Postponement of Extraordinary General Meeting

On April 15, 2024, TortoiseEcofin Acquisition Corp. III (the “Company”) postponed its extraordinary general meeting (the “Meeting”) originally scheduled for April 18, 2024 to 9:30 a.m. Eastern Time on April 19, 2024. As a result of this change, the date and time by which shareholders seeking to exercise their redemption rights in connection with the Meeting must tender their public shares physically or electronically and submit a request in writing that the Company redeem their public shares for cash is being extended to 5:00 p.m., Eastern Time, on April 17, 2024 (two business days before the Meeting).

The Company has previously called and provide a notice of the Meeting to consider and vote upon the matters described in the Company’s definitive proxy statement filed with the Securities and Exchange Commission (the “SEC”) on March 29, 2024 (as may be amended, the “Proxy Statement”). At the Meeting, shareholders will be asked to vote on a proposal to approve an extension of the date by which the Company must consummate an initial business combination from April 22, 2024 on a monthly basis up to six times until October 22, 2024, or such earlier date as determined by the Company’s board of directors (the “Extension Amendment Proposal”). Defined terms used but not defined herein have the meanings set forth in the Proxy Statement.

Contribution for Charter Extension

While the Proxy Statement does not provide for any contribution to the Company’s trust account (“Trust Account”) in connection with the Extension Amendment Proposal, TortoiseEcofin Sponsor III LLC, the Company’s sponsor (the “Sponsor”), has agreed that if the Extension Amendment Proposal is approved and implemented, it or its designee will contribute to the Company, as a loan, $0.015 for each Public Share that is not redeemed in connection with the Charter Extension for each calendar month (commencing on April 23, 2024 and on the 23rd day of each subsequent month) until the Charter Extension Date, or portion thereof, that is needed to complete a Business Combination (such loans, the “Contribution”), which amount will be deposited into the Trust Account.

Assuming the Extension Amendment Proposal is approved, the initial Contribution amount will be deposited into the Trust Account promptly following the Prior Termination Date. Each additional monthly Contribution will be deposited in the Trust Account within seven calendar days from the 23rd day of such calendar month. The Contributions are conditioned upon the implementation of the Charter Extension. The Contributions will not be made if the Charter Extension is not approved or the Charter Extension is not completed. The amount of the Contributions, which are loans, will not bear interest and will be repayable by us to the Sponsor or its designees upon consummation of a Business Combination. If the Sponsor or its designees advises us that it does not intend to make the Contributions, then the Extension Amendment Proposal and the Adjournment Proposal will not be put before the shareholders at the Meeting and the Company will wind up, liquidate and dissolve in accordance with the Memorandum and Articles of Association. the Company’s board of directors will have the sole discretion whether to extend for additional calendar months following April 22, 2024 until October 22, 2024 and if the Company’s board of directors determines not to continue extending for additional calendar months, the Sponsor or its designees will not make any additional Contributions following such determination.

The Company plans to continue to solicit proxies from shareholders during the period prior to the Meeting. Only the holders of the Company’s ordinary shares as of the close of business on March 11, 2024, the record date for the Meeting, are entitled to vote at the Meeting.

Participants in the Solicitation

The Company and its directors and executive officers and other persons may be deemed to be participants in the solicitation of proxies from the Company’s shareholders in respect of the matters to be voted on at the Meeting. Information regarding the Company’s directors and executive officers is contained in the Proxy Statement.

No Offer or Solicitation

This communication shall not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any jurisdiction in which the offer, solicitation or sale would be unlawful prior

to the registration or qualification under the securities laws of any such jurisdiction. No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended (the “Securities Act”).

Additional Information

The Company has filed the Proxy Statement with the SEC in connection with the Meeting and, beginning on April 1, 2024, mailed the Proxy Statement and other relevant documents to its shareholders as of March 11, 2024, the record date for the Meeting. The Company’s shareholders and other interested persons are advised to read the Proxy Statement and any other relevant documents that have been or will be filed with the SEC in connection with the Company’s solicitation of proxies for the Meeting because these documents will contain important information about the Company, the matters to be voted on at the Meeting and related matters. Shareholders may also obtain a free copy of the Proxy Statement, as well as other relevant documents that have been or will be filed with the SEC, without charge, at the SEC’s website located at www.sec.gov or by directing a request to Advantage Proxy, Inc. at (877) 870-8565 or by email at ksmith@advantageproxy.com.

Forward-Looking Statements

This Current Report on Form 8-K (the “Current Report”) and oral statements made from time to time by representatives of the Company may include “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended.

All subsequent written or oral forward-looking statements attributable to the Company or persons acting on its behalf are qualified in their entirety by this paragraph.
