"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.

performance-based restricted stock units financial

"Acquired upon achievement of certain performance criteria pursuant to the performance-based restricted stock units granted April 1, 2022, under the Issuer's 2022 Long Term Incentive Plan."
