Note: Q2 2025 net loss was effectively zero due to a $143 million revenue catch-up adjustment from a contract modification with Gilead.
Material Changes vs. Prior Period
- Revenue Decline: Total revenues decreased 74% in Q2 2026 compared to Q2 2025. This is primarily due to the absence of the $143 million cumulative catch-up revenue recognized in Q2 2025 following Gilead's termination of rights to the etrumadenant program. Current revenue is driven by access rights expirations and Taiho collaboration milestones.
- Increased Net Loss: The company reported a net loss of $91 million in Q2 2026, compared to break-even in Q2 2025. The loss widened due to the drop in revenue and continued operating expenses.
- Expense Reduction: Operating expenses decreased 18% year-over-year in Q2 2026. Research and Development (R&D) expenses fell 19% to $113 million, driven by the wind-down of Phase 3 studies for domvanalimab (STAR-121 and PACIFIC-8) and reduced partnership reimbursements.
- Liquidity Position: Cash, cash equivalents, and marketable securities decreased from $1.01 billion at year-end 2025 to $775 million as of June 30, 2026, reflecting operating cash burn and investment activity.
Guidance, Outlook, and Risks
- Liquidity Outlook: Management believes current cash and investments ($775 million) are sufficient to fund operations until at least the second half of 2028. The company has a $250 million term loan facility with Hercules Capital, of which $100 million has been drawn; an additional $150 million is available subject to clinical and regulatory milestones.
- Strategic Shifts:
- Gilead Collaboration: Gilead's option rights to new pipeline programs expired on July 14, 2026, following a decision not to make the sixth-anniversary continuation payment. Gilead retains time-limited options on specific programs (AXL, CD39, TNF).
- Program Discontinuations: The company discontinued the Phase 3 STAR-121 and PACIFIC-8 studies for domvanalimab due to futility in April and August 2026, respectively.
- New Partnerships: Announced collaborations with Bristol Myers Squibb, Summit Therapeutics, and AVEO Oncology to evaluate casdatifan (HIF-2α inhibitor) in renal cell carcinoma.
- Risks: Key risks include the need for additional capital, reliance on third-party manufacturers (including WuXi Biologics in China), potential regulatory delays, and the speculative nature of clinical-stage development. The company faces covenants under its Hercules debt agreement that could restrict operations in an event of default.
Investor Verification Checklist
- Cash Runway: Verify the sufficiency of the $775 million cash balance against the projected burn rate, considering the wind-down of Gilead-funded programs and increased self-funding of casdatifan.
- Debt Covenants: Review the specific financial covenants in the Hercules Capital agreement, particularly the minimum cash requirements beginning July 2027.
- Casdatifan Progress: Monitor enrollment and data readouts for the new casdatifan collaborations (ROSETTA RCC-208, ARC-20) as this is now the primary late-stage asset.
- Manufacturing Supply Chain: Assess risks related to the U.S. BIOSECURE Act and potential restrictions on WuXi Biologics, the sole manufacturer of zimberelimab.
- Revenue Recognition: Understand the timing of future revenue from Taiho milestones and the expiration of Gilead access rights, as these are non-recurring or lumpy events.
