Structure, business operations, subsidiary entities, and subsidiary companies [Abstract]
Structure and Business Operations of Petroleos Mexicanos, Subsidiary Entities and Subsidiary Companies	STRUCTURE AND BUSINESS OPERATIONS OF PETRÓLEOS MEXICANOS, SUBSIDIARY ENTITIES 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 “Petróleos Mexicanos Law”) was published in the Official Gazette of the Federation. The Petróleos Mexicanos Law became effective on October 7, 2014, except for certain provisions. On December 2, 2014, the Secretaría de Energía (“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 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. The Subsidiary Entities, Pemex Exploración y Producción (“Pemex Exploration and Production”), Pemex Transformación Industrial (“Pemex Industrial Transformation”) and Pemex Logística (“Pemex Logistics”) are productive state-owned subsidiaries empowered to own property and carry on business in their own name, subject to the direction and coordination of Petróleos Mexicanos (the “Subsidiary Entities”). The Subsidiary Entities and their primary purposes, are as follows: • Pemex Exploration and Production: This entity is 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 performs activities related to refining, transformation, processing, importing, exporting, trading and the sale of hydrocarbons, petroleum products, natural gas and petrochemicals, as well as commercializes, distributes and trades methane, ethane and propylene, directly or through others; and • Pemex Logistics: This entity provides 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 provides guard and management services. The principal distinction between the Subsidiary Entities and the Subsidiary Companies (as defined below) is that the Subsidiary Entities are 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. 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, the Subsidiary Entities 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.

Disclosure of basis of preparation [Abstract]
Authorization and Basis of Preparation	AUTHORIZATION AND BASIS OF PREPARATION Authorization On September 8, 2023, these condensed consolidated interim financial statements prepared under the International Financial Reporting Standards (“IFRS”) and the notes hereto were authorized for issuance by the following officers: Mr. Octavio Romero Oropeza, Chief Executive Officer, Mr. Carlos Fernando Cortez González, Acting Chief Financial Officer, Mr. José María del Olmo Blanco, Acting Deputy Director of Budgeting and Accounting, and Mr. Óscar René Orozco Piliado, Associate Managing Director of Accounting. Basis of preparation A. Statement of compliance PEMEX prepared its condensed consolidated interim financial statements as of June 30, 2023 and December 31, 2022, and for the three and six-month periods ended June 30, 2023, and 2022, in accordance with IAS 34, “Interim Financial Reporting” (“IAS 34”) of the IFRS as issued by the International Accounting Standards Board (“IASB”). 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, 2022. 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, 2022. B. Basis of accounting These condensed consolidated interim financial statements have been prepared using the historical cost basis method, with the exception of 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 18-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 and its Subsidiary Entities operate as entities of the Mexican Government, including the ceiling for personnel services, is elaborated, approved and exercised in Mexican pesos; iii. Employee benefits provision was approximately 35% and 33% of PEMEX’s total liabilities as of June 30, 2023 and December 31, 2022, 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. 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, 2022. 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). • 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.

Disclosure of operating segments [abstract]
Segment Financial Information	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 June 30, 2023 and December 31, 2022, PEMEX’s operations were conducted through seven business segments: 1. Exploration and Production; 2. Industrial Transformation; 3. Logistics; 4. Deer Park (beginning January 20, 2022); 5. Trading Companies; 6. Corporate; and 7. Other Operating Subsidiary Companies. Due to PEMEX’s structure, there are significant amounts of inter-segment sales among the reporting segments, which are made at market prices. The primary sources of revenue for PEMEX’s business segments are as described below: • The Exploration and Production segment earns revenues from domestic sales of crude oil and natural gas, and from exporting crude oil through certain of the Trading Companies (as defined below). Crude oil export sales are made through the agent subsidiary company PMI CIM, to 16 major customers in various foreign markets. Approximately half of PEMEX’s crude oil is sold to Pemex Industrial Transformation. Additionally, it receives income from drilling services, and servicing and repairing wells. • The Industrial Transformation segment 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”). This segment’s most important products are different types of gasoline and diesel. The Industrial Transformation segment also 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 Logistics segment earns 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. • Effective January 20, 2022, the Deer Park segment includes DPRLP's operations, whose operating results and performance are currently and regularly reviewed as a separate business by PEMEX's Board of Directors. DPRLP generates revenues from sales of distillates and gasoline in the U.S. market. • The Trading Companies segment, which consist of PMI CIM, PMI NASA, PMI Trading and MGAS (the “Trading Companies”), earns revenues from trading crude oil, natural gas and petroleum and petrochemical products in international markets. • The Corporate segment provides administrative, financing and consulting services to PEMEX’s subsidiary entities and companies. • The Other Operating Subsidiary Companies segment provides 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. 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.

Nature, performance obligations and timing of revenue recognition Revenue is measured based on the consideration specified in a contract with a customer. PEMEX recognizes revenue when it transfers control over a good or service to a customer. 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. The price of the product is determined based on a market components formula and the sale of crude oil. 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 adjustments until the product has arrived at the port of destination. 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”), where applicable. 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, 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, 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. Income is recognized over time as the service is rendered. Invoices are usually payable within 22 days. 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 June 30, 2023 and December 31, 2022, PEMEX had accounts receivable derived from customer contracts in the amounts of Ps. 113,476,185 and Ps. 107,117,145, 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. When PEMEX is entitled to consideration for an amount that directly corresponds to the value of the performance that PEMEX has completed, it may recognize an income from ordinary activities for the amount to which it has the right to invoice. D . The Automotive Incentive On March 4, 2022, the Mexican Government published a decree in the Official Gazette of the Federation establishing a tax incentive pursuant to which PEMEX can recover the difference between the international reference price of gasoline and the price at which the gasoline is traded in the domestic market, effective until December 31, 2024. For the six-month periods ended June 30, 2023 and 2022, this complementary incentive amounted Ps. 19,163 and Ps. 75,055,185, respectively, which is included as a separate line item in total sales in the Statement of Comprehensive Income (Loss).

Debt is recognized 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. 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 DFIs 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 such as Bloomberg, 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 discount factor; for currency and interest rate options, this is done through the Black Scholes Model, and for crude oil options, through the Levy Model for Asian options. According to IFRS 13 “Fair Value Measurement”, the mark-to-market 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. Because PEMEX’s hedges are cash flow hedges, their effectiveness is preserved regardless of the variations in the underlying assets or reference variables, thus asset flows are fully offset by liabilities flows. Therefore, it is not necessary to measure or monitor the hedges’ effectiveness. 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 financial statements as instruments entered into for trading purposes, despite the fact that their cash flows are offset by the cash flows of the positions (assets or liabilities) to which they relate. As a result, the changes in their fair value are recognized in the “Derivative financial instruments income (cost), net” line item in the consolidated statement of comprehensive income. As of June 30, 2023, and December 31, 2022, 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. (18,675,147) and Ps. (9,486,488) , respectively. As of June 30, 2023, and December 31, 2022, PEMEX did not have any DFIs designated as hedges for accounting purposes. All of PEMEX’s DFIs are treated, for accounting purposes, as instruments entered into for trading purposes, therefore any change in their fair value, caused by any act or event, impacts directly in the “Derivative financial instruments income (cost), net” line item in the consolidated statement of comprehensive income (loss). For the six-month periods ended June 30, 2023 and 2022, PEMEX recognized a net gain (loss) of Ps. 2,788,339 and Ps. (24,509,153), respectively, in the “Derivative financial instruments income (cost), net” line item with respect to DFIs treated as instruments entered into for trading purposes. In accordance with established accounting policies, PEMEX has analyzed the different 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 June 30, 2023, and December 31, 2022, PEMEX did not recognize any embedded derivatives (foreign currency or index). E. IBOR reference rates transition As a result of the decision made by the Financial Stability Board (FSB), the Interbank Offered Rates (IBORs), such as the LIBOR in dollars (over-night “O/N”, one week “1W”, two months “2M”, and twelve months “12M”) or the EURIBOR in Euros, were scheduled to be replaced by alternative reference rates based on risk-free rates (RFR) obtained from market operations. The discontinuation of the publication of these rates was originally scheduled for December 2021. Nevertheless, on November 2020, the ICE Benchmark Administration Limited (known as “ICE”) announced an extension until June 2023 for the publication of the most common LIBOR rates in dollars (over-night “O/N” one month “1M”, three months “3M”, six months “6M” and twelve months “12M”). PEMEX identified and reviewed contracts expiring after the applicable cessation dates that could be impacted by the change in the aforementioned rates and has carried out all the pertinent negotiations with its counterparties. As of the second quarter of 2023, PEMEX has a reduced number of financial instruments referenced to LIBOR floating rates in U.S. dollars with maturity and interest rate fixation after June 2023. This portfolio of financial instruments is composed of debt instruments as shown below: *Notional Amounts As of June 30, 2023 Reference Rate (in thousands of U.S. dollars) Debt LIBOR 1M USD 450,101 LIBOR 3M USD 206,370 LIBOR 6M USD 701,113 *Note: Notional amounts with maturity after June 30, 2023 It should be noted that Petróleos Mexicanos has a financial instrument denominated in euros with the EURIBOR 3M as a reference rate. Said reference will continue to be published, by agreement of the European financial authorities, so its current contract does not require any amendment. As of the second quarter of 2023, PEMEX has completed the restructuring of the DFIs that were originally referenced to LIBOR rates, leaving only RFR as its reference indexes and is working on all the relevant documentation. Additionally, PEMEX has carried out the necessary adjustments to the financing contracts and continues to monitor the evolution of the IBORs transition in the market to anticipate any negative impact that these changes could have. The cases that had not been finalized at the end of the second quarter of 2023 were being attended and registered a high degree of progress. Given the policy of not entering into new financing operations at floating rates referenced to IBOR, since 2021 and to the second quarter of 2023, PEMEX contracted financing operations in U.S. dollars at floating rates linked to the new RFR rates. Moreover, derived from the transition to the alternative RFR, PEMEX has adopted a policy of not entering into new DFIs referenced to IBOR rates. Furthermore, the discount curves that PEMEX uses to obtain the fair value of its DFIs already include in their construction instruments of the corresponding currency referenced to the new RFR. In the event that TIIE ceases to be published, the portfolio of financial instruments referenced to these floating rates is composed of debt instruments and DFIs as shown below: *Notional Amounts As of June 30, 2023 Reference Rate (in thousands of pesos) Debt TIIE 28D MXN 106,238,606 TIIE 91D MXN 29,060,976 DFI TIIE 28D MXN 32,505,574 *Note: Notional amounts with maturity after June 30, 2023. 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 the IBOR transition. Regarding PMI Trading, its credit agreements contained flexible provisions that would help smooth the transition to an alternative rate in the event that LIBOR rates ceased to be published. PMI Trading has finished the amendment process of its credit agreements. This process has enabled PMI Trading to keep using the LIBOR rates until they are ceased to be published and then continue with the new SOFR rates as benchmark rates.

Additional information about the significant investments in joint ventures and associates is presented below: Joint venture • Deer Park . On March 31, 1993, PMI NASA acquired 49.995% of the Deer Park Refinery. In its capacity as general partner of DPRLP, Shell was responsible for the operation and management of the Deer Park Refinery (installed capacity of approximately 340,000 barrels per day of crude oil). Management decisions were made jointly with respect to investment in or disposal of assets, distribution of dividends, indebtedness and equity operations. In accordance with the investment contract and the operation of the agreement, the participants had the rights to the net assets in the proportion of their participation. This joint venture was recorded under the equity method. The investment in Deer Park as of December 31, 2021 was Ps. 6,703,324, which represented PMI NASA’s 49.995% interest in Deer Park. Acquisition of the joint venture See accounting policy in Note 3-A(i) (Business combinations) and (v) (Interests in equity-accounted investees) of PEMEX’s annual consolidated financial statements as of and for the year ended December 31, 2022. In this observable transaction the value of the debt was agreed up to U.S.$1,192,000 as the fair value of the 100% of the interest in Deer Park, i.e., U.S.$596,000, equivalent to 50.005% of the interest. On January 20, 2022, PMI SUS acquired the remaining 50.005% of participation and voting interest in Deer Park through a purchase agreement with Shell. Through this operation, PEMEX indirectly acquired control over Deer Park. As a result of the acquisition, this company is now consolidated in PEMEX’s financial statements. Beginning January 20, 2022, DPRLP’s business model changed from a company that obtained revenues from services for processing crude oil to a company that buys and processes crude oil and sells gasolines and distillates. Deer Park is a limited partnership under the laws of Delaware, with operations in Deer Park, Texas. The purpose of the acquisition is to strengthen and increase the refining capacity under PEMEX’s control. PEMEX has begun shipping products to Mexico from the refinery to strengthen the fuels supply. Prior to the acquisition, the participation in Deer Park was recognized as a joint venture. As a result, the participation was recognized in PEMEX’s consolidated financial statements using the equity method. On November 3, 2021, the Board of Directors authorized PEMEX’s capitalization of HHS and HPE up to the amount received from the Fondo Nacional de Infraestructura (National Infrastructure Fund or “FONADIN”) as a non-recoverable contribution to enable HHS and HPE, in turn, to capitalize PMI NASA and PMI SUS. These capitalizations were used to meet financial commitments arising out of the acquisition of Shell’s interest in Deer Park. During January 2022, the amount received and recorded from the FONADIN totaled Ps. 23,000,000 (U.S.$1,127,285). In addition, PEMEX entered into a borrowing of Ps. 8,974,406 (U.S.$436,000) due in one year. In recognition of this transaction, PEMEX is applying the purchase method in accordance with International Financial Reporting Standard (IFRS) 3 “Business Combinations”, accounting for the transaction as a business combination achieved in stages. The acquiree company included in the identifiable assets at the date of acquisition of DPRLP are inputs (mainly Properties, Plant and Equipment and inventories), production processes and workforce. PEMEX has determined that together the acquired inputs and processes significantly contribute to the ability to generate revenue. PEMEX has concluded that the acquired set is a business. Consideration transferred PEMEX’s purchase of control of Deer Park, through the 50.005% interest owned by Shell, included the following: Cash paid to Shell Ps. 8,597,743 U.S.$ 421,396 Payment of debt to third parties 18,289,066 896,391 Payment of DPRLP’s debt to company partners 3,496,054 171,350 Total consideration paid in cash Ps. 30,382,863 U.S.$ 1,489,137 Settlement of pre-existing relationship 6,663,803 326,609 Total consideration paid in cash and settlement of pre-existing relationship Ps. 37,046,666 U.S.$ 1,815,746 The settlement of the pre-existing relationship includes the payment of 100% of PMI NASA’s Partners Loan (Ps. 1,227,383 or U.S.$60,157 with cash and Ps. 5,436,420 or U.S.$266,452 with equity) which Deer Park used for operative purposes, and which consisted of a principal of Ps. 6,630,975 (U.S.$325,000) and interest of Ps. 32,828 (U.S.$1,609). With this settlement, the account receivable registered on PMI NASA’s books was capitalized. As the book value of this item was equal to its fair value and there were no cancellation clauses, no effects were recognized in the profit or loss of the year 2022. Acquisition-related costs Acquisition-related costs for the 50.005% interest in Deer Park totaled Ps. 145,937 (U.S.$7,091) recognized in the administrative expenses line item in the profit or loss for 2022. Identifiable assets acquired and liabilities assumed. The following table summarizes the fair value of the identifiable assets acquired, including the recognized value of the PEMEX interest prior to the purchase. Cash and cash equivalents Ps. 1,597,759 U.S.$ 78,310 Inventories 6,918,473 339,091 Other current assets 131,661 6,453 Total current Assets Ps. 8,647,893 U.S.$ 423,854 Property, Plant and Equipment 29,669,961 1,454,196 Total identifiable net assets acquired Ps. 38,317,854 U.S.$ 1,878,050 PEMEX carried out the valuation of the fair value of the business acquired under the market approach since it has information on an observable transaction between independent parties, is duly informed and is in a free competition market. At the acquisition date, considering the amount of the value of the net assets and the consideration transferred, a gain at a bargain purchase was determined as follows: Total consideration transferred Ps. 37,046,666 U.S.$ 1,815,746 Fair value of the identifiable net assets acquired (38,317,854) (1,878,050) Gain on bargain purchase Ps. (1,271,188) U.S.$ (62,304) There was not any gain or loss in the previously held interest because the book value and the fair value of these items was zero at the acquisition date. The technique used for the measuring of the fair value of the previous held interest was the adjusted book value method. The gain on bargain purchase was recognized in other income line item in the profit or loss of the period. The gain of U.S.$62,304 (Ps. 1,271,188) was due to closing adjustments consisting of Shell’s assumption of DPRLP’s accrued expenses and taxes and the pro-rated cash. From the acquisition date to December 31, 2022, DPRLP contributed Ps. 238,940,945 to PEMEX’s total revenues and Ps. 20,905,292, to PEMEX’s total income for the period. As of December 31, 2022, PEMEX recognized Ps. (10,383,296) of currency translation effects from the investment in DPRLP into other income, as a result of derecognizing the equity method. Associates • Sierrita Gas Pipeline LLC. This company was created on June 24, 2013.

(2) On January 20, 2022, PEMEX acquired assets with a cost of Ps. 29,669,961, consisting mainly of plants. This amount includes assets acquired through a business combination (see Note 12). A. For the six-month periods ended June 30, 2023 and 2022, the financing cost identified with fixed assets in the construction or installation stage, capitalized as part of the value of such fixed assets, was Ps. 2,389,748 and Ps. 1,674,380, respectively. Financing cost rates during the six-month periods ended June 30, 2023 and 2022 were 6.47% to 7.54% and 5.40% to 6.48%, respectively. B. The combined depreciation of fixed assets and amortization of wells for the six-month periods ended June 30, 2023 and 2022, recognized in operating costs and expenses, was Ps. 56,791,178 and Ps. 69,413,993, respectively. These figures include costs related to plugging and abandonment of wells for the six-month periods ended June 30, 2023 and 2022 of Ps. 30,330 and Ps. 35,914, respectively. C. As of June 30, 2023 and December 31, 2022, provisions relating to future plugging of wells costs amounted to Ps. 60,915,126 and Ps. 66,699,388, respectively, and are presented in the “Provisions for plugging of wells” (see Note 17).

(59,536,095) 21,547,474 As of June 30, 2023, Pemex Exploration and Production recognized a net impairment of Ps. (59,536,095) mainly due to: (i) a decrease in production profiles volume in the barrel of crude oil equivalent generating a negative effect of Ps. 83,067,440, mainly in the Chuc, Crudo Ligero Marino, Tsimin Xux and Ixtal-Manik CGUs; (ii) the negative effect due to an exchange rate of Ps. 31,854,861, from Ps. 19.4143 = U.S.$1.00 as of December 31, 2022, to Ps. 17.0720 = U.S.$1.00 as of June 30, 2023 and (iii) an increase in the discount rate of Ps. 13,119,343, from 9.31% in December 31, 2022 to 10.42% in June 30, 2023, due to the increase in the debt component in the Weighted Average Cost of Capital (“WAAC”) derived from the rise in global interest rates, which impacted PEMEX's benchmark rates that oil and gas industry uses to determine these discount rates. These effects were partially offset by (i) an increase in crude oil prices, generating a positive effect of Ps. 42,858,913; (ii) a positive tax effect of Ps. 23,439,232, due to the decrease in production profiles volume in the barrel of crude oil equivalent and (iii) a positive effect of Ps. 2,207,404 due to lower freight and distribution costs. As of June 30, 2022, Pemex Exploration and Production recognized a net reversal of impairment of Ps. 21,547,474, mainly due to an increase in crude oil prices, generating a positive effect of Ps. 123,125,874, mainly in the Cantarell, Burgos and Antonio J. Bermúdez CGUs. These effects were partially offset by (i) a decrease in production volume of crude oil and higher transportation and distribution costs, resulting in a negative effect of Ps. 63,545,318; (ii) a lower exchange rate gain of Ps. 5,781,853, from a peso/U.S. dollar exchange rate of Ps. 20.5835 = U.S.$1.00 as of December 31, 2021 to Ps. 19.9847 = U.S. $1.00 as of June 30, 2022; (iii) a negative effect of Ps. 25,052,959, due to an increase in the discount rate from 5.68% to 7.41%; and (iv) a negative tax effect of Ps. 7,198,269, due to higher income as a result of an increase in hydrocarbon prices. The CGUs of Pemex Exploration and Production are investment projects in productive fields with hydrocarbon reserves associated with proved reserves. These productive hydrocarbon fields contain varying degrees of heating power consisting of a set of wells and are supported by fixed assets associated directly with production, such as pipelines, production facilities, offshore platforms, specialized equipment and machinery. Each project represents the smallest unit which can concentrate the core revenues, with clear costs and expenses that enable future cash flows (value in use) to be determined. Pemex Exploration and Production determines the recoverable amount of fixed assets based on the long-term estimated prices for Pemex Exploration and Production’s proved reserves. The recoverable amount on each asset is the value in use. To determine the value in use of long-lived assets associated to hydrocarbon extraction, the net present value of reserves is determined based on the following assumptions: As of June 30, 2023 2022 Average crude oil price 61.72 U.S.$/bl 60.99 U.S.$/bl Average gas price 4.96 U.S.$/mpc 5.09 U.S.$/mpc Average condensates price 67.57 U.S.$/bl 68.27 U.S.$/bl After-tax discount rate 10.42% annual 7.41% annual For the six-month periods ended June 30, 2023 and 2022 the total forecast production, calculated with a horizon of 25 years, was 6,685 billion barrels per day (Bbd) and 6,955 Bbd per day of crude oil equivalent, respectively. Pemex Exploration and Production, in compliance with practices observed in the industry, estimates the recovery value of an asset by determining its value in use, based on cash flows associated with proved reserves after taxes and using a discount rate, also after taxes. Cash flows related to plugging wells provision costs are excluded in this computation of discounted cash flows. As of June 30, 2023 and 2022, values in use for CGU with impairment or reversal of impairment are: 2023 2022 Aceite Terciario del Golfo Ps. 37,276,319 84,116,214 Chuc 36,565,512 83,989,635 Tsimin Xux 27,851,730 29,258,331 Ogarrio Magallanes 24,027,128 18,112,667 Crudo Ligero Marino 17,206,881 33,269,762 Antonio J.

(6,548,396) 40,823,408 As of June 30, 2023, the net impairment of Ps. (6,548,396) was due to a negative effect due to an exchange rate of Ps. 19.4143 = U.S.$1.00 as of December 31, 2022 to Ps. 17.0720 = U.S. $1.00 as of June 30, 2023. These effects were partially offset by (i) an improvement in production levels as a result of application of rehabilitation program and (ii) a slight decrease in the discount rate of CGUs of refined products by 14.16% as of December 31, 2022 to 14.10% as of June 30, 2023. As of June 30, 2022, the net reversal of impairment of Ps. 40,823,408 was mainly the result of a 26.8% increase in refining sales price. These effects were partially offset by (i) an increase in the discount rate of CGUs of refined products by 12.1% and a decrease in the discount rate of ethylene products by 2.2%; and (ii) a decrease in the exchange rate of the peso against the U.S. dollar, from a peso/U.S. dollar exchange rate of Ps. 20.5835 = U.S.$1.00 as of December 31, 2021, to Ps. 19.9847 = U.S.$1.00 as of June 30, 2022, which are used as cash flows when U.S. dollars are taken as reference. To determine the value in use of long-lived assets associated with the CGUs of Pemex Industrial Transformation, the net present value of cash flows was determined based on the following assumptions: As of June 30, 2023 2022 2023 2022 2023 2022 2023 2022 2023 2022 Refining Gas Petrochemicals Ethylene Fertilizers Average crude oil Price (U.S.$) 75.2 100.15 N.A.

N.A. = Not applicable CGUs in Pemex Industrial Transformation are processing centers grouped according to their types of processes as refineries, gas complex processors, and petrochemical centers. These centers produce various finished products for direct sale to customers or intermediate products that can be processed in another of its CGUs or by a third party. Each processing center of Pemex Industrial Transformation represents the smallest unit that has distinguishable revenues, with clear costs and expenses that enable future cash flows (value in use) to be determined. Cash flow determinations are made based on PEMEX’s business plans, operating financial programs, forecasts of future prices of products related to the processes of the CGUs, budget programs and various statistical models that consider historical information of processes and the capacity of various processing centers. The recoverable amount of assets is based on each asset’s value in use. The value in use for each asset is calculated based on discounted cash flows, taking into consideration the volumes to be produced and sales to be carried out. As of June 30, 2023 and 2022, the value in use for the impairment of fixed assets was as follows: 2023 2022 Tula Refinery Ps. 55,664,585 73,772,599 Salina Cruz Refinery 44,338,748 80,118,065 Salamanca Refinery 28,617,019 — Nuevo Pemex Gas Processor Complex 27,965,299 — Morelos Petrochemicals Complex 2,969,979 — Burgos Gas Processor Complex 965,475 — Cosoleacaque Petrochemicals Complex 858,643 — Madero Refinery 730,425 17,085,340 Minatitlán Refinery (3,168,068) 53,497,755 Poza Rica Gas Processor Complex (2,038,230) 1,504,232 Total Ps. 156,903,875 225,977,991

Disclosure Of Equity [abstract]
Equity (Deficit)	EQUITY (DEFICIT) A. Certificates of Contribution “A” The capitalization agreement between Petróleos Mexicanos and the Mexican Government states that the Certificates of Contribution “A” constitute permanent capital. For the six-month period ended June 30, 2023, Petróleos Mexicanos received Ps. 17,700,000 in Certificates of Contribution “A” from the Mexican Government. For the twelve-month period ended December 31, 2022, Petróleos Mexicanos received Ps. 188,306,717 in Certificates of Contribution “A” from the Mexican Government of which Ps. 129,018,286 were designated for the construction of the Olmeca Refinery in Dos Bocas, Paraíso, Tabasco; Ps. 45,437,539 for the strengthening of financial position and Ps. 13,850,892 for the rehabilitation plan of the National Refining System. PEMEX’s Certificates of Contribution “A” are as follows: Amount Certificates of Contribution “A” as of December 31, 2021 Ps. 841,285,576 Increase in Certificates of Contribution “A” during 2022 188,306,717 Certificates of Contribution “A” as of December 31, 2022 Ps. 1,029,592,293 Increase in Certificates of Contribution “A” during 2023 17,700,000 Certificates of Contribution “A” as of June 30, 2023 Ps. 1,047,292,293 Mexican Government contributions made in the form of Certificates of Contribution “A” during 2023 totaled Ps. 17,700,000 and were designated for the construction of the Olmeca Refinery in Dos Bocas, for the strengthening of Fertilizers chain and the rehabilitation plan of the National Refining System, as follows: Date Construction of the Olmeca Refinery Strengthening of Fertilizers chain Rehabilitation Plan of the refineries January 19 Ps. — 600,000 — January 30 — 600,000 — February 23 6,000,000 — — March 16 — — 10,500,000 Total Ps. 6,000,000 1,200,000 10,500,000 B. Mexican Government contributions During the six-month period ended June 30, 2023, there were no Mexican Government contributions apart from Certificates of Contribution “A”. During the twelve-month period ended December 31, 2022, Petróleos Mexicanos received a grant from the FONADIN in the amount of Ps. 23,000,000 for the acquisition of the remaining 50.005% interest in DPRLP (see Note 12). 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 June 30, 2023 and December 31, 2022, there were no changes to the legal reserve. D. Accumulated other comprehensive result As of June 30, 2023, the discount rate related to the liability for employee benefits carried by PEMEX was 9.21% , similar to the discount rate as of December 31, 2022 of 9.39%. Therefore, PEMEX did not make any adjustments in actuarial gains and losses. For the six -month period ended June 30, 2022 , PEMEX recognized net actuarial gains in other comprehensive income (loss) of Ps. 158,392,790; which is presented net of deferred income tax for Ps. (10,556,152), related to retirement and post-employment benefits. The variation related to retirement and post-employment benefits was the result of an increase in the discount and return on plan assets rates from 8.46% as of December 31, 2021 to 9.40% as of June 30, 2022 . E. Accumulated deficit from prior years PEMEX has recorded negative earnings in the past several years. However, the Ley de Concursos Mercantiles (“Commercial Bankruptcy Law of Mexico”) is not applicable to Petróleos Mexicanos 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 and other taxes, 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 2022 and 2023, certain ratings agencies downgraded PEMEX’s credit rating, mainly driven by the effects of COVID-19, concerns around our operating performance and the Mexican government’s ability and willingness to provide us 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 2023. These conditions have negatively impacted PEMEX´s financial performance and also its liquidity position. As of June 30, 2023 and 2022 PEMEX recognized net income of Ps. 82,159,155 and Ps. 247,649,107, respectively. In addition, as of June 30, 2023 and December 31, 2022, PEMEX had a negative equity of Ps. (1,721,218,453), and Ps. (1,768,822,225), respectively, mainly due to continuous net losses in prior years, and a negative working capital of Ps. 517,157,488 and Ps. 401,842,480, as of June 30, 2023 and December 31, 2022, 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 2023 authorized PEMEX to have a negative financial balance budget of Ps. zero. This shortfall does not consider payments of principal of PEMEX’s debt due in 2024 which will be covered by financing activities that do not represent a net debt in terms of public debt greater than Ps. 29,912,400. PEMEX has short-term debt principal maturities (including interest payable) of Ps.516,455,816 as of June 30, 2023. 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, remains through 2024, which allows PEMEX to substantially recover the value of the difference between the sale price and its international reference price, when in a scenario of oil and diesel, these are limited to the effects of inflation in the country. The reduction of the profit-sharing duty rate remains in 40.0% for 2023, the same as in 2022. During the six-month period ended June 30, 2023, PEMEX received equity contributions of Ps. 17,700,000 and issued notes totaling Ps. 41,200,000. In addition, PEMEX has plans to raise funds from the markets in accordance with prevailing conditions, to refinance its debt. Further, PEMEX has the capacity to refinance its short-term debt maturities through direct loans and revolving credit facilities and loans guaranteed by export credit agencies. PEMEX also established in conjunction with development and commercial banks Cadenas Productivas PEMEX Plus (Productive Chains Plus Program) to aid for the payment to suppliers and contractors. PEMEX's ability to refinance its short-term debt depends on factors beyond its control. The Revenue Law for 2023 also authorized PEMEX to incur a net additional indebtedness up to Ps. 29,912,400 (Ps. 27,068,400 and U.S.$142,200), which is considered as public debt by the Mexican Government and may be used to partially cover its financial balance of zero in 2023. 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 December 13, 2022, the Board of Directors of Petróleos Mexicanos approved the business plan of Petróleos Mexicanos and its Subsidiary Companies for 2023-2027 (the “2023-2027 Business Plan”). Prices of crude oil, natural gas and petroleum products showed a recovery in 2022, and they are expected to continue recover during 2023. In addition, if international values for the Mexican oil price were higher than the average price of U.S.$68.7 per barrel, the price on which the zero financial balance was built, this additional revenue would enable PEMEX to achieve its business plan objectives more quickly. Petróleos Mexicanos and its Subsidiary Entities are 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 consolidated financial statements as of June 30, 2023 and December 31, 2022 on a going concern basis. There are certain conditions that have generated important uncertainty and significant 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 consolidated statements of changes in equity (deficit) as “non-controlling interest.”
