Item 8.01 Other Events On September 5, 2025, Alternus Clean Energy, Inc. (the “Company”) effected a one-for-two hundred (1:200) reverse stock split of all issued and outstanding shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”) effective as of 12:01 a.m. Eastern Time on September 5, 2025 (the “Reverse Stock Split”), vide a Certificate of Amendment to the Third Amended and Restated Certificate of Incorporation of Alternus Clean Energy, Inc. (the “Certificate of Amendment”) filed with the Secretary of State of Delaware on September 2, 2025, and deemed effective on September 5, 2025 at 12:01 a.m. Eastern Time. As previously disclosed in the Company’s Definitive Information Statement filed on April 14, 2025, the Company’s Board of Directors (the “Board”) and the holders of a majority of the Company’s voting capital stock approved by written consent in lieu of meetings executed on March 21, 2025 a proposal authorizing an amendment to the Company’s Certificate of Incorporation to effect a reverse stock split of all issued and outstanding shares of the Common Stock at an exchange ratio ranging from one-for-two (1:2) to one-for-five hundred (1:500), with such reverse stock split to be effected at an exchange ratio and at such a date and time, if at all, as determined by the Board in its sole discretion. The Board subsequently determined to effect a 1:200 reverse stock split effective as of 12:01 a.m. Eastern Time on September 5, 2025 (the “Reverse Stock Split”). As a result of the Reverse Stock Split, every two hundred (200) shares of issued and outstanding Common Stock combined into one (1) validly issued, fully paid and nonassessable share of Common Stock. The Reverse Stock Split uniformly affected all issued and outstanding shares of Common Stock and did not alter any stockholder’s percentage ownership interest in the Company, except to the extent of the Reverse Stock Split’ results in the fractional interests. No fractional shares were issued in connection with the Reverse Stock Split. Stockholders who otherwise would have been entitled to receive fractional shares of Common Stock received an amount in cash (without interest or deduction) equal to the fraction of one share to which such stockholder would otherwise be entitled multiplied by the share price, representing the product of the average closing price of the Company’s common stock on the OTCQB Market for the five consecutive trading days immediately preceding the effective date of the Reverse Stock Split and the inverse of the Reverse Stock Split ratio. Proportional adjustments have also been made to the Company’s outstanding warrants, stock options, and convertible securities, as well as to the reserves available pursuant to the terms of the Company’s 2023 Equity Incentive Plan to reflect the Reverse Stock Split, in each case, in accordance with the terms thereof. The Reverse Stock Split reduced the number of shares of Common Stock issued and outstanding from the earlier 138,056,533 to 690,282 shares of Common Stock. The number of authorized shares of Common Stock did not change by the Reverse Stock Split. The Company’s transfer agent, Equiniti Trust Company, LLC (formerly known as American Stock Transfer & Trust Company) (“Equiniti”) acted as the exchange agent for the reverse stock split. Instructions regarding the exchange of stock certificates, as applicable, were provided to stockholders of record as of September 4, 2025 by Equiniti. Stockholders who held their shares in brokerage accounts or “street name” were not required to take any action to effect the exchange of their shares. The Common Stock started trading on a split-adjusted basis on the OTCQB Market at the market open on September 5, 2025. The trading symbol for the Common Stock remains “ALCE.” Following the Reverse Stock Split, the CUSIP for the Company’s Common Stock is 02157G 309. The description of the Certificate of Amendment and the Reverse Stock Split is qualified in its entirety by reference to the text of the Certificate of Amendment, which is filed as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference. On September 3, 2025, the Company issued a press release announcing the Reverse Stock Split. The full text of the Company’s press release issued in connection with the foregoing matter is filed as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
