Context

• This was a routine RSU vesting with share withholding to cover taxes (common practice), not an open-market sale or purchase. Transaction codes: M = exercise/conversion of derivative (RSU vesting here), F = payment of tax liability via share withholding. Such withholding transactions generally reflect compensation tax mechanics rather than a change in insider sentiment.
