Context
Tax-withholding on RSU vesting is routine and reflects an administrative disposition of shares to satisfy taxes; it does not necessarily signal insider sentiment about the company. Unlike an open-market sale, withheld shares reduce the insider’s outstanding share count without a market transaction.
