Key Terms

4 terms

restricted stock units financial

"Represents an award of restricted stock units ("RSUs") granted on June 30, 2026"

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.

incentive award letter agreement financial

"RSUs granted on June 30, 2026 pursuant to an incentive award letter agreement"

vest financial

"The RSUs will vest upon the earlier of (i) June 30, 2027 or (ii) termination of employment"

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.

contingent right financial

"Each RSU represents a contingent right to receive one share of the Issuer's common stock"
