What SG Automotive does

SG Automotive d.o.o. is a Slovenia-based Tier-1/Tier-2 automotive component manufacturer, founded in 1998 as a joint venture between the GRAH family and Alfred Schefenacker. Following a 2010 management buyout, the company operates as a subsidiary of GRAH Automotive Group; in 2022, Slovenian financial investor WSO5 d.o.o. became an additional shareholder. The company manufactures LED lighting modules, wire harnesses, plastic components, and electronic assemblies (PCBA) for automotive OEMs, with additional production of industrial and home appliance electronics.

Its core technology portfolio centers on the globally patented 360 approach™ LED lighting platform, supported by IATF 16949 / ISO 9001 / ISO 14001 / ISO 50001 certifications and APQP/PPAP quality processes. Production is split across two plants: the Slovenske Konjice (Slovenia) headquarters for automotive LED lighting and electronics, and a Batocina (Serbia) facility for wire harnesses and industrial electronics. In-house plastics and tooling are supplied by subsidiary Technoplast d.o.o. in Blejska Dobrava, providing vertical integration from housings and lenses to finished sub-assemblies. A former lighting division, Grah LED Lighting, spun off in 2016 as an autonomous entity commercializing the same LED technology in street, outdoor, office, and yacht lighting markets.

SG Automotive generates revenue through direct B2B supply contracts with major automotive OEMs including Mercedes-Benz, BMW, Audi, Porsche, Volkswagen, Toyota, Ford, Volvo, Renault, Hyundai, Kia, Škoda, Peugeot, Jaguar, and Maserati, as well as Tier-1 suppliers and home appliance/industrial customers such as Bosch, BSH, and Hilti. Sales are executed via dedicated key account managers (Head of Sales plus multiple country-based KAMs) with direct OEM relationships; pricing is quote-based and not publicly disclosed. The company employs 101–250 staff and operates without public market listing.
