1.2 Significant transactions for the year

1.2.1 Agreement signed with Petrolera Aconcagua Energía S.A. (“Aconcagua”) related to conventional assets (“transfer of conventionalassets”)

On February 23, 2023, the Company approved the agreement signed by its subsidiary Vista Energy Argentina S.A.U. (“Vista Argentina”) with Aconcagua for the operations in the following concessions of the Neuquina Basin, Argentina (the “Transaction”): (i) the Entre Lomas upstream concession located in the Province of Neuquén; (ii) Entre Lomas, Jarilla Quemada, Charco del Palenque, Jagüel de los Machos and 25 de Mayo-Medanito S.E upstream concessions located in the Province of Río Negro (jointly, the “Exploitation Concessions”); (iii) the Entre Lomas and Jarilla Quemada gas transportation concession located in the Province of Río Negro, and (iv) the 25 de Mayo-Medanito S.E. crude oil transportation concession located in the Province of Río Negro (jointly with the Exploitation concessions the “Concessions”).

Notes to the unaudited interim condensed consolidated financial statements as of December 31, 2023 and 2022, and for the years and for the three-monthperiods ended December 31, 2023 and 2022

(Amounts expressed in thousands of US Dollars, except otherwise indicated)

The Concession transaction is governed by a joint operating agreement between both parties. Among other issues, it is established that Vista Argentina maintains the right to explore and develop the Vaca Muerta formation in the Exploitation Concessions, and that it may obtain one or more independent and separate unconventional concessions to develop such resources.

In addition, the Parties signed natural gas processing and sales agreements whereby Aconcagua undertakes to provide Vista Argentina with certain additional volumes of natural gas, and to process and deliver the natural gas applicable to Vista Argentina.

Note 2. Basis of preparation and material accounting policies

2.1 Bases of preparation and presentation

The unaudited interim condensed consolidated financial statements as of December 31, 2023 and 2022, and for the years and for the three-month periods ended December 31, 2023 and 2022 were prepared in accordance with the International Accounting Standard (“IAS”) 34 – “Interim Financial Reporting”, issued by the International Accounting Standards Board (“IASB”).

2.4 Summary of material accounting policies

2.4.1 Impairment testing of goodwill and nonfinancial assets other than goodwill

Nonfinancial assets, including identifiable intangible assets, are tested for impairment at the lowest level in which there are separately identifiable cash flows largely independent of the cash flows of other groups of assets or Cash Generating Units (“CGUs”).

In Argentina, oil and gas properties were grouped as detailed bellow:

•	As of December 31, 2023, (i) operated exploitation concessions of unconventional oil and gas exploration and<br>production; and (ii) non-operating concessions of conventional oil and gas exploration and production.
•	As of December 31, 2022, (i) operated exploitation concessions of conventional oil and gas exploration and<br>production; (ii) operated concessions of unconventional oil and gas exploration and production; and (iii) non-operating concessions of conventional oil and gas exploration and production.<br>
---	---

The Company also identified only 1 (one) CGUs in Mexico: (i) operated exploitation concessions of conventional oil and gas exploration and production, as of December 31, 2023 and 2022.

The Company conducts its impairment test of nonfinancial assets when there is an indication that the carrying amount may be impaired. Moreover, Goodwill is tested every December. The Company bases the impairment test on the calculation of value in use and reviews the relationship between the recoverable amount and the carrying amount of its assets.

As of December 31, 2023, the Company identified impairment indicators, mainly resulting from the decline in the international price of crude oil in Mexico and local price of natural gas in Argentina. Therefore, the Company performed an impairment testing; using estimated cash flows per CGU, to determine the recoverable amount of the long -lived assets and compare it against carrying amount of CGU.

As result of the analysis performed, for the year ended December 31, 2023 the Company recorded an impairment of 22,906 related to the CGU operated exploitation concessions of conventional oil and gas exploration and production in Mexico and 1,679 related to the CGU for non-operating exploitation concessions of conventional oil and gas exploration and production in Argentina.

As of December 31, 2022, the Company did not identify indications of impairment related with goodwill and nonfinancial assets other than goodwill.

Main assumptions used

The Company’s calculation of the value in use related to the aforementioned CGUs is more sensitive to the following assumptions:

						As of December 31, 2022
			Mexico			Argentina			Mexico
Discount rates (after taxes)	12.9	%		6.0	%		11.9	%		7.9	%
Discount rates (before taxes)	21.9	%		8.2	%		18.7	%		11.6	%
Prices of crude oil, natural gas and Liquefied Petroleum Gas (“LPG”)
Crude oil (/bbl) (1)

(Amounts expressed in thousands of US Dollars, except otherwise indicated)

Sensitivity to changes in assumptions

Regarding the assessment of the value in use as of December 31, 2023, and 2022, the Company considers that there are no reasonably possible changes in any of the abovementioned main assumptions that may cause the carrying amount of any CGU to significantly exceed its recoverable amount, except for the following:

	As of December 31, 2023		As of December 31, 2022
	Argentina ^(1)^	México	Argentina ^(2)^	México
Discount rate	+/- 10%		+/- 10%
Carrying amount	(136) / -	(2,559) / -	- / -	- / -
Expected prices of crude oil, natural gas and LPG	+/- 10%		+/- 10%
Carrying amount	- / (349)	- / (13,402)	- / (41,816)	- / -
^(1)^	Related to the non-operating concessions of conventional oil and gas<br>exploration and production CGU.
---	---
^(2)^	Related to the operated concessions of conventional oil and gas exploration and production CGU.<br>
---	---

The aforementioned sensitivity analysis may not be representative of the actual change in the carrying amount because it is unlikely that the change in the assumptions would occur in isolation, as some assumptions may be correlated.

As of December 31, 2023, and 2022, the net carrying amount of property, plant and equipment, intangible assets and right-of-use assets is disclosed in Notes 12, 13 and 14, respectively.

Note 3. Segment information

The Chief Operating Decision Maker (the “Committee” or “CODM”) is in charge of allocating resources and assessing the performance of the operating segment. It supervises operating profit (loss) and the performance of the indicators related to its oil and gas properties on an aggregate basis to make decisions regarding the location of resources, negotiate with international suppliers and determine the method for managing contracts with customers.

The CODM considers as a single segment the exploration and production of crude oil, natural gas and LPG (including Exploration and Production commercial activities), through its own activities, subsidiaries and interests in joint operations and based on the nature of the business, customer portfolio and risks involved. The Company aggregated no segment as it has only one.

(Amounts expressed in thousands of US Dollars, except otherwise indicated)

b) Diluted

Diluted earnings per share is calculated by dividing the Company’s profit by the weighted average number of ordinary shares outstanding during the year / period, plus the weighted average of dilutive potential ordinary shares.

Potential ordinary shares will be considered dilutive when their conversion to ordinary shares may reduce earnings per share or increase losses per share. They will be considered antidilutive when their conversion to ordinary shares may result in an increase in earnings per share or a reduction in loss per share.

The calculation of diluted earnings per share does not involve a conversion; the exercise or other issue of shares that may have an antidilutive effect on loss per share, or when the exercise price is higher than the average price of ordinary shares during the year / period, no dilution effect is booked, as diluted earnings per share is equal to basic earnings per share.

---	---

As of December 31, 2023, the Company holds 3,705,757 Series A shares to be used in the Long-Term Incentive Plan (“LTIP”), that, on the date of this unaudited interim condensed consolidated financial statements, are currently unvested. Consequently, they are not included in the weighted average number of ordinary shares to calculate diluted earnings per share.

Due to the short-term nature of current trade and other receivables, it carrying amount is considered similar to its fair value. The fair values of noncurrent trade and other receivables do not differ significantly from it carrying amounts either.

As of December 31, 2023, in general, accounts receivable has a 19-day term for sales of crude oil and a 50-day term for sales of natural gas and LPG.

The Company sets up a provision for trade receivables when there is information showing that the debtor is facing severe financial difficulties and that there is no realistic probability of recovery, for example, when the debtor goes into liquidation or files for bankruptcy proceedings. Trade receivables that are derecognized are not subject to compliance activities. The Company recognized an allowance for expected credit losses of 100% against all trade receivables that are 90 days past due because based on its history these receivables are generally not recovered.

As of December 31, 2023 and 2022 an allowance for expected credit losses was recorded in trade and other receivables for 52 and 231 respectively.

As of the date of these interim condensed consolidated financial statements, maximum exposure to credit risk is related to the carrying amount of each class of accounts receivable.

17.4 Fair value

This note includes information on the Company’s method for assessing the fair value of its financial assets and liabilities.

17.4.1 Fair value of theCompany’s financial assets and liabilities measured at fair value on a recurring basis

The Company classifies the measurements at fair value of financial instruments using a fair value hierarchy, which shows the relevance of the variables applied to carry out these measurements. The fair value hierarchy has the following levels:

•	Level 1: quoted (unadjusted) prices in active markets for identical assets or liabilities.<br>
•	Level 2: data other than the quoted prices included in Level 1 that are observable for assets or<br>liabilities, either directly (that is prices) or indirectly (that is derived from prices).
---	---
•	Level 3: data on the asset or liability that are based on information that cannot be observed in the market<br>(that is, non-observable data).
---	---

The following chart shows the Company’s financial assets measured at fair value as of December 31, 2023 and 2022:

As of December 31, 2023	Level 1		Level 2		Level 3		Total
Assets
Financial assets at fair value through profit or loss

Notes to the unaudited interim condensed consolidated financial statements as of December 31, 2023 and 2022, and for the years and for the three-monthperiods ended December 31, 2023 and 2022

(Amounts expressed in thousands of US Dollars, except otherwise indicated)

The value of financial instruments traded in active markets is based on quoted market prices as of the date of these accompanying unaudited interim condensed consolidated financial statements. A market is considered active when quoted prices are available regularly through a stock exchange, a broker, a specific sector entity or regulatory agency, and these prices reflect regular and current market transactions between parties at arm’s length. The quoted market price used for financial assets held by the Company is the current offer price. These instruments are included in Level 1.

For financial instruments not traded in an active market, the fair value is determined using appropriate valuation techniques. These valuation techniques maximize the use of observable market data, when available, and minimize the use of Company’s specific estimates. Should all significant variables used to establish the fair value of a financial instrument be observable, the instrument is included in Level 2.

Should one or more variables used in determining the fair value not be observable in the market, the financial instrument is included in Level 3.

There were no transfers between Level 1 and Level 2 from December 31, 2022, through December 31, 2023.

17.4.2 Fair value of financial assets and liabilities that are not measured at fair value (but require fair value disclosures)

Except for the information included in the following chart, the Company considers that the carrying amounts of financial assets and liabilities recognized in the interim condensed consolidated financial statements approximate to its fair values, as explained in the related notes.

As of December 31, 2023	Carrying amount		Fair value		Level
Liabilities
Borrowings		616,055		516,699	****	2
Total liabilities	****	616,055	****	516,699

17.5 Risk management objectives and policies concerning financial instruments

17.5.1 Financial risk factors

The Company’s activities are exposed to several financial risks: market risk (including exchange rate risk, interest rate risk and price risk), credit risk and liquidity risk.

Financial risk management is included in the Company’s global policies, and it adopts a comprehensive risk management policy focused on tracking risks affecting the entire Company. This strategy aims at striking a balance between profitability targets and risk exposure levels. Financial risks are derived from the financial instruments to which the Company is exposed during period-end or as of every period-end.

The Company’s financial department, controls financial risk by identifying, assessing and covering financial risks. The risk management systems and policies are reviewed regularly to show the changes in market conditions and the Company’s activities.

The Company reviewed its exposure to financial risk factors and identified no significant changes in the risk analysis included in its annual consolidated financial statements as of December 31, 2022, except for the following:

17.5.1.1 Market risk

Exchange rate risk

The Company’s financial position and results of operations are sensitive to exchange rate changes between USD and ARS. As of December 31, 2023 and 2022, the Company performed foreign exchange currency hedge transactions, and the impact in the results of the year is recognized in “Other financial income (expense)”.

Most Company sales are denominated in USD, or the changes in sales follow the changes in USD listed price.

VISTA ENERGY, S.A.B. DE C.V.

Notes to the unaudited interim condensed consolidated financial statements as of December 31, 2023 and 2022, and for the years and for the three-monthperiods ended December 31, 2023 and 2022

(Amounts expressed in thousands of US Dollars, except otherwise indicated)

During the years ended December 31, 2023 and 2022, ARS depreciated by about 356% and 72%, respectively.

The following chart shows the sensitivity to a modification in the exchange rate of ARS to USD while maintaining the remainder variables constant. Impact on profit before taxes is related to changes in the fair value of monetary assets and liabilities denominated in currencies other than the USD, the Company’s functional currency. The Company’s exposure to changes in foreign exchange rates for the remainder currencies is immaterial.

	As ofDecember 31,2023
Changes in exchange rate:	+/- 10%
Effect on profit before income taxes	658 / (658)
Effect on equity before income taxes	658 / (658)

Interest rate risk

For the years ended December 31, 2023, and 2022, the average interest rate was 100% and 57%, respectively.

The purpose of interest rate risk management is to minimize finance costs and limit the Company’s exposure to interest rate increases.

Variable-rate indebtedness exposes the Company’s cash flows to interest rate risk due to the potential volatility. Fixed-rate indebtedness exposes the Company to interest rate risk on the fair value of its liabilities as they could be considerably higher than variable rates. As of December 31, 2023 and 2022, about 4% and 9% of indebtedness was subject to variable interest rates.

For the years ended December 31, 2023 and 2022, the variable interest rate of loans denominated in USD stood at 9.32% and 4.55%, respectively. For the year ended December 31, 2022, the variable rate of loans denominated in ARS stood at 36.31%.

The Company expects to lessen its interest rate exposure by analyzing and assessing (i) the different sources of liquidity available in domestic and international financial and capital markets (if available); (ii) alternative (fixed or variable) interest rates, currencies and contractual terms available for companies in a sector, industry and risk similar to the Company’s; and (iii) the availability, access and cost of interest rate hedge contracts. Hence, the Company assesses the impact on profit or loss of each strategy on the obligations that represent the main positions to the main interest-bearing positions.

In the case of fixed rates and in view of current market conditions, the Company considers that the risk of an increase in interest rates is low; therefore, it does not expect substantial fixed rate debt risk.

For the years ended December 31, 2023, and 2022, the Company did not use derivative financial instruments to mitigate interest rate risks.
