Deferred Performance Stock Units financial
"Represents deferred stock units acquired upon the reporting person's election to defer"
restricted stock unit financial
"These shares represent a restricted stock unit award granted to the reporting person."
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.
Deferred Compensation Plan financial
"pursuant to the Coherent Corp. Deferred Compensation Plan; the deferred"
A deferred compensation plan is an arrangement where an employer agrees to pay part of an employee’s pay or bonus at a later date instead of immediately, often to reduce current tax bills or to tie rewards to long-term performance. For investors it matters because these promises create future cash obligations and influence executive incentives and retention; they can affect a company’s reported liabilities, cash flow planning and the risk profile if the business faces financial trouble.
withholding tax obligations financial
"These shares were withheld by the company to discharge withholding tax obligations"
Performance Stock Units financial
"Represents shares issued upon payout of the Performance Stock Units granted"
Performance stock units are a type of company award that grants employees shares of stock only if certain performance goals are met. They motivate employees to work toward specific company achievements, aligning their interests with those of shareholders. For investors, they can influence a company's future stock supply and reflect management’s confidence in reaching key targets.
