Restricted Stock Units ("RSUs") financial

"Represents Restricted Stock Units ("RSUs"). All of the RSUs subject to this Award will vest..."

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

Change in Control financial

"In addition, all such RSUs will vest upon a Change in Control (as defined in the Plan)..."

A "change in control" occurs when the ownership or management of a company shifts significantly, such as through a merger, acquisition, or sale of a large part of its assets. This change can impact how the company is run and may influence its future direction. For investors, it matters because it can affect the company's stability, strategy, and value, often signaling potential changes in investment risk or opportunity.

Continuous Service financial

"Notwithstanding the foregoing, vesting shall terminate upon the Participant's termination of Continuous Service."

annual meeting of stockholders financial

"will vest upon the earlier of June 3, 2027 and the Company's next annual meeting of stockholders."
