Trade and other receivables are generally classified as measured at amortized cost, except for receivables with final price linked to changes in commodity price after their transfer of control, which are classified as measured at fair value through profit or loss, amounting to R$ 4,746 as of March 31, 2026 (R$ 2,213 as of December 31, 2025).

The balance of receivables from divestment and Transfer of Rights Agreement is mainly related to the earnout of the Atapu and Sépia fields, totaling R$ 1,104 (R$ 2,191 as of December 31, 2025), from the sale of the Roncador field for R$ 1,133 (R$ 1,464 as of December 31, 2025) and the Potiguar cluster for R$ 416 (R$ 862 as of December 31, 2025).

The reduction in the "Other receivables" balance is mainly related to receipts concerning the Tupi shared reservoir, according to note18.4.

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 March 31, 2026, the balance advanced by suppliers, within the scope of the program, is R$ 905 (R$ 733 as of December 31, 2025) and has a payment term from 6 to 92 days and a weighted average term of 43 days (payment term from 7 to 93 days and a weighted average term of 55 days in 2025), after the contracted commercial conditions have been met.

13.1.3.Uncertain tax treatments on income taxes

As of March 31, 2026, the Company has R$ 3,294 (R$ 3,379 as of December 31, 2025) of uncertain tax treatments, provisioned in the statement of financial position, mainly related to the deduction of amounts paid in the basis of calculation of income taxes in Brazil, as well as to the incidence of Corporate Income Tax (CIT) on transactions abroad, related to judicial and administrative proceedings.

In addition, the Company has R$ 28,597 of uncertain tax treatments (R$ 25,151 as of December 31, 2025), not provisioned, in Brazil and abroad, related to judicial and administrative proceedings, mainly relating to income of subsidiaries abroad.

As of March 31, 2026, the Company has other positions that can be considered as uncertain tax treatments on income taxes amounting to R$ 27,813 (R$ 27,026 as of December 31, 2025), given the possibility of different interpretation by the tax authority. These uncertain tax treatments are supported by technical assessments and tax risk assessment methodology. Therefore, Petrobras believes that such positions are likely to be accepted by the tax authorities (including judicial courts).

Thus, as of March 31, 2026, the total amount of uncertain tax treatments, in Brazil and abroad, amounts to R$ 59,704 (R$ 55,556 as of December 31, 2025), for which Petrobras will continue to defend its position.

**13.4.**Export tax on crude oil and diesel

On March 12, 2026, Provisional Measure No. 1,340 was published, establishing the levy of Export Tax (IE) over crude oil, bituminous minerals and road-use diesel.

The tax is non-recoverable but deductible on the tax base of Corporate Income Tax (IRPJ) and Social Contribution on Net Income (CSLL). The tax is levied on crude oil exports at a 12% rate and on diesel oil exports at a 50% rate.

The Ministry of Finance Ordinance No. 674/1994, which provides for the payment of Export Tax, establishes that the deadline for payment of the tax will be up to 15 (fifteen) days for diesel and 60 (sixty) days for crude oil, counted from the date of registration of the declaration for customs clearance.

Health Care Plan

The health care plan Saúde Petrobras – AMS is managed and run by Petrobras Health Association (Associação Petrobras de Saúde – APS), a nonprofit civil association, and includes prevention and health care programs. The plan offers assistance to all employees, retirees, pensioners and eligible family members, according to the rules of the plan, and is open to new employees.

Benefits are paid by the Company based on the costs incurred by the beneficiaries. The financial participation of the Company and the beneficiaries on the expenses are provided for in the plan rules and in the ACT, currently at 70% by the Company and 30% by the participants.

Pension plans

The Company’s post-retirement plans are managed by Petros Foundation, a nonprofit legal entity governed by private law with administrative and financial autonomy.

Pension plans in Brazil are regulated by the National Council for Supplementary Pension (Conselho Nacional de Previdência Complementar – CNPC), which establishes all guidelines and procedures to be adopted by the plans for their management and relationship with stakeholders.

Petros Foundation periodically carries out revisions of the plans and, when applicable, establishes measures aimed at maintaining the financial sustainability of the plans.

On March 24, 2026, the Deliberative Council of Petros Foundation approved the financial statements of the pension plans sponsored by the Company for the year ended December 31, 2025.

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

The following table presents the reconciliation of the deficit of Petros Plan registered by Petros Foundation as of December 31, 2025, with the net actuarial liability registered by the Company on the same date:

	PPSP-R ^(1)^	PPSP-NR ^(1)^
Accumulated deficit according to CNPC – Petros Foundation	1,299	649
Ordinary and extraordinary future contributions - sponsor	23,514	6,926
Contributions related to the TFC - sponsor	4,323	3,121
Financial assumptions (interest rate and inflation), changes in fair value of plan assets and actuarial valuation method	(11,272)	(2,730)
*Net actuarial liability according to CVM* – Sponsor Company**	17,864	7,966
(1) It includes the balance of PPSP-R pre-70 and PPSP-NR pre-70.

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 the Superintendência Nacional de PrevidênciaComplementar - PREVIC (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 at market value or on the curve, while the Company marks all of them at market value.

14.2.1 Amounts in the financial statements related to defined benefit plans

Net actuarial liabilities represent the obligations of the Company, net of the fair value of plan assets (when applicable), at present value.

Additionally, it contributed R$ 396 (R$ 336 for the period from January to March 2025) to the defined contribution portion of plan PP2 and R$ 3 to plan PP3 (R$ 3 for the period from January to March 2025), which were recognized as operating expenses for the period.

15.	Provisions for legal proceedings, judicial deposits and contingent liabilities

15.1 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:

·	Tax claims including: (i) VAT tax collection - bunker<br>oil involving several states; (ii) social security contributions - claims for alleged non-payment on allowances and bonuses; and (iii)<br>claims relating to benefits previously taken for Brazilian federal tax credits applied that were subsequently alleged to be disallowable,<br>including disallowance of PIS and COFINS tax credits.
·	Labor claims, in particular: (i) several individual<br>and collective labor claims; and (ii) legal actions from outsourced employees.
---	---
·	Civil claims, in particular: (i) lawsuits related<br>to contracts; (ii) legal and administrative proceedings involving fines applied by the ANP - Brazilian Agency of Petroleum, Natural Gas<br>and Biofuels (Agência Nacional de Petróleo, Gás Natural e Biocombustíveis), mainly relating to production<br>measurement systems, as well as administrative and judicial proceedings that discuss the difference between special participation and<br>royalties in several oil fields; (iii) lawsuits that discuss matters related to pension plans managed by Petros; (iv) civil claims involving<br>disposal of assets; and (v) lawsuits that discuss compensation related to expropriation and right-of-way easements.
---	---
·	Environmental claims, specially: (i) fines relating<br>to an environmental accident in the State of Paraná in 2000; (ii) fines relating to the Company’s offshore operation;<br>and (iii) public civil action for oil spill in 2004 in Serra do Mar State Park.
---	---

Provisions for legal proceedings are set out as follows:

| **NOTES TO THE FINANCIAL STATEMENTS**<br><br>PETROBRAS<br><br>(Expressed in millions of reais, unless otherwise indicated) |

| --- | | | Consolidated | | | --- | --- | --- | | Non-current liabilities | 03.31.2026 | 12.31.2025 | | Labor claims | 4,387 | 3,803 | | Tax claims | 3,173 | 4,057 | | Civil claims | 8,835 | 8,808 | | Environmental claims | 1,191 | 1,213 | | Total | 17,586 | 17,881 | | | Consolidated | | | | 2026 Jan-Mar | 2025 Jan-Mar | | Opening Balance | 17,881 | 17,543 | | Additions, net of reversals | (50) | 494 | | Use of provision | (995) | (2,409) | | Accruals and charges | 754 | 672 | | Others | (4) | (30) | | Closing balance | 17,586 | 16,270 |

In preparing its unaudited condensed consolidated interim financial statements for the three-month period ended March 31, 2026, the Company considered all available information concerning legal proceedings in which the Company is a defendant, in order to estimate the amounts of obligations and probability that outflows of resources will be required.

In the period from January to March 2026, the decrease of R$ 295 in the provisioned liability is mainly due to reductions related to the incidence of ICMS (Value Added Tax) on the tax amnesty program, according to note 13.3, mainly offset by provisions related to labor claims.

15.2 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
Non-current assets	03.31.2026	12.31.2025
Tax	57,368	55,972
Labor	4,583	4,617
Civil	20,840	20,370
Environmental and others	545	551
Total	83,336	81,510
	Consolidated

Use	(153)	(194)
Accruals and charges	1,857	1,467
Others	(1)	(1)
Closing balance	83,336	75,078

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 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 March 31, 2026, the balance of production capacity held in guarantee in the NJP is R$ 8.583 (R$ 7.795 as of December 31, 2025).

15.3 Contingent liabilities

The estimates of contingent liabilities are indexed to inflation and updated by applicable interest rates. As of March 31, 2026 estimated contingent liabilities for which the possibility of loss is classified as possible are set out in the following table:

	Consolidated
Nature	03.31.2026	12.31.2025
Tax	153,807	136,375
Labor	10,173	10,244
Civil	70,488	70,276
Environmental and others	8,254	7,673
Total	242,722	224,568

The main contingent liabilities are:

·	Tax matters comprising: (i) disapproval of PIS and<br>COFINS tax compensation due to credit disallowance; (ii) income from foreign subsidiaries and associates not included in the computation<br>of taxable income (IRPJ and CSLL); (iii) collection of ICMS involving several states; (iv) incidence of social security contributions<br>on the payment of bonuses; (v) collection of PIS and COFINS, resulting from the payment of taxes negotiated with the Brazilian Federal<br>Government, excluding the payment of fines; and (vi) withholding income tax (IRRF) on remittances for payments of vessel charters.
·	Labor matters, comprising several labors claims;
---	---
·	Civil matters comprising mainly: (i) administrative<br>and legal proceedings challenging an ANP order requiring Petrobras to pay additional special participation fees and royalties (production<br>taxes) with respect to several oil fields, including unitization of deposits and reservoirs; (ii) lawsuits<br>related to contracts; (iii) claims that discuss topics related to pension plans managed by<br>Petros; (iv) fines from regulatory agencies, mainly ANP; and (v) judicial and arbitration proceedings that discuss disposal of assets<br>carried out by Petrobras; and
---	---
·	Environmental matters comprised mainly: (i) fines<br>related to the Company operations; (ii) fishermen's indemnities; and (iii) indemnities for environmental damage.
---	---

From January to March 2026, the increase in contingent liabilities was a result mainly from the following changes:

·	R$ 11,266 relating to the reversal of ICMS (VAT Tax)<br>credits arising from the entry of goods in transactions prior to the fuel sales;
·	R$ 3,263 related to proceedings concerning adjustments<br>to the income tax and social contribution tax base arising from ancillary obligations and contributions to the Petros Plan;
---	---
·	R$ 1,568 related to ICMS VAT tax credits on the acquisition<br>of goods that, according to the tax authorities, do not constitute fixed assets;
---	---
·	R$ 1,208 related to administrative and judicial proceedings<br>discussing differences in special participation and royalties in various oil fields, including the unification of deposits and reservoirs;
---	---
·	R$ 659 related to civil litigation involving contractual<br>issues; and

| --- | | · | R$ 521 related to the disallowance of credits and deduction from the PIS and COFINS tax base. | | --- | --- |

These effects were mainly offset by civil litigation involving the sale of assets totaling R$ 1,885.

15.4 Collective action and related proceedings

15.4.1 Collective 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 October 30, 2024, after the parties' comments on the technical evidence, the District Court of Rotterdam 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 District Court of Rotterdam 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 District Court of Rotterdam 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 from July 2005 to February 2015; and (ii) prescription of requests formulated in accordance with Spanish legislation.

Petrobras, the Foundation and PGF have appealed against the ruling and previous interim decisions, and their appeals are pending of judgment.

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 and PGF 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 damage 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 court, 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 Hague Court of Appeal 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.

| 38 |

| **NOTES TO THE FINANCIAL STATEMENTS**<br><br>PETROBRAS<br><br>(Expressed in millions of reais, unless otherwise indicated) |

| --- |

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 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 Supreme Federal Court.

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

15.4.2 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, on September 3, 2025, the lower court recognized the statute of limitations on the criminal action and ordered its dismissal. The judgment dismissing the criminal action followed the Court of Appeals' decision on April 3, 2025, which overturned the previous decision to prosecute Petrobras and the previously ordered injunction. On March 2, 2026, the second instance of the Argentine Court rejected the Association's appeal against the dismissal of the criminal case and, on April 23, 2026, ruled that the appeal for cassation filed by the Association was inadmissible. This decision is subject to appeal.

15.4.3 Arbitrations proposed bynon-controlling Shareholders in Brazil

There were no relevant changes in the three-month period ended March 31, 2026.

For more information, see note 20.5 to the financial statements for the year ended December 31, 2025.

(4) In the case of land and assets under construction, it refers only to impairment losses.
(5) It mainly includes transfers between classes of assets and transfers from advances to suppliers.

Additions in assets under construction, from January to March 2026, are mainly due to investments in the development of production in the Búzios field and other fields in the Santos basin, Espírito Santo basin and Campos basin. As for additions to right-of-use assets, primarily relate to the rigs for E&P operations, with the corresponding record on leasing liability (note 25).

Petrobras has AIPs signed in Brazil with partner companies in E&P consortia which provides for the equalization of expenses and production volumes, mainly related to the following fields: Agulhinha, Berbigão, Budião Noroeste, Budião Sudeste, the pre-salt layer of Jubarte, and Sururu.

The table below presents changes in the estimate of amounts relating to the execution of the AIPs submitted to the approval of the ANP:

	Jan-Mar/2026	Jan-Mar/2025
Opening balance, net	2,248	3,575
Additions (write-offs) of assets	(185)	(221)
Other (income) and expenses	36	23
Indexation charges	(140)	−
Payments made	(849)	−
Cash inflow	3,102	−
Closing balance, net	4,212	3,377

These changes reflect the best available estimate of the assumptions used in the calculation base and the sharing of assets in areas to be equalized.

Sapinhoá Shared Reservoir

On March 12, 2026, Petrobras paid R$ 219 to the Brazilian Federal Government, represented by PPSA, regarding the signing of the Amendment to the AIP of the Sapinhoá Shared Reservoir, approved by ANP in the third quarter of 2025.

Tupi Shared Reservoir

On March 31, 2026, Petrobras received R$ 3,102 from partner companies and paid R$ 624 to the Brazilian Federal Government represented by Pré-Sal Petróleo (PPSA), in relation to the equalization process of the Tupi Shared Reservoir.

18.5 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 three-month period ended March 31, 2026, the capitalization rate was 7.25% p.a. (7.05% p.a. for the three-month period ended March 31, 2025).

26.4 Distributions to shareholders

Dividends and interest in capitalrelating to 2025

On April 16, 2026, the Annual General Shareholders Meeting approved dividends and interest on capital relating to 2025, amounting to R$ 41,236 (R$ 3.19936420 per outstanding share). This amount includes R$ 33,164 anticipated during 2025 (updated by Selic interest rate from the date of each payment to December 31, 2025) and R$ 8,072 of complementary dividends which is accounted for as additional dividends and interest on capital proposed.

The complementary dividends of R$ 8,072, equivalent to R$ 0.62622908 per preferred and common share in circulation, was reclassified from shareholders’ equity to liabilities on the date of approval of the Annual General Meeting and will be paid in two equal installments on May 20 and June 22, 2026, in the form of interest on capital, updated by the Selic rate from December 31, 2025, until the date of each payment.

The interest on capital from the supplementary remuneration for the 2025 fiscal year resulted in a tax credit for income tax and social contribution of R$ 2,744. Withholding income tax was applied to the interest, except for immune and exempt shareholders, as established in current legislation. The tax benefit related to the supplementary interest on capital will be recognized in the second quarter of 2026.

On November 27, 2025, law No. 15,270/2025 was published, establishing the withholding income tax at a 10% rate on dividends distributed to individuals domiciled in Brazil, when such dividends exceed R$ 50 thousand per month. The 10% rate also applies to dividends distributed abroad to individuals or legal entities, regardless of the amount, except in specific situations provided for by law. In addition, supplementary law No. 224/2025 increased the withholding income tax rate applicable to interest on capital from 15% to 17.5%. Both laws came into effect on January 1, 2026.

Dividends and interest in capitalpayable

As of March 31, 2026, there is no outstanding balance of dividends and interest on capital payable to Petrobras shareholders (R$ 11,415 as of December 31, 2025), as shown in the transaction below.

Unclaimed dividends and interestin capital

As of March 31, 2026, the balance of dividends and interest on capital not claimed by shareholders of Petrobras is R$ 982 (R$ 1,029 on December 31, 2025) recorded as other current liabilities, as described in note 17. The payment of these dividends and interest on capital 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.

Basic earnings per share are calculated by dividing the net income attributable to shareholders of Petrobras by the weighted average number of outstanding shares during the period.

Diluted earnings per share are calculated by adjusting the net income 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.

27.3 Market risks

27.3.1 Foreign exchange risk management

a)	Cash flow hedge involving the Company’sfuture exports

The Company uses hedge accounting for the risk arising from foreign 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 March 31, 2026, 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$ 5.2194 exchange rate are set out below:

| 55 |

In the three-month period ended March 31, 2026, the Company recognized a R$ 204 gain, within foreign exchange rate gains (losses), due to ineffectiveness (a R$ 479 gain in the same period of 2025).

The average ratio of future exports for which cash flow hedge accounting was designated to highly probable future exports is 71.2%.

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

	Jan-Mar/2026	Jan-Mar/2025
Opening balance	(41,222)	(98,094)
Recognized in equity	19,734	28,940
Reclassified to the statement of income	2,665	4,228
Other comprehensive income (loss)	22,399	33,168
Closing balance	(18,823)	(64,926)

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 future revisions of the Company’s business plans. 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 2026-2030, would not indicate a reclassification from equity to the statement of income.

A schedule of expected reclassification of cumulative foreign exchange rate losses recognized in other comprehensive income to the statement of income as of March 31, 2026, is set out below:

	Consolidated
		2026	2027	2028	2029	2030	2031<br><br> <br>onwards	Total

b)	Derivative financial instruments not designated for hedge accounting
---	---

In 2019, Petrobras contracted a cross-currency swap aiming to protect against exposure arising from the 7^th^ issuance of debentures, for IPCA x CDI operations, maturing in September 2029 and September 2034, and for CDI x U.S. Dollar operations, maturing in September 2029.

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 554-basis point effect on the estimated interest rate. The effect of this sensitivity analysis, keeping all other variables constant, is shown in the following table:

| 56 |

| --- | | | Consolidated | | --- | --- | | Financial Instruments | Reasonably possible scenario | | Swap CDI x USD | (74) |

c)	Sensitivity analysis for foreign exchange raterisk 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 3.46% depreciation of the<br>real;
·	euro x U.S. dollar - a 4.19% appreciation of the<br>euro;
---	---
·	pound sterling x U.S. dollar - a 3.15% appreciation<br>of the pound sterling;
---	---
·	renminbi x U.S. dollar – a 1.62% appreciation<br>of the renminbi.
---	---

The reasonably possible scenario has the same references and considers the risk of a 20% depreciation of the closing exchange rate of the quarter against the reference currency, except for assets and liabilities of foreign subsidiaries, when transacted in a currency equivalent to their respective functional currencies.

27.3.2Risk 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 March 31, 2026. 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.

Risk	Operations	Probable scenario	Reasonably possible scenario
Derivatives not designated for hedge accounting
Crude oil and oil products - price changes	Future and forward contracts (Swap)	−	(204)
Soybean oil - price changes	Future and forward contracts (Swap)	−	(7)
Soybean oil - price changes	Options	−	(3)
Foreign currency - depreciation BRL x USD	Forward contracts	−	(13)
Total		−	(227)

The positions with commodity derivatives are presented in note 27.2.

27.3.3Interest rate risk management

The Company prefers not to use derivative financial instruments to manage the risk of interest rate fluctuations, adopting structural actions that take into account the effects on integrated risk exposure.

In this sensitivity analysis, probable scenario represents the amounts to be disbursed by Petrobras relating to the payment of interest on debts linked to floating rates as of March 31, 2026. The reasonably possible scenario represents the disbursement if there is a 40% change on these rates, keeping all other variables constant.

(1) Secured Overnight Financing Rate.
(2) Loan Prime Rate.

27.4Liquidity 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 with 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 business plan.

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

In addition, the company maintains committed credit lines (revolving credit facilities) contracted as a liquidity reserve in adverse situations, as per explanatory note 24.5, and regularly assesses market conditions and may carry out repurchase transactions of its securities or those of its subsidiaries in the international capital market, through various means, including repurchase offers, redemptions of securities and/or open market operations, provided that they are in line with the company's liability management strategy, which aims to improve the amortization profile and the cost of debt.

The expected cash flows related to indebtedness are presented in notes 24.4 and 25, financing and lease liabilities, respectively.

27.5Credit risk

Credit risk management in Petrobras aims to mitigate risk of not collecting receivables, financial deposits or collateral from third parties or financial institutions through the analysis, granting and management of credit, based on quantitative and qualitative parameters that are appropriate for each market segment in which the Company operates.

As of March 31, 2026, the financial assets of cash and cash equivalents and of financial investments are not past due nor considered to be credit impaired, presenting fair values that are equivalent to or do not differ significantly from their carrying amounts.

The effect of credit risk assessments on trade receivables is available in notes 9.2 and 9.3, which present expected credit losses.

28.	Related party transactions

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

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

28.5.1 Road-use diesel subsidyprogram

In March 2026, the Company adhered to the economic subsidy program for the commercialization of road-use diesel in Brazil, established by Provisional Measure (MP) No. 1,340, of March 12, 2026, of the Federal Government. This program enables the equalization of part of the costs to road-use diesel producers and importers who proves selling prices charged to distributors equal to or lower than the price determined by the Brazilian Federal Government, according to the methodology defined by ANP.

The first subsidy calculation period occurred from March 12 to March 31, 2026, with receipt to be made by the last business day of the month following the respective calculation period, provided that documentation is made available to ANP within the prescribed timeframe and no amendments are required. This documentation is intended to evidence tax compliance and the application of commercialized prices in accordance with applicable legislation.

The subsidy corresponds to R$ 0.32 per liter of commercialized road-use diesel. This program is effective from March 12 to December 31, 2026, and may have earlier termination if the budget limit set by the Brazilian Federal Government is reached.

Revenue recognition in the company's financial statements occurs as road-use diesel fuel is sold and delivered to distributors. This right is recognized in accounts receivable.

As of March 31, 2026, the company has recorded accounts receivable in the amount of R$ 741 relating to the first reporting period foreseen in the program. This amount has an effect on the result of R$ 672, net of PIS and COFINS taxation, according to Note 4.

(A free translation of the original report in Portuguese, as filed with theBrazilian Securities Commission - CVM, prepared in accordance with the Technical Pronouncement CPC 21 (R1) - Interim Financial Reportingand the international accounting standard IAS 34 - Interim Financial Reporting, as issued by the International Accounting Standards Board- IASB)

To the Board of Directors and Shareholders of

Petróleo Brasileiro S.A. - Petrobras

Rio de Janeiro - RJ

Introduction

We have reviewed the individual and consolidated interim financial information of Petróleo Brasileiro S.A. - Petrobras (“the Company”), included in the quarterly information form - ITR for the quarter ended March 31, 2026, which comprises the statement of financial position as of March 31, 2026 and the respective statements of income, comprehensive income, changes in shareholders' equity and of cash flows for the three-months period then ended, including the explanatory notes.

Management is responsible for the preparation of the individual and consolidated interim financial information in accordance with the CPC 21 (R1) – Interim Financial Reporting and the international standard IAS 34 - Interim Financial Reporting, issued by the International Accounting Standards Board - IASB, such as for the presentation of these information in accordance with the standards issued by the Brazilian Securities Commission - CVM, applicable to the preparation of quarterly information - ITR. Our responsibility is to express our conclusion on this interim financial information based on our review.

Scope of the review

We conducted our review in accordance with Brazilian and international standards on reviews of interim financial information (NBC TR 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity and ISRE 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity, respectively). A review of interim financial information consists of making inquiries primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with the auditing standards and, consequently, does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion on the individual and consolidated interim financial information

Based on our review, nothing has come to our attention that causes us to believe that the accompanying individual and consolidated interim financial information included in the quarterly information referred to above has not been prepared, in all material respects, in accordance with CPC 21 (R1) and IAS 34, applicable to the preparation of quarterly information

ITR, and presented in accordance with the standards issued by the Brazilian Securities Commission.

Other matters - Statements of added value

The quarterly information referred to above includes the individual and consolidated statements of added value (DVA) for the three-month period ended at March 31, 2026, prepared under responsibility of Company’s management, and presented as supplementary information for IAS 34 purposes. These statements were submitted to review procedures carried out together with the review of the Company’s interim financial information to conclude that they are reconciled with interim financial information and accounting records, as applicable, and its form and content are in accordance with the criteria defined in CPC 09 (R1) - Statement of Added Value. Based on our review, nothing has come to our attention that causes us to believe that those statements were not prepared, in all material respects, in accordance with the criteria set forth in this Standard with respect to the individual and consolidated interim financial information taken as a whole.
