As previously reported, AltEnergy Acquisition Corp. (the "Company") on February 14, 2025, entered into the Amended and Restated Agreement and Plan of Merger (the "Merger Agreement") by and among the Company, Car Tech Merger Sub, LLC, Car Tech Merger Sub II, LLC, and Car Tech, LLC ("Car Tech").

On June 16, 2025, the Company received a notice (the "Termination Notice") from Car Tech stating that it was terminating the Merger Agreement pursuant to Section 10.1(i) of the Merger Agreement with immediate effect.

On June 18, 2025, the Company sent a letter to CarTech in response to the Termination Notice stating that the Company believes that the termination by Car Tech is invalid due to Car Tech's previous and continuing breaches of certain key representations, warranties and covenants under the Merger Agreement that materially contributed to the failure of the Mergers to be consummated on or before the Outside Date as provided in Section 10.1(i) of the Merger Agreement. The Company further reserved all rights in full to pursue any an all remedies available to it under the Merger Agreement and at law.

For more information concerning the Merger Agreement please see the text of the Merger Agreement which was previously filed as Exhibit 2.1 to the Company's Current Report on Form 8-K filed with the Securities and Exchange Commission on February 14, 2025, which is incorporated herein by this reference.
