The story
In December 1992 the group acquired the Piombino steelworks from Ilva.
In 2005 the Russian steel and mining company Severstal became the majority shareholder (approximately 60%) of Lucchini, the remainder being owned by the Lucchini family (30%) and other minor shareholders.
In 2007, the Lucchini family bought back Lucchini RS, the part of the group active in the railway rolling stock business. The two companies are therefore totally independent.
In 2010, Severstal acquired the remaining shares held by the Lucchini family.
