PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 2 of 128 [105000] Management commentary Management commentary [text block] In addition to this document, the Company publishes a report disclosing its preliminary financial and operating results as of September 30, 2025. Readers are encouraged to review this report alongside the present document. The report is accompanied by a series of exhibits, as well as the stenographic transcript of the Company’s earnings conference call held on October 27, 2025. All materials — including the report, exhibits, transcript, and other relevant documents — are available for download at www.pemex.com/en/investors. Information Summary Third Quarter 2025 During the third quarter of 2025 (3Q25), Petróleos Mexicanos (PEMEX) operated in an environment characterized by pressure on international crude prices and technical challenges arising from the natural decline of strategic fields. Within this context, the company maintained resilient operations and delivered solid results in production, refining, and financial discipline. Average production of liquid hydrocarbons was 1.65 million barrels per day, while natural gas output reached 3,730 million cubic feet per day, driven by a 5.8% increase in non-associated gas following the incorporation of new wells in the Ixachi field. Crude processing averaged 1.009 million barrels per day, representing an annual increase of 4.8%, supported by the continuous operation of the National Refining System and the Olmeca Refinery. Production of refined products totaled 1.001 million barrels per day, with a high-value distillate yield of 62%. In line with these operational trends, sales and service revenues totaled MXN 378.9 billion, a decrease of 11.1% year-over-year, mainly due to lower export volumes and reduced crude prices. However, cost of sales declined by 10.3%, partially offsetting the impact on operating results. These combined factors resulted in a gross profit of MXN 37 billion in 3Q25 and an improvement of nearly MXN 100 billion in net results compared to the same period in 2024. The company’s financial balance showed signs of stability. As of September 30, 2025, total debt stood at USD 100.3 billion, reflecting a marginal increase of 2.7%, mainly related to a repo transaction to address short-term maturities. PEMEX maintains available credit lines of USD 4.2 billion and MXN 20.5 billion, supporting its liquidity capacity. The company also sustained a steady pace of payments to suppliers and launched the 2025 Investment Financing Program, supported by a financial vehicle with a capacity of up to MXN 250 billion, aimed at strengthening the supply chain and enhancing operational efficiency. From an environmental standpoint, CO2 emissions increased by 15.4% due to gas-processing venting, while methane emissions rose 25% as a result of higher flaring in new wells. Sulfur oxide (SO?) emissions remained stable. In industrial safety, the frequency index stood at 0.29 accidents per million man-hours, a 17% reduction year-over-year. On the social front, MXN 639 million were allocated to 85 programs and initiatives across 12 states. PEMEX continues to advance the implementation of its Comprehensive Capitalization and Financing Strategy, designed and executed in coordination with the Ministry of Finance and Public Credit (SHCP) and the Ministry of Energy (SENER), as outlined in the Strategic Plan 2025–2035 presented in August. During the quarter, key operations were consolidated, including the repurchase

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 3 of 128 of bonds for up to USD 9.9 billion and a repo transaction of USD 11.3 billion. In addition, the Federal Government contributed over MXN 253 billion in equity, strengthening liquidity and reducing financial costs. These financial operations are expected to reduce short-term debt by approximately 32% and total debt by around 10% by year- end. Together with improved liquidity and access to competitive financing, these measures are set to enhance profitability and support the development of strategic productive projects. PEMEX reaffirms its ability to adapt and evolve, contributing consistently to the strengthening of Mexico’s energy sector.

Disclosure of entity's most significant resources, risks and relationships [text block] When evaluating the potential acquisition of securities from PEMEX, potential investors must consider all the information included in the company's Report, and specially, the risk factors hereby mentioned. These risks could significantly affect PEMEX's performance and profitability but are not the only risks the Company faces. Risks described in this document are the ones PEMEX is currently aware of and that it considers relevant. In addition, other risks may exist or emerge in the future and influence the price of the company's securities. 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. 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 the first nine-month period ended September 30, 2025, we received support from the Mexican Government mainly to strengthen our financial condition, such additional support may not be available in upcoming years. As of September 30, 2025, our total indebtedness, including accrued interest, was Ps. 1,843.5 billion (U.S.$ 100.3 billion), in nominal terms, which represented a 6.8% 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 September 30, 2025, 51.9% of our existing debt, or Ps. 877.8 billion (U.S.$ 47.8 billion), including accrued interest, is scheduled to mature in the next three years, including Ps. 125.8 billion (U.S.$ 6.8 billion) scheduled to mature in 2025. Our working capital deteriorated 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. 463.8 billion (U.S.$ 25.2 billion) as of September 30, 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 the first nine-month period ended September 30, 2025, we received Ps. 380.1 billion (U.S.$ 20.7 billion) in capital contributions from the Mexican Government to improve our financial position and for the Proyectos Aprovechamiento de

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 5 of 128 Residuales en las Refinerías Miguel Hidalgo and Salina Cruz, Oaxaca. These contributions represented an important source for the payment of our debt during the first nine-month period ended September 30, 2025. If we were unable to obtain financing on favorable terms, 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 be further magnified if support from the Mexican Government were to be discontinued or reduced. 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, 2024, 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 condensed consolidated interim financial statements not audited have been prepared on the assumption that we will continue as a going concern. Our condensed consolidated interim financial statements not audited as of September 30, 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 condensed consolidated interim financial statements not audited as of the first nine-month period ended September 30, 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 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 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. Two of such rating agencies have assigned us a non-investment grade rating, and the other agency assigned us an investment grade rating. However, in 2025, two of the three rating agencies raised PEMEX's long-term rating, improving its outlook and reflecting the Mexican government's increased commitment to supporting its financial obligations and the publication of its 2025-2035 Strategic Plan.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 6 of 128 While these downgrades do not constitute a default or an event of default under our debt instruments, they have increased our cost of financing. Further downgrades may have material adverse consequences on our ability to access financial markets and the terms on which we may obtain financing, including further increases in our cost of financing. In turn, this 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. Should this trend continue, we could face greater financial limitations that would affect our ability to meet our debt obligations and maintain our long-term sustainability. 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) trading activity in oil and natural gas 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 the first nine-month period ended September 30, 2025, and 2024, the weighted average Mexican crude oil price remained volatile due to market conditions, averaging U.S. $63.22 per barrel, and U.S. $72.48, respectively. As of the date of this report, prices of crude oil remain highly volatile as a result of geopolitical uncertainty. 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” below. 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. Our income and cash flows depend on the prices of crude oil, petroleum products and natural gas. Oil prices are highly sensitive to actual 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. The volatility of global oil, natural gas and refined products prices could increase due to an increase, or the threat of an increase, in military or paramilitary activities such as the ongoing war in Ukraine and the conflict between Israel, Hamas, Hezbollah and Iran in the Middle East, as well as the interventions of the United States; disruptions in critical supply routes such as disruptions on operations in the Red Sea and the Suez Canal and; the effects of international sanctions and trade restrictions that reduce crude oil supply in global

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 7 of 128 markets. Any destabilization in energy markets could reduce the price we receive from our sales and adversely affect our profitability. Increases in oil, gas and refined products prices resulting from these conflicts may not persist and could be reversed by factors beyond our control, including geopolitical events. 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 demand the redesign of 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 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, 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” 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, and the illegal trade of hydrocarbons, such as those introduce into the country through tax evasion. Such criminal activity has led to fires, explosions, property and environmental damage, injuries and loss of life, as well as loss of revenue from the stolen products. The actions we have taken in conjunction with the Mexican Government to reduce the illicit market of fuels have not produced sustained improvement in recent years. In 2024 and 2023, we discovered 11,774 and 14,890 illegal pipeline taps, respectively. We are also exposed to the risk that some of our employees may and other public servers, or may be perceived to be participating in the illicit market in fuels. In addition, our facilities are exposed to intentional acts of sabotage, terrorism, blockades, theft and piracy. The occurrence of incidents such as these related to the production, processing and transportation of oil and gas products could result in personal injuries, loss of life, environmental damage from the subsequent containment, clean up and repair expenses, equipment damage and damage to our facilities, which in turn could adversely affect our business, results of operations and financial condition. We are exposed to cybersecurity incidents and attacks that could significant adversely affect our business, results of operations and financial condition. Our operations rely on information technology and operational systems. In recent years, cyber-threats and cyber-attacks targeting critical infrastructure in the energy sector have become more sophisticated, frequent, coordinated and costly, affecting our operations and information technology systems. These attacks seek to generate vulnerabilities in business and industrial

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 8 of 128 systems and equipment, disrupting business continuity and compromising sensitive data. If the integrity of our information technology and operational 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 lost or stolen. 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 personal, customer or partner data, (iv) reputational damage and loss of trust, (v) decreased revenues and financial losses, theft or alteration of information, depending on the severity 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 2024, our total proven reserves had a decrease of 29.8 million barrels of crude oil equivalent, or 0.4%, after accounting for discoveries, extensions, revisions, and delimitations, from 7,480.4 million barrels of crude oil equivalent as of December 31, 2023, to 7,450.6 million barrels of crude oil equivalent as of December 31, 2024. Based on these numbers, our reserve replacement ratio (“RRR”) in 2024 was 96.6%, a decrease as compared to a RRR of 103.2% in 2023. Our proven reserves decreased from 7,480.4 million barrels of crude oil equivalent as of December 31, 2023, to 7,450.6 million barrels of crude oil equivalent as of December 31, 2024, due to discoveries, developments, delineations and revisions of our proved reserves, in particular to the recategorization of reserves due to drilling of development wells. Our crude oil production decreased by 6.1% in 2024, mainly due to the natural decline of some of our main fields such as: Zaap, Quesqui, 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 and climate action— may result in the recognition of impairment charges in certain of our assets. Due to variations in the price of crude oil and 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 September 30, 2025, and 2024 we recognized an impairment charge in the amount of Ps. 52.6 billion and Ps. 51.8 billion, respectively. 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.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 9 of 128 Competition in the energy sector could adversely affect our business and financial performance. The Mexican Constitution and the Ley del Sector de 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 production activities, and the import and sale of gasoline. Accordingly, we face competition for the right to explore and develop new oil and gas reserves. 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 in 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. 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 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 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 been insufficient in the past and could 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 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 condensed consolidated interim financial statements not audited 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. We participate in strategic alliances and other joint arrangements, which may not always perform as expected, and harm our reputation, 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

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 10 of 128 in oil and gas exploration and production, 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 contracts, 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 information requirements 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 adverse 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 restrict 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 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” below. Risk Factors Related to our Relationship with the Mexican Government The Mexican Government controls us, could transfer or reorganize our assets, 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 Ley de la Empresa Pública del Estado, Petróleos Mexicanos (2025 Petróleos Mexicanos Law), we were transformed from a productive state-owned company to a state-owned public company on November 1, 2024. The 2025 Petróleos Mexicanos Law establishes 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 additional autonomy with respect to our budget. Notwithstanding this autonomy, 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. 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. Despite being wholly owned by the Mexican Government and receiving financial contributions to address our debt, our financial obligations do not constitute 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.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 11 of 128 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. 380.1 billion (U.S.$20.6 billion) as of the nine-month period ended September 30, 2025, mainly to strengthen our financial condition. 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, it may cease to provide such support 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 nine-month period ended September 30, 2025, our total taxes and duties were Ps. 156.9 billion, representing 13.5% 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, such as tax credits related to the Derecho por la Utilidad Compartida (Profit-Sharing Duty or “DUC”) or temporary suspensions of the collection thereof, 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 “Federal Revenue Law”) was published in the Diario Oficial de la Federación (the “Official Gazette of the Federation”). The Federal Revenue Law introduced changes to our fiscal regime and the Mexican Government may implement further changes in the future. 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.” 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. 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 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

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 12 of 128 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. 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 U.S. Securities and Exchange Commission (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. 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. 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. 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” below. 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 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, expert interpretation and subjective judgment. Additionally, estimates may be revised based on subsequent results of drilling, testing and production. These estimates are also subject to certain adjustments for changes in variables, including crude oil prices. Therefore, proved reserves estimates may differ significantly from the ultimately extract and recoverable quantities of crude oil and natural gas. 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

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 13 of 128 value of the hydrocarbon reserves that we have the right to extract and sell” above. We revise our hydrocarbon reserve estimates annually, which may result in material revisions to estimates contained in this report. Our ability to maintain our long-term growth objectives for oil 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 condensed consolidated interim financial statements not audited 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 administration 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” below. 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 taxes and duties 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 lower 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

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 14 of 128 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” above. 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. Moreover, we cannot assure you 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 perform as expected, and could harm our reputation, could have an adverse effect on our business, results of operations and financial condition” above. The Mexican Government has historically imposed price controls in the domestic market on our products. The Mexican Government has from time-to-time imposed price controls 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 have not always been able to fully pass on price increases to our customers in the domestic market. In 2017, the Mexican Government began gradually removing price controls on gasoline and diesel as part of the liberalization of fuel prices in Mexico. As of the date of this report, sales prices of gasoline and diesel are determined by the free market. However, control mechanisms have been established, such as the agreement issued by the Federal Executive, which establishes a maximum price per liter for regular gasoline. We do not have control over the Mexican Government’s domestic policies, and the Mexican Government could reintroduce price controls in the domestic market in the future. The imposition of such price controls would adversely affect our results of operations 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 social developments in Mexico could adversely affect our business and financial condition. These circumstances 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, and ability to service our debt. See “Risk Factors — Risk Factors Related to our Relationship with the Mexican Government—The Mexican Government controls us, could transfer or reorganize our assets, or may limit our ability to satisfy our external debt obligations” above. 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 support from the Mexican Government. A deterioration in international financial or economic conditions, whether due to a slowdown in growth 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.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 15 of 128 Federal elections were held in Mexico and in the United States on June 2, 2024, and November 5, 2024, respectively. In Mexico, Claudia Sheinbaum Pardo was elected president and assumed office on October 1, 2024. In the United States, Donald J. Trump won the election and assumed the presidency on January 20, 2025. Economic conditions in Mexico are highly correlated with economic conditions in the United States due to geographic proximity and the high degree of commercial and economic interdependence between the two countries. Accordingly, political developments in the United States, including changes in American administrations and U.S. government policies, including fiscal, tariff, immigration policies, among others, can influence the exchange rate between the U.S. dollar and the Mexican peso and adversely affect economic conditions in Mexico. In addition, given that the Mexican economy is heavily related with the U.S. economy, policies that are unfavorable to Mexico or a deterioration in U.S.-Mexico relations may adversely affect Mexico’s economy. We cannot provide any assurances that political developments in Mexico and the United States, over which we have no control, will not have a material adverse effect on our results of operations and financial condition, including our ability to repay our debt. Changes in global trade policy could adversely the Mexican economy and, in turn, our operations and financial condition. During the first nine-month period ended September 30, 2025, our export sales to the United States amounted to Ps. 322.7 billion, which represented 27.7% of our total revenues and 75.2% of our export sales for the year. With limited exceptions, exports of petrochemical products from Mexico to the United States have been free or exempt from tariffs since 2003 under the North American Free Trade Agreement and the United States-Mexico-Canada Agreement (the “USMCA”) that replaced it on July 1, 2020. While petrochemical exports from Mexico to the United States remain exempt from tariffs under the USMCA, any shift in trade relations among Mexico, the United States and Canada resulting from the implementation of tariffs or the renegotiation of the USMCA could require us to renegotiate our contracts or lose business, which could in turn result in a material adverse impact on our business and results of operations. During 2025, the U.S. government has made changes to its international trade policy and, in some cases, has expressed interest in renegotiate or potentially terminate certain existing trade agreements. In addition, the U.S. government recently imposed tariffs on certain goods, including steel and aluminum, affecting several sectors; has announced new baseline tariffs applicable to all of its trading partners and has indicated a willingness to impose tariffs on other products, including a possible raising tariffs on imports from Mexico. In response, Mexico has considering the possibility of reciprocal responses, but not yet enacted or confirmed, in imposing tariffs on certain U.S. products. Disruptions to global trade, the introduction of barriers and bilateral frictions, together with any future downturns in the global economy resulting therefrom, could adversely affect our financial condition, results of operations and ability to repay our debt. The macroeconomic environment in which we operate is beyond our control and may become less favorable in the future. There can be no assurances that the USMCA will not be renegotiated, nor that U.S.-Mexico trade relations will not deteriorate and result in the imposition of trade barriers on the products that we produce and sell. A trade dispute between the United States and Mexico may have negative effects on the Mexican economy, exchange rates, inflation and economic prospects, which may in turn negatively affect our business and results of operations. Mexico has experienced a period of heightened criminal activity, which could affect our operations. In recent years, Mexico has experienced a period of heightened criminal activity, primarily due to the activities of drug cartels and related criminal organizations. Particularly, the development of an illicit fuel market in Mexico has led to heightened theft and illegal trading of fuels that we produce, as well as the 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. However, criminal activity remains prevalent in Mexico and is likely to persist. In this regard, crimes involving the theft and trade of hydrocarbons with tax evasion have been identified. Criminal activities, along with the associated damage to human life and

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 16 of 128 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 administration 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. The political coalition led by Mexico’s National Regeneration Movement (Movimiento de 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 new Congress assumed office on September 1, 2024, and the new 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 Pemex’s ability to meet its 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. 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. 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 lead to substantial fines, operational restrictions, and adversely affect our profitability and financial performance. 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.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 17 of 128 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, droughts, extreme weather conditions, among others; 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 and limit our ability to invest in strategic projects. 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 greenhouse gas emissions, 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 boost a shift in consumer demand from petroleum-based fuels toward lower-carbon alternatives, adversely affecting our operations, financial results and long-term viability. 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 in favorable terms. In addition, global decarbonization could negatively impact on 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 possible structural changes in the market, such as sharp drops in hydrocarbon product prices. All 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. 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 U.S. regulators have in past years called for increased ESG disclosure, it is expected that federal ESG-related regulations under the current U.S. presidential administration will deprioritize disclosure or mandate the abandonment of ESG programs, while regulations at the state level will vary. For fiscal year 2025, we have to file with the Bolsa Mexicana de Valores, S. A. B. de C. V. (Mexican Stock Exchange) an ESG report in accordance with IFRS S1 about Sustainability and IFRS S2 about Climate. Failure to adapt to or comply with regulatory requirements or evolving investor or stakeholder expectations and standards for ESG practices may harm our reputation and ability to access capital, which may, in turn, have an adverse impact on our results of operation and financial condition.

Disclosure of results of operations and prospects [text block] Operating Summary Liquid hydrocarbon production During 3Q25, liquid hydrocarbons averaged 1,656 thousand barrels per day (Mbd), representing a decrease of 120 Mbd compared with the previous quarter. In the same period, crude oil production averaged 1,648 Mbd, 116 Mbd lower than in 3Q24, mainly due to the natural decline of mature fields and delays in the installation of offshore infrastructure. Of total output, 64% came from offshore fields and 36% from onshore fields, while the Ku-Maloob-Zaap, Cantarell, and Abkatún-Pol Chuc assets accounted for 68% of national crude oil production. Hydrocarbon gas production reached 3,730 MMcfd, a decrease of 19 MMcfd compared with 2024. This reduction was partially offset by the start-up of the Bakté field and the incorporation of new wells in Ixachi. Non-associated gas production increased by 110 MMcfd, equivalent to a 5.8% rise versus the previous year. Crude oil processing and petroleum production Crude oil processing averaged 1,009 Mbd, a 4.8% increase compared to the same quarter in 2024. This increase is primarily due to the sustained operational performance of NRS, further enhanced by the commissioning of two processing trains at the Olmeca refinery. Similarly, petroleum product output rose by 7.6% to reach 1,001 Mbd, of which 62.0% were high-value distillates (gasoline, diesel, and jet fuel). Gas processing and production During 3Q25, wet gas processing averaged 2,230 MMcfd, a decrease of 44 MMcfd compared with the same period of 2024. This variation resulted from higher production in the Southeast Region and lower output from the Burgos asset.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 20 of 128 Dry gas production averaged 1,747 MMcfd, down 29 MMcfd from 3Q24, mainly due to reduced feedstock availability at the Cactus, Ciudad Pemex, and Burgos gas processing complexes.

EXPLORATION AND EXTRACTION 3Q25 Crude oil Production Maintaining base production and incorporating new output remain key factors in meeting operational targets and strengthening the company’s long-term viability. In this context, well interventions continue to be essential activities to sustain and increase hydrocarbon production. During 3Q25, PEMEX maintained its strategy to preserve base production through 379 minor repairs and 161 stimulations. Additionally, 20 well completions and 35 major repairs were carried out to incorporate incremental production. As a result, crude oil production, including partner volumes, averaged 1,648 Mbd, representing a decline of 116 Mbd compared with the same quarter of 2024. This performance mainly reflected the natural decline of the Quesqui, Tupilco Profundo, Zaap, and Maloob fields; increased operational complexity in high-pressure, high-temperature (HPHT) wells; delays in offshore infrastructure installation at the Xanab and Quesqui fields; and atypical weather conditions that temporarily affected offshore operations. Of total production, 64% corresponded to shallow-water fields and 36% to onshore fields. By crude type, 50% was heavy, 24% light, 10% super light, and 16% condensate. The Ku-Maloob-Zaap, Cantarell, and Abkatún-Pol Chuc assets accounted for 68% of total crude oil production. Hydrocarbon Gas Production During 3Q25, hydrocarbon gas production averaged 3,730 MMcfd, a decrease of 19 MMcfd compared with the same period of 2024, attributable to the natural decline of mature fields and delays in infrastructure development in producing areas, which limited the capacity to offset the reduction in volumes. Of total hydrocarbon gas output, 35% came from shallow-water fields and 65% from onshore fields.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 21 of 128 The start-up of the Bakté field and new wells in Ixachi helped partially mitigate this decline, reflecting progress in the onshore production strategy. Non-associated gas production increased by 110 MMcfd (5.8%), mainly driven by higher volumes from Ixachi and other onshore fields. Of total non-associated gas production, 35% originated from shallow-water fields and 65% from onshore areas. Gas Utilization During 3Q25, gas utilization reached 93.0%, a decrease of 2.1 percentage points compared with the same period of 2024. This variation was concentrated in the Southern Region due to gas rejection at the Nuevo Pemex Gas Processing Complex, which faced limitations in processing sour wet gas from the Bakté field. Infrastructure During 3Q25, 16 development wells were completed, 11 fewer than in the same period of 2024. Regarding exploratory wells, 4 were completed, representing a decrease of two wells compared with the third quarter of the previous year. Discoveries During 3Q25, the analysis of three exploratory wells in the Marina Sur and Terrestre Sur assets revealed significant potential in preliminary 3P reserves. The Xomili-1 well, located in the Uchukil project, is in the evaluation stage and produces 35° API oil, with an estimated 12 MMboe in 3P reserves. Meanwhile, the Iklum-1A well, in the Cuichapa project, was a producer of 45° API gas condensate, with an estimated 111 MMboe in 3P reserves — making it the largest contributor. Finally, the Bakte-1DEL well, part of the Comalcaco project, provides an additional preliminary 3P reserve estimate of 17 MMboe. Altogether, the combined preliminary estimate amounts to approximately 140 MMboe, consolidating an opportunity to increase the reserve base and strengthen future production.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 22 of 128 INDUSTRIAL PROCESSES 3Q25 Crude Oil Processing In the third quarter of 2025, crude oil processing in the National Refining System (NRS) averaged 1,009 Mbd, a 47 Mbd increase (4.8%) compared to the same quarter in 2024. This increase is primarily due to the sustained operational performance of NRS, further enhanced by the commissioning of two processing trains at the Olmeca refinery. Petroleum Products Production In the third quarter of 2025, petroleum product output averaged 1,001 Mbd, a 71 Mbd increase (7.6%) compared to the same period in 2024. The production basket included 344 Mbd of gasoline, 235 Mbd of diesel, 42 Mbd of jet fuel, and 380 Mbd of other petroleum products and LPG. In this regard, the yield of gasoline, diesel, and jet fuel increased by 9.3 percentage points compared to the same period in 2024, rising from 52.7% to 62.0%, as a result of improved reliability of processing plants due to the rehabilitation program of the NRS. PEMEX Service Stations As of September 30, 2025, a total of 7,358 service stations were operating under the PEMEX Franchise, representing a 1% increase compared to the same date in 2024. Of these, 7,171 stations are operated by third parties, while 45 are owned by PEMEX and serve as self-consumption stations. Additionally, 1,155 service stations were operating under a brand sublicensing scheme, and 6,274 stations operated under non-PEMEX brands, supplied either by PEMEX or through direct imports. Related parties Related parties include individuals and companies that do not form part of PEMEX, but that could take advantage of being in a privileged position as a result of their relation with PEMEX. Also included are situations in which PEMEX could take advantage of a special relationship in order to benefit its financial position or results of operations. Mrs. Emilia Esther Calleja Alor, Chief Executive Officer of CFE, was appointed member of the Board of Directors of Petróleos Mexicanos in accordance with the Article 18 Fraction V of the Ley de la Empresa Pública del Estado, Petróleos Mexicanos. CFE has executed several purchase agreements with Industrial Processes and Energy Transformation. As of September 30, 2025, the amount of operations held is Ps. 24.2 billion and the balance receivable is Ps. 8.8 billion. Natural Gas Processing and Production During 3Q25, the processing of wet gas averaged 2,230 MMcfd, a decrease of 44 MMcfd compared to the same period in 2024. This variation reflects a 31 MMcfd increase in sour wet gas production in the Southeast region, offset by a 78 MMcfd decline in sweet wet gas production in the Northern region, mainly from the Burgos asset. The production of dry gas averaged 1,747 MMcfd, 29 MMcfd lower year over year, due to reduced availability at the Cactus, Ciudad Pemex, and Burgos Gas Processing Complexes. Regarding gas liquids, production declined by 28 Mbd, primarily impacted by lower output at Nuevo Pemex and Burgos. Finally, the processing of condensates averaged 9 Mbd, nearly 5 Mbd lower than in the same period last year, mainly due to lower receipts of both sour and sweet condensates.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 23 of 128 Environmental, Social & Governance Criteria 3Q25 Environmental Carbon Dioxide Equivalent Emissions During 3Q25, carbon dioxide equivalent (CO2e) emissions reached 16.5 MMt, representing an increase of 15.4% compared to the same period in 2024. Although the partial restoration of cogeneration steam supply at one of the gas processing complexes helped to limit flaring, this source of emissions remains present. By the end of August, the National Natural Gas Control Center (CENAGAS) authorized a higher volume of gas injection into distribution pipelines in Veracruz, which will help reduce flaring in the Exploration and Extraction (E&E) region. However, emissions in the area remained above typical levels during the quarter. Methane Emissions During the period, methane emissions totaled 179.8 Mt, a 25% increase compared to the same period in 2024, mainly due to incomplete combustion in flare systems, higher volumes of gas sent to these systems, and the incorporation of new wells in Exploration and Extraction. Sulfur Oxide Emissions During the quarter, sulfur oxide (SO?) emissions amounted to 327 Mt, a 0.1% reduction compared to the same period in 2024. This result reflects improvements in recovery systems at refining facilities, progress in the rehabilitation of gas processing operations, and continued reductions in Exploration and Extraction. Water Reuse During 3Q25, the ratio of reused water to total water use decreased by 36.6% compared to the same period in 2024, reflecting a 38% reduction in the volume of reused water (7.21 MMm³). Although water reuse increased at the wastewater treatment plants in Salamanca (49%) and Tula (6%), these gains did not offset declines at the Madero and Cadereyta facilities, where operational failures and pending rehabilitation work significantly reduced treatment capacity. Energy Consumption During 3Q25, total energy consumption amounted to 119.9 petajoules (PJ), a 4.2% decrease compared to the same period in 2024, mainly due to lower extraction and crude processing volumes, which declined by 6.0% and 4.0%, respectively. Initiatives for Atmospheric Emissions Reduction and Climate Change Adaptation  Emissions Trading System (ETS). During the quarter, the facilities participating in the pilot phase of the ETS completed the submission of verified inventory reports. The Advisory Committee resumed its sessions to review proposals for the operational phase, which will continue into the fourth quarter.  Greenhouse Gas (GHG) Emissions. Maintenance work on sour vapor recovery systems advanced across logistics operations, helping to eliminate one of the main sources of GHG emissions. By 3Q25, the intermittent operation of these systems has enabled a significant reduction in emissions, including in refining and petrochemical processes.  Gas Utilization. Infrastructure for gas handling and recovery in Exploration and Extraction was strengthened, highlighting the rehabilitation of compressors, the commissioning of new facilities, and the reactivation of boosters.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 24 of 128  Methane Emissions. Leak detection and repair programs continued in offshore and onshore facilities, in compliance with ASEA regulations. As part of the “Zero Routine Flaring by 2030” initiative, PEMEX presented projects with potential to reduce emissions to the World Bank, following technical visits to Bellota, Paredón, and Tula.  Climate Change Adaptation. Climate risk assessments were completed for the Burgos, Arenque, and Poza Rica Gas Processing Complexes (CPG), while similar studies advanced at the Matapionche and Ciudad Pemex CPGs, as well as at the Cangrejera Petrochemical Complex and the Salamanca, Minatitlán, Tula, and Cadereyta refineries.  Follow-up on the Critical Risk Management Program. Of the 240 identified environmental risks, 27.9% have been resolved, 25% are in progress, and 26.3% have active work plans. Among Priority 1 risks, 51.2% have been addressed, 31.7% (13) are in progress, and 9.8% (4) are in the contracting stage. The estimated investment for their comprehensive mitigation amounts to Ps. 15.5 billion, focused on reducing impacts on soil, water, and air. Social Occupational Health and Industrial Safety PEMEX reaffirms its commitment to comprehensive risk management through the continuous strengthening of its industrial safety and occupational health systems. The corporate strategy focuses on the identification, assessment, and control of critical risks, with an emphasis on incident prevention and the protection of strategic assets. These actions contribute to ensuring safe operations, operational continuity, and the safeguarding of human capital, in alignment with the company’s principles of sustainability and corporate responsibility. Frequency Index As of 3Q25, the frequency index for PEMEX personnel stood at 0.29 accidents per million man-hours worked with exposure to risk, a 17% decrease compared to the 0.35 recorded in the same period of the previous year. During the third quarter, 27 workers were injured across various PEMEX business lines.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 28 of 128 Open Data: PEMEX coordinated with the Digital Transformation and Telecommunications Agency to update and align its databases with the national open data platform. Technical meetings were held to define mechanisms for uploading and consolidating information. Transparency Initiatives: PEMEX maintained its participation in the Extractive Industries Transparency Initiative, addressing requests from the International Secretariat and participating in meetings convened by the national technical working group in follow-up to the 2025 work plan. Institutional Policy Framework: The process to update internal policies and guidelines on transparency, access to information, and personal data protection was initiated, with the objective of aligning them with newly issued legal requirements. Transparency Obligations: As of the end of the second quarter, 7,617,737 data records were reported on the National Transparency Platform. The upload corresponding to the third quarter was scheduled for October, in accordance with applicable guidelines. Financial position, liquidity and capital resources [text block] Financial Summary Revenues In the third quarter of 2025, sales and service revenues amounted to Ps. 378.9 billion, an 11.1% decrease as compared to the same period in 2024. This variation is mainly due to lower export sales, driven by reduced crude oil volumes and lower prices, as well as a decline in domestic sales attributable to lower volumes of Magna gasoline, diesel, and fuel oil. Cost of Sales The cost of sales, including fixed assets impairment, recorded Ps. 341.6 billion, a 10.3% decrease as compared to the same quarter of the previous year. This decrease is mainly explained by lower purchases of products for resale, the elimination of extraction and exploration duties, and a smaller variation in inventories, partially offset by an increase in taxes on domestic sales. Taxes and Duties During 3Q25, PEMEX incurred Ps. 47.7 billion in taxes and duties, including the Welfare Oil Duty. This contrasts with a tax credit of Ps. 6.0 billion recorded in 3Q24. The change is largely explained by the fiscal stimulus applied in 2024, which granted a 100% credit on provisional payments of the Profit-sharing Dury (DUC) from May to July. Net Result In the quarter, PEMEX recorded a Ps. 61.2 billion net loss, lower than the loss recorded in 3Q24 (Ps. 161.5 billion). The improvement was mainly due to lower cost of sales, reduced impairment of fixed assets, and a foreign exchange gain of Ps. 33.4 billion, driven by the depreciation of the U.S. dollar against the Mexican peso.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 29 of 128 These effects were partially offset by lower sales, higher impairment of financial assets, derivative losses, and increased taxes. Financial Debt As of September 30, 2025, total financial debt recorded U.S. $ 100.3 billion. Translated at an exchange rate of Ps. 18.3825 per U.S. $ 1.00, this amounts to approximately Ps. 1,843 billion. Financial Resources PEMEX has revolving credit facilities for liquidity management of up to U.S. $ 5.7 billion and Ps. 20.5 billion. As of September 30, 2025, U.S. $ 4.2 billion and Ps. 20.5 billion were available. EBITDA EBITDA amounted to Ps. 58.4 billion, a Ps. 27 billion decrease as compared to the third quarter of 2024. CAPEX As of September 30, 2025, capital expenditure amounted to Ps. 110.6 billion. Consolidated Income Statement from July 1 to September 30, 2025 Total Revenues from Sales and Services Total sales and services revenue amounted to Ps. 378.9 billion, representing an 11.1% decrease compared to the third quarter of 2024. This variation was primarily driven by:  a 21.5% decrease in export sales value, mainly due to lower crude oil export volumes and lower prices; and  a 4.2% decrease in domestic sales, due to a volume decrease in magna value, resulting from lower sales volumes of regular gasoline, diesel, and fuel oil sold. Cost of Sales Cost of sales, including fixed asset impairment, totaled Ps. 341.6 billion, a 10.3% decrease. This variation was primarily driven by:  a Ps. 38.3 billion decrease in product purchases;  a Ps. 5.8 billion decrease in extraction and exploration duties due to the elimination of these duties starting in 2025;  a Ps. 21.9 billion decrease in fixed asset impairment, resulting from a lower discount rate applied; partially offset by  a Ps. 5.8 billion increase in exploration expenses and unsuccessful wells;  a Ps. 5.4 billion increase in conservation and maintenance expenses;  a Ps. 3.3 billion increase in taxes on domestic sales;  a Ps. 7.1 billion increase in other operating expenses;  a Ps. 3.2 billion increase in auxiliary services paid to third parties. Taxes and Duties During 3Q25, total taxes and duties amounted to Ps. 47.7 billion, including the Oil Welfare Duty, compared to a credit of Ps. 6.0 billion in the same period of 2024. This increase was mainly due to the application of the tax incentive established by the decree dated August 23, 2024, which granted a 100% tax credit on the provisional payments of the Profit-sharing Duty corresponding to the months of May, June, and July 2024. As a result, the tax expense for the quarter showed a significant increase. Net Income Evolution (Loss) In the third quarter of 2025, PEMEX recorded a net loss of Ps. 61.2 billion, compared to a net loss of Ps. 161.5 billion in 3Q24.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 30 of 128 The main factors contributing to this variation were: i) a decrease in cost of sales; ii) a decrease in fixed asset impairment; iii) an increase in foreign exchange gains; partially offset by iv) a decline in sales; v) an increase in financial asset impairment; vi) higher costs associated with derivative financial instruments; and vii) an increase in taxes and duties. During the quarter, a foreign exchange gain of Ps. 33.4 billion was recorded, compared to a foreign exchange loss of Ps. 130.1 billion in 3Q24. This variation was driven by the appreciation of the Mexican peso against the U.S. dollar in 3Q25, in contrast to the depreciation observed during the same period of the previous year. The exchange rate moved from Ps. 18.8928 per U.S. $ 1.00 on June 30, 2025, to Ps. 18.3825 per U.S. $ 1.00 on September 30, 2025, representing a 2.7% change. Additionally, the cost of Ps. 2.8 billion was recorded for derivative financial instruments in 3Q25, compared to a profit of Ps. 2.5 billion in 3Q24. This change is mainly explained by the fair value effect of cross-currency swaps, currency options, and crude oil options. Comprehensive Income (Loss) In 3Q25, comprehensive income totaled Ps. 175.8 billion, primarily driven by actuarial losses resulting from a decrease in the discount rate from 10.30% as of June 30, 2025, to 9.75% as of September 30, 2025, and negative foreign currency translation effects totaling Ps. 13.7 billion, associated with the depreciation of the U.S. dollar against the Mexican peso. Consolidated Balance Sheet as of September 30, 2025 Working Capital As of September 30, 2025, a negative working capital of Ps. 463.8 billion was recorded, compared to a negative working capital of Ps. 768.0 billion as of December 31, 2024. This positive variation of Ps. 304.2 billion was mainly driven by:  an increase in cash and cash equivalents of Ps. 306.2 billion;  an increase in Federal Government Bonds of Ps. 6.7 billion;  an increase in assets from derivative financial instruments of Ps. 7.0 billion;  an increase in inventories of Ps. 3.7 billion;  a decrease in liabilities from derivative financial instruments of Ps. 34.6 billion; partially offset by  an increase in short-term debt of Ps. 17.9 billion;  an increase in suppliers of Ps. 11.1 billion;  a decrease in other accounts receivable of Ps. 9.9 billion;  a decrease in accounts receivable of Ps. 8.2 billion; and  an increase in accrued expenses and lease liabilities of Ps. 8.3 billion. Debt Financial Resources As of September 30, 2025, Petróleos Mexicanos, the State-Owned Company, together with its subsidiary entities, carried out financing activities—including short-term bank borrowings—amounting to Ps. 817.3 billion (U.S. $ 44.5 billion). Total amortizations during the period amounted to Ps. 795.9 billion (U.S. $ 43.3 billion). As of that date, 92.1% of the total debt was denominated in currencies other than the Mexican peso, primarily in U.S. dollars. For accounting purposes, this debt is translated into Mexican pesos using the closing exchange rate.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 31 of 128 Financing Activities In line with the Business Plan of Petróleos Mexicanos, State-Owned Productive Enterprise, and its Subsidiary Companies for 2023– 2027, the strategy to converge toward zero net debt continues. Financial Market Operations In the third quarter of 2025, PEMEX carried out following financing operations. Date Instrument Amount (Billion) Due date August 18, 2025 Contract U.S. $ 11.3 August, 2030 Revolving Credit Facilities PEMEX maintains revolving credit facilities for liquidity management totaling U.S. $ 5.7 billion and Ps. 20.5 billion. As of September 30, 2025, U.S. $ 4.2 billion and Ps. 20.5 billion were available. Hedging Strategy Since 2017, PEMEX has implemented an annual hedging strategy to protect its revenues against market volatility. Crude Oil For fiscal year 2025, the oil hedging strategy covers approximately 38% of the company’s estimated total exposure. This strategy is based on monthly put-spread purchases, designed to provide protection against price drops of up to U.S. $ 5 per barrel for the Mexican crude oil mix. The strike price is selected based on a balance between cost and protection, as determined by PEMEX. As a result of crude oil price volatility observed through September 2025, PEMEX obtained a gain of U.S. $ 157.6 million. Crack Spread Hedding To mitigate the impact of potential declines in gasoline and diesel crack spreads, PEMEX implemented a hedging strategy in 2025 to safeguard its cash flows. As of the end of June, the strategy covered 5.31 million barrels of gasoline and 0.99 million barrels of diesel for the periods from March to August and July to October 2025, respectively. As a result of gasoline crack spread volatility between January and September 2025, the gasoline hedge yielded a net gain of U.S. $ 4.12 million. Foreign Exchange Hedging To strengthen its financial position, PEMEX executed a bond buyback, which involved unwinding derivative positions associated with foreign exchange hedging instruments, with a notional amount of EUR 500 million. As a result, a net gain of U.S. $ 53.7 million was recorded as of September 30, 2025.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 33 of 128 Strategic pillars and key goals 1. Liquid hydrocarbon production  PEMEX will contribute 92–95% of national production (approximately 1.8 million bpd).  Reactivation of mature fields and development of projects such as Zama and Trion.  Estimated reserves: 3,000 MMb of liquids and 13,671 MMcf of gas. 2. Gas production  Increase to 4,713 MMcfd between 2026–2030, with a peak of 5,010 MMcfd in 2028.  Development of projects in Lakach and other conventional and frontier areas with high potential. 3. Refining and petrochemicals  Enhance reliability and performance of the National Refining System, with key projects including capacity increases at Tula, Minatitlán, Madero, and Salina Cruz.  Rehabilitation of ammonia plants and optimization of the ethane–ethylene value chain. 4. Logistics and new businesses  Provision of logistics services to third parties.  Electricity sales to the Federal Electricity Commission (CFE) through four cogeneration plants: Tula, Salina Cruz, Cangrejera, and Nuevo PEMEX.  Development of pipeline infrastructure projects: Interoceanic, Conexión Maya, and Coatzacoalcos II. 5. Energy innovation and sustainable production  Development of renewable and residual energy projects (solar, wind, geothermal).  Natural hydrogen production and lithium extraction.  Production of biojet fuel. 6. Sustainability and social commitment  2030 environmental goals: reduction of greenhouse gases, methane, and sulfur dioxide emissions; soil remediation; and doubling of water reuse.  Strengthening the safety, occupational health, and environmental protection system, with emphasis on risk prevention and the well-being of employees and nearby communities.  Promotion of territorial well-being through health services, educational infrastructure, and support for local governments, aligned with the UN Sustainable Development Goals (SDGs) in PEMEX’s areas of operation.  Disclosure of climate-related risks and opportunities in line with international standards. PEMEX capitalization and financing strategy[7] The Comprehensive Capitalization and Financing Strategy aims to ensure that PEMEX has the resources required to operate efficiently, maintain the stability of its supply chain, and reduce its reliance on short-term financing. The support of the Federal Government, through financial mechanisms coordinated by the Ministry of Finance and Public Credit (SHCP) and the Ministry of Energy (SENER), is essential to achieving these objectives. The strategy includes capital injections, debt refinancing, financial discipline, sustainability, and innovative instruments such as financial vehicles to address investment needs and supplier payments. It also prioritizes high-value, low-risk projects, integrating environmental and community criteria. Internally, financial operations and governance are being strengthened through adjustments designed to improve revenues, reduce costs, and ensure responsible resource management, thereby preventing elevated leverage levels in the future.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 34 of 128 This strategy is structured around five fundamental pillars: 1. Management of financial and commercial debt: Focused on reducing leverage, improving the maturity profile, and optimizing financial costs through innovative instruments such as Pre-Capitalized Notes (P-Caps), long-term refinancing, and the regularization of payables to suppliers. 2. Optimization of financial operations: Implementation of budgetary controls, rigorous project evaluation criteria, risk management strategies, and divestment of non-profitable assets to enhance operational efficiency and cash generation. 3. Investment financing: Prioritization of high-return, low-risk projects, supported by financial vehicles that enable the allocation of up to Ps. 250 billion without exerting pressure on the debt ceiling or compromising fiscal stability. 4. Good governance in financial processes: Strengthening governance through budgetary discipline, internal controls, transparency, and accountability, in alignment with the company’s strategic objectives. 5. Sustainable financing framework and ESG criteria: Promotion of projects aligned with environmental, social, and governance (ESG) principles, supporting energy transition and sustainable operations. PEMEX strengthens its capabilities through Mixed Development Assignments PEMEX is promoting Mixed Development Assignments with the objective of complementing its financial, operational, technical, and technological capabilities. In line with the Hydrocarbons Sector Law, the company has selected 11 projects under this model and is evaluating 10 additional opportunities. Among the fields under consideration are Tamaulipas Constituciones, Cuervito, Agua Fría, Tupilco Terciario, and Nobilis-Maximino, among others. Work and Services Contracts Developed and Financed by Third Parties – Ixachi Field PEMEX implemented the Work and Services Contracts Developed and Financed by Third Parties (COSDFT) scheme to incorporate production through private investment while retaining ownership of the assignments and technical responsibility for the projects. On September 29, the first COSDFT contract was signed for the drilling of up to 32 wells in the Ixachi field, as well as for the construction of discharge lines and the expansion of two macro-locations over a three-year period. PEMEX and STPRM Sign Wage Review Agreement PEMEX and the Mexican Petroleum Workers Union (STPRM) concluded the 2025–2027 wage review, agreeing to a 4.5% salary increase and a 2.5% increase in benefits, both effective retroactively as of August 1, 2025. FORWARD-LOOKING STATEMENT AND CAUTIONARY NOTE Variations Cumulative and quarterly variations are calculated comparing the period with the same one of the previous year, unless specified otherwise. Rounding Numbers may not total due to rounding. Financial Information Excluding budgetary and volumetric information, the financial information included in this report and the annexes hereto is based on unaudited consolidated financial statements prepared in accordance with International Financial Reporting Standards as issued

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 35 of 128 by the International Accounting Standards Board (“IFRS”), which PEMEX has adopted effective January 1, 2012. For more information regarding the transition to IFRS, see Note 23 to the consolidated financial statements included in Petróleos Mexicanos’ 2012 Form 20-F filed with the Securities and Exchange Commission (SEC) and its Annual Report filed with the Comisión Nacional Bancaria y de Valores (CNBV). EBITDA is a non-IFRS measure. We show a reconciliation of EBITDA to net income in Table 33 of the annexes to this report. Budgetary information is based on standards from Mexican governmental accounting; therefore, it does not include information from the subsidiary companies or affiliates of Petróleos Mexicanos. It is important to mention that 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. Methodology We might change the methodology of the information disclosed to enhance its quality and usefulness, and/or to comply with international standards and best practices. Foreign Exchange Conversions Convenience translations into U.S. dollars of amounts in Mexican pesos have been made at the exchange rate at close for the corresponding period, unless otherwise noted. Due to market volatility, the difference between the average exchange rate, the exchange rate at close and the spot exchange rate, or any other exchange rate used could be material. Such translations should not be construed as a representation that the Mexican peso amounts have been or could be converted into U.S. dollars at the foregoing or any other rate. It is important to note that we maintain our consolidated financial statements and accounting records in pesos. As of September 30, 2025, the exchange rate of Ps. 18.3825 = U.S. $ 1.00 is used. Fiscal Regime As of January 1, 2015, the fiscal regime applicable to Petróleos Mexicanos is established under the Hydrocarbons Revenue Law.On March 18, 2025, the new secondary regulatory framework was published in the Federal Official Gazette. The Hydrocarbons Revenue Law was amended and several articles were repealed, modifying PEMEX’s fiscal regime. The Profit-Sharing Duty, the Hydrocarbon Extraction Duty, and the Hydrocarbon Exploration Duty were repealed and replaced with the “Welfare Oil Duty” (Derecho Petrolero para el Bienestar). This new duty establishes a single rate applicable to the value of hydrocarbons extracted by assignees, thereby simplifying the fiscal framework. It sets a unified rate of 30% on the value of extracted hydrocarbons, without allowing deductions, and a differentiated rate of 11.63% for non-associated gas. In addition, the reform exempts PEMEX from paying Income Tax (ISR) due to its change in legal status to a State-Owned Public Company. The Special Tax on Production and Services (IEPS) applicable to automotive gasoline and diesel is established under the Special Tax on Production and Services Law. PEMEX acts as an intermediary between the Ministry of Finance and Public Credit (SHCP) and the final consumer by collecting the IEPS and subsequently transferring it to the Federal Government. As of January 1, 2018, gasoline and diesel retail prices are determined under market conditions. Production-sharing In accordance with Production-sharing Agreements signed by Petróleos Mexicanos, due to its participation in bidding rounds organized by the National Hydrocarbons Commission (CNH), in addition to the migration of blocks, Petróleos Mexicanos will disclose only its share of production for blocks Ek-Balam, Block 2 Tampico-Misantla (Round 2.1), Block 8 Southeastern Basins (Round 2.1), Santuario, Misión, Block 16 Tampico-Misantla-Veracruz (Round 3.1), Block 17 Tampico-Misantla-Veracruz (Round 3.1), Block 18 Tampico-Misantla-Veracruz (Round 3.1), Block 29 Southeastern Offshore Basins (Round 3.1), Block 32 Southeastern Basins Marino (Round 3.1), Block 33 Southeastern Offshore Basins (Round 3.1) y Block 35 Southeastern Offshore Basins (Round 3.1).

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 36 of 128 Hydrocarbon Reserves In accordance with the Hydrocarbons Sector Law, published in the Official Gazette of the Federation on March 18, 2025, the Ministry of Energy (SENER) will establish and manage the National Hydrocarbons Information Center, comprised by a system to obtain, safeguard, manage, use, analyze, keep updated and publish information and statistics related; which includes estimations, valuation studies and certifications. On August 13, 2015, the CNH published the Guidelines regulating the procedure for quantifying and certifying the Nation's reserves and the report on related contingent resources. As of January 1, 2010, the Securities and Exchange Commission (SEC) changed its rules to permit oil and gas companies, in their filings with the SEC, to disclose not only proved reserves, but also probable reserves and possible reserves. Nevertheless, any description of probable or possible reserves included herein may not meet the recoverability thresholds established by the SEC in its definitions.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 62 of 128 [800007] Annex - Financial derivate instruments Management discussion about the policy uses of financial derivate instruments, explaining if these policies are allowed just for coverage or for other uses like trading [text block] 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 over financial risk exposure, financial risk mitigation schemes, DFIs trading of Petróleos Mexicanos and the subsidiary entities 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 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 minimize 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, both at a global and 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 the company’s Industrial Processes segment (formerly Pemex Industrial Transformation) 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.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 63 of 128 Most of 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. General description about valuation techniques, standing out the instruments valuated at cost or fair value, just like methods and valuation techniques [text block] Fair Value of DFIs 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. 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.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 64 of 128 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. 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 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. 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. When available, PEMEX measures fair value using Level 1 inputs, because they generally provide the most reliable evidence of fair value. PEMEX’s DFIs’ fair-value assumptions and inputs fall under Level 2 of the fair value hierarchy for market participant assumptions. Management discussion about intern and extern sources of liquidity that could be used for attending requirements related to financial derivate instruments [text block] 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, PEMEX has acquired committed revolving credit lines in order to mitigate liquidity risk. During the third quarter of 2025 PEMEX did not enter into FX Forwards MXN/USD in order to preserve an adequate level of liquidity in U.S. dollars. During the third quarter of 2025, none DFIs entered into with this purpose expired. As of the third quarter of 2025, in order to mitigate liquidity risk, PEMEX carried out two voluntary synthetic recouponings which involved the restructuring of five UDI-MXN DFIs. In addition, during 2024 PEMEX entered into an MXN-USD prepaid swap maturing in 2026 and carried out a voluntary synthetic recouponing which involved the restructuring of five UDI-MXN DFIs.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 65 of 128 For the same purpose, during 2023, PEMEX entered into two MXN/USD prepaid swaps maturing in 2025 and in 2026, respectively. The first of these matured during the second quarter of 2025. 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. Certain PMI companies mitigate their liquidity risk through several mechanisms, the most important of which is the Centralized Treasury. In addition, PMI companies have access to bilateral credit lines through this structure. 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 and management explanation in principal risk exposures identified, as contingencies and events known by the administration that could affect future reports [text block] Market Risk (i)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) and to Mexican peso Interbank Interest rate (TIIE). 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 the third quarter of 2025, none interest rate DFI matured. Similarly, in order to eliminate the volatility associated with variable interest rates of long-term financing operations, PMI NASA has also executed interest rate swap agreements denominated in U.S. dollars. During the third quarter of 2025 there were 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.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 66 of 128 TIIE reference rates transition 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, Petroleos Mexicanos will carry out the actions it deems pertinent and necessary to modify contracts referenced to TIIE rates in 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 As of September 30, 2025 (in thousands of each currency) Deuda TIIE 28D MXN 96,752,356 IFD TIIE 28D MXN 31,733,673 *Note: Notional amounts with maturity after September 30, 2025. PEMEX’s portfolio also consists of additional debt instruments and DFIs referenced at fixed rates, which are not listed in the tables above since PEMEX’s fixed rate portfolio will not be impacted by this change. (ii)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.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 67 of 128 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. The underlying currencies of PEMEX’s DFIs are the euro, Japanese yen and pounds sterling against the U.S. dollar and UDIs against the peso. No DFIs used for exchange rate risk hedging matured during the third quarter of 2025. During the third quarter of 2025, as a result of Pemex's liability management, four unwinds of exchange rate risk hedging DFIs associated with the repurchased bonds were carried out for a cumulative notional amount of €500 million. 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. PMI Trading believes it can adequately manage the risk created by the payment of taxes in domestic currency without the need to enter into hedging instruments because the exposure to this risk is marginal relative to the total flows of U.S. dollar. In addition, in the event that a potential foreign exchange risk arises in connection with a commercial transaction, PMI Trading may implement risk mitigation measures by entering into DFIs. (iii)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 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.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 68 of 128 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 four 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. During the third quarter of 2025, none DFIs entered into with the purpose of mitigating hydrocarbon price risk expired. Additionally, PEMEX cash flows are exposed to crack spread movements as these determine the refining margin. During the third quarter of 2025, PEMEX continued to implement 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 3,510,000 barrels for the period between July and November 2025. During the third quarter of 2025, five DFIs entered into with this purpose expired. 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 1,530,000 barrels for the period between May and August 2025. During the third quarter of 2025, seventeen DFIs entered into with this purpose expired. In addition to supplying natural gas, the company’s Industrial Processes segment (formerly Pemex Industrial Transformation) 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. Since 2017, when this service is offered, the company’s Industrial Processes segment (formerly Pemex Industrial Transformation) must enter into DFIs with Petróleos Mexicanos under the opposite position to those DFIs offered to its customers in order to mitigate the market risk it would bear under such offered DFIs. Petróleos Mexicanos then transfers the related price risk derived from the DFI position held with the company’s Industrial Processes segment (formerly Pemex Industrial Transformation) to financial counterparties by entering into the opposite position DFIs with such parties. As of the third quarter of 2025, there were no DFIs since all the DFIs in its portfolios expired in 2019. In case of entering into new trades, the company’s Industrial Processes segment (formerly Pemex Industrial Transformation) DFI portfolios have VaR and CaR limits in order to limit market risk exposure. 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. During the third quarter of 2025, PMI Trading closed sixteen DFIs positions listed in CME-Clearport related to commodities, with a profit (loss) of Ps. (179,947) recognized under the concept of (Loss) Return in DFIs. During the third quarter of 2025, PMI Trading had thirty-nine margin calls, which accounted for a positive net flow of Ps. 12,748.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 69 of 128 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 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 with “recouponing” provisions (pursuant to which when the MtM exceeds the threshold specified in the recouponing clause, the MtM is adjusted to cero 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 During the third quarter of 2025, none of the specified thresholds were reached. 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. There were no defaults during the third quarter of 2025. 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. Furthermore, by means of its credit guidelines for DFI operations, the company’s Industrial Processes segment (formerly Pemex Industrial Transformation) significantly reduces its credit risk exposure related to the DFIs. In order to qualify for these DFIs, customers of the company’s Industrial Processes segment (formerly Pemex Industrial Transformation) 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 the company’s Industrial Processes segment (formerly Pemex Industrial Transformation) 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.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 70 of 128 As of the third quarter of 2025, the company’s Industrial Processes segment (formerly Pemex Industrial Transformation) had no DFIs since all the DFIs of its portfolios expired in 2019. As such, once the total settlement of the operations was carried out, the exempt credit lines expired, and the guarantees deposited by the clients were entirely returned. 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. SENSITIVITY ANALISIS PEMEX has entered into DFIs with the purpose to mitigate the market risk for specific flows or predetermined volumes associated with its operations. PEMEX’s DFIs have the same characteristics (e.g. underlying assets, payment dates, amounts, volumes) as the hedged position, but with the opposite exposure to the market risk factors. As a result of these mitigation strategies, PEMEX has a minor sensitivity to the hedged market risk factors. 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. Natural gas DFIs that the company’s Industrial Processes segment (formerly Pemex Industrial Transformation) has offered to its 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 the third quarter of 2025, the company’s Industrial Processes segment (formerly Pemex Industrial Transformation) did not have any DFI to report, since all the DFIs of its portfolios expired in 2019. As such, it is no 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 Value at Risk (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. Quantitative information for disclosure [text block] QUANTITATIVE DISCLOSURE Accounting treatment applied and the impact in the financial statements 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 (cost) income, net” line item in the consolidated statement of comprehensive income.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 71 of 128 As of September 30, 2025, and December 31, 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. (58,130,722) and Ps. (99,768,509), respectively. As of September 30, 2025, and December 31, 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 (cost) income, net” line item in the consolidated statement of comprehensive income. In accordance with established accounting policies, PEMEX has analysed the different contracts (financial and non-financial contracts) 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 September 30, 2025, and December 31, 2024, PEMEX did not recognize any embedded derivatives (foreign currency or index) in the financial and non-financial contracts. For the nine-months periods ended September 30, 2025, and 2024, PEMEX recognized a net gain (loss) of Ps. 18,106,809 and Ps. (13,283,553), respectively, in the “Derivative financial instruments (cost) income, net” line item with respect to DFIs treated as instruments entered into for trading purposes.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 81 of 128 [813000] Notes - Interim financial reporting Disclosure of interim financial reporting [text block] NOTE 1. STRUCTURE AND BUSINESS OPERATIONS OF PETRÓLEOS MEXICANOS STATED-OWNED PUBLIC COMPANY AND SUBSIDIARY COMPANIES Petróleos Mexicanos was created by a decree issued by the Mexican Congress on June 7, 1938. The decree was published in the Diario Oficial de la Federación (“Official Gazette of the Federation”) on July 20, 1938 and came into effect on that date. On December 20, 2013, the Decreto por el que se reforman y adicionan diversas disposiciones de la Constitución Política de los Estados Unidos Mexicanos, en Materia de Energía (Decree that amends and supplements various provisions of the Mexican Constitution relating to energy matters), was published in the Official Gazette of the Federation. This Decree came into effect on December 21, 2013 and includes transitional articles setting forth the general framework and timeline for implementing legislation relating to the energy sector. 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 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,

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 82 of 128 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: • 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; • 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 • 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 Organic Statute, previously approved by the Board of Directors of Petróleos Mexicanos, was published in the Federal Official Gazette. 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. AUTHORIZATION AND BASIS OF PREPARATION Authorization On October 27, 2025, these condensed consolidated interim 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.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 83 of 128 Basis of preparation A. Statement of compliance PEMEX prepared its condensed consolidated interim financial statements as of September 30, 2025 and December 31, 2024, and for the three- and nine-month periods ended September 30, 2025 and 2024, in accordance with IAS 34, “Interim Financial Reporting” (“IAS 34”) of the IFRS Accounting Standards (“IFRS”), as issued by the International Accounting Standards Board. These condensed consolidated interim financial statements do not include all the information and disclosures required for full annual consolidated financial statements and should be read in conjunction with PEMEX’s audited consolidated financial statements as of and for the year ended December 31, 2024. PEMEX estimates that there is no significant impact on its condensed consolidated interim financial statements due to the seasonality of operations. These condensed consolidated interim financial statements follow the same accounting policies and methods of computation as PEMEX’s audited consolidated financial statements as of and for the year ended December 31, 2024. B. Basis of accounting These condensed consolidated interim 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. Going concern The condensed consolidated interim 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 17-F). D. Functional and reporting currency These condensed consolidated interim financial statements are presented in Mexican pesos, which is both PEMEX’s functional currency and reporting currency, due to the following: i. The economic environment in which PEMEX operates is Mexico, where the legal currency is the Mexican peso; ii. The budget through which Petróleos Mexicanos operates as an entity of the Mexican Government, including the ceiling for personnel services, is elaborated, approved and exercised in Mexican pesos; iii. Employee benefits provision was 34% and 29% of PEMEX’s total liabilities as of September 30, 2025 and December 31, 2024, respectively. This provision is computed, denominated and payable in Mexican pesos; and iv. Cash flows for payment of general expenses, taxes and duties are realized in Mexican pesos.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 84 of 128 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 condensed consolidated interim 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. Use of judgments and estimates The preparation of the condensed consolidated interim 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 condensed consolidated interim financial statements, as well as the recorded amounts of income, costs and expenses during the period. Actual results may differ from these estimates. Significant estimates and underlying assumptions are reviewed, and the effects of such revisions are recognized in the periods in which any estimates are revised and in any future periods affected by such revision. The significant judgements made by management in applying PEMEX’s accounting policies and the key sources of estimation uncertainty were the same as those described in PEMEX’s audited consolidated financial statements as of and for the year ended December 31, 2024. i.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: • Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities. • 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).

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 85 of 128 • 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. PEMEX recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred. NOTE 3. MATERIAL ACCOUNTING POLICIES The accounting policies applied in the preparation of these condensed consolidated interim financial statements are consistent with those applied in the preparation of PEMEX’s annual consolidated financial statements as of and for the year ended December 31, 2024, except for the adoption of new standards effective as of January 1, 2025. However, these new standards have not had a material effect on the condensed consolidated interim financial statements of PEMEX. NOTE 4. NEW ACCOUNTING STANDARDS AND RECENTLY ISSUED ACCOUNTING STANDARDS New Accounting Standards A number of new standards are effective for annual periods beginning after January 1, 2025 and earlier application is permitted; however, PEMEX has not early adopted the new or amended standards in preparing these condensed consolidated interim financial statements. The following amended standards and interpretations are not expected to have a significant impact on PEMEX’s condensed consolidated interim financial statements: Recently Issued Accounting Standards i. Applicable as of January 1, 2025 • Lack of Exchangeability (Amendments to IAS 21) • Classification and Measurement of Financial Instruments (Amendments to IFRS 9 and IFRS 7) • Subsidiaries without Public Accountability Disclosures (IFRS 19) ii.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 87 of 128 NOTE 6. SEGMENT FINANCIAL INFORMATION PEMEX’s primary business is the exploration and production of crude oil and natural gas, as well as the production, processing, marketing and distribution of petroleum and petrochemical products. As of September 30, 2024 and December 31, 2024 and PEMEX’s operations were conducted through seven business segments: • Exploration and Production; • Industrial Transformation; • Logistics; • Deer Park; • the Trading Companies; • Corporate; and • Other Operating Subsidiary Companies. Following the dissolution of the subsidiary entities on March 19, 2025 and pursuant the New Organic Statute, as of June 1, 2025, PEMEX’s operations are now conducted through six segments: • Exploration and Extraction; • Industrial Processes; • Energy Transformation; • Deer Park; • the Trading Companies; and • Other Operating Subsidiary Companies. The primary sources of revenue for PEMEX’s business segments are as described below: • 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 12 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. • 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 Eletricity 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. • 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. • The Deer Park segment includes DPRLP’s operations, generates revenues from sales of distillates and gasoline in the U.S. market.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 88 of 128 • 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, natural gas and petroleum and petrochemical products in international markets. • 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 entities and companies with industrial activities. As of March 19, 2025 this segment includes the Logistics and Corporate activities, previously reported as separate segments. • 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. • 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.

PEMEX recognizes revenue when it transfers control over a good or service to a customer. 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 Crude oil sales Export sales of crude oil are based on delivery terms established in contracts or orders. All sales are performed by the Free on Board International commercial term (“FOB” Incoterm). Crude oil sale contracts consider possible customers’ claims due to product quality, volume or delays in boarding, which are estimated in the price of the transaction. For orders that have variations in price, revenue is adjusted on the closing date of each period. The subsequent variations in the fair value at the different reporting dates are recognized according to IFRS 9. Revenue is recognized at a point in time when control of the crude oil has transferred to the customer, which occurs when the product is delivered at the point of shipping. Invoices are generated at that time and are mostly payable within the deadlines established in contracts or orders. Payments in respect of crude oil sold and delivered shall be made within 30 days after the date of the bill of lading therefor. For international market crude oil sales, revenue is recognized with a provisional price, which undergoes subsequent

There may be a period of up to two months in determining the final sale price, such as in the case of sales to some regions. Revenue is measured initially estimating variables such as quality and volume claims, delays in boarding, etc. 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. 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. Revenue is initially measured by estimating variables such as quality and volume claims, etc. Invoices are usually payable within 30 days. Sales of natural gas There is only one performance obligation that includes transport and handling services to the point of delivery. 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. 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, Income is recognized over time as the service is rendered. Invoices are usually payable within 22 days.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 98 of 128 Products / services Nature, performance obligations Timing of revenue recognition depending on the term of the service. 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. Other products There is only one performance obligation that includes transportation for delivery to destination. 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. 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. Invoices are usually payable within 30 days. B. Accounts receivable in the statement of financial position As of September 30, 2025 and December 31, 2024, PEMEX had accounts receivable derived from customer contracts in the amounts of Ps. 118,557,988 and Ps. 126,733,175, respectively (see Note 10). C. Practical expedients i. 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. Practical expedient PEMEX applied the practical expedient, so disclosure about remaining performance obligations that conclude in less than one year is not needed.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 99 of 128 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.

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. B. 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 liabilities.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 101 of 128 When available, PEMEX measures fair value using Level 1 inputs, because they generally provide the most reliable evidence of fair value. C. Fair value of DFIs 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. 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 DFIs’ fair-value assumptions and inputs fall under Level 2 of the fair value hierarchy for market participant assumptions. D. Accounting treatment applied and impact in the financial statements 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 condensed consolidated interim financial statements as

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 102 of 128 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 (cost) income, net” line item in the condensed consolidated interim statement of comprehensive income. As of September 30, 2025, and December 31, 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 condensed consolidated interim statement of financial position, was Ps. (58,130,722) and Ps. (99,768,509), respectively. As of September 30, 2025, and December 31, 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 (cost) income, net” line item in the condensed consolidated interim statement of comprehensive income. In accordance with established accounting policies, PEMEX has analyzed the different contracts (financial and non-financial contracts) 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 September 30, 2025, and December 31, 2024, PEMEX did not recognize any embedded derivatives (foreign currency or index) in the financial and non-financial contracts. For the nine-month periods ended September 30, 2025, and 2024, PEMEX recognized a net gain (loss) of Ps.18,106,809 and Ps. (13,283,533), respectively, in the “Derivative financial instruments (cost) income, net” line item with respect to DFIs treated as instruments entered into for trading purposes. E. TIIE reference rates transition Banco de Mexico (the Mexican Central Bank) announced that the 28-day linked to Interbank Interest rate (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 references reference rates for new contracts as of January 1, 2024. Petróleos Mexicanos will carry out the actions it deems pertinent and necessary to modify contracts referenced to TIIE rates in 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 Amounts As of September 30,2025 (in thousands of Pesos) Debt TIIE 28D MXN 96,752,356 DFI TIIE 28D MXN 31,733,673 *Note: Notional amounts with maturity after September 30, 2025. PEMEX’s portfolio also consists of additional debt instruments and DFIs referenced at fixed rates, which are not listed in the table above since PEMEX’s fixed rate portfolio will not be impacted by this change.

(32,390,160) Ps. 15,447,401 As of September 30, 2025, the Exploration and Extraction segment recognized a net impairment of Ps. (32,390,160) mainly due to: (i) a negative effect in crude oil prices of Ps. 43,048,812, mainly in the Cantarell, Burgos, Tsimin Xux, Antonio J. Bermúdez, CGUs; (ii) an increase in production costs generating a negative effect of Ps. 27,390,272, mainly in the Tsimin Xux, Ogarrio Sanchez Magallanes, and Cantarell CGUs; and (iii) a negative effect of Ps. 11,836,310 due to the fluctuations of the exchange rate from Ps. 20.2683 = U.S.$1.00 as of December 31, 2024 to Ps. 18.3825 = U.S.$1.00 as of September 30, 2025. These effects were partially offset by (i) a decrease in the discount rate of Ps. 41,236,392 from 10.86% as of December 31, 2024 to 7.96% as of September 30, 2025; (ii) a positive tax effect of Ps. 5,455,293 due to a lower tax base due to the decrease in prices and production costs; and (iii) an increase in production profiles volume in the barrel of crude oil equivalent generating a positive effect of Ps. 3,193,549. As of September 30, 2024, Pemex Exploration and Production recognized a net reversal of impairment of Ps.15,447,401 mainly due to: (i) an increase in crude oil gas and condensates prices, generating a positive effect of Ps. 41,135,676 mainly in the Cantarell, Aceite Terciario del Golfo and Tamaulipas Constituciones CGUs; (ii) a positive effect of Ps.31,371,838, due to the fluctuations of the exchange rate from Ps.16.9220 = U.S.$1.00 as of December 31, 2023, to Ps.19.6290 = U.S.$1.00 as of September 30, 2024; and (iii) a positive effect of the decrease in expenses of Ps.28,543,448 due to changes in operational strategies in Cantarell, Aceite Terciario del Golfo, Tamaulipas Constituciones and Lakach CGUs. These effects were partially offset by (i) a negative effect in the discount rate of Ps.44,734,671, from 9.93% in December 31, 2023 to 10.28% in September 30, 2024; (ii) a negative effect of the decrease in production profiles of Ps.27,335,248 in the Tsimin Xux, Ogarrio – Sánchez Magallanes, Antonio J. Bermudez and Burgos CGUs; and (iii) a negative tax effect of Ps.13,533,642 due to an increased tax base resulting from higher prices of petroleum products.

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 108 of 128 The CGUs of the Exploration and Extraction segment 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. The Exploration and Extraction segment determines the recoverable amount of fixed assets based on the long-term estimated prices for Pemex’s proved reserves. The recoverable amount on each asset is the value in use. 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: 2025 2024 Average crude oil price 60.59 U.S.$/bl 65.47 U.S.$/bl Average gas price 4.67 U.S.$/mpc 4.80 U.S.$/mpc Average condensates price 66.19 U.S.$/bl 73.18 U.S.$/bl After-tax discount rate 7.96% annual 10.28% annual For the nine-month periods ended September 30, 2025 and 2024 the total forecast production, calculated with a horizon of 25 years, was 6,371 Million barrels of oil equivalent (Mboe) and 6,566 Mboe, respectively. The Exploration and Extraction segment, 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.

B. Mexican Government contributions As of September 30, 2025 and December 31, 2024, there were no Mexican Government contributions apart from Certificates of Contribution “A”. C. Legal reserve Under Mexican law, each of the Subsidiary Companies is required to allocate a certain percentage of its net income to a legal reserve fund until the fund reaches an amount equal to a certain percentage of each Subsidiary Company’s capital stock. As of September 30, 2025 and December 31, 2024, there were no changes to the legal reserve. D. Accumulated other comprehensive income (loss) As a result of the analysis of the discount rate related to the liability for employee benefits for the nine-month period ended September 30, 2025, PEMEX recognized a net actuarial (loss) of Ps.(196,420,638) in other comprehensive income, related to retirement and post-employment benefit obligations. The variation related to retirement and post-employment benefits resulted

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 123 of 128 from a decrease in the discount rate and plan asset rates from 11.28% as of December 31, 2024, to 9.75% as of September 30, 2025. For the nine-month period ended September 30,2024, PEMEX recognized net actuarial gains of Ps.121,077,944 in other comprehensive results, net of deferred income tax of Ps. (8,039,019) related to retirement and post-employment benefits. The gains resulted from an increase in discount and plan asset return rates, rising from 9.42% on December 31, 2023 to 10.11% on September 30, 2024. E. Accumulated deficit from prior years PEMEX has recorded losses in the past several years. However, the Ley de Concursos Mercantiles (“Commercial Bankruptcy Law of Mexico”) is not applicable to Petróleos Mexicanos State-Owend Public Company and the Subsidiary Entities. 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. Uncertainty related to going concern The condensed consolidated interim 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 normal course of business. However, substantial doubt about PEMEX’s ability to continue as a going concern exists. Facts and conditions PEMEX has substantial debt, incurred mainly to finance the capital expenditures needed to carry out its capital investment projects and to fund its operating expenses. Due to its heavy fiscal burden resulting from the payment of hydrocarbon extraction duties, the cash flows derived from PEMEX’s operations in recent years have not been sufficient to fully fund its operations and capital expenditure programs, which have been partially supported by the Mexican Government's equity contributions. In addition, PEMEX´s working capital has deteriorated in recent years. In 2024, certain ratings agencies downgraded PEMEX’s credit rating, mainly driven by concerns around its operating performance, liquidity and the Mexican Government’s ability and willingness to provide PEMEX with additional liquidity, as well the volatility of the crude oil prices and the downgrade of the Mexican Government’s sovereign debt rating, impacting 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 2025. These conditions have negatively impacted PEMEX’s financial performance and liquidity position. 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.” On August 27, 2025, Moody’s Rating upgraded PEMEX’s long-term local currency senior unsecured debt ratings for its PEMEX 12U, PEMEX 14U, PEMEX 14-2, and PEMEX 15U notes to “AAA.mx” from “AA+.mx” and affirmed its outlook to stable from negative. For the nine-month period ended September 30, 2025 and 2024, PEMEX recognized net (loss) of Ps. (45,055,006) and Ps.(430,102,758), respectively. In addition, as of September 30, 2025 and December 31, 2024, PEMEX had a negative equity of Ps.(1,895,797,662), and Ps.(1,983,775,736), respectively, mainly due to continuous net losses in prior years, and a negative working capital of Ps.463,826,251 and Ps.767,968,661, as of September 30, 2025 and December 31, 2024, respectively. 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 2025 authorized PEMEX to have a financial balance budget of Ps.248,722,000 and conduct financing activities that do not represent a net debt in terms of public debt greater than Ps.245,388,650 and other financing activities that do not represent net public debt. This financial balance does

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 124 of 128 not consider the payment of principal during 2025, which PEMEX expects to cover with equity contributions from the Mexican Government. PEMEX has short-term debt principal maturities (including interest payable) of Ps.443,168,492 as of September 30, 2025. The combined effect of the above-mentioned events indicates substantial 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 2023 and 2024, and remains in effect through 2025. 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. Pursuant to the Energy Reform Decree, Petróleos Mexicanos and its Subsidiary Entities are no longer subject to income tax as of November 1, 2024. Separately, 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 Profit-Sharing Duty, the Hydrocarbon Extraction Duty and the Hydrocarbon Exploration Duty payable by Petróleos Mexicanos into the Welfare Oil Duty, which is set at a general rate of 30% on oil and fuel production and 11.63% for non-associated gas. PEMEX is currently evaluating the economic nature of the welfare oil duty, which may result in a classification change in the Statement of Comprehensive Income in subsequent periods. The Mexican Government’s Federal Budget for 2025 includes Ps.136,210,300 for PEMEX to face its short-term liabilities, which will be received during 2025. Further, PEMEX has the capacity to refinance its short-term debt maturities through direct loans and revolving credit facilities. PEMEX's ability to refinance its short-term debt depends on factors beyond its control. The Revenue Law for 2025 also authorized PEMEX to incur a net additional indebtedness up to Ps.245,388,650 (Ps.143,403,700 and U.S.$5,512,700), which is considered as public debt by the Mexican Government and may be used to partially cover its financial balance in 2025. 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 along operational strategy, aim to boost production across hydrocarbons, petrochemicals and fertilizers while reducing greenhouse gas (GHG) emissions and reinforcing social responsibility; and capitalization and financing strategy, aim to strengthen PEMEX’s financial stability through capital structure optimization, debt reduction and restructuring, cost reduction and sustainable financing. Petróleos Mexicanos State-Owned Public Company 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. As a reference, PEMEX prepared its condensed consolidated interim financial statements as of September 30, 2025 and December 31, 2024 on a going concern basis. There are certain conditions that have generated material uncertainty and significant

PEMEX Consolidated Ticker: PEMEX Quarter: 3 Year: 2025 125 of 128 doubts concerning the entity’s ability to continue operating, including recurring net losses, negative working capital and negative equity. Those financial statements do not contain any adjustments that would be required if they were not prepared on a going concern basis. G. Non-controlling interest PEMEX does not currently own all of the shares of PMI CIM and COMESA, variations in income and equity from these entities are also presented in the condensed consolidated interim statements of changes in equity (deficit) as “non-controlling interest.” As of September 30, 2025 and December 31, 2024, non-controlling interest represented (losses) of Ps.(283,179) and Ps. (274,387), respectively, in PEMEX’s equity (deficit). NOTE 18. CONTINGENCIES In the ordinary course of business, PEMEX is named in a number of lawsuits of various types. PEMEX evaluates the merit of each claim and assesses the likely outcome. PEMEX has not recorded provisions related to ongoing legal proceedings 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 condensed consolidated interim financial statements. As of September 30, 2025 and December 31, 2024, PEMEX had accrued a reserve of Ps. 31,728,996 and Ps. 13,186,811, respectively, for these contingent liabilities. As of September 30, 2025, the current status of the principal lawsuits in which PEMEX is involved is as follows: • 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.

(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. On April 5, 2022, the claim was admitted which was notified on May 17, 2022. On July 4, 2022, Pemex Exploration and Production filed a response to this claim, 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 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), informing the designation of the delegates 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, Micro Smart Systems appealed the denial of the amparo. 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 before lifting a suspension issued on September 4, 2024, and before issuing its final ruling.
