Walter Energy is a publicly owned and traded (NYSE:WLT) producer of coal, coke, and natural gas. Our headquarters are located in Birmingham, Alabama. We are a leading producer and exporter of metallurgical coal for the global steel industry from underground and surface mines located in the Unites States, Canada, and the United Kingdom. We also produce thermal and industrial bituminous coal, anthracite, coke and related products, as well as coal bed methane gas (natural gas). We are a key raw materials supplier to global industries such as steel-makers and foundries. Most of our revenue comes from coal used for steel making rather than for electricity generation. Our coal is converted to coke by baking the coal in ovens in the absence of air. The resulting coke is used in the production of hot metal in a blast furnace. The coke adds heat to the process, adds carbon – the basic building block of steel, and provides permeability that allows for the necessary flow of gases through the charge of material.
