Performance Share Unit financial
"Each performance share unit represents a contingent right to receive one share of Corning Incorporated common stock."
A performance share unit (PSU) is a form of executive or employee pay that promises shares (or the cash value of shares) only if the company meets specific performance targets over a set period. Think of it like a bonus cheque that only arrives if the company hits agreed goals — it aligns managers’ rewards with business results and signals to investors how leadership is being incentivized to grow value over time.
Restricted Stock Unit financial
"Each restricted stock unit represents a contingent right to receive one share of Corning Incorporated common stock."
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
tax-withholding disposition financial
"Payment of exercise price or tax liability by delivering securities"
A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.
service-based vesting requirement financial
"Earned PSUs remain restricted until April 15, 2027, when they vest and convert to common stock, subject to service-based vesting requirement."
