restricted stock units financial

"An annual award of restricted stock units granted pursuant to the company's 2025 Equity Incentive Plan"

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.
