restricted stock units financial

"Represents restricted stock units granted on May 21, 2026, which vest in 12 equal monthly installments"

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.

vesting financial

"which vest in 12 equal monthly installments over one year with a vesting commencing date of May 21, 2026"

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.
