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

Earlier today, everyone should have received communications from John Walsh regarding a transaction that will consolidate the ownership of AmeriGas Partners, L.P. by UGI Corporation. As John mentioned in his memo, this change is focused on positioning AmeriGas for continued success and profitable growth today, and into the future.

One of the themes we have emphasized since I became CEO last September is the need for our teams to embrace change as we seek to position the company for success. This transaction is an example of a significant change that will be truly beneficial for AmeriGas. While UGI’s percentage ownership of AmeriGas will change, I want to emphasize that, for the vast majority of AmeriGas employees, there will be no impact on your day-to-day responsibilities. Most importantly, it will not affect the work we do, and I know that you will continue to provide excellent service, day in and day out, to our customers.

To the extent possible, we will keep you informed of the progress of the transaction through our customary communications channels (AmeriGas World, Thinktime, direct-email to the leadership team) to address any questions or concerns that may arise.

In closing, I personally want to thank each of you for your continuing hard work and commitment to the company, our customers, and the communities in which we operate.
