025.
Guidance, Outlook, and Risks
Management Commentary and Outlook
- Hydronidone (Lead Candidate):
- PRC (CHB-associated liver fibrosis): Met primary endpoint in Phase 3 trial (52.85% fibrosis regression vs. 29.84% placebo). The Company expects to submit a New Drug Application (NDA) for conditional approval in the first half of 2026.
- U.S. (MASH-associated liver fibrosis): Phase 1 completed. The Company intends to file a U.S. IND in 2026 to initiate a Phase 2 clinical trial.
- ETUARY® Expansion: Phase 3 trial for Pneumoconiosis (PD) enrollment completed in 2025. An adaptive Phase 2/3 trial for Radiation-Induced Lung Injury (RILI) is expected to initiate in the first half of 2026.
- Merger with Cullgen: The Company anticipates the merger will expand its pipeline and commercial capabilities, though benefits are contingent on successful closing.
Risks and Contingencies
- Merger Uncertainty: The Cullgen merger is subject to stockholder approval and HSR Act filing. Failure to close could result in significant transaction costs without realizing strategic benefits.
- Regulatory and Clinical Risk: Success depends on regulatory approvals for Hydronidone and ETUARY® label expansions. Clinical trial outcomes are uncertain, and regulatory pathways for MASH are evolving.
- Supply Chain and Geopolitics: The Company relies on third-party manufacturers in the PRC (e.g., WuXi STA). The U.S. BIOSECURE Act (enacted Dec 2025) designates certain Chinese biotech companies as "of concern," potentially restricting future U.S. federal contracts or grants if the Company continues to use these suppliers.
- Customer Concentration: Three customers accounted for approximately 76.6% of total revenue in 2025. The largest customer, Sinopharm Group, accounted for 51.7% of revenue.
- PRC Pricing Pressure: Etorel® was selected in the National Centralized Drug Procurement program in November 2025, which may impact future pricing and margins.
Key Facts for Investor Verification
- Merger Status: Verify the timeline and conditions for the Cullgen Inc. merger, including stockholder approval dates and regulatory clearance.
- Hydronidone NDA Submission: Confirm the submission date of the NDA for CHB-associated liver fibrosis in the PRC and the subsequent regulatory feedback.
- U.S. IND Filing: Monitor the filing and effectiveness of the U.S. IND for Hydronidone in MASH to assess the timeline for Phase 2 initiation.
- Centralized Procurement Impact: Assess the final pricing and volume commitments resulting from Etorel®'s inclusion in the PRC National Centralized Drug Procurement program.
- BIOSECURE Act Compliance: Review the Company's contingency plans for U.S. clinical supply chains in light of the BIOSECURE Act restrictions on Chinese manufacturers.
- Cash Runway: Evaluate the sufficiency of the $37.1 million cash balance to fund operations and the planned Phase 2 MASH trial without further dilution.
