"ANZ 2030 Strategy

The ANZ Group announced ANZ 2030 on 13 October 2025, an update on the ANZ Group's immediate priorities and its strategic focus for the next five years.

ANZ 2030 is focused on four strategic pillars

• Customer First With market leading, differentiated and superior propositions, raise the standard of every digital and human interaction for its customers;
• Simplicity To set the market standard for productivity, deliver organisational simplification, divest non-core assets and improve efficiency;
• Resilience Leading the industry in trust, safety and risk management, adhere to the highest standards of nonfinancial risk management and strengthen end-to-end accountability across the ANZ Group; and
• Delivering Value To sustainably improve the ANZ Group's financial performance, create lasting value by delivering higher returning growth and results that matter for its stakeholders.

Five key immediate priorities

The ANZ Group has five key immediate priorities:

• 1. Embedding the ANZ Group's new leadership team;
• 1. Integrating Suncorp Bank faster to deliver value; 1
• 3. Accelerating the delivery of the ANZ Plus digital front-end to all of the ANZ Group's retail and small business customers; 2
• 1. Reducing duplication to simplify the ANZ Group, while stopping initiatives that do not align with the ANZ Group's strategy; and
• 1. Enhancing non-financial risk management to improve customer outcomes.

Capital

The ANZ Group will be implementing certain capital management actions, including the following:

• Share buy back – Cease the remaining approximately A\$800 million of ANZGHL's share buy-back. This allows ANZGHL to return surplus capital of approximately A\$1 billion from ANZGHL to ANZBGL³ ; and
• Dividend reinvestment plan – Apply a 1.5% discount on the next two dividend reinvestment plans, which it expects will not be neutralised.⁴

Certain additional information

Two phases to ANZ 2030

The first phase is across financial year ending 30 September 2026 ("Financial Year 2026") and financial year ending 30 September 2027 ("Financial Year 2027") and is delivering on immediate priorities to get the basics right:

• Substantial improvement in productivity
• Initial investment for growth

1 ANZBGL's aim is to complete a safe and secure migration of Suncorp Bank customers to ANZBGL by June 2027.

² ANZ Plus will now be delivered in a different sequence and through a new, more efficient delivery model. ANZBGL is prioritising the development of the front-end of ANZ Plus and is aiming to upgrade all 8 million retail customers in Australia to this new, superior, single channel experience by September 2027.

³ Approximately A\$1 billion of surplus capital, including the remaining share buy-back of A\$825 million and other capital of approximately A\$200 million, will be transferred from ANZGHL to ANZBGL.

⁴ Any application of a discount and any determination not to neutralise the dividend reinvestment plan are subject to ANZGHL's capital position at the relevant time and a determination by its Board to pay a dividend for that period.

The second phase is beyond Financial Year 2027 and is realising the benefits of these strong foundations:

• Accelerating growth
• Outperforming the market

The ANZ Group to achieve a cost-to-income ratio in the mid-40s (as a percentage) by the financial year ending 30 September 2028 and to sustain this through to the financial year ending 30 September 2030.

Integration of Suncorp Bank faster

Since the announcement in July 2022 of ANZBGL's agreement to acquire Suncorp Bank, there has been a 19% growth in Suncorp Bank customer deposits and an 18% growth in net loans and advances by Suncorp Bank.

Path forward to migrate Suncorp Bank to ANZBGL:

• safe and secure migration of Suncorp Bank customers to ANZBGL by June 2027;
• the ANZ brand offers Suncorp Bank customers a wider range of products and an expanded network; and
• ANZBGL will meet its commitments to the Australian Government and the Queensland State Government regarding ANZBGL's acquisition of Suncorp Bank.

There are:

• estimated total cost synergies (pre-tax) of A\$500 million per annum full run-rate from the financial year ending 30 September 2029. This represents approximately 50% to 55% of Suncorp Bank's cost base.⁵
• estimated integration costs (pre-tax) of A\$745 million.

Accelerated delivery of ANZ Plus

Currently there are three technology stacks across the ANZ, ANZ Plus and Suncorp Bank businesses:

• 3 digital front-ends;
• 3 middleware platforms; and
• 2 core banking systems.

By September 2027, ANZ Group's target is to have 8 million retail customers in Australia upgraded to the ANZ Plus frontend, providing them with a new, superior, single channel experience:

• 1 digital front-end;
• 2 middleware platforms; and
• 1 core banking system.

Post 2027, the re-platforming of the middleware and the elimination of existing middleware legacy platforms will occur:

• 1 digital front-end;
• 1 middleware platform; and
• 1 core banking system.

⁵ For example, this represents 55% of Suncorp Bank's expenses for the financial year ending 30 September 2024 (based on 2 months of annualised expenses when Suncorp Bank was owned by the ANZBGL Group, but excluding an accelerated software amortisation charge of A\$36 million).

Unless otherwise indicated, all financial performance metrics above are on a cash profit basis. Sum of parts within commentary may not equal totals due to rounding."

"Appointments to ANZ Group Executive Committee

The Board of ANZ Group announced on 9 October 2025 three new senior leadership appointments to the Group Executive Committee, reporting to Chief Executive Officer Nuno Matos.

• Pedro Rodeia who will join as Group Executive Australia Retail on 17 November 2025;
• Christine Palmer who will join as Group Chief Risk Officer on 1 December 2025; and
• Donald Patra who will join as Group Chief Information Officer on 24 November 2025.
