SUNCOKE ENERGY, INC. REPORTS SECOND QUARTER 2020 RESULTS AND REISSUES 2020 GUIDANCE

• Second quarter 2020 net income attributable to SXC was $6.5 million, or $0.08 per share, compared to $2.3 million, or $0.03 per share, in the prior year period. Adjusted EBITDA was $59.0 million in the current period

• SunCoke continues to operate all facilities as an essential business, emphasizing employee health and safety by adhering to federal and state best practices

• Successfully extended near-term expiring customer contracts and completed near-term coke supply relief agreements

• Revised full-year 2020 Adjusted EBITDA guidance of $190 million to $200 million reflecting near-term coke supply relief provided to customers in exchange for extending existing contracts

• Cost savings initiative, including a reduction in workforce, estimated to result in full year savings of approximately $10 million in 2021

LISLE, Ill. (August 3, 2020) - SunCoke Energy, Inc. (NYSE: SXC) today reported results for the second quarter 2020 and provided updates on COVID-19 impact on business and result of customer negotiations.

“We recognize that COVID-19 has significantly impacted the steel industry as evident from recent steel capacity utilization rates. In response to the market challenges presented by COVID-19, we have taken proactive actions to work with our customers and provide near-term coke supply relief in exchange for extending existing contracts,” said Mike Rippey, President and Chief Executive Officer of SunCoke Energy, Inc. “We expect the impact of these short-term relief measures, net of cost savings initiatives, will result in a $40 - $50 million reduction in 2020 Adjusted EBITDA. We are pleased to have successfully addressed short-term market challenges with our customers while simultaneously assuring long term stability for our stakeholders.”

Rippey added, “In addition to the significant progress we have made with our customer contracts, we are also evaluating our cost structure to ensure that we remain a low cost coke and logistics service provider. We have taken certain actions, which while difficult during these unprecedented times, will help better position SunCoke for the future. We anticipate that these initiatives will achieve full year savings of approximately $10 million in 2021. We are also working on a transformational project to produce and sell foundry coke beginning in 2021. This alternative product will provide customer diversification and help address current blast furnace coke market dynamics.”

SECOND QUARTER CONSOLIDATED RESULTS

	Three Months Ended June 30,
(Dollars in millions)	2020		2019		Increase (Decrease)
Revenues	$	338.0	$	407.5	$	(69.5	)
Net income attributable to SXC	$	6.5	$	2.3	$	4.2
Adjusted EBITDA(1)	$	59.0	$	63.1	$	(4.1	)

(1) See definition of Adjusted EBITDA and reconciliation elsewhere in this release.

Revenue in the second quarter 2020 decreased $69.5 million compared to the same prior year period, reflecting the pass through of lower coal prices in our Domestic Coke segment as well as lower volumes in both our Domestic Coke and Logistics segments.

Adjusted EBITDA decreased $4.1 million as compared to the same prior year period. Lower volumes were partly offset by operating and maintenance savings in our Domestic Coke segment.

Net income attributable to SXC increased $4.2 million from the prior year period. The decrease in operating results discussed above was more than offset by lower depreciation expense and the absence of $4.4 million in transaction costs incurred during the prior year period.

SECOND 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.

	Three Months Ended June 30,
(Dollars in millions, except per ton amounts)	2020		2019		Increase (Decrease)
Revenues	$	323.5	$	378.0	$	(54.5	)
Adjusted EBITDA(1)	$	61.6	$	56.3	$	5.3
Sales volumes (thousands of tons)		977		1,030		(53	)
Adjusted EBITDA per ton(2)	$	63.05	$	54.66	$	8.39

(1) See definition of Adjusted EBITDA and reconciliation elsewhere in this release.

(2) Reflects Domestic Coke Adjusted EBITDA divided by Domestic Coke sales volumes.

Revenues decreased $54.5 million largely due to the pass through of lower coal costs, which decreased revenues by $42.8 million. Higher sales volumes from rebuilt ovens at our Indiana Harbor facility were more than offset by the impact of volume relief provided to our customers in 2020.

On a full year basis, we expect the volume relief provided to our customers to be approximately 550,000 tons and we now expect to produce approximately 3,750,000 tons of coke in 2020.

Adjusted EBITDA increased $5.3 million as operating and maintenance cost savings across the domestic coke fleet offset the decrease in volume discussed above.

2

Logistics

Logistics consists of the handling and mixing services of coal and other aggregates at our Convent Marine Terminal (“CMT”), Lake Terminal, Kanawha River Terminals (“KRT”) and Dismal River Terminal (“DRT”).

	Three Months Ended June 30,
(Dollars in millions, except per ton amounts)	2020		2019		Decrease
Revenues	$	7.3	$	19.5	$	(12.2	)
Intersegment sales	$	5.2	$	6.7	$	(1.5	)
Adjusted EBITDA(1)	$	3.0	$	11.8	$	(8.8	)
Tons handled (thousands of tons)		2,853		5,592		(2,739	)

(1) See definition of Adjusted EBITDA and reconciliation elsewhere in this release.

Revenues and Adjusted EBITDA decreased by $12.2 million and $8.8 million, respectively, driven by lower throughput volumes and lower price partially offset by lower operating costs. Lower demand continued to impact coal volumes in the second quarter.

Brazil Coke

Brazil Coke consists of a cokemaking facility in Vitória, Brazil, which we operate for an affiliate of ArcelorMittal.

Revenues and Adjusted EBITDA were $7.2 million and $3.2 million, respectively, during the second quarter 2020, which was lower than revenues and Adjusted EBITDA of $10.0 million and $4.3 million, respectively, during the second quarter 2019, driven by lower sales volumes.

Corporate and Other

Corporate and other expenses, which includes activity from our legacy coal mining business, was $8.8 million during the second quarter 2020, $0.5 million lower than $9.3 million during second quarter 2019. Corporate expenses in the current quarter included foundry related research and development costs of $0.6 million, which was more than offset by favorable employee related expenses as compared to the same prior year period.

2020 Revised Outlook

Our 2020 guidance, is as follows:

• Domestic coke production is expected to be approximately 3.75 million tons

• Domestic coke Adjusted EBITDA/ton is expected to be between $53 to $54/ton

• Consolidated Adjusted EBITDA is expected to be between $190 to $200 million

• Capital expenditures are projected to be approximately $80 million which includes approximately $12 million for foundry coke

• Free Cash Flow is estimated to be between $36 million and $56 million

• Cash taxes are projected to be between $0 to $4 million

DEFINITIONS

• Adjusted EBITDA represents earnings before interest, taxes, depreciation and amortization (“EBITDA”), adjusted for any impairments, gain on extinguishment of debt, changes to our contingent consideration liability related to our acquisition of CMT, and/or transaction costs incurred as part of the Simplification Transaction. EBITDA and Adjusted EBITDA do not represent and should not be considered alternatives to net income or operating income under accounting principles generally accepted in the 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 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 GAAP, and they should not be considered a substitute for net income or any other measure of financial performance presented in accordance with GAAP.

• Free Cash Flow (FCF) represents operating cash flow adjusted for capital expenditures. Management believes FCF is an important measure of liquidity. FCF is not a measure calculated in accordance with GAAP, and they should not be considered a substitute for operating cash flow or any other measure of financial performance presented in accordance with GAAP.

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