Notes to the Consolidated Financial Statements

1. General

Description of Business

SunCoke Energy, Inc. (“SunCoke Energy,” “SunCoke,” “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 60 years of coke production experience. Blast furnace coke is a principal raw material in the blast furnace steelmaking process and is produced by heating metallurgical coal in a refractory oven, which releases certain volatile components from the coal, thus transforming the coal into coke. Additionally, we own and operate a logistics business, which primarily provides handling and/or mixing services of coal and other aggregates to third-party customers as well as to our own cokemaking facilities.

We have designed, developed, built, own and operate five cokemaking facilities in the United States (“U.S.”), which consist of our Haverhill, Middletown, Granite City, Jewell and Indiana Harbor cokemaking facilities. Our cokemaking facilities have collective nameplate capacity to produce approximately 4.2 million tons of blast furnace coke per year. Our blast furnace coke sales are largely made pursuant to long-term, take-or-pay agreements with Cleveland-Cliffs Steel Holding Corporation and Cleveland-Cliffs Steel LLC, both subsidiaries of Cleveland Cliffs Inc. ("Cliffs") and collectively referred to as "Cliffs Steel," and United States Steel Corporation (“U.S. Steel”). Cliffs Steel and U.S. Steel are two of the largest blast furnace steelmakers in North America. Additionally, we have designed and operate one cokemaking facility in Brazil under licensing and operating agreements on behalf of ArcelorMittal Brasil S.A. (“ArcelorMittal Brazil”), which has approximately 1.7 million tons of annual cokemaking capacity.

In order to further diversify our business and customer base, we have entered the foundry coke market. Foundry coke is a high-quality grade of coke that is used at foundries to melt iron and various metals in cupola furnaces, which is further processed via casting or molding into products used in various industries such as construction, transportation and industrial products. We began producing and selling foundry coke on a commercial scale in 2021. We also began selling blast furnace coke into the export coke market in 2021, utilizing capacity in excess of that reserved for our long-term, take-or-pay agreements.

Our cokemaking ovens utilize efficient, modern heat recovery technology designed to combust the coal’s volatile components liberated during the cokemaking process and use the resulting heat to create steam or electricity for sale. This differs from by-product cokemaking, which repurposes the coal’s liberated volatile components for other uses. We have constructed the only greenfield cokemaking facilities in the U.S. in approximately 30 years and are the only North American coke producer that utilizes heat recovery technology in the cokemaking process. We provide steam pursuant to steam supply and purchase agreements with our customers. Electricity is sold into the regional power market or pursuant to energy sales agreements.

Our logistics business provides handling and/or mixing services to steel, coke (including some of our domestic cokemaking facilities), electric utility, coal producing and other manufacturing based customers. Our logistics business consists of Convent Marine Terminal (“CMT”), Kanawha River Terminal (“KRT”), SunCoke Lake Terminal (“Lake Terminal”) and Dismal River Terminal (“DRT”) and has collective capacity to mix and/or transload more than 40 million tons of coal and other aggregates annually and has total storage capacity of approximately 3 million tons.

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 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 period ended March 31, 2021 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, 2020.

2. Inventories

The components of inventories were as follows:

	March 31, 2021		December 31, 2020
	(Dollars in millions)
Coal	$	68.7	$	60.6
Coke	21.5		21.1
Materials, supplies and other	45.9		44.9
Total inventories	$	136.1	$	126.6

3. Intangible Assets

Intangible assets, net, include Goodwill allocated to our Domestic Coke segment of $3.4 million at both March 31, 2021 and December 31, 2020, and other intangibles detailed in the table below.

		March 31, 2021						December 31, 2020
	Weighted - Average Remaining Amortization Years	Gross Carrying Amount		Accumulated Amortization		Net		Gross Carrying Amount		Accumulated Amortization		Net
		(Dollars in millions)
Customer relationships	4	$	6.7	$	4.6	$	2.1	$	6.7	$	4.5	$	2.2
Permits	21	31.7		2.1		29.6		31.7		1.7		30.0
Other	29	1.6		—		1.6		1.6		—		1.6
Total		$	40.0	$	6.7	$	33.3	$	40.0	$	6.2	$	33.8

Total amortization expense for intangible assets subject to amortization was $0.5 million for the three months ended March 31, 2021 and $0.7 million for the three months ended March 31, 2020.

4. Income Taxes

At the end of each interim period, we make our best estimate of the effective tax rate and the impact of discrete items, if any, and adjust the rate as necessary.

The Company recorded income tax expense of $7.3 million for the three months ended March 31, 2021, resulting in an effective tax rate of 28.6 percent as compared to the 21.0 percent federal statutory rate. The difference between the Company’s effective tax rate and the statutory rate was primarily impacted by state taxes and disallowed expenses slightly offset by net income attributable to noncontrolling interest in our Indiana Harbor partnership for the three month period ended March 31, 2021.

The Company recorded income tax expense of $10.4 million for the three months ended March 31, 2020, resulting in an effective tax rate of 63.8 percent as compared to the 21.0 percent federal statutory rate. The difference between the Company's effective tax rate and the federal statutory rate during the three months ended March 31, 2020 was primarily driven by the revaluation of certain deferred tax assets due to lower apportioned state tax rates, which resulted in $6.5 million of deferred income tax expense. Additionally, the tax law passed in response to COVID-19, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act, enacted March 27, 2020, allowed the Company to carry back net operating losses generated in 2019 to each of the five years preceding 2019. As a result, SunCoke recorded an additional tax benefit of $1.0 million in the first quarter of 2020.

Accrued liabilities consisted of the following:

	March 31, 2021		December 31, 2020

	(Dollars in millions)
7.50 percent senior notes, due 2025 ("2025 Senior Notes")	$	587.3	$	587.3

Less: current portion of financing obligation	3.0		3.0
Total long-term debt and financing obligation	$	641.6	$	673.9

Revolving Facility

As of March 31, 2021, the Revolving Facility had letters of credit outstanding of $12.1 million and a $56.0 million outstanding balance, leaving $331.9 million available. Additionally, the Company has certain letters of credit totaling $11.5 million, which do not reduce the Revolving Facility's available balance.

Covenants

Under the terms of the Revolving Facility, the Company is subject to a maximum consolidated net leverage ratio of 4.50:1.00 and a minimum consolidated interest coverage ratio of 2.50:1.00. The Company's debt 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.

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 could be declared immediately due and payable. The Company has a cross default provision that applies to our indebtedness having a principal amount in excess of $35.0 million.

As of March 31, 2021, the Company was in compliance with all applicable debt covenants. We do not anticipate a violation of these covenants nor do we anticipate that any of these covenants will restrict our operations or our ability to obtain additional financing.

7. Commitments and Contingent Liabilities

Legal Matters

Between 2005 and 2012, the U.S. Environmental Protection Agency ("EPA") and the Ohio Environmental Protection Agency (“OEPA”) issued Notices of Violations (“NOVs”), alleging violations of air emission operating permits for our Haverhill and Granite City cokemaking facilities. We worked in a cooperative manner with the EPA, the OEPA and the Illinois Environmental Protection Agency to address the allegations and, in November 2014, entered into a consent decree with these parties in federal district court in the Southern District of Illinois. The consent decree included a civil penalty paid in December 2014, and a commitment to undertake capital projects to improve reliability and enhance environmental performance. The Haverhill project was completed in 2016, but completion of the Granite City project was delayed to June 2019, with SunCoke agreeing to pay an immaterial amount associated with the delay.

Between 2010 and 2016, SunCoke Energy also received certain NOVs, Findings of Violations (“FOVs”), and information requests from the EPA, alleging violations of air operating permit conditions related to our Indiana Harbor cokemaking facility. To reach a settlement of these NOVs and FOVs, we met regularly with the EPA, the Indiana Department of Environmental Management and Cokenergy, LLC., an independent power producer that processes hot flue gas from our Indiana Harbor facility to reduce the sulfur and particulate content and produce steam and electricity. A consent decree among the parties was entered by the federal district court in the Northern District of Indiana during the fourth quarter of 2018. The settlement included a civil penalty paid in the fourth quarter of 2018, and implementation of certain capital projects, completed during the fourth quarter of 2019, to improve reliability and environmental performance of the coke ovens at the facility.

The Company is a party to certain other pending and threatened claims, including matters related to commercial disputes, employment claims, personal injury claims, common law tort claims and 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 these claims would not have a material adverse impact on our consolidated financial statements. SunCoke's threshold for disclosing material environmental legal proceedings involving a government authority where potential monetary sanctions are involved is $1.0 million.

Black Lung Benefit Liabilities

The Company has obligations related to coal workers’ pneumoconiosis, or black lung, benefits to certain of its former coal miners 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. On February 1, 2013, SunCoke obtained commercial insurance for black lung claims in excess of a deductible for employees with a last date of employment after that date. Also during 2013, we were reauthorized to continue to self-insure black lung liabilities incurred prior to February 1, 2013 by the U.S. Department of Labor's Division of Coal Mine Workers' Compensation ("DCMWC") in exchange for $8.4 million of collateral.

We 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 miners, 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 $65.5 million and $64.6 million at March 31, 2021 and December 31, 2020, respectively, of which the current portion of $4.6 million was included in accrued liabilities on the Consolidated Balance Sheets in both periods.

In July 2019, the DCMWC required that SunCoke, along with a number of other companies, file an application and supporting documentation for reauthorization to self-insure our legacy black lung obligations incurred prior to February 1, 2013. The Company provided the requested information in the fourth quarter of 2019. The DCMWC subsequently notified the Company in a letter dated February 21, 2020 that the Company was reauthorized to self-insure certain of its black lung obligations; however, the reauthorization is contingent upon the Company providing collateral of $40.4 million to secure certain of its black lung obligations. This proposed collateral requirement is a substantial increase from the $8.4 million in collateral that the Company currently provides to secure these self-insured black lung obligations. The reauthorization process provided the Company with the right to appeal the security determination. SunCoke exercised its right to appeal the DCMWC’s security determination and provided additional information supporting the Company’s position in May 2020 and February 2021. If the

9

Company’s appeal is unsuccessful, the Company may be required to provide additional collateral to receive the self-insurance reauthorization from the DCMWC, which could potentially reduce the Company’s liquidity.

8. Share-Based Compensation

Equity Classified Awards

During the three months ended March 31, 2021, 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 qualifying termination of employment, as defined by the SunCoke LTPEP, following a change in control.

Restricted Stock Units Settled in Shares

The Company issued 421,518 stock-settled restricted stock units (“RSUs”) to certain employees to be settled in shares of the Company’s common stock during the three months ended March 31, 2021. The weighted average grant date fair value was $6.68 per unit and was based on the closing price of our common stock on the day of the grant. The RSUs vest in three annual installments beginning one year from the date of grant.

Performance Share Units

Performance share units (“PSUs”) were granted to certain employees to be settled in shares of the Company's common stock during the three months ended March 31, 2021, for which the service period will end on December 31, 2023 and will vest during the first quarter of 2024. The service period for certain retiree eligible participants is accelerated. The Company granted the following PSUs:

	Shares	Grant Date Fair Value per Unit
PSUs(1)(2)	177,176	$	7.60

(1)The PSU awards are split 50/50 between the Company's three year cumulative Adjusted EBITDA (as defined in Note 12) 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 PSUs ultimately awarded will be determined by the above performance measures 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 75 percent and 125 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 three months ended March 31, 2021 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.

Stock Options

The Company did not grant any stock options during the three months ended March 31, 2021.

Liability Classified Awards

Restricted Stock Units Settled in Cash

During the three months ended March 31, 2021, the Company issued 230,056 restricted stock units to certain employees to be settled in cash (“Cash RSUs”), which vest in three annual installments beginning one year from the grant date and are part of the SunCoke LTPEP. The weighted average grant date fair value of the Cash RSUs granted during the three months ended March 31, 2021 was $6.68 per unit and was based on the closing price of our common stock on the day of grant.

9. Earnings per Share

Basic earnings per share (“EPS”) has been computed by dividing net income attributable 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 March 31,
	2021	2020
	(Shares in millions)

10. 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 and cash equivalents were measured at fair value at March 31, 2021 and December 31, 2020 based on quoted prices in active markets for identical assets. These inputs are classified as Level 1 within the valuation hierarchy.

Certain Financial Assets and Liabilities not Measured at Fair Value

At March 31, 2021 and December 31, 2020, the fair value of the Company’s total debt was estimated to be $679.2 million and $683.9 million, respectively, compared to a carrying amount of $657.5 million and $690.5 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.

11. Revenue from Contracts with Customers

Cokemaking

Our blast furnace coke sales are largely made pursuant to long-term, take-or-pay coke sales agreements with Cliffs Steel and U.S. Steel, who are two of the largest blast furnace steelmakers in North America. The take-or-pay provisions in our agreements require our customers to purchase coke volumes as specified in the agreements or pay the contract price for any tonnage they do not purchase. The take-or-pay provisions of our agreements also require us to deliver minimum annual tonnage. Our coke sales agreements have approximately 16.6 million tons of unsatisfied or partially unsatisfied performance obligations, which are expected to be delivered over an average remaining contract term of approximately five years.

Foundry coke sales are generally made under annual agreements with our customers for an agreed upon price and do not contain take-or-pay volume commitments. Export coke sales are generally made on a spot basis at the current market price.

Revenues on all coke sales are recognized when performance obligations to our customers are satisfied in an amount that reflects the consideration that we expect to receive in exchange for the coke.

12

Logistics

In our logistics business, handling and/or mixing services are provided to steel, coke (including some of our domestic cokemaking facilities), electric utility, coal producing and other manufacturing based customers. Materials are transported in numerous ways, including rail, truck, barge or ship. We do not take possession of materials handled, but rather act as intermediaries between our customers and end users, deriving our revenues from services provided on a per ton basis. The handling and mixing services consist primarily of two performance obligations, unloading and loading of materials. Revenues are recognized when the customer receives the benefits of the services provided, in an amount that reflects the consideration that we will receive in exchange for those services.

Estimated take-or-pay revenue of approximately $41.3 million from all of our multi-year logistics contracts is expected to be recognized over the next three years for unsatisfied or partially unsatisfied performance obligations as of March 31, 2021.

12. Business Segment Information

The Company reports its business through three segments: Domestic Coke, Brazil Coke and 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 recover waste heat, which is converted to steam or electricity.

The Brazil Coke segment includes the licensing and operating fees payable to us under long-term contracts with ArcelorMittal Brazil, under which we operate a cokemaking facility located in Vitória, Brazil through at least 2023.

Logistics operations are comprised of CMT, KRT, Lake Terminal, which provides services to our Indiana Harbor cokemaking facility, and DRT, which provides services to our Jewell cokemaking facility. Handling and mixing results are presented in the 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. Corporate and Other also includes activity from our legacy coal mining business.

Segment assets are those assets utilized within a specific segment and exclude taxes.

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

	Three Months Ended March 31,

The following table sets forth the Company's segment assets:

	March 31, 2021		December 31, 2020
	(Dollars in millions)
Segment assets
Domestic Coke	$	1,360.9	$	1,358.9

Segment assets, excluding income tax receivable	1,603.4		1,607.9
Tax assets	1.7		5.5
Total assets	$	1,605.1	$	1,613.4

The Company evaluates the performance of its segments based on segment Adjusted EBITDA, which is defined as earnings before interest, taxes, depreciation and amortization (“EBITDA”), adjusted for any impairments and gain on extinguishment of debt. 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 in assessing operating performance. Adjusted EBITDA provides useful information to investors because it highlights trends in our business that may not otherwise be apparent when relying solely on GAAP measures and because it eliminates items that have less bearing on our operating performance. EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP, and they should not be considered a substitute for net income or any other measure of financial performance presented in accordance with GAAP. Additionally, other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

Below is a reconciliation of Adjusted EBITDA to net income, which is its most directly comparable financial measure calculated and presented in accordance with GAAP:

	Three Months Ended March 31,
	2021		2020
	(Dollars in millions)
Net income attributable to SunCoke Energy, Inc.	$	16.5	$	4.9

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 in our filings with the SEC, including this Quarterly Report on Form 10-Q, and under “Cautionary Statement Concerning Forward-Looking Statements.”

Currently, such risks and uncertainties also include: SunCoke’s ability to manage its business during and after the COVID-19 pandemic; the impact of the COVID-19 pandemic on SunCoke’s results of operations, revenues, earnings and cash flows; SunCoke’s ability to reduce costs and capital spending in response to the COVID-19 pandemic; SunCoke’s balance sheet and liquidity throughout and following the COVID-19 pandemic; SunCoke’s prospects for financial performance and achievement of strategic objectives following the COVID-19 pandemic; capital allocation strategy following the COVID-19 pandemic; and the general impact on our industry and on the U.S. and global economy resulting from COVID-19, including actions by domestic and foreign governments and others to contain the spread, or mitigate the severity, thereof.

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 generally accepted accounting principles (“GAAP”) and certain other financial data that is prepared using a non-GAAP measure. For a reconciliation of the non-GAAP measure to its most comparable GAAP component, see “Non-GAAP Financial Measures” at the end of this Item and Note 12 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,” “SunCoke,” “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 60 years of coke production experience. Blast furnace coke is a principal raw material in the blast furnace steelmaking process and is produced by heating metallurgical coal in a refractory oven, which releases certain volatile components from the coal, thus transforming the coal into coke. We also own and operate a logistics business that primarily provides handling and/or mixing services to steel, coke (including some of our domestic cokemaking facilities), electric utility, coal producing and other manufacturing based customers.     

Cokemaking

We have designed, developed, built, own and operate five cokemaking facilities in the United States (“U.S.”), which consist of our Haverhill, Middletown, Granite City, Jewell and Indiana Harbor cokemaking facilities. These five cokemaking facilities have collective nameplate capacity to produce approximately 4.2 million tons of blast furnace coke per year. Additionally, we have designed and operate one cokemaking facility in Brazil under licensing and operating agreements on behalf of ArcelorMittal Brasil S.A. (“ArcelorMittal Brazil”), which has approximately 1.7 million tons of annual cokemaking capacity.

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. Our blast furnace coke sales are largely made pursuant to long-term, take-or-pay agreements with Cleveland-Cliffs Steel Holding Corporation and Cleveland-Cliffs Steel LLC, both subsidiaries of Cleveland Cliffs Inc. ("Cliffs") and collectively referred to as "Cliffs Steel," and United States Steel Corporation ("U.S. Steel"). Cliffs Steel and U.S. Steel are two of the largest blast furnace steelmakers in North America. These coke sales agreements have an average remaining term of approximately five years based on annual nameplate capacity 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 coal component of the Jewell coke price is based on the weighted-average contract price of third-party coal purchases at our Haverhill facility applicable to Cliffs Steel coke sales.

In order to further diversify our business and customer base, we have entered the foundry coke market. Foundry coke is a high-quality grade of coke that is used at foundries to melt iron and various metals in cupola furnaces, which is further processed via casting or molding into products used in various industries such as construction, transportation and industrial products. We began producing and selling foundry coke on a commercial scale in 2021. We also began selling blast furnace coke into the export coke market in 2021, utilizing capacity in excess of that reserved for our long-term, take-or-pay agreements.

16

U.S. steel production utilization rates have continued to strengthen in the first quarter of 2021, benefiting our steelmaking customers. Utilization has increased from 75 percent in January 2021 to 78 percent in April 2021. We expect continued strength of U.S. steel production utilization rates throughout 2021.

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. 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.

The following table sets forth information about our cokemaking facilities and our coke and energy sales agreements as of March 31, 2021:

Facility	Location	Customer	Year of Start Up	Contract Expiration	Number of Coke Ovens	Annual Cokemaking Nameplate Capacity(1) (thousands of tons)	Use of Waste Heat
Owned and Operated:
Jewell	Vansant, Virginia	Cliffs Steel	1962	December 2025	142	720	Partially used for thermal coal  drying
Indiana Harbor	East Chicago, Indiana	Cliffs Steel	1998	October 2023	268	1,220	Heat for power generation
Haverhill I	Franklin Furnace, Ohio	Cliffs Steel	2005	December 2025	100	550	Process steam
Haverhill II	Franklin Furnace, Ohio	Cliffs Steel	2008	June 2025	100	550	Power generation
Granite City	Granite City, Illinois	U.S. Steel	2009	December 2024	120	650	Steam for power generation
Middletown(2)	Middletown, Ohio	Cliffs Steel	2011	December 2032	100	550	Power generation
					830	4,240
Operated:
Vitória	Vitória, Brazil	ArcelorMittal Brazil	2007	January 2023	320	1,700	Steam for power generation
					1,150	5,940

(1)Cokemaking nameplate capacity represents stated capacity for production of blast furnace coke. The minimum tons in our coke sales agreements may be lower than the annual cokemaking nameplate capacity.

(2)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.

Logistics

Our logistics business consists of Convent Marine Terminal (“CMT”), Kanawha River Terminal (“KRT”), Lake Terminal and Dismal River Terminal (“DRT”). CMT is located in Convent, Louisiana, with strategic access to seaborne markets for coal and other industrial materials. The terminal provides loading and unloading services and has direct rail access and has the current capability to transload 15 million tons annually with its top of the line shiploader. The facility serves coal mining customers as well as other merchant business, including aggregates (crushed stone), petroleum coke and iron ore. CMT's efficient barge unloading capabilities complement its rail and truck offerings and provide the terminal with the ability to transload and mix a significantly broader variety of materials, including coal, petroleum coke and other materials from barges at its dock. KRT is a leading metallurgical and thermal coal mixing and handling terminal service provider with collective capacity to mix and transload 25 million tons annually through its two operations in West Virginia. Lake Terminal and DRT provide coal handling and mixing services to SunCoke's Indiana Harbor and Jewell cokemaking operations, respectively.

Our logistics business has the collective capacity to mix and/or transload more than 40 million tons of coal and other aggregates annually and has storage capacity of approximately 3 million tons. Our terminals act as intermediaries between our customers and end users by providing transloading and mixing services. Materials are transported in numerous ways, including rail, truck, barge or ship. We do not take title of the materials handled but instead derive our revenues by providing handling and/or mixing services to our customers on a per ton basis. Revenues are recognized when services are provided as defined by

17

customer contracts. Logistics services provided to our domestic cokemaking facilities are provided under contracts with terms equivalent to those of arm's-length transactions.

Certain 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"), as well as Newcastle index coal prices, as referenced in the Argus/McCloskey's Coal Price Index ("API6 index price"), which reflect low-ash coal prices shipped from Australia, contribute to our customers' decisions to place tons into the export market and thus impact transloading volumes through CMT. Higher natural gas prices in Europe resulted in an increase in global demand for coal and an increase in API2 prices during the first quarter of 2021, resulting in a strong export coal market and higher export coal volumes through CMT as compared to the same prior year period. The API2 forward curve projections indicate continued strength in the coal export market.

Our KRT terminals serve two primary domestic markets, metallurgical coal trade and thermal coal trade. Metallurgical markets are primarily impacted by steel prices and blast furnace operating levels whereas thermal markets are impacted by natural gas prices and electricity demand. In 2021, our cokemaking facilities are operating at full capacity. We continue to expect throughput volumes of 10 million tons at our domestic logistics terminals, up from approximately 9 million tons in 2020, and volumes from third party customers in 2021 to be consistent with 2020.

First Quarter Key Financial Results

Our consolidated results of operations were as follows:

	Three Months Ended March 31,				Increase
	2021		2020
	(Dollars in millions)
Net income	$	18.2	$	5.9	$	12.3
Net cash provided by operating activities	$	64.8	$	26.8	$	38.0
Adjusted EBITDA	$	70.6	$	62.1	$	8.5

Results in the first quarter of 2021 reflect strong operating performance driven by an increase in volumes in our Logistics segment. SunCoke is well positioned to achieve the high end of our 2021 Adjusted EBITDA guidance range of $215 million to $230 million. See detailed analysis of the quarter's results throughout the MD&A.

Results of Operations

The following table sets forth amounts from the Consolidated Statements of Income for the three months ended March 31, 2021 and 2020, respectively:

	Three Months Ended March 31,				Increase (Decrease)

Less: Net income attributable to noncontrolling interests	1.7		1.0		0.7
Net income attributable to SunCoke Energy, Inc.	$	16.5	$	4.9	$	11.6

Sales and Other Operating Revenue and Costs of Products Sold and Operating Expenses. Sales and other operating revenue and costs of products sold and operating expenses decreased for the three months ended March 31, 2021 compared to the same prior year period, primarily due to the pass-through of lower coal prices and lower volumes in our Domestic Coke segment. This decrease in Domestic Coke revenues was partially offset by higher logistics volumes at CMT.

Selling, General and Administrative Expenses. Selling, general and administrative expenses for the three months ended March 31, 2021 were impacted by lower professional services, the absence of foundry related research and development costs incurred in 2020, and lower employee related expenses, which were partly offset by $1.7 million of period-over-period, mark-to-market adjustments in deferred compensation driven by changes in the Company's share price during the three months ended March 31, 2021 as compared to the same prior year period.

Depreciation and Amortization Expense. Depreciation and amortization expense for the three months ended March 31, 2021 decreased due to the absence of additional depreciation associated with planned upgrades to certain heat recovery steam generators, which was recorded during the same prior year period.

Interest Expense, Net. Average debt balances during the three months ended March 31, 2021 and 2020 were $684.3 million and $803.9 million, respectively. This decrease was a result of both lower borrowings on the Revolving Facility as well as repurchases of Senior Notes during 2020.

Income Tax Expense. The decrease in income tax expense during the three months ended March 31, 2021 is due to the absence of the revaluation of certain deferred tax assets due to lower apportioned state tax rates which resulted in deferred income tax expense of $6.5 million during the same prior year period. See Note 4 to our consolidated financial statements.

Noncontrolling Interest. Net income attributable to noncontrolling interest represents a 14.8 percent third-party interest in our Indiana Harbor cokemaking facility. Net income from Indiana Harbor has increased in the current year period due to improved operational efficiencies, which resulted in favorable coal-to-coke yields and higher volumes. Higher net income at Indiana Harbor results in an increase to net income attributable to noncontrolling interest.

Results of Reportable Business Segments

We report our business results through three segments:

•Domestic Coke consists of our Jewell facility, located in Vansant, Virginia, our Indiana Harbor facility, located in East Chicago, Indiana, our Haverhill facility, located in Franklin Furnace, Ohio, our Granite City facility located in Granite City, Illinois, and our Middletown facility located in Middletown, Ohio.

•Brazil Coke consists of operations in Vitória, Brazil, where we operate the ArcelorMittal Brazil cokemaking facility.

•Logistics consists of CMT, located in Convent, Louisiana, KRT, located in Ceredo and Belle, West Virginia, Lake Terminal, located in East Chicago, Indiana, and DRT, located in Vansant, Virginia. Lake Terminal and DRT are located adjacent to our Indiana Harbor and Jewell cokemaking facilities, respectively.

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.

Management believes Adjusted EBITDA is an important measure of operating performance, 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 12 to our consolidated financial statements.

Analysis of Segment Results

Domestic Coke

Historically, SunCoke's analysis of our Domestic Coke segment has aligned with the pass-through nature of our long-term, take-or-pay contracts, including analysis of the prices of coal passed through and the reimbursement of operating maintenance spending as compared to prior year periods. Beginning in 2021, our Domestic Coke business has expanded into the export coke market and the foundry coke market. These sales do not contain the same pass-through provisions as our long-term, take-or-pay contracts. Therefore, the analysis of our Domestic Coke results has evolved to allow for the inclusion of these sales. The impact of fluctuating coal prices, including the value of coal-to-coke yield gains and losses, and indexed operating and maintenance reimbursement rates are now presented as price variances along with the impact of export and foundry sales prices as compared to prior period sales prices.

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

	Three Months Ended March 31, 2021 vs. 2020
	Sales and other operating revenue		Adjusted EBITDA
	(Dollars in millions)
Prior year period	$	365.2	$	63.4
Volume(1)	(7.4)		(3.7)
Price(2)	(24.0)		(0.5)
Operating and maintenance costs	N/A		1.7
Energy and other	1.5		2.6
Current year period	$	335.3	$	63.5

(1)Lower volume was primarily the result of timing of shipments.

(2)The decline in revenues was primarily related to the pass through of lower coal prices on our long-term, take-or-pay agreements.

Logistics

During the three months ended March 31, 2021 revenue was $22.7 million, and Adjusted EBITDA was $10.9 million. During the three months ended March 31, 2020 revenue was $15.6 million, and Adjusted EBITDA was $3.3 million. Increases in Logistics results as compared to the prior year period reflect the improved coal export market, which drove higher sales volumes at CMT.

Brazil

During the three months ended March 31, 2021, revenues were $8.5 million and Adjusted EBITDA was $4.5 million, which were comparable to results in the prior year period.

Corporate and Other

Corporate and Other Adjusted EBITDA was a loss of $8.3 million and $8.7 million for the three months ended March 31, 2021 and 2020, respectively. The three months ended March 31, 2021 was impacted by lower professional services and employee related costs as well as the absence of $0.8 million foundry related research and development costs incurred in 2020. These benefits were partially offset by $1.7 million of period-over-period, mark-to-market adjustments in deferred compensation driven by changes in the Company's share price during the three months ended March 31, 2021 as compared to the same prior year period.

Liquidity and Capital Resources

Our primary liquidity needs are to fund working capital, fund investments, service our debt, maintain cash reserves and replace partially or fully depreciated assets and other capital expenditures. 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

21

current resources are sufficient to meet our working capital requirements for our current business for at least the next 12 months and thereafter for the foreseeable future. However, the Company continues to evaluate whether any borrowings or other actions are needed to safeguard the business amidst the fluid market conditions and the uncertainty around the magnitude and duration of the COVID-19 pandemic. As of March 31, 2021, we had $54.0 million of cash and cash equivalents and $331.9 million of borrowing availability under our credit facility.

We may, from time to time, seek to retire or purchase additional amounts of our outstanding equity and/or debt securities through cash purchases and/or exchanges for other securities, in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material. Refer to further liquidity discussion below as well as Part II Item 2 - Unregistered Sales of Equity Securities and Use of Proceeds.

During the first quarter of 2020, the U.S. Department of Labor's Division of Coal Mine Workers' Compensation (“DCMWC”) requested SunCoke provide additional collateral of approximately $32 million to secure certain of its black lung obligations. SunCoke exercised its right to appeal the DCMWC’s determination and provided additional information supporting the Company’s position in May 2020 and February 2021. If the Company’s appeal is unsuccessful, the Company may be required to provide additional collateral to receive its self-insurance reauthorization from the DCMWC, which could potentially reduce the Company’s liquidity. See further discussion in Note 7 to our consolidated financial statements.

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 three months ended March 31, 2021 and 2020:

	Three Months Ended March 31,
	2021		2020
	(Dollars in millions)
Net cash provided by operating activities	$	64.8	$	26.8
Net cash used in investing activities	(20.1)		(22.8)
Net cash (used in) provided by financing activities	(39.1)		134.7
Net increase in cash and cash equivalents	$	5.6	$	138.7

Cash Flows from Operating Activities

Net cash provided by operating activities increased by $38.0 million to $64.8 million for the three months ended March 31, 2021 as compared to the corresponding prior year period, primarily reflecting a favorable impact from primary working capital, which is comprised of accounts receivable, inventories and accounts payable, driven by timing of coal purchases.

Cash Flows from Investing Activities

Net cash used in investing activities decreased by $2.7 million to $20.1 million for the three months ended March 31, 2021 as compared to the corresponding prior year period. Both periods primarily reflect ongoing capital expenditures.

Cash Flows from Financing Activities

Net cash used in financing activities was $39.1 million for the three months ended March 31, 2021 as compared to net cash provided by financing activities of $134.7 million in the corresponding prior year period. During the current year period, the Company made net repayments of $32.3 million on its Revolving Facility, as compared to net borrowings of $156.7 million during the same prior year period, and dividend payments of $5.1 million.

The prior year period reflects increased borrowings made to enhance the Company's cash position and preserve financial flexibility during the uncertainty around COVID-19. The prior year period also reflects $8.9 million of cash payments to redeem $12.0 million face value of 2025 Senior Notes, dividend payments of $5.0 million, and share repurchases of $7 million under the repurchase program discussed in Item 2 of Part II.

Dividends

On February 4, 2021, SunCoke's Board of Directors declared a cash dividend of $0.06 per share of the Company's common stock. This dividend was paid on March 1, 2021, to stockholders of record on February 19, 2021.

Additionally, on April 28, 2021, SunCoke's Board of Directors declared a cash dividend of $0.06 per share of the Company's common stock. This dividend will be paid on June 1, 2021, to stockholders of record on May 19, 2021.

22

Covenants

As of March 31, 2021, we were in compliance with all applicable debt covenants. We do not anticipate a 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 March 2021, S&P Global Ratings reaffirmed our corporate credit rating of BB- (stable). In April 2021, Moody’s Investors Service reaffirmed our corporate credit rating of B1 and changed the rating outlook from negative to stable.

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 grow our business through new markets or enable the renewal of a coke sales agreement and/or logistics service agreement and on which we expect to earn a reasonable return.

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

	Three Months Ended March 31,
	2021		2020
	(Dollars in millions)
Ongoing capital	$	16.4	$	22.8
Expansion capital(1)	3.7		—
Total capital expenditures(2)	$	20.1	$	22.8

(1)Includes capital spending in connection with the foundry cokemaking growth project, including $0.1 million of interest capitalized for the three months ended March 31, 2021.

(2)Reflects actual cash payments during the periods presented for our capital requirements.

In 2021, we expect our capital expenditures to be approximately $80 million.

Critical Accounting Policies

There have been no significant changes to our accounting policies during the three months ended March 31, 2021. Please refer to our Annual Report on Form 10-K filed on February 25, 2021 for a summary of these policies.

Recent Accounting Standards

There have been no new accounting standards material to SunCoke Energy, Inc. that have been adopted during the three months ended March 31, 2021.

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. 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 12 in our consolidated financial statements for both the definition of Adjusted EBITDA and its reconciliation from GAAP to the non-GAAP measurement for the three months ended March 31, 2021 and 2020, respectively.

Below is a reconciliation of 2021 Adjusted EBITDA guidance from its closest GAAP measure:

	2021
	Low		High
	(Dollars in millions)
Net income	$	15	$	35

Guarantor Financial and Non-Financial Disclosures

The Company has an existing shelf registration statement, which was filed on November 8, 2019, upon the expiration of the prior shelf registration statement, for the offering of debt and/or securities on a delayed or continuous basis and is presenting these guarantor financial and non-financial disclosures in connection therewith. The following information has been prepared and presented pursuant to amended SEC Rule 3-10 of Regulation S-X and new SEC Rule 13-01 of Regulation S-X, which were adopted by the SEC on March 2, 2020.

For purposes of the following information, SunCoke Energy, Inc. is referred to as “Issuer.” All 100 percent owned subsidiaries of the Company, including Finance Corp. and its consolidated subsidiaries, are expected to serve as guarantors of obligations (“Guarantor Subsidiaries”) included in the shelf registration statement, other than the Indiana Harbor partnership and certain of the Company’s corporate financing, international and legacy coal mining subsidiaries ("Non-Guarantors"). These guarantees will be full and unconditional (subject, in the case of the Guarantor Subsidiaries, to customary release provisions as described below) and joint and several.

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 indenture governing the notes having been satisfied; or

•the release, other than the discharge through payments by a Guarantor Subsidiary, from other indebtedness that resulted in the obligation of the Guarantor Subsidiary under the indenture governing the notes.

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 its Chief Executive Officer and Interim 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.

28

The Company carried out an evaluation, under the supervision and with the participation of management, including its Chief Executive Officer and Interim Chief Financial Officer, of the effectiveness 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 Interim 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.

Changes in Internal Control over Financial Reporting

There have been no changes in the Company’s internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting since our Annual Report on Form 10-K for the year ended December 31, 2020. We have not experienced any material impact to our internal controls over financial reporting due to COVID-19. We are continually monitoring and assessing the effects of COVID-19 on our internal controls to minimize the impact to their design and operating effectiveness.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

The information presented in Note 7 to our consolidated financial statements within this Quarterly Report on Form 10-Q is incorporated herein by reference.

Certain 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 disputes, employment claims, personal injury claims, common law tort claims, 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 March 31, 2021.

Item 1A. Risk Factors

There have been no material changes with respect to risk factors disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

On October 28, 2019, the Company's Board of Directors authorized a program to repurchase outstanding shares of the Company’s common stock, $0.01 par value, from time to time in open market transactions at prevailing market prices, in privately negotiated transactions, or by other means in accordance with federal securities laws, for a total aggregate cost to the Company not to exceed $100.0 million. There have been no share repurchases since the first quarter of 2020. As of March 31, 2021, $96.3 million remains available under the authorized repurchase program.

Item 4. Mine Safety Disclosures

While the Company divested substantially all of its remaining coal mining assets in April 2016, the Company continues to own certain logistics assets that are also regulated by Mine Safety and Health Administration. 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 and Item 104 of Regulation S-K (17 CFR 229.014) is included in Exhibit 95.1 to this Quarterly Report on Form 10-Q.

Exhibit 95.1

SunCoke Energy, Inc.

Mine Safety Disclosures for the Quarter Ended March 31, 2021

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 employ practices and conduct training to help ensure that our employees work safely. Furthermore, we utilize processes for managing, monitoring and improving safety and environmental performance.

We have consistently operated within the top quartiles 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.

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 March 31, 2021and 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 March 31, 2021.

(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 March 31, 2021. 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 March 31, 2021.

(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 (#)

Jewell Coal Corp / 44-00649	0	0	0	0	0	0
Total	0	0	0	0	0	0

(12)    This number reflects legal proceedings initiated before the FMSHRC during the quarter ended March 31, 2021. The number of “initiated legal actions” reported here may not have remained pending as of March 31, 2021.

(13)    This number reflects legal proceedings before the FMSHRC that were resolved during the quarter ended March 31, 2021.

Description of Business

SunCoke Energy, Inc. (“SunCoke Energy,” “SunCoke,” “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 60 years of coke production experience. Blast furnace coke is a principal raw material in the blast furnace steelmaking process and is produced by heating metallurgical coal in a refractory oven, which releases certain volatile components from the coal, thus transforming the coal into coke. Additionally, we own and operate a logistics business, which primarily provides handling and/or mixing services of coal and other aggregates to third-party customers as well as to our own cokemaking facilities.

We have designed, developed, built, own and operate five cokemaking facilities in the United States (“U.S.”), which consist of our Haverhill, Middletown, Granite City, Jewell and Indiana Harbor cokemaking facilities. Our cokemaking facilities have collective nameplate capacity to produce approximately 4.2 million tons of blast furnace coke per year. Our blast furnace coke sales are largely made pursuant to long-term, take-or-pay agreements with Cleveland-Cliffs Steel Holding Corporation and Cleveland-Cliffs Steel LLC, both subsidiaries of Cleveland Cliffs Inc. ("Cliffs") and collectively referred to as "Cliffs Steel," and United States Steel Corporation (“U.S. Steel”). Cliffs Steel and U.S. Steel are two of the largest blast furnace steelmakers in North America. Additionally, we have designed and operate one cokemaking facility in Brazil under licensing and operating agreements on behalf of ArcelorMittal Brasil S.A. (“ArcelorMittal Brazil”), which has approximately 1.7 million tons of annual cokemaking capacity.

In order to further diversify our business and customer base, we have entered the foundry coke market. Foundry coke is a high-quality grade of coke that is used at foundries to melt iron and various metals in cupola furnaces, which is further processed via casting or molding into products used in various industries such as construction, transportation and industrial products. We began producing and selling foundry coke on a commercial scale in 2021. We also began selling blast furnace coke into the export coke market in 2021, utilizing capacity in excess of that reserved for our long-term, take-or-pay agreements.

Our cokemaking ovens utilize efficient, modern heat recovery technology designed to combust the coal’s volatile components liberated during the cokemaking process and use the resulting heat to create steam or electricity for sale. This differs from by-product cokemaking, which repurposes the coal’s liberated volatile components for other uses. We have constructed the only greenfield cokemaking facilities in the U.S. in approximately 30 years and are the only North American coke producer that utilizes heat recovery technology in the cokemaking process. We provide steam pursuant to steam supply and purchase agreements with our customers. Electricity is sold into the regional power market or pursuant to energy sales agreements.

Our logistics business provides handling and/or mixing services to steel, coke (including some of our domestic cokemaking facilities), electric utility, coal producing and other manufacturing based customers. Our logistics business consists of Convent Marine Terminal (“CMT”), Kanawha River Terminal (“KRT”), SunCoke Lake Terminal (“Lake Terminal”) and Dismal River Terminal (“DRT”) and has collective capacity to mix and/or transload more than 40 million tons of coal and other aggregates annually and has total storage capacity of approximately 3 million tons.

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 under the symbol “SXC.”

Income Tax Disclosure [Abstract]

Income Taxes

4. Income Taxes

At the end of each interim period, we make our best estimate of the effective tax rate and the impact of discrete items, if any, and adjust the rate as necessary.

The Company recorded income tax expense of $7.3 million for the three months ended March 31, 2021, resulting in an effective tax rate of 28.6 percent as compared to the 21.0 percent federal statutory rate. The difference between the Company’s effective tax rate and the statutory rate was primarily impacted by state taxes and disallowed expenses slightly offset by net income attributable to noncontrolling interest in our Indiana Harbor partnership for the three month period ended March 31, 2021.

The Company recorded income tax expense of $10.4 million for the three months ended March 31, 2020, resulting in an effective tax rate of 63.8 percent as compared to the 21.0 percent federal statutory rate. The difference between the Company's effective tax rate and the federal statutory rate during the three months ended March 31, 2020 was primarily driven by the revaluation of certain deferred tax assets due to lower apportioned state tax rates, which resulted in $6.5 million of deferred income tax expense. Additionally, the tax law passed in response to COVID-19, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act, enacted March 27, 2020, allowed the Company to carry back net operating losses generated in 2019 to each of the five years preceding 2019. As a result, SunCoke recorded an additional tax benefit of $1.0 million in the first quarter of 2020.

Revolving Facility

As of March 31, 2021, the Revolving Facility had letters of credit outstanding of $12.1 million and a $56.0 million outstanding balance, leaving $331.9 million available. Additionally, the Company has certain letters of credit totaling $11.5 million, which do not reduce the Revolving Facility's available balance.

Covenants

Under the terms of the Revolving Facility, the Company is subject to a maximum consolidated net leverage ratio of 4.50:1.00 and a minimum consolidated interest coverage ratio of 2.50:1.00. The Company's debt 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.

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 could be declared immediately due and payable. The Company has a cross default provision that applies to our indebtedness having a principal amount in excess of $35.0 million.

As of March 31, 2021, the Company was in compliance with all applicable debt covenants. We do not anticipate a 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

7. Commitments and Contingent Liabilities

Legal Matters

Between 2005 and 2012, the U.S. Environmental Protection Agency ("EPA") and the Ohio Environmental Protection Agency (“OEPA”) issued Notices of Violations (“NOVs”), alleging violations of air emission operating permits for our Haverhill and Granite City cokemaking facilities. We worked in a cooperative manner with the EPA, the OEPA and the Illinois Environmental Protection Agency to address the allegations and, in November 2014, entered into a consent decree with these parties in federal district court in the Southern District of Illinois. The consent decree included a civil penalty paid in December 2014, and a commitment to undertake capital projects to improve reliability and enhance environmental performance. The Haverhill project was completed in 2016, but completion of the Granite City project was delayed to June 2019, with SunCoke agreeing to pay an immaterial amount associated with the delay.

Between 2010 and 2016, SunCoke Energy also received certain NOVs, Findings of Violations (“FOVs”), and information requests from the EPA, alleging violations of air operating permit conditions related to our Indiana Harbor cokemaking facility. To reach a settlement of these NOVs and FOVs, we met regularly with the EPA, the Indiana Department of Environmental Management and Cokenergy, LLC., an independent power producer that processes hot flue gas from our Indiana Harbor facility to reduce the sulfur and particulate content and produce steam and electricity. A consent decree among the parties was entered by the federal district court in the Northern District of Indiana during the fourth quarter of 2018. The settlement included a civil penalty paid in the fourth quarter of 2018, and implementation of certain capital projects, completed during the fourth quarter of 2019, to improve reliability and environmental performance of the coke ovens at the facility.

The Company is a party to certain other pending and threatened claims, including matters related to commercial disputes, employment claims, personal injury claims, common law tort claims and 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 these claims would not have a material adverse impact on our consolidated financial statements. SunCoke's threshold for disclosing material environmental legal proceedings involving a government authority where potential monetary sanctions are involved is $1.0 million.

Black Lung Benefit Liabilities

The Company has obligations related to coal workers’ pneumoconiosis, or black lung, benefits to certain of its former coal miners 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. On February 1, 2013, SunCoke obtained commercial insurance for black lung claims in excess of a deductible for employees with a last date of employment after that date. Also during 2013, we were reauthorized to continue to self-insure black lung liabilities incurred prior to February 1, 2013 by the U.S. Department of Labor's Division of Coal Mine Workers' Compensation ("DCMWC") in exchange for $8.4 million of collateral.

We 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 miners, 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 $65.5 million and $64.6 million at March 31, 2021 and December 31, 2020, respectively, of which the current portion of $4.6 million was included in accrued liabilities on the Consolidated Balance Sheets in both periods.

In July 2019, the DCMWC required that SunCoke, along with a number of other companies, file an application and supporting documentation for reauthorization to self-insure our legacy black lung obligations incurred prior to February 1, 2013. The Company provided the requested information in the fourth quarter of 2019. The DCMWC subsequently notified the Company in a letter dated February 21, 2020 that the Company was reauthorized to self-insure certain of its black lung obligations; however, the reauthorization is contingent upon the Company providing collateral of $40.4 million to secure certain of its black lung obligations. This proposed collateral requirement is a substantial increase from the $8.4 million in collateral that the Company currently provides to secure these self-insured black lung obligations. The reauthorization process provided the Company with the right to appeal the security determination. SunCoke exercised its right to appeal the DCMWC’s security determination and provided additional information supporting the Company’s position in May 2020 and February 2021. If the

Company’s appeal is unsuccessful, the Company may be required to provide additional collateral to receive the self-insurance reauthorization from the DCMWC, which could potentially reduce the Company’s liquidity.

Performance share units (“PSUs”) were granted to certain employees to be settled in shares of the Company's common stock during the three months ended March 31, 2021, for which the service period will end on December 31, 2023 and will vest during the first quarter of 2024. The service period for certain retiree eligible participants is accelerated. The Company granted the following PSUs:

	Shares	Grant Date Fair Value per Unit
PSUs(1)(2)	177,176	$	7.60

(1)The PSU awards are split 50/50 between the Company's three year cumulative Adjusted EBITDA (as defined in Note 12) 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 PSUs ultimately awarded will be determined by the above performance measures 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 75 percent and 125 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 three months ended March 31, 2021 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.

Stock Options

The Company did not grant any stock options during the three months ended March 31, 2021.

Liability Classified Awards

Restricted Stock Units Settled in Cash

During the three months ended March 31, 2021, the Company issued 230,056 restricted stock units to certain employees to be settled in cash (“Cash RSUs”), which vest in three annual installments beginning one year from the grant date and are part of the SunCoke LTPEP. The weighted average grant date fair value of the Cash RSUs granted during the three months ended March 31, 2021 was $6.68 per unit and was based on the closing price of our common stock on the day of grant.

The Cash RSU liability is adjusted based on the closing price of our common stock at the end of each quarterly period and was $1.0 million at March 31, 2021 and $1.1 million at December 31, 2020.

Cash Incentive Awards

The Company also granted long-term 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 qualifying termination of employment, as defined by the SunCoke LTCIP, following a change in control.

The Company issued awards with an aggregate grant date fair value of $2.1 million during the three months ended March 31, 2021, for which the service period will end on December 31, 2023 and will vest during the first quarter of 2024. The

service period for certain retiree eligible participants is accelerated. The awards are split 50/50 between the Company's three-year cumulative Adjusted EBITDA performance and the Company's three-year average pre-tax return on capital for its coke and logistics businesses and unallocated corporate expenses. The 2021 awards are not subject to the Company's three-year TSR Modifier performance.

The cash incentive award liability at March 31, 2021 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 was $0.9 million at March 31, 2021 and $1.3 million at December 31, 2020.

Fair Value Disclosures [Abstract]

Fair Value Measurement

10. 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 and cash equivalents were measured at fair value at March 31, 2021 and December 31, 2020 based on quoted prices in active markets for identical assets. These inputs are classified as Level 1 within the valuation hierarchy.

Certain Financial Assets and Liabilities not Measured at Fair Value

At March 31, 2021 and December 31, 2020, the fair value of the Company’s total debt was estimated to be $679.2 million and $683.9 million, respectively, compared to a carrying amount of $657.5 million and $690.5 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.

Revenue from Contracts with Customers

11. Revenue from Contracts with Customers

Cokemaking

Our blast furnace coke sales are largely made pursuant to long-term, take-or-pay coke sales agreements with Cliffs Steel and U.S. Steel, who are two of the largest blast furnace steelmakers in North America. The take-or-pay provisions in our agreements require our customers to purchase coke volumes as specified in the agreements or pay the contract price for any tonnage they do not purchase. The take-or-pay provisions of our agreements also require us to deliver minimum annual tonnage. Our coke sales agreements have approximately 16.6 million tons of unsatisfied or partially unsatisfied performance obligations, which are expected to be delivered over an average remaining contract term of approximately five years.

Foundry coke sales are generally made under annual agreements with our customers for an agreed upon price and do not contain take-or-pay volume commitments. Export coke sales are generally made on a spot basis at the current market price.

Revenues on all coke sales are recognized when performance obligations to our customers are satisfied in an amount that reflects the consideration that we expect to receive in exchange for the coke.

Logistics

In our logistics business, handling and/or mixing services are provided to steel, coke (including some of our domestic cokemaking facilities), electric utility, coal producing and other manufacturing based customers. Materials are transported in numerous ways, including rail, truck, barge or ship. We do not take possession of materials handled, but rather act as intermediaries between our customers and end users, deriving our revenues from services provided on a per ton basis. The handling and mixing services consist primarily of two performance obligations, unloading and loading of materials. Revenues are recognized when the customer receives the benefits of the services provided, in an amount that reflects the consideration that we will receive in exchange for those services.

Estimated take-or-pay revenue of approximately $41.3 million from all of our multi-year logistics contracts is expected to be recognized over the next three years for unsatisfied or partially unsatisfied performance obligations as of March 31, 2021.

Segment Reporting [Abstract]

Business Segment Information

12. Business Segment Information

The Company reports its business through three segments: Domestic Coke, Brazil Coke and 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 recover waste heat, which is converted to steam or electricity.

The Brazil Coke segment includes the licensing and operating fees payable to us under long-term contracts with ArcelorMittal Brazil, under which we operate a cokemaking facility located in Vitória, Brazil through at least 2023.

Logistics operations are comprised of CMT, KRT, Lake Terminal, which provides services to our Indiana Harbor cokemaking facility, and DRT, which provides services to our Jewell cokemaking facility. Handling and mixing results are presented in the 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. Corporate and Other also includes activity from our legacy coal mining business.

Segment assets are those assets utilized within a specific segment and exclude taxes.

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

Additionally, Corporate and Other includes foundry related research and development costs of $0.8 million during the three months ended March 31, 2020.

The following table sets forth the Company's segment assets:

Segment assets, excluding income tax receivable	1,603.4		1,607.9
Tax assets	1.7		5.5
Total assets	$	1,605.1	$	1,613.4

The Company evaluates the performance of its segments based on segment Adjusted EBITDA, which is defined as earnings before interest, taxes, depreciation and amortization (“EBITDA”), adjusted for any impairments and gain on extinguishment of debt. 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 in assessing operating performance. Adjusted EBITDA provides useful information to investors because it highlights trends in our business that may not otherwise be apparent when relying solely on GAAP measures and because it eliminates items that have less bearing on our operating performance. EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP, and they should not be considered a substitute for net income or any other measure of financial performance presented in accordance with GAAP. Additionally, other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

Below is a reconciliation of Adjusted EBITDA to net income, which is its most directly comparable financial measure calculated and presented in accordance with GAAP:
