"vesting of performance-vesting restricted stock units"

Performance-vesting restricted stock units are a form of employee pay where future company shares are granted only if the business meets specific targets, such as revenue, profit, or stock-price goals. Think of them as a bonus you earn only when certain milestones are hit; for investors they matter because they can increase the number of shares outstanding if goals are met and they reveal how management is being motivated to hit particular financial or operational objectives.
