Martin Marietta Materials Inc. has acquired three quarries plus the remaining 49% interest in an existing joint venture from CEMEX Inc. The purchase price for the assets of the three quarries plus the 49% interest was $65 million. Based on 2008 results without synergies, this equates to a multiple of 6.8 times EBITDA. Estimated mineral reserves are 255 million tons.

The quarry operations are located at Fort Calhoun, Nebraska, Guernsey, Wyoming, and Milford, Utah. Guernsey and Milford are rail-connected quarries while Fort Calhoun ships material via barge on the Missouri River in addition to its local and long-haul truck market in Nebraska. The 49% interest purchased relates to the Granite Canyon, Wyoming, quarry where Martin Marietta is the operating manager. Granite Canyon is a major supplier of railroad ballast serving both the Union Pacific Railroad and Burlington Northern Santa Fe Railway. Aggregate shipments in 2008, including the partial interest only in Granite Canyon, were 3.3 million tons.

“We are pleased to be able to add this set of quarries to our western operations as well as being able to purchase the minority interest at Granite Canyon,” said Stephen P. Zelnak, Jr., chairman & CEO of Martin Marietta. “These operations are a very good fit with our Western business and will enable us to pursue growth via additional rail and water transport possibilities. Financially, we expect the acquired operations to be modestly accretive in 2009 with increased contributions as the economy improves.”

“In addition to enhancing our existing logistical network, these new quarries provide attractive product synergies,” added Ward Nye, president & COO. “Ballast and rip-rap are notable in stimulus and other construction projects critical to the rebuilding of U.S. infrastructure. The sites also strengthen our position as a premier stone supplier to the railroad industry. We will substantially complete the integration of these new operations into our existing business within a matter of days.”
