中期审查结果
基本报表

我们已审核Vale S.A.及其附属公司（以下简称「公司」）截至2024年9月30日的附属综合财务状况基本报表，以及截至2024年9月30日三个月和九个月期间、2024年9月30日及2023年9月30日结束的相关综合损益基本报表和综合收益基本报表，以及截至2024年9月30日及2023年9月30日结束的相关权益变动及现金流量的综合中期基本报表，包括相关附注（统称为「中期基本报表」）。 根据审核意见，我们未发现应对上述中期基本报表进行实质修改以符合由国际会计准则委员会（IASB）制定的IAS 34《中期财务报告》的任何重大问题。

我们曾根据美国公开公司会计监督委员会（PCAOB）的标准，对公司截至2023年12月31日的合并资产负债表以及相关合并损益表、综合损益表、权益变动表和现金流量表（未在此处呈现），进行过审计，在我们2024年2月22日的报告中，对这些合并基本报表表示无保留的意见。我们认为，附属的合并资产负债表所列的资讯截至2023年12月31日，在所有重要方面，与导出该资讯的合并资产负债表相关，是诚实表述的。

审查结果的依据

这些中期基本报表，为公司管理层负责。我们是一家在美国公开上市公司审计监督委员会（PCAOB）注册的会计师事务所，根据美国联邦证券法和证券交易委员会及PCAOB的适用法律法规，对公司必须保持独立。我们根据PCAOB的标准进行了审查。对中期基本报表的审查主要包括应用分析程序并就负责财务和会计事项的人进行询问。这种审查范围明显比按照PCAOb标准进行的审计要少，其目的是对基本报表作为整体的意见表达。因此，我们并未发表该等意见。

3. Significant events and transaction related to third quarter of 2024

4. Information by business segment and geographic area

In 2024, consistently with the reports analyzed by the executive committee and Board of Directors, the Company changed its adjusted EBITDA definition to include the “EBITDA from associates and joint ventures”, which is a measure of their “equity results” (note 14) excluding (i) net finance costs; (ii) depreciation, depletion, and amortization; (iii) taxation and (iv) impairments.

Therefore, the Company’s adjusted EBITDA is defined as operating income or loss, including the EBITDA from interests in associates and joint ventures; and excluding (i) depreciation, depletion, and amortization; and (ii) impairment and gains (losses) on disposal of non-current assets, net and other. The comparative information in these interim financial statements was revised to reflect this change in the adjusted EBITDA definition.

Additionally, as a result of the reorganization of assets and the governance established for the Energy Transition Metals segment, the “Other” segment was reorganized for a better allocation of direct effects on the Iron Ore Solutions and Energy Transition Metals businesses. These effects were allocated to each segment starting from the nine-month period ended September 30, 2024.

a) Adjusted EBITDA

(i) Includes expenses from Vale Base Metals Limited that were not allocated to the operating segment in the amounts of US$20 and US$66 for the three and nine-month period ended September 30, 2024, respectively.

(ii) Includes adjustments of US$94 and US$243 for the three and nine-month period ended September 30, 2024, respectively (2023: US$47 and US$134, respectively), to reflect the performance of the streaming transactions at market prices.

b) Net operating revenue by shipment destination

No customer individually represented 10% or more of the Company’s revenues in the periods presented above.

c) Capital expenditures by segment

(i) According to the Company's shareholders remuneration policy, minimum remuneration to Vale shareholders is calculated based on 30% of the adjusted EBITDA less sustaining capital investments.

d) Assets by geographic area

5. Costs and expenses by nature

a) Cost of goods sold, and services rendered

b)       Selling and administrative expenses

c)       Other operating revenues (expenses), net

(i) In the nine-month period ended September 30, 2024, includes the gain from the divestment in PT Vale Indonesia Tbk (note 15a) and Vale Oman Distribution Center (note 15c) in the amounts of, respectively, US$1,059 and US$1,222, and net losses on disposal of property, plant and equipment and intangible assets in the amount of US$143 (notes 16 and 17).

6. Financial results

7. Taxes

a) Income tax reconciliation

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.

From 2024, the Company is subject to OECD Pillar Two model rules in the Netherlands, Switzerland, United Kingdom, Japan, Luxembourg and Canada.

On October 3, 2024 (subsequent event), Provisional Measure No. 1,262/24 (MP) and Normative Instruction RFB No. 2,228/24 (IN) were published in Brazil to align Brazilian tax legislation with the OECD’s GloBE Rules and establish an effective minimum taxation of 15% through an additional Social Contribution on Net Profit (CSLL). The MP and the IN will come into effect from January 1, 2025, subject to a conversion of the MP into law within 120 days.

The Company does not expect material impacts on the calculation of income tax or on the financial statements for the current and future periods, notably due to the application of the simplifying rules (“Safe Harbor”) in the GloBE computation.

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:

b) Deferred income tax assets and liabilities

(i) Includes mainly the amount of US$312 related with the deferred income tax liability assumed due to the acquisition of Aliança Geração de Energia S.A. (note 15b).

The balance mainly relates to the settlement program of claims regarding the collection of income tax and social contribution on equity gains of foreign subsidiaries and associates from 2003 to 2012. This amount bears SELIC interest rate (Special System for Settlement and Custody) and will be paid in monthly installments until October 2028 and the impact of the SELIC over the liability is recorded under the Company’s financial results (note 6).

d) Uncertain tax positions (“UTP”)

The amount under discussion with the tax authorities is US$5,393 as of September 30, 2024 (December 31, 2023:US$5,408) which includes the reduction of tax losses in the amount of US$671 as of September 30, 2024 (December 31, 2023: US$754), if the tax authority does not accept the tax treatment adopted by the Company in relation to these matters.

(i) Includes the tax effects arising from the reduction of the tax losses and negative basis of the CSLL without fines and interest.

(ii) Includes the principal, without fines and interest.

(iii) Based on the assessment of its internal and external legal advisors, the Company believes that the tax treatment adopted for these matters will be accepted in decisions of the higher courts on last instance.

e) Recoverable and taxes payables

8. Basic and diluted earnings per share

The basic and diluted earnings per share are presented below:

9. Cash flows reconciliation

b) Cash flow from investing activities

c) Reconciliation of debt to cash flows arising from financing activities

Funding

Payments

d) Non-cash transactions

10. Accounts receivable

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 receivables is detailed below:

11. Inventories

(i) In the nine-month period ended September 30, 2024, the effect of provision for net realizable value was US$69 (2023: US$45).

12. Suppliers and contractors

The Company has supplier finance arrangements, which do not substantially modify the original liabilities terms and conditions and remain presented as suppliers. The outstanding balance related to those transactions was US$1,519 as of September 30, 2024 (December 31, 2023: US$1,438), of which US$231 (December 31, 2023: US$221) relates to the structure introduced by the Company with the exclusive purpose of enabling small and medium suppliers to anticipate their receivables with better interest rates, in line with Company’s social pillar.

13. Other financial assets and liabilities

a) Liabilities related to the concession grant

The Company is currently discussing with the Brazilian Ministry of Transport the general conditions for Estrada de Ferro Carajás (“EFC”) and Estrada de Ferro Vitória a Minas (“EFVM”) concessions contracts, both of which are currently being fulfilled by Vale in accordance with the contracts in place.

The potential change in the agreements is still uncertain as it is subject to conclusion of the negotiations and approval by the Company and relevant authorities. Any changes to the existing obligation will be recorded after the conclusion of the negotiations and based on the final terms agreed.

Therefore, until there is any change in the existing concession contracts, the Company will continue to comply with its obligations under the agreements, which are reflected in the Company’s liability recorded in these interim financial statements.

14. Investments in associates and joint ventures
