Context
These entries are awards/conversions tied to the company’s April 9, 2026 merger (not open-market buys or sales). Derivative entries reflect converted/exchanged options rather than exercised-for-cash sales; vesting terms vary by grant. The filing date is later than the usual 2-business-day Form 4 deadline, which the company reported with this filing.
