Context This was a routine RSU vesting/conversion with a portion of shares withheld to satisfy tax obligations (a common practice), not an open-market sale or purchase. The "M" entries reflect conversion/settlement of derivative awards (RSUs); the "F" entry records tax-withholding via share retention. Such vesting and withholding are administrative and do not by themselves indicate insider buying or selling intent.
