Restricted stock units (RSUs) financial

"Restricted stock units (RSUs) vest in full on the first anniversary of the date of the grant."

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.
