[6-K] PETROBRAS - PETROLEO BRASILEIRO SA Current Report (Foreign Issuer)

Rhea-AI Filing Summary

Petrobras (PBR) reported stronger year-to-date results. For the nine months ended September 30, 2025, sales revenues were $65.6 billion versus $70.6 billion a year ago, while net income rose to $16.8 billion from $10.4 billion. In Q3 2025, revenue was $23.5 billion (slightly above Q3 2024) and net income reached $6.1 billion. The earnings improvement was supported by lower finance expenses and significant foreign exchange gains, which turned net finance from a loss last year to income this year.

Cash and cash equivalents increased to $9.0 billion from $3.3 billion at year-end 2024. Operating cash flow was $25.9 billion, funding $12.9 billion of capital additions and $6.6 billion in dividends. Total finance debt rose compared to year-end, and lease liabilities increased as new production assets came online. Equity climbed to $79.9 billion, helped by profits and hedge-related other comprehensive income. Decommissioning obligations increased to $30.4 billion. Petrobras settled the EIG dispute for $283 million, ending that litigation, and received favorable developments in certain legal matters abroad.

Insights

Energy & IFRS analyst

Earnings up on FX gains; cash generation remains strong.

Petrobras delivered higher profitability despite lower revenue. Year-to-date net income rose to $16.8B as foreign exchange gains flipped net finance results to income of $3.0B. Q3 net income was $6.1B with stable quarterly revenue versus last year.

Operating cash flow of $25.9B supported $12.9B of capex and $6.6B in dividends. Cash rose to $9.0B while finance debt and lease liabilities increased alongside deployment of FPSOs and other assets. Decommissioning provisions increased to $30.4B, reflecting discounting and portfolio dynamics.

Litigation exposure evolved: the $283M agreement with EIG ended that case, and certain court decisions abroad favored the company in parts. Actual impact depends on future proceedings and appeals disclosed.

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 September 30, 2025, the balance advanced by suppliers, within the scope of the program, is US$ 140 (US$ 134 as of December 31, 2024) and has a payment term from 4 to 93 days and a weighted average term of 54 days (payment term from 7 to 92 days and a weighted average term of 58 days in 2024), after the contracted commercial conditions have been met.

12.1.1. Uncertain tax treatments on income taxes

As of September 30, 2025, the Company has US$ 620 (US$ 767 as of December 31, 2024) 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 US$ 4,581 of uncertain tax treatments (US$ 5,229 as of December 31, 2024), unprovisioned, in Brazil and abroad, on income taxes related to judicial and administrative proceedings, mainly relating to income of subsidiaries abroad and to income taxes over transfer pricing.

As of September 30, 2025, the Company has other positions that can be considered as uncertain tax treatments on income taxes amounting to US$ 5,900 (US$ 4,274 as of December 31, 2024), 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 September 30, 2025, the total amount of uncertain tax treatments amounts to US$ 11,101 (US$ 10,270 as of December 31, 2024), for which Petrobras will continue to defend its position.

12.3. Enrollment in the tax settlement program

In June 2024, Petrobras enrolled in a tax settlement program proposed by the Brazilian National Treasury by means of the Transaction Notice PGFN-RFB 6/2024, closing relevant litigation related to the taxation of remittances abroad, arising from contracts relating to the chartering of vessels and rendering of services, settling debts under dispute (contingent liabilities) relating to the taxation of CIDE, PIS and

COFINS, from 2008 to 2013. This program brought economic benefits, avoiding costs with judicial guarantees, and included a 65% discount on the debt under dispute in Brazilian reais. The payment of the tax settlement was completed in the second half of 2024, as disclosed in the consolidated financial statements as of December 31, 2024, note 17.3.

The effects of enrollment in this program resulted in a US$ 1,929 expense, net of reimbursements to Petrobras made by partners in E&P consortia of the amounts corresponding to their respective interests, whose enrollments in this program were approved in the nine-month period ended September 30, 2024.

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.

In June 2024, the Company and the unions entered into an agreement to resume the cost-sharing arrangement previously practiced, with 70% covered by Petrobras and 30% by the beneficiaries, effective since April 2024 (until March 2024, it was 60% covered by Petrobras and 40% by the beneficiaries).

Due to this agreement, the Company carried out an intermediate remeasurement of the actuarial liabilities of this plan, which resulted in a US$ 23 increase in actuarial liabilities, as follows: (i) a US$ 1,291 expense within other income and expenses, due to the change in the benefit costing; (ii) a US$ 1,265 gain within other comprehensive income due to the revision of actuarial assumptions, mainly the discount rate applied to actuarial liabilities.

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 aiming at maintaining the financial sustainability of the plans.

On March 25, 2025, the Deliberative Council of Petros Foundation approved the financial statements of the pension plans for the year ended December 31, 2024, sponsored by the Company.

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 below presents the reconciliation of the deficit of Petros Plan registered by Petros Foundation as of December 31, 2024 with the net actuarial liability registered by the Company at the same date:

	PPSP-R (1)	PPSP-NR (1)
Deficit registered by Petros	259	93
Ordinary and extraordinary future contributions - sponsor	3,744	1,097
Contributions related to the TFC - sponsor	658	442
Financial assumptions (interest rate and inflation), changes in fair value of plan assets and actuarial valuation method	(1,976)	(474)
Net actuarial liability recorded by the Company	2,684	1,158
(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 Previdência Complementar - 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.

13.2.1. Actuarial liabilities recognized in the statement of financial position, 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.

Changes in the actuarial liabilities related to pension and health care plans with defined benefit characteristics is presented as follows:

13.2.2. Contributions

In the nine-month period ended September 30, 2025, the Company contributed with US$ 780 (US$ 758 in the same period of 2024), to the defined benefit plans (reducing the balance of obligations of these plans, as presented in note 13.2.2), and with US$ 172 and US$ 1, respectively, to the defined contribution portions of PP-2 and PP-3 plans
(US$ 169 for PP-2 and US$ 1 for PP-3 in the same period of 2024), which were recognized in the statement of income.

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

14.1. 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) tax notices for alleged non-compliance with ancillary obligations; (ii) claims relating to benefits previously taken for Brazilian federal tax credits applied that were subsequently alleged to be disallowable, including disallowance of PIS and COFINS tax credits; and (iii) claims for alleged non-payment of social security contributions on allowances and bonuses.

· Labor claims, in particular: (i) several individual and collective labor claims; (ii) actions of outsourced employees; and (iii) 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.

· Civil claims, in particular: (i) lawsuits related to contracts; (ii) lawsuits that discuss matters related to pension plans managed by Petros; (iii) legal and administrative proceedings involving fines applied by the ANP - Brazilian Agency of Petroleum, Natural Gas and Biofuels (Agência Nacional de Petróleo, Gás Natural e Biocombustíveis), mainly relating to production measurement systems; and (iv) administrative and judicial proceedings that discuss the difference between special participation and royalties in several oil fields.

· Environmental claims, specially: (i) fines relating to an environmental accident in the State of Paraná in 2000; (ii) fines relating to the Company’s offshore operation; and (iii) public civil action for oil spill in 2004 in Serra do Mar-São Paulo State Park.

Provisions for legal proceedings are set out as follows:

In preparing its unaudited condensed consolidated interim financial statements for the nine-month period ended September 30, 2025, 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.

14.2. 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:

Non-current assets	09.30.2025	12.31.2024

(1) In the nine-month period ended September 30, 2024, the Company used credits arising from the enrollment to the tax settlement program proposed in the Transaction Notice PGFN-RFB 6/2024 (see note 12.3), which ended legal disputes over relevant litigation related to the incidence of taxes on remittances abroad related to platform chartering.

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 US$ 38 (R$ 200 million), 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 September 30, 2025, the balance of production capacity held in guarantee in the NJP is US$ 2,533 (US$ 2,158 as of December 31, 2024).

14.3. Contingent liabilities

The estimates of contingent liabilities are indexed to inflation and updated by applicable interest rates. As of September 30, 2025, estimated contingent liabilities for which the possibility of loss is classified as possible are set out in the following table:

(Expressed in millions of US Dollars, unless otherwise indicated)

Nature	09.30.2025	12.31.2024

Civil	15,124	10,910
Environmental and others	1,565	1,298
Total	41,385	39,980

The main contingent liabilities are:

· Tax matters comprising: (i) income from foreign subsidiaries and associates not included in the computation of taxable income (IRPJ and CSLL); (ii) disapproval of PIS and COFINS tax compensation due to credit disallowance; (iii) collection of PIS and COFINS, resulting from the payment of taxes negotiated with the Brazilian Federal Government, excluding the payment of fines; (iv) incidence of social security contributions on the payment of bonuses; (v) collection of ICMS involving several states; and (vi) withholding income tax (IRRF) on remittances for payments of vessel charters.

· Labor matters, comprising several labor claims;

· Civil matters comprising mainly: (i) administrative and legal proceedings challenging an ANP order requiring Petrobras to pay additional special participation fees and royalties (production taxes) with respect to several oil fields, including unitization of deposits and reservoirs; (ii) lawsuits related to contracts; (iii) claims that discuss topics related to pension plans managed by Petros; (iv) fines from regulatory agencies, mainly ANP; and (v) judicial and arbitration proceedings that discuss disposal of assets carried out by Petrobras; and

· Environmental matters comprising mainly: (i) fishermen's indemnities; and (ii) indemnities for damages and fines related to the Company operations.

14.3.1. 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, which was consolidated in Theme 13 of the TST's Repetitive Appeals. The Brazilian 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. In April 2025, the TST, accepting the STF's decision, declared the aforementioned Theme 13 to be obsolete, revoking it.

As there are several legal actions at different procedural stages, the Company monitors the application of the precedent to the respective processes, whose expectations have been changed or terminated, according to their progress in Court. In the third quarter of 2025, there was a final decision in favor of the Company, relating to the claim of the Norte Fluminense Union, which reduced this contingent liability, in the amount of US$ 5,655 (R$ 30,077 million). The Company has been reassessing the loss expectation of individual lawsuits.

As of September 30, 2025, the balance of provisions for legal proceedings regarding RMNR amounts to US$ 47 (US$ 88 as of December 31, 2024), while the contingent liabilities amount to US$ 89 (US$ 4,934 as of December 31, 2024).

14.4. Class action and related proceedings

14.4.1. 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.

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

PETROBRAS

(Expressed in millions of US Dollars, unless otherwise indicated)

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 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, 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 against the ruling and previous interim decisions. 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 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 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 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.

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 STF.

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

14.4.2. 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 September 10, 2025, the Association filed an appeal against the ruling dismissing the criminal action, which is still pending judgment. 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 before the Commercial Court, on March 25, 2025, the 1st instance of the Argentine Court closed the action because it considered that there was no relevant fact that should be reported under local legislation. As there was no appeal, the decision became final.

14.4.3. 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 became 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.

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.

On March 7, 2025, Petrobras and EIG entered into an agreement to end litigation between the parties. Under the terms of this agreement, Petrobras paid EIG the amount of US$ 283, while EIG requested the termination of the lawsuit pending in the District Court of Columbia and the cancellation of the precautionary measure blocking the Company's assets in the Netherlands, as well as waived any rights related to the dispute. Therefore, there is no further legal dispute between the parties regarding this matter.

This agreement does not constitute admission of guilt or wrongdoing by Petrobras and meets the best interests of the Company and its shareholders, considering the US legislation applicable to the trial of the case, as well as the procedural stage and characteristics of litigations in the Federal Courts of the United States.

14.4.4. Arbitrations proposed by non-controlling shareholders in Brazil

There were no relevant changes in the nine-month period ended September 30, 2025.

The Company annually tests its assets for impairment or when there is an indication that their carrying amount may not be recoverable, or that there may be a reversal of impairment losses recognized in previous years. In the nine-month period ended September 30, 2025, net impairment losses were recognized in the amount of US$ 156, mainly due to:

· the economic unfeasibility of blocks C-M-753 and C-M-789, located in the Campos basin, which resulted in the recognition of a US$ 208 impairment loss;

· the contract amendment for the lease of FPSO Cidade de Santos (Uruguá CGU), due to the need to extend the contractual term until the end of 2026 for the decommissioning of this asset, which resulted in the recognition of a US$ 83 impairment loss;

· the additional financial compensation for the Cherne Cluster, due to the accident on platform PCH-1, occurred in the second quarter of 2025, which resulted in the recognition of a US$ 57 impairment loss;

· the Company assessed the recoverability of the refining and utility assets of the Boaventura Energy Complex upon the approval of the project in August 2025 and the signing of the main contracts required for the completion and integration of these assets with the Duque de Caxias Refinery (Reduc) and, consequently, with Petrobras' set of refining and logistics assets. In the recoverability assessment of these assets, a US$ 328 impairment reversal was recognized in the CGUs Boaventura Energy Complex – Refining and Utilities, mainly considering the fair value less costs of disposal of the refining assets, categorized within level 3 of the fair value hierarchy, estimated using the present value method, and adopting a discount rate of 8.1%. From that point forward, the refining and utility assets of the Boaventura Energy Complex will be included in the UGC set of refining and logistics and will have their recoverable amounts tested as a group; and

· an incident involving the oxygen compressor at Araucária Nitrogenados S.A. (ANSA), causing a delay in the resumption of operations and the recognition a US$ 41 impairment loss.

In the nine-month period ended September 30, 2024 net impairment losses were recognized in the amount of US$ 163, mainly due to: (i) the assessment of the economic unfeasibility of exploratory assets located in the Campos basin (blocks C-M-657 and C-M-709) in the amount US$ 224; (ii) a US$ 37 impairment reversal of property, plant and equipment after management approval of the return of the operational activities of the fertilizer plant ANSA; (iii) a US$ 13 impairment reversal of property, plant and equipment following the increase of the occupied area of building Torre Pituba; and (iv) a US$ 12 impairment reversal of equity-accounted investments, following the approval for the sale of the Company’s 18% interest in the share capital of UEG Araucária S.A., resulting in the reclassification of this equity-accounted investment to assets classified as held for sale and its registration at fair value less costs of disposal.

(1) Petrobras' ADSs are equivalent to two 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. 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, whose shares were cancelled in January 2025, as described in note 25.1.

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.

26. Financial risk management

The Company is exposed to a variety of risks arising from its operations, such as price risk (related to crude oil and oil products prices), foreign exchange rates risk, interest rates risk, credit risk and liquidity risk. Corporate risk management is part of the Company’s commitment to act ethically and comply with the legal and regulatory requirements of the countries where it operates.

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.

a) Cash flow hedge involving the Company’s future 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 September 30, 2025, 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$ 5.3186 exchange rate are set out below:

		Present value of hedging instrument notional value at 09.30.2025
Hedging Instrument	Hedged Transactions	Nature of the Risk	Maturity Date	US$ million	R$ million

Nominal value of hedging instrument (finance debt and lease liability) at September 30, 2025	92,848	493,820

In the nine-month period ended September 30, 2025, the Company recognized a US$ 150 gain, within foreign exchange rate gains (losses), due to ineffectiveness (a US$ 92 loss in the same period of 2024).

The average ratio of future exports for which cash flow hedge accounting was designated to the highly probable future exports is 78.68%.

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

Other comprehensive income (loss)	11,764	(5,279)
Closing balance	(19,081)	(23,489)

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 2025-2029, 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 September 30, 2025, is set out below:

	2025	2026	2027	2028	2029	2030 onwards	Total
Expected realization	(1,562)	(5,581)	(5,947)	(3,762)	(3,299)	1,070	(19,081)

b) Derivative financial instruments not designated for hedge accounting

In September 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 537 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:

Financial Instruments	Reasonably possible scenario
Swap CDI x USD		(12)

c) Sensitivity analysis for foreign exchange rate 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 4.91% depreciation of the real;

· euro x U.S. dollar - a 3.12% appreciation of the euro;

· pound sterling x U.S. dollar - a 1.89% appreciation of the pound sterling;

· renminbi x U.S. dollar – a 1.14 % appreciation of the renminbi.

26.4.2. 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 September 30, 2025. 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.

The positions with commodity derivatives are presented in note 26.3.

26.4.3. Interest rate risk management

The Company considers that interest rate risk does not create 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.

26.5. 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 business plan.

Management believes that its current working capital is sufficient for the Company's present requirements. In the event that the Company presents negative net working capital, management believes it does not compromise the Company's liquidity since Petrobras maintains revolving credit facilities contracted as a liquidity reserve to be used in adverse scenarios (see note 23.5).

Additionally, the Company regularly assesses market conditions and may enter into transactions to repurchase its own securities or those of its subsidiaries, through a variety of means, including tender offers, make whole exercises and open market repurchases, since they are in line with the Company's liability management strategy, in order to improve its debt repayment profile and cost of debt.

The expected cash flows of finance debt and lease liabilities are presented in notes 23.4 and 24, respectively.

26.6. Credit 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 September 30, 2025, the financial assets of cash and cash equivalents and of marketable securities 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.

27. 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.

The total compensation concerning these members was US$ 177 thousand for the nine-month period ended September 30, 2025 (US$ 209 thousand with tax and social security costs). For the same period of 2024, the total compensation concerning these members was US$ 203 thousand (US$ 241 thousand with tax and social security costs).

On April 16, 2025, the Company’s Annual Shareholders’ Meeting set the threshold for the overall compensation for executive officers and board members at US$ 8.3, R$ 47.57 million, from April 2025 to March 2026 (US$ 8.6, R$ 43.21 million, from April 2024 to March 2025, as approved on April 25, 2024).

Report of Independent Registered Public Accounting Firm

To Shareholders and Board of Directors of

Petróleo Brasileiro S.A. – Petrobras

Rio de Janeiro - RJ

Results of Review of Condensed Consolidated Interim Financial Statements

We have reviewed the condensed consolidated statement of financial position of Petróleo Brasileiro S.A. - Petrobras and subsidiaries (the “Company”) as of September 30, 2025, the related condensed consolidated statements of income and comprehensive income for the three and nine-month periods ended September 30, 2025 and 2024, the related condensed consolidated statements of changes in shareholders’ equity and cash flows for the nine-month period ended September 30, 2025 and 2024, and the related notes (collectively, the condensed consolidated interim financial statements). Based on our review, we are not aware of any material modifications that should be made to the condensed consolidated interim financial statements for them to be in accordance with IAS 34 - Interim Financial Reporting, as issued by the International Accounting Standards Board (IASB).

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statement of financial position of the Company as of December 31, 2024, and the related consolidated statements of income, comprehensive income, changes in shareholders’ equity, and cash flows for the year then ended (not presented herein); and in our report dated April 3, 2025, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated statement of financial position as of December 31, 2024, is fairly stated, in all material respects, in relation to the consolidated statement of financial position from which it has been derived.

Basis for Review Results

These condensed consolidated interim financial statements are the responsibility of the Company’s management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

 54

We conducted our reviews in accordance with the standards of the PCAOB. A review of condensed consolidated interim financial statements consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.
