As a result of a majority of the outstanding Partnership common units being voted in favor of approval of the Merger Agreement, the Merger Agreement and the transactions contemplated thereby, including the Merger, were approved and adopted.

The Partnership and UGI also announced today that all conditions required to complete the Merger under the terms of the Merger Agreement have been satisfied and all necessary filings will be made for the transaction to take effect on August 21, 2019. The Partnership’s common units will continue to trade on the New York Stock Exchange (“NYSE”) on August 21, 2019 and will be suspended from trading on the NYSE effective as of the opening of trading on August 22, 2019. On or about August 22, 2019, the Partnership will direct the NYSE to file a Form 25 with the Securities and Exchange Commission (“SEC”) to commence the process of delisting the Partnership common units from the NYSE and deregistering such common units under the Securities Exchange Act of 1934, as amended.
