Context
A direct purchase by a CEO increases their outright stake and is often viewed by investors as a positive signal, though it does not prove future performance. The footnotes reference separate restricted-stock grants with multi-year vesting schedules; those are existing/vesting awards and not the open-market purchase itself.
