Vista Oil & Gas announces changes to the capital structure of Aleph Midstream

Mexico City, February 26, 2020 – Vista Oil & Gas, S.A.B. de C.V. (“Vista” or the “Company”) (NYSE: VIST; BMV: VISTA) announced today that its Board of Directors approved changes to the participation of the Company in the capital structure of Aleph Midstream S.A. (“Aleph Midstream”). The Company has reached an agreement with affiliates of Riverstone and Southern Cross Group (the “Financial Sponsors”) to purchase all of the issued and outstanding equity interests of each of the Financial Sponsors in Aleph Midstream, at an aggregate purchase price of $37.5 million (equivalent to the entire equity effectively contributed to Aleph Midstream by the Financial Sponsors).

As a result of such transaction, Aleph Midstream, the first midstream player focused on providing gathering, processing and evacuation services for oil and gas production in the Neuquina Basin, will become a wholly owned subsidiary of Vista, run by a dedicated and experienced management team, with a multi-client approach to pursue the growing business opportunities in the Vaca Muerta play.

Related Party Transaction Disclosure

Along with the acquisition of the equity interests of the Financial Sponsors in Aleph Midstream, the Company will purchase all of the issued and outstanding equity interests of certain officers of Vista, including our Chairman and CEO, Miguel Galuccio, representing approximately 1.4% of the total capital invested, at the same economic terms (an amount equivalent to the entire amount effectively contributed by such officers to Aleph Midstream). Upon closing of the transaction, no officers of Vista will hold a direct participation in Aleph Midstream.

About Vista

Vista is an independent Latin American oil and gas company operating since April 4, 2018. The Company owns high-quality, low-operating cost, high-margin conventional producing assets in Argentina and Mexico, with most of its production and revenues originating in Argentina. In addition, most of its ongoing drilling and workover activities, estimated proved reserves and assets are located in Argentina, including its currently-producing Vaca Muerta wells. Led by an experienced management team, the Company seeks to generate strong returns for its shareholders by leveraging its strong cash flow-producing conventional assets and developing its premier shale acreage in its approximately 134,000 net acres in the Vaca Muerta shale play in Argentina, as well as by increasing the oil recovery factor of the conventional assets it operates in Argentina. In August 2019, Vista became the second largest shale oil producer in the Vaca Muerta play according to the Argentine Secretariat of Energy.
