The Retail Offer is part of Auckland Airport's equity raise announced on 16 September 2024, whereby Auckland Airport also undertook a fully underwritten $1.2 billion placement of new shares to existing institutional and other select investors in New Zealand, Australia, and other jurisdictions (“Placement”). Auckland Airport announced the successful completion of the Placement bookbuild on 17 September 2024, which was strongly supported and fully subscribed at a price of $6.95 per share. Eligible existing Auckland Airport shareholders with a registered address in New Zealand or Australia will receive their application forms to apply for up to a maximum of NZ$150,000 / AU$45,500(2) respectively of new Auckland Airport shares, free of any brokerage, commission and transaction costs in accordance with the terms and conditions in the Retail Offer Document. Auckland Airport will have the ability to scale applications or accept oversubscriptions at its discretion(1)(3). The price of these shares will be the lower of the Placement share price, being $6.95 per share, and a 2.5% discount to the five-day volume weighted average price of Auckland Airport shares traded on the NZX during the last five trading days of the Retail Offer period. A Retail Offer Document, together with an application form, will be sent today to eligible retail shareholders as at the record date of 13 September 2024 with a registered address in New Zealand or Australia and is available online at www.aucklandairportshares.co.nz. Applications can be made through this website or as otherwise directed by Auckland Airport. The closing date for applications by eligible shareholders is 4 October 2024. The new shares to be issued under the Retail Offer will rank equally in all respects with Auckland Airport’s existing ordinary shares. The new shares are not entitled to the final dividend to be paid on 4 October 2024 (with a record date of 19 September 2024). Key dates relating to the Retail Offer are set out in the Appendix to this announcement.

This announcement does not constitute an offer to sell, or the solicitation of an offer to buy, any securities in the United States or in any jurisdiction in which such an offer would be illegal. The offer and sale of shares under the Retail Offer have not been, and will not be, registered under the U.S. Securities Act of 1933 (the “U.S. Securities Act”) or the securities laws of any state or other jurisdiction of the United States. Accordingly, such shares may not be offered or sold in the United States except in transactions exempt from, or not subject to, the registration requirements of the U.S. Securities Act and any other applicable securities laws of any state or other jurisdiction of the United States. Note: Currency in NZD unless specified otherwise (1) With the ability to accept oversubscriptions at Auckland Airport’s sole discretion, if required to allow participating shareholders to maintain their proportionate ownership, noting the individual application caps for eligible shareholders in the Retail Offer and regulatory restrictions. (2) If an eligible shareholder in Australia applies for an Australian dollar amount of shares, and the exchange rate varies such that the Australian dollar amount applied for exceeds the NZ$50,000 regulatory limit (converted in accordance with the Retail Offer Document), shares having a total issue price equal to NZ$50,000, which may be less than A$45,500, will be issued to the shareholder, and they will be refunded the excess cash amount on the terms set out in the Retail Offer Document. The lower limit on participation for Australian eligible shareholders reflects the legal rules applicable to offers of this nature in Australia, as increased by ASIC Instrument 24-0755. (3) If Auckland Airport decides to scale applications, it will do so by reference only to the number of fully paid ordinary shares held by eligible shareholders accepting the Retail Offer at 7:00 pm New Zealand time on 13 September 2024. This approach is intended to ensure, as far as is practicable, shareholders who apply for a number of shares that will allow them to maintain their proportionate ownership in Auckland Airport will receive those shares. However, Auckland Airport’s ability to scale in this manner is subject to the overall size of the Retail Offer and regulatory restrictions on the number of shares that can be offered to eligible shareholders. Refer to the Retail Offer Document, for further details regarding Auckland Airport's intended approach to scaling. (4) The timetable presented is indicative only and is subject to change without notice (subject to applicable laws and NZX Listing Rules and ASX Listing Rules). All dates and times are New Zealand times (unless stated otherwise).
