Context These were not open-market purchases but routine dispositions to satisfy tax withholding obligations from equity awards and small fractional-account adjustments. Such tax-withholding sales are common following vesting and do not necessarily indicate management sentiment about the stock. There is no indication here of an option exercise for immediate sale (cashless exercise) or a 10% owner transaction.
