Filed by UGI Corporation

Pursuant to Rule 425 Under the Securities Act of 1933

And Deemed Filed Pursuant to Rule 14a-12

Under the Securities Exchange Act of 1934

Subject Company: AmeriGas Partners, L.P.

Commission File No. 001-13692

Date: April 2, 2019

This morning, we announced that UGI Corporation has entered into an agreement to acquire the outstanding common units of AmeriGas that UGI does not already own. UGI currently owns 26% of AmeriGas and has served, through a subsidiary, as its sole General Partner since 1995. UGI’s history with AmeriGas dates back to 1959, when we entered the propane distribution business. Upon completion of the transaction, which is expected to close later this year, AmeriGas will once again become a 100% owned subsidiary of UGI—similar to the other business units in the UGI Family of Companies.

This transaction follows a comprehensive review of AmeriGas’ strategic alternatives, and is the most logical, compelling, and natural next step in our close relationship with AmeriGas. Importantly, upon closing, this transaction will immediately make us a stronger company—both financially and operationally—and will serve the organization’s best interests.

Among the notable benefits of this strategic investment, UGI will have significant additional capital to invest across our business segments. We also will have the opportunity to further align AmeriGas with UGI’s international LPG distribution operations to drive efficiencies, support strategic initiatives, and accelerate growth. AmeriGas, in turn, will have a stronger balance sheet that it can put to use to support growth in such initiatives as the national accounts and cylinder exchange programs and its best-in-class technology platforms, which have dramatically improved the customer experience. I know you join me in viewing the transaction as beneficial for both organizations and for our respective stakeholders as it accelerates our business strategy.

While today’s announcement is a great development for UGI’s future profitable growth, I want you to know this change should not affect our day-to-day activities, and I would ask all of you to remain focused on the contributions you bring to your roles at UGI and at AmeriGas. Most critically, it is important that we continue our commitment to the safe and reliable delivery of energy to our customers and to the many communities we serve, as well as our commitment to the safety of our colleagues.

Looking ahead, we have a dedicated team working on completing the transaction. We expect the transaction to close later this year, subject to approval by the AmeriGas unitholders. With our long history with AmeriGas, as well as our deep knowledge and understanding of its business strategy, finances, position in the marketplace and especially its experienced and committed employee base, I am confident there will be a smooth path to the closing and beyond.

In closing, I want to thank you all for the work you do, and for your dedication to our organization. Your efforts are the critical driver of our success, and the reason we will continue to deliver on our mission to be a leader in the distribution of safe, reliable, and affordable energy. I look forward to providing you with updates on our progress.
