We are one of the world's largest coal producers. For the year ended
December 31, 2013, we sold approximately 140 million tons of coal, including
approximately 2.8 million tons of coal we purchased from third parties,
representing roughly 14% of the 2013 U.S. coal supply. We sell substantially all
of our coal to power plants, steel mills and industrial facilities. At
December 31, 2013, we operated, or contracted out the operation of, 22 active
mines located in each of the major coal-producing regions of the United States.
The locations of our mines and access to export facilities enable us to ship
We were organized in Delaware in 1969 as Arch Mineral Corporation. In July
1997, we merged with Ashland Coal, Inc., a subsidiary of Ashland Inc. that was
formed in 1975. As a result of the merger, we became one of the largest
producers of low-sulfur coal in the eastern United States.
