## History

The company was founded as Impregilo in 1960 and expanded following a merger with Cogefar-Impresit S.p.A., Girola S.p.A. and Lodigiani S.p.A. in 1994.
Impregilo established a business relationship with Fisia in 1998, and acquired Todini in 2010.
In 2011 Salini, privately held, began its acquisition of Impregilo with an initial purchase of shares, reaching 25% the following year. The acquisition set a precedent in Italy because it was the first proxy fight for control of a company to occur in the country. Despite the opposition it faced from a group of investors, Salini managed to convince enough shareholders at an assembly in July 2012 to approve its proposal to replace Impregilo’s board of directors with its own list of candidates. Once in place, these new members of the board approved Salini’s offer to buy the rest of Impregilo. Pietro Salini became chief executive. A few months later, the board approved Salini’s plan.
In 2013, Salini launched a tender offer to buy the remaining ordinary shares in Impregilo. In January 2014 the transaction was completed forming Salini Impregilo.
In 2016, it bought Lane Industries, based in Connecticut and, in 2019, it announced the acquisition of a majority stake in Cossi Costruzioni.
In May 2020, the company was rebranded as Webuild. In November 2020, Webuild acquired a 65% shareholding in Astaldi.
In November 2022, Webuild announced that, subject to due diligence, it would acquire the Australian based company Clough Group.
