In voting FOR the recommendation, Glass Lewis noted, among other things, that:

• . . . that the Company and the board of directors conducted a reasonably comprehensive review process in the months preceding the execution of the Organization Agreement.
• . . . we recognize that an individual company case may also reasonably be considered to carry a relatively elevated risk profile.
• . . . shareholders should consider that the company faces significant financing risks in the near term.
• . . . we are inclined to believe that Rio Tinto’s current offer represents a reasonable exit price and a compelling market premium for minority shareholders, overall.

Turquoise Hill chairman Peter Gillin said: “Glass Lewis’ recommendations confirm the work of the five independent directors on the Special Committee who have dedicated six months to an extensive process of analysis and negotiation to secure a transaction that is in the best interests of the Company and is fair to the Company’s minority shareholders. The deal gives Turquoise Hill’s minority shareholders the opportunity to realize the value of their investment through a fee of C$43.00 per share, providing a 67% premium to Turquoise Hill’s share price at the close on March 11. 2022, the last trading day before Rio Tinto’s initial offer to acquire a minority stake in the company. Moreover, the transaction, if approved, will relieve the minority shareholders of the financial, technical, market and geopolitical risks and uncertainties that the Company faces in developing and operating a massive complex block cave mine in a remote part of Mongolia. directors and the Special Committee reiterate their unanimous recommendation that the Company’s minority stockholders vote FOR the resolution approving the Agreement.”
