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 900 wells spanning 183,100 Vaca Muerta acres, with focus on cost efficiency and low carbon intensity production.

Since 2018, Vista ignited a strong growth trajectory, showing solid production results to date. By December 2022, the company had tied-in 68 wells in Vaca Muerta delivering best-in-basin productivity, proving the top-quality of its acreage and its growth capabilities.
