Restricted Stock Units financial
"These shares were retained by the Company in order to meet the tax withholding obligations of the award-holder in connection with the vesting of an installment of the restricted stock units."
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 restricted stock unit award granted on August 8, 2022 vests over a four-year period."
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.
