CEMEX, S.A. de C.V. (NYSE: CX) announced today that it has divested its 11.92% interest in Cementos Bio Bio, S.A. a cement company in Chile for approximately US$65 million or an implied enterprise value to EBITDA of nine times. The proceeds from the sale will be applied towards debt reduction and the extraordinary gains from this transaction will be reflected in net income. CEMEX acquired this holding for US$34 million in June 1999.

Rodrigo Treviño, Chief Financial Officer, said: "This transaction is consistent with our objective to take all the necessary actions to deliver on our de-levering commitment. As such, we intend to apply as much of our free cash flow from operations and asset disposals as needed towards debt reduction in order to achieve our target of 2.7 times net debt to EBITDA by the end of the year or sooner. The disposal of this non-operating asset will not hinder our future growth and it will not have an impact in our full year consolidated revenues or EBITDA."
