All the rights reserved.#2Forward-Looking Statement & Cautionary Note PEMEX ® POR EL RESCATE DE LA SOBERANÍA Variations If no further specification is included, comparisons are made against the same realized period of the last year. Rounding Numbers may not total due to rounding. Financial Information Excluding budgetary and volumetric information, the financial information included in this report and the annexes hereto is based on unaudited consolidated financial statements prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board ("IFRS"), which PEMEX has adopted effective January 1, 2012. Information from prior periods has been retrospectively adjusted in certain accounts to make it comparable with the unaudited consolidated financial information under IFRS. For more information regarding the transition to IFRS, see Note 23 to the consolidated financial statements included in Petróleos Mexicanos' 2012 Form 20-F filed with the Securities and Exchange Commission (SEC) and its Annual Report filed with the Comisión Nacional Bancaria y de Valores (CNBV). EBITDA is a non-IFRS measure. We show a reconciliation of EBITDA to net income in Table 33 of the annexes to PEMEX's Results Report as of March 31, 2015. Budgetary information is based on standards from Mexican governmental accounting; therefore, it does not include information from the subsidiary companies or affiliates of Petróleos Mexicanos. It is important to mention, that our current financing agreements do not include financial covenants or events of default that would be triggered as a result of our having negative equity. Methodology We might change the methodology of the information disclosed in order to enhance its quality and usefulness, and/or to comply with international standards and best practices. Foreign Exchange Conversions Convenience translations into U.S. dollars of amounts in Mexican pesos have been made at the exchange rate at close for the corresponding period, unless otherwise noted. Due to market volatility, the difference between the average exchange rate, the exchange rate at close and the spot exchange rate, or any other exchange rate used could be material. Such translations should not be construed as a representation that the Mexican peso amounts have been or could be converted into U.S. dollars at the foregoing or any other rate. It is important to note that we maintain our consolidated financial statements and accounting records in pesos. As of September 30, 2021, the exchange rate of MXN 20.3060 = USD 1.00 is used. Fiscal Regime Beginning January 1, 2015, Petróleos Mexicanos' fiscal regime is governed by the Ley de Ingresos sobre Hidrocarburos (Hydrocarbons Revenue Law). From January 1, 2006 and to December 31, 2014, PEP was subject to a fiscal regime governed by the Federal Duties Law, while the tax regimes of the other Subsidiary Entities were governed by the Federal Revenue Law. On April 18, 2016, a decree was published in the Official Gazette of the Federation that allows assignment operators to choose between two schemes to calculate the cap on permitted deductions applicable to the Profit-Sharing Duty: (i) the scheme established within the Hydrocarbons Revenue Law, based on a percentage of the value of extracted hydrocarbons; or (ii) the scheme proposed by the SHCP, calculated upon established fixed fees, USD 6.1 for shallow water fields and USD 8.3 for onshore fields. The Special Tax on Production and Services (IEPS) applicable to automotive gasoline and diesel is established in the Production and Services Special Tax Law "Ley del Impuesto Especial sobre Producción y Servicios". As an intermediary between the Ministry of Finance and Public Credit (SHCP) and the final consumer, PEMEX retains the amount of the IEPS and transfers it to the Mexican Government. In 2016, the SHCP published a decree trough which it modified the calculation of the IEPS, based on the past five months of international reference price quotes for gasoline and diesel. As of January 1 2016, and until December 31, 2017, the SHCP will establish monthly fixed maximum prices of gasoline and diesel based on the following: maximum prices will be referenced to prices in the U.S. Gulf Coast, plus a margin that includes retails, freight, transportation, quality adjustment and management costs, plus the applicable IEPS to automotive fuel, plus other concepts (IEPS tax on fossil fuel, established quotas on the IEPS Law and value added tax). PEMEX's "producer price" is calculated in reference to that of an efficient refinery operating in the Gulf of Mexico. Until December 31, 2017, the Mexican Government is authorized to continue issuing pricing decrees to regulate the maximum prices for the retail sale of gasoline and diesel fuel, taking into account transportation costs between regions, inflation and the volatility of international fuel prices, among other factors. Beginning in 2018, the prices of gasoline and diesel fuel will be freely determined by market conditions. However the Federal Commission for Economic Competition, based on the existence of effective competitive conditions, has the authority to declare that prices of gasoline and diesel fuel are to be freely determined by market conditions before 2018. Hydrocarbon Reserves In accordance with the Hydrocarbons Law, published in the Official Gazette on August 11, 2014, the National Hydrocarbons Commission (CNH) will establish and will manage the National Hydrocarbons Information Center, comprised by a system to obtain, safeguard, manage, use, analyze, keep updated and publish information and statistics related; which includes estimations, valuation studies and certifications. On August 13, 2015, the CNH published the Guidelines that rule the valuation and certification of Mexico's reserves and the related contingency resources. As of January 1, 2010, the Securities and Exchange Commission (SEC) changed its rules to permit oil and gas companies, in their filings with the SEC, to disclose not only proved reserves, but also probable reserves and possible reserves. Nevertheless, any description of probable or possible reserves included herein may not meet the recoverability thresholds established by the SEC in its definitions. Investors are urged to consider closely the disclosure in our Form 20-F and our Annual Report to the CNBV and SEC, available at http://www.pemex.com/. Forward-looking Statements .
