SunCoke Energy, Inc. is a coke and industrial services company that reports two main segments: Domestic Coke and Industrial Services. Its five U.S. cokemaking plants have nameplate capacity of about 3.7 million tons of blast furnace coke per year underpinned largely by long-term, take‑or‑pay contracts with major steelmakers such as Cliffs Steel and U.S. Steel.
The company also operates logistics and slag-handling assets that can handle more than 40 million tons of coal and other bulk materials annually. In 2025 it recorded a $90.1 million impairment tied to its Haverhill I facility following Algoma Steel’s contract breach and decided to close that plant in early 2026. SunCoke reduced legacy coal black lung exposure via a $36.0 million lump‑sum payment, cutting that liability by $45.5 million, leaving a remaining obligation of $12.6 million at year‑end 2025.
SunCoke emphasizes safety and human capital, reporting a 2025 Total Recordable Incident Rate of 0.55 at its coke facilities and terminals, significantly below industry averages, and employs about 2,477 people across six countries. As of June 30, 2025, non‑affiliate equity market value was approximately $721,117,091, with 84,665,509 common shares outstanding as of February 13, 2026.
