The unaudited interim condensed consolidated financial statements as of September 30, 2023 and December 31, 2022, and for the nine-month periods ended September 30, 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"). The Company prepared its interim financial statements on a condensed basis pursuant to IAS 34. Certain explanatory notes are included to describe the events and transactions that are relevant to understand the changes in the financial position as of September 30, 2023, and the results of operations for the nine-month period ended September 30, 2023. Therefore, these interim condensed consolidated financial statements do not include all the information and disclosures required in the annual financial statements and should be read together with the annual consolidated financial statements as of December 31, 2022.

These unaudited interim condensed consolidated financial statements were prepared using the same accounting policies as used in preparing the Company's consolidated financial statements as of December 31, 2022, except for the income tax expense that is recognized in each interim period based on the best estimate of the weighted average annual income tax rate expected for the full financial year.

They were prepared on a historical cost basis, except for certain financial assets and liabilities that were measured at fair value.

The figures contained herein are stated in US Dollars ("USD") and are rounded to the nearest thousand, unless otherwise stated.

2.2 New effective accounting standards, amendments and interpretations issued by the IASB adopted by the Company

The Group has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective.

2.3 Basis of consolidation

These unaudited interim condensed consolidated financial statements contain the financial statements of the Company and its subsidiaries. Other than the transaction mentioned in Note 1.2 there were no changes in interest in Company subsidiaries during the nine-month period ended September 30, 2023.

2.4 Summary of significant 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 Generated Units ("CGUs"). (See Note 3.2.2 to the annual consolidated financial statements as of December 31, 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.

2.5 Regulatory framework

A-

Argentina

2.5.1 Gas market

2.5.1.1 Argentine promotion plan to stimulate natural gas production: 2020-2024 supply and demand system ("Gas IV Plan")

On December 22, 2022, through Resolution No. 860/2022, the Department of Energy ("SE" by Spanish acronym) the Company, through its subsidiary Vista Argentina, was awarded a base volume of 0.86 Mcm/day at an annual average price of 3.29 USD/MMBTU, applicable until December 31, 2024.

On April 19, 2023, through Resolution No. 265/2023 of the SE, the base volume awarded to Vista was increased to 1.14 Mcm/day, maintaining the annual average price of 3.29 USD/MMBTU, applicable for a four-year period as from January 1, 2025.

Moreover, the Company was granted a permit by the SE to export natural gas to Chile according to the following volumes:

(i)

0.02 Mcm/day for the period elapsed from July through September 2023;

(ii)

0.43 Mcm/day for the period elapsed from October 2023 through April 2024;

(iii)

0.17 Mcm/day for the period elapsed from May 2024 through September 2024;

(iv)

0.43 Mcm/day for de period elapsed from October 2024 through December 2024; and

(v)

a variable volume until December 2024.

For the nine-month periods ended September 30, 2023 and 2022, the Company received a net amount of 3,491 and 1,077, respectively.

As of September 30, 2023 and December 31, 2022, the receivables related to such plan stand at 4,319 and 3,772, respectively (Note 16).

Other than mentioned above, there have been no significant changes in Argentina's regulatory framework for the nine-month period ended September 30, 2023 (see Note 2.5 to the annual consolidated financial statements as of December 31, 2022).

B-

Mexico

There have been no significant changes in Mexico's regulatory framework during the nine-month period ended September 30, 2023 (see Note 2.5 to the annual consolidated financial statements as of December 31, 2022).

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.

For the nine-month periods ended September 30, 2023, and 2022, the Company generated 99% and 1% of its revenues related to assets located in Argentina and Mexico, respectively.

The accounting criteria used by the subsidiaries to measure profit or loss, assets and liabilities of the segments are consistent with those used in these unaudited interim condensed consolidated financial statements.

Note 11. Earnings per share

a)

Basic

Basic earnings per share is calculated by dividing the Company's profit by the weighted average number of ordinary shares outstanding during the period.

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 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 period, no dilution effect is booked, as diluted earnings per share is equal to basic 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 September 30, 2023, in general, accounts receivable has a 16-day term for sales of oil and a 46-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 September 30, 2023 and December 31, 2022 an allowance for expected credit losses was recorded in trade and other receivables for 120 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 the Company'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.

Level 2: data other than the quoted prices included in Level 1 that are observable for assets or 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 (that is, non-observable data).

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 September 30, 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.

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 September 30, 2023 and 2022, the Company performed foreign exchange currency hedge transactions, and the impact in the results of the period 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.

During the nine-month period ended September 30, 2023 and for the year ended December 31, 2022, ARS depreciated by about 98% 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 of September 30, 2023

Changes in exchange rate:

+/-10%

Effect on profit before income taxes

9,479 /(9,479)

Effect on equity before income taxes

9,479 /(9,479)

Interest rate risk

For the nine-month periods ended September 30, 2023, and 2022, the average interest rate was 95% and 51%, 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 September 30, 2023, and December 31, 2022, about 4 % and 9% of indebtedness was subject to variable interest rates. For the nine-month period ended September 30, 2023, and for the year ended December 31, 2022, the variable interest rate of loans denominated in USD stood at 9.29% and 4.55%, respectively. For the year ended December 31, 2022, the variable rate of loans denominated in ARS stood at 36.31%.

Notes to the unaudited interim condensed consolidated financial statements as of September 30, 2023 and December 31, 2022 and for the nine-month periods ended September 30, 2023 and 2022

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

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 a major decrease in interest rates is low; therefore, it does not expect substantial fixed rate debt risk.

For the nine-month period ended September 30, 2023, and for the year ended December 31, 2022, the Company did not use derivative financial instruments to mitigate interest rate risks.

27.1 "Vaca Muerta Norte" Pipeline Agreement

On May 16, 2023, through its subsidiary Vista Argentina, the Company entered into an agreement with YPF S.A. ("YPF"), Equinor Argentina B.V. Sucursal Argentina ("Equinor") and Shell Argentina S.A. ("Shell") (jointly the "Parties") , whereby YPF, in its capacity as the hydrocarbon transportation concession owner of the pipeline (the "Pipeline") located in the Province of Neuquén from "La Amarga Chica" area to "Puesto Hernández" area (the "Transportation Concession"), assigns to the remainder parties an undivided interest of the rights and obligations over the Transportation Concession amounting to: (i) 3.5% (three point five percent) in favour of Equinor; (ii) 13.3% (thirteen point three percent) to Shell, and (iii) 8% (eight percent) to Vista Argentina (the "Assignment").

The Transportation Concession will be used to carry off the production of all oil and gas areas in which the Parties have, now or hereafter, a Pipeline interest.

In addition, the Parties signed (i) an agency agreement whereby Equinor, Shell and Vista Argentina entrusted YPF with the acts and tasks required to build the Pipeline and set the costs and expenses to be contributed by each concession holder in proportion to their interests, and; (ii) an agreement for the joint construction of the Pipeline, which establishes the terms and conditions to operate, maintain and use the Pipeline transportation capacity and the Transportation Concession.

Moreover, this Assignment is pending approval by the Executive Power of the Province of Neuquén.

As of the date of these unaudited interim condensed consolidated financial statements, Vista Argentina paid 16,912 related to this agreement.

Other than mentioned above, there were no significant changes in commitments and contingencies for the nine-month period ended September 30, 2023 (see Notes 28 and 29 to the annual consolidated financial statements as of December 31, 2022).

Note 28. Tax regulations

A- Argentina

28.1. Income tax

On July 20, 2023, the Federal Public Revenue Agency ("AFIP" by Spanish acronym) issued General Resolution No. 5,391/2023, which establishes a one-time payment towards income tax. 

For taxpayers whose taxable income as of December 31, 2022, before computing prior-year NOLs, is equal to or higher than ARS 600,000,000, and who have not assessed income tax for that same period, this one-time payment towards income tax amounts to 15% of such taxable income. This amount is payable in 3 (three) equal and consecutive instalments as from August 2023 and will be computed towards income tax assessed for the year ended December 31, 2023, or the following years.

As of September 30, 2023, the Company, through its subsidiary AFBN S.R.L., made payments towards income tax for 653.

28.2 Tax for an inclusive and solidary Argentina ("PAIS Tax")

On July 24, 2023, through Presidential Decree No. 377/2023, the Argentine Executive set forth that PAIS tax shall also be applied to the acquisition of foreign currency for the payments of imports of goods and services, at a 7.5% rate for imports of goods and freight, and at a 25% for imports of services. This tax extension does not apply to imports of goods related to power generation.

Other than mentioned above, there were no significant changes in Argentina's and Mexico's tax regulations during the nine-month period ended September 30, 2023 (see Note 31 to the annual consolidated financial statements as of December 31, 2022).

Note 29. Subsequent events

The Company assessed events subsequent to September 30, 2023, to determine the need of a potential recognition or disclosure in these interim condensed consolidated financial statements. The Company assessed such events through October 24, 2023, date in which these financial statements were made available for issue.

On October 3, the Department of Energy Resolution No. 808/23, as amended, (hereinafter, the "Resolution") authorized that, under certain conditions, exporters of crude oil, petroleum oil, gas and by-products settle the funds obtained from their exports at a preferential exchange rate. Such rate results from bringing 75% of the foreign currency into Argentina through the single and free foreign exchange market and the remainder 25% through securities bought in foreign currency and sold in local currency ("O&G dollar").

To be eligible to the O&G dollar, exports should meet certain criteria, including settling such exports from October 2, 2023, through October 20, 2023, and exporting these products no later than November 30, 2023.

On October 4, 2023, Vista Argentina paid interest for an amount of 110 corresponding to loan agreements signed with Banco Santander International in July 2021 and January 2022.

On October 17, 2023, Vista Argentina entered into two export prefinancing agreements with Citibank N.A. in the amount of 38,000 for 70 (seventy) days subject to early settlement, at an annual interest rate of SOFR + 9%.

On October 17, 2023, Vista Argentina entered into an export prefinancing agreement with Itaú Unibanco S.A. in the amount of 10,000 for 60 (sixty) days subject to early settlement, at an annual interest rate of 8.75%.

There are no other events or transactions between the closing date and the date of issuance of these unaudited interim condensed consolidated financial statements that could significantly affect the Company's financial position or profit or loss.
