• Negotiations Regarding Other Assets Terminated

CEMEX, S.A.B. de C.V. (NYSE: CX) announced today that it has completed the sale of its operations in Arizona and Florida, as required by the U.S. Department of Justice in association with the Rinker Group Limited acquisition, to CRH plc, the Ireland-based international building materials group.

CEMEX acquired Rinker in July 2007. As a condition of U.S. regulatory approval, the U.S. Department of Justice required CEMEX to sell 39 ready-mix concrete and aggregate facilities in Arizona and Florida. The value of the transaction is approximately US$250 million.

CEMEX will use the proceeds from the sale of these assets to reduce debt.

The Florida operations being divested comprise 26 ready-mix concrete plants and 6 block plants. The ready-mix concrete business operates in five market areas - Tampa, Southwest Florida, Orlando, Jacksonville and the Florida Panhandle - while the block business operates primarily in the Tampa/St. Petersburg and Fort Myers/Naples areas. In Arizona, the operations comprise 2 quarries and 5 ready-mix concrete locations, principally in the Tucson area.

CEMEX and CRH terminated discussions relating to the potential sale of additional operations due to disagreement over the value of the assets.

CEMEX announced on November 13, 2007, that it is in negotiations with Ready Mix USA, a private ready-mix concrete company with operations in the Southeastern United States, to expand the scope of their ready-mix joint venture formed in July 2005.

CEMEX intends to contribute assets valued at approximately $150 million to the joint venture and intends to sell additional assets to the joint venture for approximately $227 million in cash. As part of the transaction, Ready Mix USA intends to make a $150 million cash contribution to the joint venture. Ready Mix USA will manage all the newly acquired assets. Following the transaction, the joint venture will continue to be owned 50.01% by Ready Mix USA and 49.99% by CEMEX.
