FORWARD-LOOKING STATEMENTS This press release and related conference call contain “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). Forward-looking statements often may be identified by the use of such words as "believe," "expect," "plan," "project," "intend," "anticipate," "estimate," "predict," "potential," "continue," "may," "will," "should," or the negative of these terms, or similar expressions. However, the absence of these words or similar expressions does not mean that a statement is not forward-looking. Any statements made in this press release or during the related conference call that are not statements of historical fact, including those concerning possible or assumed future results of operations, our 2026 guidance and outlook, our expectation to continue a quarterly dividend, descriptions of our business plans and strategies, and other statements about our beliefs and expectations, are forward-looking statements and should be evaluated as such. Forward-looking statements represent only our present beliefs regarding future events, many of which are inherently uncertain and involve significant known and unknown risks and uncertainties (many of which are beyond the control of SunCoke) that could cause our actual results and financial condition to differ materially from the anticipated results and financial condition indicated in such forward-looking statements. These risks and uncertainties include, but are not limited to, the risks and uncertainties described in Item 1A (“Risk Factors”) of our Annual Report on Form 10-K for the most recently completed fiscal year, as well as those described from time to time in our other reports and filings with the Securities and Exchange Commission (SEC). In accordance with the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, SunCoke has included in its filings with the SEC 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 SunCoke. For information concerning these factors and other important information regarding the matters discussed in this press release and related conference call, see SunCoke's SEC filings, copies of which are available free of charge on SunCoke's website at www.suncoke.com or on the SEC's website at www.sec.gov. All forward-looking statements included in this press release and related

WL Carter_PressRel_2026_0916a_v02.docx Page 3 of 3 conference call are expressly qualified in their entirety by such cautionary statements. Unpredictable or unknown factors not discussed in this press release and related conference call also could have material adverse effects on forward-looking statements. Forward-looking statements are not guarantees of future performance, but are based upon the current knowledge, beliefs and expectations of SunCoke management, and upon assumptions by SunCoke concerning future conditions, any or all of which ultimately may prove to be inaccurate. You should not place undue reliance on these forward-looking statements, which speak only as of the date of this press release. SunCoke does not intend, and expressly disclaims any obligation, to update or alter its forward-looking statements (or associated cautionary language), whether as a result of new information, future events, or otherwise, after the date of this press release except as required by applicable law.
