restricted stock units ("RSUs") financial

"These reported securities represent restricted stock units ("RSUs") granted on May 31, 2026 under the Issuer's 2024 Incentive Compensation Plan."

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.

2024 Incentive Compensation Plan financial

"These reported securities represent restricted stock units ("RSUs") granted on May 31, 2026 under the Issuer's 2024 Incentive Compensation Plan."

deferred stock units ("DSUs") financial

"The reported securities include (a) 15,000 deferred stock units ("DSUs") granted under the Issuer's 2012 Incentive Compensation Plan and (b) 6,629 DSUs granted under the Issuer's 2024 Incentive Compensation Plan."

beneficially owned financial

"Includes (a) 2,966 RSUs..., (b) 20,000 RSUs... and (c) 41,585 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.

separation from service financial

"The shares of common stock underlying such DSUs shall be issued upon the Reporting Person's separation from service with the Issuer."
