Restricted Stock Units ("RSUs") financial

"Represents an award of Restricted Stock Units ("RSUs"). Each RSU represents a contingent right"

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 of Control financial

"earlier to occur of (a) the first anniversary ... or (b) the date that is immediately prior to the occurrence of a Change of Control"

A change of control occurs when the ownership or management of a company shifts significantly, such as through a sale, merger, or acquisition, resulting in new leadership or ownership structure. This change can impact the company's direction and decision-making, which is important for investors because it may affect the company's stability, strategy, and future prospects.
