SunCoke Energy is the largest independent coke producer in the Americas, operating cokemaking facilities across the United States and Brazil that convert metallurgical coal into high-quality coke through thermal processing in refractory ovens. The company generates revenue primarily from long-term, take-or-pay blast furnace coke supply agreements with integrated steelmakers, supplemented by spot market coke sales, industrial services (including material handling, logistics, slag processing, and mill services), and steam and electricity sales from its operations. The business model depends on durable contractual relationships with steel producers, though it faces exposure to regulatory compliance costs, commodity price fluctuations, environmental regulations, alternative steelmaking technologies, and cyclical demand tied to global steel industry conditions.
