restricted stock units financial

"These shares represent an award of restricted stock units ("RSUs") granted"

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.

continuous service relationship financial

"subject to the Reporting Person's continuous service relationship with the Issuer"

vesting commencement date financial

"following the vesting commencement date of August 15, 2026"

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.

contingent right financial

"Each RSU represents a contingent right to receive one share"
