Context This was not an open-market buy or sell for investment purposes but issuance from equity awards (exercise/conversion of derivatives/RSUs) with shares withheld to cover taxes — a routine administrative outcome when restricted stock units or similar awards vest. The filing also references prior and remaining award vesting schedules (including conditional PSUs and future RSU vesting dates).
