Crude oil transportation concession, located in the Province of Río Negro (jointly with the Exploitation Concessions, the “Concessions”).

The Transaction consists of a two-phased agreement. The first phase was effective as of March 1, 2023 (the “Effective Date”) and will end no later than February 28, 2027.

Under the terms of the Transaction, from the Effective Date, Aconcagua: (i) will pay to Vista 26,468 in cash (10,000 paid on the signing date, and 10,734 and 5,734 to be paid in March 2024 and 2025, respectively); (ii) will become operator of the Concessions; and (iii) will pay 100% of Vista’s share of the capex, operating cost, and any other costs associated to the operation of the Concessions, including royalties and taxes.

Aconcagua will keep 60% of the Crude oil and Natural gas production from the Concessions. Additionally, Vista Argentina will have the right to purchase up to Aconcagua’s 60% share of the Natural gas produced by the Concessions at a price of 1 USD/MMBtu until the Final Closing Date.

Vista Argentina and Aconcagua will work jointly with the Provinces of Río Negro and Neuquén to negotiate an extension of the exploitation and transportation concession titles governing the Concessions, as per the terms set forth in the applicable regulation in Argentina.

Note 2. Basis of preparation and significant accounting policies

2.1 Bases of preparation and presentation

The unaudited interim condensed consolidated financial statements as of March 31, 2023 and December 31, 2022, and for the three-month periods ended March 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”). 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 March 31, 2023, and the results of operations for the three-month period ended March 31, 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 Company’s 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 three-month period ended March 31, 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”). To such end, oil and gas properties in Argentina were grouped into 3 (three) CGUs: (i) operated concessions of conventional oil and gas exploration and 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. The Company also identified just 1 (one) CGU in Mexico: (i) operated concessions of conventional oil and gas exploration and production.

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

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

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 March 31, 2023, and December 31, 2022, the Company did not identify indications of impairment related with goodwill and nonfinancial assets other than goodwill.

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”)

For the three-month periods ended March 31, 2023, and 2022, the Company received a net amount of 1,340 and 269, respectively.

As of March 31, 2023, and December 31, 2022, the receivables related to such plan stand at 2,560 and 3,772, respectively (see Note 16).

Other than mentioned above, there have been no significant changes in Argentina’s regulatory framework for the three-month period ended March 31, 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 three-month period ended March 31, 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 E&P 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 three-month periods ended March 31, 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.

The following chart summarizes noncurrent assets per geographical area:

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.

	Period from January 1, through March 31, 2023		Period from January 1, through March 31, 2022
Profit for the period, net		128,734		15,534
Weighted average number of ordinary shares		89,937,525		88,813,607

Profit for the period, net		128,734		15,534
Weighted average number of ordinary shares		97,920,497		95,464,397
Diluted earnings per share		1.315		0.163

As of March 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 out of the money. Consequently, they are not included in the weighted average number of ordinary shares to calculate diluted earnings per share.

⁽²⁾ Include 146,787 and 58,943 in noncurrent and current trade and other receivables, respectively, related to the accounts receivable recognized as a result of the Transaction mentioned in Note 1.2.1.

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 March 31, 2023, in general, accounts receivable has a 17-day term for sales of 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 March 31, 2023 and December 31, 2022 an allowance for expected credit losses was recorded in trade and other receivables for 196 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).

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

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

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

As of March 31, 2023	Level 1		Level 2		Level 3		Total
Assets
Financial assets at fair value through profit or loss
Short-term investments		281,470		—		—		281,470
Plan assets		5,782		—		—		5,782

Plan assets		5,703		—		—		5,703
Total assets		208,572		—		—		208,572

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 March 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 March 31, 2023	Carrying amount		Fair value		Level
Liabilities
Borrowings		659,567		516,081		2
Total liabilities		659,567		516,081

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 March 31, 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 three-month period ended March 31, 2023 and for the year ended December 31, 2022, ARS depreciated by about 18% and 72%, respectively.

The following chart shows the sensitivity to a reasonable change in the exchange rates 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 March 31, 2023
Changes in interest rates in Argentine pesos	+/- 50 %
Effect on profit or loss	(74,065) / 74,065
Effect on equity	(74,065) / 74,065

Interest rate risk

For the three-month periods ended March 31, 2023, and 2022, the average interest rate was 76% and 42%, 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 March 31, 2023, and December 31, 2022, about 7% and 9% of indebtedness was subject to variable interest rates. For the three-month period ended March 31, 2023, and for the year ended December 31, 2022, the variable interest rate of loans denominated in USD stood at 8.11% 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.

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

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