Rio Tinto plc and Rio Tinto Limited have announced they are no longer considering a possible merger or other business combination with Glencore plc. The group concluded it could not reach an agreement that would deliver value to its shareholders, applying the disciplined framework outlined at its Capital Markets Day in December 2025.
The company issued this as a formal “no intention to bid” statement under Rule 2.8 of the UK Takeover Code. As a result, Rio Tinto and any concert parties are now restricted by Rule 2.8, although they retain limited rights to reconsider a transaction if specific events occur, such as a third-party offer for Glencore or a material change of circumstances.
