"grant of restricted share units (RSUs) awarded to the Reporting Person"

Restricted share units (RSUs) are a form of employee pay where a company promises to give shares (or their cash value) to workers after certain conditions, usually time or performance, are met. For investors, RSUs matter because they can increase the number of shares outstanding and signal how management is being paid and incentivized—think of them as delayed bonuses that convert into ownership when vesting conditions are satisfied.
