Sono Group N.V. conducted its business through legacy solar operations via its Subsidiary during the year ended December 31, 2025. Subsequent to December 31, 2025, the company established a digital asset treasury strategy and policy. This strategy allocates the principal holding in the company's treasury reserve on its balance sheet to digital assets, primarily Bitcoin, using a covered-call yield strategy. To manage the risk associated with this strategy, on March 10, 2026, the company entered into an International Swaps and Derivatives Association, Inc.

This agreement facilitates derivative and/or hedging transactions, which may include forwards, swaps, futures, options, or other derivatives transactions related to digital assets. These transactions are governed by the ISDA Master Agreement and its related Schedule, executed on March 10, 2026. The agreement outlines certain events of default, such as failure to pay or deliver, breach of the agreement, credit support default, cross-defaults, and misrepresentation.
