COMBINATION TO DELIVER COMPELLING LONG-TERM VALUE An Important Message for ALL AmeriGas Unitholders A Special Meeting of AmeriGas Unitholders Will be Held on AUGUST 21, 2019. Your Vote is Important to Realizing the Value of the Proposed Combination. Fill Out Your Proxy Card to Vote FOR the Value-Enhancing Combination TODAY.

OVERVIEW OF THE VALUE-ENHANCING COMBINATION On April 2, 2019, AmeriGas Partners, L.P. (NYSE: APU) and UGI Corporation (NYSE: UGI) announced a merger agreement that is expected to be beneficial to the investors of both companies. Under the terms of the agreement, AmeriGas unitholders will receive 0.50 shares of UGI common stock plus $7.63 in cash consideration for each common unit of AmeriGas, representing a premium of 21.9% to AmeriGas’ 30-day(1) volume weighted average price and a 13.5% premium to the April 1, 2019 closing price of $31.13. As part of the transaction, AmeriGas will no longer be a Master Limited Partnership (“MLP”) and will instead become a wholly owned subsidiary of UGI. UGI and AmeriGas have worked together for 60 years, of which, UGI has served as the sole general partner since 1995. UGI currently owns approximately 26% of AmeriGas’ units. After conducting a comprehensive review of strategic alternatives, the Board of Directors of AmeriGas determined that a merger with UGI was the most compelling next step in AmeriGas’ development and the most compelling option for you, as a unitholder. THE BOARD OF AMERIGAS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE UGI AMERIGAS COMBINATION. (1) For the 30-day period ended April 1, 2019

THE COMBINATION WITH UGI IS EXPECTED TO DELIVER SIGNIFICANT NEAR AND LONG TERM BENEFITS TO AMERIGAS UNITHOLDERS, INCLUDING: • An immediate 13.5% premium to the value of your units as of April 1, 2019, the day before the transaction was announced. • Opportunity to share in the value of UGI, which has a diversified asset portfolio and a history of meeting long-term commitments to shareholders including 6% - 10% annual earnings growth and 4% annual dividend growth. • A financially stronger AmeriGas with an improved cost of capital, lower debt and significantly enhanced credit profile – all vital ingredients for sustained growth and stability. • More efficiencies resulting from dissolution of administratively complex MLP structure, which also resolves distribution coverage challenges. • A 15% increase – or $200 million – in cash flow per share for fiscal 2020, which will be used to grow the UGI business with diversified investments across all segments. • Continued EPS and dividend growth driven by cash engine of combined company. TO REALIZE THESE BENEFITS, AMERIGAS UNITHOLDERS MUST VOTE IN FAVOR OF THE PROPOSED COMBINATION. You can choose to vote by telephone, Internet, or by mail by following the easy instructions on the enclosed proxy card.
