SUNCOKE ENERGY PARTNERS, L.P. ANNOUNCES THIRD QUARTER 2018 RESULTS

Lisle, Ill. (October 25, 2018) - SunCoke Energy Partners, L.P. (NYSE: SXCP) today reported results for the third quarter 2018, which reflect strong throughput volumes at the company’s Convent Marine Terminal and solid performance from Middletown and Haverhill coke facilities, offset by the timing and scope of an outage and unrelated machinery fire at Granite City.

Mike Rippey, President and Chief Executive Officer of SunCoke Energy Partners, L.P. commented, “We continue to be pleased with strong operating performance at CMT as our customers continue to leverage our unique capabilities to capitalize on the attractive export market and our Middletown and Haverhill coke facilities continue to perform in line with our expectations.”

Granite City began a planned outage during the quarter, in which the scope and duration increased materially versus original estimates. Our analysis revealed that additional improvements would benefit the facility and it was prudent to accelerate the timing of this work. Additionally, as discussed on the company’s second quarter earnings call, Granite City experienced a fire on a major piece of equipment which resulted in lost production and lower revenues during the third quarter. The incremental impact of these two events, which was not factored into the company’s full-year guidance, is approximately $9 million. As a result, full year 2018 Adjusted EBITDA attributable to SXCP guidance has been adjusted to range between $210 million to $215 million.

Rippey continued, “While we are disappointed to revise our full-year 2018 guidance as a result of incremental expense and lower revenue at Granite City, our focus has been, and always will be, on driving operational excellence and maximizing long-term performance at our facilities. Based on the expertise we have built across our fleet, it became a clear decision to increase the scope of the work at Granite City in order to improve the long-term reliability and operational performance of those assets.”
