Material Changes vs. Prior Period
- Revenue: For the three months ended June 30, 2025, revenue increased by $0.3 million compared to the prior year, driven by higher reported HCV sales from AbbVie. For the nine-month period, revenue decreased by $2.8 million due to lower HCV sales.
- Net Loss: Net loss improved significantly. The three-month loss decreased by $4.4 million, and the nine-month loss decreased by $24.0 million compared to the prior year periods.
- Operating Expenses: Total operating expenses decreased by $4.9 million (quarterly) and $27.7 million (year-to-date).
- R&D: Decreased by $1.5 million (quarterly) and $17.8 million (YTD), primarily due to the timing of clinical trials in RSV programs and reduced costs in the COVID-19 program.
- G&A: Decreased by $3.4 million (quarterly) and $9.9 million (YTD), largely driven by reduced legal expenses related to the patent infringement suit against Pfizer.
- Cash Flow: Net cash used in operating activities improved dramatically from $68.4 million in the prior nine-month period to $12.8 million in the current period. This improvement was driven by lower R&D payments and the receipt of a $33.8 million federal income tax refund in April 2025.
Outlook, Risks, and Management Commentary
- Liquidity: As of June 30, 2025, the company held $204.1 million in cash, cash equivalents, and short-term marketable securities. Management expects these resources, combined with retained royalty cash flows, to fund operations into fiscal 2028.
- Development Pipeline:
- RSV: Zelicapavir (N-protein inhibitor) completed a pediatric Phase 2 study with positive topline results showing viral load reduction. A Phase 2b study in high-risk adults completed enrollment in May 2025, with data expected in September 2025. EDP-323 (L-protein inhibitor) showed positive results in a Phase 2a challenge study.
- Immunology: The company selected EPS-1421 as the lead KIT inhibitor candidate for Chronic Spontaneous Urticaria (CSU) and is conducting IND-enabling studies. STAT6 inhibitor programs are in preclinical lead optimization.
- Legal Proceedings: The company is appealing a District Court summary judgment ruling that invalidated its '953 Patent in its infringement suit against Pfizer regarding Paxlovid. The appeal is pending before the Federal Circuit.
- Royalty Sale Agreement: The company continues to pay 54.5% of future MAVYRET/MAVIRET royalties to OMERS (capped at 1.42x the $200M purchase price). The liability balance was $147.7 million as of June 30, 2025.
- Tax Legislation: The company is assessing the impact of the "One Big Beautiful Bill Act" (OBBBA) enacted on July 4, 2025, which extends certain provisions of the Tax Cuts and Jobs Act of 2017.
Investor Verification Checklist
- Cash Runway: Verify the sustainability of the $204.1 million cash position against the projected burn rate into fiscal 2028, considering the timing of upcoming clinical data readouts.
- Royalty Dependency: Assess the impact of AbbVie's MAVYRET sales trends on future revenue, noting that 54.5% of royalties are committed to OMERS until 2032.
- Legal Risk: Monitor the status of the appeal against Pfizer regarding the '953 Patent, as a loss could impact potential future revenue streams or licensing opportunities.
- Clinical Milestones: Track the September 2025 topline data release for the Zelicapavir high-risk adult study and the progress of the EPS-1421 IND-enabling studies.
- Expense Management: Confirm if the reduction in R&D and G&A expenses is sustainable or if it reflects a temporary lull in clinical trial activity.
