Context This was a routine, issuer-mandated "sell to cover" for tax withholding on vested RSUs, which means it reflects tax logistics rather than a voluntary decision to reduce exposure. Such mandated sales are common following RSU vesting and are different from discretionary insider selling that might signal a change in sentiment.
