CEMEX, S.A.B. de C.V. (NYSE: CX) announced today that the underwriters of its previously announced global offering have notified it that they intend to exercise their over-allotment options in full and will purchase an additional 195,000,000 Ordinary Participation Certificates (CPOs). Of the total, 146,250,000 CPOs will be purchased in the form of American Depositary Shares (ADSs), with each ADS comprised of 10 CPOs, for resale in the United States and elsewhere outside of Mexico, and 48,750,000 CPOs will be purchased for resale in Mexico.

The additional CPOs will be sold at the same public offering prices as the global public offering of US$12.50 per ADS and MXP16.65 per CPO.

The estimated aggregate net proceeds from the global offering, including proceeds from the exercise of the over-allotment options, are expected to be approximately US$ 1.782 billion.
