Rule 12b-25 regulatory
"filed a Form 12b-25 notifying the SEC it cannot timely file its Annual Report"
Rule 12b-25 is an SEC filing provision that lets a company notify regulators and the public that it cannot file a required periodic report (like a quarterly or annual report) on time and explains the reason for the delay. For investors, the notice is a formal heads-up that financial information will arrive late—similar to a company calling to say it will be late turning in homework—so it signals increased uncertainty and may affect trading and risk assessments until the filing is available.
going concern analysis financial
"The preparation of the disclosures required... including the going concern analysis"
digital asset treasury strategy financial
"adoption of a digital asset treasury strategy, the completion of multiple financing transactions"
A digital asset treasury strategy is a plan for managing a company's or organization's digital assets, such as cryptocurrencies or digital tokens, to support its financial goals. It involves deciding how to acquire, hold, and use these assets efficiently, much like managing cash or investments, to optimize value and minimize risks. For investors, understanding this strategy helps gauge how well an organization controls its digital resources and its overall financial health.

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.

The decrease is primarily attributable to the non-recurrence of the one-time reconsolidation gain recorded in 2024 following the Registrant's regaining of control over its subsidiary Sono Motors GmbH upon the latter's exit from its Self-Administration Proceedings in February 2024.
