                  Ternium Obtains Full Ownership of Grupo Imsa

    LUXEMBOURG--(BUSINESS WIRE)--July 26, 2007--Ternium S.A. (NYSE:TX)
announced today that, following the settlement of its previously
announced tender offer for shares of Mexico-based steel producer Grupo
Imsa S.A.B. de C.V. and the concurrent redemption of those shares not
tendered during the tender offer, it now owns all of the outstanding
share capital of Grupo Imsa. All of the shares tendered and redeemed
received the same price of US$6.40 per share in cash.

    With the completion of the transactions described above, Ternium
has significantly expanded its business in North America, a region
that now accounts for a majority of its net sales, and has broadened
its presence in Mexico, which is the second largest flat steel market
in the Americas behind the United States. Ternium plans to move
promptly to integrate Grupo Imsa into its industrial and supply-chain
systems.

    To finance the transactions consummated today, partially refinance
existing debt and pay associated taxes and expenses, Ternium and
certain of its Mexican subsidiaries (including Grupo Imsa) are or will
become parties to syndicated term loan facilities in the aggregate
principal amount of up to US$3.8 billion. Ternium will consolidate
Grupo Imsa's balance sheet and results of operations in its
consolidated financial statements from July 26, 2007.
