Material Changes vs. Prior Period
- Revenue Decline: Total revenue decreased 6% year-over-year. Net product revenue fell 10% to $95.6 million, primarily driven by a 39% drop in ZEJULA sales (due to volume-based procurement for generic olaparib) and a 3% decline in VYVGART (due to NRDL pricing adjustments). These were partially offset by a 667% surge in XACDURO sales and an 8% increase in NUZYRA.
- Collaboration Revenue: Increased significantly by 384% to $4.1 million, attributed to a regional license and collaboration arrangement.
- Expense Growth: R&D expenses rose 8% to $65.6 million, driven by a 99% increase in CRO/CMO/investigator expenses and higher licensing fees. SG&A expenses increased 3% to $65.1 million.
- Foreign Currency Impact: The company recorded a $14.8 million foreign currency gain in Q1 2026 compared to $0.7 million in Q1 2025, largely due to RMB appreciation against the U.S. dollar.
- Cash Flow Improvement: Net cash used in operating activities improved significantly to $11.9 million from $61.7 million in the prior year, aided by favorable changes in operating assets and liabilities.
Guidance, Outlook, and Risks
- Pipeline Progress:
