Siemens has successfully completed the acquisition of several key businesses of MERMEC Group, an Italian high-tech leader in railway signaling, diagnostics, and measurement technologies. Following receipt of all required approvals, the acquired businesses are now part of Siemens Mobility. The transaction was announced in May 2026.
The acquisition will further strengthen Siemens’ global rail infrastructure portfolio, supporting its long-term strategy and investments in the growing railway market. The integration of MERMEC’s strong presence in Italy’s mainline railway infrastructure with Siemens’ expertise in urban signaling will support the modernization and digitalization of the national rail network in Italy.
Siemens Mobility’s customers will benefit from an expanded service offering that combines Siemens’ asset intelligence and diagnostics capabilities (onboard and depot‑based) with MERMEC’s advanced portfolio of diagnostic vehicles equipped with measurement systems and software for railway infrastructure inspection. The result will be a scalable diagnostics and analytics platform with global reach through Siemens Mobility’s worldwide footprint and established customer base.
The acquisition covers MERMEC’s key businesses in Italian wayside signaling, electrification, telecommunication, diagnostics, and analytics, enabling better predictive and data-driven asset management. It excludes MERMEC’s investments in Angelstar S. r. l., Mont Saint Michel S.A.S. with its subsidiary Compagnie des Signaux S.A.S. and CSEE DE – former MERMEC Deutschland – (Angelo Holding).
With around 1,700 employees, the acquired businesses serve customers in over 70 countries, having generated revenue of approximately 430 million EUR in financial year 2025. MERMEC’s employees, all sites including the Ferrosud site in Matera, and industrial capabilities will become part of Siemens Mobility’s global innovation ecosystem.
