restricted stock units ("RSUs") financial

"Represents restricted stock units ("RSUs") granted to the Reporting Person under the Issuer's 2006 Equity and Cash Compensation Incentive 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.

Annual Meeting of Shareholders regulatory

"will vest in full on the earlier of May 8, 2027 or the date of the Issuer's 2027 Annual Meeting of Shareholders."

A yearly gathering where a company’s owners (shareholders) vote on key items like electing the board, approving executive pay, and ratifying auditors, and receive updates on performance and strategy. Think of it as an annual town hall for owners: it matters to investors because outcomes and disclosures can affect leadership, corporate direction, dividend and governance policies, and therefore the company’s risk and potential return.
