Context

• These are compensation grants (awards), not open-market purchases or sales. RSUs and option grants are commonly used to retain and incentivize executives and do not reflect an immediate buy or sell decision by the insider. Vesting over four years means the economic benefit depends on continued employment and future vesting/exercise events.
