The reporting person is Bambino 255 V V UG haftungsbeschrankt, listed as a ten percent owner of Sono Group N.V. common stock and not identified as a director or officer in this filing.

How many SSM shares were sold and at what prices?

A total of 4,000 shares of Sono Group N.V. common stock were sold: 2,327 at $2.75, 946 at $2.76, 100 at $2.77, 200 at $2.765, and 427 at $2.755 per share.

Were the SSM transactions reported under a Rule 10b5-1 trading plan?

No. The document-level Rule 10b5-1 checkbox is unchecked (aff_10b5_one is false), so the reported Sono Group N.V. share sales were not affirmed as being made under a Rule 10b5-1 trading plan.

Does the Form 4 state Bambino 255 V V UG haftungsbeschrankt’s remaining SSM holdings?

No. Each transaction line shows the post-transaction holdings field as null, so the Form 4 does not report the total number of Sono Group N.V. shares held after these sales.
