Siemens Mobility to acquire core businesses of rail-tech group MERMEC

On 14 May 2026 Siemens Mobility agreed to acquire the core businesses of Italy's MERMEC group: wayside signalling in Italy, electrification, telecommunications and the worldwide diagnostics and data-analytics business built around measurement trains. These units have about 1,700 employees, supply customers in more than 70 countries and generated roughly EUR 430 million in revenue in 2025; seller Angelo Holding keeps AngelStar, Compagnie des Signaux and MERMEC Deutschland, which will continue as Angel Signaling (about 800 employees, order backlog of roughly EUR 2 billion). The parties are not disclosing financial terms, completion is expected at the end of 2026, and Angelo Holding president Vito Pertosa cites his retirement and health as reasons for the sale (LOK Report, 14 May 2026). Update (20.10.2026): On 20 Oct 2026 the European Commission cleared Siemens Mobility Holding's acquisition of sole control of MerMec without competition concerns (case M.12478; LOK Report).
