COMPANY DISCLOSURES

STOCK EXCHANGE LISTINGS

Mercury NZ Limited (referred to in this section as “Mercury” or “the Company”) is listed on the New Zealand stock exchange and as an ASX Foreign Exempt Listing on the Australian stock exchange.

In New Zealand, Mercury is listed with a “non-standard” (NS) designation. This is due to particular provisions of the Constitution, including the requirements regulating ownership and transfer of Ordinary Shares.

ASX approved a change in Mercury NZ Limited’s ASX admission category from an ASX Listing to an ASX Foreign Exempt Listing, effective from the commencement of trading on 19 February 2016.

The Company continues to have a full listing on the NZX Main Board, and the Company’s shares are still listed on the ASX. The Company is primarily regulated by the NZX, complies with the NZX Listing Rules, and is exempt from complying with most of the ASX Listing Rules (based on the principle of substituted compliance).
