restricted stock units ("RSUs") financial

"restricted stock units ("RSUs") granted on September 30, 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.

deferred stock units ("DSUs") financial

"deferred stock units ("DSUs") granted under the Issuer's 2024 Incentive Compensation Plan"

beneficially owned regulatory

"52,485 shares of common stock beneficially owned by the Reporting Person"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
