Restricted Stock Units financial

"Reflects the conversion of shares of vested Restricted Stock Units granted on June 5, 2025 into shares of Common Stock on a 1:1 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.
