SUNCOKE ENERGY PARTNERS, L.P. TO

ACQUIRE KANAWHA RIVER TERMINALS LLC

Lisle, IL (August 6, 2013) – SunCoke Energy Partners, L.P. (NYSE: SXCP) today announced that its wholly-owned subsidiary executed a definitive agreement to acquire 100 percent of the ownership interest in Kanawha River Terminals LLC (“KRT”) for $86 million. KRT is wholly-owned by Traxys North America LLC, an international financing, marketing, distribution and trading company in metals, minerals and mining industries. This transaction is subject to regulatory approval and customary closing conditions and is expected to close in fourth quarter 2013. SXCP plans to finance this acquisition with a combination of available cash and its existing revolving credit facility.

KRT is a leading metallurgical and thermal coal blending/handling terminal service provider with the collective capacity to blend and transload more than 30 million tons of coal annually. KRT owns four coal handling facilities, the largest of which is the Ceredo Terminal located on the Ohio River in West Virginia. This strategically located terminal has both inbound and outbound rail logistics provided by CSX and Norfolk Southern and the capability to offload and load barges. As a result, the Ceredo terminal is able to serve both domestic and international export markets. KRT’s other coal handling facilities are located on the Big Sandy and Kanawha Rivers, as well as on Kentucky Highway 1185 near Louisa, Kentucky. In addition, KRT owns an idled liquids terminal on the Ohio River that has more than four million gallons of liquid storage capacity. With its strategic river locations and convenient access to highways and railroads, KRT can deliver products to all U.S. ports on the Gulf Coast, East Coast and Great Lakes.

“KRT is an excellent strategic fit with SXCP and advances our position in coal logistics,” said Fritz Henderson, Chairman and Chief Executive Officer of SXCP. “With this acquisition, we further integrate our cokemaking business with coal handling operations that currently support our Middletown and Granite City cokemaking facilities. We also will broaden our customer base to serve companies in the coal, steel and public utility industries. We anticipate KRT’s operations will be immediately accretive and contribute to future earnings and distributable cash flow growth.”

In 2013, KRT is projected to handle approximately 15 million tons of coal, 56 percent of which is anticipated to be metallurgical coal. Based on our preliminary outlook and anticipated financing plan, KRTs operations are expected to be accretive to SXCP’s distributable cash flow by approximately $6 million, or $0.18 per common unit, on an annualized basis. Assuming a targeted 50/50 debt-to-equity capital structure for SXCP, the annualized accretion per common unit would be approximately $0.11. This contribution is in addition to the anticipated increase in distributable cash flow from SXCP’s previously announced acquisition of Lakeshore Coal Handling Corporation, expected to close later in the third quarter. SXCP plans to update its guidance for both the KRT and Lakeshore Coal Handling Corporation acquisitions in the fourth quarter.
