On December 20, 2013, Summit Midstream Partners, LLC (“Summit Investments”), the privately held company that owns and controls the general partner of Summit Midstream Partners, LP (the “Partnership”), issued a press release announcing that it had executed a definitive agreement with Blackhawk Midstream, LLC (“Blackhawk”) to acquire (the “Acquisition”) Blackhawk’s equity interest in two entities, Ohio Gathering Company, L.L.C. and Ohio Condensate Company, L.L.C. (collectively, “Ohio Gathering Company”). At the appropriate time, and subject to certain factors discussed in the press release, Summit Investments intends to offer the Partnership all or a portion of Summit Investments’ equity interests in Ohio Gathering Company.

Copies of the press release and a slide presentation providing supplemental information with respect to the Acquisition are furnished hereto as Exhibits 99.1 and 99.2, respectively.

In accordance with General Instruction B.2 of Form 8-K, the press release and slide presentation are deemed to be “furnished” and shall not be deemed “filed” for the purpose of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall such information and Exhibit be deemed incorporated by reference into any filing under the Securities Act or the Securities Exchange Act of 1934, each as amended.
