Vista Oil & Gas S.A.B. de C.V

What it is

Vista Energy is an independent oil and gas producer incorporated in Mexico but overwhelmingly focused on Argentina’s Vaca Muerta formation — one of the largest shale-oil deposits outside North America. Vaca Muerta is recognised as one of the largest shale oil and gas developments outside North America, and Vista has built its entire growth story on top of it.

Vista, which originally listed in Mexico, sold equity in New York in 2019, giving it access to a much larger pool of international investors alongside its Mexican Stock Exchange listing.

Who owns it

Al Mehwar Commercial Investments LLC is the largest individual shareholder, owning roughly 12.82 million shares — about 13.5% of the company. The remaining base is broadly held: institutional shareholders account for about 47% of Vista Energy, with retail investors holding roughly 53%.

Insiders — directors and executives — hold a modest 3.3% of shares per the structured data, and the company has been actively buying back its own stock: as of mid-2025, approximately 1.35 million Series A shares were held in treasury from buybacks carried out by the company.

Who runs it

Miguel M. Galuccio — founder of Vista Energy — has served as Chairman and Chief Executive Officer since July 2017.

He previously served as chairman and CEO of YPF, Argentina’s largest energy company, playing a pivotal role in unlocking Vaca Muerta — earning him the nickname “the architect of Vaca Muerta.”

Pablo Manuel Vera Pinto is co-founder and CFO; Juan Garoby is co-founder and COO; Alejandro Cherñacov is co-founder and heads strategic planning and investor relations. The founding team has stayed intact since the company was created in 2017.

The money, in plain words

Revenue has grown fast: from USD 1.17bn in 2023 to USD 1.65bn in 2024 (+41.0%, our calculation) and USD 2.47bn in 2025 (+50.2%, our calculation). For full-year 2025, output rose 66% to 115,479 barrels of oil equivalent per day, proved reserves jumped 57% to 588 MMboe, and net income grew to USD 719m.

For every dollar of sales, Vista keeps about 26 cents as profit — a net margin of 25.7%, high for a producer operating in an emerging market. For every dollar owners have invested, it earns back roughly 35 cents a year — a return on equity of 35.1%, well above the sector average.

At a price-to-earnings ratio of just under 10×, the market prices it cheaply relative to those returns. The company pays no dividend, preferring to reinvest and buy back shares.

What it is doing now

In April 2025, Vista acquired 100% of Petronas E&P Argentina S.A., which holds a 50% working interest in the La Amarga Chica concession inside Vaca Muerta. The deal was valued at USD 1.2bn, structured as USD 900m in cash, USD 300m in deferred payments, and over 7 million American Depositary Shares.

Then, in early 2026, Vista went further: Vista Energy completed a USD 712m cash-and-stock acquisition of Equinor’s Bandurria Sur and Bajo del Toro interests, adding meaningful Vaca Muerta production. The La Amarga Chica deal alone turned Vista into the largest independent oil producer in Argentina; management has set a target of more than 200,000 barrels of oil equivalent per day by the end of the decade.

What to watch

• Oil price exposure. All material production is in Argentina; every USD 5 move in global oil prices flows almost directly to the bottom line. Vista recorded negative free cash flow in Q3 2025 primarily due to high capital expenditure required for expanding Vaca Muerta operations.
• Argentina risk. Deal flow in Vaca Muerta has picked up considerably under President Javier Milei, who has removed controls that for years held back investment — but a policy reversal would hit Vista hard.
• Debt load. Net leverage stood at 1.5× adjusted EBITDA on a pro-forma basis after the Petronas Argentina transaction. Manageable today, but further acquisitions could stretch it.
• More deals. Vista has been actively seeking shareholder approval to pursue new acquisitions in Vaca Muerta, potentially funded through equity issuance. Watch for announcements on Bandurria Sur integration and the next move.
