Context

• This was an award vesting event with shares withheld to cover tax obligations (common practice). The filing reflects conversion of equity compensation (derivative to stock) rather than a market buy or voluntary sale. Transaction codes: M = exercise/conversion of derivative (RSU conversion here); F = payment of tax liability via share withholding.
