To own IDEAYA today, you have to believe in its targeted oncology pipeline eventually converting into meaningful, durable revenue, despite the company remaining unprofitable and funding itself through equity. The big near term catalyst is still the darovasertib plus crizotinib program, with an NDA targeted for the second half of 2026 and review under the FDA’s RTOR framework, alongside early but expanding data across IDE397, IDE892 and IDE161.
