Performance Restricted Stock Units financial
"Performance Restricted Stock Units (PRSUs) granted on February 22, 2023"
Performance restricted stock units (PRSUs) are promises to deliver company shares to employees or executives only if the business meets specific performance targets and any time-based holding rules. Think of them as a bonus that converts into stock only after set goals are reached, so investors watch PRSUs for two reasons: they can dilute existing shares if paid out, and they signal how closely management’s pay is tied to company performance.
Restricted Stock Units financial
"Represents the number of shares of Common Stock that have been withheld"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
net settlement financial
"obligations in connection with the net settlement of the Restricted Stock Units"
income tax withholding financial
"withheld by the issuer to satisfy its income tax withholding and remittance"
accelerated vesting financial
"subject to accelerated vesting in specified circumstances"
A contract feature that makes stock awards, options, or restricted shares become owned or exercisable earlier than the original schedule. It shortens or cancels the waiting period so recipients can sell, transfer, or exercise their equity sooner — think of a timed lock that is unlocked ahead of schedule. It matters to investors because it changes when shares enter the market, who controls them, and how much dilution or ownership concentration happens.
