Context
These actions reflect equity award administration (forfeiture of PRSUs and share withholding for taxes), not an open-market sale or a purchase. For retail investors, withholding/forfeiture events are routine accounting/tax mechanics tied to equity awards and do not necessarily signal insider sentiment about the company.
