PRELIMINARY JOINT PROSPECTUS/CONSENT STATEMENT/PROXY STATEMENT—SUBJECT TO COMPLETION—DATED APRIL 10, 2019

EXPLANATORY NOTE

On February 4, 2019, SunCoke Energy, Inc. (“SunCoke”) and its wholly owned subsidiary SC Energy Acquisition LLC (“Merger Sub” and, together with SunCoke, the “SunCoke Parties”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with SunCoke Energy Partners, L.P. (“SXCP”) and its general partner SunCoke Energy Partners GP LLC (“SXCP General Partner” and, together with SXCP, the “SXCP Parties”). Pursuant to the Merger Agreement, Merger Sub will be merged with and into SXCP, with SXCP being the surviving entity (the “Merger”).

Pursuant to the Merger Agreement, each outstanding common unit representing limited partner interests in SXCP (the “SXCP Common Units”) that is held by a unitholder other than SunCoke and any entities that are partially or wholly owned and controlled, directly or indirectly, by SunCoke, including Merger Sub, Sun Coal & Coke LLC (“SC&C”) and SXCP (such units, the “SXCP Public Units”), will be converted into the right to receive (x) 1.40 shares of validly issued, fully paid and non-assessable SunCoke common stock, par value $0.01 per share (“SunCoke Common Stock”) and (y) a fraction of a share of SunCoke Common Stock equal to the product of (aa) the number of days beginning with the first day of the most recent full calendar quarter with respect to which an SXCP unitholder distribution record date has not occurred (or, if there is no such full calendar quarter, then beginning with the first day of the partial calendar quarter in which the Closing (as defined in the Merger Agreement) occurs), and ending on the day immediately prior to the Closing, multiplied by (bb) a daily distribution rate that is equal to the quotient of the most recent regular quarterly cash distribution paid by SXCP divided by 90, such product divided by $10.91, which was the closing price of the SunCoke Common Stock as of February 1, 2019, the last full trading day prior to the date of the execution of the Merger Agreement. All SXCP Common Units, other than the SXCP Public Units, will remain outstanding following the Merger.

Prior to the Merger, SunCoke will hold a special meeting of its stockholders (the “SunCoke Special Meeting”) to approve the issuance of SunCoke Common Stock pursuant to the terms of the Merger Agreement in connection with the Merger (the “Parent Stock Issuance”). The closing of the Merger is conditioned upon approval of the Parent Stock Issuance (the “Parent Stock Issuance Approval”).

The conflicts committee (“SXCP Conflicts Committee”) of the board of directors of SXCP General Partner (the “SXCP Board”), by a unanimous vote at a meeting duly called and held on February 4, 2019, (i) determined that the Merger Agreement and the transactions contemplated thereby are in the best interest of SXCP, including the holders of SXCP Public Units, (ii) approved the Merger Agreement and the transactions contemplated thereby, including the Merger (the foregoing constituting SXCP Special Approval under the First Amended and Restated Agreement of Limited Partnership of SXCP dated as of January 24, 2013, as amended (the “SXCP Partnership Agreement”)), and (iii) recommended that the SXCP Board approve the Merger Agreement and the consummation of the transactions contemplated thereby, including the Merger.

Based upon such approval, at a meeting duly called and held on February 4, 2019, the SXCP Board (a) determined that the Merger Agreement and the transactions contemplated thereby are in the best interest of SXCP, (b) approved the Merger Agreement and the transactions contemplated thereby, including the Merger, and (c) directed that the Merger Agreement be submitted to a vote of holders of SXCP Common Units (“SXCP Common Unitholders”) and authorized the SXCP Common Unitholders to act by written consent pursuant to Section 13.11 of the SXCP Partnership Agreement.

At a meeting duly called and held on February 4, 2019, the board of directors of SunCoke (the “SunCoke Board”) (i) determined that the Merger Agreement and the transactions contemplated thereby, including the Merger and the Parent Stock Issuance, are in the best interests of SunCoke and its stockholders, (ii) approved and declared advisable the Merger Agreement and the transactions contemplated thereby, including the Merger and the Parent Stock Issuance, and (iii) resolved to submit the Parent Stock Issuance to a vote of SunCoke’s stockholders and recommend approval of the Parent Stock Issuance at the SunCoke Special Meeting (such recommendation, the “SunCoke Board Recommendation”).

The SunCoke Board has set                 , 2019 as the record date (the “SunCoke Vote Record Date”) for determining holders of SunCoke Common Stock (“SunCoke Stockholders”) entitled to vote at the SunCoke Special Meeting. If you are a SunCoke Stockholder of record as of the close of business on the SunCoke Vote Record Date, you may vote at the SunCoke Special Meeting. See the section titled “The SunCoke Special Meeting of Stockholders” of this joint prospectus/consent statement/proxy statement. The approval of the Parent Stock Issuance requires the affirmative vote (in person or by proxy) of the holders of a majority of the aggregate voting power present at the SunCoke Special Meeting or any adjournment or postponement thereof, provided a quorum is present. The Chairman of the SunCoke Board or the President of SunCoke may adjourn the SunCoke Special Meeting from time to time, whether or not there is a quorum. No notice of the time and place of adjourned meetings need be given except as required by law. The SunCoke Special Meeting may be postponed or canceled by resolution of the SunCoke Board upon public notice given prior to the date of the SunCoke Special Meeting.

The approval and adoption of the Merger Agreement and the Merger by SXCP requires the affirmative vote or consent of holders of at least a majority of the outstanding SXCP Common Units. Pursuant to the terms of a Support Agreement, dated as of February 4, 2019, by and between SC&C and SXCP (such agreement, the “Support Agreement”), SC&C, a wholly owned subsidiary of SunCoke which as of February 4, 2019, beneficially owned 28,499,899 SXCP Common Units representing approximately 61.7% of the outstanding SXCP Common Units, has agreed to deliver a written consent (the “SC&C Written Consent”), covering all of the SXCP Common Units beneficially owned by it, approving the Merger, the Merger Agreement and any other matters necessary for consummation of the Merger and the other transactions contemplated in the Merger Agreement, within two business days after the effectiveness of the registration statement of which this joint prospectus/consent statement/proxy statement forms a part. The delivery of the SC&C Written Consent by SC&C will be sufficient to approve the Merger Agreement and the transactions contemplated thereby, including the Merger, on behalf of SXCP.

The SXCP Board has set                 , 2019 as the record date (the “SXCP Record Date”) for determining holders of SXCP Common Units entitled to execute and deliver written consents with respect to the Merger. If you are a record holder of outstanding SXCP Common Units as of the close of business on the SXCP Record Date, you may complete, date and sign the enclosed written consent and return it to SXCP. See the Section titled “Written Consents of Holders of SXCP Common Units” beginning on page 26 of this joint prospectus/consent statement/proxy statement.

This joint prospectus/consent statement/proxy statement provides you with detailed information about the proposed Merger, the proposed Parent Stock Issuance and related matters. SunCoke and SXCP both encourage you to read the entire document carefully. In particular, please read “Risk Factors” beginning on page 19 of this joint prospectus/consent statement/proxy statement for a discussion of risks relevant to the Merger and the combined company.

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED OF THE SHARES OF SUNCOKE COMMON STOCK TO BE ISSUED IN THE MERGER OR DETERMINED IF THIS JOINT PROSPECTUS/CONSENT STATEMENT/PROXY STATEMENT IS TRUTHFUL OR COMPLETE OR PASSED UPON ITS ADEQUACY OR ACCURACY. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

The date of this joint prospectus/consent statement/proxy statement is                 , 2019 and it was first mailed to SunCoke Stockholders and SXCP Common Unitholders on or about                 , 2019.

QUESTIONS AND ANSWERS

The following section provides brief answers to certain questions that you may have regarding the Merger Agreement, the proposed Merger and the Parent Stock Issuance. Please note that this section does not address all issues that may be important to you as a SunCoke Stockholder and/or a SXCP Common Unitholder. Accordingly, you should carefully read this entire joint prospectus/consent statement/proxy statement, including each of the annexes, and the documents that have been incorporated by reference into this joint prospectus/consent statement/proxy statement.

General Questions and Answers

Q. Why am I receiving these materials?

A. The SunCoke Parties and the SXCP Parties have agreed to merge Merger Sub, a wholly owned subsidiary of SunCoke, with and into SXCP, with SXCP being the surviving entity in the Merger as an indirect wholly owned subsidiary of SunCoke. Each of SunCoke and SXCP is sending these materials to the SunCoke Stockholders and the SXCP Common Unitholders, as applicable.

These materials are being sent to help SunCoke Stockholders and SXCP Common Unitholders decide how to vote their shares of SunCoke Common Stock or deliver their consent with respect to their SXCP Common Units, as applicable, regarding the matters described herein.

This document constitutes (i) both a proxy statement and prospectus of SunCoke and (ii) a consent statement of SXCP. This document is a proxy statement because the SunCoke Board is soliciting proxies from the SunCoke Stockholders in connection with the approval of the Parent Stock Issuance. This document is a prospectus because SunCoke, in connection with the Merger, is offering SunCoke Common Stock in exchange for outstanding SXCP Public Units. This document is a consent statement because SXCP Common Unitholders are being afforded the opportunity to sign a written consent to the Merger using this document.

Q. What will happen to SXCP as a result of the Merger?

A. If the Merger is successfully completed, Merger Sub will be merged with and into SXCP, with SXCP being the surviving entity in the Merger as an indirect wholly owned subsidiary of SunCoke. In addition, if the Merger is successfully completed, SXCP Common Units will no longer be listed and traded on the New York Stock Exchange (the “NYSE”).

Q. Why are SunCoke and SXCP proposing the Merger?

A. SunCoke and SXCP believe that the Merger will benefit both SunCoke Stockholders and SXCP Common Unitholders. See the sections titled “The Merger—Recommendation of the SunCoke Board and Its Reasons for the Merger” and “The Merger—Recommendations of the SXCP Conflicts Committee and the SXCP Board and Their Reasons for the Merger.”

Q. When will the Merger be completed?

A. SunCoke and SXCP are working to complete the Merger as soon as possible. A number of conditions must be satisfied before SunCoke and SXCP can complete the Merger. Although SunCoke and SXCP cannot be sure when all of the conditions to the Merger will be satisfied, SunCoke and SXCP expect to complete the Merger as soon as practicable following the SunCoke Special Meeting (assuming the Parent Stock Issuance is approved at the SunCoke Special Meeting). See the section titled “The Merger Agreement—Conditions to the Merger.” Assuming timely satisfaction of other closing conditions, including approval of the Parent Stock Issuance at the SunCoke Special Meeting, the Merger is targeted to close in the late second quarter or early third quarter of 2019.

vi

Q. What percentage of outstanding SunCoke Common Stock will SXCP Public Unitholders own after the successful consummation of the Merger?

A. If the Merger is successfully completed, based on the number of shares of SunCoke Common Stock and SXCP Common Units outstanding as of the date of this joint prospectus/consent statement/proxy statement, the shares of SunCoke Common Stock that the SXCP Public Unitholders receive in the Merger will collectively represent approximately [    ]% of the outstanding shares of SunCoke Common Stock following completion of the Merger.

Q. What are the interests in the Merger Transactions of the respective officers and directors of each of SunCoke and SXCP?

A. In considering the recommendations of the SunCoke Board, SunCoke Stockholders should be aware that the executive officers and directors of SunCoke have interests in the Merger Transactions that may differ from, or may be in addition to, the interests of SunCoke Stockholders generally. These interests may present such executive officers and directors with actual or potential conflicts of interests, and these interests, to the extent material, are described in the section titled “The Merger—Interests of Certain Persons in the Merger Transactions.” The SunCoke Board was aware of these interests and considered them, among other matters, prior to providing its approval and recommendation with respect to the Merger Agreement and the transactions contemplated thereby.

In considering the recommendations of the SXCP Conflicts Committee and the SXCP Board, SXCP Common Unitholders should be aware that the executive officers and directors of the SXCP General Partner have interests in the Merger Transactions that may differ from, or may be in addition to, the interests of SXCP Common Unitholders generally. These interests may present such executive officers and directors with actual or potential conflicts of interests, and these interests, to the extent material, are described in the section titled “The Merger—Interests of Certain Persons in the Merger Transactions.” The SXCP Conflicts Committee and the SXCP Board were aware of these interests and considered them, among other matters, prior to providing their respective approvals and recommendations with respect to the Merger Agreement and the transactions contemplated thereby.

Q. Who do I call if I have further questions about the Merger Agreement, the Merger or the Parent Stock Issuance?

A. If SunCoke Stockholders or SXCP Common Unitholders have further questions or if they would like additional copies, without charge, of this document, they may call SunCoke’s or SXCP’s Investor Relations Departments at (630) 824-1907 or (630) 824-1987, respectively, or Morrow Sodali LLC (“Morrow Sodali”), which is acting as SunCoke’s proxy solicitation agent in connection with the SunCoke Special Meeting, at (203) 658-9400 (for banks and brokers) or (toll-free) at (800) 662-5200 (for all others).

Q. What happens if the Merger is not consummated?

A. If for any reason the Merger is not consummated, SXCP Common Units will continue to be listed and traded on the NYSE.

Questions and Answers Specific to SunCoke Stockholders

Q. When and where will the SunCoke Special Meeting be held?

vii

Q. Who is entitled to vote at the SunCoke Special Meeting?

A. If you are a record holder of SunCoke Common Stock as of the close of business on the SunCoke Vote Record Date, you may vote at the SunCoke Special Meeting. See the section titled “The SunCoke Special Meeting of Stockholders.”

Q. Who may attend the SunCoke Special Meeting?

A. SunCoke Stockholders (or their authorized representatives) and SunCoke’s invited guests may attend the SunCoke Special Meeting. All attendees should be prepared to present government-issued photo identification (such as a driver’s license or passport) for admittance.

Q. What are SunCoke Stockholders being asked to vote on at the SunCoke Special Meeting?

A. SunCoke Stockholders are being asked to consider and vote on the Parent Stock Issuance Proposal to approve the Parent Stock Issuance pursuant to the terms of the Merger Agreement in connection with the Merger.

Q. Why is the Parent Stock Issuance, but not the Merger or the Merger Agreement, being considered and voted upon by SunCoke Stockholders?

A. Under Delaware law, a vote of the SunCoke Stockholders is not required to approve the Merger or adopt the Merger Agreement. Under NYSE rules, stockholder approval is required prior to the issuance of SunCoke Common Stock if the number of shares of common stock to be issued equals 20% or more of the number of shares of SunCoke Common Stock outstanding prior to the issuance. The Parent Stock Issuance is expected to result in the issuance of a number of shares of SunCoke Common Stock equal to approximately [    ]% of the shares of SunCoke Common Stock outstanding immediately prior to the effective time of the Merger. Accordingly, SunCoke Stockholders are being asked to consider and vote upon the Parent Stock Issuance.

Q. What vote is required to approve the Parent Stock Issuance Proposal?

A. The approval of the Parent Stock Issuance requires the affirmative vote (in person or by proxy) of the holders of a majority of the aggregate voting power present at the SunCoke Special Meeting or any adjournment or postponement thereof, provided a quorum is present. The Merger will not be completed unless the Parent Stock Issuance Proposal is approved.

Q. What constitutes a quorum for the SunCoke Special Meeting?

A. The presence, in person or by proxy, of SunCoke Stockholders representing a majority of the shares of SunCoke Common Stock outstanding on the SunCoke Vote Record Date will constitute a quorum for the SunCoke Special Meeting.

Q. What are the procedures for adjournment or postponement of the SunCoke Special Meeting?

A. The Chairman of the SunCoke Board or the President of SunCoke may adjourn the SunCoke Special Meeting from time to time, whether or not there is a quorum. No notice of the time and place of adjourned meetings need be given except as required by law. The SunCoke Special Meeting may be postponed or canceled by resolution of the SunCoke Board upon public notice given prior to the date of the SunCoke Special Meeting.

Q. What if I do not vote my SunCoke Common Stock or if I abstain from voting?

A. The approval of the Parent Stock Issuance Proposal requires the affirmative vote (in person or by proxy) of the holders of a majority of the aggregate voting power present at the SunCoke Special Meeting or any adjournment

viii

or postponement thereof, provided a quorum is present. If you abstain from voting on the Parent Stock Issuance Proposal, your shares of SunCoke Common Stock will be counted as present for purposes of establishing a quorum, but the abstention will not be counted as a vote cast either “FOR” or “AGAINST” the Parent Stock Issuance Proposal.

The obligations of the parties to complete the Merger are conditioned upon the Parent Stock Issuance Approval. Accordingly, a vote against or an abstention with respect to the Parent Stock Issuance Proposal, or a failure to vote on the Parent Stock Issuance Proposal, to the extent such failure prevents the establishment of a quorum, will have the same effect as a vote against the Parent Stock Issuance Proposal and the Merger (although no vote “FOR” or “AGAINST” the Merger is taking place).

Q. How does the SunCoke Board recommend that the SunCoke Stockholders vote?

A. The SunCoke Board recommends that SunCoke Stockholders vote “FOR” the Parent Stock Issuance Proposal.

On February 4, 2019, the SunCoke Board (i) determined that the Merger Agreement and the transactions contemplated thereby, including the Merger and the Parent Stock Issuance, are in the best interests of SunCoke and its stockholders, (ii) approved and declared advisable the Merger Agreement and the transactions contemplated thereby, including the Merger and the Parent Stock Issuance, and (iii) resolved to submit the Parent Stock Issuance to a vote of SunCoke’s stockholders. The SunCoke Board hereby recommends that you vote “FOR” the Parent Stock Issuance Proposal. For more information regarding the recommendation of the SunCoke Board, see the section titled “The Merger—Recommendation of the SunCoke Board and Its Reasons for the Merger.”

In considering the recommendation of the SunCoke Board, SunCoke Stockholders should consider that the executive officers and directors of SunCoke may have interests that differ from, or are in addition to, their interests as SunCoke Stockholders. See the section titled “The Merger—Interests of Certain Persons in the Merger Transactions.”

Q. How do I submit my proxy for the SunCoke Special Meeting?

A. If you are a stockholder of record, you may submit a proxy via the Internet, by phone, or by mail. If you hold your SunCoke Common Stock in “street name” with a broker, bank or other nominee, you should follow the instructions provided by your broker, bank or other nominee. See the section titled “The SunCoke Special Meeting of Stockholders.”

Q. How many votes do I have?

A. SunCoke Stockholders have one vote per share of SunCoke Common Stock.

Q. What should I do if I receive more than one set of voting materials for the SunCoke Special Meeting?

A. You may receive more than one set of voting materials for the SunCoke Special Meeting and the materials may include multiple proxy cards or voting instruction cards. For example, you will receive a separate set of voting materials for each brokerage account in which you hold SunCoke Common Stock. Additionally, if you are a holder of record registered in more than one name, you will receive more than one set of voting materials. Please complete, sign, date and return each proxy card according to the instructions on it.

ix

Q. If my shares of SunCoke Common Stock are held in street name by my bank, broker or other nominee, will my bank, broker or other nominee automatically vote my shares for me?

A. No. If your shares of SunCoke Common Stock are held in street name, you must instruct the broker, bank or other nominee on how to vote your shares. See the section titled “The SunCoke Special Meeting of Stockholders.”

Q. If I am planning to attend the SunCoke Special Meeting in person, should I still vote by proxy?

A. Yes. Whether or not you plan to attend the SunCoke Special Meeting, you should vote by proxy. Your SunCoke shares will not be voted if you do not vote by proxy or do not vote in person at the SunCoke Special Meeting.

Q. What happens if I sell my SunCoke Common Stock after the SunCoke Vote Record Date but before the SunCoke Special Meeting?

A. If you transfer shares of your SunCoke Common Stock after the SunCoke Vote Record Date but before the date of the SunCoke Special Meeting, you will retain your right to vote at the SunCoke Special Meeting.

Q. May I change my vote after I have delivered my proxy card?

A. Yes. If you are a stockholder of record, you can change your vote within the regular voting deadlines by voting again by telephone or via the Internet, executing and returning a later dated proxy card, attending the annual meeting and voting in person, or by delivering a written notice of your revocation to SunCoke’s Corporate Secretary at 1011 Warrenville Road, Suite 600, Lisle, IL 60532. If you hold your SunCoke Common Stock in street name, you should follow the instructions provided by your banker, broker or other nominee. See the section titled “The SunCoke Special Meeting of Stockholders.”

Q. What will SunCoke Stockholders receive in the Merger?

A. SunCoke Stockholders will retain the SunCoke Common Stock they currently own, but will not receive any additional SunCoke Common Stock in the Merger. SunCoke expects that the Merger will simplify SunCoke’s organizational structure and create a larger public float, which is anticipated to result in enhanced trading liquidity, a lower cost of capital, improved consolidated credit metrics, and better access to, and cost of, debt financing. See the section titled “The Merger—Recommendations of the SunCoke Board and Its Reasons for the Merger.”

Questions and Answers Specific to SXCP Common Unitholders

Q. Who is entitled to give written consent with respect to the Merger?

A. If you are a record holder of SXCP Common Units as of the close of business on the SXCP Record Date, you may give written consent with respect to the Merger by filling out the enclosed written consent, dating and signing it, and then promptly delivering it to SXCP by one of the means described in the section entitled “Written Consents of Holders of SXCP Common Units—Submission of Consents.” SXCP does not intend to hold a meeting of SXCP Common Unitholders to consider the Merger Agreement and the Merger.

Q. Can holders of SXCP Common Units change or revoke their written consents?

A. Yes. If you are a record holder of SXCP Common Units on the SXCP Record Date, you may revoke your consent or, if you have previously revoked your consent, submit a new written consent at any time before the consents of a sufficient number of SXCP Common Units to approve the Merger Agreement have been delivered to the Corporate Secretary of SXCP. If you wish to change or revoke your consent before that time, you may do so by sending in a new written consent with a later date by one of the means described in the section entitled

x

“Written Consents of Holders of SXCP Common Units—Submission of Consents,” or delivering a notice of revocation to the Corporate Secretary of SXCP.

Q. What SXCP Common Unitholder approval is required to adopt the Merger Agreement?

A. The approval and adoption of the Merger Agreement and the Merger by SXCP requires the affirmative vote or consent of holders of at least a majority of the outstanding SXCP Common Units. Pursuant to the terms of the Support Agreement, SC&C, a wholly owned subsidiary of SunCoke which as of February 4, 2019 beneficially owned 28,499,899 SXCP Common Units representing approximately 61.7% of the outstanding SXCP Common Units, has agreed to deliver the SC&C Written Consent within two business days after the effectiveness of the registration statement of which this joint prospectus/consent statement/proxy statement forms a part. The delivery of the SC&C Written Consent by SC&C will be sufficient to adopt the Merger Agreement and thereby approve the Merger on behalf of SXCP.

Q. Should SXCP Public Unitholders deliver their SXCP Common Units now?

A. No. After the Merger is completed, SXCP Public Unitholders who hold their SXCP Common Units in certificated or book entry form will receive written instructions for exchanging their SXCP Common Units. If you own SXCP Common Units in street name, the shares of SunCoke Common Stock you will receive in connection with the Merger should be credited to your account in accordance with the policies and procedures of your bank, broker or other nominee within a few days following the closing date of the Merger.

Q. What will SXCP Public Unitholders be entitled to receive in the Merger?

A. Each SXCP Public Unitholder will be entitled to receive SunCoke Common Stock in exchange for such holder’s SXCP Public Units at the Exchange Ratio. Each SXCP Public Unitholder will also be entitled to receive, with respect to each SXCP Public Unit held by such holder, a fraction of a share of SunCoke Common Stock equal to the product of (aa) the number of days beginning with the first day of the most recent full calendar quarter with respect to which an SXCP unitholder distribution record date has not occurred (or, if there is no such full calendar quarter, then beginning with the first day of the partial calendar quarter in which the Closing occurs), and ending on the day immediately prior to the Closing, multiplied by (bb) a daily distribution rate that is equal to the quotient of the most recent regular quarterly cash distribution paid by SXCP divided by 90, such product divided by $10.91, which was the closing price of the SunCoke Common Stock as of February 1, 2019, the last full trading day prior to the date of the execution of the Merger Agreement. For additional information regarding exchange procedures, please read “The Merger Agreement—Exchange of Units; Fractional Share Proceeds.”

Q. Where will SXCP Common Units trade after the Merger?

A. SXCP Common Units will no longer be publicly traded following the Merger and will be delisted from the NYSE.

Q. What happens to future distributions with respect to SXCP Public Units?

A. If the Merger is successfully consummated, all outstanding SXCP Public Units (i) will be converted into the right to receive the Merger Consideration and (ii) will no longer receive quarterly distributions from SXCP. For a description of the differences between the rights of holders of SunCoke Common Stock and holders of SXCP Common Units, please read “Comparison of the Rights of SunCoke Stockholders and SXCP Common Unitholders.”

Q. What will happen to SXCP’s outstanding senior notes and secured credit facility as a result of the Merger?

A. SXCP’s currently outstanding senior notes will remain outstanding after the Merger is completed, and no “change of control” will occur thereunder. SXCP’s currently outstanding secured credit facility will remain in effect after the Merger is completed, and no “change of control” will occur thereunder.

Q. What are the expected U.S. federal income tax consequences to an SXCP Public Unitholder as a result of the Merger?

A. The receipt of SunCoke Common Stock and any cash in lieu of fractional shares of SunCoke Common Stock in exchange for SXCP Public Units pursuant to the Merger should be a taxable transaction to U.S. holders (as defined in the section titled “Material U.S. Federal Income Tax Consequences”) for U.S. federal income tax purposes. In such case, a U.S. holder will generally recognize capital gain or loss on the receipt of SunCoke Common Stock and any cash received in lieu of fractional shares of SunCoke Common Stock in exchange for SXCP Public Units. However, a portion of this gain or loss, which portion could be substantial, will be separately computed and taxed as ordinary income or loss to the extent attributable to assets giving rise to depreciation recapture or other “unrealized receivables” or to “inventory items” owned by SXCP and its subsidiaries. Passive losses that were not deductible by a U.S. holder in prior taxable periods because they exceeded a U.S. holder’s share of SXCP’s income may become available to offset a portion of the gain recognized by such U.S. holder. See the section titled “Material U.S. Federal Income Tax Consequences” for a more complete discussion of certain U.S. federal income tax consequences of the Merger.

Q. What are the expected U.S. federal income tax consequences for an SXCP Public Unitholder of the ownership of shares of SunCoke Common Stock after the Merger is completed?

A. SunCoke is classified as a corporation for U.S. federal income tax purposes, and thus, SunCoke (and not its stockholders) is subject to U.S. federal income tax on its taxable income. A distribution of cash by SunCoke to a stockholder who is a U.S. holder (as defined in the section titled “Material U.S. Federal Income Tax Consequences”) will generally be included in such U.S. holder’s income as ordinary dividend income to the extent of SunCoke’s current or accumulated “earnings and profits” as determined under U.S. federal income tax principles. Any portion of the cash distributed to SunCoke Stockholders by SunCoke after the Merger that exceeds SunCoke’s current and accumulated earnings and profits will be treated as a non-taxable return of capital reducing a U.S. holder’s adjusted tax basis in such U.S. holder’s shares of SunCoke Common Stock and, to the extent the distribution exceeds such stockholder’s adjusted tax basis, as capital gain from the sale or exchange of such shares of SunCoke Common Stock. See the section titled “Material U.S. Federal Income Tax Consequences” for a more complete discussion of certain U.S. federal income tax consequences of owning and disposing of shares of SunCoke Common Stock.

Q. Are SXCP Common Unitholders entitled to appraisal rights in connection with the Merger?

A. No. SXCP Common Unitholders do not have appraisal rights under applicable law or contractual appraisal rights under the SXCP Partnership Agreement or the Merger Agreement.

Historical consolidated financial data as of December 31, 2016, 2015 and 2014 and for each of the years ended December 31, 2015 and 2014 are derived from SunCoke’s consolidated financial statements not incorporated by reference into this joint prospectus/consent statement/proxy statement. It should not be assumed the results of operations for any past period indicate results for any future period.

The selected historical financial information presented for SXCP as of December 31, 2018 and 2017 and for each of the years ended December 31, 2018, 2017 and 2016, was derived from the audited consolidated financial statements of SXCP included in SXCP’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018, which is incorporated by reference in this joint prospectus/consent statement/proxy statement. Historical consolidated financial data as of December 31, 2016, 2015 and 2014 and for each of the years ended December 31, 2015 and 2014 are derived from SXCP’s consolidated financial statements not incorporated by reference into this joint prospectus/consent statement/proxy statement. It should not be assumed the results of operations for any past period indicate results for any future period.

You should read the financial information with respect to SunCoke presented below in conjunction with the historical consolidated financial statements, the related notes, and the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in SunCoke’s Annual Report on Form 10-K for the year ended December 31, 2018. You should read the financial information with respect to SXCP presented below in conjunction with the historical consolidated financial statements, the related notes, and the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in SXCP’s Annual Report on Form 10-K for the year ended December 31, 2018. See the section titled “Documents Incorporated by Reference.”

The selected unaudited pro forma financial information shows the pro forma effect of SunCoke’s acquisition of the publicly held noncontrolling interest in SXCP as a result of the Merger and has been provided to assist in the analysis of the financial effects of the Merger. The selected unaudited pro forma condensed consolidated financial statements of SunCoke, from which the selected unaudited pro forma financial information is derived, are presented beginning on page F-2 of this document. The unaudited pro forma condensed consolidated statement of income for the year ended December 31, 2018 assumes the Merger occurred on January 1, 2018. The unaudited pro forma condensed consolidated balance sheet as of December 31, 2018 assumes the Merger occurred on December 31, 2018. The unaudited pro forma condensed consolidated financial statements are provided for illustrative purposes only and do not purport to represent what SunCoke’s actual results of operations or financial position would have been if the Merger had occurred on the dates assumed, nor are they necessarily indicative of SunCoke’s future operating results or financial position. However, the pro forma adjustments shown in the unaudited pro forma condensed consolidated financial statements reflect estimates and assumptions that SunCoke management believes to be reasonable. For a complete discussion of the pro forma adjustments underlying the amounts in the tables below, please read “Unaudited Pro Forma Condensed Consolidated Financial Statements” beginning on page F-2 of this document.

COMPARATIVE AND PRO FORMA PER SHARE/UNIT DATA

The following table presents SunCoke’s and SXCP’s historical per share/unit data, per share pro forma data for SunCoke and equivalent per unit pro forma data for SXCP, using certain assumptions as set forth in the footnotes to the table. The data do not purport to be indicative of: (1) the results of operations or financial position which would have been achieved if the Merger had been effected at the beginning of the period or as of the date indicated or (2) the results of operations or financial position that may be achieved in the future.

16

SunCoke management intends to recommend to its Board of Directors a quarterly dividend on the SunCoke Common Stock of approximately $0.06 per share (an annualized dividend of $0.24 per share) beginning in the first full quarter immediately following the completion of the Merger. As such, the pro forma adjustment to dividends declared per share for the year ended December 31, 2018 would have been $0.24 per share rather than the $0.3170 per share shown above.

17

MARKET PRICE AND CASH DISTRIBUTION INFORMATION

SunCoke Common Stock and SXCP Common Units are each listed on the New York Stock Exchange (the “NYSE”) under the symbols “SXC” and “SXCP,” respectively. The following table sets forth for the periods indicated the high and low per-share and per-unit sales price of SunCoke Common Stock and SXCP Common Units, respectively, and the cash dividends per share and cash distributions per unit of SunCoke Common Stock and SXCP Common Units, respectively, for each of the last two fiscal years and the current fiscal year.

On February 4, 2019, the last full trading day prior to the public announcement of the proposed Merger, the closing price for each share of SunCoke Common Stock as reported on the NYSE was $10.93 and the closing price for each SXCP Common Unit as reported on the NYSE was $14.00. On April 9, 2019, the last practicable trading day prior to the filing date of this joint prospectus/consent statement/proxy statement, the closing price for each share of SunCoke Common Stock as reported on the NYSE was $8.88 and the closing price for each SXCP Common Unit as reported on the NYSE was $12.93.

As of April 9, 2019, there were approximately 10,463 record holders of SunCoke Common Stock and six record holders of SXCP Common Units.

No assurance can be given concerning the market price for SunCoke Common Stock before or after the Merger. The market price for SunCoke Common Stock will fluctuate between the date of this joint prospectus/consent statement/proxy statement and the date on which the Merger is consummated and thereafter.

The SXCP Partnership Agreement provides that SXCP will distribute its cash available for distributions, if any, to SXCP Common Unitholders of record on the applicable record date (such distributions are more fully described in the section titled “Comparison of the Rights of SunCoke Stockholders and SXCP Common Unitholders”). As a result of the conversion and cancellation of SXCP Common Units in connection with the Merger, SXCP will no longer make quarterly distributions following the consummation of the Merger.

The Merger Agreement restricts the ability of SunCoke to, prior to the consummation of the Merger, declare, set aside or pay any dividend or distribution payable in cash, stock, or property in respect of any capital stock, other than regular quarterly cash dividends or distributions that have a record date after the effective time of the Merger. See the section titled “The Merger Agreement—Covenants and Other Agreements.”

RISK FACTORS

You should carefully consider the following risk factors, together with all of the other information in this joint prospectus/consent statement/proxy statement, the documents incorporated herein by reference and the documents to which you are referred herein. In particular, please read Part I, Item 1A, “Risk Factors,” in SunCoke’s Annual Report on Form 10-K for the year ended December 31, 2018 and SXCP’s Annual Report on Form 10-K for the year ended December 31, 2018, each of which is incorporated by reference herein. Each of these factors could adversely affect the consummation of the Merger, SunCoke’s and SXCP’s respective businesses, operating results and financial conditions, and the value of an investment in SunCoke Common Stock. This joint prospectus/consent statement/proxy statement also contains forward-looking statements that involve risks and uncertainties. Please read “Information Regarding Forward-Looking Statements.”

Risks Related to the Merger

The Merger is subject to closing conditions that, if not satisfied or waived, will result in the Merger not being consummated, which may cause the market price of SXCP Common Units and/or SunCoke Common Stock to decline.

The obligation of the parties to the Merger Agreement to complete the Merger is subject to the satisfaction or waiver of certain conditions, including:

The parties’ obligations are also separately subject to the satisfaction or waiver of the following conditions:

19

If these conditions are not satisfied or waived, the Merger will not occur, which may cause the market price of SXCP Common Units and/or SunCoke Common Stock to decline.

Financial projections regarding SXCP and SunCoke may not be realized.

Certain internal financial information and forecasts for SXCP and SunCoke were prepared by employees of SunCoke, including those who normally render services to SXCP. These financial projections include assumptions regarding future operating cash flows, expenditures and income of SXCP and SunCoke. These financial projections were not prepared with a view to public disclosure, are subject to significant economic, competitive, industry and other uncertainties, and may not be achieved in full, at all, or within projected timeframes. The failure of SXCP’s or SunCoke’s businesses to achieve projected results, including projected cash flows, could have a material adverse effect on the price of SunCoke Common Stock, SunCoke’s financial position and SunCoke’s ability to reinstate, maintain or increase its dividends following the Merger.

The unaudited pro forma financial statements included in this joint prospectus/consent statement/proxy statement are presented for illustrative purposes only and may not be an indication of the combined entity’s financial condition or results of operations following the Merger.

The unaudited pro forma financial statements contained in this joint prospectus/consent statement/proxy statement are presented for illustrative purposes only, are based on various adjustments, assumptions and preliminary estimates and may not be an indication of the financial condition or results of operations of the combined entity following the Merger for several reasons. The actual financial condition and results of operations of the combined entity following the Merger may not be consistent with, or evident from, these pro forma financial statements. In addition, the assumptions used in preparing the pro forma financial information may not prove to be accurate, and other factors may affect the financial condition or results of operations of the combined entity following the Merger. Any potential decline in the financial condition or results of operations of the combined entity may cause significant variations in the price of SunCoke Common Stock after completion of the Merger. See the section titled “The Merger – Unaudited Financial Projections of SunCoke and SXCP.”

The number of shares of SunCoke Common Stock that SXCP Public Unitholders will be entitled to receive in the Merger is based upon the Exchange Ratio, which is a fixed exchange ratio. As a result, the market value of the shares of SunCoke Common Stock that SXCP Public Unitholders receive for their SXCP Public Units in the Merger could decrease prior to the consummation of the Merger.

The Exchange Ratio is fixed, meaning that it does not change and is not dependent upon the relative values of SXCP Public Units and SunCoke Common Stock. Therefore, there is no “price protection” mechanism contained in the Merger Agreement that would adjust the number of shares of SunCoke Common Stock that SXCP Public Unitholders will receive based on any decreases in the trading price of SunCoke Common Stock or increases in the trading price of SXCP Common Units. If the price of SunCoke Common Stock decreases because of changes in SunCoke’s business, operations, or prospects, market reactions to the Merger, general market and economic conditions, or any other factors, such as an announcement by SunCoke that it will pursue another merger or acquisition or an equity or debt offering, the market value of the shares of SunCoke Common Stock received by SXCP Public Unitholders will also decrease. Consistent with the Merger Agreement, if SunCoke engages in any such transactions and the market price of SunCoke Common Stock declines in value as a result, SXCP Public Unitholders will receive less value for their SXCP Public Units than the value calculated pursuant to the Exchange Ratio on the date the Merger was announced. For historical and current market prices of SXCP Common Units and SunCoke Common Stock, please read the “Market Price and Cash Distribution Information” section of this joint prospectus/consent statement/proxy statement.

20

The SXCP Partnership Agreement limits the duties of the SXCP General Partner to SXCP Common Unitholders and restricts the remedies available to SXCP Common Unitholders for actions taken by the SXCP General Partner that might otherwise constitute breaches of its duties.

Under the SXCP Partnership Agreement, whenever a potential conflict of interest exists or arises between the SXCP General Partner or any of its affiliates, on the one hand, and SXCP, its subsidiaries, any partner of SXCP or any other person who acquires an interest in SXCP or any other person who is bound by the SXCP Partnership Agreement, on the other hand, the SXCP General Partner may in its discretion submit any resolution or course of action with respect to such conflict of interest for “Special Approval” or approval by the vote of a majority of the SXCP Common Units (excluding SXCP Common Units owned by SXCP General Partner and its affiliates). If such course of action or resolution receives Special Approval or approval of a majority of the SXCP Common Units (excluding SXCP Common Units owned by SXCP General Partner and its affiliates), then such course of action or resolution will be conclusively deemed approved by SXCP, all of its partners, each person who acquires an interest in SXCP and each other person who is bound by the SXCP Partnership Agreement, and will not constitute a breach of the SXCP Partnership Agreement or any governing agreement of any of SXCP’s subsidiaries or any fiduciary or other duty existing at law, in equity or otherwise.

For more information concerning the differing applications of duties to corporations and limited partnerships, please read “Comparison of the Rights of SunCoke Stockholders and SXCP Common Unitholders—Fiduciary Duties; Conflicts of Interest” beginning at page 105.

In light of potential conflicts of interest between SunCoke and the SXCP General Partner, on the one hand, and SXCP and the SXCP Public Unitholders, on the other hand, the SXCP Board submitted the Merger and related matters to the SXCP Conflicts Committee for Special Approval.

The SXCP Conflicts Committee reviewed, negotiated and evaluated the Merger Agreement, the Support Agreement, the Merger and related matters on behalf of SXCP and the SXCP Public Unitholders. The SXCP Conflicts Committee, by a unanimous vote held on February 4, 2019, (i) determined that the Merger Agreement and the transactions contemplated thereby are in the best interest of SXCP, including the holders of SXCP Public Units, (ii) approved the Merger Agreement and the transactions contemplated thereby, including the Merger (the foregoing constituting SXCP Special Approval under the SXCP Partnership Agreement), and (iii) recommended that the SXCP Board approve the Merger Agreement and the consummation of the transactions contemplated thereby, including the Merger. As described above, the duties of the SXCP General Partner, the SXCP Board and the SXCP Conflicts Committee to SXCP Common Unitholders in connection with the Merger are substantially limited by the SXCP Partnership Agreement.

The executive officers and directors of SunCoke may have interests that differ in certain respects from those of the SunCoke Stockholders.

In considering the SunCoke Board’s recommendation to approve the Parent Stock Issuance at the SunCoke Special Meeting (such recommendation, the “SunCoke Board Recommendation”), the SunCoke Stockholders should consider that the executive officers and directors of SunCoke may have interests that differ from, or are in addition to, their interests as SunCoke Stockholders. See the section titled “The Merger—Interests of Certain Persons in the Merger Transactions.”

SunCoke and SXCP will incur transaction-related costs in connection with the Merger.

SunCoke and SXCP expect to incur a number of non-recurring transaction-related costs associated with completing the Merger, which are currently estimated to total approximately $[    ] million. Non-recurring transaction costs include, but are not limited to, fees paid to legal, financial, and accounting advisors, filing fees, and printing costs. There can be no assurance that the elimination of certain costs as a result of the Merger will offset the incremental transaction-related costs over time. Thus, any net cost savings may not be achieved in the near term, the long term or at all.

21

Under the Merger Agreement, if the Merger Agreement is terminated under certain specified circumstances, SunCoke would be required to pay SXCP’s expenses and, under certain circumstances, a termination fee.

The Merger Agreement contains provisions granting both SunCoke and SXCP the right to terminate the Merger Agreement for certain reasons, including, among others, if: (i) the Merger is not completed on or before September 30, 2019 (the “Termination Date”); (ii) any governmental authority has issued an order, decree or ruling or taken any other action (including the enactment of any statute, rule, regulation, decree or executive order) permanently restraining, enjoining or otherwise prohibiting the Merger; (iii) the SunCoke Special Meeting shall have concluded and the Parent Stock Issuance shall not have been approved; or (iv) under certain conditions, there has been a material breach of any of the representations, warranties, covenants or agreements set forth in the Merger Agreement by a party to the Merger Agreement that is not cured prior to the Termination Date. The Merger Agreement further provides that upon termination of the Merger Agreement under certain circumstances, SunCoke may be required to either (1) pay SXCP a termination fee of $6 million and/or (2) reimburse SXCP for its transaction expenses.

These provisions could discourage third parties that may have interest in acquiring all or a significant part of SunCoke from considering or proposing such an acquisition, or could result in a potential acquirer of SunCoke proposing to pay a lower price than it would otherwise have proposed to pay. See the sections titled “The Merger Agreement—SunCoke Board Recommendation and SunCoke Adverse Recommendation Change,” “The Merger Agreement—Termination,” and “The Merger Agreement—Expense Reimbursement and Termination Fee.”

SXCP has no ability to enter into a transaction that is not approved by the SXCP General Partner, which is controlled by SunCoke.

SunCoke controls the SXCP General Partner, which in turn controls SXCP. Accordingly, any transaction entered into by SXCP would need to be approved by the SXCP General Partner. Because SunCoke controls the SXCP General Partner, SunCoke could effectively block SXCP from entering into any transaction that SunCoke does not support.

Tax Risks Related to the Merger and the Ownership of SunCoke Common Stock Received in the Merger

In addition to reading the following risk factors, you are urged to read “Material U.S. Federal Income Tax Consequences” for a more complete discussion of the expected U.S. federal income tax consequences of the Merger and owning and disposing of SunCoke Common Stock received in the Merger.

The Merger should be a taxable transaction and, in such case, the resulting tax liability of an SXCP Public Unitholder, if any, will depend on such unitholder’s particular situation.

SXCP Public Unitholders will receive SunCoke Common Stock and cash in lieu of fractional shares, if any, in exchange for their SXCP Public Units. Although SXCP Public Unitholders will receive no cash consideration other than any cash received in lieu of fractional shares, if any, the Merger should be treated as a taxable sale by SXCP Public Unitholders for U.S. federal income tax purposes. In such case, as a result of the Merger, an SXCP Public Unitholder will recognize gain or loss for U.S. federal income tax purposes equal to the difference between such unitholder’s amount realized and the unitholder’s adjusted tax basis in the SXCP Public Units. The amount of gain or loss recognized by each SXCP Public Unitholder in the Merger will vary depending on each unitholder’s particular situation, including the value of the shares of SunCoke Common Stock and the amount of cash in lieu of fractional shares, if any, received by each unitholder in the Merger, the adjusted tax basis of the SXCP Public Units exchanged by each unitholder in the Merger, and the amount of any suspended passive losses that may be available to a particular unitholder to offset a portion of the gain recognized by the unitholder. You are strongly urged to consult your tax advisor for a full understanding of the particular tax consequences of the Merger to you.

22

The tax liability of an SXCP Public Unitholder as a result of the Merger could be more than expected.

Because the value of any SunCoke Common Stock received in the Merger will not be known until the effective time of the Merger, an SXCP Public Unitholder will not be able to determine its amount realized, and therefore its taxable gain or loss, until such time. In addition, because prior distributions in excess of an SXCP Public Unitholder’s allocable share of SXCP’s net taxable income decrease such SXCP Public Unitholder’s tax basis in its SXCP Public Units, the amount, if any, of such prior excess distributions with respect to such SXCP Public Units will, in effect, become taxable income to an SXCP Public Unitholder if the aggregate value of the consideration received in the Merger is greater than such SXCP Public Unitholder’s adjusted tax basis in its SXCP Public Units, even if the aggregate value of the consideration received in the Merger is less than such SXCP Public Unitholder’s original cost basis in its SXCP Public Units. Furthermore, a portion of this gain or loss, which portion could be substantial, will be separately computed and taxed as ordinary income or loss to the extent attributable to assets giving rise to depreciation recapture or other “unrealized receivables” or to “inventory items” owned by SXCP and its subsidiaries.

For a more complete discussion of certain U.S. federal income tax consequences of the Merger, please read “Material U.S. Federal Income Tax Consequences.”

The U.S. federal income tax treatment to SXCP Public Unitholders with respect to owning and disposing of any shares of SunCoke Common Stock received in the Merger will be different than their U.S. federal income tax treatment with respect to owning and disposing of their SXCP Public Units.

SXCP is classified as a partnership for U.S. federal income tax purposes and, generally, is not subject to entity-level U.S. federal income taxes. Instead, each SXCP Public Unitholder is required to take into account such unitholder’s share of items of income, gain, loss, and deduction of SXCP in computing its U.S. federal income tax liability, regardless of whether cash distributions are made to such SXCP Public Unitholder by SXCP. A distribution of cash by SXCP to an SXCP Public Unitholder who is a U.S. holder (as defined in the section titled “Material U.S. Federal Income Tax Consequences”) is generally not taxable for U.S. federal income tax purposes unless the amount of cash distributed is in excess of the SXCP Public Unitholder’s adjusted tax basis in its SXCP Public Units. In contrast, SunCoke is classified as a corporation for U.S. federal income tax purposes, and thus, SunCoke (and not its stockholders) is subject to U.S. federal income tax on its taxable income. A distribution of cash by SunCoke to a stockholder who is a U.S. holder will generally be included in such U.S. holder’s income as ordinary dividend income to the extent of SunCoke’s current or accumulated “earnings and profits,” as determined under U.S. federal income tax principles. A portion of the cash distributed to SunCoke Stockholders by SunCoke after the Merger may exceed SunCoke’s current and accumulated earnings and profits. Cash distributions in excess of SunCoke’s current and accumulated earnings and profits will be treated as a non-taxable return of capital, reducing a U.S. holder’s adjusted tax basis in such stockholder’s SunCoke Common Stock and, to the extent the cash distribution exceeds such stockholder’s adjusted tax basis, as gain from the sale or exchange of such shares of SunCoke Common Stock.

Please read “Material U.S. Federal Income Tax Consequences” for a more complete discussion of certain U.S. federal income tax consequences of owning and disposing of SunCoke Common Stock.

Risks Inherent in an Investment in SunCoke

The SunCoke Common Stock to be received by SXCP Public Unitholders as a result of the Merger has different rights from SXCP Common Units.

Following completion of the merger, SXCP Public Unitholders will no longer hold SXCP Common Units, but will instead hold shares of SunCoke Common Stock. SunCoke is a corporation and SXCP is a limited partnership. There are important differences between the rights of SXCP Common Unitholders and the rights of SunCoke Stockholders. See the section titled “Comparison of the Rights of SunCoke Stockholders and SXCP Common Unitholders” for a discussion of the different rights associated with SXCP Common Units and SunCoke Common Stock.

23

SunCoke may only declare and pay dividends in accordance with the DGCL.

Under the General Corporation Law of the State of Delaware (the “DGCL”), the SunCoke Board may not authorize payment of a dividend unless it is either (i) paid out of surplus, as calculated in accordance with the DGCL, or (ii) if SunCoke does not have a surplus, paid out of net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. If SunCoke is unable to authorize payment of dividends in accordance with the DGCL, a decline in the market price or liquidity, or both, of the SunCoke Common Stock could result. This may in turn result in losses by SunCoke Stockholders.

The price of SunCoke Common Stock may be volatile, and holders of SunCoke Common Stock could lose a significant portion of their assets.

The market price of SunCoke Common Stock could be volatile, and SunCoke Stockholders may not be able to resell their shares of SunCoke Common Stock at or above the price at which they acquired such shares of SunCoke Common Stock due to fluctuations in the market price of SunCoke Common Stock, including changes in price caused by factors unrelated to SunCoke’s operating performance or prospects.

Specific factors that may have a significant effect on the market price for SunCoke Common Stock include:

SunCoke’s amended and restated bylaws (the “SunCoke Bylaws”) include a forum selection clause, which could limit a SunCoke Stockholder’s ability to obtain a favorable judicial forum for disputes with SunCoke.

The SunCoke Bylaws provide that unless SunCoke consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or other state court located within the State of Delaware or, if no state court located within the State of Delaware has jurisdiction, then the federal district court for the District of Delaware) shall be the sole and exclusive forum for: (i) any derivative action or proceeding brought on behalf of SunCoke, (ii) any action asserting a claim of breach of fiduciary duty owed by any director or officer or other employee of SunCoke to SunCoke or SunCoke Stockholders, (iii) any action asserting a claim against SunCoke or any director or officer or other employee of SunCoke arising pursuant to any provision of the DGCL, the amended and restated certificate of incorporation of SunCoke (the “SunCoke Certificate,” and together with the SunCoke Bylaws, the “SunCoke Organizational Documents”) or the SunCoke Bylaws (as either may be amended from time to time), or (iv) any action asserting a claim against SunCoke or any director or officer or other employee of SunCoke governed by the internal affairs doctrine. Any person or entity purchasing or otherwise acquiring any interest in SunCoke Common Stock is deemed to have notice of and consented to the

24

foregoing provisions. This forum selection provision may limit a SunCoke Stockholder’s ability to obtain a favorable judicial forum for disputes with SunCoke. It is also possible that, notwithstanding the forum selection clause in the SunCoke Bylaws, a court could rule that such a provision is inapplicable or unenforceable. See the section titled ‘‘Description of SunCoke Common Stock—Exclusive Forum.’’ The forum selection provision does not apply to a cause of action brought under federal or state securities laws.

25

WRITTEN CONSENTS OF HOLDERS OF SXCP COMMON UNITS

SXCP Common Units Entitled to Consent and Consent Required

Only SXCP Common Unitholders of record at the close of business on the SXCP Record Date of                     , 2019 will be notified of and be entitled to execute and deliver a written consent with respect to the Merger Agreement and the Merger. The approval and adoption of the Merger Agreement and the Merger by SXCP requires the affirmative vote or consent of holders of a majority of the outstanding SXCP Common Units.

Pursuant to the terms of the Support Agreement, SC&C, which as of February 4, 2019 beneficially owned 28,499,899 SXCP Common Units representing approximately 61.7% of the outstanding SXCP Common Units, has irrevocably agreed to deliver the SC&C Written Consent adopting and approving in all respects the Merger Agreement and the transactions contemplated thereby, including the Merger, within two business days after the effectiveness of the registration statement of which this joint prospectus/consent statement/proxy statement forms a part. The delivery of the SC&C Written Consent by SC&C with respect to the SXCP Common Units it owns will be sufficient to approve the Merger Agreement and the Merger on behalf of SXCP.

Submission of Consents

Holders of SXCP Common Units may consent to the approval and adoption of the Merger Agreement and the Merger with respect to their SXCP Common Units by completing, dating and signing the written consent furnished with this joint prospectus/consent statement/proxy statement and returning it to SXCP.

If you are a SXCP Unitholder of record at the close of business on the SXCP Record Date and you wish to give your written consent, you must fill out the enclosed written consent, date and sign it, and return it to SXCP by following the instructions in the next sentence. Once you have completed, dated and signed the written consent, you may deliver it to SXCP by faxing it to SunCoke Energy Partners, L.P., Attention: Corporate Secretary, at 630-824-1185, or by mailing your written consent to SunCoke Energy Partners, L.P., 1011 Warrenville Road, Suite 600, Lisle, IL 60532, Attention: Corporate Secretary.

Once a sufficient number of consents to approve and adopt the Merger Agreement and the transactions contemplated thereby, including the Merger, have been received, the consent process will conclude. The delivery of the SC&C Written Consent with respect to the SXCP Common Units owned by SC&C approving the Merger Agreement will be sufficient to approve the Merger Agreement and the Merger on behalf of SXCP.

Revocation of Consents

Your consent may be revoked at any time before the consents of a sufficient number of SXCP Common Units to approve the adoption of the Merger Agreement and the transactions contemplated thereby, including the Merger, have been delivered to the Corporate Secretary of SXCP. If you wish to revoke a previously given consent before that time, you may do so by faxing such revocation to SunCoke Energy Partners, L.P., Attention: Corporate Secretary, at 630-824-1185, or by mailing your written consent to SunCoke Energy Partners, L.P., 1011 Warrenville Road, Suite 600, Lisle, IL 60532, Attention: Corporate Secretary.

THE SUNCOKE SPECIAL MEETING OF STOCKHOLDERS

SunCoke is providing this joint prospectus/consent statement/proxy statement to the SunCoke Stockholders in connection with the solicitation of proxies to be voted at the SunCoke Special Meeting that SunCoke has called for the purposes described below. This joint prospectus/consent statement/proxy statement is first being mailed to SunCoke Stockholders on or about             , 2019 and provides SunCoke Stockholders with the information they need to know about the Merger and the Parent Stock Issuance Proposal to be able to vote or instruct their vote to be cast at the SunCoke Special Meeting.

Date, Time and Place

The SunCoke Special Meeting will be held on             , 2019 at                     , local time, at [the Hotel Arista, 2139 CityGate Lane, Naperville, Illinois 60563]. At the SunCoke Special Meeting, SunCoke Stockholders will be asked to consider and vote on the proposal described immediately below.

The Parent Stock Issuance Proposal

The Parent Stock Issuance Proposal is a proposal to approve the issuance of SunCoke Common Stock pursuant to the terms of the Merger Agreement in connection with the Merger.

If the Merger is completed, each SXCP Public Unit outstanding immediately prior to the effective time of the Merger will be converted into the right to receive (x) 1.40 shares of validly issued, fully paid and nonassessable SunCoke Common Stock and (y) a fraction of a share of SunCoke Common Stock equal to the product of (aa) the number of days beginning with the first day of the most recent full calendar quarter with respect to which an SXCP unitholder distribution record date has not occurred (or, if there is no such full calendar quarter, then beginning with the first day of the partial calendar quarter in which the Closing occurs), and ending on the day immediately prior to the Closing, multiplied by (bb) a daily distribution rate that is equal to the quotient of the most recent regular quarterly cash distribution paid by SXCP divided by 90, such product divided by $10.91, which was the closing price of the SunCoke Common Stock as of February 1, 2019, the last full trading day prior to the date of the execution of the Merger Agreement. Upon such conversion, each SXCP Public Unit will be canceled and will cease to exist.

Under NYSE rules, stockholder approval is required prior to the issuance of SunCoke Common Stock if the number of shares of common stock to be issued equals 20% or more of the number of shares of common stock outstanding prior to the issuance. The Parent Stock Issuance is expected to result in the issuance of a number of shares of SunCoke Common Stock equal to approximately [    ]% of the shares of SunCoke Common Stock outstanding immediately prior to the effective time of the Merger. Accordingly, SunCoke Stockholders are being asked to consider and vote upon the Parent Stock Issuance. The approval of the Parent Stock Issuance requires the affirmative vote (in person or by proxy) of the holders of a majority of the aggregate voting power present at the SunCoke Special Meeting or any adjournment or postponement thereof, provided a quorum is present.

Board Recommendation

The SunCoke Board recommends that SunCoke Stockholders vote “FOR” the Parent Stock Issuance Proposal. See the section titled “The Merger—Recommendation of the SunCoke Board and Its Reasons for the Merger.”

In considering the recommendation of the SunCoke Board with respect to the Parent Stock Issuance Proposal, you should be aware that SunCoke’s executive officers and directors may have interests that are different from, or in addition to, the interests of SunCoke Stockholders more generally. See the section titled “The Merger—Interests of Certain Persons in the Merger Transactions.”

27

Record Date; Outstanding Shares; Shares Entitled to Vote

Only SunCoke Stockholders of record as of the close of business on the SunCoke Vote Record Date of             , 2019, will be entitled to receive notice of and to vote at the SunCoke Special Meeting or at any adjournment or postponement thereof. SunCoke Common Stock held by SunCoke as treasury shares will not be entitled to vote.

As of the close of business on the SunCoke Vote Record Date, there were                    shares of SunCoke Common Stock and no other shares of capital stock outstanding and entitled to vote at the SunCoke Special Meeting. Each SunCoke Stockholder is entitled to one vote for each share of SunCoke Common Stock owned as of the SunCoke Vote Record Date.

A complete list of SunCoke Stockholders entitled to vote at the SunCoke Special Meeting will be available for inspection at SunCoke’s principal place of business during regular business hours for a period of no fewer than ten days before the SunCoke Special Meeting and, during the SunCoke Special Meeting, at [the Hotel Arista, 2139 CityGate Lane, Naperville, Illinois 60563].

Quorum

A majority of the outstanding shares of SunCoke Common Stock as of the SunCoke Vote Record Date must be represented in person or by proxy at the SunCoke Special Meeting in order to constitute a quorum.

Required Vote

The approval of the Parent Stock Issuance Proposal requires the affirmative vote (in person or by proxy) of the holders of a majority of the aggregate voting power present at the SunCoke Special Meeting or any adjournment or postponement thereof, provided a quorum is present. If you abstain from voting on the Parent Stock Issuance Proposal, your shares of SunCoke Common Stock will be counted as present for purposes of establishing a quorum, but the abstention will not be counted as a vote cast either “FOR” or “AGAINST” the Parent Stock Issuance Proposal.

The obligations of the parties to complete the Merger are conditioned upon the Parent Stock Issuance Approval. Accordingly, a vote against or an abstention with respect to the Parent Stock Issuance Proposal, or a failure to vote on the Parent Stock Issuance Proposal, to the extent such failure prevents the establishment of a quorum, will have the same effect as a vote against the Parent Stock Issuance Proposal and the Merger (although no vote for or against the Merger is taking place).

Stock Ownership of and Voting of SunCoke’s Directors and Executive Officers

As of the SunCoke Vote Record Date, SunCoke’s directors and executive officers beneficially owned and were entitled to vote, in the aggregate, approximately     % of the outstanding SunCoke Common Stock.

Voting and Submitting a Proxy for SunCoke Common Stock Held by Holders of Record

If you were a holder of record of SunCoke Common Stock at the close of business on the SunCoke Vote Record Date, you may vote in person by attending the SunCoke Special Meeting or, to ensure that your shares are represented at the SunCoke Special Meeting, you may authorize a proxy to vote:

28

When you submit a proxy by telephone or via the Internet, your proxy is recorded immediately. We encourage you to submit your proxy using these methods whenever possible. If you submit a proxy by telephone or via the Internet, please do not return your proxy card by mail.

All shares of SunCoke Common Stock represented by each properly executed and valid proxy received before the SunCoke Special Meeting will be voted in accordance with the instructions given on the proxy. If a SunCoke Stockholder executes a proxy card without giving instructions, the SunCoke Common Stock represented by that proxy card will be voted “FOR” the Parent Stock Issuance Proposal.

Your vote is important. Accordingly, please submit your proxy by telephone, via the Internet, or by mail whether or not you plan to attend the meeting in person. Proxies must be received by                    , Central Time, on            , 2019.

Voting and Submitting a Proxy for SunCoke Common Stock Held in Street Name

If your SunCoke Common Stock is held in an account at a bank, broker or other nominee, you must instruct the bank, broker or other nominee on how to vote them by following the instructions that the bank, broker or other nominee provides to you with these proxy materials. Most banks, brokers and other nominees offer the ability for stockholders to submit voting instructions by mail by completing a voting instruction card, by telephone and via the Internet.

If you hold your SunCoke Common Stock in a brokerage account and you do not provide voting instructions to your broker, your shares will not be voted on any proposal because under the current rules of the NYSE, brokers do not have discretionary authority to vote on the Parent Stock Issuance Proposal. Since there are no items on the agenda that your broker has discretionary authority to vote upon, broker non-votes will not be counted as present at the meeting if you fail to instruct your brokerage firm on how to vote on the Parent Stock Issuance Proposal. Therefore, a broker non-vote will have no effect on the Parent Stock Issuance Proposal, except to the extent such broker non-vote prevents the establishment of a quorum at the SunCoke Special Meeting.

If you hold shares through a bank, broker or other nominee and wish to vote your shares in person at the SunCoke Special Meeting, you must obtain a legal proxy from your bank, broker or other nominee and present it to the inspector of election with your ballot when you vote at the SunCoke Special Meeting.

Revocability of Proxies; Changing Your Vote

If you are a stockholder of record, you may revoke your proxy and/or change your vote by:

If you choose to revoke your proxy by written notice or submit a later-dated proxy, you must do so by                     , Central Time, on            , 2019.

If your shares are held in “street name,” please contact your broker, financial institution or other nominee and comply with the broker’s, financial institution’s or other nominee’s procedures if you want to change or revoke your previous voting instructions. Attending the SunCoke Special Meeting in person will not in and of itself revoke a previously submitted proxy unless you specifically request it.

29

Solicitation of Proxies

The cost of soliciting proxies will be borne by SunCoke. In addition to solicitation by mail, SunCoke’s officers and other employees may solicit proxies personally, by telephone, by e-mail and by facsimile. SunCoke may request banks and brokers or other similar agents or fiduciaries to transmit the proxy materials to the beneficial owners for their voting instructions and will reimburse them for their expenses in so doing. SunCoke has retained Morrow Sodali LLC (“Morrow Sodali”), 470 West Ave, Stamford, Connecticut 06902, to assist in the solicitation of proxies for an estimated fee of $18,500, plus reimbursement of certain out-of-pocket expenses.

No Other Business

No business shall be conducted at the SunCoke Special Meeting other than the matters described herein.

Adjournments

Adjournments may be made for the purpose of, among other things, soliciting additional proxies. If there are insufficient votes at the SunCoke Special Meeting to approve the Parent Stock Issuance Proposal and it is necessary or appropriate to solicit additional proxies, the SunCoke Special Meeting may be adjourned. The Chairman of the SunCoke Board or the President of SunCoke may adjourn the meeting whether or not a quorum is not present. SunCoke is not required to notify the SunCoke Stockholders of any adjournment of 30 days or less if the time and place of the adjourned meeting are announced at the SunCoke Special Meeting. At any adjourned meeting, SunCoke may transact any business that it might have transacted at the original meeting, provided that a quorum is present at such adjourned meeting. Proxies submitted by the SunCoke Stockholders for use at the SunCoke Special Meeting will be used at any adjournment or postponement of the SunCoke Special Meeting. References to the SunCoke Special Meeting in this joint prospectus/consent statement/proxy statement are to such SunCoke Special Meeting as may be adjourned or postponed.

Attending the SunCoke Special Meeting

All SunCoke Stockholders as of the close of business on the SunCoke Vote Record Date, or their duly appointed proxies, may attend the SunCoke Special Meeting. Seating, however, is limited. Admission to the SunCoke Special Meeting will be on a first-come, first-served basis. Registration will begin on the date of the SunCoke Special Meeting at                    local time, and seating will begin at                     local time.

THE MERGER

General

On February 4, 2019, SunCoke, Merger Sub, SXCP and SXCP General Partner entered into the Merger Agreement pursuant to which Merger Sub will be merged with and into SXCP, with SXCP being the surviving entity. In addition, if the Merger is successfully completed, SXCP Common Units will no longer be listed and traded on the NYSE.    

Pursuant to the Merger Agreement, all SXCP Public Units outstanding immediately prior to the effective time of the Merger will be converted into the right to receive the Merger Consideration and, upon such conversion, will be canceled and will cease to exist.    

The approval and adoption of the Merger Agreement and the Merger by SXCP requires the affirmative vote or consent of holders of at least a majority of the outstanding SXCP Common Units. Pursuant to the terms of a Support Agreement, dated as of February 4, 2019, by and between Sun Coal & Coke LLC (“SC&C”) and SXCP (such agreement, the “Support Agreement”), SC&C, a wholly owned subsidiary of SunCoke which as of February 4, 2019, beneficially owned 28,499,899 SXCP Common Units representing approximately 61.7% of the outstanding SXCP Common Units, has agreed to deliver a written consent approving (in all manners and by each applicable class) the Merger, the Merger Agreement and any other matters necessary for consummation of the Merger and the other transactions contemplated in the Merger Agreement (the “SC&C Written Consent”), within two business days after the effectiveness of the registration statement of which this joint prospectus/consent statement/proxy statement forms a part. The delivery of the SC&C Written Consent by SC&C will be sufficient to approve the Merger Agreement and the transactions contemplated thereby, including the Merger, on behalf of SXCP.

As a condition to the Closing, the SunCoke Stockholders must approve the Parent Stock Issuance at the SunCoke Special Meeting. The approval of the Parent Stock Issuance requires the affirmative vote (in person or by proxy) of the holders of a majority of the aggregate voting power present at the SunCoke Special Meeting or any adjournment or postponement thereof, provided a quorum is present.

SunCoke’s Ownership Interest in and Control of SXCP

SXCP Public Unitholders should be aware that SXCP is controlled by SunCoke through SunCoke’s 100% ownership of the SXCP General Partner. The SXCP General Partner owns all of the outstanding general partner interests in SXCP. As a result, SunCoke appoints the members of the SXCP Board, a majority of whom are affiliated with SunCoke and its affiliates, and thereby could be seen as controlling all of SXCP’s decisions, other than those involving certain conflicts of interest with SunCoke or that require an affirmative vote of holders of the limited partner interests in SXCP pursuant to and in the percentages specified by the SXCP Partnership Agreement. Additionally, in July 2015, the SXCP Board authorized a program for SXCP to repurchase up to $50 million of the SXCP Common Units from time to time in open market transactions, including block trades, or in privately negotiated transactions. As of February 4, 2019, $12.8 million of SXCP Common Units had been repurchased and canceled under the authorized unit repurchase program. As of February 4, 2019, SunCoke, through its ownership of SC&C, owned approximately 61.7% of the outstanding SXCP Common Units.

Certain persons associated with SXCP General Partner and SXCP have a relationship with SunCoke.

Michael G. Rippey, who serves as Chairman, President and Chief Executive Officer of SXCP General Partner, also serves as a director and executive officer of SunCoke. Fay West, who serves as a director and the Senior Vice President and Chief Financial Officer of SXCP General Partner, also serves as an executive officer of SunCoke. P. Michael Hardesty, who serves as a director and the Senior Vice President, Commercial Operations, Business Development, Terminals and International Coke of SXCP General Partner, also serves as

31

an executive officer of SunCoke. Katherine Gates, who serves as a director and Senior Vice President, General Counsel and Chief Compliance Officer of SXCP General Partner, also serves as an executive officer of SunCoke. Gary Yeaw, who serves as Senior Vice President, Human Resources of SXCP General Partner, also serves as an executive officer at SunCoke.

See the section titled “The Merger—Interests of Certain Persons in the Merger Transactions.”

Background of the Merger

On October 31, 2016, SunCoke announced that it had submitted a proposal to the SXCP Board to acquire all of the SXCP Common Units not already owned by SunCoke and its affiliates. Under the terms of the proposal, SXCP Public Unitholders would receive approximately 1.65 new shares of SunCoke Common Stock for each SXCP Public Unit, representing an implied purchase price of $17.80 per SXCP Common Unit, or approximately a 5% premium, based on the closing price of SXCP Common Units on October 28, 2016, the last trading day prior to announcement of the proposal. At the time of the announcement, SunCoke owned approximately 53.9% of SXCP’s outstanding Common Units, which it stated that it intended to vote in favor of the proposed transaction. SunCoke also stated at the time that it expected that the proposal would be delegated to the SXCP Conflicts Committee for its consideration.

Following its receipt of the proposal, the SXCP Conflicts Committee engaged legal and financial advisors to assist it in considering the proposal.

On April 20, 2017, in connection with the announcement of its first quarter 2017 results, SunCoke announced the termination of discussions with the SXCP Conflicts Committee. SunCoke disclosed that the SXCP Conflicts Committee and its independent advisors reviewed the proposal made by SunCoke and had discussions with SunCoke since receiving the proposal, and that the parties determined that they would not be able to reach an agreement and therefore terminated discussions regarding the proposed transaction. At the time, the then-Chairman, President and Chief Executive Officer of SunCoke stated, “While we continue to believe strongly in the merits of a simplified structure, we were focused on taking a disciplined approach and ultimately it became clear we would not reach an agreement with the [SXCP] Conflicts Committee on a value, through the exchange ratio, for the unaffiliated LP units.”

On February 5, 2018, at a meeting of the SunCoke Board, Michael G. Rippey, who had been elected as SunCoke’s Chief Executive Officer and President effective December 1, 2017, discussed the potential future advisability of SunCoke making a simplification proposal to SXCP. Following this discussion, it was the consensus of the SunCoke Board that the matter should be reviewed in greater depth at a subsequent SunCoke Board meeting.

On July 20, 2018, at a meeting of the SunCoke Board, Mr. Rippey and members of management discussed whether SunCoke should consider making a potential future simplification proposal to SXCP. Following this discussion, it was the consensus of the SunCoke Board that the matter should be reviewed in greater depth at a subsequent SunCoke Board meeting. The SunCoke Board did not specify when the matter should be revisited.

On November 5, 2018, the SunCoke Board held a special telephonic meeting to discuss the potential simplification of SunCoke’s structure by SunCoke’s acquisition of all of the SXCP Common Units not already owned by SunCoke and its affiliates. Prior to the meeting, SunCoke engaged Evercore and lawyers from Baker Botts L.L.P. (“Baker Botts”), as SunCoke’s financial and legal advisors, respectively, each of whom had assisted SunCoke on the simplification proposal from October 2016 to April 2017. At the meeting, SunCoke management discussed, among other things, the rationale for simplifying SunCoke’s structure, including potential strategic benefits, proposed transaction structure, certain legal and tax considerations, and indicative timing. At the end of the meeting, Mr. Rippey indicated that SunCoke management was prepared, subject to the SunCoke Board’s approval, to provide a merger proposal to SXCP promptly following the upcoming SunCoke Board meeting

32

scheduled for November 27, 2018. Later that day, Mr. Rippey contacted John W. Somerhalder II, chairman of the SXCP Conflicts Committee, to inform him of the potential forthcoming simplification proposal from SunCoke.

On November 26, 2018, Mr. Somerhalder, on behalf of the SXCP Conflicts Committee, contacted representatives of Akin Gump Strauss Hauer & Feld LLP (“Akin Gump”) to engage Akin Gump as independent legal counsel to represent the SXCP Conflicts Committee in connection with the potential transaction. An engagement letter dated November 27, 2018, detailing the terms of Akin Gump’s engagement as independent legal advisor to the SXCP Conflicts Committee, was subsequently executed. Also on November 26, 2018, on the instructions of the SXCP Conflicts Committee, representatives of Akin Gump contacted three financial advisors, including Citigroup Global Markets Inc. (“Citi”), to discuss the SXCP Conflicts Committee’s interest in interviewing them to serve as financial advisor to the SXCP Conflicts Committee in connection with the potential transaction.

On November 27, 2018, the SunCoke Board convened a special telephonic meeting, attended by six of the seven SunCoke directors, as well as members of SunCoke management and representatives of Evercore and Baker Botts. Evercore discussed with the SunCoke Board certain financial and market considerations in the context of the potential simplification transaction. Among other things, the SunCoke Board also discussed with SunCoke management, Evercore and Baker Botts the rationale, potential synergies and other benefits for a simplification transaction in the form of an all-equity stock-for-unit exchange, whereby SunCoke would acquire all outstanding SXCP Common Units not already owned by SunCoke and its affiliates, and the potential implications of attempting and failing to consummate a simplification transaction as was the case two years earlier. After discussion, the SunCoke Board directed SunCoke management to make a proposal to the SXCP Board on the terms approved by the SunCoke Board and further directed SunCoke management to negotiate the terms of such proposal with the SXCP Conflicts Committee and its advisors to determine whether a mutually acceptable agreement could be reached. Later that day, Mr. Rippey notified Mr. Somerhalder that a letter outlining SunCoke’s proposal would be forthcoming.

On November 28, 2018, Mr. Rippey, on behalf of SunCoke, delivered SunCoke’s proposal letter and draft form of merger agreement to the SXCP Board, proposing that SunCoke acquire all outstanding SXCP Common Units not already owned by SunCoke and its affiliates through a merger involving SXCP and a wholly owned subsidiary of SunCoke. The proposal contemplated an all-equity stock-for-unit exchange at an exchange ratio of 1.35 new shares of SunCoke Common Stock for each outstanding publicly held SXCP Common Unit. The draft form of Merger Agreement contemplated, among other things, that the SunCoke Board could withdraw, modify or qualify its recommendation that the SunCoke Stockholders approve the proposed Parent Stock Issuance in connection with the proposed transaction if the SunCoke Board determined in good faith (after consultation with SunCoke’s financial advisors and outside legal counsel) that the failure to take such action would be reasonably likely to be inconsistent with its fiduciary duties to stockholders under applicable law, terminate the Merger Agreement thereafter, and pay the direct and indirect expenses and costs incurred by or on behalf of SXCP, without a termination fee.

On November 29, 2018, the SXCP Conflicts Committee held a meeting, with representatives of Akin Gump in attendance. At that meeting, the SXCP Conflicts Committee interviewed a potential financial advisor to assist the SXCP Conflicts Committee in connection with the proposed Merger.

On December 3, 2018, at a regularly scheduled telephonic meeting, the SXCP Board adopted resolutions formally delegating authority to the SXCP Conflicts Committee, consisting of Mr. Somerhalder and Martha Z. Carnes, independent members of the SXCP Board, to review, evaluate and negotiate the terms of the potential simplification transaction and related agreements and arrangements with SunCoke, for the purpose of providing, if appropriate, “Special Approval” pursuant to Section 7.9(c) of the SXCP Partnership Agreement and to evaluate the terms and conditions, and determine the advisability, of such a transaction.

Also on December 3, 2018, the SXCP Conflicts Committee met again to interview Citi and one additional potential financial advisor. Representatives of Akin Gump also were present at the meeting. Following the

33

interviews, the SXCP Conflicts Committee resolved to engage Citi as its financial advisor, subject to negotiation of mutually acceptable terms. The SXCP Conflicts Committee selected Citi based on, among other things, Citi’s experience, reputation with similar transactions, and familiarity with SunCoke and SXCP and their industries. The SXCP Conflicts Committee also considered certain information provided by Citi regarding Citi’s material investment banking relationships with SunCoke and SXCP during the prior two-year period.

On December 10, 2018, members of SunCoke management, along with representatives of Evercore and Baker Botts, held a half-day meeting near SunCoke’s headquarters office at which SunCoke management delivered a presentation, with the members of the SXCP Conflicts Committee and representatives of Akin Gump and Citi attending in person and telephonically. The management presentation described SunCoke’s rationale for pursuing the Merger, provided an overview of the proposed transaction, and included certain financial projections prepared by SunCoke management and an overview of the potential pro forma financial impact of the proposed transaction.

On December 11, 2018, SunCoke provided the SXCP Conflicts Committee and its legal and financial advisors with access to a virtual data room containing legal and financial due diligence materials related to SunCoke and SXCP, including financial projections with respect to SunCoke and SXCP.

On December 13, 2018, the SXCP Conflicts Committee held a telephonic meeting attended by representatives of Akin Gump and Citi. At the meeting, Citi provided the SXCP Conflicts Committee with an overview of master limited partnership (“MLP”) market trends, and Akin Gump reviewed with the members of the SXCP Conflicts Committee their duties and obligations under the SXCP Partnership Agreement in connection with their evaluation and consideration of the proposed merger.

On December 20, 2018, the SXCP Conflicts Committee held a telephonic meeting, also attended by representatives of Akin Gump and Citi. At the meeting, Citi provided the SXCP Conflicts Committee with a preliminary overview of the financial terms of the proposed transaction and certain related matters, and the SXCP Conflicts Committee and its advisors further discussed the proposed transaction. The SXCP Conflicts Committee members decided to defer consideration of any potential counterproposal until after receipt of certain additional financial and other information from SunCoke, including as to the assumptions underlying SunCoke’s financial projections.

On December 26, 2018, the SXCP Conflicts Committee held a telephonic meeting, also attended by representatives of Akin Gump and Citi. During the meeting, the SXCP Conflicts Committee and its advisors discussed the supplemental financial information provided on behalf of SunCoke and further discussed preliminary financial aspects of the proposed transaction.

On December 28, 2018, the SXCP Conflicts Committee held a telephonic meeting, also attended by representatives of Akin Gump and Citi, to further discuss certain terms and preliminary financial aspects of the proposed transaction. At the end of the meeting, the SXCP Conflicts Committee instructed its advisors to provide a counterproposal to SunCoke, contemplating: (i) an exchange ratio of 1.45 new shares of SunCoke Common Stock per SXCP Common Unit; and (ii) a one-time, special cash distribution of $1.60 for each outstanding publicly-held SXCP Common Unit at closing. On December 29, 2018, at the direction of the SXCP Conflicts Committee, representatives of Citi delivered to representatives of Evercore the SXCP Conflicts Committee’s response to SunCoke’s proposal of November 28, 2018, reflecting the above terms. The SXCP Conflicts Committee’s counterproposal also noted that the SXCP Conflicts Committee was continuing to evaluate whether to require that the Merger be conditioned upon the approval of a majority of the SXCP Public Unitholders, in addition to the other approvals set forth in the SunCoke proposal.

On January 2, 2019, following discussions with representatives of Evercore and Baker Botts, SunCoke responded to the SXCP Conflicts Committee’s counterproposal of December 29, 2018 by delivering a revised proposal to the SXCP Conflicts Committee contemplating an exchange ratio of 1.39 new shares of SunCoke

34

Common Stock per SXCP Common Unit, without a one-time special cash distribution. In addition, SunCoke noted in its revised proposal that it was not receptive to requiring a vote of the SXCP Public Unitholders.

On January 4, 2019, the SXCP Conflicts Committee held a telephonic meeting to discuss SunCoke’s revised proposal with representatives of Akin Gump and Citi. After considering and discussing SunCoke’s revised proposal, the SXCP Conflicts Committee decided to respond to SunCoke’s January 2, 2019 letter by proposing (i) an exchange ratio of 1.42 new shares of SunCoke Common Stock per SXCP Common Unit; and (ii) a one-time, special cash distribution of $1.20 for each outstanding publicly-held SXCP Common Unit at closing. During the meeting, the SXCP Conflicts Committee and Akin Gump also discussed the initial draft of the Merger Agreement that SunCoke had provided and proposed revisions to such draft.

Later on January 4, 2019, at the direction of the SXCP Conflicts Committee, representatives of Citi delivered to representatives of Evercore the SXCP Conflicts Committee’s response, reflecting the terms discussed at the SXCP Conflicts Committee’s January 4, 2019 meeting, to SunCoke’s January 2, 2019 proposal. In addition, as it had indicated in its December 29, 2018 response, the SXCP Conflicts Committee noted that it was continuing to evaluate whether to require that the Merger be conditioned upon the approval of a majority of the SXCP Public Unitholders, in addition to the other approvals set forth in SunCoke’s November 28, 2018 proposal.

On January 8, 2019, representatives of Akin Gump, on behalf of the SXCP Conflicts Committee, sent to Baker Botts comments to the draft form of Merger Agreement that had been delivered with SunCoke’s proposal of November 28, 2018. Among the comments proposed by Akin Gump were (i) revisions meant to enhance the likelihood of consummation of the Merger, including the payment of a $6 million termination fee from SunCoke to SXCP if the Merger Agreement was terminated under certain circumstances, and (ii) covenants restricting SunCoke’s ability to undertake certain equity issuances and third-party agreements in the period between signing and closing. The proposed revisions to the draft Merger Agreement did not include a vote of a majority of the SXCP Public Unitholders.

On January 11, 2019, SunCoke responded to the SXCP Conflicts Committee’s January 6, 2019 counterproposal by delivering a further revised proposal contemplating an exchange ratio of 1.39 new shares of SunCoke Common Stock per SXCP Common Unit. In its revised proposal, SunCoke expressed its view that paying a one-time, special cash distribution would be contrary to a critical objective of the proposed merger, which was to strengthen the balance sheet of the resultant combined entity. However, SunCoke proposed implementing, subject to approval of the SunCoke Board, a quarterly dividend of $0.05 per share of SunCoke Common Stock, or $0.20 per share of SunCoke Common Stock on an annualized basis, beginning with the first full quarterly period after the closing of the Merger, which represented an increase from the proposed quarterly dividend of $0.01 per share of SunCoke Common Stock, or $0.04 per share of SunCoke Common Stock on an annualized basis, included in the financial projections that had been provided by SunCoke to the SXCP Conflicts Committee.

On January 12, 2019, the SXCP Conflicts Committee held a telephonic meeting with representatives of Akin Gump and Citi. After considering and discussing SunCoke’s January 11, 2019 proposal, the SXCP Conflicts Committee decided to respond to SunCoke’s January 11, 2019 letter by proposing: (i) an exchange ratio of 1.39 new shares of SunCoke Common Stock per SXCP Common Unit; and (ii) a one-time, special cash distribution of $0.50 for each outstanding publicly-held SXCP Common Unit at closing.

On January 13, 2019, at the direction of the SXCP Conflicts Committee, representatives of Citi delivered to representatives of Evercore the SXCP Conflicts Committee’s response, reflecting the terms discussed at the SXCP Conflicts Committee’s January 12, 2019 meeting, to SunCoke’s January 11, 2019 proposal.

On January 15, 2019, SunCoke responded to SXCP’s January 13, 2019 counterproposal by delivering a further revised proposal to the SXCP Conflicts Committee, contemplating an exchange ratio of 1.39 new shares

35

of SunCoke Common Stock per SXCP Common Unit. In its revised proposal, SunCoke proposed implementing, subject to approval of the SunCoke Board, a quarterly dividend of $0.06 per share of SunCoke Common Stock, or $0.24 per share of SunCoke Common Stock on an annualized basis, beginning with the first full quarterly period after the closing of the Merger.

On January 16, 2019, the SXCP Conflicts Committee held a telephonic meeting to discuss the revised SunCoke proposal with representatives of Akin Gump and Citi. After considering and discussing SunCoke’s revised proposal, the SXCP Conflicts Committee determined it would further consider the terms of the proposed merger before determining whether and the terms on which to deliver a counterproposal to SunCoke. Also at the meeting, the SXCP Conflicts Committee and its advisors discussed updated financial forecasts for SunCoke and SXCP that had been provided on that date, on behalf of SunCoke primarily to reflect SunCoke’s and SXCP’s actual full-year 2018 results and year-end financial position.

On January 17, 2019, the SunCoke Board convened a special telephonic meeting, attended by all seven directors, as well as members of SunCoke management. During this meeting, members of management provided an update on the status of negotiations with the SXCP Conflicts Committee and the most recent counterproposal from the SXCP Conflicts Committee.

On January 18, 2019, Mr. Rippey called Mr. Somerhalder to discuss the SXCP Conflicts Committee’s continued request for a one-time special cash payment as part of the proposed merger consideration and SunCoke’s continued rejection of this request.

On January 19, 2019, the SXCP Conflicts Committee held a telephonic meeting, attended by representatives of Akin Gump and Citi. During the meeting, the SXCP Conflicts Committee and its advisors discussed a potential response to SunCoke’s revised proposal. After the Committee temporarily adjourned the meeting, Mr. Somerhalder called Mr. Rippey to further discuss SunCoke’s revised proposal.

Later on January 19, 2019, the SXCP Conflicts Committee reconvened the telephonic meeting with representatives of Akin Gump and Citi in attendance. Mr. Somerhalder updated the participants on his conversation with Mr. Rippey, and the SXCP Conflicts Committee and its advisors further discussed the terms of SunCoke’s revised proposal. Following this discussion, the SXCP Conflicts Committee determined to respond to SunCoke by proposing: (i) an exchange ratio of 1.40 new shares of SunCoke Common Stock per SXCP Common Unit; and (ii) an assumption that: (w) SunCoke would implement a quarterly dividend of at least $0.06 per share of SunCoke Common Stock, or $0.24 per share of SunCoke Common Stock on an annualized basis, following closing of the Merger; (x) SXCP would continue to declare and pay quarterly cash distributions of at least $0.40 per unit for each fiscal quarter prior to closing of the Merger; (y) the Merger would not close prior to the record date for the distribution relating to the first quarter of 2019; and (z) the SXCP Public Unitholders would receive a final distribution at closing equal to the product of (1) the number of days elapsed from the first day of the most recent fiscal quarter with respect to which a distribution record date has not occurred multiplied by (2) a daily distribution rate equal to the quotient of the most recent regular quarterly cash distribution paid by SXCP divided by 90. On January 20, 2019, at the direction of the SXCP Conflicts Committee, representatives of Citi delivered to representatives of Evercore the SXCP Conflicts Committee’s response, reflecting the terms discussed at the SXCP Conflicts Committee’s January 19, 2019 meeting, to SunCoke’s January 15, 2019 proposal.

On January 22, 2019, SunCoke responded to SXCP’s January 21, 2019 counterproposal by delivering a further revised proposal to the SXCP Conflicts Committee proposing to: (a) cause the exchange of 1.40 new shares of SunCoke Common Stock for each outstanding publicly-held SXCP Common Unit; (b) announce its intention to implement a quarterly dividend, subject to the approval of its Board of Directors, of $0.06 per share of SunCoke Common Stock, or $0.24 per share of SunCoke Common Stock on an annualized basis, with respect to the first full calendar quarter after the closing of the Merger and payable in the quarter thereafter; (c) cause SXCP to continue to declare and pay quarterly cash distributions of $0.40 per SXCP Common Unit for each fiscal quarter with respect to which the record date occurs prior to closing of the Merger; and (d) cause the SXCP

36

Public Unitholders to receive a final distribution at closing, payable in shares of SunCoke Common Stock (valued as of the date prior to execution of the Merger Agreement) equal to the product of: (i) the number of days elapsed from the first day of the most recent fiscal quarter with respect to which a distribution record date has not occurred multiplied by (ii) a daily distribution rate equal to the quotient of the most recent regular quarterly cash distribution paid by SXCP divided by 90. In making this revised proposal, SunCoke assumed that the Merger would not close prior to the record date for the distribution relating to the first quarter of 2019. This revised proposal, signifying the mutual intent of SunCoke and the SXCP Conflicts Committee, subject to the negotiation, execution and delivery of mutually satisfactory definitive agreements with respect to the Merger, was countersigned by Mr. Somerhalder on behalf of the SXCP Conflicts Committee and delivered to SunCoke on January 29, 2019.

Also on January 22, 2019, on behalf of SunCoke, Baker Botts sent to Akin Gump a revised draft of the Merger Agreement in response to the comments that Akin Gump had sent on January 8, 2019. In the revised draft, SunCoke agreed to certain post-signing restrictions on SunCoke, including limitations on issuance of additional SunCoke equity prior to closing, but rejected the proposal of a termination fee in the event that SunCoke terminated the Merger Agreement following a change of recommendation by the SunCoke Board.

On January 24, 2019, the SXCP Conflicts Committee held a telephonic meeting with representatives of Akin Gump and Citi in attendance. During the meeting, the SXCP Conflicts Committee discussed SunCoke’s January 22, 2019 proposal and the revised draft of the Merger Agreement received from Baker Botts.

On January 25, 2019, on behalf of the SXCP Conflicts Committee, Akin Gump sent to Baker Botts a revised draft of the Merger Agreement, in response to the comments that Baker Botts had sent on January 22, 2019. The revised draft contemplated that, during the period between signing and closing, SunCoke would not be permitted to issue additional equity valued at more than $100 million, and also contemplated a termination fee of $6 million in the event that SunCoke terminated the Merger Agreement following a change of recommendation by the SunCoke Board. Later that afternoon, representatives of Baker Botts, Akin Gump and SunCoke management conferred by telephone regarding the remaining open points in the draft Merger Agreement. During the call, the representatives of SunCoke proposed to agree to: (i) the SXCP Conflicts Committee’s request for a $6 million termination fee in the event that SunCoke terminated the Merger Agreement following a change of recommendation by the SunCoke Board; and (ii) the SXCP Conflicts Committee’s request for a lower limit on equity issuances by SunCoke, if the SXCP Conflicts Committee otherwise agreed to the then-current draft.

On January 26, 2019, the SXCP Conflicts Committee held a telephonic meeting, also attended by representatives of Akin Gump and Citi. Representatives of Akin Gump informed the SXCP Conflicts Committee regarding Akin Gump’s conversation with SunCoke and Baker Botts representatives on the revised draft Merger Agreement.

Later that day, representatives of Akin Gump reported to Baker Botts that the SXCP Conflicts Committee had accepted SunCoke’s revisions to the Merger Agreement as outlined by SunCoke on January 25, 2019, subject to review of the revised draft Merger Agreement reflecting such revisions.

On January 28, 2019, on behalf of SunCoke, Baker Botts sent to Akin Gump a revised draft of the Merger Agreement, reflecting the discussion of January 25, 2019. Also later that day, Baker Botts sent Akin Gump an initial draft of the Support Agreement.

Over the next several days, the parties spoke with frequency regarding open items, including whether separate disclosure schedules were necessary to the Merger Agreement, additional edits to the Merger Agreement, including regarding the formula for SXCP distributions through closing, the Support Agreement and the public disclosure for the announcement of the execution of the Merger Agreement. The parties ultimately determined that no separate disclosure letters were required and instead included the necessary disclosures as schedules to the Merger Agreement.

37

On February 4, 2019, the SXCP Conflicts Committee held a telephonic meeting, which was attended by representatives of Akin Gump and Citi. During the meeting, Akin Gump reviewed with the SXCP Conflicts Committee the final terms of the Merger Agreement and Support Agreement. Also at this meeting, Citi reviewed with the SXCP Conflicts Committee its financial analysis of the Exchange Ratio and rendered an oral opinion, confirmed by delivery of a written opinion dated February 4, 2019, to the SXCP Conflicts Committee to the effect that, as of such date and based on and subject to various assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken, the Exchange Ratio provided for pursuant to the Merger Agreement was fair, from a financial point of view, to SXCP Public Unitholders. After discussion, the SXCP Conflicts Committee unanimously (i) determined that the Merger Agreement, the Support Agreement and the transactions contemplated thereby are not adverse to, and are in the best interest of, SXCP, including the SXCP Public Unitholders; (ii) approved the Merger Agreement, the Support Agreement and the transactions contemplated thereby, including the Merger, which approval constituted “Special Approval” under the SXCP Partnership Agreement; and (iii) recommended that the SXCP Board approve the Merger Agreement, the Support Agreement and the transactions contemplated thereby, including the Merger. See the section titled “The Merger—Recommendations of the SXCP Conflicts Committee and the SXCP Board and Their Reasons for the Merger.”

Later on February 4, 2019, a special telephonic meeting of the SXCP Board was held. In addition to members of SunCoke management, the meeting was attended by representatives of both Akin Gump and Baker Botts. At the meeting, the SXCP Conflicts Committee reported to the full SXCP Board as to its determinations and its receipt of Citi’s opinion as to the fairness, from a financial point of view, of the Exchange Ratio provided for pursuant to the Merger Agreement. The full SXCP Board discussed the proposed Merger with the SXCP Conflicts Committee. At this meeting, the SXCP Board (acting upon the recommendation of the SXCP Conflicts Committee) unanimously (i) determined that the Merger Agreement and the transactions contemplated thereby were in the best interest of SXCP; (ii) approved the Merger Agreement and the transactions contemplated thereby, including the Merger; and (iii) directed that the Merger Agreement be submitted to a vote of SXCP Common Unitholders and authorized the SXCP Common Unitholders to act by written consent pursuant to Section 13.11 of the SXCP Partnership Agreement.

Also on February 4, 2019, a special telephonic meeting of the SunCoke Board was convened, with members of SunCoke management and representatives of Evercore and Baker Botts also in attendance. At this meeting, at the request of the SunCoke Board, management reviewed the principal terms of the Merger Agreement. Additionally, Evercore reviewed its financial analysis of the Exchange Ratio and rendered an oral opinion, later confirmed by delivery of a written opinion dated February 4, 2019, to the SunCoke Board that, as of such date and based upon and subject to the factors, procedures, assumptions, qualifications and limitations set forth in its opinion, the Exchange Ratio was fair, from a financial point of view, to SunCoke. The SunCoke Board also discussed the potential market reaction to the transaction as well as perceived potential benefits of, and other considerations relating to, the Merger. After discussion, the SunCoke Board unanimously (i) determined that the Merger Agreement and the transactions contemplated thereby, including the Merger and the Parent Stock Issuance, were in the best interests of SunCoke and its stockholders, (ii) approved and declared advisable the Merger Agreement and the transactions contemplated thereby, including the Merger and the Parent Stock Issuance, and (iii) resolved to submit the Parent Stock Issuance to a vote of SunCoke’s stockholders and recommend approval of the Parent Stock Issuance at the SunCoke Special Meeting.

Resolution of Conflicts of Interest; Standards of Conduct and Modification of Duties

The approval of the Merger Agreement and the transactions contemplated thereby, including the Merger, by a majority of the members of the SXCP Conflicts Committee acting in good faith constituted “Special Approval” under the SXCP Partnership Agreement. Under Section 7.9(c) of the SXCP Partnership Agreement, whenever a potential conflict of interest exists, such as consideration of the Merger Agreement and the Merger and other transactions contemplated thereby, any resolution or course of action by the SXCP General Partner or its affiliates in respect of such conflict of interest will be permitted and conclusively deemed approved by SXCP and

38

by all of the partners of SXCP, and will not constitute a breach of the SXCP Partnership Agreement or of any duty existing at law, in equity or otherwise or obligation of any type, if the resolution or course of action is approved by Special Approval.

Under Section 7.10(b) of the SXCP Partnership Agreement, any action taken or omitted to be taken by the SXCP General Partner in reliance upon the advice or opinion of certain advisers (including legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisors selected by it), as to matters reasonably believed to be in such adviser’s professional or expert competence, will be “conclusively presumed to have been done or omitted in good faith and in accordance with such advice or opinion.”

Recommendations of the SXCP Conflicts Committee and the SXCP Board and Their Reasons for the Merger

The SXCP Conflicts Committee consists of two independent directors, John W. Somerhalder II and Martha Z. Carnes, each of whom was appointed on August 11, 2017, to serve as directors effective as of September 1, 2017, concurrently with the resignations of C. Scott Hobbs, Wayne L. Moore and Nancy M. Snyder. In resolutions approved by the SXCP Board on December 3, 2018, the SXCP Board authorized the SXCP Conflicts Committee to, among other things, (i) review and evaluate the terms and conditions, and determine the advisability, of the proposed Merger; (ii) negotiate, or delegate the ability to negotiate to any persons, with any party the SXCP Conflicts Committee deems appropriate, with respect to the terms and conditions of the proposed Merger; (iii) determine whether to give or withhold the SXCP Conflicts Committee’s approval of the proposed Merger, including by “Special Approval” pursuant to Section 7.9(c) of the SXCP Partnership Agreement; and (iv) make a recommendation to the SXCP Board whether to approve the proposed Merger.

The SXCP Conflicts Committee retained Akin Gump as its legal counsel and Citi as its financial advisor in connection with its evaluation of the proposed Merger. The SXCP Conflicts Committee, among other things, conducted a review and evaluation of SunCoke’s proposal and conducted negotiations with SunCoke and its representatives with respect to the Merger, the Merger Agreement and the Support Agreement.

On February 4, 2019, the SXCP Conflicts Committee unanimously (i) determined that the Merger Agreement and the transactions contemplated thereby are not adverse to, and are in the best interest of, SXCP, including the SXCP Public Unitholders; (ii) approved the Merger Agreement, the Support Agreement and the transactions contemplated thereby, including the Merger, which approval constituted “Special Approval” under the SXCP Partnership Agreement; and (iii) recommended that the SXCP Board approve the Merger Agreement, the Support Agreement and the transactions contemplated thereby, including the Merger.    

Later on February 4, 2019, the SXCP Board (acting upon the recommendation of the SXCP Conflicts Committee) (i) determined that the Merger Agreement and the transactions contemplated thereby are in the best interest of SXCP, (ii) approved the Merger Agreement and the transactions contemplated thereby, including the Merger, and (iii) directed that the Merger Agreement be submitted to a vote of SXCP Common Unitholders and authorized the SXCP Common Unitholders to act by written consent pursuant to Section 13.11 of the SXCP Partnership Agreement.

The SXCP General Partner, the SXCP Conflicts Committee and the SXCP Board have not, including, without limitation, in making the determinations and approvals set forth above, assumed any obligations to SXCP or its limited partners (whether fiduciary, contractual, implied or otherwise) other than those obligations that may exist pursuant to the SXCP Partnership Agreement. Under the SXCP Partnership Agreement, whenever the SXCP General Partner, the SXCP Board or any committee of the SXCP Board (including the SXCP Conflicts Committee) makes a determination or takes any other action in its capacity as the general partner of SXCP then, unless another express standard is provided for in the SXCP Partnership Agreement, the SXCP General Partner, SXCP General Partner, the SXCP Board or such committee must make such determination or take or decline to

39

take such other action in good faith and is not subject to any higher standard under the SXCP Partnership Agreement or under applicable law. A determination, other action or failure to act by SXCP General Partner, the SXCP Board or any committee thereof (including the SXCP Conflicts Committee) will be deemed to be in good faith unless the SXCP General Partner, the SXCP Board or any committee thereof (including the SXCP Conflicts Committee) believed such determination, other action or failure to act was adverse to the interests of SXCP. Nothing in this joint prospectus/consent statement/proxy statement or the actions or determinations of the SXCP General Partner, the SXCP Board or the SXCP Conflicts Committee described in this joint prospectus/consent statement/proxy statement should be read to mean that the SXCP General Partner, the SXCP Board or the SXCP Conflicts Committee assumed any obligations to SXCP or its limited partners (whether fiduciary, contractual, implied, or otherwise) other than those obligations that may exist pursuant to the SXCP Partnership Agreement. You are urged to read the full text of the SXCP Partnership Agreement, which is incorporated by reference into this joint prospectus/consent statement/proxy statement. See the section titled “Where You Can Find More Information.”

The SXCP Conflicts Committee consulted with its legal and financial advisors and considered various factors in making its determination and approvals with respect to the Merger, the Merger Agreement and the Support Agreement, and the related recommendation to the SXCP Board. The SXCP Conflicts Committee viewed the following factors as generally positive or favorable in arriving at its determination, approvals and recommendation:

41

The SXCP Conflicts Committee viewed the following factors as generally negative or unfavorable in arriving at its determination, approvals and recommendation:

43

The foregoing discussion of the information and factors considered by the SXCP Conflicts Committee is not intended to be exhaustive, but includes material factors the SXCP Conflicts Committee considered. In view of the variety of factors and the quality and amount of information considered, the SXCP Conflicts Committee as a whole did not find it practicable to and did not quantify or otherwise assign relative weights to the specific factors considered in reaching its determination but conducted an overall evaluation of the Merger. Individual members of the SXCP Conflicts Committee may have given different relative considerations to different factors. Overall, the SXCP Conflicts Committee believed that the positive factors supporting the Merger outweighed the negative factors it considered.

The explanation of the reasoning of the SXCP Conflicts Committee and certain information presented in this section are forward-looking in nature and, therefore, the information should be read in light of the factors discussed in the sections titled “Information Regarding Forward-Looking Statements” and “Risk Factors.”

In reaching its conclusions regarding the Merger, the SXCP Board not only considered the process by which the SXCP Conflicts Committee has made its recommendations but also considered the matters described above or considered by the SXCP Conflicts Committee. As in the case of the SXCP Conflicts Committee, in view of the variety of factors and the quality and amount of information considered, the SXCP Board as a whole did not find it practicable to and did not quantify or otherwise assign relative weights to the specific factors considered in reaching its determination but conducted an overall review of the Merger. Individual members of the SXCP Board may have given different relative considerations to different factors.

Unaudited Financial Projections of SunCoke and SXCP

Neither SunCoke nor SXCP routinely publishes projections as to long-term future performance, earnings or dividends and distributions. In connection with the proposed Merger, management of SunCoke prepared non-public projections relating to the future financial and operating performance of SunCoke and SXCP with respect to the fiscal years ending December 31, 2019 through 2023. The projections summarized below were provided to the SXCP Conflicts Committee, the SXCP Board and the SunCoke Board in connection with their analysis of the Merger. These financial projections also were provided to SunCoke’s financial advisor, Evercore, and to the SXCP Conflicts Committee’s financial advisor, Citi, for their use and reliance in connection with their respective analyses and opinions described under the headings “—Opinion of SunCoke’s Financial Advisor” and “—Opinion of the SXCP Conflicts Committee’s Financial Advisor,” respectively. The summary of these projections is included below because these projections were made available to the SXCP Conflicts Committee, the SXCP Board, the SunCoke Board and their respective financial advisors in connection with the proposed Merger.

You should be aware that uncertainties are inherent in prospective financial information of any kind, and such uncertainties may increase with the passage of time. None of SunCoke or SXCP or any of their affiliates, advisors, officers, directors, or representatives has made or makes any representation or can give any assurance to any SXCP Common Unitholder or SunCoke Stockholder, or any other person, regarding the ultimate performance of SXCP or SunCoke compared to the summarized information set forth below or that any such results will be achieved.

44

The inclusion of the following summary projections in this joint prospectus/consent statement/proxy statement should not be regarded as an indication that SXCP, SunCoke, or their respective advisors or other representatives considered or consider the projections to be necessarily predictive of actual future performance or events, and the summary projections set forth below should not be relied upon as such.

The SunCoke and SXCP projections summarized below were prepared by management of SunCoke. The SunCoke and SXCP projections were not prepared with a view toward public disclosure or toward compliance with generally accepted accounting principles (“GAAP”), the published guidelines of the SEC, or the guidelines established by the American Institute of Certified Public Accountants. Neither KPMG LLP (“KPMG”), nor any other independent registered public accounting firm, has compiled, examined or performed any procedures with respect to the prospective financial information contained in the projections, and accordingly, KPMG does not express an opinion or any other form of assurance with respect thereto. KPMG has not given advice or consultation in connection with the proposed Merger. The KPMG reports incorporated by reference into this joint prospectus/consent statement/proxy statement with respect to SunCoke and SXCP relate to historical financial information of SunCoke and SXCP, respectively. Such reports do not extend to the projections included below and should not be read to do so. Neither the SXCP Board nor the SunCoke Board prepared, and none of the SXCP Board, the SXCP Conflicts Committee, the SXCP General Partner, SXCP Board or the SunCoke Board gives any assurance regarding, the summarized information to any SXCP Common Unitholder or SunCoke Stockholder.

The financial projections are inherently subjective in nature, susceptible to interpretation and, accordingly, such projections may not be achieved. The financial projections also reflect numerous assumptions made by management, including material assumptions that may not be realized and are subject to significant uncertainties and contingencies, all of which are difficult to predict and many of which are beyond the control of the preparing party. SunCoke management also prepares financial projections that include prospective projects, which are risked based on the status of each project’s probability of success and final approval, among other factors. The financial projections that include risked prospective projects are reviewed alongside the other projections in the ordinary course. As noted therein, the financial projections presented to the SXCP Conflicts Committee included the effects of risked prospective projects. Prospective mergers and acquisitions were excluded from the financial projections. Accordingly, there can be no assurance that the assumptions made in preparing the financial projections upon which the foregoing projected financial information was based will be realized. There may be differences between actual and projected results, and the differences may be material. The risk that these uncertainties and contingencies could cause the assumptions to fail to be reflective of actual results is further increased by the length of time over which these assumptions apply. The failure to achieve assumptions and projections in early periods could have a compounding effect on the projections shown for the later periods. Thus, any such failure of an assumption or projection to be reflective of actual results in an early period could have a greater effect on the projected results failing to be reflective of actual events in later periods.

All of these assumptions involve variables making them difficult to predict, and some are beyond the control of SunCoke and SXCP. Although SunCoke’s management believes that there was a reasonable basis for its projections and underlying assumptions, any assumptions for near-term projected cases remain uncertain, and such uncertainty increases with the length of the projected period. The projections are forward-looking statements and are subject to risks and uncertainties. See the section titled “Information Regarding Forward-Looking Statements.”

In developing the financial projections provided to the SXCP Conflicts Committee, SunCoke’s management made numerous material assumptions with respect to SunCoke and SXCP for the fiscal years ending December 31, 2019 through 2023, including:

45

The summarized projected financial information set forth below was based on SunCoke’s and SXCP’s projected results for the fiscal years ending December 31, 2019 through 2023 with respect to the projections (may reflect rounding).

NEITHER SXCP NOR SUNCOKE INTEND TO UPDATE OR OTHERWISE REVISE THE ABOVE PROSPECTIVE FINANCIAL INFORMATION TO REFLECT CIRCUMSTANCES EXISTING AFTER THE DATE SUCH PROSPECTIVE FINANCIAL INFORMATION WAS PREPARED OR TO REFLECT THE OCCURRENCE OF SUBSEQUENT EVENTS, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING SUCH PROSPECTIVE FINANCIAL INFORMATION ARE NO LONGER APPROPRIATE.

Opinion of the SXCP Conflicts Committee’s Financial Advisor

The SXCP Conflicts Committee has engaged Citi to act as its financial advisor in connection with the proposed Merger. In connection with Citi’s engagement, the SXCP Conflicts Committee requested that Citi evaluate the fairness, from a financial point of view, of the Exchange Ratio provided for pursuant to the Merger Agreement. On February 4, 2019, at a meeting of the SXCP Conflicts Committee held to evaluate the proposed Merger, Citi rendered an oral opinion, confirmed by delivery of a written opinion dated February 4, 2019, to the SXCP Conflicts Committee to the effect that, as of that date and based on and subject to various assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken, the Exchange Ratio provided for pursuant to the Merger Agreement was fair, from a financial point of view, to holders of SXCP Public Units.

The full text of Citi’s written opinion, dated February 4, 2019, which describes the assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken, is attached as Annex B to this joint prospectus/consent statement/proxy statement and is incorporated into this joint prospectus/consent statement/proxy statement by reference. The description of Citi’s opinion set forth below is qualified in its entirety by reference to the full text of Citi’s opinion. Citi’s opinion was provided for the information of the SXCP Conflicts Committee (in its capacity as such) in connection with its evaluation of the Exchange Ratio from a financial point of view and did not address any other terms, aspects or implications of the Merger. Citi expressed no view as to, and its opinion did not address, the underlying business decision of SXCP General Partner to effect or enter into the Merger, the relative merits of the Merger as compared to any alternative business strategies that might exist for SXCP or the effect of any other transaction which SXCP might engage in or consider. Citi’s opinion is not intended to be and does not constitute a recommendation to any securityholder as to how such securityholder should vote or act on any matters relating to the proposed Merger or otherwise.

In arriving at its opinion, Citi:

47

In rendering its opinion, Citi assumed and relied, without independent verification, upon the accuracy and completeness of all financial and other information and data publicly available or provided to or otherwise reviewed by or discussed with Citi and upon the assurances of the managements and other representatives of SXCP General Partner and SunCoke that they were not aware of any relevant information that was omitted or that remained undisclosed to Citi. With respect to the financial forecasts and other information and data (including estimates as to the tax attributes of SunCoke on a standalone basis and after giving effect to the Merger as expected by the management of SunCoke to be utilized by SunCoke) that Citi was directed to utilize in its analyses, Citi was advised by the managements of SXCP General Partner and SunCoke, and Citi assumed, with the SXCP Conflicts Committee’s consent, that they were reasonably prepared on bases reflecting the best currently available estimates and judgments of such managements, as applicable, as to, and were a reasonable basis upon which to evaluate, the future financial performance of SXCP and SunCoke, the potential strategic implications and financial and operational benefits (including the amount, timing and achievability thereof) anticipated by the management of SunCoke to result from, and other potential pro forma financial effects of, the Merger and the other matters covered thereby. Citi expressed no view or opinion as to any financial forecasts and other information or data (or underlying assumptions on which any such financial forecasts and other information or data are based) provided to or otherwise reviewed by or discussed with Citi and Citi assumed, with the SXCP Conflicts Committee’s consent, that the financial results, including with respect to the potential strategic implications and financial and operational benefits anticipated to result from the Merger, reflected in such financial forecasts and other information and data would be realized in the amounts and at the times projected.

Citi relied, at the SXCP Conflicts Committee’s direction, upon the assessments of the managements of SXCP General Partner and SunCoke, as the case may be, as to, among other things, (i) the potential impact on SXCP and SunCoke of market, seasonal, cyclical, competitive and other trends and developments in and prospects for, and governmental, regulatory and legislative matters relating to or otherwise affecting, the coke production, coal, bulk terminaling and steel manufacturing industries and the geographic regions in which SXCP and SunCoke operate, including energy and commodity pricing and supply and demand for coal and steel, which are subject to significant volatility and which, if different than as assumed, could have a material impact on Citi’s analyses or opinion, (ii) existing and future contracts and relationships, agreements and arrangements with, and the ability to attract, retain and/or replace, key customers, employees, suppliers, service providers and other commercial relationships of SXCP and SunCoke, and (iii) the ability of SunCoke to integrate the operations of SXCP and SunCoke. Citi assumed, with the SXCP Conflicts Committee’s consent, that there would be no developments with respect to any such matters that would have an adverse effect on SXCP, SunCoke or the Merger (including the contemplated benefits thereof) or that otherwise would be meaningful in any respect to Citi’s analyses or opinion.

Citi did not make, and it was not provided with, an independent evaluation or appraisal of the assets or liabilities (contingent, accrued, derivative, off-balance sheet or otherwise) of SXCP, SunCoke or any other entity and Citi did not make any physical inspection of the properties or assets of SXCP, SunCoke or any other entity. Citi did not evaluate the solvency or fair value of SXCP, SunCoke or any other entity under any state, federal or other laws relating to bankruptcy, insolvency or similar matters. Citi expressed no view or opinion as to the potential impact on SXCP, SunCoke or any other entity of any pending or potential litigation, claims or governmental, regulatory or other proceedings, enforcement actions, consent decrees or other orders or investigations. Citi assumed, with the SXCP Conflicts Committee’s consent, that the Merger would be consummated in accordance with its terms and in compliance with all applicable laws, documents and other requirements, without waiver, modification or amendment of any material term, condition or agreement, and that, in the course of obtaining the

48

necessary governmental, regulatory or third party approvals, consents, releases, waivers and agreements for the Merger or otherwise, no delay, limitation, restriction, condition or other action, including any divestiture or other requirements, amendments or modifications, would be imposed or occur that would have an adverse effect on SXCP, SunCoke or the Merger (including the contemplated benefits thereof) or that otherwise would be meaningful in any respect to Citi’s analyses or opinion. Citi also assumed, with the SXCP Conflicts Committee’s consent, that the Merger would qualify for the intended tax treatment contemplated by the Merger Agreement. Citi’s opinion, as set forth therein, relates to the relative values of SXCP and SunCoke. Citi did not express any view or opinion as to the value of any securities (including SXCP Common Units or general partner interests and incentive distribution rights (“IDRs”) in SXCP) held by SunCoke, Merger Sub, SXCP General Partner, SXCP or their respective affiliates, the actual value of SunCoke Common Stock or any other securities when issued or retained in the Merger or the prices at which SunCoke Common Stock, SXCP Common Units or any other securities will trade or otherwise be transferable at any time, including following the announcement or consummation of the Merger. Representatives of SXCP General Partner advised Citi, and Citi further assumed, that the final terms of the Merger Agreement did not vary materially from those set forth in the draft reviewed by Citi. Citi did not express any view or opinion with respect to accounting, tax, regulatory, legal or similar matters, including, without limitation, as to tax or other consequences of the Merger or otherwise or changes in, or the impact of, tax and other laws, regulations and governmental and legislative policies affecting SXCP, SunCoke or the Merger (including the contemplated benefits thereof), and Citi relied, with the SXCP Conflicts Committee’s consent, upon the assessments of representatives of SXCP General Partner as to such matters.

Citi’s opinion addressed only the fairness, from a financial point of view and as of the date of such opinion, of the Exchange Ratio (to the extent expressly specified therein), without regard to individual circumstances of specific holders with respect to any rights, preferences, restrictions or limitations (whether by virtue of control, voting, liquidity or otherwise) which may distinguish such holders or the securities of SXCP held by such holders and Citi’s analyses and opinion did not address, take into consideration or give effect to any rights, preferences, restrictions or limitations that may be attributable to any such securities nor did Citi’s opinion in any way address any other consideration payable in connection with the Merger or proportionate allocation or relative fairness. Citi’s opinion did not address any terms (other than the Exchange Ratio to the extent expressly specified therein), aspects or implications of the Merger, including, without limitation, the form or structure of the Merger or any terms, aspects or implications of any support or other agreement, arrangement or understanding to be entered into in connection with or contemplated by the Merger or otherwise. In connection with Citi’s engagement, Citi was not requested to, and it did not, undertake a third-party solicitation process on behalf of SXCP with respect to the acquisition of all or a part of SXCP. Citi expressed no view as to, and its opinion did not address, the fairness (financial or otherwise) of the amount or nature or any other aspect of any compensation or other consideration to any officers, directors or employees of any parties to the Merger, or any class of such persons, relative to the Exchange Ratio or otherwise. Citi’s opinion was necessarily based upon information available, and financial, stock market and other conditions and circumstances existing and disclosed, to Citi as of the date of its opinion. Although subsequent developments may affect its opinion, Citi has no obligation to update, revise or reaffirm its opinion. As the SXCP Conflicts Committee was aware, the credit, financial and stock markets, and the industries in which SXCP and SunCoke operate, have experienced and continue to experience volatility and Citi expressed no view or opinion as to any potential effects of such volatility on SXCP, SunCoke or the Merger (including the contemplated benefits thereof). The issuance of Citi’s opinion was authorized by Citi’s fairness opinion committee.

In preparing its opinion, Citi performed a variety of financial and comparative analyses, including those described below. The summary of the analyses below is not a complete description of Citi’s opinion or the analyses underlying, and factors considered in connection with, Citi’s opinion. The preparation of a financial opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a financial opinion is not readily susceptible to summary description. Citi arrived at its ultimate opinion based on the results of all analyses and factors assessed as a whole, and it did not draw, in isolation, conclusions from or with regard to any one factor or method of analysis. Accordingly, Citi believes that the analyses must be

49

considered as a whole and that selecting portions of its analyses and factors or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying such analyses and its opinion.

In its analyses, Citi considered industry performance, general business, economic, market and financial conditions and other matters existing as of the date of its opinion, many of which are beyond the control of SXCP and SunCoke. No company, business or transaction reviewed is identical or directly comparable to SXCP, SunCoke or the Merger and an evaluation of these analyses is not entirely mathematical; rather, the analyses involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the public trading, acquisition or other values of the companies, businesses or transactions reviewed or the results from any particular analysis.

The estimates contained in Citi’s analyses and the ranges resulting from any particular analysis are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by such analyses. In addition, analyses relating to the value of businesses or securities do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold or acquired. Accordingly, the estimates used in, and the results derived from, Citi’s analyses are inherently subject to substantial uncertainty.

Citi was not requested to, and it did not, recommend or determine the specific consideration payable in the Merger. The type and amount of consideration payable in the Merger were determined through negotiations between the SXCP Conflicts Committee and SunCoke and the decision on behalf of SXCP to enter into the Merger Agreement was solely that of the SXCP Conflicts Committee and the SXCP Board. Citi’s opinion was only one of many factors considered by the SXCP Conflicts Committee in its evaluation of Exchange Ratio and should not be viewed as determinative of the views of the SXCP Conflicts Committee, the SXCP Board or SXCP General Partner management with respect to the Merger or the consideration payable in the Merger.

Financial Analyses

The summary of the financial analyses described below under this heading “—Financial Analyses” is a summary of the material financial analyses prepared and reviewed with the SXCP Conflicts Committee in connection with Citi’s opinion, dated February 4, 2019. The summary set forth below does not purport to be a complete description of the financial analyses performed by, and underlying the opinion of, Citi, nor does the order of the financial analyses described represent the relative importance or weight given to those financial analyses by Citi. Certain financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses, the tables must be read together with the text of each summary as the tables alone do not constitute a complete description of the financial analyses. Considering the data in the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the financial analyses, could create a misleading or incomplete view of such financial analyses. Future results may be different from those described and such differences may be material. For purposes of the financial analyses described below, the term (i) “adjusted EBITDA” refers to earnings before interest, taxes, depreciation and amortization, excluding certain non-recurring items, as applicable, and (ii) “SunCoke’s asset EBITDA” refers to adjusted EBITDA attributable to SunCoke excluding its limited partner interests in SXCP, referred to as LP interests, its general partner interests and related IDRs in SXCP, referred to as GP/IDR interests, and cash distributions made by Indiana Harbor in respect of non-controlling interests and related capital expenditure reimbursements. Approximate implied per unit and per share equity value reference ranges (other than such ranges derived from historical unit or stock trading histories and Wall Street research analysts’ unit or stock price targets) were rounded to the nearest $0.05 and approximate implied value reference ranges for SunCoke’s asset EBITDA and cash taxes were rounded to the nearest $5 million. Financial data utilized for SXCP and SunCoke in the financial analyses described below, to the extent based on financial forecasts and estimates of management, were based on financial forecasts and other information and data relating to SXCP and SunCoke provided to or discussed with

50

Citi by the respective managements of SXCP and SunCoke (in each case as reviewed and approved for Citi’s use by the SXCP Conflicts Committee), referred to in this section as the SXCP forecasts and SunCoke forecasts, respectively.

In calculating implied exchange ratio reference ranges as reflected in the financial analyses described below, other than the selected precedent transactions analysis, Citi divided the low-ends (or high-ends, as the case may be) of the approximate implied per unit equity value reference ranges derived for SXCP from such analyses by the high-ends (or low-ends, as the case may be) of the approximate implied per share equity value reference ranges derived for SunCoke from such analyses in order to calculate the low-ends (or high-ends) of the implied exchange ratio reference ranges. In calculating an implied exchange ratio reference range as reflected in the selected precedent transactions analysis described below, Citi divided the low-end (or high-end, as the case may be) of the approximate implied per unit equity value reference range derived for SXCP from such analysis by the high-end (or low-end, as the case may be) of the approximate implied per share equity value reference range derived for SunCoke from the selected public companies analysis of SunCoke described below in order to calculate the low-end (or high-end) of such implied exchange ratio reference range.

Selected Public Companies Analyses. Citi performed separate selected public companies analyses of SXCP (on a consolidated basis) and SunCoke (on a sum-of-the-parts basis) in which Citi reviewed certain financial and stock market information relating to SXCP, SunCoke and the selected publicly traded entities listed or referred to below.

SXCP. In its selected public companies analysis of SXCP, Citi reviewed certain financial and stock market information relating to SXCP and the following 12 selected publicly traded entities that Citi considered generally relevant, consisting of seven industrial process suppliers, referred to as the selected industrial process suppliers, one company with operations in the bulk terminaling industry, referred to as the selected bulk terminaling company, and four master limited partnerships, referred to as MLPs, with operations focused on the metals and mining industry, referred to as the selected M&M-focused MLPs, and, together with the selected industrial process suppliers and the selected bulk terminaling company, collectively referred to as the SXCP selected companies:

Selected Industrial Process Suppliers

Selected Bulk Terminaling Company

Selected M&M-Focused MLPs

Citi reviewed, among other information and to the extent publicly available, enterprise values, calculated, as applicable, as implied equity values based on closing unit or stock prices on February 1, 2019, plus implied general partner value, consolidated total debt, preferred equity and non-controlling interests and less consolidated cash and cash equivalents, as a multiple of calendar year 2019 and calendar year 2020 estimated adjusted

51

EBITDA. Financial data of the SXCP selected companies were based on publicly available Wall Street research analysts’ estimates and public filings. Financial data of SXCP was based on the SXCP forecasts, publicly available Wall Street research analysts’ estimates and public filings.

The overall low to high calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples observed for the selected industrial process suppliers were 4.4x to 8.3x (with a median of 6.8x) and 4.2x to 7.7x (with a median of 6.4x), respectively, and for the selected M&M-focused MLPs were 4.1x to 5.9x (with a median of 5.3x) and 4.2x to 6.3x (with a median of 5.3x), respectively. The calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples observed for the selected bulk terminaling company were 6.9x and 6.2x, respectively. Citi noted that the calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples for SXCP were 6.3x and 6.2x, respectively, based on publicly available Wall Street research analysts’ estimates. Citi then applied selected ranges of calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples derived from the SXCP selected companies of 5.7x to 7.0x and 5.4x to 6.5x, respectively, to corresponding data of SXCP based on the SXCP forecasts.

This analysis indicated an approximate implied per unit equity value reference range for SXCP of $9.15 to $15.00.

SunCoke. Citi performed a selected public companies analysis of SunCoke on a sum-of-the-parts basis to derive an approximate implied per share equity value reference range for SunCoke based on approximate implied values for (i) SunCoke’s asset EBITDA, (ii) SunCoke’s LP interests, and (iii) SunCoke’s GP/IDR interests.

In evaluating SunCoke’s asset EBITDA, Citi reviewed certain financial information relating to SunCoke’s asset EBITDA and certain financial and stock market information relating to the selected industrial process suppliers and the selected bulk terminaling company, collectively referred to as the SunCoke selected companies, including the overall low to high (and median) calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples observed for the selected industrial process suppliers and the calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples observed for the selected bulk terminaling company described above under “—Selected Public Companies Analyses—SXCP.” Financial data relating to SunCoke’s asset EBITDA was based on the SunCoke forecasts. Citi then applied selected ranges of calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples derived from the SunCoke selected companies of 6.2x to 7.6x and 5.6x to 6.9x, respectively, to SunCoke’s asset EBITDA. This analysis indicated an approximate implied value reference range for SunCoke’s asset EBITDA of $340 million to $415 million.

In evaluating SunCoke’s LP interests, Citi utilized the approximate implied per unit equity value reference range derived for SXCP of $9.15 to $15.00 from the selected public companies analysis of SXCP described above under “—Selected Public Companies Analyses—SXCP,” which indicated an approximate implied value reference range for SunCoke’s LP interests of $261 million to $427 million.

In evaluating SunCoke’s GP/IDR interests, Citi reviewed the calendar year 2019 estimated cash distributions associated with SunCoke’s GP/IDR interests and SXCP’s current (as of February 1, 2019) indicative distribution yield. Financial data of SunCoke’s GP/IDR interests was based on the SXCP forecasts and publicly available information. This analysis indicated an approximate implied value for SunCoke’s GP/IDR interests of $13 million.

The analyses described above for SunCoke on a sum-of-the-parts basis indicated an overall approximate implied per share equity value reference range for SunCoke of $10.85 to $14.60.

Utilizing the approximate implied per unit equity value reference range derived for SXCP and the overall approximate implied per share equity value reference range derived for SunCoke as described above, Citi calculated the following implied exchange ratio reference range, as compared to the Exchange Ratio:

52

Selected Precedent Transactions Analysis. Using publicly available information, Citi reviewed financial data relating to the following 18 selected transactions that Citi considered generally relevant as transactions involving acquisitions by general partners of their respective affiliated MLPs with operations in the natural resources industry, referred to as the SXCP selected precedent transactions:

Citi reviewed, among other information, the premiums implied by the consideration paid or proposed to be paid in the SXCP selected precedent transactions based on closing unit prices of the target partnerships involved in such transactions one trading day prior to the public announcement date of the relevant transaction and average closing unit prices of such target partnerships over the 30-day period prior to such announcement date. Financial data of the SXCP selected precedent transactions were based on public filings and other publicly available information. Unit price information of SXCP was based on publicly available market data.

The overall low to high one-day and average 30-day premiums observed for the SXCP selected precedent transactions were (3.9)% to 25.8% (with a mean of 8.8% and a median of 9.3%) and (8.7)% to 26.9% (with a mean of 10.1% and a median of 9.4%), respectively. Citi then applied selected ranges of premiums derived from the SXCP selected precedent transactions of 0% to 25.8% and 0% to 26.9% to SXCP’s closing unit price on February 1, 2019 and average closing unit prices over the 30-day period prior to February 1, 2019, respectively. This analysis indicated an approximate implied per unit equity value reference range for SXCP of $13.10 to $16.55.

Utilizing the approximate implied per unit equity value reference range derived for SXCP as described above and the overall approximate implied per share equity value reference range derived for SunCoke described above under “—Selected Public Companies Analyses—SunCoke,” Citi calculated the following implied exchange ratio reference range, as compared to the Exchange Ratio:

Discounted Cash Flow Analyses. Citi performed separate discounted cash flow analyses of SXCP (on a consolidated basis) and SunCoke (on a sum-of-the-parts basis).

SXCP. Citi performed a discounted cash flow analysis of SXCP by calculating the estimated present value of the unlevered free cash flows that SXCP was forecasted to generate during the fiscal years ending December 31, 2019 through December 31, 2023 based on the SXCP forecasts. Citi calculated implied terminal

53

values for SXCP by applying to SXCP’s fiscal year 2023 estimated adjusted EBITDA a selected range of terminal adjusted EBITDA multiples of 5.7x to 7.0x. The present values (as of January 1, 2019) of the cash flows and terminal values were then calculated using a selected range of discount rates of 8.3% to 9.8%. This analysis indicated an approximate implied per unit equity value reference range for SXCP of $14.10 to $19.60.

SunCoke. Citi performed a discounted cash flow analysis of SunCoke on a sum-of-the-parts basis to derive an approximate implied per share equity value reference range for SunCoke based on approximate implied values for (i) SunCoke’s asset EBITDA, (ii) SunCoke’s LP interests and (iii) SunCoke’s GP/IDR interests, after taking into account SunCoke’s estimated cash taxes, based on the SunCoke forecasts.

In evaluating SunCoke’s asset EBITDA, Citi performed a discounted cash flow analysis of SunCoke’s asset EBITDA by calculating the estimated present value of the unlevered free cash flows associated with SunCoke’s asset EBITDA during the fiscal years ending December 31, 2019 through December 31, 2023 based on the SunCoke forecasts. Citi calculated terminal values for SunCoke’s asset EBITDA by applying to SunCoke’s estimated asset EBITDA for fiscal year 2023 a selected range of terminal adjusted EBITDA multiples of 6.2x to 7.6x. The present values (as of January 1, 2019) of the cash flows and terminal values were then calculated using a selected range of discount rates of 10.3% to 11.6%. This analysis indicated an approximate implied value reference range for SunCoke’s asset EBITDA of $350 million to $420 million.

In evaluating SunCoke’s LP interests, Citi utilized the approximate implied per unit equity value reference range derived for SXCP of $14.10 to $19.60 from the discounted cash flow analysis of SXCP described above under “—Discounted Cash Flow Analyses—SXCP,” which indicated an approximate implied aggregate value reference range for SunCoke’s LP interests of $402 million to $559 million.

In evaluating SunCoke’s GP/IDR interests, Citi utilized the approximate implied value derived for SunCoke’s GP/IDR interests of $13 million from the analysis of SunCoke’s GP/IDR interests described above under “—Selected Public Companies Analyses—SunCoke.”

In evaluating SunCoke’s cash taxes, Citi performed a discounted cash flow analysis of SunCoke’s cash taxes by calculating the estimated present value of such cash taxes, taking into account SunCoke’s expected utilization of tax attributes, during the fiscal years ending December 31, 2019 through December 31, 2023 based on the SunCoke forecasts. Citi calculated a terminal value for such cash taxes assuming no growth in SunCoke’s cash taxes after the fiscal year ending December 31, 2023. The present values (as of January 1, 2019) of the cash taxes and terminal values were then calculated using a selected range of discount rates of 11.8% to 15.0%. This analysis indicated an approximate implied value reference range for SunCoke’s cash taxes of $145 million to $190 million.

The analyses described above for SunCoke on a sum-of-the-parts basis indicated an overall approximate implied per share equity value reference range for SunCoke of $10.95 to $13.75.

Utilizing the approximate implied per unit equity value reference range derived for SXCP and the overall approximate implied per share equity value reference range derived for SunCoke as described above, Citi calculated the following implied exchange ratio reference range, as compared to the Exchange Ratio:

Has/Gets. Citi compared the approximate implied per unit equity value reference ranges derived for SXCP on a standalone basis described above under “—Selected Public Companies Analyses—SXCP” and “—Discounted Cash Flow Analyses—SXCP” relative to illustrative approximate implied per unit equity values on a pro forma basis derived from a selected public companies analysis and a discounted cash flow analysis of the combined company based on the Exchange Ratio and after taking into account the potential cost savings anticipated by the

54

management of SunCoke to result from the Merger. Citi utilized, in the case of such selected public companies analysis, selected ranges of calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples of 5.7x to 7.6x and 5.4x to 6.9x, respectively, and, in the case of such discounted cash flow analysis, a selected range of terminal adjusted EBITDA multiples of 5.7x to 7.6x and a selected range of discount rates of 8.3% to 9.8%. Financial data of SXCP was based on the SXCP forecasts and public filings. Financial data of the pro forma combined company was based on the SXCP forecasts, SunCoke forecasts and public filings.

Citi observed that the pro forma ownership of SXCP Public Unitholders in the combined company implied by the Exchange Ratio indicated that the Merger could result in approximate implied per unit equity values on a pro forma basis derived from the selected public companies analysis and discounted cash flow analysis described above of $13.15 to $20.65 and $16.25 to $23.25, respectively (relative to $9.15 to $15.00 and $14.10 to $19.60, respectively, on a standalone basis). Actual results achieved by SXCP, SunCoke and the pro forma combined company may vary from forecasted results and variations may be material.

Certain Additional Information

Citi also observed certain additional information that was not considered part of its financial analyses with respect to its opinion but was noted for informational purposes, including the following:

Actual results achieved by SXCP, SunCoke and the pro forma combined company may vary from forecasted results and variations may be material.

Miscellaneous

SXCP has agreed to pay Citi for its services in connection with the proposed Merger an aggregate fee of $3 million, of which a portion was payable upon Citi’s engagement, a portion was payable upon the delivery of

55

Citi’s opinion and $2.5 million is payable contingent upon consummation of the Merger. SXCP also has agreed to reimburse Citi for Citi’s expenses, including fees and expenses of counsel, and to indemnify Citi and related parties against certain liabilities, including liabilities under federal securities laws, arising from Citi’s engagement.

As the SXCP Conflicts Committee was aware, Citi and its affiliates in the past have provided, currently are providing and in the future may provide investment banking, commercial banking and other similar financial services to SXCP, SXCP General Partner, SunCoke and/or certain of their respective affiliates unrelated to the proposed Merger, for which services Citi and its affiliates received and expect to receive compensation, including, during the two-year period prior to the date of Citi’s opinion, having acted or acting (i) in the case of SXCP, as (a) joint book-running manager and an initial purchaser for a debt offering of SXCP and an affiliate thereof and (b) a lender under a credit facility of SXCP and certain of its affiliates and (ii) in the case of SunCoke, as (a) a lender under a credit facility of SunCoke and (b) agent on behalf of SunCoke in connection with certain purchases of SXCP Common Units. For the services described in clauses (i) and (ii) above, Citi and its affiliates received during such two-year period aggregate fees of approximately $1.5 million from SXCP and SunCoke. In the ordinary course of business, Citi and its affiliates may actively trade or hold the securities of SXCP, SunCoke and their respective affiliates for their own account or for the account of customers and, accordingly, may at any time hold a long or short position in such securities. In addition, Citi and its affiliates (including Citigroup Inc. and its affiliates) may maintain relationships with SunCoke, SXCP General Partner, SXCP and their respective affiliates.

The SXCP Conflicts Committee selected Citi to act as financial advisor in connection with the proposed Merger based on Citi’s reputation, experience and familiarity with SXCP, SunCoke and their respective businesses. Citi is an internationally recognized investment banking firm that regularly engages in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes.

Recommendation of the SunCoke Board and Its Reasons for the Merger

On February 4, 2019, the SunCoke Board (i) determined that the Merger Agreement and the transactions contemplated thereby, including the Merger and the Parent Stock Issuance, are in the best interests of SunCoke and its stockholders, (ii) approved and declared advisable the Merger Agreement and the transactions contemplated thereby, including the Merger and the Parent Stock Issuance, and (iii) resolved to submit the Parent Stock Issuance to a vote of SunCoke’s stockholders and recommend approval of the Parent Stock Issuance.

The SunCoke Board considered many factors in making its determination and recommendation. The SunCoke Board consulted with its financial and legal advisors and viewed the following factors as being generally positive or favorable in coming to its determination and related recommendation:

56

The following factors are generally negative or unfavorable in making a determination and recommendation with respect to the Merger:

57

There is risk that the Merger might not be completed in a timely manner, or that the Merger might not be consummated at all as a result of a failure to satisfy the conditions contained in the Merger Agreement, including as a result of a failure to obtain Parent Stock Issuance Approval, and a failure to complete the Merger could negatively affect the trading price of SunCoke Common Stock.

After taking into account all of the factors set forth above, as well as others, the SunCoke Board concluded that the potential benefits of the Merger outweighed any negative or unfavorable considerations and determined that the Merger Agreement and the transactions contemplated thereby, including, without limitation, the Merger and the Parent Stock Issuance, are in the best interests of SunCoke and its stockholders.

The foregoing discussion is not intended to be exhaustive, but is intended to address the material information and principal factors considered by the SunCoke Board in considering the Merger. In view of the number and variety of factors and the amount of information considered, the SunCoke Board did not find it practicable to, and did not make specific assessments of, quantify or otherwise assign relative weights to, the specific factors considered in reaching its determination. In addition, the SunCoke Board did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was favorable or unfavorable to its ultimate determination, and individual members of the SunCoke Board may have given different weights to different factors. The SunCoke Board made its recommendation based on the totality of information presented to, and the investigation conducted by, the SunCoke Board. It should be noted that certain statements and other information presented in this section are forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading “Information Regarding Forward-Looking Statements.”

Opinion of SunCoke’s Financial Advisor

The SunCoke Board retained Evercore to act as financial advisor to the SunCoke Board in connection with evaluating the Merger. On February 4, 2019, at a meeting of the SunCoke Board and at the request of the SunCoke Board, Evercore rendered its oral opinion to the SunCoke Board that, as of February 4, 2019, and based upon and subject to the factors, procedures, assumptions, qualifications and limitations set forth in its opinion, the Exchange Ratio is fair, from a financial point of view, to SunCoke. Evercore subsequently confirmed its oral opinion in a written opinion on the same date.

The full text of the written opinion of Evercore, dated as of February 4, 2019, which sets forth, among other things, the procedures followed, assumptions made, matters considered and qualifications and limitations on the scope of review undertaken in rendering its opinion, is attached hereto as Annex C to this joint prospectus/consent statement/proxy statement. You are urged to read Evercore’s opinion carefully and in its entirety. Evercore’s opinion was addressed to, and provided for the information and benefit of, the SunCoke Board in connection with its evaluation of the fairness of the Exchange Ratio from a financial point of view to SunCoke, and did not address any other aspects or implications of the Merger. Evercore’s opinion should not be construed as creating any fiduciary duty on Evercore’s part to any party and such opinion is not intended to be, and does not constitute, a recommendation to the SunCoke Board or to any other persons in respect of the Merger, including as to how any SunCoke Stockholder or SXCP unitholder should act or vote in respect of the Parent Stock Issuance Proposal or the Merger, as applicable. The summary of the Evercore opinion set forth herein is qualified in its entirety by reference to the full text of the opinion included as Annex C.

In connection with rendering its opinion and performing its related financial analysis, Evercore, among other things:

58

For purposes of its analysis and opinion, Evercore assumed and relied upon, without undertaking any independent verification of, the accuracy and completeness of all of the information publicly available, and all of the information supplied or otherwise made available to, discussed with, or reviewed by Evercore, and Evercore assumes no liability therefor. With respect to the projected financial and operating data relating to SunCoke and SXCP referred to above and the Projected Cost Savings and Synergies, Evercore assumed that such data was reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of management of SunCoke and SXCP as to the future financial performance of SunCoke and SXCP under the assumptions reflected therein. Evercore did not express a view as to any projected financial data relating to SunCoke or SXCP or the Projected Cost Savings and Synergies or the assumptions on which they are based. Evercore has relied, at the direction of the SunCoke Board, without independent verification, upon the assessments of the management of SunCoke and SXCP as to the future financial and operating performance of SunCoke and SXCP.

For purposes of rendering its opinion, Evercore assumed, in all respects material to its analysis, that the representations and warranties of each party contained in the Merger Agreement are true and correct, that each party will perform all of the covenants and agreements required to be performed by it under the Merger Agreement, that all conditions to the consummation of the Merger will be satisfied without material waiver or modification thereof, and that the Exchange Ratio will not be adjusted from 1.40 shares of SunCoke Common

59

Stock per SXCP Common Unit. Evercore has further assumed, in all respects material to its analysis, that all governmental, regulatory or other consents, approvals or releases necessary for the consummation of the Merger will be obtained without any material delay, limitation, restriction or condition.

Evercore did not make, nor assume any responsibility for making any independent valuation or appraisal of any assets or liabilities of SunCoke or SXCP, nor was Evercore furnished with any such valuations or appraisals, nor did Evercore evaluate the solvency or fair value of SunCoke or SXCP under any state or federal laws relating to bankruptcy, insolvency or similar matters. Evercore’s opinion was necessarily based upon information made available to Evercore as of the date of its opinion and financial, economic, monetary, market, regulatory and other conditions and circumstances as they existed and as could be evaluated by Evercore on the date of its opinion. It is understood that subsequent developments or information of which Evercore was not aware may affect this opinion and that Evercore does not have any obligation to update, revise or reaffirm its opinion.

Evercore was not asked to pass upon, and expressed no opinion with respect to, any matter other than the fairness, as of the date of its opinion, of the Exchange Ratio to SunCoke, from a financial point of view. Evercore did not express any view on, and its opinion does not address, the fairness of the Merger to, or any exchange ratio received in connection therewith by, the holders of any securities, creditors or other constituencies of SunCoke or SXCP, nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of SunCoke or SXCP, or any class of such persons, whether relative to the Exchange Ratio or otherwise. Evercore assumed that any modification to the structure of the Merger Agreement would not vary in any respect material to its analysis. Evercore’s opinion did not address the relative merits of the Merger as compared to other business or financial strategies that might have been available to SunCoke or SXCP, nor did it address the underlying business decision of SunCoke to engage in the Merger. In arriving at its opinion, Evercore was not authorized to solicit, and did not solicit, interest from any third party with respect to any other extraordinary transaction involving SunCoke or SXCP. Evercore’s opinion did not constitute a recommendation to SunCoke or to any other persons in respect of the Merger, including as to how any holder of shares of the SunCoke Common Stock should vote in respect of the Parent Stock Issuance Proposal or the Merger, as applicable. Evercore expressed no opinion as to the price at which the shares of the SunCoke Common Stock would trade at any time. Evercore is not a legal, regulatory, accounting or tax expert and assumed the accuracy and completeness of assessments by SunCoke, SXCP and their advisors with respect to legal, regulatory, accounting and tax matters.

Set forth below is a summary of the material financial analyses performed by Evercore and reviewed with the SunCoke Board on February 4, 2019, in connection with rendering Evercore’s opinion to the SunCoke Board. Each analysis was provided to the SunCoke Board. The following summary, however, does not purport to be a complete description of the analyses performed by Evercore. In connection with arriving at its opinion, Evercore considered all of its analyses as a whole, and the order of the analyses described and the results of these analyses do not represent any relative importance or particular weight given to these analyses by Evercore. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data that existed on February 1, 2019, and is not necessarily indicative of current market conditions.

Analysis of SXCP

Assumptions with Respect to SXCP

Evercore performed a series of analyses to derive indicative valuation ranges for the SXCP Common Units. Evercore performed its analyses utilizing the financial projections for SXCP provided by management of SXCP (the “SXCP Financial Projections”). A summary of the SXCP Financial Projections are available in “The Merger—Unaudited Financial Projections of SunCoke and SXCP” above. The SXCP Financial Projections were not adjusted by Evercore.

Discounted Cash Flow Analysis

Evercore performed a discounted cash flow analysis of SXCP by valuing the cash flows to be received by SXCP based on the SXCP Financial Projections. Evercore calculated the per unit value range for SXCP Public Units by utilizing a range of discount rates based on SXCP’s Weighted Average Cost of Capital (“WACC”), as estimated by Evercore based on the Capital Asset Pricing Model (“CAPM”) and SXCP’s non-traditional MLP and bulk terminal MLP peers, and terminal values based on a range of estimated EBITDA exit multiples and perpetuity growth rates. Evercore assumed a range of discount rates of 8.0% to 9.5%, a range of EBITDA exit multiples of 7.5x to 9.5x and a range of perpetuity growth rates of 0.0% to 2.0%. For both the EBITDA exit multiple and perpetuity growth rate methodologies, Evercore adjusted the SXCP Public Unit value to incorporate the net present value of the projected cash tax benefit resulting from remedial income allocations to SunCoke (“Remedial Allocations”), which result in the holders of SXCP Public Units being allocated less than their pro-rata share of SXCP’s income, based on a 10.0% equity cost of capital, which was derived from the CAPM utilizing SXCP’s non-traditional MLP and bulk terminal MLP peers and Evercore’s professional judgment. The Discounted Cash Flow analysis utilizing the EBITDA exit multiple methodology to calculate terminal value resulted in an implied equity value per SXCP Public Unit range of $17.91 to $26.09. The Discounted Cash Flow Analysis utilizing the perpetuity growth rate methodology to calculate terminal value resulted in an implied equity value per SXCP Public Unit range of $11.07 to $22.45.

Precedent M&A Transaction Analysis

Evercore reviewed selected transactions that Evercore deemed to have certain characteristics similar to those of SXCP, including transactions involving (i) fee-based raw materials processing assets and (ii) bulk terminal assets.

Evercore reviewed transactions involving fee-based raw materials processing assets announced since January 2014 and selected eight transactions involving assets that Evercore deemed to have certain characteristics that are similar to those of SXCP’s cokemaking assets, although Evercore noted that none of the selected transactions or the selected companies or partnerships that participated in the selected transactions were directly comparable to SXCP’s cokemaking assets:

Evercore noted that the mean and median of the implied Enterprise Value (defined below) to EBITDA multiples for the selected fee-based raw materials processing transactions were equal to 7.6x and 7.7x, respectively.

61

Evercore reviewed selected transactions involving bulk terminal infrastructure assets announced since December 2012 and selected 18 transactions involving assets that Evercore deemed to have certain characteristics that are similar to those of SXCP’s logistics assets, although Evercore noted that none of the selected transactions or the selected companies or partnerships that participated in the selected transactions were directly comparable to SXCP’s logistics assets:

Evercore noted that the mean and median of the implied Enterprise Value to EBITDA multiples for the selected bulk terminal transactions were each equal to 8.2x.

Based on Evercore’s review of the selected precedent transactions, Evercore derived a range of relevant implied multiples of Enterprise Value to EBITDA of 7.0x to 8.5x for fee-based raw materials processing precedent transactions and 7.0x to 9.0x for bulk terminals precedent transactions. Evercore then applied these ranges of selected multiples to 2018 adjusted EBITDA for each of SXCP’s relevant businesses. After adjusting for debt and cash as of January 1, 2019, and dividing by total units outstanding as of January 1, 2019, Evercore determined a range of value per SXCP Common Unit of $15.94 to $23.70.

Peer Group Trading Analysis

Evercore performed a peer group trading analysis of SXCP by reviewing and comparing the market values and trading multiples of the following five publicly traded partnerships that Evercore deemed to have certain characteristics that are similar to those of SXCP, including size and asset base, divided into non-traditional master limited partnerships (“MLPs”) and bulk terminals MLPs:

Non-Traditional MLPs:

Bulk Terminals MLPs:

Although the peer groups were utilized to value the SXCP Public Units for purposes of this analysis, no partnership used in the Peer Group Trading Analysis is identical or directly comparable to SXCP. In order to calculate peer group trading multiples, Evercore relied on publicly available filings with the SEC and equity research analyst estimates.

For each of the peer group partnerships, Evercore calculated the following trading multiples:

The mean and median Enterprise Value to EBITDA trading multiples of the non-traditional and bulk terminals MLPs are set forth below. The table also includes relevant multiple ranges selected by Evercore based on the resulting range of Enterprise Value to EBITDA multiples and certain other considerations related to the specific characteristics of SXCP noted by Evercore.

After adjusting for debt and cash as of January 1, 2019, and dividing by total units outstanding as of January 1, 2019, Evercore determined an implied equity value per SXCP Common Unit range of (i) $18.54 to $26.23 based on 2019 adjusted EBITDA and (ii) $17.52 to $22.34 based on 2020 adjusted EBITDA.

Analysis of SunCoke

Assumptions with Respect to SunCoke

Evercore performed a series of analyses to derive indicative valuation ranges for shares of the SunCoke Common Stock. Evercore performed its analyses utilizing the financial projections for SunCoke provided by management of SunCoke (the “SunCoke Financial Projections”). A summary of the SunCoke Financial Projections are available in “The Merger—Unaudited Financial Projections of SunCoke and SXCP” above. The SunCoke Financial Projections were not adjusted by Evercore.

Discounted Cash Flow Analysis

Evercore performed a discounted cash flow analysis of SunCoke to derive a range of implied value per share of SunCoke Common Stock utilizing the SunCoke Financial Projections based on: (i) a discounted cash flow analysis of SunCoke’s directly-held assets; (ii) the implied value of the SXCP Common Units owned by SunCoke based on the SXCP Discounted Cash Flow Analysis, excluding the adjustment to the SXCP Public Units for Remedial Allocations, and (iii) the value of SunCoke’s general partner interest in SXCP implied by the Precedent M&A Transaction Analysis for SunCoke, as described further below.

For the discounted cash flow analysis of SunCoke’s directly-held assets, Evercore calculated ranges of implied enterprise value of SunCoke’s directly-held assets utilizing a range of discount rates based on SunCoke’s WACC, as estimated by Evercore based on the CAPM and SunCoke’s steel-supplier and steel producer peers and Evercore’s professional judgment, and terminal values based on a range of estimated EBITDA exit multiples as well as perpetuity growth rates. Evercore assumed a range of discount rates of 11.0% to 13.0%, a range of EBITDA exit multiples of 5.5x to 7.5x and a range of perpetuity growth rates of 0.0% to 2.0%. Evercore then added the implied values of the SXCP Common Units owned by SunCoke, derived from the Discounted Cash Flow Analysis of SXCP, and the implied values of SunCoke’s general partner interest in SXCP, derived from the SunCoke Precedent M&A Transaction Analysis (described below), to the implied enterprise value ranges based on the discounted cash flow analysis of SunCoke’s directly-held assets to derive ranges of SunCoke’s total enterprise value. Evercore then added the SunCoke’s net cash as of January 1, 2019, and subtracted SunCoke’s liability for pneumoconiosis benefits as of January 1, 2019, as provided by management of SunCoke, to derive implied ranges of SunCoke’s equity value. Evercore then divided the ranges of implied equity values of SunCoke by the number of fully-diluted shares of SunCoke Common Stock outstanding as of January 1, 2019, to derive ranges of implied values per share of the SunCoke Common Stock. Evercore then subtracted the net present value of the projected cash tax expense resulting from Remedial Allocations utilizing a discount rate of 12.0% based on SunCoke’s WACC from the implied values per share of SunCoke Common Stock.

The Discounted Cash Flow analysis utilizing the EBITDA exit multiple methodology to calculate terminal value resulted in a range of implied equity value per share of SunCoke Common Stock of $12.64 to $18.27. The Discounted Cash Flow Analysis utilizing the perpetuity growth rate methodology to calculate terminal value resulted in a range of implied equity value per share of SunCoke Common Stock of $8.74 to $15.63.
