What Arnold does

Arnold AG is a Swiss network construction company founded in 1947 and headquartered in Wangen an der Aare. It provides construction, maintenance, and 24/7 emergency services across four infrastructure verticals: Energy (low, medium, high, and extra-high voltage networks, transformer stations), Telecommunications (fiber optic, copper, coaxial installation), Mobility (rail electrification, catenary, tunnel radio, road signaling), and Water (hydrant systems, pipeline construction). The company is registered and operates exclusively in Switzerland, serving energy utilities, telecom carriers, public authorities (including ASTRA, Rhätische Bahn, and Swiss Federal Railways), and industrial clients on a project-based, direct B2B engagement model with negotiated multi-year contracts.

Technically, Arnold AG operates as a platform-plus-subsidiaries group: Arnold AG is the parent, with seven wholly-owned acquired subsidiaries (Baumeler Leitungsbau AG, Curea Elektro AG, Duvoisin-Groux Gruppe, Hinni AG, Arpe AG, Cabcon AG, and elbatech AG, plus the 2025-formed BKW Rail AG) extending domain capabilities in electromechanical work, fiber optics, rail technology, water/hydrant technology, and the proprietary LORNO IT-based water leak monitoring system, as well as the ELKA tunnel radio radiating cable system. The internal Arnold Academy provides training and continuing education for network electricians, and Green Energy Solutions is a sub-brand targeting large-scale renewable projects (photovoltaic, wind, battery storage, ZEV collective self-consumption systems).

Arnold has been majority-owned by BKW FMB Energie AG (BKW) since January 1, 2006, and operates within BKW's Infra Services division. Revenue is generated entirely through professional services contracts and project-based engagements; the company first exceeded CHF 100 million in revenue in 2012, with the Arnold Group's subsidiaries contributing roughly 60% of revenue and Arnold AG 40%. The Arnold Group employed approximately 1,000 people across more than 23 sites at the time of the available sources, making it the largest network construction company in Switzerland's energy sector, with no disclosed venture capital or public-market exposure.
