TRQ Turquoise Hill Resources Ltd

Pentwater Capital Management LP ("Pentwater"), a long-term supportive investor and the largest minority shareholder of Turquoise Hill Resources Ltd. ("Turquoise Hill" or the "Company") (TSX:TRQ) (NYSE:TRQ), owning, together with its affiliates and associates, approximately 9.09% of the Company's issued and outstanding common shares, today filed a proxy circular, GOLD proxy card, and issued a letter to shareholders of Turquoise Hill in connection with the Company's upcoming annual and special meeting of shareholders scheduled for 9:00 a.m. (Eastern Time) on May 12, 2020 (the "Meeting") in the Saint-Laurent 5 room of Hôtel Bonaventure Montreal, located at 900 Rue de la Gauchetière Ouest, Montreal, Quebec, Canada.

Since Rio Tinto plc. (NYSE:RIO:US)(LON:RIO:L)(ASX:RIO:AX) ("Rio Tinto") gained control of Turquoise Hill in 2012, Pentwater has grown increasingly alarmed at the significant value destruction and mismanagement of and failure to make material disclosures about the Company and its material asset – the Oyu Tolgoi Project – at the hands of Rio Tinto and its hand-picked Turquoise Hill officers and directors. The tangled web that has been woven between Rio Tinto and Turquoise Hill has resulted in a lack of corporate governance controls, systemic disregard for the interests of minority shareholders, a sustained period of false and misleading disclosures and irreparable harm to the interests of all Turquoise Hill stakeholders.

The Oyu Tolgoi Project is one of the largest known copper and gold deposits in the world, containing ore that is six times the average-industry grade. If managed and operated properly, the Oyu Tolgoi Project should reap exceptional benefits for all stakeholders – including the people and government of Mongolia and the majority and minority shareholders of Turquoise Hill.

It is time to take action against the current culture of entrenchment, value destruction and misconduct at Turquoise Hill. At the Meeting, Pentwater is seeking the support of Turquoise Hill shareholders to vote using the GOLD form of proxy or VIF FOR:

• the election of the highly qualified and meaningfully independent director nominee, Matthew Halbower, Chief Executive Officer and Chief Investment Officer of Pentwater, to the board of directors of the Company; and
• the adoption of a shareholder proposal, which would provide minority shareholders of Turquoise Hill with the exclusive right to nominate and elect three of seven directors to the board of directors of the Company.

Turquoise Hill shareholders have the opportunity to initiate much-needed change, to restore accountability and to safeguard minority shareholder interests in Turquoise Hill. By electing Matthew Halbower to the board of directors of the Company, minority shareholders will for the first time have a director representing them whose interests are fully aligned with theirs, rather than Rio Tinto's, which is exemplified by Pentwater's significant investment in Turquoise Hill.

To ensure your vote is counted, please vote using the GOLD form of proxy or GOLD VIF prior to 5:00 p.m. (Eastern Time) on Thursday, May 7, 2020. You should discard any management proxies or VIFs that you receive.

Shareholders are urged to read the full text of Pentwater's proxy circular and letter to shareholders, which are available under Turquoise Hill's issuer profile on SEDAR at www.sedar.com.
