    In connection with Mr. Apel’s appointment as Chief Financial Officer, Mr. Apel will receive an annual base salary of $575,00 and is eligible to receive an annual bonus with a target bonus set at 45% of his base salary for the applicable bonus period.

    Why Late-Stage CNS, Oncology Assets Are Becoming the Hottest Targets in Biotech M&A

    AUSTIN, Texas, Feb. 17, 2026 (GLOBE NEWSWIRE) -- BioMedWire Editorial Coverage: Biotech dealmaking is increasingly defined by a clear strategic shift: Pharmaceutical companies are prioritizing de-risked, late-stage assets with human clinical validation rather than speculative early-stage programs.
