AmeriGas Partners Reports Significant Increase in First Quarter Earnings

VALLEY FORGE, Pa., January 31—AmeriGas Propane, Inc., general partner of AmeriGas Partners, L.P. (NYSE: APU), reported net income attributable to AmeriGas Partners for the first quarter of fiscal 2013 ended December 31, 2012 of $96.7 million compared to $42.5 million for the same period last year. Net income attributable to AmeriGas Partners for the current-year period reflects increased earnings associated with the operations of Heritage Propane, which was acquired in January 2012. The Partnership’s adjusted earnings before interest expense, income taxes, depreciation and amortization (Adjusted EBITDA) increased to $193.3 million for the first quarter of 2013 compared to $87.4 million for the same period last year reflecting the impact of the Heritage Propane acquisition.

Retail volumes sold reflect incremental sales associated with the operations of Heritage Propane partially offset by the impact of significantly warmer than normal weather. For the three months ended December 31, 2012, retail propane volumes sold were 350.7 million gallons compared with retail propane volumes of 220.9 million gallons in the prior-year period. Weather for the quarter was 9.0% warmer than normal, but 3.4% colder than in the prior-year period, according to the National Oceanic and Atmospheric Administration (“NOAA”). Weather for the month of December was 13.1% warmer than normal and 1.5% warmer than last year, according to NOAA.

Jerry E. Sheridan, chief executive officer of AmeriGas, said, “Despite promising weather during much of October and into November, the peak heating season got off to a slow start during December, when we experienced weather that was significantly warmer than normal and even slightly warmer than December 2011. Despite the short-term challenges brought about by these uneven weather patterns, our management team remains focused on providing excellent customer service and delivering the significant benefits of the Heritage Propane acquisition. We are on track to recognize $60 million in synergies when the integration is completed later this year and we are confident that, given a return to more normal weather, we will more fully demonstrate the true earnings power of the New AmeriGas. Given our results thus far and assuming essentially normal weather for the remainder of the year, we now anticipate Adjusted EBITDA for fiscal 2013 to be in the range of $620 million to $645 million.”

Revenues for the quarter increased to $876.6 million from $683.8 million in the prior-year period, reflecting the higher retail volumes sold partially offset by lower average selling prices. The average wholesale cost of propane at Mont Belvieu, Texas, for the current quarter was approximately 38% lower than the average cost in the same period last year. Total margin increased $184.6 million due to higher volumes sold, higher average retail unit margins and increased total margin related to ancillary sales and services.

Operating and administrative expenses increased $83.6 million primarily reflecting incremental expenses associated with the operations of Heritage Propane. Acquisition and transition expenses associated with Heritage Propane were $5.5 million in the current-year period compared to $3.7 million in the prior-year period. Operating income increased $79.8 million primarily reflecting the higher total margin partially offset by the increased operating expenses and greater depreciation and amortization expenses ($25.2 million) principally associated with Heritage Propane.

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, 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 reportable segments. UGI Corporation discloses the Partnership’s EBITDA in its disclosure about reportable segments as the profitability measure for its domestic propane segment. EBITDA in the three months ended December 31, 2012 and 2011 includes acquisition and transition expense of $5,488 and $3,717, respectively, associated with the Heritage Propane acquisition. EBITDA in the twelve months ended December 31, 2012 includes a pre-tax loss of $13,349 from extinguishments of debt and acquisition and transition expense of $47,958 associated with the Heritage Propane acquisition. EBITDA in the twelve months ended December 31, 2011 includes a pre-tax loss of $38,117 from extinguishments of debt and acquisition-related expense of $3,717 associated with the Heritage Propane acquisition.
