Salini Impregilo

What Salini Impregilo does

Webuild S.p.A. (formerly Salini Impregilo) is a privately held Italian infrastructure construction group founded in 1900, headquartered in Rome, and operating across 5 continents and 110 countries. The group traces its modern form to the 2014 merger of Salini and Impregilo, was rebranded to the Webuild identity in 2021, and remains under the direction and coordination of parent Salini Costruttori S.p.A. It delivers large-scale civil engineering works organized into four business areas: Sustainable Mobility (metro systems, railways, highways, bridges, ports), Clean Hydro-Energy (dams and hydroelectric plants), Green Buildings (hospitals, airports, stadiums, and corporate headquarters), and Clean Water (treatment plants, desalination, water management). Core technical capabilities include tunnel boring machine (TBM) operations for metro and rail tunnels, large dam and hydroelectric plant construction, and complex maritime infrastructure. Execution is carried out through wholly-owned subsidiaries including Lane (United States), Clough (Australia), and Fisia Italimpianti (industrial water treatment and desalination).

The revenue model is based on multi-year, contract-based infrastructure construction awarded primarily through competitive public tendering with government and public sector clients. Revenue is recognized over project duration with milestone-based payments, and individual contract values range from hundreds of millions to billions of euros (e.g., €803 million for the Genoa Subportual Tunnel). Customers are sovereign or quasi-sovereign entities including the Italian, Australian, Ethiopian, Tajik, and U.S. governments, as well as selected healthcare institutions (Policlinico Gemelli) and corporates (Eni). Go-to-market is enterprise field sales, executed by dedicated business development and proposal teams pursuing tenders across the group's global footprint.

In 2025, the company exceeded its published guidance with revenues above €12.5 billion (+15% year-over-year), EBITDA above €1.1 billion (+18% year-over-year), and a net cash position above €700 million at 2.6x financial leverage, completing the 2023-2025 strategic plan with results above targets. The group is currently executing flagship projects including Snowy 2.0 (Australia), Rogun Dam (Tajikistan), the Grand Ethiopian Renaissance Dam (Ethiopia), Terzo Valico dei Giovi, Rome Metro Line C, Milan Metro M4, and the New Genoa Breakwater.
