Restricted stock units financial

"Restricted stock units ("RSUs") convert into common stock on a one-for-one 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.

Annual Meeting of Stockholders regulatory

"vested in full on September 2, 2026, the date of the Issuer's 2026 Annual Meeting of Stockholders"

vesting financial

"RSUs will vest in full on the date of the Issuer's 2027 Annual Meeting of Stockholders"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
