Context
RSU vesting and withholding are routine forms of equity compensation and tax settlement; withholding shares (code F) is effectively a cashless method to cover taxes and is treated as a disposition for reporting purposes. This filing reflects compensation vesting and tax withholding, not an open-market purchase or voluntary sale. Purchases or open-market sales by insiders tend to be more informative for investor sentiment than routine vesting/withholding transactions.
