Regency Energy Partners Closes on Acquisition of Midstream Business of Hoover Energy

Expands Portfolio of Services into Crude and Water Gathering

DALLAS, February 3, 2014 – Regency Energy Partners LP (NYSE: RGP) (Regency) announced today that it has closed on its previously announced acquisition of the midstream business of Hoover Energy Partners LP (Hoover) for a combination of cash and Regency common units. Regency issued 4,040,471 Regency common units to Hoover and funded the cash portion of the consideration with borrowings under Regency’s revolving credit facility.

This acquisition further enhances Regency’s geographic footprint in the Delaware Basin in West Texas and expands its suite of producer services by adding crude and water gathering services in one of Regency’s core operating regions. In addition, the Hoover assets are already connected to Regency’s existing Permian Basin rich-gas gathering system which is expected to facilitate a quick integration.

“The Hoover assets are very complementary to Regency’s existing Permian Basin assets, and with the high level of producer activity in the area we believe this acquisition will provide an even stronger, strategic platform on which to further expand our West Texas and New Mexico services through ongoing and proposed organic growth projects,” said Jim Holotik, executive vice president and chief commercial officer of Regency. “The Hoover system includes more than 200,000 acres dedicated to crude oil gathering with existing pipeline takeaway that will expedite Regency’s crude oil gathering expansion plans for the region.”

Hoover’s midstream business include over 800 miles of crude oil, natural gas and water gathering pipelines, two treating plants and a processing plant in Ward, Reeves and Pecos counties in the southern portion of the Delaware Basin. The Perry Ranch Station is a major destination for crude gathered by a customer in the region and is backed by a 20-year dedication. In addition, Hoover’s Delaware Water System is the only open-access water gathering and disposal system in the Delaware Basin.
