What Eberspächer does

Eberspächer is a family-owned German Tier 1 automotive systems developer and supplier headquartered in Esslingen am Neckar, founded in 1865 and controlled by the Peters family with Martin Peters as Managing Shareholder and Jörg Steins as CEO. The company operates three divisions: Exhaust Technology (branded Purem by Eberspächer), which produces catalytic converters, particulate filters, SCR systems, and complete exhaust assemblies for passenger cars, commercial vehicles, and fuel cell applications; Climate Control Systems, which spans PTC electric heaters from 12V to 800V for EV battery conditioning and cabin heating, fuel-operated heaters (Hydronic, Airtronic), bus climate platforms (AC138 EVO with CO2 refrigerant, AC135 family), truck parking AC (Cooltronic), and recreational vehicle products (Breezonic, E-Boiler); and Automotive Controls, supplying electronic control units, DC/DC converters, and battery management systems. Revenue is generated through direct engineering-driven sales to global automotive OEMs across approximately 40 production sites in more than 30 countries, with FY2025 consolidated revenue of €4,979.8 million and headcount of 10,374.

The company's technology backbone includes proprietary Positive Temperature Coefficient (PTC) heating with inherent overheat safety, patented heat pump architecture in the AC138 EVO, the Hydro Control System for waste heat recovery (reducing electrical energy consumption by up to 23% in buses), and the e-connected cloud platform providing fleet-wide predictive maintenance and over-the-air updates. Recent strategic moves include partnerships with Topsoe for hydrogen electrolyzer pressure vessels and a joint venture with Zeliox for off-highway energy storage, alongside product launches targeting 800-volt EV architectures, sustainable steel supply chains via Outokumpu Circle Green, and expansion into Direct Air Capture technology.

Eberspächer sells primarily through direct OEM relationships with engineering-led development cycles typical of automotive Tier 1 suppliers, supplemented by a dealer network for aftermarket parking heaters and recreational vehicle products. Revenue model is hardware-driven with project-based multi-year platform commitments, and the 2025 revenue mix shows approximately 50% pass-through revenue (monoliths) versus €2,531.3 million in adjusted net revenue. Customer concentration among unnamed leading global OEMs is typical for the segment, balanced across passenger car, commercial vehicle, bus, and off-highway end markets across Europe, North America, South America, and Asia-Pacific.
