Commission File No.: 001-41066

Subject Company: Sono Group N.V.

There are 124 franchises across the NFL, NBA, MLB and NHL. Owning a piece of one has meant an eight- or nine-figure check and an invitation.

That has started to shift. Over the past several years, each of the four leagues adopted a framework permitting passive institutional ownership — the NFL most recently, in August 2024.

Sono Group N.V. (Nasdaq: SSM) has signed a non-binding letter of intent to combine with Sports One, a company formed to acquire and hold minority interests in professional sports teams across those leagues, and to operate a sports intelligence business that puts a measurable value on athletes — including their name, image and likeness (NIL) rights.

The proposed combination would give that strategy a public, permanent-capital structure: no fixed fund life, no forced exit timeline, and shares any investor can buy.

Concurrently with signing, a group of investors purchased 283,500 ordinary shares — 19.9% of our outstanding ordinary shares — at market price, with no discount, no warrant coverage, and a 180-day lock-up.

The letter of intent is non-binding. Completion remains subject to definitive documentation, due diligence, regulatory review and shareholder approval.
