Context

• These were RSU vesting events (conversion of derivative awards), not cash purchases. The F-coded disposals represent shares withheld to cover tax withholding obligations; the M-coded entries reflect conversion/settlement of RSUs. The subsequent open-market sales are routine disposition of vested shares and do not by themselves indicate management sentiment. No purchase transactions were reported.
