CEMEX, S.A. de C.V (NYSE:CX), one of the largest cement companies in the world, announced today an agreement to sell its aggregates operations in Kentucky and Missouri to Rinker Materials Corporation. The sale price is $42 million plus working capital, and the sale is expected to close on December 28.

With an annual production of 3.2 million short tons, the Kentucky aggregate operations consist of four quarries (Bowling Green North, Bowling Green South, Hartford, and Bardstown), while the Missouri operations consist of one quarry in Columbia.

"Although the Kentucky and Missouri quarries are well run and profitable, they have relatively limited strategic value for CEMEX," said Gilberto Perez, President of CEMEX's U.S. Operations.

The Kentucky and Missouri quarries were acquired by CEMEX in November 2000 as part of its acquisition of Southdown.

CEMEX is a leading global producer and marketer of cement and ready-mix products, with operations concentrated in the world's most dynamic cement markets across four continents. CEMEX combines a deep knowledge of the local markets with its global network and information technology systems to provide world-class products and services to its customers, from individual homebuilders to large industrial contractors.
