Restricted Stock Units financial

"Each restricted stock unit represents a contingent right to receive one share of S&T Bancorp, Inc. common stock."

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.

Spouse IRA financial
