Rio Tinto cash tender offer targeting $1.2 billion of its 3.750 per cent Notes due 2025

Rio Tinto Finance (USA) Limited (the "Offeror") is today making an offer to purchase (the "Offer") for cash any and all of the outstanding Securities listed in the table below, which are guaranteed by Rio Tinto plc and Rio Tinto Limited (the "Securities") in order to manage its debt maturity profile.

The terms and conditions of the Offer are described in the offer to purchase (the "Offer to Purchase"), dated as of today. Capitalised terms not otherwise defined in this announcement have the meaning given to them in the Offer to Purchase.

Rio Tinto Finance (USA) Limited is offering to purchase for cash, upon the terms and subject to the conditions set forth in the Offer to Purchase and the Notice of Guaranteed Delivery, any and all of the outstanding Securities:

*The Fixed Spread is equivalent to the spread in the "Optional Redemption" provision under the Securities. The Purchase Price will be calculated with reference to the Maturity Date (being 15 June 2025), in line with the expected approach to the calculation of the Make Whole Redemption Price in accordance with the terms and conditions of the Securities.

Purpose of the Offer

The Offeror is making the Offer to refinance a portion of its existing debt. The Offer, together with a proposed offering of a new series of debt securities, is intended to extend the Offeror's debt maturity profile. Securities purchased in the Offer will be retired and cancelled.

Following the completion of the Offer and provided that the Financing Condition is met, the Offeror intends to redeem any remaining outstanding Securities in accordance with their terms and conditions at the Make Whole Redemption Price. Nothing in this announcement or the Offer to Purchase constitutes a redemption notice. The Offeror notes that the spread used to calculate the Make Whole Redemption Price will be the same as the Fixed Spread pursuant to the Offer.

The Offer

The Offer will expire at 5pm, New York City time, on 3 November 2021, unless extended. The Purchase Price for the Securities validly tendered and accepted for purchase pursuant to the Offer will be determined based on a yield to the Maturity Date of the Securities as of the Settlement Date equal to the sum of the Fixed Spread over the bid-side yield to maturity on the U.S. Reference Treasury Security, each as set forth in the table above, determined in accordance with standard market practice and as described in the Offer to Purchase as of 10am, New York City time, on 3 November 2021. Holders will also receive Accrued Interest on the applicable settlement date for the Offer. The Settlement Date for the Offer is expected to be 5 November 2021 (or 8 November 2021 in the case of Securities delivered pursuant to the guaranteed delivery procedures described in the Offer to Purchase). Accrued Interest will cease to accrue on the Settlement Date, and (in the case of Securities for which the Guaranteed Delivery Procedures are used) no additional accrued interest will be paid in respect of the period from the Settlement Date to the Guaranteed Delivery Settlement Date.

The Offer is subject to the satisfaction of certain conditions set forth in the Offer to Purchase, including a Financing Condition that the Offeror shall have completed prior to the expiration deadline an offering of USD-denominated debt securities ("New Notes") on terms and subject to conditions satisfactory to it in its sole discretion which is described in the Offer to Purchase. If any of the conditions are not satisfied or waived by the Offeror, the Offeror will not be obligated to accept for purchase, purchase or pay for, validly tendered Securities, in each case subject to applicable laws, and may terminate the offer. The Offer is not conditioned on the tender of a minimum principal amount of Securities.The Offeror cannot assure you that any financing will be successful and the Offeror reserves the right to waive any and all conditions of the Offer on or prior to the Expiration Deadline.

When considering any potential allocation of New Notes, the Offeror intends, but is not obligated, to give some degree of preference to those investors who, prior to such allocation, have validly tendered, or have indicated to the Offeror or the Dealer Managers their firm intention to tender, Securities in the Offer. See "Terms and Conditions of the Offer-Allocation of New Notes" in the Offer to Purchase for further details.

Following consummation of the Offer, the Securities that are purchased in the offer will be retired and cancelled and no longer remain outstanding.
