Webuild

The company was founded as Impregilo in 1959 and expanded following a merger with Cogefar-Impresit S.p.A., Girola S.p.A. and Lodigiani S.p.A. in 1990.[4]

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.[5]

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.[6]
