Structure and Business Operations of Petroleos Mexicanos, Subsidiary Entities and Subsidiary Companies	NOTE 1. STRUCTURE 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 Decreto por el que se reforman y adicionan diversas disposiciones de la Constitución Política de los Estados Unidos Mexicanos, en Materia de Energía On August 11, 2014, the Ley de Petróleos Mexicanos Secretaría de Energía Disposiciones Generales de Contratación para Petróleos Mexicanos y sus Empresas Productivas Subsidiarias 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 the collecting, selling and trading of hydrocarbons. The Subsidiary Entities, Pemex Exploración y Producción Pemex Transformación Industrial Pemex Logística The primary purposes of the Subsidiary Entities are as follows: • Pemex Exploration and Production: This entity is in charge of 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, as well as commercializes, distributes and trades methane, ethane and propylene, directly or through others; as well as producing, distributing and trading ammonia and its derivatives and fertilizers, as well as provides related services; 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.

Authorization and Basis of Preparation	NOTE 2. AUTHORIZATION AND BASIS OF PREPARATION Authorization – On September 2 8 Statement of compliance – PEMEX prepared its unaudited condensed consolidated interim financial statements as of June 30, 2021 and December 31, 2020, and for the six-month These unaudited 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, 2020. PEMEX estimates that there is no significant impact on its unaudited condensed consolidated interim financial statements due to the seasonality of operations. These unaudited 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, 2020. A. Basis of accounting These unaudited 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) B. Going concern The unaudited 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). C. Functional These unaudited 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 32% and 35% of PEMEX’s total liabilities as of each of June 30, 2021 and December 31, 2020, 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, ca s . Mexico’s monetary policy regulator, the Banco de México Terms definition – References in these unaudited 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. D. Use of judgments and estimates The preparation of the unaudited 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 unaudited 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, 2020. 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 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.

Significant Accounting Policies	NOTE 3. SIGNIFICANT ACCOUNTING POLICIES The accounting policies applied in the preparation an In connection with the Interest Rate Benchmark Reform – Phase 2 (Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16), which became effective on January 1, 2021, the amendments address issues that might affect financial reporting as a result of reforms to IBOR interest rate benchmarks, including the effects of changes to contractual cash flows or hedging relationships arising from the replacement of IBOR interest rate benchmarks with alternative benchmark rates. The amendments provide practical relief from certain requirements in IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16 relating to: • changes in the basis for determining contractual cash flows of financial assets, financial liabilities and lease liabilities; and • hedge accounting . 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. Therefore, PEMEX has identified and is reviewing contracts, expiring after the applicable cessation dates, that could have an impact derived from the change in the aforementioned rates. PEMEX will continue working on any amendments to the contracts which may be required as a result of the transition. PEMEX has a reduced number of financial instruments (debt instruments and DFIs) referenced to floating rates in U.S. dollars with maturity and interest rate fixation after June 2023. PEMEX is currently monitoring the evolution of the IBORs transition in the market, to anticipate any negative impact that these changes could have. Once the alternative reference rates are defined, as well as the new discount curves and any other valuation parameters, PEMEX will be able to estimate the impact that such changes will have on financial instruments’ market value and financial cost.

Segment financial information	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 June 30, 2021, PEMEX’s operations were conducted through five business segments: Exploration and Production, Industrial Transformation, Logistics, the Trading Companies and Corporate and Other Operating Subsidiary Companies. Until December 31, 2020, PEMEX’s operations were also conducted through an additional business segment, Fertilizers (merged into the Industrial Transformation segment as of January 1, 2021). Due to PEMEX’s structure, there are significant amounts of inter-segment sales among the reporting segments, which are made at internal transfer prices established by PEMEX that are intended to reflect international 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. Crude oil export sales are made through the agent subsidiary company PMI CIM, to 17 major customers in various foreign markets. Approximately half of PEMEX’s crude oil is sold to Pemex Industrial Transformation. • 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 Aeropuertos y Servicios Auxiliares 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 and 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. • The fertilizers segment earns revenues from trading ammonia, fertilizers and its derivatives, mostly in the domestic market. This entity was merged into the Industrial Transformation segment as of January 1, 2021. • 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 segment related to corporate and other operating Subsidiary Companies provides administrative, financing, consulting and logistical services, as well as economic, tax and legal advice and re-insurance The following tables present the condensed financial information of these segments, after elimination of unrealized intersegment gain (loss), and include only select line items. As a result, the line items presented below may not total. The columns before intersegment eliminations include unconsolidated figures.

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 2 months in determining the final sale price, such as in the case of sales to some regions. Revenue is initially measured by 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 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 is initially measured by estimating variables such 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. Price is not distributed when there is a performance obligation, except, when there is more than one performance obligation, in which case, the price of the transaction will be assigned according to the service price established in the service order. 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, 2021 and December 31, 2020, PEMEX had accounts receivable derived from customer contracts in the amounts of Ps. 97,934,559 and Ps. 68,382,413, respectively (see Note 10-A). 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.

(2,634,598,983 ) (i) Related to our participation in TAG Pipeline Sur, S. de R.L. de C.V. 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 does not have policies to designate a calculation or valuation agent. 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 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 (cost) income, net” line item in the consolidated statement of comprehensive income. As of June 30, 2021 and December 31, 2020, 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. 10,223,377 and Ps. 16,629,978, respectively. As of June 30, 2021 and December 31, 2020, 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. For the six months periods ended June 30, 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, 2021 and December 31, 2020, PEMEX did not recognize any embedded derivatives (foreign currency or index). E. IBOR reference rates As a result of the decision made by the Financial Stability Board (FSB), the Interbank Offered Rates (IBORs), such as the LIBOR in dollars (overnight “O/N”, one week “1W”, two months “2M”, and twelve months “12M”) or the EURIBOR in Euros, are expected to cease to be published in 2022 and are expected to be replaced by alternative reference rates, based on risk-free rates 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 (one month “1M”, three months “3M”, and six months “6M”). Therefore, PEMEX has identified and is reviewing contracts expiring after the applicable cessation dates, that could be impacted by the change in the aforementioned rates. PEMEX has a reduced number of financial instruments referenced to floating rates in Euros and U.S. dollars with maturity and interest rate fixation after December 2021 and June 2023, respectively. This portfolio of financial instruments is composed of debt instruments and DFIs as shown below: Reference Rate Notional Amount As of June 30, 2021 (in millions of each currency) LIBOR 1M USD 3,232 Debt LIBOR 3M USD 594 LIBOR 6M USD 911 EURIBOR 3M USD 650 LIBOR 1M USD 2,500 DFI LIBOR 3M USD 156 LIBOR 6M USD 244 Note: Notional amounts with maturity after December 31, 2021 for Euros and after June 30, 2023 for U.S. dollars. In the event that Tasa de Interés Interbancaria de Equilibrio Reference Rate Notional Amount As of June 30, 2021 (in millions of each currency) TIIE 28D MXN 6,188 Debt TIIE 91D MXN 29,688 DFI TIIE 28D MXN 33,513 Note: Notional amounts with maturity after December 31, 2021. PEMEX’s portfolio consists of additional debt instruments that will mature during the year, as well as additional debt instruments and DFIs referenced at fixed rates, including fixed rate debt instruments and DFIs in currencies that are not listed in the tables above. PEMEX’s fixed rate portfolio will not be impacted by the IBOR transition. Currently, PEMEX is monitoring the evolution of the IBORs transition in the market, in order to anticipate any negative impact that these changes could have. Further, PEMEX will continue working on any amendments to its contracts that may be required as a result of the transition. Once the alternative reference rates are defined, as well as the new discount curves and any other valuation parameters, PEMEX will be able to estimate the impact that such changes will have on financial instruments’ market value and financial cost. Regarding PMI Trading, its credit agreements to date have incorporated flexible provisions that would help to smooth the transition to an alternative rate, in the event that LIBOR rates cease to be published prematurely. PMI Trading continuously monitors the evolution of LIBOR transition to anticipate any impact on its credit agreements and to amend the credit agreements whenever it is required.

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: June 30, 2021 2020 Average crude oil price 54.56 USD/bl 50.29 USD/bl Average gas price 4.69 USD/mpc 5.27 USD/mpc Average condensates price 63.77 USD/bl 56.67 USD/bl Discount rate 5.68% annual 6.30% annual For 2021 and 2020 the total forecast production, calculated with a horizon of 25 years was 6,401 and 6,914 million barrels of crude oil equivalent, respectively. Pemex Exploration and Production, in compliance with practices observed in the industry, estimates the recovery value of 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. As of June 30, 2021 and 2020, values in use for CGUs with impairment or reversal of impairment are: 2021 2020 Ku-Maloob-Zaap Ps. 649,487,778 841,469,387 Cuenca de Veracruz 166,211,278 103,282,178 Cantarell 137,428,547 131,401,801 Chuc 57,934,076 18,780,072 Aceite Terciario del Golfo 47,101,553 10,827,447 Antonio J.

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 cash generating units 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 cash generating units, budget programs and various statistical models that consider historical information of processes and the capacity of various processing centers.

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 fund its operations and capital expenditure programs. As a result, PEMEX’s indebtedness has increased significantly, and its working capital has deteriorated. Additionally, the significant crude oil price drop, which started in March 2020 and the negative economic impact as a result of the current global health crisis caused by the Covid-19 Additionally, in March and April 2020, and again in July 2021, certain ratings agencies downgraded PEMEX’s credit rating.
