About LACROIX
LACROIX GROUP is a French, publicly listed family-owned technology and industrial group with an international footprint, specialized in the development and manufacturing of electronic equipment as well as reliable, secure Industrial IoT solutions. The group is organized into two core areas: the Electronics activity, a leading European EMS provider (Electronics Manufacturing Services) that supports customers from PCB assembly through to Box Build, and the Environment activity with connected solutions for water and energy networks, HVAC and Smart Lighting. Electronic equipment is manufactured for the Automotive, Industrial, Home & Building Automation (HBAS), Avionics/Defense and Healthcare sectors. The production sites in Beaupréau-en-Mauges (France), Willich near Düsseldorf (Germany) and Kwidzyn (Polen) cover everything from prototyping to highly automated high-volume production, complemented by sites such as Zriba (Tunisia) and LACROIX SAE GmbH & Co. KG in Cologne for telemetry and SCADA/control technology. With revenue of €445 million (2025) and 2,850 employees, the group pursues a positive-impact strategy with life-cycle-assessment-based Eco-Design development (PEF method) and cybersecurity according to Security-by-Design, the Cyber Resilience Act and NIS2.
