**PART III - NARRATIVE** 

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Sono Group N.V.'s (the "Registrant") management has been working to finalize the Registrant's Annual Report on Form 10-K for the fiscal year ended December 31, 2025. The Registrant experienced turnover of certain key members of its internal accounting staff, which required additional time to complete the preparation and review of the financial statements and related disclosures. In addition, subsequent to December 31, 2025, the Registrant underwent a significant strategic transformation, including the adoption of a digital asset treasury strategy, the completion of multiple financing transactions, and the initiation of its exit from the legacy solar operations. The preparation of the disclosures required in connection with these subsequent events, including the going concern analysis and the Subsequent Events note, required additional time and coordination with the Registrant's independent registered public accounting firm. As a result, the Registrant is unable to file its Annual Report on Form 10-K within the prescribed time period without unreasonable effort or expense. The Registrant expects to be able to file within the additional time allowed by this report.
