The final transaction to complete the proposed combination, the merger of Crestwood Midstream with Inergy Midstream, is expected to occur in the third quarter of 2013. The combination of Crestwood and Inergy will create a fully integrated midstream MLP linking new shale-based energy supplies with growing energy demand across the midstream value chain. The company will have a diverse platform of midstream assets providing broad-ranging services, from gathering and processing to storage and sales, in the premier shale plays in North America, including the Marcellus Shale, Bakken Shale, Eagle Ford Shale, Permian Basin, Powder River Basin, Niobrara Shale, Utica Shale, Barnett Shale, Fayetteville Shale, Granite Wash, Haynesville Shale and Monterey Shale.

Until the completion of the merger, both Crestwood Midstream and Inergy Midstream will continue to operate as separate, independent companies under the leadership of Mr. Phillips. "This is an important first step forward in the process of combining our two companies to create a fully integrated midstream partnership with the size and scale required by our industry to compete for the largest midstream infrastructure projects," Mr. Phillips said. "Together, we will be able to capitalize on new growth opportunities stemming from our ability to offer a more comprehensive and competitive suite of customer services that expand margins and enhance returns on investment. The improved visibility to growth will be a key benefit of the transaction for our investors. With the general partners now consolidated, prior to the merger we will be focusing on an efficient integration of our assets and organizations to leverage our diverse midstream operating platform by providing 'best-in–class' customer services in the premier shale plays across North America."
