c) Critical accounting estimates and judgments The preparation of Consolidated Financial Statements requires Management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and contingent assets and liabilities at the date of the Financial Statements, due to uncertainties and the high level of subjectivity involved in the recognition and measurement of certain items. Estimates and judgments that present a significant risk and may have a material impact on the values of assets and liabilities are disclosed below. Actual results may differ from those established by these estimates and judgments. Topic Notes Consolidation 2c (I) and 2b Fair value of financial instruments 2c (II) and 15 Provision for loan losses 2c (III) and 6 Goodwill impairment 2c (IV) and 12 Deferred income tax and social contribution 2c (V) and 10 Defined benefit pension plans 2c (VI) and 17 Provisions, contingencies and legal obligations 2c (VII) and 8 (I) Consolidation—subsidiaries are all those in which ITAÚ UNIBANCO HOLDING PRUDENTIAL, either directly or through other subsidiaries, is the holder of partner rights that permanently ensure preponderance in corporate resolutions and the power to elect the majority of managers. The existence of control is assessed continuously. Subsidiaries are consolidated from the date control is established to the date on which it ceases to exist. The consolidated financial statements are prepared using consistent accounting policies. Intercompany asset and liability account balances, income accounts and transaction values have been eliminated. (II) Fair value of financial instruments—the fair value of financial instruments, including derivatives that are not traded in active markets, is calculated by using valuation techniques based on assumptions that consider market information and conditions. The main assumptions are: historical data, information on similar transactions and pricing techniques. For more complex or illiquid instruments, significant judgment is necessary to determine the model used with the selection of specific inputs and, in certain cases, evaluation adjustments are applied to the model amount our price quoted for financial instruments that are not actively traded. The methodologies used to estimate the fair value of certain financial instruments are described in Note 15. (III) Provision for loan losses – The analysis of the provision for loan losses from the operations granted by ITAÚ UNIBANCO HOLDING PRUDENTIAL is conducted based on the assessment of the default classification (Ratings AA-H), on an individual or collective basis, established in CMN Resolution No. 2,682, of December 21, 1999. Management exercises its judgment in the assessment of the adequacy of the expected loss amounts resulting from models and, according to its experience, makes adjustments that may result from certain clients’ credit condition or from temporary adjustments resulting from new situations or circumstances that have not yet been reflected in modeling. In addition to the default classification the following aspects are also considered: • 12-month horizon, using base macroeconomic scenarios, i.e., with no weighting; and • Highest risk classification according to the operation, client, default, renegotiation, among others. The criteria for the provision for loan losses are detailed in Note 19. (IV) Goodwill impairment – The review of goodwill due to impairment reflects the Management’s best estimate for future cash flows of Cash Generating Units (CGU), with the identification of the CGU and estimate of their fair value less costs to sell and/or value in use. To determine this estimate, ITAÚ UNIBANCO HOLDING PRUDENTIAL adopts the discounted cash flow methodology for a period of 5 years, macroeconomic assumptions, growth rate and discount rate. Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.4

The discount rate generally reflects financial and economic variables, such as the risk-free interest rate and a risk premium. Cash-Generating Units or CGU groups are identified at the lowest level at which goodwill is monitored for internal management purposes. (V) Deferred income tax and social contribution—deferred tax assets are recognized only in relation to deductible temporary differences, tax losses and social contribution loss carryforwards for offset to the extent that i) it is considered probable that ITAÚ UNIBANCO HOLDING PRUDENTIAL will generate future taxable income for its use; and ii) it presents a history of taxable income or income in at least three of the last five fiscal years. The expected realization of deferred tax assets is based on the projection of future taxable profits and technical studies, as disclosed in Note 10. (VI) Defined benefit pension plans—the current amount of pension plans is obtained from actuarial calculations, which use assumptions such as discount rate, which is appropriated at the end of each year and used to determine the present value of estimated future cash outflows. To determine the appropriate discount rate, ITAÚ UNIBANCO HOLDING PRUDENTIAL considers the interest rates of National Treasury Notes that have maturity terms similar to the terms of the respective liabilities. The main assumptions for Pension plan obligations are partly based on current market conditions. Additional information is disclosed in Note 17. (VII) Provisions, Contingencies and Legal Obligations—ITAÚ UNIBANCO HOLDING PRUDENTIAL periodically reviews its contingencies. These contingencies are evaluated based on management´s best estimates, taking into account the opinion of legal counsel when there is a likelihood that financial resources will be required to settle the obligations and the amounts may be reasonably estimated. Contingencies classified as probable losses are recognized in the Consolidated Balance Sheet under Provisions. Contingent amounts are measured using appropriate models and criteria, despite the uncertainty surrounding the ultimate timing and amounts. Provisions, contingencies and other commitments are detailed in Note 8. d) Business development Reduction of non-controlling interest in XP Inc. On November 26, 2020, ITAÚ UNIBANCO HOLDING disclosed that the Board of Directors approved the partial spin-off of the investment held in XP Inc. (XP INC) to a new company (XPart S.A.). On December 2 and 17, 2020, ITAÚ UNIBANCO HOLDING sold 4.44% and 0.07%, respectively, of its investments in XP INC, through the public offering on the Nasdaq, giving a result before taxes of R$ 4,001. Concurrently with the sales, XP INC completed a public offering (follow-on) which resulted in the dilution of the interest held by ITAÚ UNIBANCO HOLDING to 41.00% of capital, giving a result in XP INC primary subscription of R$ 546. Additionally, on May 14, 2021, ITAÚ UNIBANCO HOLDING sold 0.48% of its interest in XP INC, generating income before taxes of R$ 486.

In General Meetings on October 1, 2021, the merger of XPart S.A. into XP INC. was approved.

Note 3 – Significant accounting policies a) Cash and cash equivalents—Defined as cash and current accounts with banks, shown in the Consolidated Balance Sheet under the heading Cash, Interbank Deposits, Money Market (Collateral Held) and Voluntary investments with the Central Bank of Brazil with original maturities not exceeding 90 days. b) Interbank investments, Remunerated restricted Credits held at the Central Bank of Brazil (BACEN), Remunerated deposits, deposits received under securities repurchase agreements, funds from acceptances and issuance of securities, borrowing and onlending, subordinated debt and other receivables and payables – Operations with fixed interest and charges are booked at present value. Operations with floating interest and charges are booked at the adjusted principal amount. Operations subject to foreign exchange variation are booked at the corresponding amount in local currency. Liabilities are presented net of the transaction costs incurred, if significant, calculated pro rata on a daily basis. c) Securities—Recorded at the cost of acquisition restated by the index and/or effective interest rate and presented in the Balance Sheet as required by BACEN Circular 3,068, of November 08, 2001. Securities are classified into the following categories: · Trading securities – Securities acquired to be actively and frequently traded. They are measured at fair value, with a counterparty to the results for the period; · Available for sale securities – Securities that can be negotiated but are not acquired for the purposes of active and frequent trading. They are measured at fair value, with a counterparty to a specific account in stockholders’ equity; · Held to maturity securities –Securities, other than non-redeemable shares, which the bank has the financial capacity and intends, or is required, to hold in the portfolio to maturity. They are recorded at the cost of acquisition, or at fair value, whenever these are transferred from another category. Securities are adjusted up to maturity date, but are not measured at fair value. Gains and losses on available for sale securities, when realized, are recognized on the trade date in the statement of income, with a counterparty to a specific account in stockholders’ equity. Decreases in the fair value of available for sale and held to maturity securities below to cost, resulting from causes not considered to be temporary, are recorded in the results as realized losses. d) Derivative financial instruments—These are classified on the date of their acquisition, according to whether or not management intends to use them for hedging, according to BACEN Circular 3,082, of January 30, 2002. Transactions involving financial instruments, carried out at a customer’s request, for the bank’s own account, or which do not comply with the hedging criteria (mainly derivatives used to manage overall risk exposure), are stated at fair value, including realized and unrealized gains and losses, which are recorded directly in the statement of income. Derivatives that are used for protection against risk exposure or to modify the characteristics of financial assets and liabilities, where changes in fair value are closely related to those of the items being protected at the beginning and throughout the duration of the contract, and which are considered to be effective in reducing the risk exposure in question, are classified as hedges of the following types: · Market Risk Hedge – Financial assets and liabilities, as well as their related financial instruments, are booked at fair value, plus realized and unrealized gains and losses, which are recorded directly in the statement of income; · Cash Flow Hedge—The effective portion of a hedge of financial assets and liabilities, and the related financial instruments, are booked at fair value plus realized and unrealized gains and losses, net of tax effects, when applicable, and recorded in a specific account in stockholders’ equity. The ineffective portion is recorded directly in the statement of income; Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.7

· Hedge of Net Investments in Foreign Operations—Accounted for similarly to a cash flow hedge, i.e. the portion of gains or losses on a hedging instrument that is determined to be an effective hedge is recognized in stockholders’ equity, and reclassified to income for the period in the event of the disposal of the foreign operation. The ineffective portion is recognized in income for the period. e) Loans, leases and other credit operations (operations with lending characteristics) – These transactions are recorded at present value and calculated pro rata on a daily basis in line with variations in a defined indexer and interest rate, and are adjusted up to the 60th day of arrears, according to the expectation of payment. After the 60th day, income is recognized only on actual receipt of payments. Credit card operations include receivables arising from purchases made by cardholders. Funds corresponding to these amounts to be paid to the credit card companies are shown as liabilities, under the heading Interbank Accounts – Receipts and Payments Pending Settlement. f) Provision for loan losses—The balance of the provision for loan losses is recorded based on a credit risk analysis, at an amount considered sufficient to cover loan losses in accordance with the rules determined by CMN Resolution Nº. 2,682 of December 21, 1999, which include the following: · Provisions are recorded from the date on which loans are granted, based on the customer’s risk rating and on a periodic quality assessment of customers and business sectors, and not only in the event of default; · Exclusively in the case of default, losses are written off 360 days after the credits have matured, or after 540 days for operations with maturities longer than 36 months. g) Other assets—They are comprised of Assets Held for Sale, relating to real estate, vehicles and other assets available for sale (owned but deactivated, received as payment in kind or resulting from execution of guarantees). These assets are adjusted to fair value by setting up a provision in accordance with current regulations and prepaid expenses, corresponding to disbursements which will produce benefits in future years. h) Investments—Include goodwill identified in the acquisition of associates and joint ventures, net of any accumulated impairment loss. They are initially recognized at acquisition cost and are subsequently accounted for under the equity method. · Associates: are companies over which ITAÚ UNIBANCO HOLDING PRUDENTIAL has significant influence, but which it does not control. · Joint Ventures: ITAÚ UNIBANCO HOLDING PRUDENTIAL has joint venture whereby the parties that have joint control of the arrangement have rights to the net assets. i) Fixed assets—Are booked at their acquisition cost less accumulated depreciation and adjusted for impairment, if applicable. Depreciation is calculated on the straight-line method using rates based on the estimated useful lives of these assets. Such rates and other details are presented in Note 11. The residual values and useful lives of assets are reviewed and adjusted, if appropriate, at the end of each period. ITAÚ UNIBANCO HOLDING PRUDENTIAL reviews its assets in order to identify indications of impairment in their recoverable amounts. The recoverable amount of an asset is defined as the higher of its fair value less the cost to sell and its value in use. For the purposes of assessing impairment, assets are grouped at the lowest level for which independent cash flows can be identified (cash-generating units). The assessment may be made at an individual asset level when the fair value less the cost to sell can be reliably determined. j) Goodwill – Corresponds to the amount paid in excess in the acquisition of investments and it is amortized based on the expected future profitability or on its realization. It is semiannually submitted to the asset impairment test with the adoption of an approach that involves the identification of cash-generating units (CGU) and the estimate of its fair value less the cost to sell and/or its value in use. The breakdown of intangible assets is described in Note 12. Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.8

k) Intangible assets – Composed of: (i) Goodwill paid upon acquisition of a company, transferred to intangible assets due to merger of the acquired company’s equity into the acquirer company; (ii) Rights on the acquisition of payrolls and association agreements, amortized according to agreement terms or as economic benefits flow to the company; and (iii) Software, amortized over five years, and customer portfolios, amortized within ten years. Intangible assets with definite useful lives are amortized using the straight-line method over their estimated useful lives and those with indefinite useful lives are tested on a semiannually basis to identify possible impairment losses. l) 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 consolidated stockholders’ equity. m) Provisions, Contingent Assets and Contingent Liabilities – these are possible rights and potential obligations arising from past events for which realization depends on uncertain future events. Contingent assets are not recognized in the Consolidated Balance Sheet, except when Management of ITAÚ UNIBANCO HOLDING PRUDENTIAL considers that realization is practically certain. In general they correspond to lawsuits with favorable outcomes in final and unappealable judgments and to the withdrawal of lawsuits as a result of a settlement payment received or an agreement for set-off against an existing liability. These contingencies are evaluated based on Management’s best estimates, and are classified as: · Probable: in which liabilities are recognized in the Consolidated Balance Sheet under Provisions; · Possible: which are disclosed in the Consolidated Financial Statements, but no provision is recorded; · Remote: which require neither a provision nor disclosure. The amount of deposits in guarantee is adjusted in compliance with current legislation. Contingencies guaranteed by indemnity clauses in privatization processes and others, and with liquidity are recognized upon judicial notification with simultaneous recognition of receivables, without any effect on results. Legal Obligations and Tax and Social Security Obligations Represented by amounts payable for tax liabilities, the legality or constitutionality of which are subject to judicial challenge, recognized for the full amount under discussion. n) Allowance for Financial Guarantees Provided – Recognized based on the expected loss model, in an amount sufficient to cover any probable losses over the whole guarantee period. o) Income Tax and Social Contribution – There are two components of the provision for income tax and social contribution: current and deferred. The current component is approximately the total of taxes to be paid or recovered during the reporting period. Deferred income tax and social contribution, represented by deferred tax assets and liabilities, is obtained based on the differences between the tax bases of assets and liabilities and the amounts reported in the financial statements at each period. The income tax and social contribution expense is recognized in the Consolidated statement of income under Income Tax and Social Contribution, except when it refers to items directly recognized in Stockholders’ Equity, such as tax on marking available for sale financial assets to fair value, post-employment benefits and tax on cash flow hedges and hedge of net investment in foreign operations. Subsequently, these items are recognized in income upon realization of the gain/loss on the instruments. Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.9

Changes in tax legislation and rates are recognized in the Consolidated statement of income under Income tax and social contribution in the period in which they are enacted. Interest and fines are recognized in the Consolidated statement of income under Other administrative expenses. Tax rates, as well as their calculation bases, are detailed in Note 10. p) Deferred income – this refers to: (i) interest received in advance on which there is no prospect of demand for payment and which depends only on the passage of time to be appropriated to effective income, and (ii) the negative goodwill on acquisition of investments, which has not been absorbed in the consolidation process. q) Post-employments benefits Pension plans—defined benefit plans The liability (or asset, as the case may be) is recognized in the consolidated balance sheet with respect to a defined benefit plan corresponds to the present value of the defined benefit obligations at the balance sheet date less the fair value of the plan assets. The defined benefit obligations are calculated annually using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated amount of future cash flows of benefit payments at the rate for Brazilian treasury long term securities denominated in Reais and with maturity periods similar to the term of the pension plan liabilities. Pension plans—defined contribution For defined contribution plans, contributions to plans made by ITAÚ UNIBANCO HOLDING PRUDENTIAL, through pension plan funds, are recognized as expenses, when due. Other post-employment benefit obligations Like defined benefit pension plans, these obligations are assessed annually by independent, qualified actuaries, and the costs expected from these benefits are accrued over the period of employment. Gains and losses arising from changes in practices and variations in actuarial assumptions are recognized in Stockholders’ equity, in the period in which they occur. r) Foreign currency translation I—Functional and presentation currency The Financial Statements of ITAÚ UNIBANCO HOLDING PRUDENTIAL are presented in Brazilian Reais, its functional and presentation currency. For each subsidiary, joint venture or investment in associates, ITAÚ UNIBANCO HOLDING PRUDENTIAL defines the functional currency as the currency of the primary economic environment in which the entity operates. II—Foreign Currency Operations Foreign currency operations are translated into the functional currency using the exchange rates prevailing on the dates of the transactions. Foreign exchange gains and losses are recognized in the Consolidated Statement of Income, unless they are related to cash flow hedges and hedge of net investments in foreign operations, which are recognized in Stockholders’ Equity.

f) Derivative financial instruments ITAÚ UNIBANCO HOLDING PRUDENTIAL trades in derivative financial instruments with various counterparties to manage its overall exposure and to assist its customers in managing their own exposure. Futures – Interest rate and foreign currency futures contracts are commitments to buy or sell a financial instrument at a future date, at an agreed price or yield, and may be settled in cash or through delivery. The notional amount represents the face value of the underlying instrument. Commodity futures contracts or financial instruments are commitments to buy or sell commodities (mainly gold, coffee and orange juice) at a future date, at an agreed price, which are settled in cash. The notional amount represents the quantity of such commodities multiplied by the future price on the contract date. Daily cash settlements of price movements are made for all instruments. Forwards – Interest rate forward contracts are agreements to exchange payments on a specified future date, based on the variation in market interest rates from trade date to contract settlement date. Foreign exchange forward contracts represent agreements to exchange the currency of one country for the currency of another at an agreed price, on an agreed settlement date. Financial instrument forward contracts are commitments to buy or sell a financial instrument on a future date at an agreed price and are settled in cash. Swaps – Interest rate and foreign exchange swap contracts are commitments to settle in cash on a future date or dates the differentials between specific financial indices (either two different interest rates in a single currency or two different rates each in a different currency), as applied to a notional principal amount. Swap contracts shown under Other in the table below correspond substantially to inflation rate swap contracts. Options – Option contracts give the purchaser, for a fee, the right, but not the obligation, to buy or sell a financial instrument within a limited time, including a flow of interest, foreign currencies, commodities, or financial instruments at an agreed price that may also be settled in cash, based on the differential between specific indices. Credit Derivatives – Credit derivatives are financial instruments with value deriving from the credit risk on debt issued by a third party (the reference entity), which permits one party (the buyer of the hedge) to transfer the risk to the counterparty (the seller of the hedge). The seller of the hedge must pay out as provided for in the contract if the reference entity undergoes a credit event, such as bankruptcy, default or debt restructuring. The seller of the hedge receives a premium for the hedge but, on the other hand, assumes the risk that the underlying instrument referenced in the contract undergoes a credit event, and the seller may have to make payment to the purchaser of the hedge for up to the notional amount of the credit derivative. ITAÚ UNIBANCO HOLDING PRUDENTIAL buys and sells credit protection in order to meet the needs of its customers, management and mitigation of its portfolios’ risk. CDS (Credit Default Swap) is a credit derivative in which, upon a default related to the reference entity, the protection buyer is entitled to receive the amount equivalent to the difference between the face value of the CDS contract and the fair value of the liability on the date the contract was settled, also known as the recovered amount. The protection buyer does not need to hold the debt instrument of the reference entity for it to receive the amounts due pursuant to the CDS contract terms when a credit event occurs. TRS (Total Return Swap) is a transaction in which a party swaps the total return of an asset or of a basket of assets for regular cash flows, usually interest and a guarantee against capital loss. In a TRS contract, the parties do not transfer the ownership of the assets. The total value of margins pledged in guarantee by ITAÚ UNIBANCO HOLDING PRUDENTIAL was R$ 4,043 (R$ 14,860 at 12/31/2020) and was basically comprised of government securities. Further information on internal controls and parameters used to manage risks may be found in Note 19—Risk, Capital Management and Fixed Asset Limits.

g) Sensitivity analysis (trading and banking portfolios) ITAÚ UNIBANCO HOLDING PRUDENTIAL carried out a sensitivity analysis for each market risk factor considered significant. The biggest losses arising, by risk factor, in each scenario, were stated together with their impact on the results, net of tax effects, providing an overview of ITAÚ UNIBANCO HOLDING PRUDENTIAL’s exposure under exceptional scenarios. The sensitivity analyses of the banking and the trading portfolio shown in this report are a static evaluation of the portfolio exposure and, therefore, do not take into account management’s quick response capacity (treasury and control areas), which triggers risk mitigating measures whenever a situation of loss or high risk is identified, thus minimizing the possibility of significant losses. In addition, the study’s sole purpose is to show the exposure to risk and the respective protective actions, taking into account the fair value of financial instruments, irrespective of the accounting practices adopted by ITAÚ UNIBANCO HOLDING PRUDENTIAL.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.40 Note 8 – Provisions, Contingent Assets and Contingent Liabilities In the ordinary course of its business, ITAÚ UNIBANCO HOLDING PRUDENTIAL may be a party to legal proceedings to 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 PRUDENTIAL’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 PRUDENTIAL is not a party to this or any other administrative proceedings or lawsuits, in addition to those highlighted troughout 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. The lawsuits are classified as follows: Collective lawsuits: Related to claims of a similar nature and with individual amounts that are not considered significant. Provisions are calculated on a monthly basis and the expected amount of losses is accrued according to statistical references that take into account the nature of the lawsuit and the characteristics of the court (Small Claims Court or Regular Court). Contingencies and provisions are adjusted to reflect the amounts deposited into court as guarantee for their execution when realized. Individual lawsuits: Related to claims with unusual characteristics or involving significant amounts. The probability of loss is ascertained periodically, based on the amount claimed and the special nature of each case. The amounts considered as probable losses are recorded as provisions. ITAÚ UNIBANCO HOLDING PRUDENTIAL, 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 plants 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. ITAÚ UNIBANCO HOLDING PRUDENTIAL 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. The Federal Supreme Court (STF) has issued some decisions favorable to savings account holders, but it has not established its understanding with respect to the constitutionality of the economic plans and their applicability to savings accounts. Currently, the appeals involving these matters are suspended, by order of the STF, until it pronounces its final decision. 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 the economic plans, and ITAÚ UNIBANCO HOLDING PRUDENTIAL 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 increase 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 this term may be extended for another 30 months, subject to the reporting of the number of adhesions over the first period.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.41 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. These lawsuits are classified as follows: Collective lawsuits: related to claims considered similar and with individual amounts that are not considered significant. The expected amount of loss is determined and accrued on a monthly basis in accordance with a statistical model which calculates the amount of the claims and it is reassessed taking into account court rulings. Provisions and contingencies are adjusted to reflect the amounts deposited into court as security for execution. Individual lawsuits: related to claims with unusual characteristics or involving significant amounts. These are periodically calculated based on the amounts claimed. The probability of loss is estimated in accordance with the actual and legal characteristics of each lawsuit. Other Risks These are quantified and accrued on the basis of the value of rural credit transactions with joint liability and FCVS (salary variations compensation fund) credits assigned to Banco Nacional.

Goodwill and Intangible Assets from Aquisition are mainly represented by Itaú CorpBanca’s goodwill in the amount of R$ 2,581 (R$ 3,530 at 12/31/2020). ITAÚ UNIBANCO HOLDING PRUDENTIAL recognized on June 30, 2020, adjustments to the recoverable amount of goodwill and intangible assets related to Itaú Corpbanca, in the amounts of R$ 1,593 and R$ 789. The value in use of the Cash Generating Unit (CGU) in which Itáu CorpBanca is allocated was considered and cash flows were based on the result of June 2020 and internal projects of results until 2025. The adjustment to recoverable amount results from economic conditions on June 30, 2020, of Itaú CorpBanca’s market capitalization, discount rates applicable and other changes in variables triggered by the current uncertain macroeconomic condition that, when combined, resulted in a CGU amount lower than its book value. The discount rates used for the impairment test were 10.4% for operations in Chile and 12.3% for operations in Colombia, determined by the cost of capital calculated based on CAPM model. Long-term interest rates considered were 5.2% p.a. and 6.5% p.a. for Chile and Colombia, respectively. The most sensitive assumptions are cost of capital and perpetuity growth rate. (3) Other intangible assets: includes the effect of R$ 2,422 related to acquisition on 07/16/2021 of payroll management of the Government of the State of Minas Gerais.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.55 f) Share-based payment ITAÚ UNIBANCO HOLDING and its subsidiaries have share-based payment plans aimed at involving its management members and employees in the medium and long term corporate development process. The grant of these benefits is only made in years in which there are sufficient profits to permit the distribution of mandatory dividends, limiting dilution to 0.5% of the total shares held by the controlling and minority stockholders at the balance sheet date. These programs are settled through the delivery of ITUB4 treasury shares to stockholders. l – Partner Plan The program enables employees and managers of ITAÚ UNIBANCO HOLDING to invest a percentage of their bonus to acquire shares and share-based instruments. There is a lockup period of from three to five years, counted from the initial investment date, and the shares are thus subject to market price variations. After complying with the preconditions outlined in the program, beneficiaries are entitled to receive shares as consideration, in accordance with the number of shares indicated in the 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 remuneration grant date. The fair value of the consideration in shares is the market price at the grant date, less expected dividends. 01/01 to 12/31/2021 01/01 to 12/31/2020 Partner Plan (Note 9f) (127) (241) Share-based plan (370) (489) Total (497) (730) Expenses on share-based payment plans are presented in the table below: Change in the Partner Program 01/01 to 12/31/2021 01/01 to 12/31/2020 Quantity Quantity Opening balance 36,291,760 39,305,211 New (1) 14,583,318 10,488,126 Delivered (11,652,700) (11,408,109) Cancelled (2,278,382) (2,093,468) Closing balance 36,943,996 36,291,760 Weighted average of remaining contractual life (years) 1.80 1.69 Market value weighted average (R$) 16.71 23.37 (1) As a result of the reduction of the minority interest in XP Inc. and subsequent merger of XPart S.A.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.59 The methods and assumptions used to estimate the fair value are defined below: a) Central Bank of Brazil Deposits, Money market and Deposits received under securities repurchase agreements—The carrying amounts for these instruments are close to their fair values. b) Interbank deposits, Deposits, Funds from Acceptances and Issuance of Securities, Borrowings and Onlending and Subordinate Debts – They are calculated by discounting estimated cash flows at market interest rates. c) Securities and Derivatives Financial instruments—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, it is necessary to adopt present value estimates and other techniques to establish their fair value. In the absence of prices quoted by the Brazilian Association of Financial and Capital Markets Entities (ANBIMA), the fair values of government securities are calculated by discounting estimated cash flows at market interest rates, as well as corporate securities. d) Loan, lease and other credit 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 was determined by discounting estimated cash flows, at interest rates applicable to similar loans. For the majority of loans at floating rates, the carrying amount was considered to be close to their market value. The fair value of loan and lease operations not overdue was calculated by discounting the expected payments of principal and interest to maturity. The fair value of overdue loan and lease transactions was 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 knowledge of the individual debtor. Trading securities and Available for sale securities Level 1: Securities 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 other countries, shares, debentures with price published by ANBIMA and other securities traded in an active market. The following table summarizes the book values and estimated fair values for financial instruments: Book value Fair value Book value Fair value (*) Assets Central Bank of Brazil Deposits (a) 104,592 104,592 90,059 90,059 Money market (a) 166,140 166,140 237,668 237,668 Voluntary investments with the Central Bank of Brazil (a) 5,800 5,800 — Interbank deposits (b) 69,661 69,831 55,553 55,751 Trading securities (c) 121,460 121,460 167,625 167,625 Available for sale securities (c) 154,375 154,375 197,779 197,779 Held to maturity securities (c) 140,956 139,884 42,677 45,207 Derivatives financial instruments (c) 68,881 68,881 76,104 76,104 Loan, lease and other credit operations (d) 819,993 821,102 711,441 719,712 (Provision for loan losses) (44,198) (44,198) (47,967) (47,967) Liabilities Deposits (b) 860,024 859,929 814,689 814,644 Deposits received under securities repurchase agreements (a) 271,104 271,104 285,680 285,680 Funds from acceptances and issuance of securities (b) 143,138 143,057 136,638 136,698 Borrowings and onlending (b) 97,005 97,041 83,200 83,271 Derivatives financial instruments (c) 63,974 63,974 79,620 79,620 Subordinated debts (b) 75,036 75,707 74,916 77,097 Allowance for financial guarantees provided and loan commitments 4,784 4,784 4,250 4,250 (*) In the period, the result of Derivative Financial Instruments, as well as Adjustment to Fair Value of Securities (particularly private securities) had their amounts affected by oscillations of rates and other market variables arising from the impact of the COVID-19 pandemic on the macroeconomic scenario in the period (Note 20d). 12/31/2021 12/31/2020 Note 15 – Fair value of financial instruments In cases where market prices are not available, fair values are based on estimates using discounted cash flows or other valuation techniques. These techniques are significantly affected by the assumptions adopted, including the discount rate and estimate of future cash flows. The estimated fair value obtained through these techniques cannot be substantiated by comparison with independent markets and, in many cases, cannot be achieved on immediate settlement of the instrument.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.60 Level 2: Bonds, securities and derivatives 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 traded over-the-counter, certain Brazilian government bonds, debentures and other private securities whose credit component effect is not considered relevant, are at this level. Level 3: Bonds, securities and derivatives for which pricing inputs are generated by statistical and mathematical models. Debentures and other private 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. All the above methods may result in a fair value that is not indicative of the net realizable value or future fair values.

The models are documented, submitted to validation by an independent area and approved by a specific committee. The daily process of price capture, calculation and disclosure is 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 fixed-income assets.

Significant unobservable inputs used for measurement of the fair value of instruments classified in Level 3 are: interest rates, underlying asset prices and volatility. Significant variations in any of these inputs separately may give rise to substantial changes in the fair value. The table below shows the sensitivity of these fair values in scenarios of changes of interest rates or, asset prices, or in scenarios with varying shocks to prices and volatilities for nonlinear assets: 12/31/2021 12/31/2020 Scenarios Impacts Impacts Market risk factor groups Scenario I: Based on reasonably possible changes in assumptions of 5 percentage points on prices and 25 percentage points on the volatility level, both up and down, taking the largest losses resulting in each scenario. Scenario II: Based on reasonably possible changes in assumptions of 10 percentage points on prices and 25 percentage points on the volatility level, both up and down, taking the largest losses resulting in each scenario. The following scenarios are used to measure sensitivity: Based on reasonably possible changes in assumptions 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. Interest rate Commodities, Index and Shares Nonlinear Based on reasonably possible changes in assumptions 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.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.64 Note 17 – Post-employment benefits ITAÚ UNIBANCO HOLDING PRUDENTIAL, through its subsidiaries, sponsors retirement plans to its employees. Retirement plans are managed by Closed-end Private Pension Entities (EFPC) and are closed to new adhesions. These entities have an independent structure and manage their plans according to the characteristics of their regulations. There are three types of retirement plans: • Defined Benefit Plans (BD): plans which scheduled benefits have their value established in advance, based on salaries and/or length of service of employees, and its cost is actuarially determined; • Defined Contribution Plans (CD): are those plans 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; and • 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 accumulated balance by the participant on the retirement date. Below is a list of benefit plans and their modalities: Entity Benefit Plan Modality Fundação Itaú Unibanco – Previdência Complementar—FIU Supplementary Retirement Plan Defined Benefit Supplementary Retirement Plan – Flexible Premium Annuity Franprev Benefit Plan 002 Benefit Plan Prebeg Benefit Plan UBB PREV Defined Benefit Plan Benefit Plan II Itaulam Basic Plan Itaucard Defined Benefit Plan Itaú Unibanco Main Retirement Plan Itaubanco Defined Contribution Plan Itaubank Retirement Plan Defined Contribution Redecard Pension Plan Unibanco Pension Plan – Intelligent Future Variable Contribution Itaulam Supplementary Plan Itaucard Variable Contribution Plan Itaú Unibanco Supplementary Retirement Plan FUNBEP – Fundo de Pensão Multipatrocinado Benefit Plan l Defined Benefit Benefit Plan ll Variable Contribution 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 participants’ accounts, according to the respective benefit plan regulations.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.65 b) Risk Management The EFPCs sponsored by ITAÚ UNIBANCO HOLDING are regulated by the National Council for Complementary Pension (CNPC) and PREVIC, has an Executive Board, Advisory and Tax Councils. Benefits offered have long-term characteristics and the main factors involved in the management and measurement of their risks are financial risk, inflation risk and demographic risk. - Financial Risk – the actuarial liability of the plan is calculated by adopting a discount rate, which may differ from rates earned in investments. If real income from plan investments is lower than yield expected, this may give rise to a deficit. To mitigate this risk and assure the capacity to pay long-term benefits, the plans have a significant percentage of fixed-income securities pegged to the plan commitments, aiming at minimizing volatility and risk of mismatch between assets and liabilities. Additionally, adherence tests are carried out in financial assumptions to ensure their adequacy to obligations of respective plans. - Inflation risk – a large part of liabilities is pegged to inflation risk, making actuarial liabilities sensitive to 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 the EFPCs that manage them, actuarial liabilities of plans use discount rate adherent to its asset portfolio and income and expense flows, according to a study prepared by an independent 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 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. 12/31/2021 12/31/2020 Mortality table (1) AT-2000 AT-2000 Discount rate (2) 9.46% p.a. 7.64% p.a.

Retired plans sponsored by foreign subsidiaries—Banco Itaú (Suisse) S.A., Itaú CorpBanca Colombia S.A.—are structured as Defined Benefit modality and adopt actual assumptions adequate to masses of participants and the economic scenario of each country. a) Main Actuarial Assumptions Actuarial assumptions of demographic and financial nature should reflect the best estimated about the variables that determine the post-employment benefit obligations. The most relevant demographic assumption comprise of mortality table and the most relevant financial assumptions include: discount rate and inflation.

Particularly in other post-employment benefits, there is medical inflation risk associated to increase in medical costs above expectation. To mitigate this risk, the same financial risks mitigation strategies are used.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.69 Note 19 – Risk, Capital Management and Fixed Assets Limits a) Corporate Governance ITAÚ UNIBANCO HOLDING CONSOLIDATED invests in robust risk management processes and capital management that are the basis for its strategic decisions to ensure business sustainability and maximize shareholder value creation. These processes are aligned with the guidelines of the Board of Directors and Executive which, through collegiate bodies, define the global objectives expressed as targets and limits for the business units that manage risk. Control and capital management units, in turn, support ITAÚ UNIBANCO HOLDING CONSOLIDATED’s management by monitoring and analyzing risk and capital. The Board of Directors is the main body responsible for establishing guidelines, policies and approval levels for risk and capital management. The Risk and Capital Management Committee (CGRC), in turn, is responsible for supporting the Board of Directors in managing capital and risk. At the executive level, collegiate bodies, presided over by the Chief Executive Officer (CEO) of ITAÚ UNIBANCO HOLDING CONSOLIDATED, are responsible for capital and risk management, and their decisions are monitored by the CGRC.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.70 Based on this statement, five dimensions have been defined (Capitalization, Liquidity, Composition of Earnings, Operating Risk and Reputation). Each dimension consists of a set of metrics associated with the main risks involved, combining supplementary measurement methods, to give a comprehensive vision of our exposure. The Board of Directors is responsible for approving guidelines and limits for risk appetite, with the support of CGRC and the CRO (Chief Risk Officer). The limits for risk appetite are monitored regularly and reported to risk committees and to the Board of Directors, which will oversee the preventive measures to be taken to ensure that exposure is aligned with the strategies of ITAÚ UNIBANCO HOLDING CONSOLIDATED. Foremost among BACEN’s requirements for proper risk and capital management are the Risk Appetite Statement (RAS) and the implementation of a continuous, integrated risk management structure, the stress test program, the establishment of a Risk Committee, and the nomination at BACEN of a Chief Risk Officer (CRO), with roles and responsibilities assigned, and requirements for independence. Risk appetite, risk management and guidelines for employees of ITAÚ UNIBANCO HOLDING CONSOLIDATED for routine decision-making purposes are based on: • Sustainability and customer satisfaction: ITAÚ UNIBANCO HOLDING CONSOLIDATED’s vision is to be the leading bank in sustainable performance and customer satisfaction and, accordingly, we are committed to creating shared value for staff, customers, stockholders and society, ensuring the continuity of the business. ITAÚ UNIBANCO HOLDING CONSOLIDATED is committed to doing business that is good both for the customer and the institution itself; • Risk culture: ITAÚ UNIBANCO HOLDING CONSOLIDATED’s risk culture goes beyond policies, procedures or processes, reinforcing 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; • Risk pricing: ITAÚ UNIBANCO HOLDING CONSOLIDATED’s operates and assumes risks in business that it knows and understands, avoids the ones that are unknown or that do not provide competitive advantages, and carefully assesses risk-return ratios; • Diversification: ITAÚ UNIBANCO HOLDING CONSOLIDATED has little appetite for volatility in earnings, and it therefore operates with a diverse base of customers, products and business, seeking to diversify risks and giving priority to lower risk business; • Operational excellence: It is the wish of ITAÚ UNIBANCO HOLDING CONSOLIDATED to be an agile bank, with a robust and stable infrastructure enabling us to offer top quality services; • Ethics and respect for regulation: for ITAÚ UNIBANCO HOLDING CONSOLIDATED, ethics is nonnegotiable, and it therefore promotes an institutional environment of integrity, encouraging staff to cultivate ethics in relationships and business and to respect the rules, thus caring for the institution’s reputation. ITAÚ UNIBANCO HOLDING CONSOLIDATED has various ways of disseminating risk culture, based on four principles: conscious risk-taking, discussion of the risks the institution faces, the corresponding action taken, and the responsibility of everyone for managing risk. These principles serve as a basis for ITAÚ UNIBANCO HOLDING CONSOLIDATED’s guidelines, helping employees to conscientiously understand, identify, measure, manage and mitigate risks. 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.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.71 The credit policy of ITAÚ UNIBANCO HOLDING CONSOLIDATED is based on internal criteria such as: classification of customers, portfolio performance and changes, default levels, rate of return and economic capital allocated, and external factors such as interest rates, market default indicators, inflation, changes in consumption, and so on. In compliance with CMN Resolution 4,557, of February 23, 2017, the document “Public Access Report – Credit Risk”, which includes the guidelines established by our credit risk control policy, can be viewed at www.itau.com.br/investor-relations, in the section Itaú Unibanco, under Corporate Governance, Regulations and Policies, Reports. II—Market risk The possibility of incurring financial losses from changes in the market value of positions held by a financial institution, including the risks of transactions subject to fluctuations in currency rates, interest rates, share prices, price indexes and commodity prices, as set forth by CMN. Price Indexes are also treated as a risk factor group. Market risk is controlled by an area independent from the business areas, which is responsible for the daily activities of (i) risk measurement and assessment, (ii) monitoring of stress scenarios, limits and alerts, (iii) application, analysis and testing of stress scenarios, (iv) risk reporting to those responsible within the business areas, in compliance with the governance of ITAÚ UNIBANCO HOLDING CONSOLIDATED, (v) monitoring of actions required to adjust positions and risk levels to make them realistic, and (vi) providing support for the safe launch of new financial products. The market risk structure categorizes transactions as part of either the banking portfolio or the trading portfolio, in accordance with general criteria established by CMN Resolution 4,557, of February 23, 2017, and BACEN Circular 3,354, of June 27, 2007. 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: metric used to revise positions, should losses accumulated in a fixed period reach a certain level; • Concentration: cumulative exposure of a certain financial instrument or risk factor, calculated at fair value (MtM – Mark to Market); and • Stressed VaR: statistical metric derived from the VaR calculation, with the purpose is 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: • Î”EVE (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; • Î”NII (Delta Net Interest Income): difference between the result of financial intermediation of instruments subject to IRRBB in a base scenario and the result of financial intermediation 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 fair 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; and

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.72 ï,· Sensitivity to Sundry Risk Factors (Greeks): partial derivatives of an option portfolio in relation to the prices of underlying assets, implied volatilities, interest rates and time. In order to operate within the defined limits, ITAÚ UNIBANCO HOLDING CONSOLIDATED hedges transactions with customers and proprietary positions, including its foreign investments. Derivatives are commonly used for these hedging activities, which can be either accounting or economic hedges, both governed by the institutional polices of ITAÚ UNIBANCO HOLDING CONSOLIDATED (Note 5 – Securities and derivative financial instruments). The structure of limits and alerts obeys 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 ITAU UNIBANCO HOLDING CONSOLIDATED’s appetite for risk. The consumption of market risk limits is monitored and disclosed daily through exposure and sensitivity maps. The market risk area analyzes and controls the adherence of these exposures to limits and alerts and reports them timely to the Treasury desks and other structures foreseen in the governance. ITAÚ UNIBANCO HOLDING CONSOLIDATED uses proprietary systems to measure the consolidated market risk. The processing of these systems occurs in a high-availability access-controlled environment, which has data storage and recovery processes and an infrastructure that ensures business continuity in contingency (disaster recovery) situations. At 12/31/2021, ITAÚ UNIBANCO HOLDING CONSOLIDATED presented a Total VaR of R$ 696, an increase in relation to prior year (R$ 223 at 12/31/2020) due to higher exposure and higher volatility in interest rates. The document “Public Access Report – Market Risk Management and Control Policy“, which includes which includes our internal policy guidelines for market risk control, is not an integral part of the financial statements, but can be viewed at www.itau.com.br/investor-relations, in the section Itaú Unibanco, Corporate Governance, Regulations and Policies, Reports. III – Liquidity risk The possibility that the institution may be unable to efficiently meet its expected and unexpected obligations, both current and future, including those arising from guarantees issued, without affecting its daily operations and without incurring significant losses. Liquidity risk is controlled by an area independent from the business area and responsible for establishing the reserve composition, estimating the cash flow and exposure to liquidity risk in different time horizons, and for monitoring the minimum limits to absorb losses in stress scenarios for each country where ITAÚ UNIBANCO HOLDING CONSOLIDATED operates. All activities are subject to verification by independent validation, internal control and audit areas. The document Public Access Report—Liquidity Risk Management and Control Policy, which includes our internal policy guidelines for liquidity risk control, is not an integral part of the financial statements, but can be viewed on the website www.itau.com.br/investor-relations, in the section Itaú Unibanco, Corporate Governance, Regulations and Policies, Reports.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.73 IV – Operating risk Defined as the possibility of losses from failures, defects or shortcomings in internal processes, people or systems, or from external events impacting the realization of strategic, tactical or operational objectives. It includes the legal risk of inadequacies or defects in agreements signed by the institution, as well as sanctions for failing to comply with legal provisions and compensation to third parties for losses arising from the institution’s activities. The managers of executive areas use corporate methods developed and supplied by the internal controls, compliance and operating risk area. As part of governance of the risk management process, consolidated reports on risk monitoring, controls, action plans and operating losses are periodically presented to the business areas’ executives. In line with the principles of CMN Resolution 4,557, of February, 23, 2017, the document entitled “Public Access Report – Integrated Operational Risk Management and Internal Controls”, a summarized version of the institutional operating risk management policy, may be viewed on the website www.itau.com.br/investor-relations, in the section Itaú Unibanco, Corporate Governance, Regulations and Policies, Reports. V—Insurance, private pension and premium bonds risks The main risks related to Insurance, Private Pension and Premium Bonds portfolios are described below and defined in their respective chapters. • Underwriting risk: possibility of losses arising from insurance, pension plan and premium bonds operations contrary to the institution’s expectations of ITAÚ UNIBANCO HOLDING CONSOLIDATED, directly or indirectly associated with technical and actuarial bases adopted to calculate premiums, contributions and provisions; • Credit risk; • Market risk; • Liquidity risk; • Operating risk. These risks are managed independently, according to their special characteristics. VI—Emerging risks They are those with a potentially material impact on the business in the medium and long terms, but for which there are not enough elements yet for their complete assessment and mitigation due to the number of factors and impacts not yet totally known, such as technological alternatives in replacement of traditional banking services and the demographic transition of clients in contrast to technological innovations. Their causes can be originated by external events and result in the emergence of new risks or in the intensification of risks already monitored by ITAÚ UNIBANCO HOLDING CONSOLIDATED. The identification and monitoring of Emerging Risks are ensured by ITAÚ UNIBANCO HOLDING CONSOLIDATED’s governance, allowing these risks to be incorporated into risk management processes too. VII – Social and Environmental Risk and Climate Risk Social and Environmental risk is the possibility of losses due to exposure to social and/or environmental events related to the activities developed by the ITAÚ UNIBANCO HOLDING CONSOLIDATED. Social and environmental factors are considered relevant to the business of ITAÚ UNIBANCO HOLDING CONSOLIDATED, since they may affect the creation of shared value in the short, medium and long term. The Policy on Sustainability and Social and Environmental Responsibility (PRSA) establishes the guidelines, strategies and underlying principles for social and environmental risk management, based on institutional issues and addressing, through specific procedures, the most significant risks for the Institution’s operation.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.74 Actions to mitigate the Social and Environmental Risk are taken based on the mapping of processes, risks and controls, monitoring of new standards related to the theme and record 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 this risk at ITAÚ UNIBANCO HOLDING CONSOLIDATED. The management of social and environmental risk adopts the strategy of three defense lines: the first defense line (business areas) manages the risk in its daily activities, following the PRSA guidelines, specific processes, with the support of specialized assessment from dedicated technical teams located in Corporate Compliance, Credit Risk and Modeling, and Institutional Legal teams, that act on an integrated way in the management of all dimensions of the Social and Environmental Risk related to the conglomerate’s activities. As an example of the specific guidelines to manage this risk, business units count on the governance for approval of new products and services, which contemplates, in its assessments, the Social and Environmental Risk, ensuring the compliance with this requirement in new products approved by the Institution, as well as specific social and environmental procedures for the Institution’s operation (stockholders’ equity, branch infrastructure and technology), suppliers, credit, investments and key controls. The second line of defense, in turn, is represented by the Credit Risk and Modeling, by Internal Controls, as well as Compliance, through the Corporate Social and Environmental Risk Management, which supports and ensures the governance of the first line’s activities. The third line of defense composed of the Internal Audit, acts on an independent manner, mapping and assessing risk management, controls and governance. Governance also counts on the Social and Environmental Risk Committee, whose main responsibility is to assess and deliberate about institutional and strategic matters, as well as to resolve on products, operations, and services, among others involving the Social and Environmental Risk, including Climate Risk. 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. Considering its relevance, climate risk has become one of the main priorities for ITAÚ UNIBANCO HOLDING CONSOLIDATED, which supports the Task Force on Climate-related Financial Disclosures (TCFD) and it is committed to its implementation of its recommendations. With this purpose, ITAÚ UNIBANCO HOLDING CONSOLIDATED is strengthening the governance and strategy related to Climate Risk and developing tools and methodologies to assess and manage these risks. ITAÚ UNIBANCO HOLDING CONSOLIDATED measures the sensitivity of the credit portfolio to climate risks by applying the Climate Risk Sensitivity Assessment Tool, developed by Febraban. The tool combines relevance and proportionality criteria to identify the sectors and clients within the portfolio that are more sensitive to climate risks, considering physical and transition risks. The sectors with the highest probability of suffering financial impacts from climate change for ITAÚ UNIBANCO HOLDING CONSOLIDATED are: energy, transport, materials and construction, agriculture, food and forestry products. Further details on environmental and social risk, which is not an integral part of the financial statements, can be viewed at www.itau.com.br/investor-relations, section Results and Reports, Regulatory Reports, Pillar 3 and Global Systemically Important Banks / Risk and Capital Management – Pillar 3. c) Capital management governance ITAÚ UNIBANCO HOLDING CONSOLIDATED is subject to the regulations of BACEN, which determines minimum capital requirements, procedures to obtain information to assess the global systemic importance of banks, fixed asset limits, loan limits and accounting practices, and requires banks to conform to the regulations based on the Basel Accord for capital adequacy. Additionally, CNSP and SUSEP issue regulations on capital requirements that affect our insurance operations and private pension and premium bonds plans. The capital statements were prepared in accordance with BACEN’s regulatory requirements and with internationally accepted minimum requirements according to the Bank for International Settlements (BIS).

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.75 I – Composition and Capital Adequacy The Board of Directors is the body responsible for approving the institutional capital management policy and guidelines for the capitalization level of ITAÚ UNIBANCO HOLDING CONSOLIDATED. The Board is also responsible for the full approval of the ICAAP (Internal Capital Adequacy Assessment Process) report, the purpose of which is to assess the capital adequacy of ITAÚ UNIBANCO HOLDING CONSOLIDATED. The result of the last ICAAP, which comprises stress tests – which was dated December 2020 – indicated that ITAÚ UNIBANCO HOLDING CONSOLIDATED has, in addition to capital to cover all material risks, a significant capital surplus, thus assuring the solidity of the institution’s equity position. In order to ensure that ITAÚ UNIBANCO HOLDING CONSOLIDATED is sound and has the capital needed to support business growth, the institution maintains PR levels above the minimum level required to face risks, as demonstrated by the Common Equity, Tier I Capital and Basel ratios. As of December 31, 2021 the amount of perpetual subordinated debt that makes up Tier I capital is R$ 18,167 (R$17,078 as of December 31, 2020) and the amount of subordinated debt that makes up Tier II capital is R$19,469 (R$14,024 as of December 31, 2020). The Basel Ratio reached 14.7% on December 31, 2021, with an increase of 0.2 percentage point as compared to 12/31/2020. The main change was the income for the period offset by the increase in loan portfolio. Additionally, ITAÚ UNIBANCO HOLDING CONSOLIDATED has a surplus over the required minimum Referential Equity of R$ 77,490 (R$ 67,867 at 12/31/2020), well above the ACP of R$ 34,615 (R$ 23,450 at 12/31/2020), generously covered by available capital. The fixed assets ratio shows the commitment percentage of adjusted Referential Equity with adjusted permanent assets. ITAÚ UNIBANCO HOLDING CONSOLIDATED falls within the maximum limit of 50% of adjusted PR, established by BACEN. At 12/31/2021, fixed assets ratio reached 16.9% (24.0% at 12/31/2020), showing a surplus of R$ 56,280 (R$ 39,274 at 12/31/2020).

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.76 II—Risk-Weighted Assets (RWA) For calculating minimum capital requirements, RWA must be obtained by taking the sum of the following risk exposures: RWA = RWACPAD + RWAMINT + RWAOPAD • portion related to exposures to credit risk, calculated using the standardized approach; • portion related to capital required for market risk, composed of the maximum between the internal model and 80% of the standardized model, regulated by BACEN Circulars nº 3,646 and nº 3,674; • = portion related to capital required for operational risk, calculated based on the standardized approach. a b 12/31/2021 12/31/2020 Credit Risk standardized approach 1,044,344 921,934 Credit risk (excluding counterparty credit risk) 922,824 778,153 Counterparty credit risk (CCR) 42,898 45,674 Of which: standardized approach for counterparty credit risk (SA-CCR) 27,616 27,119 Of which: other CCR 15,282 18,555 Credit valuation adjustment (CVA) 8,102 5,960 Equity investments in funds—look-through approach 5,001 4,897 Equity investments in funds—mandate-based approach 95 623 Equity investments in funds—fall-back approach 824 716 Securitisation exposures—standardized approach 2,195 1,506 Amounts below the thresholds for deduction 62,405 84,405 Market Risk 22,985 27,481 Of which: standardized approach (RWAMPAD) 28,731 34,351 Of which: internal models approach (RWAMINT) 14,751 22,362 Operational Risk 86,512 92,792 Total 1,153,841 1,042,207 RWA

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.77 III—Recovery Plan In response to the latest international crises, the Central Bank published Resolution No. 4,502, which requires the development of a Recovery Plan by financial institutions within Segment 1, with total exposure to GDP of more than 10%. This plan aims to reestablish adequate levels of capital and liquidity above regulatory operating limits in the face of severe systemic or idiosyncratic stress shocks. In this way, each institution could preserve its financial viability while also minimizing the impact on the National Financial System. More details on the Recovery Plan can be viewed at www.itau.com.br/investor-relations, section Results and Reports, Regulatory Reports, Pillar 3 and Risk and Capital Management – Pillar 3. IV—Stress testing The stress test is a process of simulating extreme economic and market conditions on ITAÚ UNIBANCO HOLDING CONSOLIDATED’s results, liquidity and capital. The institution has been carrying out this test in order to assess its solvency in plausible scenarios of crisis, as well as to identify areas that are more susceptible to the impact of stress that may be the subject of risk mitigation. For the purposes of the test, the economic research area estimates macroeconomic variables for each stress scenario. The elaboration of stress scenarios considers the qualitative analysis of the Brazilian and the global conjuncture, historical and hypothetical elements, short and long term risks, among other aspects, as defined in CMN Resolution 4,557. In this process, the main potential risks to the economy are assessed based on the judgment of the bank’s team of economists, endorsed by the Chief Economist of ITAÚ UNIBANCO HOLDING CONSOLIDATED and approved by the Board of Directors. Projections for the macroeconomic variables (such as GDP, basic interest rate, exchange rates and inflation) and for variables in the credit market (such as raisings, lending, rates of default, margins and charges) used are based on exogenous shocks or through use of models validated by an independent area. Then, the stress scenarios adopted are used to influence the budgeted result and balance sheet. In addition to the scenario analysis methodology, sensitivity analysis and the Reverse Stress Test are also used. ITAÚ UNIBANCO HOLDING CONSOLIDATED uses the simulations to manage its portfolio risks, considering Brazil (segregated into wholesale and retail) and External Units, from which the risk-weighted assets and the capital and liquidity ratios are derived. The stress test is also an integral part of the ICAAP, the main purpose of which is to assess whether, even in severely adverse situations, the institution would have adequate levels of capital and liquidity, without any impact on the development of its activities. This information enables potential offenders to the business to be identified and provides support for the strategic decisions of the Board of Directors, the budgeting and risk management process, as well as serving as an input for the institution’s risk appetite metrics. V – Leverage Ratio The Leverage Ratio is defined as the ratio of Capital Tier I to Total Exposure, calculated pursuant to BACEN Circular 3,748, of February 27, 2015. The purpose of this ratio is to be a simple measure of leverage not sensitive to risk, thus it does not consider weighting or mitigation factors. According to instructions in BACEN Circular Letter 3,706, of May 5, 2015, ITAÚ UNIBANCO HOLDING CONSOLIDATED has sent the Leverage Ratio monthly to BACEN, whose minimum requirement is 3%.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.78 Note 20 – Supplementary information a) Insurance policy—ITAÚ UNIBANCO HOLDING PRUDENTIAL, despite the reduced risk exposure due to the low physical concentration of its assets, has a policy of insuring valuables and assets at amounts considered sufficient to cover possible losses. c) Agreements for offsetting and settlement of liabilities within the scope of the National Financial System Offset agreements are in force in relation to derivative contracts, as well as agreements for the offsetting and settlement of receivables and payables pursuant to CMN Resolution 3,263, of February 24, 2005, the purpose of which is to enable the offsetting of credits and debits with the same counterparty, and where the maturity dates of receivables and payables can be brought forward to the date of an event of default by one of the parties or in the event of bankruptcy of the debtor. d) “Coronavirus” COVID-19 relief efforts ITAÚ UNIBANCO HOLDING PRUDENTIAL monitors the economic effects of this COVID-19 pandemic in Brazil and the other countries where it operates, which may adversely affect its Profit or Loss.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.79 viii) Law No. 14,148/21 which established the Emergency Program for the Recovery of the Events Sector (PERSE), which aims at creating conditions for the events sector to mitigate losses arising from the state of calamity and the Guarantee Program for Critical Sectors (PGSC), guaranteeing loan operations contracted within 180 days after the law becomes effective; and ix) BACEN Circular No. 3,990/20 and amendments made by BACEN Circular 3,992/20 which permits to carry out repurchase agreements in foreign currency by BACEN; ITAÚ UNIBANCO HOLDING PRUDENTIAL identified the following impacts on its results, as well as effects on estimates and critical judgments for the preparation of the Consolidated Financial Statements: (a) increase in 2020 and 2021 in loan and financing operations, especially for micro, small and mediumsized companies due to the measures adopted for mitigation of the impacts of COVID-19 by the authorities with the creation of programs such as PESE, PRONAMPE, PEAC-FGI and CGPE, which balance in December 2021 is R$ 21,492. Through timely monitoring of credit standards and behavior of clients, ITAÚ UNIBANCO HOLDING PRUDENTIAL maintained the regularity of its operations, despite the adverse conditions, and helped clients in the sustainable search for their financial rebalancing; (b) with the purpose of treating indebtedness in a structured way and giving financial impetus to clients, initiatives were established that allowed the extension of grace periods, terms and better interest rate conditions for individuals, and micro and small business clients. In December 2021 this portfolio amount to R$ 31.1 billion. In March 2020, the Program 60+ was established, which, among other measures, allowed a 60-day grace period for defaulting agreements and in mid-April the Travessia (Crossing) Program. Travessia allowed the extension of grace periods between 120 and 180 days and terms of operations between 5 and 6 years, respectively, for individual and micro and small companies clients, under better interest rate conditions; (c) 5.4% decrease at the current period in applications of renegotiation and extension of terms for loan operations as the economic situation changed. In December 2021, 80.1% of the loan operations portfolio generated by means of these initiatives was current, 1.8% was in a grace period, 6.5% was past due between 15 and 90 days and 11.6% was past due for over 90 days; (d) the allowance for loan losses in the amount of R$ 49,482 was affected due to the level of risk and default, due to the changes in the financial perspectives of clients and the visible deterioration of macroeconomic variables. To fully reflect the risk of its loan operations, ITAÚ UNIBANCO HOLDING PRUDENTIAL adopts the expected loss model for provisioning of operations since the moment they are granted and it is periodically updated according to the macroeconomic variables and circumstances of the client, and in 2020, in view of the pandemic, a weighting in the economic scenarios was added. In December 2021, the level of coverage of provisions in the loan portfolio of ITAÚ UNIBANCO HOLDING PRUDENTIAL accounted for 241% as compared to 320% in December 2020. Specifically for the expected loss of operations that have not shown any signs of deterioration so far (default or downgrading of the client’s rating), provisioning presented a decrease of 16.9% at the current period. The credit risk governance allowed ITAÚ UNIBANCO HOLDING PRUDENTIAL a quick response for monitoring the impacts of the COVID-19 pandemic on the loan portfolio, permitting quick access to the information needed for discussions and actions of the crisis management daily forums; (e) the mark-to-market component of the securities portfolio was -2.0% in the first quarter of 2020, partially due to rate fluctuations and high price volatility in the markets in the beginning of the pandemic, influencing the measurement of items stated at fair value in their different levels. In subsequent periods, variations observed in the mark-to-market component are not necessarily related to the effects of the pandemic; (f) due to the COVID-19 pandemic, during 2020, the instability in the variable income market was noted causing a migration to fixed income instruments with liquidity. This movement resulted in the increase in the Bank Deposit Certificates portfolio; however, over 2021, variation in the portfolio was noted, with changes not necessarily related to the effects of the pandemic. With the purpose of mitigating the system’s liquidity risk, BACEN made available in 2020 to financial institutions credit lines through repurchase agreements in foreign currency and purchase of financial bills with guarantee, and operations in the total amount of R$ 30,547 were contracted during the period of life of these lines; and (g) increase in the recognition of deferred income tax and social contribution in 2020 due to the greater volume of deductible temporary differences recorded for the period. The pandemic reduced the projections of taxable income, however, it was not responsible for the generation of tax loss and social contribution loss carryforwards in ITAÚ UNIBANCO HOLDING PRUDENTIAL. In the period, there were no significant impacts of the pandemic in the recognition of deferred income tax and social contribution in ITAÚ UNIBANCO HOLDING PRUDENTIAL.

Itaú Unibanco Holding S.A. – Prudencial Financial Statements – December 31, 2021 4.80 There was a reduction in the face-to-face service staff and an increase in the spacing between people in call centers to reduce the circulation of people and the possibilities of contagion. The average number of people circulating in administrative centers was reduced, since they started to work remotely. Employees in the central management, service centers and digital branches are substantially working from home. It should be noted that despite the aforementioned measures, ITAÚ UNIBANCO HOLDING PRUDENTIAL maintains its operating activities. In order to reduce the effects of the crisis and ensure the employee’s health and safety, self-declaration was encouraged for employees who consider themselves at risk and those who cannot work remotely were put on vacation. In 2020, with the purpose of supporting those who possibly had additional expenses due to the current crisis, the 13th salary was advanced in full. Additionally, a process of communication and transparency with employees was established through e-mails, internal employee’s portal and periodic videos prepared by our Chief Executive Officer communicating news related to COVID-19. At the branches, masks were delivered to all employees who work in customer service, acrylic protections were implemented and cleaning protocols were reviewed. The adaptation of ITAÚ UNIBANCO HOLDING PRUDENTIAL in the crisis is the result not only of investments in technology, which allows for these virtual interactions, but also of investments in flexibility in the work environment, such as work from home, communities integrated between different areas of the bank and new layouts in the administrative centers that promote the employees’ mobility. In 2020, ITAÚ UNIBANCO HOLDING CONSOLIDATED created the initiative “Todos pela Saúde” (All for Health) from the donation of R$ 1 billion, with the purpose of combating the new Coronavirus and its effects on Brazilian society. “Todos Pela Saúde” is conducted based on four axes: Informing, Protecting, Caring, and Resuming.

The activities to be developed include both research funding and genomic (or metagenomic) surveys, in addition to the training of field epidemiologists.

4 Corporativo | Interno In preparing the consolidated financial statements, management is responsible for assessing the Bank’s ability to continue as going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Bank or to cease operations, or has no realistic alternative but to do so. Those charged with governance in the Bank are responsible for overseeing the financial reporting process for the preparation of the consolidated financial statements of the Prudential Conglomerate. Auditor’s responsibilities for the audit of the consolidated financial statements Our objectives are to obtain reasonable assurance about whether the consolidated financial statements of the Prudential Conglomerate, prepared in accordance with Resolution 4,280 of CMN, and supplementary regulations of BACEN, as a whole, are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that the audit conducted in accordance with the Brazilian and International Standards on Auditing will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements. As part of an audit in accordance with Brazilian and International Standards on Auditing, taking into consideration the NBC TA 800 (Special Conditions – Audit Financial Statements in accordance with special purpose accounting conceptual structures), we exercise professional judgment and maintain professional skepticism throughout the audit. We also: • Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. • Obtain an understanding of internal controls relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the internal controls of the Bank and its subsidiaries. • Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management. • Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Bank’s ability to continue as going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Bank to cease to continue as going concern.

5 Corporativo | Interno • Evaluate the overall presentation, structure and content of the consolidated financial statements, including the disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation. • Obtain sufficient appropriate audit evidence regarding the financial information of associates and joint ventures to express an opinion on the Bank’s financial statements. We are responsible for the direction, supervision and performance of the audit, considering these investees. We remain solely responsible for our audit opinion. We communicate with those charged with governance regarding, among other things, the scope and timing of planned audit engagements and significant audit findings, including significant deficiencies in internal controls that may have been identified during our engagements.
