SUNCOKE ENERGY PARTNERS, L.P. REPORTS

PREDECESSOR FOURTH QUARTER AND FULL YEAR 2012 RESULTS

Lisle, IL (February 5, 2013) – SunCoke Energy Partners, L.P. (NYSE: SXCP) (“SXCP”) today reported predecessor fourth quarter and full year 2012 results.

SXCP is a newly formed master limited partnership (“MLP”) that owns a 65 percent interest in each of SunCoke Energy, Inc.’s (our sponsor) Haverhill and Middletown cokemaking facilities. (See “Initial Public Offering” section below.) These predecessor results are for periods prior to the initial public offering of SXCP and are presented on a combined basis, including the 35 percent interest owned by our sponsor, SunCoke Energy, Inc.

“With the launch of SunCoke Energy Partners, a new publicly-traded master limited partnership, we created a new industry class, coke manufacturing, within the MLP landscape.” said Fritz Henderson, Chairman and Chief Executive Officer of SunCoke Energy Partners, L.P. “We are excited to use the MLP structure to grow our share of the U.S. and Canadian cokemaking market while delivering value to investors over time via expected consistent cash distributions.”

Henderson continued, “Our strong fourth quarter and full year 2012 performance was driven by our new Middletown facility, which began operations in October 2011. The success of the Middletown startup and the sustained solid results at Haverhill this year reflect our continued focus on the disciplined and reliable operation of cokemaking facilities. The strong performance of our Haverhill and Middletown operations combined with our financial flexibility provides a base for SunCoke Energy Partners to pursue growth opportunities in 2013 and beyond.”
