[ROME] Siemens said on Thursday (May 14) that it has agreed to buy the core business of Italian rail technology group Mermec, to strengthen its rail portfolio and gain market access to Italy.

The parties agreed not to disclose the transaction’s financial terms, the German ⁠engineering group said. Two people familiar with the transaction said that the deal was worth 1.2 billion euros (S$1.8 billion).

Michael Peter, CEO of Siemens Mobility, said: “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 signalling capabilities.”

The company added that the deal would support the modernisation and digitalisation of the national rail network in Italy.

Siemens’ estimated revenue synergies were worth more than 400 million euros a year in the midterm, and would grow to 500 million euros yearly in the long-term, the German group said in slides for investors.

Mermec, based in the southern Italian town of Monopoli near Bari, is owned by investment holding company Angel Holding, headed by chief executive Vito Pertosa.

He said that he pursued the transaction for health and family reasons, and that it would contribute to the growth of the company and help create new jobs.

In 2025, the group had revenues of more than 430 million euros, 75 per cent coming from Italy, and a core profit margin of 17 per cent, the slides showed.

As part of the deal, Mermec’s employees, which number 1,700 worldwide, as well as all sites and industrial capabilities, will become part of Siemens Mobility. This includes a key site in the town of Matera, set to become an industrial hub for next-generation diagnostics.
