INTRODUCTORY NOTE

 

This Current Report on Form 8-K is being filed in connection with the completion of the transactions contemplated by that certain Agreement and Plan of Merger, dated as of May 5, 2024 (the “Merger Agreement”), by and among ALLETE, Inc., a Minnesota corporation (the “Company”), Alloy Parent LLC, a Delaware limited liability company (“Parent”), and Alloy Merger Sub LLC, a Delaware limited liability company and wholly owned subsidiary of Parent (“Merger Sub”). Pursuant to the Merger Agreement, at the effective time of the Merger (defined below) (the “Effective Time”) on December 15, 2025 (the “Closing Date”), Merger Sub merged with and into the Company (the “Merger”), with the Company continuing as the surviving corporation and becoming a wholly owned subsidiary of Parent (the Company, as the surviving corporation of the Merger, is sometimes referred to herein as the “Surviving Corporation”).

 

As a result of the Merger, each share of common stock, without par value, of the Company (the “Common Stock”) issued and outstanding immediately prior to the Effective Time (other than shares of Common Stock held by any holder who properly exercised dissenters’ rights under Minnesota law in respect of such shares and any shares of Common Stock held by an affiliate of Parent) was cancelled and converted into the right to receive $67.00 in cash, without interest (the “Merger Consideration”).

 

In addition, at the Effective Time, each restricted stock unit with respect to Common Stock subject to time-based vesting that was outstanding immediately prior to the Effective Time (“RSU”) was cancelled and converted into a contingent right to receive an amount in cash, without interest, equal to the Merger Consideration, payable (i) in the case of such right converted from unvested RSUs, upon the same vesting conditions as applied to the corresponding RSU, (ii) in the case of such right converted from vested RSUs, as soon as reasonably practicable following the Closing Date, or (iii) in the case of such right converted from deferred stock units (“DSUs”), in accordance with the same terms and conditions, including elections with respect to time of payment, as applied to the corresponding DSUs immediately prior to the Effective Time. Each performance share award with respect to Common Stock that was outstanding and unvested immediately prior to the Effective Time was cancelled and converted into a right to receive, without interest, the Merger Consideration multiplied by the number of shares of Common Stock subject to the award, determined based on attainment of the greater of target and actual performance as of the last business day immediately preceding the Closing Date. A pro rata portion (based on the elapsed portion of the performance period at that time) of the converted performance share awards will be paid out as soon as reasonably practicable following the Closing Date, with the remainder of the award being subject to time-vesting for the remainder of the applicable performance period. Further, purchase rights accumulated during the offering period in effect under the Company’s Employee Stock Purchase Plan (the “ESPP”) preceding the Closing Date were automatically exercised into shares of Common Stock prior to the Closing Date, and the ESPP was terminated as of immediately prior to the Closing Date. For additional information regarding the Merger Agreement’s treatment of these compensatory awards, please see the Company’s definitive proxy statement on Schedule 14A filed with the U.S. Securities and Exchange Commission (the “SEC”) on July 10, 2024, which is incorporated herein by reference.

Trading of Common Stock on the NYSE was suspended prior to the opening of trading on the Closing Date, and the delisting of the Common Stock from the NYSE will be effective 10 days after the filing of the Form 25.

 

Additionally, the Company intends to file a certification and notice of termination of registration on Form 15 with the SEC to terminate the registration of its shares under Section 12(g) of the Exchange Act and to suspend its reporting obligations under Sections 13 and 15(d) of the Exchange Act with respect to the Common Stock.

On December 14, 2025, the board of directors of the Company declared, subject to the consummation of the Merger, a “stub period” dividend in an amount equal to $0.008 per share of Common Stock (which reflects the most recent regular quarterly dividend rate of $0.73 per share, divided by 91 days) multiplied by the number of days from and including August 16, 2025, the day after the record date for the most recent regular quarterly Common Stock dividend, to and including the Closing Date (the “Stub Period Dividend”).
