Item 4.01 Changes in Registrants’ Certifying Accountant.

Alternus Clean Energy, Inc. (the “Company”), was notified that Mazars USA LLP (“Mazars”), the Company’s independent registered public accounting firm, entered into a transaction with FORVIS, LLP (“FORVIS”) whereby substantially all of the partners and employees of Mazars joined FORVIS. As a result on the effective date of June 1, 2024, FORVIS, LLP changed its name to Forvis Mazars, LLP (“Forvis Mazars”) and Mazars resigned as the Company’s independent registered public accounting firm. The Audit Committee of the Company’s Board of Directors has appointed Forvis Mazars to serve as the Company’s independent registered public accounting firm effective June 1, 2024.

The audit report of Mazars on the financial statements of the Company as of December 31, 2023 did not contain an adverse opinion or a disclaimer of opinion, and was not qualified or modified as to uncertainty, audit scope or accounting principles.

During the Company’s fiscal year ended December 31, 2023, and the subsequent period through the date of this Current Report on Form 8-K, there were (i) no disagreements (as such term is used in Item 304(a)(1)(iv) of Regulation S-K) between the Company and Mazars on any matters of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreement(s), if not resolved to the satisfaction of Mazars, would have caused Mazars to make reference to the subject matter of the disagreement(s) in connection with its report on the Company’s financial statements and (ii) no reportable events within the meaning set forth in Item 304(a)(1)(v) of Regulation S-K.

During the Company’s fiscal year ended December 31, 2023, and the subsequent period through the date of this report, neither the Company nor any party acting on behalf of the Company consulted with Forvis Mazars regarding any of the matters set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.

The Company has provided Mazars a copy of the disclosures in this Form 8-K and has requested that Mazars furnish it with a letter addressed to the Securities and Exchange Commission stating whether or not Mazars agrees with the Company’s statements in this Item 4.01. A copy of the letter dated June 6, 2024 furnished by Mazars in response to that request is filed as Exhibit 16.1 to this Current Report on Form 8-K.
