Form 8-K Filing Summary

MGE Energy, Inc. held its Annual Meeting of Shareholders on May 19, 2026. During the meeting, three Class I Directors were elected, shareholders ratified the selection of PricewaterhouseCoopers LLP as the independent registered public accounting firm for 2026, and an advisory vote on executive compensation was approved. The voting results for the election of directors, ratification of the auditor, and the advisory vote on executive compensation are detailed in the filing. It was also noted that a provision in the company's Amended and Restated Articles of Incorporation limits the voting power of shareholders who own more than 10% of the outstanding voting stock, reducing their vote to 1/100th per share for shares exceeding this threshold. This limitation was applied to two shareholders.
