Proposed Redomiciliation Transaction

On July 14, 2026, the Company’s management board and supervisory board unanimously approved a proposal to change the legal seat of the Company from the Netherlands, via Luxembourg, to the State of Delaware, to be effected through two substantially concurrent transactions: (i) a cross-border merger of the Company with and into Sono Group S.à r.l., a wholly owned Luxembourg subsidiary of the Company to be transformed into a public limited company (société anonyme) prior to the merger (“Sono Luxembourg”), with Sono Luxembourg being the surviving entity and succeeding the Company as the SEC registrant, and (ii) as soon as practicable thereafter, the conversion of Sono Luxembourg into a corporation organized under the laws of the State of Delaware under the name “Sono Group, Inc.” (collectively, the “Redomiciliation Transaction”). On July 15, 2026, Sono Luxembourg filed with the SEC a registration statement on Form S-4 (File No. 333-297478), as amended by Amendment No. 1 to the registration statement filed with the SEC on August 4, 2026 (the “Registration Statement”), which includes a proxy statement/prospectus for the extraordinary general meeting of the Company’s shareholders to be held for the purpose of voting on the Redomiciliation Transaction and the other proposals described in the Registration Statement, and which has not yet been declared effective by the SEC. Completion of the Redomiciliation Transaction is subject to, among other things, the Registration Statement having been declared effective by the SEC, receipt of the requisite approval by the Company’s shareholders, submission of a notification form to the Nasdaq Capital Market, and the lapse of certain mandatory waiting periods and the fulfillment of statutory formalities under Dutch and Luxembourg law, and there can be no assurance as to whether or when the proposed Redomiciliation Transaction will be completed. The Redomiciliation Transaction is structured to preserve shareholders’ existing economic and voting interests in the Company, and, if completed, will change only the Company’s jurisdiction of incorporation and legal form and is expected to be accounted for as a reorganization of entities under common control, with no significant impact on the Company’s consolidated financial statements, other than professional fees and other transaction costs, which are expensed as incurred. For a description of the treatment of each class of the Company’s shares in the Redomiciliation Transaction, refer to the Registration Statement.
