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.

Class A ordinary share financial

"each RSU representing the right to receive one Class A ordinary share of the Issuer"

A Class A ordinary share is a type of common stock a company issues that carries a specific set of rights—most often particular voting power, dividend terms, or transfer rules—distinct from other share classes. For investors it matters because those rights affect control over company decisions, how income is paid out, and how easy shares are to buy or sell; think of it like a tiered ticket that gives different access and influence at the same event.

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.

Cause financial

"terminates in any vesting year other than for Cause (as defined in the applicable Award Agreement)"

pro rata financial

"shall vest pro rata based on the number of full months actually served"

Pro rata means dividing or distributing something proportionally based on a specific factor, such as ownership or contribution. For example, if an investor owns 10% of a company, they would receive 10% of any dividends or benefits allocated. This approach ensures everyone gets their fair share relative to their stake or input, helping investors understand how benefits, costs, or responsibilities are fairly shared.
