Siemens Mobility has signed an agreement to acquire several key businesses of MERMEC Group, the Italian rail technology company active in signalling, electrification, diagnostics and measurement technologies.
The acquisition covers MERMEC’s key businesses in Italian wayside signalling, electrification, telecommunications, diagnostics, analytics and worldwide data infrastructure. The businesses included in the transaction employ around 1,700 people, serve customers in more than 70 countries and generated revenue of approximately EUR 430 million in FY25.
The deal 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 MERMEC Deutschland.
The parties have agreed not to disclose the financial terms of the transaction. Closing is subject to customary conditions and is expected by the end of calendar year 2026.
Michael Peter, CEO of Siemens Mobility, said the transaction would combine MERMEC’s technological expertise and market access with Siemens Mobility’s global presence and technology leadership, strengthening the company’s capabilities in diagnostics, asset intelligence and signalling. He added that the acquisition would expand Siemens Mobility’s industrial footprint in Italy and enhance its global diagnostics portfolio.
The acquisition is expected to further strengthen the competitiveness and resilience of Siemens’ global rail infrastructure portfolio, supporting its long-term strategy and investment in the growing railway market.
Siemens Mobility customers will benefit from an expanded service offering combining Siemens’ asset intelligence and diagnostics capabilities, including onboard and depot-based systems, with MERMEC’s portfolio of diagnostic vehicles equipped with measurement systems and software for railway infrastructure inspection.
According to Siemens Mobility, the result will be a scalable diagnostics and analytics platform with global reach through the company’s worldwide footprint and established customer base.
Why it Matters
The acquisition points to the growing importance of diagnostics, measurement systems and asset intelligence in the global rail supply chain. As rail networks become more data-driven, the ability to inspect infrastructure, monitor asset condition and support maintenance planning is becoming as important as traditional signalling and control systems.
For railway operators and infrastructure owners, including those in African markets, supplier capability in these areas will increasingly influence how networks are maintained, modernised and made more reliable. Siemens Mobility’s acquisition of key MERMEC businesses brings signalling, diagnostics, analytics and infrastructure inspection into a broader global portfolio, making the transaction relevant beyond Italy and the immediate corporate deal.
