Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On January 10, 2012, SunCoke Energy, Inc. (the “Company”) indicated that after a preliminary review of 2011 results, the Company estimates 2011 Adjusted EBITDA will be between $148 million and $153 million.

An investor presentation prepared by the Company is attached hereto as Exhibit 99.1 and incorporated herein by reference.

The information in this Current Report on Form 8-K being furnished pursuant to Items 2.02, 7.01 and 9.01 shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section, and is not incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.

DEFINITIONS

This Current Report on Form 8-K includes Adjusted EBITDA, which is a non-GAAP measure. Adjusted EBITDA represents earnings before interest, taxes, depreciation, depletion and amortization (“EBITDA”) adjusted for sales discounts and the deduction of income attributable to non-controlling interests in the Company’s Indiana Harbor cokemaking operations. EBITDA reflects sales discounts included as a reduction in sales and other operating revenue. The sales discounts represent the sharing with the Company’s customers of a portion of nonconventional fuels tax credits, which reduce our income tax expense. However, the Company believes that its Adjusted EBITDA would be inappropriately penalized if these discounts were treated as a reduction of EBITDA since they represent sharing of a tax benefit which is not included in EBITDA. Accordingly, in computing Adjusted EBITDA, the Company has added back these sales discounts. The Company’s Adjusted EBITDA also reflects the deduction of income attributable to noncontrolling interest in its Indiana Harbor cokemaking operations. 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 of other businesses. Management believes Adjusted EBITDA is an important measure of the operating performance of the Company’s assets and is indicative of the Company’s ability to generate cash from operations.

         Non-GAAP financial measures are intended to supplement, not substitute for, comparable GAAP measures. Reconciliations of non-GAAP financial measures to GAAP financial measures are provided in the investor presentation attached hereto as Exhibit 99.1 and incorporated herein by reference. Investors are urged to consider carefully the comparable GAAP measures and the reconciliations to those measures provided in such Exhibit 99.1.

Unpredictable or unknown factors not discussed in this Current Report on Form 8-K also could have material adverse effects on forward-looking statements.

In accordance with the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, the Company has included in its filings with the Securities and Exchange Commission 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 made by the Company. For more information concerning these factors, see the Company’s Securities and Exchange Commission filings. All forward-looking statements included in this Current Report on Form 8-K are expressly qualified in their entirety by such cautionary statements. The Company undertakes no obligation to update publicly any forward-looking statement (or its associated cautionary language) whether as a result of new information or future events or otherwise.
