CEMEX, S.A.B. de C.V. (“CEMEX”) (NYSE: CX), announced today that the subscription issue price of the new Ordinary Participation Certificates (“CPOs”) to be delivered to holders of CEMEX common ordinary shares series “A” and “B” and CPOs as a result of the capital increase approved by CEMEX’s shareholders at the general ordinary shareholders meeting held on April 29, 2010 is of MX$14.2460 per CEMEX CPO. This amount is the weighted average price of all CEMEX CPO transactions on the Mexican Stock Exchange (Bolsa Mexicana de Valores, S.A.B. de C.V.) as of May 27, 2010. The shares will be subscribed for at a price of MX$4.7487 per share, of which MX$0.00277661 will go to our capital stock and the remaining amount as premium for the subscription of capital, and will be deemed fully paid by a capitalization of retained earnings. CEMEX shareholders will not be required to pay any consideration in connection with the issuance of the shares.

Current CEMEX shareholders will receive 1 new CEMEX CPO per 25 CEMEX CPOs held, or, if applicable, 3 new shares per 75 shares currently outstanding, and holders of CEMEX American Depositary Shares (“ADS”) will receive 1 newly issued ADS per 25 ADSs held. There will be no cash distribution under any circumstance, not even for fractions from which no new shares can be issued.

The delivery of the new CPOs or shares, as applicable, will be made starting on June 7, 2010. Only holders of record of CEMEX CPOs or ADSs as of June 1, 2010 will receive new shares as a result of the increase in the capital stock. The new ADSs to be issued will be distributed on or about June 8, 2010. Each ADS represents 10 CPOs.

As a result of all of the above, the conversion rate of CEMEX's 4.875% convertible subordinated notes due 2015 and CEMEX's 10% mandatory convertible obligations due 2019 will be adjusted accordingly.
