(2) Includes banking services fees, income related to insurance and private pension operations before claim and selling expenses and other income. Three-month period ended March 31, 2020 compared to three-month period ended March 31, 2019. Net income attributable to the owners of the parent company decreased by 48.7% to R$3,459 million for the three-month period ended March 31, 2020 from R$6,747 million for the same period of 2019. This result is mainly due to the 173.9% increase in expected losses from financial assets and claims. This was partially offset by the 5.8% increase in non-interest income. These line items are further described below: • Net interest income decreased by 85.4% for the three-month period ended March 31, 2020 7 OPERATING AND FINANCIAL REVIEW AND PROSPECTS The following discussion should be read in conjunction with our unaudited interim consolidated financial statements and accompanying notes and other financial information included elsewhere in this Form 6-K and the description of our business in “Item 4.

(2) Includes banking services fees, income related to insurance and private pension operations before claim and selling expenses and other income. Three-month period ended March 31, 2020 compared to three-month period ended March 31, 2019. Net income attributable to the owners of the parent company decreased by 48.7% to R$3,459 million for the three-month period ended March 31, 2020 from R$6,747 million for the same period of 2019. This result is mainly due to the 173.9% increase in expected losses from financial assets and claims. This was partially offset by the 5.8% increase in non-interest income. These line items are further described below: • Net interest income decreased by 85.4% for the three-month period ended March 31, 2020 7

compared to the same period of 2019, mainly due to the adjustment to the fair value of financial assets and liabilities. The result of exchange rate fluctuations on our investments abroad is non-taxable, whereas revenues from our hedging instruments are taxable. Accordingly, the depreciation of the Brazilian real against foreign currencies, especially the U.S. dollar, generates gains on our hedging instruments abroad. Conversely, the appreciation of the real against foreign currencies, generates losses on our hedging instruments abroad. This affects our tax expenses allocated in the line items “current and deferred income and social contribution taxes” and “other operating income (expenses).” The nominal depreciation of the real against the U.S. dollar was 33.4% for the three-month period ended March 31, 2020 compared to 17.2% for the same period of 2019. The fiscal effect on the hedging instruments for our investments abroad resulted in a gain of R$14,428 million for the three-month period ended March 31, 2020, compared to a gain of R$110 million for the same period of 2019. As a result, disregarding the fiscal effect on the hedging instruments for our investments abroad mentioned above, net interest income decreased by R$630 million for the three-month period ended March 31, 2020 compared to the same period of 2019. o Interest and similar income of financial assets at amortized cost and at fair value through other comprehensive income increased by 26.2% for the three-month period ended March 31, 2020 compared to the same period of 2019, mainly due to the growth of our loan portfolio particularly our micro/small and medium businesses portfolio (10.1%) and corporate portfolio (21.5%) in Brazil as of March 31, 2020 compared to December 31, 2019. This result was partially offset by lower interest rates and lower spreads on credit products, in part due to Resolution No. 4,765, which caps interest rates for checking account overdraft facilities up to 8% per month. CMN Resolution No. 4,765 came into effect on January 6, 2020. o Interest and similar expenses increased by 58.9% for the three-month period ended March 31, 2020 compared to the same period of 2019, mainly due to increased expenses from interbank market funds, mainly as a result of an increase of R$19,429 million in the balance of import and export financing, which was affected by exchange rate fluctuations. This result was partially offset by financial expenses from technical provisions for insurance and private pensions plans, which amounted to a gain of R$4,807 million for the three-month period ended March 31, 2020 compared to an expense of R$3,912 million for the same period of 2019, as a result of the devaluation of investment fund quotas and consequent effect on the private pension plans. The gain on financial expenses from technical provisions for insurance and private pension plans was almost entirely offset by a loss on financial income related to the same technical provisions. Please see “Note 21 – Interest and Similar Income and Expense and Net Gain (Loss) on Investment Securities and Derivatives” to our unaudited interim consolidated financial statements for further details on Net interest and similar income. 8 compared to the same period of 2019, mainly due to the adjustment to the fair value of financial assets and liabilities.

This result was partially offset by financial expenses from technical provisions for insurance and private pensions plans, which amounted to a gain of R$4,807 million for the three-month period ended March 31, 2020 compared to an expense of R$3,912 million for the same period of 2019, as a result of the devaluation of investment fund quotas and consequent effect on the private pension plans.

• Non-Interest Income increased by 5.8% to R$11,424 million for the three-month period ended March 31, 2020 compared to the same period of 2019. This increase was mainly due to an increase in: (i) income from funds management fees of 45.0%, or R$524 million, for the three-month period ended March 31, 2020 compared to the same period of 2019, due to a 12.4% increase in the balance of assets under management; (ii) income from advisory and brokerage services of 123.4%, or R$427 million, for the three- month period ended March 31, 2020 compared to the same period of 2019, mainly due to increased activity in the capital markets; and (iii) income from current account services of 4.2%, or R$82 million, for the three-month period ended March 31, 2020 compared to the same period of 2019, mainly due to the increase in the number of current account holders and the greater number of payment transactions, although this result was partially offset by a greater number of fee exemptions granted to current account holders. These results were partially offset by lower revenues from acquiring business, particularly revenues from merchant discount rate, rental of equipment and prepayments. As of the second half of March 2020, the volume of credit and debit cards transactions decreased due to social distancing measures adopted in response to the COVID-19 pandemic. The following chart shows the main components of our banking service fees for the three- month periods ended March 31, 2020 and 2019: Please see “Note 22 – Commissions and Banking Fees” to our unaudited interim consolidated financial statements for further details on banking service fees. 9 • Non-Interest Income increased by 5.8% to R$11,424 million for the three-month period ended March 31, 2020 compared to the same period of 2019. This increase was mainly due to an increase in: (i) income from funds management fees of 45.0%, or R$524 million, for the three-month period ended March 31, 2020 compared to the same period of 2019, due to a 12.4% increase in the balance of assets under management; (ii) income from advisory and brokerage services of 123.4%, or R$427 million, for the three- month period ended March 31, 2020 compared to the same period of 2019, mainly due to increased activity in the capital markets; and (iii) income from current account services of 4.2%, or R$82 million, for the three-month period ended March 31, 2020 compared to the same period of 2019, mainly due to the increase in the number of current account holders and the greater number of payment transactions, although this result was partially offset by a greater number of fee exemptions granted to current account holders. These results were partially offset by lower revenues from acquiring business, particularly revenues from merchant discount rate, rental of equipment and prepayments. As of the second half of March 2020, the volume of credit and debit cards transactions decreased due to social distancing measures adopted in response to the COVID-19 pandemic. The following chart shows the main components of our banking service fees for the three- month periods ended March 31, 2020 and 2019: Please see “Note 22 – Commissions and Banking Fees” to our unaudited interim consolidated financial statements for further details on banking service fees. 9

• Expected Loss from Financial Assets and Claims increased by 173.9% for the three-month period ended March 31, 2020 compared to the same period of 2019, mainly due to an increase in expected loss with loan operations and lease operations of R$5,923 million for the three- month period ended March 31, 2020. This increase is related to the changes in the macroeconomic scenario and financial perspectives for individuals and companies as of the second half of March 2020, as a result of the COVID-19 pandemic. Please see “Note 10—Loan and lease operations portfolio” to our unaudited interim consolidated financial statements for further details on our loan and lease operations portfolio. o Non-performing loans: We calculate our 90-day non-performing loans ratio as the value of our 90-days non-performing loans to our loan portfolio. As of March 31, 2020, our 90-day NPL ratio was 3.5%, a decrease of 8 basis point compared to March 30, 2019, due to a 50 basis point decrease of the 90-day NPL ratio for our loans to companies portfolio This decrease was offset by a 50 basis point increase in the 90-day NPL ratio for our individuals loan portfolio, mainly due to an increase in higher risk loan portfolios in the product mix. We calculate our 15 to 90 days non-performing loans ratio as the value of our 15 to 90 days non-performing loans to our loan portfolio. The 15 to 90 days non-performing loans ratio is an indicator of early delinquency. As of March 31, 2020, our 15 to 90 days NPL ratio was 2.6% an increase of 13 basis point compared to March 31, 2019. Our 15 to 90-day NPL ratio of our companies loan portfolio increased 12 basis point, and our 15 to 90-day NPL ratio of our individuals loan portfolio increased 27 basis point, mainly due to an increase in higher risk loan portfolios in the product mix. The chart below shows a comparison of both NPL ratios for each quarter as of March 31, 2019 through to March 31, 2020: 10 • Expected Loss from Financial Assets and Claims increased by 173.9% for the three-month period ended March 31, 2020 compared to the same period of 2019, mainly due to an increase in expected loss with loan operations and lease operations of R$5,923 million for the three- month period ended March 31, 2020.

o Coverage ratio (90 days): We calculate our coverage ratio as provisions for expected losses to 90-day non-performing loans. As of March 31, 2020, our coverage ratio was 196.7% compared to a ratio of 171.5% as of March 31, 2019. This increase was mainly due to increased provisions for expected losses from loans to individuals, driven by an increase in the balance of our loan portfolio for this segment and the changes in the macroeconomic scenario and financial perspectives for individuals and companies as of the second half of March 2020 as a result of the COVID-19 pandemic, which was captured by our expected loss provisioning model. The chart below shows a comparison in the coverage ratios for each quarter as of March 31, 2019 through March 31, 2020: • Other Operating Income (Expenses) decreased by 12.6% to an expense of R$13,176 million for the three-month period ended March 31, 2020 from an expense of R$15,077 million for the same period of 2019, mainly due to: (i) reduced fixed costs, as a result of closing of brick and mortar branches; (ii) reduced personnel expenses, as a result of a reduction in the number of branches and our 2019 voluntary severance program; and (iii) reduced profit sharing, data processing and telecommunications expenses. Please see “Note 23—General and administrative expenses” to our unaudited interim consolidated financial statements for further details. 11 o Coverage ratio (90 days): We calculate our coverage ratio as provisions for expected losses to 90-day non-performing loans. As of March 31, 2020, our coverage ratio was 196.7% compared to a ratio of 171.5% as of March 31, 2019. This increase was mainly due to increased provisions for expected losses from loans to individuals, driven by an increase in the balance of our loan portfolio for this segment and the changes in the macroeconomic scenario and financial perspectives for individuals and companies as of the second half of March 2020 as a result of the COVID-19 pandemic, which was captured by our expected loss provisioning model. The chart below shows a comparison in the coverage ratios for each quarter as of March 31, 2019 through March 31, 2020: • Other Operating Income (Expenses) decreased by 12.6% to an expense of R$13,176 million for the three-month period ended March 31, 2020 from an expense of R$15,077 million for the same period of 2019, mainly due to: (i) reduced fixed costs, as a result of closing of brick and mortar branches; (ii) reduced personnel expenses, as a result of a reduction in the number of branches and our 2019 voluntary severance program; and (iii) reduced profit sharing, data processing and telecommunications expenses.

• Current and deferred income and social contribution taxes amounted to a gain of R$12,965 million for the three-month period ended March 31, 2020, from an expense of R$2,635 million for the same period of 2019. This was mainly due to the fiscal effect on the hedging instruments for our investments abroad, as mentioned in “—Net interest income,” which amounted to a gain of R$13,023 million for the three-month period ended March 31, 2020 compared to a gain of R$111 million for the same period of 2019. Disregarding this fiscal effect, current and deferred income and social contribution taxes decreased 97.9% for the three-month period ended March 31, 2020 compared to the same period of 2019. This decrease is mainly a result of: (i) increases in provisions for expected loss in the period (which generate tax credits) and (ii) a decrease in net income before tax and social contribution. In the three-month period ended March 31, 2019, the nominal rate for income and social contribution taxes was 40% and as of March 1, 2020 the nominal rate was increased to 45%.

Net income from Retail Banking decreased by 42.8%, to R$1,760 million for the three-month period ended March 31, 2020 from R$3,074 million for the same period of 2019. These results are explained as follows: • Operating revenues: increased by 6.1% for the three-month period ended March 31, 2020 compared to the same period of 2019, mainly due to a 12.6% increase in our loan portfolio for this segment, mainly as a result of increased credit origination, particularly in small and middle market companies portfolios. • Cost of credit and claims increased by 83.3% for the three-month period ended March 31, 2020 compared to the same period of 2019, mainly due to the change in the macroeconomic scenario and the financial perspectives for individuals and companies as of the second half of March 2020, as a result of the COVID-19 pandemic.

Activities with the Market + Corporation segment for the three-month periods ended March 31, 2020 and 2019: Net income from Activities with the Market + Corporation decreased 8.8% to R$1,425 million for the three-month period ended March 31, 2020 from R$1,564 million for the same period of 2019, mainly due to the impact on the valuation of financial instruments as of the second half of March 2020 as a result of the COVID-19 pandemic, which resulted in lower gains in the over-hedge strategy of our investments abroad and our trading desk. • Income tax and social contribution for this segment, as well as for the Retail Banking and Wholesale Banking segments, is calculated by adopting the full income tax rate, net of the tax effect of any payment of interest on capital. The difference between the income tax amount determined for each segment and the effective income tax amount, as stated in our unaudited interim consolidated financial statements, is recorded under the Activities with the Market + Corporation segment. As discussed above, our current and deferred income and social contribution taxes decreased mainly a result of: (i) increases in provisions for expected loss in the period (which generate tax credits) and (ii) a decrease in net income before tax and social contribution.

Liquidity Ratios The Basel III Framework introduced global liquidity standards, providing for minimum liquidity requirements and aims to ensure that banks can rely on their own sources of liquidity, leaving central banks as a lender of last resort. Basel III provides for two liquidity ratios to ensure that financial institutions have sufficient liquidity to meet their short-term and long-term obligations: (i) the liquidity coverage ratio, or LCR, and (ii) the net stable funding ratio, or NSFR. We believe that the LCR and NSFR provide more relevant information than an analysis of summarized cash flows. Our independent auditors review our LCR and NSFR and we are required to report these figured to the Central Bank on a quarterly basis. We present below a discussion of our LCR and NSFR for the three-month period ended March 31, 2020. Liquidity Coverage Ratio The LCR measures the short-term resistance of a bank’s liquidity risk profile. It is the ratio of the stock of high quality liquid assets to expected net cash outflows over the next 30 days, assuming a scenario of idiosyncratic or systemic liquidity stress. We calculate our LCR according to the methodology established in Central Bank Circular 3,749/2015. We measure our total high liquidity assets for the end of each period to cash outflows and inflows as the daily average value for each period. Pursuant to Central Bank regulations, effective as of January 1, 2019, the minimum LCR is 100%. 21 As of March 31, 2020, our Tier I capital ratio was 12.0% and our Common Equity Tier I ratio reached 10.3%.

Capital Management Capital Adequacy Through ICAAP (Internal Capital Adequacy Assessment Process), we assess the adequacy of our capital to face incurred risks, consisting of regulatory capital for credit, market and operational risks and capital required to cover other risks. In order to ensure the soundness and the availability of our capital to support business growth, we maintain capital levels above the minimum requirements, according to the Common Equity Tier I, Additional Tier I Capital, and Tier II minimum ratios. 25 Capital Management Capital Adequacy Through ICAAP (Internal Capital Adequacy Assessment Process), we assess the adequacy of our capital to face incurred risks, consisting of regulatory capital for credit, market and operational risks and capital required to cover other risks.

As of March 31, 2020, our Total Capital reached R$ 139,218 million, a decrease of R$ 1,378 million compared to December 31, 2019. Capital ratios Our Total Capital, Tier I Capital and Common Equity Tier I Capital ratios are calculated on a consolidated basis, applied to institutions included in our Prudential Conglomerate, which comprises not only financial institutions but also consortia, payment entities, factoring companies or companies that directly or indirectly assume credit risk, and investment funds in which we substantially retain risks and rewards. Our Total Capital ratio reached 13.3% as of March 31, 2020, a decrease of 250 basis points compared to December 31, 2019, mainly due to (i) higher exposure of Credit Risk-Weighted Assets (RWACPAD), as a result of exchange rate fluctuations and the growth of our credit portfolio, and (ii) the payment of additional dividends and interest on capital mainly relating to our 2019 earnings. This decrease was partially offset by our net income from this period and the issuance of Tier 1 Subordinated Notes and Tier 2 Subordinated Notes.

E. Off-Balance Sheet Arrangements We do not have any off-balance sheet arrangements, other than the guarantees, financial guarantees, commitments to be released, letters of credit to be released and contractual commitments we granted that are described in “Note 13 - Fixed assets,” “Note 14 - Goodwill and Intangible assets,” “Note 32 – Risk and Capital Management, 1.1 – Collateral and policies for mitigating credit risk” and “Note 32 – 1.4 – Maximum Exposure of Financial Assets to Credit Risk” to our unaudited interim consolidated financial statements. RECENT DEVELOPMENTS Supervision and Regulation Recent Developments This section presents a summary of certain measures adopted by the CMN and the Central Bank to address the consequences of the COVID-19 pandemic on the Brazilian financial system, as well as the new open banking regulations. (a) Central Bank authorized to buy and sell government bonds and private financial assets and securities in the secondary market Constitutional Amendment No. 106, enacted on May 7, 2020, sets forth emergency economic and budget measures for the Brazilian government during the COVID-19 pandemic. Among them, the amendment authorizes the Central Bank, for the duration of the pandemic, to buy and sell (i) government bonds in local and foreign secondary markets; and (ii) other assets, in domestic secondary financial, capital and payments markets, provided that, at the time of purchase, they have a credit risk rating in the local market greater than or equal to BB-, conferred by at least one of the three largest international rating agencies, as well as a reference price published by a financial market entity accredited by the Central Bank. (b) Open Banking Regulation On May 4, 2020, the Central Bank and the CMN enacted Joint Resolution No. 1, which regulates open banking. Open banking consists of the sharing of data and payment initiation services and forwarding credit transaction proposals, by financial institutions and other authorized entities, upon customers’ authorization and integration of information systems. Among other topics, the resolution sets forth the mandatory and voluntary participating institutions, the data and services covered, the requirements for sharing, the responsibilities for sharing, the implementation schedule and the convention to be concluded between the participating institutions. According to the resolution, financial institutions and prudential conglomerates belonging to the S1 and S2 segments, as is our case, are required to participate in open banking. 27 E. Off-Balance Sheet Arrangements We do not have any off-balance sheet arrangements, other than the guarantees, financial guarantees, commitments to be released, letters of credit to be released and contractual commitments we granted that are described in “Note 13 - Fixed assets,” “Note 14 - Goodwill and Intangible assets,” “Note 32 – Risk and Capital Management, 1.1 – Collateral and policies for mitigating credit risk” and “Note 32 – 1.4 – Maximum Exposure of Financial Assets to Credit Risk” to our unaudited interim consolidated financial statements.

Open banking has a four-stage implementation plan, as follows: • Stage 1 (by November 30, 2020): public access to participating institutions’ data on their access channels and product/service channels related to checking, savings, prepaid payment accounts and to lending transactions. • Stage 2 (by May 31, 2021): sharing of customer reference data and customer transactional data among the participating institutions. • Stage 3 (by August 30, 2021): sharing of payment transaction initiation services, as well as forwarding credit transaction proposals. • Stage 4 (by October 25, 2021): expansion of in-scope data to encompass foreign exchange, investment, insurance, and open-end private pension transactions. (c) CMN and Central Bank regulate the electronic issuance of trade bills (duplicatas mercantis) On May 4, 2020, the CMN and the Central Bank issued Resolution No. 4,815 and Circular No. 4,016, respectively, which regulate the electronic issuance of trade bills, which is a common debt instrument used in business sales. Considering that Law No. 13,775/2018 allowed the issuance of trade bills through entry in an electronic bookkeeping system, these rules govern the bookkeeping, registration, settlement and negotiation of the instruments. Under the regulation, it is the obligation of the bookkeeper to certify the validity and uniqueness of the trade bill, in addition to controlling the payment flow to its legitimate holder. In addition, through registration, the company issuing the bill will be able to access more easily share information about these receivables with different financial institutions, permitting an increase in competition for the financing of the bills and ensuring further security for the financial institutions. Both rules will enter into effect on June 1, 2020. 28 Open banking has a four-stage implementation plan, as follows: • Stage 1 (by November 30, 2020): public access to participating institutions’ data on their access channels and product/service channels related to checking, savings, prepaid payment accounts and to lending transactions. • Stage 2 (by May 31, 2021): sharing of customer reference data and customer transactional data among the participating institutions. • Stage 3 (by August 30, 2021): sharing of payment transaction initiation services, as well as forwarding credit transaction proposals. • Stage 4 (by October 25, 2021): expansion of in-scope data to encompass foreign exchange, investment, insurance, and open-end private pension transactions.

Management believes that the information included in these Consolidated Financial Statements is relevant and a faithful representation of the information used in the management of the ITAÚ UNIBANCO HOLDING. 2.2. New accounting standards changes and interpretations of existing standards a) Accounting standards applicable for period ended March 31, 2020 • Amendment in Conceptual Framework – The main changes refer to: definitions of assets and liabilities, recognition criteria, derecognition, measurement, presentation and disclosure for equity and st results elements. These changes are effective for the years started on January 1 , 2020 and there are no impacts on the Consolidated Financial Statements of ITAÚ UNIBANCO HOLDING. • Amendments to IFRS 9 – Financial Instruments, IAS 39 – Financial Instruments: Recognition and Measurement and IFRS 7 – Financial Instruments: Disclosures – Due to the changes in the interest rates used as market references – IBOR (Interbank Offered Rate), that will be terminated in future periods, there may be uncertainties in the evaluation of hedge accounting structures. Regulatory changes aim at minimizing possible impacts on these structures in the current scenario of prereplacement of rates. The regulatory exemption setting forth that these rates will not be replaced during the period of uncertainty in the analysis of hedge accounting relationships will be applied. st These changes are effective for the years beginning January 1 , 2020 and they will be applied until the effective replacement of IBORs occurs or until the hedge accounting relationships are discontinued. No significant impacts have been identified in the hedge accounting structures for the Consolidated Financial Statements of ITAÚ UNIBANCO HOLDING, in the prereplacement period of IBORs. ITAÚ UNIBANCO HOLDING is exposed mainly to Libor and Euribor rates in hedge accounting structures. Since 2018, ITAÚ UNIBANCO HOLDING brings together working groups to follow the progress of discussions in the international market about the replacement of IBORs. For standardized agreements, ITAÚ UNIBANCO HOLDING will assume the updates of rates made by the respective clearings and the International Swaps and Derivatives Association - ISDA). For the other agreements, whenever possible, they will be negotiated and adjusted gradually until the end of 2021, date on which the market expects the end of disclosures of IBORs. b) Accounting standards recently issued and applicable in future periods • IFRS 17 – Insurance Contracts: The pronouncement replaces IFRS 4 – Insurance Contracts and presents three approaches for valuation: • General Model: applicable to all contracts without direct participation features; Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.9 Note 2 – Significant accounting policies 2.1.

• Premium Allocation Approach (PAA): applicable to contracts with term is up to 12 months or when it produces results similar to those that would be obtained if the general model was used. It is more simplified than the general model; • Variable Fee Approach: applicable to insurance contracts with direct participation features, the insurance contracts which are substantially investment related service contracts under which an entity promises an investment return based on underlying items. Insurance contracts must be recognized based on an analysis of four components: • Expected Future Cash Flows: estimate of all components of cash flow of the contract, considering inflows and outflows; • Risk Adjustment: estimate of offset required for differences that may occur between cash flows; • Contractual Margin: difference between any amounts received before the beginning of the contract coverage and present value of cash flows estimated at the beginning of the contract; • Discount: projected cash flows must be discounted to present value, to reflect the time value of money, at rates that reflect the characteristics of the respective flows. st This standard is effective for annual periods beginning January 1 , 2021. Possible impacts are being assessed and the assessment will be completed by the date this standard comes into force. 2.3. Critical accounting estimates and judgments The preparation of Consolidated Financial Statements in accordance with the IFRS 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 Consolidated Financial Statements, due to uncertainties and the high level of subjectivity involved in the recognition and measurement of certain items. Estimates and judgments considered more relevant by ITAÚ UNIBANCO HOLDING are related to the following topics: Topic Notes Consolidation Note 2.3 (a) and Note 3 Fair Value of Financial Instruments Note 2.3 (b) and Note 28 Effective Interest Rate Note 2.3 (c), Notes 5, 8, 9 and 10 Change to Financial Assets Note 2.3 (d), Notes 5, 8, 9 and 10 Transfer and Write-off of Financial Assets Note 2.3 (e), Notes 5, 8, 9 and 10 Expected Credit Loss Note 2.3 (f), Notes 8, 9 and 10 Goodwill Impairment Note 2.3 (g) and Note 14 Deferred Income Tax and Social Contribution Note 2.3 (h) and Note 24 Defined Benefit Pension Plan Note 2.3 (i) and Note 26 Provisions, Contingencies and Legal Liabilities Note 2.3 (j) and Note 29 Technical Provisions for Insurance and Private Pension Note 2.3 (k) and Note 27 a) Consolidation Subsidiaries are all those in which ITAÚ UNIBANCO HOLDING’s involvement exposes it or entitles it to variable returns and can affect these returns through its influence on the entity. 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. b) Fair value of financial instruments are not traded in active markets, including derivatives 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 28. Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.10 • Premium Allocation Approach (PAA): applicable to contracts with term is up to 12 months or when it produces results similar to those that would be obtained if the general model was used. It is more simplified than the general model; • Variable Fee Approach: applicable to insurance contracts with direct participation features, the insurance contracts which are substantially investment related service contracts under which an entity promises an investment return based on underlying items. Insurance contracts must be recognized based on an analysis of four components: • Expected Future Cash Flows: estimate of all components of cash flow of the contract, considering inflows and outflows; • Risk Adjustment: estimate of offset required for differences that may occur between cash flows; • Contractual Margin: difference between any amounts received before the beginning of the contract coverage and present value of cash flows estimated at the beginning of the contract; • Discount: projected cash flows must be discounted to present value, to reflect the time value of money, at rates that reflect the characteristics of the respective flows. st This standard is effective for annual periods beginning January 1 , 2021. Possible impacts are being assessed and the assessment will be completed by the date this standard comes into force. 2.3. Critical accounting estimates and judgments The preparation of Consolidated Financial Statements in accordance with the IFRS 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 Consolidated Financial Statements, due to uncertainties and the high level of subjectivity involved in the recognition and measurement of certain items. Estimates and judgments considered more relevant by ITAÚ UNIBANCO HOLDING are related to the following topics: Topic Notes Consolidation Note 2.3 (a) and Note 3 Fair Value of Financial Instruments Note 2.3 (b) and Note 28 Effective Interest Rate Note 2.3 (c), Notes 5, 8, 9 and 10 Change to Financial Assets Note 2.3 (d), Notes 5, 8, 9 and 10 Transfer and Write-off of Financial Assets Note 2.3 (e), Notes 5, 8, 9 and 10 Expected Credit Loss Note 2.3 (f), Notes 8, 9 and 10 Goodwill Impairment Note 2.3 (g) and Note 14 Deferred Income Tax and Social Contribution Note 2.3 (h) and Note 24 Defined Benefit Pension Plan Note 2.3 (i) and Note 26 Provisions, Contingencies and Legal Liabilities Note 2.3 (j) and Note 29 Technical Provisions for Insurance and Private Pension Note 2.3 (k) and Note 27 a) Consolidation Subsidiaries are all those in which ITAÚ UNIBANCO HOLDING’s involvement exposes it or entitles it to variable returns and can affect these returns through its influence on the entity. 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. b) Fair value of financial instruments are not traded in active markets, including derivatives 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 28.

c) Effective Interest Rate To calculate the effective interest rate, ITAÚ UNIBANCO HOLDING estimates cash flows taking into account all the contractual terms of the financial instrument, but without including future credit losses. The calculation includes all commissions paid or received between parties to the contract, transaction costs, and all other premiums or discounts. Interest revenue is calculated by applying the effective interest rate to the gross carrying amount of a financial asset. In the case of purchased or originated credit impaired financial assets, the adjusted effective interest rate is applied (taking into account the expected credit loss) to the amortized cost of the financial asset. d) Modification of Financial Assets The factors used to determine whether has been substantial modification of a contract are: evaluation if there is a renegotiation that is not part of the original contractual terms, change to contractual cash flows and significant extensions of the term of the transaction due to the debtor's financial constraints, significant changes to the interest rate and changes to the currency in which the transaction is denominated. e) Transfer and write-off of Financial Assets When there are no reasonable expectations of recovery of a financial asset, considering historical curves, its total or partial write-off is carried out concurrently with the use of the related allowance for expected credit loss, with no effect on the Consolidated Statement of Income of ITAÚ UNIBANCO HOLDING. Subsequent recoveries of amounts previously written off are accounted for as income in the Consolidated Statement of Income. Thus, financial assets are written off, either totally or partially, when there is no reasonable expectation of recovering a financial asset or when ITAÚ UNIBANCO HOLDING substantially transfers all risks and benefits of ownership and said transfer is qualified to be written off. f) Expected Credit Loss The measurement of expected credit loss requires the application of significant assumptions, such as: • Term to maturity: ITAÚ UNIBANCO HOLDING considers the maximum contractual period on which it will be exposed a financial instrument’s credit risk. However, the estimated useful life of assets that do not have fixed maturity date is based on the period of exposure to credit risk. Additionally, all contractual terms are taken into account when determining the expected life, including prepayment and rollover options. • Prospective information: IFRS 9 requires a balanced and impartial estimate of credit loss that includes forecasts of future economic conditions. ITAÚ UNIBANCO HOLDING uses prospective macroeconomic information and public information with projections prepared internally to determine the impact of these estimates on the calculation of expected credit loss. • Probability-weighted loss scenarios: ITAÚ UNIBANCO HOLDING uses weighted scenarios to determine credit loss expected over a suitable observation horizon adequate to classification in phases, considering the projection based on economic variables. Macroeconomic scenarios: This information involves inherent risks, market uncertainties and other factors that may give rise to results different from expected. • Determining criteria for significant increase or decrease in credit risk: in each period of the consolidated financial statements, ITAÚ UNIBANCO HOLDING assesses whether the credit risk on a financial asset has increased significantly since the initial recognition using relative and absolute triggers (indicators), which consider delay and the probability of default (PD) by product and by country. Brazilian and foreign government securities are considered to have low credit risk, in accordance with a study conducted by ITAÚ UNIBANCO HOLDING and therefore they remain in stage 1.

Significant increase in credit risk: ITAÚ UNIBANCO HOLDING assesses several factors to determine a significant increase in credit risk, such as: the counterparty, type and characteristics of the product and region in which it was contracted, considering the following objective criteria as minimum factors: • Stage 1 to stage 2: default exceeding 30 days, except for payroll loans for government agency, which are recognized is made after 45 days in arrears; • Stage 2 to stage 3: default exceeding 90 days, except for the mortgage loan portfolio, for which arrears of 180 days is a parameter for stage migration. ITAÚ UNIBANCO HOLDING assesses whether the credit risk has significantly increased on an individual or collective basis. For collective assessment purposes, financial assets are grouped based on characteristics of shared credit risk, considering the type of instrument, credit risk classifications, initial recognition date, remaining term, industry, geographical location of the counterparty, among other significant factors. Details on the expected credit loss are in Note 32. g) 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. These flows are subject to market conditions and uncertain factors, as follows: • Cash flows projected for periods of available forecasts and long-term assumptions for these flows; • Discount rates, since they generally reflect 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. Goodwill is allocated to cash flow generating units for purposes of testing for impairment. h) Deferred income tax and social contribution As explained in Note 2.4j, deferred tax assets are recognized only in relation to deductible temporary differences, tax losses and social contribution loss carryforwards for offset only to the extent that it is probable that ITAÚ UNIBANCO HOLDING will generate future taxable profit for its use. The expected realization of deferred tax assets is based on the projection of future taxable profits and technical studies, as disclosed in Note 24. i) Defined benefit pension plan 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 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 26. Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.12 Significant increase in credit risk: ITAÚ UNIBANCO HOLDING assesses several factors to determine a significant increase in credit risk, such as: the counterparty, type and characteristics of the product and region in which it was contracted, considering the following objective criteria as minimum factors: • Stage 1 to stage 2: default exceeding 30 days, except for payroll loans for government agency, which are recognized is made after 45 days in arrears; • Stage 2 to stage 3: default exceeding 90 days, except for the mortgage loan portfolio, for which arrears of 180 days is a parameter for stage migration.

j) Provisions, contingencies and legal liabilities ITAÚ UNIBANCO HOLDING 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 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 29. k) Technical provisions for insurance and private pension Technical provisions are liabilities arising from obligations of ITAÚ UNIBANCO HOLDING to its policyholders and participants. These obligations may be short term liabilities (property and casualty insurance) or medium and long term liabilities (life insurance and pension plans). The determination of the actuarial liability is subject to several uncertainties inherent in the coverage of insurance and pension contracts, such as assumptions of persistence, mortality, disability, life expectancy, morbidity, expenses, frequency and severity of claims, conversion of benefits into annuities, redemptions and return on assets. The estimates for these assumptions are based on the historical experience of ITAÚ UNIBANCO HOLDING, benchmarks and the experience of the actuary, in order to comply with best market practices and constantly review of the actuarial liability. The adjustments resulting from these continuous improvements, when necessary, are recognized in the statement of income for the corresponding period. Additional information is described in Note 27. 2.4. Summary of main accounting practices a) Consolidation l. Subsidiaries In accordance with IFRS 10 - Consolidated Financial Statements, subsidiaries are all entities in which ITAÚ UNIBANCO HOLDING holds control. Consolidated financial statements are prepared using consistent accounting policies. Intra-Group transactions and balances are eliminated on consolidation. In the 3rd quarter of 2018, ITAÚ UNIBANCO HOLDING started adjusting the financial statements of its subsidiaries in Argentina to reflect the effects of hyperinflation, pursuant to IAS 29 – Financial Reporting in Hyperinflationary Economies.

II. Business combinations In general, a business consists of an integrated set of activities and assets that may be conducted and managed so as to provide a return, in the form of dividends, lower costs or other economic benefits, to investors or other stockholders, members or participants. If there is goodwill in a set of activities and assets transferred, it is presumed to be a business. The acquisition method is used to account for business combinations, except for those classified as under common control. Acquisition cost is measured at the fair value of the assets transferred, equity instruments issued and liabilities incurred or assumed at the acquisition date. Acquired assets and assumed liabilities and contingent liabilities identifiable in a business combination are initially measured at fair value at the date of acquisition, regardless of the existence of non-controlling interests. When the amount paid, plus non-controlling interests, is higher than the fair value of identifiable net assets acquired, the difference will be accounted for as goodwill. On the other hand, if the difference is negative, it will be treated as bargain purchase gain and the amount will be recognized directly in income. III. Goodwill Goodwill is not amortized, but its recoverable value is assessed semi-annually or when there is an indication of impairment loss using an approach that involves the identification of Cash Generating Units (CGUs) and the estimate of its fair value less selling costs and/or its value in use. To determine this estimate, ITAÚ UNIBANCO HOLDING adopts the discounted cash flow methodology for a period of 5 years, macroeconomic assumptions, growth rate and discount rate. The units or Cash Flow Generating Units are identified at the lowest level in which goodwill is monitored for internal Management purposes. Goodwill is allocated to cash flow generating units for purposes of testing for impairment. The breakdown of intangible assets is described in Note 14. IV. Capital Transactions with non-controlling stockholders IFRS 10 – Consolidated Financial Statements establishes that, 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. b) Foreign currency translation I. Functional and presentation currency The Consolidated Financial Statements of ITAÚ UNIBANCO HOLDING are presented in Brazilian Reais, its functional and presentation currency. For each subsidiary, joint venture or investment in associates, ITAÚ UNIBANCO HOLDING 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 investment in foreign operation, when they are recognized in stockholders’ equity. c) Cash and cash equivalents Defined as cash and current accounts with banks, shown in the Consolidated Balance Sheet under the heading Cash, Interbank Deposits and Securities purchased under agreements to resell (Collateral Held) with original maturities not exceeding 90 days.

Business combinations In general, a business consists of an integrated set of activities and assets that may be conducted and managed so as to provide a return, in the form of dividends, lower costs or other economic benefits, to investors or other stockholders, members or participants. If there is goodwill in a set of activities and assets transferred, it is presumed to be a business. The acquisition method is used to account for business combinations, except for those classified as under common control. Acquisition cost is measured at the fair value of the assets transferred, equity instruments issued and liabilities incurred or assumed at the acquisition date. Acquired assets and assumed liabilities and contingent liabilities identifiable in a business combination are initially measured at fair value at the date of acquisition, regardless of the existence of non-controlling interests. When the amount paid, plus non-controlling interests, is higher than the fair value of identifiable net assets acquired, the difference will be accounted for as goodwill. On the other hand, if the difference is negative, it will be treated as bargain purchase gain and the amount will be recognized directly in income. III. Goodwill Goodwill is not amortized, but its recoverable value is assessed semi-annually or when there is an indication of impairment loss using an approach that involves the identification of Cash Generating Units (CGUs) and the estimate of its fair value less selling costs and/or its value in use. To determine this estimate, ITAÚ UNIBANCO HOLDING adopts the discounted cash flow methodology for a period of 5 years, macroeconomic assumptions, growth rate and discount rate. The units or Cash Flow Generating Units are identified at the lowest level in which goodwill is monitored for internal Management purposes. Goodwill is allocated to cash flow generating units for purposes of testing for impairment. The breakdown of intangible assets is described in Note 14. IV. Capital Transactions with non-controlling stockholders IFRS 10 – Consolidated Financial Statements establishes that, 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. b) Foreign currency translation I. Functional and presentation currency The Consolidated Financial Statements of ITAÚ UNIBANCO HOLDING are presented in Brazilian Reais, its functional and presentation currency. For each subsidiary, joint venture or investment in associates, ITAÚ UNIBANCO HOLDING 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 investment in foreign operation, when they are recognized in stockholders’ equity. c) Cash and cash equivalents Defined as cash and current accounts with banks, shown in the Consolidated Balance Sheet under the heading Cash, Interbank Deposits and Securities purchased under agreements to resell (Collateral Held) with original maturities not exceeding 90 days.

d) Financial Assets and Liabilities Financial assets and liabilities are initially recognized at fair value and subsequently measured at amortized cost or fair value. I - Classification and Measurement of Financial Assets Financial assets are classified in the following categories: • Amortized Cost: used when financial assets are managed to obtain contractual cash flows, consisting solely of payments of principal and interest; • Fair Value Through Other Comprehensive Income: used when financial assets are held both for obtaining contractual cash flows, consisting solely by payments of principal and interest, and for sale; • Fair Value Through Profit or Loss: used for financial assets that do not meet the aforementioned criteria. The classification and subsequent measurement of financial assets depend on: • The business model under which they are managed; • The characteristics of their cash flows (Solely Payment of Principal and Interest Test – SPPI Test). Business model: represents how financial assets are managed to generate cash flows and does not depend on the Management’s intention regarding an individual instrument. Financial assets may be managed with the purpose of: i) obtaining contractual cash flows; ii) obtaining contractual cash flows and sale; or iii) others. To assess business models, ITAÚ UNIBANCO HOLDING considers risks that affect the performance of the business model; how the managers of the business are compensated; and how the performance of the business model is assessed and reported to Management. When a financial asset is subject to business models i) or ii) the application of the SPPI Test is required. SPPI Test: assessment of cash flows generated by a financial instrument for the purpose of checking whether they represent solely payments of principal and interest. To fit into this concept, cash flows should include only consideration for the time value of money and credit risk. If contractual terms introduce risk exposure or cash flow volatilities, such as exposure to changes in prices of equity instruments or prices of commodities, the financial asset is classified at fair value through profit or loss. Hybrid contracts must be assessed as a whole, including all embedded characteristics. The accounting of a hybrid contract that contains an embedded derivative is performed on a joint basis, i.e. the whole instrument is measured at fair value through profit or loss. Amortized Cost Amortized cost is the amount for which a financial asset or liability is measured at its initial recognition, plus adjustments made under the effective interest method, less amortization of principal and interest, and any provision for expected credit loss. Fair Value Fair value is the price that would be received for the sale of an asset or that would be paid for the transfer of a liability in an orderly transaction between market players on the measurement date. ITAÚ UNIBANCO HOLDING classifies the fair value hierarchy according to the relevance of data observed in the measurement process. Details of the fair value of financial instruments, including Derivatives, and of the hierarchy of fair value are given in Note 28. Average cost is used to determine the gains and losses realized on disposal of financial assets at fair value, which are recorded in the Consolidated Statement of Income as Adjustments to Fair Value of Financial Assets and Liabilities. Dividends on assets at fair value through other comprehensive Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.16 d) Financial Assets and Liabilities Financial assets and liabilities are initially recognized at fair value and subsequently measured at amortized cost or fair value.

Fair Value Fair value is the price that would be received for the sale of an asset or that would be paid for the transfer of a liability in an orderly transaction between market players on the measurement date. ITAÚ UNIBANCO HOLDING classifies the fair value hierarchy according to the relevance of data observed in the measurement process. Details of the fair value of financial instruments, including Derivatives, and of the hierarchy of fair value are given in Note 28. Average cost is used to determine the gains and losses realized on disposal of financial assets at fair value, which are recorded in the Consolidated Statement of Income as Adjustments to Fair Value of Financial Assets and Liabilities. Dividends on assets at fair value through other comprehensive Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.16

income are recognized in the Consolidated Statement of Income as Dividend income when it is probable that ITAÚ UNIBANCO HOLDING’s right to receive such dividends is assured. Regular purchases and sales of financial assets are recognized and derecognized, respectively, on the trading date. Financial assets and liabilities are offset against each other and the net amount is reported in the Balance Sheet only solely when there is a legally enforceable right to offset them and the intention to settle them on a net basis, or to simultaneously realize the asset and settle the liability. Equity Instruments An equity instrument is any contract that evidences a residual interest in an entity’s assets, after the deduction of all its liabilities, such as Shares and Units. ITAÚ UNIBANCO HOLDING subsequently measures all its equity instruments at fair value through profit or loss, except when Management opts, on initial recognition, to irrevocably designate an equity instrument at fair value through other comprehensive income when it is held for a purpose other than only generating returns. When this option is selected, gains and losses on the fair value of the instrument are recognized in the Consolidated Statement of Comprehensive Income and are not subsequently reclassified to the Consolidated Statement of Income, even on sale. Dividends continue to be recognized in the Consolidated Statement of Income when ITAÚ UNIBANCO HOLDING’s right to receive them is assured. Gains and losses on equity instruments measured at fair value through profit or loss are accounted in the Consolidated Statement of Income. Expected Credit Loss ITAÚ UNIBANCO HOLDING makes a forward-looking assessment of the expected credit loss on financial assets measured at amortized cost or through other comprehensive income, loan commitments and financial guarantee contracts: • Financial assets: loss is measured at present value of the difference between contractual cash flows and the cash flows that ITAÚ UNIBANCO HOLDING expects to receive; • Loan commitments: expected loss is measured at present value of the difference between contractual cash flows that would be due if the commitment was drawn down and the cash flows that ITAÚ UNIBANCO HOLDING expects to receive; • Financial guarantees: the loss is measured at the difference between the payments expected for refunding the counterparty and the amounts that ITAÚ UNIBANCO HOLDING expects to recover. ITAÚ UNIBANCO HOLDING applies a three-stage approach to measuring the expected credit loss, in which financial assets migrate from one stage to the other in accordance with changes in credit risk. • Stage 1 – 12-month expected credit loss: represents default events possible within 12 months. Applicable to financial assets which are not credit impaired when purchased or originated; • Stage 2 – Lifetime expected credit loss of financial instrument: considers all possible default events. Applicable to financial assets originated which are not credit impaired when originated or purchased but for which credit risk has increased significantly; and • Stage 3 – Credit loss expected for credit-impaired assets: considers all possible default events. Applicable to financial assets which are credit impaired when purchased or originated. The measurement of assets classified in this stage is different from Stage 2 due to the recognition of interest income by applying the effective interest rate to amortized cost (net of provision) rather than to the gross carrying amount. Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.17 income are recognized in the Consolidated Statement of Income as Dividend income when it is probable that ITAÚ UNIBANCO HOLDING’s right to receive such dividends is assured. Regular purchases and sales of financial assets are recognized and derecognized, respectively, on the trading date. Financial assets and liabilities are offset against each other and the net amount is reported in the Balance Sheet only solely when there is a legally enforceable right to offset them and the intention to settle them on a net basis, or to simultaneously realize the asset and settle the liability. Equity Instruments An equity instrument is any contract that evidences a residual interest in an entity’s assets, after the deduction of all its liabilities, such as Shares and Units. ITAÚ UNIBANCO HOLDING subsequently measures all its equity instruments at fair value through profit or loss, except when Management opts, on initial recognition, to irrevocably designate an equity instrument at fair value through other comprehensive income when it is held for a purpose other than only generating returns. When this option is selected, gains and losses on the fair value of the instrument are recognized in the Consolidated Statement of Comprehensive Income and are not subsequently reclassified to the Consolidated Statement of Income, even on sale. Dividends continue to be recognized in the Consolidated Statement of Income when ITAÚ UNIBANCO HOLDING’s right to receive them is assured. Gains and losses on equity instruments measured at fair value through profit or loss are accounted in the Consolidated Statement of Income. Expected Credit Loss ITAÚ UNIBANCO HOLDING makes a forward-looking assessment of the expected credit loss on financial assets measured at amortized cost or through other comprehensive income, loan commitments and financial guarantee contracts: • Financial assets: loss is measured at present value of the difference between contractual cash flows and the cash flows that ITAÚ UNIBANCO HOLDING expects to receive; • Loan commitments: expected loss is measured at present value of the difference between contractual cash flows that would be due if the commitment was drawn down and the cash flows that ITAÚ UNIBANCO HOLDING expects to receive; • Financial guarantees: the loss is measured at the difference between the payments expected for refunding the counterparty and the amounts that ITAÚ UNIBANCO HOLDING expects to recover. ITAÚ UNIBANCO HOLDING applies a three-stage approach to measuring the expected credit loss, in which financial assets migrate from one stage to the other in accordance with changes in credit risk. • Stage 1 – 12-month expected credit loss: represents default events possible within 12 months. Applicable to financial assets which are not credit impaired when purchased or originated; • Stage 2 – Lifetime expected credit loss of financial instrument: considers all possible default events. Applicable to financial assets originated which are not credit impaired when originated or purchased but for which credit risk has increased significantly; and • Stage 3 – Credit loss expected for credit-impaired assets: considers all possible default events. Applicable to financial assets which are credit impaired when purchased or originated. The measurement of assets classified in this stage is different from Stage 2 due to the recognition of interest income by applying the effective interest rate to amortized cost (net of provision) rather than to the gross carrying amount. Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.17

An asset will migrate between stages as its credit risk increases or decreases. Therefore, a financial asset that migrated to stages 2 and 3 may return to stage 1, unless it was purchased or originated credit impaired financial asset. Macroeconomic Scenarios Forward-looking information is based on macroeconomic scenarios that are reassessed annually or when market conditions so require. Additional information is described in Note 32. Modification of Contractual Cash Flows When contractual cash flows of a financial asset are renegotiated or otherwise modified and this does not substantially change its terms and conditions, ITAÚ UNIBANCO HOLDING does not derecognize it. However, the gross carrying amount of this financial asset is recalculated as the present value of the renegotiated or changed contractual cash flows, discounted at the original effective interest rate and a modification gain or loss is recognized in profit or loss. Any costs or fees incurred adjust the modified carrying amount and are amortized over the remaining term of the financial asset. If, on the other hand, the renegotiation or change substantially modifies the terms and conditions of the financial asset, ITAÚ UNIBANCO HOLDING derecognises the original asset and recognizes a new one. Accordingly, the renegotiation date is taken as the initial recognition date of the new asset for expected credit loss calculation purposes, and to determine significant increases in credit risk. ITAÚ UNIBANCO HOLDING also assesses if the new financial asset may be considered as purchased or originated credit impaired financial asset, particularly when the renegotiation was motivated by the debtor’s financial constraints. Differences between the carrying amount of the original asset and fair value of the new asset are immediately recognized in the Consolidated Statement of Income. The effects of changes in cash flows of financial assets and other details about methodologies and assumptions adopted by Management to measure the allowance for expected credit loss, including the use of prospective information, are detailed in Note 32. Derecognition of Financial Assets Financial assets are derecognized when ITAÚ UNIBANCO HOLDING substantially transfers all risks and benefits of its property. In the event it is not possible to identify the transfer of all risks and benefits, the control should be assessed to determine the continuous involvement related to the transaction. If there is a retention of risks and benefits, the financial asset continues to be recorded and a liability is recognized for the consideration received. II – Classification and Measurement of Financial Liabilities Financial liabilities are initially recognized at fair value and subsequently measured at amortized cost, except for: • Financial Liabilities at Fair Value Through Profit or Loss: this classification applied to derivatives and other financial liabilities designated at fair value through profit or loss to reduce “accounting mismatches”. ITAÚ UNIBANCO HOLDING irrevocably designates financial liabilities at fair value through profit or loss in the initial recognition (fair value option), when the option eliminates or significantly reduces measurement or recognition inconsistencies. • Loan Commitments and Financial Guarantees: see details in Note 2.4d Vll. Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.18 An asset will migrate between stages as its credit risk increases or decreases.

Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.18

Derecognition and Modification of Financial Liabilities ITAÚ UNIBANCO HOLDING derecognises a financial liability from the Consolidated Balance Sheet when it is extinguished, i.e., when the obligation specified in the contract is discharged, cancelled or expires. A debt instrument change or substantial terms modification of a financial liability is accounted as a derecognition of the original financial liability and a new one is recognized. A substantial change to contractual terms occurs when the discounted present value of cash flows under the new terms, including any fees paid/received and discounted using the original effective interest rate, is at least 10% different from discounted present value of the remaining cash flow of the original financial liabilities. III – Securities purchased under agreements to resell ITAÚ UNIBANCO HOLDING purchases financial assets with a resale commitment (resale agreements) and sells securities with a repurchase commitment (repurchase agreement) of financial assets. Resale and repurchase agreements are accounted for under Securities purchased under agreements to resell and Securities sold under repurchase agreements, respectively. The difference between the sale and repurchase prices is treated as interest and recognized over the life of the agreements using the effective interest rate method. The financial assets taken as collateral in resale agreements can be used as collateral for repurchase agreements it provided for in the agreements or can be sold. IV - Derivatives All derivatives are accounted for as financial assets when the fair value is positive and as financial liabilities when the fair value is negative. The valuation of active hybrid contracts that are subject to IFRS 9 is carried out as a whole, including all embedded characteristics, whereas the accounting is carried out on a joint basis, i.e. each instrument is measured at fair value through profit or loss. When a contract has a main component outside the scope of IFRS 9, such as a lease agreement receivable or an insurance contract, or even a financial liability, embedded derivatives are treated as separate financial instruments if: (i) their characteristics and economic risks are not closely related to those of the main component; (ii) the separate instrument meets the definition of a derivative; and (iii) the underlying instrument is not booked at fair value through profit or loss. These embedded derivatives are accounted for separately at fair value, with variations recognized in the Consolidated Statement of Income as Adjustments to Fair Value of Financial Assets and Liabilities. ITAÚ UNIBANCO HOLDING will continue applying all the hedge accounting requirements of IAS 39; however, it may adopt the provisions of IFRS 9, if Management so decides. According to this standard, derivatives may be designated and qualified as hedging instruments for accounting purposes and, the method for recognizing gains or losses of fair value will depending on the nature of the hedged item. At the beginning of a hedging transaction, ITAÚ UNIBANCO HOLDING documents the relationship between the hedging instrument and the hedged items, as well as its risk management objective and strategy. The hedge is assessed on an ongoing basis to determine if it has been highly effective throughout all periods of the Financial Statements for which it was designated. IAS 39 describes three hedging strategies: fair value hedge, cash flow hedge, and hedge of net investments in a foreign operation. ITAÚ UNIBANCO HOLDING uses derivatives as hedging instruments under all three hedge strategies, as detailed in Note 7. Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.19 Derecognition and Modification of Financial Liabilities ITAÚ UNIBANCO HOLDING derecognises a financial liability from the Consolidated Balance Sheet when it is extinguished, i.e., when the obligation specified in the contract is discharged, cancelled or expires. A debt instrument change or substantial terms modification of a financial liability is accounted as a derecognition of the original financial liability and a new one is recognized. A substantial change to contractual terms occurs when the discounted present value of cash flows under the new terms, including any fees paid/received and discounted using the original effective interest rate, is at least 10% different from discounted present value of the remaining cash flow of the original financial liabilities. III – Securities purchased under agreements to resell ITAÚ UNIBANCO HOLDING purchases financial assets with a resale commitment (resale agreements) and sells securities with a repurchase commitment (repurchase agreement) of financial assets. Resale and repurchase agreements are accounted for under Securities purchased under agreements to resell and Securities sold under repurchase agreements, respectively. The difference between the sale and repurchase prices is treated as interest and recognized over the life of the agreements using the effective interest rate method. The financial assets taken as collateral in resale agreements can be used as collateral for repurchase agreements it provided for in the agreements or can be sold. IV - Derivatives All derivatives are accounted for as financial assets when the fair value is positive and as financial liabilities when the fair value is negative. The valuation of active hybrid contracts that are subject to IFRS 9 is carried out as a whole, including all embedded characteristics, whereas the accounting is carried out on a joint basis, i.e. each instrument is measured at fair value through profit or loss. When a contract has a main component outside the scope of IFRS 9, such as a lease agreement receivable or an insurance contract, or even a financial liability, embedded derivatives are treated as separate financial instruments if: (i) their characteristics and economic risks are not closely related to those of the main component; (ii) the separate instrument meets the definition of a derivative; and (iii) the underlying instrument is not booked at fair value through profit or loss. These embedded derivatives are accounted for separately at fair value, with variations recognized in the Consolidated Statement of Income as Adjustments to Fair Value of Financial Assets and Liabilities. ITAÚ UNIBANCO HOLDING will continue applying all the hedge accounting requirements of IAS 39; however, it may adopt the provisions of IFRS 9, if Management so decides. According to this standard, derivatives may be designated and qualified as hedging instruments for accounting purposes and, the method for recognizing gains or losses of fair value will depending on the nature of the hedged item. At the beginning of a hedging transaction, ITAÚ UNIBANCO HOLDING documents the relationship between the hedging instrument and the hedged items, as well as its risk management objective and strategy. The hedge is assessed on an ongoing basis to determine if it has been highly effective throughout all periods of the Financial Statements for which it was designated. IAS 39 describes three hedging strategies: fair value hedge, cash flow hedge, and hedge of net investments in a foreign operation. ITAÚ UNIBANCO HOLDING uses derivatives as hedging instruments under all three hedge strategies, as detailed in Note 7. Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.19

Fair value hedge The following practices are adopted for these operations: a) The gain or loss arising from the remeasurement of the hedging instrument at fair value is recognized in income; and b) The gain or loss arising from the hedged item, attributable to the effective portion of the hedged risk, is applied to the book value of the hedged item and is also recognized in income. When a derivative expires or is sold or a hedge no longer meets the hedge accounting criteria or in the event the designation is revoked, the hedge accounting must be prospectively discontinued. In addition, any adjustment to the book value of the hedged item must be amortized in income. Cash flow hedge For derivatives that are designated and qualify as hedging instruments in a cash flow hedge, the practices are: a) The effective portion of gains or losses on derivatives is recognized directly in Other comprehensive income – Cash flow hedge; b) The portion of gain or loss on derivatives that represents the ineffective portion or on hedge components excluded from the assessment of effectiveness is recognized in income. Amounts originally recorded in Other comprehensive income and subsequently reclassified to Income are recognized in the caption Interest, similar income and dividend of financial assets at fair value through profit or loss at the same time that the corresponding income or expense item of the financial hedge item affects income. For non-financial hedge items, the amounts originally recognized in Other Comprehensive Income are included in the initial cost of the corresponding asset or liability. When a derivative expires or is sold, when hedge accounting criteria are no longer met or when the entity revokes the hedge accounting designation, any cumulative gain or loss existing in Other comprehensive income will be reclassified to income at the time the expected transaction occurs or is no longer expected to occur. Hedge of net investments in foreign operations The hedge of a net investment in a foreign operation, including the hedge of a monetary item that is booked as part of the net investment, is accounted for in a manner similar to a cash flow hedge: a) The portion of gain or loss on the hedging instrument determined as effective is recognized in other comprehensive income; b) The ineffective portion is recognized in income. Gains or losses on the hedging instrument related to the effective portion of the hedge which are recognized in Other comprehensive income are reclassified to income for the period when the foreign operation is partially or totally sold. V - Loan operations ITAÚ UNIBANCO HOLDING classifies a loan as non-performing if the payment of the principal or interest has been overdue for 60 days or more. In this case, accrual of interest is no longer recognized. VI – Premium Bonds plans In Brazil they are regulated by the insurance regulator. These plans do not meet the definition of an insurance contract under IFRS 4, and therefore they are classified as a financial liability at amortized cost under IFRS 9. Revenue from premium bonds plans is recognized during the period of the contract and measured as the difference between the amount deposited by the customer and the amount that ITAÚ UNIBANCO HOLDING has to reimburse. Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.20 Fair value hedge The following practices are adopted for these operations: a) The gain or loss arising from the remeasurement of the hedging instrument at fair value is recognized in income; and b) The gain or loss arising from the hedged item, attributable to the effective portion of the hedged risk, is applied to the book value of the hedged item and is also recognized in income. When a derivative expires or is sold or a hedge no longer meets the hedge accounting criteria or in the event the designation is revoked, the hedge accounting must be prospectively discontinued. In addition, any adjustment to the book value of the hedged item must be amortized in income. Cash flow hedge For derivatives that are designated and qualify as hedging instruments in a cash flow hedge, the practices are: a) The effective portion of gains or losses on derivatives is recognized directly in Other comprehensive income – Cash flow hedge; b) The portion of gain or loss on derivatives that represents the ineffective portion or on hedge components excluded from the assessment of effectiveness is recognized in income. Amounts originally recorded in Other comprehensive income and subsequently reclassified to Income are recognized in the caption Interest, similar income and dividend of financial assets at fair value through profit or loss at the same time that the corresponding income or expense item of the financial hedge item affects income. For non-financial hedge items, the amounts originally recognized in Other Comprehensive Income are included in the initial cost of the corresponding asset or liability. When a derivative expires or is sold, when hedge accounting criteria are no longer met or when the entity revokes the hedge accounting designation, any cumulative gain or loss existing in Other comprehensive income will be reclassified to income at the time the expected transaction occurs or is no longer expected to occur. Hedge of net investments in foreign operations The hedge of a net investment in a foreign operation, including the hedge of a monetary item that is booked as part of the net investment, is accounted for in a manner similar to a cash flow hedge: a) The portion of gain or loss on the hedging instrument determined as effective is recognized in other comprehensive income; b) The ineffective portion is recognized in income. Gains or losses on the hedging instrument related to the effective portion of the hedge which are recognized in Other comprehensive income are reclassified to income for the period when the foreign operation is partially or totally sold. V - Loan operations ITAÚ UNIBANCO HOLDING classifies a loan as non-performing if the payment of the principal or interest has been overdue for 60 days or more. In this case, accrual of interest is no longer recognized. VI – Premium Bonds plans In Brazil they are regulated by the insurance regulator. These plans do not meet the definition of an insurance contract under IFRS 4, and therefore they are classified as a financial liability at amortized cost under IFRS 9. Revenue from premium bonds plans is recognized during the period of the contract and measured as the difference between the amount deposited by the customer and the amount that ITAÚ UNIBANCO HOLDING has to reimburse.

VII – Loan Commitments and Financial Guarantees ITAÚ UNIBANCO HOLDING recognizes as an obligation in the Consolidated Balance Sheet, on the issue date, the fair value of commitments for loans and financial guarantees. The fair value is generally represented by the fee charged to the customer. This amount is amortized over the term of the instrument and is recognized in the Consolidated Statement of Income under the heading Commissions and Banking Fees. After issue, if ITAÚ UNIBANCO HOLDING concludes based on the best estimate, that the expected credit loss in relation to the guarantee issued is higher that the fair value less accumulated amortization, this amount is replaced by a provision for loss. e) Investments in associates and joint ventures I – Associates Associates are companies in which the investor has a significant influence but does not hold control. Investments in these companies are initially recognized at cost of acquisition and subsequently accounted for using the equity method. Investments in associates and joint ventures include the goodwill identified upon acquisition, net of any cumulative impairment loss. II – Joint ventures ITAÚ UNIBANCO HOLDING has joint venture whereby the parties that have joint control of the arrangement have rights to the net assets. ITAÚ UNIBANCO HOLDING’s share in profits or losses of its associates and joint ventures after acquisition is recognized in the Consolidated statement of income. Its share of the changes in the share in other comprehensive income of corresponding stockholders’ equity of its associates and joint ventures is recognized in its own capital reserves. The cumulative changes after acquisition are adjusted against the carrying amount of the investment. When the ITAÚ UNIBANCO HOLDING’s share of losses in an associates and joint ventures is equal to or more than the value of its interest, including any other receivables, ITAÚ UNIBANCO HOLDING does not recognize additional losses, unless it has incurred any obligations or made payments on behalf of the associates and joint ventures. Unrealized profits on transactions between ITAÚ UNIBANCO HOLDING and its associates and joint ventures are eliminated to the extent of the interest of ITAÚ UNIBANCO HOLDING. Unrealized losses are also eliminated, unless the transaction provides evidence of impairment of the transferred asset. The accounting policies on associates and joint ventures entities are changed, as necessary, to ensure consistency with the policies adopted by ITAÚ UNIBANCO HOLDING. If its interest in the associates and joint ventures decreases, but ITAÚ UNIBANCO HOLDING retains significant influence or joint control, only the proportional amount of the previously recognized amounts in Other comprehensive income is reclassified in Income, when appropriate. f) Lessee operations ITAÚ UNIBANCO HOLDING leases mainly real estate properties (underlying assets) to carry out its business activities. The initial recognition occurs when the agreement is signed, in the heading Other Liabilities, which corresponds to the total future payments at present value as a contra entry to the Right- of-Use Assets, depreciated under the straight-line method for the lease term and tested half-yearly to identify possible impairment losses. The financial expense corresponding to interest on lease liabilities is recognized in the heading Interest and Similar Expense in the Consolidated Statement of Income. Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.21 VII – Loan Commitments and Financial Guarantees ITAÚ UNIBANCO HOLDING recognizes as an obligation in the Consolidated Balance Sheet, on the issue date, the fair value of commitments for loans and financial guarantees. The fair value is generally represented by the fee charged to the customer. This amount is amortized over the term of the instrument and is recognized in the Consolidated Statement of Income under the heading Commissions and Banking Fees. After issue, if ITAÚ UNIBANCO HOLDING concludes based on the best estimate, that the expected credit loss in relation to the guarantee issued is higher that the fair value less accumulated amortization, this amount is replaced by a provision for loss. e) Investments in associates and joint ventures I – Associates Associates are companies in which the investor has a significant influence but does not hold control.

Unrealized profits on transactions between ITAÚ UNIBANCO HOLDING and its associates and joint ventures are eliminated to the extent of the interest of ITAÚ UNIBANCO HOLDING. Unrealized losses are also eliminated, unless the transaction provides evidence of impairment of the transferred asset.

g) Fixed assets Fixed assets are recognized at cost of acquisition less accumulated depreciation, and adjusted for impairment, if applicable. Depreciation is calculated using the straight-line method and rates based on the estimated useful lives of these assets. These rates and other information are given in Note 13. The residual values and useful lives of assets are reviewed and adjusted, if appropriate, at the end of each period. ITAÚ UNIBANCO HOLDING reviews its assets in order to identify whether any indications of impairment exist. The recoverable amount of an asset is defined as the higher of its fair value less costs 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. Gains and losses on disposals of fixed assets are recognized in the Consolidated statement of income under Other income or General and administrative expenses. h) Intangible assets Intangible assets are non-physical assets, including software and other assets, and are initially recognized at cost. Intangible assets are recognized when they arise from legal or contractual rights, their costs can be reliably measured, and in the case of intangible assets not arising from separate acquisitions or business combinations, it is probable that future economic benefits may arise from their use. The balance of intangible assets refers to acquired assets or those internally generated. Intangible assets may have finite or indefinite useful lives. Intangible assets with finite useful lives are amortized using the straight-line method over their estimated useful lives. Intangible assets with indefinite useful lives are not amortized, but periodically tested in order to identify any impairment. ITAÚ UNIBANCO HOLDING semi-annually assesses its intangible assets in order to identify whether any indications of impairment exist, as well as possible reversal of previous impairment losses. If such indications are found, intangible assets are tested for impairment. The recoverable amount of an asset is defined as the higher of its fair value less costs 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. ITAÚ UNIBANCO HOLDING uses the cost model to measure its intangible assets after its initial recognition. A breakdown of intangible assets is given in Note 14. i) Assets held for sale Assets held for sale are recognized in the consolidated balance sheet under the line Other assets when they are actually repossessed or there is intention to sell. These assets are initially recorded at the lower of: (i) the fair value of the asset less the estimated selling expenses, or (ii) the carrying amount of the related asset held for sale. j) Income tax and social contribution There are two components of the 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 year end. 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 Other comprehensive income, such as: tax on fair value of financial assets measured at fair value through Other Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.22 g) Fixed assets Fixed assets are recognized at cost of acquisition less accumulated depreciation, and adjusted for impairment, if applicable.

comprehensive income, 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. Changes in tax legislation and rates are recognized in the Consolidated statement of income in the period in which they are enacted. Interest and fines are recognized in the Consolidated statement of income under General and administrative expenses. To determine the proper level of provisions for taxes to be maintained for uncertain tax positions, the approach applied, is that a tax benefit is recognized if it is more likely than not that a position can be sustained, under the assumptions for recognition, detailed in item 2.4 n. k) Insurance contracts and private pensions Insurance contracts are contracts under which ITAÚ UNIBANCO HOLDING accepts a significant insurance risk of the counterparty, by agreeing to compensate it if a specified uncertain future event adversely affects it. An insurance risk is significant only if the insurance event could cause ITAÚ UNIBANCO HOLDING to pay significant additional benefits in any scenario, other than those that do not have commercial substance. Additional benefits refer to amounts that exceed those that would be payable if no insured event occurred. Upon its first-time adoption of the IFRS, ITAÚ UNIBANCO HOLDING decided not to change its accounting policies for insurance contracts, which follow the accounting practices generally accepted in Brazil (“BRGAAP”). Although investment agreements with discretionary participation characteristics are financial instruments, they are treated as insurance contracts, as established by IFRS 4, as well as those transferring a significant financial risk. Once a contract is classified as an insurance contract, it remains as such until the end of its life, even if the insurance risk is significantly reduced during the period, unless all rights and obligations are extinguished or expire. Note 27 provides a detailed description of all products classified as insurance contracts. Private pension plans Contracts that provide for retirement benefits after an accumulation period (known as PGBL, VGBL and FGB), provide a guarantee at the commencement date of the contract, of the basis for calculating the retirement benefit (mortality table and minimum interest rates). The contracts specify the annuity rates and, therefore, the insurance risk is transferred to the issuer from the start. These contracts are classified as insurance contracts. Insurance premiums Insurance premiums are recognized upon issue of an insurance policy or over the period of the contracts in proportion to the amount of the insurance coverage. If there is evidence of impairment losses with respect to receivables for insurance premiums, ITAÚ UNIBANCO HOLDING recognizes a provision, sufficient to cover this loss, based on a risk analysis of realization of insurance premiums receivable with installments overdue for over 60 days. Reinsurance In the ordinary course of business, ITAÚ UNIBANCO HOLDING reinsures a portion of the risks underwritten, particularly property and casualty risks that exceed the maximum limits of responsibility that determine to be appropriate for each segment and product (after a study which considers size, experience, special features, and the capital necessary to support these limits). These reinsurance agreements allow the recovery of a portion of the losses from the reinsurer, although they do not release the insurer from the main obligation as direct insurer of the risks covered by the reinsurance.

ITAÚ UNIBANCO HOLDING mainly holds non-proportional contracts, which transfer part of responsibility to the reinsurance company for losses that will materialize after a certain level of claims in the portfolio. Reinsurance premiums of these contracts are accounted for under Other Assets, over the life of each contract. If there is any evidence of impairment loss, ITAÚ UNIBANCO HOLDING recognizes a provision when the default period exceeds 180 days from the registration of the request for fund of claims paid. Acquisition costs Acquisition costs include direct and indirect costs related to the origination of insurance. These costs are recorded directly in result as incurred, except for deferred acquisition costs (commissions paid for brokerage services, agency and prospecting efforts), which are recorded proportionally to the recognition of premium revenues, i.e. over the term of the insurance contract. Insurance Contract Liabilities Reserves for claims are established based on past experience, claims in process of payment, estimated amounts of claims incurred but not yet reported, and other factors relevant to the required reserve levels. Liability Adequacy Test ITAÚ UNIBANCO HOLDING tests liability adequacy by adopting current actuarial assumptions for future cash flows of all insurance contracts in force at the balance sheet date. Should the analysis show insufficiency, any shortfall identified will immediately be accounted for in income for the period. The assumptions used to conduct the liability adequacy test are detailed in Note 27. l) Post-employments benefits ITAÚ UNIBANCO HOLDING sponsors Defined Benefit Plans and Defined Contribution Plans, which are accounted for in accordance with IAS 19 – Benefits to Employees. ITAÚ UNIBANCO HOLDING is required to make contributions to government social security and labor indemnity plans, in Brazil and in other countries where it operates. 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 defined benefit obligations at the balance sheet date less the fair value of plan assets. The defined benefit obligations are calculated annually by an independent actuarial advisor using the projected unit credit method. Pension plans - Defined contribution For defined contribution plans, contributions to plans made by ITAÚ UNIBANCO HOLDING, through pension plan funds, are recognized as liabilities, with a counter-entry to expenses, when due. If contributions made exceed the liability for a service provided, it will be accounted for as an asset recognized at fair value, and any adjustments are recognized in Stockholders’ equity, under Other comprehensive income, in the period when they occur. Other post-employment benefit obligations Like defined benefit pension plans, these obligations are value annually by independent, qualified actuaries, and 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, under Other comprehensive income, in the period when they occurred.

m) Share-based payments Share-based payments are booked for the value of equity instruments granted, which may be shares or stock options according to the plan, based on their fair value at the grant date. This cost is recognized during the vesting period of the right to exercise the instruments. The total amount to be expensed is determined by reference to the fair value of the equity instruments excluding the impact of any service commissions and fees and non-market performance vesting conditions (in particular when an employee remains with the company for specific period of time). n) Provisions, contingent assets and contingent liabilities Contingent assets and liabilities are possible rights and obligations arising from past events for which realization depends on uncertain future events. Contingent assets are not recognized in the Consolidated Financial Statements, except when the Management of ITAÚ UNIBANCO HOLDING considers that realization is virtually certain. In general this is the case of lawsuits with favorable rulings, in final and unappealable judgments, or 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: liabilities are recognized in the consolidated balance sheet under Provisions; • Possible: disclosed in the Consolidated Financial Statements, but no provision is recorded; • Remote: require neither a provision nor disclosure. The amount of court deposits is adjusted in accordance with current legislation. o) Capital Common and preferred shares, which for accounting purposes are equivalent to common shares but without voting rights are classified in Stockholders’ equity. The additional costs directly attributable to the issue of new shares are included in Stockholders’ equity as a deduction from the proceeds, net of taxes. p) Treasury shares Common and preferred shares repurchased are recorded in Stockholders’ equity under Treasury shares at their average purchase price. Shares that are subsequently sold, such as those sold to grantees under our share-based payment scheme, are recorded as a reduction in treasury shares, measured at the average price of treasury stock held at that date. The difference between the sale price and the average price of the treasury shares is recorded as a reduction or increase in Additional paid-in capital. The cancellation of treasury shares is recorded as a reduction in Treasury shares against Appropriated reserves, at the average price of treasury shares at the cancellation date. q) Dividends and interest on capital Minimum dividend amounts established in the bylaws are recorded as liabilities at the end of each year. Any other amount above the mandatory minimum dividend is accounted for as a liability when approved by of the Board of Directors.

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. The total value of margins pledged in guarantee by ITAÚ UNIBANCO HOLDING was R$ 22,857 (R$ 15,823 at 12/31/2019) and was basically comprised of government securities.

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.

IV - Credit derivatives ITAÚ UNIBANCO HOLDING 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 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.

CDS (credit default swap) is 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.

Note 7 – Hedge accounting There are three types of hedge relations: Fair value hedge, Cash flow hedge and Hedge of net investment in foreign operations. In hedge accounting, the groups of risk factors measured by ITAÚ UNIBANCO HOLDING are: • Interest Rate: Risk of loss in transactions subject to interest rate variations; • Currency: Risk of loss in transactions subject to foreign exchange variation. The structure of risk limits is extended to the risk factor level, where specific limits aim at improving the monitoring and understanding process, as well as avoiding concentration of these risks. The structures designed for interest rate and exchange rate categories take into account total risk when there are compatible hedging instruments. In certain cases, management may decide to hedge a risk for the risk factor term and limit of the hedging instrument. The other risk factors hedged by the institution are shown in Note 32. To protect cash flows and fair value of instruments designated as hedged items, ITAÚ UNIBANCO HOLDING uses derivative financial instruments and financial assets. Currently, Futures Contracts, Options, NDF (non- deliverable forwards), Forwards, Swaps and Financial Assets are used. ITAÚ UNIBANCO HOLDING manages risks through the economic relationship between hedging instruments and hedged items, where the expectation is that these instruments will move in opposite directions and in the same proportion, with the purpose of neutralizing risk factors. The designated coverage ratio is always 100% of the risk factor eligible for coverage. Sources of ineffectiveness are in general related to the counterparty’s credit risk and possible mismatches of terms between the hedging instrument and the hedged item. a) Cash flow hedge The cash flow hedge strategies of ITAÚ UNIBANCO HOLDING consist of hedging exposure to variations in cash flows, in interest payment and currency exposure which are attributable to changes in interest rates on recognized and unrecognized assets and liabilities. ITAÚ UNIBANCO HOLDING applies cash flow hedge strategies as follows: Interest rate risks: • Hedge of time deposits and repurchase agreements: to hedge fluctuations in cash flows from interest payments resulting from changes in the DI interest rate, through futures contracts; • Hedge of asset transactions: to hedge fluctuations in cash flows from interest receipts resulting from changes in the DI rate, through futures contracts; • Hedge of assets denominated in UF*: to hedge fluctuations in cash flows of interest receipts resulting from changes in the UF*, through swap contracts; • Hedge of Funding: to hedge fluctuations in cash flows of interest payments resulting from changes in the TPM* rate and foreign exchange, through swap contracts; • Hedge of loan operations: to hedge fluctuations in cash flows of interest receipts resulting from changes in the TPM* rate, through swap contracts; • Hedge of repurchase agreements: to hedge fluctuations in cash flows from interest received on changes in Selic (benchmark interest rate), through futures contracts; • Hedging of expected highly probable transactions: hedging the risk of variation in the amount of the commitments assumed when resulting from variation in the exchange rates. *UF – Chilean unit of account / TPM – Monetary policy rate ITAÚ UNIBANCO HOLDING does not use the qualitative method to evaluate the effectiveness or to measure the ineffectiveness of such strategies. For cash flow hedge strategies, ITAÚ UNIBANCO HOLDING uses the hypothetical derivative method. This method is based on a comparison of the change in the fair value of a hypothetical derivative with terms identical to the critical terms of the variable-rate liability, and this change in the fair value is considered a proxy of the present value of the cumulative change in the future cash flow expected for the hedged liability.

b) Hedge of net investment in foreign operations ITAÚ UNIBANCO HOLDING’s strategies for net investments in foreign operations consist of hedging the exposure in the functional currency of the foreign operation against the functional currency of head office, by contracting DDI futures, NDF and financial assets. The risk hedged in this type of strategy is the currency risk. ITAÚ UNIBANCO HOLDING does not use the qualitative method to evaluate the effectiveness or to measure the ineffectiveness of these strategies. Instead, ITAÚ UNIBANCO HOLDING uses the Dollar Offset Method, which is based on a comparison of the change in fair value (cash flow) of the hedging instrument, attributable to changes in the exchange rate and the gain (loss) arising from variations in exchange rates on the amount of investment abroad designated as the object of the hedge. 03/31/2020 Hedged item Hedge instrument (2) Variation in fair value Book Value Strategies Variation in value Foreign currency Notional used to calculate recognized in Other convertion reserve amount hedge Assets Liabilities comprehensive income ineffectiveness Foreign exchange risk (1) Hedge of net investment in foreign operations - 16,476 (12,063) (12,063) 24,946 (12,066) Total - 16,476 (12,063) (12,063) 24,946 (12,066) 12/31/2019 Hedged item Hedge instrument (2) Variation in fair value Book Value Strategies Variation in value Foreign currency Notional used to calculate recognized in Other convertion reserve amount hedge Assets Liabilities comprehensive income ineffectiveness Foreign exchange risk (1) Hedge of net investment in foreign operations - 14,396 (7,217) (7,217) 16,947 (7,220) Total - 14,396 (7,217) (7,217) 16,947 (7,220) (1) Hedge instruments consider the gross tax position; (2) Amounts recorded under heading Derivatives - Hedge of investments in foreign operation. 03/31/2020 (*) Variations in fair Variation in the value Hedge Amount reclassified Book Value Hedge instruments Notional value used to recognized in Other ineffectiveness from foreign currency amount calculate hedge comprehensive recognized in convertion reserve Assets Liabilities ineffectiveness income income into income Foreign exchange risk Futures 44,203 - 120 (19,172) (19,135) (37) - Forward (3,950) 3,960 - 407 380 27 - NDF (15,203) - 336 6,436 6,427 9 - Financial Assets (104) 104 - 263 265 (2) - Total 24,946 4,064 456 (12,066) (12,063) (3) - 12/31/2019 Variations in fair Variation in the value Hedge Amount reclassified (*) Book Value Hedge instruments Notional value used to recognized in Other ineffectiveness from foreign currency amount calculate hedge comprehensive recognized in convertion reserve Assets Liabilities ineffectiveness income income into income Foreign exchange risk 32,966 228 - (12,329) (12,292) (37) - Futures Forward (2,990) 2,977 - 408 381 27 - NDF (11,525) 260 - 4,443 4,434 9 - Financial Assets (1,504) 1,523 - 258 260 (2) - 16,947 4,988 - (7,220) (7,217) (3) - Total (*) Amounts recorded under heading Derivatives.

c) Fair value hedge The fair value hedging strategy of ITAÚ UNIBANCO HOLDING consists of hedging the exposure to variations in fair value on the receipt and payment of interest on recognized assets and liabilities. ITAÚ UNIBANCO HOLDING applies fair value hedges as follows: Interest rate risk: • To protect the risk of variation in the fair value of receipt and payment of interest resulting from variations in the fair value of the variable rates involved, by contracting swaps and futures. ITAÚ UNIBANCO HOLDING does not use the qualitative method to evaluate the effectiveness or to measure the ineffectiveness of these strategies. Instead, ITAÚ UNIBANCO HOLDING uses the percentage approach and dollar offset method: • The percentage approach is based on the calculation of change in the fair value of the revised estimate for the hedged position (hedged item) attributable to the protected risk versus the change in the fair value of the derivative hedging instrument. • The dollar offset method is based on the difference between the variation in the fair value of the hedging instrument and the variation in the fair value of the hedged item attributed to changes in the interest rate. The effects of hedge accounting on the financial position and performance of ITAÚ UNIBANCO HOLDING are presented below: 03/31/2020 (2) Hedged Item Hedge Instruments (1) Variation in fair Fair value Book Value Strategies Variation in fair value Notional value used to recognized in amount calculate hedge income Assets Liabilities Assets Liabilities ineffectiveness Interest rate risk Hedge of loan operations 9,537 - 9,921 - 384 9,537 (392) Hedge of funding - 8,513 - 9,361 (848) 8,513 846 Hedge of securities at fair value through other 7,779 - 8,165 - 386 7,892 (386) comprehensive income Total 17,316 8,513 18,086 9,361 (78) 25,942 68 12/31/2019 Hedged Item Hedge Instruments (1) Variation in fair Fair value Book Value Strategies Variation in fair value Notional value used to recognized in amount calculate hedge income Assets Liabilities Assets Liabilities ineffectiveness Interest rate risk Hedge of loan operations 7,386 - 7,642 - 256 7,386 (264) Hedge of funding - 7,436 - 8,195 (759) 7,436 775 Hedge of securities at fair value through other 4,482 - 4,574 - 92 4,609 (85) comprehensive income Total 11,868 7,436 12,216 8,195 (411) 19,431 426 (1) Amounts recorded under heading Deposits, Securities, Funds from Interbank Markets and Loan and Lease Operation.

a) Main Actuarial Assumptions Actuarial assumptions of demographic and financial nature should reflect the best estimates about the variables that determine the post-employment benefit obligations. The main demographic assumptions comprise: mortality table and turnover of active participants, while the main financial assumptions include: discount rate, future salary increases, growth of plan benefits and inflation. 03/31/2020 03/31/2019 (1) Discount rate 7.64% p.a. 9.72% p.a.

Growth of the pension fund benefits 4.00 % p.a. 4.00 % p.a. Inflation 4.00 % p.a. 4.00 % p.a. Actuarial method Projected Unit Credit Projected Unit Credit (1) Determined based on market yield relating to National Treasury Notes (NTN-B) and compatible with the economic scenario observed on the balance sheet closing date, considering the volatility of interest market and models used. (2) Correspond to those disclosed by SOA – Society of Actuaries , that reflect a 10% increase in the probabilities of survival regarding the respective basic tables. (3) Updated to the new expectation of mass behavior. Retired plans sponsored by foreign subsidiaries - Banco Itaú (Suisse) S.A., Itaú CorpBanca Colombia S.A. and PROSERV - Promociones y Servicios S.A. de C.V. - are structured as Defined Benefit modality and adopt actual assumptions adequate to masses of participants and the economic scenario of each country. b) Risk Management The EFPCs sponsored by ITAÚ UNIBANCO HOLDING are regulated by the National Council for Complementary Pension (CNPC) and PREVIC, has an Executive Board, Advisory and Tax Councils. Benefits offered have long-tem characteristics and the main factors involved in the management and measurement of their risks are financial risk, inflation risk and demographic risk. - Financial Risk – the actuarial liability is calculated by adopting a discount rate different 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. In the event deficit is verified in the concession period above the settlement limits set forth by the legislation in force, a debt agreement is entered into with the sponsor with financial guarantees.

Note 27 – Insurance contracts and private pension ITAÚ UNIBANCO HOLDING, through its subsidiaries, offers to the market insurance and private pension products, with the purpose of assuming risks and restoring the economic balance of the insured’s assets. Products are offered through insurance brokers (independent and captive brokers), Itaú Unibanco’s electronic channels and branches, in compliance with the regulatory requirements, of the National Council of Private Insurance – CNSP and the Superintendence of Private Insurance - SUSEP. I – Insurance A contract entered into by the parties to protect the customer’s assets, upon payment of a premium, by means of replacement or pre-established financial compensation, against damage their property or their person. As backing, ITAÚ UNIBANCO HOLDING insurance companies set up technical reserves, through specialized areas within the conglomerate, with the objective of indemnifying policyholders’ losses in the event of claims of insured risks. The insurance risks sold by ITAÚ UNIBANCO HOLDING’s insurance companies are divided into property and casualty insurance, covering loss, damage or liabilities for assets or persons, and life insurance that includes coverage for death and personal accidents. II – Private pension Designed to ensure the maintenance of the quality of life of participants, as a supplement to the government plans, through long term investments, private pension products are divided into three major groups: • PGBL – Free Benefit Generating Plan: The main objective of this plan is the accumulation of financial resources, but it can be purchased with additional risk coverage. Recommended for customers that file the full version of the income tax return, because they can deduct contributions paid for tax purposes up to 12% of their annual taxable gross income. • VGBL - Free Benefit Generating Life Plan: This is insurance structured as a pension plan. Its taxation differs from the PGBL; in this case, the tax basis is the earned income. • FGB – Benefit Generator Fund: This is a pension plan with minimum income guarantee, and possibility of receiving earnings from asset performance. Although there are plans still in existence, they are no longer sold. III – Technical provision for insurance and private pensions The technical provisions for insurance and private pensions are recognized according to the technical notes approved by SUSEP and criteria established by current legislation, as follows: • Provision for unearned premiums (PPNG) - this provision is recognized, based on insurance premiums, to cover amounts payable for future claims and expenses. In the calculation, the term to maturity of risks assumed and issued and risks in effect but not issued (PPNG-RVNE) in the policies or endorsements of contracts in force is taken pro rata on a daily basis; • Provision for unsettled claims (PSL) - this provision is recognized to cover expected amounts to reported and unpaid claims, including administrative and judicial claims. It includes amounts related to indemnities, reserve funds and past-due income, all gross of reinsurance operations and net of coinsurance operations, as applicable. When necessary, it must cover adjustments for IBNER (claims incurred but not sufficiently reported) for the total of claims reported but not yet paid, a total which may change during the process up to final settlement; • Provision for claims incurred and not reported (IBNR) - this provision is recognized for the coverage of expected amount for settlement of claims incurred but not reported up to the calculation base date, including administrative and judicial claims. It includes amounts related to indemnities, reserve funds and income, all gross of reinsurance operations and net of coinsurance operations; • Mathematical provisions for benefits to be granted (PMBAC) - recognized for the coverage of commitments assumed to participants or policyholders, based on the provisions of the contract, while the event that gives rise to the benefit and/or indemnity has not occurred; Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.78 Note 27 – Insurance contracts and private pension ITAÚ UNIBANCO HOLDING, through its subsidiaries, offers to the market insurance and private pension products, with the purpose of assuming risks and restoring the economic balance of the insured’s assets.

VII - Liability Adequacy Test ITAÚ UNIBANCO HOLDING tests for Liability Adequacy half-yearly, by comparing the amount recognized for its technical reserves with the current estimate of cash flow of its future obligations. The estimate should include all cash flows related to the business, which is the minimum requirement for carrying out the adequacy test. The Liability Adequacy Test did not indicate significant insufficiency in 2019. The assumptions used in the test are periodically reviewed and are based on best practices and an analysis of subsidiaries’ experience, thus representing the best estimates for cash flow projections. Methodology and test grouping Specifically for insurance products, cash flows were projected using the method known as the run-off triangle for quarterly frequency periods. For pension products, cash flows for the deferral and concession phases are tested separately. The risk grouping criteria include groups subject to similar risks that are jointly managed as a single portfolio. Demographic tables Demographic tables are instruments to measure the demographic risk represented by the probability of death, survival or disability of a participant. For death and survival estimates, the latest Brazilian Market Insurer Experience tables (BR-EMS) are used, adjusted according to Scale G life expectancy development, and the Álvaro Vindas table is used to estimate benefit requests for disability. Risk-free interest rate The relevant risk-free forward interest-rate structure (ETTJ) is an indicator of the pure time value of money used to price the set of projected cash flows. The ETTJ was obtained from the curve of securities deemed to be credit risk free, available in the Brazilian financial market and determined by ITAÚ UNIBANCO HOLDING using its own method, plus a spread, which takes into account the impact of the market result of securities classified as Financial assets at amortized cost in the Guarantee assets portfolio. Annuity conversion rate The annuity conversion rate represents the expected conversion of balances accumulated by participants in retirement benefits. The decision by participants convert into an annuity is influenced by behavioral, economic and tax factors. Other assumptions Related expenses, cancellations and partial redemptions, future additions and contributions, are among the assumptions that affect the estimate of projected cash flows since they represent expenses and income arising from insurance agreements assumed.

Note 28 – 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.

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.

The methods and assumptions used to estimate the fair value are defined below: a) Cash, Central Bank compulsory deposits, Securities purchased under agreements to resell and Securities sold under repurchase agreements – The carrying amounts for these instruments are close to their fair values. b) Interbank deposits, Deposits, Interbank and Institutional Market Funds – they are calculated by discounting estimated cash flows at market interest rates. c) Securities and Derivatives – 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 determined based on the interest rates provided by brokers. The fair values of corporate debt securities are calculated by discounting estimated cash flows at market interest rates. The fair values of shares are based on the prices quoted in the market. The fair values of derivative financial instruments were determined as follows: • Swaps: The cash flows are discounted to present value based on yield curves that reflect the appropriate risk factors, mainly following swap prices on B3 for derivatives, of Brazilian government securities in the secondary market or derivatives and securities traded abroad. These yield curves may be used to obtain the fair value of currency swaps, interest rate swaps and swaps based on other risk factors (commodities, stock exchange indices, etc.). • Futures and forwards: Quotations on exchanges or using criteria identical to those applied to swaps. • Options: Determined through mathematical models, such as Black-Scholes, using data, in general from Bloomberg, for implicit volatility, interest rate yield curve and fair value of the underlying asset. Current market prices of options are used to compute the implicit volatilities. • Credit Derivatives: They are inversely related to the probability of default (PD) in a financial instrument subject to credit risk. The process of adjusting the market price of these spreads is based on the differences between the yield curves with and without credit risk. d) Loans and financial leases – 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. e) Other financial assets / liabilities – primarily composed of receivables from credit card issuers, deposits in guarantee for contingent liabilities, provisions and legal obligations and trading and intermediation of securities. The carrying amounts for these assets/liabilities substantially approximate to their fair values, since they principally represent amounts to be received in the short term from credit card holders and to be paid to credit card issuers, court deposits (indexed to market rates) made by ITAÚ UNIBANCO HOLDING to secure lawsuits or very short-term receivables (generally with a maturity of approximately 5 business days). All of these items represent assets / liabilities without significant associated market, credit or liquidity risks. Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. An active market is a market in which transactions for the asset or liability being measured occur often enough and with sufficient volume to provide pricing information on an ongoing basis.

Level 2: Input that is not observable for the asset or liability either directly or indirectly. Level 2 generally includes: (i) quoted prices for similar assets or liabilities in active markets; (ii) quoted prices for identical or similar assets or liabilities in markets that are not active, that is, markets in which there are few transactions for the asset or liability, the prices are not current, or quoted prices vary substantially either over time or among market makers, or in which little information is released publicly; (iii) inputs other than quoted prices that are observable for the asset or liability (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, etc.); (iv) inputs that are mainly derived from or corroborated by observable market data through correlation or by other means. Level 3: Inputs are not observable for the asset or liability. Unobservable information is used to measure fair value to the extent that observable information is not available, thus allowing for situations in which there is little, or no market activity for the asset or liability at the measurement date. Financial assets at fair value through profit or loss, including Derivatives, and at fair value through other comprehensive income: Level 1: Highly-liquid securities with prices available in an active market and derivatives traded on stock exchanges. This classification level includes most of the Brazilian government securities, other foreign government securities, shares and debentures traded on stock exchanges and other securities traded in an active market. Level 2: When pricing information is not available for a specific security, valuation is usually based on prices quoted in the market for similar instruments, pricing information obtained from pricing services, such as Bloomberg, Reuters and brokers (only when the prices represent actual transactions) or discounted cash flows, which use information for assets actively traded in an active market. These securities are classified at Level 2 of the fair value hierarchy and consist of certain Brazilian government securities, debentures, some government securities quoted in a less liquid market than for Level 1, and some share prices in investment funds. Derivatives included in Level 2 are credit default swaps, cross-currency swaps, interest rate swaps, simple options and some forwards, since information adopted by pricing models is immediately observable in actively quoted markets. The models used for these instruments are Black-Scholes, Garman & Kohlhagen, Monte Carlo and discounted cash flow. ITAÚ UNIBANCO HOLDING does not hold positions in alternative investment funds or private equity funds. Level 3: When there is no pricing information in an active market, ITAÚ UNIBANCO HOLDING uses internally developed models, from curves generated according to a proprietary model. Level 3 classification includes some Brazilian government and private securities falling due after 2025 which are not usually traded in an active market. Derivatives with fair values classified in Level 3 of the fair value hierarchy are composed of exotic options, certain swaps indexed to non-observable inputs, and swaps with other products, such as swap with options or with verification, credit derivatives and futures of certain commodities. All the above methods may result in a fair value that is not indicative of the net realizable value or future fair values. However, ITAÚ UNIBANCO HOLDING believes that all the method used are appropriate and consistent with other market participants. Moreover, the adoption of different methods or assumptions to estimate fair value may result in different fair value estimates at the balance sheet date.

Measurement of Level 2 fair value based on pricing services and brokers To ensure that the fair value of these instruments is properly classified as Level 2, in-house analysis of information received are conducted, so as to understand the nature of inputs used by the service provider. Prices provided by pricing services that meet the following requirements are considered Level 2: input is immediately available, regularly distributed, provided by sources actively involved in significant markets and it is not proprietary. For financial instruments classified as Level 2, the pricing service or brokers were used to price securities substantially represented by: • Debentures: When available, we use price information for transactions recorded in the Brazilian Debenture System (SND), an electronic platform operated by B3, which provides multiple services for transactions involving debentures in the secondary market. Alternatively, prices of debentures provided by ANBIMA are used. Its methodology includes obtaining, on a daily basis, illustrative non-binding prices from a group of market players deemed to be significant. Such information is subject to statistical filters intended to eliminate outliers. • Financial Credit Bills: In order to mark Financial Credit Bills to market, it is necessary to calculate its future value by projecting the notional issue value and its yields established by contract (fixed rate, floating rate or price index) and discounting the fixed curve in reais, obtained through DI Futures prices traded on B3. • Global and corporate securities: The pricing process for these securities consists of capturing from 2 to 8 quotes from Bloomberg, depending on the asset. The method then compares the highest purchase prices and the lowest sale prices of trades provided by Bloomberg for the last day of the month. These prices are compared with information from purchase orders that the Institutional Treasury of ITAÚ UNIBANCO HOLDING provides to Bloomberg. Should the difference between them be lower than 0.5%, the average price of Bloomberg is used. If it is higher than 0.5% or if the Institutional Treasury does not provide information on this specific security, the average price gathered directly from other banks is used. The Institutional Treasury price is used as a reference only and never in the computation of the final price. Level 3 recurring fair value measurements The departments in charge of defining and applying the pricing models are segregated from the business areas. The models are documented, submitted to validation by an independent area and approved by a specific committee. The daily 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. 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. For swaps, the indexers for both legs are analyzed. There are some cases in which the input periods are shorter than the maturity of the derivative.

Sensitivity analysis of Level 3 operations The fair value of financial instruments classified in Level 3 is measured through valuation techniques based on correlations and associated products traded in active markets, internal estimates and internal models. 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: Sensitivity – Level 3 Operations 03/31/2020 12/31/2019 Impact Impact Market risk factor groups Scenarios Stockholders' Stockholders' Income Income equity equity I (1.1) (0.1) ( 0.9) ( 0.0) Interest rates II (27.5) (2.2) ( 23.3) ( 0.3) III (54.6) (4.3) ( 46.1) ( 0.6) - - - - I Shares II - - - - I (19.2) - ( 22.6) - Nonlinear II ( 32.5) - ( 43.2) - The following scenarios are used to measure sensitivity: Interest rate 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. Shares 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. Nonlinear 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. Note 29 - Contingent Assets and Liabilities, Provisions and Legal Obligations In the ordinary course of its business, ITAÚ UNIBANCO HOLDING 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: The criteria to quantify of provisions for contingencies are adequate in relation to the specific characteristics of civil, labor and tax lawsuits portfolios, as well as other risks, taking into consideration the opinion of its legal advisors, the nature of the lawsuits, the similarity with previous lawsuits and the prevailing previous court decisions. A provision is recognized whenever the loss is classified as probable. Legal liabilities arise from lawsuits filed to discuss the legality and unconstitutionality of the legislation in force, being subject to an accounting provision.

I- 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, despite having complied with the rules in force at the time, is a defendant in lawsuits filed by individuals referring to payment of inflation adjustments to savings accounts resulting from economic plans implemented in the 1980s and the 1990s, as well as in collective lawsuits filed by: (i) consumer protection associations; and (ii) the Public Attorney’s Office, on behalf of the savings accounts holders. ITAÚ UNIBANCO HOLDING recognizes provisions upon receipt of summons, and when individuals demand the enforcement of a ruling handed down by the courts, using the same criteria as for provisions for individual lawsuits. 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 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 period, in March 2020, the parties signed an amendment to the agreement instrument to extend the adhesion period for another 60 months and, thus, to cover a greater number of savers and, consequently, increase the termination of lawsuits. For effectiveness and validity this amendment, it needs to be approved by the Federal Supreme Court (STF), which is expected to occur in the second quarter of 2020. II- Labor claims Provisions for 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 is reassessed taking into account court rulings. Provisions for 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. III- 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.

It includes financing and credit offers made outside the branch network, in addition to credit cards and payroll loans. • Wholesale Banking It comprises products and services offered to middle-market companies, high net worth clients (Private Banking), and the operation of Latin American units and Itaú BBA, which is the unit responsible for business with large companies and Investment Banking operations. • Activities with the Market + Corporation Basically corresponds to the result arising from capital surplus, subordinated debt surplus and the net balance of tax credits and debits. It also includes the financial margin on market trading, Treasury operating costs, and equity in earnings of companies not included in either of the other segments. a) Basis of Presentation Segment information is based on the reports used by senior management to assess performance and to make decisions about allocation of funds for investment and other purposes. These reports use a variety of information for management purposes, including financial and non-financial information supported by bases different from information prepared according to accounting practices adopted in Brazil. The main indicators used for monitoring business performance are Recurring Income, and Return on Economic Capital allocated to each business segment. Information by segment has been prepared in accordance with accounting practices adopted in Brazil and is adjusted by the items below: Allocated capital: The statements for each segment consider capital allocation based on a proprietary model and consequent impacts on results arising from this allocation. This model includes the following components: Credit risk, operating risk, market risk and insurance underwriting risk. Income tax rate: We take the total income tax rate, net of the tax effect from the payment of interest on capital, for the Retail Banking, Wholesale Banking and Activities with the Market + Corporation. The difference between the income tax amount calculated by segment and the effective income tax amount, as stated in the consolidated financial statements, is allocated to the Trading + Institutional column. • Reclassification and application of managerial criteria The managerial statement of income was used to prepare information per segment. These statements were obtained based on the statement of income adjusted by the impact of non-recurring events and the managerial reclassifications in income. The main reclassifications between the accounting and managerial results are: Operating revenues: Considers the opportunity cost for each operation. The financial statements were adjusted so that the stockholders' equity was replaced by funding at market price. Subsequently, the financial statements were adjusted to include revenues related to capital allocated to each segment. The cost of subordinated debt and the respective remuneration at market price were proportionally allocated to the segments, based on the economic capital allocated.

Note 32 – Risk and Capital Management a) Corporate Governance ITAÚ UNIBANCO HOLDING invests in sound processes for risk and capital management that permeates the whole institution and are the basis of all strategic decisions to ensure business sustainability. These processes are aligned with the guidelines of the Board of Directors and Executive which, through collegiate bodies, define the global objectives expressed as targets and limits for the business units that manage risk. Control and capital management units, in turn, support ITAÚ UNIBANCO HOLDING’s management by monitoring and analyzing risk and capital. The Board of Directors is the main body responsible for establishing guidelines, policies and approval levels for risk and capital management. The Capital and Risk Management Committee (CGRC), in turn, is responsible for supporting the Board of Directors in managing capital and risk. At the executive level, collegiate bodies, presided over by the Chief Executive Officer (CEO) of ITAÚ UNIBANCO HOLDING, are responsible for capital and risk management, and their decisions are monitored by the CGRC. Additionally, ITAÚ UNIBANCO HOLDING has collegiate bodies with capital and risk management responsibilities delegated to them, chaired by the Executive Vice-President of the Risk and Finance Department (ARF). To support this structure, ARF has departments to ensure, on an independent and centralized basis, that the institution’s risks and capital are managed in compliance with defined policies and procedures. b) Risk Management Risk Appetite The risk appetite of ITAÚ UNIBANCO HOLDING is based on the Board of Director’s statement: “We are a universal bank, operating mainly in Latin America. Supported by our risk culture, we insist on with strict ethical standards and regulatory compliance, seeking high and increasing returns, with low volatility, through lasting relationships with our customers, accurate risk pricing, widespread funding and proper use of capital.” Based on this statement, five dimensions have been defined, 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. The five dimensions of risk appetite are: • Capitalization: establishes that ITAÚ UNIBANCO HOLDING must have capital sufficient to face any serious recession period or a stress event without the need to adjust its capital structure under unfavorable circumstances. It is monitored by tracking ITAÚ UNIBANCO HOLDING’s capital ratios, both in normal and stress scenarios, and of the ratings of the institution's debt issues. • Liquidity: establishes that the liquidity of ITAÚ UNIBANCO HOLDING must withstand long periods of stress. It is monitored tracking liquidity indicators. • Composition of results: defines that business will be focused primarily on Latin America, where ITAÚ UNIBANCO HOLDING has a diversified base of customers and products, with low appetite for income volatility or for high risk. This dimension comprises aspects related to business, profitability, market risk and credit risk. By adopting exposure concentration limits, such as industry sectors, counterparty quality, countries and geographical regions and risk factors, these monitored metrics are intended to ensure well-adjusted portfolios, low income volatility and business sustainability.

ITAÚ UNIBANCO HOLDING is committed to doing business that is good both for the customer and the institution itself; • Risk Culture: ITAÚ UNIBANCO HOLDING’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’s acts and assumes risks in business which it knows and understands, avoiding those with which it is unfamiliar or that do not offer a competitive edge, and carefully assessing the risk-return ratio; • Diversification: ITAÚ UNIBANCO HOLDING 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 to be an agile bank, with a robust and stable infrastructure enabling us to offer top quality services; • Ethics and respect for regulations: for ITAÚ UNIBANCO HOLDING, ethics is non-negotiable, 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 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 guidelines, helping employees to conscientiously understand, identify, measure, manage and mitigate risks. 1. Credit risk The possibility of losses arising from failure by a borrower, issuer or counterparty to meet their financial obligations, the impairment of a loan due to downgrading of the risk rating of the borrower, the issuer or the counterparty, a decrease in earnings or remuneration, advantages conceded on renegotiation or the costs of recovery. There is a credit risk control and management structure, centralized and independent from the business units, that provides for operating limits and risk mitigation mechanisms, and also establishes processes and tools to measure, monitor and control the credit risk inherent in all products, portfolio concentrations and impacts of potential changes in the economic environment. The credit policy of ITAÚ UNIBANCO HOLDING is based on internal criteria such as: classification of customers, portfolio performance and changes, default levels, rate of return and economic capital allocated, and external factors such as interest rates, market default indicators, inflation, changes in consumption, and so on.

For personal customers and small and middle-market companies, credit rating is based on statistical application models (at the early stages of the relationship with a customer) and behavior score (used for customers with which ITAÚ UNIBANCO HOLDING already has a relationship). For large companies, the rating is based on information such as economic and financial condition of the counterparty, their cash-generating capability, the economic group to which they belong, and the current and prospective situation of the economic sector in which they operate. Credit proposals are analyzed on a case by case basis, through an approval-level mechanism. ITAÚ UNIBANCO HOLDING strictly controls the credit exposure of customers and counterparties, taking action to address situations in which the current exposure exceeds what is desirable. For this purpose, measures provided for in loan agreements are available, such as accelerated maturity or a requirement for additional collateral. 1.1 Collateral and policies for mitigating credit risk ITAÚ UNIBANCO HOLDING uses guarantees to increase its capacity for recovery in operations exposed to credit risk. The guarantees may be personal, secured, legal structures with mitigating power and offset agreements. For collateral to be considered instruments that mitigate credit risk, they must comply with the requirements and standards that regulate them, both internal and external ones, and they must be legally valid (effective), enforceable, and assessed on a regular basis. ITAÚ UNIBANCO HOLDING also uses credit derivatives, to mitigate credit risk of its portfolios of loans and securities. These instruments are priced based on models that use the fair value of market inputs, such as credit spreads, recovery rates, correlations and interest rates. 1.2 Policy for Provisioning and Economic Scenarios Both the credit risk and the finance areas are responsible for defining the methods used to measure expected loan losses and for periodically assessing changes in the provision amounts. These areas monitor the trends observed in provisions for expected credit losses by segment, in addition to establishing an initial understanding of the variables that may trigger changes in the allowance for loan losses, the probability of default (PD) or the loss given default (LGD). Once the trends have been identified and an initial assessment of the variables has been made at the corporate level, the business areas are responsible for further analyzing these trends in more detail and for each segment, in order to understand the underlying reasons for the trends and to decide whether changes are required in credit policies. Provisions for expected losses take into account the expected risk linked to contracts with similar characteristics and in anticipation of signs of deterioration, over a loss horizon suitable for the remaining period of the contract to maturity. For contracts of products with no determined termination date, average results of deterioration and default are used to determine the loss horizon. Additionally, information on economic scenarios and public data with internal projections are used to determine and adjust the expected credit loss in line with expected macroeconomic realities. 1.3 Classification of Stages of Credit Impairment ITAÚ UNIBANCO HOLDING uses customers’ internal information, statistic models, days of default and quantitative analysis in order to determine the credit status of portfolio agreements. Rules for changing stages take into account lower and higher internal limits (quantitative criteria), in addition to the relative variation in the rating since the initial recognition. Information on days of delay, used on an absolute basis, is an important factor for the classification of stages, and after a certain credit status has been defined for an agreement, it is classified in one of the three stages of credit deterioration. Based on this classification, rules for measuring expected credit loss in each stage are used, as described in Note 2.4d.

1.4.4 Repossessed assets Assets received from the foreclosure of loans, including real estate, are initially recorded at the lower of: (i) the fair value of the asset less the estimated selling expenses, or (ii) the carrying amount of the loan. Further impairment of assets is recorded as a provision, with a corresponding charge to income. The maintenance costs of these assets are expensed as incurred. The policy for sales of these assets includes periodic auctions that are announced to the market in advance, and provides that the assets cannot be held for more than one year, as stipulated by BACEN. Total assets repossessed in the period were R$ 99 (R$ 390 at 12/31/2019), mainly composed of real estate. 2. 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. ITAÚ UNIBANCO HOLDING’s market risk management strategy is aimed at balancing corporate business goals, taking into account, among other things, political, economic and market conditions, the portfolio profile and the ability to operate in specific markets. Market risk is controlled by an area independent from the business areas, which is responsible for the daily activities of (i) risk measurement and assessment, (ii) monitoring of stress scenarios, limits and alerts, (iii) application, analysis and testing of stress scenarios, (iv) risk reporting to those responsible within the business areas, in compliance with the governance of ITAÚ UNIBANCO HOLDING, (v) monitoring of actions required to adjust positions and risk levels to make them realistic, and (vi) providing support for the safe launch of new financial products. The National Monetary Council (CMN) has regulations governing the segregation of exposure to market risk into risk factors, such as: interest rate, exchange rate, equities and commodities. Brazilian inflation indexes are treated as a group of risk indicators and limits are managed in the same way as for the other indicators. 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’s appetite for risk. In order to operate within the defined limits, ITAÚ UNIBANCO HOLDING hedges transactions with customers and proprietary positions, including its foreign investments. Derivatives are commonly used for these hedging activities, which can be either accounting or economic hedges, both governed by the institutional polices of ITAÚ UNIBANCO HOLDING. The 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; Itaú Unibanco Holding S.A. – Demonstrações Contábeis Completas em IFRS – 31 de Março de 2020 18/05/2020 10:14:42 F.110 1.4.4 Repossessed assets Assets received from the foreclosure of loans, including real estate, are initially recorded at the lower of: (i) the fair value of the asset less the estimated selling expenses, or (ii) the carrying amount of the loan.

• Losses in stress scenarios (Stress Testing): 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: metrics 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 market value (MtM – Marked 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: • ΔEVE: 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 interest rate shock; • ΔNII: 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 market value, allocated at the maturity dates; • Sensitivity (DV01- Delta Variation): impact on the market value of cash flows, when submitted to an one annual basis point increase in the current interest rates or index rate; • 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. ITAÚ UNIBANCO HOLDING uses proprietary systems to measure the consolidated market risk. The processing of these systems occurs in a high-availability access-controlled environment, which has data storage and recovery processes and an infrastructure that ensures business continuity in contingency (disaster recovery) situations. 2.1 VaR - Consolidated ITAÚ UNIBANCO HOLDING Is calculated by Historical Simulation, i.e. the expected distribution for profits and losses (P&L) of a portfolio over time can be estimated from past behavior of returns of market risk factors for this portfolio. VaR is calculated at a confidence level of 99%, historical period of 4 years (1000 business days) and a holding period of one day. In addition, in a conservative approach, VaR is calculated daily, with and without volatility weighting, and the final VaR is the more restrictive of the values given by the two methods. From 01/01 to 03/31/2020, the average total VaR in Historical Simulation was R$ 375 or 0.3% of total stockholders’ equity (R$ 334 from 01/01 to 12/31/2019 or 0.2% of total stockholders’ equity).

2.1.2 Currency risk The purpose of ITAÚ UNIBANCO HOLDING's management of foreign exchange exposure is to mitigate the effects arising from variation in foreign exchange rates, which may present high- volatility periods. The currency (or foreign exchange) risk arises from positions that are sensitive to oscillations in foreign exchange rates. These positions may be originated by financial instruments that are denominated in a currency other than the functional currency in which the balance sheet is measured or through positions in derivative instruments (for negotiation or hedge). Sensitivity to currency risk is disclosed in the table VaR Total (Historical Simulation) described in item 2.1 – VaR Consolidated – ITAÚ UNIBANCO HOLDING. 2.1.3 Share Price Risk The exposure to share price risk is disclosed in Note 5, related to Financial Assets Through Profit or Loss - Securities, and Note 8, related to Financial Assets at Fair Value Through Other Comprehensive Income - Securities. 3. 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 operates. All activities are subject to verification by independent validation, internal control and audit areas. Liquidity management policies and limits are based on prospective scenarios and senior management’s guidelines. These scenarios are reviewed on a periodic basis, by analyzing the need for cash due to atypical market conditions or strategic decisions by ITAÚ UNIBANCO HOLDING. ITAÚ UNIBANCO HOLDING manages and controls liquidity risk on a daily basis, using procedures approved in superior committees, including the adoption of liquidity minimum limits, sufficient to absorb possible cash losses in stress scenarios, measured with the use of internal and regulatory methods. Additionally the following items for monitoring and supporting decisions are periodically prepared and submitted to senior management: • Different scenarios projected for changes in liquidity; • Contingency plans for crisis situations; • Reports and charts that describe the risk positions; • Assessment of funding costs and alternative sources of funding; • Monitoring of changes in funding through a constant control of sources of funding, considering the type of investor, maturities and other factors. 3.1 Primary sources of funding ITAÚ UNIBANCO HOLDING has different sources of funding, of which a significant portion is from the retail segment. Of total customers’ funds, 37.3% or R$ 313.9 billion, are immediately available to customers. However, the historical behavior of the accumulated balance of the two largest items in this group – demand and savings deposits - is relatively consistent with the balances increasing over time and inflows exceeding outflows for monthly average amounts.

I - Composition of capital The Referential Equity (PR) used to monitor the compliance with the operating limits imposed by BACEN, is the sum of three items, namely: • Common Equity Tier I: the sum of capital, reserves and retained earnings, less deductions and prudential adjustments. • Additional Tier I Capital: consists of instruments of a perpetual nature, which meet eligibility requirements. Together with Common Equity Tier I it makes up Tier I. • Tier II Capital: consists of subordinated debt instruments with defined maturity dates that meet eligibility requirements. Together with the Common Equity Tier I and the Additional Tier I Capital, it makes up the Total Capital.

The result of the last ICAAP – which was dated December 2019 – indicated that ITAÚ UNIBANCO HOLDING has, in addition to capital to cover all material risks, a significant capital surplus, thus assuring the solidity of the institution’s equity position. In order to ensure that ITAÚ UNIBANCO HOLDING is sound and has the capital needed to support business growth, the institution maintains PR levels above the minimum level required to face risks, as demonstrated by the Common Equity, Tier I Capital and Basel ratios. The Basel Ratio reached 13.3% at March 31, 2020, 2.5 p.p. lower than at December 31, 2019, mainly due to the foreign exchange impact, the provision of interest on capital, dividends referring to fiscal year 2019, and increase in risk-weighted assets, partially diminished by net income in the quarter and issuance of level 1 and level 2 debts. Additionally, ITAÚ UNIBANCO HOLDING has a surplus over the required minimum Referential Equity of R$ 55,737, well above the ACP of R$ 36,523 and generously covered by available capital. 03/31/2020 12/31/2019 Amount Ratio Amount Ratio Required Current Required Current Required Current Required Current Common Equity Tier I 46,958 107,668 4.5% 10.3% 40,108 117,328 4.5% 13.2% Additional Tier I Capital - 17,312 - - - 11,368 - - Tier I (Common Equity Tier I + Additional Tier I Capital) 62,611 124,980 6.0% 12.0% 53,478 128,696 6.0% 14.4% Tier II - 14,238 - - - 11,900 - - Referential Equity (Tier I + Tier II) 83,481 139,218 8.0% 13.3% 71,304 140,596 8.0% 15.8% Amount Required for Additional Capital Buffers (ACP) 36,523 3.5% 31,195 3.5% The fixed assets ratio shows the commitment percentage of adjusted Referential Equity with adjusted permanent assets.

VI - Stress testing The stress test is a process of simulation of extreme economic and market conditions in the institution’s results and capital. The institution has conducted this test since 2010 with a view to assessing its solvency in plausible scenarios of a systemic crisis, and identifying areas that are more susceptible to the impact of stress and can be subject to risk mitigation. To perform the test, macroeconomic variables for each stress scenario are estimated by the economic research department. The scenarios are defined according to their importance to the bank’s results, and the probability of occurrence, and they are submitted to the approval of the Board of Directors on an annual basis. Projections of macroeconomic variables (e.g. GDP, benchmark interest rate and inflation) and of the credit market (such as fundraising, loans, default rate, spread and fees) for these scenarios are based on external shocks or by using models validated by an independent area. These projections affect the budgeted result and balance sheet, which in turn influence the risk-weighted assets and capital and liquidity ratios. The stress test is also an integral part of ICAAP, with the main purpose of assessing whether, even in severe adverse conditions, the institution would have appropriate capital levels and its business would be unaffected. This information allows potential risk factors to be identified in business, supporting the Board of Directors’ strategic decisions, the budgetary process and discussions on credit granting policies, in addition to being used as input for risk appetite metrics. VII – 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, since October 2015 ITAÚ UNIBANCO HOLDING has sent the Leverage Ratio to BACEN, in accordance with Basel recommendations, on the basis of the ratio’s behavior for the period between 2011, when it was introduced, and 2017. d) Management Risks of insurance and private pension I – Management Structure, roles and responsibilities In line with good domestic and international practices, ITAÚ UNIBANCO HOLDING has a risk management structure that ensures that the risks arising from insurance and pension plans products are properly monitored and reported to the appropriate bodies. The management process of insurance and pension plans risks is independent and focuses on the specific nature of each risk. ITAÚ UNIBANCO HOLDING has committees to define the management of funds from the technical reserves for insurance and private pensions, to issue guidelines for managing these funds with the objective of achieving long term returns, and to define valuation models, risk limits and strategies on allocation of funds to specific financial assets. The members of these committees are not only executives and those directly responsible for the business management process, but also heads and coordinators of commercial and financial areas.

II – Risks of Insurance and Private Pensions ITAÚ UNIBANCO HOLDING offers its products to customers through a bancassurance structure or direct distribution. Life, personal accident, loan and multiple peril insurance products are mainly distributed by a bancassurance operation. Life insurance and pension plans are, in general, medium or long-term products and the main risks involved in the business may be classified as demographic, financial and behavioral. • Demographic risk relates to: i) a greater than expected increase in life expectancies for products with survivorship coverage (mostly pension plans); and ii) a greater than expected decrease in mortality rates for products with life coverage (mostly life insurance). • Financial risk: is inherent in the underwriting risk of products that offer a contractual financial guarantee, this risk being considered insurance risk • Behavioral risk relates to a greater than expected increase in the rates of conversion into annuity income, resulting in increased payments of retirement benefits. Estimated actuarial assumptions are based on the past experience of ITAÚ UNIBANCO HOLDING, on market benchmarks and on the experience of the actuaries. a) Effect of changes on actuarial assumptions To measure the effects of changes in the key actuarial assumptions, sensitivity tests were conducted in the amounts of current estimates of future liability cash flows. The sensitivity analysis considers a vision of the impacts caused by changes in assumptions, which could affect the income for the period and stockholders’ equity at the balance sheet date. This type of analysis is usually conducted under the ceteris paribus condition, in which the sensitivity of a system is measured when one variable of interest is changed and all the others remain unchanged. The results obtained are shown in the table below: (1) Impact in Results and Stockholders’ Equity (2) 12/31/2019 Sensitivity Test 03/31/2020 Private Pension Insurance Private Pension Insurance Mortality Rates 5% increase 25 - 25 - 5% decrease (37) ( 1) (37) ( 1) Risk-free Interest Rates 0.1% increase 61 12 61 12 0.1% decrease (63) ( 12) ( 63) ( 12) Conversion in Income Rates 5% increase 20 - 20 - 5% decrease (21) - ( 21) - Claims 5% increase - ( 47) - ( 47) 5% decrease - 47 - 47 (1) Amounts net of tax effects.

Life, personal accident, loan and multiple peril insurance products are mainly distributed by a bancassurance operation. Life insurance and pension plans are, in general, medium or long-term products and the main risks involved in the business may be classified as demographic, financial and behavioral. • Demographic risk relates to: i) a greater than expected increase in life expectancies for products with survivorship coverage (mostly pension plans); and ii) a greater than expected decrease in mortality rates for products with life coverage (mostly life insurance). • Financial risk: is inherent in the underwriting risk of products that offer a contractual financial guarantee, this risk being considered insurance risk • Behavioral risk relates to a greater than expected increase in the rates of conversion into annuity income, resulting in increased payments of retirement benefits.

b) Liquidity Risk Liquidity risk is identified by ITAÚ UNIBANCO HOLDING as the risk of lack of liquid resources available to cover its current obligations at a given moment. For insurance operations, the liquidity risk is managed continuously by monitoring payment flows against liabilities, compared to the inflows generated by its operations and financial assets portfolio. Financial assets are managed in order to optimize the risk-return ratio of investments, considering, on a careful basis, the characteristics of their liabilities. The risk integrated control considers the concentration limits by issuer and credit risk, sensitivities and market risk limits and control over asset liquidity risk. Thus, investments are concentrated in government and private securities with good credit quality in active and liquid markets, keeping a considerable amount invested in short-term assets, available on demand, to cover regular needs and any liquidity contingencies. Additionally, ITAÚ UNIBANCO HOLDING constantly monitors the solvency conditions of its insurance operations. 03/31/2020 12/31/2019 Liabilities Assets Liabilities Liabilities Assets Liabilities Liabilities Assets (1) (2) (2) (1) (2) (2) amounts DU DU amounts DU DU Insurance operations Backing asset Unearned premiums LFT, repurchase agreements, NTN-B, CDB, LF and debentures 2,303 59.0 22.9 2,343 59.1 22.9 IBNR, PDR e PSL LFT, repurchase agreements, NTN-B, CDB, LF and debentures 844 52.1 30.1 876 49.9 29.0 Redemptions and Other Unsettled Amounts LFT, repurchase agreements, NTN-B, CDB, LF and debentures 13 7.9 22.9 13 7.9 22.9 Mathematical reserve for benefits to be granted and benefits granted LFT, repurchase agreements, NTN-B, NTN-C, debentures 17 188.5 28.7 204 16.9 2.6 222.4 22.9 222.4 22.9 Financial surplus LFT, repurchase agreements, NTN-B, NTN-C, CDB, LF and debentures 2 2 Other provisions LFT, repurchase agreements, NTN-B, CDB, LF and debentures 250 7.1 104.5 250 6.9 104.5 Subtotal Subtotal 3,429 3,688 Pension plan, VGBL and individual life operations Related expenses LFT, repurchase agreements, NTN-B, CDB, LF and debentures 89 126.2 82.6 89 126.2 82.6 Unearned premiums LFT, repurchase agreements, NTN-B, CDB and debentures 12 11.1 20.8 13 11.1 20.8 Unsettled claims LFT, repurchase agreements, NTN-B, CDB and debentures 49 11.1 20.8 47 11.1 20.8 22 11.1 20.8 22 11.1 20.8 IBNR LFT, repurchase agreements, NTN-B, CDB and debentures Redemptions and Other Unsettled Amounts LFT, repurchase agreements, NTN-B, CDB and debentures 288 11.1 20.8 318 11.1 20.8 Mathematical reserve for benefits granted LFT, repurchase agreements, LTN, NTN-B, NTN-C, NTN-F, CDB, LF and debentures 2,885 126.2 82.7 2,781 126.2 82.8 Mathematical reserve for benefits to be granted – PGBL/ VGBL LFT, repurchase agreements, LTN, NTN-B, NTN-C, NTN-F, CDB, LF and (3) debentures 198,376 180.6 57.0 204,394 180.6 57.0 LFT, repurchase agreements, NTN-B, NTN-C, debentures 5,198 199.8 110.1 5,099 199.8 110.1 Mathematical reserve for benefits to be granted – traditional Other provisions LFT, repurchase agreements, NTN-B, NTN-C, CDB, LF and debentures 1,273 199.7 110.1 1,273 199.7 110.1 610 199.8 110.1 610 199.8 110.1 Financial surplus LFT, repurchase agreements, NTN-B, NTN-C, CDB, LF and debentures Subtotal Subtotal 208,802 214,646 Total technical reserves Total backing assets 212,231 218,334 (1) Gross amounts of Credit Rights, Escrow Deposits and Reinsurance.

ITAÚ UNIBANCO HOLDING is monitoring the economic effects of this pandemic in Brazil and the other countries where it operates, which may adversely affect its results. At the beginning of the COVID-19 outbreak, the Institutional Crisis Management Committee was set up, which monitors, on a daily basis, the effects of the spread of the pandemic and its impacts on our operations, in addition to the government actions to mitigate the effects of this pandemic. The Brazilian Government, by means of the National Monetary Council and the Central Bank of Brazil, has been adopting measures to mitigate the impacts caused by COVID-19, particularly on loan transactions, funding operations, reduction of reserve requirements and capital-related issues. Accordingly, by the date of this disclosure, ITÁÚ UNIBANCO HOLDING has identified: (a) an increase in loan and financing operations, particularly to companies; (b) increases in requests for renegotiations and extensions for loan operations; (c) impacts on the allowance for doubtful accounts and impairment of financial assets; (d) impacts on the pricing of its financial instruments arising from the high volatility in the markets and (e) an increase in funding operations. It is worth noting that ITAÚ UNIBANCO HOLDING maintains its operational activities, even with the measures adopted to contain COVID-19, and continues to monitor and assess the identified impacts of this pandemic on its results, as well as its effects on critical estimates and judgments for the preparation of its Consolidated Financial Statements. The effects of COVID-19 on the Financial Statements are reflected in the notes: 5 – Financial assets at fair value through profit or loss and designated at fair value through profit or loss – Securities, 6 – Derivatives, 8 – Financial Assets at Fair Value Through Other Comprehensive Income – Securities, 10 - Loan and lease operations portfólio and Note 28 – Fair value of financial instruments.
