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 September 30, 2024 and December 31, 2023, and for the nine-month periods ended September 30, 2024 and 2023 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, 2024, and the results of operations for the nine-month period ended September 30, 2024. 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, 2023.

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, 2023, 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.

2.4 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”).

As of September 30, 2024, and December 31, 2023, the Company identified 2 (two) CGUs in Argentina: (i) operated exploitation concessions of unconventional oil and gas exploration and production; and (ii) non-operating concessions of conventional oil and gas exploration and production.

The Company also identified only 1 (one) CGUs in Mexico: (i) operated exploitation concessions of conventional oil and gas exploration and production, as of September 30, 2024, and December 31, 2023.

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 September 30, 2024, the Company did not identify indications of impairment or reversal of impairment related with goodwill and nonfinancial assets other than goodwill.

2.5 Regulatoryframework

A-	Argentina

2.5.1 General

2.5.1.1 Bases law

On June 28, 2024, Argentina’s House of Representatives approved Law of Bases and Points of Departure for the Freedom of Argentineans No. 27,742, as well as Law of Palliative and Relevant Tax Measures No. 27,743 (jointly, “the Bases Law”). On July 8, 2024, the Bases Law was enacted through Presidential Decrees No. 592/2024 and No. 593/2024, respectively, published in the Official Bulletin.

These laws are part of the Argentine Executive’s initiative to deregulate the Argentine economy and adjust the State’s operation and structure. Among its key measures, the Bases Law declare a public administrative, economic, financial, and energetic emergency for a year, and grant the Executive delegated legislative powers. Additionally, they include several reforms aimed at promoting registered employment and introduce a package of tax and social security measures, among others.

Hydrocarbons Law (No. 17,319) was also amended as follows:

(i)	It introduces the principle of maximizing corporate profit from the exploitation of resources as it removes the<br>concept of hydrocarbon self-supply previously in place;
(ii)	It authorizes the National or Provincial Executive, as the case may be, to issue storage permits and<br>authorizations for hydrocarbon processing in compliance with Law No. 17,319;
---	---
(iii)	It grants producers rights to trade, transport, and industrialize hydrocarbons produced and by-products, and prevents the National Executive from intervening or setting prices;
---	---
(iv)	It allows for the free export and import of hydrocarbons and<br>by-products. It also eliminates the Department of Energy’s authority to challenge export permits;
---	---
(v)	It amends the acquisition system and terms for unconventional concessions following the reconversion of<br>conventional concessions;
---	---
(vi)	It authorizes the regulatory authority to grant concessions for terms other than those established in<br>Hydrocarbons Law;
---	---
(vii)	It revises the extension system for new concessions;
---	---
(viii)	It mandates that new concessions be awarded through a bidding process upon expiration of existing concessions.<br>

The Bases Law also sets forth the creation of an Incentive Regime for Large Investments (the “RIGI” by Spanish acronym), which provides stability and offers tax, customs, and foreign exchange benefits for projects in various sectors, including the energy and oil & gas, subject to specific conditions.

The RIGI was established and published in the Official Bulletin on August 23, 2024, through Presidential Decree No. 749/2024, applicable to the oil & gas sector solely for the following activities: (i) construction of treatments plants, natural gas separation plants, oil & gas pipelines, and polyducts, and storage facilities; (ii) transportation and storage of liquid and gaseous hydrocarbons; (iii) petrochemical plants, including fertilizer production and refinery; (iv) natural gas production, collection, treatment, processing, fractioning, liquefaction and transportation for export of liquefied natural gas, as well as the infrastructure works required to develop the industry, and (v) offshore exploration and exploitation of liquid and gaseous hydrocarbons.

As of the date of issue of these interim condensed consolidated financial statements, the Bases Law had no significant impact on these.

2.5.1.2 Tax for an inclusive and solidary Argentina (“PAIS tax”)

On September 2, 2024, through Presidential Decree No. 777/2024, the Executive reduced to 7.50% the PAIS tax rate applicable to the acquisition of foreign currency for the payment of imports of goods and freight (See Note 30.2 of the consolidated financial statements as of December 31, 2023).

2.5.2 Gas market

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

2.6 Comparative Information

As of December 31, 2023 the Company has made a change in the “Export Duties” presentation in the “Royalties and others” (Note 5.3), which was previously included in “Revenues from contract with customers”.

The comparative information for the nine-month period ended September 30, 2023, has been reclassified to ensure consistent filing with the unaudited interim condensed consolidated financial statements as of September 30, 2024.

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.

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

The CODM considers as a single segment the exploration and production of crude oil, natural gas and liquefied petroleum gas (“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, 2024, and 2023, 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.

(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 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)

As of September 30, 2024, in general, accounts receivable has a 16-day term for sales of crude oil and a 57-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, 2024, and December 31, 2023, an allowance for expected credit losses was recorded in trade and other receivables for 43 and 52 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.

16.4 Fair value

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

16.4.1 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.<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 September 30, 2024 and December 31, 2023:

As of September 30, 2024		Level 1				Level 2				Level 3				Total
Assets
Financial assets at fair value through profit or loss
Plan assets			4,383				—				—				4,383
Short-term investments			151,715				—				—				151,715
Total assets		****	156,098	****		****	—	****		****	—	****		****	156,098	****
As of December 31, 2023		Level 1				Level 2				Level 3				Total
---	---	---	---	---	---	---	---	---	---	---	---	---	---	---	---	---
Assets
Financial assets at fair value through profit or loss
Plan assets			5,438				—				—				5,438
Short-term investments			156,163				—				—				156,163
Total assets		****	161,601	****		****	—	****		****	—	****		****	161,601	****

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, Level 2 and Level 3 from December 31, 2023, through September 30, 2024.

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

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.

16.5 Risk management objectives and policies concerning financial instruments

16.5.1 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 each period 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, 2023, except for the following:

16.5.1.1 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, 2024 and 2023, the Company performed foreign exchange currency 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, 2024 and 2023, ARS depreciated by about 20% and 98%, 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, 2024
Changes in exchange rate:		+/- 10%
Effect on profit or loss before income taxes		9,686 / (9,686)
Effect on equity before income taxes		9,686 / (9,686)

Interest rate risk

For the nine-month periods ended September 30, 2024, and 2023, the average market interest rate in Argentina was 62% and 95%, respectively.

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

Notes to the unaudited interim condensed consolidated financial statements as of September 30, 2024 and December 31, 2023 and for the nine-month periodsended September 30, 2024 and 2023

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

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, 2024, and December 31, 2023, about 3% and 4% of indebtedness was subject to variable interest rates, respectively.

For the nine-month period ended September 30, 2024, and for the year ended December 31, 2023, the variable interest rate of loans denominated in USD stood at 7.31% and 9.32%, respectively.

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 nine-month period ended September 30, 2024, and for the year ended December 31, 2023, the Company did not use derivative financial instruments to mitigate interest rate risks.
