Report of independent registered

To the shareholders and Board of Directors of

Vale S.A.

Results of review of interim
financial statements

We have reviewed the accompanying condensed consolidated interim statement of financial position of Vale S.A. and its subsidiaries (the "Company") as of September 30, 2025, and the related condensed consolidated interim income statement and statement of comprehensive income for the three-month and nine-month periods ended September 30, 2025 and September 30, 2024 and the condensed consolidated interim statements of changes in equity and cash flows for the nine-month periods ended September 30, 2025 and September 30, 2024, including the related notes (collectively referred to as the "interim financial statements"). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial statements for them to be in conformity 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), the consolidated statement of financial position of the Company as of December 31, 2024, and the related consolidated income statement, statement of comprehensive income, statement of changes in equity and statement of cash flows for the year then ended (not presented herein), and in our report dated February 19, 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 interim financial statements are the responsibility of the Company's management. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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. We conducted our review in accordance with the standards of the PCAOB. A review of 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.

2. Basis of preparation of condensed consolidated interim financial statements

The condensed consolidated interim financial statements of the Company (“interim financial statements”) have been prepared and are being presented in accordance with IAS 34 - Interim Financial Reporting, as issued by the International Accounting Standards Board (“IASB”). All material information for the interim financial statements, and only this information, are presented and consistent to those used by the Company's Management.

	9
Notes to the Consolidated Interim Financial Statements<br><br>Expressed in millions of United States dollar, unless otherwise stated
---

The interim financial statements have been prepared to update users on the relevant events and transactions that occurred in the period and must be read together with the financial statements for the year ended December 31, 2024. All accounting policies, accounting estimates and judgments, risk management and measurement methods are the same as those adopted in the preparation of the latest annual financial statements.

These interim financial statements were authorized for issue by the Board of Directors on October 30, 2025.

a) Functional currency and presentation currency

The interim financial statements of the Company and its associates and joint ventures are measured using the currency of the primary economic environment in which each entity operates (“functional currency”), in the case of the Parent Company it is the Brazilian real (“R$”). For presentation purposes, these interim financial statements are presented in the United States dollars (“US$”) as the Company believes that this is how international investors analyze the financial statements.

The main exchange rates used by the Company to translate its foreign operations are as follows:

			Average<br>rate
	Closing<br>rate		Three-month<br>period ended September 30,		Nine-month<br>period ended<br><br>September<br>30,
	September<br>30, 2025	December<br>31, 2024	2025	2024	2025	2024
US<br>Dollar ("US$")	5.3186	6.1923	5.4488	5.5454	5.6502	5.2445
Canadian<br>dollar ("CAD")	3.8186	4.3047	3.9574	4.0660	4.0413	3.8549
Euro<br>("EUR")	6.2414	6.4363	6.3679	6.0918	6.3188	5.7036

b) Tariffs applied by the United States of America

The Company is subject to external risk factors related to its operations and its customer portfolio and supply chain profile.

In February 2025, the President of the United States of America ("USA") signed an executive order imposing tariffs on products from several countries. The program establishes country-specific import tariffs, based on a minimum rate of 10%, a level at which Brazil was set.

In July 2025, the U.S. government issued an executive order that added a 40% tariff on top of the existing 10% rate applied to Brazil. However, this new 40% tariff was partially waived for various imports, including products exported by Vale to the U.S. market. Although the Company's sales to USA are not relevant, Vale is monitoring developments and, until this date the Company does not expect any significant effects on its operations or cash flows.

3. Significant events and transactions related to the three-month period ended September 30, 2025

•	Participative shareholders’<br>debentures – In October 2025 (subsequent<br>event), Vale approved the proposal for the optional acquisition of up to all of the outstanding participative shareholders’ debentures.<br>The deadline for the debentures holders to manifest their sale intentions will close on October 31, 2025. Further details are presented<br>in note 20 of these interim financial statements.
•	Divestment of Aliança<br>Geração de Energia S.A. (“Aliança”) – In<br>September 2025, the Company completed the sale of a 70% stake in Aliança to Global Infrastructure Partners (“GIP”)<br>for US$871. As a result, Aliança became an associate, and Vale recognized a loss of US$89 in the income statement for the three-month<br>period ended September 30, 2025, as “Impairment and gains (losses) on disposal of non-current assets, net”. Further details<br>are presented in note 15(a) to these interim financial statements.
---	---
•	Shareholder remuneration<br>– In July 2025, the Board of Directors<br>approved shareholder remuneration in the amount of US$1,448 (R$8,091 million), which was paid in September 2025. Further details are presented<br>in note 28(c) of these interim financial statements.

7. Taxes

In December 2021, the Organization for Economic Co-operation and Development (“OECD”) released the Pillar Two model rules to reform international corporate taxation. Multinational economic groups within the scope of these rules are required to calculate their effective tax rate in each country where they operate, the “GloBE effective tax rate”.

When the effective GloBE rate of any entity in the economic group, aggregated by jurisdiction where the group operates, is lower than the minimum rate defined at 15%, the multinational group must pay a supplementary amount of tax on profit, referring to the difference between its rate effective GloBE and the minimum tax rate.

The Company is subject to OECD Pillar Two model rules in Australia, Brazil, Canada, Indonesia, Japan, Luxembourg, Malaysia, Netherlands, Singapore, Switzerland and United Kingdom. Therefore, the impacts from Pilar Two are already being considered on the calculation of income tax for these jurisdictions.

However, the Company does not expect material impacts on the calculation of income tax or on the financial statements for the current and future periods, from the application of the Pillar Two rules currently in effect.

The Company applied the relief from the requirement to recognize and disclose deferred taxes arising from enacted or substantively enacted tax law that implements the Pillar Two model rule, according to IAS 12 – Income taxes.

a) Income tax reconciliation

Income tax expense is recognized based on the estimate of the weighted average effective tax rate expected for the full year, adjusted for the tax effect of certain items that are recognized in full on the interim tax calculation. Therefore, the effective tax rate in the interim financial statements may differ from management’s estimate of the effective tax rate for the year. The reconciliation of the taxes calculated according to the nominal tax rates and the amount of taxes recorded is shown below:

Provisionally priced commodities sales - The Company is mainly exposed to iron ore and copper price risk. The determination of the final sales price for these commodities is based on the pricing period outlined in the sales contracts, typically occurring after the revenue recognition date. Consequently, the Company initially recognizes revenue using a provisional invoice. Subsequently, the receivables associated with provisionally priced products are measured at fair value through profit or loss (note 19). Any fluctuations in the value of these receivables are reflected in the Company's net operating revenue.

The sensitivity of the Company’s risk related to the final settlement of provisionally priced accounts receivable is detailed below:

The financial liabilities presented as Suppliers and contractors in the Company's statement of financial position represent the outstanding balance of invoices with suppliers for purchases of goods and services, being the average due date usually approximately 60 days.

The Company enters into supplier finance arrangements ("Arrangements") as part of the working capital strategy used in the Company's usual operating cycle, being the payment term extension limited to a short-term period. The Company is also party in agreements structured so that certain suppliers can advance their receivables with Vale due to purchases of materials and services, without any type of change in value or payment terms for the Company. These supplier finance arrangements continue to be presented as suppliers in the Company's statement of financial position, as the terms and conditions of the original liabilities were not substantially modified. The carrying amount related to these transactions is shown below:

	September 30, 2025	December 31, 2024
Carrying amount of accounts payable included in the Arrangements of which suppliers have already received payment	1,346	1,343
Carrying amount of accounts payable included in the Arrangements of which suppliers have not yet received payment	–	6
Total carrying amount relating to Arrangements with suppliers and contractors	1,346	1,349

Financial charges related to the increase in payment terms are recognized in the financial results as interest on supplier finance arrangements (note 6). The financial charges recognized in the income statement for the nine-month period ended September 30, 2025 and 2024 due to the Arrangements totaled, respectively, US$96 and US$131.

In December 2020, the Company entered into an agreement with the Federal Government to continue operating its concessions of the Estrada de Ferro Carajás (“EFC”) and Estrada de Ferro Vitória a Minas (“EFVM”) for thirty years more, extending the maturity date from 2027 to 2057.

Later, in January 2024, responding to a request from the Ministry of Transportation, Vale, the National Land Transport Agency (“ANTT”), and the Brazilian Federal Government, resumed discussions on the general conditions for concession contracts and on December 30, 2024, the general basis for the renegotiation were agreed, aiming to promote the modernization and update of the existing contracts. This process was subject to evaluation and approval by the competent authorities, and its conformation would occur through a consensual solution discussed with the bodies involved at the Brazilian Federal Accounts Court.

As part of these general bases, Vale committed to a maximum global contribution of approximately US$1,809, for the EFC and EFVM’s asset base review, the optimization of contractual obligations and investments replanning.

As a consequence of the new conditions of the general bases, the Company recognized, on December 31, 2024, an addition of US$256 in provision, which reflected the revised estimates regarding the amount of future disbursements required to fulfill the new contractual obligations of the railway concessions. Additionally, the liability was reduced by US$656 due to the advanced payment made by Vale, ahead of the previously planned cash flow.

However, on August 28, 2025, within the context of the consensual solution conducted by the Brazilian Federal Accounts Court, the parties were unable to reach consensus within the established deadline.

Despite ongoing discussions, the concession contracts remain in effect, the Company continues to comply with the established obligations, and remains committed to the general terms defined in the agreement signed on December 30, 2024. The Company believes its provisions remain sufficient to comply with the obligations related to the concessions; therefore, no revision was made in its balances.

a) Divestment of Aliança Geração de Energia S.A. (“Aliança”) – In March 2024, the Company entered into an agreement with Cemig GT to acquire its 45% stake in Aliança. The decision was taken in the context of the divestment plan announced to the market by Cemig GT in 2020, and Vale chose to exercise its preferential right of acquisition.

In August 2024, the transaction was completed for the amount of US$493 (R$2,737 million), and Vale became the sole owner of Aliança. As a result, the Company recorded a gain of US$305 in the income statement for the three-month period ended September 30, 2024 as “Results from investments and other results in associates and joint ventures,” due to the remeasurement to fair value of the previously held equity interest.

The fair value of the identifiable assets acquired and liabilities assumed as a result of the acquisition are presented below:

In March 2025, the Company signed a binding agreement with Global Infrastructure Partners (“GIP”) for the sale of 70% of its stake in Aliança and the energy assets of Sol do Cerrado solar plant and Risoleta Neves hydroelectric plant.

As a result, the related assets and liabilities were classified as held for sale and Vale recognized an impairment loss in the amount of US$117 in the income statement for the three-month period ended March 31, 2025 as "Impairment and gains (losses) on disposal of non-current assets, net", which was allocated to the goodwill (note 16) arising from the acquisition of Aliança.

In September 2025, the energy assets of Sol do Cerrado solar plant and Risoleta Neves hydroelectric plant were transferred from Vale S.A. to Aliança and, the Company concluded the transaction for the amount of US$871, comprised by a cash inflow of US$1,006, net of a reduction of US$135 in the remaining investment in Aliança due to a loan assumed by the investee in the context of the transaction.

As a result of the transaction, Vale recognized a loss of US$89 in the income statement for the three-month period ended September 30, 2025 as "Impairment and gains (losses) on disposal of non-current assets, net", and lost control over Aliança. Consequently, the Company will no longer consolidate Aliança, with the remaining interest accounted for as an associate by the equity method.

The effects of this transaction are summarized below:

	September, 2025
Cash received	1,006
Fair value of 30% interest retained	238
(-) Derecognition of Aliança’s net assets	(1,333)
Loss on the transaction	(89)

b) Divestment on Vale Oman Distribution Center (“VODC”) – In August 2024, the Company established a joint venture with AP Oryx Holdings LLC (“Apollo”) through a binding agreement to sell 50% equity interest in VODC for US$600 million. The transaction was completed in September 2024, reducing Vale’s stake in VODC from 100% to 50% and changing its status from a subsidiary to a joint venture.

With this transaction, Vale shared control over VODC with Apollo and, from then on, will no longer consolidate VODC, which will be accounted for as a joint venture using the equity method.

As a result of the transaction, the Company recognized a gain of US$1,222 in the income statement as “Other operating expenses, net”. This gain is due to (i) the result of the sale of the equity interest in the amount of US$555, (ii) the result of the remeasurement to fair value of the remaining interest in the amount of US$555, and (iii) the reclassification to income statement of the cumulative translation adjustments in the amount of US$112. The effects of this transaction are summarized below:

	September<br>26, 2024
Sale<br>of the 50% equity interest
Cash<br>received	600
Derecognition<br>of VODC’s net assets	(45)

c) Divestment on PT Vale Indonesia Tbk (“PTVI”) – In June 2024, the Company reduced its interests in PTVI in approximately 10.5%. This divestment was carried out through (i) the issuance of PTVI’s new shares, thereby diluting Vale in 2.1%, and (ii) by the direct sale of 8.4% of Vale’s shares to MIND ID. As a result of the transaction, MIND ID became PTVI's largest shareholder, holding approximately 34.0% of the issued shares, with the Company and SMM holding approximately 33.9% and 11.5%, respectively. The completion of the transaction satisfied a key condition for PTVI to extend its mining license until 2035, with potential extension beyond this period subject to certain requirements.

With the transaction, Vale received US$155 for its shares and lost control over PTVI, which was accounted for as an associate under the equity method due to the significant influence retained by Vale over PTVI.

As result, in June 2024, the Company recognized a gain of US$1,059 in the income statement as "Other operating expenses, net". This gain was due to the reclassification of cumulative translation adjustments of US$1,063 and the gain on remeasurement of the interest retained at fair value of the US$657, net of the loss on the reduction in PTVI stake in the amount of US$661. The effects of this transaction are summarized below:

	June 28, 2024
Cash consideration received	155
Fair value of 33.9% interest retained (i)	1,910
Effects of the deconsolidation:
Derecognition of net assets of PTVI	(3,697)
Gain on derecognition of noncontrolling shareholders	1,628
Gain on the reclassification of cumulative translation adjustments	1,063
Gain on the transaction recorded in the income statement	1,059

(i) The fair value of the 33.9% retained interest was estimated based on a third-party valuation report. The valuation considered the discounted cash flow method. The key assumptions considered were (i) discount rate of 7.75% with incremental risk premium of around 1.00% on certain assets, (ii) asset life through to 2065, and (iii) range of expected nickel prices from US$/t 17,501 to US$/t 21,000.

d) Strategic partnership in the Energy Transition Metals business – In April 2024, the Company concluded the transaction with Manara Minerals to sell 10% of the business for US$2,455, which was fully contributed to VBM thereby diluting Vale to a 90% equity interest, retaining control over VBM. As a result, Vale recognized a gain from the sale in the amount of US$895, of which US$1,514 was attributable to noncontrolling interests recorded in the equity as "Transactions with noncontrolling interests".

23. Brumadinho dam failure

In January 2019, a tailings dam (“Dam I”) experienced a failure at the Córrego do Feijão mine, in the city of Brumadinho, state of Minas Gerais, Brazil. The failure released a flow of tailings debris, destroying some of Vale’s facilities, affecting local communities and disturbing the environment. The tailings released have caused an impact of around 315 km in extension, reaching the nearby Paraopeba River. The dam failure in Brumadinho (“event”) resulted in 270 fatalities or presumed fatalities, including two pregnant women, and caused extensive property and environmental damage in the region.

As a result of the dam failure, the Company recognized provisions to meet its assumed obligations, including indemnification to those affected by the event, remediation of the impacted areas and compensation to the society. In addition, the Company has incurred expenses, which have been recognized straight to the income statement, in relation to tailings management, communication services, humanitarian assistance, payroll, legal services, water supply, among others.

Judicial Settlement for Integral Reparation
---

On February 4, 2021, the Company entered into a Judicial Settlement for Integral Reparation (“Global Settlement”), which was under negotiations since 2019, with the State of Minas Gerais, the Public Defender of the State of Minas Gerais and the Federal and the State of Minas Gerais Public Prosecutors Offices, to repair the environmental and social damage resulting from the Dam I rupture. As a result of the Global Settlement, the requests for the reparation of socioenvironmental and socioeconomic damages caused by the dam failure were substantially resolved.

The Global Settlement includes: (i) payment obligations, of which the funds will be used directly by the State of Minas Gerais and Institutions of Justice for socioeconomic and socioenvironmental compensation projects; (ii) socioeconomic projects in Brumadinho and other municipalities; and (iii) compensation of the environmental damage caused by the dam failure. These obligations are projected for an average period of 5 years.

In addition, the Global Settlement addresses the diffuse and collective socioeconomic damages resulting from the disaster, with the exception of supervening damages, individual damages and homogeneous individual damages of a divisible nature, in accordance with the claims of the lawsuits not extinguished by the Global Settlement.

For the measures described in items (i) and (ii), the amounts are specified in the Global Settlement. For the execution of the environmental recovery, actions have no cap limit, despite having been estimated in the Global Settlement due to the Company's legal obligation to fully repair the environmental damage caused by the dam failure. Therefore, although Vale is monitoring this provision, the amount recorded could materially change depending on several factors that are not under the Company’s control.

Other obligations

The Company is also working to ensure geotechnical safety of the remaining structures at the Córrego do Feijão mine, in Brumadinho, and the removal and proper disposal of the tailings of Dam I, including dredging part of the released material and de-sanding from the channel of the river Paraopeba.

For the individual indemnification, Vale and the Public Defendants of the State of Minas Gerais formalized an agreement on April 5, 2019, under which those affected by the Brumadinho’s dam failure may join an individual or family group out-of-court settlement agreements for the indemnification of material, economic and moral damages. This agreement establishes the basis for a wide range of indemnification payments, which were defined according to the best practices and case law of Brazilian Courts, following rules and principles of the United Nations.

a) Legal Proceedings

Class action in the United States

Vale is defending itself against a class action brought before a Federal Court in New York and filed by holders of securities - American Depositary Receipts ("ADRs") - issued by Vale.

In August 2024, the Court held a hearing to consider Vale's Motion for Class Decertification, as well as the parties' Cross Motions to Exclude Expert. A decision from the Court is currently pending.

In November 2021, a new complaint was filed by eight investment funds that chose to seek redress for alleged damages independently and separately from the class members of the main action, with the same allegations presented in the main class action. A decision from the Court on Vale's preliminary defense ("motion to dismiss") has been pending since December 2023.

The likelihood of loss of these proceedings is considered possible. However, considering the current phase of these lawsuits, it is not yet possible to reliably estimate the amount of a potential loss. The amount of damages sought in these claims is unspecified.

Arbitration proceedings in Brazil filed by shareholders, a class association and foreign investment funds
---

In Brazil, Vale is a defendant in one arbitration filed by 385 minority shareholders and three arbitrations filed by foreign investment funds. Vale was also a defendant in two arbitrations filed by a class association allegedly representing all Vale’s noncontrolling shareholders, which were dismissed in August 2024.

In the four ongoing proceedings, the claimants argue that Vale was aware of the risks associated with the dam and failed to disclose it to its shareholders. Based on such argument, they claim compensation for losses caused by the decrease in share price.

The expectation of loss is classified as possible for the four procedures and, considering the initial phase, it is not possible at this time to reliably estimate the amount of a possible loss.

In one of the proceedings filed by foreign legal entities, the Claimants initially estimated the amount of the alleged losses would be approximately US$330 (R$1,800 million), subject to interest and monetary adjustments. In another proceeding filed by foreign legal entities, the Claimants initially estimated the amount of the alleged losses would be approximately US$715 (R$3,900 million), subject to interest and monetary adjustments. In the procedure presented by minority shareholders, the applicants estimated the alleged losses at approximately US$550 (R$3,000 million), subject to interest and monetary adjustments, which could be increased later, as alleged by the applicants.

The Company disagrees with the ongoing proceedings and understands that, in this case and at the current stage of the proceedings, the probability of loss in the amount claimed by the claimants is remote.

24. Liabilities related to associates and joint ventures

In November 2015, the Fundão tailings dam owned by Samarco Mineração S.A. (“Samarco”) experienced a failure, flooding certain communities and impacting communities and the environment along the Doce River. The dam failure resulted in 19 fatalities and caused property and environmental damage to the affected areas. Samarco is a joint venture equally owned by Vale S.A. and BHP Billiton Brasil Ltda. (‘‘BHPB’’).

Thus, Vale, Samarco, and BHPB entered into agreements with the Federal Union, the States of Minas Gerais and Espírito Santo, and some other federal and state agencies, establishing the creation of socioenvironmental and socioeconomic programs aimed at adopting measures for mitigation, remediation, and compensation of damages. However, the requirements established reparation measures in the agreements could not be fully implemented within the established period, and the involved parties began initiated further negotiations to seek a definitive agreement for the resolution of all obligations related to the dam collapse.

a) Definitive Settlement for the full reparation

In October 2024, Vale, Samarco and BHPB, together with the Brazilian Federal Government, the State Governments of Minas Gerais and Espírito Santo, the Federal and State Public Prosecutors’ and Public Defenders’ Offices and other Brazilian public entities (jointly, “the Parties”) entered into a new agreement (“Definitive Settlement”) on integral and definitive reparation of the impacts of Fundão dam collapse, in Mariana, Minas Gerais. The agreement was ratified in November 2024.

The Definitive Settlement replaced all of the previously signed agreements and addressed Brazilian public authorities the claims related to the Fundão dam collapse, from the perspective of socioenvironmental and socioeconomical damages.

	37
Notes to the Consolidated Interim Financial Statements<br><br>Expressed in millions of United States dollar, unless otherwise stated
---

The total amount of the Definitive Settlement is US$31.7 billion (R$170 billion), comprising past and future obligations, to serve the people, communities and environment impacted by the dam failure. It includes:

•	US$7.9<br>billion (R$38 billion) already incurred, from the date of the dam collapse until the Definitive Settlement, by Vale, Samarco and BHPB<br>with remediation and compensation measures and, therefore, do not constitute the Company’s provision balance;
•	US$18 billion (R$100<br>billion) paid over 20 years to the Federal Government, the States of Minas Gerais and Espírito Santo, the municipalities and which<br>will also be used by Justice Institutions, to fund compensatory actions tied to public policies; and
---	---
•	US$5.8<br>billion (R$32 billion) in performance obligations executed by Samarco, including initiatives for individual indemnification, resettlement,<br>and environmental recovery. The expectation is that the cash disbursement related to these obligations will occur substantially over the<br>next 3 years.
---	---

Samarco has primary responsibility for funding the obligations related to the Definitive Settlement. Vale and BHPB have secondary funding obligations in the proportion to their 50 per cent shareholding in Samarco, in extent to which Samarco may not be able to fund the future cash outflows.

The judicial ratification of the Definitive Settlement ended a series of relevant lawsuits, moved in Brazil. Vale, jointly with BHPB and Samarco, is requiring the archive of these proceedings.

b) Provision related to the Samarco dam failure

The Company recognized an addition to the provision in the amount of US$182 in the nine-month period ended September 30, 2025, substantially related to a revision on the costs to complete individual indemnification programs. The changes on the provision are presented below:

	Total
Balance<br>as of December 31, 2024	3,663
Changes<br>in estimates	182
Monetary<br>and present value adjustments	153
Disbursements	(2,122)
Translation<br>adjustments	525
Balance<br>as of September 30, 2025	2,401

The cash outflows to meet the obligations are discounted to present value at an annual rate in real terms, which decreased from 7.30% on December 31, 2024, to 7.18% on September 30, 2025.

c) Remaining legal proceedings

With the Definitive Agreement, the public civil actions brought by the Brazilian Justice Institutions and Brazilian public authorities were substantially resolved and the parameters for compliance with the reparation and compensation for damages were defined. Thus, the remaining most relevant legal proceedings are shown below:

Claims in the United Kingdom and the Netherlands

In July 2024, Vale and BHP have entered into a confidential agreement without any admission of liability pursuant to Vale and BHP will share equally any potential payment obligations arising from the UK and Dutch Claims, described below.

London claim - As a result of the rupture of Samarco’s Fundão dam failure, BHP Group Ltd (“BHP”) was named as defendant in group action claims for damages filed in the courts of England and Wales for various plaintiffs, between individuals, companies and municipalities from Brazil that were supposedly affected by the Samarco dam failure (the “UK Claim”).

The proceedings against BHP are still progressing in London and the oral testimony phase of the first stage of the trial, in which the liability issues of the BHP group companies are dealt with, took place between October 2024 and March 2025. If BHP's liability is confirmed, a second stage trial will be held to discuss and determine the amount of damages, scheduled to begin in October 2026 and is expected to last 22 weeks. On the first week of July, it was held a case management conference in anticipation of a possible 2nd stage trial. BHP’s deadline for submitting a complementation of its response is currently ongoing.

The likelihood of loss of these proceedings is considered possible. However, considering the current phase, it is not yet possible to reliably estimate the amount of a potential loss, and an estimate may become quantifiable as the case progresses.

Netherlands proceeding - In March 2024, a court in Amsterdam granted a preliminary injunction freezing the shares in Vale Holdings B.V., a wholly owned subsidiary incorporated in the Netherlands, and the economic rights attached to those shares, in guarantee of an amount of approximately US$1,124 (EUR955 million). The freezing orders were issued in anticipation of a legal action to be brought against Vale by certain Brazilian municipalities and an organization that represents individuals and small businesses that claim to have been affected by the collapse of Samarco’s Fundão dam in 2015. With the adherence of three municipalities (Iapu, Ponte Nova and Rio Casca) to the Definitive Settlement, their lawsuit was discontinued, with the attachment being reduced to US$877 (EUR745.4 million). In July 2025, a case management conference was held to establish the procedural timeline. The Court has decided that the proceedings will be divided into 3 stages: (i) for the exam of the Court’s jurisdiction on the case; (ii) if accepted the jurisdiction, the general exam of the companies’ liability defenses, (iii) if accepted the companies’ liability, a third stage trial will be held to assess the individual damages of the claimants. Vale’s deadline is currently ongoing to present its jurisdiction application, and a hearing is expected to be held in 2026.

The likelihood of loss of these proceedings is considered possible. However, considering the initial phase, it is not yet possible to reliably estimate the amount of a potential loss, and an estimate may become quantifiable as the case progresses.

d) Judicial reorganization of Samarco

In April 2021, Samarco filed for Judicial Reorganization (“JR”) with the Courts of Minas Gerais to renegotiate its debt, which was held by bondholders abroad. The purpose of JR was to restructure Samarco’s debts and establish an independent and sustainable financial position, allowing Samarco to keep working to resume its operations safely and to fulfill its obligations for mitigation, remediation, and compensation of damages.

In May 2023, Vale S.A. entered into a binding agreement jointly with BHPB, Samarco and certain creditors which hold together more than 50% of Samarco's debt, setting the parameters of Samarco’s debt restructuring to be implemented through a consensual restructuring plan, which was approved by the creditors, submitted to the JR Court in July 2023, and confirmed by the judge in September 2023.

In December 2023, Samarco’s existing US$4.8 billion financial debt held by creditors was exchanged for approximately US$3.9 billion of long-term unsecured debt, bearing interest from 2023 to 2031.

After the execution of the plan, Samarco has a lean capital structure, in line with its operational ramp-up and cash flow generation. The plan considers the fund for the reparation and compensation programs capped at US$1 billion from 2024 to 2030, of which US$365 has already been incurred, and additional contributions after that period due to the Samarco’s projected cash flows generation.

In August 2025, Samarco's judicial reorganization process was concluded by decision of the 2nd Business Court of the District of Belo Horizonte, with a favorable opinion from the Public Prosecutor's Office of the State of Minas Gerais, which concluded that the judicial reorganization had fulfilled its purpose. Samarco will continue to comply with the remaining obligations, in accordance with the terms and deadlines established.

25. Provision for de-characterization of dam structures and asset retirement obligations

The Company is subject to local laws and regulations, that require the decommissioning of the assets that Vale operates at the end of their useful lives, therefore, expenses related to the demobilization occur after the end of operational activities and throughout the life of operations through progressive closures. These obligations are regulated in Brazil at the Federal and State levels by ANM (National Mining Agency) and Environmental Agencies, respectively. Among the requirements, the closure plans must consider the physical, chemical and biological stability of the areas and post-closure actions for the period necessary to verify the effectiveness of the decommissioning. These obligations are accrued and are subject to critical estimates and assumptions applied to the measurement of costs by the Company. Depending on the geotechnical characteristics of the structures, the Company is required to de-characterize the structures, as shown in item a) below.

(i) The cash flow for de-characterization projects are estimated for a period up to 13 years and were discounted to present value at an annual rate in real terms, which decreased from 7.36% to 7.34%.

a) De-characterization of upstream geotechnical structures

As a result of the Brumadinho dam failure (note 23) and, in compliance with laws and regulations, the Company has decided to accelerate the plan to “de-characterize” of all its dams and dikes built under the upstream method, located in Brazil. These structures are in different stages of maturity of engineering projects, for which the estimate of expenditures includes in its methodology a high degree of uncertainty in the definition of the total cost of the project in accordance with best market practices.

The Company also operates tailings dams in Canada, including upstream compacted dams. However, the Company decided that these dams will be decommissioned using other methods, thus, the provision to carry out the decommissioning of dams in Canada is recognized as “Obligations for decommissioning assets and environmental obligations”, as presented in item (b) below.

Operational stoppage and idle capacity

The Company has suspended some operations due to judicial decisions or technical analysis performed by Vale regarding the safety of its geotechnical structures located in Brazil. The Company has been recording losses in relation to the operational stoppage and idle capacity of the Iron Solutions segment in the amounts of US$10 and US$31 for the three and nine-month period ended September 30, 2025, respectively (2024: US$36 and US$108, respectively). The Company is working on legal and security to resume operations.

26. Legal proceedings

The Company is a defendant in numerous legal and administrative actions in the ordinary course of business, including civil, tax, environmental and labor proceedings.

The Company makes use of estimates to recognize the amounts and the probability of outflow of resources, based on reports and technical assessments and on management’s assessment. Provisions are recognized for probable losses of which a reliable estimate can be made.

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

The lawsuits related to Brumadinho event (note 23) and the Samarco dam failure (note 24) are presented in its specific notes to these financial statements and, therefore, are not disclosed below. In addition, the tax litigation related to income tax and social contribution is presented in note 7(d).

a) Share-based payments

For the long-term incentive programs, the Company compensation plans include Matching Program and Performance Share Unit program (“PSU”), with three-year-vesting cycles, respectively, with the aim of encouraging employee’s retention and encouraging their performance. The fair value of the programs is recognized on a straight-line basis on equity, with a corresponding entry in the income statement, over the three-year required service period, net of estimated losses. The charges related to these programs are recorded in liabilities as “Employee benefits”.

Matching Program

The fair value of the Matching program was estimated using the Company's share price and ADR and the number of shares granted on the grant date. The information by valid programs during the nine-month period ended September 31, 2025 is shown below:

	2025 Program	2024 Program	2023 Program
Granted shares	2,453,783	2,244,659	1,330,503
Share price	10.13	12.02	15.94

Performance Shares Units (“PSU”)

The fair value of the PSU program was measured by estimating the performance factor using Monte Carlo simulations for the Return to Shareholders Indicator and health and safety and sustainability indicators. The assumptions used for the Monte Carlo simulations are shown in the table below by valid program during the nine-month period ended September 30, 2025, as well as the result used to calculate the expected value of the total performance factor.

	2025 Program	2024 Program	2023 Program
