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 December 31, 2022 and 2021, and for the years and for the three-month periods ended December 31, 2022 and 2021 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 December 31, 2022, and the results of operations for the year ended December 31, 2022. 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, 2021.

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, 2021.

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 transactions mentioned in Note 1.2 there were no changes in interest in Company subsidiaries during the year ended December 31, 2022.

2.4 Summary of significant accounting policies

2.4.1 Going concern

The Board oversees the Group’s cash position regularly and liquidity risk throughout the year to ensure that there are sufficient funds to meet expected financing, operating and investing requirements. Sensitivity tests are conducted to disclose the latest expense expectations, oil and gas prices and other factors so that the Group may manage risk.

Considering the macroeconomic context, the result of operations and the Group’s cash position, as of December 31, 2022 and 2021, the Directors asserted, upon approving the financial statements, that the Group may reasonably be expected to fulfill its obligations in the foreseeable future. Therefore, these interim condensed consolidated financial statements were prepared on a going concern basis.

2.4.2 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 December 31, 2022 and 2021 and for the years and for the three-month periods ended December 31, 2022 and 2021

(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 December 31, 2021, the Company recognized a reversal for 14,044 related to the CGU of operated concessions of conventional oil and gas exploration and production in Mexico, mainly driven by an increase in estimated recoverable volumes and an increase in oil and prices.

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:

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 November 13, 2020, through Presidential Decree No. 892/2020, the Argentine Executive approved Gas IV Plan, whereby it declared that the promotion of natural gas production is both a matter of public interest and a priority.

Moreover, through Presidential Decree No. 730/2022 of November 3, 2022, the Argentine government replaced Presidential Decree No. 892/2020, thus extending the term of the Gas IV Plan through December 31, 2028.

On December 15, 2020, through Resolution No. 391/2020, the Department of Energy awarded volumes and prices, for which the Company entered into agreements with Compañía Administradora del Mercado Mayorista Eléctrico SA (“CAMMESA”), Integración Energética Argentina S.A (“IEASA”) and other distribution licensees or subdistributors to supply natural gas for electric power generation and residential consumption, respectively.

Notes to the unaudited interim condensed consolidated financial statements as of December 31, 2022 and 2021 and for the years and for the three-month periods ended December 31, 2022 and 2021

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

The Company, through its subsidiary Vista Argentina, was awarded a base volume of 0.86 Mcm/day at an average price of 3.29 USD/MMBTU for a four-year period as from January 1, 2021, which was extended through December 31, 2028, by Resolution No. 860/2022 of December 22, 2022.

In 2022, the Company was granted a permit by the Department of Energy to export natural gas to Chile according to the following volumes:

(i)	0.15 Mcm/day for the period elapsed from January through April 2022;

(ii)	a variable volume for May through September 2022, and

(iii)

0.45 Mcm/day for the period elapsed from October 2022 through April 2023.

The Company exported a total of 51.4 Mcm to Chile during the year ended December 31, 2022.

For the years ended December 31, 2022 and 2021, the Company received a net amount of 3,149 and 3,660, respectively.

As of December 31, 2022 and 2021, the receivables related to such plan stand at 3,772 and 1,729, respectively (see Note 16).

Other than mentioned above, there have been no significant changes in Argentina’s regulatory framework for the year ended December 31, 2022 (see Note 2.5 to the annual consolidated financial statements as of December 31, 2021).

B-	Mexico

There have been no significant changes in Mexico’s regulatory framework during the year ended December 31, 2022 (see Note 2.5 to the annual consolidated financial statements as of December 31, 2021).

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 years ended December 31, 2022 and 2021, 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:


	As of December 31, 2022		As of December 31, 2021

Note 11. Earnings per share

Basic

Basic earnings per share is calculated by dividing the Company’s profit by the weighted average number of ordinary shares outstanding during the year / 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 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 period, no dilution effect is booked, as diluted earnings per share is equal to basic earnings per share.

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

		11,070		7,206

Other receivables		51,428		20,872

Total current trade and other receivables		90,406		46,096

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, 2022, in general, accounts receivable has a 15-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 December 31, 2022 and 2021 an allowance for expected credit losses was recorded for 231 and 406 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 following chart shows the Company’s financial assets and liabilities measured at fair value as of December 31, 2022 and 2021:


As of December 31, 2022	Level 1		Level 2		Level 3		Total

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, 2021, through December 31, 2022.

	As of December 31, 2022		As of December 31, 2021
Noncurrent
Warrants		—		2,544

Total noncurrent		—		2,544

On October 4, 2022 the meeting of holders of the Warrants issued by the Company (identified with the ticker symbol “VTW408A-EC001” - the “Warrants”), approved the amendments to the warrant indenture and the global certificate that covers such Warrants, by means of which a cashless exercise mechanism was implemented that entitles the holders, to obtain 1 Series A share representative of the capital stock of the Company for each 31 Warrants owned. As a result, a maximum of 3,215,483 shares will become outstanding once all Warrants are converted. Thus, as of December 31, 2022, a total of 2,038,643 Series A shares were issued (For further information see Note 29). They have no nominal value.

As of October 4, 2022, the liability for warrants was settled for 32,894, an amount equal to the 3,215,483 series “A” shares and was recognized under “Other equity instruments” (See Note 20).

Reconciliation of level 3 measurements at fair value:


	As of December 31, 2022			As of December 31, 2021
Warrants liability amount at beginning of year:		2,544			362

Other equity instruments		(32,894	)		—

Amount at end of year		—			2,544

The fair value of warrants was determined using the Black & Scholes model considering the expected volatility of the Company’s ordinary shares upon estimating the future volatility of Company share price. The risk-free interest rate for the expected useful life of warrants was based on the available return of benchmark government bonds with an equivalent remainder term upon the grant. The expected life was based on the contractual terms.

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, 2021, 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, 2022 and 2021, 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.

During the years ended December 31, 2022 and 2021, ARS depreciated by about 72 % and 22%, 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 December 31, 2022
Changes in interest rates in Argentine pesos		+/- 78 %
Effect on profit or loss		(57,193) / 57,193
Effect on equity		(57,193) / 57,193

Notes to the unaudited interim condensed consolidated financial statements as of December 31, 2022 and 2021 and for the years and for the three-month periods ended December 31, 2022 and 2021

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

Interest rate risk

For the years ended December 31, 2022 and 2021, the average interest rate was 57 % and 40%, 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, 2022 and 2021, about 9% and 16% of indebtedness was subject to variable interest rates. For the years ended December, 31 2022 and 2021, the variable interest rate of loans denominated in USD stood at 4.55% and 4.81%, respectively, and it amounted to 36.31% and 35.55%, respectively, for loans denominated in ARS.

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 years ended December 31, 2022 and 2021, the Company did not use derivative financial instruments to mitigate interest rate risks.

Note 27. Commitments and contingencies

Duplicar Plus Project implemented by Oleoductos del Valle SA (“Oldelval”)

On December 21, 2022, the Company, through its subsidiary Vista Argentina, was awarded a crude oil transportation capacity of 5,010 m3/day under the project to extend the current line from Allen to Puerto Rosales implemented by Oldelval (transportation concession holder) for 50,000 m3/day. Thus, the Company undertook to make an upfront investment of 118,000 between 2023 and 2025, to be recovered from the service monthly fee. As of the date of issuance of these financial statements, the Company made disbursements related to this commitment for a total amount of 16,378.

Other than mentioned above, there were no significant changes in commitments and contingencies for year ended December 31, 2022. For a description on the Company’s contingencies and investment commitments related to its oil and gas properties see Notes 29 and 30 to the annual consolidated financial statements as of December 31, 2021.

Note 28. Tax regulations

28.1 Income tax

General Resolution No. 5,248/2022

On August 16, 2022, the Federal Public Revenue Agency (“AFIP”) in Argentina issued General Resolution No. 5,248/2022 whereby it established one-time payment towards income tax.

For taxpayers whose tax assessed as of December 31, 2021, was equal to or higher than ARS 100,000,000 and which calculation base for the advance payments for the following tax period exceeded 0 (zero), the one-time payment towards income tax will amount to 25% of such calculation base. Such amount was paid in three equal and consecutive installments equivalents to 8,300 and computed as payment towards income tax for the year ended as of December 31, 2022.

Law No. 27,701

Law No. 27,701, published in the Official Bulletin on December 1, 2022, set forth the option to defer the tax adjustment for inflation for the first two fiscal years beginning as from January 1, 2022. Thus, a third of such positive adjustment may be distributed to the fiscal year in which the adjustment is assessed and the remaining two thirds, in equal parts, to the two subsequent fiscal years.

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

This alternative applies to the companies promoting investments in property, plant and equipment for an amount equal to or higher than ARS 30,000,000 during each of the two fiscal periods subsequent to the computation of the first third. Failing to comply with this requirement will result in the forfeiture of the benefit.

As of December 31, 2022, the Company, through its subsidiary Vista Argentina, applied the option mentioned above.

Other than mentioned above there were no changes in Argentina’s and Mexico’s tax regulations during the year ended December 31, 2022 (see Note 33 to the annual consolidated financial statements as of December 31, 2021).

Note 29. Subsequent events

The Company assessed events subsequent to December 31, 2022, to determine the need of a potential recognition or disclosure in these interim condensed consolidated financial statements. The Company assessed such events through February 23, 2023, date in which these financial statements were made available for issue.
