Notes to the Consolidated Financial Statements

1. General

Description of Business

SunCoke Energy, Inc. (“SunCoke Energy,” “Company,” "we," "our" and "us") is an independent owner and operator of five cokemaking facilities in the United States ("U.S."), which consists of our Haverhill Coke Company LLC ("Haverhill"), Middletown Coke Company, LLC ("Middletown"), Gateway Energy and Coke Company, LLC ("Granite City"), Jewell Coke Company, L.P. ("Jewell") and Indiana Harbor Coke Company ("Indiana Harbor") cokemaking facilities. Internationally, we operate a cokemaking facility in Brazil. We hold a 49 percent investment in a cokemaking joint venture with VISA Steel Limited in India ("VISA SunCoke"), which was fully impaired in 2015, and consequently, beginning in the fourth quarter of 2015, we no longer included our share of VISA SunCoke in our financial results.

Additionally, we own and operate a coal logistics business, which provides coal handling and/or mixing services to third-party customers as well as to our own cokemaking facilities. Our coal logistics business consists of Convent Marine Terminal ("CMT"), Kanawha River Terminals, LLC ("KRT"), SunCoke Lake Terminal, LLC ("Lake Terminal") and Dismal River Terminal, LLC ("DRT").

Our consolidated financial statements include SunCoke Energy Partners, L.P. (the "Partnership"), a publicly-traded partnership. At June 30, 2017, we owned the general partner of the Partnership, which consists of a 2.0 percent ownership interest and incentive distribution rights, and owned a 57.0 percent limited partner interest in the Partnership. The remaining 41.0 percent interest in the Partnership was held by public unitholders. SunCoke is considered the primary beneficiary of the Partnership as it has the power to direct the activities that most significantly impact the Partnership's economic performance.

Until April 2016, when the business was disposed of, we also controlled coal mining operations in Virginia and West Virginia.

Incorporated in Delaware in 2010 and headquartered in Lisle, Illinois, we became a publicly-traded company in 2011 and our stock is listed on the New York Stock Exchange (“NYSE”) under the symbol “SXC.”

Basis of Presentation

The accompanying unaudited consolidated financial statements included herein have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim reporting. Certain information and disclosures normally included in financial statements have been omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In management’s opinion, the financial statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair presentation of the results of operations, financial position and cash flows for the periods presented. The results of operations for the periods ended June 30, 2017 are not necessarily indicative of the operating results expected for the entire year. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016.

New Accounting Pronouncements

In May 2014, Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Subsequently, the FASB has issued various ASUs to provide further clarification around certain aspects of ASC 606. This standard will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and early adoption is permitted on a limited basis. Our implementation team has gained an understanding of the standard’s revenue recognition model and is completing the analysis and documentation of our contract details for impacts under the new revenue recognition model. Based on the current status of our assessment, we expect the timing of our revenue recognition to generally remain the same under the new standard on an annual basis. Deferred revenue at Convent Marine Terminal may be recognized on a more accelerated basis during quarterly periods within the year based on facts and circumstances considered at each quarter under the new guidance. The Company expects to adopt this standard on January 1, 2018 using the modified retrospective method.

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires lessees to be recognized as assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. It is effective for annual and interim periods in fiscal years beginning after December 15, 2018, with early

6

adoption permitted. The standard requires the use of a modified retrospective transition method. A multi-disciplined implementation team has gained an understanding of the accounting and disclosure provisions of the standard and is in the process of analyzing the impacts to our business, including the development of new accounting processes to account for our leases and support the required disclosures. While we are still evaluating the impact of adopting this standard, we expect that upon adoption the right-of-use assets and lease liabilities, such as various plant equipment rentals and the lease of our corporate office space, will increase the reported assets and liabilities on our Consolidated Balance Sheets. The Company expects to adopt this standard on January 1, 2019.

2. Inventories

The components of inventories were as follows:

	June 30, 2017		December 31, 2016
	(Dollars in millions)
Coal	$	72.0	$	49.4
Coke	8.4		7.7
Materials, supplies and other	36.0		35.4
Total inventories	$	116.4	$	92.5

3. Goodwill and Other Intangible Assets

Goodwill, which represents the excess of the purchase price over the fair value of net assets acquired, is tested for impairment as of October 1 of each year, or when events occur or circumstances change that would, more likely than not, reduce the fair value of a reporting unit to below its carrying value. Goodwill allocated to our Domestic Coke and Coal Logistics segments was $3.4 million and $73.5 million at both June 30, 2017 and December 31, 2016, respectively.

The components of intangible assets were as follows:

		June 30, 2017						December 31, 2016
	Weighted - Average Remaining Amortization Years	Gross Carrying Amount		Accumulated Amortization		Net		Gross Carrying Amount		Accumulated Amortization		Net
		(Dollars in millions)
Customer contracts	5	$	31.7	$	11.8	$	19.9	$	31.7	$	9.9	$	21.8
Customer relationships	14	28.7		4.7		24.0		28.7		3.8		24.9
Permits	25	139.0		9.7		129.3		139.0		7.1		131.9
Trade name	1	1.2		0.9		0.3		1.2		0.8		0.4
Total		$	200.6	$	27.1	$	173.5	$	200.6	$	21.6	$	179.0

The permits above represent the environmental and operational permits required to operate a coal export terminal in accordance with the United States Environmental Protection Agency and other regulatory bodies. Intangible assets are amortized over their useful lives in a manner that reflects the pattern in which the economic benefit of the asset is consumed. The permits’ useful lives were estimated to be 27 years at acquisition based on the expected useful life of the significant operating equipment at the facility. These permits have an average remaining renewal term of approximately 3.9 years. The permits were renewed regularly prior to our acquisition of CMT. We also have historical experience of renewing and extending similar arrangements at our other facilities and intend to continue to renew our permits as they come up for renewal for the foreseeable future.

Total amortization expense for intangible assets subject to amortization was $2.8 million and $5.5 million for the three and six months ended June 30, 2017, respectively, and $2.9 million and $5.6 million for the three and six months ended June 30, 2016, respectively.

4. Income Taxes

At the end of each interim period, we make our best estimate of the effective tax rate expected to be applicable for the full fiscal year and the impact of discrete items, if any, and adjust the rate as necessary.

The Company recorded income tax expense of $4.7 million and $70.9 million during the three and six months ended June 30, 2017, respectively. Income tax expense during the three months ended June 30, 2017 was driven primarily by a valuation allowance of $4.9 million recorded as a result of changes in future state allocation assumptions partially offset by a state income tax benefit of $2.5 million related to the filing of an amended state tax return. Income tax expense during the six months ended June 30, 2017, also included the impacts of the Internal Revenue Service ("IRS") announcement of its final regulations on qualifying income in January 2017, discussed below.

In January 2017, the IRS announced its decision to exclude cokemaking as a qualifying income generating activity in its final regulations (the "Final Regulations") issued under section 7704(d)(1)(E) of the Internal Revenue Code relating to the qualifying income exception for publicly traded partnerships. However, the Final Regulations include a transition period for activities that were reasonably interpreted to be qualifying income and carried on by publicly traded partnerships prior to the Final Regulations. The Partnership previously received a will-level opinion from its counsel, Vinson & Elkins LLP, that the Partnership's cokemaking operations generated qualifying income prior to the Final Regulations. Therefore, the Partnership believes it had a reasonable basis to conclude its cokemaking operations were considered qualifying income before the issuance of the new regulations and as such expects to maintain its treatment as a partnership through the transition period. Cokemaking entities in the Partnership will become taxable as corporations on January 1, 2028, after the transition period ends.

As a result of the Final Regulations discussed above, the Partnership recorded deferred income tax expense of $148.6 million to set up its initial deferred income tax liability during the first quarter of 2017, primarily related to differences in the book and tax basis of fixed assets, which are expected to exist at the end of the 10-year transition period when the cokemaking operations become taxable.  As the Company consolidates the Partnership, the entire deferred income tax expense was recognized during the first quarter of 2017. However, the Company had already recorded $84.4 million of the deferred income tax liability in its financial statements related to the Company's share of the deferred tax liability for the book and tax differences in its investment in the Partnership. Therefore, the net impact to the Company’s deferred tax expense was $64.2 million during the six months ended June 30, 2017. This incremental tax impact is solely attributable to the Partnership’s public unitholders. As such, an equal reduction to noncontrolling interest was recorded. As a result, the Final Regulations have no impact to net income attributable to the Company.

The Company recorded income tax expense of zero and $3.3 million for the three and six months ended June 30, 2016, resulting in effective tax rates of zero percent and 19.5 percent, respectively, as compared to the 35.0 percent federal statutory rate, primarily due to the impact of earnings attributable to noncontrolling ownership interests in partnerships.

On January 17, 2012, SunCoke Energy and Sunoco, Inc. entered into a tax sharing agreement that governs the parties’ respective rights, responsibilities and obligations with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and other matters regarding taxes. SunCoke Energy will continue to monitor the utilization of all tax attributes subject to the tax sharing agreement as applicable tax returns are filed or as tax examinations progress and will record additional adjustments when necessary, consistent with the terms of the tax sharing agreement.

Issuance of 2025 Partnership Senior Notes

In May 2017, the Partnership issued $630.0 million aggregate principal amount of senior notes with an interest rate of 7.5 percentdue in May 2025. The Partnership received proceeds of $620.6 million, net of an original issue discount of $9.4 million. The Partnership incurred debt issuance costs related to this transaction of $11.8 million, which were included in long-term debt and financing obligation on the Consolidated Balance Sheets as of June 30, 2017. The 2025 Partnership Senior Notes are the senior unsecured obligations of the Partnership, and are guaranteed on a senior unsecured basis by each of the Partnership’s existing and certain future subsidiaries (other than SunCoke Energy Partners Finance Corp.). Interest on the 2025 Partnership Senior Notes is payable semi-annually in cash in arrears on June 15 and December 15 of each year, commencing on December 15, 2017.

The Partnership may redeem some or all of the 2025 Partnership Senior Notes at any time on or after June 15, 2020 at specified redemption prices plus accrued and unpaid interest, if any, to the redemption date. Before June 15, 2020, and following certain equity offerings, the Partnership also may redeem up to 35% of the 2025 Partnership Senior Notes at a price equal to 107.50% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date. In addition, at any time prior to June 15, 2020, the Partnership may redeem some or all of the 2025 Partnership Senior Notes at a price equal to 100% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date, plus a “make-whole” premium.

The Partnership is obligated to offer to purchase all or a portion of the 2025 Partnership Senior Notes at a price of (a) 101% of their principal amount, together with accrued and unpaid interest, if any, to the date of purchase, upon the occurrence of certain change of control events and (b) 100% of their principal amount, together with accrued and unpaid interest, if any, to the date of purchase, upon the occurrence of certain asset dispositions. These restrictions and prohibitions are subject to certain qualifications and exceptions set forth in the Indenture, including without limitation, reinvestment rights with respect to the proceeds of asset dispositions.

The Indenture contains covenants that, among other things, limit the Partnership’s ability and the ability of certain of the Partnership’s subsidiaries to (i) incur indebtedness, (ii) pay dividends or make other distributions, (ii) prepay, redeem or repurchase certain subordinated debt, (iv) make loans and investments, (v) sell assets, (vi) incur liens, (vii) enter into transactions with affiliates, (viii) enter into agreements restricting the ability of subsidiaries to pay dividends and (ix) consolidate or merge.

Purchase and Redemption of 2020 Partnership Senior Notes and Repayment of the Partnership Term Loan

During the second quarter of 2017, the Partnership used the proceeds from the issuance of the 2025 Partnership Notes to purchase and redeem all of its 2020 Partnership Notes, including principal of $463.0 million and a premium of $18.7 million, and to repay the $50.0 millionoutstanding on the Partnership Term Loan. As a result, during the three and six months ended

9

June 30, 2017, the Partnership recorded a loss on extinguishment of debt on the Consolidated Statement of Operations of $19.1 million, which included the premium paid and a write-off of unamortized debt issuance costs of $7.0 million partly offset by a write-off of unamortized premiums of $6.6 million.

Revolving Facility

In February 2017, the Company extended the maturity of its Revolving Facility to December 2018 and reduced its capacity by $25.0 million to $125.0 million, resulting in additional debt issuance costs of $0.6 million, which were included in long-term debt and financing obligation on the Consolidated Balance Sheets as of June 30, 2017. Additionally, the Company recorded a loss on extinguishment of debt on the Consolidated Statement of Operations of $0.1 million, representing a write-off of unamortized debt issuance costs, during the six months ended June 30, 2017.

In May 2017, the Company amended and restated its Revolving Facility, which extended its maturity date to May 2022 and reduced its capacity to $100.0 million, resulting in additional debt issuance costs of $1.1 million, which were included in long-term debt and financing obligation on the Consolidated Balance Sheets as of June 30, 2017. Additionally, the Company recorded a loss on extinguishment of debt on the Consolidated Statement of Operations of $0.3 million, representing a write-off of unamortized debt issuance costs, during the three and six months ended June 30, 2017. As of June 30, 2017, the Revolving Facility had letters of credit outstanding of $29.3 million and no outstanding balance, leaving $70.7 million available.

Partnership Revolver

In May 2017, the Partnership amended and restated the Partnership Revolver, which increased the Partnership's capacity from $250.0 million to $285.0 million and extended the maturity to May 2022, resulting in additional debt issuance costs of $3.0 million, which were included in long-term debt and financing obligation on the Consolidated Balance Sheets as of June 30, 2017. Additionally, the Partnership recorded a loss on extinguishment of debt on the Consolidated Statement of Operations of $0.8 million, representing a write-off of unamortized debt issuance costs, during the three and six months ended June 30, 2017.

The Partnership repaid the revolver outstanding balance of $172.0 million and borrowed $100.0 million under the amended and restated credit facility during the second quarter of 2017. As of June 30, 2017, the Partnership had $1.9 million of letters of credit outstanding and an outstanding balance of$100.0 million, leaving $183.1 million available.

Partnership's Promissory Note

During the three and six months ended June 30, 2017, the Partnership repaid $0.3 million and $0.6 million, respectively, of principal on the Partnership's Promissory Note. The Partnership intends to repay the outstanding balance on the Partnership's Promissory Note of $112.6 million in August 2017, primarily using available borrowing capacity under the Partnership Revolver.

Covenants

Under the terms of the Company's credit agreement, the Company is subject to a maximum leverage ratio of 3.25:1.00 and a minimum consolidated interest coverage ratio of 2.75:1.00. Under the terms of the Partnership's credit agreement, the Partnership is subject to a maximum consolidated leverage ratio of 4.5:1.0prior to June 30, 2020 and 4.0:1.0 after June 30, 2020 and a minimum consolidated interest coverage ratio of 2.5:1.0. The Company's and Partnership's credit agreements contain other covenants and events of default that are customary for similar agreements and may limit our ability to take various actions including our ability to pay a dividend or repurchase our stock.

Under the terms of the Promissory Note, Raven Energy LLC, a wholly-owned subsidiary of the Partnership, is subject to a maximum leverage ratio of 5.0:1.0 for any fiscal quarter ending prior to August 12, 2018. For any fiscal quarter ending on or after August 12, 2018 the maximum leverage ratio is 4.5:1.0. Additionally in order to make restricted payments, Raven Energy LLC is subject to a fixed charge ratio of 1.0:1.0.

If we fail to perform our obligations under these and other covenants, the lenders' credit commitment could be terminated and any outstanding borrowings, together with accrued interest, under the Revolving Facility, Partnership Revolver, and Promissory Note could be declared immediately due and payable. The Company and the Partnership have a cross default provision that applies to our indebtedness having a principal amount in excess of $35 million.

As of June 30, 2017, the Company and the Partnership were in compliance with all applicable debt covenants. We do not anticipate violation of these covenants nor do we anticipate that any of these covenants will restrict our operations or our ability to obtain additional financing.

8. Commitments and Contingent Liabilities

Legal Matters

SunCoke Energy is party to an omnibus agreement pursuant to which we will provide indemnification to the Partnership upon the occurrence of certain potential adverse events under certain coke sales agreements, indemnification of certain environmental costs and preferential rights for growth opportunities.

The United States Environmental Protection Agency ("EPA") issued Notices of Violations (“NOVs”) for our Haverhill and Granite City cokemaking facilities which stemmed from alleged violations of our air emission operating permits for these facilities. We are working in a cooperative manner with the EPA, the Ohio Environmental Protection Agency and the Illinois Environmental Protection Agency to address the allegations, and have entered into a consent decree in federal district court with these parties. The consent decree includes a $2.2 million civil penalty payment, which was paid in December 2014, as well as capital projects underway to improve the reliability of the energy recovery systems and enhance environmental performance at the Haverhill and Granite City facilities. We anticipate spending between approximately $140 million and $145 million related to these projects, of which we have spent approximately $101 million to date. The remaining capital is expected to be spent through the first quarter of 2019. A portion of the proceeds from the Partnership's initial public offering and subsequent dropdowns are expected to be used to fund $119 million of these environmental remediation projects. Pursuant to the omnibus agreement, any amounts that the Partnership spends on these projects in excess of the $119 million will be reimbursed by the Company.

SunCoke Energy has also received NOVs, Findings of Violations ("FOVs"), and information requests from the EPA related to our Indiana Harbor cokemaking facility, which allege violations of certain air operating permit conditions for this facility. The Clean Air Act (the "CAA") provides the EPA with the authority to issue, among other actions, an order to enforce a State Implementation Plan ("SIP") 30 days after an NOV. The CAA also authorizes EPA enforcement of other non-SIP requirements immediately after an FOV. Generally, an NOV applies to SIPs and requires the EPA to wait 30 days, while an FOV applies to all other provisions (such as federal regulations) of the CAA, and has no waiting period. The NOVs and/or FOVs were received in 2010, 2012, 2013, 2015 and 2016. After discussions with the EPA and the Indiana Department of Environmental Management (“IDEM”) in 2010, resolution of the NOVs/FOVs was postponed by mutual agreement because of ongoing discussions regarding the NOVs at Haverhill and Granite City. In January 2012, the Company began working in a cooperative manner to address the allegations with the EPA, the IDEM and Cokenergy, Inc., an independent power producer that owns and operates an energy facility, including heat recovery equipment and a flue gas desulfurization system, that processes hot flue gas from our Indiana Harbor facility to produce steam and electricity and to reduce the sulfur and particulate content of such flue gas. The EPA, IDEM, SunCoke Energy and Cokenergy, Inc. have met regularly since those discussions commenced, and will continue to meet regularly in 2017 to attempt to agree upon a settlement of the NOVs and FOVs. Capital projects are underway to address items that may be required in conjunction with a settlement of the NOVs/FOVs. Any such settlement likely will require payment of a penalty for alleged past violations as well as undertaking capital projects to achieve

11

compliance, and possibly enhance reliability and environmental performance of our Indiana Harbor facility. The settlement of most NOVs and FOVs typically involves first agreeing on injunctive relief and then agreeing on any appropriate penalty in light of the violations and the scope and cost of any injunctive relief.

Over the past several years, EPA, IDEM, SunCoke Energy and Cokenergy, Inc. have focused on the nature and extent of any injunctive relief to settle the NOVs/FOVs. Despite the negotiations, the scope and cost of any such injunctive relief remains uncertain, including any part of such injunctive relief that would be performed by SunCoke Energy. Likewise, the amount of any civil penalties that SunCoke Energy would be willing to pay in settlement of these claims is uncertain, and is contingent on the cost of any injunctive relief. As a result, SunCoke Energy cannot yet assess the scope or cost of any injunctive relief or potential monetary penalty. Moreover, the Company believes that it has meritorious defenses to many of the claims and that a failure to reach a settlement with the EPA regarding the NOVs and FOVs may lead to litigation in which rulings in the Company's favor on some or all of the allegations are possible. For these reasons, the Company is unable to reliably estimate a range of probable or reasonably possible loss.

The Company is a party to certain other pending and threatened claims, including matters related to commercial and tax disputes, product liability, employment claims, personal injury claims, premises-liability claims, allegations of exposures to toxic substances and general environmental claims. Although the ultimate outcome of these claims cannot be ascertained at this time, it is reasonably possible that some portion of these claims could be resolved unfavorably to the Company. Management of the Company believes that any liability which may arise from claims would not have a material adverse impact on our consolidated financial statements.

Black Lung Benefit Liabilities

The Company has obligations related to coal workers’ pneumoconiosis, or black lung, benefits to certain of our former coal mining employees (and their dependents). Such benefits are provided for under Title IV of the Federal Coal Mine and Safety Act of 1969 and subsequent amendments, as well as for black lung benefits provided in the states of Virginia, Kentucky and West Virginia pursuant to workers’ compensation legislation. The Patient Protection and Affordable Care Act (“PPACA”), which was implemented in 2010, amended previous legislation related to coal workers’ black lung obligations. PPACA provides for the automatic extension of awarded lifetime benefits to surviving spouses and changes the legal criteria used to assess and award claims. We act as a self-insurer for both state and federal black lung benefits and adjust our liability each year based upon actuarial calculations of our expected future payments for these benefits.

Our independent actuarial consultants calculate the present value of the estimated black lung liability annually based on actuarial models utilizing our population of former coal mining employees, historical payout patterns of both the Company and the industry, actuarial mortality rates, disability incidence, medical costs, death benefits, dependents, discount rates and the current federally mandated payout rates. The estimated liability may be impacted by future changes in the statutory mechanisms, modifications by court decisions and changes in filing patterns driven by perceptions of success by claimants and their advisors, the impact of which cannot be estimated. The estimated liability was $50.8 million and $50.2 million as of June 30, 2017 and December 31, 2016, respectively, of which $4.8 million was included in accrued liabilities on the Consolidated Balance Sheets in both periods.

9. Share-Based Compensation

Equity Classified Awards

During the six months ended June 30, 2017, the Company granted share-based compensation to eligible participants under the SunCoke Energy, Inc. Long-Term Performance Enhancement Plan (“SunCoke LTPEP”). All awards vest immediately upon a change in control and a qualifying termination of employment as defined by the SunCoke LTPEP.

Stock Options

The Company granted the following stock options during the six months ended June 30, 2017 with an exercise price equal to the closing price of our common stock on the date of grant.

		Weighted Average Per Share
	No. of Shares	Exercise Price		Grant Date Fair Value
Traditional stock options	84,332	$	9.85	$	5.17
Performance based options	80,595	$	9.85	$	4.55

The stock options vest in three equal annual installments beginning one year from the date of grant. In order to become exercisable, the performance based options also require the closing price of the Company's common stock to reach or

12

exceed $14.78, or 150 percent of $9.85, for any 15 trading days during the three year period beginning on the grant date. The stock options expire ten years from the date of grant.

The Company calculates the value of each employee stock option, estimated on the date of grant, using the Black-Scholes option pricing model with a Monte Carlo simulation for the performance based options. The weighted-average fair value of employee stock options granted during the six months ended June 30, 2017 was based on using the following weighted-average assumptions:

	Six Months Ended June 30, 2017
Risk-free interest rate	2	%
Expected term	6 years
Volatility	54	%
Dividend yield	—	%

The risk-free interest rate assumption is based on the U.S. Treasury yield curve at the date of grant for periods which approximate the expected life of the option. The expected term of the employee options represent the average contractual term adjusted by the average vesting period of each option tranche. We used a blended expected volatility assumption that incorporates 90 percent historical volatility and 10 percent implied volatility. The historical volatility is calculated based on our historical daily stock returns over the options' expected term. The implied volatility is calculated based on our near-the-money call options traded over the 90-day period preceding the valuation date. The dividend yield assumption is based on the Company’s expectation of dividend payouts at the time of grant.

Restricted Stock Units Settled in Shares

The Company issued 22,628 stock-settled restricted stock units (“RSUs”) to certain employees for shares of the Company’s common stock during the six months ended June 30, 2017. The weighted average grant date fair value was $9.85 per share. The RSUs vest in three annual installments beginning one year from the date of grant. All awards vest immediately upon a change in control as defined by the SunCoke LTPEP.

Performance Share Units

The Company granted the following performance share units ("PSUs") for shares of the Company's common stock during the six months ended June 30, 2017 that vest on December 31, 2019:

	Shares	Fair Value per Share
PSUs(1)(2)	237,610	$	11.40

(1) The PSU awards are split 50/50 between the Company's three year cumulative Adjusted EBITDA performance measure and the Company's three year average pre-tax return on capital performance measure for its coke and logistics businesses and unallocated corporate expenses.

(2) The number of PSU's ultimately awarded will be determined by the above performance versus targets and the Company's three year total shareholder return ("TSR") as compared to the TSR of the companies making up the Nasdaq Iron & Steel Index ("TSR Modifier"). The TSR Modifier can impact the payout between 50 percent and 150 percent of the Company's final performance measure results.

The award may vest between zero and 250 percent of the original units granted. The fair value of the PSUs granted during the six months ended June 30, 2017 is based on the closing price of our common stock on the date of grant as well as a Monte Carlo simulation for the valuation of the TSR Modifier.

Liability Classified Awards

Restricted Stock Units Settled in Cash

During the six months ended June 30, 2017, the Company issued 95,364 restricted stock units to be settled in cash ("Cash RSUs"), which vest in three annual installments beginning one year from the grant date. The weighted average grant date fair value of the Cash RSUs granted during the six months ended June 30, 2017 was $9.85 and was based on the closing price of our common stock on the day of grant.

The Cash RSU liability at June 30, 2017 was adjusted based on the closing price of our common stock on June 30, 2017 of $10.90 per share. The liability at June 30, 2017 was $0.6 million, of which $0.4 million was included in accrued liabilities and $0.2 million was included in other deferred credits and liabilities on the Consolidated Balance Sheets.

Cash Incentive Award

The Company also granted share-based compensation to eligible participants under the SunCoke Energy, Inc. Long-Term Cash Incentive Plan ("SunCoke LTCIP"), which became effective January 1, 2016. The SunCoke LTCIP is designed to provide for performance-based, cash-settled awards. All awards vest immediately upon a change in control and a qualifying termination of employment as defined by the SunCoke LTCIP.

The Company issued a grant date fair value award of $0.7 million during the six months ended June 30, 2017 that vest on December 31, 2019. The awards are split 50/50 between the Company's three cumulative Adjusted EBITDA performance and the Company's three year average per-tax return on capital for its coke and logistics businesses and unallocated corporate expense. The ultimate award value will be determined by the performance versus targets and the Company's three year TSR Modifier performance, but will be capped at 250 percent of the target award.

The cash incentive award liability at June 30, 2017 was adjusted based on the Company's three year cumulative Adjusted EBITDA performance and adjusted average pre-tax return on capital for the Company's coke and logistics businesses and unallocated corporate expenses. The cash incentive award liability at June 30, 2017 was $0.4 million, which was included in other deferred credits and liabilities on the Consolidated Balance Sheets.

10. Acquisition of Noncontrolling Interest

Partnership Public Unit Purchase Program

On April 17, 2017, the Company's Board of Directors authorized a program for the Company to purchase outstanding Partnership public units at any time and from time to time in the open market, through privately negotiated transactions, block transactions, or otherwise for a total aggregate cost to the Company not to exceed $50.0 million. During the second quarter of 2017, the Company purchased 1,460,404, or approximately 7 percent, of outstanding Partnership public units in the open market for a total cost of $24.6 million, which resulted in a decrease of $15.4 million in noncontrolling interest on the Consolidated Balance Sheets related to the Partnership's net book value acquired by the Company. The Company decreased its additional paid-in capital balance by $5.8 million on the Consolidated Balance Sheets for the consideration paid in excess of the net book value of the noncontrolling interest acquired, net of a deferred tax adjustment of $3.4 million.

The following table summarizes the effects of the changes in the Company's ownership interest in the Partnership on SunCoke's equity:

	Three months ended			Six months ended
	June 30, 2017
Net income attributable to SunCoke Energy, Inc.	$	(24.2	)	$	(23.2	)
Decrease in SunCoke Energy, Inc. equity for the purchase of additional interest in the Partnership	(5.8		)	(5.8		)
Change from net income attributable to SunCoke Energy, Inc. and transfers to noncontrolling interest	$	(30.0	)	$	(29.0	)

In July 2017, the Company's Board of Directors authorized the Company to purchase an additional $50.0 million of Partnership public units in the open market. Subsequent to June 30, 2017, the Company purchased an additional 131,274 of outstanding Partnership public units in the open market for a total cost of $2.3 million, leaving a remaining public unit purchase program balance of $73.1 million as of July 26, 2017.

11. Earnings per Share

Basic earnings per share (“EPS”) has been computed by dividing net (loss) income available to SunCoke Energy, Inc. by the weighted average number of shares outstanding during the period. Except where the result would be anti-dilutive, diluted earnings per share has been computed to give effect to share-based compensation awards using the treasury stock method.

The following table sets forth the reconciliation of the weighted-average number of common shares used to compute basic EPS to those used to compute diluted EPS:

	Three Months Ended June 30,		Six Months Ended June 30,
	2017	2016	2017	2016
	(Shares in millions)

13. Fair Value Measurement

The Company measures certain financial and non-financial assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. Fair value disclosures are reflected in a three-level hierarchy, maximizing the use of observable inputs and minimizing the use of unobservable inputs.

The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels are defined as follows:

• Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market.

• Level 2 - inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or model-derived valuations in which all significant inputs are observable for substantially the full term of the asset or liability.

• Level 3 - inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability.

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

Certain assets and liabilities are measured at fair value on a recurring basis. The Company's cash equivalents, which amounted to $4.5 million and $4.4 million at June 30, 2017 and December 31, 2016, respectively, were measured at fair value based on quoted prices in active markets for identical assets. These inputs are classified as Level 1 within the valuation hierarchy.

CMT Contingent Consideration

In connection with the CMT acquisition, the Partnership entered into a contingent consideration arrangement that requires the Partnership to make future payments to The Cline Group based on future volume over a specified threshold, price and contract renewals. The fair value of the contingent consideration was estimated based on a probability-weighted analysis

16

using significant inputs that are not observable in the market, or Level 3 inputs. Key assumptions included probability adjusted levels of coal handling services provided by CMT, anticipated price per ton on future sales and probability of contract renewal, including length of future contracts, volume commitment, and anticipated price per ton. The fair value of the contingent consideration at June 30, 2017 and December 31, 2016 was $4.5 million and $4.2 million, respectively, and was included in other deferred credits and liabilities on the Consolidated Balance Sheets. As a result of the increase in fair value, the Partnership recognized $0.3 million of additional expense in costs of products sold and operating expenses on the Consolidated Statements of Operations during the three and six months ended June 30, 2017. During the first quarter of 2016, the Partnership amended the contingent consideration terms with The Cline Group, which resulted in a $3.7 million gain recognized as a reduction to costs of products sold and operating expenses on the Consolidated Statements of Operations during the six months ended June 30, 2016.

Certain Financial Assets and Liabilities not Measured at Fair Value

At June 30, 2017 and December 31, 2016, the fair value of the Company’s total debt was estimated to be $895.4 million and $854.4 million, respectively, compared to a carrying amount of $901.2 million and $858.0 million, respectively. The fair value was estimated by management based upon estimates of debt pricing provided by financial institutions, which are considered Level 2 inputs.

14. Business Segment Information

The Company reports its business through three segments: Domestic Coke, Brazil Coke and Coal Logistics. The Domestic Coke segment includes the Jewell, Indiana Harbor, Haverhill, Granite City and Middletown cokemaking facilities. Each of these facilities produces coke, and all facilities except Jewell and Indiana Harbor recover waste heat, which is converted to steam or electricity through a similar production process. Steam is provided to customers pursuant to steam supply and purchase agreements. Electricity is sold into the regional power market or to AK Steel Holding Corporation ("AK Steel") pursuant to energy sales agreements. Coke sales at each of the Company's five domestic cokemaking facilities are made pursuant to long-term, take-or-pay agreements with ArcelorMittal S.A., AK Steel, and United States Steel Corporation. Each of the coke sales agreements contains pass-through provisions for costs incurred in the cokemaking process, including coal procurement costs (subject to meeting contractual coal-to-coke yields), operating and maintenance expense, costs related to the transportation of coke to the customers, taxes (other than income taxes) and costs associated with changes in regulation, in addition to containing a fixed fee.

The Brazil Coke segment operates a cokemaking facility located in Vitória, Brazil for a project company. The Brazil Coke segment earns income from the Brazilian facility through licensing and operating fees payable to us under long-term contracts with the local project company that will run through at least 2023.

Coal Logistics operations are comprised of CMT, located in Louisiana, KRT, located in West Virginia, SunCoke Lake Terminal, located in Indiana, and DRT, located in Virginia adjacent to our Jewell cokemaking facility. Our coal logistics operations have a collective capacity to mix and transload approximately 40 million tons of coal annually and provide coal handling and/or mixing services to its customers, which include the Partnership's cokemaking facilities and other SunCoke cokemaking facilities. Coal handling and mixing results are presented in the Coal Logistics segment.

Corporate expenses that can be identified with a segment have been included in determining segment results. The remainder is included in Corporate and Other, which also includes activity from our legacy coal mining business, which was historically presented as a separate reportable segment. Prior year periods have been recasted to reflect current presentation.

Segment assets, net of tax are those assets utilized within a specific segment and exclude deferred taxes and current tax receivables.

The Company evaluates the performance of its segments based on segment Adjusted EBITDA, which is defined asearnings before interest, loss (gain) on extinguishment of debt, taxes, depreciation and amortization (“EBITDA”), adjusted for impairments, coal rationalization costs, changes to our contingent consideration liability related to our acquisition of CMT and the expiration of certain acquired contractual obligations. EBITDA and Adjusted EBITDA do not represent and should not be considered alternatives to net income or operating income under 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. Set forth below is additional discussion of the limitations of Adjusted EBITDA as an analytical tool.

Limitations. Other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure. Adjusted EBITDA also has limitations as an analytical tool and should not be considered in isolation or as a substitute for an analysis of our results as reported under GAAP. Some of these limitations include that Adjusted EBITDA:

• does not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments;

• does not reflect items such as depreciation and amortization;

• does not reflect changes in, or cash requirement for, working capital needs;

• does not reflect our interest expense, or the cash requirements necessary to service interest on or principal payments of our debt;

• does not reflect certain other non-cash income and expenses;

• excludes income taxes that may represent a reduction in available cash; and

• includes net income attributable to noncontrolling interests.

Below is a reconciliation of Adjusted EBITDA to net income and net cash provided by operating activities, which are its most directly comparable financial measures calculated and presented in accordance with GAAP:

(1) Prior to the divestiture of our coal mining business, the Company incurred coal rationalization costs including employee severance, contract termination costs and other costs to idle mines incurred during the execution of our coal rationalization plan.

(2) As a result of the increase in fair value of the contingent consideration liability during the second quarter of 2017, the Partnership recognized expense of $0.3 million during the three and six months ended June 30, 2017. The Partnership amended its contingent consideration terms with The Cline Group during the first quarter of 2016. This amendment resulted in a gain of $3.7 million recorded during the six months ended June 30, 2016.

(3) In 2014, we finalized the required permitting and engineering plan for a potential new cokemaking facility to be constructed in Kentucky. However, in June 2017, due to our focus on renewing our existing customer contracts and the lack of any long-term customer commitment for a majority of the facility's capacity, we decided to terminate the project. As a result, during the second quarter of 2017, the Company wrote-off previously capitalized engineering and land deposit costs of $5.3 million. During the second quarter of 2016, the Company wrote-off expiring land deposits related to the project of $1.9 million.

(4) In accordance with the SEC’s May 2016 update of its guidance on the appropriate use of non-GAAP financial measures, Adjusted EBITDA does not include Coal Logistics deferred revenue until it is recognized as GAAP revenue.

(5) Reflects noncontrolling interest in Indiana Harbor and the portion of the Partnership owned by public unitholders.

15. Supplemental Condensed Consolidating Financial Information

Certain 100 percent owned subsidiaries of the Company serve as guarantors of the obligations under the Credit Agreement and $44.6 million of Notes (“Guarantor Subsidiaries”). These guarantees are full and unconditional (subject, in the case of the Guarantor Subsidiaries, to customary release provisions as described below) and joint and several. For purposes of the following footnote, SunCoke Energy, Inc. is referred to as “Issuer.” The indenture dated July 26, 2011 among the Company, the guarantors party thereto and The Bank of New York Mellon Trust Company, N.A., governs subsidiaries designated as “Guarantor Subsidiaries.” All other consolidated subsidiaries of the Company are collectively referred to as “Non-Guarantor Subsidiaries.”

The ability of the Partnership and Indiana Harbor to pay dividends and make loans to the Company is restricted under the partnership agreements of the Partnership and Indiana Harbor, respectively. The credit agreement governing the Partnership’s credit facility and the indenture governing the Partnership Notes contain customary provisions which would potentially restrict the Partnership’s ability to make distributions or loans to the Company under certain circumstances. For the year ended December 31, 2016, less than 25 percent of net assets were restricted. Additionally certain coal mining entities are designated as unrestricted subsidiaries. As such, all the subsidiaries described above are presented as "Non-Guarantor Subsidiaries." There have been no changes to the "Guarantor Subsidiaries" and "Non-Guarantor Subsidiaries" during 2017.

The guarantee of a Guarantor Subsidiary will terminate upon:

• a sale or other disposition of the Guarantor Subsidiary or of all or substantially all of its assets;

• a sale of the majority of the Capital Stock of a Guarantor Subsidiary to a third-party, after which the Guarantor Subsidiary is no longer a "Restricted Subsidiary" in accordance with the indenture governing the Notes;

• the liquidation or dissolution of a Guarantor Subsidiary so long as no "Default" or "Event of Default", as defined under the indenture governing the Notes, has occurred as a result thereof;

• the designation of a Guarantor Subsidiary as an "unrestricted subsidiary" in accordance with the indenture governing the Notes;

• the requirements for defeasance or discharge of the indentures governing the Notes having been satisfied; and

• the release, other than the discharge through payments by a Guarantor Subsidiary, from its guarantee under the Credit Agreement or other indebtedness that resulted in the obligation of the Guarantor Subsidiary under the indenture governing the Notes.

The following supplemental condensed combining and consolidating financial information reflects the Issuer’s separate accounts, the combined accounts of the Guarantor Subsidiaries, the combined accounts of the Non-Guarantor Subsidiaries, the combining and consolidating adjustments and eliminations and the Issuer’s consolidated accounts for the dates and periods indicated. For purposes of the following condensed combining and consolidating information, the Issuer’s investments in its subsidiaries and the Guarantor and Non-Guarantor Subsidiaries’ investments in its subsidiaries are accounted for under the equity method of accounting.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Quarterly Report on Form 10-Q contains certain forward-looking statements of expected future developments, as defined in the Private Securities Litigation Reform Act of 1995. This discussion contains forward-looking statements about our business, operations and industry that involve risks and uncertainties, such as statements regarding our plans, objectives, expectations and intentions. Our future results and financial condition may differ materially from those we currently anticipate as a result of the factors we describe under “Cautionary Statement Concerning Forward-Looking Statements.”

This Management’s Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") is based on financial data derived from the financial statements prepared in accordance with the United States ("U.S.") generally accepted accounting principles (“GAAP”) and certain other financial data that is prepared using non-GAAP measures. For a reconciliation of these non-GAAP measures to the most comparable GAAP components, see “Non-GAAP Financial Measures” at the end of this Item, and Note 14 to our consolidated financial statements.

Our MD&A is provided in addition to the accompanying consolidated financial statements and notes to assist readers in understanding our results of operations, financial condition and cash flow.

Overview

SunCoke Energy, Inc. (“SunCoke Energy,” “Company,” “we,” “our” and “us”) is the largest independent producer of high-quality coke in the Americas, as measured by tons of coke produced each year, and has more than 50 years of coke production experience. Coke is a principal raw material in the blast furnace steelmaking process. Coke is generally produced by heating metallurgical coal in a refractory oven, which releases certain volatile components from the coal, thus transforming the coal into coke. We have designed, developed, built, own and operate five cokemaking facilities in the United States (“U.S.”), which consist of our Haverhill Coke Company LLC ("Haverhill"), Middletown Coke Company, LLC ("Middletown"), Gateway Energy and Coke Company, LLC ("Granite City"), Jewell Coke Company, L.P. ("Jewell") and Indiana Harbor Coke Company ("Indiana Harbor") cokemaking facilities. These five cokemaking facilities have collective nameplate capacity to produce approximately 4.2 million tons of coke per year. Additionally, we have designed and operate one cokemaking facility in Brazil under licensing and operating agreements on behalf of our customers.

All of our U.S. coke sales are made pursuant to long-term, take-or-pay agreements. These coke sales agreements have an average remaining term of approximately seven years and contain pass-through provisions for costs we incur in the cokemaking process, including coal costs (subject to meeting contractual coal-to-coke yields), operating and maintenance expenses, costs related to the transportation of coke to our customers, taxes (other than income taxes) and costs associated with changes in regulation. The coke sales agreement and energy sales agreement with AK Steel Holding Corporation ("AK Steel") at our Haverhill facility are subject to early termination by AK Steel under limited circumstances and provided that AK Steel has given at least two years prior notice of its intention to terminate the agreements and certain other conditions are met. No other coke sales contract has an early termination clause.

Our core business model is predicated on providing steelmakers an alternative to investing capital in their own captive coke production facilities. We direct our marketing efforts principally towards steelmaking customers that require coke for use in their blast furnaces. While our steelmaking customers are operating in an environment that is challenged by global overcapacity, our customers have continued to see increases in steel pricing and positive signals on trade and infrastructure during the first half of 2017. Despite the improved market trends over the last year, AK Steel and United States Steel Corporation ("U.S. Steel") have kept portions of their Ashland Kentucky Works facility and Granite City Works facility idled as they await further signs of market stability. While market challenges remain, our customers continue to comply with the terms of their long-term, take-or-pay contracts with us.

Our Granite City facility and the first phase of our Haverhill facility, or Haverhill I have steam generation facilities, which use hot flue gas from the cokemaking process to produce steam for sale to customers, pursuant to steam supply and purchase agreements. Granite City sells steam to U.S. Steel and Haverhill I provides steam, at minimal cost, to Altivia Petrochemicals, LLC ("Altivia"). Our Middletown facility and the second phase of our Haverhill facility, or Haverhill II, have cogeneration plants that use the hot flue gas created by the cokemaking process to generate electricity, which either is sold into the regional power market or to AK Steel pursuant to energy sales agreements.

30

The following table sets forth information about our cokemaking facilities and our coke and energy sales agreements as of June 30, 2017:

Facility	Location	Customer	Year of Start Up	Contract Expiration	Number of Coke Ovens	Annual Cokemaking Capacity (thousands of tons)	Use of Waste Heat
Owned and Operated:

Equity Method Investment:
VISA SunCoke(2)	Odisha, India	Various	2007	NA	88	440	Steam for power generation
Total					1,238	6,380

(1) Cokemaking capacity represents stated capacity for production of blast furnace coke. The Middletown coke sales agreement provides for coke sales on a “run of oven” basis, which includes both blast furnace coke and small coke. Middletown nameplate capacity on a “run of oven” basis is 578 thousand tons per year.

(2) We hold a 49 percent investment in a cokemaking joint venture with VISA Steel Limited in India ("VISA SunCoke"), which was fully impaired in 2015, and consequently, beginning in the fourth quarter of 2015, we no longer included our share of VISA SunCoke in our financial results. Cokemaking capacity represents 100 percent of VISA SunCoke.

The Partnership owns and operates a coal logistics business, which provides coal handling and/or mixing services to third-party customers as well as to our own cokemaking facilities. The Partnership's coal logistics business consists of Convent Marine Terminal ("CMT"), Kanawha River Terminals, LLC ("KRT") and SunCoke Lake Terminal, LLC ("Lake Terminal"). The Partnership's coal logistics business has collective capacity to mix and/or transload approximately 40 million tons of coal annually and store approximately 3 million tons. CMT is one of the largest export terminals on the U.S. gulf coast and has direct rail access and the capability to transload approximately 15 million tons of coal annually through its operations in Convent, Louisiana. The facility is supported by long-term, take-or-pay contracts with volume commitments covering 10 million tons of its current capacity. KRT is a leading metallurgical and thermal coal mixing and handling terminal service provider with collective capacity to mix and transload approximately 25 million tons of coal annually through operations in West Virginia. The Partnership's terminal located in East Chicago, Indiana, Lake Terminal, provides coal handling and mixing services to our Indiana Harbor cokemaking operations. The Company also owns Dismal River Terminal LLC ("DRT"), which is located in Virginia adjacent to our Jewell cokemaking facility and was formed to accommodate Jewell in its direct procurement of third-party coal, beginning in 2016. Coal is transported from the mine site in numerous ways, including rail, truck, barge or ship. The Partnership's coal terminals act as intermediaries between coal producers and coal end users by providing transloading, storage and mixing services. The Partnership does not take possession of coal in its coal logistics business, but instead earns revenue by providing coal handling and/or mixing services to its customers on a fee per ton basis. Mixing and/or handling services are provided to steel, coke (including some of our domestic cokemaking facilities), electric utility and coal producing customers.

31

The financial performance of the Partnership's coal logistics business is substantially dependent upon a limited number of customers. The Partnership's CMT customers are impacted by seaborne export market dynamics. Fluctuations in the benchmark price for coal delivery into northwest Europe, as referenced in the Argus/McCloskey's Coal Price Index report ("API2 index price"), contribute to the Partnership's customers' decisions to place tons into the export market and thus impact transloading volumes through the Partnership's terminal facility. The Partnership's KRT terminals are primarily impacted by the domestic coal markets in which its customers operate and generally benefit from extreme weather conditions.

The Partnership's coal logistics customers have experienced more stable thermal coal prices, both API2 and domestic,during the first half of 2017 as well as significant increases to these prices in 2017 as compared to lows in early 2016.Additionally, metallurgical coal export prices have significantly increased during the first half of 2017 as compared to the prior year period. As a result, tons handled by the Coal Logistics segment have increased and improved its financial performance in the first half of 2017 as compared to the first half of 2016.

Our consolidated financial statements include SunCoke Energy Partners, L.P. (the "Partnership"), a publicly-traded master limited partnership. As of June 30, 2017, we owned the general partner of the Partnership, which consists of a 2.0 percent ownership interest and incentive distribution rights ("IDR"), and owned a 57.0 percent limited partner interest in the Partnership. The remaining 41.0 percent interest in the Partnership was held by public unitholders.

Incorporated in Delaware in 2010 and headquartered in Lisle, Illinois, we became a publicly-traded company in 2011 and our stock is listed on the New York Stock Exchange (“NYSE”) under the symbol “SXC.”

Recent Developments

• Termination of the Proposed Simplification Transaction

In April 2017, the Company announced the termination of discussions with the Conflicts Committee of the Board of Directors of the Partnership regarding our proposal to acquire all of the Partnership’s common units not already owned by the Company ("Simplification Transaction"), announced on October 31, 2016. The Conflicts Committee and its independent advisors reviewed the proposal made by the Company and had several discussions with the Company regarding the potential transaction. At this time, the parties determined that they will not be able to reach an agreement and have therefore terminated discussions regarding the proposed Simplification Transaction.

The Company and the Partnership recorded $1.5 million and $0.3 million of transaction costs related to the proposed Simplification Transaction in selling, general and administrative expenses on the Consolidated Statement of Operations during the six months ended June 30, 2017 and the year ended December 31, 2016, respectively.

The Partnership received $620.6 million of proceeds, net of an original issue discount of $9.4 million, from the issuance of the 7.5 percent 2025 Partnership Notes and $100.0 million of proceeds from borrowings under the Partnership's amended and restated credit facility. The Partnership used these proceeds to purchase and redeem all of its 7.375 percent 2020 Partnership Notes, including principal of$463.0 million and a premium of $18.7 million, to repay the $50.0 million outstanding on the Partnership Term Loan and to repay $172.0 million on the Partnership Revolver. In connection with the debt issuance, the Company and the Partnership incurred debt issuance costs of $15.9 million, which were included in long-term debt and financing obligation on the Consolidated Balance Sheets as of June 30, 2017.

As a result of the debt refinancing, the three and six months ended June 30, 2017 included a loss on extinguishment of debt on the Consolidated Statement of Operations of $20.2 million and $20.3 million,respectively, which consisted primarily of the premium paid of $18.7 million.

The Partnership intends to repay the outstanding balance on the Partnership's Promissory Note of $112.6 million in August 2017, primarily using available borrowing capacity under the Partnership Revolver. The Partnership anticipates annualized interest expense, net to increase by approximately $8 million, which includes approximately $6 million of cash interest, net of $3 million of interest savings from the anticipated refinancing of the Partnership Promissory Note in August 2017, and $2 million of amortization of debt issuance costs and discounts. See Note 6 to our consolidated financial statements for further details.

During the three and six months ended June 30, 2016, the Partnership repurchased $17.1 million and $69.9 million, respectively, of 2020 Partnership Notes, which resulted in a gain on extinguishment of debt of $3.5 million and $23.9 million, respectively.

• IRS Final Regulations on Qualifying Income. In January 2017, the Internal Revenue Service ("IRS") announced its decision to exclude cokemaking as a qualifying income generating activity in its final regulations (the "Final Regulations") issued under section 7704(d)(1)(E) of the Internal Revenue Code relating to the qualifying income exception for publicly traded partnerships. However, the Final Regulations include a transition period for activities that were reasonably interpreted to be qualifying income and carried on by publicly traded partnerships prior to the Final Regulations. The Partnership previously received a will-level opinion from its counsel, Vinson & Elkins LLP, that the Partnership's cokemaking operations generated qualifying income prior to the Final Regulations. Therefore, the Partnership believes it had a reasonable basis to conclude its cokemaking operations were considered qualifying income before the issuance of the new regulations and as such expects to maintain its treatment as a partnership through the transition period. Cokemaking entities in the Partnership will become taxable as corporations on January 1, 2028, after the transition period ends.

As a result of the Final Regulations, the Partnership recorded deferred income tax expense of $148.6 million to set up its initial deferred income tax liability during the first quarter of 2017, primarily related to differences in the book and tax basis of fixed assets, which are expected to exist at the end of the 10-year transition period when the cokemaking operations become taxable.  As the Company consolidates the Partnership, the entire deferred income tax expense was recognized during the first quarter of 2017. However, the Company had already recorded $84.4 million of the deferred income tax liability in its financial statements related to the Company's share of the deferred tax liability for the book and tax differences in its investment in the Partnership. Therefore, the net impact to the Company’s deferred tax expense was $64.2 million during the six months ended June 30, 2017. This incremental tax impact is solely attributable to the Partnership’s public unitholders. As such, an equal reduction to noncontrolling interest was recorded. As a result, the Final Regulations have no impact to net income attributable to the Company.

• Terminated the Potential New Cokemaking Facility Project. We continue to have regular discussions with our customers regarding their respective long-term coke requirements. However, our ability to construct a new cokemaking facility, or enter into new commercial arrangements with our coke customers, is subject to our customers' decisions with respect to their own cokemaking assets, their outlook for their coke requirements and general domestic steel industry and market conditions. Our ongoing focus is to renew our existing customers' contracts in the upcoming years.

In 2014, we finalized the required permitting and engineering plan for a potential new cokemaking facility to be constructed in Kentucky. However, in June 2017, due to our focus on renewing our existing customer contracts and the lack of any long-term customer commitment for a majority of the facility's capacity, we decided to terminate the project. As a result, during the second quarter of 2017, the Company wrote-off previously capitalized engineering and land deposit costs of $5.3 million. During the second quarter of 2016, the Company

33

wrote-off expiring land deposits related to the project of $1.9 million. These costs were included in selling, general and administrative expenses on the Consolidated Statements of Operations.

• Jewell Coke's Reimbursable Coal Costs. The reimbursable coal component of our Jewell cokemaking facility is fixed annually for each calendar year based on the weighted-average contract price of third-party coal purchases at our Haverhill I cokemaking facility ("HHI Benchmark"). Historically, Jewell's actual coal costs have been higher than the HHI Benchmark, resulting in an under-recovery of coal costs at Jewell. During the three and six months ended June 30, 2017, we have narrowed the difference between the HHI Benchmark and Jewell's actual coal costs, lessening the under-recovery and improving Adjusted EBITDA by $1.0 million and $3.4 million as compared to the same prior year periods, respectively.

• Pass Through Coal Cost Under-Recovery. During the fourth quarter of 2016, as part of our ordinary course coal sourcing activities, Haverhill, Middletown and AK Steel each entered into arrangements with a coal supplier for 2017 fulfillment. As a result of unfulfilled coal supply commitments by this coal supplier, substitute coal suppliers are currently meeting the shortfall, resulting in a higher price. Presently, we are aggressively pursuing the coal supplier and sharing a portion of the increased coal cost differential with AK Steel, resulting in a negative impact to revenue and Adjusted EBITDA of $1.4 million and $2.8 million during the three and six months ended June 30, 2017, respectively. We expect this impact to lower revenue and Adjusted EBITDA by approximately $6 million for the year ended December 31, 2017.

• Coal Mining Business Divestiture and Impairment. In April 2016, the Company successfully disposed of its coal mining business to Revelation Energy, LLC ("Revelation"), who assumed substantially all of our remaining coal mining assets, mineral leases, real estate and a substantial portion of our mining reclamation obligations. Under the terms of the agreement, Revelation received $12.1 million from the Company to take ownership of the assets and liabilities during the second quarter of 2016. The Company paid an additional $0.7 million in the third quarter of 2016 to transfer certain retirement obligations to Revelation. During the three and six months ended June 30, 2016 the Company recognized total losses associated with this divestiture of $5.1 million and $14.7 million, respectively, which included a $10.7 million asset impairment charge recorded in the first quarter of 2016. Cost savings due to the absence of the coal mining business improved Adjusted EBITDA results by $0.3 million and $3.1 million during the three and six months ended June 30, 2017, respectively, as compared to the same prior year periods.

• Contingent Consideration. In connection with the CMT acquisition, the Partnership entered into a contingent consideration arrangement that requires the Partnership to make future payments to The Cline Group based on future volumes over a specified threshold, price, and contract renewals. During the first quarter of 2016, the Partnership amended the contingent consideration terms with The Cline Group, which resulted in a $3.7 million gain recognized as a reduction to costs of products sold and operating expenses on the Consolidated Statements of Operations during the six months ended June 30, 2016.

(1) See year-over-year changes described in "Items Impacting Comparability."

Sales and Other Operating Revenue. Sales and other operating revenue increased for both the three and six months ended June 30, 2017 compared to the same prior year periods. These increases were primarily due to the pass-through of higher coal prices in our Domestic Coke segment as well as higher sales volumes in our Coal Logistics segment. These increases were partially offset by lower sales volumes at our Domestic Coke segment, driven by oven rebuilds at our Indiana Harbor cokemaking facility.

Costs of Products Sold and Operating Expenses. Costs of products sold and operating expenses increased for both the three and six months ended June 30, 2017 compared to the same prior year periods. These increases were primarily due to higher coal costs associated with higher coal prices in our Domestic Coke segment, discussed above, as well as the absence of the $3.7 million gain from the contingent consideration adjustment recorded in the first quarter of 2016, previously discussed in "Items Impacting Comparability."

Selling, General and Administrative Expenses. Selling, general and administrative expense during the three and six months ended June 30, 2017 included a write-off of costs associated with the termination of our project for a potential new cokemaking facility of $5.3 million, previously discussed in "Items Impacting Comparability." The three and six months ended June 30, 2016 included a $1.9 million write-off related to expiring land deposits related to the project, a $1.4 million write-off of a receivable related to 2015 spot coke sales to Essar Algoma and higher professional fees. Additionally, the Company incurred costs to resolve certain legal matters during the six months ended June 30, 2016.

Depreciation and Amortization Expense. The increase in depreciation and amortization expense during the three and six months ended June 30, 2017 compared to the same prior year periods was primarily the result of revisions in 2016 to the remaining useful lives of our Indiana Harbor cokemaking ovens due to higher than expected oven degradation, which resulted in additional depreciation of $4.7 million, or $0.07 per common share, during the three months ended June 30, 2017, and $9.5 million, or $0.15 per common share, during the six months ended June 30, 2017.

Interest Expense, Net. The increase in interest expense, net during the three and six months ended June 30, 2017 compared to the same prior year periods was primarily due to higher interest rates on the 2025 Partnership Notes issued in May 2017 previously

35

discussed in "Items Impacting Comparability," as well as lower capitalized interest during the three and six months ended June 30, 2017 as compared to the prior year period.

Income Taxes. Income tax expense increased during the three months ended June 30, 2017, as compared to the same prior year period, driven primarily by a valuation allowance of $4.9 million included in income tax expense as a result of changes in future state allocation assumptions partially offset by a state income tax benefit of $2.5 million related to the filing of an amended state tax return. Income tax expense during the six months ended June 30, 2017 also included the impacts of the IRS Final Regulations previously discussed in "Items Impacting Comparability."

Noncontrolling Interest. Net (loss) income attributable to noncontrolling interest represents the common public unitholders’ interest in SunCoke Energy Partners, L.P. as well as a 14.8 percent third-party interest in our Indiana Harbor cokemaking facility. The following table provides details into net (loss) income attributable to noncontrolling interest.

	Three months ended June 30,								Six months ended June 30,
	2017			2016		Increase (Decrease)			2017			2016		Increase (Decrease)
Net (loss) income attributable to the Partnership's common public unitholders'(1)(2)	$	(6.2	)	$	5.4	$	(11.6	)	$	(63.8	)	$	21.9	$	(85.7	)
Net (loss) income attributable to third-party interest in our Indiana Harbor cokemaking facility(3)	(1.1		)	0.2		(1.3		)	(2.2		)	0.4		(2.6		)
Net (loss) income attributable to noncontrolling interest	$	(7.3	)	$	5.6	$	(12.9	)	$	(66.0	)	$	22.3	$	(88.3	)

(1) The decrease during the three months ended June 30, 2017 as compared to the same prior year period was primarily due to the Partnership's loss on extinguishment of debt during the second quarter of 2017 as compared to the Partnership's gain on extinguishment of debt during the second quarter of 2016.

(2) The decrease during the six months ended June 30, 2017 as compared to the same prior year period was primarily due to the impact of the IRS Final Regulations previously described in "Recent Developments" and the Partnership's loss on extinguishment of debt during the six months ended June 30, 2017 as compared to the Partnership's gain on extinguishment of debt during the six months ended June 30, 2016.

(3) The decrease during the three and six months ended June 30, 2017 as compared to the same prior year period was primarily driven by lower volumes and higher operating and maintenance spending as a result of ovens out of service associated with the oven rebuild project.

Results of Reportable Business Segments

We report our business results through three segments:

• Domestic Coke consists of our Jewell, Indiana Harbor, Haverhill, Granite City and Middletown cokemaking and heat recovery operations located in Vansant, Virginia; East Chicago, Indiana; Franklin Furnace, Ohio; Granite City, Illinois; and Middletown, Ohio, respectively.

• Brazil Coke consists of our operations in Vitória, Brazil, where we operate a cokemaking facility, ArcelorMittal Brazil, for a Brazilian subsidiary of ArcelorMittal S.A.;

• Coal Logistics consists of CMT, KRT, Lake Terminal, and DRT coal handling and/or mixing service operations in Convent, Louisiana; Ceredo and Belle, West Virginia; East Chicago, Indiana; and Vansant, Virginia, respectively. Lake Terminal and DRT are located adjacent to our Indiana Harbor and Jewell cokemaking facilities, respectively

The operations of each of our segments are described at the beginning of the MD&A.

Corporate expenses that can be identified with a segment have been included in determining segment results. The remainder is included in Corporate and Other, including activity from our legacy coal mining business, which was historically presented as a reportable segment. Prior year periods have been recasted to reflect current presentation.

Management believes Adjusted EBITDA is an important measure of operating performance and liquidity, which is used as the primary basis for the chief operating decision maker to evaluate the performance of each of our reportable segments. Adjusted EBITDA should not be considered a substitute for the reported results prepared in accordance with GAAP. See Note 14 to our consolidated financial statements.

Analysis of Segment Results

Domestic Coke

The following table explains year-over-year changes in the Domestic Coke segment's sales and other operating revenues and Adjusted EBITDA results:

	Three months ended June 30, 2017 vs. 2016						Six months ended June 30, 2017 vs. 2016
	Sales and other operating revenue			Adjusted EBITDA			Sales and other operating revenue			Adjusted EBITDA
	(Dollars in millions)
Prior year period	$	274.0		$	51.0		$	563.0		$	105.3
Indiana Harbor(1)	(0.1		)	(4.7		)	(11.6		)	(9.6		)
Volumes(2)	(0.9		)	0.9			(3.5		)	1.5
Coal cost recovery and yields(3)	24.5			0.8			29.8			1.9
Operating and maintenance costs(4)	0.5			(3.0		)	—			(3.6		)
Energy and other(5)	(1.5		)	(1.0		)	(2.5		)	(1.8		)
Current year period	$	296.5		$	44.0		$	575.2		$	93.7

(1) Indiana Harbor results were negatively impacted by increased operating and maintenance spending and lower volumes of 30 thousand and 66 thousand tons in the three months and six months ended June 30, 2017, respectively, as compared to the prior year periods due to the ongoing oven rebuild initiative. Indiana Harbor revenues in the three months ended June 30, 2017 benefited from approximately $7 million of higher pass-through coal costs. Indiana Harbor revenues in the six months ended June 30, 2017 benefited from approximately $5 million of higher pass-through coal costs as compared to the prior year period as fluctuating coal prices resulted in sales of lower cost inventory during the first quarter of 2017 as compared to the first quarter of 2016.

(2) We delivered lower volumes to AK Steel in 2017 compared to 2016, but received make-whole payments based on the terms of our long-term, take-or-pay contract. As such this reduction in volumes did not impact the period-over-period change in Adjusted EBITDA.

(3) The increase in revenues was primarily driven by the pass-through of higher coal prices. Additionally, the under-recovery of coal costs at Jewell previously discussed in "Items Impacting Comparability" was less significant during the three and six months ended June 30, 2017 as compared to the same prior year periods, increasing revenues $7.4 million and $14.9 million, respectively, and increasing Adjusted EBITDA by $1.0 million and $3.4 million, respectively. As a result of unfulfilled coal supply commitments by our coal supplier, substitute coal suppliers are currently meeting the shortfall, resulting in higher coal prices as previously discussed in "Items Impacting Comparability." These higher coal prices decreased both revenues and Adjusted EBITDA by $1.4 million for the three months ended June 30, 2017 and $2.8 million for the six months ended June 30, 2017.

(4) The decrease in Adjusted EBITDA was due to slightly higher costs across the fleet, including costs of $0.6 million associated with the planned outage at the Granite City facility in the second quarter.

(5) The decrease in both revenues and Adjusted EBITDA was driven by lower energy sales as a result of the planned outage as discussed above. Adjusted EBITDA was favorably impacted by the absence of the second quarter 2016 write-off of a $1.4 million receivable related to 2015 spot coke sales to Essar Algoma.

Coal Logistics

The following table explains year-over-year changes in the Coal Logistics segment's sales and other operating revenues and Adjusted EBITDA results:

	Three months ended June 30, 2017 vs. 2016						Six months ended June 30, 2017 vs. 2016
	Sales and other operating revenue, inclusive of intersegment sales			Adjusted EBITDA			Sales and other operating revenue, inclusive of intersegment sales			Adjusted EBITDA
	(Dollars in millions)
Prior year period	$	16.5		$	5.4		$	34.7		$	11.3
Transloading volumes(1)	4.6			4.3			11.6			11.2
Price/margin impact of mix in transloading services	(0.3		)	(0.3		)	(0.1		)	(0.1		)
Operating and maintenance costs and other	0.5			0.6			0.4			0.7
Current year period	$	21.3		$	10.0		$	46.6		$	23.1

(1) The increase in revenues and Adjusted EBITDA during the three and six months ended June 30, 2017 was the result of 965 thousand and 2,369 thousand of higher tons handled as compared to the prior year periods, respectively, primarily at CMT.

Brazil

Three Months Ended June 30, 2017 compared to Three Months Ended June 30, 2016

Sales and other operating revenue increased$3.2 million, or 43.8 percent, to $10.5 million for the three months ended June 30, 2017 compared to $7.3 million for the same period of 2016. The increase in revenues was primarily due to an incremental $1.3 million in licensing fees related to the addition of certain patents to our existing intellectual property licensing agreement as well as favorable foreign currency adjustments compared to the same prior year period, which increased revenues $0.6 million. The remaining increase of $1.3 million was driven by higher reimbursable operating and maintenance costs of $0.7 million as well as higher coke sales volumes and production bonuses received from our customer in the current year for meeting certain volume targets not met in the prior year.

Adjusted EBITDA increased$2.1 million, or 87.5 percent, to $4.5 million for the three months ended June 30, 2017 compared to $2.4 million for the same period of 2016. The increase in Adjusted EBITDA was the result of the $1.3 million in incremental licensing fees, favorable foreign currency adjustments and higher coke sales volumes and production bonuses as discussed above.

Six Months Ended June 30, 2017 compared to Six Months Ended June 30, 2016

Sales and other operating revenue increased$6.3 million, or 42.0 percent, to $21.3 million for the six months ended June 30, 2017 compared to $15.0 million for the same period of 2016. The increase in revenues was primarily due to an incremental $2.6 million in licensing fees as well as $1.6 million of favorable foreign currency adjustments compared to the same prior year period. Additionally, revenues increased $1.2 million due to higher volumes, including production bonuses received from our customer in the current year for meeting certain volume targets not met in the prior year. The remaining increase of $0.9 million was primarily due to higher reimbursable operating and maintenance costs.

Adjusted EBITDA increased$4.2 million, or 89.4 percent, to $8.9 million for the six months ended June 30, 2017 compared to $4.7 million for the same period of 2016. The increase in Adjusted EBITDA was primarily the result of the $2.6 million in incremental licensing fees. The remaining increase in Adjusted EBITDA of $1.6 million was primarily driven by higher volumes as described above.

Corporate and Other

Three Months Ended June 30, 2017 compared to Three Months Ended June 30, 2016

Corporate and other revenues, inclusive of intersegment sales, were $0.8 million for the three months ended June 30, 2016 and primarily represented revenues from our legacy coal mining business, which was disposed of in April 2016.

Corporate and other Adjusted EBITDA results, which include activity from our legacy coal mining business, was a loss of $11.0 million in the second quarter 2017, an improvement of $1.3 million compared to the second quarter 2016. The improvement was partly driven by lower legal costs in the current year period.

39

Six Months Ended June 30, 2017 compared to Six Months Ended June 30, 2016

Corporate and other revenues, inclusive of intersegment sales, were $23.5 million for the six months ended June 30, 2016 and primarily represented revenues from our legacy coal mining business, which was disposed of in April 2016.

Corporate and other Adjusted EBITDA results, which include activity from our legacy coal mining business, was a loss of $22.6 million for the six months ended June 30, 2017, an improvement of $8.4 million compared to the same period of 2016. The improvement includes a $3.1 million period-over-period benefit associated with the absence of our coal mining business, which was disposed of in April 2016. The remaining improvement was driven by the absence of costs incurred to resolve certain legal matters in the prior year period as well as favorable period-over-period impact of $0.7 million of mark-to-market adjustments in deferred compensation and $1.0 million of lower employee related costs compared the prior year period.

Liquidity and Capital Resources

Our primary liquidity needs are to finance the replacement of partially or fully depreciated assets and other capital expenditures, service our debt, fund investments, fund working capital and maintain cash reserves. Our sources of liquidity include cash generated from operations, borrowings under our revolving credit facility and, from time to time, debt and equity offerings. We believe our current resources are sufficient to meet our working capital requirements for our current business for the foreseeable future. The Company and Partnership may be required to access the capital markets for funding related to the maturities of our long-term borrowings in the future. As of June 30, 2017, together with the Partnership, we had $136.7 million of cash and cash equivalents and $253.8 million of borrowing availability under our credit facilities.

Debt Refinancing

During the second quarter of 2017, the Partnership refinanced its debt obligations. The Partnership received $620.6 million of proceeds, net of an original issue discount of $9.4 million, from the issuance of the 7.5 percent 2025 Partnership Notes and $100.0 million of proceeds from borrowings under the Partnership's amended and restated credit facility. The Partnership also increased its capacity to $285.0 million and extended its maturity date to 2022 under the Partnership Revolver. Additionally, the Company extended its maturity date to May 2022 and reduced its capacity to $100.0 million under the Revolving Facility. In connection with the debt issuance, the Company and the Partnership incurred debt issuance costs of $15.9 million, which were included in long-term debt and financing obligation on the Consolidated Balance Sheets as of June 30, 2017.

During the second quarter of 2017, the Partnership used the proceeds, described above, to purchase and redeem all of its 2020 Partnership Notes, including principal of $463.0 million and a premium of $18.7 million, to repay the $50.0 million outstanding on the Partnership Term Loan and to repay $172.0 million on the Partnership Revolver. The Partnership also paid $11.0 million of accrued interest to redeem all of its 2020 Partnership Notes.

The Partnership intends to repay the outstanding balance on the Partnership's Promissory Note of $112.6 million in August 2017, primarily using available borrowing capacity under the Partnership Revolver. The Partnership anticipates annualized interest expense, net to increase by approximately $8 million, which includes approximately $6 million of cash interest, net of $3 million of interest savings from the anticipated refinancing of the Partnership Promissory Note in August 2017, and $2 million of amortization of debt issuance costs and discounts. See Note 6 to our consolidated financial statements for further details.

Covenants

As of June 30, 2017, the Company and the Partnership were in compliance with all applicable debt covenants. We do not anticipate violation of these covenants nor do we anticipate that any of these covenants will restrict our operations or our ability to obtain additional financing. See Note 6 to the consolidated financial statements for details on debt covenants.

Credit Rating

In May 2017, Moody's Investor Services ("Moody's") upgraded the Company's corporate family rating to B1 from B2, in connection with the refinancing of the Partnership's capital structure. The rating upgrade reflects the improved steel market fundamentals and the strengthened financial position of our customers as well as de-leveraging undertaken by the Company and Partnership in the past 24 months.

Distributions

OnJuly 17, 2017, the Partnership's Board of Directors declared a quarterly cash distribution of $0.5940 per unit. This distribution will be paid on September 1, 2017 to unitholders of record on August 15, 2017.

40

Partnership Public Unit Purchase Program

On April 17, 2017, the Company's Board of Directors authorized a program for the Company to purchase outstanding Partnership public units at any time and from time to time in the open market, through privately negotiated transactions, block transactions, or otherwise for a total aggregate cost to the Company not to exceed $50.0 million. During the second quarter of 2017, the Company purchased 1,460,404, or approximately 7 percent, of outstanding Partnership public units in the open market for a total cost of $24.6 million, leaving a remaining public unit purchase program balance of $25.4 million as of June 30, 2017. In July 2017, the Company's Board of Directors authorized the Company to purchase an incremental $50.0 million of Partnership public units in the open market. Subsequent to June 30, 2017, the Company purchased an additional 131,274 of outstanding Partnership public units in the open market for a total cost of $2.3 million, leaving a remaining public unit purchase program balance of $73.1 million as of July 26, 2017.

Cash Flow Summary

The following table sets forth a summary of the net cash provided by (used in) operating, investing and financing activities for the six months ended June 30, 2017 and 2016:

	Six Months Ended June 30,
	2017			2016
	(Dollars in millions)
Net cash provided by operating activities	$	54.4		$	121.5
Net cash used in investing activities	(1.8		)	(24.3		)
Net cash used in financing activities	(49.9		)	(112.6		)
Net increase (decrease) in cash and cash equivalents	$	2.7		$	(15.4	)

Cash Flows from Operating Activities

Net cash provided by operating activities decreased by $67.1 million to $54.4 million as compared to the corresponding prior year period. The decrease in operating cash flows is primarily driven by the unfavorable year-over-year change in primary working capital, which is comprised of accounts receivable, inventories and accounts payable, of approximately $40 million due mostly to fluctuating coal prices and inventory levels. Further contributing to the decrease in operating cash flows were higher compensation-related benefit payments of approximately $5.0 million as compared to the prior year period.  Income tax payments, net of $3.1 million in the current period compared to income tax refunds, net of $2.2 million in the prior year period also drove an unfavorable comparison.

Additionally, as a result of the current period debt refinancing, the Partnership made additional interest payments of $11.0 million during the second quarter of 2017 as interest payments normally made in the third quarter were accelerated in conjunction with the refinancing. These accelerated payments were partially offset by $3.9 million of lower interest payments made in the current year period as compared to the prior year period as debt repurchases throughout 2016 lowered outstanding debt balances. The remaining decrease was primarily due to the impacts of the oven rebuild project at Indiana Harbor and the planned outage at Granite City during the six months ended June 30, 2017 as compared to the same prior year period.

Cash Flows from Investing Activities

Net cash used in investing activities decreased by $22.5 million to $1.8 million as compared to $24.3 million in the corresponding period of 2016. The decrease was driven by the $20.5 million return of the Brazilian investment collected during the first half of 2017. The prior year period also included a $12.1 million payment related to the divestiture of the coal mining business partially offset by an amendment to an agreement with The Cline Group, which unrestricted $6.0 million of previously restricted cash and relieved the Partnership of any obligation to repay these amounts to The Cline Group. See "Capital Requirements and Expenditures" for details on total capital expenditures during the first half of 2017 and 2016.

Cash Flows from Financing Activities

Net cash used in financing activities was $49.9 million for the six months ended June 30, 2017. In the first half of 2017, the Partnership received gross proceeds of $620.6 million from the issuance of the 2025 Partnership Senior Notes and $100.0 million from the Partnership Revolver under its amended and restated credit facility. The proceeds received were used primarily to repay $532.2 million of long-term debt, to repay $172.0 million on the Partnership Revolver and pay $15.6 million of debt issuance costs related to the debt refinancing.

Additionally, the Company paid $24.6 million to acquire outstanding Partnership public units and the Partnership paid distributions of $24.6 million to its public unitholders during the first half of 2017.

41

Net cash used in financing activities was $112.6 million for the six months ended June 30, 2016. In the first half of 2016, we repaid $87.4 million of outstanding debt obligations, including $47.0 million of Partnership Notes and $40.4 million of the Company's Revolving Facility, and paid distributions of $24.7 million to its public unitholders.

Capital Requirements and Expenditures

Our operations are capital intensive, requiring significant investment to upgrade or enhance existing operations and to meet environmental and operational regulations. The level of future capital expenditures will depend on various factors, including market conditions and customer requirements, and may differ from current or anticipated levels. Material changes in capital expenditure levels may impact financial results, including but not limited to the amount of depreciation, interest expense and repair and maintenance expense.

Our capital requirements have consisted, and are expected to consist, primarily of:

• Ongoing capital expenditures required to maintain equipment reliability, the integrity and safety of our coke ovens and steam generators and to comply with environmental regulations. Ongoing capital expenditures are made to replace partially or fully depreciated assets in order to maintain the existing operating capacity of the assets and/or to extend their useful lives and also include new equipment that improves the efficiency, reliability or effectiveness of existing assets. Ongoing capital expenditures do not include normal repairs and maintenance expenses, which are expensed as incurred;

• Environmental remediation project expenditures required to implement design changes to ensure that our existing facilities operate in accordance with existing environmental permits; and

• Expansion capital expenditures to acquire and/or construct complementary assets to grow our business and to expand existing facilities as well as capital expenditures made to enable the renewal of a coke sales agreement and on which we expect to earn a reasonable return.

The following table summarizes ongoing, environmental remediation projects and expansion capital expenditures:

	Six Months Ended June 30,
	2017		2016
	(Dollars in millions)
Ongoing capital	$	13.6	$	12.0
Environmental remediation projects(1)	8.4		5.1
Expansion capital:
CMT(2)	0.1		10.7
Other capital expansion	0.3		2.4
Total capital expenditures	$	22.4	$	30.2

(1) Includes $0.3 million and $1.4 million of capitalized interest in connection with the environmental remediation projects during the six months ended June 30, 2017 and 2016, respectively.

(2) Represents capital expenditures of $9.5 million for the ship loader expansion project funded with cash withheld in conjunction with the acquisition of CMT and $1.2 capitalized interest for the six months ended June 30, 2016.

In 2017, we expect our capital expenditures to be approximately $80 million, which is comprised of the following:

• Total ongoing capital expenditures of approximately $52 million, of which approximately $17 million will be spent at the Partnership and approximately $20 million to $25 million will be spent on the 2017 Indiana Harbor oven rebuild project;

• Total capital expenditures on environmental remediation projects of approximately $25 million, all of which will be spent at the Partnership; and

• Total expansion capital of approximately $3 million in our Coal Logistics segment.

We expect that capital expenditures will remain at this level in 2018, including capital expenditures of approximately $25 million at the Partnership related to the remediation project.

We anticipate spending a total of between approximately $140 million and $145 million in environmental remediation projects to comply with the expected terms of the consent decree at our Haverhill and Granite City cokemaking operations. We have spent approximately $101 million related to these projects since 2012. The remaining capital is expected to be spent

42

through the first quarter of 2019. A portion of the proceeds from the Partnership's initial public offering and subsequent dropdowns are expected to be used to fund $119 million of these environmental remediation projects. Pursuant to the omnibus agreement, any amounts that the Partnership spends on these projects in excess of the $119 million will be reimbursed by the Company.

Off-Balance Sheet Arrangements

We have letters of credit, operating leases and outstanding surety bonds to secure reclamation and other performance commitments. There have been no significant changes to these arrangements during the six months ended June 30, 2017. Please refer to SunCoke Energy, Inc.’s Annual Report on Form 10-K filed on February 16, 2017 for further disclosure of these arrangements. Other than these arrangements, the Company has not entered into any transactions, agreements or other contractual arrangements that would result in material off-balance sheet liabilities.

Critical Accounting Policies

There have been no significant changes to our accounting policies during the six months ended June 30, 2017. Please refer to SunCoke Energy, Inc.’s Annual Report on Form 10-K filed on February 16, 2017 for a summary of these policies.

Recent Accounting Standards

See Note 1 to our consolidated financial statements.

Non-GAAP Financial Measures

In addition to the GAAP results provided in this Quarterly Report on Form 10-Q, we have provided a non-GAAP financial measure, Adjusted EBITDA. Our management, as well as certain investors, use this non-GAAP measure to analyze our current and expected future financial performance and liquidity. This measure is not in accordance with, or a substitute for, GAAP and may be different from, or inconsistent with, non-GAAP financial measures used by other companies. See Note 14 in our consolidated financial statements for both the definition of Adjusted EBITDA and reconciliations from GAAP to the non-GAAP measurement for the three and six months ended June 30, 2017 and 2016, respectively. This reconciliation has been updated to reflect the impact of our debt refinancing activity.

Below is a reconciliation of 2017 Adjusted EBITDA guidance from its closest GAAP measures:

	2017
	Low			High
Net cash provided by operating activities	$	128		$	143
Subtract:
Depreciation and amortization expense	131			131
Deferred income tax expense	65			70
Changes in working capital and other	(27		)	(28		)
Loss on extinguishment of debt	20			20
Net loss	$	(61	)	$	(50	)
Add:
Depreciation and amortization expense	131			131
Interest expense, net	63			62
Loss on extinguishment of debt	20			20
Income tax expense	67			72
Adjusted EBITDA	$	220		$	235
Subtract: Adjusted EBITDA attributable to noncontrolling interests(1)	90			94
Adjusted EBITDA attributable to SunCoke Energy, Inc.	$	130		$	141

(1) Reflects non-controlling interest in Indiana Harbor and the portion of the Partnership owned by public unitholders.

Item 4. Controls and Procedures

Management’s Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) that are designed to ensure that information required to be disclosed in its reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms, and that such information is accumulated and communicated to the Company’s management, including the its Chief Executive Officer and Chief Financial Officer as appropriate, to allow timely decisions regarding required disclosure.

In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

The Company carried out an evaluation, under the supervision and with the participation of management, including its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of the end of the period covered by this report. Based on this evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures were effective as of the end of the period covered by this report.

Many legal and administrative proceedings are pending or may be brought against us arising out of our current and past operations, including matters related to commercial and tax disputes, product liability, employment claims, personal injury claims, premises-liability claims, allegations of exposures to toxic substances and general environmental claims. Although the ultimate outcome of these proceedings cannot be ascertained at this time, it is reasonably possible that some of them could be resolved unfavorably to us. Our management believes that any liabilities that may arise from such matters would not be material in relation to our business or our consolidated financial position, results of operations or cash flows at June 30, 2017.

Exhibit 95.1

SunCoke Energy, Inc.

Mine Safety Disclosures for the Quarter Ended June 30, 2017

We are committed to maintaining a safe work environment and working to ensure environmental compliance across all of our operations. The health and safety of our employees and limiting the impact to communities in which we operate are critical to our long-term success. We believe that we employ industry best practices and conduct routine training programs, equal to or greater than current regulatory requirements. We also focus additional effort and resources each day and each shift to help ensure that our employees are focused on safety. Furthermore, we employ a structured safety and environmental process that provides a robust framework for managing, monitoring and improving safety and environmental performance.

We have consistently operated our metallurgical coke operations within or near the top quartile for the U.S. Occupational Safety and Health Administration’s recordable injury rates as measured and reported by the American Coke and Coal Chemicals Institute. We also have worked to maintain low injury rates reportable to the U.S. Department of Labor’s Mine Safety and Health Administration (“MSHA”) and won the Sentinels of Safety award for 2008 from MSHA for having the mine with the most employee hours worked without experiencing a lost-time injury in that mine’s category.

The following table presents the information concerning mine safety violations and other regulatory matters that we are required to report in accordance with Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act. Whenever MSHA believes that a violation of the Federal Mine Safety and Health Act of 1977 (the “Mine Act”), any health or safety standard, or any regulation has occurred, it may issue a citation which describes the violation and fixes a time within which the operator must abate the violation. In these situations, MSHA typically proposes a civil penalty, or fine, that the operator is ordered to pay. In evaluating the following table regarding mine safety, investors should take into account factors such as: (1) the number of citations and orders will vary depending on the size of a coal mine, (2) the number of citations issued will vary from inspector to inspector, mine to mine and MSHA district to district and (3) citations and orders can be contested and appealed, and during that process are often reduced in severity and amount, and are sometimes dismissed.

The mine data retrieval system maintained by MSHA may show information that is different than what is provided in the table below. Any such difference may be attributed to the need to update that information on MSHA’s system or other factors. Orders and citations issued to independent contractors who work at our mine sites are not reported in the table below. All section references in the table below refer to provisions of the Mine Act.

Mine or Operating Name/MSHA Identification Number	Section 104 S&S Citations (#)(2)	Section 104(b) Orders (#)(3)	Section 104(d) Citations and Orders (#)(4)	Section 110(b)(2) Violations (#)(5)	Section 107(a) Orders (#)(6)	Total Dollar Value of MSHA Assessments Proposed ($)(7)	Total Number of Mining Related Fatalities (#)	Received Notice of Pattern of Violations Under Section 104(e) (yes/no)(8)	Received Notice of Potential to Have Pattern Under Section 104(e) (yes/no)(9)	Legal Actions Pending as of Last Day of Period (#)(10)(11)	Legal Actions Initiated During Period (#)(12)	Legal Actions Resolved During Period (#)(13)

(1) The table does not include the following: (i) facilities which have been idle or closed unless they received a citation or order issued by MSHA, (ii) permitted mining sites where we have not begun operations or (iii) mines that are operated on our behalf by contractors who hold the MSHA numbers and have the MSHA liabilities.

(2) Alleged violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a coal or other mine safety or health hazard.

(3) Alleged failures to totally abate a citation within the period of time specified in the citation.

(4) Alleged unwarrantable failure (i.e., aggravated conduct constituting more than ordinary negligence) to comply with a mining safety standard or regulation.

(5) Alleged flagrant violations issued.

(6) Alleged conditions or practices which could reasonably be expected to cause death or serious physical harm before such condition or practice can be abated.

(7) Amounts shown include assessments proposed during the quarter ended June 30, 2017and do not necessarily relate to the citations or orders reflected in this table. Assessments for citations or orders reflected in this table may be proposed by MSHA after June 30, 2017.

(8) Alleged pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of coal or other mine health or safety hazards.

(9) Alleged potential to have a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of coal or other mine health or safety hazards.

(10) This number reflects legal proceedings which remain pending before the Federal Mine Safety and Health Review Commission (the “FMSHRC”) as of June 30, 2017. The pending legal actions may relate to the citations or orders issued by MSHA during the reporting period or to citations or orders issued in prior periods. The FMSHRC has jurisdiction to hear not only challenges to citations, orders, and penalties but also certain complaints by miners. The number of “pending legal actions” reported here reflects the number of contested citations, orders, penalties or complaints which remain pending as of June 30, 2017.

(11) The legal proceedings reflected in this column of the table are categorized as follows in accordance with the categories established in the Procedural Rules of the FMSHRC:

Mine or Operating Name/MSHA Identification Number	Contests of Citations and Orders (#)	Contests of Proposed Penalties (#)	Complaints for Compensation (#)	Complaints for Discharge, Discrimination or Interference Under Section 105 (#)	Applications for Temporary Relief (#)	Appeals of Judges’ Decisions or Orders (#)

(12) This number reflects legal proceedings initiated before the FMSHRC during the quarter ended June 30, 2017. The number of “initiated legal actions” reported here may not have remained pending as of June 30, 2017.

(13) This number reflects legal proceedings before the FMSHRC that were resolved during the quarter ended June 30, 2017.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

General

1. General

Description of Business

SunCoke Energy, Inc. (“SunCoke Energy,” “Company,” "we," "our" and "us") is an independent owner and operator of five cokemaking facilities in the United States ("U.S."), which consists of our Haverhill Coke Company LLC ("Haverhill"), Middletown Coke Company, LLC ("Middletown"), Gateway Energy and Coke Company, LLC ("Granite City"), Jewell Coke Company, L.P. ("Jewell") and Indiana Harbor Coke Company ("Indiana Harbor") cokemaking facilities. Internationally, we operate a cokemaking facility in Brazil. We hold a 49 percent investment in a cokemaking joint venture with VISA Steel Limited in India ("VISA SunCoke"), which was fully impaired in 2015, and consequently, beginning in the fourth quarter of 2015, we no longer included our share of VISA SunCoke in our financial results.

Additionally, we own and operate a coal logistics business, which provides coal handling and/or mixing services to third-party customers as well as to our own cokemaking facilities. Our coal logistics business consists of Convent Marine Terminal ("CMT"), Kanawha River Terminals, LLC ("KRT"), SunCoke Lake Terminal, LLC ("Lake Terminal") and Dismal River Terminal, LLC ("DRT").

Our consolidated financial statements include SunCoke Energy Partners, L.P. (the "Partnership"), a publicly-traded partnership. At June 30, 2017, we owned the general partner of the Partnership, which consists of a 2.0 percent ownership interest and incentive distribution rights, and owned a 57.0 percent limited partner interest in the Partnership. The remaining 41.0 percent interest in the Partnership was held by public unitholders. SunCoke is considered the primary beneficiary of the Partnership as it has the power to direct the activities that most significantly impact the Partnership's economic performance.

Until April 2016, when the business was disposed of, we also controlled coal mining operations in Virginia and West Virginia.

Incorporated in Delaware in 2010 and headquartered in Lisle, Illinois, we became a publicly-traded company in 2011 and our stock is listed on the New York Stock Exchange (“NYSE”) under the symbol “SXC.”

Basis of Presentation

The accompanying unaudited consolidated financial statements included herein have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim reporting. Certain information and disclosures normally included in financial statements have been omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In management’s opinion, the financial statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair presentation of the results of operations, financial position and cash flows for the periods presented. The results of operations for the periods ended June 30, 2017 are not necessarily indicative of the operating results expected for the entire year. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016.

New Accounting Pronouncements

In May 2014, Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Subsequently, the FASB has issued various ASUs to provide further clarification around certain aspects of ASC 606. This standard will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and early adoption is permitted on a limited basis. Our implementation team has gained an understanding of the standard’s revenue recognition model and is completing the analysis and documentation of our contract details for impacts under the new revenue recognition model. Based on the current status of our assessment, we expect the timing of our revenue recognition to generally remain the same under the new standard on an annual basis. Deferred revenue at Convent Marine Terminal may be recognized on a more accelerated basis during quarterly periods within the year based on facts and circumstances considered at each quarter under the new guidance. The Company expects to adopt this standard on January 1, 2018 using the modified retrospective method.

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires lessees to be recognized as assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. It is effective for annual and interim periods in fiscal years beginning after December 15, 2018, with early adoption permitted. The standard requires the use of a modified retrospective transition method. A multi-disciplined implementation team has gained an understanding of the accounting and disclosure provisions of the standard and is in the process of analyzing the impacts to our business, including the development of new accounting processes to account for our leases and support the required disclosures. While we are still evaluating the impact of adopting this standard, we expect that upon adoption the right-of-use assets and lease liabilities, such as various plant equipment rentals and the lease of our corporate office space, will increase the reported assets and liabilities on our Consolidated Balance Sheets. The Company expects to adopt this standard on January 1, 2019.

Goodwill and Other Intangible Assets

3. Goodwill and Other Intangible Assets

Goodwill, which represents the excess of the purchase price over the fair value of net assets acquired, is tested for impairment as of October 1 of each year, or when events occur or circumstances change that would, more likely than not, reduce the fair value of a reporting unit to below its carrying value. Goodwill allocated to our Domestic Coke and Coal Logistics segments was $3.4 million and $73.5 million at both June 30, 2017 and December 31, 2016, respectively.

The components of intangible assets were as follows:

		June 30, 2017						December 31, 2016
	Weighted - Average Remaining Amortization Years	Gross Carrying Amount		Accumulated Amortization		Net		Gross Carrying Amount		Accumulated Amortization		Net
		(Dollars in millions)
Customer contracts	5	$	31.7	$	11.8	$	19.9	$	31.7	$	9.9	$	21.8
Customer relationships	14	28.7		4.7		24.0		28.7		3.8		24.9

Total		$	200.6	$	27.1	$	173.5	$	200.6	$	21.6	$	179.0

The permits above represent the environmental and operational permits required to operate a coal export terminal in accordance with the United States Environmental Protection Agency and other regulatory bodies. Intangible assets are amortized over their useful lives in a manner that reflects the pattern in which the economic benefit of the asset is consumed. The permits’ useful lives were estimated to be 27 years at acquisition based on the expected useful life of the significant operating equipment at the facility. These permits have an average remaining renewal term of approximately 3.9 years. The permits were renewed regularly prior to our acquisition of CMT. We also have historical experience of renewing and extending similar arrangements at our other facilities and intend to continue to renew our permits as they come up for renewal for the foreseeable future.

Total amortization expense for intangible assets subject to amortization was $2.8 million and $5.5 million for the three and six months ended June 30, 2017, respectively, and $2.9 million and $5.6 million for the three and six months ended June 30, 2016, respectively.

Income Taxes

4. Income Taxes

At the end of each interim period, we make our best estimate of the effective tax rate expected to be applicable for the full fiscal year and the impact of discrete items, if any, and adjust the rate as necessary.

The Company recorded income tax expense of $4.7 million and $70.9 million during the three and six months ended June 30, 2017, respectively. Income tax expense during the three months ended June 30, 2017 was driven primarily by a valuation allowance of $4.9 million recorded as a result of changes in future state allocation assumptions partially offset by a state income tax benefit of $2.5 million related to the filing of an amended state tax return. Income tax expense during the six months ended June 30, 2017, also included the impacts of the Internal Revenue Service ("IRS") announcement of its final regulations on qualifying income in January 2017, discussed below.

In January 2017, the IRS announced its decision to exclude cokemaking as a qualifying income generating activity in its final regulations (the "Final Regulations") issued under section 7704(d)(1)(E) of the Internal Revenue Code relating to the qualifying income exception for publicly traded partnerships. However, the Final Regulations include a transition period for activities that were reasonably interpreted to be qualifying income and carried on by publicly traded partnerships prior to the Final Regulations. The Partnership previously received a will-level opinion from its counsel, Vinson & Elkins LLP, that the Partnership's cokemaking operations generated qualifying income prior to the Final Regulations. Therefore, the Partnership believes it had a reasonable basis to conclude its cokemaking operations were considered qualifying income before the issuance of the new regulations and as such expects to maintain its treatment as a partnership through the transition period. Cokemaking entities in the Partnership will become taxable as corporations on January 1, 2028, after the transition period ends.

As a result of the Final Regulations discussed above, the Partnership recorded deferred income tax expense of $148.6 million to set up its initial deferred income tax liability during the first quarter of 2017, primarily related to differences in the book and tax basis of fixed assets, which are expected to exist at the end of the 10-year transition period when the cokemaking operations become taxable.  As the Company consolidates the Partnership, the entire deferred income tax expense was recognized during the first quarter of 2017. However, the Company had already recorded $84.4 million of the deferred income tax liability in its financial statements related to the Company's share of the deferred tax liability for the book and tax differences in its investment in the Partnership. Therefore, the net impact to the Company’s deferred tax expense was $64.2 million during the six months ended June 30, 2017. This incremental tax impact is solely attributable to the Partnership’s public unitholders. As such, an equal reduction to noncontrolling interest was recorded. As a result, the Final Regulations have no impact to net income attributable to the Company.

The Company recorded income tax expense of zero and $3.3 million for the three and six months ended June 30, 2016, resulting in effective tax rates of zero percent and 19.5 percent, respectively, as compared to the 35.0 percent federal statutory rate, primarily due to the impact of earnings attributable to noncontrolling ownership interests in partnerships.

On January 17, 2012, SunCoke Energy and Sunoco, Inc. entered into a tax sharing agreement that governs the parties’ respective rights, responsibilities and obligations with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and other matters regarding taxes. SunCoke Energy will continue to monitor the utilization of all tax attributes subject to the tax sharing agreement as applicable tax returns are filed or as tax examinations progress and will record additional adjustments when necessary, consistent with the terms of the tax sharing agreement.

Issuance of 2025 Partnership Senior Notes

In May 2017, the Partnership issued $630.0 million aggregate principal amount of senior notes with an interest rate of 7.5 percentdue in May 2025. The Partnership received proceeds of $620.6 million, net of an original issue discount of $9.4 million. The Partnership incurred debt issuance costs related to this transaction of $11.8 million, which were included in long-term debt and financing obligation on the Consolidated Balance Sheets as of June 30, 2017. The 2025 Partnership Senior Notes are the senior unsecured obligations of the Partnership, and are guaranteed on a senior unsecured basis by each of the Partnership’s existing and certain future subsidiaries (other than SunCoke Energy Partners Finance Corp.). Interest on the 2025 Partnership Senior Notes is payable semi-annually in cash in arrears on June 15 and December 15 of each year, commencing on December 15, 2017.

The Partnership may redeem some or all of the 2025 Partnership Senior Notes at any time on or after June 15, 2020 at specified redemption prices plus accrued and unpaid interest, if any, to the redemption date. Before June 15, 2020, and following certain equity offerings, the Partnership also may redeem up to 35% of the 2025 Partnership Senior Notes at a price equal to 107.50% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date. In addition, at any time prior to June 15, 2020, the Partnership may redeem some or all of the 2025 Partnership Senior Notes at a price equal to 100% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date, plus a “make-whole” premium.

The Partnership is obligated to offer to purchase all or a portion of the 2025 Partnership Senior Notes at a price of (a) 101% of their principal amount, together with accrued and unpaid interest, if any, to the date of purchase, upon the occurrence of certain change of control events and (b) 100% of their principal amount, together with accrued and unpaid interest, if any, to the date of purchase, upon the occurrence of certain asset dispositions. These restrictions and prohibitions are subject to certain qualifications and exceptions set forth in the Indenture, including without limitation, reinvestment rights with respect to the proceeds of asset dispositions.

The Indenture contains covenants that, among other things, limit the Partnership’s ability and the ability of certain of the Partnership’s subsidiaries to (i) incur indebtedness, (ii) pay dividends or make other distributions, (ii) prepay, redeem or repurchase certain subordinated debt, (iv) make loans and investments, (v) sell assets, (vi) incur liens, (vii) enter into transactions with affiliates, (viii) enter into agreements restricting the ability of subsidiaries to pay dividends and (ix) consolidate or merge.

Purchase and Redemption of 2020 Partnership Senior Notes and Repayment of the Partnership Term Loan

During the second quarter of 2017, the Partnership used the proceeds from the issuance of the 2025 Partnership Notes to purchase and redeem all of its 2020 Partnership Notes, including principal of $463.0 million and a premium of $18.7 million, and to repay the $50.0 millionoutstanding on the Partnership Term Loan. As a result, during the three and six months ended June 30, 2017, the Partnership recorded a loss on extinguishment of debt on the Consolidated Statement of Operations of $19.1 million, which included the premium paid and a write-off of unamortized debt issuance costs of $7.0 million partly offset by a write-off of unamortized premiums of $6.6 million.

Revolving Facility

In February 2017, the Company extended the maturity of its Revolving Facility to December 2018 and reduced its capacity by $25.0 million to $125.0 million, resulting in additional debt issuance costs of $0.6 million, which were included in long-term debt and financing obligation on the Consolidated Balance Sheets as of June 30, 2017. Additionally, the Company recorded a loss on extinguishment of debt on the Consolidated Statement of Operations of $0.1 million, representing a write-off of unamortized debt issuance costs, during the six months ended June 30, 2017.

In May 2017, the Company amended and restated its Revolving Facility, which extended its maturity date to May 2022 and reduced its capacity to $100.0 million, resulting in additional debt issuance costs of $1.1 million, which were included in long-term debt and financing obligation on the Consolidated Balance Sheets as of June 30, 2017. Additionally, the Company recorded a loss on extinguishment of debt on the Consolidated Statement of Operations of $0.3 million, representing a write-off of unamortized debt issuance costs, during the three and six months ended June 30, 2017. As of June 30, 2017, the Revolving Facility had letters of credit outstanding of $29.3 million and no outstanding balance, leaving $70.7 million available.

Partnership Revolver

In May 2017, the Partnership amended and restated the Partnership Revolver, which increased the Partnership's capacity from $250.0 million to $285.0 million and extended the maturity to May 2022, resulting in additional debt issuance costs of $3.0 million, which were included in long-term debt and financing obligation on the Consolidated Balance Sheets as of June 30, 2017. Additionally, the Partnership recorded a loss on extinguishment of debt on the Consolidated Statement of Operations of $0.8 million, representing a write-off of unamortized debt issuance costs, during the three and six months ended June 30, 2017.

The Partnership repaid the revolver outstanding balance of $172.0 million and borrowed $100.0 million under the amended and restated credit facility during the second quarter of 2017. As of June 30, 2017, the Partnership had $1.9 million of letters of credit outstanding and an outstanding balance of$100.0 million, leaving $183.1 million available.

Partnership's Promissory Note

During the three and six months ended June 30, 2017, the Partnership repaid $0.3 million and $0.6 million, respectively, of principal on the Partnership's Promissory Note. The Partnership intends to repay the outstanding balance on the Partnership's Promissory Note of $112.6 million in August 2017, primarily using available borrowing capacity under the Partnership Revolver.

Covenants

Under the terms of the Company's credit agreement, the Company is subject to a maximum leverage ratio of 3.25:1.00 and a minimum consolidated interest coverage ratio of 2.75:1.00. Under the terms of the Partnership's credit agreement, the Partnership is subject to a maximum consolidated leverage ratio of 4.5:1.0prior to June 30, 2020 and 4.0:1.0 after June 30, 2020 and a minimum consolidated interest coverage ratio of 2.5:1.0. The Company's and Partnership's credit agreements contain other covenants and events of default that are customary for similar agreements and may limit our ability to take various actions including our ability to pay a dividend or repurchase our stock.

Under the terms of the Promissory Note, Raven Energy LLC, a wholly-owned subsidiary of the Partnership, is subject to a maximum leverage ratio of 5.0:1.0 for any fiscal quarter ending prior to August 12, 2018. For any fiscal quarter ending on or after August 12, 2018 the maximum leverage ratio is 4.5:1.0. Additionally in order to make restricted payments, Raven Energy LLC is subject to a fixed charge ratio of 1.0:1.0.

If we fail to perform our obligations under these and other covenants, the lenders' credit commitment could be terminated and any outstanding borrowings, together with accrued interest, under the Revolving Facility, Partnership Revolver, and Promissory Note could be declared immediately due and payable. The Company and the Partnership have a cross default provision that applies to our indebtedness having a principal amount in excess of $35 million.

As of June 30, 2017, the Company and the Partnership were in compliance with all applicable debt covenants. We do not anticipate violation of these covenants nor do we anticipate that any of these covenants will restrict our operations or our ability to obtain additional financing.

Commitments and Contingent Liabilities

8. Commitments and Contingent Liabilities

Legal Matters

SunCoke Energy is party to an omnibus agreement pursuant to which we will provide indemnification to the Partnership upon the occurrence of certain potential adverse events under certain coke sales agreements, indemnification of certain environmental costs and preferential rights for growth opportunities.

The United States Environmental Protection Agency ("EPA") issued Notices of Violations (“NOVs”) for our Haverhill and Granite City cokemaking facilities which stemmed from alleged violations of our air emission operating permits for these facilities. We are working in a cooperative manner with the EPA, the Ohio Environmental Protection Agency and the Illinois Environmental Protection Agency to address the allegations, and have entered into a consent decree in federal district court with these parties. The consent decree includes a $2.2 million civil penalty payment, which was paid in December 2014, as well as capital projects underway to improve the reliability of the energy recovery systems and enhance environmental performance at the Haverhill and Granite City facilities. We anticipate spending between approximately $140 million and $145 million related to these projects, of which we have spent approximately $101 million to date. The remaining capital is expected to be spent through the first quarter of 2019. A portion of the proceeds from the Partnership's initial public offering and subsequent dropdowns are expected to be used to fund $119 million of these environmental remediation projects. Pursuant to the omnibus agreement, any amounts that the Partnership spends on these projects in excess of the $119 million will be reimbursed by the Company.

SunCoke Energy has also received NOVs, Findings of Violations ("FOVs"), and information requests from the EPA related to our Indiana Harbor cokemaking facility, which allege violations of certain air operating permit conditions for this facility. The Clean Air Act (the "CAA") provides the EPA with the authority to issue, among other actions, an order to enforce a State Implementation Plan ("SIP") 30 days after an NOV. The CAA also authorizes EPA enforcement of other non-SIP requirements immediately after an FOV. Generally, an NOV applies to SIPs and requires the EPA to wait 30 days, while an FOV applies to all other provisions (such as federal regulations) of the CAA, and has no waiting period. The NOVs and/or FOVs were received in 2010, 2012, 2013, 2015 and 2016. After discussions with the EPA and the Indiana Department of Environmental Management (“IDEM”) in 2010, resolution of the NOVs/FOVs was postponed by mutual agreement because of ongoing discussions regarding the NOVs at Haverhill and Granite City. In January 2012, the Company began working in a cooperative manner to address the allegations with the EPA, the IDEM and Cokenergy, Inc., an independent power producer that owns and operates an energy facility, including heat recovery equipment and a flue gas desulfurization system, that processes hot flue gas from our Indiana Harbor facility to produce steam and electricity and to reduce the sulfur and particulate content of such flue gas. The EPA, IDEM, SunCoke Energy and Cokenergy, Inc. have met regularly since those discussions commenced, and will continue to meet regularly in 2017 to attempt to agree upon a settlement of the NOVs and FOVs. Capital projects are underway to address items that may be required in conjunction with a settlement of the NOVs/FOVs. Any such settlement likely will require payment of a penalty for alleged past violations as well as undertaking capital projects to achieve compliance, and possibly enhance reliability and environmental performance of our Indiana Harbor facility. The settlement of most NOVs and FOVs typically involves first agreeing on injunctive relief and then agreeing on any appropriate penalty in light of the violations and the scope and cost of any injunctive relief.

Over the past several years, EPA, IDEM, SunCoke Energy and Cokenergy, Inc. have focused on the nature and extent of any injunctive relief to settle the NOVs/FOVs. Despite the negotiations, the scope and cost of any such injunctive relief remains uncertain, including any part of such injunctive relief that would be performed by SunCoke Energy. Likewise, the amount of any civil penalties that SunCoke Energy would be willing to pay in settlement of these claims is uncertain, and is contingent on the cost of any injunctive relief. As a result, SunCoke Energy cannot yet assess the scope or cost of any injunctive relief or potential monetary penalty. Moreover, the Company believes that it has meritorious defenses to many of the claims and that a failure to reach a settlement with the EPA regarding the NOVs and FOVs may lead to litigation in which rulings in the Company's favor on some or all of the allegations are possible. For these reasons, the Company is unable to reliably estimate a range of probable or reasonably possible loss.

The Company is a party to certain other pending and threatened claims, including matters related to commercial and tax disputes, product liability, employment claims, personal injury claims, premises-liability claims, allegations of exposures to toxic substances and general environmental claims. Although the ultimate outcome of these claims cannot be ascertained at this time, it is reasonably possible that some portion of these claims could be resolved unfavorably to the Company. Management of the Company believes that any liability which may arise from claims would not have a material adverse impact on our consolidated financial statements.

Black Lung Benefit Liabilities

The Company has obligations related to coal workers’ pneumoconiosis, or black lung, benefits to certain of our former coal mining employees (and their dependents). Such benefits are provided for under Title IV of the Federal Coal Mine and Safety Act of 1969 and subsequent amendments, as well as for black lung benefits provided in the states of Virginia, Kentucky and West Virginia pursuant to workers’ compensation legislation. The Patient Protection and Affordable Care Act (“PPACA”), which was implemented in 2010, amended previous legislation related to coal workers’ black lung obligations. PPACA provides for the automatic extension of awarded lifetime benefits to surviving spouses and changes the legal criteria used to assess and award claims. We act as a self-insurer for both state and federal black lung benefits and adjust our liability each year based upon actuarial calculations of our expected future payments for these benefits.

Our independent actuarial consultants calculate the present value of the estimated black lung liability annually based on actuarial models utilizing our population of former coal mining employees, historical payout patterns of both the Company and the industry, actuarial mortality rates, disability incidence, medical costs, death benefits, dependents, discount rates and the current federally mandated payout rates. The estimated liability may be impacted by future changes in the statutory mechanisms, modifications by court decisions and changes in filing patterns driven by perceptions of success by claimants and their advisors, the impact of which cannot be estimated. The estimated liability was $50.8 million and $50.2 million as of June 30, 2017 and December 31, 2016, respectively, of which $4.8 million was included in accrued liabilities on the Consolidated Balance Sheets in both periods.

Equity Classified Awards

During the six months ended June 30, 2017, the Company granted share-based compensation to eligible participants under the SunCoke Energy, Inc. Long-Term Performance Enhancement Plan (“SunCoke LTPEP”). All awards vest immediately upon a change in control and a qualifying termination of employment as defined by the SunCoke LTPEP.

Stock Options

The Company granted the following stock options during the six months ended June 30, 2017 with an exercise price equal to the closing price of our common stock on the date of grant.

		Weighted Average Per Share
	No. of Shares	Exercise Price		Grant Date Fair Value
Traditional stock options	84,332	$	9.85	$	5.17
Performance based options	80,595	$	9.85	$	4.55

The stock options vest in three equal annual installments beginning one year from the date of grant. In order to become exercisable, the performance based options also require the closing price of the Company's common stock to reach or exceed $14.78, or 150 percent of $9.85, for any 15 trading days during the three year period beginning on the grant date. The stock options expire ten years from the date of grant.

The Company calculates the value of each employee stock option, estimated on the date of grant, using the Black-Scholes option pricing model with a Monte Carlo simulation for the performance based options. The weighted-average fair value of employee stock options granted during the six months ended June 30, 2017 was based on using the following weighted-average assumptions:

	Six Months Ended June 30, 2017
Risk-free interest rate	2	%
Expected term	6 years
Volatility	54	%
Dividend yield	—	%

The risk-free interest rate assumption is based on the U.S. Treasury yield curve at the date of grant for periods which approximate the expected life of the option. The expected term of the employee options represent the average contractual term adjusted by the average vesting period of each option tranche. We used a blended expected volatility assumption that incorporates 90 percent historical volatility and 10 percent implied volatility. The historical volatility is calculated based on our historical daily stock returns over the options' expected term. The implied volatility is calculated based on our near-the-money call options traded over the 90-day period preceding the valuation date. The dividend yield assumption is based on the Company’s expectation of dividend payouts at the time of grant.

Restricted Stock Units Settled in Shares

The Company issued 22,628 stock-settled restricted stock units (“RSUs”) to certain employees for shares of the Company’s common stock during the six months ended June 30, 2017. The weighted average grant date fair value was $9.85 per share. The RSUs vest in three annual installments beginning one year from the date of grant. All awards vest immediately upon a change in control as defined by the SunCoke LTPEP.

Performance Share Units

The Company granted the following performance share units ("PSUs") for shares of the Company's common stock during the six months ended June 30, 2017 that vest on December 31, 2019:

	Shares	Fair Value per Share
PSUs(1)(2)	237,610	$	11.40

(1) The PSU awards are split 50/50 between the Company's three year cumulative Adjusted EBITDA performance measure and the Company's three year average pre-tax return on capital performance measure for its coke and logistics businesses and unallocated corporate expenses.

(2) The number of PSU's ultimately awarded will be determined by the above performance versus targets and the Company's three year total shareholder return ("TSR") as compared to the TSR of the companies making up the Nasdaq Iron & Steel Index ("TSR Modifier"). The TSR Modifier can impact the payout between 50 percent and 150 percent of the Company's final performance measure results.

The award may vest between zero and 250 percent of the original units granted. The fair value of the PSUs granted during the six months ended June 30, 2017 is based on the closing price of our common stock on the date of grant as well as a Monte Carlo simulation for the valuation of the TSR Modifier.

Liability Classified Awards

Restricted Stock Units Settled in Cash

During the six months ended June 30, 2017, the Company issued 95,364 restricted stock units to be settled in cash ("Cash RSUs"), which vest in three annual installments beginning one year from the grant date. The weighted average grant date fair value of the Cash RSUs granted during the six months ended June 30, 2017 was $9.85 and was based on the closing price of our common stock on the day of grant.

The Cash RSU liability at June 30, 2017 was adjusted based on the closing price of our common stock on June 30, 2017 of $10.90 per share. The liability at June 30, 2017 was $0.6 million, of which $0.4 million was included in accrued liabilities and $0.2 million was included in other deferred credits and liabilities on the Consolidated Balance Sheets.

Cash Incentive Award

The Company also granted share-based compensation to eligible participants under the SunCoke Energy, Inc. Long-Term Cash Incentive Plan ("SunCoke LTCIP"), which became effective January 1, 2016. The SunCoke LTCIP is designed to provide for performance-based, cash-settled awards.

The Company issued a grant date fair value award of $0.7 million during the six months ended June 30, 2017 that vest on December 31, 2019. The awards are split 50/50 between the Company's three cumulative Adjusted EBITDA performance and the Company's three year average per-tax return on capital for its coke and logistics businesses and unallocated corporate expense. The ultimate award value will be determined by the performance versus targets and the Company's three year TSR Modifier performance, but will be capped at 250 percent of the target award.

The cash incentive award liability at June 30, 2017 was adjusted based on the Company's three year cumulative Adjusted EBITDA performance and adjusted average pre-tax return on capital for the Company's coke and logistics businesses and unallocated corporate expenses.

Partnership Public Unit Purchase Program

On April 17, 2017, the Company's Board of Directors authorized a program for the Company to purchase outstanding Partnership public units at any time and from time to time in the open market, through privately negotiated transactions, block transactions, or otherwise for a total aggregate cost to the Company not to exceed $50.0 million. During the second quarter of 2017, the Company purchased 1,460,404, or approximately 7 percent, of outstanding Partnership public units in the open market for a total cost of $24.6 million, which resulted in a decrease of $15.4 million in noncontrolling interest on the Consolidated Balance Sheets related to the Partnership's net book value acquired by the Company. The Company decreased its additional paid-in capital balance by $5.8 million on the Consolidated Balance Sheets for the consideration paid in excess of the net book value of the noncontrolling interest acquired, net of a deferred tax adjustment of $3.4 million.

The following table summarizes the effects of the changes in the Company's ownership interest in the Partnership on SunCoke's equity:

Change from net income attributable to SunCoke Energy, Inc. and transfers to noncontrolling interest	$	(30.0	)	$	(29.0	)

In July 2017, the Company's Board of Directors authorized the Company to purchase an additional $50.0 million of Partnership public units in the open market. Subsequent to June 30, 2017, the Company purchased an additional 131,274 of outstanding Partnership public units in the open market for a total cost of $2.3 million, leaving a remaining public unit purchase program balance of $73.1 million as of July 26, 2017.

Earnings per Share

11. Earnings per Share

Basic earnings per share (“EPS”) has been computed by dividing net (loss) income available to SunCoke Energy, Inc. by the weighted average number of shares outstanding during the period. Except where the result would be anti-dilutive, diluted earnings per share has been computed to give effect to share-based compensation awards using the treasury stock method.

The following table sets forth the reconciliation of the weighted-average number of common shares used to compute basic EPS to those used to compute diluted EPS:

Fair Value Measurement

Fair Value Disclosures [Abstract]

Fair Value Measurement

13. Fair Value Measurement

The Company measures certain financial and non-financial assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. Fair value disclosures are reflected in a three-level hierarchy, maximizing the use of observable inputs and minimizing the use of unobservable inputs.

The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels are defined as follows:

• Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market.

• Level 2 - inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or model-derived valuations in which all significant inputs are observable for substantially the full term of the asset or liability.

• Level 3 - inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability.

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

Certain assets and liabilities are measured at fair value on a recurring basis. The Company's cash equivalents, which amounted to $4.5 million and $4.4 million at June 30, 2017 and December 31, 2016, respectively, were measured at fair value based on quoted prices in active markets for identical assets. These inputs are classified as Level 1 within the valuation hierarchy.

CMT Contingent Consideration

In connection with the CMT acquisition, the Partnership entered into a contingent consideration arrangement that requires the Partnership to make future payments to The Cline Group based on future volume over a specified threshold, price and contract renewals. The fair value of the contingent consideration was estimated based on a probability-weighted analysis using significant inputs that are not observable in the market, or Level 3 inputs. Key assumptions included probability adjusted levels of coal handling services provided by CMT, anticipated price per ton on future sales and probability of contract renewal, including length of future contracts, volume commitment, and anticipated price per ton. The fair value of the contingent consideration at June 30, 2017 and December 31, 2016 was $4.5 million and $4.2 million, respectively, and was included in other deferred credits and liabilities on the Consolidated Balance Sheets. As a result of the increase in fair value, the Partnership recognized $0.3 million of additional expense in costs of products sold and operating expenses on the Consolidated Statements of Operations during the three and six months ended June 30, 2017. During the first quarter of 2016, the Partnership amended the contingent consideration terms with The Cline Group, which resulted in a $3.7 million gain recognized as a reduction to costs of products sold and operating expenses on the Consolidated Statements of Operations during the six months ended June 30, 2016.

Certain Financial Assets and Liabilities not Measured at Fair Value

At June 30, 2017 and December 31, 2016, the fair value of the Company’s total debt was estimated to be $895.4 million and $854.4 million, respectively, compared to a carrying amount of $901.2 million and $858.0 million, respectively. The fair value was estimated by management based upon estimates of debt pricing provided by financial institutions, which are considered Level 2 inputs.

Segment Reporting [Abstract]

Business Segment Information

14. Business Segment Information

The Company reports its business through three segments: Domestic Coke, Brazil Coke and Coal Logistics. The Domestic Coke segment includes the Jewell, Indiana Harbor, Haverhill, Granite City and Middletown cokemaking facilities. Each of these facilities produces coke, and all facilities except Jewell and Indiana Harbor recover waste heat, which is converted to steam or electricity through a similar production process. Steam is provided to customers pursuant to steam supply and purchase agreements. Electricity is sold into the regional power market or to AK Steel Holding Corporation ("AK Steel") pursuant to energy sales agreements. Coke sales at each of the Company's five domestic cokemaking facilities are made pursuant to long-term, take-or-pay agreements with ArcelorMittal S.A., AK Steel, and United States Steel Corporation. Each of the coke sales agreements contains pass-through provisions for costs incurred in the cokemaking process, including coal procurement costs (subject to meeting contractual coal-to-coke yields), operating and maintenance expense, costs related to the transportation of coke to the customers, taxes (other than income taxes) and costs associated with changes in regulation, in addition to containing a fixed fee.

The Brazil Coke segment operates a cokemaking facility located in Vitória, Brazil for a project company. The Brazil Coke segment earns income from the Brazilian facility through licensing and operating fees payable to us under long-term contracts with the local project company that will run through at least 2023.

Coal Logistics operations are comprised of CMT, located in Louisiana, KRT, located in West Virginia, SunCoke Lake Terminal, located in Indiana, and DRT, located in Virginia adjacent to our Jewell cokemaking facility. Our coal logistics operations have a collective capacity to mix and transload approximately 40 million tons of coal annually and provide coal handling and/or mixing services to its customers, which include the Partnership's cokemaking facilities and other SunCoke cokemaking facilities. Coal handling and mixing results are presented in the Coal Logistics segment.

Corporate expenses that can be identified with a segment have been included in determining segment results. The remainder is included in Corporate and Other, which also includes activity from our legacy coal mining business, which was historically presented as a separate reportable segment. Prior year periods have been recasted to reflect current presentation.

Segment assets, net of tax are those assets utilized within a specific segment and exclude deferred taxes and current tax receivables.

The following table includes Adjusted EBITDA, which is the measure of segment profit or loss and liquidity reported to the chief operating decision maker for purposes of allocating resources to the segments and assessing their performance:

The Company evaluates the performance of its segments based on segment Adjusted EBITDA, which is defined asearnings before interest, loss (gain) on extinguishment of debt, taxes, depreciation and amortization (“EBITDA”), adjusted for impairments, coal rationalization costs, changes to our contingent consideration liability related to our acquisition of CMT and the expiration of certain acquired contractual obligations. EBITDA and Adjusted EBITDA do not represent and should not be considered alternatives to net income or operating income under 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. Set forth below is additional discussion of the limitations of Adjusted EBITDA as an analytical tool.

Limitations. Other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure. Adjusted EBITDA also has limitations as an analytical tool and should not be considered in isolation or as a substitute for an analysis of our results as reported under GAAP. Some of these limitations include that Adjusted EBITDA:

• does not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments;

• does not reflect items such as depreciation and amortization;

• does not reflect changes in, or cash requirement for, working capital needs;

• does not reflect our interest expense, or the cash requirements necessary to service interest on or principal payments of our debt;

• does not reflect certain other non-cash income and expenses;

• excludes income taxes that may represent a reduction in available cash; and

• includes net income attributable to noncontrolling interests.

Below is a reconciliation of Adjusted EBITDA to net income and net cash provided by operating activities, which are its most directly comparable financial measures calculated and presented in accordance with GAAP:

Adjusted EBITDA attributable to SunCoke Energy, Inc.	$	30.0		$	27.9		$	64.0		$	51.4

(1) Prior to the divestiture of our coal mining business, the Company incurred coal rationalization costs including employee severance, contract termination costs and other costs to idle mines incurred during the execution of our coal rationalization plan.

(2) As a result of the increase in fair value of the contingent consideration liability during the second quarter of 2017, the Partnership recognized expense of $0.3 million during the three and six months ended June 30, 2017. The Partnership amended its contingent consideration terms with The Cline Group during the first quarter of 2016. This amendment resulted in a gain of $3.7 million recorded during the six months ended June 30, 2016.

(3) In 2014, we finalized the required permitting and engineering plan for a potential new cokemaking facility to be constructed in Kentucky. However, in June 2017, due to our focus on renewing our existing customer contracts and the lack of any long-term customer commitment for a majority of the facility's capacity, we decided to terminate the project. As a result, during the second quarter of 2017, the Company wrote-off previously capitalized engineering and land deposit costs of $5.3 million. During the second quarter of 2016, the Company wrote-off expiring land deposits related to the project of $1.9 million.

(4) In accordance with the SEC’s May 2016 update of its guidance on the appropriate use of non-GAAP financial measures, Adjusted EBITDA does not include Coal Logistics deferred revenue until it is recognized as GAAP revenue.

(5) Reflects noncontrolling interest in Indiana Harbor and the portion of the Partnership owned by public unitholders.

Supplemental Condensed Consolidating Financial Information

15. Supplemental Condensed Consolidating Financial Information

Certain 100 percent owned subsidiaries of the Company serve as guarantors of the obligations under the Credit Agreement and $44.6 million of Notes (“Guarantor Subsidiaries”). These guarantees are full and unconditional (subject, in the case of the Guarantor Subsidiaries, to customary release provisions as described below) and joint and several. For purposes of the following footnote, SunCoke Energy, Inc. is referred to as “Issuer.” The indenture dated July 26, 2011 among the Company, the guarantors party thereto and The Bank of New York Mellon Trust Company, N.A., governs subsidiaries designated as “Guarantor Subsidiaries.” All other consolidated subsidiaries of the Company are collectively referred to as “Non-Guarantor Subsidiaries.”

The ability of the Partnership and Indiana Harbor to pay dividends and make loans to the Company is restricted under the partnership agreements of the Partnership and Indiana Harbor, respectively. The credit agreement governing the Partnership’s credit facility and the indenture governing the Partnership Notes contain customary provisions which would potentially restrict the Partnership’s ability to make distributions or loans to the Company under certain circumstances. For the year ended December 31, 2016, less than 25 percent of net assets were restricted. Additionally certain coal mining entities are designated as unrestricted subsidiaries. As such, all the subsidiaries described above are presented as "Non-Guarantor Subsidiaries." There have been no changes to the "Guarantor Subsidiaries" and "Non-Guarantor Subsidiaries" during 2017.

The guarantee of a Guarantor Subsidiary will terminate upon:

• a sale or other disposition of the Guarantor Subsidiary or of all or substantially all of its assets;

• a sale of the majority of the Capital Stock of a Guarantor Subsidiary to a third-party, after which the Guarantor Subsidiary is no longer a "Restricted Subsidiary" in accordance with the indenture governing the Notes;

• the liquidation or dissolution of a Guarantor Subsidiary so long as no "Default" or "Event of Default", as defined under the indenture governing the Notes, has occurred as a result thereof;

• the designation of a Guarantor Subsidiary as an "unrestricted subsidiary" in accordance with the indenture governing the Notes;

• the requirements for defeasance or discharge of the indentures governing the Notes having been satisfied; and

• the release, other than the discharge through payments by a Guarantor Subsidiary, from its guarantee under the Credit Agreement or other indebtedness that resulted in the obligation of the Guarantor Subsidiary under the indenture governing the Notes.

The following supplemental condensed combining and consolidating financial information reflects the Issuer’s separate accounts, the combined accounts of the Guarantor Subsidiaries, the combined accounts of the Non-Guarantor Subsidiaries, the combining and consolidating adjustments and eliminations and the Issuer’s consolidated accounts for the dates and periods indicated. For purposes of the following condensed combining and consolidating information, the Issuer’s investments in its subsidiaries and the Guarantor and Non-Guarantor Subsidiaries’ investments in its subsidiaries are accounted for under the equity method of accounting.

New Accounting Pronouncements

New Accounting Pronouncements

In May 2014, Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Subsequently, the FASB has issued various ASUs to provide further clarification around certain aspects of ASC 606. This standard will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and early adoption is permitted on a limited basis. Our implementation team has gained an understanding of the standard’s revenue recognition model and is completing the analysis and documentation of our contract details for impacts under the new revenue recognition model. Based on the current status of our assessment, we expect the timing of our revenue recognition to generally remain the same under the new standard on an annual basis. Deferred revenue at Convent Marine Terminal may be recognized on a more accelerated basis during quarterly periods within the year based on facts and circumstances considered at each quarter under the new guidance. The Company expects to adopt this standard on January 1, 2018 using the modified retrospective method.

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires lessees to be recognized as assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. It is effective for annual and interim periods in fiscal years beginning after December 15, 2018, with early adoption permitted. The standard requires the use of a modified retrospective transition method. A multi-disciplined implementation team has gained an understanding of the accounting and disclosure provisions of the standard and is in the process of analyzing the impacts to our business, including the development of new accounting processes to account for our leases and support the required disclosures. While we are still evaluating the impact of adopting this standard, we expect that upon adoption the right-of-use assets and lease liabilities, such as various plant equipment rentals and the lease of our corporate office space, will increase the reported assets and liabilities on our Consolidated Balance Sheets. The Company expects to adopt this standard on January 1, 2019.

Adjusted EBITDA attributable to SunCoke Energy, Inc.	$	30.0		$	27.9		$	64.0		$	51.4

(1) Prior to the divestiture of our coal mining business, the Company incurred coal rationalization costs including employee severance, contract termination costs and other costs to idle mines incurred during the execution of our coal rationalization plan.

(2) As a result of the increase in fair value of the contingent consideration liability during the second quarter of 2017, the Partnership recognized expense of $0.3 million during the three and six months ended June 30, 2017. The Partnership amended its contingent consideration terms with The Cline Group during the first quarter of 2016. This amendment resulted in a gain of $3.7 million recorded during the six months ended June 30, 2016.

(3) In 2014, we finalized the required permitting and engineering plan for a potential new cokemaking facility to be constructed in Kentucky. However, in June 2017, due to our focus on renewing our existing customer contracts and the lack of any long-term customer commitment for a majority of the facility's capacity, we decided to terminate the project. As a result, during the second quarter of 2017, the Company wrote-off previously capitalized engineering and land deposit costs of $5.3 million. During the second quarter of 2016, the Company wrote-off expiring land deposits related to the project of $1.9 million.

(4) In accordance with the SEC’s May 2016 update of its guidance on the appropriate use of non-GAAP financial measures, Adjusted EBITDA does not include Coal Logistics deferred revenue until it is recognized as GAAP revenue.

(5) Reflects noncontrolling interest in Indiana Harbor and the portion of the Partnership owned by public unitholders.
