2026 1st Quarter Results Mexico City, April 29, 2026 NYSE: VIST BMV: VISTA

![LOGO](g93526dsp5.jpg)

**April 29, 2026, Mexico City, Mexico** 

Vista Energy, S.A.B. de C.V. ("Vista" or the "Company") (NYSE: VIST; BMV: VISTA) reported today its financial and operational results corresponding to Q1 2026.

The Company will present its Q1 2026 results through a webcast on Thursday, April 30, 2026, at 9:00 am Mexico City time (11:00 am ET; 12:00 pm BAT). At such event, Vista will also present an updated 2026 guidance.

**Q1 2026 highlights:** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total production in Q1 2026 was 134,741 boe/d, a 67% increase compared to Q1 2025, mainly driven by the
acquisition of 50% working interest in La Amarga Chica block in April 2025 and organic growth. Total production in Q1 2026 was almost flat compared to Q4 2025. Oil production in Q1 2026 was 116,655 bbl/d, a 68% increase y-o-y.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In Q1 2026, average realized crude oil price was 60.1 $/bbl, a 2% increase compared to Q4 2025, and a 12%
decrease compared to Q1 2025, in both cases driven by changes in Brent crude oil. <sup>(1)</sup>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Realized natural gas price for Q1 2026 was 2.0 $/MMBtu, a 21% decrease y-o-y, mainly driven by higher volumes sold to the industrial sector at an average price of 1.4 $/MMBtu during the quarter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total revenues in Q1 2026 were 694.3 $MM, 58% above Q1 2025, mainly driven by oil production growth. Total
revenues were 1% above Q4 2025, as slightly higher oil prices were partially offset by a 1% decrease in oil production. Total net revenues during the quarter were 670.6 $MM. Net oil revenues from sales at export parity prices, combining both
international and domestic markets, were 100% of total net oil revenues. Net revenues from oil and gas exports were 431.0 $MM, representing 64% of total net revenues. <sup>(1)</sup>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Lifting cost in Q1 2026 was 4.3 $/boe, 8% below Q1 2025, driven by the dilution of fixed costs due to production
growth and the focus on cost control.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Selling expenses in Q1 2026 were 3.8 $/boe, a 41% decrease y-o-y, driven by the elimination of trucking as of the end of Q1 2025, as the Oldelval Duplicar pipeline became online. <sup>(2)</sup>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA for Q1 2026 was 450.8 $MM, a 64% increase y-o-y, mainly driven by 67% production growth, which offset lower realized oil prices. Adjusted EBITDA margin was 65%, 3 p.p. above Q1 2025, as lower export duties, selling expenses and lifting cost on a per
boe basis offset lower realized oil prices. <sup>(2)</sup>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net income in Q1 2026 was 107.7 $MM, compared to 82.8 $MM in Q1 2025, reflecting a higher Profit before income
tax and a lower Income tax expense. Adjusted net income during Q1 2026 totaled 93.0 $MM, compared to 75.9 $MM in Q1 2025. EPS was 1.0 $/share in Q1 2026, compared to 0.9 $/share in Q1 2025. Adjusted EPS was 0.9 $/share in Q1 2026, compared to 0.8
$/share in Q1 2025.

![LOGO](g93526dsp5.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Capex during Q1 2026 was 391.2 $MM. The Company invested 335.6 $MM in drilling, completion and workover of Vaca
Muerta wells, mainly in connection with the drilling of 19 net wells, the completion of 25 net wells and the tie-in of 23 net new wells during the quarter. Additionally, the Company invested 26.7 $MM in
development facilities, and 28.9 $MM in G&G studies, IT and other projects.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In Q1 2026, the Company recorded a free cash flow of -341.4 $MM. Free
cash flow was -10.1 $MM adjusted by non-recurring items (working capital from VEISA operations, income tax payment in Mexico and payments related to the Equinor Transaction, as explained below).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cash flow generated by operating activities was 85.7 $MM, reflecting an increase in working capital of 248.2 $MM
and income tax payments of 61.4 $MM. These effects were mainly driven by two non-recurring items: 205.6 $MM of working capital related to the initiation of operations of VEISA and 46.0 $MM corresponding to an
income tax payment in Mexico.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cash flow used in investing activities reached 427.1 $MM for the quarter, reflecting accrued capex of 391.2 $MM,
payments related to the Equinor Transaction of 79.7 $MM and a decrease in capex-related working capital of 53.0 $MM.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cash flow from financing activities totaled 418.1 $MM, mainly driven by proceeds from borrowings of 589.5 $MM,
partially offset by the repayment of borrowings' principal of 129.5 $MM and the payment of borrowings' interests for 26.9 $MM. <sup>(3)</sup>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Revenues as filed and reported were 865 $MM in Q1 2026 and 719 $MM in Q4 2025. For comparison purposes, revenues
and avg. realized oil prices are net of Commodity risk management contracts and Sea freight selling expenses. Commodity risk management contracts were -150.7 $MM in Q1 2026. Sea freight selling expenses were
20.0 $MM in Q1 2026 and 29.8 $MM in Q4 2025, which were collected as revenues and incurred by our trading subsidiary VEISA.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Selling expenses as filed and reported were 66.2 $MM in Q1 2026 and 81.8 $MM in Q4 2025. For comparison
purposes, Selling expenses are net of 20.0 $MM of Sea freight selling expenses incurred by our trading subsidiary VEISA in Q1 2026, equivalent to 1.6 $/boe, which were also collected as revenues, and 29.8 $MM equivalent to 2.4 $/boe in Q4 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Q1 2026 Cash flow from financing activities is the sum of: (i) cash flow generated by financing activities
for 409.1 $MM; (ii) effect of exposure to changes in the foreign currency rate and other financial results of cash and cash equivalents for -7.6 $MM; (iii) the variation in Argentine government bonds
for -0.6 $MM; and (iv) Other investments for 17.3 $MM.

Although VEISA sells mostly on a CIF (Cost, Insurance and Freight), CFR (Cost and Freight) or DAP (Delivered At Place) basis, for consistency purposes we will continue to report sales and realized prices on a FOB (Free On Board) equivalent basis.

During Q1 2026, total revenues as filed and reported were 865.0 $MM. Net of the effect of Commodity risk management contracts and Sea freight selling expenses, total revenues were 694.3 $MM, 58% above Q1 2025, mainly driven by oil production growth. Total revenues were 1% above Q4 2025, as slightly higher oil prices were partially offset by a 1% decrease in total production. Total net revenues were 670.6 $MM. Net revenues from oil and gas exports were 431.0 $MM, representing 64% of total net revenues.

Crude oil net revenues in Q1 2026 totaled 650.8 $MM, representing 97.0% of total net revenues and a 61% increase compared to Q1 2025, driven by oil production growth and partially offset by lower realized oil prices. Average realized oil price during the quarter was 60.1 $/bbl, 12% below Q1 2025 and 2% above Q4 2025, mainly driven by changes in Brent oil prices. Net oil revenues from sales at export parity prices, combining both international and domestic markets, were 100% of total net oil revenues.

During Q1 2026, the Company exported 67% of crude oil sales volumes. Net revenues from the oil export market accounted for 66% of net oil revenues, reaching 428.5 $MM.

Natural gas net revenues in Q1 2026 were 18.2 $MM, representing 2.7% of total net revenues. The average realized natural gas price for the quarter was 2.0 $/MMBtu, a 21% decrease compared to Q1 2025. Plan GasAr represented 36% of total natural gas sales volume, with an average realized price of 2.5 $/MMBtu during the quarter. Sales to industrial clients represented 57% of total natural gas sales volume at an average realized price of 1.4 $/MMBtu. The remaining 7% of total natural gas sales volume was exported at an average realized price of 4.1 $/MMBtu.

NGL net revenues were 1.6 $MM during Q1 2026, representing 0.2% of total net revenues. NGL average price was 324 $/tn.

---

Adjusted EBITDA was 450.8 $MM in Q1 2026, a 64% increase compared to 275.4 $MM in Q1 2025, mainly driven by a 67% production increase, combining the consolidation of 50% working interest in La Amarga Chica and organic growth. On a sequential basis, Adjusted EBITDA increased 2% in Q1 2026, driven by slightly higher realized oil prices.

Adjusted EBITDA margin was 65%, 3 p.p. above Q1 2025, as lower export duties, lifting cost and selling expenses on a per boe basis offset lower realized oil prices. <sup>(3)</sup>

(1) Adj. EBITDA = Profit for the period, net + Income tax (expense) / benefit + Financial income (expense), net +
Depreciation, depletion and amortization + Income (loss) from investments in associates + Impairment of long-lived assets + Gain from business combination + Gain from asset disposals + Restructuring expenses + Gain related to the transfer of
conventional assets + Other non-cash costs related to the transfer of conventional assets

(2) Adj. EBITDA Margin = Adj. EBITDA / (Total Revenues + Gain from Exports Increase Program – Sea freight
selling expenses + Commodity risk management contracts). Gain from Exports Increase Program is zero as of Q2 2025. Adj. EBITDA Margin for Q1 2026 (65%) = Adj. EBITDA (450.8 $MM) / (Total Revenues (865.0 $MM) + Gain from Exports Increase Program (0.0
$MM) – Sea freight selling expenses (20.0 $MM) + Commodity risk management contracts (-150.7 $MM)).

(3) Selling expenses as filed and reported were 66.2 $MM in Q1 2026 and 81.8 $MM in Q4 2025. For comparison
purposes, Selling expenses are net of 20.0 $MM of Sea freight selling expenses incurred by our trading subsidiary VEISA in Q1 2026, equivalent to 1.6 $/boe, which were also collected as revenues, and 29.8 $MM equivalent to 2.4 $/boe in Q4 2025.
