Dividend Reinvestment Plan strike price

Mercury advises that the price at which shares will be transferred for the FY2024 final ordinary dividend under the Company’s Dividend Reinvestment Plan (DRP) is NZ$5.8645 per share. The price has been determined, in accordance with the terms and conditions of the DRP Offer Document, as the average of the daily volume weighted average sale price for a share, calculated on all price setting trades of shares that took place through the NZX Main Board over a period of five trading days starting on 16 September 2024, less a 2.0% discount. Shareholders who have elected to participate in the DRP will receive shares instead of cash in respect of the FY2024 final ordinary dividend payable on 30 September 2024.
