Context
Sell‑to‑cover transactions are a common administrative step when RSUs vest and the holder sells enough shares to cover taxes; they are generally not interpreted as a deliberate market‑timing sale. For retail investors, outright purchases by insiders often carry more signal than routine withholding sales. This filing documents routine tax withholding rather than a discretionary divestiture.
