The amount of the transaction is 39 billion pesetas (approximately 260 million U.S. dollars). This sale represents 11% of CEMEX´ operations in Spain.

The plant has an installed production capacity of one million metric tons of cement per year. The agreed price also includes the sale of the ready-mix concrete, mortar and aggregates plants in Andalucâa and Extremadura.

This sale allows Valenciana de Cementos to continue being the leader in the Spanish market and to maintain its economies of scale and efficient logistics.

Valenciana de Cementos is CEMEX´ principal international subsidiary, allowing it access to lower costs of capital in order to strengthen the company´s financial structure.
