Restricted Stock Units financial

"The restricted stock units ("RSUs") were settled in shares of common stock"

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

"Withholding of shares to satisfy tax liability on the vesting of RSUs."

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.

withholding of shares financial

"Withholding of shares to satisfy tax liability on the vesting of RSUs."

contingent right financial

"Each RSU represents a contingent right to receive one share"
