CEMEX, S.A. de C.V. (NYSE: CX) announced today the pricing of a non-dilutive equity offering, in which a Mexican trust created to sell the ADSs in the offering, has agreed to sell 27 million ADSs in an underwritten public offering. Citigroup Global Markets Inc. and J.P. Morgan Securities Inc. acted as global coordinators for the offering.

The 27 million ADSs are being offered in the form of both ADSs and CPOs, comprised of 19,986,583 ADSs and 70,134,170 CPOs. One ADS represents ten CPOs. The ADSs are being offered to the public at a price of US$49.50 per ADS, and the CPOs are being offered to the public at a price of MXP53.89 per CPO. The aggregate proceeds of the offering are expected to be approximately US$1.3 billion, after underwriting discounts and commissions. This transaction will not increase the number of shares outstanding and thus will not dilute existing shareholders.

The underwriters have an option to purchase up to an additional 2,956,757 ADSs and 10,365,830 CPOs, respectively, to cover any over-allotments.

A shelf Registration Statement relating to these securities has been filed with the Securities and Exchange Commission and is effective. This announcement shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

The offering is made solely by prospectus. Copies of the prospectus supplement and prospectus may be obtained from the Prospectus departments of Citigroup Global Markets Inc. or J.P. Morgan Securities Inc. at the following addresses:
