The company was listed as a SPAC in Mexico in 2017 and subsequently listed on the NYSE in 2019, after having purchased two companies with a full operating platform in Argentina in 2018.

Vista’s investment thesis is to develop its high-return shale oil drilling inventory of up to 1,150 wells spanning 205,600 Vaca Muerta acres, with focus on cost efficiency and lower carbon intensity production.
