UNITED STATES v. CEMEX, S.A.B. de C.V. and RINKER GROUP LIMITED

Proposed Modification of the Modified Final Judgment

Take notice that a Joint Motion to Establish Notice and Comment Procedures and to Modify the Modified Final Judgment, a Memorandum of Plaintiff United States in Support of Joint Motion to Establish Notice and Comment Procedures and to Modify the Modified Final Judgment have been filed, and a proposed Order to Establish Notice and Comment Procedures for the Modification of the Modified Final Judgment has been entered, in the United States District Court for the District of Columbia in United States v. Cemex, S.A.B. de C.V. and Rinker Group Limited, Civil No. 1:07-cv-00640. On April 4, 2007, the United States filed a Complaint (and an Amended Complaint on May 2, 2007) alleging that Cemex, S.A.B. de C.V.'s ("Cemex") proposed acquisition of Rinker Group Limited ("Rinker") would violate Section 7 of the Clayton Act, 15 U.S.C. § 18, by substantially lessening competition in the production and distribution of ready mix concrete in the metropolitan areas of Fort Walton Beach/Panama City/Pensacola, Jacksonville, Orlando, Tampa/St. Petersburg, Fort Myers/Naples, Florida, and the metropolitan areas of Flagstaff and Tucson, Arizona. In addition, the acquisition would have substantially lessened competition in the production and distribution of concrete block in metropolitan Tampa/St. Petersburg and Fort Myers/Naples, Florida. Finally, the acquisition would have substantially lessened competition in the production and distribution of aggregate in metropolitan Tucson, Arizona.

The Modified Final Judgment, entered on November 28, 2007, required Cemex to divest 39 ready mix concrete, concrete block, and aggregate plants that served metropolitan areas in Florida and Arizona, including the Orlando, Florida area. On November 30, 2007, Cemex divested these assets to CRH plc ("CRH"). The current proposed modification would allow Cemex to reacquire Rinker's Kennedy ready mix concrete plant, located at 1406 Atlanta Avenue, Orlando, Florida 32806, which was one of the plants divested to CRH. Cemex's reacquisition of the Kennedy plant is conditioned on CRH's acquisition of Cemex's own plant in Orlando, which is located only one-half mile away from the Kennedy plant.
