Key Terms

4 terms

Restricted Stock Units financial

"granted in the form of Restricted Stock Units"

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.

Performance Share Units financial

"granted in the form of Performance Share Units"

Performance share units are a type of company stock award given to employees that depend on the company meeting specific goals or targets. If these goals are achieved, the employee receives shares or the value of shares; if not, they may receive little or no compensation. This aligns employees’ interests with the company's success and encourages performance that benefits investors.

stockholders of record regulatory

"to stockholders of record as of September 18, 2026"

Stockholders of record are the people or entities whose names appear on a company's official shareholder list on a specific cutoff date set by the company or its transfer agent; only those listed are entitled to receive dividends, vote at shareholder meetings, or participate in other corporate actions. Think of it like a guest list for an event: being on the list on the set day determines who gets the benefits and rights, so investors must own shares before the cutoff to qualify.

vest financial

"These RSUs will vest and are payable concurrent with the underlying RSUs."

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.
