Restricted Stock Unit financial

"Each restricted stock award ("RSU") represents a contingent right to receive 1 share of the Issuer's Common Stock upon settlement for no consideration."

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
