An ordinary general meeting of shareholders is a company’s regular annual meeting where owners vote on routine but important matters such as electing the board, approving financial statements, appointing auditors and deciding dividend policy. Think of it like an annual homeowners’ meeting where basic rules, budget items and leadership are confirmed; its results directly affect corporate oversight, financial reporting and distributions, so investors monitor it for governance and payout signals.
