ASX Release Level 18, 275 Kent Street Sydney, NSW, 2000 22 October 2024 WESTPAC’S FULL YEAR 2024 (FY24) NOTABLE ITEMS AND REPORTING CHANGES FY24 Notable Items Westpac’s reported net profit after tax in FY24 will be reduced by $123 million due to Notable Items that relate solely to unrealised fair value gains and losses on economic hedges and net ineffectiveness on qualifying hedges, which reverse over time. A summary of the impacts is included in Appendix 1. FY24 Reporting Changes Segment operating income and operating expenses were restated in First Half 2024 (1H24) following the establishment of separate Consumer and Business & Wealth operating segments, the dissolution of the Specialist Businesses operating segment and other reporting enhancements. For further information see 1H24 Notable Items and Reporting Changes ASX release. In Second Half 2024 (2H24) additional restatements have been made for: • Reclassification of some deposit products from interest bearing to non interest bearing. This included some mortgage offset accounts which had a minor impact on average interest earning assets; and • Reallocation of Enterprise functions' operating expenses to the Consumer, Business & Wealth and Westpac Institutional Bank segments. These changes do not impact the Group's net profit after tax (NPAT) or the composition of line items. A summary of the restatements is included in Appendix 2. Full Year 2024 results are scheduled to be announced on Monday, 4 November 2024.
