CEMEX ANNOUNCES EXPIRATION AND RESULTS OF DEBT EXCHANGE

MONTERREY, MEXICO, SEPTEMBER 10, 2012 – CEMEX, S.A.B. de C.V. (“CEMEX”) (NYSE: CX) announced today that, further to its previous announcement on August 21, 2012, the revised acceptance deadline for its debt exchange offer has now been reached and the exchange condition has, therefore, been amended to 91% or more of existing exposures under the Financing Agreement dated as of August 14, 2009, as amended.

As of today’s date, acceptance notices have been received from participating creditors representing approximately 92.6% of existing exposures. CEMEX intends to issue U.S.$500 million in aggregate principal amount of its new 9.5% senior secured notes due 2018 to participating creditors wishing to exchange their existing exposures for such notes.  As the new notes were oversubscribed, it is anticipated that participating creditors who elected to receive new notes after the early bird expiration date of July 19, 2012, will be allocated approximately 54% of the principal amount of new notes they elected to receive, with the balance of their exposures allocated to new loans or new private placement notes, as applicable.

Given the above, CEMEX has achieved the requisite thresholds to the amendment consents and exchange transaction, subject to execution of final documentation and satisfaction of customary conditions precedent. CEMEX expects the transactions to become effective in the following weeks.

The securities to be offered have not been and will not be registered under the Securities Act and may not be offered or sold in the United States absent an applicable exemption from registration requirements. This announcement does not constitute an offer to sell or the solicitation of an offer to buy securities, nor shall there be any sale of securities, in any jurisdiction in which such an offer, solicitation or sale would be unlawful.
