U.S.-based Arch Coal is a leading coal producer and marketer, with 96 million tons of coal sold in 2016. We have two distinct but complementary lines of business. We produce high-quality metallurgical coal for sale in the global steel market, and we produce highly cost-competitive thermal coal, primarily in the PRB, for sale into the domestic and international power generation markets. Arch is a well-positioned American coal company with large, modern, low-cost mining complexes and high-quality reserves in strategic U.S. coal supply basins. In total, we represent over 13% of America’s coal supply from our active mining complexes in  West Virginia, Wyoming, Colorado and Illinois.
