Context RSU awards are a form of compensation and typically vest over time; they are not the same as an open-market purchase (which some investors view as a direct bullish personal investment). Vesting schedules, like the three-year annual vesting here, mean the economic benefit to the insider is realized over future periods rather than immediately.
