The decrease was primarily driven by net cash used in operations, offset by the $210.0 million upfront payment received from Servier related to the exclusive license agreement for darovasertib during the year ended December 31, 2025.Collaboration revenue for the three months ended December 31, 2025, totaled $10.9 million compared to $7.0 million for the three months ended December 31, 2024. Collaboration revenue was recognized for the performance obligations satisfied through December 31, 2025 related to the research and development services that are recognized over time under the Servier exclusive license agreement for darovasertib. As of December 31, 2025, the remaining balance for the research and development services performance obligations is $161.8 million related to the clinical trial cost reimbursements anticipated under the license agreement that will be recognized as IDEAYA collaboration revenue over time as the research and development services are completed.Research and development (R&D) expenses for the three months ended December 31, 2025 totaled $86.6 million compared to $140.2 million for the three months ended December 31, 2024. The decrease was primarily driven by a $75.0 million upfront payment under the license agreement for IDE849 with Hengrui Pharma during the three months ended December 31, 2024, offset by higher clinical trial and CMC manufacturing expenses to support our programs and personnel-related expenses during the three months ended December 31, 2025.General and administrative (G&A) expenses for the three months ended December 31, 2025 totaled $18.8 million compared to $11.0 million for the three months ended December 31, 2024.
