Context RSUs are a form of equity compensation that convert into shares (or cash equivalent) only upon vesting; they do not represent immediate share purchases or sales. For investors, RSU grants can mean future dilution when/if they convert to common stock; they are routine director compensation and do not by themselves signal a buy or sell decision.
