American Midstream Partners, LP (AMID) (“Partnership”) announced today that it closed the acquisition of a minority interest in Delta House from an affiliate of ArcLight Capital Partners, LLC (“ArcLight”), which controls the general partner of the Partnership. The Partnership acquired 25 percent of ArcLight’s 51.7 percent controlling interest in Delta House, a fee-based, semi-submersible floating production system (FPS) and associated oil and gas export pipelines in the deepwater Gulf of Mexico. In addition, as previously announced the Partnership intends to recommend to its board of directors the resumption of annualized distribution increases of approximately five percent, beginning with the distribution for the fourth quarter 2015 payable in February 2016.

The Partnership acquired the interest in Delta House for total consideration of $162 million, which equates to an Adjusted EBITDA multiple of approximately five times for the next twelve months and full-year 2016, and is immediately accretive to the Partnership’s current distribution. The acquisition was funded using a combination of net proceeds from the 7.5 million common unit offering that closed September 15, 2015, and borrowings under the revolving credit facility.

Revolving Credit Facility Upsize

On September 18, 2015, the Partnership executed an amendment to its revolving credit facility to increase borrowing capacity from $500 million to $750 million, with the option to further increase borrowing capacity to $900 million. The Partnership expects to use the credit facility to fund growth and for other Partnership purposes. The syndicate of 17 banks is led by Bank of America, N.A., as Administrative Agent, Collateral Agent, L/C Issuer and Lender. Natixis Bank, BNP, and NBH Capital Finance joined the credit facility as new lenders.

“The drop down of an initial interest in Delta House demonstrates ArcLight’s ongoing strong sponsorship of American Midstream and complements our existing eastern Gulf of Mexico operations to further expand our footprint into the operating core of the Mississippi Canyon, one of the most prolific regions of the Gulf of Mexico,” stated Steve Bergstrom, Executive Chairman, President and Chief Executive Officer. “Delta House is a world-class offshore production handling facility that contributes significant long-term, fee-based cash flows to American Midstream, increasing our fee-based gross margin to greater than 90 percent in 2016. The acquisition is immediately accretive and we intend to recommend the resumption of annualized distribution increases of approximately five percent, beginning with the distribution for the fourth quarter 2015.

“We are executing a multi-year growth plan to drive strong financial metrics in 2016 and beyond, including distribution coverage of approximately 1.2 times, leverage of approximately 4.0, and fee-based gross margin of greater than 90 percent. Importantly, acquiring an interest in Delta House provides significant strength to our balance sheet, and we do not anticipate accessing the equity capital markets for the remainder of 2015 or during 2016 unless industry and macroeconomic conditions improve or to finance accretive acquisitions at the then-current unit price. As we look ahead, we appreciate the support of existing and new lenders in the credit facility, which provides incremental financial flexibility to support near- and long-term growth as we remain focused on executing our growth strategy and delivering long-term, sustainable distribution growth.”

Overview of Delta House

Delta House is operated by LLOG Exploration Offshore, L.L.C. and is located in the Mississippi Canyon region of the deepwater Gulf of Mexico, with nameplate processing capacity of 80,000 barrels of oil per day (Bbl/d) and 200 million cubic feet of gas per day (MMcf/d), and peak processing capacity of 100,000 Bbl/d and 240 MMcf/d, respectively.
