What KOSTAL Group does

KOSTAL Group is a German family-owned automotive electronics supplier, founded in 1912 in Lüdenscheid and now led by the fourth generation of the Kostal family. The group operates 64 locations across 22 countries with approximately 19,900 employees and reported preliminary 2025 revenue of approximately €3.5 billion. It is organized into seven divisions covering automotive electrical systems, electro-mobility power electronics, contact systems, industrial electronics, solar electric products, SOMA, and EV charging infrastructure and software under the Compleo and vaylens brands. The group invests more than €200 million annually in R&D across hardware, embedded software, and cybersecurity (ISO/SAE 21434, ISO 26262).

Core products include steering column modules, human-machine interfaces, driver assistance cameras, on-board chargers (OBC), DC-DC converters, contact systems, solar electronics, industrial automation components, EV charging stations (Compleo), and charge point management software (vaylens). Technology stack centers on embedded automotive electronics with functional-safety and automotive-cybersecurity certifications (IATF 16949, ISO 9001, ISO 26262, ISO/SAE 21434), complemented by a software layer for fleet and depot charging management. R&D exceeds €200 million annually.

The business model is predominantly Tier-1 B2B supply to global OEMs, anchored by Volkswagen Group, General Motors, and Mercedes-Benz on multi-year platform contracts. A second revenue stream is hardware-plus-software EV charging infrastructure (Compleo + vaylens), combining unit sales with subscription software. A third channel distributes solar electric products directly. Recent strategic moves include the 2023 acquisition of Compleo, the 2024 launch of the vaylens software brand, the 2024 Phase 3 expansion in North Macedonia, the 2025 spin-off of KOSTAL Electro Mobility, and a 2025 €150 million IFC credit facility supporting further expansion including Ukraine operations. A 140-job reduction at Abbeyfeale, Ireland reflects OBC production transfer to a lower-cost location.
