NGL Energy Partners LP (NYSE: NGL) announced today the completion of the previously announced contribution to the Partnership of all of the assets comprising the propane operations of E. Osterman Propane, Inc. and its affiliated companies for a combination of cash (subject to a customary working capital payment) and 4,000,000 common units. In connection with the closing of the transaction, Vincent J. Osterman has joined the Board of Directors of the Partnership’s general partner, NGL Energy Holdings LLC. “This completes a transaction which expands the Partnership’s retail propane footprint into the Northeast, adding geographic balance to our assets and reduces the impact of weather patterns in any one region of the U.S.,” said H. Michael Krimbill, the Chief Executive Officer of the Partnership. “This transaction nearly doubles the size of the Partnership. In addition, the Partnership’s equity is increased by approximately $84 million dollars at a common unit price of $21.00.” The assets contributed by Osterman consist of retail operations in Massachusetts, Connecticut, Maine, New Hampshire, New York, Rhode Island and Vermont. They comprise 20 owned or leased customer service and satellite distribution locations, with aggregate propane storage capacity of 1.7 million gallons. In the twelve month period ended May 31, 2011, Osterman sold over 40 million gallons of propane to a mix of approximately 80,000 residential, commercial, industrial and agricultural customers.
