Forward-Looking Statements

Some of the information included in this presentation constitutes “forward-looking statements” as defined in Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended. All statements in this presentation that express opinions, expectations, beliefs, plans, objectives, assumptions or projections with respect to anticipated future performance of SunCoke

Energy, Inc. (“SunCoke”) or SunCoke Energy Partners, L.P. (“Partnership”), in contrast with statements of historical facts, are forward-looking statements. Such forward-looking statements are based on management’s beliefs and assumptions and on information currently available. Forward-looking statements include information concerning possible or assumed future results of operations, business strategies, financing plans, competitive position, potential growth opportunities, potential operating performance improvements, the effects of competition and the effects of future legislation or regulations. Forward-looking statements include all statements that are not historical facts and may be identified by the use of forward-looking terminology such as the words “believe,” “expect,” “plan,” “intend,” “anticipate,” “estimate,” “predict,” “potential,” “continue,” “may,” “will,” “should” or the negative of these terms or similar expressions.

Although management believes that its plans, intentions and expectations reflected in or suggested by the forward-looking statements made in this presentation are reasonable, no assurance can be given that these plans, intentions or expectations will be achieved when anticipated or at all. Moreover, such statements are subject to a number of assumptions, risks and uncertainties. Many of these risks are beyond the control of SunCoke and the Partnership, and may cause actual results to differ materially from those implied or expressed by the forward-looking statements. Each of SunCoke and the Partnership has included in its filings with the Securities and Exchange Commission (including, in the case of the Partnership, its Form S-1) cautionary language identifying important factors (but not necessarily all the important factors) that could cause actual results to differ materially from those expressed in any forward-looking statement. For more information concerning these factors, see the Securities and Exchange Commission filings of SunCoke and the Partnership. All forward-looking statements included in this presentation are expressly qualified in their entirety by such cautionary statements. Although forward-looking statements are based on current beliefs and expectations, caution should be taken not to place undue reliance on any such forward-looking statements because such statements speak only as of the date hereof. Neither SunCoke nor the Partnership has any intention or obligation to update publicly any forward-looking statement (or its associated cautionary language) whether as a result of new information or future events or after the date of this presentation, except as required by applicable law.

Reconciliations of non-GAAP financial measures to GAAP financial measures are provided in the Appendix at the end of the presentation. Investors are urged to consider carefully the comparable GAAP measures and the reconciliations to those measures provided in the Appendix.

Definitions

Adjusted EBITDA represents earnings before interest, taxes, depreciation, depletion and amortization (“EBITDA”) adjusted for sales discounts and the interest, taxes, depreciation, depletion and amortization attributable to our equity method investment.

EBITDA reflects sales discounts included as a reduction in sales and other operating revenue. The sales discounts represent the sharing with customers of a portion of nonconventional fuel tax credits, which reduce our income tax expense. However, we believe our Adjusted EBITDA would be inappropriately penalized if these discounts were treated as a reduction of EBITDA since they represent sharing of a tax benefit that is not included in EBITDA. Accordingly, in computing Adjusted EBITDA, we have added back these sales discounts. Our Adjusted EBITDA also includes EBITDA attributable to our equity method investment. EBITDA and Adjusted EBITDA do not represent and should not be considered alternatives to net income or operating income under GAAP and may not be comparable to other similarly titled measures in other businesses. Management believes Adjusted EBITDA is an important measure of the operating performance of the Company’s net assets. We believe Adjusted EBITDA is an important measure of operating performance and provides useful information to investors because it highlights trends in our business that may not otherwise be apparent when relying solely on GAAP measures and because it eliminates items that have less bearing on our operating performance. Adjusted EBITDA is a measure of operating performance that is not defined by GAAP, does not represent and should not be considered a substitute for net income as determined in accordance with GAAP. Calculations of Adjusted EBITDA may not be comparable to those reported by other companies.

EBITDA represents earnings before interest, taxes, depreciation, depletion and amortization.

Adjusted EBITDA attributable to SXC/SXCP equals Adjusted EBITDA less Adjusted EBITDA attributable to noncontrolling interests.

Adjusted EBITDA/Ton represents Adjusted EBITDA divided by tons sold. When applicable to Adjusted EBITDA attributable to SXC or SXCP, tons sold are prorated according to the respective ownership interest of SXC or SXCP as applicable.

2013 Citi One-on-One MLP / Midstream

27

Definitions

Distributable Cash Flow equals Adjusted EBITDA less net cash paid for interest expense, on-going capital expenditures, accruals for replacement capital expenditures, and cash distributions to noncontrolling interests. Distributable Cash Flow is a non-GAAP supplemental financial measure that management and external users of the Partnership’s financial statements, such as industry analysts, investors, lenders and rating agencies use to assess:

the Partnership’s operating performance as compared to other publicly traded partnerships, without regard to historical cost basis;

the ability of the Partnership’s assets to generate sufficient cash flow to make distributions to the Partnership’s unitholders;

the Partnership’s ability to incur and service debt and fund capital expenditures; and

the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.

The Partnership believes that Distributable Cash Flow provides useful information to investors in assessing the Partnership’s financial condition and results of operations. Distributable Cash Flow should not be considered an alternative to net income, operating income, cash flows from operating activities, or any other measure of financial performance or liquidity presented in accordance with generally accepted accounting principles (GAAP). Distributable Cash Flow has important limitations as an analytical tool because it excludes some, but not all, items that affect net income and net cash provided by operating activities and used in investing activities.

Additionally, because Distributable Cash Flow may be defined differently by other companies in the industry, the Partnership’s definition of Distributable Cash Flow may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

Ongoing capital expenditures (“capex”) are capital expenditures made to maintain the existing operating capacity of our assets and/or to extend their useful lives. Ongoing capex also include new equipment that improves the efficiency, reliability or effectiveness of existing assets. Ongoing capex does not include normal repairs and maintenance, which are expensed as incurred, or significant capital expenditures. For purposes of calculating distributable cash flow, the portion of ongoing capex attributable to SXCP is used.

Replacement capital expenditures (“capex”) represents an annual accrual necessary to fund SXCP’s share of the estimated costs to replace or rebuild our facilities at the end of their working lives. This accrual is estimated based on the average quarterly anticipated replacement capital that we expect to incur over the long term to replace our major capital assets at the end of their working lives. The replacement capex accrual estimate will be subject to review and prospective change by SXCP’s general partner at least annually and whenever an event occurs that causes a material adjustment of replacement capex, provided such change is approved by our conflicts committee.
