performance based restricted stock units financial

"Vesting of award of performance based restricted stock units"

Performance-based restricted stock units are a form of employee pay where shares are promised but only delivered if the company meets specific performance targets over time. Like a trophy awarded to a team after hitting certain goals, they align employee incentives with business results and can affect future share counts and earnings—so investors watch them for signals about management’s motivation, potential dilution, and the likelihood of meeting growth or profit targets.
