Restricted Stock Agreement financial

"subject to the terms of the Restricted Stock Agreement"

Annual Meeting of shareholders regulatory

"vest on the earlier of the 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.
