Gruppo Lucchini was the third largest Italian steel group after Gruppo Riva and Techint, with a 2005 production of 3.5 million tonnes.

In 2005 the Russian steel and mining company Severstal became the majority shareholder (approx 60%) of Lucchini, the remainder being owned by Lucchini Family (30%) and other minor shareholders.

In 2007, the Lucchini family bought back Lucchini RS, the part of Lucchini Group active in the railway rolling stock business.

The two companies are therefore totally independent.

In 2010, Severstal acquired all the shares of Lucchini Group from the Lucchini family and became the only shareholder of the company.
