SUNCOKE ENERGY PARTNERS, L.P. ANNOUNCES FULL-YEAR 2018 RESULTS

AND PROVIDES 2019 GUIDANCE

LISLE, Ill. (February 5, 2019) - SunCoke Energy Partners, L.P. (NYSE: SXCP) (the “Partnership”) today reported fourth quarter and full-year 2018 results, which reflect continued strong throughput volumes at the Partnership’s Convent Marine Terminal (“CMT”) and solid performance from Middletown and Haverhill coke facilities, offset by an extended outage and machinery fire at Granite City.

“While the extended outage at Granite City, which we completed in November, impacted our fourth quarter and full-year 2018 results, we expect this will enhance the long-term reliability and operational performance of these assets,” said Mike Rippey, Chairman, President and Chief Executive Officer of SunCoke Energy Partners, L.P. “The other facilities across the SXCP portfolio continued to deliver strong results in 2018, including handling record volumes at CMT and solid operating performances from our Middletown and Haverhill coke facilities.”

Rippey continued, “As we move forward into 2019, we are focused on delivering operational excellence and the Partnership expects Adjusted EBITDA attributable to SXCP to be between $215 million and $225 million.”

In addition, the Partnership also announced it has entered into a definitive merger agreement with SunCoke Energy, Inc. (NYSE: SXC) whereby SXC will acquire all outstanding common units of SXCP not already owned by SXC in a stock-for-unit exchange transaction (“Simplification Transaction”). Pursuant to the terms of the merger agreement, SXCP unaffiliated common unitholders will receive 1.40 SXC common shares for each SXCP common unit.
