2021 Annual Shareholder Meeting

Turquoise Hill 2021 Annual Shareholder Meeting

This control number can be used to vote at the Meeting. Such 13-digit proxyholder number will differ from the control number set forth on the form of proxy or voting information form.

Without the 13-digit proxyholder control number, the proxyholder will be able to attend the Meeting as a guest, but will not be able to ask questions or vote at the Meeting.
