ALLETE, Inc. disclosed a potential "stub period" dividend tied to its pending merger with Alloy Parent LLC. Under the merger agreement dated May 5, 2024, a dividend may be calculated pro rata based on the number of days from the record date for the last quarterly dividend and a 91-day divisor used to compute a daily dividend rate. On October 5, 2025 the Board set the record date at October 16, 2025 for shareholders who would be eligible if the Board later declares the Stub Period Dividend. The Board has not yet declared an amount or payment date; payment would require Closing of the merger and regulatory approval from the Minnesota Public Utilities Commission. Holders must retain shares through Closing to receive any payment, and there is no assurance the Board will declare the dividend.
