Executive summary

  • Achieved net income of $16.0 million for Q3 2025, driven by a $20.0 million gain from the sale of interest in REV102 to Recursion Pharmaceuticals.

  • Discontinued the RLYB212 program for FNAIT prevention after Phase 2 PK data failed to meet efficacy targets.

  • Advanced lead program RLYB116, completing dosing in Cohort 1 of the confirmatory PK/PD Phase 1 study, with data expected in Q4 2025.

  • Implemented workforce reductions in 2024 and 2025, reducing headcount by approximately 40% and 45% respectively, contributing to lower operating expenses.

Financial highlights

  • Q3 2025 revenue was $0.2 million, down from $0.3 million in Q3 2024, all from collaboration and license agreements.

  • Operating expenses for Q3 2025 were $7.1 million, a decrease from $12.4 million in Q3 2024, reflecting lower R&D and G&A costs.

excellent app, it gives me free access to company earnings calls and annual reports. I also love the convenience of calls being available offline so I can listen in whilst doing other things and even when internet or WiFi isn't available.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
