Restricted Stock Units financial
"Vesting of restricted stock units ("RSUs") granted to the Reporting Person"
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
"The RSUs will vest in substantially equal increments on each of September 30, 2025, December 31, 2025, March 31, 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.
