Caverion Germany acquires WISAG Automation Technology and expands building automation capabilities

Caverion Deutschland GmbH is acquiring WISAG Automatisierungstechnik GmbH & Co. KG, or WAT for short. The seller is the WISAG Group. Since 1988, WAT has operated in Germany as a specialist in building automation, providing measurement, control and regulation technology solutions. A total of 168 employees at seven locations plan, install and maintain building automation systems, ranging from building management systems and energy management to 24/7 on-call service. WAT most recently generated annual revenue of around €27 million. The transaction is scheduled to close at the turn of the year, subject to approval by the German Federal Cartel Office.

With this acquisition, Caverion Deutschland is consistently continuing its growth trajectory. Following Schulz Lufttechnik (2025), S&A Schaltanlagenbau (2026) and KEES Klima- und Kältetechnik (2026), WAT is the largest acquisition to date for Caverion Deutschland. Building automation is a strategic growth area for Caverion: Requirements for energy efficiency, decarbonization and data-based building operations are increasing, as is the need to modernize existing buildings.

“Building automation plays a decisive role in determining how efficiently and sustainably a building operates. Ease of use and a strong service team are key factors for customers. With the acquisition of WISAG Automatisierungstechnik, we are gaining a competent team with its own product and solution expertise, as well as many years of experience in the building technology market. We are very pleased to welcome this reinforcement and warmly welcome our new colleagues,” says Manfred Simmet, Managing Director of Caverion Deutschland GmbH.

“Our customers and business partners can continue to rely on their familiar contacts. With Caverion, we have not only found an owner with proven technical expertise, but also a company that will continue to focus on building automation as a strategic growth area over the long term,” says Jörg Friese, Head of WISAG Automatisierungstechnik.

Both parties have agreed not to disclose the purchase price.
