SUNCOKE ENERGY PARTNERS, L.P. INCREASES QUARTERLY CASH DISTRIBUTION NEARLY 6 PERCENT

LISLE, Ill. (April 20, 2015) – The SunCoke Energy Partners, L.P. (NYSE: SXCP) Board of Directors today declared a first quarter 2015 cash distribution of $0.5715 per limited partnership unit payable on May 29, 2015, to unitholders of record on May 15, 2015. The distribution is approximately 6 percent higher than SXCP’s fourth quarter 2014 cash distribution and represents the eighth consecutive quarterly increase. On an annualized basis, the first quarter rate amounts to $2.286 per unit, an increase of 39 percent relative to the $1.65 rate established when SXCP went public in January 2013.

“We started the year projecting a 2 percent increase in cash distributions per unit in each quarter in 2015 and today’s 6 percent increase reflects our confidence in our business model and financial performance,” said Fritz Henderson, Chairman and Chief Executive Officer of SunCoke Energy Partners, L.P. “Since our IPO in January 2013, we have posted consistently solid operating results underpinned by secure, long-term contracts with minimal commodity risk. Given the seasoning of our master limited partnership and track record of performance and distribution growth, we’ve adjusted our targeted cash distribution coverage from 1.15 to 1.10, a level we believe is prudent given our business model and support from our sponsor. On this basis, we expect the annualized distribution rate to improve by $0.08 per unit and we plan to exit 2015 with an annualized distribution rate of $2.42. These increases are supported by the performance of our existing assets and could potentially grow further from future dropdowns and third-party M&A.”
