Restricted Stock Units financial

"Each restricted stock unit ("RSU") represents a contingent right"

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.

contingent right financial

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

vest financial

"The RSUs will vest in substantially equal increments on each of September 30, 2026"

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.

canceled prior to vest date financial

"RSUs do not expire; they either vest or are canceled prior to vest date"
