SUNCOKE ENERGY, INC. ANNOUNCES STRONG FIRST QUARTER 2019 RESULTS

• Net income attributable to SXC was $9.8 million, or $0.15 per share, in the current period compared to $8.7 million, or $0.13 per share, in the prior year period

• Operating cash flow was $35.3 million in the current period compared to $57.3 million in the prior year period

• Adjusted EBITDA for the quarter was $67.3 million, up 5 percent, versus the prior year period

• Reaffirm full-year 2019 Consolidated Adjusted EBITDA guidance range of $265 million to $275 million

LISLE, Ill. (April 24, 2019) - SunCoke Energy, Inc. (NYSE: SXC) today reported results for the first quarter 2019, reflecting the strong performance at our Domestic Coke segment, including higher sales volumes at our Indiana Harbor facility driven by our oven rebuild initiative, which continues to deliver sustained operating results.

“We are pleased with the operational performance that our team delivered in the quarter despite the adverse weather conditions, which impacted operations across our business. We continue to execute against our 2019 objectives, and our record setting first quarter performance has positioned us well to achieve our full-year Adjusted EBITDA guidance,” said Mike Rippey, President and Chief Executive Officer of SunCoke Energy, Inc.

The Company has filed a FormS-4 Registration Statement in connection with the announced acquisition of all outstanding common units of SunCoke Energy Partners, L.P. (NYSE: SXCP) not already owned by SXC in astock-for-unit exchange transaction (the “Simplification Transaction”). Rippey continued, “Our team has made significant progress working to close the Simplification Transaction and we continue to be encouraged by the benefits it will allow us to achieve, including a simplified corporate structure, increased liquidity and improved financial flexibility. Together, these benefits will best-position the Company to execute against our strategic objectives and create immediate and long-term value for SunCoke stakeholders.”

FIRST QUARTER CONSOLIDATED RESULTS

	Three Months Ended March 31,
(Dollars in millions)	2019		2018		Increase
Revenues	$	391.3	$	350.5	$	40.8
Adjusted EBITDA(1)	$	67.3	$	64.0	$	3.3
Net income attributable to SXC	$	9.8	$	8.7	$	1.1

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

Revenues during the first quarter 2019 increased $40.8 million compared to the prior year period, primarily reflecting the pass-through of higher coal prices as well as higher sales volumes in our Domestic Coke segment.

Adjusted EBITDA during the first quarter 2019 increased $3.3 million to $67.3 million, driven by improved performance in our Domestic Coke segment.

Net income attributable to SXC was $9.8 million, or $0.15 per share, for the first quarter 2019. The results reflect improved operating results discussed above partially offset by higher depreciation expense, primarily due to the revisions in the estimated useful lives of certain assets in our Domestic Coke segment made during the third quarter 2018.

FIRST 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 March 31,
(Dollars in millions, except per ton amounts)	2019		2018		Increase
Revenues	$	359.3	$	318.1	$	41.2
Adjusted EBITDA(1)	$	58.5	$	54.3	$	4.2
Sales volumes (thousands of tons)		1,004		974		30
Adjusted EBITDA per ton(2)	$	58.27	$	55.75	$	2.52

(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 increased $41.2 million primarily reflecting the pass-through of higher coal prices and increased sales volumes.

Adjusted EBITDA increased $4.2 million and benefited $2.6 million from higher volumes primarily due to the performance of the rebuilt ovens at our Indiana Harbor facility. Additionally, the timing of planned outage costs resulted in a benefit of $1.0 million as compared to the prior year period. The remaining improvement was due to an increase in coal cost recovery and yields driven by higher coal prices during the current period. This benefit was partially offset by the impact from heavy rainfalls, which elevated coal moisture levels and negatively impactedcoal-to-coke yields and Adjusted EBITDA.

Logistics

Logistics consists of the handling and mixing services of coal and other aggregates operated by SunCoke Energy Partners, L.P. at our Convent Marine Terminal (“CMT”), Lake Terminal and Kanawha River Terminals (“KRT”). Additionally, Dismal River Terminal (“DRT”) is operated by SXC.

	Three Months Ended March 31,

(2) Reflects inbound tons handled during the period.

(3) Reflects tons billed undertake-or-pay contracts where services have not yet been performed.

Revenues were reasonably consistent with the prior year period. Adjusted EBITDA decreased by $0.9 million, driven primarily by incremental high water costs at CMT during the current period.

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 $9.7 million and $4.5 million, respectively, during the first quarter 2019, which was comparable to Revenues and Adjusted EBITDA of $10.1 million and $4.7 million, respectively, during the first quarter 2018.

Corporate and Other

Corporate and other expenses, which include costs related to our legacy coal mining business, were $8.4 million during the first quarter 2019, which was comparable with the prior year period of $8.6 million.

2019 OUTLOOK

Our 2019 guidance, which does not include the benefit from the Simplification Transaction, is as follows:

• Domestic coke production is expected to be approximately 4.1 million tons

• Consolidated Adjusted EBITDA is expected to be between $265 to $275 million

• Adjusted EBITDA attributable to SXC is expected to be between $182 to $188 million, reflecting the impact of public ownership in SXCP

• Capital expenditures are projected to be between $110 to $120 million, including $40 million to $48 million related to our Indiana Harbor oven rebuild project and approximately $6 million related to completing our Granite City gas sharing project

DEFINITIONS

• Adjusted EBITDA represents earnings before interest, taxes, depreciation and amortization (“EBITDA”), adjusted for any impairments, loss 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 of the operating performance and liquidity of the Company’s net assets and its ability to incur and service debt, fund capital expenditures and make distributions. 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 and liquidity. EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP, and they should not be considered a substitute for net income, 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.
