restricted stock units financial

"vesting and conversion to shares of 385 restricted stock units ("RSUs") granted on May 1, 2025"

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.
