Revenue from investment banking grew by 33.7%, driven by the issue and distribution of fixed income securities. Additionally, revenue from payments and collections increased, due to higher volume of acquiring-related transactions. Result from insurance operations increased by 5.7% in the quarter, as a consequence of the higher remuneration of our assets. • Non-interest expenses increased by 4.0% in the quarter, driven by the effects of the negotiation of the collective wage labor agreement, which included a 5.68% adjustment to salary and benefits beginning in September 2025. Given this dynamic in the results, our efficiency ratio was 39.5% on a consolidated basis and 37.7% in Brazil in the third quarter. Management commentary Executive Summary Management Discussion & Analysis > Executive Summary The recurring managerial result reached R$11.9 billion in the third quarter of 2025, a 3.2% increase from the previous quarter. The recurring managerial return on equity was 23.3% on a consolidated basis and 24.2% in operations in Brazil. • The loan portfolio increased by 0.9% in the consolidated figures and by 1.2% in Brazil in the quarter, while annual growth was 6.4% and 7.8%, respectively. Excluding the effect of the foreign exchange variation on Middle-Market, Corporate and Latin America portfolios, the consolidated loan portfolio increased by 1.7% in the quarter. • The individual loans portfolio was up by 1.0%, with a 2.0% growth in mortgage loans and a 0.8% increase in credit cards. Even though payroll loans decreased by 0.5% in the quarter, private payroll loans increased by 9.5%. • The loan portfolio for very small, small and middle-market companies grew 1.1% in the quarter, and the highlight was the increase of 10.9% in the portfolio of government programs. • The financial margin with clients grew by 0.5% compared to the previous quarter. The positive effects of the greater number of days and the higher average volume of assets, in addition to the higher margin with working capital, were mainly offset by lower margins due to spreads and structured wholesale operations. • Nonperforming loans 15 to 90 days overdue ratio (NPL 15-90), including securities, increased by 0.3 p.p., closing the quarter at 2.0%. The ratio increased by 0.9 p.p. in the corporate segment in Brazil, closing the quarter at 1.0%. The increases on a consolidated basis and in the corporate segment were due to a specific client, who was already adequately provisioned and classified in stage 3. If we excluded this specific case, the ratios would have remained at the same levels as the previous quarter, that is, 1.7% on a consolidated basis and 0.1% in the corporate segment in Brazil. • Consolidated nonperforming loans 90 days overdue ratio (NPL 90), including securities, remained stable, as well as the ratio for operations in Brazil, remaining at 1.9% and 2.0%, respectively. • Cost of credit increased by 0.6% compared to the previous quarter and reached R$9.1 billion. Cost of credit over the ave- The recurring managerial result posted an increase of 13.1%, and reached R$34.5 billion in the first nine months of 2025. The recurring managerial return was 22.9% on a consolidated basis and 23.9% in Brazil, an increase of 0.7 p.p. in both cases. • The financial margin with clients increased by 13.4% on a year-on-year basis, due to the increases in loan portfolio, liabilities’ margin and the higher remuneration of our own working capital. • The financial margin with the market was down by 23.7%, mainly due to the increase in the cost of hedging the capital ratio. • Cost of credit was up by 5.3% due to loan portfolio growth. • Commissions and fees and result from insurance operations rose by 5.3%. Revenues from card issuing activities, asset management and payments and collections, as well as result from insurance operations as consequence of higher premiums earned, increased. • Non-interest expenses were up by 8.9%, whereas the efficiency ratio reached 38.8% on a consolidated basis and 36.9% in Brazil, decreases of 0.3 p.p. and 0.7 p.p., respectively.

Below are the main changes, compared with the previous quarter: • Working capital and other (+ R$0.1 billion): mainly driven by the positive effect of net income in the period on the balance of working capital. • Average volume (+ R$0.1 billion): positive impact due to an increase in the average profitable portfolio, with highlights being the increases in mortgage loans and government programs for small companies. • Product mix (- R$0.1 billion): decreased as a result of the lower share of more profitable products, such as revolving credit, partially offset by the higher relative growth of the portfolio of government programs for small companies. • Spreads and liabilities’ margin (- R$0.2 billion): mainly due to the negative impact of the lower asset spreads, driven by the compression of spreads in products with regulated rates, such as revolving credit and payroll loans, partially offset by the positive effect of the higher average remuneration rate and a higher average volume of liabilities. Compared to the first nine months of the previous year, the financial margin with clients was up by 13.4%, driven by the greater volume of credit and higher liabilities’ margin (both in terms of volume and remuneration rate), as well as a higher margin from our own working capital. The financial margin with the market increased by 5.2% in the quarter, mainly driven by higher gains from management of assets and liabilities in Brazil. Compared to the first nine months of the previous year, the 23.7% reduction was driven by the higher cost of hedging the capital ratio.

Cost of credit increased in the Retail business segment in Brazil, in line with the growth of the credit portfolio, partially offset by the lower cost of credit both in the Wholesale business segment in Brazil and in Latin America. In Latin America, the reduction was due to the improvement in ratings of specific corporate clients. Cost of credit was up R$1.4 billion compared to the first nine months of 2024, driven by the increase in the portfolio, whereas cost of credit over the portfolio was down by 0.1 p.p. on a year-on-year basis. The increases in the Retail business segment in Brazil of R$1.5 billion and in the Wholesale business segment in Brazil of R$0.6 billion were partially offset by the decrease of R$0.7 billion in the cost of credit in Latin America. Recovery of Loans Written off as Losses and Sales of Financial Assets Recovery of loans written off as losses increased from the previous quarter both in the Retail and the Wholesale business segment in Brazil. In the third quarter of 2025, portfolios already written off as losses were sold in the amount of R$1.1 billion, generating a positive impact of R$35 million on the recovery of loans and R$19 million on the recurring managerial result. These sales do not impact credit quality indicators. In the quarter, we recorded sales of active portfolios to unrelated companies with no retention of risk. Of these sales, R$122 million refer to active loans from the Wholesale business segment in Brazil that were more than 90 days overdue, of which R$71 million would still be active at the end of September 2025 if not for the sales. Additionally, we sold R$90 million (R$42 million from large companies, R$42 million from Latin America and R$6 million from individuals) from active portfolios that were not overdue. These sales of active portfolios had a negative impact of R$15 million on operating revenues, a negative impact of R$27 million on cost of credit, and a negative impact of R$23 million on recurring managerial result, with no material impact on credit quality indicators.

In Brazil, the ratio for individuals also remained stable at 3.6%, the highest level in the historical series. As expected, there was a 0.1 p.p. increase in the indicator for very small, small and middle market companies in Brazil, due to the normalization of the indicator as a consequence of the end of the grace period for government programs credit. In Latin America, the ratio decreased by 0.1 p.p., with a reduction of the overdue portfolio for individuals in Chile and for companies in Colombia. In total nonperforming loans 15 to 90 days overdue ratio (NPL 15-90) increased by 0.3 p.p. and closed the quarter at 2.0%. The ratio increased by 0.9 p.p. in the corporate segment in Brazil and closed the quarter at 1.0%. The increases both on a consolidated basis and in the corporate segment were due to a specific client that was adequately provisioned and already classified in stage 3. Excluding this effect, the ratios would have remained at the same levels of the previous quarter, that is, 1.7% on a consolidated basis and 0.1% in the corporate segment in Brazil. In very small, small and middle market companies in Brazil, there was a 0.1 p.p. increase in the ratio due to the end of the grace period of government programs credit. Still with respect to the short-term NPL ratio, the highlight was the loan portfolio for individuals in Brazil, which remained stable for another quarter at 3.0%. In Latin America, the ratio decreased due to the lower NPL ratio for companies in Chile, Colombia and Paraguay.

This portfolio consists of loan operations and securities with significant change in the terms of the contract, due to the deterioration of their credit quality, and reduced 2.8% compared to June 2025. The renegotiated loans and securities portfolio decreased 1.1% in the same period. NPL Creation remained basically stable compared to the previous quarter and closed the third quarter at R$9,485 million. The NPL creation over portfolio ratio remained at 0.7% at historically low levels. The ratio for the retail in Brazil remained at 1.5%, whereas the ratio for the Latin America portfolio is at historical lows. Loan portfolio write-off increased by 3.2% from the previous quarter. This increase is natural and related to portfolio growth, as the ratio between write-offs and the average credit portfolio balance remained stable at 0.7% in the quarter. The loan portfolio write-off was not impacted by the adoption of CMN Resolution No. 4,966/21.

Stage 2: Applicable to financial instruments with a significant increase in credit risk since their origination, with the following conditions: • Not problematic assets • A delay of between 30 and 90 days Stage 3: Applicable to assets with credit recovery problems (problematic assets), evidenced by a delay over 90 days in the payment of principal or charges, or by the indication that the respective obligation will not be fully honored. At this stage, the recognition of interest is on a cash basis. This stage is indicated by: • A delay over 90 days • Restructuring: renegotiation with significant change in the original conditions due to a relevant deterioration • Indication of non-compliance with obligations For further details, see explanatory note 2 b) of the Financial Statements. The credit portfolios classified as Stage 2 and Stage 3 remained at similar levels to those observed in the previous quarter, with no significant changes. It is worth noting that the specific client case that impacted the delinquency indicator between 15 and 90 days, which occurred in the large companies portfolio, was already adequately provisioned and classified as Stage 3. The reductions in coverage of Stage 2 and Stage 3 portfolios in Latin America are related to the improvement of ratings of specific corporate clients.

Another highlight was the higher gains from card issuing activities, as well as higher revenue from payments and collections, as a result of higher revenue from acquiring activities. Compared to the first nine months of 2024, commissions and fees and revenue resulting from insurance operations increased by 5.3%, without the effects of the adoption of CMN Resolution No. 4,966/21 starting in January 2025, the increase would be 6.0%. The growth was driven by (i) increase in revenue from card issuing activities, due to the higher credit card transaction volume; (ii) increase in payments and collections, due to higher revenue from acquiring activities and corporate current account packages; (iii) higher gains from asset management, both in funds and Consórcio management fees; and (iv) higher result from insurance operations due to higher earned premiums.

Revenue increased by 5.1% compared to the first nine months of 2024, mainly due to higher gains from interchange fees, as a result of the increase in the credit card transaction volume, partially offset by higher expenses on reward programs and the drop in revenue from annual fees, driven by the strategy of offering more benefits to clients as they increase their engagement with the Acquiring Transaction Volume 3Q25 R$257.7 billion +6.6% vs 2Q25 +12.8% vs 3Q24 Credit +7.9% vs 2Q25 +18.2% vs 3Q24 Debit +3.5% vs 2Q25 +1.4% vs 3Q24 Note: As from the first quarter of 2025, revenue from card activities – acquirer, in addition to corporate current account package fees, and Pix (the Central Bank of Brazil's instant payment system) are now allocated in the Payments and Collections line (previously Collection Services). For comparability purposes, previous periods were also reclassified. (1) Revenues from Insurance, Pension Plan and Premium Bonds Operations net of retained claims and selling expenses. Starting in the first quarter of 2025, the payments and collections line began to consolidate revenues from all collection products, including acquiring, and fees for corporate checking account packages, reflecting the strategy of integrating Rede with Itaú. The positive development is related to increased customer engagement with Itaú, resulting from the progress in the operational agenda and the complete value proposition with integrated banking, acquiring, and credit journeys. The increases of 3.7% in the quarter and of 6.1% compared to the first nine months of 2024 were mainly driven by higher gains from cash advances in acquiring services, higher transaction volume, and higher revenue from corporate current account packages in the year to date.

Compared to the first nine months of 2024, revenue from current account services for individuals decreased by 15.9%. In both comparisons, the reduction was driven by our proactive agenda of offering increasingly better conditions to clients, as they improve their relationship with the bank. Advisory Services and Brokerage Revenue from advisory and brokerage services increased 33.7% from the previous quarter, due to higher volumes in fixed income transactions. Compared to the first nine months of 2024, this revenue decreased 14.6%. Fixed Income: In 3Q25, in local fixed income, we were ranked 1st in ANBIMA’S origination ranking, totaling R$36.9 billion in originated volume with a 26.7% market share, and ranked 2nd in ANBIMA’S distribution, totaling R$17.0 billion in distributed volume with a 20.0% market share. Result from Insurance, Pension Plan and Premium Bonds Compared to the previous quarter, the results from insurance, pension plan and premium bonds increased by 5.7%, mainly due to the increase in managerial financial margin, driven by the higher return on our assets and higher earnings from affiliates. On the other hand, there was an increase in retained claims, mainly due to the growth in life, and credit life segments. Current Account for Individuals Fund Management Fund management fees decreased by 4.5% compared to the previous quarter, due to lower gains from performance fees, as a result of concentrating the recognition of these revenues in the second and fourth quarters of the year, partially offset by the greater number of business days in the third quarter. Compared to the first nine months of the previous year, fund management fees grew by 7.8%, mainly due to the increase in the balance and the gains from performance fees, which were partially offset by the fewer number of business days in the period (188 x 190 business days). +10.1% +3.2% Equities: In 3Q25, we entered into 3 transactions, totaling R$497.7 million in volume (a 7.5% market share), ranking 2nd in number of transactions and 3rd in volume of transactions in Dealogic’s ranking. Mergers and Acquisitions: In 3Q25, we provided financial advisory services on 7 transactions in Brazil, totaling R$6.0 billion (a 15.8% market share), ranking 4th in number of transactions and 5th in volume of transactions in Dealogic’s ranking. Excluding proprietary operations, we provided financial advisory services on 7 transactions in Brazil totaling R$6.0 billion (a 17.8% market share), ranking 2nd in number of transactions and 4th in volume of transactions in Dealogic’s ranking. +5.7% +17.8% 3Q25 x 2Q25 R$3.0 bn 3Q25 x 3Q24 Compared to the first nine months of 2024, the result from insurance, pension plan and premium bonds increased by 17.1%, mainly due to higher premiums earned from life, credit life, protected card and mortgage insurance lines, and to the increase in commissions and fees, focused in pension plan and third-party insurance commissions.

This increase was mainly related to the effects of the negotiation of the collective wage labor agreement, with a 5.68% adjustment to salary beginning in September, which also impacted vacation and year-end bonus provisions. The collective wage labor agreement affects the expense lines for the Commercial and Administrative, Transactional, and Technology areas. In addition to the effects mentioned above, transactional expenses increased due to higher expenses on card brands but were partially offset by the reduction in expenses on physical spaces, driven by lower rental expenses, as a result of the optimization of the network of brick-and-mortar branches, which recorded an annual reduction of 12.6%. Technology expenses also increased, due to higher expenses for system development. Our quarterly efficiency ratio reached 37.7% in Brazil, a decrease of 0.9 p.p. on a year-onyear basis, reaching the lowest level in the historical series for a third quarter. In Latin America, non-interest expenses grew by 0.6% compared to the previous quarter. Compared to the first nine months of 2024, non-interest expenses were up by 8.9%. The strategic investments in technology drove the 20.4% increase in expenses. Personnel expenses, that impact Commercial and Administrative, Transactional e Technology expenses, increased due to the effects of the negotiation of the collective wage labor agreement. In Latin America, the increase was mainly driven by foreign exchange variation and by higher personnel and technology expenses in Chile.

These changes were due to the increases in deposits received under securities repurchase agreements, time deposits and pension plan funds. Additionally, loan operations increased by R$11.8 billion for all segments of the Brazilian portfolio. The increase of 3.8% compared to January 1, 2025* was mainly driven by the increase of R$71.2 billion in securities, focused on government securities and of R$32.2 billion in interbank investments. Liabilities increased in the quarter, mainly driven by the increases of: (i) R$47.9 billion in deposits received under securities repurchase agreements; (ii) R$19.8 billion in deposits, due to the increase in time deposits; (iii) R$12.7 billion in other liabilities, due to the increase in liabilities related to payment transactions; and (iv) R$11.7 billion in technical provisions for insurance, pension plans and premium bonds, due to the higher net gain on funds and higher return on provisions for pension plans. The 3.8% increase in liabilities compared to January 1, 2025* was due to the increase of R$71.1 billion in deposits received under securities repurchase agreements and of R$36.2 billion in technical provisions for insurance, pension plans and premium bonds, mainly driven by the net gain on funds and the increase in return on provisions for pension plans.

The 5.9% increase in the last 12 months was due to an increase of R$47.6 billion in funds from bills, structured operations certificates and repurchase agreements, which was also concentrated in real estate and agribusiness bills, and to an increase of R$28.8 billion in time deposits in Brazil, driven by portfolio growth due to the higher interest rates. Assets under management and administration grew by 3.1% in the quarter. The 10.4% increase in the last 12 months was the result of increases of 11.4% in own products and 13.2% in the open platform, driven by the rise in pension plan funds, Bank Deposit Certificates and Real Estate Credit Notes.

(2) Excluding the exchange rate variation of the period, which was considered in the column of prudential and equity adjustments together with the capital index hedge. (3) The issuance of the Perpetual Subordinated Financial Bills described in the announcement to the market dated October 8, 2025, will take the AT1 to 1.5%, considering the limit set by CMN Res. No. 4,958. Without this limit, the AT1 would be 1.6%. Capital Ratios Main changes in the quarter (1) Considering the limit of 1.5% for AT1, according to CMN Res. No. 4,958. Without this limit, the Tier I Capital Ratio would be 15.0% in Jun-25. Note: The ratios were calculated based on the Prudential information, which includes financial institutions, consórcio managers, payment institutions, companies that acquire operations or which directly or indirectly assume credit risk and investment funds in which the conglomerate retains substantially all of the risks and benefits. Referential Equity: increased by 0.4% driven by the net income of the period, offset by the AT1 buyback in September 2025. RWA: increased by R$17.9 billion, mainly due to the increase in credit risk (RWACPAD). BIS ratio: decreased by 0.1 p.p. from June 2025, mainly due to the AT1 buyback and the growth in RWA, despite the positive net income of the period. In September 2025, the BIS ratio was 4.8 p.p. above the minimum required, with capital buffers. Liquidity Ratios These ratios are calculated based on the methodology defined by the Brazilian Central Bank, which is in line with the Basel III international guidelines. Liquidity Coverage Ratio (LCR) The average LCR in the quarter reached 218.7%, above the 100% limit, which means that we have sufficient resources consistently available to cover losses in stress scenarios. Net Stable Funding Ratio (NSFR) The NSFR was 123.3% at the end of the quarter, above the 100% limit, which means that we have stable resources available to support the stable resources required in the long term. For 2025, the minimum liquidity ratio indicator required by the Brazilian Central Bank is 100%. Value at Risk - VaR1 This is one of the main market risk indicators, and a statistical metric that quantifies the potential economic losses which are expected in normal market conditions. (1) Values represented above consider a 1-day time horizon and a 99% confidence level.

On the other hand, the financial margin with clients decreased, due to the higher average credit volume, mainly driven by government programs for small companies. Another highlight was the increase in revenue from insurance operations. The recurring managerial result was up by 25.4% on a year-on-year basis, due to the higher financial margin with clients, driven by the better mix of products and the increase in the average credit volume, in addition to the higher revenue from insurance operations, driven by the increase in earned premiums. On the other hand, cost of credit grew as a result of higher expected loss expenses and the increase in discounts granted.

The recurring managerial result rose by 7.4% on a year-on-year basis, mainly driven by a higher financial margin with clients, due to the increase in the average credit volume and the higher liabilities margin, and by the increase in commissions and fees, due to higher gains from fund management and investment banking.

Results by Region We present below the income statement segregated between our operations in Brazil, which includes units abroad, excluding Latin America, and our operations in Latin America (excluding Brazil). • Our operations in Brazil¹ represent 93.3% of the recurring managerial result for the quarter. • Our operations in Latin America achieved a ROE of 15.5%. Brazil¹ (in R$ million, end of period) Latin America (in R$ million, end of period) Main foreign exchange variations compared to the Brazilian Real (BRL) - September, 2025 (1) Includes units abroad, ex-Latin America. (2) The result from Insurance includes Revenue from Insurance, Pension Plans and Premium Bond Operations before Retained Claims and Selling Expenses. (3) Includes Tax Expenses (ISS, PIS, COFINS and other) and Insurance Selling Expenses. (4) The Annualized Recurring Managerial Return was calculated by dividing the Recurring Managerial Result by the Average Stockholders’ Equity. This result was then multiplied by the number of periods in the year to derive the annualized rate. Note: Information for Latin America is presented in the nominal currencies.

Managerial Financial Margin The sum of the Financial Margin with Clients and the Financial Margin with the Market. Recurring Managerial Return on Average Equity – Annualized Obtained by dividing the Recurring Managerial Result by the Average Stockholders’ Equity. The resulting amount is multiplied by the number of periods in the year to derive the annualized rate. The calculation bases of returns were adjusted by the dividends proposed after the balance sheet closing dates, which have not yet been approved at the annual Stockholders' or Board meetings. Recurring Managerial Return on Average Assets – Annualized Obtained by dividing the Recurring Managerial Result by the Average Assets. Coverage by Stage Obtained by dividing the expected loss provision of the stage by the balance of operations of the respective stage. Efficiency Ratio Obtained by dividing the Non-Interest Expenses by the sum of Managerial Financial Margin, Commissions and Fees, Result of Insurance, Pension Plan and Premium Bonds Operations and Tax Expenses (ISS, PIS, COFINS and Other Taxes). Recurring Managerial Result per Share Calculated based on the weighted average number of outstanding shares for the period, including stock splits when they take place. Dividends and Interest on Own Capital Net of Taxes Corresponds to the distribution of a portion of the profits to stockholders, paid or provisioned, declared and posted in Stockholders' Equity. Market Capitalization Obtained by multiplying the total number of outstanding shares (common and nonvoting shares) by the average price per non-voting share on the last trading day of the period. Tier I Capital Ratio The sum of the Common Equity Tier I and the Additional Tier I Capital, divided by the Total Risk Weighted Assets. Cost of Credit Composed of the Result from Loan Losses, Discounts Granted and recovery of loans written of as losses. Annualized average rate of financial margin with clients Obtained by dividing the Financial Margin with Clients by the average daily balances of spread-sensitive operations, working capital and others. This figure is divided by the number of calendar days in the quarter and annualized (rising to 360) to obtain the annual rate. Executive Summary Managerial Financial Margin Financial margin with clients Consists of spread-sensitive operations, working capital and others. Spreadsensitive operations include: (i) the margin on assets, which is the difference between the amount received from loan operations and corporate securities and the cost of money charged by treasury banking, and (ii) the liabilities margin, which is the difference between the cost of funding and the amount received from treasury banking. The working capital margin is the interest on working capital at a fixed interest rate. Financial margin with the market Includes treasury banking, which manages mismatches between assets and liabilities - Asset and Liability Management (ALM), terms, the rates of interest, foreign exchange and others, and treasury trading, which manages proprietary portfolios and may assume guiding positions, in compliance with the limits established by our risk appetite. Mix of Products Change in the composition of credit risk assets between periods. Average asset portfolio Includes the portfolio of credit and private securities, net of loans more than 60 days overdue, but excluding the effects of average exchange rate variations during the periods. Asset spreads Variations in the spreads on credit risk assets between periods. Credit Quality NPL Ratio (over 90 days) Calculated by dividing the balance of loans which have been non-performing for longer than 90 days by the total loan portfolio. Loans overdue for more than 90 days include the total balance of transactions with at least one installment more than 90 days overdue. NPL Creation The balance of loans that became more than 90 days overdue during the quarter. Cost of Credit over Total Risk Calculated by dividing the Cost of Credit by the average value of the Loan Portfolio for the last two quarters. Commissions and Fees and Insuran- Underwriting Margin The sum of earned premiums, retained claims and selling expenses. Combined Ratio The sum of retained claims, selling expenses, administrative expenses, other operating income and expenses, tax expenses for ISS, PIS and COFINS and other taxes divided by earned premiums. 32 Loan-to-Value Ratio of the financing amount to the value of the underlying real estate. Credit Portfolio Funding Loan Portfolio over Gross Funding Obtained by dividing Loans by Gross Funding (Funding from Clients, Funds from Acceptance and Issuance of Securities Abroad, Borrowing and Others) at the end of the period. Currency Includes cash, bank deposits of institutions without reserve requirements, foreign currency deposits in Brazil, foreign currency deposits abroad, and cash and cash equivalents denominated in foreign currency. Capital, Liquidity and Market Indicators Value at Risk (VaR) A statistical metric that quantifies the potential economic loss to be expected in normal market conditions. The consolidated VaR of Itaú Unibanco is calculated based on a Historical Simulation of the bank’s total exposure to market risk, at a confidence level of 99%, a historical period of four years (1000 business days) and a holding period of one day. In addition, using a conservative approach, the VaR is calculated daily, whether volatilityweighted or not, and the final VaR is whichever of the two methodologies is the most restrictive. Common Equity Tier I The sum of social capital, reserves and retained earnings, less deductions and prudential adjustments. Additional Tier I Capital Consists of instruments of a perpetual nature, which meet the eligibility requirements. Tier I Capital The sum of the Common Equity Tier I and the Additional Tier I Capital. Tier II Capital Consists of subordinated debt instruments with defined maturity dates that meet the eligibility requirements. Total Capital The sum of the Tier I and Tier II Capital. Total Risk Weighted Assets Consists of the sum of the portions related to the credit risk exposur (RWACPAD), the market risk capital requirement (RWAMINT) and the operational risk capital requirement (RWAOPAD). Results by Business Segment Retail Business Consists of the offering of banking products and services to both current account and non-current account holders. Products and services offered include: personal loans, credit cards, payroll loans, vehicle financing, mortgage loans, insurance, pension plan and premium bond products, and acquiring services, among others.

Itaú Day was attended by the Co-chairmen of the Board of Directors and all members of the Executive Committee. More than 35,000 people have already watched the event, which is available on our Investor Relations website. Performance 9M25 X 9M24 Financial Margin with Clients R$90.2 billions 38.8% Efficiency Ratio 14.8% Tier 1 Capital Ratio3 -30 bps -40 bps The total credit portfolio growth was 6.4% compared to the previous year. The increase of the credit portfolio in Brazil was 7.8% and occurred in all segments: 6.5% in individuals, 7.5% in very small, small and middle market loans and 9.4% in corporate loans. The portfolio in Latin America decreased 0.3%, and excluding exchange rate variation for the period, this portfolio would have grown 4.5%. The positive effect of the growth in the credit portfolio, the higher liabilities’ margin , in addition to the higher remuneration of our working capital, led to a growth of 13.4% in the financial margin with clients. Commissions and fees and result from insurance operations rose by 5.3%, mainly due to the higher revenues with card-issuing activities, in addition to higher gains with asset management and with payments and collections. It is also worth highlighting the increase of 17.1% in the result from insurance, pension plan and premium bonds. Non-interest expenses rose by 8.9%, due to strategic investments in technology and to the effects of negotiating the collective wage agreement. Our accumulated efficiency ratio in the first nine months of 2025 reached 38.8% on a consolidated basis and 36.9% in Brazil, representing reductions of 30 bps and 70 bps, respectively, compared to the same period of the previous year.

Note 2 - Material accounting policies a) Basis of preparation The financial statements of ITAÚ UNIBANCO HOLDING and its subsidiaries (ITAÚ UNIBANCO HOLDING CONSOLIDATED) have been prepared in accordance with the Brazilian Corporate Law, as amended by Laws 11,638, of December 28, 2007, and 11,941, of May 27, 2009, and in compliance, when applicable, with instructions issued by the National Monetary Council (CMN), the Central Bank of Brazil (BACEN), the Brazilian Securities Commission (CVM), the National Council of Private Insurance (CNSP) and the Superintendence of Private Insurance (SUSEP). The information in the financial statements and accompanying notes evidences all relevant information inherent in the financial statements, and only them, which is consistent with information used by management in its administration. ITAÚ UNIBANCO HOLDING opted for presenting its Condensed Consolidated and Individual Financial Statements, including selected accompanying notes, in accordance with current regulations. ITAÚ UNIBANCO HOLDING adopted on January 1, 2025, CMN Resolution No. 4,966/21 that changes the accounting criteria applicable to financial instruments and opted for the exemption from presentation, in the Condensed Consolidated and Individual Financial Statements, of the comparative amounts related to previous periods, as set forth in Article 79 of this Resolution. In order to allow better understanding of these Condensed Consolidated and Individual Financial Statements, supplementary information was included in the Condensed Consolidated Balance Sheet and Condensed Consolidated and Individual Statement of Changes in Stockholders’ Equity, that corresponds to the balances on December, 31, 2024, adjusted with new concepts at the initial date of effectiveness of CMN Resolution No. 4,966/21. Further information on the effects of the regulatory transition is detailed in Note 2b I. The presentation of the Statements of Added Value is required by the Brazilian corporate legislation and by the accounting practices adopted in Brazil applicable to publicly-held companies. This Statement was prepared in accordance with the criteria established by Technical Pronouncement CPC 09 - Statement of Added Value. 57 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 b) Changes in new accounting standards and interpretations of existing standards I - Applicable for period ended September 30, 2025 • CMN Resolution No. 4,966/21 - Financial Instruments - Establishes the classification, measurement, recognition and write-off of financial instruments, recognition of a provision for expected credit loss associated with credit risk and designation and accounting recognition of hedge accounting. Adoption was prospective, with no material effects, as of January 1, 2025, with the exception of hedge accounting and adjustment to the present value of restructured financial instruments whose effectiveness will be on January 1, 2027. CMN Resolution No. 4,966/21 considers the following pillars: Classification and measurement of financial instruments: the Securities classification categories that where previously Held to Maturity, Available for Sale and Held for Trading and no longer exist, and three measurement categories are introduced for all financial assets: • Amortized cost (AC): used when financial assets are managed to obtain contractual cash flows, consisting only of principal and interest payments. A significant portion of the financial assets previously classified as Held to Maturity and Available for Sale has been accounted for in this category, in addition to Credit Operations and Other Credits. • Fair value through other comprehensive income (FVOCI): used when financial assets are held both to obtain contractual cash flows, consisting only of principal and interest payments, and for sale. The remaining portion of financial assets previously accounted for as Available for Sale was classified in this category. • Fair value through profit or loss (FVPL): used for financial assets that do not meet the criteria described above. Derivatives, financial assets Held for Trading and equity instruments were recorded in this category. Two criteria should be considered to determine the classification of the financial assets described above: • Business model definition: that reflects how financial instruments are managed to achieve a specific commercial objective and generate cash flows, not depending on the management’s intentions in relation to an individual instrument. • Characteristics of contractual cash flow: they are tested individually to validate whether they meet the criteria for payment of only principal and interest. In the initial adoption there were designation of equity instruments at fair value through other comprehensive income whose ITAÚ UNIBANCO HOLDING CONSOLIDATED’s objective is not to generate return from their sale, since they mainly refer to companies for the development of the market in which it operates. Additionally, with the objective of eliminating accounting asymmetries, there was a designation of financial assets at fair value through profit or loss that are part of the market risk management strategy. ITAÚ UNIBANCO HOLDING CONSOLIDATED kept the measurement of financial liabilities, which remains measured at amortized cost, except for Derivatives, which are measured at fair value through profit or loss. Financial instruments measured at AC and FVOCI use the effective interest method to calculate interest income or expense, considering the materiality aspects of transaction costs in origination. To calculate the effective interest rate of credit operations with credit granting characteristics classified in AC category, ITAÚ UNIBANCO HOLDING CONSOLIDATED adopted a differentiated methodology for recognition of revenues and expenses related to transaction costs. Provision for expected credit loss associated with credit risk: includes the use of prospective information and classification of financial instruments in three stages: 58 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 • Stage 1 - credit loss expected for the next 12 months. Applicable to financial instruments without significant increase in credit risk. ITAÚ UNIBANCO HOLDING CONSOLIDATED did not adopt the option to calculate the expected credit loss for the entire life of financial instruments at this stage. • Stage 2 - expected credit loss over the life of the financial instrument. Applicable to financial instruments with a significant increase in credit risk since their origination. • Stage 3 - expected credit loss over the life of the financial instrument. Applicable to assets with credit recovery problems (problem assets), evidenced by the delay over 90 days in the payment of principal or charges or by the indication that the respective obligation will not be fully honored. At this stage, the recognition of interest is on cash basis. A financial instrument will migrate of stage as its credit risk increases or decreases. ITAÚ UNIBANCO HOLDING CONSOLIDATED did not recognize the interest of the operations that, in the transition, were past due for over 60 days and were not characterized as problem assets.

In ITAÚ UNIBANCO HOLDING, the new classifications of financial instruments did not produce any effect on Stockholders’ equity in the initial adoption of CMN Resolution No. 4,966/21. The classification involved the transfer of financial assets previously classified as Available for sale securities at a Fair value through profit of loss in the amount of R$ 2. In relation to expected credit loss associated with credit risk, there was an increase in Assets of R$ 1,638, as a counterparty to Stockholders’ equity, which corresponds to R$ 652, net of tax effects. In addition, there were net reflective impacts of associates and subsidiaries on Stockholders’ equity of R$ (271). ITAÚ UNIBANCO HOLDING CONSOLIDATED would have recognized in Income or Other Comprehensive Income the amount of R$ 1,371 during the period from 01/01/2025 to 09/30/2025 if the financial instruments had not been reclassified of category. 12/31/2024 01/01/2025 01/01 to 09/30/2025 Gains/(Losses) of unrecognized fair value adjustment Fair value Classification Income Other comprehensive income Securities 840,986 AC - 1,371 FVOCI - - 60 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 Regarding the provisions for expected credit loss from financial instruments, ITAÚ UNIBANCO HOLDING CONSOLIDATED presents a summary of the changes made: Financial instruments 12/31/2024 01/01/2025 Rating Accounting balance Impairment Stage Gross accounting balance Provision for Expected credit loss Securities N/A 849,002 (616) 1 292,498 (110) 2 241 (1) 3 1,595 (1,195) N/A (1) 554,726 - Total 849,002 (616) 849,060 (1,306) AA 558,075 (1,720) A 262,116 (2,185) B 118,618 (3,257) C 32,559 (3,253) Credit operations D 8,600 (2,579) E 5,240 (2,620) F 6,331 (4,431) G 5,485 (5,452) H 25,054 (25,054) N/A 188,540 (3,549) 1 1,098,610 (9,958) 2 56,770 (13,068) 3 55,238 (30,345) Total (2) 1,210,618 (54,100) 1,210,618 (53,371) Financial guarantees, credit commitments and credits to be released (3) 1 611,267 (337) 623,730 (1,045) 2 8,509 (124) 3 3,954 (692) Total 623,730 (1,045) 623,730 (1,153) 1) Financial assets not subject to expected credit loss, composed of government securities classified in the FVPL category measured at level 1 of the fair value hierarchy and by equity instruments (FVPL or FVOCI). 2) On January 1, 2025, the provision for expected credit loss comprises R$ 47,983 relating to credit operations, lease and other credits with credit granting characteristics and R$ 5,388 related to securities with credit granting characteristics. 3) The amounts are recorded off-balance sheet. • CMN Resolution No. 4,975/21 - Lease - Receives the Accounting Pronouncement (CPC) 06 (R2) - Leases that eliminate the accounting of operating leases for the lessee, presenting a single lease model, which consists of: (a) initially recognize all leases as a right of use and the respective obligation at present value; and (b) recognize the depreciation of the right of use and the interest on the lease separately in income. Transition to CMN Resolution No. 4,975/21 ITAÚ UNIBANCO HOLDING has adopted the Accounting Pronouncement (CPC) 06 (R2) - Lease, prospectively, since January 1, 2025, using the following criteria: (1) unified discount rate, considering a portfolio of similar contracts; and (2) calculation of the Right-of-use asset and lease liability for new contracts signed in which ITAÚ UNIBANCO HOLDING appears as a lessee, as from the effectiveness of the standard. II - Applicable to future periods • CMN Resolution No. 4,966/21 - Financial instruments and related regulations - Establishes the designation and accounting recognition of hedge and adjustment to the present value of restructured financial instruments, being in force starting January 1, 2027. Possible impacts are being evaluated and will be completed by the date of the standard effectiveness. c) Accounting policies, critical estimates and material judgments This note presents the main critical estimates and judgments used in the preparation and application of ITAÚ UNIBANCO HOLDING CONSOLIDATED’s specific accounting policies. These estimates and judgments present a material risk and may have a material impact on the values of assets and liabilities due to uncertainties and the high level of subjectivity involved in the recognition and measurement of certain items. Therefore, actual results may differ from those obtained by these estimates and judgments. 61 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 I - Consolidation The consolidated financial statements of ITAÚ UNIBANCO HOLDING CONSOLIDATED comprise the transactions carried out by its branches and subsidiaries in Brazil and abroad, including investment funds, in which ITAÚ UNIBANCO HOLDING CONSOLIDATED holds either direct or indirect control. The main judgment exercised in the control assessment is the analysis of facts and circumstances that indicate whether ITAÚ UNIBANCO HOLDING CONSOLIDATED is exposed or is entitled to variable returns and has the ability to affect these returns through its influence over the entity on a continuous basis. The consolidated financial statements are prepared using consistent accounting policies. Intercompany asset and liability account balances, income accounts and transaction values have been eliminated. In ITAÚ UNIBANCO HOLDING, goodwill recorded in subsidiaries is amortized based on the expected future profitability and appraisal reports, or upon realization of the investment, according to the rules and guidance of CMN and BACEN. The difference in Net Income and Stockholders’ Equity between ITAÚ UNIBANCO HOLDING and ITAÚ UNIBANCO HOLDING CONSOLIDATED (Note 18d) results substantially from the adoption of different criteria for the amortization of goodwill originating from acquisitions of investments, for recognizing transactions with minority shareholders where there is no change in control, prior to January 1, 2022, and for recognizing foreign exchange differences, prior to January 1, 2017, on foreign investments and hedging these investments, which are denominated in currencies other than the functional currency of the parent company, net of the corresponding tax effects. The effects of foreign exchange differences on foreign investments are classified under the heading Income on Securities, Derivative Financial Instruments and Other in the Statement of Income for subsidiaries with the same functional currency as the parent company, and in Other Comprehensive Income for subsidiaries with a different functional currency. In conformity with CPC 23 - Accounting Policies, Changes in Accounting Estimates and Errors, and with the purpose of maintaining the quality and reliability of the financial statements, in addition to providing a more appropriate representation of the equity position, financial performance and cash flows, ITAÚ UNIBANCO HOLDING CONSOLIDATED adopted the accounting policy for correcting, starting July 1, 2023, the financial statements of its controlled companies located in hyperinflationary economies in accordance with CPC 42 - Financial Reporting in Hyperinflationary Economies. The following table shows the main consolidated companies, which together represent over 95% of total consolidated assets, as well as the interests of ITAÚ UNIBANCO HOLDING in their voting capital: 62 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 Functional currency (1) Incorporation Country Activity Interest in voting capital % Interest in total capital % 09/30/2025 09/30/2025 In Brazil Banco Itaú Consignado S.A.

Miami Branch, which functional currency is the US Dollar. 63 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 I.I - Business combinations When accounting for business combinations, ITAÚ UNIBANCO HOLDING CONSOLIDATED exercises judgments in the identification, recognition, and measurement of: price adjustments; contingent considerations; and options or obligations to buy or sell ownership interest of the acquired entity. Non-controlling shareholders’ ownership interest is measured on the date of acquisition according to the proportional interest in Stockholders’ equity of the acquired entity. I.II - Capital transactions with non-controlling stockholders Changes in an ownership interest in a subsidiary, which do not result in a loss of control, are accounted for as capital transactions and any difference between the amount paid and the carrying amount of non-controlling stockholders is recognized directly in Stockholders' equity. II - Functional and presentation currency The consolidated financial statements of ITAÚ UNIBANCO HOLDING CONSOLIDATED are presented in Brazilian Reais, which is its functional and presentation currency. For each subsidiary, associate and joint venture, ITAÚ UNIBANCO HOLDING CONSOLIDATED exercised judgment to determine its functional currency, considering the currency of the primary economic environment in which the entity operates. Foreign currency operations are translated using the exchange rates prevailing on the dates of the transactions, and exchange gains and losses are recognized in the Statement of Income. For conversion of the financial statements of foreign entities with a functional currency other than Reais, ITAÚ UNIBANCO HOLDING CONSOLIDATED uses the exchange rate on the closing date to convert assets and liabilities, and the average monthly exchange rate to convert income and expenses, except for foreign entities located in hyperinflationary economies. Exchange differences generated by this conversion are recognized in Other Comprehensive Income, net of tax effects, and reclassified, either in total or partially, to income when ITAÚ UNIBANCO HOLDING CONSOLIDATED loses control of the foreign entity. The ITAÚ UNIBANCO HOLDING CONSOLIDATED conducts hedge of net investment in foreign operation, whose effective portion is recognized in Stockholders’ Equity. III - Cash and cash equivalents They are defined as cash and cash equivalents, current accounts with banks and financial investments, which are promptly convertible into cash, this is, which original term is equal to or lower than 90 days and are subject to an insignificant risk of change in value, shown in the Balance Sheet under the headings Cash, Interbank deposits and Securities purchased under agreements to resell (Collateral held). IV - Financial assets and liabilities Financial assets and liabilities are initially recognized at fair value on the trading date. Financial assets are written off, if: • the contractual rights to the cash flows of the financial asset expire. • there are no reasonable expectations of its recovery. In this case, the write-off is carried out simultaneously with the use of the related provision for expected credit loss and collection procedures are maintained. Subsequent recoveries are accounted for as revenue as a counterparty to asset, with the constitution of their respective provision for expected credit loss. • ITAÚ UNIBANCO HOLDING CONSOLIDATED transfers substantially the risks and benefits of the financial asset. The main judgments exercised by ITAÚ UNIBANCO HOLDING CONSOLIDATED in the write-off of financial assets are: assessment of the time when contractual rights to cash flows of financial assets expire; reasonable expectation of recovery of the financial asset, and substantial transfer of risks and benefits or control. 64 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 When the contractual cash flow of a financial asset is renegotiated or otherwise modified, ITAÚ UNIBANCO HOLDING CONSOLIDATED evaluates whether the renegotiation event is characterized as a restructuring, this is, whether there has been a significant concession to the counterparty, due to the deterioration of the client’s credit quality. The gross book value of the renegotiated financial assets is recalculated with the new conditions agreed upon. Financial liabilities are written off when extinguished, this is, when the obligation specified in the contract is settled, canceled, matured or expired. IV.I - Classification of financial assets The classification and subsequent measurement of financial assets are detailed in Note 2b I . Hybrid contracts: to identify if a contract contains embedded derivatives, ITAÚ UNIBANCO HOLDING CONSOLIDATED considers especially if there is any indexing to different components of interest and uncertainty regarding the link with the final indexing. Hybrid contracts in which the main component is a financial asset are accounted for on a jointly basis, this is, the whole instrument (principal and derivative component) is measured at fair value through profit or loss. In other cases, embedded derivatives are treated as separate financial instruments if: their characteristics and economic risks are not closely related to those of the main component; the separate instrument meets the definition of a derivative; and the underlying instrument is not booked at fair value through profit or loss. Equity instruments: the shares and quotas are classified at fair value through profit or loss, except when the financial instrument is held with a purpose other than its trading, situation in which ITAÚ UNIBANCO HOLDING CONSOLIDATED designates it, on an irrevocable basis, at fair value through other comprehensive income. IV.II - Classification of financial liabilities Financial liabilities are subsequently measured at amortized cost, except for: • Financial liabilities at fair value through profit or loss: classification applied to derivatives and financial liabilities generated in loans or rental of financial assets. • Credit commitments and Credits to be released. • Financial guarantees: measured by the greater amount between (i) the provision for expected credit loss; and (ii) the balance of the service fee to be deferred in income, according to the contract term. IV.III - Subsequent measurement of financial instruments Fair value of financial instruments: to measure fair value, assessment techniques applying information classified in three levels of hierarchy are used, prioritizing prices listed in active markets of the instruments. ITAÚ UNIBANCO HOLDING CONSOLIDATED classifies this information according to the relevance of data observed in the fair value measurement process: Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. An active market is a market in which transactions for the asset or liability being measured occur often enough and with sufficient volume to provide pricing information on an ongoing basis. Level 2: Inputs that are not observable for the asset or liability either directly or indirectly. Level 2 generally includes: (i) quoted prices for similar assets or liabilities in active markets; (ii) quoted prices for identical or similar assets or liabilities in markets that are not active, that is, markets in which there are few transactions for the asset or liability, the prices are not current, or quoted prices vary substantially either over time or among market makers, or in which little information is released publicly; (iii) inputs other than quoted prices that are observable for the asset or liability (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, etc.); (iv) inputs that are mainly derived from or corroborated by observable market data through correlation or by other means. 65 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 Level 3: Inputs that are not observable for the asset or liability allowing the use of internal models and techniques. The portion of variation in the fair value of derivative financial liabilities measured at levels 2 or 3, resulting from changes in the own credit risk of ITAÚ UNIBANCO HOLDING CONSOLIDATED is recognized in Other Comprehensive Income, at the net amount of tax effects. To determine the gains and losses realized in the disposal of financial assets at fair value, average cost is used, which are recorded in the Consolidated Statement of Income as Securities, Derivatives and Other and Financial Income from Assets Guaranteeing Technical Provisions. For financial instruments measured at fair value on a recurring basis, including derivatives, that are not traded in active markets, the fair value is calculated by using valuation techniques based on assumptions, that consider market information and conditions. The estimated fair value obtained through these techniques cannot be substantiated by comparison with independent markets and, in many cases, cannot be realized on immediate settlement of the instrument. The main assumptions considered to estimate the fair value are: historical database, information on similar transactions, discount rate and estimate of future cash flows. The main judgments applied in the calculation of the fair value of more complex financial instruments, or those that are not negotiated in active markets or do not have liquidity, are: determining the model used with the selection of specific inputs and, in certain cases, evaluation adjustments are applied to the model amount or price quoted for financial instruments that are not actively traded. The application of these judgments may result in a fair value that is not indicative of the net realizable value or future fair values. However, ITAÚ UNIBANCO HOLDING CONSOLIDATED believes that all the methodologies adopted are appropriate and consistent with other market participants. The fair value of financial instruments as well as the hierarchy of fair value are detailed in Note 17. Amortized cost: is the amount at which the financial asset or liability is measured at initial recognition, plus adjustments made under the effective interest rate method, less repayments of principal and interest, and any provision for expected credit loss. ITAÚ UNIBANCO HOLDING CONSOLIDATED uses the effective interest rate method to calculate interest income or expense for financial instruments at amortized cost and through other comprehensive income, which considers costs and fees directly attributable to the origination of the contract, such as commissions paid or received by the parties to the contract, transaction costs and other premiums and discounts when exceeding 1% of the instrument's total revenues or charges. Additionally, ITAÚ UNIBANCO HOLDING CONSOLIDATED adopted the differentiated methodology for financial assets with credit granting characteristic classified in the amortized cost category. For liabilities classified in the amortized cost category, incremental costs and revenues are deferred by the effective interest rate curve. ITAÚ UNIBANCO HOLDING CONSOLIDATED classifies financial instruments as problem assets if the payment of principal or interest is overdue for over 90 days or indicates that the obligation will not be honored under the conditions agreed. In this case, the appropriation of interest starts being recognized on the cash basis. Expected credit loss: The main judgments exercised of ITAÚ UNIBANCO HOLDING CONSOLIDATED to calculate the expected credit loss are: selection of quantitative models to assess the expected credit loss; determination of triggers to significantly increase or decrease credit risk; identification and grouping of portfolios with similar credit risk characteristics; establishment of the maximum contractual period for assets with no determined maturity; determination of prospective information, macroeconomic scenarios and probability-weighted scenarios. 66 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 For makes an assessment of the expected credit loss on financial instruments (except equity instrument, derivatives, government securities measured at fair value through profit or loss at level 1 of the hierarchy of fair value) and to credit commitments and non-cancellable credits to be released, applying a three-stage approach to demonstrate changes in credit risk. • Stage 1 – considers default events possible within 12 months. Applicable to financial assets which are not credit impaired when purchased or originated or which credit risk has decreased significantly. • Stage 2 – considers all possible default events over the life of the financial instrument. Applicable to financial instruments which credit risk has increased significantly since the initial recognition or that no longer have credit recovery problems, but their credit risk has not decreased significantly. • Stage 3 – applicable to problem assets, for which a probability of default (PD) of 100% is considered. The assessment of expected credit loss is detailed in Note 2b I. The measurement of expected credit loss requires the application of significant assumptions and use of quantitative models. Management exercises its judgment in the assessment of the adequacy of the expected loss amounts resulting from models and, according to its experience, makes adjustments that may result from certain clients' credit status or temporary adjustments resulting from situations or new circumstances that have not been reflected in the modeling yet. The main assumptions considered to estimate the expected credit loss are: • Determining criteria for significant increase or decrease in credit risk: ITAÚ UNIBANCO HOLDING CONSOLIDATED determines triggers (indicators) of significant increase in the credit risk of a financial asset since its initial recognition on an individual basis and, in the case of retail portfolios, collectively. For collective assessment purposes of retail portfolios, financial assets are grouped based on similar characteristics of shared credit risk, considering the type of instrument, credit risk classifications, initial recognition date, remaining term, guarantees, among other significant factors. For wholesale business portfolios, the assessment is conducted on an individual basis. The migration of the financial asset to an earlier stage occurs with a consistent reduction in credit risk, mainly characterized by the non-activation of credit deterioration triggers. • Maximum contractual period: ITAÚ UNIBANCO HOLDING CONSOLIDATED estimates the useful life of assets that do not have fixed maturity date based on the period of exposure to credit risk and contractual terms, including prepayment and rollover options. • Prospective information: ITAÚ UNIBANCO HOLDING CONSOLIDATED uses macroeconomic forecasts and public information with projections prepared internally to determine the impact of these estimates on the calculation of expected credit loss. The main prospective information used to determine the expected credit loss is projected default, which is related to projections of Selic Rate, Credit Default Swap (CDS), unemployment rate, Gross Domestic Product (GDP), wages, industrial production and expanded retail sales. The definition of Macroeconomic scenarios involves inherent risks, market uncertainties and other factors that may give rise to results different from those expected. ITAÚ UNIBANCO HOLDING CONSOLIDATED uses weighted scenarios to determine credit loss expected over a suitable observation horizon adequate to classification in stages, which are reassessed annually or when the market conditions so require. 67 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 ITAÚ UNIBANCO HOLDING CONSOLIDATED uses the option to measure the expected credit loss based on the delayed payment of principal or interest, the loss history and other relevant information for financial instruments recognized in the heading Other Assets. IV.IV - Derivatives and use of hedge accounting These are classified on the date of their acquisition, according to whether or not management intends to use them for hedging, in conformity with BACEN Circular 3,082, of January 30, 2002. Transactions involving financial instruments, carried out at a customer’s request, for the bank’s own account, or which do not comply with the hedging criteria (mainly derivatives used to manage overall risk exposure), are stated at fair value, including realized and unrealized gains and losses, which are recorded directly in the Statement of Income. Derivatives that are used for protection against risk exposure or to modify the characteristics of financial assets and liabilities, where changes in fair value are closely related to those of the items being protected at the beginning and throughout the duration of the contract, and which are considered to be effective in reducing the risk exposure in question, are classified as hedges of the following types: • Cash flow hedge: the effective portion of a hedge of financial assets and liabilities, and the related financial instruments, are booked at fair value plus realized and unrealized gains and losses, net of tax effects, when applicable, and recorded in a specific account in Stockholders’ Equity. The ineffective portion is recorded directly in the Statement of Income. • Market fair value: financial assets and liabilities, as well as their related financial instruments, are booked at fair value, plus realized and unrealized gains and losses, which are recorded directly in the Statement of Income. • Hedge of net investments in foreign operations: accounted for similarly to a cash flow hedge: the effective portion of gains or losses of hedging instrument is recognized directly in Stockholders’ Equity and reclassified to income for the period in the event of the disposal of the foreign operation. The ineffective portion is recognized in income for the period. V - Other non-financial assets Other non-financial assets are composed of Prepaid expenses, Encrypted digital assets, Assets held for sale, among others. Encrypted digital assets can be used as a means of exchange or value reserve and are acquired for trading. Recognition and measurement are carried at fair value and are classified in level 1 of the fair value hierarchy, since their values reflect quoted (unadjusted) prices available in active markets. Subsequent appreciation and depreciation are recognized in income for the period. Assets Held for Sale are registered upon their receipt in the settlement of financial assets or by the decision to sell own assets. These assets are initially accounted for at the lower of: (i) the fair value of the good less the estimated selling costs (ii) their book value. ITAÚ UNIBANCO HOLDING CONSOLIDATED exercises judgment when assessing the fair value of the asset, either upon the initial recognition or in the subsequent measurement, considering, when applicable, evaluation reports and the likelihood of definitive hindrance to sale. VI - Investments in associates and joint ventures Associates are companies in which ITAÚ UNIBANCO HOLDING CONSOLIDATED has significant influence, mainly represented by participation in the Board of Directors or Executive Board, and in the processes of development of operating and financial policies, including the distribution of dividends, provided that they are not considered rights to protect minority interest. 68 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 Joint ventures are arrangements in which the parties are entitled to the net assets of the business, which is jointly controlled, this is, decisions about the business are made unanimously between the parties, regardless of their percentage of interest. Investments in associates and joint ventures include goodwill identified in the acquisition, net of any accumulated impairment loss. They are recognized at acquisition cost and are accounted for under the equity method. VII - Lease operations (Lessee) To conduct its commercial activities, ITAÚ UNIBANCO HOLDING CONSOLIDATED is the lessee, mainly of real estate (underlying assets) in the execution of the contract; future rent payments are recognized at present value discounted by an average funding rate (incremental rate) in the heading Other liabilities and the financial expense is recognized in income. In counterparty to this financial liability, a right of use is recognized in the headings of Fixed Assets and/or Intangible Assets, depreciated under the straight-line method for the lease term and tested semiannually to identify possible impairment losses. In case the underlying asset is of low value (except real estate), payments are recognized in liabilities as a counterparty to expense, when due. To establish the lease period, ITAÚ UNIBANCO HOLDING CONSOLIDATED considers the non-cancellable period of the contract, the expectation of renewal, contractual termination, and the expected vacancy period, as the case may be. The main judgments exercised in lease operations are: determination of the discount rate that reflects the cost that would be incurred to buy the asset; establishment of low-value assets; and assessment of the expectation of contractual renewal. VIII - Fixed assets Fixed assets are booked at their acquisition cost less accumulated depreciation, and adjusted for impairment, if applicable. Depreciation is calculated under the straight-line method using rates based on the estimated useful lives of these assets. ITAÚ UNIBANCO HOLDING CONSOLIDATED recognizes in fixed assets expenses that increase (i) productivity, (ii) efficiency or (iii) the useful life of the asset for more than one fiscal year. The main judgements are about the definition of the residual values and useful life of assets. IX - Goodwill and intangible assets Goodwill is generated in business combinations and acquisitions of ownership interests in associates and joint ventures. It represents the future economic benefits expected from the transaction that are neither individually identified nor separately recognized, being amortized based on the expected future profitability. Intangible assets are immaterial goods acquired or internally developed, they include the Association for the promotion and offer of financial products and services, software, rights of use leases and rights for acquisition of payrolls. Intangible assets are measured at amortized cost after initial recognition and amortized using the straight-line method over their estimated useful lives. X - Impairment of non-financial assets The recoverable amount of investments in associates and joint ventures, right-of-use assets, fixed assets, goodwill and intangible assets is assessed semiannually or when there is an indication of loss. The assessment is conducted individually by asset class whenever possible or by cash-generating unit (CGU). To assess the recoverable amount, ITAÚ UNIBANCO HOLDING CONSOLIDATED considers the materiality of the assets, except for goodwill, which is evaluated regardless of its amount. The main internal and external indications which can impact the recoverable amount are: business strategies established by management; obsolescence and/or disuse of software/hardware; and the macroeconomic, market and regulatory scenario. 69 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 Depending on the asset class, the recoverable amount is estimated using especially the methodologies: Discounted Cash Flow, Multiple and Dividend Flow, using a discount rate that in general reflects financial and economic variables, such as risk-free interest rate and a risk premium. The assessment of recoverable amount reflects Management’s best estimate for the expected future cash flows from individual assets or CGU, as the case may be. The main judgments exercised in the assessment of recoverable amount of non-financial assets are: the choice of the most appropriate methodology, the discount rate and assumptions for cash inflows and outflows. XI - Insurance, private pension and premium bonds operations Insurance contracts establish, for one of the parties, upon payment (premium) by the other party, the obligation to pay the latter a certain amount in the event of a claim. Insurance risk is defined as a future and uncertain event, of a sudden and unforeseeable nature, independent of the insured’s will, which may cause economic loss when it occurs. Once a contract is classified as an insurance contract, it remains as such until the end of its life, even if the insurance risk is significantly reduced during the period, unless all rights and obligations are extinguished or expired. Private pension plans refer to contracts that provide for retirement benefits after an accumulation period (known as PGBL, VGBL and FGB) provide a guarantee, at the commencement date of the contract, of the basis for calculating the retirement benefit (mortality table and minimum interest rates). The contracts specify the annuity rates and, therefore, the insurance risk is transferred to the issuer from the start. These contracts are classified as insurance contracts. Insurance premiums are accounted for over the term of the contracts in proportion to the amount of insurance coverage, through the establishment and reversal of a provision for unearned premiums and deferred selling expenses. Interest arising from fractioning of insurance premiums is accounted for as incurred. Revenues from pension contributions and the respective technical provisions are recognized upon receipt. The revenue arising from premium bonds quotas and raffles is recognized upon receipt, and the quota of carry after meeting the consideration. ITAÚ UNIBANCO HOLDING CONSOLIDATED recognizes, if there is any evidence of impairment losses with respect to receivables for insurance premiums, a sufficient provision to cover this loss, based on a risk analysis of realization of insurance premiums receivable with installments overdue. Reinsurance: in the ordinary course of business, ITAÚ UNIBANCO HOLDING CONSOLIDATED reinsures a portion of the risks underwritten, particularly property and casualty risks that exceed the maximum limits of responsibility that it determines to be appropriate for each segment and product (after a study which considers size, experience, special features, and the capital necessary to support these limits). These reinsurance agreements allow the recovery of a portion of losses from the reinsurer, although they do not release the insurer from the main obligation as direct insurer of the risks covered by the reinsurance. ITAÚ UNIBANCO HOLDING CONSOLIDATED exercises its judgment in assessing the recoverable amount of reinsurance receivables, based on its experience and reinsurers' rating. Technical provisions: are liabilities arising from obligations of ITAÚ UNIBANCO HOLDING CONSOLIDATED to its policyholders and participants. These obligations may be short term liabilities (property and casualty insurance) or medium and long term liabilities (life insurance and pension plans). The determination of the actuarial liability is subject to several uncertainties inherent in the coverage of insurance and pension contracts, such as assumptions of persistence, mortality, disability, life expectancy, morbidity, expenses, frequency and severity of claims, conversion of benefits into annuities, redemptions and return on assets. 70 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 The estimates for these assumptions are based on macroeconomic projections and the historical experience of ITAÚ UNIBANCO HOLDING CONSOLIDATED, benchmarks and the experience of the actuary, in order to comply with best market practices and constantly review of the actuarial liability. Liability adequacy test: ITAÚ UNIBANCO HOLDING CONSOLIDATED tests, semiannually, liability adequacy by adopting current actuarial assumptions for future cash flows of all insurance contracts and private pension plans in force on the test base date. Should the analysis show insufficiency, it will be accounted for in income for the period when arising from changes in the non-financial risk of insurance and in other comprehensive income, when arising from changes in the interest rate (ETTJ). XII - Provisions, contingent assets and contingent liabilities Provisions and contingent liabilities are assessed based on the Management’s best estimates considering the opinion of legal advisors. The accounting treatment of provisions and contingent liabilities depends on the likelihood of disbursing funds to settle obligations. According to the probability of loss they are classified as: (i) probable and are provisioned in the Financial Statements; (ii) possible, are not provisioned and are reported in the Notes; and (iii) remote: no provision is recognized, and contingent liabilities are not disclosed in the Financial Statements. Provisions and contingent liabilities are estimated in a mass or individualized basis: • Mass lawsuits: civil lawsuits and labor claims with similar characteristics, whose individual amounts are not relevant. The expected amount of the loss is estimated on a monthly basis, according to the statistical model. Civil and labor provision and contingencies are adjusted to the amount of the performance guarantee deposit when it is made. For civil lawsuits, their nature, and characteristics of the court in which they are being processed (Small claims court or ordinary court) is observed. For labor claims, the estimated amount is reassessed considering the court decisions rendered. • Individual lawsuits: civil lawsuits, labor claims, tax claims and social security lawsuits with peculiar characteristics or relevant amounts. For civil lawsuits and labor claims, the expected amount of the loss is periodically estimated, as the case may be, based on the determination of the amount claimed and the particularities of the lawsuits. The likelihood of loss is assessed according to the characteristics of facts and points of law regarding that lawsuit. Tax and social security lawsuits are assessed individually and are accounted for at the amount due. Assets pledged as guarantees of civil lawsuits, labor claims, tax claims and social security lawsuits should be conducted in court and are retained until a definitive court decision is made. Cash deposits, surety insurance, sureties and government securities are offered, and in case of unfavorable decision, the amount is paid to the counterparty. The amount of judicial deposits is updated in accordance with the regulations in force. Civil, labor, tax, and social security provisions, guaranteed by indemnity clauses in privatization and other procedures, in which there is liquidity, are recognized upon judicial notice, simultaneously with amounts receivable, not having effect on income. The main judgments exercised in the measurement of provisions and contingencies are: assessment of the probability of loss; aggregation of mass lawsuits; selection of the statistical model for loss assessment; and estimated provisions amount. Information on provisions and contingencies for legal proceedings are detailed in Note 11. XIII - Income tax and social contribution The provision for income tax and social contribution is composed for current taxes, which are recovered or paid during the reporting period, and deferred taxes, represented by deferred tax assets and liabilities, arising from the differences between the tax bases of assets and liabilities and the amounts reported at the end of each period. 71 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 Deferred tax assets may arise from: temporary differences, which may be deductible in future periods; and income tax losses and social contribution tax loss on net income, which may be offset in the future. The expected realization of deferred tax assets is estimated based on the projection of future taxable profits and other technical studies, observing the history of profitability for each subsidiary and for the consolidated taken as whole. The main assumptions considered in the projections of future taxable income are: macroeconomic variables, exchange rates, interest rates, volume of financial operations, service fees, internal business information, among others, which may present variations in relation to actual data and amounts. The main judgments that ITAÚ UNIBANCO HOLDING CONSOLIDATED exercises in recognition of deferred tax assets and liabilities are: identification of deductible and taxable temporary differences in future periods; and evaluation of the likelihood of the existence of future taxable profit against which the deferred tax assets may be used, considering the history of taxable income or income in at least three of the last five fiscal years. Tax rates, as well as their calculation bases, are detailed in Note 20. XIV - Post-employment benefits ITAÚ UNIBANCO HOLDING CONSOLIDATED sponsors post-employment benefit plans for employees in Defined Benefit, Defined Contribution and Variable Contribution modalities. The present value of obligations, net of fair value of assets, is recognized in the actuarial liabilities according to the characteristics of the plan and actuarial estimates. When the fair value of the plan assets exceeds the present value of obligations, an asset is recognized, limited to the rights of ITAÚ UNIBANCO HOLDING CONSOLIDATED. Actuarial estimates are based on assumptions of the following nature: (i) demographic: mainly the mortality table; and (ii) financial: the most relevant ones are the projection of inflation and the discount rate used to determine the present value of the obligations that considers the yields of government securities and the maturity of respective obligations. Annual remeasurements of the plans are recognized under Stockholders’ Equity, in Other Comprehensive Income. The main judgments exercised in calculating the obligation of post-employment benefit plans are: selection of the mortality table and the discount rate. XV - Commissions and banking fees Commissions and banking fees are recognized when ITAÚ UNIBANCO HOLDING CONSOLIDATED provides or offers services to customers, in an amount that reflects the consideration ITAÚ UNIBANCO HOLDING CONSOLIDATED expects to collect in exchange for those services. Incremental costs, when material, are recognized in assets and appropriated in income according to the expected term of the contract. Service revenues related to credit cards, debit, current account, payments and collections and economic, financial and brokerage advisory are recognized when said services are provided. Revenue from certain services, such as fees from funds management, collection and custody, are recognized over the life of the respective agreements, as services are provided. ITAÚ UNIBANCO HOLDING CONSOLIDATED exercises judgment to identify whether the performance obligation is satisfied over the life of the contract or at the time the service is provided. 72 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 Note 3 - Business development Zup I.T. Serviços em Tecnologia e Inovação S.A. On October 31, 2019, ITAÚ UNIBANCO HOLDING, through its subsidiary Redecard Instituição de Pagamento S.A.

Note 7 - Hedge accounting The accounting policy on Hedge accounting is presented in Note 2c IV. ITAÚ UNIBANCO HOLDING CONSOLIDATED has a risk limits structure applied to each risk factor, which aims at improving the monitoring and understanding of risks, in addition to avoiding their concentration. In hedge accounting, the groups of risk factors comprise: • Interest Rate: Risk of loss in transactions subject to interest rate variations. • Currency: Risk of loss in transactions subject to foreign exchange variation. The structures designated for the risk factor groups are carried out considering the risks in their totality when there are compatible hedge instruments. In certain cases, management may decide to hedge a risk for the risk factor term and limit of the hedging instrument. The other risk factors hedged by the institution are presented in Note 27. To protect cash flows and fair value of instruments designated as hedged items, derivatives and financial assets are used. 81 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 ITAÚ UNIBANCO HOLDING CONSOLIDATED manages risks through the economic relationship between hedging instruments and hedged items, where the expectation is that these instruments will move in opposite directions and in the same proportion, with the purpose of neutralizing risk factors. For portfolio strategies, the coverage ratio is often re-established as both the protected item and instruments change over time, reflecting risk management guidelines approved by management. The designated coverage ratio is always 100% of the risk factor eligible for coverage. Sources of ineffectiveness are in general related to the counterparty’s credit risk and possible mismatches of terms between the hedging instrument and the hedged item. a) Summaries by instrument and hedge item, nominal amount and maturity 09/30/2025 Hedge instruments Hedged item Notional amount Fair value adjustment Gross book value Cash flow hedge 177,757 (257) 177,824 Hedge of assets transactions 2,526 - 2,509 Hedge of asset-backed securities under repurchase agreements 12,077 - 12,444 Hedge of assets denominated in Chilean unit of account 55,492 (224) 55,492 Hedge of loan operations 20,209 26 20,209 Hedge of deposits and repurchase agreements 53,437 - 53,218 Hedge of funding 32,913 (61) 32,914 Hedge of highly probable forecast transactions 1,103 2 1,038 Hedge of net investment in foreign operations 26,351 (60) 25,666 Hedge of net investment in foreign operations 26,351 (60) 25,666 Fair value hedge 153,299 (1,232) 155,371 Hedge of securities at amortized cost 69,633 (1,119) 72,463 Hedge of securities at fair value through other comprehensive income 21,305 43 20,584 Hedge of loan operations 29,644 (132) 29,644 Hedge of funding 32,659 (24) 32,618 Hedge of firm commitments 58 - 62 Total 357,407 (1,549) 358,861 82 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 09/30/2025 0-1 year 1-2 years 2-3 years 3-4 years 4-5 years 5-10 years Over 10 years Total Cash flow hedge 102,573 31,574 16,326 8,580 12,879 5,825 - 177,757 Hedge of assets transactions - - 2,001 - 525 - - 2,526 Hedge of asset-backed securities under repurchase agreements - - 7,863 4,214 - - - 12,077 Hedge assets denominated in Chilean unit of account 52,303 3,189 - - - - - 55,492 Hedge of loan operations 9,509 3,900 727 1,106 4,967 - - 20,209 Hedge of deposits and repurchase agreements 25,394 14,567 3,081 2,747 1,972 5,676 - 53,437 Hedge of funding 14,265 9,917 2,654 513 5,415 149 - 32,913 Hedge of highly probable forecast transactions 1,102 1 - - - - - 1,103 Hedge of net investment in foreign operations 26,351 - - - - - - 26,351 Hedge of net investment in foreign operations (1) 26,351 - - - - - - 26,351 Fair value hedge 58,393 21,555 25,996 12,448 8,538 21,569 4,800 153,299 Hedge of securities at amortized cost 10,575 8,743 16,260 5,836 6,240 18,707 3,272 69,633 Hedge of securities at fair value through other comprehensive income 16,700 125 2,865 261 214 216 924 21,305 Hedge of loan operations 12,700 5,906 4,330 4,522 402 1,486 298 29,644 Hedge of funding 18,360 6,781 2,541 1,829 1,682 1,160 306 32,659 Hedge of firm commitments 58 - - - - - - 58 Total 187,317 53,129 42,322 21,028 21,417 27,394 4,800 357,407 1) Classified as current, since instruments are renewed often. b) Cash flow hedge Strategies are used to manage the variation: • In the cash flow of interest payment by using futures contracts: Hedge of asset transactions (DI); Hedge of asset repurchase agreements (Selic); Hedge of time deposits and repurchase agreements (DI). • In the cash flow of interest payment by using swap contracts: Hedge of assets denominated in Chilean unit of account (UF); Hedge of loan operations (Monetary policy rate - TPM); Hedge of funding (TPM). • In the amount of the commitments assumed, caused by variation in the exchange rates: Hedge of highly probable forecast transactions (foreign currency), not recognized in the balance sheet. 83 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 Strategies Heading 09/30/2025 Hedged item Hedge instrument Book value Variation in value recognized in other comprehensive income Cash flow hedge reserve Notional amount Variation in fair value used to calculate hedge Assets Liabilities ineffectiveness Interest rate risk Hedge of assets transactions Operations with credit granting characteristics 2,509 - 7 (9) 2,526 7 Hedge of asset-backed securities under repurchase agreements Securities purchased under agreements to resell 12,444 - (216) (1,167) 12,077 (216) Hedge of assets denominated in Chilean unit of account Securities 55,492 - (60) (70) 55,492 (60) Hedge of loan operations Loan and lease operations 20,209 - 31 89 20,209 31 Hedge of deposits and repurchase agreements Securities sold under repurchase agreements and Deposits - 53,218 (219) 220 53,437 (219) Hedge of funding Deposits - 31,364 (19) (45) 31,363 (19) Foreign exchange risk Hedge of funding Deposits - 1,550 (6) (6) 1,550 (6) Hedge of highly probable forecast transactions 51 987 75 168 1,103 75 Total 90,705 87,119 (407) (820) 177,757 (407) Hedges of asset transactions, asset-backed securities under repurchase agreements and deposits and repurchase agreements to resell are portfolio strategies.

In the ordinary course of its business, ITAÚ UNIBANCO HOLDING CONSOLIDATED may be a party to legal proceedings of labor, civil and tax nature. The contingencies related to these lawsuits are classified as follows: a) Contingent assets There are no contingent assets recorded. b) Provisions and contingencies ITAÚ UNIBANCO HOLDING CONSOLIDATED’s provisions for judicial and administrative challenges are long-term, considering the time required for their questioning, and this prevents the disclosure of a deadline for their conclusion. The legal advisors believe that ITAÚ UNIBANCO HOLDING CONSOLIDATED is not a party to this or any other administrative proceedings or lawsuits, in addition to those highlighted throughout this note, that could significantly affect the results of its operations. Civil lawsuits In general, provisions and contingencies arise from claims related to the revision of contracts and compensation for material and moral damages. ITAÚ UNIBANCO HOLDING CONSOLIDATED, despite having complied with the rules in force at the time, is a defendant in lawsuits filed by individuals referring to payment of inflation adjustments to savings accounts resulting from economic plans implemented in the 1980s and the 1990s, as well as in collective lawsuits filed by: (i) consumer protection associations; and (ii) the Public Attorney’s Office, on behalf of the savings accounts holders. In relation to these lawsuits, ITAÚ UNIBANCO HOLDING CONSOLIDATED recognizes provisions upon receipt of summons, and when individuals demand the enforcement of a ruling handed down by the courts, using the same criteria as for provisions for individual lawsuits. In December 2017, through mediation of the Federal Attorney’s Office (AGU) and supervision of the BACEN, savers (represented by two civil associations, FEBRAPO and IDEC) and FEBRABAN entered into an instrument of agreement aiming at resolving lawsuits related to the economic plans, and ITAÚ UNIBANCO HOLDING CONSOLIDATED has already accepted its terms. Said agreement was approved on March 1, 2018, by the Plenary Session of the Federal Supreme Court (STF) and savers could adhere to its terms for a 24-month period. Due to the end of this term, the parties signed an amendment to the instrument of agreement to extend this period in order to contemplate a higher number of holders of savings accounts and, consequently, to extend the end of lawsuits. In May, 2020, the Federal Supreme Court (STF) approved this amendment and granted a 30-month term for new adhesions, and subsequently extended for another 30 months, subject to the reporting of the number of adhesions over the first period. In May 2025, the Federal Supreme Court (STF) unanimously declared the constitutionality of the economic plans Bresser (1987), Verão (1989), Collor I (1990) and Collor II (1991) and reaffirmed the approval of the collective bargaining agreement. As a result of this decision, the deadline for adhesion was extended by another 24 months. 95 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 Labor claims Provisions and contingencies arise from lawsuits in which labor rights provided for in labor legislation specific to the related profession are discussed, such as: overtime, salary equalization, reinstatement, transfer allowance, and pension plan supplement, among others. Other risks These are quantified and accrued on the basis of the amount of rural credit transactions with co-obligation and FCVS (salary variations compensation fund) credits assigned.

Level 3: Securities and derivatives for which pricing inputs are generated by statistical and mathematical models. Debentures and other corporate securities that do not fit into level 2 rule and derivatives with maturities greater than the last observable vertices of the discount curves are at this level. 107 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 I - Fair value of financial assets and liabilities 09/30/2025 Level 1 Level 2 Level 3 Fair value Financial assets 433,740 361,558 402 795,700 Financial assets at fair value through other comprehensive income 152,011 4,828 237 157,076 Government securities 147,732 - - 147,732 Brazil 101,517 - - 101,517 Latin America 27,620 - - 27,620 Abroad 18,595 - - 18,595 Corporate securities 3,605 4,777 237 8,619 Bank deposit certificate - 151 - 151 Real estate receivable certificate - 18 - 18 Debentures 1,696 854 237 2,787 Eurobonds and other 1,909 3,434 - 5,343 Financial bills - 5 - 5 Promissory notes - 40 - 40 Other - 275 - 275 Shares 674 51 - 725 Financial assets at fair value through profit or loss 281,729 356,730 165 638,624 Government securities 273,192 3,682 - 276,874 Brazil 253,561 3,682 - 257,243 Latin America 19,003 - - 19,003 Abroad 628 - - 628 Corporate securities 2,772 7,735 51 10,558 Rural product note - 1,033 - 1,033 Real estate receivable certificate 92 306 - 398 Debentures 1,899 2,220 51 4,170 Eurobonds and other 602 2,529 - 3,131 Financial bills - 266 - 266 Promissory notes - 18 - 18 Other 179 1,363 - 1,542 Shares 5,013 16,022 114 21,149 Investment funds 752 6,010 - 6,762 Specially organized investment funds (PGBL/ VGBL) - 323,281 - 323,281 Other Financial Assets - 2,708 - 2,708 Non-financial assets 3,079 - - 3,079 108 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 The following table presents the breakdown of fair value hierarchy levels for derivative assets and liabilities. 09/30/2025 Level 1 Level 2 Level 3 Fair value Assets 213 80,364 213 80,790 Options - 19,188 10 19,198 Forward 211 12,605 17 12,833 Swaps - 39,185 186 39,371 NDF - 7,737 - 7,737 Credit derivatives - 635 - 635 Other 2 1,014 - 1,016 Liabilities (1,522) (75,002) (1,101) (77,625) Options (1) (16,169) (60) (16,230) Forward (1,476) (12,296) (15) (13,787) Swaps - (37,655) (1,026) (38,681) NDF - (8,295) - (8,295) Credit derivatives - (383) - (383) Other (45) (204) - (249) 109 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 II - Result of fair value adjustment of assets and liabilities 01/01 to 09/30/2025 Level 1 Level 2 Level 3 Adjustment to fair value Financial assets 7,623 308 (97) 7,834 Financial assets at fair value through other comprehensive income 1,302 134 (3) 1,433 Government securities 1,030 - - 1,030 Brazil 1,011 - - 1,011 Latin America (32) - - (32) Abroad 51 - - 51 Corporate securities (13) 129 (4) 112 Bank deposit certificates - (1) - (1) Debentures 33 40 (4) 69 Eurobonds and other (46) 90 - 44 Shares 285 5 1 291 Financial assets at fair value through profit or loss 6,321 174 (94) 6,401 Government securities 5,506 (72) - 5,434 Brazil 5,366 (72) - 5,294 Latin America 122 - - 122 Abroad 18 - - 18 Corporate securities 151 140 8 299 Rural product note - (30) - (30) Real estate receivables certificates 2 14 - 16 Debentures 125 94 8 227 Eurobonds and other 24 32 - 56 Financial bills - (3) - (3) Other - 33 - 33 Shares 626 (260) (102) 264 Investment funds 38 366 - 404 Derivative - assets 642 (23,192) (340) (22,890) Options - (125) (62) (187) Forward 648 (763) - (115) Swaps - (21,898) (276) (22,174) NDF - Non deliverable forward (1) (105) - (106) Credit derivatives - 164 (2) 162 Other (5) (465) - (470) Derivative - liabilities (85) 15,818 (1,375) 14,358 Options (1) (2,507) - (2,508) Forward (111) 2,993 (13) 2,869 Swaps - 14,420 (1,362) 13,058 NDF - Non deliverable forward 12 (149) - (137) Credit derivatives - 1,168 - 1,168 Other 15 (107) - (92) 110 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 Governance of Level 3 recurring fair value measurement The departments in charge of defining and applying the pricing models are segregated from the business areas. The models are documented, submitted to validation by an independent area and approved by a specific committee. The daily processes of price capture, calculation and disclosure are periodically checked according to formally defined tests and criteria and the information is stored in a single corporate database. The most frequent cases of assets classified as Level 3 are justified by the discount factors used and corporate bonds whose credit component is relevant. Factors such as the fixed interest curve in Brazilian Reais and the TR coupon curve – and, as a result, their related factors – have inputs with terms shorter than the maturities of fixedincome assets. Changes in the fair value hierarchy In the periods, there were no material transfer between Level 1 and Level 2. The tables below show balance sheet changes for financial instruments classified by ITAÚ UNIBANCO HOLDING CONSOLIDATED in Level 3 of the fair value hierarchy. Derivatives classified in Level 3 correspond to swaps and options.

Material unobservable inputs used for measurement of the fair value of instruments classified in Level 3 are: interest rates, underlying asset prices and volatility. Material variations in any of these inputs separately may give rise to material changes in the fair value. The table below shows the sensitivity of these fair values in scenarios of changes of interest rates, in asset prices and in scenarios with varying shocks to prices and volatilities for nonlinear assets, considering: Interest rate: Shocks of 1, 25 and 50 basis points (scenarios I, II and III respectively) applied to the interest curves, both up and down, taking the largest losses resulting in each scenario. Commodities, index and shares: Shocks of 5 and 10 percentage points (scenarios I and II respectively) applied to asset prices, both up and down, taking the largest losses resulting in each scenario. Nonlinear: Scenario I: Shocks of 5 percentage points applied on prices and 25 percentage points on the volatility level, both up and down, taking the largest losses resulting in each scenario. Scenario II: Shocks of 10 percentage points applied on prices and 25 percentage points on the volatility level, both up and down, taking the largest losses resulting in each scenario.

The methods used to estimate the fair value of financial instruments not measured at fair value are: • Interbank investments - The book value of Securities purchased under agreements to resell is close to their fair value and the fair value of Interbank deposits is calculated by discounting estimated cash flows at market interest rates. • Securities - Under normal conditions, the prices quoted in the market are the best indicators of the fair values of these financial instruments. However, not all instruments have liquidity or quoted market prices and, in 112 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 such cases, are priced by conventional or internal models, with inputs captured directly, built based on observations of active markets, or generated by statistical and mathematical models. • Operations with credit granting characteristics - Fair value of loan operations is estimated for groups of loans with similar financial and risk characteristics, using valuation models. The fair value of fixed-rate loans is determined by discounting estimated cash flows, at interest rates applicable to similar loans. For the majority of loans at floating rates, the book value is considered to be close to their fair value. The fair value of loan and lease operations not overdue is calculated by discounting the expected payments of principal and interest to maturity. The fair value of overdue loan and lease operations is based on the discount of estimated cash flows, using a rate proportional to the risk associated with the estimated cash flows, or on the underlying collateral. The assumptions for cash flows and discount rates rely on information available in the market and specific knowledge of the debtor. For the securities with credit granting characteristics, under normal conditions, quoted market prices are used, and for those that do not have liquidity or quotation, they are priced by conventional or internal models. • Deposits, debit instruments and borrowing and onlending - They are calculated by discounting estimated cash flows at market interest rates. • Securities sold under repurchase agreements - The book value for these instruments is close to their fair values. • Other financial assets / liabilities - Primarily composed for receivables from credit card issuers, deposits in guarantee for contingent liabilities, provisions and legal obligations and trading and intermediation of securities. The book value for these assets/liabilities substantially approximate to their fair values, since they principally represent amounts to be received in the short term from credit card holders and to be paid to credit card issuers, deposits demanded judicially (indexed to market rates) made by ITAÚ UNIBANCO HOLDING to secure lawsuits or very short-term receivables (generally with a maturity of approximately 5 business days). All of these items represent assets/liabilities without material market, credit or liquidity risks. Note 18 - Stockholders' equity a) Capital In a meeting held on February 5, 2025, the Board of Directors approved the increase in the subscribed and paid up capital in the amount of R$ 33,334, through capitalization of amounts recorded in Profit Reserves - Statutory Reserve, with a 10% bonus in shares. The bonus shares were issued and started to be traded as from March 20, 2025. Consequently, capital was increased by 980,413,535 shares. Capital is represented by 10,784,548,883 book-entry shares with no par value, of which 5,454,119,395 are common shares and 5,330,429,488 are preferred shares with no voting rights, but with tag-along rights in a public offering of shares, in a possible transfer of control, assuring them a price equal to eighty per cent (80%) of the amount paid per voting share in the controlling block, and a dividend at least equal to that of the common shares. The breakdown and change in shares of paid-in capital in the beginning and end of the period are shown below: 113 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 01/01/2025 09/30/2025 01/01/2025 Number Amount Common Preferred Total Residents in Brazil 01/01/2025 4,918,480,340 1,325,492,746 6,243,973,086 57,783 Residents abroad 01/01/2025 39,810,019 3,520,352,243 3,560,162,262 32,946 Shares of capital stock 01/01/2025 4,958,290,359 4,845,844,989 9,804,135,348 90,729 Bonus shares – Outstanding as from 03/20/2025 495,829,036 484,584,499 980,413,535 Shares of capital stock 09/30/2025 5,454,119,395 5,330,429,488 10,784,548,883 124,063 Residents in Brazil 09/30/2025 5,409,573,404 1,298,378,805 6,707,952,209 77,167 Residents abroad 09/30/2025 44,545,991 4,032,050,683 4,076,596,674 46,896 Treasury shares (1) 01/01/2025 - 28,030,833 28,030,833 (909) Acquisition of treasury shares - 50,656,881 50,656,881 (1,894) Result of delivery of treasure shares - (30,230,512) (30,230,512) 981 Bonus shares – Treasury as from 03/20/2025 - 86,718 86,718 Treasury shares (1) 09/30/2025 - 48,543,920 48,543,920 (1,822) Number of total shares at the end of the period (2) 09/30/2025 5,454,119,395 5,281,885,568 10,736,004,963 1) Own shares purchased based on authorization of the Board of Directors to be held in Treasury for subsequent cancellation or replacement in the market. 2) Shares representing total capital stock net of treasury shares.

The grant of these benefits is only made in years in which there are sufficient profits to permit the distribution of mandatory dividends, limiting dilution to 0.5% of the total shares held by the controlling and minority stockholders at the balance sheet date. These programs are settled through the delivery of ITUB4 treasury shares to stockholders. Expenses on share-based payment plans are presented in the table below: 01/01 to 09/30/2025 Partner plan (371) Share-based plan (448) Total (819) I - Partner plan The program enables employees and managers of ITAÚ UNIBANCO HOLDING to invest a percentage of their bonus to acquire shares and share-based instruments. There is a lockup period of from three to five years, counted from the initial investment date, and the shares are thus subject to market price variations. After complying with the preconditions outlined in the program, beneficiaries are entitled to receive shares as consideration, in accordance with the number of shares indicated in the program internal regulations. The acquisition price of shares and share-based instruments is established every six months as the average of the share price over the last 30 days, which is performed on the seventh business day prior to the compensation grant date. The fair value of the consideration in shares is the market price at the grant date, less expected dividends.

Shares are delivered on a deferred basis, of which one-third per year, upon compliance with the conditions provided for in internal regulation. The deferred unpaid portions may be reversed proportionally to a significant reduction in the recurring income realized or the negative income for the period. Management members become eligible for the receipt of these benefits according to individual performance, business performance or both. The benefit amount is established according to the activities of each management member who meets at least the performance and conduct requirements. The fair value of the share is the market price at its grant date, less expected dividends.

Retirement plans are managed by Closed-end Private Pension Entities (EFPC) and are closed to new adhesions. These entities have an independent structure and manage their plans according to the characteristics of their regulations. There are three types of retirement plans: • Defined benefit plans (BD): plans for which scheduled benefits have their value established in advance, based on salaries and/or length of service of employees, and the cost is actuarially determined. The plans classified in this category are: Plano de Aposentadoria Complementar; Plano de Aposentadoria Complementar Móvel Vitalícia; Plano de Benefício Franprev; Plano de Benefício 002; Plano de Benefícios Prebeg; Plano BD UBB PREV; Plano de Benefícios II; Plano Básico Itaulam; Plano BD Itaucard; Plano de Aposentadoria Principal Itaú Unibanco managed by Fundação Itaú Unibanco - Previdência Complementar (FIU); and Plano de Benefícios I, managed by Fundo de Pensão Multipatrocinado (FUNBEP). • Defined contribution plans (CD): plans for which scheduled benefits have their value permanently adjusted to the investments balance, kept in favor of the participant, including in the benefit concession phase, considering net proceedings of its investment, amounts contributed and benefits paid. Defined Contribution plans include pension funds consisting of the portions of sponsor's contributions not included in a participant's account balance due to loss of eligibility for the benefit, and of monies arising from the migration of retirement plans in defined benefit modality. These funds are used for future contributions to individual participant's accounts, according to the respective benefit plan regulations. The plans classified in this category are: Plano Itaubanco CD; Plano de Aposentadoria Itaubank; Plano de Previdência REDECARD managed by FIU. • Variable contribution plans (CV): in this type of plan, scheduled benefits present a combination of characteristics of defined contribution and defined benefit modalities, and the benefit is actuarially determined based on the investments balance accumulated by the participant on the retirement date. The plans classified in this category are: Plano de Previdência Unibanco Futuro Inteligente; Plano Suplementar Itaulam; Plano CV Itaucard; Plano de Aposentadoria Suplementar Itaú Unibanco managed by FIU and Plano de Benefícios II managed by FUNBEP. a) Main actuarial assumptions The table below shows the actuarial assumptions of demographic and financial nature used to calculate the defined benefit obligation: Type Assumption 09/30/2025 Demographic Mortality table AT-2000 softned by 10% Financial Discount rate (1) 11.59% p.a. Financial Inflation (2) 4.00% p.a. 1) Considers the interest rates of the National Treasury Notes (NTN-B) with maturity dates near the terms of the respective obligations, compatible with the economic scenario observed on the balance sheet closing date, considering the volatility of interest market and models used. 2) Long-term inflation projected by the market, according to the maturity of each plan. Retirement plans sponsored by foreign subsidiaries - Banco Itaú (Suisse) S.A., Itaú Colombia S.A. and PROSERV - Promociones y Servicios S.A. de C.V. - are structured as Defined Benefit modality and adopt actuarial assumptions adequate to masses of participants and the economic scenario of each country. b) Risk management The EFPCs sponsored by ITAÚ UNIBANCO HOLDING are regulated by the National Council for Complementary Pension (CNPC) and PREVIC, and have an Executive Board, Advisory and Tax Councils. 125 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 Benefits offered have long-term characteristics and the main factors involved in the management and measurement of their risks are financial risk, inflation risk and demographic risk. • Financial risk - the actuarial liability of the plan is calculated by adopting a discount rate, which may differ from rates earned in investments. If real income from plan investments is lower than yield expected, this may give rise to a deficit. To mitigate this risk and assure the capacity to pay long-term benefits, the plans have a significant percentage of fixed-income securities pegged to the plan commitments, aiming at minimizing volatility and risk of mismatch between assets and liabilities. Additionally, adherence tests are carried out in financial assumptions to ensure their adequacy to obligations of respective plans. • Inflation risk - a large part of liabilities is pegged to inflation risk, making actuarial liabilities sensitive to increases in rates. To mitigate this risk, the same financial risks mitigation strategies are used. • Demographic risk - plans that have any obligation actuarially assessed are exposed to demographic risk. In the event the mortality tables used do not reflect actual conditions of the mass of plan participants, a deficit or surplus may arise in actuarial evaluation. To mitigate this risk, adherence tests to demographic assumptions are conducted to ensure their adequacy to liabilities of respective plans. For purposes of registering in the balance sheet of the EFPCs that manage them, actuarial liabilities of plans apply a discount rate adherent to their asset portfolio and income and expense flows, according to a study prepared by an independent actuarial consulting company. The actuarial method used is the aggregate method, through which the plan costing is defined by the difference between its equity coverage and the current value of its future liabilities, observing the methodology established in the respective actuarial technical note. When a deficit in the concession period above the legally defined limits is noted, debt agreements are entered into with the sponsor according to costing policies, which affect the future contributions of the plan, and a plan for solving such deficit is established respecting the guarantees set forth by the legislation in force. The plans that are in this situation are resolved through extraordinary contributions that affect the values of the future contribution of the plan. 126 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 c) Asset management The purpose of the management of funds is the long-term balance between pension assets and liabilities with payment of benefits by exceeding actuarial goals (discount rate plus benefit adjustment index, established in the plan regulations). Below is a table with the allocation of assets by category, segmented into Quoted in an active market and Not quoted in an active market: Types Fair value % Allocation 09/30/2025 09/30/2025 Fixed income securities 21,277 96.4% Quoted in an active market 20,627 93.5% Non quoted in an active market 650 2.9% Variable income securities 1 - Quoted in an active market 1 - Structured investments 129 0.6% Non quoted in an active market 129 0.6% Real estate 578 2.6% Loans to participants 88 0.4% Total 22,073 100.0% The defined benefit plan assets include shares of ITAÚ UNIBANCO HOLDING, its main parent company (ITAÚSA) and of subsidiaries of the latter, with a fair value of R$ 1, and real estate rented to group companies, with a fair value of R$ 511. d) Other post-employment benefits ITAÚ UNIBANCO HOLDING CONSOLIDATED does not have additional liabilities related to post-employment benefits, except in cases arising from maintenance commitments assumed in acquisition agreements which occurred over the years, as well as those benefits originated from court decision in the terms and conditions established, in which there is total or partial sponsorship of health care plans for a specific group of former employees and their beneficiaries. Its costing is actuarially determined so as to ensure coverage maintenance. These plans are closed to new applicants. Assumptions for discount rate, inflation, mortality table and actuarial method are the same as those used for retirement plans. ITAÚ UNIBANCO HOLDING CONSOLIDATED used the percentage of 4% p.a. for medical inflation, additionally considering, inflation rate of 4% p.a. Particularly in other post-employment benefits, there is medical inflation risk associated with above expectation increases in medical costs. To mitigate this risk, the same financial risk mitigation strategies are used. 127 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 e) Change in the net amount recognized in the balance sheet The net amount recognized in the Balance Sheet is limited by the asset ceiling and it is computed based on estimated future contributions to be realized by the sponsor, so that it represents the maximum reduction amount in the contributions to be made. 09/30/2025 BD and CV plans CD plans Other postemployment benefits Total Note Net assets Actuarial liabilities Asset ceiling Recognized amount Pension plan fund Asset ceiling Recognized amount Liabilities Recognized amount Amounts at the beginning of the period 21,490 (19,035) (4,237) (1,782) 365 (81) 284 (562) (2,060) Amounts recognized in income (1+2+3+4) 1,788 (1,583) (364) (159) (9) (7) (16) (46) (221) 1 - Cost of current service - (18) - (18) - - - - (18) 2 - Cost of past service - - - - - - - - - 3 - Net interest 1,788 (1,565) (364) (141) 37 (7) 30 (46) (157) 4 - Other revenues and expenses (1) - - - - (46) - (46) - (46) Amounts recognized in stockholders´ equity - other comprehensive income (5+6+7) (4) 27 (30) (7) - - - - (7) 5 - Effects on asset ceiling - - (30) (30) - - - - (30) 6 - Remeasurements - 15 - 15 - - - - 15 Changes in demographic assumptions - - - - - - - - - Changes in financial assumptions - - - - - - - - - Experience of the plan (2) - 15 - 15 - - - - 15 7 - Exchange variation (4) 12 - 8 - - - - 8 Other (8+9+10) (1,201) 1,413 - 212 - - - 62 274 8 - Receipt by Destination of Resources - - - - - - - - - 9 - Benefits paid (1,413) 1,413 - - - - - 62 62 10 - Contributions and investments from sponsor 212 - - 212 - - - - 212 Amounts at end of the period 22,073 (19,178) (4,631) (1,736) 356 (88) 268 (546) (2,014) Amount recognized in Assets 9a 18 268 - 286 Amount recognized in Liabilities 9b (1,754) - (546) (2,300) 1) It basically corresponds to the use of asset amounts allocated in pension funds of the defined contribution plans. 2) Correspond to the income obtained above/below the expected return and comprise the contributions made by participants. Net interest corresponds to the amount calculated on 01/01/2025 based on the initial amount (Net assets, Actuarial liabilities and Restriction of assets), deducting the estimated amount of payments/receipts of benefits/contributions, multiplied by the discount rate of 11.59% p.a.

The sensitivity analysis considers a vision of the impacts caused by changes in assumptions, which could affect the income for the period and stockholders’ equity at the balance sheet date. This type of analysis is usually carried out under the ceteris paribus condition, in which the sensitivity of a system is measured when only one variable of interest is changed and all the others remain unchanged. The results obtained are shown in the table below: Main assumptions BD and CV plans Other post-employment benefits Present value of liability Income Stockholders´ equity (Other comprehensive income) (1) Present value of liability Income Stockholders´ equity (Other comprehensive income) (1) Discount rate Increase by 0.5 p.p.

For this reason, the institution must have clearly established risk management objectives. In this context, the risk appetite articulates the set of guidelines of the Board of Directors on strategy and risk taking, defining the nature and level of risks acceptable for the institution, while the risk culture guides the attitudes required to manage them. ITAÚ UNIBANCO HOLDING CONSOLIDATED invests in robust risk management processes and capital management that permeate the whole institution and that are the basis for its strategic decisions to ensure business sustainability and maximize value creation for shareholders. Foremost among processes for proper risk and capital management are the implementation of a continuous and integrated risk management structure, of the Risk Appetite framework, which is composed of the Risk Appetite Statement (RAS) of the Board of Directors, risk appetite policy and the set of metrics for monitoring the main risks according to the limits established, the stress test program, the organization of a Risk Committee and the 131 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 appointment, before BACEN, of the Chief Risk Officer (CRO), with assignment of roles, responsibilities, and independence requirements. These processes are aligned with the guidelines of the Board of Directors and Executive which, through collegiate bodies, define the global objectives expressed as targets and limits for the business units that manage risk. Control and capital management units, in turn, support ITAÚ UNIBANCO HOLDING CONSOLIDATED’s management by monitoring and analyzing risk and capital. The principles that determine the risk management and the risk appetite foundations, as well as guidelines regarding the actions taken by ITAÚ UNIBANCO HOLDING CONSOLIDATED’s employees in their daily routines are as follows: • Sustainability and customer satisfaction: the vision of ITAÚ UNIBANCO HOLDING CONSOLIDATED is to be a leading bank in sustainable performance and customer satisfaction. For this reason the institution is concerned about creating shared values for employees, customers, shareholders and society to ensure the longevity of the business. ITAÚ UNIBANCO HOLDING CONSOLIDATED is concerned about doing business that is good for customers and for the institution. • Risk culture: the institution's risk culture goes beyond policies, procedures and processes. It strengths the individual and collective responsibility of all employees so that they will do the right thing at the right time and in the proper manner, respecting the ethical way of doing business. It is based on four principles (conscious risk taking, discussions and actions on the institution’s risks and everyone's responsibility for risk management), which encourage understanding and open discussion about risks, so that they are kept within the risk appetite levels established and so that each employee individually, regardless of their position, area or duties, may also assume responsibility for managing the risks of the business. • Risk pricing: ITAÚ UNIBANCO HOLDING CONSOLIDATED operates and assumes risks in business that its known and understood, avoiding risks about which there is no knowledge or do not provide competitive advantages, and carefully assesses risk-return ratios. • Diversification: the institution has a low appetite for volatility in its results, for this reason, accordingly it operates with a diversified base of customers, products and business, seeking the differentiation of risks, in addition to prioritizing less risky businesses. • Operational excellence: ITAÚ UNIBANCO HOLDING CONSOLIDATED intends to provide agility, as well as a robust and stable infrastructure, to offer high quality services. • Ethics and respect for regulations: at ITAÚ UNIBANCO HOLDING CONSOLIDATED, ethics is nonnegotiable. For this reason the institution promotes an institutional environment of integrity, educating all employees to cultivate ethical relationships and businesses and as well as respecting the norms, and therefore looking after the institution’s reputation. The Board of Directors is the maximum body responsible for establishing guidelines, policies and approval levels for risk and capital management. The Capital and Risk Management Committee (CGRC), in turn, is responsible for supporting the Board of Directors in managing capital and risk. At the executive level, collegiate bodies, chaired by the Chief Executive Officer (CEO) of ITAÚ UNIBANCO HOLDING CONSOLIDATED, who are responsible for risks and capital management performing delegated duties on these topics and their decisions are monitored by the CGRC. To support this structure, the Risk Department has specialized officers to ensure, on an independent and centralized basis, that the institution’s risks and capital are managed in compliance with the established policies and procedures. ITAÚ UNIBANCO HOLDING CONSOLIDATED’s risk management organizational structure complies with Brazilian and international regulations in place. Locally, the Bank follows the standards established by the Central Bank of Brazil (Bacen), particularly Resolution 4,557/17, which sets forth the risk and capital management structure of financial institutions, by the Securities and Exchange Commission (CVM) and by the Superintendence of Private 132 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 Insurance (SUSEP), among other regulators and applicable standards. At the international level, ITAÚ UNIBANCO HOLDING CONSOLIDATED follows the standards established by the Basel Committee for Banking Supervision, the Securities and Exchange Commission (SEC) of the United States and the local regulations of the countries where it is present. In addition,ITAÚ UNIBANCO HOLDING CONSOLIDATED adheres to guidelines such as the Foreign Account Tax Compliance Act (FATCA), the Principles for Responsible Banking (PRB) of the United Nations Environment Programme - Finance Initiative and the Guidelines for Multinational Companies of the Organization for Economic Cooperation and Development (OECD), pointing out some representative examples. The Bank also adopts practices in line with International Financial Reporting Standards (IFRS) and best corporate governance practices that are globally recognized. Additionally, ITAÚ UNIBANCO HOLDING CONSOLIDATED also has governance to identify and monitor emerging risks, which are those newly identified with medium and long term impact, potentially material on business, but for which there are not sufficient elements yet for their full assessment, due to the number of factors and impacts not fully known yet, since they have no precedents and therefore have never been addressed in the past. Responsibilities for risk management at ITAÚ UNIBANCO HOLDING CONSOLIDATED are structured according to the concept of three lines of governance, namely: • 1st line of governance: business areas and corporate support areas are directly responsible for identifying, measuring, assessing, monitoring, reporting, controlling, and mitigating the risks arising therefrom. • 2nd line of governance: risk area aims at ensuring, independently and centrally, that the institution’s risks are managed in compliance with policies and procedures established, setting parameters for the risk management process and its supervision. Such control provides the Board of Directors and executives with a global overview of ITAÚ UNIBANCO HOLDING CONSOLIDATED’s exposure, to ensure correct and timely corporate decisions. • 3rd line of governance: internal audit, which is linked to the Board of Directors and provides an independent assessment of the institution’s activities, so that senior management can see that controls are adequate, risk management is effective and institutional standards and regulatory requirements are being complied with. ITAÚ UNIBANCO HOLDING CONSOLIDATED uses robust automated systems for compliance with capital regulations, as well as for measuring risks in accordance with the regulatory determinations and models in place. It also monitors adherence to the qualitative and quantitative regulators’ minimum capital and risk management requirements. Aiming at strengthening its values and aligning the behavior of its employees with risk management guidelines, ITAÚ UNIBANCO HOLDING CONSOLIDATED adopts several initiatives to disseminate and strengthen a risk culture based on four principles: conscious risk taking, discussions and actions on the institution’s risks and everyone's responsibility for risk management. These principles serve as a basis for ITAÚ UNIBANCO HOLDING CONSOLIDATED guidelines, helping employees to conscientiously understand, identify, measure, manage and mitigate risks. Other information on Risk and Capital Management can be viewed at www.itau.com.br/relacoes-cominvestidores/ en/, in the section Results and reports, Regulatory reports, Pillar 3. b) Risk management Risk appetite Risk appetite articulates the Board of Directors' set of guidelines about strategy and risk taking, defining the nature and level of risks acceptable to the organization, and considering management capacity on an effective and prudent way, the strategic objectives, the conditions of competitiveness and the regulatory environment. 133 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 The Risk Appetite framework is composed of the Risk Appetite Statement (RAS) by the Board of Directors, the Risk Appetite policy, and the set of metrics for monitoring the main risks according to the limits established. Considering the strategic guidelines of ITAÚ UNIBANCO HOLDING CONSOLIDATED, the Risk Appetite and its dimensions are based on the following Statement: “We are a universal bank, operating predominantly in Latin America. Supported by our risk culture, we operate based on rigorous ethical and regulatory compliance standards, seeking high and growing results, with low volatility, by means of the long-lasting relationship with clients, correctly pricing risks, well-distributed fund-raising and proper use of capital.” To make RAS tangible, Risk Appetite was segmented in six dimensions, each of which comprising a set of metrics associated with the key risks involved, combining complementary measurements, to get a comprehensive view of our exposures on acceptable risk types and levels: • Capitalization: reflects the Bank’s level of protection against significant losses that could lead to regulatory non-compliance or insolvency. Establishes that ITAÚ UNIBANCO HOLDING CONSOLIDATED should have sufficient capital to protect itself against a serious recession or stress events without the need to adjust its capital structure under adverse circumstances. It is monitored through following up the ITAÚ UNIBANCO HOLDING CONSOLIDATED’s capital ratios, in usual or stress situations, and the institution’s debt issue ratings. • Liquidity: reflects the Bank’s level of protection against a long period of funding stress that could lead to illiquidity and possible bankruptcy. Establishes that the ITAÚ UNIBANCO HOLDING CONSOLIDATED’s liquidity should be able to support long stress periods. It is monitored by following up on liquidity ratios. • Composition of results: the purpose is to ensure the stability and sustainability of results, restricting excessive volatility and avoiding portfolio concentrations and significant deviations in pricing and provisions. Establishes that business will mainly focus on Latin America, where ITAÚ UNIBANCO HOLDING CONSOLIDATED will have a diversified range of customers and products, with low appetite for results volatility and high risk. To do so, it monitors Credit risk indicators, including social, environmental and climate dimensions, Market, and Interest Rate Risk in the Banking Book (IRRBB), Underwriting and Business & Profitability. The metrics monitored by the bank seek to ensure, by means of exposure concentration limits such as, for example, industry sectors, quality of counterparties, countries and geographic regions and risk factors, a suitable composition of the bank’s portfolios, aiming at low volatility of results and business sustainability. • Operational risk: addresses operating risks that may jeopardize the Bank’s business and operation, focusing on controlling events that may negatively impact the business strategy and operation. • Reputation: deals with risks that may impact brand value and the institution’s reputation before its customers, employees, regulators, investors and the general public. In this dimension, risks are monitored through ethical behavior and conservative compliance with regulatory standards. • Customer: addresses risks that may compromise customer satisfaction and experience, and is monitored by tracking customer satisfaction, direct impacts on customers, and suitability indicators. The metrics translate the RAS and dimensions into monitorable indicators, which capture the main risks incurred by the institution. They are periodically monitored and reported to the executive level, the Risk and Capital Management Committee and the Board of Directors, which guides the taking of preventive measures to ensure that exposures are within limits established and aligned with our strategy. The Board of Directors is responsible for the establishment and approval risk appetite guidelines and limits, performing its activities with the support of the CGRC and the Chief Risk Officer (CRO). The governance of Risk Appetite is registered in internal policy, established, reviewed, and also approved by the Board of Directors. 134 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 I - Credit risk The possibility of losses arising from failure by a borrower, issuer or counterparty to meet their financial obligations, the impairment of a loan due to downgrading of the risk rating of the borrower, the issuer or the counterparty, a decrease in earnings or remuneration, advantages conceded on renegotiation or the costs of recovery. There is a credit risk control and management structure, centralized and independent from the business units, that provides for operating limits and risk mitigation mechanisms, and also establishes processes and tools to measure, monitor and control the credit risk inherent in all products, portfolio concentrations and impacts of potential changes in the economic environment. The credit policy of ITAÚ UNIBANCO HOLDING CONSOLIDATED is based on internal criteria such as: classification of customers, portfolio performance and changes, default levels, rate of return and economic capital allocated, among others, and also considers external factors such as interest rates, market default indicators, inflation, changes in consumption, among other. With respect to individuals, small and medium-size companies, retail public, the credit ratings are assigned based on statistical application models (in the early stages of relationship with a customer) and behavior score (used for customers with whom ITAÚ UNIBANCO HOLDING CONSOLIDATED already has a relationship). For wholesale public and agribusiness, the classification is based on information such as the counterparty’s economic and financial situation, its cash-generating capacity, and the business group to which it belongs, the current and prospective situation of the economic sector in which it operates, in accordance with the guidelines of the Sustainability and Social and Environmental Responsibility Policy (PRSA) and specific manuals and procedures of ITAÚ UNIBANCO HOLDING CONSOLIDATED. Credit proposals are analyzed on a case-by-case basis through an authority level mechanism. In compliance with CMN Resolution 4,557, of February 23, 2017, the document “Public Access Report - Credit Risk Management and Control Policy”, which includes the guidelines established by our credit risk control policy, can be viewed at www.itau.com.br/relacoes-com-investidores/en, in the section Itaú Unibanco, under Corporate governance, Policies, Reports. I.I - Collateral and policies for mitigating credit risk ITAÚ UNIBANCO HOLDING CONSOLIDATED uses guarantees to increase its capacity for recovery in operations exposed to credit risk. The guarantees may be personal, secured, legal structures with mitigating power and offset agreements. Managerially, for collateral to be considered instruments that mitigate credit risk, it must comply with the requirements and standards that regulate such instruments, both internal and external ones, and they must be legally valid (effective), enforceable, and assessed on a regular basis. ITAÚ UNIBANCO HOLDING CONSOLIDATED also uses credit derivatives, such as single-name CDS, to mitigate credit risk of its securities portfolios. These instruments are priced based on models that use the fair value of market inputs, such as credit spreads, recovery rates, correlations and interest rates. I.II - Governance and measurement of expected credit loss Both the credit risk and the finance areas are responsible for defining the methods used to measure expected credit loss and for periodically assessing changes in the provision amounts. These areas monitor the trends observed in provisions for expected credit loss by business, in addition to establishing an initial understanding of the variables that may trigger changes in the allowance for loan losses, the probability of default (PD) or the loss given default (LGD), in which default is the moment when the contract becomes a problem asset. 135 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 ITAÚ UNIBANCO HOLDING CONSOLIDATED calculates the expected credit loss for Retail and Wholesale portfolios by multiplying PD, LGD and EAD (Exposure at Default), considering the prospective macroeconomic information in PD and LGD. I.III - Classification of credit impairment stages The accounting policy on expected credit loss is presented in Note 2c IV. ITAÚ UNIBANCO HOLDING CONSOLIDATED uses customers’ internal information, statistic models, days of default and quantitative analysis in order to determine the credit risk of the financial assets. The rules of stage change consider for the Retail and Wholesale segments: • Stage 1 to stage 2: delay or assessment of probability of default (PD) triggers. ITAÚ UNIBANCO HOLDING CONSOLIDATED migrates contracts overdue for over 30 days to stage 2, except real estate loans (overdue for 60 days), due to the operation risk. Regardless of the delay, migration to stage 2 occurs if the PD of the operation or the rating of the economic subgroup, as established for Retail and Wholesale, respectively, exceed the risk appetite approved by the Management of ITAÚ UNIBANCO HOLDING CONSOLIDATED. • Stage 3: indications are considered that the client will not honor the contracted conditions (problem asset), and the main ones are: 90 days overdue in the payment of principal and charges, debt restructuring, judicial measures, among others. The financial instrument, at any stage, may migrate to stage 3 when presenting indications of problem assets. For models that are not massified, in the event a financial instrument is allocated in stage 3, all financial instruments of the same economic subgroup/of the same counterparty are classified to stage 3, except for those whose nature and purpose do not indicate that the client will not honor the contracted conditions. Based on the classifications in stages, the measurement rules determined for expected credit loss are used, as described in Note 2c IV. 136 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 I.IV - Maximum exposure of financial assets to credit risk 09/30/2025 Financial assets 2,497,366 Interbank investments 334,802 Securities purchased under agreements to resell 264,696 Interbank deposits 65,278 Assets guaranteeing technical provisions 4,862 (Provision for expected credit loss) (34) Securities 922,587 Own portfolio 270,288 Restricted 309,891 Assets guaranteeing technical provisions 343,285 (Provision for expected credit loss) (877) Derivatives 80,790 Operations with credit granting characteristics 1,159,187 Loan, lease and other credit operations 1,022,135 Securities 189,930 (Provision for expected credit loss) (52,878) Interbank and interbranch accounts 259,431 Other financial assets 60,567 Off-balance sheet 678,080 Financial guarantees 124,097 Credit commitments 553,983 Total 3,495,444 Amounts shown for credit risk exposure are based on gross book value and do not consider any collateral received or other added credit improvements. The contractual amounts of financial guarantees, credit commitments and credits to be released represent the maximum potential of credit risk in the event that a counterparty does not meet the terms of the agreement. The vast majority of credit commitments (mortgage loans, overdraft accounts and other pre-approved limits) mature without being drawn. As a result, the total contractual amount does not represent our real future exposure to credit risk or the liquidity needs arising from such commitments. I.V – Homogeneous portfolio of risk The Retail segment includes the businesses of Bank for Individuals, Payroll Loans, Cards and Financial Institutions, Vehicles for Individuals, Mortgage Loans, Retail Companies and Vehicles for Companies. In Retail, ITAÚ UNIBANCO HOLDING CONSOLIDATED has 130 Homogeneous groups: 86 in Stage 1, 29 in Stage 2 and 15 in Stage 3.The average risk concentration of credit operations for homogeneous groups is 0.8%. The breakdown of the gross book value of Operations with credit granting characteristics by maturity is shown below: 09/30/2025 Overdue as from 1 day 26,304 Current up to 3 months 267,742 Current from 3 to 12 months 271,161 Current over 1 year 646,858 Total 1,212,065 II - Market risk It is the possibility of incurring financial losses from changes in the market value of positions held by a financial institution, including the risks of transactions subject to fluctuations in currency rates, interest rates, share prices, price indexes and commodity prices, as set forth by CMN. Price Indexes are also treated as a risk factor group. 137 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 Market risk is controlled by an area independent from the business areas, which is responsible for the daily activities of (i) risk measurement and assessment, (ii) monitoring of stress scenarios, limits and alerts, (iii) application, analysis and testing of stress scenarios, (iv) risk reporting to those responsible within the business areas, in compliance with the governance of ITAÚ UNIBANCO HOLDING CONSOLIDATED, (v) monitoring of actions required to adjust positions and risk levels to make them realistic, and (vi) providing support for the safe launch of new financial products. The market risk structure categorizes transactions as part of either the banking portfolio or the trading portfolio, in accordance with general criteria established by CMN Resolution No. 4,557, of February 23, 2017, and BCB Resolution No. 111, of July 6, 2021, as amended. The trading portfolio consists of all transactions involving financial instruments and commodities, including derivatives, which are held for trading. The banking portfolio is basically characterized by transactions for the banking business, and transactions related to the management of the balance sheet of the institution, where there is no intention of sale and time horizons are medium and long term. Market risk management is based on the following metrics: • Value at risk (VaR): a statistical measure that estimates the expected maximum potential economic loss under normal market conditions, considering a certain time horizon and confidence level. • Losses in stress scenarios (Stress test): simulation technique to assess the behavior of assets, liabilities and derivatives of a portfolio when several risk factors are taken to extreme market situations (based on prospective and historical scenarios). • Stop loss/Max drawdown: metrics used to revise positions, should losses accumulated in a certain period reach a certain level. • Concentration: cumulative exposure of a certain financial instrument or risk factor, calculated at market value (MtM – Mark to Market). • Stressed VaR: statistical metric derived from the VaR calculation, with the purpose of simulating higher risk in the trading portfolio, taking returns that can be seen in past scenarios of extreme volatility. Management of Interest Rate Risk in the Banking Book (IRRBB) is based on the following metrics: • ΔEVE (Delta economic value of equity): difference between the present value of the sum of repricing flows of instruments subject to IRRBB in a base scenario and the present value of the sum of repricing flows of these instruments in a scenario of shock in interest rates. • ΔNII (Delta net interest income): difference between the result of financial operations of instruments subject to IRRBB in a base scenario and the result of financial operations of these instruments in a scenario of shock in interest rates. In addition, sensitivity and loss control measures are also analyzed. They include: • Mismatching analysis (GAPS): accumulated exposure by risk factor of cash flows expressed at market value, allocated at the maturity dates. • Sensitivity (DV01- Delta variation): impact on the fair value of cash flows when a 1 basis point change is applied to current interest rates or on the index rates. • Sensitivity to sundry risk factors (Greeks): partial derivatives of an option portfolio in relation to the prices of underlying assets, implied volatilities, interest rates and time. 138 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 In order to operate within the defined limits, ITAÚ UNIBANCO HOLDING CONSOLIDATED hedges transactions with customers and proprietary positions, including its foreign investments. Derivatives are commonly used for these hedging activities, which can be either accounting or economic hedges, both governed by the institutional policies of ITAÚ UNIBANCO HOLDING CONSOLIDATED. The structure of limits and alerts is aligned with the Board of Directors’ guidelines, and it is reviewed and approved on an annual basis. This structure has specific limits aimed at improving the process of monitoring and understanding risk, and at avoiding concentration. These limits are quantified by assessing the forecast balance sheet results, the size of stockholders’ equity, market liquidity, complexity and volatility, and ITAÚ UNIBANCO HOLDING CONSOLIDATED’s appetite for risk. The consumption of market risk limits is monitored and disclosed daily through exposure and sensitivity maps. The market risk area analyzes and controls the adherence of these exposures to limits and alerts and reports them in a timely manner to the Treasury desks and other structures foreseen in the governance. ITAÚ UNIBANCO HOLDING CONSOLIDATED uses proprietary systems to measure the consolidated market risk. The processing of these systems occurs in a high-availability access-controlled environment, which has data storage and recovery processes and an infrastructure that ensures business continuity in contingency (disaster recovery) situations. II.I - VaR - Consolidated ITAÚ UNIBANCO HOLDING VaR is calculated by Historical Simulation, i.e., the expected distribution for profits and losses (P&L´s Profit and loss statement) of a portfolio overtime, which can be estimated from past behavior of returns of market risk factors forthis portfolio. VaR is calculated at a confidence level of 99%, a historicalperiod of 4 years (1.000 business days) and a holding period of one day. Inaddition, in a conservative approach, VaR is calculated daily, with and without volatility weighting, and the final VaR is the more restrictive of the values given by the two methods. VaR total (historical simulation) (1) 09/30/2025 Average Minimum Maximum Total VaR VaR by risk factor group Interest rates 1,302 1,028 1,974 1,310 Currencies 39 22 63 42 Shares 46 36 89 40 Commodities 26 10 67 52 Effect of diversification - - - (380) Total risk 1,092 777 1,744 1,064 1) VaR by risk factor group considers information from foreign units.

Scenario II: Shocks of 25% in fixed interest curves rates, currency coupon, inflation, interest rate indexes and currency and share prices, both up and down, taking the highest resulting losses per risk factor. Scenario III: Shocks of 50% in fixed interest curves rates, currency coupon, inflation, interest rate indexes and currency and share prices, both up and down, taking the highest resulting losses per risk factor. The biggest losses by risk factor, in each scenario, were stated together with their impact on the result, net of tax effects, providing an overview of ITAÚ UNIBANCO HOLDING CONSOLIDATED’s exposure under exceptional scenarios. The sensitivity analyses of the banking and the trading portfolio are statics and do not take into account management’s quick response capacity (treasury and control areas), which triggers risk mitigating measures whenever a situation of loss or high risk is identified, thus minimizing the possibility of material losses. In addition, the study's sole purpose is to show the exposure to risk and the respective protective actions, considering the fair value of financial instruments, irrespective of the accounting practices adopted by ITAÚ UNIBANCO HOLDING CONSOLIDATED.

III - Liquidity risk Defined as the possibility that the institution may be unable to efficiently meet its expected and unexpected obligations, both current and future, including those arising from guarantees issued, without affecting its daily operations and without incurring significant losses. Liquidity risk is controlled by an area independent from the business area and responsible for establishing the reserve composition, estimating the cash flow and exposure to liquidity risk in different time horizons, and for monitoring the minimum limits to absorb losses in stress scenarios for each country where ITAÚ UNIBANCO HOLDING CONSOLIDATED operates. All activities are subject to verification by independent validation, internal control and audit areas. Liquidity management policies and limits are based on prospective scenarios and senior management’s guidelines. These scenarios are reviewed on a periodic basis, by analyzing the need for cash due to atypical market conditions or strategic decisions by ITAÚ UNIBANCO HOLDING CONSOLIDATED. 140 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 ITAÚ UNIBANCO HOLDING CONSOLIDATED manages and controls liquidity risk on a daily basis, using procedures approved in superior committees, including the adoption of liquidity minimum limits, sufficient to absorb possible cash losses in stress scenarios, measured with the use of internal and regulatory methods. Among the main regulatory liquidity indicators, the following indicators stand out: Liquidity coverage ratio (LCR): can be defined as a sufficiency index over a 30-day horizon, measuring the available amount of assets available to honor potential liquid outflows in a stress scenario. Net stable funding ratio (NSFR): can be defined as an analysis of funding available for the financing of longterm assets. Both metrics are managed by the liquidity risk area and they have limits approved by superior committees, as well as governance of action plans in possible liquidity stress scenarios. Under the LCR metric, ITAÚ UNIBANCO HOLDING CONSOLIDATED has High-quality Liquid Assets (HQLA), mainly made up of sovereign securities, reserves in central banks and cash. Net cash outflows are mainly made up of retail, wholesale funds, additional requirements, contractual and contingent obligations, offset by cash inflows from loans and other expected cash inflows. When the LCR in the period is above the 100% threshold means that has sufficient stable funds available to support losses under the standardized stress scenario for LCR. From the NSFR perspective, ITAÚ UNIBANCO HOLDING CONSOLIDATED has Available Stable Funding (ASF), mainly made up of capital and wholesale funds. The required stable funding (RSF) are mainly made up of loans and financing granted to clients.

The "Pillar 3", which details the Liquidity Ratios, can be viewed on the website www.itau.com.br/relacoes-cominvestidores/ en/, in the section Results and reports, Regulatory reports, Pillar 3. The document "Public Access Report – Liquidity Risk Management and Control Policy”, which details the guidelines established by the institutional regulation for liquidity risk control, which is not part of the financial statements, can be viewed on the website www.itau.com.br/relacoes-com-investidores/en/, in the section Itaú Unibanco, Corporate governance, Policies, Reports. IV - Operating risk Defined as the possibility of losses from failures, defects or shortcomings in internal processes, people or systems, or from external events impacting the realization of strategic, tactical or operational objectives. It includes the legal risk of inadequacies or defects in agreements signed by the institution, as well as sanctions for failing to comply with legal provisions and compensation to third parties for losses arising from the institution’s activities. The managers of the executive areas use corporate methods constructed and made available by the Compliance and Operational Risk area. As part of governance of the risk management process, consolidated reports on risk monitoring, controls, action plans and operating losses are periodically presented to the business areas’ executives. In line with the principles of CMN Resolution 4,557, of February, 23, 2017, the document entitled “Public Access Report – Integrated Operational Risk Management and Internal Controls”, a summarized version of the institutional operating risk management policy, may be viewed on the website www.itau.com.br/relacoes-com-investidores/en/, in the section Itaú Unibanco, Corporate governance, Policies, Reports. V - Insurance, private pension and premium bonds risks In addition to the risks inherent in financial instruments related to the Insurance, Private Pension and Premium Bonds portfolios, the operations carried out at ITAÚ UNIBANCO HOLDING CONSOLIDATED give rise to exposure to underwriting risk. Underwriting risk is the risk of significant deviations in the methodologies and/or assumptions used for pricing or provision of products, which can materialize in different ways, contrary to the expectations of the product offered: (i) Insurance: results from the change in risk behavior in relation to the increase in the frequency and/or severity of claims occurred, contrary to pricing estimates. (ii) Private pension: is observed in the increase in life expectancy or in deviation from the assumptions used in the technical reserves. (iii) Premium bonds: payment of premiums for securities drawn in series not paid in and/or administrative expenses higher than expected may materialize this risk. The measurement of underwriting risk exposure is based on the analysis of actuarial assumptions used in the recognition of liabilities and pricing of products through: i) monitoring of the evolution of equity necessary to mitigate insolvency or liquidity risk; ii) monitoring of portfolios, products and coverages, from the perspective of results, adherence to expected rates and expected behavior of loss ratio. Exposure to underwriting risk is managed and monitored according to the levels of risk appetite approved by Management and is controlled through indicators that allow the creation of stress scenarios and simulations of portfolio stress. 142 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 VI - Emerging risks Defined as those newly identified with a potentially material impact on the business in the medium and long term, but for which there are not enough elements yet for their complete assessment, due to the number of factors and impacts not yet totally known, since they have no precedents and therefore have never been addressed in the past. Their causes may arise from external events and result in the emergence of new risks or in the intensification of risks already monitored by ITAÚ UNIBANCO HOLDING CONSOLIDATED. Once identified, these risks are monitored and reassessed annually or on demand until they cease to pose a risk or until they can be adequately measured, in which case the other steps of risk management are then followed. This process is ensured by ITAÚ UNIBANCO HOLDING CONSOLIDATED’s governance, allowing these risks to be also incorporated into risk management procedures. Geopolitical, Climate and Cyber risks that have or have already had aspects considered as emerging risks can be given as examples. VII - Social, environmental and climate risks Social, environmental and climate risks are the possibility of losses due to exposure to social, environmental and/or climatic events related to the activities developed by ITAÚ UNIBANCO HOLDING CONSOLIDATED. Social, environmental and climatic factors are considered relevant to the business of ITAÚ UNIBANCO HOLDING CONSOLIDATED, since they may affect the creation of shared value in the short, medium and long term. The Policy of Social, Environmental and Climatic Risks (Risks SAC Policy) establishes the guidelines and underlying principles for social, environmental and climatic risk management, addressing the most significant risks for the institution’s operation through specific procedures. Actions to mitigate the Social, Environmental and Climatic Risks are taken based on the mapping of processes, risks and controls, monitoring of new standards related to the theme and recording of occurrence in internal systems. In addition to the identification, the phases of prioritization, response to risk, mitigation, monitoring and reporting of assessed risks supplement the management of these risks at ITAÚ UNIBANCO HOLDING CONSOLIDATED. In the management of Social, Environmental and Climatic Risks, business areas manage the risk in its daily activities, following the Risks SAC Policy guidelines and specific processes, with the support of specialized assessment from dedicated technical teams located in Credit, which serves the Wholesale segment, Credit Risk and Modeling, and Institutional Legal teams, that act on an integrated way in the management of all dimensions of the Social, Environmental and Climatic Risks related to the conglomerate’s activities. As an example of specific guidelines for the management of these risks, ITAÚ UNIBANCO HOLDING CONSOLIDATED has specific governance for granting and renewing credit in senior approval levels for clients in certain economic sectors, classified as Sensitive Sectors (Mining, Steel & Metallurgy, Oil & Gas, Textiles Industry and Retail Clothing, Paper & Pulp, Chemicals & Petrochemicals, Agribusiness - Meatpacking, Agribusiness - Crop Protection and Fertilizers, Wood, Energy, Rural Producers and Real Estate), for which there is an individualized analysis of Social, Environmental and Climate Risks. The institution also counts on specific procedures for the Institution’s operation (stockholders’ equity, branch infrastructure, technology and suppliers), credit, investments and key controls. SAC Risks area, Internal Controls and Compliance areas, in turn, support and ensure the governance of the activities of the business and credit areas that serves the business. The Internal Audit acts on an independent manner, assessing risk management, controls and governance. Governance also counts on the Social, Environmental and Climatic Risks Committee, whose main responsibility is to assess and deliberate about institutional and strategic matters, as well as to resolve on products, operations, services, among others involving the Social, Environmental and Climatic Risks. Climate Risk includes: (i) physical risks, arising from changes in weather patterns, such as increased rainfall, and temperature and extreme weather events, and (ii) transition risks, resulting from changes in the economy, as a result of climate actions, such as carbon pricing, climate regulation, market risks and reputational risks. 143 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 Considering its relevance, climate risk has become one of the main priorities for ITAÚ UNIBANCO HOLDING CONSOLIDATED, which supports the Task Force on Climate-related Financial Disclosures (TCFD) and it is committed to maintaining a process of evolution and continuous improvement within the pillars recommended by the TCFD. With this purpose, ITAÚ UNIBANCO HOLDING CONSOLIDATED is strengthening the governance and strategy related to Climate Risk and developing tools and methodologies to assess and manage these risks. ITAÚ UNIBANCO HOLDING CONSOLIDATED measures the sensitivity of the credit portfolio to climate risks by applying the Climate Risk Sensitivity Assessment Tool, developed by Febraban. The tool combines relevance and proportionality criteria to identify the sectors and clients within the portfolio that are more sensitive to climate risks, considering physical and transition risks. The sectors with the highest probability of suffering financial impacts from climate change, following the TCFD guidelines, are: energy, transport, materials and construction, agriculture, food and forestry products. c) Capital management governance ITAÚ UNIBANCO HOLDING CONSOLIDATED is subject to the regulations of BACEN, which determines minimum capital requirements, procedures to obtain information to assess the global systemic importance of banks, fixed asset limits, loan limits and accounting practices, and requires banks to conform to the regulations based on the Basel Accord for capital adequacy. Additionally, CNSP and SUSEP issue regulations on capital requirements that affect our insurance operations and private pension and premium bonds plans. The notes about capital were prepared in accordance with BACEN’s regulatory requirements and with internationally accepted minimum requirements according to the Bank for International Settlements (BIS). I - Composition and capital adequacy The Board of Directors is the body responsible for approving the institutional capital management policy and guidelines for the capitalization level of ITAÚ UNIBANCO HOLDING CONSOLIDATED. The Board is also responsible for the full approval of the ICAAP (Internal Capital Adequacy Assessment Process) report, the purpose of which is to assess the capital adequacy of ITAÚ UNIBANCO HOLDING CONSOLIDATED. The result of the last ICAAP, which comprises stress tests – which was dated December 2024 – indicated that ITAÚ UNIBANCO HOLDING CONSOLIDATED has, in addition to capital to cover all material risks, a significant capital surplus, thus assuring the solidity of the institution’s equity position. In order to ensure that ITAÚ UNIBANCO HOLDING CONSOLIDATED is sound and has the capital needed to support business growth, the institution maintains PR levels above the minimum level required to face risks, as demonstrated by the Common Equity Tier I, Tier I Capital and Total Capital ratios. 144 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 09/30/2025 Available capital (amounts) Common equity tier 1 (CET 1) 195,917 Tier 1 215,466 Total capital (PR) 238,430 Risk-weighted assets (amounts) Total risk-weighted assets (RWA) 1,454,242 Risk-based capital ratios as a percentage of RWA Common equity tier 1 ratio (%) 13.5% Tier 1 ratio (%) 14.8% Total capital ratio (%) 16.4% Additional CET1 buffer requirements as a percentage of RWA Capital conservation buffer requirement (%) 2.5% Countercyclical buffer requirement (%) 0.1% Bank G-SIB and/or D-SIB additional requirements (%) 1.0% Total of bank CET1 specific buffer requirements (%) 3.6% At 09/30/2025, the amount of perpetual subordinated debt that makes up Tier I capital is R$ 18,599 and the amount of subordinated debt that makes up Tier II capital is R$ 21,813. The Basel Ratio reached 16.4% at 09/30/2025, a reduction of 0.1 p.p. in relation to that calculated at 12/31/2024. The variation reflects the effects of interest payments on capital and additional dividends, share repurchase and growth in risk-weighted assets, offset by the positive impact of income in the period. Additionally, ITAÚ UNIBANCO HOLDING CONSOLIDATED has a surplus over the required minimum Total Capital of R$ 122,091, well above the Capital Buffer requirement of R$ 51,806, widely covered by available capital. The fixed assets ratio indicates the commitment percentage of adjusted Total Capital with adjusted permanent assets ITAÚ UNIBANCO HOLDING CONSOLIDATED falls within the maximum limit of 50% of adjusted Total Capital, established by BACEN. At 09/30/2025, fixed assets ratio reached 17.7%, showing a surplus of R$ 77,101. Further details on Risk and Capital Management of ITAÚ UNIBANCO HOLDING CONSOLIDATED and indicators of the Global Systemic Importance Index, which are not included in the financial statements, can be viewed at www.itau.com.br/relacoes-com-investidores/en, in the section Results and reports, Regulatory reports, Pillar 3 and Global Systemically Important Banks. II - Risk-weighted assets (RWA) For calculating minimum capital requirements, RWA must be obtained by taking the sum of the following risk exposures: • RWACPAD = portion related to exposures to credit risk, calculated using standardized approach. • RWACIRB = portion related to exposures to credit risk, calculated according to internal credit risk rating systems (IRB - Internal Ratings-Based approaches), authorized by the Central Bank of Brazil. • RWAMPAD = portion related to the market risk capital requirement, calculated using standardized approach. • RWAMINT = portion related to the market risk capital requirement, calculated according to internal model approaches, authorized by the Central Bank of Brazil. 145 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 • RWAOPAD = portion related to the operational risk capital requirement, calculated using standardized approach. RWA 09/30/2025 Credit risk (excluding counterparty credit risk) 1,138,362 Of which: standardized approach for credit risk 1,062,874 Of which: foundation internal rating-based approach (F-IRB) - Of which: advanced internal rating-based approach (A-IRB) 75,488 Counterparty credit risk (CCR) 29,491 Of which: standardized approach for counterparty credit risk (SA-CCR) 20,812 Of which: other CCR 8,679 Equity investments in funds - look-through approach 4,360 Equity investments in funds - mandate-based approach - Equity investments in funds - fall-back approach 1,330 Securitization exposures in banking book 9,528 Market Risk 61,765 Of which: standardized approach (RWAMPAD) 75,499 Of which: internal models approach (RWAMINT) 33,578 Operational Risk 143,006 Payment services risk (RWASP) NA Amounts below the thresholds for deduction 66,400 Total 1,454,242 III - Recovery plan In response to the latest international crises, the Central Bank published Resolution No. 5,187, which requires the development of a Recovery and exit planning (PRSO) by financial institutions within Segment 1, with total exposure to GDP of more than 10%. This plan aims to reestablish adequate levels of capital and liquidity above regulatory operating limits in the face of severe systemic or idiosyncratic stress shocks. In this way, each institution could preserve its financial viability while also minimizing the impact on the National Financial System. IV - Stress testing The stress test is a process of simulating extreme economic and market conditions on ITAÚ UNIBANCO HOLDING CONSOLIDATED’s results, liquidity and capital. The institution has been carrying out this test in order to assess its solvency in plausible scenarios of crisis, as well as to identify areas that are more susceptible to the impact of stress that may be the subject of risk mitigation. For the purposes of the test, the economic research area estimates macroeconomic variables for each stress scenario. The elaboration of stress scenarios considers the qualitative analysis of the Brazilian and the global conjuncture, historical and hypothetical elements, short and long term risks, among other aspects, as defined in CMN Resolution 4,557. In this process, the main potential risks to the economy are assessed based on the judgment of the bank's team of economists, endorsed by the Chief Economist of ITAÚ UNIBANCO HOLDING CONSOLIDATED and approved by the Board of Directors. Projections for the macroeconomic variables (such as GDP, basic interest rate, exchange rates and inflation) and for variables in the credit market (such as raisings, lending, rates of default, spread and fees) used are based on exogenous shocks or through use of models validated by an independent area. Then, the stress scenarios adopted are used to influence the budgeted result and balance sheet. In addition to the scenario analysis methodology, sensitivity analysis and the Reverse Stress Test are also used. 146 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 ITAÚ UNIBANCO HOLDING CONSOLIDATED uses the simulations to manage its portfolio risks, considering Brazil (segregated into wholesale and retail) and External Units, from which the risk-weighted assets and the capital and liquidity ratios are derived. The stress test is also an integral part of the ICAAP, the main purpose of which is to assess whether, even in severely adverse situations, the institution would have adequate levels of capital and liquidity, without any impact on the development of its activities. This information enables potential offenders to the business to be identified and provides support for the strategic decisions of the Board of Directors, the budgeting and risk management process, as well as serving as an input for the institution’s risk appetite metrics. V - Leverage ratio The Leverage Ratio is defined as the ratio between Tier I Capital and Total Exposure, calculated according to BACEN Circular 3,748, which minimum requirement is 3%. The ratio is intended to be a simple measure of nonrisk- sensitive leverage, and so it does not take into account risk weights or risk mitigation. Note 28 - Supplementary Information a) Insurance policy ITAÚ UNIBANCO HOLDING CONSOLIDATED, despite the reduced risk exposure due to the low physical concentration of its assets, has a policy of insuring valuables and assets at amounts considered sufficient to cover possible losses. b) Foreign currency Equity balances in Reais linked to the foreign currencies were as follows: 09/30/2025 Permanent foreign investments 100,974 Net balance of other assets and liabilities indexed to foreign currency, including derivatives (78,555) Net foreign exchange position 22,419 The net foreign exchange position, considering the tax effects on the net balance of other assets and liabilities indexed to foreign currencies, reflects the low exposure to exchange variations. c) Agreements for offsetting and settlement of liabilities within the scope of the National financial system Offset agreements are in force in relation to derivative contracts, as well as agreements for the offsetting and settlement of receivables and payables pursuant to CMN Resolution No. 3,263, of February 24, 2005, the purpose of which is to enable the offsetting of credits and debits with the same counterparty, and where the maturity dates of receivables and payables can be brought forward to the date of an event of default by one of the parties or in the event of bankruptcy of the debtor. 147 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 d) Regulatory non-recurring result Presentation of regulatory non-recurring result of ITAÚ UNIBANCO HOLDING and ITAÚ UNIBANCO HOLDING CONSOLIDATED, net of tax effects, in accordance with the criteria established by BCB Resolution No. 2/2020: 01/01 to 09/30/2025 Regulatory non-recurring results (225) Restructuring (611) Provision for tax 507 Other (121) e) Subsequent event Issuance of Subordinated Perpetual Financial Bills On October 08, 2025, ITAÚ UNIBANCO HOLDING CONSOLIDATED issued R$ 3 billion in Subordinated Perpetual Financial Bills, in negotiations with professional investors.

Introduction We have reviewed the accompanying condensed balance sheet of Itaú Unibanco Holding S.A. ("Bank") as at September 30, 2025 and the related condensed statements of income, comprehensive income, changes in stockholders' equity and cash flows for the nine-month period then ended, as well as the accompanying condensed consolidated balance sheet of Itaú Unibanco Holding S.A. and its subsidiaries ("Consolidated") as at September 30, 2025 and the related condensed consolidated statements of income, comprehensive income, changes in stockholders' equity and cash flows for the nine-month period then ended, and selected notes, comprising a summary of significant accounting policies. Management is responsible for the preparation and presentation of these parent company and consolidated condensed financial statements in accordance with accounting practices adopted in Brazil applicable to institutions authorized to operate by the Brazilian Central Bank(BCB). Our responsibility is to express a conclusion on these condensed financial statements based on our review. Scope of review We conducted our review in accordance with Brazilian and International Standards on Reviews of Interim Financial Information (NBC TR 2410 - "Review of Interim Financial Information Performed by the Independent Auditor of the Entity" and ISRE 2410 - "Review of Interim Financial Information Performed by the Independent Auditor of the Entity", respectively). A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Brazilian and International Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion. Conclusion Based on our review, nothing has come to our attention that causes us to believe that the accompanying parent company and consolidated condensed financial statements referred to above do not present, in all material respects, in accordance with accounting practices adopted in Brazil, applicable to institutions authorized to operate by the Brazilian Central Bank (BCB). 150 Itaú Unibanco Holding S.A. – Condensed Financial Statements – September 30, 2025 ��Itaú Unibanco Holding S.A. Emphasis of matters Comparative figures We draw attention to Note 2(a) to the parent company and consolidated condensed financial statements, which describes that these statements were prepared in accordance with accounting practices adopted in Brazil, applicable to institutions authorized to operate by the Brazilian Central Bank, which consider the exemption from presenting comparative figures in the parent company and consolidated condensed financial statements for the quarter and nine-month period then ended September 30, 2025, as provided for in Resolution no 4,966 of the National Monetary Council and in Resolution nº 352 of the Brazilian Central Bank . Our conclusion is not qualified in respect of this matter. Other matters Supplementary information as of January 1, 2025 As presented in notes no 2 a) and b) to these parent company and consolidated condensed financial statements, unaudited supplementary information as of January 1, 2025 was included in the Condensed Consolidated Balance Sheet and in the parent company and consolidated Condensed Statement of Changes in Equity. Condensed Statement of added value The condensed financial statements referred to above include the parent company and consolidated statements of added value for the nine-month period ended at September 30, 2025. These statements are the responsibility of the Bank's management and are presented as supplementary information. These statements have been subjected to review procedures performed together with the review of the condensed financial statements for the purpose of concluding whether they are reconciled with the condensed financial statements and accounting records, as applicable, and if its form and content are in accordance with the criteria defined in the accounting standard CPC 09 - "Statement of Value Added". Based on our review, nothing has come to our attention that causes us to believe that these statements of added value have not been properly prepared, in all material respects, in accordance with the criteria established in this accounting standard, and that they are consistent with the parent company and consolidated condensed financial statements taken as a whole.
