restricted stock units financial

"Represents shares of the Registrant's common stock underlying restricted stock units ("RSUs") granted on October 20, 2025"

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.

Vesting Commencement Date financial

"RSUs granted on October 20, 2025 (the "Vesting Commencement Date") which vest, subject to the reporting person's continuous service"

The vesting commencement date is the starting point when an employee begins earning ownership rights to their promised benefits, such as stock options or retirement contributions. Think of it like the day a savings account is opened—only after this date do the benefits start to grow and become fully available over time. It matters to investors because it marks when the clock begins ticking toward full ownership, affecting the timing and value of these benefits.

continuous service financial

"RSUs will vest on the first anniversary of the Vesting Commencement Date; and vesting is subject to the reporting person's continuous service"

quarterly vesting dates financial

"one-twelfth (1/12th) of the RSUs will vest on each of the eight quarterly vesting dates (i.e., October 20, January 20, April 20, and July 20)"
