Miami Branch, which functional currency is the US Dollar. 2) Company merged by Itaú Unibanco Holding S.A. at 01/31/2025. 19 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 I.I - Business combinations When accounting for business combinations, ITAÚ UNIBANCO HOLDING 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 are presented in Brazilian Reais, which is its functional and presentation currency. For each subsidiary, associate and joint venture, ITAÚ UNIBANCO HOLDING 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 Consolidated Statement of Income. For conversion of the Financial Statements of foreign entities with a functional currency other than Reais, ITAÚ UNIBANCO HOLDING 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 loses control of the foreign entity. The ITAÚ UNIBANCO HOLDING 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, on the trading date, 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 concurrently with the use of the related allowance for expected credit loss. Subsequent recoveries are accounted for as revenue in as a counterpart to asset. • ITAÚ UNIBANCO HOLDING transfers substantially the risks and benefits of the financial asset. The main judgments exercised by ITAÚ UNIBANCO HOLDING 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. When the contractual cash flow of a financial asset is renegotiated or otherwise modified, ITAÚ UNIBANCO HOLDING estimates that the modification event has not caused write-off of the contract, the gross book value of 20 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 this financial asset is recalculated by comparing the original and renegotiated cash flows, and the effects of the modification are recognized in income. During the period, ITAÚ UNIBANCO HOLDING updated the estimates of expected credit loss and write-off of financial assets. This change in the estimate resulted in the reduction of the period for the write-off of financial assets, which up to 31 December 2024 was up to 24 months. The change in the accounting estimate generated an impact of R$ (2,756) (R$ (1,453) net of taxes), recognized in income in 2025. Financial liabilities are written off when extinguished, this is, when the obligation specified in the contract is released, canceled, expired, or substantially modified. ITAÚ UNIBANCO HOLDING considers that the obligation was substantially modified when the present value of cash flows under the new terms is at least 10% different from the present value of the cash flows remaining from the original obligation. IV.I Classification of financial assets Financial assets are classified and subsequently measured in the following categories: • Amortized cost: 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: 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: 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 (Solely Payment of Principal and Interest Test – SPPI Test). Financial assets designated as fair value through profit or loss: ITAÚ UNIBANCO HOLDING has financial assets designated at fair value through profit or loss to reduce an accounting mismatch. 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. SPPI Test: is the assessment of cash flows generated by a financial instrument are assessed for the purpose of checking whether they represent solely payments of principal and interest (consideration for the time value of money, credit risk and profit margin). ITAÚ UNIBANCO HOLDING assesses mainly the following situations to determine compliance with the SPPI Test: 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 do not meet the SPPI Test and it's classified in the category Fair value through profit or loss. Hybrid Contracts: to identify if a contract contains embedded derivatives, ITAÚ UNIBANCO HOLDING 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; the underlying instrument is not booked at Fair value through profit or loss. 21 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 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 designates it, on an irrevocable basis, at Fair value through other comprehensive income. IV.II - Classification of financial liabilities Financial liabilities are subsequently measured at amortized cost, except for: • Financial liabilities at fair value through profit or loss: classification applied to financial liabilities designated, irrevocably, at fair value through profit or loss for the purpose to reduce accounting asymmetries and to derivatives. • Credit commitments and Credits to be released. • Financial guarantees: measured at the higher amount between (i) the provision for expected credit loss; and (ii) the balance of the fee on the service to be deferred in income, according to the contract term. • Premium bonds plans: they are classified as financial liabilities at the amortized cost, although they are regulated by the body that regulates the Brazilian insurance market. Revenue from premium bonds plans is recognized during the contract period and measured according to the contractual conditions of each plan. 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 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 adjustment to fair value of financial assets and liabilities is recognized in Stockholders' equity for financial assets measured at fair value through other comprehensive income or in the Consolidated Statement of Income for the other financial assets and liabilities. The portion of variation in the fair value of derivative financial liabilities and financial liabilities designated at fair value through profit or loss, resulting from changes in the own credit risk of ITAÚ UNIBANCO HOLDING is recognized in Income and in other comprehensive income, at the net amount of tax effects, respectively. 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 Interest and similar income and income of financial assets and liabilities at fair value through profit or loss. 22 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 For financial instruments measured at fair value on a recurring basis, including derivatives, that are not traded in active markets, the fair value is calculated by using valuation techniques based on assumptions, that consider market information and conditions. The estimated fair value obtained through these techniques cannot be substantiated by comparison with independent markets and, in many cases, cannot be realized on immediate settlement of the instrument. The main assumptions considered to estimate the fair value are: historical database, information on similar transactions, discount rate and estimate of future cash flows. The main judgments applied in the calculation of the fair value of more complex financial instruments, or those that are not negotiated in active markets or do not have liquidity, are: determining the model used with the selection of specific inputs and, in certain cases, evaluation adjustments are applied to the model amount or price quoted for financial instruments that are not actively traded. The application of these judgments may result in a fair value that is not indicative of the net realizable value or future fair values. However, ITAÚ UNIBANCO HOLDING 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 28. 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. Effective interest rate: ITAÚ UNIBANCO HOLDING uses the effective interest rate method to calculate interest income or expense for financial instruments at amortized cost, which considers costs and fees directly attributable to the contract, such as commissions paid or received by the parties to the contract, transaction costs and other premiums and discounts. ITAÚ UNIBANCO HOLDING classifies a loan as non-performing if the payment of the principal or interest has been overdue for 90 days or more. In this case, accrual of interest is no longer recognized. Expected credit loss: ITAÚ UNIBANCO HOLDING assesses the expected credit loss associated with financial assets measured at amortized cost and through other comprehensive income, credit commitments, credits to be released and financial guarantee contracts 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 financial instruments which are credit impaired, for which a probability of default (PD) of 100% is considered (problem assets). 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 credit loss amounts resulting from models and, according to its experience, makes adjustments that may result from certain clients’ credit status or temporary adjustments resulting from situations or new circumstances that have not been reflected in the modeling yet. The main assumptions considered to estimate the expected credit loss are: 23 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 • Determining criteria for significant increase or decrease in credit risk: ITAÚ UNIBANCO HOLDING determines triggers (indicators) of significant increase in the credit risk of a financial asset since its initial recognition on an individual or collective basis. For collective assessment purposes, financial assets are grouped based on characteristics of shared credit risk, considering the type of instrument, credit risk classifications, initial recognition date, remaining term, industry, among other significant factors. For wholesale business portfolios, the assessment is conducted on an individual basis, at the economic subgroup level. 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 for at least 6 months. • Maximum contractual period: ITAÚ UNIBANCO HOLDING 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 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 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. The main judgments exercised 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. IV.IV - Derivatives and use of hedge accouting Derivatives: all derivatives are measured at fair value through profit or loss and accounted for as financial assets when the fair value is positive and as financial liabilities when the fair value is negative. Accounting Hedge: the risk management conducted with derivatives and non-derivatives may give rise to accounting asymmetries due to the different methods to account for each instrument. In view of this, ITAÚ UNIBANCO HOLDING sometimes qualifies economic hedge operations as accounting hedge operations, changing the usual accounting of hedge items or hedging instruments, and, consequently, eliminating existing accounting asymmetry, in order to reflect the economic effects of hedge activity in the financial statements. ITAÚ UNIBANCO HOLDING continues applying all the hedge accounting requirements of IAS 39, that describes three types of hedges: cash flow hedge, hedge of net investment in foreign operations and fair value hedge, which are detailed in Note 7. At the beginning of a hedge transaction, the relationship between the hedging instruments and the hedged items, its risk management objective and strategy are documented. They can be designated as hedging instruments for accounting purposes, derivatives, financial and qualifiable financial assets and liabilities. To maintain the accounting hedge strategies, ITAÚ UNIBANCO HOLDING assesses the effectiveness of strategies on a continuous basis. In the event the hedge becomes ineffective, the designation is revoked, or the derivative expires or is sold, the accounting hedge should be prospectively discontinued. 24 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 The main judgments exercised in the assessment of hedge strategies are: identification of qualifiable assets and liabilities; determination of the risk to be hedged; selection of quantitative models for effectiveness assessment. • Cash flow hedge: the effective portion of gains or losses on hedging instrument is recognized directly in Other Comprehensive Income (hedge reserve). The ineffective portion or hedge components excluded from the assessment of effectiveness are recognized in income. To evaluate the effectiveness of the cash flow hedge, ITAÚ UNIBANCO HOLDING uses the hypothetical derivative method. At the time the corresponding income or expense of the hedged financial item affects income, the hedge reserve is reclassified to Income on Financial Assets and Liabilities at Fair Value through Profit or Loss. For non-financial hedged items, the hedge reserve is incorporated into the initial cost of the corresponding asset or liability. If the accounting hedge is discontinued, the hedge reserve will be reclassified to income at the time the expected transaction occurs or is no longer expected to occur. • Hedge of net investment in foreign operations: is accounted for in a manner similar to a cash flow hedge: the effective portion of hedge instrument gains or losses is recorded directly in Other Comprehensive Income (hedge reserve). The ineffective portion or hedge components excluded from the effectiveness analysis are recognized in income. To evaluate the effectiveness of the hedge of net investments in foreign operations, ITAÚ UNIBANCO HOLDING uses the dollar offset method. In the period the foreign operation is partially or completely disposed of, hedge is discontinued, and the hedge reserve is reclassified proportionally to income. • Fair value hedge: gains or losses arising from the measurement at fair value of the covered item, which correspond to the effective portion of the hedge, are recognized in income. If the accounting hedge is discontinued, any adjustment in the book value of the covered item should be amortized in income. To evaluate the effectiveness of the fair value hedge, ITAÚ UNIBANCO HOLDING uses the percentage approach and dollar offset method. 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 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. 25 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 VI - Investments in associates and joint ventures Associates are companies in which ITAÚ UNIBANCO HOLDING has a 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 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, 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 considers the non-cancellable period of the contract, the expectation of renewal, contractual termination, and the expected vacancy period, as the case may be. The main judgments exercised in lease operations are: determination of the discount rate that reflects the cost that would be incurred to buy the asset; establishment of low-value assets; and assessment of the expectation of contractual renewal. VIII - Fixed assets Fixed assets are booked at their acquisition cost less accumulated depreciation, and adjusted for impairment, if applicable. Depreciation is calculated under the straight-line method using rates based on the estimated useful lives of these assets. ITAÚ UNIBANCO HOLDING 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 lntangible 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, not being amortized. Intangible assets are immaterial goods acquired or internally developed, they include the Association for the promotion and offer of financial products and services, software, rights of use leases and rights for acquisition of payrolls. Intangible assets are measured at amortized cost after initial recognition and amortized using the straight-line method over their estimated useful lives. X - Impairment of non-financial assets The recoverable amount of investments in associates and joint ventures, right-of-use assets, fixed assets, goodwill and intangible assets is assessed semiannually or when there is an indication of loss. The assessment is conducted individually by asset class whenever possible or by cash-generating unit (CGU). 26 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 To assess the recoverable amount, ITAÚ UNIBANCO HOLDING 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 contracts and private pension To measure the groups of insurance contracts and private pension, ITAÚ UNIBANCO HOLDING uses the three measurement approaches below, considering the characteristics of the contracts: • Standard Model (Building Block Approach - BBA): insurance contracts without direct participation feature with coverage longer than 1 year or that are onerous. The Insurance portfolio basically includes Life, Health, Credit Life and Housing, the first two of which are onerous. The Private Pension portfolio includes Traditional Plans and Death and Disability Risk Coverage Plans, the former being onerous. Insurance contracts and private pension classified as onerous are not actively sold, and the contractual conditions of the life insurance contracts in force are different and classified as profitable. • Variable Fee Approach (VFA): applicable to insurance contracts with direct participation features are insurance contracts that are substantially investment-related service contracts under which an entity promises an investment return based on underlying items. ITAÚ UNIBANCO HOLDING applies this approach to the Free Benefit Generating Plan (PGBL) and Free Benefit Generating Life Plan (VGBL) private pension plans, whose contributions are remunerated at the fair value of the investment fund specially organized in which funds are invested and the insured party has the possibility of earning income after the accumulation period. • Simplified Model (Premium Allocation Approach - PAA): insurance contracts and reinsurance contracts held, whose coverage periods are equal to or less than one year or when they produce results similar to those that would be obtained if the standard model were used, comprising mainly: Personal Accidents and Protected Card. As these are short-term contracts, Liability for Remaining Coverage are not discounted at present value. However, the cash flows of Liability for Incurred Claims are discounted at present value and adjusted to reflect non-financial risks, since they have payments that are made one year after a claim occurs. The initial recognition of groups of insurance contracts and private pension is performed by the total of: • Contractual service margin, which represents the unearned profit that will be recognized as it provides insurance contract service in the future. • Fulfillment cash flows, composed of the present value of estimated cash inflows and outflows of funds over the period covered by the portfolio, risk adjusted for non-financial risk. The risk adjustment for non-financial risk is the compensation that the entity requires for bearing the uncertainty about the amount and timing of the cash flows that arises from non-financial risk. The Assets and Liabilities of insurance contracts and private pension are subsequently segregated between: • Asset or Liability for Remaining Coverage: represented by the fulfillment cash flows related to future services and the contractual service margin. The appropriation of the contractual service margin and losses (or reversals) in onerous contracts are recognized in the Income from Insurance Contracts and Private Pension, net of Reinsurance. In the Private Pension PGBL and VGBL portfolios, the contractual service margin is recognized according to the 27 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 provision of the management service and insurance risks, and in the other portfolios, recognition is on a straightline basis over the term of the contract. • Asset or Liability for Incurred Claims: represented by the fulfillment cash flows referring to services already provided, that are, amounts pending financial settlement related to claims and other expenses incurred. Changes in the fulfillment cash flows, including those arising from an increase in the amount recognized due to claims and expenses incurred in the period, are recognized in the Income from Insurance Contracts and Private Pension, net of Reinsurance. To estimate fulfillment cash flows and expected profitability (contractual service margin), ITAÚ UNIBANCO HOLDING uses actuarial models and assumptions, exercising judgment mainly to establish: (i) the aggregation of contracts; (ii) the period of service provided; (iii) discount rate; (iv) actuarial calculation models; (v) risk adjustment for non-financial risk models and confidence levels; (vi) the group's level of profitability; and (vii) contract coverage unit. The main assumptions used are: (i) inflow assumptions: contributions and premiums; (ii) outflow assumptions: conversion rates into income, redemptions, cancellation rate and loss ratio; (iii) discount rate; (iv) biometric tables; and (v) risk adjustment for non-financial risk. Regarding the assessment components separation of an insurance contract, the investment component that exists in ITAÚ UNIBANCO HOLDING’s private pension contracts of is highly interrelated with the insurance component, that is, the investment component (accumulation phase) is necessary to measure the payments to be made to the insured party (benefit granting phase). For portfolios of long-term insurance contracts and private pension, except for Private Pension PGBL and VGBL portfolios, ITAÚ UNIBANCO HOLDING opted for recognizing changes in discount rates in Other Comprehensive Income, that is, the Financial Income from Insurance Contracts and Private Pension will be segregated between Other Comprehensive Income and income for the period. In the portfolios of short-term insurance and Private Pension PGBL and VGBL, the financial income is fully recognized in income for the period. The assumptions used in the measurement of insurance contracts and private pension are reviewed periodically and are based on best practices and analysis of the experience of ITAÚ UNIBANCO HOLDING. The discount rate used by ITAÚ UNIBANCO HOLDING to bring the projected cash flows from insurance contracts and private pension to present value is obtained by building a Term Structure of Interest Rates with internal modeling, which represents a set of vertices that contain the expectation of an interest rate associated with the term of portfolio (or maturity). In addition to considering the characteristics of the indexing units of each portfolio (IGPM, IPCA and TR), the discount rate has a component that aims at reflecting the differences between the liquidity characteristics of the financial instruments that substantiate the rates observed in the market and the liquidity characteristics of insurance contracts (a “bottom-up” approach). Specifically for insurance products, cash flows are projected using the method known as the run-off triangle on a quarterly basis. For private pension plans, cash flows are projected based on assumptions applicable to the product. Risk adjustment for non-financial risk is obtained by resampling based on claims data with portfolio by grouping, using the Monte Carlo statistical method. Resampling is brought to present value using the discount rate applied to future cash flows. Based on this, percentiles proportional to the confidence level are calculated, determined in an interval between 60% and 70%, depending on the group. Biometric tables represent the probability of death, survival or disability of an insured party. For death and survival estimates, the latest Brazilian Market Insurer Experience tables (BR-EMS) are used, adjusted by the criterion of development of longevity expectations of the G Scale, and for the estimates of entry into disability, the Álvaro Vindas table is used. The conversion rate into income reflects the historical expectation of converting the balances accumulated by insured parties into retirement benefits, and the decision is influenced by behavioral, economic and tax factors. 28 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 XII - Provisions, contingent assets and contingent liabilities Provisions and contingent liabilities are assessed based on the Management’s best estimates considering the opinion of legal advisors. The accounting treatment of provisions and contingent liabilities depends on the likelihood of disbursing funds to settle obligations. According to the probability of loss they are classified as: (i) probable and are provisioned in the Financial Statements; (ii) possible, are not provisioned and are reported in the Notes; and (iii) remote: no provision is recognized, and contingent liabilities are not disclosed in the Financial Statements. Provisions and contingent liabilities are estimated in a mass or individualized basis: • Mass lawsuits: civil lawsuits and labor claims with similar characteristics, whose individual amounts are not relevant. The expected amount of the loss is estimated on a monthly basis, according to the statistical model. Civil and labor provision and contingencies are adjusted to the amount of the performance guarantee deposit when it is made. For civil lawsuits, their nature, and characteristics of the court in which they are being processed (Small claims court or ordinary court) is observed. For labor claims, the estimated amount is reassessed considering the court decisions rendered. • Individual lawsuits: civil lawsuits, labor claims, tax claims and social security lawsuits with peculiar characteristics or relevant amounts. For civil lawsuits and labor claims, the expected amount of the loss is periodically estimated, as the case may be, based on the determination of the amount claimed and the particularities of the lawsuits. The likelihood of loss is assessed according to the characteristics of facts and points of law regarding that lawsuit. Tax and social security lawsuits are assessed individually and are accounted for at the amount due. Assets pledged as guarantees of civil lawsuits, labor claims, tax claims and social security lawsuits should be conducted in court and are retained until a definitive court decision is made. Cash deposits, surety insurance, sureties and government securities are offered, and in case of unfavorable decision, the amount is paid to the counterparty. The amount of judicial deposits is updated in accordance with the regulations in force. Civil, labor, tax, and social security provisions, guaranteed by indemnity clauses in privatization and other procedures, in which there is liquidity, are recognized upon judicial notice, simultaneously with amounts receivable, not having effect on income. The main judgments exercised in the measurement of provisions and contingencies are: assessment of the probability of loss; aggregation of mass lawsuits; selection of the statistical model for loss assessment; and estimated provisions amount. Information on provisions and contingencies for legal proceedings are detailed in Note 29. 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. 29 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 The main judgments that ITAÚ UNIBANCO HOLDING 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. ITAÚ UNIBANCO HOLDING applies the normative exception and does not recognize and disclose deferred tax assets and liabilities related to taxes on profits under Pillar II of the Organization for Economic Cooperation and Development (OECD). Currently no material impacts on current tax are expected in the jurisdictions applicable to ITAÚ UNIBANCO HOLDING. The income tax and social contribution expense is recognized in the Statement of Income under Income Tax and Social Contribution, except when it refers to items directly recognized in Other Comprehensive Income, which will be recognized in income upon realization of the gain/loss on the instruments. Changes in tax legislation and rates are recognized in the period in which they are enacted. In cases where tax treatment of a tax is uncertain, ITAÚ UNIBANCO HOLDING assesses the need for recognizing a provision to cover this uncertainty. XIV - Post-employment benefits ITAÚ UNIBANCO HOLDING sponsors post-employment benefit plans for employees in Defined Benefit, Defined Contribution and Variable Contribution modalities. The present value of obligations, net of fair value of assets, is recognized in the actuarial liabilities according to the characteristics of the plan and actuarial estimates. When the fair value of the plan assets exceeds the present value of obligations, an asset is recognized, limited to the rights of ITAÚ UNIBANCO HOLDING. Actuarial estimates are based on assumptions of the following nature: (i) demographic: mainly the mortality table; and (ii) financial: the most relevant ones are the projection of inflation and the discount rate used to determine the present value of the obligations that considers the yields of government securities and the maturity of respective obligations. Annual remeasurements of the plans are recognized under Stockholders’ Equity, in other Comprehensive Income. The main judgments exercised in calculating the obligation of post-employment benefit plans are: selection of the mortality table and the discount rate. XV - Share-based payments Share-based payments are measured at the fair value, with recognition in Stockholders’ Equity during the vesting period of the instruments. In case the manager or employee leaves before the end of the vesting period, ITAÚ UNIBANCO HOLDING exercises judgment on the departure conditions, considering the specificity of each plan. The plans are settled with shares and are made up of variable compensation programs in shares and partner program. XVI - Treasury shares The purchase and sale of common and preferred shares are recorded in Stockholders’ Equity under Treasury shares at average share price. The difference between the sale price and the average price of the treasury shares is accounted for as a reduction or increase in Capital Reserves. The cancellation of treasury shares is conducted at the average price of shares and its effect is accounted for in Capital Reserves. 30 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 XVII - Capital compensation ITAÚ UNIBANCO HOLDING compensates its shareholders with dividends and Interest on Capital. Interest on capital is treated for accounting purposes as a dividend, and it is presented as a reduction of Stockholders' Equity in the Consolidated Financial Statements. Dividends are calculated and paid on the basis of the financial statements prepared under Brazilian accounting standards. Minimum dividend amounts ascertained based on percentages established in the bylaws are recorded as liabilities. Any other amount above the mandatory minimum dividend is accounted for as a liability when approved by of the Board of Directors. Dividends and interest on capital are presented in Note 19. XVIII - Commissions and banking fees Commissions and banking fees are recognized when ITAÚ UNIBANCO HOLDING provides or offers services to customers, in an amount that reflects the consideration ITAÚ UNIBANCO HOLDING expects to collect in exchange for those services. Incremental costs, when material, are recognized in assets and appropriated in income according to the expected term of the contract. Service revenues related to credit cards, debit, current account, payments and collections and economic, financial and brokerage advisory are recognized when said services are provided. Revenue from certain services, such as fees from funds management, collection and custody, are recognized over the life of the respective agreements, as services are provided. ITAÚ UNIBANCO HOLDING exercises judgment to identify whether the performance obligation is satisfied over the life of the contract or at the time the service is provided. Note 3 - Business development Zup I.T. Serviços em Tecnologia e Inovação S.A. On October 31, 2019, ITAÚ UNIBANCO HOLDING, through its subsidiary Redecard Instituição de Pagamento S.A. (REDE), entered into a purchase and sale agreement for 100% of Zup I.T. Serviços em Tecnologia e Inovação S.A.'s (ZUP) capital in three phases, and the first phase, performed in March 2020, granted control to ITAÚ UNIBANCO HOLDING. In 2023, ITAÚ UNIBANCO HOLDING increased its ownership interest by 20.57% (2,228,342 shares) for the amount of R$ 199, then holding 72.51%.

The nominal value of these contracts represents the face value of the associated instrument. Forwards - They are forward contracts that involve the purchase or sale of financial and non-financial instruments on a future date, at a contracted price, and which are settled by delivering or not the underlying item against a financial amount. They include exchange contracts that are currency forwards. Options - They are contracts that allow the buyer, upon the payment of a fee, the right to buy or sell financial or non-financial instruments at a fixed price during a specified term. Swaps - They are contracts to settle in cash on a future date or dates, the difference between two specified financial indexes, applied over a reference principal amount.

Derivatives and repurchased agreements not set off in the balance sheet relate to transactions in which there are enforceable master netting agreements or similar agreements, but the offset criteria have not been met in accordance with paragraph 42 of IAS 32 mainly because ITAÚ UNIBANCO HOLDING has no intention to settle on a net basis, or realize the asset and settle the liability simultaneously. 37 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 Note 7 - Hedge accounting The accounting policy on Hedge accounting is presented in Note 2c IV. ITAÚ UNIBANCO HOLDING 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 32. To protect cash flows and fair value of instruments designated as hedged items, derivatives and financial assets are used. ITAÚ UNIBANCO HOLDING manages risks through the economic relationship between hedging instruments and hedged items, where the expectation is that these instruments will move in opposite directions and in the same proportion, with the purpose of neutralizing risk factors. For portfolio strategies, the coverage ratio is often re-established as both the protected item and instruments change over time, reflecting risk management guidelines approved by management. The designated coverage ratio is always 100% of the risk factor eligible for coverage. Sources of ineffectiveness are in general related to the counterparty’s credit risk and possible mismatches of terms between the hedging instrument and the hedged item. 38 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 a) Summaries by instrument and hedge item, nominal amount and maturity 09/30/2025 12/31/2024 Hedge instruments Hedged item Hedge instruments Hedged item Notional amount Fair value adjustment Gross book value Notional amount Fair value adjustment Gross book value Cash flow hedge 177,757 (257) 177,824 236,045 (91) 242,931 Hedge of assets transactions 2,526 - 2,509 1,966 (10) 2,420 Hedge of asset-backed securities under repurchase agreements 12,077 - 12,444 63,261 (123) 66,795 Hedge of assets denominated in Chilean unit of account 55,492 (224) 55,492 39,894 (159) 39,842 Hedge of loan operations 20,209 26 20,209 10,910 54 10,955 Hedge of deposits and repurchase agreements 53,437 - 53,218 107,677 76 110,405 Hedge of funding 32,913 (61) 32,914 10,900 82 10,908 Hedge of highly probable forecast transactions 1,103 2 1,038 1,437 (11) 1,606 Hedge of net investment in foreign operations 26,351 (60) 25,666 19,363 4,572 23,701 Hedge of net investment in foreign operations 26,351 (60) 25,666 19,363 4,572 23,701 Fair value hedge 129,314 (1,004) 130,982 101,443 837 101,020 Hedge of securities at amortized cost 45,648 (891) 48,074 2,186 (49) 2,186 Hedge of securities at fair value through other comprehensive income 21,305 43 20,584 36,557 847 36,341 Hedge of loan operations 29,644 (132) 29,644 37,116 333 37,116 Hedge of funding 32,659 (24) 32,618 25,287 (294) 25,287 Hedge of firm commitments 58 - 62 297 - 90 Total 333,422 (1,321) 334,472 356,851 5,318 367,652 39 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 09/30/2025 0-1 year 1-2 years 2-3 years 3-4 years 4-5 years 5-10 years Over 10 years Total Cash flow hedge 102,573 31,574 16,326 8,580 12,879 5,825 - 177,757 Hedge of assets transactions - - 2,001 - 525 - - 2,526 Hedge of asset-backed securities under repurchase agreements - - 7,863 4,214 - - - 12,077 Hedge assets denominated in Chilean unit of account 52,303 3,189 - - - - - 55,492 Hedge of loan operations 9,509 3,900 727 1,106 4,967 - - 20,209 Hedge of deposits and repurchase agreements 25,394 14,567 3,081 2,747 1,972 5,676 - 53,437 Hedge of funding 14,265 9,917 2,654 513 5,415 149 - 32,913 Hedge of highly probable forecast transactions 1,102 1 - - - - - 1,103 Hedge of net investment in foreign operations 26,351 - - - - - - 26,351 Hedge of net investment in foreign operations (1) 26,351 - - - - - - 26,351 Fair value hedge 56,079 18,814 22,249 10,500 5,563 13,225 2,884 129,314 Hedge of securities at amortized cost 8,261 6,002 12,513 3,888 3,265 10,363 1,356 45,648 Hedge of securities at fair value through other comprehensive income 16,700 125 2,865 261 214 216 924 21,305 Hedge of loan operations 12,700 5,906 4,330 4,522 402 1,486 298 29,644 Hedge of funding 18,360 6,781 2,541 1,829 1,682 1,160 306 32,659 Hedge of firm commitments 58 - - - - - - 58 Total 185,003 50,388 38,575 19,080 18,442 19,050 2,884 333,422 12/31/2024 0-1 year 1-2 years 2-3 years 3-4 years 4-5 years 5-10 years Over 10 years Total Cash flow hedge 125,198 68,069 28,155 8,754 4,980 889 - 236,045 Hedge of assets transactions - - 1,247 719 - - - 1,966 Hedge of asset-backed securities under repurchase agreements 22,629 15,489 17,016 5,170 2,957 - - 63,261 Hedge assets denominated in Chilean unit of account 16,801 23,093 - - - - - 39,894 Hedge of loan operations 7,310 1,148 746 1,272 434 - - 10,910 Hedge of deposits and repurchase agreements 67,617 27,835 9,146 1,467 1,174 438 - 107,677 Hedge of funding 9,404 504 - 126 415 451 - 10,900 Hedge of highly probable forecast transactions 1,437 - - - - - - 1,437 Hedge of net investment in foreign operations 19,363 - - - - - - 19,363 Hedge of net investment in foreign operations (1) 19,363 - - - - - - 19,363 Fair value hedge 33,722 24,659 10,366 10,274 9,987 10,226 2,209 101,443 Hedge of securities at amortized cost 1,091 1,095 - - - - - 2,186 Hedge of securities at fair value through other comprehensive income 11,165 7,544 3,741 4,384 2,965 5,251 1,507 36,557 Hedge of loan operations 8,227 12,446 6,090 4,334 4,092 1,647 280 37,116 Hedge of funding 12,942 3,574 535 1,556 2,930 3,328 422 25,287 Hedge of firm commitments 297 - - - - - - 297 Total 178,283 92,728 38,521 19,028 14,967 11,115 2,209 356,851 1) Classified as current, since instruments are frequently renewed. 40 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 b) Cash flow hedge Strategies are used to manage the variation: • In the cash flow of interest payment by using futures contracts: Hedge of asset transactions (DI);

There is a lockup period of from three to five years, counted from the initial investment date, and the shares are thus subject to market price variations. After complying with the preconditions outlined in the program, beneficiaries are entitled to receive shares as consideration, in accordance with the number of shares indicated in the program internal regulations. The acquisition price of shares and share-based instruments is established every six months as the average of the share price over the last 30 days, which is performed on the seventh business day prior to the compensation grant date. The fair value of the consideration in shares is the market price at the grant date, less expected dividends.

Note 26 - Post-employment benefits The accounting policies on post-employment benefits are presented in Note 2c XIV. Retirement plans are managed by Closed-end Private Pension Entities (EFPC) and are closed to new applicants. These entities have an independent structure and manage their plans according to the characteristics of their regulations. There are three types of retirement plan: • 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. 76 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 a) Main actuarial assumptions The table below shows the actuarial assumptions of demographic and financial nature used to calculate the defined benefit obligation: Type Assumption 09/30/2025 09/30/2024 Demographic Mortality table AT-2000 softned by 10% AT-2000 softned by 10% Financial Discount rate (1) 11.59% p.a. 9.56% p.a. Financial Inflation (2) 4.00% p.a. 4.00% p.a. 1) Considers the interest rates of the National Treasury Notes (NTN-B) with maturity dates near the terms of the respective obligations, compatible with the economic scenario observed on the balance sheet closing date, considering the volatility of interest market and models used. 2) Long-term inflation projected by the market, according to the maturity of each plan. Retirement plans sponsored by foreign subsidiaries - Banco Itaú (Suisse) S.A., Itaú Colombia S.A. and PROSERV - Promociones y Servicios S.A. de C.V. - are structured as Defined Benefit modality and adopt actuarial assumptions adequate to masses of participants and the economic scenario of each country. b) Risk management The EFPCs sponsored by ITAÚ UNIBANCO HOLDING are regulated by the National Council for Complementary Pension (CNPC) and PREVIC, and have an Executive Board, Advisory and Tax Councils. 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 is calculated by adopting a discount, 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 increase 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 are not adherent to 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 use 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. 77 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 c) Asset management The purpose of the management of funds is the long-term balance between pension assets and liabilities with payment of benefits by exceeding actuarial goals(discount rate plus benefit adjustment index, established in the plan regulations). Below is a table with the allocation of assets by category, segmented into Quoted in an active market and Not quoted in an active market: Types Fair value % Allocation 09/30/2025 12/31/2024 09/30/2025 12/31/2024 Fixed income securities 21,277 20,732 96.4% 96.5% Quoted in an active market 20,627 20,117 93.5% 93.6% Non quoted in an active market 650 615 2.9% 2.9% Variable income securities 1 9 - - Quoted in an active market 1 4 - - Non quoted in an active market - 5 - - Structured investments 129 120 0.6% 0.6% Non quoted in an active market 129 120 0.6% 0.6% Real estate 578 546 2.6% 2.5% Loans to participants 88 83 0.4% 0.4% Total 22,073 21,490 100.0% 100.0% The defined benefit plan assets include shares of ITAÚ UNIBANCO HOLDING, its main parent company (ITAÚSA) and of subsidiaries of the latter, with a fair value of R$ 1 (R$ 1 at 12/31/2024), and real estate rented to group companies, with a fair value of R$ 511 (R$ 472 at 12/31/2024). d) Other post-employment benefits ITAÚ UNIBANCO HOLDING and its subsidiaries do not have additional liabilities related to post-employment benefits, except in cases arising from maintenance commitments assumed in acquisition agreements which occurred over the years, as well as those benefits originated from court decision in the terms and conditions established, in which there is total or partial sponsorship of health care plans for a specific group of former employees and their beneficiaries. Its costing is actuarially determined so as to ensure coverage maintenance. These plans are closed to new applicants. Assumptions for discount rate, inflation, mortality table and actuarial method are the same as those used for retirement plans. ITAÚ UNIBANCO HOLDING used the percentage of 4% p.a. for medical inflation, additionally considering, inflation rate of 4% p.a. Particularly in other post-employment benefits, there is medical inflation risk associated with above expectation increases in medical costs. To mitigate this risk, the same financial risks mitigation strategies are used. 78 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 e) Change in the net amount recognized in the balance sheet The net amount recognized in the Balance Sheet is limited by the asset ceiling and it is computed based on estimated future contributions to be realized by the sponsor, so that it represents the maximum reduction amount in the contributions to be made. 09/30/2025 Note BD and CV plans CD plans Other postemployment benefits Total Net asset Actuarial liabilities Asset ceiling Recognized amount Pension plan fund Asset ceiling Recognized amount Liabilities Recognized amount Amounts at the beginning of the period 21,490 (19,035) (4,237) (1,782) 365 (81) 284 (562) (2,060) Amounts recognized in income (1+2+3+4) 1,788 (1,583) (364) (159) (9) (7) (16) (46) (221) 1 - Cost of current service - (18) - (18) - - - - (18) 2 - Cost of past service - - - - - - - - - 3 - Net interest 1,788 (1,565) (364) (141) 37 (7) 30 (46) (157) 4 - Other revenues and expenses (1) - - - - (46) - (46) - (46) Amount recognized in stockholders' equity - other comprehensive income (5+6+7) (4) 27 (30) (7) - - - - (7) 5 - Effects on asset ceiling - - (30) (30) - - - - (30) 6 - Remeasurements - 15 - 15 - - - - 15 Changes in demographic assumptions - - - - - - - - - Changes in financial assumptions - - - - - - - - - Experience of the plan (2) - 15 - 15 - - - - 15 7 - Exchange variation (4) 12 - 8 - - - - 8 Other (8+9+10) (1,201) 1,413 - 212 - - - 62 274 8 - Receipt by destination of resources - - - - - - - - - 9 - Benefits paid (1,413) 1,413 - - - - - 62 62 10 - Contributions and investments from sponsor 212 - - 212 - - - - 212 Amounts at the end of period 22,073 (19,178) (4,631) (1,736) 356 (88) 268 (546) (2,014) Amount recognized in Assets 18a 18 268 - 286 Amount recognized in Liabilities 18b (1,754) - (546) (2,300) 12/31/2024 BD and CV plans CD plans Other postemployment benefits Total Net assets Actuarial liabilities Asset ceiling Recognized amount Pension plan fund Asset ceiling Recognized amount Liabilities Recognized amount Amounts at the beginning of the period 23,754 (21,590) (4,130) (1,966) 393 (80) 313 (776) (2,429) Amounts recognized in income (1+2+3+4) 2,226 (2,015) (397) (186) 105 (7) 98 (65) (153) 1 - Cost of current service - (29) - (29) - - - - (29) 2 - Cost of past service - - - - - - - - - 3 - Net interest 2,226 (1,986) (397) (157) 41 (7) 34 (65) (188) 4 - Other revenues and expenses (1) - - - - 64 - 64 - 64 Amount recognized in stockholders' equity - other comprehensive income (5+6+7) (3,240) 2,762 290 (188) (133) 6 (127) 88 (227) 5 - Effects on asset ceiling - - 290 290 - 6 6 - 296 6 - Remeasurements (3,244) 2,790 - (454) (133) - (133) 88 (499) Changes in demographic assumptions - - - - - - - - - Changes in financial assumptions - 3,197 - 3,197 - - - 91 3,288 Experience of the plan (2) (3,244) (407) - (3,651) (133) - (133) (3) (3,787) 7 - Exchange variation 4 (28) - (24) - - - - (24) Other (8+9+10) (1,250) 1,808 - 558 - - - 191 749 8 - Receipt by destination of resources - - - - - - - - - 9 - Benefits paid (1,808) 1,808 - - - - - 191 191 10 - Contributions and investments from sponsor 558 - - 558 - - - - 558 Amounts at the end of period 21,490 (19,035) (4,237) (1,782) 365 (81) 284 (562) (2,060) Amount recognized in Assets 18a 17 284 - 301 Amount recognized in Liabilities 18b (1,799) - (562) (2,361) 1) Corresponds to the use of asset amounts allocated in pension funds of the defined contribution plans. 2) Correspond to the income obtained above / below the expected return and comprise the contributions made by participants. 79 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 Net interest correspond to the amount calculated on 01/01/2025 based on the initial amount (Net assets, Actuarial liabilities and Restriction of assets), deducting the estimated amount of payments/receipts of benefits/contributions, multiplied by the discount rate of 11.59% p.a. (On 01/01/2024 the rate used was 9.56% p.a.). ITAÚ UNIBANCO HOLDING sponsors a Plano BD. The amount recognized in Liabilities is R$ 55, in Other Comprehensive Income is R$ 8 and in income/(expense) is R$ (4). f) Defined benefit contributions Estimated contributions Contributions made 2025 01/01 to 09/30/2025 01/01 to 09/30/2024 Retirement plan - FIU 17 40 61 Retirement plan - FUNBEP 94 146 449 Total (1) 111 186 510 1) Include extraordinary contributions agreed upon in deficit equation plans. g) Maturity profile of defined benefit liabilities Duration (1) 2025 2026 2027 2028 2029 2030 to 2034 Pension plan - FIU 8.08 1,244 1,192 1,230 1,264 1,298 6,886 Pension plan - FUNBEP 7.60 716 733 750 767 782 4,084 Other post-employment benefits 7.29 85 91 72 45 47 258 Total 2,045 2,016 2,052 2,076 2,127 11,228 1) Average duration of plan´s actuarial liabilities. h) Sensitivity analysis To measure the effects of changes in the key assumptions, sensitivity tests are conducted in actuarial liabilities annually. The sensitivity analysis considers a vision of the impacts caused by changes in assumptions, which could affect the income for the period and stockholders’ equity at the balance sheet date. This type of analysis is usually carried out under the ceteris paribus condition, in which the sensitivity of a system is measured when only one variable of interest is changed and all the others remain unchanged. The results obtained are shown in the table below: Main assumptions BD and CV plans Other post-employment benefits Present value of liability Income Stockholders´ equity (Other comprehensive income) (1) Present value of liability Income Stockholders´ equity (Other comprehensive income) (1) Discount rate Increase by 0.5 p.p.

Insurance products sold by ITAÚ UNIBANCO HOLDING are divided into (i) non-life insurance, which guarantees loss, damage or liability for objects or people; and (ii) life insurance, which includes coverage against the risk of death and personal accidents. Insurance products are substantially offered through the electronic channels and branches of ITAÚ UNIBANCO HOLDING. ITAÚ UNIBANCO HOLDING reinsures the portion of the underwritten risks that exceed the maximum liability limits it deems to be appropriate for each segment and product. These reinsurance contracts allow the recovery of a portion of the losses with the reinsurer, although they do not release ITAÚ UNIBANCO HOLDING from the main obligation. 80 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 Private pension products are essentially divided into: (i) Free Benefit Generating Plan (PGBL) and Free Benefit Generating Life Plan (VGBL): whose main objective is to accumulate financial resources, the payment of which is made by means of income; and (ii) traditional: pension plan with a minimum guarantee of profitability, which is no longer sold. Financial assets related to insurance and private pension contracts are composed mainly of government securities measured at amortized cost and fair value through other comprehensive income, the latter being preferably related to the assets guaranteeing long-term obligations. Therefore, effects at present value of projected cash flows from insurance and private pension contracts are substantially neutralized by these FVOCI financial assets. The liquidity management of insurance and private pension contracts is detailed in Note 32.

Fair value The accounting policy on fair value of financial instruments is presented in Note 2c IV. a) Assets and liabilities measured at fair value The assets and liabilities measured at fair value on a recurring basis are classified as follows: Level 1: Securities and non-financial assets with liquid prices available in an active market and derivatives traded on stock exchanges. This classification level includes most of the Brazilian government securities, government securities from Latin America, government securities from other countries, shares, debentures with price published by Associação Brasileira das Entidades dos Mercados Financeiros e de Capitais (ANBIMA) and other traded in an active market. Level 2: Securities, derivatives and others that do not have price information available and are priced based on conventional or internal models. The inputs used by these models are captured directly or built from observations of active markets. Most of derivatives, certain Brazilian government bonds, debentures and other corporate securities whose credit component effect is not considered relevant, are at this level. Level 3: Securities and derivatives for which pricing inputs are generated by statistical and mathematical models. Debentures and other corporate securities that do not fit into level 2 rule and derivatives with maturities greater than the last observable vertices of the discount curves are at this level. 84 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 The following table presents the assets and liabilities measured at fair value on a recurring basis, segregated between levels of the fair value hierarchy. 09/30/2025 12/31/2024 Level 1 Level 2 Level 3 Fair value Level 1 Level 2 Level 3 Fair value Financial assets 607,928 133,627 413 741,968 535,394 128,576 2,158 666,128 Financial assets at fair value through other comprehensive income 125,071 4,797 237 130,105 103,319 2,766 218 106,303 Government securities 120,810 - - 120,810 98,873 - - 98,873 Brazil 74,595 - - 74,595 64,377 - - 64,377 Latin America 27,620 - - 27,620 21,470 - - 21,470 Abroad 18,595 - - 18,595 13,026 - - 13,026 Corporate securities 3,587 4,746 237 8,570 3,937 2,709 218 6,864 Rural product note - - - - - 126 - 126 Bank deposit certificates - 151 - 151 - 83 - 83 Real estate receivables certificates - 18 - 18 - 57 - 57 Debentures 1,678 850 237 2,765 761 519 218 1,498 Eurobonds and other 1,909 3,407 - 5,316 3,162 1,650 - 4,812 Financial credit bills - 5 - 5 - 53 - 53 Promissory and commercial notes - 40 - 40 - - - - Other - 275 - 275 14 221 - 235 Shares 674 51 - 725 509 57 - 566 Financial assets at fair value through profit or loss 482,857 128,830 176 611,863 432,075 125,810 1,940 559,825 Government securities 399,696 3,698 - 403,394 364,740 2,810 - 367,550 Brazil 393,513 3,698 - 397,211 358,886 2,810 - 361,696 Latin America 6,183 - - 6,183 4,381 - - 4,381 Abroad - - - - 1,473 - - 1,473 Corporate securities 71,655 72,883 61 144,599 58,396 69,062 1,834 129,292 Rural product note - 1,588 - 1,588 - 941 - 941 Bank deposit certificates - 1,185 - 1,185 - 450 - 450 Real estate receivables certificates 312 1,428 - 1,740 265 1,289 100 1,654 Debentures 70,457 27,509 61 98,027 55,942 29,466 1,734 87,142 Eurobonds and other 707 2,846 - 3,553 1,968 23 - 1,991 Financial bills - 35,500 - 35,500 - 33,071 - 33,071 Promissory and commercial notes - 896 - 896 - 1,216 - 1,216 Other 179 1,931 - 2,110 221 2,606 - 2,827 Shares 10,754 16,020 115 26,889 7,659 18,115 106 25,880 Investment funds 752 36,229 - 36,981 1,280 35,823 - 37,103 Designated as fair value through profit or loss 24,998 - - 24,998 318 - - 318 Government securities 24,998 - - 24,998 318 - - 318 Brazil 11,551 - - 11,551 43 - - 43 Latin America 12,819 - - 12,819 275 - - 275 Abroad 628 - - 628 - - - - Other financial assets - 2,708 - 2,708 - 1,612 - 1,612 Non-financial assets 3,079 - - 3,079 2,345 - - 2,345 Financial liabilities at fair value through profit or loss - (252) - (252) - (862) - (862) Financial assets at fair value through profit or loss - (252) - (252) - (862) - (862) Structured notes - (252) - (252) - (318) - (318) Other financial liabilities - - - - - (544) - (544) 85 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 The following table presents the breakdown of fair value hierarchy levels for derivative assets and liabilities. 09/30/2025 12/31/2024 Level 1 Level 2 Level 3 Fair value Level 1 Level 2 Level 3 Fair value Assets 213 80,610 213 81,036 5 92,062 372 92,439 Options - 19,233 10 19,243 - 21,139 31 21,170 Forward 211 12,880 17 13,108 - 1,721 18 1,739 Swaps - 39,190 186 39,376 - 55,106 322 55,428 NDF - 7,766 - 7,766 - 12,207 - 12,207 Credit derivatives - 635 - 635 - 632 1 633 Other 2 906 - 908 5 1,257 - 1,262 Liabilities (1,522) (76,489) (1,101) (79,112) (67) (85,171) (175) (85,413) Options (1) (17,187) (60) (17,248) - (20,580) (8) (20,588) Forward (1,476) (13,102) (15) (14,593) - (1,435) (15) (1,450) Swaps - (37,316) (1,026) (38,342) - (51,242) (152) (51,394) NDF (43) (8,313) - (8,356) - (10,761) - (10,761) Credit derivatives - (383) - (383) - (795) - (795) Other (2) (188) - (190) (67) (358) - (425) 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 data base. The most frequent cases of assets classified as Level 3 are justified by the discount factors used and corporate bonds whose credit component is relevant. Factors such as the fixed interest curve in Brazilian Reais and the TR coupon curve – and, as a result, their related factors – have inputs with terms shorter than the maturities of fixedincome assets. Changes in the fair value hierarchy In the periods, there were no material transfer between Level 1 and Level 2. The tables below show balance sheet changes for financial instruments classified by ITAÚ UNIBANCO HOLDING in Level 3 of the fair value hierarchy. Derivatives classified in Level 3 correspond to swaps and options. 86 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 Fair value at Total gains or losses (realized/unrealized) Purchases Settlements Transfers in the hierarchy Fair value at Total gains or losses (unrealized) 01/01/2025 12/31/2024 Income Other comprehensive income 09/30/2025 Financial assets 2,158 238 5 27 (1,648) (367) 413 (195) At fair value through other comprehensive income 218 32 5 6 (23) (1) 237 (1) Corporate securities 218 32 5 6 (23) (1) 237 (1) Debentures 218 32 5 - (17) (1) 237 (1) Financial bills - - - 6 (6) - - - At fair value through profit or loss 1,940 206 - 21 (1,625) (366) 176 (194) Corporate securities 1,940 206 - 21 (1,625) (366) 176 (194) Shares 106 4 - 5 - - 115 (102) Real estate receivables certificates 100 9 - 1 - (110) - - Debentures 1,734 193 - 3 (1,613) (256) 61 (92) Eurobonds and other - - - 12 (12) - - - Derivatives - assets 372 79 - 179 (134) (283) 213 (209) Forward 18 (2) - 1 - - 17 - Option 31 29 - 60 (110) - 10 (9) Swaps 322 52 - 118 (23) (283) 186 (200) Credit derivatives 1 - - - (1) - - - Derivatives - liabilities (175) (160) - (810) 96 (52) (1,101) 311 Forward (15) - - (15) 15 - (15) - Option (8) (11) - (58) 16 1 (60) (39) Swaps (152) (149) - (737) 65 (53) (1,026) 350 Fair value at Total gains or losses (realized/unrealized) Purchases Settlements Transfers in the hierarchy Fair value at Total gains or losses (unrealized) 01/01/2024 12/31/2023 Income Other comprehensive income 12/31/2024 Financial assets 2,371 298 6 1,713 (957) (1,273) 2,158 (994) At fair value through other comprehensive income 253 12 6 504 (372) (185) 218 - Corporate securities 253 12 6 504 (372) (185) 218 - Shares 193 - - - (193) - - - Debentures - 7 (1) 216 (144) 140 218 - Eurobonds and other 60 5 7 288 (35) (325) - - At fair value through profit or loss 2,118 286 - 1,209 (585) (1,088) 1,940 (994) Corporate securities 2,118 286 - 1,209 (585) (1,088) 1,940 (994) Shares 71 36 - 3 (4) - 106 (98) Real estate receivables certificates 126 (27) - 83 (95) 13 100 (78) Debentures 1,895 306 - 950 (259) (1,158) 1,734 (818) Promissory notes 17 - - - - (17) - - Eurobonds and other 5 (41) - 132 (87) (9) - - Financial bills 4 - - - (4) - - - Other - 12 - 41 (136) 83 - - Derivatives - assets 262 176 - 235 (216) (85) 372 270 Forward 19 (1) - - - - 18 - Option 6 13 - 67 (47) (8) 31 (2) Swaps 236 164 - 168 (169) (77) 322 271 Credit derivatives 1 - - - - - 1 1 Derivatives - liabilities (389) (215) - (306) 239 496 (175) 13 Forward (16) 1 - - - - (15) - Option (1) 17 - (54) 23 7 (8) 7 Swaps (372) (233) - (252) 216 489 (152) 6 87 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 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 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 share 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 measured at fair value on a non-recurring basis are: • Central Bank of Brazil deposits, Securities purchased under agreements to resell and Securities sold under repurchase agreements - The book value for these instruments is close to their fair values. 88 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 • Interbank deposits, Deposits, lnterbank market funds and lnstitutional market funds - They are 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. • Loan and lease operations - Fair value is estimated for groups of loans with similar financial and risk characteristics, using valuation models. The fair value of fixed-rate loans is determined by discounting estimated cash flows, at interest rates applicable to similar loans. For the majority of loans at floating rates, the book value is considered to be close to their fair value. The fair value of loan and lease operations not overdue is calculated by discounting the expected payments of principal and interest to maturity. The fair value of overdue loan and lease operations is based on the discount of estimated cash flows, using a rate proportional to the risk associated with the estimated cash flows, or on the underlying collateral. The assumptions for cash flows and discount rates rely on information available in the market and specific knowledge of the debtor. • Other financial assets / liabilities - Primarily composed for receivables from credit card issuers, deposits in guarantee for contingent liabilities, provisions and legal obligations and trading and intermediation of securities. The book value for these assets/liabilities substantially approximate to their fair values, since they principally represent amounts to be received in the short term from credit card holders and to be paid to credit card issuers, deposits demanded judicially (indexed to market rates) made by ITAÚ UNIBANCO HOLDING to secure lawsuits or very short-term receivables (generally with a maturity of approximately 5 business days). All of these items represent assets/liabilities without material market, credit or liquidity risks. Financial instruments not included in the Balance Sheet (Note 32) are represented by Letters of credit to be released and Financial guarantees, which amount to R$ 182,336 (R$ 196,845 at 12/31/2024) with an estimated fair value of R$ 149 (R$ 111 at 12/31/2024).

In the ordinary course of its business, ITAÚ UNIBANCO HOLDING 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’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 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. 89 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 ITAÚ UNIBANCO HOLDING, 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 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 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. Labor claims Provisions and contingencies arise from lawsuits in which labor rights provided for in labor legislation specific to the related profession are discussed, such as: overtime, salary equalization, reinstatement, transfer allowance, and pension plan supplement, among others. Other risks These are quantified and accrued on the basis of the amount of rural credit transactions with co-obligation and FCVS (salary variations compensation fund) credits assigned. 90 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 I - Civil, labor and other risks provisions Below are the changes in civil, labor and other risks provisions: 09/30/2025 Note Civil Labor Other Risks Total Opening balance - 01/01 3,207 8,213 1,066 12,486 (-) Provisions guaranteed by indemnity clause 2c XII (169) (671) - (840) Subtotal 3,038 7,542 1,066 11,646 Adjustment / Interest 23 92 432 - 524 Changes in the period reflected in income 23 912 2,638 93 3,643 Increase 1,320 2,950 379 4,649 Reversal (408) (312) (286) (1,006) Payment / Transfer (1,032) (2,306) (36) (3,374) Subtotal 3,010 8,306 1,123 12,439 (+) Provisions guaranteed by indemnity clause 2c XII 178 649 - 827 Closing balance 3,188 8,955 1,123 13,266 Current 1,387 3,249 420 5,056 Non-current 1,801 5,706 703 8,210 12/31/2024 Note Civil Labor Other Risks Total Opening balance - 01/01 3,203 7,821 2,141 13,165 (-) Provisions guaranteed by indemnity clause 2c XII (205) (962) - (1,167) Subtotal 2,998 6,859 2,141 11,998 Adjustment / Interest 23 122 515 - 637 Changes in the period reflected in income 23 1,487 3,539 325 5,351 Increase 2,062 3,958 325 6,345 Reversal (575) (419) - (994) Payment / Transfer (1,569) (3,371) (1,400) (6,340) Subtotal 3,038 7,542 1,066 11,646 (+) Provisions guaranteed by indemnity clause 2c XII 169 671 - 840 Closing balance 3,207 8,213 1,066 12,486 Current 1,535 3,443 115 5,093 Non-current 1,672 4,770 951 7,393 91 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 II - Tax and social security provisions Tax and social security provisions correspond to the principal amount of taxes involved in administrative or judicial tax lawsuits, subject to tax assessment notices, plus interest and, when applicable, fines and charges.

It also includes the financial margin on market trading, Treasury operating costs, and equity in earnings of companies not included in either of the other segments. a) Basis of Presentation Segment information is based on the reports used by senior management of ITAÚ UNIBANCO HOLDING to assess performance and to make decisions about allocation of funds for investment and other purposes. These reports use a variety of information for management purposes, including financial and non-financial information supported by bases different from information prepared according to accounting practices adopted in Brazil. The main indicators used for monitoring business performance are Recurring Income, and Return on Economic Capital allocated to each business segment. Information by segment has been prepared in accordance with accounting practices adopted in Brazil and is adjusted by the items below: Allocated capital: The statements for each segment consider capital allocation based on a proprietary model and consequent impacts on results arising from this allocation. This model includes the following components: credit risk, operating risk, market risk and insurance underwriting risk. Income tax rate: We take the total income tax rate, net of the tax effect from the payment of interest on capital, for the Retail Business, Wholesale Business and Activities with the Market + Corporation. The difference between the income tax amount calculated by segment and the effective income tax amount, as stated in the consolidated financial statements, is allocated to the Trading + Institutional column. • Reclassification and application of managerial criteria The managerial statement of income was used to prepare information per segment. These statements were obtained based on the statement of income adjusted by the impact of non-recurring events and the managerial reclassifications in income. The main reclassifications between the accounting and managerial results are: Operating revenues: Considers the opportunity cost for each operation. The financial statements were adjusted so that the stockholders' equity was replaced by funding at market price. Subsequently, the financial statements were adjusted to include revenues related to capital allocated to each segment. The cost of subordinated debt and the respective remuneration at market price were proportionally allocated to the segments, based on the economic capital allocated. Tax effects of hedging: The tax effects of hedging of investments abroad were adjusted – they were originally recorded as tax expenses (PIS and COFINS) and Income Tax and Social Contribution on Net Income – and are now reclassified to financial margin. Insurance: The main reclassifications of revenues refer to the financial margins obtained from technical provisions for insurance, pension plans and premium bonds, in addition to revenue from management of pension plan funds. Other reclassifications: Other Income, Share of profit or (loss) in Associates and joint ventures, Non- Operating Income, Profit Sharing of Management Members and Expenses for Credit Card Reward Program were reclassified to those lines representing the way the ITAÚ UNIBANCO HOLDING manages its business, to provide a clearer understanding of our performance. 94 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 The adjustments and reclassifications column shows the effects of the differences between the accounting principles followed for the presentation of segment information, which are substantially in line with the accounting practices adopted for financial institutions in Brazil, except as described above, and the policies used in the preparation of these consolidated financial statements according to IFRS. Significant adjustments are as follows: • Requirements for impairment testing of financial assets are based on the expected loan losses model. • Adjustment to fair value due to reclassifications of financial assets to categories of measurement at amortized cost, at fair value through profit or loss or at fair value through other comprehensive income, as a result of the concept of business models of IFRS 9. • Financial assets modified and not written-off, with their balances recalculated in accordance with the requirements of IFRS 9. • Effective interest rate of financial assets and liabilities measured at amortized cost, appropriating revenues and costs directly attributable to their acquisition, issue or disposal over the transaction term, whereas in the standards adopted in Brazil, recognition of expenses and revenues from fees occurs at the time these transactions are contracted. • Goodwill generated in a business combination is not amortized, whereas in the standards adopted in Brazil, it is amortized. 95 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 b) Consolidated Statement of Managerial Result 07/01 to 09/30/2025 Retail Business Wholesale Business Activities with the Market + Corporation ITAÚ UNIBANCO Adjustments IFRS consolidated (1) Operating revenues 28,349 15,879 2,339 46,567 (3,165) 43,402 Interest margin 17,846 11,425 2,111 31,382 (3,633) 27,749 Commissions and Banking Fees 7,393 4,257 105 11,755 (74) 11,681 Income from insurance and private pension operations before claim and selling expenses 3,110 197 123 3,430 (1,005) 2,425 Other revenues - - - - 1,547 1,547 Cost of Credit (8,013) (1,132) - (9,145) 1,655 (7,490) Claims (440) (9) - (449) 449 - Operating margin 19,896 14,738 2,339 36,973 (1,061) 35,912 Other operating income / (expenses) (13,247) (5,906) (705) (19,858) (2,335) (22,193) Non-interest expenses (11,487) (5,135) (533) (17,155) (2,693) (19,848) Tax expenses for ISS, PIS and COFINS and Other (1,760) (771) (172) (2,703) (24) (2,727) Share of profit or (loss) in associates and joint ventures - - - - 382 382 Income before income tax and social contribution 6,649 8,832 1,634 17,115 (3,396) 13,719 Income tax and social contribution (1,843) (2,681) (415) (4,939) 2,820 (2,119) Non-controlling interests (90) (200) (10) (300) 6 (294) Net income 4,716 5,951 1,209 11,876 (570) 11,306 09/30/2025 Total assets (*) - 1,840,921 1,387,653 112,042 2,996,463 (27,112) 2,969,351 Total liabilities - 1,766,603 1,301,035 57,212 2,780,697 (36,053) 2,744,644 (*) Includes: Investments in associates and joint ventures 2,598 - 6,151 8,749 1,849 10,598 Fixed assets, net 7,416 1,796 - 9,212 3,190 12,402 Goodwill and Intangible assets, net 8,346 9,244 - 17,590 6,234 23,824 1) The IFRS Consolidated figures do not represent the sum of the parties because there are intercompany transactions that were eliminated only in the consolidated statements.

Note 32 - Risk and Capital Management a) Corporate Governance To undertake and manage risks is one of the activities of ITAÚ UNIBANCO HOLDING. 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 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 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. 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’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’s employees in their daily routines are as follows: • Sustainability and customer satisfaction: the vision of ITAÚ UNIBANCO HOLDING 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 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. 102 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 • Risk pricing: ITAÚ UNIBANCO HOLDING 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 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, 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, who are responsible for risks and capital management performing delegated duties on these topics, and their decisions are monitored by the CGRC. To support this structure, the Risk Department has specialized officers to ensure, on an independent and centralized basis, that the institution’s risks and capital are managed in compliance with the established policies and procedures. ITAÚ UNIBANCO HOLDING’s risk management organizational structure complies with Brazilian and international regulations in place. Locally, the Bank follows the standards established by the Central Bank of Brazil (Bacen), particularly Resolution 4,557/17, which sets forth the risk and capital management structure of financial institutions, by the Securities and Exchange Commission (CVM) and by the Superintendence of Private Insurance (SUSEP), among other regulators and applicable standards. At the international level, ITAÚ UNIBANCO HOLDING follows the standards established by the Basel Committee for Banking Supervision, the Securities and Exchange Commission (SEC) of the United States and the local regulations of the countries where it is present. In addition, ITAÚ UNIBANCO HOLDING 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 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 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’s exposure, to ensure correct and timely corporate decisions. 103 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 • 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 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 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 guidelines, helping employees to conscientiously understand, identify, measure, manage and mitigate risks. 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. Considering the strategic guidelines of ITAÚ UNIBANCO HOLDING, 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 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’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’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 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. 104 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 • 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. 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 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 others. 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 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. 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. ITAÚ UNIBANCO HOLDING strictly controls the credit exposure of customers and counterparties, taking action to address situations in which the current exposure exceeds what is desirable. For this purpose, measures provided for in loan agreements are available, such as accelerated maturity or a requirement for additional collateral. 105 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 I.I - Collateral and policies for mitigating credit risk ITAÚ UNIBANCO HOLDING 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 also uses credit derivatives, such as single-name CDS, to mitigate credit risk of its securities portfolios. These instruments are priced based on models that use the fair value of market inputs, such as credit spreads, recovery rates, correlations and interest rates. I.II - Governance and measurement of expected credit loss Both the credit risk and the finance areas are responsible for defining the methods used to measure expected credit loss and for periodically assessing changes in the provision amounts. These areas monitor the trends observed in provisions for expected credit loss by business, in addition to establishing an initial understanding of the variables that may trigger changes in the allowance for loan losses, the probability of default (PD) or the loss given default (LGD). ITAÚ UNIBANCO HOLDING 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. Sensitivity analysis ITAÚ UNIBANCO HOLDING prepares studies on the impact of estimates in the calculation of expected credit loss. The expected credit loss models use three different scenarios: Optimistic, Base and Pessimistic. In Brazil, where operations are substantially carried out, these scenarios are combined by weighting their probabilities: 10%, 55% and 35%, respectively, which are updated so as to reflect the new economic conditions. For loan portfolios originated in other countries, the scenarios are weighted by different probabilities, considering regional economic aspects and conditions. The table below shows the amount of financial assets at amortized cost and at fair value through other comprehensive income, expected credit loss and the impacts on the calculation of expected credit loss in the adoption of 100% of each scenario: 09/30/2025 12/31/2024 Financial assets (1) Expected credit loss Reduction/(Increase) of expected credit loss Financial Assets (1) Expected credit loss Reduction/(Increase) of expected credit loss Pessimistic scenario Base scenario Optimistic scenario Pessimistic scenario Base scenario Optimistic scenario 1,467,433 (52,716) (478) 309 839 1,464,464 (52,936) (2,183) 538 1,347 1) Composed of Loan operations, lease operations and securities. Expected credit loss comprises Expected credit loss for Financial guarantees, Credit commitments and Credits to be released R$ (1,588) (R$ (4,928) at 12/31/2024). I.III - Classification of Credit Impairment Stages The accounting policy on expected credit loss is presented in Note 2c IV. ITAÚ UNIBANCO HOLDING uses customers’ internal information, statistic models, days of default and quantitative analysis in order to determine the credit risk of the financial assets. The rules of stage change consider for the Retail and Wholesale segments: • Stage 1 to stage 2: delay or assessment of probability of default (PD) triggers. ITAÚ UNIBANCO HOLDING migrates contracts overdue for over 30 days to stage 2, except real estate loans (overdue for 60 days), due to the operation risk. 106 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 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. • Stage 3: default parameters are used to identify stage 3, and the main ones are: 90 days overdue in the payment of principal and charges, debt restructuring, judicial measures, among others. The financial asset, at any stage, may migrate to stage 3 when presenting default parameters. Based on the classifications in stages, the measurement rules determined for expected credit loss in each stage are used, as described in Note 2c IV.

The repossessed assets intended for sale comprise, mainly, real estate and their sale includes periodic auctions that are previously disclosed to the market. Total repossessed assets in the period were R$ 474 (R$ 623 from 01/01 to 09/30/2024). 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, (v) monitoring of actions required to adjust positions and risk levels to make them realistic, and (vi) providing support for the safe launch of new financial products. The market risk structure categorizes transactions as part of either the banking portfolio or the trading portfolio, in accordance with general criteria established by CMN Resolution No. 4,557, of February 23, 2017, and BCB Resolution No. 111, of July 6, 2021, as amended. The trading portfolio consists of all transactions involving financial instruments and commodities, including derivatives, which are held for trading. The banking portfolio is basically characterized by transactions for the banking business, and transactions related to the management of the balance sheet of the institution, where there is no intention of sale and time horizons are medium and long term. Market risk management is based on the following metrics: • Value at risk (VaR): a statistical measure that estimates the expected maximum potential economic loss under normal market conditions, considering a certain time horizon and confidence level. • Losses in stress scenarios (Stress test): simulation technique to assess the behavior of assets, liabilities and derivatives of a portfolio when several risk factors are taken to extreme market situations (based on prospective and historical scenarios). • Stop loss/Max drawdown: metrics used to revise positions, should losses accumulated in a certain period reach a certain level. • Concentration: cumulative exposure of a certain financial instrument or risk factor, calculated at market value (MtM – Mark to Market). • Stressed VaR: statistical metric derived from the VaR calculation, with the purpose of simulating higher risk in the trading portfolio, taking returns that can be seen in past scenarios of extreme volatility. Management of Interest Rate Risk in the Banking Book (IRRBB) is based on the following metrics: • ΔEVE (Delta economic value of equity): difference between the present value of the sum of repricing flows of instruments subject to IRRBB in a base scenario and the present value of the sum of repricing flows of these instruments in a scenario of shock in interest rates. 114 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 • 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 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 polices of ITAÚ UNIBANCO HOLDING. 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’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 uses proprietary systems to measure the consolidated market risk. The processing of these systems occurs in a high-availability access-controlled environment, which has data storage and recovery processes and an infrastructure that ensures business continuity in contingency (disaster recovery) situations. II.I - VaR - Consolidated ITAÚ UNIBANCO HOLDING VaR is calculated by Historical Simulation, i.e. the expected distribution for profits and losses (P&L´s Profit and loss statement) of a portfolio over time, 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 historical period 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.

The currency (or foreign exchange) risk arises from positions that are sensitive to oscillations in foreign exchange rates. These positions may be originated by financial instruments that are denominated in a currency other than the functional currency in which the balance sheet is measured or through positions in derivative instruments (for negotiation or hedge). Sensitivity to currency risk is disclosed in the table VaR Total (Historical Simulation) described in item II.I – VaR Consolidated – ITAÚ UNIBANCO HOLDING. II.I.III - Share Price Risk The exposure to share price risk is disclosed in Note 5, related to Financial Assets through Profit or Loss - Securities, and Note 8, related to Financial Assets at Fair Value through Other Comprehensive Income - Securities. 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 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. ITAÚ UNIBANCO HOLDING manages and controls liquidity risk on a daily basis, using procedures approved in superior committees, including the adoption of liquidity minimum limits, sufficient to absorb possible cash losses in stress scenarios, measured with the use of internal and regulatory methods. Among the main regulatory liquidity indicators, the following indicators stand out: Liquidity Coverage Ratio (LCR): can be defined as a sufficiency index over a 30-day horizon, measuring the available amount of assets available to honor potential liquid outflows in a stress scenario. Net Stable Funding Ratio (NSFR): can be defined as an analysis of funding available for the financing of longterm assets. Both metrics are managed by the liquidity risk area and they have limits approved by superior committees, as well as governance of action plans in possible liquidity stress scenarios. Additionally, the following items for monitoring and supporting decisions are periodically prepared and submitted to senior management: • Different scenarios projected for changes in liquidity. • Contingency plans for crisis situations. • Reports and charts that describe the risk positions. • Assessment of funding costs and alternative sources of funding. 117 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 • Monitoring of changes in funding through a constant control of sources of funding, considering the type of investor, maturities and other factors. III.I - Primary sources of funding ITAÚ UNIBANCO HOLDING has different sources of funding, of which a significant portion is from the retail segment. Of total customers’ funds, 77.6% or R$ 1,213,216, is immediately available to customers. However, the historical behavior of the accumulated balance of the two largest items in this group – time deposit and interbank market funds - is relatively consistent with the balances increasing over time and inflows exceeding outflows for monthly average amounts.

III.II - Control over liquidity Under the LCR metric, ITAÚ UNIBANCO HOLDING has High-quality Liquid Assets (HQLA) which totaled an average of R$ 367,777 in the period, mainly made up of sovereign securities, reserves in central banks and cash. Net cash outflows totaled an average of R$ 168,176 in the period, mainly made up of retail, wholesale funds, additional requirements, contractual and contingent obligations, offset by cash inflows from loans and other expected cash inflows. The average LCR in the period is 218.7% (221.3% at 12/31/2024) above the 100% threshold, and therefore the entity comfortably has sufficient stable funds available to support losses under the standardized stress scenario for LCR. From the NSFR perspective, ITAÚ UNIBANCO HOLDING has Available Stable Funding (ASF) that totaled R$ 1,408,603 in the period, mainly made up of capital, retail and wholesale funds. The required stable funding (RSF) totaled R$ 1,142,829 in the period, mainly made up of loans and financing granted to wholesale and retail clients, central governments, and operations with central banks. The NSFR at the period closing is 123.3% (122.0% at 12/31/2024), above the 100% threshold, and therefore the entity comfortably has sufficient stable funds available to support the stable funds required in the long term, in accordance with the metric. 118 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 Liabilities according to their remaining contractual maturities, considering their undiscounted flows, are presented below: Undiscounted future flows, except for derivatives which are fair value 09/30/2025 12/31/2024 Financial liabilities 0 – 30 31 – 365 366 – 720 Over 720 days Total 0 – 30 31 – 365 366 – 720 Over 720 days Total Deposits 945,379 78,488 7,713 10,802 1,042,382 894,493 132,640 14,588 18,118 1,059,839 Savings 169,375 - - - 169,375 180,730 - - - 180,730 Interbank 1,950 3,042 998 1 5,991 1,497 1,451 3,848 770 7,566 Time deposit 645,709 75,446 6,715 10,801 738,671 580,855 131,189 10,740 17,348 740,132 Demand 127,801 - - - 127,801 124,920 - - - 124,920 Other deposits 544 - - - 544 6,491 - - - 6,491 Central Bank of Brazil deposits (149,681) (11,776) (1,049) (1,686) (164,192) (137,510) (19,100) (1,564) (2,524) (160,698) Savings (29,009) - - - (29,009) (30,763) - - - (30,763) Time deposit (100,783) (11,776) (1,049) (1,686) (115,294) (84,567) (19,100) (1,564) (2,524) (107,755) Demand (19,889) - - - (19,889) (22,180) - - - (22,180) Securities sold under repurchase agreements 381,902 41,666 1,309 140,492 565,369 352,257 23,772 572 77,597 454,198 Government securities 323,592 9,654 1,307 140,477 475,030 274,340 7,511 290 76,463 358,604 Corporate securities 25,267 20,003 - 4 45,274 27,191 15,642 282 1,134 44,249 Foreign 33,043 12,009 2 11 45,065 50,726 619 - - 51,345 Interbank market funds 266,156 47,175 38,963 52,936 405,230 189,700 114,859 33,650 60,238 398,447 Institutional market funds 1,683 10,177 66,253 85,482 163,595 5,163 15,436 54,277 100,802 175,678 Derivatives - Net position 15,599 28,520 10,620 24,373 79,112 10,775 29,805 12,566 32,267 85,413 Forward 12,495 1,931 143 24 14,593 1,435 2 - 13 1,450 Options 1,445 12,425 1,351 2,027 17,248 3,902 14,825 1,065 796 20,588 Swaps 397 9,423 7,259 21,263 38,342 3,187 7,957 10,065 30,185 51,394 Other derivatives 1,262 4,741 1,867 1,059 8,929 2,251 7,021 1,436 1,273 11,981 Other financial liabilities - - - - - 29 185 138 192 544 Total financial liabilities 1,461,038 194,250 123,809 312,399 2,091,496 1,314,907 297,597 114,227 286,690 2,013,421 Off-balance commitments 09/30/2025 12/31/2024 Note 0 – 30 31 – 365 366 – 720 Over 720 days Total 0 – 30 31 – 365 366 – 720 Over 720 days Total Financial guarantees 2,947 46,992 21,290 52,868 124,097 3,323 42,924 21,910 55,758 123,915 Credit commitments 241,996 61,414 20,295 230,278 553,983 192,814 53,056 19,647 234,297 499,814 Letters of credit to be released 58,239 - - - 58,239 72,930 - - - 72,930 Contractual commitments - Fixed and Intangible assets 13, 14 - - - 1 1 - - - - - Total 303,182 108,406 41,585 283,147 736,320 269,067 95,980 41,557 290,055 696,659 119 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 IV - 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. Once identified, these risks are monitored and reassessed annually or on demand until they cease to pose a risk or until they can be adequately measured, in which case the other steps of risk management are then followed. This process is ensured by ITAÚ UNIBANCO HOLDING’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. V - 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. Social, environmental and climatic factors are considered relevant to the business of ITAÚ UNIBANCO HOLDING, since they may affect the creation of shared value in the short, medium and long term. The Policy of Social, Environmental and Climatic Risks (Risks SAC Policy) establishes the guidelines and underlying principles for social, environmental and climatic risk management, addressing the most significant risks for the institution’s operation through specific procedures. Actions to mitigate the Social, Environmental and Climatic Risks are taken based on the mapping of processes, risks and controls, monitoring of new standards related to the theme and recording of occurrence in internal systems. In addition to the identification, the phases of prioritization, response to risk, mitigation, monitoring and reporting of assessed risks supplement the management of these risks at ITAÚ UNIBANCO HOLDING. In the management of Social, Environmental and Climatic Risks, business areas manage the risk in its daily activities, following the Risks SAC Policy guidelines and specific processes, with the support of specialized assessment from dedicated technical teams located in Credit, which serves the Wholesale segment, Credit Risk and Modeling, and Institutional Legal teams, that act on an integrated way in the management of all dimensions of the Social, Environmental and Climatic Risks related to the conglomerate’s activities. As an example of specific guidelines for the management of these risks, ITAÚ UNIBANCO HOLDING has specific governance for granting and renewing credit in senior approval levels for clients in certain economic sectors, classified as Sensitive Sectors (Mining, Steel & Metallurgy, Oil & Gas, Textiles Industry and Retail Clothing, Paper & Pulp, Chemicals & Petrochemicals, Agribusiness - Meatpacking, Agribusiness - Crop Protection and Fertilizers, Wood, Energy, Rural Producers and Real Estate), for which there is an individualized analysis of Social, Environmental and Climate Risks. The institution also counts on specific procedures for the Institution’s operation (stockholders’ equity, branch infrastructure, technology and suppliers), credit, investments and key controls. SAC Risks area, Internal Controls and Compliance areas, in turn, support and ensure the governance of the activities of the business and credit areas that serves the business. The Internal Audit acts on an independent manner, assessing risk management, controls and governance. Governance also counts on the Social, Environmental and Climatic Risks Committee, whose main responsibility is to assess and deliberate about institutional and strategic matters, as well as to resolve on products, operations, services, among others involving the Social, Environmental and Climatic Risks. Climate Risk includes: (i) physical risks, arising from changes in weather patterns, such as increased rainfall, and temperature and extreme weather events, and (ii) transition risks, resulting from changes in the economy, as a result of climate actions, such as carbon pricing, climate regulation, market risks and reputational risks. 120 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 Considering its relevance, climate risk has become one of the main priorities for ITAÚ UNIBANCO HOLDING, which supports the Task Force on Climate-related Financial Disclosures (TCFD) and it is committed to maintaining a process of evolution and continuous improvement within the pillars recommended by the TCFD. With this purpose, ITAÚ UNIBANCO HOLDING is strengthening the governance and strategy related to Climate Risk and developing tools and methodologies to assess and manage these risks. ITAÚ UNIBANCO HOLDING measures the sensitivity of the credit portfolio to climate risks by applying the Climate Risk Sensitivity Assessment Tool, developed by Febraban. The tool combines relevance and proportionality criteria to identify the sectors and clients within the portfolio that are more sensitive to climate risks, considering physical and transition risks. The sectors with the highest probability of suffering financial impacts from climate change, following the TCFD guidelines, are: energy, transport, materials and construction, agriculture, food and forestry products. c) Capital Management Governance ITAÚ UNIBANCO HOLDING is subject to the regulations of BACEN, which determines minimum capital requirements, procedures to obtain information to assess the global systemic importance of banks, fixed asset limits, loan limits and accounting practices, and requires banks to conform to the regulations based on the Basel Accord for capital adequacy. Additionally, CNSP and SUSEP issue regulations on capital requirements that affect our insurance operations and private pension and premium bonds plans. The notes about capital were prepared in accordance with BACEN’s regulatory requirements and with internationally accepted minimum requirements according to the Bank for International Settlements (BIS). I - Composition and Capital Adequacy The Board of Directors is the body responsible for approving the institutional capital management policy and guidelines for the capitalization level of ITAÚ UNIBANCO HOLDING. 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. The result of the last ICAAP, which comprises stress tests – which was dated December 2024 – indicated that ITAÚ UNIBANCO HOLDING 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 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. 09/30/2025 12/31/2024 Available capital (amounts) Common Equity Tier 1 (CET 1) 195,917 188,265 Tier 1 215,466 206,196 Total capital (PR) 238,430 227,602 Risk-weighted assets (amounts) Total risk-weighted assets (RWA) 1,454,242 1,379,056 Risk-based capital ratios as a percentage of RWA Common Equity Tier 1 ratio (%) 13.5% 13.7% Tier 1 ratio (%) 14.8% 15.0% Total capital ratio (%) 16.4% 16.5% 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% 121 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 At 09/30/2025, the amount of perpetual subordinated debt that makes up Tier I capital is R$ 18,599 (R$ 16,957 at 12/31/2024) and the amount of perpetual subordinated debt that makes up Tier capital II is R$ 21,813 (R$ 20,497 at 12/31/2024). The Basel Ratio reached 16.4% at 09/30/2025, a reduction of 0.1 p.p. in relation to that calculated at 12/31/2024. The variation reflects the effects of interest payments on capital and additional dividends, share repurchase and growth in risk-weighted assets, offset by the positive impact of income in the period. Additionally, ITAÚ UNIBANCO HOLDING has a surplus over the required minimum Total capital of R$ 122,091 (R$ 117,278 at 12/31/2024), well above the Capital Buffer requirement of R$ 51,806 (R$ 49,049 at 12/31/2024), widely covered by available capital. The fixed assets ratio indicates the commitment percentage of adjusted Total capital with adjusted permanent assets. ITAÚ UNIBANCO HOLDING falls within the maximum limit of 50% of adjusted Total capital, established by BACEN. At 09/30/2025, fixed assets ratio reached 17.7% (18.5% at 12/31/2024), showing a surplus of R$ 77,101 (R$ 71,704 at 12/31/2024). 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.

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’s results, liquidity and capital. The institution has been carrying out this test in order to assess its solvency in plausible scenarios of crisis, as well as to identify areas that are more susceptible to the impact of stress that may be the subject of risk mitigation. For the purposes of the test, the economic research area estimates macroeconomic variables for each stress scenario. The elaboration of stress scenarios considers the qualitative analysis of the Brazilian and the global conjuncture, historical and hypothetical elements, short and long term risks, among other aspects, as defined in CMN Resolution 4,557. In this process, the main potential risks to the economy are assessed based on the judgment of the bank's team of economists, endorsed by the Chief Economist of ITAÚ UNIBANCO HOLDING 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 uses the simulations to manage its portfolio risks, considering Brazil (segregated into wholesale and retail) and External Units, from which the risk-weighted assets and the capital and liquidity ratios are derived. The stress test is also an integral part of the ICAAP, the main purpose of which is to assess whether, even in severely adverse situations, the institution would have adequate levels of capital and liquidity, without any impact on the development of its activities. This information enables potential offenders to the business to be identified and provides support for the strategic decisions of the Board of Directors, the budgeting and risk management process, as well as serving as an input for the institution’s risk appetite metrics. V - Leverage Ratio The Leverage Ratio is defined as the ratio between Tier I Capital and Total Exposure, calculated according to BACEN Circular 3,748, which minimum requirement is 3%. The ratio is intended to be a simple measure of nonrisk- sensitive leverage, and so it does not take into account risk weights or risk mitigation. d) Management risks of insurance contracts and private pension I - Management structure, roles and responsibilities ITAÚ UNIBANCO HOLDING has specific committees, whose assignment is to define and establish guidelines for the management of funds from insurance contracts and private pension, with the objective of long-term profitability, and to establish assessment models, risk limits and resource allocation strategies in defined financial assets. 123 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 II - Underwriting risk In addition to the risks inherent in financial instruments related to insurance contracts and private pension, operations carried out at ITAÚ UNIBANCO HOLDING cause exposure to underwriting risk. Underwriting risk is the risk of significant deviations in the methodologies and/or assumptions used for pricing products that may adversely affect ITAÚ UNIBANCO HOLDING, which may be consummated in different ways, depending on 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 incurred, contrary to pricing estimates. (ii) Private Pension: is observed in the increase in life expectancy or deviation from the assumptions adopted in the estimates of future cash flows. The measurement of exposure to underwriting risk is based on the analysis of the actuarial assumptions adopted in the recognition of liabilities and pricing of products through i) monitoring the evolution of equity required to mitigate the risk of insolvency or liquidity; ii) follow-up of portfolios, products, and coverage, from the perspective of results, adherence to expected rates and expected behavior of loss ratio. Exposure to underwriting risk is managed and monitored in accordance with risk appetite levels approved by Management and is controlled using indicators that allow the creation of stress scenarios and simulations of the portfolio. II.I Risk Concentrations ITAÚ UNIBANCO HOLDING's insurance and private pension operations are mainly related to death and survivorship coverage. II.II - Sensitivity analysis The sensitivity analysis considers a vision impacts caused by changes in assumptions, which could affect the income and stockholders’ equity at the report date. This type of analysis is usually conducted under the ceteris paribus condition, in which the sensitivity of a system is measured when one variable of interest is changed and all the others remain unchanged. The results obtained are shown in the table below: Assumptions Impact in income Impact in stockholders’ equity Insurance Private pension Insurance Private pension Discount rate 0.5 p.p. increase - (35) 50 528 0.5 p.p. decrease - 25 (54) (579) Biometric tables 5% increase (22) 49 - - 5% decrease 23 (51) - - Claims 5% increase (30) - - - 5% decrease 30 - - - III - Liquidity risk Liquidity risk management for insurance and private pension operations is performed on an ongoing basis, based on monitoring the flow of payments related to its liabilities, the flow of receipts generated by operations and the portfolio of financial assets. Financial assets are managed with the purpose of optimizing the relationship between risk and return on investments, considering the characteristics of their liabilities. Accordingly, investments are concentrated in government and corporate securities with good credit quality in active and liquid markets, keeping a considerable amount invested in short-term assets, with immediate liquidity, to meet regular and contingent liquidity needs. In addition, ITAÚ UNIBANCO HOLDING constantly monitors the solvency conditions of its operations. 124 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 Below is a maturity analysis of estimated discounted future cash flows from insurance contracts and private pension, considering assumptions of inflows, outflows and discount rates (Note 27c): Period 09/30/2025 12/31/2024 Insurance Private pension Total Insurance Private pension Total 1 year (443) 13,478 13,035 (159) 13,469 13,310 2 years (348) 13,834 13,486 (295) 13,538 13,243 3 years (231) 13,941 13,710 (194) 12,380 12,186 4 years (111) 13,953 13,842 (91) 12,219 12,128 5 years (4) 13,845 13,841 1 12,178 12,179 Over 5 years 958 242,841 243,799 884 215,436 216,320 Total (1,2) (179) 311,892 311,713 146 279,220 279,366 1) Refers to (inflows) and outflows of cash flows related to insurance contracts and private pension. 2) For better presentation and comparability, comparative balances have been reclassified according to current criteria. ITAÚ UNIBANCO HOLDING holds R$ 330,662 (R$ 295,823 at 12/31/2024) referring to amounts that are payable or demand, which represent contributions made by insured parties that can be redeemed at any time. All these amounts refer to contracts issued that are liabilities, and no group of contracts was in asset position in the period. IV - Credit risk The credit risk arising from insurance contract premiums is not material, as cases with unpaid coverage are canceled after 90 days. Reinsurance operations are controlled through an internal policy, observing the regulator's guidelines regarding the reinsurers with which ITAÚ UNIBANCO HOLDING operates. Taking out reinsurance is subject to an assessment of the reinsurer's credit risk and the operational limits for its consummation, and monitoring is carried out during the effectiveness to identify signs of deterioration that lead to changes in the analyzes conducted. 125 Itaú Unibanco Holding S.A. – Condensed Financial Statements in IFRS – September 30, 2025 Note 33 - Supplementary information a) Reconciliation of Net income and Stockholders’ equity The Individual Financial Statements of Itaú Unibanco Holding S.A. are prepared in accordance with the Accounting Standard of Institutions Regulated by the Central Bank of Brazil (Cosif) differently from these Consolidated Financial Statements in accordance with international financial reporting standards (IFRS) issued by the International Accounting Standards Board (IASB) (currently referred to by the IFRS Foundation as “IFRS accounting standards”).
