Chief Executive Carrie Hurihanganui said she was very pleased with the level of support for the Placement, and the broader capital investment programme shown by the investment community, to enable Auckland Airport to deliver critical infrastructure that will add resilience and provide greater airline capacity growth. Settlement of the Placement is expected to occur on 19 September 2024 for the ASX and on 20 September 2024 for the NZX, with allotment and commencement of trading on NZX and ASX expected to occur on 20 September 2024. The new shares to be issued under the Placement will rank equally in all respects with Auckland Airport’s existing ordinary shares quoted on the NZX and ASX from the date of allotment. New shares are not entitled to the final dividend to be paid on 4 October 2024 (with a record date of 19 September 2024).
