**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 Quarterly Report on Form 10-Q for the three months ended March 31, 2026 (the "Quarterly Report"). The preparation of the Quarterly Report presented significant accounting complexity in the current period, including: (i) the change in the Registrant's reporting currency from the euro to the U.S. dollar effective January 1, 2026, which required the recasting of all comparative prior-period financial information presented in the Quarterly Report; (ii) the first-time presentation of the Registrant's legacy solar operations as discontinued operations and the classification of the related assets and liabilities as held for sale; (iii) the first-time application of fair-value accounting for the Registrant's digital asset holdings and the accounting for complex derivative instruments arising from the Registrant's digital asset treasury strategy, including written covered call options and embedded conversion features in the Registrant's convertible debentures; and (iv) the evaluation and disclosure of the subsequent disposition of the Registrant's subsidiary, Sono Motors GmbH, on May 4, 2026. The preparation and review of the disclosures required in connection with the foregoing matters, 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 Quarterly Report 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.
