Restricted Stock unit award financial

"Restricted Stock unit award granted pursuant to the Issuer's 2021 Stock Option and Incentive Plan"

A restricted stock unit award is a promise by a company to give an employee a specified number of company shares at a future date if certain conditions are met, such as staying with the company or hitting performance goals. For investors, these awards matter because they can increase the total number of shares outstanding when converted, diluting existing holders, and they align employees’ incentives with shareholders’ interests much like giving a rising bonus that becomes real only after conditions are satisfied.
