Context

• This is a routine "sell-to-cover" style tax withholding (reported with code F) when RSUs vest; it reflects tax obligations rather than a discretionary sale and is generally not taken as a directional signal about the insider's view of the stock. Purchases by insiders tend to be more informative for bullish interest.
