Item 8.01. Other Events.

On ~~July~~August 2522, 2024, TortoiseEcofin Acquisition Corp. III ~~(the “Company”) received a letter from One Energy Enterprises Inc.~~, a ~~Delaware~~Cayman ~~corporation~~Islands ~~(“One~~exempted ~~Energy”),~~company ~~purporting to unilaterally terminate the Amended and Restated Business Combination Agreement~~ (~~as may be amended, restated or supplemented from time to time,~~ the “~~Business Combination Agreement~~Company”), ~~which~~issued ~~was~~a ~~entered~~press ~~into~~release onannouncing ~~February 14,~~its ~~2024,~~intent byto ~~and~~liquidate ~~among~~as ~~the~~soon ~~Company,~~as ~~One Energy and the other parties thereto~~practicable. ~~The~~A ~~Company~~copy ~~has responded to One Energy’s letter disputing One Energy’s ability to terminate the contemplated transactions under the terms~~ of the ~~Business~~press ~~Combination~~release ~~Agreement,~~with ~~which,~~respect into the ~~Company’s~~liquidation ~~view,~~is ~~remains~~attached ~~in effect~~ as ofExhibit ~~the date of this current report~~99.1 ~~The~~hereto ~~Company~~and is ~~exploring~~incorporated ~~all~~herein ofby ~~its legal options~~reference.

As previously disclosed, on July 25, 2024, the Company received a notice from One Energy Enterprises Inc. (“One Energy”) purporting to unilaterally terminate the Amended and Restated Business Combination Agreement, dated as of February 14, 2024, between the parties (the “Business Combination Agreement”), due to the suspension of the Company’s securities from trading on the New York Stock Exchange. The Company has responded to One Energy’s notice rejecting One Energy’s ability to terminate the proposed business combination (the “Business Combination”) under the terms of the Business Combination Agreement, and in the Company’s view, the Business Combination Agreement remains in effect. Although the Company is exploring all of its legal options, it does not expect that the Business Combination will be completed and does not intend to seek a business combination with another target.

In view of the foregoing, the Board of Directors of the Company has determined to liquidate the trust account and the Company’s sponsor will not make any further contributions to the Company’s trust account.

The Company expects to redeem all of its outstanding Class A ordinary shares for a pro rata amount of the principal and accrued interest in the trust account after the payment of taxes and dissolution expenses (the “Redemption Amount”). On or about the close of business on September 6, 2024, the Class A ordinary shares will be deemed canceled and will represent only the right to receive the Redemption Amount. The Redemption Amount will be payable to the holders of Class A ordinary shares through the facilities of Continental Stock Transfer & Trust Company, the Company’s transfer agent.
