This presentation contains certain forward-looking statements with respect to the financial condition, capital adequacy, operations and business of the Group and certain plans and objectives of the management of the Group. Such forward-looking statements speak only as at the date of this presentation and undue reliance should not be placed upon such statements. Although the Group currently believes the forward-looking statements have a reasonable basis, they are not certain and involve known and unknown risks and assumptions, many of which are beyond the control of the Group, which may cause actual results, conditions or circumstances to differ materially from those expressed or implied in such statements. Readers are cautioned not to place undue reliance on forward-looking statements particularly in light of: current economic conditions, geopolitical events, and global banking uncertainty including recent examples of instability in the banking system and regulatory, government and central bank responses. Forward-looking statements can generally be identified by the use of forward-looking words such as "may", "will", "would", "could", "expect", "intend", "plan", "aim", "estimate", "target", "anticipate", "believe", "continue", "objectives", "outlook", "guidance" or other similar words, and include statements regarding the Group's intent, belief or current expectations with respect to the Group's business and operations, market conditions, results of operations and financial condition, capital adequacy and risk management. To the maximum extent permitted by law, responsibility for the accuracy or completeness of any forward-looking statements, whether as a result of new information, future events or results or otherwise, is disclaimed.

The material in this presentation does not constitute an offer to sell, or a solicitation of an offer to buy, any securities in the United States or in any other jurisdiction in which such an offer would be illegal. Any securities of the Group to be offered and sold have not been, and will not be, registered under the Securities Act of 1933, as amended (U.S. Securities Act), or the securities laws of any state or other jurisdiction of the United States. Accordingly, any securities of the Group may not be offered or sold, directly or indirectly, in the United States unless they have been registered under the U.S. Securities Act or are offered and sold pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the U.S. Securities Act and any other applicable U.S. state securities laws. Readers should also be aware that certain financial data in this presentation may be considered "non-Generally Accepted Accounting Principles (GAAP) financial measures" under Regulation G of the U.S. Securities and Exchange Act of 1934, as amended, and "non-International Financial Reporting Standards (IFRS) financial measures" under Regulatory Guide 230 'disclosing non-IFRS financial information' published by ASIC, including Net Profit After Tax ("statutory basis"), Net Profit After Tax ("cash basis"), earnings per share ("cash basis"), dividend payout ratio ("statutory basis"), dividend payout ratio ("cash basis"), dividend cover ("statutory basis") and dividend cover ("cash basis"). The disclosure of such "non-GAAP and non-IFRS❞ financial measures in the manner included in this presentation may not be permissible in a registration statement under the U.S. Securities Act. Although the Group believes that these "non-GAAP and non-IFRS" financial measures provide a useful means through which to examine the underlying performance of the business, such "non-GAAP and non-IFRS" financial measures do not have a standardised meaning prescribed by Australian Accounting Standards or IFRS and therefore may not be comparable to similarly titled measures presented by other entities. They should be considered as supplements to the financial statement measures that have been presented in accordance with the Australian Accounting Standards or IFRS and not as a replacement or alternative for them. Readers are cautioned not to place undue reliance on any such measures.

The Group uses four alternative macroeconomic scenarios to reflect a range of possible future outcomes in estimating the Expected Credit Loss (ECL) for significant portfolios, scenarios are updated based on changes in both the macroeconomic and geopolitical environment. 2. Revised APRA capital framework effective from 1 January 2023. 3. Assuming 100% weighting holding all assumptions including forward- looking adjustments constant and includes individually assessed provisions. 4. Central scenario is based on the Group's internal economic forecasts and market consensus as well as other assumptions used in business planning and forecasting. 5. The downside scenario contemplates the potential impact of possible, but less likely, adverse macroeconomic conditions, resulting from significant inflationary pressures exacerbated by supply chain disruptions, shortages of goods and labour, and heightened energy prices compounded by geopolitical risks. 33#34Provisioning through the cycle Forward-looking approach - customer, macroeconomic and sectoral considerations Forward- looking components Late expansion Economic cycle GDP Contraction Early expansion Higher Lower Lower CP - Base Higher CP - FLAS Higher Lower CP - MES IAPS² Likely lower¹ Higher Total provisions³ Higher Likely lower • AASB 9 requires a forward-looking approach to loan loss provisioning to dampen • • pro-cyclical provisioning behaviour through forward-looking adjustments (FLAs) and multiple economic scenarios (MES) in determining collective provisions (CP). Total provisions will likely be lower following an economic contraction (despite higher base provisions) as we adopt a forward-looking view of an economic expansion. Sectoral considerations (last 6 months): - - - - Consumer: little change to modelled provisions as actual customer losses remained well below long-run averages. Slight increase in FLAs for higher risk occupations (exposed to slower discretionary spending) and home loan customers under the greatest cost of living pressure. Construction: slight reduction in FLAs for sub-segments related to non-building, site preparation and trade services. Number of dwellings under construction is high, but new commencements are low, pointing to constrained future activity. Retail trade: non-material change in provisioning coverage. Anticipated slowdown in discretionary spending per capita due to cost of living pressures is materialising, though non-discretionary spending remains resilient. Entertainment, leisure and tourism: increased FLAs, driven by higher cost of living impacts on discretionary spending. Cafes and restaurants remain sub-sector of greatest concern. Commercial property: non-material change in provisioning coverage. Sales remain low, though prices starting to reflect impact of higher rates and vacancies. Agriculture: increased FLAs for potential impacts of climate-related events. Livestock prices improving from recent lows and a solid harvest expected across most crops from higher than average rainfall. 1. If economic conditions are expected to recover following a recession, then the MES overlay would reduce as economic variables improve and/or the probability weighting towards more benign scenarios increases. This may not be the case where further deterioration in economic conditions is expected (e.g. a double-dip recession). 2. Individually assessed provisions (IAPS) are raised for non-performing exposures. 3. This refers to expectations before and after an economic slowdown. How total provisions change during a contraction is uncertain: If FLAs and MES under-predict actual losses, then total provisions will increase. If they over-predict losses (as was the case during the early stages of the COVID-19 pandemic) then total provisions will decrease. 34#35Funding Conservative settings providing flexibility - repaid $19 billion of Term Funding Facility 1 Long-term funding² % of total funding Deposit funding % of total funding 55% 75% 75% 19% 18% Short-term funding4 % of total funding 18% 26% 819 825 197 190 WAM³ 3.5yrs 5.3yrs 5.2yrs 96 96 7% 7% LCR & NSFR Liquid assets NSFR HQLA5 $180bn 121% Non-HQLA excess liquids $20bn Liquidity Coverage Ratio7 Net Stable Funding Ratio (ex.

AASB 9 classifies loans into stages; Stage 1 - Performing, Stage 2 – Performing but significantly increased credit risk, Stage 3 – Non-performing. Performing relates to Stage 1 and Stage 2. Non-performing relates to Stage 3. Stage 2 is defined based on a significant deterioration in internal credit risk ratings, as well as other indicators such as arrears. Assessment of Stage 2 includes the impact of forward-looking adjustments for emerging risk. 2. Excludes estimated impairment provisions for derivatives at fair value. 3. Segmentation of loans in retail and risk rated portfolios is based on the mapping of a counterparty's internally assessed PD to S&P Global ratings (refer Pillar 3), reflecting a counterparty's ability to meet their credit obligations. 4. The assessment of significant increase in credit risk includes the impact of forward looking multiple economic scenarios in addition to adjustments for emerging risks at an industry, geographic location or particular portfolio segment level, which are calculated by stressing an exposure's internal credit rating grade at the reporting date. This accounts for approximately 62% of Stage 2 exposures as at 31 December 2023 (30 June 2023: 62%, 31 December 2022: 59%). In 1H24, the Group recalibrated the capital model for the large corporate portfolio which resulted in a higher proportion of exposures allocated to Stage 2 as at 31 December 2023. This change did not have an impact on provisioning coverage as the Group recognised an increase in provisions for the expected impact of the new model in the prior period. 80#81Retail Banking Services (RBS)¹ Consistent and disciplined execution Net Promoter Score² Dec 23 #1 MFI share² 34.7% 35.0% Dec 22 Dec 23 Volume growth³ 12 months to Dec 23 System CBA 35.0% 7.4% 6.1% 4.4 4.2% 16.5% 12.0% 11.9% 2.0% 1.7 0.2 CBA Peer 3 Peer 2 Peer 1 Home loans4 Household deposits5 (1.5) Peer 3 Peer 1 Peer 2 CBA Margin Lower margins due to increased competition and unfavourable deposit mix as customers switch to higher yielding savings and term deposits Cost-to-income Financials Increase driven by lower operating income due to lower margins and higher operating expenses % Group NPAT $m 1H24 vs 1H23 Income 6,465 (4%) 54% Expense Impairment NPAT (2,401) +3% (216) (10%) 2,687 (8%) 279 262 254 34.6% 35.5% 37.1% bpts 1H23 2H23 1H24 1H23 2H23 1H24 1, 2, 3, 4, 5.

The items excluded from cash profit, such as hedging and IFRS volatility and losses or gains on acquisition, disposal, closure, capital repatriation and demerger of businesses are calculated consistently with the prior year and prior half disclosures and do not discriminate between positive and negative adjustments. A list of items excluded from cash profit is provided on page 3 of the Group's 31 December 2023 PA, which can be accessed at our website: www.commbank.com.au/results CBA parent bank, offshore branches and extended licensed entities approved by APRA.

June and December 2023 measures based on the Australian Banking Association publication 'Basel 3.1 Capital Comparison Study' (March 2023), which compares APRA's revised capital framework, including RBNZ prudential requirements, with the finalised post-crisis Basel III reforms. December 2022 calculation is aligned with the APRA study entitled 'International capital comparison study' (13 July 2015). Tier 1 Capital divided by Total Exposures, expressed as a percentage. Total exposures are the sum of On Balance Sheet items, derivatives, securities financing transactions (SFTs), and Off Balance Sheet items, net of any Tier 1 regulatory deductions that are already included in these items. The LCR is the first quantitative liquidity measure that is part of the Basel III reforms. It was implemented by APRA in Australia on 1 January 2015. It requires Australian ADIs to hold sufficient liquid assets to meet 30 day net cash outflows projected under an APRA-prescribed stress scenario.
