Context
This filing reflects an award of restricted stock units and a routine tax-withholding share disposition—not an open-market sale. RSU grants are compensation and vest in the future; the withheld shares were used to cover taxes at vesting/grant-related tax obligation rather than indicating a directional trade by the insider. Transaction codes: A = award/acquisition, F = tax withholding/disposition.
