CEMEX in Negotiations with CRH plc Relating to Asset Divestitures.

MONTERREY, Mexico -- CEMEX, S.A.B. de C.V. (NYSE: CX) announced today that it is in negotiations with CRH plc, the Ireland-based international building materials group, that may lead to the divestiture of certain CEMEX assets located in the United States and in Europe. The completion of any transaction would be subject to satisfactory due diligence, the approval of the respective Boards of Directors and the granting of the required regulatory approvals (including the U.S. Department of Justice and other antitrust authorities.)

The assets under negotiation include those operations in Florida and Arizona that the U.S. Department of Justice has required CEMEX to divest as a result of the acquisition of Rinker. In addition, CRH is in negotiations to acquire from CEMEX some or all of the following CEMEX assets in the United States: CEMEX's concrete pipe business; the company's materials and concrete products operations in the Pacific Northwest, Utah, Wyoming, Nebraska, New Mexico and El Paso, Texas; the aggregates operations in Kentucky; CEMEX's cement plants in Wampum, Pennsylvania and Fairborn, Ohio; and, its gypsum wallboard distribution business in Florida. In Europe, the assets under negotiation include the San Feliu cement plant in Catalonia, Spain and CEMEX's ready-mix concrete and aggregates assets in Austria and Hungary.

Given the mix of CEMEX and Rinker assets, and the fact that CEMEX's acquisition of Rinker has only recently been completed, detailed combined financial information on a consistent basis is not yet available. Depending on the scale of businesses included in any potential deal, and the outcome of due diligence, the total value of the transactions could range from US$3.5 billion to US$4.5 billion (euro 2.5 billion to euro 3.2 billion).

Citigroup, Merrill Lynch and Morgan Stanley are acting as financial advisors.

EBITDA is defined as operating income plus depreciation and amortization. Free Cash Flow is defined as EBITDA minus net interest expense, maintenance and expansion capital expenditures, change in working capital, taxes paid, and other cash items (net other expenses less proceeds from the disposal of obsolete and/or substantially depleted operating fixed assets that are no longer in operation). Net debt is defined as total debt minus the fair value of cross-currency swaps associated with debt minus cash and cash equivalents. The net debt to EBITDA ratio is calculated by dividing net debt at the end of the quarter by EBITDA for the last twelve months. All of the above items are derived from generally accepted accounting principles in Mexico. EBITDA and Free Cash Flow (as defined above) are presented herein because CEMEX believes that they are widely accepted as financial indicators of CEMEX's ability to internally fund capital expenditures and service or incur debt. EBITDA and Free Cash Flow should not be considered as indicators of CEMEX's financial performance, as alternatives to cash flow, as measures of liquidity or as being comparable to other similarly titled measures of other companies.
