Turquoise Hill Enters into Definitive Agreements with Rio Tinto

Turquoise Hill Resources Ltd. ("Turquoise Hill" or the "Company") (TSX: TRQ) (NYSE: TRQ) announced today that, based on the unanimous recommendation of an independent special committee of its board of directors (the "Special Committee"), it has entered into an arrangement agreement (the "Arrangement Agreement") with Rio Tinto plc and Rio Tinto International Holdings Limited ("Rio Tinto"), a wholly-owned subsidiary of Rio Tinto plc, in respect of a transaction whereby Rio Tinto will acquire the approximately 49% of the issued and outstanding common shares of the Company that Rio Tinto does not currently own (the "Minority Shares") for C$43.00 in cash per share (the "Transaction"), subject to approval by the Turquoise Hill minority shareholders and other customary closing conditions. Today's announcement is the culmination of negotiations that took place following the September 1, 2022 public announcement of the term sheet entered into in connection with the Transaction.

The purchase price of C$43.00 per share reflects a 67% premium to Turquoise Hill's closing price of C$25.68 per share on the Toronto Stock Exchange on March 11, 2022, being the last trading day prior to Rio Tinto's initial public proposal to acquire Turquoise Hill (the "Initial Proposal"), and a 19% premium to Turquoise Hill's closing price of C$36.12 on August 31, 2022, being the last trading day prior to the September 1, 2022 announcement of the term sheet.

   Special Committee and Board Approval   

The Special Committee was established by the Turquoise Hill Board of Directors (the "Board") to consider the Initial Proposal, as well as other alternatives available to the Company and, if it deemed advisable, negotiate with Rio Tinto. Following a comprehensive evaluation of the Initial Proposal and extensive negotiations between the Special Committee and Rio Tinto on price and other terms of the Transaction, including amendments to the financing heads of agreement between the Company and Rio Tinto dated May 18, 2022 (the "HoA") to address the Company's near-term liquidity while the Transaction is pending, the Special Committee unanimously recommended that the Board approve the Transaction. The Board (excluding conflicted directors), having received the unanimous recommendation of the Special Committee, unanimously determined that the Transaction is in the best interests of Turquoise Hill and fair to the shareholders of Turquoise Hill other than Rio Tinto and its affiliates (the "Minority Shareholders") and recommends that Minority Shareholders vote in favour of the Transaction at the special meeting of shareholders to be held to approve the Transaction.

   Formal Valuation and Fairness Opinions   

In connection with its review of the Transaction, the Special Committee retained TD Securities Inc. ("TD") to prepare a formal valuation in accordance with Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions . TD delivered an oral opinion to the Special Committee that, as of August 31, 2022, and based on TD's analysis and subject to the assumptions, limitations and qualifications to be set forth in TD's written valuation, the fair market value of the common shares of the Company is in the range of C$42.00 to C$58.00 per common share. TD also delivered an oral opinion to the Special Committee that, as of August 31, 2022, and subject to the assumptions, limitations and qualifications to be set forth in TD's written fairness opinion, the consideration to be received by the Minority Shareholders is fair, from a financial point of view, to such Minority Shareholders.

The Special Committee retained BMO Capital Markets ("BMO") as its financial advisor in connection with its review of the Transaction. BMO delivered an oral opinion to the Special Committee that, as of September 5, 2022 and subject to the assumptions, limitations and qualifications to be set forth in BMO's written fairness opinion, the consideration to be received by the Minority Shareholders pursuant to the Transaction is fair, from a financial point of view, to such Minority Shareholders.

The Transaction is to be effected by way of a court-approved plan of arrangement under the Business Corporations Act (Yukon).   The consummation of the Transaction is subject to a number of conditions customary to transactions of this nature, including, among others: (i) the approval of 66.67% of votes cast by the Company's shareholders (including Rio Tinto) at a special meeting of shareholders; (ii) the approval of a simple majority of the votes cast by Minority Shareholders at such meeting; and (iii) court approval.

Concurrently with entering into the Arrangement Agreement and as contemplated by the term sheet entered into on September 1, 2022, Rio Tinto and the Company entered into a further amended HoA in order to address the Company's near-term liquidity needs while the Transaction is pending. The primary amendments to the HoA include:

• Increasing the early advance facility agreed in May 2022 to US$650 million from US$400 million, provided that if there is an anticipated funding shortfall for March 2023, the parties will in good faith discuss increasing the early advance facility by up to an additional US$100 million;
