Ternium to Acquire Additional Shares in Usiminas

Luxembourg, October 2, 2014 –Ternium S.A. (NYSE: TX) announced today that it has entered into a definitive purchase agreement with Caixa de Previdência dos Funcionários do Banco do Brasil – PREVI for the acquisition of 51.4 million ordinary shares of Usinas Siderúrgicas de Minas Gerais S.A. – USIMINAS (“Usiminas”) for a total amount of BRL 616.7 million (approximately USD 248.6 million). The price of BRL12 per share (approximately USD4.84) represents a premium of approximately 42% to Usiminas’ ordinary share last-six-months average U.S. dollar price.
