Sono Group N.V. announced its commitment to change its business model to focus exclusively on its solar business for B2B customers and to terminate the Sion passenger car program. This has led to a shift in the Company's business model and operations away from its supervisory board members' strong expertise in the areas of automotive, digitalization, and Community-focus. Against this background four members of the Company's supervisory board, Chair Martina Buchhauser, Vice-Chair Robert Jeffe, Arnd Schwierholz, and Community Representative Sebastian Böttger, 21 April 2023, announced their resignation with immediate effect.

Johannes Tischler, who was nominated to the supervisory board by Laurin Hahn, will continue to serve on the Company's supervisory board and the supervisory board can thus continue to perform its duties. The Company has commenced the process of finding suitable candidates to fill the vacancies on its supervisory board as promptly as reasonably practicable, taking into account the Company's nomination arrangement pursuant to which the Company's Co-CEOs and Co-Founders, Laurin Hahn and Jona Christians, acting individually, are each permitted to make a binding nomination for one supervisory board member. Once suitable candidates have been identified, the Company shall convene a general meeting of shareholders to appoint them.

As a consequence of the resignation of all members of the Company's supervisory board except Johannes Trischler described above, the Company will not have any supervisory board committees until new candidates for the Company's supervisory board have been identified and appointed.
