1. Organization and Formation

Alternus Clean Energy, Inc. (the “Company”) was incorporated in Delaware on May 14, 2021 and was originally known as Clean Earth Acquisitions Corp. (“Clean Earth”).

On October 12, 2022, Clean Earth entered into a Business Combination Agreement, as amended by that certain First Amendment to the Business Combination Agreement, dated as of April 12, 2023 (the “First BCA Amendment”) (as amended by the First BCA Amendment, the “Initial Business Combination Agreement”), and as amended and restated by that certain Amended and Restated Business Combination Agreement, dated as of December 22, 2023 (the “A&R BCA”) (the Initial Business Combination Agreement, as amended and restated by the A&R BCA, the “Business Combination Agreement”), by and among Clean Earth, Alternus Energy Group Plc (“AEG”) and the Sponsor. Following the approval of the Initial Business Combination Agreement and the transactions contemplated thereby at the special meeting of the stockholders of Clean Earth held on December 4, 2023, the Company consummated the Business Combination on December 22, 2023. In accordance with the Business Combination Agreement, Clean Earth issued and transferred 11,500 shares of common stock of Clean Earth, par value $0.0001 per share, to AEG, and AEG transferred to Clean Earth, and Clean Earth received from AEG, all of the issued and outstanding equity interests in the Acquired Subsidiaries (as defined in the Business Combination Agreement) (the “Equity Exchange,” and together with the other transactions contemplated by the Business Combination Agreement, the “Business Combination”). In connection with the Closing, the Company changed its name from Clean Earth Acquisition Corp. to Alternus Clean Energy, Inc.

Clean Earth’s (SPAC) only pre-combination assets were cash and investments and the SPAC did not meet the definition of a business in accordance with U.S. GAAP. Therefore, the substance of the transaction was a recapitalization of the target (AEG) rather than a business combination or an asset acquisition. In such a situation, the transaction is accounted for as though the target issued its equity for the net assets of the SPAC and, since a business combination has not occurred, no goodwill or intangible assets would be recorded. As such, AEG was considered the accounting acquirer and these consolidated financial statements represent a continuation of the consolidated financial statements of the AEG Acquired Subsidiaries. Assets and liabilities of AEG are presented at their historical carrying values.

Alternus Clean Energy Inc. is a holding company that operates through the following 8 subsidiaries as of September 30, 2025:
