restricted stock units financial

"restricted stock units became fully vested on 5/19/2026, of which 1,961 shares were traded"

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.
