Restricted stock units financial

"Restricted stock units vest 100% the earlier of the day before the next annual stockholder meeting or 1 year from the date of grant."

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.
