• Transaction type/code: F — Payment of exercise price or tax liability (shares withheld to cover taxes).

Context

• Share withholding to satisfy tax obligations is a routine administrative action (net settlement) and is not the same as an insider selling shares into the market. It reduces the number of shares delivered on vesting but does not necessarily indicate a change in the insider’s investment view.
