Siemens Mobility on May 14 reported signing an agreement to acquire “several key businesses” of MERMEC Group, an Italian supplier of railway signaling, electrification, diagnostics, and measurement technologies. The transaction, it said, “will significantly strengthen Siemens’ global rail portfolio, with a particular focus on diagnostics and measurement technologies, while further expanding its signaling activities, industrial footprint, and market access in Italy.”
According to Siemens, the parties have agreed not to disclose the financial terms of the transaction, the closing of which “is subject to customary conditions” and is expected by the end of calendar-year 2026.
The acquisition covers MERMEC’s key businesses in Italian wayside signaling, electrification, telecommunication, diagnostics, analytics, and worldwide data infrastructure, while excluding MERMEC’s investments in Angelstar S.r.l., Mont Saint Michel S.A.S. with its subsidiary Compagnie des Signaux S.A.S. and MERMEC Deutschland. “With around 1,700 employees, these key businesses serve customers in over 70 countries, having generated revenue of approximately EUR 430 million in FY25,” according to Siemens.
“The integration of Siemens’ expertise in urban signaling with MERMEC’s strong presence in Italy’s main line railway infrastructure will support the modernization and digitalization of the national rail network in Italy,” reported Siemens, which noted that its 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, it said, “will be a scalable diagnostics and analytics platform with global reach through Siemens Mobility’s worldwide footprint and established customer base.”
“MERMEC’s employees, all sites, and industrial capabilities will become part of Siemens Mobility’s global innovation ecosystem, which includes the key strategic asset of the Ferrosud site in Matera,” Siemens reported. “Siemens expects to achieve meaningful synergies, especially from cross-selling and from expanding the integrated portfolio. The transaction is expected to be EPS (pre-PPA) accretive by year two post-closing.”
Founded in 1970 and headquartered in Monopoli, Italy, MERMEC Group is described as an “Italian provider of railway signaling systems for main line rail networks, digital diagnostics technologies for railway applications, and high-precision measurement trains.” The group operates in the railway sector across signaling, electrification, diagnostics, digital asset analytics platforms, and advanced inspection technologies.
“By combining MERMEC’s technological expertise and market access with Siemens Mobility’s global presence and technology leadership, we are strengthening our capabilities in diagnostics, asset-intelligence and signaling capabilities,” Siemens Mobility CEO Michael Peter said. “This step expands our industrial footprint in Italy within our world-leading signaling business and significantly enhances our global diagnostics portfolio.”
“Formally, I have been retired for nine months; at present, my health is not at its best, and my children are pursuing their own independent paths with their companies,” said Vito Pertosa, President of Angelo Holding. “For this reason, I sought a very solid group in the sector, in order to guarantee a secure future for my valued colleagues, who have contributed to making MERMEC the company it is today, wherever they may be. Becoming part of Siemens will offer them a global environment, strongly focused on innovation and sustainable growth. The transaction will help me invest in the other companies within my industrial holding, as well as contribute to the growth of businesses in Southern Italy that need to develop and create new high-quality employment.”
