Context

• RSUs are awards that convert to shares upon vesting; bonus RSUs that vested immediately generated a tax liability that was covered by the reported open‑market sale. The option grant is a standard multi‑year vesting grant and does not represent immediately tradable shares until vested/exercised.
• Sales to cover tax withholding are routine and do not necessarily signal a change in insider sentiment; purchases by insiders are generally more directly interpreted as bullish signals.
