Restricted stock units financial

"Restricted stock units ("RSUs") convert into common stock on a one-for-one basis"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
