Exhibit 99 News from Arch Coal, Inc. -------------------------------------------------------------------------------- FOR FURTHER INFORMATION: Media Relations - Kim Link (314) 994-2936 Investor Relations - Deck Slone (314) 994-2717 FOR IMMEDIATE RELEASE Arch Coal Discloses Agreement To Sell Triton's Buckskin Mine, Contingent Upon the Acquisition of Vulcan ST. LOUIS (March 8, 2004) - In its 2003 annual report being filed today with the Securities and Exchange Commission, Arch Coal, Inc. (NYSE: ACI) disclosed that it had signed an agreement in late January to sell Triton Coal Company's Buckskin mine to Kiewit Mining Acquisition Company for a purchase price of $82.0 million. The transaction is contingent upon the completion of Arch's acquisition of Vulcan Coal Holdings, which owns all of the equity of Triton Coal Company. On May 29, 2003, Arch Coal signed a definitive agreement to acquire Vulcan Coal Holdings LLC. That transaction is currently under review by the Federal Trade Commission. Triton is the nation's seventh largest coal producer and the operator of the North Rochelle and Buckskin mines in Wyoming's Powder River Basin. The Federal Trade Commission was informed in early December 2003 that Arch was contemplating the sale of the Buckskin mine to Kiewit Mining, and was subsequently notified in late January 2004 that an agreement had been signed. The North Rochelle mine shares a 5.5-mile property line with Arch's existing Black Thunder mine. The potential future integration of the two mines creates tremendous opportunities for cost savings and synergies. Kiewit Mining Acquisition Company is a subsidiary of Peter Kiewit Sons' Inc.'s Kiewit Mining Group, located in Omaha, Neb. St. Louis-based Arch Coal is the nation's second largest coal producer and mines low-sulfur coal exclusively. Through its subsidiary operations in West Virginia, Kentucky, Virginia, Wyoming, Colorado and Utah, Arch provides the fuel for approximately 6 percent of the electricity generated in the United States.
