Context

• This was an equity grant (compensation award), not an open-market purchase or sale. RSUs are a form of deferred equity: they do not represent tradable shares until vested and settled, so they are not an immediate market vote of confidence or sale. Such grants are common for executive compensation and align retention incentives over the vesting period.
