Context

• These entries reflect an RSU vesting event and a routine sell-to-cover for tax withholding—not a discretionary open-market sale for investment purposes. The derivative code (M) denotes conversion/exercise of the contingent award into shares; the subsequent sale satisfied required tax withholding. Such sell-to-cover transactions are common after equity awards and do not, by themselves, indicate the insider’s broader market view.
