The Company has its management in the United States of America since January 31, 2024. Prior to this date, the Company’s management was based in Germany. The business address of the Company is Waldmeisterstraße 93, 80935 Munich, Germany (trade register number: 80683568).

Sono N.V.’s wholly-owned subsidiary Sono Group S.à r.l., a private limited liability company (société à responsabilité limitée) incorporated under the laws of the Grand Duchy of Luxembourg, having its registered office at 8 Avenue de la Gare, L-1610 Luxembourg, Grand Duchy of Luxembourg. Such subsidiary was funded with €12,000 for purposes of providing share capital, and it has no operations at this time. Sono N.V. is the ultimate parent of the Group. Hereinafter, Sono N.V. and its consolidated subsidiary collectively are referred to as “Sono Group”, or the “Group”, “Management”, “we” and “us”.

Sono Group intended to develop and manufacture electric vehicles with integrated solar panels (the “Sion passenger car program”). In addition, it planned to license its solar technology to other Original Equipment Manufacturers (“OEMs”). However, on February 24, 2023, Sono Group announced the decision to terminate the Sion passenger car program and to pivot the business model to exclusively retrofitting and integrating Sono Group’s solar technology onto third party vehicles due to lack of available funding. As a consequence, management decided to apply for the opening of the self-administration proceedings with respect to Sono N.V. and Sono Motors (the “Self-Administration Proceedings”) on May 15, 2023. The Subsidiary withdrew its application for Preliminary Self-Administration Proceedings (as defined herein) on January 31, 2024, and the Subsidiary exited its Self-Administration Proceedings on February 29, 2024. Subsequent to December 31, 2025, the Company's management board, with the approval of the supervisory board, adopted the Treasury Strategy (as defined herein), under which the principal holding in the Company's treasury reserve will be allocated to digital assets, principally Bitcoin, by applying a covered-call yield strategy. In connection with the Treasury Strategy, the Company entered into a series of agreements with Blockchain.com (BVI) II Limited to facilitate related derivative and hedging transactions. Concurrently, the Company determined to cease funding to the Subsidiary (Sono Motors GmbH) and to initiate its exit from the legacy solar operations. The Company intends to solicit the ratification by its shareholders of the engagement by the Company in the Treasury Strategy. See “Note 16 Subsequent Events” and “Note 3 Liquidity and Going Concern” for additional information.
