Context A "sell-to-cover" occurs when an insider sells a portion of newly vested RSU shares to cover required tax withholdings; it is a routine administrative action and not necessarily a signal about the executive's view of the company. The filing is factual and does not indicate discretionary selling beyond meeting tax obligations.
