SunCoke Energy (NYSE:SXC) is a leading independent producer of metallurgical coke and provider of energy solutions for the steel industry. Headquartered in Lisle, Illinois, the company was formed as a spin-off from Sunoco, Inc. in 2005 and has since grown into one of the largest domestic suppliers of coke, serving major steel producers across North America. SunCoke’s operations are strategically located adjacent to its customers’ facilities, creating an integrated supply chain that enhances efficiency and reliability.
The core of SunCoke’s business lies in the manufacture of high-quality metallurgical coke, a critical input in the blast-furnace process used to convert iron ore into steel. In addition to merchant coke sales, the company offers byproduct coke, which is produced as a secondary product and sold through long-term contracts. SunCoke also captures and markets a range of byproduct energy streams—including electricity, steam and natural gas—as well as chemical byproducts such as sulfuric acid, tar and light oils, supporting both industrial and power-generation customers.
SunCoke operates a network of coke manufacturing facilities in key steel-making regions, with plants in Indiana, Ohio and Alabama. Each facility is designed to optimize production capacity and environmental performance, employing advanced emission-control technologies. The company’s logistics organization manages transportation by rail and barge, ensuring timely delivery to domestic and international steel mills. SunCoke also pursues strategic partnerships to expand its geographic reach and product offerings.
Governance and sustainability are central to SunCoke’s corporate strategy. Led by an experienced management team and governed by an independent board of directors, the company emphasizes safety, environmental stewardship and continuous improvement. Investments in energy-efficiency upgrades, greenhouse-gas reduction projects and community engagement initiatives underscore SunCoke’s commitment to responsible operations and long-term value creation for stakeholders.
