Classification of Companies and Entities 4.1 Type 1 - Non-Operational Wholly Owned Company (“Holding”): Company (a) in which Vale holds, directly or indirectly, all the shares and (b) which business does not involve industrial or commercial operations, having as its activity the investment as a pure holding company and/or finance and other related activities. 4.2 Type 2 - Operational Wholly Owned Company: Company (a) in which Vale holds, directly or indirectly, all the shares or all quotas if the participation is held via funds (such as venture capital) and (b) which business includes industrial, marketing and commercial activities, mineral exploration, or technology development. 4.3 Type 3 - Non-Wholly, Non-Operating Subsidiary with Third Party Participation ("Holding"): Company (a) in which Vale or company of type 1 and 2 directly or indirectly holds less than the total shareholding, (b) holds share control and (c) whose business does not involve industrial or commercial operations, having as activity investment as a pure holding company for equity interests and/or financial and other related activities. 2 of 12 Vale Group Business and Entity Management Policy DCA 011/2023 Version: 02 - 04/26/2023 POL-0043-G PUBLIC 4.4 Type 4 - Non-wholly-owned operational subsidiary with third-party participation: Company in which Vale or company of type 1 and 2 (a) directly or indirectly holds less than the total shareholding, (b) has share control and (c) whose business includes industrial, marketing and commercial activities, mineral exploration or technology development. 4.5 Type 5 - Operated Company, with Third Party Participation (OJVs – Operated Joint Ventures): Company in which Vale (a) holds, directly or indirectly, less than 100% of shares, (b) does not hold share control and (c) controls the company’s daily operational decisions, typically because of an operational agreement, shareholder agreement or other agreement between the company and Vale (for example, asset lease agreement). 4.6 Type 6 - Non-Operated Company, with Third Party Participation (NOJVs – Non-Operated Joint Ventures): The company in which Vale (a) holds, directly or indirectly, less than 100% of shares or even in the absence of shareholding (as in the case of a consortium), (b) does not hold shareholding control and (c) does not operate the company, because either the company has independent management under the direction of the Board of Directors and its shareholders, or the company is operated by one of the other shareholders or third party, under the terms of an agreement signed between the company and the operator; and (cd exercises significant influence on the governance of the company (for example, Vale or one of its subsidiaries (types 1 to 4) may appoint one or more persons to the Board of Directors or equivalent body). All of the three above-listed conditions must be met to classify a company as NOJV, therefore the ability to elect management members as a result of Vale's participation is not sufficient to classify it in this type. The entry into new NOJVs will be strategically evaluated, especially for new geographies, markets, and businesses, in addition to the obtaining of necessary approvals. It may also occur for different reasons, such as accessing complementarity of skills, products, and services, gaining scale or cost synergy, learning, or developing new skills, meeting regulatory requirements, sharing risks, accessing capital, asset monetization, or managing exit/acquisitions in phases. 4.7 Type 7 - Financial Investments/Minority Participations in Closed Companies: Private companies in which Vale (a) holds directly, indirectly, or via funds, small shareholdings, or quotas (less than 20%) and (b) does not exercise significant influence on the company’s governance. Examples of minority holdings include investments in (i) established companies that can aggregate new technologies or skills, (ii) innovations/technology start-ups, (iii) funds to promote research and innovations, or (iv) junior mineral exploration companies. Minority holdings generally aim to create strategic options for Vale’s business. These investments/participations must be relatively small, individually limited to $50 million (historic Vale’s investment cost). 4.8. Type 8 - Financial Investments/Minority Participations in Listed Companies: Companies listed on the stock exchange in which Vale (a) directly or indirectly holds a small shareholding (usually less than 20%) and (b) does not exercise significant influence on the governance of the company, even when it may elect one or more members of its governance bodies. 4.9.
