On August 23, 2005, the Techint group bought 99.3% of Mexican Hylsamex for US $2.2 billion. In press release, Techint stated that the Mexican steel manufacturer, and its previous steel manufacturers Siderar (Argentina) and Sidor (Venezuela) would be under a new subsidiary called Ternium, headquartered in Luxembourg. On April 30, 2007, Ternium took control of Grupo IMSA, a major player in the Mexican steel industry. Venezuela nationalized Sidor in 2008, following a series of industrial disputes over the previous year. Compensation of around US$1.97 billion was agreed for the nationalisation of Ternium's 60% stake in Sidor, with the former keeping a 10% stake in the company, but frictions emerged with the Kirchner administration in Argentina over their reported refusal to raise objections to the nationalization with President Chávez. In 2016 the Techint Group entered the mining industry through the Tenova's acquisition of several companies operating in this field. Today, the Techint Group had a workforce of 51,200 permanent employees. See history of Techint Group since 1945.
