SunCoke Energy, Inc. reported upcoming leadership changes. Director Michael W. Lewis, age 76, plans to retire from the Board effective at the Company’s annual meeting of stockholders in May 2026 to focus on personal commitments. He has served on the Board since 2020 and was a member of both the Audit Committee and the Governance Committee. The Company stated that his decision does not stem from any disagreement over operations, policies, practices, or the Company’s general direction.
SunCoke also announced that, effective March 13, 2026, when Shantanu Agrawal assumes the role of Senior Vice President and Chief Financial Officer, Karl A. Zabiello, currently Vice President and Controller, will become the Company’s principal accounting officer.
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.
SunCoke Energy, Inc. reported a 2025 net loss attributable to SXC of $44.2 million, or $0.52 per diluted share, compared with net income of $95.9 million in 2024. The loss was largely driven by $109.3 million of one-time items, including a $90.3 million non-cash impairment tied to the closure of the Haverhill I facility, as well as Phoenix Global-related restructuring and site closure costs.
Full-year 2025 consolidated Adjusted EBITDA was $219.2 million, down from $272.8 million in 2024, as weaker Domestic Coke pricing and volumes, lower Granite City contract economics and the Algoma contract breach outweighed gains from the Phoenix Global acquisition. Operating cash flow was $109.1 million, and SunCoke completed the Phoenix Global acquisition while maintaining a $0.48 per-share annual dividend.
For 2026, SunCoke expects consolidated Adjusted EBITDA between $230 million and $250 million, consolidated net income between $25 million and $43 million, operating cash flow of $230 million to $250 million, and capital expenditures of $90 million to $100 million. Domestic coke sales are guided to about 3.4 million tons with higher margins on a smaller, optimized fleet, while Industrial Services Adjusted EBITDA is projected to rise to $90 million–$100 million with a full year of Phoenix Global and improved terminal volumes.
SunCoke Energy, Inc. entered into a material definitive agreement with United States Steel Corporation to extend their existing metallurgical coke supply agreement for an additional twelve months, covering the period from January 1, 2026 through December 31, 2026. During this 2026 contract period, SunCoke will produce and deliver approximately 590,000 tons of metallurgical coke to U.S. Steel from its Granite City, Illinois cokemaking facility. The extension also maintains SunCoke’s current minimum steam supply obligation under the relationship. The company issued a press release about this extension, which is included as an exhibit.
SunCoke Energy, Inc. reported a planned chief financial officer transition. On January 15, 2026, the company announced that Senior Vice President and CFO Mark W. Marinko will retire effective March 13, 2026, and that Shantanu Agrawal, currently Vice President, Finance and Treasurer, will succeed him as Senior Vice President and CFO.
Agrawal, age 39, joined SunCoke in 2014 and has led key finance and treasury functions such as budgeting, forecasting, financial analysis, cash management, investor relations and procurement. In his new role he will receive an annual base salary of $450,000 and be eligible for an annual non‑equity incentive target equal to 75% of base salary, along with long‑term incentive awards determined by the Board’s Compensation Committee and participation in the company’s existing executive severance and benefit plans. The company states he has no disclosable related‑party transactions or family relationships with directors or executive officers.
