Context
Tax withholding on vested RSUs is a routine administrative transaction that reduces share count to cover taxes and does not necessarily indicate the insider’s view of the company. It differs from an open-market sale (which can signal liquidity or sentiment) and from option-exercise sales — here shares were simply surrendered to the issuer for tax purposes.
