ITEM 4.01

Changes in Registrant’s Certifying Accountant

On April 14, 2025, AltEnergy Acquisition Corp. (the “Company”) was notified by Marcum LLP (“Marcum”) that Marcum resigned as the Company’s independent registered accounting firm. On November 1, 2024, CBIZ CPAs P.C. (“CBIZ”) acquired the attest business of Marcum. On April 15, 2025, following the approval of the Audit Committee of the Company’s Board of Directors, CBIZ was engaged, effective immediately, as the Company’s independent registered public accounting firm for the year ended December 31, 2025.

The reports of Marcum regarding the Company’s financial statements for the years ended December 31, 2024 and December 31, 2023, did not contain any adverse opinion or disclaimer of opinion. Each such report did contain a “going concern” qualification based on management’s determination that in each year it was uncertain that the Company would be able to consummate an initial business combination prior to the then deadline in the Company’s Certificate of Incorporation that required the Company to consummate an initial business combination by such date or thereafter mandatorily liquidate. Accordingly, the reports for each such year stated that these conditions raise substantial doubt about the ability of the Company to continue as a going concern, and that the financial statements did not include any adjustments that might result from the outcome of that uncertainty.

During the years ended December 31, 2024 and December 31, 2023, and through April 14, 2025, the date of Marcum’s resignation, there were (a) no disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) with Marcum on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of Marcum, would have caused Marcum to make reference to such disagreement in its report and (b) no “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K and the related instructions), except for:

As disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024:

Our principal executive officer and principal financial and accounting officer evaluated the effectiveness of our disclosure control and procedures as of December 31, 2023. Based on this evaluation, the Company’s principal executive officer and principal financial officer concluded that certain disclosure controls and procedures were not effective as of December 31, 2022 due to material weaknesses that existed related our accounting for complex financial instruments and our accounting and reporting for the completeness and accuracy of warrant liabilities and the corresponding change in the fair value of the warrant liability, that led to the restatement of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

Management additionally identified, as it relates to the material weakness discussed above relating to the accounting for complex financial instruments, a failure to properly record the capital contributions and related costs associated with non-redemption agreements entered into with certain stockholders of the Company in connection with the special meeting of stockholders of the Company held on April 28, 2023 that led to the restatement of the Company’s Quarterly Report on Form 10-Q for the quarterly periods ended June 30, 2023 and September 30, 2023.

In addition, management identified a material weakness in relation to the accounting of contractual liabilities which led to errors in our financial statements in the accounting of consulting fees pursuant to a consulting agreement with our chief financial officer that led to the restatement of the Company’s Quarterly Report on Form 10-Q for the quarterly periods ended March 31, 2023, June 30, 2023, and September 30, 2023.

The above reportable events were discussed between the Audit Committee and Marcum. Marcum has been authorized by the Company to respond fully to the inquiries of CBIZ, the successor independent registered public accounting firm, concerning these reportable events.

During the years ended December 31, 2024 and December 31, 2023, and through April 14, 2025, the date Marcum informed the Company of their resignation, neither the Company nor anyone on the Company’s behalf consulted with CBIZ regarding (i) the application of accounting principles to a specific completed or contemplated transaction or regarding the type of audit opinions that might be rendered by CBIZ on the Company’s financial statements, and CBIZ did not provide any written or oral advice that was an important factor considered by the Company in reaching a decision as to any such accounting, auditing, or financial reporting issue or (ii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions), as that term is described in Item 304(a)(1)(iv) of Regulation S-K, or a reportable event, as that term is defined in Item 304(a)(1)(v) of Regulation S-K.

The Company provided Marcum with a copy of this Current Report on Form 8-K prior to its filing with the U.S. Securities and Exchange Commission (the “SEC”) and requested that Marcum furnish the Company with a letter addressed to the SEC, pursuant to Item 304(a)(3) of Regulation S-K, stating whether it agrees with the above statements made by us in response to Item 304(a) of Regulation S-K and, if it does not agree, the respects in which it does not agree, as required under Item 304(a)(3) of Regulation S-K. A copy of Marcum’s letter, dated April 15, 2025, is filed as Exhibit 16.1 (which is incorporated by reference herein) to this Current Report on Form 8-K.
