What Leoni AG does
Leoni AG is a Nuremberg, Germany-headquartered provider of energy and data management solutions for the global automotive industry, organized into two principal operating divisions: the Wiring Systems Division (WSD), which designs and manufactures complete low-voltage and high-voltage wiring harness systems for passenger vehicles, commercial vehicles, and special vehicles, and the Automotive Cable Solutions (ACS) division, which produces standard automotive cables, special cables, and EV charging cables under the LEONI EcoSense brand. The company supplies directly to automotive OEMs through embedded engineering and account management, with multi-year quote-based contracts and just-in-time delivery from 100+ production sites across Europe, Africa, North America, South America, and Asia. Its product portfolio spans traditional 12V harnesses, high-voltage 400V-800V architectures for battery-electric and hybrid vehicles, specialized high-voltage battery integration solutions, liquid-cooled high-power charging (HPC) cable systems for ultrafast EV charging, and emerging zonal-architecture wiring with distributed zone controllers designed to replace centralized harnesses. The company also offers the LIMEVERSE 100% circular cable line under its ReWire sustainability program, targeting 50% product CO2 footprint reduction and climate neutrality by 2045.
Leoni generates revenue primarily through hardware sales of these wiring systems and cable solutions, serving passenger vehicle OEMs, commercial vehicle manufacturers (trucks, buses, off-road), EV manufacturers, and special vehicle makers. Customers include the Volkswagen Group, BMW Group, MAN Truck & Bus, Volvo Cars, and Jaguar Land Rover. The company distributes through direct enterprise field sales, Tier-1 system integration, and participation in major automotive trade shows and supplier summits. Leoni's distribution advantage is anchored by manufacturing presence in low-cost geographies (Morocco, Egypt, Mexico, Tunisia, Romania, Serbia, Ukraine, Poland) and proximity-located facilities that enable localized supply to global OEM production sites.
Leoni was historically publicly listed (etr:LEO) but delisted in 2023 after a StaRUG-led financial restructuring that reduced debt by approximately €708 million, eliminated existing equity through capital reduction to zero, and brought in Stefan Pierer as strategic investor via a €150 million capital increase. In July 2025, Chinese precision manufacturer Luxshare Precision (Luxshare-ICT) acquired a 50.1% controlling stake for approximately €320 million, integrating Leoni into its global automotive Tier-1 platform and increasing the stake further in April 2026. The company continues to operate under the Leoni brand, with leadership under CEO Klaus Rinnerberger (extended through end-2027) and CFO Andreas Krifka, and is expanding aggressively in Morocco, Egypt, and Mexico to support EV and autonomous vehicle wiring demand.
