**EXPLANATORY NOTE** 

Petróleos Mexicanos is the state-owned public oil and gas company of the United Mexican States, which we refer to as Mexico, wholly owned by the Federal Government of Mexico, which we refer to as the Mexican Government. Petróleos Mexicanos is a legal entity empowered to own property and carry on business in its own name. Pursuant to the Energy Reform Decree (as defined herein) and the *Ley de la Empresa Pública del Estado, Petróleos Mexicanos* (the "2025 Petróleos Mexicanos Law"), as of March 19, 2025, our three former subsidiary entities, *Pemex Exploración y Producción* ("Pemex Exploration and Production"), *Pemex Transformación Industrial* ("Pemex Industrial Transformation") and *Pemex Logística* ("Pemex Logistics"), have been dissolved and all of their assets, liabilities, rights and obligations have been assumed by Petróleos Mexicanos, which has been transformed from a productive state-owned company into a state-owned public company. This annual report contains certain information regarding our former subsidiary entities for the years ended December 31, 2024 and 2023. For the year ended December 31, 2025, due to their consolidation into Petróleos Mexicanos, we have ceased to report information regarding our former subsidiary entities. For more information about Mexico's recent energy reform and its impact on our business, see "*Special Note Regarding Mexican Energy Reform*" and "*Item 4—Information on the Company—History and Development—Recent Energy Reform*."

In addition, a number of subsidiary companies that are defined in Note 1 and listed in Note 5 to our consolidated financial statements incorporated in Item 18, which we refer to as our subsidiary companies, are incorporated into the consolidated financial statements; these subsidiary companies are also identified with their corresponding ownership percentages in "–*–Consolidated Structure of PEMEX*" on page 4. Petróleos Mexicanos and the subsidiary companies (including, for the years ended December 31, 2023 and 2024, the subsidiary entities) are collectively referred to as "PEMEX" or "we." See "*Item 4—Information on the Company—History and Development—Corporate Structure*" for more details.

References herein to "U.S. $," "$," "U.S. dollars" or "dollars" refers to dollars of the United States of America. References herein to "pesos" or "Ps." are to the legal currency of Mexico. References herein to "euros" or "€" are to the legal currency of the European Economic and Monetary Union. References herein to "pounds sterling" or "£" are to the legal currency of the United Kingdom. References herein to "Swiss francs" are to the legal currency of the Swiss Confederation. References herein to "Japanese yen" or "¥" are to the legal currency of Japan. References herein to "Australian dollars" are to the legal currency of Australia. The term "billion" as used herein means one thousand million. Amounts in this annual report are rounded, and the totals may therefore not precisely equal the sum of the numbers presented.

Our consolidated financial statements included in this annual report were prepared in accordance with IFRS Accounting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB"). In addition, these consolidated financial statements were audited in accordance with the International Standards on Auditing, as required by the *Ley del Mercado de Valores* (Securities Market Law) and the *Disposiciones de carácter general aplicables a las emisoras de valores y a otros participantes del mercado de valores* (General Provisions applicable to issuers of securities and other participants in the securities market) in each case, of Mexico, for purposes of filing with the *Comisión Nacional Bancaria y de Valores* (National Banking and Securities Commission, or the CNBV) and the *Bolsa Mexicana de Valores, S.A.B. de C.V.* (Mexican Stock Exchange), and in accordance with the standards of the Public Company Accounting Oversight Board (United States), or PCAOB, for purposes of filings with the U.S. Securities and Exchange Commission, or the SEC.

The regulations of the SEC do not require foreign private issuers that prepare their financial statements on the basis of IFRS to reconcile such financial statements to United States Generally Accepted Accounting Principles, which we refer to as U.S. GAAP. Accordingly, while we have in the past reconciled our consolidated financial statements prepared in accordance with *Normas de Información Financiera Mexicanas* (Mexican Financial Reporting Standards) to U.S. GAAP, those reconciliations are no longer presented in our filings with the SEC. We do, however, continue to provide the disclosure required under the U.S. Financial Accounting Standards Board Accounting Standards Codification (ASC) Topic 932 "Extractive Activities—Oil and Gas" (which we refer to as ASC Topic 932), as this is required regardless of the basis of accounting on which we prepare our consolidated financial statements.

We maintain our consolidated financial statements and accounting records in pesos. Unless otherwise indicated, we have translated all peso amounts to U.S. dollars in this Form 20-F, including all convenience translations of our consolidated financial statements included herein, at an exchange rate of Ps. Ps.17.9667 = U.S. $1.00, which is the exchange rate that the *Secretaría de Hacienda y Crédito Público* (the "Ministry of Finance and Public Credit") instructed us to use on December 31, 2025. You should not construe these translations from pesos into dollars as actually representing

**SPECIAL NOTE REGARDING MEXICAN ENERGY REFORM**

On October 17, 2024, the Mexican Congress approved amendments to Articles 25, 27 and 28 of the *Constitución Política de los Estados Unidos Mexicanos* (the "Mexican Constitution"), which were subsequently approved by a majority of Mexico's state legislatures and signed into law by the President Claudia Sheinbaum Pardo. On October 31, 2024, these amendments were published in the *Diario Oficial de la Federación* (the "Official Gazette of the Federation") as the *Decreto por el que se reforman el párrafo quinto del artículo 25, los párrafos sexto y séptimo del artículo 27 y el párrafo cuarto del artículo 28 de la Constitución Política de los Estados Unidos Mexicanos, en materia de áreas y empresas estratégicas* (Decree amending Paragraph 5 of Article 5, Paragraphs 6 and 7 of Article 27 and Paragraph 4 of Article 28 of the Mexican Constitution regarding Strategic Enterprises, or the "Energy Reform Decree").

The Energy Reform Decree took effect on November 1, 2024 and transformed the legal regime of Petróleos Mexicanos from an *empresa productiva del Estado* (productive state-owned company) to an *empresa pública del Estado* (state-owned public company). The Energy Reform Decree included *artículos transitorios* (transitional articles) requiring the Mexican Congress to adjust, amend or otherwise modify any relevant legislation required to give effect to the Energy Reform Decree within 180 calendar days (such implementing legislation, the "Secondary Legislation"). On March 12, 2025, the Mexican Congress approved the Secondary Legislation, which was subsequently signed into law by President Claudia Sheinbaum Pardo and published in the Official Gazette of the Federation on March 18, 2025. The Energy Reform Decree and the Secondary Legislation include important modifications to our legal framework, corporate structure and corporate governance, including six new laws, including the 2025 Petróleos Mexicanos Law, and amendments to existing laws. For more information, see "*Item 4—Information on the Company—History and Development—Recent Energy Reform*."

Separately, following the enactment of the Energy Reform Decree and as part of a broader institutional reform agenda, on November 28, 2024, the Mexican Congress approved amendments to certain Articles of the Mexican Constitution aimed at simplifying the structure of independent government agencies. These amendments were subsequently approved by a majority of Mexico's state legislatures, signed into law by President Claudia Sheinbaum Pardo and published in the Official Gazette of the Federation on December 20, 2024 (the "Organic Simplification Decree"). The implementing legislation relating to the Organic Simplification Decree was included in the Secondary Legislation and took effect on March 19, 2025. As a result, the Comisión Nacional de Hidrocarburos (National Hydrocarbons Commission) and the Comisión Reguladora de Energía (Energy Regulatory Commission, or "CRE") were dissolved, and their regulatory functions were transferred to the Ministry of Energy and the new Comisión Nacional de Energía (National Energy Commission), a deconcentrated regulatory entity within the Ministry of Energy. For more information, see "*Item 4—Information on the Company—History and Development—Recent Energy Reform—New Legal Regime*" and "*Item 4—General Regulatory Framework.*"

Pursuant to the 2025 Petróleos Mexicanos Law, Petróleos Mexicanos is wholly owned by the Mexican Government and categorized under the Ministry of Energy. For more information, see "*Item 4—Information on the Company—History and Development—Recent Energy Reform—New Legal Regime*" and "*Item 4—General Regulatory Framework*."

Moreover, our former subsidiary entities, Pemex Exploration and Production, Pemex Industrial Transformation and Pemex Logistics, were dissolved effective as of March 19, 2025. Upon dissolution, all assets, liabilities, rights and obligations of the subsidiary entities were transferred to, and assumed by, Petróleos Mexicanos at historical cost without gain or loss, and Petróleos Mexicanos became the legal successor of the subsidiary entities as a matter of Mexican law. On May 22, 2025, the Board of Directors of Petróleos Mexicanos approved the *Estatuto Orgánico de Petróleos Mexicanos* (Organic Statute of Petróleos Mexicanos or the "New Organic Statute"). The New Organic Statute was published in the Official Gazette of the Federation on May 30, 2025, and became effective on June 1, 2025. On September 12, 2025, an amendment to the New Organic Statute, previously approved by the Board of Directors of Petróleos Mexicanos, was published in the Official Gazette of the Federation. The New Organic Statute establishes the new structure and organization of Petróleos Mexicanos. For more information, see "*Item 4—Information on the Company—History and Development—Recent Energy Reform—New Legal Regime*" and "*Item 4—Information on the Company—History and Development—Corporate Structure*."

**PRESENTATION OF INFORMATION CONCERNING RESERVES** 

The proved hydrocarbon reserves included in this report for the year ended December 31, 2025, are those that we have the right to extract and sell based on assignments granted to us by the Mexican Government.

The estimates of our proved reserves of crude oil and natural gas for the five years ended December 31, 2025 included in this report have been calculated according to the technical definitions required by the SEC. DeGolyer and MacNaughton Corp. (which we refer to as "DeGolyer and MacNaughton"), GLJ Ltd. (which we refer to as "GLJ") and Ryder Scott Company L.P. (which we refer to as "Ryder Scott") conducted reserves audits of our estimates of our proved hydrocarbon reserves as of December 31, 2025 or January 1, 2026, as applicable. All reserves estimates involve some degree of uncertainty. For a description of the risks relating to reserves and reserves estimates, see *"Item 3—Key Information—Risk Factors—Risk Factors Related to our Relationship with the Mexican Government—Hydrocarbon reserves are based on estimates, which are uncertain and subject to revisions*,*" "—We must make significant capital expenditures to sustain our current production levels, and to maintain, as well as increase, the proved hydrocarbon reserves assigned to us by the Mexican Government. Reductions in our revenue, adjustments to our capital expenditures budget or an inability to obtain financing may limit our ability to make capital investments"* and *"—The Mexican nation, not us, owns the hydrocarbon reserves located in Mexico, and our right to continue to extract these reserves is subject to the approval of the Ministry of Energy*.*"*

**Risk Factors Related to Our Operations** 

***We have a substantial amount of indebtedness and other liabilities and are exposed to significant liquidity constraints, which could make it difficult for us to obtain financing on favorable terms and could adversely affect our financial condition, results of operations and ability to repay our debt and, ultimately, our ability to operate as a going concern without additional support from the Mexican Government, which we may not receive.***

We have a substantial amount of debt, which we have incurred primarily to fund our operating expenses and finance our capital investment projects. Despite reductions in our tax burden, our cash flow from operations in recent years has not been sufficient to fund our capital expenditures and other expenses and, accordingly, we face significant indebtedness. Therefore, in order to develop our assigned hydrocarbon reserves, service our indebtedness and amortize scheduled debt maturities, we may need to obtain funds from a broad range of sources, in addition to continuing efficiency and cost-cutting initiatives. There can be no assurances that we will continue to have access to capital on favorable terms or any terms at all. During 2025, we received support from the Mexican Government mainly to strengthen our financial condition, and such additional support may not be available in upcoming years.

As of December 31, 2025, our total indebtedness, including accrued interest, was Ps. 1,531.3 billion (U.S.$85.2 billion), in nominal terms, which represented a 22.6% decrease in peso terms compared to our total indebtedness, including accrued interest, of Ps.1,978.8 billion as of December 31, 2024. As of December 31, 2025, 38.4% of our existing debt, or Ps.588.7 billion (U.S.$32.8 billion), including accrued interest, is scheduled to mature in the next three years, including Ps.345.2 billion (U.S.$19.2 billion) scheduled to mature in 2026. Our working capital improved from a negative working capital of Ps.768.0 billion (U.S.$37.9 billion) as of December 31, 2024 to a negative working capital of Ps.530.5 billion (U.S.$29.5 billion) as of December 31, 2025. Our level of debt may increase further in the short or medium term as a result of new financing activities, which may adversely affect our financial condition or, in accounting terms, due to future depreciation of the peso against the U.S. dollar, which could further impact our financial condition, results of operations and liquidity positions. To service our debt, we have relied and may continue to rely on a combination of cash flows from our operations, drawdowns under our credit facilities, capital contributions from the Mexican Government and additional financing schemes (including refinancing of existing indebtedness).

During 2025, we received Ps.395.3 billion (U.S.$22.0 billion) in capital contributions from the Mexican Government to strengthen our financial position and for the "*Proyecto Aprovechamiento de Residuales*" (Waste Utilization Project) in the Salina Cruz and Miguel Hidalgo. These contributions represented an important source for the payment of our debt during 2025.

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

If we were unable to obtain financing on favorable terms or any terms at all, this could hamper our ability to invest in projects, replace hydrocarbon reserves, and meet our principal and interest payment obligations with our creditors. This risk would increase if support from the Mexican Government were to be discontinued or diminished. As a result, we may be exposed to significant liquidity constraints and may be unable to service our debt, pay our suppliers, or make the necessary capital expenditures to maintain our target production levels and to maintain, and increase, the proved hydrocarbon reserves assigned to us by the Mexican Government, which may adversely affect our financial condition and results of operations. See "—*Risk Factors Related to our Relationship with the Mexican Government—We must make significant capital expenditures to sustain our current production levels, and to maintain, as well as increase, the proved hydrocarbon reserves assigned to us by the Mexican Government. Reductions in our revenue, adjustments to our capital expenditures budget or an inability to obtain financing may limit our ability to make capital investments*" below.

If such constraints occur at a time when our cash flow from operations is insufficient to meet our debt service obligations, as was the case for the year ended December 31, 2025, we could be forced to further reduce our planned capital expenditures and implement further austerity measures in order to provide additional liquidity to our operations. A reduction in our capital expenditure program could adversely affect our financial condition and results of operations. Additionally, such measures may not be sufficient for us to meet our obligations.

***Our consolidated financial statements have been prepared on the assumption that we will continue as a going concern.***

Our consolidated financial statements as of December 31, 2025, have been prepared under the assumption that we will continue as a going concern. However, there is material uncertainty that raises significant doubt about our ability to continue operating as a going concern. Our consolidated financial statements as of December 31, 2025, do not include any adjustments that might result from the outcome of that uncertainty. If the actions we are taking to improve our financial condition, which are described in detail under "*Item 5— Overview — 2025-2035 Strategic Plan*" are not successful, we may not be able to continue operating as a going concern.

***Downgrades in our credit ratings could negatively impact our access to the financial markets and cost of financing.***

We rely on access to the financial markets to fund our operations and finance the capital expenditures needed to carry out our capital investment projects. Accordingly, credit ratings are important to our business and financial condition, as credit ratings affect the cost and other terms upon which we are able to obtain funding.

Ratings address our creditworthiness and the likelihood of timely payment of our long-term debt securities. Ratings are not a recommendation to purchase, hold or sell securities and may be changed, suspended or withdrawn at any time. Our current credit ratings and the rating outlooks depend, in part, on economic conditions and other exogenous factors that affect credit risk and are beyond our control, as well as assessments of the creditworthiness of Mexico.

Certain rating agencies downgraded Mexico's credit ratings in July 2022 and their assessment of Mexico's creditworthiness has affected and may further affect our credit ratings. Further, in July 2023 and February 2024, certain rating agencies downgraded our credit rating and ratings outlook. We currently have a "split rating" among the rating agencies that formally rate our credit profile. In 2025, two of the three rating agencies upgraded our credit rating due to the Mexican Government's increased commitment to supporting our financial obligations and the publication of our 2025-2035 Strategic Plan.

While ratings downgrades do not constitute a default or an event of default under our debt instruments, they can increase our cost of financing. Notwithstanding the recent upgrades to our credit ratings, there can be no assurance that such upgrades will be sustained, and future downgrades could occur as a result of factors beyond our control, including changes in the creditworthiness of Mexico or a deterioration in our financial condition. Any such downgrades could significantly harm our financial condition, results of operations and ability to meet existing obligations. In addition, for new financings or amendments to existing financing arrangements, more restrictive covenants, higher collateral requirements and other less favorable terms could reduce our financial and operational flexibility, negatively impact our liquidity and the prices of our debt securities, reduce our potential pool of investors and limit our funding sources, among other consequences. There can be no assurance that we will be able to maintain or improve our current credit ratings or outlook*.*

***Crude oil, natural gas and petroleum products prices are volatile, and low crude oil, natural gas and petroleum products prices adversely affect our income and cash flows and the value of the hydrocarbon reserves that we have the right to extract and sell.***

Most of our cash flow derives from sales of crude oil, petroleum products and natural gas. International prices of these products fluctuate due to global supply and demand dynamics, as well as many factors beyond our control. These factors include (i) competition within the oil and natural gas industry, (ii) the existence and development of alternative sources of energy, (iii) prices of alternative sources of energy, (iv) the cost of exploration and extraction of oil fields, (v) international economic trends, (vi) exchange rate fluctuations, (vii) expectations of inflation, (viii) domestic and foreign laws and government regulations, (ix) energy transition policies, (x) political, social and other events (including public health events and armed conflict) in major oil- and natural gas-producing and consuming nations, (xi) actions taken by Organization of the Petroleum Exporting Countries ("OPEC") members and other oil exporting countries, (xii) oil and natural gas trading activity and (xiii) transactions in derivative financial instruments ("DFIs") related to oil and gas.

If international prices of crude oil, petroleum products and/or natural gas decrease, we earn less revenue and less income before taxes, which generate lower cash flows and limits our ability to make capital expenditures and meet our financial obligations as our fixed costs remain roughly constant. Conversely, if prices of crude oil, petroleum products and/or natural gas increase, we may earn more revenue and our income before taxes and duties increases.

During 2025 and 2024, the weighted average Mexican crude oil price remained volatile due to market conditions, averaging U.S. $61.75 per barrel, and U.S. $70.20, respectively. As of the date of this annual report, crude oil prices continue to show high volatility, mainly due to armed conflict in the Middle East and related disruptions in international trade. See "*Risk Factors Related to Our Operations*—*Our business could be negatively impacted by hydrocarbon price volatility as the result of actual or threatened* global *military or paramilitary activity, political tensions, and any related destabilization of the world energy markets*" below.

Any future decline in international crude oil and natural gas prices will have a negative impact on our results of operations and financial condition. Price fluctuations may also affect estimates of the amount and value of Mexico's hydrocarbon reserves that we have the right to extract and sell, which could affect our future production levels. See "*—Risk Factors Related to our Relationship with the Mexican Government—Hydrocarbon reserves are based on estimates, which are uncertain and subject to revisions"* and "*Item 11—Quantitative and Qualitative Disclosures About Market Risk—Changes in Exposure to Main Risks—Market Risk—Hydrocarbon Price Risk*." below.

***Our business could be negatively impacted by hydrocarbon price volatility as a result of actual or threatened global military or paramilitary activity, political tensions, and any related destabilization of the world energy markets.***

Our income and cash flows depend on the prices of crude oil, petroleum products and natural gas. Oil prices are highly sensitive to real and perceived threats to global geopolitical stability, as well as to changes in production from OPEC and OPEC+ member states and other oil-producing nations, which can cause either oversupply or shortages in the market. Volatility in global oil, natural gas and petroleum products prices may increase as a result of international sanctions, trade restrictions and other governmental actions affecting crude oil supply in global markets. Such volatility may also result from actual or threatened military or paramilitary activities, including the ongoing war in Ukraine, hostilities involving Israel, Hamas, Hezbollah, the United States and Iran in the Middle East, disruptions affecting regional shipping lanes and other critical supply routes, and political, regulatory and sanctions-related developments affecting the energy sector.

These events, and the perception that they may intensify or expand, could cause sudden increases or decreases in the prices of crude oil, natural gas and petroleum products, disrupt production, transportation and export activities, impair access to significant transit routes, and increase overall market volatility. In particular, hostilities in the Middle East, including any actual or threatened disruption, closure or reduced access to the Strait of Hormuz or other significant supply routes, could materially disrupt regional and global energy markets. In addition, changes in sanctions regimes, governmental control, export policies or investment conditions in Venezuela or other significant oil-producing countries could alter regional and global supply dynamics. Any such changes could contribute to market instability and increase price volatility.

Any increase in oil, gas and petroleum products prices resulting from these conflicts or developments may be temporary and may be offset or reversed by factors beyond our control, including changes in global supply and demand, actions by OPEC and OPEC+ member states and other producing nations, sanctions relief, ceasefires, releases from strategic reserves or other geopolitical or macroeconomic developments. Conversely, any resulting decline in commodity

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

prices, sustained period of heightened volatility, or disruption to supply, transportation or market access could have a material adverse effect on our business, financial condition, results of operations and cash flows.

***Our business may be materially and adversely affected by the emergence of epidemics or pandemics.***

Public health events, including epidemics and pandemics caused by infectious agents and diseases, may adversely impact the health of our workforce, disrupt the operations of our partners and suppliers, and affect or change supply chains routines and procedures. Public health events can also compromise the operation of our key facilities, including our oil platforms, refineries and terminals, causing disruptions in our supply chain. In addition, public health events may impact the economy of Mexico, its population and/or the global economy, influencing the international prices of, and/or supply and demand for, crude oil, refined products and/or natural gas, which may in turn affect our business, results of operations and financial condition. The impact of current or future public health events is highly uncertain and will depend on numerous evolving factors that we cannot predict. See "—*Risk Factors Related to our Operations—Crude oil, natural gas and petroleum products prices are volatile, and low crude oil, natural gas and petroleum products prices adversely affect our income and cash flows and the value of the hydrocarbon reserves that we have the right to extract and sell*" above for further information.

***We are an integrated oil and gas company and are exposed to production, equipment and transportation risks, criminal acts, blockades to our facilities and deliberate acts of terror that could adversely affect our business, results of operations and financial condition.***

We are subject to several risks that are common among oil and gas companies. These risks include (i) production risks, including fluctuations in production due to operational hazards, accidents at our facilities and effects of natural disasters or weather, (ii) equipment risks, including those relating to the adequacy, condition and maintenance of our facilities and equipment and (iii) transportation risks, including those relating to the condition, availability and vulnerability of pipelines and other modes of transportation. Our business is subject to risks of explosions in pipelines, refineries, plants, drilling wells and other facilities, as well as oil spills, hurricanes in the Gulf of Mexico and other natural disasters, accidents, fires and mechanical failures.

Our operations are also exposed to risks arising from criminal acts to steal, divert or tamper with our crude oil, natural gas and refined products from our pipeline network, as well as materials and equipment theft. These acts include the illegal extraction of hydrocarbons, such as clandestine "tapping" of our pipelines. Such criminal activity has led to fires explosions, property and environmental damage, injuries and loss of life, as well as loss of revenue from stolen products. In addition, the illegal trade in hydrocarbons, including through counterfeit schemes that undervalue, mislabel and fail to quantify imported hydrocarbons for tax evasion purposes, disrupt the domestic fuels market, adversely affect our operating results and damage our reputation.

The measures we have taken in conjunction with the Mexican Government to reduce the illicit fuel market have not resulted in sustained improvement. In 2025 and 2024, we identified 10,591 and 11,774 illegal pipeline taps, respectively. We are also exposed to the risk that some of our employees or public officials may participate, or be perceived to participate in the illicit market in fuels. In addition, our facilities are exposed to intentional acts of sabotage, terrorism, blockades, theft and piracy. Incidents of this nature in connection with the production, processing and transportation of oil and gas products could result in personal injury, loss of life, environmental damage, related containment, cleanup and repair costs and damage to equipment and facilities, any of which could adversely affect our business, results of operations and financial condition.

***We are exposed to cybersecurity incidents and attacks that could materially adversely affect our business, results of operations and financial condition.***

Our operations rely on information technology and specialized systems. In recent years, cyber-threats and cyber-attacks targeting critical infrastructure in the energy sector have become more sophisticated, frequent, coordinated and costly, and could be and have been targeted at our operations or information technology systems. These attacks seek to exploit vulnerabilities in business and industrial systems and equipment, disrupting business continuity and compromising sensitive data. If the integrity of our information technology and specialized systems were to be materially compromised due to a cyber-attack or due to the negligence or misconduct of our employees, our business operations could be disrupted or even paralyzed, and our proprietary information could be stolen or lost. If such information security failures occur, we could experience, among other things: (i) disruptions in critical infrastructure operations affecting the production and distribution of hydrocarbons and derivatives, (ii) regulatory penalties, (iii) legal liability resulting from breaches of

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

personal, customer or partner data, (iv) reputational damage and loss of trust, (v) decreased revenues and financial losses due to business interruption, theft or alteration of information, depending on the magnitude of the incident; (vi) increased operational costs, including system recovery, enhanced security measures and compensation payouts and (vii) loss of strategic assets depending on the severity of incidents affecting critical systems, which in turn could have a material adverse effect on our results of operations and financial condition.

***A continued decline in our proved hydrocarbon reserves and production could adversely affect our operating results and financial condition.***

Some of our existing oil and gas-producing fields are mature and, as a result, our reserves and production may decline as reserves are depleted. In 2025, our total proven reserves had an increase of 21.3 million barrels of crude oil equivalent, or 0.3%, after accounting for discoveries, extensions, revisions, and delimitations, from 7,450.6 million barrels of crude oil equivalent as of December 31, 2024 to 7,471.9 million barrels of crude oil equivalent as of December 31, 2025. See "*Item 4—Information on the Company—Business Overview––Exploration and Extraction––Reserves*" for more information about the factors leading to this increase.

Based on these numbers, our reserve replacement ratio ("RRR") in 2025 was 102.6%, an increase as compared to a RRR of 96.6% in 2024. Our proven reserves increased from 7,450.6 million barrels of crude oil equivalent as of December 31, 2024 to 7,471.9 million barrels of crude oil equivalent as of December 31, 2025, due to discoveries, developments, delineations and revisions of our proved reserves, in particular to the recategorization of reserves as a result of production and pressure histories analysis in several reservoirs. Our crude oil production decreased by 7.0% in 2025, mainly due to the natural decline of some of our main fields such as Zaap, Quesqui, Tupilco Profundo, Xanab and Pokche, the lag in the installation of marine infrastructure, as well as unusual bad weather conditions that affected the continuity of offshore operations and delays in the completion times of wells with high complexity due to their depth, pressure and temperature conditions. There can be no assurances that we will be able to replace our proved reserves and prevent a decline in our production. Failing to replace our reserves could have an adverse effect on our production expectations and results of operations, increase our need for external financing and compromise our long-term financial conditions.

***Developments in the oil and gas industry and other factors may result in substantial write-downs of the carrying amount of certain of our assets, which could adversely affect our operating results and financial condition.***

We evaluate on an annual basis, or more frequently where the circumstances require, the carrying amount of our assets for possible impairment. Our asset 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.

Changes in the economic, regulatory, business or political environment in Mexico or in other markets where we operate—such as the liberalization of fuel prices, a significant decline in international crude oil and gas prices, regulatory changes and stricter environmental policies, among other factors— may result in the recognition of impairment charges in certain of our assets. Due to fluctuations in the price of crude oil and annual variations in discount rates, among other factors, we have performed impairment tests on our non-financial assets (other than inventories and deferred taxes) at the end of each quarter. As of December 31, 2025, 2024 and 2023 we recognized net impairments of Ps.8.1 billion, Ps.53.5 billion and Ps.28.8 billion, respectively. See Note 12 to our audited consolidated financial statements as of December 31, 2025 for further information about the impairment of certain of our assets. Future developments in the economic environment, in the oil and gas industry and other factors could result in further substantial impairment charges, adversely affecting our operating results and financial condition.

***Competition in the energy sector could adversely affect our business and financial performance.***

The Mexican Constitution and the *Ley del Sector Hidrocarburos* (the "Hydrocarbons Sector Law") allow other oil and gas companies to carry out certain activities related to the energy sector in Mexico, including exploration and extraction activities, and the import and sale of gasoline. Accordingly, we face competition for the right to explore and develop new oil and gas reserves. Additionally, we are likely to face competition in connection with certain refining, transportation and processing activities, and in the distribution and sale of gasoline and other fuels. The Hydrocarbons Sector Law gives us priority in various industry activities and currently limits participation of private companies in exploration and extraction activities in Mexico. A failure to compete effectively, or any increased competition in industry activities, including as a

------

result of modifications to the Hydrocarbons Sector Law, could have an adverse impact on our results of operations and financial condition and make it difficult for us to hire and retain skilled personnel.

***We are subject to Mexican and international anti-corruption, anti-bribery, anti-money laundering or similar laws. Our failure to comply with these laws could result in penalties, which could harm our reputation and have an adverse effect on our business, results of operations and financial condition.***

We are subject to Mexican and international anti-corruption, anti-bribery and anti-money laundering laws. See "*Item 4—Information on the Company—General Regulatory Framework*." We maintain a corporate compliance program that includes policies and processes intended to monitor compliance with these laws, such as our internal control system. Our internal control system aims to prevent operational risks, anticipate any weaknesses arising from our operations or internal control over financial reporting and promote information exchange and communication. However, we are subject to the risk that our management, employees, contractors or any person doing business with us may (i) engage in fraudulent activity, corruption, bribery or other improper conduct, (ii) circumvent or override our internal controls and procedures or (iii) misappropriate or manipulate our assets to our detriment. This risk is heightened because we have large number of complex and significant contracts with domestic and foreign third parties. Although we have systems and internal policies in place for identifying, monitoring and mitigating these risks, such systems and policies have failed in the past and may not be effective in the future. Further, we cannot ensure that these compliance policies and processes will prevent intentional, reckless or negligent acts committed by our management, employees, contractors or anyone doing business with us. Any failure—real or perceived—to comply with applicable governance or regulatory obligations by our management, employees, contractors or any person doing business with us could harm our reputation, limit our ability to obtain financing and otherwise have a material adverse effect on our business, financial condition and results of operations.

If we fail to comply with any applicable anti-corruption, anti-bribery, anti-money laundering or similar laws, we and our management, employees, contractors or any person doing business with us may be subject to criminal, administrative or civil penalties and other measures, which could in turn have material adverse effects on our reputation, business, financial condition and results of operations. Any investigation of potential violations of anti-corruption, anti-bribery, anti-money laundering or similar laws by governmental authorities in Mexico or other jurisdictions could result in an inability to prepare our consolidated financial statements in a timely manner and could adversely impact our reputation, limit our ability to access financial markets and adversely affect our ability to obtain contracts, assignments, permits and other government authorizations necessary to participate in our industry, which, in turn, could have adverse effects on our business, results of operations and financial condition.

***Our management has identified material weaknesses in our internal control over financial reporting for nine of the last eleven years and has concluded that our internal control over financial reporting was not effective at December 31, 2023, 2024 and 2025, which may have a material adverse effect on our results of operations and financial condition.***

Our management identified one material weakness in our internal control over financial reporting for 2023 related to our authorization process for manual journal entries in our financial recording systems and such material weakness remained unremedied during 2024 and 2025. For further information on the material weakness identified by our management for 2025, see "*Item 15––Controls and Procedures––Management's Annual Report on Internal Control over Financial Reporting*." In light of the identified material weakness, our management concluded that our internal control over financial reporting was not effective at December 31, 2025. Although we are developing several measures to remedy this material weakness, we cannot be certain that these measures will be successfully implemented or that there will be no other material weaknesses in our internal control over financial reporting in the future. In addition, our management identified material weaknesses in our internal control over financial reporting in connection with the preparation of our consolidated financial statements as of and for each of the years ended December 31, 2015, 2016, 2017, 2018, 2020, 2021, 2023 and 2024. In light of the identified material weaknesses, our management concluded that our internal control over financial reporting was not effective at December 31 of each of those years. We disclosed the circumstances giving rise to these material weaknesses—which were generally different from one year to the next—in our annual reports on Form 20-F corresponding to each of those years. As of the date of this annual report, we believe that each of these material weaknesses has been remediated, except for the 2023 material weakness for which we are in the process of implementing remedial actions. For more information on such actions, see "*Item 15––Controls and Procedures––Management's Annual Report on Internal Control over Financial Reporting*" below.

We cannot be certain that additional material weaknesses will not develop or be discovered in the future. There is also a risk that there could be accounting errors in our financial reporting. If our efforts to remediate any material weakness are unsuccessful, we may be unable to report our results of operations for future periods accurately and in a timely manner and

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

make our required filings with government authorities, including the SEC. Any of these occurrences could adversely affect our results of operations and financial condition.

***We participate in strategic alliances and other joint arrangements, which may not always perform as expected, could harm our reputation and could have an adverse effect on our business, results of operations and financial condition.***

We have not entered into any strategic alliances or other joint arrangements since 2018. However, we continue to participate in arrangements entered into before 2018 and have entered into *contratos de servicios integrales de exploración y extracción* (long-term service contracts for oil production, or "CSIEEs"). Pursuant to the Hydrocarbons Sector Law, we can also enter into *contratos mixtos* ("Mixed Agreements") with other market participants to complement our technical, operational and financial capabilities in exploration and extraction activities. Although these agreements are intended to reduce or reallocate risks in oil and gas exploration and extraction, refining, transportation and processing activities, our partners in such arrangements may, as a result of financial or other difficulties, be unable or unwilling to fulfill their financial or other obligations under our agreements, potentially undermining the viability of the relevant project. Moreover, in certain strategic alliances, our partners may act contrary to our policies or objectives, which could be to our overall detriment. If our strategic alliances and other joint arrangements do not perform as anticipated, our reputation may be harmed and our business, financial condition and results of operations could be adversely affected.

***Our brand and reputation are key assets, and our business may be materially affected by how we are perceived in the media and by investors and rating agencies.***

Our reputation is a key asset, and perceptions surrounding our commitment to and compliance with environmental, corporate governance and social goals could have a material impact on us, our ability to obtain financing and the value of our debt securities. We are exposed to significant publicity and constant informational requests due to our relationship with the Mexican Government and our role in the Mexican economy. Political and public sentiment regarding the Mexican Government, Mexico, the oil and gas industry and us has resulted and may result in adverse publicity affecting us, which may expose us to reputational harm, regardless of the accuracy of information being publicized. Our exposure to potentially negative publicity is heightened by social media and the increasing sophistication and availability of generative artificial intelligence, which can facilitate the creation of false or misleading information and increase the velocity with which such information is distributed. In addition to the general risk that negative publicity poses to us and our reputation, rating agencies and third party environmental, social and governance certification agencies may consider publicly available data and information as part of their analysis and methodology. Any such information that adversely affects our reputation could be considered in the assessments by these agencies, potentially leading to increased scrutiny by investors and regulators, which could limit our access to financial markets and increase our cost of financing. See *"—Risk Factors Related to Climate Issues—Deficient performance related to environmental, social and governance (ESG) criteria could have an adverse impact on our ability to access capital markets, increase the cost of financing, reduce insurance or increase the cost of insurance and negatively affect our reputation.*"

**Risk Factors Related to our Relationship with the Mexican Government**

***The Mexican Government controls us, could transfer or reorganize our assets, and/or may limit our ability to satisfy our external debt obligations.***

We are controlled by the Mexican Government and our annual budget may be adjusted by the Mexican Government in certain respects. Pursuant to the Energy Reform Decree, we were transformed from a productive state-owned company to a state-owned public company on November 1, 2024. See "*Special Note Regarding Mexican Energy Reform*." Additionally, the 2025 Petróleos Mexicanos Law established a special regime governing, among other things, our budget, debt levels, administrative liabilities, acquisitions, leases, services and public works. This special regime provides us with technical and managerial autonomy, separate legal personality and, subject to certain restrictions, with autonomy with respect to our budget. Nevertheless, the Mexican Government still controls us and, subject to the approval of the Chamber of Deputies, has the power to adjust our targeted net cash flow for the fiscal year based on our projected revenues and expenses, as well as our annual wage and salary expenditures.

Downward adjustments to our annual budget may hinder our ability to develop the reserves assigned to us by the Mexican Government, limit our ability to compete effectively with other oil and gas companies and adversely affect our ability to make payments on our outstanding indebtedness. See "*Item 4—General Regulatory Framework*" for more information about the Mexican Government's authority with respect to our budget. Despite being wholly owned by the Mexican Government and receiving financial contributions to address our debt, our financial obligations do not constitute

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

obligations of, and are not guaranteed by, the Mexican Government. See "*—Risk Factors Related to our Relationship with the Mexican Government—Our financial obligations are not guaranteed by the Mexican Government*" below.

The Mexican Government's agreements with international creditors may affect our external debt obligations. In certain past debt restructurings of the Mexican Government, our external indebtedness was treated on the same terms as the debt of the Mexican Government and other public-sector entities, and it may be treated on similar terms in any future debt restructuring. In addition, Mexico has entered into agreements with official bilateral creditors to reschedule public-sector external debt. The Mexican Government has not requested restructuring of bonds or debt owed to multilateral agencies.

If the Mexican Constitution and federal law were amended, the Mexican Government would have the power to reorganize our corporate structure, including a transfer of all, or a portion of, our assets to an entity not controlled, directly or indirectly, by the Mexican Government. See "*—Risk Factors Related to Mexico*" below.

***Our financial obligations are not guaranteed by the Mexican Government.***

Although we are wholly owned by the Mexican Government, our financial obligations do not constitute obligations of, and are not guaranteed by, the Mexican Government. Accordingly, the Mexican Government has no legal obligation to make principal or interest payments on our debt, nor would any such obligation arise if we were unable to service our financial obligations.

***The Mexican Government may cease to support us.***

The Mexican Government made capital contributions to us of Ps.395.3 billion (U.S.$22.0 billion) during 2025 to strengthen our financial position, to support our debt service obligations and for the "*Proyecto Aprovechamiento de Residuales*" (Waste Utilization Project) in the Salina Cruz and Miguel Hidalgo refineries. Given that the Mexican Government is not legally or contractually obligated to make such capital contributions to us or assist us in repaying our debt, such support may cease at any time. Any change in the Mexican Government's support of us, including as a result of liquidity constraints or a change in policy objectives, would have a material adverse effect on our financial condition and ability to repay our indebtedness, as well as on the market value of our debt securities.

***We pay significant taxes and duties to the Mexican Government, which may limit our capacity to expand our investment program or negatively impact our financial condition.***

We are required to make significant payments to the Mexican Government, including in the form of taxes and duties. For the year ended December 31, 2025, our total taxes and duties were Ps.201.6 billion, representing 13.2% of our sales revenues in the form of taxes and duties, which constituted a substantial portion of the Mexican Government's revenues. Although the Mexican Government has previously granted us tax reductions, there can be no assurance that we will not be required to pay a larger portion of our sales revenue to the Mexican Government in the future, nor that tax collection will be suspended. On December 19, 2024, the *Ley de Ingresos de la Federación para el Ejercicio Fiscal de 2025* (the "2025 Federal Revenue Law") was published in the Official Gazette of the Federation. The 2025 Federal Revenue Law introduced changes to our fiscal regime that remain current under the *Ley de Ingresos de la Federación para el Ejercicio Fiscal de 2026*, published on November 7, 2025, in the Official Gazette of the Federation (the "2026 Federal Revenue Law"). See "—*Risk Factors Related to our Relationship with* the Mexican Government. *Recent changes to our fiscal regime may impact our ability to report our results of operations for future periods accurately and in a timely manner*," "*Item 4—Information on the Company—History and Development—Recent Energy Reform—New Fiscal Regime*" and "*Item 4—Information on the Company—Taxes, Duties and Other Payments to the Mexican Government—Fiscal Regime for PEMEX*." We cannot provide any assurances that any future changes will be favorable to us. Any increase in the amount of payments we must make to the Mexican Government could limit our ability to make capital investments or expand our investment program and could have a negative adverse impact on our financial condition.

Pursuant to the 2025 Petróleos Mexicanos Law, we were transformed from a productive state-owned company to a state-owned public company. Under the 2014 Petróleos Mexicanos Law, we and our subsidiary entities were subject to a dividend policy that required us to pay a state dividend to the Mexican Government on an annual basis. The 2025 Petróleos Mexicanos Law, which repealed and replaced the 2014 Petróleos Mexicanos Law, does not include a state dividend provision. Accordingly, we are no longer subject to the state dividend requirement, and we did not pay a state dividend in 2025. However, we cannot provide any assurances that the 2025 Petróleos Mexicanos Law will not be amended such that we would be required to pay a dividend in the future. For more information, see *"Item 4—Information on the Company—Taxes, Duties and Other Payments to the Mexican Government—Fiscal Regime for PEMEX."*

***Recent changes to our fiscal regime may impact our ability to report our results of operations for future periods accurately and in a timely manner.***

The 2025 Federal Revenue Law introduced changes to our fiscal regime aiming to simplify the fiscal framework and reduce the number of taxes and duties to which we are subject. Effective January 1, 2025, the Mexican Government consolidated the Profit-Sharing Duty and other taxes and duties payable by us into a new *Derecho Petrolero Para el Bienestar* ("Welfare Oil Duty"). This duty is set at a general rate of 30% on oil and fuel production and 11.63% for non-associated gas. Additionally, as of January 1, 2025, Petróleos Mexicanos is no longer subject to income tax. These modifications were maintained for fiscal year 2026 under the 2026 Federal Revenue Law.

However, we cannot assure that changes in our fiscal regime will not affect our ability to report our results of operations accurately and timely or comply with filing requirements with governmental authorities, including the SEC. This could limit our access to financial markets and hinder our ability to secure contracts, assignments, permits and other governmental authorizations necessary for participation in the oil and natural gas industry, thereby adversely affecting our business, results of operations and financial condition. Furthermore, there can be no assurances that our fiscal regime will not be further modified by the Mexican Government in the future. For more information, see "*Item 4—Information on the Company—Taxes, Duties and Other Payments to the Mexican Government—Fiscal Regime for PEMEX.*"

***The Mexican Government could enter into agreements with other nations to limit production.***

Although Mexico is not a member of OPEC, from time to time it enters into agreements with OPEC and non-OPEC countries to reduce the global supply of crude oil. We do not control the Mexican Government's international affairs, and the Mexican Government could enter into further agreements with OPEC, OPEC+ or other countries to reduce our crude oil production or exports in the future. A reduction in our oil production or exports may have an adverse effect on our business, results of operations and financial condition. For more information, see "*Item 4—Trade Regulation, Export Agreements and Production Agreements*."

***The Mexican nation, not us, owns the hydrocarbon reserves located in Mexico, and our right to continue to extract these reserves is subject to the approval of the Ministry of Energy.***

The Mexican Constitution provides that the Mexican nation, not us, owns all petroleum and other hydrocarbon reserves located in Mexican territory. Article 27 of the Mexican Constitution provides that the Mexican Government will carry out exploration and production activities through agreements with third parties and through assignments to and agreements with us. We and other oil and gas companies are allowed to explore and extract the petroleum and other hydrocarbon reserves located in Mexico, subject to assignment of rights by the *Secretaría de Energía* (Ministry of Energy) and entry into agreements pursuant 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 any future potential bidding rounds for additional exploration and production rights in Mexico. For more information, see "—*Risk Factors Related to our Relationship with the Mexican Government—We must make significant capital expenditures to sustain our current production levels, and to maintain, as well as increase, the proved hydrocarbon reserves assigned to us by the Mexican Government. Reductions in our revenue, adjustments to our capital expenditures budget or an inability to obtain financing may limit our ability to make capital investments.*"

***Hydrocarbon reserves are based on estimates, which are uncertain and subject to revisions.***

The information on oil, gas and other reserves set forth in this annual report is based on estimates. Reserves valuation is a subjective process of estimating underground accumulations of crude oil and natural gas that cannot be measured in an exact manner. The accuracy of any reserves depends on the quality and reliability of available data, and the interpretation and subjective judgment of experts.

Additionally, estimates may be revised based on subsequent results of drilling, testing and production. These estimates are also subject to certain adjustments based on changes in variables, including crude oil prices. Therefore, proved reserves estimates may differ materially from the ultimately recoverable quantities of crude oil and natural gas.

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

Downward revisions in our reserve estimates could lead to lower future production, which could have an adverse effect on our results of operations and financial condition. See "—*Risk Factors Related to our Operations—Crude oil, natural gas and petroleum products prices are volatile, and low crude oil and natural gas prices adversely affect our income and cash flows and the value of the hydrocarbon reserves that we have the right to extract and sell*". We revise our hydrocarbon reserve estimates annually, which may result in material revisions to estimates contained in this annual report. Our ability to maintain our long-term growth objectives for oil and gas production depends on our ability to successfully develop our reserves, and failure to do so could prevent us from achieving our long-term goals for growth in production.

On December 20, 2024, the Mexican Government published the Organic Simplification Decree. As a result, the National Hydrocarbons Commission and the CRE were dissolved, and their regulatory functions were transferred to the Ministry of Energy. In accordance with the Organic Simplification Decree and the implementing Law of the National Energy Commission, a new deconcentrated body—the National Energy Commission—was created within the Ministry of Energy to assume the regulatory responsibilities previously held by the CRE and, in certain matters, the National Hydrocarbons Commission.

Legal acts issued by the National Hydrocarbons Commission and CRE prior to their dissolution remain valid and binding, and contracts, agreements and other legal instruments continue to be effective and enforceable by the government entities or bodies that assumed their relevant functions, including the National Energy Commission. However, future procedures for auditing or adjusting our hydrocarbon reserves remain uncertain and may be subject to change under the new regulatory framework. Any request to adjust or revise our hydrocarbon reserve estimates could impact our ability to prepare our consolidated financial statements in a timely manner, which could, in turn, adversely affect our access to financial markets and our ability to secure contracts, assignments, permits and other authorizations necessary to participate in the oil and gas industry. This could have a material adverse effect on our business, results of operations and financial condition.

We cannot assure you that our hydrocarbon reserve estimates will not be revised by the National Energy Commission or as a result of changes implemented under the Organic Simplification Decree and its related legislation, which may affect the reserve classification or revision process. For more information, see "*—Risk Factors Related to Mexico—The current Mexican Government has sufficient control in the Mexican Congress to implement constitutional reforms which, if effected, could have a material adverse impact on our business, financial position or operating results.*"

***We must make significant capital expenditures to sustain our current production levels, and to maintain, as well as increase the proved hydrocarbon reserves assigned to us by the Mexican Government. Reductions in our revenue, adjustments to our capital expenditures budget or an inability to obtain financing may limit our ability to make capital investments.***

Our ability to maintain or increase our crude oil production is highly dependent on our ability to successfully develop existing hydrocarbon reserves and, in the long term, on our ability to develop additional reserves. Therefore, we continually invest capital to enhance our hydrocarbon recovery factor and improve the reliability and productivity of our infrastructure.

The development of the reserves assigned to us by the Mexican Government requires significant capital investments and poses significant operational challenges. Our right to develop such reserves is conditioned upon adherence to our development plans, which are formulated based on our technical, financial and operational capabilities at the time such reserves were assigned. We cannot provide assurances that we will have or will be able to obtain the necessary resources or technical capacity at the required time to explore and extract the reserves that the Mexican Government assigned to us or the reserves that the Mexican Government may assign to us in the future. In the past, we have reduced our capital expenditures in response to declining oil prices. If we are unable to increase our capital expenditures, we may not be able to develop the reserves assigned to us in accordance with our exploration and development plans. Additionally, if we fail to adhere to development plans, we could lose the right to continue to extract such reserves, which could in turn adversely affect our operating results and financial condition.

Our ability to make capital expenditures is limited by the substantial duties and taxes that we pay to the Mexican Government, the ability of the Mexican Government to adjust certain aspects of our annual budget, fluctuations in our revenues related to volatile oil prices and any other constraints on our liquidity. Our ability to undertake the necessary capital investments to maintain current production levels depends on the availability of financing. For more information on the liquidity constraints we are exposed to, see "*—Risk Factors Related to our Operations—We have a substantial amount of indebtedness and other liabilities and are exposed to significant liquidity constraints, which could make it difficult for us to obtain financing on favorable terms and could adversely affect our financial condition, results of operations and ability* 

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

*to repay our debt and, ultimately, our ability to operate as a going concern without additional support from the Mexican Government, which we may not receive.*"

In addition, we have entered into strategic alliances and other joint arrangements with third parties in order to develop our reserves. If our partners were to default on their obligations to us, we may be unable to maintain production levels or extract from our reserves. We also cannot provide any assurances that these strategic alliances and other joint arrangements will be successful or reduce our capital commitments. For more information, see "*—Risk Factors Related to Our Operations—We participate in strategic alliances and other joint arrangements, which may not always perform as expected, and harm our reputation and could have an adverse effect on our business, results of operations and financial condition.*"

***The Mexican Government has historically imposed, and may in the future impose, price controls or other pricing measures in the domestic market on our products.***

The Mexican Government has from time to time imposed price controls and other pricing measures on the sale of natural gas, liquefied petroleum gas, gasoline, diesel, gas oil intended for domestic use, fuel oil and other products. As a result, we may not be able to fully pass through increases in costs or market prices to customers in the domestic market, which could adversely affect our margins, results of operations and cash flows.

In 2017, the Mexican Government began gradually removing price controls on gasoline and diesel as part of the liberalization of fuel prices in Mexico, and sales prices for gasoline and diesel are generally determined by market conditions. However, on February 27, 2025, the Mexican Government and numerous private gasoline retailers entered into an agreement establishing a maximum price of Ps.24.00 per liter of regular gasoline, which was renewed on March 11, 2026. The effects of that agreement, as well as any similar arrangements or other governmental actions affecting domestic fuel prices, could adversely affect our results of operations. We have no control over the Mexican Government's domestic pricing or energy policies, and it may in the future impose formal price controls or take other actions to influence domestic fuel prices. Any such measures could limit our ability to adjust prices in response to changes in costs, market conditions or international prices, which could adversely affect our business, financial condition, results of operations and cash flows.

***We may claim some immunities under the Foreign Sovereign Immunities Act and Mexican law, and your ability to sue or recover may be limited.***

We are a state-owned public company of the Mexican Government. Accordingly, you may not be able to obtain a judgment in a U.S. court against us unless such U.S. court determines that we are not entitled to sovereign immunity with respect to that action. Under certain circumstances, Mexican law may limit your ability to enforce judgments against us in Mexican courts. We do not know whether Mexican courts would enforce judgments of U.S. courts based on the civil liability provisions of U.S. federal securities laws. Therefore, even if you were able to obtain a U.S. judgment against us, you might not be able to obtain a judgment in Mexico that is based on such U.S. judgment. Moreover, you may not be able to enforce a judgment against our property in the United States except under the limited circumstances specified in the Foreign Sovereign Immunities Act of 1976, as amended. Finally, if you were to bring an action in Mexico seeking to enforce our obligations under any securities issued by us, satisfaction of such obligations may be made in pesos, pursuant to the laws of Mexico.

Our directors and officers, as well as some of the experts named in this annual report, reside outside the United States. Substantially all of our assets and those of most of our directors, officers and experts are located outside the United States. As a result, investors may not be able to effect service of process on our directors or officers or those experts within the United States.

**Risk Factors Related to Mexico**

***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 or other adverse developments in Mexico could adversely affect our business and financial condition. Such developments could also lead to increased volatility in exchange rates and financial markets, thereby restricting our ability to secure new financing on favorable terms or at all and service our debt. In the past, the Mexican Government has implemented budget cuts in response to declining international crude oil prices and global economic conditions, and it may reduce our budget in the future. Any such budget cuts could adversely affect the Mexican economy and, consequently, our results of operations, financial condition and ability to service our debt. See "*Risk Factors—Risk Factors Related to our Relationship with the Mexican Government—*

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

*The Mexican Government controls us, could transfer or reorganize our assets, and/or may limit our ability to satisfy our external debt obligations*".

Mexico has experienced periods of economic contraction or low growth, high inflation, elevated interest rates, currency devaluation and other economic challenges. These conditions may worsen or recur in the future and could adversely affect our financial condition, as well as our ability to service our debt, particularly in the absence of additional support from the Mexican Government. A deterioration in international financial or economic conditions, whether due to a slowdown or recessionary conditions affecting Mexico's trading partners, including the United States, or as a result a new financial crisis, could have adverse effects on the Mexican economy, the Mexican Government's ability to support us, our financial condition and our ability to service our debt.

***Economic and political developments in Mexico and the United States may adversely affect Mexican economic policy and, in turn, our operations.***

Economic conditions in Mexico are highly correlated with economic conditions in the United States due to geographic proximity and the high degree of economic interdependence between the two countries. Accordingly, political and policy developments in the United States, including changes in administrations and U.S. fiscal, foreign, immigration, border security and other policies, could continue to influence the exchange rate between the U.S. dollar and the Mexican peso, capital flows, investment levels and economic conditions in Mexico, which could adversely affect our business, results of operations and financial condition.

In addition, changes in U.S. policy reflecting a more protectionist approach, including tariffs, investment restrictions, sanctions and industrial policies, have increased uncertainty regarding U.S.-Mexico relations. For example, on January 29, 2026, President Trump signed an executive order authorizing additional tariffs on goods from any country that directly or indirectly sells or otherwise provides oil to Cuba. The effect of that executive order, and of any similar measures, on the Mexican economy and our results of operations remains uncertain. Any further deterioration in U.S.-Mexico relations could adversely affect economic conditions in Mexico, limit our access to international capital markets and increase volatility in the markets in which we operate.

We cannot assure you that political or economic developments in Mexico and the United States, over which we have no control, will not have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to service or repay our debt.

***Changes in global trade policy could adversely affect the Mexican economy and, in turn, our operations and financial condition.***

In 2025, our export sales to the United States amounted to Ps. 397.5 billion, which represented 26.0% of our total revenues and 73.9% of our export sales. Historically, exports of petrochemical products from Mexico to the United States benefited from zero tariffs under the North American Free Trade Agreement ("<u>NAFTA</u>"), subject to certain exceptions. NAFTA was replaced on July 1, 2020 by the United States-Mexico-Canada Agreement (the "<u>USMCA</u>"). Although petrochemical exports from Mexico to the United States generally remain exempt from tariffs under the USMCA, any change in trade relations among Mexico, the United States and Canada, whether as a result of the imposition of tariffs, the modification, renegotiation, non-renewal or termination of the USMCA, or otherwise, could adversely affect the industries in which we operate, require us to renegotiate commercial arrangements or cause us to lose business, which could materially and adversely affect our business, results of operations and financial condition.

Beginning in 2025, the U.S. government made significant changes to its international trade policy and, in some cases, expressed interest in renegotiating or potentially terminating existing trade arrangements. These measures included tariffs on certain goods and trading partners, including steel and aluminum, new baseline and so-called "reciprocal" tariffs applicable to many countries, and threatened or imposed tariffs on certain Mexican goods that do not satisfy USMCA requirements. Continuing into 2026, the U.S. government has maintained or modified a number of these tariff measures, while also indicating that additional tariffs may be imposed under alternative legal authorities. On February 20, 2026, the U.S. Supreme Court held that IEEPA does not authorize the reciprocal or drug-trafficking tariffs, but the effect of that ruling and the extent to which the U.S. government may seek to implement similar measures under other authorities remain uncertain.

The medium- and long-term direction of U.S. trade policy remains uncertain as of the date of this annual report. Any additional tariffs, trade barriers or other restrictions imposed on Mexican products, or any adverse outcome in the review, renegotiation or possible termination of the USMCA, could reduce the competitiveness of our products, disrupt supply chains and trade flows, increase costs and reduce demand for our products. Further disruptions to global trade,

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

increased bilateral or regional trade frictions, or any resulting downturn in Mexico, the United States or the global economy could adversely affect our business, financial condition, results of operations, cash flows and ability to service or repay our debt.

We cannot assure you that the USMCA review process will preserve the current terms of trade among Mexico, the United States and Canada, or that U.S.-Mexico trade relations will not deteriorate and result in the imposition of additional trade barriers affecting the products we produce and sell. The macroeconomic and trade environment in which we operate is beyond our control and may become less favorable in the future.

***Mexico has experienced a period of heightened criminal activity, which could affect our operations.***

For the past several years, Mexico has experienced a period of heightened criminal activity, primarily due to the activities of drug cartels and related criminal organizations. In addition, in recent periods, actions by the Mexican Government targeting organized crime have at times been followed by retaliatory violence, vandalism, road blockades and broader disruption of commercial and civilian activity. The growth of an illicit fuel market in Mexico has led to increased theft and illegal trading of the fuels we produce, as well as theft of our equipment and materials.

In response, the Mexican Government has implemented various security measures and has strengthened its military and police forces. We have also continued to adopt strategic measures to reduce theft and other criminal activities targeting our facilities and products. See "*Item 8—Financial Information—Legal Proceedings—Actions Against the Illicit Market in Fuels*." However, criminal activity remains prevalent in Mexico and is likely to persist. Criminal activities, along with the associated damage to human life and property, may disrupt operations, interrupt the supply and distribution of our products, lead to significant economic losses, and negatively impact our business continuity, financial condition and results of operations.

***Changes in Mexico's exchange control laws may hamper our ability to service our foreign currency debt.***

The Mexican Government does not restrict the ability of Mexican companies or individuals to convert pesos into other currencies. However, we and certain other Mexican Government entities are required to buy and sell our foreign currency with *Banco de México* (the "Mexican Central Bank") in accordance with its terms and conduct all foreign currency transactions in compliance with its regulations. We cannot provide assurances that the Mexican Government will maintain its current policies regarding the peso. The Mexican Government has imposed foreign exchange controls in the past and could do so again in the future. If imposed, Mexican Government policies preventing us from exchanging pesos into U.S. dollars could hamper our ability to service our debt, the majority of which is denominated in currencies other than pesos, and other foreign currency obligations.

***The current Mexican Government has sufficient control in the Mexican Congress to implement constitutional reforms which, if enacted, could have a material adverse impact on our business, financial position or operating results.***

The political coalition led by Mexico's National Regeneration Movement (*Movimiento Regeneración Nacional* or "Morena") party has sufficient control in the Mexican Congress and several state legislatures to implement significant reforms, including amendments to the Mexican Constitution. The 2024 Mexican federal election strengthened Morena's political position, as it won the presidency and obtained a qualified majority in the lower chamber of the Congress and the Senate. The current Congress assumed office on September 1, 2024 and the current president, Claudia Sheinbaum, assumed office on October 1, 2024.

The concentration of political power in Mexico and any changes in Mexican politics or the Mexican economy resulting therefrom could have a material adverse impact on our business, results of operations, financial condition and ability to service our debt obligations. We cannot predict the nature or viability of any future legal or constitutional reforms or when or how they might be implemented. We cannot provide any assurances that these changes will not adversely affect the Mexican economy or our business, financial condition, results of operations and, ultimately, our ability to pay our debt when due.

***Changes in U.S. policy toward international criminal organizations pose uncertainty for Mexican businesses.***

On January 20, 2025, the U.S. government issued an executive order instructing the U.S. Department of State to designate certain international cartels and transnational criminal organizations as Foreign Terrorist Organizations ("FTOs"). On February 20, 2025, the U.S. government designated eight such entities, including six Mexican cartels, as FTOs. These designations expand the tools available for U.S. authorities to prosecute members of FTOs or individuals or

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

entities alleged to have provided them "material support" and increases the risk of potential criminal and civil liability against such entities and any members thereof. The potential direct and indirect effects on U.S. and Mexican businesses remains uncertain. For more information on our anti-corruption policies, see "*"—Risks Related to Our Operations—We are subject to Mexican and international anti-corruption, anti-bribery, anti-money laundering or similar laws. Our failure to comply with these laws could result in penalties, which could harm our reputation and have an adverse effect on our business, results of operations and financial condition"* and "*Item 4—Information on the Company—General Regulatory Framework*."

**Risk Factors Related to Climate Issues**

***Environmental regulations, including those aimed at mitigating climate change, could result in material adverse effects on our results of operations.***

A wide range of general and industry-specific environmental laws and regulations apply to our operations in Mexico and certain of our assets in the United States. This regulatory framework is continuously evolving and has become increasingly strict and costly. Compliance with these regulations entails significant operational and capital expenditures and limits our ability to extract hydrocarbons, resulting in lower revenues. Failure to comply could result in substantial fines, operational restrictions, and adversely affect our profitability and financial performance. For an estimate of our accrued environmental liabilities, see "*Item 4—Information on the Company—Environmental Regulation—Environmental Liabilities*." In addition, noncompliance with applicable regulatory requirements or poor environmental performance may damage our reputation and may limit our ability to access financing on favorable terms or at all.

Global efforts aimed at reducing greenhouse gas emissions, decarbonizing the economy and limiting global warming have led to an increased regulatory and financial burden for companies in the energy sector. This could result in additional capital requirements over the medium- to long-term to execute projects included in transition plans, as well as economic losses arising from legal liabilities, trade restrictions or, ultimately, the mandatory shutdown of our facilities.

***We are exposed to severe natural and weather conditions, which may be exacerbated by climate change.***

Our facilities and operations are exposed to physical risks from extreme weather events, such as floods, hurricanes, wildfires and droughts, as well as long-term hazards such as sea level rise, changes in precipitation patterns and increases in global average temperatures. Climate change has intensified the frequency and severity of adverse weather conditions, which could cause severe damage to our key facilities, disrupt our operations, reduce our production capacity and increase operational and maintenance costs. Adapting and protecting our assets from these risks may increase our costs and expenses and, in turn, could adversely affect our financial condition, limit our ability to invest in strategic projects and accelerate the deterioration of our assets.

***Growing international concern over climate change could adversely impact the value of our assets, our strategies and our results of operations.***

In the context of the global transition to a low-carbon economy, we face growing regulatory and financial challenges. Climate change mitigation policies, such as carbon taxes, cap-and-trade schemes and new energy efficiency requirements, may increase our operational costs and adversely affect our financial condition.

International agreements, such as the Paris Agreement adopted by the Mexican Government, include commitments to reduce emissions and adapt to climate change, which could result in additional restrictions on the exploration, production, and refining of hydrocarbons. Measures taken in response to these commitments could increase our costs and expenses. Additionally, such measures may promote a shift in consumer demand from petroleum-based fuels toward lower-carbon alternatives, adversely affecting our operations, financial results and long-term viability. See "*Item 4—Environmental Regulation—Climate Change*" below for more information on the Mexican Government's current legal and regulatory framework to combat climate change.

Our failure to implement a successful energy transition plan may damage our reputation, increase regulatory scrutiny and reduce our ability to contract with third parties or obtain financing on favorable terms. In addition, global decarbonization could negatively impact our business due to technological changes, such as the proliferation of cheaper renewables, making oil-based energy comparatively less profitable. Other risks include increasing consumer pressure for sustainable products and potential market disruptions, such as sharp drops in hydrocarbon product prices. All of these factors may have an adverse effect on our business, results of operations and financial condition.

***Deficient performance related to environmental, social and governance (ESG) criteria may adversely impact our reputation and could make it difficult for us to access financing, increase the cost of financing, reduce insurance options or increase the cost of insurance and negatively affect our reputation.***

In recent years, our financial counterparties, including investors, lenders and insurance companies, have expressed interest in our performance regarding ESG criteria. ESG considerations encompass: (i) social challenges such as improving our practices regarding human rights, worker health and protection, fair employment practices and culture of gender equality; (ii) environmental challenges such as reducing our greenhouse gas and air pollutant emissions, improving our effluent treatment systems, hazardous waste management and complying with admissible water discharge parameters; and (iii) corporate governance practices to integrate senior management decision-making, risk management and internal control processes.

While regulatory approaches to ESG matters in the U.S. continue to evolve, including at the federal and state levels, requirements and expectations may become less uniform and more difficult to assess. Failure to adapt to or comply with applicable regulatory requirements, or to meet evolving investor, lender, insurer or other stakeholder expectations regarding ESG practices and disclosures, could harm our reputation, limit our access to capital or insurance, increase our financing or insurance costs, and adversely affect our results of operations and financial condition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In January 2025, the CNBV issued a circular amending the General Provisions applicable to securities issuers and other entities, which established the obligation to disclose financial information in accordance with the International Financial Reporting Standards on Sustainability (IFRS S1) and Climate (IFRS S2). As of the end of fiscal year 2025, we are required to submit a report to the BMV in accordance with these regulations. If we fail to comply with the aforementioned regulatory requirements, our reputation and ability to access the capital markets could be affected, which could increase our financing costs.

**Item 4.&nbsp;&nbsp;&nbsp;&nbsp;Information on the Company**

**HISTORY AND DEVELOPMENT** 

We are the largest company in Mexico in terms of revenue, according to the July 2025 edition of *Expansión* magazine. According to the November 18, 2025, issue of Energy Intelligence Top 100: Global NOC & IOC Rankings, we are the ninetieth largest oil and gas company in the world based on 2024 data, taking into account parameters such as oil reserves, natural gas reserves, oil production, natural gas production, refinery distillation capacity and refined product sales.

Our executive offices are located at Avenida Marina Nacional No. 329, Colonia Verónica Anzures, 11300, Alcaldía Miguel Hildalgo, Ciudad de México, México. Our telephone number is +52 (55) 9126-8700.

In March 1938, President Lázaro Cárdenas del Río nationalized the foreign-owned oil companies that were then operating in Mexico, and the Mexican Congress established Petróleos Mexicanos through the *Decreto que crea la Institución Petróleos Mexicanos* (Decree that creates the entity Petróleos Mexicanos), which was published in the Official Gazette of the Federation and took effect on July 20, 1938.

In July 1992, the *Ley Orgánica de Petróleos Mexicanos y Organismos Subsidiarios* (Organic Law of Petróleos Mexicanos and Subsidiary Entities) took effect and created *Pemex-Exploración y Producción* (Pemex-Exploration and Production), *Pemex-Refinación* (Pemex-Refining), *Pemex-Gas y Petroquímica Básica* (Pemex-Gas and Basic Petrochemicals) and *Pemex-Petroquímica* (Pemex-Petrochemicals) as decentralized public entities of the Mexican Government with the legal authority to own property and conduct business in their own names.

In December 2013, the Mexican Government amended Articles 25, 27 and 28 of the Mexican Constitution and published transitional articles setting forth the general framework for implementing a comprehensive reform of the Mexican energy sector. The implementing legislation was published in the Official Gazette of the Federation in August 2014 and, required our corporate reorganization. Accordingly, we were transformed from a decentralized public entity of the Mexican Government to a productive state-owned company in October 2014. Further, in 2015, we transformed our four subsidiary entities into two new productive state-owned subsidiaries—*Pemex Exploración y Producción* (Pemex Exploration and Production) and *Pemex Transformación Industrial* (Pemex Industrial Transformation)—and created five new productive state-owned subsidiaries—*Pemex Perforación y Servicios* (Pemex Drilling and Services), *Pemex Logística* 

(Pemex Logistics), *Pemex Cogeneración y Servicios* (Pemex Cogeneration and Services), *Pemex Fertilizantes* (Pemex Fertilizers) and *Pemex Etileno* (Pemex Ethylene).

In July 2018, we issued the *Declaratoria de Liquidación y Extinción de Pemex Cogeneración y Servicios* (Declaration of Liquidation and Extinction of Pemex Cogeneration and Services), which became effective on July 27, 2018. All of the assets, liabilities, rights and obligations of our subsidiaries Pemex Cogeneration and Services were assumed by, and transferred to, Pemex Industrial Transformation, which became the successor to Pemex Cogeneration and Services as a matter of Mexican law.

In June 2019, we issued the *Declaratoria de Extinción de Pemex Perforación y Servicios* (Declaration of Extinction of Pemex Drilling and Services) and the *Declaratoria de Extinción de Pemex Etileno* (Declaration of Extinction of Pemex Ethylene), both of which became effective on July 1, 2019. All of the assets, liabilities, rights and obligations of our subsidiaries, Pemex Drilling and Services and Pemex Ethylene, were assumed by and transferred to Pemex Exploration and Production and Pemex Industrial Transformation, respectively. As a matter of Mexican law, Pemex Exploration and Production and Pemex Industrial Transformation became the respective successors to Pemex Drilling and Services and Pemex Ethylene.

In January 2021, we issued the *Declaratoria de Extinción de Pemex Fertilizantes* (Declaration of Extinction of Pemex Fertilizers), which became effective on January 1, 2021. All of the assets, liabilities, rights and obligations of our subsidiary Pemex Fertilizers were assumed by, and transferred to, Pemex Industrial Transformation, which became the successor to Pemex Fertilizers as a matter of Mexican law.

**Recent Energy Reform** 

*Energy Reform Decree*

On October 31, 2024, amendments to Articles 25, 27 and 28 of the Mexican Constitution were signed into law by President Claudia Sheinbaum Pardo and published in the Official Gazette of the Federation as the Energy Reform Decree. The Energy Reform Decree took effect on November 1, 2024, and transformed the legal regime of Petróleos Mexicanos from a productive state-owned company to a public state-owned company of the Mexican Government. The Energy Reform Decree reaffirmed the Mexican nation's ownership of the hydrocarbons located Mexico's subsoil and included transitional articles setting forth the general framework and timeline for its implementation through the Secondary Legislation.

*Secondary Legislation*

On March 12, 2025, the Mexican Congress approved the Secondary Legislation, which was subsequently signed into law by President Claudia Sheinbaum Pardo and published in the Official Gazette of the Federation on March 18, 2025. The Secondary Legislation took effect on March 19, 2025, and includes six new laws, the following of which are the most relevant to our operations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Ley de la Empresa Pública del Estado, Petróleos Mexicanos* (2025 Petróleos Mexicanos Law);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Ley del Sector Hidrocarburos* (Hydrocarbons Sector Law); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Ley de la Comisión Nacional de Energía* (Law of the National Energy Commission).

The Secondary Legislation also includes amendments to the following laws:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Ley del Fondo Mexicano del Petróleo para la Estabilización y el Desarrollo* (Law of the Mexican Petroleum Fund for Stabilization and Development);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Ley de Ingresos sobre Hidrocarburos* (Hydrocarbons Revenue Law); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Ley Orgánica de la Administración Pública Federal* (Organic Law of the Federal Public Administration)

*New Legal Regime* 

The Secondary Legislation modifies our legal regime and contains important changes to the legal framework governing Mexico's energy regulators. We describe below the key features of the Energy Reform Decree and the Secondary Legislation that relate to our corporate structure and the hydrocarbons sector in Mexico.

*<u>2025 Petróleos Mexicanos Law</u>*

The 2025 Petróleos Mexicanos Law repeals and replaces the *Ley de Petróleos Mexicanos* (2014 Petróleos Mexicanos Law) that had been in effect since October 2014. The 2025 Petróleos Mexicanos Law regulates our organization, management, operation, monitoring, evaluation and accountability. Key changes include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Legal Nature and Corporate Purpose*: Pursuant to the Energy Reform Decree and the 2025 Petróleos Mexicanos Law, we were transformed from a productive state-owned company to a public state-owned company. We remain wholly owned by the Mexican Government and retain the purpose of conducting activities related to the exploration, extraction, import, export and transformation of hydrocarbons—including the storage, commercialization, transportation, distribution and sale of hydrocarbons and their derivatives—to preserve Mexico's energy sovereignty, security, sustainability, self-sufficiency. However, our purpose has been expanded to include the development of activities related to energy sources other those derived from hydrocarbons, which will facilitate our participation in other sectors of the Mexican energy industry, including biofuels, renewable energy and lithium.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Special Regime*: We are now sectorized under the Ministry of Energy, with technical, operational, and managerial autonomy, with a mission oriented toward the public and social interest. We retain the special regime provided for in the 2014 Petróleos Mexicanos Law, which governed our activities relating to our subsidiaries, affiliates, compensation, assets, administrative liabilities, budget, debt levels and sustainability. Further, our activities are recognized as non-monopolistic.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Corporate Governance*: Our Board of Directors has been reduced from ten to eight members and will be composed of: (i) the Secretary of Energy, (ii) the Secretary of Finance and Public Credit, (iii) the Secretary of the Environment and Natural Resources, (iv) the Secretary of Science, Humanities, Technology and Innovation, (v) the Chief Executive Officer of the Comisión Federal de Electricidad (Federal Electricity Commission) and (vi) three independent board members. The requirements for independent board members remain unchanged and candidates must be nominated by the President of Mexico and ratified by a two-thirds majority in the Mexican Senate. Our new board was installed on April 22, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Corporate Reorganization*: The 2025 Petróleos Mexicanos Law dissolved Pemex Exploration and Production, Pemex Industrial Transformation and Pemex Logistics effective as of March 19, 2025. All of the assets, liabilities, rights and obligations of the subsidiary entities were assumed by, and transferred to, us, and we became the successor of the subsidiary entities as a matter of Mexican law. On May 22, 2025, the Board of Directors of Petróleos Mexicanos approved the Estatuto Orgánico de Petróleos Mexicanos (the "New Organic Statute"), which was published in the Official Gazette of the Federation on May 30, 2025 and became effective on June 1, 2025. The New Organic Statute established the new corporate structure and organization of Petróleos Mexicanos, eliminating the prior strict legal separation among subsidiary entities in order to operate in a vertically integrated manner.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An amendment to such New Organic Statute was subsequently published in the Official Gazette of the Federation on September 12, 2025, which primarily consisted of organizational changes, including: (i) the reassignment of the *Subdirección de Salvaguardia Estratégica* (Strategic Safeguard Subdivision) and the *Gerencia de Control Interno Institucional* (Internal Control Management Department) to report directly to our Chief Executive Officer; and (ii) the transfer of the *Gerencia de Coordinación de Operaciones* (Operations Coordination Department) within the Exploration and Extraction business segment to its head office.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Contractual Regime*: Pursuant to the 2025 Petróleos Mexicanos Law, we may enter into Mixed Development Agreements with third parties to carry out hydrocarbon exploration and extraction activities, in accordance with the guidelines approved by its Board of Directors and only within the areas assigned for such purposes by the Ministry of Energy, pursuant to the provisions of the Hydrocarbons Sector Law.

*<u>Hydrocarbons Sector Law and the Law of the National Energy Commission</u>*

The Hydrocarbons Sector Law repealed and replaced the *Ley de Hidrocarburos* (Hydrocarbons Law) that had been in effect since October 2014. The Hydrocarbons Sector Law establishes the legal framework for the exploration and production of oil and gas through assignments and contracts. Key changes include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Priority for Petróleos Mexicanos*: The Hydrocarbons Sector Law prioritizes our participation in the domestic hydrocarbon sector and introduces new mechanisms for private sector involvement in upstream activities through Mixed Development Agreements and limited contract models. For midstream and downstream activities, including oil refining and natural gas processing, the law repeals our open access obligations in

transportation, storage, and distribution infrastructure and eliminates asymmetric regulation and first-hand sale rules.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Ministry of Energy as Energy Regulator*: Effective March 19, 2025, the Ministry of Energy is responsible for the regulation and planning of the hydrocarbons and electricity sectors in Mexico. The National Hydrocarbons Commission has been extinguished and part of its duties and powers have been assumed by the Ministry of Energy, which now acts as counterpart in exploration and extraction contracts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *New National Energy Commission*: Effective March 19, 2025, the independent Energy Regulatory Commission was extinguished and replaced with the new National Energy Commission, a deconcentrated regulatory entity sectorized to the Ministry of Energy. The National Energy Commission assumed certain of the powers and duties of the Energy Regulatory Commission and, in certain downstream activities, maters previously under the purview of the National Hydrocarbons Commission.

*New Fiscal Regime*

On November 7, 2025, the *Ley de Ingresos de la Federación para el Ejercicio Fiscal de 2026* (2026 Federal Revenue Law) was published in the Official Gazette of the Federation. The 2026 Federal Revenue Law maintains changes to the fiscal regime applicable to Petróleos Mexicanos established by the 2025 Federal Revenue Law aimed at simplifying its fiscal framework and reducing the number of taxes and duties to which it is subject. As of January 1, 2025, the Mexican Government has consolidated the *Derecho de Utilidad Compartida* (Profit-Sharing Duty), the *Derecho de Extracción de Hidrocarburos* (Hydrocarbon Extraction Duty) and the *Derecho de Exploración de Hidrocarburos* (Hydrocarbon Exploration Duty) payable by Petróleos Mexicanos into a new *Derecho Petrolero Para el Bienestar* (Welfare Oil Duty), which is set at a general rate of 30% on oil and fuel production and 11.63% for non-associated gas. Additionally, Petróleos Mexicanos is no longer subject to income taxes. The Hydrocarbons Revenue Law amends the Hydrocarbons Law to incorporate the Welfare Oil Duty, our new taxation regime. For more information, see "*Item 4—Information on the Company—Taxes, Duties and Other Payments to the Mexican Government—Fiscal Regime for PEMEX*" and Note 21 to our consolidated financial statements included herein.

**Corporate Structure** 

As of the date of this annual report, our subsidiary entities have been dissolved, and all of their assets, liabilities, rights, and obligations were assumed by and transferred to us. Prior to March 19, 2025, each subsidiary was a legal entity empowered to own property and carry on business in its own name and had technical and operational autonomy, subject to the central coordination and strategic direction of Petróleos Mexicanos.

As a result of the change in our legal nature to a state-owned public company pursuant to the Energy Reform Decree and the 2025 Petróleos Mexicanos Law, our corporate structure and operations were vertically integrated, eliminating the prior strict legal separation among subsidiary entities in order to operate more efficiently. Accordingly, we are now responsible for carrying out the strategic activities of exploration and extraction of hydrocarbons. We are also responsible for the other activities in the value chain, including the refining and transformation of hydrocarbons and their derivatives, and the import, export, storage, commercialization, formulation, transportation, distribution and sale of hydrocarbons, petroleum products and petrochemicals. This integration enables PEMEX to conduct its corporate purpose in an integrated manner across its production processes and business lines.

In accordance with our New Organic Statute, our operations are organized through the following operating directorates (*direcciones operativas*):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Exploration and Extraction (Dirección de Exploración y Extracción): responsible for (i) identifying, discovering, evaluating, and extracting crude oil and natural gas reserves and (ii) drilling and production operations, reservoir stimulation, improved recovery techniques, and the initial conditioning and separation of hydrocarbons at the production site;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Industrial Processes (Dirección de Procesos Industriales): responsible for (i) overseeing the refining and manufacturing of petroleum products and petrochemicals and (ii) managing industrial operations including supply chain coordination, processing optimization, maintenance programs, energy management, and health, safety, and environmental performance across our refining and petrochemical facilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Energy Transformation (Dirección de Transformación Energética): responsible for (i) operating gas processing complexes and managing energy efficiency and transition projects, (ii) electricity generation and cogeneration

activities and (iii) driving operational performance improvements and sustainability objectives across our energy transformation infrastructure;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Logistics (Dirección de Logística): responsible for (i) managing the transportation, storage, and dispatch of hydrocarbons from producing areas to delivery points, (ii) operating pipeline, marine, and land transportation systems and (iii) maintaining measurement infrastructure while ensuring service quality and compliance with applicable regulatory requirements; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Commercialization (Dirección de Comercialización): responsible for (i) offering and selling hydrocarbons, refined products, and petrochemicals in Mexico and (ii) providing value-added services to permit-holders and end users across domestic markets.

Notwithstanding the organizational structure described above, Article 103 of the 2025 Petróleos Mexicanos Law requires us to maintain integrated accounting by segments within the entity, in order to provide consistency in our financial information. Accordingly, for accounting and financial reporting purposes, our operations are presented through six business segments: Exploration and Extraction, Industrial Processes, Energy Transformation, Deer Park Refining Limited Partnership (DPRLP), the Trading Companies and Other Operating Subsidiary Companies. The activities of our Logistics directorate are reflected within the Other Operating Subsidiary Companies segment. The activities of our Commercialization directorate are reflected across the producing segments (Exploration and Extraction, Industrial Processes and Energy Transformation), depending on which segment produces the hydrocarbons, refined products or petrochemicals being commercialized, while international trading activities are captured within the Trading Companies segment. For a description of each business segment and the financial information relating thereto, see Note 6 to our consolidated financial statements included herein.

**Capital Expenditures**

Our capital expenditures for 2025 were Ps.139,934 million, and we have budgeted Ps.132,007 million for capital expenditures in 2026. Both figures exclude amounts for non-capitalizable maintenance. The amount of our aggregate capital expenditures commitments for 2026 remains subject to adjustment by the Mexican Government. See "*Item 3—Key Information—Risk Factors—Risk Factors Related to our Relationship with the Mexican Government—The Mexican Government controls us, could transfer or reorganize our assets, and/or may otherwise limit our ability to satisfy our external debt obligations*." For capital expenditures planning and budgeting purposes, we organize our operations into business lines that differ from the reporting segments described above and in Note 6 to our consolidated financial statements. Our business lines reflect the operational structure through which we manage capital expenditure commitments and the execution of our investment program.

The following table sets forth our total capital expenditures, excluding non-capitalizable maintenance, by business line for the year ended December 31, 2025 and the budget for these expenditures for 2026. Capital expenditure amounts are derived from our budgetary records, which are prepared on a cash basis. Accordingly, these capital expenditure amounts do not correspond to capital expenditure amounts included in our consolidated financial statements prepared in accordance with IFRS. As a result of the corporate reorganization effective March 19, 2025, the business lines presented below reflect our new organizational structure and differ from those reported in our annual report on Form 20-F for the year ended December 31, 2024. A reclassification of 2024 and 2023 capital expenditures to conform to our current business line structure was not practicable because the prior organizational structure did not track financial information on the basis of our current business lines. For more information, see "*Special Note Regarding Mexican Energy Reform," "Item 4—Information on the Company—History and Development—Recent Energy Reform"* and Notes 1 and 6 to our consolidated financial statements included herein.

*Capital Expenditures Budget*

Our amended budget for 2026 totals Ps.570.9 billion, including operational expenses, assumes an average Mexican crude oil export price of U.S.$54.90 per barrel. Our 2026 budget contemplates a financial balance of Ps.263.5 billion for 2026, including a capital contribution from the Mexican Government of Ps. 263.5 billion for debt amortization. Our management expects that we will be able to maintain our medium- and long-term growth plans, without the need to incur indebtedness beyond the amount included in our approved financing program for 2026 of Ps. 261.6 billion because our financial balance projections consider additional actions, such as implementation of optimization measures and further investment in projects that we expect will contribute to the generation of increased revenues. Our budget was based on the guiding principles of (i) maintaining the industrial safety and reliability of our facilities; (ii) consolidating the stabilization of crude oil and gas production levels, increasing these production levels towards the end of the year and sustaining such growth in the medium and long term; (iii) increasing the crude processing capacity in the Sistema Nacional de Refinación (National Refining System); (iv) increasing the recovery factor of high value-added petroleum products; and (v) meeting our labor and financial obligations.

On February 27, 2026, the administration authorized an amendment to our original 2026 budget, which considers a total investment budget of Ps.303.3 billion for capital expenditures. Our amended budget for 2026 includes Ps.120.1 billion for non-capitalizable maintenance and Ps. 11.9 billion for financial investment as capital contributions, which determines a capital expenditures budget of Ps.132.0 billion.

We expect to allocate Ps.86.7 billion (or 65.7%) of such budget to exploration and extraction programs and Ps.29.8 billion (or 22.6%) to our Industrial Processes segment. We continuously review our capital expenditures portfolio in accordance with our current and future business plans, as well as business opportunities.

Our main objectives for upstream investment are to maximize our long-term economic value, increase and improve the quality of the oil and gas reserves assigned to us, enhance our reserves recovery ratio, improve the reliability of its production and transportation infrastructure for crude oil and natural gas operations and continue emphasizing industrial safety and compliance with environmental regulations. Our amended 2026 budget objectives include maintaining crude oil production at levels sufficient to satisfy domestic demand and have a surplus available for export and maintaining natural gas production levels.

Our downstream investment program seeks to increase our refining capacity, improve the quality of our product selection and the reliability of our logistics and distribution services, achieve a level of efficiency comparable to that of our international competitors and continue emphasizing industrial safety and environmental compliance.

Capital expenditures and budget by project, excluding non-capitalized maintenance are described under each segment below in this Item 4.

**BUSINESS OVERVIEW**

**Overview by Business Segment**

*Exploration and Extraction (formerly Pemex Exploration and Production)*

Prior to March 19, 2025, our exploration and extraction activities were conducted by the former productive state-owned subsidiary Pemex Exploration and Production. Effective March 19, 2025, Pemex Exploration and Production has been dissolved and all of the assets, liabilities, rights and obligations of Pemex Exploration and Production have been assumed by us. Further, all operations of Pemex Exploration and Production are now conducted by us through our Exploration and Extraction segment. For more information, see "*Special Note Regarding Mexican Energy Reform" and "Item 4—Information on the Company—History and Development—Recent Energy Reform*.*"* For 2025, there were no changes in the reporting of our Exploration and Extraction segment.

Our Exploration and Extraction segment explores for and extracts crude oil and natural gas, primarily in the northeastern and southeastern regions of Mexico and offshore in the Gulf of Mexico. In nominal peso terms, our capital expenditures in exploration and extraction activities decreased by 41.7% in 2025 due to a reallocation of resources dedicated to capital expenditures. As a result of these investments, our total hydrocarbon production reached a level of 856.3 million barrels of oil equivalent in 2025. Further, our crude oil production decreased by 7.0% from 2024 to 2025, averaging 1,618.5 thousand barrels per day in 2025, mainly due to a decline in production at some of our main fields, including Zaap, Quesqui, Tupilco Profundo, Xanab and Pokche. This decline in production levels was due to bad weather conditions affecting the continuity of offshore operations and delays in the completion of wells with high complexity due to their depth, pressure and temperature conditions.

Our natural gas production (excluding natural gas liquids) increased 1.0% from 2024 to 2025, averaging 4,556.1 million cubic feet per day in 2025. This increase was primarily due to the development of the Bakte field. Our main sources of natural gas production are the Akal, Maloob, Zaap, Koban, Ku, Onel, and May offshore fields and the Ixachi, Quesqui, Bakte, Teotleco, Racemosa and Tupilco Profundo onshore field projects. Exploration drilling activity decreased by 45.5% from 2024 to 2025, from 33 exploratory wells completed in 2024 to 18 exploratory wells completed in 2025. Development drilling activity decreased by 42.9% from 2024 to 2025, from 105 development wells completed in 2024 to 60 development wells completed in 2025. In 2025, we completed the drilling of 78 wells in total. In 2025, our exploration drilling activity was focused on the shallow waters of the Gulf of Mexico and onshore regions, and our development drilling activity was focused on increasing the production of crude oil and associated gas at offshore field Maloob and onshore fields Ixachi, Bakte, Remolino and Eltreinta.

In 2025, we invested in five new developments in onshore fields. We also continued developing 18 of 20 fields that have been under development since 2019, resulting in a total of 23 developments (10 in shallow water and 13 in onshore fields). As of December 31, 2025, 22 of these 23 fields were productive: nine in shallow water and thirteen in onshore fields. These 22 fields had an average monthly production of 246 thousand barrels per day of crude oil and 1,254 million cubic feet per day of natural gas by December 2025.

Our primary objectives for 2026 include: i) incorporating hydrocarbon reserves to contribute to the restoration of production; and ii) strengthening and optimizing Exploration and Extraction projects and assignments based on the efficient use of resources and oriented towards the development of productive projects. These objectives are expected to be achieved through the following strategies: 1) strengthening the portfolio of exploration opportunities in established and hypothetical plays, 2) improving the efficiency of exploration activity in onshore basins, shallow waters and frontier areas, 3) providing certainty to discovered hydrocarbon reserves, 4) mitigating the decline in production from fields, 5) consolidating the implementation of secondary and enhanced recovery processes, 6) developing new fields, 7) increasing the production of non-associated gas, 8) designing and implementing business schemes to attract private investment and 9) consolidating the reliability and operational efficiency of facilities.

Entering 2026, our production goals include producing crude oil at a level of approximately 1,656.7 thousand barrels per day and maintaining natural gas production above 5,001.0 million cubic feet per day. We aim to meet these production goals through (a) exploration and development activities, (b) increasing inventory reserves through new discoveries and reclassifications and (c) managing the decline in field production by focusing our exploration and production activities in areas where we have greater experience and higher historical success rates, such as secondary and tertiary recovery systems. In addition, we intend to reallocate resources away from deep-water projects, which tend to be expensive and long-term activities, and towards shallow water and onshore projects, which have the potential for near-term results. In 2026, we plan to incorporate one new development in an offshore shallow water field. We will continue with the development of 18 of 23 fields that we have been developing since 2019, resulting in a total of 19 developments, 10 in

------

shallow water and 9 in onshore fields. We expect that 18 of these 19 fields will have an average monthly production of 130 thousand barrels per day of crude oil and 574 million cubic feet per day of natural gas by December 2026.

*Industrial Processes and Energy Transformation (formerly Pemex Industrial Transformation)*

As of December 31, 2024, the industrial transformation segment operated through its productive state-owned subsidiary Pemex Industrial Transformation. Effective March 19, 2025, Pemex Industrial Transformation has been dissolved and all of the assets, liabilities, rights and obligations of Pemex Industrial Transformation have been assumed by Petróleos Mexicanos, however operations are now conducted through the Industrial Processes and Energy Transformation segments. For more information, see "*Special Note Regarding Mexican Energy Reform" and "Item 4—Information on the Company—History and Development—Recent Energy Reform and Note 1 to our consolidated financial statements incorporated in Item 18* ". As a result of this change, the financial information that was previously reported for Pemex Industrial Transformation is now reported under our Industrial Processes and Energy Transformation segments.

<u>Industrial Processes</u>

Our Industrial Processes segment generates revenue from the sale of refined petroleum products and their derivatives, most of which are sold to third parties in the domestic market. This market also supplies the CFE with a significant portion of its fuel oil for electricity production and provides jet fuel to Airports and Auxiliary Services, a state-owned administrator of airport services in Mexico. The most important refined products are gasoline, diesel and jet fuel.

<u>Energy Transformation</u>

Energy Transformation generates revenue from domestic sources primarily through the sale of natural gas, liquefied petroleum gas, naphtas, butane, ethane as well as certain other petrochemicals such as methane derivatives, ethane derivatives, aromatics, ammonia, fertilizers, and their derivatives.

The Industrial Processes segment's main activities are (i) refining processes and (ii) the production of petrochemicals (including ethylene and its derivatives, fertilizers and ammonia, aromatics and methanol), while the Energy Transformation segment is responsible for the processing of natural gas and the production of natural gas liquids and certain associated petrochemicals.

The Industrial Processes and Energy Transformation segments are further divided into six principal business lines: (i) refining, (ii) ethylene and derivatives, (iii) ammonia (formerly fertilizers), (iv) aromatics and derivatives, (v) methanol and petrochemical specialties, and (vi) gas.

***Refining and Petrochemicals (including Aromatics and Derivatives; and Methanol)***

In 2025, crude oil processing of the National Refining System was 108.2 thousand barrels per day higher than in 2024, representing an increase of 11.9%, from 905.6 thousand barrels per day in 2024 to 1,013.8 thousand barrels per day in 2025, as a result of the strategy implemented by Pemex to strengthen and consolidate the operational continuity of the country's refineries.

In 2025, production of refined products reached 1,022.1 thousand barrels per day, an increase of 11.9% compared to 913.7 thousand barrels per day in 2024. In addition to petroleum products, the oil refining process also produces propylene, carbon black raw material, sulfur, and carbon dioxide. In 2025, production of these petrochemical products was 12.4 thousand barrels per day, 4.7 thousand barrels per day higher than in 2024.

In 2025, the aromatics and derivatives line recorded production of 666.7 thousand tons, an increase of 75.0 thousand tons, or 12.7%, compared to the 591.7 thousand tons recorded in 2024, due to the reliability of the unit and its main services at the continuous catalytic reforming (CCR) unit of the Cangrejera Petrochemical Complex.

Methanol production at the Independencia petrochemical complex reached 139.4 thousand tons in 2025, representing a 12.6% increase from the 123.8 thousand tons produced in 2024, due to the continued operation of Methanol Plant No. 2 at the complex. Similarly, production of specialty petrochemicals was 6.3% higher, reaching 3.4 thousand tons in 2025.

***Ethlyene and Derivatives; Ammonia***

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

The ethylene and derivatives production line produces various petrochemical products, including ethane derivatives, propylene and its derivatives, and other products, including, but not limited to, oxygen, nitrogen, hydrogen and butadiene.

In 2025, the total production of our Ethylene and Derivatives business line decreased by 12.2%, as compared to 2024, from 600.9 thousand tons in 2024 to 527.8 thousand tons in 2025. This decrease was primarily due to lower availability of ethane.

Our main objective for the Ethylene and Derivatives business line in 2026 is to increase the reliability and operational efficiency of the ethylene derivatives facilities, by carrying out renovations at the main processing and service units at the Cangrejera and Morelos petrochemical complexes.

Ammonia production increased by 1.7% from 209.2 thousand tons in 2024 to 212.8 thousand tons in 2025. Meanwhile, carbon dioxide production increased by 4.9% from 512.1 thousand tons in 2024 to 537.4 thousand tons in 2025. In 2025, total production of methane derivatives reached 750.2 thousand tons, an increase of 4.0% compared to 2024 of 721.3 thousand tons.

Our strategy for the Ammonia business line in 2026 is focused on increasing production through the rehabilitation and consolidation of the reliability of the ammonia VI and VII units.

***Gas***

Our Gas business line is part of our Energy Transformation segment and comprises eight gas processing complexes, namely: Cactus, Nuevo Pemex, Ciudad Pemex, Poza Rica, Burgos, La Venta, Matapionche, and Arenque, plus the Coatzacoalcos Gas Processor Complex operated by our Industrial Processes segment.

Our Energy Transformation segment processes wet natural gas to obtain dry natural gas, ethane, liquefied petroleum gas (LPG) and other natural gas liquids. In 2025, our total sour natural gas processing capacity remained flat at 4,283.0 million cubic feet per day in our gas processing complexes.

In 2025, our Energy Transformation segment processed 2,144.9 million cubic feet per day of wet natural gas, of which 1,916.6 million cubic feet per day were sour wet gas and 228.4 million cubic feet per day were sweet wet gas. This figure represents a 7.5% decrease from the 2,318.9 million cubic feet per day we processed in 2024. This decrease was due to a lower availability of wet natural gas from the Exploration and Extraction segment.

In 2025, we produced 126.5 thousand barrels per day of natural gas liquids, a 16.6% decrease compared to 151.6 thousand barrels produced per day in 2024. This decrease was due to lower availability of wet gas from the Exploration and Extraction segment.

In 2025, we produced 1,721.4 million cubic feet per day of dry gas (natural gas with a methane content exceeding 90.0%), a decrease of 6.1% compared to 1,832.6 million cubic feet per day produced in 2024. This decrease was due to the reduction in wet gas production by the Exploration and Extraction segment.

Our strategy for the Gas business line in 2026 is to address critical risks in the production stages of the gas processing complexes, prioritizing maintenance and rehabilitation efforts to restore dry gas production, enhancing liquefiable products recovery, and boosting LPG, ethane and natural gasoline production.

*Logistics Operations (formerly Pemex Logistics)* 

Prior to March 19, 2025, our Logistics segment operated through the productive state-owned subsidiary Pemex Logistics and provided land, maritime and pipeline transportation, as well as storage and distribution services, to certain of our subsidiaries, local gas stations and distributors. Effective March 19, 2025 in connection with the enactment of the 2025 Petróleos Mexicanos Law, Pemex Logistics has been dissolved and all of its assets, liabilities, rights and obligations were assumed by Petróleos Mexicanos. Pursuant to our New Organic Statute, logistics activities are now conducted through our Logistics Operations business line as part of our Other Operating Subsidiary Companies segment. For more information, see "*Special Note Regarding Mexican Energy Reform" and "Item 4—Information on the Company—History and Development—Recent Energy Reform".*

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

During 2025, we injected 1,535.6 thousand barrels per day of crude oil and petroleum products into our pipelines, representing a 7.9% decrease as compared to 2024, when we injected 1,667.0 thousand barrels per day, primarily due to a decrease in crude oil processing at the Madero, Minatitlán and Salamanca refineries.

During 2025, we injected 114.9 thousand barrels per day of LPG, representing an 11.6% decrease as compared to the 130.0 thousand barrels per day of LPG injected in 2024, primarily due to lower transportation and delivery requirements in our Industrial Processes segment at terminals and interconnections associated with the LPG pipeline transportation system. Additionally, we injected 5.0 thousand barrels per day of petrochemicals in 2025, an increase of 117.4% as compared to the 2.3 thousand barrels per day we injected in 2024. This increase was mainly driven by higher demand for isobutane at the Minatitlán and Salina Cruz refineries.

In 2025, we transported a total of 2,350.9 thousand barrels per day of petroleum products: of which 1,655.5 thousand barrels per day (70.4%) were transported through pipeline systems, 454.7 thousand barrels per day (19.4%) were transported by land (381.5 thousand barrels per day by tank truck and 73.2 thousand barrels per day by tank car) and the remaining 240.7 thousand barrels per day (10.2%) were transported by tankers.

*International Trading* 

The international trading segment provides us with international trading, distribution, risk management, insurance and transportation services. This segment operates through P.M.I. Comercio Internacional, S.A. de C.V. (which we refer to as PMI), P.M.I. Trading DAC, (which we refer to as P.M.I. Trading), P.M.I. Norteamérica, S.A. de C.V., (which we refer to as PMI-NASA, and, together with PMI and P.M.I. Trading, we collectively refer to as the PMI Subsidiaries) and Mex Gas International, S.L. (which, together with the PMI Subsidiaries, we collectively refer to as the Trading Companies). Certain of the Trading Companies sell, buy and transport crude oil, refined products and petrochemicals in world markets, and provide related risk management, insurance, transportation and storage services. The Trading Companies have offices in Mexico City, Houston and Singapore. Export sales are made through PMI to major customers in various foreign markets.

In 2025, our crude oil exports decreased in volume by 28.0%, from 806.2 thousand barrels per day in 2024 to 580.6 thousand barrels per day in 2025. Natural gas imports increased by 14.3% in 2025, from 737.7 million cubic feet per day in 2024 to 843.1 million cubic feet per day in 2025. Petrochemical products exports decreased by 40.2%, from 17.9 metric tons in 2024 to 10.7 metric tons in 2025. Petrochemical product imports decreased by 27.8% in 2025, from 145.7 thousand metric tons in 2024 to 105.2 thousand metric tons in 2025. Our international trading segment's crude oil exports amounted to U.S.$13.0 billion in 2025, a decrease of U.S.$7.9 billion with respect to 2024 which amounted U.S.$20.9 billion.

**Exploration and Extraction (formerly Pemex Exploration and Production)**

*Exploration and Drilling* 

We seek to identify new oil reservoirs through our exploration program in order to increase the future replacement rate of proved reserves. From 1990 to 2025, we completed 14,768 exploration and development wells. During 2025, our average success rate for exploratory wells was 38.9%, an increase of 8.6 percentage points as compared to a success rate of 30.3% in 2024. Our average success rate for development wells was 91.7%, a decrease of 0.7 percentage points as compared to 92.4% for 2024. We discovered two new fields during 2025 (Konen and Iklum) and confirmed the extension of an existing field (Bakte) due to an appraisal well that was determined to be viable, bringing the total number of our producing fields to 355.

Our 2025 exploration program was comprised of exploration in both the onshore and the offshore regions of the Gulf of Mexico. Our exploratory activities yielded 12.2 million barrels of oil equivalent of proved reserves resulting from the discovery of the two oil-producing fields and the extension of an existing field.

The following table summarizes our drilling activity for the five years ended December 31, 2025, all of which occurred in Mexican territory.

*Extensions and Discoveries* 

During 2025, our exploration activity in the shallow waters of the Gulf of Mexico and onshore regions resulted in the discovery of two new hydrocarbon fields (Konen and Iklum) and confirmed the extension of an existing field (Bakte) due to an appraisal well that was determined to be viable. Together, these discoveries amounted to 12.2 million barrels of oil equivalent of proved reserves.

*Reserves* 

Under the Mexican Constitution, all oil and other hydrocarbon reserves located in Mexican territory are owned by the Mexican nation and not by us. As of December 31, 2025, Petróleos Mexicanos had the right to extract, but did not own, the reserves granted to us by the Mexican Government and to sell the resulting production. As of the date of this annual report, the exploration and development activities of Petróleos Mexicanos are limited to reserves located in Mexico.

Proved oil and natural gas reserves are those estimated quantities of crude oil, natural gas and natural gas liquids which geological and engineering data demonstrate 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.

Proved reserves estimates as of December 31, 2025 were prepared by our Exploration and Extraction segment and were reviewed by the Independent Engineering Firms (as defined below), which audit the estimates of our oil and gas reserves. Pursuant to the *Lineamientos que Regulan los Procedimientos de Cuantificación y Certificación de Reservas de la Nación* (Guidelines for Regulating the Nation's Reserves Quantification and Certification Procedures), the Ministry of Energy must review the proved reserves reports estimates every year and issue a resolution no later than the second week of April of the following year, or in some unforeseen circumstances, no later than the second week of September. However, as of the date of this annual report, the Ministry of Energy has not yet issued a resolution with respect to the reserves report as of December 31, 2025. See "*Item 3—Key Information—Risk Factors—Risk Factors Related to our Relationship with the Mexican Government—Hydrocarbon reserves are based on estimates, which are uncertain and subject to revisions.*"

We estimate reserves based on generally accepted petroleum engineering and evaluation methods and procedures, which are based primarily on applicable SEC regulations and, as necessary, the Society of Petroleum Engineers' (which we refer to as the SPE) publication entitled Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information, dated June 25, 2019 and other SPE publications, as amended, including the SPE's publication entitled Petroleum Resources Management System, as well as other technical sources, including Estimation and Classification of Reserves of Crude Oil, Natural Gas, and Condensate, by Chapman Cronquist, and Determination of Oil and Gas Reserves, Petroleum Society Monograph Number 1, published by the Canadian Institute of Mining and Metallurgy & Petroleum. The choice of method or combination of methods employed in the analysis of each reservoir is determined by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• experience in the area;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• stage of development;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• quality and completeness of basic data; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• production and pressure histories.

Reserves data set forth herein represent only estimates. Reserves valuation is a subjective process of estimating underground accumulations of crude oil and natural gas that cannot be measured in an exact manner. The accuracy of any reserves estimate depends on the quality of available data, engineering and geological interpretation and professional judgment. As a result, estimates of different engineers may vary. In addition, the results of drilling, testing and producing subsequent to the date of an estimate may lead to the revision of an estimate. See "*Item 3—Key Information—Risk Factors—Risk Factors Related to our Relationship with the Mexican Government— Hydrocarbon reserves are based on estimates, which are uncertain and subject to revisions*."

During 2025, we did not record any material increase in our proved oil and gas reserves as a result of the use of new technologies.

In order to ensure the reliability of our reserves estimation efforts, we have undertaken the internal certification of our estimates of reserves since 1996. We have established certain internal controls in connection with the preparation of our

proved reserves estimates. Initially, teams of geoscientists from our exploration and production business units (with each of these units covering several projects) prepare the reserves estimates, using distinct estimation processes for valuations relating to new discoveries and developed fields, respectively. Subsequently, the regional reserves offices collect these reserves estimates from the units and request that the *Gerencia de Recursos y Reservas de Hidrocarburos* (Office of Resources and Hydrocarbon Reserves), the central hydrocarbon reserves management body of Petróleos Mexicanos, review and certify such valuations and the booking of the related reserves. This internal certification process is undertaken in accordance with internal guidelines for estimating and classifying proved reserves, which are based on the SEC's rules and definitions. The Office of Resources and Hydrocarbon Reserves, which also oversees and conducts an internal audit of the process described above, consists entirely of professionals with geological, geophysical, petrophysical and reservoir engineering backgrounds. Additionally, the engineers who participate in our reserves estimation process are experienced in: reservoir numerical simulation; well drilling and completion; pressure, volume and temperature (PVT) and analytical tools used in forecasting the performance of the various elements comprising the production system; and design strategies in petroleum field development. Furthermore, all of our personnel have been certified by the *Secretaría de Educación Pública* (Ministry of Public Education), most have earned master's degrees in areas of study such as petroleum engineering, geology and geophysical engineering and they possess an average of 20 years of professional experience.

In addition to this internal review process, our Exploration and Extraction segment's final reserves estimates are audited by independent engineering firms. Three independent engineering firms audited our estimates of proved reserves as of December 31, 2025, or January 1, 2026, as applicable: DeGolyer and MacNaughton, GLJ and Ryder Scott (we refer to these firms together as the "Independent Engineering Firms"). The reserves estimates reviewed by the Independent Engineering Firms represented 76.1% of our estimated proved reserves. The remaining 23.9% of our estimated proved reserves consisted mainly of reserves located in certain onshore fields in northern Mexico and certain offshore fields, including areas that have been shared with third-parties through Exploration and Production (E&P) contracts.

GLJ audited the reserves in the Cantarell, Ku-Maloob-Zaap, Reynosa, Veracruz, Cinco Presidentes and Macuspana-Muspac business units, Ryder Scott audited the reserves in the Poza Rica-Altamira, Bellota-Jujo, Samaria-Luna, Abkatún-Pol-Chuc and Litoral de Tabasco business units, and DeGolyer and MacNaughton audited the reserves in the fields recently added to our inventory registry. The audits conducted by the Independent Engineering Firms consisted primarily of: (1) analysis of historical static and dynamic reservoir data that we have provided; (2) construction or updating of the Independent Engineering Firms' own static and dynamic reservoir characterization models of some of our fields; (3) economic analysis of fields; and (4) review of our production forecasts and reserves estimates.

Since reserves estimates are, by definition, only estimates, they cannot be reviewed for the purpose of verifying exactness. Instead, the Independent Engineering Firms conducted a detailed review of our reserves estimates so that they could express an opinion as to whether, in the aggregate, the reserves estimates we furnished were reasonable and had been estimated and presented in conformity with generally accepted petroleum engineering and evaluation methods and procedures.

All questions, including any suggested modifications to proved reserves estimates, that arose during the Independent Engineering Firms' review process were resolved by our Exploration and Extraction segment to the satisfaction of the Independent Engineering Firms. The Independent Engineering Firms concluded that our estimated total proved oil and natural gas reserve volumes set forth in this report are, in the aggregate, reasonable and have been prepared in accordance with Rule 4-10(a) of Regulation S-X of the SEC, as amended (which we refer to as Rule 4-10(a)), are consistent with international reserves reporting practice and are in accordance with the revised oil and gas reserves disclosure provisions of ASC Topic 932.

Our total proved developed and undeveloped reserves of crude oil, condensates and liquefiable hydrocarbons recoverable from field processing plants decreased by 2.6% in 2025, from 5,494.5 million barrels in 2024 to 5,351.9 million barrels in 2025. This decrease was the result of a slightly lower variation in proved reserves due to discoveries, developments, delineations and revisions. The fields that were categorized as proved reserves due to drilling of development wells, new discoveries and revisions were mainly: Ixachi, Bakte, Akal, Zaap, Teotleco, Maloob, Abkatún, Balam, Koban, Mulach, Tajín, Bricol, Coapechaca, Racemosa, Pokche, Takín, Taratunich, Tsimín, Tlacame, Nohoch, Sini, Homol, Konen, Xanab and Rabasa. Our proved developed reserves of crude oil, condensates and liquefiable hydrocarbons recoverable from processing plants decreased by 8.7% in 2025, from 3,463.9 million barrels in 2024 to 3,162.1 million barrels in 2025. Our proved reserves of crude oil, condensates and liquefiable hydrocarbons added in 2025 through revisions, extensions and discoveries totaled 507.4 million barrels, which was insufficient to offset our total production for the year of 650.0 million barrels of crude oil, condensates and liquefiable hydrocarbons.

Our total proved developed and undeveloped dry gas reserves increased by 8.4% in 2025, from 10,173.6 billion cubic feet at December 31, 2024 to 11,025.9 billion cubic feet at December 31, 2025. Our proved developed dry gas reserves increased by 22.2% in 2025, from 5,773.4 billion cubic feet at December 31, 2024 to 7,054.0 billion cubic feet at December 31, 2025. This increase was principally due to an increase in proved developed dry gas reserves of the Ixachi field. The amount of dry gas reserves added in 2025 was sufficient to offset the level of production in 2025, which amounted to 901.0 billion cubic feet of dry gas. Our proved undeveloped dry gas reserves decreased by 9.7% in 2025, from 4,400.2 billion cubic feet at December 31, 2024 to 3,971.9 billion cubic feet at December 31, 2025. This decrease in proved undeveloped reserves was due to the development of the Ixachi field, mainly due to the drilling of development wells and revisions, which allowed these reserves to be classified as proven developed reserves.

During 2025, our exploration activity in the shallow waters of the Gulf of Mexico and onshore regions resulted in the discovery of two new hydrocarbon fields (Konen and Iklum) and the extension of an existing field (Bakte) due to an appraisal well that was found viable. Together, these discoveries and extension amounted to the incorporation of 12.2 million barrels of oil equivalent of proved reserves.

In 2025, our proved reserves increased by 21.3 million barrels of oil equivalent, as a result of accounting for discoveries, development, reclassifications and revisions.

The following three tables of crude oil and dry gas reserves set forth our estimates of our proved reserves determined in accordance with Rule 4-10(a).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Proved reserves, developed reserves and undeveloped reserves are expressed in millions of barrels of oil equivalent. To convert dry gas to barrels of oil equivalent, a factor of 5.201 thousand cubic feet of dry gas per barrel of oil equivalent is used.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Undeveloped Locations refers to the number of geographic sites or locations where a well will be drilled to produce undeveloped proved reserves.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)Includes extraction assignments and temporary assignments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4)These fields are part of Petróleos Mexicanos' exploitation contract without partner, Ek-Balam.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5)Includes the Cunduacán, Iride, Oxiacaque, Platanal and Samaria fields.

Our RRR for a given period is calculated by dividing the sum of proved reserves additions due to discoveries, developments, delineations and revisions by that period's total production. During 2025, we obtained 844.5 million barrels of oil equivalent of proved reserves, which represents a RRR of 102.6%, an increase as compared to a RRR of 96.6% in 2024. Although our RRR has trended downwards in recent years and decreased below 100% in 2024, our RRR surpassed 100% in 2025, and we expect to continue achieving a RRR of around 100% in the following years.

Our reserves production ratio, which is presented in terms of years, is calculated by dividing the estimated remaining reserves at the end of the relevant year by the total production of hydrocarbons for that year. As of December 31, 2025, this ratio was 9.1 years for proved reserves.

For more information, see Note 30 to our consolidated financial statements included herein.

In 2025, our average production cost was U.S.$13.46 per barrel of oil equivalent, which represented a decrease of 0.2%, as compared to our average production cost of U.S.$13.49 per barrel of oil equivalent in 2024. This decrease is attributed mainly to the optimization of product consumption, reduction in royalty payments and decrease in the cost of indirect items (overhead).

We calculate and disclose our production costs pursuant to international practices, which are based on U.S. GAAP under ASC Topic 932. In accordance with ASC Topic 932, the production cost per barrel of oil equivalent is calculated by dividing total production expenses (in U.S. dollars) by total production of oil and gas (in barrels of oil equivalent) for the relevant period.

Our total production cost consists of all direct and indirect costs incurred to produce crude oil and gas, including costs associated with the operation and maintenance of wells and related equipment and facilities. In addition, it includes costs of labor to operate the wells and facilities, the costs of materials, supplies and fuel consumed, including gas used for gas lifting, nitrogen and other chemicals, repair and non-capitalized maintenance costs, and other costs, such as fees for general services, a labor fund for active personnel, corporate services, indirect overhead and applicable taxes and duties. However, it excludes non-cash expenses such as amortization of capitalized well expenses, the depreciation of fixed assets, expenses associated with the distribution and handling of oil and gas and other expenses that are related to exploration, development and drilling activities.

*Crude Oil and Natural Gas Production*

In 2025, we produced an average of 1,618.5 thousand barrels per day of crude oil, a decrease of 7.0% as compared to our average production of 1,741.1 thousand barrels per day of crude oil in 2024. The decrease in 2025 is mainly due to a decline in production at some of our main fields, including Zaap, Quesqui, Xanab, Tupilco Profundo and Pokche, as a result of bad weather conditions affecting the continuity of offshore operations and delays in the completion of wells with high complexity due to their depth, pressure and temperature conditions. Our average production of heavy crude oil decreased by 104.8 thousand barrels per day, or 11.4% less than the average daily production in 2024, mainly due to the natural decline of the Ku, Zaap, Ek, Balam and Akal fields. In 2025, the average production of light crude oil decreased by 17.8 thousand barrels per day, or 2.2%, as compared to 2024. The decrease in light crude oil production was mainly due to the natural decline of the Quesqui, Tupilco Profundo, Xanab, Pokche and Itta fields.

Crude oil can be classified by its sulfur content. "Sour" or heavy crude oil contains 3.4% or greater sulfur content by weight and "sweet" or light crude oil contains less than 1.0% sulfur content by weight. Most of our production is classified as sour or heavy crude oil.

Our Exploration and Extraction segment primarily produces five types of crude oil:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.Altamira, a heavy crude oil;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.Maya, a heavy crude oil;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.Zapoteco, a light crude oil;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.Istmo, a light crude oil; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.Olmeca, an extra-light crude oil.

Most of our production consists of Istmo and Maya crude oil. In 2025, 50.3% of our total production of crude oil consisted of heavy crude oil and 49.7% consisted of light and extra-light crude oil. The Marine regions yield mostly heavy crude oil (71.6% of these regions' production in 2025), although significant volumes of light and extra light crude oil are also produced there (28.4% of these regions' production in 2025). The Southern region yields mainly light and extra-light crude oil (together, 94.5% of this region's production in 2025, as well as lesser amounts of heavy crude oil (5.5% of this region's production in 2025) and the Northern region yields both light and extra-light crude oil (71.0% of this region's production in 2025) and heavy crude oil (29.0% of this region's production in 2025).

The most productive crude oil and natural gas fields in the Gulf of Mexico are located in the Ku-Maloob-Zaap, Litoral de Tabasco, Abkatún-Pol-Chuc and Cantarell business units in the Marine regions, Bellota-Jujo business units in the Southern region and Veracruz business units in the northern region. In particular, the Ku-Maloob-Zaap business unit remained our most important crude oil producer in 2025, producing an average of 530.5 thousand barrels per day of crude oil in 2025, or 32.8% of our total crude oil production for the year, and 839.1 million cubic feet per day of natural gas, or 18.4% of our total natural gas production for the year. Our second most important crude oil producer was Litoral de Tabasco which produced an average of 277.4 thousand barrels per day of crude oil in 2025, or 17.1% of our total crude oil production for the year, and an average of 473.7 million cubic feet per day of natural gas, or 10.4% of our total natural gas production for the year.

The following table sets forth our annual crude oil production rates by type of oil for the five years ended December 31, 2025.

In addition, we invested Ps.45,490 million in nominal terms in new fields under construction and development (48.5% of the total). The remaining 24.8% amounted to Ps.23,601.0 million in nominal terms, which was directed to the 12 remaining projects, as well as to other exploration, drilling and services projects.

*Exploration and Extraction Capital Expenditures and Budget* 

For 2026, our total capital expenditures budget is Ps.86,693 million, as compared to Ps.93,771 million of capital expenditures made in 2025, representing a decrease of 7.5% to reflect a budgetary rebalancing. Our 2026 budget includes Ps.38,770 million allocated to all 23 ongoing strategic exploration and extraction projects, Ps.33,959 million allocated to new fields under development, Ps.13,964 million allocated to other exploration projects. Of our total exploration and extraction investment budget for 2026, Ps.72,518 million, or 83.6 % of the total, is allocated to investments in fields and development projects, and the remaining Ps.14,175 million, or 16.4% of the total, is allocated to exploration activities.

The 2026 budget for exploration and extraction activity includes (i) Ps.12,582 million for investments in Ku-Maloob-Zaap, (ii) Ps.5,913 million for investments in Integral Yaxché, (iii) Ps.2,423 million for investments in Chuc, (iv) Ps.2,227 million for investments in Ek-Balam, (v) Ps.1,612 million for investments in Bellota Chinchorro, (vi) Ps.1,513 million for investments in Cuenca de Veracruz, (vii) Ps.1,504 million for investments in Cactus-Sitio Grande, (viii), Ps.1,342 million for investments in Aceite Terciario del Golfo, (ix) Ps.1,326 million for investments in Antonio J. Bermúdez and (x) Ps.1,154 million for investments in Tsimin-Xux. These 10 projects totaled Ps.31,596 million, Ps. 33,959 million were allocated to development of new fields projects and the remaining Ps.21,138 million for other projects.

*Exploration and Extraction Investment Trends* 

In nominal terms, we invested Ps. 20,866 million in exploration activities during 2025, which represented 22.3% of the total capital expenditures of our Exploration and Extraction segment. This represented a 45.9% decrease from the Ps. 38,574 million invested in exploration activities in 2024. In 2025, we invested Ps. 72,905 million in nominal terms, or 77.7% of the total capital expenditures of our Exploration and Extraction segment in development and exploration activities. This represented a 41.2% decrease from the Ps. 124,042 million invested in these activities in 2024.

For 2026, we have budgeted Ps. 14,175 million in exploration activities, or 16.4% of our total capital expenditures budget, for exploration activities of our Exploration and Extraction segment. This represents a 32.1% decrease from the amount we invested in exploration activities in 2025. For development activities in 2026, we have budgeted Ps. 72,518 million, or 83.6% of total capital expenditures of our Exploration and Extraction segment. This represents a 0.5% decrease compared to the amount that we invested in these activities in 2025.

Our projected exploration and development capital expenditures correspond to the areas assigned to us through bidding rounds, which represent the areas in which we are exploring, operating or have an interest in developing based on our operational capabilities. The Ministry of Energy granted us the right to explore and develop these areas with the objective of maintaining our production levels in the short term, while providing us with sufficient exploration opportunities to increase our production in the future. During 2025, we continued evaluating the use of CSIEEs as a replacement for farm-outs to foster private sector participation in our operations. The CSIEE model seeks to increase production by offering an incentive based on the production received and sharing the risk involved in operations according to the terms of each contract. Each CSIEE contract has a term of between 15 and 25 years. CSIEE contracts are expected to replace farm-outs as a vehicle for private sector participation, although existing farm-outs will remain for the duration of their respective terms. These contracts establish the respective contractual rights and obligations of the parties concerning the development, extraction and production of hydrocarbons. Exploration activities may also be included, subject to governmental approval.

As of March 19, 2025, the Hydrocarbons Sector Law permits private sector participants to carry out exploration and extraction activities as joint operators with Petróleos Mexicanos under mixed development agreements.

Mixed contracts remain in the bidding stage and will be awarded and signed starting in 2026.

As of December 31, 2025, we have signed five CSIEE contracts related to exploration and extraction. For more information regarding CSIEEs, see "*—Crude Oil Distribution—Farm-outs and CSIEEs*."

The capital expenditures of our Exploration and Extraction segment have represented between 67.0% and 82.2% of our total capital expenditures of the previous three years. In 2026, the capital expenditures budget for our Exploration and Extraction segment comprised 65.7% of our total capital expenditures.

The following tables sets forth our capital expenditures, excluding non-capitalizable maintenance, related to exploration and development for each of the three years ended December 31, 2025, 2024 and 2023, as well as the budget for 2026. Capital expenditure amounts derive from our budgetary records, which are prepared on a cash basis. Accordingly,

these capital expenditure amounts do not correspond to capital expenditure amounts included in our consolidated financial statements prepared in accordance with IFRS.

*Cantarell Project.* Project Cantarell is located on the continental shelf of the Gulf of Mexico. It consists of the Akal, Chac, Ixtoc, Kambesah, Kutz, Nohoch, Sihil and Takin fields, which extend over an area of 294.4 square kilometers. As of December 31, 2025, there were a total of 573 wells drilled in the Cantarell project, 79 of which were producing. During 2025, Cantarell was the fourth most important producer of crude oil in Mexico, averaging 51.8 thousand barrels per day of crude oil. This represented a decrease of 2.8% from 2024 due to the decline of the remaining crude oil reserves in these fields. Natural gas production from Cantarell during 2025 averaged 579.3 million cubic feet per day. This was 2.6% lower than the 2024 average natural gas production.

As of December 31, 2025, the cumulative production of Cantarell amounted to 14.5 billion barrels of crude oil and 12.4 trillion cubic feet of natural gas. As of December 31, 2025, Cantarell's proved oil and gas reserves amounted to 191.5 million barrels of crude oil and 1,621.4 billion cubic feet of natural gas. As of December 31, 2025, total proved reserves amounted to 687.7 million barrels of oil equivalent, 205.9 million of which were proved developed reserves.

The Akal field, which is the most important field in Cantarell, averaged 16.9 thousand barrels per day of crude oil production during 2025. This was 9.7% more than the average production in 2024, which amounted to 15.4 thousand barrels per day.

In nominal peso terms, our Exploration and Extraction segment's capital expenditures for Cantarell amounted to Ps.849 million in 2024 and Ps.43 million in 2025. Our total accumulated capital expenditures for this project were U.S$42.31 billion as of December 31, 2025. We expect that our capital expenditures for this project will total Ps.782 million in 2026.

On October 10, 1997, we awarded a build-own-operate contract for a nitrogen cryogenic plant at Cantarell to a consortium formed by BOC Holdings, Linde, Marubeni, West Coast Energy and ICA Fluor Daniel. Under this contract, the consortium is responsible for the financing, design, construction and operation of the plant. The plant began operations in 2000 and cost Ps.10,131 million. Pursuant to the terms of the agreement, we have the right to acquire the nitrogen plant in the case of a default by the consortium. We have the obligation to acquire the nitrogen plant if we default under the contract. Under the terms of the contract, we committed to purchasing 1.2 billion cubic feet per day of nitrogen from the consortium and to continue to supply service through June 2027.

During 2025, we paid U.S.$188.0 million under this contract for an approximate total volume of 408.5 billion cubic feet of nitrogen, which was injected into the Cantarell fields. In 2026, our exploration and production segment expects to pay U.S.$203.0 million under this contract for an approximate total volume of 433.4 billion cubic feet of nitrogen to be injected into the fields.

*Ogarrio-Sánchez Magallanes Project.* Project Ogarrio-Sánchez Magallanes comprises 16 crude oil and natural gas producing fields and forms part of the Cinco Presidentes business unit. This project is located between the state borders of Veracruz and Tabasco and covers an area of 10,820 square kilometers. From a geological standpoint, this project pertains to the Isthmus Saline basin, specifically the southeastern basins at the Tertiary level. Ogarrio-Sánchez Magallanes is geographically bounded by the Gulf of Mexico to the north, the geological folds of the Sierra Madre of Chiapas to the south, the Tertiary basin of Veracruz to the west and the Comalcalco Tertiary basin to the east. The primary objective of this project is to increase production levels through the drilling of development wells and infill wells, which are drilled between producing wells to recover oil and gas reserves more efficiently, the execution of workovers of wells and the implementation of secondary and enhanced oil recovery processes. In addition, we aim to optimize the infrastructure of this project in order to counteract the decreases in production levels that result from the natural depletion of its reservoirs.

As of December 31, 2025, Ogarrio-Sánchez Magallanes had 200 producing wells. Average daily production amounted to 23.8 thousand barrels of crude oil and 25.9 million cubic feet of natural gas during 2025. As of December 31, 2025, cumulative production amounted to 1.4 billion barrels of crude oil and 2.0 trillion cubic feet of natural gas. Proved hydrocarbon reserves amounted to 46.3 million barrels of crude oil and 80.9 billion cubic feet of natural gas. Total proved reserves amounted to 63.3 million barrels of oil equivalent, of which 57.3 million barrels were proved developed reserves.

In nominal peso terms, our capital expenditures for Ogarrio-Sánchez Magallanes amounted to Ps.1,936 million in 2024 and Ps.744 million in 2025. As of December 31, 2025, our total accumulated capital expenditures for this project were U.S.$710.9 million. We expect that our capital expenditures for this project will total Ps.1,088 million in 2026.

*Antonio J. Bermúdez Project.* Project Antonio J. Bermúdez is designed to accelerate reserves recovery, as well as increase the recovery factor, by drilling additional wells and implementing a system of pressure maintenance through nitrogen injection. It consists of the Samaria, Cunduacán, Oxiacaque, Iride and Platanal fields, and covers an area of 163 square kilometers. As of December 31, 2025, a total of 910 wells had been completed, of which 169 were producing. During 2025, the project produced an average of 23.2 thousand barrels per day of crude oil and 40.5 million cubic feet per day of natural gas.

During 2025, proved reserves decreased by 12.2 million barrels of oil equivalent, from 76.4 million barrels of oil equivalent in 2024 to 64.2 million barrels of oil equivalent in 2025. This decrease was primarily due further production decline at some Burgos project fields.

In nominal peso terms, our Exploration and Extraction segment's capital expenditures (including capital expenditures made pursuant to Financed Public Works Contracts, or "FPWCs") for Burgos amounted to Ps.1,312 million in 2024 and Ps.314 million in 2025. As of December 31, 2025, our total accumulated capital expenditures for this project were U.S.$20.7 billion. We expect that our capital expenditures for this project will total Ps.550 million in 2026.

*Aceite Terciario del Golfo Project (Project ATG, formerly Paleocanal de Chicontepec).* Project ATG is located in the Northern region and covers an area of 4,243 square kilometers. This project comprises 29 fields, which are divided among eight sectors. As of December 31, 2025, there was a total of 4,787 wells completed, of which 1,140 were producing. The project produced an average of 13.6 thousand barrels per day of crude oil in 2025 as compared to 15.7 thousand barrels per day of crude oil in 2024, which represents a 13.4% decrease. Additionally, Project ATG produced an average of 26.5 million cubic feet per day of natural gas in 2025, as compared to 29.9 million cubic feet of natural gas per day in 2024, which represents a 11.4% decrease. The decrease in natural gas production was primarily due to the decline in pressure in certain reservoirs. As of December 31, 2025, cumulative production was 371.4 million barrels of crude oil and 813.7 billion cubic feet of natural gas. As of December 31, 2025, proved reserves totaled 491.3 million barrels of crude oil and 903.4 billion cubic feet of natural gas. Total proved hydrocarbon reserves were 615.1 million barrels of oil equivalent, of which 146.6 million barrels of oil equivalent were proved developed reserves.

During 2025, field development activities at the project included drilling ten new wells and the completion of eight wells, all of which were classified as producing. As of December 31, 2025, 91.7% of the total producing wells were operating with artificial systems such as mechanical, pneumatic, hydraulic and electric pumping, while the remaining 8.3% were "flowing wells" that are classified accordingly because they did not require any means of artificial lift.

In nominal peso terms, our Exploration and Extraction segment's capital expenditures for Project ATG amounted to Ps.1,373 million in 2024 and Ps.446 million in 2025. As of December 31, 2025, our total accumulated capital expenditures for this project were U.S.$13.5 billion. We expect that our capital expenditures for this project will total Ps.1,342 million in 2026.

*Crude Oil Sales* 

During 2025, domestic consumption of crude oil amounted to 1,026.4 thousand barrels per day, which represented 63.4% of our total crude oil production. Through PMI's activities, we sold the remainder of our crude oil production abroad. Maya crude oil accounted for 63.0% of exported crude oil volume sold by PMI in 2025. See "*—Business Overview—International Trading*" in this Item 4.

The following table sets forth crude oil distribution for the past five years.

The differences between the volume of crude oil measured at the wellhead and the volume distributed reflect customary adjustments due to, among other things, the stabilization process of the crude oil and decreases caused by evaporation and conditioning. In the past, we have identified increases in the difference between oil production and crude oil distribution volumes that have remained within established limits. Therefore, based on an analysis carried out in coordination with the Ministry of Energy, we have implemented corrective actions to improve our measurement methodology, balance sheets and measurement management system, including permanent monitoring of wells, periodic verifications of measurement systems with maintenance and improvement programs, calibration of measurement equipment, and installation of additional dehydration systems, to increase the reliability of volume measurement. Additionally, the volume of crude oil measured in barrels goes through a stabilization process in preparation for export, which involves a triple certification by us, the buyer and a third party to verify that the content meets international standards, ensuring that the volume of crude oil measured in barrels does not contain more than 0.5% of water and 50 pounds/1,000 barrels of salt.

*Gas Flaring*

Gas flaring, which consists of the burning of gas not used in production facilities, usually occurs due to operational adjustments required for maintenance purposes, as well as limitations in the processing and transportation of natural gas. In addition, the burning of gases is also used as a safety measure, releasing high pressures caused by interruptions in the conditioning, handling and transportation processes.

The burning of gases is considered the most significant atmospheric emission from offshore and onshore oil and gas facilities into the atmosphere. In 2025 this represented 10.3% of total gas production, compared to 4.8% of gas production in 2024. The increase in gas flaring was mainly due to a lack of infrastructure for gas handling at onshore facilities.

*Pipelines*

Our crude oil and natural gas pipeline network connects crude oil and natural gas producing centers with refineries and petrochemical plants. At the end of 2025, this pipeline network consisted of approximately 36,278 kilometers of pipelines, of which 2,075 kilometers were located in the Northeast Marine region, 1,716 kilometers were located in the Southeast Marine region, 7,939 kilometers were located in the Southern region and 24,549 kilometers were located in the Northern region. For a description of products transported by the pipeline network, see "*—Business Overview—Logistics*" in this Item 4.

*Integrated Exploration and Production (E&P) Contracts, Financed Public Works Contracts (FPWCs) and Integrated Exploration and Extraction Services Contracts (CSIEEs)*

Our FPWC program, previously known as the Multiple Services Contracts program, was first announced in December 2001. The objective of the program was to provide a contractual framework that promotes efficient execution of public works in order to increase Mexico's oil and gas production. These were contracts based on unit prices that aggregate a number of different services into a single contract. Under the FPWC framework, Petróleos Mexicanos retains entitlements for all oil and gas produced as well as works performed under each FPWC.

Our Integrated E&P Contracts program was established as part of reforms to the Mexican energy sector enacted in 2008. The objective of these contracts was to increase our execution and production capabilities. The oil and gas reserves located in and extracted from the areas to which we have a legal right, continue to be owned exclusively by the Mexican Government. Under this program, payments to the contractors were made on a per-barrel basis, plus recovery costs, not exceeding our cash flow from the block.

We may amend our Integrated E&P Contracts and FPWCs in order to align these contracts with the contractual framework established under the Hydrocarbons Law. As part of this reform, existing Integrated E&P Contracts or FPWCs may be migrated into a contract for exploration and extraction upon agreement by the contract parties to the technical guidelines established by the Ministry of Energy (after seeking our favorable opinion) and the financial terms determined by the Ministry of Finance and Public Credit. Upon approval by the contract parties, the existing Integrated E&P Contract or FPWC will be terminated and be replaced by the new contract for exploration and extraction without the need for a bidding process. If the contract parties do not agree to the proposed technical guidelines and contractual and financial terms, the original Integrated E&P Contract or FPWC remains in effect.

As of the date of this annual report, we have migrated three Integrated E&P Contracts to contracts for exploration and extraction:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On December 18, 2017, the Integrated E&P Contract governing the Santuario and El Golpe blocks was migrated;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On August 3, 2018, the Integrated E&P Contract governing the Ebano block was migrated; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On November 21, 2018, the Integrated E&P Contract governing the Miquetla block was migrated.

In addition, we migrated the FPWCs governing Misión and Olmos blocks on March 2, 2018 and February 22, 2018, respectively, to different contractual frameworks allowed under the Petróleos Mexicanos Law. For more information on the migration of these Integrated E&P Contracts and FPWCs, see "*—Other Exploration and Extraction Contracts*" below.

The goal of these contract amending agreements strategy is to increase our hydrocarbon production and to meet our reserve replacement objectives at competitive costs. As of the date of this annual report, we have not amended any agreement for existing FPWCs or Integrated E&P Contracts to CSIEEs or similar contracts.

In 2025, natural gas production in the current FPWC blocks reached 23.8 million cubic feet per day and condensate production reached 0.9 thousand barrels per day, for a total of 4.4 thousand barrels of oil equivalent per day.

In 2025, production in the existing CSIEE reached 5.3 thousand barrels per day of crude oil and 29.0 million cubic feet per day of natural gas, for a total of 10.7 thousand barrels of oil equivalent per day.

During 2025, contractors expended U.S.$72.0 million in connection with Integrated E&P Contracts. In 2025, production in the existing Integrated E&P blocks reached 6.0 thousand barrels per day of crude oil and 14.5 million cubic feet per day of natural gas, for a total of 8.9 thousand barrels of oil equivalent per day.

*Farm-outs and CSIEEs*

Through farm-outs, we sell a partial interest in fields that have been granted to us and enter into agreements for the joint operation of such fields. This requires third parties to make financial contributions to the partnership and to provide field services, allowing us to recoup some of our previous investments in the fields and to share some of the risk associated with the further development of the fields, while maintaining an interest in the future profits.

On December 11, 2018, the Mexican Government announced the suspension of bidding rounds for exploration and extraction of hydrocarbons contracts for a three-year period in order to evaluate the results and progress of the existing

contracts. On June 13, 2019, the Mexican Government announced the suspension of bidding rounds for new farm-outs to provide an opportunity to evaluate the performance of existing farm-outs. The existing farm-outs will continue to operate in accordance with the terms and conditions of their respective contracts. We understand the Mexican Government will use the results of such evaluation to determine whether to pursue farm-outs in the future.

The CSIEE model seeks to increase production by providing incentive-based remuneration dependent on the production received and sharing the operating risks according to the terms of each contract. Currently, five CSIEE have been subscribed:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Cuitláhuac: This CSIEE contract was signed on July 25, 2023 and covers the assets A-0112-M-Campo Cuitláhuac, located in the Northwest portion of the Burgos Basin, southwest of the city of Reynosa, Tamaulipas. This development plan aims to recover 218.2 billion cubic feet of wet gas, equivalent to 41.0 million barrels of oil equivalent, over the course of the contract's 15-year term.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Bacab-Lum: This CSIEE contract was signed on July 1, 2024 and consists of two extraction assets: A-0035-3M – Campo Bacab and A-0196-M – Campo Lum, located in territorial waters west of the Yucatán Peninsula in the Gulf of Mexico. This development plan aims to recover a volume of 73.2 million barrels of oil and 17.5 billion cubic feet of associated gas, equivalent to 76.1 million barrels of oil equivalent, over the course of the contract's 15-year term.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Lakach: This CSIEE contract was signed on July 5, 2024 and encompasses the deepwater asset A-0188-M – Campo Lakach, located in the territorial waters in the Gulf of Mexico off the shores of the state of Veracruz. With this business scheme, it is estimated to recover a reserve volume of 847.9 billion cubic feet of gas, equivalent to 149.0 million barrels of oil equivalent, over the course of the contract's 15-year term.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Coapechaca Block IV: This CSIEE contract was signed on November 27, 2024. This block is located inside the asset A-0094-5M-Campo Coapechaca in northern Veracruz. It is estimated to obtain a volume of 26.7 million barrels of oil and 46.7 billion cubic feet of associated gas, equivalent to 31.8 million barrels of oil equivalent over the course of the contract's 15-year term.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Coapechaca Block II: This CSIEE contract was signed on January 30, 2025. This block is located inside the asset A-0094-5M-Campo Coapechaca in northern Veracruz. It is estimated to obtain a volume of 22.01 million barrels of oil and 31.02 billion cubic feet of associated gas, equivalent to 25.37 million barrels of oil equivalent over the course of the contract's 15-year term.

*Trión Farm-out*

On July 28, 2016, the National Hydrocarbons Commission published the tender offer and bidding package to select a partner for the former Pemex Exploration and Production subsidiary entity to carry out exploration and production activities in the Trión block, which is located in the Perdido Fold Belt in the Gulf of Mexico. Considering that Trión block has a depth greater than 2,500 meters, it requires a high level of technical expertise and financial investment to develop the block.

On December 5, 2016, the National Hydrocarbons Commission announced that BHP Billiton Petróleo Operaciones de México, S. de R.L. de C.V., or BHP Billiton Mexico, an affiliate of BHP Group Limited and BHP Group Plc, had been selected as the partner for Pemex Exploration and Production in the Trión block farm-out. Pursuant to the terms of its bid, BHP Billiton Mexico made a U.S.$624 million contribution to the partnership in exchange for a 60% participating interest in the Trión Block. BHP Billiton Mexico is the actual operator of the Trión block and must invest U.S.$1.9 billion in the Trión farm-out before we are required to invest in the project, which will likely not occur until 2025. The corresponding exploration and extraction contract, joint operating agreement and other relevant agreements were executed on March 3, 2017, and the National Hydrocarbons Commission approved both the exploration and evaluation plans in February 2018.

The final evaluation report was approved by the National Hydrocarbons Commission on February 18, 2022. On March 8, 2022, the National Hydrocarbons Commission approved the Declaration of Commerciality of the Trión Field, granting two years to file the Development Plan for Extraction. On June 1, 2022, BHP's oil and gas portfolio merged with Woodside to create a global top 10 independent energy company by production, the merged business was owned approximately 52% by existing Woodside shareholders and 48% by existing BHP shareholders.

The first exploration period ended on September 29, 2022. On December 16, 2022, the National Hydrocarbons Commission accredited 201,167 work units carried out by the contractor of the 186,150 work units of the evaluation program and the exploration plan. The development plan for extraction was delivered to the National Hydrocarbons Commission on June 29, 2023. On August 29, 2023, the National Hydrocarbons Commission approved the development plan for extraction. Production is scheduled to start in August 2028.

On October 19, 2023, the early termination procedure for the reduction and return of a portion of the contract area, from 1,285.2 km<sup>2</sup> to 36.7 km<sup>2</sup>, as a result of the relinquished area not forming part of the development or extraction area. On September 26, 2024, the third modifying agreement of CNH-A1-TRION/2016 was executed to reflect the new delimitation of the contract area.

Construction of the Trión Floating Production Unit (FPU) began on November 1, 2024. On December 12, 2024, the operator, Woodside Petróleo Operaciones de México S. de R.L. de C.V., opened its offices in Tampico, Tamaulipas.

During 2024, the Unique Registration Code, environmental impact assessment, and registration applications of the operator, Woodside Petróleo Operaciones de México S. de R.L. de C.V. ("WDS"), were submitted to the *Agencia Nacional de Seguridad Industrial y de Protección al Medio Ambiente del Sector Hidrocarburos* (National Agency for Industrial Safety and Environmental Protection of the Hydrocarbons Sector, or "ASEA") and the Trión FPU was assigned to the Deepwater Thalassa drilling platform. During 2024, the project development phase had incurred total expenditures of U.S.$765.0 million and had achieved overall progress of 20%. In November 2024, construction of the FPU "Tlaloc" began by HHI (Hyundai Heavy Industries) in Korea. On December 12, 2024, the operator inaugurated its offices in Tampico, Tamaulipas.

As of January 1, 2025, the National Hydrocarbons Commission certified a total volume of 3P reserves of 630.2 million barrels of oil equivalent. In February 2025, construction began on the buoy for the disconnectable turret module of the floating storage and offloading ("FSO") unit. On September 20, 2025, construction of the FSO "Chalchi" by COSCO began in China.

On December 9, 2025, the fourth amendment to the exploration and extraction contract agreement was signed, reflecting the change in our legal regime to a state-owned public company. On December 17, 2025, the Pemex "Secondee" Seconded Personnel Contract was signed between WDS and us. As of December 31, 2025, the project was 50.4% complete and we had contributed U.S.$384 million in cash requests. Progress by facility was 82.3% in the FPU, 39.2% in the FSO, 59.7% in the SURF and, 43.1% in the GGL.

Regulatory permits progressed during December 2025 with the approval of the Industrial Safety, Operational Safety and Environmental Protection Administration System (SASISOPA) by ASEA and the well drilling permit granted by the Ministry of Energy for the first eight wells. These approvals allow field activities to begin. Well drilling commenced in March 2026 with the Deepwater Thalassa drillship (Transocean).

*Ogarrio, Cárdenas-Mora and Ayin-Batsil Farm-outs*

In addition to the Trión farm-out, on October 4, 2017, the National Hydrocarbons Commission held a bidding round for farm-outs of the Ogarrio, Cárdenas-Mora and Ayin-Batsil blocks. No bids were received for the Ayin-Batsil block, which is located in the shallow waters of the Gulf of Mexico. However, multiple bids were received for the Ogarrio block. The Ogarrio and Cárdenas-Mora blocks, both onshore fields located in the state of Tabasco, were awarded to the German company Deutsche Erdoel AG (DEA), which later formally changed its name to Wintershall Dea México, S. de R.L. de C.V., and the Egyptian company Cheiron Holdings Limited (Cheiron), respectively. DEA's bid consisted of an initial cash payment of U.S.$190.0 million, a royalty rate of 13% and an additional cash payment of U.S.$213.9 million, which is the highest sign-up bonus submitted in a National Hydrocarbons Commission bidding round as of the date of this annual report. Cheiron's bid consisted of an initial cash payment of U.S.$125.0 million, a royalty rate of 13% and an additional cash payment of U.S.$41.5 million. The contracts were signed on March 6, 2018 and have a term of 25 years. We retained a 50% interest in both blocks. The Ogarrio and Cárdenas-Mora fields are currently in the development stage following the approval of the development plan by the National Hydrocarbons Commission. In 2025, the Ogarrio field produced 3.3 thousand barrels of crude oil per day and 8.5 million cubic feet per day of natural gas. In 2025, the Cárdenas-Mora block produced 3.4 thousand barrels per day of crude oil and 9.9 million cubic feet per day of natural gas.

*Other Exploration and Extraction Contracts*

In addition to the farm-outs described above, we have also pursued other types of partnerships for the exploration and production of fields that were not granted to us.

On December 5, 2016, we participated in the bidding process referred to as Round 1.4, through which we, as part of a consortium consisting of Pemex Exploration and Production (our former subsidiary entity), Chevron Energía de Mexico, S. de R.L. de C.V., or Chevron Energía, a subsidiary of Chevron Corporation, and INPEX Corporation, were awarded an exploration contract for block 3 located in the Perdido Fold Belt in the Gulf of Mexico. The block covers an area of approximately 1,686.9 square kilometers and is located approximately 117 kilometers off the coast of Mexico in water depths ranging between 500 meters and 1,700 meters. Chevron Energía is the operator and holds a 33.334% interest in the consortium, while we and INPEX Corporation each hold a 33.333% interest. The corresponding exploration and extraction contract and joint operating agreement were executed in February 2017. The exploration plan was approved by the National Hydrocarbon Commission in March 2018. As of the date of this annual report, the consortium is in the process of relinquishing its interest in the block.

The Ek-Balam project area is in the Campeche Basin. Its production comes from Ek and Balam fields, specifically from the Upper Oxfordian sands and the Upper Cretaceous fractured carbonates.

On May 2, 2017, Pemex Exploration and Production (our former subsidiary entity) entered into a production-sharing contract with the National Hydrocarbons Commission to upgrade the assignments under the shared shallow water production concession structure for the Ek and Balam project area located in Campeche Basin. Within the framework of the contract, which has a term of 22 years with two possible five-year extensions, the Mexican Government will retain 70.5% of the operating profits and we will retain 29.5% of the operating profits, as long as there is a cost recovery carry forward. We provided a guarantee of U.S.$5.0 billion in connection with this contract. During 2025, we produced an average of 62.1 thousand barrels per day of crude oil and 14.3 million cubic feet per day of natural gas pursuant to such contract.

On June 19, 2017, we participated in another bidding round conducted by the National Hydrocarbons Commission, referred to as Round 2.1. As a result of this bidding process, we won two blocks. We were awarded Block 2, which covers an area of 549 square kilometers and is located on the continental shelf of the Tampico-Misantla basin, to the west of the Gulf of Mexico, in partnership with Wintershall Dea México, S. de R.L. de C.V. We are the operating partner in this block and own a 70% interest. Additionally, we were awarded Block 8, which is in the Southeastern Basins and covers an area of 586 square kilometers, in partnership with Colombia's Ecopetrol. In Block 8, we are also the operating partner and own a 50% interest. As part of its strategy to optimize its portfolio of exploration projects, Ecopetrol assigned its participation interest to us, and on November 15, 2022, the National Hydrocarbons Commission approved the exit of Ecopetrol from this project. The corresponding contracts for the exploration and extraction of hydrocarbons with Wintershall Dea México, S. de R.L. de C.V. and Ecopetrol were signed on September 25, 2017. The documentation reflecting Ecopetrol's exit from Block 8 is currently being finalized with the National Hydrocarbons Commission. Both blocks are in the exploration phase following approval of the exploration plans by the National Hydrocarbons Commission in November and October of 2018, respectively.

On December 18, 2017, we executed contracts in association with Petrofac México, S.A. de C.V., or Petrofac, under which we assigned to Petrofac the rights to certain fields that were part of the El Golpe-Puerto Ceiba project, including the onshore fields of Santuario and El Golpe located in the state of Tabasco. We have a 64% interest in this project. During 2025 we had an average production of 13.9 thousand barrels per day of crude oil and 19.4 million cubic feet per day of gas. These fields are currently in the development stage following approval of the development plan by the National Hydrocarbons Commission on April 28, 2022.

On March 2, 2018, we completed the first migration of an FPWC. The FPWC governing the Misión block was migrated to a shared production contract with Servicios Múltiples de Burgos, S.A. de C.V. and the National Hydrocarbons Commission. The Misión block is in the states of Nuevo León and Tamaulipas. We have a 51% interest in the contractual area and the average production under this contract in 2025 amounted to 26.7 million cubic feet per day of natural gas. The FPWC governing the Misión block allows exploration and extraction activities. The development and exploration plans approved by the National Hydrocarbons Commission were carried out December 2022 and April 2023, respectively. The Misión block is currently in both the exploration and extraction phases.

On March 27, 2018, we successfully participated in the first call of bidding Round 3 of the National Hydrocarbons Commission, and were awarded seven contractual areas in shallow waters, six of them as part of a consortium and one on an individual basis. Pemex Exploration and Production (our former subsidiary entity) was awarded four blocks in the Southeast Basins: two in consortium with Total S.A., one with Shell Oil Company and one individually, as well as three blocks corresponding to the province of Tampico-Misantla-Veracruz: two in partnership with Compañía Española de Petróleos and one in partnership with Wintershall Dea México, S. de R.L. de C.V.

We participated in another bidding round conducted by the National Hydrocarbons Commission, referred to as Round 2.4, obtaining four exploration blocks. On May 7, 2018, we signed four exploration and extraction contracts covering several deep-water blocks in the Gulf of Mexico, the rights to which were auctioned off pursuant to the bidding process:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.Block 2 with Shell Exploración y Extracción de México, S.A. de C.V., as operator. We have a 50% interest in the contractual area, which spans 2,146 square kilometers and is in the Plegado Perdido Belt.

The National Hydrocarbons Commission approved the exploration plans for Block 18 in August 2019, for Blocks 16 and 17 in September 2019 and for Blocks 29, 32, 33, 35 in October 2019. As of the date of this annual report these blocks are currently in the exploration phase.

On August 3, 2018, we migrated the Integrated E&P Contract for the Ébano block to a shared production contract with DS Servicios Petroleros, S.A. de C.V. (DIAVAZ), as operator, and D&S Petroleum, S.A. de C.V. The Ébano block spans an area of 1,569.1 square kilometers and is located in the states of Veracruz, San Luis Potosí and Tamaulipas. In 2025, average production under this contract amounted to 3.0 thousand barrels per day of crude oil and 1.3 million cubic feet per day of gas. We and DIAVAZ contributed to a corporate guarantee delivered to the Mexican Government in accordance with our respective interests in the partnership. The corporate guarantee amounted to U.S.$500 million, 45% of which was contributed by us and 55% of which was contributed by DIAVAZ.

Our shared production contract for the Ébano block allows for exploration and extraction activities. The National Hydrocarbons Commission approved the development plan in March 2023 and the exploration plan in October 2019. As of the date of this annual report, Ébano block is currently in both the exploration and extraction phases.

On September 18, 2018, we signed a pre-unitization agreement related to certain tracts of the Yaxché field and the Production Sharing Contract for Block 7 with a consortium of Talos Energy Offshore Mexico, as operator, Sierra Oil & Gas and Premier Oil. Both areas are located in the offshore regions of Mexico's Southeastern basins. This pre-unitization agreement was signed for two years and enabled information-sharing relating to the discovery of the Zama field, which spans Block 7 and a neighboring block assigned to us.

On November 21, 2018, we migrated the Integrated E&P Contract for the Miquetla block to a license contract with Operadora de Campos DWF, S.A. de C.V., as operator. The Miquetla block spans 139.7 square kilometers and is located in the states of Puebla and Veracruz. In 2025, average production under this contract was 0.7 thousand barrels per day of crude oil and 2.4 million cubic feet per day of natural gas. We have a 49% interest in the contractual area and the contract has a term of 30 years. Our license contract for the Miquetla block allows for exploration and extraction activities. The National Hydrocarbons Commission approved the development and exploration plans in November 2023. As of the date of this annual report, Miquetla block is currently in both the exploration and extraction phases.

On December 9, 2019, the Talos-led consortium submitted to the Ministry of Energy a shared reservoir notice for the Zama field. On March 5, 2020, the Ministry of Energy resolved to continue with the unitization process.

On May 21, 2020, based on the technical opinion of the National Hydrocarbons Commission, the Ministry of Energy determined that Zama is a shared field. Therefore, in accordance with current legislation, in July 2020, the Ministry of Energy instructed us and the "Block 7 Consortium" (Talos Energy Offshore Mexico 7, S. de R.L. de C.V., Sierra O&G Exploración y Producción, S. de R.L. de C.V. (now a Wintershall Dea company) and Premier Oil Exploration and Production Mexico, S.A. de C.V.) to carry out the unification of the Zama field, with the aim of maximizing the exploitation of this field for the benefit of Mexico. In response, we and the Block 7 Consortium continued with our discussions in order to jointly submit a proposed unitization agreement to the Ministry of Energy. In September 2020, we and the Block 7 Consortium decided to activate the expert's procedure outlined in the preliminary unitization agreement. On April 22, 2021, we and the Block 7 Consortium received the final expert report that defined the initial tract participation in the Zama reservoir. The final expert report determined that we hold 50.43% of the Zama reservoir whereas the Block 7 Consortium holds the other 49.57%.

We and the Block 7 Consortium were unable to reach an agreement with respect to the unitization of the Zama field. Therefore and in accordance with current legislation, the Ministry of Energy determined the terms and conditions of the unitization on March 22, 2022, via the document entitled Resolución de Unificación, Campo Zama (Unitization Resolution for Zama Field).

On July 22, 2021, the Ministry of Energy appointed Pemex Exploration and Production as the operator of Zama. On September 3, 2021, Talos submitted a dispute notification to the Ministry of Economy regarding the designation of Pemex Exploration and Production as the operator of Zama. Thus, considering that Talos has not started additional actions aimed to continue the dispute and according to the official term for the process, it is considered formally concluded.

On March 23, 2022, Pemex Exploration and Production received the Unitization Resolution of Zama Field issued by the Ministry of Energy. Pursuant to the resolution, Pemex Exploration and Production, as the unit operator, submitted to the National Hydrocarbons Commission the field development plan of the Zama Unit on March 23, 2023. On this regard, the operating committee of the Zama Unit comprised of Pemex Exploration and Production and the Block 7 Consortium Firms held three meetings to discuss and define relevant aspects of the field development plan of the unit. In addition, Pemex Exploration and Production and the Consortium undertook meetings to address technical issues related to field development, infrastructure, detailed engineering, industrial safety, among others. Thus, the plan was approved by the operating committee of the Zama Unit.

In accordance with the Unitization Resolution for Zama Field, on May 4, 2022, Pemex Exploration and Production submitted to the National Hydrocarbons Commission the Evaluation Report and the Declaration of Commercial Discovery for the Zama Field.

The field development plan for the Zama Unit was authorized by the National Hydrocarbons Commission on June 1, 2023. The plan contemplates the installation of two production platforms, the drilling and completion of 29 development wells and 17 injector wells, as well as infrastructure for conditioning and distribution of the oil and gas to be produced.

On September 26, 2023, our Board of Directors approved the business case for the Zama field, which contemplates an aggregate of Ps.92 billion in investments over the 2023-2054 time period.

In May 2024, a Systems, Applications, and Products in Data processing (SAP) system was implemented so the companies involved in the Zama Unit could open a banking account via an operative trust. Since July 2024, we have acted as unit operator and have issued cash calls for expenses incurred.

During 2024, we executed several technical studies and undertook various activities aimed at preparing the environmental impact statement at a regional level. Furthermore, some seismic acquisition feasibility studies were conducted and meetings were undertaken among the Technical Sub Committee members to discuss technical topics such as weight optimization for the future offshore infrastructure, selection of modular versus semi-submersible drilling rig and the production model optimization. Likewise, a Front-End Engineering Design (FEED) study contract was signed with a consortium lead by the Doris Group and was rescheduled to be concluded in April 2025 due to change orders.

In September 2025, we concluded a strategic review resulting in our decision to resign as unit operator. This decision was aimed at strengthening the goal of early production of the field, with the objective of starting initial oil production by late December 2027, in alignment with our Strategic Plan 2025-2035. Consequently, pursuant to the unitization resolution, we formally notified the unit operating committee of our intention to resign from the operator role. The Block 7 Consortium Firms, having accepted the resignation, thereafter presented a proposal for a substitute operator. Accordingly, on October 9, 2025, the three entities with participation in the Zama Unit submitted to the Ministry of Energy a joint request for the change of unit operator.

On December 30, 2025, we received the notification from the Ministry of Energy approving the appointment of Harbour Energy Unidad Zama, S. de R.L. de C.V. as the Zama Unit substitute operator. This approval included the corresponding modification to the Unitization Resolution for the Zama Field. The designation was granted after the substitute operator demonstrated its legal, financial, and technical capabilities, as well as its extensive experience and execution proficiency.

In parallel with the aforementioned process, on October 20, 2025, following the approval of the Operating Committee, we submitted a request to the Ministry of Energy the modification request of the Field Development Plan. This request is aligned with our early production goal and consists of two phases. The first phase is focused on producing first oil by late December 2027, and essentially involves a subsea production system comprising five wells equipped with wet Christmas tree connectors, a Floating Production Storage and Offloading (FPSO) vessel, and a gas pipeline. The second phase involves two platforms, the drilling of 21 development wells equipped with artificial lift by using electrical submersible pumping, a secondary recovery scheme via waterflooding including 15 injection wells and, a second FPSO vessel.

Jointly, the two stages of the project are projected to reach a peak production rate of 120 thousand oil barrels per day and 47 million cubic feet of gas per day. The total investment estimated for the project amounts to U.S.$12.2 billion. Currently, the modification request for the development plan is pending approval from the Ministry of Energy.

*Development of newly discovered fields*

In 2025, we worked to develop five onshore fields. We designed the following strategies for those developments:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• integrated services contract schemes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• regulatory, contractual and constructive simplification;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• establishing reference engineering;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• homologation of technical bases for design;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• special studies for updating integrated models;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reassessment of the development plan, increasing additional areas and the number of wells to be drilled; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cost reduction in field development.

**Industrial Processes and Energy Transformation (formerly Pemex Industrial Transformation)**

Prior to March 19, 2025, business activities now belonging to our Industrial Processes and Energy Transformation segments were operated through our former productive state-owned subsidiary, Pemex Industrial Transformation. Effective March 19, 2025, Pemex Industrial Transformation has been dissolved and all of the assets, liabilities, rights and obligations of Pemex Industrial Transformation have been assumed by Petróleos Mexicanos. For more information, see "*Special Note Regarding Mexican Energy Reform," "Item 4—Information on the Company—History and Development—Recent Energy Reform*" and Note 1 to our consolidated financial statements included herein. As a result of this change, the financial information that was previously reported for Pemex Industrial Transformation is now reported under our Industrial Processes and Energy Transformation segments.

<u>Industrial Processes (formerly a segment of Pemex Industrial Transformation)</u>

Our Industrial Processes segment generates revenue from the sale of refined petroleum products and their derivatives, most of which are sold to third parties in the domestic market. This market also supplies the CFE with a significant portion of its fuel oil for electricity production and provides jet fuel to Airports and Auxiliary Services, a state-owned administrator of airport services in Mexico. The most important refined products are gasoline, diesel and jet fuel.

<u>Energy Transformation (formerly a segment of Pemex Industrial Transformation)</u>

Our Energy Transformation segment generates revenue from domestic sales, primarily of natural gas, liquefied petroleum gas, naphtas, butane, ethane and certain other petrochemicals, such as methane, ethane, aromatics, ammonia and fertilizers, as well as their derivatives.

The Industrial Processes segment's main activities are (i) refining processes and (ii) the production of petrochemicals (including ethylene and its derivatives, fertilizers and ammonia, aromatics and methanol), while the Energy Transformation segment is responsible for the processing of natural gas and the production of natural gas liquids and certain associated petrochemicals. The cash-generating units associated with each of these activities are described in Note 12-F to our consolidated financial statements included herein.

***a)*** *Refining Processes*

Our refining production processes include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Atmospheric distillation*. This process heats crude oil in a tube furnace at atmospheric pressure to distill refined products. The primary products produced are gasoline, jet fuel, diesel, atmospheric gas oil and atmospheric residual crude oil.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Vacuum distillation*. This process heats crude oil or other feedstock in a vacuum distillation column, which is operated at low pressures. The objective of this process is to maximize production of heavy vacuum gas oil, which is produced by boiling crude oil.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Cracking.* This process uses either heat and pressure or a catalytic agent to increase gasoline yields from crude oil.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Visbreaking*. This is a thermal cracking process, which uses a horizontal-tube heater brought to a high temperature. Visbreaking reduces flasher bottom viscosity and produces some heavy gas oil.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Reforming processes*. These processes use heat and catalysts to transform smaller or unstable hydrocarbon molecules into larger, more useful refining or blending products. For example, we use reforming processes to convert low octane gasoline into higher octane stocks that are suitable for blending into finished gasoline and to convert naphthas into more volatile, higher octane products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Hydrotreatment or residual hydrocracking*. This process uses a catalyst and hydrogen at high temperature and pressure to remove sulfur, nitrogen and some aromatic compounds. Hydrotreatment also processes some lighter liquid product off-take. The new processes also include the saturation of aromatic compounds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Alkylation and isomerization*. This polymerization process unites olefins and isoparaffins. Butylenes and isobutanes are combined with sulfuric acid or hydrofluoric acid to rearrange straight-chain hydrocarbon molecules into branched-chain products. Pentanes and hexanes, which are difficult to reform, are isomerized through the use of aluminum chloride and other precious-metal catalysts. Normal butane may be isomerized to provide a portion of the isobutene feed needed for the alkylation process. The process produces a high octane, low sensitivity blending agent for gasoline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Coking*. This process is a severe method of thermal cracking used to upgrade heavy residuals into lighter products or distillates. Coking produces straight-run gasoline (coker naphtha) and various middle-distillate fractions used as catalytic feedstock, thus generating a concentrated solid material.

These production processes together constitute our production capacity as set forth in the table below.

*Source: Petróleos Mexicanos Infrastructure (Oil Facilities under the Industrial Processes segment).* 

As of December 31, 2025, we owned and operated seven refineries in Mexico: Cadereyta, Madero, Minatitlán, Olmeca, Salamanca, Salina Cruz and Tula. The refining process begins in crude distillation units, where crude oil received is separated into primary fractions based on their different boiling ranges. These streams are then incorporated into subsequent stages of the process within the hydrodesulfurization, catalytic cracking, catalytic reforming, alkylation, and other conversion and treatment units. The integrated operation of these processes optimizes fuel quality, reduces sulfur content, increases the production of higher-value products, and ensures compliance with applicable environmental and commercial specifications.

During 2025, crude oil processing of the National Refining System averaged 1,013.8 thousand barrels per day, an increase of 108.2 thousand barrels per day, or 11.9%, compared to the 905.6 thousand barrels per day in 2024. This

increase was mainly as a result of the strategy implemented by Pemex to strengthen and consolidate the operational continuity of the country's refineries. It should be noted that in February 2025, the Olmeca refinery began continuous operations, with a progressive increase in processing levels throughout the year, coupled with the partial start-up of the delayed coker unit facilities in Tula in July 2025, which allowed for an increase in crude oil processing volume and the production of higher value-added products.

***Production***

We produce a wide range of products derived from crude oil and natural gas, including liquefied petroleum gas, gasoline, jet fuel, diesel, fuel oil, asphalts, lubricants, among other refined products. In 2025, we produced 1,022.1 thousand barrels per day of refined products (including dry gas, a by-product of the refining process), an increase of 11.9% compared to the 913.7 thousand barrels per day in 2024.

The following table sets forth, by category, our production of petroleum products for the five years ended December 31, 2025.

The volume of our domestic gasoline sales increased by 0.9% in 2025, from 668.1 thousand barrels per day in 2024 to 674.1 thousand barrels per day in 2025. Of our domestic gasoline sales, Pemex Magna sales were 517.0 thousand barrels per day, a decrease of 1.7% compared to 525.5 thousand barrels per day in 2024, and Pemex Premium sales were 156.7 thousand barrels per day, an increase of 10.2% compared to 142.2 thousand barrels per day, and Aviation Fuels sales remained flat at 0.4 thousand barrels per day.

The volume of our domestic diesel sales decreased by 4.7%, from 289.2 thousand barrels per day in 2024 to 275.7 thousand barrels per day in 2025. This volume does not consider intercompany sales, which averaged 10.5 thousand barrels per day in 2024 and 7.4 thousand barrels per day in 2025.

The volume of our domestic sales of fuel oil increased by 1.3%, from 59.1 thousand barrels per day in 2024 to 59.9 thousand barrels per day in 2025, primarily due to upper sales to the Federal Electricity Commission ("CFE").

We have implemented the following actions to bolster national petroleum products' sales: strengthening Pemex's commercial presence through branded commercial schemes suitable for customers; guarantee of product availability nationwide; bonuses and incentives; creation of value for customers and establishing loyalty programs. These efforts resulted in domestic sales recovery.

As of December 31, 2025, there were 7,480 Pemex retail service stations in Mexico, 7,435 were privately owned and operated as franchises, while the remaining 45 were owned by Pemex. This total number of retail service stations represents an increase of 2.9% compared to the 7,266 service stations as of December 31, 2024, mainly due to the expansion of operations. Moreover, out of the 7,480 service stations with a franchise contract, 5,955 were operating converted to the new corporate identity.

Additionally, as of the end of December 2025, Pemex delivered petroleum products to 4,308 service stations with mixed supply. Likewise, 1,155 service stations operate under a Trademark Use License (LUM) for Pemex products.

As part of its commercial strategy, Pemex operates through wholesale and retail channels, both branded and unbranded. In the case of unbranded schemes, product purchases are made through a marketing contract in which, depending on the case, it is possible to obtain better prices and credit conditions. For branded customers, both marketers and associated distributors can sell products under the Pemex brand.

Despite the aggressive competitive environment, Pemex maintained a 58.2% market share with franchised and licensed service stations at the end of December 2025.

In March 2025, Pemex concluded with the implementation of the 7S generation of the performance additive "Aditec" in 100% of the domestic terminals. This additive includes a molecular tracer that makes it possible to identify the authenticity of Pemex Magna and Premium gasolines sold at Franchise and LUM service stations.

In 2025, petrochemical sales recorded a significant increase compared to 2024. This was driven by the start of operations of the Olmeca refinery, which boosted the production of propylene and sulfur.

Overall, by the end of 2025 there were 987 marketing contracts in place. Of this total, 292 correspond to gasoline and transportation fuels, and 695 to industrial products and fuels.

*Pricing Regulations* 

Fuel prices in Mexico were liberalized on December 31, 2017. However, the CRE had the authority to intervene with the regulated markets. Effective March 19, 2025, the CRE was dissolved and its duties, rights and obligations were assumed by the new National Energy Commission (the "CNE"). Existing agreements, reports, resolutions and other declarations by the CRE will remain in effect until they are repealed, amended, or replaced by CNE. For more information, see "*Special Note Regarding Mexican Energy Reform" and "Item 4—Information on the Company—History and Development—Recent Energy Reform*."

Our retail sales prices (final consumer prices) can be subject to potential future regulations by the National Energy Commission and the Ministry of Energy, such as the case of retail sales prices of LPG.

Through agreements A/030/2018 and A/022/2019, the CRE abrogated the asymmetric regulation of Pemex Industrial Transformation (now dissolved) with respect to the commercialization of natural gas.

On March 19, 2025, the Hydrocarbons Sector Law came into effect, introducing a new regulatory framework applicable to the hydrocarbons sector. As part of these changes, the first-hand sale regime was eliminated and replaced by commercialization agreements, under which prices are determined under market conditions in accordance with the new applicable regulatory provisions.

Under the applicable legal regime, the retail prices of gasoline and diesel in Mexico are not subject to formal government price controls and are determined by market conditions. Retail prices may nonetheless be affected by

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

governmental measures and by voluntary arrangements with the Mexican Government entered into by fuel retailers, including us. In February 2025, we and certain private fuel retailers entered into a voluntary agreement with the Mexican Government that established a maximum retail price of regular gasoline, which has subsequently been renewed, including in the first quarter of 2026. In April 2026, the Mexican Government and the fuel retailers extended this agreement to also maintain the price of diesel. Although these arrangements are voluntary and do not constitute formal mandatory price controls under Mexican law, they stabilize retail prices for regular gasoline and diesel for participating retailers. For more information, see*"Risk Factors—Risks Related to our Relationship with the Mexican Government—The Mexican Government has historically imposed, and may in the future impose, price controls or other pricing measures in the domestic market on our products."*

On January 1, 2026, in accordance with reports issued by the CNE, average national regular retail gasoline prices decreased by Ps.0.02 per liter, as compared to December 2025. Similarly, the average national retail price of diesel decreased by Ps.0.01 per liter on January 1, 2026, as compared to December 2025.

*Fuel Oil* 

On November 3, 2017, the CRE authorized new formulas to determine the price of fuel oil. After the entry of the reform to the Hydrocarbons Sector Law, the regulations applicable to first-hand sales were eliminated through an agreement issued by the CNE on October 6, 2025. In accordance with the current regulatory framework, fuel oil prices are now determined under commercialization agreements in accordance with applicable regulatory provisions. These prices are calculated weekly and apply to all customers.

We withhold IEPS tax. While it is included in the price to our customers, we pay this tax to the authorities upon collection of the sale of our products and it is not included in our revenues. For more information, see "*—Taxes, Duties and Other Payments to the Mexican Government—Fiscal Regime for PEMEX*."

As of January 1, 2025, the *IEPS a los Combustibles Fósiles* (IEPS Tax on Fossil Fuels) was 22.16 Mexican cents per liter and as of January 1, 2026, the IEPS Tax on Fossil Fuels was 23.00 Mexican cents per liter.

*Natural Gas* 

Since July 1, 2017, third parties have been permitted to participate in the domestic natural gas market. Prior to March 19, 2025, we sold natural gas under two separate pricing structures. Under the first-hand sale price, we sold natural gas directly to customers at injection points, without the use of transportation or additional services. Under the full marketing price, we sold natural gas at customer plants, with the price of the molecule including transportation and services costs associated with the commercialization of natural gas. Under the current framework, we sell natural gas under commercialization agreements, pursuant to which we charge the price of the molecule together with the transportation and other service costs associated with the commercialization of natural gas.

Liquefied *Petroleum Gas* 

From December 16, 2019 to March 18, 2025, market list prices were established in accordance with the LPG pricing mechanisms approved by the *Comité de Precios y Aspectos Económicos de la Política Comercial de Petróleos Mexicanos* (Committee on Prices and Economic Aspects of the Commercial Policy of Petróleos Mexicanos) in compliance with Resolution RES/1008/2019 of the former CRE, which considered our participation in first-hand sales and the marketing of LPG within a free market.

Since March 19, 2025, when the 2025 Petróleos Mexicanos Law came into force, our LPG pricing mechanisms are authorized by the Board of Directors of Petróleos Mexicanos.

As of January 1, 2025, the IEPS Tax on Fossil Fuels was 20.00 Mexican cents per kilogram. As of January 1, 2026, the IEPS Tax on Fossil Fuels was 21.00 Mexican cents per kilogram.

We withhold IEPS tax. For more information, see "—*Taxes, Duties and Other Payments to the Mexican Government—Fiscal Regime for PEMEX*."

The Mexican Government could modify these price controls or impose additional price controls in the future. See "*Item 3—Key Information—Risk Factors—Risk Factors Related to our Relationship with the Mexican Government—The Mexican Government has historically imposed, and may in the future impose, price controls or other pricing measures in the domestic market on our products*"

Since July 29, 2021, the LPG retail sales price (final user's price) is regulated by the CNE, formerly CRE, pursuant to the *Directriz de emergencia para el bienestar del consumidor de gas licuado de petróleo* (Emergency directive for the welfare of the liquified petroleum gas consumer) issued by the Ministry of Energy, with the purpose of protecting the end users.

*Refining's Capital Expenditures and Budget Investments* 

We continue to focus on maintaining our existing refineries and expanding the National Refining System to increase petroleum products production. We continue to aim to stabilize and improve our ability to process heavy crude oil to optimize our refinery production and increase our production of other hydrocarbons to supply growing national demand. In addition, we focused our investment program on the coking unit projects at the Tula and Salina Cruz refineries through the execution of the residual use projects, with the aim of improving the performance of higher value-added petroleum products, as well as enhancing the quality of gasoline and diesel we produce to achieve Mexico's environmental standards.

Our refining business invested Ps.35,621 million in capital expenditures in 2025 and has budgeted Ps.26,873 million in capital expenditures for 2026.

A focus of our refining capital expenditures program is the rehabilitation of the National Refining System. Pursuant to the rehabilitation program, we have evaluated each of our seven existing Mexican refineries and have identified specific maintenance requirements for each unit. Our rehabilitation program focuses on addressing critical risks to the facilities such as mechanical integrity and safety and improving the efficiency and the stabilization of our crude oil processing.

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

regard, from September 2019 to December 2025, major and minor repairs have been carried out at various facilities within the National Refining System, mainly in primary distillation units, combined units, viscosity-reducing units, coker units, catalytic cracking, de-asphalting units, catalytic reforming units, methyl tertiary-butyl ether (MTBE), Tert-Amyl Methyl Ether (TAME) units, alkylation units, isomerization units, gasoline hydrotreaters, and intermediate distillates ultra-low sulfur gasoline (ULSG), hydrogen, and sulfur recovery unit, as well as in facilities within the utilities area and storage tanks. During 2025, 64 repairs were completed at processing units: 4 major repairs and 60 minor repairs. The National Refining System rehabilitation program will continue to be implemented during 2026.

Since 2019, Petróleos Mexicanos has been implementing the rehabilitation program, which aims to help stabilize operations through the repair and maintenance of six refineries: Cadereyta, Madero, Minatitlán, Salamanca, Salina Cruz, and Tula. This rehabilitation program aims to address critical risks at the facilities, restore asset reliability, and contribute to improving efficiency and stabilizing the crude oil processing. Since the introduction of this program in early September 2019 through December 31, 2025, we completed 96 major repairs and 423 minor repairs in process units, 36 major repairs and 281 minor repairs in main services and 46 major repairs and 83 minor repairs in storage tanks.

In 2026, the National Refining System will work to increase the efficiency and reliability of refining processes through the continuation of the Maintenance and Rehabilitation Program.

***Olmeca Refinery in Dos Bocas, Paraíso, Tabasco***

As a result of the strategy implemented by Petróleos Mexicanos to strengthen and consolidate the operational continuity of the country's refineries by improving the reliability of the processing units, the first processing train at the Olmeca refinery began operations in February 2025 and the second train in May of that same year, and they operated continuously with a gradual increase in processing levels throughout the year. Construction and start-up projects for the Olmeca refinery have concluded and the Olmeca refinery has been fully operational since February 2025.

*Hydrogen Fuel Supply for Refineries* 

On December 29, 2023, an executive decree was published in the Official Gazette of the Federation designating the supply of hydrogen from the U-3400 hydrogen plant at the Miguel Hidalgo refinery in Tula de Allende, Hidalgo to be in the public interest.

Pursuant to the decree, Pemex Industrial Transformation temporarily took over the plant's operations and was responsible for compensating the former operators of the plant in connection with the public interest declaration and as required by applicable law. The former operators initiated two administrative actions challenging the temporary occupation decree; the first has been resolved, while the second, related to the amount of compensation, remains pending.

On February 8, 2024, an executive decree was published in the Official Gazette of the Federation designating the U-3400 hydrogen plant as a public utility to be transferred to Pemex Industrial Transformation.

On April 18, 2024, an executive decree was published in the Official Gazette of the Federation, leaving the December decree without effect and transferring the U-3400 hydrogen plant to Pemex Industrial Transformation. Pursuant to the April decree, Pemex Industrial Transformation permanently assumed ownership of the plant's property, assets and operations and became responsible for covering the indemnification owed to the plant's former operators based on an appraisal conducted by Mexico's *Instituto de Administración y Avalúos de Bienes Nacionales* (INDAABIN), which valued the relevant assets at Ps. 319.4 million.

On April 25, 2024, in accordance with applicable law, an executive decree was published in the Official Gazette of the Federation giving legal notice to the plant's former owners, Air Liquide Mexico, S. de R. L. de C.V. ("Air Liquide"), stating that any claims had to be submitted to the relevant government ministry within fifteen business days. Air Liquide initiated an administrative action against the expropriation decree, and subsequently filed a second administrative action challenging the amount of compensation (INDAABIN's appraisal), both of which remain pending as of the date of this annual report.

As of December 31, 2024, the transfer of the U-3400 hydrogen plant to Pemex Industrial Transformation was complete. This transfer did not result in a material increase in our assets.

Further, on April 7, 2025, Air Liquide International S.A., the parent company of Air Liquide, commenced arbitration proceedings against the Mexican Government with the International Centre for Settlement of Investment Disputes (ICSID) for the expropriation of the U-3400 hydrogen plant, alleging that the Mexican Government violated international treaties on foreign investment. An ICSID tribunal was constituted on March 9, 2026, and the first arbitration session was held on April 21, 2026. As of the date of this annual report, this dispute remains pending.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b) Ethylene and Derivatives**

The objectives of our ethylene and derivatives line of business include the production, distribution and marketing of ethane and propylene derivatives. In 2025, we produced a total of 527.8 thousand tons of petrochemical products, a 12.2% decrease from the 600.9 thousand tons produced in 2024. This decrease was primarily due to lower availability of ethane.

The Ethylene and Derivatives business line produces several petrochemical products, including:

In 2025, the Cangrejera and Morelos petrochemical complexes together produced 248.3 thousand tons of ethane derivatives, 1.5 thousand tons of propylene and propylene derivatives; and 278.0 thousand tons of other products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Pajaritos Refrigerated Ethylene Shipping Terminal*: We have previously used this terminal for the import

of ethane. No ethane was imported in 2024 and 2025. In 2023, we imported 5.8 thousand tons of ethane through this terminal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Arenque*. This facility contains three units that, in total, produced 20.2 million cubic feet per day of dry gas in 2025.

In addition, our Industrial Processes segment operates the Coatzacoalcos Gas Processor Complex, which is treated as a separate cash-generating unit for impairment testing purposes (see Note 12-F to our consolidated financial statements included herein). The Morelos, Cangrejera, Independencia and Pajaritos petrochemical complexes referenced elsewhere in this Item 4 are also operated by our Industrial Processes segment but are tested as separate cash-generating units from the Coatzacoalcos Gas Processor Complex; certain natural gas liquids streams from these petrochemical complexes are

reported within our consolidated natural gas liquids production. In 2025, our Industrial Processes segment contributed approximately 2.6 thousand barrels per day of natural gas liquids from the Cangrejera and Morelos petrochemical complexes.

*Petrochemical Complexes* 

In addition to our gas processing facilities, we also own the following two petrochemical complexes operated by our Industrial Processes segment:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Independencia*. The Independencia petrochemical complex consists of two units and is located in the Central region. In 2025, this complex produced 139.4 thousand tons of methanol in its first unit and 3.4 thousand tons of petrochemical specialties in its second unit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Cangrejera*. The Cangrejera petrochemical complex consists of five units and an aromatics line and is located in the Southern region. In 2025, this complex produced 666.7 thousand tons of aromatics and derivatives, as well as 395.8 thousand tons of other petrochemical products (butanes, BTX liquids, hydrogen, pentanes and petroleum products, such as gas naphtha and heavy naphtha).

In 2025, we processed 2,144.9 million cubic feet per day of wet natural gas, of which 1,916.6 million cubic feet per day was sour wet gas and 228.4 million cubic feet per day was sweet wet gas. This figure represents an 7.5% decrease compared to the 2,318.9 million cubic feet per day processed in 2024, primarily due to lower availability of wet natural gas from the Exploration and Extraction segment in the amount of approximately 173.9 million cubic feet per day less than the previous year.

We process sour and sweet condensates from our Exploration and Extraction segment to obtain stabilized natural gas liquids and recover liquid hydrocarbons from the sweet natural gas processing stream. In addition, we obtain liquids from internal streams and hydrocarbons condensed in sour wet gas pipelines. Our production of natural gas liquids, including stabilized condensates, reprocessing, and other fractionation streams, decreased by 16.6% from 151.6 thousand barrels per day in 2024 to 126.5 thousand barrels per day in 2025. This decrease was mainly due to lower availability of wet natural gas from the Exploration and Extraction segment.

We process sour condensates, which have a higher sulfur content, to produce stabilized sweet condensates. In 2025, the volume of sour condensates we processed, along with internal streams from the Gas business line, totaled 7.3 thousand barrels per day, a 34.3% decrease compared to the 11.1 thousand barrels per day recorded in 2024. We also process sweet condensates at the Burgos facilities to produce heavy and light natural gasoline. In 2025, we processed 1.1 thousand barrels per day of sweet condensates, a 28.9% decrease compared to the 1.5 thousand barrels per day processed in 2024. This decrease was mainly attributed to a lower supply of sweet condensates from our Exploration and Extraction segment.

*Pro-Agroindustria, S.A. de C.V.* 

In 2014, we acquired a non-operating nitrogen fertilizer production facility located in Pajaritos, Veracruz. After the acquisition, we initiated a major rehabilitation project that involved the restoration of our rotating, static and mechanical equipment and the rehabilitation of a carbon dioxide compression station and pipelines for its transportation. The rehabilitation was focused on the two urea plants and was completed in 2018; however, none of the plants could be commissioned at the time. Urea production started in November 2020 at our Urea 1 plant.

In 2025, total annual urea production was 213,788 tons, an increase of 45% compared to the 147,914 tons of urea produced in 2024. This increase was mainly due to three factors: a) operational availability of both urea plants, b) greater availability of raw materials for production, as well as c) ongoing major maintenance work carried out at Urea Plant I and other projects, which has provided greater operational reliability.

As of the date of this annual report, both Urea plants are operating at up to 80% capacity. During 2026, production is expected to reach 600,000 tons, subject to the availability and supply of raw materials. The Urea 1 and Urea 2 plants will have a combined production capacity of up to 990,000 tons of urea per year once they are operating at full capacity.

There was an increase of 20.2% in the production of phosphate products compared to 2024. This increase was mainly due to the recovery of capacity at the Lázaro Cárdenas complex, as well as the establishment of a maquila contract which led to longer operating windows to continue infrastructure maintenance. Additionally, there was a 7.4% decrease in the production of nitrogen products in 2025 compared to 2024, mainly due to a decrease in low-density nitrate production, resulting from the contraction in the country's mining industry due to the cancellation of concessions and strikes at some sites. Overall phosphate and nitrate production capacity increased by 42.1% compared to 2024, mainly due to the increase in available operating days compared to the previous year, when maintenance activities reduced operating days.

Production of other products decreased by 81.2% in 2025 compared to 2024. This category consists of intermediate products that are marketed as part of a cost-containment strategy or to take advantage of downtime at the granulation plants. The decrease in 2025 was primarily due to a decrease in sulfuric acid exports of 232.4 thousand metric tons; in 2025, 100% of the sulfuric acid produced was consumed internally in the production of phosphates, and incremental production was curtailed to contain operating costs, primarily as a result of elevated sulfur costs. This was partially offset by a 13.2% increase in finished product output (phosphates and nitrates), from 659.1 thousand tons in 2024 to 745.8 thousand tons in 2025.

Sales in the phosphate and nitrogen product lines increased by 15.2% and 22.1%, respectively, in 2025 compared to 2024, mainly due to the increase in the volume traded and, to a lesser extent, to the increase in the selling prices of finished products from 2024 to 2025.

In terms of sales by market, the same trend was observed in 2025 as in 2024, with sales in the national market prevailing over sales in foreign markets. In 2025, the distribution of sales in the national market compared to foreign markets increased, reaching 85.2%, compared to 81.5% in 2024, of total sales in the domestic market and 14.8%, compared to 18.5% in 2024, in the foreign market, with sales in the national market being 21.7% higher in 2025 versus 2024. Such increase in sales to the domestic market, as well as the decrease in foreign markets, was mainly due to the limitation in the volume of sales in foreign markets caused by the decrease in imports volume of finished products to sell in foreign markets and increased sales to the Mexican Government for the *Fertilizantes para el Bienestar* ("Fertilizers for Welfare") program.

In 2025, our global average operational production capacity was 68.5%, a decrease compared to the 79.6% production capacity registered in 2024. This decline was primarily driven by increased downtime across production units during fiscal year 2025. Capacity utilization is expected to improve upon completion of the ongoing investment projects in the production units, which are designed to increase output capacity and reduce downtime.

Before 2025, initiatives and projects were developed with funds given by Pemex Industrial Transformation (which was dissolved on March 19, 2025, with its assets, liabilities, rights and obligations assumed by Petróleos Mexicanos) with the objective of recovering the productive capacity of Grupo Fertinal, S.A. de C.V., by increasing production volumes and reducing production costs in the coming years. Operational improvements and cash flow management allowed Grupo Fertinal, S.A. de C.V. to continue advancing in the capacity recovery program using resources from its operations during fiscal year 2025.

Since 2019, Grupo Fertinal, S.A. de C.V. has participated in the Mexican Government's Fertilizers for Welfare program pursuant to which it distributes DAP and urea fertilizer products to rural communities in Mexico. In 2025, Grupo Fertinal, S.A. de C.V. distributed 1,150 thousand metric tons of fertilizer under this program.

Collaboration and Other Agreements

On March 24, 2020, we entered into a technological and scientific collaboration agreement with the *Secretaría de Agricultura y Desarrollo Rural* (Ministry of Agriculture and Rural Development, or "SADER") for Grupo Fertinal, S.A. de C.V. to carry out activities to support the acquisition, supply and distribution of fertilizers and the provision of technical, legal and human resources within the Fertilizers for Welfare program until September 30, 2024. Such agreement is non-commercial and there is no transfer of resources among the parties. In 2024, we amended and extended the collaboration agreement with SADER until 2046. Grupo Fertinal, S.A. de C.V. will continue its participation in the Fertilizers for Welfare Program during fiscal year 2026.

*Deer Park Refining Limited Partnership* 

Deer Park's core activity is the sale of refined products to third parties.

*Refining Processes and Capacity* 

Our refining production processes include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Atmospheric distillation*. This process heats crude oil in a tube furnace at atmospheric pressure to distill refined products. The primary products produced are gasoline, jet fuel, diesel, atmospheric gas oil and atmospheric residual crude oil.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Vacuum distillation*. This process heats crude oil or other feedstock in a vacuum distillation column, which is operated at low pressures. The objective of this process is to maximize production of heavy vacuum gas oil, which is produced by boiling crude oil.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Cracking*. This process uses either heat and pressure or a catalytic agent to increase gasoline yields from crude oil.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Reforming processes*. These processes use heat and catalysts to transform smaller or unstable hydrocarbon molecules into larger, more useful refining or blending products. For example, we use reforming processes to convert low octane gasoline into higher octane stocks that are suitable for blending into finished gasoline and to convert naphtha into more volatile, higher-octane products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Hydrotreatment or residual hydrocracking*. This process uses a catalyst and hydrogen at high temperature and pressure to remove sulfur, nitrogen and some aromatic compounds. Hydrotreatment also processes some lighter liquid product off-take. The new processes also include the saturation of aromatic compounds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Alkylation*. This polymerization process unites olefins and isoparaffins. Butylenes and isobutanes are combined with sulfuric acid or hydrofluoric acid to rearrange straight-chain hydrocarbon molecules into branched-chain products. Pentanes and hexanes, which are difficult to reform, are isomerized using aluminum chloride and other precious-metal catalysts. Normal butane may be isomerized to provide a portion of the isobutene feed needed for the alkylation process. The process produces a high octane, low sensitivity blending agent for gasoline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Coking*. This process is a severe method of thermal cracking used to upgrade heavy residuals into lighter products or distillates. Coking produces straight-run gasoline (coker naphtha) and various middle-distillate fractions used as catalytic feedstock, thus generating a concentrated solid material.

These production processes together constitute our production capacity as set forth in the table below.

**Logistics Operations (formerly Pemex Logistics)** 

Prior to March 19, 2025, our Logistics segment operated through the productive state-owned subsidiary Pemex Logistics and provided land, maritime and pipeline transportation, as well as storage and distribution services, to certain of our subsidiaries, local gas stations and distributors. Effective March 19, 2025, in connection with the enactment of the 2025 Petróleos Mexicanos Law, Pemex Logistics has been dissolved and all of its assets, liabilities, rights and obligations were assumed by Petróleos Mexicanos. Pursuant to our New Organic Statute, logistics activities are now conducted through our Logistics Operations business line as part of our Other Operating Subsidiary Companies segment. For more information, see "*Special Note Regarding Mexican Energy Reform" and "Item 4—Information on the Company—History and Development—Recent Energy Reform."*

*Transportation of Crude Oil and Refined Products*

During 2025, we injected 1,535.6 thousand barrels per day of crude oil and petroleum products into our pipelines, representing a 7.9% decrease as compared to 2024, when we injected 1,667.0 thousand barrels per day, primarily due to a decrease in crude oil processing at the Madero, Minatitlán and Salamanca refineries.

During 2025, we injected 114.9 thousand barrels per day of LPG, representing an 11.6% decrease as compared to the 130.0 thousand barrels per day of LPG injected in 2024, primarily due to lower transportation and delivery requirements in our Industrial Processes segment at terminals and interconnections associated with the LPG pipeline transportation system. Additionally, we injected 5.0 thousand barrels per day of petrochemicals in 2025, an increase of 117.4% as compared to the 2.3 thousand barrels per day we injected in 2024. This increase was mainly driven by higher demand for isobutane at the Minatitlán and Salina Cruz refineries.

In 2025, we transported a total of 2,350.9 thousand barrels per day of petroleum products, of which 1,655.5 thousand barrels per day (70.4%) were transported through pipeline systems, 454.7 thousand barrels per day (19.4%) were transported by land (381.5 thousand barrels per day by tank truck and 73.2 thousand barrels per day by tank car) and the remaining 240.7 thousand barrels per day (10.2%) were transported by tankers.

*Treatment and Primary Logistic* 

In 2025, we received an average of 1,175.2 thousand barrels per day of crude oil for treatment, which consists of dehydration and desalination, representing a decrease of 1.3% as compared to 1,190.4 thousand barrels per day in 2024. This decrease was primarily due to lower crude oil deliveries from our Exploration and Extraction segment. During the

same period, we transported an average of 1,091.7 thousand barrels of crude oil per day to the National Refining System, through Nuevo Teapa and TASP Pajaritos and 198.7 thousand barrels of crude oil were delivered to the export terminals.

During 2025, we transported an average of 2,583.1 million cubic feet per day of non-processed natural gas through the Altamira, Misión, Santuario and Gas Marino Mesozoico transportation systems, representing a 4.3% decrease compared to the 2,700.5 million cubic feet per day in 2024, primarily due to lower availability of unprocessed natural gas shipments from our Exploration and Extraction segment. In addition, we transported an average of 13.1 thousand barrels per day of condensate through the Misión and Condensado Terrestre Sur transportation systems, representing 12.1% decreased compared to 14.9 thousand barrels per day in 2024, primarily due to lower product availability from our Exploration and Extraction segment.

During 2025, we recorded 36 leak and spill events (16 in pipelines and 20 in industrial installations), one of which had a moderate impact, meaning that less than 10m<sup>3</sup> of product was spilled and the affected area was less than 10,000m<sup>2</sup>, while the remaining events were not considered significant.

*Open Season* 

Since 2017, under the guidelines issued by the CRE, Pemex Logistics (our former subsidiary entity) began participating in "Open Season" auctions, which are intended to be transparent and competitive auctions for access to our pipelines and storage infrastructure, wherein any participant can compete to offer its services.

In line with our new legal regime as a public state-owned company under the Energy Reform Decree, the Secondary Legislation now prioritizes our participation in the domestic hydrocarbons industry. As part of this change, the Hydrocarbons Sector Law repealed the prior Hydrocarbons Law and eliminated the open access obligations that had applied to pipeline transportation, storage and distribution infrastructure. Accordingly, as of the date of this report, we are no longer subject to the Open Season mechanism for such infrastructure. For more information, see "*Special Note Regarding Mexican Energy Reform*" and "*Item 4—Information on the Company—History and Development—Recent Energy Reform*."

*Transport and Distribution* 

Our pipelines connect crude oil and natural gas production centers with refineries and petrochemical plants, as well as with our storage terminals located in Mexico's major cities. At the end of 2025, the pipeline network measured approximately 17,361.2 kilometers in length, of which 13,367.5 kilometers are currently in operation and 3,993.7 kilometers are temporarily out of service due to lower production in the field where such pipeline is located or because the transportation service is irregular, which makes its use unprofitable. Once circumstances are more favorable, the pipeline's status is changed to operational. As of the date of this annual report, we are analyzing 3,535.9 kilometers of the 3,993.7 kilometers of pipelines that are temporarily out of operation to determine potential alternatives for their future use.

As of December 31, 2025, our pipeline network was distributed as follows:

---

| | |
|:---|:---|
| **<u>Transported Product</u>** | **Length (km)** |
| Petroleum products | 8301.2 |
| Crude Oil | 5237.2 |
| LP Gas | 1477.9 |
| Chemicals | 309.8 |
| Petrochemicals | 1824.4 |
| Fuel Oil | 130.5 |
| Jet Fuel | 80.2 |
| **Total** | **17361.2** |

We implemented a management plan for pipeline devices, which requires maintaining detailed documentation of pipeline conditions to optimize investments focused on maintenance. The pipeline integrity management plan is based on what is established in Chapter IV of the "General Administrative Provisions that support the Guidelines on Industrial Safety, Operational Safety and Environmental Protection, for land transport by means of Oil, Petroleum and Petrochemical

Pipelines" (DAGs), taken in turn from NOM-027-SESH-2010, as well as API RP 1160 standards for liquid hydrocarbons, and contemplates the following stages:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.collection of detailed logs and the development of a pipeline database;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.categorization and identification of threats that could affect integrity, safety and operation of pipelines;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.identification of critical points in the pipeline;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.risk assessment of the reliability and integrity of pipelines;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.planning and scheduling of maintenance and risk mitigation; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.continuous monitoring throughout all stages.

We have made considerable progress towards meeting the General Administrative Provisions that establish the guidelines on the DAGs requirements on risk assessment and pipeline integrity described in Chapter VI of the DAGs. As of December 31, 2025, we have analyzed 100% of our network of logistics pipelines. The risk and integrity analyses are conducted on a yearly basis, in order to keep all the integrity management plans updated. In addition, we have implemented several measures related to our pipeline integrity management plan, including by collecting information to create pipeline databases.

The results of our risk evaluation are as follows:

---

| | | |
|:---|:---|:---|
| High Risk | 0.0 | kilometers |
| Medium Risk | 8,626.2 | kilometers |
| Low Risk | 8,735.0 | kilometers |

Although we maintain a pipeline integrity management strategy focused on the integrity and operation of our transportation pipeline systems, we recorded 99 leaks and spills in 2025, compared to 92 incidents recorded in 2024.

The transportation of crude oil, liquefied petroleum gas and other products through the pipeline network is subject to various risks, including risk of leakage and spills, explosions and fuel theft. In 2025, we spent a total of Ps.471.1 million for the rehabilitation and maintenance of our pipeline network, and we have budgeted Ps.2,489.1 million for these expenditures in 2026. This increase in budgeting was primarily due to greater availability of financial resources, which allowed us to expand rehabilitation and maintenance activities across our pipeline network. See "*Item 3—Key Information—Risk Factors—Risk Factors Related to our Operations—We are an integrated oil and gas company and are exposed to production, equipment and transportation risks, criminal acts, blockades to our facilities and deliberate acts of terror that could adversely affect our business, results of operations and financial condition*" and "*—Business Overview—Environmental Liabilities*" above.

*Fleet Developments* 

In July of 2013, as part of a plan to modernize our fleet, we signed an agreement with the *Secretaría de Marina Armada de México* (Mexican Navy, or "SEMAR"), valued at Ps.3,212.1 million (U.S.$250.0 million), for the construction of 22 vessels for Pemex Industrial Transformation, which formally operated through Pemex Refining. This agreement initially included construction of 16 tugboats, three multipurpose vessels and three barges, but was amended in 2016 to remove the construction of the three barges and to extend the final delivery date to January 2022. On March 26, 2021, the Mexican Navy and Petróleos Mexicanos agreed to reduce of the scope of the agreement in two supply orders. This transaction is now valued at Ps.5,052 million. As of December 31, 2025, of the 19 vessels contemplated under the amended scope of the agreement, two remain retained by the Mexican Navy as compensation for outstanding amounts related to services received by us. Of the remaining 17 vessels committed for delivery, 16 have been delivered and one is pending delivery, scheduled for completion during the first four months of 2026.

As of December 31, 2025, we owned 16 refined product tanker vessels. We also have 21 tugboats, three supplier vessels, 1,800 tanker trucks and 369 tanker cars, as well as 73 storage and distribution terminals, 11 liquefied gas terminals, five maritime terminals and 11 dock operation and maintenance facilities. These facilities, together with our pipeline network, constitute the hydrocarbons transportation and distribution infrastructure.

As of December 31, 2025, our fleet of refined product tankers included 16 vessels, all owned by us, with a transportation capacity of 5,000 thousand barrels per day. Of these vessels, 37.5% are located on the Pacific coast and the other 62.5% in the Gulf of Mexico. In the Pacific coast, 85.6% of total capacity is allocated to the transportation of distillates, while 14.4% is used for fuel oil and heavy diesel. In the Gulf of Mexico, 81.3% of total transport capacity is allocated to distillates and 18.7% to fuel oil and heavy diesel.

*Logistics Capital Expenditures and Budget*

Our Logistics Operations business line invested Ps.5,372.0 million in capital expenditures in 2025 and has budgeted Ps.8,954.0 million in capital expenditures for 2026.

The following table sets forth our Logistics Operations business line's capital expenditures, excluding non-capitalizable maintenance, for each of the three years ended December 31, 2023, 2024 and 2025, as well as the budget for 2026. Capital expenditure amounts are derived from our budgetary records, which are prepared on a cash basis. Accordingly, these capital expenditure amounts do not correspond to capital expenditure amounts included in our consolidated financial statements prepared in accordance with IFRS.

*Centro Nacional de Control del Gas Natural (CENAGAS)* 

Pursuant to the Hydrocarbons Law, on August 11, 2014, CENAGAS was created as a decentralized public entity of the Mexican Government to act as the independent administrator of the Integrated Natural Gas System. This system interconnects the infrastructure for the storage and transportation of natural gas across the nation, with the aim of expanding coverage, strengthening security measures and improving the continuity, quality and efficiency in transportation service.

In 2025, we provided operation and maintenance services at four CENAGAS compression stations and two CENAGAS regulation and measurement stations for which we obtained compensation in the amount of Ps.120 million.

**International Trading** 

PMI and the PMI Subsidiaries conduct international commercial activities for our crude oil, refined and petrochemical products, with the exception of natural gas, which is marketed directly by us. The PMI Subsidiaries' main objectives are to assist in maximizing our profitability and optimizing our operations through international trade. The PMI Subsidiaries facilitate our link with international markets and pursue new business opportunities by marketing PEMEX's required or produced products internationally. PMI and the PMI Subsidiaries manage the international sales of our crude oil and petroleum products and acquire in the international markets the petroleum products required to satisfy domestic demand. Sales of our crude oil are carried out through PMI. Trading of petroleum products in the international markets is carried out through P.M.I. Trading DAC, which also performs third-party trading, transportation and risk management activities in alternative markets (customers and suppliers other than us).

*Exports and Imports* 

As of December 31, 2025, PMI purchased crude oil from our Exploration and Extraction segment and then sold it to PMI's customers. PMI sold an average of 580.6 thousand barrels of crude oil per day in 2025, which represented 35.9% of our total crude oil production, inclusive of condensed crude oil production and exclusive of amounts produced in conjunction with other partners.

The following tables set forth the composition and average prices of our crude oil exports for the periods indicated.

tbpd = thousand barrels per day.

API gravity refers to the specific gravity or density of liquid petroleum products, measured in degrees on the American Petroleum Institute ("API") scale. On the API scale, oil with the lowest specific gravity has the highest API gravity. In addition, holding all other factors constant, the higher the API gravity, the greater the value of the crude oil.

<sup>(1)</sup> After being suspended in 2017, exports of Olmeca crude oil resumed in 2023.

<sup>(2)</sup> Includes Mexican Blend Salina Cruz (MXB SC) crude oil. Due to the increase in light and super light crude oil production, and the need expressed by Pemex, MXB SC crude oil began to be exported in March 2023.

<sup>(3)</sup> As of September 2023, MXB SC crude oil became known as "Zapoteco" crude oil, by its own price formula approved by the Board of Directors.

<sup>(4)</sup> During 2023, 2024 and 2025, we did not export Talam crude oil.

Tbpd = thousand barrels per day.

API gravity refers to the specific gravity or density of liquid petroleum products, measured in degrees on the API scale. On the API scale, oil with the lowest specific gravity has the highest API gravity. In addition, holding all other factors constant, the higher the API gravity, the greater the value of the crude oil.

<sup>(1)</sup> After being suspended in 2017, exports of Olmeca crude oil resumed in 2023.

*Source: PMI operating statistics as of December 31, 2025.*

In total, we exported 580.6 thousand barrels of crude oil per day in 2025. We sell crude oil produced by us under a variety of contractual arrangements. We believe that our proved developed and proved undeveloped reserves will be sufficient to allow us to fulfill our supply commitments.

The following table sets forth the average volume of our exports and imports of crude oil, natural gas and petroleum products for the five years ended December 31, 2025.

Crude oil exports decreased by 28.0% in 2025, from 806.1 thousand barrels per day in 2024 to 580.6 thousand barrels per day in 2025 mainly due to a lower availability of crude oil by Pemex and from increased crude oil processing and consumption by the National Refining System. We did not export Olmeca crude oil during 2021 and 2022, due to a lack of availability of Olmeca crude oil for export. However, in July 2023, the export of this type of crude in the international market resumed. In March 2023, the Mexican Blend Salina Cruz (MXB SC) crude began to be exported and, as of September 2023, it became known as "Zapoteco" crude oil, with its own price formula approved by the Board of Directors.

We import dry gas, a variety of natural gas, to complement our production and to meet demand in areas of northern Mexico that, due to their distance from the fields, can be supplied more efficiently by importing natural gas from the United States. In 2025, we imported 843.1 million cubic feet per day of natural gas, an increase of 14.3% compared to the 737.7 million cubic feet per day we imported in 2024. This increase was mainly due to higher self-consumption of gas due to the consolidation of operations of the Olmeca Refinery.

In 2025, our imports of liquefied petroleum gas increased by 1.9% compared to 2024. Meanwhile, the value of our liquefied petroleum gas imports decreased by 0.4% due to reference prices.

PMI Trading buys and sells both refined products and petrochemical products, primarily under the following terms: Free on Board (FOB), Delivered at Frontier (DAF), Delivered Ex Ship (DES), Delivered at Place (DAP) and Cost and Freight (CFR).

*Source: Pemex BDI.*

In 2025, exports of petroleum products decreased by 21.5%, from 225.3 thousand barrels per day in 2024 to 176.8 thousand barrels per day in 2025, mainly due to lower export volumes of (natural) gasoline and fuel oil. Imports of the main petroleum products declined by 17.2%, from 680.6 thousand barrels per day in 2024 to 563.7 thousand barrels per day in 2025, primarily because of lower import volumes of gasoline and diesel.

Exports of petroleum products decreased in value by 32.1% in 2025, in comparison with 2024, primarily due to lower volumes and lower reference prices. In 2025, imports of petroleum products decreased in value by 26.6%, also reflecting lower reference prices and lower import volumes.

The Secretary of Energy did not enter into any further agreements to reduce or increase crude oil exports and production, during 2024 and 2025. See "*Item 4—Information on the Company—Trade Regulation, Export Agreement and Production Agreements*" below.

*Hedging Operations*

Certain PMI Subsidiaries have implemented a regulatory framework for risk management with respect to its activities, which consists of policies, guidelines and procedures to manage the market risk associated with its commodity trading activities in accordance with industry best practices, such as: 1) the use of derivative financial instruments (DFIs) for financial risk mitigation purposes; 2) the segregation of duties; 3) valuation and monitoring mechanisms, such as the generation of a daily portfolio risk report, value at risk ("VaR") computation; and 4) VaR limits, both at a global and business unit level and the implementation of stop loss mechanisms. See "*Item 11—Quantitative and Qualitative Disclosures About Market Risk*."

*Gas Stations in the United States* 

In 2025, there were a total of 25 service stations operating under the PEMEX licensing agreement program in the United States, five in the state of Texas and 20 in the state of California. The fuel supply at these gas stations is derived from the United States wholesale market, and the retail selling prices are subject to the local market conditions in the locations of each service station.

We are evaluating an updated commercial strategy, taking into consideration the current market conditions, including fuel demand and brand positioning and recognition, to adapt to consumer needs within each region, align with our strategic objectives and maximize market penetration and brand value in subset markets.

Our insurance covers risks of sudden and accidental physical damage to or destruction of our properties, as well as risk of sudden and accidental physical loss, including as a consequence of purposeful terrorist acts and sabotage. This insurance also provides coverage for the contents of pipelines, storage facilities and packaged products, and any of our liabilities arising from such acts. Our insurance also covers extraordinary costs related to the operation of offshore wells, such as control and re-drilling costs, evacuation expenses and liability costs associated with spills. We also maintain protection and indemnity insurance for our full marine fleet, in addition to life insurance for employees, automobile and heavy equipment insurance, cargo and transportation insurance, as well as insurance against all risks in construction for minor works or assemblies on assets in operation and insurance to protect against illegal acts.

In accordance with Mexican law, we have entered into all of our insurance contracts with Mexican insurance carriers. These policies have limits of U.S.$1.8 billion for onshore property including the entire Deer Park facilities, U.S.$1.9 billion for offshore property, U.S.$0.3 billion for extraordinary costs related to the operation of offshore wells, U.S.$1.1 billion for onshore and offshore liabilities, U.S.$0.5 billion for offshore terrorist acts and U.S.$0.5 billion for onshore terrorist acts, plus U.S.$1.0 billion for liabilities associated with the operation of vessels.

Limits of insurance policies purchased for each category of risk are determined using professional risk management assessment surveys conducted by international companies on an annual basis and the market capacity available per risk. In addition, in compliance with the regulations enacted in June 2016 by the ASEA, we maintain insurance coverage with respect to third party liability, liability for environmental damage and control of wells, works or drilling activities, extraction of hydrocarbons, the treatment and refining of crude oil and the processing of natural gas. We have also ensured that we maintain insurance coverage in connection with our strategic alliances and other joint arrangements.

Since 2003, we purchase ad hoc business interruption mitigation insurance coverage, which compensates us for the additional expenses necessary to recover our production capabilities in the shortest time possible.

All of our insurance policies are reinsured through IKAL Insurance Company AG (which we refer to as IKAL and was formerly Kot Insurance). IKAL is a wholly owned subsidiary company that was originally formed in 1993 under the laws of Bermuda as Kot Insurance Company, Ltd. and was subsequently organized under the laws of Switzerland in 2004. IKAL is used as a risk management tool to structure and distribute risks in the international reinsurance markets. IKAL reinsures policies held through our local insurance carriers and maintains control over the cost and quality of the insurance covering our risks.

IKAL reinsures over 80% of its reinsurance policies with unaffiliated third party reinsurers. IKAL carefully monitors the financial performance of its reinsurers and actively manages counterparty credit risk across its reinsurance portfolio to ensure its own financial stability and creditworthiness. IKAL maintains solid capitalization and solvency margins consistent with guidelines provided by Swiss insurance authorities and regulations. As of December 31, 2025, IKAL's net risk retention is approximately U.S.$615 million spread across different reinsurance coverages to mitigate potential aggregation factors.

*Compliance at Pemex* 

Our current corporate compliance program, *Pemex Cumple* (Pemex Complies), was authorized by the Board of Directors of Petróleos Mexicanos in June 2023. This program amended and supplemented our previous compliance program, which the Board of Directors of Petróleos Mexicanos approved on November 16, 2019. See "*Item 4 – General Regulatory Framework*" for more information regarding Pemex Complies.

This program aims to promote a culture of ethics and compliance with applicable national and international laws, treaties, and regulations specific to the oil and gas sector. It is structured around four pillars: (i) Ethics and Integrity, (ii) Anti-Corruption, (iii) Legal Compliance and (iv) Transparency and Protection of Personal Data. The program seeks to implement various strategies and lines of action to build trust in commercial relationships with third parties and society at large. The General Counsel of Petróleos Mexicanos provides annual progress reports to the Board of Directors of Petróleos Mexicanos and semiannual reports to the Sustainability Committee concerning the implementation of Pemex Complies.

To enhance and guide the implementation of the Pemex Complies program, the Board of Directors of Petróleos Mexicanos approved an amendment to the Organic Statute of Petróleos Mexicanos on April 27, 2021. This amendment was published in the Official Gazette of the Federation on May 7, 2021. It strengthens certain existing functions and introduces new responsibilities for the Legal Department of Petróleos Mexicanos, aligning them with those typically handled by a compliance officer in accordance with international best practices. This effort is managed by the Legal Management of Legal Compliance. Our current Organic Statute of Petróleos Mexicanos, approved in 2025, preserves the provisions introduced by the 2021 amendment, ensuring continuity, institutionalization, and alignment with the company's integrity, risk prevention, and regulatory compliance objectives.

With the above modifications, the Pemex Complies program is continuously being improved, thus strengthening the measures aimed at preventing, reducing and mitigating acts of theft, fraud and corruption, and maintaining adequate and effective control and surveillance systems, which constantly and periodically monitor compliance with our integrity standards and with the regulatory and legal provisions that are applicable to us.

**Property, Plants and Equipment**

*General*

Substantially all of our property, consisting of refineries, storage, production, manufacturing and transportation facilities and certain retail outlets, is located in Mexico, including Mexican territorial waters in the Gulf of Mexico, except for facilities related to the Deer Park refinery, which are located in the state of Texas in the United States of America. The location, character, utilization and productive capacity of our exploration, drilling, refining, petrochemical production, transportation and storage facilities are described above. See "—*Exploration and Extraction*," "*—Industrial Transformation*" and "*—Logistics and Strategic Safeguard*" in this Item 4. The insurance program covering all of our properties is also described above under "—*Insurance*."

*Reserves*

Under the Mexican Constitution, all crude oil and other oil and gas reserves located in the subsoil of Mexico are owned by Mexico and not by us. The Mexican Government has granted us the right to extract, but not own, petroleum and other oil and gas reserves in areas that have been assigned to us by the Ministry of Energy pursuant to the Hydrocarbons Sector Law. Other companies participating in the Mexican oil and gas industry may report assignments or contracts and the corresponding expected benefits for accounting and financial purposes. See "*Information on the Company—History and Development—Legal Regime*" above in this Item 4. Our estimates of hydrocarbons reserves are described under "—*Exploration and Extraction—Reserves*" above.

**GENERAL REGULATORY FRAMEWORK** 

We are regulated by the Mexican Constitution, the 2025 Petróleos Mexicanos Law and the Hydrocarbons Sector Law, among other regulations. The purpose of the 2025 Petróleos Mexicanos Law is to regulate the organization, management, operation, monitoring, evaluation and accountability of Petróleos Mexicanos as a state-owned public company of the Mexican Government. On December 3, 2025, the Regulations to the 2025 Petróleos Mexicanos Law were published in the Official Gazette of the Federation. The purpose of these regulations is to regulate, among other things, the appointment and removal of the members of the Board of Directors of Petróleos Mexicanos, potential conflicts of interest for Board members, and the evaluation of Petróleos Mexicanos as well as the requirements and documentation applicable to independent board members, the rights and responsibilities of Board members, including their alternates, and the organization and operation of the Board of Directors and its committees. For more information on recent changes to our

regulatory framework, see "*Special Note regarding Mexican Energy Reform*" and "*History and Development—Recent Energy Reform*" in this Item 4.

The Mexican Government and its ministries regulate our operations in the oil and gas sector. The Ministry of Energy monitors our operations, and the Secretary of Energy acts as the chairperson of the Board of Directors of Petróleos Mexicanos. In addition, the *Ley de la Comisión Nacional de Energía* (National Energy Commission Law), published in the Official Gazette of the Federation on March 18, 2025, repealed the *Ley de los Órganos Reguladores Coordinados en Materia Energética* and establishes the powers of the National Energy Commission, including the issuance of technical, administrative and operational resolutions; the granting, amendment, update, revocation and termination of permits, authorizations and other administrative acts; and the regulation of applicable consideration, prices and tariffs. The Ministry of Energy has the authority to award and execute contracts for exploration and production. The National Energy Commission has the authority to grant permits for the storage, transportation and distribution of oil, gas, petroleum products and petrochemicals in Mexico, and to regulate the first-hand sale of these products. The regulatory powers of the Ministry of Energy, and the National Energy Commission extend to all oil and gas companies operating in Mexico, including us. For more information, see "*History and Development--Recent Energy Reform—New Legal Regime—Hydrocarbons Sector Law and the Law of the National Energy Commission*."

Following the publication in the Official Gazette of the Federation on March 18, 2025 of the 2025 Petróleos Mexicanos Law, Petróleos Mexicanos' special regime now comprises matters relating to affiliate entities; compensation and austerity; procurement, leases, services and public works; assets; administrative liabilities; budget and accounting; and debt and sustainability. On October 8, 2021, the General Provisions for Contracting with Petróleos Mexicanos and its Productive State-Owned Subsidiaries were published in the Official Gazette of the Federation. These General Provisions regulate the legal process for acquisitions, leases, works and services needed for our projects and require that our suppliers, contractors and other participants with whom we have or intend to have a commercial relationship have compliance programs, or adhere to our *Código de Ética para Petróleos Mexicanos, sus empresas productivas subsidiarias y empresas filiales* (Code of Ethics for Petróleos Mexicanos, its subsidiary entities and affiliates, or the Code of Ethics) and our *Código de Conducta de Petróleos Mexicanos, sus empresas productivas subsidiarias y, en su caso, empresas filiales* (Code of Conduct of Petróleos Mexicanos, its subsidiary entities and, where applicable, affiliated companies, or the Code of Conduct), which are part of our compliance program, with the signed commitment to implement their own compliance program, as well as having programs or systems for prevention and compliance with the legal provisions and applicable to the development of its operations, activities or services. In addition, a due diligence process is conducted to any third party with whom we intend to enter into and/or continue with a commercial agreement prior to the execution of the agreement. Notwithstanding the foregoing, in certain cases, provisions that refer to the former productive state-owned subsidiary entities remain in force under the current legal regime, despite the terminology used therein.

In accordance with the 2025 Petróleos Mexicanos Law, each year the Ministry of Finance and Public Credit provides us with estimated macroeconomic indicators for the following fiscal year, which we are to use to prepare the annual budget for Petróleos Mexicanos, including our financing program. Upon approval by the Board of Directors of Petróleos Mexicanos, our budget and financing program is then submitted to the Ministry of Finance and Public Credit, which has the authority to adjust our financial balance goal and the ceiling on our wage and salary expenditures for the fiscal year. The consolidated annual budget and financing program of Petróleos Mexicanos, including any adjustments made by the Ministry of Finance and Public Credit, is then incorporated into the federal budget for approval by the Chamber of Deputies. The Mexican Government is not, however, liable for the financial obligations that we incur. In approving the federal budget, the Chamber of Deputies authorizes our financial balance goal and the ceiling on our wage and salary expenditures for the fiscal year, which it may subsequently adjust at any time by modifying the applicable law.

We are also subject to various domestic and international laws and regulations related to anti-corruption, anti-bribery, anti-money laundering and anti-terrorist financing, such as the *Código Penal Federal* (Federal Criminal Code), which criminalizes certain corrupt practices, including bribery, embezzlement and abuse of authority; the *Ley General del Sistema Nacional Anticorrupción* (General Law of the National Anti-Corruption System); the *Ley* de *Fiscalización* y *Rendición de Cuentas de la Federación* (Federal Audit and Accountability Law) and the Ley General de Responsabilidades Administrativas (General Law of Administrative Liabilities), among others. These laws establish a national anti-corruption system designed to coordinate efforts among the Mexican Government, federal entities, states and municipalities to prevent, investigate and punish corrupt activities and oversee public resources, as well as determine administrative liabilities of public officials and the applicable penalties.

We also employ internal control procedures and guidelines designed to monitor the activities of our employees, including senior management, and to ensure compliance with applicable anti-corruption, anti-bribery, anti-money

laundering and anti-terrorist financing laws and regulations. The *Lineamientos que regulan el sistema de control interno en Petróleos Mexicanos, sus empresas productivas subsidiarias y empresas filiales* (Guidelines governing the internal control system of Petróleos Mexicanos, its productive subsidiary entities and affiliates) set forth the principles underlying our internal controls system and the procedures necessary for its implementation and monitoring. In addition, the *Lineamientos para regular a los Testigos Sociales en Petróleos Mexicanos y sus empresas productivas subsidiarias* (Guidelines to regulate public witnesses in Petróleos Mexicanos and its productive subsidiary entities), delineates how public witnesses may function as third-party observers in connection with our procurement procedures. These internal controls and guidelines apply to Petróleos Mexicanos. For a description of the risks relating to anti-corruption, anti-bribery and anti-money laundering laws and regulations, see "*Item 3—Key Information—Risk Factors—Risk Factors Related to our Operations—We are subject to Mexican and international anti-corruption, anti-bribery, anti-money laundering or similar laws. Our failure to comply with these laws could result in penalties, which could harm our reputation and have an adverse effect on our business, results of operations and financial condition.*"

On June 27, 2023, the Board of Directors of Petróleos Mexicanos amended our Pemex Complies program to reinforce existing strategies and lines of attention. The program aims to strengthen our compliance culture and prevent corruption and financial, reputational and legal risks, among others, with respect to Mexico's national anti-corruption strategy and applicable law. See "*— Compliance at Pemex*" in this Item 4 for more information.

On November 11, 2019, our Code of Conduct, was published in the Official Gazette of the Federation, replacing the Code of Conduct issued on August 28, 2017. Our Code of Conduct delineates behaviors expected of and banned for our executive officers and employees, in accordance with the values established in our Code of Ethics, and includes data protection, transparency, environmental conservation and social responsibility related matters. See "*Item 16B—Code of Ethics*" for more information regarding our code of ethics.

Our Code of Ethics was approved by the Board of the Directors of Petróleos Mexicanos on November 26, 2019, and published in the Official Gazette of the Federation on December 24, 2019. Our Code of Ethics includes the following principles and values: respect, non-discrimination, honesty, loyalty, responsibility, legality, impartiality and integrity. See "*Item 16B—Code of Ethics*" for more information regarding our Code of Ethics.

On July 21, 2021, the *Políticas y Lineamientos Anticorrupción para Petróleos Mexicanos, sus empresas productivas subsidiarias y, en su caso, Empresas Filiales* (Anti-corruption Policies and Guidelines for Petróleos Mexicanos, its productive subsidiary entities and, where applicable, affiliated companies) and the *Políticas y Lineamientos para el desarrollo de la Debida Diligencia en Petróleos Mexicanos, sus empresas productivas subsidiarias y, en su caso, Empresas Filiales, en Materia de Ética e Integridad Corporativa* (Policies and Guidelines to carry out Due Diligence in Petróleos Mexicanos, its productive subsidiary entities and, where applicable, affiliated companies, in Ethics and Corporate Integrity Matters) were updated and published in the Official Gazette of the Federation. The Policies and Guidelines to carry out Due Diligence in Petróleos Mexicanos, its productive subsidiary entities and, where applicable, affiliated companies, in Ethics and Corporate Integrity Matters were updated three times and the most recent update was published in the Official Gazette of the Federation on May 17, 2023. The purpose of these regulations is to set up actions to prevent acts of corruption, as well as provide means for executives' officers and employees to identify, manage, and mitigate corruption risks that may affect the attainment of our objectives or our involvement in illicit acts of any kind.

On June 15, 2020 and January 1, 2021, the *Políticas y Lineamientos para la Protección de Datos Personales en Petróleos Mexicanos, sus empresas productivas subsidiarias y, en su caso, Empresas Filiales* (Data Privacy Protection Policies and Guidelines for Petróleos Mexicanos, its productive subsidiary entities and, where applicable, affiliated companies) and the *Políticas y Lineamientos para el Cumplimiento de Obligaciones de Transparencia y Acceso a la Información Pública en Petróleos Mexicanos, sus empresas productivas subsidiarias y, en su caso, Empresas Filiales* (Policies and Guidelines to comply Transparency and Public Access Information duties in Petróleos Mexicanos, its productive subsidiary entities and, where applicable, affiliated companies) became effective, respectively. These regulations aim to create a framework for data privacy protection and promote transparency, accountability and public access in respect of our operations. In addition, the policies seek to provide resources for executives and employees to identify, manage, mitigate and address risks related to corruption, corporate integrity, transparency or the effects of any type of illicit activity.

As an issuer of debt securities that are registered under the Securities Act and in connection with certain representations and covenants included in our financing agreements, we must comply with the U.S. Foreign Corrupt Practices Act, or the FCPA. The FCPA generally prohibits companies and anyone acting on their behalf from offering or making improper payments or providing benefits to government officials to obtain or keep business. In addition, we are

subject to other international laws and regulations related to anti-corruption, anti-bribery and anti-money laundering. These include the U.S. Foreign Extortion Prevention Act, which makes it a crime for foreign government officials to demand or accept anything of value or for another person to influence the performance of an official act or otherwise confer an improper advantage, as well as the U.K. Bribery Act 2010, which prohibits the solicitation of, the agreement to receive and the acceptance of bribes.

**ENVIRONMENTAL REGULATION&nbsp;&nbsp;&nbsp;&nbsp;**

*Legal Framework*

We are subject to various environmental laws and regulations associated with atmospheric emissions, water usage and wastewater discharge, as well as waste management and care for affected sites. In particular, we are subject to the provisions of the *Ley General del Equilibrio Ecológico y la Protección al Ambiente* (General Law on Ecological Equilibrium and Environmental Protection or the "Environmental Law") and related regulations, the *Ley General para la Prevención y Gestión Integral de los Residuos* (General Law on Waste Prevention and Integral Management), the *Ley General de Cambio Climático* (the "General Law on Climate Change") and other environmental standards issued by the *Secretaría del Medio Ambiente y Recursos Naturales* (Ministry of the Environment and Natural Resources or "SEMARNAT"), the *Comisión Nacional del Agua* (National Water Commission, or "CONAGUA"), the Mexican Navy, the Ministry of Energy and the ASEA, as well as the latest update of NOM-001-SEMARNAT-2021, which establishes the permissible limits of pollutants in wastewater discharges into receiving water bodies.

In April 1997, SEMARNAT issued regulations governing the procedures for obtaining an environmental license, under which new industrial facilities can comply with all applicable environmental requirements through a single administrative procedure. Each environmental license integrates all of the different permits, licenses and authorizations related to environmental matters for a particular facility. Since these regulations went into effect, we have been required to obtain an environmental license for any new facility, in addition to environmental impact and risk authorizations required by SEMARNAT.

ASEA is a decentralized administrative body of SEMARNAT that operates with technical and administrative autonomy and has the authority to regulate and supervise companies participating in the hydrocarbons sector through its issuance of rules establishing safety standards and guidelines for the dismantling and abandonment of facilities, among other things. The *Ley de la Agencia Nacional de Seguridad Industrial y de Protección al Medio Ambiente del Sector Hidrocarburos* (Law of the Hydrocarbons Industrial Safety and Environmental Protection Agency of the Hydrocarbon Sector) provides that until the general administrative provisions and Official Mexican Standards proposed by the ASEA are in effect, obligations will continue under the guidelines, technical and administrative arrangements, agreements and Official Mexican Standards promulgated by SEMARNAT, the Ministry of Energy and the CNE. Effective March 19, 2025, the Ministry of Energy assumed certain of the regulatory powers previously exercised by the National Hydrocarbons Commission, and the CNE assumed certain of the powers previously exercised by the CRE, both of which were extinguished on that date. For more information, see "*Item 4—Information on the Company—History and Development—Recent Energy Reform—New Legal Regime*.".

We are also subject to the NOM-001-SEMARNAT-2021, published in March 2022 and in effect as of March 2023, which establishes the permissible limits of pollutants in wastewater discharges into public waters, the NOM-052-SEMARNAT-2005, which regulates hazardous waste, as well as the NOM-138-SEMARNAT/SSA1-2012, which establishes the maximum permissible levels of hydrocarbons in the soil and sets forth guidelines with respect to soil testing and the treatment of sites affected by hydrocarbon production, among other regulations.

In 2025, certain environmental regulations were amended, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• General administrative provisions establishing the Industrial Safety, Operational Safety and Environmental Protection Guidelines for the simultaneous retail sale of petroleum products and/or natural gas;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• General administrative provisions establishing the Industrial Safety, Operational Safety and Environmental Protection Guidelines for the land transportation by pipeline of crude oil, petroleum products and petrochemicals.

Likewise, in 2025, the ASEA issued the following Mexican official standards in this area:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• NOM-020-ASEA-2024, Transportation of natural gas through land pipelines (which supersedes NOM-007-ASEA-2016):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• NOM-019-ASEA-2024, Natural gas processing facilities (which supersedes NOM-137-SEMARNAT-2014).

Federal authorities are authorized to inspect any facility to determine its compliance with the Environmental Law, state environmental laws, regulations and technical official standards, as well as administrative provisions established by the ASEA in environmental matters. Violations or non-compliance with environmental standards and regulations may result in substantial fines, temporary or permanent shutdown of a facility, required capital expenditures to minimize the effect of our operations on the environment, cleanup of contaminated soil and water, cancellation of a concession or revocation of an authorization to carry out certain activities and, in certain cases, criminal proceedings. See "*Item 3—Key Information—Risk Factors—Risk Factors Related to Climate Change—Environmental regulations, including those aimed at mitigating climate change, could result in material adverse effects on our results of operations*."

Mexico participates in multilateral negotiations on climate change to promote a sustainable and low-carbon economy. In September 2016, the Mexican Government ratified the Paris Agreement and endorsed its Nationally Determined Contribution (NDC) by unconditionally committing Mexico to the reduction of 22.0% of its greenhouse gas emissions and 51.0% of its black carbon emissions (a short-lived climate pollutant) with respect to its 2013 baseline projected to 2030. This commitment may also be increased by an additional reduction of up to 36.0% of Mexico's greenhouse gas emissions and 70.0% of its black carbon emissions, on a conditional basis, subject to international financing, innovation and technology transfer, and if other countries, mainly major emitters, make efforts commensurate with the more ambitious targets of the Paris Agreement.

Achieving the targets set forth in Mexico's NDC requires the participation of all social and economic segments of the country, especially the energy and industrial sectors. As a result, in July 2018, the second transitory article of the General Law on Climate Change was amended to include the commitments undertaken by the Mexican Government. Pursuant to the General Law on Climate Change, greenhouse gas emissions from the oil and gas sector are required to decrease by 14.0% by the year 2030, as compared to the sector's baseline projection from 2013. In 2022, Mexico increased its unconditional commitment, raising its proposed Greenhouse Gas ("GHG") emissions reduction from 22.0% to 35.0% by 2030, compared to the initial scenario, and with a conditional target by up to 40.0% GHG reduction subject to further global agreements. For the oil and gas sector, the 14.0% reduction target remains, as set in the General Law on Climate Change.

As a result of the COP26, Mexico joined the Global Methane Pledge in order to participate in the efforts aimed at reducing the emissions that contribute to global warming and setting a 30% reduction commitment of its anthropogenic methane emissions by 2030, compared to those registered in 2020.

Additionally, Article 94 of the General Law on Climate Change was supplemented to indicate that SEMARNAT must gradually and progressively establish a national emissions trading system, designed to promote the reduction of emissions at the lowest possible cost. Pursuant to this law, the reduction of emissions must be measurable, reportable and verifiable. The *Programa de Prueba del Sistema de Comercio de Emisiones* (Pilot Program for the Emissions Trading System) is a pilot phase that has been operating since 2020 to ease the transition for system participants until the environmental authorities finalize the evaluation and assessment of the applicable regulations for its operational phases. During this pilot phase, we have been evaluating and actively participating in initiatives to reduce our emissions, taking into consideration the additional benefit that its implementation will have once emissions caps are defined for each participant.

In Mexico, regulations are generally reviewed every five years, and we work with the Mexican Government to update and develop new environmental regulations of activities related to the hydrocarbon industry through the National Consultative Committee for Environmental and Natural Resources Standardization and the National Advisory Committee for Standardization of Industrial and Operational Safety and Environmental Protection of the Hydrocarbons Sector.

In addition, the ASEA is empowered to issue general administrative provisions that regulate activities in the sector. The most important of these are the guidelines on industrial safety, operational safety, and environmental protection. In compliance with these guidelines, we have implemented the *Anexo de Seguridad, Salud y Protección Ambiental* (Safety, Health and Environmental Protection System, or "SSPA System"), which comprises various process safety management subsystems, including occupational health and environmental management. These elements are audited every two years by an external auditor, providing assurance to the ASEA that we meet the applicable regulatory requirements.

**Climate Change**

We are working to develop and implement a series of projects and initiatives to advance the fulfillment of our emissions goals for our main productive activities. In 2025, our operations in Mexico generated approximately 68.8 million tons of carbon dioxide equivalent, and our operations in Deer Park generated approximately 3.0 million tons. This represented an increase of 17.8% as compared to our total carbon dioxide equivalent emissions in 2024 (as measured by Scope 1 GHG emissions). The main factors contributing to this change include a substantial increase in operations at the Olmeca Refinery, the gradual start-up of plants in refineries and operational deviations in the cogeneration facilities supplying steam to gas processing operations, which are intended to improve performance in the short term.

In 2025, considering the relevance of climate change and our commitment to this issue, we took the following actions and made the following investments in this area, which we intend will have an impact on our emissions mitigation, resilience and capacity to adapt:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• rehabilitated compressors, air preheaters, steam leak elimination, burner replacement, and the implementation of other energy efficiency measures at our refineries and our petrochemicals operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• continued the strategy for the management and use of gas by our Exploration and Extraction segment, which included the closure of wells with high gas and oil ratios, reestablishment of boosters, overhaul of compressors, development of surface infrastructure for the management of production and operational flexibility for the development of new and existing fields;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• advanced compliance with the *Programas de Prevención y Control de Emisiones de Metano* (Methane Emission Prevention and Control Programs) in our facilities, focusing actions on the identification, detection and repair of methane leaks in equipment and accessories at exploration and production facilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• verified GHG emissions inventories at work centers participating in the Emissions Trading System Test Program and the National Emissions Registry Regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• exercised allowances rights corresponding to the fifth year of operations of the Pilot Phase and implemented controls to monitor processes that generate the highest generation of GHG emissions through work centers participating in the Emissions Trading System;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• concluded analysis of proposals applicable to our operations submitted to the Emissions Trading System Advisory Committee, of which Petróleos Mexicanos is a member;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• jointly conducted work to gather information to quantify methane emissions, identify mitigation actions and define investment requirements through the technical collaboration agreement between the United States Environmental Protection Agency (EPA) and Petroleos Mexicanos;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• carried out workshops with the Mexican Petroleum Institute and the World Bank to design methane reduction strategies aligned with global initiatives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• participated in an initiative promoted and led by the United Nations Environment Programme, pursuant to which we received and acted upon alerts generated by the Methane Alert and Response System of the International Methane Emissions Observatory, enabling us to identify significant methane emission events and implement targeted mitigation actions in furtherance of our international climate commitments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• commenced climate risk analyses for our Tula refinery and the Cangrejera Petrochemical Complex;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fully carried out climate risk analyses at the Gas Processing Complex ("GPC") in Ciudad Pemex, the GPC in Poza Rica and the Cadereyta Refinery; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• held five in-person risk analysis workshops based on the Technical Guide for Conducting On-Shore Climate Risk Analyses at the Tula and Cadereyta refineries, the Cangrejera Petrochemical Complex and the GPCs in Ciudad Pemex and Poza Rica.

Our sustainability plan, published in 2024, encompasses assessments of business risks associated with the energy transition and the impacts of climate change, commitments to reduce direct emissions in the near term from hydrocarbon processes under our control, and the ambition to reach net-zero emissions by 2050.

**Biodiversity**

We promote the conservation of priority ecosystems as part of our sustainability approach. In this context, the company manages the Voluntarily Designated Conservation Areas of Jaguaroundi and Tuzandépetl, where actions are implemented to protect biodiversity and environmental services. These areas contribute to the capture and storage of greenhouse gases, climate regulation, improvement of air and water quality, as well as the protection of local flora and fauna species.

During 2025, we continued operating the Jaguaroundi Ecological Park, located in Coatzacoalcos, Veracruz. This park is certified as an *Área Destinada Voluntariamente a la Conservación* (Voluntary Area for Conversation) by the *Comisión Nacional de Áreas Naturales Protegidas* (National Commission for Protected Natural Areas). It has an area of 960 hectares jungle, natural grassland, tropical oak forest and 57 hectares of bodies of water. Guided tours and workshops, among other environmental education activities, are held in this park for nearby communities, schools and industries. It functions as a refuge and feeding area for local species and acts as a buffer and safeguard zone for the Cangrejera, Morelos and Pajaritos petrochemical complexes. In 2025, this park stored a total of 109,772 tons of carbon across an active area of 960 hectares.

We also maintain the Tuzandépetl Ecological Park (TEP), located in the Municipality of Ixhuatlán del Sureste, Veracruz. With an area of 1,104 hectares, the TEP includes 600 hectares of wetlands, and surrounds infrastructure dedicated to the storage of hydrocarbons in caverns formed by salt domes. The TEP has been certified as a Voluntary Area for Conservation since 2011. The property includes extensions of aquatic vegetation such as popal, tular, hydroflotantes, as well as other types of vegetation such as mangroves, acahuales, palm groves, riparian forests and high jungles. There are various protected species of fauna, including the howler monkeys and spider monkeys and at least 105 other species of birds and bats. In addition to the environmental protection it provides, the TEP functions as an intermediate safeguard zone for the Tuzandépetl strategic storage center and protects surrounding populations from possible industrial risks. In 2025, this park stored a total of 52,616 tons of carbon across an active area of 1,104 hectares.

**HEALTH, SAFETY AND ENVIRONMENTAL PERFORMANCE**

We believe that we are in substantial compliance with current federal and state environmental laws and that we maintain an organizational structure designed to identify and mitigate environmental risks. In addition, our business segments have specialized departments that implement their own internal environmental programs, audits and facilities inspections. When these internal audits reveal problems or deficiencies, the business segments take the necessary measures to eliminate them.

In general terms, voluntary environmental auditing consists of three stages: (i) an audit and compliance diagnosis; (ii) the development of an action plan to correct irregularities; and (iii) the implementation of the action plan. If a company satisfactorily completes these three stages, ASEA or PROFEPA grants the audited company a clean industry certificate or an environmental quality certificate, indicating compliance with the applicable environmental legislation for its industry.

As of December 31, 2025, we have registered three of our facilities with NEAP with the objective of obtaining an "environmental quality" certificate for each facility. One of our facilities was re-certified during 2025. As of the date of this annual report, two more facilities are in the process of obtaining certification. Beginning in 2019, environmental authorities have prioritized the verification of industrial facility compliance with the Industrial Safety, Operational Safety and Environmental Protection Administration System (SASISOPA). In line with NEAP requirements, we are committed to maintaining environmental quality certificates in non-industrial facilities.

As part of our accident prevention strategy, we conduct root cause investigations into all incidents that occur during our operations. These investigations are carried out by multidisciplinary groups to identify the causes of these incidents and

establish and monitor corrective measures until they are fully implemented, both in the workplace where the accident occurred and in similar facilities. Despite these efforts, we continue to experience hazardous events at our facilities.

During 2025, we experienced the following nine hazardous events at our facilities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On February 8, 2025, a PEMEX worker died due to burns at sector Ductos Salamanca.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On May 9, 2025, a PEMEX worker died after receiving an electric shock at the Minatitlán Refinery.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On December 10, 2025, a contractor worker died while performing activities on the floating gate valve in Atasta.

In 2025, our lost time injury frequency rate decreased by 12.5%, going from 0.32 accidents per million man-hours worked with exposure to risk in 2024 to 0.28 in 2025. The Industrial Processes segment had the highest lost time injury rates during the year. Our lost days indicator due to injuries decreased by 37.5%, from 24 to 15 lost days per million man-hours worked with risk exposure from 2024 to 2025. Lost days are those in which work cannot be performed as a result of incapacitating injuries suffered at work or those for which compensation is paid for death. From 2024 to 2025, the lost time injury frequency rate of contractor personnel accidents decreased by 61.5%, from 0.13 to 0.05 accidents per million man-hours worked with exposure to risk.

In 2025, the main initiatives in industrial safety, occupational health and environmental protection were as follows:

Liabilities and Contingent Assets" for IFRS purposes. Estimated liabilities include assumptions resulting from an initial evaluation of damage, including land acreage to be remediated, depth and type of contamination. There is a possibility that the actual scope of remediation could vary depending upon information gathered during the initial evaluation and the remediation process. For a further discussion of our environmental liabilities, see Note 3-J and Note 19 to our consolidated financial statements included herein.

Unasserted or additional claims are not reflected in our identified liabilities. As of December 31, 2025, we were not aware of uncertainties with respect to joint and several liabilities that could affect our assessment of environmental contingencies or otherwise result in a major environmental liability. As a result, we believe we are positioned to know immediately of any claims and are therefore directly accountable for any claims that may be brought against us.

The Exploration and Extraction segment remains responsible for handling existing environmental liabilities—these responsibilities are not part of the Integrated E&P Contracts. Nevertheless, the Integrated E&P Contracts include environmental clauses related to the contractors' and the Exploration and Extraction segment's responsibility to ensure an adequate environmental performance and also establish the terms for compensation and repair of any new environmental impacts.

The initial evaluation and remediation of environmental liability sites are dependent upon the annual budget approved by the Mexican Congress.

On August 1, 2017, we were granted a favorable judgment by the Supreme Court of Justice of the Nation, which determined that we are not liable for material and environmental damages caused by hydrocarbons spills related to illegal tapping of pipelines, since the environmental damage was caused by third party criminal behavior.

**Environmental Projects and Expenditures**

In 2025, we spent Ps.11,514.1 million on environmental projects and related expenditures, as compared to Ps.7,504.3 million in 2024, an increase of 53.4%. For 2026, we have budgeted Ps.12,405.3 million mainly for the reduction of gas flaring in Exploration and Extraction activities, as well as for the integrated management of hazardous and non-hazardous waste, connate and residual water treatment, environmental risks management, soil sanitation and restoration, ecological protection services, environmental studies, air quality monitoring, greenhouse gas emissions reports, preventive maintenance of environmental protection equipment and acquisitions of equipment to address contingencies related to oil and gas spills.

We believe that the cost of complying with international environmental requirements related to the USMCA among the governments of Mexico, the United States and Canada, and Mexico's accession to the Organization for Economic Cooperation and Development, the Paris Agreement, the International Convention for the Prevention of Pollution from Ships, the Vienna Convention for the Protection of the Ozone Layer, the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal, the Stockholm Convention on Persistent Organic Pollutants, and the Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals and Pesticides in International Trade, among others, could cause a significant increase in our environmental expenditures.

**Social Responsibility** 

We understand social responsibility as the commitment we have to the communities where we carry out our hydrocarbon production, transformation and logistics activities. In compliance with applicable laws and regulations, we strive to build good community relationships based on trust, transparency and respect to the forms of coexistence of the communities. Through this and some other actions, we seek to give back to the communities, by generating shared benefits with stakeholders that favor our operational continuity and the generation of value.

During 2025, we implemented and continued various corporate social responsibility initiatives in communities where we carried out substantial activities in our value chain.

Our corporate and social responsibility goals are carried out through the following mechanisms:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• product donations of fuels and asphalt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the *Programa de Apoyo a la Comunidad y Medio Ambiente* (Program to Support Communities and the Environment, which we refer to as PACMA), which supports and implements social programs, actions and public works designed to improve the social conditions of the communities in which we operate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other instruments that provide a positive impact on communities such as Integrated E&P Contracts, through which we and our contractors commit to improving the quality of life in communities where we operate directly or indirectly; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mutually beneficial public works or projects, which we carry out in collaboration with local authorities and communities to improve infrastructure for the benefit of both Petróleos Mexicanos and the community.

In 2025, the total value of our social responsibility donations and contributions amounted to Ps.3,581.4 million. Our asphalt and fuel donations amounted to Ps.1,995.5 million. PACMA contributions amounted to Ps.1,465.3 million, and mutual benefit project contributions amounted to Ps.118.1 million. Additionally, a project related to the Integrated E&P Contracts was carried out for Ps.2.5 million.

Approximately 94.3% of our donations and contributions were assigned to the ten states with the highest activity in the oil and gas industry (Campeche, Chiapas, Guanajuato, Hidalgo, Nuevo León, Oaxaca, Puebla, Tabasco, Tamaulipas and Veracruz). The remaining 5.7 % were to the remaining states.

Notably, we took the following specific actions in 2025:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• contributed Ps.1,995.5 million in asphalt and fuel donations. Of our 2025 asphalt and fuel donations, 63.1 % was concentrated in the states of Campeche (Ps.452.8 million), Veracruz (Ps.309.0 million), Tamaulipas (Ps.187.1 million), Puebla (Ps.171.1 million) and Tabasco (Ps.138.2 million);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• undertook several social responsibility actions under our PACMA program. Approximately 45.4% of these actions were in Tabasco (Ps.665.8 million), approximately 16.2% were in Veracruz (Ps.237.7 million) and approximately 11.4% were in Hidalgo (Ps.166.4 million). The remaining Ps.395.3 million, or approximately 27.0% , were in Campeche, Chiapas, Ciudad de México, Guanajuato, Michoacán de Ocampo , Nuevo León, Oaxaca, Puebla, Tamaulipas and Zacatecas;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• contributed a total of Ps.118.1 million via mutual benefit projects, which were directed towards the state of Tabasco. These projects were for infrastructure improvements, such as the paving of roads; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• through the Integrated E&P Contracts instrument, construction of a community center in Altamira, Tamaulipas was carried out for an amount of Ps. 2.5 million.

In sum, we contributed Ps.1,585.9 million through programs, works and/or actions as follows: Ps. 897.8 million (56.6%) for infrastructure, Ps.434.1 million (27.4%) for health, Ps.111.6 million (7.0%) for education and sports, Ps.94.4 million (6.0%) for public safety and civil protection, Ps. 44.0 million (2.8%) for environmental protection, and Ps.4.0 million (0.3%) for productive projects.

**TRADE REGULATION, EXPORT AGREEMENTS AND PRODUCTION AGREEMENTS**

Although Mexico is not a member of OPEC, it has periodically announced increases and decreases in our crude oil exports reflecting production revisions made by other oil producing countries and entered into agreements with OPEC and non-OPEC members to reduce its oil exports, in order to contribute to crude oil prices stabilization.

On April 12, 2020, Mexico entered into an agreement with OPEC and non-OPEC countries to reduce world crude oil production. Pursuant to this agreement, the OPEC+ countries agreed to reduce their overall crude oil production by 9.7 million barrels per day from May 1, 2020 through June 30, 2020, by 7.7 million barrels per day from July 1, 2020 through December 31, 2020 and by 5.8 million barrels per day from January 1, 2021 through April 30, 2022. In particular, Mexico agreed to reduce its, and in turn our, crude oil production by 100,000 barrels per day for a period of two months beginning on May 1, 2020. While OPEC+ countries have since entered into further production agreements, including reductions in oil production announced in April and November of 2023, in April of 2025 and in March of 2026, no further agreements have been made between Mexico and OPEC and non-OPEC members as of December 31, 2025, and as of the date of this annual report.

On July 1, 2020, the USMCA entered into force, replacing NAFTA. The USMCA has not affected Mexico's rights, through PEMEX or other companies, to explore and exploit crude oil and natural gas in Mexico, to refine and process

crude oil and natural gas and to produce petrochemicals in Mexico. The USMCA continues the zero-tariff rate on the export of petrochemical products from Mexico to the United States that existed under NAFTA. However, any change in trade relations between Mexico, the United States and Canada as a result of the implementation and renegotiation of the USMCA could require us to renegotiate our contracts, limit our ability to explore and exploit crude oil or natural gas in Mexico, increase the tariff rate and/or lose business, resulting in an adverse impact on our business and the results of our operations. See "*Item 3—Key Information—Risk Factors—Risk Factors Related to Mexico—Economic and political developments in the United States may adversely affect Mexican economic policy and, in turn, our operations*."

**TAXES, DUTIES AND OTHER PAYMENTS TO THE MEXICAN GOVERNMENT** 

**General**

Taxes and duties applicable to us are a significant source of revenues to the Mexican Government. We contributed approximately 2.4% of the Mexican Government's revenues in 2024 and 2.7% in 2025. Until March 2025, we paid a number of special oil and gas taxes and duties, in addition to the other taxes and duties paid by some of the subsidiary companies, as described below under "*—Other Taxes*."

On December 19, 2024, the *Decreto de la Ley de Ingresos de la Federación para el ejercicio fiscal 2025* 

(2025 Federal Revenue Law) was published in the Official Gazette of the Federation and became effective on January 1, 2025. The 2025 Federal Revenue Law introduced changes to the fiscal regime applicable to Petróleos Mexicanos aimed at simplifying our fiscal framework and reducing the number of taxes and duties to which we are subject, consolidating the Derecho de Utilidad Compartida (Profit-Sharing Duty), the Derecho de Extracción de Hidrocarburos (Hydrocarbon Extraction Duty) and the Derecho de Exploración de Hidrocarburos (Hydrocarbon Exploration Duty) payable by Petróleos Mexicanos into a new Derecho Petrolero Para el Bienestar (Welfare Oil Duty), which is set at a general rate of 30% on oil and fuel production and 11.63% for non-associated gas. Subsequently, on March 18, 2025, the reform to the *Ley de Ingresos sobre Hidrocarburos* (Hydrocarbons Revenue Law) was published in the Official Gazette of the Federation, formally amending Article 39 and derogating Articles 41 through 45 of the Hydrocarbons Revenue Law to implement this consolidation on a permanent statutory basis. Additionally, as of January 1, 2025, Petróleos Mexicanos is no longer subject to income taxes. For more information, see "*—Special Note Regarding Mexican Energy Reform", "Item 4—Information on the Company—History and Development—Recent Energy Reform—New Fiscal Regime"*" and Note 21 to our consolidated financial statements included herein.

**Fiscal Regime for PEMEX**

For a description of the taxes and duties to which we are subject, see Note 21 to our consolidated financial statements included herein.

**Other Taxes**

Since 1994, our interest payments on our external debt have been subject to Mexican Government withholding taxes. Nevertheless, withholding taxes do not represent a substantial portion of our total tax liability.

We are subject to municipal and state taxes, such as real property and payroll taxes. However, because most of our facilities are located on federal property, which is not subject to municipal taxation, real property taxes are not a significant part of our overall taxes. Similarly, payroll taxes do not represent a substantial portion of our total tax liability.

In addition, we conduct certain operations outside of Mexico through *empresas subsidiarias* (subsidiary companies) organized under the laws of their respective jurisdictions, which may be subject to taxation in the jurisdiction of their incorporation or operations. The aggregate accrued income taxes related to the subsidiary companies were Ps.2,194.4 million in 2025, Ps.2,002.3 million in 2024 and Ps.3,212.9 million in 2023.

No assurance can be given that our tax regime will not change in the future. See "*Item 3—Key Information—Risk Factors—Risk Factors Related to our Relationship with the Mexican Government—We pay significant taxes and duties to the Mexican Government, which may limit our capacity to expand our investment program or negatively impact our financial condition*."

**Item 4A.&nbsp;&nbsp;&nbsp;&nbsp;Unresolved Staff Comments** 

Not applicable.

**Item 5.&nbsp;&nbsp;&nbsp;&nbsp;Operating and Financial Review and Prospects**

**General** 

We earn income from**:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• export sales, which consist of sales of crude oil and condensates, petroleum products and petrochemical products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• domestic sales, which consist of sales of natural gas, petroleum products (such as gasoline, diesel fuel and LPG) and petrochemical products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the incentive for automotive fuels, through which we can recover from the Mexican Government the difference between the international reference price of gasoline and the price at which the gasoline is traded in the domestic market; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other sources, including financial and investment income and insurance revenue.

Our operating expenses include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cost of sales, including the cost of purchases of imported petroleum and other products, the acquisition and production costs of inventories (depreciation, amortization, salaries, wages and benefits, including a portion of the cost of the reserve for employee benefits and expenses related to the production process), maintenance, and exploration and unsuccessful drilling expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• transportation and distribution expenses (including a portion of the net cost of employee benefits for the period); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• administrative expenses (including a portion of the net cost of employee benefits for the period.

Our income is affected by a number of factors, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in international prices of crude oil, petroleum products and petrochemical products, which are denominated in U.S. dollars, and domestic prices of petroleum products, which are denominated in pesos;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the type and volume of crude oil produced and exported;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the type and volume of natural gas produced, processed and sold domestically and internationally;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the results of development and exploration activities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the amount of taxes, duties and other payments that we are required to make to the Mexican Government;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fluctuations in the peso-U.S. dollar exchange rate; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Mexican and global economic conditions, including the levels of international interest rates.

**Overview** 

In 2025, we remained focused on strengthening our financial position despite ongoing operational challenges. We received Ps.395.3 billion in equity contributions from the Mexican Government, an increase of 152.6% over the Ps.156.5 billion we received in 2024. Additionally, our outstanding debt decreased by 22.6%, from Ps.1,978.8 billion as of December 31, 2024, to Ps.1,531.3 billion (U.S.$85.2 billion) as of December 31, 2025. Of this total, Ps. 588.7 billion (U.S.$32.8 billion), or 38.4% of our existing indebtedness, is scheduled to mature in the next three years, including Ps.345.2 billion (U.S.$19.2 billion) coming due in 2026.

Prices of crude oil, natural gas and petroleum products remained volatile in 2025, similar to 2024, due to ongoing market conditions. The average price of Mexican crude oil exports decreased from U.S.$70.20 per barrel in 2024 to U.S.$61.75 per barrel in 2025. Our total crude oil and condensates production decreased 7.0% in 2025, our production of 1,618.5 thousand barrels per day remained below our target of 1,891 thousand barrels per day.

*Going Concern* 

Our consolidated financial statements as of December 31, 2025 and 2024 have been prepared on a going concern basis, which assumes that we can meet our payment obligations and our operating continuity. We discuss below, and in Notes 2-C and 22-F to our consolidated financial statements, the circumstances that have caused these negative trends and the concrete actions we are taking to improve our results, strengthen our ability to continue operating and achieve revenue maximization and efficiencies. We continue operating as a going concern, and our consolidated financial statements do not contain any adjustments that might result from the outcome of this uncertainty.

We have substantial debt, which we have incurred primarily to fund our operating expenses and finance capital investment projects. The cash flow derived from our operations in recent years has not been sufficient to fund our operations and capital expenditure programs. Our operational continuity and timely compliance with our financial obligations depend on the recurrence of equity contributions from the Mexican Government. During 2025, we received equity contributions of Ps. 395.3 billion from the Mexican Government, exceeding the initial expected contributions of Ps. 136.1 billion due to additional support for our liability management strategy. In the absence of continued Mexican Government support, we would be unable to meet our financial obligations as they become due.

During 2025, 2024 and 2023 we recognized a net loss of Ps.81.7 billion, a net loss of Ps.780.6 billion and net income of Ps.8.2 billion, respectively. In addition, as of December 31, 2025 and 2024, we had negative equity of Ps.1,905.8 billion and Ps.1,983.8 billion, respectively, mainly due to continuous net losses. In addition, we had a negative working capital of Ps.530.5 billion and Ps.768.0 billion, as of December 31, 2025 and 2024, respectively. See "*Item 3—Risk Factors—Risk Factors Related to Our Operations—We have a substantial amount of indebtedness and other liabilities and are exposed to significant liquidity constraints, which could make it difficult for us to obtain financing on favorable terms and could adversely affect our financial condition, results of operations and ability to repay our debt and, ultimately, our ability to operate as a going concern without additional support from the Mexican Government, which we may not receive*" for more information.

Beginning in the second half of 2025, PEMEX implemented a liability management strategy which resulted in a 22.6% decrease in our total indebtedness, from Ps.1,978.8 billion as of December 31, 2024, to Ps.1,531.3 billion as of December 31, 2025, primarily attributable to equity contributions from the Mexican Government, other liability management transactions, and prepayments of outstanding indebtedness. Notwithstanding these measures, PEMEX maintains a significant level of financial debt.

Our future cash flows, including the ability to refinance debt, are uncertain due to the circumstances outside our control. A sustained decrease in crude oil prices below the budget average price for 2026, an economic slowdown or an increase in the cost of financing would have an adverse impact on our results of operation and cash flows and may require us to consider additional actions to address these shortfalls.

In 2025, certain rating agencies upgraded our credit rating, mainly driven by stronger expected government support and a closer sovereign linkage, as well as expected improvements to our liquidity and maturity schedule, supported by government financial measures and our 2025–2035 Strategic Plan (as defined below), see "*—2025-2035 Strategic Plan*." However, we remain subject to credit rating downgrades in the future. See "*Item 3—Risk Factors—Risk Factors Related to Our Operations—Downgrades in our credit ratings could negatively impact our access to the financial markets and cost of financing*" for more information.

We have budget autonomy and, in public finance terms, are subject to the cash flows financial balance goals approved in the *Decreto de Presupuesto de Egresos de la Federación* ("Federal Expenditure Budget Decree"). This represents the difference between our gross revenues (inflows) and our total budgeted expenditures (outflows) including the financial cost of our debt, which is proposed by the Ministry of Finance and Public Credit and approved by the Chamber of Deputies. The Federal Budget for 2026 authorized us to have a financial balance budget of Ps.263.5 billion and conduct financing activities that do not represent a net debt in terms of public debt greater than Ps.261.6 billion and other financing activities that do not represent net public debt. This financial balance does not consider the payment of principal during 2026, which we expect to cover with equity contributions from the Mexican Government. We have short-term debt principal maturities (including interest payable) of Ps.345.2 billion as of December 31, 2025.

The combined effect of the above-mentioned events indicates the existence of significant doubt about our ability to continue as a going concern. For more information on the circumstances that have caused these negative trends and the

concrete actions we are taking to improve our results, strengthen our ability to continue operating and achieve revenue maximization and efficiencies, see Notes 22-F and 28 to our consolidated financial statements included herein.

*2025-2035 Strategic Plan*

On August 5, 2025, as part of the corporate reorganization pursuant to the Energy Reform Decree, we announced our Strategic Plan 2025–2035 (the "Strategic Plan"). The Strategic Plan sets forth our principal long-term roadmap and is, organized around two core pillars: a productive pillar focused on strengthening hydrocarbons, petrochemicals and fertilizers while reducing emissions and deepening social responsibility, and a financial pillar focused on budget sustainability, relieving the liability burden and freeing resources for productive uses. The Strategic Plan sets forth seven operational courses of action and a capitalization and financing strategy. The following summarizes each principal line of action:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Strengthen exploration and extraction: We seek to (i) meet national hydrocarbon production targets by optimizing producing fields, accelerating development of recently discovered fields and bringing exploratory discoveries into production, (ii) maintain a reserve-to-production ratio of at least 10 years by continuing targeted exploration efforts in existing production areas, pursuing access to new areas with additional prospective resources, and evaluating complex-geology and frontier areas through contractual schemes, including development structures with third-parties that may involve private-sector participation (*Proyectos de Desarrollo Mixto*) and (iii) prioritize high-impact operational investment, including well conservation, field development, facility maintenance, drilling and well interventions, secondary recovery and the execution of service contracts, exploration and extraction contracts and mixed-development contracts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Improve industrial processes: We seek to (i) improve the profitability and performance of our industrial operations by reducing costs and imports, improving petroleum-product distribution and increasing in-house maintenance, (ii) increase gasoline, diesel and jet fuel production and reduce fuel-oil production through improved refinery yields, optimization of the Olmeca and Deer Park refineries and start-up of the coker projects at Tula and Salina Cruz and (iii) recover gas-processing capacity in line with wet-gas and condensate production, increase liquids recovery, rehabilitate petrochemical infrastructure and strengthen fertilizer production, including the modernization of the Escolín petrochemical complex through private-investment schemes to increase urea output.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Advance energy transition and new energy businesses: We seek to (i) consolidate natural gas as a distinct business line, leveraging our cogeneration infrastructure to improve energy efficiency, reduce operating costs and lower emissions, (ii) increase gas-processing capacity in support of upstream production and domestic demand, (iii) pursue electricity-generation and cogeneration projects with CFE and private co-investors and (iv) further evaluate renewable energy, circular-economy (i.e., models designed to minimize waste and maximize resource reuse), biofuel and other low-carbon opportunities that could support our long-term transition into a broader energy company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Strengthen logistics and safeguard strategic infrastructure: We seek to (i) consolidate a safe logistics platform supporting uninterrupted exploration and extraction operations and the efficient supply, transportation and storage of petroleum products, gas and petrochemicals, (ii) preserve and restore storage and treatment capacity, rehabilitate pipeline, terminal, marine and related infrastructure, and improve the availability, flexibility and integrity of transportation and storage assets and (iii) strengthen protection of infrastructure and energy products through enhanced quality verification, continuous pipeline monitoring, upgraded measurement and volumetric-control systems, digital control tools and closer coordination with public-security authorities to combat the illicit fuels market.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Strengthen commercialization and market positioning: We seek to (i) maximize revenues through the sale of our products under open, competitive and transparent schemes designed to establish fair market prices while improving access to fuels, (ii) consolidate our position as the principal marketer of transportation fuels, leverage increased production of higher-value petroleum products to reduce gasoline imports and position Petróleos Mexicanos as a net diesel exporter and (iii) expand commercialization of other petroleum and petrochemical products through more efficient processes and broader market diversification.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Promote efficient administration and services, fiscal discipline and institutional strengthening: We seek to (i) improve our cost structure and increase operating efficiency by eliminating duplications, improving infrastructure use and maintaining austerity and budget discipline without impairing operational continuity or the safety of workers and facilities, (ii) reduce unnecessary administrative spending and generate sustainable savings through a

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

fiscal discipline and financial stewardship program, and (iii) strengthen our institutional structure, transparency, accountability and centralized oversight across all business lines.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Build a more sustainable energy company: We seek to (i) integrate sustainability across our value chain by improving energy efficiency, reducing emissions, strengthening operational reliability and industrial safety, and promoting social responsibility, (ii) reaffirm our commitment to zero routine gas flaring by 2030 in exploration and extraction and establish 2030 emissions-intensity reduction targets for exploration and extraction, gas processing and refining, (iii) pursue initiatives capable of reducing approximately 25 million tons of CO2e by 2030 and state an ambition to reach net-zero emissions by 2050, and (iv) address water use and reuse, environmental remediation, sulfur-oxide reduction, methane management, and (v) strengthen anti-corruption and compliance initiatives.

In parallel with the operational courses of action described above, our Strategic Plan includes a capitalization and financing strategy intended to strengthen liquidity, preserve supply-chain stability and reduce dependence on short-term financing. This strategy combines Mexican Government support, capital contributions, debt refinancing, liability management measures, attention to supplier and contractor payables, tighter financial discipline, more rigorous investment screening, risk management, selective divestment of non-strategic assets, and sustainable-financing and ESG-linked programs. This strategy is articulated around five financial courses of action, as summarized below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Managing our financial and commercial liabilities: We seek to manage our liabilities by (i) reducing our short-term bank debt by optimizing the use of Mexican Government contributions, (ii) softening the maturity schedule of our international bonds by refinancing to reduce maturity pressure and (iii) addressing our commercial debt due to suppliers and contractors based on available resources, set schedules and in line with principles of transparency and equity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Optimizing our financial operations: We seek to structurally improve our balance sheet and strengthen cash flow generation by increasing operational efficiency and promoting responsible use of resources, through (i) implementing controls linked to results and cash flows to avoid structural deficits, (ii) reinforcing investment project evaluation through more rigorous economic and financial criteria and periodic performance monitoring, (iii) strengthening our enterprise risk management framework, including crude price hedging and environmental and safety compliance metrics and (iv) divesting from non-strategic or non-profitable assets and (v) restructuring our subsidiary companies to redirect capital toward higher-value projects.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Financing our investment program: We seek to prioritize public productive investment toward projects with the highest value generation and lowest risk, with the aim of maintaining a reserves-to-production ratio of at least 10 years, improving infrastructure performance and yields and increasing installed capacity and reliability of storage and distribution services.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Sound financial governance: We seek to reinforce the governance of our financial process to ensure responsible, prudent, ethical, and transparent decision-making fully aligned with our strategic objectives and strict compliance with financial limits by promoting a compliance culture that addresses risks such as corruption, fraud and conflicts of interest.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Sustainable financing framework and ESG programs: We intend to (i) explore opportunities to align our financing activities with sustainable projects and progressively integrate sustainability considerations into our investment approval and prioritization processes, (ii) work toward developing timely and reliable information systems to track progress against established targets and identify areas for improvement, and (iii) foster clear and transparent communication with stakeholders through enhanced reporting practices over time.

*Mexican Government Support* 

The application of the tax credit decree to automotive fuels published in the Official Gazette of the Federation on March 4, 2022, remained in effect during 2024 and 2025. This decree allows us to substantially recover from the Mexican Government the difference between the international reference price of gasoline and diesel and the price at which they trade in the domestic market, accounting for inflation. See "*Item 5—Results of Operations—Results of Operations of Petróleos Mexicanos and the Subsidiary Companies—For the Year Ended December 31, 2025, Compared to the Year Ended December 31, 2024—Total Revenues.*"

As of January 1, 2025, the Mexican Government has consolidated several duties payable by Petróleos Mexicanos into the new Welfare Oil Duty, which is set at a general rate of 30% on oil and fuel production and 11.63% for non-associated

gas. See "*Item 4—Taxes, Duties and Other Payments to the Mexican Government*" and "*Item 4—Recent Energy Reform—New Fiscal Regime*."

During 2025, we received equity contributions from the Mexican Government totaling Ps.395.3 billion to continue strengthening our financial position.

The Mexican Government's Federal Budget for 2026 includes Ps.263.5 billion (U.S.$14.7 billion) in capital contributions for us during 2026. As of the date of this annual report, we have received Ps.58.3 billion in capital contributions from the Mexican Government.

In addition, we plan to raise funds from the markets in accordance with prevailing conditions and to refinance our debt. See Notes 22-F and 28 to our consolidated financial statements included herein.

*Budget* 

In public finance terms, we are subject to the cash flows financial balance goals approved in the Federal Expenditure Budget Decree. This represents the difference between our gross revenues (inflows) and our total budgeted expenditures (outflows) including the financial cost of our debt, which is proposed by the Ministry of Finance and Public Credit and approved by the Mexican Congress.

In the Federal Budget of 2026, we were authorized to maintain a financial balance budget of Ps. 263.5 billion. This budget will finance activities that do not result in a net debt exceeding Ps. 261.6 billion in terms of public debt or other financing activities that do not result in a net debt. This financial balance does not consider the payment of principal during 2025, which PEMEX expects to cover with equity contributions from the Mexican Government. As of December 31, 2025, we have short-term debt principal maturities of Ps.345.2 billion, including interest payable.

Taking into account the conditions mentioned above and the price of crude oil level observed at the date of this annual report, we plan to increase our budget revenues, improve our budget deficit and potentially increase our investment spending during the year.

*Results of Operations and Financial Condition in 2025* 

For the year ended December 31, 2025, our results of operations improved, from a net loss of Ps.780.6 billion in 2024 to a net loss of Ps.81.7 billion in 2025. This improvement was primarily due to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 175.0 billion decrease in cost of sales; mainly due to a decrease in import purchases and a decrease in hydrocarbon extraction and exploration duties and taxes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 45.4 billion decrease in impairment of fixed assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 11.8 billion increase in other revenues;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 8.9 billion decrease in financing costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 49.2 billion decrease in the cost of derivative financial instruments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 499.7 billion increase in foreign exchange income; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 289.6 billion decrease in duties, taxes and other.

These effects were partially offset by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 144.3 billion decrease in total revenues, mainly due to a decrease in the volume of Mexican crude oil for export sales;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps.15.8 billion increase in administrative expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 3.8 billion decrease in financing income;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 194.6 billion increase in Welfare Oil Duty; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 16.8 billion increase in other expenses.

For more information on our results of operations, see "*—Results of Operations of Petróleos Mexicanos and the Subsidiary Companies—For the Year Ended December 31, 2025, Compared to the Year Ended December 31, 2024*" below.

In 2025, our total equity (deficit) improved by Ps.78.0 billion from negative Ps.1,983.8 billion as of December 31, 2024, to negative Ps.1,905.8 billion as of December 31, 2025. For more information on the improvement in our total equity (deficit) see "*—Liquidity and Capital Resources—Equity Structure and Mexican Government Contributions*" below. This result was mainly due to equity contributions of Ps.395.3 billion from the Mexican Government. This impact was partially offset by our net loss of Ps.81.7 billion for the year, actuarial losses on employee benefits of Ps. 173.6 billion, and a negative currency translation effect of Ps.62.0 billion.

Our accounts receivable from customers, including financing and non-financing receivables, decreased by 14.3% in 2025, from Ps.233.6 billion as of December 31, 2024, to Ps.200.2 billion as of December 31, 2025, mainly due to a decrease in taxes to be recovered and prepaid taxes.

As of December 31, 2025, we owed our suppliers Ps.436.7 billion, a 13.7% decrease as compared to the Ps.506.0 billion owed as of December 31, 2024. As of March 31, 2026, we have paid approximately 38.6% of the total outstanding balance due to suppliers and contractors as of December 31, 2025.

*Operating Information* 

In 2025, our crude oil and condensates production averaged 1,618.5 thousand barrels per day, representing a decrease of 122.6 thousand barrels per day, or 7.0% compared to 1,741.1 thousand barrels per day in 2024. The decrease was primarily driven by the decline in production at some of our main fields, including Zaap, Quesqui, Xanab and Pokche, as a result of unusually bad weather conditions affecting the continuity of offshore operations and delays in the completion of wells with high complexity due to their depth, pressure and temperature conditions.

Our average natural gas production increased by 1.0% in 2025, from 4,511.6 million cubic feet per day in 2024 to 4,556.1 million cubic feet per day in 2025. Natural gas production associated with crude oil production accounted for 56.9% of total natural gas production in 2025, with the remainder of natural gas production consisting of extraction from fields holding natural gas reserves. As of December 31, 2025, 127 of our 357 gas producing fields, or 35.6%, produced non-associated gas. These non-associated gas fields accounted for 43.1% of all of our natural gas production in 2025.

In 2025, 60 development wells were completed — 46 fewer than the 106 completed in 2024—with an associated daily production of 113.6 barrels of liquid and 595.4 million cubic feet of gas, and annual daily average of 59.4 thousand barrels of liquids and 252.3 million cubic feet of gas. Of these wells, 44 were onshore and 16 offshore. In terms of classification, 44 wells were oil and gas producers, 11 gas and condensate producers, 1 non-productive well, 1 non-commercial producer and 3 abandoned wells. Drilling activity showed a year-over-year decline in completed wells, with activity centered on development. The success rate for development wells, meaning the percentage of finished wells that are productive, was 91.7%. For more information about our production levels, see "Item 4—Information on the Company—Business Overview—Exploration and Extraction—Crude Oil and Natural Gas Production."

In 2025, crude oil processing in the National Refining System ("NRS") averaged 1,013.8 thousand barrels per day, representing an increase of 108.2 thousand barrels per day, or 11.9%, compared to 905.6 thousand barrels per day in 2024. The refineries with the highest processing levels in 2025 were Tula, which averaged 212 thousand barrels per day, Salina Cruz, which averaged 201 thousand barrels per day, Cadereyta, which averaged 146 thousand barrels per day, Dos Bocas (Olmeca), which averaged 134 thousand barrels per day, and Salamanca which averaged 117 thousand barrels per day.

The NRS's installed atmospheric distillation capacity in 2025 was 1,730 thousand barrels per day, as compared to 1,640 thousand barrels per day in 2024.

Petroleum products production averaged 1,022 thousand barrels per day in 2025, representing an increase of 11.9% compared to the 914 thousand barrels per day averaged in 2024.

Production of high-value distillates increased by 24.5% to 626.5 thousand barrels per day in 2025, from 503.1 thousand barrels per day in 2024. This increase was primarily supported by the performance of the Olmeca refinery, which began continuous operations in February 2025 and progressively ramped up processing capacity throughout the year, as well as the start-up of the coker unit at the Tula refinery in July 2025.

As a result, considering total gasoline production, the distillate yield increased 6.3 percentage points, to 65.2% in 2025 from 58.9% in 2024.

The variable refining margin of the NRS in 2025 was U.S.$6.13 per barrel, or U.S.$1.92 higher than the U.S.$4.21 in 2024. This increase was primarily due to higher distillate production from NRS and lower crude oil prices.

*Armed conflict and related destabilization of world energy markets* 

The prices of oil and natural gas remain extremely volatile as a result of ongoing armed conflicts, including the military conflict involving Russia and Ukraine, the conflicts in Gaza and Lebanon and the war involving Iran, Israel, the United States of America and several other countries in the Middle East— as well as disruptions in strategic maritime transport routes, including the Red Sea and the Strait of Hormuz, which are critical corridors for global energy trade. Our revenues and profitability are heavily dependent on the prices we receive from sales of oil and natural gas. Oil prices are particularly sensitive to actual and perceived threats to global political stability and to changes in production from OPEC and OPEC+ member states and other oil-producing nations. Destabilization of global oil and gas prices could reduce our sales and adversely affect our results and profitability.

During 2025, the price of the Mexican crude oil export mix decreased by U.S.$13.08 or 19.6%, from U.S.$66.70 per barrel in 2024 to U.S.$53.62 per barrel in 2025, which was reflected in the decrease in the value of our revenues.

Total sales decreased by 8.6% or Ps.144.2 billion in 2025, from Ps.1,672.7 billion in 2024 to Ps.1,528.5 billion in 2025, mainly due to a decrease in the volume and in the average price of Mexican crude oil for export sales.

**Sales Volumes and Prices** 

The profitability of our operations in any particular accounting period is directly related to the sales volume of, and average realized prices for, the crude oil and natural gas that we sell. These average realized prices for crude oil and natural gas fluctuate from one period to another due to world market conditions and other factors.

*Export Volumes and Prices* 

In 2025, Petróleos Mexicanos sold crude oil to PMI, which then sold it to international clients. The volume of crude oil that we export is the volume delivered to international clients. PMI bases crude oil export price formulas on a basket of international reference prices and a constant set according to specific market conditions. We determine export prices of refined products, petrochemicals and natural gas by reference to market conditions and direct negotiations with our clients.

Significant changes in international crude oil prices directly affect our financial results. The impact of changes in crude oil prices on our refining activities and petrochemicals business depends on:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the magnitude of the change in crude oil prices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• how quickly petroleum and petrochemical product prices in international markets adjust to reflect changes in crude oil prices; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the extent to which prices in Mexico, where we sell most of our petroleum products and petrochemicals, reflect international prices for those products.

The following table sets forth the weighted average market price per barrel of crude oil that PMI received from exports and the average price of the United States benchmark (as the main market for Mexican crude oil), West Texas Intermediate (WTI) crude oil, for the years indicated. The average price differential between WTI and the crude oil that we exported in the last three years fluctuated between U.S.$6.70 in 2023 to U.S.$3.76 in 2025, which is mainly the result of fluctuations in

the price of other benchmarks on which our pricing formulas for crude oil are based. See "*Item 4—Information on the Company—Business Overview—International Trading*."

&nbsp;&nbsp;&nbsp;&nbsp;Numbers may not total due to rounding.

*Source: PEMEX's audited consolidated financial statements, prepared in accordance with IFRS.*

**Relation to the Mexican Government** 

As of December 31, 2025, Petróleos Mexicanos is a public entity of the Mexican Government, rather than a corporation organized under Mexican law. On March 19, 2025, the subsidiary entities were dissolved and all of their assets, liabilities, rights and obligations were assumed by, and transferred to, us. For more information, see "*Item 4—Information on the Company—History and Development—Recent Energy Reform.*" We do not have the power to issue shares of equity securities evidencing ownership interests and are not required, unlike Mexican corporations, to have multiple shareholders. Our financing obligations do not constitute obligations of, and are not guaranteed by, the Mexican Government. Effective March 19, 2025, the President of Mexico appoints three of the eight members of our Board of Directors as representatives of the Mexican Government, including the Secretary of Energy, who serves as the Chairperson of our Board of Directors, and the Secretary of Finance and Public Credit. The President of Mexico also nominates three independent members to our Board of Directors, whose appointment must be ratified by the Mexican Senate.

Pursuant to the 2025 Petróleos Mexicanos Law, our consolidated annual budget, including our financing program, must be submitted to the Ministry of Finance and Public Credit, which has the authority to adjust our financial balance goal and the ceiling on our wages and salary expenditures for the fiscal year. The Mexican Government incorporates our consolidated annual budget and financing program into its budget, which the Chamber of Deputies must approve each year. The Mexican Congress has the authority to adjust our annual financial balance goal at any time by amending applicable law. In addition, any proposal by our Board of Directors to change our annual financial balance goal, increase the limit on our wages and salary expenditures or adjust our financing program must be approved by the Chamber of Deputies.

**Consolidation** 

Our financial statements consolidate the results of Petróleos Mexicanos and the subsidiary companies as of December 31, 2025. Certain non-material subsidiary companies are not consolidated and are accounted for under either the cost method or the equity method. For more information on the basis for consolidation and a list of the consolidated subsidiary companies, see Note 3-A and Note 5 to our consolidated financial statements included herein.

**Export Agreements and Production Agreements** 

Though Mexico is not a member of OPEC, it has periodically announced increases and decreases in our crude oil exports reflecting production revisions made by other oil producing countries and entered into agreements with OPEC and non-OPEC members to reduce its oil exports, in order to contribute to crude oil prices stabilization.

On April 12, 2020, Mexico entered into an agreement with OPEC and non-OPEC countries to reduce world crude oil production. Pursuant to this agreement, the OPEC+ countries agreed to reduce their overall crude oil production by 9.7 million barrels per day from May 1, 2020 through June 30, 2020, by 7.7 million barrels per day from July 1, 2020 through December 31, 2020 and by 5.8 million barrels per day from January 1, 2021 through April 30, 2022. In particular, Mexico

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

agreed to reduce its, and in turn our, crude oil production by 100,000 barrels per day for a period of two months beginning on May 1, 2020. While OPEC+ countries have since entered into further production agreements, including reductions in oil production announced in April and November of 2023, in April of 2025 and in March of 2026, no further agreements have been made between Mexico and OPEC and non-OPEC members as of December 31, 2025, and as of the date of this annual report.

**Results of Operations** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A.Results of Operations of Petróleos Mexicanos and the Subsidiary Companies—For the Year Ended December 31, 2025, compared to the Year Ended December 31, 2024**

*Total Revenues* 

Total revenues decreased by 8.6% or Ps. 144.2 billion in 2025, from Ps. 1,672.7 billion in 2024 to Ps. 1,528.5 billion in 2025. The decrease in total revenues was mainly due to a decrease in the volume of Mexican crude oil for export sales

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

(Ps.133.8 billion), a decrease in the weighted average price of Mexican crude oil for export sales (Ps.39.6 billion) and a decrease in the domestic sales volume of diesel, jet fuel, natural gas liquids and liquefied gas (Ps.29.5 billion). This decrease was partially offset by an increase in the domestic sales prices of gasoline, diesel, jet fuel, natural gas liquids and liquefied gas (Ps. 39.8 billion), as well as an increase in foreign currency variations (Ps. 19.3 billion).

From January 1 to December 31, 2025, the average Mexican export crude oil price was U.S. $61.75 per barrel, as compared to U.S. $70.20 per barrel for the same period in 2024.

*Domestic Sales* 

Domestic sales increased by 1.1% or Ps. 10.3 billion in 2025, from Ps. 977.7 billion in 2024 to Ps.988.0 billion in 2025, mainly due to increases in the sales prices of gasoline, diesel, jet fuel, natural gas liquids and liquefied gas. Domestic sales of petroleum products remained substantially flat in 2025, at Ps. 887.8 billion as compared to Ps. 887.5 billion in 2024, mainly due to a 1.9% increase in the sales prices of gasoline, a 3.0% increase in the sales prices of diesel, a 10.0% increase in the sales prices of jet fuel, a 60.4% increase in the sales prices of natural gas liquids and 19.0% increase in the sales prices of liquefied gas. This increase was partially offset by a decrease of 5.4% in the domestic sales volume of diesel, a decrease of 5.0% in the domestic sales volume of jet fuel, a decrease of 13.1% in the domestic sales volume of natural gas liquids and a decrease of 16.0% in the domestic sales volume of liquefied gas.

Domestic sales of LPG remained substantially flat in 2025 at Ps.48.4 million, the same as in 2024.

Domestic sales of natural gas increased by 39.4% in 2025, from Ps. 19.3 billion in 2024 to Ps. 26.9 billion in 2025, primarily due to a 60.4% increase in its sales price, partially offset by a 13.1% decrease in sales volume.

*Export Sales* 

Export sales decreased by 22.3% in peso terms in 2025 (with U.S. dollar-denominated export revenues translated to pesos at the exchange rate on the date of the corresponding export sale) from Ps. 691.9 billion in 2024 to Ps. 537.8 billion in 2025. This decrease was mainly due to a 28.2% decrease in the sales volume of Mexican crude oil export in 2025, compared to 2024. From January 1 to December 31, 2025, the average Mexican export crude oil price was U.S. $61.75 per barrel, as compared to U.S. $70.20 per barrel for the same period in 2024.

Excluding the trading activities of the Trading Companies and Deer Park, export sales to third parties decreased by 29.0% in peso terms, from Ps. 488.8 billion in 2024 to Ps. 346.9 billion in 2025. In U.S. dollar terms, excluding the trading activities of the Trading Companies and Deer Park, total export sales (which are U.S. dollar denominated) decreased by 32.6% in 2025, from U.S. $26.1 billion in 2024 to U.S. $17.6 billion in 2025. This was primarily due to 28.2% decrease in the sales volume of Mexican export crude oil in 2025, compared to 2024. The trading and export activities of the Trading Companies and Deer Park generated additional revenues of Ps. 190.9 billion in 2025, 6.0% lower in peso terms than the Ps. 203.1 billion generated in 2024. This decrease was mainly due to lower export sales of Deer Park by decreases in the sales volume of gasoline and distillates.

Crude oil and condensate export sales accounted for 46.7% of total export sales in 2025, as compared to 54.6% in 2024. These crude oil and condensate sales decreased in peso terms by 33.5% in 2025, from Ps. 378.1 billion in 2024 to Ps. 251.3 billion in 2025 and in U.S. dollar terms by 36.7%, from U.S. $20.7 billion in 2024 to U.S. $13.1 billion in 2025. The average Mexican crude oil export price in 2025 was 12.0% lower than the average price of U.S. $70.20 per barrel in 2024.

Export sales of petroleum products, including natural gas and natural gas liquids increased from 12.9% of total export sales in 2024 to 14.1% of those export sales in 2025. Export sales of petroleum products, including products derived from natural gas and natural gas liquids, decreased by 14.8%, from Ps. 88.9 billion in 2024 to Ps. 75.7 billion in 2025, primarily due to a decrease in the sales volume of fuel oil.

Export sales of petrochemical products (including certain byproducts of the petrochemical process) decreased by Ps. 0.4 billion in 2025, from Ps. 3.9 billion in 2024 to Ps. 3.5 billion in 2025, primarily due to a decrease in sales volume by Grupo Fertinal, S.A. de C.V.

*Services Income* 

Services income decreased by 15.6% in 2025, from Ps. 3.2 billion in 2024 to Ps. 2.7 billion in 2025, primarily as a result of a decrease in transportation services provided to third parties.

*Cost of Sales*

Cost of sales decreased by 12.2%, from Ps. 1,435.5 billion in 2024 to Ps. 1,260.5 billion in 2025. This decrease was mainly due to: (1) a decrease of Ps. 96.9 billion in import purchases, primarily due to a decrease in volume of magna gasoline and diesel, and a decrease in the purchase price of imported products, (2) a Ps. 47.5 billion decrease in the hydrocarbons extraction and exploration duties and taxes, (3) a Ps. 32.5 billion decrease in variation of the valuation of inventory, due to the variations in standard and real costs and the difference between the balances as of the beginning of the year and the end of the period; and (4) a Ps. 12.5 billion decrease in the costs associated with unsuccessful wells. This decrease was partially offset by (1) an increase of Ps. 17.7 billion in the IEPS tax.

*Impairment of Wells, Pipelines, Properties, Plant and Equipment, net*

Impairment of wells, pipelines, properties, plant and equipment decreased by Ps. 45.4 billion in 2025, from a net impairment of Ps. 53.5 billion in 2024 to a net impairment of Ps. 8.1 billion in 2025. This net impairment was primarily due to Ps. 23.2 billion net impairment related to our logistics infrastructure assets, due to lower estimated future cash flows, and a Ps.1.1 billion net impairment in Industrial Processes cash generating units mainly due to lower variable margin of refining process. This impairment was partially offset by net reversals of impairment in: Exploration and Extraction cash generating units amounted Ps.12.6 billion, mainly due to a decrease in the discount rate; and a Ps.3.5 billion in Energy Transformation cash generating unit, due to the increase in gross margin due to higher sale prices.

*Administrative Expenses and Distribution, Transportation and Sale Expenses* 

Administrative expenses and distribution, transportation and sale expenses increased by Ps. 23.5 billion in 2025, from Ps. 187.3 billion in 2024 to Ps. 210.8 billion in 2025, mainly due to increases in net periodic cost of employee benefits.

*Impairment losses on trade receivables*

Impairment losses on trade receivables decreased by Ps. 2.5 billion in 2025, from Ps. 15.4 billion in 2024 to Ps. 12.9 billion in 2025, mainly due to a decrease in uncollectible export accounts due to the lack of a reasonable expectation of recovery.

*Other Revenues* 

Other revenues increased by Ps. 11.8 billion in 2025, from Ps. 18.5 billion in 2024 to Ps. 30.3 billion in 2025. This increase was mainly attributable to Ps. 9.3 billion in income from the recovery of insurance claims related to the fire on the Nohoch-A platform in 2023.

*Other Expenses* 

Other expenses increased by Ps. 16.8 billion in 2025, from Ps. 15.5 billion in 2024 to Ps. 32.3 billion in 2025. This increase was mainly due to a Ps. 15.9 billion increase in the disposal of fixed assets without development plans in our Exploration and Extraction segment.

*Welfare Oil Duty*

The new Welfare Oil Duty was effective as of January 1, 2025, which consolidates the Profit-Sharing Duty, the Hydrocarbon Extraction Duty and the Hydrocarbon Exploration Duty previously payable by Petróleos Mexicanos. For more information, see "*Item 4—Information on the Company—Taxes, Duties and Other Payments to the Mexican*

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

*Government*" and Note 21 to our consolidated financial statements included herein. In 2025, Welfare Oil Duty incurred was Ps.194.6 billion.

*Financing Income* 

Financing income decreased by Ps. 3.8 billion in 2025, from Ps. 15.7 billion in 2024 to Ps. 11.9 billion in 2025. This decrease was mainly due to a reduction in interest earned on Mexican Government local bonds ("Government Bonds") issued by the Ministry of Finance and Public Credit and held by us.

*Financing Costs* 

Financing costs decreased by Ps. 8.9 billion in 2025, from Ps. 158.9 billion in 2024 to Ps. 150.0 billion in 2025, mainly due to the effect of lower debt interest costs due to an appreciation of the peso against the U.S. dollar, from Ps. 20.2683 = U.S.$1.00 as of December 31, 2024 to Ps. 17.9667 = U.S.$1.00 as of December 31, 2025 and the implementation of a liability management strategy in the second half of 2025 that resulted in a decrease of our financing costs.

*Derivative Financial Instruments Income (Cost), Net*

Derivative financial instruments (cost) decreased by Ps. 49.2 billion in 2025, from a derivative financial instruments cost of Ps. 27.6 billion in 2024 to a derivative financial instruments income of Ps. 21.6 billion in 2025, mainly as a result of (1) an increase in the fair value of our cross-currency swaps, arising from the depreciation of the U.S. dollar against other currencies in which our debt is denominated and (2) a net increase in the fair value of other derivative financial instruments, such as currency options.

*Foreign Exchange Income (Loss), Net* 

A substantial portion of our indebtedness, 88.1% as of December 31, 2025, is denominated in foreign currencies. Our exchange income, net, increased by Ps. 499.7 billion in 2025, from a net exchange loss of Ps. 304.5 billion in 2024 to a net exchange income of Ps. 195.2 billion in 2025, primarily as a result of a 11.4% appreciation of the peso relative to the U.S. dollar in 2025. Due to the fact that 100% of our revenues from exports and domestic sales are referenced to prices denominated in U.S. dollars, and only 68% of our expenses, including financing costs, are linked to U.S. dollar prices, the appreciation of the peso relative to the U.S. dollar benefits our ability to meet peso-denominated obligations. The value of the peso in U.S. dollar terms appreciated by 11.4% in 2025, from Ps. 20.2683 per U.S. $1.00 as of December 31, 2024, to Ps. 17.9667 per U.S. $1.00 as of December 31, 2025, as compared to a 19.8% depreciation in 2024.

*Profits (loss) sharing in associates*

The profit sharing in joint ventures and associates decreased by 30.0% in 2025, from a profit sharing of Ps. 1.0 billion in 2024, to a profit sharing of Ps. 0.7 billion in 2025.

*Duties, Taxes and Other* 

The Profit-Sharing Duty and other duties and taxes incurred decreased by 99.8% in 2025, from Ps. 290.3 billion in 2024, to Ps. 0.7 billion in 2025. This decrease was due to entry into force of the Welfare Oil Duty in 2025, which has consolidated the Profit-Sharing Duty and other taxes and duties previously payable by Petróleos Mexicanos. This Welfare Oil Duty is accounted for under "—*Welfare Oil Duty*" above. For more information, see "*Item 4—Information on the Company—Taxes, Duties and Other Payments to the Mexican Government*" and Note 21 to our consolidated financial statements included herein.

*Net Income/Loss* 

In 2025, we had a net loss of Ps.(81.7) billion on Ps. 1,528.5 billion in total revenues, as compared to a net loss of Ps. (780.6) billion on Ps. 1,672.7 billion in total revenues in 2024. This decrease in net loss relative to 2024 was primarily explained by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 175.0 billion decrease in cost of sales;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 45.4 billion decrease in impairment of fixed assets;

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 11.8 billion increase in other revenues;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 8.9 billion decrease in financing costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 49.2 billion decrease in the cost of derivative financial instruments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 499.7 billion increase in foreign exchange income; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 289.6 billion decrease in duties, taxes and other.

These effects were partially offset by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 144.2 billion decrease in total revenues, mainly due to a decrease in the volume of Mexican crude oil for export sales;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps.23.5 billion increase in administrative and distribution, transportation and sale expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 3.8 billion decrease in financing income;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 194.6 billion increase in Welfare Oil Duty; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 16.8 billion increase in other expenses.

*Other Comprehensive Results* 

In 2025, we had a total comprehensive (loss) of Ps. (317.3) billion, compared to a comprehensive (loss) of Ps. (487.3) billion in 2024. The improvement in comprehensive (loss) was primarily due to the net loss recognized in 2025 of Ps.(81.7) billion less than the net loss obtained in 2024, and Ps. (173.6) billion of actuarial losses recognized in 2025 relating to retirement and post-employment benefits, due to a decrease in the discount rate and return on plan assets from 11.28% as of December 31, 2024 to 9.95% as of December 31, 2025 and Ps.(62.0) billion in unfavorable currency translation effects.

Results of Operations

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B. Results of Operations of Petróleos Mexicanos, the Subsidiary Entities and the Subsidiary Companies—For the Year Ended December 31, 2024, compared to the Year Ended December 31, 2023**

*Total Revenues* 

Total revenues decreased by 2.7% or Ps. 47.3 billion in 2024, from Ps. 1,719.9 billion in 2023 to Ps. 1,672.7 billion in 2024. The decrease in total revenues was mainly due to a decrease in the volume of Mexican crude oil for export sales (Ps.90.8 billion). This decrease was partially offset by an increase in the domestic sales volume of gasoline, diesel, jet fuel and natural gas liquids (Ps. 22.4 billion), as well as an increase in foreign currency variations (Ps. 18.2 billion).

From January 1 to December 31, 2024, the weighted average Mexican export crude oil price was U.S. $70.20 per barrel, as compared to U.S. $70.59 per barrel for the same period in 2023.

*Domestic Sales* 

Domestic sales increased by 3.1% or Ps. 29.0 billion in 2024, from Ps. 948.7 billion in 2023 to Ps. 977.7 billion in 2024, mainly due to increases in the sales volume of gasoline, diesel, jet fuel, and natural gas liquids. Domestic sales of petroleum products increased by 3.2% in 2024, from Ps. 859.9 billion in 2023 to Ps. 887.5 billion in 2024, mainly due to a 3.9% increase in the sales volume of gasoline, a 2.5% increase in the sales volume of diesel, a 9.9% increase in the sales volume of jet fuel and a 4.9% increase in the sales volume of natural gas liquids.

Domestic sales of natural gas decreased by 17.9% in 2024, from Ps. 23.5 billion in 2023 to Ps. 19.3 billion in 2024, primarily due to a 13.7% decrease in its sales volume.

Domestic sales of LPG increased by 10.3% in 2024, from Ps. 43.9 billion in 2023 to Ps. 48.4 billion in 2024. This increase was primarily due to a 5.3% increase in its average sales price.

*Export Sales* 

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

Export sales decreased by 9.9% in peso terms in 2024 (with U.S. dollar-denominated export revenues translated to pesos at the exchange rate on the date of the corresponding export sale) from Ps. 767.6 billion in 2023 to Ps. 691.9 billion in 2024. This decrease was mainly due to a 21.7% decrease in the sales volume of Mexican crude oil export in 2024, compared to 2023. From January 1 to December 31, 2024, the weighted average Mexican export crude oil price was U.S. $70.20 per barrel, as compared to U.S. $70.59 per barrel for the same period in 2023. Export sales of Deer Park decreased by 4.2% in 2024, from Ps. 173.2 billion in 2023 to Ps. 166.0 billion in 2024. This decrease was mainly due to a 40.6% decrease in the sales volume of gasoline.

Excluding the trading activities of the Trading Companies and Deer Park (in order to show only the amount of export sales related to the subsidiary entities), export sales by the subsidiary entities to third parties decreased by 12.4% in peso terms, from Ps. 558.2 billion in 2023 to Ps. 488.8 billion in 2024. In U.S. dollar terms, excluding the trading activities of the Trading Companies, total export sales (which are U.S. dollar denominated) decreased by 15.0% in 2024, from U.S. $30.7 billion in 2023 to U.S. $26.1 billion in 2024. This was primarily due to 21.7% decrease in the sales volume of Mexican export crude oil in 2024, compared to 2023. The trading and export activities of the Trading Companies and Deer Park generated additional revenues of Ps. 203.1 billion in 2024, 3.0% lower in peso terms than the Ps. 209.3 billion generated in 2023. This decrease was mainly due to lower export sales of Deer Park by decreases in the sales volume of gasoline.

Crude oil and condensate export sales accounted for 54.6% of total export sales in 2024, as compared to 61.3% in 2023. These crude oil and condensate sales decreased in peso terms by 19.6% in 2024, from Ps. 470.5 billion in 2023 to Ps. 378.1 billion in 2024 and in U.S. dollar terms by 22.2%, from U.S. $26.6 billion in 2023 to U.S. $20.7 billion in 2024. The weighted average Mexican crude oil export price in 2024 was 0.6% lower than the weighted average price of U.S. $70.59 per barrel in 2023.

Export sales of petroleum products, including natural gas and natural gas liquids, by our industrial transformation segment increased from 9.6% of total export sales in 2023 to 12.9% of those export sales in 2024. Export sales of petroleum products, including products derived from natural gas and natural gas liquids, increased by 20.1%, from Ps. 74.0 billion in 2023 to Ps. 88.9 billion in 2024, primarily due to a increase in the sales volume of fuel oil.

Export sales of petrochemical products (including certain byproducts of the petrochemical process) increased by Ps. 0.9 billion in 2024, from Ps. 3.0 billion in 2023 to Ps. 3.9 billion in 2024, primarily due to a increase in volume of sales by Grupo Fertinal, S.A. de C.V.

*Services Income* 

Services income decreased by 14.6% in 2024, from Ps. 3.7 billion in 2023 to Ps. 3.2 billion in 2024, primarily as a result of a decrease in transportation services provided by Pemex Industrial Transformation and Pemex Logistics to third parties.

*Cost of Sales* 

Cost of sales increased by 4.0%, from Ps. 1,380.7 billion in 2023 to Ps. 1,435.5 billion in 2024. This increase was mainly due to: (1) a Ps. 82.7 billion increase in operating expenses primarily due to the IEPS tax and material and spare parts, (2) a Ps. 23.0 billion increase in maintenance costs, (3) a Ps. 8.9 billion increase in the amortization of wells and (4) a Ps. 7.2 billion recurring expense related to unsuccessful wells. This increase was partially offset by (1) an decrease of Ps. 90.0 billion in import purchases, primarily due to a decrease in volume of Magna gasoline, diesel and natural gas and a decrease in the purchase price of imported products.

*Impairment of Wells, Pipelines, Properties, Plant and Equipment, net*

Impairment of wells, pipelines, properties, plant and equipment increased by Ps. 24.7 billion in 2024, from a net impairment of Ps. 28.8 billion in 2023 to a net impairment of Ps. 53.5 billion in 2024. This net impairment was primarily due to Ps. 78.0 billion in the cash generating units of Pemex Industrial Transformation, mainly due to the decrease in sale prices and an increase in the discount rate of CGUs as refined products from 13.68% as of December 31, 2023 to 14.75% as of December 31, 2024. This was partially offset by a Ps. 24.0 billion net reversal of impairment in the cash-generating units of Pemex Exploration and Production, mainly due to a positive effect of exchange rate from Ps.16.9220 = U.S.$1.00 as of December 31, 2023 to Ps.20.2683 = U.S$1.00 as of December 31, 2024 and an increase in crude oil prices and condensate products.

*Administrative Expenses and Distribution, Transportation and Sale Expenses* 

Administrative expenses and distribution, transportation and sale expenses increased by Ps. 4.5 billion in 2024, from Ps. 182.8 billion in 2023 to Ps. 187.3 billion in 2024, mainly due to increases in net periodic cost of employee benefits, personnel services and maintenance expenses.

*Impairment losses on trade receivables*

Impairment losses on trade receivables increased by Ps. 12.3 billion in 2024, from Ps. 3.1 billion in 2023 to Ps. 15.4 billion in 2024, mainly due to an increase in uncollectible export accounts due to the lack of a reasonable expectation of recovery.

*Other Revenues* 

Other revenues increased by Ps. 2.9 billion in 2024, from Ps. 15.6 billion in 2023 to Ps. 18.5 billion in 2024. This increase was mainly attributable to Ps. 3.1 billion in income from the recovery of insurance claims related to the fire on the E-Ku-A2 platform of the Ku Maloob-Zaap production asset in 2001.

*Other Expenses* 

Other expenses decreased by Ps. 1.7 billion in 2024, from Ps. 17.2 billion in 2023 to Ps. 15.5 billion in 2024. This decrease was mainly due to a Ps. 6.5 billion reduction in the disposal of fixed assets without development plans in Pemex Exploration and Production and was partially offset by an increase of Ps. 4.2 billion in penalties.

*Financing Income* 

Financing income decreased by Ps. 2.5 billion in 2024, from Ps. 18.2 billion in 2023 to Ps. 15.7 billion in 2024. This decrease was mainly due to a reduction in interest earned on Mexican Government local bonds ("Government Bonds") issued by the Ministry of Finance and Public Credit and held by us.

*Financing Costs* 

Financing costs increased by Ps. 6.7 billion in 2024, from Ps. 152.2 billion in 2023 to Ps. 158.9 billion in 2024, mainly due to the effect of the average exchange rate, reflecting a 3.0% depreciation of the peso against the U.S. dollar as of December 31, 2024, compared to the same period in 2023.

*Derivative Financial Instruments Income (Cost), Net*

Derivative financial instruments cost increased by Ps. 28.3 billion in 2024, from a derivative financial instruments income of Ps. 0.7 billion in 2023 to a derivative financial instruments cost of Ps. 27.6 billion in 2024, mainly as a result of (1) an increase in the fair value of our cross-currency swaps, arising from the appreciation of the U.S. dollar against other currencies in which our debt is denominated and (2) a net increase in the fair value of other derivative financial instruments, such as currency options.

*Foreign Exchange Income (Loss), Net* 

A substantial portion of our indebtedness, 86.1% as of December 31, 2024, is denominated in foreign currencies. Our exchange income, net, decreased by Ps. 542.5 billion in 2024, from a net exchange income of Ps. 238.1 billion in 2023 to a net exchange loss of Ps. 304.5 billion in 2024, primarily as a result of a 19.8% depreciation of the peso relative to the U.S. dollar in 2024. Due to the fact that 100% of our revenues from exports and domestic sales are referenced to prices denominated in U.S. dollars, and only 68% of our expenses, including financing costs, are linked to U.S. dollar prices, the depreciation of the peso relative to the U.S. dollar adversely affects our ability to meet peso-denominated obligations. The value of the peso in U.S. dollar terms depreciated by 19.8% in 2024, from Ps. 16.9220 per U.S. $1.00 as of December 31, 2023, to Ps. 20.2683 per U.S. $1.00 as of December 31, 2024, as compared to a 12.8% appreciation in 2023.

*Profits (loss) sharing in joint ventures and associates*

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

The profit sharing in joint ventures and associates increased by 150.0% in 2024, from a profit sharing of Ps. 0.4 billion in 2023, to a profit sharing of Ps. 1.0 billion in 2024.

*Duties, Taxes and Other* 

The Profit-Sharing Duty and other duties and taxes incurred increased by 31.9% in 2024, from Ps. 220.0 billion in 2023, to Ps. 290.3 billion in 2024. This increase was mainly due to the cancellation of deferred tax assets totaling Ps. 159.9 billion, pursuant to our transformation into a state-owned public company on November 1, 2024, which exempted us from the Income Tax Law. This increase in taxes, duties and other was partially offset by a decrease of Ps. 86.6 billion in the Profit-Sharing Duty. The reduction in the Profit-Sharing Duty, which was primarily driven by a 0.6% decrease in the weighted average export price of Mexican crude oil—from an average of U.S.$70.59 per barrel in 2023 to U.S.$70.20 per barrel in 2024—the suspension of the Profit-Sharing Duty for the months of January, May, June, and July 2024, and a reduction in the tax rate from 40% in 2023 to 30% in 2024. Duties and taxes represented 12.8% and 17.4% of total sales in 2023 and 2024, respectively.

*Net Income/Loss* 

In 2024, we had a net loss of Ps.(780.6) billion on Ps. 1,672.7 billion in total revenues, as compared to a net income of Ps. 8.2 billion on Ps. 1,719.9 billion in total revenues in 2023. This decrease in net income relative to 2023 was primarily explained by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 47.3 billion decrease in total revenues, mainly due to a decrease in the volume of Mexican crude oil for export sales;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 24.7 billion increase in impairment of fixed assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 54.8 billion increase in cost of sales;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 11.5 billion increase in impairment losses on trade receivables;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 9.1 billion increase in administrative expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 6.7 billion increase in financing costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 28.3 billion increase in the cost of derivative financial instruments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 542.5 billion increase in exchange losses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a Ps. 70.2 billion increase in taxes and other duties.

*Other Comprehensive Results* 

In 2024, we had a total comprehensive (loss) of Ps. (487.3) billion, compared to a comprehensive (loss) of Ps. (50.8) billion in 2023. This deterioration in comprehensive (loss) was primarily due to the net loss recognized in 2024 of Ps.(780.6) billion, and was partially offset by Ps. 203.2 billion of actuarial gains recognized in 2024 relating to retirement and post-employment benefits, which were due to an increase in the discount rate and return on plan assets from 9.42% as of December 31, 2023 to 11.28% as of December 31, 2024 and Ps.90.1 billion in favorable currency translation effects.

**Liquidity and Capital Resources** 

*Overview*

During 2025, our liquidity position increased 152.0% due to higher cash and cash equivalents. Under the definition of liquidity as funds available under our lines of credit, as well as cash and cash equivalents, our liquidity position was Ps.236.9 billion as of December 31, 2025, which represented an increase of Ps.142.9 billion from our Ps.94.0 billion position as of December 31, 2024.

Our principal use of funds in 2025 was the payment of debt maturities and capital expenditures. We serviced our debt maturities primarily with Ps.891.2 billion from borrowings and with Ps.395.3 billion received in equity contributions from the Mexican Government.

During 2025, works in progress for the construction of the Olmeca refinery in Dos Bocas, Paraíso, Tabasco, including payments made in advance to contractors, decreased by Ps.0.2 billion, from Ps.4.0 billion as of December 31, 2024 to Ps.3.8 billion as of December 31, 2025.

As of December 31, 2025, we owed our suppliers Ps.436.7 billion, a 13.7% decrease as compared to the Ps.506.0 billion owed as of December 31, 2024. As of March 31, 2026, we have paid approximately 38.6% of the total outstanding balance due to suppliers and contractors as of December 31, 2025. The average number of days outstanding of our accounts payable increased by 3.4%, from 265 days as of December 31, 2024, to 274 days as of December 31, 2025.

Despite these obligations, we believe net cash flows from our operating and financing activities, available cash from our available credit lines, equity contributions and cash and cash equivalents, will be sufficient to meet our working capital, debt service and capital expenditure requirements in 2026. Our ability to raise cash from financing activities and contributions from the Mexican Government involves matters outside of our management's control and there can be no assurance that such efforts may be successful.

The Ley de Ingresos de la Federación para el Ejercicio Fiscal (Federal Revenue Law) applicable to us as of January 1, 2026, provides for our incurrence of up to Ps.261.6 billion of net indebtedness through a combination of domestic and international capital markets offerings and borrowings from domestic and international financial institutions. The Federal Revenue Law applicable to us during 2025 provided for our incurrence of up to Ps.245.4 billion of net indebtedness through a combination of domestic and international capital markets offerings and borrowings from domestic and international financial institutions

As of December 31, 2025, our total indebtedness, including accrued interest, was Ps. 1,531.3 billion (U.S. $85.2 billion) in nominal terms, which represented a 22.6% decrease compared to our total indebtedness, including accrued interest, of Ps. 1,978.8 billion as of December 31, 2024. Ps. 588.7 billion (U.S.$32.8 billion) of our existing debt as of December 31, 2025, or 38.4%, is scheduled to mature in the next three years. Our working capital increased from a negative working capital of Ps.768.0 billion as of December 31, 2024, to a negative working capital of Ps.530.5 billion (U.S.$29.5 billion) as of December 31, 2025. Our level of debt may increase further in the short or medium term as a result of new financing activities or future depreciation of the Mexican peso as compared to the U.S. dollar, which may have an adverse effect on our financial condition, results of operations and liquidity position. To service our debt, we have relied and may continue to rely on a combination of cash flow from operations, equity capital contributions from the Mexican Government, drawdowns under our available credit facilities and refinancing our existing indebtedness and repurchase transactions. See Note 22-F to our consolidated financial statements included herein for more information related to the actions we are taking to improve our financial position.

We currently have a substantial amount of employee benefits liabilities. Benefits to employees were 35.6% of our total liabilities as of December 31, 2025 and any adjustments recorded will affect our net income and/or comprehensive net income during the corresponding period. As of December 31, 2025, our substantial unfunded reserve for retirement pensions and seniority premiums was Ps.1,470.1 billion. For more information on our Employee Benefits and Benefit Pension Plan, see Note 19 to our consolidated financial statements included herein.

Credit ratings address our creditworthiness and the likelihood of timely payment of our long-term debt securities. Ratings are not a recommendation to purchase, hold or sell securities and may be changed, suspended or withdrawn at any time. Our current ratings and the rating outlooks depend, in part, on economic conditions and other factors that affect credit risk and are outside our control, as well as assessments of the creditworthiness of Mexico.

Ratings actions related to us that occurred in 2025 and as of the date of this annual report include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On August 1, 2025, Fitch Ratings upgraded PEMEX's long-term local and foreign currency issuer default to "BB" from "B+". Fitch Ratings also removed its Rating Watch Positive and upgraded the rating of PEMEX's senior unsecured notes outstanding to "BB" from "B+"/"RR4 with a stable outlook."

Downgrades of our credit ratings, particularly those below investment grade, may have material adverse consequences on our ability to access the financial markets and/or our cost of financing. In turn, this could significantly harm our ability to meet our existing obligations, financial condition and results of operations. See *"Item 3—Risk Factors—Risk Factors Related to Our Operations—Downgrades in our credit ratings could negatively impact our access to the financial markets and cost of financing"* above.

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

If such constraints occur at a time when our cash flow from operations is less than the resources necessary to meet our debt service obligations, in order to provide additional liquidity to our operations, we could be forced to further reduce our planned capital expenditures, implement further austerity measures and/or utilize alternative financing mechanisms that do not constitute public debt. A reduction in our capital expenditure program could adversely affect our financial condition and results of operations. Additionally, such measures may not be sufficient to permit us to meet our obligations.

*Equity Structure and Mexican Government Contributions* 

As of December 31, 2025, our total equity (deficit) was negative Ps.1,905.8 billion and our total capitalization (as long-term debt plus equity) totaled negative Ps.719.7 billion. During 2025, our total equity (deficit) decreased from negative Ps.1,983.8 billion as of December 31, 2024, to negative Ps.1,905.8 billion as of December 31, 2025, primarily by Ps.395.3 billion in equity contributions from the Mexican Government. This amount was partially offset as a result of our net loss for the year of Ps.81.7 billion, Ps.173.6 billion in actuarial losses on employee benefits and Ps.62.0 billion in negative currency translation effects. Under the *Ley de Concursos Mercantiles* (the Commercial Bankruptcy Law), Petróleos Mexicanos cannot be subject to bankruptcy proceedings. In addition, our current financing agreements do not include financial covenants or events of default that would be triggered as a result of our having negative equity.

During 2025 and 2024, we received Ps.395.3 billion and Ps.156.5 billion, respectively in capital contributions from the Mexican Government. See Note 22 to our consolidated financial statements included herein for more information.

As of December 31, 2025 and 2024, the total amount of contributions in the form of Certificates of Contribution "A" was Ps.395.3 billion and Ps.156.5 billion, respectively. As of December 31, 2025 and 2024, the balance of the form of Certificates of Contribution "A" was Ps.1,748.0 billion and Ps.1,352.7 billion, respectively.

During the first quarter of 2026, we received equity contributions from the Mexican Government of Ps.58.3 billion.

*Cash Flows from Operating, Financing and Investing Activities* 

During 2025, net cash flows from operating activities totaled Ps.155.2 billion, as compared to Ps.322.9 billion in 2024. During 2025, our net cash flows used in investing activities totaled Ps.(235.3) billion, as compared to net cash flows used in investing activities of Ps.(272.3) billion in 2024. Our net cash flows from financing activities totaled Ps.167.4 billion in 2025, as compared to net cash flows used in financing activities of Ps.(59.7) billion in 2024.

On December 31, 2025, our cash and cash equivalents totaled Ps.162.7 billion, as compared to Ps.88.8 billion at December 31, 2024. See Note 9 to our consolidated financial statements included herein for more information about our cash and cash equivalents.

*Investment Policies* 

Our Finance and Treasury Department aims to maintain financial resources sufficient to meet our payment commitments and those of the subsidiary companies when applicable, as well as a comprehensive, consolidated cash position and related projections in anticipation of such commitments.

Our investment policies attempt to take advantage of favorable market conditions by accessing the most favorable terms offered to us by financial institutions. Investments of financial resources by our Finance and Treasury Department are made in accordance with the following policies:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*(i) Investment of Financial Resources in Mexican Pesos*

In connection with investments of financial resources in Mexican pesos, we are obligated, during the structuring and development phase of our financial transactions, to observe and comply with the investment guidelines for resources in pesos that were approved by our Financial Resources Committee on July 24, 2017, as modified from time to time. We may only invest in the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)securities issued or guaranteed by the Mexican Government;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)securities issued by *Sociedades Nacionales de Crédito* (National Credit Societies), the balance of which may not exceed 50% of our cash and cash equivalents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)repurchase agreements that use securities issued or guaranteed by the Mexican Government;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)time deposits with major financial institutions, the balance of which may not exceed 30% of our cash and cash equivalents; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)shares of mutual funds whose investments are limited to securities issued or guaranteed by the Mexican Government.

In addition to the restrictions listed above, demand deposit accounts must be traded with financial institutions that maintain, at a minimum, the following credit ratings as issued by the applicable rating agency:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*(ii) Investments of Financial Resources in Dollars* 

Investment of financial resources in dollars must meet our operational and strategic requirements and must be previously approved by *Banco de México* on a case-by-case basis.

*Operational Currencies* 

The main currencies for investing cash and cash equivalents are pesos and dollars. Similarly, we generate revenues from the domestic and international sales of our products in those two currencies and our expenses, including those relating to our debt service, are payable in these two currencies.

*2025 Financing Activities*

Financing activities as of December 31, 2025 and 2024, as well as those between January 1, 2026 and the date of this annual report are disclosed in Notes 15 and 28 to our consolidated financial statements included herein.

*Commitments for Capital Expenditures and Sources of Funding*

Our capital expenditures for 2025 were Ps. 139,934 million, and we have budgeted Ps. 132,007 million for capital expenditures in 2026. Both figures exclude amounts for non-capitalizable maintenance. For an overview of current capital expenditure commitments, see "*Item 4—Information on the Company—History and Development—Capital Expenditures*" and the "*Capital Expenditures and Budget*" sections for each our activities in Item 4. The amount of our aggregate capital expenditures commitments for 2026 remains subject to adjustment by the Mexican Government.

Our current commitments for capital expenditures have fluctuated in recent years as compared to previous years. Based on past experience, we expect to generate sufficient funds for our working capital, capital expenditures and investments through:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cash flow generated by operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the renewal of existing lines of credit and the entering into of new lines of credit from international and local commercial banks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the issuance of *certificados bursátiles* (peso-denominated publicly traded notes) in the Mexican market; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other financing activities that do not constitute public debt.

We may, if necessary, issue new debt securities in U.S. dollars, Japanese yen, euros, pounds sterling or Swiss francs, among other currencies; these securities may be issued with fixed or floating rates and with maturities of one or more years, including perpetual debt securities, depending on market conditions and funding requirements. We may issue securities in the Mexican domestic market, these securities may vary in tenor, amount and type of interest rate. Commercial bank syndicated loans may be established with single or multiple tranches with varying maturities. Bilateral loans may vary in tenor and range, which may be of one year or more. Finally, we may consider the implementation and development of alternative financing mechanisms that do not constitute public debt. See also "*—Financing Activities*" below.

**Results of Operations by Business Segment**

The following tables present the condensed financial information by our business segments, after elimination of unrealized intersegment gain (loss), and include only select line items. The columns before intersegment eliminations include unconsolidated figures. As a result, the line items presented below may not total. These reporting segments are those which our management evaluates in its analysis and on which it bases its decision-making. These reporting segments are presented in PEMEX's reporting currency in millions of Mexican pesos.

As a result of the recent energy reform, we have undergone a corporate reorganization pursuant to which our subsidiary entities were dissolved and their operations were assumed by Petróleos Mexicanos and reorganized into new business segments. Accordingly, the results of the business segments presented as of and for the year ended December 31, 2025 reflect different business segments from those presented as of and for the years ended December 31, 2024 and 2023.

For the year ended December 31, 2025, segment information is presented in accordance with our new organizational structure as described under "*Item 4—Information on the Company—History and Development—Recent Energy Reform*." The segment information for the years ended December 31, 2024 and 2023 is presented under the segment structure that existed in those years and is not directly comparable to the 2025 segment information. A reclassification of 2024 and 2023 segment information to conform to the current structure was not practicable because the prior organizational structure did not track financial information on the basis of the current business segments. Similarly, a presentation of 2025 segment information under the prior segment structure is not practicable because, following the dissolution of the subsidiary entities and the reorganization of their operations, financial information is no longer tracked or available on the basis of the prior business segments.

*Financial Information by Business Segment*

***Research and development***

Our research and development efforts in the Mexican energy sector have evolved from an approach focused on the development of technological capabilities and institutional collaboration to a structured model governed by federal regulatory frameworks, while maintaining continuity in strategic engagement with public research centers and specialized organizations.

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

Our research and development strategy is oriented toward the development of specialized technologies that are not available in the international market and on the development of highly specialized human resources in the oil industry, with the objective of addressing technological needs in exploration, production, refining, and petroleum products.

Created in 1965, the Mexican Petroleum Institute is a public research organization under the Ministry of Energy that is administered by the Mexican Government and has its own legal entity and resources, as well as technical, operative and administrative autonomy with respect to its decisions. The Mexican Petroleum Institute is the only public research center in Mexico that has carried out research, technological development, innovation, process and products improvement, as well as offered high value technological services focused on process optimization in hydrocarbon exploration and production, industrial transformation, and national and international commercialization.

In addition to our close coordination with the Mexican Petroleum Institute, we have established an active collaboration model with various research institutions in Mexico, including those that are part of the Sistema Nacional de Centros Públicos de Investigación (National System of Public Research Centers), including the *Centro de Investigación Científica y de Educación Superior de Ensenada* (Ensenada Center for Scientific Research and Higher Education, or "CICESE"), *Centro de Tecnología Avanzada* (Advanced Technology Center, or "CIATEQ"), *Centro de Ingeniería y Desarrollo Industrial* (Center for Engineering and Industrial Development, or "CIDESI") and *Instituto Potosino de Investigación Científica y Tecnológica* (Institute for Scientific and Technological Research, or "IPICYT"), among others. These collaborations contribute to technological development, talent formation, and the generation of scientific knowledge applied to the hydrocarbons sector.

The new guidelines issued in March 2025 by the Ministry of Energy for the administration and operation of scientific research, technological development, and innovation activities in hydrocarbons, as well as the guidelines of Budgetary Program F003 "National Strategic Programs for Science, Technology and Linkages with the Social, Public and Private Sectors," issued by the *Secretaría de Ciencia, Humanidades, Tecnología e Innovación* (Ministry of Science, Humanities, Technology and Innovation), introduce a framework for governance, regulation, and institutional oversight in the management of research and development projects, aligned with federal public policies on science, technology, and innovation.

Collectively, the integration of these guidelines reflects an evolution toward a technology management model that combines continuity in institutional collaboration with research centers and the strengthening of regulatory and governance frameworks, enabling us to consolidate technological capabilities, ensure the traceability of its projects, and maximize the strategic value of innovation in the hydrocarbons sector.

The Mexican Government representatives that serve as members of the boards of directors of Petróleos Mexicanos may be removed at the discretion of the President of Mexico.

Source: Petróleos Mexicanos and the subsidiary companies as of December 31, 2025 and Petróleos Mexicanos, its subsidiary companies and former subsidiary entities as of December 31, 2024, 2023, 2022 and 2021.

As of December 31, 2025, the Petroleum Workers' Union represented 79.3% of the work force of Petróleos Mexicanos and the productive state-owned subsidiaries. The members of the Petroleum Workers' Union are PEMEX employees and they elect their own leadership from among their ranks. Our relationship with our employees is regulated by the *Ley Federal de Trabajo* (which we refer to as the Federal Labor Law), a collective bargaining agreement between Petróleos Mexicanos and the Petroleum Workers' Union and the *Reglamento de Trabajo del Personal de Confianza de Petróleos Mexicanos y Empresas Subsidiarias* (Employment Regulation for White Collar Employees of PEMEX and Subsidiary Entities). The collective bargaining agreement is subject to renegotiation every two years, although salaries are reviewed annually. Since the Petroleum Workers' Union was officially established in 1938, we have not experienced labor strikes; we have experienced work stoppages for short periods of time, but none of these stoppages had a material adverse effect on our operations.

On September 22, 2025, Petróleos Mexicanos and the Petroleum Workers' Union amended their collective bargaining agreement. The amendment became effective on August 1, 2025. The amended agreement provides for a 4.5% increase in wages and will regulate their labor relations until July 31, 2026

In accordance with the Federal Labor Law and the collective bargaining agreement in effect as of December 31, 2025, Petróleos Mexicanos and the productive state-owned subsidiaries are under an obligation to pay seniority premiums to retiring employees and pensions to retired employees, as well as death benefits and pensions to certain survivors of retired employees. Retirees are entitled to receive increases in their pensions, of at least the increase in NCPI from August 2025 to July 2026 and up to a maximum of the increase granted to salaries, whenever salary increases are granted to current employees. We also provide health and medical benefits to employees, retired employees and their beneficiaries and, subject to our overall budgetary constraints, we provide an interest-rate subsidy on employees' mortgage loans.

As of December 31, 2025, the Mexican Government local bonds (the "Government Bonds") consist of 1 series of development bonds (D Bonds, M Bonds and UDI Bonds) issued by the Ministry of Finance and Public Credit with maturity in 2026, at nominal value of Ps.21,419,618. The resources from the Government Bonds will be exclusively transferred to the *Fondo Laboral Pemex* (Pemex Labor Fund, or "FOLAPE") for the obligation payment related to its pension and retirement plan obligation. For further information about Government Bonds, see Note 14-A to our consolidated financial statements included herein.

As of November 11, 2015, pursuant to an agreement with the Petroleum Workers' Union, the retirement age for employees with less than 15 years of service is 60 (compared to 55 for employees with more than 15 years of service). Employees must serve for at least 30 years in order to be eligible to receive full retirement benefits. New employees hired as of that date receive individual defined contributions retirement plans. Employees who began serving prior to that date are permitted and incentivized to opt into the defined contributions retirement plans from their existing defined benefits retirement plans.

On December 24, 2015, the Ministry of Finance and Public Credit published in the Official Gazette of the Federation the General provisions regarding the assumption by the Mexican Government of the payment obligations related to pensions and retirement plans of Petróleos Mexicanos and its productive state-owned subsidiaries. On August 3, 2016, the Ministry of Finance and Public Credit informed us that the Mexican Government would assume Ps.184.2 billion in payment liabilities related to our pensions and retirement plans, and accordingly replaced the Ps.50.0 billion promissory note issued to us on December 24, 2015 with Ps.184.2 billion in promissory notes.

On November 5, 1997, the Ministry of Finance and Public Credit and the Board of Directors of Petróleos Mexicanos authorized the formation of a trust called the Pemex Labor Fund. This fund is a vehicle to fund labor liabilities, current pension payments and seniority premiums. We have designed a contribution plan to increase the funds held in this trust and to continue paying labor liabilities and pensions. Our contributions to the plan assets for our retirement benefits totaled Ps. 87,848.3 million in 2025 and Ps.83,177 million in 2024. As of December 31, 2025 and 2024, the balance of the Pemex Labor Fund was Ps.2,450.4 million and Ps.111.4 million, respectively.

**Item 7.&nbsp;&nbsp;&nbsp;&nbsp;Major Shareholders and Related Party Transactions**

**Major Shareholders** 

Petróleos Mexicanos has no shareholders because it is a wholly state-owned public company controlled by the Mexican Government. The Mexican Government incorporates our annual budget and financing program into its budget, which must be approved by the Chamber of Deputies each year. Any adjustment proposed by the Board of Directors of Petróleos Mexicanos to change our annual financial balance goal or increase the limit on our wage and salary expenditures budget or our financing program must be approved by the Chamber of Deputies. See "*Item 4—Information on the Company—General Regulatory Framework*" for more information about the Mexican Government's authority with respect to our budget. Our operations in the oil and gas sector are also regulated by the Mexican Government and its ministries.

Pursuant to the 2025 Petróleos Mexicanos Law, the number of seats on the Board of Directors of Petróleos Mexicanos has been reduced from ten to eight. For more information about recent changes to our corporate governance structure, see "*Special Note Regarding Mexican Energy Reform*" and "*Item 4—Information on the Company—History and Development—Recent Energy Reform.*" As of the date of this annual report, Mexican Government officials hold five of eight seats on the Board of Directors of Petróleos Mexicanos, while the additional three seats are held by independent members appointed by the President of Mexico and ratified by a two-thirds majority in the Mexican Senate. As of the date of this report, the General Director of Petróleos Mexicanos was, and as of the date of this annual report continues to be, a member of the President of Mexico's cabinet. See also "Item 3—Key Information—Risk Factors—Risk Factors Related to our Relationship with the Mexican Government."

**Related Party Transactions** 

Directors and employees of Petróleos Mexicanos are subject to regulations addressing conflicts of interest, including the 2025 Petróleos Mexicanos Law, *Ley Federal de Responsabilidades Administrativas de los Servidores Públicos* (Federal Law of Administrative Responsibilities of Public Officials) and the Anti-corruption Policies and Guidelines for Petróleos Mexicanos, its productive subsidiary entities and, where applicable, affiliated companies. Under these provisions, directors and employees of Petróleos Mexicanos are obligated to "recuse themselves from intervening in any way in the attention to, processing or resolution of matters in which they might have personal, family or business interest, including those where some benefit can result for themselves, their spouse, blood or affinity relatives up to the fourth degree, or civil relatives, or for third parties with which they have professional, labor or business relations, or for partners or partnerships where the public officials or the persons referred above are or have been members thereof."

The Board of Directors of Petróleos Mexicanos, including the independent members who are not public officials, are subject to the duties of loyalty and diligence. In accordance with the 2025 Petróleos Mexicanos Law, an independent member of the Board of Directors of Petróleos Mexicanos may be removed from his or her position for, among other causes: (1) utilizing for personal benefit or for the benefit of any third party the information made available to him or her in connection with the exercise of his or her duties as a board member; (2) disclosing such information in violation of applicable law; or (3) not recusing him or herself from discussion of and voting on matters in respect of which he or she has a conflict of interest. A member of the Board of Directors of Petróleos Mexicanos who acts in contravention of the 2025 Petróleos Mexicanos Law may be held liable for any damages that he or she caused to Petróleos Mexicanos or any of its affiliated companies.

As an employee benefit, we offer salary advances to all of our eligible Petroleum Workers' Union and non-union workers, including our executive officers, pursuant to the programs set forth in the collective bargaining agreement and in the Employment Regulation of White Collar Employees of Petróleos Mexicanos. The salary advances, which are non-interest bearing, are offered to each eligible employee in an amount up to a maximum of four months' salary and are repaid through salary deductions in equal installments over a period of either one or two years, as elected by the employee. Most of our employees take advantage of this benefit. The largest amount of salary advances outstanding to executive officers at any one time during 2025 was Ps. 0.9 million. As of March 31, 2026, the aggregate amount of salary advances outstanding to our executive officers was Ps.0.1 million. For further information about compensation of Directors and Officers, see Note 25 to our consolidated financial statements included herein.

Additionally, Ms. Emilia Esther Calleja Alor, one of the members of the Board of Directors of Petróleos Mexicanos, is also the Chief Executive Officer of CFE, and was appointed as a member of the Board of Directors of Petróleos Mexicanos in accordance with Article 18 Fraction V of the 2025 Petróleos Mexicanos Law. CFE has entered into several purchase agreements with Petróleos Mexicanos (in the Industrial Processes and Energy Transformation segments, formerly Pemex Industrial Transformation), which we consider to be a related party transaction. For further information about this related party transaction, see Note 25 to our consolidated financial statements included herein.

**Item 8.&nbsp;&nbsp;&nbsp;&nbsp;Financial Information Consolidated Statements and Other Financial Information** 

See Item 18. "Financial Statements."

**Legal Proceedings** 

*Labor-Related Proceedings* 

We are a party to various legal actions involving labor claims of former and present employees. These labor disputes relate to severance payments, life insurance benefits, extensions of labor contracts, level of wages, improper termination and employee housing. We do not expect these lawsuits to have a material adverse effect on our financial condition or future results of operations.

For information on our negotiations with the Petroleum Workers' Union and collective bargaining agreements, see "*Item 6—Directors, Senior Management and Employees—Employees*."

*Governmental Investigations and Other Monitoring Activities* 

The *Auditoría Superior de la Federación* (Superior Audit Office of the Federation, or the "ASF"), pursuant to the 2025 Petróleos Mexicanos Law, has the authority to annually review Petróleos Mexicanos. The ASF reports directly to the Mexican Congress and prepares reports of its observations based on its review. These reports are subject to our analysis and, if necessary, our clarification and explanation of any issues raised during the audit. Discrepancies in amounts spent may expose our officials, as public servants, to legal sanctions. However, in most instances, any observed issues are clarified and resolved.

The public officers of Petróleos Mexicanos are subject to the General Law of Administrative Liabilities. The Liabilities Unit at Petróleos Mexicanos, which is part of the *Secretaría Anticorrupción y Buen Gobierno* (Ministry of Anti-Corruption and Good Governance, or "SABG"), is responsible for receiving complaints and investigating violations of the General Law of Administrative Liabilities, conducting investigations and administrative liability procedures, as well as imposing administrative penalties in accordance with applicable law.

We are subject to Mexican and international anti-corruption, anti-bribery, anti-money laundering and anti-terrorist financing laws. We maintain a corporate compliance program that includes policies and processes intended to comply with these laws, such as our internal control system. Our internal control system aims to prevent risks, anticipate any weaknesses arising from our operations or internal control over financial reporting and promote information exchange and communication. However, we are subject to the risk that our management, employees, contractors or any person doing business with us may (i) engage in fraudulent activity, corruption or bribery, (ii) circumvent or override our internal controls and procedures or (iii) misappropriate or manipulate our assets to our detriment. This risk is heightened by the fact that we have a large number of complex and significant contracts with local and foreign third parties. Although we have systems and internal policies in place for identifying, monitoring and mitigating these risks, such systems and policies have failed in the past and may not be effective in the future. Furthermore, we cannot ensure that these compliance policies and

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

processes will prevent intentional or reckless or negligent acts committed by our management, employees, contractors or any person doing business with us. See "*Item 3—Key Information—Risk Factors—Risk Factors Related to Our Operations—We are subject to Mexican and international anti-corruption, anti-bribery, anti-money laundering or similar laws. Our failure to comply with these laws could result in penalties, which could harm our reputation and have an adverse effect on our business, results of operations and financial condition.*"

As a matter of policy, we cooperate with investigations by Mexican, U.S. and other government authorities from time to time. In addition, we periodically monitor our compliance with applicable laws and regulations to enhance our compliance program. Further, the SABG conducts administrative reviews and, in the past, it and other government entities have brought proceedings against our senior managers and employees for activities detrimental to our business. We are committed to collaborating with competent authorities to pursue and combat illicit activities and to protect our interests and reputation. We have a zero-tolerance policy regarding acts of bribery and corruption.

*Actions Against the Illicit Market in Fuels* 

The illicit market in fuels in Mexico primarily involves the theft, adulteration and illegal transport, storage, distribution and commercialization of the hydrocarbons that we and other companies produce. This criminal activity mainly consists of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Illegal tapping of our pipelines, which threatens the integrity of our pipeline system, thereby increasing the associated risks for personnel, facilities, the general population and the environment. The illegal tapping of our pipelines has caused volumetric deviations of products, explosions, loss of life, injuries, environmental damages and, in the past, material damages.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Theft and illegal trade in fuels, which reduces our revenues by the amount that would have been generated from the sale of the stolen products and reduces our net income because the production cost of stolen product is included in our cost of sales. The increase in surveillance, as well as the actions taken against illegal trade in fuels, allowed us to protect 61.0 million liters of hydrocarbons in 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Tampering with the quality of the products we produce and transport, which negatively impacts consumers and our reputation.

During 2025, we experienced an increase in theft of and illegal trade in the fuels that we produce. We estimate that the average theft of fuel amounted to approximately 19.6 thousand barrels per day in 2025, a 15.3% increase as compared to 17.0 thousand barrels per day in 2024. For the years ended December 31, 2025 and 2024, losses resulting from fuel theft amounted to Ps.23,491.4 million and Ps.20,529.1 million, respectively.

Given the sophistication and breadth of illegal networks, in recent years we have implemented several initiatives to develop a sustainable operating model to safeguard our workers, facilities, assets and values. These initiatives have sought to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Coordinate with the *Fuerzas Armadas de México* (Mexican Armed Forces) and *Guardia Nacional* (National Guard) to conduct surveillance and patrolling of the pipeline transport systems, reducing damage to their integrity, locating clandestine taps, securing assets, and consequently preventing further harm to our infrastructure, the population and the environment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Strengthen coordination and collaboration between us and government authorities, which include, among others, the *Fiscalía General de la República* (Office of the Federal Attorney General), *Secretaría de la Defensa Nacional, Secretaría de Marina- Armada de México y Guardia Nacional* (Mexican Armed Forces and the National Guard), *Procuraduría Federal del Consumidor* (Federal Consumer's Office), *Servicio de Administración Tributaria* (Tax Administration Service, or the "SAT"), state and municipal police, the *Secretaría de Seguridad y Protección Ciudadana* (Ministry of Security and Citizen Protection), the Ministry of Energy, the *Unidad de Inteligencia Financiera* (Finance Intelligence Unit), *Agencia de Seguridad, Energía y Ambiente (Security, Energy and Environmental Agency),* the National Commission of Energy and the Ministry of Finance and Public Credit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Incorporate technological solutions to support pipeline patrols and locate clandestine collection centers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Improve citizen complaint channels.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Strengthen our leak detection and pipeline monitoring systems.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increase safety in and around pipelines, ground transportation and company facilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Incorporate best practices for industrial safety, civil protection and environmental preservation in Strategic Safeguard works.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Optimize our human capital and modernize our technology.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Modernize our information systems to improve our strategic decision making and our response time.

The *Plan Conjunto de Atención a Instalaciones Estratégicas de Pemex* (Joint Plan for Attention to Strategic Facilities of Pemex), implemented in January 2019, is aimed at preventing and decreasing the illicit fuel market and envisages government actions that are channeled through general and special crime prevention and, in turn, through the strategy to combat the illicit hydrocarbon market which is part of the National Public Security Strategy implemented in this Joint Plan. During 2025 and 2024, 10,591 and 11,774 clandestine takeovers were identified and disabled, respectively, representing a decrease of 10.0% in the location of clandestine takeovers.

The principal actions of this plan are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Strengthen the security of our pipelines, land transport and facilities by establishing collaboration agreements with the Ministry of National Defense and the Mexican Armed Forces.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Strengthen our Strategic Safeguard strategy through the implementation of four principal measures related to hydrocarbon theft, transport, storage and marketing, together with an ancillary measure focused on prosecution and enforcement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increase monitoring and strategic safeguarding of our pipelines.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Report and remove personnel who have been identified as participants in illicit activities related to the theft of hydrocarbons.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Attention to facilities identified as priority such as refineries, petrochemical complexes, storage and dispatch terminals, maritime terminals and pumping and repumping stations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Strengthen fuel distribution capacity through alternative means of transportation to the pipeline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ensure the continuity and effectiveness of the operational deployment of personnel from the Strategic Safeguard Subdirectorate and the Mexican Armed Forces to enhance troop deployment for the surveillance and patrolling of our reactivated pipeline transport systems.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Evaluate 157 facilities, assigned according to the Remote Strategic Classification Program, 12 of which are classified as "AAA," 19 as "AA" and 126 as "A." This classification is based on the importance of the facility and its impact on the production chain, the environment and the population.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjust deployments to reinforce the safeguarding of pipelines located in areas with the highest incidence of crime in terms of the illicit hydrocarbons market.

Our continued focus on the detection of illegal pipeline taps in 2025, together with the strict application of ground transportation protocols, enabled us to collect more information and develop more effective strategies to combat fuel theft, which in turn improved our ability to deploy ground patrol for the immediate identification and sealing of pipeline taps and avoid additional extraction of our hydrocarbon products.

The Strategic Safeguard Subdirectorate carries out surveillance and coordination activities within the scope of its operational functions to reduce the vulnerability of our infrastructure and contribute to the continuity of our value chain.

In 2024, surveillance and patrolling activities led to 12,414 alerts generated. All alerts in the pipeline transport systems were addressed, highlighting the dedication and commitment of the operational staff in maintaining a high level of performance.

In 2025, surveillance and coordination activities led us to address 7,976 out of 8,863 leak detection alerts generated, or 90.05% of such alerts, within approximately 60 minutes.

Our policy is to inform the Liabilities Unit at Petróleos Mexicanos when we become aware of information related to the illicit market in fuels that involves our personnel. The Liabilities Unit has the authority to investigate, undertake

administrative proceedings, impose penalties against employees or former employees in connection with this issue and file criminal complaints.

*Civil Actions* 

In the ordinary course of our business, we are a party to a number of lawsuits of various types. We evaluate the merit of each claim and assess the likely outcome, accruing a contingent liability when an unfavorable decision is probable and the amount is reasonably estimable. As of December 31, 2025 and 2024, we had accrued a reserve of Ps.13.4 billion and Ps.13.2 billion, respectively, for our contingent liabilities in connection with these lawsuits. Our material legal proceedings are described in Note 19 to our consolidated financial statements included in this report, and those descriptions are incorporated by reference under this Item 8.

*Trade Dispute*

On July 20, 2022, the United States of America and Canada each requested dispute settlement consultations with Mexico regarding Mexico's energy and oil policies. Such consultations argue that certain actions taken by Mexico are inconsistent with its commitments under the USMCA, particularly, those aimed at opening Mexico's electricity and oil markets to foreign investors. On December 12, 2022, Mexico presented a working plan aimed at resolving the dispute settlement consultations amicably. The notice of dispute under the USMCA regarding the energy sector policies and regulations remains in effect*,* and Mexico's Ministry of Economy is leading and coordinating the management of the consultation process.

**Dividends** 

Pursuant to the 2025 Petróleos Mexicanos Law, we were transformed from a productive state-owned company to a state-owned public company. Under the 2014 Petróleos Mexicanos Law, we and our subsidiary entities were subject to a dividend policy that required us to pay a state dividend to the Mexican Government on an annual basis. The 2025 Petróleos Mexicanos Law, which repealed and replaced the 2014 Petróleos Mexicanos Law, does not include a state dividend provision. Accordingly, we are no longer subject to the state dividend requirement, and we did not pay a state dividend in 2025. For more information, see "*Item 4—Information on the Company—Taxes, Duties and Other Payments to the Mexican Government—Fiscal Regime for PEMEX.*"

**Item 9.&nbsp;&nbsp;&nbsp;&nbsp;The Offer and Listing** 

Trading in the debt securities issued by Petróleos Mexicanos takes place primarily in the Over-The-Counter (OTC) market. All the debt securities issued by Petróleos Mexicanos that are registered pursuant to the U.S. Securities Act of 1933 (which we refer to as the Securities Act) are also listed on the Luxembourg Stock Exchange and traded on the Euro MTF market of the Luxembourg Stock Exchange.

**Item 10.&nbsp;&nbsp;&nbsp;&nbsp;Additional Information** 

**Memorandum and Articles of Association**

The Mexican Congress established Petróleos Mexicanos by a decree dated June 7, 1938, effective July 20, 1938. Petróleos Mexicanos does not have bylaws or articles of association.

interest. Our directors do not have the power to vote compensation to themselves or any other member of the board. Except in the case of the independent board members, our directors do not receive compensation for their services as members of the boards of directors of Petróleos Mexicanos and the subsidiary entities.

In 2021, we increased the size of this program to U.S.$125.0 billion. In 2023, we increased the size of this program to U.S.$130.0 billion and issued U.S.$2.0 billion of notes and bonds under it. Effective March 19, 2025, Pemex Exploration and Production, Pemex Industrial Transformation and Pemex Logistics were dissolved pursuant to the 2025 Petróleos Mexicanos Law, and all of their obligations, including under the guaranty arrangements described above, were assumed by Petróleos Mexicanos as their successor as a matter of Mexican law.

**Exchange Controls** 

Mexico has had a free market for foreign exchange since 1991, and the Mexican Government has allowed the peso to float freely against the U.S. dollar since December 1994. We have no control over or influence on this exchange rate policy. The Mexican Government has announced that it does not intend to change its floating exchange rate policy, but there is no guarantee that the Mexican Government will not change this policy.

Securities, the 2016 Securities, the 2018 Securities, the 2020 Securities and the 2022 Securities as the Registered Securities.

*Taxation Generally* 

The following summary contains a description of the principal Mexican and U.S. federal income tax consequences of the ownership and disposition of the Registered Securities, but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a decision to invest in, or dispose of, the Registered Securities.

This summary is based on the federal tax laws of Mexico and the United States in force on the date of this Form 20-F, including the provisions of the income tax treaty between the United States and Mexico together with related protocols (the "Tax Treaty") (which are subject to change), and does not describe any tax consequences arising under the laws of any state or municipality in Mexico, the United States or any other jurisdiction, or the laws of any taxing jurisdiction other than the federal laws of Mexico and the United States.

Mexico has also entered into, or is negotiating, tax treaties with various countries that may have effects on holders of Registered Securities. This report does not discuss the consequences (if any) of such treaties.

Each holder or beneficial owner of Registered Securities should consult its tax advisor as to the Mexican, United States or other tax consequences of the ownership and disposition of those securities, including the effect of any foreign, state or municipal tax laws, and the consequences of the application of any tax treaty to which Mexico is a party.

*Mexican Taxation* 

This summary of certain Mexican federal tax considerations refers only to holders of Registered Securities that are not residents of Mexico for Mexican tax purposes and that will not hold the Registered Securities or a beneficial interest therein through a permanent establishment for tax purposes (we refer to any such non-resident holder as a Foreign Holder). For purposes of Mexican taxation, an individual is a resident of Mexico if he/she has established his/her domicile in Mexico. When an individual also has a place of residence in another country, that individual will be considered a resident of Mexico for tax purposes, if such individual has his/her center of vital interest in Mexico. An individual would be deemed to have his/her center of vital interest in Mexico if, among other things: (a) more than 50% of his/her total income for the year were derived from Mexican sources, or (b) his/her principal center of professional activities were located in Mexico.

A legal entity is a resident of Mexico if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• it maintains the principal administration of its business in Mexico; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• it has established its effective management in Mexico.

A Mexican national is presumed to be a resident of Mexico unless such person can demonstrate the contrary. If a legal entity or individual has a permanent establishment in Mexico, such permanent establishment shall be required to pay taxes in Mexico on income attributable to such permanent establishment in accordance with Mexican federal tax law.

*Taxation of Interest*. Under the Mexican Income Tax Law and rules issued by the Ministry of Finance and Public Credit applicable to us, payments of interest (which are deemed to include any amounts paid in excess of the original issue price of the relevant securities), made by a Mexican issuer (including Petróleos Mexicanos) in respect of notes or bonds and other debt securities to a Foreign Holder will generally be subject to a Mexican withholding tax assessed at a rate of 4.9%, if the following requirements are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• notice relating to the offering of such notes or bonds is given to the CNBV as required under the Securities Market Law and evidence of such notice is timely filed with the Ministry of Finance and Public Credit;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• such notes or bonds are placed outside of Mexico through banks or brokerage houses in a country that is party to a treaty to avoid double taxation with Mexico; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the issuer duly complies with the information requirements established in the general rules issued by the Ministry of Finance and Public Credit for such purposes.

If the effective beneficiaries, directly or indirectly, individually or jointly with related parties, receive more than 5% of the interest paid on such notes or bonds and are holders, directly or indirectly, individually or jointly, with related parties of

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

more than 10% of the voting stock of the issuer or entities 20% or more of whose stock is owned directly or indirectly, individually or jointly, by parties related to the issuer, the withholding tax rate applicable to payment of interest on such notes or bonds may be significantly higher.

Payments of interest made by Petróleos Mexicanos, in respect of the Registered Securities to non-Mexican pension or retirement funds will be exempt from Mexican withholding taxes, provided that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• such fund is duly organized pursuant to the laws of its country of origin and is the effective beneficiary of the interest payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the income from such interest payment is exempt from income tax in its country of residence; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• such fund delivers certain information as per rules issued by the Ministry of Finance and Public Credit.

*Additional Amounts*. Petróleos Mexicanos, has agreed, subject to specified exceptions and limitations, to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pay Additional Amounts (as defined in the indenture dated as of September 18, 1997, as supplemented, between Petróleos Mexicanos and Deutsche Bank) to the holders of the 1997 Securities in respect of the Mexican withholding taxes mentioned above;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pay Additional Amounts (as defined in the indenture dated as of December 30, 2004, as supplemented, between Petróleos Mexicanos and Deutsche Bank) to the holders of the 2006 Securities and the 2008 Securities in respect of the Mexican withholding taxes described above; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pay Additional Amounts (as defined in the indenture dated as of January 27, 2009, as supplemented, between Petróleos Mexicanos and Deutsche Bank) to the holders of the 2009 Securities, the 2010 Securities, the 2011 Securities, the 2012 Securities, the 2013 Securities, the 2014 Securities, the 2016 Securities, the 2018 Securities, the 2020 Securities, the 2022 Securities and the 2023 Securities in respect of the Mexican withholding taxes described above.

If Petróleos Mexicanos pays Additional Amounts in respect of such Mexican withholding taxes, any refunds received with respect to such Additional Amounts will be for the account of Petróleos Mexicanos.

Holders or beneficial owners of the Registered Securities may be required to provide certain information or documentation necessary to enable Petróleos Mexicanos and the subsidiary entities to apply the appropriate Mexican withholding tax rate applicable to holders or beneficial owners of the Registered Securities. In the event that the specified information or documentation concerning such holder or beneficial owner, if requested, is not provided on a timely basis, the obligation of Petróleos Mexicanos and the subsidiary entities to pay Additional Amounts may be limited.

*Taxation of Dispositions*. Capital gains resulting from the sale or other disposition of the Registered Securities by a Foreign Holder will not be subject to Mexican income or withholding taxes.

*Other Mexican Tax Considerations*. Under the Mexican Income Tax Law, any discount received by a non-resident upon purchase of the notes or bonds from a Mexican resident or a non-resident with a permanent establishment in Mexico is deemed interest income, and therefore, subject to taxes in Mexico. Such interest income results from the difference between the face value (plus accrued interest not subject to withholding) and the purchase price of such notes or bonds.

*Transfer and Other Taxes*. There are no Mexican stamp, registration or similar taxes payable by a Foreign Holder in connection with the purchase, ownership or disposition of the Registered Securities. A Foreign Holder of the Registered Securities will not be liable for Mexican estate, succession, gift, inheritance or similar tax with respect to such securities.

*United States Taxation* 

This summary of certain U.S. federal income tax considerations deals principally with persons that hold the Registered Securities as capital assets and whose functional currency is the U.S. dollar. As used in this section "Taxation," the term "United States Holder" means a beneficial owner of a Registered Security that is an individual who is a citizen or resident of the United States, a U.S. domestic corporation or any other person that is subject to U.S. federal income taxation on a net income basis in respect of its investment in the Registered Securities.

This summary does not purport to be a comprehensive description of all the tax considerations that may be relevant to any particular investor, including tax considerations that arise from rules of general application or that are assumed to be

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

known to investors. This summary generally does not address the tax treatment of holders that may be subject to special tax rules, such as banks, insurance companies, tax-exempt organizations, dealers in securities or currencies, certain short-term holders of Registered Securities, traders in securities electing to mark-to-market, or persons that hedge their exposure in the Registered Securities or hold the Registered Securities as a position in a "straddle" for tax purposes or as part of a "synthetic security" or a "hedging" or "conversion" transaction or other integrated investment comprised of such Registered Securities and one or more other investments, nonresident aliens present in the United States for more than 182 days in a taxable year, U.S. expatriates, entities taxed as partnerships or the partners therein, or persons that have a "functional currency" other than the U.S. dollar.

In addition, this summary does not discuss the application of state, local, or foreign tax laws, U.S. federal estate or gift tax laws, the Medicare contribution tax on net investment income, the alternative minimum tax or special timing rules prescribed under section 451(b) of the U.S. Internal Revenue Code of 1986, as amended (the "Code"). United States Holders should consult their own tax advisers concerning the U.S. federal, state, local, foreign and other tax consequences of purchasing, owning, and disposing of a Registered Security in their particular circumstances.

*Taxation of Interest and Additional Amounts*. A United States Holder will treat the gross amount of stated interest and Additional Amounts (*i.e.*, without reduction for Mexican withholding taxes) as ordinary interest income in respect of the Registered Securities.

Subject to generally applicable limitations and conditions, Mexican interest withholding tax paid at the appropriate rate applicable to the United States Holder may be eligible for credit against such United States Holder's U.S. federal income tax liability. These generally applicable limitations and conditions include requirements adopted in December 2021 by the U.S. Internal Revenue Service ("IRS") and any Mexican tax will need to satisfy these requirements in order to be eligible to be a creditable tax for a United States Holder. In the case of a United States Holder that either (i) is eligible for, and properly elects, the benefits of the Tax Treaty, or (ii) consistently elects to apply a modified version of these rules under temporary guidance and complies with specific requirements set forth in such guidance, the Mexican tax on interest will generally be treated as meeting the requirements and therefore as a creditable tax. In the case of all other United States Holders, the application of these requirements to the Mexican tax on interest is uncertain and we have not determined whether these requirements have been met. If the Mexican interest tax is not a creditable tax for a United States Holder or the United States Holder does not elect to claim a foreign tax credit for any foreign income taxes paid or accrued in the same taxable year, the United States Holder may be able to deduct the Mexican tax in computing such United States Holder's taxable income for U.S. federal income tax purposes. Interest and Additional Amounts will constitute income from sources without the United States and, for United States 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 United States 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. United States Holders should consult their own tax advisors regarding the application of these rules to their particular situations.

*Original Issue Discount*. A Registered Security is issued with original issue discount ("OID") in an amount equal to the excess of its principal amount over its issue price. If the discount is equal to or more than a statutorily defined de minimis amount (the "Original Issue Discount Notes"), United States Holders generally will be subject to the special tax accounting rules for obligations issued with OID under the Code and certain regulations promulgated thereunder (the "OID Regulations"). The "issue price" of a series of Registered Securities is the first price at which a substantial amount of the Registered Securities is sold to the public (i.e., excluding sales of Registered Securities to underwriters, placement agents, wholesalers, or similar persons). United States Holders should be aware that, as described in greater detail below, they generally must include OID in ordinary gross income for U.S. federal income tax purposes as it accrues, generally in advance of the receipt of cash attributable to that income.

In general, each United States Holder of Original Issue Discount Notes, whether such holder uses the cash or the accrual method of tax accounting, will be required to include in ordinary gross income the sum of the "daily portions" of OID on the Original Issue Discount Note for all days during the taxable year that the United States Holder owns the Original Issue Discount Note. The daily portions of OID on an Original Issue Discount Note are determined by allocating to each day in any accrual period a ratable portion of the OID allocable to that accrual period. Accrual periods may be of any length and may vary in length over the term of an Original Issue Discount Note; provided that no accrual period is longer than one year and each scheduled payment of principal or interest occurs on either the final day or the first day of an accrual period. In the case of an initial holder, the amount of OID on an Original Issue Discount Note allocable to each

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

accrual period generally is determined by (a) multiplying the "adjusted issue price" (as defined below) of the Original Issue Discount Note at the beginning of the accrual period by the yield to maturity of such Original Issue Discount Note (appropriately adjusted to reflect the length of the accrual period) and (b) subtracting from that product the amount (if any) of qualified stated interest (as defined below) allocable to that accrual period. The yield to maturity of an Original Issue Discount Note is the discount rate that causes the present value of all payments on the Original Issue Discount Note as of its original issue date to equal the issue price of such Note. The "adjusted issue price" of an Original Issue Discount Note at the beginning of any accrual period will generally be the sum of its issue price (generally including accrued interest, if any) and the amount of OID allocable to all prior accrual periods, reduced by the amount of all payments other than payments of qualified stated interest (if any) made with respect to such Original Issue Discount Note in all prior accrual periods. The term "qualified stated interest" generally means stated interest that is unconditionally payable in cash or property (other than debt instruments of the issuer) at least annually during the entire term of a Note at a single fixed rate of interest or, subject to certain conditions, based on one or more interest indices. As a result of this "constant-yield" method of including OID in income, the amounts included in income by a United States Holder in respect of an Original Issue Discount Note generally are lesser in the early years and greater in the later years than the amounts that would be included on a straight-line basis. All payments on an Original Issue Discount Note (other than payments of qualified stated interest) will generally be viewed first as payments of previously-accrued OID (to the extent thereof), with payments attributed first to the earliest-accrued OID, and then as payments of principal.

A United States Holder generally may make an irrevocable election to include in its income its entire return on an Original Issue Discount Note (i.e., the excess of all remaining payments to be received on the Original Issue Discount Note, including payments of qualified stated interest, over the amount paid by such United States Holder for such Original Issue Discount Note) under the constant-yield method described above. For Original Issue Discount Notes purchased at a premium or bearing market discount in the hands of the United States Holder, a United States Holder making such election will also be deemed to have made the election (discussed below in "—*Premium and Market Discount*") to amortize premium or to accrue market discount in income currently on a constant-yield basis.

A United States Holder that purchases an Original Issue Discount Note at a cost less than its remaining redemption amount (as defined below) generally will be required to include in gross income the daily portions of OID, calculated as described above. However, if the United States Holder acquires an Original Issue Discount Note at a price greater than its adjusted issue price, such holder may reduce its periodic inclusions of OID income to reflect the premium paid over the adjusted issue price. The "remaining redemption amount" for an Original Issue Discount Note is the total of all future payments to be made on the Original Issue Discount Note other than payments of qualified stated interest.

*Premium and Market Discount*. A United States Holder of a Registered Security that purchases the Registered Security at a cost greater than its remaining redemption amount (as defined above) will be considered to have purchased the Registered Security at a premium and may elect to amortize such premium (as an offset to interest income), using a constant-yield method, over the remaining term of the Registered Security. Such election, once made, generally applies to all bonds held or subsequently acquired by the United States Holder during or after the first taxable year to which the election applies and may not be revoked without the consent of the IRS. A United States Holder that elects to amortize such premium must reduce its tax basis in a Registered Security by the amount of the premium amortized during its holding period. Original Issue Discount Notes purchased at a premium will not be subject to the OID rules described above. With respect to a United States Holder that does not elect to amortize bond premium, the amount of bond premium will be included in the United States Holder's tax basis when the Registered Security matures or is disposed of by the United States Holder. Therefore, a United States Holder that does not elect to amortize such premium and that holds the Registered Security to maturity generally will be required to treat the premium as capital loss when the Registered Security matures.

If a United States Holder of a Registered Security purchases the Registered Security at a price that is lower than its remaining redemption amount, or in the case of an Original Issue Discount Note, its adjusted issue price, by at least 0.25% of its remaining redemption amount multiplied by the number of remaining whole years to maturity, the Registered Security will be considered to have "market discount" in the hands of such United States Holder. In such case, gain realized by the United States Holder on the disposition of the Registered Security generally will be treated as ordinary income to the extent of the market discount that accrued on the Note while held by such United States Holder. In addition, the United States Holder could be required to defer the deduction of a portion of the interest paid on any indebtedness incurred or maintained to purchase or carry the Registered Security. In general terms, market discount on a Registered Security will be treated as accruing ratably over the term of such Registered Security, or, at the election of the holder, under a constant-yield method.

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

A United States Holder may elect to include market discount in income on a current basis as it accrues (on either a ratable or constant-yield basis), in lieu of treating a portion of any gain realized on a sale of a Registered Security as ordinary income. If a United States Holder elects to include market discount on a current basis, the interest deduction deferral rule described above will not apply. Any such election, if made, applies to all market discount bonds acquired by the taxpayer on or after the first day of the first taxable year to which such election applies and is revocable only with the consent of the IRS.

*Taxation of Dispositions*. Upon the sale, exchange or retirement of a Registered Security, a United States Holder will generally recognize a gain or loss equal to the difference between the amount realized (less any amounts attributable to accrued and unpaid interest not previously included in gross income, which will be taxable as ordinary income) and the holder's tax basis in such security. A United States Holder's basis in a Registered Security generally will equal the cost of the Registered Security to the United States Holder increased by any amounts included in income by the holder as OID and market discount and reduced by amortized premium and any payments on the Registered Security other than qualified stated interest. Except as discussed above with respect to market discount, gain or loss recognized by a United States Holder on the sale, redemption or other disposition of the Registered Securities generally will be long-term capital gain or loss if, at the time of disposition, the securities have been held for more than one year. Long-term capital gain realized by an individual United States Holder is generally taxed at lower rates than short-term capital gains or ordinary income. The deduction of capital losses is subject to limitations.

Where a Registered Security is issued at a discount from its principal amount, and the discount is less than the product of one-fourth of one percent (0.25 percent) of the principal amount of such Registered Security multiplied by the number of full years to maturity ("de minimis OID"), a United States Holder generally will include the de minimis OID in income as stated principal payments are made. The amount included in income with respect to each principal payment equals the product of the total amount of de minimis OID on the Registered Security and a fraction, the numerator of which is the amount of the principal payment made and the denominator is the stated principal amount of the Registered Security. Any amount of de minimis OID included in income by a United States Holder is treated as gain recognized on the retirement of the Registered Security.

Under the foreign tax credit requirements adopted by the IRS in regulations promulgated in December 2021, a United States Holder generally will not be entitled to a foreign tax credit for any Mexican tax imposed on the sale or other taxable disposition of the Registered Securities, except in the case of either (i) a United States Holder that is eligible for, and properly elects to claim, the benefits of the Tax Treaty or (ii) a United States Holder that consistently elects to apply a modified version of the U.S. foreign tax credit rules under temporary guidance, and complies with specific requirements set forth in such guidance. Additionally, capital gain or loss recognized by a United States Holder on the sale or other taxable disposition of the Registered Securities generally will be U.S. source gain or loss for U.S. foreign tax credit purposes (except to the extent that the United States Holder establishes the right to treat any gain as foreign source income under the Tax Treaty). Consequently, even if a Mexican tax qualifies as a creditable tax, a United States Holder who is not able to treat any gain (upon which the tax is imposed) as foreign source income under the Tax Treaty 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 tax is not a creditable tax, the tax would generally reduce the amount realized on the sale or other taxable disposition of the Registered Securities even if the United States 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. United States Holders should consult their own tax advisors regarding the application of the foreign tax credit rules to a sale or other taxable disposition of the Registered Securities and any Mexican tax imposed on such sale or other taxable disposition.

*Backup Withholding and Information Reporting*. Information returns may be filed with the IRS with respect to payments made to certain United States Holders of the Registered Securities. In addition, certain United States Holders may be subject to a backup withholding tax in respect of such payments, unless they (1) provide their accurate taxpayer identification numbers to the principal paying agent and certify that they are not subject to backup withholding or (2) otherwise establish an exemption from the backup withholding tax. Backup withholding is not an additional tax. Non-United States Holders may be required to comply with applicable certification procedures to establish that they are not United States Holders in order to avoid the application of such information reporting requirements and backup withholding tax. The amount of any backup withholding from a payment to a United States Holder or non-United States Holder will be allowed as a credit against the holder's U.S. federal income tax liability and may entitle the holder to a refund, provided that the required information is timely furnished to the IRS.

*Specified Foreign Financial Assets*. Certain United States Holders that own "specified foreign financial assets" with an aggregate value in excess of U.S.$50,000 on the last day of the taxable year, or U.S.$75,000 at any time during the taxable year, are generally required to file an information statement along with their tax returns, currently on IRS 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 (which would include the Registered Securities) 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 certain objective criteria. United States 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 be suspended, in whole or part. Prospective investors should consult their own tax advisors concerning the application of these rules to their investment in the Registered Securities, including the application of the rules to their particular circumstances.

**Item 11.&nbsp;&nbsp;&nbsp;&nbsp;Quantitative and Qualitative Disclosures About Market Risk** 

**QUALITATIVE DISCLOSURE** 

**Policies for Risk Management and the Use of Derivative Financial Instruments** 

We face market risk caused by the volatility of hydrocarbon prices, exchange rates and interest rates, credit risk associated with investments and financial derivatives, as well as liquidity risk. In order to monitor and manage these risks, we have approved general provisions relating to financial risk management, which are comprised of policies and guidelines that promote an integrated framework for risk management, regulate the use of Derivative Financial Instruments ("DFIs"), and guide the development of risk mitigation strategies.

This regulatory framework establishes that DFIs should be used only for the purpose of mitigating financial risk. The use of DFIs for any other purpose must be approved in accordance with our current internal regulation. We have a Financial Risk Working Group ("FRWG"), which is a specialized working group with decision-making authority over financial risk exposure, financial risk mitigation schemes, DFIs trading of Petróleos Mexicanos and, where applicable, the subsidiary companies.

Approved DFIs are mainly traded on the over-the-counter ("OTC") market; however, exchange traded instruments may also be used. In the case of PMI Trading, DFIs are traded on CME ClearPort.

The different types of DFIs that we trade are described below in the subsections corresponding to each risk type and as related to the applicable trading markets. See Note 18 to our consolidated financial statements included herein.

One of our policies is to minimize the impact that unfavorable changes in financial risk factors have on our financial results by promoting an adequate balance between incoming cash flows from operations and outgoing cash flows related to our liabilities.

As part of the regulatory framework for financial risk management, we have established the eligible counterparties with which we may trade DFIs and other financial instruments.

In addition, certain PMI Subsidiaries have implemented a regulatory framework for risk management with respect to its activities, which consists of policies, guidelines and procedures to manage the market risk associated with its commodity trading activities in accordance with industry best practices, such as: (1) the use of DFIs for financial risk mitigation purposes; (2) the segregation of duties; (3) valuation and monitoring mechanisms, such as the generation of a daily portfolio risk report, value at risk ("VaR") computation; and (4) VaR limits, at a business unit level and the implementation of stop loss mechanisms.

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

Given that our outstanding DFIs have been entered into for risk mitigation purposes, particularly with economic hedging purposes, there is no need to establish and monitor market risk limits.

For those portfolios with an open market risk exposure, our financial risk management regulatory framework establishes the implementation and monitoring of market risk metrics and limits (such as VaR, among others).

We have also established credit guidelines for DFIs that we offer to our domestic customers, which include the use of guarantees and credit lines. For exchange traded DFIs, we trade under the margin requirements of the corresponding exchange market, and therefore, do not have internal policies for these DFIs.

Most of the DFIs held with financial counterparties do not require collateral exchange clauses. Notwithstanding, our regulatory framework promotes credit risk mitigation strategies, such as collateral exchange.

We do not have an independent third party to verify compliance with these internal standards; however, we have internal control procedures that certify compliance with existing policies and guidelines.

**Description about Valuation Techniques** 

*Fair Value of DFIs* 

We periodically evaluate our exposure to international hydrocarbon prices, interest rates and foreign currencies and use derivative instruments as a mitigation mechanism when potential sources of market risk are identified.

We monitor the fair value of our DFI portfolio on a periodic basis. The fair value represents the price at which one party would assume the rights and obligations of the other and is calculated for DFIs through models commonly used in the international financial markets, based on inputs obtained from major market information systems and price providers. Therefore, we do not have an independent third party to value our DFIs.

We calculate the fair value of our DFIs through the tools developed by our market information providers, and through valuation models implemented in software packages used to integrate all of our business areas and accounting, such as System Applications Products ("SAP").

Our DFI portfolio is composed primarily of swaps, for which fair value, or Mark-to-Market ("MtM"), is estimated by projecting future cash flows and discounting them with the corresponding market discount factor.

For the projection of variable flows, the prices of future contracts of each of the references corresponding to these trades are used.

For currency and interest rate options, this is done through the Black and Scholes model, which uses as inputs the prices of the underlying futures, the reference prices agreed in the contracted instruments, the market risk-free rates and the implied volatilities of the instruments traded in the markets. In the case of crude oil options, the Levy Model for Asian options is used, which is based on the Black and Scholes Model, with the difference that this model weights the prices of the futures involved during the hedging period and contemplates a volatility adjustment, based on the terms of the corresponding futures.

According to IFRS 13 "Fair Value Measurement", the MtM value of DFIs must reflect the creditworthiness of the parties. Consequently, the fair value of a DFI takes into account the risk that either party may default on its obligation, considering the counterparties' probability of default. Due to the above, we apply the credit value adjustment ("CVA") method to calculate the fair value of our DFIs.

Given that our hedges are cash flow hedges, their effectiveness is preserved regardless of variations in the underlying assets or reference variables since, over time, asset flows are offset by liabilities flows. Therefore, and in addition to the fact that these hedges are established for accounting purposes as trading instruments, it is not considered necessary to measure the hedges' effectiveness or to monitor them.

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

*Fair value hierarchy* 

We value our DFIs using standard methodologies commonly applied in the financial markets. The fair-value assumptions and inputs utilized are classified in the three levels of the fair value hierarchy for market participant assumptions, as described below.

The fair values determined by Level 1 inputs utilize quoted prices in financial markets for identical assets or liabilities. Fair values determined by Level 2 inputs are based on quoted prices for similar assets or liabilities in financial markets, and inputs other than quoted prices that are observed for assets or liabilities. Fair values determined by Level 3 inputs are unobservable inputs for the assets or liabilities, and include situations where there is little, if any, market activity for the assets or liabilities. Management uses appropriate valuation techniques based on the available inputs to measure the fair values of our applicable assets and liabilities.

When available, we measure fair value using Level 1 inputs, because they generally provide the most reliable evidence of fair value.

The fair value assumptions and inputs utilized in the valuation of our DFIs' fair value, fall under Level 2 of the fair value hierarchy.

**Liquidity Sources** 

*Liquidity Risk* 

Our main internal source of liquidity comes from our operations. Additionally, through our debt planning and the purchase and sale of U.S. dollars, we currently preserve a cash balance at a level of liquidity in domestic currency and U.S. dollars that is considered adequate to cover our investment and operating expenses, as well as other payment obligations, such as those related to DFIs.

In addition, as of December 31, 2025, Petróleos Mexicanos has acquired a committed U.S. dollar revolving credit line in order to mitigate liquidity risk. The credit line provides access to U.S. $3,508 million with an expiration date in November 2026. As of December 31, 2025, this credit line is fully available. For more information, see Note 15 to our consolidated financial statements included herein.

During 2025, we entered into FX Forwards MXN/ U.S.$ in order to preserve an adequate level of liquidity in U.S. dollars. As of December 31, 2025, none of these DFIs were outstanding.

Additionally, as a liquidity risk mitigation strategy, during 2025 we carried out two voluntary synthetic recouponings, which involved the restructuring of five UDI/MXN DFIs. Additionally, in the fourth quarter of 2025, we entered into four DFI structures, three of which are composed of two U.S.$/MXN cross currency swaps and five MXN/U.S.$ prepaid forwards each, while the other structure is composed of a U.S.$/MXN cross currency swap and two MXN/U.S.$ exchange rate options. Furthermore, the restructuring of two MXN/U.S.$ prepaid swaps was carried out.

For the same purpose, during 2024, we entered into one MXN/U.S.$ prepaid swap and carried out two voluntary synthetic recouponings, which involved the restructuring of five UDI/MXN DFIs. Additionally, during 2023, we entered into two MXN/USD prepaid swaps, one of which matured during the second quarter of 2025 and also carried out a voluntary synthetic recouponing which involved the restructuring of five UDI/MXN DFIs and six EUR/USD cross currency capped swaps.

Finally, the investment strategies of our portfolios are structured by selecting time horizons that consider each currency's cash flow requirements in order to preserve liquidity.

PMI Subsidiaries mitigate their liquidity risk through several mechanisms, the most important of which is its centralized treasury, which provides access to two syndicated credit facilities for up to U.S. $500 million and U.S.$1,500 million, respectively, and cash surplus capacity in the custody of the centralized structure. In addition, certain PMI Subsidiaries have access to bilateral credit lines from financial institutions for up to U.S. $200 million.

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

These companies monitor their cash flow on a daily basis and protect their creditworthiness in the financial markets. Liquidity risk is mitigated by monitoring certain financial ratios as set forth in the policies approved by each company's board of directors.

**Changes in Exposure to Main Risks** 

*Market Risk* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(i)Interest Rate Risk***

We are exposed to fluctuations in floating interest rate liabilities. We are exposed to U.S. dollar Secured Overnight Financing Rate (SOFR), to TIIE Mexican peso and TIIE funding rate. As of December 31, 2025, approximately 20.8% of the total net debt outstanding (including DFIs) consisted of floating rate debt.

Moreover, we invest in pesos and U.S. dollars in compliance with applicable internal regulations, through portfolios that have different purposes that seek an adequate return subject to risk parameters that reduce the probability of capital losses. The objective of the investments made through these portfolios is to meet our obligations payable in pesos and U.S. dollars.

The investments made through our portfolios are exposed to domestic and international interest rate risk and credit spread risk derived from government and corporate securities, and inflation risk arising from the relationship between Unidades de Inversión ("UDIs") and pesos. However, these risks are mitigated by established limits on exposure to market risk.

*Interest Rate Swaps* 

Occasionally, for strategic reasons or in order to offset the expected inflows and outflows, we have entered into interest rate swaps and options. Through the swap agreements, we acquire the obligation to make payments based on a fixed or floating interest rate in exchange for receiving payments referenced to a floating or fixed interest rate according to what is assessed as convenient. On the other hand, under the option agreements, we acquire protection against potential increases in the floating interest rates of some of our liabilities.

During 2024, we entered into nine interest rate swaps for an accumulated notional amount of U.S.$900 million, through which the fixed coupons associated with a U.S.$1,988 million debt issue maturing in 2028 were converted into floating coupons referenced to SOFR floating interest rates, in order to reduce the financial cost.

During 2025, as a result of PEMEX's liability management, an unwind of an interest rate hedging DFI associated with the repurchased bonds was executed, for a notional amount of U.S.$100 million.

As of December 31, 2025, we were a party to eight interest rate swap agreements denominated in U.S. dollars for an aggregate notional amount of U.S.$800 million at a weighted average fixed interest rate of 5.35% and a weighted average term of 2.1 years.

Similarly, in order to eliminate the volatility associated with variable interest rates of long-term financing operations, PMI NASA could also execute interest rate swap agreements denominated in U.S. dollars.

As of December 31, 2025, there was no ongoing interest rate DFI of PMI NASA.

*Reference rates transition* 

As a result of the decision made by the Financial Stability Board (FSB), the Interbank Offered Rates (IBORs) were replaced by alternative reference rates, based on risk-free rates obtained from market operations. Therefore, we have carried out the necessary actions to amend the contracts that were referenced to IBOR benchmark rates in accordance with the applicable regulations.

In line with market practice, PMI Trading's credit agreements include the new language to use the Secured Overnight Funding Rate (SOFR) as their reference rate.

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

Banco de Mexico (the Mexican Central Bank) announced that the 28-day TIIE ceased to be a reference for new contracts as of January 1, 2025. Similarly, the 91-day and 182-day TIIE ceased to be reference rates for new contracts as of January 1, 2024. In response, Petróleos Mexicanos carried out the actions it deemed pertinent and necessary to modify contracts referenced to TIIE rates in line with the modifications announced by Banco de Mexico.

In the event that TIIE ceases to be published, the financial instruments portfolio referenced to these floating rates is composed of debt instruments and DFIs as shown below:

---

|:---|:---|:---|
| | **Reference Rate** | **Notional Amount**<br>**As of December 31, 2025**<br>**(in millions of pesos)**<sup>(1)</sup> |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(1)</sup> Notional amounts with maturity after December 31, 2025.

Our portfolio also consists of additional debt instruments and DFIs referenced at fixed and float rates, which are not listed in the table above since these instruments will not be impacted by this change.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(ii)Exchange Rate Risk***

Most of our revenues are denominated in U.S. dollars, a significant amount of which is derived from exports of crude oil and petroleum products, which are priced and payable in U.S. dollars. Additionally, our revenues from domestic sales of gasoline and diesel net of IEPS Tax, tax duties, incentives, and other related taxes, as well as domestic sales of natural gas and its byproducts, LPG and petrochemicals, are referenced to international U.S. dollar-denominated prices.

Our expenses related to hydrocarbon duties are calculated based on international U.S. dollar-denominated prices and the cost of hydrocarbon imports that we acquire for resale in Mexico or use in our facilities are indexed to international U.S. dollar-denominated prices. By contrast, we determine the annual amount to be allocated to our capital expenditure and operating expenses as a fixed amount in pesos.

As a result of this cash flow structure, the depreciation of the peso against the U.S. dollar increases our financial balance. The appreciation of the peso relative to the U.S. dollar has the opposite effect. We manage this risk without hedging instruments because the impact of exchange rate fluctuations between the U.S. dollar and the peso on our revenues is partially offset by its impact on our obligations.

<u>Cross-Currency Swaps</u>

We prioritize debt issuances denominated in U.S. dollars; nonetheless, this is not always achievable, hence non-U.S. dollar-denominated debt issued in international currencies is hedged through DFIs to mitigate its exchange rate exposure, either by swapping it into U.S. dollars or through other derivative structures. The rest of the debt is denominated in pesos or in UDIs, and for the debt denominated in UDIs, it has been converted into pesos through DFIs in order to eliminate the inflationary risk exposure.

As a consequence of the above, our debt issued in international currencies other than U.S. dollars has exchange rate risk mitigation strategies. We have selected strategies that further seek to reduce our cost of funding by leaving, in some cases, part of this exchange rate exposure unhedged when assessed as appropriate.

The underlying currencies of our DFIs that mitigate the exchange rate risk are the euro and the Japanese yen against the U.S. dollar and UDIs against the peso.

As of December 31, 2025, and 2024, we did not enter into any DFIs to mitigate the exchange rate risk, as no debt in currencies other than U.S. dollars or pesos was issued.

Nevertheless, during 2025, as a result of Pemex's liability management, eighteen total unwinds and three partial unwinds of exchange rate risk hedging DFIs associated with the repurchased bonds were carried out for a cumulative notional amount of €3,211.8 million.

We recorded a total foreign exchange gain (loss) of Ps. 195,182.4 million, Ps. (304,452.2) million and Ps. 238,079.0 million, for the years ended December 31, 2025, 2024 and 2023, respectively. These amounts include the unrealized foreign exchange gain (loss) associated with debt of Ps. 178,825.7 million, Ps. (261,416.7) million and Ps. 208,865.3 million for the years ended December 31, 2025, 2024 and 2023, respectively. Unrealized foreign exchange gains and losses do not impact our cash flows.

The appreciation of the peso during 2025 caused a total net foreign exchange gain because a significant portion of our debt, 90.95% (principal only) as of December 31, 2025 is denominated in a currency other than the Mexican peso. Due to the cash flow structure described above, the depreciation of the peso relative to the U.S. dollar does not affect our ability to meet U.S. dollar-denominated financial obligations and improves our ability to meet peso-denominated financial obligations. On the other hand, the appreciation of the peso relative to the U.S. dollar may increase our peso-denominated debt service costs on a U.S. dollar basis.

Certain of the PMI Subsidiaries face market risks generated by fluctuations in foreign exchange rates. In order to mitigate these risks, the boards of directors of several of these companies have authorized a policy which stipulates that financial assets must be denominated in our functional currency, unless the company owes a duty or expected payment in a currency other than our functional one.

Finally, a significant amount of PMI Trading's income and expenses, including the cost of sales and related sales costs, is derived from the trade of refined products, petrochemicals and gas liquids to our subsidiaries and third parties, whose prices are determined and are payable in U.S. dollars. PMI Trading's exposure to foreign currency risk results primarily from the need to fund tax payments denominated in domestic currency, as well as from certain related sales costs denominated in domestic currency.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(iii)Hydrocarbon Price Risk***

We periodically assess our revenues and expenditures structure in order to identify the main market risk factors that our cash flows are exposed to in connection with international hydrocarbon prices. Based on this assessment, we monitor our exposure to the most significant risk factors and quantify their impact on our financial balance.

Our exports and domestic sales are directly or indirectly related to international hydrocarbon prices. Therefore, we are exposed to fluctuations in these prices. In terms of crude oil and natural gas, part of this risk is transferred to the Mexican Government under our current fiscal regime.

Our exposure to hydrocarbon prices is partly mitigated by natural hedges between our inflows and outflows.

Additionally, we continuously evaluate the implementation of risk mitigation strategies, including those involving the use of DFIs, taking into consideration their operative and budgetary feasibility.

<u>Commodity Derivatives</u>

In 2017, the Board of Directors of Petróleos Mexicanos approved the establishment of our Programa Anual de Coberturas Petroleras (Annual Oil Hedging Program). Since then, we have implemented hedging strategies to protect our cash flows from falls in the Mexican crude oil basket price from the level that we assess as adequate, considering the cost-protection ratio.

During the second half of 2023 and the first quarter of 2024, we entered into the crude oil hedge for the fiscal year 2024, pursuant to which we hedged 168 thousand barrels per day on average for the period between January 2024 and December 2024, for U.S.$118.5 million.

During the fourth quarter of 2024 and the first quarter of 2025, we entered into the crude oil hedge for the fiscal year 2025, pursuant to which we hedged 455 thousand barrels per day on average for the period between January 2025 and December 2025, for U.S.$195.4 million.

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

As of December 31, 2025, we do not have any active hydrocarbon price risk hedging DFIs related to the oil hedge.

Additionally, our cash flows are exposed to crack spread movements as these determine the refining margin.

During 2025, we implemented a hedging strategy to partially protect our cash flows exposed to diesel crack spread against drops below a level higher than the one established in the Federal Revenue Law for the fiscal year 2025. This is a zero-cost hedging strategy, carried out through swaps which hedged 4,110,000 barrels for the period between July 2025 and November 2025.

Additionally, during the first semester of 2025 we implemented a hedging strategy to partially protect our cash flows exposed to gasoline crack spread against drops below a level higher than the one established in the Federal Revenue Law for the fiscal year 2025. This is a zero-cost hedging strategy, carried out through swaps which hedged 5,310,000 barrels for the period between March 2025 and August 2025.

As of December 31, 2025, we do not have any active hydrocarbon commodity price risk hedging DFIs related to the diesel or gasoline crack spread.

In addition to supplying natural gas, we can offer DFIs to our domestic customers in order to provide them with support to mitigate the risk associated with the volatility of natural gas prices.

PMI Trading faces market risk generated by the terms of the purchase and sale of refined products and natural gas liquids, as well as the volatility of oil prices. Accordingly, it frequently enters into DFIs in order to mitigate this risk, thereby reducing the volatility of its financial results.

In accordance with the risk management regulatory framework that PMI Trading has implemented, VaR and the change in profit and loss by portfolio are calculated daily and compared to the maximum applicable limits in order to implement risk mitigation mechanisms as necessary.

**Counterparty or Credit Risk** 

When the fair value of a DFI is favorable to us, we face the risk that the counterparty will not be able to meet its obligations. We monitor our counterparties' creditworthiness and calculate the credit risk exposure for our DFIs. As a risk mitigation strategy, we only enter into DFIs with major financial institutions with a minimum credit rating of BBB-. These ratings are issued and revised periodically by risk rating agencies. Furthermore, we seek to maintain a diversified portfolio of counterparties.

In order to estimate our credit risk exposure to each financial counterparty, the potential future exposure is calculated by projecting the risk factors used in the valuation of each DFI in order to estimate the MtM value for different periods, taking into account any credit risk mitigation provisions.

Moreover, we have entered into various long-term cross-currency swap agreements using the following as credit risk mitigants: 1) recouponing clauses (pursuant to which when the MtM exceeds the threshold specified in the confirmation, the MtM is adjusted to zero and notional amount is also adjusted), thereby limiting the PEMEX's exposure to its counterparties referenced to a specific threshold amount, as well as the counterparties' exposure to PEMEX; 2) set-off clauses (under which, in the event of a default by either party, the other party has the option to settle the MtM owed to it through the delivery of bonds issued by the defaulting party).

During 2025, three DFIs structures were entered into with the set-off clause. In addition, recouponing clauses were not triggered in any DFI, and no new DFIs with this feature were entered into.

According to IFRS 13 "Fair Value Measurement," the fair value or MtM value of DFIs must reflect the creditworthiness of the parties. Consequently, the fair value of a DFI takes into account the risk that either party may default on its obligation. Due to the above, we apply the credit value adjustment ("CVA") method to calculate the fair value of our DFIs.

For each DFI, the CVA is calculated by determining the difference between the MtM and the estimated MtM adjusted for credit risk. In determining the credit risk, the CVA method takes into account the current market perception about the credit risk of both counterparties, using the following inputs: (a) the MtM projection for each payment date based on

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

forward yield curves; (b) the implied default probability obtained from both our and the counterparty's credit default swaps, at each payment date; and (c) the default recovery rates of each counterparty.

Furthermore, by means of its credit guidelines for DFI operations, we significantly reduce our credit risk exposure related to the DFIs.

In order to qualify for these DFIs, our customers must be party to a current natural gas supply contract and sign a domestic master derivative agreement.

Additionally, according to the credit guidelines, DFIs with these customers must be initially secured by cash deposits, letters of credit or other collateral provisions, as required. The credit guidelines indicate that we may offer DFIs with an exemption from collateral requirements up to a certain amount, through a credit line approved by the credit committee, based on an internal financial and credit assessment. Moreover, if the credit line is insufficient to cover each client's exposure, the client is obligated to deposit collateral.

In accordance with these guidelines, in the event that a client does not meet its payment obligations, DFIs related to this client would be terminated, rights to any available collateral would be exercised and, if the collateral were insufficient to cover the fair value, or in the absence of collateral, natural gas supply would be suspended until the payment is made.

As of December 31, 2025, we had no DFIs.

PMI Trading's credit risk associated with DFI transactions is mitigated by the use of futures and standardized instruments that are cleared through CME-ClearPort.

**Accounting Standards Applied and the Impact on Results** 

We enter into derivatives transactions with the sole purpose of hedging financial risks related to our operations, firm commitments, planned transactions and assets and liabilities recorded on our statement of financial position. Nonetheless, some of these transactions do not qualify for hedge accounting treatment because they do not meet the requirements of the accounting standards for designation as hedges. They are therefore recorded in the financial statements as instruments entered into for trading purposes, despite the fact that their cash flows are offset by the cash flows of the positions (assets or liabilities) to which they relate. As a result, the changes in their fair value are recognized in the "Derivative financial instruments income (cost), net" line item in the consolidated statement of comprehensive income.

As of December 31, 2025, and 2024, the net fair value of our DFIs, including both DFIs that have not reached maturity and those that have reached maturity but have not been settled, recognized in our consolidated statement of financial position, was Ps. (63,571.9) million and Ps. (99,768.5) million, respectively. As of December 31, 2025, and 2024, we did not have any DFIs designated as hedges for accounting purposes. See Note 18 to our consolidated financial statements included herein.

All of our DFIs are treated, for accounting purposes, as instruments entered into for trading purposes, therefore any change in their fair value, caused by any act or event, impacts directly in the "Derivative financial instruments income (cost), net" line item in our consolidated statement of comprehensive income.

For the years ended December 31, 2025, 2024 and 2023, we recognized a net gain (loss) of Ps. 21,587.9 million, Ps. (27,594.2) million, and Ps. 672.2 million respectively, in the "Derivative financial instruments income (cost), net" line item with respect to DFIs treated as instruments entered into for trading purposes (the gain as of December 31, 2023, includes the gain generated by the embedded derivative and the loss as of December 31, 2024, includes the loss from the cancellation of the embedded derivative).

**Embedded derivatives**

In accordance with established accounting policies, we have analyzed the different contracts (financial and non-financial) that we have entered into and have determined that according to the terms thereof none of these agreements meet the criteria to be classified as embedded derivatives. Accordingly, as of December 31, 2025, and 2024, we did not recognize any embedded derivatives (foreign currency or index) in our financial and non-financial contracts.

As of December 31, 2023, we recognized a favorable implicit forward for Ps. 194.2 million contained in an FX Single Cross Currency Swap contract, which expired in February 2024.

**QUANTITATIVE DISCLOSURE** 

**Fair Value** 

The following tables show our cash flow maturities, as well as the fair value of our debt and DFI portfolios as of December 31, 2025. It should be noted that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For debt obligations, these tables present principal cash flow and the weighted average interest rates for fixed rate debt.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For interest rate swaps, interest rate options, cross-currency swaps and currency options, these tables present notional amounts and weighted average interest rates by expected (contractual) maturity dates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Weighted average variable rates are based on implied forward rates obtained from the interbank market yield curve at the reporting date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For crude oil and crack spread, volumes are presented in millions of barrels, and fixed average and strike prices are presented in U.S. dollars per barrel.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• DFIs' fair value includes CVA and is calculated based on market quotes obtained from market sources such as Bloomberg, Proveedor Integral de Precios, S.A. de C.V. ("PIP"), among others.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For PMI Trading, the prices used in commercial transactions and DFIs are published by reputable sources that are widely used in international markets, such as CME-NYMEX, Platts and Argus, among others.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Fair value is calculated internally, either by discounting cash flows with the corresponding zero-coupon yield curve in the original currency, or through other standard methodologies commonly used in financial markets for specific instruments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For all instruments, the tables are based on the contract terms in order to determine the future cash flows that are categorized by expected maturity dates.

(4)Swaps registered in CME ClearPort are included in these figures.

(5)The balance of these instruments is presented as part of cash and cash equivalents as they are considered fully liquid.

**Sensitivity Analysis** 

We have entered into DFIs to mitigate the market risk for specific flows or predetermined volumes associated with our operations. Our DFIs have the same characteristics (e.g., underlying assets, payment dates, amounts or volumes) as the hedged position, but with the opposite exposure to the market risk factors. As a result of these mitigation strategies, we have a minor sensitivity to the hedged market risk factors. See Note 18 to our consolidated financial statements included herein.

Given that our hedges are cash flow hedges, their effectiveness is preserved regardless of variations in the underlying assets or reference variables since, over time, asset flows are offset by liabilities flows. Therefore, and in addition to the fact that these hedges are established for accounting purposes as trading instruments, it is not considered necessary to measure the hedges' effectiveness or to monitor them.

The natural gas DFIs that we have offered to our domestic customers have been reported as transactions with trading purposes. However, such operations were fully compensated by the operations entered into with financial counterparties, maintaining a negligible or even null exposure to market risk (due to this back-to-back mechanism). As of December 31, 2025, we did not have any such DFIs to report. As such, it is not necessary to conduct either a sensitivity analysis or to measure or monitor the hedge effectiveness.

Other DFIs seek to hedge the changes in the price of the commercialized products, such that the DFIs' underlying assets have correlations with the prices of the products involved in commercialization. PMI Trading estimates the VaR of these DFIs. Notably, DFIs of PMI Trading (all of them related to petroleum derivatives), are classified under cash and cash equivalents for accounting purposes due to their liquidity.

**Item 15.&nbsp;&nbsp;&nbsp;&nbsp;Controls and Procedures** 

**(a) Disclosure Controls and Procedures**

We carried out an evaluation under the supervision and with the participation of our management, including our *Director General* (Chief Executive Officer or CEO) and our *Director Corporativo de Finanzas* (Chief Financial Officer or CFO), of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of December 31, 2025. 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 controls and procedures. Accordingly, effective disclosure controls and procedures can provide only reasonable assurance of achieving their control objectives.

Based on our evaluation, and due to the material weakness in internal control over financial reporting as described below, our CEO and CFO concluded that our disclosure controls and procedures as of December 31, 2025 were not effective to provide reasonable assurance that information required to be disclosed in the reports we file and submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosures.

**(b) Management's Annual Report on Internal Control over Financial Reporting**

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act). Our 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 IFRS. Our internal control over financial reporting includes those policies and procedures that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Provide reasonable assurance that transactions are recorded as necessary to allow preparation of financial statements in accordance with IFRS and with Item 18 of Form 20-F, and that our receipts and expenditures are being made only in accordance with authorizations of management and directors of the relevant entity; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. 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 consolidated 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 for future periods are subject to the risk that the related controls may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate.

Our management, with participation of the CEO and CFO, under the oversight of our Board of Directors, evaluated the effectiveness of our internal control over financial reporting as of December 31, 2025, using the framework in Internal Control - Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that evaluation, management concluded that our internal control over financial reporting was not effective as of December 31, 2025, due to the material weakness in internal control over financial reporting described below.

Our management concluded that, as of December 31, 2025, 2024 and 2023, there was a material weakness in our internal control over financial reporting related to our authorization process for manual journal entries in our financial recording systems, including SAP. Specifically, our control environment was not designed with the appropriate precision to segregate duties related to creating and recording manual journal entries in our financial recording systems for the years ended December 31, 2025, 2024 and 2023.

As of the date of this annual report, we have not identified any errors or misstatements resulting from the control deficiencies described above. The configuration of our billing and payment system does not allow the execution of processes originating from manual journal entries, and we carry out reconciliation processes for the main processes

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

involving manual journal entries. However, there is a risk that some manual journal entries have not been subjected to the approval or review process that all other records undergo, and the financial information in our system could be inaccurate. Ultimately, such control deficiencies create a reasonable possibility that a material misstatement to the consolidated financial statements for the years ended December 31, 2025, 2024 and 2023, would not be prevented or detected on a timely basis.

In response to the material weakness described above, during 2025, our management reassessed and overhauled our prior remediation methodology and adopted a revised remediation plan designed to more precisely identify and address manual journal entries subject to risk. As part of this reassessment, our management retooled the methodology used to identify and categorize manual journal entries in Petróleos Mexicanos and its subsidiary companies, including by analyzing and categorizing such entries by process and responsible area.

As part of the revised remediation plan, our management performed procedures to evaluate whether manual journal entries identified as subject to risk were supported by adequate controls. These procedures consisted of targeted process walkthroughs, prioritized based on concentration and recurrence and focused on areas of higher operational exposure. Based on that work, our management identified two categories of manual journal entries: (i) entries for which existing controls were determined to be adequate and (ii) entries for which additional controls are required. Based on the work performed to date, our management has determined that the total number of journal entries recorded corresponding to manual journal entries subject to risk is not significant, and that the majority of such entries are already subject to effective controls.

For manual journal entries in the second category, the revised remediation plan contemplates the implementation of automated controls, including the "Park and Post" functionality in SAP, and, where automation is not feasible due to the nature of the underlying process, compensating controls designed to provide appropriate segregation of duties and supervisory review. We expect these measures to be implemented initially at Petróleos Mexicanos and thereafter extended to the subsidiary companies.

We believe that we have made progress in addressing this material weakness through the reassessment and redesign of our remediation approach, the more precise identification and categorization of manual journal entries subject to risk and the design of the remediation measures described above. However, as of December 31, 2025, this material weakness had not been fully remediated, and we continue to take actions to implement the revised remediation plan during 2026.

**(d) Changes in Internal Control over Financial Reporting**

There has been no change in our internal control over financial reporting during 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

**Item 16A.&nbsp;&nbsp;&nbsp;&nbsp;Audit Committee Financial Experts** 

Mr. Juan José Paullada Figueroa and Mrs. María del Rosío Vargas Suárez, members of the Audit Committee of Petróleos Mexicanos as of December 31, 2025, qualify as "audit committee financial experts" within the meaning of this Item 16A, and are independent, as defined in Rule 10A-3 under the Exchange Act. For the Audit Committee that assumed its functions pursuant to the 2025 Petróleos Mexicanos Law, Mr. Juan José Paullada Figueroa qualifies as an "audit committee financial expert."

**Item 16B.&nbsp;&nbsp;&nbsp;&nbsp;Code of Ethics** 

In accordance with the Petróleos Mexicanos Law, in November 2016, we issued the Code of Ethics for Petróleos Mexicanos, its productive subsidiary entities and affiliates, a code of ethics as defined in Item 16B of Form 20-F under the Exchange Act. The Code of Ethics for Petróleos Mexicanos remains in force in its current form and has not been modified as a result of the enactment of the 2025 Petróleos Mexicanos Law.

On November 26, 2019, the Board of Directors of Petróleos Mexicanos approved and issued an updated Code of Ethics. An updated Code of Ethics was published in the Official Gazette of the Federation on December 24, 2019.

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

Our Code of Ethics applies to the members of the Board of Directors of Petróleos Mexicanos and all our employees, including our General Director (Chief Executive Officer), Chief Financial Officer, Chief Accounting Officer and all other employees performing similar functions, as well as other individuals and companies whose actions may affect our reputation. The Code of Ethics is a key component of our ethics and integrity program, aimed at eradicating corruption. The Code of Ethics comprises the principles and values that govern the actions of officers and personnel in an environment of respect, non-discrimination, honesty, loyalty, responsibility, legality, impartiality, integrity, inclusivity and human rights, among others, that we expect will help us achieve our goals and which should be reflected in the daily behavior of our employees.

Our Code of Ethics is available on our website at http://www.pemex.com. Waivers cannot be granted to the provisions of this Code. Any amendment to the provisions of the Code of Ethics, will be disclosed on our website at the same address.

On December 7, 2016, our Ethics Committee was formed to monitor the implementation and enforcement of the Code of Ethics. See "*Item 4—Information on the Company—Business Overview—PEMEX Corporate Matters—Ethics Committee*" for more information.

In addition, on November 11, 2019 the new Code of Conduct for Petróleos Mexicanos, its productive subsidiary entities and, where applicable, affiliated companies, was published into the Official Gazette of the Federation. This Code of Conduct delineates behaviors expected of and banned for our employees, in accordance with the values established in the Code of Ethics approved by the Board of Directors of Petróleos Mexicanos and contemplates data protection and transparency related matters.

On September 11, 2017, the Anti-corruption Policies and Guidelines for Petróleos Mexicanos, its productive subsidiary entities and, where applicable, affiliated companies and the Policies and Guidelines to carry out Due Diligence in Petróleos Mexicanos, its productive subsidiary entities and, where applicable, affiliated companies, in Ethics and Corporate Integrity Matters became effective. These Policies and Guidelines were updated and published in the Official Gazette of the Federation on May 17, 2023. The purpose of these regulations is to take action to prevent acts of corruption, as well as provide means for executives and employees to identify, manage, mitigate and confront our own risks as well as third-party risks that may affect the attainment of our objectives with respect to corruption, corporate integrity or our involvement in illicit acts of any kind.

Additionally, we have an ethics tip line and a telephone number available on our website, as a mechanism to provide advice to address questions on ethics and integrity issues within PEMEX and to facilitate receipt of complaints about possible violations to our Code of Ethics or of our Code of Conduct. The information received is channeled to the Ethics Committee and the appropriate areas authorized to investigate and, if applicable, pursue cases in accordance with the applicable laws.

We believe that the regulations and mechanisms mentioned above, along with the legal framework applicable to us, will allow us to improve our ability to mitigate our exposure to bribery and corruption risks in our relationships with third parties. See "*Item 3—Key Information—Risk Factors—Risk Factors Related to Our Operations—We are subject to Mexican and international anti-corruption, anti-bribery, anti-money laundering or similar laws. Our failure to comply with these laws could result in penalties, which could harm our reputation and have an adverse effect on our business, results of operations and financial condition.*"

**Item 16K.&nbsp;&nbsp;&nbsp;&nbsp;Cybersecurity** 

***Risk Management and Strategy***

We have developed and implemented processes to assess, identify, and manage material risks from cybersecurity threats. Our cybersecurity processes leverage international best practices and standards issued by the U.S. National Institute of Standards and Technology (NIST), the International Organization for Standardizations (ISO), the International Society of Automation (ISA), the International Electrotechnical Commission (IEC), the American Institute of Certified Public Accountants (AICPA), the Cloud Security Alliance (CSA) and the Center for Internet Security (CIS), as well as those issued in this area by the Agency for Digital Transformation and Telecommunications (ATDT) of the Government of Mexico, and Mexican laws on personal data protection, among others.

Key elements of our cybersecurity risk management framework include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• risk assessments designed to identify, evaluate and prioritize cybersecurity risks to our critical infrastructure and our broader enterprise IT environment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• implementation of strategy on identity management, authentication and digital access controls;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• preparation of technical analyses and policies regarding cybersecurity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a security team principally responsible for designing, managing, monitoring and improving our cybersecurity risk and vulnerability assessment processes, architecture, security controls and responses to cybersecurity incidents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cybersecurity training for our employees, incident response personnel and senior management; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our *Centro de Respuesta a Incidentes de Ciberseguridad* (Cybersecurity Incident Response Center), which is responsible for cybersecurity incident prevention, monitoring, identification, containment, eradication, recovery and improvement efforts, including cyber intelligence, prevention and reporting of cyber fraud and extortion.

Our cybersecurity processes are integrated into our overall risk management system. We utilize our comprehensive *Marco de Administración de Riesgos Empresariales* (Enterprise Risk Management Framework, or "MARE") to assess, identify, and manage material risks, including risks related to cybersecurity threats or breaches, business disruption, financial reporting, industrial systems, intellectual property theft, fraud, extortion, employee or customer harm, system hacking, malware, cyberterrorism, misuse of information technology assets, internal control failures, information leakage, litigation, and legal and reputational risks.

We engage third parties in connection with our cybersecurity processes. This includes working with external experts to strengthen cybersecurity operations, validate and test our security architecture, manage vulnerabilities, train our personnel and address emerging threats. Our Cybersecurity Incident Response Center also collaborates with other specialized cybersecurity centers in Mexico, such as the *Centro de Respuesta a Incidentes Cibernéticos* managed by the National Guard, and receives information from reliable international sources to coordinate responses to cybersecurity events and incidents with specialized entities.

Moreover, our cybersecurity specialists maintain ongoing communication and collaboration with ATDT specialists of the Mexican Government to strengthen the prevention and management of emerging threats.

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

In an effort to mitigate risk factors associated with our third-party service providers, we routinely include confidentiality, intellectual property protection and personal data protection clauses in our contracts, conduct due diligence of third parties, including assessments of their information security strategies, policies and controls, and require operational technology service providers to comply with applicable cybersecurity standards and controls.See "*Item 3—Key Information—Risk Factors—Risk Factors Related to Our Operations—We are exposed to cybersecurity incidents and attacks that could materially adversely affect our business, results of operations and financial condition*".

***Governance***

*Board of Directors*

The Audit Committee of our Board of Directors is responsible for overseeing our overall risk management systems and processes and is primarily responsible for verifying compliance with our strategic objectives pursuant to our Business Plan. This includes preparing comparative analyses between the goals and commitments established in our Business Plan and the results achieved, as well as proposing adjustments and actions to our Board of Directors to correct any identified deficiencies.

Our Audit Committee and our Board of Directors receive monthly and annual reports on Information Technology matters from our *Unidad de Control Interno Institucional* (Institutional Internal Control Unit) and our Office of Internal Audit. Where applicable, these reports summarize our cybersecurity activities and incidents and include observations and recommendations to improve our procedural and operational management. Additionally, the Deputy Director of Information and Communications Technology monitors PEMEX's cybersecurity status on a daily basis and reports periodically to the Chief Administrative Services Officer and to the Risk Committee of Petróleos Mexicanos.

*Management* 

The cybersecurity risk management processes described above are implemented through our Information and Communications Technology Sub-Directorate and the Information Security Office. Alongside the Risk Committee of Petróleos Mexicanos, these areas are responsible for implementing strategies, initiatives, action plans and activities to strengthen cybersecurity management processes, issuing internal policies and regulations regarding cybersecurity, identity management, user access controls and the protection of sensitive digital information. It also considers solutions, tools and services contracted through specialized suppliers.

The Information and Communications Technology Sub-Directorate is composed of the Deputy Director, coordinators and managers. The Deputy Director is responsible, among other duties, for defining the Information Technology strategy and coordinating PEMEX's cybersecurity strategy. The Deputy Director has over three decades of experience in the design, implementation and management of technological solutions, and information security processes for incident response. He holds a degree in Computer Science with a focus on Systems Engineering, complemented by international programs in Digital Transformation and Executive Modernization. The coordinators supervise the managers to ensure that their functions are carried out in accordance with our cybersecurity strategy. Managers collaborate with specialists across the different technological domains to operate cybersecurity controls in accordance with our cybersecurity strategy.

The Information Security Office is led by the Information Security Manager and is composed of 30 professionals.

The Information Security Manager is an expert in cybersecurity management, with specialization in national security, and holds certifications including CISM, CRISC, CISA and ISO 22301.

The 30 professionals are experts and specialists in different cybersecurity matters and are continuously trained. Working in coordination with specialists across various technology domains, they collectively hold certifications such as Certified Information Security Manager (CISM), Certified Information Systems Security Professional (CISSP), Certified in Risk and Information Systems Control (CRISC), Certified Information Systems Auditor (CISA), GIAC Certified Forensic Analyst (GIAC-GCFA), Certified Secure Software Lifecycle Professional (CSSLP), ISO 22301 and 31000, ISO/IEC 27001 and 27017, Industrial Cybersecurity Implementation V3.20, Cybersecurity Certification CC (ISC)², CompTIA Security+ and eJPTv2 Certification.

Report of Independent Registered Public

Accounting Firm

**To the Board of Directors of** 

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies** 

**Opinion on the Consolidated Financial Statements** 

We have audited the accompanying consolidated statements of financial position of Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies (PEMEX) as of December 31, 2025 and 2024, the related consolidated statements of comprehensive income, changes in equity (deficit), and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of PEMEX as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025, in conformity with IFRS Accounting Standards as issued by the International Accounting Standards Board.

**Going Concern**

The accompanying consolidated financial statements have been prepared assuming that PEMEX will continue as a going concern. As discussed in Note 22 F to the consolidated financial statements, PEMEX has suffered recurring losses from operations and has a net equity deficiency. These factors raise substantial doubt about its ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 22 F. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

**Basis for Opinion**

These consolidated financial statements are the responsibility of PEMEX's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. 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 PEMEX 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 consolidated financial statements are free of material misstatement, whether due to error or fraud. PEMEX is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, 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.

![g310515dsp002a.jpg](ck0000932782-20251231_g3.jpg)<br>

Our audits included performing procedures to assess the risks of material misstatement of the consolidated 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 consolidated 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 consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matters**

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters 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 matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

*Impairment of certain exploration and extraction and industrial processes and energy transformation cash generating units. (000's mxp)* 

As discussed in notes 3 H and 12 to the consolidated financial statements, PEMEX recognized a net reversal of impairment of $14,950,790 in certain of the exploration and extraction and industrial processes and energy transformation ("upstream") cash generating units (CGUs) for the year ended December 31, 2025. At the end of each reporting period PEMEX assesses each of its CGUs for indicators of impairment and also assesses whether there is an indication that previously recognized impairment losses, except those related to goodwill, have reversed. When there is an indication of impairment and the carrying amount of a CGU exceeds its recoverable amount, PEMEX records an impairment charge in profit or loss. Impairment losses are reversed in subsequent periods if there is an indication that the impairment loss no longer exists or may have decreased and there has been an increase in the recoverable amount since the recognition of the impairment expense. The recoverable amount of a CGU is defined as the higher of its fair value minus the cost of disposal, and its value in use. The value in use is the present value of the estimated future net cash flows expected to arise from the continuing use of a CGU and from its disposal at the end of its useful life; discounted by applying a pre-tax discount rate. For the upstream CGUs, the recoverable amount was determined as the value in use and required the use of a number of assumptions, including the forecasted production of oil and gas proved and probable reserves, estimate of future operating and development costs for the exploration and production CGUs and the discount rate for all upstream CGUs.

We identified the assessment of certain assumptions used to determine the recoverable amount of the upstream CGUs as a critical audit matter. The estimation of the recoverable amount of these CGUs requires the use of subjective, significant assumptions in relation to the forecasted production of oil and gas proved and probable reserves, the future operating and development costs for the exploration and extraction CGUs and the discount rate for both the exploration and extraction and industrial processes and energy transformation CGUs. It required a high degree of subjective auditor judgment to evaluate these significant, judgmental assumptions.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design of certain internal controls related to the impairment assessment process, including controls related to the forecasted production of oil and gas proved and probable reserves, estimate of future operating and development costs and the discount rate. We evaluated the competence, capabilities and objectivity of PEMEX's internal petroleum reservoir engineers, who forecast the production of oil and gas proved and probable reserves. We compared the future production quantities forecast by PEMEX's internal petroleum reservoir engineers to the production used in the estimate of future net

cash flows. We developed our independent correlation calculations based on PEMEX's historical data and compared to PEMEX's correlation factors. We compared the future production costs and expenses used in the estimate of future net cash flows to historical data. In addition, we involved a valuation professional with specialized skills and knowledge, who assisted in evaluating PEMEX's discount rate, by comparing it against a discount rate range that was independently developed using publicly available market data for comparable entities.

*The impact of estimated proved oil and gas reserves on depreciation and amortization expenses related to producing oil and gas properties. (000's mxp)* 

As discussed in notes 3 E iii and 12 to the consolidated financial statements, PEMEX reported depreciation and amortization expenses related to producing oil and gas properties of $153,518,664 for the year ended December 31, 2025. PEMEX calculates depreciation and amortization expenses related to producing oil and gas properties using the unit of production method. Under this method, the capitalized costs of producing oil and gas properties, along with support equipment and facilities, are depreciated or amortized to profit or loss in proportion to the production of the proved oil and gas reserves. On an annual basis PEMEX's internal petroleum reservoir engineers use geological and engineering data as well as commercial and market information and estimates of development and production costs to estimate the proved oil and gas reserves. PEMEX engages external petroleum reservoir engineering specialists to evaluate these estimates.

We identified the impact of estimated proved oil and gas reserves on the depreciation and amortization expenses related to producing oil and gas properties as a critical audit matter. Complex auditor judgement was required to evaluate PEMEX's estimate of proved oil and gas reserves, which is the most significant judgmental input to the depreciation and amortization expenses calculation. The process for evaluating the proved oil and gas reserves is complex, involves a number of subjective assumptions and requires specialized skills and knowledge.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design of certain internal controls related to the determination of the estimate of proved oil and gas reserves, including controls related to the forecasted production of proved oil and gas reserves. We assessed the methodology used by PEMEX's internal petroleum reservoir engineers to estimate proved oil and gas reserves. We evaluated the professional qualifications and the knowledge, skills and ability of PEMEX'S internal petroleum reservoir engineers and the external petroleum reservoir engineering specialists engaged by PEMEX. We obtained the proved oil and gas reserves reports from the external petroleum reservoir engineering specialists and compared the information with that used by the internal petroleum reservoir engineers. We read the findings of the external petroleum reservoir engineering specialist's review of the methods and procedures used by PEMEX in estimating the proved reserves to assess compliance with industry and regulatory standards.

We have served as PEMEX's auditor since 2018.

**NOTE 1.&nbsp;&nbsp;&nbsp;&nbsp;STRUCTURE AND BUSINESS OPERATIONS OF PETRÓLEOS MEXICANOS, STATE-OWNED PUBLIC COMPANY AND SUBSIDIARY COMPANIES**

On August 11, 2014, the *Ley de Petróleos Mexicanos* (the "2014 Petróleos Mexicanos Law") was published in the Official Gazette of the Federation. The 2014 Petróleos Mexicanos Law became effective on October 7, 2014, except for certain provisions. On December 2, 2014, the *Secretaría de Energía* (the "Ministry of Energy") published in the Official Gazette of the Federation the declaration pursuant to which the special regime governing Petróleos Mexicanos' activities relating to productive state-owned subsidiaries, affiliates, compensation, assets, administrative liabilities, state dividend, budget and debt came into effect. On June 10, 2015, the *Disposiciones Generales de Contratación para Petróleos Mexicanos y sus Empresas Productivas Subsidiarias* (General Contracting Provisions for Petróleos Mexicanos and its productive state-owned subsidiaries) was published in the Official Gazette of the Federation and the following day the special regime for acquisitions, leases, services and public works matters came into effect.

Once the 2014 Petróleos Mexicanos Law came into effect, Petróleos Mexicanos was transformed from a decentralized public entity to a productive state-owned company. Petróleos Mexicanos is a legal entity empowered to own property and carry on business in its own name with the purpose of carrying out exploration and extraction of crude oil and other hydrocarbons in the United Mexican States ("Mexico"), as well as refining, processing, storing, transporting, selling and trading in these products.

On October 31, 2024, amendments to Articles 25, 27 and 28 of the Mexican Constitution were signed into law by President Claudia Sheinbaum Pardo and published in the Official Gazette of the Federation as the Energy Reform Decree. The Energy Reform Decree took effect on November 1, 2024 and transformed the legal regime of Petróleos Mexicanos from an *empresa productiva del Estado* (productive state-owned company) to an *empresa pública del Estado* (state-owned public company). The Energy Reform Decree reaffirmed the Mexican nation's ownership of the hydrocarbons located in Mexico's subsoil and included transitional articles setting forth the general framework and timeline for its implementation through secondary legislation.

On March 12, 2025, the Mexican Congress approved the secondary legislation, which was subsequently signed into law by President Claudia Sheinbaum Pardo and published in the Official Gazette of the Federation on March 18, 2025. The secondary legislation took effect on March 19, 2025 and included six new laws, including the *Ley de la Empresa Pública del Estado, Petróleos Mexicanos* (the "2025 Petróleos Mexicanos Law"). Pursuant to the 2025 Petróleos Mexicanos Law, Petróleos Mexicanos is wholly owned by the Mexican Government and categorized under the Ministry of Energy.

The 2025 Petróleos Mexicanos Law dissolved the subsidiary entities *Pemex Exploración y Producción* ("Pemex Exploration and Production"), *Pemex Transformación Industrial* ("Pemex Industrial Transformation") and *Pemex Logística* ("Pemex Logistics") each of which were, until March 19, 2025, productive state-owned subsidiaries of Petróleos Mexicanos empowered to own property and carry on business in their own name, subject to the direction and coordination of Petróleos Mexicanos. All of the assets, liabilities, rights and obligations of the subsidiary entities were assumed by, and transferred at historical cost without gain or loss to Petróleos Mexicanos and it became the successor of the subsidiary entities as a matter of Mexican law. The 2025 Petróleos Mexicanos Law does not affect any payment obligations previously contracted, nor does it alter the guarantees provided by Petróleos Mexicanos or the dissolved entities, whether in Mexico or abroad, where Petróleos Mexicanos is the beneficiary.

Prior to their dissolution, the primary purpose of the subsidiary entities, were as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pemex Exploration and Production: This entity was in charge of the exploration and extraction of crude oil and solid, liquid or gaseous hydrocarbons in Mexico, in the exclusive economic zone of Mexico and abroad, as well as drilling services and repair and services of wells;

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pemex Industrial Transformation: This entity performed activities related to refining, transformation, processing, importing, exporting, trading and the sale of hydrocarbons, petroleum products, natural gas and petrochemicals, as well as commercialized, distributed and traded methane, ethane and propylene, directly or through others; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pemex Logistics: This entity provided transportation, storage and related services for crude oil, petroleum products and petrochemicals to PEMEX (as defined below) and other companies, through pipelines and maritime and terrestrial means, and provided guard and management services.

Prior to the dissolution, the principal distinction between the subsidiary entities and the Subsidiary Companies (as defined below) was that the subsidiary entities were productive state-owned entities, whereas the Subsidiary Companies are affiliate companies that were formed in accordance with the applicable laws of each of the respective jurisdictions in which they were incorporated.

On May 22, 2025, the Board of Directors of Petróleos Mexicanos approved the *Estatuto Orgánico de Petróleos Mexicanos* (Organic Statute of Petróleos Mexicanos or the "New Organic Statute"). The New Organic Statute was published in the Official Gazette of the Federation on May 30, 2025, and became effective on June 1, 2025. On September 12, 2025, an amendment to the New Organic Statute, previously approved by the Board of Directors of Petróleos Mexicanos, was published in the Official Gazette of the Federation. The New Organic Statute establishes the new structure and organization of PEMEX. Changes derived from this new structure and how PEMEX's primary business are now conducted are disclosed in Note 6.

The "Subsidiary Companies" are defined as those companies which are controlled, directly or indirectly, by Petróleos Mexicanos. "Associates," as used herein, means those companies in which Petróleos Mexicanos has significant influence but not control or joint control over its financial and operating policies.

Petróleos Mexicanos, State-Owned Public Company and the Subsidiary Companies are referred to collectively herein as "PEMEX".

PEMEX's address and its principal place of business is: Av. Marina Nacional No. 329, Col. Verónica Anzures, Alcaldía Miguel Hidalgo, 11300, Ciudad de México, México.

**NOTE 2.&nbsp;&nbsp;&nbsp;&nbsp;AUTHORIZATION AND BASIS OF PREPARATION**

**Authorization** 

On April 21, 2026, these consolidated financial statements and the notes hereto were authorized for issuance by the following officers: Mr. Víctor Rodríguez Padilla, Chief Executive Officer, Mr. Juan Carlos Carpio Fragoso, Chief Financial Officer, Mr. Óscar René Orozco Piliado, Deputy Director of Accounting and Tax and Mr. Ernesto Balcázar Hernández, Associate Managing Director of Accounting.

These consolidated financial statements and the notes hereto are issued pursuant to the terms of Article 16 Fraction X of the *Ley de Empresa Pública del Estado, Petróleos Mexicanos (*"2025 Petróleos Mexicanos Law"), Article 104 Fraction III, paragraph a, of the *Ley del Mercado de Valores* ("Securities Market Law"), and of Article 33 Fraction I, paragraph a, section 3 and Article 78 of the *Disposiciones de carácter general aplicables a las emisoras de valores y a otros participantes del mercado de valores* ("General provisions applicable to securities' issuers and other participants of the securities market").

**Basis of preparation** 

**A.&nbsp;&nbsp;&nbsp;&nbsp;Statement of compliance**

PEMEX prepared its consolidated financial statements as of December 31, 2025 and 2024, and for the years ended December 31, 2025, 2024 and 2023, in accordance with IFRS Accounting Standards ("IFRS"), as issued by the International Accounting Standards Board.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

**B.&nbsp;&nbsp;&nbsp;&nbsp;Basis of accounting**

These consolidated financial statements have been prepared using the historical cost basis method, except for the following items, which have been measured using an alternative basis.

---

| | |
|:---|:---|
| **ITEM** | **BASIS OF MEASUREMENT** |
| Derivative Financial Instruments ("DFIs") | Fair Value |
| Employee Benefits | Fair Value of plan assets less present value of the obligation (defined benefit plan) |

---

**C.&nbsp;&nbsp;&nbsp;&nbsp;Going concern**

The consolidated financial statements have been prepared on a going concern basis, which assumes that PEMEX will be able to continue its operations and can meet its payment obligations for a reasonable period (See Note 22-F).

**D.&nbsp;&nbsp;&nbsp;&nbsp;Functional and reporting currency**

These consolidated financial statements are presented in Mexican pesos, which is both PEMEX's functional currency and reporting currency, due to the following:

i.&nbsp;&nbsp;&nbsp;&nbsp;The economic environment in which PEMEX operates is Mexico, where the legal currency is the Mexican peso;

ii.&nbsp;&nbsp;&nbsp;&nbsp;The budget through which Petróleos Mexicanos operate as entities of the Mexican Government, including the ceiling for personnel services, is elaborated, approved and exercised in Mexican pesos;

iii.&nbsp;&nbsp;&nbsp;&nbsp;Employee benefits provision was 36% and 29% of PEMEX's total liabilities as of December 31, 2025 and 2024, respectively. This provision is computed, denominated and payable in Mexican pesos; and

iv.&nbsp;&nbsp;&nbsp;&nbsp;Cash flows for payment of general expenses, taxes and duties are realized in Mexican pesos.

Although the sales prices of certain products are based on international U.S. dollar-indices, final domestic selling prices are governed by the economic and financial policies established by the Mexican Government. Accordingly, cash flows from domestic sales are generated and received in Mexican pesos.

With regards to PEMEX's foreign currency (export sales, borrowings, etc.), Mexico's monetary policy regulator, the Banco de México ("Mexican Central Bank"), requires that Mexican Government entities other than financial entities sell their foreign currency to the Mexican Central Bank in accordance with its terms, receiving Mexican pesos in exchange, which is the currency of legal tender in Mexico.

**Terms definition** 

References in these consolidated financial statements and the related notes to "pesos" or "Ps." refers to Mexican pesos, "U.S. dollars" or "U.S.$" refers to dollars of the United States of America, "yen" or "¥" refers to Japanese yen, "euro" or "€" refers to the legal currency of the European Economic and Monetary Union, "pounds sterling" or "£" refers to the legal currency of the United Kingdom and "Swiss francs" or "CHF" refers to the legal currency of the Swiss Confederation. Figures in all currencies are presented in thousands of the relevant currency unit, except exchange rates and product and share prices.

**E.&nbsp;&nbsp;&nbsp;&nbsp;Use of judgments and estimates**

The preparation of the consolidated financial statements in accordance with IFRS requires the use of estimates and assumptions made by PEMEX's management that affect the recorded amounts of assets and liabilities and the disclosures of contingent assets and liabilities as of the date of these consolidated financial statements, as well as the recorded amounts of income, costs and expenses during the year. Actual results may differ from these estimates.

ii.&nbsp;&nbsp;&nbsp;&nbsp;Measurement of fair values

Some of PEMEX's accounting policies and disclosures require the measurement of the fair values of financial assets and liabilities, as well as non-financial assets and liabilities.

PEMEX has an established control framework with respect to the measurement of fair values. This includes a valuation team that has overall responsibility for overseeing all significant fair value measurements, including Level 3 fair values.

The valuation team regularly reviews significant unobservable inputs and valuation adjustments. If third party information, such as broker quotes or pricing services, is used to measure fair values, then the valuation team assesses the evidence obtained from the third parties to support the conclusion that these valuations meet the requirements of IFRS, including the level in the fair value hierarchy in which the valuations should be classified.

When measuring the fair value of an asset or a liability, PEMEX uses market observable data as far as possible. Fair values are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (i.e., as prices) or indirectly (i.e., derived from prices).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs).

If the inputs used to measure the fair value of an asset or a liability might be categorized in different levels of the fair value hierarchy, then the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

PEMEX recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred.

**F.&nbsp;&nbsp;&nbsp;&nbsp;Convenience translations**

These consolidated financial statements are presented in Mexican pesos (reporting currency), which is the same as the recording currency and the functional currency of PEMEX. The U.S. dollar amounts shown in the consolidated statements of financial position, the consolidated statements of comprehensive income, the consolidated statements of changes in equity (deficit) and the consolidated statements of cash flows have been included solely for the convenience of the reader and are unaudited. Such amounts have been translated from amounts in pesos, as a matter of arithmetic computation only, at the exchange rate for the settlement of obligations in foreign currencies provided by the Mexican Central Bank and the *Secretaría de Hacienda y Crédito Público* ("Ministry of Finance and Public Credit" or "SHCP") at December 31, 2025 of Ps.17.9667 per U.S. dollar. Translations herein should not be construed as a representation that the peso amounts have been or could be converted into U.S. dollars at the foregoing or any other rate.

**NOTE 3.&nbsp;&nbsp;&nbsp;&nbsp;MATERIAL ACCOUNTING POLICIES**

PEMEX has consistently applied the following accounting policies to each of the periods presented in the preparation of its consolidated financial statements.

Below is a summary of the material accounting policies:

**A. Basis of consolidation**

The consolidated financial statements include the financial statements of Petróleos Mexicanos and those of its subsidiaries over which it has control.

i. Business combinations

PEMEX accounts for business combinations using the acquisition method when the acquired set of activities and assets meets the definition of a business and control is transferred to PEMEX. In determining whether a particular set of activities and assets is a business, PEMEX assesses whether the set of assets and activities acquired includes, at a minimum, an input and substantive process and whether the acquired set could produce outputs.

PEMEX has an option to apply a 'concentration test' that permits a simplified assessment of whether an acquired set of activities and assets is not a business. The optional concentration test is met if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets.

The consideration transferred in the acquisition is generally measured at fair value, as are the identifiable net assets acquired. Any goodwill that arises is tested annually for impairment. Any gain on a bargain purchase is recognized in profit or loss immediately. Transaction costs are expensed as incurred, except if related to the issue of debt or equity securities.

Any contingent consideration is measured at fair value at the date of acquisition. If an obligation to pay contingent consideration that meets the definition of a financial instrument is classified as equity, then it is not remeasured and settlement is accounted for within equity. Otherwise, other contingent consideration is remeasured at fair value at each reporting date and subsequent changes in the fair value of the contingent consideration are recognized in profit or loss.

ii. Subsidiaries

Subsidiaries are entities controlled by PEMEX. PEMEX "controls" an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and could affect those returns through its power over the entity. The financial statements of subsidiaries are included in the consolidated financial statements from the date on which control commences until the date on which control ceases.

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies**

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

For more information about the Subsidiary Companies, see Note 5.

iii. Non-controlling interests

Non-controlling interests are measured initially at their proportionate share of the acquiree's identifiable net assets at the date of acquisition. Changes in the ownership interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions.

iv. Loss of control

When PEMEX loses control over a subsidiary, it derecognizes the assets and liabilities of the subsidiary, and any related NCI and other components of equity. Any resulting gain or loss is recognized in profit or loss. Any interest retained in the former subsidiary is measured at fair value when control is lost.

v. Interests in equity-accounted investees

PEMEX's interests in equity-accounted investees comprise interests in associates and a joint venture.

Associates are those entities in which PEMEX has significant influence, but not control or joint control, over the financial and operating policies. A joint venture is an arrangement in which PEMEX has joint control, whereby PEMEX has rights to the net assets of the arrangement, rather than rights to its assets and obligations for its liabilities (joint operation).

Interests in associates and the joint venture are accounted for using the equity method. They are initially recognized at cost, which includes transaction costs. Subsequent to initial recognition, the consolidated financial statements include PEMEX's share of the profit or loss and other comprehensive income (OCI) of equity accounted investees, until the date on which significant influence or joint control ceases. Upon loss of significant influence over the associate or joint control over the joint venture, PEMEX measures and recognizes any retained investment at its fair value. Any difference between the carrying amount of the associate or joint venture upon loss of significant influence or joint control and the fair value of the retained investment and proceeds from disposal is recognized in profit or loss.

When the value of the share of losses exceeds the value of PEMEX's investment in an associate or joint venture, the carrying value of the investment, including any long-term investment, is reduced to zero and PEMEX ceases to recognize additional losses, except in cases where PEMEX is liable for obligations incurred by those associates and joint ventures.

vi. Transactions eliminated on consolidation

Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated. Unrealized gains arising from transactions with equity-accounted investees are eliminated against the investment to the extent of the PEMEX interest in the investee. Unrealized losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment.

**B. Foreign currency**

i. Foreign currency transactions

Transactions in foreign currencies are translated into the respective functional currencies of PEMEX companies at the exchange rates at the dates of the transactions.

Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency at the exchange rate at the reporting date. Non-monetary assets and liabilities that are measured at fair value in a foreign currency are translated into the functional currency at the exchange rate when the fair value was determined. Non-monetary items that are measured based on historical cost in a foreign currency are translated at the exchange rate at the date of the transaction.

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies**

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

Foreign currency differences are generally recognized in consolidated statements of comprehensive income and presented within foreign exchange.

ii. Foreign operation

The financial statements of foreign subsidiaries and associates are translated into the reporting currency by first identifying if the functional currency is different from the currency for recording the foreign operations, and, if so, the recording currency is translated into the functional currency and then into the reporting currency using the year-end exchange rate of each period for assets and liabilities reported in the consolidated statements of financial position; the historical exchange rate at the date of the transaction for equity items; and the exchange rate at the date of the transaction for income and expenses reported in the consolidated statement of comprehensive income.

Foreign currency differences are recognized in OCI and accumulated in the currency translation effect, except to the extent that the translation difference is allocated to NCI.

When a foreign operation is disposed of in its entirety or partially such that control, significant influence or joint control is lost, the cumulative amount in the translation reserve related to that foreign operation is reclassified to the consolidated statement of comprehensive income as part of the gain or loss on disposal. If PEMEX disposes of part of its interest in a subsidiary but retains control, then the relevant proportion of the cumulative amount is reattributed to NCI. When PEMEX disposes of only part of an associate or joint venture while retaining significant influence or joint control, the relevant proportion of the cumulative amount is reclassified to profit or loss.

**C. Financial instruments**

*i. Recognition and initial measurement* 

Financial assets and liabilities are initially recognized when these assets are contractually originated or acquired, or when these liabilities are contractually issued or assumed.

Financial assets and financial liabilities (unless it is an account receivable or account payable without a significant financing component) are measured and initially recognized at fair value, in the case of financial assets or liabilities not measured at fair value with changes through OCI, plus the transaction costs directly attributable to acquisition or issuance, when subsequently measured at amortized cost. An account receivable or account payable without a significant financing component is initially measured at the transaction price. If PEMEX determines that the fair value at the initial recognition differs from the transaction price, PEMEX shall recognize the difference between the fair value at initial the recognition and the transaction price in the consolidated statements of comprehensive income.

*ii. Classification and subsequent measurement*

**Financial Assets** 

On initial recognition, a financial asset is classified as measured at: Amortized Cost; Fair Value Through Other Comprehensive Income ("FVTOCI")–debt investment; FVTOCI–equity investment; or Fair Value Through Profit or Loss ("FVTPL").

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies**

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

Financial assets are not reclassified subsequent to their initial recognition unless PEMEX changes its business model for managing financial assets, in which case all affected financial assets are reclassified on the first day of the first reporting period following the change in the business model.

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>FINANCIAL ASSETS</u> | <u>MEASUREMENT</u> |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Amortized cost | A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL:<br>• it is held within a business model that has the objective of holding assets to collect contractual cash flows; and<br>• its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Debt investment | A debt instrument is measured at FVTOCI only if it meets both of the following conditions and is not designated as at FVTPL:<br>• it is held within a business model that has the objective of both collecting contractual cash flows and selling financial assets; and<br>• its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Equity investment | On initial recognition of an equity investment that is not held for trading, PEMEX may irrevocably elect to present subsequent changes in fair value in OCI. This election is made on an investment-by-investment basis. |

---

All financial assets not classified as measured at amortized cost or FVTOCI (as described above) are measured at FVTPL. This includes all derivative financial assets (see Note 18). On initial recognition, PEMEX may irrevocably designate a financial asset that otherwise meets the requirements to be measured at amortized cost or at FVOCI as FVTPL, if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise.

*Financial assets: Business model assessment* 

PEMEX assesses the objective of the business model in which a financial asset is held at a portfolio level because this best reflects the way the business is managed and information is provided to management. The information considered includes:

• the stated policies and objectives for the portfolio and the operation of those policies in practice, which include whether management's strategy focuses on earning contractual interest income, maintaining a particular interest rate profile, matching the duration of the financial assets to the duration of any related liabilities or expected cash outflows or realizing cash flows through the sale of the assets;

• how the performance of the portfolio is evaluated and reported to PEMEX management;

• the risk that affects the performance of the business model (and the financial assets held within that business model) and how those risks are managed;

• how managers of the business are compensated (e.g., whether compensation is based on the fair value of the assets managed or the contractual cash flows collected); and

• the frequency, volume and timing of sales in prior periods, the reasons for such sales and expectations about future sales activity.

Transfers of financial assets to third parties in transactions that do not qualify for derecognition are not considered sales for this purpose, consistent with PEMEX's continuing recognition of the assets.

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies**

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

Financial assets that are held for trading or managed and the performance of which is evaluated on a fair value basis are measured at FVTPL.

**Financial Asset: Assessment whether contractual cash flows are solely payments of principal and interest** 

For the purposes of this assessment, principal is defined as the fair value of the financial assets on initial recognition. Interest is defined as consideration for the time value of money and for the credit risk associated with the principal amount outstanding during the relevant period of time and for the basic lending risks and costs (e.g., liquidity risk and administrative costs), as well as profit margin.

In assessing whether the contractual cash flows are solely payments of principal and interest, PEMEX considers the contractual terms of the instrument, which includes assessing whether the financial asset contains a contractual term that could change the timing or amount of contractual cash flows such that it would not meet this condition. In making this assessment, PEMEX considers:

• contingent events that would change the amount or timing of cash flows;

• terms that may adjust the contractual coupon rate, including variable rate features;

• prepayment and extension features; and

• terms that limit PEMEX's claim to cash flows from specified assets (for example, non-recourse features).

A prepayment feature is consistent solely with the payments of principal and interest criterion if the prepayment amount substantially represents unpaid amounts of principal and interest on the principal amount outstanding, which may include reasonable additional compensation for early termination of the contract. Additionally, for a financial asset acquired at a significant discount or premium to its contractual par amount, a feature that permits or requires prepayment at an amount that substantially represents the contractual par amount plus accrued (but unpaid) contractual interest (which may also include reasonable additional compensation for early termination) is treated as consistent with this criterion if the fair value of the prepayment feature is insignificant at initial recognition.

**Financial assets: Subsequent measurement and gain and losses** 

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Financial assets at FVTPL | Financial assets at FVTPL are measured at fair value and changes therein, including any interest or dividend income, are recognized in profit or loss. |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Financial assets at amortized cost | These assets are subsequently measured at amortized cost using the effective interest method. The amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized in profit or loss. Any gain or loss on derecognition is recognized in profit or loss. |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Debt investments at FVOCI | These assets are subsequently measured at fair value. Interest income calculated using the effective interest method, foreign exchange gains and losses and impairment are recognized in profit or loss. Other net gains and losses are recognized in OCI. On derecognition, gains and losses accumulated in OCI are reclassified to profit or loss. |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Equity investments at FVOCI | These assets are subsequently measured at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of part of the cost of the investment. Other net gains and losses are recognized in OCI and are never reclassified to profit or loss. |

---

**Financial liabilities: Classification, subsequent measurement and gains and losses** 

Financial liabilities are classified as measured at amortized cost or FVTPL. A financial liability is classified as FVTPL if it is classified as held-for-trading, it is a derivative or it is designated as such on initial recognition. Financial liabilities at

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies**

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

FVTPL are measured at fair value and net gains and losses, including any interest expense, are recognized in profit or loss. Other financial liabilities are subsequently measured at amortized cost using the effective interest method.

Interest expense and foreign exchange gains and losses are recognized in profit or loss. Any gain or loss on derecognition is also recognized in profit or loss.

*iii. Derecognition*

**Financial assets**

PEMEX derecognizes a financial asset when the contractual rights to the cash flows from the financial asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all of the risks and rewards of ownership of the financial asset are transferred or in which PEMEX neither transfers nor retains substantially all of the risks and rewards of ownership and it does not retain control of the financial asset.

PEMEX enters into transactions whereby it transfers assets recognized in its statement of financial position but retains either all or substantially all of the risks and rewards of the transferred assets. In these cases, the transferred assets are not derecognized.

**Financial liabilities** 

PEMEX derecognizes a financial liability when its contractual obligations are discharged, cancelled or expired. PEMEX also derecognizes a financial liability when its terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value.

On derecognition of a financial liability, the difference between the carrying amount extinguished and the consideration paid (including any non-cash assets transferred or liabilities assumed) is recognized in profit or loss.

*iv. Offsetting*

Financial assets and financial liabilities are offset, and the net amount is presented in the statement of financial position when, and only when, PEMEX has a legally enforceable right to set off the amounts and it intends either to settle them on a net basis or to realize the asset and settle the liability simultaneously.

*v. Derivative financial instruments and hedge accounting* 

PEMEX uses DFIs to hedge the risk exposure in foreign currency, interest rate and the price of commodities related to its products. Embedded derivatives are separated from the host contract and accounted for separately if the host contract is not a financial asset and certain criteria are met.

These contracts are not accounted as designated hedging instruments. DFIs are accounted for as financial assets when the fair value is positive and as a financial liability when the fair value is negative.

*vi. Impairment*

**Financial instruments and contract assets** 

PEMEX recognizes loss allowances for Estimated Credit Losses ("ECLs") on:

• financial assets measured at amortized cost;

• debt investments measured at FVOCI; and

• contract assets.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

PEMEX measures loss allowances at an amount equal to lifetime ECL, except for the following, which are measured as 12-month ECLs:

• debt securities that are determined to have low credit risk at the reporting date; and

• other debt securities and bank balances for which credit risk (i.e., the risk of default occurring over the expected life of the financial instrument) has not increased significantly since initial recognition.

PEMEX considers a financial asset to be in default when the debtor is unlikely to pay its credit obligations to PEMEX in full, without recourse by PEMEX to actions such as guarantee redemption (if any is held). PEMEX considers that a debt instrument has a low credit risk when its credit rating is classified as "investment grade."

The investment grade classification is based on minimum credit ratings of Baa3 (Moody's) and BBB- (S&P and Fitch), as well as its equivalent in other rating agencies.

Lifetime ECLs are the credit losses that result from all possible default events over the expected life of a financial instrument.

12-month ECLs are the portion of ECLs that result from default events that are possible within the 12 months after the reporting date (or a shorter period if the expected life of the instrument is less than 12 months).

The maximum period considered when estimating ECLs is the maximum contractual period over which PEMEX is exposed to credit risk.

**Measurement of ECLs** 

ECLs are a probability-weighted estimate of credit losses. Credit losses are measured as the present value of all cash shortfalls (for example, the difference between the cash flows due to the entity in accordance with the contract and the cash flows that PEMEX expects to receive).

ECLs are discounted at the effective interest rate of the financial asset.

**Credit-impaired financial assets** 

At each reporting date, PEMEX assesses whether financial assets carried at amortized cost and debt securities at FVOCI are credit-impaired. A financial asset is 'credit-impaired' when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred.

Evidence that a financial asset is credit-impaired includes the following observable data:

• significant financial difficulty of the borrower or issuer;

• a breach of contract such as a default or being more than 90 days past due;

• the restructuring of a loan or advance by PEMEX on terms that it would not consider otherwise;

• it is probable that the borrower will enter bankruptcy or other financial reorganization; or

• the disappearance of an active market for a security because of financial difficulties.

**Presentation of allowance for ECL in the statement of financial position** 

Loss allowances for financial assets measured at amortized cost are deducted from the gross carrying amount of the assets.

(Figures stated in thousands, except as noted)

**Write-off** 

The gross carrying amount of a financial asset is written off when PEMEX has no reasonable expectation of recovering a financial asset in its entirety or a portion thereof. In the case of individual customers, PEMEX's policy is to cancel the gross carrying amount when the financial asset has met the uncollectibility report as established in the *Políticas Generales y Procedimientos para Cancelar Adeudos* (Procedure to Write-Off Financial Assets). For corporate customers, PEMEX individually makes an assessment with respect to the timing and amount of write-off based on whether there is a reasonable expectation of recovery. However, financial assets that are written off could still be subject to enforcement activities in order to comply with the PEMEX's procedures for recovery of amounts due.

**D. Inventories and cost of sales**

Inventories are valued at the lower of cost or net realizable value. Cost is determined based on the cost of production or acquisition of inventory and other costs incurred in transporting such inventory to its present location and in its present condition, using the average cost method. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated selling costs. The estimate takes into consideration, among other things, the decrease in the value of inventories due to obsolescence.

Cost of sales represents the cost of production or acquisition of inventories at the time of sale, increased, where appropriate, by declines in net realizable value of inventories during the year.

Advance payment to suppliers for inventory purchases are recognized as part of inventory when the risks and benefits of the ownership of the inventory have been transferred to PEMEX.

**E. Wells, pipelines, properties, plant and equipment**

*i. Recognition and measurement*

Items of wells, pipelines, properties, plant and equipment are recorded at acquisition or construction cost, which includes capitalized borrowing cost, less accumulated depreciation and accumulated impairment losses.

Initial costs of wells, pipelines, properties, plant and equipment are initially recorded at cost, which includes their original purchase price or construction cost, any costs attributable to bringing the assets to a working condition for their intended use and the costs of dismantling and removing the items and restoring the site on which they are located, including the estimated cost of plugging and abandoning wells.

The cost of financing projects that require large investments and financing incurred for projects, net of interest revenues from the temporary investment of these funds, is recognized as part of wells, pipelines, properties, plant and equipment when the cost is directly attributable to the construction or acquisition of a qualifying asset. The capitalization of these costs is suspended during periods in which the development of construction is interrupted, and its capitalization ends when the activities necessary for the use of the qualifying asset are substantially completed. All other financing costs are recognized in the consolidated statements of comprehensive income in the period in which they are incurred.

The cost of self-constructed assets includes the cost of materials and direct labor, interest on financing and any other costs directly attributable to start up. In some cases, the cost also includes costs of plugging of wells and removal at present value.

Expenditures related to the construction of wells, pipelines, properties, plant and equipment during the stage prior to commissioning are stated at cost as intangible assets or construction in progress, in accordance with the characteristics of the asset. Once the assets are ready for use, they are transferred to the respective component of wells, pipelines, properties, plant and equipment and depreciation or amortization begins.

If significant parts of an item of wells, pipelines, properties, plant and equipment have different useful lives, then they are accounted for as separate items (major components) of property, plant and equipment.

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies**

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

Any gain or loss on disposal of an item of wells, pipelines, properties, plant and equipment is recognized in profit or loss.

Advance payments for the acquisition of pipelines, properties, plant and equipment are also recognized in the line item of wells, pipelines, properties, plant and equipment when the risks and benefits of the ownership have been transferred to PEMEX.

*ii. Subsequent expenditure*

The costs of major maintenance or replacement of a significant component of an item of wells, pipelines, properties, plant and equipment are recognized in the carrying amount of the item if it is probable that the future economic benefits embodied within the component will flow to PEMEX and its cost can be measured reliably. The costs of recurring maintenance, repairs and renovations of wells, pipelines, properties, plant and equipment carried out to maintain the facilities in normal operation conditions are recognized in profit or loss as incurred.

*iii. Depreciation*

Depreciation and amortization of capitalized costs in wells are determined based on the estimated economic life of the field to which the wells belong, considering the relationship between the production of barrels of oil equivalent for the period and proved developed reserves of the field, as of the beginning of the period, with quarterly updates for new development investments.

Depreciation of other elements of pipelines, properties, plant and equipment is recognized in profit or loss on a straight-line basis over the estimated useful life of the asset, beginning as of the date that the asset is available for use, or in the case of construction, from the date that the asset is completed and ready for use.

The estimated useful lives of wells, pipelines, properties, plant and equipment for current and comparative periods are described in Note 12. Estimated useful lives of items of properties, plant and equipment are reviewed and updated prospectively if expectations differ from previous estimates.

**F. Intangible assets and oil and natural gas exploration and license, appraisal and development expenditure**

*i. Intangible assets*

Intangible assets acquired separately are measured at initial recognition at their acquisition cost. After the initial recognition, intangible assets are valued at their acquisition cost, less: (i) accumulated amortization, under the straight-line method during the estimated useful life of the intangible asset and (ii) accumulated impairment losses.

Subsequent expenditure is capitalized only when it increases the future economic benefits embodied in the specific asset to which it relates. All other expenditure is recognized in profit or loss as incurred.

Amortization is calculated to write off the cost of intangible assets less their estimated residual values using the straight-line method over their estimated useful lives and is generally recognized in profit or loss.

Software licenses are amortized over the lesser of their contract period or the remaining life of the asset to which they are associated.

The estimated useful lives of elements of intangible assets for current and comparative periods are described in Note 13.

The estimated useful lives and residual values of intangible assets are reviewed at each reporting date and adjusted if appropriate.

*ii. Wells not assigned to a reserve, oil and natural gas exploration, appraisal and development expenditure* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.Wells not assigned to a reserve

Wells not assigned to a reserve mainly include drilling, evaluation and development costs for oil and natural gas, and rights-of-way.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.Oil and natural gas exploration, appraisal and development expenditures

Oil and natural gas exploration, evaluation and development expenses are accounted for using the principles of the successful efforts method of accounting, as described below:

**Successful Efforts Method** 

Exploration and Extraction segment applies IFRS 6 - Exploration and Evaluation of Mineral Resources, which allows an entity to develop an accounting policy for exploration and evaluation assets. Therefore, the Exploration and Extraction segment uses the method of successful efforts, which requires a cause-and-effect relationship between the costs incurred and the recognition of specific reserves. Generally, if a cost is incurred without an identifiable future benefit, it is charged to expenses.

Before PEMEX is able to determine the accounting treatment of a cost, it must be classified as a property acquisition, exploration, development or production cost.

**Exploration and appraisal expenditure** 

Geological and geophysical exploration costs including topographic costs, geological studies, property access rights, remuneration and expenses of geologists and geophysicists are charged to expenses as incurred.

Costs directly associated with an exploration well, other than the costs mentioned in the preceding paragraph, are initially capitalized as an intangible asset (wells not assigned to a reserve) until the drilling of the well is complete and the results have been evaluated. These costs include employee compensation, materials and fuel used, platform costs and payments made to contractors.

If potentially commercial quantities of hydrocarbons are not found, the exploration well costs are written off against profit or loss. If hydrocarbons are found and, subject to additional assessment activity, are likely to be capable of commercial development, the costs continue to be carried as an asset. If it is determined that development will not occur, then the costs are expensed against profit or loss.

Costs directly associated with the evaluation activity performed to determine the size, characteristics and commercial potential of a reserve after the initial hydrocarbon discovery, including the costs of evaluation of wells where no hydrocarbons were found, are initially capitalized as an intangible asset (wells not assigned to a reserve). When proved reserves of oil and natural gas are determined and development is approved by management, the relevant expenditure is transferred to wells, pipelines, properties, plant and equipment.

Exploration wells more than 12 months old are recognized as an expense unless: (a)(i) they are in an area requiring major capital expenditure before production can begin, (ii) commercially productive quantities of reserves have been found, and (iii) they are subject to further exploration or appraisal activity, in that, either drilling or additional exploration wells are underway or firmly planned for the near future or (b) proved reserves are viable within 12 months of completion of the exploratory drilling.

**Development expenditure**

Expenditure on the construction, installation and completion of infrastructure facilities such as platforms, pipelines and the drilling of development wells, including service and unsuccessful development or delineation wells, is capitalized within

(Figures stated in thousands, except as noted)

wells, pipelines, properties, plant and equipment and is depreciated from the commencement of production as described in the accounting policy for wells, pipelines, properties, plant and equipment.

**Exploration** 

Exploration includes all expenses related to the search for oil and / or gas reserves, including depreciation and applicable costs of supporting equipment and facilities, and the costs of drilling exploratory wells and exploratory stratigraphic wells. Some exploration costs are charged directly to expenses when they occur, such as the costs of maintaining unexploited properties, since such costs do not increase the possibilities that said lands contain proven reserves. The costs of geologists, topographers and geophysicists, including wages and other related expenses, are also charged directly to expenses when they occur because they do not represent the acquisition of an identifiable asset since these studies represent research expenses.

All costs for drilling exploratory wells are capitalized and classified as wells, pipelines, property, plant and equipment, not associated with a reserve, until it is determined whether or not a well has proven reserves. Once the exploratory wells are completed, the future treatment of these costs is determined.

**Development** 

Development costs are associated with previously discovered proven reserves, with previously known future benefits. Therefore, all costs incurred in development activities must be capitalized.

Development includes all costs incurred in creating a system of productive wells, related equipment, and facilities in proven reserves so that oil and / or gas can be extracted. Developmental costs are related to specific proven reserves. The cost of building roads to gain access to proven reserves is a development cost, as is the cost of providing facilities for the extraction, treatment, collection and storage of oil and / or gas. Developmental costs also include depreciation and operating costs of equipment and facilities used in developmental activities. Likewise, non-productive development wells are capitalized, since they are considered as a cost of creating the total production system for proven reserves.

**Production** 

Production includes the costs incurred to raise oil and / or gas to the surface, its collection, treatment, processing and field storage.

The production function ends in the storage tank of the production field or, in exceptional circumstances, at the first point of delivery of the oil and / or gas to the main line, refinery, marine terminal or common transport.

**G. Crude oil and natural gas reserves** 

Under Mexican law, all crude oil and other hydrocarbon reserves located in the subsoil of Mexico are owned by the Mexican nation and not by PEMEX. In accordance with the aforementioned and based on the applicable regulation as of the date of these consolidated financial statements, the reserves assigned to PEMEX by the Mexican Government are not registered for accounting purposes because they are not PEMEX's property. PEMEX estimates total proved oil and natural gas reserve volumes in accordance with the definitions, methods and procedures established in Rule 4-10(a) of Regulation S-X ("Rule 4-10(a)") of the U.S. Securities and Exchange Commission ("SEC"), as amended, and where necessary, in accordance with the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers (the "SPE") as of February 19, 2007. These procedures are consistent with international reserves reporting practice.

The estimation of these reserves depends on assumptions made and the interpretation of the data available and may vary among analysts. The results of drilling activities, test wells and production after the date of estimation are utilized in future revisions of reserves estimates.

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies**

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

Although PEMEX does not own the oil and other hydrocarbon reserves within Mexico, these procedures allow PEMEX to record the effects that such oil and other hydrocarbon reserves have on its consolidated financial statements, including, for example, in the depreciation and amortization line item.

**H. Impairment of non-financial assets**

The carrying amounts of PEMEX's non-financial assets, other than inventories and deferred taxes, are assessed for indicators of impairment at the end of each reporting period. If the net carrying value of the asset or its cash-generating unit exceeds the recoverable amount, PEMEX records an impairment charge in profit or loss.

A cash-generating unit is the smallest identifiable group of assets which can generate cash flows independently from other assets or groups of assets.

The recoverable amount of an asset or a Cash-Generating Unit ("CGU") is defined as the higher of its fair value minus the costs of disposal and its value in use. The value in use is the discounted present value of the net future cash flows expected to arise from the continuing use of an asset and from its disposal at the end of its useful life. In measuring value in use, the discount rate applied is the pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the asset. Fair value is calculated using discounted cash flows determined by the assumptions that market participants would apply in order to estimate the price of an asset or CGU, assuming that such participants were acting in their best economic interest.

In the case of cash-generating assets or items dedicated to the exploration and evaluation of hydrocarbons reserves, the recoverable amount is determined using the value in use based on the proved reserves and probable reserves, in some cases, for the risk factor associated with such reserves.

Both impairment losses and reversals are recognized in the statement of comprehensive income in the costs and expenses line items in which the depreciation and amortization are recognized. Impairment losses may not be presented as part of the costs that have been capitalized in the value of any asset. Impairment losses related to inventories are recognized as part of cost of sales. Impairment losses on investments in associates, joint ventures and other investments are recognized as profit (loss) sharing in associates.

An impairment loss shall be reversed if there has been a change in the estimates used since the date when the impairment loss was recognized. These reversals will not exceed the carrying value of the asset as though no impairment had been recognized. Impairment losses and reversals are presented in a separate line item in the consolidated statement of comprehensive income.

**I. Leases**

At the inception of a contract, PEMEX assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

*i. As a lessee* 

At commencement or on modification of a contract that contains a lease component, PEMEX allocates the consideration in the contract to each lease component on the basis of its relative stand-alone prices. However, PEMEX has elected for some leases not to separate non-lease components and to account for the lease and non-lease components as a single lease component.

PEMEX recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received.

------

**<u>[**Table of Contents**](#i4566749d23c04ea7b50812638080ef9e_7)</u>**

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies**

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

The right-of-use asset is subsequently depreciated using the lesser of the straight-line method and the hours of use method, from the commencement date to the end of the lease term, unless the lease transfers ownership of the underlying asset to PEMEX by the end of the lease term or the cost of the right-of-use asset reflects that PEMEX will exercise a purchase option. In that case, the right-of-use asset will be depreciated over the useful life of the underlying asset, which is determined on the same basis as those of property and equipment. In addition, the right-of-use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability. Useful lives are shown in Note 16.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, PEMEX's incremental borrowing rate. Generally, PEMEX uses its incremental borrowing rate as the discount rate.

PEMEX determines its incremental borrowing rate by obtaining interest rates from various external financing sources and makes certain adjustments to reflect the terms of the lease and type of the asset leased.

Lease payments included in the measurement of the lease liability comprise the following:

• fixed payments, including in-substance fixed payments;

• variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date;

• amounts expected to be payable under a residual value guarantee; and

• the exercise price under a purchase option that PEMEX is reasonably certain to exercise, lease payments in an optional renewal period if PEMEX is reasonably certain to exercise an extension option, and penalties for early termination of a lease unless PEMEX is reasonably certain not to terminate early.

The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change in future lease payments arising from a change in an index or rate, if there is a change in PEMEX's estimate of the amount expected to be payable under a residual value guarantee, if PEMEX changes its assessment of whether it will exercise a purchase, extension or termination option or if there is a revised in-substance fixed lease payment.

When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use asset or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero.

PEMEX presents separately the right-of-use assets and lease liabilities in the statement of financial position.

**Short-term leases and leases of low-value assets**

PEMEX has elected not to recognize right-of-use assets and lease liabilities for leases of low-value assets and short-term leases. PEMEX recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term.

*ii. As a lessor* 

At inception or upon modification of a contract that contains a lease component, PEMEX allocates the consideration in the contract to each lease component on the basis of their relative stand-alone prices.

When PEMEX acts as a lessor, it determines at lease inception whether each lease is a finance lease or an operating lease.

To classify each lease, PEMEX makes an overall assessment of whether the lease transfers substantially all of the risks and rewards incidental to ownership of the underlying asset. If this is the case, then the lease is a finance lease; if not, then it is an operating lease. As part of this assessment, PEMEX considers certain indicators such as whether the lease is for the major part of the economic life of the asset.

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies**

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

If an arrangement contains lease and non-lease components, then PEMEX applies IFRS 15 to allocate the consideration in the contract.

PEMEX applies the derecognition and impairment requirements in IFRS 9 to the net investment in the lease. Further, PEMEX regularly reviews estimated unguaranteed residual values used in calculating the gross investment in the lease.

PEMEX recognizes lease payments received under operating leases as income on a straight-line basis over the lease term as part of "other revenue."

**J. Provisions**

Provisions are determined by discounting the expected future cash flows at a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability. The unwinding of the discount is recognized as finance cost.

PEMEX recognizes provisions when, as a result of a past event, PEMEX has incurred a legal or assumed present obligation for which a future disbursement is probable and the value of such disbursement is reasonably estimable. In certain cases, such amounts are recorded at their present value.

Increases in ongoing legal expense liabilities are recognized in the Consolidated Statement of Comprehensive Income in the "Other expenses" line item.

**Environmental liabilities** 

In accordance with applicable legal requirements and accounting practices, an environmental liability is recognized when the cash outflows are probable and the amount is reasonably estimable. Disbursements related to the conservation of the environment that are linked to revenue from current or future operations are accounted as expenses or assets, depending on the circumstances of each disbursement. Disbursements related to past operations, which no longer contribute to current or future revenues, are accounted for as current period expenses.

The accrual of a liability for a future disbursement occurs when an obligation related to environmental remediation, for which PEMEX has the information necessary to determine a reasonable estimated cost, is identified. Increases in environmental liabilities are recognized in the Consolidated Statement of Comprehensive Income in the "Cost of sales" line item.

**Retirement of assets** 

The obligations associated with the future retirement of assets, including those related to the retirement of wells, pipelines, properties, plant and equipment and their components are recognized at the date that the retirement obligation is incurred, based on the discounted cash flow method. The determination of the fair value is based on existing technology and regulations. If a reliable estimation of fair value cannot be made at the time the obligation is incurred, the accrual will be recognized when there is sufficient information to estimate the fair value.

The obligations related to the costs of future retirement of assets associated with the principal refining processes for gas and petrochemicals are not recognized. These assets are considered to have an indefinite useful life due to the potential for maintenance and repairs.

The abandonment costs related to wells currently in production and wells temporarily closed are recorded in the statement of comprehensive income based on the units of production method. Total cost of abandonment and plugging for non-producing wells is recognized in the statement of comprehensive income at the end of each period. All estimations are based on the useful lives of the wells, considering their discounted present value. Salvage values are not considered, as these values commonly have not traditionally existed. Increases in retirement of assets liabilities are recognized as part of the cost of completed wells in fixed assets.

(Figures stated in thousands, except as noted)

**K. Employee benefits**

*i. Short-term employee benefits*

Short-term employee benefits are expensed as the related service is provided. A liability is recognized for the amount expected to be paid if PEMEX has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee and the obligation can be estimated reliably.

*ii. Defined contribution plans*

Obligations for contributions to defined contribution plans are expensed as the related service is provided. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in future payments is available.

*iii. Defined benefit plan*

PEMEX's net obligation in respect of defined benefit plans is calculated separately for each plan by estimating the amount of future benefit that employees have earned in the current and prior periods, discounting that amount and deducting the fair value of any plan assets.

The calculation of defined benefit obligations is performed annually by a qualified actuary using the projected unit credit method. When the calculation results in a potential asset for PEMEX, the recognized asset is limited to the present value of economic benefits available in the form of any future refunds from the plan or reductions in future contributions to the plan. To calculate the present value of economic benefits, consideration is given to any applicable minimum funding requirements.

New remeasurements of the net defined benefit liability, which comprise actuarial gains and losses, the return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognized immediately in OCI. PEMEX determines the net interest expense (income) on the net defined benefit liability (asset) for the period by applying the discount rate used to measure the defined benefit obligation at the beginning of the annual period to the net defined benefit liability (asset) at such time, considering any changes in the net defined benefit liability (asset) during the period as a result of contributions and benefit payments. Net interest expense and other expenses related to defined benefit plans are recognized in profit or loss.

When the benefits of a plan are changed or when a plan is curtailed, the resulting change in benefit that relates to past service or the gain or loss on curtailment is recognized immediately in profit or loss. PEMEX recognizes gains and losses from the settlement of a defined benefit plan when the settlement occurs.

*iv. Other long-term employee benefits*

PEMEX's net obligation in respect of long-term employee benefits is the amount of future benefit that employees have earned in return for their service in the current and prior periods. That benefit is discounted to determine its present value. New remeasurements are recognized in profit or loss in the period in which they arise.

*v. Termination benefits*

Termination benefits are expensed at the earlier of when PEMEX can no longer withdraw its offer of those benefits and when PEMEX recognizes costs for a restructuring. If benefits are not expected to be settled in full within 12 months of the reporting date, then they are discounted.

**L. Income taxes, duties and royalties**

Income tax expense comprises current and deferred tax. It is recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or in OCI.

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies**

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

The interest and penalties related to income taxes, including uncertain tax treatments, do not meet the definition of income taxes, and are therefore accounted for under IAS 37 "Provisions, Contingent Liabilities and Contingent Assets."

*i. Current income tax*

Current income tax comprises the expected tax payable or receivable on the taxable income or loss for the year and any adjustment to the tax payable or receivable in respect of previous years. The amount of current tax payable or receivable is the best estimate of the tax amount expected to be paid or received that reflects uncertainty related to income taxes, if any. It is measured using tax rates enacted or substantively enacted at the reporting date. Current tax also includes any tax arising from dividends.

Current tax assets and liabilities are offset only if certain criteria are met.

*ii. Deferred income tax*

Deferred income tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax is not recognized for:

• temporary differences on the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss;

• temporary differences related to investments in subsidiaries, associates and joint arrangements to the extent that PEMEX is able to control the timing of the reversal of the temporary differences and it is probable that they will not reverse in the foreseeable future; and

• taxable temporary differences arising from the initial recognition of goodwill.

Temporary differences in relation to a right-of-use asset and a lease liability for a specific lease are regarded as a net package (the lease) for the purpose of recognizing deferred tax.

Deferred tax assets are recognized for unused tax losses, unused tax credits and deductible temporary differences to the extent that it is probable that future taxable profits will be available against which they can be used. Future taxable profits are determined based on the reversal of relevant taxable temporary differences. If the amount of taxable temporary differences is insufficient to recognize a deferred tax asset in full, then future taxable profits, adjusted for reversals of existing temporary differences, are considered, based on the business plans of PEMEX. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefit will be realized. Such reductions are reversed when the probability of future taxable profits improves.

Unrecognized deferred tax assets are reassessed at each reporting date and recognized to the extent that it has become probable that future taxable profits will be available against which they can be used.

Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, using tax rates enacted or substantively enacted at the reporting date.

The measurement of deferred tax reflects the tax consequences that would follow from the manner in which PEMEX expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities.

Deferred tax assets and liabilities are offset only if certain criteria are met.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

*iii. Duties, royalties and considerations*

**Duties** 

Until December 31, 2024, PEMEX was subject to taxes and special duties, which were based on the value of hydrocarbons extracted, with certain deductions. Such taxes and duties were recognized in accordance with IAS 12, Income Taxes (IAS 12), when they met the definition of income taxes. This occurs when such taxes and duties are set by a governmental authority and are determined based on a formula that considers net income (or hydrocarbon extraction measured at a sales price) after deducting allowable expenses. Accordingly, current income tax and deferred income tax were recognized in accordance with IAS 12.

Taxes and duties that do not meet the definition of income taxes under IAS 12 are recognized as costs or expenses, according to their nature. This includes the *Derecho Petrolero para el Bienestar* (Welfare Oil Duty), which became effective as of January 1, 2025 (see Note 21).

**Royalties and considerations** 

Royalties and considerations are payable pursuant to license agreements. These royalties are recognized as liabilities and affect the items of costs and expenses related to the operations that gave rise to them.

**M. Contingencies** 

Contingency losses are recorded when it is probable that a liability has been incurred and the amount thereof can be reasonably estimated. When a reasonable estimation cannot be made, qualitative disclosure is provided in the notes to the consolidated financial statements. Contingent assets are not recognized until realization is assured.

**N. Government grants (Revenues from FONADIN)**

Government grants related to assets are initially recognized as deferred income at fair value if there is reasonable assurance that they will be received and PEMEX will comply with the conditions associated with the grant. Grants related to the acquisition of assets are recognized in profit or loss as other income on a systematic basis over the useful life of the asset.

Grants that compensate expenses incurred are recognized in profit or loss as other income on a systematic basis in the periods in which the expenses are recognized, unless the conditions for receiving the grant are met after the related expenses have been recognized. In this case, the grant is recognized when it becomes receivable.

**O. Fair value** 

'Fair value' is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or, in its absence, the most advantageous market to which PEMEX has access at that date. The fair value of a liability reflects its non-performance risk.

A number of PEMEX accounting policies and disclosures require the measurement of fair values, for both financial and non-financial assets and liabilities (see Note 8).

When one is available, PEMEX measures the fair value of an instrument using the quoted price in an active market for that instrument. A market is regarded as 'active' if transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis.

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies**

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

If there is no quoted price in an active market, then PEMEX uses valuation techniques that maximize the use of relevant observable inputs and minimize the use of unobservable inputs. The chosen valuation technique incorporates all of the factors that market participants would take into account in pricing a transaction.

If an asset or a liability measured at fair value has a bid price and an ask price, then PEMEX measures assets and long positions at the bid price and liabilities and short positions at the ask price.

The best evidence of the fair value of a financial instrument on initial recognition is normally the transaction price (i.e., the fair value of the consideration given or received in a third-party transaction). If PEMEX determines that the fair value on initial recognition differs from the transaction price and the fair value is evidenced neither by a quoted price in an active market for an identical asset or liability nor based on a valuation technique for which any unobservable inputs are judged to be insignificant in relation to the measurement, then the financial instrument is initially measured at fair value, adjusted to defer the difference between the fair value on initial recognition and the transaction price. Subsequently, that difference is recognized in profit or loss on an appropriate basis over the life of the instrument but no later than when the valuation is fully supported by observable market data or the transaction is closed out.

**P. Revenue from contracts with customers**

Revenue is measured based on the consideration specified in a contract with a customer. PEMEX recognizes revenue when it transfers control over a good or service to a customer. The transaction price is established at the time of sale, including the estimate of the variable consideration (see Note 7).

**Q. Operating segments**

Operating segments are identifiable components of PEMEX that pursue business activities from which PEMEX earns revenues and incurs expenses and for which information is available to management on a segmented basis and is assessed by the Board of Directors in order to allocate resources and assess the profitability of the segments.

**R. Presentation of consolidated statements of comprehensive income**

Revenues, costs and expenses shown in PEMEX's consolidated statements of income are presented based on their function, which allows for a better understanding of the components of PEMEX's operating income. This classification allows for a comparison to the industry to which PEMEX belongs.

*i. Operating (loss) income*

Operating (loss) income is the result generated from the continuing principal revenue-producing activities of PEMEX as well as other income and expenses related to operating activities. Operating (loss) income excludes net finance costs, profit sharing in associates and income taxes and duties.

**Revenues** 

Represents revenues from the sale of products or services.

**Cost of sales** 

Cost of sales represents the acquisition and production costs of inventories, (depreciation, amortization, salaries, wages and benefits, including a portion of the cost of the reserve for employee benefits and operating expenses related to the production process), production taxes and duties, impairment, exploration costs, non-operating costs, among others.

**Other revenues and other expenses** 

Other revenues and other expenses consist primarily of income and expenses that are not related directly to the operation of PEMEX.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

**Distribution, transportation and sale expenses** 

Transportation, distribution and sale expenses are costs in connection with the storage, sale and delivery of products, such as the depreciation and operating expenses associated with these activities.

**Administrative expenses** 

Administrative expenses are costs related to PEMEX's areas that provide administrative support.

*ii. Financing income and financing cost and derivative financial instruments income (cost), net* 

**Financing income** 

Financing income is comprised of interest income, financial income and other income from financial operations.

**Financing cost** 

Financing cost is comprised of interest expenses, commissions and other expenses related to PEMEX's financing operations less any portion of the financing cost that is capitalized.

When calculating interest income and expenses, the effective interest rate is applied to the gross carrying amount of the asset (when the asset has no credit impairment), to the amortized cost of the liability or to the present value lease liabilities. However, for financial assets with credit impairment after initial recognition, interest income is calculated by applying the effective interest rate at the amortized cost of the financial asset. If the asset ceases to be impaired, the interest income calculation returns to the gross base.

**Derivative financial instruments (cost) income, net** 

Includes the result of changes in the fair value of derivative financial instruments (see Note 18).

**S. Incentive for automotive fuels**

On March 4, 2022, the federal government issued a decree that established a tax incentive applicable to entities subject to the *Impuesto Especial sobre Producción y Servicios* (Special Tax on Production and Services). Pursuant to this stimulus, PEMEX can recover the difference between the international reference price of gasoline and the price at which the gasoline is traded in the domestic market. This stimulus is known as the "automotive incentive."

The decree quantifies the automotive incentive based on the volume of fuel sold by applying a rate issued by the SHCP on a weekly basis. The decree also refers to the general rules issued by the SHCP that dictate the procedures to request the amount of the automotive incentive. The automotive incentive is measured based on the volume sold and the rates authorized in accordance with the decree and is recognized as income when the customer obtains control of the fuel when it is delivered to its facilities. At the same time, a revenue and an account receivable from the SHCP are recognized. The application for the automotive incentive is generally submitted during the first 17 days of the month following the month in which the automotive incentive was generated and is recovered during the 30 days following the application. The Industrial Processes segment (formerly Pemex Industrial Transformation, see Note 1) does not have any performance obligations to comply with in order to qualify for the automotive incentive, except for the sale of fuel to third parties, which is what gives rise to the incentive under the decree. Since fuel returns are not accepted, the automotive incentive does not require these considerations in its quantification.

Pursuant to the decree, the automotive incentive is not subject to the *Impuesto sobre la Renta* (Income Tax Law), and therefore it is considered non-cumulative income for the purposes of the Income Tax Law.

(Figures stated in thousands, except as noted)

**T. Renewable fuels obligation**

PEMEX is required to comply with the Renewable Fuel Standard implemented by the U.S. Environmental Protection Agency ("EPA"), which establishes annual quotas for the quantity of renewable fuels (such as ethanol) that must be blended into motor fuels consumed in the United States. PEMEX's renewable fuels obligations are based on a percentage of domestic product shipments as established by the EPA. To comply with such requirements PEMEX is required to purchase Renewable Identification Numbers ("RINs"). To the extent PEMEX is unable to blend the required amount of biofuels to satisfy its RINs obligations, PEMEX must purchase RINs on the open market to avoid penalties and fines.

PEMEX recognizes RINs as intangible assets and are initially measured at their fair value, which is determined based on the market price of RINs traded on the platform at that date. Issuance of RINs purchased on the trading platform are measured at cost. After initial recognition, RINs are measured based at first-entry first-output method.

PEMEX recognizes an obligation to deliver RINs to the extent that it emits pollutants. PEMEX measures the liability based on the carrying value of the available RINs to the extent that the emissions are within the annual limit, and the present market value of the certificates to the extent that additional certificates are required to settle the obligation. The liability is presented as a provision and is terminated when RINs are delivered to the U.S. Government.

**NOTE 6.&nbsp;&nbsp;&nbsp;&nbsp;SEGMENT FINANCIAL INFORMATION**

PEMEX's primary business is the exploration and extraction of crude oil and natural gas, as well as the production, processing, marketing and distribution of petroleum and petrochemical products. As of December 31, 2024 PEMEX's operations were conducted through seven business segments:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Exploration and Production;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Industrial Transformation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Logistics;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Deer Park;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Trading Companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Corporate; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Other Operating Subsidiary Companies.

Following the dissolution of the subsidiary entities on March 19, 2025 and pursuant to the New Organic Statute, as of June 1,

2025, PEMEX's operations are now conducted through six segments:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Exploration and Extraction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Industrial Processes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Energy Transformation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Deer Park;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Trading Companies; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Other Operating Subsidiary Companies.

The primary sources of revenue for PEMEX's business segments are as described below:

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies**

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Exploration and Extraction segment (formerly Exploration and Production) earns revenues from domestic sales of crude oil and natural gas, and from exporting crude oil through certain of the Trading Companies. Crude oil export sales are made through the agent subsidiary company PMI CIM, to 14 major customers in various foreign markets. Approximately half of PEMEX's crude oil is transferred to the Industrial Processes segment. Additionally, it receives income from drilling services, and servicing and repairing wells.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Industrial Processes segment (formerly Industrial Transformation) earns revenues from sales of refined petroleum products and derivatives, mainly to third parties within the domestic market. This segment also sells a significant portion of the fuel oil it produces to the *Comisión Federal de Electricidad* (Federal Electricity Commission, or "CFE") and a significant portion of jet fuel produced to the *Aeropuertos y Servicios Auxiliares* (Airports and Auxiliary Services Agency or " ASA "). The refining segment's most important products are different types of gasoline and diesel.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Energy Transformation segment (previously included in the Industrial Transformation segment) earns revenues from domestic sources generated by sales of natural gas, liquefied petroleum gas, naphtha, butane and ethane and certain other petrochemicals such as methane derivatives, ethane derivatives, aromatics, ammonia, fertilizers and its derivatives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Deer Park segment includes DPRLP's operations, generates revenues from sales of distillates and gasoline in the U.S. market.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Trading Companies segment, which consists of PMI CIM, PMI NASA, PMI Trading, MGAS and GASOB (the "Trading Companies"), earns revenues from trading crude oil, gas and petroleum and petrochemical products in international markets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The segment related to the Other Operating Subsidiary Companies provides transportation and storage of crude oil, petroleum products and petrochemicals, administrative, financing, consulting and logistical services, as well as economic, tax and legal advice and re-insurance services to PEMEX's subsidiary companies with industrial activities. As of March 19, 2025 this segment includes the Logistics and Corporate activities, previously reported as separate segments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Logistics segment (until March 18, 2025) earned income from transportation and storage of crude oil, petroleum products and petrochemicals, as well as related services, which it provides by employing pipelines and offshore and onshore resources, and from providing services related to the maintenance, handling, guarding and management of these products. As of March 19, 2025, this activity is included in the Other Operating Subsidiary Companies segment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Corporate segment (until March 18, 2025) provided administrative, financing and consulting services to PEMEX's subsidiary entities and companies. As of March 19, 2025, this activity is included in the Other Operating Subsidiary Companies segment.

The following tables present the condensed financial information of these segments, after elimination of unrealized intersegment gain (loss), and include only select line items. The columns before intersegment eliminations include unconsolidated figures. As a result, the line items presented below may not total. These reporting segments are those which PEMEX's management evaluates in its analysis and on which it bases its decision-making. These reporting segments are presented in PEMEX's reporting currency.

(Figures stated in thousands, except as noted)

For the year ended December 31, 2024, PEMEX presents the operating segments as they existed prior to the enactment of the 2025 Petróleos Mexicanos Law and the New Organic Statute, this information is not comparable to the 2025 amounts due to the unavailability to obtain these figures. For the year ended December 31, 2025, PEMEX presents the operating segments in accordance with PEMEX's new organizational structure under the New Organic Statute (see Note 1).

**Nature, performance obligations and timing of revenue recognition-** 

Revenue is measured based on the consideration specified in a contract with a customer. PEMEX recognizes revenue when it transfers control over a good or service to a customer.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

The following table provides information about the nature and timing of the satisfaction of performance obligations in contracts with customers, including significant payment terms and the related revenue.

---

| | | |
|:---|:---|:---|
| **Products / services** | **Nature, performance obligations** | **Timing of revenue recognition** |

| Sale of petroleum products | For all petroleum products, there is only one performance obligation that includes transport and handling services to the point of delivery.<br>The price is determined based on the price at the point of delivery, adding the price of the services rendered (freight, handling of jet fuel, etc.) with the provisions and terms established by the *Comisión Reguladora de Energía* (Energy Regulatory Commission or "CRE").  | Revenue is recognized at a point in time when control is transferred to the customer, which occurs either at the point of shipping or when it is delivered at the customer's facilities. Therefore, transportation fees can be included in the price of sale of the product and are considered part of a single performance obligation since transportation is rendered before control is transferred.<br>Revenue is initially measured by estimating variables such as quality and volume claims, etc. Invoices are usually payable within 30 days. |

| | | |
|:---|:---|:---|
| **Products / services** | **Nature, performance obligations** | **Timing of revenue recognition** |
| Sales of natural gas | There is only one performance obligation that includes transport and handling services to the point of delivery. <br>The transaction price is established at the time of sale, including the estimation of variable considerations such as capacity, penalties, extraordinary sales not included in contracts, adjustments for quality or volume claims, and incentives for the purchase of products; which are known days after the transaction. Such variable consideration is recognized to the extent that it is probable that it will not be reversed in a future period. | Revenue is recognized at a point in time when control is transferred to the customer, which occurs when it is delivered at the customer's facilities. Therefore, transportation fees can be included in the price of sale of the product and are considered part of a single performance obligation since transportation is rendered before control is transferred. <br>Revenue initially is measured estimating variables as quality and volume claims, etc. Invoices are usually payable within 30 days. |
| Services | In cases where within the same service order there are transportation and storage services, there could exist more than one performance obligation, depending on the term of the service. <br>When there is a performance obligation, the price is not distributed, but if it is considered that there is more than one performance obligation, the price of the transaction is considered based on the prices established in the service orders and which also include penalties such as quality and volume claims. | Income is recognized over time as the service is rendered. <br>Invoices are usually payable within 22 days. |
| Other products | There is only one performance obligation that includes transportation for delivery to destination. <br>The sale and delivery of the product are made at the same time and because they are FOB, transportation fees are included in the price of sale of the product. <br>The transaction price is established at the time of sale, including the estimation of variable considerations such as capacity, penalties, extraordinary sales not included in contracts, adjustments for quality or volume claims, and incentives for the purchase of products; which are known days after the transaction. | The price of the product is estimated on the date of sale and considers variables such as quality and volume claims, etc. <br>Invoices are usually payable within 30 days. |

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

**B.&nbsp;&nbsp;&nbsp;&nbsp;Accounts receivable in the statement of financial position**

As of December 31, 2025 and 2024, PEMEX had accounts receivable derived from customer contracts in the amounts of Ps. 111,994,478 and Ps. 126,733,175, respectively (see Note 10). As of December 31, 2025 and 2024, customer advances of Ps. 16,048,150 and Ps. 26,494,706, respectively, are recognized under the item accounts and accrued expenses payable. Customer advances recognized in revenue for the years ended December 31, 2025 and 2024 were Ps. 5,351,248 and Ps. 6,199,067, respectively.

**C.&nbsp;&nbsp;&nbsp;&nbsp;Practical expedients**

*i.&nbsp;&nbsp;&nbsp;&nbsp;Significant financial component, less than one year*

PEMEX does not need to adjust the amount committed in consideration for goods and services to account for the effects of a significant financing component, since the transfer and the time of payment of a good or service committed to the customer is less than one year.

*ii.&nbsp;&nbsp;&nbsp;&nbsp;Practical expedient*

PEMEX applied the practical expedient, so disclosure about remaining performance obligations that conclude in less than one year is not needed.

When PEMEX is entitled to consideration for an amount that directly corresponds to the value of the performance that PEMEX has completed, it may recognize an income from ordinary activities for the amount to which it has the right to invoice.

**D.&nbsp;&nbsp;&nbsp;&nbsp;Notable External Events** 

*Armed conflict and related destabilization of world energy markets*

The prices of oil and natural gas remain extremely volatile as a result of ongoing armed conflicts, including the military conflict involving Russia and Ukraine, the conflicts in Gaza and Lebanon and the war involving Iran, Israel, the United States of America and several other countries in the Middle East— as well as disruptions in strategic maritime transport routes, including the Red Sea and the Strait of Hormuz, which are critical corridors for global energy trade. PEMEX's revenues and profitability are heavily dependent on the prices it receives from sales of oil, natural gas and refined products. Oil prices are particularly sensitive to actual and perceived threats to global political stability and to changes in production from OPEC and OPEC+ member states and other oil-producing nations. Destabilization of global oil and gas prices could reduce PEMEX's sales and adversely affect its results and profitability. Oil and gas prices have, on average, decreased and may continue to decrease based on factors beyond PEMEX's control, including geopolitical events.

During 2025, the price of the Mexican crude oil export mix decreased by U.S.$13.08 or 19.6%, from U.S.$66.7 per barrel in 2024 to U.S.$53.62 per barrel in 2025, which was reflected in the decrease in the value of our revenues.

During 2024, the price of the Mexican crude oil export mix decreased by U.S.$0.95 or 1.4%, from U.S.$67.65 per barrel in 2023 to U.S.$66.70 per barrel in 2024, which was reflected in the decrease in the value of PEMEX's revenues.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

On March 4, 2022, the Mexican Government published a decree in the Official Gazette of the Federation establishing a tax incentive pursuant to which PEMEX can recover the difference between the international reference price of gasoline and the price at which gasoline is traded in the domestic market, effective as of December 31, 2025. For the years ended December 31, 2025, 2024 and 2023, this complementary incentive amounted to Ps.0, Ps.0 and Ps.23,421, respectively, which is included as a separate line item in total sales in the Statement of Comprehensive Income (see Note 3-S).

**NOTE 8.&nbsp;&nbsp;&nbsp;&nbsp;FINANCIAL INSTRUMENTS**

**A.&nbsp;&nbsp;&nbsp;&nbsp;Accounting classifications and fair values of financial instruments-**

The following tables present information about PEMEX's carrying amounts and fair values of financial assets and financial liabilities, including their levels in the fair value hierarchy, as of December 31, 2025 and 2024. It does not include fair value information for financial assets and financial liabilities not measured at fair value if the carrying amount is a reasonable approximation of fair value.

Additionally, as of December 31, 2025 and 2024, the disclosure of the fair value for the lease obligations is not required.

Debt is valued and registered at amortized cost and the fair value of debt is estimated using quotes from major market sources which are then adjusted internally using standard market pricing models. As a result of relevant assumptions, the estimated fair value does not necessarily represent the actual terms at which existing transactions could be liquidated or unwound.

The information related to "Cash and cash equivalents", "Customers and other accounts receivable", "Government bonds and other assets", "Debt", "Leases", "Long-term contractual liabilities" and "Derivative financial instruments" is described in the following notes, respectively:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Note 9, Cash and cash equivalents.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Note 10, Customers and other financing and non-financing accounts receivable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Note 14, Government bonds, long-term notes receivable and other assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Note 15, Debt.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Note 16, Leases.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Note 17, Long-term contractual liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Note 18, Derivative financial instruments.

**B.&nbsp;&nbsp;&nbsp;&nbsp;Fair value hierarchy**

PEMEX values the fair value of its financial instruments under standard methodologies commonly applied in the financial markets. PEMEX's related assumptions and inputs therefore fall under the three Levels of the fair value hierarchy for market participant assumptions, as described below.

The fair values determined by Level 1 inputs utilize quoted prices in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs are based on quoted prices for similar assets or liabilities in active markets, and inputs other than quoted prices that are observed for assets or liabilities. Level 3 inputs are unobservable inputs for the assets or liabilities, and include situations where there is little, if any, market activity for the assets or liabilities.

Management uses appropriate valuation techniques based on the available inputs to measure the fair values of PEMEX's applicable financial assets and financial liabilities.

When available, PEMEX measures fair value using Level 1 inputs, because they generally provide the most reliable evidence of fair value.

(1) The impairment of export customers recognized in 2025 and 2024 was mainly in uncollectible export accounts due to the lack of a reasonable expectation of recovery. Indicators that there is no reasonable expectation of recovery include, among others, the fact that the debtor does not suggest a payment plan.

*Methodology to determine the estimation of the impairment of the accounts receivable* 

PEMEX uses a simplified approach in determining the impairment of accounts receivable. Under this approach, a risk analysis is assigned to each customer level, based on historical data used to predict the loss risk, applying a experienced credit judgment. Credit risk rating is defined using qualitative and quantitative factors that are indicative of the risk of default. Exposures within each credit risk rate are segmented by commercial business lines, so the expected credit loss rate is calculated for each segment based on actual credit loss experienced over the past three years. Additionally, PEMEX considers qualitative factors in determining the expected credit loss.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

As of December 31, 2025, the expected percentage of credit loss for accounts receivable was: 7.40% for Industrial Processes and Energy Transformation activities, 8.18% for Corporate activities, 27.50% for Logistics activities, 0.15% for PMI CIM and 0.07% for PMI TRD. Following the dissolution of the subsidiary entities on March 19, 2025, the Logistics

and Corporate activities are included within the Other Operating Subsidiary Companies segment (see Note 6); however,

expected credit loss rates continue to be determined separately for these business lines. As of December 31, 2024, the expected percentage of credit loss for accounts receivable for each Subsidiary Entity and Subsidiary Company was: 4.69% for Pemex Industrial Transformation, 4.94% for Pemex Corporate, 1.64% for Pemex Logistics, 0.13% for PMI CIM and 0.47% for PMI TRD.

The amount of (impairment) of domestic and export customers recognized in the statement of comprehensive income for 2025, 2024 and 2023 was Ps. (12,931,983), Ps. (15,438,558) and Ps. (3,113,324), respectively.

As of December 31, 2025, the Exploration and Extraction segment recognized a net reversal of impairment of Ps. 12,597,956 mainly due to: (i) the positive effect of Ps. 41,071,395, due to lower productive costs mainly in the Cantarell, Tsimin Xux and Ayin-Alux CGUs; (ii) a decrease in the discount rate of Ps. 29,807,328, from 10.86% as of December 31, 2024 to 6.28% as of December 31, 2025; and (iii) a positive tax effect of Ps. 3,640,303 driven by a lower tax base due to the decrease in prices, exchange rate and volume. These effects were partially offset by (i) a decrease in production profiles volume in the barrel of crude oil equivalent generating a negative effect of Ps. 35,165,415, mainly in the Ogarrio Sanchez Magallanes, Antonio J. Bermudez and Burgos CGUs; (ii) a decrease in crude oil prices, generating a

negative effect of Ps. 4,360,188, mainly in the Lakach, Ogarrio, Sánchez Magallanes and Arenque CGUs, and (iii) a negative effect due to an exchange rate of Ps. 22,395,467, from Ps. 20.2683 = U.S.$1.00 as of December 31, 2024 to Ps. 17.9667 = U.S.$1.00 as of December 31, 2025.

As of December 31, 2024 Pemex Exploration and Production recognized a net reversal of impairment of Ps.24,027,347 mainly due to: (i) the positive effect of Ps.246,736,694, due to lower productive costs mainly in the Aceite Terciario del Golfo, Antonio J. Bermúdez, Poza Rica and Arenque CGUs (ii) the positive effect due to an exchange rate of Ps.51,936,270 from Ps.16.9220 = U.S$1.00 as of December 31, 2023 to Ps.20.2683 = U.S$1.00 as of December 31, 2024; and (iii) an increase in crude oil prices and condensate products, generating a positive effect of Ps. 24,921,879 mainly in the Aceite Terciario del Golfo, Lakach, Tamaulipas Constituciones and Tsimin Xux CGUs. These effects were partially offset by (i) an increase in the discount rate of Ps.133,289,611 from de 9.93% in December 31, 2023 to 10.86% in December 31, 2024; (ii) a decrease in production profiles volume in the barrel of crude oil equivalent generating a negative effect of Ps.128,567,201 mainly in the Cantarell, Burgos and Ogarrio Sanchez Magallanes CGUs, and (iii) a negative tax effect of Ps.37,710,685 due to a higher tax base motivated by benefits in production costs, exchange rate and hydrocarbon prices, mainly in the Cantarell, Burgos and Ogarrio Sanchez Magallanes CGUs.

As of December 31, 2023, Pemex Exploration and Production recognized a net impairment of Ps. (2,353,077) mainly due to:(i) the negative effect of Ps.64,145,752 due to increase in cost and expenses mainly in the Aceite Terciario del Golfo, Burgos, Tsimin Xux and Ogarrio Sánchez CGUs, (ii) the negative effect due to an exchange rate of Ps. 47,149,878, from Ps. 19.4143 = U.S.$1.00 as of December 31, 2022, to Ps. 16.9220 = U.S.$1.00 as of December 31, 2023; and (iii) an increase in the discount rate of Ps. 23,731,588, from 9.31% in December 31, 2022 to 9.93% in December 31, 2023. These effects were partially offset by (i) an increase in crude oil prices and condensate products, generating a positive effect of Ps. 73,989,335 mainly in the Cantarell, Tamaulipas Constituciones and Crudo Ligero Marino CGUs; (ii) an increase in production profiles volume in the barrel of crude oil equivalent generating a positive effect of Ps. 45,517,214, mainly in the Antonio J. Bermúdez, Crudo Ligero Marino, Chuc, Ogarrio Sánchez, Ixtal Manik and Tamaulipas Constituciones CGUs; and (iii) a positive tax effect of Ps. 13,167,592, due to a lower tax base motivated by increases in cost and expenses at the Aceite Terciario del Golfo, Burgos and Tsimin Xux CGUs.

The CGUs of Exploration and Extraction are investment projects in productive fields with hydrocarbon reserves associated with proved reserves. These productive hydrocarbon fields contain varying degrees of heating power consisting of a set of wells and are supported by fixed assets associated directly with production, such as pipelines, production facilities, offshore platforms, specialized equipment and machinery.

Each project represents the smallest unit which can concentrate the core revenues, with clear costs and expenses that enable future cash flows (value in use) to be determined.

Exploration and Extraction determines the recoverable amount of fixed assets based on the long-term estimated prices for Exploration and Extraction proved reserves. The recoverable amount on each asset is the value in use.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

To determine the value in use of long-lived assets associated to hydrocarbon extraction, the net present value of reserves is determined based on the following assumptions:

---

For 2025, 2024 and 2023 the total forecast production, calculated with a horizon of 25 years, was 6,915 Million barrels of oil equivalent (Mboe), 6,965 Mboe and 7,082 Mboe per day of crude oil equivalent, respectively.

Exploration and Extraction, in compliance with practices observed in the industry, estimates the recovery value of an asset by determining its value in use, based on cash flows associated with proved reserves after taxes and using a discount rate, also after taxes. Cash flows related to plugging wells provision costs are excluded in this computation of discounted cash flows.

As of December 31, 2025, the Industrial Processes segment recognized net impairment of Ps.(1,115,093) due mainly to a (i) a decrease in the variable margin for certain operating centers of National Refining System although in terms of volume, stabilization in production has been achieved as a result of the Rehabilitation Program applied to processing plants, auxiliary services, and tanks, which was initiated in 2019. The main goal of this program is to guarantee the reliability of operations and maintain the stable and optimal processing level at the refineries, (ii) by the fluctuations of the exchange rate from Ps. 20.2683 = U.S.$1.00 as of December 31, 2024 to Ps. 17.9667 = U.S.$1.00 as of December 31, 2025. These effects were partially offset by the partial start-up of the Coking Plant facilities at the Tula Refinery which will allow for an increase in the higher value production; and (iii) a decrease in the discount rate of CGUs of refined products from 14.75% as of December 31, 2024 to 10.95% as of December 31, 2025.

To determine the value in use of long-lived assets associated with the CGUs of Industrial Processes, the net present value of cash flows was determined based on the following assumptions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.Production-sharing contracts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.Profit-sharing contracts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.License agreements; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.Service contracts.

Certain of the EECs are operated though joint arrangements, for which PEMEX recognizes in its financial statements both the rights to the assets and the obligations for the liabilities, as well as profits and losses relating to the arrangements.

The following table sets forth the balance of Mexican Government local bonds (the "Government Bonds") held by Petróleos Mexicanos valued at amortized cost as of December 31, 2025 and 2024:

---

Petróleos Mexicanos retains the risks, benefits and economic rights of the Government Bonds, which were delivered to a financial institution. Petróleos Mexicanos will continue to collect coupon and principal payments from the securities throughout the term of the transaction. Therefore, Petróleos Mexicanos recognizes these Government Bonds as restricted assets and recognizes short-term debt for the monetization.

**NOTE 15.&nbsp;&nbsp;&nbsp;&nbsp;DEBT**

The Federal Revenue Law applicable to PEMEX as of January 1, 2025, published in the Official Gazette of the Federation on December 19, 2024, authorized Petróleos Mexicanos and its subsidiary entities (which were subsequently dissolved on March 19, 2025) to incur an internal net debt up to Ps.143,403,700 and an external net debt up to U.S.$5,512,700. Following the dissolution, this authorization is exercised solely by Petróleos Mexicanos as successor (see Note 1).

Petróleos Mexicanos can incur additional domestic or external debt, as long as the total amount of net debt does not exceed the ceiling established by the Federal Revenue Law.

During the period from January 1 to December 31, 2025, PEMEX participated in the following financing activities:

• On January 22, 2025, Petróleos Mexicanos issued U.S.$400,000, bearing interest at a floating rate linked to 30-day SOFR plus a margin of 350 basis points due March 2026.

• On August 18, 2025, Petróleos Mexicanos entered into a securities lending transaction with a Luxembourg special purpose vehicle, Eagle Funding LuxCo S.à r.l., acting in respect of its compartment "EFL Compartment I" ("EFL I"). Petróleos Mexicanos received U.S. Treasury Securities (the "Eligible Assets") in exchange for a fee payable to EFL I. Petróleos Mexicanos then entered into a 5-year repurchase transaction with three international banks pursuant to which it sold the Eligible Assets for approximately U.S.$11,354,374 (Ps.213,617,793). Pursuant to the repurchase transaction, Petróleos Mexicanos is required to repurchase the Eligible Assets in 10 semi-annual installments starting in 2026 and ending in 2030, and will receive a corresponding amount of Eligible Assets upon each installment payment, which Petróleos Mexicanos will in turn deliver (or cause the international banks to deliver) to EFL I pursuant to the terms of the securities lending transaction. In addition, Petróleos Mexicanos will pay a price differential to the participating banks semi-annually (until maturity of the repurchase transaction), net of any income such banks receive pursuant to the Eligible Assets. Petróleos Mexicanos does not have control and does not retain substantially all the risks and rewards of the Eligible Assets, accordingly Petróleos Mexicanos will not recognize assets or liabilities from the lending transaction, and will recognize cash received from the repurchase transaction as debt.

**NOTE 16.&nbsp;&nbsp;&nbsp;&nbsp;LEASES**

PEMEX leases plants, transportation and storage equipment, port facilities, buildings, land, catalysts, machinery and equipment. Leases generally run for a period of one to twenty years, in some cases with an option to renew the lease after that date. Some lease payments are renegotiated every five years to reflect that the rent payments are market compliant. Some of the leases provide for additional rental payments that are based on changes in local price indexes. For certain leases, PEMEX has restrictions to enter into a sublease agreement.

**NOTE 17.&nbsp;&nbsp;&nbsp;&nbsp;LONG-TERM CONTRACTUAL LIABILITIES**

During 2025, Petróleos Mexicanos entered into amendment agreements with suppliers and contractors with the purpose of extending the payment terms of certain accrued and accepted commercial obligations during the period, in accordance with the financial scheme authorized by the Board of Directors. As a result of these agreements, the original balances recorded as short-term accounts payable to suppliers generated in 2025, were replaced by new obligations with maturities to eight years, subject to a schedule of quarterly payments of principal and interest. As a result, the nature of the obligation changed from a commercial account payable to a financial liability with terms that differ from those originally agreed with the suppliers.

Additionally, certain suppliers chose to present their accounts receivable to a *Fideicomiso Privado Irrevocable de Administración y Fuente de Pago (*Irrevocable Private Trust for Administration and Source of Payment), resulting in a legal subrogation from the original creditor, without modifying the agreed economic terms in the amendment agreements. In these cases, Petróleos Mexicanos maintains a direct financial obligation to the trust.

Petróleos Mexicanos assessed whether the modifications to the contractual terms resulted in the derecognition of the original liability, considering the extended maturity, the addition of interest on outstanding balances and the scheduled quarterly payments. Based on this assessment, Petróleos Mexicanos concluded that the amendment agreements together with the legal subrogation in applicable cases, resulted in the extinction of the original obligation and the recognition of a new financial liability.

Consequently, Petróleos Mexicanos derecognized the original liabilities and recognized a new financial liability classified as "Long-term contractual liabilities", which was initially measured at fair value. The contractual interest rates of the amendment agreements approximate market rates for instruments with similar terms and credit risk; accordingly, no material gain or loss arose upon initial recognition of the new financial liabilities. The book value of each of the new contractual long-term liabilities is presented below:

---

|:---|:---|:---|:---|:---|
| **Contractual liability** | **Date of Agreement** | **Interest rate spread** | **Balances as of December 31, 2025** | **Balances as of December 31, 2025** |

|  |  |  | Ps. | 193033065 |

---

Accrued interest is determined based on a variable rate equivalent to TIIE plus a margin of 1.80% or 1.85%, as applicable. Accrued interest is recognized as a financial cost in the statement of comprehensive income. During 2025, there were no payments of principal and interest.

Liabilities arising from the amendment agreements are presented separately in the statement of financial position in the "Long-term contractual liabilities" line item as they represent financial obligations distinct from ordinary accounts payable. Cash flows related to the payment of principal and interest of long-term contractual liabilities are presented in the statement of cash flows as financing activities.

Information regarding the liquidity risk associated with these liabilities is disclosed in Note 18; fair value measurement is disclosed in Note 8.

**NOTE 18.&nbsp;&nbsp;&nbsp;&nbsp;DERIVATIVE FINANCIAL INSTRUMENTS**

PEMEX faces market risk caused by the volatility of hydrocarbon prices, exchange rates and interest rates, credit risk associated with investments and financial derivatives, as well as liquidity risk. In order to monitor and manage these risks, PEMEX has approved general provisions relating to financial risk management, which are comprised of policies and guidelines that promote an integrated framework for risk management, regulate the use of Derivative Financial Instruments (DFIs), and guide the development of risk mitigation strategies.

This regulatory framework establishes that DFIs should be used only for the purpose of mitigating financial risk. The use of DFIs for any other purpose must be approved in accordance with PEMEX's current internal regulation. PEMEX has a Financial Risk Working Group (FRWG) which is a specialized working group with decision-making authority on financial risk exposure, financial risk mitigation schemes, and DFIs trading of PEMEX.

Approved DFIs are mainly traded on the Over-the-Counter (OTC) market; however, exchange traded instruments may also be used. In the case of PMI Trading, DFIs are traded on CME-Clearport.

The different types of DFIs that PEMEX trades are described below in the subsections corresponding to each risk type and as related to the applicable trading markets.

One of PEMEX's policies is to contribute to minimizing the impact that unfavorable changes in financial risk factors have on its financial results by promoting an adequate balance between incoming cash flows from operations and outgoing cash flows related to its liabilities.

As part of the regulatory framework for financial risk management, PEMEX has established the eligible counterparties with which it may trade DFIs and other financial instruments.

In addition, certain PMI Subsidiaries have implemented a regulatory framework for risk management with respect to its activities, which consists of policies, guidelines and procedures to manage the market risk associated with its commodity trading activities in accordance with industry best practices, such as: 1) the use of DFIs for financial risk mitigation purposes; 2) the segregation of duties; 3) valuation and monitoring mechanisms, such as the generation of a daily portfolio risk report, value at risk ("VaR") computation; and 4) VaR limits at business unit level and the implementation of stop loss mechanisms.

Given that PEMEX's outstanding DFIs have been entered into for risk mitigation purposes, particularly with economic hedging purposes, there is no need to establish and monitor market risk limits.

For those portfolios with an open market risk exposure, PEMEX's financial risk management regulatory framework establishes the implementation and monitoring of market risk metrics and limits (such as VaR, among others).

PEMEX has also established credit guidelines for DFIs that PEMEX offers to its domestic customers, which include the use of guarantees and credit lines. For exchange traded DFIs PEMEX trades under the margin requirements of the corresponding exchange market, and therefore, does not have internal policies for these DFIs.

Most DFIs held with financial counterparties do not require collateral exchange clauses. Notwithstanding, PEMEX's regulatory framework promotes credit risk mitigation strategies such as collateral exchange.

PEMEX does not have an independent third party to verify compliance with these internal standards; however, PEMEX has internal control procedures that certify compliance with existing policies and guidelines.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*i.&nbsp;&nbsp;&nbsp;&nbsp;Interest rate risk*

PEMEX is exposed to fluctuations in floating interest rate liabilities. PEMEX is exposed to U.S. dollar Secured Overnight Financing Rate (SOFR), to TIIE Mexican peso and TIIE funding rate. As of December 31, 2025, approximately 20.8% of PEMEX's total net debt outstanding (including DFIs) consisted of floating rate debt.

Occasionally, for strategic reasons or in order to offset the expected inflows and outflows, PEMEX has entered into interest rate swaps and options. Through the swap agreements, PEMEX acquires the obligation to make payments based on a fixed or floating interest rate in exchange for receiving payments referenced to a floating or fixed interest rate according to what is assessed as convenient. On the other hand, under the option agreements, PEMEX acquires protection against potential increases in the floating interest rates of some of its liabilities.

During 2024, PEMEX entered into nine interest rate swaps for an accumulated notional amount of U.S.$900 million, through which the fixed coupons associated with a U.S.$1,988 million debt issue maturing in 2028 were converted into floating coupons referenced to SOFR floating interest rates, in order to reduce the financial cost.

During 2025, as a result of Pemex's liability management, an unwind of an interest rate hedging DFI associated with the repurchased bonds was executed, for a notional amount of U.S.$100 million.

As of December 31, 2025, Petróleos Mexicanos was a party to eight interest rate swap agreements denominated in U.S. dollars for an aggregate notional amount of U.S.$800,000 at a weighted average fixed interest rate of 5.35% and a weighted average term of 2.1 years.

Similarly, in order to eliminate the volatility associated with variable interest rates of long-term financing operations, PMI NASA could also execute interest rate swap agreements denominated in U.S. dollars.

As of December 31, 2025, there was no ongoing interest rate DFI of PMI NASA.

Moreover, PEMEX invests in pesos and U.S. dollars in compliance with applicable internal regulations, through portfolios that have different purposes that seek an adequate return subject to risk parameters that reduce the probability of capital losses. The objective of the investments made through these portfolios is to meet PEMEX's obligations payable in pesos and U.S. dollars.

The investments made through PEMEX's portfolios are exposed to domestic and international interest rate risk and credit spread risk derived from government and corporate securities, and inflation risk arising from the relationship between UDIs and pesos. However, these risks are mitigated by established limits on exposure to market risk.

**<u>Reference rates transition</u>**

As a result of the decision made by the Financial Stability Board (FSB), the Interbank Offered Rates (IBORs) were replaced by alternative reference rates, based on risk-free rates obtained from market operations. Therefore, PEMEX has carried out the necessary actions to amend the contracts that were referenced to IBOR benchmark rates in accordance with the applicable regulations.

In line with market practice, PMI Trading's credit agreements include the new language to use the Secured Overnight Funding Rate (SOFR) as their reference rate.

(Figures stated in thousands, except as noted)

Banco de Mexico (the Mexican Central Bank) announced that the 28-day TIIE ceased to be a reference for new contracts as of January 1st, 2025. Similarly, the 91-day and 182-day TIIE ceased to be reference rates for new contracts as of January 1st, 2024.

In response, Petróleos Mexicanos carried out the actions it deemed pertinent and necessary to modify contracts referenced to TIIE rates in line with the modifications announced by Banco de Mexico.

In the event that TIIE ceases to be published, the financial instruments portfolio referenced to these floating rates is composed of debt instruments and DFIs as shown below:

<sup>(1)</sup> Note: Notional amounts with maturity after December 31, 2025.

PEMEX's portfolio also consists of additional debt instruments and DFIs referenced at fixed and float rates, which are not listed in the table above since these instruments will not be impacted by this change.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*ii.&nbsp;&nbsp;&nbsp;&nbsp;Exchange rate risk*

Most of PEMEX's revenues are denominated in U.S. dollars, a significant amount of which is derived from exports of crude oil and petroleum products, which are priced and payable in U.S. dollars. Additionally, PEMEX's revenues from domestic sales of gasoline and diesel net of IEPS Tax, tax duties, incentives, and other related taxes, as well as domestic sales of natural gas and its byproducts, LPG and petrochemicals, are referenced to international U.S. dollar-denominated prices.

PEMEX's expenses related to hydrocarbon duties are calculated based on international U.S. dollar-denominated prices and the cost of hydrocarbon imports that PEMEX acquires for resale in Mexico or use in its facilities are indexed to international U.S. dollar-denominated prices. On the other hand, PEMEX determines the annual amount to be allocated to its capital expenditure and operating expenses as a fixed amount in pesos.

As a result of this cash flow structure, the depreciation of the peso against the U.S. dollar increases PEMEX's financial balance. The appreciation of the peso relative to the U.S. dollar has the opposite effect. PEMEX manages this risk without hedging instruments because the impact of exchange rate fluctuations between the U.S. dollar and the peso on PEMEX's revenues is partially offset by its impact on its obligations.

PEMEX prioritizes debt issuances denominated in U.S. dollars; nonetheless, this is not always achievable, hence non-U.S. dollar denominated debt issued in international currencies is hedged through DFIs to mitigate their exchange rate exposure, either by swapping it into U.S. dollars or through other derivative structures. The rest of the debt is denominated in pesos or in UDIs, and for the debt denominated in UDIs, it has been converted into pesos through DFIs in order to eliminate the inflationary risk exposure.

As a consequence of the above, PEMEX's debt issued in international currencies other than U.S. dollars has exchange rate risk mitigation strategies. PEMEX has selected strategies that further seek to reduce its cost of funding by leaving, in some cases, part of this exchange rate exposure unhedged when assessed as appropriate.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

The underlying currencies of PEMEX's DFIs that mitigate the exchange rate risk are the euro and the Japanese yen against the U.S. dollar and UDIs against the peso.

As of December 31, 2025, and 2024, PEMEX did not enter into any DFIs to mitigate the exchange rate risk, since no debt in currencies other than U.S. dollars or pesos was issued.

Nevertheless, during 2025, as a result of Pemex's liability management, eighteen total unwinds and three partial unwinds of exchange rate risk hedging DFIs associated with the repurchased bonds were carried out for a cumulative notional amount of €3,211.8 million.

During 2023, PEMEX carried out the partial restructure of one and the whole restructure of another cross-currency swap, entering into three similar DFIs, with better financial conditions for PEMEX, having the main objective of reducing the financing cost of its debt. These restructured swaps have the purpose of hedging the exchange rate risk of debt issued by €650,000, with maturity in 2025.

Additionally, during 2023, PEMEX restructured ten cross currency capped swaps that had the purpose of hedging the exchange rate risk of debt issued by €1,250,000, with maturity in 2027. The restructure consisted in entering into ten similar DFIs, with better conditions for PEMEX, having the main objective of reducing the financing cost of its debt.

PEMEX recorded a total foreign exchange gain (loss) of Ps. 195,182,398, Ps. (304,452,236) and Ps. 238,079,042, for the years ended December 31, 2025, 2024 and 2023, respectively. These amounts include the unrealized foreign exchange gain (loss) associated with debt of Ps. 178,825,721, Ps. (261,416,691) and Ps. 208,865,338, for the years ended December 31, 2025, 2024 and 2023, respectively. Unrealized foreign exchange gains and losses do not impact PEMEX's cash flows. The appreciation of the peso during 2025 caused a total net foreign exchange gain because a significant portion of PEMEX's debt, 90.95% (principal only) as of December 31, 2025, is denominated in a currency other than the Mexican peso. Due to the cash flow structure described above, the depreciation of the peso relative to the U.S. dollar does not affect PEMEX's ability to meet U.S. dollar-denominated financial obligations and it improves PEMEX's ability to meet peso-denominated financial obligations. On the other hand, the appreciation of the peso relative to the U.S. dollar may increase PEMEX's peso-denominated debt service costs on a U.S. dollar basis.

Certain of the PMI Subsidiaries face market risks generated by fluctuations in foreign exchange rates. In order to mitigate these risks, the boards of directors of several of these companies have authorized a policy which stipulates that financial assets must be denominated in its functional currency, unless the company owes a duty or expected payment in a currency other than its functional one.

Finally, a significant amount of PMI Trading's income and expenses, including the cost of sales and related sales costs, is derived from the trade of refined products, petrochemicals and gas liquids to PEMEX subsidiaries and third parties, whose prices are determined and are payable in U.S. dollars. PMI Trading's exposure to foreign currency risk results primarily from the need to fund tax payments denominated in domestic currency, as well as from certain related sales costs denominated in domestic currency.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*iii.&nbsp;&nbsp;&nbsp;&nbsp;Hydrocarbon Price Risk* 

PEMEX periodically assesses its revenues and expenditures structure in order to identify the main market risk factors that PEMEX's cash flows are exposed to in connection with international hydrocarbon prices. Based

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

on this assessment, PEMEX monitors its exposure to the most significant risk factors and quantifies their impact on PEMEX's financial balance.

PEMEX's exports and domestic sales are directly or indirectly related to international hydrocarbon prices. Therefore, PEMEX is exposed to fluctuations in these prices. In terms of crude oil and natural gas, part of this risk is transferred to the Mexican Government under PEMEX's current fiscal regime.

PEMEX's exposure to hydrocarbon prices is partly mitigated by natural hedges between its inflows and outflows.

Additionally, PEMEX continuously evaluates the implementation of risk mitigation strategies, including those involving the use of DFIs, taking into consideration their operative and budgetary feasibility.

In 2017, the Board of Directors of Petróleos Mexicanos approved the establishment of an Annual Oil Hedging Program. Since then, PEMEX has implemented hedging strategies to protect its cash flows from falls in the Mexican crude oil basket price from the level that PEMEX asses as adequate, considering the cost-protection ratio.

During the second half of 2022, and the first quarter of 2023, PEMEX entered into a crude oil hedge for the fiscal year 2023 pursuant to which PEMEX hedged 320 thousand barrels per day on average for the period between January 2023 and December 2023, for U.S.$199,943.

During the second half of 2023, and the first semester of 2024, PEMEX entered into a crude oil hedge for the fiscal year 2024, pursuant to which PEMEX hedged 168 thousand barrels per day on average, for the period between December 2023 and December 2024, for U.S.$118,540.

During the fourth quarter of 2024 and the first quarter of 2025, PEMEX entered into a crude oil hedge for the fiscal year 2025, pursuant to which PEMEX hedged 455 thousand barrels per day on average for the period between January 2025 and December 2025, for U.S.$195,404.

As of December 31, 2025, PEMEX does not have any active hydrocarbon price risk hedging DFIs related to the oil hedge.

Additionally, PEMEX cash flows are exposed to crack spread movements as these determine the refining margin.

During 2025, PEMEX implemented its hedging strategy to partially protect its cash flows exposed to diesel crack spread against drops below a level higher than the one established in the Federal Revenue Law for the fiscal year 2025. This is a zero-cost hedging strategy, carried out through swaps which hedged 4,110,000 barrels for the period between July and November 2025.

During the first half of 2025, PEMEX implemented a hedging strategy to partially protect its cash flows exposed to gasoline crack spread against drops below a level higher than the one established in the Federal Revenue Law for the fiscal year 2025. This is a zero-cost hedging strategy, carried out through swaps which hedged 5,310,000 barrels for the period between March and August 2025.

As of December 31, 2025, PEMEX does not have any active hydrocarbon commodity price risk hedging DFIs related to the diesel or gasoline crack spread.

In addition to supplying natural gas, PEMEX can offer DFIs to its domestic customers in order to provide them with support to mitigate the risk associated with the volatility of natural gas prices.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

PMI Trading faces market risk generated by the terms of the purchase and sale of refined products and natural gas liquids, as well as the volatility of oil prices. Accordingly, it frequently enters into DFIs in order to mitigate this risk, thereby reducing the volatility of its financial results.

In accordance with the risk management regulatory framework that PMI Trading has implemented, VaR and the change in profit and loss by portfolio are calculated daily and compared to the maximum applicable limits in order to implement risk mitigation mechanisms as necessary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*iv.&nbsp;&nbsp;&nbsp;&nbsp;Market* risk quantification

The quantification of market risk exposure in PEMEX's financial instruments is presented below, in accordance with the applicable international risk management practices.

<u>Interest rate risk quantification</u>

The quantification of interest rate risk of investment portfolios is carried out by using the one-day horizon historical VaR, with a confidence level of 95%, over a period of one year. The VaR incorporates interest rate and spread risks. In addition, for portfolios in domestic currency, the VaR includes the inflation risk embedded in securities denominated in UDI. For portfolio management purposes, interest rate risk is mitigated by VaR limits.

As of December 31, 2025, the VaRs of PEMEX's investment portfolios were Ps. 0.00 for the Peso Treasury Portfolio, Ps. 0.00 for FOLAPE, and U.S.$0.00 for the U.S. Dollar Treasury Portfolio, since these investment portfolios have no risk position.

Additionally, PEMEX has a portfolio of Mexican Government bonds. It is considered that these securities are not exposed to market risk, unlike the investment portfolios' securities. Therefore, there is no need to calculate a VaR.

In addition to the exposure to interest rate fluctuations of the DFIs in which PEMEX is obligated to make payments referenced to floating rates, PEMEX's DFIs are exposed to Mark-to-Market ("MtM") volatility as a result of changes in the interest rate curves used in their valuation.

Interest rate risk quantification was calculated for DFIs in conjunction with the interest rate risk quantification for the debt portfolio. The following table shows the sensitivity of PEMEX's DFIs and debt portfolio to a parallel shift of 10 basis points (bp) over the zero coupon rate curves. The 10bp parallel shift may be used to estimate in a simple manner the impact for proportional values to this shift and was selected in accordance with market practices for financial risk management.

For the debt portfolio, interest rate risk sensitivity was calculated taking into account both the DFI interbank market yield curves and the PEMEX curves (which were also used to estimate the debt portfolios' fair value). These metrics were calculated solely for informational purposes and are not used for portfolio management purposes because PEMEX does not intend to prepay its debt or terminate its DFIs early. Therefore, there is no interest rate risk arising from fixed rate obligations.

In addition, PEMEX performed a retrospective sensitivity analysis of the impact on its financial statements for the years ended December 31, 2025, 2024 and 2023, in which PEMEX assumed either an increase or decrease of 25 basis points in the floating interest rates of its debt and corresponding hedges.

At December 31, 2025, 2024 and 2023, had market interest rates been 25 basis points higher, with all other variables remaining constant, the net loss for the year ended December 31, 2025, would have been Ps. 488,515 higher, the net loss for the year ended December 31, 2024, would have been Ps. 708,985 higher and the net gain for the year ended December 31, 2023, would have been Ps. 616,468 lower, primarily as a result of an increase in interest expense. Conversely, had market interest rates been 25 basis points lower, the net loss for the year ended December 31, 2025, would have been Ps. 488,515 lower, the net loss for the year ended December 31, 2024, would have been Ps. 708,985 lower and the net gain for the year ended December 31, 2023, would have been Ps. 616,468 higher, primarily as a result of a decrease in interest expense.

<u>Exchange rate risk quantification</u>

The investments of PEMEX's portfolios do not face foreign exchange rate risk because the funds of such portfolios are used to meet obligations in pesos and U.S. dollars.

Currency DFIs are entered into in order to hedge exchange rate risk arising from debt flows in currencies other than pesos and U.S. dollars or inflation risk arising from debt flows in UDIs. However, due to the accounting treatment, net income is exposed to MtM volatility, mainly as a result of changes in the exchange rates used in their valuation.

Exchange rate risk quantification was calculated for DFIs in conjunction with the exchange rate risk quantification for the debt portfolio. The following table shows the sensitivity of PEMEX's DFIs and debt portfolio to an increase of 1% to the exchange rates of currencies against the U.S. dollar. The 1% may be used to estimate in a simple manner the impact for proportional values to this increase and was selected in accordance with market practices for financial risk management.

For the debt portfolio, exchange rate risk sensitivity was calculated taking into account both, interbank market yield curves and the PEMEX curves. In addition, the table shows the one-day horizon historical VaR of the remaining open position, with a confidence level of 95%, over a period of one year. These metrics were calculated solely for informational purposes. Nevertheless, in order to carry out management activities related to its debt portfolio, PEMEX periodically conducts quantitative analyses in order to estimate the exchange rate risk exposure generated by its debt issuances. Based on these analyses, PEMEX has elected to enter into

As shown in the table above, exchange rate risk derived from debt denominated in currencies other than U.S. dollars is almost fully hedged by DFIs. The exchange rate risk exposure to the euro and Japanese yen is a result of the delta of the structures described above (Seagull Options and Calls), and considering the current exchange rate levels, represents a lower funding cost than the hedging strategies carried out through swaps.

In addition, PEMEX performed a retrospective sensitivity analysis of the impact on its financial statements of the years ended December 31, 2025, 2024 and 2023, in which PEMEX assumed either an increase or decrease of 10% in the exchange rate between the U.S. dollar and peso in order to determine the impact on net income and equity as a result of applying these new rates to the monthly balances of assets and liabilities denominated in U.S. dollars.

At December 31, 2025, 2024 and 2023, had the peso depreciated against the U.S. dollar by 10% with other variables remaining constant, the net loss for the year ended December 31, 2025, would have been Ps. 94,511,504 higher, the net loss for the year ended December 31, 2024, would have been Ps. 181,253,630 higher and the net gain for the year ended December 31, 2023, would have been Ps.226,165,912 lower, primarily as a result of an increase in the exchange rate. However, had the peso appreciated against the U.S. dollar by 10%, the net loss for the year ended December 31, 2025, would have been Ps. 94,511,504 lower, the net loss for the year ended December 31, 2024, would have been Ps. 181,253,630 lower and the net gain for the year ended December 31, 2023, would have been Ps.226,165,912 higher, primarily as a result of the decrease in exchange rate.

<u>Hydrocarbon price risk quantification</u>

PEMEX occasionally faces market risk due to open positions arising from the mismatch between the DFI portfolio offered to domestic customers and hedges with international counterparties. As of December 31, 2025, PEMEX's natural gas DFI portfolios had no market risk exposure since all the DFIs in its portfolios expired in 2019.

It should be noted that sensitivity analyses were not carried out for other financial instruments, such as accounts receivable and payable (as defined in the financial reporting standards). Such accounts are cleared in short-term, and therefore market risk is considered to be nonexistent. Most of these accounts are related to hydrocarbon prices.

In accordance with the risk management regulatory framework that PMI Trading has implemented, VaR and the change in profit and loss by portfolio are calculated daily and compared to the maximum applicable limits in order to implement risk mitigation mechanisms as necessary.

PMI Trading's global VaR associated with commodities market risk was U.S.$(4,213) as of December 31, 2025. This VaR was calculated using the historical method with a 95% confidence level, two-year history and a one-day horizon, adjusted by liquidity. The minimum VaR recorded during the year was U.S.$(2,932) (registered on January 1st., 2025) and the maximum VaR recorded during the year was U.S.$(10,218) (registered on March 31st., 2025). As of December 31st., 2024, the global VaR 95% was U.S.$(2,932).

The quantification of crude oil price risk is carried out by using the one-day horizon historical VaR, with a confidence level of 95%, over a period of one year. As of December 31, 2025, this was U.S.$0, since there were no active hydrocarbon price risk hedging DFIs related to the oil hedge in place.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**II.&nbsp;&nbsp;&nbsp;&nbsp;Credit Risk**

When the fair value of a DFI is favorable to PEMEX, PEMEX faces the risk that the counterparty will not be able to meet its obligations. PEMEX monitors its counterparties' creditworthiness and calculates the credit risk exposure for its DFIs. As a risk mitigation strategy, PEMEX only enters into DFIs with major financial institutions with a minimum credit rating of BBB-. These ratings are issued and revised periodically by risk rating agencies. Furthermore, PEMEX seeks to maintain a diversified portfolio of counterparties.

In order to estimate PEMEX's credit risk exposure to each financial counterparty, the potential future exposure is calculated by projecting the risk factors used in the valuation of each DFI in order to estimate the MtM value for different periods, taking into account any credit risk mitigation provisions.

Moreover, PEMEX has entered into various long-term cross-currency swaps agreements, using the following as credit risk mitigants: 1) recouponing clauses (pursuant to which when the MtM exceeds the threshold specified in the confirmation, the MtM is adjusted to zero and notional amount is also adjusted), thereby limiting the PEMEX's exposure to its counterparties referenced to a specific threshold amount, as well as the counterparties' exposure to PEMEX; 2) set-off clauses (under which, in the event of a default by either party, the other party has the option to settle the MtM owed to it through the delivery of bonds issued by the defaulting party).

During 2025, three DFIs structures were entered into with the set-off clause. In addition, recouponing clauses were not triggered in any DFI, and no new DFIs with this feature were entered into.

In addition, during 2024 these recouponing clauses were not triggered in any DFI, and no new DFIs with this feature were entered into. Nonetheless, during 2023, the recouponing clause was triggered in a swap contracted to hedge exposure to foreign exchange risk in euros, which resulted in the prepayment of the fair value and the reset of the swap terms so that its fair value is zero. In addition, as part of the synthetic recouponing carried out that year, two cross currency capped swaps incorporated a recouponing clause as part of their features.

According to IFRS 13 "Fair Value Measurement," the fair value or MtM value of DFIs must reflect the creditworthiness of the parties. Consequently, the fair value of a DFI takes into account the risk that either party may default on its obligation. Due to the above, PEMEX applies the credit value adjustment ("CVA") method to calculate the fair value of its DFIs.

For each DFI, the CVA is calculated by determining the difference between the MtM and the estimated MtM adjusted for credit risk. In determining the credit risk, the CVA method takes into account the current market perception about the credit risk of both counterparties, using the following inputs: a) the MtM projection for

each payment date based on forward yield curves; b) the implied default probability obtained from both, PEMEX and the counterparty's credit default swaps, at each payment date; and c) the default recovery rates of each counterparty.

The current and potential exposures, aggregated by credit rating, are as follows:

PEMEX also faces credit risk derived from its investments. As of December 31, 2025, the position in domestic currency was in Mexican Government bonds in pesos. Given the current credit rating, the default probability in this currency is zero according to the default's frequency matrices from rating agencies, therefore no quantification or disclosure of this exposure is made.

Furthermore, by means of its credit guidelines for DFI operations, PEMEX significantly reduces its credit risk exposure related to the DFIs.

In order to qualify for these DFIs, the PEMEX's customers must be party to a current natural gas supply contract and sign a domestic master derivative agreement.

Additionally, according to the credit guidelines, DFIs with these customers must be initially secured by cash deposits, letters of credit or other collateral provisions, as required. The credit guidelines indicate that PEMEX may offer DFIs with an exemption from collateral requirements up to a certain amount, through a credit line approved by the credit committee, based on an internal financial and credit assessment. Moreover, if the credit line is insufficient to cover each client's exposure, the client is obligated to deposit collateral.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

In accordance with these guidelines, in the event that a client does not meet its payment obligations, DFIs related to this client would be terminated, rights to any available collateral would be exercised and, if the collateral were insufficient to cover the fair value, or in the absence of collateral, natural gas supply would be suspended until the payment is made.

As of December 31, 2025, PEMEX had no DFIs of this type.

PMI Trading's credit risk associated with DFI transactions is mitigated through the use of futures and standardized instruments that are cleared through CME-Clearport.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**III.&nbsp;&nbsp;&nbsp;&nbsp;Liquidity Risk**

PEMEX's main internal source of liquidity comes from its operations. Additionally, through its debt planning and the purchase and sale of U.S. dollars, PEMEX currently preserves a cash balance at a level of liquidity in domestic currency and U.S. dollars that is considered adequate to cover its investment and operating expenses, as well as other payment obligations, such as those related to DFIs.

In addition, as of December 31, 2025, Petróleos Mexicanos has acquired a committed U.S. dollar revolving credit line in order to mitigate liquidity risk. The credit line provides access to U.S.$3,508,000 with an expiration date in November 2026. As of December 31, 2025, this credit line is fully available (see Note 15).

During 2025, PEMEX entered into FX Forwards MXN/U.S.$ in order to preserve an adequate level of liquidity in U.S. dollars. As of December 31, 2025, none of these DFIs were outstanding.

In order to mitigate liquidity risk, during 2025, PEMEX conducted two voluntary synthetic recouponings, which involved the restructuring of five UDI/MXN DFIs. Additionally, in the fourth quarter of 2025, PEMEX entered into four DFI structures, three of which consist of two USD/MXN cross currency swaps and five MXN/USD prepaid forwards each, while the other structure comprises a USD/MXN cross currency swap and two MXN/USD exchange rate options. Furthermore, the restructuring of two MXN/USD prepaid swaps was carried out.

For the same purpose, during 2024 PEMEX entered into one MXN/USD prepaid swap and carried out two voluntary synthetic recouponings which involved the restructuring of five UDI/MXN DFIs. Additionally, during 2023 PEMEX entered into two MXN/USD prepaid swaps, one of which matured during the second quarter of 2025 and also carried out a voluntary synthetic recouponing which involved the restructuring of five UDI/MXN DFIs and six EUR/USD cross currency capped swaps.

Finally, the investment strategies of PEMEX's portfolios are structured by selecting time horizons that consider each currency's cash flow requirements in order to preserve liquidity.

PMI Subsidiaries mitigate their liquidity risk through several mechanisms, the most important of which is its centralized treasury, which provides access to two syndicated credit facilities for up to U.S.$500,000 and U.S.$1,500,000, respectively, and cash surplus capacity in the custody of the centralized structure. In addition, certain PMI Subsidiaries have access to bilateral credit lines from financial institutions for up to U.S.$200,000.

These companies monitor their cash flow on a daily basis and protect their creditworthiness in the financial markets. Liquidity risk is mitigated by monitoring certain financial ratios as set forth in the policies approved by each company's board of directors.

The following tables show the cash flow maturities as well as the fair value of PEMEX's debt and DFI portfolios as of December 31, 2025, and 2024. It should be noted that:

***<u>B</u>.&nbsp;&nbsp;&nbsp;&nbsp;<u>Fair value of derivative financial instruments</u>***

PEMEX periodically evaluates its exposure to international hydrocarbon prices, interest rates and foreign currencies and uses derivative instruments as a mitigation mechanism when potential sources of market risk are identified.

PEMEX monitors the fair value of its DFI portfolio on a periodic basis. The fair value represents the price at which one party would assume the rights and obligations of the other and is calculated for DFIs through models commonly used in the international financial markets, based on inputs obtained from major market information systems and price providers. Therefore, PEMEX does not have an independent third party to value its DFIs.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

PEMEX calculates the fair value of its DFIs through the tools developed by its market information providers, and through valuation models implemented in software packages used to integrate all of PEMEX´s business areas and accounting, such as SAP (System Applications Products).

PEMEX's DFI portfolio is composed primarily of swaps, for which fair value is estimated by projecting future cash flows and discounting them with the corresponding market discount factor; for the projection of variable flows, the prices of future contracts of each of the references corresponding to these trades are used.

For currency and interest rate options this is done through the Black and Scholes model, which uses as inputs the prices of the underlying futures, the reference prices agreed in the contracted instruments, the market risk-free rates and the implied volatilities of the instruments traded in the markets. In the case of crude oil options, the Levy Model for Asian options is used, which is based on the Black and Scholes Model, with the difference that this model weights the prices of the futures involved during the hedging period and contemplates a volatility adjustment, based on the terms of the corresponding futures.

According to IFRS 13 "Fair Value Measurement", the MtM value of DFIs must reflect the creditworthiness of the parties. Consequently, the fair value of a DFI takes into account the risk that either party may default on its obligation, considering the counterparties' probability of default. Due to the above, PEMEX applies the credit value adjustment ("CVA") method to calculate the fair value of its DFIs.

For each DFI, the CVA is calculated by determining the difference between the MtM and the estimated MtM adjusted for credit risk. In determining the credit risk, the CVA method takes into account the current market perception about the credit risk of both counterparties, using the following inputs: a) the MtM projection for each payment date based on forward yield curves; b) the implied default probability obtained from both, PEMEX and the counterparty's credit default swaps, at each payment date; and c) the default recovery rates of each counterparty.

Given that PEMEX's hedges are cash flow hedges, their effectiveness is preserved regardless of variations in the underlying assets or reference variables since, over time, asset flows are offset by liabilities flows. Therefore, and in addition to the fact that these hedges are established for accounting purposes as trading instruments, it is not considered necessary to measure the hedge's effectiveness or to monitor them.

PEMEX's assumptions and inputs considered in the calculation of the fair value of its DFIs fall under Level 2 of the fair value hierarchy for market participant assumptions.

<u>Embedded derivatives</u>

In accordance with established accounting policies, PEMEX has analyzed the different contracts (financial and non-financial) that PEMEX has entered into and has determined that according to the terms thereof none of these agreements meet the criteria to be classified as embedded derivatives. Accordingly, as of December 31, 2025 and 2024, PEMEX did not recognize any embedded derivatives (foreign currency or index) in the financial and non-financial contracts.

As of December 31, 2023, PEMEX had recognized a favorable implicit forward for Ps. 194,194, contained in an FX Single Cross Currency Swap contract, which expired in February 2024.

<u>Accounting treatment</u>

PEMEX enters into derivatives transactions with the sole purpose of hedging financial risks related to its operations, firm commitments, planned transactions and assets and liabilities recorded on its statement of financial position. Nonetheless, some of these transactions do not qualify for hedge accounting treatment because they do not meet the requirements of the accounting standards for designation as hedges. They are therefore recorded in the financial statements as instruments entered into for trading purposes, despite the fact that their cash flows are offset by the

cash flows of the positions (assets or liabilities) to which they relate. As a result, the changes in their fair value are recognized in the "Derivative financial instruments income (cost), net" line item in the consolidated statement of comprehensive income.

As of December 31, 2025, and 2024, the net fair value of PEMEX's DFIs, including both DFIs that have not reached maturity and those that have reached maturity but have not been settled, recognized in the consolidated statement of financial position, was Ps. (63,571,865) and Ps. (99,768,509), respectively. As of December 31, 2025, and 2024, PEMEX did not have any DFIs designated as hedges for accounting purposes.

All of PEMEX's DFIs are treated, for accounting purposes, as instruments entered into for trading purposes, therefore any change in their fair value, caused by any act or event, impacts directly in the "Derivative financial instruments income (cost), net" line item in the consolidated statement of comprehensive income.

The following table shows the fair values and notional amounts of PEMEX's DFIs, including those with an open position and those that have matured but that have not been settled, which were designated as non-hedges for accounting purposes and entered into for trading purposes as of December 31, 2025 and 2024. It should be noted that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• DFIs' fair value includes CVA and is calculated based on market quotes obtained from market sources such as Bloomberg, *Proveedor Integral de Precios, S.A. de C.V*., among others.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Fair value is calculated internally, either by discounting cash flows with the corresponding zero-coupon yield curve, in the original currency, or through other standard methodologies commonly used in the financial markets for certain specific instruments.

The fair value of the Futures and the Petroleum Products Swaps was recognized as "Cash and cash equivalents" in the statement of financial position because PEMEX considered these financial assets to be fully liquid.

The exchange rate for U.S. dollars as of December 31, 2025, and 2024, was Ps. 17.9667 and Ps. 20.2683 per U.S. dollar, respectively. The exchange rate for euros as of December 31, 2025, and 2024, was Ps. 21.0974 and Ps. 20.9868 per euro, respectively.

For the years ended December 31, 2025, 2024 and 2023, PEMEX recognized a net (loss) gain of Ps. 21,587,903, Ps. (27,594,230), and Ps. 672,226 respectively, in the "Derivative financial instruments income (cost), net" line item with respect to DFIs treated as instruments entered into for trading purposes (the gain as of December 31, 2023, includes the gain generated by the embedded derivative and the loss as of December 31, 2024, includes the loss from the cancellation of the embedded derivative).

**NOTE 19.&nbsp;&nbsp;&nbsp;&nbsp;EMPLOYEE BENEFITS** 

Until December 31, 2015, PEMEX only had defined benefit pension plans for the retirement of its employees, to which only PEMEX contribute. Benefits under these plans are based on an employee's salary and years of service completed at retirement. As of January 1, 2016, PEMEX also has a defined contribution pension plan, in which both PEMEX and the employee contribute to an employee's individual account.

Benefits under the defined benefit plan are mainly based on the years of service completed by the employee, and their remuneration at the date of retirement. The obligations and costs of these plans are recognized based on an actuarial valuation prepared by independent experts. Within the regulatory framework of plan assets, there are no minimum funding requirements. PEMEX has established additional plans to cover post-employment benefits, which are based on actuarial studies prepared by independent experts and which include disability, post-mortem pension and the death of retired employees, as well as medical services for retired employees and beneficiaries.

For the defined benefit plan, PEMEX funded its employees benefits through Mexican trusts, the resources of which come from the retirement line item of PEMEX's annual budget (an operating expense), or any other line item that substitutes or relates to this line item, or that is associated with the same line item and the interests, dividends or capital gains obtained from the investments of the trusts.

On March 19, 2025, pursuant to the 2025 Petróleos Mexicanos Law, the dissolution of Pemex Exploration and Production, Pemex Industrial Transformation and Pemex Logistics took effect. All of the assets, liabilities, rights and obligations of the subsidiary entities, including all labor liabilities, were assumed by, and transferred to Petróleos Mexicanos, which became the successor of the subsidiary entities as a matter of Mexican Law (Note 1). Accordingly, the figures reported in this note include the labor liabilities of the business segments (see Note 6).

<sup>(1)</sup> The amount of actuarial losses corresponding to retirement and post-employment benefits recognized in other comprehensive income net for Ps.(173,640,083) generated in the period from January to December 2025 correspond to the decrease in the discount rate from 11.28% in 2024 to 9.95% in 2025 as well as the changes in obligations for movements in the population, age, seniority, salary, pensions and benefits. In 2024, as a result of the review of actuarial assumptions, the assumptions related to family composition and the type of pension arising from the death of retirees, salary increases and promotions, as well as the probability of retirement of active personnel, were updated. The impact of these changes was considered in the final figures.

<sup>(1)</sup> The concepts come from the valuation of PMI´s liabilities.

The Labor Fund reduction was due to budgetary requirements derived from the need to meet a financial balance goal in cash flow. In this sense, during 2020 PEMEX's administration implemented a strategy and the contributions to the Fund are scheduled and executed taking into account the initial balance plus the cost of payrolls and retirements for the year, maintaining a minimum operating balance without the operational continuity risk or payment to personnel.

Derived from the Federal Government Contribution due to the Modification of the Pension Plan of PEMEX, from January to December, 2025, PEMEX contributed Ps. 17,398,280 in interest.

From January 1 to December 31, 2025, interest generated by the total of Government Bonds amounted Ps. 1,759,219 of which Petróleos Mexicanos received the payment of Ps. 1,819,299 (see Note 14).

Expected payments for fiscal year 2025 are Ps. 98,510,148.

As of December 31, 2025 and 2024, the amounts and types of plan assets are as follows:

<sup>(1)</sup> The variations in financial assumptions are due to the decrease in the discount rate from 11.28% in 2024 to 9.95% in 2025.

<sup>(2)</sup> The main factor that influenced the actuarial loss due to changes in demographic assumptions in 2025 was primarily the update of the mortality table for retirees. In 2024, derived from the review of the actuarial assumptions, the assumptions of family composition and type of pension derived from the death of retirees, the salary increase and promotions, as well as the probability of retirement of active personnel were updated, the impact of which was considered in the final figures.

<sup>(3)</sup> Changes in assumptions for experience depend on factors that may not remain constant year to year, including changes in population that differ from expectations. The factors that influenced results for 2025 were an increase in salaries, departures and inflows of personnel.

The effects on the Defined Benefits Liability upon retirement and post-employment at the end of the period are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The effect of an increase or decrease of one percentage point in the discount rate is (9.74)% and 11.78%, respectively, in defined benefit obligations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The effect of an increase or decrease of one percentage point in the inflation rate is 7.49% and (6.51)%, respectively, in defined benefit obligations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The effect of an increase or decrease of one percentage point in the wage is 1.01% and (0.91)%, respectively, in defined benefit obligations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The effect of an increase or decrease of one percentage point in medical services is 2.17% and (1.75)%, respectively, in defined benefit obligations.

The effects previously mentioned were determined using the projected unit credit method which was the same method used in the prior valuation.

Assumptions regarding future mortality are based on EMSSA2009 to Unique Circular of the *Comisión Nacional de Seguros y Fianzas* (National Commission of Insurance and Bonds) and include improvements. For the December valuation, the mortality table for retired personnel was updated using an actuarial proposal based PEMEX's experience . The mortality table for the incapacitated personnel is the EMSSInc-IMSS2012 and for the disabled personnel the EMSSInv-IMSS2012.

PEMEX's plan assets is held in the FOLAPE trusts, which are managed by *BBVA México, S.A., Institución de Banca Múltiple, Grupo Financiero BBVA México* and a technical committee for each trust that is comprised of personnel from Petróleos Mexicanos and the trusts. As of December 31, 2025, FOLAPE has a balance of Ps. 2,450,419, while the remaining Ps. 2,299,934 belong to affiliate companies that are in charge of managing their own funds.

As of December 31, 2025 and 2024, the principal actuarial assumptions used in determining the defined benefit obligation for the plans are as follows:

---

| | | |
|:---|:---|:---|
| | **December 31,** | **December 31,** |
| | **2025** | **2024** |
| Rate of increase in salaries | 5.20% | 5.20% |
| Rate of increase in pensions | 4.00% | 4.00% |
| Rate of increase in post-mortem pensions | 0.00% | 0.00% |
| Rate of increase in medical services | 7.65% | 7.65% |
| Inflation assumption | 4.00% | 4.00% |
| Rate of increase in basic basket for active personnel | 5.00% | 5.00% |
| Rate of increase in basic basket for retired personnel | 4.00% | 4.00% |
| Rate of increase in gas and gasoline | 4.00% | 4.00% |
| Discount and return on plan assets rate <sup>(1)</sup> | 9.95% | 11.28% |
| Average length of obligation (years) | 11.40 | 10.91 |

---

<sup>(1)</sup> In accordance with IAS 19, the discount rate was determined using as a reference the interest rates observed in Mexican Government bonds, based on the Fixed Rate bonds of the Federal Government ("Bonos M") and the "Cetes", as well as the flow of expected payments to cover the contingent obligations. As a consequence of the change in the yields of the financial instruments mentioned above at the end of the year, the discount rate decreased compared to the end of 2024.

*Other long-term benefits* 

PEMEX has established other long-term benefit plans for their employees, to which employees do not contribute, which correspond to the seniority premiums payable for disability, death and survivor benefits (payable to the widow and beneficiaries of worker), medical service, gas and basic basket for beneficiaries. Benefits under these plans are based on an employee's salary and years of service completed at separation date. Obligations and costs of such plans are recorded in accordance with actuarial valuations performed by independent actuaries.

The expected long-term benefit payments for 2025 amount to Ps. 484,258.

The principal actuarial assumptions used in determining the defined benefit obligation for the plans are:

• The effect of an increase or decrease of one percentage point in the discount rate is (11.38)% and 14.37%, respectively, in defined benefit obligations.

• The effect of an increase or decrease of one percentage point in the inflation is 0.00% and 0.00%, respectively, in defined benefit obligations.

• The effect of an increase or decrease of one percentage point in the wage is 3.38% and (3.08)%, respectively in defined benefit obligations.

• The effect of an increase or decrease of one percentage point in medical services is 6.34% and (4.66)%, respectively, in defined benefit obligations.

*Provision for plugging of wells* 

PEMEX records a provision at present value for the future plugging cost of an oil production facility or pipeline at the time that it is built.

The plugging provision represents the present value of plugging costs related to oil and gas properties. These provisions have been created based on internal estimates of PEMEX. PEMEX has made certain assumptions based on the current economic environment that PEMEX believes provide a reasonable basis on which to estimate the future liability. These estimates are reviewed regularly to take into account any material changes in the assumptions. However, actual plugging

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

costs in the long run will depend on future market prices for the necessary plugging work, which reflect market conditions at the time the work is being performed.

The calculation of this provision considers the year-end exchange rate, the projected inflation rate for the United States, interpolated discount rates based on the maturity date of long-term debt instruments in U.S. markets, as well as unit costs obtained from current contracts as of the valuation date, the current status of PEMEX's wells and the limit of proved and developed reserves as of January 1, 2024.

As of December 31, 2025, 2024 and 2023, the provision increased due to effects from updates in the reserve limits, adjustments to the discount rate and applications to the reserve. This includes the effect of the discount rate over time of Ps. 7,816,800, Ps. 9,126,600 and Ps. 4,638,600 for 2025, 2024 and 2023, respectively. The discount rate ranges used during 2025, 2024 and 2023 were from 6.720% to 8.210%, 9.090% to 10.390% and 9.510% to 10.050% for U.S. dollar denominated assets, respectively.

Moreover, the time of plugging depends on when the fields cease to have economically viable production rates, which, in turn, depends on the inherently uncertain future prices of oil and gas. Well plugging of works will be carried out as follows:

*Provision for environmental costs* 

PEMEX is subject to the provisions of the *Ley General del Equilibrio Ecológico y la Protección al Ambiente* (General Law on Ecological Equilibrium and Environmental Protection). To comply with this law, environmental audits of PEMEX's larger operating, storage and transportation facilities have been or are being conducted. Following the completion of such audits, PEMEX has signed various agreements to implement environmental remediation and improve environmental plans. Such plans will be sent to the *Agencia Nacional de Seguridad Industrial y de Protección al Medio Ambiente del Sector Hidrocarburos* (National Agency for Industrial Safety and Environmental Protection of the Hydrocarbons Sector or "ASEA"). The period of execution of these works is not defined, as they are subject to the budgets that may be granted to PEMEX.

The *Ley de Ingresos sobre Hidrocarburos* ("Hydrocarbons Revenue Law") was published in the Official Gazette of the Federation on August 11, 2014, and came into effect, on January 1, 2015. The Hydrocarbons Revenue Law sets forth the fiscal regime for Petróleos Mexicanos applicable to the assignments and the contracts that were established on such date. Likewise, every year the Federal Revenue Law is published in the Official Gazette of the Federation and includes specific regulations for Petróleos Mexicanos and the former Subsidiary Entities.

On November 1, 2024, the Energy Reform Decree took effect and transformed the legal regime of Petróleos Mexicanos from an *empresa productiva del Estado* (productive state-owned company) to an *empresa pública del Estad*o (state-owned public company).

The Energy Reform Decree included *artículos transitorios* (transitional provisions) requiring the Mexican Congress to

adjust, amend or otherwise modify any relevant legislation required to give effect to the Energy Reform Decree within 180

calendar days. On March 18, 2025, the Secondary Legislation was published in the Official Gazette of the Federation, following its approval by Congress and enactment by President Claudia Sheinbaum Pardo.

Pursuant to the Energy Reform Decree, Petróleos Mexicanos is no longer subject to income tax as of November 1, 2024 (and, prior to their dissolution, the former subsidiary entities were also exempt)..

Separately, on December 19, 2024, the *Ley de Ingresos de la Federación para el Ejercicio Fiscal de 2025 (*2025 Federal Revenue Law) was published in the Official Gazette of the Federation. The 2025 Federal Revenue Law introduces changes to the fiscal regime applicable to Petróleos Mexicanos aimed at simplifying its fiscal framework and reducing the number of taxes and duties to which it is subject. As of January 1, 2025, the Mexican Government has consolidated the *Derecho de Utilidad Compartida* (Profit-Sharing Duty), the *Derecho de Extracción de Hidrocarburos* (Hydrocarbon Extraction Duty) and the *Derecho de Exploración de Hidrocarburos* (Hydrocarbon Exploration Hydrocarbons Duty), into a single obligation requiring only provisional and annual payments by Petróleos Mexicanos under a newly created *Derecho Petrolero para el Bienestar* (Welfare Oil Duty), which is set at a general rate of 30% on oil and fuel production and 11.63% for non-associated gas. Additionally, Petróleos Mexicanos is no longer subject to income taxes. As a result, on March 18, 2025, the Hydrocarbons Revenue Law was amended to incorporate the Welfare Oil Duty.

*Tax regime applicable to Assignments* 

***A. Derecho Petrolero para el Bienestar (Welfare Oil Duty) (Effective as of January 1, 2025).***

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

This duty is determined by applying, to the value of the hydrocarbons extracted during the relevant fiscal year including self-consumption, as well as losses resulting from spills or flaring of such products without any deductions, a general rate of 30.00% for crude oil and fuel production, and 11.63% for non-associated gas and condensates.

For fiscal year 2025, a total Welfare Oil Duty liability of Ps. 194,573,038 was incurred, which was fully credited against monthly provisional payments in the amount of Ps. 194,574,269.

***B.&nbsp;&nbsp;&nbsp;&nbsp;Impuesto por la actividad de Exploración y Extracción de Hidrocarburos (Exploration and Extraction Hydrocarbons Duty).***

The assignments granted by the Mexican Government create a tax on the exploration and extraction activities carried out in the corresponding area. The monthly tax paid during the exploration phase and until the extraction phase begins is Ps.2,374.84 pesos per square kilometer. During the extraction phase of a project, a monthly tax of Ps.9,499.53 pesos per square kilometer is payable until the relevant contract for exploration and extraction or assignment is terminated.

During 2025 and 2024, the incurred tax was Ps. 6,101,878 and Ps. 5,660,511 respectively, which are included in the cost of sales line item.

**Tax Regime applicable to contracts:** 

The fiscal regime applicable to exploration and extraction contracts (contratos) under Title III of the Hydrocarbons Revenue Law, as amended on March 18, 2025, was not affected by this consolidation and remains in effect. Accordingly, the duties and payments described below continue to apply to contracts held by Petróleos Mexicanos.

As of January 1, 2015, the tax regime applicable to Petróleos Mexicanos for contracts is set forth in the Hydrocarbons Revenue Law which regulates, among other things, the fiscal terms applicable to the exploration and extraction contracts (license, profit sharing contracts, production sharing and services) and sets duties and other taxes paid to the Mexican Government.

The Hydrocarbons Revenue Law also establishes the following duties applicable to PEMEX in connection with assignments granted to it by the Mexican Government:

• ***Cuota Contractual para la Fase Exploratoria (Exploration Phase Contractual Fee)***

During the exploration phase of an exploration and extraction contract, the Mexican Government is entitled to collect a monthly payment of 1,820.72 pesos per square kilometer of non-producing areas. After 60 months, this fee increases to 4,353.94 pesos per square kilometer for each additional month that the area is not producing. The fee amount will be updated on an annual basis in accordance with the national consumer price index.

*•* ***Regalías (Royalties)***

Royalty payments to the Mexican Government are determined based on the "contractual value" of the relevant hydrocarbons, which is based on a variety of factors, including the type of underlying hydrocarbons (e.g., crude oil, associated natural gas, non-associated natural gas or condensates), the volume of production and the market price. Royalties are payable in connection with licensing contracts, production-sharing contracts and profit-sharing contracts.

*•* ***Pago del Valor Contractual (Contractual Value Payment)***

Licensing contracts require a payment to the Mexican Government calculated as a percentage of the "contractual value" of the hydrocarbons produced, as determined by the SHCP on a contract-by-contract basis.

(Figures stated in thousands, except as noted)

*•* ***Porcentaje a la Utilidad Operativa (Operating Profit Payment)***

Production-sharing contracts and profit-sharing contracts require a payment equivalent to a specified percentage of operating profits. In the case of production-sharing contracts, this payment shall be made in-kind through delivery of the hydrocarbons produced. In the case of profit-sharing contracts, this payment shall be made in cash.

*•* ***Bono a la Firma (Signing Bonus)***

Upon execution of a licensing contract, a signing bonus is to be paid to the Mexican Government in an amount specified by the SHCP in the relevant bidding terms and conditions or in the contracts resulting from a migration.

*•* ***Impuesto por la actividad de Exploración y Extracción de Hidrocarburos (Hydrocarbons Exploration and Extraction Activities Tax)***

Contracts for exploration and extraction granted by the Mexican Government will include a specified tax on the exploration and extraction activities carried out in the relevant area. The monthly tax paid during the exploration phase and until the extraction phase begins is 2,374.84 pesos per square kilometer. During the extraction phase of a project, a monthly tax of 9,499.53 pesos per square kilometer is payable until the relevant contract for exploration and extraction or assignment is terminated. During 2025 and 2024 the incurred tax amounted to Ps. 237,153 and Ps. 226,854, respectively.

*Tax regime applicable to Assignments (Effective until December 31, 2024)*

The tax regime applicable to the exploration and production for the assignments granted to PEMEX by the Mexican Government includes the following taxes and duties:

**A.&nbsp;&nbsp;&nbsp;&nbsp;Derecho por la Utilidad Compartida "DUC" (Profit-sharing Duty).** 

As of January 1, 2015, Pemex Exploration and Production was obligated to pay a Profit-sharing Duty.

During 2024, the applicable rate of this duty was 30%. The computation of this duty is based on the excess of the value of hydrocarbons produced during the fiscal year (including self-consumption, shrinkage and burning), minus certain permitted deductions by the Hydrocarbons Revenue Law, including part of the investments and some costs, expenses and duties.

During 2024, this duty was Ps. 188,032,962 from annual payments presented on March 31, 2025 paid as follows: Ps. 124,178,852, of the corresponding Profit-sharing duty for the months of January, May, June and July 2024 in the amount of Ps. 63,122,712 resulting in a balance of Ps. 731,398 as of December 31, 2024.

Of the aforementioned decrees issued by the Federal Government, the first was published on February 13, 2024, in the Official Gazette of the Federation. It granted a tax benefit to PEMEX consisting of a tax credit equivalent to 100% of the Profit-Sharing Duty corresponding to the months of October, November, and December 2023, as well as January 2024.

The second decree was published on August 23, 2024, in the Official Gazette of the Federation. It granted a tax benefit to PEMEX consisting of a tax credit equivalent to 100% of the Profit-Sharing Duty corresponding to the months of May, June, and July 2024.

During fiscal year 2024, DUC payments for the months of May and June were deferred in accordance with the decrees granting tax benefits, published in the Official Gazette of the Federation on June 25, and On July 25, 2024, the August payment was also deferred in accordance with the decrees granting tax benefits, published in the Official Gazette of the Federation on September 25 and October 30, 2024. Finally, the month of October was deferred in accordance with the decree granting tax benefits, published in the Official Gazette of the Federation on November 22, 2024.

Duties and income tax paid as of 2024 and 2023 were Ps.109,402,970 and Ps.234,982,338, respectively.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

The accounting result differs from the tax result mainly due to differences in depreciation, non-deductible expenses and others. Such differences generate a deferred DUC.

Total DUC and other as of 2024 and 2023 are integrated as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **2024** | **2024** | **2023** | **2023** |

| **Total DUC** | **Ps.** | **127499009** | **Ps.** | **214075924** |

The principal factors generating the deferred DUC are the following:

| **Net, deferred DUC asset** | **Ps.** | **2588760** |

---

Deferred DUC not recognized in 2023 amount to Ps. 314,346,132, and resulted from costs, expenses and capital expenditures that will not be recoverable, mainly for on-shore and in Chicontepec deep and shallow waters.

As a result of the changes to Petróleos Mexicanos implemented through the Energy Reform Decree on October 31, 2024 and the amendments introduced by the 2025 Federal Revenue Law, the calculation, recording, recognition and disclosure of the deferred DUC was suspended for balances of assets (liabilities) presentation for deferred profit-sharing duty by Assignments.

The remaining costs, expenses and capital expenditures beginning January 1, 2015 can be balanced to the immediate following years, without them expiring.

The expected expense for DUC in 2024 and 2023 was different from that which would result from applying the 40% rate to the tax base, respectively, as a result of the line items mentioned in the tables below.

***B.&nbsp;&nbsp;&nbsp;&nbsp;Derecho de Extracción de Hidrocarburos (Hydrocarbons Extraction Duty).***

For the determination of the rates applicable to the calculation of this duty, SHCP considered the effects of variations in the U.S. producer price index, or another alternative index, when it determines the rate to be published in the Official Gazette of the Federation. This duty was calculated using a rate based on a formula applicable to each type of hydrocarbon (crude oil, associated natural gas, non-associated natural gas and condensates), the volume of production and utilizing the relevant market price for hydrocarbons in U.S. Dollars.

During 2024, Pemex Exploration and Production incurred a Ps.61,062,729 balance with the corresponding hydrocarbon extraction duty for the months of January, June and July 2024 in the amount of Ps.15,782,932 and the difference of Ps.45,279,797 was included in the cost of sales line item.

The before mentioned decrees were issued on February 13, 2024 and August 24, 2024, respectively by the Mexican Government and issued the Official Gazette of the Federation, suspending the collection of the Hydrocarbons Extraction Duty for the months of October, November, December 2023, January 2024 and May, June and July 2024, respectively.

On July 25, 2024 and September 25, 2024, extraction duty payments for the months from June and August, respectively, were deferred published in the Official Gazette of the Federation.

***C.&nbsp;&nbsp;&nbsp;&nbsp;Derecho de Exploración de Hidrocarburos (Exploration Hydrocarbons Duty).***

Pemex Exploration and Production as "assignee" must make monthly payments for this duty. The rates for 2024 were 1,741.65 pesos per square kilometer of non-producing areas. After 60 months, this tax increases to 4,164.86 pesos per square kilometer for each additional month that the area is not producing. These amounts will be updated on an annual basis in accordance with the national consumer price index.

During 2024, Pemex Exploration and Production incurred Ps. 2,437,425 and which are included in the cost of sales line item.

Petróleos Mexicanos collects the fee on behalf of the Mexican Government. The applicable fees for 2025 are Ps.6.46 per liter of gasoline with an octane rating lower than 91; Ps. 5.45 per liter of gasoline with an octane rating greater than or equal to 91 and Ps.7.09 per liter of diesel. The amount of the fee will depend on the class of fuel. The fee is fixed yearly and adjusted on a weekly basis by the SHCP. The fees apply to sales in Mexico and imports.

***B.*&nbsp;&nbsp;&nbsp;&nbsp;*Value-Added Tax* ("VAT")**

For VAT purposes, final monthly payments are determined based on PEMEX's cash flow, in accordance with the provisions of the Value Added Tax Law, applicable to payers of this tax. The general rate to be applied is 16%. Certain activities with incentives will have the rate of 0%.

Beginning on January 1, 2019, a new Decree of fiscal incentives began to apply to the northern border region, which consisted of a credit equivalent to 50% of the general rate, applicable directly at the time of the sale or service. This incentive is applicable in six states in the northern border region and includes 43 municipalities in those states.

Petróleos Mexicanos and its former Subsidiary Entities apply this tax benefit to the operations they carry out within the municipalities of the States included in the Decree.

VAT is applied to the sale of goods, the rendering of services, the granting of the temporary use of goods in the national territory and the importation of goods and services to the national territory. VAT taxpayers transfer VAT to their customers and are entitled to credit the VAT paid to their suppliers and on their imports.

During 2024, the collection of the VAT for the month of August 2024 was deferred to October the 20%, and November and December 2024, the 40% in each month, in accordance with the decree of tax benefits published on September 17, 2024 in the Official Gazette of the Federation.

**Income tax is described below:** 

***C.&nbsp;&nbsp;&nbsp;&nbsp;Income Tax***

Pursuant to the Energy Reform Decree, approved by Congress on October 17, 2024 and published on October 31, 2024,

and as further reflected in the 2025 Federal Revenue Law, Petróleos Mexicanos is no longer subject to income tax as of November 1, 2024 (and, prior to their dissolution, the former subsidiary entities were also exempt).

The Energy Reform Decree, which took effect on November 1, 2024, transformed the legal regime, of Petróleos Mexicanos and required the Mexican Congress to adopt implementing legislation within 180 calendar days. The Secondary Legislation was approved by Congress on March 12, 2025, signed into law by the President, and published in the Official Gazette of the Federation on March 18, 2025.

All of our subsidiary companies are subject to the Income Tax Law, which is calculated by applying a rate of 30% to the tax result. The tax result is determined as follows: taxable income is obtained by reducing the total accrued income earned during the fiscal year by the authorized deductions provided in Title II. The tax losses from prior years pending application shall, where applicable, be applied against the taxable income for the year.

Accounting result differs from taxable income primarily due to the effects of inflation and differences between depreciation and other non-deductible expenses.

For the years ended 2025 and 2024, Petróleos Mexicanos and its Subsidiary Companies incurred the following income tax expense (benefit):

***D.&nbsp;&nbsp;&nbsp;&nbsp;Accumulated other comprehensive income (loss)***

As a result of the discount rate analysis related to employee benefits liability, for the periods ended December 31, 2025 and 2024 PEMEX recognized net actuarial (loss) and gains and in other comprehensive results, net of deferred income tax for Ps. (173,642,194) and Ps.203,171,826, respectively, which included net of deferred income tax for 2024 of Ps.8,207,274, related to retirement and post-employment benefits. The variation related to retirement and post-employment benefits was the result of a decrease in the discount and return on plan assets rates from 11.28% as of December 31, 2024 to 9.95% as of December 31, 2025.

***E.&nbsp;&nbsp;&nbsp;&nbsp;Accumulated deficit from prior years***

PEMEX has recorded negative earnings in the past several years. However, the *Ley de Concursos Mercantiles* ("Commercial Bankruptcy Law of Mexico") is not applicable to Petróleos Mexicanos. Furthermore, the financing agreements to which PEMEX is a party do not provide for financial covenants that would be breached or events of default that would be triggered as a consequence of negative equity.

***F.&nbsp;&nbsp;&nbsp;&nbsp;Uncertainty related to going concern***

The consolidated financial statements have been prepared assuming PEMEX will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business. However, significant doubt about PEMEX's ability to continue as a going concern exists due to (1) recurring net losses, (2) negative equity and (3) dependence on equity contributions from the Mexican Government, as described below.

*Facts and conditions*

(1) Recurring net losses

During 2025 and 2024, PEMEX recognized net losses of Ps. (81,665,432) and Ps. (780,587,954), respectively. The recurring net losses in recent years have directly impacted PEMEX's consolidated financial position and constitute an indicator of uncertainty regarding its ability to generate sufficient resources to fund its operations and meet its financial obligations in the normal course of business. These losses are primarily attributable to PEMEX's heavy fiscal burden resulting from hydrocarbon extraction duties, including the Welfare Oil Duty effective as of January 1, 2025 (see Note 21), and the insufficiency of operating cash flows to fully fund both operations and capital expenditure programs.

(2) Negative equity

As of December 31, 2025 and 2024, PEMEX has a negative equity of Ps. (1,905,806,170), and Ps. (1,983,775,736), respectively. The negative equity position is a cumulative result of the recurring net losses described above. As of December 31, 2025 and 2024, PEMEX also has negative working capital of Ps. 530,541,020 and Ps. 767,968,661, respectively, and short-term debt principal maturities (including interest payable) of Ps. 345,227,971 as of December 31, 2025. These conditions represent additional factors of uncertainty regarding PEMEX's ability to continue as a going concern.

(3) Dependence on equity contributions from the Mexican Government

PEMEX's operational continuity and timely compliance with its financial obligations depend on the recurrence of equity contributions from the Mexican Government. During 2025, PEMEX received equity contributions of Ps. 395,313,191 from the Mexican Government, exceeding the initial expected contributions of Ps. 136,120,300 due to additional support for PEMEX's liability management strategy. PEMEX has substantial debt, incurred mainly to finance capital investment projects and operating expenses, and in the absence of continued Mexican Government support, PEMEX would be unable to meet its financial obligations as they become due.

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies**

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

PEMEX has budget autonomy, and, in public finance terms, is subject to the cash flows financial balance goals approved in the *Decreto de Presupuesto de Egresos de la Federación* ("Federal Expenditure Budget Decree"). This represents the difference between its gross revenues (inflows) and its total budgeted expenditures (outflows) including the financial cost of its debt, which is proposed by the SHCP and approved by the Chamber of Deputies. The Federal Budget for 2026 authorized PEMEX to have a financial balance budget of Ps. 263,476,300, and conduct financing activities that do not represent a net debt in terms of public debt greater than Ps. 261,585,290 and other financing activities that do not represent net public debt. These targets are determined considering premises such as the exchange rate and the international price of the Mexican crude oil, and in case of significant fluctuations, the results could impact the goals determined in the budget. This financial balance does not consider the payment of principal during 2026, which PEMEX expects to cover with equity contributions from the Mexican Government.

*Other relevant factors*

In 2025, certain ratings agencies upgraded PEMEX's credit rating, mainly driven by PEMEX's operating performance, liquidity and the Mexican Government's ability and willingness to provide PEMEX with additional liquidity, as well as fluctuations in crude oil prices and the Mexican Government's sovereign debt rating. These factors may influence PEMEX's access to the financial markets, the cost and terms of PEMEX's new debt and contract renegotiations that PEMEX may carry out during 2026. These conditions have impacted PEMEX's financial performance.

During 2025, certain credit agencies upgraded the credit ratings of PEMEX. On August 1, 2025, Fitch Ratings upgraded PEMEX's long-term local and foreign currency issuer default to "BB" from "B+", removed its Rating Watch Positive and upgraded the rating of its senior unsecured notes outstanding to "BB" from "B+"/"RR4" with a stable outlook. Notwithstanding credit rating upgrades, the rating agencies continue to express certain concerns regarding PEMEX's operating performance and liquidity position.

Beginning in the second half of 2025, PEMEX implemented a comprehensive liability management strategy which resulted in an approximately 23% reduction in the consolidated financial debt compared to the levels reported as of December 31, 2024. This decrease was primarily attributable to equity contributions from the Mexican Government, other liability management transactions, and prepayments of outstanding indebtedness. Despite these efforts, PEMEX still retains a significant level of financial debt.

As part of its liquidity management strategy, PEMEX implemented a supplier payment program through amended agreements designed to extend payment terms with suppliers and contractors, with the objective of settling balances incurred in 2025 over a period of up to eight years, through quarterly payments of principal and interest. As of December 31, 2025, the restructured amount under this program totaled Ps. 193,033,065.

The combined effect of the above-mentioned events and conditions, in particular the recurring net losses, the negative

equity and the dependence on equity contributions from the Mexican Government, indicates significant doubt about PEMEX's ability to continue as a going concern.

*Actions* 

PEMEX and the Mexican Government are carrying out the following actions, among others, to preserve liquidity and let PEMEX pay its commitments:

The application of the tax credit decree to automotive fuels published in the Official Gazette of the Federation of March 4, 2022, was in effect for 2024 and 2025 and remains in effect through 2026. This decree allows PEMEX to substantially recover from the Mexican Government the difference between the international reference price of gasoline and diesel and the price at which they trade in the domestic market, accounting for inflation.

**Petróleos Mexicanos, State-Owned Public Company and Subsidiary Companies**

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

Pursuant to the Energy Reform Decree, Petróleos Mexicanos is no longer subject to income tax as of November 1, 2024 (and, prior to their dissolution, the former subsidiary entities were also exempt).

Effective January 1, 2025, the Welfare Oil Duty came into effect, consolidating the Profit-Sharing Duty, the Hydrocarbon Extraction Duty and the Hydrocarbon Exploration Duty payable into a single obligation, requiring only provisional and annual tax returns, which is set at a general rate of 30% on oil and fuel production and 11.63% for non-associated gas.

As of December 31, 2025, PEMEX received equity contributions of Ps. 395,313,191 from the Mexican Government, exceeding the initial expected contributions of Ps.136,120,300 due to the additional support granted by the Mexican Government in connection with PEMEX's liability management strategy. These contributions were used to strengthen PEMEX's financial position. The Mexican Government's Federal Budget for 2026 includes Ps.263,476,317, which will be received during 2026. As of April 15, 2026, PEMEX has received Ps.58,346,391 in capital contributions.

Additionally, during 2025, PEMEX executed liability management transactions aimed at extending debt maturities and reducing financing costs, in line with its financing strategy. PEMEX's capacity to refinance its short-term debt depends on factors beyond its control.

In February 2026, PEMEX carried out a refinancing transaction and optimization of its debt maturity profile aimed to address short-term maturities, extending repayment terms, and improving financial conditions, as part of the initiatives implemented to strengthen its liquidity and capital structure.

The Revenue Law for 2026 also authorized PEMEX to incur a net additional indebtedness up to Ps.261,585,290 (Ps.160,619,600 and U.S.$5,342,100), which is considered as public debt by the Mexican Government and may be used to partially cover its financial balance in 2026.

PEMEX reviews and aligns its capital expenditures portfolio in accordance with updated economic assumptions on a periodic basis and giving priority to those projects which increase production in an efficient manner and at the lowest cost.

On August 5, 2025, PEMEX presented its *Plan Estratégico 2025–2035* (the "Strategic Plan"), grounded in the principles of energy sovereignty, security and sustainable development, that aims to restore and enhance its operational, financial and institutional conditions in line with Mexico's national energy policy. The Strategic Plan is structured around an operational strategy, aimed at boosting production across hydrocarbons, petrochemicals and fertilizers while reducing greenhouse gas (GHG) emissions and reinforcing social responsibility; and a capitalization and financing strategy, aimed at strengthening PEMEX's financial stability through capital structure optimization, debt reduction and restructuring, cost reduction and sustainable financing.

Petróleos Mexicanos is not subject to the Commercial Bankruptcy Law of Mexico and none of PEMEX's existing financing agreements include any financial covenants that could lead to the demand for immediate payment of its debt due to having negative equity or non-compliance with financial ratios.

PEMEX prepared its consolidated financial statements as of December 31, 2025 and 2024 on a going concern basis. There are conditions that have generated material uncertainty and significant doubt concerning PEMEX's ability to continue as a going concern, in particular the recurring net losses, the negative working capital and negative equity, and the dependence on equity contributions from the Mexican Government to meet its financial obligations. Those financial statements do not contain any adjustments that would be required if they were not prepared on a going concern basis.

***G.&nbsp;&nbsp;&nbsp;&nbsp;Non-controlling interest***

PEMEX does not currently own all of the shares of PMI CIM and COMESA; therefore, variations in income and equity from these entities are also presented in the consolidated statements of changes in equity (deficit) as "non-controlling interest."

<sup>(1)</sup> In accordance with Resolution RES / 179/2017, issued by the CRE, losses from fuels subtraction are losses outside the scope of the contemplated operating costs as a result of various illicit actions, including the theft of and illicit market in fuels.

Until its dissolution on March 19, 2025, Pemex Logistics was responsible for distributing hydrocarbons through pipelines and for the received products, preserving their quality and delivering them from the point of reception to the user at the point of destination. As of March 19, 2025, these activities are carried out by Petróleos Mexicanos and reported within the Other Operating Subsidiary Companies segment (see Notes 1 and 6). The volume of missing hydrocarbons is determined through monthly calculations.

<sup>(2)</sup> The variation in inventories represents the difference between the balances as of the beginning and the end of the year, as well as variations in standard and real costs. During 2025, the variation was mainly due to variations in standard and real costs and the difference between the balances as of the beginning and the year.

since an unfavorable resolution is not expected in such proceedings, with the exception of the proceeding described in further detail in this Note.

PEMEX is involved in various civil, tax, criminal, administrative, labor and commercial lawsuits and arbitration proceedings. The results of these proceedings are uncertain as of the date of these consolidated financial statements. As of December 31, 2025 and 2024, PEMEX had accrued a reserve of Ps. 13,424,603 and Ps. 13,186,811, respectively, for these contingent liabilities.

Following the dissolution of the subsidiary entities on March 19, 2025 (see Note 1), Petróleos Mexicanos assumed, as successor, the position of party in all legal proceedings in which the subsidiary entities were named as plaintiff or defendant. References to Pemex Exploration and Production, Pemex Industrial Transformation and Pemex Logistics in the descriptions below reflect the original parties to the relevant proceedings.

As of December 31, 2025, the current status of the principal lawsuits in which PEMEX is involved is as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On April 4, 2011, Pemex Exploration and Production was summoned before the *Séptima Sala Regional Metropolitana* ("Seventh Regional Metropolitan Court") of the *Tribunal Federal de Justicia Fiscal y Administrativa* ("Tax and Administrative Federal Court") in connection with an administrative claim (No. 4957/11-17-07-1) filed by EMS Energy Services de México, S. de R.L. de C.V. and Energy Maintenance Services Group I. LLC requesting that Pemex Exploration and Production's termination of the public works contract be declared null and void. In a concurrent proceeding, the plaintiffs also filed an administrative claim (No. 13620/15-17-06) against Pemex Exploration and Production before the *Sexta Sala Regional Metropolitana* ("Sixth Regional Metropolitan Court") of the Tax and Administrative Federal Court in Mexico City seeking damages totaling U.S.$193,713 related to the above-mentioned contract. Pemex Exploration and Production filed a response requesting the two administrative claims be joined in a single proceeding, which was granted. On April 30, 2019, a judgment was issued by the *Segunda Sección de la Sala Superior* ("Second Section of the Superior Court") in favor of Pemex Exploration and Production. On June 25, 2019, the plaintiffs filed an amparo (D.A. 397/2019) before the *Tercer Tribunal Colegiado en Materia Administrativa del Primer Circuito* ("Third Administrative Joint Court of the First Circuit"), which was granted. On March 12, 2020, Pemex Exploration and Production filed a motion to review against the resolution granting this amparo before the Third Administrative Joint Court of the First Circuit. On October 1, 2020, in compliance with the amparo ruling, the Third Administrative Joint Court declared the challenged resolution null and void, determined that termination of the contract due to causes attributable to the defendant authority was not warranted, denied the economic relief requested by the plaintiffs, and upheld the validity of the resolution challenged in the related proceeding. On February 24, 2022, an amparo (350/2020) was granted in favor of EMS Energy Services de México, S. de R.L. On March 17, 2022, a motion was filed to draw the resolution by the *Suprema Corte de Justicia de la Nación* (Supreme Court of Justice of the Nation). On June 16, 2022, a resolution was issued in connection with the amparo 350/2020 stating that the plaintiffs partially proved their requests, and the resolution was declared null and void, among others. On August 1, 2022, a motion to review this resolution was filed and admitted (RF 574/2022) by the Third Administrative Joint Court of the First Circuit. On September 13, 2022, representations were made under the amparo (D.A. 539/2022) filed by the plaintiffs before such Court. On April 18, 2024, a resolution was issued by the Third Administrative Joint Court of the First Circuit modifying the appealed judgment, granting the Amparo to EMS Energy Services de México, S. de R.L. de C.V. On July 10, 2024, the Superior Court ordered Pemex Exploration and Production to (i) pay U.S.$27,244 plus Value Tax Added (VTA); (ii) pay damages; (iii) refund the penalties applied for an amount of U.S.$4,143 plus VTA; (iv) refund the standby letter of credit for U.S.$13,975 and (v) payment of financial expenses. On August 27, 2024, the tax review was filed. An Amparo was filed directly against the compliance with the judgment issued on July 10, 2024, and was admitted under the case D.A. 497/2024, by the Third Administrative Joint Court of the First Circuit. As of the date of these consolidated financial statements, a final resolution is still pending.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Micro Smart Systems de México, S. de R.L. de C.V. (MSSM) filed before the *Sala Regional del Golfo Norte* (Regional Court of the North Gulf) of the Tax and Administrative Federal Court (574/22-18-01-8) challenging a settlement statement dated February 17, 2022 related to a works contract number No. 424049831 issued by Pemex Exploration and Production and seeking U.S.$240,488.

requesting Pemex Exploration and Production evidence, which was filed on August 8, 2022, and admitted by the Regional Court of the North Gulf on August 17, 2022. On September 2, 2022, this Regional Court confirmed the rejection of the evidence filed by the plaintiffs. On September 29, 2022, the First Section of the Superior Court denied a compliant motion filed by MSSM against the settlement statement dated February 17, 2022. On October 3, 2022, it was agreed that the plaintiff would be heard, making various statements in relation to the defense of the claim. On October 7, 2022 a resolution was issued regarding the complaint filed by the plaintiff confirming the resolution issued on August 28, 2018 (through which the prior resolution dated April 3, 2018, was partially revoked, leaving without effect the warning contained therein regarding the submission of the administrative file) and such resolution was upheld.. On November 14, 2022, the First Section of the Superior Court agreed to an amparo proceeding (1833/2022) against acts issued by the *Juzgado Octavo de Distrito en Materia Administrativa* (Eighth Administrative District Court), in Mexico City and required such authority to render the justified report. On May 17, 2023, the Regional Court of the North Gulf, summoned the parties to file its rejoinders, which were filed by Pemex Exploration and Production on June 14, 2023. On June 22, 2023, the Regional Court ordered the file to be sent to the First Section of the Superior Court acknowledged that both parties had exercised their right to submit closing arguments, declared the close of the evidentiary stage of the proceeding, and ordered the file to be sent to the First Section of the Superior Court. On September 19, 2023, the Northern Gulf Regional Court sent by certified mail the file to the First Section of the Superior Court for a final resolution. On November 14, 2023, the Superior Court published a resolution requiring the Northern Gulf Regional Court to send all the documents that integrate the evidentiary file offered in the trial. On December 12, 2023, an extract of a clarification agreement concerning the referral of evidence to the Superior Court was notified in the jurisdictional gazette. On June 14, 2024, the Superior Court issued a resolution, (574/22-18-01-8/1549/23-PL-09-04), designating the delegates by Micro Smart Systems de México S. de R.L. de C.V. On September 9, 2024, the trial was suspended until a determination of compliance with the resolution of the First Section of the Superior Chamber issued within the trial 752/17-18-01-7/1625/19-S1-05-04 becomes final. On February 17, 2025, the Eighth District Court in Administrative Matters of the First Circuit denied the amparo filed by Micro Smart Systems de México S. de R.L. de C.V. (case 1560/2024-VIII) against a September 10, 2024 resolution of the First Section of the Superior Chamber of the Federal Court of Administrative Justice (Tribunal Federal de Justicia Administrativa). In that resolution, the TFJA had found that its prior judgment was complied with because the contested settlement was annulled and replaced with a new one reflecting the effects ordered in the nullity judgment. On March 11, 2025, within amparo proceeding 1560/2025-VIII before the Eighth District Court for Administrative Matters of the First Circuit, Micro Smart Systems filed a review appeal, which was acknowledged by court order. On April 3, 2025, the First Section of the Superior Chamber of the Federal Court of Administrative Justice decided to wait for the outcome of the amparo case, related to the September 10, 2024, judgment challenged in amparo proceeding 1560/2024-VIII, before lifting a suspension issued on September 4, 2024, and before issuing its final ruling. On April 21, 2025, the Twenty-Fourth Administrative Joint Court of the First Circuit admitted an ancillary appeal for review filed by Pemex Exploration and Production. On June 25, 2025, through a resolution issued within the amparo review proceeding R.A. 519/2025, the Third Joint Administrative Court of the First Circuit determined, due to court assignment and considering that it had previously taken cognizance of the amparo review R.A. 153/2023 — which derived from the nullity trial 752/17-18-01-7/1625/19-S1-05-04 — to assume jurisdiction over the matter. As of the date of these consolidated financial statements, the final resolution of this process is pending.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Constructora Norberto Odebrecht, S.A de C.V. filed an administrative claim against Pemex Industrial Transformation (file No. 4742/19-17-01-7) seeking U.S.$113,582 and Ps.14,607 in connection with a termination resolution (no. 1,757) dated January 14, 2019, and issued by Pemex Industrial Transformation, which awarded U.S.$51,454 in favor of Pemex Industrial Transformation. The claim was admitted. On November 11, 2020, Pemex Industrial Transformation filed a response to this claim. The accounting expert filed his opinion. On June 2, 2022 an opinion by the accounting expert appointed by Pemex Industrial Transformation was filed. A third accounting expert was appointed, who did not ratify his position; therefore, a resolution dated October 2, 2023 was issued requesting the Expert Unit to appoint another expert. On February 2, 2024, the independent accounting expert accepted his assignment and was awarded 15 days to render his report. On March 19, 2024, the Superior Court decided to exercise its power of attraction. On May 2, 2024, the Superior Court issued a resolution requesting the Expert Unit to appoint another expert, since the previously appointed expert did not ratify the report. On August 2, 2024, a resolution was issued, granting the independent expert a term to render the report and ratify it. On February 28, 2025, the investigation was declared concluded, and the records were sent to the *Pleno*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On November 24, 2021, Pemex Industrial Transformation filed a repeal request (no. RRL2021014568) seeking that the resolutions dated October 7, 2021, issued by the Hydrocarbons Verification Manager of the Tax Administration Service be declared null and void.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On June 17, 2025, COMPAÑÍA MINERA SAN ALEJANDRO, S.A. de C.V. filed a civil lawsuit against Petróleos Mexicanos seeking indemnification related to the alleged breach of Preparatory Contract PM-2019-004. The ordinary civil action, docketed as case 2065/2025, was filed before the Fourteenth District Court for Civil Matters in Mexico City. The plaintiff also claimed damages in the amount of Ps.7,316,929 for equipment maintenance costs, as well as other resources and expenses incurred during the contractual period, and an additional Ps.2,353,719 for loss of fair profit. On June 20, 2025, PEMEX submitted its response to the claim, denying liability and raising exceptions and defenses. On June 24, 2025, the claim was deemed answered, notice was given to the opposing party, and the objection regarding the impropriety of the procedural route was considered filed, which remains pending resolution. By resolution dated November 4, 2025, the claim filed by the plaintiff's former legal representative was dismissed; against such ruling, the petitioner filed an appeal, which remains pending resolution. As of the date of these consolidated financial statements, the final resolution of this action is pending.

The results of these proceedings are uncertain until their final resolutions are issued by the appropriate authorities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**E. Amending agreements with suppliers**

Petróleos Mexicanos issued amending agreements to extend the payment term under various agreements with suppliers and contractors, to pay the balances generated in 2025 over the course to 8 years, through quarterly payments of principal and interest. As of March 31, 2026, the amount due to suppliers that is governed by these agreements amounted to Ps.250,498,559.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**F. Oil spill in the Gulf of Mexico**

Subsequent to December 31, 2025, scientific analyses pointed to evidence that a hydrocarbon spill occurred in February 2026 in the Abkatun-Cantarell area of the Gulf of Mexico and that the hydrocarbons were subsequently dispersed and weathered by marine dynamics. On April 16, 2026, President Claudia Sheinbaum instructed an interinstitutional group to investigate the origin of the event.

Following a review of satellite vessel-movement images, operating logs and related information, PEMEX identified several irregularities in the handling and reporting of the event, including a loss of mechanical integrity in, and repairs to, an oil pipeline that were not reported to PEMEX's Chief Executive Officer or senior management, as well as a hydrocarbon leak in PEMEX facilities that had been systematically denied by local operational areas. Pemex's Chief Executive Officer brought these matters to the attention of the *Fiscalía General de la República* and the *Secretaría Anticorrupción y Buen Gobierno*, and PEMEX removed from their positions the Subdirector of Safety, Occupational Health and Environmental Protection, the Coordinator of Marine Control, Spills and Waste, and the Head of Spills and Waste, pending completion of the investigation.

PEMEX also continues containment, cleanup, waste collection and treatment, environmental monitoring and related community-support actions, including collection of approximately 915 tons of waste containing hydrocarbons mixed with sand, driftwood and sargassum and transportation of those materials to ASEA-authorized treatment plants. PEMEX continues to cooperate with the interinstitutional group in those response efforts until the coastal and marine environment has been fully restored and the collected waste has been safely disposed of.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**G. Approval of Financial Statements**

The accompanying consolidated financial statements were authorized for issuance in PEMEX's annual report on Form 20-F by Mr. Víctor Rodríguez Padilla, Chief Executive Officer, Mr. Juan Carlos Carpio Fragoso, Chief Financial Officer, Mr. Óscar René Orozco Piliado, Deputy Director of Accounting and Tax, and Mr. Ernesto Balcázar Hernández, Associate Managing Director of Accounting on April 30, 2026, hereby updated subsequent events, to be filed with the United States Securities and Exchange Commission.

**NOTE 29.&nbsp;&nbsp;&nbsp;&nbsp;SUBSIDIARY GUARANTOR INFORMATION**

Background and effect of the dissolution of the Subsidiary Guarantors

Prior to March 19, 2025, Petróleos Mexicanos' payment obligations under its debt securities registered with the United States Securities and Exchange Commission ("SEC") were guaranteed by Pemex Exploration and Production, Pemex Industrial Transformation and Pemex Logistics (collectively, the "Former Subsidiary Guarantors"). These guarantees were full, unconditional, joint and several. The Subsidiary Companies (as defined in Note 1) were not guarantors of any of Petróleos Mexicanos' indebtedness (the "Non-Guarantor Subsidiaries").

On March 19, 2025, pursuant to the 2025 Petróleos Mexicanos Law, the Former Subsidiary Guarantors were dissolved and all of their assets, liabilities, rights and obligations, including their obligations under the guarantees described above, were assumed by, and transferred to Petróleos Mexicanos, which became the successor of the Former Subsidiary Guarantors as a matter of Mexican law (see Note 1). As a result, effective March 19, 2025, Petróleos Mexicanos is the sole obligor — both as primary obligor and as successor to the Former Subsidiary Guarantors — under all SEC-registered debt securities. There are no longer any separate legal entities acting as guarantors of Petróleos Mexicanos' indebtedness.

The 2025 Petróleos Mexicanos Law provides that the dissolution of the subsidiary entities does not affect any payment obligations previously contracted, nor does it alter the guarantees provided by Petróleos Mexicanos or the dissolved entities, whether in Mexico or abroad. Notwithstanding this provision, because the Former Subsidiary Guarantors and Petróleos Mexicanos have merged into a single legal entity, the guarantees have been effectively extinguished by operation of law through the merger of the obligor and the guarantor. All payment obligations under the guaranteed debt securities continue in full force and effect as direct obligations of Petróleos Mexicanos.

SEC-registered debt securities outstanding

The following table sets forth, as of December 31, 2025, the principal amount outstanding of the SEC-registered debt securities originally issued by the Pemex Project Funding Master Trust (the "Master Trust") and subsequently assumed by Petróleos Mexicanos as primary obligor. The Master Trust was dissolved effective December 20, 2011 and is no longer consolidated in the financial statements of PEMEX as of December 31, 2011 and thereafter.

Historical supplemental condensed consolidating financial information

The following condensed consolidating financial information is presented for the years ended December 31, 2024 and 2023 to provide investors with the historical financial information of the Former Subsidiary Guarantors during the periods in which the guarantee structure was in effect.

As described above, the Former Subsidiary Guarantors were dissolved on March 19, 2025, and all of their assets, liabilities, rights and obligations were transferred to Petróleos Mexicanos at historical cost without gain or loss. Accordingly, no condensed consolidating financial information is presented for the year ended December 31, 2025 or as of December 31, 2025, as the Former Subsidiary Guarantors did not exist as separate legal entities as of that date.

These condensed consolidated statements for the years ended December 31, 2024 and 2023 were prepared in accordance with IFRS, with one exception: for the purposes of the presentation of the subsidiary guarantor information, the former subsidiary entities and the Subsidiary Companies were accounted for as investments under the equity method by Petróleos Mexicanos. Earnings of subsidiaries are therefore reflected in Petróleos Mexicanos' investment account and earnings. The principal elimination entries eliminate Petróleos Mexicanos' investment in subsidiaries and inter-company balances and transactions. The Former Subsidiary Guarantors were 100% owned subsidiaries of the Mexican Government. The Subsidiary Companies collectively comprise the Non-Guarantor Subsidiaries

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

**NOTE 30.&nbsp;&nbsp;&nbsp;&nbsp;SUPPLEMENTARY INFORMATION ON OIL AND GAS EXPLORATION AND PRODUCTION ACTIVITIES (UNAUDITED)**

Under the Mexican Constitution, all crude oil and other hydrocarbon reserves located in the subsoil of Mexico are owned by the Mexican nation and not by PEMEX. In August 2014, through the Round Zero process, the Mexican Government granted PEMEX the right to extract, but not own, certain petroleum and other hydrocarbon reserves in Mexico through assignment deeds.

This note provides supplementary information on the oil and gas exploration, development and production activities of PEMEX in compliance with the U.S. Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 932 10-5 "Extractive Activities—Oil and Gas" ("ASC Topic 932") and Accounting Standards Update 2010-03 (see Note 3-G).

As of the date of these consolidated financial statements, all exploration and production activities of PEMEX are conducted in Mexico. The supplemental data presented herein reflect information for all of PEMEX's oil and gas producing activities.

PEMEX does not have property acquisition costs because the oil reserves it exploits are owned by the Mexican nation.

Exploration costs include costs of geological and geophysical studies of fields in the amount of Ps. 17,368,569, Ps.14,672,428 and Ps.16,589,953 for 2025, 2024 and 2023, respectively. These costs are accounted for as geological and geophysical exploration expenses, in accordance with the successful efforts method of accounting.

Development costs include those costs incurred in obtaining access to proved reserves and providing facilities for extracting, treating, gathering and storing oil and gas.

***E.&nbsp;&nbsp;&nbsp;&nbsp;Crude oil and natural gas reserves (unaudited)***

Under the Mexican Constitution, all oil and other hydrocarbon reserves located in the subsoil of Mexico are owned by the Mexican nation and not by PEMEX. Under the Petróleos Mexicanos Law, PEMEX has the right to extract, but not own, these reserves, and to sell the resulting production. The exploration and development activities of PEMEX are limited to reserves located in Mexico.

Proved oil and natural gas reserves are those estimated quantities of crude oil, natural gas and natural gas liquids which geological and engineering data demonstrate 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.

Proved reserves estimates as of December 31, 2025 were prepared by the Exploration and Extraction segment and were reviewed by the Independent Engineering Firms (as defined below), which audit its estimates of hydrocarbon reserves. According to the *Lineamientos que Regulan los Procedimientos de Cuantificación y Certificación de Reservas de la Nación* (Guidelines for Regulating the Nation's Reserves Quantification and Certification Procedures), the Ministry of Energy should review and approve Hydrocarbon Reserves reports submitted by Mexico's operators in the month of April or in some unforeseen circumstances in September. As of the date of these consolidated financial statements, the proved reserves estimates as of December 31, 2025 have not been approved by the Ministry of Energy.

PEMEX estimates proved reserves based on generally accepted petroleum engineering and evaluation methods and procedures, which are based primarily on applicable SEC regulations and, as necessary, the SPE's publication entitled Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information, dated June 25, 2019 and other

(Figures stated in thousands, except as noted)

SPE publications, including the SPE's publication entitled Petroleum Resources Management System, as well as other technical sources, including Estimation and Classification of Reserves of Crude Oil, Natural Gas, and Condensate, by Chapman Cronquist, and Determination of Oil and Gas Reserves, Petroleum Society Monograph Number 1, published by the Canadian Institute of Mining and Metallurgy & Petroleum. The choice of method or combination of methods employed in the analysis of each reservoir is determined by:

• Experience in the area

• Stage of development

• Quality and completeness of basic data

• Production and pressure histories

Reserves data set forth herein represents only estimates. Reserves valuation is a subjective process of estimating underground accumulations of crude oil and natural gas that cannot be measured in an exact manner. The accuracy of any reserves estimate depends on the quality of available data, engineering and geological interpretation and professional judgment. As a result, estimates of different engineers may vary. In addition, the results of drilling, testing and producing subsequent to the date of an estimate may lead to the revision of an estimate.

During 2025, PEMEX did not record any material increase in PEMEX's hydrocarbons reserves as a result of the use of new technologies.

In order to ensure the reliability of PEMEX's reserves estimation efforts, it has undertaken the internal certification of its estimates of reserves since 1996. PEMEX has established certain internal controls in connection with the preparation of its proved reserves estimates. Initially, teams of geoscientists from PEMEX exploration and extraction business units (with each of these units covering several projects) prepare the reserves estimates, using different estimation processes for valuations relating to new discoveries and developed fields, respectively. Subsequently, the regional reserves offices collect these reserves estimates from the units and request that the *Gerencia de Recursos y Reservas de Hidrocarburos*, (Office of Hydrocarbon Resources and Reserves), the central hydrocarbon reserves management body of PEMEX, review and certify such valuations and the recording of the related reserves. This internal certification process is undertaken in accordance with internal guidelines for estimating and classifying hydrocarbon reserves, which are based on the SEC's rules and definitions.

The Office of Hydrocarbon Resources and Reserves, which additionally oversees and conducts an internal audit of the above process, consists entirely of professionals with geological, geophysical, petrophysical and reservoir engineering backgrounds. The engineers who participate in PEMEX's reserves estimation process are experienced in the following areas: reservoir numerical simulation; well drilling and completion; pressure, volume and temperature (PVT) analysis; analytical tools used in forecasting the performance of the various elements comprising the production system; and design strategies in petroleum field development. Furthermore, all of PEMEX's personnel have been certified by the *Secretaría de Educación Pública* (Ministry of Public Education), most have earned master's degrees in areas of study such as petroleum engineering, geology and geophysical engineering and they possess an average of over twenty years of professional experience.

In addition to this internal review process, PEMEX final reserves estimates are audited by independent engineering firms. Three independent engineering firms audited PEMEX estimates of proved reserves as of December 31, 2025 or January 1, 2026: DeGolyer and MacNaughton ("DeGolyer"), Ryder Scott Company L.P ("Ryder Scott") and GLJ LTD. ("GLJ"), together, the "Independent Engineering Firms." The reserves estimate reviewed by the Independent Engineering Firms totaled 76.1% of PEMEX's estimated proved reserves. The remaining 23.9% of PEMEX's estimated proved reserves consisted of reserves located, among others, in onshore fields in the northern region of Mexico, certain offshore fields and fields related to exploration and production contracts, in which a corresponding third party is responsible for assessing the volume of reserves.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

GLJ audited the reserves in the Cantarell, Ku Maloob Zaap, Reynosa, Veracruz, Cinco Presidentes and Macuspana-Muspac, business units; Ryder Scott audited the reserves in the Poza Rica-Altamira, Bellota-Jujo, Samaria-Luna, Abkatún-Pol-Chuc and Litoral de Tabasco business units, and DeGolyer and MacNaughton audited the reserves in the fields recently added to our inventory registry. The audits conducted by the Independent Engineering Firms consisted primarily of: (1) analysis of historical static and dynamic reservoir data provided by PEMEX; (2) construction or updating of the Independent Engineering Firms' own static and dynamic reservoir characterization models of some of the fields; (3) economic analysis of the fields; and (4) review of PEMEX production forecasts and reserves estimates.

Since reserves estimates are, by definition, only estimates, they cannot be reviewed for the purpose of verifying exactness. Instead, the Independent Engineering Firms conducted a detailed review of PEMEX reserves estimates so that they could express an opinion as to whether, in the aggregate, the reserves estimates that PEMEX furnished were reasonable and had been estimated and presented in conformity with generally accepted petroleum engineering and evaluation methods and procedures.

All questions, including any suggested modifications to proved reserves estimates, that arose during the Independent Engineering Firms' review process were resolved by PEMEX to the satisfaction of the Independent Engineering Firms. The Independent Engineering Firms have concluded that PEMEX's estimated total proved oil and natural gas reserve volumes set forth in this report are, in the aggregate, reasonable and have been prepared in accordance with Rule 4-10(a) are consistent with international reserves reporting practice and are in accordance with the revised oil and gas reserves disclosure provisions of ASC Topic 932.

PEMEX´s total proved developed and undeveloped reserves of crude oil, condensates and liquefiable hydrocarbons recoverable from field processing plants decreased by 2.6% in 2025, from 5,494.5 million barrels at December 31, 2024 to 5,351.9 million barrels at December 31, 2025. PEMEX's proved developed reserves of crude oil, condensates and liquefiable hydrocarbons recoverable from processing plants decreased by 8.7% in 2025, from 3,463.9 million barrels on December 31, 2024 to 3,162.1 million barrels at December 31, 2025. The proved reserves of crude oil, condensates and liquefiable hydrocarbons added by PEMEX in 2025 through revisions, extensions and discoveries totaled 507.4 million barrels, which was not sufficient to offset total production for the year of 650.0 million barrels of crude oil, condensates and liquefiable hydrocarbons.

PEMEX's total proved developed and undeveloped dry gas reserves increased by 8.4% in 2025, from 10,173.6 billion cubic feet as of December 31, 2024 to 11,025.9 billion cubic feet as of December 31, 2025. PEMEX's proved developed dry gas reserves increased by 22.2% in 2025, from 5,773.4 billion cubic feet as of December 31, 2024 to 7,054.0 billion cubic feet as of December 31, 2025. This increase was principally due to an upsurge in proved developed dry gas reserves of Ixachi field. The amount of proved developed and undeveloped dry gas reserves added in 2025 was sufficient to offset the level of production in 2025, which amounted to 901.0 billion cubic feet of dry gas. PEMEX's proved undeveloped dry gas reserves decreased by 9.7% in 2025, from 4,400.2 billion cubic feet as of December 31, 2024 to 3,971.9 billion cubic feet as of December 31, 2025. This decrease in proved undeveloped reserves was due to the development of the Ixachi field, mainly due to the drilling of development wells and revisions, which allowed these reserves to be classified as proven developed reserves.

During 2025, our exploration activities in shallow waters of the Gulf of Mexico and onshore regions resulted in the discovery of two new hydrocarbon fields (Konen and Iklum) and confirmed the extension of an existing field (Bakte) due to an appraisal well that was determined to be viables. Together, these discoveries led to the incorporation of 12.2 million barrels of oil equivalent of proved reserves.

The following three tables of crude oil and dry gas reserves set forth PEMEX's estimates of its proved reserves determined in accordance with Rule 4-10(a).

PEMEX reserve-replacement ratio, or RRR, for a given period is calculated by dividing the sum of proved reserves additions due to discoveries, developments, delineations and revisions by that period's total production. During 2025, PEMEX obtained an increase of 844.5 million barrels of oil equivalent of proved reserves as aggregated from discoveries, revisions, delimitations and development and production, which represents a RRR of 102.6% in 2025, an increase as compared to a RRR of 96.6% in 2024.

PEMEX's reserves production ratio, which is presented in terms of years, is calculated by dividing the estimated remaining reserves at the end of the relevant year by the total production of hydrocarbons for that year. As of December 31, 2025, this ratio is 9.1 years for proved reserves.

***F.&nbsp;&nbsp;&nbsp;&nbsp;Standardized measure of discounted future net cash flows related to proved oil and gas reserves (unaudited)***

The standardized measure tables presented below relate to proved oil and gas reserves excluding proved reserves scheduled to be produced beginning the year 2051. This measure is presented in accordance with ASC Topic 932.

Estimated future cash inflows from production are computed by applying average prices of oil and gas on the first day of each month of 2025. Future development and production costs are those estimated future expenditures needed to develop and produce the year-end estimated proved reserves after a net cash flows discount factor of 10%, assuming constant year-end economic conditions.

Future tax expenses are computed by applying the appropriate year-end statutory tax rates with consideration of the tax rates of the new fiscal regime for PEMEX already legislated for 2025 to the future pre-tax net cash flows related to PEMEX's proved oil and gas reserves.

Notes to the consolidated financial statements

(Figures stated in thousands, except as noted)

The estimated future payment of taxes was calculated based on the latest fiscal regime applicable by decree to PEMEX, published in the Official Gazette of the Federation on March 18, 2025.

The standardized measure provided below represents a comparative benchmark value rather than an estimate of expected future cash flows or fair market value of PEMEX's production rights. There are numerous uncertainties inherent in estimating quantities of proved reserves and in projecting future rates of production and timing of development expenditures, including many factors beyond the control of the producer. Accordingly, reserve estimates may be materially different from the quantities of crude oil and natural gas that are ultimately recovered.

All definitions in the Original Indenture shall be read in a manner consistent with the terms of this Tenth Supplemental Indenture.

**ARTICLE TWO**

AMENDMENTS TO INDENTURE

<u>Section 1.01</u>*. Regular Record Date*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)With respect to any New Securities, the definition of "Regular Record Date" in Section 1.01(a) is hereby amended and restated in its entirety as follows:

"<u>Regular Record Date</u>" for the interest payable on any Interest Payment Date means the date &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;specified for that purpose as contemplated by Section 2.02, which date shall be, unless otherwise specified pursuant to Section 2.02, the date one Business Day prior to such Interest Payment Date.

[**<u>Include if Note is a Registered Note</u>** — (b) The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, unless otherwise specified on the face hereof or in the Final Terms, be paid to the person in whose name this Note (or one or more predecessor Notes) is registered at the close of business on the date one Business Day prior to such Interest Payment Date (the "Regular Record Date"); *provided* that interest payable at Stated Maturity will be payable to the person to whom principal shall be payable; and *provided*, *further*, that if this Note is a Global Security, any payment of interest on this Note shall be made to the applicable Depositary or its nominee, as the registered owner hereof. Unless otherwise specified on the face hereof or in the Final Terms, the first payment of interest on any Note originally issued between a Regular Record Date and an Interest Payment Date will be made on the Interest Payment Date following the next succeeding Regular Record Date to the registered owner on such next succeeding Regular Record Date. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the person in whose name this Note (or one or more predecessor Notes)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Each Bearer Security shall be dated the date from which any interest on the Securities of such series first begins to accrue and each Registered Security shall be dated the date of its authentication.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for below executed by the Trustee by manual, facsimile or electronic signature of one of its Responsible Officers, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder.

The Trustee's certificate of authentication shall be in substantially the following form:

(GLJ) has conducted a reserves audit of the proved reserves estimates of certain oil and gas properties owned by the United Mexican States. The effective date of the proved reserves is December 31, 2025 and the reserves audit was completed on February 11, 2026. The Company has represented that these properties account for 2.4 percent on a net oil equivalent barrel basis of the Company's net total proved reserves as of the effective date. There are 46 fields associated with the properties reviewed by GLJ, located within the Macuspana-Muspac and Cinco Presidentes business units. The estimates audited by GLJ were prepared by the Company in accordance with the reserves definitions of Regulation S-X Rule 4-10(a) of the U.S. Securities and Exchange Commission (SEC). GLJ's third party reserves audit was prepared for public disclosure by the Company in filings made with the SEC in accordance with the disclosure requirements set forth in the SEC regulations. According to the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (SPE auditing standards) published by the Society of Petroleum Engineers (2019), "An audit is an examination of Reserves information that is conducted for the purpose of expressing an opinion as to whether such Reserves information, in the aggregate, is reasonable and has been estimated by qualified individuals and presented in conformity with generally accepted petroleum engineering and evaluation principles and in compliance with the relevant Reserves definitions". Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. All reserves estimates involve some degree of uncertainty. The uncertainty depends chiefly on the amount of reliable geologic and engineering data available at the time of the estimate and the interpretation of these data. The relative degree of uncertainty may be conveyed by placing reserves into one of two principal classifications, either proved or unproved. Unproved reserves are less certain to be recovered than proved reserves and may be further sub- classified as probable and possible reserves to denote progressively increasing uncertainty in their recoverability. At the Company's request, this report addresses only the proved reserves attributable to the properties reviewed herein. 1920, 401 – 9th Ave SW Calgary, AB, Canada T2P 3C5 \| tel 403-266-9500 \| gljpc.com Exhibit 15.1 (Part 1 of 3) The Company provided a table with their reserves estimates by field and all pertinent well and reservoir data such as geological maps, well logs, production and injection history, drill stem tests, workovers, pressure surveys, production tests, fluid analysis, and planned development activities. The proved reserves prepared by the Company for the properties that GLJ reviewed were estimated based on volumetric calculations, decline analysis or material balance methods, or by any combination of the aforementioned methods depending on the available data and the significance of the property within the overall corporate portfolio. The economic parameters such as operating costs, capital costs, process losses, liquid yields, abandonment cost and product pricing provided by the Company were accepted by GLJ without review or verification. Prices, operating and capital costs, including maintenance capital, were provided by the Company. 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 effective date estimated reserves. GLJ has used all assumptions, data, procedures, and methods that it considers necessary and appropriate to prepare this report. For significant properties with performance-based assignments, GLJ reviewed the volumetric recovery to address the reasonableness of the assignment and development activity considered by the Company. In fields with significant performance and pressure data, the Company maps and geological models were accepted, but in cases where volumetric analysis formed the primary basis for the Company's reserves estimate, GLJ audited Company maps in more detail, including a review of associated geophysical interpretations. Based on our review, including the data, technical processes and interpretations presented by the Company, it is our opinion that the overall procedures and methodologies utilized by the Company in preparing their estimates of the proved reserves as of December 31, 2025 comply with the current SEC regulations, and that the overall proved reserves for the reviewed properties as estimated by the Company are, in the aggregate, reasonable within the established audit tolerance guidelines of 10 percent set forth in the SPE auditing standards. As in all aspects of oil and gas evaluation, there are uncertainties inherent in the interpretation of engineering and geoscience data; therefore, our conclusions necessarily represent only informed professional judgment. It is trusted that this audit meets your current requirements. Should you have any questions regarding this analysis, please contact the undersigned. Yours truly, GLJ LTD.

Based on our review, including the data, technical processes and interpretations presented by the Company, it is our opinion that the overall procedures and methodologies utilized by the Company in preparing their estimates of the proved reserves as of December 31, 2025 comply with the current SEC regulations, and that the overall proved reserves for the reviewed properties as estimated by the Company are, in the aggregate, reasonable within the established audit tolerance guidelines of 10 percent set forth in the SPE auditing standards. As in all aspects of oil and gas evaluation, there are uncertainties inherent in the interpretation of engineering and geoscience data; therefore, our conclusions necessarily represent only informed professional judgment. It is trusted that this audit meets your current requirements. Should you have any questions regarding this analysis, please contact the undersigned. Yours truly, GLJ LTD. Patrick A. Olenick, P. Eng.

(GLJ) has conducted a reserves audit of the proved reserves estimates of certain oil and gas properties owned by the United Mexican States. The effective date of the proved reserves is December 31, 2025 and the reserves audit was completed on February 12, 2026. The Company has represented that these properties account for 32.2 percent on a net oil equivalent barrel basis of the Company's net total proved reserves as of the effective date. There are 18 fields associated with the properties reviewed by GLJ, located within the Cantarell and Ku-Maloob-Zaap business units. The estimates audited by GLJ were prepared by the Company in accordance with the reserves definitions of Regulation S-X Rule 4-10(a) of the U.S. Securities and Exchange Commission (SEC). GLJ's third party reserves audit was prepared for public disclosure by the Company in filings made with the SEC in accordance with the disclosure requirements set forth in the SEC regulations. According to the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (SPE auditing standards) published by the Society of Petroleum Engineers (2019), "An audit is an examination of Reserves information that is conducted for the purpose of expressing an opinion as to whether such Reserves information, in the aggregate, is reasonable and has been estimated by qualified individuals and presented in conformity with generally accepted petroleum engineering and evaluation principles and in compliance with the relevant Reserves definitions". Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. All reserves estimates involve some degree of uncertainty. The uncertainty depends chiefly on the amount of reliable geologic and engineering data available at the time of the estimate and the interpretation of these data. The relative degree of uncertainty may be conveyed by placing reserves into one of two principal classifications, either proved or unproved. Unproved reserves are less certain to be recovered than proved reserves and may be further sub- classified as probable and possible reserves to denote progressively increasing uncertainty in their recoverability. At the Company's request, this report addresses only the proved reserves attributable to the properties reviewed herein. 1920, 401 – 9th Ave SW Calgary, AB, Canada T2P 3C5 \| tel 403-266-9500 \| gljpc.com Exhibit 15.1 (Part 3 of 3) The Company provided a table with their reserves estimates by field and all pertinent well and reservoir data such as geological maps, simulation models, well logs, production and injection history, drill stem tests, workovers, pressure surveys, production tests, fluid analysis, and planned development activities. The proved reserves prepared by the Company for the properties that GLJ reviewed were estimated based on volumetric calculations, decline analysis or material balance methods, and through a review of reservoir simulation models prepared by the Company, or by any combination of the aforementioned methods depending on the available data and the significance of the property within the overall corporate portfolio.

INDEPENDENT PETROLEUM CONSULTANTS' CONSENT The undersigned firm of Independent Petroleum Consultants of Calgary, Alberta, Canada has prepared an audit of Petróleos Mexicanos (the "Company") Mexican oil and gas properties within in Activo de Extracción Macuspana-Muspac y Activo de Extracción Cinco Presidentes, and hereby gives consent to the use of its name. In the course of the audit, the Company provided GLJ Ltd. personnel with basic information which included land data, well information, geological information, reservoir studies, estimates of on-stream dates, contract information, current hydrocarbon product prices, operating cost data, capital budget forecasts, financial data and future operating plans. According to the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (SPE auditing standards) published by the Society of Petroleum Engineers (2019), "An audit is an examination of Reserves information that is conducted for the purpose of expressing an opinion as to whether such Reserves information, in the aggregate, is reasonable and has been estimated by qualified individuals and presented in conformity with generally accepted petroleum engineering and evaluation principles and in compliance with the relevant Reserves definitions". Based on our review, including the data, technical processes and interpretations presented by the Company, it is our opinion that the overall procedures and methodologies utilized by the Company in preparing their estimates of the proved reserves as of December 31, 2025 comply with the current SEC regulations, and that the overall proved reserves for the reviewed properties as estimated by the Company are, in the aggregate, reasonable within the established audit tolerance guidelines of 10 percent set forth in the SPE auditing standards. Michael Livingstone, P.Geo. Senior Vice President April 17, 2026 John Martinez, P.Eng. Senior Engineer April 17, 2026 PERMIT TO PRACTICE GLJ LTD. RM Signature: RM APEGA ID#: 55083 Date: April 17, 2026 PERMIT NUMBER: P 2066 The Association of Professional Engineers and Geoscientists of Alberta (APEGA) Page: 5 of 17 INTRODUCTION GLJ Ltd. (GLJ) was commissioned by Petróleos Mexicanos (the "Company"), to prepare a reserves audit of the gross (100 percent) proved (1P) reserves and net gas reserves in 46 fields in Activo de Extracción Macuspana-Muspac y Activo de Extracción Cinco Presidentes. The effective date of the reserves estimates is December 31, 2025 and the reserves audit was completed on February 11, 2026. The Political Constitution of the United Mexican States provides that the Mexican nation owns all petroleum and other hydrocarbon reserves for these fields; however, these fields have been assigned to and are currently operated by the Company. The estimates audited by GLJ were prepared by the Company based on the definitions and disclosure guidelines of the United States Securities and Exchange Commission contained in the Title 17, Code of Federal Regulations, Modernization of Oil and Gas Reporting, Final Rule released January 14, 2009, in the Federal Register (SEC regulations). GLJ's third party reserves audit was prepared for public disclosure by the Company in filings made with the SEC in accordance with the disclosure requirements set forth in the SEC regulations. According to the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (SPE auditing standards) published by the Society of Petroleum Engineers (2019), "A Reserves audit is the process of reviewing certain of the pertinent facts interpreted and assumptions made that have resulted in an estimate of Reserves and/or Reserves information prepared by others and the rendering of an opinion about the appropriateness of the methodologies used, the adequacy and quality of the data relied upon, the depth and thoroughness of the Reserves estimation process, the categorization of Reserves appropriate to the relevant definitions used, and the reasonableness of the estimated Reserves quantities and/or the Reserves information." (section 2.2 (g)). Reserves Information may consist of various estimates pertaining to the extent and value of petroleum properties. Based on our review, including the data, technical processes and interpretations presented by the Company, it is our opinion that the overall procedures and methodologies utilized by the Company in preparing their estimates of the proved reserves as of December 31, 2025 comply with the current SEC regulations, and that the overall proved reserves for the reviewed properties as estimated by the Company are, in the aggregate, reasonable within the established audit tolerance guidelines of 10 percent set forth in the SPE auditing standards. For the reserves and income projections, the Company stated they used unweighted arithmetic average prices in effect at the first day of the month during the 12-month period prior to December 31, 2025 (the effective date), unless prices were defined by contractual arrangements, as required by the SEC regulations. Reserves were estimated by the Company to the economic limit of production. The following table sets forth the total proved net after royalty reserves under constant prices and costs as estimated by the Company attributable to the properties that GLJ reviewed: Page: 6 of 17 Notes (1) Oil is produced oil and liquids separated from gas in the field (2) Gross Gas is gas produced before any losses for fuel use, venting, transporting or plant shrinkage, net of re-injection (3) Plant Inlet Gas is gas volumes measured at plant inlet, that is, gas in the reservoirs to be produced after shrinkage resulting from field separation and flaring, net of re-injection (4) Condensate is the liquid volume recovered from the gas stream during the compression and dehydration stages of processing (5) Plant liquids are liquid volumes recovered from the gas stream through the processing plants (6) Dry Gas is gas after sweetening and removal of condensate and plant liquids and adjustment for re-injection and fuel losses. Units in barrels of oil equivalent using gas conversion factors provided by the Company (7) Barrels of oil equivalent were estimated assuming property specific ratio based on sales gas heating values provided by the Company Liquid hydrocarbons are expressed in millions of barrels (MMbbl) and gas volumes are expressed in billions of cubic feet (MMMcf) at the official temperature and pressure bases of the areas in which the gas reserves are located. The net remaining reserves are also shown herein on an equivalent unit (boe) basis wherein natural gas is converted to oil equivalent barrels using a specific factor for each field. MMboe represents million barrels of oil equivalent. GLJ notes that the Company has represented that its management of the produced fluids ends at the inlet of the gas processing plants. The reserves estimates include estimates of oil, plant condensate, plant inlet gas, sales gas, natural gas liquids and oil equivalent totals. As the Company has represented that all subsurface hydrocarbons belong to the United Mexican States and given that the Company has also represented that it has been assigned a 100 percent interest in the audited properties by the United Mexican States, gross and net reserves are equal. The Audit Procedure section outlines general procedures used in preparing this audit.

Portions of these definitions within square parentheses, [ ], have been transposed from other sections of Regulation S-X 210.4-10 to improve readability. Resources Resources are quantities of oil and gas estimated to exist in naturally occurring accumulations. A portion of the resources may be estimated to be recoverable, and another portion may be considered to be unrecoverable. Resources include both discovered and undiscovered accumulations. Reserves Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering oil and gas or related substances to market, and all permits and financing required to implement the project. Note: Reserves should not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that are clearly separated from a known accumulation by a non-productive reservoir (i.e. , absence of reservoir, structurally low reservoir, or negative test results). Such areas may contain prospective resources (i.e., potentially recoverable resources from undiscovered accumulations). 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 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. Page: 8 of 17

![](exhibit152reportsonreser003.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 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. Page: 9 of 17 (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 [see Other Definitions below], or by other evidence using reliable technology establishing reasonable certainty. OTHER PERTINENT DEFINITIONS Analogous Reservoir Analogous reservoirs, as used in resources assessments, have similar rock and fluid properties, reservoir conditions (depth, temperature, and pressure) and drive mechanisms, but are typically at a more advanced stage of development than the reservoir of interest and thus may provide concepts to assist in the interpretation of more limited data and estimation of recovery. When used to support proved reserves, an "analogous reservoir" refers to a reservoir that shares the following characteristics with the reservoir of interest: (i) Same geological formation (but not necessarily in pressure communication with the reservoir of interest); (ii) Same environment of deposition; (iii) Similar geological structure; and (iv) Same drive mechanism. Reasonable Certainty If deterministic methods are used, reasonable certainty means a high degree of confidence that the quantities will be recovered. If probabilistic methods are used, there should be at least a 90% probability that the quantities actually recovered will equal or exceed the estimate. A high degree of confidence exists if the quantity is much more likely to be achieved than not, and, as changes due to increased availability of geoscience (geological, geophysical, and geochemical), engineering, and economic data are made to estimated ultimate recovery (EUR) with time, reasonably certain EUR is much more likely to increase or remain constant than to decrease. Reliable Technology Reliable technology is a grouping of one or more technologies (including computational methods) that has been field tested and has been demonstrated to provide reasonably certain results with consistency and repeatability in the formation being evaluated or in an analogous formation. Reservoir A porous and permeable underground formation containing a natural accumulation of producible oil and/or gas that is confined by impermeable rock or water barriers and is individual and separate from other reservoirs. Page: 10 of 17 AUDIT PROCEDURE The following outlines the methodology employed by GLJ Ltd. (GLJ) in conducting the audit of the Company's oil and gas properties. GLJ evaluation procedures are in compliance with standards and guidelines contained with the Society of Petroleum Engineers (SPE) Petroleum Resources Management System (PRMS) INTEREST DESCRIPTIONS The Company provided GLJ with current land interest information. The Company has represented that all subsurface hydrocarbons belong to the United Mexican States, and that the Company has been assigned a 100 percent interest in the audited properties by the United Mexican States; therefore, gross and net reserves are equal. The cash flow and production forecasts were limited by economic limits not by a lease expiry. DATA PROVIDED The company provided a table with their reserves estimates by field. Additionally, all pertinent well, reservoir and economic data such as geological maps, well logs, production and injection history, drill stem tests, workovers, pressure surveys, production tests, fluid analysis, planned development activities, operating expenses, capital costs, abandonment cost, process losses, liquid yields, etc., were provided by the Company. TECHNICAL REVIEW GLJ performs a bottoms-up analysis where individual properties are audited. Auditors review historical production, well activity, mapping, pressure data and development plans as well as the evaluation approach used by the Company. Meetings with the Company were held to determine the Company's view of the reservoirs and technical justification for future development. The reserves estimates prepared by the Company for the properties that GLJ reviewed were estimated based on volumetric calculations, decline analysis or material balance methods or by any combination of the aforementioned methods depending on the available data and the significance of the property within the overall corporate portfolio. Where possible, performance-based reserve assignments were made by the Company. For significant properties with performance based assignments, GLJ reviewed the volumetric recovery to address the reasonableness of the assignment and development activity considered by the Company. In fields with significant performance and pressure data, the Company maps and geological models were accepted, but in cases where volumetric analysis formed the primary basis for the Company's reserves estimate, GLJ audited Company maps in more detail, including a review of associated geophysical interpretations. Data used in the audit were obtained from Company personnel and Company files. In the preparation of our report GLJ accepted as presented, and have relied, without independent verification, upon a variety of information furnished by the Company such as interests and burdens, production, product transportation and marketing and sales agreements, capital costs, operating expense data, and capital cost estimates. If, in the course of the audit, the validity or sufficiency of any material information was brought into question, GLJ did not rely on such information until such concerns were satisfactorily resolved. Page: 11 of 17 The economic parameters such as operating costs, capital costs, process losses, liquid yields, abandonment cost and product pricing provided by the Company were accepted by GLJ without review or verification. Prices, operating and capital costs, including maintenance capital, were provided by the Company. Reserves were estimated by the Company to the economic limit of production. MARKETABLE PRODUCTS Recoverable reserves were estimated by the Company to the following products: Oil Produced oil and liquids separated from gas in the field Condensate Condensate is the liquid volume recovered from the gas stream during the compression and dehydration stages of processing Plant Liquids Plant liquids are liquid volumes recovered from the gas stream through the processing plants Plant Inlet Gas Gas volumes measured at plant inlet, that is, gas in the reservoirs to be produced after shrinkage resulting from field separation and flaring, net of re-injection Dry Gas Gas after sweetening and removal of condensate and plant liquids and adjustment for re-injection and fuel losses GLJ notes that the Company has represented to GLJ that its management of the produced fluids ends at the inlet of the gas processing plants. The Company also presented quantities of hydrocarbons in barrels of oil equivalent (boe) using their own conversion factors.

(GLJ) has conducted a reserves audit of the proved reserves estimates of certain oil and gas properties owned by the United Mexican States. The effective date of the proved reserves is December 31, 2025 and the reserves audit was completed on February 13, 2026. The Company has represented that these properties account for 22.9 percent on a net oil equivalent barrel basis of the Company's net total proved reserves as of the effective date. There are 139 fields associated with the properties reviewed by GLJ, located within the Reynosa and Veracruz business units. The estimates audited by GLJ were prepared by the Company in accordance with the reserves definitions of Regulation S-X Rule 4-10(a) of the U.S. Securities and Exchange Commission (SEC). GLJ's third party reserves audit was prepared for public disclosure by the Company in filings made with the SEC in accordance with the disclosure requirements set forth in the SEC regulations. According to the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (SPE auditing standards) published by the Society of Petroleum Engineers (2019), "An audit is an examination of Reserves information that is conducted for the purpose of expressing an opinion as to whether such Reserves information, in the aggregate, is reasonable and has been estimated by qualified individuals and presented in conformity with generally accepted petroleum engineering and evaluation principles and in compliance with the relevant Reserves definitions". Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. All reserves estimates involve some degree of uncertainty. The uncertainty depends chiefly on the amount of reliable geologic and engineering data available at the time of the estimate and the interpretation of these data. The relative degree of uncertainty may be conveyed by placing reserves into one of two principal classifications, either proved or unproved. Unproved reserves are less certain to be recovered than proved reserves and may be further sub- classified as probable and possible reserves to denote progressively increasing uncertainty in their recoverability. At the Company's request, this report addresses only the proved reserves attributable to the properties reviewed herein. 1920, 401 – 9th Ave SW Calgary, AB, Canada T2P 3C5 \| tel 403-266-9500 \| gljpc.com

The Company provided a table with their reserves estimates by field and all pertinent well and reservoir data such as geological maps, well logs, production and injection history, drill stem tests, workovers, pressure surveys, production tests, fluid analysis, and planned development activities. The proved reserves prepared by the Company for the properties that GLJ reviewed were estimated based on volumetric calculations, decline analysis or material balance methods, and through a review of reservoir simulation models prepared by the Company, or by any combination of the aforementioned methods depending on the available data and the significance of the property within the overall corporate portfolio. The economic parameters such as operating costs, capital costs, process losses, liquid yields, abandonment cost and product pricing provided by the Company were accepted by GLJ without review or verification. Prices, operating and capital costs, including maintenance capital, were provided by the Company. 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 effective date estimated reserves. GLJ has used all assumptions, data, procedures, and methods that it considers necessary and appropriate to prepare this report. For significant properties with performance-based assignments, GLJ reviewed the volumetric recovery to address the reasonableness of the assignment and development activity considered by the Company. In fields with significant performance and pressure data, the Company maps and geological models were accepted, but in cases where volumetric analysis formed the primary basis for the Company's reserves estimate, GLJ audited Company maps in more detail, including a review of associated geophysical interpretations. Based on our review, including the data, technical processes and interpretations presented by the Company, it is our opinion that the overall procedures and methodologies utilized by the Company in preparing their estimates of the proved reserves as of December 31, 2025 comply with the current SEC regulations, and that the overall proved reserves for the reviewed properties as estimated by the Company are, in the aggregate, reasonable within the established audit tolerance guidelines of 10 percent set forth in the SPE auditing standards. As in all aspects of oil and gas evaluation, there are uncertainties inherent in the interpretation of engineering and geoscience data; therefore, our conclusions necessarily represent only informed professional judgment. It is trusted that this audit meets your current requirements. Should you have any questions regarding this analysis, please contact the undersigned. Yours truly, GLJ LTD. Patrick A. Olenick, P. Eng.

RM Signature: RM APEGA ID#: 55083 Date: April 17, 2026 PERMIT NUMBER: P 2066 The Association of Professional Engineers and Geoscientists of Alberta (APEGA) Page: 5 of 16 INTRODUCTION GLJ Ltd. (GLJ) was commissioned by Petroleos Mexicanos (the "Company"), to prepare a reserves audit of the gross (100 percent) proved (1P) reserves and net gas reserves in 139 fields in Activo de Extracción Reynosa y Activo de Extracción Veracruz. The effective date of the reserves estimates is December 31, 2025 and the reserves audit was completed on February 13, 2026. The Political Constitution of the United Mexican States provides that the Mexican nation owns all petroleum and other hydrocarbon reserves for these fields; however, these fields have been assigned to and are currently operated by the Company. The estimates audited by GLJ were prepared by the Company based on the definitions and disclosure guidelines of the United States Securities and Exchange Commission contained in the Title 17, Code of Federal Regulations, Modernization of Oil and Gas Reporting, Final Rule released January 14, 2009, in the Federal Register (SEC regulations). GLJ's third party reserves audit was prepared for public disclosure by the Company in filings made with the SEC in accordance with the disclosure requirements set forth in the SEC regulations. According to the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (SPE auditing standards) published by the Society of Petroleum Engineers (2019), "A Reserves audit is the process of reviewing certain of the pertinent facts interpreted and assumptions made that have resulted in an estimate of Reserves and/or Reserves information prepared by others and the rendering of an opinion about the appropriateness of the methodologies used, the adequacy and quality of the data relied upon, the depth and thoroughness of the Reserves estimation process, the categorization of Reserves appropriate to the relevant definitions used, and the reasonableness of the estimated Reserves quantities and/or the Reserves information." (section 2.2 (g)). Reserves Information may consist of various estimates pertaining to the extent and value of petroleum properties. Based on our review, including the data, technical processes and interpretations presented by the Company, it is our opinion that the overall procedures and methodologies utilized by the Company in preparing their estimates of the proved reserves as of December 31, 2025 comply with the current SEC regulations, and that the overall proved reserves for the reviewed properties as estimated by the Company are, in the aggregate, reasonable within the established audit tolerance guidelines of 10 percent set forth in the SPE auditing standards. For the reserves and income projections, the Company stated they used unweighted arithmetic average prices in effect at the first day of the month during the 12-month period prior to December 31, 2025 (the effective date), unless prices were defined by contractual arrangements, as required by the SEC regulations. Reserves were estimated by the Company to the economic limit of production. The following table sets forth the total proved net after royalty reserves under constant prices and costs as estimated by the Company attributable to the properties that GLJ reviewed: Page: 6 of 16 Notes: (1) Oil is produced oil and liquids separated from gas in the field (2) Gross Gas is gas produced before any losses for fuel use, venting, transporting or plant shrinkage, net of re-injection (3) Plant Inlet Gas is gas volumes measured at plant inlet, that is, gas in the reservoirs to be produced after shrinkage resulting from field separation and flaring, net of re-injection (4) Condensate is the liquid volume recovered from the gas stream during the compression and dehydration stages of processing (5) Plant liquids are liquid volumes recovered from the gas stream through the processing plants (6) Dry Gas is gas after sweetening and removal of condensate and plant liquids and adjustment for re-injection and fuel losses. Units in barrels of oil equivalent using gas conversion factors provided by the Company (7) Barrels of oil equivalent were estimated assuming property specific ratio based on sales gas heating values provided by the Company Liquid hydrocarbons are expressed in millions of barrels (MMbbl) and gas volumes are expressed in billions of cubic feet (MMMcf) at the official temperature and pressure bases of the areas in which the gas reserves are located. The net remaining reserves are also shown herein on an equivalent unit (boe) basis wherein natural gas is converted to oil equivalent barrels using a specific factor for each field. MMboe represents million barrels of oil equivalent. GLJ notes that the Company has represented that its management of the produced fluids ends at the inlet of the gas processing plants. The reserves include estimates of oil, plant condensate, plant inlet gas, sales gas, natural gas liquids and oil equivalent totals. As the Company has represented that all subsurface hydrocarbons belong to the United Mexican States and given that the Company has also represented that it has been assigned a 100 percent interest in the audited properties by the United Mexican States, gross and net reserves are equal. The Audit Procedure section outlines general procedures used in preparing this audit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;SEC RESERVES DEFINITIONS The following definitions are excerpts from Regulation S-X 210.4-10. Portions of these definitions within square parentheses, [ ], have been transposed from other sections of Regulation S-X 210.4-10 to improve readability. Resources Resources are quantities of oil and gas estimated to exist in naturally occurring accumulations. A portion of the resources may be estimated to be recoverable, and another portion may be considered to be unrecoverable. Resources include both discovered and undiscovered accumulations. Reserves Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering oil and gas or related substances to market, and all permits and financing required to implement the project. Note: Reserves should not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that are clearly separated from a known accumulation by a non-productive reservoir (i.e. , absence of reservoir, structurally low reservoir, or negative test results). Such areas may contain prospective resources (i.e., potentially recoverable resources from undiscovered accumulations). 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 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. Page: 8 of 16 (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 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. Page: 9 of 16 (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 [see Other Definitions below], or by other evidence using reliable technology establishing reasonable certainty. OTHER PERTINENT DEFINITIONS Analogous Reservoir Analogous reservoirs, as used in resources assessments, have similar rock and fluid properties, reservoir conditions (depth, temperature, and pressure) and drive mechanisms, but are typically at a more advanced stage of development than the reservoir of interest and thus may provide concepts to assist in the interpretation of more limited data and estimation of recovery. When used to support proved reserves, an "analogous reservoir" refers to a reservoir that shares the following characteristics with the reservoir of interest: (i) Same geological formation (but not necessarily in pressure communication with the reservoir of interest); (ii) Same environment of deposition; (iii) Similar geological structure; and (iv) Same drive mechanism. Reasonable Certainty If deterministic methods are used, reasonable certainty means a high degree of confidence that the quantities will be recovered. If probabilistic methods are used, there should be at least a 90% probability that the quantities actually recovered will equal or exceed the estimate. A high degree of confidence exists if the quantity is much more likely to be achieved than not, and, as changes due to increased availability of geoscience (geological, geophysical, and geochemical), engineering, and economic data are made to estimated ultimate recovery (EUR) with time, reasonably certain EUR is much more likely to increase or remain constant than to decrease. Reliable Technology Reliable technology is a grouping of one or more technologies (including computational methods) that has been field tested and has been demonstrated to provide reasonably certain results with consistency and repeatability in the formation being evaluated or in an analogous formation. Reservoir A porous and permeable underground formation containing a natural accumulation of producible oil and/or gas that is confined by impermeable rock or water barriers and is individual and separate from other reservoirs. Page: 10 of 16 AUDIT PROCEDURE The following outlines the methodology employed by GLJ Ltd. (GLJ) in conducting the evaluation of the Company's oil and gas properties. GLJ evaluation procedures are in compliance with standards and guidelines contained with the Society of Petroleum Engineers (SPE) Petroleum Resources Management System (PRMS) INTEREST DESCRIPTIONS The Company provided GLJ with current land interest information. The Company has represented that all subsurface hydrocarbons belong to the United Mexican States, and that the Company has been assigned a 100 percent interest in the audited properties by the United Mexican States; therefore, gross and net reserves are equal. The cash flow and production forecasts were limited by economic limits not by a lease expiry. DATA PROVIDED The company provided a table with their reserves estimates by field. Additionally, all pertinent well, reservoir and economic data such as geological maps, well logs, production and injection history, drill stem tests, workovers, pressure surveys, production tests, fluid analysis, planned development activities, operating expenses, capital costs, abandonment cost, process losses, liquid yields, etc., were provided by the Company. TECHNICAL REVIEW GLJ performs a bottoms-up analysis where individual properties are audited. Auditors review historical production, well activity, mapping, pressure data and development plans as well as the evaluation approach used by the Company. Meetings with the Company were held to determine the Company's view of the reservoirs and technical justification for future development. The reserves estimates prepared by the Company for the properties that GLJ reviewed were estimated based on volumetric calculations, decline analysis or material balance methods or by any combination of the aforementioned methods depending on the available data and the significance of the property within the overall corporate portfolio. Where possible, performance-based reserve assignments were made by the Company. For significant properties with performance-based assignments, GLJ reviewed the volumetric recovery to address the reasonableness of the assignment and development activity considered by the Company. In fields with significant performance and pressure data, the Company maps and geological models were accepted, but in cases where volumetric analysis formed the primary basis for the Company's reserves estimate, GLJ audited Company maps in more detail, including a review of associated geophysical interpretations. Data used in the audit were obtained from Company personnel and Company files. In the preparation of our report GLJ accepted as presented, and have relied, without independent verification, upon a variety of information furnished by the Company such as interests and burdens, production, product transportation and marketing and sales agreements, capital costs, operating expense data, and capital cost estimates. If, in the course of the audit, the validity or sufficiency of any material information was brought into question, GLJ did not rely on such information until such concerns were satisfactorily resolved.

The economic parameters such as operating costs, capital costs, process losses, liquid yields, abandonment cost and product pricing provided by the Company were accepted by GLJ without review or verification. Prices, operating and capital costs, including maintenance capital, were provided by the Company. Reserves were estimated by the Company to the economic limit of production. MARKETABLE PRODUCTS Recoverable reserves were estimated by the Company to the following products: Oil Produced oil and liquids separated from gas in the field Condensate Condensate is the liquid volume recovered from the gas stream during the compression and dehydration stages of processing Plant Liquids Plant liquids are liquid volumes recovered from the gas stream through the processing plants Plant Inlet Gas Gas volumes measured at plant inlet, that is, gas in the reservoirs to be produced after shrinkage resulting from field separation and flaring, net of re-injection Dry Gas Gas after sweetening and removal of condensate and plant liquids and adjustment for re-injection and fuel losses GLJ notes that the Company has represented to GLJ that its management of the produced fluids ends at the inlet of the gas processing plants. The Company also presented quantities of hydrocarbons in barrels of oil equivalent (boe) using their own conversion factors.

(GLJ) has conducted a reserves audit of the proved reserves estimates of certain oil and gas properties owned by the United Mexican States. The effective date of the proved reserves is December 31, 2025 and the reserves audit was completed on February 12, 2026. The Company has represented that these properties account for 32.2 percent on a net oil equivalent barrel basis of the Company's net total proved reserves as of the effective date. There are 18 fields associated with the properties reviewed by GLJ, located within the Cantarell and Ku-Maloob-Zaap business units. The estimates audited by GLJ were prepared by the Company in accordance with the reserves definitions of Regulation S-X Rule 4-10(a) of the U.S. Securities and Exchange Commission (SEC). GLJ's third party reserves audit was prepared for public disclosure by the Company in filings made with the SEC in accordance with the disclosure requirements set forth in the SEC regulations.

The Company provided a table with their reserves estimates by field and all pertinent well and reservoir data such as geological maps, simulation models, well logs, production and injection history, drill stem tests, workovers, pressure surveys, production tests, fluid analysis, and planned development activities. The proved reserves prepared by the Company for the properties that GLJ reviewed were estimated based on volumetric calculations, decline analysis or material balance methods, and through a review of reservoir simulation models prepared by the Company, or by any combination of the aforementioned methods depending on the available data and the significance of the property within the overall corporate portfolio. The economic parameters such as operating costs, capital costs, process losses, liquid yields, abandonment cost and product pricing provided by the Company were accepted by GLJ without review or verification. Prices, operating and capital costs, including maintenance capital, were provided by the Company. 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 effective date estimated reserves. GLJ has used all assumptions, data, procedures, and methods that it considers necessary and appropriate to prepare this report. For significant properties with performance-based assignments, GLJ reviewed the volumetric recovery to address the reasonableness of the assignment and development activity considered by the Company. In fields with significant performance and pressure data, the Company maps and geological models were accepted, but in cases where volumetric analysis formed the primary basis for the Company's reserves estimate, GLJ audited Company maps in more detail, including a review of associated geophysical interpretations. Based on our review, including the data, technical processes and interpretations presented by the Company, it is our opinion that the overall procedures and methodologies utilized by the Company in preparing their estimates of the proved reserves as of December 31, 2025 comply with the current SEC regulations, and that the overall proved reserves for the reviewed properties as estimated by the Company are, in the aggregate, reasonable within the established audit tolerance guidelines of 10 percent set forth in the SPE auditing standards. As in all aspects of oil and gas evaluation, there are uncertainties inherent in the interpretation of engineering and geoscience data; therefore, our conclusions necessarily represent only informed professional judgment.

Michael Livingstone, P.Geo. Senior Vice President April 17, 2026 Julisa Rocabado, P.Eng. Senior Engineer April 17 2026 PERMIT TO PRACTICE GLJ LTD. RM Signature:_________________________ RM APEGA ID#: 73297 Date: April 17, 2026 PERMIT NUMBER: P 2066 The Association of Professional Engineers and Geoscientists of Alberta (APEGA) Page: 5 of 17 INTRODUCTION GLJ Ltd. (GLJ) was commissioned by Petróleos Mexicanos (the "Company"), to prepare a reserves audit of the gross (100 percent working interest) proved reserves and net gas reserves in 18 fields in the Activo de Extracción Cantarell and Activo de Extracción Ku-Maloob-Zaap. The effective date of the proved reserves is December 31, 2025 and the reserves audit was completed on February 12, 2026. The Political Constitution of the United Mexican States provides that the Mexican nation owns all petroleum and other hydrocarbon reserves for these fields; however, these fields have been assigned to and are currently operated by the Company. The estimates audited by GLJ were prepared by the Company based on the definitions and disclosure guidelines of the United States Securities and Exchange Commission contained in the Title 17, Code of Federal Regulations, Modernization of Oil and Gas Reporting, Final Rule released January 14, 2009, in the Federal Register (SEC regulations). GLJ's third party reserves audit was prepared for public disclosure by the Company in filings made with the SEC in accordance with the disclosure requirements set forth in the SEC regulations. According to the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (SPE auditing standards) published by the Society of Petroleum Engineers (2019), "A Reserves audit is the process of reviewing certain of the pertinent facts interpreted and assumptions made that have resulted in an estimate of Reserves and/or Reserves information prepared by others and the rendering of an opinion about the appropriateness of the methodologies used, the adequacy and quality of the data relied upon, the depth and thoroughness of the Reserves estimation process, the categorization of Reserves appropriate to the relevant definitions used, and the reasonableness of the estimated Reserves quantities and/or the Reserves information." (section 2.2 (g)). Reserves Information may consist of various estimates pertaining to the extent and value of petroleum properties. Based on our review, including the data, technical processes and interpretations presented by the Company, it is our opinion that the overall procedures and methodologies utilized by the Company in preparing their estimates of the proved reserves as of December 31, 2025 comply with the current SEC regulations, and that the overall proved reserves for the reviewed properties as estimated by the Company are, in the aggregate, reasonable within the established audit tolerance guidelines of 10 percent set forth in the SPE auditing standards. For the reserves and income projections, the Company stated they used unweighted arithmetic average prices in effect at the first day of the month during the 12-month period prior to December 31, 2025 (the effective date), unless prices were defined by contractual arrangements, as required by the SEC regulations. Reserves were estimated by the Company to the economic limit of production. The following table sets forth the total proved net after royalty reserves under constant prices and costs as estimated by the Company attributable to the properties that GLJ reviewed: Page: 6 of 17 (1) Oil is produced oil and liquids separated from gas in the field (2) Gross Gas is gas produced before any losses for fuel use, venting, transporting or plant shrinkage, net of re-injection (3) Plant Inlet Gas is gas volumes measured at plant inlet, that is, gas in the reservoirs to be produced after shrinkage resulting from field separation and flaring, net of re-injection (4) Condensate is the liquid volume recovered from the gas stream during the compression and dehydration stages of processing (5) Plant liquids are liquid volumes recovered from the gas stream through the processing plants (6) Dry Gas is gas after sweetening and removal of condensate and plant liquids and adjustment for re-injection and fuel losses. Units in barrels of oil equivalent using gas conversion factors provided by the Company (7) Barrels of oil equivalent were estimated assuming property specific ratio based on sales gas heating values provided by the Company Liquid hydrocarbons are expressed in millions of barrels (MMbbl) and gas volumes are expressed in billions of cubic feet (MMMcf) at the official temperature and pressure bases of the areas in which the gas reserves are located. The net remaining reserves are also shown herein on an equivalent unit (boe) basis wherein natural gas is converted to oil equivalent barrels using a specific factor for each field. MMboe represents million barrels of oil equivalent. GLJ notes that the Company has represented that its management of the produced fluids ends at the inlet of the gas processing plants. The reserves estimates include estimates of oil, plant condensate, plant inlet gas, sales gas, natural gas liquids and oil equivalent totals. As the Company has represented that all subsurface hydrocarbons belong to the United Mexican States and given that the Company has also represented that it has been assigned a 100 percent interest in the audited properties by the United Mexican States, gross and net reserves are equal. The Audit Procedure section outlines general procedures used in preparing this audit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;SEC RESERVES DEFINITIONS The following definitions are excerpts from Regulation S-X 210.4-10. Portions of these definitions within square parentheses, [ ], have been transposed from other sections of Regulation S-X 210.4-10 to improve readability. Resources Resources are quantities of oil and gas estimated to exist in naturally occurring accumulations. A portion of the resources may be estimated to be recoverable, and another portion may be considered to be unrecoverable. Resources include both discovered and undiscovered accumulations. Reserves Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering oil and gas or related substances to market, and all permits and financing required to implement the project. Note: Reserves should not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that are clearly separated from a known accumulation by a non-productive reservoir (i.e. , absence of reservoir, structurally low reservoir, or negative test results). Such areas may contain prospective resources (i.e., potentially recoverable resources from undiscovered accumulations). 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 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. Page: 8 of 17 (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 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. Page: 9 of 17 (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 [see Other Definitions below], or by other evidence using reliable technology establishing reasonable certainty. OTHER PERTINENT DEFINITIONS Analogous Reservoir Analogous reservoirs, as used in resources assessments, have similar rock and fluid properties, reservoir conditions (depth, temperature, and pressure) and drive mechanisms, but are typically at a more advanced stage of development than the reservoir of interest and thus may provide concepts to assist in the interpretation of more limited data and estimation of recovery. When used to support proved reserves, an "analogous reservoir" refers to a reservoir that shares the following characteristics with the reservoir of interest: (i) Same geological formation (but not necessarily in pressure communication with the reservoir of interest); (ii) Same environment of deposition; (iii) Similar geological structure; and (iv) Same drive mechanism. Reasonable Certainty If deterministic methods are used, reasonable certainty means a high degree of confidence that the quantities will be recovered. If probabilistic methods are used, there should be at least a 90% probability that the quantities actually recovered will equal or exceed the estimate. A high degree of confidence exists if the quantity is much more likely to be achieved than not, and, as changes due to increased availability of geoscience (geological, geophysical, and geochemical), engineering, and economic data are made to estimated ultimate recovery (EUR) with time, reasonably certain EUR is much more likely to increase or remain constant than to decrease. Reliable Technology Reliable technology is a grouping of one or more technologies (including computational methods) that has been field tested and has been demonstrated to provide reasonably certain results with consistency and repeatability in the formation being evaluated or in an analogous formation. Reservoir A porous and permeable underground formation containing a natural accumulation of producible oil and/or gas that is confined by impermeable rock or water barriers and is individual and separate from other reservoirs. Page: 10 of 17 AUDIT PROCEDURE The following outlines the methodology employed by GLJ Ltd. (GLJ) in conducting the audit of the Company's oil and gas properties. GLJ audit procedures are in compliance with standards and guidelines contained with the Society of Petroleum Engineers (SPE) Petroleum Resources Management System (PRMS) INTEREST DESCRIPTIONS The Company provided GLJ with current land interest information. The Company has represented that all subsurface hydrocarbons belong to the United Mexican States, and that the Company has been assigned a 100 percent interest in the audited properties by the United Mexican States; therefore, gross and net reserves are equal. The cash flow and production forecasts were limited by economic limits not by a lease expiry. DATA PROVIDED The company provided a table with their reserves estimates by field. Additionally, all pertinent well, reservoir and economic data such as geological maps, simulation models, well logs, production and injection history, drill stem tests, workovers, pressure surveys, production tests, fluid analysis, planned development activities, operating expenses, capital costs, abandonment cost, process losses, liquid yields, etc., were provided by the Company. TECHNICAL REVIEW GLJ performs a bottoms-up analysis where individual properties are audited. Auditors review historical production, well activity, mapping, pressure data and development plans as well as the evaluation approach used by the Company. Meetings with the Company were held to determine the Company's view of the reservoirs and technical justification for future development. The reserves estimates prepared by the Company for the properties that GLJ reviewed were estimated based on volumetric calculations, decline analysis, reservoir simulation or material balance methods or by any combination of the aforementioned methods depending on the available data and the significance of the property within the overall corporate portfolio. Where possible, performance-based reserve assignments were made by the Company. For significant properties with performance-based assignments, GLJ reviewed the volumetric recovery to address the reasonableness of the assignment and development activity considered by the Company. In fields with significant performance and pressure data, the Company maps and geological models were accepted, but in cases where volumetric analysis formed the primary basis for the Company's reserves estimate, GLJ audited Company maps in more detail, including a review of associated geophysical interpretations. Data used in the audit were obtained from Company personnel and Company files. In the preparation of our report GLJ accepted as presented, and have relied, without independent verification, upon a variety of information furnished by the Company such as interests and burdens, production, product transportation and marketing and sales agreements, capital costs, operating expense data, and capital cost estimates. If, in the course of the audit, the validity or sufficiency of any material information was brought into question, GLJ did not rely on such information until such concerns were satisfactorily resolved.

The economic parameters such as operating costs, capital costs, process losses, liquid yields, abandonment cost and product pricing provided by the Company were accepted by GLJ without review or verification. Prices, operating and capital costs, including maintenance capital, were provided by the Company. Reserves were estimated by the Company to the economic limit of production. MARKETABLE PRODUCTS Recoverable reserves were estimated by the Company to the following products: Oil Produced oil and liquids separated from gas in the field Condensate Condensate is the liquid volume recovered from the gas stream during the compression and dehydration stages of processing Plant Liquids Plant liquids are liquid volumes recovered from the gas stream through the processing plants Plant Inlet Gas Gas volumes measured at plant inlet, that is, gas in the reservoirs to be produced after shrinkage resulting from field separation and flaring, net of re-injection Dry Gas Gas after sweetening and removal of condensate and plant liquids and adjustment for re-injection and fuel losses GLJ notes that the Company has represented to GLJ that its management of the produced fluids ends at the inlet of the gas processing plants. The Company also presented quantities of hydrocarbons in barrels of oil equivalent (boe) using their own conversion factors.

DeGolyer and MacNaughton 5001 Spring Valley Road Suite 800 East Dallas, Texas 75244 This is a digital representation of a DeGolyer and MacNaughton report. This file is intended to be a manifestation of certain data in the subject report and as such is subject to the same conditions thereof. The information and data contained in this file may be subject to misinterpretation; therefore, the signed and bound copy of this report should be considered the only authoritative source of such information. Exhibit 15.4 DeGo l y e r a n d MacN augh ton 5001 Spring Valley Road Suite 800 East Dallas, Texas 75244 April 17, 2026 Dr. Víctor Rodríguez Padilla Director General de Petróleos Mexicanos Avenida Marina Nacional No. 329 Torre Ejecutiva, Piso 44 Colonia Verónica Anzures, C.P. 11300 Alcaldía Miguel Hidalgo Ciudad de Mexico, Mexico Dear Dr. Víctor Rodríguez Padilla: Pursuant to your request, this report of third party presents an independent evaluation, as of January 1, 2026, of the estimated net proved oil, condensate, gas, and oil equivalent reserves of certain properties that Dirección de Exploración y Extracción de Petróleos Mexicanos (DEE) has represented are owned by the United Mexican States. This evaluation was completed on April 17, 2026. These properties are located in the United Mexican States. DEE has represented that these properties account for 4.87 percent on a net oil equivalent barrel basis of DEE's net proved reserves as of January 1, 2026. We have reviewed information provided by DEE that it represents to be DEE's estimates of the net reserves, as of January 1, 2026, for the same properties as those which we evaluated. DEE has represented that its net proved reserves estimates were 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). It is our opinion that the procedures and methodologies employed by DEE for the preparation of its proved reserves estimates as of January 1, 2026, comply with the current requirements of the 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 DEE. DEE has represented that all subsurface hydrocarbons belong to the United Mexican States as stated in the Mexican Hydrocarbon Law (Ley de Hidrocarburos). DeGolyer and MacNaughton 2 At the request of DEE, this report also presents estimates prepared by DEE of its natural gas liquids (plant liquids) reserves; however, DEE has represented that its management of the properties stops at the inlet of the gas processing plants; therefore, DEE has no right to those quantities presented herein. Reserves estimates included herein are expressed as net reserves as represented by DEE. Gross reserves are defined as the total estimated petroleum remaining to be produced from these properties after December 31, 2025. Net reserves are defined as that portion of the gross reserves attributable to the interests owned by the United Mexican States and held by DEE after deducting all interests held by others, without consideration of royalties and other fiscal or contractual terms. 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 DEE. In the preparation of this report we have relied, without independent verification, upon information furnished by DEE 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. DeGolyer and MacNaughton 3 Definition of Reserves Petroleum reserves included 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 established 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 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,

------

![](exhibit154reportsonreser002.jpg)

DeGolyer and MacNaughton 4 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 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 DeGolyer and MacNaughton 5 (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 other evidence using reliable technology establishing reasonable certainty. DeGolyer and MacNaughton 6 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." 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 DEE, 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 DEE. DEE has represented that its senior management is committed to the development plan provided by DEE and that DEE has the financial capability to execute the development plan, including the drilling and completion of wells and the installation of equipment and facilities. When applicable, the volumetric method was used to estimate the original oil in place (OOIP) and original gas in place (OGIP). Structure maps were prepared to delineate each reservoir, and isopach maps were constructed to estimate reservoir volume. Electrical logs, radioactivity logs, core analyses, and other available data were used to prepare these maps as well as to estimate representative values for porosity and water saturation. When adequate data were available and when circumstances justified, material-balance methods were used to estimate OOIP and OGIP. Estimates of ultimate recovery were obtained after applying recovery factors to OOIP and OGIP. These recovery factors were based on consideration of the type of energy inherent in the reservoirs, analyses of the petroleum, the structural positions of the properties, and the production histories. When applicable, material balance and other engineering methods were used to estimate recovery factors based on an DeGolyer and MacNaughton 7 analysis of reservoir performance, including production rate, reservoir pressure, and reservoir fluid properties. 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 certain cases, reserves were estimated by incorporating elements of analogy with similar wells or reservoirs for which more complete data were available. In the evaluation of undeveloped reserves, type-well analysis was performed using well data from analogous reservoirs for which more complete historical performance data were available. For cases where history-matched dynamic models were available and applicable, model results were used to estimate recovery factors and reserves production forecasts. Data provided by DEE from wells drilled through December 31, 2025, 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 through December 2025. Cumulative production, as of December 31, 2025, was deducted from the estimated gross ultimate recovery to estimate gross reserves. Oil and condensate reserves estimated herein are to be recovered by normal field separation. Plant liquids reserves estimated herein include propane, butane, and pentanes and heavier fractions (C5+) and are the result of low-temperature plant processing. Oil, condensate, and plant liquids reserves included in this report are expressed in millions of barrels (106bbl). In these estimates, 1 barrel equals 42 United States gallons. Gas quantities estimated herein are expressed as natural gas, sales gas, and dry gas. Natural gas is the total gas produced from the reservoir prior to processing or separation and includes all nonhydrocarbon components. Sales gas is defined as the total gas to be produced from the reservoirs, measured at the inlet to the processing plant, after reduction for injection, fuel usage, flare, and shrinkage resulting from field separation. Dry gas is defined as the total gas to be produced from the reservoirs, measured at the tailgate of the processing plant, after reduction

DeGolyer and MacNaughton 8 for injection, fuel usage, flare, and shrinkage resulting from field separation and plant processing. Gas reserves estimated herein are reported as sales gas and dry gas. Gas quantities are expressed at a temperature base of 20 degrees Celsius (◦C) and at a pressure base of 1 atmosphere (atm). Gas quantities included in this report are expressed in billions of cubic feet (109ft3). 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. Condensate, sales gas, plant liquids, and dry gas reserves were estimated by applying yields and shrinkages, provided by DEE and modified according to historical data when applicable, to estimates of natural gas quantities. At the request of DEE, dry gas quantities estimated herein were converted to dry gas equivalent to liquids on a field-by-field basis using an energy equivalent factor based on the dry gas composition of each field, as provided by DEE. In addition, natural gas quantities estimated herein were converted to oil equivalent on a field-by-field basis using an energy equivalent factor reflecting the yields and shrinkages of each field, as provided by DEE and modified according to historical data when applicable. In certain cases, the energy equivalent factors, yields, and shrinkages provided by DEE were modified considering the recent historical data. Gas quantities and reserves were estimated by considering the historical use of gas from each field and the natural gas usage plan provided by DEE. DEE has represented that the development activities provided and evaluated herein were approved internally within DEE. In general, development activities provided by DEE are scheduled to initiate within 5 years of the as-of date of this report for activities associated with proved undeveloped reserves. However, certain development activities associated with proved undeveloped reserves are scheduled to be initiated more than 5 years after initial disclosure. DeGolyer and MacNaughton 9 Primary Economic Assumptions This report has been prepared using initial prices, expenses, and costs provided by DEE 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 and Condensate Prices DEE has represented that the oil and condensate 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. As represented by DEE, the reference price utilized is the Mexican Mix reference price, which is composed of the Istmo, Maya, and Olmeca reference prices and is calculated based on a formula that includes the West Texas Sour, Light Louisiana Sweet, Brent, Oman, and Dubai reference prices. DEE supplied differentials by field to an average Mexican Mix reference price of U.S.$64.10 per barrel and the prices were held constant thereafter. The volume-weighted average adjusted prices attributable to the estimated proved reserves over the lives of the properties were U.S.$71.62 per barrel of oil and U.S.$26.75 per barrel of condensate. These prices were not escalated for inflation. Gas Prices DEE has represented that the gas 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. Each field's calorific value, which includes plant liquids, was used to determine each field's gas price. The volume-weighted average adjusted price attributable to the estimated proved reserves over the lives of the properties was U.S.$4.58 per thousand cubic feet of gas. These prices were not escalated for inflation. DeGolyer and MacNaughton 10 Operating Expenses, Capital Costs, and Abandonment Costs Estimates of operating expenses and future capital expenditures, provided by DEE 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 DEE and were not adjusted for inflation. Estimates of 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, 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 302(b), 1201, 1202(a) (1), (2), (3), (4), (8), and 1203(a) of Regulation S–K of the SEC; provided, however, that (i) estimates of proved developed and proved undeveloped reserves are not presented at the beginning of the year and (ii) certain development activities associated with proved undeveloped reserves are scheduled to be initiated more than 5 years after initial disclosure. 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. DeGolyer and MacNaughton 11 Summary of Conclusions DeGolyer and MacNaughton has performed an independent evaluation of the extent of the estimated net proved oil, condensate, and gas reserves of certain properties in which DEE has represented it holds an interest. DEE has represented that its estimated net proved reserves attributable to the evaluated properties were based on the definition of proved reserves of the SEC. DEE's estimates of the net proved quantities and reserves, as of January 1, 2026, attributable to these properties, which represent 4.87 percent of DEE's reserves on a net oil equivalent basis, are summarized as follows, expressed in millions of barrels (106bbl), billions of cubic feet (109ft3), and millions of barrels of oil equivalent (106boe): Estimated by DEE as of January 1, 2026 Net Proved Reserves Natural Dry Gas Gas Sales Plant Dry Equivalent Oil Properties Evaluated by Quantities Oil Condensate Gas Liquids Gas To Liquids Equivalent DeGolyer and MacNaughton (109ft3) (106bbl) (106bbl) (109ft3) (106bbl) (109ft3) (106boe) (106boe) Proved Developed 939.8 147.0 2.3 916.7 61.2 642.1 123.5 334.0 Proved Undeveloped 48.9 20.2 0.1 45.5 3.0 32.3 6.2 29.5 Total Proved 988.7 167.2 2.4 962.2 64.2 674.4 129.7 363.5 Notes: 1. Reserves were estimated to the economic limit and did not consider the expiration of the contracts. 2. Dry gas equivalent to liquids was calculated based on dry gas reserves. 3. Dry gas reserves estimated herein were converted to dry gas equivalent to liquids on a field-by-field basis using an energy equivalent factor reflecting the dry gas composition of each field. 4. Oil equivalent was calculated based on oil reserves and natural gas quantities. 5. Natural gas quantities estimated herein were converted to oil equivalent on a field-by-field basis using an energy equivalent factor reflecting the yields and shrinkages of each field. 6. DEE has represented that totals may vary due to rounding. In comparing the detailed net proved reserves estimates prepared by DeGolyer and MacNaughton and by DEE, differences have been found, both positive and negative, resulting in an aggregate difference of 9.31 percent when compared on the basis of net oil equivalent barrels. It is DeGolyer and MacNaughton's opinion that the net proved reserves estimates prepared by DEE on the properties evaluated and referred to above, when compared on the basis of net equivalent barrels, in aggregate, are reasonable. 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 January 1, 2026, estimated reserves.

("Ryder Scott") has conducted a reserves audit of the estimates of the proved reserves owned by the United Mexican States as of December 31, 2025. The estimates we audited were prepared by DEE's engineering and geological staff based on the definitions and disclosure guidelines of the United States Securities and Exchange Commission contained in Title 17, Code of Federal Regulations, Modernization of Oil and Gas Reporting, Final Rule released January 14, 2009, in the Federal Register (SEC regulations). Our third party reserves audit, completed on March 31, 2026, and presented herein, was prepared for public disclosure by Pemex in filings made with the SEC in accordance with the disclosure requirements set forth in the SEC regulations. The properties reviewed by Ryder Scott are certain properties located onshore in the DEE assets known as Abkatún-Pol-Chuc and Litoral de Tabasco, in the Marine Southwest region, within the Territorial Waters of the Gulf of Mexico. The properties reviewed by Ryder Scott account for a portion of DEE's total net proved reserves as of December 31, 2025. Based on the estimates of total net proved reserves prepared by DEE, the reserves audit conducted by Ryder Scott addresses 11.3 percent of the total proved developed net liquid hydrocarbon reserves and 9.2 percent of the total proved developed net gas reserves or 10.1 percent of the total proved developed net reserves on a barrel of oil equivalent, BOE basis, and 4.9 percent of the total proved undeveloped net liquid hydrocarbon reserves and 2.9 percent of the total proved undeveloped net gas reserves or 3.8 percent of the total proved undeveloped net reserves on a barrel of oil equivalent, BOE basis, of DEE. On a total net reserves basis, the proved reserves audited by Ryder Scott represent 7.6 percent of Pemex´s total proved net reserves in the country on a barrel of oil equivalent, BOE basis. As prescribed by the Society of Petroleum Engineers in Paragraph 2.2(f) of the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (SPE auditing standards), a reserves audit is defined as "the process of reviewing certain of the pertinent facts interpreted and assumptions made that have resulted in an estimate of reserves and/or Reserves Information prepared by others and the rendering of an opinion about (1) the appropriateness of the methodologies employed; (2) the adequacy and quality of the data relied upon; (3) the depth and thoroughness of the reserves Dirección de Exploración y Extracción – Abkatún-Pol-Chuc and Litoral de Tabasco Assets April 17, 2026 Page 2 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS estimation process; (4) the classification of reserves appropriate to the relevant definitions used; and (5) the reasonableness of the estimated reserve quantities and/or Reserves Information." Reserves Information may consist of various estimates pertaining to the extent and value of petroleum properties. Based on our review, including the data, technical processes and interpretations presented by DEE, it is our opinion that the overall procedures and methodologies utilized by DEE in preparing their estimates of the proved reserves as of December 31, 2025 comply with the current SEC regulations, and that the overall proved reserves for the reviewed properties as estimated by DEE are, in the aggregate, reasonable within the established audit tolerance guidelines of 10 percent set forth in the SPE auditing standards. The estimated reserves presented in this report are related to hydrocarbon prices. DEE has informed us that in the preparation of their reserves and income projections, as of December 31, 2025, they used average prices during the 12-month period prior to the "as of date" of this report, determined as the unweighted arithmetic averages of the prices in effect on the first-day-of-the-month for each month within such period, unless prices were defined by contractual arrangements, as required by the SEC regulations. Actual future prices may vary considerably from the prices required by SEC regulations. The reserves volumes and the income attributable thereto have a direct relationship to the hydrocarbon prices actually received; therefore, volumes of reserves actually recovered may differ significantly from the estimated quantities presented in this report.

The net remaining reserves are also shown herein on an equivalent unit (BOE) basis wherein natural gas is converted to oil equivalent barrels using a specific factor for each field. MMBOE represents million barrels of oil equivalent. Reserves Included in This Report In our opinion, the proved reserves reviewed by us and presented in this report conform to the definition as set forth in the Securities and Exchange Commission's Regulations Part 210.4-10(a). An abridged version of the SEC reserves definitions from 210.4-10(a) entitled "Petroleum Reserves Definitions" is included as an attachment to this report. The various proved reserves status categories are defined in the attachment to this report entitled "PETROLEUM RESERVES STATUS DEFINITIONS AND GUIDELINES" in this report. The proved developed non-producing reserves included herein consist of the Shut-In and Behind Pipe status categories. Reserves are "estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations." All reserves estimates involve an assessment of the uncertainty relating the likelihood that the actual remaining quantities recovered will be greater or less than the estimated quantities determined as of the date the estimate is made. The uncertainty depends primarily on the amount of reliable geologic and engineering data available at the time of the estimate and the interpretation of these data. The relative degree of uncertainty may be conveyed by placing reserves into one of two principal categories, either proved or unproved. Unproved reserves are less certain to be recovered than proved reserves and may be further sub-categorized as probable and possible reserves to denote progressively increasing uncertainty in their recoverability. At DEE's request, this report addresses only the proved reserves attributable to the properties reviewed herein. 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." The proved reserves included herein were estimated using deterministic methods. The SEC has defined reasonable certainty for proved reserves, when based on deterministic methods, as a "high degree of confidence that the quantities will be recovered." Proved reserves estimates will generally be revised only as additional geologic or engineering data become available or as economic conditions change. For proved reserves, the SEC states that "as changes due to increased availability of geoscience (geological, geophysical, and geochemical), engineering, and economic data are made to the estimated ultimate recovery (EUR) with time, reasonably certain EUR is much more likely to increase or remain constant than to decrease." Moreover, estimates of proved reserves may be revised as a result of future operations, effects of regulation by governmental agencies or geopolitical or economic risks. Therefore, the proved reserves included in this report are estimates only and should not be construed as being exact quantities. They may or may not be actually recovered. Audit Data, Methodology, Procedure and Assumptions The estimation of reserves involves two distinct determinations. The first determination results in the estimation of the quantities of recoverable oil and gas and the second determination results in the

Dirección de Exploración y Extracción – Abkatún-Pol-Chuc and Litoral de Tabasco Assets April 17, 2026 Page 4 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS estimation of the uncertainty associated with those estimated quantities in accordance with the definitions set forth by the Securities and Exchange Commission's Regulations Part 210.4-10(a). The process of estimating the quantities of recoverable oil and gas reserves relies on the use of certain generally accepted analytical procedures. These analytical procedures fall into three broad categories or methods: (1) performance-based methods; (2) volumetric-based methods; and (3) analogy. These methods may be used individually or in combination by the reserves evaluator in the process of estimating the quantities of reserves. Reserves evaluators must select the method or combination of methods that in their professional judgment is most appropriate given the nature and amount of reliable geoscience and engineering data available at the time of the estimate, the established or anticipated performance characteristics of the reservoir being evaluated and the stage of development or producing maturity of the property. In many cases, the analysis of the available geoscience and engineering data and the subsequent interpretation of this data may indicate a range of possible outcomes in an estimate, irrespective of the method selected by the evaluator. When a range in the quantity of reserves is identified, the evaluator must determine the uncertainty associated with the incremental quantities of the reserves. If the reserves quantities are estimated using the deterministic incremental approach, the uncertainty for each discrete incremental quantity of the reserves is addressed by the reserves category assigned by the evaluator. Therefore, it is the categorization of reserves quantities as proved, probable and/or possible that addresses the inherent uncertainty in the estimated quantities reported. For proved reserves, uncertainty is defined by the SEC as reasonable certainty wherein the "quantities actually recovered are much more likely to be achieved than not." The SEC states that "probable reserves are those additional reserves that are less certain to be recovered than proved reserves but which, together with proved reserves, are as likely as not to be recovered." The SEC states that "possible reserves are those additional reserves that are less certain to be recovered than probable reserves and the total quantities ultimately recovered from a project have a low probability of exceeding proved plus probable plus possible reserves." All quantities of reserves within the same reserves category must meet the SEC definitions as noted above. Estimates of reserves quantities and their associated reserves categories may be revised in the future as additional geoscience or engineering data become available. Furthermore, estimates of reserves quantities and their associated reserves categories may also be revised due to other factors such as changes in economic conditions, results of future operations, effects of regulation by governmental agencies or geopolitical or economic risks as previously noted herein. The proved reserves prepared by DEE for the properties that we reviewed were estimated by performance methods, the volumetric method, analogy, or a combination of methods. The performance methods include, but may not be limited to, decline curve analysis and material balance, which utilized extrapolations of historical production and pressure data available through December 2025, in those cases where such data were considered to be definitive. The data utilized in these analyses were furnished to Ryder Scott by DEE and were considered sufficient for the purpose thereof. The volumetric method, analogy, or a combination of these methods were used to estimate the proved producing reserves for certain fields and reservoirs. These methods were used where there were inadequate historical performance data to establish a definitive trend and where the use of production performance data as a basis for the reserve estimates was considered to be inappropriate. All of the proved non-producing and undeveloped reserves that we reviewed were estimated by the volumetric method, analogy, or a combination of methods. The volumetric analysis utilized pertinent well and seismic data furnished to Ryder Scott by DEE for our review that were available through December 2025. The data utilized from the analogues in conjunction with well and seismic data incorporated into the volumetric analysis were considered sufficient for the purpose thereof. Dirección de Exploración y Extracción – Abkatún-Pol-Chuc and Litoral de Tabasco Assets April 17, 2026 Page 5 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS To estimate economically producible proved oil and gas reserves many factors and assumptions are considered including, but not limited to, the use of reservoir parameters derived from geological, geophysical and engineering data that cannot be measured directly, economic criteria based on current costs and SEC pricing requirements, and forecasts of future production rates. Under the SEC regulations 210.4-10(a)(22)(v) and (26), proved reserves must be anticipated to be economically producible from a given date forward based on existing economic conditions including the prices and costs at which economic producibility from a reservoir is to be determined. While it may reasonably be anticipated that the future prices received for the sale of production and the operating costs and other costs relating to such production may increase or decrease from those under existing economic conditions, such changes were, in accordance with rules adopted by the SEC, omitted from consideration in conducting this review. As stated previously, proved reserves must be anticipated to be economically producible from a given date forward based on existing economic conditions including the prices and costs at which economic producibility from a reservoir is to be determined. To confirm that the proved reserves reviewed by us meet the SEC requirements to be economically producible, we have reviewed certain primary economic data utilized by DEE relating to hydrocarbon prices and costs as noted herein. The hydrocarbon prices furnished by DEE for the properties reviewed by us are based on SEC price parameters using the average prices during the 12-month period prior to the "as of date" of this report, determined as the unweighted arithmetic averages of the prices in effect on the first-day-of-the- month for each month within such period, unless prices were defined by contractual arrangements. For hydrocarbon products sold under contract, the contract prices, including fixed and determinable escalations exclusive of inflation adjustments, were used until expiration of the contract. Upon contract expiration, the prices were adjusted to the 12-month unweighted arithmetic average as previously described. The initial SEC hydrocarbon prices in effect on December 31, 2025 for the properties reviewed by us were determined using the 12-month average first-day-of-the-month prices appropriate to the geographic areas where the hydrocarbons are sold. These prices are the actual prices received by DEE for the sale of hydrocarbon products. The table below summarizes DEE's net volume weighted prices adjusted for differentials for the properties reviewed by us by geographic areas and referred to herein as DEE's "average realized prices." The average realized prices shown in the table below were determined from DEE's estimate of the total future gross revenue before production taxes for the properties reviewed by us and DEE's estimate of the total net reserves for the properties reviewed by us. The data shown in the table below is presented in accordance with SEC disclosure requirements for each of the geographic areas shown and reviewed by us. Geographic Area (Activo) Product Price Reference Average Benchmark Prices Average Proved Realized Prices North America Mexico (Abkatún-Pol-Chuc and Litoral de Tabasco) Oil/Condensate WTI, Cushing $65.34/bbl $63.30/bbl Gas Henry Hub $3.39/MMBTU $4.75/Mcf Dirección de Exploración y Extracción – Abkatún-Pol-Chuc and Litoral de Tabasco Assets April 17, 2026 Page 6 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS The effects of derivative instruments designated as price hedges of oil and gas quantities are not reflected in DEE's individual property evaluations. Accumulated gas production imbalances, if any, were not taken into account in the proved gas reserves estimates reviewed. The proved gas volumes included herein do not include volumes of gas consumed in operations as reserves. Operating costs furnished by DEE are based on the operating expense reports of DEE and include only those costs directly applicable to the fields or wells for the properties reviewed by us. The operating costs include a portion of general and administrative costs allocated directly to the fields and wells. The operating costs furnished by DEE were accepted as factual data and reviewed by us for their reasonableness; however, we have not conducted an independent verification of the data used by DEE. No deduction was made for loan repayments, interest expenses, or exploration and development prepayments that were not charged directly to the fields, wells or contract areas. Development costs furnished by DEE are based on authorizations for expenditure for the proposed work or actual costs for similar projects. The development costs furnished by DEE were accepted as factual data and reviewed by us for their reasonableness; however, we have not conducted an independent verification of the data used by DEE. The estimated net cost of abandonment after salvage was included by Pemex for properties where abandonment costs net of salvage were material. Pemex's estimates of the net abandonment costs were accepted without independent verification. The proved undeveloped reserves for the properties reviewed by us have been incorporated herein in accordance with DEE's plans to develop these reserves as of December 31, 2025. The implementation of these development plans as presented to us is subject to the approval process adopted by DEE's management. As the result of our inquiries during the course of our review, DEE has informed us that the development activities for the properties reviewed by us have been subjected to and received the internal approvals required by DEE's management at the appropriate local, regional and/or corporate level. Additionally, DEE has informed us that they are not aware of any legal, regulatory or political obstacles that would significantly alter their plans. While these plans could change from those under existing economic conditions as of December 31, 2025, such changes were, in accordance with rules adopted by the SEC, omitted from consideration in making this evaluation. Current costs used by DEE were held constant throughout the life of the properties. DEE's forecasts of future production rates are based on historical performance from wells currently on production. If no production decline trend has been established, future production rates were held constant until a decline in ability to produce was anticipated. An estimated rate of decline was then applied until depletion of the reserves. If a decline trend has been established, this trend was used as the basis for estimating future production rates. Test data and other related information were used by DEE to estimate the anticipated initial production rates for those wells or locations that are not currently producing. For reserves not yet on production, sales were estimated to commence at an anticipated date furnished by DEE. Wells or locations that are not currently producing may start producing earlier or later than anticipated in DEE's estimates due to unforeseen factors causing a change in the timing to initiate production. Such factors may include delays due to weather, the availability of rigs, the sequence of drilling, completing and/or recompleting wells and/or constraints set by regulatory bodies. The future production rates from wells currently on production or wells or locations that are not currently producing may be more or less than estimated because of changes including, but not limited Dirección de Exploración y Extracción – Abkatún-Pol-Chuc and Litoral de Tabasco Assets April 17, 2026 Page 7 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS to, reservoir performance, operating conditions related to surface facilities, compression and artificial lift, pipeline capacity and/or operating conditions, producing market demand and/or allowables or other constraints set by regulatory bodies. Ryder Scott did not evaluate the country and geopolitical risks in the country of Mexico where all of the subject properties are located. DEE's operations may be subject to various levels of governmental controls and regulations. These controls and regulations may include, but may not be limited to, matters relating to land tenure and use, drilling and production practices, environmental protection, marketing and pricing policies, various taxes and levies are subject to change from time to time. Such changes in governmental regulations and policies may cause volumes of proved reserves actually recovered and amounts of proved income actually received to differ significantly from the estimated quantities. The estimates of proved reserves presented herein were based upon a review of the subject properties; however, we have not made any field examination of the properties. No consideration was given in this report to potential environmental liabilities that may exist nor were any costs included by DEE for potential liabilities to restore and clean up damages, if any, caused by past operating practices. Certain technical personnel of DEE are responsible for the preparation of reserves estimates on new properties and for the preparation of revised estimates, when necessary, on old properties. These personnel assembled the necessary data and maintained the data and workpapers in an orderly manner. We consulted with these technical personnel and had access to their workpapers and supporting data in the course of our audit. DEE has informed us that they have furnished us all of the material accounts, records, geological and engineering data, and reports and other data required for this investigation. In performing our audit of DEE's forecast of future proved production, we have relied upon data furnished by DEE with respect to property interests, production and well tests from examined wells, normal direct costs of operating the properties, other costs such as transportation and/or processing fees, recompletion and development costs, development plans, abandonment costs after salvage, product prices based on the SEC regulations, adjustments or differentials to product prices, geological structural and isochore maps, well logs, core analyses, and pressure measurements. Ryder Scott reviewed such factual data for its reasonableness; however, we have not conducted an independent verification of the data furnished by DEE. The data described herein were accepted as authentic and sufficient for determining the reserves unless, during the course of our examination, a matter of question came to our attention in which case the data were not accepted until all questions were satisfactorily resolved. We consider the factual data furnished to us by DEE to be appropriate and sufficient for the purpose of our review of DEE's estimates of reserves. In summary, we consider the assumptions, data, methods and analytical procedures used by DEE and as reviewed by us appropriate for the purpose hereof, and we have used all such methods and procedures that we consider necessary and appropriate under the circumstances to render the conclusions set forth herein. Audit Opinion Based on our review, including the data, technical processes and interpretations presented by DEE, it is our opinion that the overall procedures and methodologies utilized by DEE in preparing their estimates of the proved reserves as of December 31, 2025 comply with the current SEC regulations and that the overall proved reserves in terms of barrels of oil equivalent (BOE) for the reviewed properties as estimated by DEE are, in the aggregate, reasonable within the established audit tolerance guidelines of 10 percent as set forth in the SPE auditing standards.

Mr. Ramirez has also presented courses on the SEC and SPE-PRMS reserves definitions on various occasions during 2011, 2012, 2013, 2015, 2017, 2018 2020, 2021 and 2025. Based on his educational background, professional training and more than 40 years of practical experience in the estimation and evaluation of petroleum reserves, Mr. Ramirez has attained the professional qualifications as a Reserves Evaluator and Reserves Auditor set forth in Article III of the "Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information" promulgated by the Society of Petroleum Engineers as of June 2019. RYDER SCOTT COMPANY PETROLEUM CONSULTANTS PETROLEUM RESERVES DEFINITIONS As Adapted From: RULE 4-10(a) of REGULATION S-X PART 210 UNITED STATES SECURITIES AND EXCHANGE COMMISSION (SEC) PREAMBLE On January 14, 2009, the United States Securities and Exchange Commission (SEC) published the "Modernization of Oil and Gas Reporting; Final Rule" in the Federal Register of National Archives and Records Administration (NARA). The "Modernization of Oil and Gas Reporting; Final Rule" includes revisions and additions to the definition section in Rule 4-10 of Regulation S-X, revisions and additions to the oil and gas reporting requirements in Regulation S-K, and amends and codifies Industry Guide 2 in Regulation S-K. The "Modernization of Oil and Gas Reporting; Final Rule", including all references to Regulation S-X and Regulation S-K, shall be referred to herein collectively as the "SEC regulations". The SEC regulations take effect for all filings made with the United States Securities and Exchange Commission as of December 31, 2009, or after January 1, 2010. Reference should be made to the full text under Title 17, Code of Federal Regulations, Regulation S-X Part 210, Rule 4-10(a) for the complete definitions (direct passages excerpted in part or wholly from the aforementioned SEC document are denoted in italics herein). Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. All reserve estimates involve an assessment of the uncertainty relating the likelihood that the actual remaining quantities recovered will be greater or less than the estimated quantities determined as of the date the estimate is made. The uncertainty depends chiefly on the amount of reliable geologic and engineering data available at the time of the estimate and the interpretation of these data. The relative degree of uncertainty may be conveyed by placing reserves into one of two principal classifications, either proved or unproved. Unproved reserves are less certain to be recovered than proved reserves and may be further sub-classified as probable and possible reserves to denote progressively increasing uncertainty in their recoverability. Under the SEC regulations as of December 31, 2009, or after January 1, 2010, a company may optionally disclose estimated quantities of probable or possible oil and gas reserves in documents publicly filed with the SEC. The SEC regulations continue to prohibit disclosure of estimates of oil and gas resources other than reserves and any estimated values of such resources in any document publicly filed with the SEC unless such information is required to be disclosed in the document by foreign or state law as noted in §229.1202 Instruction to Item 1202. Reserves estimates will generally be revised only as additional geologic or engineering data become available or as economic conditions change. Reserves may be attributed to either natural energy or improved recovery methods. Improved recovery methods include all methods for supplementing natural energy or altering natural forces in the reservoir to increase ultimate recovery. Examples of such methods are pressure maintenance, natural gas cycling, waterflooding, thermal methods, chemical flooding, and the use of miscible and immiscible displacement fluids. Other improved recovery methods may be developed in the future as petroleum technology continues to evolve. Reserves may be attributed to either conventional or unconventional petroleum accumulations. Petroleum accumulations are considered as either conventional or unconventional based on the nature of their in-place characteristics, extraction method applied, or degree of processing prior to sale.

![](exhibit156reportsonreser004.jpg)

PETROLEUM RESERVES DEFINITIONS Page 2 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS Examples of unconventional petroleum accumulations include coalbed or coalseam methane (CBM/CSM), basin-centered gas, shale gas, gas hydrates, natural bitumen and oil shale deposits. These unconventional accumulations may require specialized extraction technology and/or significant processing prior to sale. Reserves do not include quantities of petroleum being held in inventory. Because of the differences in uncertainty, caution should be exercised when aggregating quantities of petroleum from different reserves categories. RESERVES (SEC DEFINITIONS) Securities and Exchange Commission Regulation S-X §210.4-10(a)(26) defines reserves as follows: Reserves. Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering oil and gas or related substances to market, and all permits and financing required to implement the project. Note to paragraph (a)(26): Reserves should not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that are clearly separated from a known accumulation by a non-productive reservoir (i.e., absence of reservoir, structurally low reservoir, or negative test results). Such areas may contain prospective resources (i.e., potentially recoverable resources from undiscovered accumulations). PROVED RESERVES (SEC DEFINITIONS) Securities and Exchange Commission Regulation S-X §210.4-10(a)(22) defines proved oil and gas reserves 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 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. PETROLEUM RESERVES DEFINITIONS Page 3 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS PROVED RESERVES (SEC DEFINITIONS) CONTINUED (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 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. RYDER SCOTT COMPANY PETROLEUM CONSULTANTS PETROLEUM RESERVES STATUS DEFINITIONS AND GUIDELINES As Adapted From: RULE 4-10(a) of REGULATION S-X PART 210 UNITED STATES SECURITIES AND EXCHANGE COMMISSION (SEC) and 2018 PETROLEUM RESOURCES MANAGEMENT SYSTEM (SPE-PRMS) Sponsored and Approved by: SOCIETY OF PETROLEUM ENGINEERS (SPE) WORLD PETROLEUM COUNCIL (WPC) AMERICAN ASSOCIATION OF PETROLEUM GEOLOGISTS (AAPG) SOCIETY OF PETROLEUM EVALUATION ENGINEERS (SPEE) SOCIETY OF EXPLORATION GEOPHYSICISTS (SEG) SOCIETY OF PETROPHYSICISTS AND WELL LOG ANALYSTS (SPWLA) EUROPEAN ASSOCIATION OF GEOSCIENTISTS & ENGINEERS (EAGE) Reserves status categories define the development and producing status of wells and reservoirs. Reference should be made to Title 17, Code of Federal Regulations, Regulation S-X Part 210, Rule 4- 10(a) and the SPE-PRMS as the following reserves status definitions are based on excerpts from the original documents (direct passages excerpted from the aforementioned SEC and SPE-PRMS documents are denoted in italics herein). DEVELOPED RESERVES (SEC DEFINITIONS) Securities and Exchange Commission Regulation S-X §210.4-10(a)(6) defines developed oil and gas reserves as follows: 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. Developed Producing (SPE-PRMS Definitions) While not a requirement for disclosure under the SEC regulations, developed oil and gas reserves may be further sub-classified according to the guidance contained in the SPE-PRMS as Producing or Non-Producing. Developed Producing Reserves Developed Producing Reserves are expected quantities to be recovered from completion intervals that are open and producing at the effective date of the estimate. PETROLEUM RESERVES STATUS DEFINITIONS AND GUIDELINES Page 2 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS Improved recovery reserves are considered producing only after the improved recovery project is in operation. Developed Non-Producing Developed Non-Producing Reserves include shut-in and behind-pipe Reserves. Shut-In Shut-in Reserves are expected to be recovered from: (1) completion intervals that are open at the time of the estimate but which have not yet started producing; (2) wells which were shut-in for market conditions or pipeline connections; or (3) wells not capable of production for mechanical reasons. Behind-Pipe Behind-pipe Reserves are expected to be recovered from zones in existing wells that will require additional completion work or future re-completion before start of production with minor cost to access these reserves. In all cases, production can be initiated or restored with relatively low expenditure compared to the cost of drilling a new well. UNDEVELOPED RESERVES (SEC DEFINITIONS) Securities and Exchange Commission Regulation S-X §210.4-10(a)(31) defines undeveloped oil and gas reserves as follows: 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 paragraph (a)(2) of this section, or by other evidence using reliable technology establishing reasonable certainty.

("Ryder Scott") has conducted a reserves audit of the estimates of the proved reserves owned by the United Mexican States as of December 31, 2025. The estimates we audited were prepared by DEE's engineering and geological staff based on the definitions and disclosure guidelines of the United States Securities and Exchange Commission contained in Title 17, Code of Federal Regulations, Modernization of Oil and Gas Reporting, Final Rule released January 14, 2009, in the Federal Register (SEC regulations). Our third party reserves audit, completed on March 31, 2026, and presented herein, was prepared for public disclosure by Pemex in filings made with the SEC in accordance with the disclosure requirements set forth in the SEC regulations. The properties reviewed by Ryder Scott are certain properties located onshore in the DEE assets known as Poza Rica-Altamira, in the North region, Mexico. The properties reviewed by Ryder Scott account for a portion of DEE's total net proved reserves as of December 31, 2025. Based on the estimates of total net proved reserves prepared by DEE, the reserves audit conducted by Ryder Scott addresses 1.7 percent of the total proved developed net liquid hydrocarbon reserves and 0.9 percent of the total proved developed net gas reserves or 1.3 percent of the total proved developed net reserves on a barrel of oil equivalent, BOE basis, and 2.1 percent of the total proved undeveloped net liquid hydrocarbon reserves and 11.7 percent of the total proved undeveloped net gas reserves or 5.1 percent of the total proved undeveloped net reserves on a barrel of oil equivalent, BOE basis, of DEE. On a total net reserves basis, the proved reserves audited by Ryder Scott represent 2.8 percent of Pemex´s total proved net reserves in the country on a barrel of oil equivalent, BOE basis. As prescribed by the Society of Petroleum Engineers in Paragraph 2.2(f) of the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (SPE auditing standards), a reserves audit is defined as "the process of reviewing certain of the pertinent facts interpreted and assumptions made that have resulted in an estimate of reserves and/or Reserves Information prepared by others and the rendering of an opinion about (1) the appropriateness of the methodologies employed; (2) the adequacy and quality of the data relied upon; (3) the depth and thoroughness of the reserves estimation process; (4) the classification of reserves appropriate to the relevant definitions used; and (5) Dirección de Exploración y Extracción – Poza Rica-Altamira Production Assets April 17, 2026 Page 2 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS the reasonableness of the estimated reserve quantities and/or Reserves Information." Reserves Information may consist of various estimates pertaining to the extent and value of petroleum properties. Based on our review, including the data, technical processes and interpretations presented by DEE, it is our opinion that the overall procedures and methodologies utilized by DEE in preparing their estimates of the proved reserves as of December 31, 2025 comply with the current SEC regulations, and that the overall proved reserves for the reviewed properties as estimated by DEE are, in the aggregate, reasonable within the established audit tolerance guidelines of 10 percent set forth in the SPE auditing standards. The estimated reserves presented in this report are related to hydrocarbon prices. DEE has informed us that in the preparation of their reserves and income projections, as of December 31, 2025, they used average prices during the 12-month period prior to the "as of date" of this report, determined as the unweighted arithmetic averages of the prices in effect on the first-day-of-the-month for each month within such period, unless prices were defined by contractual arrangements, as required by the SEC regulations. Actual future prices may vary considerably from the prices required by SEC regulations. The reserves volumes and the income attributable thereto have a direct relationship to the hydrocarbon prices actually received; therefore, volumes of reserves actually recovered may differ significantly from the estimated quantities presented in this report.

Reserves Included in This Report In our opinion, the proved reserves reviewed by us and presented in this report conform to the definition as set forth in the Securities and Exchange Commission's Regulations Part 210.4-10(a). An abridged version of the SEC reserves definitions from 210.4-10(a) entitled "Petroleum Reserves Definitions" is included as an attachment to this report. The various proved reserves status categories are defined in the attachment to this report entitled "PETROLEUM RESERVES STATUS DEFINITIONS AND GUIDELINES" in this report. The proved developed non-producing reserves included herein consist of the Shut-In and Behind Pipe status categories. Reserves are "estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations." All reserves estimates involve an assessment of the uncertainty relating the likelihood that the actual remaining quantities recovered will be greater or less than the estimated quantities determined as of the date the estimate is made. The uncertainty depends primarily on the amount of reliable geologic and engineering data available at the time of the estimate and the interpretation of these data. The relative degree of uncertainty may be conveyed by placing reserves into one of two principal categories, either proved or unproved. Unproved reserves are less certain to be recovered than proved reserves and may be further sub-categorized as probable and possible reserves to denote progressively increasing uncertainty in their recoverability. At DEE's request, this report addresses only the proved reserves attributable to the properties reviewed herein. 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." The proved reserves included herein were estimated using deterministic methods. The SEC has defined reasonable certainty for proved reserves, when based on deterministic methods, as a "high degree of confidence that the quantities will be recovered." Proved reserves estimates will generally be revised only as additional geologic or engineering data become available or as economic conditions change. For proved reserves, the SEC states that "as changes due to increased availability of geoscience (geological, geophysical, and geochemical), engineering, and economic data are made to the estimated ultimate recovery (EUR) with time, reasonably certain EUR is much more likely to increase or remain constant than to decrease." Moreover, estimates of proved reserves may be revised as a result of future operations, effects of regulation by governmental agencies or geopolitical or economic risks. Therefore, the proved reserves included in this report are estimates only and should not be construed as being exact quantities. They may or may not be actually recovered. Audit Data, Methodology, Procedure and Assumptions The estimation of reserves involves two distinct determinations. The first determination results in the estimation of the quantities of recoverable oil and gas and the second determination results in the

Dirección de Exploración y Extracción – Poza Rica-Altamira Production Assets April 17, 2026 Page 4 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS estimation of the uncertainty associated with those estimated quantities in accordance with the definitions set forth by the Securities and Exchange Commission's Regulations Part 210.4-10(a). The process of estimating the quantities of recoverable oil and gas reserves relies on the use of certain generally accepted analytical procedures. These analytical procedures fall into three broad categories or methods: (1) performance-based methods; (2) volumetric-based methods; and (3) analogy. These methods may be used individually or in combination by the reserves evaluator in the process of estimating the quantities of reserves. Reserves evaluators must select the method or combination of methods that in their professional judgment is most appropriate given the nature and amount of reliable geoscience and engineering data available at the time of the estimate, the established or anticipated performance characteristics of the reservoir being evaluated and the stage of development or producing maturity of the property. In many cases, the analysis of the available geoscience and engineering data and the subsequent interpretation of this data may indicate a range of possible outcomes in an estimate, irrespective of the method selected by the evaluator. When a range in the quantity of reserves is identified, the evaluator must determine the uncertainty associated with the incremental quantities of the reserves. If the reserves quantities are estimated using the deterministic incremental approach, the uncertainty for each discrete incremental quantity of the reserves is addressed by the reserves category assigned by the evaluator. Therefore, it is the categorization of reserves quantities as proved, probable and/or possible that addresses the inherent uncertainty in the estimated quantities reported. For proved reserves, uncertainty is defined by the SEC as reasonable certainty wherein the "quantities actually recovered are much more likely to be achieved than not." The SEC states that "probable reserves are those additional reserves that are less certain to be recovered than proved reserves but which, together with proved reserves, are as likely as not to be recovered." The SEC states that "possible reserves are those additional reserves that are less certain to be recovered than probable reserves and the total quantities ultimately recovered from a project have a low probability of exceeding proved plus probable plus possible reserves." All quantities of reserves within the same reserves category must meet the SEC definitions as noted above. Estimates of reserves quantities and their associated reserves categories may be revised in the future as additional geoscience or engineering data become available. Furthermore, estimates of reserves quantities and their associated reserves categories may also be revised due to other factors such as changes in economic conditions, results of future operations, effects of regulation by governmental agencies or geopolitical or economic risks as previously noted herein. The proved reserves prepared by DEE for the properties that we reviewed were estimated by performance methods, the volumetric method, analogy, or a combination of methods. The performance methods include, but may not be limited to, decline curve analysis and material balance, which utilized extrapolations of historical production and pressure data available through December 2025, in those cases where such data were considered to be definitive. The data utilized in these analyses were furnished to Ryder Scott by DEE and were considered sufficient for the purpose thereof. The volumetric method, analogy, or a combination of these methods were used to estimate the proved producing reserves for certain fields and reservoirs. These methods were used where there were inadequate historical performance data to establish a definitive trend and where the use of production performance data as a basis for the reserve estimates was considered to be inappropriate. All of the proved non-producing and undeveloped reserves that we reviewed were estimated by the volumetric method, analogy, or a combination of methods. The volumetric analysis utilized pertinent well and seismic data furnished to Ryder Scott by DEE for our review that were available through December 2025. The data utilized from the analogues in conjunction with well and seismic data incorporated into the volumetric analysis were considered sufficient for the purpose thereof. Dirección de Exploración y Extracción – Poza Rica-Altamira Production Assets April 17, 2026 Page 5 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS To estimate economically producible proved oil and gas reserves many factors and assumptions are considered including, but not limited to, the use of reservoir parameters derived from geological, geophysical and engineering data that cannot be measured directly, economic criteria based on current costs and SEC pricing requirements, and forecasts of future production rates. Under the SEC regulations 210.4-10(a)(22)(v) and (26), proved reserves must be anticipated to be economically producible from a given date forward based on existing economic conditions including the prices and costs at which economic producibility from a reservoir is to be determined. While it may reasonably be anticipated that the future prices received for the sale of production and the operating costs and other costs relating to such production may increase or decrease from those under existing economic conditions, such changes were, in accordance with rules adopted by the SEC, omitted from consideration in conducting this review. As stated previously, proved reserves must be anticipated to be economically producible from a given date forward based on existing economic conditions including the prices and costs at which economic producibility from a reservoir is to be determined. To confirm that the proved reserves reviewed by us meet the SEC requirements to be economically producible, we have reviewed certain primary economic data utilized by DEE relating to hydrocarbon prices and costs as noted herein. The hydrocarbon prices furnished by DEE for the properties reviewed by us are based on SEC price parameters using the average prices during the 12-month period prior to the "as of date" of this report, determined as the unweighted arithmetic averages of the prices in effect on the first-day-of-the- month for each month within such period, unless prices were defined by contractual arrangements. For hydrocarbon products sold under contract, the contract prices, including fixed and determinable escalations exclusive of inflation adjustments, were used until expiration of the contract. Upon contract expiration, the prices were adjusted to the 12-month unweighted arithmetic average as previously described. The initial SEC hydrocarbon prices in effect on December 31, 2025 for the properties reviewed by us were determined using the 12-month average first-day-of-the-month prices appropriate to the geographic areas where the hydrocarbons are sold. These prices are the actual prices received by DEE for the sale of hydrocarbon products. The table below summarizes DEE's net volume weighted prices adjusted for differentials for the properties reviewed by us by geographic areas and referred to herein as DEE's "average realized prices." The average realized prices shown in the table below were determined from DEE's estimate of the total future gross revenue before production taxes for the properties reviewed by us and DEE's estimate of the total net reserves for the properties reviewed by us. The data shown in the table below is presented in accordance with SEC disclosure requirements for each of the geographic areas shown and reviewed by us. Geographic Area (Activo) Product Price Reference Average Benchmark Prices Average Proved Realized Prices North America Mexico (Poza Rica- Altamira) Oil/Condensate WTI, Cushing $65.34/bbl $56.62/bbl Gas Henry Hub $3.39/MMBTU $3.42/Mcf Dirección de Exploración y Extracción – Poza Rica-Altamira Production Assets April 17, 2026 Page 6 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS The effects of derivative instruments designated as price hedges of oil and gas quantities are not reflected in DEE's individual property evaluations. Accumulated gas production imbalances, if any, were not taken into account in the proved gas reserves estimates reviewed. The proved gas volumes included herein do not include volumes of gas consumed in operations as reserves. Operating costs furnished by DEE are based on the operating expense reports of DEE and include only those costs directly applicable to the fields or wells for the properties reviewed by us. The operating costs include a portion of general and administrative costs allocated directly to the fields and wells. The operating costs furnished by DEE were accepted as factual data and reviewed by us for their reasonableness; however, we have not conducted an independent verification of the data used by DEE. No deduction was made for loan repayments, interest expenses, or exploration and development prepayments that were not charged directly to the fields, wells or contract areas. Development costs furnished by DEE are based on authorizations for expenditure for the proposed work or actual costs for similar projects. The development costs furnished by DEE were accepted as factual data and reviewed by us for their reasonableness; however, we have not conducted an independent verification of the data used by DEE. The estimated net cost of abandonment after salvage was included by Pemex for properties where abandonment costs net of salvage were material. Pemex's estimates of the net abandonment costs were accepted without independent verification. The proved undeveloped reserves for the properties reviewed by us have been incorporated herein in accordance with DEE's plans to develop these reserves as of December 31, 2025. The implementation of these development plans as presented to us is subject to the approval process adopted by DEE's management. As the result of our inquiries during the course of our review, DEE has informed us that the development activities for the properties reviewed by us have been subjected to and received the internal approvals required by DEE's management at the appropriate local, regional and/or corporate level. Additionally, DEE has informed us that they are not aware of any legal, regulatory or political obstacles that would significantly alter their plans. While these plans could change from those under existing economic conditions as of December 31, 2025, such changes were, in accordance with rules adopted by the SEC, omitted from consideration in making this evaluation. Current costs used by DEE were held constant throughout the life of the properties. DEE's forecasts of future production rates are based on historical performance from wells currently on production. If no production decline trend has been established, future production rates were held constant until a decline in ability to produce was anticipated. An estimated rate of decline was then applied until depletion of the reserves. If a decline trend has been established, this trend was used as the basis for estimating future production rates. Test data and other related information were used by DEE to estimate the anticipated initial production rates for those wells or locations that are not currently producing. For reserves not yet on production, sales were estimated to commence at an anticipated date furnished by DEE. Wells or locations that are not currently producing may start producing earlier or later than anticipated in DEE's estimates due to unforeseen factors causing a change in the timing to initiate production. Such factors may include delays due to weather, the availability of rigs, the sequence of drilling, completing and/or recompleting wells and/or constraints set by regulatory bodies. The future production rates from wells currently on production or wells or locations that are not currently producing may be more or less than estimated because of changes including, but not limited Dirección de Exploración y Extracción – Poza Rica-Altamira Production Assets April 17, 2026 Page 7 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS to, reservoir performance, operating conditions related to surface facilities, compression and artificial lift, pipeline capacity and/or operating conditions, producing market demand and/or allowables or other constraints set by regulatory bodies. Ryder Scott did not evaluate the country and geopolitical risks in the country of Mexico where all of the subject properties are located. DEE's operations may be subject to various levels of governmental controls and regulations. These controls and regulations may include, but may not be limited to, matters relating to land tenure and use, drilling and production practices, environmental protection, marketing and pricing policies, various taxes and levies are subject to change from time to time. Such changes in governmental regulations and policies may cause volumes of proved reserves actually recovered and amounts of proved income actually received to differ significantly from the estimated quantities. The estimates of proved reserves presented herein were based upon a review of the subject properties; however, we have not made any field examination of the properties. No consideration was given in this report to potential environmental liabilities that may exist nor were any costs included by DEE for potential liabilities to restore and clean up damages, if any, caused by past operating practices. Certain technical personnel of DEE are responsible for the preparation of reserves estimates on new properties and for the preparation of revised estimates, when necessary, on old properties. These personnel assembled the necessary data and maintained the data and workpapers in an orderly manner. We consulted with these technical personnel and had access to their workpapers and supporting data in the course of our audit. DEE has informed us that they have furnished us all of the material accounts, records, geological and engineering data, and reports and other data required for this investigation. In performing our audit of DEE's forecast of future proved production, we have relied upon data furnished by DEE with respect to property interests, production and well tests from examined wells, normal direct costs of operating the properties, other costs such as transportation and/or processing fees, recompletion and development costs, development plans, abandonment costs after salvage, product prices based on the SEC regulations, adjustments or differentials to product prices, geological structural and isochore maps, well logs, core analyses, and pressure measurements. Ryder Scott reviewed such factual data for its reasonableness; however, we have not conducted an independent verification of the data furnished by DEE. The data described herein were accepted as authentic and sufficient for determining the reserves unless, during the course of our examination, a matter of question came to our attention in which case the data were not accepted until all questions were satisfactorily resolved. We consider the factual data furnished to us by DEE to be appropriate and sufficient for the purpose of our review of DEE's estimates of reserves. In summary, we consider the assumptions, data, methods and analytical procedures used by DEE and as reviewed by us appropriate for the purpose hereof, and we have used all such methods and procedures that we consider necessary and appropriate under the circumstances to render the conclusions set forth herein. Audit Opinion Based on our review, including the data, technical processes and interpretations presented by DEE, it is our opinion that the overall procedures and methodologies utilized by DEE in preparing their estimates of the proved reserves as of December 31, 2025 comply with the current SEC regulations and that the overall proved reserves in terms of barrels of oil equivalent (BOE) for the reviewed properties as estimated by DEE are, in the aggregate, reasonable within the established audit tolerance guidelines of 10 percent as set forth in the SPE auditing standards. Ryder Scott found the processes and controls

We were in reasonable agreement with DEE's estimates of proved reserves for the subject properties that we reviewed; although in certain cases there was more than an acceptable variance between DEE's estimates and our estimates due to a difference in interpretation of data. However notwithstanding, it is our opinion that on an aggregate basis the data presented herein for the subject properties that we reviewed fairly reflects the estimated net reserves owned by the United Mexican States.

Mr. Ramirez has also presented courses on the SEC and SPE-PRMS reserves definitions on various occasions during 2011, 2012, 2013, 2015, 2017, 2018 2020, 2021 and 2025. Based on his educational background, professional training and more than 40 years of practical experience in the estimation and evaluation of petroleum reserves, Mr. Ramirez has attained the professional qualifications as a Reserves Evaluator and Reserves Auditor set forth in Article III of the "Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information" promulgated by the Society of Petroleum Engineers as of June 2019. RYDER SCOTT COMPANY PETROLEUM CONSULTANTS PETROLEUM RESERVES DEFINITIONS As Adapted From: RULE 4-10(a) of REGULATION S-X PART 210 UNITED STATES SECURITIES AND EXCHANGE COMMISSION (SEC) PREAMBLE On January 14, 2009, the United States Securities and Exchange Commission (SEC) published the "Modernization of Oil and Gas Reporting; Final Rule" in the Federal Register of National Archives and Records Administration (NARA). The "Modernization of Oil and Gas Reporting; Final Rule" includes revisions and additions to the definition section in Rule 4-10 of Regulation S-X, revisions and additions to the oil and gas reporting requirements in Regulation S-K, and amends and codifies Industry Guide 2 in Regulation S-K. The "Modernization of Oil and Gas Reporting; Final Rule", including all references to Regulation S-X and Regulation S-K, shall be referred to herein collectively as the "SEC regulations". The SEC regulations take effect for all filings made with the United States Securities and Exchange Commission as of December 31, 2009, or after January 1, 2010. Reference should be made to the full text under Title 17, Code of Federal Regulations, Regulation S-X Part 210, Rule 4-10(a) for the complete definitions (direct passages excerpted in part or wholly from the aforementioned SEC document are denoted in italics herein). Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. All reserve estimates involve an assessment of the uncertainty relating the likelihood that the actual remaining quantities recovered will be greater or less than the estimated quantities determined as of the date the estimate is made. The uncertainty depends chiefly on the amount of reliable geologic and engineering data available at the time of the estimate and the interpretation of these data. The relative degree of uncertainty may be conveyed by placing reserves into one of two principal classifications, either proved or unproved. Unproved reserves are less certain to be recovered than proved reserves and may be further sub-classified as probable and possible reserves to denote progressively increasing uncertainty in their recoverability. Under the SEC regulations as of December 31, 2009, or after January 1, 2010, a company may optionally disclose estimated quantities of probable or possible oil and gas reserves in documents publicly filed with the SEC. The SEC regulations continue to prohibit disclosure of estimates of oil and gas resources other than reserves and any estimated values of such resources in any document publicly filed with the SEC unless such information is required to be disclosed in the document by foreign or state law as noted in §229.1202 Instruction to Item 1202. Reserves estimates will generally be revised only as additional geologic or engineering data become available or as economic conditions change. Reserves may be attributed to either natural energy or improved recovery methods. Improved recovery methods include all methods for supplementing natural energy or altering natural forces in the reservoir to increase ultimate recovery. Examples of such methods are pressure maintenance, natural gas cycling, waterflooding, thermal methods, chemical flooding, and the use of miscible and immiscible displacement fluids. Other improved recovery methods may be developed in the future as petroleum technology continues to evolve. Reserves may be attributed to either conventional or unconventional petroleum accumulations. Petroleum accumulations are considered as either conventional or unconventional based on the nature of their in-place characteristics, extraction method applied, or degree of processing prior to sale.

![](exhibit156reportsonreser008.jpg)

PETROLEUM RESERVES DEFINITIONS Page 2 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS Examples of unconventional petroleum accumulations include coalbed or coalseam methane (CBM/CSM), basin-centered gas, shale gas, gas hydrates, natural bitumen and oil shale deposits. These unconventional accumulations may require specialized extraction technology and/or significant processing prior to sale. Reserves do not include quantities of petroleum being held in inventory. Because of the differences in uncertainty, caution should be exercised when aggregating quantities of petroleum from different reserves categories. RESERVES (SEC DEFINITIONS) Securities and Exchange Commission Regulation S-X §210.4-10(a)(26) defines reserves as follows: Reserves. Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering oil and gas or related substances to market, and all permits and financing required to implement the project. Note to paragraph (a)(26): Reserves should not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that are clearly separated from a known accumulation by a non-productive reservoir (i.e., absence of reservoir, structurally low reservoir, or negative test results). Such areas may contain prospective resources (i.e., potentially recoverable resources from undiscovered accumulations). PROVED RESERVES (SEC DEFINITIONS) Securities and Exchange Commission Regulation S-X §210.4-10(a)(22) defines proved oil and gas reserves 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 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. PETROLEUM RESERVES DEFINITIONS Page 3 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS PROVED RESERVES (SEC DEFINITIONS) CONTINUED (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 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. RYDER SCOTT COMPANY PETROLEUM CONSULTANTS PETROLEUM RESERVES STATUS DEFINITIONS AND GUIDELINES As Adapted From: RULE 4-10(a) of REGULATION S-X PART 210 UNITED STATES SECURITIES AND EXCHANGE COMMISSION (SEC) and 2018 PETROLEUM RESOURCES MANAGEMENT SYSTEM (SPE-PRMS) Sponsored and Approved by: SOCIETY OF PETROLEUM ENGINEERS (SPE) WORLD PETROLEUM COUNCIL (WPC) AMERICAN ASSOCIATION OF PETROLEUM GEOLOGISTS (AAPG) SOCIETY OF PETROLEUM EVALUATION ENGINEERS (SPEE) SOCIETY OF EXPLORATION GEOPHYSICISTS (SEG) SOCIETY OF PETROPHYSICISTS AND WELL LOG ANALYSTS (SPWLA) EUROPEAN ASSOCIATION OF GEOSCIENTISTS & ENGINEERS (EAGE) Reserves status categories define the development and producing status of wells and reservoirs. Reference should be made to Title 17, Code of Federal Regulations, Regulation S-X Part 210, Rule 4- 10(a) and the SPE-PRMS as the following reserves status definitions are based on excerpts from the original documents (direct passages excerpted from the aforementioned SEC and SPE-PRMS documents are denoted in italics herein). DEVELOPED RESERVES (SEC DEFINITIONS) Securities and Exchange Commission Regulation S-X §210.4-10(a)(6) defines developed oil and gas reserves as follows: 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. Developed Producing (SPE-PRMS Definitions) While not a requirement for disclosure under the SEC regulations, developed oil and gas reserves may be further sub-classified according to the guidance contained in the SPE-PRMS as Producing or Non-Producing. Developed Producing Reserves Developed Producing Reserves are expected quantities to be recovered from completion intervals that are open and producing at the effective date of the estimate. PETROLEUM RESERVES STATUS DEFINITIONS AND GUIDELINES Page 2 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS Improved recovery reserves are considered producing only after the improved recovery project is in operation. Developed Non-Producing Developed Non-Producing Reserves include shut-in and behind-pipe Reserves. Shut-In Shut-in Reserves are expected to be recovered from: (1) completion intervals that are open at the time of the estimate but which have not yet started producing; (2) wells which were shut-in for market conditions or pipeline connections; or (3) wells not capable of production for mechanical reasons. Behind-Pipe Behind-pipe Reserves are expected to be recovered from zones in existing wells that will require additional completion work or future re-completion before start of production with minor cost to access these reserves. In all cases, production can be initiated or restored with relatively low expenditure compared to the cost of drilling a new well. UNDEVELOPED RESERVES (SEC DEFINITIONS) Securities and Exchange Commission Regulation S-X §210.4-10(a)(31) defines undeveloped oil and gas reserves as follows: 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 paragraph (a)(2) of this section, or by other evidence using reliable technology establishing reasonable certainty.

("Ryder Scott") has conducted a reserves audit of the estimates of the proved reserves owned by the United Mexican States as of December 31, 2025. The estimates we audited were prepared by DEE's engineering and geological staff based on the definitions and disclosure guidelines of the United States Securities and Exchange Commission contained in Title 17, Code of Federal Regulations, Modernization of Oil and Gas Reporting, Final Rule released January 14, 2009, in the Federal Register (SEC regulations). Our third party reserves audit, completed on March 31, 2026, and presented herein, was prepared for public disclosure by Pemex in filings made with the SEC in accordance with the disclosure requirements set forth in the SEC regulations. The properties reviewed by Ryder Scott are certain properties located onshore in the DEE assets known as Samaria-Luna y Bellota-Jujo, in the Southwest region, Mexico. The properties reviewed by Ryder Scott account for a portion of DEE's total net proved reserves as of December 31, 2025. Based on the estimates of total net proved reserves prepared by DEE, the reserves audit conducted by Ryder Scott addresses 5.5 percent of the total proved developed net liquid hydrocarbon reserves and 3.5 percent of the total proved developed net gas reserves or 4.9 percent of the total proved developed net reserves on a barrel of oil equivalent, BOE basis, and 1.5 percent of the total proved undeveloped net liquid hydrocarbon reserves and 0.7 percent of the total proved undeveloped net gas reserves or 1.1 percent of the total proved undeveloped net reserves on a barrel of oil equivalent, BOE basis, of DEE. On a total net reserves basis, the proved reserves audited by Ryder Scott represent 3.4 percent of Pemex´s total proved net reserves in the country on a barrel of oil equivalent, BOE basis. As prescribed by the Society of Petroleum Engineers in Paragraph 2.2(f) of the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (SPE auditing standards), a reserves audit is defined as "the process of reviewing certain of the pertinent facts interpreted and assumptions made that have resulted in an estimate of reserves and/or Reserves Information prepared by others and the rendering of an opinion about (1) the appropriateness of the methodologies employed; (2) the adequacy and quality of the data relied upon; (3) the depth and thoroughness of the reserves estimation process; (4) the classification of reserves appropriate to the relevant definitions used; and (5) Dirección de Exploración y Extracción – Samaria-Luna y Bellota-Jujo Assets April 17, 2026 Page 2 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS the reasonableness of the estimated reserve quantities and/or Reserves Information." Reserves Information may consist of various estimates pertaining to the extent and value of petroleum properties. Based on our review, including the data, technical processes and interpretations presented by DEE, it is our opinion that the overall procedures and methodologies utilized by DEE in preparing their estimates of the proved reserves as of December 31, 2025 comply with the current SEC regulations, and that the overall proved reserves for the reviewed properties as estimated by DEE are, in the aggregate, reasonable within the established audit tolerance guidelines of 10 percent set forth in the SPE auditing standards. The estimated reserves presented in this report are related to hydrocarbon prices. DEE has informed us that in the preparation of their reserves and income projections, as of December 31, 2025, they used average prices during the 12-month period prior to the "as of date" of this report, determined as the unweighted arithmetic averages of the prices in effect on the first-day-of-the-month for each month within such period, unless prices were defined by contractual arrangements, as required by the SEC regulations. Actual future prices may vary considerably from the prices required by SEC regulations. The reserves volumes and the income attributable thereto have a direct relationship to the hydrocarbon prices actually received; therefore, volumes of reserves actually recovered may differ significantly from the estimated quantities presented in this report.

The net remaining reserves are also shown herein on an equivalent unit (BOE) basis wherein natural gas is converted to oil equivalent barrels using a specific factor for each field. MMBOE represents million barrels of oil equivalent. Reserves Included in This Report In our opinion, the proved reserves reviewed by us and presented in this report conform to the definition as set forth in the Securities and Exchange Commission's Regulations Part 210.4-10(a). An abridged version of the SEC reserves definitions from 210.4-10(a) entitled "Petroleum Reserves Definitions" is included as an attachment to this report. The various proved reserves status categories are defined in the attachment to this report entitled "PETROLEUM RESERVES STATUS DEFINITIONS AND GUIDELINES" in this report. The proved developed non-producing reserves included herein consist of the Shut-In and Behind Pipe status categories. Reserves are "estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations." All reserves estimates involve an assessment of the uncertainty relating the likelihood that the actual remaining quantities recovered will be greater or less than the estimated quantities determined as of the date the estimate is made. The uncertainty depends primarily on the amount of reliable geologic and engineering data available at the time of the estimate and the interpretation of these data. The relative degree of uncertainty may be conveyed by placing reserves into one of two principal categories, either proved or unproved. Unproved reserves are less certain to be recovered than proved reserves and may be further sub-categorized as probable and possible reserves to denote progressively increasing uncertainty in their recoverability. At DEE's request, this report addresses only the proved reserves attributable to the properties reviewed herein. 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." The proved reserves included herein were estimated using deterministic methods. The SEC has defined reasonable certainty for proved reserves, when based on deterministic methods, as a "high degree of confidence that the quantities will be recovered." Proved reserves estimates will generally be revised only as additional geologic or engineering data become available or as economic conditions change. For proved reserves, the SEC states that "as changes due to increased availability of geoscience (geological, geophysical, and geochemical), engineering, and economic data are made to the estimated ultimate recovery (EUR) with time, reasonably certain EUR is much more likely to increase or remain constant than to decrease." Moreover, estimates of proved reserves may be revised as a result of future operations, effects of regulation by governmental agencies or geopolitical or economic risks. Therefore, the proved reserves included in this report are estimates only and should not be construed as being exact quantities. They may or may not be actually recovered. Audit Data, Methodology, Procedure and Assumptions The estimation of reserves involves two distinct determinations. The first determination results in the estimation of the quantities of recoverable oil and gas and the second determination results in the estimation of the uncertainty associated with those estimated quantities in accordance with the definitions

Dirección de Exploración y Extracción – Samaria-Luna y Bellota-Jujo Assets April 17, 2026 Page 4 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS set forth by the Securities and Exchange Commission's Regulations Part 210.4-10(a). The process of estimating the quantities of recoverable oil and gas reserves relies on the use of certain generally accepted analytical procedures. These analytical procedures fall into three broad categories or methods: (1) performance-based methods; (2) volumetric-based methods; and (3) analogy. These methods may be used individually or in combination by the reserves evaluator in the process of estimating the quantities of reserves. Reserves evaluators must select the method or combination of methods that in their professional judgment is most appropriate given the nature and amount of reliable geoscience and engineering data available at the time of the estimate, the established or anticipated performance characteristics of the reservoir being evaluated and the stage of development or producing maturity of the property. In many cases, the analysis of the available geoscience and engineering data and the subsequent interpretation of this data may indicate a range of possible outcomes in an estimate, irrespective of the method selected by the evaluator. When a range in the quantity of reserves is identified, the evaluator must determine the uncertainty associated with the incremental quantities of the reserves. If the reserves quantities are estimated using the deterministic incremental approach, the uncertainty for each discrete incremental quantity of the reserves is addressed by the reserves category assigned by the evaluator. Therefore, it is the categorization of reserves quantities as proved, probable and/or possible that addresses the inherent uncertainty in the estimated quantities reported. For proved reserves, uncertainty is defined by the SEC as reasonable certainty wherein the "quantities actually recovered are much more likely to be achieved than not." The SEC states that "probable reserves are those additional reserves that are less certain to be recovered than proved reserves but which, together with proved reserves, are as likely as not to be recovered." The SEC states that "possible reserves are those additional reserves that are less certain to be recovered than probable reserves and the total quantities ultimately recovered from a project have a low probability of exceeding proved plus probable plus possible reserves." All quantities of reserves within the same reserves category must meet the SEC definitions as noted above. Estimates of reserves quantities and their associated reserves categories may be revised in the future as additional geoscience or engineering data become available. Furthermore, estimates of reserves quantities and their associated reserves categories may also be revised due to other factors such as changes in economic conditions, results of future operations, effects of regulation by governmental agencies or geopolitical or economic risks as previously noted herein. The proved reserves prepared by DEE for the properties that we reviewed were estimated by performance methods, the volumetric method, analogy, or a combination of methods. The performance methods include, but may not be limited to, decline curve analysis and material balance, which utilized extrapolations of historical production and pressure data available through December 2025, in those cases where such data were considered to be definitive. The data utilized in these analyses were furnished to Ryder Scott by DEE and were considered sufficient for the purpose thereof. The volumetric method, analogy, or a combination of these methods were used to estimate the proved producing reserves for certain fields and reservoirs. These methods were used where there were inadequate historical performance data to establish a definitive trend and where the use of production performance data as a basis for the reserve estimates was considered to be inappropriate. All of the proved non-producing and undeveloped reserves that we reviewed were estimated by the volumetric method, analogy, or a combination of methods. The volumetric analysis utilized pertinent well and seismic data furnished to Ryder Scott by DEE for our review that were available through December 2025. The data utilized from the analogues in conjunction with well and seismic data incorporated into the volumetric analysis were considered sufficient for the purpose thereof. Dirección de Exploración y Extracción – Samaria-Luna y Bellota-Jujo Assets April 17, 2026 Page 5 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS To estimate economically producible proved oil and gas reserves many factors and assumptions are considered including, but not limited to, the use of reservoir parameters derived from geological, geophysical and engineering data that cannot be measured directly, economic criteria based on current costs and SEC pricing requirements, and forecasts of future production rates. Under the SEC regulations 210.4-10(a)(22)(v) and (26), proved reserves must be anticipated to be economically producible from a given date forward based on existing economic conditions including the prices and costs at which economic producibility from a reservoir is to be determined. While it may reasonably be anticipated that the future prices received for the sale of production and the operating costs and other costs relating to such production may increase or decrease from those under existing economic conditions, such changes were, in accordance with rules adopted by the SEC, omitted from consideration in conducting this review. As stated previously, proved reserves must be anticipated to be economically producible from a given date forward based on existing economic conditions including the prices and costs at which economic producibility from a reservoir is to be determined. To confirm that the proved reserves reviewed by us meet the SEC requirements to be economically producible, we have reviewed certain primary economic data utilized by DEE relating to hydrocarbon prices and costs as noted herein. The hydrocarbon prices furnished by DEE for the properties reviewed by us are based on SEC price parameters using the average prices during the 12-month period prior to the "as of date" of this report, determined as the unweighted arithmetic averages of the prices in effect on the first-day-of-the- month for each month within such period, unless prices were defined by contractual arrangements. For hydrocarbon products sold under contract, the contract prices, including fixed and determinable escalations exclusive of inflation adjustments, were used until expiration of the contract. Upon contract expiration, the prices were adjusted to the 12-month unweighted arithmetic average as previously described. The initial SEC hydrocarbon prices in effect on December 31, 2025 for the properties reviewed by us were determined using the 12-month average first-day-of-the-month prices appropriate to the geographic areas where the hydrocarbons are sold. These prices are the actual prices received by DEE for the sale of hydrocarbon products. The table below summarizes DEE's net volume weighted prices adjusted for differentials for the properties reviewed by us by geographic areas and referred to herein as DEE's "average realized prices." The average realized prices shown in the table below were determined from DEE's estimate of the total future gross revenue before production taxes for the properties reviewed by us and DEE's estimate of the total net reserves for the properties reviewed by us. The data shown in the table below is presented in accordance with SEC disclosure requirements for each of the geographic areas shown and reviewed by us. Geographic Area (Activo) Product Price Reference Average Benchmark Prices Average Proved Realized Prices Southwest region, Mexico (Samaria- Luna y Bellota-Jujo) Oil/Condensate WTI, Cushing $65.34/bbl $69.62/bbl Gas Henry Hub $3.39/MMBTU $4.60/Mcf Dirección de Exploración y Extracción – Samaria-Luna y Bellota-Jujo Assets April 17, 2026 Page 6 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS The effects of derivative instruments designated as price hedges of oil and gas quantities are not reflected in DEE's individual property evaluations. Accumulated gas production imbalances, if any, were not taken into account in the proved gas reserves estimates reviewed. The proved gas volumes included herein do not include volumes of gas consumed in operations as reserves. Operating costs furnished by DEE are based on the operating expense reports of DEE and include only those costs directly applicable to the fields or wells for the properties reviewed by us. The operating costs include a portion of general and administrative costs allocated directly to the fields and wells. The operating costs furnished by DEE were accepted as factual data and reviewed by us for their reasonableness; however, we have not conducted an independent verification of the data used by DEE. No deduction was made for loan repayments, interest expenses, or exploration and development prepayments that were not charged directly to the fields, wells or contract areas. Development costs furnished by DEE are based on authorizations for expenditure for the proposed work or actual costs for similar projects. The development costs furnished by DEE were accepted as factual data and reviewed by us for their reasonableness; however, we have not conducted an independent verification of the data used by DEE. The estimated net cost of abandonment after salvage was included by Pemex for properties where abandonment costs net of salvage were material. Pemex's estimates of the net abandonment costs were accepted without independent verification. The proved undeveloped reserves for the properties reviewed by us have been incorporated herein in accordance with DEE's plans to develop these reserves as of December 31, 2025. The implementation of these development plans as presented to us is subject to the approval process adopted by DEE's management. As the result of our inquiries during the course of our review, DEE has informed us that the development activities for the properties reviewed by us have been subjected to and received the internal approvals required by DEE's management at the appropriate local, regional and/or corporate level. Additionally, DEE has informed us that they are not aware of any legal, regulatory or political obstacles that would significantly alter their plans. While these plans could change from those under existing economic conditions as of December 31, 2025, such changes were, in accordance with rules adopted by the SEC, omitted from consideration in making this evaluation. Current costs used by DEE were held constant throughout the life of the properties. DEE's forecasts of future production rates are based on historical performance from wells currently on production. If no production decline trend has been established, future production rates were held constant until a decline in ability to produce was anticipated. An estimated rate of decline was then applied until depletion of the reserves. If a decline trend has been established, this trend was used as the basis for estimating future production rates. Test data and other related information were used by DEE to estimate the anticipated initial production rates for those wells or locations that are not currently producing. For reserves not yet on production, sales were estimated to commence at an anticipated date furnished by DEE. Wells or locations that are not currently producing may start producing earlier or later than anticipated in DEE's estimates due to unforeseen factors causing a change in the timing to initiate production. Such factors may include delays due to weather, the availability of rigs, the sequence of drilling, completing and/or recompleting wells and/or constraints set by regulatory bodies. The future production rates from wells currently on production or wells or locations that are not currently producing may be more or less than estimated because of changes including, but not limited Dirección de Exploración y Extracción – Samaria-Luna y Bellota-Jujo Assets April 17, 2026 Page 7 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS to, reservoir performance, operating conditions related to surface facilities, compression and artificial lift, pipeline capacity and/or operating conditions, producing market demand and/or allowables or other constraints set by regulatory bodies. Ryder Scott did not evaluate the country and geopolitical risks in the country of Mexico where all of the subject properties are located. DEE's operations may be subject to various levels of governmental controls and regulations. These controls and regulations may include, but may not be limited to, matters relating to land tenure and use, drilling and production practices, environmental protection, marketing and pricing policies, various taxes and levies are subject to change from time to time. Such changes in governmental regulations and policies may cause volumes of proved reserves actually recovered and amounts of proved income actually received to differ significantly from the estimated quantities. The estimates of proved reserves presented herein were based upon a review of the subject properties; however, we have not made any field examination of the properties. No consideration was given in this report to potential environmental liabilities that may exist nor were any costs included by DEE for potential liabilities to restore and clean up damages, if any, caused by past operating practices. Certain technical personnel of DEE are responsible for the preparation of reserves estimates on new properties and for the preparation of revised estimates, when necessary, on old properties. These personnel assembled the necessary data and maintained the data and workpapers in an orderly manner. We consulted with these technical personnel and had access to their workpapers and supporting data in the course of our audit. DEE has informed us that they have furnished us all of the material accounts, records, geological and engineering data, and reports and other data required for this investigation. In performing our audit of DEE's forecast of future proved production, we have relied upon data furnished by DEE with respect to property interests, production and well tests from examined wells, normal direct costs of operating the properties, other costs such as transportation and/or processing fees, recompletion and development costs, development plans, abandonment costs after salvage, product prices based on the SEC regulations, adjustments or differentials to product prices, geological structural and isochore maps, well logs, core analyses, and pressure measurements. Ryder Scott reviewed such factual data for its reasonableness; however, we have not conducted an independent verification of the data furnished by DEE. The data described herein were accepted as authentic and sufficient for determining the reserves unless, during the course of our examination, a matter of question came to our attention in which case the data were not accepted until all questions were satisfactorily resolved. We consider the factual data furnished to us by DEE to be appropriate and sufficient for the purpose of our review of DEE's estimates of reserves. In summary, we consider the assumptions, data, methods and analytical procedures used by DEE and as reviewed by us appropriate for the purpose hereof, and we have used all such methods and procedures that we consider necessary and appropriate under the circumstances to render the conclusions set forth herein. Audit Opinion Based on our review, including the data, technical processes and interpretations presented by DEE, it is our opinion that the overall procedures and methodologies utilized by DEE in preparing their estimates of the proved reserves as of December 31, 2025 comply with the current SEC regulations and that the overall proved reserves in terms of barrels of oil equivalent (BOE) for the reviewed properties as estimated by DEE are, in the aggregate, reasonable within the established audit tolerance guidelines of 10 percent as set forth in the SPE auditing standards. Ryder Scott found the processes and controls

We were in reasonable agreement with DEE's estimates of proved reserves for the subject properties that we reviewed; although in certain cases there was more than an acceptable variance between DEE's estimates and our estimates due to a difference in interpretation of data. However notwithstanding, it is our opinion that on an aggregate basis the data presented herein for the subject properties that we reviewed fairly reflects the estimated net reserves owned by the United Mexican States.

RYDER SCOTT COMPANY PETROLEUM CONSULTANTS PETROLEUM RESERVES DEFINITIONS As Adapted From: RULE 4-10(a) of REGULATION S-X PART 210 UNITED STATES SECURITIES AND EXCHANGE COMMISSION (SEC) PREAMBLE On January 14, 2009, the United States Securities and Exchange Commission (SEC) published the "Modernization of Oil and Gas Reporting; Final Rule" in the Federal Register of National Archives and Records Administration (NARA). The "Modernization of Oil and Gas Reporting; Final Rule" includes revisions and additions to the definition section in Rule 4-10 of Regulation S-X, revisions and additions to the oil and gas reporting requirements in Regulation S-K, and amends and codifies Industry Guide 2 in Regulation S-K. The "Modernization of Oil and Gas Reporting; Final Rule", including all references to Regulation S-X and Regulation S-K, shall be referred to herein collectively as the "SEC regulations". The SEC regulations take effect for all filings made with the United States Securities and Exchange Commission as of December 31, 2009, or after January 1, 2010. Reference should be made to the full text under Title 17, Code of Federal Regulations, Regulation S-X Part 210, Rule 4-10(a) for the complete definitions (direct passages excerpted in part or wholly from the aforementioned SEC document are denoted in italics herein). Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. All reserve estimates involve an assessment of the uncertainty relating the likelihood that the actual remaining quantities recovered will be greater or less than the estimated quantities determined as of the date the estimate is made. The uncertainty depends chiefly on the amount of reliable geologic and engineering data available at the time of the estimate and the interpretation of these data. The relative degree of uncertainty may be conveyed by placing reserves into one of two principal classifications, either proved or unproved. Unproved reserves are less certain to be recovered than proved reserves and may be further sub-classified as probable and possible reserves to denote progressively increasing uncertainty in their recoverability. Under the SEC regulations as of December 31, 2009, or after January 1, 2010, a company may optionally disclose estimated quantities of probable or possible oil and gas reserves in documents publicly filed with the SEC. The SEC regulations continue to prohibit disclosure of estimates of oil and gas resources other than reserves and any estimated values of such resources in any document publicly filed with the SEC unless such information is required to be disclosed in the document by foreign or state law as noted in §229.1202 Instruction to Item 1202. Reserves estimates will generally be revised only as additional geologic or engineering data become available or as economic conditions change. Reserves may be attributed to either natural energy or improved recovery methods. Improved recovery methods include all methods for supplementing natural energy or altering natural forces in the reservoir to increase ultimate recovery. Examples of such methods are pressure maintenance, natural gas cycling, waterflooding, thermal methods, chemical flooding, and the use of miscible and immiscible displacement fluids. Other improved recovery methods may be developed in the future as petroleum technology continues to evolve. Reserves may be attributed to either conventional or unconventional petroleum accumulations. Petroleum accumulations are considered as either conventional or unconventional based on the nature of their in-place characteristics, extraction method applied, or degree of processing prior to sale.

PETROLEUM RESERVES DEFINITIONS Page 2 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS Examples of unconventional petroleum accumulations include coalbed or coalseam methane (CBM/CSM), basin-centered gas, shale gas, gas hydrates, natural bitumen and oil shale deposits. These unconventional accumulations may require specialized extraction technology and/or significant processing prior to sale. Reserves do not include quantities of petroleum being held in inventory. Because of the differences in uncertainty, caution should be exercised when aggregating quantities of petroleum from different reserves categories. RESERVES (SEC DEFINITIONS) Securities and Exchange Commission Regulation S-X §210.4-10(a)(26) defines reserves as follows: Reserves. Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering oil and gas or related substances to market, and all permits and financing required to implement the project. Note to paragraph (a)(26): Reserves should not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that are clearly separated from a known accumulation by a non-productive reservoir (i.e., absence of reservoir, structurally low reservoir, or negative test results). Such areas may contain prospective resources (i.e., potentially recoverable resources from undiscovered accumulations). PROVED RESERVES (SEC DEFINITIONS) Securities and Exchange Commission Regulation S-X §210.4-10(a)(22) defines proved oil and gas reserves 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 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. PETROLEUM RESERVES DEFINITIONS Page 3 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS PROVED RESERVES (SEC DEFINITIONS) CONTINUED (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 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. RYDER SCOTT COMPANY PETROLEUM CONSULTANTS PETROLEUM RESERVES STATUS DEFINITIONS AND GUIDELINES As Adapted From: RULE 4-10(a) of REGULATION S-X PART 210 UNITED STATES SECURITIES AND EXCHANGE COMMISSION (SEC) and 2018 PETROLEUM RESOURCES MANAGEMENT SYSTEM (SPE-PRMS) Sponsored and Approved by: SOCIETY OF PETROLEUM ENGINEERS (SPE) WORLD PETROLEUM COUNCIL (WPC) AMERICAN ASSOCIATION OF PETROLEUM GEOLOGISTS (AAPG) SOCIETY OF PETROLEUM EVALUATION ENGINEERS (SPEE) SOCIETY OF EXPLORATION GEOPHYSICISTS (SEG) SOCIETY OF PETROPHYSICISTS AND WELL LOG ANALYSTS (SPWLA) EUROPEAN ASSOCIATION OF GEOSCIENTISTS & ENGINEERS (EAGE) Reserves status categories define the development and producing status of wells and reservoirs. Reference should be made to Title 17, Code of Federal Regulations, Regulation S-X Part 210, Rule 4- 10(a) and the SPE-PRMS as the following reserves status definitions are based on excerpts from the original documents (direct passages excerpted from the aforementioned SEC and SPE-PRMS documents are denoted in italics herein). DEVELOPED RESERVES (SEC DEFINITIONS) Securities and Exchange Commission Regulation S-X §210.4-10(a)(6) defines developed oil and gas reserves as follows: 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. Developed Producing (SPE-PRMS Definitions) While not a requirement for disclosure under the SEC regulations, developed oil and gas reserves may be further sub-classified according to the guidance contained in the SPE-PRMS as Producing or Non-Producing. Developed Producing Reserves Developed Producing Reserves are expected quantities to be recovered from completion intervals that are open and producing at the effective date of the estimate. PETROLEUM RESERVES STATUS DEFINITIONS AND GUIDELINES Page 2 RYDER SCOTT COMPANY PETROLEUM CONSULTANTS Improved recovery reserves are considered producing only after the improved recovery project is in operation. Developed Non-Producing Developed Non-Producing Reserves include shut-in and behind-pipe Reserves. Shut-In Shut-in Reserves are expected to be recovered from: (1) completion intervals that are open at the time of the estimate but which have not yet started producing; (2) wells which were shut-in for market conditions or pipeline connections; or (3) wells not capable of production for mechanical reasons. Behind-Pipe Behind-pipe Reserves are expected to be recovered from zones in existing wells that will require additional completion work or future re-completion before start of production with minor cost to access these reserves. In all cases, production can be initiated or restored with relatively low expenditure compared to the cost of drilling a new well. UNDEVELOPED RESERVES (SEC DEFINITIONS) Securities and Exchange Commission Regulation S-X §210.4-10(a)(31) defines undeveloped oil and gas reserves as follows: 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 paragraph (a)(2) of this section, or by other evidence using reliable technology establishing reasonable certainty.
