SunCoke Energy, Inc. 10-Q Summary: Q3 2025

Business Context and Reporting Period

This Quarterly Report on Form 10-Q covers the period ended September 30, 2025. SunCoke Energy, Inc. is the largest independent producer of high-quality coke in the Americas. The reporting period reflects a significant strategic shift following the acquisition of Flame Aggregator, LLC ("Phoenix Global") on August 1, 2025, for $295.8 million. Consequently, the Company has restructured its reportable segments from three to two: Domestic Coke and Industrial Services (which now includes the former Logistics segment and Phoenix Global operations).

Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Decline: Consolidated revenue decreased 0.6% in Q3 and 6.4% YTD compared to 2024. This was driven by lower pricing in the Domestic Coke segment (due to the mix of contracted vs. non-contracted sales and pass-through of lower coal prices) and lower volumes caused by unfavorable coal-to-coke yields.
• Profitability Pressure: Operating income dropped significantly to $13.4M in Q3 (from $47.2M) and $53.4M YTD (from $116.4M). Net income attributable to SunCoke fell 27.7% in Q3 and 42.7% YTD.
• SG&A Increase: Selling, general, and administrative expenses rose to $28.3M in Q3 (from $9.6M) due to $4.1M in acquisition-related transaction costs and $3.0M in restructuring charges, partially offset by the absence of a $9.5M gain on legacy liability extinguishment recorded in 2024.
• Segment Performance:
  • Domestic Coke: Adjusted EBITDA declined $14.1M in Q3 to $44.0M, impacted by pricing and volume headwinds.
  • Industrial Services: Adjusted EBITDA increased $4.5M in Q3 to $18.2M, driven by the inclusion of Phoenix Global results, despite lower transloading volumes in the legacy logistics business.
• Tax Benefit: The Company recorded a significant net tax benefit of $20.7M in Q3 and YTD 2025 due to an analysis of capital investments under Section 48 of the Internal Revenue Code, resulting in a negative effective tax rate for the periods.

Guidance, Outlook, and Risks

• Acquisition Integration: The Company is integrating Phoenix Global's operations and internal controls. The purchase price allocation is preliminary, with final adjustments expected within the measurement period.
• Contract Renewals: The Granite City long-term take-or-pay agreement with U.S. Steel was extended through December 31, 2025. However, the Company faces risk regarding the non-renewal of this agreement or the granulated pig iron project, which could trigger impairment charges on the $238.0M carrying value of long-lived assets at that facility.
• Customer Disputes: Algoma Steel Inc. refused to accept additional coke tons at the end of Q3 2025. SunCoke is actively pursuing enforcement of the contract to recover financial losses.
• Liquidity: The Company funded the Phoenix Global acquisition using cash on hand and borrowings from its Revolving Facility. As of September 30, 2025, the Company remains in compliance with all debt covenants (max leverage 4.50:1.00; min interest coverage 2.50:1.00).
• Regulatory Impact: The "One Big Beautiful Bill Act" (OBBBA) enacted in July 2025 has been recognized in the financial statements, impacting deferred tax assets and liabilities.

Investor Verification Checklist

• Granite City Contract Status: Verify the likelihood of contract renewal beyond December 31, 2025, and the potential impact on asset impairment.
• Algoma Steel Dispute: Monitor the resolution of the contract dispute and potential recoveries or losses.
• Phoenix Global Integration: Assess the realization of synergies and the final purchase price allocation, particularly regarding goodwill and intangible assets.
• Coal-to-Coke Yields: Investigate the operational causes of unfavorable yields in the Domestic Coke segment and their persistence.
• Debt Covenants: Confirm continued compliance with leverage and interest coverage ratios given the increased debt load from the acquisition.
