• Updating full-year 2025 Consolidated Adjusted EBITDA ⁽¹⁾ guidance range to $220 million - $225 million

SunCoke Energy, Inc. (NYSE: SXC) today reported results for third quarter 2025 and provided updated guidance for 2025.

"Our third quarter Consolidated Adjusted EBITDA of $59.1 million included two months of results from the addition of Phoenix Global. While the Domestic Coke segment continued to be impacted by the unfavorable mix of contract and spot coke sales, our new Industrial Services segment, which includes Phoenix Global and our logistics business, operated well during the quarter. Phoenix performed in line with our expectations, but volumes at our logistics terminals did not recover to the degree we previously expected due to persistent weak market conditions. Additionally, we have extended our cokemaking contract with U.S. Steel at Granite City through the end of 2025," said Katherine Gates, President and CEO of SunCoke Energy, Inc. "Our updated full-year Consolidated Adjusted EBITDA range of $220 million to $225 million reflects the addition of five months of Phoenix Global results, partially offset by the deferral of approximately 200,000 tons of coke sales due to a breach of contract by one of our coke customers. We are actively pursuing all avenues to enforce the contract." Gates continued, "As SunCoke has proven in the past, we are well-equipped to navigate challenging market conditions. We are excited to have Phoenix Global as part of SunCoke, and for the new opportunities that the business brings. The integration is progressing well, and we expect to begin realizing synergies from the acquisition in 2026."

THIRD QUARTER CONSOLIDATED RESULTS

Revenues in the third quarter of 2025 decreased $3.1 million as compared to the same prior year period, primarily driven by lower pricing and volumes due to the change in mix of contract and spot coke sales, as well as lower contract extension economics at Granite City in the Domestic Coke segment, partially offset by the addition of Phoenix Global in the Industrial Services segment.

Net income attributable to SXC decreased $8.5 million from the same prior year period, primarily driven by the change in mix of contract and spot coke sales, lower contract extension economics at Granite City, the absence of the $9.5 million gain on elimination of the majority of legacy black lung liabilities recorded in the third quarter of 2024, and transaction and restructuring costs of $7.6 million, partially offset by lower income tax expense driven by capital investment tax credits.

Adjusted EBITDA decreased $16.2 million as compared to the same prior year period, primarily driven by lower volumes and pricing due to the change in mix of contract and spot coke sales, lower contract extension economics at Granite City, the absence of the $9.5 million gain on elimination of the majority of legacy black lung liabilities recorded in the third quarter of 2024, and lower volumes at the logistics terminals, partially offset by the inclusion of Phoenix Global results.

THIRD QUARTER SEGMENT RESULTS

Domestic Coke

Domestic Coke consists of cokemaking facilities and heat recovery operations at our Jewell, Indiana Harbor, Haverhill, Granite City and Middletown plants.

Revenues in the third quarter of 2025 decreased $46.1 million as compared to the same prior year period, primarily driven by lower pricing and volumes due to the change in mix of contract and spot coke sales, as well as lower contract extension economics at Granite City.

Adjusted EBITDA in the third quarter of 2025 decreased $14.1 million as compared to the same prior year period, primarily driven by lower volumes and pricing due to the change in mix of contract and spot coke sales, lower contract extension economics at Granite City, and lower volumes driven by lower coal-to-coke yields.

Industrial Services

Industrial Services consists of the handling and mixing services of coal and other aggregates at our logistics terminals, including Convent Marine Terminal ("CMT"), Lake Terminal, and Kanawha River Terminals ("KRT"). Additionally, Industrial Services includes fifteen molten slag removal, handling, and processing operating sites in four countries.

Revenues in the third quarter of 2025 increased $42.7 million as compared to the same prior year period, primarily driven by the addition of two months of Phoenix Global results.

Adjusted EBITDA increased by $4.5 million as compared to the same prior year period, primarily driven by the addition of two months of Phoenix Global results, partially offset by lower volumes at logistics terminals due to market conditions.

Corporate and Other

Corporate and Other, which includes results from our legacy coal mining business and Brazil cokemaking business, was an expense of $3.1 million during the third quarter of 2025, compared to a net positive of $3.5 million during the third quarter of 2024, primarily due to the absence of the $9.5 million gain on elimination of the majority of legacy black lung liabilities recorded in the third quarter of 2024.

2025 REVISED OUTLOOK

Our 2025 revised guidance reflects the addition of Phoenix Global and estimated impact of the deferral of coke sales tons due to a customer's breach of contract on Consolidated Net Income, Consolidated Adjusted EBITDA, and Operating cash flow.

Our revised 2025 guidance is as follows:

• Domestic Coke total production is expected to be approximately 3.9 million tons
• Consolidated Net Income is expected to be between $48 million and $58 million
• Consolidated Adjusted EBITDA is expected to be between $220 million and $225 million
• Capital expenditures are projected to be approximately $70 million
• Operating cash flow is estimated to be between $62 million and $72 million
• Cash taxes are projected to be between $4 million and $7 million

Disclaimer: The Company's 2025 outlook and guidance are based on the Company's current estimates and assumptions that are subject to change and may be outside the control of the Company. If actual results vary from these estimates and assumptions, the Company's expectations may change. There can be no assurances that SunCoke will achieve the results expressed by this outlook and guidance.

NON-GAAP FINANCIAL MEASURES

In addition to U.S. GAAP measures, this press release contains certain non-GAAP financial measures. These non-GAAP financial measures should not be considered as alternatives to the measures derived in accordance with U.S. GAAP. Non-GAAP financial measures have important limitations as analytical tools, and you should not consider them in isolation or as substitutes for results as reported under U.S. GAAP. Additionally, other companies may calculate non-GAAP metrics differently than we do, thereby limiting their usefulness as a comparative measure. Because of these and other limitations, you should consider our non-GAAP measures only as supplemental to other U.S. GAAP-based financial performance measures, including revenues and net income. Reconciliations to the most comparable GAAP financial measures are included following the presentation of financial and operating results included at the end of this press release.

DEFINITIONS

• Adjusted EBITDA represents earnings before interest, taxes, depreciation and amortization ("EBITDA"), adjusted for any impairments, restructuring costs, gains or losses on extinguishment of debt, gains or losses on derivative instruments, site closure costs and/or transaction costs ("Adjusted EBITDA"). EBITDA and Adjusted EBITDA do not represent and should not be considered alternatives to net income or operating income under U.S. GAAP and may not be comparable to other similarly titled measures in other businesses. Management believes Adjusted EBITDA is an important measure in assessing operating performance. Adjusted EBITDA provides useful information to investors because it highlights trends in our business that may not otherwise be apparent when relying solely on U.S. GAAP measures and because it eliminates items that have less bearing on our operating performance. EBITDA and Adjusted EBITDA are not measures calculated in accordance with U.S. GAAP, and they should not be considered a substitute for net income, or any other measure of financial performance presented in accordance with U.S. GAAP.

• Adjusted EBITDA attributable to SXC represents Adjusted EBITDA less Adjusted EBITDA attributable to noncontrolling interests.
