On 14 May 2026, Siemens Mobility has signed an agreement to acquire several key businesses of MERMEC Group, an Italian high-tech leader in railway signaling, electrification, diagnostics, and measurement technologies. The parties have agreed not to disclose the financial terms of the transaction. Closing of the transaction is subject to customary conditions and is expected by the end of calendar year 2026.
“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. 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,” said Vito Pertosa, President of Angelo Holding.
The acquisition will further strengthen the competitiveness and resilience of Siemens’ global rail infrastructure portfolio, supporting its long-term strategy and investments in the growing railway market. The integration of Siemens’ expertise in urban signaling with MERMEC’s strong presence in Italy’s mainline railway infrastructure will support the modernization and digitalization of the national rail network in Italy.
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 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, MERMEC Group is a leading Italian provider of railway signaling systems for mainline 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.
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 430 million EUR in FY25.
