Recent Developments

Effective February 3, 2011, the Argentine Secretary of Commerce issued Resolution 14/2011, which requires that prices for steel products sold in Argentina (including products sold by Ternium’s subsidiary Siderar) be limited to those in effect on January 21, 2011, and that sales of steel products be invoiced in Argentine pesos. The government has not indicated the duration of these measures. Siderar believes that these measures do not have factual or legal bases, and intends to challenge them through appropriate proceedings, including court action if necessary. Ternium believes that the impact of these measures on its business and results of operations cannot be reasonably estimated at this time.
