We maintain our books and records in U.S. Dollars, which is the presentation currency for our financial 
statements and also the functional currency of our operations.  
The financial information contained, or referred to, in this annual report includes the audited consolidated

No Emerging Growth Company Status 
As of December 31, 2023, we have ceased to be an emerging growth company and are therefore no longer 

 
2 
 
able to take advantage of certain exemptions from various requirements applicable to other public companies that are 
emerging growth companies including, most significantly, not being required to comply with the auditor attestation 
requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (“SOX”).  As such, our independent registered public 
accounting firm is now required to attest to the effectiveness of our internal control over financial reporting. 
Public Company in Mexico  
Because we are a public company in Mexico, investors can access our historical financial statements 
published in Spanish on the Mexican Stock Exchange’s (Bolsa Mexicana de Valores, S.A.B. de C.V.), the Mexican 
National Banking Commission’s (Comisión Nacional Bancaria y de Valores) (“CNBV”)’s and our websites at 
www.bmv.com.mx, www.gob.mx/cnbv and www.vistaenergy.com, respectively. The information found on the 
Mexican Stock Exchange’s, the CNBV’s and our websites is not a part of this annual report.  
Non-IFRS Financial Measures 
In this annual report, we present ROACE, Net Debt, Adjusted EBITDA, Adjusted EBITDA Margin and 
Adjusted Net Income (in each case, as defined below), which are non-IFRS financial measures. A non-IFRS financial 
measure is generally defined as a numerical measure of a registrant’s historical or future financial performance, 
financial position or cash flows that: (i) excludes amounts, or is subject to adjustments that have the effect of 
excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance 
with IFRS in the statement of income, balance sheet or statement of cash flows (or equivalent statements) of the 
issuer; or (ii) includes amounts, or is subject to adjustments that have the effect of including amounts, that are 
excluded from the most directly comparable measure so calculated and presented.  
We define Adjusted EBITDA as profit for the year, net, plus income tax expense, financial income 
(expense), net, depreciation, depletion and amortization, transaction costs related to business combinations and gain 
from asset disposals, restructuring and reorganization expenses, gain related to the transfer of conventional assets, 
other non-cash costs related to the transfer of conventional assets and (reversal) impairment of long-lived assets. 
Effective for periods starting on or after January 1, 2023, the Company has adjusted the definition of Adjusted 
EBITDA compared to prior annual reports by excluding gain related to the transfer of conventional assets and other 
non-cash costs related to the transfer of conventional assets. We believe that excluding gain related to the transfer of 
conventional assets and other non-cash costs related to the transfer of conventional assets results in a better 
representation of the Company’s returns following the Conventional Assets Transaction (as defined below), given that 
profit and losses generated by the Conventional Assets Transaction have a non-recurrent impact only during the 
duration of the transaction, and excluding them allows our management and investors to better analyze our core 
operating performance on a consistent basis from period to period. Given that the Conventional Assets Transaction 
became effective on March 1, 2023, a recast for prior periods was not necessary. We believe that the nature of the 
restructuring and reorganization expenses were such that they are not reasonably likely to recur within two years as 
they are mainly related to permanent reductions in our workforce derived from our business combinations, and that 
restructuring and reorganization expenses and transaction expenses are not normal, recurring operating expenses. We 
believe that by excluding restructuring and reorganization expenses and transaction costs related to business 
combinations and gain from asset disposals, we are able to provide supplemental information for our management and 
investors to analyze our core operating performance on a consistent basis from period to period. In addition, the 
(reversal) impairment of long-lived assets was excluded from the determination of our Adjusted EBITDA because it 
corresponds to an adjustment to the valuation of our fixed assets which charge is similar in nature to the depreciation 
of property, plant and equipment. This metric allows management and investors to analyze our operating performance 
on a consistent basis from period to period. In this regard, the elimination of these costs and expenses does not result 
in a reduction of operating expenses necessary to conduct our business. In light of the foregoing factors, our 
management excludes restructuring and reorganization expenses, transaction costs related to business combinations 
and gain from asset disposals, gain related to the transfer of conventional assets and other non-cash costs related to the 
transfer of conventional assets and (reversal) impairment of long-lived assets from our Adjusted EBITDA to facilitate 
reviews of operational performance and as a basis for strategic planning. Our management believes that excluding 
such items will allow investors to supplement their understanding of our short-term and long-term financial trends.

We define Adjusted Net Income as profit for the year, net, plus deferred income tax (expense), changes in 
fair value of warrants, gain related to the transfer of conventional assets, other non-cash costs related to the transfer of 
conventional assets and (reversal) impairment of long-lived assets. Effective for periods starting on or after January 1, 
2023, the Company has adjusted the definition of Adjusted Net Income compared to prior annual reports by excluding 
gain related to the transfer of conventional assets and other non-cash costs related to the transfer of conventional 
assets. We believe that excluding gain related to the transfer of conventional assets and other non-cash costs related to 
the transfer of conventional assets results in a better representation of the Company’s returns following the 
Conventional Assets Transaction, given that profit and losses generated by the Conventional Assets Transaction have 
a non-recurrent impact only during the duration of the transaction, and excluding them allows our management and 
investors to better analyze our ongoing performance on a consistent basis from period to period. Given that the 
Conventional Assets Transaction became effective on March 1, 2023, a recast for prior periods was not necessary. 
Deferred income tax (expense) was excluded as they relate to recognition of temporary differences between the tax 
bases of assets and liabilities and the carrying amounts in the financial statement using the liability method. Changes 
in the fair value of warrants were excluded because they correspond to an adjustment valuation of financial liabilities 
assumed by the Company, likewise (reversal) impairment of long-lived assets were excluded from the determination 
of our adjusted net income because they correspond to an adjustment to the valuation of our long-lived assets. Our 
management believes that excluding such items will allow investors to facilitate the comparison performance from 
period to period by removing these identified non-cash items that are mainly driven by external factors and that affect 
(benefit) the Company’s net income.  
We define Net Debt as current and non-current borrowings minus cash, bank balances and other short-term 
investments.  
We define Adjusted EBITDA Margin as the ratio of Adjusted EBITDA to revenue from contracts with 
customers plus Gain from Exports Increase Program. Effective for periods starting on or after January 1, 2023, the 
Company has adjusted the definition of Adjusted EBITDA Margin compared to prior annual reports to add Gains 
from the Exports Increase Program in the denominator, as it believes that this results in a better representation of the 
Company’s margins given that it is accounted for in the Adjusted EBITDA which is the numerator, making the ratio 
consistent by having the impact both in numerator and denominator. Given that the Exports Increase Program was 
established in October 2023, a recast for prior periods was not necessary.  
We define return on average capital employed (“ROACE”) as Adjusted EBITDA plus depreciation, depletion 
and amortization, gain related to the transfer of conventional assets and other non-cash costs related to the transfer of 
conventional assets, divided by the sum of the average total debt and average total shareholders’ equity. For purposes 
of this definition, total debt is comprised of current borrowings, non-current borrowings, current lease liabilities and 
non-current lease liabilities. Effective for periods starting on or after January 1, 2023, the Company has adjusted the 
definition of ROACE compared to prior annual reports to add gains related to the transfer of conventional assets and 
other non-cash costs related to the transfer of conventional asset in the numerator. We believe that adding gain related 
to the transfer of conventional assets and other non-cash costs related to the transfer of conventional assets to the 
numerator results in a better representation of the Company’s returns following the Conventional Assets Transaction, 
given that profit and losses generated by the Conventional Assets Transaction are accounted for in the profit for the 
year, net and therefore in total shareholder´s equity which is included in the denominator, making the ratio consistent 
by having the impact both in numerator and denominator. Given that the Conventional Assets Transaction became 
effective on March 1, 2023, a recast for prior periods was not necessary. Our management believes ROACE can be a 
valuable tool to measure the efficiency of the utilization of the capital we employ, whether financed by equity or debt. 
We present Adjusted EBITDA, Adjusted EBITDA Margin, Net Debt, Adjusted Net Income and ROACE 
because we believe they provide investors with supplemental measures of the financial condition and performance of 
our core operations that facilitate period to period comparisons on a consistent basis. Our management uses Net Debt, 
Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income and ROACE, among other measures, for 
internal planning and performance measurement purposes. Net debt, Adjusted EBITDA, Adjusted EBITDA Margin, 
Adjusted Net Income and ROACE are not measures of liquidity or operating performance under IFRS and should not 
be construed as alternatives to net profit, operating profit, or cash flow provided by operating activities (in each case, 
as determined in accordance with IFRS). Net Debt, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net 
Income and ROACE, as calculated by us, may not be comparable to similarly titled measures reported by other 
companies. For a reconciliation of Net Debt, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income 
and ROACE to the most directly comparable IFRS financial measure, see “Item 5—Operating and Financial Review 
and Prospects—Operating Results.”

RISK FACTORS  
You should carefully consider the following risk factors in evaluating us and our business before investing in Vista. In 
particular, you should consider the risks related to an investment in companies operating in Argentina, Mexico and 
Latin America generally, for which we have included information in these risk factors to the extent that information is 
publicly available. In general, investing in the securities of issuers whose operations are located in emerging market 
countries such as Mexico and stand-alone countries such as Argentina involve a higher degree of risk than investing 
in the securities of issuers whose operations are located in the United States or other more developed countries. If 
any of the risks discussed in this annual report actually occur, alone or together with additional risks and 
uncertainties not currently known to us, or that we do not presently consider material, our business, financial 
condition, results of operations and prospects may be materially adversely affected. If this were to occur, the value of 
our series A shares or ADSs may decline and you may lose all or part of your investment. When determining whether 
to invest, you should also refer to the other information contained in this annual report, including the Audited 
Financial Statements and the related notes thereto. Our actual results could differ materially and adversely from 
those anticipated in this annual report.  
Risk Factor Summary 
The following summarizes the main risks to which we are subject. You should carefully consider all of the 
information discussed below in “—Detailed Risk Factors” for a comprehensive description of these and other risks.  
Risks Related to Our Business and Industry:  
As an oil and gas company, our business and industry is subject to particular risks, such as exploration, 
drilling, completion, production, equipment and resources, gathering, treatment and transportation risks; risks related 
to natural hazards, weather conditions, and mechanical difficulties; fluctuations and regulation of international and 
domestic oil prices; the availability of financial resources for our business plan and its corresponding costs; inflation; 
government regulation; and contractions in demand of crude oil and natural gas or any of their by-products. 
Additional risks exist in light of the conflict between Russia and Ukraine and the conflicts involving Israel, Hamas 
and Iran in the Middle East, and the associated economic and trade sanctions and restrictions that have been imposed 
or may be imposed in the future as a result of such conflicts or others. Additionally, changes in U.S. trade and other 
policies under the Trump administration may adversely impact our business, financial condition, and results of 
operations. Also, as a company which primarily operates in Argentina and Mexico, our business may be affected by 
changes in those markets. 
Our business operations require significant and long-term capital investments and maintenance costs. Our 
liquidity, business activities, profitability and ability to compete in the market may be adversely affected if we are not 
able to acquire and correctly use necessary new technologies in connection with future drilling projects, obtaining 
financing for such projects, obtain and maintain and/or partners to develop and maintain our business activities.  

 
11 
 
The enhanced focus on climate change and the transition to lower carbon energy sources on the part of the 
international community, governments, and investors, promote an increase in the use of energy from renewable 
sources. This energy transition could significantly impact our industry and business, resulting in increased operating 
costs, reduced demand for the oil and natural gas we produce, and reputational risks in connection with our business 
activities. If we fail to meet the pace and extent of society’s changing demands for lower carbon energy as the energy 
transition unfolds, we could fail in sustaining and developing our business. Further, adverse climate conditions may 
adversely affect our results of operations and our ability to conduct drilling operations. Additionally, adverse climate 
conditions could negatively impact the Argentine economy, which could in turn affect our results of operations. 
Risks Related to our Company:  
Most of our producing properties and total estimated proved reserves are geographically concentrated in 
Argentina. The results of our planned development programs in new or emerging shale development areas and 
formations may be subject to more uncertainties than programs in more established areas and formations. As such, we 
may fail to fully identify problems with any properties we acquire, and as such, assets we acquire may prove to be 
worth less than we paid because of uncertainties in evaluating recoverable reserves and potential liabilities. We may 
not be able to acquire, develop or exploit new reserves, which could decrease the volume of our reserves over time 
and could, in turn, adversely affect our financial condition and our results of operations. We also may be subject to 
unknown or contingent liabilities related to our recent and future acquisitions. 
The oil and gas industry is competitive and our ability to achieve our strategic objectives depends on our 
ability to successfully compete in the market.  
We may also be parties to labor, commercial, civil, tax, criminal, environmental and administrative 
proceedings that, either alone or in combination with other proceedings, could, if resolved in whole or in part 
adversely to us, result in the imposition of material costs, fines, judgments or other losses. Additionally, we are 
subject to anti-corruption, anti-bribery, anti-money laundering and economic sanctions laws and regulations of 
Mexico, Argentina and other nations. Our failure to comply with these laws could result in penalties, which could 
harm our reputation and have an adverse effect on our reputation, business, financial condition and results of 
operations. Our operations may pose risks to the environment, and any climate change legislation or regulations 
restricting emissions of greenhouse gases and legal frameworks promoting an increase in the participation of energies 
from renewable sources could significantly impact our industry and result in increased operating costs and reduced 
demand for the oil and natural gas we produce. 
Risks Related to the Argentine and Mexican Economic and Regulatory Environments:  
Investors may be faced with risks inherent to investing in a company operating in stand-alone and emerging 
markets, such as Argentina and Mexico. Some of these risks may include, among others, the economic and political 
conditions in Argentina and Mexico, Argentina’s ability to obtain financing from international markets, changing 
regulation in the countries in which we operate, direct and indirect restrictions on imports and exports under 
Argentine law, current or potential Argentine exchange controls, the imposition of export duties and other taxes, 
inflation, significant fluctuations in the value of the Argentine Peso, criminal activity in Mexico, and joint and several 
tax liability. Recent reforms and amendments to Mexican laws and regulations may adversely affect our operations if 
applicable to our activities.  
Risks Related to our series A shares and the ADSs:  
The series A shares and ADSs are traded in more than one market, and this may result in price variations. 
Dividend distributions to holders of our series A shares will be made in Mexican Pesos.  
Also, if securities or industry analysts do not publish research reports about our business, or publish negative 
reports about our business, the price and trading volume of our series A shares and the ADS could decline.  
As a foreign private issuer, we have different disclosure and other requirements than U.S. domestic 
registrants. We are also permitted to rely on exemptions from certain NYSE corporate governance standards 
applicable to U.S. issuers, including the requirement that a majority of an issuer’s directors consist of independent 
directors. This may afford less protection to holders of our ADSs. 

 
12 
 
ADS holders may also be subject to additional risks related to holding ADSs rather than series A shares. For 
example, ADS holders may be unable to exercise voting rights with respect to the shares underlying the ADSs at our 
shareholders’ meetings, and preemptive rights may be unavailable to non-Mexican holders of ADSs. Additionally, 
our bylaws, in compliance with Mexican law, restrict the ability of non-Mexican shareholders to invoke the protection 
of their governments with respect to their rights as shareholders. Our bylaws also contain provisions aimed at 
restricting the acquisition of our shares and restricting the execution of voting agreements among our shareholders. 
ADSs holders may not be entitled to a jury trial with respect to claims arising under the deposit agreement, which 
could result in less favorable outcomes to the plaintiff(s) in any such action.  
If we fail to maintain an effective system of internal control over financial reporting, we may not be able to 
accurately report our financial results or prevent fraud.  
Detailed Risk Factors 
Risks Related to Our Business and Industry  
The oil and gas industry is subject to particular operational and economic risks.  
Oil and gas E&P activities are subject to particular economic and industry-specific operational risks, some of 
which are beyond our control, such as drilling, completion, production, equipment, gathering, treatment and 
transportation risks, as well as natural hazards and other uncertainties, including those relating to the physical 
characteristics of onshore and offshore oil or natural gas fields. Our operations may be curtailed, delayed or canceled 
due to bad weather conditions, mechanical difficulties, shortages or delays in the delivery of equipment or the 
construction of roads to access drilling sites, works related to third-party vendors, road blocks, compliance with 
governmental requirements (including any delays in obtaining the relevant permits), fire, explosions, blow-outs, pipe 
failure, abnormally pressured formations, supply chain bottlenecks, lockdown restrictions on the general population 
and reduced hydrocarbons demand due to a pandemic, such as COVID-19, and environmental hazards, such as oil 
spills, gas leaks, ruptures or discharges of toxic gases or natural disasters preventing us from accessing the drilling 
sites. Drilling may be unprofitable, not only with respect to dry wells, but also with respect to wells that are 
productive but do not produce sufficient revenues to return a profit after drilling, completion, operating and other 
costs are considered.  
We are exposed to the effects of fluctuations and regulation of international and domestic oil prices. In 
addition, limitations on local pricing of our products in Argentina and Mexico may adversely affect our results of 
operations. 
Most of our revenues in Argentina and Mexico are derived from sales from oil and natural gas. During 2024, 
49% of our oil sales volumes were exported, and we expect to continue exporting a substantial portion of our volumes 
in the future. We are, therefore, exposed to pricing risk in both the international and domestic markets, especially the 
Argentine domestic market. 
International and domestic oil and gas prices have fluctuated significantly in recent years and are likely to 
continue fluctuating in the future. Factors affecting international crude oil prices include: political developments in 
crude oil producing regions, particularly in the Middle East, the ongoing conflicts between Russia and Ukraine, Israel, 
Hamas and Iran, and China and Taiwan; the ability of the OPEC and other crude oil producing nations to set and 
maintain crude oil production levels and prices; macroeconomic conditions, including inflation and GDP growth; 
global and regional supply and demand for crude oil, gas and related products; investment in new projects to bring 
new oil production volumes to the market; global supply chain disruptions, and shipping bottlenecks, competition 
from other energy sources, the effects of a pandemic (such as COVID-19) or epidemic and any subsequent mandatory 
regulatory restrictions or containment measures, domestic and foreign government regulations, trade conflicts, 
weather conditions, and global and local conflicts, war, or acts of terrorism. We cannot predict how these factors will 
influence the prices of oil and related oil products, and we have no control over them. Price volatility curtails the 
ability of industry participants to adopt certain long-term investment decisions given that returns on investments 
become unpredictable. 
Secondly, the domestic crude oil price has fluctuated in the past in Argentina and Mexico not only due to 
international prices and the risks outlined above, but also due to local taxation, regulations affecting 
commercialization in the domestic and export markets in connection with crude and refined hydrocarbons, 

 
13 
 
macroeconomic conditions, the impact of a pandemic on general economic activity and therefore crude oil demand 
and refining margins. The domestic crude oil price is also subject to local price limitations imposed by the Argentine 
and Mexican governments. During 2023, the average annual Brent crude oil price stood at US$82.3/bbl, and our 
average realization price was US$66.7/bbl, 19% below the average annual Brent crude oil price and 7% below export 
parity for Medanito oil price, which stood at US$72.0/bbl. During 2024, the difference between our average realized 
price and export parity for Medanito oil narrowed to 2%. However, we cannot guarantee that this gap will not widen 
in the future. More recently, in April 2025 the announcement by President Trump that the United States would 
impose sweeping tariffs on all countries resulted in generalized market volatility and a decrease in the price of many 
commodities, including crude oil. A sustained decrease in oil prices could materially and adversely affect our 
business, financial condition and results of operations. 
The determination by the Argentine and Mexican governments to fix, or indirectly intervene, to generate 
local crude oil prices at values below export parity could have an adverse effect on our results of operations, financial 
condition, and cash flows. In the event that local prices were reduced through any of the factors described above, 
which we cannot control, this could affect the economic performance of our existing and future projects, generating a 
loss of reserves as a result of changes in our development plans, our assumptions and our estimates, and consequently 
affect the recovery value of certain assets. A decline in realized crude oil prices for an extended period of time (or if 
prices for certain products fail to keep pace with cost increases) could adversely affect both the economic viability of 
our drilling projects and, consequently, our ability to meet our operational and financial targets. These price declines 
could result in changes to our development plans, reduced capital expenditures, failure of our joint venture partners to 
approve investment projects, a loss of proved developed reserves and proved undeveloped reserves, an adverse effect 
on our ability to improve our hydrocarbon recovery rates, find new reserves, develop unconventional resources, carry 
out certain capital expenditure plans, meet our long-term targets and service our financial debt obligations. A decline 
in realized crude oil prices could also lead to a deterioration in our financial coverage ratios and impairment charges. 
We cannot predict whether, or to what extent, the potential consequences of such actions could affect our business, 
impact our production, or affect our financial condition and results of operations, including having enough cash to 
service our financial debt obligations.  
See also “—A potential increase in crude oil supply in the global market could lead to excess supply and 
result in a reduction in global crude oil prices.” 
Our business could be adversely affected by a decline in general economic conditions or a weakening of 
the broader energy industry, and inflation may adversely affect our financial position and operating results. 
A prolonged economic slowdown or recession, adverse events relating to the energy industry, or regional, 
national, or global economic conditions and factors, could negatively impact our operations and therefore adversely 
affect our results. The risks associated with our business are more acute during periods of economic slowdown or 
recession because such periods may be accompanied by decreased demand for oil and natural gas, and decreased 
prices for oil and natural gas. 
Supply chain pressures in global production, trade and logistics and demand increases may lead to price 
inflation in the energy sector. In addition, macroeconomic conditions in Argentina and Mexico may result in cost 
inflation for goods and services purchased in local currency. Inflationary factors, such as increases in the labor costs, 
material costs, and overhead costs, may also adversely affect our financial position and operating results. An increase 
in our costs due to inflation could offset any price increases of our products and services resulting in an adverse effect 
on our operating results, including having enough cash to service our financial debt obligations. 
We are exposed to contractions in demand of crude oil and natural gas and contractions in demand of 
any of their by-products. 
Demand for our crude oil and gas products is largely influenced by the economic activity and growth in 
Argentina, Mexico and globally. For example, the efforts of the Federal Reserve of the United States and other central 
banks globally to contain inflation through increase in interest rates, could lead to lower economic growth, and even 
economic recession in certain economies, or at a global level. In addition, low economic growth in major emerging 
economies, such as China or India, could negatively impact oil demand. This could have an adverse effect on demand 
for crude oil and crude oil prices, and therefore impact negatively on our business. Demand for our products is subject 
to volatility in the future. Demand for crude oil by-products, such as gasoline, may contract under certain conditions, 
particularly during economic downturns, or due to governmental subsidies and/or changes in consumer preferences 

 
14 
 
following from the energy transition currently underway. 
A contraction of the demand of our products would adversely affect our revenues, causing economic losses 
to our Company. In addition, a contraction in the demand and/or prices of our products can impact the valuation of 
our reserves. Additionally, in periods of lower commodity prices, we may curtail production and capital spending or 
may defer or delay drilling wells because of lower cash generation. Continuous poor economic performance could 
eventually impair our ability to repay our financial debt, lead to a deterioration in our financial coverage ratios and 
impairment charges. A contraction of crude oil demand could also affect us financially, including our ability to pay 
our suppliers for their services, or service our financial debt, which could, in turn, lead to further operational distress. 
A potential increase in crude oil supply in the global market could lead to excess supply and result in a 
reduction in global crude oil prices. 
Crude oil is a global commodity and, as such, its price is determined, among other factors, by physical supply 
and demand. As a crude oil producer, we are exposed to fluctuations in crude oil prices. For example, in early March 
2020, OPEC+ countries failed to reach an agreement on extending or increasing oil production cuts in light of a decrease 
in demand due to the COVID-19 pandemic. Shortly thereafter, Saudi Arabia, the world’s largest oil exporter, through 
its state-owned company Saudi Aramco, decided to lower the official selling price (OSP) of its Arab light crude by 
approximately US$8/bbl, the largest monthly decrease in 20 years, and announced plans to increase production to at 
least 10 million bbl/d as of April 2020. As a result, Brent crude oil prices dropped by US$10.9/bbl (or 24.1%) to 
US$34.4/bbl, representing the steepest one-day decline since 1991. From March 16 to April 2, 2020, Brent crude oil 
prices remained below US$30/bbl, reaching a low of US$22.72/bbl on March 30, 2020. 
 
There are currently several projects under development in different countries, such as Brazil, Guyana and the 
U.S., which could potentially add supply volumes to the market that, added up, could be greater than the short-term 
growth in crude oil demand, leading to excess supply. In such a case, crude oil prices could fall below current levels, 
which could negatively impact our revenues, and materially affect our business, financial condition and results of 
operations.  
 
In addition, OPEC+ countries have, according to their own reports, curtailed oil production. If the OPEC+ 
countries, as a group or individually, were to unwind such curtailments at a fast pace compared to the increase in 
short-term oil demand, this could result in excess supply, leading to significant declines in crude oil prices compared 
to current levels, which could in turn negatively impact our revenues, and materially affect our business, financial 
condition and results of operations. 
 
The conflict involving Russia and Ukraine, and the associated new, additional, and/or enhanced 
economic and trade sanctions and restrictions that have been imposed by various countries, could have a material 
adverse effect on our business, financial condition and results of operations. 
The conflict involving Russia and Ukraine has recently had and will likely continue to have significant 
international economic effects, including increased inflation, supply chain problems, market volatility and an impact 
on commodity prices. The conflict and its effects could exacerbate the current slowdown in the global economy and 
could negatively affect the ability of some of our customers with exposure to the Russian and/or Ukrainian markets to 
pay for our products. 
In addition, the conflict has resulted in the imposition of economic and trade sanctions and restrictions 
targeting Russia and certain Russian economic sectors and companies by the United States, the European Union, the 
United Kingdom and other major countries. The severity of these sanctions could worsen and contribute to shortages 
of raw materials and commodities, which in turn could lead to higher levels of inflation and disruptions in the global 
supply chain. Disruptions in the global supply chain could affect, in particular, the energy sector and could lead to 
supply chain difficulties in local markets. Due to the uncertainties inherent to the scale and duration of the conflict 
and its direct and indirect effects, it is not reasonably possible to estimate the impact this conflict will have on the 
global economy and financial markets, on the economies of the countries in which we operate and, consequently, our 
business, financial condition and results of operations. 
Also, our revenues and our profitability are heavily dependent on the prices we receive from our sales of oil 
and natural gas. Oil prices are particularly sensitive to actual and perceived threats to global political stability and to 
changes in oil production in, and oil supply from, various key countries, including Russia. The conflict has led to an 

 
15 
 
increase in international oil prices, which creates transitory increases in the revenues of E&P companies around the 
globe. In addition, it has also led to increased volatility in global commodities in general and hydrocarbon prices. We 
cannot predict whether such volatility will lead to further price increases or, on the contrary, lead to a general 
downturn in economic activity, or lower oil and gas prices, and therefore adversely affect our profitability. A 
sustained increase in oil prices could accelerate the transition to alternative energy sources, leading to an 
unpredictable decline in prices in the medium to long term, which could adversely affect our business, financial 
condition, and results of operations. Such price increases could also lead to energy shortages and an increasing 
amount of the global population, including in Argentina and Mexico, without access to energy supplies. It could also 
lead to new regulation by the Argentine and/or Mexican governments to further de-couple domestic energy pricing 
from international energy pricing or restrict energy-related exports from Argentina or Mexico, which would affect our 
business. Additionally, changes to worldwide oil prices and demand could cause turmoil in the global financial 
system, and in turn materially affect our business, financial condition and results of operations. 
The conflicts involving Israel, Hamas and Iran could have a material adverse effect on our business, 
financial condition and results of operations. 
Beginning in October 2023, Israel and Hamas have been involved in a serious and escalating armed conflict, 
which also involved other countries in the Middle East, such as Iran (which more recently engaged in direct conflict 
with Israel). A sharper escalation of these conflicts could lead to the involvement of other countries around the globe. 
The war could have a material negative impact on oil prices and global growth as well as further global economic 
consequences, including but not limited to the possibility of increased volatility in energy prices, severely diminished 
liquidity and credit availability, declines in consumer confidence, scarcity of certain raw materials and products, 
declines in economic growth, increases in inflation rates and uncertainty about economic and political stability. 
Although the length and impact of the ongoing conflict is unpredictable, such conflict has created and could lead to 
further market disruptions, including significant volatility in commodity prices, credit and capital markets. Due to the 
uncertainties inherent to the scale and duration of this conflict and its direct and indirect effects, it is not reasonably 
possible to estimate the impact such conflict will have on the global economy or on the economies of the countries in 
which we operate and, consequently, our business, financial condition and results of operations. 
Changes in U.S. trade and other policies under the Trump administration may adversely impact our 
business, financial condition, and results of operations. 
The administration of U.S. President Donald Trump has introduced significant changes in trade and 
regulatory policies, including tariffs, trade restrictions, and enforcement measures that could affect cross-border 
commerce and foreign business operations. On February 1, 2025, President Trump issued an executive order, 
effective March 4, 2025, imposing tariffs on imports from Canada, Mexico, and China, and made announcements 
regarding the potential imposition of tariffs on other jurisdictions. Furthermore, on April 2, 2025, President Trump 
announced that the United States would impose a 10% tariff on all countries, effective on April 5, 2025, and an 
individualized reciprocal higher tariff on countries with which the United States has the largest trade deficits. While 
certain energy products (such as crude oil) have been exempted, the effect on global economic growth and trade of 
these measures remains uncertain, and could disrupt global trade flows, and increase operational costs for companies 
reliant on international supply chains. 
 
As an oil and gas company operating in Mexico and Argentina, we are subject to import regulations, supply 
chain dependencies, and cross-border energy trade policies that could be affected by U.S. government actions. Any 
tariff increases, trade restrictions, or enforcement measures targeting the energy sector could increase costs, limit 
access to critical infrastructure and materials, and disrupt operational continuity.  
 
Additionally, the U.S. government has designated certain international cartels and transnational criminal 
organizations, including those operating in Mexico, as Foreign Terrorist Organizations (“FTOs”) and Specially 
Designated Global Terrorists (“SDGTs”). For more information, see “—Risks Related to the Argentine and Mexican 
Economic and Regulatory Environments—Economic and political developments in Mexico may adversely affect 
Mexican economic policy and, in turn, our operations.” 
 
Given the expanding scope of trade restrictions and the uncertainty surrounding future policies of the Trump 
administration, we can provide no assurances regarding the full extent of any potential impact on our operations. To 
the extent that changes in the political or regulatory environment due to the imposition of tariffs or other measures 

 
16 
 
negatively impact us or the markets in which we operate, our business, financial condition, and results of operations 
could be materially and adversely affected 
Our business requires significant and long-term capital investments and maintenance cost.  
The oil and gas industry is a capital-intensive industry. We make and expect to continue to make substantial 
capital expenditures related to development and acquisition of oil and gas resources and in order to maintain or 
increase the amount of our hydrocarbon reserves and production.  
We have funded, and we expect that we will continue to fund, our capital expenditures with cash generated 
by existing operations, debt, equity issuances and our available cash. However, under certain scenarios (e.g., in lower 
realized oil price scenarios compared to average realized oil prices prevailing as of the second semester of 2024), our 
financing needs may require us to alter or increase our capitalization substantially through the issuance of debt or 
equity securities or the sale of assets. We cannot guarantee that we will be able to maintain our current production 
levels, generate sufficient cash flow to pay for operating expenditures and service our financial debt, or that we will 
have access to sufficient borrowing or other financing alternatives to continue our exploration, exploitation and 
production activities at current or higher levels.  
Additionally, the incurrence of additional indebtedness would require that a portion of our cash flow from 
operations be used for the payment of interest and principal on our indebtedness, thereby reducing our ability to use 
cash flow from operations to fund working capital, capital expenditures, operating expenditures and acquisitions. The 
actual amount and timing of our future capital expenditures may differ materially from our estimates as a result of 
various factors. We may decrease our actual capital expenditures in response to lower commodity prices, which 
would negatively impact our ability to increase or even maintain production.  
If our revenues decrease, we may have limited ability to obtain the capital necessary to sustain our operations 
at current levels. If additional capital is needed, we may not be able to obtain debt or equity financing on terms 
acceptable to us, if at all. If cash flow generated by our operations are not sufficient to meet our capital requirements, 
the failure to obtain additional financing could result in a reduction of the capital expenditures devoted to the 
development of our assets, or even in a curtailment of our operations. This, in turn, could lead to a decline in 
production, and could materially and adversely affect our business, financial condition and results of operations, 
including our ability to service financial debt obligations, and the market value of our series A shares or ADSs.  
We may not be able to acquire, develop or exploit new reserves, which could decrease the volume of our 
reserves over time and could, in turn, adversely affect our financial condition and the results of our operations.  
The hydrocarbon reserves in any given reservoir decreases as such oil and gas volumes are produced and 
consumed, with the range of decrease depending on the characteristics of the reservoir and the production rate. 
Therefore, our results of operations largely depend on our ability to produce oil and gas from existing reserves, to 
discover additional oil and gas reserves, and to economically exploit oil and gas from these reserves. Unless we are 
successful in our exploration of oil and gas reserves and their development, in replacing our existing oil and gas 
reserves or in acquiring new reserves, the production of oil and gas and the volume of our total reserves will decrease 
over time. While we have geological reports evaluating certain proved and probable reserves, as well as contingent 
and prospective resources in our blocks, there is no assurance that we will continue to be successful in the 
exploration, appraisal, development and commercialization of oil and gas.  
Drilling activities are also subject to numerous risks and may involve unprofitable efforts, not only with 
respect to dry wells but also with respect to wells that are productive but do not produce enough net income to derive 
profit after covering drilling costs and other operating costs. The construction of a well does not assure a return on 
investment or recovery of the costs of drilling, completion and operating costs. Lower oil and natural gas prices could 
also affect our future investment and growth, including future and pending acquisitions.  
We may not be able to identify commercially exploitable reservoirs or implement our capital investment 
program to complete or produce more oil and gas reserves, and the wells we plan to drill may not result in the 
discovery or production of oil or natural gas. If we are unable to replace our production with new reserves, or acquire 
new reserves, our reserves will decline and our financial condition, results of operations, cash flow and market value 
of our series A shares and ADSs could be negatively affected. 

 
17 
 
The oil and gas reserves that we estimate are based on assumptions that could be inaccurate.  
Our oil and gas reserves are estimates based on certain assumptions that could be inaccurate. Reserve 
estimates depend on the quality of engineering and geological data at the date of the estimate and the manner in which 
they are interpreted. In addition, reserve engineering is a subjective process for estimating oil and gas accumulations 
that cannot be accurately measured, and the estimates of other engineers may differ materially. A number of 
assumptions and uncertainties are inherent in estimating the amounts of proven reserves of oil and gas (including, but 
not limited to production forecasts, the time and amount of development expenditures, testing and production after the 
date of the estimates, among others), many of which are beyond our control and are subject to change over time. 
Consequently, measures of reserves are not precise and are subject to revision. Any downward revision in 
our estimated quantities of proved reserves could adversely impact our financial condition and results of operations, 
and ultimately have a material adverse effect on the market value of our series A shares or ADSs. In addition, the 
estimation of “proved oil and natural gas reserves” based on SdE Resolution No. 324/2006 and Argentine Secretariat 
of Hydrocarbon Resources (Secretaría de Recursos Hidrocarburíferos) Resolution No. 69-E/2016 may differ from 
the standards required by SEC’s regulations. 
As a result, reserve estimates could be materially different from the amounts that are ultimately extracted, 
and if such amounts are significantly lower than the initial reserves estimates it could result in a material adverse 
effect on our financial performance, including our ability to service financial debt obligations, operating results and 
the market value of our series A shares and ADSs. See “Item 4—Information on the Company—Industry and 
Regulatory Overview—Oil and Gas Regulatory Framework in Argentina—Reserves and Resources Certification in 
Argentina” and the 2024 Reserves Report attached hereto as Exhibit 99.1. 
Our business operations rely heavily on our production facilities 
A material portion of our revenues depends on our oil and gas facilities, which are key to producing, 
transporting, treating and injecting oil and gas into transportation infrastructure for sale. In order to execute our 
strategic plan and meet our targets, we need to expand our capacity to transport, treat and inject our oil and gas 
production. If we are not able to execute these expansion projects, our growth plan could be affected.  
In addition, while we believe that we maintain adequate insurance coverage and appropriate security 
measures in respect of such facilities, any material damage to, accident at, or other disruption at such production 
facilities could have a material adverse effect on our production capacity, financial condition and results of 
operations. 
The lack of availability of midstream capacity may limit our possibility of increasing hydrocarbon 
production and may adversely affect our financial condition and results of operations.  
Our capacity to exploit our hydrocarbon reserves largely depends upon the availability of midstream 
infrastructure on commercially acceptable terms to transport the produced hydrocarbons from our oilfields to the 
markets in which they are sold. Typically, oil is transported by pipelines, trucks and tankers to refineries, and gas is 
usually treated, compressed and transported by pipeline to customers. The lack of oil transportation, storage or 
loading infrastructure, as well as the lack of vessels for maritime oil transportation, may adversely affect our financial 
condition and results of operations. The lack of gas treatment, compression or transportation infrastructure may also 
adversely affect our financial condition and results of operations.  
In particular, most of our crude oil production is transported from the Neuquina Basin through the Oldelval 
pipeline system to the south of the Province of Buenos Aires, from where it is sent to refineries or port facilities at 
Puerto Rosales for exports. On the other hand, part of our oil is transported to Chile through the Vaca Muerta Norte 
pipeline and the Trasandino pipeline. The export facilities at Puerto Rosales, owned by Oiltanking Ebytem, are 
operating at near full capacity, therefore, Oiltanking Ebytem is currently executing an expansion project, which is 
expected to be operational by the second quarter of 2025. Furthermore, VMOS (as defined below) plans to construct a 
new pipeline from Vaca Muerta to a new export terminal with storage capacity at Punta Colorada, Province of Río 
Negro, which is anticipated to become operational in 2027. 
We have secured sufficient oil midstream capacity through existing infrastructure and expansion projects to 
support the execution of our production growth plans in our Vaca Muerta assets. See “Item 4—Information on the 

 
18 
 
Company—Business Overview.” However, both planned events (such as scheduled maintenance) and unexpected 
disruptions (including adverse weather conditions, accidents, union strikes, explosions, or environmental incidents) 
may restrict access to existing oil midstream capacity, potentially limiting production and adversely impacting our 
financial condition and results of operations. 
Additionally, if oil midstream expansion projects are delayed or canceled, a potential lack of transportation 
capacity could constrain our production growth, affect our ability to meet targets, and negatively impact our future 
financial performance, including our ability to service financial debt obligations and the market value of our series A 
shares and ADSs. 
Developments in the oil and gas industry and other factors may result in substantial write-downs of the 
carrying amount of our assets, which could adversely affect our financial condition and results of operations.  
Changes in the economic, regulatory, business or political environment in Argentina, Mexico or other 
markets where we operate, such as price controls over crude oil or crude oil by-products or the significant decline in 
international crude oil and gas prices in recent years, among other factors, may result in the recognition of impairment 
charges in certain of our assets.  
We evaluate the carrying amount of our assets for possible impairment on an annual basis, or more 
frequently where the circumstances require. Our impairment tests are performed by a comparison of the carrying 
amount of an individual asset or a cash-generating unit with its recoverable amount. Whenever the recoverable 
amount of an individual asset or cash-generating unit is less than its carrying amount, an impairment loss is 
recognized to reduce the carrying amount to the recoverable amount. Substantial write-downs of the carrying amount 
of our assets could adversely affect our financial condition and results of operations.  
Exploration and development drilling may not result in commercially productive reserves.  
Drilling involves numerous risks, including the risk that no commercially productive oil or gas reservoirs 
will be encountered. The cost of drilling, completing and operating wells is often uncertain, and drilling operations 
may be curtailed, delayed or canceled, or become costlier, as a result of a variety of factors, including (i) unexpected 
drilling conditions; (ii) unexpected pressure or irregularities in formations; (iii) equipment failures or accidents; (iv) 
construction delays; (v) hydraulic stimulation accidents or failures; (vi) adverse weather conditions; (vii) restricted 
access to land for drilling or laying pipelines; (viii) title defects; (ix) lack of available gathering, transportation, 
processing, fractionation, storage, refining or export facilities; (x) lack of available capacity on interconnecting 
transmission pipelines; (xi) access to, and the cost and availability of, the equipment, services, resources and 
personnel required to complete our drilling, completion and operating activities; (xii) involuntary human error; and 
(xiii) delays imposed by or resulting from compliance with environmental and other governmental or regulatory 
requirements.  
Our future drilling activities may not be successful and, if unsuccessful, our proved reserves and production 
would decline, which could have an adverse effect on our future results of operations and financial condition. While 
all drilling, whether development, extension or exploratory, involves these risks, exploratory and extension drilling 
involves greater risks of dry holes or failure to find commercial quantities of hydrocarbons. If we are not successful in 
our exploration or extension drilling activities, we might not be able to replace the reserves consumed as a result of 
our production and therefore our production will decline over time, which could adversely affect our financial 
condition and results of operations. 
Our operations are substantially dependent upon the availability of water and our ability to dispose of 
produced water gathered from drilling and production activities. Restrictions on our ability to obtain water or 
dispose of produced water may have a material adverse effect on our financial condition, results of operations and 
cash flows.  
Water is an essential component of drilling, completion and hydrocarbon production activities. Limitations 
or restrictions on our ability to secure sufficient amounts of water (including limitations resulting from natural causes 
such as drought), could materially and adversely impact our operations. Severe drought conditions can result in local 
water districts taking steps to restrict the use of water in their jurisdiction for drilling and hydraulic stimulation in 
order to protect the local water supply. If we are unable to obtain water to use in our operations from local sources, it 
may need to be obtained from new sources and transported to drilling sites, or other facilities, resulting in increased 

 
19 
 
costs, which could have an adverse impact on our financial condition and cash flows. Additionally, if we were unable 
to obtain water from any sources, we might be forced to halt our drilling and completion activities, which could have 
a material adverse effect on our growth prospects, financial condition, results of operations and cash flows. 
Our operations may pose risks to the environment.  
Some of our operations are subject to environmental risks which could materialize unexpectedly and could 
have a material adverse impact on our financial condition and results of operations. These include the risk of leaks or 
spills of hydrocarbons, contamination of soil or water sources, fire and explosions, damages to infrastructure or the 
general population. There can be no assurance that future environmental issues will not result in cost increases, civil 
liability or administrative action, which could lead to a material adverse effect on our financial condition and results 
of operations. 
Any climate change legislation or regulations restricting GHG emissions could result in increased 
operating costs. 
Due to concern over the risk of climate change, a number of countries have adopted, or are considering the 
adoption of, new regulatory requirements to reduce greenhouse gas emissions, such as carbon taxes, increased 
efficiency standards or the adoption of cap-and-trade regimes. More stringent environmental regulations can result in 
the imposition of costs associated with GHG emissions, either through environmental agency requirements relating to 
mitigation initiatives, compliance costs and operational restrictions, and/or through other regulatory measures such as 
GHG emissions taxation and market creation of limitations on GHG emissions that have the potential to increase our 
operating costs. We expect that a growing share of our GHG emissions could be subject to regulation, resulting in 
increased compliance costs and operational restrictions. Regulators may seek to limit certain oil and gas projects or 
make it more difficult to obtain required permits for hydrocarbon E&P. Additionally, climate activists around the 
globe are challenging the grant of new and existing regulatory permits. We expect that these challenges are likely to 
continue and could delay or prohibit operations in certain cases. 
Compliance with legal and regulatory changes relating to climate change set out by the Argentine and 
Mexican governments, including those resulting from the implementation of international treaties (see “Item 4—
Information on the Company—Business Overview—Argentine Regulatory Framework in Connection with Climate 
Change”) may in the future increase our costs to operate and maintain our facilities, install new emission controls on 
our facilities and administer and manage any GHG emissions program. Revenue generation and strategic growth 
opportunities may also be adversely affected.  
In addition, environmental laws that may be implemented in the future could increase litigation risks and 
have a material adverse effect on us. For example, in 2019, the Argentine Congress enacted Law No. 27,520 on 
Minimal Standards on Global Climate Change Adaptation and Mitigation, which focused on implementing policies, 
strategies, actions, programs and projects that can establish responsibilities for gas emissions and prevent, mitigate or 
minimize the damages or impacts associated with climate change (see “Item 4—Information on the Company—
Business Overview—Argentine Regulatory Framework in Connection with Climate Change”). If additional 
requirements were adopted in Argentina, these requirements could add to our litigation costs and impact adversely on 
our results of operations. 
We cannot predict the overall impact that the enactment of new environmental laws or regulations could 
have on our financial results, results of operations, and cash flows and the market value of our series A shares and 
ADSs. 
The energy transition could result in reduced demand for the oil and gas we produce, negatively impact 
our long-term plans, and lead to opposition from certain stakeholders. 
We expect that measures taken by governments, NGOs, customers, and end users of refined hydrocarbon 
products to reduce emissions will continue to suppress demand for hydrocarbons and their by-products, potentially 
impacting oil and gas prices. For example, demand could decline further if households increasingly adopt electric 
vehicles, public transportation transitions to electric or renewable fuel sources, power generation shifts more 
extensively to renewable energy, or hydrogen and other green energy alternatives achieve widespread adoption. These 
developments may contribute to a decline in global oil and gas demand, potentially leading to additional asset 
provisions, lower earnings, project cancellations, reduced access to capital, and impairments of certain assets. 

 
20 
 
Regulations and regimes promoting alternative energy resources may also lead to a decline in demand for 
crude oil and natural gas, or any of their by-products, in the long-term. In addition, increased regulation of GHG 
emissions may create greater incentives for the use of alternative energy sources. Any long-term material adverse 
effect on the oil industry could adversely affect the financial and operational aspects of our business, which we cannot 
predict with certainty as of the date of this annual report. 
There are other risks associated with climate change, such as an increasing number of conflicts with 
landowners and local communities, difficulties in hiring and retaining staff, and increased difficulty accessing 
technology. Moreover, certain investors might decide to divest their investments in fossil fuel companies and different 
stakeholder groups might be included to exert pressure on commercial and investment banks to stop financing fossil 
fuel companies. According to press reports, in recent years some financial institutions have limited their exposure to 
fossil fuel projects. If this trend were to accelerate in the future, our ability to access financing for future projects may 
be adversely affected. These factors could have a negative impact on the demand for our products and services and 
may jeopardize or even impair the implementation and operation of our business, adversely impacting our operating 
and financial results and limiting our growth opportunities. 
Expectations relating to GHG emissions could expose us to potential liabilities, increased costs, and 
reputational harm. 
In 2021, we announced our ambition to become net zero in scope 1 and 2 GHG emissions by 2026. We plan 
to achieve this ambition through a multi-year plan to reduce our operational carbon footprint and the implementation 
of our own portfolio of NBS. Our NBS projects are designed to offset the residual emissions from our operations 
through carbon capture in soil and forest. See “Item 4—Information on the Company—Business Overview—
Environmental Policy.”   
Our net zero ambition is subject to complex methodologies, calculations, assumptions and estimates, 
including with respect to how we determine our emissions and the carbon offsets through our NBS projects. Although 
we believe that our methodologies, calculations, assumptions and estimates are reasonable, we cannot assure you that 
we will not revise our past emissions estimates, our carbon offsets or our future emissions projections or goals as a 
result of new developments, technologies, regulations, standards or otherwise. In addition, we may pursue business 
opportunities (including acquisitions or divestments of oil and gas assets) that may affect our emissions estimates and 
projections.  
Our emissions information (including carbon offsets) may be calculated differently than by other companies, 
including our competitors. Investors should make their own diligence and assessment on whether our emissions 
information is directly comparable to that of other companies. 
Our GHG emissions inventory is calculated and reported in compliance with industry recognized standards 
(GHG Protocol, API Compendium and GRI reporting). Such calculation is based on limited information and subject 
to significant uncertainties. For example, our emissions information excludes the emissions arising from concession 
areas that we do not operate in Argentina and from our operated asset in Mexico, and therefore only cover 
approximately 93% of our production, based on our 2024 performance data.  
Therefore, we cannot guarantee that our net zero ambition will be fully realized on the timeline we expect or 
at all. Any failure, or perceived failure, by us to adhere to our net zero ambition or other public statements, comply 
fully with developing interpretations of climate-related laws and regulations, or meet evolving and varied stakeholder 
expectations and standards could harm our business, reputation, financial condition, and operating results. 
If we fail to meet the pace and extent of society’s changing demands or our own aspirations for lower 
carbon energy as the energy transition unfolds (including failing to meet our aspiration to become net zero in 
scope 1 and 2 GHG emissions by 2026), we could face reputational costs or fail in sustaining and developing our 
business. 
The pace and extent of the energy transition could pose a risk to the company if our own progress towards 
decarbonization moves at a different speed than that of our competitors and the economy in general, or if we fail to 
meet our aspirations. If we are slower than competitors or the economy in general, either because we do not invest 
enough funds, or invest in technologies that fail to reduce our carbon footprint, or if we fail to meet our ambition to 
become net zero in scope 1 and 2 GHG emissions by 2026, our reputation may suffer and customers may prefer a 

 
21 
 
different supplier, which would adversely impact demand for our hydrocarbon products, including the market value of 
our shale oil acreage and associated resources we expect to develop in the future. Our failure to time the transition of 
our production to address climate-change related concerns could have a material adverse effect on our earnings, cash 
flows and financial condition. 
Adverse climate conditions may adversely affect our results of operations and our ability to conduct 
drilling operations. Additionally, adverse climate conditions could negatively impact the Argentine economy. 
The physical effects of climate change such as, but not limited to, heat waves, storms, hail, increases in 
temperature and sea levels, extensive droughts affecting the river basins where we operate, and fluctuations in sea 
levels could adversely affect our operations and supply chains. Such adverse climate conditions may lead to, among 
others, cost increases, drilling delays, power outages, production stoppages, and difficulties in transporting the oil and 
gas produced by us. Any decrease in our oil and gas production and sales could have a material adverse effect on our 
business, financial condition or results of operations.  
In addition, the occurrence of severe adverse weather conditions, especially droughts, hail, floods or frost or 
diseases, is unpredictable, may have a potentially devastating impact on production, mainly on agricultural products, 
and may adversely affect the supply and price of such products. Adverse weather conditions may be exacerbated by 
the effects of climate change. The effects of severe adverse weather conditions may reduce yields of agricultural 
activities in Argentina, which constitute a material share of GDP and exports. This could have an adverse effect on 
the economy, including lower inflows of hard currency from exports, depreciation of the local currency, rising 
inflation and poverty. 
Our activities are subject to social, reputational, and operational risks, including negative media attention, 
potential for protests by members of the local communities in the places where we operate, and seismic activity.  
Although we are committed to operating in a socially responsible manner, we may face opposition from 
local communities and negative media attention. For example, several of our operations are carried out in the 
Province of Neuquén, Argentina. Local communities, including indigenous communities, have engaged in various 
forms of protest against business activities in general, including oil and gas. Although we consider our relationship 
with local communities, including indigenous communities, to be good, we cannot ensure that any form of protest, 
including roadblocks, actions limiting access of our workers or contractors to our operations, sabotage, or any 
disruptive action will not impact our operations. Any such action could have an adverse effect on our reputation, 
financial condition, and results of operations. 
There is a risk that hydraulic stimulation activities during well completion operations in the Vaca Muerta 
may induce seismicity. Vista, together with a consortium of other oil and gas operators, has conducted extensive 
research into potential sources of increased seismic activity in the region. As of the date of this annual report, no 
conclusive evidence has been found linking produced water reinjection into geological formations with amplified 
seismicity. Nonetheless, Vista continues to evaluate potential contributing factors. Although as of the date of this 
annual report no seismic events have resulted in above-ground impacts affecting the health and safety of the 
communities in the region we operate, the growing density of hydraulic fracturing activities in the region may lead to 
increased seismic activity in the future. Any such increase could expose the company to heightened regulatory 
oversight or stakeholder concern. 
Furthermore, we are not currently aware of operations being conducted in areas of the Vaca Muerta occupied 
by indigenous communities. However, self-identification by indigenous communities in the region has historically 
been fluid, and this circumstance may change over time. In such cases, the Company may be required to enhance its 
engagement with indigenous communities and develop a dedicated engagement policy in accordance with Argentine 
law on prior consultation and International Labour Organization (ILO) Convention No. 169 on Indigenous and Tribal 
Peoples. Failure to adequately address these matters could expose us to additional regulatory, legal or reputational 
risks.  
Our industry has become increasingly dependent on digital technologies to carry out daily operations and 
is subject to increasing cybersecurity threats. 
As dependence on digital technologies has increased, cyber incidents, including deliberate attacks or 
unintentional events have also increased worldwide. Even if we have implemented, and continue to implement, a 

 
22 
 
cybersecurity plan (See “Item 16K—Cybersecurity”), the technologies, systems, and networks that we have 
implemented, or may implement in the future, and those of our service providers, may be the object of cyberattacks or 
failures to the security of information systems, which could lead to interruptions in critical industrial systems, the 
unauthorized disclosure of confidential or protected information, data corruption, other interruptions of, or disruptions 
to, our operations. In addition, certain cyber incidents, such as the advanced persistent threat, may not be detected for 
a prolonged period of time. Although we have adopted a Cybersecurity Policy that serves as an umbrella for our 
cybersecurity risk management standards and procedures to safeguard information and protect our systems, we cannot 
assure you that cyber incidents will not happen in the future and that our operations and/or our financial performance 
will not be affected.  
Information security risks have generally increased in recent years as a result of the proliferation of new 
technologies and the increased sophistication and activities of cyber-attacks. We depend on digital technology, 
including information systems to process financial and operating data, analyze seismic and drilling information and 
oil and gas reserves estimates. We have increasingly connected equipment and systems to the Internet. Because of the 
critical nature of their infrastructure and the increased accessibility enabled through connection to the Internet, they 
may face a heightened risk of cyber-attack. In the event of such an attack, they could have our oilfield operations 
disrupted, property damaged, and customer information stolen, experience substantial loss of revenues, response costs 
and other financial loss; and be subject to increased litigation and damage to their reputation. A cyber-attack could 
adversely affect our business, results of operations and financial condition. See “Item 16K—Cybersecurity.” 
Risks Related to our Company 
The historical financial information included in this annual report and the past performance and 
experience of our Executive Team may not be indicative of future results.  
Our business is inherently volatile due to the influence of external factors, such as domestic oil and gas 
demand, oil and gas prices, availability of financial resources for our business plan and its corresponding costs and 
government regulations. Our periodic operating results could fluctuate for many reasons, including many of the risks 
described in this section, which are beyond our control. Consequently, our past financial condition, results of 
operations and the trends indicated by such results and financial condition may not be indicative of current or future 
financial conditions, results of operations or trends. Additionally, we believe that the experience of our Executive 
Team constitutes a differentiated source of competitive strength for us. However, the experience of our Executive 
Team in the past (whether in Vista or in other companies) may not be indicative of our future results of operations. 
For more information regarding our historical consolidated condensed financial information, see “Presentation of 
Information,” “Item 8—Financial Information” and the Audited Financial Statements included elsewhere in this 
annual report.  
The results of our planned development programs in new or emerging shale development areas and 
formations may be subject to more uncertainties than programs in more established areas and formations and may 
not meet our expectations for reserves or production.  
The results of our horizontal drilling efforts in emerging areas and formations in Argentina such as in the 
Vaca Muerta formation in the Neuquina Basin are generally more uncertain than drilling results in areas that are more 
developed and have more established production. Because emerging areas and associated target formations have 
limited or no production history, we are less able to rely on past drilling results in those areas as a basis to predict our 
future drilling results. In addition, horizontal wells drilled in shale formations, as distinguished from vertical wells, 
utilize multilateral wells and stacked laterals, which could adversely impact our ability to maximize the efficiency of 
our horizontal wells related to reservoirs drainage over time. Further, access to adequate gathering systems or pipeline 
takeaway capacity and the availability of drilling rigs and other services may be more challenging in new or emerging 
areas, and can be particularly challenging in Argentina, where access to capital is generally more limited compared to 
other regions. If our drilling results are less than anticipated, or we are unable to execute our drilling program because 
of capital constraints, access to gathering systems and takeaway capacity or otherwise, and/or natural gas and oil 
prices decline, our investment in these areas may not be as economic as we anticipate, we could incur material write-
downs of unevaluated properties and the value of our undeveloped acreage could decline in the future.  

 
23 
 
Part of our strategy involves using some of the latest available horizontal drilling and completion 
techniques, which involve risks and uncertainties in their application.  
Our operations involve utilizing some of the latest drilling and completion techniques we have developed, 
along with those developed by our key service providers. Risks that we face while drilling horizontal wells include, 
but are not limited to, the following (i) landing the wellbore in the desired drilling zone; (ii) staying in the desired 
landing zone while drilling horizontally through the formation; (iii) running casing the entire length of the wellbore; 
and (iv) being able to run tools and other equipment consistently through the horizontal wellbore.  
Risks that we face while completing wells include, but are not limited to, the following: (i) the ability to 
stimulate the planned number of stages; (ii) the ability to run tools the entire length of the wellbore during completion 
operations; and (iii) the ability to successfully clean out the wellbore after completion of the final hydraulic 
stimulation stage.  
Any problems or failures in our drilling and completion techniques could adversely affect our business, 
results of operations and financial condition. 
Our operations and drilling activity are concentrated in areas of high competition such as the Neuquina 
Basin in Argentina, which may affect our ability to obtain the personnel, equipment, services, resources and 
facilities access needed to complete our development activities as planned or result in increased costs; such 
concentration also makes us vulnerable to risks associated with operating in a limited geographic area.  
As of December 31, 2024, most of our producing properties and total estimated proved reserves were 
geographically concentrated in Vaca Muerta, in the Neuquina Basin, located in Argentina. A substantial portion of 
our operations and drilling activity are concentrated in areas in such basins where industry activity is high. As a result, 
demand for personnel, equipment, power, services and resources may increase in the future, as well as the costs for 
these items. Any delay or inability to secure the personnel, equipment, power, services and resources could result in 
oil, NGL and gas production being below our forecasted volumes. In addition, any such negative effect on production 
volumes, or significant increases in costs, could have a material adverse effect on our results of operations, cash flow, 
profitability.  
As a result of this concentration, we may be disproportionately exposed to the impact of delays or 
interruptions of operations or production in this area caused by external factors such as governmental regulation, state 
politics, market limitations, water or sand shortages, lack of midstream capacity, or extreme weather-related 
conditions.  
The oil and gas industry is competitive and our ability to achieve our strategic objectives and expand our 
business depends on our ability to successfully compete in the market and react to competitive forces. 
The oil and gas industry is competitive and we compete with the major independent and state-owned oil and 
gas companies engaged in the E&P sector that possess substantially greater financial and other resources than we do 
for researching and developing E&P technologies, accessing markets, equipment, midstream capacity, labor and 
capital required to acquire, develop and operate our properties, as well as political relationships and connections with 
other stakeholders, which is key, given that our business and assets are subject to political decisions. We also compete 
for the acquisition of licenses and properties in the countries in which we operate.  
Should we choose to bid for exploration or exploitation rights in a hydrocarbon area, or bid for midstream 
capacity, we would face significant competition from state-owned, private and publicly-traded companies. 
As we operate in a very competitive business, our competitors may be able to pay more for productive oil 
and natural gas properties and exploratory prospects and to evaluate, bid for and purchase a greater number of 
properties and prospects than our financial or personnel resources permit. Our competitors may also be able to offer 
better compensation packages to attract and retain qualified personnel than we are able to offer. In addition, there is 
substantial competition for capital available for investment in the oil and natural gas industry. As a result of each of 
the foregoing, we may not be able to compete successfully in the future in acquiring prospective reserves, developing 
reserves, marketing hydrocarbons, attracting and retaining quality personnel or raising additional capital, which could 

 
24 
 
have a material adverse effect on our business, financial condition or results of operations. See ”Item 4—Information 
on the Company—Business Overview—Customers and Marketing—Competition.” 
We are also affected by competition for drilling rigs and the availability of related equipment, leading to 
higher drilling costs over the past several years. Higher commodity prices generally increase the demand for drilling 
rigs, supplies, services, equipment and crews, and can lead to higher costs of oilfield services, or shortages of drilling 
equipment, services and personnel. Additionally, the Argentine Foreign Exchange Regulations generate barriers to 
entry for international service providers, limiting the supply of oilfield goods and services in Argentina. See “Item 
10—Additional Information—Exchange Controls.” Accordingly, failure to manage our costs and our operational 
performance could result in a material adverse effect on our earnings, cash flows and financial condition.  
We must achieve certain milestones to protect the exploitation rights in our concessions. 
In order to keep our exploitation rights in our concessions, we must achieve certain milestones, including 
investment commitments related to drilling and production in determined time periods, as stated in the relevant 
agreements signed with government authorities. Operating and maintenance costs may increase significantly due to 
adverse local or international market conditions, including local recession, foreign exchange volatility or high 
financing costs, which could prevent us from meeting our commitments under such agreements on commercially 
reasonable terms or at all, which may force us to forfeit our interests in such areas.  
If we do not succeed in meeting these milestones, renewing our agreements, maintaining our operations in 
these concessions or securing new ones, our ability to grow our business may be materially affected. See “Item 5.B 
Liquidity and Capital Resources—Other Contractual Obligations—Capital Expenditures” and “Item 5.A Operating 
Results—Factors Affecting our Results of Operations—Contractual Obligations.” 
We may fail to fully identify problems with any properties we acquire, and as such, assets we acquire may 
prove to be worth less than we paid because of uncertainties in evaluating recoverable reserves and potential 
liabilities.  
We might seek to acquire additional acreage in Vaca Muerta, Argentina, and more broadly in Latin America. 
Successful acquisitions require an assessment of a number of factors, including estimates of recoverable reserves, 
exploration potential, future oil and natural gas prices, adequacy of title, operating and capital costs and potential 
environmental and other liabilities. Although we conduct a review of the properties we acquire which we believe is 
consistent with industry practices, we can give no assurance that we have identified or will identify all existing or 
potential problems associated with such properties or that we will be able to mitigate any problems we do identify. 
Such assessments are inexact, and their accuracy is inherently uncertain. In addition, our review may not permit us to 
become sufficiently familiar with the properties to fully assess their deficiencies and capabilities. We do not inspect 
every existing well in the properties we acquire. Even when we inspect a well, we do not always discover structural, 
subsurface, title and environmental problems that may exist or arise. We are generally not entitled to contractual 
indemnification for preclosing liabilities, including environmental liabilities. We may acquire interests in properties 
on an “as-is” basis, with limited remedies for breaches of representations and warranties. As a result of these factors, 
we may not be able to acquire oil and natural gas properties that contain economically recoverable reserves or be able 
to complete such acquisitions on acceptable terms.  
We are exposed to foreign exchange risks related to our operations in Argentina.  
Our results of operations are subject to foreign exchange fluctuation of the Argentine Peso against the 
U.S. Dollar or other currencies, which could adversely affect our business and results of operations. The value of the 
Argentine Peso has experienced significant fluctuations in the past. The main effect of a depreciation or devaluation 
of the Argentine Peso against the U.S. Dollar would be on our realized crude oil prices of sales to the domestic 
market, given that gasoline prices in Argentina are denominated in local currency, so significant changes in exchange 
rate have historically limited the ability of refiners to pass through such changes to the end-users.  
Additionally, given several accounting rules, material changes in the value of the Argentine Peso against the 
U.S. Dollar may also negatively affect: (i) deferred income tax associated with our fixed assets, (ii) current income 
tax and (iii) foreign exchange differences associated with our Argentine Peso exposure. 

 
25 
 
A significant appreciation of the Argentine Peso against the U.S. Dollar or other currencies could increase 
the cost of expenditures that are contractually denominated and indexed in Argentine Pesos when translated into U.S. 
Dollars in the Company’s financial statements. This, in turn, could adversely affect the Company’s operating margins 
and financial performance, including its ability to service financial debt obligations. 
The exchange rate of the Argentine Peso against the U.S. Dollar and other currencies is beyond the 
Company’s control and is influenced by monetary and economic policies adopted by the Argentine government, as 
well as by the policies of other countries, particularly those of the United States and other key trading partners of 
Argentina. The Company cannot predict whether, or to what extent, the Argentine Peso will depreciate or appreciate 
against the U.S. Dollar or other currencies, nor can it determine the potential impact of such fluctuations on its 
business and financial condition.  
We may be subject to unknown or contingent liabilities related to our recent and future acquisitions. 
We occasionally conduct assessments of opportunities to acquire additional oil and gas assets and 
businesses. Any prospective acquisition could prove to be a substantial undertaking in terms of scale and may 
introduce new and potentially significant risks, including those related to political, financial, and geographical factors. 
The success of our acquisition activities is contingent upon our capacity to identify suitable candidates, negotiate 
acceptable terms of acquisition, and integrate their operations in an effective manner. 
Any prospective acquisition would be accompanied by a number of risks, including the potential for a 
significant decline in oil and gas prices, the risk that oil and natural gas reserves acquired may not be developed as 
anticipated, the difficulty of assimilating the operation and staff, the possible disruption of our ongoing business, the 
potential loss of significant key employees, and management’s inability to maximize our financial and strategic 
position through the successful integration of acquired assets and businesses. Additional challenges may include the 
maintenance of uniform standards, control, procedures and policies, and the deterioration of relationships with 
employees, customers, and contractors as a result of any integration of new management personnel. 
Moreover, additional capital may be required to finance an acquisition, which could entail debt financing and 
expose the Company to leverage risk. Any acquisition could impact our liquidity, particularly if we use a portion of 
available cash to finance the acquisition, and may impact our ability to service financial debt obligations. 
There can be no assurance that we will be able to overcome these risks or any other issues related to these 
acquisitions. Unexpected costs and challenges may arise, and we may experience delays in realizing the benefits of an 
acquisition. Our capitalization and operational results may undergo significant changes, and we may not have the 
opportunity to thoroughly assess the economic, financial, and other pertinent information necessary for evaluating 
future acquisitions. If we cannot effectively manage the integration of acquisitions, it could reduce our focus on 
subsequent acquisitions and current operations, potentially impacting our financial results, reputation, and business. 
In the event of an accident or other occurrence which is not covered by our insurance policies, we may 
suffer significant losses which may have a material adverse effect on our business and results of operations.  
Even though we consider that we have insurance coverage consistent with international standards, there is no 
assurance concerning the availability or sufficiency of insurance coverage with respect to a particular loss or risk. In 
the event of an accident or other occurrence in our business which is not covered by insurance under our policies, we 
may suffer significant losses or be forced to provide compensation in a substantial amount from our own resources, 
which could have a material adverse effect on our financial condition.  
We are not concessionaires or operating partners in all of our joint ventures, as a result must rely on the 
activities of our operating partners in such joint ventures. Actions taken by the concessionaires and/or operators in 
these joint ventures could have a material adverse effect on our success.  
Both we and our subsidiaries carry out hydrocarbon E&P activities through unincorporated joint ventures 
entered into through agreements with third parties (joint operations for accounting purposes). In some cases, these 
joint venture agreements or our joint venture partners, rather than us, hold the rights to the concession or the E&P 
license contracts. Pursuant to the terms and conditions of such agreements, one of the parties assumes the role of 
operator, and therefore assumes the responsibility of executing all activities pursuant to the agreement. However, in 

 
26 
 
certain cases, neither we nor our subsidiaries may be able to assume the role of concessionaire and/or operator and, in 
such cases, we must rely on the measures taken by and the performance of our operating partners. Such actions could 
adversely affect our financial condition and our operating results. For example, as of December 31, 2024, we were not 
the operator of the Entre Lomas Neuquén, Acambuco, Entre Lomas Río Negro, Jarilla Quemada, Charco del 
Palenque, Jagüel de los Machos and 25 de Mayo–Medanito SE concessions, located in Argentina. In such cases, we 
would be subject to risks related to the performance of, and the measures taken by, the concessionaire and/or operator 
to carry out the activities. Such actions could adversely affect our financial condition and operating results. For a 
more complete description of our non-operated concessions, see “Item 4—Information on the Company—Business 
Overview—Argentina—Concessions.” 
We face risks related to certain legal proceedings.  
We may be parties to labor, commercial, civil, tax, criminal, environmental and administrative proceedings 
that, either alone or in combination with other proceedings, could, if resolved in whole or in part adversely to us, 
result in the imposition of material costs, fines, judgments or other losses. While we believe that we have provisioned 
such risks appropriately based on the opinions and advice of our external legal advisors and in accordance with 
applicable accounting rules, certain loss contingencies, particularly those relating to environmental and tax matters, 
are subject to change as new information develops and it is possible that losses resulting from such risks, if 
proceedings are decided in whole or in part adversely to us, could significantly exceed any accruals we have provided.  
As of December 31, 2024, we employed third-party employees under contract, mostly with large domestic 
and international service providers. Although we have policies regarding compliance with labor and social security 
obligations for our contractors, we can provide no assurance that the contractors’ employees will not initiate legal 
actions against us seeking indemnification based upon a number of Argentine judicial labor court precedents that 
established that the ultimate beneficiary of employee services is joint and severally liable with the contractor, which is 
the employee’s formal employer. 
In addition, we may be subject to undisclosed liabilities related to labor, commercial, civil, tax, criminal, 
environmental or other contingencies incurred by businesses we acquire in the future as part of our growth strategy, 
that we were not or may not be able to identify or that may not be adequately indemnified under our acquisition 
agreements with the sellers of such businesses, in which case our reputation, business, financial condition and results 
of operation may be materially and adversely affected.  
We are subject to Mexican, Argentine and other nations’ anti-corruption, anti-bribery, anti-
money laundering and economic sanctions laws and regulations. Our failure to comply with these laws could 
result in penalties, which could harm our reputation and have an adverse effect on our reputation, business, 
financial condition and results of operations.  
The United States Foreign Corrupt Practices Act of 1977, the United Kingdom Bribery Act 2010, the laws 
and regulations implementing the Organization for Economic Co-Operation and Development Anti-Bribery 
Convention, the Mexican Administrative Responsibilities Law (Ley General de Responsabilidades Administrativas), 
the Argentine Corporate Criminal Liability Law (Ley de Responsabilidad Penal Empresaria) and other applicable 
anti-corruption laws in other relevant jurisdictions prohibit companies and their intermediaries from offering or 
making improper payments (or giving anything of value) to government officials and/or persons in the private sector 
for the purpose of influencing them or obtaining or retaining business and require companies to keep accurate books 
and records and maintain appropriate internal controls.  
In particular, the Argentine Corporate Criminal Liability Law establishes the criminal liability of legal 
entities for offenses against public administration and transnational bribery committed by, among others, their legal 
counsel, directors, managers, employees or representatives. Under this law, a legal entity may be held liable—and 
subject to penalties including fines and partial or total suspension of activities—if it is proven that such offenses were 
committed, directly or indirectly, in its name, on its behalf or for its benefit. Moreover, if the Company obtained or 
could have obtained a benefit from such offenses, and if they resulted from a failure to implement effective controls, 
the Company may be held liable.  
It may be possible that, in the future, reports may emerge alleging instances of unethical and illegal conduct 
on the part of former agents, current or former employees or others acting on our behalf or on the part of public 

 
27 
 
officials or other third parties doing or considering business with us. While we will endeavor to monitor such reports 
and investigate matters which we believe warrant an investigation in keeping with the requirements of our compliance 
program, and, if necessary or appropriate make disclosure and notify the relevant authorities, any fines, other 
penalties or adverse publicity that such allegations may attract may have a negative impact on our business and 
reputation and lead to increased regulatory scrutiny of our business practices.  
If we or people or entities that are or were related to us are responsible for violations of applicable anti-
corruption laws (whether due to our own acts or inadvertence, or due to the acts or inadvertence of others) or the Code 
of Ethics and Conduct, we or other persons or entities related to us could suffer civil, criminal and/or other penalties, 
which in turn could have a material adverse impact on our future business, financial condition and results of 
operations. See “Item 16B—Code of Ethics.”  
We rely on key third-party suppliers, vendors and service providers to provide us with parts, components, 
services and critical resources that we need to operate our business.  
Companies operating in the energy industry, specifically the oil and gas sector, commonly rely upon various 
key third-party suppliers, vendors and service providers to provide them with parts, components, services, drilling 
rigs, completion sets, midstream capacity and other critical resources, needed to operate and expand their business. If 
these key suppliers, vendors and service providers fail to deliver, or are delayed in delivering, equipment, service rigs, 
completion sets, midstream capacity or critical resources, we may not meet our operating targets in the expected time 
frame, which could have an adverse effect on our business, financial condition, results of operations, cash flows 
and/or prospects.  
Our operations in the industry could be susceptible to the risks of performance, product quality and financial 
conditions of our key suppliers, vendors and service providers. For instance, their ability to adequately and timely 
provide us with parts, components, services and drilling rigs, completion sets, midstream capacity and resources 
critical to our operations may be affected if they are facing financial constraints or times of general financial stress 
and economic downturn. There can be no assurance that we will not encounter supply disruptions in the future or that 
we will be able to timely replace such suppliers or service providers that are not able to meet our needs, which might 
adversely affect a successful execution of our operations, and consequently, our business, financial condition, results 
of operations, cash flows and/or prospects.  
We employ a highly unionized workforce and could be subject to labor actions such as strikes, which 
could have a material adverse effect on our business.  
The sectors in which we operate are highly unionized. We cannot assure you that we or our subsidiaries will 
not experience labor disruptions or strikes in the future, which could result in a material adverse effect on our business 
and returns. 
In addition, we cannot assure you that we will be able to negotiate new collective bargaining agreements on 
the same terms, or on terms that are substantially similar, as those currently in force or that we will not be subject to 
strikes or labor interruptions before or during the negotiation process of said agreements. The collective bargaining 
agreement for the period April 2024 to March 2025 was signed on June 5, 2024, and amended by the agreement 
signed on October 30, 2024. In the future, if we are unable to renegotiate the collective bargaining agreement on 
satisfactory terms or are subject to strikes or labor interruptions, our results of operations, financial condition and the 
market value of our shares could be materially affected.  
Our performance is largely dependent on recruiting and retaining key personnel.  
Our current and future performance and business operations depend on the contributions of our Executive 
Team, and of our first-line managers, our engineers, technical crew and other employees. We rely on our ability to 
attract, train, motivate, and retain qualified and experienced administrative staff and specialists. No assurance can be 
given that we will be able to attract and retain personnel for key positions and replacing any of our key employees 
could prove difficult and time-consuming. The loss of the services and experience of any of our key employees, or 
our inability to recruit a suitable replacement or additional staff, could have a material adverse effect on our financial 
condition and operating results.  

 
28 
 
Risks Related to the Argentine and Mexican Economic and Regulatory Environments 
Our business is largely dependent on economic and political conditions in Argentina.  
Substantially all our operations and properties are located in Argentina. As a result, our business is largely 
dependent on the economic and political conditions prevailing in Argentina. Changes in economic, political, and 
regulatory conditions, as well as measures taken by the Argentine government, can have a significant impact on our 
operations and financial condition.  
Argentine economic conditions depend on various factors, including: (i) balance of trade and, in particular, 
the international prices of major exported commodities, (ii) stability and competitiveness of the Argentine Peso 
against foreign currencies, (iii) competitiveness and efficiency of domestic industries and services, (iv) levels of 
domestic consumption, investment, and local and international financing, (v) consumer price and wholesale price 
inflation levels, (vi) changes in economic or fiscal policies implemented by the Argentine government, (vii) labor 
conflicts and strikes, (viii) the fiscal expenditure by the Argentine government and its ability to maintain fiscal 
balance, (ix) interest rates and wage and/or price controls, and (x) the level of unemployment, political instability, and 
social tensions. 
Furthermore, the Argentine economy is particularly sensitive to fluctuations in the local political landscape. 
Legislative elections take place in Argentina every two years, resulting in the partial renewal of both chambers of 
Congress. The next legislative election is scheduled for October 2025. The outcome of these elections may lead to 
changes in government policies that could impact our business. We cannot assure whether such changes will occur or 
estimate their timing or potential effects on our operations and financial condition.  
On December 10, 2023, Javier Milei took office as President of Argentina and pledged to implement 
significant economic reforms. Following his inauguration, the Argentine Executive Branch enacted Decree No. 
70/2023, introducing measures aimed at reducing the size of the public administration, cutting public expenses, and 
deregulating the economy. On June 28, 2024, the Argentine Congress approved the Ley de Bases, which formally 
declares a state of public emergency in matters of administration, the economy, finance, and energy for one year, 
granting the Argentine Executive Branch a series of legislative powers. The Ley de Bases also introduced legal, 
institutional, and tax reforms affecting various sectors of the economy, including amendments to the Argentine 
Hydrocarbons Law. See “Item 4—Information on the Company—Industry and Regulatory Overview— Oil and Gas 
Regulatory Framework in Argentina—Ley de Bases.” 
The amendments to the Argentine Hydrocarbons Law include: (i) building on the self-sufficiency paradigm 
of the Argentine Hydrocarbons Law to include maximization of economic profits, in order to foster new investments; 
(ii) the principle of non-intervention in hydrocarbon or refined product prices by the Argentine government; and (iii) 
the principle of freedom of oil and gas exports. This latter principle is subject to objection by the SdE on technical 
and economic grounds. In addition, the amendments introduced other changes, including limiting subsequent 
renewals of concessions, granting more discretionary powers to Provinces in setting royalties, expanding activities to 
include hydrocarbon processing, and introducing more flexible requirements for obtaining transportation 
authorizations. 
Furthermore, on June 28, 2024, the Lower House of the Argentine Congress provided definitive approval for 
a fiscal reform (“Argentine Fiscal Reform”), successfully reincorporating the chapter on income tax and personal 
assets, previously rejected by the Argentine Senate. The Argentine Fiscal Reform was enacted and published in the 
Argentine Official Gazette (Boletín Oficial de la República Argentina) on July 8, 2024, effective from that date 
forward.  
It is difficult to predict the social, political, or economic impact of the measures announced and implemented 
by the Argentine government as of the date of this annual report, as well as any future measures that may be 
introduced, and the outcome of the ambitious deregulation plan, which the Argentine Executive Branch intends to 
implement through Decree No. 70/2023, the Ley de Bases, and/or the Argentine Fiscal Reform. These measures could 
affect our financial situation and the results of our operations. 
On August 22, 2024, the Argentine Congress approved a bill aimed at increasing public pensions. 
Subsequently, on September 12, 2024, the Argentine Congress approved another bill to increase funding for national 

 
29 
 
public universities. However, President Milei vetoed both laws, issuing Decree No. 782/2024 on September 2, 2024, 
for the public pensions bill, and Decree No. 879/2024 on October 2, 2024, for the university funding bill, citing the 
failure of both bills to identify the fiscal resources needed to cover the additional expenditures. Since the current 
administration took office, its limited representation in the Argentine Congress has constrained its ability to promote 
or block legislation, requiring negotiations with the opposition on various aspects of each bill to secure their support. 
Concurrently, certain circumstances have led the opposition to unite and advance laws that the administration had 
previously publicly opposed. This political dynamic and the current administration’s lack of majorities in the 
Argentine Congress could lead to a situation where vetoes by the Executive are frequently used for various projects 
approved by the Argentine Congress, thereby creating political uncertainty and legal claims, thus affecting 
predictability and the Argentine investment climate in general. We cannot predict how this situation will evolve and 
whether it may negatively impact our operations and/or financial conditions. 
Additionally, the Argentine economy is vulnerable to adverse events affecting its main trading partners. A 
continued deterioration of economic conditions in Brazil, Argentina’s main trading partner, and a deterioration of the 
economies of other important trading partners of Argentina, such as China or the United States, could have a 
significant adverse impact on Argentina’s trade balance and adversely affect Argentina’s economic growth, and 
therefore, could negatively impact our financial health and operating results. Furthermore, an increase in tariffs 
imposed on Argentine exports by Argentina’s most relevant trading partners, such as China, Brazil or the United 
States, or a significant depreciation of the currencies of our trading partners or competitors may negatively affect 
Argentina’s competitiveness and trade balance, and, consequently, negatively impact Argentina’s economic and 
financial condition and the results of our operations. See “Risks Related to Our Business and Industry—Changes in 
U.S. trade and other policies under the Trump administration may adversely impact our business, financial condition, 
and results of operations.” 
Also, see “Item 4—Information on the Company—Industry and Regulatory Overview— Oil and Gas 
Regulatory Framework in Argentina—Ley de Bases.” 
Argentina’s ability to obtain financing from international markets is limited, which could affect its 
capacity to foster economic growth. 
Over the past few years, Argentina has experienced financial distress, which has led to an increase in public 
debt. On January 28, 2022, the Argentine government and the International Monetary Fund (“IMF”) reached a 
consensus on pivotal policies as part of their ongoing discussions within the framework of an IMF-supported 
financing program. On March 17, 2022, the Argentine government approved an agreement with the IMF for a period 
of 30 months (“IMF Agreement”) to refinance US$44.0 billion of debt incurred between 2018 and 2019 under a 
stand-by agreement that was originally scheduled to be paid between 2021 and 2023. The IMF Agreement comprises 
ten quarterly reviews over a two-and-a-half-year period, with the objective of ensuring that the Argentine government 
complies with the targets set for each review period. Following each review, disbursements are made available. The 
repayment period for each disbursement is ten years, with a grace period of four and a half years, commencing in 
2026 and concluding in 2034. On June 13, 2024, the IMF concluded its eighth review, after which the IMF disbursed 
approximately US$800 million to the Argentine government to support economic recovery, and rebuild fiscal and 
external reserves. As of the date of this annual report, the IMF has disbursed a total of over US$41.4 billion to the 
Argentine government in accordance with the terms of the IMF Agreement. On January 10, 2025, the IMF conducted 
an ex-post evaluation (“EPE”) of Argentina’s exceptional access under the IMF Agreement, which expired at the end 
of 2024. The EPE report concluded that the program’s design did not fully account for the scale of Argentina’s fiscal 
and balance of payments challenges, given the country’s complex economic conditions, the post-COVID recovery 
environment, and difficulties in securing government commitment to the program’s objectives. On March 11, 2025, 
the Argentine Executive Branch issued Decree No. 179/2025, approving a new 10-year agreement (“Extended 
Facilities Program”) to be entered into with the IMF. The primary purpose of the Extended Facilities Program is to 
refinance liabilities, including non-transferable treasury bills and the remaining amounts pending amortization under 
the current IMF Agreement. On March 19, 2025, the lower house of the Argentine Congress ratified Decree No. 
179/2025, thereby giving final approval to the Extended Facilities Program. As of the date of this annual report, the 
Extended Facilities Program has not been executed. 
We cannot assure that the Argentine government will meet the targets of the upcoming reviews of the IMF. 
Moreover, we cannot assure that the IMF’s conditions will not affect Argentina’s ability to implement reforms and 

 
30 
 
public policies and boost economic growth. We also cannot predict the impact of the implementation of the IMF 
Agreement on Argentina’s (and indirectly our) ability to access the international capital markets. 
Despite the restructuring of Argentina’s public debt carried out between 2020 and 2023, international 
markets remain cautious with regards to Argentina’s debt sustainability and, as a result, country risk indicators remain 
high. In 2024, Argentina saw a decrease in country risk and an improvement in its sovereign debt rating. However, 
there can be no assurance that Argentina’s credit ratings will not be downgraded, suspended or cancelled in the future. 
Any downgrade, suspension or cancellation of Argentina’s sovereign debt rating may have an adverse effect on the 
Argentine economy and our business. 
Without renewed access to the financial markets, the Argentine government may not have the financial 
resources to drive growth. In addition, Argentina’s inability to obtain credit in international markets could have a 
direct impact on our ability to access those markets to finance our operations and growth, including the financing of 
capital expenditures, which would adversely affect our financial condition, results of operations and cash flows. In 
addition, we cannot predict the outcome of any future restructuring of Argentine sovereign debt. We have investments 
in Argentine sovereign bonds in the amount of US$8.7 million as of December 31, 2024. Any new event of default by 
the Argentine government could adversely affect their valuation and repayment terms, as well as have a material 
adverse effect on the Argentine economy and, consequently, our business and results of operations. 
Our operations are subject to extensive and evolving regulations in the countries in which we operate.  
The oil and gas industry is subject to extensive regulation by federal, state, provincial and local governments 
in the jurisdictions where we operate. The Argentine and Mexican hydrocarbons industries are highly regulated by 
federal, provincial, and municipal governments, covering various aspects, including the award of exploration permits 
and exploitation concession, production and export restrictions, taxation, price controls, domestic market supply 
obligations and environmental matters. As a result, our business is significantly influenced by regulatory and political 
conditions prevailing in the countries in which we operate, as described below, and our results of operations may be 
materially and adversely affected by regulatory and political changes in these countries.  
We cannot assure that changes in applicable laws and regulations, or adverse judicial or administrative 
interpretations of such laws and regulations, will not adversely affect the results of our operations. Similarly, we 
cannot assure you that future government policies, in the countries where we currently operate or might operate in the 
future, will not adversely affect the oil and gas industry.  
Additionally, we cannot provide assurances that our oil and gas concessions will be extended in the future as 
a result of the review by the controlling entities regarding the investment plans presented for analysis or that 
additional requirements to obtain extensions of permits and concessions will not be imposed.  
Moreover, we cannot provide assurances that the taxes, royalties and fees that regulate the oil and gas 
industry will not be increased in the future by municipal, provincial or federal governments, which could adversely 
affect our results of operations and financial condition, including our ability to service financial debt obligations. 
There is also no assurance that regulations or taxes (including royalties) enacted by provincial or municipal 
governments will not conflict with federal law and regulations, and that such taxes or regulations will not adversely 
affect our results of operations or financial condition. 
The Argentine and Mexican governments retain the authority to design and implement energy policies, 
which have previously included export restrictions, price controls, production incentives, and preferential policies for 
state-owned enterprises. In Argentina, the Argentine government has established in the past export restrictions on the 
free disposition of hydrocarbons and export proceeds, imposed duties on exports, and imposed price agreements 
among producers and refiners or create fiscal incentive programs to promote increased production. In Mexico, the 
Mexican government has pursued policies to increase state control over the energy sector, benefiting Pemex and CFE. 
Additionally, Pemex is the sole offtaker of our oil and gas production from CS-01, our asset in Mexico. In 
the past, we have experienced delays in collecting the proceeds from these sales from Pemex. Even if we diligently 
monitor and manage this issue to ensure timely collection, this problem could continue going forward, and even 
worsen, which could stress the financial position of our Mexican operations. 

 
31 
 
Any such controversies, limitations or export restrictions or any other measures imposed by Argentine or 
Mexican authorities could have a material adverse effect on our future business, financial condition, results of 
operations, cash flows and/or prospects and as a consequence, the market value of our series A shares or ADSs may 
decline. 
Measures adopted by the antitrust authority in Mexico could have a material adverse effect on our results 
and financial condition. 
The COFECE is the antitrust authority in Mexico with jurisdiction over a number of sectors of the Mexican 
economy, including the oil and gas sector, and as such, has jurisdiction over the activities conducted by Vista. The 
Mexican government has granted COFECE broad powers to investigate and prosecute absolute monopolistic practices 
(cartel activity), relative monopolistic practices (abuse of dominance) and illegal concentrations, as well as to prevent 
concentrations which could have anticompetitive effects. Additionally, COFECE can determine the existence of 
essential facilities and regulate their access and identify barriers to entry and issue recommendations to federal, local 
and municipal authorities to eliminate such barriers and encourage competition. Therefore, many of our activities may 
be reviewed by COFECE and, in the case of equity transactions involving certain monetary and ownership thresholds, 
we may be required to notify COFECE of our intent to enter into such transactions and the consummation of such 
transactions may be subject to COFECE’s authorization in accordance with applicable Mexican laws. As a result, the 
closing of pending or future acquisitions of assets or common shares in the Mexican market may be subject to the 
satisfaction or waiver of customary closing conditions, including, among others, the authorization of COFECE. 
Completion of such transactions is not assured, and they will be subject to risks and uncertainties, including the risk 
that the necessary regulatory approvals are not obtained or that other closing conditions are not satisfied. If such 
transactions are not completed, or if they are otherwise subject to significant delays, it could negatively affect the 
trading prices of our common shares and our future business and financial results.  
Further, COFECE might decide to impose penalties or establish conditions on our business if we are unable 
to request or receive, or are delayed in requesting or receiving, the aforesaid authorizations and, if these were to 
materialize, such claims could have a material adverse effect on our results and financial condition. Similarly, it 
cannot be guaranteed that the authorizations that have not been obtained can be obtained or can be obtained without 
conditions. Failure to obtain those authorizations, or the conditions to which they may be subject, could have a 
material adverse effect on our results and financial condition.  
Moreover, on December 20, 2024, Mexican President Claudia Sheinbaum published a constitutional reform 
in the Mexican Federal Official Gazette (Diario Oficial de la Federación), providing for the dissolution of various 
entities, including COFECE, CRE and CNH. For additional context on the regulatory changes in Mexico concerning 
CRE and CNH, see “Item 4—Information on the Company—Industry and Regulatory Overview—Oil and Gas 
Regulatory Framework in Mexico.” The reform anticipates that COFECE’s current functions will be transferred to a 
new authority. However, it will take effect 180 days after the Mexican Congress enacts new secondary legislation on 
economic competition or amends the existing competition law. Until such legislation is enacted, its impact on the oil 
and gas industry remains uncertain. 
Investors may be faced with risks inherent to investing in a company operating in stand-alone and 
emerging markets, such as Argentina and Mexico, including significant political, legal and economic risks, as well 
as risks related to fluctuations in the global economy.  
According to MSCI Inc, Argentina and Mexico are stand-alone and emerging market economies, 
respectively. As per the MSCI Global Market Accessibility Review, while nations classified as emerging markets are 
developing countries with potential growth in their economies, trade relations with other countries, stability of 
institutional framework, equal rights to foreign investors and low levels of capital flow restrictions, countries 
classified as stand-alone markets are those that are currently partially or fully closed to foreign investors, with small 
capital markets and political tensions. 
 
Investing in such markets generally carries inherent risks such as political, social and economic instability 
that may affect economic results, which may stem from many factors, including but not limited to, the following: high 
interest rates; abrupt changes in currency values; high levels of inflation; exchange controls; wage and price controls; 
regulations to import equipment and other necessities relevant for operations; changes in governmental economic, 

 
32 
 
administrative or tax policies; political and social tensions; hostilities or political problems in other countries that 
could impact international trade, the price of commodities and the global economy. 
 
Volatility in the securities markets in emerging market countries, let alone stand-alone markets such as 
Argentina, as well as possible further increases in interest rates in the United States and other developed or emerging 
markets, may have a negative impact on the trading value of our securities and the conditions under which we can 
access international capital markets. Additionally, in stand-alone markets there is a risk of governmental restrictions 
that may limit investment, and a higher risk associated with political developments. 
In addition, the SEC, the U.S. Department of Justice and other authorities often have substantial difficulties 
in bringing and enforcing actions against non-U.S. companies and non-U.S. persons, including company directors and 
officers, in certain stand-alone and emerging markets, including Argentina and Mexico.  
Any of these factors, as well as volatility in the capital markets, may adversely affect our business, results of 
operations, financial condition, the value of our series A shares and ADSs, and our ability to meet our financial 
obligations.  
We could be subject to direct and indirect restrictions on exports under Argentine law. 
Although the Argentine Hydrocarbons Law generally grants the right to export hydrocarbons, subject to non-
objection by the SdE, and ensures that once export requirements are met, the right to export cannot be revoked (see 
“Item 4—Information on the Company—Industry and Regulatory Overview—Oil and Gas Regulatory Framework in 
Argentina—Ley de Bases”), the specific objection process is expected to be further defined through an SdE resolution. 
Additionally, hydrocarbons exports are allowed only if the volumes are not needed for the domestic market and are 
sold at reasonable prices. In the past, oil and gas companies have experienced export restrictions, limiting their ability 
to benefit from higher international prices when they exceed domestic prices in Argentina. 
Even though the Ley de Bases approved changes to the Argentine Hydrocarbons Law to reduce restrictions 
on hydrocarbon exports (see “—Our business is largely dependent on economic and political conditions in 
Argentina”), an authorization from the Argentine government is still required to export hydrocarbons until above-
mentioned SdE resolution is enacted. In the case of not obtaining oil export permits, our operations could be affected, 
as well as our revenues and financial results. 
Until 2024, exports of crude oil and oil by-products in Argentina required prior registration in the Argentine 
Registry of Export Operations Agreements (Registro de Contratos de Operaciones de Exportación) and authorization 
by the SdE. The Ley de Bases modified the Argentine Hydrocarbons Law, establishing that producers of crude oil and 
oil by-products may freely export hydrocarbons and/or their derivatives, absent objection by the SdE. The effective 
exercise of this right is subject to the regulations issued by the Argentine Executive Branch, which, among other 
aspects, must consider: (i) the usual requirements related to the access of technically proven resources; and (ii) that 
the eventual objection of the SdE may only (a) be formulated within 30 days after the SdE acknowledges the export, 
and (b) must be based on technical or economic reasons related to the security of supply. Once said term has elapsed, 
the SdE may not raise any objection whatsoever.  
On November 28, 2024, the Argentine Executive Branch issued Decree No. 1057/2024 to regulate the Ley de 
Bases, detailing export procedures and the maintenance of the Argentine Registry of Export Operations Agreements. 
The decree introduces an objection procedure for hydrocarbon exports, allowing the SdE to object within 30 business 
days based on technical-economic studies if supply security is affected. Specific grounds for objection include 
insufficient hydrocarbons, failure to demonstrate projected availability, inaccurate information, and significant 
changes in domestic market prices. 
The principles of equality, reasonableness, proportionality, and non-discrimination must be observed, and the 
objection procedure is expected to be further detailed by an SdE resolution, replacing previous resolutions. We cannot 
predict when the SdE will issue such regulation and the nature of its content. See “Item 4—Information on the 
Company—Industry and Regulatory Overview—Oil and Gas Regulatory Framework in Argentina—Ley de Bases.” 
In addition, we cannot predict if restrictions on exports will be reintroduced, or whether future measures will 
be taken that adversely affect our ability to export and import gas, crude oil, or other products and, consequently, 

 
33 
 
affect our financial condition, results of operations, and cash flows. For additional information, please see “Item 10—
Additional Information—Exchange Controls.” 
With respect to natural gas, Argentine Law No. 24,076 (“Natural Gas Law”) and the related regulations 
require that all domestic market needs be considered when authorizing long-term exports of natural gas. In this sense, 
the SdE may authorize export operations of natural gas surplus provided they are subject to interruption upon local 
supply shortages. In recent years, Argentine authorities have adopted certain measures which resulted in restrictions 
on the exports of natural gas from Argentina. Because of these restrictions, oil and gas companies have been forced to 
sell part of their natural gas production in the local market that was originally intended for the export market and have 
been unable in certain cases to comply wholly or partially with their export commitments.  
Current Argentine exchange controls and the implementation of further exchange controls could 
adversely affect our results of operations.  
The Argentine government and the BCRA have implemented certain measures that control and restrict the 
ability of companies and individuals to access the foreign exchange market. Those measures include, among others: 
(i) restricting access to the Argentine foreign exchange market for the purchase or transfer of foreign currency abroad 
for any purpose, including the payment of dividends to interested non-residents; (ii) restricting the acquisition of any 
foreign currency to be held as cash in Argentina; (iii) requiring exporters to repatriate and convert all export proceeds 
from goods and services into Argentine Pesos through the foreign exchange market; (iv) limiting the transfer of 
securities into and from Argentina; (v) implementing taxes on certain transactions involving the acquisition of foreign 
currency; and (vi) restricting access (including, but not limited to, in connection with the term for making such 
payments) to the currency exchange market to pay for imports of goods and services. In the past, the BCRA 
established certain additional restrictions such establishing certain mandatory refinancing on U.S. Dollar-denominated 
debt.  
Even though President Milei announced exchange controls would be lifted by year-end 2025, a detailed plan 
and the timing of such event have not been disclosed, and there can be no assurance that the BCRA will lift exchange 
controls in the near future, make modifications to these regulations, or even reimpose past restrictions or impose 
mandatory refinancing plans related to our indebtedness payable in foreign currency, establish more severe 
restrictions on currency exchange, or maintain the current Argentine Foreign Exchange Regulations or create multiple 
exchange rates for different types of transactions, substantially modifying the applicable exchange rate at which we 
acquire currency to service our outstanding liabilities denominated in currencies other than the Argentine Peso, all of 
which could affect our ability to comply with our financial obligations when due, raise capital, refinance our debt at 
maturity, obtain financing, execute our capital expenditure plans, import goods and services, which are needed for the 
execution of projects in the upstream and midstream sectors of the oil and gas industry and/or undermine our ability 
to pay interest and principal payments on the Notes.  
Given the unpredictable nature of political and economic developments, there can be no assurance that more 
restrictive exchange controls and transfer restrictions than those currently in effect will not be imposed. In the event 
of a crisis or a period of political, economic and social instability in Argentina resulting in a material economic 
contraction, there is a risk that the current government may adopt radical changes to its economic, exchange and 
financial policies. Such measures may be implemented to preserve the balance of payments, protect the foreign 
exchange reserves of the BCRA, prevent capital flight, or address a significant depreciation of the Argentine Peso. 
These measures could include, among others, the mandatory conversion of U.S. Dollar-denominated obligations of 
Argentine resident legal entities into Argentine Pesos. The imposition of such restrictions, combined with external 
factors beyond the Company’s control, could materially impact the Company’s ability to make payments in foreign 
currency. 
The extension of current exchange controls, or the implementation of stricter capital controls, could have an 
adverse impact on the Argentine government’s public finances, which could in turn have a detrimental effect on the 
Argentine economy and consequently on our business, operating results, and financial condition, including our ability 
to service financial debt obligations. For additional information, please see “Item 10—Additional Information—
Exchange Controls.” 
In addition, we cannot assure you that the Mexican government may not impose exchange controls or other 
confiscatory measures in the future. 

 
34 
 
The imposition of export duties and other taxes have adversely affected the oil and gas industry in 
Argentina and could adversely affect our results in the future. 
In the past, the Argentine government has imposed duties on exports, including exports of oil and liquid 
petroleum gas products (e.g., among others, by means of the Solidarity Law and Decree No. 488/2020). Under the 
current regulation, export duties on crude hydrocarbons and/or natural gas are capped at 8%, when Brent crude oil 
price is above US$60/bbl. For Brent crude oil price below US$45/bbl the tax rate is 0%. Between US$45/bbl and 
US$60/bbl, the tax rate is linear between 0% and 8%. 
An increase in export duties and taxes may have a material adverse effect on Argentina’s oil and gas industry 
and our results of operations. We produce exportable goods and an increase in export taxes would result in a reduction 
in our realization prices, our margins and our net income. We cannot guarantee the impact of those or any other future 
taxes and measures that might be adopted by the Argentine government on demand and prices for hydrocarbon 
products and, consequently, our financial condition and result of operations. 
The impact of inflation in Argentina on our costs could have a material adverse effect on our results of 
operations.  
Historically, inflation has materially undermined the Argentine economy and the Argentine government’s 
ability to create conditions that foster growth. In recent years, Argentina has experienced high inflation rates. The 
consumer price index published by the INDEC (Índice de Precios al Consumidor) (“CPI”) variation for the period 
from January 1, 2024 to December 31, 2024 was 117.8%.  
In the past, loose monetary policy and persistent fiscal deficits have contributed to high levels of inflation. In 
response, prior Argentine governments have implemented various measures to monitor and control the prices of key 
goods and services. The current administration, under President Milei, has shifted the macroeconomic policy 
framework to prioritize the elimination of the fiscal deficit and a substantial reduction in monetary issuance. As a 
result, CPI growth has subsided, with a month-on-month increase of 2.2% in January 2025 and 2.4% in February 
2024, equivalent to an annualized rate of approximately 32.9%. Notwithstanding this progress, if the value of the 
Argentine Peso is not fully stabilized through consistent fiscal and monetary policies, inflationary pressures may 
reemerge. 
High inflation rates affect the competitiveness of Argentina’s goods and services in the international 
markets, negatively impact employment, consumption and the level of economic activity and undermines confidence 
in Argentina’s banking system, which could further limit the availability of and access to domestic and international 
credit by local companies and political stability. Inflation remains a challenge for Argentina given its persistent 
nature. Argentina’s structural inflationary imbalances remain critical, which may cause the current levels of inflation 
to continue and have an adverse effect on Argentina’s economy and financial condition. Inflation can also lead to an 
increase in Argentina’s debt. 
Inflation in Argentina has contributed to a material increase in our operating costs and new well costs over 
the past years, as part of the goods and services involved in such activities are denominated in Argentine Pesos, which 
leads to increases in unit costs measured in U.S. Dollars during periods when the Argentine Peso inflation rate is 
greater than the depreciation of the Argentine Peso against the U.S. Dollar.  
Inflation rates could escalate in the future, and there is uncertainty regarding the effects that the measures 
adopted, or that may be adopted in the future, by the Argentine government to control inflation may have. See “—
Government intervention may adversely affect the Argentine economy and, as a result, our business and results of 
operations in Argentina” below. Increased inflation could adversely affect the Argentine economy, our cost structure, 
financial condition, our business, and the market price of our series A shares and the ADSs.  
Significant fluctuations in the value of the Argentine Peso could adversely affect the Argentine economy 
and our business and results of operations in Argentina.  
The ability of the Argentine government to stabilize and maintain a stable foreign exchange market is 
uncertain. Fluctuations, or a continued depreciation, in the value of the Argentine Peso may adversely affect the 
Argentine economy, our financial condition and results of operations. While most of our revenues are denominated in 

 
35 
 
U.S. Dollars, E&P players could be limited by the ability of refiners to pass through crude oil prices to the pump 
prices, which are denominated in local currency, in the event of significant increases in the Argentine Peso to U.S. 
Dollar exchange rate. A material depreciation of the Argentine Peso against the U.S. Dollar could negatively affect 
our average realized oil prices and financial performance, including our ability to service financial debt obligations, as 
well as the value of our ADSs. 
Furthermore, an appreciation of the Argentine Peso in real terms affects the competitiveness of the economy, 
including the oil and gas sector, as it makes goods and services denominated in local currency more expensive in 
relative terms. This could increase our operating and capital expenditures, and negatively affect our financial 
performance. A significant appreciation in real terms of the Argentine Peso against the U.S. Dollar also presents risks 
for the Argentine economy, including the possibility of a reduction in exports (as a consequence of the loss of 
external competitiveness). Such appreciation could also have a negative effect on the growth of the economy and 
employment and reduce tax collection in real terms. 
Our properties may be subject to expropriation by the Mexican and Argentine governments for public 
interest reasons.  
Our assets, which are mainly located in Argentina and, to a lesser extent, in Mexico, may be subject to 
expropriation by the Argentine and Mexican governments (or the government of any political subdivision thereof), 
respectively. We are engaged in the business of oil extraction and, as such, our business or our assets may be 
considered by the Argentine or Mexican governments, or the governments of other countries where we might invest 
in the future, to be a public service or essential for the provision of a public service. Therefore, our business is subject 
to political uncertainties, including expropriation or nationalization of our business or assets, loss of concessions, 
renegotiation or annulment of existing contracts, and other similar risks.  
In such an event, we may be entitled to receive compensation for the transfer of our assets under applicable 
law. However, the price received may not be sufficient, and we may need to take legal actions to claim appropriate 
compensation. Our business, financial condition and results of our operations could be adversely affected by the 
occurrence of any of these events.  
We cannot assure that any acts of expropriation by the Argentine or Mexican governments, changes in 
applicable laws and regulations, or adverse judicial or administrative interpretations of such laws and regulations will 
not have a material adverse effect on our operation and business, or the Argentine or Mexican economies in general 
and, as a result, adversely affect our financial condition, our results of operations.  
Government intervention may adversely affect the Argentine economy and, as a result, our business and 
results of operations in Argentina.  
In the past, the Argentine government has intervened directly in the economy through expropriation, 
nationalization, price controls and exchange controls, among others.  
Historically, the Argentine government has adopted measures to directly or indirectly control the access of 
private companies and individuals to foreign trade and foreign exchange markets, such as restricting its free access 
and imposing the obligation to repatriate and sell in the foreign exchange market all foreign currency revenues 
obtained from exports. These regulations prevent and limit us from offsetting the risk derived from our exposure to 
the U.S. Dollar. Our business and operations in Argentina may also be adversely affected by measures adopted by the 
Argentine government to address inflation and promote sustainable macroeconomic growth.  
A low economic growth rate and high inflation scenario could occur in the future as a result of the 
accumulation of macroeconomic imbalances in recent years, the Argentine government’s regulatory actions and 
difficult international economic conditions. We cannot give any assurance that the policies implemented by the 
Argentine government will not adversely affect our business, results of operations, financial condition, value of our 
securities and ability to meet our financial obligations.  
Argentina’s economy is highly sensitive to local political developments, which in the past have had an 
adverse impact on the level of investment. Future developments may adversely affect Argentine economy and, in 

 
36 
 
turn, our business, results of operations, financial condition, the value of our securities, and our ability to meet our 
financial obligations.  
In the future, the Argentine government may impose further exchange controls and restrictions on transfers 
abroad, restrictions on the movement of capital or take other measures in response to capital flight or a significant 
depreciation of the Argentine Peso, which could limit our ability to access the international capital markets. Such 
measures could lead to political and social tensions and undermine the Argentine government’s public finances, as 
has occurred in the past, which could have an adverse effect on economic activity in Argentina and, consequently, 
adversely affect our business and results of operations and cause the market value of our series A shares or ADSs to 
decline.  
Oil and gas exploitation concessions, exploration permits and production and exploration contracts in 
Argentina and Mexico are subject to certain conditions and may be revoked or not renewed.  
Argentina  
The Argentine Hydrocarbons Law is the main regulatory framework of the hydrocarbons industry, as it 
created a system of exploration permits and production concessions awarded by the state (federal or provincial, 
depending on the location of the resources), through which companies hold exclusive rights to explore, develop, 
exploit and take title of the production at the wellhead, in exchange for a royalty payment and adherence to the 
general taxation regime.  
The Argentine Hydrocarbons Law, as amended, establishes that oil and gas exploitation concessions will 
have the following durations: (i) 25 years for conventional exploitation concessions, (ii) 35 years for unconventional 
exploitation concessions, and (iii) 30 years for offshore concessions, in each case, from the date of the resolution 
granting them.  
Pursuant to the modifications introduced by Article 115 of the Ley de Bases, in new concessions, the federal 
or provincial executive branch, as appropriate, at the time of defining the terms and conditions, may determine other 
terms of up to a maximum of 10 additional years to those mentioned above, provided that such decision by the the 
federal or provincial executive branch, as appropriate, its well-founded and motivated. In no case may the terms be set 
in perpetuity. Concessions granted prior to the enactment of the Ley de Bases will continue to be governed by the 
terms established by the legal framework existing at the date of their approval. 
No assurance can be given that our concessions will be renewed in the future by the competent authorities 
based on the investment plans submitted to that effect, or that such authorities will not impose additional requirements 
for the renewal of such concessions or permits. Additionally, five of our concessions are unconventional concessions 
and therefore were granted for a 35-year period and with royalties of 12%, under the terms prescribed by Law No. 
27,007. We cannot assure you that any future legislation the Argentine government may enact from time to time may 
not affect such concessions.  
Exploration permits and exploitation concessions provide a vested right that cannot be terminated without 
legal indemnification. Nonetheless, relevant provincial enforcement authorities are entitled to revoke these licenses in 
the event of a breach of the permit or concession conditions by the licensee (Section 80 of Law No. 17,319). 
Licensees can also partially or totally relinquish, at any time, the acreage of a permit or concession. If an exploration 
permit is relinquished, the licensee will be bound to pay any investment amounts committed and not fulfilled 
(Sections 20 and 81 of the Argentine Hydrocarbons Law). 
The Ley de Bases introduced amendments to the Argentine Hydrocarbons Law, with respect to oil and gas 
concessions. Among the main points modified by the Ley de Bases, it is provided that the request for subdivision of 
the area for the conversion of conventional to unconventional concession will only be available until December 31, 
2028, and its term will only be 35 years, without extensions. 
It is not possible to ensure what effects these amendments to the Argentine Hydrocarbons Law will have on 
the concessions granted to companies in Argentina (including our concessions) nor when we will be able to see the 
effects of these modifications. Therefore, we cannot predict what effects the Ley de Bases will have on our 

 
37 
 
concessions, and consequently, on our operational performance and, therefore, our financial condition, operating 
results, and cash flows. 
In addition, no assurance can be given that our exploitation concessions will be renewed in the future by the 
relevant provincial authorities based on the investment’s plans submitted to that effect, or that such authority will not 
impose additional requirements for the renewal of such concessions. Moreover, under the current regulatory 
framework, the granting authority retains the possibility of revoking concessions if certain conditions are met. 
Mexico 
Our E&P license contract is valid for 30 years and may be renewed for up to two additional periods of up to 
five years each, subject to the terms and conditions set out in the contract. The power and authority to extend the term 
of existing and future contracts lies with the SENER. Under the existing contracts, for an E&P license contract to be 
eligible for an extension, the developer must (i) be in compliance with the terms of such contracts, (ii) submit an 
amendment proposal to the development plan and (iii) commit to maintain ‘sustained regular production’ throughout 
each extension. 
No assurance can be given that our contracts will be renewed in the future by the SENER (or any substitute 
authority thereto) based on the investment plans submitted to that effect, that such authority will not impose 
additional requirements for the renewal of such contract, or that we will continue to have a good business relationship 
with the new and future administrations.  
For additional context on the regulatory changes in Mexico concerning the CNH, see “Item 4—Information 
on the Company—Industry and Regulatory Overview—Mexico’s Oil and Gas Industry Overview—Oil and Gas 
Regulatory Framework in Mexico.” 
A global or regional financial crisis and unfavorable credit and market conditions may negatively affect 
our liquidity, customers, business, and results of operations.  
The effects of a global or regional financial crisis and related turmoil in the global financial system may have 
a negative impact on our business, financial condition and results of operations.  
The effects of a global economic crisis on our customers and on us cannot be predicted. Weak global and 
local economic conditions could lead to reduced demand or lower prices for energy, hydrocarbons and related oil 
products and petrochemicals, which could have a negative effect on our revenues. Economic factors such as 
unemployment, inflation and the unavailability of credit could also have a material adverse effect on the demand for 
energy and, therefore, on our business financial condition and results of operations. The financial and economic 
situation in Argentina, Mexico or in other countries in Latin America, may also have a negative impact on us and 
third parties with whom we do, or may do, business. See “—The Argentine economy can be adversely affected by 
economic developments in the global financial markets, and by more general contagion effects from other financial 
markets, which could have a material adverse effect on Argentina’s economic growth.”  
The Argentine economy can be adversely affected by economic developments in the global financial 
markets, and by more general contagion effects from other financial markets, which could have a material adverse 
effect on Argentina’s economic growth.  
Financial and securities markets in Argentina and the Argentine economy are influenced by the effects of 
global or regional financial crises and market conditions in other markets worldwide. Global economic instability 
such as uncertainty about global trade policies, sharp drops or increases in commodities prices, the deterioration of 
economic conditions in Brazil (Argentina’s main trading partner) and of the economies of other major trading partners 
of Argentina, such as China or the United States, the withdrawal of the United Kingdom from the European Union 
(Brexit), geopolitical tensions between the United States and a number of foreign countries, the ongoing conflict 
between Russia and Ukraine, and more recently between Israel, Iran and Hamas, and China and Taiwan, decisions by 
the OPEC and other non-OPEC oil-producing nations with respect to oil production quotas, idiosyncratic, political 
and social discords, terrorist attacks, sovereign debt downgrades, a pandemic disease, could impact the Argentine 
economy and jeopardize Argentina’s ability to correct its existing macro imbalances, among others. Although 
economic conditions vary from country to country, investors’ reactions to events occurring in one country sometimes 

 
38 
 
demonstrate a contagion effect in which an entire region or class of investment is disfavored by international 
investors. 
Consequently, there can be no assurance that the Argentine economy and securities markets will not be 
adversely impacted by events affecting the world, a particular region, developed economies, emerging markets or any 
of Argentina’s major trading partners, which could in turn adversely affect our business, financial condition and 
results of operations, and the market value of our ADSs. Furthermore, a significant devaluation of the currencies of 
our trading partners or trade competitors may adversely affect the competitiveness of Argentina and, consequently, 
adversely affect Argentina’s economy and our financial condition and results of operations, including our ability to 
service financial debt obligations.  
Failure to adequately address actual and perceived risks of institutional deterioration and corruption may 
adversely affect Argentina’s economy and financial condition and, consequently, our business.  
A lack of a solid and transparent institutional framework for contracts with the Argentine government and its 
agencies and corruption allegations have affected and continue to affect Argentina. In Transparency International’s 
2023 Corruption Perceptions Index survey of 180 countries, Argentina was ranked 98th (with one being the least 
corrupt country and 180 being the most corrupt country), a deterioration compared to the previous survey in 2022.  
As of the date of this annual report, there are various ongoing investigations into allegations of money 
laundering and corruption being conducted by the Argentine Public Prosecutor (Ministerio Público Argentino). 
Companies involved in the investigations may be subject to, among other consequences, a decrease in their credit 
ratings, claims filed by their investors, and may further experience restrictions in their access to financing through the 
capital markets, together with a decrease in their income. The potential outcome of these and other ongoing 
corruption-related investigations is uncertain, but they have already had an adverse impact on the image and 
reputation of those companies that have been implicated, as well as on the general market perception of the economy, 
political environment and the capital markets in Argentina. We have no control over and cannot predict the outcome 
of any such investigations or allegations nor their effect on the Argentine political and economic instability, nor the 
can we predict the adverse effect on our commercial activities and results of operations.  
Recognizing that failing to address these issues could increase the risk of political instability, distort 
decision-making processes, and negatively affect Argentina’s international reputation and its ability to attract foreign 
investment, the Argentine government has announced several measures aimed at strengthening Argentine institutions 
and reducing corruption. These measures include reducing criminal sentences in exchange for cooperation with the 
government in corruption investigations, greater access to public information, the restitution to the state of assets from 
corrupt officials, increasing the powers of the Anti-Corruption Office, presenting a draft of a new public ethics law, 
among others. The Argentine government’s ability to implement these initiatives is uncertain, as it would be subject 
to independent judicial review, as well as legislative support from opposition parties. 
Recognizing that the failure to address these issues could increase the risk of political instability, distort 
decision-making processes and adversely affect Argentina’s international reputation and ability to attract foreign 
investment. In turn, this could impact our ability to attract new investors to our Company, which could affect our 
financial condition and the market value of our ADSs.    
The Argentine government owns the hydrocarbons reserves located in the subsoil in Argentina. 
The Argentine Hydrocarbons Law provides that liquid and gaseous hydrocarbon deposits located in the 
territory of the Argentina and in its continental shelf belong to the Argentine government, either at the federal or 
provincial level, depending on the location of such deposits. See “Item 4—Information on the Company—Property, 
Plant and Equipment.” However, the E&P of oil and natural gas are conducted through exploration permits and 
exploitation concessions granted by the federal or provincial government, as applicable, to public and private 
companies. Access to crude oil and natural gas reserves is essential to an oil and gas company’s sustained production 
and generation of income, and our ability to generate income would be materially and adversely affected if the 
Argentine government were to restrict or prevent us from exploring or extracting any of the crude oil and natural gas 
reserves that it has assigned to us or if we are unable to compete effectively with other oil and gas companies in future 
bidding rounds for additional E&P rights in Argentina. See “Item 4—Information on the Company—Industry and 
Regulatory Overview—Oil and Gas Regulatory Framework in Argentina.”

Economic conditions and government policies in Mexico and elsewhere may have a material impact on 
our operations. 
A deterioration in Mexico’s economic condition, social instability, political unrest, changes in governmental 
policies, or other adverse social developments in Mexico could adversely affect our business and financial condition. 
Those events, including changes in energy policy and regulation, could also lead to increased volatility in the foreign 
exchange and financial markets, thereby affecting our ability to obtain financing. Additionally, the Mexican 
government has announced several budget cuts in the past in response to declines in international crude oil prices. 
Any new budget cuts could adversely affect the Mexican economy and, consequently, our business, financial 
condition, operating results and prospects.  
In the past, Mexico has experienced several periods of slow or negative economic growth, high inflation, 
high interest rates, currency devaluation and other economic problems. These problems may worsen or reemerge, as 
applicable, in the future and could adversely affect our business. A worsening of international financial or economic 
conditions, such as a slowdown in growth or even a recession in Mexico’s trading partners, including the United 
States, or the emergence of a new financial crisis, could have adverse effects on the Mexican economy, our financial 
condition and our ability to service our debt.  
Also, the Mexican government has had significant influence in the Mexican economy in the past and will 
likely continue to do so. Changes in the legal framework and policies may adversely affect our business and the value 
of our securities.  
Criminal activity in Mexico could affect our operations.  
In recent years, Mexico has experienced a period of increasing criminal activity, primarily due to the 
activities of drug cartels and related criminal organizations. In addition, the development of the illicit market in fuels 
in Mexico has led to increases in theft and illegal trade in the fuels that we produce. In response, the Mexican 
government has implemented various security measures and has strengthened its military and police forces. Despite 
these efforts, criminal activity continues to exist in Mexico, and could worsen in 2024, if criminal groups seek to take 
advantage of the upcoming elections to expand their control over the local governments and markets. These activities, 
their possible escalation and the violence associated with them, in an extreme case, may have a negative impact on 
our financial condition and results of operations.  
Economic and political developments in Mexico may adversely affect Mexican economic policy and, in 
turn, our operations. 
As of the date of this annual report, Movimiento de Regenaracion Nacional (Morena), the political party of 
Mexican President Claudia Sheinbaum, holds a majority of seats in the Mexican House of Representatives (Cámara 
de Diputados) and holds the largest number of seats in the Mexican Senate (Senado de la República) relative to any 
other party. In recent years, the Mexican Executive Branch and Congress have applied significant pressure on the 
Judicial Branch, particularly on Mexico’s Supreme Court of Justice. This concentration of power, along with any 
political or economic changes resulting from these developments, could have a negative impact on our business, 
financial position, or operating results. 
On September 15, 2024, a constitutional reform was enacted in Mexico, introducing significant changes to 
the judicial system, including the popular election of judges, magistrates, and Supreme Court justices. The Mexican 
Judicial Reform (as defined below) has led to nationwide judicial strikes, disrupting judicial proceedings and 
potentially causing delays in litigation and contract enforcement. These developments create regulatory uncertainty 
that may impact our business operations and legal protections in Mexico. For additional context on the regulatory 
changes in Mexico, see “Item 4—Information on the Company—Industry and Regulatory Overview—Mexico’s Oil 
and Gas Industry Overview—Oil and Gas Regulatory Framework in Mexico.” 
Economic conditions in Mexico are closely linked to the economic conditions in the United States due to the 
countries’ geographic proximity and the high degree of economic activity between the two countries generally, 
including the trade facilitated by the North American Free Trade Agreement (NAFTA). As a result, political and 
economic developments in the United States, including but not limited to the recent developments regarding tariffs 

 
40 
 
imposed by the United States on imports from Mexico, can also have an impact on the exchange rate between the 
U.S. Dollar and the Mexican Peso, economic conditions in Mexico and the global capital markets. 
The administration of U.S. President Donald Trump has introduced significant changes in trade policies, 
including the imposition of new tariffs on imports from Canada, Mexico, and China, with additional measures under 
consideration. For more information on changes in U.S. trade and oder policies, and their impact, see “Risks Related 
to Our Business and Industry—Changes in U.S. trade and other policies under the Trump administration may 
adversely impact our business, financial condition, and results of operations.” These tariffs, along with potential 
retaliatory actions by these and other countries, could disrupt global trade flows, and increase operational costs for 
companies reliant on international supply chains. 
Additionally, on January 20, 2025, President Trump issued an executive order directing the U.S. Secretary of 
State to recommend the designation of certain international cartels and transnational criminal organizations as FTOs 
and SDGTs. The U.S. Department of Justice subsequently issued memoranda prioritizing enforcement actions against 
cartels and transnational criminal organizations, including those operating in Mexico. These designations may impose 
additional compliance and operational challenges for companies, like ours, with activities in Mexico. 
Other events and changes, and any political and economic instability in Mexico, could have a material 
adverse effect on the country’s economy. The extent of such an impact cannot be accurately predicted. We cannot 
provide any assurances that political developments in Mexico will not adversely affect the Mexican economy or the 
oil and gas industry and, in turn, our business. 
The Mexican nation owns the hydrocarbons reserves located in the subsoil in Mexico. 
The Mexican Constitution provides that the Mexican nation, and not us, owns all petroleum and other 
hydrocarbon reserves located in the subsoil in Mexico. Article 27 of the Mexican Constitution provides that the 
Mexican government will carry out E&P activities through contracts with third parties or allocations awarded to State 
Public Enterprises (empresas públicas del Estado). The Mexican Hydrocarbons Law, under which the license 
agreement for the block CS-01 was executed and is governed, allowed us and other oil and gas companies to explore 
and extract the petroleum and other hydrocarbons reserves located in Mexico, subject to the entry into agreements 
pursuant to a competitive bidding process. After the repeal of the Mexican Hydrocarbons Law, the Mexican 
Hydrocarbons Sector Law stipulates that the SENER may exceptionally enter into agreements for the exploration and 
extraction of petroleum and other hydrocarbons, subject to a competitive bidding process. Access to crude oil and 
natural gas reserves is essential to an oil and gas company’s sustained production and generation of income, and our 
ability to generate income would be materially and adversely affected if the Mexican government were to restrict or 
prevent us from exploring or extracting any of the crude oil and natural gas reserves that it has assigned to us or if we 
are unable to compete effectively with other oil and gas companies in future bidding rounds for additional E&P rights 
in Mexico. 
For additional context on the regulatory changes in Mexico, see “Item 4—Information on the Company—
Industry and Regulatory Overview—Mexico’s Oil and Gas Industry Overview—Oil and Gas Regulatory Framework 
in Mexico.” 
Health crises such as the COVID-19 pandemic could have a significant adverse effect on our business 
operations.  
The COVID-19 pandemic had a significant adverse impact on the global economy and our Company. The 
COVID-19 pandemic resulted in the imposition of local, municipal and national governmental “shelter-in-place” and 
other quarantine measures, border closures and other travel restrictions, closure of non-essential businesses, 
suspension of visas, nation-wide lockdowns, closing of public and private institutions, extension of holidays, among 
many others, causing unprecedented commercial disruption in a number of jurisdictions, including Mexico and 
Argentina.  
During 2020, the Company’s revenues and financial condition were severely hit due to the reduced demand 
for oil and gas, and the collapse in oil and gas prices, driven by the COVID-19 pandemic. Due to these issues, we 
decided to stop all drilling and completion activities, both in Argentina and Mexico, which negatively impacted our 
production by delaying development projects.  

 
41 
 
Although the negative effects of the COVID-19 pandemic on us and the global economy have subsided, we 
cannot predict or estimate the ultimate negative impact that a resurgence of COVID-19 or another pandemic would 
have on our results of operations and financial condition, since it will depend on future developments outside of our 
control, including the intensity and duration of the pandemic, as well as measures taken to contain the pandemic or 
mitigate its economic impact by the Argentine or Mexican governments. 
We are subject to risks related to a certain joint and several tax liability provision in Mexico, by means of 
which Vista could be held as jointly and severally liable in connection with any income tax amounts arising from 
the transfer of its shares between foreign residents without a permanent establishment in Mexico, if such 
transactions are not reported to the Mexican tax authorities.  
The Mexican government approved and published a tax provision in the Mexican Federal Official Gazette 
whereby from January 1, 2022, Mexican resident companies may be joint and severally liable for the taxes triggered 
by non-Mexican tax residents on the sale or disposition, to another non-Mexican tax resident party, of their shares or 
securities representing property of assets, issued by such companies, if the relevant Mexican resident company fails to 
provide certain information in respect of certain dispositions or sales to the Mexican tax authorities and the non-
Mexican seller fails to comply with the obligation to pay the relevant tax. Given the mechanisms and procedures 
inherent to stock exchanges, including the volume of trading in the NYSE, Mexican companies, including us, have 
practical challenges in identifying and tracking the sale or disposition of the ADSs held by our investors, irrespective 
of them being Mexican or non-Mexican tax resident. Therefore, if the non-Mexican resident fails to pay taxes 
triggered on the sale and we fail to comply with the abovementioned information obligation, the tax authorities may 
assess joint and several liability on the Company for any unpaid taxes derived from the disposition or sale of the 
ADSs conducted by non-Mexican residents to another non-Mexican resident where certain requirements set forth in 
the Mexican Tax Law and its regulations are not complied with for such sale or disposition of ADSs to be exempt in 
Mexico. This potential assessment could have an adverse effect on our business, equivalent to the joint and several 
liability of the unpaid taxes. 
However, Vista has appealed the tax provision through an amparo proceeding, seeking an exemption from 
the obligation to provide the relevant information and, as a result, to avoid being subject to joint and several tax 
liability. Vista obtained a favorable final decision from a Collegiate Court (Tribunal Colegiado) pursuant to binding 
precedent from the Second Chamber of the Mexican Supreme Court of Justice established in docket A.R. 528/2022. 
As a result, Vista is now only required to submit the notice concerning the share ownership of the parties referred to 
in Section 49 Bis 2 of the Circular Única de Emisoras and is not obligated to report share transfers carried out 
between non-residents. 
Risks Related to our series A shares and the ADSs 
The series A shares and ADSs are traded in more than one market, and this may result in price 
variations; in addition, investors may not be able to easily move securities for trading between such markets.  
As of the date of this annual report, our series A shares are listed and traded on the Mexican Stock Exchange 
and ADSs are listed on the NYSE. Markets for our series A shares or for the ADSs may not have liquidity and the 
price at which the series A shares or the ADSs may be sold is uncertain.  
Trading in the ADSs or our series A shares on these markets takes place in different currencies (U.S. Dollars 
on the NYSE and Mexican Pesos on the Mexican Stock Exchange), and at different times (resulting from different 
time zones, different trading days and different public holidays in the United States and Mexico). The trading prices 
of the securities on these two markets may differ due to these and other factors. Any decrease in the price of our series 
A shares on the Mexican Stock Exchange could cause a decrease in the trading price of the ADSs on the NYSE. 
Investors could seek to sell or buy our shares to take advantage of any price differences between the markets through 
a practice referred to as arbitrage. Any arbitrage activity could create unexpected volatility in both our share prices on 
one exchange, and the ADSs available for trading on the other exchange. In addition, holders of ADSs will not be 
immediately able to surrender their ADSs and withdraw the underlying series A shares for trading on the other market 
without effecting necessary procedures with the Depositary. This could result in time delays and additional cost for 
holders of the ADSs.  

 
42 
 
The trading prices for the series A shares and the ADSs may fluctuate significantly.  
Volatility in the market price of our series A shares and the ADSs may prevent investors from selling their 
securities at or above the price that they paid for them. The market price and market liquidity of our series A shares 
and the ADSs may be adversely affected by several factors, including, but not limited to, the extent of investor 
interest in us, the attractiveness of our series A shares and the ADSs in comparison to other equity securities (for 
instance, shares issued by a company with larger operating history in our own industry), our financial performance 
and general market conditions. Certain additional factors that could negatively affect, or result in fluctuations in, the 
price of our series A shares and the ADSs include actual or anticipated variations in our operating results; potential 
differences between our actual financial and operating results and those expected by investors; investors’ perceptions 
of our prospects and the prospects of our sector; new laws or regulations or new interpretations of laws and 
regulations, including tax guidelines, applicable to the energy sector, our series A shares and/or the ADSs; general 
economic trends and risks in the United States, Latin American or global economies or financial markets, including 
those resulting from pandemics, war, incidents of terrorism or responses to such events; changes in our operations or 
earnings estimates or publication of research reports about us or the Latin American energy industry; market 
conditions affecting the Latin American economy generally or borrowers in Latin America specifically; significant 
volatility in the market price and trading volume of securities of companies in the energy sector, which are not 
necessarily related to the operating performance of these companies; additions to or departures from our Executive 
Team; completing (or failing to complete) additional acquisitions or executing additional concession agreements; 
speculation in the press or investment community; changes in the credit ratings or outlook assigned to Latin American 
countries, particularly Mexico and Argentina, and entities of the energy sector; political conditions or events in 
Argentina, Mexico, the United States and other countries; and enactment of legislation or other regulatory 
developments that adversely affect us or our industry.  
The stock markets in general have experienced extreme price and volume fluctuations that have often been 
unrelated or disproportionate to the operating performance of the companies involved. We cannot assure you that 
trading prices and valuations will be sustained. These broad market and industry factors may materially adversely 
affect the market price of our series A shares and the ADSs, regardless of our operating performance. Market 
fluctuations, as well as general political and economic conditions in the markets in which we operate, such as 
recession or currency exchange rate fluctuations, may also adversely affect the market price of our series A shares and 
ADSs. Following periods of volatility in the market price of a company’s securities, that company may often be 
subject to securities class-action litigation. This kind of litigation may result in substantial costs and a diversion of 
management’s attention and resources, which would have a material adverse effect on our business, results of 
operations and financial condition.  
The relatively low liquidity and high volatility of the Mexican securities market may cause trading prices 
and volumes of our series A shares and the ADSs to fluctuate significantly.  
The Mexican Stock Exchange is one of Latin America’s largest exchanges in terms of aggregate market 
capitalization of the companies listed therein, but it remains relatively illiquid and volatile compared to other major 
foreign stock markets. Although the public participates in the trading of securities on the Mexican Stock Exchange, a 
substantial portion of trading activity on the Mexican Stock Exchange is conducted by or on behalf of large 
institutional investors. The trading volume for securities issued by emerging market companies, such as Mexican 
companies, tends to be lower than the trading volume of securities issued by companies in more developed countries. 
These market characteristics may limit the ability of a holder of our series A shares and may also adversely affect the 
market price of the series A shares and, as a result, the market price of the ADSs.  
If securities or industry analysts do not publish research reports about our business, or publish negative 
reports about our business, the price and trading volume of our series A shares and the ADS could decline.  
The trading market for our series A shares and the ADSs may be impacted in part on the research and reports 
that securities or industry analysts publish about us, our business, our market or our competitors. If no securities or 
industry analysts covers us, the trading price for our series A shares and the ADSs may be negatively impacted. If one 
or more of the analysts who covers us downgrades us or releases negative publicity about our series A shares and 
ADSs, our share price would likely decline. If one or more of these analysts ceases to cover us or fails to regularly 
publish reports on us, interest in our series A shares and the ADSs may decrease, which may cause our share price or 
trading volume to decline.

As a foreign private issuer, we have different disclosure and other requirements than U.S. domestic 
registrants.  
As a foreign private issuer, we are subject to different disclosure and other requirements than domestic U.S. 
registrants. For example, as a foreign private issuer, in the United States, we are not subject to the same disclosure 
requirements as a domestic U.S. registrant under the Exchange Act, including the requirements to prepare and issue 
quarterly reports on Form 10-Q or to file current reports on Form 8-K upon the occurrence of specified significant 
events, the proxy rules applicable to domestic U.S. registrants under Section 14 of the Exchange Act or the insider 
reporting and short-swing profit rules applicable to domestic U.S. registrants under Section 16 of the Exchange Act. 
In addition, we have relied, and intend to keep relying, on exemptions from certain U.S. rules which permit us to 
follow Mexican legal requirements rather than certain of the requirements that are applicable to U.S. domestic 
registrants.  
Furthermore, foreign private issuers are required to file their annual report on Form 20-F within 120 days 
after the end of each fiscal year, while U.S. domestic issuers that are accelerated filers are required to file their annual 
report on Form 10-K within 75 days after the end of each fiscal year. Foreign private issuers are also exempt from 
Regulation Fair Disclosure under the Securities Act, aimed at preventing issuers from making selective disclosures of 
material information. As a result of the above, even though we are required to file reports on Form 6-K disclosing the 
information which we have made or are required to make public pursuant to Mexican law, or are required to distribute 
to shareholders generally, and that is material to us, you may not receive information of the same type or amount that 
is required to be disclosed to shareholders of a U.S. company.  
We cannot predict if investors will find our series A shares or the ADSs less attractive because we rely on 
these exemptions. If some investors find our series A shares and the ADSs less attractive as a result, there may be a 
less active trading market for our series A shares and the ADSs and our share price may be more volatile.  
ADS holders may be subject to additional risks related to holding ADSs rather than series A shares.  
Because ADS holders do not hold their series A shares directly, they are subject to additional risks, including 
as an ADS holder, you may not be able to exercise shareholder rights; distributions on the series A shares represented 
by your ADSs are paid in Mexican Pesos to a custodian through S.D. Indeval, Institución para el Depósito de Valores, 
S.A. de C.V. (“Indeval”) and before such custodian transfers any such distributions to the depositary for your benefit, 
it would be required to deduct withholding taxes, if any. The depositary would also be required to convert 
distributions made in Mexican Pesos into U.S. Dollars. Additionally, if the exchange rate fluctuates significantly prior 
to the depositary converting any distribution into U.S. Dollars, the amount of such distribution may decrease in terms 
of U.S. Dollars; and we and the depositary may amend or terminate the Deposit Agreement without the ADS holders’ 
consent in a manner that could prejudice ADS holders or that could affect the ability of ADS holders to transfer 
ADSs.  
We have granted, and may continue to grant, share incentive awards, which may result in increased 
share-based compensation expenses and holders of our series A shares and ADSs may suffer further dilution.  
In April 2018, we adopted our Long-Term Incentive Plan (“Plan”) with the purpose of attracting and 
retaining talented individuals as officers, directors, employees, and consultants who are critical to our success, 
incentivizing their performance, and aligning their interests with ours. Under the Plan, our Board of Directors is 
authorized to grant restricted series A shares or ADSs (“Restricted Stock”) and options to purchase our series A shares 
or ADSs (“Stock Options”) to our officers, directors, employees, and consultants. We reserved 8,750,000 series A 
shares, issued on December 18, 2017, for the implementation of the Plan. Additionally, the series A shares 
repurchased by the Company through our buy-back program may be allocated to the Plan. 
 
The vesting of series A shares reserved for the Plan (or the allocation of series A shares repurchased by the 
Company through our buy-back program) could result in immediate dilution to our existing shareholders and may 
also have a dilutive effect on our earnings per share. If all series A shares currently reserved for the Plan, in addition 
to all shares repurchased through the ongoing buy-back program, were to become outstanding, our issued and 
outstanding share capital would increase by 3.7%, from 95,285,451 series A shares outstanding as of December 31, 
2024, to 98,781,026 series A shares. See “Item 6—Directors, Senior Management and Employees—Long-Term 
Incentive Plan.” 

 
44 
 
 
ADS holders may be unable to exercise voting rights with respect to the shares underlying the ADSs at 
our shareholders’ meetings.  
The depositary is treated by us for all purposes as the shareholder with respect to the shares underlying your 
ADSs. As a holder of ADSs, you do not have direct shareholder rights and may exercise voting rights with respect to 
the shares represented by the ADSs only in accordance with the Deposit Agreement relating to the ADSs. There are 
no provisions under Mexican law or under our bylaws that limit the exercise by ADS holders of their voting rights 
through the depositary with respect to the underlying series A shares. However, there are practical limitations on the 
ability of ADS holders to exercise their voting rights due to the additional procedural steps involved in 
communicating with these holders. ADS holders may be unable to exercise voting rights with respect to the series A 
shares underlying the ADSs as a result of these practical limitations.  
Preemptive rights may be unavailable to non-Mexican holders of ADSs and, as a result, such holders may 
suffer dilution.  
Under our current by-laws, whenever we issue new shares for subscription and for payment in cash, subject 
to certain exceptions, such as those related to public offerings, mergers, or conversion of convertible securities or 
when the shareholders’ meeting or board of directors (in the latter case when such authority is delegated to the board 
of directors by the shareholders’ meeting for a particular issuance) decide otherwise, we must grant preemptive 
subscription rights to our shareholders, giving them the right to purchase a sufficient number of shares to maintain 
their existing ownership percentage. We may not be able to offer preemptive rights to foreign shareholders and ADS 
holders identical to those of our shareholders residing in Mexico in connection with any future issuance of shares 
unless we comply with certain specific requirements under the laws and regulations of the applicable jurisdictions of 
our non-Mexican shareholders. In the case of United States shareholders and ADS holders, we might not be able to 
offer them shares pursuant to preemptive rights granted to our shareholders in connection with any future issuance of 
shares, unless the offer of such shares is registered under the Securities Act or an exemption from the registration 
requirement is available.  
We intend to evaluate, at the time of any preemptive prescription rights offering, the costs and potential 
liabilities associated with a registration statement or similar requirement to enable U.S. or other non-
Mexican shareholders and ADS holders to exercise their preemptive subscription rights in the event of an issuance of 
shares; the indirect benefits of enabling U.S. and other non-Mexican shareholders and ADS holders to exercise 
preemptive subscription rights; and any other factors that we consider appropriate at the time. We will then decide 
whether to file such a registration statement or otherwise comply with a similar requirement.  
In the event that a required registration statement or similar requirement is not filed or satisfied, U.S. or other 
non-Mexican shareholders or ADS holders, would not be able to exercise their preemptive subscription rights in 
connection with future issuances of our shares, and their stake in the Company might be diluted. In this event, the 
proportion of the economic and voting interests of such U.S. or other non-Mexican shareholders or ADS holders in 
our total equity could decrease in proportion to the size of the issuance. Depending on the price at which shares are 
offered, such an issuance could result in dilution in the book value per share to U.S. or other non-
Mexican shareholders or ADS holders not participating in the capital increase.  
Substantial sales of our series A shares or the ADSs could cause the price of our series A shares or the 
ADSs to decrease.  
The market price of our series A shares and the ADSs may decline as a result of sales of a large number of 
series A shares and ADSs or the perception that these sales may occur. These sales, or the possibility that these sales 
may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that 
we deem appropriate.  
Our shareholders, or entities controlled by them or their permitted transferees will be able to sell their shares 
in the public market from time to time without registering them, subject to certain limitations on the timing, amount 
and method of those sales imposed by regulations promulgated by the SEC, as well as any other regulation (including 
anti-trust rules) that may apply. If any of our shareholders, the affiliated entities controlled by them or their respective 
permitted transferees were to sell a large number of their shares, the market price of our series A shares may decline 

 
45 
 
significantly and, as a result, the market price of the ADSs. In addition, the perception in the public markets that sales 
by them might occur may also adversely affect the market price of our series A shares and the ADSs.  
The protections afforded to minority shareholders in Mexico are not as comprehensive as those in other 
jurisdictions, such as the United States.  
Under Mexican law, the protections afforded to minority shareholders and the responsibilities and duties of 
directors and senior officers are different or not as complete as those in the United States. Although Mexican law 
establishes specific duties of care and loyalty applicable to our directors, committee members and senior officers, the 
Mexican legal regime governing directors, committee members and senior officers, and their duties, is not as 
comprehensive or developed as in the United States and has not been the subject of as broad and precise judicial 
interpretation. In addition, the criteria applied in other jurisdictions, including in the United States, to ascertain the 
independence of corporate directors may be different from the criteria applicable under corresponding Mexican laws 
and regulations. Furthermore, in Mexico, there are different procedural requirements for shareholder suits that work 
exclusively for our benefit (such as with respect to derivative suits) and not for the benefit of our shareholders (even 
those that initiate an action). As a result, it may be more difficult in practice for our minority shareholders to enforce 
their rights against us or our directors, committee members or senior officers, including for breach of their duties or 
care or loyalty) than it would be for shareholders of a United States or other non-Mexican company or to obtain 
compensation for minority shareholders, for losses caused by directors, committee members or senior officers as a 
result of a breach of their duties.  
Our bylaws contain provisions aimed at restricting the acquisition of our shares and restricting the 
execution of voting agreements among our shareholders.  
Pursuant to our bylaws, every direct or indirect acquisition of shares, or attempted acquisition of shares, of 
any nature by one or more persons or entities requires the prior written approval by the Board of Directors each time 
that the number of shares to be acquired, when added to any shares already owned by such person or entity, results in 
the acquirer holding 10% or more of our outstanding capital stock. Once such percentage is reached, such person or 
entity must notify our Board of Directors of any subsequent acquisition of shares by any such person or entity through 
which they acquire additional shares representing 2% or more of our outstanding capital stock. Prior, written approval 
must also be requested from our Board of Directors for the execution of written or oral agreements, as a consequence 
of which voting association, block voting, or binding or joint vote mechanisms or covenants are formed or adopted or 
certain shares are combined or shared in any other manner, which effectively results in a change in control of our 
Company or a 20% ownership interest in our Company. No additional authorization is required to carry-out such 
acquisitions or to execute a voting agreement until the ownership percentage of our outstanding capital stock is equal 
to or greater than 20%, nor is any additional authorization required with respect to entering temporary agreements for 
appointment of minority directors.  
If an acquirer does not comply with the procedures described above, such acquired shares or shares 
regarding any voting agreement will not have any voting rights at any shareholders’ meeting of our Company. Any 
such acquired shares which have not been approved by our Board of Directors shall not be registered in our stock 
registry book, entries in our stock registry book made beforehand will be canceled and the Company will not 
acknowledge or give any value to the records or listings referred to in Article 290 of the Mexican Securities Market 
Law (Ley del Mercado de Valores), any other provision that might substitute it from time to time and other applicable 
law. Therefore, such records or listings mentioned above will not be considered evidence of ownership of shares, shall 
not grant the right to attend shareholders’ meetings or validate the exercise of any legal action, including any legal 
action of a procedural nature.  
The provisions in our bylaws described above may only be amended or removed by the approval of 
shareholders holding at least 95% of our shares. This could hinder the process of selling our shares or the execution of 
agreements in connection with those shares.  
These provisions in our bylaws could potentially discourage future purchases of a significant number of our 
shares, including potential future acquirers of our business, and accordingly could adversely affect the liquidity and 
price of our series A shares.  

 
46 
 
The payment and amount of dividends, or share buybacks, are subject to the determination of our 
shareholders.  
The amount available for cash dividends, or share buybacks, if any, will be affected by many factors, 
including our future operating results, financial condition and capital requirements as a result thereof, and the terms 
and conditions of legal and contractual restrictions. Also, the amount of cash available for dividend payments, or 
share buybacks, may vary significantly from estimates. There can be no assurance that we will be able to pay or 
maintain the payment of dividends. Our actual results may differ significantly from the assumptions made by our 
Board of Directors in recommending dividends, or share buybacks, to shareholders or in adopting or amending a 
dividend policy in the future. Also, there can be no assurance that our Board of Directors will recommend a dividend 
payment, or share buy-back, to our shareholders or, if recommended, that our shareholders will approve such a 
dividend payment or share buy-back. The payment of dividends, or share buybacks, and the amounts of dividend 
payments paid by us to our series A shares are subject to the approval of our shareholders and our having absorbed or 
repaid losses from prior years and also may only be paid from retained earnings approved by our shareholders and if 
legal reserves have been created.  
The payment and amount of Vista Argentina’s dividends are subject to certain restrictions from the 
BCRA. 
Pursuant to the Argentine Foreign Exchange Regulations imposed by the BCRA, companies resident in 
Argentina may only have access the foreign exchange market to purchase foreign currency and transfer it abroad for 
the payment of profits and dividends to non-resident shareholders, if certain conditions are met and/or they have the 
prior approval of the BCRA. Although only Vista Argentina’s dividends are subject to the restrictions imposed by the 
BCRA, such restrictions may affect our ability to pay dividends or complete share buybacks because the main source 
of cash generation is in Argentina.  
There can be no assurance that the BCRA will not increase or relax such controls or restrictions, make 
modifications to these regulations, establish more severe restrictions on currency exchange, or maintain the current 
Foreign Exchange Regulations or create multiple exchange rates for different types of transactions, substantially 
modifying the applicable exchange rate at which we acquire currency to service our outstanding liabilities 
denominated in currencies other than the Argentine Peso, all of which could undermine our ability to pay dividends to 
foreign shareholders and to distribute all the net cash flow generated in the form of dividends or buybacks. 
Consequently, these exchange controls and restrictions could materially adversely affect the Argentine economy and 
our business, financial condition and results of operations. See “Item 10—Additional Information—Exchange 
Controls” for additional information. 
Dividend distributions to holders of our series A shares will be made in Mexican Pesos.  
We will make dividend distributions to holders of our series A shares in Mexican Pesos. While the Mexican 
government does not currently restrict the ability of Mexican or foreign persons or entities to convert Mexican Pesos 
into U.S. Dollars or other currencies, it could institute restrictive exchange control policies in the future. Future 
fluctuations in exchange rates and the effect of any exchange control measures adopted by the Mexican government 
on the Mexican economy cannot be predicted.  
If we fail to maintain an effective system of internal control over financial reporting, we may not be able 
to accurately report our financial results or prevent fraud. As a result, shareholders could lose confidence in our 
financial and other public reporting, which would harm our business and the trading price of our common shares. 
Effective internal controls over financial reporting are necessary for us to provide reliable financial reports 
and, together with adequate disclosure controls and procedures, are designed to prevent fraud. Any failure to achieve 
and maintain effective internal controls over financial reporting, implement required new or improved controls, or 
difficulties encountered in their implementation could result in our failure to meet our reporting obligations, which in 
turn could have a material adverse effect on our business and our common shares or the ADSs. In addition, any 
testing by us or any subsequent testing by our independent registered public accounting firm conducted in connection 
with Section 404 of the SOX, may reveal deficiencies in our internal controls over financial reporting that are deemed 
to be material weaknesses or that may require prospective or retroactive changes to our financial statements or

identify other areas for further attention or improvement. Matters impacting our internal controls may cause us to be 
unable to report our financial information on a timely basis and thereby subject us to adverse regulatory 
consequences, including sanctions by the SEC. There also could be a negative reaction in the financial markets due to 
a loss of investor confidence in us and the reliability of our audited financial statements. Confidence in the reliability 
of our audited financial statements also could suffer if we or our independent registered public accounting firm were 
to report a material weakness in our internal controls over financial reporting. This could in turn limit our access to 
capital markets and possibly, harm our results of operations, and lead to a decline in the trading price of our common 
shares or the ADSs. 
Pursuant to Section 404 of the Sarbanes Oxley Act of 2002, we are required to include a report of our 
management on our internal controls over financial reporting in our annual reports on Form 20-F that contains 
management’s assessment relating to the design, maintenance and periodic evaluation of the internal control system, 
accompanied by a report from our independent registered public accounting firm. We can provide no assurance that 
from time to time we will not identify concerns that could require remediation. We may encounter problems or delays 
in completing the implementation of any changes necessary to make a favorable assessment of our internal control 
over financial reporting. An independent assessment of the effectiveness of our internal controls could detect 
problems that our management’s assessment might not. Undetected material weaknesses in our internal controls could 
lead to financial statement restatements and require us to incur the expense of remediation. In connection with the 
attestation process by our independent registered public accounting firm, we may encounter problems or delays in the 
completing the implementation of any requested improvements and receiving a favorable attestation. In addition, if 
we fail to maintain the adequacy of our internal control over financial reporting we will not be able to conclude on an 
ongoing basis that we have effective internal control over financial reporting in accordance with Section 404 which 
may have an adverse effect on us.  
The requirements of being a public company may strain our resources, divert management’s attention 
and affect our ability to attract and retain qualified board members.  
We are required to comply with various regulatory and reporting requirements, including those required by 
the Commission and the CNBV. Complying with these reporting and regulatory requirements is time consuming, 
resulting in increased costs to us or other adverse consequences. As a public company, we are subject to the reporting 
requirements of the Exchange Act, and the requirements of the SOX, in addition to the existing disclosure 
requirements by the Mexican Securities Market Law and CNBV rules. These requirements may place a strain on our 
systems and resources. The Exchange Act rules applicable to us as a foreign private issuer requires that we file annual 
and current reports with respect to our business and financial condition. Likewise, CNBV rules require that we make 
annual and quarterly filings and that we comply with disclosure obligations including current reports. The SOX 
requires that we maintain effective disclosure controls and procedures and internal controls over financial reporting. 
To maintain and improve the effectiveness of our disclosure controls and procedures, we will need to commit 
significant resources, hire additional staff and provide additional management oversight. We will be implementing 
additional procedures and processes for the purpose of addressing the standards and requirements applicable to public 
companies. These activities may divert management’s attention from other business concerns, which could have a 
material adverse effect on our business, results of operations and financial condition.  
Furthermore, we have ceased to be an emerging growth company and are therefore no longer able to take 
advantage of certain exemptions from various requirements applicable to other public companies that are emerging 
growth companies including, most significantly, not being required to comply with the auditor attestation 
requirements of Section 404 of the SOX. As such, our independent registered public accounting firm is now required 
to attest to the effectiveness of our internal control over financial reporting. Even if our management concludes that 
our internal controls over financial reporting are effective, our independent registered public accounting firm may 
decline to attest to our management’s assessment or may issue a report that is qualified if it is not satisfied with our 
controls or the level at which our controls are documented, designed, operated or reviewed, or if it interprets the 
relevant requirements differently from us. Failure to comply with Section 404 could subject us to regulatory scrutiny 
and sanctions, impair our ability to raise revenue, cause investors to lose confidence in the accuracy and completeness 
of our financial reports and negatively affect our share price.

Our bylaws, in compliance with Mexican law, restrict the ability of non-Mexican shareholders to invoke 
the protection of their governments with respect to their rights as shareholders.  
As required by Mexican law, our bylaws provide that non-Mexican shareholders are considered to be 
Mexican with respect to shares held by them. Moreover, non-Mexican shareholders explicitly agree not to invoke the 
protection of its own government by asking such government to interpose a diplomatic claim against the Mexican 
government with respect to the shareholder’s rights as a shareholder, though such agreement is not deemed to include 
a waiver to any other rights (for instance, any rights under the United States securities laws, with respect to its 
investment in us). If you invoke such governmental protection in violation of this provision of the bylaws, your series 
A shares may be forfeited to the Mexican government.  
As a foreign private issuer, we are permitted to, have relied, and intend to keep relying, on exemptions 
from certain NYSE corporate governance standards applicable to U.S. issuers. This may afford less protection to 
holders of the ADSs.  
The NYSE’s rules require listed companies to have, among other things, a majority of their board members 
be independent and to have independent director oversight of executive compensation, nomination of directors and 
corporate governance matters. While we currently meet this requirement, we might cease to do so in the future, given 
that, as a foreign private issuer and a controlled company, we are permitted to follow home country practice in lieu of 
the above requirements. Mexican law does not require that a majority of our board consist of independent directors or 
the implementation of a compensation or nominating committee, and our board may thus not include, or include 
fewer, independent directors than would be required if we were subject to the NYSE rules applicable to most U.S. 
companies. As long as we rely on the foreign private issuer and controlled company exemptions to the NYSE rules, a 
majority of our Board of Directors is not required to consist of independent directors and we will not be required to 
have a compensation or nominating committee. Therefore, our board’s approach may be different from that of a board 
with a majority of independent directors, and, as a result, the Executive Team’s oversight of the Company may be 
more limited than if we were subject to the NYSE rules applicable to most U.S. companies.  
It may be difficult to enforce civil liabilities against us or our directors or officers.  
We are a publicly traded company with variable capital (sociedad anónima bursátil de capital variable) 
organized under the laws of Mexico, and a majority of the members of our Board of Directors and Executive Team, 
our advisors and independent auditors reside or are based outside the United States. All of our assets and the assets of 
our subsidiaries are located, and all of our revenues and the revenues of our subsidiaries are derived from, sources 
outside the United States, particularly in Mexico and Argentina. Consequently, it may not be possible for you to effect 
service of process upon us or these other persons. Because judgments of U.S. courts or courts of other jurisdictions 
outside of Mexico and/or Argentina for civil liabilities based upon foreign laws of other jurisdictions outside Mexico 
and/or Argentina may only be enforced in Mexico and/or Argentina if certain requirements are met, you may face 
greater difficulties in protecting your interests through actions against us, our directors or the members our Executive 
Team than would shareholders of a corporation incorporated in the United States or in other jurisdictions outside of 
Mexico. There is doubt as to the enforceability, in original actions in Mexican courts and/or Argentine courts or in 
actions for enforcement of judgments obtained in courts of jurisdictions outside Mexico and/or Argentina, of 
liabilities predicated, in whole or in part, on the civil liability provisions of U.S. federal securities laws. No treaty 
exists between the United States and Mexico for the reciprocal enforcement of judgments issued in the other country. 
In addition, the enforceability in Argentine courts of judgments of U.S. or non-Argentine courts with respect to 
matters arising under U.S. federal securities laws or other non-Argentine regulations will be subject to compliance 
with certain requirements under Argentine law, including the condition that any such judgment does not violate 
Argentine public policy (orden público argentino) and provided that an Argentine court will not order the attachment 
on any property located in Argentina and determined by such court to be essential for the provision of public services.  
ADSs holders may not be entitled to a jury trial with respect to claims arising under the deposit 
agreement, which could result in less favorable outcomes to the plaintiff(s) in any such action.  
The deposit agreement governing the ADSs representing our ordinary shares provides that, to the fullest 
extent permitted by law, holders and beneficial owners of ADSs irrevocably waive the right to a jury trial of any 
claim they may have against us or the depositary arising out of or relating to the ADSs or the deposit agreement. If 
this jury trial waiver provision is not permitted by applicable law, an action could proceed under the terms of the 

 
49 
 
deposit agreement with a jury trial. If we or the depositary opposed a jury trial demand based on the waiver, the court 
would analyze whether the waiver was enforceable based on the facts and circumstances of that case in accordance 
with the applicable state and federal law. In determining whether to enforce a contractual pre-dispute jury trial waiver 
provision, courts will generally consider whether a party knowingly, intelligently and voluntarily waived the right to a 
jury trial. We believe that this is the case with respect to the deposit agreement and the ADSs. It is advisable that you 
consult legal counsel regarding the jury waiver provision before entering into the deposit agreement.  
If you or any other holders or beneficial owners of ADSs bring a claim against us or the depositary in 
connection with matters arising under the deposit agreement or the ADSs, including claims under federal securities 
laws, you or such other holder or beneficial owner may not be entitled to a jury trial with respect to such claims, 
which may have the effect of limiting and discouraging lawsuits against us and / or the depositary. If a lawsuit is 
brought against us and/or the depositary under the deposit agreement, it may be heard only by a judge or justice of the 
applicable trial court, which would be conducted according to different civil procedures and may result in different 
outcomes than a trial by jury would have had, including results that could be less favorable to the plaintiff(s) in any 
such action, depending on, among other things, the nature of the claims, the judge or justice hearing such claims, and 
the venue of the hearing.  
No condition, stipulation or provision of the deposit agreement or ADSs serves as a waiver by any holder or 
beneficial owner of ADSs or by us or the depositary of compliance with any substantive provision of the U.S. federal 
securities laws and the rules and regulations promulgated thereunder.  
Holders of our series A shares who sell or transfer series A shares acquired after January 1, 2018 and 
representing 10% or more of our equity may be subject to Argentine capital gains tax under Argentine tax law.  
Under Argentine tax law, non-Argentine residents who sell or transfer shares or other interests in foreign 
entities acquired after January 1, 2018, may be subject to capital gains tax in Argentina if 30% or more of the market 
value of the foreign entity is derived from assets located in Argentina and the shares being sold or transferred 
represent 10% or more of the equity interests of such foreign entity. Therefore, any non-Argentine holder of our series 
A shares who sell or transfer series A shares acquired after January 1, 2018, representing 10% or more of our equity 
interests would be subject to the Argentine capital gains tax.

Recent Developments 
Corporate Reorganization 
 
On December 20, 2024, the Board of Directors of Vista Argentina, Aleph Midstream, and Vista Holding VII 
S.A.U., along with the management (Gerencia) of AFBN, approved a preliminary merger agreement (“Preliminary 
Agreement”), pursuant to which the latter three entities will be absorbed by and merged into our subsidiary Vista 
Argentina, as the surviving entity (“Merger”). The Preliminary Agreement establishes January 1, 2025, as the 
effective date of the Merger. The Merger has been undertaken for intragroup corporate reorganization purposes. 
 
For Argentine tax purposes, as provided in Section 80 of the ITL (as defined below), the effective date of a 
merger determines the date from which the entities are considered to be operating jointly. 
 

 
50 
 
For Argentine corporate law purposes, a merger becomes effective only upon its registration with the public 
registry. As of the date of this annual report, the Merger has not yet been registered with the public registry. Upon 
registration, the effective date for Argentine corporate law purposes will be determined, and Vista Argentina will 
consolidate all assets and operations of AFBN, Aleph Midstream, and Vista Holding VII S.A.U. 
 
Additionally, under the Argentine General Companies Law No. 19,550 (Ley General de Sociedades), the 
Preliminary Agreement remains preliminary because it does not yet include the approval of the consolidated and 
individual financial statements of the merged entities, which must be approved jointly with the pre-merger agreement. 
As of the date of this annual report, the execution of the pre-merger agreement between Vista Argentina, AFBN, 
Aleph Midstream and Vista Holding VII S.A.U. and the approval of the related merger financial statements remain 
pending. According to Section 83 of the Argentine General Companies Law, a pre-merger agreement must be 
approved, which includes the approval of the financial statements mentioned above (“Pre-Merger Agreement”). This 
Pre-Merger Agreement was approved by the Board of Directors of all four entities on March 28, 2025, including the 
approval of consolidated merger financial statements with a cut-off date of December 31, 2024. Additionally, under 
the Argentine General Companies Law, the Pre-Merger Agreement must be approved by the shareholders’ meetings 
of the involved entities. The shareholders’ meetings of Vista Argentina, AFBN, Aleph Midstream, and Vista Holding 
VII S.A.U. have been scheduled for April 28, 2025. 
 
Consequently, while Vista Argentina, AFBN, Aleph Midstream, and Vista Holding VII S.A.U. are currently 
operating jointly, the Merger remains subject to the satisfaction of certain conditions precedent, including the 
execution of the pre-merger agreement and its registration with the public registry. 
 
Addition of a New Member to the Management Team 
 
Effective January 14, 2025, Matías Weissel has been appointed as Chief Operations Officer of Vista, 
replacing Juan Garoby, who has transitioned to the role of Chief Technology Officer. Mr. Weissel has served as Vista 
Argentina’s Operations Manager since January 2023 and has been with the Company since the commencement of 
operations in April 2018. Mr. Garoby has held the position of Chief Operations Officer since August 2017 and has 
been involved with the company since its incorporation on March 22, 2017. 
 
Farm-out Agreements  
 
On December 16, 2024, Vista Argentina agreed to the assignment of Trafigura’s interest in the Farm-out 
Agreements (as defined below), to Vista Argentina, effective January 1, 2025 (“Trafigura Agreement”). Since 
effectiveness, Vista Argentina holds rights to 100% of the production from the pads subject to the Trafigura 
Agreement. Under the Trafigura Agreement, Vista Argentina will pay Trafigura US$128 million in 48 consecutive 
monthly installments through December 2028.  
 
Additionally, Vista Argentina and Trafigura entered into a crude oil marketing agreement, effective from 
January 1, 2025, to December 31, 2028, pursuant to which Vista Argentina will sell 10,000 m³ of crude oil per month 
to Trafigura. The amounts payable by Trafigura under the crude oil marketing agreement will be offset against Vista 
Argentina’s obligations under the Trafigura Agreement.  
 
As of December 31, 2024, the Trafigura Agreement had no accounting impact on the consolidated financial 
statements. 
 
For more information on the Farm-out Agreements, see “—Business Overview—Argentina—Concessions.” 
 
BUSINESS OVERVIEW  
We are an independent Latin American, shale oil-focused company operating since April 4, 2018, with our 
main assets located in the Vaca Muerta play in the Neuquina basin, Argentina. Vaca Muerta is the largest shale oil 
and gas play under development outside North America, where we have rights to develop approximately 205,600 
acres. We are also the holders of one conventional producing asset in Mexico. Most of our production and revenues, 
our ongoing drilling and workover activities, estimated proved reserves and assets are located in Argentina, including 
our currently producing Vaca Muerta wells.  

 
51 
 
We seek to generate strong returns for our shareholders based on the following key value drivers: 
Deep, ready-to-drill, short-cycle well inventory. Our growth plan is based on developing our inventory of 
approximately 1,150 wells in Vaca Muerta, out of which 550 well are in Bajada del Palo Oeste, 150 in Bajada del 
Palo Este, 150 in Aguada Federal, 150 in Bandurria Norte, 100 in Águila Mora and 50 in Coirón Amargo Norte. 
Additionally, as of December 31, 2024, the number of cumulative shale wells we had tied-in increased to 117 in 
Bajada del Palo Oeste, 17 in Bajada del Palo Este, 13 wells in Aguada Federal and two wells in Águila Mora, for a 
total of 149 cumulative shale wells tied-in in Vaca Muerta. This activity boosted our production to 85.3 Mboe/d 
during the fourth quarter of 2024. Our proved certified reserves increased to 375.2 Mboe as of December 31, 2024.  
Peer-leading operating performance.  We believe the productivity of our wells reflects the quality of our 
Vaca Muerta acreage and our of operational capabilities, in line with the highest efficiency and safety standards. As of 
December 31, 2024, the cumulative production of the average Vista well after 720 days on production (represented by 
the wells in pads BPO-1 to BPO-14) was performing 6% above our Bajada del Palo Oeste type curve. This 
performance places our wells among the best in Vaca Muerta. In addition, the dilution of fixed costs as we increase 
production and our rebased cost structure following our decision to focus on shale oil have led to a decrease in lifting 
costs from US$13.9/boe in 2018 to US$4.6/boe in 2024.  
Robust balance sheet and financial performance. Based on a benchmarking analysis against peers in the 
Argentine, Latin American and U.S. shale energy spaces, we believe we are a Company with a history of 
comparatively low debt leverage ratios, high Adjusted EBITDA Margins and high ROACE. Cash and cash 
equivalents at the end of 2024 was US$764.3 million. During the year 2024, net income for the year totaled US$477.5 
million. The Adjusted EBITDA for 2024 was US$1,092.4 million resulting in an Adjusted EBITDA Margin of 65%. 
Additionally, net leverage ratio as of December 31, 2024, was 0.63x Adjusted EBITDA and ROACE was 24% for 
2024. 
ESG-focused culture. We aim to develop our business in a sustainable way. We aspire to reduce our 
operating scope 1 and 2 GHG emission intensity by more than 80% to 7 kgCO2e/boe in 2026, compared to 39 
kgCO2e/boe in 2020. During 2024, we reduced the intensity of scope 1 and 2 GHG emissions by 44% year-over-year, 
from 15.6 kgCO2e/boe to 8.8 kgCO2e/boe. We are also executing a portfolio of NBS projects through our subsidiary 
Aike, in Argentina. By 2026, we expect to have generated enough carbon credits through our NBS projects to offset 
the residual emissions from our operations, thereby becoming net zero in scope 1 and 2 GHG emissions. 
Safety is a bedrock of our Company, and we aim to operate with the highest oil and gas industry standards in 
accordance with the International Association of Oil and Gas Producers (“IOGP”) and the global oil and gas industry 
association for environmental and social issues (“IPIECA”). In 2024, we had a TRIR of 0.6 which was below 1.0 for 
the fifth consecutive year. Furthermore, in 2024 we recorded no major oil spill incidents. For further information on 
ESG matters, see “—ESG Matters.”

As of December 31, 2024, our portfolio of assets included six operated blocks in Vaca Muerta (holding 
approximately 205,600 net shale oil acres), one operated conventional block in Mexico and one non-operated 
conventional block in Argentina. Additionally, effective March 1, 2023, Vista transferred the operatorship of six 
conventional blocks to Aconcagua. See “—Transaction to Increase Focus on Shale Oil Operations in Vaca Muerta.”  
During 2024, our average daily production was 69.7 Mboe/d. Additionally, as of December 31, 2024, our 
total proved reserves were 375.2 MMboe, of which 86% consisted of oil and 97% of which were located in 
Argentina. During the fourth quarter of 2024, our total production was 85.3 Mboe/d and our shale production was 
80.1 Mboe/d. We were the third largest oil operator in Argentina, and the second largest in Vaca Muerta, according to 
the SdE.

Muerta.”  
 
Transaction to Increase Focus on Shale Oil Operations in Vaca Muerta 
On February 23, 2023, Vista announced a two-phase transaction (“Conventional Assets Transaction”) 
between Vista Argentina and Petrolera Aconcagua Energía S.A. (“Aconcagua”) to increase its focus on its shale oil 
operations in Vaca Muerta and strengthen shareholder returns.  
Under the terms of the Conventional Assets Transaction, effective March 1, 2023: 
(i) 
Aconcagua became the operator of the following exploitation concessions in the Neuquina Basin 
located in Argentina: Entre Lomas, located in the Province of Neuquén, and Entre Lomas, Jarilla 
Quemada, Charco del Palenque, Jagüel de los Machos and 25 de Mayo–Medanito, located in the 
Province of Río Negro (“CAT Exploitation Concessions”). Additionally, Aconcagua became the 
operator of the following transportation concessions: the Entre Lomas gas transportation 
concession, the Jarilla Quemada gas transportation concession, and the 25 de Mayo–Medanito crude 
oil transportation concession (“CAT Transportation Concessions,” and together with the CAT 
Exploitation Concessions, the “CAT Concessions”); 
 
(ii) 
Aconcagua paid Vista US$26.47 million in cash (US$10.00 million paid on February 15, 2023, 
US$10.73 million paid on March 1, 2024, US$5.73 million paid on February 28, 2025);  
 
(iii) 
Vista Argentina retains 40% of the crude oil and natural gas production, and 100% of liquified 
petroleum gas, gasoline, and condensates, from the CAT Exploitation Concessions (with 
Aconcagua paying all costs, taxes, and royalties) until the earlier of (a) the final closing date on 
February 28, 2027 and (b) the date in which Vista Argentina receives a cumulative production of 
4 million barrels of crude oil and 300 million m3 of natural gas. On the other hand, Aconcagua is 
entitled to 60% of the crude oil and natural gas production from the CAT Exploitation Concessions; 
 
(iv) 
Aconcagua will pay 100% of Vista Argentina’s share of the capex, opex, royalties, taxes, and any 
other costs associated with the CAT Exploitation Concessions; 
 
(v) 
Vista Argentina has the right to purchase from Aconcagua up to Aconcagua’s 60% share of the 
natural gas produced by the CAT Exploitation Concessions at a price of US$1 per million Btu until 
the final closing date on February 28, 2027;  
 
(vi) 
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 CAT 
Concessions, including an upfront payment and an investment commitment, as per the terms set 
forth in the applicable regulation in Argentina; 
 
(vii) 
Vista Argentina retains the right to explore and develop the Vaca Muerta formation in the CAT 
Exploitation Concessions and seek to obtain one or more independent and separate unconventional 
concessions to develop such resources; 
 
(viii) 
Vista Argentina and Aconcagua have signed an agreement whereby Vista Argentina will treat and 
transport 100% of the crude oil produced in the CAT Exploitation Concessions (except for 25 de 

 
54 
 
Mayo–Medanito and Jagüel de los Machos) until the expiration of the concession titles (including 
the potential 10-year extension); and 
 
(ix) 
Vista Argentina remains concession title holder until no later than the final closing date on February 
28, 2027, when the CAT Concessions will be transferred to Aconcagua, subject to provincial 
approvals. 
The Entre Lomas crude oil transportation concession, which includes an oil treatment plant geographically 
located in the Entre Lomas Río Negro concession and a net book value of US$20 million as of December 31, 2022, 
was excluded from the Conventional Assets Transaction.  
In December 2024, Vista Argentina and Aconcagua entered into an amendment to the terms of the 
Conventional Assets Transaction, effective October 1, 2024, that included the transfer of ownership of the 60% share 
of the natural gas produced by the CAT Exploitation Concessions from Aconcagua to Vista Argentina. Under the 
original agreement, this share in natural gas production was held by Aconcagua and sold to Vista at a fixed price of 
US$1 per million Btu. As a result of the amendment, starting on October 1, 2024, Vista Argentina retains (a) 40% of 
crude oil production and reserves and (b) 100% of natural gas, liquefied petroleum gas, gasoline, and condensate 
production and reserves, in both cases with respect to the CAT Exploitation Concessions. 
Vaca Muerta Sur Project 
On December 16, 2024, Vista Argentina announced its participation as a shareholder in VMOS S.A. 
(“VMOS”), alongside YPF, Pampa Energía S.A., and Pan American Sur S.A., in connection with the Vaca Muerta Sur 
Project. Between December 20, 2024 and March 7, 2025, Pluspetrol S.A., Chevron (through two subsidiaries), Shell 
(through two subsidiaries) and Gas y Petróleo del Neuquén S.A. also confirmed their participation as shareholders in 
VMOS (collectively, the “VMOS Shareholders”). 
On December 13, 2024, Vista Argentina, YPF, Pampa Energía S.A., and Pan American Sur S.A. 
unanimously approved the construction of the Vaca Muerta Sur crude oil export pipeline (“VMOS Project”). The 
VMOS Project is expected to span approximately 437 kilometers and will include a loading and unloading terminal 
with interconnected monobuoys, as well as a tank and storage yard. 
The VMOS Project is expected to have an initial transportation capacity of up to 550,000 bbl/d during 
commercial operations, with the potential to expand to 700,000 bbl/d if required (“VMOS Project Expansion”). 
According to the current construction schedule, commercial operations are expected to commence in the second half 
of 2027. The VMOS Shareholders have committed an aggregate volume of approximately 450,000 bbl/d of capacity. 
The estimated total investment required for the VMOS Project is approximately US$3 billion, which is 
expected to be financed through capital contributions from the VMOS Shareholders and third-party financing to be 
secured by VMOS during 2025. 
Vista Argentina holds a minority equity interest in VMOS and has secured firm transportation, storage, and 
dispatch capacity in the VMOS Project for 50,000 bbl/d, with an option to increase its capacity allocation in the event 
of the VMOS Project Expansion. 
VMOS intends to develop the VMOS Project under the “Incentive for Large Investments Framework” 
(“RIGI” for its acronym in Spanish), in accordance with the provisions of the Ley de Bases, Decree No. 794/2024, and 
other applicable Argentine regulations. On March 20, 2025, the VMOS Project was approved under RIGI and, 
therefore, classified as a “strategic long-term export project.”  
Additionally, on December 13, 2024, Vista Argentina entered into a firm crude oil transportation agreement 
with VMOS under the terms of Decree No. 115/2019, securing the terms and conditions for the transportation, 
storage, and dispatch of crude oil.

Argentina  
Overview  
During the year ended December 31, 2024, our production was concentrated in the Neuquina Basin, mostly 
in our development hub in Vaca Muerta.  
We have approximately 205,600 net acres located in the Vaca Muerta shale oil formation in six concessions: 
Bajada del Palo Oeste, Bajada del Palo Este, Águila Mora, Aguada Federal, Bandurria Norte and Coirón Amargo 
Norte. We operate 100% of our shale net acreage. As of December 31, 2024, we had tied-in 117 shale oil wells 
targeting the Vaca Muerta formation in Bajada del Palo Oeste, 17 wells in Bajada del Palo Este, 13 wells in Aguada 
Federal, and two wells in Águila Mora. This brought our shale production to 64.1 Mboe/d during 2024, up from 43.3 
Mboe/d in 2023, boosted by strong individual well performance.  
We have a significant inventory of up to approximately 1,150 ready-to-drill, short-cycle, drilling locations 
targeting the Vaca Muerta shale oil formation within our core development acreage, which provides us with more 
than 15 years of drilling inventory at the current drilling pace. Our drilling inventory is currently located in the Bajada 
del Palo Oeste, Bajada del Palo Este, Aguada Federal, Bandurria Norte, Águila Mora and Corión Amargo Norte 
blocks. We intend to expand our drilling inventory by testing additional landing zones. See “—Drilling Activities.” 
As of December 31, 2024, we also owned working interests in non-operated conventional assets in the 
Noroeste Basin. As a result of the Conventional Assets Transaction, we transferred the operations of six conventional 
assets in the Neuquina basin, effective March 1, 2023. See “—Transaction to Increase Focus on Shale Oil Operations 
in Vaca Muerta.” 
As of December 31, 2024, our total proved reserves in Argentina were 365.5 MMboe, of which 86% 
consisted of oil reserves. Our average daily production for the year ended December 31, 2024, was 69.0 Mboe/d, of 
which 86.6% was crude oil, 12.9% natural gas and the remaining 0.4% was NGL. We have reduced our average 
lifting cost from US$5.1 per boe during the year ended December 31, 2023, to US$4.6 per boe for the year ended 
December 31, 2024.

Concessions  
Our Argentine concession agreements have no change of control provisions, though any assignment of these 
concessions is subject to the prior authorization by the provincial executive branch where the concession is located. 
For the four years prior to the expiration of each of these concessions, the concession holder must provide technical 
and commercial justifications for leaving any inactive and non-producing wells unplugged. Each of these concessions 
can be terminated for default in payment obligations and/or breach of material statutory or regulatory obligations. We 
may also voluntarily relinquish acreage to the Argentine authorities.  
As of the date of this annual report, we have working interests in the following oil and gas concessions in 
Argentina:  
Bajada del Palo Oeste  
Bajada del Palo Oeste has 62,641 gross acres with exposure to core shale oil in the Vaca Muerta acreage. 
Our current drilling inventory targeting the Vaca Muerta shale oil formation amounts to up to 550 locations located in 
this concession. We intend to expand such drilling inventory by testing additional stacked pay zones.  
We are the operator and holder of 100% of the unconventional exploitation concession granted for the 
Bajada del Palo Oeste block in the Neuquina Basin located in the Province of Neuquén. This block has proved 
reserves of 240.7 MMboe of shale reserves and 1.5 MMboe of conventional reserves as of December 31, 2024, and 
production of 52.8 Mboe/d (87% representing oil) for the year ended December 31, 2024. The 35-year term 
unconventional exploitation concession was granted to us in December 2019 and expires on December 19, 2053. In 
connection with the granting of such unconventional concession, as of December 31, 2024, we have already fulfilled 
the commitment to drill eight horizontal wells for a total investment of US$105.6 and US$14.7 million related 
facilities.  
During 2024, we completed and tied-in nine pads (pad BPO-22 to BPO-30), adding 34 shale oil wells and 
taking the shale oil well count in Bajada del Palo Oeste to 117 at year-end 2024. Total shale production in 2024 
increased to 64.1 Mboe/d, out of which 52.2 Mboe/d corresponds to the shale production of Bajada del Palo Oeste. 
We believe the productivity of our wells demonstrate the quality of our Vaca Muerta acreage. As of December 
31, 2024, the cumulative production of our average well after 720 days on production (represented by the wells in 
pads BPO-1 to BPO-14) was performing 6% above our Bajada del Palo Oeste type curve.  

 
58 
 
 
 
(1) Normalized to a standard well design of 2,800 meters lateral length and 47 frac stages well 
(2) Normalized average cumulative production of wells in pads BPO-1 to BPO-30 for 90 days, pads BPO-1 to BPO-21 for one year, and pads 
BPO-1 to BPO-15 for two years. Excludes cube development pilot in pads BPO-16 and BPO-17 
 
Additionally, the 90-day performance of our first 90 wells compares favorably with horizontal oil wells 
drilled in Vaca Muerta and tied in since 2012, as shown in the charts below. We believe this reflects the quality of our 
acreage and our leading operating performance among peers. 
 
 
 
On June 28, 2021, Vista Argentina formed an unincorporated joint venture with Trafigura for the joint 
development of five pads, each consisting of four wells at Bajada del Palo Oeste, effective July 1, 2021 (“Farm-out 
Agreement I”). Under the Farm-out Agreement I, Trafigura has a contractual right to 20% of the hydrocarbon 
production and an obligation to cover 20% of the capital expenditures, royalties, and direct taxes. In turn, Trafigura 
paid Vista Argentina a total of US$25,000,000 in instalments and a fee for various costs. Vista Argentina retains 80% 
of the hydrocarbon production rights and born 80% of the associated costs. Trafigura also had an option to participate 
in two additional pads under similar terms. As of the date of this annual report, seven pads comprising 28 wells have 
been completed under Farm-out Agreement I. 
 
On October 11, 2022, Vista Argentina entered into a similar joint venture with Trafigura for the development 
of three additional pads at Bajada del Palo Oeste, effective October 1, 2022 (“Farm-out Agreement II,” and together 
with Farm-out Agreement I, the “Farm-out Agreements”). Under Farm-out Agreement II, Trafigura has contractual 
right to 25% of the hydrocarbon production and an obligation to cover 25% of the capital expenditures and related 
costs, royalties, and direct taxes. In turn, Trafigura also agreed to pay Vista Argentina US$1,700,000 per tied-in well 
and additional fees based on production and crude oil price improvements. Vista retains 75% of the production rights 
and born 75% of the costs. The Farm-out Agreement II also extended a crude oil sales and purchase agreement with 
Trafigura. As of the date of this annual report, three pads with 12 wells have been completed under Farm-out 
Agreement II. 

 
59 
 
 
On December 16, 2024, Vista Argentina agreed to assume Trafigura’s interest in the Farm-out Agreements, 
effective January 1, 2025. As a result, as of the date of this annual report, Vista Argentina holds rights to 100% of the 
production from the pads subject to the terms in the Trafigura Agreement. See “—Recent Development—Farm-out 
Agreements.” 
 
Bajada del Palo Este  
We are the operator and holder of 100% of the exploitation concession granted for the Bajada del Palo Este 
block in the Neuquina Basin located in the Province of Neuquén. Bajada del Palo Este has 48,853 gross acres with 
exposure to shale oil Vaca Muerta acreage. We estimate there are up to 150 new well locations to be drilled in this

this block. 
Aguada Federal 
Aguada Federal is an unconventional exploitation concession in the Neuquina Basin located in the Province 
of Neuquén, covering approximately 24,058 gross acres. On September 16, 2021, we acquired a 50% non-operated 
working interest in Aguada Federal from ConocoPhillips Petroleum Holdings B.V. (“ConocoPhillips”) On January 
17, 2022, we acquired an additional 50% non-operated working interest from Wintershall DEA Argentina S.A. and, 
therefore, as of such date, we became the operator and sole concession holder of the block.  
As of December 31, 2024, we had tied-in 13 shale wells on the block. The block had proved reserves of 45.1 
MMboe as of December 31, 2024, and production of 4.8 Mboe/d (72% representing oil) for the year ended December 
31, 2024. We estimate that there are up to 150 new well locations to be drilled in this block. The concession expires 
on December 20, 2050. As of the date of this annual report, we have no pending commitments in this block. 
Águila Mora 
We are the operator and holder of a 90% participation interest in the unincorporated joint venture with Gas y 
Petróleo del Neuquén S.A. (“G&P”) (which owns the remaining 10% participation interest) for the unconventional 
exploitation concession over the Águila Mora block in the Neuquina Basin located in the Province of Neuquén, which 
covers approximately 23,475 gross acres. The block had proved reserves of 0.5 MMboe as of December 31, 2024, and 
production of 0.9 Mboe/d (72% representing oil) for the year ended December 31, 2024. We estimate there are up to 
100 new well locations to be drilled in this block. 
On November 29, 2019, the Province of Neuquén issued the Decree No. 2597 pursuant to which G&P was 
granted an unconventional exploitation concession over the Águila Mora block for a term of 35 years (renewable 
upon termination and subject to certain conditions for successive 10-year extensions) in replacement of the existing 
exploration permit over the block. 
G&P holds the mining rights over Águila Mora. Vista (i) holds a 90% working interest in a joint venture 
with G&P for the E&P of the hydrocarbons in Águila Mora; and (ii) is the operator of Águila Mora. 
The abovementioned unconventional exploitation concession includes the commitment to perform an initial 
pilot, during which Vista committed to (i) return to production three wells previously drilled and completed by the 
former operator, (ii) drill two new horizontal wells, and (iii) build surface facilities, for a total investment of 

 
60 
 
approximately US$32.8 million. As of the date of this annual report, we have no pending commitments. The 
concession expires on November 28, 2055.  
Bandurria Norte 
Bandurria Norte is an unconventional exploitation concession in the Neuquina Basin located in the Province 
of Neuquén, which covers approximately 26,404 gross acres. On September 16, 2021, we acquired a 50% non-

extension in favor of Vista Argentina for its non-operated conventional exploitation concessions in the following 
areas: (i) Entre Lomas and 25 de Mayo–Medanito SE, together with their associated transportation concessions, each 
extended until 2036; and (ii) Jagüel de los Machos, extended until 2035. In connection with the extension of these 
concessions, the Company assumed additional investment commitments, as described below. 
As of the date of this annual report, the Company had the following pending commitments, including those 
assumed under the terms of the above-mentioned concession extensions. In Entre Lomas, Río Negro, the Company is 
committed to drilling and completing four development wells with an estimated cost of US$10.5 million, making 
capital investments in 21 well workovers and abandoning two wells for an estimated cost of US$7.0 million, and 

 
61 
 
adjusting new and existing facilities for an estimated cost of US$3.1 million. In 25 de Mayo–Medanito SE and Jagüel 
de los Machos, the Company is committed to drilling and completing five development wells with an estimated cost 
of US$7.7 million, making capital investments in 23 well workovers and abandoning 19 wells for an estimated cost of 
US$10.0 million, and adjusting new and existing facilities for an estimated cost of US$1.4 million. Pursuant to the 
Conventional Assets Transaction Agreement, Aconcagua has assumed all investment commitments, as well as costs, 
taxes, and royalties related to the CAT Exploitation Concessions.  
Vista retains the right to explore and develop the Vaca Muerta formation in the CAT Exploitation 
Concessions and seek to obtain one or more independent and separate unconventional concessions to develop such 
resources.

Mexico  
CS-01 Block  
We hold a 100% interest in the license agreement entered into with CNH for block CS-01, which we operate. 
The block covers approximately 14,332 gross acres and is located in the state of Tabasco. As of December 31, 2024, 
the block had proved reserves of 9.8 MMboe. During 2024, average production of CS-01 was 0.6 Mboe/d (97% 
representing oil). This license agreement will terminate in 2047. As of the date of this annual report, we have no 
pending investment commitments. 
Oil and Natural Gas Reserves  
Reserves  
The information included in this annual report regarding proved reserves is derived from estimates of the 
proved reserves as of December 31, 2024, in the 2024 Reserves Report prepared by D&M. The 2024 Reserves Report 
is included as Exhibit 99.1 to this annual report. 
D&M is an independent reserves engineering consultant. The 2024 Reserves Report is based on information 
provided by us and presents an appraisal as of December 31, 2024, of oil and gas reserves located in the Entre Lomas 
Río Negro, Entre Lomas Neuquén, Bajada del Palo Oeste, Bajada del Palo Este, Charco del Palenque, Jarilla 
Quemada, Coirón Amargo Norte, Acambuco, Jagüel de los Machos, 25 de Mayo–Medanito SE, Aguada Federal, 
Águila Mora and Bandurria Norte blocks in Argentina and of our oil and gas reserves located in the CS-01 block in 
Mexico. 
We believe our evaluators’ estimates of remaining proved recoverable oil and gas reserve volumes to be 
reasonable. Pursuant to Rule 4-10 of Regulation S-X, promulgated by the SEC, proved oil and gas reserves are those 
quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable 
certainty to be economically producible-from a given date forward, from known reservoirs, and under existing 
economic conditions, operating methods, and government regulations-prior to the time at which contracts providing 
the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether 
deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have 
commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.  
The Company considers that its remaining estimated volumes of oil and gas proved recoverable reserves are 
fair and that these estimates were prepared according to SEC regulations and ASC 932, as amended. Consequently, 
crude oil prices used in determining proved reserves were the average price during the 12 months prior to the end date 
of December 31, 2024, and 2023, respectively, determined as an unweighted average of the first day of the month for 
each month within these periods. Moreover, since there are no natural gas prices available in the benchmark market in 
Argentina, we used the average gas prices for the previous year to determine gas reserves. In addition, for certain gas 

 
62 
 
volumes, Vista will obtain an incentive price subsidized by the Argentine government through Plan GasAr round. A 
weighted average price is estimated for certain areas per subsidized and unsubsidized volume. 
The following table sets forth summary information about the oil and natural gas net proved developed and 
undeveloped reserves of the assets owned by Vista in Argentina and Mexico as of December 31, 2024. The proved 
developed and undeveloped reserves estimates included below were calculated at their respective working interest

Total figures may not add up due to rounding.  
(1) Our hydrocarbon liquid volumes include crude oil, condensate and NGL (LPG and natural gasoline). We do not include separate 
figures for NGL reserves because they represented less than 1% of our proved developed and undeveloped reserves as of December 
31, 2024, respectively. 
(2) Natural gas consumption represented 9% of total natural gas reserves (consumption plus natural gas sales) as of December 31, 2023, 
and 12% as of December 31, 2024.  
 
As of December 31, 2024, the oil and gas proved reserves of the assets we own (developed and undeveloped) 
totaled 375.2 MMboe (322.6 MMbbl of oil, condensate and NGL and 295.7 Bncf, or 52.7 MMboe of gas). Proved 
undeveloped reserves of crude oil, condensate and NGL represented 57% of our total proved reserves.

(1) Our hydrocarbon liquid volumes include crude oil, condensate and NGL (LPG and natural gasoline). We do not include separate 
figures for NGL reserves because they represented less than 1% of our proved developed and undeveloped reserves as of December 
31, 2024. 
(2) Natural gas consumption represented 9% of total natural gas reserves (consumption plus natural gas sales) as of December 31, 2023, 
and 12% as of December 31, 2024. 
 
Changes in our proved undeveloped reserves during 2024 
As of December 31, 2024, we had an estimated volume of proved undeveloped reserves of 246.0 MMboe. 
This compares to an estimate of proved undeveloped reserves of 229.7 MMboe as of December 31, 2023. The total 
increase of 16.3 MMboe (+16.6 MMbbl of crude oil, condensate and NGL and -2.09 Bcf of natural gas) in proved 
undeveloped reserves in 2024 is attributable to:  
Argentina: 
• 
An increase of 53.16 MMboe (+48.04 of crude oil, condensate and NGL and +28.75 Bcf of natural gas) 
due to extensions and discoveries, mainly related to the drilling activity targeting the Vaca Muerta 
formation in: (a) the Aguada Federal concession (+4.11 MMbbl of crude oil, condensate and NGL and 
+3.48 Bcf of natural gas), (b) the Bajada del Palo Este concession (+24.9 MMbbl of crude oil, condensate 
and NGL and +12.55 Bcf of natural gas) and (c) the Bajada del Palo Oeste concession (+19.64 MMbbl of 
crude oil, condensate and NGL and +12.72 Bcf of natural gas); 
 
• 
A decrease of 35.63 MMboe (-30.92 MMbbl of crude oil, condensate and NGL and -26.47 Bcf of natural 
gas) due to the conversion of proved undeveloped reserves to proved developed reserves as a result of: (a) 
the drilling success in Vaca Muerta formation of 21 wells (five pads) in Bajada del Palo Oeste (-24.99 
MMbbl of crude oil, condensate and NGL and -23.36 Bcf of natural gas); (b) the drilling success of five 
wells (two pads) in Bajada del Palo Este (-5.61 MMbbl of crude oil, condensate and NGL and -2.82 Bcf 
of natural gas); and (c) the recategorizations in Bajada del Palo Oeste (i.e., Farm-out Agreements) (-0.32 
MMbbl of crude oil, condensate and NGL and -0.29 Bcf of natural gas); and 
 
• 
A decrease of 0.69 MMboe (-0.28 MMbbl of crude oil, condensate and NGL and -2.32 Bcf of natural gas) 
due to revisions to previous estimates related to: (a) changes in the development plan in Bajada del Palo 
Este conventional (-0.17 MMbbl of crude oil, condensate and NGL and -0.44 Bcf of natural gas); (b) an 
adjustment in Aguada Federal due to the latest well results (-0.82 Bcf of natural gas); and (c) combined 
effects in other blocks (-0.11 MMbbl of crude oil, condensate and NGL and -1.06 Bcf of natural gas); 
Mexico: 
• 
A decrease of 0.58 MMboe (-0.22 MMbbl of crude oil, condensate and NGL and -2.05 Bcf of natural gas) 
related to the revision to previous estimates due to the change in proved undeveloped reserves plan due to 
the latest results in the drilling campaign. 
 
During 2024, we invested US$442.1 million (corresponding to the drilling, completion and tie-in activities 
and tie-in facilities of 26 gross or net new shale wells) to convert proved undeveloped reserves to proved developed 
reserves. During 2023, we invested US$200.9 million (corresponding to the drilling, completion and tie-in activities 
of 16 gross new shale wells or 14 net new shale wells) to convert proved undeveloped reserves to proved developed 
reserves.  

 
64 
 
We plan to put 100% of our reported 2024 year-end proved undeveloped reserves into production through 
activities to be implemented within five years of initial disclosure. 
As a result of the Conventional Assets Transaction, we transferred the operations of six conventional assets 
in Argentina, effective March 1, 2023. See “—Transaction to Increase Focus on Shale Oil Operations in Vaca 
Muerta.” 
Reserves Estimation Process—Internal Controls  
We maintain an internal staff of petroleum engineers and geoscience professionals who work closely with 
our independent reserves engineering consultants to ensure the integrity, accuracy and timeliness of data used by our 
independent reserves engineering consultants in their estimation process and who have knowledge of the specific 
properties under evaluation. Our Chief Operations Officer, Matías Weissel, is primarily responsible for overseeing the 
preparation of our reserves estimates and for the internal control over our reserves estimation. He has more than 20 
years of experience in E&P and oilfield services. See “Item 6—Directors, Senior Management and Employees—
Executive Team.” 
In order to ensure the quality and consistency of our reserves estimates and reserves disclosures, we maintain 
and comply with a reserves process that satisfies the following key control objectives:  
• 
estimates are prepared using generally accepted practices and methodologies;  
• 
estimates are prepared objectively and free of bias;  
• 
estimates and changes therein are prepared on a timely basis;  
• 
estimates and changes therein are properly supported and approved; and  
• 
estimates and related disclosures are prepared in accordance with regulatory requirements.  
Throughout each fiscal year, our technical team meets with Independent Qualified Reserves Engineers, who 
are provided with full access to complete and accurate information pertaining to the properties to be evaluated and all 
applicable personnel. This independent assessment of the internally-generated reserves estimates is beneficial in 
ensuring that interpretations and judgments are reasonable and that the estimates are free of preparer and management 
bias.  
Recognizing that reserves estimates are based on interpretations and judgments, there might be differences 
between the proved reserves estimates prepared by us and those prepared by an Independent Qualified Reserves 
Engineer. Although such differences were discussed in the technical meetings, the reports include figures estimated 
by our Independent Qualified Reserves Engineer. Once the process is finished, the Independent Qualified Reserves 
Engineer sends a preliminary copy of the reserves report to members of our senior management, who act as a 
Reserves Review Committee. Our Chief Operations Officer, Chief Technology Officer, Chief Executive Officer, 
Chief Financial Officer and Investor Relation and Strategic Planning Officer are part of this committee.  
Independent Reserves Engineer Consultants 
The 2024 reserves estimates of the assets we own in Argentina and Mexico were certified by D&M, a global 
oil and gas consultancy that has been offering technical, commercial, and strategic advice to the oil and gas industry 
since 1936. Vista asked D&M to prepare the 2024 Reserves Report which was issued on January 27, 2025, covering 
reserves as of December 31, 2024, of the assets we own in Argentina and Mexico. For the year ended December 31, 
2024, the technical person within the third-party engineering firm overseeing the preparation of the reserves estimates 
presented in our filing for Argentina and Mexico was Mr. Federico Dordoni. For disclosure describing the 
qualifications of D&M’s technical person primarily responsible for overseeing our reserves evaluation, see Exhibit 
99.1 to this annual report.  
Technology Used in Reserves Estimation  
According to SEC guidelines, proved reserves are those quantities of oil and gas which, by analysis of 
geoscience and engineering data, can be estimated with “reasonable certainty” to be economically producible—from 

 
65 
 
a given date forward, from known reservoirs, and under existing economic conditions, operating methods and 
government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence 
indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for 
the estimation  
The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain 
that it will commence the project within five years. The term “reasonable certainty” implies a high degree of 
confidence that the quantities of oil and/or natural gas actually recovered will equal or exceed the estimate. 
Reasonable certainty can be established using techniques that have been proved effective by actual production from 
projects in the same reservoir or an analogous reservoir or by other evidence using reliable technology that establishes 
reasonable certainty. Reliable technology is a grouping of one or more technologies (including computational 
methods) that have been field tested and have been demonstrated to provide reasonably certain results with 
consistency and repeatability in the formation being evaluated or in an analogous formation.  
There are various generally accepted methodologies for estimating reserves including volumetric, decline 
analysis, material balance, simulation models and analogies. Estimates may be prepared using any deterministic 
methods. The particular method chosen should be based on the evaluator’s professional judgment as being the most 
appropriate, given the geological nature of the property, the extent of its operating history and the quality of available 
information. It may be appropriate to employ several methods in reaching an estimate for the property.  
Estimates must be prepared using all available information (open and cased hole logs, core analyses, 
geologic maps, seismic interpretation, production/injection data and pressure test analysis). Supporting data, such as 
working interest, royalties and operating costs, must be maintained and updated when such information changes 
materially.  
Our estimated proved reserves as of December 31, 2024 are based on estimates generated through the 
integration of available and appropriate data, utilizing well-established technologies that have been demonstrated in 
the field to yield repeatable and consistent results. Data used in these integrated assessments include information 
obtained directly from the subsurface via wellbore, such as well logs, reservoir core samples, fluid samples, static and 
dynamic pressure information, production test data, and surveillance and performance information. The data utilized 
also include subsurface information obtained through indirect measurements, including high quality 2-D and 3-D 
seismic data, calibrated with available well controls. Where applicable, geological outcrop information was also 
utilized. The tools used to interpret and integrate all this data included both proprietary and commercial software for 
reservoir modeling, simulation and data analysis. In some circumstances, where appropriate analog reservoir models 
are available, reservoir parameters from these analog models were used to increase the reliability of our reserves 
estimates.  
Acreage  
As of December 31, 2024, our total developed and undeveloped operated acreage in Argentina and Mexico, 
both gross and net, was as follows. The table includes the total acreage by us and our subsidiaries, joint operations

Drilling Activities 
As of the date of this annual report, our drilling activities are concentrated in Argentina. 
During the year ended December 31, 2024, as operators, we drilled 50 net wells in Argentina and zero net 
wells in Mexico and performed zero workovers. All of these drilled and completed net wells targeted oil-weighted 
formations and no net wells targeted gas formations.  
During the year ended December 31, 2023, as operators, we drilled 32 net wells in Argentina and six net 
wells in Mexico and performed one workovers. All of these drilled and completed net wells targeted oil-weighted 
formations and no net wells targeted gas formations.  
During the year ended December 31, 2022, as operators, we drilled 26 net wells and performed five 
workovers. Among the drilled and completed wells, 24 new net wells targeted oil-weighted formations, whereas two 
net wells targeted gas formations.

We hold a non-operated working interest of 1.5% in Acambuco. During the year ended December 31, 2024, we 
did not participate in any drilling activities in Acambuco. As a result of the Conventional Assets Transaction, we 
transferred the operations of six conventional assets in Argentina, effective March 1, 2023. During the year ended 
December 31, 2024, two gross wells were drilled in these assets. See “—Transaction to Increase Focus on Shale Oil 
Operations in Vaca Muerta.” 
 
One Team Contracts  
We use a contracting approach (“One Team Contracts”) which aims to align the economic interests of Vista 
and key contractors through performance-based remunerations. Operationally, we aim to integrate our operating team 
with our service providers’ team by sharing common objectives and goals and by using same key performance 
indicators, which provide economic incentives to the personnel of all companies working under the One Team 
Contracts scope. The One Team Contracts program covers the most important suppliers in our shale oil development: 
(i) One Team Drilling, which involves SLB and Nabors drilling, and (ii) One Team Completion, which involves SLB 
and Brent Energía y Servicios. 
Transportation and Treatment 
In our operated blocks in Argentina, we treat and transport our oil, gas and water production in existing 
transportation treatment facilities that have sufficient capacity to process and deliver our current hydrocarbon 
production. As of the date of this annual report, these existing treatment facilities are comprised of several oil and gas 
pipelines, nine tank batteries distributed throughout the blocks, two oil treatment plant, two water treatment plants and 
six gas compression stations. 
All multiphase production from Bajada del Palo Oeste, Bajada del Palo Este, Aguada Federal and Coirón 
Amargo Norte is gathered at primary separation batteries. The oil is then transported via pipeline to the Entre Lomas 
treatment plant, which has a processing capacity of 75,000 barrels per day, where it is treated to meet sales 
specifications. Oil for sale is subsequently transported from the Entre Lomas processing plant into the Oldelval 
pipeline system. In 2024, a second oil processing plant, with a capacity of 15,000 barrels per day, was commissioned 
at Bajada del Palo Oeste. Oil for sale from this facility is pumped into the Vaca Muerta Norte pipeline, which 
connects to Chile through the Trasandino pipeline.  
Water is treated at, and pumped to disposal wells from, the Bajada del Palo water treatment plant (PIAS Borde 
Montuoso; 25,000 bbl/d capacity) and the Entre Lomas water treatment plant (80,000 bbl/d capacity). Gas production 

 
69 
 
from Bajada del Palo Oeste and shale production of Bajada del Palo Este is compressed and dehydrated in four 
compressor stations.  
Gas for sale is injected into TGS Vaca Muerta system at Tratayen for further treatment, and finally injected 
into the TGS or TGN systems. Part of the gas production from Aguada Federal is boosted and sent to a low-pressure 
gathering system in a neighboring block. Gas is then treated and compressed into TGS sales pipelines.  
During 2024, new capacity for high pressure gas evacuation was installed, allowing the integration of Aguada 
Federal with the Bajada del Palo Oeste gas evacuation system. Gas from Coirón Amargo Norte is dehydrated and 
injected into the TGN Centro Oeste system. Conventional Gas from Bajada del Palo Este production is injected into 
Entre Lomas gas treatment plant (45 MMscf/d capacity), which injects spec gas into the TGS system.  
Águila Mora production is separated in the block. Gas is compressed, dehydrated and injected into a gas 
pipeline on a neighboring block, which injects into the TGS Vaca Muerta system. Oil and water produced in Águila 
Mora are trucked to a tank battery at Bajada del Palo Oeste, where fluids are incorporated into the Bajada del Palo 
Oeste systems described above. 
As a result of the Conventional Assets Transaction with Aconcagua, the gas complex in Entre Lomas Central 
Production Facility is now operated by Aconcagua. Vista Argentina and Aconcagua have signed two agreements, 
whereby (i) Aconcagua will treat and dispatch the natural gas corresponding to Vista Argentina injected at the Entre 
Lomas Central Production Facility, and (ii) Vista Argentina will treat and transport the crude oil and water 
corresponding to Aconcagua arising from Agua Amarga and Entre Lomas. 
Midstream 
Once treated, we use the oil pipeline system and oil tankers to transport oil to our customers. Oil is 
customarily sold through contracts whereby producers are responsible for transporting produced oil from the field to 
refinery gate or a port for shipping, with all costs and risks associated with transportation borne by the producer. Gas, 
however, is sold at the point of injection of the gas pipeline system near the oil field and, therefore, the customer bears 
all transportation costs and risks associated therewith.  
Oil and gas transportation in Argentina partly operates in an “open access” non-discriminatory environment 
under which producers have equal and open access to the transportation infrastructure. Under certain open access 
rules, transportation capacity can be secured by oil producers if oil production levels are sustained month over month. 
As of the date of this annual report, we have secured open access capacity in the Oldelval pipeline. In addition, we 
maintain storage capacity at the oil Terminal located in Puerto Rosales, near Bahía Blanca from which oil is delivered 
to our end customers. 
As of the date of this report, our existing open access capacity in Oldelval was 43 Mbbl/d (includes 9 Mbbl/d 
corresponding to friction-reducing agents in use as of May 2024). In addition, we hold 12 Mbbl/d of pipeline capacity 
in the Vaca Muerta Norte and Trasandino pipelines to access Chile. We are also awarded a crude oil transportation 
capacity of 31.5 Mbbl/d in the project to expand the Oldelval pipeline from Allen to Puerto Rosales, which became 
fully online during March 2025. As a result, as of the date of this report, we held approximately 87 Mbbl/d of oil 
pipeline transportation capacity. We also held approximately 37 Mbbl/d of oil transportation capacity through 
trucking.

(1) Based on contracts signed by Vista and data provided by project operators. Actual delivery dates and capacity might change subject to 
execution. Oldelval pipeline includes 9 Mbbl/d corresponding to friction-reducing agents in use as of May 2024. 
 
Additionally, we have acquired capacity in two expansion projects, as shown below: 
• 
On January 27, 2023, the Company, through its subsidiary Vista Argentina, was awarded storage 
and dispatch capacities of 225 Mbbl and 37.4 Mbbl/d, respectively, in the project executed by 
Oiltanking Ebytem S.A. to expand the Puerto Rosales marine terminal and pumping station by 
1,887 Mbbl and 315 Mbbl/d, respectively. Accordingly, the Company committed to making an 
upfront payment of US$28.4 million between 2023 and 2025, which will be recovered from the 
monthly service fee. The expansion project is expected to commence operations in the second 
quarter of 2025. 
• 
On December 16, 2024, the Company, through its subsidiary Vista Argentina, entered into an 
agreement with YPF S.A., Pampa Energía S.A., and Pan American Sur S.A. for the construction of 
the VMOS Project. Between December 20, 2024 and March 7, 2025, Pluspetrol S.A., Chevron 
(through two subsidiaries), Shell (through two subsidiaries) and Gas y Petróleo del Neuquén S.A. 
also confirmed their participation. Under this agreement, the Company was allocated firm 
transportation, storage, and dispatch capacity of 50 Mbbl/d in the VMOS Project. The project is 
expected to have a total capacity of 550 Mbbl/d in its first stage, which is anticipated to be fully 
operational in the second half of 2027. See “—Vaca Muerta Sur Project.” 
 
For more detail on the midstream infrastructure network in Argentina, see “—Industry and Regulatory 
Overview—Oil and Gas Regulatory Framework in Argentina—Oil Midstream and Downstream.” 
Delivery Commitments 
We are committed to providing fixed and determinable quantities of crude oil, natural gas and NGL in the 
near future under a variety of contractual arrangements, some of them under firm arrangements and others on a spot 
basis. 
As of December 31, 2024, 21% of our oil production was subject to monthly delivery commitments in the 
domestic market and 11% of our oil production was subject to delivery commitments in the international markets. 
According to our estimates, as of December 31, 2024, our contractual delivery commitments, could be met with our 
own production. 

 
71 
 
For natural gas, in April 2024 we signed annual commitments for the period May 2024 to April 2025, which 
added to the commitments already assumed with the Plan GasAr until 2028 representing approximately 90% of our 
marketable total production, with seasonal pricing arrangements. The remainder is sold to the spot market. The annual 
commitments for the period May 2025 to April 2026 are expected to be signed by the end of April 2025. 
For LPG, our Propane production was not subject to delivery commitments during 2024. Regarding Butane 
we deliver under a National Decree approximately 75% of our annual production to guarantee local LPG cylinders 
demand for residential consumers.  
Customers and Marketing  
Oil Markets  
In Argentina, our crude oil production was sold both to domestic refineries and exported during 2024, 2023 
and 2022. During 2024, we exported 49% of our oil sales volumes, compared to 52% in 2023 and 44% in 2022. 
During 2024, 68% of our oil sales volumes were sold at export parity, combining sales to international buyers and 
domestic buyers paying export-parity prices, compared to 57% during 2023. In the past three years, our main 
domestic customers were Raizen and Trafigura. Approximately 99% of our oil is produced in the Neuquina Basin and 
is referred to as Medanito crude oil, a light sweet crude oil generally demanded by Argentine refiners in the domestic 
market, as well as by international refiners. Production from our Neuquina Basin properties is transported to Puerto 
Rosales, a major industrial port in the southern region of the Province of Buenos Aires through the Oldelval pipeline 
system, then goes to either the domestic refining market, which consists of seven active refiners with a total installed 
capacity of 620 Mbbl/d, or to international customers through maritime transportation. Additionally, as of May 2023, 
we initiated oil exports to Chile through the Trasandino oil pipeline. Even though we prioritize long-term 
relationships with domestic customers, we have developed relationships with international customers in order to 
establish a diversified portfolio for our expected production increase in the upcoming years. 
In Mexico, 100% of our crude oil production is sold to Pemex. See “—Industry and Regulatory Overview—
Mexico’s Oil and Gas Industry Overview.” 
Natural Gas Markets and NGL  
In Argentina, we have established a diversified portfolio of customers for natural gas. Our primary customers 
in 2024 were industrial customers, representing 48% of our total natural gas sales volumes for such period. In 2023, 
our primary customers were also industrial customers, representing 45% of our total natural gas sales volumes for 
such period. Argentina has a highly developed natural gas market and a sophisticated infrastructure in place to deliver 
natural gas to cross-border export markets through several gas pipelines or to industrial and residential customers in 
the domestic market. However, natural gas markets in Argentina are regulated by the Argentine government. Even 
though the Argentine government sets the price at which natural gas producers sell volumes to residential customers, 
volumes that are sold to industrial and other customers are not regulated and pricing varies with seasonal factors and 
industry category. We generally sell our natural gas to Argentine customers pursuant to short-term contracts and in 
the spot market. The Neuquina Basin is served by a substantial gas pipeline network that delivers gas to the Buenos 
Aires metropolitan and surrounding areas, and the industrial regions of Bahía Blanca and Rosario. Natural gas 
produced in our Neuquina Basin properties is readily marketed due to accessibility to such infrastructure. Our 
properties are well situated in the Basin with four major pipelines in close proximity. In Mexico, all the natural gas 
production is sold to Pemex.  
In relation to the Plan GasAr, on December 22, 2022, through Resolution No. 860/2022 of the SdE, Vista 
Argentina was awarded a base volume of 0.86 MMcm/d at an annual average price of US$3.29/MMBtu, applicable 
until December 31, 2024. On April 19, 2023, through Resolution No. 265/2023 of the SdE, the base volume awarded 
to Vista Argentina was increased to 1.14 MMcm/d, maintaining the annual average price of US$3.29/MMBtu, 
applicable for a four-year period as from January 1, 2025. See “—Industry and Regulatory Overview—Oil and Gas 
Regulatory Framework in Argentina—Plan GasAr 2020-2024.” 
With regards to our NGL production, we comply with domestic commitments set by the Argentine 
government with the objective of ensuring the supply for propane and bottled butane for residential uses. Our 
remaining NGL production is marketed within the Neuquina Basin.  

 
72 
 
Competition  
The oil and gas industry is competitive, and we may encounter strong competition from other independent 
operators and from major oil companies in acquiring and developing concessions or oil agreements. In Argentina, we 
compete for resources with state-controlled YPF, as well as with privately-owned companies such as Pan American, 
Pluspetrol, Tecpetrol, Chevron, Total, Compañía General de Combustibles, among others. In Mexico, we compete for 
resources with Pemex, the state-owned company, and local and international oil companies.  
Intellectual Property  
Our intellectual property is an essential element of our business, and our success depends, at least in part, on 
our ability to protect our core technology and intellectual property. To accomplish this, we rely on a combination of 
patent, trade secret, trademark and other intellectual property laws, confidentiality agreements and license agreements 
to establish and protect our intellectual property rights. As of December 31, 2024, we had all our trademarks duly 
registered with the regulatory authorities, noting as well that patent applications is not part of our usual business. 
Information Technology 
We rely on our information technology systems and automated machinery to efficiently manage our 
production processes and operate our business. Vista is a cloud-native company that has developed a strategy over the 
years to operate its technology stack in a multicloud environment. We use various public cloud providers (e.g., AWS, 
GCP, and Azure) for digital products and on-premises systems for SCADA and DCS operations. Our partners of 
choice for high-availability servers and storage include Dell, IBM, and NetApp; for networking and firewalls, we rely 
on Cisco; and for administrative processes and internal controls, we use SAP and satellite solutions, which 
standardize our operations across the organization. 
As with other organizations, our information technology systems are susceptible to damage or interruptions 
caused by cyber-attacks and security breaches. We adhere to the Cybersecurity Framework developed by the U.S. 
Department of Commerce’s National Institute of Standards and Technology (“NIST”). We evaluate, in collaboration 
with a top-tier third-party consultant, our maturity level against this framework, monitor current cybersecurity trends, 
and review disclosure research. Our cybersecurity strategy is aligned with NIST’s six core functions, as defined in the 
February 2024 release (version 2.0), to identify cybersecurity gaps and requirements. In 2024, we achieved and 
maintained a NIST maturity level that exceeds our target of 3.5. 
We consolidate all information from the various applications and real-time databases, which come from our 
operational sensors, into multicloud Data Lakes. From there, we perform data integrations, develop products, and 
create AI solutions with a high-quality, data-driven approach focused on business value. The use of real-time acquired 
data to enable Near Real-Time decision-making is critical, which is why we have connected our field offices and 
facilities to the internet via a high-bandwidth fiber optic network (>200mbps) with sufficient redundancy to ensure 
+95% uptime, in line with our Cloud strategy. 
We depend on digital technology, including information systems to process financial and operational data, 
analyze seismic and drilling information, estimate oil and gas reserves, and utilize real-time systems to monitor and 
control production. Due to the critical nature of this infrastructure and the increased accessibility provided by internet 
connectivity, our systems are exposed to a heightened risk of cyber-attacks. See “Item 3—Key Information—Risk 
Factors—Detailed Risk Factors—Risks Related to Our Business and Industry—Our industry has become increasingly 
dependent on digital technologies to carry out daily operations and is subject to increasing cybersecurity threats “ 
and “Item 16K—Cybersecurity.”  
Environmental Policy 
In 2021, we announced our ambition to reduce GHG emissions through a multi-year decarbonization plan. 
This five-year plan prioritizes selected projects from our abatement cost curve based on their carbon abatement 
potential and cost efficiency. We forecast a reduction of more than 80% in our scope 1 and 2 GHG emissions 
intensity, from 39 kgCO2e/boe in 2020 to 7 kgCO2e/boe in 2026. In 2024, we recorded a scope 1 and 2 GHG 
emissions intensity of 8.8 kgCO2e/boe, representing a 44% reduction compared to 15.6 kgCO2e/boe in 2023. 
 

 
73 
 
Additionally, we are developing our own portfolio of nature-based solutions (“NBS”) projects to capture 
carbon in soil and forests.  In 2022, we established Aike, a Vista subsidiary dedicated to designing, managing, and 
executing carbon offset projects, staffed with leading local experts. Aike aims to generate carbon credits of the 
highest quality, meaning that their impact is measurable, additional, permanent and positive for local communities 
and biodiversity. We believe NBS represents the most actionable, proven, efficient, and scalable carbon removal 
alternative currently available. Aike is developing 13 NBS projects in Argentina, across seven Provinces (Salta, 
Formosa, Corrientes, Santa Fe, Cordoba, San Luis and Buenos Aires), including mixed afforestation and reforestation 
with native and exotic species, forest conservation, improved forest management, and regenerative agriculture and 
livestock projects.  
 
By developing a top-tier NBS portfolio, we expect to generate a volume of carbon credits by 2026 that, from 
that year on, will be equivalent or potentially higher than the annual carbon emissions from our operation. 
 
Emissions and carbon credits calculation methodology 
Vista’s GHG emissions inventory reports two of the most prevalent GHG emissions components in oil and 
gas operations: CH4 and CO2. In addition, the calculated emission totals include N2O as well. Although emissions of 
the other GHG emissions components may exist in the Company’s operation, their relative contribution to the total 
GHG emissions is considered immaterial. 
 
Emissions from CO2, N2O, and CH4 are calculated and converted into total CO2e emissions by multiplying 
the emissions of each constituent by its respective global warming potential. 
 
The GHG emissions inventory for Vista was developed following best practices and industry guidelines for 
quantifying, reporting, and managing GHG emissions. Specifically, the Company adheres to: (i) the IPIECA 
Petroleum Industry Guidelines for Reporting Greenhouse Gas Emissions (2011) and (ii) the American Petroleum 
Institute (“API”) Compendium of Greenhouse Gas Methodologies for the Oil and Natural Gas Industry (2009). The 
inventory calculations apply standardized methodologies provided in the API Compendium for Vista’s relevant 
emission sources, with emission factors derived from published references within the API Compendium. Where 
actual operational emission factors or parameters are available, these values are incorporated into the GHG emissions 
inventory to enhance accuracy and representativeness. 
 
Vista’s GHG emissions inventory is structured according to the Operational Control approach, meaning 
each asset owned and operated by the Company is reported at 100% of its emissions in Argentina. Vista’s operated 
assets in Argentina include the following concessions: Águila Mora, Aguada Federal, Bajada del Palo Oeste, Bajada 
del Palo Este, Coirón Amargo Norte, and the Entre Lomas treatment plant. Our emissions information excludes the 
emissions arising from concession areas that we do not operate in Argentina and from our operated asset in Mexico. 
The GHG emissions inventory is further categorized by emission sources within each area of this organizational 
structure. 
 
Vista’s GHG emission inventory tool is classified into scope 1 and 2 sources, as shown below: 
 
GHG Source Category 
GHG Emissions Sources 
Scope 1 Sources 
Stationary combustion 
Heaters (i.e., treaters and ovens) 
Gas turbine / centrifugal compressor drivers 
Internal combustion engines 
Mobile combustion 
Automobiles 
Light duty trucks 
Flares 
Flares 
Fugitives 
Onshore oil and gas production equipment component leaks (e.g., valves, connectors, open-ended lines, etc.) 
Venting 
Glycol dehydrators 
Natural gas-operated chemical injection pumps 

 
74 
 
Natural gas-operated pneumatic devices 
Storage tank flashing losses 
Tank blanketing using natural gas 
Maintenance and turnaround activities 
Other venting (i.e., blowdowns and emergency shutdowns) 
Scope 2 Sources 
Indirect energy 
Imported electricity 
Imported electricity by a third party 
 
It should be noted that the inventory excludes GHG emissions sources with insignificant potential for GHG 
emissions that are immaterial to the total emissions quantified (also referred to as de minimis sources). Examples of 
insignificant sources include fire-fighting equipment and laboratory equipment. 
 
For many GHG emission sources, there are multiple options for determining the emissions, often with 
different accuracies. In general, emissions from a particular source are derived by applying an emission factor (“EF”) 
for a specific type of source or event with the corresponding activity factor. EFs used in the calculation methods come 
from published sources, referenced in the API Compendium and derived from publications by the IPCC, the EIA, the 
Gas Research Institute, and the U.S. Environmental Protection Agency. 
 
Where possible, EFs are derived based on site-specific gas compositional data. In many instances for 
combustion sources, the CO2 EF represents the application of material balance principles and the assumption that 
100% of the carbon available in the fuel stream is oxidized to CO2. In addition, for flaring sources; a destruction 
efficiency of 98% is assumed to calculate the CH4 EF. 
 
After GHG emissions inventory tool is completed and results obtained for every calendar year, a third-party 
verification is carried out. GHG emission inventory results are only published once the verification is completed, and 
the calculations verified. 
 
Health and Safety Policy  
The implementation of additional safety procedures in our operations in consistency with our Health and 
Safety Policy, such as training, work permits, internal audits, drills, tailgate safety meetings, job safety analysis and 
risk evaluations, has led to a reduction in the number of workforce safety incidents.  
Our safety management system is applied following an Operating Management System (“OMS”) framework 
and covers all our employees and contractors working in our offices, fields and providing services. The OMS was 
designed based on recommended practices for the oil and gas industry and according to IOGP and IPIECA guidelines. 
In 2024, our TRIR was 0.59 (based on 6.7 million work hours during the period) as compared to a 0.18 
(based on 5.6 million work hours during the period) as of December 31, 2023, and 0.86 (based on 4.6 million work 
hours during the period) as of December 31, 2022. In 2024, a fatality occurred during a drilling operation conducted 
by Nabors for Vista. We had no fatalities due to workforce incidents involving Vista employees related to operations 
in the years ended December 31, 2023 and December 31, 2022.  
ESG Matters 
We aim to develop our business sustainably. We strive to protect the environment where we operate, with 
special focus on GHG emissions, water management, energy efficiency and waste management.  
Regarding emissions, our goal is to reduce our operating scope 1 and 2 GHG emissions intensity by more 
than 80%, reaching 7 kgCO₂e/boe in 2026, compared to 39 kgCO₂e/boe in 2020. Additionally, we are executing a 
portfolio of NBS projects through our subsidiary Aike in Argentina. By developing a top-tier NBS portfolio, we 
expect to generate a volume of carbon credits by 2026 that, from that year on, will be equivalent, or potentially 
higher, to the annual carbon emissions from our operations. 

 
75 
 
We believe our value resides in our oil producing assets, as much as in our teams and their commitment to 
operational excellence. In this respect, health and safety are the cornerstones to ensure our teams achieve best 
performance, and we have made it a Company priority to provide our people with the highest oil and gas industry 
standards when it comes to occupational health and safety, as set by IOGP and IPIECA.  
In addition, we seek to create a working environment where high performance, teamwork, innovation, agility 
and responsibility are values shared by all in our staff. We are firm believers in the value of developing an 
organizational culture that works in appreciation of each person, promoting diversity, equity and inclusion (DEI) at all 
levels. To support this, we implement various initiatives through our Vista Diversity, Equity & Inclusion program.  
We are also committed to the development of the communities in which we operate by fostering an inclusive 
business model and strengthening the sense of belonging through open dialogue, active collaboration, volunteering, 
and social engagement. 
Additionally, we seek to operate our business responsibly, ethically, and in alignment with the interests of 
our stakeholders. We are committed to effective and sustainable corporate governance, which we believe strengthens 
accountability, promotes the long-term interests of our stakeholders, and helps build public trust in our Company. As 
a public company, our business and corporate governance practices comply with the regulations set forth by the SEC 
of the United States applicable to foreign private issuers and the CNBV of Mexico rules, as well as with national 
regulations in the countries where we operate.  
During 2024, we made good progress across all ESG fronts. The main highlights are summarized below:

Disclosures 2021), GRI 3 (Material Topics 2021) and GRI 11 (Oil and Gas Sector 2021), and (ii) the Sustainability 
Accounting Standards Board for industry-specific ESG topics relevant to our financial performance and long-term 
value creation. For the fourth consecutive year, the 2024 Sustainability Report will include information aligned with 
the recommendations published by the TCFD. Additionally, we expect to report our contribution to the UN 
Sustainable Development Goals. Our ESG progress is aligned with the 10 universal principles of the UN Global 
Compact and will serve as our 2024 Communication on Progress Report under the UN Global Compact framework. 
The 2024 Sustainability Report will be published on our website. Information contained on, or accessible through, our 
website is not incorporated by reference in, and will not be considered part of, this annual report. 
VX Ventures 
  
VX Ventures AenP (“VX Ventures”) is Vista’s corporate venture capital fund, launched with an initial US$12.5 
million funding commitment (which yearly investments represent less than 1% of Vista’s capital expenditures), with 
the objective of developing new businesses that can thrive through the energy transition and support Vista becoming a 
lower carbon and lower cost company. During 2023, funding was increased by US$2.5 million reaching a total of 
US$15 million.  
  
During 2024, we continued to pursue entrepreneurial, agile and dynamic companies that may become key 
agents of change and leverage Vista’s technical and project management skills with an entrepreneurial drive to access 
new markets. 
  
Moreover, VX Ventures plays a role of exposing Vista to the optionality of new businesses that can potentially 
scale up and can also help us secure the access and retention of top talent. 
  
Each investment is funded through specific special purpose vehicles controlled by Vista, where certain relevant 
executives of the Company are given the option to co-invest through class B shares with no political rights to incentivize 
their engagement and align their interests with those of the invested project. 
  
As part of our VX Ventures portfolio, which as of December 31,2024 includes investments in 19 start-ups 
and early-stage companies, we have created and funded Aike NBS S.A.U. (“Aike”) to deliver top-quality carbon 
offsets through the development of NBS projects, including forestry and soil carbon capture projects. Aike aims to 
also provide services to third companies to help them to fulfill their NBS project development needs and achieve their 
carbon capture objectives which will in turn benefit Vista by providing larger scale for its NBS projects. Aike has 
already started providing services to us in connection with Vista´s own NBS portfolio.

Insurance 
We maintain insurance coverage of types and amounts that we believe to be customary and reasonable for 
companies of our size and with similar operations in the oil and gas industry. However, as is customary in the 
industry, we do not insure fully against all risks associated with our business, either because such insurance is not 
available, insurance coverage is subject to a cap or because premium costs are considered prohibitive.  
Currently, our insurance program includes, among other things, construction, fire, vehicle, technical, 
liability, director’s and officer’s liability and employer’s liability coverage. Our insurance includes various limits and 
deductibles or retentions, which must be met prior to or in conjunction with recovery. A loss not fully covered by 
insurance could have a materially adverse effect on our business, financial condition and results of operations.  
General Regulatory Matters 
We and our operations are subject to various stringent and complex international, federal, state and local 
environmental, health and safety laws and regulations in the countries in which we operate that govern matters 
including the emission and discharge of pollutants into the ground, air or water, the generation, storage, handling, use 
and transportation of regulated materials and human health and safety. These laws and regulations may, among other 
things:  
• 
require the acquisition of various permits or other authorizations or the preparation of environmental 
assessments, studies or plans (such as well closure plans) before seismic or drilling activity 
commences;  
• 
enjoin some or all of the operations of facilities deemed not in compliance with permits;  
• 
restrict the types, quantities and concentration of various substances that can be released into the 
environment in connection with oil and natural gas drilling, production and transportation activities;  
• 
require establishing and maintaining bonds, reserves or other commitments to plug and abandon wells; 
and  
• 
require remedial measures to mitigate or remediate pollution from our operations, which, if not 
undertaken, could subject us to substantial penalties.  
 
INDUSTRY AND REGULATORY OVERVIEW 
Argentina’s Oil and Gas Industry Overview 
Argentina has five producing oil and gas basins: Neuquina, Noroeste, Cuyana, Golfo San Jorge, and Austral. 
As of December 31, 2023, Argentina’s oil and gas reserves totaled 6,054 MMboe, as reported by the SdE. In 2024, 
Argentina’s oil production was 716.4 Mbbl/d, while its gas production reached 138.6 MMm³/d. Production from the 
Vaca Muerta formation, which is located within the Neuquina basin, accounted for 389.5 Mbbl/d of oil (54% of total 

 
78 
 
production) and 69.2 MMm³/d of gas (50% of total production), having recorded an oil production CAGR (compound 
annual growth rate) of 34% over the last five years.

Vaca Muerta Shale Formation 
The Vaca Muerta formation, located in the Neuquina Basin, is considered one of the most prominent shale 
plays globally, and has already become the largest commercial shale development outside North America. The 
development of the Vaca Muerta formation plays an important role in the Argentine economy, and therefore the 
federal and provincial governments have introduced changes to the regulatory framework for E&P of unconventional 
hydrocarbons to attract investments.  
Recent regulatory reforms, as well as significant reductions in well costs and improvements in production 
rates over the past decade, have attracted over 30 oil and gas companies to Vaca Muerta, both domestic and IOCs, 
including YPF, Vista, Shell, Pan American, Pluspetrol, Tecpetrol, Chevron, Total, Equinor, Petronas and Dow. Most 
of these companies, which hold acreage adjacent to our concessions, are already investing in their projects in full 
development mode, or in some cases are conducting project pilots.

Vaca Muerta acreage is estimated at more than 8.6 million acres, containing 16 Bnbbl of oil resources and 
308 Tcf of gas resources. Such resources are equivalent to approximately 100 years and 200 years of domestic oil and 
gas consumption, respectively. The top five oil operators are YPF, Vista, Shell, Pan American and Pluspetrol. Most 
concessions are within the 30,000 to 100,000 acres range, which is significantly larger than the average leasehold in 
the United States. The terms of concessions in Argentina are also competitive compared to those in the United States, 
with unconventional concessions of 35 years and flat royalties of 12%.  

 
80 
 
Over the past years, Vaca Muerta has increased significantly its well activity from 102 new wells in 2019 to 
401 new wells in 2024. The cumulative well count increased to 2,110 by year-end 2024. The quantity of active 
drilling rigs in the basin has also increased during the period, as shown below. Currently, approximately 30% of its 
surface area is under development.

Oil and gas production from Vaca Muerta was 847 Mboe/d during 2024, a 23% increase compared to 2023. 
Production from Vaca Muerta reached 894 Mboe/d in January 2025. The shale oil production during 2024 was mainly 
driven by Loma Campana, La Amarga Chica, Bajada del Palo Oeste (held and operated by Vista) and Bandurria Sur, 
which combined contributed with 245 Mbbl/d. Shale gas production was mainly driven by Fortín de Piedra, Aguada 
Pichana Este, Aguada Pichana Oeste and La Calera, which combined contributed with 256 Mboe/d.

Vaca Muerta production has played a significant role in offsetting the decline of other basins in Argentina 
and increasing total oil and gas production, positioning Argentina as a structural oil exporter of light crude oil since 
2022. As shown below, oil exports have increased from 68 Mbbl/d in 2019 to 187 Mbbl/d in 2024. Additionally, Vaca 
Muerta has allowed Argentina to reduce natural gas imports, both from neighboring Bolivia and Chile, and via LNG, 
which have decreased from 19.1 MMm³/d in 2019 to 7.8 MMm³/d in 2024. This trend has contributed significantly to 
improving Argentina’s balance of trade. According to the Argentine Ministry of Economy, Argentina’s energy trade 
balance was negative for US$4.4 billion in 2022 and reverted to a positive balance of US$5.7 billion in 2024.

Vaca Muerta is in a relatively early stage of its development compared to shale plays in the United States. 
The Permian Basin is a good analogue for Vaca Muerta, with similar geological characteristics and a long history of 
unconventional hydrocarbon development. However, Vaca Muerta has even more thickness than the Permian, with up 
to five different pay zones already tested in different blocks of the basin. As of December 31, 2024, operators have 
drilled around 2,100 wells in Vaca Muerta compared to around 50,000 in the Permian and more than 200,000 across 
all U.S. shale plays. It is possible that Vaca Muerta could have a growth trajectory similar to that of the Permian 
Basin or other U.S. shale plays in the coming years. The growing investment in Vaca Muerta is similar to the early 
stages of the Permian Basin’s remarkable growth since 2008, becoming one of the most prolific shale plays in the 
world.  
After an initial period of incorporating the technology required for unconventional development, progressing 
along the learning curve, and adopting best practices, the average well productivity per lateral foot in Vaca Muerta 
now exceeds its shale peers in the United States.

Oil Midstream and Downstream 
The Argentine crude oil pipeline network connects the producing basins with domestic refineries, which are 
located in the Province of Buenos Aires (i.e., La Plata, Bahía Blanca, Dock Sud, Campana), the Cuyo Basin 
(i.e., Luján de Cuyo), the Neuquina Basin (i.e., Plaza Huincul) and the Noroeste Basin (i.e., Refinor). These refineries 

 
83 
 
have a combined refining capacity of an estimated 620 Mbbl/d: La Plata has an approximate capacity of 200 Mbbl/d, 
Bahía Blanca 40 Mbbl/d, Dock Sud 110 Mbbl/d, Campana 95 Mbbl/d, Luján de Cuyo 125 Mbbl/d, Plaza Huincul 25 
Mbbl/d and Refinor 25 Mbbl/d. Argentina’s key crude pipeline is the Oleoductos del Valle S.A. (“Oldelval”) system, 
with an oil pipeline from Puesto Hernández and Allen in the Neuquina Basin to Puerto Rosales near Bahía Blanca, 
transporting approximately 65% of the production from the Neuquina Basin, with a capacity of approximately 
540,000 bbl/d. 
 
In Puerto Rosales, a marine export terminal is operated by Oiltanking Ebytem S.A. (“OTE”), a company 
owned by YPF (30%) and Oiltanking (70%). The OTE facilities have 18 tanks with a storage capacity of 3 MMbbl, of 
which 1,070 Mbbl are used to store Medanito-type crude oil. OTE also owns two buoys, Punta Ancla and Punta 
Cigueña, with capacities of 106,000 and 70,000 deadweight tonnage, respectively. These two buoys provide services 
mainly for loading and unloading Panamax vessels. 
 
In early 2023, the Trasandino pipeline connecting the Argentine system to Chile became operational after 
being shut for more than a decade. This enabled export flows from the Neuquina Basin to Chile starting in May 2023. 
This pipeline has a total capacity of 110,000 bbl/d. In November 2023, the Vaca Muerta Norte pipeline, with 157,000 
bbl/d of capacity, connecting Loma Campana to Puesto Hernández and the Trasandino pipeline, was commissioned. 
 
As of the date of this annual report, OTE is executing an expansion project to expand the Puerto Rosales 
marine terminal and pumping station by 1,887 Mbbl and 315 Mbbl/d, respectively. 
 
Additionally, in December 2024, the VMOS Project was announced, consisting of a new pipeline from Allen 
to Punta Colorada in the Province of Río Negro, storage facilities, and a new port in a deep-water location. The 
VMOS Project will have an estimated initial capacity of 550,000 bbl/d and is expected to be completed in the second 
half of 2027. 
The remaining oil production that is not refined and consumed in Argentina is exported. During 2024, 
Argentina exported 187 Mbbl/d, according to INDEC, of which an estimated of 150 Mbbl/d were exported from the 
Neuquina basin. The companies in the Neuquina basin exported 71 Mbbl/d in total to Chile during 2024 and the rest 
via the Atlantic (from Bahía Blanca).

Oil and Gas Regulatory Framework in Argentina 
The Argentine Hydrocarbons Law, as amended by Law No. 26,197, Law No. 27,007 and Law No. 27,742 
(Ley de Bases) is the main body of legislation for oil and gas E&P. The enforcement authority for the Argentine 
Hydrocarbons Law is the SdE. As a result of the amendment of the Argentine Hydrocarbons Law by means of the 
Law No. 26,197, each Province has its own enforcement authority. In particular, the Province of Neuquén has passed 
its own Argentine Hydrocarbons Law No. 2,453, among other laws and regulations on these activities. The 
transportation, distribution and marketing of gas are independently regulated by the Natural Gas Law, also amended 
by the Ley de Bases. 
Exploration and Production 
The E&P of oil and natural gas is carried out through exploration permits and exploitation concessions. 
Nevertheless, the Argentine Hydrocarbons Law permits surface reconnaissance of territories not covered by 
exploration permits or exploitation concessions, subject to prior authorization of the surface owner and the application 
authority. 
In the event that holders of an exploration permit discover commercially exploitable quantities of oil or gas, 
such holders are entitled to obtain an exclusive concession for the production and exploitation of the relevant reserves. 
The exploitation concession provides its holder the exclusive right to produce oil and gas from the area covered by the 
concession. An exploitation concession also entitles the holder to obtain a transportation authorization for transporting 
of the oil and gas produced. 
Holders of exploration permits and exploitation concessions are required to carry out all necessary works to 
find or extract hydrocarbons, using appropriate techniques, and to make the investments specified in their respective 
permits or concessions. In addition, holders must avoid damage to oil and gas fields and hydrocarbon waste, and 
undertake adequate measures to prevent accidents and damages. 
Both holders of exploration permits and holders of exploitation concessions must pay an annual fee based on 
the land area covered by the corresponding permit or concession (as provided in Section 7 of the Argentine 
Hydrocarbons Law). Holders of exploitation concessions are required to pay for such concessions, and to make 
certain royalty payments to the Argentine government. 
Exploration Permits and Exploitation Concessions 
The Argentine Hydrocarbons Law and its amendments regulate exploration and exploitation activities as 
follows: 
• 
Conventional Exploration Permits: the term for conventional exploration permits is divided into 
two periods of up to three years each, plus a discretionary extension of up to five years, granting a 
maximum validity of 11 years. The extension is optional for the permit holder who has fulfilled the 
investment and other obligations under their responsibility. For offshore operation permits, each 
period of the basic exploration term for conventional objectives may be increased by one year. 
 
• 
Unconventional Exploration Permits: the term for these permits is divided into two periods of up 
to four years each, plus a discretionary extension of up to five years, granting a maximum validity 
of 13 years. The extension is optional for the permit holder who has fulfilled the investment and 
other obligations under their responsibility. 
 
• 
Concessions: the term for the exploitation of conventional resources is 25 years, while for the 
exploitation of unconventional resources, a term of 35 years is established, including a pilot test of 
up to five years. In the case of offshore operations, concessions are granted for periods of up to 30 
years. Due to the modifications introduced by the Ley de Bases, the federal or provincial executive 
branch, as applicable, may determine in new concessions—at the time of defining the terms and 
conditions—other periods (of up to 10 years) additional to the aforementioned periods. These 

 
85 
 
periods cannot be set perpetually, unlike the previous regulation, which allowed the possibility of 
granting successive extensions for periods of 10 years. Concessions granted prior to the enactment 
of the Ley de Bases will continue to be governed by the terms established by the legal framework 
existing at the date of approval of the Ley de Bases.  
 
• 
Royalties: The Hydrocarbons Law established a 12% monthly royalty rate to be paid by the 
concessionaire for the production of liquid hydrocarbons extracted at the wellhead and for the 
volume of natural gas extracted and effectively utilized, with the granting authority having the 
ability to reduce such rate by up to 5% in exceptional cases, taking into account the productivity, 
conditions, and location of the wells, and to increase it by 3% upon the first extension. 
Concessions granted prior to the enactment of the Ley de Bases remain subject to this regime, 
requiring payment of the 12% royalty on the wellhead value of crude oil production and on the 
volume of natural gas sold, as well as an extraordinary royalty in certain extended concessions.  In 
contrast, the Ley de Bases replaced the fixed 12% rate with a percentage to be determined in the 
awarding process, applied to the production and effectively utilized liquid and gaseous 
hydrocarbons. It preserved the authority’s ability to reduce the rate by up to 5% in exceptional 
cases, while eliminating the 3% increase upon the first extension. The Ley de Bases also 
introduced the possibility of applying a reduced rate of up to 50% for projects involving: (i) 
Enhanced Oil Recovery (EOR) or Improved Oil Recovery (IOR) techniques, (ii) the exploitation of 
extra-heavy oils (requiring special treatment due to poor quality or high viscosity), and (iii) 
offshore exploitation. Concessions granted following the entry into force of the Ley de Bases are 
governed by the regime established therein. 
Exploration permits and exploitation concessions constitute an acquired right that cannot be extinguished 
without legal compensation. However, concessions or permits expire in the case of certain breaches detailed 
exhaustively in Article 80 of the Argentine Hydrocarbons Law. Concessionaires or permit holders can also partially 
or totally renounce the surface area of a permit or concession at any time. If an exploration permit is renounced, the 
permit holder will be obliged to pay the committed and unmet investment amounts (Articles 20 and 81 of the 
Argentine Hydrocarbons Law). 
Reserves and Resources Certification in Argentina  
The estimation of reserves and resources in Argentina is mainly governed by Resolution SdE No. 324/2006 
and SdE Resources Resolution No. 69-E/2016. These regulations require holders of exploration permits and 
exploitation concessions to file by March 31 of each year estimates of natural gas and oil reserves and resources 
existing as of December 31 of the previous year. Estimates must be certified by an external auditor and sent to the 
SdE. Information is required to be presented following the criteria approved by the SPE, the WPC (World Petroleum 
Council) and the AAPG (American Association of Petroleum Geologists), which are widely accepted internationally.  
The information regarding Vista’s proved reserves in this annual report has been prepared according to the 
definitions of Rule 4-10(a) of Regulation S-X or the SPE’s Petroleum Resources Management System, which differ 
from the relevant guidelines published by the SdE. 
Transportation 
The Ley de Bases introduced significant changes to the hydrocarbon transportation regime in Argentina, 
establishing a comprehensive framework for transport and processing authorizations managed by federal or provincial 
authorities. Existing transportation concessions will continue to operate under their original terms.  The Argentine 
Hydrocarbons Law grants producers the exclusive right to obtain transportation authorizations for oil, gas, and their 
by-products as specified in the law and related decrees.  
 
These authorizations permit the construction and operation of essential facilities for hydrocarbon transport, 
such as pipelines, storage, plants, and other necessary infrastructure, all subject to prevailing legislation and technical 
standards.   
 

 
86 
 
Holders of exploitation concessions are entitled to transportation authorizations. If the construction of 
permanent works exceeds the concession limits, they must obtain additional authorizations. If the works remain 
within the concession limits, the authorization is optional and granted under the same conditions as the exploitation 
concession. 
 
The duration of transportation authorizations aligns with the terms of the associated exploitation concessions. 
Upon expiration, the facilities revert to state ownership. Extensions of 10 years can be requested if obligations are met 
and hydrocarbons are being transported at the time of the request. Transport and processing authorizations do not 
grant exclusive rights to the holders. 
 
Authorized transporters must carry third-party hydrocarbons without discrimination, provided there is 
available capacity and no technical impediments. Unused transportation capacity must be made available to third 
parties, subject to the needs of the authorized transporter.  
 
Federal or provincial authorities will establish rules for coordinating transportation systems. Tariffs for 
hydrocarbon transportation and related services are regulated, with maximum amounts set by Resolution SdE No. 
5/04, as amended. These changes aim to streamline the hydrocarbon transportation and processing framework, 
ensuring fair access and efficient operation within the sector. 
 
 
Argentine Registry of Hydrocarbon Exploration and Exploitation Companies  
To be holders of exploration permits or exploitation concessions, irrespective of the Province where the 
activities are developed, companies must be registered with the Argentine Registry of Hydrocarbon Exploration and 
Exploitation Companies maintained by the SdE. Such holders and concessionaires must have adequate financial 
resources, pursuant to Disposition No. 335/2019 issued by the Sub-Secretariat of Hydrocarbons, and technical 
capabilities to perform the operations involved in the rights bestowed upon them. Further, such holders shall assume 
exclusive responsibility for liabilities associated with E&P activities. Registration with the Registry is also a 
requirement to be able to be an operator of permits and concessions and has to be annually renewed and can be 
revoked if technical capacity cannot be proved. Holders of permits and concessions shall establish legal domicile 
within Argentina.  
In all cases, the company or association of companies holding the permit or concession must maintain such 
net equity throughout the term of the permit or concession. These equity requirements may be satisfied by means of 
financial or other guarantees.  
Crude Oil Market Regulation 
The Argentine Hydrocarbons Law empowers the Argentine Executive Branch to set the national policy with 
respect to the exploitation, processing, transportation, storage, industrialization and commercialization of 
hydrocarbons. 
The Ley de Bases introduced amendments to Law No. 26,741 and the Argentine Hydrocarbons Law, to allow 
concessionaires, refineries, and/or hydrocarbon marketers to freely export hydrocarbons and/or their derivatives 
without needing to meet domestic demand. Additionally, it stipulates that the Argentine government may not 
intervene in setting commercialization prices in the domestic market at any stage of production. 
Until 2024, exports of crude oil and oil by-products in Argentina required prior registration in the Argentine 
Registry of Export Operations Agreements and authorization by the SdE. The Ley de Bases modified the Argentine 
Hydrocarbons Law, establishing that, although prior registration in the Argentine Registry of Export Operations 
Agreements is required, producers of crude oil and oil by-products may freely export hydrocarbons and/or their 
derivatives, absent objection by the SdE, no longer being needed it express authorization. The effective exercise of 
this right is subject to regulations issued by the Argentine Executive Branch, which must, among other aspects, take 
into account: (i) the standard requirements applicable to access to technically proven resources; and (ii) that any 
objection by the SdE may only (a) be raised within 30 days from the date on which the SdE becomes aware of the 

 
87 
 
export, and (b) must be based on technical or economic grounds related to the security of supply. Once said term has 
elapsed, the SdE may not raise any objection whatsoever, see “—Ley de Bases.” 
Gas Market Regulation 
As mentioned in previous sections, gas E&P activities are regulated by the Argentine Hydrocarbons Law, 
whereas natural gas transportation and distribution are regulated by means of the Natural Gas Law.  
In order to foster the production of natural gas, the Argentine government adopted different stimulus 
programs over the past years, such as the Plan GasAr implemented by means of Decree No. 892/2020 (amended by 
Decree No. 730/2022).  
Plan GasAr 2020-2024 
By means of Decree No. 892/2020, (amended by Decree No. 730/2022), the Argentine government 
implemented the Argentine Plan for the Promotion of Natural Gas Production – Supply and Demand Scheme 2020-
2024 (Plan de Promoción de la Producción de Gas Natural Argentino – Esquema de Oferta y Demanda 2020-2024).  
The Plan GasAr established the framework for the implementation of direct contracts (initially lasting four 
years, with the possibility of extension by the SdE for additional one-year periods) between gas producers, on the one 
hand, and gas distributors and/or sub-distributors (to meet priority demand) and CAMMESA (to meet the demand of 
thermal power plants), on the other. These contracts were awarded, and the price of gas at the point of entry into the 
transportation system (“PIST” for its acronym in Spanish) was determined through a tender procedure carried out by 
the SdE. The Argentine government may make monthly payments corresponding to a portion of the price of natural 
gas in the PIST to provide indirect subsidies to end users. 
On November 4, 2022, Decree No. 730/2022 was published in the Argentine Official Gazette, extending the 
Plan GasAr until the year 2028.The Plan GasAr is based on (i) voluntary participation by producers, public 
distribution service providers, and sub-distributors (making direct acquisitions from producers) and CAMMESA; (ii) 
a competitive scheme where the SdE calls for the signing of direct contracts between producers on one side, and 
priority demand (distribution licensees and/or sub-distributors) as well as the demand from thermal power plants 
(with CAMMESA) on the other; (iii) a framework of free market competition regarding the price of gas in the PIST, 
subject to the conditions set by the Argentine government.  
 
Ley de Bases 
On July 8, 2024, the Ley de Bases was published in the Argentine Official Gazette, introducing amendments 
to the Natural Gas Law and the Argentine Hydrocarbons Law. 
The main amendments to the Argentine Hydrocarbons Law include: 
• 
Expanding the self-sufficiency paradigm of the Argentine Hydrocarbons Law to incorporate the 
maximization of economic profits to encourage new investments; 
 
• 
Eliminating restrictions on hydrocarbon exports and establishing the freedom to market and export 
hydrocarbons and their derivatives; 
 
• 
Prohibiting the Argentine government from intervening in the pricing of oil, gas, and refined 
products in the domestic market; 
 
• 
Including hydrocarbon processing and storage activities within the regulatory framework; 
 
• 
Allowing the conversion of concessions from conventional to unconventional exploitation until 
December 31, 2028; 
 

 
88 
 
• 
Defining specific requirements for bidding on new areas and eliminating the possibility of 
extending exploitation concessions for new concessions; 
 
• 
Modifying the fees payable by concession and permit holders; 
 
• 
Revising the royalty regime, except for concessions already awarded; 
 
• 
Replacing transportation concessions with a system of transportation and storage authorizations, as 
well as hydrocarbon processing authorizations; and 
 
• 
Allowing foreign companies to participate in public bids for permits and concessions.  
 
The main amendments to the Natural Gas Law include the following: 
• 
Eliminating the requirement to obtain prior authorization for natural gas imports; 
• 
Removing the limitation that previously required the domestic market supply to remain unaffected; 
• 
Establishing a special framework for LNG, guaranteeing firm export conditions that, once 
authorized, cannot be modified; 
• 
Extending the duration of licenses for natural gas transportation and distribution services from 10 to 
20 years; and  
• 
Creating the Ente Nacional Regulador del Gas y la Electricidad to replace ENRE and ENARGAS, 
assuming their functions. 
 
On November 28, 2024, Decree No. 1057/2024 was published in the Argentine Official Gazette, regulating 
various aspects of the Ley de Bases related to the reform of the Argentine Hydrocarbons Law and the Natural Gas 
Law through three annexes.  
 
The key provisions include: 
 
• 
Reinforcing free market principles, including unrestricted exportation, supply security, and aligning 
domestic prices with international standards. The decree prioritizes resource efficiency, long-term 
contracts, and global trade integration. Applicants for permits and concessions must be domiciled in 
Argentina and meet financial solvency, net worth, and technical capacity requirements; 
 
• 
Ensuring free exportation upon compliance with specified conditions. Exporters must submit 
detailed technical and commercial information. Any objections must be resolved within 30 business 
days, and in the absence of objections, a free exportation certificate is issued; 
 
• 
Providing details regarding the conversion of concession areas, allowing unconventional 
exploitation without subdivision; 
 
• 
Establishing open-access requirements for unused transport capacity, with certain exceptions. 
Transport authorizations do not require public bidding and are not classified as public services; 
 
• 
Allowing entities involved in hydrocarbons to participate in the LNG market, subject to regulatory 
requirements. The export process includes a resource availability declaration, a technical and 
economic solvency assessment, and a project consistency evaluation. Any objections must be 
resolved within 120 business days. A free exportation authorization, valid for 30 years, is issued 
upon approval; 
 
• 
Requiring LNG exporters to periodically verify resource availability and report significant changes. 
Authorizations may be revoked for non-compliance. Rights may be transferred with prior approval; 

 
89 
 
 
• 
Extending the renewal period for transport and distribution concessions from 10 to 20 years. 
Applications must be submitted 54 months before expiration; and  
 
• 
Mandating the SdE to collaborate with the Provinces and the City of Buenos Aires to establish 
uniform environmental legislation, covering licensing, well abandonment, and environmental 
liabilities, to ensure responsible and sustainable management within the hydrocarbons sector.  
Special Frameworks to Access to the Foreign Exchange Market

Income From The Foreign Exchange Market.” 
 
Sustainability 
Argentina has regulation regarding the protection of the environmental on a federal, provincial and 
municipal level, as well as in the Argentine Constitution.  
 
For instance, Argentina applies the “polluter pays” principle and requires a mandatory approval of an 
environmental impact assessment for conducting risky activities. Moreover, legislation guarantees the right to access 
to environmental information, public participation in the environmental decision-making process, and access to 
justice in environmental matters. Environmental insurance is required, and reporting duties are also established. 
Argentina has approved several human rights international treaties and, in particular, related to the environment.  
 
A procurement regime applicable to the Argentine government has been established by means of Decrees 
No. 1023/01 and No. 1030/16, which requires to consider sustainability in the decision-making process in the 
acquisition of services and goods by the public administration. Furthermore, Decree No. 31/2023 declares a national 
public priority policy for the sustainable management of resources used by national public agencies. Those practices 
provide for the efficient management of the following: electricity; water; natural gas; waste; public procurement; 
accessibility; sustainable mobility; and green areas and spaces.  
 
Likewise, by means of its Resolution No. 635/2022 (as amended by its Resolution No. 668/2022) the 
Argentine Ministry of Transportation approved the National Sustainable Transportation Plan. Its main objective is to 
promote energy transition and efficiency in transportation to achieve sustainable mobility. Such plan contains a set of 
strategies and policies to be implemented by 2030, promoting the reduction of GHG emissions. Other sustainability 
regulations have been passed. Its impact on the oil and gas industry has yet to be assessed. 
 
In addition, as a member of the UN Framework Convention on Climate Change (“UNFCCC”) and a Party 
to the Paris Agreement, Argentina has committed to submit its Nationally Determined Contributions (“NDCs”), 
which are basically the proposed climate actions. The emission limit committed by Argentina, according to the 
information that emerges from the updated NDCs in October 2021, is not to exceed the net emission of 349 million 
tons of carbon dioxide equivalent (MtCO2e) in the year 2030. This goal is applicable to all sectors of the economy. 
 
The NDCs set forth that towards 2030, the Argentine Republic will carry out an energy transition, focusing 
its efforts on the promotion of energy efficiency, renewable energies, and the promotion of distributed generation, 
using natural gas as a transition fuel during this period. 
 
In order to follow up on this commitment -which aim is to contribute to the standards set forth in the Paris 
Agreement- Argentina must draft and report to the UNFCCC the National Green House Gases Inventory (INGEI for 
its acronym in Spanish). In addition, by means of Resolution No. 363/2021 issued by the Argentine Ministry of 
Environment and Sustainable Development, Argentina has created the National Registry of Climate Change 
Mitigation Projects, where the existing mitigation projects are registered. The scope of such register has not been 
determined as of the date of this annual report; therefore, its application cannot yet be defined.

Argentine Regulatory Framework in Connection with Climate Change 
 
The UNFCCC, which entered into force on March 21, 1994, aims to stabilize the GHG concentrations in 
the atmosphere to a level that would prevent dangerous anthropogenic interference with the climate system. 
 
On February 16, 2005, the Kyoto Protocol to the UNFCCC (“Kyoto Protocol”) entered into force. The 
Kyoto Protocol, which deals with the reduction of certain GHG emissions (carbon dioxide, methane, nitrous oxide, 
hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride) in the atmosphere, was in force until 2020 as a 
consequence of the ratification of the Doha Amendment to the Kyoto Protocol. 
 
Argentina approved UNFCCC by Federal Law No. 24,295 in December 1993, the Kyoto Protocol by 
Federal Law No. 25,438 on June 20, 2001, and the Doha Amendment by Federal Law No. 27,137 on April 29, 2015. 
 
The 2015 UN Climate Change Conference adopted by consensus the Paris Agreement, which is known to 
be the successor of the Kyoto Protocol (which was approved in Argentina by Federal Law No. 27,270). The Paris 
agreement deals with GHG emission reduction measures, targets to limit global temperature increases and requires 
countries to review and “represent a progression” in their intended nationally determined contributions. International 
treaties together with increased public awareness related to climate change may result in increased regulation to 
reduce or mitigate GHG emissions. 
 
Furthermore, Argentine Law No. 26,190, as amended and complemented by Law No. 27,191 and its 
implementing decrees, established a legal framework which promotes an increase in the participation of energies from 
renewable sources in Argentina’s electricity market. In this line, in 2019, the Argentine Congress enacted Law No. 
27,520 on Minimal Standards on Global Climate Change Adaptation and Mitigation, which focused on implementing 
policies, strategies, actions, programs and projects that can prevent, mitigate or minimize the damages or impacts 
associated with climate change. 
Moreover, the Argentine Registry of Climate Change Mitigation Projects was established (Argentine 
Environmental Ministry Resolution No. 363/2021). In addition, the SdE has set forth the “National Program for the 
Measurement and Reduction of Fugitive Emissions from Hydrocarbon Exploration and Production Activities” 
(Resolution No. 970/2023); the Argentine Ministry of Environment and Sustainable Development has approved the 
“Second National Plan for Adaptation and Mitigation to Climate Change” (Resolution No. 146/2023); the SdE has 
approved the “National Energy Transition Plan to 2030” (Resolution No. 517/2023) and the “Guidelines and 
Scenarios for the Energy Transition to 2050” (Resolution No. 518/2023). 
 
In addition, Resolution No. 23/2023, issued by the former Argentine Ministry of Environment, approved 
the Guide for the Preparation of Environmental Impact Studies incorporating the problem of climate change and the 
Guide on Public Participation in Environmental Evaluation. Implementation of these guides is voluntary. 
 
Under Law No. 27,191, by December 31, 2017, 8% of the electricity consumed must come from renewable 
sources, reaching 20% by December 31, 2025. It sets five stages to achieve the final goal: (i) 8% by December 31, 
2017; (ii) 12% by December 31, 2019; (iii) 16% by December 31, 2021; (iv) 18% by December 31, 2023; and (v) 
20% by December 31, 2025. It is within this framework that the Argentine government launched the RenovAr 
programs. As of December 31, 2024, electricity originated from renewable sources represented 16.3% of the total 
demand according to the data released by CAMMESA. 
 
At the provincial level, Neuquén has passed the Provincial Law No. 3,454 of August 2024 (Decree No. 
1039/2024), which established the principles and strategies corresponding to the public policies for climate change. 
It’s main objective is to encourage and promote a model of sustainable development, the transition to renewable 
energy, scientific and technological development and the involvement of citizens, private companies and non-
governmental organizations.

Mexico’s Oil and Gas Industry Overview 
According to the U.S. International Trade Administration, Mexico is the thirteenth largest producer of oil in 
the world and twenty-first in oil reserves. Mexico has significant hydrocarbon resources with estimated oil and gas 
proved developed and undeveloped reserves of 8.4 Bnboe and 3P reserves of 23.1 Bnboe, in each case as of 
December 31, 2023, according to the CNH. Multiple formations exist to develop productive fields. 
 
 
The Mexican subsurface has multiple geological plays and provides sizeable opportunities across the risk 
spectrum, from onshore mature fields to large deep-water projects. While oil and gas reserves are strongly 
concentrated in Southeast Basin plays, prospective resources are spread across multiple plays across several basins, 
which could lead to more opportunities for oil and gas participants to access previously untapped reservoirs.

Although the largest resources are in the offshore and shale plays, substantial potential still exists in onshore 
conventional reservoirs. Mexico’s shale resource base is among the largest in the world and is located only a few 
hundred miles away from the more developed U.S. shale plays with which the formations share many similarities. 
According to the EIA, technically recoverable shale resources, estimated at 545 Tcf of natural gas and 13.1 Bnbbl of 
oil, are potentially larger than the country’s proven conventional reserves. 
Multiple E&P plays across basins

92 
 
There were four principal means for private entities to invest in Mexico’s E&P sector: E&P Agreements, 
Pemex farm-outs agreement, E&P services contract and comprehensive services exploration and extraction contracts 
(“CSIEE”).  
The CNH was formerly entitled to allocate E&P Agreements, for which prequalification requirements were 
established, including operational, technical, financial, and legal capabilities. The bidding process was conducted by a 
committee of CNH members. Such tenders were discontinued at the end of 2018. In October 2021, the Mexican 
government presented the Five-Year Plan for 2020-2024, pursuant to which the previous administration determined 
that it would not undertake new bids to award contractual areas for E&P activities until the current contracts 
demonstrated profitability. The current administration has publicly maintained its position of not resuming CNH 
tenders. 
 
Farm-outs were a mechanism by which Pemex, as license holder, assigned an interest in the license to 
another party through a bidding process conducted by CNH in collaboration with Pemex. Pemex used farm-outs to 
partner with international E&P operators with the financial resources and expertise to accelerate development and 
extract value from its hydrocarbon asset base. The current administration has publicly maintained its position of not 
resuming farm-out tenders. 
 
Regarding E&P services contract migrations, Pemex was entitled to migrate existing oil and gas integrated 
E&P services contracts to production-sharing agreements or licenses to continue boosting investment in the E&P 
sector, transforming the relationship with Pemex from a service contractor model into a joint venture. These contracts 
were signed by Pemex and private companies before the energy reform under President Peña Nieto. The last E&P 
services contract migration took place in 2018. There were no migrations during the last presidential term, in which 
Pemex focused mostly on awarding a few CSIEE contracts.  
 
The current administration, led by President Claudia Sheinbaum since October 1, 2024, has prioritized 
economic activities in energy and sustainable development. In January 2025, citizen consultation forums were held to 
contribute to the construction of the 2025-2030 National Development Plan, which was submitted by President 
Sheinbaum to the Mexican House of Representatives for approval on February 28, 2025. The plan establishes that the 
fundamental target of oil production through Pemex, set at 1.8 million barrels per day, will continue to be domestic 
consumption. One of the plan’s main strategies is to increase hydrocarbon reserves in a sustainable manner through 
strategic E&P projects. Once published, this plan, along with the announced Pemex 2025-2030 Work Plan, will 
clarify key aspects of the current government’s stance on E&P activities. 
For additional context on the regulatory changes in Mexico, see “—Industry and Regulatory Overview—
Mexico’s Oil and Gas Industry Overview—Oil and Gas Regulatory Framework in Mexico.” 
Oil and Gas Regulatory Framework in Mexico  
Upstream and Downstream  
In 2013, the Mexican Constitution was amended leading to the opening of the oil, natural gas, and power 
sectors to private investment. In 2014, the Mexican Congress passed secondary laws to implement the reforms. The 
reforms allowed the Mexican government to grant contracts to private-sector entities in the upstream sector through 
public tenders. These amendments allowed private-sector entities to obtain permits for the processing, refining, 
marketing, transportation, storage, import and export of hydrocarbons.  
The legislation enacted in 2014 included the Mexican Hydrocarbons Law (Ley de Hidrocarburos), which 
preserved the concept of state ownership over hydrocarbons while located in the subsoil but allowed private 
companies to take ownership over the hydrocarbons once they were extracted. The Mexican Hydrocarbons Law 
allowed private-sector entities holding a permit granted by the Mexican Energy Regulatory Commission (Comisión 
Reguladora de Energía) (“CRE”) to store, transport, distribute, commercialize and carry out direct sales of 
hydrocarbons, as well as to own and operate pipelines and liquefaction, regasification, compression and de-

 
93 
 
compression stations or terminals, and related equipment in accordance with technical and other regulations. In 
addition, private-sector entities could import or export hydrocarbons subject to a permit from the SENER.  
However, on October 31, 2024, a constitutional reform was published in the Mexican Federal Official 
Gazette, redefining the nature and role of Pemex and CFE, strengthening state control over the energy sector, and 
orienting their operations toward public service and social welfare.  
Additionally, on December 20, 2024, a constitutional reform was published in the Mexican Federal Official 
Gazette, in terms of organic simplification, providing for the dissolution of various entities, including the COFECE, 
CRE and CNH. For additional context on the regulatory changes in Mexico concerning the COFECE, see “Item 3—
Key Information—Risk Factors—Detailed Risk Factors—Risks Related to the Argentine and Mexican Economic and 
Regulatory Environments—Measures adopted by the antitrust authority in Mexico could have a material adverse 
effect on our results and financial condition.”  
Lastly, on March 18, 2025, the Mexican Congress enacted new secondary legislation overhauling the energy 
sector and, thus, repealing and replacing the Mexican Hydrocarbons Law and several other federal statutes. For more 
information, see “—Energy Reform 2025.” 
Reserves and Resources Certification in Mexico  
On August 13, 2015, CNH published a set of guidelines that governs the valuation and certification of 
Mexico’s reserves and the related contingency resources. The CNH’s guidelines follow the same SPE/WPC/AAPG 
international standards as those described with respect to the reserves and resources certification process in Argentina 
(see “Item 4—Information on the Company—Industry and Regulatory Overview—Oil and Gas Regulatory 
Framework in Argentina—Reserves and Resources Certification in Argentina”). Therefore, the processes for reserves 
classification and certification in Mexico are similar to those described with respect to Argentina.  
Economic valuation criteria established by the CNH for proved reserves also follow the SEC’s definitions in 
Rule 4-10(a) of Regulation S-X which establishes that selling prices considered shall be the average price during the 
12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic 
average of the first day-of-the-month price for each month within such period.  
State Oil Company  
As a result of the energy reform sponsored by President Peña Nieto, Pemex was transformed from a 
decentralized public entity into a productive state-owned company on October 7, 2014. However, following the 
enactment of the Energy Reform 2025, Pemex’s status was changed from a productive state-owned company to a 
public state-owned company sectorized under SENER. Accordingly, Pemex remains wholly owned by the Mexican 
government. Moreover, the Energy Reform 2025 included the expedition of a new law governing Pemex (i.e., Ley de 
la Empresa Pública, Petróleos Mexicanos). Lastly, as a result of the Energy Reform 2025, Pemex’s productive 
subsidiaries, including Pemex-Exploración y Producción, were dissolved and merged into a single Pemex by 
operation of law. 
Energy Reform 2025 
On March 18, 2025, the Mexican Government enacted a reform of the energy sector (“Energy Reform 
2025”), comprising of new legislation comprising: (i) the Public State-Owned Company Law for CFE; (ii) the Public 
State-owned Company Law for Pemex; (iii) the Electric Sector Law; (iv) the Hydrocarbons Sector Law; (v) the 
Energy Planning and Transition Law; (vi) the Biofuels Law; (vii) the Geothermal Law; and (viii) the Mexican Energy 
Commission Law. In addition amendments were adopted to: (a) the Mexican Petroleum Fund for Stabilization and 
Development Law (Ley del Fondo Mexicano del Petróleo para la Estabilización y el Desarrollo); (b) the Organic 
Law of the Federal Public Administration (Ley Orgánica de la Administración Pública Federal) and (c) the 
Hydrocarbons Revenue Law (Ley de Ingresos Sobre Hidrocarburos). 

 
94 
 
The Energy Reform 2025 modifies the regulatory framework for the hydrocarbons and electricity sectors. It 
strengthens state-owned enterprises, reorganizes administrative structures, promotes energy self-sufficiency, and 
supports the transition to renewable energy.  
Furthermore, the Energy Reform 2025 introduces a new regulatory framework for CFE and Pemex to align 
with their revised constitutional status as public state-owned companies. It includes special provisions addressing 
their budgets, debt, subsidiaries and affiliates, sustainability, and contracting practices. The Energy Reform 2025 
provides that the activities of CFE and Pemex shall not be considered monopolistic and mandates the implementation 
of austerity measures, including the adoption of guidelines and execution programs with annual targets, financing 
mechanisms, and private sector participation under new regulations governing development schemes. In line with the 
foregoing, Pemex shall not be subject to the open access obligations applicable to the Mexican midstream industry, 
nor to the applicable unbundling obligations. 
 
The Energy Reform 2025 establishes that the exploration and extraction of hydrocarbons shall be carried out 
under three schemes. First, self-development entitlements (asignaciones para desarrollo propio), which shall be 
exclusively held by Pemex and under which Pemex shall be the sole operator. Pemex may, however, enter into 
service agreements with third parties, provided such agreements are structured to achieve the highest productivity and 
profitability, and the consideration is payable in cash. Second, the SENER may grant mixed development entitlements 
(asignaciones para desarrollo mixto). This scheme allows for private investment partnerships in projects led by 
Pemex, which must retain at least 40% participation. Private companies may contribute technical, operational, or 
financial expertise and may assume operatorship of the project. Under this scheme, private companies may recover up 
to 30% of costs—or up to 40% in exceptional cases, subject to the approval of Pemex’s board and SENER—and may 
share in up to 60% of project income, production, or profit, while also assuming part of the associated risks. Third, if 
Pemex is unwilling or unable to undertake hydrocarbons development under the aforementioned schemes, SENER 
may, on an exceptional basis, execute E&P Agreements. This scheme shall be subject to the issuance of bidding 
guidelines by SENER. Such agreements may take the form of service agreements, production-sharing agreements, 
profit-sharing agreements, or license agreements. 
 
 
Additionally, the Energy Reform 2025 underscores the importance of national energy security, public well-
being, and resource sustainability, positioning CFE and Pemex as key guarantors of energy production. However, 
until the corresponding secondary legislation is enacted, the full impact on the oil and gas industry remains uncertain. 
 
The Energy Reform 2025 has also entailed an administrative reorganization under which the functions of the 
CNH and the CRE have been transferred to SENER and to a newly established authority, the CNE. In this regard, it is 
noteworthy that SENER will exercise regulatory authority over the E&P sector. For example, authorizations for 
prospecting and exploration of hydrocarbons shall require SENER’s prior approval. Likewise, SENER shall be 
responsible for approving the modification, cancellation, and termination of E&P Agreements, as well as the 
corresponding exploration and development plans. 
 
Notably, the Energy Reform 2025 provides for the creation of the Mexican Energy Planning Council 
(Consejo de Planeación Energética), which will be responsible for ensuring binding and orderly planning, supporting 
the energy transition, and promoting sustainable energy practices. The reform also contemplates the development of a 
sectoral energy program, an energy transition plan, and specific development plans for both the electricity and 
hydrocarbons sectors. 
 
Lastly, pursuant to the transitional provisions of the Energy Reform 2025, the administrative provisions 
previously issued by the CRE and the CNH shall remain in force to the extent they do not conflict with the new laws. 
Regulations under the new Mexican Hydrocarbons Sector Law shall be issued within six months, during which time 
the existing regulatory framework will remain applicable. E&P Agreements shall continue to be governed by their 
original terms and conditions, in accordance with the legal provisions in effect at the time of their granting. Permits 
and authorizations previously issued by the CNH, CRE, and SENER shall remain valid under the terms and 
conditions under which they were granted.

Transportation  
Before the President Peña Nieto’s energy reform, Pemex had exclusivity on certain activities such as 
processing, storage, transportation, distribution and marketing of petroleum products. The aforesaid energy reform 
allowed private sector participation in the construction and operation of oil products storage and transportation 
facilities. In such regard, transportation activities required a permit issued by CRE and were subject to open access 
principles. Pursuant to the Energy Reform 2025, the CNE shall issue the corresponding transportation permits and the 
open access obligations shall remain in place and applicable to the shippers, with the exception of Pemex. Moreover, 
the Energy Reform 2025 provides that the creation of new integrated storage and transportation systems or the 
addition of new infrastructure thereof shall prioritize Pemex in the capacity assignment.  
Market Regulations  
In the past, the Mexican government has imposed price controls on the sales of natural gas, NGL, gasoline, 
diesel, gas oil intended for domestic use, fuel oil and other products. Nonetheless, currently, sale prices of gasoline 
and diesel have been fully liberalized and are determined by the free market. However, in late February 2025, 
President Claudia Sheinbaum’s administration entered into a voluntary agreement with gas station owners in Mexico 
to cap the price of regular gasoline at Ps.24 per liter for an initial period of six months. Such measure aimed at 
alleviating financial pressures on consumers. Said agreement excludes border regions due to their unique cost 
structures and fiscal incentives.  
The import and export of petroleum products, petrochemicals, and hydrocarbons, as well as their 
commercialization within Mexican territory, are regulated activities subject to permits issued by SENER and, 
previously, by CRE, respectively. Pursuant to the Energy Reform 2025, CRE’s  functions have been partially 
assumed by SENER, while several downstream-related responsibilities have been transferred to the newly established 
Mexican Energy Commission. Currently, in all onshore projects, private operators sell their entire hydrocarbon 
production domestically to Pemex. 
Federal Environmental Law  
The Mexican Federal Environmental Liability Law (Ley Federal de Responsabilidad Ambiental) enacted on 
July 7, 2013 regulates environmental liability arising from damages to the environment including remediation and 
compensation. In the event of intentional and unlawful action or inaction, the responsible party will be fined up to 
approximately 68 million Mexican Pesos for 2025. This liability regime is independent from administrative, civil or 
criminal liability regimes, which may be applicable depending on the performed conduct.  
Environmental liability may be attributed to an entity for conduct carried out by its representatives, 
managers, directors, employees, or officers who are directly involved in operations. The statute of limitations to claim 
environmental liability is 12 years from the date of the environmental damage. The law allows the interested parties to 
solve disputes by means of alternative dispute resolution mechanisms, provided that public interest or third-party 
rights are not affected.  
Mexican Judicial Reform 
On September 15, 2024, a constitutional reform was published in the Mexican Federal Official Gazette, 
introducing significant changes to Mexico’s judicial system (“Mexican Judicial Reform”). The reform mandates the 
popular election of judges, magistrates, and Supreme Court justices. It has faced strong opposition from the judiciary, 
leading to nationwide strikes from August 19, 2024, to October 30, 2024. These disruptions have affected judicial 
proceedings, potentially causing delays in litigation and dispute resolution.

ORGANIZATIONAL STRUCTURE 
The following diagram shows our main subsidiaries as of December 31, 2024:  
 
 
(1) As of the date of this annual report, AFBN, Aleph Midstream, and Vista Holding VII S.A.U. are in the process of being merged into our 
subsidiary Vista Argentina. For information regarding the merger, please see “Item 4—Information on the Company—Recent 
Developments—Corporate Reorganization.” 
(2) Assets transferred to Aconcagua, effective on March 1, 2023. 
 
 
 
PROPERTY, PLANT AND EQUIPMENT 
We hold both freehold and leasehold interests, but no specific interest is individually material to us. Most of 
our property, consisting of oil and gas reserves, oil and gas wells and corporate office buildings are located in 
Argentina. In each of the countries in which we operate, the states (federal or provincial) are the exclusive owner of 
all hydrocarbon resources located in such country and have full authority to determine the rights, royalties or 
compensation to be paid by private investors for the exploration or production of any hydrocarbon reserves. 
In Argentina, the Provinces are the exclusive owners of all onshore hydrocarbon resources and have full 
authority to determine the rights, royalties or compensation to be paid by private investors for the exploration or 
production of any hydrocarbon reserves. The Provinces grant these rights through exploitation concessions. In 
Mexico, prior to the Energy Reform 2025, the Mexican State performed E&P activities through entitlements, granted 
to public state-owned companies, or by granting public state-owned companies or private entities, individually or 
under a consortium, E&P agreements. With the implementation of the Energy Reform 2025, the Mexican State may 
carry out E&P activities through self-development entitlements (asignaciones para desarrollo propio) or mixed 
development entitlements (asignaciones para desarrollo mixto) granted to Pemex, or, on an exceptional basis, 

 
97 
 
through E&P agreements awarded pursuant to a public bidding process conducted by SENER. Entitlements and E&P 
agreements are subject to different regulatory regimes. For more information, see “—Industry and Regulatory 
Overview—Oil and Gas Regulatory Framework in Argentina” and “—Industry and Regulatory Overview—Oil and 
Gas Regulatory Framework in Mexico.” 
We are subject to several environmental laws and regulations promulgated by local and federal governments 
in Argentina and Mexico which may affect the utilization of the assets. In addition, other environmental issues may 
influence the Company’s use of property, plant and equipment. See “Item 3—Key Information—Risk Factors—
Detailed Risk Factors—Risks Related to Our Business and Industry—The oil and gas industry is subject to particular 
operational and economic risks” and “—ESG Matters.”

(1)  We calculate Adjusted EBITDA as profit for the year, net, plus income tax expense, financial income (expense), net, depreciation, 
depletion and amortization, transaction costs related to business combinations and gain from asset disposals, restructuring and 
reorganization expenses, gain related to the transfer of conventional assets, other non-cash costs related to the transfer of conventional 
assets and (reversal) impairment of long- lived assets. We present Adjusted EBITDA because we believe it provides investors with a 
supplemental measure of the financial performance of our core operations that facilitates period to period comparisons on a consistent 
basis. Our management uses Adjusted EBITDA, among other measures, for internal planning and performance measurement purposes. 
Adjusted EBITDA is not a measure of liquidity or operating performance under IFRS and should not be construed as an alternative to 
net profit, operating profit, or cash flow provided by operating activities (in each case, as determined in accordance with IFRS).  See 
“Presentation of Information—Non-IFRS Financial Measures.” 
(2)  We calculate Adjusted EBITDA Margin as the ratio of Adjusted EBITDA to revenue from contracts with customers plus Gain from 
Exports Increase Program. See “Presentation of Information—Non-IFRS Financial Measures.” 
(3) 
We calculate Adjusted Net Income as profit for the year, net, plus deferred income tax (expense), changes in fair value of warrants, gain 
related to the transfer of conventional assets, other non-cash costs related to the transfer of conventional assets and (reversal) 

 
99 
 
impairment of long- lived assets. We add back these four adjustments since they are non-cash items that do not reflect the fair net 
income generation of the Company. See “Presentation of Information—Non-IFRS Financial Measures.” 
(4)    We calculate ROACE as Adjusted EBITDA, plus depreciation, depletion and amortization, gain related to the transfer of conventional 
assets and other non-cash costs related to the transfer of conventional assets, divided by the sum of the average total debt and average 
total shareholders’ equity. For purposes of this definition, total debt is comprised of current borrowings, non-current borrowings, current 
lease liabilities and non-current lease liabilities. See “Presentation of Information—Non-IFRS Financial Measures.”

Source of Revenues  
Vista is principally engaged in the oil and gas E&P business. Our oil and gas operations derive revenues 
mainly from the production and sale of crude oil, natural gas, and NGL. During the year ended December 31, 2024, 
oil sales contributed 95.5% of our total revenues, natural gas sales contributed 4.3% of our total revenues and NGL 
sales contributed 0.2% of our total revenues. During the year ended December 31, 2023, oil sales contributed 93.9% 
of our total revenues, natural gas sales contributed 5.8% of our total revenues and NGL sales contributed 0.3% of our 
total revenues. During the year ended December 31, 2022, oil sales contributed 93.7% of our total revenues, natural 

 
101 
 
gas sales contributed 5.8% of our total revenues and NGL sales contributed 0.5% of our total revenues. During 2024, 
2023 and 2022, most of our revenues were generated in Argentina. 
Our sales volumes impact directly our results of operations. As reservoir pressure declines, production from 
a given well, or group of wells, in a formation decreases. Growth in our future production and reserves will depend on 
the development of our acreage and the corresponding capital expenditure, which will determine our ability to add 
proved reserves in excess of our production. Accordingly, we plan to maintain our focus on adding reserves by further 
drilling our shale oil acreage in Vaca Muerta. Our ability to add reserves through acquisitions is dependent on many 
factors, including prevailing market conditions and our ability to raise capital, obtain regulatory approvals, procure 
drilling rigs and personnel and successfully identify and consummate acquisitions.  
Our business is inherently volatile due to the influence of external factors, such as domestic and international 
demand, market prices, availability of financial resources for our business plan and its corresponding costs and 
government regulations. Consequently, our past financial condition, results of operations and the trends indicated by 
such results and financial condition may not be indicative of current or future financial conditions, results of 
operations or trends.  
We sell our oil and gas to many creditworthy purchasers. Since our production is sold in the commodities 
market, where several customers or markets are accessible to us, we do not believe the loss of any customer would 
have a material adverse effect on our business.  
Production Results and Other Operating Data  
The following table sets forth summary unaudited information about the oil and natural gas historical 
production volumes and other relevant operating and financial data of the assets we own in Argentina and Mexico. 
For the year ended December 31, 2024, the historical production volumes and other relevant operating data included 
below were calculated at their respective working interest percentages. Royalties payable to the Provinces have not 
been deducted from our net production amounts given that substantially all of our production is currently in Argentina 
and under Argentine law royalties constitute a production tax payable in cash (and do not give the Provinces a direct 
interest in such production to make lifting and sales arrangements independently). We account for royalties as cost of 
sales.

(1) Measured based on our working interest. There was no production due to others during the applicable periods. Oil production is 
comprised of production of crude oil, condensate and natural gasoline. Natural gas production excludes natural gas consumption. NGL 
production is comprised of production of propane and butane (LPG) and excludes natural gasoline.  
(2) We calculate average unit costs per boe by dividing operating costs, royalties or depreciation, depletion and amortization for the 
relevant period, as applicable, by average daily net production multiplied by days in each period (365 days for 2022, 365 days for 2023 
and 366 days for 2024).  
(3) Measured based on our working interest. Royalties are applied to the total production of the concessions, and are calculated by applying 
the applicable royalty rate to the production, after discounting certain expenses in order to obtain the value of crude oil, natural gas and 
liquefied gas volumes at the wellhead.

Factors Affecting our Results of Operations 
Our operations are affected by a number of factors, including:  
(i) 
the volume of crude oil, natural gas and liquid gas we produce and sell; 
(ii) 
pricing dynamics and pricing regulation;  
(iii) 
hydrocarbon export regulations set by the Argentine and Mexican governments and domestic 
supply requirements;  
(iv) 
international and domestic prices of crude oil and oil products;  
(v) 
discount of our oil production to market prices;  
(vi) 
our capital expenditures and financing availability;  
(vii) 
supply chain dynamics and cost increases;  
(viii) market demand for hydrocarbon products;  
(ix) 
operational risks, labor strikes and other forms of public protest;  
(x) 
taxes, including export taxes;  
(xi) 
regulation of capital flows;  

 
103 
 
(xii) 
exchange rates;  
(xiii) interest rates; and 
(xiv) 
changes to demand for hydrocarbon products and related services as the result of global trends 
such as conflicts, pandemics and consumer behavior. 
Our business is inherently volatile due to the influence of external factors, such as domestic demand, market 
prices, availability of financial resources for our business plan and its corresponding costs and government 
regulations and policies. Consequently, our past financial condition, results of operations and trends indicated by such 
results and financial condition may not be indicative of current or future financial conditions, results of operations or 
trends.  
Discovery and Exploitation of Reserves  
Our results of operations depend to a large extent on our level of success in the development of our shale oil 
acreage. While we have geological reports evaluating certain proved, contingent and prospective reserves in our 
blocks, there is no assurance that we will continue to be successful in the exploration, appraisal, development and 
commercialization of oil and gas. The calculation of our geological and petrophysical estimates is complex and 
imprecise, which means it is possible that our future exploration or appraisal in undeveloped acreage will not result in 
additional discoveries, and, even if we are able to successfully make such discoveries, it is uncertain whether the 
discoveries will be commercially viable to produce. 
Funding our capital expenditures partially relies on oil prices remaining close to, or higher than, our 
estimates together with other factors to generate sufficient cash flow. Low oil prices may affect our revenues, which 
in turn may affect our debt capacity and our capacity to remain within the leverage ratios defined in the covenants in 
our financing agreements, as well as our cash flow from operations. Our operations, investor confidence and share 
price could be adversely affected if we are not able to generate enough cash flows to fund our future operating 
expenses and capital expenditures.  
If average realized oil prices are higher than expected, we would have the ability to allocate additional 
capital to engage in new projects, potential acquisition opportunities and accelerate the pace of existing operations, in 
all cases leading to a potential increase in our oil and gas production and cash flows.  
Our operations results would be adversely affected in the event that our oil and natural gas reserves and the 
capital return do not meet our expectations. In addition, we focus on several factors when analyzing new investment 
in our blocks or potential acquisitions. As a consequence, it is uncertain whether we will focus on the development of 
our current assets or make any acquisitions to increase our current production and reserves. Our business, results from 
operations and financial condition may be materially affected if we do not deploy the necessary capital expenditures 
to increase the reserves of our current blocks or increase our reserves through profitable acquisition opportunities.  
Availability and Reliability of Infrastructure  
Our business depends on the availability and reliability of operating, gathering and treatment facilities in the 
areas we operate, and the expansion of midstream capacity to take hydrocarbon production to our customers. Prices, 
together with the availability of equipment and infrastructure, with the corresponding maintenance thereof, affect our 
ability to follow our investment plan to operate our business, and thus our operations results and financial condition. 
See “Item 4—Information on the Company—Business Overview—Transportation and Treatment.” 
Contractual Obligations  
Unconventional concessions have 35-year terms under the Argentine Hydrocarbons Law. To maintain our 
exploitation rights granted by the provincial executive branch, we are required to comply with certain investment 
commitments, typically related to the drilling and completion of new wells as per a project pilot approved by the 
provincial executive branch. These pilots must be executed within a fixed timeframe, typically between three and five 
years. Operating and maintenance costs may increase significantly due to adverse local or international market 
conditions, such as local recession, foreign exchange volatility, or high financing costs, which could hinder our ability 
to meet these investment commitments within the agreed timeframe on commercially reasonable terms, or at all. A 

 
104 
 
substantial and unjustified failure to comply with such investment commitments could ultimately lead to the forfeiture 
of our exploitation rights, with the provincial executive branch declaring the expiration of the concession, which 
could materially impact our ability to grow our business. See “Item 5.A Operating Results—Factors Affecting our 
Results of Operations—Contractual Obligations.”  
The Argentine and Mexican Economies  
Our financial condition and results of operations depend to a significant extent on macroeconomic and 
political conditions prevailing from time to time in Argentina, and to a lesser extent in Mexico.  
The general performance of the Argentine economy affects the demand for energy, while inflation, 
fluctuations in currency exchange rates and social stability affect our costs and our margins. Inflation primarily affects 
our business by increasing operating costs in Argentine Pesos.

Most of our sales are directly denominated in U.S. Dollars or indexed to the U.S. Dollar. We collect a 
significant portion of our revenues in Argentine Pesos pursuant to prices which are indexed to the U.S. Dollar, mainly 
revenues resulting from the sale of crude oil and natural gas, which sales are invoiced in U.S. Dollars using the U.S. 
Dollar/Argentine Peso exchange rate as of the date of issuance of the invoice payable within a 15- to 57-day payment 
period. However, our invoices are subject to adjustment to the prevailing U.S. Dollar/Argentine Peso exchange rate in 
effect as of the date of payment. Any significant increase in the Argentine Peso price as a result of a decline in the 
Argentine Peso/U.S. Dollar exchange rate could lead to decreased sales volumes as a result of increases in the 
effective price in Argentine Pesos paid by our customers for natural gas and crude oil. We are exposed to the risk that 
purchasers of our natural gas and crude oil may be unable to pay amounts owed to us following a material devaluation 
of the Argentine Peso. 
 
Argentine Foreign Exchange Regulations 
Since September 1, 2019, different Argentine governments with the purpose of strengthening the normal 
functioning of the economy, fostering a prudent administration of the exchange market, reducing the volatility of 
financial variables, and containing the impact of the variations of financial flows on the real economy, foreign 
exchange controls were reinstated in Argentina. However, Javier Milei’s administration has changed the 
macroeconomic program to focus on eliminating the federal government’s fiscal deficit and substantially reducing 
monetary issuance. Despite President Milei announcing that exchange controls would be lifted by the end of 2025, 
which is one of the main objectives of the current government, no official plan nor timeline for this event has been 
disclosed. See “Item 10—Additional Information—Exchange Controls.” 
The value of the Argentine Peso compared to other currencies depends, among other factors, on the level of 
international reserves held by the BCRA, which have also shown significant fluctuations in recent years, as well as on 
the fiscal and monetary policies adopted by the Argentine government. The Argentine macroeconomic environment, 
in which we operate, was affected by the continuous depreciation of the Argentine Peso, which in turn had a direct 
impact on our financial and economic position. See “Item 3—Key Information—Risk Factors—Detailed Risk 
Factors—Risks Related to our Company—We are exposed to foreign exchange risks related to our operations in 
Argentina and Mexico.” 
Policy and Regulatory Developments in Argentina and Mexico 
The Argentine and Mexican oil and gas industry have been subject to reforms during the past five years and 
there can be no assurance that future reforms or reversal of existing ones will not have an adverse impact on our 
revenues and results of operations. Our business is, to a large extent, dependent upon regulatory conditions prevailing 

 
106 
 
in the countries in which we operate, and our results of operations may be materially and adversely affected by 
regulatory changes in these countries. Additionally, the regulatory burden on the oil and gas industry increases the 
cost of doing business in the industry and consequently affects profitability.  
For more information regarding policy and regulatory developments relating to the oil and gas industry in 
Argentina, see “Item 4—Information on the Company—Industry and Regulatory Overview—Argentina’s Oil and Gas 
Industry Overview.” For more information regarding policy and regulatory developments relating to the oil and gas 
industry in Mexico, see “Item 4—Information on the Company—Industry and Regulatory Overview—Mexico’s Oil 
and Gas Industry Overview.”  
Seasonality  
Although there is some historical seasonality to the prices that we are paid for our production, seasonality 
does not play a significant role in our ability to conduct our operations, including drilling and completion activities as 
planned in our budgets. For example, seasonal demand behavior during winter and autumn affects the prices that we 
receive for our production. However, the impact of such seasonality has historically not been material.  
Warrants  
Under IFRS, a contract to issue a variable number of common shares, such as warrants, should be classified 
as a financial liability and measured at fair value, with changes in fair value recognized in the consolidated statement 
of profit or loss and comprehensive income. On March 2, 2023, Vista concluded the process with the CNBV to 
update the registration of Vista’s warrants in the RNV. These warrants have been accounted for as a liability and are 
subject to adjustment of their fair market value at each reporting period. The determination of fair market value is 
subject to assumptions and estimates and changes to these assumptions and estimates could impact the valuation of 
the warrants, which could in turn have an effect on our consolidated statement of profit or loss and comprehensive 
income. On March 15, 2023, Vista exercised all outstanding warrants on a cashless basis resulting in the early 
termination of all outstanding warrants. Holders of the warrants received one series A share for every 31 warrants 
owned by each holder. Holders only received whole series A shares (not fractions). In addition, holders of warrants 
received a payment in Mexican Pesos for any fractions held by them. As of the date of this annual report, there are no 
outstanding warrants. 
Deferred Income Tax 
Under IFRS, the difference between the book value of property, plant and equipment (measured in U.S. 
Dollars, our functional currency) and the tax basis of such property, plant and equipment (which tax basis is 
expressed in Argentine Pesos or Mexican Pesos, as applicable, and may not be re-valued due to foreign exchange 
fluctuations under applicable tax laws) is a temporary difference to be considered in the calculation of deferred 
income tax. For more information, see Note 2.4.14.2 to our Audited Financial Statements. In addition to property, 
plant and equipment, we recognize deferred tax assets with respect to the temporary difference between the 
accounting and tax basis of the well plugging and abandonment provisions relating to our oil and gas properties.  
On December 29, 2017, the Argentine government enacted Law No. 27,430 which introduced several 
changes to the Argentine ITL (as defined below) as well as to other federal taxes. Pursuant to Law No. 27,430 the 
income tax rate for Argentine companies would be gradually reduced from 35% to 30% commencing on tax periods 
initiated after January 1, 2018 and through December 31, 2019, and to 25% commencing on tax periods initiated after 
January 1, 2020 (an additional income tax withholding on actual or presumed dividend distributions to Argentine 
resident individuals or to foreign resident shareholders was also enacted at a 7% and 13% rate, respectively, so that an 
aggregate 35% tax burden is completed). On December 23, 2019, the Solidarity Law was published in the Argentine 
Official Gazette, providing –among many other federal tax aspects, including the creation of the so-called “PAIS 
Tax”- the suspension of the application of the 25% corporate tax rate for one tax period. Pursuant to further 
clarifications unofficially made by the Argentine tax authorities, the 25% corporate tax rate (coupled with the 13% 
income tax withholding on actual or presumed dividend distributions of profits) would be applicable as of tax periods 
initiated after January 1, 2021. Through Law No. 27,630, the income tax rate applicable to Argentine companies is 
again modified, establishing a progressive tax rate system with a rate of 25% to 35% based on the accumulated net 
taxable income and a 7% withholding applicable to any distribution of dividends or profits made by such entities to 
individuals’ resident in Argentina and to beneficiaries abroad, regardless of the tax period in which such dividends or 

 
107 
 
profits are made available to the shareholders. These amendments are applicable to tax periods beginning on or after 
January 1, 2021. Despite these changes, there are many transactions and calculations for which the ultimate tax 
determination is still uncertain. We recognize liabilities for potential tax claims based on estimates of whether 
additional taxes will be due in the future. For more information, see Note 2.4.14 to our Audited Financial Statements.  
Depreciation, Depletion and Amortization  
IFRS requires us to make estimates and assumptions that affect reported amounts of assets, liabilities, 
revenues and expenses, among other line times, relating to our oil and gas properties. Actual results could differ from 
such estimates. Depreciation, depletion and amortization rates can fluctuate as a result of development costs, 
acquisitions, impairments, as well as changes in proved reserves or proved developed reserves. For more information, 
see Note 2.4.2.1 and 2.4.4 of our Audited Financial Statements.  
Oil and Gas Market Conditions  
The oil and gas industry is cyclical, and commodity prices are highly volatile. Following the oil price crash 
during the COVID-19 pandemic, global oil prices returned to pre-pandemic levels by early 2022. In the first half of 
2022, Brent crude oil prices increased, driven by the ongoing conflict between Russia and Ukraine, which led to 
sanctions from several countries, including the United States and European Union member states. These sanctions 
raised concerns about global energy supply, as Russia was the world’s third-largest oil producer and the largest oil 
exporter. As a result, Brent crude oil prices rose from US$77.8/bbl on December 31, 2021, to US$85.9/bbl on 
December 31, 2022, with an annual average of US$99.0/bbl, representing a 39% increase year-over-year. 
 
In 2023, oil demand growth was lower than expected due to weaker economic growth and rising interest 
rates, leading to a decline in Brent crude oil prices from US$85.9/bbl on December 31, 2022, to US$77.0/bbl on 
December 31, 2023, with an annual average of US$82.3/bbl, a 17% decrease year-over-year. 
 
During 2024, oil demand growth remained below expectations. Combined with stronger non-OPEC supply 
growth, this contributed to a further decline in Brent crude oil prices from US$77.0/bbl on December 31, 2023, to 
US$74.6/bbl on December 31, 2024, with an annual average of US$79.8/bbl, representing a 3% decrease year-over-
year.  
It is likely that commodity prices will continue to fluctuate due to global supply and demand, inventory 
supply levels, weather conditions, geopolitical and other factors. Additionally, the oil and gas industry is subject to a 
number of operational trends, some of which affect the basins where we operate. Oil and gas companies are 
increasingly utilizing new techniques to lower drilling costs and increase efficiency of operations.  
The operating results and cash flows of our business are susceptible to risks related to the volatility of 
international oil prices. Due to regulatory, economic and government policy factors, oil prices in Argentina in the past 
have lagged behind the prevailing prices in the international market. Furthermore, Argentina’s government has 
imposed export duties and other restrictions on exports in the past that have prevented companies from benefiting 
from the full increase in international oil prices. During 2022, the average annual Brent crude oil price stood at 
US$99.0/bbl, and our average realization price was US$72.3/bbl, 27% below the average annual Brent crude oil price 
and 22% below export parity for Medanito oil price, which stood at US$92.7/bbl. During 2023, the average annual 
Brent crude oil price stood at US$82.3/bbl, and our average realization price was US$66.7/bbl, 19% below the 
average annual Brent crude oil price and 7% below export parity for Medanito oil price, which stood at US$72.0/bbl. 
During 2024, the difference between our average realized price and export parity for Medanito oil narrowed to 2%.   
The price of natural gas in Argentina has been regulated by a series of government measures intended to 
ensure domestic supply at affordable prices for end consumers. Therefore, gas producers can elect to sell natural gas 
to distribution companies in the regulated market at prices established by the relevant authorities. As of December 31, 
2024, we sold 9.0 million MMBtu to the regulated internal market under Plan GasAr. See “Item 4—Information on 
the Company—Industry and Regulatory Overview— Oil and Gas Regulatory Framework in Argentina—Plan GasAr 
2020-2024.” Alternatively, gas producers can also (or only) sell their surplus gas production on the deregulated 
market, either in Argentina or potentially, and subject to meeting certain requirements, through exports. Historically, 
gas prices in the regulated market have lagged the deregulated and regional market prices. However, this has been 
reverted during 2023 and 2024. In 2024, our average realization price in the regulated market (i.e., Plan GasAr) was 

 
108 
 
US$3.3/MMBtu and our average realization price in the domestic deregulated market (i.e., sales to industrial clients) 
was US$1.9/MMBtu.

A sustained drop in oil, natural gas and NGL prices may not only decrease our revenues but may also reduce 
the amount of oil, natural gas and NGL that we can produce economically and therefore potentially lower our oil, 
natural gas and NGL reserve quantities.

Revenue from contracts with customers 
The detail of our revenues from contracts with customers is the following:  
Types of goods 
For the year ended 
December 31, 2024 
For the year ended 
December 31, 2023 
Revenues from crude oil sales.......................................................
1,573,069 
1,097,316 
Revenues from natural gas sales ....................................................
71,756 
67,290 
Revenues from NGL sales............................................................
2,943 
4,168 
Revenue from contracts with customers.......................................
1,647,768 
1,168,774 
 
Total revenue from contracts with customers increased to US$1,647.8 million during the year ended 
December 31, 2024, compared to US$1,168.8 million during the year ended December 31, 2023. Such increase was 
mainly driven by oil production growth. 
 
Revenues from crude oil increased to US$1,573.1 million during the year ended December 31, 2024, 
compared to US$1,097.3 million during the year ended December 31, 2023, which represented 96% and 94% of our 
total revenue from contracts with customers, respectively. Such increase was primarily driven by an increase in oil 
sales volumes of 39% and an increase in realized crude oil price of 4% year-over-year.  
Total volume of crude oil sold increased to 21.9 MMbbl during the year ended December 31, 2024, 
compared to 15.7 MMbbl during the year ended December 31, 2023, mainly driven by a 36% production growth 
year-over-year, which in turn resulted from 50 shale oil wells tied-in during 2024, increasing the total number of 
cumulative shale wells tied-in to 149 at year-end. This activity boosted oil production, which increased 39% year-
over-year during 2024. 
Average realized crude oil sales prices increased to US$69.2/bbl during the year ended December 31, 2024, 
compared to US$66.7/bbl during the year ended December 31, 2023. Such increase was mainly driven by a 12% 
increase in domestic prices (including 37% of domestic volumes sold at export parity prices, up from 9% during 
2023) and partially offset by a decrease in export prices of 2%.  
In 2024, 10.6 MMbbl of crude oil, or 49% of total crude oil volumes, were sold to export markets for a total 
revenue of US$807.5 million, which, net of export duties of US$59.5 million, amounted to US$748.0 million. In 
2023, 8.2 MMbbl of crude oil, or 52% of total crude oil volumes, were sold to export markets for a total revenue of 
US$642.2 million, which, net of export duties of US$48.4 million, amounted to US$593.8 million. Combining sales 
to international and domestic markets, 68% of our sales were conducted at export parity prices, an increase from 57% 
in 2023. 
Revenues from natural gas increased to US$71.8 million during the year ended December 31, 2024, 
compared to US$67.3 million during the year ended December 31, 2023, which represented 4% and 6% of our total 
revenue from contracts with customers, respectively. Such increase was primarily driven by a 17% increase in natural 
gas sales volumes and partially offset by a 9% decrease in realized natural gas prices. 
Total volume of natural gas sold increased to 3.9 MMboe during the year ended December 31, 2024, 
compared to 3.3 MMboe during the year ended December 31, 2023.  
The average realized natural gas sales price was US$3.2/MMBtu during the year ended December 31, 2024, 
a 9% decrease compared to US$3.5/MMBtu during the year ended December 31, 2023. Such decrease was mainly 
driven by lower prices to industrial customers at US$1.9/MMBtu in 2024, compared to US$2.3/MMBtu in 2023. 
Revenues from NGL decreased to US$2.9 million during the year ended December 31, 2024, compared to 
US$4.2 million during the year ended December 31, 2023, which represented less than 1% of our total revenue from 
contracts with customers during both periods.  

 
 
111 
 
During the year ended December 31, 2024, 99% of our revenue was generated by our oil and gas properties 
in Argentina, as well as during the year ended December 31, 2023.

Cost of sales increased to US$830.0 million during the year ended December 31, 2024, compared to 
US$577.5 million during the year ended December 31, 2023. Total cost of sales included operating costs, fluctuations 
in the inventory of crude oil, depreciation, depletion and amortization, royalties and others, and other non-cash costs 
related to the transfer of conventional assets.  
Operating costs increased to US$116.5 million during the year ended December 31, 2024, compared to 
US$94.7 million during the year ended December 31, 2023, which represented 14% and 16% of our total cost of 
sales, respectively. Operating costs per produced barrel decreased to US$4.6/boe during the year ended December 31, 
2024, from US$5.1/boe during the year ended December 31, 2023. This decrease was primarily driven by the dilution 
of fixed costs due to production growth and partially offset by inflation in U.S. Dollars impacting Argentine Peso-
denominated expenditures.  
The crude oil stock fluctuation increased to a gain of US$1.7 million during the year ended December 31, 
2024, compared to a loss of US$2.1 million during the year ended December 31, 2023. This was primarily due to the 
increase in crude oil stock at the end of the period. 
Depreciation, depletion and amortization increased to US$437.7 million during the year ended December 31, 
2024, compared to US$276.4 million during the year ended December 31, 2023, which represented 53% and 48% of 
our total cost of sales, respectively. This increase was primarily driven by higher capital expenditures and total 
production in 2024 compared to 2023. 
Royalties and others increased to US$244.0 million during the year ended December 31, 2024, compared to 
US$176.8 million during the year ended December 31, 2023, which represented 29% and 31% of our total cost of 
sales, respectively. This increase was primarily driven by the above-mentioned increase in crude oil production and 
prices.  
Other non-cash costs related to the transfer of conventional assets was US$33.6 million during the year 
ended December 31, 2024, compared to US$27.5 million during the year ended December 31, 2023, which 
represented 4% and 5% of our total cost of sales, respectively. These non-cash were mainly related to the 
Conventional Assets Transaction. 
Gross Profit  
Gross profit increased to US$817.7 million during the year ended December 31, 2024, compared to 
US$591.2 million during the year ended December 31, 2023, which represented 50% and 51% of our total revenue 
from contracts with customers, respectively.  
Selling Expenses  
Selling expenses increased to US$140.3 million during the year ended December 31, 2024, compared to 
US$68.8 million during the year ended December 31, 2023, which represented 9% and 6% of our total revenue from 

 
 
112 
 
contracts with customers, respectively. This increase was primarily driven by an increase of 167% in transport costs 
due to a higher amount of crude oil volumes transported by trucks in 2024 compared to 2023. 
General and Administrative Expenses  
General and administrative expenses increased to US$109.0 million during the year ended December 31, 
2024, compared to US$70.5 million during the year ended December 31, 2023, which represented 7% and 6% of our 
total revenue from contracts with customers, respectively. This increase was primarily driven by a 61% increase in 
salaries and payroll taxes, a 51% increase in share-based payments and a 414% increase in taxes, rates and 
contributions, in all cases during 2024 compared to 2023. 
Exploration Expenses  
Exploration expenses increased to US$0.14 million during the year ended December 31, 2024, compared to 
US$0.02 million during the year ended December 31, 2023. 
Other Operating Income  
Other operating income decreased to US$54.1 million during the year ended December 31, 2024, compared 
to US$203.8 million during the year ended December 31, 2023. This decrease was mainly driven by (i) no gains 
related to the Conventional Assets Transaction in 2024, compared to US$89.7 million in 2023, (ii) US$36.0 million of 
lower gains from the Exports Increase Program, and (iii) US$24.4 million lower gains related to the gain from the 
Farm-out Agreements with Trafigura.  
Other Operating Expenses  
Other operating expenses resulted in a loss of US$1.3 million during the year ended December 31, 2024, 
compared to a gain of US$0.3 million during the year ended December 31, 2023.  
Impairment of Long-lived Assets 
Impairment of long-lived assets resulted in a gain of US$4.2 million during the year ended December 31, 
2024, related to  the concessions CS-01 in Mexico, compared to a loss of US$24.6 million during the year ended 
December 31, 2023.  
Operating Profit  
Operating profit decreased to US$625.4 million during the year ended December 31, 2024, compared to 
US$631.5 million during the year ended December 31, 2023, which represented 38% and 54% of our total revenue 
from contracts with customers, respectively.  
Interest Income  
Interest income increased to US$4.5 million during the year ended December 31, 2024, compared to US$1.2 
million during the year ended December 31, 2023.  
Interest Expense  
As of December 31, 2024, the interest expense increased to US$62.5 million from US$21.9 million for the 
year ended December 31, 2023. This increase was primarily due to new debt issuances at a higher interest rate.  
Other Financial Results  
Other financial results totaled a gain of US$23.4 million for the year ended December 31, 2024, compared to 
a loss of US$65.5 million for the year ended December 31, 2023. This change was primarily driven by the 
remeasurement of borrowings arising from financial liabilities incurred in Argentina, adjusted by the reference 

 
 
113 
 
stabilization ratio (“UVA”), recorded in 2023, and a 156% decrease in other financial results, partially offset by a 
102% increase in net foreign exchange rate changes.   
Profit Before Income Taxes  
Profit before income taxes totaled US$590.8 million during the year ended December 31, 2024, compared to 
US$545.4 million during the year ended December 31, 2023.  
Income Tax expense  
Our income tax expenses totaled US$113.3 million during the year ended December 31, 2024, compared to 
US$148.4 million during the year ended December 31, 2023. This change was primarily driven by a net effect of (i) 
an increase in current income tax expenses from US$16.4 million in 2023 to US$426.3 million in 2024, and (ii) a 
decrease in deferred income tax, from a an expense of US$132.0 million in 2023 to a gain of US$312.9 million in 
2024, mainly driven by the deferred tax inflation adjustment from our main subsidiary Vista Argentina, and the 
depreciation of the Argentine Peso with respect to the U.S. Dollar affecting the Company’s tax deductions of 
nonmonetary assets.  
Profit for the year, net  
During the year ended December 31, 2024, the profit for the year, net totaled US$477.5 million, compared to 
US$397.0 million during year ended December 31, 2023.

Revenue from contracts with customers 
The detail of our revenues from contracts with customers is the following:  
Types of goods 
For the year ended 
December 31, 2023 
For the year ended 
December 31, 2022 
Revenues from crude oil sales.......................................................
1,097,316 
1,113,411

1,187,660 
 
Total revenue from contracts with customers decreased to US$1,168.8 million during the year ended 
December 31, 2023, compared to US$1,187.7 million during the year ended December 31, 2022. Such decrease was 
mainly driven by lower realized oil prices, partially offset by oil production growth. 
 
Revenues from crude oil decreased to US$1,097.3 million during the year ended December 31, 2023, 
compared to US$1,113.4 million during the year ended December 31, 2022, which represented 94% of our total 
revenue from contracts with customers during both periods. Such decrease was primarily driven by a decrease in 
realized crude oil price of 8%, partially offset by an increase in crude oil sales volumes of 7% year over year.  
Total volume of crude oil sold increased to 15.7 MMbbl during the year ended December 31, 2023, 
compared to 14.8 MMbbl during the year ended December 31, 2022, mainly driven by a 5% production growth year-
over-year, which in turn resulted from 31 shale oil wells tied-in during 2023, increasing the total number of shale 
wells on production to 99 at year-end. This activity boosted oil production, which increased 8% year-over-year during 
2023. On a pro forma basis, adjusted by the transfer of the conventional assets as of March 1, 2023, oil production 
grew 20% year-over-year during 2023. 
Average realized crude oil sales prices decreased to US$66.7/bbl during the year ended December 31, 2023, 
compared to US$72.3/bbl during the year ended December 31, 2022, a decrease that was mainly driven by a lower 
Brent crude oil price, which decreased 17% during 2023 compared to 2022, on average.  
In 2023, 8.2 MMbbl of crude oil, or 52% of total crude oil volumes, were sold to export markets for a total 
revenue of US$642.2 million, which, net of export duties of US$48.4 million, amounted to US$593.8 million. In 
2022, 6.6 MMbbl of crude oil, or 44% of total crude oil volumes, were sold to export markets for a total revenue of 
US$605.0 million, which, net of export duties of US$45.4 million, amounted to US$559.6 million. 
Revenues from natural gas decreased to US$67.3 million during the year ended December 31, 2023, 
compared to US$68.7 million during the year ended December 31, 2022, which represented 6% of our total revenue 
from contracts with customers during both periods. Such decrease was primarily driven by a decrease in the realized 
natural gas price, which decreased 13% during 2023 compared to 2022. 
Total volume of natural gas sold increased to 3.3 MMboe during the year ended December 31, 2023, 
compared to 3.0 MMboe during the year ended December 31, 2022.  
The average realized natural gas sales prices was US$3.5/MMBtu during the year ended December 31, 2023, 
a 13% decrease compared to US$4.0/MMBtu during the year ended December 31, 2022. Such decrease was mainly 
driven by lower prices to industrial customers at US$2.3/MMBtu during 2023, compared to US$3.7/MMBtu in 2022. 
Revenues from NGL decreased to US$4.2 million during the year ended December 31, 2023, compared to 
US$5.6 million during the year ended December 31, 2022, which represented less than 1% of our total revenue from 
contracts with customers during both periods.  

 
116 
 
During the year ended December 31, 2023, 99% of our revenue was generated by our oil and gas properties 
in Argentina, as well as during the year ended December 31, 2022.

Cost of sales increased to US$577.5 million during the year ended December 31, 2023, compared to 
US$557.4 million during the year ended December 31, 2022. Total cost of sales included operating costs, fluctuations 
in the inventory of crude oil, depreciation, depletion and amortization, royalties and others, and other non-cash costs 
related to the transfer of conventional assets.  
Operating costs decreased to US$94.7 million during the year ended December 31, 2023, compared to 
US$133.4 during the year ended December 31, 2022, which represented 16% and 24% of our total cost of sales, 
respectively. Operating costs per produced barrel decreased to US$5.1/boe during the year ended December 31, 2023, 
from US$7.5/boe during the year ended December 31, 2022. This decrease was primarily driven by the savings 
generated by the Conventional Assets Transaction to fully-focus on shale oil operations as of March 1, 2023, 
economies of scale driven by production volume growth, and focus on cost efficiency.  
The crude oil stock fluctuation increased to US$2.1 million during the year ended December 31, 2023, 
compared to US$0.5 million during the year ended December 31, 2022. This was primarily due to the decrease in 
crude oil stock at the end of the period. 
Depreciation, depletion and amortization increased to US$276.4 million during the year ended December 31, 
2023, compared to US$234.9 million during the year ended December 31, 2022, which represented 48% and 42% of 
our total cost of sales, respectively. This increase was primarily driven by higher capital expenditures and total 
production in 2023 compared to 2022. 
Royalties and others decreased to US$176.8 million during the year ended December 31, 2023, compared to 
US$188.7 million during the year ended December 31, 2022, which represented 31% and 34% of our total cost of 
sales, respectively. This decrease was primarily driven by the above-mentioned decrease in realized oil price and 
realized natural gas price.  
Other non-cash costs related to the transfer of conventional assets was US$27.5 million during the year 
ended December 31, 2023, which represented 5% of our total cost of sales during the period. These non-cash were 
mainly related to the Conventional Assets Transaction. 
Gross Profit  
Gross profit decreased to US$591.2 million during the year ended December 31, 2023, compared to 
US$630.2 million during the year ended December 31, 2022, which represented 51% and 53% of our total revenue 
from contracts with customers, respectively.  
Selling Expenses  
Selling expenses increased to US$68.8 million during the year ended December 31, 2023, compared to 
US$59.9 million during the year ended December 31, 2022, which represented 6% and 5% of our total revenue from 

 
117 
 
contracts with customers, respectively. This increase was primarily driven by an increase of 104% in Fees and 
compensation for services, and 15% in Transport, in both cases during 2023 compared to 2022. 
General and Administrative Expenses  
General and administrative expenses increased to US$70.5 million during the year ended December 31, 
2023, compared to US$63.8 million during the year ended December 31, 2022, which represented 6% and 5% of our 
total revenue from contracts with customers, respectively. This increase was primarily driven by a 40% increase in 
Share-based payments, a 39% increase in Employee Benefits and a 19% increase in Fees and compensation for 
services, in all cases during 2023 compared to 2022. 
Exploration Expenses  
Exploration expenses decreased to US$0.02 million during the year ended December 31, 2023, compared to 
US$0.7 million during the year ended December 31, 2022. 
Other Operating Income  
Other operating income increased to US$203.8 million during the year ended December 31, 2023, compared 
to US$26.7 million during the year ended December 31, 2022. This increase was mainly driven by the gains related to 
the Conventional Assets Transaction and the gains related to the repatriation of 27% of the export proceeds of the 
fourth quarter of 2023 at the bluechip swap exchange rate, as per applicable regulations. 
Other Operating Expenses  
Other operating expenses resulted in a gain of US$0.3 million during the year ended December 31, 2023, 
compared to a loss of US$3.3 million during the year ended December 31, 2022.  
Impairment of Long-Lived Assets 
Impairment of long-lived assets was US$24.6 million during the year ended December 31, 2023, mainly 
related to the concession CS-01 in Mexico, compared to null during the year ended December 31, 2022. 
Operating Profit  
Operating profit increased to US$631.5 million during the year ended December 31, 2023, compared to 
US$529.1 million during the year ended December 31, 2022, which represented 54% and 45% of our total revenue 
from contracts with customers, respectively.  
Interest Income  
Interest income increased to US$1.2 million during the year ended December 31, 2023, compared to US$0.8 
million during the year ended December 31, 2022.  
Interest Expense  
As of December 31, 2023, the interest expense decreased to US$21.9 million from US$28.9 million for the 
year ended December 31, 2022. This decrease was primarily due to new debt issuances at a lower interest rate.  
Other Financial Results  
Other financial results totaled a loss of US$65.5 million for the year ended December 31, 2023, compared to 
a loss of US$67.6 million for the year ended December 31, 2022. This change was primarily due to a 183% decrease 
in the discount of assets and liabilities at present value, a 210% decrease in changes in the fair value of financial 

 
118 
 
assets and a 45% in net changes in foreign exchange rate, partially offset by a 36% increase in revaluations of loans 
originated by financial liabilities incurred in Argentina adjusted by the UVA.   
Profit Before Income Taxes  
Profit before income taxes totaled a gain of US$545.4 million during the year ended December 31, 2023, 
compared to a loss of US$433.5 million during the year ended December 31, 2022.  
Income Tax expense  
Our income tax expenses totaled a loss of US$148.4 million during the year ended December 31, 2023, 
compared to a loss of US$164.0 million during the year ended December 31, 2022. This change was primarily driven 
by a net effect of (i) an decrease in current income tax expenses from US$92.1 million to US$16.4 million compared 
to the year ended December 31, 2022, and (ii) an increase in deferred income tax expense of US$132.0 million in 
2023, compared to US$71.9 million in 2022, mainly driven by the deferred tax inflation adjustment from our main 
subsidiary Vista Argentina, and the depreciation of the Argentine Peso with respect to the U.S. Dollar affecting the 
Company’s tax deductions of non-monetary assets.  
Profit for the year, net  
During the year ended December 31, 2023, the profit for the year, net totaled US$397.0 million, compared to 
US$269.5 million during year ended December 31, 2022.

ITEM 5.B  
LIQUIDITY AND CAPITAL RESOURCES 
Our financial condition and liquidity are and will continue to be influenced by a variety of factors, including:  
•  
 
• 
changes in oil, natural gas and liquid gas prices and our ability to generate cash flows from our 
operations;  
• 
our capital expenditure requirements; and  
• 
the level of our outstanding indebtedness and the interest we are obligated to pay on this indebtedness.  
On August 15, 2017, we completed our US$650 million initial global offering of 65,000,000 series A shares 
and 65,000,000 warrants exercisable for such series A shares (“Warrants”), generating net proceeds to us, after 
offering expenses, of US$640 million. The series A shares and warrants issued pursuant to our initial global offering 
are listed on the Mexican Stock Exchange.  
As of the date of this annual report, there are no outstanding warrants as a result of the automatic exercise of 
all outstanding warrants on a cashless basis. See “Item 10—Additional Information—Memorandum and Articles of 
Association—Warrants.” 
Concurrently with our initial global offering, Vista Sponsor Holdings, L.P. and the Executive Team 
purchased a total of 29,680,000 warrants exercisable for series A shares in a private placement (“Sponsor Warrants”), 
generating gross proceeds to us of US$14,840,000. The Sponsor Warrants were identical to and fungible with the 
Warrants. As of the date of this annual report, there are no outstanding Sponsor Warrants as a result of the automatic 
exercise of all outstanding warrants on a cashless basis. See “Item 10—Additional Information—Memorandum and 
Articles of Association—Warrants.” 
On April 4, 2018, the date we consummated our acquisition of certain assets from Pampa Energia S.A. and 
Pluspetrol Resources Corporation:  
• 
we entered into a bridge loan agreement (“Bridge Loan”) with Citibank, N.A., Credit Suisse AG 
Cayman Islands Branch and Morgan Stanley Senior Funding, Inc. in an aggregate principal amount 
equal to US$260.0 million, maturing on February 11, 2019, bearing interest at a variable rate 
between 3.25% and 5%. The Bridge Loan was prepaid in full on or about July 19, 2018 with the 
proceeds of the Credit Agreement.  
 
• 
approximately 31.29% of holders of series A shares exercised their redemption rights, as a result of 
which 20,340,685 series A shares were redeemed for an amount of US$204.6 million. The holders 
of remaining series A shares were capitalized net of the deferred offering expenses paid to the 
underwriters in our initial global offering for an amount of US$442.5 million, and  
• 
we obtained from a private placement transaction a capital contribution of US$95,000,000 
representing 9,500,000 series A shares that were paid in.  
For more information on this acquisition, please see “Presentation of Information─The Initial Business 
Combination” in Vista’s annual report on Form 20-F filed with the SEC on April 30, 2020. 
In July 2019, we completed a global offering consisting of a follow-on public offering in Mexico of our 
series A shares and an international public offering in the United States and other countries of our series A shares 
represented by American Depositary Shares on the NYSE for a total amount of 10,906,257 series A shares (including 
all over-allotment options). Our ADSs began trading on the NYSE on July 26, 2019, under the ticker symbol “VIST.” 
The gross proceeds of the global offering amounted to approximately US$101 million, before fees and expenses. 
As of the date of this annual report, 3,215,454 shares became outstanding as the Warrants in their original 
terms have been exercised in full.  See “Item 10—Additional Information—Memorandum and Articles of 
Association—Warrants.” 
We believe that our working capital is sufficient for our present requirements.

Capital Expenditures 
The amount and allocation of future capital expenditures will depend upon a number of factors, including 
our cash flows from operating, investing and financing activities and our ability to execute our drilling program. We 
periodically review our capital expenditure budget to assess changes in current and projected cash flows, debt 
requirements and other factors. If we are unable to obtain funds when needed or on acceptable terms, we may not be 
able to finance the capital expenditures necessary to maintain our production or proved reserves. We intend to fund 
our capital expenditures with cash generated from our operations, cash on hand, and debt and equity financing. 
Because we operate a high percentage of our acreage, capital expenditure amounts (in addition to our capital 
expenditures committed under our concessions) and timing are largely discretionary and within our control. We 
determine our capital expenditures depending on a variety of factors, including, but not limited to, existing 
commitments under the concessions, the success of our drilling activities, prevailing and anticipated prices for oil and 
natural gas, the availability of necessary equipment, infrastructure and capital, the receipt and timing of required 
regulatory permits and approvals, seasonal conditions, drilling and acquisition costs and the level of participation by 
other working interest owners. A deferral of planned capital expenditures, particularly with respect to drilling and 
completing new wells, could result in a reduction in anticipated production and cash flows. Moreover, we may be 
required to unbook some portion of our current proved undeveloped reserves if such deferral of planned capital 
expenditures implies that we will be unable to develop such reserves within five years of their initial booking.  
During the year ended December 31, 2024, we made total capital expenditures of US$1,296.8 million. 
During the year ended December 31, 2023, we made total capital expenditures of US$734.3 million. During the year 
ended December 31, 2022, we made total capital expenditures of US$540.0 million.  
As part of the terms and conditions governing the concession agreements relating to our oil and gas 
properties in Argentina, we are committed to making capital investments for drilling and completing wells, 
performing well workovers and investing in facilities. We have estimated the amount of capital expenditures required 
to comply with our commitments under such concessions based on the historical costs of drilling and completing 
wells, performing well workovers and investing in facilities.  
 
According to our best estimates, as of the date of this annual report, our remaining investment commitments 
include drilling and completing nine development wells, executing 44 workovers, and abandoning 21 wells in Entre 
Lomas, 25 de Mayo–Medanito SE, and Jagüel de los Machos. 
 
Pursuant to the Conventional Assets Transaction agreement, Aconcagua has assumed all past investment 
commitments, along with the associated costs, taxes, and royalties related to the CAT Exploitation Concessions. 
 
Capital expenditures related to these commitments amount to an estimated US$40 million. For more 
information on these investment commitments, see Note 29 to our Audited Financial Statements.

TREND INFORMATION 
See “Item 4—Information on the Company—Industry and Regulatory Overview.” 
In addition to the information set forth in this section, additional information about the trends affecting our 
business can be found in “Item 3—Key Information—Risk Factors—Detailed Risk Factors—Risks Related to Our 
Business and Industry.” You should also read our discussion of the risks and uncertainties that affect our business in 
“Item 3—Key Information—Risk Factors—Detailed Risk Factors—Risks Related to the Argentine and Mexican 
Economic and Regulatory Environments.” 
ITEM 5.E 
CRITICAL ACCOUNTING ESTIMATES 
Critical accounting policies are policies that require us to exercise judgment or involve a higher degree of 
complexity in the application of the accounting policies that currently affect our financial condition and results of 
operations. The accounting judgments and estimates we make in these contexts require us to calculate variables and 
make assumptions about matters that are highly uncertain. In each case, if we had made other estimates, or if changes 
in the estimates occur from period to period, our financial condition and results of operations could be materially 
affected. 
See Note 3 to our audited financial statements for a summary of the critical accounting judgments and 
estimates applicable to us. There are many other areas in which we use estimates about uncertain matters, but we 
believe the reasonably likely effect of changes or differences within critical accounting judgments and estimates 
would not have a material impact on our financial statements. 
ITEM 6. 
DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES 
Board of Directors  
Under the Mexican Securities Market Law, public companies must have a board of directors comprised of no 
more than 21 members, of which at least 25% must be independent. Independent members must be selected based on 
their experience, ability and reputation at the issuer’s shareholders’ meeting; whether or not a director is independent 
must be determined by the issuer’s shareholders and such determination may be challenged by the CNBV. The 
Mexican Securities Market Law permits then-acting members of the board of directors (as opposed to shareholders) to 
select, under certain circumstances and on a temporary basis, new members of the board of directors.  
Boards of directors of public companies are required to meet at least four times during each calendar year 
and have the following principal duties:  
• 
determine general strategies applicable to the issuer;  
• 
approve guidelines for the use of corporate assets;  

 
124 
 
• 
approve, on an individual basis, transactions with related parties, subject to certain limited 
exceptions;  
• 
approve unusual or exceptional transactions and any transactions that imply the acquisition or sale

Duties and Liabilities of Directors 
The Mexican Securities Market Law also imposes duties of care and loyalty on directors.  
The duty of care generally requires that directors obtain sufficient information and be sufficiently prepared to 
support their decisions and to act in the best interest of the issuer. The duty of care is discharged, principally, by 
requesting and obtaining from the issuer and its officers all the information required to participate in discussions, 
obtaining information from third parties, attending board meetings and disclosing material information in possession 
of the relevant director. Failure to act with care by one or more directors subjects the relevant directors to joint 
liability with the other directors involved in an action for damages and losses caused to the issuer and its subsidiaries, 
which may be limited (except in the instances of bad faith, or illegal acts or willful misconduct) under the company’s 
bylaws or by resolution of a shareholders’ meeting. Liability for a breach of the duty of care may also be covered by 
indemnification provisions and director and officer liability insurance policies.  
The duty of loyalty primarily consists of a duty to maintain the confidentiality of information received in 
connection with the performance of a director’s duties and to abstain from discussing or voting on matters where the 
director has a conflict of interest. In addition, the duty of loyalty is breached if a shareholder or group of shareholders 
is knowingly favored or if, without the express approval of the board of directors, a director takes advantage of a 
corporate opportunity. The duty of loyalty is also breached if a shareholder or group of shareholders is knowingly 
favored, if the director discloses false or misleading information or fails to register any transaction in the issuer’s 
records that could affect its financial statements or causes material information not to be disclosed or to be modified. 
The duty of loyalty is also breached if the director uses corporate assets or approves the use of corporate assets in 
violation of an issuer’s policies. The violation of the duty of loyalty subjects the offending director to joint liability 
for damages and losses caused to the issuer and its subsidiaries. Liability also arises if damages and losses result from 
benefits obtained by the directors or third parties, as a result of activities carried out by the directors. Liability for 
breach of the duty of loyalty may not be limited by the company’s bylaws, by resolution of a shareholders’ meeting or 
otherwise.  
Claims for breach of the duty of care or the duty of loyalty may be brought solely for the benefit of the issuer 
(as a derivative suit) and may only be brought by the issuer or by shareholders representing at least 5% of any 
outstanding shares.  
As a safe-harbor for directors, the liabilities specified above will not be applicable if the director acted in 
good faith and (i) complies with applicable law and the bylaws, (ii) acted based upon information provided by 
officers, external auditors or third-party experts, the capacity and credibility of which may not be the subject of 
reasonable doubt, (iii) selected the more adequate alternative in good faith or in a case where the negative effects of 
such decision may not have been foreseeable, based upon the then available information, and (iv) actions were taken 
in compliance with resolutions adopted at the shareholders’ meeting.  
Under the Mexican Securities Market Law, the issuer’s chief executive officer and principal executives are 
also required to act for the benefit of the company and not of a shareholder or group of shareholders. Principally, 
these executives are required to submit to the board of directors for approval the principal strategies for the business, 
to submit to the audit committee proposals relating to internal control systems, to disclose all material information to 
the public and to maintain adequate accounting and registration systems and internal control mechanisms.

Actions by our Executive Team  
Our Chief Executive Officer and the other relevant officers (including members of our Executive Team) are 
required under the Mexican Securities Market Law to focus their activities on maximizing shareholder value in our 
Company. Our Chief Executive Officer and senior management may be held liable for damages to us, our subsidiaries 
and others for the following: (i) favoring a single group of shareholders, (ii) approving transactions between us, or our 
subsidiaries, with related persons without complying with applicable legal requirements, (iii) taking advantage of our 
subsidiaries’ assets for their own personal gain contrary to Company policy (or authorizing a third-party to do so on 
their behalf), (iv) making inappropriate use of our, or our subsidiaries’ non-public information or (v) knowingly 
disclosing or revealing false or misleading information.  
Our Chief Executive Officer and the other relevant officers (including members of our Executive Team) are 
required under the Mexican Securities Market Law to act for the benefit of our Company and not that of a particular 
shareholder or group of shareholders. Our Chief Executive Officer is also required to (i) implement the instructions of 
our shareholders (as delivered during a shareholders’ meeting) and our board of directors, (ii) submit to our board of 
directors for approval the principal strategies for the business, (iii) submit to the audit and corporate practices

the same fiduciary duty obligations as our directors.  
Our executive team also plays an important role from an ESG perspective. During 2022, we redefined our 
internal ESG framework with annual and mid-term objectives. Each of our senior managers is the project leader for 
one or more initiatives in our ESG framework. Each initiative has objectives, which are executed as projects, by each 
team and a project leader, who is responsible for moving each initiative forward. On a quarterly basis, the project 
leaders present the progress of their work program to the Executive Team and the Corporate Practices Committee, 
which in turn presents key aspects and conclusions to the Board of Directors. 
Family Relationships

Employees  
As of December 31, 2024, we had 528 employees, of which 510 were in Argentina and 18 in Mexico.

As of December 31, 2024, December 31, 2023, and December 31, 2022, 55%, 54% and 59%, respectively, of 
our employees in Argentina were represented by one union and benefitted from a collective bargaining agreement 
between such union and our subsidiaries.  
Since 2017, we have not experienced any material labor-related problems or major labor disturbances, and 
our relations with the unions are stable. However, we cannot guarantee that we will not experience any conflicts with 
our employees in the future, including with our unionized employees in the context of future negotiations of our 
collective bargaining agreements, which could result in events such as strikes or other disruptions that could have a 
negative impact on our operations. For further information on risk of labor disputes, see “Item 3—Key Information—
Risk Factors—Detailed Risk Factors—Risks Related to our Company—We employ a highly unionized workforce and 
could be subject to labor actions such as strikes, which could have a material adverse effect on our business.” 
As of December 31, 2024, there were also approximately 700 outsourced staff that access our operations on 
a daily basis to provide services. Although we have policies regarding compliance with labor and social security 
obligations for our contractors, we can provide no assurance that the contractors’ employees will not initiate legal 
actions against us seeking indemnification based upon a number of Argentine judicial labor court precedents that 
established that the ultimate beneficiary of employee services is joint and severally liable with the contractor, which is 
the employee’s formal employer. See “Item 3—Key Information—Risk Factors—Detailed Risk Factors—Risks 
Related to our Company—We face risks related to certain legal proceedings.”  
We are firmly committed to providing the necessary tools for our workforce to grow technically and advance 
their careers within the Company. We have designed a professional development plan for technical training: the 
technical career program. First, we identified a matrix of critical competencies needed for the different technical 
positions. We conduct a gap analysis of our workforce and identify the skills needed to improve the qualification of 
our teams. Each career has a technical mentor and a person who evaluates the progress of individuals at each step of 
their career. We believe Vista has exceptional and experienced mentors who come from technical backgrounds and 
have been specifically involved with Vaca Muerta since the beginning of development.

MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS 
ITEM 7.A 
MAJOR SHAREHOLDERS 
Our outstanding capital stock consists of two series of shares: series A shares and series C shares, in each 
case registered with the RNV and listed on the Mexican Stock Exchange. As of December 31, 2024, our capital stock 
was represented by 95,285,451 series A shares, and two series C shares. As of the date of this annual report, our 
capital stock was represented by 98,150,716 series A shares, and two series C shares. Each series of shares grants the 
same rights and obligations to its holders, including corporate and economic rights.  
The following table sets forth certain information known to us of our shareholders who are beneficial owners 
of more than 5% of our series A shares and series C shares as of the date of this annual report (except as set forth 
below), which is the most recent practicable date as to which we have information available. In computing the number 
of series A shares beneficially owned by a person or entity and the percentage ownership of that person or entity, we 
deemed to be outstanding all series A shares subject to stock options or restricted stock held by that person or entity 
that are currently exercisable or that will become exercisable or vested, as applicable, within 60 days of the date of 
this annual report. series A shares issuable pursuant to stock options or restricted stock are deemed outstanding for 
computing the percentage ownership of the person or entity holding such options but are not outstanding for 
computing the percentage of any other person or entity.

See Item 18 for our Audited Financial Statements. For a description of events that have occurred since the date of the 
Company’s Financial Statements, see “Item 4—Information on the Company—Recent Developments.” 
LEGAL PROCEEDINGS 
From time to time, we may be subject to various lawsuits, claims and proceedings that arise in the normal 
course of business, including employment, commercial, environmental, safety and health matters. For example, from 
time to time, we receive notice from regulatory authorities in connection with the fulfillment of certain environmental, 
health and/or safety matters. It is not presently possible to determine whether any such matters will have a material 
adverse effect on our consolidated financial position, results of operations or liquidity.  
For more information on the legal proceedings see Notes 22.3 and 28 to the Audited Financial Statements. 
DIVIDENDS 
Under Mexican law, subject to the satisfaction of certain quorum requirements, only shareholders at a 
general meeting have the authority to declare a dividend. Although not required by law, such declarations typically 
follow the recommendation of the Board of Directors. Additionally, under Mexican law, we may only pay dividends 
from retained earnings included in financial statements that have been approved at a general shareholders’ meeting, 
after all losses from prior fiscal years have been satisfied and after at least 5% of net income (after profit sharing and 
other deductions required by Mexican law) has been allocated to legal reserves, up to an amount equal to 20% of our 
paid-in capital stock from time to time. We have paid no dividend since our incorporation.  
Our Board of Directors is not currently considering the adoption of a dividend policy. Changes in our 
operating and financial results, including those derived from extraordinary events, and risks described in “Risk 
Factors” that affect our financial condition and liquidity, could limit any distribution of dividends and their amount. 
We cannot provide any assurances that we will pay dividends in the future or as to the amount of dividends, if any are 
paid.  
The amount and payment of future dividends, if any, will be subject to applicable law and will depend upon 
a variety of factors that may be considered by our Board of Directors or our shareholders, including our future 
operating results, financial condition, capital requirements, investments in potential acquisitions or other growth 
opportunities, legal restrictions, contractual restrictions in our current and future debt instruments and our ability to 
obtain funds from our subsidiaries. Such factors may limit or prevent the payment of any future dividends and may be 

 
135 
 
considered by our Board of Directors in recommending, or by our shareholders in approving, the payment of any 
future dividends.  
We are a holding company and our income, and therefore our ability to pay dividends, is dependent upon the 
dividends and other distributions that we receive from our subsidiaries. The payment of dividends or other 
distributions by our subsidiaries will depend upon their operating results, financial condition, capital expenditures 
plans and other factors that their respective boards of directors deem relevant. Dividends may only be paid out of 
distributable reserves and our subsidiaries are required to allocate earnings to their respective legal reserve funds prior 
to paying dividends to us. In addition, covenants in loan agreements, if any, of our subsidiaries, may limit their ability 
to declare or pay cash dividends.  
In the event we were to declare dividends they would be paid in Mexican Pesos through Indeval to each 
custodian, which would deduct any applicable withholding taxes. In the case of series A shares represented by ADSs, 
the depositary will convert the cash dividends it receives in Mexican Pesos into U.S. Dollars at the prevailing rate of 
exchange, and thereafter it would distribute the amount so converted to the holders of ADSs, net of conversion 
expenses of the depositary. Fluctuations in the Mexican Peso—U.S. Dollar exchange rate will affect the amount of 
dividends that ADS holders would receive.  
Dividends paid from our distributable earnings that have not been subject to corporate income tax (i.e., that 
do not derive from our net after-tax profits account (cuenta de utilidad fiscal neta or “CUFIN”) are subject to a 
corporate-level tax payable by us. We are entitled to apply any such tax on the distribution of earnings as a credit 
against our Mexican corporate income tax corresponding to the fiscal year in which the dividend was paid or against 
the Mexican corporate income tax of the two fiscal years following the date in which the dividend was paid. 
Dividends paid from our distributable earnings that have been subject to corporate income tax (i.e., that derive from 
the company’s CUFIN balance) are not subject to this corporate-level dividend income tax. 
On March 16, 2022, the Board of Directors of the Company called for an Ordinary and Extraordinary 
General Shareholders’ meeting, to propose, discuss, and, if applicable, approve a proposal permitting up to US$23.84 
million (namely the total net profits for the year 2021, including the retained profits (accumulated results) minus 
US$1.26 million, that will be set aside to constitute the legal reserve) to be used for the purchase of the Company’s 
own shares during 2022. If the maximum amount of funds set aside for the purchase are not entirely used by 
December 31, 2022, the Company may use the remaining amount to repurchase its own shares during 2023. The 
amount of funds applicable to be used in 2023 may be increased or modified by any subsequent shareholders’ 
meeting. The proposal was subsequently approved by the Ordinary and Extraordinary General Shareholders’ meeting 
on April 26, 2022. 
On October 26, 2022, the Board of Directors of the Company called for an Ordinary General Shareholders’ 
meeting, to propose, discuss, and, if applicable, approve a proposal permitting up to US$25.63 million (namely the 
total net profits for the first nine months of 2022, including the retained profits (accumulated results) minus US$1.35 
million, that will be set aside to constitute the legal reserve) to be used for the purchase of the Company’s own shares 
during 2022. If the maximum amount of funds set aside for the purchase are not entirely used by December 31, 2022, 
the Company may use the remaining amount to repurchase its own shares during 2023. The amount of funds 
applicable to be used in 2023 may be increased or modified by any subsequent shareholders’ meeting. The proposal 
was subsequently approved by the Ordinary General Shareholders’ meeting on December 7, 2022. 
On April 24, 2023, the Shareholder’s Meeting approved an amendment of the maximum amount of funds 
that may be used for the purchase of the Company’s shares (or securities representing such shares) for the fiscal year 
ended December 31, 2023, from the originally approved US$20.1 million to US$50.0 million, the remainder of 
which, if any, may be used for the same purposes for the fiscal year ended December 31, 2024. 
On August 6, 2024, the Shareholder’s Meeting approved the maximum amount of funds that may be used for 
the purchase of the Company’s shares (or securities representing such shares) for the fiscal year ended December 31, 
2024, for US$50.0 million, the remainder of which, if any, may be used for the same purposes for the fiscal year 
ended December 31, 2025.

ITEM 9. 
THE OFFER AND LISTING 
TRADING HISTORY 
Our capital stock is comprised of common shares, no par value. Each share entitles the holder thereof to one 
vote at shareholders’ meetings. All outstanding shares are fully paid in and our common shares have been listed on the 
BMV since 2017. Since July 26, 2019, our ADSs have been listed on the NYSE. The ADSs have been issued by the 
Bank of New York as depositary. Each ADS represents one common share. 
MARKET INFORMATION 
Market of Our Shares 
Our ADSs are currently listed on the NYSE under the symbol “VIST.” Each ADS issued by the Depositary 
represents rights to one series A share. Our series A shares are listed on the Mexican Stock Exchange under the 
symbol “VISTA.” As of December 31, 2024, the variable portion of our outstanding capital stock was comprised by 
95,285,451 series A shares, registered with the RNV and listed on the Mexican Stock Exchange. The variable portion 
of our capital stock is of unlimited amount pursuant to our bylaws and the applicable laws, whereas the fixed portion 
of our capital stock is divided into two series C shares, registered with the RNV and listed on the Mexican Stock 
Exchange.  
Trading on the Mexican Stock Exchange  
The Mexican Stock Exchange, located in Mexico City, is one of two stock exchanges currently operating in 
Mexico. Operating continuously since 1907, the Mexican Stock Exchange is organized as a variable capital public 
stock corporation (sociedad anónima bursátil de capital variable). Securities trading on the Mexican Stock Exchange 
occurs each business day from 8:30 a.m. to 3:00 p.m. Mexico City time, subject to adjustments to operate uniformly 
with certain markets in the United States.  
Since January 1999, all trading on the Mexican Stock Exchange has been affected electronically. The 
Mexican Stock Exchange may impose a number of measures to promote an orderly and transparent trading price of 
securities, including the operation of a system of automatic suspension of trading in shares of a particular issuer, when 
price fluctuations exceed certain limits.  
Settlement of transactions with equity securities on the Mexican Stock Exchange are affected three business 
days after a share transaction is agreed to. Deferred settlement is not permitted without the approval of the Mexican 
Stock Exchange, even where mutually agreed. Securities traded on the Mexican Stock Exchange are on deposit in 
book-entry form through the facilities of Indeval, a privately owned securities depositary that acts as a clearinghouse, 
depositary, and custodian, as well as a settlement, transfer, and registration agent for Mexican Stock Exchange 
transactions, eliminating the need for physical transfer of securities. Transactions must be settled in Mexican Pesos 
except under limited circumstances and in respect of limited transactions in which settlement in foreign currencies 
may be permitted.  
Market Regulation  
In 1924, the CNBV was established to regulate banking activity and in 1946, the Mexican Securities 
Commission was established to regulate securities market activity. In 1995, these two entities merged to form the 
CNBV.  
Among other things, the CNBV regulates the public offering and trading of securities, public companies and 
participants in the Mexican securities market (including brokerage houses and the Mexican Stock Exchange), and 
imposes sanctions for the illegal use of insider information and other violations of the Mexican Securities Market 
Law. The CNBV regulates the Mexican securities market, the Mexican Stock Exchange, and brokerage firms, through 
its staff and a board of governors composed of thirteen members.  

 
137 
 
Mexican Securities Market Law  
The current Mexican Securities Market Law (as amended from time to time) was published in the Mexican 
Federal Official Gazette on December 30, 2005, and became effective on June 28, 2006, and is referred to as the 
Mexican Securities Market Law.  
In particular, the Mexican Securities Market Law:  
• 
includes private placement exemptions directed to Mexican institutional and qualified investors, and 
specifies the requirements that need to be satisfied for an issuer or underwriter to fall within the 
exemption; 
• 
includes improved rules for tender offers, dividing them in either voluntary or mandatory;  
• 
establishes standards for disclosure of holdings applicable to shareholders of public companies;  
• 
establishes the role of the board of directors of public companies;  
• 
defines the role of the chief executive officer and other relevant officers of public corporations;  
• 
defines the standards applicable to the board of directors and the duties and potential liabilities and 
penalties applicable to each director, the chief executive officer and other executive officers and the 
audit and corporate governance committee (introducing concepts such as the duty of care, duty of 
loyalty and safe harbors for actions attributable to directors and officers);  
• 
establishes the audit and corporate governance committee and establishes the audit and corporate 
governance committee with clearly defined responsibilities;  
• 
sets forth rights of minority shareholders (including the right to initiate shareholders’ derivative 
suits);  
• 
defines applicable sanctions for violation of law;  
• 
provides flexibility to allow regulated Mexican brokerage firms to engage in certain limited 
activities;  
• 
regulates stock exchanges, clearinghouses, futures and derivatives markets, and rating agencies;  
• 
establishes penalties (including incarceration), arising from violations of the Mexican Securities 
Market Law and regulations thereunder;  
• 
establishes that public companies are considered a single economic unit with the entities they 
control for reporting accounting and other purposes;  
• 
establishes concepts such as consortiums, groups of related persons or entities, control and decision-
making power;  
• 
defines rules relating to the types of securities that may be offered by public companies;  
• 
sets forth information for share repurchases; and  
• 
specifies requirements for implementing anti-takeover measures.  
In March 2003, the CNBV issued certain general regulations applicable to issuers and other securities market 
participants, which regulations have since been amended, or the General Regulations, and in September 2004, the 
CNBV issued certain general regulations applicable to brokerage firms. The General Regulations, which repealed 
several previously enacted CNBV regulations, provide a consolidated set of rules governing public offerings, 
reporting requirements and issuer activity, among other things.  
More recently, a decree amending certain provisions on the Mexican Securities Market Law became 
effective on December 29, 2023, which contains, among others, certain provisions and adjustments (a) providing 
flexibility to issue different series and classes of shares without requiring CNBV authorization and without a 
percentage limit, including shares without voting rights, with restricted voting rights, with veto rights, that limit or 
expand the distribution of profits or other special economic rights; and (b) allowing to delegate to the board of 
directors of public companies the authority to approve capital increases and determine the terms for the subscription 

 
138 
 
of shares issued in connection with such increase, including restrictions on the exercise of preemptive subscription 
rights. 
Issuance, Registration and Listing Standards  
In order to offer securities to the public in Mexico, an issuer must meet specific qualitative and quantitative 
requirements. Only securities that have been registered with the RNV, pursuant to approval by the CNBV may be 
listed on the Mexican Stock Exchange.  
The General Regulations require the Mexican Stock Exchange to adopt minimum requirements for issuers 
that seek to list their securities in Mexico. These requirements relate to operating history, financial and capital 
structure, and minimum public floats, among other things. The General Regulations also require the Mexican Stock 
Exchange to implement minimum requirements (including minimum public floats) for issuers to maintain their listing 
in Mexico. These requirements relate to the issuer’s financial condition, capital structure and public float, among 
others. The CNBV may waive some of these requirements in certain circumstances. In addition, some of the 
requirements are applicable for each series of shares of the relevant issuer.  
The CNBV’s approval for registration with the RNV does not imply any kind of certification or assurance 
related to the investment quality of the securities, the solvency of the issuer, or the accuracy or completeness of any 
information delivered to the CNBV or included in any offering document.  
The Mexican Stock Exchange may review compliance with the foregoing requirements and other 
requirements at any time, but will normally do so on an annual, semi-annual and quarterly basis. The Mexican Stock 
Exchange must inform the CNBV of the results of its review, and this information must, in turn, be disclosed to 
investors. If an issuer fails to comply with any of these minimum requirements, the Mexican Stock Exchange will 
request that the issuer propose a plan to cure the violation. If the issuer fails to propose a plan, if the plan is not 
satisfactory to the Mexican Stock Exchange, or if an issuer does not make substantial progress with respect to the 
implementation of the corrective plan, trading of the relevant series of shares on the Mexican Stock Exchange may be 
temporarily suspended. In addition, if an issuer fails to implement the plan in full, the CNBV may cancel the 
registration of the shares, in which case the majority shareholder or any controlling group will be required to carry out 
a tender offer to acquire all of the outstanding shares of the issuer in accordance with the tender offer provisions set 
forth in the Mexican Securities Market Law (under which all holders must be treated in the same manner).  
Reporting Obligations  
Issuers of listed shares such as the Company, are required to file unaudited quarterly financial statements and 
audited annual financial statements (together with an explanation thereof) and periodic reports, in particular reports 
dealing with material events, with the CNBV and the Mexican Stock Exchange. Mexican issuers must file the 
following reports:  
• 
a comprehensive annual report prepared in accordance with the General Regulations, by no later 
than April 30 of each year, which must include (i) audited annual financial statements and 
(ii) reports on the activities carried out by the audit and corporate governance committee;  
• 
quarterly reports, within 20 business days following the end of each of the first three quarters and 
40 business days following the end of the fourth quarter;  
• 
reports disclosing material information;  
• 
reports and disclosure memoranda revealing corporate restructurings such as mergers, spin-offs or 
acquisitions or sales of assets, approved by shareholders’ meeting or the board of directors;  
• 
reports regarding the policies and guidelines with respect to the use of the company’s (or its 
subsidiaries) assets by related persons; and  
• 
details dealing with agreements among shareholders.  
Pursuant to the General Regulations, the internal rules of the Mexican Stock Exchange were amended to 
implement an automated electronic information transfer system (Sistema Electrónico de Envío y Difusión de 

 
139 
 
Información, or SEDI) called the Sistema Electrónico de Comunicación con Emisoras de Valores, or EMISNET, for 
information required to be filed with the Mexican Stock Exchange. Issuers of listed securities must prepare and 
disclose their financial and other information via EMISNET. Immediately upon receipt, the Mexican Stock Exchange 
makes this financial and other information available to the public.  
The General Regulations and the rules of the Mexican Stock Exchange require issuers of listed securities to 
file through SEDI information that relates to any event or circumstance that could influence an issuer’s share prices 
and investor decisions to acquire stock. If listed securities experience unusual price volatility, the Mexican Stock 
Exchange must immediately request that an issuer inform the public as to the causes of the volatility or, if the issuer is 
unaware of the causes, that it makes a statement to the effect that it is unaware of the causes of such volatility. In 
addition, the Mexican Stock Exchange must immediately request that issuers disclose any information relating to 
material events when it deems the available public information to be insufficient, as well as instruct issuers to clarify 
information when necessary. The Mexican Stock Exchange may request that issuers confirm or deny any material 
event that has been disclosed to the public by third parties when it deems that the material event may affect or 
influence the price of the listed securities. The Mexican Stock Exchange must immediately inform the CNBV of any 
such request. In addition, the CNBV may also make any of these requests directly to issuers. An issuer may delay the 
disclosure of material events if:  
• 
the information is related to transactions that have not been consummated;  
• 
there is no public information in the mass media relating to the material event; and  
• 
no unusual price or volume fluctuation occurs.  
If an issuer elects to delay the disclosure of material, it must implement adequate confidentiality measures 
(including maintaining a log with the names of parties in possession of confidential information and the date when 
each such party became aware of the relevant information).  
Similarly, if an issuer’s securities are traded on both the Mexican Stock Exchange and a foreign securities 
exchange, the issuer must simultaneously file the information that it is required to file pursuant to the laws and 
regulations of the foreign jurisdiction with the CNBV and the Mexican Stock Exchange.  
Suspension of Trading  
In addition to the authority of the Mexican Stock Exchange under its internal regulations described above, 
the CNBV and the Mexican Stock Exchange may suspend trading in an issuer’s securities:  
• 
if the issuer does not disclose a material event;  
• 
failure by the issuer to timely or adequately comply with its reporting obligations;  
• 
significant exceptions or comments contained in the auditors’ opinions of the issuer’s financial 
statements, or determinations that such financial statements were not prepared in accordance with 
the applicable accounting procedures and policies; or  
• 
upon price or volume volatility or changes in the trading of the relevant securities that are not 
consistent with the historic performance of the securities and cannot be explained solely through 
information made publicly available pursuant to the General Regulations.  
The Mexican Stock Exchange must immediately inform the CNBV and the general public of any suspension. 
An issuer may request that the CNBV or the Mexican Stock Exchange permit trading to resume if it demonstrates that 
the causes triggering the suspension have been resolved and that it is in full compliance with periodic reporting 
requirements. If an issuer’s request has been granted, the Mexican Stock Exchange will determine the appropriate 
mechanism to resume trading (which may include a bidding process to determine applicable prices). If trading in an 
issuer’s securities is suspended for more than 20 business days and the issuer is authorized to resume trading without 
conducting a public offering, the issuer must disclose via SEDI, before trading may resume, a description of the 
causes that resulted in the suspension.  

 
140 
 
Under consent regulations, the Mexican Stock Exchange may consider the measures adopted by other non- 
Mexican exchanges to suspend and/or resume trading of an issuer’s shares, in cases where the relevant securities are 
simultaneously traded on stock exchanges located outside of Mexico.  
Insider Trading, Trading Restrictions and Tender Offers  
The Mexican Securities Market Law contains specific regulations regarding insider trading, including the 
requirement that persons in possession of information deemed privileged abstain (i) from directly or indirectly, 
trading in the relevant issuer’s securities, or derivatives with respect to such securities, the trading price of which may 
be affected by such information, (ii) from making recommendations or providing advice to third parties to trade in 
such securities, and (iii) disclosing or communicating such privileged information to third parties (except for persons 
to whom such information must be disclosed as a result of their positions or employment).  
 
 
Pursuant to the Mexican Securities Market Law, the following persons must notify the CNBV of any 
transactions undertaken by them with respect to a listed issuer’s securities, whether on a case-by-case basis or 
quarterly:  
• 
members of a listed issuer’s board of directors;  
• 
shareholders directly or indirectly controlling 10% or more of a listed issuer’s outstanding capital 
stock; and  
• 
officers.  
These persons must also inform the CNBV of the effect of the transactions within five days following their 
completion. In addition, insiders must abstain from purchasing or selling securities of the issuer within three months 
from the last sale or purchase, respectively.  
Also, directors and relevant officers that are holders of 1% or more of the outstanding shares of a Mexican 
public company, must disclose their holdings and the relevant issuer.  
Subject to certain exceptions, any acquisition of a public company’s shares that results in the acquirer 
owning 10% or more, but less than 30%, of an issuer’s outstanding capital stock, must be publicly disclosed to the 
CNBV and the Mexican Stock Exchange by no later than one business day following the acquisition.  
Any acquisition or disposition by certain insiders that results in such insider increasing or decreasing in 5% 
or more such insider’s holdings in shares of the public company to which it is related must also be publicly disclosed 
to the CNBV and the Mexican Stock Exchange no later than one business day following the acquisition or 
disposition. The Mexican Securities Market Law requires that convertible securities, warrants and derivatives to be 
settled in kind be considered in the calculation of share ownership percentages of public companies.  
Tender Offers  
The Mexican Securities Market Law contains provisions relating to public tender offers and certain other 
share acquisitions occurring in Mexico. Under the Mexican Securities Market Law, tender offers may be voluntary or 
mandatory. Both are subject to prior approval of the CNBV and must comply with general legal and regulatory 
requirements. Voluntary tender offers, or offers where there is no requirement that they be initiated or completed, are 
required to be made pro rata. Any intended acquisition of a public company’s shares that results in the acquirer 
owning 30% or more requires the acquirer to make a mandatory tender offer for the greater of (i) the percentage of the 
capital stock intended to be acquired, or (ii) 10% of the company’s outstanding capital stock, provided that if such 
acquisition is aimed at obtaining control, then the potential acquirer is required to launch a mandatory tender offer for 
100% of the company’s outstanding capital stock (however, under certain circumstances, the CNBV may permit an 
offer for less than 100%). The tender offer must be made at the same price to all shareholders and classes of shares. 
The board of directors, with the advice of the audit and corporate governance committee, must issue its opinion in 
respect of the fairness of the price applicable to any mandatory tender offer, which may be accompanied by an 
independent fairness opinion. Directors and the chief executive officer of a public company, in respect of which a 
tender offer has been made, must disclose whether or not each of them will tender his respective shares in the tender 
offer.  

 
141 
 
Under the Mexican Securities Market Law, all tender offers must be open for at least 20 business days and 
purchases thereunder are required to be made pro rata to all tendering shareholders. The Mexican Securities Market 
Law also permits the payment of certain amounts to a controlling shareholder over and above the offering price if 
these amounts are fully disclosed, approved by the board of directors, and paid solely in connection with non-compete 
or similar obligations. The law also provides exceptions to the mandatory tender offer requirements and specifically 
sets forth remedies for non-compliance with these tender offer rules (e.g., suspension of voting rights, possible 
annulment of purchases, etc.) and other rights available to prior shareholders of the issuer.  
Anti-Takeover Protections  
The Mexican Securities Market Law provides that public companies may include anti-takeover provisions in 
their by-laws if such provisions (i) are approved by a majority of the shareholders, without shareholders representing 
20% or more of the capital stock present at the meeting voting against such provision, and (ii) do not contravene legal 
provisions related to tender offers or have the effect of disregarding the economic rights related to the shares held by 
the acquiring party.

Capital Stock 
Our capital stock is variable. The amount of the fixed portion of our capital stock that is not subject to rights 
of withdrawal is Ps.3,000, represented by two series C common, nominative shares no par value. As of December 31, 
2024, the two series C shares are held by the Company, and no economic or corporate rights might be exercised in 
connection therewith. The variable portion of our capital stock subject to rights of withdrawal is unlimited and 
represented by series A shares, which are ordinary, nominative, no par value and grant equal economic and corporate 
rights and obligations to their holders. As of December 31, 2024, the variable portion of our outstanding capital stock 
was comprised by 95,285,451 series A shares. Our series A shares may be subscribed to and paid for by Mexican or 
foreign individuals or corporations, as well as by any other foreign entities with or without legal entity. Our series B 
shares (which were ordinary, nominative, with no par value and grant the same economic and corporate rights and 
obligations to their holders) have been cancelled and at their time, were subscribed and paid by our Strategic Partners 
(otherwise referred to herein as the Sponsor) and the independent directors of the Company and were converted into 
series A shares as approved at an ordinary general shareholders’ meeting.  
On August 1, 2017, prior to the closing of our initial public offering in Mexico, Vista and its strategic 
partners, Vista Sponsor Holdings, L.P. (an entity controlled by senior personnel from Riverstone Investment Group 
LLC) together with Miguel Galuccio, Pablo Vera Pinto, Juan Garoby and Alejandro Cherñacov (collectively, the 
“Sponsor”), entered into a strategic partners agreement (“Strategic Partners Agreement”) in connection with the 
private placement of the Sponsor Warrants. Pursuant to the Strategic Partners Agreement, the parties agreed, among 
other things, (i) to purchase the Sponsor Warrants, (ii) that the Sponsor Warrants may be exercised without cash 
payment as described in “Item 10—Additional Information—Memorandum and Articles of Association—Warrants,” 
(iii) in the event that the warrants terminate early and the Sponsor Warrants expire without being exercised, the 
parties agreed to issue another security or instrument that permits them to purchase series A shares in the same 
manner as the expired Sponsor Warrants, and (iv) to certain lockup provisions, which have expired as of the date of 
this annual report. As of the date of this annual report, there are no outstanding warrants. As of the date of this annual 
report, and as a consequence of the exercise of all outstanding warrants on March 15, 2023, the Strategic Partners 
Agreement has come to an end as the terms thereof are no longer applicable.  
On March 22, 2018, a shareholders’ meeting authorized the Plan. That same shareholders’ meeting approved 
the reservation of 8,750,000 series A shares issued by the Company on December 18, 2017, for the implementation of 
the Plan. Additionally, the series A shares repurchased by the Company through our buy-back program may be 
allocated to the Plan. As of the date of this annual report, 11,284,006 series A shares have been vested and are 
outstanding in connection with the Plan. If all series A shares currently reserved for the Plan, in addition to all the 
shares repurchased through the ongoing buy-back program, became outstanding, our issued and outstanding share 
capital would increase 0.6% from 98,150,716 series A shares outstanding as of the date of this annual report to 
98,781,026 series A shares. See “Item 6—Directors, Senior Management and Employees—Long-Term Incentive 
Plan.”  
At an ordinary general shareholders’ meeting, our shareholders may approve the issuance of other types of 
shares including those who have special rights or limited rights to holders and/or securities with respect to such 
shares.  
Warrants 
On October 4, 2022, Vista held a warrant holders’ meeting during which the warrant holders approved the 
amendments to the warrant indenture and the global certificate that covers such Warrants proposed by the Company, 
by means of which a cashless exercise mechanism was implemented that entitled the warrant holders to, in their sole 
discretion or at Vista’s discretion (in the latter case, with respect to all outstanding warrants and without any further 

 
143 
 
request, notice or communication required to or from Holders or any other person), obtain one series A share for each 
31 Warrants owned.  
During the period between October 10, 2022 and March 7, 2023, the warrants holders exercised 75,144,465 
warrants, and as a result of such exercise, 2,424,015 additional series A shares became outstanding. 
On March 7, 2023, Vista concluded the process with the CNBV to update the registration of Vista’s warrants 
in the RNV enabling the Automatic Cashless Exercise. On March 15, 2023, by virtue of such Automatic Cashless 
Exercise, and after giving effect thereto, the 24,535,535 outstanding Warrants were exercised, equivalent to 791,439 
additional series A shares became outstanding. By virtue of the exercise of all warrants (i.e., those exercised by the 
Holders before the Automatic Cashless Exercise, plus those exercised pursuant to such Automatic Cashless Exercise), 
the total number of series A shares that became outstanding is 3,215,454. As of the date of this annual report, there 
are no outstanding warrants. 
Movements in Our Capital Stock  
Capital stock increases shall be made pursuant to resolutions adopted by our shareholders in general 
shareholders’ meetings.  
Increases of our capital stock in its fixed portion are approved by resolutions taken by our shareholders in 
extraordinary shareholders’ meetings, with a corresponding amendment to our bylaws, while the modification of our 
capital stock in its variable portion is approved in ordinary shareholders’ meetings, which shall be formalized before a 
notary public, without it being necessary that the relevant public deed is recorded before the public registry of 
commerce of our corporate domicile.  
Additionally, we may affect capital increases due to the capitalization of shareholders’ equity accounts, 
pursuant to Article 116 of Mexico’s General Law of Commercial Companies, or any other provision replacing it from 
time to time and other applicable law, through payment in cash or in kind, capitalization of liabilities or by any other 
means allowed by applicable law. Regarding the increases by means of capitalization of shareholders’ equity 
accounts, all shares shall have the right to the proportional part that correspond to them in the increase, without it 
being necessary to issue new shares representing the increase.  
Capital increases, except for those arising from our acquisition of our own securities, shall be recorded in a 
capital variation registry book, which we are required to maintain pursuant to Article 219 of Mexico’s General Law of 
Commercial Companies, or any other provision replacing it from time to time and other applicable law.  
We may keep unsubscribed shares resulting from capital increase in treasury, or otherwise cancel such 
shares, in both cases a prior capital decrease shall be resolved by a shareholders’ meeting to the extent necessary.  
Our capital stock may only be reduced upon approval of our shareholders through resolutions adopted by 
them in either ordinary or extraordinary shareholders’ meetings, in accordance with the provisions set forth in Article 
12 of our bylaws except for (i) the separation of shareholders as described in Article 206 of Mexico’s General Law of 
Commercial Companies or any other provision replacing it from time to time, and other applicable law; and (ii) the 
acquisition of our own shares in accordance with our bylaws, the Mexican Securities Market Law and other 
applicable law.  
We may only reduce the fixed portion of our capital stock upon approval of our shareholders through 
resolutions adopted by them at an extraordinary shareholders’ meeting, the amendment of our bylaws and the 
formalizing of the relevant meeting minutes before a notary public. We may also reduce the variable portion of our 
capital stock upon approval by our shareholders through resolutions adopted by them at an ordinary shareholders’ 
meeting, the minutes of which shall be formalized before a notary public; provided that when the shareholders 
exercise their separation right or when the decreases are a result of the reacquisition of our own shares, no resolution 
from the shareholders’ meeting will be needed.  
We may reduce our capital stock to absorb losses in the event that any shareholder exercises its right of 
separation pursuant to Article 206 of Mexico’s General Law of Commercial Companies, or any other provision 

 
144 
 
replacing it from time to time and other applicable law, as well as a result of the reacquisition by the Company of our 
own shares pursuant to our bylaws, or in any other case allowed under applicable law.  
Capital reductions to compensate losses will be carried out proportionally among all the shares representing 
our capital stock, without it being necessary to cancel shares since they do not have par value.  
Holders of securities that are part of the variable portion of our capital stock may not exercise their right of 
withdrawal described in Article 220 of Mexico’s General Law of Commercial Companies, or any other provision 
replacing it from time to time, pursuant to Article 50 of the Mexican Securities Market Law, any other provision 
replacing it from time to time and other applicable law.  
We shall register all capital reductions in our capital variations registry book, except for reductions resulting 
from repurchase of our own shares.  
Voting Rights 
Pursuant to our bylaws, each series of our shares grants the same rights and obligations to holders thereof, 
including economic rights, since all holders of the shares participate equally, without any distinction, in any dividend, 
repayment, amortization or distribution of any nature on the terms further described herein.  
Our bylaws provide that, we may issue shares of different series or classes, with no voting rights, with 
limited corporate rights or with limited voting rights. 
Non-voting shares shall not count for determining the necessary quorum to call to order a general 
shareholders’ meeting. Limited or restricted voting shares will count only in determining the necessary quorum to call 
to order shareholders’ meetings in which their vote is needed or special meetings.  
Resolutions adopted at any general shareholders’ meeting in which the issuance of shares with different 
series or classes is approved shall set forth the rights, limitations, restrictions and all other characteristics 
corresponding to such shares.  
Shareholders’ Meetings  
A general shareholders’ meeting acts as our supreme body and authority. General shareholders’ meetings 
may be ordinary or extraordinary, as well as special, and shall always be held in our corporate domicile, except for 
cases of force majeure or acts of God.  
Pursuant to Mexican law and our bylaws, general shareholders’ meetings require 15 calendar days’ advance 
notice to be legally convened upon first or subsequent calls. Extraordinary general shareholders’ meetings are 
convened to approve any of the matters referred to in Article 182 of Mexico’s General Law of Commercial 
Companies, Articles 48, 53 and 108 of the Mexican Securities Market Law, or any other provisions replacing them 
from time to time and other applicable law, as well as those provisions contained in Articles 9 and 19 of our bylaws. 
All other general shareholders’ meetings shall be ordinary meetings, including those meetings which address 
increases and reductions to the variable portion of our capital stock.  
Special shareholders’ meetings shall convene to handle any matter that may affect the rights granted to the 
holders of a series of our shares and shall be subject to the applicable provisions in our bylaws that were established 
for extraordinary general shareholders’ meetings, in respect to attendance and voting quorums, as well as 
formalization of minutes.  
An ordinary general shareholders’ meeting shall be held at least once each year within the first four months 
following the end of the previous fiscal year in order to approve the matters listed in the agenda for such meeting, the 
matters described in Article 181 of Mexico’s General Law of Commercial Companies, or any other provision 
replacing it from time to time, as well as to do any of the following:  
(i) 
discuss, approve or modify reports of the chairmen of both the audit committee and the corporate 
practices committee;  

 
145 
 
(ii)

IV, and Article 44, Section XI, of the Mexican Securities Market Law, or any other provision 
replacing them from time to time and other applicable law;  
(iii) 
discuss, approve or modify reports of the board of directors, pursuant to sub-paragraph (b) of 
Article 172 of Mexico’s General Law of Commercial Companies, or any other provision replacing

chairmen of both the audit committee and the corporate practices committee;  
(vii) 
determine the independence of directors;  
(viii) 
determine the maximum amount of corporate funds that may be used for the repurchase of our own 
securities;  
(ix) 
approve transactions that we intend to carry out in the course of the fiscal year, when such 
transactions, or a series of transactions considered together on an aggregate basis based on certain 
shared characteristics (as determined by the Mexican Securities Market Law), represent an amount 
that is 20% or more of our consolidated assets, determined on the basis of the value of our 
consolidated assets at the end of the immediately preceding quarter (in such meetings, the 
shareholders with limited or restricted voting rights may vote); and/or  
(x) 
handle any other matter in accordance with applicable law and that is not specifically reserved by 
law to be taken up at an extraordinary general shareholders’ meeting.  
An extraordinary general shareholders’ meeting shall handle any of the matters described in Article 182 of 
Mexico’s General Law of Commercial Companies or any other provision replacing it from time to time. In addition, 
shareholders at such an extraordinary meeting may do any of the following:  
(i) 
amend our bylaws to prevent an acquisition of our securities that would provide an acquirer or 
acquirers control of our Company;  
(ii) 
increase our capital stock pursuant to the terms of Article 53 of the Mexican Securities Market Law, 
or any other provision replacing it from time to time;  
(iii) 
cancel the registration any of our capital stock or the certificates representing such securities with 
the RNV;  
(iv) 
generally, amend our bylaws;  
(v)

(vi) 
handle any other matter in accordance with applicable law or our bylaws that expressly requires a 
special quorum or is specifically reserved by law to be taken up at an extraordinary general 
shareholders’ meeting.  
Any general shareholders’ meeting may be called by our board of directors, the Chairman of the Board of 
Directors, our Secretary or either the Audit Committee or Corporate Practices Committee. The holders of shares with 
voting rights representing 10% or more of our capital stock may also request a general shareholders’ meeting, 
individually or collectively, from the Chairman of the board of directors or to the relevant committee, notwithstanding 
the percentage set forth under Article 184 of Mexico’s General Law of Commercial Companies.  
A shareholder request for a general shareholders’ meeting may be granted so long as such request meets the 
requirements set forth in Article 185 of Mexico’s General Law of Commercial Companies, any other provision 
replacing it from time to time and other applicable law. If a call is not made within 15 calendar days following the 

 
146 
 
request date, a civil or district court judge of the Company’s domicile will make such a call at the request of any 
interested shareholder, who must prove the ownership of its shares for such purposes.  
Calls for general shareholders’ meetings shall be published in the electronic system established by the 
Mexican Ministry of Economy for such purposes and may be published in one of the newspapers of largest 
circulation in the corporate domicile of the Company within at least 15 calendar days prior to the date on which the 
relevant meeting is intended to take place, pursuant to applicable law.  
From the date of notice of a general shareholders’ meeting to the date on which the meeting is held, we will 
make available to the shareholders, in our offices, immediately and free of charge, all information that we may deem 
necessary to vote on matters at the meeting, including the forms described in Section III of Article 49 of the Mexican 
Securities Market Law, or any other provision replacing it from time to time and other applicable law.  
General shareholders’ meetings may be held without prior notice (as described above) in the event that all 
the shares representing the capital stock with voting rights, or the relevant series of shares (in the event of a special 
meeting) are present or represented at the time of the voting at a meeting.  
Notwithstanding the foregoing and in accordance with the second paragraph of Article 178 of Mexico’s 
General Law of Commercial Companies, or any other provision replacing it from time to time and other applicable 
law, shareholders may adopt resolutions by unanimous written consent without a meeting, which will have the same 
validity and effectiveness as if such resolutions had been approved in a general shareholders’ meeting.  
Shareholders may be represented at general shareholders’ meetings by an attorney-in-fact that has a power-
of-attorney granted pursuant to the forms described in Section III of Article 49 of the Mexican Securities Market Law, 
or any other provision replacing it from time to time and other applicable law or pursuant to a power of attorney 
granted pursuant to applicable law.  
To be admitted to a general shareholders’ meeting, shareholders shall be duly registered in our stock registry 
book managed in accordance with Article 128 of Mexico’s General Law of Commercial Companies, or any other 
provision replacing it from time to time and other applicable law, or they may present certificates issued by the 
Indeval or any other institution that acts as a depository of securities in accordance with the Mexican Securities 
Market Law.  
To attend a special or general shareholders’ meeting, the relevant shareholder must prove to the Secretary 
non-member of our board of directors that it does not require the prior approval by our board of directors pursuant to 
Article 9 of our bylaws.  
Ordinary and extraordinary general shareholders’ meetings shall be presided over by the Chairman of the 
board of directors or, in his or her absence, by such person as determined by the shareholders at the relevant meeting 
through a majority vote of shares present.  
The Secretary non-member of the board of directors or the Deputy Secretary shall act as secretary of the 
general shareholders’ meetings or, in his or her absence, by such person as determined by the shareholders at the 
relevant meeting through a majority vote of shares present.  
The chairman of the general shareholders’ meeting shall appoint one or more inspectors (escrutadores), from 
the shareholders, shareholders’ representatives or invitees attending the relevant meeting, who shall determine the 
existence or absence of a quorum, and who shall count the votes cast upon request by the chairman of the meeting.  
The secretary of the general shareholders’ meeting shall prepare the minutes of such meeting, such minutes 
to be transcribed into our general shareholders’ meetings’ minutes registry and signed by both the chairman and the 
secretary of the relevant meeting as well as by the individuals who acted as inspectors. Any records regarding such 
meetings that were not able to transact matters because of a lack of quorum shall also be signed by the chairman, the 
secretary and the inspectors of the relevant meeting.  
An ordinary general shareholders’ meeting shall be duly convened if, after first call of those present, at least 
50% of the outstanding shares representing our capital stock are represented at such meeting. Decisions of an ordinary 

 
147 
 
general shareholders’ meeting are approved by a simple majority of the shares with voting rights represented at such 
meeting. In the event of second or further calls, an ordinary general shareholders’ meeting shall be deemed duly 
convened, regardless of the number of present or represented shares, and decisions shall be approved by the simple 
majority of the shares present with voting rights.  
An extraordinary general shareholders’ meeting shall be duly convened if, after the first call, at least 75% of 
the outstanding shares representing our capital stock are represented at such meeting. In the event of second or further 
calls, an extraordinary general shareholders’ meeting shall be deemed duly convened if most of our common stock is 
represented.  
The resolutions adopted by an extraordinary shareholders’ meeting, irrespective of whether it was convened 
as the result of the first, second or subsequent call, will be valid if taken by a majority of the shares of our capital 
stock outstanding (and not held in treasury), except in the case of (i) cancellation of the registration with the RNV of 
the shares representing our capital stock or the warrants representing them, in which case the affirmative vote of 95% 
of the shares of our capital stock outstanding (and not held in treasury), will be required, and (ii) an amendment to our 
bylaws, in which case the affirmative vote of 65% of the shares of our capital stock outstanding (and not held in 
treasury), will be required.  
Unanimous written consents adopted outside general shareholders’ meeting shall be transcribed in our 
shareholders’ meetings minutes registry book. Files containing copies of the minutes from each general shareholders’ 
meeting and each unanimous written consent, along with attendance lists, proxies, call copies, if any, and documents 
submitted to discussion, such as board of directors’ reports, our financial statements and other relevant documents, 
shall be formed and kept by us.  
In the event that any minutes of a general shareholders’ meeting or any unanimous written consent cannot be 
registered in our shareholders’ meetings minutes registry book, we will formalize such minutes or unanimous written 
consent before a notary public in Mexico.  
The minutes of general shareholders’ meetings, as well as the records of such meetings that were not held 
due to lack of quorum, will be signed by Chairman and Secretary of such shareholders’ meetings.  
Profit distribution (dividends)  
Generally, at an annual ordinary general shareholders’ meeting, our Board of Directors presents the financial 
statements corresponding to the preceding fiscal year to the shareholders for their approval. Once the general 
shareholders’ meeting approves those financial statements, all of the shares outstanding at the time of the declaration 
of a dividend or other distribution have the right to participate in that dividend or distribution.  
Board of Directors  
Composition  
Our Board of Directors is responsible for the general oversight of our Company. The Board of Directors 
comprises a maximum of 21 directors, which number may be changed from time to time upon resolutions adopted at 
a general shareholders’ meeting, and of which at least 25% shall be independent pursuant to Articles 24 and 26 of the 
Mexican Securities Market Law, or any other provision replacing it from time to time and other applicable law.  
An alternate director may be appointed in place of each director; provided, however, that alternates for 
independent directors shall have the same independence qualifications of the independent director on whose behalf 
they are acting.  
Directors are considered independent when they meet the requirements for independence set forth in Article 
26 of the Mexican Securities Market Law, or any other provision replacing it from time to time and any other 
guidance or regulation issued by the CNBV.  

 
148 
 
Director independence is determined by resolution adopted at an ordinary general shareholders’ meeting. 
The CNBV prior right of hearing of the company and of the director, may reject the independence determination of 
any director within 30 Business Days’ notice of the initial determination of said director’s independence.  
Directors may or may not be shareholders and shall serve on the Board of Directors until removed and a 
successor is appointed, provided that at all times they shall have legal capacity to perform their duties and shall not be 
prevented from executing business. At all times the provisions contained in the second paragraph of Article 24 of the 
Mexican Securities Market Law shall be complied with.  
The Board of Directors may appoint provisional directors, without input from a shareholders’ meeting, in the 
case of the death or disability of a director or expiration of his or her term. A general shareholders’ meeting shall 
ratify such appointments or appoint the new directors in the meeting following such event.  
Directors may only be removed by resolution adopted at an ordinary general shareholders’ meeting.  
Directors shall be appointed by a majority vote of shareholders at an ordinary general shareholders’ meeting; 
provided that for each 10% of outstanding capital stock held, a minority holder has the right to appoint one director.  
Each year, the Chairman of the Board of Directors shall be appointed either at a general shareholders’ 
meeting or at a meeting of the Board of Directors. The chairman of the Board of Directors shall execute and carry out 
resolutions adopted at general shareholders’ meetings and meetings of the Board of Directors without the need for a 
special resolution.  
The Secretary non-member of the Board of Directors and the Deputy Secretary shall be appointed at either 
an ordinary general shareholders’ meeting or at a meeting of the Board of Directors, as applicable. The Secretary shall 
not be a director but must carry out the obligations and duties prescribed by applicable law.  
Temporary or permanent absences in the board of directors shall be covered by such directors’ appointed 
alternates. The Chairman of the board of directors shall have a tie-breaking vote in all matters.  
The Chairman of the board of directors may be of any nationality, will chair the meetings of the Board of 
Directors and, in his or her absence, such meetings will be chaired by one of the directors appointed by a majority 
vote of the other attending directors.  
Meetings of the Board of Directors  
A meeting of the Board of Directors may be called either by the chairman of the Board of Directors, the 
chairman of the audit committee, the chairman of the corporate practices committee, the Secretary non-member of the 
Board of Directors or 25% of the directors by means of written notice, including, but not limited to, fax or email, to 
all directors at least ten calendar days prior to the date set for such meeting. In the event that all directors are present, 
a meeting may be called to order without advance notice.  
Our independent auditor may be called to attend any meeting of the Board of Directors with the right to 
speak but without voting rights; provided, however, that such auditor will never be present when matters which may 
raise a conflict of interest are discussed or that may compromise their independence.  
Meetings of the Board of Directors shall be held at least four times during each fiscal year, in the corporate 
domicile of our Company, however, a meeting may be held outside of our corporate domicile or abroad if a majority 
of the directors approves it, and to allow meetings of the Board of Directors to be held by telephone or by video 
conference or by any other means that enables the effective and simultaneous participation of its members.  
The minutes of meetings of the Board of Directors shall be transcribed into the Board of Directors’ meetings 
minutes book and shall be signed by all persons in attendance or, if expressly authorized by agreement at the meeting, 
solely by the Chairman of the Board of Directors and the Secretary non-member of the Board of Directors. A record 
and copies of the minutes and/or unanimous written consents of each meeting of the Board of Directors, as well as 
transcripts of any calls and any relevant documents regarding meetings, shall be kept by us.  

 
149 
 
A meeting of the Board of Directors may be duly convened when a majority of directors are present. The 
Board of Directors shall make decisions through resolutions adopted by a majority vote of directors; in the event of a 
tie, the chairman of the Board of Directors shall cast the deciding vote.  
Will be valid and legal all decisions made outside of meetings of the Board of Directors as long as taken by 
unanimous written consent of all directors and signed by all of the directors. The document in which the written 
confirmation is evidenced shall be sent to the Secretary of the Company, who will transcribe the relevant resolutions 
in the corresponding minutes book and shall indicate that such resolutions were adopted pursuant to our bylaws.

of a minimum of three independent directors appointed by the Board of Directors, pursuant to the terms set forth in

bylaws, shall meet in the form and frequency established by each such committee in the first or last board meeting 
held during each year (in the latter case regarding the calendar of meetings to be held during the following fiscal

in accordance with the meeting calendar approved by the relevant committee for such purposes; provided, however,

been approved in the session as long as they are approved by unanimous written consent of all committee members 
and signed by all of the members thereof. Likewise, the committees may meet at any moment, without prior notice, if 
all members are present.  
Committees may not delegate their authorities as a whole to any person, but they may appoint deputies to 
implement their resolutions. The chairman of each committee will be entitled to individually implement such 
resolutions without needing express authorization. Each committee created pursuant to our bylaws shall inform the 
Board of Directors on an annual basis about the activities it performs or when it considers that facts or actions 
material for the Company have occurred. Minutes shall be prepared for each meeting of a committee, which shall be 
transcribed in a special minutes book. The minutes shall evidence the attendance of the members of the committee 
and the resolutions adopted, and they shall be signed by the individuals present and the Chairman and Secretary.  
Meetings of the Committees may be held by telephone or by video conference or by any other means that 
enables the effective and simultaneous participation of its members. 
For all that is not provided herein or in the Mexican Securities Market Law, committees shall operate 
pursuant to rules set by our Board of Directors, unless otherwise prescribed in our bylaws or in the Mexican 
Securities Market Law.  
Committees shall keep the Board of Directors appraised of their activities at least once a year.  
Duties of Directors  
The Mexican Securities Market Law imposes a duty of diligence and loyalty on the members of the board of 
directors, the members of the board’s committees, the chief executive officer and on the relevant officers from which 
the chief executive officer seeks assistance. Such duty of diligence requires them to obtain sufficient information and 
to be sufficiently prepared in order to act in the best interest of the Company. The duty of diligence is complied with, 
mainly, by searching for and obtaining all the information that may be necessary in order to make decisions 
(including by means of hiring independent experts), attending sessions of the board of directors, of the committee in 
which they participate and disclosing to the board of directors relevant information in the possession of the relevant 
director or officer. Default of such duty of diligence by a board member subjects him or her to joint liability along 
with other board members that are liable in connection with the damages and lost profits caused to the Company or its 
subsidiaries.  
The duty of loyalty mainly consists of a duty to act in the best interest of the Company and includes, 
primarily, the duty to maintain confidentiality of the information that the board members receive in connection with 
the performance of their duties, abstaining from voting in matters in respect to which they have a conflict of interest 
and abstaining from taking advantage of business opportunities of the Company. It is a violation of the duty of loyalty 
for a director to take actions that wrongfully benefit one or more shareholders, or for a director, without prior express 
consent of the disinterested members of the board of directors, to take a corporate opportunity that belongs to the 
Company or its subsidiaries.  
It is also a violation of the duty of loyalty for a director to (i) use our assets, or consents to the use of our 
assets, in violation of any of our policies or (ii) disclose false or misleading information, order not to record, or 
prevent the recording of any transaction in our registries, which could affect our financial statements or cause 
important information to be improperly modified or not disclosed.  
A director’s failure to comply with the duty of diligence or the duty of loyalty shall make him or her jointly 
liable with other directors or officers who have also failed to comply therewith for any damages caused to our 
Company resulting therefrom in the cases in which they have acted in bad faith, willfully or illegally.  
 

 
152 
 
As a means of protection for our board members regarding breaches of the duty of diligence or the duty of 
loyalty, the Mexican Securities Market Law provides that directors will not be liable for the breach of such duties in 
the event that the board member acted in good faith and (a) in compliance with applicable law and our bylaws, 
(b) based on facts and information provided by our officers, independent auditors or experts whose credibility and 
reliability may not be reasonably questioned, and (c) elects the most suitable alternative in good faith or when the 
negative effects of such decision may not be reasonably foreseen based on the information available. Mexican courts 
have not interpreted the meaning of such provision and, therefore, its scope and meaning are uncertain.  
Board members will be jointly liable with previous board members regarding irregularities caused by any 
prior board member if such irregularities are not reported to the audit committee and the corporate practices 
committee.  
The members of the board of directors and the committees have no obligation to guarantee the performance 
of their positions.  
The provisions regarding the duty of loyalty of the second and third paragraphs of Article 34 of the 
Securities Market Law must be observed.  
The liability resulting from the breach of the duty of diligence or the duty of loyalty should be exclusive in 
favor of the Company, as the case may be, and may be exercised by the Company or by the shareholders who, 
individually or jointly, represent ownership of shares (including limited, restricted or non-voting shares) representing 
5% or more of the share capital.  
The members of the Board of Directors or the members of the committees should not be in default when they 
act in good faith or when any liability exclusion mentioned in Article 40 of the Mexican Securities Market Law, any 
other provision replacing it from time to time and other applicable law.  
Audit and Corporate Practices Committees  
The oversight of our management and conduct and execution of our business shall be vested in the board of 
directors through the Audit Committee and the Corporate Practices Committee, as well as our independent auditor.  
The chairman of the audit committee and the chairman of the corporate practices committee shall be bound 
to provide an annual report pursuant to Article 43 of the Mexican Securities Market Law or any other provision 
replacing it from time to time.  
Audit Committee  
The audit committee shall be comprised of a minimum of three members, who shall be independent and shall 
be appointed at a general shareholders’ meeting or a meeting of the board of directors upon a proposal by the 
Chairman of the board of directors, except for the chairman of the Audit Committee, who shall be appointed and/or 
removed from office exclusively by resolution adopted at a general shareholders’ meeting. The chairman of the Audit 
Committee must also satisfy the requirements described in Article 43, Section II of the Mexican Securities Market 
Law to serve.  
The audit committee shall perform the functions described in Article 42, Section II of the Mexican Securities 
Market Law, any other provision replacing it from time to time, guidance and/or regulation handed down by the 
CNBV and other applicable law. These functions include, but are not limited to giving an opinion to the board of 
directors about matters entrusted to the Audit Committee, discussing the financial statements of our Company with 
the persons responsible for preparing them, informing the board of directors about the state of affairs concerning the 
internal control and audit systems of our Company, preparing an opinion about accounting policies and criteria and, in 
general, overseeing the corporate conduct of our Company.  
We shall have an independent auditor to perform audits in compliance with the Mexican Securities Market 
Law.  

 
153 
 
Corporate Practices Committee  
The corporate practices shall be comprised of a minimum of three members, who shall be independent and 
shall be appointed at a general shareholders’ meeting or a meeting of the Board of Directors upon a proposal by the 
Chairman of the board of directors, except for the chairman of the Corporate Practices Committee, who shall be 
appointed and/or removed from office exclusively by resolution adopted at a general shareholders’ meeting. The 
chairman of the Corporate Practices Committee must also satisfy the requirements described in Article 43, Section I 
of the Mexican Securities Market Law to serve.  
The corporate practices committee shall have the functions described in Article 42, Section I of the Mexican 
Securities Market Law, any other provision replacing it from time to time, guidance and/or regulation handed down 
by the CNBV and other applicable law. These functions include, among others derived from the Mexican Securities 
Market Law, issuing an opinion to the board of directors as requested about matters related to compliance with the 
Mexican Securities Market Law and our bylaws, requesting opinions from independent experts in connection with 
matters to be submitted for approval to the board of directors or in respect to which there is a conflict of interest, 
calling shareholders’ meetings and supporting the board of directors in the preparation of reports.  
Indemnification 
Pursuant to our bylaws, we shall indemnify and hold harmless the members, alternates and officers of the 
Board of Directors, the Audit Committee, the Corporate Practices Committee, any other Committees created by us, 
the Secretary and the Deputy Secretary non-members of the Board of Directors, and the Chief Executive Officer and 
other relevant officers, in relation to the performance of their duties, such as any claim, demand, proceeding or 
investigation initiated in Mexico or in any of the countries in which our shares are registered or listed, other securities 
issued on the basis of such shares or other fixed or variable income securities issued by us, or in any jurisdiction 
where we, or the companies we control, operate, in which such persons may be parties as members of such bodies, 
owners or alternates, and officials, including the payment of any damages or losses that have been caused and the 
amounts necessary to arrive, if deemed appropriate, to a transaction, as well as the total fees and expenses of lawyers 
(reasonably and documented) and other advisors to be retained to ensure the interests of such persons in the 
aforementioned cases, on the understanding that the Board of Directors shall be the body empowered to resolve, in the 
aforementioned cases, whether it considers convenient to retain the services of lawyers and other different advisors to 
those who are advising us in the relevant case. This indemnity shall not apply if such claims, demands, proceedings or 
investigations result from gross negligence, willful misconduct, bad faith or illegally pursuant to the applicable law of 
the indemnified party concerned. Furthermore, we may purchase, in favor of the members of the Board of Directors, 
the Audit Committee, the Corporate Practices Committee and any other committees formed by us, of the Chief 
Executive Officer or any other relevant officer, the insurance, bond or guarantee which covers the amount of the 
indemnity for the damages caused by his/her performance within our organization or entities controlled by us or in 
which we have significant influence, except in the event of acts of malice or bad faith, or illicit acts in accordance 
with the Mexican Securities Market Law or other applicable law. 
Dissolution and Liquidation  
The Company shall be dissolved upon occurrence of any of the events described in Article 229 of Mexico’s 
General Law of Commercial Companies, any other provision replacing it from time to time and other applicable law. 
In each case, the registration with the RNV of the shares representing the capital stock of the Company and the 
warrants representing such shares shall be canceled.  
Once the Company has been dissolved, it shall be placed in liquidation, which would be administered by one 
or more liquidators, who in such case shall act together as determined by resolution at a general shareholders’ 
meeting. Such general shareholders’ meeting will also set the termination date of the liquidator’s employment with 
the Company and their compensation.  
The liquidator or liquidators will proceed with the liquidation and the pro rata distribution of the value of the 
remaining assets of the Company, if any, to shareholders, in accordance with Mexico’s General Law of Commercial 
Companies.  

 
154 
 
Preferred Subscription Rights  
Except for the capital increases approved by the shareholders’ meetings, shareholders shall have, in 
proportion to the number of shares they hold when the relevant increase is resolved, preemptive rights to subscribe for 
new stock issuances to maintain their current percentage of ownership. The foregoing preemptive right must be 
exercised within 15 calendar days following our approval of such new stock issuance, as published in the electronic

We may redeem shares with distributable profits without need to reduce our capital stock; provided that, in 
addition to complying with Article 136 of Mexico’s General Law of Commercial Companies, or any other provision 
replacing them from time to time and other applicable law, we comply with the following:  
• 
if the redemption is intended to redeem all shares held by our shareholders, such redemption shall 
be made so that the shareholders shall continue to have the same proportion of shares they had 
before such redemption took place;  
• 
if the redemption is intended to redeem shares that are listed on a stock exchange, such redemption 
will be made through the acquisition of our own shares on such said stock exchange in accordance 
with the terms and conditions approved by resolution at a general shareholders’ meeting, which 
may delegate to the board of directors or special deputies the authority to determine the system, 
prices, terms and other conditions for that end and the relevant shareholders’ resolutions shall be

any other provision replacing it from time to time provided that certain requirements are fulfilled;  

 
155

Restrictions on the Transfer of Shares  
Every direct or indirect acquisition or attempted acquisition of our capital stock of any nature and regardless 
of the name it is given, under any title or legal structure, with the intention of carrying-out, be it in one or several 
simultaneous or successive transactions or acts of any legal capacity, with no time limitation between them, in a 
private transaction or through a stock exchange, whether in Mexico or abroad, including structured transactions such 
as mergers, corporate restructures, spin-offs, consolidations, allocations or guaranties executions or other similar 
transactions or legal acts (any such operation, an “Acquisition”), by one or more persons, related persons (grupo de 
personas or “group”) under the Mexican Securities Market Law, business group or consortium, will require approval 
through a written resolution adopted by our board of directors, each time that the number of shares to be acquired, 
when added to any shares already owned, results in the acquiring party 10% or more of our capital stock. Once a 
holder holds such percentage of our capital stock, the holder must notify the board of directors through notice 
provided to the Chairman or Secretary, in our corporate domicile, of any subsequent acquisition of 2% or more of our 
outstanding capital stock. For the avoidance of doubt, no additional authorization is required to carry-out such 
acquisitions or to execute a voting agreement until the ownership percentage in our outstanding capital stock is equal 
to or greater than 20%.  
Shareholders must request a favorable opinion from the board of directors, in writing, for the execution of 
written or oral agreements, regardless of their name or title or classification, as a consequence of which voting 
associations, block voting or binding or joint voting mechanisms or covenants are formed or adopted or certain shares 
are combined or shared in any other manner, such agreement resulting in a change of control of our Company or an 
effective 20% ownership of our outstanding capital stock (each, a Voting Agreement and jointly, the Voting 
Agreements), except for temporary Voting Agreements that are executed in connection with a general shareholders’ 
meeting, with the purpose of appointing minority members of the board of directors.  
For such purposes, the person who individually, or jointly with related persons, group, business group or 
consortium that intends to carry out any Acquisition or execute any Voting Agreement, shall make a written 
authorization request to the board of directors and shall contain the following information:  
•

persons thereof, the group, business group or consortium (a) be it as an owner or co-owner, directly or 
through any person or related person, and/or (b) regarding shares subject to an executed Voting 
Agreement;  
•

subsections (i) and (ii) above represent of our issued and outstanding shares; provided that for (a) and 
(b) the total of our issued and outstanding shares may be determined by the total number of shares that 
we report as outstanding to the stock exchange on which they are listed;  

 
156 
 
•

the reasons and objectives pursuant to which the person or persons, group of persons, business group or 
consortium that intends to carry-out an Acquisition or execute a Voting Agreement, in particular if they 
intend to acquire, directly or indirectly, (a) shares in addition to those referred in the authorization 
request, (b) 20% ownership of our capital stock, (c) control of our Company, or (d) significant influence 
in our Company, as well as the intended role with respect to the policies and management of our 
Company and any amendment they would like to propose with respect to the policies and management 
of our Company;  
• 
if the person or persons, group, business group or consortium have direct or indirect ownership in the 
capital stock or in the management and operation of a competitor or any related person to a competitor, 
if they have any economic or business relationship with a competitor or with any related person to a 
competitor or if any related person of theirs is a competitor;  
• 
if they have the authority to acquire shares or execute a Voting Agreement, in accordance with our 
bylaws and applicable law, or if they are in the process of obtaining any such authorization or consent 
from any person, and the terms and timing on which they expect to obtain it;  
• 
the origin of the funds they intend to use to pay the price of the shares requested; provided that with 
respect to funds obtained from financing, the requesting party shall specify the identity and nationality 
of the person providing such funding and if such person is a competitor or a related person to a 
competitor, and any documentation evidencing the financing and the terms and conditions thereof. The 
board of directors may request from the person that sends such a request, if considered necessary to 
guarantee the payment of the corresponding Acquisition price and before granting authorization in 
accordance with the above, additional evidence regarding the financing (including evidence that there 
are no prohibitive covenants pursuant to such financing) or, the formation or granting of a (a) bailment, 
(b) guarantee trust, (c) irrevocable letter of credit, (d) deposit or (e) any other type of guarantee, up to 
the equivalent amount of 100% of the price of the shares that are to be acquired or that are the subject 
matter of the corresponding transaction or agreement, naming the shareholders, directly or through our 
Company, as beneficiaries, with the purposes of securing the compensation of the losses and lost profits 
that our Company or its shareholders may suffer as a consequence of the incorrect information presented 
or of the request, or for any action or omission of the petitioner, directly or indirectly, or as a 
consequence of the impossibility to complete the relevant transaction, for any cause, related or not to the 
financing;  
• 
the identity and nationality of the financial institution that would act as broker, in the event that the 
Acquisition in question is through a public offering;  
• 
if, there is to be a public offering, a copy of the offering circular or similar document, to be used for the 
acquisition of the shares or regarding the corresponding transaction or agreement, and a representation 
stating if such document has been authorized by the competent regulatory authorities (including the 
CNBV); and  
• 
a domicile in Mexico City, Mexico, to receive notices regarding the filed request.  
In the event that the board of directors resolves, due to the impossibility of knowing certain information upon 
receiving the request, that such information may not yet be disclosed, the board of directors may, at its sole discretion, 
waive the compliance of one or more of the aforementioned requirements:  
• 
within 15 business days following the date upon which the request referred to above has been received, 
the Chairman or Secretary shall call a meeting of the board of directors to discuss and resolve the matter 

 
157 
 
of the requested authorization (notice for such meetings shall be made in writing and sent in accordance 
with our bylaws); and  
• 
the board of directors may request from the person intending to carry-out the Acquisition or execute the 
corresponding Voting Agreement, additional documentation and clarifications as it sees fit to adequately 
analyze the request, to agree upon the authorization request as filed; provided that any request of such 
nature on behalf of the board of directors shall be made during the subsequent 20 calendar days 
following the receipt of the request, and provided that such request will not be considered as final and 
complete until the person who intends to carry-out the Acquisition or execute the Voting Agreement, 
files all the additional information and makes all the clarifications requested by the Board of Directors.  
The board of directors shall resolve any authorization request it receives pursuant to the terms of our bylaws 
within 90 calendar days following the delivery of the request or on the date in which such request is finalized as 
discussed above.  
The board of directors shall adopt a resolution approving or rejecting the request; provided that if the board 
of directors does not issue such resolution within the aforementioned 90-calendar days, the request shall be deemed as 
rejected. In all cases, the board of directors will act in accordance with the guidelines set forth in “Item 10—
Additional Information—Memorandum and Articles of Association” and shall justify their decision in writing.  
• 
To consider a meeting of the board of directors duly convened, by first or subsequent call, to deal with any 
matter regarding an authorization request or agreement referred herein, the attendance of at least 66% of 
incumbent directors or their alternates is required. Such resolutions will be valid and adopted when approved 
by 66% of the members of the Board of Directors.  
• 
In the event that the board of directors authorizes the requested Acquisition or the execution of a proposed 
Voting Agreement, and such Acquisition or agreement results or would be likely to result in (a) the 
acquisition of 30% or more of our capital stock or, but without involving a change of control, in addition to 
any authorization requirement established in our bylaws, the person or group intending to carry out the 
Acquisition or enter into the Voting Agreement the acquisitions of shares or the conclusion of the respective 
Voting Agreement which is the object of the authorization, shall first execute a tender offer for the greater of 
(i) the percentage of the Company’s capital stock equivalent to the proportion of shares in circulation that is 
intended to be acquired or (ii) 10% of the Company’s capital stock, under the authorized conditions resolved 
by the board of directors, or (b) a change of control, in addition to any authorization requirement established 
in our bylaws, the person or group, intending to carry out the Acquisition or execute the Voting Agreement, 
shall first execute a tender offer for 100% of our outstanding shares, under the authorized conditions 
resolved by the board of directors. The tender offer referred to in the paragraph above shall be completed 
within 90 calendar days following the date on which the authorization was granted by the Board of 
Directors; provided that such term may be extended by an additional 60 calendar days in the event that any 
relevant governmental authorizations required for such purposes are pending.  
The price to be paid for each of the shares will be the same, regardless of their class or series.  
In the event that the board of directors receives, prior to or at the completion of the Acquisition or the 
execution of a Voting Agreement, an offer from a third-party, stated in a request to carry out an acquisition of at least 
the same amount of shares, on better terms for the owners and shareholders of the Company (including type of 
compensation and price), the board of directors will have the authority to consider, after the submission of both 
requests, and to authorize such a second request, suspending the authorization previously granted; provided that any 
approval shall have no effects on the obligation of carrying out a tender offer in accordance with our bylaws and 
applicable law.  
• 
Acquisitions that do not result in (i) the acquisition of 20% of our capital stock or (ii) a change of control or 
(iii) the acquisition of significant influence regarding the Company may be registered in our stock registry 
book after authorization by the board of directors and the completion of such transactions. Acquisitions or 
Voting Agreements that result in (i) or (ii) above, may be registered in our stock registry book upon the 
completion of a tender offer pursuant to the terms discussed above. Consequently, in such case it will not be 
possible to exercise the rights arising from the shares until such tender offer is concluded.  

 
158 
 
• 
The board of directors may deny authorization for a requested Acquisition or for the execution of a proposed 
Voting Agreement, in which case it will inform, in writing, the basis and reasons for such denial. The 
requesting party will have the right to request and hold a meeting with the board of directors, or with an ad-
hoc committee appointed thereby, to explain, extend or clarify the terms of its request, as well as 
communicate its position in writing to the board of directors.  
General Provisions  
For the purposes herein, it is to be understood that shares belong to the same person, when such shares are 
(i) owned by any related person or (ii) owned by any entity, provided that such entity is owned by the aforementioned 
person. Likewise, a person or group that acted jointly or coordinated with others to acquire shares, regardless of the 
legality of such transaction, whether through simultaneous or successive transactions will be deemed as the same 
person for the purposes herein. The board of directors will determine if one or more persons that intend to acquire 
shares or execute Voting Agreements shall be considered as the same person for the purposes set forth herein.  
In its assessments of authorization requests, the board of directors shall take into consideration the following 
factors and any other as deemed pertinent, acting in good faith and in the best interests of our Company and 
shareholders and in compliance with their duties of loyalty and diligence pursuant to the terms of the Mexican 
Securities Market Law and our bylaws: (i) the price offered by the potential buyer and the type of compensation 
planned as part of such offer; (ii) any other relevant terms or conditions included in such offer such as to the viability 
of the offer and the origin of the funds to be used for the acquisition; (iii) the credibility, solvency and reputation of 
the potential buyer; (iv) the effect of the proposed Acquisition or the proposed Voting Agreement on our business, 
including our financial and operational position as well as our business prospects; (v) potential conflicts of interest 
(including those where the person making the request is a competitor, or an affiliate of a competitor, as described in 
the paragraphs above) in the event that the Acquisition or Voting Agreement is not with regard to 100% of the shares; 
(vi) the reasons stated by the requestor to carry out the Acquisition or execute the Voting Agreement; and (vii) the 
quality, precision and truthfulness of the information provided in the request.  
If the Acquisition or the execution of a Voting Agreement is to occur, without first receiving authorization in 
advance and in writing from the board of directors, the shares part of such Acquisition or in connection with such 
Voting Agreement will not be granted any rights to vote in any general shareholders’ meeting and will be made at the 
buyer’s, group of buyers’ or parties’ to the relevant contract, agreement or covenant own liability. The shares part of 
such Acquisition or Voting Agreement that has not been approved by the board of directors shall not be registered in 
our stock registry book, the entries made beforehand shall be canceled and we shall not acknowledge or give any 
value to the records or listings as described in Article 290 of the Mexican Securities Market Law, or any other 
provision which might replace it from time to time and other applicable law, and they shall not be considered as proof 
of ownership of shares or grant attendance rights for general shareholders’ meetings and shall give no legitimacy for 
the exercise of any legal action, including those of a procedural nature.  
The authorizations granted by the board of directors described above will have no effect if the information 
and documentation on which the authorization was based and granted is not true, complete and/or legal.  
In the event of any failure to comply with what is set forth above, the board of directors may adopt, among 
others, the following measures: (i) the rescission of the transactions, with mutual restitution to the parties thereto, or 
(ii) the sale of the shares part of such Acquisition, to a third-party approved by the board of directors at the minimum 
reference price as determined by the Board of Directors.  
The above shall not be applicable to (i) share acquisitions through inheritance or legacy or to affiliates or 
vehicles wholly controlled by the person or entity carrying out the transfer, (ii) share acquisition or the execution of a 
Voting Agreement by us, or by a trust formed by us, (iii) share acquisition made by Strategic Partner or (iv) the 
transfer into a control trust or similar entity which the shareholders may form at the time of an initial public offering 
of our shares in Mexico.  
The above applies in addition to the statutes and general rules regarding the acquisition of securities in the 
markets in which the shares, other securities related thereto or rights derived therefrom are listed. In the event that our 
bylaws run counter, in part or in whole, to any laws or general provisions thereof, then such laws shall prevail.  

 
159 
 
These provisions of our bylaws will be registered with the public registry of commerce of our domicile and 
shall be transcribed in the share certificates representing our capital stock in order to be opposable vis-à-vis third 
parties. The provisions included of our bylaws described above with respect to restrictions on transfers of shares may 
only be amended or removed from the bylaws by resolution upon approval of at least 95% of the Company’s shares at 
the time of such resolution.  
Delisting or Cancellation of the Registration of the Shares with the RNV  
In the event that we decide to cancel the registration of our series A shares before Mexico’s National 
Securities Registry by resolution adopted at an extraordinary general shareholders’ meeting, upon approval of at least 
95% of our capital stock or if our registration is canceled by resolution of the CNBV after this offering is completed, 
prior to such cancellation, we shall make a tender offer within a maximum period of 180 calendar days beginning at 
the time in which the demand or authorization from the CNBV, as the case may be, becomes effective, in accordance 
with Article 108 of the Mexican Securities Market Law, or any other provision replacing it from time to time and 
other applicable law. That offer shall be extended solely to those persons who do not belong to the group of 
shareholders that exercises control over us. Shareholders exercising control (as defined in the Mexican Securities 
Market Law) will be collaterally liable to the Company for carrying out a tender offer of the outstanding shares in the 
event of our liquidation or a cancellation request from the CNBV.  
In accordance with Article 108 of the Mexican Securities Market Law and Article 101 of the Mexican 
Securities Market Law, our board of directors shall prepare, no later than the tenth Business Day after the beginning 
of the public tender offer, a hearing of the Audit and Corporate Practices Committee, and shall disclose to the 
investing public, its opinion with respect to the price of the public tender offer and the conflict of interests that, as the 
case may be, each of the members of the board of directors has in connection with the offering. Such opinion may be 
accompanied with another one issued by an independent expert. Likewise, the members of the board of directors and 
the Chief Executive Officer of the Company shall disclose to the public, along with the opinion, the decision they will 
take with respect to the shares of the Company they own and the derivative securities of the Company they own.  
Loss of Rights over the Shares  
We are incorporated under the laws of Mexico. As required by Mexican law, any non-Mexican who, either at 
the time of our incorporation or at any time thereafter, acquires shares or any interest, formally undertakes, before the 
Mexican Ministry of Foreign Affairs, to be considered as a Mexican national with respect to its interests in the 
Company, as well as the property, rights, concessions, participation or interests held by the Company, and the rights 
and obligations deriving from the agreements to which the Company is a party, and further undertakes not to invoke 
the protection of its home government with respect to such interest. Upon the breach of such undertaking, such person 
is under penalty of forfeiting such shares or interests in favor of the Mexican government. Mexican law requires that 
such a provision be included in the bylaws of all Mexican corporations unless such bylaws or applicable law prohibit 
ownership of shares by non-Mexican persons.  
Reductions of our capital stock may be resolved to absorb losses in the event that any shareholder exercises 
its right of separation in terms of Article 206 of Mexico’s General Law of Commercial Companies, or any other 
provision replacing it from time to time and other applicable law.  
MATERIAL CONTRACTS 
For information regarding our material contracts, see “Item 4—Information on the Company—Business 
Overview—Our Operations—Argentina—Concessions” and “Item 5.B Liquidity and Capital Resources—
Indebtedness.” 
EXCHANGE CONTROLS 
From 1991 until the end of 2001, Law No. 23,928 (Convertibility Law) established a fixed exchange rate of 
AR$ 1/US$. On January 6, 2002, Law No. 25,561 formally put an end to that U.S. Dollar-Argentine Peso parity. 
Following a brief period during which the Argentine government established a temporary dual exchange rate system 
pursuant to the Law No. 25,561, the Argentine Peso has been allowed to float freely against other currencies since 
February 2002, although the Argentine government has the power to intervene by buying and selling foreign currency 

 
160 
 
on its own account, a practice in which it engages on a regular basis. On December 23, 2019, Law No. 27,541 
(“Solidarity Law”) was published, which again declared the public emergency until December 31, 2020. See “Item 
3—Key Information—Risk Factors—Detailed Risk Factors—Risks Related to the Argentine and Mexican Economic 
and Regulatory Environments—Significant fluctuations in the value of the Argentine Peso could adversely affect the 
Argentine economy and our business and results of operations in Argentina.” 
Currency controls that tightened restrictions on capital flows, and the official exchange rate between the 
Argentine Peso and the U.S. Dollar and transfer restrictions that substantially limit the ability of companies to retain 
foreign currency or make payments abroad are currently in place in Argentina and have been for alternating periods 
during the past years. By means of Decree No. 609/2019 dated September 1, 2019, as amended, the Argentine 
Executive Branch reinstated foreign exchange controls and authorized the BCRA to (a) regulate access to the foreign 
exchange market for the purchase of foreign currency and outward remittances; and (b) set forth regulations to avoid 
practices and transactions aimed at eluding, through the use of securities and other instruments, the measures adopted 
through the Decree No. 609/2019. At present, foreign exchange regulations have been (i) extended indefinitely, and 
(ii) consolidated in a single set of regulations, Communication “A” 7,914, as subsequently amended and 
supplemented from time to time by BCRA’s communications (“Argentine Foreign Exchange Regulations”).  
The BCRA requested the Argentine Securities Commission (Comisión Nacional de Valores) (“CNV”) to 
implement aligned measures to avoid elusive practices and operations. In this sense, the CNV, in line with the 
provisions of Section 3 of the Decree, established various measures to avoid such elusive practices and operations. 
The following table sets forth the annual low, high, average and period-end exchange rates for the periods 
indicated, expressed in nominal Argentine Peso per U.S. Dollar, based on rates quoted by the BCRA (Communication 
“A” 3,500). The Federal Reserve Bank of New York does not report a noon buying rate for the Argentine Peso.

Specific Provisions For Income From The Foreign Exchange Market 
Entry and Settlement of the Proceeds from the Export of Goods Through the Foreign Exchange Market 
The Argentine Foreign Exchange Regulations established that revenues from exports of goods must be 
entered and settled in Argentine Pesos through the foreign exchange market and proceeds from exports of goods must 
be entered and settled through the foreign exchange market within 20 business days following their collection. 
Decree No. 28/2023 published on December 13, 2023, established: (i) the export countervalue of the services 
included in Subsection c) of paragraph 2 of Section 10 of Law No. 22,415 (Código Aduanero) and its amendments 
(which refers to services rendered in Argentina, with effective use or exploitation carried out abroad); and (ii) the 
countervalue of the export of goods included in the Common Nomenclature of MERCOSUR (“NCM”), including pre-
financing and/or post-financing of exports from abroad or a liquidation advance; 80% of such countervalue must be 
brought into the country in foreign currency and/or negotiated through the foreign exchange market, and for the 
remaining 20% must be carried out through purchase and sale transactions with negotiable securities acquired with 
liquidation in foreign currency and sold with liquidation in local currency. 

 
161 
 
In the case of funds received or credited abroad, the deposit and liquidation for the amount equivalent to the 
usual expenses debited by the financial entities abroad for the transfer of funds to the country may be considered as 
completed. 
There are some exceptions to the obligation to settle through the foreign exchange market which are 
described in the Argentine Foreign Exchange Regulations. 
 
Obligation to Settle Foreign Currency from Exports of Services 
Payments received for the provision of services by residents to non-residents must be entered and settled 
through the foreign exchange market within 20 business days from the date of its collection abroad or in Argentina or 
its crediting to foreign accounts. 
In the case of funds received or credited abroad, the collection and liquidation may be considered completed 
for the amount equivalent to the usual expenses debited by the financial entities abroad for the transfer of funds to the 
country. 
The aforementioned provisions of Decree No. 28/2023 are also applicable to the export of services. See “—
Entry and Settlement of the Proceeds from the Export of Goods Through the Foreign Exchange Market.” 
 
Application of Export Revenues 
The Argentine Foreign Exchange Regulations authorize the application of export revenues to the repayment 
of: (i) pre-financing of exports and export financing granted or guaranteed by local financial entities; (ii) pre-
financing of exports and export advances settled in the foreign exchange market, provided that the corresponding 
transactions have been executed through public deeds or public registries; (iii) financial indebtedness under contracts 
entered into prior to August 31, 2019 that provide for the cancellation thereof through the application abroad of export 
funds; (iv) other foreign financial indebtedness subject to certain requirements as set forth in Sections 7.9 and 7.10 of 
the Argentine Foreign Exchange Regulations; and (v) advances, pre-financing and post-financing from abroad with 
partial liquidation under the provisions of Decrees No. 492/2023, No. 549/2023, No. 597/2023 and No. 28/2023. 
Likewise, it allows keeping export revenues abroad to guarantee the payment of new indebtedness, provided certain 
requirements are met. 
 
Financial Indebtedness With Foreign Countries 
According to Section 2.4 of the Argentine Foreign Exchange Regulations for resident debtors to be able to 
access the foreign exchange market to repay financial indebtedness with foreign countries disbursed as from 
September 1, 2019, the loan proceeds must have been settled through the foreign exchange market and the transaction 
must have been declared in the External Assets and Liabilities Survey (as defined below, see “—Other Specific 
Provisions—BCRA Information Framework”). Accordingly, although settlement of the loan proceeds is not 
mandatory, failure to settle will preclude future access to the foreign exchange market for repayment purposes. 
BCRA Communication “A” 8,059 dated July 4, 2024, removed the requirement of prior conformity of the 
BCRA for access to the foreign exchange market to make interest payments on commercial debts for the import of 
goods and services with related foreign counterparties as long as the interest maturity occurs as from July 5, 2024.  
This communication also established that prior approval from the BCRA, as outlined in Sections 3.3 and 
3.5.6 of the Argentine Foreign Exchange Regulations, is not required to access the foreign exchange market for 
making interest payments on commercial debts not mentioned in the previous paragraph and on financial 
indebtedness, provided that the creditor is a related counterparty to the debtor. This is contingent upon meeting other 
applicable requirements and ensuring that the payment is made simultaneously with the settlement for an amount not 
less than the interest amount for which the foreign exchange market is accessed. This includes: (i) new financial 
indebtedness abroad with an average life of at least two years and a grace period of at least one year for the payment 
of principal, both counted from the date the market access is materialized, and (ii) new direct investment contributions 
from non-residents. 
The new financial indebtedness abroad and new foreign direct investment contributions used within this 
framework: (i) may be entered and settled by the debtor of the foreign indebtedness whose interest is being paid or by 

 
162 
 
another resident company related to the debtor and its economic group, and (ii) may not be counted for the purposes 
of other mechanisms considered in the Argentine Foreign Exchange Regulations. 
 
Specific Provisions On Access To The Foreign Exchange Market 
General Requirements 
As a general rule, and in addition to the specific rules of each transaction for access, certain general 
requirements must be complied with by a local company or individual to access the foreign exchange market for the 
purchase of foreign currency or its transfer abroad (i.e., payments of imports and other purchases of goods abroad; 
payment of services rendered by non-residents; distribution of profits and dividends; payment of principal and interest 
on foreign indebtedness; interest payments on debts for the import of goods and services, among others) without 
requiring prior approval from the BCRA. In this regard, the local company or individual must file an affidavit stating 
that: 
(1) (a) At the time of access to the foreign exchange market, all of its foreign currency holdings in Argentina 
are deposited in accounts in financial institutions, and (b) at the beginning of the day on which it requests 
access to the foreign exchange market, it does not hold Argentine certificates of deposit (“CEDEARs”) 
representing foreign shares and/or available liquid foreign assets that together have a value greater than 
US$100,000 (funds deposited abroad that constitute reserve or guarantee funds under debt contracts with 
foreign countries, or funds granted as guarantee for derivatives arranged abroad are excluded from this 
limit). If the customer is a local government, foreign currency holdings deposited with local financial 
institutions must also be accounted up to December 31, 2024. For these purposes, “liquid foreign assets” 
are considered to be holdings of banknotes and coins in foreign currency, cash in gold coins or bars of good 
delivery, demand deposits in financial institutions abroad and other investments that allow immediate 
availability of foreign currency. On the other hand, funds deposited abroad that cannot be used by the client 
because they are reserve or guarantee funds created by virtue of the requirements set forth in foreign debt 
contracts or funds created as guarantee for derivative transactions arranged abroad should not be considered 
as liquid foreign assets available. In the event that the client is a local government and exceeds the 
established limit, the institution may also accept an affidavit from the client stating that the excess was used 
to make payments for the foreign exchange market through swap and/or arbitrage operations with the 
deposited funds.  
(2) It undertakes the obligation to settle in the foreign exchange market, within five business days of its 
availability, the funds received abroad from the collection of loans granted to third parties, time deposits, or 
the sale of any type of asset, to the extent that the asset subject to the sale was acquired, the deposit 
constituted or the loan granted after May 28, 2020. 
(3) On the date of access to the foreign exchange market and in the previous 90 calendar days: (a) did not 
arrange sales in Argentina of securities with settlement in foreign currency, (b) did not exchange securities 
issued by residents for foreign assets, (c) did not transfer securities to depository entities abroad, (d) did not 
acquire in Argentina securities issued by non-residents with settlement in Argentine Pesos, (e) did not 
acquire CEDEARs representing foreign shares, (f) did not acquire securities representing private debt 
issued in foreign jurisdiction, and (g) did not deliver funds in local currency or other local assets (except 
funds in foreign currency deposited in local financial institutions) to any entity (whether physical or legal, 
resident or non-resident, related or not), receiving as prior or subsequent consideration, directly or 
indirectly, by itself or through a related, controlled or controlling entity, foreign assets, crypto-assets or 
securities deposited abroad. 
(4) It undertakes the obligation not to enter into any of the transactions described in paragraph (3) above from 
the time it requests access to the foreign exchange market and for 90 calendar days thereafter. 
(5) Section 3.16.3 of the Argentine Foreign Exchange Regulations add that, in the event that the customer 
requesting access to the exchange market is a legal entity, in order for the transaction not to be covered by 
the requirement of prior approval by the BCRA must be submitted to the corresponding financial 
institution:  

 
163 
 
(a) An affidavit evidencing that within the term provided in Section 3.16.3.4. (90 days prior to 
accessing the foreign exchange market) it has not delivered in Argentina any funds in local 
currency or other liquid local assets, except funds in foreign currency deposited in local financial 
institutions, to any person or legal entity, except those directly associated with regular 
transactions in the course of its business, or 
(b) (i) as required by Section 3.16.3.3. of the Argentine Foreign Exchange Regulations, an affidavit 
stating details of the physical or legal persons exercising a direct control relationship over the 
client and of other legal persons with which it is part of the same economic group. In determining 
the existence of a direct control relationship, the types of relationships described in Section 
1.2.2.1 of the Large Exposures Regulation should be considered. Companies sharing a control 
relationship of the type defined in Sections 1.2.1.1 and 1.2.2.1 of the Large Exposures 
Regulations should be considered as members of the same “economic group” (Economic Group 
Description Affidavit); and (ii) that on the day on which it requests access to the market and in 
the 90 days prior to that date, it has not delivered in Argentina any funds in local currency or

(a) 
Access to the foreign exchange market to make import payments for goods whose customs 
entry registration occurred up to December 12, 2023, in addition to the remaining applicable

Payment Of Foreign Debts For The Importation Of Goods and/or For Services Effectively Rendered and/or 
Accrued 
On December 22, 2023, the BCRA issued Communication “A” 7,925, requiring importers with outstanding 
debts for goods imported and services received until December 12, 2023 (“Import Debt Stock”), to subscribe to 
“Bonds for the Reconstruction of a Free Argentina” (“BOPREAL”). This requirement was subsequently incorporated 
into Section 10.11 of the Argentine Foreign Exchange Regulations, as amended by Communication “A” 8035. 
Generally, prior approval from the BCRA is required to access the foreign exchange market for the payment of the 
Import Debt Stock. However, certain exceptions are outlined in the regulations. 
 
Importers of goods may subscribe the BOPREAL for up to the amount of the outstanding debt for their 
imports of goods with customs entry registration up to and including December 12, 2023. The amount of the 
BOPREAL that importers may subscribe will be adjusted to the outstanding amount registered in the BCRA’s 
SEPAIMPO system. Importers of services accrued up to December 12, 2023, may also subscribe the BOPREAL for 
up to the amount of the outstanding debt for such transactions. Importers of goods and services that, prior to January 
31, 2024, subscribe the series offered (maturity in 2027), and for an amount equal to or greater than 50% of the 
outstanding amount of the Import Debt Stock, will be able to access the foreign exchange market as from February 1, 
2024 to pay the Import Debt Stock for the equivalent of 5% of the amount subscribed of such series. 
 
Likewise, access to the foreign exchange market is authorized for the payment of the Import Debt Stock by 
means of an exchange and/or arbitrage with the funds deposited in a local bank account and originated in collections 
of principal and interest in foreign currency of the BOPREAL. 
 
Importers subscribing to BOPREAL may sell them with settlement in foreign currency in Argentina or 
abroad or transfer them to depositories abroad, for up to the amount acquired in the primary subscription without 
limiting their ability to access the foreign exchange market. Likewise, Communication “A” 7,935 established that 
those who have subscribed BOPREAL in primary bidding may, as from April 1, 2024, carry out sales transactions of 
securities against foreign currency for the difference between the nominal value bid and the sale price in the 
secondary market obtained from the sale of the BOPREAL, without violating the sworn statements set forth in 
Sections 3.16.3.1. and 3.16.3.2. of the Argentine Foreign Exchange Regulations. 
 
In turn, through Communication “A” 8,055 dated June 28, 2024, BCRA established that if clients complete a 
sale operation with a repurchase obligation using BOPREAL acquired in primary bidding, the following conditions 
must be met: 
 
(1) The sale of securities at the origin of the transaction should not be considered for the purposes of 
preparing the affidavit provided for in Sections 3.16.3.1. and 3.16.3.2. of the Argentine Foreign Exchange 

 
167 
 
Regulations, in line with the provisions of the first paragraph of Section 4.7.2. of the Argentine Foreign 
Exchange Regulations. 
 
(2) The above-mentioned sale does not allow the client to conclude securities transactions for the difference 
between the value obtained from the sale and the nominal value of the securities. 
 
(3) Once the client has regained possession of the BOPREAL, the securities will be treated in the same way 
as those acquired in the primary offer. 
 
Payment For Services Rendered By Non-Residents 
Pursuant to Section 3.2 of the Argentine Foreign Exchange Regulations, entities may access the foreign 
exchange market to make payments for services rendered by non-residents as long as they have documentation to 
support the existence of the service. 
In the case of commercial debts for services, access is granted as from the expiration date, provided that it is 
verified that the operation is declared, if applicable, in the last due presentation of the External Assets and Liabilities 
Survey. 
Communication “A” 7,953 issued on January 26, 2024, substantially modified the regime of access to the 
foreign exchange market for the payment of imports of goods and services. Said Communication established the 
following regarding access to the foreign exchange market for the payment of imports of services, effective as of

subscribed in foreign currency, and (ii) provided that the proceeds of the issue are previously settled through the 
foreign exchange market.  
On June 28, 2024, the BCRA issued Communication “A” 8,055, thereby establishing that financial entities 
may also provide resident clients with access to the foreign exchange market with the objective of repaying the 
principal and interest on debt securities denominated in foreign currency, either in Argentina or abroad. This will be 
permitted provided that the other applicable requirements are met, and on the condition that the securities in question 
have been fully subscribed abroad and all funds received have been settled in the foreign exchange market. In the 
event that the payment must be made abroad, access to the foreign exchange market may be granted up to three 
business days before the due date of the principal and/or interest. 
It was additionally established that, in the event a sale transaction is concluded with a repurchase obligation 
through the utilization of BOPREAL bonds procured through primary bidding, there is no obligation to consider the 
sale of said securities at their origin for purposes of affidavit preparation, as outlined in Sections 3.16.3.1 and 3.16.3.2 
of the Argentine Foreign Exchange Regulations. This aligns with the stipulations of the initial paragraph of Section 
4.7.2 of said regulations. Nevertheless, this sale will not permit the client to complete transactions involving the 
securities in question, given that the proceeds from the sale will not cover the nominal value of the securities, as 
stipulated in the second paragraph of the aforementioned section. 
Once the client has regained possession of the BOPREAL bonds, the securities will receive the same 
treatment as those acquired in primary bidding. 
Access To The Foreign Exchange Market By Guarantee Trusts For The Payment Of Principal And Interest 
Pursuant to Section 3.7 of the Argentine Foreign Exchange Regulations, Argentine guarantee trusts created 
to guarantee principal and interest payments of resident debtors may access the foreign exchange market to make such 
payments at their scheduled maturity, to the extent that, in accordance with the applicable regulations in force, the 
debtor would have had access to the foreign exchange market to make such payments directly. Also, under certain 
conditions, a trustee may access the foreign exchange market to guarantee certain principal and interest payments on 
foreign financial debt and anticipate access to the foreign exchange market. 
 
Profit And Dividend Payment  
Pursuant to Section 3.4 of the Argentine Foreign Exchange Regulations, access to the foreign exchange 
market for the transfer of foreign currency abroad for the payment of dividends and profits to non-resident 
shareholders is subject to the prior approval of the BCRA, unless the following requirements are met: 
(i) Dividends must correspond to closed and audited balance sheets. 
 
(ii) The total amount paid to non-resident shareholders shall not exceed the amount in Argentine Pesos that 
correspond according to the distribution determined by the shareholders’ meeting. 
 
(iii) If applicable, the External Assets and Liabilities Survey must have been complied with for the 
transactions involved. 
 
(iv) The company falls within one of the following situations and fulfills all the conditions stipulated in 
each case: 
 
(a) Records direct investment contributions settled as of January 17, 2020. In which case, (i) the 
total amount of transfers made in the foreign exchange market for the payment of dividends 
to non-resident shareholders may not exceed 30% of the total value of the capital 
contributions made in the relevant local company that have entered and been settled through 
the foreign exchange market as of January 17, 2020, (ii) access will only be granted after 
the expiration of a term of not less than 30 calendar days as from the settlement date of the 
last capital contribution taken into account to determine the aforementioned 30% capital 

 
172 
 
cap, and (iii) the definitive capitalization of the capital contributions must be accredited or, 
failing that, the filing of the registration procedure of the capital contribution with the Public 
Registry must be evidenced. In this case, the accreditation of the definitive capitalization 
must be made within 365 calendar days following the date of the initial filing with the 
Public Registry. 
(b) Profits generated in projects under the Plan GasAr 2020-2024. In this case, (i) the profits 
generated by the foreign direct investment contributions entered and settled through the 
foreign exchange market as from November 16, 2020, destined to the financing of projects 
framed within the Plan GasAr 2020-2024. If the client is a direct beneficiary of Decree No. 
277/2022, the value of the benefits of the decree used by the client, directly or indirectly, 
shall be deducted from the amount allowed in the preceding paragraph, (ii) the access to the 
foreign exchange market occurs no earlier than two years from the date of settlement in the 
foreign exchange market of the contribution that allows the framing in this section, and (iii) 
the client must submit the documentation supporting the definitive capitalization of the 
contribution. 
(c) The client must have a Certification of Increased Exports of Goods for the years 2021 to 
2023, issued in accordance with Section 3.18 of the Argentine Foreign Exchange 
Regulations, for the equivalent value of the profits and dividends being paid. 
(d) It has certification under the foreign exchange access regimes for incremental production of 
oil and/or natural gas. 
(e) The client engages in an exchange and/or arbitration transaction with funds deposited in a 
local account and originating from collections in foreign currency of principal or interest on 
BOPREAL. 
Cases that do not comply with the above conditions will require the prior approval of the BCRA to access the 
foreign exchange market for the purchase of foreign currency for the distribution of profits and dividends. 
On April 30, 2024, the BCRA established, via Communication “A” 7,999, that clients may subscribe to 
BOPREAL for an amount equivalent to the profits and dividends pending payment to non-resident shareholders, in 
accordance with the distribution determined by the shareholders’ meeting, in local currency. It is the responsibility of 
the entity completing the subscription on behalf of the client to verify compliance with the established requirements. 
Moreover, clients may access the foreign exchange market for the payment of profits and dividends, 
provided that the applicable requirements are met, by carrying out an exchange and/or arbitration with funds 
deposited in a local account and originating from collections of principal and interest in foreign currency of 
BOPREAL. 
In addition, with regard to the profits and dividends accrued in Argentine Pesos within Argentina by non-
residents from September 1, 2019, and which have not been remitted abroad, it was established, among other things, 
that non-resident clients may subscribe to BOPREAL. BOPREAL may be subscribed for up to the equivalent amount 
in local currency of the profits and dividends collected from September 1, 2019, according to the distribution 
determined by the shareholders’ meeting, adjusted by the latest available CPI published by the INDEC at the 
subscription date. The entity that completes the subscription offer on behalf of the client must have documentation 
that supports and verifies compliance with the indicated conditions. 
 
Other Specific Provisions 
Securities Transactions 
According to CNV General Resolution No. 988/2023, sales of marketable securities with settlement in 
foreign currency, in any jurisdiction and regardless of the law under which they are issued may be made, provided 
that a minimum holding period of one business day counted as of its accreditation at the Central Depository Agent of 
Negotiable Securities (Agente Depositario Central de Valores Negociables), to the extent that the purchases of the 
marketable securities in question have been made against Argentine Pesos. 

 
173 
 
Likewise, transfers to foreign depository institutions of marketable securities purchased with Argentine 
Pesos, regardless of the law under which they are issued, must comply with a minimum holding period of one 
business day as from the date of deposit of such marketable securities, unless such accreditation (i) results from a 
primary placement of marketable securities issued by the Argentine National Treasury or by the BCRA, in the 
framework of the Communication “A” 7,918, as amended, (ii) or refers to CEDEARs traded in markets regulated by 
the CNV. Intermediaries and trading agents must verify compliance with the aforementioned minimum holding 
period of marketable securities. 
It should be noted that the aforementioned provisions do not extend to transfers of securities to foreign 
depositary entities made by the client for the purpose of participating in a debt securities exchange issued by the 
Argentine government, local governments, or resident private sector issuers. The client is required to present the 
relevant certification for the exchanged debt securities.  
In accordance with the prevailing CNV regulations, local brokers are obliged to comply with the following 
requirements prior to executing or registering any of the aforementioned securities transactions in CNV-authorized 
markets: 
(a) In the event that the trade is to be performed by non-resident clients that do not qualify as foreign 
brokers, it is the responsibility of the broker to ensure that the trades are for the account of the client and 
financed with the client’s own funds. Furthermore, the broker must ensure that the trades do not exceed 
Ps.200 million per day. 
 
(b) In the event that the trade is to be performed by non-resident clients that qualify as foreign brokers, 
whether acting for their own account or on behalf of Argentine clients, it is the responsibility of the 
broker to ensure that the trades do not exceed Ps.200 million per client per day. In the event that a 
foreign broker is acting in the capacity of a depositary for shares issued by a local issuer and is 
undertaking the trade for the purpose of distributing dividends to holders of ADRs, GDRs, or analogous 
certificates held in custody abroad, said broker shall not be subject to the aforementioned requirement. 
 
(c) In the event that the trade is to be performed by resident clients acting for their own portfolio and 
financed with their own funds, the above-mentioned daily trading limit does not apply. 
 
The aforementioned trade restrictions do not apply to BOPREAL acquired in primary bidding and to the sale 
of securities with settlement in foreign currency and in the local jurisdiction previously acquired in Argentine Pesos 
by individual or corporate resident clients with funds from UVA mortgage loans. These clients must be granted the 
funds by financial entities authorized to act as such under terms of Law No. 21.526. Furthermore, the proceeds from 
these sales must be applied to the purchase of real estate in Argentina within the framework of the aforementioned 
credits.  
Communication “A” 8,099 
Communication “A” 8,099 of the BCRA establishes the regulations pertaining to the foreign exchange 
benefits for Single Project Vehicles (“VPU,” the Spanish acronym for such) that have adhered to the RIGI. The 
BCRA has established: 
(i) exceptions to the mandatory inflow and settlement of export proceeds in foreign currency made by 
a VPU adhering to the RIGI.  
(ii) exceptions to the mandatory inflow and settlement of foreign currency arising from export of 
services.  
(iii) access to the foreign exchange market to make payments of certain expenses;  
(iv) access to the foreign exchange market to make payments of dividends to non-resident shareholders 
(v) application abroad of proceeds from exports of goods; and  
(vi) exchange stability applicable to the VPU on the date of adherence to the RIGI.  

 
174 
 
BCRA Information Framework 
On December 28, 2017, the BCRA replaced the information regimes established in Communications “A” 
3,602 and “A” 4,237 with Communication “A” 6,401 (and the complementary Communication “A” 6,795), a unified 
framework applicable from December 31, 2017 (“External Assets and Liabilities Survey”) (Relevamiento de Activos y 
Pasivos Externos). The reporting requirements under the information regime are contingent upon the final balance of 
foreign assets and liabilities: 
• 
For individuals or entities whose balance, acquisition, or sale of external assets and liabilities at the end of a 
given calendar year is equal to or exceeds the equivalent of US$50 million, a quarterly declaration prior to 
the end of each quarter and an annual declaration, which permits the correction, affirmation, or update of 
quarterly declarations, must be filed. 
• 
For individuals or entities whose balance, acquisition, or sale of external assets and liabilities at the 
conclusion of a given calendar year exceeds US$10 million but does not exceed US$50 million, an annual 
declaration is the sole requisite form of compliance. 
• 
For individuals or entities whose balance, acquisition, or sale of external assets and liabilities at the 
conclusion of a specified calendar year exceeds US$1 million but does not exceed US$10 million, a 
streamlined annual declaration is the sole requisite documentation. 
Individuals or entities for whom the balance or acquisition or sale of foreign assets and liabilities at the end 
of a given calendar year is less than US$1 million are exempt from reporting obligations. 
Access to the foreign exchange market for the repayment of foreign financial debt and other operations is 
contingent upon the debtor’s compliance with the External Assets and Liabilities Survey. See “—Specific Provisions 
on Access to the Foreign Exchange Market—External Financial Indebtedness.” 
 
Advance Notice of Foreign Exchange Operations 
Entities authorized to operate with foreign currency are obliged to provide the BCRA with information on 
outgoing operations through the Foreign Exchange Market for daily amounts equal to or greater than the equivalent of 
US$10,000. This information must be provided at the end of each business day and with two business days’ notice. 
Clients are obliged to inform financial entities in advance, so that they can comply with the requirements of this 
information regime. Consequently, as long as the other requirements established in the Argentine Foreign Exchange 
Regulations are simultaneously met, they can process foreign exchange transactions. 
On August 8, 2024, the BCRA issued Communication “A” 8,085, which established that from August 14, 
2024, the daily amount from which compliance with this information regime will be required as a prerequisite for 
access to the foreign exchange market will be increased to the equivalent of US$100,000. Furthermore, the document 
indicated that as of August 9, 2024, the “Foreign Exchange Information Registry for Exporters and Importers of 
Goods,” as outlined in Section 3.16.5 of the Argentine Foreign Exchange Regulations, will be revoked. 
 
Argentine Criminal Foreign Exchange Regulations 
The Argentine Foreign Exchange Regulations establish that transactions that do not comply with the exchange 
regulations established by the Argentine Foreign Exchange Regulations will be subject to the Criminal Argentine 
Foreign Exchange Regulations (Law No. 19,359 and amendments). 
For further information on the exchange control restrictions and regulations in force, you should consult your 
legal advisors and read the applicable rules mentioned in this document, as well as their amendments and 
complementary regulations, which are available on the website: http://www.infoleg.gob.ar/ or on the BCRA’s website: 
https://www.bcra.gob.ar/, as applicable. The information contained in these websites is not part of this annual report 
and is not deemed to be incorporated herein.

TAXATION 
Mexican Tax Considerations 
General  
The following summary of the Mexican federal income tax consequences of the purchase, ownership and 
disposition of our series A shares or ADSs, is based upon the federal tax laws of Mexico as in effect on the date of 
this annual report, which are subject to change. Mexico has also entered into and is negotiating several tax treaties 
with other countries, that may have an impact on the tax treatment of the purchase, ownership and disposition of our 
series A shares or ADSs.  
This summary is not a comprehensive discussion of all the tax considerations that may be relevant to a 
particular investor’s decision to purchase, hold, or dispose of series A shares or ADSs. In particular, this summary is 
directed only to Non-Mexican Holders that acquired our series A shares or ADS and does not address tax 
consequences to Holders that are regarded as residents of Mexico for tax purposes, Holders who may be subject to 
special tax rules, such as tax exempt entities, entities or arrangements that are treated as disregarded for Mexican or 
other jurisdictions’ income tax purposes, persons or group of persons under the Mexican Securities Market Law that 
own or are treated as owning, either, 10% or more of our stock by vote or value, or the control of our Company, or 
persons owning our shares before they were originally registered in the RNV maintained by the CNBV. Moreover, 
this summary does not address the applicable tax treatment in Mexico for transactions not conducted through an 
authorized Mexican or international recognized stock markets, nor through registered or protected transactions.  
For purposes of this summary, an “International Holder” is the holder of our series A shares or ADSs that (i) 
is not regarded as resident of Mexico under current domestic tax laws, and (ii) is not a non-Mexican resident with a 
permanent establishment in Mexico for tax purposes.  
You should consult your own tax advisors about the consequences of the acquisition, ownership, and 
disposition of the series A shares or ADSs, including the relevance to your particular situation of the 
considerations discussed below and any consequences arising under foreign, state, local or other tax laws.  
This description assumes that you are an ADS holder. If you hold the ADSs indirectly, you must rely 
on the procedures of your broker or other financial institution to assert the rights of ADS holders described in 
this section. You should consult with your broker or financial institution to find out about those procedures.  
ADSs  
In accordance with provisions of the current Administrative Tax Regulations ADSs would be regarded as 
securities that exclusively represent our series A shares which are registered in the RNV maintained by the CNBV; 
therefore, should be treated as placed among the investing public at large (colocadas entre el gran público 
inversionista.) 
Taxation of Dividends  
Gross amount of any distribution of cash or property with respect to our series A shares or ADSs that is paid 
out of our current or accumulated earnings and profits would be subject to a 10% withholding income tax which 
would be withheld by the Mexican custodian in INDEVAL. Withholding tax would be computed on the Mexican 
Peso denominated amount distributed as dividend.  
Mexican custodians in INDEVAL are obliged to issue tax receipts for taxes withheld on dividend 
distributions, which should be issued under the name of the depositary in case of ADSs or brokers where International 
Holders maintain their global accounts to hold our series A shares.  
The 10% withholding tax rate may be reduced under certain tax treaties entered by Mexico with other 
countries, if formal requirements are complied with and disclosure is made to the Mexican custodian by the 
depositary or the broker with respect to the effective beneficiary of the dividend income. A 5% withholding tax rate 
may apply for International Holders that are U.S. companies that are resident for tax purposes in the U.S. and that are 

 
176 
 
entitled to access U.S.-Mexico Tax Treaty benefits, to the extent such International Holders that are U.S. companies 
own 10% or more of the voting shares of the Company.  
Taxation of Dispositions of series A shares or ADSs  
The sale or the disposition of series A shares carried out through a Mexican authorized stock exchange 
market (e.g., Bolsa Mexicana de Valores or Bolsa Institucional de Valores) would be exempt from Mexican income 
tax, as long as the International Holder furnishes an affidavit to its Mexican financial intermediary, stating, under 
oath, that it is a resident for tax purposes in a country with which Mexico has an income tax treaty in force and 
provides its tax identification number; otherwise, the Mexican financial intermediary should withhold 10% tax on the 
capital gain derived from the transaction.  
Considering that our series A shares underlying the ADSs are registered with the RNV, the sale or 
disposition of ADSs would not be subject to Mexican income tax if (i) the transaction is carried out through NYSE or 
other recognized markets as defined in the Mexican Federal Tax Code, and (ii) the International Holder is a tax 
resident of a country with which Mexico has in force a treaty for the avoidance of double taxation.  
Deposits and withdrawals of series A shares by International Holders in exchange for ADSs and the 
surrender of ADRs to the depositary for exchanging ADRs for uncertificated ADSs should not result in the realization 
of gain or loss for Mexican income tax purposes.  
In the event that the sale or the disposition of series A shares were to be carried out other than through a 
Mexican authorized stock exchange market (e.g., Bolsa Mexicana de Valores or Bolsa Institucional de Valores) such 
disposition should be subject to a 25% Mexican income tax on the gross proceeds derived from the transaction which 
should be directly paid by the International Holder before the Mexican tax authorities within the subsequent 15-
business days after the transaction is conducted. Alternatively, if formal requirements are complied with, International 
Holders could elect to compute its tax liability with the 35% income tax on the capital gain. International Holders that 
are residents of countries with which Mexico has a tax treaty in force may be entitled to benefits that would reduce or 
eliminate Mexican taxes imposed on the sale or disposition of series A shares if formal requirements are complied 
with.  
Value Added Tax  
Dividend distributions, the purchase and the sale or disposition of the series A shares or ADSs are exempt of 
Value Added Tax.  
Tax impact of the Labor Reform 
Mexican tax provisions prohibit the tax deduction of payments related to services companies under the 
concept of subcontracting or outsourcing, or specialized services from contractors that do not have the authorization 
from the Mexican Ministry of Labor and Social Welfare. Specialized services cannot (a) include activities equal or 
similar to the activities performed by the employees of the contracting party, or (b) cover the main economic activity 
of the contracting party.  
Payments or consideration made for the subcontracting of personnel will not be considered as strictly 
necessary expenses, therefore, they will not be deductible for income tax purposes, nor creditable for value added tax. 
In addition, the tax provisions disallow any tax effects to the specialized services paid when they are carried out by 
the provider’s personnel that originally used to be employed by the beneficiary and were transferred by any legal 
means from the service provider to the beneficiary. 
Note that pursuant to the labor reform, for Mexican entities to deduct payments for subcontracting 
specialized services, and credit the VAT related to such payments, the Mexican entity requires to receive certain 
documentation from the specialized service provider. Under the terms of the labor reform, the tax authorities may 
impose fines ranging from approximately US$10,250 to US$20,550 to the specialized service providers that fail to 
deliver the documentation for each obligation to deliver information not complied with. Furthermore, the labor reform 

 
177 
 
establishes that Mexican entities subcontracting personnel will be joint and severally liable with the contracting party 
for the employment-related taxes triggered by the employees associated to the services or works rendered.  
Also, using deceptive practices to conceal the provision of subcontracting personnel would constitute tax 
fraud. 
Other Mexican Taxes  
There are currently no Mexican estate, gift, stamp, registration, or similar taxes payable with respect to the 
purchase, ownership or disposition of our series A shares or ADSs. The inheritance of our series A shares or ADSs 
received by a non-Mexican resident would be subject to income tax at the rate of 25% on the fair-market-value of the 
series A shares or ADSs inherited.  
 
United States Federal Income Tax Considerations 
The following is a summary of material U.S. federal income tax considerations that are likely to be relevant 
to the purchase, ownership and disposition of our series A shares or ADSs by a U.S. Holder (as defined below).  
This summary is based on provisions of the Internal Revenue Code of 1986, as amended (“Code”), and 
regulations, rulings and judicial interpretations thereof, in force as of the date thereof, and the Convention Between 
the Government of the United States of America and the Government of the United Mexican States for the Avoidance 
of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income dated September 18, 1992 
(as amended by any subsequent protocols) (“U.S.-Mexico Tax Treaty”). Those authorities may be changed at any 
time, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those summarized 
below.  
This summary is not a comprehensive discussion of all of the tax considerations that may be relevant to a 
particular investor’s decision to purchase, hold, or dispose of series A shares or ADSs. In particular, this summary is 
directed only to U.S. Holders that hold series A shares or ADSs as capital assets and does not address tax 
consequences to U.S. Holders who may be subject to special tax rules, such as banks, brokers or dealers in securities 
or currencies, traders in securities electing to mark to market, financial institutions, life insurance companies, tax 
exempt entities, entities or arrangements that are treated as partnerships for U.S. federal income tax purposes (or 
partners therein), holders that own or are treated as owning 10% or more of our stock by vote or value, persons 
holding series A shares or ADSs as part of a hedging or conversion transaction or a straddle, or persons whose 
functional currency is not the U.S. Dollar. Moreover, this summary does not address state, local or foreign taxes, the 
U.S. federal estate and gift taxes, or the Medicare contribution tax applicable to net investment income of certain non-
corporate U.S. Holders, or alternative minimum tax consequences of acquiring, holding or disposing of series A 
shares or ADSs.  
For purposes of this summary, a “U.S. Holder” is a beneficial owner of series A shares or ADSs that is 
(1) (a) a citizen or resident of the United States, (b) a U.S. domestic corporation or (c) otherwise subject to U.S. 
federal income taxation on a net income basis in respect of such series A shares or ADSs and (2) fully eligible for 
benefits under the U.S.-Mexico Tax Treaty.  
You should consult your own tax advisors about the consequences of the acquisition, ownership, and 
disposition of the series A shares or ADSs, including the relevance to your particular situation of the 
considerations discussed below and any consequences arising under foreign, state, local or other tax laws.  
ADSs  
In general, if you are a U.S. Holder of ADSs, you will be treated, for U.S. federal income tax purposes, as 
the beneficial owner of the underlying series A shares that are represented by those ADSs.  

 
178 
 
Taxation of Dividends  
Subject to the discussion below under “—Passive Foreign Investment Company Status,” the gross amount of 
any distribution of cash or property with respect to our series A shares or ADSs (including any amount withheld in 
respect of Mexican withholding taxes) that is paid out of our current or accumulated earnings and profits (as 
determined for United States federal income tax purposes) will generally be includible in your taxable income as 
ordinary dividend income on the day on which you receive the dividend, in the case of series A shares, or the date the 
depositary receives the dividends, in the case of ADSs, and will not be eligible for the dividends-received deduction 
allowed to corporations under the Code.  
We do not expect to maintain calculations of our earnings and profits in accordance with U.S. federal income 
tax principles. U.S. Holders therefore should expect that distributions generally will be treated as dividends for U.S. 
federal income tax purposes.  
If you are a U.S. Holder, dividends paid in a currency other than U.S. Dollars generally will be includible in 
your income in a U.S. Dollar amount calculated by reference to the exchange rate in effect on the day you receive the 
dividends, in the case of series A shares, or the date the depositary receives the dividends, in the case of series A 
shares represented by ADSs. Any gain or loss on a subsequent sale, conversion or other disposition of such non-U.S. 
currency by such U.S. Holder generally will be treated as ordinary income or loss and generally will be income or loss 
from sources within the United States. A U.S. Holder should consult its own tax advisors regarding the treatment of 
any foreign currency gain or loss realized with respect to any currency received as a dividend on the series A shares.  
The U.S. Dollar amount of dividends received by an individual with respect to the series A shares or ADSs 
will be subject to taxation at a preferential rate if the dividends are “qualified dividends.” Subject to certain exceptions 
for short-term positions, dividends paid on the series A shares or ADSs will be treated as qualified dividends if:  
• 
the series A shares or ADSs are readily tradable on an established securities market in the United 
States, or we are eligible for the benefits of a comprehensive tax treaty with the United States that 
the U.S. Treasury determines is satisfactory for purposes of this provision and that includes an 
exchange of information program; and  
• 
we were not, in the year prior to the year in which the dividend was paid, and are not, in the year in 
which the dividend is paid, a passive foreign investment company (a “PFIC”).  
The ADSs are listed on the NYSE, and will qualify as readily tradable on an established securities market in 
the United States so long as they are so listed. In addition, the U.S. Treasury has determined that the U.S.-Mexico Tax 
Treaty meets the requirements for reduced rates of taxation, and we believe we are eligible for the benefits of the 
U.S.-Mexico Tax Treaty. Based on our financial statements and our current expectations regarding the value and 
nature of our assets and the sources and nature of our income, we do not believe that we were a PFIC for our 2024 or 
2023 taxable years, and we do not anticipate becoming a PFIC for our current taxable year or in the foreseeable 
future. Holders should consult their own tax advisors regarding the availability of the reduced dividend tax rate in 
light of their own particular circumstances.  
Subject to generally applicable limitations and conditions, Mexican withholding tax on dividends paid at the 
appropriate rate applicable to the U.S. Holder may be eligible for a credit against such U.S. Holder’s U.S. federal 
income tax liability. These generally applicable limitations and conditions include requirements adopted by the U.S. 
Internal Revenue Service (“IRS”) in regulations promulgated in December 2021, and any Mexican tax will need to 
satisfy these requirements in order to be eligible to be a creditable tax for a U.S. Holder. In the case of a U.S. Holder 
that is either (i) eligible for, and properly elects, the benefits of the U.S.-Mexico Tax Treaty, or (ii) consistently elects 
to apply a modified version of these rules under temporary guidance issued in 2023 and complies with specific 
requirements set forth in such guidance, the Mexican tax on dividends will be treated as meeting the new 
requirements and therefore as a creditable tax. In the case of all other U.S. Holders, the application of these 
requirements to the Mexican tax on dividends is uncertain, and we have not determined whether these requirements 
have been met. If the Mexican tax on dividends is not a creditable tax for a U.S. Holder or the U.S. Holder does not 
elect to claim a foreign tax credit for any foreign income taxes paid or accrued in the same taxable year, the U.S. 
Holder may be able to deduct the Mexican tax in computing such U.S. Holder’s taxable income for U.S. federal 
income tax purposes. Dividend distributions with respect to our series A shares or ADSs will constitute income from 

 
179 
 
sources without the United States and, for U.S. Holders that elect to claim foreign tax credits, generally will constitute 
“passive category income” for foreign tax credit purposes.  
The availability and calculation of foreign tax credits and deductions for foreign taxes depend on a U.S. 
Holder’s particular circumstances and involve the application of complex rules to those circumstances. The temporary 
guidance discussed above also indicates that the Treasury and the IRS are considering proposing amendments to the 
December 2021 regulations and that the temporary guidance can be relied upon until additional guidance is issued 
that withdraws or modifies the temporary guidance. U.S. Holders should consult their own tax advisors regarding the 
application of these rules to their particular situations.  
U.S. Holders that receive distributions of additional series A shares or ADSs or rights to subscribe for series 
A shares or ADSs as part of a pro rata distribution to all our shareholders generally will not be subject to U.S. federal 
income tax in respect of the distributions, unless any holder of our shares or ADSs has the right to receive cash or 
property instead, in which case the U.S. Holder will generally be treated as if it received cash equal to the fair market 
value of the distribution.  
Taxation of Dispositions of series A shares or ADSs  
Subject to the discussion below under “—Passive Foreign Investment Company Status,” upon a sale, 
exchange or other disposition of the series A shares or ADSs, U.S. Holders will realize capital gain or loss for U.S. 
federal income tax purposes in an amount equal to the difference between the U.S. Dollar value of the amount 
realized on the disposition and the U.S. Holder’s tax basis, determined in U.S. Dollars, in the series A shares or 
ADSs. Such gain or loss generally will be long-term capital gain or loss if the ADS or series A shares have been held 
for more than one year. Long-term capital gain realized by a U.S. Holder that is an individual generally is subject to 
taxation at a preferential rate. The deductibility of capital losses is subject to limitations.  
A U.S. Holder generally will not be entitled to credit any Mexican or Argentine tax imposed on the sale or 
other disposition of the series A shares or ADSs against such U.S. Holder’s U.S. federal income tax liability, except 
in the case of a U.S. Holder that consistently elects to apply a modified version of the U.S. foreign tax credit rules that 
is permitted under temporary guidance issued in 2023 and complies with the specific requirements set forth in such 
guidance. Additionally, capital gain or loss recognized by a U.S. Holder on the sale or other disposition of the series 
A shares or ADSs generally will be U.S. source gain or loss for U.S. foreign tax credit purposes. Consequently, even 
if the withholding tax qualifies as a creditable tax for U.S. foreign tax credit purposes, a U.S. Holder may not be able 
to credit the tax against its U.S. federal income tax liability unless such credit can be applied (subject to generally 
applicable conditions and limitations) against tax due on other income treated as derived from foreign sources. If the 
Mexican or Argentine tax is not a creditable tax, the tax would reduce the amount realized on the sale or other 
disposition of the series A shares or ADSs even if the U.S. Holder has elected to claim a foreign tax credit for other 
taxes in the same year. The temporary guidance discussed above also indicates that the Treasury and the IRS are 
considering proposing amendments to the December 2021 regulations and that the temporary guidance can be relied 
upon until additional guidance is issued that withdraws or modifies the temporary guidance. U.S. Holders should 
consult their own tax advisors regarding the application of the foreign tax credit rules to a sale or other disposition of 
the series A shares or ADSs and any Mexican or Argentine tax imposed on such sale or disposition.  
If a U.S. Holder sells or otherwise disposes of our series A shares or ADSs in exchange for currency other 
than U.S. Dollars, the amount realized generally will be the U.S. Dollar value of the currency received at the spot rate 
on the date of sale or other disposition (or, if the shares are traded on an established securities market at such time, in 
the case of cash basis and electing accrual basis U.S. Holders, the settlement date). An accrual basis U.S. Holder that 
does not elect to determine the amount realized using the spot exchange rate on the settlement date will recognize 
foreign currency gain or loss equal to the difference between the U.S. Dollar value of the amount received based on 
the spot exchange rates in effect on the date of the sale or other disposition and the settlement date. A U.S. Holder 
will generally have a tax basis in the currency received equal to the U.S. Dollar value of the currency received at the 
spot rate on the settlement date. Any currency gain or loss realized on the settlement date or the subsequent sale, 
conversion, or other disposition of the non-U.S. currency received for a different U.S. Dollar amount generally will be 
U.S.-source ordinary income or loss, and will not be eligible for the reduced tax rate applicable to long-term capital 
gains. If an accrual basis U.S. Holder makes the election described in the first sentence of this paragraph, it must be 
applied consistently from year to year and cannot be revoked without the consent of the IRS. A U.S. Holder should 

 
180 
 
consult its own tax advisors regarding the treatment of any foreign currency gain or loss realized with respect to any 
currency received in a sale or other disposition of the series A shares or ADSs.  
Deposits and withdrawals of series A shares by U.S. Holders in exchange for ADSs will not result in the 
realization of gain or loss for U.S. federal income tax purposes.  
Passive Foreign Investment Company Status  
Special U.S. tax rules apply to investors in companies that are considered to be PFICs. We will be classified 
as a PFIC in a particular taxable year if, taking into account our proportionate share of the income and assets of our 
subsidiaries under applicable “look-through” rules, either  
• 
75% or more of our gross income for the taxable year is passive income; or  
• 
the average percentage of the value of our assets that produce or are held for the production of 
passive income is at least 50%.  
For this purpose, passive income generally includes dividends, interest, gains from certain commodities 
transactions, rents, royalties and the excess of gains over losses from the disposition of assets that produce passive 
income.  
Based on our financial statements and our current expectations regarding the value and nature of our assets 
and the sources and nature of our income, we do not believe that we were a PFIC for our 2024 or 2023 taxable years, 
and we do not anticipate becoming a PFIC for our current taxable year or in the foreseeable future. However, the 
determination whether we are a PFIC must be made annually based on the facts and circumstances at that time. 
Accordingly, we cannot be certain that we will not be a PFIC for the current year or future years. If we are classified 
as a PFIC, you will generally be subject to a special tax at ordinary income tax rates on “excess distributions” 
(generally, any distributions that you receive in a taxable year that are greater than 125% of the average annual 
distributions that you have received in the preceding three taxable years, or your holding period, if shorter), and gains 
that you recognize on the disposition of your series A shares or ADSs. Under these rules (a) the excess distributions 
or gains will be allocated ratably over your holding period, (b) the amount allocated to the current taxable year and 
any taxable year prior to the first taxable year in which we are a PFIC will be taxed as ordinary income, and (c) the 
amount allocated to each of the other taxable years will be subject to tax at the highest rate of tax in effect for the 
applicable class of taxpayer for that year, and an interest charge for the deemed deferral benefit will be imposed with 
respect to the resulting tax attributable to each such other taxable year. Classification as a PFIC may also have other 
adverse tax consequences, including, in the case of individuals, the denial of a step-up in the basis of your series A 
shares or ADSs at death.  
If you are a U.S. Holder that owns an equity interest in a PFIC, you generally must annually file IRS Form 
8621, and may be required to file other IRS forms. A failure to file one or more of these forms as required may toll 
the running of the statute of limitations in respect of each of your taxable years for which such form is required to be 
filed. As a result, the taxable years with respect to which you fail to file the form may remain open to assessment by 
the IRS indefinitely, until the form is filed.  
You should consult your own tax advisor regarding the U.S. federal income tax considerations discussed 
above and the consequences to you if we are treated as a PFIC.  
Foreign Financial Asset Reporting.  
Individual U.S. Holders that own “specified foreign financial assets” with an aggregate value in excess of 
US$50,000 on the last day of the taxable year, or US$75,000 at any time during the taxable year, are generally 
required to file an information statement along with their tax returns, currently on Form 8938, with respect to such 
assets. “Specified foreign financial assets” include any financial accounts held at a non-U.S. financial institution, as 
well as securities issued by a non-U.S. issuer that are not held in accounts maintained by financial institutions. Higher 
reporting thresholds apply to certain individuals living abroad and to certain married individuals. Regulations extend 
this reporting requirement to certain entities that are treated as formed or availed of to hold direct or indirect interests 
in “specified foreign financial assets” based on objective criteria. U.S. Holders who fail to report the required 
information could be subject to substantial penalties. In addition, the statute of limitations for assessment of tax would 

 
181 
 
be suspended, in whole or part. Prospective investors are encouraged to consult with their own tax advisors regarding 
the possible application of these rules, including the application of the rules to their particular circumstances.  
Backup Withholding and Information Reporting  
Dividends paid on, and proceeds from the sale or other disposition of, the series A shares or ADSs to a U.S. 
Holder generally may be subject to the information reporting requirements of the Code and may be subject to backup 
withholding unless the U.S. Holder provides an accurate taxpayer identification number and makes any other required 
certification or otherwise establishes an exemption. Backup withholding is not an additional tax. The amount of any 
backup withholding from a payment to a U.S. Holder will be allowed as a refund or credit against the U.S. Holder’s 
U.S. federal income tax liability, provided the required information is furnished to the IRS in a timely manner.  
A holder that is not a “United States person” (as defined in the Code) may be required to comply with 
certification and identification procedures in order to establish its exemption from information reporting and backup 
withholding.  
 
Argentine Tax Considerations 
The Argentine Income Tax Law (“ITL”) imposes a capital gains tax on the sale or, transfer or any other act 
of disposition by non-Argentine residents of shares or other participations in foreign entities when the following two 
conditions are simultaneously met: (i) 30% or more of the market value of the shares, stakes, quotas, securities, or 
other kind of participations that the seller holds in the foreign entity is, at the time of the sale or at any time during the 
12 months prior to the sale, derived from attributable to assets located in Argentina owned directly or indirectly by the 
foreign entity, and (ii) the participation being transferred represents (at the time of the sale or transfer or during the 12 
prior months) at least 10% or more of the equity of the foreign entity. In this line, Argentine regulations foresee that, 
in certain cases, shares sold by related persons must be aggregated for this purpose). The applicable tax rate would 
generally be 15% (calculated on the actual net gain or a presumed net gain equal to 90% of the sale price to the extent, 
in both cases, the seller does not reside in non-cooperative jurisdictions, or the invested funds do not come from non- 
cooperative jurisdictions) of the proportional value that corresponds to the Argentine assets. This tax on indirect 
transfers only applies to participations in foreign entities acquired after the effective date of the tax reform, in force 
from January 1, 2018. Additionally, this capital gains tax shall not apply if the transfer is made within the same 
economic group in the terms established by the regulatory decree of the ITL. 
Since our Argentine assets currently represent more than 30% of the value of our total assets on a 
consolidated basis, a holder that sells or transfers our common shares, acquired after January 1, 2018, could be subject 
to the Argentine capital gains tax to the extent the mentioned requisites are met.  
Argentine holders are encouraged to consult a tax advisor as to the Argentine tax consequences derived from 
the holding of, and any transactions relating to, the ADSs and series A shares.

 QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 
Our activities are exposed to market risk, including the exchange rate risk, the interest rate risk and the price 
risk. Financial risks are those derived from financial instruments we are exposed to during or at the closing of each 
fiscal year. Risk management systems and policies are reviewed on a regular basis to reflect changes in market 
conditions and our activities, with a focus not placed on the individual risks of the business units’ operations, but with 
a wider perspective focused on monitoring risks affecting the whole portfolio. Financial risk management is 

 
182 
 
controlled by the Financial Department, which identifies, evaluates and covers financial risks. Our risk management 
strategy seeks to achieve a balance between profitability targets and risk exposure levels.

ITEM 12. 
DESCRIPTION OF SECURITIES OTHER THAN EQUITY SECURITIES 
American Depositary Shares 
The Bank of New York Mellon is the depositary of the ADS program. Each ADS represents one series A 
share (or a right to receive one series A share) deposited with Banco S3 Caceis México, S.A., Institución de Banca 
Múltiple, as custodian for the depositary in Mexico. The depositary’s office at which the ADSs will be administered, 
and its principal executive office are located at 240 Greenwich Street, New York, New York 10286. 
ADS holders may be unable to exercise voting rights with respect to the shares underlying the ADSs at our 
shareholders’ meetings, and preemptive rights may be unavailable to non-Mexican holders of ADSs. Mexican law 
governs shareholder rights. The depositary will be the holder of the series A shares underlying the ADSs. Registered 
holders of ADSs, have ADS holder rights. A deposit agreement among us, the depositary, ADS holders, and all other 
persons indirectly holding or beneficially owning ADSs sets out ADS holder rights as well as the rights and 
obligations of the depositary. New York law governs the deposit agreement and the ADSs. To exercise any 
shareholder rights directly, ADSs holders need to surrender their ADSs to become a direct shareholder. 
Depositary Fees and Expenses 
Persons depositing or withdrawing shares or ADS holders must pay: 
For: 
US$5.00 (or less) per 100 ADSs (or portion of 100 ADSs) 
Issuance of ADSs, including issuances resulting from a distribution of 
shares or rights or other property 
  
Cancellation of ADSs for the purpose of withdrawal, including if the 
deposit agreement terminates 
 
US$0.05 (or less) per ADS 
Any cash distribution to ADS holders 
 
A fee equivalent to the fee that would be payable if securities distributed 
to you had been shares and the shares had been deposited for issuance of
ADSs 
Distribution of securities distributed to holders of deposited securities 
(including rights) that are distributed by the depositary to ADS holders
 
US$0.05 (or less) per ADS per calendar year 
Depositary services 
 
Registration or transfer fees 
Transfer and registration of shares on our share register to or from the 
name of the depositary or its agent when you deposit or withdraw shares
 
Expenses of the depositary 
Cable and facsimile transmissions (when expressly provided in the 
deposit agreement) 
  
Converting foreign currency to U.S. Dollars 
 
Taxes and other governmental charges the depositary or the custodian has
to pay on any ADSs or shares underlying ADSs, such as stock transfer 
taxes, stamp duty or withholding taxes 
As necessary 
 
Any charges incurred by the depositary or its agents for servicing the 
deposited securities 
As necessary 
 
The depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares 
or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects 
fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion 
of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by 

 
183 
 
deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts of 
participants acting for them. The depositary may collect any of its fees by deduction from any cash distribution 
payable (or by selling a portion of securities or other property distributable) to ADS holders that are obligated to pay 
those fees. The depositary may generally refuse to provide fee-attracting services until its fees for those services are 
paid.  
From time to time, the depositary may make payments to us to reimburse us for costs and expenses generally 
arising out of establishment and maintenance of the ADS program, waive fees and expenses for services provided to 
us by the depositary or share revenue from the fees collected from ADS holders. For the year ended December 31, 
2024, the depositary reimbursed us a gross amount of US$50,000 in connection with the ADS program. 
In performing its duties under the deposit agreement, the depositary may use brokers, dealers, foreign 
currency dealers or other service providers that are owned by or affiliated with the depositary and that may earn or 
share fees, spreads or commissions.  
The depositary may convert currency itself or through any of its affiliates and, in those cases, acts as 
principal for its own account and not as agent, advisor, broker or fiduciary on behalf of any other person and earns 
revenue, including, without limitation, transaction spreads, that it will retain for its own account. The revenue is based 
on, among other things, the difference between the exchange rate assigned to the currency conversion made under the 
deposit agreement and the rate that the depositary or its affiliate receives when buying or selling foreign currency for 
its own account. The depositary makes no representation that the exchange rate used or obtained in any currency 
conversion under the deposit agreement will be the most favorable rate that could be obtained at the time or that the 
method by which that rate will be determined will be the most favorable to ADS holders, subject to the depositary’s 
obligations under the deposit agreement. The methodology used to determine exchange rates used in currency 
conversions is available upon request.  
You will be responsible for any taxes or other governmental charges payable on your ADSs or on the 
deposited securities represented by any of your ADSs. We, the depositary bank and the custodian may withhold or 
deduct from any distribution the taxes and governmental charges payable by holders and the depositary may sell any 
and all property on deposit to pay the taxes and governmental charges payable by holders. You will be liable for any 
deficiency if the sale proceeds do not cover the taxes that are due.  
The depositary may refuse to register any transfer of your ADSs or allow you to withdraw the deposited 
securities represented by your ADSs until those taxes or other charges are paid. It may apply payments owed to you 
or sell deposited securities represented by your ADSs to pay any taxes owed and you will remain liable for any 
deficiency. If the depositary sells deposited securities, it will, if appropriate, reduce the number of ADSs to reflect the 
sale and pay to ADS holders any proceeds, or send to ADS holders any property, remaining after it has paid the taxes. 
You are required to indemnify us, the depositary and the custodian for any claims with respect to taxes based on any 
tax benefit obtained for you.

CONTROLS AND PROCEDURES 
Disclosure Controls and Procedures 
We have evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the 
effectiveness of the design and operation of the Company’s disclosure controls and procedures pursuant to 13a-15(e) 
and 15d-15(e) of the Exchange Act, as of December 31, 2024. 

 
184 
 
There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, 
including the possibility of human error and the circumvention or overriding of the controls and procedures. 
Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving 
their control objectives. Based upon our evaluation, we, with the participation of our Chief Executive Officer and 
Chief Financial Officer, concluded that as of December 31, 2024, our disclosure controls and procedures were 
effective to provide reasonable assurance that information required to be disclosed by us in the reports that we file or 
submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in 
the applicable rules and forms, and that it is accumulated and communicated to our management, including our Chief 
Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. 
Management’s Annual Report On Internal Control Over Financial Reporting 
Our management is responsible for establishing and maintaining adequate internal control over financial 
reporting as defined in Rules 13a-15(f) and 15(d)-15(f) under the Securities Exchange Act of 1934. Our internal 
control over financial reporting is a process designed under the supervision of our Chief Executive Officer and Chief 
Financial Officer, and monitored by our board of directors, management and other personnel, to provide reasonable 
assurance regarding the reliability of financial reporting and the preparation of our financial statements for external 
reporting purposes in accordance with IFRS as issued by the IASB, and it includes those policies and procedures that: 
(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions, 
dispositions of our assets, and treasury policies; (ii) provide reasonable assurance that transactions are recorded as 
necessary to permit preparation of financial statements in accordance with IFRS, and that receipts and expenditures 
are being made only in accordance with authorization of our management and directors; and (iii) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that 
could have a material effect on our financial statements. 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect 
misstatements. Therefore, effective control over financial reporting cannot, and does not, provide absolute assurance 
of achieving our control objectives. Also, projection of any evaluation of the effectiveness of the internal controls to 
future periods is subject to the risk that controls may become inadequate because of changes in conditions or that the 
degree of compliance with the policies or procedures may deteriorate.  
As of the year ended December 31, 2024, our management conducted an assessment of the effectiveness of 
our internal control over financial reporting in accordance with the criteria established in the publication “Internal 
Control – Integrated Framework (2013),” issued by the Committee of the Sponsoring Organizations of the Treadway 
Commission, as well as the rules set by the SEC in its Final Rule “Management’s Report on Internal Control Over 
Financial Reporting and Certification of Disclosure in Exchange Act Periodic Reports.”  
Based on the assessment performed, management concluded that our internal control over financial reporting 
was effective as of the end of the period covered by this annual report. 
Attestation report of the registered public accounting firm 
Reference is made to the report of EY Argentina (as defined below) on page F-3 of this annual report. 
Changes in internal control over financial reporting 
There was no change in our internal control over financial reporting that occurred during the period covered 
by this annual report that has materially affected, or is reasonably likely to materially affect, our internal control over 
financial reporting. 
During 2024, the Company completed the fifth year of implementation of specific standards for the SOX and 
performed a management assessment over internal control.

our web site at: www.vistaenergy.com. We did not modify or amend our Code of Ethics and Conduct during the year 
ended December 31, 2024. In addition, we did not grant any waivers to our Code of Ethics and Conduct during the 
year ended December 31, 2024. 
Our Code of Ethics and Conduct defines the way in which we conduct our businesses, and it is designed to 
help us comply with our obligations, to respect one another at the workplace and to act with integrity in the market. 
Our Code of Ethics and Conduct expressly sets forth, among other matters, that no one shall offer, in the name of 
Vista, directly or indirectly through third parties, anything of value to a public officer, or to his/her representatives, 
and particularly for the purposes of obtaining or maintaining a business, influencing business decisions or receiving 
an unfair advantage. 
Additionally, Vista’s mission to conduct business in an ethical manner also entails the commitment of 
maintaining accuracy in our accounting books, financial statements and accounting records. Our accounting records, 
including our financial statements, management reports, contracts and agreements, must always be accurate and 
reflect the economic facts and transactions with integrity and accuracy, pursuant to the professional accounting 
standards and the laws governing Vista. All of Vista’s transactions, regardless of their amount, must be properly 
authorized, executed and recorded. Upon a determination that our Code of Ethics and Conduct has been violated, the 
Company shall take any appropriate disciplinary action.

ITEM 16G. CORPORATE GOVERNANCE  
Corporate Governance Practices  
Companies listed on the NYSE must comply with the corporate governance standards provided under 
Section 303A of the NYSE Listed Company Manual. As a foreign private issuer, we are permitted to follow home 

 
187 
 
country practices in lieu of Section 303A, except that we are required to comply with Sections 303A.06, 303A.11 and 
303A.12(b) and (c) of the NYSE Listed Company Manual. Under Section 303A.06, we must have an audit committee 
that meets the independence requirements of Rule 10A-3 under the Exchange Act. Under Section 303A.11, we must 
disclose any significant ways in which their corporate governance practices differ from those followed by domestic 
companies under NYSE listing standards. Finally, under Section 303A.12(b) and (c), we must promptly notify the 
NYSE in writing after becoming aware of any non-compliance with any applicable provisions of this Section 303A 
and must annually make a written affirmation to the NYSE.  
The table below briefly describes the significant differences between our Mexican corporate governance 
rules and the NYSE corporate governance rules.  
Section 
NYSE Corporate Governance Rules 
Mexican Corporate Governance Rules 
303A.01 
A listed company must have a majority of independent 
directors. “Controlled companies” are not required to comply 
with this requirement. 
A listed company must have at least 25% of independent 
directors. All listed companies must comply with this

Risk Management and Strategy 
Our risk management framework includes regular assessments and updates to our cybersecurity policies, 
aligning them closely with industry best practices and emerging threats. We emphasize a proactive approach, 
integrating cybersecurity considerations into our strategic planning and operational processes. This ensures that 

 
189 
 
potential risks are identified and mitigated before they can impact our operations. Additionally, our strategy is 
structured according to the categories of the NIST Cybersecurity Framework, providing a solid and standardized 
foundation for our cybersecurity practices.  
Govern 
• 
Cybersecurity processes are overseen by our Cybersecurity team, which reports to the Innovation and 
Technology Manager, who in turn reports to the CTO. The leader of our Cybersecurity team has over 12 
years of experience in the field across various industries.

The Cybersecurity team provides quarterly reports to the Cybersecurity Internal Committee, which oversees 
and sponsors the cybersecurity strategy. This committee has received fundamental cybersecurity training 
from a top-tier third-party consultant. Our CTO, who chairs the committee, provides quarterly updates to the 
Corporate Practices Committee of the Board of Directors. 
 
• 
As part of our management process, the committee receives quarterly reports on the following key 
performance indicators: 
 
o NIST Maturity Score; 
 
o Number of critical incidents that occurred during the period; 
 
o Distribution of cybersecurity monitoring alerts within the period; 
 
o Number of critical risk scenarios identified with a level 1 post-mitigation rating (highest impact and 
probability of occurrence); 
 
o Percentage of employees who completed mandatory cybersecurity training; and  
 
o Average results of controlled phishing exercises. 
 
• 
The Company’s cybersecurity and information security strategy is based on comprehensive risk assessment, 
mitigation, and resilience readiness. This is achieved through a threat intelligence-driven approach, 
application controls, and reinforced ransomware defense mechanisms. The framework follows several 
international standards, including NIST Special Publication 800-53 for general IT controls, ISA/IEC 
standards for industrial automation, the NIST Cybersecurity Framework for evaluating overall readiness, and 
SOX for assessing internal controls. 
 
• 
We have implemented a Cybersecurity Policy and Standards, which serve as a comprehensive framework for 
our cybersecurity rules, technical standards, and procedures. This document is aligned with our corporate 
operating management system and establishes guidelines for developing, implementing, and enhancing 
procedures to protect information from unauthorized access and misuse, ensure the availability of critical 
systems, and maintain data protection and integrity. This policy is the cornerstone of our information 
security management system and an integral part of our cybersecurity governance framework. 
 
Identify 
 
• 
We maintain a comprehensive process for assessing, identifying, and managing material risks from 
cybersecurity threats, including risks related to business operations disruption, financial reporting systems, 
intellectual property theft, fraud, extortion, harm to employees or customers, violation of privacy laws, 
litigation and legal risks, and reputational risks. 
 
• 
Risk assessments are conducted on an ongoing basis. The likelihood and impact of each risk are determined 
using a qualitative risk assessment methodology. Risks are identified from various sources, including 
vulnerability scans and penetration tests. We monitor our infrastructure and applications to detect evolving 
cyber threats and possible intrusions. The assessment results are reported quarterly to Company management 
through our cybersecurity risk matrix in accordance with the established cybersecurity governance model.

and attack simulation activities. 
 
• 
The Cybersecurity team conducts annual information security awareness training for all employees, performs 
internal phishing tests, provides targeted training for employees who click on phishing attempts, mandates 
security training for new hires, and publishes cybersecurity newsletters to address emerging or urgent 
security threats. 
 
Detect and Respond 
 
• 
We have a Cybersecurity Incident Response Plan that outlines the procedures for handling cybersecurity 
incidents based on their severity and ensures cross-functional coordination. Additionally, we have 
established a Cybersecurity Detection and Response team to provide real-time enterprise visibility into cyber 
incidents. 
 
• 
Our business strategy, operational results, and financial condition have not been significantly impacted by 
cybersecurity threats or past incidents. However, we cannot guarantee that they will remain unaffected by 
such risks or future significant incidents. Over the past four fiscal years, we have not experienced any 
significant information security breaches, and expenses incurred from minor breaches have been 
insignificant. This includes penalties and settlements, of which there have been none. 
 
Recover 
 
• 
The Company conducts cybersecurity tabletop and crisis management exercises facilitated by an independent 
third party to simulate breach and other information security scenarios. The facilitator poses questions to 
participants and provides insights into typical responses from other companies in similar situations. These 
exercises help assess and enhance response strategies, improving practices, procedures, and technologies.

Report of Independent Registered Public Accounting Firm 
 
To the Shareholders and Board of Directors of  
Vista Energy, S.A.B. de C.V.: 
  
Opinion on the Financial Statements 
  
We have audited the accompanying consolidated statements of financial position of Vista Energy, S.A.B. de C.V. (the Company) 
as of December 31, 2024 and 2023, the related consolidated statements of profit or loss and other comprehensive income, changes 
in equity and cash flows for the two years in the period ended December 31, 2024, and the related notes (collectively referred to 
as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material 
respects, the financial position of the Company at December 31, 2024 and 2023, and the results of its operations and its cash 
flows for each of the two years in the period ended December 31, 2024, in conformity with IFRS Accounting Standards as issued 
by the International Accounting Standards Board (IASB).  
 
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in 
Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission 
(2013 framework) and our report dated April 9, 2025 expressed an unqualified opinion thereon.  
 
Basis for Opinion 
  
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on 
the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB. 
 
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to 
error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, 
whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a 
test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the 
accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the 
financial statements. We believe that our audits provide a reasonable basis for our opinion. 
  
Critical Audit Matter 
  
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that 
was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that 
are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The 
communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken 
as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit 
matter or on the account or disclosure to which it relates. 
 
 
Impact of estimated proved oil and gas reserves on the depreciation of Oil and Gas 
Properties and Production Wells and Facilities 
 
 
Description of the 
matter 
As described in Note 13 to the consolidated financial statements, at December 31, 2024, Oil and 
Gas Properties and Production Wells and Facilities was $2,485,056 thousand and had an associated 
depreciation expense for 2024 of $415,963 thousand. As described in Note 3.2.5, depreciation of 
those assets is calculated using the unit-of-production method based on proved oil and gas reserves, 
developed and not developed as applicable, based on the estimates certified by an independent 
reserves engineering consultant. 
 
Proved oil and gas reserves are those quantities of natural gas, crude oil, and natural gas liquid 
which by analysis of geoscience and engineering data, can be estimated with reasonable certainty 
to be economically producible from a given date forward, from known reservoirs, and under 
existing economic conditions, operating methods, and government regulations. Judgment is 
required by the independent reserves engineering consultant in evaluating geological and 
engineering data when estimating oil and gas reserves. Estimating reserves also requires the 
selection and evaluation of inputs, including historical production, oil and gas price assumptions, 
and future operating and capital cost assumptions, among others.   
 

F-3 
Auditing the Company’s depreciation calculation is complex because of the use of the work of the 
independent reserves engineering consultant and the evaluation of management’s determination of 
the inputs described above used by the independent reserves engineering consultant in estimating 
proved oil and gas reserves. 
 
How We Addressed 
the Matter in our 
Audit 
We obtained an understanding, evaluated the design and tested the operating effectiveness of the 
Company’s controls over its process to calculate the depreciation, including management’s controls 
over the completeness and accuracy of the financial data provided to the independent reserves 
engineering consultant for use in estimating proved oil and gas reserves.   
 
Our audit procedures included, among others, evaluating the professional qualifications and 
objectivity of the independent reserves engineering consultant and management’s qualified person 
responsible for overseeing the preparation of the proved oil and gas reserve estimates. In addition, 
we evaluated the completeness and accuracy of the financial inputs described above used by the 
independent reserves engineering consultant in estimating proved oil and gas reserves by agreeing 
them to source documentation, and we identified and evaluated corroborative and contrary 
evidence. We also tested the mathematical accuracy of the depreciation calculation, including 
comparing the proved oil and gas reserves amounts used in the calculation to the certified reserve 
report prepared by the independent reserves engineering consultant.

Report of Independent Registered Public Accounting Firm 
 
To the Shareholders and the Board of Directors of  
Vista Energy, S.A.B. de C.V. 
  
Opinion on Internal Control Over Financial Reporting 
  
We have audited Vista Energy, S.A.B. de C.V.’s (the Company) internal control over financial reporting as of December 
31, 2024, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (2013 framework), (the COSO criteria). In our opinion, Vista Energy, S.A.B. de 
C.V. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on 
the COSO criteria.  
 
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the consolidated statements of financial position of Vista Energy, S.A.B. de C.V. as of December 31, 2024 
and 2023, the related consolidated statements of profit or loss and other comprehensive income, changes in equity and cash flow 
for each of the two years in the period ended December 31, 2024, and the related notes, and our report dated April 9, 2025 
expressed an unqualified opinion thereon.  
 
Basis for Opinion 
  
The Company’s management is responsible for maintaining effective internal control over financial reporting and for 
its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s 
Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s 
internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB.  
   
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained 
in all material respects.  
   
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a 
material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed 
risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides 
a reasonable basis for our opinion.  
 
Definition and Limitations of Internal Control Over Financial Reporting 
  
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding 
the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures 
that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 
expenditures of the company are being made only in accordance with authorizations of management and directors of the 
company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements.  
    
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Change in Accounting Principle 
As discussed in Note 2.6 to the consolidated financial statements, the Company has elected to change its method of accounting 
for the presentation of export duties in the consolidated statements of profit or loss and other comprehensive income for the year 
ended December 31, 2022. 
 
Basis for Opinion  
 
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on 
the Company’s consolidated financial statements based on our audit. We are a public accounting firm registered with the Public 
Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company 
in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange 
Commission and the PCAOB. 
 
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to 
error or fraud. The Company is not required to have, nor were we engaged to perform an audit of its internal control over financial 
reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting, but not for 
the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. 
Accordingly, we express no such opinion. 
 
Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due 
to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, 
evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting 
principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial 
statements. We believe that our audit provides a reasonable basis for our opinion.

Note 2. Basis of preparation and material accounting policies  
 
2.1 Basis of preparation and presentation  
 
The accompanying consolidated financial statements as of December 31, 2024, and 2023, and for the years ended December 31, 2024, 
2023 and 2022, were prepared in accordance with the IFRS Accounting Standards issued by the International Accounting Standards 
Board (“IASB”).  
 
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. 
 
These consolidated financial statements were approved by management for inclusion in the Company’s annual report on Form 20-F 
on April 9, 2025, and the subsequent events through that date are considered (Note 33).  
 
2.2 New accounting standards, amendments and interpretations issued by the IASB  
 
2.2.1 New effective accounting standards, amendments and interpretations issued by the IASB adopted by the Company 
 
Amendments to International Accounting Standards 1 (“IAS”): Presentation of Financial Statements. Classification of 
Liabilities as Current or Non-current 
 
In October 2022, the IASB published changes to certain paragraphs of IAS 1 to specify the requirements for classifying liabilities as 
current or non-current. The amendments clarify:  
 
(i) What is meant by a right to defer settlement; 
(ii) That a right to defer must exist at the end of the reporting period; 
(iii) That classification is unaffected by the likelihood that an entity will exercise its deferral right and; 
(iv) That only if an embedded derivative in a convertible liability is itself an equity instrument would the terms of a liability not impact 
its classification. 
 
The amendments are effective for annual periods beginning on or after January 1, 2024. 
 
The amendments had no impact on the Company’s consolidated financial statements as the current accounting policies are aligned to 
the amendments.  
 
Amendments to IAS 7: Statements of Cash Flows, and International Financial Reporting Standards (“IFRS”) 7: Financial 
Instruments: Disclosures – Disclosure of Supplier Finance Arrangements 
 
On May 25, 2023, the IASB published amendments to IAS 7 and IFRS 7 whereby it introduces new disclosure requirements in IFRS 
Standards to enhance the transparency and, thus, the usefulness of the information provided by entities about supplier finance 
arrangement. The new requirements aim to facilitate a better understanding of supplier finance arrangements on an entity’s liabilities, 
cash flows and exposure to liquidity risk. 
 
The amendments are effective for annual periods beginning on or after January 1, 2024. 
 
The amendments had no impact on the Company’s consolidated financial statements as the current accounting policies are aligned to 
the amendments.

F-17 
Amendments to IFRS 16: Leases. Recognition of lease liabilities in a sale and leaseback 
 
In September 2022, the IASB published amendments to IFRS 16 related to the recognition of lease liabilities in a sale and leaseback. 
The amendment specifies the requirements that a seller-lessee should use to measure the lease liability arising in a sale to ensure the 
seller-lessee does not recognize any amount of the gain or loss that relates to the right of use it retains. 
 
The amendments are effective for annual periods beginning on or after January 1, 2024. 
 
These amendments had not impact on the Company’s consolidated financial statements, since it has no sale and leaseback transactions. 
 
2.2.2 New accounting standards, amendments and interpretations issued by the IASB not yet effective    
 
IFRS 18: Presentation and Disclosure in Financial Statements 
 
On April 9, 2024, the IASB issued IFRS 18 - Presentation and Disclosure in Financial Statements, amending IAS 1 - Presentation of 
Financial Statements to introduce new requirements for the presentation and disclosure of information in financial statements and the 
related explanatory notes, as well as the requirement to disclose Management-defined performance measures. 
 
Among others, IFRS 18 requires companies to classify revenue and expenses of “Statement of profit and other comprehensive income” 
in the following categories: (i) operating: (ii) investing; (iii) financing; (iv) income tax, and (v) discontinued transactions. It also sets 
forth the requirement to file subtotals and totals for: (i) operating profit or loss; (ii) profit or loss before financing and income tax, and 
(iii) profit or loss for the period. 
 
In addition, it requires that companies disclose Management-defined Performance Measures (“MPM”) in a note to the financial 
statements, explaining the calculation method, and reconciliation with the financial information filed, among others. 
 
Finally, limited-scope amendments were made to the following standards: (i) IAS 7 - Statement of Cash Flows; (ii) IAS 8- Accounting 
Policies, Changes in Accounting Estimates and Errors, and (iii) IAS 34- Interim Financial Reporting. 
 
The amendments will become effective for annual periods beginning on or after January 1, 2027. Early adoption is allowed.  
 
The Company is assessing the impact of IFRS 18 on its consolidated financial statements.  
 
Amendments to IAS 21: The Effects of Changes in Foreign Exchange Rates - Lack of Exchangeability 
 
In August 2023, the IASB issued amendments to IAS 21 - The Effects of Changes in Foreign Exchange Rates to clarify when entities 
are required to assess if a currency is exchangeable into another currency, and how to determine the exchange rate when a currency is 
not exchangeable.  
 
The amendments also require that information be disclosed so that the users of the financial statements may assess how the lack of 
exchangeability affects profit and financial position, and cash flows.  
 
The amendments will become effective for annual periods beginning on or after January 1, 2025. Early adoption is allowed, but 
comparative information cannot be restated.  
 
The Company is assessing the impact of these amendments on its consolidated financial statements.

2.3.1 Subsidiaries  
 
Subsidiaries are all entities over which the Company has control, which occurs if and only if the Company has all the following:  
(i) 
Power over the entity;  
(ii) Exposure or rights to variable returns from its involvement with the entity; and  
(iii) The ability use its power over the entity to affect the amount of the investor’s returns.   
 
The Company reassesses whether it controls a subsidiary if facts or circumstances indicate that there are changes to 1 or more of the 
3 elements of control mentioned above. 
 
When the Company does not have a majority of the voting rights of an investee, it has power over the latter when the voting rights are 
sufficient to give it the practical ability to direct the relevant activities of the investee unilaterally.  
 
The Company assesses all facts and circumstances to determine whether voting rights are sufficient to give it power over an entity, 
including: 
 
(i) 
The size of the Company’s holding of voting rights relative to the size and dispersion of holdings of the other vote holders; 
(ii) potential voting rights held by the Company, other vote holders or other parties; 
(iii) rights arising from other contractual arrangements; and 
(iv) any additional facts and circumstances that indicate the Company has, or does not have, the current ability to direct the relevant 
activities at the time that decisions need to be made, including voting patterns at previous shareholders’ meeting. 
 
Relevant activities are those that most significantly affect the subsidiary’s performance, such as the ability to approve an operating 
and capital budget and the power to appoint Management personnel, among others. 
 
Subsidiaries are consolidated from the date the Company obtains control over them and ceases when such control ends. Specifically, 
profit and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated statements of profit or loss 
and other comprehensive income as from the date in which the Company obtains control until it assigns or loses such control. 
 
Intercompany transactions, balances and income or losses are deleted. The subsidiaries’ financial statements are adjusted when needed 
to align their accounting policies to the Company’s accounting policies.

2.3.2 Changes in interests  
 
Changes in the Company’s working interests in its subsidiaries that do not result in a change in control of the subsidiary are accounted 
for as equity transactions. The carrying amount of the Company’s interests is adjusted to reflect the changes in interests in the 
subsidiaries.  
 
When the Company ceases to consolidate or book a subsidiary for loss of control, joint control or significant influence, any retained 
working interest in the entity is remeasured at fair value with the change in the carrying amount recognized in the consolidated 
statements of profit or loss and other comprehensive income. This fair value becomes the initial carrying amount for the purposes of 
subsequently booking retained interest as the associate, joint venture or financial asset.  
 
In addition, any amount previously recognized in other comprehensive income in relation to such entity is booked as if the Company 
had directly disposed of the related assets or liabilities. This may mean that the amounts previously recognized in other comprehensive 
income are reclassified to profit or loss. 
 
If the working interest in a joint venture or associate is reduced, but the entity retains the joint control or significant influence, only a 
proportion of the previously recognized amounts in other comprehensive income is reclassified to profit or loss. 
 
2.3.3 Joint arrangements  
 
According to IFRS 11 Joint Arrangements, investments are classified as joint operations or joint venture, depending on contractual 
rights and obligations. The Company has joint operations but has no joint venture. 
 
Joint operations 
 
A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the assets, and 
obligations for the liabilities, relating to the arrangement. Joint control exists only when decisions about the relevant business activities 
require the unanimous consent of the parties that collectively control the arrangement. 
 
When the Company carries out activities under joint operations, recognize in proportion to its interest: 
 
(i) 
Its assets and liabilities held jointly; 
(ii) Its revenue from the sale of its share of the output of the joint operation; and 
(iii) Its expenses, including its share of any expenses incurred jointly. 
 
The Company books its assets, liabilities, revenues and expenses related to its interest in a joint operation according to the IFRS 
applicable. They were included in the consolidated financial statements in the related accounts. Interest in joint operations were based 
on the latest financial statements or financial information available as of every year-end considering significant subsequent events and 
transactions, and management information available. The financial statements or the financial information of the joint operations are 
adjusted, if needed, so that the accounting policies are consistent with the Company’s accounting policies.

See Note 1.1 and 29 for further information on the Company’s joint operations. 
 
2.3.4 Business combination 
 
The acquisition method is used to book business combinations, regardless of whether equity instruments or other assets are acquired. 
The consideration transferred for these acquisitions comprises:  
 
(i) 
The fair value of transferred assets; 
(ii) The liabilities incurred to former owners of the acquired business; 
(iii) The equity interests issued by the Company; 
(iv) The fair value of any asset or liability from a contingent consideration arrangement; and  
(v) The fair value of any previously held equity interest in the subsidiary. 
 
Identifiable assets acquired and contingent liabilities assumed in a business combination are initially measured at fair values at the 
date of purchase.  
 
The costs related to the acquisition are booked as incurred expenses. Goodwill is an excess of: 
 
(i) 
The consideration transferred; and 
(ii) The fair value of net identifiable assets acquired. 
 
If the fair value of the acquiree’s net identifiable assets exceeds these amounts, before recognizing profit, the Company reassesses 
whether it has correctly identified all assets acquired and liabilities assumed, reviewing the procedures employed to measure the 
amounts to be recognized at the acquisition date. If the assessment still results in excess of the fair value of net assets acquired in 
relation to the total consideration transferred, gain from a bargain purchase is recognized directly in the consolidated statements of 
profit or loss and other comprehensive income. 
 
When the settlement of any cash consideration is deferred, the future amounts payable is discounted at their present value at the 
exchange date. The discount rate used is the entity’s incremental borrowing rate, being the rate at which a similar borrowing could be 
obtained under comparable terms and conditions. 
 
Contingent consideration will be recognized at its fair value at the acquisition date. Contingent consideration is classified as equity or 
as a financial liability. The amounts classified as a financial liability are remeasured at fair value with changes in fair value through 
the consolidated statements of profit or loss and other comprehensive income. Contingent consideration classified as equity is not 
remeasured and its subsequent settlement is accounted for within equity. 
 
When the Company acquires a business, it assesses the financial assets acquired and liabilities incurred in relation to its adequate 
classification and designation according to contractual terms, economic circumstances and relevant conditions as of the acquisition 
date.  
 
Oil reserves and resources acquired that may be measured reliably are recognized separately at fair value upon the acquisition. Other 
potential reserves, resources and rights, which fair values cannot be measured reliability, are not recognized separately but are 
considered part of goodwill. 
 
If the business combination is performed in stages, the previously held equity interest in the acquiree is measured at acquisition-date 
fair value. Profit or loss from such remeasurement is recognized in the consolidated statements of profit or loss and other 
comprehensive income. 
 
The Company has a maximum period of 12 months from the date of acquisition to finalize the acquisition accounting. When it is 
incomplete as of the end of the year in which the business combination takes place, the Company reports provisional amounts.

2.4 Summary of material accounting policies    
 
2.4.1 Segment information  
 
The operating segments are reported in a consistent manner with the internal reports provided by the Executive Management 
Committee (the “Committee” that is considerate the “Chief Operating Decision Maker” or “CODM”). 
 
The CODM is the highest decision-making authority, in charge of allocating resources and establishing the performance of the entity’s 
operating segments and was identified as the body executing the Company’s strategic decisions.  
 
2.4.2 Property, plant and equipment and intangible assets 
 
Property, plant and equipment 
 
Property, plant and equipment is measured using the cost model, the asset is valued at cost less depreciation and any subsequent 
accumulated impairment loss.  
 
Subsequent costs are included in the carrying amount of the asset or are recognized as a separate asset, as the case may be, only when 
it is probable that future economic benefits may flow to the Company and the cost of the asset may be measured reliably, otherwise 
such costs are charged to profit or loss during the reporting period in which they are incurred.  
 
Works in progress are booked at cost less any impairment loss, of applicable. 
 
Profit and loss from the sale of property, plant and equipment is calculated by comparing the consideration received with the carrying 
amount of the date in which the transaction was carried out. 
 
2.4.2.1 Depreciation methods and useful lives  
 
Estimated useful lives, residual values and the depreciation method are reviewed at every period-end, and changes are recognized 
prospectively. An asset is impaired when its carrying amount exceeds its recoverable amount. 
 
The Company considers climate-related matters, including physical and energy transition risks, and determines if applicable 
regulations may affect the useful life or residual value of property, plant and equipment; for example, should machines and facilities 
using fuel fossils be prohibited or restricted, or if additional energy efficiency requirements are introduced (Note 2.4.19). 
 
The Company amortizes drilling costs applicable to productive and in development, and production facilities, according to the unit of 
production method ("UDP" by Spanish acronym), applying the proportion of Crude oil and Natural gas produced to prove and develop 
Crude oil and Natural gas reserves, as the case may be. 
 
The mineral properties is amortized applying the proportion of produced Crude oil and Natural gas to total estimated Crude oil and 
Natural gas proved reserves. 
 
The costs of acquiring properties with unproved reserves are valued at cost, and their recoverability is assessed regularly based on 
geological and engineering estimates of the reserves and resources expected to be proved during the life of each concession and are 
not depreciated.  
 
Capitalized costs related to the acquisition of properties and the extension of concessions with proved reserves were depreciated per 
field based on a UDP by applying the proportion of produced Crude oil and Natural gas to estimated total proved oil and gas reserves. 
(Note 2.4.2.3).

The Company’s remainder items of property, plant and equipment are depreciated using the straight-line method based on their 
estimated useful lives, as detailed below: 
 
Buildings 
50 years 
Machinery and installations 
10 years 
Equipment and furniture  
10 years 
Vehicles 
5 years 
Computer equipment 
3 years 
 
Land does not depreciate. 
 
2.4.2.2 Assets for oil and gas exploration  
 
The Company adopts the successful effort method to account for its oil and gas exploration and production activities. 
 
This method implies the capitalization of: (i) the cost of acquiring properties in oil and gas exploration and production areas; (ii) the 
cost of drilling and equipping exploration wells arising from the discovery of commercially recoverable reserves; (iii) the cost of 
drilling and equipping development wells; located in proved reserves areas; and (iv) estimated well plugging and abandonment 
obligations.  
 
Exploration and evaluation involve the search for hydrocarbon resources, the assessment of its technical viability and the assessment 
of the commercial feasibility of an identified resource. 
 
According to the successful effort method, exploration costs such as geological and geophysical ("G&G") costs, excluding the costs 
of exploration wells and 3D seismic testing in operating concessions, are expensed in the period in which they are incurred. 
 
These capitalized costs are subject to technical, commercial and administrative review, and a review of impairment indicators at least 
once a year. When there is sufficient management information indicating impairment, the Company conducts an impairment test 
according to the policies described in Note 3.2.2.  
 
Estimated well plugging and abandonment obligations in hydrocarbon areas, discounted at a risk-adjusted rate, are capitalized in the 
cost of assets and are amortized using the UDP method. A liability for the estimated value of discounted amounts payable is also 
recognized. Changes in the measurement of these obligations as a consequence of changes in the estimated term, the cost or discount 
rate are added to or deducted from the cost of the related asset.  
 
2.4.2.3 Rights and Concessions  
 
Rights and concessions are booked as part of property, plant and equipment and are depleted on the UDP over the total proved reserves 
of the relevant area. The calculation of the UDP rate for the depreciation of development costs considers expenses incurred to date 
and authorized future development expenses. 
 
2.4.2.4 Goodwill and Other intangible assets 
 
(i) Goodwill 
 
 
Goodwill arises during an initial business combination and represents the excess of the consideration transferred over the fair value 
of net assets acquired. After initial recognition, goodwill is measured at cost less cumulative impairment losses.  
 
To conduct impairment tests, goodwill is allocated as from acquisition date to each cash-generating unit ("CGU"), which represents 
the lowest level within the Company at which the goodwill is monitored for internal management purposes. Goodwill is tested once 
a year. 
 
When goodwill is allocated to a CGU and part of the transaction within such unit is eliminated, goodwill related to such eliminated 
transaction is included in the carrying amount of the transaction to determine gain or loss on sale.

F-23 
The Company constantly assesses weather-related risks, including physical and energy transitions risks in measuring the recoverable 
value of the business credit (Note 2.4.19). 
 
(ii) Other intangible assets 
 
Other intangible assets acquired separately are measured using the cost model; after initial recognition, the asset is valued at cost less 
amortization and any subsequent accumulated impairment loss. 
 
Intangible assets are amortized using the straight-line method; software licenses are amortized over their estimated 3 year useful life. 
The amortization of these assets is recognized in the consolidated statements of profit or loss and other comprehensive income.  
 
The estimated useful life, residual value and amortization method are reviewed at every period-end, and changes are recognized 
prospectively.  
 
2.4.3 Leases 
 
The Company has lease contracts for various items of buildings, facilities and machinery, which are recognized under IFRS 16.  
 
The Company recognizes right-of-use assets at the commencement date of the underlying asset is available for use. Right-of-use assets 
are measured at cost, net of the accumulated depreciation and impairment losses, and are adjusted by the remeasurement of lease 
liabilities. The cost of assets includes the amount for recognized liabilities, direct costs initially incurred, and payments made until the 
commencement date. Unless the Company is reasonably certain that it will obtain the ownership of the leased asset at the end of the 
contract, these assets are depreciated under the straight-line method during the lease term. 
 
Right-of-use assets are subject to impairment, as mentioned on the accounting policy, to impairment of long -lived assets other than 
goodwill (Note 3.2.2). 
 
The Company recognizes lease liabilities measured at the present value of the payments to be made during the lease term. These 
payments include fixed payments, variable payments dependent on an index or rate, and the purchase option and the penalty payments 
from lease termination. The Company determines the lease term as the noncancellable lease term, together with any period covered 
by an option to extend the agreement if it is reasonably certain that it will exercise that option. To calculate the present value of lease 
payments, the Company uses the incremental borrowing rate at the lease contract.  
 
After the commencement date, liabilities will be increased to reflect the accretion of interest and will be reduced by the payments 
made. In addition, the carrying amount of lease liabilities are remeasured if there is an amendment, a change in the lease term, a 
change in the fixed or in-substance fixed payments or a change in the assessment to buy the underlying asset. 
 
The Company applies the exemption to recognize short-term leases (i.e., those leases for a term under 12 months as from the 
commencement date with no call option). Also, the low-value asset exemption also applies to low-value items. The lease payments of 
low-value assets are recognized as expenses under the straight-line method during the lease term. 
 
2.4.4 Impairment of property, plant and equipment, right-of-use assets and identifiable intangible assets (“long -lived assets”) 
other than goodwill 
 
Other long-lived assets with a definite useful life undergo impairment tests whenever events or changes in circumstances have 
indicated that their carrying value may not be recoverable. When the carrying amount of the asset exceeds its recoverable amount, an 
impairment loss is recognized for the value of the asset. An asset’s recoverable amount is the higher of (i) the fair value of an asset 
less costs of disposal and (ii) its value in use.  
 
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 CGUs. Amortized long-lived assets are reviewed for potential reversal of impairment at the 
end of each reporting period. 
 
The Company constantly assesses weather-related risks, including physical and energy transitions risks, could have a significant 
impact and its eventual inclusion in the cash flows to determine the recoverable value (Note 2.4.19).

See Note 3.2.2 for further information on impairment of long-lived assets other than Goodwill. 
 
2.4.5 Foreign currency translation  
 
2.4.5.1 Functional and presentation currency 
 
The functional currency of the Company and its subsidiaries is the USD, the currency of the primary economic context in entity 
operates. To determine the functional currency, the Company makes judgments, and it must be reconsiders in the event of a change 
in conditions that may determine the primary economic context. 
 
The presentation currency of the Company is USD. 
 
2.4.5.2 Transactions and balances  
 
Transactions in a currency other than the functional currency (“foreign currency”) are accounted for at the exchange rate as of each 
transaction date. Foreign exchange gains and losses from the settlement of transactions and the translation at the closing exchange 
rate of monetary assets and liabilities denominated in foreign currency are recognized in the consolidated statements of profit or loss 
and other comprehensive income in “Other financial income (expense)” under “Net changes in foreign exchange rate”. 
 
Monetary balances in foreign currency are converted at each country’s official exchange rate as of every year-end.  
 
2.4.6 Financial instruments  
 
2.4.6.1 Financial assets 
  
2.4.6.1.1 Classification 
 
(i) Financial assets at amortized cost 
 
Financial assets are classified and measured at amortized cost provided that they meet the following criteria: (i) the purpose of the 
Company’s business model is to maintain the asset to collect the contractual cash flows; and (ii) contractual conditions, on specific 
dates, give rise to cash flows only consisting in payments of principal and interest on the outstanding principal. 
 
(ii) Financial assets at fair value 
 
Financial assets are classified and measured at fair value through the consolidated statements of other comprehensive income if the 
financial assets are held in a business model whose objective is achieved by obtaining contractual cash flows and selling financial 
assets. However, financial assets are classified and measured at fair value through the consolidated statements of profit or loss if any 
of the aforementioned criteria is not met. 
 
2.4.6.1.2 Recognition and measurement 
 
Upon initial recognition, the Company measures a financial asset at its fair value plus, the transaction costs that are directly attributable 
to the acquisition of the financial asset.  
  
The Company reclassifies financial assets when and only when it changes its model for managing these assets.

(Amounts expressed in thousands of US Dollars, except otherwise indicated) 
 
F-25 
2.4.6.1.3 Impairment of financial assets 
 
The Company recognizes an allowance for Expected Credit Losses (“ECL”) for all financial assets not held at fair value through profit 
or loss. ECLs are based on the difference between contractual cash flows owed and all the cash flows that the Company expects to 
receive. 
 
For trade and other receivables, the Company calculates an allowance for ECL at each reporting date.  
 
Expected credit losses in trade and other receivables are estimated on a case-by-case basis according to the debtor’s history of 
noncompliance and an analysis of the debtor’s financial position, adjusted by the general economic conditions of the industry, its 
current assessment and a management forecast of conditions as of the reporting date. 
 
The Company recognizes an ECL of a financial asset when contractual payments are more than 90 days past due or when the internal 
or external information shows that it is unlikely that the pending contractual amounts be received.  
 
A financial asset is derecognized when there is no fair expectation to recover contractual cash flows. 
 
2.4.6.1.4 Offsetting of financial instruments 
 
Financial assets and liabilities are disclosed separately in the consolidated statement of financial position unless the following criteria 
are met: (i) the Company has a legally enforceable right to set off the recognized amounts, and (ii) the Company intends either to 
settle on a net basis or to realize the asset and settle the liability simultaneously. A right to set off is that available to the Company to 
settle a payable to a creditor by applying against it a receivable from the same counterparty.  
 
2.4.6.2 Financial liabilities and equity instruments 
 
Liabilities and equity instruments issued by the Company are classified as financial liabilities or equity according to the substance of 
the agreement and its definition. 
 
(i) Financial liabilities 
 
A contractual agreement is classified as a financial liability and is measured at fair value with changes in the consolidated statements 
of profit or loss and other comprehensive income. 
 
The financial liabilities are initially recognized at fair value and after that, at their amortized cost (using the effective interest method) 
or at fair value through the consolidated statements of profit or loss and other comprehensive income.  
 
The effective interest method is used in the calculation of the amortized cost of a financial liability and in the allocation of interest 
expense during the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments 
throughout the expected life of the financial liability. 
 
The Company derecognizes financial liabilities when obligations are discharged, cancelled or expired. The difference between the 
carrying amount of such financial liability and the consideration paid is recognized in the consolidated statements of profit or loss and 
other comprehensive income. 
 
When an existing financial liability is replaced by another one in terms that are substantially different from the original term or the 
terms of an existing liability change substantially, it results in the derecognition of the original liability and recognition of a new 
liability. The difference in the related accounting values is recognized in the consolidated statements of profit or loss and other 
comprehensive income. 
 
Borrowings are recognized initially at fair value, net of transaction costs incurred and collateral if any. Financial liabilities related to 
purchasing value units ("UVA" by Spanish acronym) are adjusted by the benchmark stabilization coefficient ("CER" by Spanish 
acronym) at each closing date, recognizing the effects on "Other financial income (expense)" under “Remeasurement in borrowings”.

(Amounts expressed in thousands of US Dollars, except otherwise indicated) 
 
F-26 
(ii) Equity instruments 
 
An equity instrument is any agreement that evidences an interest in the Company’s equity and is recognized for the amount of profit 
earned for the issuance of the equity instrument, net of direct issuance costs. 
 
(iii) Compound financial instruments 
 
The component parts of a compound instrument issued by the Company are classified separately as financial liabilities and equity 
instruments according to the substance of the contractual arrangements and the definitions of a financial liability and an equity 
instrument. An equity instrument is a conversion option that will be settled by the exchange of a fixed amount of cash or another 
financial asset for a fixed number of Company own equity instruments. 
 
The fair value of the liability component, if any, is estimated using the prevailing market interest rate for similar nonconvertible 
instruments. This amount is recorded as a liability at amortized cost using the effective interest method until extinguished upon 
conversion or at the instrument redemption date. 
 
A conversion option classified as equity is determined by deducting the liability component amount from the fair value of the 
compound instrument as a whole. It is recognized and included in equity, net of income tax effects, and it not subsequently remeasured. 
Moreover, the conversion option classified as an equity instrument remains in equity until the conversion option is exercised, in which 
case, the balance recognized in equity is transferred to another equity account. When the conversion option is not exercised at the 
redemption date of negotiable obligations, the balance recognized in equity is transferred to retained earnings. No profit or loss is 
recognized in the statement of profit or loss after the conversion or redemption of the conversion option. 
 
Transaction costs related to the issuance of compound financial instruments are allocated to liability and equity components in 
proportion to the allocation of gross proceeds. Transaction costs related to the equity component are recognized directly in equity. 
Transaction costs related to the liability component are included in the carrying amount of liability component and are amortized 
throughout the life of negotiable obligations using the effective interest method. 
 
2.4.7 Recognition of revenue from contracts with customers and other income  
 
2.4.7.1 Revenue from contracts with customers 
 
Revenue from contracts with customers related to the sale of Crude oil, Natural gas and Liquefied Petroleum Gas (“LPG”) is 
recognized when control of the assets is transferred to the customer.  
 
It is recognized for an amount of consideration to which the Company expects to be entitled in exchange for these assets, recognizing 
a credit under “Oil and gas accounts receivable (net of allowance for expected credit losses)” (Note 17).  
 
As of December 31, 2024, the normal credit term is 15 days for Crude oil sales and 57 days for Natural gas and LPG sales. The 
Company has reached the conclusion that it acts as principal in its revenue agreements because it regularly controls assets before 
transferring them to the customer. 
 
In Note 5.1 revenues was broken down by (i) product type and (ii) distribution channels. All Company revenue is recognized at a 
point in time. 
 
2.4.7.2 Contract balances 
 
Contract assets 
 
A contract asset is defined as the right to obtain a consideration in exchange for the goods or services transferred to the customer. 
Should goods or services be transferred before receiving the agreed-upon payment or consideration, a contract asset is recognized for 
the consideration received. The Company has no contract assets as of December 31, 2024 and 2023.

Contract liabilities 
 
A contract liability is the obligation to transfer goods or services to a customer for which the Company has received consideration. If 
the customer pays consideration before the Company transfers the goods or services, it recognizes a contract liability. When the 
Company fulfills its obligations according to the agreement, liabilities are recognized as revenue.

The cost of Crude oil inventories includes production expenses and other costs incurred in bringing the inventories to their present 
location and condition to make the sale. The cost of materials and spare parts is determined using the weighted average cost method. 
 
The net realizable value is the estimated selling price in the ordinary course of business less the estimated direct costs necessary to 
make the sale. 
 
The recoverable amount of these assets is assessed at each reporting date, and the resulting loss is recognized in the consolidated 
statements of profit or loss and other comprehensive income.

F-29 
2.4.11.2 Employee benefits  
 
The Company maintains a defined benefit plan described in Note 23. Which are related to a series of pension benefits that certain 
employees will receive at retirement, depending on factors, such as age, years of service and compensation. According to the 
conditions established in each plan, the benefit may consist of a single payment or payments supplementary to pension system 
payments. 
 
The cost of employee defined benefit plans is recognized periodically according to the contributions made by the Company. 
 
Labor cost liabilities are accumulated in the periods in which employees render the services that give rise to the consideration. 
 
The defined benefit obligation liability recognized in the consolidated statement of financial position is the present value of the defined 
benefit obligation, net of the fair value of plan assets. The defined benefit obligation is calculated at least as of every year-end by 
independent actuaries through the projected unit credit method. The present value of the defined benefit obligation is assessed 
discounting estimated future cash outflows using future actuarial assumptions on the demographic and financial variables that affect 
the assessment of such amounts.  
 
Actuarial profit and losses derived from changes in actuarial assumptions are recognized in other comprehensive income in the period 
in which they arise, and that shall not be reclassified to profit (loss) in subsequent years, likewise, the costs of past services are 
recognized immediately in the consolidated statements of profit or loss and other comprehensive income. 
 
2.4.12 Borrowing costs  
 
General or specific borrowings costs directly attributable to the acquisition, construction or production of assets that necessarily require 
a substantial period of time to be ready for their intended use or sale are added to the cost of these assets until they are ready for their 
intended use or sale. 
 
Income earned on the temporary investment of specific borrowings is deducted from borrowings costs eligible for capitalization. Other 
borrowings costs are accounted for in the period in which they are incurred. 
 
For the years ended December 31, 2024, 2023 and 2022, the Company has not capitalized borrowings costs because it had no 
qualifying assets, except for interest on the discount at present value on lease liabilities disclosed in Note 15.  
 
2.4.13 Provisions and contingent liabilities 
 
The Company recognizes provisions when the following conditions are met: (i) it has a present or future obligation as a result of a 
past event; (ii) it is probable that an outflow of resources will be required to settle the obligation; and (iii) a reliable estimate can be 
made. No provisions for operating future losses are recognized.  
 
In the case of provisions in which the time value of money is significant (as is the case of well plugging and abandonment and 
environmental remediation), these provisions are determined as the present value of the expected cash outflow for settling the 
obligation. Provisions are discounted at a rate that reflects current market conditions as of the date of the statement of financial position 
and, as the case may be, the risks specific to the liability. When the discount is applied, the increase in the provision due to the passage 
of time is recognized as a financial cost in the consolidated statements of profit or loss and other comprehensive income. 
 
2.4.13.1 Provision for contingencies 
 
Provisions for probable contingencies are measured at the present value of the amounts expected to be made to settle the present 
obligation, considering the best information available upon preparing the financial statements, based on the opinion of the Company’s 
legal counsel. Estimates are regularly reviewed and adjusted. 
 
Potential contingent liabilities are: (i) obligations from past events and whose existence will be confirmed only by the occurrence or 
nonoccurrence of uncertain future events not wholly within the entity’s control; or (ii) present obligations from past events that will 
not likely require an outflow of resources for its settlement, or which amount cannot be estimated reliably. These liabilities are 
disclosed in notes to the consolidated financial statements (Note 28).

F-30 
Contingent liabilities which probability is remote are not disclosed. 
 
2.4.13.2 Well plugging and abandonment provision 
 
The Company recognizes a provision for well pugging and abandonment when there is a legal or constructive obligation as a result of 
past events, it is probable that a cash flow will be required to settle the obligation, and the amount to be disbursed can be reliably 
estimated. 
 
In general, the obligation arises when the asset is installed, or the wells of land or environment at the site is modified. 
 
When the liability is initially recognized, the present value of estimated costs is capitalized, increasing the carrying amount of the 
assets related to the Crude oil and Natural gas extraction insofar as they were incurred for the development or construction of the well.  
 
The other provisions from an enhanced development or construction of the Crude oil and Natural gas production wells and facilities 
increase the cost of the related asset when the liability arises. 
 
The changes in the estimated time or cost of well plugging and abandonment are afforded a prospective treatment by booking an 
adjustment to the related provision and asset.  
 
2.4.13.3 Provision for environmental remediation 
 
The provision for environmental remediation is recognized when it is likely that a soil remediation be conducted, and costs may be 
estimated reliably. Generally, the timing of recognition of these provisions coincides with the commitment to a formal plan of action 
or, if earlier, on divestment or on closure of inactive sites. 
 
The amount recognized is the best estimate of the expenditure required to settle the obligation. To consider the time value of money, 
the recognized value is the present value of the estimated future expense. The effect of such estimate is recognized in the consolidated 
statements of profit or loss and other comprehensive income. 
 
It assesses if climate risks, including physical and energy transition risks, may have a major impact. If so, such risks are included in 
cash flows projected for estimating environment remediation costs (Note 2.4.19). 
 
2.4.14 Income tax  
 
Income tax for the period includes current and deferred income tax. Income tax is recognized in the consolidated statements of profit 
or loss and other comprehensive income except if it is related to items recognized in other comprehensive income or directly in equity. 
 
Current and deferred tax assets and liabilities were not discounted and are stated at nominal values. 
 
Income tax rates effective in Argentina and Mexico stand at 35% and 30% as of December 31, 2024, 2023 and 2022, respectively. 
For further information, see Note 16, 30.2 and 30.4.  
 
2.4.14.1 Current income tax 
 
The Company recognizes a current income tax liability as of every year-end, calculated based on effective laws enacted by the related 
tax authorities.  
 
The Company regularly assesses the positions adopted in the tax returns with respect to situations in which applicable tax regulations 
are subject to interpretation. When tax treatments are uncertain and it is probable that a tax authority will accept the tax treatment 
afforded by the Company, income tax is recognized according to their calculations and interpretations. If it is not considered likely, 
the uncertainty is shown using the most likely amount method or the expected value method depending on the method that best predicts 
the resolution to the uncertainty.

F-31 
The Company does business in several jurisdictions and is governed by effective laws enacted by each tax authority. The final 
assessment of current income tax for certain transactions and calculations is uncertain as there are cases in which tax regulations are 
subject to Company interpretation. 
 
2.4.14.2 Deferred income tax 
 
Deferred income tax is calculated using the liability method by comparing the tax bases of assets and liabilities and their carrying 
amounts in the financial statements to assess temporary differences.  
 
Deferred tax assets and liabilities are booked at nominal values and measured at the tax rates that are expected to apply to the period 
in which the liability is settled or the asset realized based on tax rates (and tax laws) enacted as of period-end. 
 
Deferred income tax assets and liabilities are only offset when there is a legally enforceable right and they are related to income tax 
levied by the same tax authority.  
 
Deferred income tax assets are recognized only insofar as it is probable that future taxable profit will be available and may be used to 
offset temporary differences. The carrying amount of deferred tax assets is reviewed at the end of each reporting period and reduced 
to the extent that it is no longer probable that sufficient profit will be available to allow all or part of the asset to be recovered. 
 
2.4.15 Share-based payments  
 
The Company grants to some employees shared-based compensation; whereby employees receive as consideration for equity 
instruments (equity-settled transactions).  
 
Equity-settled transactions 
 
The cost of equity-settled transactions is determined by the fair value at vesting date using a proper valuation method (Note 31). 
 
Such cost is recognized in the consolidated statements of profit or loss and other comprehensive income in “General and administrative 
expenses” under “Share-based payments” along with the related capital increase during the period in which the service is rendered 
and performance conditions. 
 
On March 22, 2018, the Company approved a Long-Term Incentive Plan ("LTIP") whose goal is to attract and retain talented persons 
such as officers, directors, employees and consultants. The LTIP includes the following mechanisms for rewarding and retaining key 
personal: 
 
(i) Stock option plan (“SOP”)  
 
The stock option plan grants the participant the right to buy a number of shares over certain term. The cost of the equity-settled plan 
is measured at grant date considering the specific terms and conditions. The equity-settled compensation cost is recognized in the 
consolidated statements of profit or loss and other comprehensive income in “General and administrative expenses” under “Share-
based payments”. 
 
(ii) Restricted stock (“RS”)  
 
The restricted stock plan grants the participant additional benefits are met through a stock option plan which has been classified as an 
equity-settled share-based payment. The cost of the equity-settled plan is measured at grant date considering the specific terms and 
conditions. The equity-settled compensation cost is recognized in the consolidated statements of profit or loss and other comprehensive 
income in “General and administrative expenses” under “Share-based payments”.

F-32 
(iii) Performance restricted stock ("PRS")  
 
The performance restricted stock grants the participant, which entitle them to receive PRS after having reached certain performance 
targets over a service period. PRS are classified as equity-settled share-based payments. The cost of the equity-settled plan is measured 
at grant date considering the specific terms and conditions. The equity-settled compensation cost is recognized in the consolidated 
statements of profit or loss and other comprehensive income in “General and administrative expenses” under “Share-based payments”. 
 
2.4.16 Investments in associates 
 
An associate is an entity over which the Company has significant influence, being the power to participate in the financial and 
operating policy decisions of the associate but not control or join control over it. The considerations regarding control and significant 
influence are similar to those made by the Company in relation to its subsidiaries (Note 2.3.1). 
 
Investments are initially recognized at acquisition cost and then using the equity method whereby interests are recognized in profit or 
loss and in equity. The equity method is used as from the date when the significant influence over the associates is exercised. 
 
The associates’ financial statements were prepared using the same policies employed in preparing these consolidated financial 
statements. 
 
The Company’s interests in the associates’ net profits or losses, after acquisition, are recognized in the statements of profit or loss and 
other comprehensive income. 
 
As of December 31, 2024 and 2023, the amount of investments in associates was 11,906 and 8,619, respectively. 
 
2.4.17 Biological assets 
 
Biological assets are measured at initial recognition, and at the end of each reporting period, at fair value less estimated costs to sell 
at the point of harvest or collection. 
 
Changes in fair value at initial or subsequent recognition are recognized in the period in the consolidated statement of profit or loss 
and other comprehensive income.  
 
As of December 31, 2024, the Company has biological assets for 10,027, mainly related of tree plantations, and its fair value less costs 
to sell are similar to replacement cost, as they are at the initial growth cycle. 
 
Tree plantations are classified as non-current biological assets because they are not expected to be harvested within the next 12 months.  
 
2.4.18 Going concern  
 
The Board oversees the Group’s cash position regularly and liquidity risk to ensure that there are sufficient funds to meet expected 
financing, operating and investing requirements.  
 
Considering the macroeconomic context, the result of operations and the Group’s cash position as of December 31, 2024 and 2023, 
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 consolidated financial statements were prepared on a going concern basis.

2.4.19 Climate-Related Matters 
 
The Company frequently assesses the potential impact of climate-related matters in the estimates and assumptions used as basis for 
some items in the financial statements.  
 
Even though the Company considers that its business model will continue to be feasible after transition to a low-carbon economy, 
climate-related matters increase uncertainty in the following estimates and assumptions:  
 
(i) Useful life of property, plant and equipment: upon reviewing the expected useful life and residual value of assets, the Company 
considers climate-related matters and the legislation that may restrict the use of assets or require major capital expenditure (Note 
2.4.2.1).   
 
(ii) Impairment of long -lived assets and business credit: upon assessing the recoverable value of these assets, the Company considers 
climate-related matters, and climate change regulations (Note 3.2.1 and 3.2.2).  
 
(iii) Environmental remediation liabilities: the Company considers the potential impact of climate-related matters upon estimating 
future decommissioning costs (Note 2.4.13.3).  
 
Even though the Company considers climate-related matters have no major impact in the consolidated financial statements, it regularly 
assesses relevant changes and developments. 
 
2.5 Regulatory framework  
 
A- Argentina  
 
2.5.1 Regulatory framework for oil and gas activity  
 
In Argentina, oil and gas exploration, exploitation and trade is governed by Law No. 17,319 and its amendments (“Argentine 
Hydrocarbons Law”), which establishes the regulatory framework for the exploration, exploitation, transportation and marketing of 
hydrocarbons (oil and natural gas) in the country.  
 
The main modifications to the Argentine Hydrocarbons Law are detailed below: 
 
(i) Law No. 27,007: 
 
- 
It sets the terms for exploration permits and operating and transport concessions, distinguishing between conventional and 
unconventional concessions, the continental platform and territorial marine reserves; 
 
- 
The 12% payable as royalties are still effective to the grantor by operating concessionaires on the extraction of liquid hydrocarbon 
byproducts in wellheads and Natural gas production. In case of an extension, additional royalties will be paid up to 3% up to a 
maximum 18% for the following extensions; and 
 
- 
It prevents the Argentine government and provinces from reserving new areas in the future in favor of public or mixed companies 
or entities, regardless of their legal type. Therefore, the agreements entered into by provincial companies for the exploration and 
development of reserved areas before the amendment are safeguarded. 
 
However, the Province of Neuquén has its own Hydrocarbon Law No. 2,453. Hence, the Company’s assets in the Province of Neuquén 
are governed by such law, whereas the remainder assets located in the Provinces of Río Negro and Salta follow Law No. 17,319, and 
its subsequent amendments.

F-34 
(ii) Law No. 27,742: 
 
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 law’s main objective is deregulating the Argentine economy and adjust the state’s operation and structure; declaring a public 
administrative, economic, financial, and energetic emergency for a year, and grant the Argentine Executive (“PEN” by Spanish 
acronym) delegated legislative powers, as main measures. 
 
Regarding the main amended to the Argentine Hydrocarbons Law, as follows: 
 
- 
Eliminates the concept of hydrocarbon self-supply existing at the time, with the objective of maximizing corporate profits from 
the exploitation of resources; 
 
- 
Establishes that the Executive (National or Provincial, as the case may be) may grant storage permits and authorizations for 
hydrocarbon processing, under the requirements and conditions set forth by the Argentine Hydrocarbons Law; 
 
- 
Grants producers rights to trade, transport, and industrialize hydrocarbons and by-products, while prohibiting the National 
Executive from intervening or setting prices;  
 
- 
Establishes the free export and import of hydrocarbons and by-products, eliminating the Department of Energy’s authority to 
challenge export permits;  
 
- 
Amends the acquisition system and terms for unconventional concessions following the reconversion of conventional concessions; 
 
- 
Authorizes the regulatory authority to grant concessions for terms other than those established in Argentine Hydrocarbons Law;  
 
- 
Amends the extension system for new concessions; 
 
- 
Mandates that new concessions be awarded through a bidding process upon expiration of existing concessions.  
 
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. 
 
The Bases Law had no significant impact on these consolidated financial statements.  
 
2.5.2 Exports Increase Program  
 
On October 3, 2023, the Department of Energy (“SE” by Spanish acronym) through Resolution No. 808/23, established that the 
exporters of Crude oil, Natural gas and by-products (that meet certain conditions) may receive 25% of the funds obtained from exports 
through securities acquired in foreign currency and sold in local currency.  
 
On October 23, 2023, the PEN, through Necessity and Urgency Decree (“DNU” by Spanish acronym) No. 549/23, set forth the Export 
Increase Program, by virtue of which 30% of the funds obtained from exports may be received through securities market, effective 
through November 17, 2023.

F-35 
On November 20, 2023, the PEN through DNU No. 597/23 amended the percentages setting 50% as the amount obtained from export 
to be received through the securities market, effective until December 10, 2023. It also ratified the exporters should pay duties, taxes 
and other items based on the exceptional and temporary countervalue related to these payments. 
 
On December 13, 2023, the PEN through DNU No. 28/23 amended the percentages setting 20% as the amount to be received through 
the securities market in foreign currency, currently in place. 
 
For the years ended December 31, 2024, and 2023, the Company recognized a gain of 45,201 and 81,232 in “Other operating income” 
under “Gain from Exports Increase Program” (Note 10.1). 
 
2.5.3 Gas market 
 
2.5.3.1 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 PEN approved Gas IV Plan, whereby it declared that the 
promotion of Natural gas production is both a matter of public interest and a priority. 
 
On December 15, 2020, through Resolution No. 391/2020, the SE awarded volumes and prices, for which the Company entered into 
agreements with Compañía Administradora del Mercado Mayorista Eléctrico S.A. (“CAMMESA”), Integración Energética Argentina 
S.A. (“IEASA”) and other distribution to supply Natural gas for electric power generation and residential consumption, respectively. 
 
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 22, 2022, through Resolution No. 860/2022, of the SE, the Company, through its subsidiary Vista Argentina, was 
awarded a base volume of 0.86 million cubic meters per day (“Mcm/d”) at an annual average price of 3.29 USD/MMBTU (Millions 
of British Themal Units (“MMBTU”)), applicable until December 31, 2024. 
 
The Company was granted a permit by the SE to export Natural gas to Chile according to the following volumes:  
(i) 
0.15 Mcm/d for the period elapsed from January through April 2022;  
(ii) a variable volume for May through September 2022; and 
(iii) 0.45 Mcm/d for the period elapsed from October 2022 through April 2023. 
 
On April 19, 2023, through Resolution No. 265/2023 of the SE, the base volume awarded to Vista was increased to 1.14 Mcm/d, 
maintaining the annual average price of 3.29 USD/MMBTU, applicable for a 4-year period as from January 1, 2025.  
 
The Company was granted a permit by the SE to export Natural gas to Chile according to the following volumes:  
 
(i) 
0.02 Mcm/d for the period elapsed from July through September 2023;  
(ii) 0.43 Mcm/d for the period elapsed from October 2023 through April 2024;  
(iii) 0.17 Mcm/d for the period elapsed from May through September 2024; 
(iv) 0.43 Mcm/d for the period elapsed from October through December 2024;  
(v) 0.17 Mcm/d for the period elapsed from January through April 2025; 
(vi) 0.15 Mcm/d for the period elapsed from May through September 2025; and 
(vii) 0.17 Mcm/d for the period elapsed from October through December 2025. 
 
For the years ended December 31, 2024 and 2023, the Company received a net amount of 3,839 and 5,189, respectively.  
As of December 31, 2024 and 2023, the receivables related to such plan stand at 3,007 and 1,245, respectively (Note 17).

2.5.4 Royalties and others 
 
(i) Royalties  
 
As mentioned in Note 2.5.1, royalties are governed by Law No. 17,319, as amended, and are calculated by applying 12% to the selling 
price after discounting certain expenses with the purpose of taking the value of the cubic meter of Crude oil, Natural gas and LPG to 
wellhead prices.  
 
(ii)  Export duties 
 
Law No. 27,541, issued in December 2019, sets the maximum rate for export duties of hydrocarbons and mining at 8%.  
 
Royalties and export duties are recognized in the consolidated statements of profit or loss and other comprehensive income in “Cost 
of sales” under “Royalties and others” (Note 6.3).

Mexico 
 
2.5.5 Exploration and production activities regulatory framework 
 
In 2013, Mexico introduced several amendments to Mexico’s Constitution that led to opening Crude oil, Natural gas and energy to 
private investments. As part of the energy reform, Petróleos Mexicanos (“PEMEX” by Spanish acronym) transformed from a 
decentralized public entity into a productive state-owned enterprise. Mexico’s Hydrocarbon Law, that preserves state property over 
subsoil hydrocarbons but allows private companies to assume responsibility for hydrocarbons once extracted.  
 
These amendments also allow private sector entities to obtain permits for the processing, refining, marketing, transportation, storage, 
import and export of hydrocarbons. 
 
Therefore, empowers private-sector entities to request the granting of a permit from Mexico’s Energy Regulatory Commission (“CRE” 
by Spanish acronym) to store, transport, distribute, trade and sell hydrocarbons. In addition, private-sector entities can import or export 
hydrocarbons subject to a permit issued by Mexico’s Ministry of Energy (the “SENER” by Spanish acronym). 
 
The National Hydrocarbon Commission (the “CNH” by Spanish acronym) conducts rounds of bid granting agreements to oil 
companies and business consortia. It interacts with PEMEX and private companies and manage all exploration and production 
(“E&P”) agreements. The agreements for the transport, storage, distribution, compression, liquefaction, decompression, 
regassification, trade and sale of Crude oil, oil byproducts and Natural gas are granted by the CRE. 
 
In May 2021, Mexican Hydrocarbons Law Reforms (the “Reforms”) was published in the Official Bulletin. In general, the Reforms 
affect the permit system under Mexican Hydrocarbon Law by granting enhanced powers to the SENER and the CRE to grant, review, 
and revoke the different permits under such law. The Reforms also regain public control of the Mexican oil trading sector. 
 
2.5.6 Royalties and others 
 
The consideration payable to the Mexican government will be made up of: 
 
(i) Contractual installment for exploration phase 
 
It applies to the areas that do not have a development plan approved by the CNH and it is calculated monthly using the instalment 
established for each square kilometer comprising the areas covered by the contract.

(Amounts expressed in thousands of US Dollars, except otherwise indicated) 
 
F-37 
(ii) Royalties 
 
Royalties apply to the concessions’ total output and are calculated by applying the contractual percentage to the selling price.  The 
contractual percentage is 45%, which will be adjusted as established in the contract. There is also a variable royalty, which will be 
applied to each type of hydrocarbon by applying the related rate to the selling price. Royalties are included in the consolidated 
statements of profit or loss and other comprehensive income in “Cost of sales” under “Royalties and others” (Note 6.3). 
 
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 
6.3), which was previously included in “Revenues from contract with customers”. 
 
The comparative information for the year ended December 31, 2022, has been reclassified to ensure consistent filing with the 
consolidated financial statements as of December 31, 2024 and 2023. 
 
“Revenues from contract with customers” and “Royalties and others” increased by 43,840 for the year ended December 31, 2022. 
 
These changes had no effect on the net profit for the year ended December 31, 2022. 
 
Note 3. Significant accounting judgements estimates and assumptions 
 
Preparing the consolidated financial statements requires that the Company make future judgments and estimates, apply significant 
accounting judgments and make assumptions that affect the application of accounting policies and the figures for assets and liabilities, 
revenue and expenses.  
 
The estimates and judgments used in preparing the consolidated financial statements are constantly evaluated and are based on the 
historical experience and other factors considered to be fair in accordance with current circumstances. Future profit (loss) may differ 
from the estimates and evaluations made as of the date of preparation of these consolidated financial statements. 
 
3.1 Significant judgments in the application of accounting policies  
 
Below are the significant judgments other than those involving estimates (Note 3.2) that Management made and that have a material 
impact on the figures recognized in the consolidated financial statements. 
 
3.1.1 Contingencies  
 
The Company is subject to several claims, trials and other legal proceedings that arose during the ordinary course of business. The 
Company’s liabilities with respect to such claims, trials and other legal proceedings cannot be estimated with an absolute certainty.  
Therefore, the Company periodically reviews each contingency status and assesses the potential liability, employing the criteria 
mentioned in Note 22.3; hence, Management makes estimates mainly with the legal counsel’s assistance. 
 
Contingencies include pending lawsuits for potential damage or third-party claims in the Company’s ordinary course of business and 
claims from disputes related to the interpretation of applicable legislation.  
 
3.1.2 Environmental remediation  
 
The costs incurred in limiting, neutralizing or preventing environmental pollution are capitalized only if at least one of the following 
conditions is met: (i) these costs are related to security improvements; (ii) environmental pollution risk is prevented or limited; or (iii) 
the costs incurred in preparing assets for sale and the carrying amount (which considers these costs) of these assets does not exceed 
the related recovery value. 
 
The liabilities related to future remediation costs are booked when, based on environmental assessments, the likelihood of occurrence 
of these liabilities is high and costs may be reasonably estimated. The actual recognition and amount of these provisions is generally 
based on the commitments acquired by the Company to realize them, such as an approved remediation plan or the sale or disposal of 
an asset. The provision is recognized on the basis that the future remediation commitment will be required.

2024, 2023 and 2022  
(Amounts expressed in thousands of US Dollars, except otherwise indicated) 
 
F-38 
The Company measures liabilities based on the best estimate of the present value of future costs using the information currently 
available and by applying current environmental laws and regulations and the Company’s existing environmental policies. 
 
3.1.3 Business combinations  
 
The acquisition method implies the measurement at fair value of identifiable assets acquired and liabilities assumed in a business 
combination at acquisition date. 
 
The Company determines that it has acquired a business when the acquired set of activities and assets include an input and a substantive 
process that together significantly contribute to the ability to create an output. The acquired process is considered substantive if it is 
critical to the ability to continue producing outputs, and the inputs acquired include an organized workforce with necessary skills, 
knowledge or experience to perform those processes or else it significantly contributes to the ability to produce outputs and is 
considered unique or scarce or cannot be replaced without significant cost, effort or delay in the ability to continue producing outputs. 
In cases where an oil and gas property acquisition transaction does not compliance the above conditions, the Company considers that 
it must be recognized as an asset acquisition. 
 
When the Company determines that it has acquired a business, to determine the fair value of identifiable assets, the Company uses the 
valuation approach that is most representative for each asset. These methods are the (i) income approach through indirect cash flows 
(net present value of expected future cash flows) or through the multi-period excess earnings method; (ii) cost approach (replacement 
value of the asset adjusted by loss due to physical impairment, functional and economic obsolescence); and (iii) market approach 
through a comparable transaction method. 
  
Also, to determine the fair value of liabilities assumed, the Company considers the likelihood of cash outflows that will be required 
for each contingency and calculates the estimates with the legal counsel’s assistance based on available information and the litigation 
and resolution/settlement strategy. 
 
Management significant judgment is required to choose the approach to be used and estimate future cash flows. Actual cash flows and 
values may differ significantly from expected future cash flows and the related values obtained through the aforementioned valuation 
techniques. 
 
As of December 31, 2024, 2023 and 2022, the Company has not registered any business combinations. 
 
3.1.4 Joint arrangements  
 
The Company assesses whether it has joint control on an arrangement, analyzing the activities and decisions about these relevant 
activities that require unanimous consent. The Company determined that the relevant activities for joint arrangements are those related 
to operating decisions, including the approval of the annual budget and the approval of service suppliers. The considerations made to 
assess joint control are the same as those needed to determine control on subsidiaries as established in Note 2.3.1. 
 
Judgment is also required to classify a joint arrangement. Which requires that the Company assess its rights and obligations under the 
agreement.  
 
3.1.5 Functional currency  
 
The functional currency of the Company and its subsidiaries is the USD (Note 2.4.5.1), the currency of the primary economic context 
in entity operates. To determine the functional currency, the Company makes judgments. The Company reconsiders the functional 
currency in the event of a change in conditions that may determine the primary economic context.

F-39 
3.2 Key sources of uncertainty in estimates  
 
Below are the main estimates that entail significant impact in the Company’s assets, liabilities and profit or loss: 
 
3.2.1 Impairment of goodwill  
 
Goodwill is reviewed annually for impairment or more frequently if there are events or changes in circumstances showing that the 
recoverable amount of the CGU related to goodwill should be analyzed. Whether goodwill is impaired is assessed by considering 
the recoverable amount of the CGUs to which it is allocated. Impairment is recognized when the recoverable amount of the CGU is 
lower than its carrying amount (including goodwill). 
 
As of December 31, 2024 and 2023, the Company has goodwill for 22,576 (Note 14) related to the initial business combination. 
 
The assessment of whether goodwill of a CGU or group of CGUs is impaired involves Management estimates on highly uncertain 
matters, including the assessment of the appropriate group of CGUs for goodwill impairment testing. The Company supervises 
goodwill for internal management purposes based on its only business segment. 
 
Upon testing goodwill for impairment, the Company uses the approach described in Note 3.2.2. 
 
No goodwill impairment losses were recognized as of December 31, 2024, 2023 and 2022. 
 
3.2.2 Impairment of long-lived assets other than goodwill  
 
Long-lived 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 CGUs.  
 
In Argentina, oil and gas properties were grouped as follow:  
 
- As of December 31, 2024 and 2023, (i) operated exploitation concessions of unconventional oil and gas; and (ii) non-operating 
concessions of conventional oil and gas.  
 
 
- As of December 31, 2022, (i) operated exploitation concessions of conventional oil and gas; (ii) operated exploitation concessions 
of unconventional oil and gas; and (iii) non-operating concessions of conventional oil and gas.  
 
The Company also identified only 1 CGUs in Mexico: (i) operated exploitation concessions of conventional oil and gas, as of 
December 31, 2024, 2023 and 2022.  
 
To assess whether there is evidence that a CGU may be impaired, external and internal sources of information are analyzed, provided 
that the events or changes in circumstances show that the book value of an asset or CGU may not be recovered. Some examples of 
these events are changes in the Group’s business plans, physical damage testing, or, in the case of oil and gas assets, decrease of 
estimated reserves or increases in estimated future development expenses or dismantling costs, the behavior of Crude oil international 
prices and demand, the regulatory framework, expected capital investments and changes in demand. Should there be an indication of 
impairment, the Company estimates the recoverable amount of the asset or CGU. 
 
The recoverable amount of a CGU is the highest of (i) its fair value less selling price or costs of disposal, and (ii) its value in use. 
When the carrying amount of a CGU exceeds its recoverable amount, the CGU is deemed impaired, and it is reduced to its recoverable 
amount. Due to the nature of the Company’s activities, the information on the fair value less selling price of an asset or CGU is usually 
difficult to obtain unless negotiations are underway with potential buyers or similar transactions. Consequently, unless otherwise 
stated, the recoverable amount used in impairment testing is the value in use. 
 
The value in use of each CGU is estimated using the present value of future net cash flows. Each GGU’s business plans, which are 
approved annually by the Company, are the main sources of information to determine the value in use.

F-40 
As the initial step in drafting these plans, the Company establishes different assumptions on market conditions, such as Crude oil, 
Natural gas and LPG prices. These assumptions consider existing prices, the balance between global supply and demand of Crude oil 
and Natural gas. Upon assessing the value in use, estimated future cash flows are adjusted to consider the specific risks of the group 
of assets and are discounted at present value using a discount rate that reflects the current market assessments of the time value of 
money.  
 
The Company assesses whether there is an indication that previously recognized impairment losses have reversed or decreased as of 
each reporting date. A previously recognized impairment loss is reversed only if here has been a change in the estimates used in 
determining the recoverable amount of the asset. 
 
The assessment of whether an asset or CGU is impaired and to which extent involves Company estimates on highly uncertain issues 
such the effects of inflation on exploitation expenses, discount rates, production profiles, reserves and resources and commodity future 
prices. It requires that assumptions be made when assessing the proper grouping of items of property, plant and equipment in a CGU. 
Actual cash flows and values may differ significantly from expected future cash flows and related amounts obtained using discount 
techniques, which could create major changes in the accounting values of the Group’s assets. 
 
As of December 31, 2024, the Company did not identify indications of reversal or impairment related with goodwill and long -lived 
assets other than goodwill in Argentina. However, the Company identified reversal of impairment indicators to the CGU in Mexico, 
mainly resulting from the recovery of the local price of Natural gas. 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, 2024 the Company recorded a reversal of impairment of 4,207 
related to the CGU operated exploitation concessions of conventional oil and gas exploration and production in Mexico. 
 
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 to goodwill and long-lived assets other 
than goodwill in Argentina and Mexico.

(1) The prices correspond to Brent and Maya, for Argentina and Mexico, respectively.  
 
(i) Discount rates: Discount rates represent the present market value of the Company’s specific risks considering the time value of 
money and the individual risks of the underlying assets that have not been considered in cash flow estimates. The discount rate is 
calculated based on the Company’s specific circumstances and is derived from the weighted average cost of capital (“WACC”) with 
the proper adjustments to reflect risks and determine the rate before taxes. The income tax rate used is the tax rate effective in Argentina 
and Mexico standing at 35% and 30%, respectively. The WACC considers the cost of debt and cost of capital and considered public 
market data of certain companies deemed comparable (“comparable companies”) based on the industry, region and main activity. 
 
(ii) Prices of Crude oil, Natural gas and LPG: Expected commodity prices are based on Management estimates and available market 
data. 
 
The Company considered discounts for Crude oil prices based on the quality of the Crude oil produced in each CGU. The dynamics 
of the domestic Crude oil and liquid fuels markets in Argentina and Mexico are also considered. The changes in Brent and Maya 
prices was estimated using the average market analysis forecasts. 
 
To forecast the local price of Natural gas used the average price received from gas sales in each CGU. Natural gas prices are adjusted 
by the calorific value of gas produced in each CGU. 
 
The Company’s long-term assumption for Crude oil prices reflects the judgment that the market can produce enough oil to meet global 
demand sustainably. 
 
(iii) Production and reserve volumes: the production level and the reserves is based on the reports certificated by external consultants 
and different risk factors were also applied to determine the expected value of each type of reserve (Note 32). 
 
Sensitivity to changes in assumptions  
 
Regarding the assessment of the value in use as of December 31, 2024, and 2023, 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 decrease its 
recoverable amount, except for the following:

Notes to the consolidated financial statements as of December 31, 2024 and 2023, and for the years ended December 31,

(Amounts expressed in thousands of US Dollars, except otherwise indicated) 
 
F-42 
As of December 31, 2024, and 2023, the net carrying amount of property, plant and equipment, other intangible assets and right-of-
use assets is disclosed in Note 13, 14 and 15, respectively. 
 
3.2.3 Current and deferred income tax  
 
3.2.3.1 Current income tax 
 
The Company recognizes a current income tax liability as of every year-end, calculated according to effective laws enacted by the 
related tax authorities and, if necessary, provisions are recognized based on the amounts payable to tax authorities. However, there 
are some transactions and calculations which tax assessment is uncertain as sometimes tax regulations are subject to Company 
interpretation.  
 
When tax treatments are uncertain and it is probable that a tax authority will accept the tax treatment afforded by the Company, income 
tax is recognized according to their calculations and interpretations. If it is not considered likely, the uncertainty is shown using the 
most likely amount method or the expected value method depending on the method that best predicts the resolution to the uncertainty. 
 
3.2.3.2 Deferred income tax 
 
Deferred tax assets are reviewed as of each reporting date and are amended according to the probability that the tax base allow the 
total or partial recovery of these assets. Upon assessing the recognition of deferred tax assets, the Company considers whether it is 
probable that some or all assets are not realized, which depends on the generation of future taxable profit in the periods in which these 
temporary differences become deductible. To this end, the Company considers the expected reversal of deferred tax liabilities, future 
taxable profit projections and tax planning strategies. 
 
The assumptions on the generation of future taxable profit depend on the Company estimates of future cash flows, which are affected 
by sales and production volumes; Crude oil and Natural gas prices; operating costs; well plugging and abandonment costs; capital 
expenses; and the judgment on the application of tax laws effective in each jurisdiction.  
 
Insofar as future cash flows and taxable profit substantially differ from the Group’s estimates, the Group’s capacity to realize net 
deferred tax assets booked at reporting date may be affected. Moreover, future changes in the tax laws in the jurisdictions in which 
the Group operates may hinder its capacity to obtain tax deductions in future periods. 
 
3.2.4 Well plugging and abandonment  
 
Well plugging and abandonment at the end of the exploitation concession term requires that Company Management calculate the 
number of wells, the long-term costs of abandonment and the remaining time until abandonment. The technological, cost, policy, 
environment and safety issues change constantly and may give rise to differences between actual costs and future estimates. 
 
Well plugging and abandonment estimates should be adjusted by the Company at least annually or in the event of changes in the 
assessment criteria assumed. 
 
Well plugging and abandonment liabilities stand at 32,438 and 15,287, as of December 31, 2024, and 2023, respectively (Note 22.1).  
 
3.2.5 Oil and gas reserves  
 
Oil and gas items of property, plant and equipment are depreciated using the UDP method over total proved reserves (developed and 
not developed as applicable). Proved oil and gas reserves are those quantities of Natural gas, Crude oil, and LPG which by analysis 
of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date 
forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations.  
 
The useful life of each property, plant and equipment asset is assessed at least annually considering the physical limitations of the 
goods and the assessments of the economically recoverable reserves in the field in which the asset is located.

Notes to the consolidated financial statements as of December 31, 2024 and 2023, and for the years ended December 31, 
2024, 2023 and 2022  
(Amounts expressed in thousands of US Dollars, except otherwise indicated)

There are several uncertainties in the estimate of proved reserves and future production plans, development costs and prices, including 
several factors that are beyond the Company’s control. In estimating reserves involves a certain degree of uncertainty and depend on 
the quality of the engineering and geological data available as of the estimate date and their interpretation and judgment. 
 
Reserve estimates are adjusted by changes in the assessment criteria or at least annually. These reserves are based on the estimates 
certified annually by independent reserve engineering consultant. 
 
The Company uses the information obtained from the reserve calculation in determining the depreciation of assets used in oil and gas 
areas, and in assessing their recoverability (Note 3.2.1, 3.2.2, 13 and 32).  
 
3.2.6 Share-based payments 
  
The fair value estimate of share-based payments requires the determination of the most appropriate valuation model, which depends 
on the terms and conditions of the award. This estimate also requires the assessment of the most appropriate input for the valuation 
model, including the remaining life of stock options, and the shares volatility. 
 
To measure the fair value of share-based payments at grant date, the Company employs the Black & Scholes model. The carrying 
amount, hypotheses and models used in estimating the fair value of transactions involving share-based payments are disclosed in Note 
31. 
 
3.2.7 Agreement signed with Aconcagua related to conventional assets (“transfer of conventional assets”) 
 
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”).  
 
The Transaction consists of a two-phase operation as described below: 
 
(i) The First Phase or Operating Period, which became effective on March 1, 2023, (“Effective Date”) and will remain in place until 
the “Closing Date”, which will be: (i) the date when Vista Argentina has received 4 million barrels of Crude oil and 300 million 
standard cubic meters (m3) of Natural gas (9,300 kilocalories per m3); or (ii) February 28, 2027 (“Deadline"), whichever comes 
first.  
 
If Aconcagua fails to meet the aforementioned point (i) and prior of the Deadline, must pay VISTA the undelivered production 
according to the average price of the Neuquén Basin for the last 12 months. 
 
(ii) The Second Phase will begin on Closing Date, and Vista Argentina and Aconcagua will request the Provinces of Río Negro and 
Neuquén (“the Provinces”) to approve the assignment of the Concessions. Thus, the Second Phase will end when the Concessions 
are transferred to Aconcagua through province approval and the Transaction will then be formalized. 
 
Under the terms of the Transaction, during the Operating Period, Vista Argentina maintains the ownership of the Concessions, and 
Aconcagua: (i) pays 26,468 in cash (10,000 on February 15, 2023, (“Signature Date”) and 10,734 and 5,734 in March 2024 and 2025, 
respectively);  (ii) will operate the Concessions on an as is where is basis, and (iii) pays 100% of Vista’s share capex, operating cost, 
as well as assumes any other cost, including royalties and taxes related to the operation of Concessions. 
 
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. 

VISTA ENERGY, S.A.B. DE C.V.  
Notes to the consolidated financial statements as of December 31, 2024 and 2023, and for the years ended December 31, 
2024, 2023 and 2022  
(Amounts expressed in thousands of US Dollars, except otherwise indicated) 
 
F-44 
 
Finally, if Aconcagua fails to comply with its obligations, which either in part or in full exceed 250, Vista Argentina may regain 
control of the Concessions. 
 
As of December 31, 2023, as a consequence of the Transaction, the Company received 10,000 in cash; and recognized: (i) an initial 
accounts receivable for a total amount of  205,730 in “Trade and other receivables” under “Receivable related to the transfer of 
conventional assets” (Note 17); (ii) a disposal of 120,529 and 5,542 in “Property, plant and equipment” and “Goodwill”, 
respectively (Note 13 and 14), and (iii) a gain of 89,659 in “Other operating income” under “Gain related to transfer of conventional 
assets” (Note 10.1) resulting from the difference between the initial consideration and the residual value deletion of net assets 
included in the Transaction. 
This consideration is related to the committed funds and the initial credit recognized, which is equivalent to the discounted value of 
the agreed-upon volumes of Crude oil, Natural gas and LPG to be received during the Operating Period. For the valuation of 
receivables, the Company has estimated the terms and costs of supplying these volumes and the discount rate applicable. 
 
As of December 31, 2024, the Company received 10,734 related with the Transaction. 
 
For the years ended December 31, 2024 and 2023, the Company recognized 33,570 and 27,539 in the consolidated statement of profit 
or loss under “Other non-cash costs related to the transfer of conventional assets”, mainly related to the cost related for supplying the 
volumes of Crude oil, Natural gas and LPG by Aconcagua under the agreement, which were discounted from the initial credit 
recognized for the transaction. 
 
Note 4. Segment information  
 
The 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, 2024, 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 consolidated financial statements.

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

Basic earnings per share 
4.979  
4.237
3.068
 
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, 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, no 
dilution effect is booked, as diluted earnings per share is equal to basic earnings per share.

deductions of nonmonetary assets; and (iii) the accumulative tax losses not recognized in the period.

(4) As of December 31, 2024, includes 13,200 with Aconcagua, related to the extension of the concessions (Note 28.5). As detailed in Note 3.2.7, Aconcagua 
assumes all obligations and payables from applicable Concessions until the end of the Operating Period; however, the Company maintains 100% ownership. 
 
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, 2024, in general accounts receivable has a 15-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 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, 2024 and 2023 the provision for expected credit losses was recorded for 41 and 52 respectively. 
 
The changes in the provision for expected credit losses of trade and other receivables are as follows:

(1) Subscribed in USD, payable in ARS at the exchange rate applicable on maturity date. 
(2) As of December 31, 2024 the Company pre-settled ON XI and XIV. 
(3) On May 29, 2023, the Company settled ON VII by: (i) issuing additional ON XVI for 40,785 (which generated no cash flows); and (ii) paid remind principal 
and interest. The Company recognized 819 related to the loss from the issuance of the swap mentioned (Note 11.3). 
(4) The carrying amounts of ONs XVII; XVIII; XXI and XXIII include 1,200, 2,500, 2,650 and 20,000, respectively, of ONs repurchased by the Company.  
(5) See Note 1.2.1.  
As of December 31, 2024, certain Vista Argentina’s ON contains covenants that will limit its ability to, among other things: (i) incur additional indebtedness 
and guarantee indebtedness; (ii) pay dividends or make other distributions or repurchase or redeem our capital stock; (iii) prepay, redeem or repurchase 
certain debt; (iv) make loans and investments; (v) enter into agreements that restrict its subsidiaries’ ability to pay dividends, transfer assets or make 
intercompany loans; (vi) incur or permit to exist certain Liens; (vii) sell, transfer or otherwise dispose of assets; (viii) enter into sale and lease-back 
transactions; (ix) enter into transactions with affiliates; and (x) consolidate, amalgamate, merge. 
With respect to the limitation on incurrence of indebtedness, Vista Argentina will not, and will not permit any of its subsidiaries, if any, to, directly or 
indirectly, incur any indebtedness. The company or any of its subsidiaries may incur indebtedness if, at the time of and immediately after giving pro forma 
effect to the incurrence thereof and the application of the net proceeds therefrom: 
(i) its Net Leverage Ratio (“NLR”) would not exceed 3.50. The NLR is calculated as the proportion of (a) Net debt (Borrowings and Lease liabilities minus 
Cash, bank balances and other short-term investments) to (b) EBITDA (“Earnings Before Interest, Tax, Depreciation and Amortization”); 
(ii) its Interest Coverage ratio (“ICR”) would not be less than 2.00.  The ICR is calculated as the proportion of (a) EBITDA to (b) interest expenses for the 
year. 
All of the financial ratios and limitations described above will no longer apply if (i) the ON have an Investment Grade Rating from at least two Rating 
Agencies and (ii) no event of default has occurred and is continuing.  
As of December 31, 2024, Vista Argentina has been in compliance with all the covenants of its ON.  
 
See Note 33 for information on subsequent borrowings events. 
 
On October 29, 2024, Vista Argentina increased the amount of the “Programa de Notas”, approved by CNV for a total 
principal up to 3,000,000 or its equivalent in other currencies.

18.3  Warrants 
 
Along with the issuance of Series A ordinary shares in the Initial Public Offering (“IPO”), the Company placed 65,000,000 
warrants to purchase a third of Series A ordinary shares at an exercise price of 11.50 USD/share (the "Series A warrants."). 
Under those terms they expired on April 4, 2023, or earlier if after the exercise option the closing price of a Series A share is 
equal to or higher than the price equal to USD 18.00 during 20 trading days within a 30-day trading, and the Company opts for 
the early termination of the exercise term. Should the Company opt for the early termination, it will be entitled to declare that 
Series A warrants will be exercised "with no payment in cash.” Should the Company opt for the exercise with no payment in 
cash, the holders of Series A warrants that choose to exercise the option should deliver and receive a variable number of Series 
A shares resulting from the formula established in the deed of issue of warrants that captures the average of the equivalent in 
USD of the closing price of Series A shares during a 10-day period. 
 
Almost at the same time, the Company’s promoters purchased 29,680,000 warrants to purchase a third of Series A ordinary 
shares at an exercise price of 11.50 USD/share (the "warrants") for 14,840 in a private placement made at the same time as the 
IPO closing in Mexico. Warrants are identical and fungible with Series A warrants; however, the former could have differences 
regarding the early termination and may be exercised for cash or no cash for a variable number of Series A shares at the 
discretion of the Company’s promoters or authorized assignees. If warrants are held by other persons, then they will be 
exercised on the same basis as the other securities. 
 
The warrants exercise period began on August 15, 2018.  
 
On February 13, 2019, the Company completed the sale of 5,000,000 warrants for the purchase of a third of Series A ordinary 
shares in agreement with the forward purchase agreement and certain subscription commitment at an exercise price of 11.50 
USD/share (the “warrants”). 
 
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 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” (Note 18.5.1 and 21.1).

18.5 Fair value 
 
This note includes information on the Company’s method for assessing the fair value of its financial assets and liabilities. 
 
18.5.1 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 measured at fair value as of December 31, 2024 and 2023:

The value of financial instruments traded in active markets is based on quoted market prices as of the date of these 
accompanying 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 December 31, 2024. 
As of December 31, 2022, 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. 
The Company settled the financial liabilities for warrants as of December 31, 2022.

18.6 Risk management objectives and policies concerning financial instruments 
 
18.6.1 Financial risk factors  
 
The Company’s activities are exposed to several financial risks: market risk (including exchange rate risk, price risk and interest 
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 year-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.  This section includes a description of the main risks and uncertainties, which may adversely affect the Company’s 
strategy, performance, operational results and financial position. 
 
18.6.1.1 Market risk 
 
(i) 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, 2024 and 2023, the Company performed foreign exchange currency transactions and the impact in the results 
of the year is recognized in the consolidated statement of profit or loss in “Other financial income (expense)”. 
 
Most Company revenues 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 consolidated financial statements as of December 31, 2024 and 2023, and for the years ended December 
31, 2024, 2023 and 2022  
(Amounts expressed in thousands of US Dollars, except otherwise indicated) 
 
F-64 
During the years ended December 31, 2024, and 2023, ARS depreciated by about 28% and 356%, 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.

Inflation in Argentina 
 
As of December 31, 2024, and 2023, the 3 year cumulative inflation rate stood at about 1,219%, and 814%, respectively. 
 
For the years ended December 31, 2024 and 2023, the inflation rate was 117.8% and 211.4%, respectively. 
 
(ii) Price risk  
 
The Company’s investments in financial assets classified “at fair value through profit or loss” are sensitive to the risk of changes 
in market prices derived from uncertainties on the future value of these financial assets. 
 
The Company estimates that provided that the remainder variables remain constant, a revaluation (devaluation) of each market 
price detailed below will give rise to the following increase (decrease) in profit (loss) for the year before taxes in relation to 
the financial assets at fair value through profit or loss detailed in Note 18.5 to the consolidated financial statements:

Effect on profit before income tax 
11,537 / (11,537) 
15,243 / (15,243) 
 
(iii) Interest rate risk  
 
The purpose of interest rate risk management is to minimize finance costs and limit the Company’s exposure to interest rate 
increases. 
 
For the years ended December 31, 2024, 2023 and 2022 the average interest rate for borrowings in ARS was 41.98%, 3.37% 
and 41.42%, respectively.  
 
Variable-rate indebtedness exposes the Company’s cash flows to interest rate risk due to 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, 2024, and 2023, about 2% and 4% of indebtedness was subject to variable interest 
rates, respectively. 
 
For the years ended December 31, 2024, 2023 and 2022 the variable interest rate of borrowings denominated in USD stood at 
7.42%, 9.32% and 4.55% respectively.  
 
For the year ended December 31, 2022, the variable rate of borrowings denominated in ARS stood at 36.31%. 
 

VISTA ENERGY, S.A.B. DE C.V.  
Notes to the consolidated financial statements as of December 31, 2024 and 2023, and for the years ended December 
31, 2024, 2023 and 2022  
(Amounts expressed in thousands of US Dollars, except otherwise indicated) 
 
F-65 
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. 
 
The Company considers that the risk of an increase in interest rates is low; therefore, it does not expect substantial debt risk. 
 
For the years ended December 31, 2024 and 2023, the Company did not use derivative financial instruments to mitigate interest 
rate risks. 
 
18.6.1.2 Credit risk  
 
The Company establishes credit limits according to Management definitions based on internal or external ratings. It performs 
ongoing credit assessments on the customers’ financial capacity, which minimizes the potential risk of doubtful accounts. The 
customer’s credit risk is managed according to the Company’s procedures and controls. Pending accounts receivable are 
monitored on a regular basis.  
 
Credit risk represents the exposure to potential losses from customer noncompliance with the obligations assumed. This risk is 
mainly derived from economic and financial factors. 
 
The Company established a reserve for expected credit losses that represents the best estimate of potential losses related to 
trade and other receivables. 
 
The Company has the following credit risk concentration with respect to its interest in all receivables as of December 31, 2024, 
and 2023, and revenue per year.

The credit risk of mutual funds and other financial investments is limited since the counterparties are banks with high credit 
ratings. If there are no independent risk ratings, the risk control area assesses the customer’s solvency based on prior 
experiences and other factors. 
 
18.6.1.3 Liquidity risk  
 
Liquidity risk is related to the Company’s capacity to finance its commitments and carry out its business plans with stable 
financial sources, indebtedness level and the maturity profile of the financial payable. The Company’s Finance department 
makes cash flow projections. 
 
The Company supervises the updated projections on liquidity requirements to ensure the sufficiency of cash and liquid financial 
instruments to meet operating needs. These projections consider the plans to finance if applicable, external regulatory or legal 
requirements, such as, for example, restrictions in the use of foreign currency. 
 
Excess cash flow and the amounts above the working capital requirement are managed by the Finance department that mainly 
invests the surplus in mutual funds and money market funds by choosing instruments with timely due dates and currencies and 
proper credit quality and liquidity to provide sufficient margin according to the aforementioned projections. 
 
The Company diversifies its sources of funding between banks and capital markets and is exposed to refinancing risk upon 
expiry. 
 
Below is the assessment of the Company’s liquidity risk as of December 31, 2024, and 2023:

Access to the foreign exchange market in Argentina 
  
Below is the regulatory framework established by the Central Bank of Argentina (“BCRA” by Spanish acronym) during the 
years ended December 31, 2024 and 2023, whereby it introduced certain restrictions and adjustments on hoarding and 
consumption of currencies other than the ARS, and for the acquisition of currency that may be accessed by the Company: 
 
(i) Communiqué “A” 7552, as supplemented 
 
On July 21, 2022, through Communiqué “A” 7552, the BCRA set a maximum holding of 100,000 Argentine certificates of 
deposit (“CEDEAR” by Spanish Acronym) for parties accessing the official foreign exchange market. Through several BCRA 
communiqués the latest of February 10, 2025 (Communiqué “A” 8191) the following provisions are kept effective.   
 
The entity should have a sworn statement specifying, among others, the natural or artificial persons that exert direct control; 
and the evidence of the day in which market access is requested, showing that in the previous 90 calendar days (a) no securities

(ii) Communiqué “A” 8137, as supplemented 
 
On November 28, 2024, through Communiqué “A” 8137, the BCRA extended to 20 business days the term to enter into the 
exchange market and convert foreign currency from the collections of exports of goods and services; the proceeds from the 
sale of non-produced non-financial assets, and the reimbursements for the payments of imports made on the foreign exchange 
market, among others. 
 
Also, the term for the collection of goods exported is governed by points 7.1.1.1.to 7.1.1.5, Foreign Transactions and Exchange, 
as revised; i.e., the maximum term set regardless of the date of collection or additional withholding. 
 
The BCRA also established that the prepayments and pre- and post-financing from abroad should be entered into the foreign 
exchange market within 20 business days as from the date of collection or disbursement abroad. For exports falling under the 
scope of Presidential Decree No. 28/23, the previous is considered met when the exporter has entered into Argentina and 
converted into Argentine pesos on the foreign exchange market an amount not less than 80% of the countervalue of the 
prepayments, pre- and post-financing, and for the portion not settled, has acquired securities in foreign currency and sold them 
in Argentine pesos in Argentina.  
 
(iii) Communiqué "A" 8035, as supplemented 
 
On June 3, 2024, through Communiqué "A" 8035, the BCRA amends Communiqué “A” 7914 issued on December 7, 2023, 
and: (a) introduces some amendments to Foreign Transactions and Exchange regulations regarding access to the foreign 
exchange market for processing payments for imports of goods, and (b) extends the validity of the restrictions to access the 
foreign exchange market for certain financial payables through December 31, 2024. 
 
(iv) Communiqué “A” 8191, as supplemented 
 
On February 10, 2025, through Communiqué “A” 8191, the BCRA amended Communiqué “A” 8035 introducing substantial 
changes to access the foreign exchange market for the payment of imports of goods and services: 
 
- 
The statement is not required to have “SALIDA” status in Argentina’s system for imports (“SIRA” by Spanish Acronym) 
to access the foreign exchange market.  
 
- 
Entities may access the foreign exchange market without the BCRA’s prior approval to make deferred payments for imports 
of goods with customs entry registration in compliance with the regulation. 
 
Therefore, in the case of (a) petroleum oil or bituminous minerals, its related preparations and residues; (b) petroleum gases 
and other gaseous hydrocarbons; (c) not agglomerated bituminous coal; (d) electric power; (e) cleared imports of natural and 
enriched uranium and its compounds, heavy water or zirconium to be used in manufacturing energy or fuels, the entity may 
access the foreign exchange market without the BCRA’s prior approval.  
 
(v) Communiqué "A" 8118 
 
On October 21, 2024, Communiqué "A" 8118 established that the foreign exchange market to make deferred payments for 
imports cleared as from that date may be accessed after 30 calendar days from customs entry registration of the goods.  
 
(vi) Communiqué "A" 8133 
 
On November 21, 2024, BCRA Communiqué "A" 8133 set forth that importers may pay suppliers with own funds deposited 
in their local bank accounts or proceeds from their sales in foreign currency within 30 days the minimum term under 
Communiqué “A” 8118.  
 
Capital goods may be paid in advance provided that own funds deposited in local bank accounts in foreign currency are used. 
The related documentation should be provided in the case of remaining goods. This benefit applies to goods cleared in customs 
as from December 13, 2024.   
 
 

VISTA ENERGY, S.A.B. DE C.V.  
Notes to the consolidated financial statements as of December 31, 2024 and 2023, and for the years ended December 
31, 2024, 2023 and 2022  
(Amounts expressed in thousands of US Dollars, except otherwise indicated) 
 
F-69 
(vii) Communiqué “A” 7925, as supplemented 
 
BCRA Communiqué “A” 7925 of December 22, 2023, set the requirements for importers with outstanding payments abroad 
for the imports of goods or services cleared through December 12, 2023, to be able to subscribe Bonds for the Reconstruction 
for Free Argentina (“BOPREAL” by Spanish Acronym). These requirements were added to Communiqué “A” 8191. BCRA’s 
prior approval is required to access the foreign exchange market to pay payables for imports unless the transaction falls under 
any of the assumptions established therein. 
 
Importers of goods and services may subscribe BOPREAL up to the amount payable for their imports. They may sell these 
bonds in foreign currency in Argentina or abroad up to the amount acquired in the primary subscription, without limiting their 
access to the foreign exchange market.  
 
Also, Communiqué “A” 7935 set forth that as from April 1, 2024, subscribers of BOPREALs in primary biddings for payables 
for the import of goods and services may sell securities in foreign currency for the difference between the nominal value bid 
and the selling price on the secondary market obtained for the sale of BOPREALs.  
 
(viii) Communiqué “A” 8161, as supplemented 
 
On December 19, 2024, through Communiqué "A" 8161, the BCRA rendered void the BCRA’s prior approval required to 
access the clients’ foreign exchange market to pay when due compensatory interest accrued as from January 1, 2025, over the 
remaining original value of financial payables to related parties abroad.  
 
It also clarified that interest due as of December 31 or punitive interest or other equivalent interest accrued as from January 1, 
2025, will still require prior approval. 
 
It also established that the rest of the provisions in points 3.3.3. and 3.5.6. concerning foreign exchange market access to settle 
principal and interest of trade and financial payables to creditors that are parties related to the resident debtor will remain 
effective as from January 1, 2025. 
 
As of December 31, 2024 and 2023, the Company implemented the necessary actions to comply with the aforementioned 
communiqués and continues to monitor new changes in the regulatory framework and the impact of settling payables in 
currencies other than the ARS.

1) Series A Shares 
 
- Reduction of capital stock 
 
On September 27, 2022, the Board of Directors Meeting approved the reduction of the variable portion of the Company’s 
capital stock of 39,530, for the absorption of accumulated losses as of August 31, 2022, shown on the Company’s 
nonconsolidated financial statements. On December 7, 2022, through Ordinary General Shareholders’ Meeting this transaction 
was ratified. This transaction did not require the cancellation of Series A shares as they have no nominal value. Likewise, this 
operation did not generate any tax effect in Mexico. 
 
On December 5, 2024, the Board of Directors Meeting approved the reduction of the variable portion of the Company’s capital 
stock of 19,965, for the absorption of accumulated losses as of October 31, 2024, shown on the Company’s nonconsolidated 
financial statements. This transaction did not require the cancellation of Series A shares as they have no nominal value. 
Likewise, this operation did not generate any tax effect in Mexico. 
 
- Cashless exercises of warrants  
 
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 (Note 18.3). As a result, a 
maximum of 3,215,483 shares will become outstanding once all Warrants are converted. Similarly, on March 2, 2023, the 
CNBV authorized the automatic exercise without cash payment, so on March 15, 2023, by virtue of this automatic exercise, 
all outstanding warrants were exercised. Therefore, as of the date of these consolidated financial statements, there are no 
outstanding warrants.  
 
Thus, as of December 31, 2022, and 2023, 2,038,643 and 1,176,811 Series A shares were issued, respectively. They have no 
nominal value and the resulting amount of this swap, which stands at 32,144, is disclosed in “Other equity instruments.” 
 
- Share repurchase 
 
During the years ended as of December 31, 2022 and 2024, the Company repurchased 3,234,163 and 2,081,198 Series A shares 
for a total amount of 29,304 and 99,846, which are held in treasury. This operation did not generate any tax effect in Mexico. 
 
For the years ended December 31, 2022, 2023 and 2024, the Company granted 972,121; 5,772,141 and 2,011,219 Series A 
shares related to the LTIP. 
 
As of December 31, 2024 and 2023, the Company’s variable capital stock amounts to 95,285,451 and 95,355,430 fully 
subscribed and paid Series A shares with no face value, respectively, each entitled to one vote.  
 
As of December 31, 2024 and 2023, the Company’s authorized capital includes 33,506,788 and 33,436,809 Series A ordinary 
shares, respectively held in Treasury. 
 
2) Series C 
 
The variable portion of capital stock is an unlimited amount according to the Company’s bylaws and laws applicable, whereas 
the fixed amount is divided into 2 Series C shares. 
 
On March 17, 2023, Vista concluded a transaction that resulted in the acquisition of 2 Series C outstanding shares according 
to the share buy-back program authorized by the Company’s shareholders. These Series C shares are in the Company’s

and liabilities for leases less cash, banks and short-term investments) by (ii) total equity.  
 
The leverage ratio as of December 31, 2024, and 2023, is as follows:

22.1 Provision for well plugging and abandonment  
 
According to applicable regulations in the countries where the Company (either directly or indirectly through its subsidiaries) 
conducts oil and gas exploration and production activities, it should carry costs related to well plugging and abandonment. As 
of December 31, 2024 and 2023, the Company has a trust to plug and abandon wells in Mexico; however, it did not grant any 
asset as security to settle these obligations in Argentina. 
 
The provision for well plugging and abandonment represents the present value of dismantling costs related to oil and gas 
properties expected to be incurred through the end of each concession, when oil and gas producing wells to cease operations. 
These provisions were created based on the operator’s or the Company’s internal estimates, as appropriate.  
 
Assumptions based on the current economic context were made, so the Company considers that it is a reasonable basis to 
estimate future liabilities. These estimates are reviewed periodically to consider substantial changes in assumptions. However, 
the actual costs of well plugging and abandonment will ultimately depend on future market prices for the plugging and 
abandonment works needed. Moreover, wells will probably be plugged and abandoned when plots of land cease to produce at 
economically feasible rates. They will also depend on Crude oil and Natural gas future prices, which are uncertain by nature. 
 
The discount rate used in calculating the provision as of December 31, 2024, ranges between 5.15% and 5.57% whereas it 
ranges between 4.40% and 11.09% as of December 31, 2023. 
 
The Company conducted a sensibility analysis related to the discount rate. The increase or decrease of such rate by 10% would 
have 10% impact on well plugging and abandonment. 
 
Below are the changes in the provision for well plugging and abandonment for the year:

from the Concessions involved in the transaction through the end of the Operating Period. However, the Company still owns 100% of such concessions (Note 
1.1).   
 
22.2 Provision for environmental remediation 
 
The Company performs environmental impact assessments for new projects and investments, and the environmental 
requirements and restrictions imposed on these new projects had no major adverse effects on the Company’s businesses to 
date. 
 
The Company conducted a sensibility analysis related to the discount rate. The increase or decrease of such rate by 10% would 
have no significant impact on the environmental remediation obligation.

22.3 Provision for contingencies 
 
The Company (directly or indirectly through its subsidiaries) is part of commercial, tax and labor litigations and claims arising 
from the ordinary course of business. Upon estimating the amounts and likelihood of occurrence, the Company considered its 
best estimate with the assistance of legal advisors.  
 
The assessment of the estimates may change in the future due to new developments or unknown events upon assessing the 
provision. Consequently, the adverse resolution of the proceedings and claims assessed could exceed the provision set. 
 
The Company’s total claims, and legal actions amount to 14 and 101, from which it has estimated a probable loss of 14 and 
101 as of December 31, 2024 and 2023, respectively.  
 
The Company, considering its legal counsel’s opinion, estimates that the provision amount is sufficient to cover potential 
contingencies. It has booked a provision or disclosed all claims or other issues in these consolidated financial statements, either 
individually or in the aggregate.

Note 23. Employee benefits 
 
The employee benefit plans originally applies to Company employees that meet certain conditions, such as, for example, having 
participated uninterruptedly in the defined benefit plan, and that, having joined the Company before May 31, 1995, they have 
the required number of years in service and are therefore eligible to a certain amount according to plan provisions.  
 
It is based on the last computable salary and the number of years worked after deducting the benefits from the Argentine 
pension system managed by the Federal Social Security Administration (“ANSES” by Spanish acronym).  
 
Upon retirement, these employees are entitled to a monthly payment at constant value that is updated every year-end by the 
Consumer Price Index (“IPC” by Spanish acronym) published by the Argentine Institute of Statistics and Census (“INDEC by 
Spanish acronym). If the variation exceeds 10% during a certain year, the payment will be adjusted temporarily once the

The plan is backed by assets deposited exclusively by the Company and with no employee contributions to the trust fund. Fund 
assets may be invested by the Company in monetary market instruments denominated in USD or certificates of deposit to 
preserve accumulated capital and obtain returns in line with a moderate risk profile. Funds are mainly invested in United States 
of America bonds, Treasury bonds and trade notes with quality ratings. 
 
The Bank of New York Mellon is the trustee, and Willis Towers Watson is the business agent. Should there be an excess (duly 
certified by an independent actuary) of funds to be used to settle the benefits granted under the plan, the Company will be 
entitled to use it, in which case the trustee should be notified.

The following sensitivity analysis shows the effect of a variation in the discount rate and salaries increase on the obligation 
amount. 
 
(i) 
Should the discount rate be 1% higher (lower), the defined benefit obligation would decrease by 1,321 (increase by 1,539) 
as of December 31, 2024. 
 
(ii) Should the expected salary rise increase (decrease) by 1%, the defined benefit obligation would go up by 7 (go down by 
5) as of December 31, 2024. 
 
(iii) Should the discount rate be 1% higher (lower), the defined benefit obligation would decrease by 888 (increase by 1,034) 
as of December 31, 2023. 
 
(iv) Should the expected salary rise increase (decrease) by 1%, the defined benefit obligation would go up by 9 (go down by 
9) as of December 31, 2023. 
 
This sensitivity analysis was determined based on reasonably possible changes in the related assumptions as of every reporting 
year-end based on a change in an assumption with the rest held constant. This is unlikely to occur in actual facts and the changes 
in some assumptions may be related. Therefore, the analysis may not be representative of the actual change in the defined 
benefit obligation.  
 
Moreover, upon filing the previous sensitivity analysis, the present value of the defined benefit obligation was calculated using 
the projected unit credit method as of every reporting year-end, which is the same as the method applied to calculate the defined 
benefit obligation liability recognized in the statement of financial position. 
 
The methods and types of assumptions used in preparing the sensitivity analysis did not change with respect to the previous 
year.

assumes all obligations and payables from applicable Concessions until the end of the Operating Period; however, the Company maintains 100% ownership. 
 
Other than mentioned above, due to the short-term nature of current trade and other payables, their carrying amount is deemed

28.1 Duplicar Plus Project - Oldelval 
 
On December 21, 2022, the Company, through its subsidiary Vista Argentina, was awarded a crude oil transportation capacity 
of 5,010 cubic meters per day (“m3/d”) under the project to extend the current line from Allen to Puerto Rosales implemented 
by Oldelval (transportation concession holder) for 50,000 m3/d. Thus, the Company undertook to make an initial upfront 
investment of 118,000 between 2023 and 2025; which may be increased according to the project requirement and will be 
recovered from the monthly service fee.  
 
As of December 31, 2024 and 2023, the Company made disbursements related to this commitment for a total amount of 121,813 
and 34,660, respectively recognized in “Trade and other receivables” under “Advance payments for transportation services” 
(Note 17).

On January 27, 2023, the Company was awarded a storage and dispatch capacity of 35,666 m3 and 5,944 m3/d, respectively, 
under the project to expand the Puerto Rosales marine terminal and pumping station in which Oiltanking Ebytem S.A. 
(“Oiltanking”) launched tenders for 300,000 m3 and 50,000 m3/d of storage and dispatching capacity, respectively. 
 
The Company undertook to make an upfront investment of 28,400 between 2023 and 2025, which will be later recovered from 
the monthly service fee as from 2026. 
 
As of December 31, 2024, the Company made disbursements related to this commitment, for an amount of 19,677 recognized 
in “Trade and other receivables” under “Advance payments for transportation services” (Note 17). 
 
28.3 “Vaca Muerta Norte” Pipeline Agreement 
 
On May 16, 2023, the Company through its subsidiary Vista Argentina, entered into an agreement with 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 Vaca Muerta Norte (“VMN”), assigns to the remainder 
parties an undivided interest of the rights and obligations over the Transportation Concession amounting to: (i) 3.5% in favour 
of Equinor; (ii) 13.3% to Shell, and (iii) 8% to Vista Argentina (the “Assignment”). 
 
This concession is located in the Province of Neuquén from “La Amarga Chica” area to “Puesto Hernández” area (the 
“Transportation Concession”), and will be used to transport the production of all oil and gas areas in which the Parties have, 
now or hereafter, a VMN 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 VMN 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 VMN, which establishes the terms and 
conditions to operate, maintain and use of the aforementioned.  
 
As of the date of these consolidated financial statements, VMN is operational, and this Assignment is pending approval by the 
Executive Power of the Province of Neuquén.

28.4 Asociación de Superficiarios de la Patagonia (“ASSUPA” by Spanish acronym)  
 
On July 1, 2004, Vista Argentina was notified of a claim filed against it. In August 2003, ASSUPA filed a lawsuit against 18 
companies operating exploitation concessions and exploration permits in the Neuquén basin. 
 
ASSUPA claims remediation for the environmental damages supposedly caused by hydrocarbon exploitation activities, the 
creation of an environment restoration fund, and the implementation of measures to prevent future environmental damages. 
The plaintiff called the meeting of the Argentine government, the Argentine Federal Council for the Environment (“COFEMA” 
by Spanish acronym), the Provinces of Buenos Aires, La Pampa, Neuquén, Río Negro and Mendoza, and the National 
Ombudsman.  The plaintiff requested, as a precautionary measure, that the accused parties refrain from conducting activities 
that harm the environment. Both the subpoena of the National Ombudsman and the preliminary request were rejected by the 
Argentine Supreme Court of Justice (“CSJN” by its Spanish acronym). Vista Argentina responded the claim by requesting its 
dismissal and opposing to the plaintiff’s request. 
 
On December 30, 2014, the CSNJ issued two interlocutory orders. The order related to the Company supported the claim of 
the Provinces of Neuquén and La Pampa and declared that all environmental damages related to local and provincial situations 
were outside the scope of its original jurisdiction and that only "interjurisdictional situations" (such as the Río Colorado basin) 
would fall under its jurisdiction. The CSNJ also rejected the precautionary measures and other related proceedings. Vista 
Argentina, considering the legal counsel’s opinion, concluded that it is unlikely that a cash outflow be required to settle this 
obligation. 
 
As of the date of issuance of these financial statements, before the case is opened for trial, the parties are answering the notices 
served regarding the prior exceptions and challenges against the evidence filed, which are pending resolution. 
 
28.5 Extension of (non-operated) conventional exploitation concessions and the associated transportation concessions 
 
On December 6, 2024, through Decree No. 491/2024, the Province of Río Negro approved in favor of Vista Argentina the 
extension of (non-operated) conventional exploitation concessions for 10 years in the areas:  
 
(i) Entre Lomas and 25 de Mayo - Medanito S.E. and the associated transportation concessions both cases due in 2036, and  
(ii)  de Jagüel de los Machos through 2035. 
 
Under the extension of the Concessions, the Company, through its subsidiary Vista Argentina, undertook to pay the Province 
of Río Negro: (i) 22,000 for the extension, and (ii) a contribution of 4,400 to support institutional development and 
strengthening.    
 
Under the terms of the agreement signed with Aconcagua for the transfer of conventional assets (Note 3.2.7), the Company 
retains the ownership of the Concessions and will pay the Province the aforementioned amounts. However, Aconcagua, as the 
operator, will reimburse Vista for the payments made in relation to these items.  
 
As of December 31, 2024, a total payment of 13,200 was made related to 50% of the commitments assumed. The amount owed 
is booked under “Trade and other payables” within the line “Payables to third parties” (Note 26). Also, the receivable from 
Aconcagua for the same item is booked in “Trade and other receivables” within the line “Receivables from third parties” (Note 
17).

Hydrocarbon areas are operated by granting exploration permits or exploitation concessions by the federal or provincial 
government based on the free availability of hydrocarbons produced. 
 
29.2 Oil and gas areas and interests in joint operations      
 
As of December 31, 2024, 2023 and 2022, the Company, through its subsidiaries, is the owner and part of the joint operations

On December 21, 2018, through Decree No. 2,357/18, the Province of Neuquén approved the division and conversion of the 
operating concession in Bajada del Palo; in two unconventional hydrocarbon operating concessions (“CENCH” by Spanish 
acronym) so-called Bajada del Palo Este and Bajada del Palo Oeste for 35 years, including the payment of 12% royalties for 
the new production of unconventional formations. This decree replaces the conventional operating concession initially granted 
and determines the term of the concessions until December 21, 2053. 
 
In turn, Vista Argentina paid the following items to the Province of Neuquén: (i) an exploitation bonus for 1,168; (ii) an 
infrastructure bonus for about 2,796; and (iii) 3,935 as corporate social responsibility. Vista Argentina also paid 1,102 as stamp 
tax and committed to a major reserve development and exploration plan in the area.

29.2.1.1 Farmout agreement I  
 
On June 28, 2021, Vista Argentina entered into a farmout agreement with Trafigura (“farmout agreement I”), whereby it 
undertook to develop, initially, 5 pads made up of 4 wells each in Bajada del Palo Oeste area. Moreover, Trafigura may hold 
interests in up to 2 additional pads under the same terms and conditions. As of the date of theses consolidated financial 
statement, all committed pads were put into production. 
 
By virtue of the farmout agreement, a joint venture was established and Trafigura was entitled to contractual rights for 20% of 
hydrocarbon output in the pads under the agreement and bear 20% of investment costs, as well as royalties, direct taxes, and 
remainder operating and midstream costs. 
 
As part of the farmout agreement, Trafigura agreed to pay to Vista Argentina 25,000 as follows: (i) a 5,000 down payment; 
and (ii) 4 payments of 5,000 for each pad, which should be paid upon commencement of hydrocarbon production in each pad 
included in the farmout agreement I. 
 
As of the date of these consolidated financial statements, VISTA and Trafigura signed an agreement whereby as of January 1, 
2025, the Company will have the rights to 100% of the production of the pads related to the agreement (Note 1.2.2). 
 
29.2.1.2 Farmout agreement II 
 
On October 11, 2022, Vista Argentina entered into a farmout agreement II with Trafigura, whereby it undertook to develop 3 
pads in Bajada del Palo Oeste area. Trafigura was entitled to contractual rights for 25% of hydrocarbon output in the pads

F-81 
As of the date of these consolidated financial statements, VISTA and Trafigura signed an agreement whereby as of January 1, 
2025, the Company will have the rights to 100% of the production of the pads related to the agreement (Note 1.2.2). 
 
29.2.2 Coirón Amargo Norte  
 
Originally, the Joint operating agreement (“JOA”) Coirón Amargo owned an area located in the Province of Neuquén made up 
of an operating concession ("Coirón Amargo Norte") and an evaluation lot ("Coirón Amargo Sur") due in 2036 and 2017, 
respectively. 
 
On July 11, 2016, the partners of UT Coirón Amargo signed agreements to assign their interests whereby the area was divided 
in 3 independent lots: Coirón Amargo Norte ("CAN"), Coirón Amargo Suroeste (“CASO”) which was assigned to Shell on 
April 1, 2021, and Coirón Amargo Sur Este (“CASE”).  
 
CAN was made up of APCO Oil & Gas S.A.U. (“APCO SAU”, currently Vista Argentina), Madalena Energy Argentina S.R.L. 
(“Madalena”) and Gas y Petróleo del Neuquén S.A. (“G&P”) with 55%, 35% and 10%, respectively. Vista Argentina is the 
operator as from the date and the concession expires in 2036. 
 
According to the Operating Committee’ minutes of December 28, 2017, the carry agreement was signed; thus, the contributions 
made and to be made will be recognized as higher assets or expenses, as the case may be, in terms of the amounts actually 
disbursed by them, regardless of contractual equity interests.  
 
As from that date and until June 2020, Vista Argentina recognized its 61.11% interest in this joint operation, which is made up 
of its 55% contractual equity interest plus the 6.11% incremental portion acquired from G&P.  
 
On July 7, 2020, due to the default in payment by partner Madalena and in agreement with Coirón Amargo Norte JOA, Vista 
Argentina, together with its partner G&P decided to remove Madalena from the agreement by subscribing addendum VIII to 
the venture agreement for the exploration and exploitation of CAN. 
 
Ministry of Energy and Natural Resources Resolution No. 71/20 approved addendum VIII to the venture agreement and Decree 
No. 1,292/2020 of November 6, 2020, ratified such approval retroactively. Consequently, the Company, through its subsidiary 
Vista Argentina, increased its interest in the aforementioned JOA from 55% to 84.62% for no consideration.  
 
As from that date, and maintaining the abovementioned carry system, the Company recognizes all its interests in this joint 
operation in its consolidated financial statements.  
 
29.2.3 Águila Mora 
 
On August 22, 2018, APCO SAU signed an assignment agreement (the “Águila Mora swap agreement”) whereby:  
 
(i) Vista Argentina assigned to O&G Development Ltd S.A (currently “Shell”) a 35% nonoperated working interest in CASO’s 
oil & gas properties; 
 
(ii) Shell assigned to Vista Argentina a 90% operated working interest in Águila Mora’s oil and gas properties, plus a 
contribution up to 10,000 to refurbish its existing water infrastructure to benefit Shell and Vista Argentina operations.  
 
Águila Mora swap agreement obtained the approvals from the Province of Neuquén on November 22, 2018. Therefore, as from 
that date, the Company acquired a 90% working interest in Águila Mora’s oil and gas properties, becoming the operator. 
 
Through Decree No. 2,597/19 granted by the Province of Neuquén whereby G&P was granted the unconventional operating 
concession of Águila Mora area for 35 years, expiring on November 29, 2054. 
 
Vista Argentina maintains for such area a carry agreement for the interest in G&P and includes all its interests in this joint 
operation in the consolidated financial statements.

Note 30. Tax regulations  
 
A- General 
 
30.1 International tax reform pillar two model rules (“the model”) 
 
On May 23, 2023, the IASB issued amendments to IAS 12 to apply the pillar two model rules published by the Organization 
for Economic Co-operation and Development (“OECD”), which establish that this model applies to multinational enterprises 
with revenue in excess of Euros 750 million in their consolidated financial statements, they must pay a global minimum tax of 
15%.  
 
The main IASB amendments are: 
 
(i) A mandatory temporary exception to the deferred taxes accounting from the jurisdictional implementation of pillar two 
income taxes and; 
 
(ii) Disclosure requirements for affected entities to help users of the financial information better understand an entity's exposure 
to pillar two income taxes arising from that legislation, particularly before its effective date.  
 
As of the date of these consolidated financial statements, the jurisdictions where the Company mainly operates—Argentina 
and Mexico—have not issued the requested regulations on this Model. However, the Group operates in other jurisdictions in 
which the rules related to the Model have already been published and are effective for the year beginning January 1, 2024.  
 
Consequently, the Group assessed the Model’s potential income tax exposure based on the reports prepared by each country 
and the financial information reported by the subsidiaries and concluded that no impact should be recognized in the 
consolidated financial statements as of December 31, 2024. 
 
The Group keeps track of the Model’s legislative changes and the regulations of the different countries to assess the potential 
impact that they may have on the Company’s consolidated cash flows, financial position, and profit or loss. 
 
B- Argentina 
 
30.2 Income tax 
 
General 
 
As established by Law 27,630 issued in 2021, the applicable income tax rate for the Company, through its subsidiaries, is 35%. 
 
On August 16, 2022, the AFIP 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 by the Company, through its subsidiary Vista 
Argentina, in 3 equal and consecutive installments equivalents to 8,300 and computed as payment towards income tax for the 
year ended as of December 31, 2022. 
 
On July 20, 2023, the AFIP (Administración Federal de Ingresos Públicos, currently denominated Agencia de Recaudación y 
Control Aduanero “ARCA” by Spanish Acronym) issued General Resolution No. 5,391/2023, which establishes a one-time 
payment towards current income tax for taxpayers whose taxable income as of December 31, 2022, before computing prior-
year net operating loss 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. As of December 31, 2023, the Company, 
through its subsidiary AFBN S.R.L., made payments towards income tax for 979.

Notes to the consolidated financial statements as of December 31, 2024 and 2023, and for the years ended December

(Amounts expressed in thousands of US Dollars, except otherwise indicated) 
 
F-85 
On December 4, 2023, the AFIP issued General Resolution No. 5,453/2023, which establishes a one-time payment towards 
current income tax, for taxpayers who extract hydrocarbons, manufacture oil refinery products, and generate thermal power 
whose taxable income as of December 31, 2022, before computing prior-year net operating loss, 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.  
 
As of December 31, 2024 and 2023, the Company, through its subsidiary Vista Argentina, made payments towards income tax 
for 2,974 and 3,031, respectively.  
 
Dividends 
 
Law No. 27,541 on “Social Solidarity and Production Reactivation in the Context of a Public Emergency”, enacted through 
Presidential Decree No. 58/2019 suspended the increase in the established a rate by Law No. 27,430 set of 7% rates for the 
years beginning on or after January 1, 2021, currently in place. 
 
Tax Inflation Adjustment 
 
Law No. 27,468, issued in the year 2018, established that a third of the positive or negative adjustment for inflation applicable 
to the 3 first fiscal years beginning January 1, 2019, be distributed to the year in which the adjustment was determined and the 
remaining 2 thirds to the two subsequent tax periods.  
 
However, the Law No. 27,541, issued in the year 2019, amended this distribution and established that a sixth of the positive or 
negative adjustment for the first and second year beginning January 1, 2019, be charged to the year in which the adjustment is 
determined and the remainder 5 sixths, in equal parts, to the 5 subsequent tax periods, whereas for years beginning January 1, 
2021, 100% of the adjustment may be impute in the year in which it is determined. 
 
On December 1, 2022, was published in the Official Bulletin Law No. 27,701, set forth the option to defer the tax adjustment 
for inflation for the first 2 fiscal years beginning as from January 1, 2022. Thus, a third of such adjustment may be distributed 
to the fiscal year in which the adjustment is assessed and the remaining 2 thirds, in equal parts, to the two subsequent fiscal 
years. 
 
This alternative only 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.  
 
For the year ended December 31, 2023, the Company, through its subsidiary Vista Argentina, applied the option mentioned 
above. 
 
For the year ended December 31, 2024, and despite the disparity in the evolution of the IPC and the exchange rate throughout 
the period (Note 18.6.1.1), the Argentine Government did not establish a deferral mechanism for tax inflation adjustment, 
resulting in a significant increase in the income tax base. 
 
30.3 Tax for an inclusive and solidary Argentina (“PAIS Tax”) 
 
Law No. 27,541 issued in the year 2019, introduced a tax that is levied on the acquisition of foreign currency for 5 tax years at 
a 30% rate. This tax may not be used as payment towards any other tax and is levied on the following cases: (i) purchase of 
bills and foreign currency for hoarding purposes; (ii) change in currency to pay the acquisitions of assets or services and 
contracts for works made abroad irrespective of the method of payment used; (iii) acquisition of services abroad purchased 
from travel and tourism agencies in Argentina; or (iv) acquisition of passenger transportation services to be used abroad.  
 
On July 24, 2023, through Decree No. 377/2023, the PEN 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.  
On December 13, 2023, through Decree No. 29/2023, the PEN increased the rates under PAIS tax applicable to the acquisition 
of foreign currency for the payment of imports of goods and freight to 17.50%.

C- Mexico 
 
30.4 Income tax  
 
On October 31, 2019, the Mexican government approved the tax reform. This reform includes the following:  
 
(i) 
It limited the deductibility of net interest for the year, equal to the amount resulting from multiplying the taxpayer’s 
adjusted taxable profit by 30%. There is an exception with a cap of 20 million Mexican pesos for deductible interest at the 
group level in Mexico.  
 
(ii) It amended the Mexican Tax Code (“CFF” by Spanish acronym) to add new circumstances by virtue of which partners, 
shareholders, directors, managers or any other person in charge of a company’s management are considered joint and severally 
liable.  
 
(iii) the requirement to disclose “reportable schemes” by tax advisors or taxpayers. These schemes are defined as those that 
generate, or may generate, a tax benefit and include restructurings, transmission of NOLs, transfer of depreciated assets that 
may also be depreciated by the acquirer, the use of NOLs about to become statute-barred and abuse in the application of tax 
treaties with foreign residents, among others. 
 
(iv) the considered an organized crime with the related criminal penalties.  
 
The aforementioned reform is effective for fiscal years beginning on or after January 1, 2020. 
 
The Company’s Management concluded that this reform had no major effects on the consolidated financial information as of 
December 31, 2024, 2023 and 2022.  
 
Note 31. Share-based payments  
 
On March 22, 2018, the Company’s shareholders authorized that the LTIP be implemented to retain key personnel. Thus, the 
Board was empowered to manage the plan through an administrative trust. To such end, it set up a reserve of 8,750,000 Series 
A shares to be used in the plan; effective as from April 4, 2018. 
 
The plan has the following benefits paid to certain executives and employees that are considered share-based payments:

vested as follows: (i) 33% during the first year; (ii) 33% during the second year, and (iii) 34% during the third year in relation 
to the date in which stock options are granted to participants. Once acquired, stock options may be exercised up to 5 or 10 years 
as from grant date. The plan establishes that the value of the shares to be granted will be determined using Black & Scholes

Estimated Crude oil and Natural gas reserves  
 
Proved reserves as of December 31, 2024 and 2023, are net reserves attributable to Vista certificated by DeGolyer and 
MacNaughton for the assets located in Argentina, and Mexico. 
 
Proved Crude oil and Natural gas reserves are the quantities of Crude oil and Natural gas which, by analysis of geoscience and 
engineering data, can be estimated with reasonable certainty to be economically producible, from a given date forward, from 
known reservoirs, and under existing economic conditions, operating methods, and government regulations prior to the time at 
which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless 
of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must 
have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time. In 
some cases, substantial investments may be required in related wells and facilities to recover proved reserves. 
 
The Company considers that its remaining estimated volumes of Crude oil and Natural gas proved recoverable reserves are fair 
and that these estimates were prepared according to SEC regulations and ASC 932, as amended. Consequently, Crude oil prices 
used in determining proved reserves were the average price during the 12 months prior to the end date of December 31, 2024, 
and 2023, respectively, determined as an unweighted average of the first day of the month for each month within these periods. 
Moreover, since there are no Natural gas prices available in the benchmark market in Argentina, VISTA used the average 
Natural gas prices for the year to determine Natural gas reserves. In addition, for certain Natural gas volumes, Vista will obtain 
an incentive price subsidized by the Argentine government through “Gas Plan IV”. A weighted average price is estimated for 
certain areas per subsidized and unsubsidized volume. 
 
The independent certificators carried out by DeGolyer and MacNaughton as of December 31, 2024 and 2023 in Argentina and 
Mexico, covered all the estimated reserves located in the areas operated and not operated by the Company. 
 
In all cases, were audit the estimated reserves according to Rule 4-10 of Regulation S-X issued by the SEC, and according to 
the provisions for disclosing Crude oil and Natural gas reserves under FASB ASC 932. We provided all the information 
requested during the audit processes. In Argentina royalties paid to the provinces have not been deducted from reported proved 
reserves. Gas includes gas sale and consumption. 
 
The volumes of liquid hydrocarbons represent Crude oil, condensate, gasoline and LPG to be recovered in field separation and 
plant processing and are reported in million barrels (“MMBbl”) The volumes of Natural gas represent expected gas sales and 
the use of fuel in the field and are reported in billion cubic feet (“Bcf”) (109) in standard conditions of 14.7 psia and 60°F. Gas 
volumes arise from the separation and processing in the field, which are reduced by injection, venting and shrinkage, and 
include the volume of Natural gas consumed in the field for production. Natural gas reserves were converted into liquid 
equivalent using the conversion factor of 5.615 cubic feet of Natural gas per 1 barrel of liquid equivalent. 
 
The following tables show proved oil reserves, net (including Crude oil, condensate oil and LPG) and Natural gas reserves, 
net, as of December 31, 2024, 2023, 2022 and 2021 according to VISTA’s interest percentage in the related concessions:

Este (-0.96 MMbbl); (iv) Bajada del Palo Oeste (-0.60 MMbbl); (v) Bajada del Palo Oeste (Farmout Agreement I and II) (-0.66 MMbbl and -0.42 MMbbl) 
respectively; (vi) other fields (-0.24 MMbbl); (vii) positive results in Bajada del Palo Este (+3.02 MMbbl); Bajada del Palo Oeste (+1.63 MMbbl); and (viii) 
combined effect of other fields (+0.59 MMbbl). 
 
(b) in connection with the undeveloped reserve: (i) changes in the development plan in Bajada del Palo Este (-0.11 MMbbl); and (ii) the combined effect of 
other fields (-0.17 MMbbl). 
 
The changes from prior-estimate revisions of proved developed and undeveloped Natural gas reserves (-5.2 Bcf) are mainly related to:  
 
(a) in connection with the developed reserve: (i) decreased activity in Bajada del Palo Este (-3.59 Bcf); (ii) lower performance and adjustment of the gas/oil 
ratio (“GOR”) in the wells of Bajada del Palo Oeste (-8.49 Bcf); and (iii) effect of other fields (-1.43 MMbbl). The positive results are related to wells in 
Aguada Federal (+0.73 Bcf); Bajada del Palo Este (+2.07 Bcf); Baja del Palo Oeste (+1.91 Bcf); Entre Lomas in Rio Negro Province (+3.42 Bcf) and combined 
effect of other fields (+2.57 Bcf).

wells) incorporating (+2.68 MMbbl y +2.25 Bcf); (ii) Bajada del Palo Este with a 2 pad (8 wells) (+6.80 MMbbl y +3.52 Bcf); (iii) a 4 pad (13 wells) in Bajada 
del Palo Oeste incorporating (+15.98 MMbbl y +14.66 Bcf).  
 
Also, there is a neutral effect from the conversion of proved undeveloped reserves to proved developed reserves generated by: (i) the drilling success in Vaca 
Muerta formation of 5 pads (21 wells) in Bajada del Palo Oeste adding (+24.99 MMbbl y +23.36 Bcf); (ii) the addition of 2 pads (5 wells) in Bajada del Palo 
Este incorporating (+5.61 MMbbl y +2.82 Bcf); as well as (iii) the recategorizations in Bajada del Palo Oeste (Farmout Agreement I and II)  adding (+0.32 
MMbbl y +0.29 Bcf ). 
 
(b) in connection with the undeveloped reserve enable by the activity of drilling in Vaca Muerta formation of: (i) Aguada Federal adding (+4.11 MMbbl y 
+3.48 Bcf), Bajada del Palo Este totaling (+24.29 MMbbl y +12.55 Bcf), and Bajada del Palo Oeste, totaling (+19.64 MMbbl y +12.72 Bcf).

(a) in connection with the developed reserve: (i) The lower performance and price decrease (-0.4 Bcf); and (ii) due to the extension of (+3.3 Bcf) from the 
successful drilling of two new Vernet-1051 and 1052 blocks. 
 
(b) in connection with the undeveloped reserve: (i) an increase of (+6.4 Bcf) because cash-paid royalties for reserves and production volumes are not 
discounted; and (ii) an increase due to the extension of acreage from the drilling campaign in the same blocks with Vernet-1053 and 1054 wells, resulting in 
an increase of (+0.7 Bcf). 
 
In addition, there is a neutral effect from the conversion of proved undeveloped reserves to proved developed reserves generated by: (i) the successful drilling 
campaign of Vernet-1001, 1002, 1004, 1005, and 1006 (+1.65 MMbbl and +1.67 Bcf).

Standardized measure of future discounted cash flow (net)  
 
The following table describes estimated future cash flows from the future production of proved developed and undeveloped 
reserves of Crude oil, condensate, LPG and Natural gas. As established by SEC Modernization of Oil and Gas Reporting rules 
and ASC 932 of the FASB Accounting Standards Codification (“ASC”) relating to Extractive Activities—Oil and Gas 
(formerly SFAS 69 Disclosures about Oil and Gas Producing Activities), these cash flows were estimated using the twelve-
month average of the first day-of-the-month benchmark prices as adjusted for location and quality differentials and using a 
10% annual discount factor. Future development and abandonment costs include estimated drilling costs, development and 
exploitation facilities and abandonment costs.  These future development costs were estimated based on VISTA assessments. 
Future income tax was calculated by applying the statutory tax rates effective in Argentina in each period. 
 
This standardized measure is not intended to be, and should not be, interpreted as an estimate of the market value of the 
Company’s reserves. The purpose of this information is to provide standardized data to help the users of the financial statements 
to compare different companies and make certain projections. This information does not include, among others, the effect of 
future changes in price costs and tax rates, which past experience shows that they are likely to occur, and the effect of the future 
cash flows of reserves that have not been classified as proved reserves yet, of a discount factor that best represents the value of 
money over time and of the risks inherent in Crude oil and Natural gas production. These future changes may have a major 
impact on future net cash flows disclosed below. Therefore, this information does not necessarily show the Company’s 
perception on future discounted cash flow, net, of the hydrocarbon reserve.

TRANSLATION 
 
EXTENSION AGREEMENT FOR THE EXPLOITATION CONCESSIONS 
OVER THE AREAS ENTRE LOMAS, 25 DE MAYO – MEDANITO S.E and 
JAGÜEL DE LOS MACHOS AND RELATED TRANSPORTATION 
CONCESSIONS 
 
In the city of Cipolletti, on November 29, 2024, the PROVINCE OF RÍO NEGRO, 
represented in this act by the State Secretary of Energy and Environment, ANDREA 
CONFINI, domiciled at Los Arrayanes and Los Sauces in the City of Cipolletti, in her 
capacity as ENFORCEMENT AUTHORITY of Law No. 17319, hereinafter referred to 
as the PROVINCE; and VISTA ENERGY ARGENTINA S.A.U., represented in this 
act by JUAN GAROBY in his capacity as attorney, domiciled at Hipólito Yrigoyen 558, 
City of Cipolletti, Río Negro, hereinafter referred to as the CONCESSIONAIRE, and 
jointly with the PROVINCE referred to as the PARTIES, agree to enter into this 
EXTENSION AGREEMENT for the Exploitation Concessions of the hydrocarbon areas: 
 
PRELIMINARY CONSIDERATIONS:  
VISTA ENERGY ARGENTINA S.A.U. is the holder of one hundred percent (100%) of 
the Exploitation Concessions over the hydrocarbon areas “ENTRE LOMAS”, “25 DE 
MAYO – MEDANITO SE” and “JAGÜEL DE LOS MACHOS”; and of the Gas 
Transportation Concession “ENTRE LOMAS”, and the Crude Oil Transportation 
Concessions “ENTRE LOMAS” and “25 DE MAYO – MEDANITO SE”.  
Under Provincial Law Q No. 4818, by Decree No. 1706/14, as ratified by Law No. 5027, 
the Renegotiation Agreement for the area “ENTRE LOMAS” was approved; at the date 
of execution of the Renegotiation Agreement, the holder was Petrolera Entre Lomas S.A. 
In 2018, Petrolera Entre Lomas S.A changed its corporate name into Vista Oil & Gas 
Argentina S.A, and subsequently, in 2022, to Vista Energy Argentina S.A.U. 
Also, under Provincial Law Q No. 4818, through Decree No. 1708/14 and ratified by Law 
No. 5027, the Renegotiation Agreement for the areas “JAGÜEL DE LOS MACHOS” 
and “25 DE MAYO – MEDANITO SE” was approved; at the date of execution of the 
Renegotiation Agreement, the holder was Petrobras Argentina S.A. After a merger 

process, Pampa Energía became the successor of Petrobras Energía S.A. Then, by Decree 
No. 806/19, the Provincial Executive Branch authorized the assignment of one hundred 
percent (100%) of the participating interest in the Exploitation Concessions “Jagüel de 
los Machos” and “25 de Mayo – Medanito SE” to Vista Oil & Gas Argentina S.A., later 
on called Vista Energy Argentina S.A.U. 
In addition, the Hydrocarbon Transportation Concessions on the oil pipelines and Related 
Plants Complex of the areas “25 de Mayo – Medanito SE” and “Entre Lomas”, and on 
the gas pipeline and its related Gas Treatment Plant of the area “Entre Lomas” were 
granted by Provincial Decrees No. 1821/19, 1822/19, and 1823/19 to Vista Oil & Gas 
Argentina S.A.U., later on called Vista Energy Argentina S.A.U.  
Under the powers mentioned in the previous paragraph, Vista Energy Argentina S.A.U. 
expressed its intention to extend the term of the Exploitation Concessions and of the 
related Transportation Concessions, making itself available to the Enforcement Authority 
with the purpose of setting the terms and conditions of the requested extensions. 
Through Law No. 5733, the Enforcement Authority initiated the EXTENSION process, 
thus requiring the CONCESSIONAIRE to file certain documentation and information on 
the Exploitation and Transportation Concessions applicable to the EXTENSION

ANNEX B – ENVIRONMENTAL REMEDIATION 
 
Under this ANNEX, environmental liabilities are classified according to their origin, as 
follows: 
Historical Liabilities: Those arising during the previous exploration and exploitation 
stages, which were not remediated at that time. These liabilities may be large-scale and 
complex, and they may represent a significant risk for both the environment and human 
health. 
Current Liabilities: Those arising during the current operation stage. 
Future Liabilities: Those that may arise during the abandonment stage of an oil field. 
These liabilities can be of various types, such as soil, groundwater or air contamination, 
the presence of out-of-service facilities, or loss of biodiversity. 
 
Section 1. HISTORICAL LIABILITIES. 
To determine the Historical Liabilities, the environmental Enforcement Authority will 
agree with the CONCESSIONAIRE on the inventory of existing liabilities and its 
prioritization for the relevant remediation, according to the sample spreadsheet attached 
hereto. 
Communications. Communications will always be carried out through letters, meeting 
minutes, and inspection and/or violation reports. Any partial release from liabilities will 
be made through a technical report from the Enforcement Authority. 
Final releases from liabilities will be made through an administrative act of the 
environmental Enforcement Authority. 
 
Section 2. CURRENT LIABILITIES. 
· From Incidents 
· Decommissioning of Facilities 
· Repositories for Waste Stockpiles (Hazardous and Household-like Waste) 
· Pits of any Kind 
Liabilities from Incidents will be fully managed through the INPRO system in compliance 
with all the rules issued by the environmental Enforcement Authority. 

 
The Decommissioning of Facilities will be the result of a facility abandonment process 
that may potentially generate hazardous waste under Law No. 3250; therefore, the process 
begins by submitting an abandonment report to the Secretary of Environment and Climate 
Change. 
The repositories for soils with hydrocarbons or stockpiles of waste defined as special by 
Law No. 3250 will be managed fully in accordance with the terms in that law. 
 
Section 3. FUTURE LIABILITIES. 
At the end of the concession period, there will be assets and liabilities on the surface under 
concession. 
Some environmental liabilities that may be found are, for instance: 
· Repositories (Hazardous and Household-like Waste) 
· Historical liabilities the remediation of which has not been completed may be included 
in this item. 
· Current Liabilities (resulting from the operation) that are in process or the treatment of 
which has not yet begun. 
· Plants and Facilities that have reached the end of their useful life. 
· Wells that must be abandoned. 
Six months before the end of the concession period an environmental audit of the area 
will be SUBMITTED to certify the environmental condition of such area; it will be 
performed by an external firm registered with the registry of environmental consultants 
and evaluated by the Secretary of Environment and Climate Change. If there are any 
remaining environmental liabilities, the CONCESSIONAIRE will present to the 
Secretary of Hydrocarbons a REMEDIATION PERFORMANCE BOND posted by the 
CONCESSIONAIRE to guarantee compliance of the obligations undertaken in the 
PREVIOUS sections, for an amount equal to the total cost of the identified liabilities. 
 
Section 4. ABANDONMENT OF WELLS. 
4.1 The CONCESSIONAIRE agrees to abandon all wells subject to Resolution 
No. 5/1996 of the Argentine Secretary of Energy and Resolution No. 339/SAYDS/2018 
of the Secretary of Environment and Climate Change of the Province as from the 
commencement of this EXTENSION AGREEMENT. 

 
4.2 Notwithstanding the dates scheduled for the final abandonment of wells contemplated 
in this EXTENSION AGREEMENT, the CONCESSIONAIRE agrees to: 
4.2.1 Permanently abandon any well the early final abandonment of which is advisable 
according to its priority level according to the criteria and scope stated in Annex I of 
Resolution No. 5/96 of the Argentine Secretary of Energy, and Resolution 
No. 339/SAyDS/2018 of the Secretary of Environment and Climate Change of the 
Province, and/or according to the environmental risk assessed together with the Secretary 
of Environment and Climate Change. 
4.2.2 Prior to converting a well into an injection well, nearby inactive wells that are at 
twice the spacing distance shall be examined to ensure their mechanical integrity through 
a hydraulic test and corrosion logging or applying another accepted technique in order to 
guarantee that there is no leak risk in the injection grid and/or any impact on aquifers. 
Should any anomaly be identified in such wells, they will be repaired and/or abandoned 
before starting any injection, according to the applicable legal rules. The parties agree 
that the results from this analysis will be submitted to the ENFORCEMENT 
AUTHORITY prior to conducting the targeted conversion.

ZERO POINT ONE PER CENT (0.1%) at the transfer point of the exploration permit or 
exploitation concession to the transportation concession, refinery or land transportation 
system.” 
9.9.2. If the CONCESSIONAIRE lacks financial resources or operative possibilities to 
comply with this requirement, it shall submit a written request with a proper explanation, 
and it will be at the discretion of the ENFORCEMENT AUTHORITY to grant permission 
to carry out an alternative production measurement. 
9.9.3. The Points and/or Facilities contemplated in Resolution No. 557/2022 or 
Resolution No. 318/2012, as applicable, must be registered in the “REGISTRATION

AUTHORITY requires the performance of an exceptional audit. 
9.9.6. An inspector of the Secretary of Hydrocarbons shall be present at all inspections or 
when maintenance, calibration, and verification tasks are performed, and notice of those 
inspections and tasks must be given at least 10 days in advance. 
9.9.7. In the case of Measurement Points, instruments, equipment and all their 
components that have not been inspected, maintained, calibrated and verified as 
established by Resolution No. 557/2022, they will be scheduled for inspection, 
maintenance, calibration and verification, to be performed within the first 6 months of 
effectiveness of this AGREEMENT. 

 
9.9.8. Audits resulting from inspections conducted on the equipment must be submitted 
to the ENFORCEMENT AUTHORITY. Such audits will be deemed completed when all 
the adaptations recommended by them have been performed and accepted through a 
subsequent audit to be conducted within the next 6 months. If the CONCESSIONAIRE 
is unable to make the adjustments within 6 months, it shall send a letter duly explaining 
the reasons for that failure and offering an alternative, subject to approval by the 
ENFORCEMENT AUTHORITY. 
9.9.9. The CONCESSIONAIRE shall certify the metering point, where the production is 
to be released from the exploitation concession area, as provided for in Resolution 
No. 557/2022, within the first 12 months of effectiveness of this AGREEMENT. If the 
CONCESSIONAIRE is unable to certify its Measurement Points, it shall send a letter 
duly explaining the reasons for that failure, subject to approval by the ENFORCEMENT 
AUTHORITY. 
9.10. GAS RECOVERY AND UTILIZATION. 
When batteries and plants located within the provincial territory must process light crude 
oils with high vapor pressure, i.e., with a high degree of evaporation, all their equipment 
must be connected to a gas recovery system through their vent ports, relief valves, and 
elements related to process control or safety. 
When the low gas-to-oil ratio does not justify the economic and operational feasibility of 
using the gas produced, and this ratio falls below the values established in Article 5 of 
Law Q No. 2175, the gas may be directed to flaring through properly designed venting 
systems. 
In the case of heavy or intermediate crude oils with a low amount of gas in solution, the 
breathing gas recovery system of the equipment related to the processes shall be equipped 
with elements the discharges of which will be connected to a vent stack to be flared. 
9.10.1. The CONCESSIONAIRE shall develop an action plan improving the plant and 
battery processes of all the concession area in order to recover gases safely and efficiently, 
burning them if it is not advisable to properly utilize such gases and preventing them from 
being freely released to the atmosphere. 
Such project shall be implemented after the fifth effective year of this Extension, starting 
by those plants that process higher flows of gas and/or that operate lighter crude oils. 

 
9.10.2 Jointly with the ENFORCEMENT AUTHORITY, a plan must be developed to 
capture gases unintentionally emitted into the atmosphere, classified as fugitive 
emissions, originating from pressurized equipment, tanks, compressors, relief valves, 
safety valves, pressure and vacuum valves, flame arresters, etc., which must be connected 
to gas venting systems to be properly burned through venting flares or pits. Additionally, 
an appropriate strategy must be planned to capture fugitive emissions and progressively 
reduce their release. 
9.11. SAFETY VALVES. 
The safety valves in all facilities shall undergo calibration at least annually when they 
work with sweet gas and every 6 months if they work with gas containing sulfur. 
9.12. TRANSPORTATION CONCESSIONS. 
The provisions in Law Q No. 5594 shall be observed. 
9.13. RECOVERY CHAMBERS. 
Within the first 6 months of effectiveness of this AGREEMENT, 
the 
CONCESSIONAIRE shall submit to the ENFORCEMENT AUTHORITY a report with 
the integrity assessments of all the liquid recovery chambers and the tightness assessment 
of those chambers. All those chambers which are not tight enough shall be removed from 
operation immediately, and all necessary measures shall be taken so that the related 
facility may continue operating as usual. The relevant chamber shall be repaired to be 
used again under the express authorization of the ENFORCEMENT AUTHORITY. 
9.14. CELLARS. 
Within the first 6 months of effectiveness of this AGREEMENT, 
the 
CONCESSIONAIRE shall submit to the ENFORCEMENT AUTHORITY a program on 
a well-by-well basis stating the frequency for purging and cleaning the well cellars. 
9.15. ROADS. 
A road maintenance and optimization program shall be submitted quarterly. 
9.16. EMERGENCY PITS. 
All emergency pits must be empty and clean during normal operations. They must also 
be prepared to prevent contingencies, and they may not be used for standard procedures, 
but only for unforeseen events inherent to the operation or contingencies. The facilities 
must have pits according to the most rational, modern and/or efficient techniques that the 

 
Secretary of Environment and Climate Change of the Province and/or the authority 
replacing it may approve according to the current laws. 
9.17. HYDROCARBONS AND BY-PRODUCTS FROM OTHER PROVINCES. 
The CONCESSIONAIRE and/or the OPERATOR shall report any receipt of 
hydrocarbons and by-products coming from other concession areas or provinces. The 
relevant Fluid Reception Operating Procedure shall be submitted to the 
ENFORCEMENT AUTHORITY for evaluation. In addition, the receipt of produced 
water, hazardous waste, slop, and any product or by-product intended for treatment or 
final disposal within the territory of Río Negro must be reported. 
9.18. VENT EXEMPTION REQUEST. 
Vent exemption requests must be made in writing to the ENFORCEMENT 
AUTHORITY at least 10 running days in advance. 
Any accidental gas venting resulting from plant or equipment failure, such as treatment 
or compression equipment, are deemed contaminating incidents and, thus, the companies 
operating such plants or equipment shall comply with the provisions in Resolution SEN 
No. 143/1998. In the case of the PROVINCE OF RÍO NEGRO, the provisions in Decree 
No. 656/2004 and Resolution No. 2/2012 are applicable; thus, those environmental 
incidents must be reported in the INPRO system. 
Each scheduled exemption, whichever the venting term required by the operation may be, 
must be requested through a specific submission stating in each case the cause for the 
exemption that may eventually apply and the estimated maximum gas flow to be vented, 
as and when set forth in Resolution No. 143/1998. 
9.19. PIPELINES. 
Whenever there are repeated (multiple) ruptures of a pipeline or pipe within less than 10 
lineal meters and in a maximum of a 12-month period, the company shall carry out an 
integrity assessment to evaluate if it should be replaced or alternatively repaired, 
rehabilitated through coatings or new technologies. 
Submit that study to the ENFORCEMENT AUTHORITY with an explanation of the 
measures to be taken and stated dates of execution. 
With those results, the ENFORCEMENT AUTHORITY may intervene in the measures 
taken, request different adaptations, more information or other type of method to assess 
the pipeline integrity. 

 
The ENFORCEMENT AUTHORITY states that, if the CONCESSIONAIRE fails to 
comply timely and as appropriate, it will be subject to the violation report process stated 
in Section 4.7 of the EXTENSION AGREEMENT and the relevant sanctions may be 
imposed to it.

• Mexican Stock Market Law (Ley del Mercado de Valores or “LMV”); 
• The General Provisions Applicable to Issuers of Securities and other Stock Market 
Participants (Disposiciones de Carácter General Aplicables a las Emisoras de Valores y a 
otros Participantes del Mercado de Valores or “Securities Regulations”); and  
• The General Provisions Applicable to Transactions in Securities Conducted by Members of 
the Board of Directors, Officers and Employees of Financial Entities and Other Regulated 
Entities (Disposiciones de Carácter General Aplicables a las Operaciones con Valores que 
Realicen los Consejeros, Directivos y Empleados de Entidades Financieras y Demás 
Personas Obligadas),  
the Company has adopted the policies and procedures described in this document (the “Policy”). 
II.

by the spouse and minor children of a Company Person and by adult members of the household of a 
Company Person, and any entity that a Company Person directly or indirectly influences or controls

VI. 
Statement of Policy 
a. General Prohibition Against Insider Trading 
No Trading or Tipping on Privileged Information 
Any Company Person in possession of Privileged Information about the Company shall under no 
circumstance:  
(i) 
buy, sell or otherwise engage in any transactions, directly or indirectly, in any 
Company Securities, which listing or price may be influenced on the basis of such 
Privileged Information; 
(ii) 
make recommendations with respect to Company Securities, which listing or price 
may be influenced on the basis of such Privileged Information;  
(iii) 
disclose such Privileged Information to any third party, unless the respective transferee 
is required to access such Privileged Information due to its job, position or 
commission; or 
(iv) 
assist anyone in the above activities. 
The above restrictions also apply to transacting in the securities of another company while in 
possession of Privileged Information relating to such other company, when that information is 
obtained in the course of employment with, or other services performed on behalf of, the Company 
or any subsidiary of the Company. 

 
 
Unless otherwise provided for in this Policy and applicable law, transactions that may be necessary 
or justifiable for independent reasons are not excepted from these restrictions. The securities laws do 
not recognize mitigating circumstances. In any event, even the appearance of an improper transaction 
must be avoided to preserve the Company’s reputation for adhering to the highest standards of 
conduct. 
Privileged Information 
It is not possible to define all categories of material information, as the ultimate determination of 
materiality by enforcement authorities will be based on an assessment of all of the facts and 
circumstances. Information that is not material at one point in time may later become material, and 
vice versa. 
In general, information is considered “material” if there is a reasonable likelihood that it would be 
considered important to an investor in making a decision to buy, hold or sell securities. Any 
information, action or event, of any nature, that could be expected to influence a company’s 
securities’ price, whether positive or negative, and whether the change is large or small, constitute a 
material event (“Material Event”) and so long as such Material Event is not disclosed through the 
Mexican Stock Exchange and broadly to the marketplace (for example, included in a press release) 
constitutes “Privileged Information”. 
It may be difficult under this standard to determine whether particular information, actions or events 
should be considered Material Events, but there are certain categories that are particularly sensitive 
and, as a general rule, should always be considered Material Events. Examples of Material Events 
under the Securities Regulations include the following: 
(i) 
In connection with the corporate structure of the Company: 
(a) Changes in the corporate structure of the Company. 
(b) Changes in the members of the corporate bodies of the Company or of its Relevant 
Officers, as well as the reasons that may have motivated such changes. 
(c) Amendments to the Company’s by-laws. 
(ii) 
In connection with the businesses of the Company: 
(a) The negotiation or execution of material agreements not in the ordinary course of 
business or the amendment or termination thereof. 
(b) The execution, breach, resolution or termination of co-operation or joint venture 
agreements by the Company or the companies controlled by the Company or in 
which the Company has “Significant Influence” (understood as a position that 
grants he or she with voting rights of 20% or more over the respective company’s 
stock capital). 
(c) The execution, breach, resolution, amendment or termination of agreements with 
suppliers, clients or governmental agencies of any level, which are crucial for the 
fulfilment of the corporate purpose of the Company or the companies controlled 

 
 
by the Company or in which the Company has Significant Influence. 
(d) The participation in biddings or tenders by the Company or the companies 
controlled by the Company or in which the Company has Significant Influence, 
as well as the results thereof. 
(e) The gain or loss of a substantial customer or supplier by the Company or the 
companies controlled by the Company or in which the Company has Significant 
Influence. 
(f) The announcement, development, creation or cancellation of a business line, 
product or services by the Company or the companies controlled by the Company 
or in which the Company has Significant Influence, or any significant defects or 
modifications thereof. 
(g) The timing of a new product, service or technology. 
(h) Significant pricing changes. 
(i) Impending bankruptcy or financial liquidity problems of the Company or the 
companies controlled by the Company or in which the Company has Significant 
Influence. 
(j) Discovery of resources or the development, acquisition or application of new 
technology impacting the business of the Company or the companies controlled 
by the Company or in which the Company has Significant Influence. 
(k) Incorporation, separation, retirement or exclusion of partners or shareholders who 
have entered into agreements or who collaborate in the operation related to 
financial, legal, technological or administrative affairs of the Company or the 
companies controlled by the Company or in which the Company has Significant 
Influence. 
(l) News or negotiation of the disposition or acquisition of significant assets or a 
subsidiary. 
(m)Significant cybersecurity incidents. 
(iii) 
In connection with the Company Securities: 
(a) News, negotiation or execution of investment projects, mergers or acquisitions, or 
any project that involve the acquisition of shares of the Company which, as a 
result, modify its capital structure and, as the case may be, the capital structure of 
the companies controlled by the Company or in which the Company has 
Significant Influence. This paragraph shall also apply to development, real estate, 
energy and infrastructure, investment projects and exchange traded trust notes 
(certificados bursátiles fiduciarios de desarrollo, inmobiliarios, de inversion en 
energía e infraestructura, o de proyectos de inversion). 

 
 
(b) As the case may, any changes to the Company’s rating as determined by a rating 
agency. 
(c) The causes for the acquisition by the Company of the Company’s own shares in 
atypical or unusual volumes. 
(d) Any information, actions, facts or events related to public offerings of Company 
Securities. 
(e) The offering of Company Securities in national or foreign stock exchanges, as 
well as any decision to de-list such Company Securities. 
(f) Stock splits. 
(iv) 
In connection with the financial situation of the Company: 
(a) Financial results.  
(b) Deviations in the performance of the Company or the companies controlled by the 
Company or in which the Company has Significant Influence, with respect to the 
outlook or assumptions previously disclosed. 
(c) The granting or obtention of loans or financings which represent a significant 
amount of the aggregated capital of the Company. Additionally, the amount of 
any loans or financings in which the Company has entered into as of the disclosure 
of the Company’s last quarterly report, to the extent such amounts represent 5% 
or more of the total assets, liabilities or aggregated capital of the Company. 
(d) Relevant changes in strategic assets of the Company. 
(e) Material impairments, write-offs or restructurings of the most important liabilities 
of the Company or the companies controlled by the Company or in which the 
Company has Significant Influence. 
(f) Changes in dividend policy as well as any loans or financings in favor of the 
Company that involve restrictions or positive or negative covenants, such as the 
payment of dividends, or those involving modifications to the capital structure of 
the Company. 
(g) Projections of future revenues, earnings or losses. 
(h) Creation of a material direct or contingent financial obligation. 
(v) 
In connection with litigation and amendments to the applicable law: 
(a) Significant litigation or regulatory exposure due to actual or threatened litigation, 
investigation or enforcement activity, or significant developments related thereto. 
(b) Collective labor issues of the Company or the companies controlled by the 
Company or in which the Company has Significant Influence. 

 
 
(c) Judicial, administrative or arbitral proceedings which are relevant for the 
Company or the companies controlled by the Company or in which the Company 
has Significant Influence, as well as the resolutions thereof. 
(d) Amendments to laws or regulations that impact the business of the Company or 
the companies controlled by the Company or in which the Company has 
Significant Influence. 
Non-Public Information 
For purposes of this Policy, Material Events will not be considered publicly disclosed until they have 
been disclosed broadly to the marketplace (for example, included in a press release) and through the 
Mexican Stock Exchange and the investing public has had time to absorb the information fully. 
Information will be considered to be fully absorbed (1) if the information is released prior to 9:30 
a.m. U.S. Eastern Time on a “trading day,” by 9:30 a.m. U.S. Eastern Time on the first trading day 
after the information is released and (2) if the information is released on or after 9:30 a.m. U.S. 
Eastern Time on a trading day or on a day that is not a trading day, by 9:30 a.m. U.S. Eastern Time 
on the second trading day after the information is released. A “trading day” is a day on which the 
Stock Exchange is open for business. If, for example, the Company makes an announcement on 
Monday at 8:00 a.m. U.S. Eastern Time, the information in the announcement would be considered 
public starting at 9:30 a.m. U.S. Eastern Time on Tuesday (assuming all relevant days are “trading 
days”); and if the announcement is made on Monday 9:30 a.m. U.S. Eastern Time, the information 
in the announcement would be considered public starting at 9:30 a.m. U.S. Eastern Time on 
Wednesday (assuming all relevant days are “trading days”). 
b. Special Restrictions and Prohibitions; Blackout Periods and Trading Windows 
The following transactions present heightened legal risk or the appearance of improper or 
inappropriate conduct on the part of Company Persons and are restricted or prohibited as follows. 
The restrictions and prohibitions apply even if the relevant Company Person is not in possession of 
Privileged Information. 
Short Sales 
Short sales of a security (i.e., the sale of a security that the seller does not own) by their nature reflect 
an expectation that the value of the security will decline. Short sales can create inappropriate 
incentives and signal to the market a lack of confidence in the Company’s prospects. Accordingly, 
no Company Person (other than Material Shareholders) may engage in a short sale of Company 
Securities. 
Publicly Traded Options 
A put is an option to sell a security at a specific price before a set date, and a call is an option or right 
to buy a security at a specific price before a set date. Generally, put options are purchased when a 
person believes the value of a security will fall, and call options are purchased when a person believes 
the value of a security will rise. A transaction in options is, in effect, a bet on the short-term movement 
of the Company Securities, and it can give the appearance of trading on the basis of Privileged 
Information. Transactions in options may also focus a Company Person’s attention on short-term 
performance at the expense of the Company’s long-term objectives. Accordingly, no Company 

 
 
Person (other than Material Shareholders) may engage in a put, call or other derivative security 
transaction relating to Company Securities on an exchange or other organized market or otherwise. 
The restriction from the prior sentence does not apply to warrants issued by the Company; for the 
avoidance of doubt, the other restrictions described in this Policy do apply to warrants issued by the 
Company. 
Hedging Transactions 
Certain forms of hedging or monetization transactions, including zero-cost collars, equity swaps, 
exchange funds and forward sale contracts, allow a stockholder to lock in part of the value of his or 
her stock holdings, often in exchange for all or part of the potential for upside appreciation in the 
stock. These transactions allow the stockholder to continue to own the covered securities, but without 
the full risks and rewards of ownership. Because participating in these transactions may cause a 
Company Person to no longer have the same objectives as the Company’s other stockholders, no 
Company Person (other than Material Shareholders) may engage in such transactions. 
Margin Accounts and Pledges 
Securities held in margin accounts as collateral for a margined loan may be sold by the broker without 
the customer’s consent if the customer fails to meet a margin call. Similarly, securities pledged (or 
hypothecated) as collateral for a loan may be sold in foreclosure if the borrower defaults on the loan. 
A margin sale or foreclosure sale that occurs at a time when the pledgor is in possession of Privileged 
Information or otherwise is not permitted to trade in Company Securities would fall under the 
restrictions in this Policy on trading during such times. Therefore, any person who wishes to pledge 
Company Securities as collateral for a loan must inform the proposed transaction with the Compliance 
Office by submitting a request at least one week prior to the proposed execution of documents 
evidencing the proposed pledge. 
Restrictions applicable to Share Buybacks 
Any Company Person that is a member or secretary of the Board of Directors or Material 
Shareholders, prior to the realization of Transactions in Company Securities, shall inquire with the 
Company if it has transmitted or intends to transmit purchase or placement orders with respect to 
shares representing its own capital stock (i.e. transactions with the buyback fund), in which case, such 
persons shall refrain from transmitting purchase or sale orders, as applicable, unless in the context of 
public offerings. 
Since the purpose of the obligation to consult the Company prior to the execution of Transactions is 
to prevent the Company from defaulting the restriction set forth in the first paragraph of article 366 
of the LMV (i.e., that certain persons who are presumed to have privileged information may buy or 
sell Securities directly to the Company) and considering that, pursuant to article 56 of the LMV, the 
Company may only buy or sell such Securities through an authorized stock exchange in Mexico, such 
inquiry obligations will not be applicable to purchase or sale orders of Securities that take place 
outside an authorized stock exchange in Mexico (for example, orders to purchase or sell American 
Depositary Shares (ADSs) on shares representing the capital stock of the Company, which are placed 
on the New York Stock Exchange), since it is not legally possible for the Company to be on the other 
side of such transaction. To avoid any doubts, the inquiry obligations will not apply to the execution 
of Transactions in the context of a trading plan under Rule 10b5-1 of the Exchange Act, as it only 
operates outside of an authorized stock exchange in Mexico. 

 
 
Blackout Periods 
The Company has established quarterly blackout periods, and may impose additional, special 
blackout periods, each as described below. 
Quarterly Blackout Periods.  The quarterly blackout period starts on the end of each quarter and ends 
at (1) 9:30 a.m. U.S. Eastern Time on the first trading day following the release to the public of the 
Company’s earnings for the quarter if such release occurs prior to 9:30 a.m. U.S. Eastern Time on a 
trading day or (2) 9:30 a.m. U.S. Eastern Time on the second trading day following such release if 
such release occurs on or after 9:30 a.m. U.S. Eastern Time on a trading day or on a day that is not a 
trading day. Company Persons may not conduct any Transactions in Company Securities during such 
a quarterly blackout period. 
Short-swing Period. Company Persons shall not (a) acquire, whether directly or indirectly, any kind 
of Company Securities, during a 3-month period beginning as of the date on which such Company 
Person made the last sale of a Company Security; or (b) sell any kind of Company Securities, owned 
by the respective Company Person, whether directly or indirectly, during a 3-month period beginning 
as of the date on which such Company Person made the last acquisition of a Company Security. 
Without prejudice to the other terms of this Policy, the three-month blackout period shall not apply 
to Transactions in Company Securities which: 
(i) 
are carried out by stock market intermediaries, investment funds and insurance and 
bond companies, on their own behalf; 
(ii) 
represent acquisitions or disposals of securities by Company Persons or companies 
controlled by the Company, acquired in the context of stock purchase plans granted to 
employees, which have been previously approved at the shareholders’ meeting of the 
Company and that set forth a general and equivalent treatment for all officers and 
employees who maintain similar labor conditions; or 
(iii) 
are expressly authorized by the CNBV in the event of: 
(a) Corporate restructurings such as mergers, spin-offs, acquisitions or sales of assets 
representing at least 10% of the Company’s assets and sales for the last fiscal 
year. 
(b) Public offerings. 
(c) Pre-emptive rights regarding the subscription of stock shares. 
(d) Disposals of Company Securities belonging to one particular series in order to 
acquire Company Securities of a different series with the proceeds derived from 
such disposal. 
(e) Procurement of liquidity for emergency expenditures or those derived from acts of 
God or force majeur. 
(f) Any other event provided for in the LMV. 

 
 
Special Blackout Periods. Company Persons may not conduct any Transaction with Company 
Securities from (a) the moment in which they are in possession of Privileged Information and until 
(b) the second “trading day” after such information has been disclosed broadly to the marketplace 
(for example, included in a press release) and through the Mexican Stock Exchange. 
In addition, from time to time the Compliance Office may impose special blackout periods, during 
which Relevant Officers and other affected persons will be prohibited from engaging in Transactions 
in Company Securities. In the event of a special blackout period, the Compliance Office will notify 
the Relevant Officers and other affected persons, who will be prohibited from engaging in any 
Transaction in Company Securities until further written notice. The imposition of a special blackout 
period is itself Privileged Information, and the fact that it has been imposed may not be disclosed to 
others. 
Modification of a Blackout Period. To the extent permitted by applicable securities law, the 
Compliance Office may shorten, suspend, terminate or extend any blackout period at such time and 
for such duration as he or she deems appropriate given the relevant circumstances. Any persons 
affected by such a modification will be appropriately notified. 
c. Certain Exceptions 
 The exercise of stock options and/or warrants of the Company, within the framework of long-term 
incentive programs for personnel or any other program implemented by the Company, will not be 
subject to the restrictions provided in this Policy. 
Additional Procedures and Guidelines 
Transactions under Rule 10b5-1 Plans 
Implementation of a trading plan under Rule 10b5-1 under the Exchange Act allows a person to place 
a standing order with a broker to purchase or sell Company securities, so long as the plan specifies 
the dates, prices and amounts of the planned trades or establishes a formula for those purposes. Trades 
executed pursuant to a Rule 10b5-1 plan that meets the requirements listed below may generally be 
executed even though the person who established the plan may be in possession of Privileged 
Information at the time of the trade. 
A trading plan may only be established when a person is not in possession of Privileged Information 
and when a blackout period is not in effect. Anyone subject to this Policy who wishes to enter into a 
Rule 10b5-1 plan must submit the trading plan to the Compliance Office for prior, written approval. 
All Rule 10b5-1 plans must be placed through a broker satisfactory to the Company. Subsequent 
termination or modifications to any Rule 10b5-1 plan must also be pre-approved by the Compliance 
Office. 
Whether or not pre-approval will be granted will depend on all the facts and circumstances at the 
time, but the following guidelines should be kept in mind: 
(i) 
The trading plan must be executed outside of Mexico, apply only to transactions to be 
conducted in the New York Stock Exchange and provide terms that will not breach the 
short-swing period, and the relevant Company Person shall represent to the satisfaction 
of the Company that such plan and its implementation will have no effect in Mexico;  

 
 
(ii) 
The trading plan must be in writing and entered into only when a blackout period is 
not in effect and when the individual is not in possession of Privileged Information; 
(iii) 
The trading plan must be adopted in good faith and not as part of a plan or scheme to 
evade the anti-fraud rules under the federal securities laws, and the Company Person 
must at all times act in good faith with respect to the trading plan; 
(iv) 
Any Relevant Officer or Material Shareholder adopting a trading plan must certify in 
writing, in the terms of the trading plan agreement, that, at the time of the adoption of 
a trading plan (whether a new plan or due to a Termination Modification, as defined 
below): (1) they are not aware of Privileged Information about the Company or the 
Company’s securities; and (2) they are adopting the plan in good faith and not as part 
of a plan or scheme to evade the prohibitions of Rule 10b-5; 
(v) 
Any modification to the amount, price or timing of the purchase or sale of securities 
under a trading plan, as well as any change to an algorithm or computer program 
affecting such factors shall be deemed to be a termination of the current trading plan 
and the adoption of a new trading plan for purposes of restarting the Cooling-Off 
Period (as defined below) (any such modification, a “Termination Modification”); 
(vi) 
The first trade made following adoption or Termination Modification of a trading plan 
of a (A) Relevant Officer or Material Shareholder may take place no sooner than the 
later of (i) 90 calendar days from adoption or modification and (ii) the second business 
day after the Company announces its financial results for the quarter in which the 
trading plan is adopted or amended by a Termination Modification (but in any event, 
not to exceed 120 days following the trading plan’s adoption or any Termination 
Modification of such trading plan), or (B) Company Persons other than Relevant 
Officers and Material Shareholders may take place no sooner than 30 calendar days 
from the adoption or modification of the plan (collectively, the “Cooling-Off Period”); 
(vii) 
The individual may not have more than one trading plan in effect at any given time, 
except for (i) a single plan entered into with multiple brokers or where a broker is 
replaced (so long as such replacement does not change the purchase or sale amount, 
price or date of purchases); (ii) where there is an earlier- and later-commencing plan 
designed to operate in sequence, such that one commences after termination of the 
other and incorporates an “effective cooling off period”; (iii) a single “sell-to-cover” 
plan (intended to cause the sale of securities to satisfy withholding obligations arising 
from the vesting of stock-based compensation and other compensation awards not 
subject to individual discretion as to timing of vesting, but not options) that exists 
concurrently with another plan and (iv) any other situation permitted by applicable law 
and subject to the prior approval of the Compliance Office; 
(viii) If a trading plan is meant to effect a single transaction, an individual may not have had 
another single-trade plan (10b5-1 or otherwise) during the prior 12-month period; 
(ix) 
The trading plan must permit its termination by the Company at any time when the 
Company believes that trading pursuant to its terms may not lawfully occur;  
(x) 
Any Termination Modification must be made only during a non-blackout period when 
the person is not in possession of Privileged Information and transactions under any 
amended plan may not commence until the Cooling-Off Period beginning at the 
execution of the Termination Modification; 
(xi) 
Trading plans do not obviate the need to file Form 144 and the fact that a reported 
transaction was made or is to be made pursuant to a trading plan should be noted on 
the applicable Form; and 
(xii) 
Information regarding adoption, modification, termination and material terms of any 

 
 
trading plan (including any modification or change to the plan) may be required to be 
disclosed in the Company’s quarterly reports filed on Form 6-K and annual report on 
Form 20-F; and 
(xiii) A copy of the executed version of any pre-cleared trading plan must be provided to 
the Compliance Office for retention in accordance with the Company’s Record 
Retention Policy.  
Confidentiality of All Non-Public Information 
Company Persons must maintain the confidentiality of the Company’s non-public information. In the 
event a Company Person receives any inquiry or request for information (particularly financial results 
and/or projections, and including to affirm or deny information about the Company), from any person 
or entity outside the Company, such as a stock analyst, and it is not part of such Company Person’s 
regular corporate duties to respond to such inquiry or request, the inquiry should be referred to 
Investor Relations, which will determine whether such inquiry should also be forwarded to the 
Compliance Office.  
Individual Responsibility 
Each Company Person has the individual responsibility to comply with this Policy. A Company 
Person may, from time to time, have to forgo a proposed Transaction in Company Securities even if 
he or she planned to make such transaction before learning of the Privileged Information. While the 
Compliance Office can and should be consulted regarding the application of this Policy, including 
the appropriateness of engaging in a particular transaction at a particular time, the responsibility for 
adhering to this Policy and avoiding unlawful transactions, and ensuring that Related Persons do the 
same, rests with each Company Person.  
Post-Termination Transactions 
This Policy applies even after termination of employment or service with the Company. If a Company 
Person is in possession of Privileged Information when his or her employment or service terminates, 
that person may not conduct Transactions in Company Securities (or another company’s securities, 
as described in this Policy) until such information has become public or is no longer material. 
VII. 
Special Reporting on certain Transactions  
a. LMV Threshold – Acquisitions between 10% and 30% of the stock shares of the 
Company 
Each Company Person must comply with Article 109 of the LMV, which provides that any person or 
group of persons acquiring, whether directly or indirectly, within or outside the Stock Exchange, 
through one or several simultaneous or subsequent transactions of any nature, ordinary stock shares 
of a company granting any such persons title over 10% or more and less than 30% of such shares, 
shall disclose such situation to the public no later than the following business day of the occurrence 
of such event, through the Stock Exchange and in accordance with the terms and conditions the Stock 
Exchange sets forth. In addition, such situation shall be informed to the CNBV within the same term 
referred to above. Regarding groups of persons, the individual positions of each member thereof shall 
be disclosed. 

 
 
b. LMV Threshold – 5% Increase or Reduction 
To the extent applicable, each Company Person must comply with Article 110 of the LMV, which 
provides that any related parties of a company that directly or indirectly increase or reduce their 
position in the ordinary stock shares of the relevant company by 5%, through one or several 
simultaneous or subsequent transactions, shall disclose such situation to the public no later than the 
following business day of the occurrence of such event, through the Stock Exchange and in 
accordance with the terms and conditions the Stock Exchange sets forth. 
In addition, the respective person shall express its intention or absence thereof to acquire a position 
that grants he or she with voting rights of 20% or more over the respective company’s stock capital 
(“Significant Influence”). 
c. LMV Threshold – Persons with a 10% interest or higher in the Company’s stock 
shares, members of the Board of Directors and Relevant Officers 
To the extent applicable, each Company Person must comply with Article 111 of the LMV, which 
provides that any person that directly or indirectly hold a 10% interest or higher in a company’s stock 
shares, as well as the members of the board of directors and Relevant Officers of such company, shall 
inform the CNBV of and, as the case may be, disclose to the public any acquisition or disposal thereof. 
For purposes of the foregoing and pursuant to Articles 49 bis and 49 bis 1 of the Securities 
Regulations, the corresponding persons shall inform the CNBV and the Stock Exchange of the 
acquisitions or disposals conducted: 
(i) 
During a calendar quarter, provided that the operated amount during such period is 
equal or greater than the equivalent in Mexican Pesos of 1,000,000 investment units 
(“UDIs”) (considering the equivalence rate as of the last business day of the respective 
quarter), through a notice delivered within the 5 business days following the closing 
of the respective quarter; and 
(ii) 
During a 5-business days term, in the event the total operated amount is equal or 
greater than 1,000,000 UDIs (considering the equivalence rate as of the last business 
day of the respective quarter), through a notice delivered within the next business day 
to that in which such amount has been reached. 
Such notices shall not be required when the aforementioned thresholds are not reached within the 
terms indicated above. 
d. Company’s By-Laws’ Threshold (poison pill) 
Pursuant to Article Ninth of the Company’s by-laws and subject to certain exceptions expressly set 
forth therein, any direct or indirect acquisition of the Company’s stock shares, or attempted 
acquisition of thereof, of any nature and however denominated, under any title or legal scheme, 
intended to be performed, whether through one or several simultaneous or subsequent transactions of 
any legal nature, without any time limit between them, whether through the Stock Exchange or not, 
in Mexico or abroad, including transactions structured as mergers, corporate reorganizations, 
spinoffs, consolidations, execution of collateral or other similar transactions or legal actions (any of 
such operations, an "Acquisition"), by one or more persons, related persons, group of persons, 
business group or consortium, shall require the favorable prior written approval of the Board of 

 
 
Directors in order to be valid, each time the number of shares to be acquired plus the shares previously 
held by the respective purchaser results in such purchaser holding 10% or more of the total shares 
outstanding. Once such interest is reached, any subsequent Acquisition of shares that results in such 
persons, related persons, group of persons, business group or consortium holding an additional 2% 
or more of the total shares outstanding shall be notified to the Board of Directors at the corporate 
domicile of the Company (through the chairman of the Board of Directors with a copy to the non-
member secretary of the Board of Directors).  
For a more detailed description of the provisions intended to avoid changes in control, please refer to 
Article Ninth of the Company’s by-laws.

Ladies and Gentlemen: 
 
Pursuant to your request, this report of third party presents an independent 
evaluation, as of December 31, 2024, of the extent of the estimated net proved oil, 
condensate, natural gas liquids (NGL), and gas reserves of certain properties in 
Argentina and Mexico in which Vista Energy S.A.B. de C. V. (Vista) has represented 
it holds an interest. This evaluation was completed on January 27, 2025. Vista has 
represented that these properties account for 100 percent on a net equivalent barrel 
basis of Vista’s net proved reserves as of December 31, 2024. The net proved reserves 
estimates have been prepared in accordance with the reserves definitions of Rules 4–
10(a) (1)–(32) of Regulation S–X of the United States Securities and Exchange 
Commission (SEC). This report was prepared in accordance with guidelines specified 
in Item 1202 (a)(8) of Regulation S–K and is to be used for inclusion in certain SEC 
filings by Vista. 
 
Reserves estimates included herein are expressed as net reserves. Gross 
reserves are defined as the total estimated petroleum remaining to be produced from 
these properties after December 31, 2024. Net reserves are defined as that portion 
of the gross reserves attributable to the interests held by Vista after deducting all 
interests held by others. Vista has advised that its government royalty obligations 
are paid in cash; therefore, net reserves have not been reduced in consideration of 
these royalty obligations. 

2 
DEGOLYER AND MACNAUGHTON
 
 
Estimates of reserves should be regarded only as estimates that may change 
as further production history and additional information become available. Not 
only are such estimates based on that information which is currently available, but 
such estimates are also subject to the uncertainties inherent in the application of 
judgmental factors in interpreting such information. 
 
Information used in the preparation of this report was obtained from 
Vista. In the preparation of this report we have relied, without independent 
verification, upon information furnished by Vista with respect to the property 
interests being evaluated, production from such properties, current costs of operation 
and development, current prices for production, agreements relating to current and 
future operations and sale of production, and various other information and data that 
were accepted as represented. A field examination was not considered necessary for 
the purposes of this report. 
 
Definition of Reserves 
 
Petroleum reserves estimated in this report are classified as proved. Only 
proved reserves have been evaluated for this report. Reserves classifications used 
in this report are in accordance with the reserves definitions of Rules 4–10(a) 
(1)–(32) of Regulation S–X of the SEC. Reserves are judged to be economically 
producible in future years from known reservoirs under existing economic and 
operating conditions and assuming continuation of current regulatory practices 
using conventional production methods and equipment. In the analyses of 
production-decline curves, reserves were estimated only to the limit of economic 
rates of production under existing economic and operating conditions using prices 
and costs consistent with the effective date of this report, including consideration 
of changes in existing prices provided only by contractual arrangements but not 
including escalations based upon future conditions. The petroleum reserves are 
classified as follows: 
 
Proved oil and gas reserves – Proved oil and gas reserves are those 
quantities of oil and gas, which, by analysis of geoscience and 
engineering data, can be estimated with reasonable certainty to be 
economically producible—from a given date forward, from known 
reservoirs, and under existing economic conditions, operating methods, 
and government regulations—prior to the time at which contracts 
providing the right to operate expire, unless evidence indicates that 
renewal is reasonably certain, regardless of whether deterministic 

3 
DEGOLYER AND MACNAUGHTON
 
 
or probabilistic methods are used for the estimation.  The project 
to extract the hydrocarbons must have commenced or the operator 
must be reasonably certain that it will commence the project within 
a reasonable time. 
 
(i) The area of the reservoir considered as proved includes: 
(A) The area identified by drilling and limited by fluid contacts, 
if any, and (B) Adjacent undrilled portions of the reservoir that 
can, with reasonable certainty, be judged to be continuous with it 
and to contain economically producible oil or gas on the basis of 
available geoscience and engineering data. 
 
(ii) In the absence of data on fluid contacts, proved quantities in a 
reservoir are limited by the lowest known hydrocarbons (LKH) 
as seen in a well penetration unless geoscience, engineering, 
or performance data and reliable technology establishes a lower 
contact with reasonable certainty. 
 
(iii) Where direct observation from well penetrations has 
defined a highest known oil (HKO) elevation and the potential 
exists for an associated gas cap, proved oil reserves may be 
assigned in the structurally higher portions of the reservoir 
only if geoscience, engineering, or performance data and reliable 
technology establish the higher contact with reasonable certainty. 
 
(iv) Reserves which can be produced economically through 
application of improved recovery techniques (including, but 
not limited to, fluid injection) are included in the proved 
classification when: 
(A) Successful testing by a pilot project in an area of the reservoir 
with properties no more favorable than in the reservoir as a 
whole, the operation of an installed program in the reservoir or an 
analogous reservoir, or other evidence using reliable technology 
establishes the reasonable certainty of the engineering analysis 
on which the project or program was based; and (B) The project 
has been approved for development by all necessary parties and 
entities, including governmental entities. 
 
(v) Existing economic conditions include prices and costs at which 
economic producibility from a reservoir is to be determined. The 

4 
DEGOLYER AND MACNAUGHTON
 
 
price shall be the average price during the 12-month period prior 
to the ending date of the period covered by the report, determined 
as an unweighted arithmetic average of the first-day-of-the-month 
price for each month within such period, unless prices are defined 
by contractual arrangements, excluding escalations based upon 
future conditions. 
 
Developed oil and gas reserves – Developed oil and gas reserves are 
reserves of any category that can be expected to be recovered: 
 
(i) Through existing wells with existing equipment and operating 
methods or in which the cost of the required equipment is 
relatively minor compared to the cost of a new well; and 
 
(ii) Through installed extraction equipment and infrastructure 
operational at the time of the reserves estimate if the extraction 
is by means not involving a well. 
 
Undeveloped oil and gas reserves – Undeveloped oil and gas reserves 
are reserves of any category that are expected to be recovered from new 
wells on undrilled acreage, or from existing wells where a relatively 
major expenditure is required for recompletion. 
 
(i) Reserves on undrilled acreage shall be limited to those 
directly offsetting development spacing areas that are reasonably 
certain of production when drilled, unless evidence using 
reliable technology exists that establishes reasonable certainty of 
economic producibility at greater distances. 
 
(ii) Undrilled locations can be classified as having undeveloped 
reserves only if a development plan has been adopted indicating 
that they are scheduled to be drilled within five years, unless the 
specific circumstances justify a longer time. 
 
(iii) Under no circumstances shall estimates for undeveloped 
reserves be attributable to any acreage for which an application 
of fluid injection or other improved recovery technique is 
contemplated, unless such techniques have been proved effective 
by actual projects in the same reservoir or an analogous 
reservoir, as defined in [section 210.4–10 (a) Definitions], or by 

5 
DEGOLYER AND MACNAUGHTON
 
 
other evidence using reliable technology establishing reasonable 
certainty. 
 
Methodology and Procedures 
 
Estimates of reserves were prepared by the use of appropriate geologic, 
petroleum engineering, and evaluation principles and techniques that are in 
accordance with the reserves definitions of Rules 4–10(a) (1)–(32) of Regulation 
S–X of the SEC and with practices generally recognized by the petroleum industry 
as presented in the publication of the Society of Petroleum Engineers entitled 
“Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves 
Information (revised June 2019) Approved by the SPE Board on 25 June 2019” and 
in Monograph 3 and Monograph 4 published by the Society of Petroleum Evaluation 
Engineers. The method or combination of methods used in the analysis of each 
reservoir was tempered by experience with similar reservoirs, stage of development, 
quality and completeness of basic data, and production history. 
 
Based on the current stage of field development, production performance, the 
development plan provided by Vista, and analyses of areas offsetting existing wells 
with test or production data, reserves were classified as proved. 
 
The undeveloped reserves estimates were based on opportunities identified in 
the plan of development provided by Vista. 
 
Vista has represented that its senior management is committed to the 
development plan provided by Vista and that Vista has the financial capability to 
execute the development plan, including the drilling and completion of wells and the 
installation of equipment and facilities. 
 
For depletion-type reservoirs or those whose performance disclosed a reliable 
decline in producing-rate trends or other diagnostic characteristics, reserves were 
estimated by the application of appropriate decline curves or other performance 
relationships. In the analyses of production-decline curves, reserves were estimated 
only to the limits of economic production as defined under the Definition of Reserves 
heading of this report or the expiration of the concession, as appropriate. 
 
In certain cases, reserves were estimated by incorporating elements of 
analogy with similar wells or reservoirs for which more complete data were available. 

6 
DEGOLYER AND MACNAUGHTON
 
 
In the evaluation of undeveloped reserves, type-well analysis was performed 
using well data from wells drilled through December 31, 2024, and analogous 
reservoirs for which more complete historical performance data were available. 
 
For the evaluation of unconventional reservoirs, a performance-based 
methodology integrating the appropriate geology and petroleum engineering data 
was utilized for this report.  Performance-based methodology primarily includes 
(1) production diagnostics, (2) decline-curve analysis, and (3) model-based analysis (if 
necessary, based on availability of data). Production diagnostics include data quality 
control, identification of flow regimes, and characteristic well performance behavior. 
These analyses were performed for all well groupings (or type-curve areas). 
 
Characteristic rate-decline profiles from diagnostic interpretation were 
translated to modified hyperbolic rate profiles, including one or multiple b-exponent 
values followed by an exponential decline. Based on the availability of data, 
model-based analysis may be integrated to evaluate long-term decline behavior, 
the effect of dynamic reservoir and fracture parameters on well performance, and 
complex situations sourced by the nature of unconventional reservoirs. 
 
Data provided by Vista from wells drilled through December 31, 2024, and 
made available for this evaluation were used to prepare the reserves estimates 
herein. These reserves estimates were based on consideration of monthly production 
data available for certain properties only through October 2024. Estimated 
cumulative production, as of December 31, 2024, was deducted from the estimated 
gross ultimate recovery to estimate gross reserves. This required that production be 
estimated for 2 months. 
 
Oil and condensate reserves estimated herein are to be recovered by 
normal field separation. NGL reserves estimated herein include pentanes and 
heavier fractions (C5+) and liquefied petroleum gas (LPG), which consists primarily 
of propane and butane fractions, and are the result of low-temperature plant 
processing. Oil, condensate, C5+, and LPG reserves included herein are expressed in 
thousands of barrels (103bbl). In these estimates, 1 barrel equals 42 United States 
gallons. For reporting purposes, oil and condensate reserves have been estimated 
separately and are presented herein as a summed quantity. 
 
Gas quantities estimated herein are expressed as marketable gas and sales 
gas.  Marketable gas is defined as the total gas produced from the reservoir 
after reduction for shrinkage resulting from field separation; processing, including 
removal of the nonhydrocarbon gas to meet pipeline specifications; and flare and

other losses but not from fuel usage. Sales gas is defined as the total gas to be 
produced from the reservoirs, measured at the point of delivery, after reduction 
for fuel usage, flare, and shrinkage resulting from field separation and processing. 
Gas reserves estimated herein are reported as marketable gas and sales gas. Gas 
quantities are expressed at a temperature base of 60 degrees Fahrenheit (◦F) and 
at a pressure base of 14.696 pounds per square inch absolute (psia). Gas quantities 
included in this report are expressed in millions of cubic feet (106ft3). 
 
Gas quantities are identified by the type of reservoir from which the gas 
will be produced. Nonassociated gas is gas at initial reservoir conditions with no 
oil present in the reservoir. Associated gas is both gas-cap gas and solution gas. 
Gas-cap gas is gas at initial reservoir conditions and is in communication with an 
underlying oil zone. Solution gas is gas dissolved in oil at initial reservoir conditions. 
Gas quantities estimated herein include both associated and nonassociated gas. 
 
Primary Economic Assumptions 
 
This report has been prepared using initial prices, expenses, and costs 
provided by Vista in United States dollars (U.S.$). Future prices were estimated 
using guidelines established by the SEC and the Financial Accounting Standards 
Board (FASB). The following economic assumptions were used for estimating the 
reserves reported herein: 
 
Oil, Condensate, C5+, and LPG Prices 
 
Vista has represented that the oil, condensate, C5+, and LPG 
prices were based on a reference price, calculated as the 
unweighted arithmetic average of the first-day-of-the-month price 
for each month within the 12-month period prior to the end of 
the reporting period, unless prices are defined by contractual 
agreements. Vista supplied differentials to a Brent reference 
price of U.S.$80.42 per barrel and the prices were held constant 
thereafter. For the properties in Argentina, the volume-weighted 
average adjusted product prices attributable to the estimated 
proved reserves were U.S.$69.44 per barrel of oil, condensate, 
and C5+ and U.S.$25.72 per barrel for LPG. For the properties 
in Mexico, the volume-weighted average adjusted product price 
attributable to the estimated proved reserves was U.S.$61.48 per 
barrel of oil. These prices were not escalated for inflation.

DEGOLYER AND MACNAUGHTON
 
 
Gas Prices 
 
Vista has represented that the gas prices for the properties 
evaluated herein are defined by contractual agreements based on 
specific market conditions. For the properties in Argentina, for 
certain volumes of gas Vista is paid an incentive gas price that 
is subsidized by the Argentine government through 2028. The 
incentive volume-weighted average gas sales prices are U.S.$4.10 
per thousand cubic feet (103ft3) of gas for 2025, U.S.$4.04 per 
103ft3 of gas for 2026, U.S.$4.22 per 103ft3 of gas for 2027, 
and U.S.$4.21 per 103ft3 of gas for 2028. The volume-weighted 
average adjusted product price attributable to the estimated 
proved reserves for 2029 forward is U.S.$3.77 per 103ft3 of gas. 
The volume-weighted average adjusted product price attributable 
to the estimated proved reserves for the properties located in 
Mexico was U.S.$2.79 per 103ft3 of gas. 
 
Operating Expenses, Capital Costs, and Abandonment Costs 
 
Estimates of operating expenses and future capital expenditures, 
provided by Vista and based on existing economic conditions, 
were held constant for the lives of the properties. In certain 
cases, future expenditures, either higher or lower than current 
expenditures, may have been used because of anticipated changes 
in operating conditions, but no general escalation that might 
result from inflation was applied. Abandonment costs, which are 
those costs associated with the removal of equipment, plugging 
of wells, and reclamation and restoration associated with the 
abandonment, were provided by Vista for all properties and 
were not adjusted for inflation. Operating expenses, capital 
costs, and abandonment costs were considered, as appropriate, in 
determining the economic viability of the undeveloped reserves 
estimated herein. 
 
In our opinion, the information relating to estimated proved reserves of 
oil, condensate, C5+, LPG, and gas contained in this report has been prepared 
in accordance with Paragraphs 932-235-50-4, 932-235-50-6, 932-235-50-7, and 
932-235-50-9 of the Accounting Standards Update 932-235-50, Extractive Industries 
– Oil and Gas (Topic 932): Oil and Gas Reserve Estimation and Disclosures 
(January 2010) of the FASB and Rules 4–10(a)(1)–(32) of Regulation S–X and Rules

DEGOLYER AND MACNAUGHTON
 
 
302(b), 1201, 1202(a) (1), (2), (3), (4), (8), and 1203(a) of Regulation S–K of the 
SEC; provided, however, that estimates of proved developed and proved undeveloped 
reserves are not presented at the beginning of the year. 
 
To the extent the above-enumerated rules, regulations, and statements 
require determinations of an accounting or legal nature, we, as engineers, are 
necessarily unable to express an opinion as to whether the above-described 
information is in accordance therewith or sufficient therefor. 
 
Summary of Conclusions 
 
DeGolyer and MacNaughton has performed an independent evaluation of the 
extent of the estimated net proved oil, condensate, NGL, and gas reserves of certain 
properties in which Vista has represented it holds an interest. The estimated net 
proved reserves, as of December 31, 2024, of the properties evaluated herein were 
based on the definition of proved reserves of the SEC and are summarized as follows, 
expressed in thousands of barrels (103bbl) and millions of cubic feet (106ft3):

While the oil and gas industry may be subject to regulatory changes from time 
to time that could affect an industry participant's ability to recover its reserves, we 
are not aware of any such governmental actions which would restrict the recovery of 
the December 31, 2024, estimated reserves.
