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 significantly strengthens Siemens Mobility’s diagnostics and asset intelligence portfolio while further expanding its signaling activities and industrial footprint in Italy. The transaction was announced in May 2026
“Welcoming MERMEC’s employees and businesses to Siemens Mobility marks an important milestone in strengthening our global rail technology portfolio. By combining our complementary capabilities in signaling, diagnostics, and asset intelligence, we are enhancing the value we deliver to customers worldwide while further expanding our industrial footprint in Italy,” said
Michael Peter, President of Siemens Mobility.
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 EUR 430 million in FY25. MERMEC’s employees,
all sites including the Ferrosud site in Matera, and industrial capabilities
will become part of Siemens Mobility’s global innovation ecosystem.
