Context
This was a standard RSU vesting and conversion, not an open-market purchase or sale motivated by trading decisions. The F-code disposal reflects shares withheld to cover tax obligations (a common, routine process often described as a cashless withholding). The net issuance increased the insider's shareholdings by the net retained shares (3,040).
