• The cost of credit increased 2.5% in the quarterly comparison and totaled R$10.0 billion. The cost of credit over the average loan portfolio ratio re- mained at the same level as in the previ- ous quarter, at 2.7%. • Commissions and fees and result from insurance operations declined 5.7%. There was a reduction in revenues due to the following seasonal effects: (i) lower card transaction volumes, affect- ing payments and collections and issu- ance; and (ii) performance fees, which were recognized in the second and fourth quarters. • Non-interest expenses are seasonally lower in the first quarter and decreased 5.0% in the quarter. With this earnings dynamics, our efficiency ratio closed the first quarter at 37.1% on a consolidated basis. In Brazil, the ratio ended at 34.9%, the lowest level in the historical series. Management commentary Executive Summary Management Discussion & Analysis > Executive Summary In the first quarter of 2026, the recurring managerial result reached R$12.3 billion, with a 0.3% quarter on quarter decrease. Excluding the effect of the earlier divi- dend payment, which took place at the end of 2025, the recurring managerial re- sult would have been R$12.7 billion, growth of 3.2% in the quarter. The recur- ring managerial return on equity was 24.8% on a consolidated basis and 26.4% in operations in Brazil. • The loan portfolio decreased 0.5% on a consolidated basis and increased 0.3% in Brazil in the quarter. Excluding the effect of foreign exchange variation, the loan portfolios would have grown 1.2% in the consolidated and 1.0% in Brazil. Compared to the same period of the previous year, growth rates were 7.2% on a consolidated basis and 7.8% in Brazil. Excluding the effect of exchange rate variation, the loan portfolios would have grown 9.0% on a consolidated basis and 9.2% in Brazil. • The loan portfolio of individuals in Brazil grew 1.1% in the quarter, with highlights of 3.3% growth in mortgage loans and 4.4% in payroll, the latter due to 19.1% growth in private payroll. In credit cards, there was a 2.1% reduction due to the typical seasonality of the first quarter. • In terms of quarterly comparison, the financial margin with clients declined 0.7%, and excluding the effect of the ear- lier dividend payment that happened at the end of 2025, it would have posted growth of 1.1%. Regarding the spread- sensitive margin, there was a positive im- pact of a better product mix and higher average volume of assets. These positive effects, were partially compensated by the lower number of days in the quarter. • The total nonperforming loans 15–90 days overdue ratio (NPL 15–90), increased 0.1 p.p. and closed the quarter at 1.7%. This increase occurred mainly due to the typical seasonality of the first quarter, which resulted in a 0.23 p.p. increase in the individuals indicator in Brazil. • The nonperforming loans over 90 days overdue ratio (NPL 90) on a consolidated basis, remained stable at 1.9% in the quar- ter. The Brazil ratio closed the quarter at 2.1%, with an increase of 0.1 p.p., both in the quarterly and annual comparisons, mainly related to the increase in very small, small and middle market compa- nies, due to the normalization of the ratio as expected. The recurring managerial result posted growth of 10.4%. The recurring mana- gerial return showed an annual increase of 2.3 p.p. • The financial margin with clients in- creased 4.5% in the annual comparison, due to loan portfolio growth, a higher liabilities’ margin, and a better product mix. • The financial margin with the market declined 11.2%, as a result of the in- crease in the hedge cost of the capital ratio. • The cost of credit increased 4.5% due to the growth of the loan portfolio, with stability in the cost of credit over the loan portfolio ratio, which remained at 2.7%. • Commissions and fees and result from insurance operations increased 5.3%. There was an increase in the volume of card issuing activities, higher asset management revenues, and higher rev- enues from investment banking and brokerage services. The growth in the result from insurance, pension plan and premium bonds also noteworthy, driven by the increase in earned premiums and revenues from commissions from third- party services. • Non-interest expenses increased 4.8%, while the trailing 12-month effi- ciency ratio stood at 38.0% on a consol- idated basis and 36.2% in Brazil.

The reduction was mainly explained by the negative impact of the earlier dividend payment that occurred at the end of the fourth quarter of 2025. Excluding this negative impact, the financial margin with clients would have increased 1.1%. There was an increase in the spread-sensitive margin, with emphasis on: (i) the positive effect of a better product mix, due to the higher relative growth of more profitable products, such as overdraft facilities; and (ii) a higher average volume of assets, driven by the increase in the average profitable portfolio, especially mort- gage loans, private payroll portfolios, as well as the increase in the average balance of the very small, small and middle-market companies portfolio, mainly related to government programs for small and middle market companies. These positive effects were partially off- set by the seasonal effect of the lower number of days in the quarter. Compared to the previous year, financial margin with clients grew 4.5%, related to the in- crease in the loan portfolio, the higher liabilities’ margin, and the better product mix. This growth was partially offset by the negative impact of the earlier dividend payment and low- er receipts from structured operations in the wholesale business. The financial margin with the market increased by 37.4% in the quarter, mainly due to the higher result obtained by the trading desk. Compared to the previous year, there was a de- crease of 11.2%, due to the increase in the hedge cost of the capital ratio.

13 Cost of Credit Management Discussion & Analysis > Cost of Credit Cost of credit closed the first quarter of 2026 at R$10.0 billion and increased 2.5% from the previous quarter. This increase was due to the Retail Business in Brazil, as the concen- tration of household spending in this period generated an increase in the short-term over- due ratio and, consequently, led to higher expected loss expenses in the segment. In addi- tion, the typical first-quarter seasonality also negatively affected the credit recovery of the segment. There was a decline in discounts granted in Wholesale Business in Brazil, mainly due to the impact of the sale of a portfolio of a specific client that occurred in 4Q25, which increased the volume of discounts granted in the previous quarter. Compared to the previous year, the cost of credit increased 4.5%. This change occurred in line with the growth of the loan portfolio, while the cost of credit over the loan portfolio remained stable. Recovery of Loans Written off as Losses and Sales of Financial Assets In the first quarter of 2026, there were sales of portfolios that were already recognized as losses, in both the Retail and Wholesale Busi- nesses in Brazil, totaling R$1.2 billion, with a positive impact of R$39 million on the recovery of loans written off as losses and R$21 million on the recurring managerial result. These sales did not impact credit quality indicators. In the quarter, we sold active portfolios without risk retention to non-related companies in the amount of R$2.9 million, which would have been more than 90 days overdue, and portfolios in Latin America in the amount of R$29 million, without more than 90 days overdue. These sales of active portfolios did not impact the long overdue ratio and generated a positive impact of R$3.7 million on the cost of credit and R$1.8 million on the recurring managerial result.

This increase was related to the 0.23 p.p. growth in the individuals loan portfolio ratio in Brazil, due to the typical seasonality of the period, when household spending is concentra- ted, closing the quarter at 3.0%. The nonperforming loans 90 days overdue ratio (NPL 90) remained stable for another con- secutive quarter. In Brazil, the individuals ratio remained stable compared with the previous quarters of 2025. There was a 0.1 p.p. increase compared to the previous quarter in the ratio for very small, small and middle market companies in Brazil, which continued the normalization cycle of the indicator due to the end of grace periods of government programs.

This portfolio was composed of loan operations and securities whose original contractual terms were signifi- cantly modified due to the deterioration of their credit quality and presented a reduction of 1.5% compared to December 2025. The renegotiated loans and securities portfolio decreased by 1.0% compared to December 2025 and closed the first quarter of 2026 at R$34.8 billion. In both cases, the reductions were related to the retail portfolio, due to the reduction of the personalized credit portfo- lio. The NPL Creation over the loan portfolio remained at 0.7%, at a historically low level, with relative stability across all segments. As a result, NPL Creation decreased on a quarterly comparison and ended the first quarter at R$9,694 million. Loan portfolio write-offs increased by 17.4% from the previous quarter, due to the Retail Business in Brazil, which closed the quarter at R$8.9 billion, in line with the behavior of NPL creation over the last three quarters of 2025. The ratio between loan operations written off and the average balance of the loan portfolio closed the first quarter at 0.7%, an increase of 0.1 p.p. from the previous quarter.

16 Credit Quality Management Discussion & Analysis > Credit Quality Credit Quality Indicators in CMN Resolution No. 4,966/21 Below we present the credit quality indicators introduced by CMN Resolution No. 4,966/21, which classifies financial instruments into three stages: Stage 1: Applicable to financial instruments without a significant increase in credit risk. 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: • Non-performing loans 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. Loan portfolio classified as Stage 2 increased by 0.12 p.p. from the previous quarter, however, it remained at the same level as in the other quarters of 2025. The portfolio classified as Stage 3 also increased, both in total and in corporate, related to the inclusion of specif- ic clients from the companies segment, due to the deterioration in the credit rating of these clients. The coverage level of Stage 3 was defined based on our expected loss criteria and considered collateralization and recovery prospects of the loans.

There was a reduction in fund management fees, as the previous quarter included the recognition of performance fees, which were concentrated in the second and fourth quarters of the year. There was also a reduction in revenues from card issuance and from payments and collections (which include acquiring operations), due to lower tran- saction volumes, reflecting the typical first-quarter seasonality. Revenues from investment banking operations also decreased, as a result of lower market activity during the period. Compared to the same period of the previous year, commissions and fees and result from insurance operations increased 5.3%, mainly due to increases in: (i) asset management, driven by higher fund balances; (ii) higher volumes in investment banking and brokerage services; and (iii) higher result from insurance operations, driven by the increase in earned premiums and in commissions from third-party insurance services. On the other hand, there was a decrease in payments and collections, especially due to the increase in the cost of funding in the acquiring operation.

Compared to the same period of the previous year, revenues increased 1.5%, mainly as a result of the increase in credit card transaction volume, partially offset by higher expenses on re- wards programs, in line with the strategy of offering more benefits to clients as they increase their engagement with the bank.

(1) Revenues from Insurance, Pension Plan and Premium Bonds Operations net of retained claims. Payments and collections revenues de- creased 9.2% in the quarter, related to the reduction in the transaction value of acquir- ing operations, which are seasonally lower in the first quarter of the year. The 7.0% decrease, compared to the same period of the previous year, occurred mainly due to the increase in the cost of funding in acquiring operations, in addition to a change in the revenue mix, which affected only the comparison with the last year, but did not impact the variation in the quarter. Note: As of 1Q26, we started to consider new installment credit products in the card transaction volume of the issuing business.

18 Revenues from current account services for individuals decreased by 5.1% in the quarter and declined 21.5% from the same period of the previous year. Both movements reflected the bank’s proactive agenda of offering increasingly better conditions to clients, as they expand their rela- tionship with the bank. Advisory Services and Brokerage Revenue from advisory and brokerage services decreased 13.5% in the quarter, due to lower volumes in investment banking opera- tions, especially in fixed income securities issuance. On the other hand, brokerage revenues increased, both in individuals and insti- tutional brokerage services. Compared to the same period of the previous year, revenues in- creased 18.9%, mainly due to higher revenues from individuals and institutional brokerage services. There was also an increase in investment banking gains, related to mergers and acquisitions and fixed income securities issuance. Result from Insurance, Pension Plan and Premium Bonds The result from insurance, pension plan and premium bonds remained stable from the previous quarter. The increase in re- tained claims, mainly in the portfolios of protected card and payment, group life and credit life, was offset by higher sales in the mortgage and credit life segments. Current Account for Individuals Fund Management Fund management fees decreased 11.0% in the quarter, due to the recognition of performance fees, which occurred in the pre- vious quarter. The recognition of these revenues occurs in the second and fourth quarters of the year. Fixed Income: In 1Q26, in Local Fixed Income, we were ranked 1st in the ANBIMA Origination Ranking, totaling R$28.9 billion in originated volume, with a 25.2% market share; and 1st in Distribution, totaling R$15.7 billion in distributed volume, with a 29.4% market share. Equities: In 1Q26, we participated in 6 transactions, totaling R$1.0 billion in volume (12.3% market share), ranking 2nd by number of transactions and 3rd by transaction volume in the Dealogic ranking. Mergers and Acquisitions: In 1Q26, we advised on 8 transactions in Brazil, totaling R$17.8 billion (23.4% market share), ranking 1st by number of transactions and 4th by transaction volume in the Dealo- gic ranking. Stable +17.2% 1Q26 x 4Q25 R$3.0 bn 1Q26 x 1Q25 The increase of 17.2% from the same peri- od of the previous year was due to the growth in: (i) revenue from commissions due to third-party insurance services; and (ii) earned premiums, mainly in individual life, credit life, mortgage and protected card and payment, driven by higher sales and the evolution of the portfolio. These movements were partially offset by the increase in retained claims, in the portfoli- os of individual life, credit life, protected card and payment and property. Result from Insurance, Pension Plan and Premium Bonds Commissions and Fees and Insurance Management Discussion & Analysis > Commissions and Fees and Insurance Compared to the first quarter of 2025, fund management fees in- creased 13.0%, mainly due to the growth in balances during the period.
19 Non-interest Expenses Management Discussion & Analysis > Non-interest expenses Non-interest expenses were seasonally lower in the first quarter and decreased by 5.0% in total and by 5.6% in Brazil, compared to the previous quarter. The reduction in personnel expenses, which impacts Commercial and Administrative, Transactional, and Technology expenses, was due to lower provisions for vacation and 13th salary payments to employees. In addition to this effect, the reduction in transactional expenses was mainly related to lower operating expenses, civil provisions and lower expenses with third-party expenses. With regard to other expenses, there was a reduction in marketing, advisory, and consult- ing expenses, which are seasonally lower in the first quarter. In Latin America, the de- crease occurred due to lower credit card expenses in Uruguay, which were seasonally lower in the period, partially offset by higher consulting expenses in Paraguay. Compared to the first quarter of 2025, non-interest expenses increased by 4.8% in total and by 5.2% in Brazil. The increase in personnel expenses, which impacts Commercial and Administrative, Transactional, and Technology expenses, occurred due to the effects of the collective wage agreement, with a 5.68% salary adjustment as of September 2025. The growth in Technology expenses occurred due to the increase in cloud processing volume and higher spending on systems development. In Latin America, the increase occurred mainly due to higher expenses in Uruguay, related to higher profit sharing expenses and card volume.

20 Balance Sheet Management Discussion & Analysis > Balance Sheet Total assets increased 3.3% compared with the previous quarter of 2025, mainly due to the growth of: (i) R$62.9 billion in securities and derivatives, especially government securities; (ii) R$16.7 billion in interbank investments, as a result of the increase in securities pur- chased under agreements to resell; and (iii) R$14.8 billion in inter- bank and interbranch accounts, mainly due to the Central Bank of Brazil deposits. The 13.4% increase, from the same period of the previous year, occurred especially due to the increases of: (i) R$116.5 billion in interbank investments; (ii) R$99.4 billion in securities and derivatives, mainly in pension plan funds and government securities; and (iii) R$80.7 billion in operations with credit granting characteris- tics, due to the growth of the portfolio across all segments in Brazil, in addition to the increase of the portfolio in Latin America. The increase in liabilities in the quarter occurred mainly due to the rise of R$72.2 billion in securities sold under repurchase agreements, in addition to an increase of R$21.7 billion in other liabilities, resul- ting from the seasonal growth of taxes. These movements were par- tially offset by the reduction in deposits balance, especially in de- mand and in savings deposits. From the same period of the previous year, the 13.4% increase occurred due to the rise of R$120.0 billion in securities sold under repurchase agreements, in addition to the growth of R$80.6 billion in deposits, mainly in the time deposits. The- re was also an increase of R$49.2 billion in technical provisions for insurance, pension plan and premium bonds, mainly due to the in- crease in the remuneration of provisions, in addition to the net gain of pension plan funds in the period. Stockholders' equity increased by R$4.0 billion in the quarter and grew by R$6.2 billion compared to the same period of the previous year. Both movements occurred mainly due to the appropriation of net income in the period, partially offset by the payment of divi- dends and interest on capital, in addition to the acquisition of trea- sury shares.

Growth of 11.6% in the last 12 months occurred mainly due to the increases of: (i) R$74.7 billion in funds from bills, structured operations certificates and repurchase agreements, mainly in financial, real estate and agribusiness bills; and (ii) R$72.2 billion in time deposits, especially in Brazil. Assets under custody grew by 4.8% in the quarter and 22.6% in the last 12 months. In both comparisons, the growth was driven by the increase of: (i) own products, mainly in treasury and in offshore products; and (ii) open platform, driven by the rise in fixed income products and pension plan funds.

Capital Ratios Main changes in the quarter Referential Equity: growth of 0.8% driven by the net income for the period, partially offset by the payment of interest on own capital and stock buyback (related to the share-based payment plans). The com- mon equity increased by 0.6%. RWA: increased by R$55.3 billion, mainly due to the impact of regula- tory changes related to credit and operational risks, in addition to the growth of required capital for operational and market risks. BIS ratio: decreased by 0.4 p.p. from December 2025, mainly due to the implementation of regulatory changes related to credit and ope- rational risks, the growth of risk-weighted assets, the payment of interest on own capital and stock buyback, effects partially offset by the net income for the period. In March 2026, the BIS ratio was 3.2 p.p. above the minimum required, including capital buffers. Liquidity Ratios These ratios are calculated based on the methodology defined by the Brazili- an Central Bank, which is in line with the Basel III international guidelines. Liquidity Coverage Ratio (LCR) The average LCR in the quarter reached 195.1%, above the 100% limit, which means that we have sufficient resources consistently available to cover losses in stress sce- narios. Net Stable Funding Ratio (NSFR) The NSFR was 122.0% 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 2026, 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 statisti- cal metric that quantifies the potential economic losses which are expected in normal market conditions.

25 Results by Business Segment Management Discussion & Analysis > Results by Business Segment The recurring managerial result increased 5.1% compared with the previous quarter of 2025, due to the higher financial margin with clients, mainly as a result of an improved product mix, due to the relative growth of more profitable products, in addition to the higher average credit volume, particularly in the mortgage loans, private payroll and government programs for small and Middle market companies portfolios. There was also a decrease in non-interest expenses, due to the seasonal effect of the first quarter of the year, resulting from the reduc- tion in provisions for employees’ vacation and 13th salary. These movements were partially offset by the higher cost of credit, due to the increase in expected loss expenses, as a result of the seasonal growth in short-term delinquency, as well as the lower recovery of loans writ- ten off as losses, a typical movement of the first quarter. There was also a reduction in com- missions and fees, as a result of the seasonal decrease in transaction volumes in card issuance and in the acquiring operation. The recurring managerial result increased 29.4% from the same period of the previous year. This movement occurred mainly due to: (i) an increase in the financial margin with clients, as a result of an improved product mix and higher average credit volume; (ii) an increase in in- surance revenues, mainly due to the growth in revenues from third-party services and to the increase in earned premiums; and (iii) a de- crease in the cost of credit, due to the reduction in discounts granted. On the other hand, there was an increase in non-interest expenses due to higher commercial and administrative expenses, due to the effects of the collective wage labor agreement, in addition to a reduction in commissions and fees, due to the increase in the cost of funding in acquiring.

26 The recurring managerial result decreased by 5.6% from the previous quarter of 2025, mainly due to the lower financial margin with clients, as a result of the calendar effect, the seasonal reduction in the first quarter in the volume of liabilities, as well as the lower re- sult from structured operations. Commissions and fees decreased driven by lower fund management fees, reflecting the recognition of performance fees in the previous quarter, in addition to lower gains from investment banking. On the other hand, the cost of credit decreased due to lower expected loss expenses in Brazil and in Latin America, as well as a reduction in non-interest expenses, which were seasonally lower in the first quarter. The recurring managerial result decreased 0.6% compared to the same quarter of the pre- vious year, due to the lower financial margin with clients resulting from lower results from structured operations, in addition to the increase in the cost of credit, due to higher ex- pected loss expenses in Brazil. On the other hand, commissions and fees increased due to higher gains from brokerage and investment banking.

The calcula- tion bases of returns were adjusted by the dividends proposed after the balance sheet closing dates, which have not yet been approved at the annual Stockhol- ders' or Board meetings. Recurring Managerial Return on Average Assets – Annualized Obtained by dividing the Recurring Mana- gerial Result by the Average Assets.

Average asset portfolio Includes the portfolio of credit and pri- vate securities, net of loans more than 60 days overdue, but excluding the ef- fects of average exchange rate varia- tions 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 tran- sactions 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.

Currency Includes cash, bank deposits of instituti- ons without reserve requirements, fo- reign 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 consolida- ted 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 peri- od of four years (1000 business days) and a holding period of one day.

Possible impacts are being assessed and will be completed until the beginning of the standard effectiveness. • CMN Resolution No. 5,281/26 - Virtual assets - Establishes criteria for the recognition and measurement of assets and liabilities related to the provision of services with virtual assets, prospectively applicable from January 1, 2027, and any effects should be recognized as a counterpart to accumulated profit or loss, net of tax effects. Possible impacts are being assessed and will be completed until the beginning 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. 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: 60

Miami Branch, which functional currency is the US Dollar. 61
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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. 62
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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 Financial assets are classified and subsequently measured in the following categories: • Amortized cost (AC): used when financial assets are managed to obtain contractual cash flows, consisting solely of payments of principal and interest. • Fair value through other comprehensive income (FVOCI): used when financial assets are held both for obtaining contractual cash flows, consisting solely of payments of principal and interest, and for sale. • Fair value through profit or loss (FVPL): used for financial assets that do not meet the aforementioned criteria above and the financial assets irrevocably designated in the initial recognition at fair value through profit or loss. The category depends on the business model under which the financial assets are managed and the characteristics of their cash flows. • Business models: are established according to the objectives of the business areas, considering the risks that affect their performance of the business model; how it is assessed and reported to Management and how the managers of the business are compensated. • Contractual cash flow characteristics: tested individually to validate whether the cash flows generated by the financial instrument constitute only principal and interest payment (consideration for the time value of money, credit risk and profit margin). ITAÚ UNIBANCO HOLDING CONSOLIDATED assesses mainly the following situations: changes in rate due to modification in credit risk; interest rates determined by regulatory bodies; leverage; embedded derivatives; and term extension clauses and exchange rate variation. If contractual terms introduce risk exposure or cash flow volatilities, the financial asset does not constitute only principal and interest payment and is classified in the category Fair value through profit or loss. Financial assets designated as fair value through profit or loss: ITAÚ UNIBANCO HOLDING CONSOLIDATED has financial assets designated at fair value through profit or loss to reduce an accounting mismatch. 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. 63
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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. Level 3: Inputs that are not observable for the asset or liability allowing the use of internal models and techniques. The portion of the fair value variation resulting from changes in ITAÚ UNIBANCO HOLDING CONSOLIDATED own credit risk is recognized in other comprehensive income, for 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 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. 64
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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. 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. 65
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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. 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. 66
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 • 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. 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. 67
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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 and rights for acquisition of payrolls. Intangible assets are measured at amortized cost in the 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. 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. 68
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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. 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. 69
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 • 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. 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.

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. 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. 78
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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. 79

Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 Note 11 - Provisions, contingent assets and contingent liabilities The accounting policy on provisions, contingent assets and contingent liabilities is presented in Note 2c XII. 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. 97
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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.

Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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 fixed- income 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.

Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 Sensitivity analysis of level 3 operations The fair value of financial instruments classified in Level 3 is measured through valuation techniques based on correlations and associated products traded in active markets, internal estimates and internal models. 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 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 113
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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 CONSOLIDATED 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.

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.

Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 Note 22 - Post-employment benefits The accounting policy on post-employment benefits is presented in Note 2c XIV. 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 03/31/2026 03/31/2025 Demographic Mortality table (1) AT-2000 AT-2000 Financial Nominal discount rate (2) 11.70% p.a. 11.59% p.a. Financial Inflation (3) 4.00% p.a. 4.00% p.a. 1) Correspond to those disclosed by SOA - Society of Actuaries, with the general application of a 10% increase, according to the adherence to the plan's population, in the probability of survival in relation to the respesctive basic tables. 2) 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. 3) Long-term inflation projected. 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. 126
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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. 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. 127

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 appointment, before BACEN, of the Chief Risk Officer (CRO), with assignment of roles, responsibilities, and independence requirements. 132
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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 non- negotiable. 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.

Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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-com- investidores/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. 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. 134
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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. 135
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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. The concentrations are monitored continuously for economic sectors and largest debtors, allowing preventive measures to be taken to avoid the violation of the established limits. The rating models for large companies incorporate Report on Environmental, Social, and Climate Risks and Opportunities (GRSAC) through a questionnaire, which considers: • Social: events associated with the violation of fundamental rights and guarantees or acts detrimental to the common interest, such as inadequate working conditions and negative impacts on local communities. Management prioritizes the protection of human rights and the promotion of social welfare. • Environmental: events related to degradation of the environment, biodiversity and overuse of natural resources such as deforestation, pollution and depletion of water resources. The approach seeks environmental conservation, sustainable use of resources and promotion of ecological practices. • Climate: comprises (i) the transition to a low-carbon economy, aimed at reducing or offsetting greenhouse gas emissions and preserving natural mechanisms for capturing these gases, and (ii) adaptation to extreme climate events and long-term environmental changes, such as severe storms, prolonged droughts and sea level rise. Based on these definitions, clients are classified in a socio and environmental risk scale ranging from Low to Very High. This rating is used for possible penalties in the rating.

Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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. As a supplement to the credit risk mitigation policy, ITAÚ UNIBANCO HOLDING CONSOLIDATED carries out specific analyses on ESG (Environmental, Social and Governance) requirements for operations guaranteed by rural and urban properties for each type of guarantee. For rural guarantees, reports with detailed social and environmental criteria are considered, including verification of compliance of the property with environmental legislation, status of the Rural Environmental Registry, existence of environmental liabilities, overlaps with protected areas, indigenous and quilombolas territories, settlements, archaeological sites, mining areas, and also analysis of land use and environmental history. The report also includes information on geo-referencing, land tenure regularization and climate risk indicators, strengthening commitment to sustainable practices and the mitigation of social and environmental risks. For urban guarantees, the evaluation report includes technical inspection and survey of indications of contamination, analysis of the surrounding areas as to the existence of potentially polluting activities (plants, gas stations, workshops, waste deposits, among others), in addition to checking official public lists of contaminated areas. The urban environmental report also considers the current and past use of the property, available infrastructure, and market diagnosis, ensuring that the property does not pose relevant environmental risks and is in compliance with the urbanistic and environmental standards in force. This process strengthen the commitment of ITAÚ UNIBANCO HOLDING CONSOLIDATED to adopting responsible practices aligned with ESG principles, thus contributing to the sustainability of operations and mitigation of credit risks associated with environmental and social factors. 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. 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. 137
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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. I.IV - Maximum exposure of financial assets to credit risk 03/31/2026 12/31/2025 Financial assets 2,638,106 2,569,058 Interbank investments 357,134 340,388 Securities purchased under agreements to resell 292,779 269,780 Interbank deposits 57,691 65,544 Assets guaranteeing technical provisions 6,689 5,093 (Provision for expected credit loss) (25) (29) Securities 968,035 925,416 Own portfolio 283,972 355,614 Restricted 321,511 215,242 Assets guaranteeing technical provisions 363,252 355,296 (Provision for expected credit loss) (700) (736) Derivatives 93,624 73,311 Operations with credit granting characteristics 1,219,313 1,229,943 Loan, lease and other credit operations 1,071,165 1,084,014 Securities 199,198 197,424 (Provision for expected credit loss) (51,050) (51,495) Interbank and interbranch accounts 296,771 282,008 Other financial assets 76,439 61,614 Off-balance sheet 727,078 715,869 Financial guarantees 132,871 134,105 Credit commitments and credits to be released 594,207 581,764 Total 3,738,394 3,628,549 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 (130 at 12/31/2025) Homogeneous groups: 87 in Stage 1 (86 at 12/31/2025), 28 in Stage 2 (29 at 12/31/2025) and 15 in Stage 3 (15 at 12/31/2025). The average risk concentration of credit operations for homogeneous groups is 0.8% (0.8% at 12/31/2025). 138
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 The breakdown of the gross book value of Operations with credit granting characteristics by maturity is shown below: 03/31/2026 12/31/2025 Overdue as from 1 day 25,790 24,241 Current up to 3 months 289,460 279,902 Current from 3 to 12 months 266,616 284,732 Current over 1 year 688,497 692,563 Total 1,270,363 1,281,438 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. 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. 4,557/17, and BCB Resolution No. 111/21, 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: 139
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 • 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. 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 of a portfolio overtime, which can be estimated from past behavior of returns of market risk factors for this 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. In addition, 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) 03/31/2026 12/31/2025 Average Minimum Maximum Total VaR Average Minimum Maximum Var Total VaR by risk factor group Interest rates 1,571 1,316 2,124 2,038 1,303 1,028 1,974 1,376 Currencies 50 31 99 52 40 22 97 51 Shares 44 38 55 45 45 36 89 46 Commodities 36 17 49 48 30 10 67 40 Effect of diversification - - - (312) - - - (385) Total risk 1,288 1,076 1,871 1,871 1,085 777 1,744 1,128 1) VaR by risk factor group considers information from foreign units.

Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 II.ll - Sensitivity analysis (trading and banking portfolios) ITAÚ UNIBANCO HOLDING CONSOLIDATED carried out a sensitivity analysis assessed by market risk factors considered relevant, according to the scenarios below: Scenario I: Addition of 1 base point in fixed interest rates, currency coupon, inflation and interest rate index, and 1 percentage point in currency and share prices. 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. Trading portfolio Exposures 03/31/2026 Risk factors Risk of variations in: Scenarios (1) I II III Fixed interest rate Fixed interest rates in reais 0.2 (167.7) (446.5) Currency coupon Foreign exchange coupon rates (0.3) (175.4) (337.1) Foreign currency Foreign exchange rates (5.3) (69.1) (274.1) Price indices Inflation coupon rates (1.3) (217.5) (444.0) TR TR coupon rates - - - Shares Share prices (0.6) 215.3 516.7 Other Exposures that do not fall under the definitions above 3.0 (26.8) 14.6 Total (4.3) (441.2) (970.4) 1) Amounts net of tax effects.

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. 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. 141
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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 long- term 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. As well as for LCR, when the NSFR is above the 100% threshold, the stable funds available are sufficient to support the stable funds required in the long term. Funding in accordance with maturities are presented below: 03/31/2026 12/31/2025 Current Non-current Current Non-current Other debt instruments 115,121 304,773 108,419 307,211 Funds from issues 103,912 168,487 96,925 168,561 Financial bills 29,369 30,379 28,359 32,802 Real estate credit bills 26,822 51,749 30,005 41,116 Rural credit bills 28,913 34,235 29,641 35,003 Guaranteed real estate bills 18,808 47,857 8,920 55,518 Debentures - 4,267 - 4,122 Foreign loans through securities 9,211 63,238 8,736 67,684 Brazil risk note programme 520 11,838 423 12,748 Structure note issued 2,203 7,075 2,789 7,630 Bonds 5,762 28,843 5,067 35,215 Fixed rate notes - 8,740 - 9,300 Eurobonds 38 17 56 23 Other 688 6,725 401 2,768 Funding from structured operations certificates 1,998 24,624 2,758 22,819 Debt instruments with subordination clauses - 48,424 - 48,147 Financial bills - 41,565 - 37,900 Euronotes - - - 2,755 Bonds - 6,859 - 7,492 Borrowing and onlending 108,205 28,711 118,637 28,527 Borrowing 93,975 11,830 104,328 12,168 Onlending - in Brazil – Official institutions 14,230 16,881 14,309 16,359 Total 223,326 333,484 227,056 335,738 In the period, ITAÚ UNIBANCO HOLDING CONSOLIDATED holds R$ 175,704 (R$ 167,275 at 12/31/2025) in Central Bank of Brazil depoits comprised in the heading Interbank and interbranch accounts in the Balance Sheet. The "Pillar 3", which details the Liquidity Ratios, can be viewed on the website www.itau.com.br/relacoes-com- investidores/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. 142
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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 No. 4,557/17, 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. 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. 143
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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, may impact the longevity of our businesses, the resilience of our assets and the generation of value in the short, medium and long terms. 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, in line with applicable corporate policies. 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 Climate (SEC) Risks, the first line areas, represented by businesses, carry out risk management in their daily activities, following the guidelines of the SEC Risk Policy and specific processes, counting on expert assessment of dedicated technical groups such as the Credit team. In addition, business support areas such as Sustainability and Institutional Legal also have specialized teams, which work in an integrated way in the management of all dimensions of Social, Environmental and Climate Risks linked to the conglomerate’s activities. The second-line areas, such as SEC Risks and Internal Controls provide support and ensure adequate governance of business and credit activities. In the third line, the Internal Audit works independently, carrying out assessments of risk management, controls and governance. The institution has specific procedures for managing SEC risks in its own operation (equity, branch infrastructure, technology and suppliers), in traditional risks such as credit, investments and key controlled entities. These procedures have been developed and implemented based on the principles of relevance and proportionality and include from the checking of information in public databases applicable to clients and suppliers to the detailed individualized analysis for certain clients, depending on the segment or type of product. 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. Considering the relevance of climate risk, ITAÚ UNIBANCO HOLDING CONSOLIDATED supports the Task Force on Climate-related Financial Disclosures (TCFD) and it is committed to maintaining a process of evolution and continuous improvement in line with your recommendations. In addition, the institution measures the sensitivity of its credit portfolio to climate risks by applying the Climate Risk Sensitivity Rule, which categorizes clients and sectors considering both physical risks (resulting from changes in weather patterns, such as increased rainfall, temperature, and extreme weather events) and the transition ones (resulting from changes in the economy, as a result of climate actions such as carbon pricing, climate regulation, market risks and reputation risks). 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. 144
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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 2025 – 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. 03/31/2026 12/31/2025 Available capital (amounts) Common equity tier 1 (CET 1) 186,771 185,595 Tier 1 209,183 208,161 Total capital (PR) 230,527 228,589 Risk-weighted assets (amounts) Total risk-weighted assets (RWA) 1,560,810 1,505,475 Risk-based capital ratios as a percentage of RWA Common equity tier 1 ratio (%) 12.0% 12.3% Tier 1 ratio (%) 13.4% 13.8% Total capital ratio (%) 14.8% 15.2% Additional CET1 buffer requirements as a percentage of RWA Capital conservation buffer requirement (%) 2.5% 2.5% Countercyclical buffer requirement (%) 0.1% 0.1% Bank G-SIB and/or D-SIB additional requirements (%) 1.0% 1.0% Total of bank CET1 specific buffer requirements (%) 3.6% 3.6% At 03/31/2026, the amount of perpetual subordinated debt that makes up Tier I capital is R$ 21,456 (R$ 21,543 at 12/31/2025) and the amount of subordinated debt that makes up Tier II capital is R$ 20,072 (R$ 19,034 at 12/31/2025). The Basel Ratio reached 14.8% at 03/31/2026, a decrease of 0.4 p.p. compared to 12/31/2025, mainly due to repurchases of debts that composing the Tier I and Tier II capital. The variation reflects mainly the implementation of regulatory changes related to credit and operating risks, growth in risk-weighted assets and payment of interest on own capital, effects partially offset by income for the period. Additionally, ITAÚ UNIBANCO HOLDING CONSOLIDATED has a surplus over the required minimum Total Capital of R$ 105,663 (R$ 108,151 at 12/31/2025), well above the Capital Buffer requirement of R$ 55,524 (R$ 53,686 at 12/31/2025), 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 03/31/2026, fixed assets ratio reached 20.7% (19.4% at 12/31/2025), showing a surplus of R$ 67,456 (R$ 69,887 at 12/31/2025).

Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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. • RWAOPAD = portion related to the operational risk capital requirement, calculated using standardized approach. RWA 03/31/2026 12/31/2025 Credit risk (excluding counterparty credit risk) 1,189,707 1,199,103 Of which: standardized approach for credit risk 1,111,021 1,119,760 Of which: foundation internal rating-based approach (F-IRB) - - Of which: advanced internal rating-based approach (A-IRB) 78,686 79,343 Counterparty credit risk (CCR) 34,875 29,789 Of which: standardized approach for counterparty credit risk (SA-CCR) 25,533 20,340 Of which: other CCR 9,342 9,449 Equity investments in funds - look-through approach 4,304 6,433 Equity investments in funds - mandate-based approach - - Equity investments in funds - fall-back approach 1,415 1,109 Securitization exposures in banking book 13,497 12,838 Market Risk 68,398 50,248 Of which: standardized approach (RWAMPAD) 83,598 61,438 Of which: internal models approach (RWAMINT) 36,516 30,685 Operational Risk 181,754 143,006 Payment services risk (RWASP) NA NA Amounts below the thresholds for deduction 66,860 62,949 Total 1,560,810 1,505,475 III - Recovery plan In response to the latest international crises, the Central Bank published CMN Resolution No. 5,187/24, 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 No. 4,557/17. 146
Itaú Unibanco Holding S.A. – Parent Company and Consolidated Condensed Financial Statements – March 31, 2026 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. 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 non- risk-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: 03/31/2026 12/31/2025 Permanent foreign investments 110,650 107,907 Net balance of other assets and liabilities indexed to foreign currency, including derivatives (91,092) (80,861) Net foreign exchange position 19,558 27,046 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. 3,263/05, 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

IBS and CBS will gradually replace the following taxes: Social integration program tax (PIS/Pasep), Contribution to social security financing (COFINS), Services tax (ISS), Financial transactions - Insurance tax (IOF-Insurance), Goods and services movement tax (ICMS) and Industrial products tax (IPI). These taxes will be discontinued throughout the period of implementation of the Tax reform. The new system of consumption taxation is structured in three incidence regimes: General regime, Specific regime and Differentiated regime. Among the main advances of the new legislation are the adoption of full non-cumulation, credit throughout the entire consumption chain, rationalization of tax rates and the definition of the incidence base from the net price of taxes. Financial services fall under the Specific regime and will be subject to the incidence of IBS and CBS starting January 1, 2027, with an initial tax rate estimated at 10.85%, and a forecasted gradual increase until reaching 12.50% in 2033. Potential impacts arising from the implementation of the new tax system are being evaluated and should be completed by the effective date of the legislation. 148

Introduction We have reviewed the accompanying condensed balance sheet of Itaú Unibanco Holding S.A. ("Bank") as at March 31, 2026 and the related condensed statements of income, comprehensive income, changes in stockholders' equity and cash flows for the three-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 March 31, 2026 and the related condensed consolidated statements of income, comprehensive income, changes in stockholders' equity and cash flows for the three-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. 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. 150 PricewaterhouseCoopers Auditores Independentes Ltda.
