Sono Group N.V. Reports Strong Commercial Momentum at Major European Trade Shows; Expands Market Reach with Dual November Exhibitions

Munich, Oct. 29, 2025 (GLOBE NEWSWIRE) -- Sono Group N.V. (NASDAQ:SSM) (hereafter referred to as "Sono" or the "Company", parent company to Sono Motors GmbH, hereafter referred to as "Sono Solar" or "Subsidiary"), the solar technology company, today announced significant commercial progress by its operating subsidiary Sono Solar following successful exhibitions at NUFAM (Karlsruhe) and Busworld Europe (Brussels), where the company's solar-integration technology attracted substantial interest from European OEMs, Tier-1 suppliers, and commercial fleet operators. Sono Group confirmed that Sono Solar will participate in two simultaneous industry-leading trade shows in November, SOLUTRANS in Lyon and METSTRADE in Amsterdam, to capitalize on opportunities in both road-transport and marine segments.



Validated Commercial Traction at NUFAM and Busworld



At NUFAM (September 25–28, Karlsruhe), Sono Solar showcased commercially viable solar applications for the commercial-vehicle sector, including solutions for liftgate power, telematics, idle-reduction, and auxiliary-battery life extension. The exhibition featured a fully integrated refrigerated-trailer solution developed with established partner MTTE (Mitsubishi Heavy Industries – Thermal Transport Europe), combining MTTE's electric transport refrigeration unit (eTRU) and battery pack with Sono Solar's photovoltaic modules and proprietary intelligent charge controller. The system was presented directly to target customers, generating qualified leads in temperature-controlled logistics.



At Busworld Europe (October 4–9, Brussels), MAN, one of Europe's leading bus and coach manufacturers, premiered their first fully electric coach, MAN Lion's Coach E, and showcased the vehicle with Sono Solar's fully operational Bus Kit; the world-premiere coach also won the show's sustainability award. This MAN-endorsed demonstration marked a significant validation milestone and underscored the technical maturity and commercial readiness of Sono Solar's integration platform for transport applications, generating a robust pipeline of follow-on discussions with multiple manufacturers and Tier-1 suppliers.



Expanding Presence Across Multiple Segments in November



SOLUTRANS 2025 (Lyon Eurexpo, November 18–22): Europe's leading road and urban-transport exhibition, where Sono Solar will advance customer and partner discussions across trailer, truck, and van segments.



METSTRADE 2025 (RAI Amsterdam, November 18–20): The world's largest marine-equipment trade show, where Sono Solar will pursue opportunities in marine applications. Building on growing inbound interest from marine OEMs and system integrators, Sono Solar will highlight its intelligent charge-controller technology, designed for mobile use and capable of directly charging traction (drive) batteries rather than auxiliary systems only, presented together with a long-standing module partner.



Commercial and Strategic Outlook



Public on-vehicle demonstrations by established OEMs at NUFAM and Busworld validate Sono Solar's integration approach and support ongoing commercialization across temperature-controlled logistics and commercial transport. Rising interest from marine industry players further underscores the versatility of the company's core technology, which enables direct high voltage battery charging to extend range and reduce operating costs across diverse mobile platforms.
