Context

• These were vesting PSUs converting to common stock (not an open-market buy or motivated sale). The withholding of shares to cover taxes is a routine, non-sale disposition used to meet tax obligations (a cashless tax withholding). This is standard compensation-related insider activity and does not, by itself, indicate purchase-driven bullishness or a market sale signal.
