NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

| 1. | The Company and its operations

Petróleo Brasileiro SA – Petrobras, hereinafter referred to as “Petrobras” or “company”, is a mixed capital company, under the control of the Federal Government, with an indefinite term, governed by the rules of private law - in general - and, specifically, by the Law No. 6,404, of December 15, 1976 (Brazilian Corporation Law), by Law No. 13,303, of June 30, 2016 (State-owned Companies' Legal Statute), by Decree No. 8,945, of December 27, 2016, and by its Bylaws.

Petrobras’ shares are listed on the Brazilian stock exchange (B3) in the Level 2 Corporate Governance special listing segment and, therefore, the Company, its shareholders, its managers and fiscal council members are subject to provisions under its regulation (Level 2 Regulation - Regulamento de Listagem do Nível 2 de Governança Corporativa da Brasil Bolsa Balcão – B3). These Regulations shall prevail over the statutory provisions, in the event of prejudice to the rights of the recipients of public offerings provided for in the Company's Bylaws, except in certain cases, due to a specific rule.

The Company is dedicated to prospecting, drilling, refining, processing, trading and transporting crude oil from producing onshore and offshore oil fields and from shale or other rocks, as well as oil products, natural gas and other liquid hydrocarbons. In addition, Petrobras carries out energy related activities, such as research, development, production, transport, distribution and trading of all forms of energy, as well as other related or similar activities.

Petrobras may perform any of the activities related to its corporate purpose, directly, through its wholly-owned subsidiaries, controlled companies, alone or through joint ventures with third parties, in Brazil or abroad.

The economic activities linked to its corporate purpose will be developed by the company, in a free competition with other companies, according to market conditions, observing the other legal principles and guidelines, such as the Petroleum Law (Law No. 9,478/97) and the Gas Law (Law nº 14.134/21). However, Petrobras may have its activities, as long as they are in line with its corporate purpose, guided by the Union, in order to contribute to the public interest that justified its creation, aiming at meeting the objective of the national energy policy, when:

I – established by law or regulation, as well as under agreements provisions with a public entity that is competent to establish such obligation, abiding with the broad publicly stated of such instruments; and

II – the cost and revenues thereof have been broken down and disseminated in a transparent manner.

In this case, the Company’s Investment Committee and Minority Shareholders Committee will evaluate and measure the difference between market conditions and the operating result or economic return of the obligation assumed by the company, in such a way that the Union compensates, for each fiscal year, the difference between market conditions and the operating result or economic return of the assumed obligation.

1.1. Highlights of the year

Petrobras presented positive operational results in 2024, generating value for society and its shareholders. The debt was within the gross debt level established in the Strategic Plan 2024-2028 (SP 24-28), reaching US$ 60 billion.

Total oil and gas production in 2024 was 2.7 million barrels of oil equivalent per day (boed), within the target established in SP 24-28. The main factors that resulted in this operational performance were: i) entry into operation of two new platforms in the pre-salt layer - FPSO Maria Quitéria in the Jubarte field and the FPSO Marechal Duque de Caxias in the Mero field; ii) reaching the maximum oil production capacity of the FPSO Sepetiba platform, in the Mero field; and (iii) start of commercial operation of the Natural Gas Processing Unit (UPGN), located at the Boaventura Energy Complex in Itaboraí, Rio de Janeiro. These factors offset the reduction in production due to maintenance stoppages, the decline of mature fields.

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

In 2024, according to SEC - Securities and Exchange Commission criteria, the company maintained the trajectory of significant addition of reserves, focusing on profitable assets and aligned with the search for a fair energy transition. The incorporation occurred mainly due to the continued development of the Atapu and Sépia Fields and of the performance of the assets, with emphasis on the Búzios, Itapu, Tupi and Sépia fields, in the Santos Basin. There were no relevant changes in reserves resulting from changes in the price of oil (more details in Additional information on oil and natural gas exploration and production activities – unaudited).

Petrobras also estimates reserves according to the ANP/SPE criteria (National Agency for Petroleum, Natural Gas and Biofuels / Society of Petroleum Engineers). As of December 31, 2024, proven reserves according to this criterion reached 11.7 billion barrels of oil equivalent. The main differences between the two criteria are detailed in note 4.1.

The cash provided by operational activities, besides the proceeds from finance debt and the other sources of funds were used for Property, Plant and Equipment (note 23), debt service fulfillment (that includes the prepayment of securities in the international capital market and the amortization of leases (notes 30 and 31), and used for payment of dividends (note 32).

The proposed allocation of the result to be submitted for deliberation at the 2025 Ordinary General Meeting, which considers the distribution of dividends for the 2024 financial year, is in line with the shareholder remuneration policy (note 32).

10

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

Gross debt in reais was impacted mainly by the 27.9% devaluation of the real against the dollar in 2024 (note 7).

The financial result in 2024 was mainly influenced by the loss with exchange rate variation of the real against the dollar and by the financial expenses from the enrollment to the tax settlement program, reflecting the charges and financial updates (notes 12 and 33).

In litigation, the highlight of the year was the reduction of non-accrued tax contingencies, due to the enrollment to the tax settlement program involving CIDE and PIS/COFINS on Imports (notes 19 and 23).

11

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

The annual review of actuarial liabilities with post-employment benefit plans reflected a decrease in liabilities, recognized as a counterpart in shareholders’ equity, resulting from the increase in the discount rate applied to actuarial obligations, offset, in part, by the return on guaranteeing assets marked to market and the variation of the hospital medical costs, in addition to recognition in the result of the past service cost due to the change in the health plan's funding relationship (note 18).

The review of the economic, financial and operational assumptions of Business Plan 25-29, which includes the project portfolio and reserve estimates, supported the review of the provision for decommissioning areas for the year 2024 (note 20), in addition to the devaluation of Real against the U.S. dollar. Such assumptions also impact recoverability tests (note 25). The review of the provision for decommissioning areas generated an increase in liabilities as a counterpart to property, plant and equipment (note 23) to the crude oil fields in operation and other operating expenses, mainly referring to fields in the process of being returned (note 11).

The wealth generated by the company in 2024, in the amount of R$380 billion (R$378 billion in 2023), was distributed as follows:

| 2. | Basis of preparation and presentation of financial statements

The consolidated and individual (Parent Company) financial statements have been prepared in accordance with the IFRS Accounting Standards as issued by the International Accounting Standards Board (IASB), and with the pronouncements issued by the Brazilian Accounting Pronouncements Committee (Comitê de Pronunciamentos Contábeis - CPC) that were approved by the Brazilian Securities and Exchange Commission (Comissão de Valores Mobiliários – CVM).

All relevant information related to financial statements, and only them, are presented and corresponds to the information used by the Company’s Management.

The financial statements have been prepared under the historical cost convention, except when otherwise indicated.

In preparing these financial statements, Management used judgments, estimates and assumptions that affect the application of accounting practices and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates. The relevant estimates and judgments that require a higher level of complexity are disclosed in note 4.

The Company's Board of Directors, at a meeting held on February 26, 2025, authorized the disclosure of these financial statements.

| 2.1. | Statement of added value

Brazilian corporate law requires publicly-held companies to prepare a Statement of Added Value and disclose it as an integral part of the set of financial statements.

13

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

This statement aims to present information relating to the wealth created by the company and the way in which such wealth was distributed and is presented as supplementary information for IFRS purposes.

This statement was prepared in accordance with Technical Pronouncement CPC 09 (R1) - Statement of Added Value, reviewed in February 2024 and approved by CVM Resolution 199/24.

The review generated a restatement of the Statement of Added Value between components of the wealth created (revenue, inputs acquired from third parties and depreciation, depletion and amortization) without affecting the net added value produced by the company, as follows:

| Consolidated | Parent Company
| Disclosed on 12.31.2023 | CPC 09 (R1) Effect | Restated 12.31.2023 | Disclosed 12.31.2023 | CPC 09 (R1) Effect | Restated 12.31.2023
Revenues | 694,684 | (8,159) | 686,525 | 673,061 | (8,199) | 664,862
Inputs acquired from third parties | (252,282) | (1,657) | (253,939) | (249,786) | (1,617) | (251,403)
Gross added value | 442,402 | (9,816) | 432,586 | 423,275 | (9,816) | 413,459
Depreciation, depletion and amortization | (76,020) | 9,816 | (66,204) | (79,425) | 9,816 | (69,609)
Net added value produced by the company | 366,382 | − | 366,382 | 343,850 | − | 343,850

The main changes introduced by CPC 09 (R1) that impacted the company's Statement of Added Value were:

| · | Adjustments to the net realizable value of inventories – they are no longer presented as inputs acquired from third parties and are now disclosed as other revenues;

| · | Depreciation, depletion and amortization – the portion capitalized in the company's assets is no longer presented as revenue related to the construction of assets for use and the portion used in liabilities for decommissioning areas is no longer presented as inputs acquired from third parties. Thus, depreciation, depletion and amortization now represent the amounts recognized in the statement of income for the period and normally used to reconcile the cash flow from operating activities and the net income.

| 2.2. | Functional currency

The functional currency of Petrobras and all of its Brazilian subsidiaries is the Brazilian Real, which is the currency of its primary economic environment of operation. The functional currency of the direct controlled entities that operate in the international economic environment is the U.S. dollar.

The statements of income and cash flow of investees, with a functional currency other than the Parent Company, are converted into reais at the average monthly exchange rate, assets and liabilities are translated at the final rate and other items of shareholders' equity are converted at the historical rate.

Exchange variations on investments in subsidiaries and affiliates, with a functional currency different from the Parent Company, are recorded in shareholders' equity, as a cumulative translation adjustment, and are transferred to the statement of income when investments are sold.

| 3. | Material accounting policies

For a better understanding of the recognition and measurement basis applied in the preparation of the financial statements, the accounting practices are presented in the respective notes that deal with the topics of their applications.

| 4. | Key estimates and judgements

The preparation of the consolidated financial information requires the use of estimates and judgments for certain transactions. Next is presented: (i) key judgments; and (ii) the main sources of uncertainty with a significant risk of causing material adjustments to the company's accounting estimates over the next fiscal year.

14

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

| 4.1. | Recognition of exploration costs and oil and natural gas reserves estimates

After obtaining the legal rights to explore a specific area, the Company uses the successful efforts method to recognize costs incurred in connection with the exploration and evaluation of mineral resources, before demonstrating technical and commercial feasibility of extracting those resources. This method requires a direct relationship between costs incurred and mineral resources for these costs to be characterized as assets. The types of exploration costs and their respective recognition are presented in note 26.

The moment in which the technical and commercial feasibility of extracting a mineral resource is determined requires management judgments. An internal commission of technical executives of the Company periodically reviews the conditions of each well, by analysis of geological, geophysical and engineering data, as well as economic conditions, operating methods and government regulations.

The Company considers that the technical and commercial feasibility of a mineral resource can be demonstrated when the project has all the necessary information to characterize the reservoir as a proved reserve. Costs associated with non-commercial mineral resources are recognized as expenses in the period when identified.

According to the definitions prescribed by the SEC, proved oil and natural gas reserves are those quantities of oil and gas which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically feasible from a given date, from known reservoirs and under existing economic conditions, operating methods and government regulation.

The Company also determines reserves according to the criteria of the National Agency for Petroleum, Natural Gas and Biofuels / Society of Petroleum Engineers (ANP/SPE). The main differences between these criteria and the SEC criterion are related to the use of different economic assumptions and the possibility of considering as reserves, in the ANP/SPE criteria, the volumes expected to be produced beyond the concession contract expiration date in fields in Brazil, according to the ANP technical reserves regulations.

| 4.2. | Impairment testing

| 4.2.1. | Main sources of estimation uncertainty related to impairment testing

Impairment testing involves uncertainties mainly related to: (a) the average Brent prices and to the Brazilian real/U.S. dollar average exchange rate, whose estimates are relevant to virtually all of the Company's operating segments; (b) discount rates; and (c) estimated proved and probable reserves (according to the criteria established by the ANP/SPE). A significant number of interdependent variables are derived from these key assumptions and there is a high degree of complexity in their application in determining value in use for impairment testing. Value in use is the present value of expected future cash flows expected to arise from an asset or cash-generating unit.

A sensitivity analysis for assets or CGUs most sensitive to future impairment losses or reversals in the next year is presented in note 25.

Average Brent prices and average exchange rate

The markets for crude oil and natural gas have a history of significant price volatility and, although prices can drop or increase precipitously, industry prices over the long term tends to continue being driven by market supply and demand fundamentals.

Brent prices and exchange rate projections are derived from the Strategic Plan and are consistent with market evidence, such as independent macro-economic forecasts, industry analysts and experts. Backtesting analysis and feedback processes in order to continually improve forecast techniques are also performed.

The Company’s oil price forecast model is based on a nonlinear relationship between variables reflecting market supply and demand fundamentals. This model also takes into account other relevant factors, such as the effects of the Organization of the Petroleum Exporting Countries (OPEC) decisions on the oil market, industry costs, idle capacity, oil and gas production forecasted by specialized firms, and the relationship between the oil price and the Brazilian Real/U.S. dollar exchange rate.

The process of projecting Brazilian Real/U.S. dollar exchange rate is based on econometric models that consider long-term assumptions involving observable inputs, such as commodity prices, country risk, interest rates in the United States and the value of the U.S. dollar relative to a basket of foreign currencies (U.S. Dollar Index – USDX).

Changes in the economic environment may result in changing assumptions and, consequently, the recognition of impairment losses or reversals on certain assets or CGUs. For example, the Company’s sales revenues and refining margins are directly impacted by Brent price variations, as well as Brazilian Real/U.S. dollar exchange rate variations, which also impacts our capital and operating expenditures.

Note 25 presents Brent prices and exchange rate estimates adopted by the Company.

15

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

Discount rates

The discount rates used in impairment tests reflect specific risks associated with the estimated cash flows of the assets or CGUs. For example, changes in the economic and political environment may result in higher country risk projections, causing increases in the discount rates used in impairment tests, as well as investment decisions that result in the postponement or interruption of projects considering specific risks related to non-completion or delayed start of operations.

Note 25 presents the main discount rates applied in impairment tests.

Estimated proved and probable reserves

Reserves estimates, according to the criteria established by the ANP/SPE (as set out in note 4.1) are revised at least annually, carried out based on the re-evaluation of pre-existing data and/or new information available related to the production and geology of the reservoirs, as well as changes in prices and costs used in the estimates. Revisions may also result from significant changes in the Company’s strategy for development projects or in the production capacity.

Although the Company is reasonably certain that proved reserves will be produced, the timing and amount recovered can be affected by a sort of factors including completion of development projects, reservoir performance, regulatory aspects and significant changes in long-term oil and gas price levels.

| 4.2.2. | Identifying cash-generating units for impairment testing

A cash-generating unit (CGU) represents the smaller identifiable group of assets that generate cash inflows, which are largely independent of the cash inflows of other assets or groups of assets. Identifying CGUs requires management assumptions and judgment, based on the Company’s business and management model. The level of asset disaggregation in CGUs can reach the limit of assets being tested individually.

Changes in CGUs resulting from the review of investment, strategic or operational factors, may result in changes in the interdependencies of assets and, consequently, alter the aggregation or breakdown of assets that were part of certain CGUs, which may influence their ability to generate cash and cause additional losses or reversals in the recovery of such assets. If the approval for the sale of a CGU’s component occurs between the reporting date and the date of the issuance of the consolidated financial statements, the Company reassesses whether the value in use of this component, estimated with the information existing at the reporting date, reasonably represents its fair value, net of sales expenses. Such information must include evidence of the stage at which management was committed to the sale of the CGU’s component.

The primary considerations in identifying the CGUs are set out as follows:

| a) | Exploration and Production CGUs:

| i) | Crude oil and natural gas producing properties: comprise assets related to exploration and production development of a field or a cluster (group of two or more fields) in Brazil and abroad. At December 31, 2024, there are 30 fields and 15 clusters representing different Exploration and Production CGUs in Brazil.

| ii) | Equipment not related to crude oil and natural gas producing properties: comprise assets that ceased to operate, such as platforms, drilling rigs and other assets which are not part of any CGU and are assessed for impairment separately.

| b) | Refining, transportation and marketing CGUs:

i) CGU Set of refining and logistics assets: comprises refineries, terminals and pipelines, as well as logistics assets operated by Transpetro. The combined and centralized operation of such assets aims at serving the market at the lowest overall costs and preserving the strategic value of the whole set of assets in the long term. The operational planning is made in a centralized manner and these assets are not managed, measured or evaluated by their individual results. Refineries do not have autonomy to choose the oil to be processed, the mix of oil products to produce, the markets in which these products will be traded, which amounts will be exported, which intermediaries will be received and to decide the sale prices of oil products. Operational decisions are analyzed through an integrated model of operational planning for market supply, considering all the options for production, imports, exports, logistics and inventories, seeking to maximize the Company’s global performance. The decision on new investments is not based on the individual assessment of the asset where the project will be installed, but on the additional result for the CGU as a whole. The model that supports the entire planning, used in technical and economic feasibility studies of new investments in refining and logistics, seeks to allocate a certain type of oil, or a mix of oil products, define market supply (area of influence), aiming at achieving the best integrated results. Pipelines and terminals are a complementary and interdependent portion of the refining assets, required to supply the market.

vi) Other G&LCE CGUs: valued at the smallest identifiable group of assets that generate cash inflows independent of cash inflows from other assets or other groups of assets.

Further information on impairment testing is set out in note 25.

| 4.3. | Sources of estimation uncertainty related to depreciation, depletion and amortization

As presented in note 23, assets directly related to the oil and gas production are depleted using the units of production method, calculated by monthly production over the respective developed proved reserves, except for the signature bonuses, which are calculated over total proved reserves.

Proved developed reserves are those for which recovery can be expected: (i) through existing wells, equipment and operating methods, or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and (ii) through extraction equipment and operational infrastructure installed at the time of the reserves estimate, if the extraction is carried out by means that do not involve a well.

Estimates of proved reserves volumes used in the units of production method are prepared by Company’s technicians according to the SEC definitions (as described in note 4.1). Revisions to the Company’s proved developed and undeveloped reserves impact prospectively the amounts of depreciation, depletion and amortization recognized in the statement of income and the carrying amounts of oil and gas properties assets. Information on uncertainties related to reserve volume estimates are presented in note 4.1.

Therefore, assuming all other variables remain constant, a decrease in estimated proved reserves would increase, prospectively, depreciation, depletion and amortization expense, while an increase in reserves would reduce depreciation, depletion and amortization.

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

| 4.4. | Sources of estimation uncertainty related to pension plan and other post-employment benefits

The net actuarial liability represents the Company's actuarial obligations, net of fair value of plan assets (when applicable), at present value, as described in note 18.3.2.

The actuarial obligations and net expenses related to defined benefit pension and health care post-employment plans are computed based on several financial and demographic assumptions, of which the most significant are:

a) Discount rate: comprises the projected future inflation in addition to an equivalent discounted interest rate that matches the duration of the pension and health care obligations with the future yield curve of long-term Brazilian Government Bonds; and

b) Medical costs: comprise the projected growth rates based on per capita health care benefits paid over the last five years, which are used as a basis for projections, converged to the general price inflation index within 30 years.

In conjunction with other actuarial assumptions, the discount rate and rate of variation of medical and hospital costs are reviewed annually and may differ from actual results due to changes in market and economic conditions.

The measurement uncertainties associated with the defined benefit obligation and a sensitivity analysis of discount rates and changes in medical costs are disclosed in notes 18.3.6 and 18.3.7, respectively.

| 4.5. | Sources of estimation uncertainty related to provisions for legal proceedings and contingencies

The Company is part in arbitrations and in legal and administrative proceedings involving civil, tax, labor and environmental issues arising from the normal course of its business and makes use of estimates to recognize the amounts and the probability of outflow of resources, based on reports and technical assessments from legal advisors and on management’s assessment.

These estimates are performed individually, or aggregated if there are cases with similar characteristics, primarily considering factors such as assessment of the plaintiff’s demands, consistency of the existing evidence, jurisprudence on similar cases and doctrine on the subject. Specifically for lawsuits by outsourced employees, the Company estimates the expected loss based on a statistical procedure, due to the number of actions with similar characteristics.

Arbitral, legal and administrative decisions against the Company, new jurisprudence and changes of existing evidence can result in changes on the probability of outflow of resources and on the estimated amounts, according to the assessment of the legal basis.

Note 19 provides further detailed information about contingencies and legal proceedings.

| 4.6. | Sources of estimation uncertainty related to decommissioning costs

The Company has legal obligations to remove equipment and restore onshore and offshore areas at the end of operations. Its most significant asset removal obligations relate to offshore areas. Estimates of costs for future environmental cleanup and remediation activities are based on current information about costs and expected plans for remediation. The timing of abandonment and dismantling of areas is based on the length of reserves depletion, in accordance with the ANP/SPE definitions. Therefore, revisions to reserves estimates that result in changes in the timing of reserves depletion may impact the provision for decommissioning cost. For additional information about revisions to the Company’s reserves estimates, see note 4.1.

These obligations are recognized at present value, using a risk-free discount rate, adjusted to the Company's credit risk. Changes in the discount rate can cause significant variations in the recognized amount, due to the long-term nature until abandonment.

The calculation to determine the amounts to be provisioned are complex, since: i) the obligations are long-term; ii) the contracts and regulations contain subjective definitions of the removal and remediation practices and criteria involved when the events occur; and iii) asset removal technologies and costs are constantly changing, along with regulations, environmental, safety and public relations considerations. Additionally, abandonment costs are mostly denominated in foreign currency, which may result in significant changes in the estimates due to changes in the exchange rates overtime.

The Company constantly conducts studies to incorporate technologies and procedures to optimize the process of abandonment, considering industry best practices. However, the timing and amounts of future cash flows are subject to significant uncertainty.

In the event of a total or partial sale of an interest in Exploration and Production agreements, the company remains jointly and severally liable for decommissioning costs of areas after production has ceased, if the purchaser fails to comply with this obligation, as determined by the ANP.

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

The sensitivity analysis of discount rates and other information on provision for decommissioning costs are presented in note 20.

| 4.7. | Sources of estimation uncertainty related to leases

The Company uses incremental borrowing rates to determine the present value of the lease payments, when the interest rate implicit in the lease cannot be readily determined.

The determination of incremental rates requires estimates based on corporate funding rates (obtained from the yields on bonds issued by Petrobras), which take into account the risk-free rate and the Company's credit risk premium, adjusted to reflect the specific conditions and characteristics of the lease, such as the risk of the country's economic environment, guarantees, currency and duration of the payment flow.

The present value of lease liabilities is determined based on the incremental rates estimated at the start date of each lease. Therefore, even in cases where lease agreements have similar characteristics, their cash flows may be discounted at significantly different incremental rates depending on the Company's corporate funding rates on the start date of each lease.

Note 31 presents information on lease arrangements by class of underlying assets.

| 4.8. | Sources of estimation uncertainty related to cash flow hedge accounting involving the Company’s future exports

The Company determines its “highly probable future exports” based on its current Business Plan and on short-term estimates on a monthly basis. The highly probable future exports are determined by a percentage of projected exports revenues.

The estimate of the amount of highly probable future exports considers future uncertainty regarding the Brent oil prices, oil production and demand for products in a model which optimizes the Company's operations and investments, in addition to considering the historical profile of exported volume in relation to total oil production.

As described in note 33.4.1, foreign exchange gains and losses relating to the effective portion of hedging instruments are recognized in other comprehensive income and reclassified to the statement of income within finance income (expense) in the periods when the hedged item affects the statement of income. However, if future exports for which foreign exchange gains and losses hedging relationship has been designated is no longer expected to occur, any related cumulative foreign exchange gains or losses that have been recognized in other comprehensive income from the date the hedging relationship was designated to the date the Company revoked the designation is immediately recycled from other comprehensive income to the statement of income.

For the long-term, future exports forecasts are reviewed whenever the Company reviews its Strategic Plan assumptions, while for the short-term future exports are reviewed monthly. The approach for determining highly probable future exports is reviewed annually, at least.

See note 33.4.1 for more detailed information about cash flow hedge accounting and a sensitivity analysis of the cash flow hedge involving future exports.

| 4.9. | Sources of estimation uncertainty related to income taxes

Income taxes rules and regulations may be interpreted differently by tax authorities, and situations may arise in which these interpretations differ from the Company's understanding.

Uncertainties over income taxes treatments represent the risks that the tax authority does not accept a certain tax treatment applied by the Company, mainly related to different interpretations of deductions and additions to the income taxes (Imposto de Renda sobre Pessoa Jurídica - IRPJ and Contribuição Social sobre Lucro Líquido – CSLL) calculation basis. The Company evaluates each uncertain tax treatment separately or in a group where there is interdependence in relation to the expected result.

The Company estimates the probability of acceptance of an uncertain tax treatment by the tax authority based on technical assessments by its legal advisors, considering precedent jurisprudence applicable to current tax legislation, which may be impacted mainly by changes in tax rules or court decisions which may affect the analysis of the fundamentals of uncertainty. The tax risks identified are evaluated, treated and, when applicable, follows a pre-determined tax risk management methodology.

If it is probable that the tax authorities will accept an uncertain tax treatment, the amounts recorded in the financial statements are consistent with the tax records and, therefore, no uncertainty is reflected in the measurement of current or deferred income taxes. If it is not probable that the tax authorities will accept an uncertain tax treatment, the uncertainty is reflected in the measurement of current or deferred income taxes in the financial statements.

19

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

To the extent that the Company concludes that it is unlikely that the tax authorities will accept an uncertain tax treatment, the amounts recorded in the financial statements must reflect this uncertainty in the measurement of current or deferred income taxes.

The effect of uncertainty for each uncertain tax treatment is estimated by using the method that provides the best prediction of the resolution of the uncertainty. The most probable amount method provides as an estimate the single most probable amount in a set of possible outcomes, while the expected amount method represents the sum of the amounts weighted by the probability in relation to a range of possible outcomes.

Additional information on uncertainty over income taxes treatments is disclosed in Note 17.1.

| 4.10. | Sources of estimation uncertainty related to expected credit losses

Credit losses correspond to the difference between all contractual cash flows owed to the Company and all cash flows that the entity expects to receive, discounted at the original effective interest rate. The expected credit loss of a financial asset corresponds to the average of expected credit losses weighted by the respective default risks.

Expected credit losses on financial assets are based on assumptions relating to risk of default, the determination of whether or not there has been a significant increase in credit risk, expectation of recovery, among others. The Company uses judgment for such assumptions in addition to information from credit rating agencies and inputs based on collection delays.

Notes 14.2 and 14.3 provide details on the expected credit losses recognized by the Company.

| 4.11. | Sources of estimation uncertainty related to the compensation for the surplus volume for the Transfer of Rights Agreement

As a result of the Second Bidding Round for the Surplus Volume of the Transfer of Rights Agreement under the Production Sharing regime, the Company signed amendments and new agreements in 2022 with partners in the Atapu and Sépia fields. These agreements provide, in addition to the compensation already received upon signature, possible additional amounts receivable that may be owed to the Company, according to the conditions described in note 29.3.

Additionally, over the last few years the Company has sold assets considered non-strategic and established partnerships in E&P assets aiming, among other objectives, at sharing risks and developing new technologies. Such transactions were carried out through partnerships (note 27) and divestments, with procedures aligned with current legislation and regulatory bodies. In some of these transactions, contingent receipts are also provided for, subject to contractual clauses (note 29.3).

| 5. | Climate Change

Climate change may result in both negative and positive effects for the Company. Potential negative effects of climate change for the Company are referred to as climate-related risks (climate risks). Conversely, potential positive effects arising from climate change for the Company are referred to as climate-related opportunities.

Climate risks are categorized as: (i) climate-related transition risks (transition risks); and (ii) climate-related physical risks (physical risks).

| 5.1. | Potential effects of climate risks on accounting estimates

Accounting estimates are monetary amounts in financial statements that are subject to measurement uncertainty.

The following information used in relevant accounting estimates of the Company is largely determined based on the assumptions and projections of the Petrobras Business Plan (PN):

| · | value in use for impairment of assets testing purposes (note 4.2.1);

| · | timing and costs used in measuring the provision for decommissioning costs (note 4.6);

| · | highly probable future exports used in cash flow hedge accounting involving the Company’s future exports (note 4.8); and

| · | useful life of PP&E and intangible assets used in measuring depreciation, depletion and amortization expenses (notes 23 and 24).

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

As specified in the following topic, the company considered the impacts related to climate risks in its Business Planning approved by the Board of Directors, updated each year, which includes actions to achieve its climate commitments and its ambition to neutralize its net operational emissions of Greenhouse Gases (GHG) (scopes 1[1] and 2[2]) by 2050.

The ambition and commitments above do not constitute guarantees of future performance by the company and are subject to assumptions that may not materialize and to risks and uncertainties that are difficult to predict.

| a) | Transition risk to low carbon economy

Transition risks arise from efforts to the transition to a low-carbon economy. In this category, the Company has identified the following risks that can reasonably be expected to affect its cash flows, access to financing or cost of capital:

Risk | Description | Time length (2)
Market | Increased demand for low-carbon energy and products and preference for fossil fuels with lower greenhouse gas (GHG) intensity in production processes, leading to reduced demand for oil and a consequent drop in the prices of fossil fuels. In Brazil, demand for our products may be affected, for example, by increased demand for alternative fuels, also stimulated by Public Policies integrated into the Fuel of the Future Law (1), among others. | Medium and long-term
Technological | Loss of competitiveness due to the non-implementation or implementation of ineffective or ineffective technologies to reduce emissions from our operations and products. | Medium and long-term
Regulatory | Establishment of stricter regulatory requirements regarding the control of GHG emissions and other requirements related to climate change, which may cause operational restrictions and financial penalties for our activities. In Brazil, an example is the regulation for the adoption of a carbon pricing instrument, considering the provisions of Law 15.042/2024, which institutes the Brazilian Greenhouse Gas Emissions Trading System (SBCE), resulting in additional costs for our operations. | Medium and long-term
Legal and Reputational | Litigation and/or reputational damage due to non-compliance with climate commitments. | Medium-term
(1) Legislation that aligns a series of initiatives to stimulate and guide the production of biofuels and reduce greenhouse gas emissions – GHG, including the National Sustainable Aviation Fuel Program (ProBioQAV), the National Green Diesel Program (PNDV) and the National Program for Decarbonization of Natural Gas Producers and Importers and for Incentive to Biomethane. Furthermore, it changes the maximum and minimum limits for the anhydrous ethanol blend content in gasoline and the biodiesel blend content in diesel oil and provides for the regulation and inspection of carbon dioxide capture and geological storage activities and the regulation of the production and sale of synthetic fuels. It also promotes the integration of initiatives and measures adopted within the scope of the National Biofuels Policy (RenovaBio), the Green Mobility and Innovation Program (Mover Program), the Brazilian Vehicle Labeling Program (PBEV) and the Vehicle Emissions Control Program (Proconve). (2) Criteria adopted for the time horizon: short term (1 year), medium term (between 1 and 5 years) and long term (after 5 years).

The risks above were considered in the development of the Company's Business Plan 2025-2029 (PN 25-29). Such consideration was based on the following external environment assumptions that reflect the dynamics of the energy sector:

• |  | Moderate economic growth compared to the recent past;

• |  | Shifts in consumption habits and behaviors;

• |  | Public policies focusing on mobility, air quality and adaptation of urban infrastructure to climate change;

• |  | International coordination in efforts to reduce GHG emissions;

• |  | Regulations in favor of energy transition and decarbonization, which will drive the reduction of fossil fuel consumption; and

• |  | Diffusion of end-use technologies that reduce the need for fossil fuel consumption.

[1] Direct GHG emissions that occur from sources that are owned or controlled by the company.

[2] GHG emissions from the generation of purchased electricity and steam consumed by the company, which occur at the facilities where the electricity and steam are generated.

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

As a result of this, demand and prices, both domestic and international, of the main products considered in the Strategic Plan 25-29 are negatively affected.

In 2024, the Company adopted three distinct scenarios that are used for different purposes in its planning activities. These scenarios are called Adaptation, Negotiation, and Commitment. In all of them, there is a slowdown and subsequent contraction of fossil fuel sources. The Negotiation scenario, which is used as a reference scenario for quantifying the Company's Business Plan, considers that fossil fuels, which currently represent approximately 80% of primary energy sources of the world matrix, will represent around 48% by 2050. The share of oil will decrease from the current 30% to around 20% of the world's primary energy sources.

The Brent price considered in the reference scenario of the Business Plan decreases from US$80 per barrel in 2024 to US$65 per barrel in 2050. For additional information about the behavior of the Brent price, considered in the Company's Business Plan reference scenario, please see note 25. The following table compares the oil price used in the reference scenario of the Strategic Plan for the years 2030 and 2050 with those projected in the Announced Pledges Scenario (APS) and Net Zero Emission (NZE) scenarios by the International Energy Agency (IEA), even if they are not used corporately by the company:

Brent price US$/Barrel | 2030 | 2050
PN | 65 | 65
APS | 72 | 58
NZE | 42 | 25

According to the IEA, the APS scenario considers that all climate commitments made by governments around the world, including Nationally Determined Contributions (NDCs), as well as long-term net-zero targets, will be met in full and on time, with an increase of approximately 1.7oC in temperature by 2100 (with a 50% probability of occurrence). As for the NZE scenario, according to the IEA, it presents a pathway for the global energy sector to achieve net-zero CO2 emissions by 2050, consistent with limiting the temperature increase to 1.5 °C (with at least a 50% probability of occurrence).

The Business Plan also includes Company's actions to achieve the carbon sustainability commitments, such as low-carbon Research and Development (R&D) projects and decarbonization projects for operations. These actions aim to address transition risks as well as reflect climate opportunities.

The Company's accounting estimates did not incorporate the effect of carbon pricing. Currently, due to uncertainties regarding the implementation and dynamics of the carbon market in Brazil, the Company considers it necessary to await the regulation of Law No. 15,042 of 2024, which establishes the Brazilian Greenhouse Gas Emissions Trading System (SBCE). This regulation will provide the necessary and sufficient details to reliably and reasonably assess the impact on the cash flows of Petrobras's assets and its CGUs.

a.1) Potential effects on the value in use in impairment tests

When measuring the value in use of its assets, the Company bases its cash flow projections on reasonable and supportable assumptions that represent management's best estimate of the range of economic conditions.

A faster transition to a low-carbon economy than projected in the Business Plan could result in Brent prices and demand for the Company’s products that are lower than the ones considered to estimate the value in use of the Company’s assets for impairment testing purposes.

The reduction in the value in use of the Company's assets may result in the recognition of losses due to the non-recoverability of the carrying amounts of these assets.

Given that the oil price is a variable that decisively influences the recoverable amount of assets, the Company carried out a sensitivity analysis of the effect of using the Brent prices considered in the APS and NZE scenarios, for the impairment test of the Company's E&P assets in Brazil.

Using the prices in the APS and NZE scenarios to perform a sensitivity analysis on projected gross revenues deducted of production taxes, net of income taxes, and keeping unchanged all other components, variables, assumptions and data for calculating the recoverable amount, the Company's E&P segment, regarding the impairment loss recognized by the Company, as disclosed in note 25, would have additional impairment reversal of R$ 2,710 in the APS scenario and additional impairment losses of R$ 69,505 in the NZE scenario, concentrated in the Campos basin fields.

The Company does not consider this sensitivity analysis, based on APS and NZE Brent price scenarios, to be the best estimates to determine expected effects on the recoverable amount of assets, sales revenues or net income.

22

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

Considering that the Company did not incorporate in its accounting estimates the carbon price effects, the Company carried out a sensitivity analysis of the effect of GHG emissions pricing costs on the impairment test of assets in the E&P segment in Brazil, considering a monetary charge per ton of CO2 emission starting from 2030, and the existence of free emission allowances.

In this context, using a base price of US$ 10/CO2 in 2030, US$ 49.7/CO2 in 2035, US$ 68/CO2 in 2040, US$ 84.8/CO2 in 2045, and US$ 100.3/CO2 in 2050, including gradual emission exemptions, to simulate additional cash outflows (net of income taxes), and keeping all other components, variables, assumptions and data for the calculation of recoverable amount unchanged, the E&P segment of the Parent Company would have an additional R$ 1,439 impairment loss.

The Company does not consider this sensitivity analysis of the effect of greenhouse gas emissions pricing costs on the impairment test of assets to be the best estimate to determine expected effects on the recoverable amount, neither the estimated effects on expenses nor net income.

a.2) Potential effects on decommissioning costs

Due to its operations, the Company has legal obligations to remove equipment and restore onshore and offshore areas. On December 31, 2024, the provision for decommissioning costs recognized by the Parent Company totaled R$ 161,647, as set out in Note 20. On an undiscounted basis the nominal amount would be R$ 321,709.

The estimated timing used by the Company to account for decommissioning costs are consistent with the useful lives of the related assets. The average decommissioning period of oil and gas assets weighted by the carrying amounts of such assets is 14 years.

During 2024, there were no issuances of government regulations related to climate matters that changed or had potential to change the period for decommissioning the Parent Company's assets, as well as no identification any triggers that would accelerate the expected dates for decommissioning the Company's assets due to the Company’s climate goals and ambition to neutralize GHG emissions in activities under its control (scopes 1 and 2) by 2050.

A transition to a low-carbon economy that is faster than anticipated by the Company may accelerate the timing to remove equipment and restore onshore or offshore areas. Such acceleration would increase the present value of the decommissioning obligations recognized by the Company.

To illustrate the effect of a possible acceleration of the transition to a low-carbon economy, the Company estimates that the provision for decommissioning costs would increase by R$ 6,786, R$ 22,001 and R$ 36,612 if the timing currently used were brought forward by one, three and five years, respectively. This sensitivity analysis assumed that all other components, variables, assumptions and data for calculating the provision remained unchanged. The year ranges used are not intended to be predictions of likely future events or outcomes.

a.3) Potential effects on “highly probable future exports” used in cash flow hedge accounting involving the Company's future exports

A transition to a low-carbon economy that is faster than it was anticipated by the Company may negatively effect the Company's future exports. Such effect may result in certain exports, whose foreign exchange gains or losses were designated for hedge accounting, no longer be considered highly probable, but remain forecasted, or, depending on the magnitude of the transition and its speed, cease to be considered forecasted. The consequences of such effects are described in the accounting policy of note 33.4.1 (a) involving the Company's future exports.

The calculation of “highly probable future exports” is based on the projected exports in the Business Plan, as set out in note 4.8. The Company considers only a portion of its projected exports as “highly probable future exports”. When determining future exports as highly probable, and therefore eligible as a hedged item for application of cash flow hedge accounting, the Company considers the effects related to the transition to a low-carbon economy. Carbon prices were not incorporated in such estimates.

Based on Brent prices, constant in the APS and NZE scenarios, sensitivity analyses were prepared to determine the need to reclassify exchange rate variations recorded in equity to the income statement. This sensitivity simulated a new future cash flow from exports, changing only the price variable, while keeping all other components, variables, assumptions and data unchanged. In this sensitivity analysis, it was found that it would be necessary to reclassify exchange rate losses recorded in equity to the income statement, estimated at R$61 only in the NZE scenario.

The simulations used to perform such sensitivity analysis, based on Brent prices of the scenarios APS and NZE, are not considered by the Company as the best estimates to determine expected effects of the reclassification of foreign exchange variation recorded in equity to the statement of income.

23

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

a.4) Potential effects on the useful lives of PP&E

A transition to a low-carbon economy that is faster than the Company anticipates may reduce the useful life of its assets, which could lead to an increase in annual depreciation, depletion and amortization expenses.

Assets directly related to the production of oil and gas in a contracted area are depleted using the units of production method and depreciated or amortized using the straight-line method. As of December 31, 2024, the carrying amount of these assets in operation in Brazil is R$ 560,103. Such assets do not have a useful life ending in or after 2050.

As mentioned in item “Transition risk to low carbon economy”, the reference scenario of the Strategic Plan indicates that there will be persistent global demand for oil in the coming decades. Additionally, calculations of expected production and oil and gas reserves in this scenario consider the effects of the transition to a low-carbon economy.

The Company's refining plants consist of 10 refineries in Brazil. Based on the current depreciation rates of the assets in operation applied to the respective carrying amounts at December 31, 2024, which amounts to R$ 57,096, and assuming no additional investment, these refineries would have no material depreciation amounts after 2050.

The Company estimates persistent demand for oil products in the coming decades, although decreasing, which should be progressively supplied by models with lower carbon intensity. Thus, the depreciation rates used by the Company for the refining plants are in line with the transition to a low-carbon economy.

The Gas and Energy assets in Brazil, including thermoelectric power plants, are depreciated using the linear method. Based on the current depreciation rates of the assets in operation applied to their respective carrying amounts as of December 31, 2024, totaling R$ 21,408, and assuming no additional investment, these assets would have no material depreciation amounts after 2050.

In this context, based on available information, the Company does not foresee significant changes in the useful life of its refineries, assets directly related to oil and gas production and those related to the Gas and Energy arising from the transition to a low-carbon economy. Such assets represent 92% of the Company's total assets in operation.

| b) | Physical Risks

Physical risks result from climate change that can be event-driven (acute physical risk) or from long-term shifts in climate patterns (chronic physical risk). In this category, the Company does not foresee that changes caused by climate change will have a material effect on accounting estimates, considering the risks currently identified.

| 6. | New standards and interpretations

| 6.1. | International Accounting Standards Board (IASB)

The main standards issued by the IASB that have not yet come into force and have not been adopted by the Company before December 31, 2024 are set out as follows:

These amendments comprise: clarifying the application of the ‘own-use’ requirements; permission of hedge accounting if these contracts are used as hedging instruments; and additional disclosure requirements. | January 1, 2026, retrospective application with specific transition rules.
IFRS 18 - Presentation and Disclosure in Financial Statements | IFRS 18 establishes new requirements for the presentation and disclosure of financial statements, replacing IAS 1 - Presentation of Financial Statements. Among others, new requirements were included on: a. Presentation of the statement of income, including the obligation to classify all income and expenses into one of five categories: operating, investing, financing, income taxes and discontinued operations; b. Disclosure of performance measures defined by management; c. Guidance on aggregation or disaggregation of information; and d. New disclosure requirements. In addition, certain changes were made to other standards, including accounting requirements related to the statement of cash flows, such as the exclusion of the optionality of the classification of cash flows from dividends and interest. | January 1, 2027, retrospective application with specific transition rules.
IFRS 19 - Subsidiaries without Public Accountability: Disclosures | IFRS 19 is a voluntary standard that enables eligible entities to provide reduced disclosures when applying IFRS accounting standards in their financial statements. To be eligible, at the end of the reporting period, an entity must be a subsidiary as defined in IFRS 10, must not have a public accountability and must have a parent company (ultimate or intermediate) that prepares consolidated financial statements, available for public use and complying with IFRS accounting standards. | January 1, 2027, with specific transition rules.

Regarding the amendment effective as of January 1, 2025, according to the assessment made, the Company estimates that there will be no significant effects arising from the initial application on its consolidated financial statements.

In relation to the amendments effective as of January 1, 2026, the Company is assessing the effects that they will have on its consolidated and individual financial statements.

*Issued replacing CPC 18 (R2).

**Issued replacing ICPC 09 (R2).

OCPC 10 deals with the accounting criteria for recognizing, measuring and disclosing economic events related to the participation or performance of entities in compulsory or voluntary markets for carbon credits (tCO2e, commonly called carbon credit markets), emission permits (allowances) and decarbonization credits (CBIO). The Company is evaluating the effects of the initial application of OCPC 10 on its individual and consolidated financial statements.

The expected effect of the initial application of Technical Pronouncements Revision No. 27 is the same as that presented for the respective standard issued by the IASB presented in note item 6.1.

In relation to CPC 18 (R3) and ICPC 09 (R3), in force from January 1, 2025, according to the assessments carried out, the Company does not estimate impacts upon initial application on Petrobras' individual financial statements and consolidated financial statements.

| 7. | Capital Management

The Company’s objective in its capital management is to maintain its capital structure at an adequate level in order to continue as a going concern, maximizing value to shareholders and investors. Its main source of funding is cash provided by its operating activities.

The financial strategy of the Business Plan 2025-2029 is focused on:

| • | cash generation greater than investments and financial liabilities;

| • | Investments with high returns and only approved with positive net present value in a robust scenario (Brent US$ 45/bbl);

| • | efficient and more flexible capital structure, with low leverage in challenging scenarios; and

| • | distribution of dividends according to the current shareholders remuneration policy, with the possibility of extraordinary payments.

The debt target went to a ceiling of US$75 billion, with convergence towards the level of US$65 billion.

In 2024, Petrobras achieved positive recurring adjusted EBITDA and consistency in cash generation through Operating Cash Flow (FCO), a performance that allowed a return to society through the payment of taxes and dividends.

Additionally, the company reduced gross debt by US$2,289 million in 2024, remaining within the reference range stipulated in its planning. Net debt increased by US$7,542 million. In reais, gross debt increased by 23%, while net debt increased by 49%, as shown in the table below:

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

The adjusted EBITDA adopted by Petrobras does not consider the result of certain operations, with the objective of providing an overview of the cash generation potential. Net debt represents the total financing and leasing, less cash and cash equivalents and securities. These measures are not defined in accordance with International Financial Reporting Standards - IFRS and should not be considered in isolation or as a replacement for income, debt and operating cash generation metrics in IFRS, nor be a basis for comparison with the indicators of other companies.

Total cash and cash equivalents | 20,254 | 61,613 | 3,134 | 2,562

Short-term financial investments in Brazil primarily consist of investments in funds holding Brazilian Federal Government Bonds that can be redeemed immediately, as well as reverse repurchase agreements that mature within three months as of the date of their acquisition. Short-term financial investments abroad comprise time deposits that mature in three months or less from the date of their acquisition, highly-liquid automatic investment accounts, interest checking accounts and other short-term fixed income instruments.

The main use of these funds in 2024 were for payment of dividends and share repurchase program of R$ 102,611, repayment of principal and interests related to finance debt and repayment of lease liability, amounting to R$ 88,881, as well as for acquisition of PP&E and intangible assets in the amount of R$ 79,856.

Cash and cash equivalents were mainly provided by operating activities (R$ 204,037), proceeds from finance debt (R$ 12,027), proceeds from disposal of assets - divestment (R$ 4,381) and financial compensation from co-participation agreements (R$ 1,951).

Accounting policy for cash and cash equivalents

Cash and cash equivalents comprise cash on hand, term deposits with banks and short-term highly-liquid financial investments that are readily convertible to known amounts of cash, are subject to insignificant risk of changes in value and have a maturity of three months or less from the date of acquisition.

27

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

Securities classified as amortized cost refer to investments in Brazil in post-fixed Bank Deposit Certificates with daily liquidity, with maturities between one and two years, and to investments abroad in time deposits with maturities of more than three months from the contracting date.

Accounting policy for marketable securities

The amounts invested in operations with terms of more than three months, as from the date of the agreement, are initially measured at fair value and subsequently according to their respective classifications, which are based on the way in which these funds are managed and their features of contractual cash flows:

| · | Amortized cost – financial assets that give rise, on specified dates, to cash flows represented exclusively by payments of principal and interest on the outstanding principal amount, the purpose of which is to receive its contractual cash flows. They are presented in current and in non-current assets according to their expectation of realization. Interest income from these investments is calculated using the effective interest rate method.

| · | Fair value through profit or loss – financial assets whose purpose is to receive from its sale. They are presented in current assets due to the expectation of realization within 12 months of the reporting date.

| 9. | Sales revenues

| 9.1. | Revenues from contracts with customers

Revenues from contracts with customers derive from different products sold by the Company’s operating segments, taking into consideration specific characteristics of the markets where they operate. For additional information about the operating segments of the Company, its activities and its respective products sold, see note 13.

The determination of transaction prices derives from methodologies and policies based on the parameters of these markets, reflecting operating risks, level of market share, changes in exchange rates and international commodity prices, including Brent oil prices, oil products such as diesel and gasoline, and the Henry Hub Index.

Others | 263 | 360
Foreign market | 134,418 | 130,677
Sales revenues | 490,829 | 511,994

Sales revenues of R$ 490,829, R$ 21,165 lower than in 2023 (R$ 511,994), reflecting:

Decrease in sales revenues in the domestic market, mainly due to:

| · | Lower average prices of oil products, especially diesel, gasoline and jet fuel, largely in line with the depreciation of international prices;

| · | Lower sales volume of oil products, especially: (i) for diesel, due to the increase in imports by third parties, mainly from Russia, and the increase in the mandatory blend content of biodiesel in type B diesel oil; and (ii) for gasoline, reflecting the recovery of the share of hydrated ethanol over gasoline C in flex-fuel vehicles;

| · | Lower revenue from oil, due to lower volumes sold; and

| · | Lower revenue from natural gas, due to: (i) lower demand in the non-thermoelectric sector, reflecting the effect of the opening of the natural gas market and the reduction in market share; and (ii) lower sales prices influenced by variations in Brent and the exchange rate.

The increase in revenue from exports reflects: (i) higher prices, mainly due to the devaluation of the real against the U.S. dollar in the formation of the sales price; and (ii) the largest volumes of oil exports. These factors were partially offset by: (iii) lower export volumes of oil products, mainly fuel oil.

The reduction in revenue from sales abroad reflects the lower volume of offshore trading operations, particularly fuel oil and LNG feedstocks.

In 2024, sales to two clients of the refining, transportation and marketing (RT&M) segment represented individually 15% and 10% of the Company’s sales revenues; in 2023, sales to two clients of the RT&M segment represented individually 16% and 11% of the Company’s sales revenues.

| 9.2. | Remaining performance obligations

The Company is party to sales contracts signed through December 31, 2024 with original expected duration of more than 1 year, which define the volume and timing of goods or services to be delivered during the term of the contract, and the payment terms for these future sales.

The estimated remaining values of these contracts in 2024 presented below are based on the contractually agreed future sales volumes, as well as prices prevailing at December 31, 2024 or practiced in recent sales reflecting more directly observable information:

Revenues are recognized once goods are transferred and services are provided to the customers and their measurement and timing of recognition will be subject to future demands, changes in commodities prices, exchange rates and other market factors.

The table above does not include information on contracts with original expected duration of less than one year, such as spot-market contracts, variable considerations which are constrained, and information on contracts only establishing general terms and conditions (Master Agreements), for which volumes and prices will only be defined in subsequent contracts.

In addition, electricity sales are mainly driven by demands to generate electricity from thermoelectric power plants, as and when requested by the Brazilian National Electric System Operator (ONS). These requests are substantially affected by Brazilian hydrological conditions. Thus, the table above presents mainly fixed amounts for the electricity to be available to customers in these operations.

| 9.3. | Contract liabilities

The balance of contract liabilities carried on the statement of financial position in 2024 amounted to R$ 397 (R$ 558 in 2023). This amount is classified as other current liabilities and primarily comprises advances from customers in ship and take or pay contracts to be recognized as revenue based on future sales of natural gas or following the non-exercise of the right by the customer

Accounting policy for revenues

The Company evaluates contracts with customers for the sale of oil and oil products, natural gas, electricity, services and other products, which will be subject to revenue recognition, and identifies the distinct goods and services promised in each of them.

Sales revenues are recognized when control is transferred to the client, which usually occurs upon delivery of the product or when the service is provided. At this moment, the Company satisfies the performance obligation.

Performance obligations are considered to be promises to transfer to the client: (i) good or service (or group of goods or services) that is distinct; and (ii) a series of distinct goods or services that have the same characteristics or are substantially the same and that have the same pattern of transfer to the client.

Revenue is measured based on the amount of consideration to which the Company expects to be entitled in exchange for transfers of promised goods or services to the customer, excluding amounts collected on behalf of third parties. Transaction prices are based on contractually stated prices, which reflect the Company's pricing methodologies and policies based on market parameters.

Invoicing occurs in periods very close to deliveries and rendering of services, therefore, significant changes in transaction prices are not expected to be recognized in revenues for periods subsequent to satisfaction of the performance obligation, except for some exports in which final price formation occurs after the transfer of control of the products and are subject to the variation in the value of the commodity.

Sales are carried out in short terms of receipt, thus there are no significant financing components.

Cost of sales of R$ 244,367, R$ 2,306 higher than in 2023 (R$ 242,061), highlighting the following factors:

| · | Higher costs with imported oil and production taxes, reflecting the depreciation of the real against the dollar at the time of inventory formation; and

Selling expenses of R$26,134, R$971 higher than in 2023 (R$25,163), largely reflecting higher logistics expenses related to the transportation of natural gas, mainly due to the reduction in reimbursement by third parties that use the pipelines. This factor was partially offset by the reduction in exported volumes of oil products, especially fuel oil.

| · | Salary adjustments, in accordance with the Collective Bargaining Agreement, and the process of advancing employees' job levels;

| · | Hiring new employees throughout the periods;

| · | Higher expenses with the health plan benefit, reflecting the recognition of the effect of the interim actuarial review referring to the change in co-participation benefit in 2024; and

| · | Higher expenses on third-party services, particularly data processing services, largely related to digital transformation initiatives.

Other income and expenses, net negative in R$ 44,372, R$ 24,442 higher when compared to 2023 (R$19,930), with emphasis on:

| · | Greater losses on decommissioning of returned/abandoned areas, largely due to the result of the annual review of the provision for fields with approval of returning, but with abandonment commitments still existing;

| · | Increase in expenses with pension and medical benefits, reflecting the intermediate actuarial review referring to the change in co-participation benefit in 2024; and

| · | Lower net disposal/write-offs of assets, largely due to the greater volume of asset sales operations concluded in 2023.

Net finance income (expense), negative, of R$ 82,471, R$ 70,610 higher compared to the negative result in 2023 (R$ 11,861), due to:

32

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

| · | Greater negative monetary and exchange rate indexation, basically caused by net losses from exchange rate variation, mainly due to the 27.9% devaluation of the real against the U.S. dollar in 2024 over liability exposure in U.S. dollar, when compared to the 7.2% appreciation in 2023; and

| · | Higher net finance expenses, with emphasis on: (i) expenses related to the effects of the enrollment to the tax settlement program ending legal disputes on tax litigation in 2024; and (ii) higher lease expenses, largely due to the increase in lease liabilities as a result of the chartering of platforms and other operational assets.

Accounting policy for operating segments

The information related to the Company’s operating segments is prepared based on available financial information directly attributable to each segment, or items that can be allocated to each segment on a reasonable basis. This information is presented by business activity, as used by the Company’s Board of Executive Officers (Chief Operating Decision Maker – CODM) in the decision-making process of resource allocation and performance evaluation.

The measurement of segment results includes transactions carried out with third parties, including associates and joint ventures, as well as transactions between operating segments. Transfers between operating segments are recognized at internal transfer prices derived from methodologies that considers market parameters and are eliminated only to provide reconciliations to the consolidated financial statements.

The Company's business segments disclosed separately are:

a)Exploration and Production (E&P): this segment covers the activities of exploration, development and production of crude oil, NGL (natural gas liquid) and natural gas in Brazil and abroad, for the primary purpose of supplying its domestic refineries. The E&P segment also operates through partnerships with other companies and includes holding interest in foreign entities operating in this segment.

As an energy Company with a focus on oil and gas, intersegment sales revenue refers mainly to oil transfers to the Refining, Transportation and Marketing segment, aiming to supply the Company's refineries and meet the domestic demand for oil products. These transactions are measured by internal transfer prices based on international oil prices and their respective exchange rate impacts, taking into account the specific characteristics of the transferred oil stream.

Additionally, the E&P segment obtains sales revenue from transfers of natural gas to the Gas and Low Carbon Energy segment, which processes it in its industrial units. These transactions are measured by internal transfer prices, based on the international prices charged for this commodity.

Revenue from sales to third parties mainly reflects services rendered relating to E&P activities, sales of the E&P’s natural gas processing plants, as well as the oil and natural gas operations carried out by subsidiaries abroad.

b)Refining, Transportation and Marketing (RT&M): this segment covers the refining, logistics, transport, acquisition and exports of crude oil, as well as trading of oil products, in Brazil and abroad. This segment also includes the petrochemical operations (which comprehends holding interests in petrochemical companies in Brazil), and fertilizer production.

This segment carries out the acquisition of crude oil from the E&P segment, imports oil for refinery slate, and acquires oil products in international markets taking advantage of the existing price differentials between the cost of processing domestic oil and that of importing oil products. This segment also performs the acquisition of natural gas from the G&LCE segment.

Intersegment revenues primarily reflect the sale of oil products to the distribution business at market prices and the operations for the G&LCE and E&P segments at internal transfer price.

Revenues from sales to third parties primarily reflect the trading of oil products in Brazil and the export and trade of oil and oil products by foreign subsidiaries.

c)Gas and Low Carbon Energies (G&LCE): this segment covers the activities of logistic and trading of natural gas and electricity, the transportation and trading of liquefied natural gas (LNG), the generation of electricity by means of thermoelectric power plants, as well as natural gas processing. It also includes renewable energy businesses, low carbon services (carbon capture, utilization and storage) and the production of biodiesel and its co-products.

Intersegment revenues primarily reflect the transfers of natural gas processed, liquefied petroleum gas (LPG) and NGL to the RT&M segment. These transactions are measured at internal transfer prices.

35

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

This segment purchases national natural gas from the E&P segment, from partners and third parties, imports natural gas from Bolivia and LNG to meet national demand.

Revenues from sales to third parties primarily reflect natural gas processed to distributors and to free consumers, as well as generation and trading of electricity.

d)Corporate and other businesses: comprise items that cannot be attributed to business segments, including those with corporate characteristics, in addition to distribution business. Corporate items mainly include those related to corporate financial management, trade and other receivables, allowance for credit losses, gains (losses) with derivatives (except those with commodity derivatives included in their respective segments), corporate overhead and other expenses, including actuarial expenses related to pension and health care plans for beneficiaries. Other businesses include the distribution of oil products abroad (South America).

Accounting policy for trade and other receivables

Trade and other receivables are generally classified at amortized cost, except for certain receivables classified at fair value through profit or loss, whose cash flows are distinct from the receipt of principal and interest, including receivables with final prices linked to changes in commodity price after their transfer of control.

When the Company is the lessor in a finance lease, a receivable is recognized at the amount of the net investment in the lease, consisting of the lease payments receivable and any unguaranteed residual value accruing to the Company, discounted at the interest rate implicit in the lease.

The company recognizes a provision for expected credit losses (ECL) for short-term accounts receivable from customers using a provision matrix.

The matrix is ​​based on unadjusted historical credit loss experience, when such information represents the best reasonable and sustainable information, or, adjusted, based on current observable data, to reflect the effects of current and future conditions, provided that such data is available without excessive cost or effort.

ECL is the weighted average of historical credit losses with the respective default risks, which may occur according to the weightings. The credit loss on a financial asset is measured by the difference between all contractual cash flows due to the Company and all cash flows the Company expects to receive, discounted at the original effective interest rate.

The Company measures the allowance for ECL of other trade receivables based on their 12-month expected credit losses unless their credit risk increases significantly since their initial recognition, in which case the allowance is based on their lifetime ECL.

When determining whether there has been a significant increase in credit risk, the Company compares the risk of default on initial recognition and at the reporting date.

Regardless of the assessment of credit risk, a 30-day period of default triggers the definition of significant increase in credit risk on a financial asset, unless otherwise demonstrated by reasonable and supportable information, such as the existence of contractual or financial guarantees, which have the potential to influence credit risk, thus affecting the application of the risk matrix percentages.

The Company assumes that the credit risk on the trade receivable has not increased significantly since initial recognition if the receivable is considered to have low credit risk at the reporting date. Low credit risk is determined based on external credit ratings or internal methodologies.

37

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

In the absence of controversy or other issues that may result in the suspension of collection, the Company assumes that a default occurs whenever the counterparty does not comply with the legal obligation to pay its debts when due or, depending on the instrument, when it is at least 90 days past due.

Total | 41,550 | 37,184 | 36,774 | 31,612

Oil inventories can be traded in their raw state, as well as consumed in the production process of their oil products.

Oil products mainly comprise diesel, gasoline, jet fuel and naphtha, and are generally traded.

Intermediate products are formed by streams of products that have already passed through at least one processing unit, but that still need to be processed, treated or converted to be available for sale.

Natural gas is initially processed and its derivatives are subsequently sold or transferred to thermoelectric plants and refineries, while LNG can be sold or converted into natural gas.

Biofuels mainly comprise the balances of ethanol and biodiesel inventories.

Materials, supplies and others mainly represent production inputs and operating materials that will be used in the Company's activities and are stated at average purchase cost, when this does not exceed replacement cost.

The increase in the balance of inventories in 2024, of R$4,366, refers mainly to petroleum oil products, reflecting the greater share of imported oil products in inventory formation, the lower volumes sold in the domestic and foreign markets, the greater production; and the higher costs of imports and raw materials (crude oil), following the devaluation of the real against the U.S. dollar at the time of inventory formation.

Inventories are presented deducted from losses to adjust their net realizable value, with these adjustments resulting mainly from fluctuations in international oil and oil product prices, and when constituted, they are recognized in the income statement for the year as costs of products and services sold. On December 31, 2024, there was a reversal of the provision for losses of R$214 (R$40 on December 31, 2023).

At December 31, 2024, the Company had pledged crude oil and oil products volumes as collateral for the Term of Financial Commitment (TFC) related to Pension Plans PPSP-R, PPSP-R Pre-70 and PPSP-NR Pre-70 signed by Petrobras and Fundação Petrobras de Seguridade Social – Petros Foundation in 2008, in the estimated amount of R$ 4,712 (R$ 4,773 on December 31, 2023).

Accounting policy for inventories

Inventories are determined by the weighted average cost method adjusted to the net realizable value when it is lower than their carrying amount.

Net realizable value is the estimated selling price of inventory in the ordinary course of business, less estimated cost of completion and estimated expenses to complete its sale, considering the purpose for which the inventories are held. Inventories with identifiable sales contracts have a net realizable value based on the contracted price, as, for example, in offshore operations (without physical tanking, with loading onto the ship and direct unloading at the customer) or auctions. Other items in inventory have a net realizable value based on general selling prices, considering the most reliable evidence available at the time of the estimate.

The net realizable value of inventories is determined by grouping similar items with the same characteristic or purpose. Changes in sales prices after the reporting date of the financial statements are considered in the calculation of the net realizable value if they confirm the conditions existing on that reporting date.

On December 31, 2024, the average payment term in Brazil is 31 days (32 days in 2023), while for suppliers abroad the average term is 31 days for imported products and 25 days for other goods and services (58 days for imported products and 26 days for other goods and services in 2023), approximately.

The increase in the balance of trade payables in 2024, of R$ 14,357, refers mainly to the acquisition of materials for investment, maritime transport and vessel operations and technical services and well drilling, data processing equipment and use license; the partnership agreement with the equalization/unitization of E&P fields; and the largest installment purchases net of oil and oil product payments.

Forfaiting

The Company has a program to encourage the development of the oil and gas production chain called “Mais Valor” (More Value), operated by a partner company on a 100% digital platform.

By using this platform, the suppliers who want to anticipate their receivables may launch a reverse auction, in which the winner is the financial institution which offers the lowest discount rate. The financial institution becomes the creditor of invoices advanced by the supplier, and Petrobras pays the invoices on the same date and under the conditions originally agreed with the supplier.

Invoices are advanced in the “Mais Valor” program exclusively at the discretion of the suppliers and do not change the terms, prices and commercial conditions contracted by Petrobras with such suppliers, as well as it does not add financial charges to the Company, therefore, the classification is maintained as Trade payables in Statements of Cash Flows (Cash flows from operating activities).

As of December 31, 2024, the balance advanced by suppliers, within the scope of the program, is R$ 832 (R$ 534 as of December 31, 2023) and has a payment term from 7 to 92 days and a weighted average term of 58 days (payment term from 7 to 92 days and a weighted average term of 57 days in 2023), after the contracted commercial conditions have been met.

(1) The liability includes uncertain tax treatments, see note 17.1.1 – Uncertainty of treatment of taxes on income.

Income taxes are calculated based on the rate of 15%, plus an additional Corporate Income Tax of 10% on taxable income for income tax and 9% on taxable income for social contribution on net income, considering the offset of tax losses and social contribution negative basis, limited to 30% of taxable income for the year. As from the calendar year of 2015, pursuant to the publication of Law No. 12,973/2014, income earned abroad by a direct or indirect subsidiary or affiliate, adjusted by dividends and results of equity-accounted investments, multiplied by the tax rate on net income in Brazil, comprise expenses with income tax and social contribution on net income.

Taxes on income in current assets are tax credits resulting from the Corporate Income Tax and Social Contribution calculation process, in addition to the respective negative balances calculated, mainly for the calendar years 2017 to 2019 and 2021. Current liabilities are the portion payable for the calculation of the current Corporate Income Tax and Social Contribution.

The balance of the federal tax settlement programs basically consists of the Corporate Income Tax and Social Contribution tax assessment notice inserted in the Special Tax Regularization Program (PERT) in 2017, on the full deductibility of the obligations assumed by the company in 2008 in the Terms of Financial Commitments, entered into with Petros and entities representing employees. The payment term is 145 monthly and successive installments, updated by the Selic interest rate, as of January 2018.

The balance of current assets increased mainly due to the creation of Corporate Income Tax and Social Contribution tax credits for the years 2019, 2021, 2022 and 2023, the entry of Withholding Income Tax credits on financial investments, in addition to the Selic update of Corporate Income Tax and Social Contribution tax credits. These effects were partially offset by the use of Withholding Income Tax credits on financial investments and the use of Corporate Income Tax and Social Contribution tax credits.

The balance of current liabilities increased mainly due to: (i) the return of advances of Corporate Income Tax (CIT) by the Dutch tax authorities, which was presented net in the subsidiary's liabilities; (ii) the provision for Corporate Alternative Minimum Tax (CAMT) in a subsidiary headquartered in the United States; and (iii) the addition of income abroad and transfer price in December 2024, offset by the tax benefit on the distribution of interest on capital.

The balance of deferred tax liabilities, net, shows an decrease in 2024, mainly due to exchange rate variations on loans, accounts receivable and payable, in financing and leasing contracts and annual review of the provision of decommissioning costs. These amounts were partially offset by the realization of prospecting costs and by the incentive of accelerated depreciation by unit produced.

Deferred tax credit assets were recognized based on the projection of taxable profit in subsequent years, supported by the premises of the Business Plan 2025-2029, which has as its pillars the control of debt, investments and business decisions respecting the ideal capital structure and solid governance in decision-making processes ensuring profitability, rationality and generation of value for all stakeholders.

Management considers that the deferred tax assets will be realized to the extent the deferred tax liabilities are reversed and expected taxable events occur based on its Business Plan 2025-2029.

The unrecognized tax credits abroad arise from tax losses accumulated by the subsidiaries Petrobras America Inc. and Petrobras de Valores Internacional de Espanha S.L.U., arising mainly from oil and gas exploration and production and refining activities in the United States.

An aging of the unrecognized deferred tax assets from companies abroad is set out below:

Unrecognized deferred tax assets | 87 | 912 | 1,807 | 806 | 319 | 3,931

| 17.1.1. | Uncertain tax treatments on income taxes

As of December 31, 2024, the company has uncertain tax treatments provisioned in the statement of financial position, totaling R$4,748 (R$1,598 in 2023), mainly related to the deduction of amounts paid in the calculation basis of Corporate Income Tax and Social Contribution in the country, as well as the incidence of Corporate Income Tax on transactions abroad, related to legal and administrative proceedings. Additionally, the company has uncertain tax treatments not provisioned in the statement of financial position, in Brazil and abroad, of taxes on income, in the amount of R$33,408 (R$33,802 in 2023), related to legal and administrative proceedings, as detailed in note 19.3.

The company also has other positions that may be considered uncertain tax treatments for taxes on income, in the amount of R$26,468 (R$19,668 in 2023), given the possibility of divergent interpretation by the tax authority. These uncertain tax treatments are supported by technical assessments and a tax risk assessment methodology, therefore, the company understands that such positions will be accepted by the tax authorities, as understood by the authorities that decide whether tax treatments are acceptable according to tax legislation, including judicial courts.

Therefore, on December 31, 2024, uncertain tax positions, in Brazil and abroad, amount to R$64,624 (R$55,068 in 2023), for which Petrobras will continue to defend its position.

Accounting policy for income taxes

The Company calculates income taxes in accordance with current legislation and applying the rates in effect at the end of reporting period. Income taxes expense for the period are recognized in the statement of income of the period, except when the tax arises from a transaction or event which is recognized directly in equity.

| a) | Current income taxes

Current income taxes are offset when they relate to income taxes levied on the same taxable entity and by the same tax authority, when there is a legal right and the entity has the intention to set off current tax assets and current tax liabilities, simultaneously.

42

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

Uncertain tax treatments are periodically assessed, considering the probability of acceptance by the tax authority.

| b) | Deferred income taxes

Deferred income taxes are generally recognized on temporary differences between the tax base of an asset or liability and its carrying amount. They are measured at the tax rates that are provided for in the specific legislation to apply to the period when the asset is realized or the liability is settled.

Deferred tax assets and liabilities are recognized for all deductible temporary differences and carryforward of unused tax losses or credits to the extent that it is probable that taxable profit will be available against which those deductible temporary differences can be utilized. When there are insufficient taxable temporary differences relating to the same taxation authority and the same taxable entity, a deferred tax is recognized to the extent that it is probable that the entity will have sufficient taxable profit in future periods.

Deferred tax assets and liabilities are offset when they relate to income taxes levied on the same taxable entity, when a legally enforceable right to set off current tax assets and current tax liabilities exists and when the deferred tax assets and deferred tax liabilities relate to taxes levied by the same tax authority on the same taxable entity.

(1) Other non-current taxes are classified within other non-current liabilities in the statement of financial position. (2) In 2024, the balance of current assets increased due to deferred PIS and COFINS amounts reclassified from non-current assets, as well as tax credits arising from debts included in the tax transaction, see note 17.3.

Deferred ICMS VAT tax credits result from requests for extemporaneous and undue credits, offset in accordance with the legislation of each state. They also arise from credits arising from the acquisition of assets destined for fixed assets, which are offset at the rate of 1/48, being fully amortized over 4 years.

Deferred PIS-COFINS credits refer mainly to the acquisition of goods and services for assets under construction (works in progress), since the tax legislation only allows their use after these assets enter into production, as well as the Electronic Requests for Refund (PER) of extemporaneous credits with the Federal Revenue Service of Brazil transmitted from 2017 to 2024.

Regarding Electronic Refund Requests, the Company has been filing legal actions to speed up the analysis processes by the Federal Revenue of Brazil, of which the amount of R$ 381 was approved and used in the current calculations of 2024.

Production taxes are financial compensation due by companies that produce oil and natural gas in Brazilian territory. They are composed of royalties, special participations, signature bonuses and payment for retention or occupation of area. They include the amounts referring to an agreement with the ANP to close a legal proceeding involving the recalculation of royalties and special participations relating to oil production in the Jubarte field, from August 2009 to February 2011 and from December 2012 to February 2015.

PIS and COFINS Law 9,718/98

The company filed ordinary lawsuits against the Brazilian Federal Government referring to the recovery of amounts collected as PIS/COFINS on financial income and exchange variations from assets, considering the unconstitutionality of §1 of art. 3 of Law 9.718/98, in the periods between February 1999 and January 2004.

All actions were deemed valid with final and unappealable judgment. Those relating to its incorporated company (two actions originating from its subsidiary Petroquisa) have already been paid by the Brazilian Government. Regarding the two remaining processes, both have favorable reports, and, in one of them, the Brazilian Government indicated agreement with a relevant part of the value, with a sentence still subject to appeal. The second, of greater value, awaits a court ruling regarding the Union's request to carry out a new examination to settle the amounts owed to Petrobras.

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

| 17.3 | . Enrollment to the tax settlement program

In June 2024, Petrobras enrolled to a Transaction Notice PGFN-RFB 6/2024, published by the Attorney General's Office of the Brazilian National Treasury (PGFN) and the Brazilian Federal Revenue (RFB), for the settlement of relevant litigation related to the taxation of remittances abroad, arising from the bipartition of the legal transaction agreed in a chartering contract for vessels and platforms, and in another contract for services.

The Transaction Notice provided for the settlement of debts under dispute relating to the taxation of CIDE, PIS and COFINS, from 2008 to 2013, whose updated amount on June 28, 2024, date of the enrollment, was R$ 44,957. The balance of the contingent liability related to the taxation of remittances abroad, which includes the debts relating to the taxation of CIDE, PIS and COFINS, is in note 19.3 – Contingent Liabilities.

The enrollment to this program brings economic benefits, as continuing the discussions would require further financial effort to provide and maintain judicial guarantees related to the Negotiated Legal Proceeding (NJP) agreed with the PGFN, in addition to other procedural costs and expenses.

The Transaction Notice provided for a 65% discount on the total debt, after the conversion of related judicial deposits into definitive payment. Therefore, on June 28, 2024, the Company recognized a R$ 19,849 liability in the statement of financial position, within other taxes payable, relating to CIDE, PIS, and COFINS, referring to the enrollment. The settlement of this tax liability is defined as follows:

| Consolidated
Enrollment to the program | 19,849
Use of judicial deposits | (6,653)
Use of tax credits from controlling companies | (1,294)
Indexation to the Selic interest rate | 268
Payment at the entry of the enrollment and monthly installments (cash effect) | (12,170)
Balance at December 31, 2024 | −

As part of this tax transaction is related to projects in which the Company operates in partnership in E&P consortia, Petrobras started negotiations with its partners for the reimbursement of the corresponding amounts to their respective interests, in the expected amount of R$ 2,581, which were recognized and received in December 31, 2024.

| 17.4 | . Global Minimum Tax (Pillar II)

In December 2021, the Organization for Economic Cooperation and Development (OECD) released the Pillar II model rules to ensure that multinationals companies with annual revenues exceeding €750 million pay a minimum 15% tax on income in each jurisdiction where they operate (Global Minimum Tax).

44

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

The Pillar II provide that, if the Parent Entity is located in a jurisdiction that has not implemented these set of rules, this tax will be levied on the next entity in the organizational structure located in a jurisdiction that has implemented it, following a top-down approach (Intermediate Parent Entity).

The Netherlands and Spain enacted new tax legislation to implement the Pillar II rules, effective January 2024. Singapore also implemented it, effective January 2025.

Brazil has implemented the Domestic Minimum Top-up Tax, effective January 2025, known as "additional to CSLL", applicable only to Brazilian companies. Petrobras is in the process of assessing if there is any exposure arising from this legislation and expects to complete the assessment during 2025.

Considering that, in 2024, Brazil had not implemented any Top-up tax legislation and following the top-down approach, Petrobras was subject to the Top-up Tax through its Intermediate Parent Entity, Petrobras International Braspetro B.V. (PIBBV), based in the Netherlands. Thus, in 2024, a R$ 551 (US$ 94 million) Top-up expense was recognized within income taxes, related to the Netherlands jurisdiction, where the effective tax rate did not reach the minimum 15% threshold provided for the Pillar II legislation. No material tax liability is expected in the other jurisdictions where the PIBBV has investments (including Spain).

Petrobras applied the temporary relief of deferred tax assets or liabilities arising from this new taxation, permitted by the amendments to the IAS 12 – Taxes on Income. Accordingly, the Top-up income taxes are recognized as current income taxes when incurred, without recognizing deferred tax assets or liabilities related to the Pillar II.

(1) It includes adjustments to provisions related to previous years.
(2) Amount recognized as other income and expenses - see note 11.

| 18.1.1. | Variable compensation program

The company recognizes the contribution of employees to the results achieved through two programs: a) profit sharing; and b) performance award program.

The amount established for variable compensation in 2024 is limited to 5% of adjusted EBITDA.

Profit Sharing (Participações nos lucros ou resultados - PLR)

Profit sharing is a variable remuneration mechanism that aims to share the Company's results with its employees. As of 2023, PLR became the company's main variable remuneration practice, also covering those occupying bonus positions, and providing for individual limits according to the participants' remuneration.

For of PLR approved by the Secretariat of Management and Governance of State-owned Companies (SEST), the Company needs to meet the following triggers such as:

• |  | Declaration and payment of distribution to shareholders approved by the Company’s Board of Directors;

• |  | Net income for the year and achieving at least 80% of the weighted average of a set of proposed indicators;

• |  | The total amount is limited to the lower of 6.25% of the net income and to 25% of the dividends distributed to shareholders. In 2024, the PLR calculated corresponded to 6.19% of the net income of the year, according to the average percentage of achievement of the indicators.

In 2024, the Company:

• |  | Settled R$ 2,939 (R$ 2,849 in the Parent Company), considering the agreement and individual limits according to their remuneration; and

• |  | Provisioned R$ 2,387 (R$ 2,925 in 2023), recorded in other income and expenses. In the Parent Company, the provision was R$ 2,266 (R$ 2,885 in 2023).

Performance award program (Programa de Prêmio por Desempenho - PRD)

The PRD intends to recognize the effort and individual performance of each employee to achieve the Company’s results. The amounts to be paid to each employee continues to be defined by the achievement of the key metrics (which currently are Delta Valor Petrobras - VALOR, Greenhouse Gas Emissions Target Achievement Indicator – IAGEE and Indicator of Commitment to the Environment (ICMA) and of the individual goals (performance management score for all employees, with exception of executive managers, for whom the scorecard of their respective departments will be considered).

The PRD establishes that, in order to trigger this payment, it is necessary to have a declaration and payment of distribution to shareholders approved by the Company’s Board of Directors, as well as net income for the year. The total amount is limited to a percentage of the net income or the Adjusted EBITDA for the year. This program was revised in 2023, replacing the Performance Award Program (PPP), and is complementary to Profit Sharing (PLR).

In 2024, the Company:

| · | Paid the amount of R$ 2,633 (R$ 2,231 in the Parent Company) referring to the award programs, considering compliance with the company's performance metrics and the individual performance of employees, with R$ 2,106 (R$ 1,709 in the Parent Company) referring to the previous PPP and PRD programs and R$ 527 (R$ 522 in the Parent Company) as an advance made in December of the PRD of 2024; and

46

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

| · | Provisioned the amount of R$2,548 (R$2,096 in 2023), recorded in other operating expenses, including Petrobras' current award program and other programs of the consolidated companies. At the Parent Company, the provision was R$2,032 (R$1,673 in 2023).

Accounting policy for variable compensation programs (PLR and PRD)

The provisions for variable compensation programs are recognized on an accrual basis, during the periods in which the employees provided services. They represent the estimates of future disbursements arising from past events, based on the criteria and metrics of the PRD and PLR, provided that the requirements for activating these programs are met and that the obligation can be reliably estimated.

18.2 . Termination benefits

They are those provided by the termination of the employment contract as a result of: i) the company's decision to terminate the employee's employment before the normal retirement date; or ii) the employee's decision to accept an offer of benefits in exchange for termination of employment.

Voluntary severance programs

The Company has voluntary termination programs (PDV), incentive retirement (PAI), specific termination programs for the corporate segment and for employees assigned to units in the process of divestment, which provide basically the same legal and compensation benefits.

The recognition of the provision for expenses with retirement programs occurs as employees join.

The Company deferred the payment of compensation in two installments, the first being at the time of dismissal, together with the legal severance pay, and the second, when applicable, 12 months after payment of the first installment.

On December 31, 2024, the balance of R$447 (R$692 in 2023) corresponds to 743 employees enrolled in voluntary termination programs expected to leave by December 2027, in addition to the second installment of 23 terminated employees.

18.3 . Post-employment benefits

The Company maintains a health care plan for its employees in Brazil (active and retiree) and their dependents, and five other major types of post-retirement pension benefits (collectively referred to as “pension plans”).

The balances related to post-employment benefits granted to employees are shown below:

| 18.3.1. | Nature and risks associated with defined benefit plans

Health Care Plan

The health plan, named AMS (Saúde Petrobras), is administered and operated by the Associação Petrobras de Saúde (APS), a non-profit civil association and includes prevention and health care programs. The plan offers health assistance to all current employees, retirees, pensioners and eligible family groups, in accordance with the criteria defined in the regulations and in the collective bargaining agreement, and is open to new employees.

Currently sponsored by Petrobras, Transpetro, PBIO, TBG and Termobahia, the plan is mainly exposed to the risk of increased medical costs due to inflation, new technologies, new types of coverage and a higher level of use of medical benefits. The company continually improves the quality of its technical and administrative processes, as well as the health programs offered to beneficiaries, in order to mitigate this risk.

47

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

Employees, retirees and pensioners make monthly fixed contributions to cover high-risk procedures and variable contributions referring to the cost of other medical and dental procedures, both based on the plan's contribution tables, which are defined based on parameters, such as the salary and age ranges. The plan also includes assistance with the purchase of some medicines through reimbursement or purchase and home delivery, with co-participation from the beneficiaries.

Payment of the assistance cost is made by the Company based on the beneficiaries' use. The financial participation of the company and beneficiaries in expenses is established in the regulation and in the collective bargaining agreement, being until March 31, 2024 60% (sixty percent) by the company and 40% (forty percent) by the participants.

The clause 37 – paragraph 2 of the Collective Agreement provided that, if CGPAR Resolutions No. 42/2022 and No. 49/2023 were to be revoked or amended, enabling adjustments in the health plan funding relationship, the company and union entities would discuss a new costing relationship, in order to have less impact on the remuneration/earnings of their beneficiaries (financially responsible), in accordance with the costing relationship historically adopted by Petrobras.

On April 26, 2024, the aforementioned resolutions were revoked by the CGPAR Resolution No. 52/2024 and, for this reason, the Company and the unions entered into an agreement, in June 2024, via amendment to the current collective bargaining agreement, to resume the costing relationship previously practiced, with 70% covered by Petrobras and 30% by the beneficiaries, effective since April 2024. Due to this change, the Company carried out an intermediate remeasurement of the actuarial liabilities of this plan.

Intermediate remeasurement on the health care plan

The intermediate remeasurement of this post-employment plan made in June 2024 resulted in a R$ 127 increase in actuarial liabilities, as follows: (i) a R$ 6,955 expense within other income and expenses, due to the change in the benefit costing; and (ii) a R$ 6,828 gain within other comprehensive income due to the revision of actuarial assumptions, mainly the increase in the discount rate applied to the actuarial liability, from 5.45% as of December 31, 2023 to 6.48% as of June 30, 2024, and to the reduction in the estimated change in medical and hospital medical costs, from 13.11% as of December 31, 2023 to 12.70% as of June 30, 2024.

The other actuarial assumptions used to carry out the intermediate remeasurement in the second quarter of 2024 had no change in relation to those used in the annual remeasurement made as of December 31, 2023.

Annual health plan review

On December 31, 2024, the liability was remeasured using current actuarial assumptions, the result of which is shown in table (a) of item 18.3.2 – Amounts in the financial statements related to defined benefit plans.

Pension plans

The sponsored pension plans are managed by Petros Foundation, which was constituted as a non-profit legal entity governed by private law with administrative and financial autonomy.

The pension plans are regulated by the Conselho Nacional de Previdência Complementar – CNPC, which includes all guidelines and procedures to be adopted by the plans for their management and relationship with stakeholders.

Petros periodically evaluates the plans in compliance with the supplementary pension rules in force and, when applicable, establishes measures with the objective of offering sustainability to the plans.

The net obligation with pension plans recorded by the Company is measured in accordance with the requirements of IFRS which has a different measurement methodology to that applicable to pension funds in Brazil, which are regulated by the CNPC.

The main difference between these methodologies is that, in the CNPC criterion, Petros Foundation considers the future cash flows of normal and extraordinary sponsor’s contributions, discounted to present value, while the Company considers these cash flows as they are realized. In addition, Petros Foundation sets the real interest rate based on profitability expectations and on parameters set by PREVIC - Superintendência Nacional de Previdência Complementar (National Supplementary Pension Authority), while the Company uses a rate that combines the maturity profile of the obligations with the yield curve of government bonds. Regarding the plan assets, Petros Foundation marks government bonds on the curve or through the process of marked to market, while the Company marks all of them at market value.

Represents the company's obligation, net of collateral assets and discounted to present value, calculated in accordance with the methodology established in CPC 33 (R1) - Employee Benefits (IAS 19), which differs from the accounting and actuarial practices adopted by the pension funds regulated by the Conselho Nacional de Previdência Complementar.

As of December 31, 2024, the reduction in actuarial liabilities with post-employment benefit plans basically refers to the actuarial gain of R$19,111, recognized in shareholders’ equity, with the remeasurement of the liability resulting from changes in actuarial assumptions between 2024 and 2023, mainly due to the change in the real discount rate applied to the plan liabilities, partially offset by the return, due to the mark-to-market, of the guaranteeing assets and by the change in hospital medical costs, in addition to the recognition in the result of the expense of R$6,955 for the cost of past service, resulting from the intermediate review of the health plan in the 2nd quarter of 2024.

Information on variations in the main assumptions applied to the actuarial review is set out in note 18.3.6 – Measurement uncertainties associated with the defined benefit obligation.

The movement of obligations with defined benefit pension and health plans is represented below:

c)Changes on the fair value of plan assets

Petrobras has four pension plans, PPSP-R, PPSP-NR, PPSP-R pre-70 and PPSP-NR pre-70, in the phase of consumption of the guaranteeing asset, and one plan, PP2, whose most participants is in the wealth accumulation phase.

The evolution of the guaranteeing asset reflects these characteristics of the plans, being the result of the inflow of contributions and the redemption of assets for payment of benefits, in addition to the influence of the profitability of the investments of the assets.

Investment management of pension plan assets

Petros Foundation prepares annually Investment Policies (PI) specific to each plan, following two models:

| (i) | for Petros 2, the achievement of the actuarial goal with the lowest value at risk; and

| (ii) | for defined benefit plans, the minimal mismatch in net cash flows, conditioned to the achievement of the actuarial target.

Pension plans assets follow a long-term investment strategy based on the risks assessed for each different class of assets and provide for diversification, in order to lower portfolio risk. The portfolio profile must comply with the Brazilian National Monetary Council (Conselho Monetário Nacional – CMN) regulations.

Petros Foundation establishes investment policies for 5-year periods, reviewed annually, using an asset liability management model (ALM) to address net cash flow mismatches of the benefit plans, based on liquidity and solvency parameters.

Pension plan assets by type of asset are set out as follows:

Accounting policy for post-employment defined benefits

The obligations related to post-employment defined benefit plans and health-care plans are recognized as liabilities in the statement of financial position based on actuarial calculations which are revised annually by an independent qualified actuary (updating for material changes in actuarial assumptions and estimates of expected future benefits), using the projected credit unit method, net of the fair value of plan assets, when applicable, from which the obligations are to be directly settled.

Under the projected credit unit method, each period of service gives rise to an additional unit of benefit entitlement and each unit is measured separately to determine the final obligation. Actuarial assumptions include demographic and financial assumptions, medical costs estimate, historical data related to benefits paid and employee contributions, as set out in note 4.

Service cost are accounted for within the statement of income and comprises: (i) current service cost, which is the increase in the present value of the defined benefit obligation resulting from employee service in the current period; (ii) past service cost, which is the change in the present value of the defined benefit obligation for employee service in prior periods, resulting from a plan amendment (the introduction, modification, or withdrawal of a defined benefit plan) or a curtailment (a significant reduction by the entity in the number of employees covered by a plan); and (iii) any gain or loss on settlement.

| 19. | Provisions for legal proceedings, judicial deposits and contingent liabilities

| 19.1. | Provisions for legal proceedings

The Company recognizes provisions for legal, administrative and arbitral proceedings, based on the best estimate of the costs, for which it is probable that an outflow of resources embodying economic benefits will be required and that can be reliably estimated. These proceedings mainly include:

| · | Labor claims, in particular: (i) several individual and collective labor claims; (ii) opt-out claims related to a review of the methodology by which the minimum compensation based on an employee's position and work schedule (Remuneração Mínima por Nível e Regime - RMNR) is calculated; and (iii) actions of outsourced employees.

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

In 2024, the increase in liabilities is mainly due to changes in civil litigations involving contractual issues in the supply of goods and services totaling R$2,011.

| 19.2. | Judicial deposits

The Company makes deposits in judicial phases, mainly to suspend the chargeability of the tax debt and to maintain its tax compliance. Judicial deposits are set out in the table below according to the nature of the corresponding lawsuits:

| Consolidated | Parent Company
Non-current assets | 12.31.2024 | 12.31.2023 | 12.31.2024 | 12.31.2023
Tax | 50,694 | 51,350 | 50,519 | 51,205

| 2024 | 2023 | 2024 | 2023
Opening Balance | 71,390 | 57,671 | 70,968 | 57,239
Additions | 5,358 | 8,663 | 5,093 | 8,623
Use (1) | (8,031) | (738) | (7,786) | (662)
Financial accruals and charges | 3,981 | 5,830 | 3,962 | 5,803
Others | 47 | (36) | 45 | (35)
Closing balance | 72,745 | 71,390 | 72,282 | 70,968

(1) It includes, in 2024, R$ 6,653 referring to the nominal values ​​of deposits used when enrolling to the tax settlement program, on the incidence of CIDE, PIS and Cofins on remittances abroad under a vessel and platform charter agreement as detailed in note 17.

In 2024, the Company made judicial deposits net of reversal in the amount of R$5,358, with emphasis on the deposits and the nature of the related contingencies:

| · | R$ 2,059 referring to production taxes values ​​related to the unification of production fields (Cernambi, Tupi, Tartaruga Verde and Tartaruga Mestiça);

| · | R$ 1,620 referring to the incidence of PIS and COFINS on tax amnesty programs;

| · | R$ 1,239 referring to the incidence of CIDE, PIS and COFINS related to platform leases; and

| · | R$ 1,389 referring to several deposits of tax nature.

These effects were partially offset by R$638 relating to the redemption of judicial deposits on the recalculation of production taxes (royalties and special participation) related to oil production in the Jubarte field.

The Company maintains a Negotiated Legal Proceeding (NJP) agreement with the Brazilian National Treasury Attorney General's Office (PGFN), aiming to postpone judicial deposits related to federal tax lawsuits with values exceeding R$ 200, which allows judicial discussion without the immediate disbursement.

To achieve this, the Company makes production capacity available as a guarantee from the Tupi, Sapinhoá, and/or Roncador fields. As the judicial deposits are made, the mentioned capacity is released for other processes that may be included in the NJP.

The Company’s management understands that the mentioned NJP provides greater cash predictability and ensures the maintenance of federal tax regularity. As of December 31, 2024, the balance of production capacity held in guarantee in the NJP is R$ 13,362 (R$ 38,714 as of December 31, 2023), whose reduction is due to the Company's enrollment to the tax settlement program in June 2024.

| 19.3. | Contingent liabilities

Contingent liabilities for which either the Company is unable to make a reliable estimate of the expected financial effect that might result from resolution of the proceeding, or a cash outflow is not probable, are not recognized as liabilities in the financial statements but are disclosed in the notes to the financial statements, unless the likelihood of any outflow of resources embodying economic benefits is considered remote.

The estimates of contingent liabilities are indexed to inflation and updated by applicable interest rates. As of December 31, 2024, estimated contingent liabilities for which the possibility of loss is classified as possible are set out in the following table:

As there were several legal actions at different procedural stages, the Company monitors the progress of the respective processes and makes the necessary adjustments to the values ​​and expectations of this litigation in accordance with the decisions that apply the Superior Labor Court precedent. In 2024, the reduction refers, in particular, to write-offs and transfers for remote loss resulting from favorable decisions to Petrobras that applied the Superior Labor Court precedent. | 30,553 | 40,485

Current status: The claims involve lawsuits in different judicial stages. In 2024, there was an increase in value due to new lawsuits and unfavorable decisions to Petrobras. | 20,552 | 17,171
Plaintiff: Agência Nacional de Petróleo, Gás Natural e Biocombustíveis - ANP |  |
2) Proceedings challenging an ANP order requiring Petrobras to: unite Tupi and Cernambi fields on the BM-S-11 joint venture; to unite Baúna and Piracicaba fields; and to unite Tartaruga Verde and Mestiça fields, which would cause changes in the payment of special participation charge. |  |
Current status: This list involves claims that are disputed in court and in arbitration proceedings, as follows. In 2024, there was an increase in the value, due to the judicial deposits that are made by Petrobras: a) Tupi and Cernanbi: initially, the Company made judicial deposits for the alleged differences resulting from the special participation. However, with the reversal of the favorable injunction, the payment of these alleged differences were made directly to ANP, and such judicial deposits were resumed in the 2nd Quarter of 2019. The suspension of the arbitration was reversed by the BM-S-11 Consortium at the Brazilian Superior Court, so that the arbitration resumed its progress. b) Baúna and Piracicaba: the decision maintaining the suspension of arbitration was revoked, and the arbitration procedure is ongoing. c) Tartaruga Verde and Mestiça: Petrobras was also authorized to make deposits of the disputed amounts, which continue to occur. The Federal Regional Court of the 2nd Region has so far ruled on the jurisdiction of the Arbitral Court, authorizing the continuation of the arbitration. |  |
d) Berbigão and Sururu: ANP made a decision on January 24, 2025, determining the unification of the Berbigão and Sururu fields, located in the BM-S-11A concession, in the pre-salt layer of Santos Basin, operated by Petrobras with a 42.5% interest. The decision results in the reporting of production from the Berbigão and Sururu fields in a single field, increasing the rate applied to the corresponding collection of Special Participation related to the unified field, retroactively to the date of commencement of production. In the same decision, it was determined that ANP's Superintendence of Government Participations should determine the value of Government Participations considering the unified fields.

19.3.2. Minimum Compensation Based on Employee's Position and Work Schedule (Remuneração Mínima por Nível e Regime - RMNR)

The RMNR consists of a minimum remuneration guaranteed to employees, based on salary level, work schedule and geographic location. This remuneration policy was created and implemented by Petrobras in 2007 through collective negotiation with union representatives, and approved at employee meetings, with the formula for calculating the supplement to this minimum remuneration adopted by the Company later being questioned in court by employees and Unions. The Superior Labor Court (TST) established criteria different from those agreed and reached an understanding partially contrary to the Company, deciding to exclude some portions of the calculation. The Federal Supreme Court (STF), which accepted the Company's appeal, recognized in March 2024 that the calculation formula used by the Company is valid and in accordance with what was negotiated between the parties.

The Company has been adjusting the expectation of loss, according to the decisions in which the understanding of the STF applies. As there are several legal actions at different procedural stages, the Company monitors the application of the precedent to the respective processes, which are being terminated, according to their progress in the Court.

As of December 31, 2024, there are several legal proceedings related to the Minimum Remuneration by Level and Work Regime (RMNR) reflected in the company's financial statements, with R$546 (R$ 655 as of December 31, 2023) classified as probable loss, recognized in liabilities as a provision for legal and administrative proceedings, and R$30,553 (R$ 40,485 as of December 31, 2023) classified as possible loss.

| 19.4. | Class action and related proceedings

| 19.4.1. | Class action in the Netherlands

On January 23, 2017, Stichting Petrobras Compensation Foundation ("Foundation") filed a class action in the Netherlands, at the District Court of Rotterdam, against Petróleo Brasileiro S.A. – Petrobras, Petrobras International Braspetro B.V. (PIB BV), Petrobras Global Finance B.V. (PGF), Petrobras Oil & Gas B.V. (PO&G) and some former Petrobras managers. The Foundation alleges that it represents the interests of an unidentified group of investors and asserts that, based on the facts revealed by the Lava-Jato Operation, the defendants acted illegally before the investors. On May 26, 2021, the District Court of Rotterdam decided that the class action should proceed and that the arbitration clause of Petrobras' bylaws does not prevent the Company's shareholders from having access to the Dutch Judiciary and have their interests represented by the “Foundation”. However, the interests of investors who have already started arbitration against Petrobras or who are parties to legal proceedings in which the applicability of the arbitration clause has been definitively recognized are excluded from the scope of the action.

On July 26, 2023, the Court issued an intermediary decision on the merits which provided the following understanding: (i) the requests made against PIB BV, PO&G and certain former members of the Company’s management were rejected; (ii) the Court declared that Petrobras and the PGF acted illegally in relation to their investors, although the Court expressed it does not consider itself sufficiently informed about relevant aspects of Brazilian, Argentine and Luxembourger laws to definitively decide on the merits of the action; and iii) the alleged rights under Spanish legislation are prescribed.

Regarding the aspects of Brazilian, Argentine and Luxembourger laws considered relevant to the sentence, the Court ordered the production of technical evidence by Brazilian and Argentine experts and by Luxembourger authorities.

On October 30, 2024, after the parties' comments on the technical evidence, the Court issued a ruling, in which it broadly accepted Petrobras' arguments regarding the requests presented in favor of the Company's shareholders and considered that: i) in accordance with Brazilian legislation, all damages alleged by the Foundation qualify as indirect and are not subject to compensation; and ii) according to Argentine law, shareholders cannot, in principle, request compensation from the Company for damages alleged by the Foundation, and the Foundation has not demonstrated that it represents a sufficient number of investors who could, in theory, present such a request.

Therefore, the Court rejected the Foundation's allegations in accordance with Brazilian and Argentine law, which resulted in the rejection of all requests made in favor of shareholders. With respect to certain bondholders, the Court considered that Petrobras and PGF acted illegally under Luxembourg law, while PGF acted illegally under Dutch law.

Furthermore, the Court confirmed the following issues of the decision released to the market on July 26, 2023: (i) rejection of the allegations against PIBBV, POG BV and the former CEOs of Petrobras, Maria das Graças Silva Foster and José Sérgio Gabrielli de Azevedo; and (ii) prescription of requests formulated in accordance with Spanish legislation.

The Foundation and PGF have appealed the ruling and previous interim decisions and will have the opportunity to substantiate their own appeals and respond to each other's appeals, before judgment by the Court of Appeal in The Hague. Petrobras will still be able to present its own appeal within the deadline for responding to the Foundation's appeal.

In relation to bondholders, the Foundation cannot claim compensation under the class action, which will depend not only on a final result favorable to the interests of the investors in the class action, but also on the filing of subsequent actions by or on behalf of the investors by the Foundation itself, an opportunity in which Petrobras will be able to offer all the defenses already presented in the class action and others that it deems appropriate, including in relation to the occurrence and quantification of any damages that must be proven by the potential beneficiaries of the decision or by the Foundation. Any compensation for the alleged damages will only be determined by court decisions in subsequent actions.

This class action involves complex issues and the outcome is subject to substantial uncertainties, which depend on factors such as: the scope of the arbitration clause of the Petrobras Bylaws, the jurisdiction of the Dutch courts, the scope of the agreement that ended the Class Action in the United States, the Foundation's legitimacy to represent the interests of investors, the several laws applicable to the case, the information obtained from the production phase of evidence, the expert analyses, the timetable to be defined by the Court and the judicial decisions on key issues of the process, possible appeals, including before the Dutch Supreme Court, as well as the fact that the Foundation seeks only a declaratory decision in this class action.

The Company, based on the assessments of its advisors, considers that there are not enough indicative elements to qualify the universe of potential beneficiaries of a possible final decision unfavorable to Petrobras' interests, nor to quantify the supposedly compensable damages.

Thus, it is currently not possible to predict whether the Company will be liable for the effective payment of damages in any future individual claims, as this analysis will depend on the outcome of these complex procedures. In addition, it is not possible to know which investors will be able to bring subsequent individual actions related to this matter against Petrobras.

Furthermore, the claims formulated are broad, cover a multi-year period and involve a wide variety of activities and, in the current scenario, the impacts of such claims are highly uncertain. The uncertainties inherent in all of these issues affect the value and duration of final resolution of this action. As a result, Petrobras is unable to estimate an eventual loss resulting from this action. However, Petrobras continues to reject the Foundation's allegations, in relation to which it was considered a victim by all Brazilian authorities, including the Brazilian Supreme Federal Court.

Petrobras and its subsidiaries reject the allegations made by the Foundation and will continue to defend themselves vigorously.

| 19.4.2. | Arbitration and other legal proceedings in Argentina

In relation to the arbitration in Argentina, the Argentine Supreme Court denied the appeal, but the Consumidores Damnificados Asociación Civil para su Defensa (formerly Consumidores Financieros Asociación Civil, "Association") filed a new appeal to the Argentine Supreme Court, which was also denied, thus the arbitration was sent to the Arbitration Court. This arbitration discusses Petrobras' liability for an alleged loss of market value of Petrobras' shares in Argentina, as a result of the so-called Lava Jato Operation. The Company does not have elements that allow it to provide a reliable estimate of the potential loss in this arbitration.

In parallel to such arbitration, the Association also initiated a collective action before the Civil and Commercial Court of Buenos Aires, in Argentina, with Petrobras appearing spontaneously on April 10, 2023, within the scope of which it alleges Petrobras' responsibility for an alleged loss of the market value of Petrobras' securities in Argentina, as a result of allegations made within the scope of Lava Jato Operation and their impact on the company's financial statements prior to 2015. Petrobras presented its defense on August 30, 2023. Petrobras denies the allegations presented by the Association and will defend itself against the accusations made by the author of the class action. The Company does not have elements that allow it to provide a reliable estimate of the potential loss in this arbitration.

Regarding criminal proceeding in Argentina related to an alleged fraudulent offer of securities, aggravated by the fact that Petrobras allegedly declared false data in its financial statements prior to 2015, the Court of Appeals revoked, on October 21, 2021, the lower court decision that had recognized Petrobras' immunity from jurisdiction and recommended that the lower court judge take steps to certify whether the Company could be considered criminally immune in Argentina for further reassessment of the issue. After carrying out the steps determined by the Court of Appeals, on May 30, 2023, the lower court denied the recognition of immunity from jurisdiction to Petrobras.

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

Petrobras filed an appeal against this decision, which was recognized by the Court of Appeals on April 18, 2024. Against this decision, the Association filed a new appeal, and on December 20, 2024, the Court of Cassation reformed the decision of the Court of Appeals to deny Petrobras' immunity from jurisdiction, which, in turn, appealed to the Supreme Court to reinstate the Court of Appeals decision. On December 27, 2024, before the decision of the Court of Cassation became final, the court of first instance ordered to sue Petrobras and a precautionary injunction, which was appealed to the Court of Appeals. The Court of Appeals had already recognized that the Association could not act as a representative of financial consumers, due to the loss of its registration with the competent Argentine bodies, which was also the subject of an appeal upheld by the Court of Appeals on September 15, 2022, recognizing the Association the right to represent financial consumers. The company's appeal against this decision was rejected on February 21, 2025. Petrobras presented other procedural defenses, which may be re-discussed in later stages of the process. This criminal action is being processed before the Economic Criminal Court No. 2 of the city of Buenos Aires.

As for the other criminal action for alleged non-compliance with the obligation to publish a “press release” in the Argentine market about the existence of a class action filed by Consumidores Damnificados Asociación Civil para su Defensa before the Commercial Court, there are no developments in 2024.

| 19.4.3. | Lawsuit in United States regarding Sete Brasil Participações S.A (“Sete”)

The EIG Energy Fund XIV, L.P. and affiliates (“EIG”) filed a lawsuit against Petrobras, before the District Court of Columbia, United States, to recover alleged losses related to its investment in Sete Brasil Participações S.A. On August 8, 2022, the judge upheld EIG's claim as to Petrobras' responsibility for the alleged losses (which was recorded in 2022 as provisions for legal proceedings) but denied the motion for summary judgment with respect to damages, whereby the award of compensation will be subject to the proof of damages by EIG at a hearing and to the consideration of the defenses by the Company. In the same decision, whose effects were recognized in the Company's financial statements in 2022, the judge denied the request to dismiss the case based on Petrobras' immunity from jurisdiction, when an appeal was filed with the Federal Court of Appeals for the District of Columbia, which was denied in June 2024. Petrobras then submitted a request to review the issue, which was rejected on July 24, 2024. As a result, the process, which had been suspended by the lower court judge on October 26, 2022 due to the filing of the appeal by Petrobras, resumed its course and the beginning of the trial hearing was scheduled for March 31, 2025.

On August 26, 2022, on another procedural front initiated by the EIG, the District Court of Amsterdam granted a precautionary measure to block certain Petrobras assets in the Netherlands. This granting was based on the decision of the District Court of Columbia, on August 8, 2022, and was intended to ensure the satisfaction of EIG's claims contained in the aforementioned US lawsuit. For the purpose of this injunction, the District Court of Amsterdam limited EIG's claims to a total of US$ 297.2 million, although the US Court ruled that any award of damages would depend on evidence of damages by EIG at a trial hearing. There are some discussions about the scope of the assets blocked by EIG, but there is no related lawsuit pending in the Netherlands. This precautionary block does not prevent Petrobras and its subsidiaries from complying with their obligations to third parties.

| 19.5. | Arbitrations proposed by non-controlling shareholders in Brazil

Petrobras is also currently a party to seven arbitrations proceedings before the Market Arbitration Chamber (Câmara de Arbitragem do Mercado - CAM), linked to the Brazilian Stock Exchange (B3), brought by investors who purchased Petrobras’ shares traded on B3. Six of these arbitrations were initiated by national and foreign investors. The other proceeding was brought by an association that is not a shareholder of the Company and intended to be a collective arbitration, through representation of all non-controlling shareholders of Petrobras that acquired shares on B3 between January 22, 2010 and July 28, 2015. Investors claim alleged financial losses caused by facts related to the investigations of the so-called Lava Jato investigation.

These claims involve complex issues that are subject to substantial uncertainties and involve factors such as the novelty of the legal theories, the timing of the Chamber of Arbitration decisions, the information produced in discovery, besides analysis by retained experts.

The claims asserted are broad and span a multi-year period. The uncertainties inherent in all such matters affect the amount and timing of their ultimate resolution. As a result, the Company does not have elements that allow it to provide a reliable estimate of the potential loss in this arbitration.

Depending on the outcome of the remaining complaints, the Company may have to pay substantial amounts, which may have a significant effect on its consolidated financial position, financial performance and cash flows in a certain period. However, Petrobras does not recognize responsibility for the losses alleged by investors in these arbitrations.

These arbitrations are in different stages of processing.

In relation to one of the arbitrations, proposed by two institutional investors, on May 26, 2020, a partial award was issued which generally recognized the Company's responsibility, but not determined the payment of amounts by Petrobras. Against these decisions, Petrobras filed a lawsuit for the annulment of the partial arbitral award on July 20, 2020, as the Company understands that the award contains serious flaws

66

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

and improprieties. On November 11, 2020, the 5th Business Court of Rio de Janeiro annulled the partial arbitration award, recognizing the serious flaws and improprieties pointed out by Petrobras. At the moment, the ruling is awaited after the appeals filed at the time have been judged. The appeals against this decision are still pending judgement of a final decision. In compliance with CAM rules, the lawsuit is confidential and only available to those involved in the original arbitration proceeding.

On September 11, 2024, in the arbitration that was intended to be collective, a final arbitration ruling was handed down, in favor of Petrobras, extinguishing the referred arbitration, without resolution on the merits, due to the applicant's active illegitimacy to act as a procedural substitute. The arbitration is confidential, having become final on November 29, 2024.

In turn, on January 9, 2025, in another of these arbitrations initiated by several foreign investors, a final arbitration award was handed down in favor of Petrobras. The sentence dismissed the request, accepting one of the defense theses presented by Petrobras, recognizing that, based on Brazilian law, there is no legal permit that authorizes investors to bring an action for compensation against the Company for indirect damages, such as those related to the devaluation of the value of shares. This arbitration is confidential, as are the others in progress.

Petrobras will continue to defend itself in this and other arbitrations.

Accounting policy for provisions for legal proceedings, contingent liabilities and contingent assets

The Company recognizes provisions for legal, administrative and arbitration proceedings when the technical assessment of its legal advisors and the judgment of management consider that it is more likely than not that a present obligation exists and the other conditions to recognize a provision are met, including that it is probable that an outflow of resources will be required to settle the obligation.

Contingent liabilities are not recognized but are disclosed in notes when the likelihood of outflows is possible, including those whose amounts cannot be estimated, considering the best information available to the date of the issuance of these financial statements.

The methodology used to estimate the provisions is described in note 4.5.

Contingent assets are not recognized, but are disclosed in notes when the inflow of economic benefits is considered probable and the amount is considered material. However, if the inflow of economic benefits is virtually certain, which, in general, considers the final and unappealable decision, and if the value can be reliably measured, the related asset is not a contingent asset anymore and it is recognized.

| 20. | Provision for decommissioning costs

The table below details the provision for decommissioning costs amount per production area:

| Consolidated | Parent Company
| 12.31.2024 | 12.31.2023 | 12.31.2024 | 12.31.2023

Others | 130 | (38) | − | −
Closing balance | 162,253 | 112,330 | 161,647 | 111,828

The increase in the total balance of the provision in 2024 is mainly due to: (i) the review of tariffs and the duration of activities related to the decommissioning of wells and equipment; (ii) the devaluation of the real against the US dollar, with an impact on cost estimates in dollar; and iii) the reduction of the risk-adjusted real discount rate to 4.56% p.a. (4.79% in 2023).

The transfer to liabilities held for sale refers to the creation and review of the provision associated with E&P assets in process of divestment and classified as assets held for sale. In 2024, it includes the provision created for the Cherne Cluster (R$3,875), in Rio de Janeiro, for the Pescada Cluster (R$266), in Rio Grande do Norte, and the reduction due to the termination of the divestment agreement for the Uruguá Cluster, Uruguá and Tambaú fields (R$1,974), in Rio de Janeiro. In 2023, the movements refer to the provision created for the Uruguá Cluster (R$1,888) and the reduction of the provision related to the Pescada Cluster (R$205), according to note 29.

The estimated maturity of the obligations are presented below:

| Consolidated
Maturity | 2025 | 2026 | 2027 | 2028 | 2029 | 2030 onwards | 12.31.2024
Provision for decommissioning costs | 10,500 | 16,059 | 13,329 | 14,491 | 10,677 | 97,197 | 162,253
Total | 10,500 | 16,059 | 13,329 | 14,491 | 10,677 | 97,197 | 162,253

The effect of a change in the discount rate (key premise) may cause material variations in the provision, as follows:

Sensitivity to the discount rate (1) | Effects on provision for decommissioning costs | Effects on carrying amounts of assets | Effects on other income and expenses
Increase of 0.5 percentage points | (10,097) | (9,191) | (906)
Decrease of 0.5 percentage points | 11,119 | 10,090 | 1,029
(1) It includes liabilities held for sale. |  |  |

Accounting policy for decommissioning costs

The initial recognition of legal obligations to remove equipment and restore land or sea areas at the end of operations occurs after the declaration of commercial feasibility of an oil and gas field. The calculations of the cost estimates for future environmental removals and recoveries are complex and involve significant uncertainties (as set out in note 4.6).

The estimates of decommissioning costs are reviewed annually based on current information on expected costs and recovery plans.

When the revision of estimates results in an increase in the provision for decommissioning costs, the counterpart is an increase in the corresponding asset. Otherwise, if it results in a reduction in the provision, the counterpart is a reduction in the asset, which cannot exceed its book value. The excess portion is immediately recognized in profit or loss under other operating expenses, as well as the counterpart for oil and gas production fields in the process of being returned.

In 2024, the increase of R$6,275 in the balance of other assets is mainly due to advances for the acquisition of investment materials, for the construction of platforms and the greater availability and amounts receivable from partners in E&P partnership operations operated by Petrobras.

The following references detail the nature of the operations that make up the balances of other assets and liabilities:

68

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

a) Amounts deposited for payment of obligations related to the finance agreement with China Development Bank, as well as margin in guarantee for futures and over-the-counter derivatives. In addition, there are amounts in investment funds from escrow accounts related to divestment of Transportadora Associada de Gás S.A. (TAG) and in Nova Transportadora do Sudeste S.A. (NTS).

b) The balance mainly comprises advances for the construction of platforms P-80, P-82, P-83, P-84 and P-85 and for the acquisition of underwater oil and gas production and flow equipment. For each of the agreements related to these advances, the Company has an associated guarantee capable of fully covering the amount advanced by Petrobras, which includes bank guarantees, letters of credit, guarantee insurance and/or corporate guarantees.

c) Spending on platform charters and equipment rentals when the start of operations has been postponed due to legal requirements or to the need for technical adjustments.

d) Fair value of open positions and transactions closed but not yet settled.

e) Cash and amounts receivable from partners in E&P consortia operated by Petrobras.

f) Provisions for contractual indemnities and financial reimbursements assumed by Petrobras to be made to the acquirer, referring to abandonment costs of divested assets. The settlement of these provisions follows decommissioning schedules, with payments beginning between two and three months after the date expected for the execution of operations, according to the contractual terms for reimbursement of abandonment of the respective oil fields.

g) Retained amounts from obligations with suppliers to guarantee the execution of the contract, accounted for when the obligations with suppliers are due. Contractual retentions will be paid to suppliers at the end of the contract, upon issuance of the contract termination term.

h) Amounts related to the advances or cash receipt from third parties, related to the sale of products or services.

i) Accrued amounts for environmental compensation assumed by the Company in the course of its operations and research projects.

j) Non-current portion of other taxes (see note 17).

k) Dividends made available to shareholders and not paid due to the existence of pending registration issues for which the shareholders are responsible with the custodian bank for the shares and with Petrobras, according to note 32.

l) Obligations arising from the acquisition of equity interests in Araucária Nitrogenados, which will be settled by the end of 2030.

Accounting policy for other assets and liabilities

The accounting recognition of obligations arising from divestment is at present value, using a risk-free discount rate, adjusted to reflect the Company's credit risk, being the best estimate of the disbursement required to settle the present obligation on the statement of financial position date. The obligations are subject to significant changes as activity execution schedules are updated and detailed by buyers.

| 22. | The “Lava Jato (Car Wash) Operation” and its effects on the Company

In the preparation of these consolidated financial statements for the year ended December 31, 2024, the Company considered all the available information relating to the “Lava Jato” Operation, and did not identify any of such information that would affect the adopted calculation methodology and would trigger additional write-offs on the overpayments incorrectly capitalized.

The Company will continue to monitor the investigations and collaborate with the competent authorities. Given the absence of new relevant facts in relation to this operation in recent years, the Company does not expect any material changes to the write-off recognized in 2014 or to the methodology adopted, unless the scenario changes in the future.

During 2024, new leniency and plea agreements entitled the Company to receive funds with respect to compensation for damages, in the amount of R$ 336 (R$ 562 in 2023), accounted for as other income and expenses, and must be added to the amount of R$7,281 recognized in previous periods, totaling R$7,617.

Accounting policy for property, plant and equipment

Property, plant and equipment are stated at acquisition costs or construction costs, which also include the costs directly attributable to bringing the asset into operating condition, as well as, when applicable, the estimated costs of dismantling and removing the fixed asset and restoring the location where the asset is located, deducted from accumulated depreciation and losses due to impairment.

Expenses on major planned maintenance, carried out to restore or maintain the original performance standards of industrial units, maritime production units and ships, are recognized in property, plant and equipment when the campaign period is longer than twelve months and the campaigns are predictable. These expenses are depreciated over the expected period until the next major maintenance. Maintenance expenses that do not meet these requirements are recognized as expenses in the income statement for the year.

Replacement parts and spare parts with a useful life of more than one year and which can only be used in connection with items of property, plant and equipment are recognized and depreciated together with the main asset.

Financial charges on loans directly attributable to the acquisition or construction of assets are capitalized as part of the costs of those assets.

In the case of resources raised without specific destination, used for the purpose of obtaining a qualifying asset, the financial charges are capitalized by the average loan rate in force during the period, applied to the balance of works in progress.

The company ceases to capitalize financial charges on qualifying assets whose development is completed. Generally, interest capitalization is suspended, among other reasons, when qualifying assets do not receive significant investments for a period equal to or greater than 12 months.

Assets directly related to the production of oil and gas in a contracted area, whose useful life is not less than the life of the field (reserve exhaustion time), are depleted using the produced units method, including rights and concessions such as the signature bonus.

71

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

Using the produced units method, the depletion rate is calculated based on the monthly production of the respective producing field in relation to its respective developed proven reserve, except for the signature bonus, whose rate is calculated considering the monthly production volume in relation to the total proven reserves of each producing field in the area to which the signature bonus refers.

Assets depreciated using the straight-line method based on estimated useful lives, which are reviewed annually and shown in note 23.2, are: (i) those directly linked to oil and gas production, whose useful life is shorter than the useful life of the field; (ii) mobile platforms; and (iii) other assets not directly related to oil and gas production. Land is not depreciated.

Right-of-use assets are presented as property, plant and equipment and, according to the useful lives of their respective underlying assets and the characteristics of the lease contracts (term, transfer of the asset or exercise of purchase options), are depreciated using the straight-line method based on the contractual terms.

| 23.4. | Oil and Gas fields operated by Petrobras returned to ANP

During the 2024 financial year, Petrobras decided to return the Cachalote field to the ANP, which had a full loss due to impairment. In 2023, losses due to return totaled R$220, referring to the Atum, Curimã, Espada and Xaréu fields, belonging to the Campos Basin, which had not produced since 2020.

| 23.5. | Capitalization rate used to determine the amount of borrowing costs eligible for capitalization

The capitalization rate used to determine the amount of borrowing costs eligible for capitalization was the weighted average of the borrowing costs applicable to the borrowings that were outstanding during the period, other than borrowings made specifically for the purpose of obtaining a qualifying asset. For the year ended December 31,2024, the capitalization rate was 7.19% p.a. (7% p.a. for the year ended December 31, 2023).

| 24.2. | ANP Bidding Result

Blocks in the Pelotas Basin - 4th Permanent Concession Offering Cycle

On December 13, 2023, Petrobras acquired exploration and production rights for oil and natural gas in 29 blocks in the Pelotas Basin during the 4th Permanent Concession Offering Cycle conducted by ANP, with a signature bonus payment of R$ 116 in 2024. For more information about the contracts signed through partnerships, see note 27.

| 24.3. | Exploration rights returned to the ANP

In 2024, the return of 5 exploratory blocks was approved, resulting in the write-off of the respective assets. These blocks are: ES-M-598 and ES-M-673, located in the Espírito Santo Basin; PAR-T-175, in the Paraná Basin, totaling R$ 109; as well as blocks C-M-657 and C-M-709, located in the Campos Basin, as stated in note 25. In 2023, 8 exploration areas located in the pre-salt area of the Campos Basin were returned to ANP, totaling R$ 2,006 in exploration rights written-off.

For more information see note 26 regarding exploration and evaluation of oil and gas reserves.

Accounting policy for intangible assets

Intangible assets are measured at the acquisition cost, less accumulated amortization and impairment losses.

Internally-generated intangible assets are not capitalized and are expensed as incurred, except for development costs that meet the recognition criteria related to the completion and use of assets, probable future economic benefits, and others.

73

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

When the technical and commercial feasibility of oil and gas production is demonstrated for the first field in an area, the value of the signature bonus is reclassified to property, plant and equipment at their full value. While they are registered in intangible assets, they are not amortized. Other intangible assets with defined useful lives are amortized on a straight-line basis over their estimated useful lives.

If, when defining the technical and commercial feasibility of the first field of a block, there are exploratory activities being carried out in different locations in the block, so that oil and gas volumes can be estimated for other possible reservoirs in the area, then the value of the signature bonus is partially reclassified to PP&E, based on the ratio between the volume of oil and gas expected (oil in place - VOIP) of a specific reservoir and the total volume of oil and gas expected for all possible reservoirs in the area.

If exploratory activities in the remaining areas do not result in technical and commercial viability, the corresponding value of the signature bonus is not written off, but transferred to PP&E and added to the value of the signature bonus related to the location that was previously assessed as technically and commercially viable.

Intangible assets with an indefinite useful life are not amortized but are tested annually for impairment. Their useful lives are reviewed annually.

(1)The net book values ​​and recoverable values ​​presented refer only to assets or CGUs that have suffered losses due to impairment or reversals.
(2) The recoverable amount used to evaluate the test is the value in use, except for assets held for sale or when indicated, for which the recoverable amount used for the test is the fair value.

(3) The recoverable and book values ​​of the table considers, by nature, the losses and reversals calculated individually for each CGU. Thus, there are cases in which reversals of impairment are limited to the amount of losses previously recorded, making the column "(Impairment) reversal" not representing the comparison between the columns "Carrying Amount" and "Recoverable Amount".

In assessing the recoverability of property, plant and equipment and intangible assets, tested individually or grouped in cash-generating units - CGU, the company considered the following projections:

| · | Useful life based on the expected use of the assets or set of assets that make up the CGU, considering the company's maintenance policy;

| · | Assumptions and budgets approved by Management for the period corresponding to the expected life cycle, due to the characteristics of the businesses; and

| · | Discount rates derived from the Company’s post-tax weighted average cost of capital (WACC), adjusted by specific risk-premiums in case of projects postponed for an extended period, or by specific country-risks, in case of assets abroad. The use of post-tax discount rates in determining value in use does not result in different recoverable amounts if pre-tax discount rates had been used.

The estimates of the key assumptions in the cash flow projections to determine the value in use of the CGUs in 2024 were:

Strategic Plan 2025-2029 | 2025 | 2026 | 2027 | 2028 | 2029 | Long Term Average
Average Brent in real terms (US$ barrel) | 83 | 77 | 74 | 71 | 68 | 65
Average exchange rate in real terms - R$ /US$ | 5.00 | 4.92 | 4.87 | 4.83 | 4.79 | 4.64

In 2023, the projections used in the impairment tests were:

Strategic Plan 2024-2028 | 2024 | 2025 | 2026 | 2027 | 2028 | Long Term Average
Average Brent in real terms (US$ barrel) | 80 | 78 | 75 | 73 | 70 | 65
Average exchange rate in real terms - R$ /US$ | 5.05 | 5.04 | 5.03 | 4.98 | 4.90 | 4.65

Post-tax discount rates, excluding inflation, applied in the tests which presented the main impairment losses and reversals for the period were:

Activity | 2024 |  | 2023 |
Producing properties relating to oil and gas activities in Brazil | 7.6% p.a. |  | 7.6% p.a. |
RTM in Brazil – postponed projects | 7.7% p.a. |  | 7.0% p.a. |

In 2024, the main changes in the CGUs (in the E&P segment) were:

75

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

• |  | Extinction of the Carapanaúba field due to its annexation to the Sudoeste de Urucu field (Arara group of fields);

• |  | Extinction of the Cherne group of fields due to the signing of a purchase and sale agreement for the transfer of Petrobras' entire interest;

• |  | Extinction of the Cidade Entre Rios field due to its annexation to the Riacho Ouricuri field;

• |  | Exclusion of the Cachalote field following the approval of its abandonment; and

• |  | Reintegration of the Uruguá and Tambaú fields due to the cancellation of the purchase and sale agreement.

Additional information on key assumptions for impairment testing and on CGU definitions is presented in note 4.2.2 and involve judgments and evaluation by Management based on its business model and management.

Information on the main impairment losses and reversals of property, plant and equipment and intangible assets is presented as follows:

a1) Producing properties in Brazil – 2024

The assessments of assets linked to oil and gas production fields in Brazil resulted in net losses of R$6,882, mainly related to: (i) the CGUs of Roncador (R$2,230) and the Barracuda and Caratinga (R$1,242), mainly due to the review of abandonment expenses, as well as the reduction in platform efficiency and well performance forecasts for the Barracuda and Caratinga Cluster, negatively impacting the fields' production curves; and (ii) Uruguá/Tambaú (R$ 3,032), due to the cancellation of the divestment process and the lack of production curves associated with the Business Plan 2025-2029.

a2) Producing properties in Brazil – 2023

Impairment losses on producing properties in Brazil amount to R$ 10,860, mainly in Roncador field (R$ 9,979), due to the revision of the production curve, in the Strategic Plan 2024-2028, arising from below-expected performance of its wells observed in 2023, due to the interruption of production in some wells and to the accelerated decline of production due to the increase in the percentage of water in other wells.

b1) Second refining unit of RNEST – 2024

Losses due to depreciation in the amount of R$2,564, due to the increase in investment estimates and operating expenses, associated to the Business Plan 2025-2029.

b2) Second refining unit of RNEST – 2023

Losses due to depreciation in the amount of R$2,363, mainly due to: (i) reassessment of the RNEST Project, with review of the scope of the logistics infrastructure project, impacting the increase in investments required for the implementation of the 2nd Train; and (ii) review of the premises of Strategic Plan 24-28, resulting in an increase in operating costs.

c1) Oil and gas exploratory assets -2024

The assessments conducted on exploratory assets indicated a reduction in the recoverable values of the exploratory blocks C-M-657 and C-M-709, located in the Campos Basin, and, consequently, the recognition of losses amounting to R$ 1,241. Management approved the full and voluntary relinquishment of these blocks to ANP in October 2024.

c2) Oil and gas exploratory assets - 2023

Reduction in the recoverable values ​​of assets related to blocks C-M-210, C-M-277, C-M-344, C-M-346, C-M-411 and C-M-413, located in the pre-salt layer of the Campos Basin, due to the uneconomic nature of the projects designed for the purpose of eventual development of production, resulting in the recognition of losses of R$1,796. Subsequently, Management approved the full and voluntary return of these blocks to the ANP.

| 25.1.1. | Assets most sensitive to future impairment

The amount of loss due to impairment is based on the difference between the carrying value of the asset or CGU and its respective recoverable value. In our sensitivity analyses, we observed that variations in recoverable values ​​of up to 10%, positive or negative, could potentially represent relevant effects on some specific assets or CGUs, as they would be more susceptible to the recognition of losses or reversals due to impairment in the future, considering significant changes in the assumptions that underpin the assessment.

76

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

The following tables contain information about: (a) assets or CGUs with potential for additional impairment losses in the event of a negative variation of 10% of recoverable values; and (b) assets or CGUs with the potential for impairment reversal in the event of a positive variation of 10% of their recoverable values.

(a) Sensitivity - 10% reduction in the recoverable amount | Business segment | Carrying amount | Recoverable amount (1) | Sensitivity

(1) The recoverable amount was sensitized with -10% and +10% considering the estimated recoverable amounts on 12/31/2024.
(2) The sensitivity determined, when there is a positive variation of 10% in the recoverable amounts, considers the impairment amount to be reversed within the limit of the accumulated impairment balance of the impacted CGUs or within the limit of their recoverable amounts, whichever is lower.

Property, plant and equipment and intangible assets are assessed for impairment at the smallest identifiable group that generates largely independent cash inflows from other assets or groups of assets (CGU). Note 4.2.2 presents detailed information about the Company’s CGUs.

Assets related to development and production of oil and gas assets (fields or clusters) that have indefinite useful lives, such as goodwill, are tested for impairment at least annually, irrespective of whether there is any indication of impairment.

Considering the existing synergies between the Company’s assets and businesses, as well as the expectation of the use of its assets for their remaining useful lives, value in use is generally used by the Company for impairment testing purposes. When specifically indicated, the Company assesses differences between its assumptions and assumptions that would be used by market participants in the determination of the fair value of an asset or CGU.

Reversal of previously recognized impairment losses may occur for assets other than goodwill.

(1) The net book values ​​and recoverable values ​​presented refer only to assets or group of assets that suffered impairment losses or reversals.
(2) The recoverable amount used to evaluate the test is fair value.

In 2024, the Company recognized impairment losses on assets held for sale arising from the assessment at the fair value of assets, net of disposal expenses, mainly arising from Pescada group of fields, due to decommissioning cost review.

In 2023, the Company recognized reversals on assets held for sale in the amount of R$ 506, arising from the assessment at the fair value of assets, net of disposal expenses, mainly arising from the approval for the disposal of Uruguá group of fields.

The accounting practice applied to assets and liabilities classified as held for sale is described in note 29.

| 25.3. | Investments in associates and joint ventures (including goodwill)

Value in use is generally used for impairment test of investments in associates and joint ventures (including goodwill). The basis for estimates of cash flow projections includes: (i) projections covering a period of 5 to 12 years, zero-growth rate perpetuity; (ii) budgets, forecasts and assumptions approved by management; and (iii) a post-tax discount rate derived from the WACC or the Capital Asset Pricing Model (CAPM) models, specific for each case.

Accounting policy for impairment of associates and joint ventures

Investments in associates and joint ventures are tested individually for impairment. When performing impairment testing of an equity-accounted investment, goodwill, if it exists, is also considered part of the carrying amount to be compared to the recoverable amount.

Except when specifically indicated, value in use is generally used by the Company for impairment testing purposes in proportion to the Company’s interests in the present value of future cash flow projections via dividends and other distributions.

| 25.3.1. | Investment in publicly traded associates

Braskem S.A.

Braskem’s shares are publicly traded on stock exchanges in Brazil and abroad. As of December 31, 2024, the quoted market value of the Company’s investment in Braskem was R$ 3,448 based on the quoted values of both Petrobras’ interest in Braskem’s common stock (47% of the outstanding shares), and preferred stock (22% of the outstanding shares), see note 28.4. However, there is extremely limited trading of the common shares, since non-signatories of the shareholders’ agreement hold only approximately 3% of the common shares.

Given the operational relationship between Petrobras and Braskem, the recoverable amount of the investment for impairment testing purposes was determined based on value in use, considering future cash flow projections and the manner in which the Company can derive value from this investment via dividends and other distributions to arrive at its value in use. As the recoverable amount was higher than the carrying amount, no impairment losses were recognized for this investment.

Cash flow projections to determine the value in use of Braskem were based on estimated prices of feedstock and petrochemical products reflecting international trends on prices, petrochemical products sales volume estimates reflecting projected Brazilian and global G.D.P. growth, post-tax discount rate (excluding inflation) of 7.4% p.a., (WACC), and decreases in the EBITDA margin during the growth cycle of the petrochemical industry in the next years and increases in the long-term. Estimated exchange rates and Brent prices are the same as those set out in note 25.1.

| 26. | Exploration and evaluation of oil and gas reserves

These activities cover the search for oil and natural gas reserves from obtaining legal rights to explore a specific area until the moment when the technical and commercial viability of oil and gas production is demonstrated.

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

The recognition of losses in Intangible Assets (R$1,239) and Property, Plant and Equipment (R$2) in 2024 resulted from the assessment of the uneconomic nature of exploration blocks C-M-657 and C-M-709, located in the Campos Basin, given the conclusion that the respective projects would not be developed (as per note 25).

In 2023, losses were recognized in intangible assets in the amount of R$ 1,796, due to the assessment of the unfeasibility of projects of Blocks C-M-210, C-M-277, C-M-344, C-M -346, C-M-411 and C-M-413, situated at the pre-salt of Campos Basin. Subsequently, the company returned these blocks in full and voluntarily to the ANP, in addition to the returns of the Dois Irmãos (R$ 180) and Três Marias (R$ 30) blocks. All blocks are located at the pre-salt in the Campos Basin and the corresponding assets have been written off.

The transfers occurred in Property, Plant and Equipment in 2023 were intended for production development projects in the Raia Pintada and Raia Manta fields, related to block BM-C-33 (R$ 4,685), and the Sépia field (R$ 223).

Exploration costs recognized in the statement of income and cash used in oil and gas exploration and evaluation activities are set out in the following table:

| Consolidated
| 2024 | 2023
Exploration costs recognized in the statement of income |  |
Geological and geophysical expenses | (2,235) | (2,826)

Total cash used | 5,453 | 6,188

(1) Includes values ​​relating to the assessment of the non-economic viability of exploration blocks (note 25).

In 2023 and 2022, Petrobras signed, with the ANP, a Term of Conduct Adjustment (TAC) to offset local content fines related to 24 concessions in which Petrobras has a 100% interest and 22 concessions in which Petrobras operates in partnership with other concessionaires.

The TAC converted fines into E&P investment commitments with local content, resulting in the termination of administrative proceedings and the reversal of liabilities in the amount of R$1 in 2024 (R$266 in 2023).

On December 31, 2024, under these agreements, Petrobras is committed to invest R$990 in local content by December 31, 2027.

Accounting policy for exploration and evaluation of oil and gas reserves

The costs incurred in connection with the exploration, appraisal and development of crude oil and natural gas production are accounted for using the successful efforts method of accounting, as set out below:

| · | geological and geophysical costs related to exploration and appraisal activities incurred until economic and technical feasibility are demonstrated are immediately recognized as an expense;

| · | amounts paid for obtaining concessions for exploration of crude oil and natural gas (capitalized acquisition costs) are initially capitalized as intangible assets and are transferred to property, plant and equipment once the technical and commercial feasibility are demonstrated. More information on intangible assets accounting policy, see note 24;

| · | costs directly attributable to exploratory wells, including their equipment, installations and other costs necessary to identify the technical and commercial feasibility, pending determination of proved reserves, are capitalized within property, plant and equipment. In some cases, exploratory wells have discovered oil and gas reserves, but at the moment the well drilling is completed they are not yet able to be classified as proved. In such cases, the expenses continue to be capitalized if the well has found a sufficient quantity of reserves to justify its completion as a producing well and progress on assessing the reserves and the technical and commercial feasibility of the project is under way (for more information see note 26.1);

| · | an internal commission of technical executives of the Company reviews monthly these conditions for each well, by analysis of geoscience and engineering data, existing economic conditions, operating methods and government regulations (for more information see note 4.1);

79

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

| · | costs related to exploratory wells drilled in areas of unproved reserves are charged to expense when determined to be dry or uneconomic by the aforementioned internal commission; and

| · | costs related to the construction, installation and completion of infrastructure facilities, such as drilling of development wells, construction of platforms and natural gas processing units, construction of equipment and facilities for the extraction, handling, storing, processing or treating crude oil and natural gas, pipelines, storage facilities, waste disposal facilities and other related costs incurred in connection with the development of proved reserve areas (technically and commercially feasible) are capitalized within property, plant and equipment.

| 26.1. | Aging of Capitalized Exploratory Well Costs

The table below shows the costs and the number of exploratory wells capitalized by time of existence, considering the completion date of the drilling activities. It also demonstrates the number of projects for which the costs of exploratory wells have been capitalized for more than one year:

Aging of capitalized exploratory well costs (1) | 2024 | 2023
Exploratory well costs capitalized for a period of one year | 1,923 | 1,021
Exploratory well costs capitalized for a period greater than one year | 7,208 | 6,300
Total capitalized exploratory well costs | 9,131 | 7,321
Number of projects relating to exploratory well costs capitalized for a period greater than one year | 18 | 17
Exploratory well costs capitalized for a period greater than one year | 2024 | Number of wells
2023 | 470 | 2
2022 | 1,295 | 3
2021 | 451 | 2
2020 | 104 | 1
2019 and previous years | 4,888 | 14
Total | 7,208 | 22
(1) Amounts paid for obtaining rights and concessions for exploration of oil and gas (capitalized acquisition costs) are not included.

Of the total of R$7,208 for 18 projects, which include 22 wells in progress for more than one year since the completion of drilling activities, R$6,476 refer to wells located in areas where drilling activities are already in progress or firmly planned for the near future, whose "Assessment Plan" was submitted for approval by the ANP, and R$ 352 refer to activities inherent in the process of analyzing the technical and economic viability for the decision on the possible development of production of the projects and definition of proved reserves.

| 26.2. | Collateral for crude oil exploration concession agreements

The Company has granted collateral to ANP in connection with the performance of the Minimum Exploration Programs established in the concession agreements for petroleum exploration areas in the total amount of R$ 7,740 (R$ 8,568 as of December 31, 2023), which is still in force as of December 31, 2024, net of commitments undertaken. As of December 31, 2024, the collateral comprises future crude oil production capacity from Marlim and Buzios producing fields, already in production, pledged as collateral, in the amount of R$ 7,669 (R$ 8,502 as of December 31, 2023) and bank guarantees of R$ 71 (R$ 66 as of December 31, 2023).

| 27. | Consortia (partnerships) in E&P activities

In line with its strategic objectives, Petrobras operates in association with other companies in consortia as holder of oil and natural gas exploration and production rights in concessions and production sharing regimes.

As of December 31, 2024, the company has an interest in 95 consortia with 34 partner companies, of which Petrobras is the operator in 64 consortia (67 consortia, 32 partner companies, being the operator in 39 consortia, in 2023). The increase of 28 was due to the creation of 32 new consortia, offset by 2 returns and 2 partnerships that became 100% Petrobras.

The partnerships established in 2024, with Petrobras as the operator, are related to the 4th Cycle of the Permanent Concession Offer in the Pelotas Basin, as follows:

• |  | 26 contracts with Petrobras holding a 70% stake and Shell holding 30%; and

• |  | 3 contracts with Petrobras holding a 50% stake, Shell 30%, and CNOOC 20% (more information about the signature bonus is in note 24.2).

Additionally, Petrobras will act as a non-operator in 3 new partnerships in São Tomé and Príncipe.

In 2023, 2 new partnerships were formed with Petrobras as the operator, both related to the 1st Cycle of the Permanent Sharing Offer:

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

• |  | Campos Basin, with 30% held by Petrobras, 30% by TotalEnergies, 20% by Petronas, and 20% by Qatar Energy; and

• |  | Santos Basin, with Petrobras holding a 60% stake and Shell 40%.

Consortia bring benefits through risk sharing, increased investment capacity, technical and technological interchange, aiming at the growth in oil and gas production. The following table presents the production referring to Petrobras's participation in the main fields in which the Company is the operator in the consortium:

Field | Location | Petrobras interest | Partners interest | Petrobras production portion in 2024 (mboed) | Regime

Accounting policy for joint operations

The E&P consortia are classified as joint operations, where the assets, liabilities, revenues and expenses relating to these consortia are accounted for in the financial statements individually, observing the applicable specific accounting policies and reflecting the portion of the contractual rights and obligations that the Company has.

| 27.1. | Unitization Agreements

Petrobras has Production Individualization Agreements (AIP) signed in Brazil with partner companies in E&P consortia. These agreements result in reimbursements payable to (or receivable from) partners regarding expenses and production volumes mainly related to Agulhinha, Albacora Leste, Berbigão, Budião Noroeste, Budião Sudeste, Caratinga and Sururu.

Provision for equalizations (1)

The table below presents changes in the reimbursements payable relating to the execution of the AIP submitted to the approval of the ANP:

| Consolidated and Parent Company
| 2024 | 2023
Opening balance | 2,238 | 2,122
Additions/(Write-offs) on PP&E | 1,265 | 80
Translation adjustments | − | 2
Payments made | (6) | (277)
Other income and expenses | 78 | 311
Closing balance | 3,575 | 2,238
(1)Mainly Berbigão, Sururu and Agulhinha.

81

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

The change in the year reflects the best available estimate of the assumptions used in the calculation base and the sharing of assets in areas to be equalized.

Closed agreements in 2024

In May 2024, the Agreement on Expenditure and Volume Equalization, provided for in the Brava Shared Reservoir AIP, was signed. The amount paid by Petrobras to Pré-sal Petróleo S.A. (PPSA) on June 24, 2024 was R$6.

Accounting Policy for unitization agreements

A unitization agreement occurs when a reservoir extends across two or more license or contract areas. In this case, partners pool their individual interests in return for an interest in the overall unit (shared reservoir) and determine their new stake in the single producing unit.

Events that occurred prior to the unitization agreement may lead to the need for compensation between the partners. The compensation will be the difference between the expenses actually incurred by each party up to the reference date and those that should have been incurred by each party if the established participations in the shared reservoir by the AIP were already in effect during that period.

At the signing of the AIP, an amount to be reimbursed to the Company will be recognized as an asset only when there is a contractual right to reimbursement or when the reimbursement is practically certain. An amount to be reimbursed by the Company will be recognized as a liability when it derives from a contractual obligation or, when the outflow of funds is deemed probable and the amount can be reliable estimated. The provision will be offset by an increase or decrease in PP&E, revenues and/or expenses, according to the nature of the events to be reimbursed.

Accounting policy for investments

Basis of consolidation

The consolidated financial statements include the financial information of Petrobras and the entities it controls (subsidiaries), joint operations (at the level of interest the Company has in them) and consolidated structured entities.

Intragroup balances and transactions, including unrealized profits arising from intragroup transactions, are eliminated in the consolidation of the financial statements.

Investments in other companies

In the individual financial statements, investments in subsidiaries, associates, joint ventures and non-profit associations are accounted for by the equity method. In joint operations, only those established through a vehicle entity with its own legal personality are accounted for by the equity method. For other joint operations, the company recognizes its assets and liabilities, as well as its respective revenues and expenses.

In the consolidated financial statements, investments in associates and jointly controlled ventures are accounted for by the equity method.

Business combination

A business combination is a transaction in which the acquirer obtains control of another business, regardless it legal form. Acquisitions of businesses are accounted for using the acquisition method when control is obtained. Combinations of entities under common control are accounted for at cost. The acquisition method requires that the identifiable assets acquired and the liabilities assumed be measured at the acquisition-date fair value, with limited exceptions.

| 29. | Disposal of assets and other transactions

The major classes of assets and related liabilities classified as held for sale are shown in the following table:

| 29.1. | Sales pending closing at December 31, 2024

| a) | Cherne and Bagre fields

On April 25, 2024, the Company signed an agreement with Perenco Pétroleo e Gás Ltda (“Perenco”) for the sale of its entire interest in the Cherne and Bagre fields, located in shallow waters of the Santos Basin.

The amount to be received is US$ 10 million, of which R$ 5 (US$ 1 million) was received at the transaction signing and the remainder will be received on the closing date.

| 29.2. | Transaction interrupted

| a) | Uruguá and Tambaú fields

On December 21, 2023, the Company signed agreements with Enauta Energia S.A. for the sale of its entire interest in the Uruguá and Tambaú fields located in the post-salt layer of the Santos basin.

On December 21, 2024, due to the non-completion of the acquisition of the FPSO Cidade de Santos by Enauta, Petrobras notified Brava Energia S.A. (Enauta's parent company) of its decision to terminate the agreement, since the closing of the transaction was subject, among other factors, to the completion of the FPSO acquisition, as provided for in the contract.

The closing of the transaction was conditioned, among other factors, to the completion of the acquisition of the FPSO. The amount of R$ 15 (US$ 3 million) was received in advance on the signing date and was retained by Petrobras, as also provided for in the contract, and recognized as other income and expenses, net.

Petrobras maintains its 100% interest on the Uruguá and Tambaú fields and is assessing the alternatives for the management of these assets, which were classified as property, plant and equipment on December 31, 2024.

Accounting Policy for assets and liabilities held for sale

Non-current assets, disposal groups and liabilities directly associated with those assets are classified as held for sale if their carrying amounts will be recovered mainly through a sale transaction.

The condition for classification as held for sale is met only when the sale is approved by the Company’s Board of Directors and the asset or disposal group is available for immediate sale in its present condition and there is the expectation that the sale will occur within 12 months after its classification as held for sale. However, an extended period required to complete a sale does not preclude an asset (or disposal group) from being classified as held for sale if the delay is caused by events or circumstances beyond the Company’s control and there is sufficient evidence that the Company remains committed to its plan to sell the assets (or disposal groups).

Assets (or disposal groups) classified as held for sale and the associated liabilities are measured at the lower of their carrying amount and fair value less disposal expenses.

In the classification of non-current assets as held for sale, provisions for decommissioning costs related to these assets are also disclosed. Any commitments with decommissioning assumed by the Company resulting from the sale process are recognized after the closing of the transaction, in accordance with the contractual terms.

Sépia and Atapu

In 2022, Petrobras signed Production Individualization Agreements (AIPs) for Atapu and Sépia fields, according to the results of the Second Bidding Round for the Surplus Volume of the Transfer of Rights Agreement in the Production Sharing regime. Petrobras explores the Sépia field in a consortium with TotalEnergies EP Brasil Ltda. (28% interest), Petronas Petróleo Brasil Ltda. (21% interest) and QP Brasil Ltda. (21% interest), while the Atapu field is explored in a consortium with Shell Brasil Petróleo Ltda (25% interest) and TotalEnergies EP Brasil Ltda. (22.5% interest).

In addition to the amounts received by Petrobras in previous years following the signing of the AIPs, as established in Ordinance No. 8/2021, whenever the price of Brent oil reaches an annual average ranging from US$ 40.00 to US$ 70.00, an earnout is due to Petrobras, for which the Company expects to receive a maximum of US$ 5,244 million between 2022 and 2032.

In 2024, the Company recognized R$1,529 (US$262 million) in assets, of which: i) R$996 (US$161 million) related to the 2025 earnout, expected to be received in 2026; and ii) R$533 (US$101 million) for the update of the 2024 earnout, received in January 2025. In previous years, the total amount of R$4,854 (US$948 million) was recognized in assets, of which R$1,235 was in 2023.

On December 31, 2024, the fair value of the Company's finance debt is mainly determined and categorized into a fair value hierarchy as follows:

• |  | Level 1- quoted prices in active markets for identical liabilities, when applicable, amounting to R$ 69,193 of December 31, 2024 (R$ 67,639 of December 31, 2023); and

• |  | Level 2 – discounted cash flows based on discount rate determined by interpolating spot rates considering financing debts indexes proxies, taking into account their currencies and also Petrobras’ credit risk, amounting to R$ 68,356 as of December 31, 2024 (R$ 74,348 as of December 31, 2023).

Regarding the Interest Rate Benchmark Reform (IBOR Reform), there was a necessity to amend the Company's contracts referenced in these indexes, considering the end of the publication of LIBOR (London Interbank Offered Rate) in dollars (US$), of one, three and six months.

As of December 31, 2024, approximately 18% of the Company's finance debt has been indexed to SOFR (Secured Overnight Financing Rate) and has the CSA (Credit Spread Adjustment) negotiated with the creditors serving as a parameter.

The totality of the renegotiations performed have been solely for the replacement of the LIBOR benchmark and were necessary as a direct consequence of the reform of the reference interest rate. In these renegotiated cash flows, the change of the index was economically equivalent to the previous basis. Thus, the changes were prospective with the recognition of interest at the new index in the applicable periods.

| 30.6. | Covenants and Collateral

| 30.6.1. | Covenants

The Company has covenants that were not in default at December 31, 2024 in its loan agreements and notes issued in the capital markets requiring, among other obligations: i) the presentation of interim financial statements within 90 days of the end of each quarter (not reviewed by Independent Registered Public Accounting Firm) and audited financial statements within 120 days of the end of each fiscal year; (ii) Negative Pledge/Permitted Liens clause, where Petrobras and its material subsidiaries undertake not to create liens on their assets to guarantee debts beyond those permitted; (iii) clauses complying with laws, rules and regulations applicable to the conduct of its business, including (but not limited to) environmental laws; (iv) clauses in financing contracts that require both the borrower and the guarantor to conduct their business in compliance with anti-corruption laws and anti-money laundering laws and to establish and maintain policies necessary for such compliance; (v) clauses in financing contracts that restrict relationships with entities or even countries sanctioned primarily by the United States, including, but not limited to, the Office of Foreign Assets Control – OFAC, Department of State and Department of Commerce, the European Union and the United Nations.

If the Company breaches any of the aforementioned covenants and either is incapable of remedy or continues to fail to comply with the covenants for a period ranging from 30 to 60 calendar days (depending on the contract) after it has received a written notice from the creditors specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default”, this may be declared an Event of Default, and in certain cases the debt related to that contract becomes due and payable.

| 30.6.2. | Collateral

Financial institutions normally do not require guarantees for loans and financing granted to Petrobras. However, there is financing granted through specific instruments, which have real guarantees. Such contracts represent 11.9% of total financing, with emphasis on the contract obtained from the China Development Bank (CDB), according to note 34.6.

Loans obtained by structured entities are guaranteed by the projects themselves, as well as by pledges of credit rights.

91

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

Financing from the capital market, which corresponds to securities issued by the company, does not have real guarantees.

Accounting policy for loans and finance debt

Loans and finance debt are initially recognized at fair value less transaction costs that are directly attributable to its issue and subsequently measured at amortized cost using the effective interest method.

When the contractual cash flows of a financial liability measured at amortized cost are renegotiated or modified and this change is not substantial, its gross carrying amount will reflect the discounted present value of its cash flows under new terms using the original effective interest rate. The difference between the book value immediately prior to such modification and the new gross carrying amount is recognized as gain or loss in the statement of income. When such modification is substantial, the original liability is extinguished and a new liability is recognized, impacting the statement of income of the period.

The sensitivity analysis of financial instruments subject to exchange variation is presented in note 33.4.1.

Accounting policy for lease liabilities

Lease liabilities, including those whose underlying assets are of low value, are measured at the present value of lease payments, which includes recoverable taxes, non-cancellable periods and options to extend a lease when they are reasonably certain.

93

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

These payments are discounted at the Company's nominal incremental rate on loans, as the interest rates implicit in lease agreements with third parties usually cannot be readily determined.

Lease remeasurements reflect changes arising from contractual rates or indexes, as well as lease terms due to new expectations of lease extensions or terminations.

Unwinding of discount on the lease liability is classified as finance expense, while payments reduce their carrying amount. According to the Company’s foreign exchange risk management, foreign exchange variations on lease liabilities denominated in U.S. dollars are designated as instruments to protect cash flow hedge relationships from highly probable future exports (see note 35.2.2).

In the E&P segment, some activities are conducted by joint operations with partner companies where the Company is the operator. In cases where all parties to the joint operation are primarily responsible for the lease payments, the Company recognizes the lease liability in proportion to its share. When using underlying assets arising from a specific contract in which the Company is solely responsible for the lease payments, the lease liabilities remain fully recognized and the partners are charged in proportion to their interests.

Payments associated with short-term leases (term of 12 months or less) are recognized as an expense over the term of the lease.

Legal reserve

It represents the accumulated balance of 5% of the net income for each year, calculated pursuant to article 193 of the Brazilian Corporation Law, limited to 20% of the share capital. The reserve may only be used to offset losses or increase capital. The balance of this reserve reached the legal limit on December 31, 2023.

Statutory reserves

In accordance with the Company's Bylaws, the constitution of the statutory reserves below must be considered in the proposal for distribution of net income, observing the following order of priority:

| · | Reserve for research and development (R&D): constituted with the appropriation of net income by applying 0.5% of the year-end share capital, with the accumulated balance not exceeding 5% of the share capital, aiming at funding technological R&D programs. The balance of this reserve reached the limit on December 31, 2023.

| · | Capital remuneration reserve: may be constituted through the appropriation of up to 70% of the adjusted net income for the year, subject to article 202 of the Brazilian Corporation Law and to the Shareholders Remuneration Policy, limited to the share capital, with the purpose of ensuring resources for the payment of dividends, interest on capital or other form of shareholder remuneration provided for by law, its anticipations, shares repurchases authorized by law, absorption of losses and, as a remaining purpose, incorporation into the share capital.

95

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

Tax incentives reserve

Government grants are recognized in the statement of income and are appropriated from retained earnings to the tax incentive reserve pursuant to article 195-A of Brazilian Corporation Law. This reserve may only be used to offset losses or increase share capital.

As of December 31, 2024, this reserve referring to a subsidy incentive for investments, granted by the Superintendencies for Development of the Northeast Region of Brazil (SUDENE) and of the Amazon (SUDAM).

Profit retention reserve

It includes funds intended for capital expenditures, primarily in oil and gas exploration and development activities, as per the capital budget of the Company, pursuant to article 196 of the Brazilian Corporation Law.

32.4.2. Distributions to shareholders

Distributions to shareholders are made by means of dividends, interest capital and share repurchases based on the limits defined in the Brazilian Corporation Law, in the Company’s bylaws and in the shareholders remuneration policy.

Pursuant to Brazilian Corporation Law, the Company’s shareholders are entitled to receive minimum mandatory dividends (and/or interest on capital) of 25% of the adjusted net income for the year in proportion to the number of common and preferred shares held by them.

To the extent the Company proposes dividend distributions, preferred shares have priority in dividend distribution, which is based on the highest of 3% of the preferred shares’ net book value or 5% of the preferred share capital. Preferred shares participate under the same terms as common shares in capital increases resulting from the capitalization of profit reserves or retained earnings. However, this priority does not necessarily grant dividend distributions to the preferred shareholders in the event of loss for a year.

The payment of dividends may be made only to preferred shareholders if the priority dividends absorb all the adjusted net income for the year or reach an amount equal to or greater than the mandatory minimum dividend of 25%.

| a) | Shareholders Remuneration Policy

The Company’s policy on distributions to shareholders, approved by the Company’s Board of Directors on July 28, 2023, defines the following:

| · | minimum distribution of US$ 4 billion for fiscal years when the average Brent price exceeds US$ 40 per barrel, which shall be distributed regardless of its level of indebtedness, provided that the parameters set forth in the policy are observed. This distribution will be equal to both common and preferred shares, once it exceeds the minimum value for preferred shares provided for in the Company's bylaws;

| · | in the event of gross debt equal to or less than the maximum debt level defined in the strategic plan (US$ 75 billion in the 2025-2029 Business Plan), in addition to the existence of net income attributable to shareholders of Petrobras, to be verified at the end of the year and approved by the Board of Directors, the Company shall distribute to its shareholders 45% of the free cash flow, which is the difference between consolidated net cash provided by operating activities and consolidated cash used in the acquisition of PP&E and intangible assets and on the acquisition of equity interests, calculated in Brazilian reais, provided that the result of this calculation exceeds US$ 4 billion and does not compromise the financial sustainability of the Company. This calculation will be applied on a quarterly basis;

| · | any amounts related to share repurchases, as disclosed in the consolidated statement of cash flows, are be deducted from the amount resulting of the formula applied each quarter;

| · | the Company may, in exceptional cases, distribute extraordinary remuneration to its shareholders, higher than the minimum mandatory dividends or than the amount calculated according to this policy, provided that the financial sustainability of the Company is preserved;

| · | the distribution of remuneration to shareholders shall be made on a quarterly basis;

| · | the Company may exceptionally distribute dividends even if there is no net income for the year, in accordance with the rules provided for the Brazilian Corporation Law and the criteria defined in this policy.

96

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

Petrobras seeks, through its shareholders remuneration policy, to ensure short, medium and long-term financial sustainability, providing predictability to the dividend payments to shareholders. Then, the payment of remuneration to shareholders must not compromise the company's short, medium and long-term financial sustainability.

32.4.3. Unclaimed Dividends

As of December 31, 2024, the balance of dividends not claimed by shareholders of Petrobras is R$ 1,708 (R$ 1,630 on December 31, 2023), recorded as other current liabilities, as described in note 21. The payment of these dividends was not carried out due to the lack of registration data for which the shareholders are responsible with the custodian bank for the Company's shares.

Accounting policy on distributions to shareholders

Interest on capital is a deductible expense, since it is part of the dividend for the year, as provided for in the Company’s bylaws, and accounted for in the statement of income, as required by tax legislation, resulting in a tax credit for income taxes recognized in the statement of income of the year.

The dividends portion provided for in the bylaws or that represents the minimum mandatory dividends is recognized as a liability within the statement of financial position. Any excess must be maintained in shareholders' equity, as additional dividends proposed, until its approval on the Annual General Shareholders Meeting.

Dividends not claimed by Petrobras’ shareholders are transferred from dividends payable to other current liabilities. After 3 years from the date these dividends are made available to shareholders, they are reclassified from other current liabilities to equity within retained earnings, in accordance with Petrobras' bylaws.

Basic earnings per share are calculated by dividing the net income (loss) attributable to shareholders of Petrobras by the weighted average number of outstanding shares during the period. The change in the weighted average number of outstanding shares is due to the share repurchase program (preferred shares) which was closed on August 4, 2024.

Diluted earnings per share are calculated by adjusting the net income (loss) attributable to shareholders of Petrobras and the weighted average number of outstanding shares during the period taking into account the effects of all dilutive potential shares (equity instrument or contractual arrangements that are convertible into shares).

Basic and diluted earnings are identical as the Company has no potentially dilutive shares.

| 33. | Risk management

Petrobras is exposed to a series of risks arising from its operations, such as the risk related to the prices of oil and oil products, exchange and interest rates, credit and liquidity risk. Corporate risk management is part of the company's commitment to act ethically and in compliance with the legal and regulatory requirements established in the countries where it operates.

For the management of market / financial risks, preferably structural actions are adopted, created as a result of an adequate management of the company's capital and indebtedness. Risks are managed considering governance and established controls, specialized units and monitoring in statutory committees under the guidance of the Executive Board and the Board of Directors. In the company, risks must be considered in all decisions and their management must be carried out in an integrated manner, taking advantage of the benefits of diversification.

In its corporate risk management process, Petrobras maintains derivative financial instruments to hedge its exposures to market risks on certain occasions and designates certain U.S. dollar obligations and highly probable future exports as hedge accounting relationships to protect against exchange rate variations.

The Company presents a sensitivity analysis for the period of one year, except for operations with commodity derivatives, for which a three-month period is applied, due to the short-term nature of these transactions.

The effects of derivative financial instruments and hedge accounting are set out as follows.

| 33.4. | Market risks

| 33.4.1. | Foreign exchange risk management

By managing its foreign exchange risk, the Company takes into account the cash flows derived from its operations as a whole. This concept is especially applicable to the risk relating to the exposure of the Brazilian Real against the U.S. dollar, in which future cash flows in U.S. dollar, as well as cash flows in Brazilian Real affected by the fluctuation between both currencies, such as cash flows derived from diesel and gasoline sales in the domestic market, are assessed in an integrated manner.

Accordingly, the financial risk management mainly involves structured actions encompassing the business of the Company.

Changes in the Real/U.S. dollar spot rate, as well as foreign exchange variation of the Real against other foreign currencies, may affect net income and the statement of financial position due to the exposures in foreign currencies, such as high probable future transactions, monetary items and firm commitments.

The Company seeks to mitigate the effect of potential variations in the Real/U.S. dollar spot rates mainly raising funds denominated in U.S. dollars, aiming at reducing the net exposure between obligations and receipts in this currency, thus representing a form of structural protection that takes into account criteria of liquidity and cost competitiveness.

Foreign exchange variation on future exports denominated in U.S. Dollar in a given period are efficiently hedged by the U.S. dollar debt portfolio taking into account changes in such portfolio over time. Cash flow hedge involving the Company’s future exports are presented in note 33.4.1(a).

The foreign exchange risk management strategy may involve the use of derivative financial instruments to hedge certain liabilities, mitigating foreign exchange rate risk exposure, especially when the Company is exposed to a foreign currency in which no cash inflows are expected. The positions with exchange rate derivatives are presented in note 33.3.

In the short-term, the foreign exchange risk is managed by applying resources in cash or cash equivalent denominated in Brazilian Real, U.S. dollar or in another currency.

a)Cash Flow Hedge involving the Company’s future exports

The Company uses hedge accounting for the risk arising from exchange rate variations of “highly probable future exports” (hedged item) by means of foreign exchange rate variations of proportions of certain obligations denominated in U.S. dollars (hedging instruments).

The carrying amounts, the fair value as of December 31, 2024, and a schedule of expected reclassifications to the statement of income of cumulative losses recognized in other comprehensive income (shareholders’ equity) based on a US$ 1.00 / R$ 6.1923 exchange rate are set out below:

.

In the year ended on December 31, 2024, a foreign exchange loss of R$ 1,154 was recognized referring to the ineffectiveness in the exchange variation line (gain of R$ 829 in the same period in 2023).

Future exports designated as hedged in cash flow hedge relationships represent, on average, 69.11% of highly probable future exports.

A roll-forward schedule of cumulative foreign exchange losses recognized in shareholders’ equity to be realized by future exports is set out below:

| 2024 | 2023
Opening balance | (28,833) | (70,089)

Other comprehensive income (loss) | (69,261) | 41,256
Closing balance | (98,094) | (28,833)

Additional hedging relationships may be revoked or additional reclassification adjustments from equity to the statement of income may occur as a result of changes in forecasted export prices and export volumes following a revision of the Company’s strategic plan. Based on a sensitivity analysis considering a US$ 10/barrel decrease in Brent prices stress scenario, when compared to the Brent price projections in the Business Plan 2025-2029, would not indicate a reclassification from equity to the statement of income.

A schedule of expected reclassification of cumulative foreign exchange losses recognized in other comprehensive income to the statement of income as of December 31, 2024, is set out below:

| 2025 | 2026 | 2027 | 2028 | 2029 | 2030 onwards | Consolidated Total

Accounting policy for hedge accounting

At inception of the hedge relationship, the Company documents its objective and strategy, including identification of the hedging instrument, the hedged item, the nature of the hedged risk and evaluation of hedge effectiveness requirements.

Considering the natural hedge and the risk management strategy, the Company designates hedging relationships to account for the effects of the existing hedge between a foreign exchange gain or loss from proportions of its long-term debt obligations (denominated in U.S. dollars) and foreign exchange gain or loss of its highly probable U.S. dollar denominated future exports revenues, so that gains or losses associated with the hedged transaction (the highly probable future exports) and the hedging instrument (debt obligations) are recognized in the statement of income in the same periods.

Foreign exchange gains and losses on proportions of debt obligations and lease liability (non-derivative financial instruments) have been designated as hedging instruments.

103

NOTES TO THE FINANCIAL STATEMENTS PETROBRAS (In millions of reais, unless otherwise indicated)

The highly probable future exports for each month are hedged by a proportion of the debt obligations with an equal US dollar nominal amount. Only a portion of the Company’s forecast exports are considered highly probable.

The Company’s future exports are exposed to the risk of variation in the Brazilian Real/U.S. dollar spot rate, which is offset by the converse exposure to the same type of risk with respect to its debt denominated in U.S. dollar.

The hedge relationships are assessed on a monthly basis and they may cease and may be re-designated in order to achieve the risk management strategy.

Foreign exchange gains and losses relating to the effective portion of such hedges are recognized in equity, within other comprehensive income and reclassified to the statement of income within finance income (expense) in the periods when the hedged item affects the statement of income.

Whenever a portion of future exports for a certain period, for which their foreign exchange gains and losses hedging relationship has been designated is no longer highly probable, the Company revokes the designation and the cumulative foreign exchange gains or losses that have been recognized in other comprehensive income remain separately in equity until the forecast exports occur.

If future exports for which foreign exchange gains and losses hedging relationship has been designated is no longer expected to occur, any related cumulative foreign exchange gains or losses that have been recognized in other comprehensive income from the date the hedging relationship was designated to the date the Company revoked the designation is immediately recycled from other comprehensive income to the statement of income.

In addition, when a financial instrument designated as a hedging instrument expires or settles, the Company may replace it with another financial instrument in a manner in which the hedge relationship continues to occur. Likewise, whenever a hedged transaction effectively occurs, its financial instrument previously designated as a hedging instrument may be designated for a new hedge relationship.

Gains or losses relating to the ineffective portion are immediately recognized in finance income (expense). Ineffectiveness may occur as hedged items and hedge instruments have different maturity dates and due to discount rate used to determine their present value.

b)Derivative financial instruments not designated for hedge accounting

In 2019, Petrobras contracted derivative transactions with the objective of protecting itself from exposure arising from the 1st series of the 7th debenture issue, with IPCA x CDI interest rate swap transactions, maturing in September 2029 and September 2034, and CDI x Dollar cross-currency swap transactions, maturing in September 2024 and September 2029. In September 2024, the notional value of the matured cross-currency swap was US$ 241 million.

The methodology used to calculate the fair value of this swap operation consists of calculating the future value of the operations, using rates agreed in each contract and the projections of the interest rate curves, IPCA coupon and foreign exchange coupon, discounting to present value using the risk-free rate. Curves are obtained from Bloomberg based on forward contracts traded in stock exchanges.

The mark-to-market is adjusted to the credit risk of the financial institutions, which is not relevant in terms of financial volume, since the Company makes contracts with highly rated banks.

Changes in interest rate forward curves (CDI interest rate) may affect the Company's results, due to the market value of these swap contracts. In preparing a sensitivity analysis for these curves, a parallel shock was estimated based on the average maturity of these swap contracts, in the scope of the Company’s Risk Management Policy, which resulted in a 618 basis points effect on the estimated interest rate. The effect of this sensitivity analysis, keeping all other variables constant, is shown in the following table:

Financial Instruments | Consolidated Reasonably Possible scenario
SWAP CDI x USD |  | (62)

c) Sensitivity analysis for foreign exchange risk on financial instruments

The sensitivity analysis only covers the exchange rate variation and maintains all other variables constant. The probable scenario is referenced on external sources like Focus bulletin and Thomson Reuters, making use of the exchange rate forecast for the end of the following year, as follows:

· |  | U.S. dollar x real - a 3.15% appreciation of the real;

· |  | Euro x U.S. dollar - a 1.03% depreciation of the euro; and

· |  | Pound sterling x U.S. dollar - a 1.32% depreciation of the pound sterling.

The reasonably possible scenario has the same references and considers a 20% devaluation of the year's closing exchange rate (risk) in relation to the reference currency during the period analyzed, with the exception of the balances of assets and liabilities in foreign currency of subsidiaries abroad, when carried out in currency equivalent to their respective functional currencies.

| 33.4.2. | Risk management of products prices - crude oil and oil products and other commodities

The Company is exposed to commodity price cycles, and it may use derivative instruments to hedge exposures related to prices of products purchased and sold to fulfill operational needs and in specific circumstances depending on business environment analysis and assessment of whether the targets of the Business Plan are being met.

The Company, by use of its assets, positions and market knowledge from its operations in Brazil and abroad, may seek to optimize some of its commercial operations in the international market, with the use of commodity derivatives to manage price risk.

The probable scenario uses market references, used in pricing models for oil, oil products and natural gas markets, and takes into account the closing price of the asset on December 31, 2024. Therefore, no effect is considered arising from outstanding operations in this scenario. The reasonably possible scenario reflects the potential effects on the statement of income from outstanding transactions, considering a variation in the closing price of 20%. To simulate the most unfavorable scenarios, the variation was applied to each asset according to open transactions: price decrease for long positions and increase for short positions.

Crude oil and oil products - price changes | Future and forward contracts (Swap) | − | (918)

The positions with commodity derivatives are presented in note 33.3.

| 33.4.3. | Interest rate risk management

The Company considers that interest rate risk does not create a significant exposure and therefore, preferably does not use derivative financial instruments to manage interest rate risk, except for specific situations faced by certain subsidiaries of Petrobras.

(1) Represents the Secured Overnight Funding Rate (note 24.4).

| 33.5. | Liquidity risk management

The possibility of a shortage of cash to settle the Company’s obligations on the agreed dates is managed by the Company. The Company mitigates its liquidity risk by defining reference parameters for treasury management and by periodically analyzing the risks associated to the projected cash flow, quantifying its main risks through Monte Carlo simulations. These risks include oil prices, exchange rates, gasoline and diesel international prices, among others. In this way, the Company is able to predict cash needs for its operational continuity and for the execution of its strategic plan.

In this context, Petrobras' individual and consolidated financial statements, even though they show negative net working capital, do not compromise its liquidity.

In addition, the company maintains revolving credit facilities contracted as a liquidity reserve in adverse situations, as per note 30.5, and regularly assesses market conditions and may carry out repurchase transactions of its securities or those of its subsidiaries in the international capital market, by various means, including repurchase offers, redemptions of securities and/or open market transactions, provided that they are in line with the company's liability management strategy, which aims to improve the amortization profile and cost of debt.

The expected cash flows from finance debt, lease liabilities, post-employment benefits and decommissioning costs are presented in notes 30.4 and 31, 18.3.4 and 20, respectively.

| 33.6. | Credit risk management

The credit risk management policy aims to minimize the possibility of not receiving sales made and amounts invested, deposited or guaranteed by financial institutions and counterparties, through analysis, granting and management of credits, using quantitative and qualitative parameters appropriate to each one of the market segments in which it operates.

The commercial credit portfolio is quite diversified between clients from the country's domestic market and foreign markets.

Credit granted to financial institutions is used to accept guarantees, apply cash surpluses and define counterparties in derivative operations, being distributed among the main international banks classified as “investment grade” by the main international risk classifiers and Brazilian banks with a minimum risk rating brA-/A3.br/A-(bra).

| 33.6.1. | Credit quality of financial assets

| a) | Cash and cash equivalents and marketable securities

The evaluation of the credit quality of these financial assets is based on external credit ratings provided by Standard & Poor’s, Moody’s and Fitch, as follows:

As of December 31, 2024, the Brazilian sovereign risk is BB, the best level within the speculative grade category, with effect on the rating of Brazilian banks abroad, which represent most of the Company’s balance of other ratings abroad, including cash.

These financial assets, which are not past due nor considered to be credit impaired, present fair values ​​equivalent to or do not differ significantly from their carrying amounts.

| b) | Trade and other receivables

Most of Petrobras's clients do not have a risk rating granted by rating agencies. Thus, for the definition and monitoring of credit limits, management evaluates the customer's field of activity, commercial relationship, financial relationship with Petrobras and its financial statements, among other aspects.

More information on the effect of this risk assessment is available in notes 14.2 and 14.3, which present the provision for expected credit losses and the respective accounting policy.

| 34. | Related-party transactions

The Company has a related-party transactions policy, which is annually revised and approved by the Board of Directors in accordance with the Company’s bylaws.

In order to ensure the goals of the Company are achieved and to align them with transparency of processes and corporate governance best practices, this policy guides Petrobras while entering into related-party transactions and dealing with potential conflicts of interest on these transactions, based on the following assumptions and provisions: competitiveness, compliance, transparency, fairness and commutability.

Transactions that meet the materiality criteria established in the policy and entered into with: i) the Federal Government, including its agencies and foundations; ii) the Petros Foundation; iii) the Petrobras Health Association; iv) companies controlled by Petrobras, if the Federal Government or its Entities or an authority of the public entity to which Petrobras is linked or persons linked to it hold a stake in the capital stock of the subsidiary; v) companies affiliated with Petrobras; vi) companies controlled by Petrobras affiliates and vii) companies controlled by key management personnel or by a close member of their family, are, when stipulated, previously approved by the Statutory Audit Committee (CAE).

Transactions with the Brazilian Federal Government, including its agencies or similar bodies and controlled entities (the latter when classified as out of the Company's normal course of business by the CAE), which are under the scope of Board of Directors approval, must be preceded by the CAE and Minority Shareholders Committee assessment and must have prior approval of, at least, 2/3 of the board members.

The related-party transactions policy also aims to ensure an adequate and diligent decision-making process for the Company’s key management.

SUPPLEMENTARY INFORMATION (Unaudited) PETROBRAS (In millions of reais, unless otherwise indicated)

| d) | Reserve quantities information

As presented in note 4.1, proven reserves of oil and natural gas are the volumes of oil and natural gas that, through analysis of geoscience and engineering data, can be estimated with reasonable certainty as being, as of a certain date, economically recoverable from known reservoirs and with the economic conditions, operational techniques and existing government standards, until the expiration of the contracts that provide for the right to operate, unless evidence provides reasonable certainty of renewal. The hydrocarbon extraction project must have started or there must be reasonable certainty that the project will start within a reasonable time. These estimates of oil and natural gas reserves require a high level of judgment and complexity, and influence different items in the company's Financial Statements.

The Company’s estimated net proved oil and gas reserves and changes thereto for the years 2024, 2023 and 2022 are presented in the following table. Proved reserves are estimated in accordance with the reserve definitions prescribed by the Securities and Exchange Commission.

Proved developed oil and gas reserves are proved reserves that can be expected to be recovered: (i) through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and (ii) through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is done by means not involving a well.

In some cases, there is a need for substantial new investments in additional wells or equipment to recover these proved reserves, which are called undeveloped proved reserves.

Reserve estimates are subject to variations due to technical reservoir uncertainties and changes in economic scenarios.

A summary of the annual changes in the proved reserves of oil is as follows (in millions of barrels):

In 2023 we standardize the conversion between gas and oil equivalent to 5,614.65 ft3 = 1 boe, equivalent to the conversion used in contracts in Brazil. The quantities from previous years are restated with the new conversion.

The natural gas production presented in these tables is the volume extracted from our proved reserves, including gas consumed in operations and excluding reinjected gas. Our disclosed proved gas reserves include volumes of gas consumed, which represent 36% of our total proved natural gas reserves in 2024.

The tables below summarize information on changes in proven oil and gas reserves, in millions of barrels of oil equivalent, of our consolidated and equity-invested entities for 2024, 2023 and 2022:

In 2023 we standardize the conversion between gas and oil equivalent to 5,614.65 ft3 = 1 boe, equivalent to the conversion used in contracts in Brazil. The quantities from previous years are restated with the new conversion.

In 2024, we incorporated 1,330 million boe of proved reserves by revisions to previous estimates, composed of:

(i) addition of 883 million boe due to new projects, mainly in the Atapu and Sépia fields, and other fields in the Santos, Campos and Solimões Basins;

(ii) addition of 447 million boe resulting from the good performance of assets, mainly in the Búzios, Itapu, Tupi and Sépia fields, in the Santos Basin and other revisions.

We had no relevant changes in reserves related to changes in the price of oil.

The Company's total proved reserve in 2024 resulted in 11,386 million boe, considering the variations described above and discounting the year's production of 865 million boe. This production refers to volumes that were included in our reserves and, therefore, does not consider natural gas liquids, since the reserve is estimated at a reference point prior to gas processing, except in the United States and Argentina. Production also does not consider volumes of injected gas, the production of long-term tests in exploratory blocks and production in Bolivia, since the Bolivian Constitution does not allow the Company to record reserves.

In 2023, we incorporated 1,262 million boe of proved reserves by revising previous estimates, including:

(i) addition of 1,092 million boe arising from the good performance of assets, mainly in Búzios, Tupi and Atapu fields, in the Santos Basin;

(ii) addition of 170 million boe due to new projects and other revisions.

We did not have relevant changes on reserves related to the variation in the oil price.

In addition, we incorporated 237 million boe from discoveries and extensions, mainly due to the declaration of commerciality of Raia Manta and Raia Pintada fields (non-operated), in the Campos Basin.

Moreover, proved reserves were reduced by 155 million boe, resulting from sales.

The Company's total proved reserve resulted in 10,921 million boe in 2023, considering the variations above and the reduction from 2023 production of 894 million boe. Production refers to volumes that were previously included in our reserves and, therefore, does not consider natural gas liquids, since the reserve is estimated at a reference point prior to gas processing, except in the United States of America and Argentina. The production also does not consider volumes of injected gas, the production of Extended Well Tests in exploratory blocks and production in Bolivia, since the Bolivian Constitution does not allow the registration of reserves by the Company.

SUPPLEMENTARY INFORMATION (Unaudited) PETROBRAS (In millions of reais, unless otherwise indicated)

In 2022, we incorporated 1,989 million boe of proved reserves by revising previous estimates, including:

(i) addition of 1,279 million boe due to new projects, mainly in Búzios field and in other fields in the Santos and Campos Basins; and

(ii) addition of 710 million boe arising from other revisions, mainly due to good performance of reservoirs in the pre-salt layer of Santos Basin and to the contract term extension of Rio Urucu and Leste do Urucu fields. We did not have relevant changes related to the variation in the oil price.

The addition in our proved reserves were partially offset by the reduction of 536 million boe, due to the effects of the transfer of interests of 5% of the Surplus Volume of the Transfer of Rights of Búzios field, of the write-offs related to the Co-Participation Agreements of Atapu and Sepia fields and of sales of properties in mature fields.

The Company's total proven reserve in 2022 resulted in 10,473 million boe, considering the incorporations, reviews and assignments of rights described above and discounting the year's production of 860 million boe. This production refers to volumes that were included in our reserves and, therefore, does not consider natural gas liquids, since the reserve is estimated at a reference point prior to gas processing, except in the United States and Argentina. Production also does not consider volumes of injected gas, the production of long-term tests in exploratory blocks and production in Bolivia, since the Bolivian Constitution does not allow the recording of reserves.

e) Standardized measure of discounted future net cash flows relating to proved oil and gas quantities and changes therein

The standardized measure of discounted future net cash flows, related to the above proved oil and gas reserves, is calculated in accordance with the requirements of Codification Topic 932 – Extractive Activities – Oil and Gas.

Estimates of future cash inflows from production are calculated by applying the average price during the 12-month period prior to the closing date, determined as an unweighted arithmetic average of the first price of each month within that period, unless prices are set by contractual agreements, excluding indexes based on future conditions. Variations in future prices are limited to variations foreseen in existing contracts at the end of each year. Future development and production costs correspond to the estimated future expenditures necessary to develop and extract the estimated proven reserves at the end of the year, including abandonment costs, based on cost indications at the end of the year, assuming as a premise the continuity of economic conditions at the end of the year. The estimated future income tax is calculated using the official rates in force at the end of the year. In Brazil, together with income tax, future social contributions are included. The amounts presented as future income tax expenses include permitted deductions, to which official rates apply. Net discounted future cash flows are calculated using discount factors of 10%, applied mid-year. This discounted future cash flow requires estimates of when future expenditures will be incurred and when reserves will be extracted, year by year.

SUPPLEMENTARY INFORMATION (Unaudited) PETROBRAS (In millions of reais, unless otherwise indicated)

The valuation prescribed under Codification Topic 932 – Extractive Activities – Oil and Gas requires assumptions as to the timing and amount of future development and production costs. The calculations are made as of December 31 each year and should not be relied upon as an indication of Petrobras’ future cash flows or the value of its oil and gas reserves.

Information relating to the standardized measurement of discounted future net cash flows is originally presented in US dollars on SEC Form 20-F and was converted into reais for presentation in these financial statements. Therefore, in order to maintain consistency with the criteria used to measure estimates of future cash inflows, as previously described, the exchange rate used for conversion for each period is derived from the average exchange rate of the US dollar during the 12-month period prior to the closing date, determined as an unweighted arithmetic average of the exchange rate on the first day of each month within that period. The exchange rate variations arising from this conversion are shown as accumulated conversion adjustments in the flow movement tables, as follows:

The plants that are part of this Program, as long as they had started in effective commercial operation by December 31, 2004, are entitled to the supply of natural gas by Petrobras for a period of up to 20 years, counted from the beginning of commercial operation, with a price pre-established and readjusted by American inflation.

The supply of gas to the plants under the PPT generated, in 2024, revenues of R$ 850 and costs of R$ 1,092, generating a negative impact on result of R$ 242.

In 2024, the last agreements covered by the Program were executed and finalized.

II– National Program for Rationalization of the Use of Oil and Natural Gas Products (Programa Nacional de Racionalização do Uso dos Derivados do Petróleo e do Gás Natural – CONPET)

The Program, established through the Decree of July 18, 1991, aims to promote the development of an anti-waste culture in the use of non-renewable natural resources. Petrobras also participates in the Brazilian Vehicle Labeling Program (PBEV), in partnership with the National Institute of Metrology, Quality and Technology (INMETRO), which aims to encourage the production and use of gas appliances and more efficient vehicles. In 2024, the costs associated with CONPET, paid for by the company's budget, amounted to approximately R$ 4 thousand.

(A free translation of the original report in Portuguese, as filed with the Brazilian Securities and Exchange Commission (CVM), prepared in accordance with the accounting practices adopted in Brazil and the International Financial Reporting Standards (IFRS) as issued by International Accounting Standards Board (IASB)
To the Board of Directors and Shareholders of Petróleo Brasileiro S.A. - Petrobras Rio de Janeiro – RJ

Key Audit Matters
Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the financial statements of the current period. These matters were addressed in the context of our audit of the individual and consolidated financial statements as a whole, and in forming our opinion on those individual and consolidated financial statements, and, therefore, we do not express a separate opinion on these matters.

1 - Assessment of the measurement of the actuarial obligation of the defined benefit pension and health care plans
According to notes 4.4 and 18.3 of the individual and consolidated financial statements.
Key audit matter | How the matter was addressed in our audit
The Company sponsors defined benefit pension and health care plans that provide supplementary post retirement benefits and medical care to its employees and former employees. The measurement of the actuarial obligation of the pension and health care plans is dependent, in part, of certain actuarial assumptions. These assumptions include the discount rate and projected medical and hospital costs. The Company hires external actuary to assist in the process of assessing the actuarial assumptions and valuing the actuarial obligation under its pension and health care plans. We considered the measurement of the actuarial obligations for the pension and health care plans as a key audit matter due to the level of judgment inherent to the actuarial assumptions determination, as well as for the impact that changes on these assumptions could have on the actuarial obligations of the pension and health care plans. | Our audit procedures included, but were not limited to: - Tests of design and effectiveness of certain internal controls related to the process of measuring the actuarial liability, including controls related to the development, review and approval of the discount rates assumptions and projected medical and hospital costs; - Assessment of the scope, competency, and objectivity of the external actuary hired to assist in the estimate definition of the actuarial obligations for the pension and health care plans, including the nature and scope of the work performed, their professional qualification and experience; and - Assessment, with the support of our actuarial specialists, of the assumptions such as discount rates and projected medical and hospital costs, including comparing them to data obtained from external sources. According to the evidence obtained from performing the procedures described above, we considered that the measurement of the actuarial liability of the defined benefit pension and health care plans is acceptable in the context of the individual and consolidated financial statements taken as a whole, for the year ended December 31, 2024.

2 - Evaluation of the impairment testing of exploration and production cash generating units
According to notes 4.2.1, 4.2.2, 4.2.2(a) and 25 of the individual and consolidated financial statements.
Key audit matter | How the matter was addressed in our audit
The Company identifies its cash generating units (“CGUs”), estimates the recoverable amount of each CGUs based on a projected cash flow for each CGU, and compares to the carrying amount of these CGUs. The cash flow projections used to determine the recoverable amount depend on certain future assumptions such as: Brent oil price, exchange rate (Brazilian Real/US Dollar), capitalizing expenditures (”CAPEX”), operating expenditures (“OPEX”), and volume and timing of recovery of the oil and gas reserves. The recoverable amount is also sensitive to changes in the discount rate used in the cash flow. In addition, the definition of exploration and production segment CGUs considers operational factors that impact the interdependencies between oil and gas assets, and, may result in redefinition through aggregations or segregations of the exploration and production areas into CGUs. We considered the impairment testing of exploration and production cash generating units as a key audit matter due to the level of complexity and subjectivity on the definition of exploration and production´s CGUs, and the impact that changes in future assumptions could have on the estimate of the recoverable amount. | Our audit procedures included, but were not limited to: - Tests of design and effectiveness of certain internal controls related to the process of determining the recoverable amount of exploration and production´s CGU assets, including controls related to the review and approval of the determination of the CGUs, and of the key assumptions used to estimate the recoverable amount; - Assessment of the operational factors considered by the Company for changes in exploration and production CGUs during the year, and compared them to information obtained from internal and external sources; - Assessment of the determination of recovery of oil and gas reserves estimates internally prepared, by comparing it with volumes certified by external reservoirs specialists hired by the Company, and, for a sampling selection of CGUs, with historical data on production; - Assessment of the scope, competency, and objectivity of the Company´s internal engineers responsible for the estimate of the oil and gas reserves, as well as the external reservoir specialists hired by the Company, this included assessing the nature and scope of the work performed, and their professional qualifications and experience; - Assessment, for a sampling selection of CGUs, of the CAPEX and OPEX used on the cash flows projection by comparing to the same business plan approved by the Company, and its long-term budgets; - Assessment of Company’s ability to project cash flows by comparing the estimated cash flows with actual Company´s cash flows for the year ended December 31, 2024 for a selection of CGUs; and - Assessment, with the support of our valuation specialists, of the key assumptions used in the impairment test, such as discount rate, future price of oil and natural gas and exchange rates, comparing them to external market data. During the course of our audit procedures, was identified unrecorded adjustment that affect the measurement and disclosure of the recoverable amount of the CGUs, which was not corrected by management, since it was considered to be immaterial. According to the evidence obtained from performing the procedures described above, we considered that the recoverable amounts for assets of the exploration and production cash generating units are acceptable in the context of the individual and consolidated financial statements taken as a whole, for the year ended December 31, 2024.

131

3 - Evaluation of the estimate of the provision for decommissioning costs
According to notes 4.6 and 20 of the individual and consolidated financial statements.
Key audit matter | How the matter was addressed in our audit
As a part of its operations, the Company incurs on costs related to the obligation to restore and rehabilitate the environment upon the area abandonment. The Company’s estimate of the provision for decommissioning costs includes assumptions in relation to the extent of the obligations assumed for environmental restoration, which includes the decommissioning costs and removal of oil and gas production facilities, as well as the timing estimated of the abandonment. We considered the evaluation of the estimate of the provision for decommissioning costs as a key audit matter due to the level of judgment involved on determining the respective assumptions, especially on the extent of the obligations assumed for the environmental repair, which is the criteria to be met when the removal and restoration actually occurs, the timing and estimated costs of abandonment. | Our audit procedures included, but were not limited to: - Tests of design and effectiveness of certain internal controls related to the process of defining the provision for decommissioning areas estimate, including controls related to the development, review and approval of the key assumptions such as timing of area abandonment and estimated costs of abandonment; - Assessment of the assumptions of abandonment timing used by the Company, by comparing the production curves and useful life of the oil and gas reserves used in the estimate, with oil and gas reserve volumes certified by external reservoirs specialists hired by the Company; - Assessment, with the support of our infrastructure valuation specialists, of the method used to define the extent of decommissioning work in the determination of the estimated costs by comparing the method to applicable regulatory requirements and relevant industry practices, as well as the assessment of the estimated costs of abandonment by comparing certain costs to existing contracts; - Assessment of the scope, competency, and objectivity of the Company´s internal engineers responsible for the production curves and useful life of the oil and gas reserves, as well as the external reservoir specialists hired by the Company, which included assessing the nature and scope of the work performed, and their professional qualifications and experience; and - Assessment of Company’s ability to prepare this estimate by comparing a sampling selection of actual expenditure incurred with the decommissioning of oil and gas production facilities already under abandonment, to the provision for decommissioning previously recognized for such facilities. According to the evidence obtained from performing the procedures described above, we considered that the amount of provision for decommissioning costs is acceptable in the context of the individual and consolidated financial statements taken as a whole, for the year ended December 31, 2024.
Other matters - Statements of value added
The individual and consolidated statements of value added for the year ended December 31, 2024, prepared under the responsibility of the Company's management, and presented as supplementary information for IFRS purposes, were submitted to the same audit procedures followed together with the audit of the Company's financial statements. In order to form our opinion, we evaluated whether these statements are reconciled to the financial statements and to the accounting records, as applicable, and whether their form and content are in accordance with the criteria set on Technical Pronouncement CPC 09 (R1) - Statement of Value Added. In our opinion, these statements of value added have been adequately prepared, in all material respects, according to the criteria set on this Technical Pronouncement and are consistent with the individual and consolidated financial statements taken as a whole.

132

Other information accompanying the individual and consolidated financial statements and the auditor's report
Management is responsible for the other information. The other information comprises the Management’s Report and the Financial Performance Report. Our opinion on the individual and consolidated financial statements does not cover the Management’s Report and the Financial Performance Report and we do not express any form of assurance conclusion thereon. In connection with our audit of the individual and consolidated financial statements, our responsibility is to read the Management’s Report and the Financial Performance Report and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit, or otherwise appears to be materially misstated. If, based on the work performed, we conclude that there is material misstatement in the Management’s Report and the Financial Performance Report, we are required to report on that fact. We have nothing to report in this regard.
Responsibilities of Management and Those Charged with Governance for the Individual and Consolidated Financial Statements
Management is responsible for the preparation and fair presentation of the individual and consolidated financial statements in accordance with the accounting practices adopted in Brazil and the International Financial Reporting Standards as issued by the International Accounting Standards Board (IASB), and for such internal control as management determines is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error. In preparing the individual and consolidated financial statements, management is responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Company and its subsidiaries, or to cease operations, or has no realistic alternative but to do so. Those charged with governance are responsible for overseeing the Company and its subsidiaries’ financial reporting process.
Auditors’ Responsibilities for the Audit of the Individual and Consolidated Financial Statements

Our objectives are to obtain reasonable assurance about whether the individual and consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors’ report that includes our opinion. Reasonable assurance is a high level of assurance, but it is not a guarantee that an audit conducted in accordance with Brazilian and International Standards on Auditing will always detect possible existing material misstatements. Misstatements can arise from fraud or error and are considered material if, individually or in aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements. As part of our audit in accordance with Brazilian and International Standards on Auditing, we exercise professional judgment and maintain professional skepticism throughout the audit. We also: - Identify and assess the risks of material misstatement of the individual and consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve the act of collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. - Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control.

133

- Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management. - Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s and its subsidiaries' ability to continue as a going concern. If we conclude that a material uncertainty exists, then we are required to draw attention in our auditors’ report to the related disclosures in the individual and consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor´s report. However, future events or conditions may cause the Company and its subsidiaries to cease to continue as a going concern. - Evaluate the overall presentation, structure and content of the financial statements, including the disclosures, and whether the individual and consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation. - Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on the individual and consolidated financial statements. We are responsible for the direction, supervision and performance of the group audit. We remain solely responsible for our audit opinion. We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit. We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and communicate with them all relationships and other matters that may reasonably be thought to bear on our independence and where applicable, actions taken to eliminate threats or safeguards applied. From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the financial statements of the current year and are therefore the key audit matters. We describe these matters in our auditors’ report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

The members of the Statutory Audit Committee declare that they are not aware of any situation of significant divergence between the Management, the Independent Auditors of KPMG, and with the committee itself, in relation to the financial statements for the fiscal year ended December 31, 2024 and taking into account the attributions and limitations inherent to the scope of their activities, considering all the analyses, studies and debates carried out during the meetings and the monitoring and supervision work carried out, with emphasis on the activities of monitoring the quality of the financial statements, internal controls, compliance and risk management, in order to ensure the balance, transparency and integrity of the financial information published for investors, previously described herein in a summarized manner, concluded that:

(i) the internal control processes for the production of financial reports were effective and the actions to prevent and combat fraud and corruption were adequate;

(ii) the Internal Audit has a financial budget compatible with its organizational structure, allowing it to satisfactorily perform its functions, with independent action;

(iii) the Independent Audit was effective and no occurrences that could compromise its independence were reported;

(iv) the management and monitoring of the main risk factors were managed by Management;

(v) ​​the transactions with related parties assessed and monitored in the period complied with Petrobras' Related Party Transactions Policy and provided evidence of the existence of strictly commutative conditions, transparency, equity, the Company's interest and adequate and timely disclosure; and

(vi) the parameters on which the actuarial calculations were based, as well as the results of the benefit plans maintained by the Petrobras Social Security Foundation, are reasonable and in line with best market practices.

As a result of the assessments based on the information received from Petrobras' Management, the work of the Internal Audit and the examinations of the financial statements by the independent auditors, who issued a report with an unqualified opinion, the Statutory Audit Committee recommends the approval, by the Board of Directors, of the financial statements for the fiscal year ended December 31, 2024 for subsequent submission to the General Shareholders' Meeting.
