• Filing appears timely (reported the next day); disposition code F indicates tax withholding rather than an open-market sale.

Context
This was primarily an award/vesting event (acquisition of RSUs/PSUs) rather than an investment purchase or discretionary sell. The 524-share disposition was a routine tax-withholding action common when awards vest—not an open-market sale intended to realize gains. RSUs will vest over future dates, so further withholding or sales may occur at those times.
