This consolidated entity disclosure statement (CEDS) has been prepared as at 31 December 2025.

For all entities within this CEDS, place (country) of incorporation, classes of shares, the registered office address, the percentage of the

share class held by Group entities, and the effective percentage of equity owned by the Group calculated by reference to voting rights, are

disclosed. The share class held by the Group are ordinary (voting) shares (also referred to as common stock in certain countries), unless

identified with one of the following annotations against the entity name:

(1) ordinary/common; (2) preference; (3) redeemable preference; (4) unit; (5) redeemable preference B; (6) registered; (7) special voting; (8) DLC

dividend; (9) founder’s; (10) non-cumulative redeemable preference; (11) non-redeemable preference; (12) deferred; (13) Class A; (14) Class B; (15)

Class/Series C; (16) Class/Series D; (17) Class/Series E; (18) Series F; (19) Series G; (20) Class H; (21) Class J; (22) Class S; (23) Class Z; (24) E1

Class.

Additionally, for subsidiaries and other consolidated entities, the entity’s tax residency; whether the entity was a body corporate, partnership

or trust; and whether the entity was a partner in a partnership, a trustee of a trust or a participant in a joint venture within the consolidated

Group, are also disclosed. Unless otherwise disclosed, each entity in this CEDS is a body corporate.

Unless otherwise disclosed, the tax residency of subsidiaries and other consolidated entities is the same as the country of incorporation. The

determination of tax residency involves judgement as the determination of tax residency is highly fact dependent and requires interpretation

of relevant legislation, guidance and judicial precedent. Different interpretations could be adopted which could give rise to a different

conclusion on residency. In determining tax residency, the Group has applied current legislation, judicial precedent and other available

guidance.

Refer to the “Basis of consolidation” on page 158 for further information on accounting policies, basis of consolidation, subsidiaries with

material non-controlling interests, joint operations, joint ventures and associates.

An explanation of the dual-listed companies structure of Rio Tinto plc and Rio Tinto Limited can be found on pages 336 to 337.

For completeness, the effective ownership by the Group relates to effective holdings by both entities either together or individually.

Entities are listed by place (country) of incorporation and under their registered office address.
