Context This was an equity compensation grant (RSUs), a common form of employee pay; it does not reflect an open-market purchase or sale. RSUs convert to actual shares only upon vesting and settlement, so the award increases potential future share holdings rather than current tradable shares. As with most grants, this is part of compensation and not a direct signal of insider buying or selling.
