AmeriGas Partners Reports Third Quarter Results, Updates Guidance

VALLEY FORGE, Pa., August 7—AmeriGas Propane, Inc., general partner of AmeriGas Partners, L.P. (NYSE: APU), reported a seasonal net loss attributable to AmeriGas Partners, L.P. for the third fiscal quarter ended June 30, 2012 of $89.4 million compared to a seasonal net loss of $9.2 million for the third quarter of fiscal 2011. The net loss attributable to AmeriGas Partners, L.P. for the current-year period reflects an increased seasonal loss associated with the operations of Heritage Propane, which was acquired in January, the impact of $15.0 million in acquisition and transition expenses related to the Heritage Propane acquisition, and the effects of extraordinarily warmer than normal spring weather. The Partnership’s adjusted earnings before interest expense, income taxes, depreciation and amortization (Adjusted EBITDA) decreased to $16.8 million for the third quarter of 2012 compared to $31.1 million for the same period last year.

For the three months ended June 30, 2012, retail propane volumes sold were 204.0 million gallons compared with retail propane volumes of 155.1 million gallons in the prior-year period. The increase in volumes sold was largely attributable to incremental volumes resulting from the Heritage Propane acquisition (approximately 69 million gallons) partially offset by the impact of the extraordinarily warm spring weather. Weather during the quarter was approximately 24% warmer than normal and 23% warmer than the prior-year period, according to the National Oceanic and Atmospheric Administration.

Revenues for the quarter increased to $571.9 million, reflecting the impact of the Heritage Propane acquisition partially offset by the volume-related decline in revenues associated with the warm spring weather and lower average selling prices associated with lower propane product costs. Total margin increased $67.9 million in the 2012 three-month period, primarily reflecting incremental total margin from the Heritage Propane acquisition partially offset by the impact of the significantly warmer spring weather.

Operating and administrative expenses increased $95.8 million, primarily reflecting incremental Heritage Propane expenses and acquisition and transition expenses of $15.0 million. Partnership operating loss was $48.3 million, compared to operating income of $6.7 million in the prior-year period, as the increase in total margin was more than offset by the increased operating expenses and a $25.0 million increase in depreciation and amortization expenses principally associated with the Heritage Propane acquisition.

Jerry E. Sheridan, chief executive officer of AmeriGas, said, “Our results for the quarter reflect the adverse effects of the very warm spring weather which followed one of the warmest winters on record. Our management team did an excellent job of remaining focused on the day-to-day operations of the business while at the same time making significant progress during the quarter on the Heritage Propane acquisition integration. Our field managers are in place, we have consolidated most of our back office functions, and begun the first phase of field integration efforts to be completed by the end of summer. Given our results thus far, we now expect Adjusted EBITDA for fiscal year 2012 to be in the range of $375 million to $385 million, including the impact of approximately $15 million in net synergies expected to be recognized from the Heritage Propane acquisition during the fourth quarter of fiscal 2012. I am pleased to announce that we are increasing our Adjusted EBITDA forecast for fiscal 2013 to be in the range of $620 million to $660 million, assuming essentially normal weather patterns. Our expectations continue to include the impact of at least $50 million in net synergies expected to be recognized from the Heritage Propane acquisition in fiscal 2013. The change to our fiscal 2013 guidance reflects our current assessment of acquisition integration efforts and business conditions for next year, and underscores our confidence in our ability to continue to achieve significant synergies related to the Heritage acquisition.”

EBITDA, Adjusted EBITDA, and total margin are non-GAAP financial measures. Adjusted EBITDA is defined herein as earnings before interest expense, income taxes, depreciation and amortization, losses on extinguishment of debt and Heritage Propane acquisition and transition expenses. Total margin represents total revenues less total cost of sales. Management believes the presentation of these measures provides useful information to investors to more effectively evaluate the year-over-year results of operations of the Partnership. These measures are not comparable to measures used by other entities and should only be considered in conjunction with net income attributable to AmeriGas Partners, L.P. A reconciliation of EBITDA and Adjusted EBITDA to the most comparable GAAP financial measure is included on the last page of this press release.

Management uses EBITDA to compare year-over-year profitability of the business without regard to capital structure as well as to compare the relative performance of the Partnership to that of other master limited partnerships without regard to their financing methods, capital structure, income taxes or historical cost basis. In view of the omission of interest, income taxes, depreciation and amortization from EBITDA, management also assesses the profitability of the business by comparing net income attributable to AmeriGas Partners, L.P. for the relevant years.

Management also uses EBITDA to assess the Partnership's profitability because its parent, UGI Corporation, uses the Partnership's EBITDA to assess the profitability of the Partnership which is one of UGI Corporation's industry segments. UGI Corporation discloses the Partnership's EBITDA in its disclosure about industry segments as the profitability measure for its domestic propane segment. EBITDA in the three months ended June 30, 2012 includes acquisition and transition expense of $15,037 associated with the Heritage Propane acquisition. EBITDA in the nine months ended June 30, 2012 includes a net pre-tax loss of $13,349 from extinguishment of debt and acquisition and transition expense of $26,892 associated with the Heritage Propane acquisition.
