ÌÇÐÄvlogÈë¿Úoperates under a dual listed companies (DLC) structure. Since its formation in 1995, this cost effective structure has been designed to, in a tax efficient way, place the shareholders of ÌÇÐÄvlogÈë¿Úplc and ÌÇÐÄvlogÈë¿ÚLimited in substantially the same position as if they held shares in a single entity owning all of the assets of both companies. Under the DLC structure, the businesses of ÌÇÐÄvlogÈë¿Úplc and ÌÇÐÄvlogÈë¿ÚLimited are managed together, the boards of directors of each Company are the same, and shareholders of each Company have a common economic interest in the DLC structure.
We continue to regularly review all elements of the business, including the company structure, to ensure it is maximising shareholder value. As recently as 2024, an extensive independent review was conducted. The Board unanimously concluded that the DLC structure continues to be effective and provides benefits to ÌÇÐÄvlogÈë¿Úand our shareholders.
Franking credits are Australian tax credits available to shareholders because we pay Australian corporate tax on profits our Australian assets generate before we pay dividends to shareholders.
ÌÇÐÄvlogÈë¿ÚLimited shareholders who are to offset tax liabilities on their dividends. Those who aren’t Australian tax residents can’t use them, other than for Australian withholding tax, which most non-residents don’t pay.
So franking credits are effectively wasted for shareholders who aren’t Australian tax residents.
The DLC structure allows us to only pay franked dividends to Australian tax-resident shareholders. If we unified the structure, we’d need to attach franking credits to all dividends, meaning those paid to the 77 per cent of ÌÇÐÄvlogÈë¿ÚLimited shareholders who aren’t Australian tax-residents would be “wasted”.
Under a unified structure, we anticipate we wouldn’t be able to pay fully franked dividends – so Australian tax-resident shareholders wouldn’t benefit from franking credits.

The ADRs evidence ÌÇÐÄvlogÈë¿Úplc American Depositary Shares (ADS), each representing one ordinary share.

There are disclosure requirements in the UK and Australia applying to holders of substantial shareholdings in ÌÇÐÄvlogÈë¿Úplc and ÌÇÐÄvlogÈë¿ÚLimited respectively. These requirements are summarised below. The particular application of these requirements will depend on matters specific to the shareholding and the shareholder’s circumstances. If a holder is unclear on the application of these requirements, it is recommended they seek legal advice.
The Australian Securities and Investments Commission (“ASIC”) has made various declarations1 modifying the application of the Australian Corporations Act as it applies to Rio Tinto’s dual listed companies structure . These modifications include changes to the substantial shareholder disclosure requirements under Chapter 6C of the Corporations Act.
The modified provisions require any person and their associates2 with voting power of 5 per cent or more in ÌÇÐÄvlogÈë¿ÚLimited to give notice to ÌÇÐÄvlogÈë¿ÚLimited and ASX when that holding is created, ceases or is increased or decreased by at least one per cent.
Further, the modified disclosure provisions also require a person and their associates2 to aggregate their holdings of both ÌÇÐÄvlogÈë¿Úplc and ÌÇÐÄvlogÈë¿ÚLimited shares to determine if there is a requirement to disclose an interest in ÌÇÐÄvlogÈë¿ÚLimited. In broad terms, these provisions require that a person’s interest in voting shares in ÌÇÐÄvlogÈë¿Úplc is taken to give rise to an interest in ÌÇÐÄvlogÈë¿ÚLimited calculated as a percentage of the combined voting share capitals of ÌÇÐÄvlogÈë¿Úplc and ÌÇÐÄvlogÈë¿ÚLimited.
So for example, where a shareholder and its associates2 hold:
for the purposes of the modified disclosure provisions, the holdings should be aggregated, resulting as shown below in a disclosable interest in ÌÇÐÄvlogÈë¿ÚLimited of 6.17%:
Holdings of Shareholder and its associates2
Issued voting capital
% of voting capital held in individual listed entities
Voting capital in each entity as a % of combined voting share capital
ÌÇÐÄvlogÈë¿Úplc
80,000,000
1,249,923,674
6.40%
4.93%
ÌÇÐÄvlogÈë¿ÚLimited
20,000,000
371,216,214
5.39%
1.23%
Aggregated
1,621,139,888
6.17%
These modified rules apply even if a person does not hold any shares in ÌÇÐÄvlogÈë¿ÚLimited.
There is no corresponding requirement in the UK to aggregate ÌÇÐÄvlogÈë¿Úplc and ÌÇÐÄvlogÈë¿ÚLimited shareholdings for the purpose of disclosure under the DTRs.
1 These declarations are set out in ASIC instruments numbered 01/1038, 01/1039, 01/1040 and 01/1041, which were gazetted by ASIC on 28 August 2001.
2As defined in Division 2 of Part 1.2 of the Corporations Act, as modified by ASIC instrument 01/1038.
