"mandatory “sell-to-cover” provision"

restricted stock units (RSUs) financial

"restricted stock units ("RSUs")"

Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.

"Each RSU represents a contingent right to receive one share"

vesting date financial

"through the applicable vesting date"
