About Warrior Met Coal

Warrior is a large scale, low-cost U.S. based producer and exporter of premium hard coking coal (“HCC”), operating highly efficient longwall operations in its underground mines located in Alabama. The HCC that Warrior produces from the Blue Creek coal seam contains very low sulfur and has strong coking properties and is of a similar quality to coal referred to as the benchmark HCC produced in Australia. The premium nature of Warrior’s HCC makes it ideally suited as a base feed coal for steel makers and results in price realizations near the HCC benchmark. Warrior sells all of its met coal production to steel producers in Europe, South America and Asia. For more information about Warrior Met Coal, please visit www.warriormetcoal.com.
