The Sono Group N.V. (NASDAQ: SSM) SEC filings page provides access to the company’s official U.S. regulatory disclosures as a domestic filer. Sono has explained in its filings that, after it no longer qualified as a foreign private issuer as of June 30, 2024, it is required to prepare consolidated financial statements under U.S. GAAP and to submit quarterly reports on Form 10-Q, in addition to other periodic reports under the Securities Exchange Act of 1934.
Among the documents available to investors is a Form 12b-25 Notification of Late Filing related to a Form 10-Q for the period ended September 30, 2025. In that notification, Sono states that management has been finalizing accounting adjustments arising from the transition from IFRS to U.S. GAAP and the accounting for the September 5, 2025 exchange of outstanding convertible debentures into preferred shares. The filing explains that these changes affect the comparability of financial information with prior periods and that the company expects significant differences in reported net income due to prior restructuring and reconsolidation gains.
Through its periodic reports, Sono provides details on its capital structure, including the conversion of convertible debentures into preferred equity, and on its financial position and results of operations as a solar technology company focused on integrating solar solutions into commercial vehicles.
