Siemens acquires Mermec’s core rail business in deal reported near €1.2bn
Siemens acquires Mermec’s core rail business, reported near €1.2bn, boosting its signal and diagnostics portfolio and targeting significant revenue growth over time.
Siemens announced on Thursday that it is buying the core rail-technology business of Italian firm Mermec, strengthening the Munich group’s global signal and diagnostics capabilities. The Siemens acquisition of Mermec covers the company’s train-signal, diagnostic and measurement operations based in Monopoli near Bari. While Siemens said the purchase price is confidential, two people familiar with the transaction told Reuters the sum is about €1.2 billion.
Scope of the assets purchased
The transaction includes Mermec’s measurement trains and its railway signal and diagnostic systems that monitor track and infrastructure condition. Those measurement systems are used to inspect track geometry and assess wear, giving operators data for maintenance and safety planning. The sale does not include Mermec’s signal activities in France, the United Kingdom and Germany, which were previously acquired by Hitachi Rail and are excluded from this deal.
Financial profile and workforce
Mermec’s core business reported around €430 million in revenue with an operating margin (EBITDA) of roughly 17 percent, according to a corporate presentation. The unit employs about 1,700 staff, and roughly three quarters of its sales are generated in Italy where it holds a strong position in long-distance and mainline signalling. Siemens said it will integrate these operations into its existing Mobility division while keeping production and engineering activities in the region.
Reported price and confidentiality
Siemens maintained that the purchase price is confidential; however, Reuters cited two people close to the matter estimating the consideration at near €1.2 billion. The company’s public statement avoided a specific figure but described the acquisition as a strategic move to expand its industrial footprint in Italy and to broaden its diagnostics offering worldwide. Regulatory filings or formal disclosures will ultimately clarify the exact terms once they are required by law.
Projected revenue and cost effects
Siemens Mobility expects the addition of Mermec’s product range to boost rail-related sales by about €400 million in the medium term and up to €500 million over the longer term. The company also forecasts integration savings that should lift operating profit by approximately €15 million within two years of closing. Siemens is positioning the purchase as a way to capture demand from ongoing and planned modernization of Italy’s rail network.
Seller’s rationale and future investments
Mermec’s owner, Vito Pertosa, explained the sale in personal terms, citing his formal retirement, health considerations and his family’s shifting business interests. Pertosa said he wanted a secure future for the company’s employees and intends to use proceeds to back other firms within his Angelo industrial holding, which has activities including aerospace. The move represents a consolidation of core rail assets under a major global supplier while freeing capital for Pertosa’s broader investment strategy.
Market implications and competition
Industry analysts say the acquisition strengthens Siemens’ competitive position in trackside diagnostics and signalling, a market where accurate monitoring and predictive maintenance are increasingly valued. By combining Mermec’s measurement trains and diagnostic tools with Siemens’ existing infrastructure systems, the group expects to offer more integrated solutions to rail operators. The carve-out of certain international signal portfolios means the deal enhances Siemens’ Italian presence without affecting recently restructured operations elsewhere.
The deal will likely face standard regulatory review and operational integration challenges, including harmonising product lines and aligning customer support across markets. Siemens’ ability to realise the stated revenue and cost synergies will depend on execution, roll-out of combined offerings and continued investment in network modernisation projects, particularly in Italy where much of Mermec’s revenue is concentrated.
The acquisition marks a notable consolidation in European rail technology, bringing together Siemens’ global reach and Mermec’s specialist measurement capabilities to meet growing demand for data-driven infrastructure management.
