Siemens Mobility gets his hands on some of the most strategic activities of the Mermec Group, a Puglia-based company founded in 1970 and grown to become a reference in high-tech applied to signaling, electrification, diagnostics and measurement technologies for the railway sector. agreement signed by the German group concerns, in particular, the organisers' activities railway diagnostics, data analytics, global data infrastructure, electrification, telecommunications, and railway signaling. A significant industrial footprint, it includes approximately 1.700 employees, customers in over 70 countries, and revenues of approximately €430 million in fiscal 2025.
The financial terms of the deal were not disclosed but according to rumours, the the deal is said to be worth around $1 billion. The closing remains subject to the usual conditions envisaged for operations of this type and is expected by the end of 2026.
Diagnostics, data, and signaling: why the asset is so desirable
For Siemens Mobility, the acquisition represents a long-term industrial moveThe group aims to strengthen your portfolio globally in railway infrastructure, with a particular focus on diagnostic and measurement technologies, two areas that are increasingly central to the modernization of networks.
The integration of Siemens' experience in urban signaling and Mermec's strong presence in Italy's major railway infrastructures should support the digitalization of the national network. The goal is to build a broader offering, combining asset intelligence, on-board, trackside, and depot diagnostics, with Mermec's advanced diagnostic vehicles, equipped with measurement systems and software for infrastructure inspection.
The expected result is a Scalable diagnostics and analytics platform with global ambitions, supported by both Siemens Mobility's international network and Mermec's established customer base. Siemens also expects significant synergies, especially through cross-selling and the expansion of the integrated portfolio. The transaction is expected to have a positive impact on Siemens' earnings per share, on a pre-PPA basis, within the second year from closing.
Matera industrial hub, Monopoli remains in the game
One of the most industrially relevant steps concerns the fate of Mermec's sites and production capacitiesThe employees, plants and industrial skills included in the scope of the agreement will join Siemens Mobility's global innovation ecosystemAmong the assets involved, the Ferrosud site in Matera stands out, designated a strategic hub and destined to become an industrial hub for next-generation railway diagnostics.
The transaction therefore strengthens Siemens Mobility's industrial presence in Italy, particularly in railway signaling, a sector in which the German group claims global leadership. At the same time, Angelo Holding does not leave the gameMermec's investments in Angelstar, Mont Saint Michel with its subsidiary Compagnie des Signaux, and Mermec Deutschland remain outside the agreement.
These activities will flow into a new reality, Angel Signaling, focused on railway signaling. The company will employ approximately 800 people and have already received orders worth approximately €2 billion. Upon completion of the transaction, Angelo Holding will retain a total of approximately 1.500 employees.
Siemens' words and Pertosa's choice
"By combining Mermec's technological expertise and market access with Siemens Mobility's global presence and technological leadership, we will strengthen our capabilities in diagnostics, asset intelligence, and signaling. This step expands our industrial presence in Italy, within our signaling business, in which we are a world leader, and significantly enhances our global diagnostics portfolio," he stated. Michael Peter, CEO of Siemens Mobility.
Behind the decision to sell a central part of Mermec's industrial history there is also a Personal and business evaluation of Vito Pertosa, president of Angelo Holding. “I have been formally retired for nine months. At the moment, my health is not the best and my children are pursuing their own entrepreneurial paths independently. For this reason, I was looking for a particularly solid partner in the sector"To ensure a secure future for my talented employees, who have helped make Mermec the company it is today, wherever they are located. Joining Siemens will give them access to a global organization with a particularly strong focus on innovation and sustainable growth," said Pertosa.
The founder of the Apulian holding company then linked the sale to a new investment phase"This operation will allow me to invest in the other companies in my industrial holding company, as well as contribute to the development of businesses in Southern Italy that need to grow and generate new, qualified jobs."
