Context
Forfeiting or withholding vested RSU shares to cover taxes is routine and administrative — the company retains shares to satisfy withholding obligations rather than the insider selling shares on the open market. These transactions generally do not signal an insider’s decision to buy or sell stock for investment reasons.
