RSU financial

"Each RSU represents a contingent right to receive one Class A ordinary share."

Restricted stock units (RSUs) are a form of company shares given to employees as part of their compensation, usually with certain restrictions or conditions, such as remaining with the company for a set period. When these restrictions lift, employees receive actual shares that they can sell or hold. For investors, RSUs can impact a company's stock supply and reflect the company's commitment to attracting and retaining talent.

ADSs financial

"in the form of 1,464 ADSs of the Issuer to satisfy tax withholding obligations"

vesting commencement date financial

"with a grant date of May 12, 2026 and a vesting commencement date of May 12, 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.

vest pro rata financial

"the portion otherwise scheduled to vest for such vesting year shall vest pro rata"
