restricted stock financial

"Shares automatically and mandatorily withheld to satisfy the tax withholding requirement upon the vesting of restricted stock."

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.
