restricted stock units ("RSUs") financial

"Represents restricted stock units ("RSUs") granted to the reporting person on June 11, 2026."

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.

Nonqualified Deferred Compensation Plan for Non-Employee Directors financial

"Pursuant to the Issuer's Nonqualified Deferred Compensation Plan for Non-Employee Directors, the reporting person has deferred delivery"

change in control financial

"within 30 days of the earlier of (i) separation of service or (ii) a change in control (the "Delivery Date")."

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.

Vesting Date financial

"Such RSUs will vest on June 11, 2027, or if sooner, immediately prior to the election ... (the "Vesting Date")."
