Usiminas board of directors passes resolution dismissing CEO and two other Usiminas executives

Luxembourg, September 26, 2014 – Ternium S.A. (NYSE: TX) announced today that the board of directors of Usinas Siderúrgicas de Minas Gerais S.A. – USIMINAS (“Usiminas”) passed a resolution dismissing the company’s chief executive officer (Diretor-Presidente) and two other executives from their respective positions at the Usiminas board of officers. The board resolution dismissing the officers was passed with a 5 to 5 vote, and the tie was resolved by the chairman of the board through his casting vote.

The dismissal of the officers is part of a controversy that arose within the Usiminas control group with respect to rules applicable to the appointment of senior managers. Ternium believes that the votes cast by the NSSMC Group-appointed members were computed in violation of the shareholders agreement that governs the rights of the members of Usiminas’ control group. The NSSMC Group is comprised by Nippon Steel & Sumitomo Corporation, Mitsubishi Corporation and Metal One Corporation.

Following the dismissal of the officers, the position of CEO of Usiminas will be held, on a temporary basis until a new board of officers is agreed between the T/T Group (composed of Ternium S.A., Siderar S.A.I.C. and Confab Industrial S.A.) and the NSSMC Group, by Romel Erwin de Souza, Usiminas’ current Vice-president of Technology, who was elected with the same votes that decided the dismissal.

Ternium intends to take all reasonable actions to protect its rights and investment in Usiminas.
