Management Discussion & Analysis Executive Summary Managerial Income Statement In this report, besides making adjustments for extraordinary items, we have applied managerial criteria to present our income statement. In the accounting statements, these criteria affect the breakdown of our income statement, but not the amount of net income. The main adjustments made in the managerial figures include the tax effects of the hedges on investments abroad, which were originally included in tax expenses (PIS and COFINS), and the income tax and social contribution on net income, which have been reclassified to financial margin. The appreciation of the Brazilian Real against the currencies of the countries in which the Company has investments meant that the impact of the overhedging strategy on these investments was material during this quarter. These reclassifications enable us to perform business analyses from the management point of view, and a reconciliation of the management and accounting figures is shown in the table below.

Recurring managerial return on equity was 18.9%. The Company continues to make significant headway on the digital front. In the second quarter, recurring managerial result 58% of product purchases by individuals were made digitally, which represents a 35% increase of purchases in these channels from the first quarter of 2021. Along with this significant R$6.5 bn +2.3% increase, user’s satisfaction with digital channels measured based on the NPS (net promoter 2Q21 2Q21 x 1Q21 score) for the Super App (the bank’s mobile channel for individual customers) remains very high, at 78 points. As in the previous quarter, the loan portfolio continued to grow, up 4.6% in Brazil and up 0.3% on a consolidated basis. Excluding the effects of exchange rate variations, the credit portfolio consolidated portfolio grew by 5.0%. Mortgage loans grew by 12.8% in this quarter, keeping on the record production initially observed in the first quarter. Customer satisfaction has already R$909.1 bn +0.3% shown signs of improvement, having been impacted by a strong increase in demand, with a 7 point increase in the NPS for the operation. Also noteworthy are the increases in the credit card, 2Q21 2Q21 x 1Q21 vehicles and payroll loan portfolios, which were up 6.7%, 5.7% and 5.5%, respectively. In addition we had a higher average balance in personal credit and in overdraft portfolios. The increase in the volume of credit, the increasing representation of overdraft and personal credit and the financial margin with clients higher number of calendar days more than offset narrower spreads and made a positive contribution to our higher financial margin with clients, up 3.9%, in the quarter to R$16.8 billion. R$16.8 bn +3.9% The cost of credit increased to R$4.7 billion, due to higher expenses in the wholesale business in 2Q21 2Q21 x 1Q21 Brazil. It is worth mentioning that delinquency rates in the retail segment in Brazil remains historically low. Margin with the market was down in the quarter to R$2.0 billion, with the financial margin with the market treasury in Brazil at a very high level of performance and with lower gains in the units in Latin America. Commissions and fees were up due to the impact of (i) higher economic activity in revenue from cards (both issuer and acquirer), (ii) higher levels of capital markets activity and R$2.0 bn -19.1% resulting higher gains from economic and financial advisory services, and (iii) higher revenue 2Q21 2Q21 x 1Q21 from performance fees in asset management. Non-interest expenses increased in the quarter, driven by higher personnel expenses, which were seasonally lower in the first quarter, compensated by a decrease in administrative expenses. cost of credit Regarding the minority interest in XP Inc, at the end of 2020 we announced the partial spin-off of the investment held in XP Inc to a new company (XPart S.A.). On May 31, 2021, XPart was R$4.7 bn +14.1% constituted using the portion of the investment in XP Inc. After these events, Itaú Unibanco no 2Q21 2Q21 x 1Q21 longer holds an equity interest in XP Inc. and does not have any interest in XPart SA. This operation impacted on the statements of Itaú Unibanco with a reduction in permanent assets, a reduction in Shareholders’ Equity and the equity pickup result was earned until May 31, 2021, with an impact on fees in the managerial result. The effect was neutral in terms of capital. fees and insurance In the first half of 2021, recurring managerial result was up 59.4% from the same period of the previous year. Despite the positive effect of the loan portfolio increase of 12.0%, financial R$11.3 bn +2.7% margin with clients was down 1.6%. This reduction was driven by the change in the mix of credit products, with the reduced use of revolving credit and greater use of secured credit products, 2Q21 2Q21 x 1Q21 lower spread on credit products, and the impact of lower interest rates on working capital and liability margin. However, the reduction in financial margin with clients was more than offset by higher financial margin with the market and the lower cost of credit. Both moves were driven by non-interest expenses the unexpectedly volatile macroeconomic scenario in the first quarter of 2020. Another highlight was the 0.8% increase in non-interest expenses in Brazil, despite the 8.3% inflation rate in the period. It is worth mentioning that we continue investing in technology and our R$12.6 bn +0.9% business, and our efficiency program has significantly helped improve this performance 2Q21 2Q21 x 1Q21 significantly. The 3.5% increase in expenses in the consolidated is driven by foreign exchange variations on Latin American operations. 18.5% 18.9% Recurring Managerial 15.7% 16.1% Return on Average 13.5% 5,388 6,398 6,543 5,030 Equity 4,205 18.9% 2Q20 3Q20 4Q20 1Q21 2Q21 Recurring Managerial Result Annualized Recurring Managerial Return on Average Equity (quarterly) Itaú Unibanco Holding S.A. 08

Management Discussion & Analysis Income Statement Analysis Managerial Financial Margin Highlights • Financial margin with clients grew by 3.9% in the quarter due to the higher average volume of credit, greater representation of revolving credit portfolios and the higher number of calendar days in the quarter. These positive effects were partially offset by the reduction in the credit spread for individuals, especially mortgages and vehicles. • The 19.1% reduction in the financial margin with the market in the quarter was due to lower gains in the units in Latin America.

Management Discussion & Analysis Income Statement Analysis Non-interest Expenses Highlights • Non-interest expenses increased by 0.9% compared to the previous quarter, driven by higher personnel expenses, which are seasonally lower in the first quarter. This increase was partially offset by lower administrative expenses, mainly marketing and third party service expenses. • Strategic cost management led to a 0.8% increase in expenses in Brazil from the first half of 2020, despite the 8.3% inflation rate (IPCA) in the period. The growth in expenses in Latin America, driven by the foreign exchange variation, resulted in a 3.5% increase in total non-interest expenses.

Management Discussion & Analysis Balance Sheet Balance Sheet Highlights • Total assets were down 2.8% in the quarter and down 0.5% in the last 12 months, mainly due to exchange variations and reduced liquidity. The 28.5% decrease in permanent assets was driven by the effects of the partial spin-off of the investment held in XP Inc. into a new company, XPart. XPart was incorporated on May 31, 2021, and as a result Itaú Unibanco no longer has equity interest in XP Inc. or an equity interest in XPart. • Deposits decreased by 3.4% in the quarter, driven by the foreign exchange variations in our Latin American operations, and increased by 9.1% in the last 12 months, mainly due to increases in demand deposits (14.8% p.a.), savings deposits (12.5% p.a.), and time deposits (6.8% p.a.).

Highlights • The 10.2% increase in the recurring managerial result in the quarter was boosted by higher financial margin, driven by higher credit volume, and higher commissions and fees, mainly due to higher revenue from card issuing activities. Additionally, higher personnel expenses are driven by typical first-quarter seasonality. • The recurring managerial result was up 37.2% year-on-year. Financial margin decreased, driven by the change in the loan portfolio mix with lower use of revolving credit and the higher use of secured credit products. Commissions and fees increased.

(c) Under IFRS, the effect of accounting at fair value of the acquisition of interest in Porto Seguro Itaú Unibanco Participações S.A. was recognized. (d) Criterion for write-off of financial assets on IFRS considers the recovery expectative. (e) Under IFRS (IAS 17) the financial lease operations are recorded as Fixed Assets, as a contra-entry of Other Financial Liabilities. Under BRGAAP, as from September 30 th, 2015, the consideration of these transactions are now recorded in result, in accordance with CMN Resolution No. 3,617/08.

Dear reader We find ourselves at a moment in the market when the rise of new technologies, the use of data and the arrival of new participants on the financial industry scene represent a huge competitive challenge. Thus, the strategy for us to stand out in this scenario has been guided by serving the customer how, when and where it is most convenient for them. We can see how we have effectively achieved this objective in all areas where we operate – we have the largest range of services in the market – based on an effective combination of continuous investment in new technology solutions, and a cultural transformation that enables us to be a simpler, more agile and more efficient bank where people enjoy autonomy and play a leading role. So, we have launched the #Feito com Você (WeDidItWithYou) campaign that leads us to admit that who knows what the customer wants is the customer himself, and we have done this successfully by actively listening to their needs. In this respect, we allocated priority in this quarter to an ambitious project Clients for a strategic review of our Retail operations: iVarejo 2030, which involves a complete makeover of the customers’ experience by allocating a new meaning to the value proposal of our businesses on two main fronts, but not just confined to them: The Phygital and Omnichannel approach, which we are introducing into our business model, and the e-Commerce model by which the Digital Channels will receive a strong boost as we multiply our Digital Sales capability. phygital The Phygital approach encapsulates our belief that there is huge potential to be explored in the fact that the physical and digital worlds are mutually complementary. Basically, we are on the path to offering a totally digital bank, with the convenience of a branch network service. In other words, the best of both worlds, and the customer gets to choose. At the same time, the Omnichannel strategy allows us to integrate the channels, creating new points of contact with the customers and engaging in conversation by drawing on the information from previous contacts on any of our channels. Conversation using this type of approach has increased three- or fourfold and generates an incomparably higher level of satisfaction than Clients the more traditional approaches. Another good example created by this connection between customer services is that it allows our clients to ask for support from a manager or specialist online while they are perusing on our digital channels. This is what we call “click-to-human”. This is how we have doubled or tripled our sales conversion, and we expect to continue to evolve over time, especially in products that demand greater specialization, omnichannel such as insurance, investments, purchasing pools and real estate credit. In the first six months of 2021, the volume of business from an O2O (online-to-offline) connection exceeded R$ 9.0 billion in deals1, strengthening the potential of the Phygital and Omnichannel strategy. (1) Considers: Individual credit (credit, payroll-deductible); Individual investments (treasury, savings, funds, pension); PF Renegotiation; Individual Credit Cards; portability of Individual credit and Endorsement. 41

At the same time, the e-Commerce Program is an initiative with the capacity to transform our application into a powerful relationship and e-commerce platform. Cell phones have increasingly become people’s preferred channel, and therefore our priority, too. In recent years, we have bolstered investments in our app to convert it to a one-stop-shop, offering a complete range of products and services. Government Solutions for the Aut inv Vehicle Finance Renegotiation Itaú super app Services Hub Forex MCP PIX Investments Programs present time Based on a culture of testing and learning in solutions dedicated to the best user experience, with an end-to-end approach, we are now reaping the fruits of a journey of developing co-creation with the customer. App Itaú: 78 NPS points An all-time level! To intensify our digital sales, we have created the Live Program whose aim is to transform how we offer digital products and services based on a new operating model with new functionalities in data analysis, technology solutions in digital marketing, while adding an e-commerce mentality to the operation. Our ambition is to quadruple the volume of sales on the digital channels. Implementation of the 2030 iVarejo (iRetail) Program • 75% implemented in 2021 • 100% implemented in 2022 Ambitions To account for 50% of the bank’s revenue. Training hundreds of people using management methodology and tools. 42

We have also launched the new campaign “O Itaú tem um cartão que dá match com você” (Itaú has a card that matches you), aimed at showcasing our complete portfolio and designed to meet each customer’s needs and strengthen our position in the segment. The 1 in 3 cards most sought-after in Brazil is Itaú card in Brazil Some of our differentials: Pay how you like: contactless, WhatsApp Pay, PayPal, online debit. All contactless digital payment portfolios: Apple Pay, Samsung Pay e Google Pay. An iPhone forever, have a new iPhone whenever you want. Count on us. Itaucard, market leader in credit cards and financial solutions in Brazil, received in June the RA1000 Seal of Excellence awarded by Reclame AQUI (a consumer protection site). The seal acknowledges businesses that stand out for their excellent service levels on the site, like high solution rate, response and reputation. This is the result of a lot of work and the tireless quest to channel our efforts to creating strategies and solutions that help improve our customers’ satisfaction. Find out more at: https://www.reclameaqui.com.br/empresa/itaucard/ Did you detect a purchase you do not recognize? Report the problem on the Itaú app. Now, whenever customers do not recognize a purchase made with their credit card, they can challenge it using the Itaú app without having to call the Hot desk. 43

We have zeroed the annual fee on Black and Infinite cards for investors. We have extended the benefit of zero annual fees to the Itaú Personnalité Black and Itaú Personnalité Infinite cards. Customers with investments from R$ 50,000 upwards in the segment are now exempted from annual fees on both cards. We have extended the account opening service on the digital channels to over 4 million small businesses. Besides offering this service to MEI (Very Small Entrepreneur) account holders, we are expanding the customer base of businesses that can open an account online and directly through the site. Beginning in May, customers with annual invoicing of up to R$ 800,000 can now open an account via the site, which means 4 million companies managing their finances on our digital channels. We have launched a tool that enables customers to monitor card receivables from other banks. Using this new development, we will expand the offer of credit guaranteed by receivables. The functionality, called Card Financial Manager, enables customers to view their balance of receivables pledged as collateral in multiple financial institutions. It is being launched precisely when the regulatory changes stipulated by the Central Bank in this respect are coming into effect. Rede is announcing an additional offer of R$ 2.3 billion for discounting receivables and is launching a platform that consolidates sales made through all credit card companies. The company simultaneously launched an online platform so that retailers can view the schedule of receivables in a single environment, irrespective of the brand, banks and machines involved in the transactions. We have incorporated into íon the investment aggregator functions, anticipating the debut of the second phase of open banking. The advent of this resource allows platform users to view all their investments, whether these are with Itaú or with other banks and brokerage houses. The customer can decide how they want to see this information: view the consolidated investment statement or broken down by product or institution. We have announced the launch of Quantamental for our Multimesas (Multiple Trading Desks) management model, a platform that allows managers to operate a portfolio taking advantage of our ability to attract resources and receiving remuneration as if they were the owners of an asset management company. The Quantamental team stands apart for the algorithm-based quantitative operating model and for the intensive use of robots that analyze various indicators in the search for patterns for evaluations and negotiations. The work has begun with two funds that were already in operation—the Quantamental Hedge and Quantamental Gems, which aim to exceed the CDI rate and the Small Cap Bovespa Index, respectively. 44

Through a multimarket fund, professional investors will have an opportunity to share in the financial growth of fledgling asset managers, such as the Rising Stars Program, for encouraging new asset managers. This initiative, unprecedented in Brazil, combines both the financial means for the development of independent asset managers, and the opportunity for customers to invest and share in those companies’ results. To do so, a multimarket investment fund will be structured in which customers will invest in promising asset managers with high growth potential. The proceeds will be channeled both to seed capital (a financing model designed for business projects in the early stages or not yet initiated), and to working capital for those companies. The fund will be available for placement with professional investors – those with financial assets of R$ 10 million and upwards. Our investment search and comparison tool, “Investir Em Que?”, has exceeded the 1 million accesses mark. The platform, which is open to the bank’s customers and to non-customers, offers a series of functionalities for those looking to invest: projected returns of the funds 12 months hence, a guidebook and comparison of market-wide funds with different classifications (fixed income, shares, exchange rate and multimarket), profitability graphs, risk ratings, search mechanisms (by amount, name or corporate tax number (CNPJ)), in addition to content that helps investors make their decisions. Access: https://investiremque.com.br/. We have launched an international ETF (Exchange Traded Fund, or “index fund”) in Healthcare Technology. This provides Brazilian investors with yet another possibility for sophisticated placement. The HTEK11 is the 15th ETF of Itaú Asset Management and will track the Morningstar US Exponential Technologies Healthcare Index consisting of the shares of 50 technology companies positioned to benefit from the topics of Medicine & Neuroscience and Bioinformatics. Technological innovations are transforming the healthcare sector, and not only do they have the potential to improve quality of life, but they are also an investment opportunity. At present, this index consists of companies like Eli Lilly, Johnson & Johnson, and Bristol-Myers Squibb, among others. We continued to push ahead with our business agenda around ESG criteria, strengthening our role in response to significant demands from society. We raised US$ 400 million from the United States International Development Finance Corporation (DFC) on the international market , which we intend to use to expand credit to small and middle market companies, focusing on economically vulnerable regions like the North and Northeast of Brazil, and companies where women are the controlling shareholders or run the business. We have also taken on a commitment to contribute R$ 400 billion by 2025, through business initiatives that promote an economy that is sustainable and increasingly green and inclusive. This figure encompasses three major operating fronts: loans to sectors that have a positive impact on society; structuring ESG transactions with clients, such as ESG bonds, ESG loans and green debentures; and ESG products for the retail sector, such as financing electric/hybrid cars, solar panels and micro credit. In July, we notified the market about the launch of the carbon offset platform to leverage transparency in the Voluntary Carbon Market, in partnership with the international banks CIBC (Canadian Imperial Bank of Commerce), NAB (National Australia Bank) and Nat West. (1) The DFC partnership with Itaú Unibanco exemplifies the DFC’s focus on regions of the world where women face the greatest challenges, and where this investment can have the greatest positive effect, primarily bearing in mind the consequences currently experienced due to the Covid-19 pandemic. This investment represents an advance in the initiative of the DFC, which has already raised over US$ 7 billion in private sector investment in projects for the economic inclusion of women entrepreneurs in developing countries. 45

Aligned with the Taskforce on Scaling Voluntary Carbon Markets – TSVCM, the project helps remove some currently existing barriers to the purchase of voluntary carbon offsets. The Carbon Project will be initially launched as a pilot project in August, to demonstrate the platform’s operational, legal and technical capabilities. Its objectives are: • Greater delivery of high-quality, carbon offset projects; • A marketplace for trading carbon, with transparency as regards prices and greater market liquidity; • The creation of an ecosystem backed by the offsets market; • The development of tools to help clients manage climate risk. With initiatives like those described above, it is our intention to strengthen our role as one of the main agents of economic and social transformation in Brazil. The Empresário Verde (Green Businessman) Plan is a product launched by Itaú BBA for the sustainable construction market. Itaú BBA has stipulated environmental targets in its traditional credit line intended for companies in the civil construction industry, launching the Green Businessman Plan. To obtain differentiated financing conditions, commercial or residential real estate developments need to achieve savings of at least 20% in water, energy and the energy incorporated into materials. Given the deterioration of the COVID-19 pandemic in Brazil, we joined with other companies in donating 3.4 million items of intubation medication. In an emergency response, we put together a group of companies to donate 3.4 million items of intubation medication to the Ministry of Health, a sufficient amount to manage 500 beds for a period of one-and-a-half months. The items, imported from China, are certified by Anvisa, as well as by the Chinese agency, and will be donated in full to the Brazilian government which will also oversee the distribution by the states through the SUS-Single Health System. Itaú Unibanco Holding and XPart’s segregation The legal and accounting segregation of Itaú Unibanco Holding and XPart approved by the Extraordinary Shareholders Meeting as of January 31, 2021 was carried out on May 31, 2021, since on this date the Federal Reserve Board (FED) approval became effective. On July 27, 2021, after the receipt of the approval of the operation by the Central Bank of Brazil, XPart S.A. (“XPart”) had its articles of association registered with the JUCESP (São Paulo state’s Board of Trade). On May 28, 2021, XP Inc. (“XP”) expressed its interest in merging XPart and, accordingly, XP and Itaúsa announced to the market that they have reached a final understanding regarding the merger of XPart into XP, to be deliberated by the General Stockholders’ Meetings of these companies on a date to be defined. As previously disclosed, should the said merger be approved by the stockholders of XP and XPart, Itaú Unibanco Holding’s stockholders, who are XPart’s stockholders and until the cut-off date¹ will be entitled to receive securities issued by XPart, will receive: (a) as for Itaú Unibanco Holding’s controlling stockholders (Itaúsa e IUPAR) and the holders of American Depositary Receipts (ADRs), Class A shares issued by XP.(b) as for Itaú Unibanco Holding’s remaining stockholders, Level I sponsored Brazilian Depositary Receipts (BDRs) backed into XP Class A shares. In case XPart is not merged or is not listed on a stock exchange within a period of 120 days as from the date of approval from the Central Bank of Brazil above mentioned, stockholders will be entitled to withdraw from XPart. Our stockholders and the market informed of the progress and developments of this operation. 46 (1) It is planned that the cut-off date will occur after the close of trading on the day of the XP and XPart’s General Meetings.

Results Analysis The percentages of increase or decrease in this section refer to the comparison between the accumulated figure for the year 2021 in relation to the same period of 2020, unless otherwise indicated. In the first half of 2021, our recurring managerial income stood at R$12.9 billion, an increase of 59.4% over the same period of the previous year. The recurring Return on Shareholders’ Equity was 18.8%. The highlight was growth de 12.0% in the total credit portfolio. We give below the growth of the portfolios in the main segments: • 22.2% for private individuals; • 23.4% in very small, small and middle market companies in Brazil; • 10.6% in large companies in Brazil; • reduction of 2.7% iin the Latin America portfolio, which remained practically stable after stripping out the impact of the exchange rate variance; In comparison with the first half of 2020, we saw growth of 8,4% in credit origination in Brazil, namely: • 43.7% for private individuals; • 2.8% for small, medium-sized companies; • a reduction of 5.4% for large companies. In spite of the positive effect of the growth of the portfolio, there was a reduction of 1.6% in the net interest margin with clients. This reduction is due to the change in the mix of the credit portfolio, whether due to the smaller share of revolving products, or the larger share of collateralized products, as well as lower spreads on credit products and the impact of the lower interest rate on our own working capital and on the liabilities margin. Nevertheless, this reduction in the net interest margin with clients was more than compensated by the higher net interest margin with the market and the reduction in the cost of credit. Both movements reflect the high volatility in the market during the 1st quarter of 2020. Revenues from services fees and insurance rose by 6.6% for the year. This increase was the result of higher billings in credit card issuance, higher revenues from credit transactions and financial guarantees provided, as well as higher earnings from economic and financial advisory due to greater capital market activity. Non-interest expenses rose by 0.8% in Brazil, even with accumulated inflation of 8.3% in the period. It is worth pointing out that we continue to invest in technology and in our business, and our efficiency program has made a decisive contribution to this performance. The 3.5% increase in expenses in the consolidated figures refers to exchange rate variance in the operations in Latin America. 48

The proposal establishes a payment in cash of R$ 2.4 billion for payroll management. This payment will be recorded as “Intangible” and recognized in the statement of income on a deferred basis.This operation reaches 618 thousand public servants, 20% of which concentrated in the metropolitan region of Belo Horizonte; a balance of payroll loans portfolio of R$ 7.7 billion and; 6.3 thousand companies that are suppliers of the State.

Independent Auditor – CVM Instruction No. 381 Procedures Adopted by the Company Our operating policy, including subsidiaries, when contracting non-external audit-related services from our independent auditors, is based on applicable regulations and internationally accepted principles that protect the independence of the auditors. These principles state that: (a) the auditors must not audit their own work, (b) the auditors must not hold managerial positions at their clients, and (c) the auditors must not promote their clients’ interests.

Note 2 – Presentation of the Consolidated Financial Statements a) Presentation The financial statements of ITAÚ UNIBANCO HOLDING and its subsidiaries (ITAÚ UNIBANCO HOLDING CONSOLIDATED) have been prepared in accordance with the Brazilian Corporate Law, as amended by Laws 11,638, of December 28, 2007, and 11,941, of May 27, 2009, and with instructions issued by the National Monetary Council (CMN), the Central Bank of Brazil (BACEN), the Brazilian Securities Commission (CVM), the National Council of Private Insurance (CNSP), the Superintendence of Private Insurance (SUSEP) and the National Superintendence of Supplementary Pensions (PREVIC), which include the use of accounting estimates for setting up provisions and valuing financial assets. The information contained in the financial statements and accompanying notes is consistent with the management accounts. The information in the financial statements and accompanying notes evidence all relevant information inherent in the financial statements, and only them, which are consistent with information used by management in its administration. With the entry into force of the BCB Resolution nº 2/2020, as from January 2021, the Balance Sheet accounts are presented in order of liquidity and enforceability. The presentation of the Statements of Value Added is required by the Brazilian corporate legislation and by the accounting practices adopted in Brazil applicable to publicly-held companies. This Statement was prepared in accordance with the criteria established by Technical Pronouncement CPC 09 – Statement of Value Added. Leases are shown at present value in the Consolidated Balance Sheet. The related income and expenses, representing the financial results of these operations, are grouped together under Loan, Lease and Other Credit Operations in the Consolidated Statement of Income. Advances on exchange contracts have been reclassified from Other Liabilities – Foreign Exchange Portfolio to Loan Operations. Foreign exchange income consists of exchange rate differences on balance sheet accounts denominated in foreign currencies. b) Consolidation The consolidated financial statements of ITAÚ UNIBANCO HOLDING relate to transactions carried out by its branches and subsidiaries in Brazil and abroad and investment funds which it controls. In ITAÚ UNIBANCO HOLDING, goodwill recorded in subsidiaries is amortized on the basis of anticipated future profitability and appraisal reports, or upon realization of the investment, according to the rules and guidance of CMN and BACEN. The difference in Net Income and Shareholders’ Equity between ITAÚ UNIBANCO HOLDING and ITAÚ UNIBANCO HOLDING CONSOLIDATED (Note 15d) results substantially from the adoption of different criteria for the amortization of goodwill originating from acquisitions of investments, for recognizing transactions with minority shareholders where there is no change in control (Note 3I) and for recognizing exchange differences, prior to January 1, 2017, on foreign investments and hedging these investments, which are denominated in currencies other than the functional currency of the parent company, net of the corresponding tax effects. The effects of foreign exchange differences on foreign investments are classified under the heading Income on Securities and Derivatives Financial Instruments in the Consolidated Statement of Income for subsidiaries with the same functional currency as the parent company, and in Other Comprehensive Income for subsidiaries with a different functional currency.

c) Critical accounting estimates and judgments The preparation of Consolidated and Individual Financial Statements requires Management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and contingent assets and liabilities at the date of the Financial Statements, due to uncertainties and the high level of subjectivity involved in the recognition and measurement of certain items. Estimates and judgments considered more relevant by ITAÚ UNIBANCO HOLDING CONSOLIDATED are related to the following topics: Topic Notes Consolidation 2c (I) and 2b Fair value of financial instruments 2c (II) and 17 Provision for loan losses 2c (III) and 6 Goodwill impairment 2c (IV) and 14 Deferred income tax and social contribution 2c (V) and 11 Defined benefit pension plans 2c (VI) and 19 Contingent assets and liabilities, legal obligations and tax and social security obligations 2c (VII) and 9 Technical provisions for insurance, pension plan and premium bonds 2c (VIII) and 8 I. Consolidation—subsidiaries are all those in which ITAÚ UNIBANCO HOLDING CONSOLIDATED’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. The consolidated financial statements are prepared using consistent accounting policies. Intercompany asset and liability account balances, income accounts and transaction values have been eliminated. II. Fair value of financial instruments—the fair value of financial instruments, including derivatives that are not traded in active markets, is calculated by using valuation techniques based on assumptions that consider market information and conditions. The main assumptions are: historical data, information on similar transactions and pricing techniques. For more complex or illiquid instruments, significant judgment is necessary to determine the model used with the selection of specific inputs and, in certain cases, evaluation adjustments are applied to the model amount our price quoted for financial instruments that are not actively traded. The methodologies used to estimate the fair value of certain financial instruments are described in Note 17. III. Provision for loan losses - The analysis of the provision for loan losses from the operations granted by ITAÚ UNIBANCO HOLDING CONSOLIDATED is conducted based on the assessment of the default classification (Ratings AA-H), on an individual or collective basis, established in CMN Resolution No. 2,682, of December 21, 1999. Management exercises its judgment in the assessment of the adequacy of the expected loss amounts resulting from models and, according to its experience, makes adjustments that may result from certain clients’ credit condition or from temporary adjustments resulting from new situations or circumstances that have not yet been reflected in modeling. In addition to the default classification the following aspects are also considered: • 12-month horizon, using base macroeconomic scenarios, i.e., with no weighting; and • Highest risk classification according to the operation, client, default, renegotiation, among others. The criteria for the provision for loan losses are detailed in Note 21. IV. Goodwill impairment—The review of goodwill due to impairment reflects the Management’s best estimate for future cash flows of Cash Generating Units (CGU), with the identification of the CGU and estimate of their fair value less costs to sell and/or value in use. To determine this estimate, ITAÚ UNIBANCO HOLDING CONSOLIDATED adopts the discounted cash flow methodology for a period of 5 years, macroeconomic assumptions, growth rate and discount rate. The discount rate generally reflects financial and economic variables, such as the risk-free interest rate and a risk premium. Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 70

Cash-Generating Units or CGU groups are identified at the lowest level at which goodwill is monitored for internal management purposes. V. Deferred income tax and social contribution—deferred tax assets are recognized only in relation to deductible temporary differences, tax losses and social contribution loss carryforwards for offset to the extent that i) it is considered probable that ITAÚ UNIBANCO HOLDING CONSOLIDATED will generate future taxable income for its use; and ii) it presents a history of taxable income or income in at least three of the last five fiscal years. The expected realization of deferred tax assets is based on the projection of future taxable profits and technical studies, as disclosed in Note 11. VI. Defined benefit pension plans—the current amount of pension plans is obtained from actuarial calculations, which use assumptions such as discount rate, which is appropriated at the end of each year and used to determine the present value of estimated future cash outflows. To determine the appropriate discount rate, ITAÚ UNIBANCO HOLDING CONSOLIDATED 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 19. VII. Contingent Assets and Liabilities, Legal Obligations and Tax and Social Security Obligations—ITAÚ UNIBANCO HOLDING CONSOLIDATED periodically reviews its contingencies. These contingencies are evaluated based on management´s best estimates, taking into account the opinion of legal counsel when there is a likelihood that financial resources will be required to settle the obligations and the amounts may be reasonably estimated. Contingencies classified as probable losses are recognized in the Consolidated Balance Sheet under Provisions. Contingent amounts are measured using appropriate models and criteria, despite the uncertainty surrounding the ultimate timing and amounts. Provisions, contingencies and other commitments are detailed in Note 9. VIII. Technical provisions for insurance, pension plan and premium bonds—technical provisions are liabilities arising from obligations of ITAÚ UNIBANCO HOLDING CONSOLIDATED to its policyholders and participants. These obligations may be short term liabilities (property and casualty insurance) or medium and long term liabilities (life insurance and pension plans). The determination of the actuarial liability is subject to several uncertainties inherent in the coverage of insurance and pension contracts, such as assumptions of persistence, mortality, disability, life expectancy, morbidity, expenses, frequency and severity of claims, conversion of benefits into annuities, redemptions and return on assets. The estimates for these assumptions are based on the historical experience of ITAÚ UNIBANCO HOLDING CONSOLIDATED, benchmarks and the experience of the actuary, in order to comply with best market practices and constantly review of the actuarial liability. 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 8. d) Business development Reduction of non-controlling interest in XP Inc. On November 26, 2020, ITAÚ UNIBANCO HOLDING disclosed that the Board of Directors approved the partial spin-off of the investment held in XP Inc. (XP INC) to a new company (XPart S.A.). On December 2 and 17, 2020, ITAÚ UNIBANCO HOLDING sold 4.44% and 0.07%, respectively, of its investments in XP INC, through the public offering on the Nasdaq, giving rising to a result before taxes of R$ 4,001. Concurrently with the sales, XP INC completed a public offering (follow-on) which resulted in the dilution of the interest held by ITAÚ UNIBANCO HOLDING to 41.00% of capital, giving rising to a result in XP INC primary subscription of R$ 546. Additionally, on May 14, 2021, ITAÚ UNIBANCO HOLDING sold 0.48% of its interest in XP INC, generating income before taxes of R$ 486. Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 71

After a favorable opinion of the Federal Reserve Board, XPart S.A. was constituted on May 31, 2021 by the portion of investment in XP INC plus a cash amount corresponding to R$ 10, as approved in the Extraordinary Stockholders’ Meeting held on January 31, 2021. The percentage of XP INC’s capital spun-off to XPart S.A. is 40.52%, which corresponds to XPart S.A. stockholders’ equity value of R$ 9,985 on the base date May 31, 2021. In view of the constitution of XPart S.A., ITAÚ UNIBANCO HOLDING’s stockholders hold an ownership interest in XPart S.A. in the same number, type and proportion of the shares previously held by them in ITAÚ UNIBANCO HOLDING. The shares issued by ITAÚ UNIBANCO HOLDING, as well as the American Depositary Receipts – ADRs, will continue to be traded with the right to receive the shares issued by XPart S.A. until the cut-off date that, once determined, will be informed to the market. After all the events described above, ITAÚ UNIBANCO HOLDING no longer holds an equity interest in XP INC and does not hold any interest in XPart S.A. However, the original agreement establishes an additional acquisition of interest of XP INC in 2022 by ITAÚ UNIBANCO HOLDING, subject to future approval by BACEN, as disclosed in Material Fact of August 10, 2018.

Note 3 – Significant accounting policies a) Cash and cash equivalents - Defined as cash and current accounts with banks, shown in the Consolidated Balance Sheet under the heading Cash, Interbank Deposits and Money Market (Collateral Held) with original maturities not exceeding 90 days. b) Interbank investments, Remunerated restricted Credits held at the Central Bank of Brazil (BACEN), Remunerated deposits, deposits received under securities repurchase agreements, funds from acceptances and issuance of securities, borrowing and onlending, subordinated debt and other receivables and payables – Operations with fixed interest and charges are booked at present value. Operations with floating interest and charges are booked at the adjusted principal amount. Operations subject to foreign exchange variation are booked at the corresponding amount in local currency. Liabilities are presented net of the transaction costs incurred, if significant, calculated pro rata on a daily basis. c) Securities—Recorded at the cost of acquisition restated by the index and/or effective interest rate and presented in the Balance Sheet as required by BACEN Circular 3,068, of November 08, 2001. Securities are classified into the following categories: · Trading securities – Securities acquired to be actively and frequently traded. They are measured at fair value, with a counterparty to the results for the period; · Available for sale securities – Securities that can be negotiated but are not acquired for the purposes of active and frequent trading. They are measured at fair value, with a counterparty to a specific account in stockholders’ equity; · Held to maturity securities – Securities, other than non-redeemable shares, which the bank has the financial capacity and intends, or is required, to hold in the portfolio to maturity. They are recorded at the cost of acquisition, or at fair value, whenever these are transferred from another category. Securities are adjusted up to maturity date, but are not measured at fair value. Gains and losses on available for sale securities, when realized, are recognized on the trade date in the statement of income, with a counterparty to a specific account in stockholders’ equity. Decreases in the fair value of available for sale and held to maturity securities below to cost, resulting from causes not considered to be temporary, are recorded in the results as realized losses. d) Derivative financial instruments—These are classified on the date of their acquisition, according to whether or not management intends to use them for hedging, according to BACEN Circular 3,082, of January 30, 2002. Transactions involving financial instruments, carried out at a customer’s request, for the bank’s own account, or which do not comply with the hedging criteria (mainly derivatives used to manage overall risk exposure), are stated at fair value, including realized and unrealized gains and losses, which are recorded directly in the statement of income. Derivatives that are used for protection against risk exposure or to modify the characteristics of financial assets and liabilities, where changes in fair value are closely related to those of the items being protected at the beginning and throughout the duration of the contract, and which are considered to be effective in reducing the risk exposure in question, are classified as hedges of the following types: · Market Risk Hedge – Financial assets and liabilities, as well as their related financial instruments, are booked at fair value, plus realized and unrealized gains and losses, which are recorded directly in the statement of income; · Cash Flow Hedge—The effective portion of a hedge of financial assets and liabilities, and the related financial instruments, are booked at fair value plus realized and unrealized gains and losses, net of tax effects, when applicable, and recorded in a specific account in stockholders’ equity. The ineffective portion is recorded directly in the statement of income; · Hedge of Net Investments in Foreign Operations—Accounted for similarly to a cash flow hedge, i.e. the portion of gains or losses on a hedging instrument that is determined to be an effective hedge is recognized in stockholders’ equity, and reclassified to income for the period in the event of the disposal of the foreign operation. The ineffective portion is recognized in income for the period. Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 73

e) Loans, leases and other credit operations (operations with lending characteristics) – These transactions are recorded at present value and calculated pro rata on a daily basis in line with variations in a defined indexer and interest rate, and are adjusted up to the 60th day of arrears, according to the expectation of payment. After the 60th day, income is recognized only on actual receipt of payments. Credit card operations include receivables arising from purchases made by cardholders. Funds corresponding to these amounts to be paid to the credit card companies are shown as liabilities, under the heading Interbank Accounts – Receipts and Payments Pending Settlement. f) Provision for loan losses—The balance of the provision for loan losses is recorded based on a credit risk analysis, at an amount considered sufficient to cover loan losses in accordance with the rules determined by CMN Resolution Nº. 2,682 of December 21, 1999, which include the following: · Provisions are recorded from the date on which loans are granted, based on the customer’s risk rating and on a periodic quality assessment of customers and business sectors, and not only in the event of default; · Exclusively in the case of default, losses are written off 360 days after the credits have matured, or after 540 days for operations with maturities longer than 36 months. g) Other assets – They are comprised of Assets Held for Sale, relating to real estate, vehicles and other assets available for sale (owned but deactivated, received as payment in kind or resulting from execution of guarantees). These assets are adjusted to fair value by setting up a provision in accordance with current regulations. This heading also covers Unearned Reinsurance Premiums (Note 3m) and Prepaid Expenses, corresponding to disbursements which will produce benefits in future years. h) Investments – Include goodwill identified in the acquisition of associates and joint ventures, net of any accumulated impairment loss. They are initially recognized at acquisition cost and are subsequently accounted for under the equity method. · Associates: are companies over which ITAÚ UNIBANCO HOLDING CONSOLIDATED has significant influence, but which it does not control. · Joint Ventures: ITAÚ UNIBANCO HOLDING CONSOLIDATED has joint venture whereby the parties that have joint control of the arrangement have rights to the net assets. i) Fixed assets—Are booked at their acquisition cost less accumulated depreciation and adjusted for impairment, if applicable. Depreciation is calculated on the straight-line method using rates based on the estimated useful lives of these assets. Such rates and other details are presented in Note 13. The residual values and useful lives of assets are reviewed and adjusted, if appropriate, at the end of each period. ITAÚ UNIBANCO HOLDING CONSOLIDATED reviews its assets in order to identify indications of impairment in their recoverable amounts. The recoverable amount of an asset is defined as the higher of its fair value less the cost to sell and its value in use. For the purposes of assessing impairment, assets are grouped at the lowest level for which independent cash flows can be identified (cash-generating units). The assessment may be made at an individual asset level when the fair value less the cost to sell can be reliably determined. j) Goodwill – Corresponds to the amount paid in excess in the acquisition of investments and it is amortized based on the expected future profitability or on its realization. It is semiannually submitted to the asset impairment test with the adoption of an approach that involves the identification of cash-generating units (CGU) and the estimate of its fair value less the cost to sell and/or its value in use. The breakdown of intangible assets is described in Note 14. Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 74

k) Intangible assets – Composed of: (i) Goodwill paid upon acquisition of a company, transferred to intangible assets due to merger of the acquired company’s equity into the acquirer company; (ii) Right-of-use, as well as rights on the acquisition of payrolls and association agreements, amortized according to agreement terms or as economic benefits flow to the company; and (iii) Software, amortized over five years, and customer portfolios, amortized within ten years. Intangible assets with definite useful lives are amortized using the straight-line method over their estimated useful lives and those with indefinite useful lives are tested on a semiannually basis to identify possible impairment losses. l) Capital Transactions with Non-Controlling Stockholders - Changes in an ownership interest in a subsidiary, which do not result in a loss of control, are accounted for as capital transactions and any difference between the amount paid and the carrying amount of non-controlling stockholders is recognized directly in consolidated stockholders’ equity. m) Insurance, pension plan and premium bonds operations – Insurance contracts establish, for one of the parties, upon payment (premium) by the other party, the obligation to pay the latter a certain amount in the event of a claim. Insurance risk is defined as a future and uncertain event, of a sudden and unforeseeable nature, independent of the insured’s will, which may cause economic loss when it occurs. Once a contract is classified as an insurance contract, it remains as such until the end of its life, even if the insurance risk is significantly reduced during the period, unless all rights and obligations are extinguished or expire. Insurance premiums, coinsurance accepted and selling expenses are accounted for upon issue of the insurance policy or in accordance with term of the insurance, through the establishment and reversal of a provision for unearned premiums and deferred selling expenses. Interest arising from fractioning of insurance premiums is accounted for as incurred. Revenues from pension contributions, gross revenue from premium bonds certificates and the respective technical provisions are recognized upon receipt. 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. Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 75

If there is evidence of impairment losses with respect to receivables for insurance premiums, ITAÚ UNIBANCO HOLDING CONSOLIDATED 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 CONSOLIDATED 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 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. Acquisition Costs Acquisition costs include direct and indirect costs related to the origination of insurance. These costs are recorded directly in result as incurred, expect 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 corresponding to 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 CONSOLIDATED 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. n) Contingent Assets and Liabilities, Legal Obligations and Tax and Social Security Obligations – these are possible rights and potential obligations arising from past events for which realization depends on uncertain future events. Contingent assets are not recognized in the Consolidated Balance Sheet, except when Management of ITAÚ UNIBANCO HOLDING CONSOLIDATED considers that realization is practically certain. In general they correspond to lawsuits with favorable outcomes in final and unappealable judgments and to the withdrawal of lawsuits as a result of a settlement payment received or an agreement for set-off against an existing liability. These contingencies are evaluated based on Management’s best estimates, and are classified as: · Probable: in which liabilities are recognized in the Consolidated Balance Sheet under Provisions; · Possible: which are disclosed in the Consolidated Financial Statements, but no provision is recorded; · Remote: which require neither a provision nor disclosure. The amount of deposits in guarantee is adjusted in compliance with current legislation. Contingencies guaranteed by indemnity clauses in privatization processes and others, and with liquidity are recognized upon judicial notification with simultaneous recognition of receivables, without any effect on results. Legal Obligations and Tax and Social Security Obligations Represented by amounts payable for tax liabilities, the legality or constitutionality of which are subject to judicial challenge, recognized for the full amount under discussion. Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 76

o) Allowance for Financial Guarantees Provided – Recognized based on the expected loss model, in an amount sufficient to cover any probable losses over the whole guarantee period. p) Income Tax and Social Contribution – There are two components of the provision for income tax and social contribution: current and deferred. The current component is approximately the total of taxes to be paid or recovered during the reporting period. Deferred income tax and social contribution, represented by deferred tax assets and liabilities, is obtained based on the differences between the tax bases of assets and liabilities and the amounts reported in the financial statements at each year end. The income tax and social contribution expense is recognized in the Consolidated statement of income under Income Tax and Social Contribution, except when it refers to items directly recognized in Stockholders’ Equity, such as tax on marking available for sale financial assets to fair value, post-employment benefits and tax on cash flow hedges and hedge of net investment in foreign operations. Subsequently, these items are recognized in income upon realization of the gain/loss on the instruments. Changes in tax legislation and rates are recognized in the Consolidated statement of income under Income tax and social contribution in the period in which they are enacted. Interest and fines are recognized in the Consolidated statement of income under Other administrative expenses. Tax rates, as well as their calculation bases, are detailed in Note 11. q) Deferred income – this refers to: (i) interest received in advance on which there is no prospect of demand for payment and which depends only on the passage of time to be appropriated to effective income, and (ii) the negative goodwill on acquisition of investments, which has not been absorbed in the consolidation process. r) Post-employments benefits Pension plans—defined benefit plans The liability (or asset, as the case may be) is recognized in the consolidated balance sheet with respect to a defined benefit plan corresponds to the present value of the defined benefit obligations at the balance sheet date less the fair value of the plan assets. The defined benefit obligations are calculated annually using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated amount of future cash flows of benefit payments at the rate for Brazilian treasury long term securities denominated in Reais and with maturity periods similar to the term of the pension plan liabilities. Pension plans—defined contribution For defined contribution plans, contributions to plans made by ITAÚ UNIBANCO HOLDING CONSOLIDATED, through pension plan funds, are recognized as expenses, when due. Other post-employment benefit obligations Like defined benefit pension plans, these obligations are assessed annually by independent, qualified actuaries, and the costs expected from these benefits are accrued over the period of employment. Gains and losses arising from changes in practices and variations in actuarial assumptions are recognized in Stockholders’ equity, in the period in which they occur. s) Foreign currency translation I—Functional and presentation currency The Financial Statements of ITAÚ UNIBANCO HOLDING CONSOLIDATED are presented in Brazilian Reais, its functional and presentation currency. For each subsidiary, joint venture or investment in associates, ITAÚ UNIBANCO HOLDING CONSOLIDATED defines the functional currency as the currency of the primary economic environment in which the entity operates. II—Foreign Currency Operations Foreign currency operations are translated into the functional currency using the exchange rates prevailing on the dates of the transactions. Foreign exchange gains and losses are recognized in the Consolidated Statement of Income, unless they are related to cash flow hedges and hedge of net investments in foreign operations, which are recognized in Stockholders’ Equity.

f) Derivative financial instruments ITAÚ UNIBANCO HOLDING CONSOLIDATED trades in derivative financial instruments with various counterparties to manage its overall exposure and to assist its customers in managing their own exposure. Futures – Interest rate and foreign currency futures contracts are commitments to buy or sell a financial instrument at a future date, at an agreed price or yield, and may be settled in cash or through delivery. The notional amount represents the face value of the underlying instrument. Commodity futures contracts or financial instruments are commitments to buy or sell commodities (mainly gold, coffee and orange juice) at a future date, at an agreed price, which are settled in cash. The notional amount represents the quantity of such commodities multiplied by the future price on the contract date. Daily cash settlements of price movements are made for all instruments. Forwards – Interest rate forward contracts are agreements to exchange payments on a specified future date, based on the variation in market interest rates from trade date to contract settlement date. Foreign exchange forward contracts represent agreements to exchange the currency of one country for the currency of another at an agreed price, on an agreed settlement date. Financial instrument forward contracts are commitments to buy or sell a financial instrument on a future date at an agreed price and are settled in cash. Swaps – Interest rate and foreign exchange swap contracts are commitments to settle in cash on a future date or dates the differentials between specific financial indices (either two different interest rates in a single currency or two different rates each in a different currency), as applied to a notional principal amount. Swap contracts shown under Other in the table below correspond substantially to inflation rate swap contracts. Options – Option contracts give the purchaser, for a fee, the right, but not the obligation, to buy or sell a financial instrument within a limited time, including a flow of interest, foreign currencies, commodities, or financial instruments at an agreed price that may also be settled in cash, based on the differential between specific indices. Credit Derivatives – Credit derivatives are financial instruments with value deriving from the credit risk on debt issued by a third party (the reference entity), which permits one party (the buyer of the hedge) to transfer the risk to the counterparty (the seller of the hedge). The seller of the hedge must pay out as provided for in the contract if the reference entity undergoes a credit event, such as bankruptcy, default or debt restructuring. The seller of the hedge receives a premium for the hedge but, on the other hand, assumes the risk that the underlying instrument referenced in the contract undergoes a credit event, and the seller may have to make payment to the purchaser of the hedge for up to the notional amount of the credit derivative. ITAÚ UNIBANCO HOLDING CONSOLIDATED buys and sells credit protection in order to meet the needs of its customers, management and mitigation of its portfolios’ risk. CDS (Credit Default Swap) is a credit derivative in which, upon a default related to the reference entity, the protection buyer is entitled to receive the amount equivalent to the difference between the face value of the CDS contract and the fair value of the liability on the date the contract was settled, also known as the recovered amount. The protection buyer does not need to hold the reference entity’s debt instrument in order to receive the amounts due when a credit event occurs, as per the terms of the CDS contract. TRS (Total Return Swap) is a transaction in which a party swaps the total return of an asset or of a basket of assets for regular cash flows, usually interest and a guarantee against capital loss. In a TRS contract, the parties do not transfer the ownership of the assets. The total value of margins pledged in guarantee by ITAÚ UNIBANCO HOLDING CONSOLIDATED was R$ 8,980 (R$ 14,964 at 12/31/2020) and was basically comprised of government securities. Further information on internal controls and parameters used to manage risks may be found in Note 21—Risk, Capital Management and Fixed Asset Limits.

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

Note 9—Contingent Assets and Liabilities, Legal Obligations and Tax and Social Security Obligations In the ordinary course of its business, ITAÚ UNIBANCO HOLDING CONSOLIDATED 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 provisions and 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 CONSOLIDATED, despite having complied with the rules in force at the time, is a defendant in lawsuits filed by individuals referring to payment of inflation adjustments to savings accounts resulting from economic plants implemented in the 1980s and the 1990s, as well as in collective lawsuits filed by: (i) consumer protection associations; and (ii) the Public Attorney’s Office, on behalf of the savings accounts holders. ITAÚ UNIBANCO HOLDING CONSOLIDATED recognizes provisions upon receipt of summons, and when individuals demand the enforcement of a ruling handed down by the courts, using the same criteria as for provisions for individual lawsuits. 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 CONSOLIDATED has already accepted its terms. Said agreement was approved on March 1, 2018, by the Plenary Session of the Federal Supreme Court (STF) and savers could adhere to its terms for a 24-month period. Due to the end of this term, the parties signed an amendment to the instrument of agreement to extend this period in order to contemplate a higher number of holders of savings accounts and, consequently, to increase the end of lawsuits. In May, 2020 the Federal Supreme Court (STF) approved this amendment and granted a 30-month term for new adhesions, and this term may be extended for another 30 months, subject to the reporting of the number of adhesions over the first period. Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 113

II- Labor claims Provisions and contingencies arise from lawsuits in which labor rights provided for in labor legislation specific to the related profession are discussed, such as: overtime, salary equalization, reinstatement, transfer allowance and, pension plan supplement. These lawsuits are classified as follows: Collective lawsuits: related to claims considered similar and with individual amounts that are not considered significant. The expected amount of loss is determined and accrued on a monthly basis in accordance with a statistical model which calculates the amount of the claims, and is reassessed taking into account court rulings. Provisions and contingencies are adjusted to reflect the amounts deposited into court as security for execution. Individual lawsuits: related to claims with unusual characteristics or involving significant amounts. These are periodically calculated based on the amounts claimed. The probability of loss is estimated in accordance with the actual and legal characteristics of each lawsuit. 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.

Projections of future taxable income include estimates of macroeconomic variables, exchange rates, interest rates, volumes of financial operations and service fees and other factors, which can vary in relation to actual data and amounts. Net income in the financial statements is not directly related to the taxable income for income tax and social contribution, due to differences between accounting criteria and the tax legislation, in addition to corporate aspects. Accordingly, it is recommended that changes in realization of deferred tax assets presented below are not considered as an indication of future net income. IV—At 06/30/2021, deferred tax assets not accounted for correspond to R$ 1,675 and result from Management’s evaluation of their perspectives of realization in the long term (R$ 780 at 12/31/2020). V—Due to the conversion of Provisional Measure (MP) No. 1,034 into Law 14,183/21, the balance of deferred tax assets includes the effect of R$ 1,275 caused by the increase in the rate of the Social Contribution on Net Income (from 20% to 25% for banks and from 15% to 20% for insurance and capitalization companies and other financial institutions) on the assets that will be realized during the effectiveness of the new rate (period from July 1 to December 31, 2021).

ITAÚ UNIBANCO HOLDING CONSOLIDATED recognized on June 30, 2020, adjustments to the recoverable amount of goodwill and intangible assets related to Itaú Corpbanca, in the amounts of R$ 1,593 and R$ 789. The value in use of the Cash Generating Unit (CGU) in which Itáu CorpBanca is allocated was considered and cash flows were based on the result of June 2020 and internal projects of results until 2025. The adjustment to recoverable amount results from economic conditions on June 30, 2020, of Itaú CorpBanca’s market capitalization, discount rates applicable and other changes in variables triggered by the current uncertain macroeconomic condition that, when combined, resulted in a CGU amount lower than its book value. The discount rates used for the impairment test were 10.4% for operations in Chile and 12.3% for operations in Colombia, determined by the cost of capital calculated based on CAPM model. Long-term interest rates considered were 5.2% p.a. and 6.5% p.a. for Chile and Colombia, respectively. The most sensitive assumptions are cost of capital and perpetuity growth rate. Impairment was recognized in the Consolidated Statement of Income under Other operating expenses (Note 10h). Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 132

f) Share-based payment ITAÚ UNIBANCO HOLDING and its subsidiaries have share-based payment plans aimed at involving its management members and employees in the medium and long term corporate development process. The grant of these benefits is only made in years in which there are sufficient profits to permit the distribution of mandatory dividends, limiting dilution to 0.5% of the total shares held by the controlling and minority stockholders at the balance sheet date. These programs are settled through the delivery of ITUB4 treasury shares to stockholders. Expenses on share-based payment plans are presented in the table below: 01/01 to 01/01 to 06/30/2021 06/30/2020 Partner Plan (Note 10f) (52) (97) Share-based plan (192) (200) Total (244) (297) l – Partner Plan The program enables employees and managers of ITAÚ UNIBANCO HOLDING to invest a percentage of their bonus to acquire shares and share-based instruments. There is a lockup period of from three to five years, counted from the initial investment date, and the shares are thus subject to market price variations. After complying with the preconditions outlined in the program, beneficiaries are entitled to receive shares as consideration, in accordance with the number of shares indicated in the regulations. The acquisition price of shares and share-based instruments is established every six months as the average of the share price over the last 30 days, which is performed on the seventh business day prior to the remuneration grant date. The fair value of the consideration in shares is the market price at the grant date, less expected dividends.

II—Variable Compensation In this plan, 50% of variable compensation of managers is paid in cash and 50% is paid in shares for a period of three years. Shares are delivered on a deferred basis, of which one-third per year, will be contingent upon the executive’s permancence in the institution. The deferred unpaid portions may be reversed proportionally to a significant reduction in the recurring income realized or the negative income for the period. Management members become eligible for the receipt of these benefits according to individual performance, business performance or both. The benefit amount is established according to the activities of each management member who should meet at least the performance and conduct requirements. The fair value of the share is the market price at its grant date.

Note 17 – 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. The following table summarizes the book values and estimated fair values for financial instruments: 06/30/2021 12/31/2020 Book value Fair value (*) Book value Fair value Assets Cash (a) 39,837 39,837 46,224 46,224 Central Bank of Brazil Deposits (a) 98,217 98,217 90,059 90,059 Money market (a) 162,283 162,283 238,933 238,933 Interbank deposits (b) 56,180 56,390 55,553 55,751 Trading securities (c) 367,513 367,513 381,598 381,598 Available for sale securities (c) 214,568 214,568 205,491 205,491 Held to maturity securities (c) 75,664 78,419 48,857 52,461 Derivatives financial instruments (c) 70,738 70,738 76,124 76,124 Loan, lease and other credit operations (d) 723,075 727,010 709,799 718,070 (Provision for loan losses) (47,068) (47,068) (51,404) (51,404) Other receivables—Sundry 157 157 6 6 Liabilities Deposits (b) 793,501 793,475 809,010 808,965 Deposits received under securities repurchase agreements (a) 250,190 250,190 280,541 280,541 Funds from acceptances and issuance of securities (b) 127,625 127,660 136,638 136,698 Borrowings and onlending (b) 85,777 85,832 83,200 83,271 Derivatives financial instruments (c) 65,701 65,701 79,599 79,599 Subordinated debts (b) 68,999 70,406 74,916 77,097 Allowance for financial guarantees provided 742 742 754 754 Other liabilities—Sundry 131 131 5 5 (*) In the period, the result of Derivative Financial Instruments, as well as Adjustment to Fair Value of Securities (particularly private securities) had their amounts affected by oscillations of rates and other market variables arising from the impact of the COVID-19 pandemic on the macroeconomic scenario in the period (Note 22d). The methods and assumptions used to estimate the fair value are defined below: a) Cash, Central Bank of Brazil Deposits, Money market and Deposits received under securities repurchase agreements—The carrying amounts for these instruments are close to their fair values. b) Interbank deposits, Deposits, Funds from Acceptances and Issuance of Securities, Borrowings and Onlending and Subordinate Debts – They are calculated by discounting estimated cash flows at market interest rates. c) Securities and Derivatives Financial instruments—Under normal conditions, the prices quoted in the market are the best indicators of the fair values of these financial instruments. However, not all instruments have liquidity or quoted market prices and, in such cases, it is necessary to adopt present value estimates and other techniques to establish their fair value. In the absence of prices quoted by the Brazilian Association of Financial and Capital Markets Entities (ANBIMA), the fair values of government securities are determined based on the interest rates provided by brokers. The fair values of corporate 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) Loan, lease and other credit operations – Fair value is estimated for groups of loans with similar financial and risk characteristics, using valuation models. The fair value of fixed-rate loans was determined by discounting estimated cash flows, at interest rates applicable to similar loans. For the majority of loans at floating rates, the carrying amount was considered to be close to their market value. The fair value of loan and lease operations not overdue was calculated by discounting the expected payments of principal and interest to maturity. The fair value of overdue loan and lease transactions was based on the discount of estimated cash flows, using a rate proportional to the risk associated with the estimated cash flows, or on the underlying collateral. The assumptions for cash flows and discount rates rely on information available in the market and knowledge of the individual debtor. Trading securities and Available for sale securities Level 1: 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 CONSOLIDATED 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 CONSOLIDATED 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 CONSOLIDATED 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.

Transfers to and from Level 3 are presented in movements of Level 3. 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 the inputs used by the service provider. Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 143

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 Bills: In order to mark Financial 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. • Government and Corporate Securities: The pricing process for these securities consists of capturing from 2 to 8 quotas 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 CONSOLIDATED 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. Recurring changes in fair value of Level 3 The tables below show balance sheet changes for financial instruments classified by ITAÚ UNIBANCO HOLDING CONSOLIDATED in Level 3 of the fair value hierarchy. Derivative financial instruments classified in Level 3 correspond to other derivatives indexed to shares.

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 06/30/2021 12/31/2020 Impacts Impacts Market risk factor groups Scenarios Stockholders’ Stockholders’ Income Income equity equity I (0.4) (1.4) (0.1) (1.2) Interest rate II (8.8) (33.6) (1.7) (28.9) III (17.3) (66.7) (2.3) (57.4) I - - - -Commodities, Index and Shares II - - - -I (20.7) - (8.3) -Nonlinear II (33.2) - (11.6) - 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. Commodities, Index and 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 19 – Post-employment benefits ITAÚ UNIBANCO HOLDING CONSOLIDATED, through its subsidiaries, sponsors retirement plans to its employees. Retirement plans are managed by Closed-end Private Pension Entities (EFPC) and are closed to new adhesions. These entities have an independent structure and manage their plans according to the characteristics of their regulations. There are three types of retirement plans: • Defined Benefit Plans (BD): plans which scheduled benefits have their value established in advance, based on salaries and/or length of service of employees, and its cost is actuarially determined; • Defined Contribution Plans (CD): are those plans which scheduled benefits have their value permanently adjusted to the investments balance, kept in favor of the participant, including in the benefit concession phase, considering net proceedings of its investment, amounts contributed and benefits paid; and • Variable Contribution Plans (CV): in this type of plan, scheduled benefits present a combination of characteristics of defined contribution and defined benefit modalities, and the benefit is actuarially determined based on the investments accumulated balance by the participant on the retirement date. Below is a list of benefit plans and their modalities: Entity Benefit Plan Modality Supplementary Retirement Plan Supplementary Retirement Plan – Flexible Premium Annuity Franprev Benefit Plan 002 Benefit Plan Prebeg Benefit Plan Defined Benefit UBB PREV Defined Benefit Plan Benefit Plan II Fundação Itaú Unibanco – Previdência Itaulam Basic Plan Complementar—FIU Itaucard Defined Benefit Plan Itaú Unibanco Main Retirement Plan Itaubanco Defined Contribution Plan Itaubank Retirement Plan Defined Contribution Redecard Pension Plan Unibanco Pension Plan – Intelligent Future Itaulam Supplementary Plan Variable Contribution Itaucard Variable Contribution Plan Itaú Unibanco Supplementary Retirement Plan FUNBEP – Fundo de Pensão Benefit Plan l Defined Benefit Multipatrocinado Benefit Plan ll Variable Contribution Defined Contribution plans include pension funds consisting of the portions of sponsor’s contributions not included in a participant’s account balance due to loss of eligibility for the benefit, and of monies arising from the migration of retirement plans in defined benefit modality. These funds are used for future contributions to individual participants’ accounts, according to the respective benefit plan regulations.

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. 06/30/2021 06/30/2020 Discount rate (1) 7.64% p.a. 7.64% p.a. Mortality table (2) AT-2000 AT-2000 Turnover (3) Itaú Experience 2008/2010 Itaú Experience 2008/2010 Future salary growth 4.00% to 7.12 % p.a. 4.00% to 7.12 % 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”, by applying 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-term characteristics and the main factors involved in the management and measurement of their risks are financial risk, inflation risk and demographic risk. - Financial Risk – the actuarial liability of the plan is calculated by adopting a discount rate, which may differ from rates earned in investments. If real income from plan investments is lower than yield expected, this may give rise to a deficit. To mitigate this risk and assure the capacity to pay long-term benefits, the plans have a significant percentage of fixed-income securities pegged to the plan commitments, aiming at minimizing volatility and risk of mismatch between assets and liabilities. Additionally, adherence tests are carried out in financial assumptions to ensure their adequacy to obligations of respective plans. - Inflation risk – a large part of liabilities is pegged to inflation risk, making actuarial liabilities sensitive to increase in rates. To mitigate this risk, the same financial risks mitigation strategies are used. - Demographic Risk – plans that have any obligation actuarially assessed are exposed to demographic risk. In the event the mortality tables used are not adherent to the mass of plan participants, a deficit or surplus may arise in actuarial evaluation. To mitigate this risk, adherence tests to demographic assumptions are conducted to ensure their adequacy to liabilities of respective plans. For purposes of registering in the balance sheet the EFPCs that manage them, actuarial liabilities of plans use discount rate adherent to its asset portfolio and income and expense flows, according to a study prepared by an independent consulting company. The actuarial method used is the aggregate method, through which the plan costing Is defined by the difference between its equity coverage and the current value of its future liabilities. Observing the methodology established in the respective actuarial technical note. 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. Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 148

c) Asset management The purpose of the management of the funds is the long-term balance between pension assets and liabilities with payment of benefits by exceeding actuarial goals (discount rate plus benefit adjustment index, established in the plan regulations). Below is a table with the allocation of assets by category, segmented into Quoted in an Active Market and Not Quoted in an Active Market: Fair value % Allocation Types 06/30/2021 12/31/2020 06/30/2021 12/31/2020 Fixed income securities 21,026 21,172 89.6% 91.2% Quoted in an active market 20,541 20,804 87.5% 89.6% Non quoted in an active market 485 368 2.1% 1.6% Variable income securities 1,768 1,387 7.6% 5.9% Quoted in an active market 1,756 1,378 7.5% 5.9% Non quoted in an active market 12 9 0.1% 0.0% Structured investments 122 82 0.5% 0.4% Quoted in an active market - - 0.0% 0.0% Non quoted in an active market 122 82 0.5% 0.4% Real estate 468 506 2.0% 2.2% Loans to participants 77 78 0.3% 0.3% Total 23,461 23,225 100.0% 100.0% The defined benefit plan assets include shares of ITAÚ UNIBANCO HOLDING, its main parent company (ITAÚSA) and of subsidiaries of the latter, with a fair value of R$ 11 (R$ 11 at 12/31/2020), and real estate rented to Group companies, with a fair value of R$ 388 (R$ 410 at 12/31/2020). d) Other post-employment benefits ITAÚ UNIBANCO HOLDING CONSOLIDATED does not have additional liabilities related to post-employment benefits, except in cases arising from maintenance commitments assumed in acquisition agreements occurred over the years, as well as those benefits originated from court decision in the terms and conditions established, in which there is total or partial sponsorship of health care plan for a specific mass of former employees and their beneficiaries. Its costing is actuarially determined so as to ensure coverage maintenance. These plans are closed to new applicants. Assumptions for discount rate, inflation, mortality table and actuarial method are the same used for retirement plans. ITAÚ UNIBANCO HOLDING CONSOLIDATED used the percentage of 4% p.a. for medical inflation and the percentage of 3% p.a. for aging factor, additionally considering, inflation rate of 4% p.a. Particularly in other post-employment benefits, there is medical inflation risk associated to increase in medical costs above expectation. To mitigate this risk, the same financial risks mitigation strategies are used. Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 149

These processes are aligned with the guidelines of the Board of Directors and Executive which, through collegiate bodies, define the global objectives expressed as targets and limits for the business units that manage risk. Control and capital management units, in turn, support ITAÚ UNIBANCO HOLDING CONSOLIDATED’s management by monitoring and analyzing risk and capital. The Board of Directors is the main body responsible for establishing guidelines, policies and approval levels for risk and capital management. The Risk and Capital Management Committee (CGRC), in turn, is responsible for supporting the Board of Directors in managing capital and risk. At the executive level, collegiate bodies, presided over by the Chief Executive Officer (CEO) of ITAÚ UNIBANCO HOLDING CONSOLIDATED, are responsible for capital and risk management, and their decisions are monitored by the CGRC. Additionally, ITAÚ UNIBANCO HOLDING CONSOLIDATED has collegiate bodies with capital and risk management responsibilities delegated to them, under the responsibility of CRO (Chief Risk Officer). To support this structure, the Risk Area 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 CONSOLIDATED 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.” Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 152

Based on this statement, five dimensions have been defined (Capitalization, Liquidity, Composition of Earnings, Operating Risk and Reputation). Each dimension consists of a set of metrics associated with the main risks involved, combining supplementary measurement methods, to give a comprehensive vision of our exposure. The Board of Directors is responsible for approving guidelines and limits for risk appetite, with the support of CGRC and the CRO (Chief Risk Officer). The limits for risk appetite are monitored regularly and reported to risk committees and to the Board of Directors, which will oversee the preventive measures to be taken to ensure that exposure is aligned with the strategies of ITAÚ UNIBANCO HOLDING CONSOLIDATED. Foremost among BACEN’s requirements for proper risk and capital management are the Risk Appetite Statement (RAS) and the implementation of a continuous, integrated risk management structure, the stress test program, the establishment of a Risk Committee, and the nomination at BACEN of a Chief Risk Officer (CRO), with roles and responsibilities assigned, and requirements for independence. Risk appetite, risk management and guidelines for employees of ITAÚ UNIBANCO HOLDING CONSOLIDATED for routine decision-making purposes are based on: · Sustainability and customer satisfaction: ITAÚ UNIBANCO HOLDING CONSOLIDATED’s vision is to be the leading bank in sustainable performance and customer satisfaction and, accordingly, we are committed to creating shared value for staff, customers, stockholders and society, ensuring the continuity of the business. ITAÚ UNIBANCO HOLDING CONSOLIDATED is committed to doing business that is good both for the customer and the institution itself; · Risk culture: ITAÚ UNIBANCO HOLDING CONSOLIDATED’s risk culture goes beyond policies, procedures or processes, reinforcing the individual and collective responsibility of all employees so that they will do the right thing at the right time and in the proper manner, respecting the ethical way of doing business; · Risk pricing: ITAÚ UNIBANCO HOLDING CONSOLIDATED’s operates and assumes risks in business that it knows and understands, avoids the ones that are unknown or that do not provide competitive advantages, and carefully assesses risk-return ratios; · Diversification: ITAÚ UNIBANCO HOLDING CONSOLIDATED has little appetite for volatility in earnings, and it therefore operates with a diverse base of customers, products and business, seeking to diversify risks and giving priority to lower risk business; · Operational excellence: It is the wish of ITAÚ UNIBANCO HOLDING CONSOLIDATED to be an agile bank, with a robust and stable infrastructure enabling us to offer top quality services; · Ethics and respect for regulation: for ITAÚ UNIBANCO HOLDING CONSOLIDATED, ethics is 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 CONSOLIDATED has various ways of disseminating risk culture, based on four principles: conscious risk-taking, discussion of the risks the institution faces, the corresponding action taken, and the responsibility of everyone for managing risk. These principles serve as a basis for ITAÚ UNIBANCO HOLDING CONSOLIDATED’s guidelines, helping employees to conscientiously understand, identify, measure, manage and mitigate risks. I – Credit risk The possibility of losses arising from failure by a borrower, issuer or counterparty to meet their financial obligations, the impairment of a loan due to downgrading of the risk rating of the borrower, the issuer or the counterparty, a decrease in earnings or remuneration, advantages conceded on renegotiation or the costs of recovery. There is a credit risk control and management structure, centralized and independent from the business units, that provides for operating limits and risk mitigation mechanisms, and also establishes processes and tools to measure, monitor and control the credit risk inherent in all products, portfolio concentrations and impacts of potential changes in the economic environment. Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 153

The credit policy of ITAÚ UNIBANCO HOLDING CONSOLIDATED is based on internal criteria such as: classification of customers, portfolio performance and changes, default levels, rate of return and economic capital allocated, and external factors such as interest rates, market default indicators, inflation, changes in consumption, and so on. In compliance with CMN Resolution 4,557, of February 23, 2017, the document “Public Access Report – Credit Risk”, which includes the guidelines established by our credit risk control policy, can be viewed at www.itau.com.br/investor-relations, in the section Itaú Unibanco, under Corporate Governance, Regulations and Policies, Reports. II—Market risk The possibility of incurring financial losses from changes in the market value of positions held by a financial institution, including the risks of transactions subject to fluctuations in currency rates, interest rates, share prices, price indexes and commodity prices, as set forth by CMN. Price Indexes are also treated as a risk factor group. Market risk is controlled by an area independent from the business areas, which is responsible for the daily activities of (i) risk measurement and assessment, (ii) monitoring of stress scenarios, limits and alerts, (iii) application, analysis and testing of stress scenarios, (iv) risk reporting to those responsible within the business areas, in compliance with the governance of ITAÚ UNIBANCO HOLDING CONSOLIDATED, (v) monitoring of actions required to adjust positions and risk levels to make them realistic, and (vi) providing support for the safe launch of new financial products. The market risk structure categorizes transactions as part of either the banking portfolio or the trading portfolio, in accordance with general criteria established by CMN Resolution 4,557, of February 23, 2017, and BACEN Circular 3,354, of June 27, 2007. The trading portfolio consists of all transactions involving financial instruments and commodities, including derivatives, which are held for trading. The banking portfolio is basically characterized by transactions for the banking business, and transactions related to the management of the balance sheet of the institution, where there is no intention of sale and time horizons are medium and long term. Market risk management is based on the following metrics: · Value at risk (VaR): a statistical measure that estimates the expected maximum potential economic loss under normal market conditions, considering a certain time horizon and confidence level; · Losses in stress scenarios (Stress Test): simulation technique to assess the behavior of assets, liabilities and derivatives of a portfolio when several risk factors are taken to extreme market situations (based on prospective and historical scenarios); · Stop loss: metric used to revise positions, should losses accumulated in a fixed period reach a certain level; · Concentration: cumulative exposure of a certain financial instrument or risk factor, calculated at fair value (MtM – Mark to Market); and · Stressed VaR: statistical metric derived from the VaR calculation, with the purpose is of simulating higher risk in the trading portfolio, taking returns that can be seen in past scenarios of extreme volatility. Management of interest rate risk in the Banking Book (IRRBB) is based on the following metrics: · ÄEVE (Delta Economic Value of Equity): difference between the present value of the sum of repricing flows of instruments subject to IRRBB in a base scenario and the present value of the sum of repricing flows of these instruments in a scenario of shock in interest rates; · ÄNII (Delta Net Interest Income): difference between the result of financial intermediation of instruments subject to IRRBB in a base scenario and the result of financial intermediation of these instruments in a scenario of shock in interest rates. In addition, sensitivity and loss control measures are also analyzed. They include: · Mismatching analysis (GAPS): accumulated exposure by risk factor of cash flows expressed at fair value, allocated at the maturity dates; Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 154

· Sensitivity (DV01- Delta Variation): impact on the fair value of cash flows when a 1 basis point change is applied to current interest rates or on the index rates; and · Sensitivity to Sundry Risk Factors (Greeks): partial derivatives of an option portfolio in relation to the prices of underlying assets, implied volatilities, interest rates and time. In order to operate within the defined limits, ITAÚ UNIBANCO HOLDING CONSOLIDATED hedges transactions with customers and proprietary positions, including its foreign investments. Derivatives are commonly used for these hedging activities, which can be either accounting or economic hedges, both governed by the institutional polices of ITAÚ UNIBANCO HOLDING CONSOLIDATED (Note 5 – Securities and derivative financial instruments). The structure of limits and alerts obeys the Board of Directors’ guidelines, and it is reviewed and approved on an annual basis. This structure has specific limits aimed at improving the process of monitoring and understanding risk, and at avoiding concentration. These limits are quantified by assessing the forecast balance sheet results, the size of stockholders’ equity, market liquidity, complexity and volatility, and ITAU UNIBANCO HOLDING CONSOLIDATED’s appetite for risk. The consumption of market risk limits is monitored and disclosed daily through exposure and sensitivity maps. The market risk area analyzes and controls the adherence of these exposures to limits and alerts and reports them timely to the Treasury desks and other structures foreseen in the governance. ITAÚ UNIBANCO HOLDING CONSOLIDATED uses proprietary systems to measure the consolidated market risk. The processing of these systems occurs in a high-availability access-controlled environment, which has data storage and recovery processes and an infrastructure that ensures business continuity in contingency (disaster recovery) situations. At 06/30/2021, ITAÚ UNIBANCO HOLDING CONSOLIDATED presented a Total VaR of R$ 479, an increase in relation to prior year (R$ 223 at 12/31/2020) due to higher exposure in interest rates. The document “Public Access Report – Market Risk“, which includes which includes our internal policy guidelines for market risk control, is not an integral part of the financial statements, but can be viewed at www.itau.com.br/investor-relations, in the section Itaú Unibanco, Corporate Governance, Regulations and Policies, Reports. III – Liquidity risk The possibility that the institution may be unable to efficiently meet its expected and unexpected obligations, both current and future, including those arising from guarantees issued, without affecting its daily operations and without incurring significant losses. Liquidity risk is controlled by an area independent from the business area and responsible for establishing the reserve composition, estimating the cash flow and exposure to liquidity risk in different time horizons, and for monitoring the minimum limits to absorb losses in stress scenarios for each country where ITAÚ UNIBANCO HOLDING CONSOLIDATED operates. All activities are subject to verification by independent validation, internal control and audit areas. The document Public Access Report—Liquidity Risk, which includes our internal policy guidelines for liquidity risk control, is not an integral part of the financial statements, but can be viewed on the website www.itau.com.br/investor-relations, in the section Itaú Unibanco, Corporate Governance, Regulations and Policies, Reports.

IV – Operating risk Defined as the possibility of losses from failures, defects or shortcomings in internal processes, people or systems, or from external events impacting the realization of strategic, tactical or operational objectives. It includes the legal risk of inadequacies or defects in agreements signed by the institution, as well as sanctions for failing to comply with legal provisions and compensation to third parties for losses arising from the institution’s activities. The managers of executive areas use corporate methods developed and supplied by the internal controls, compliance and operating risk area. As part of governance of the risk management process, consolidated reports on risk monitoring, controls, action plans and operating losses are periodically presented to the business areas’ executives. In line with the principles of CMN Resolution 4,557, of February, 23, 2017, the document entitled “Public Access Report – Integrated Operational Risk Management and Internal Controls”, a summarized version of the institutional operating risk management policy, may be viewed on the website www.itau.com.br/investor-relations, in the section Itaú Unibanco, Corporate Governance, Regulations and Policies, Reports. V—Insurance, private pension and premium bonds risks The main risks related to Insurance, Private Pension and Premium Bonds portfolios are described below and defined in their respective chapters. · Underwriting risk: possibility of losses arising from insurance, pension plan and premium bonds operations contrary to the institution’s expectations of ITAÚ UNIBANCO HOLDING CONSOLIDATED, directly or indirectly associated with technical and actuarial bases adopted to calculate premiums, contributions and provisions; · Credit risk; · Market risk; · Liquidity risk; · Operating risk. These risks are managed independently, according to their special characteristics. VI – Social and Environmental Risk ITAÚ UNIBANCO HOLDING CONSOLIDATED understands the Social and Environmental risk as the possibility of losses incurred due to social and/or environmental events related to the activities developed by the institution, pursuant to CMN Resolution 4,327/14. The Policy on Sustainability and Social and Environmental Responsibility (PRSA) establishes the guidelines, strategies and underlying principles for social and environmental management, based on institutional issues and addressing, through specific procedures, the most significant risks for the Institution’s operation. Actions to mitigate the Social and Environmental Risk are taken based on the mapping of processes, risks and controls, monitoring of new standards related to the theme and record of occurrence sin internal systems. In addition to the identification, the phases of prioritization, response to risk, monitoring and reporting of assessed risks supplement the management of this risk at ITAÚ UNIBANCO HOLDING CONSOLIDATED. The management of social and environmental risk adopts the strategy of three defense lines: the first defense line (business areas) manages the risk in its daily activities, following the PRSA guidelines, specific processes, with the support of specialized assessment from dedicated technical teams located in Corporate Compliance, Credit Risk and Modeling, and Institutional Legal teams, that act on an integrated way in the management of all dimensions of the Social and Environmental Risk related to the conglomerate’s activities. As an example of the specific guidelines to manage this risk, business units count on the governance for approval of new products and services, which contemplates, in its assessments, the Social and Environmental Risk, ensuring the compliance with this requirement in new products approved by the Institution, as well as specific social and environmental procedures for the Institution’s operation (stockholders’ equity, branch infrastructure and technology), suppliers, credit, investments and key controls. The second line of defense, in turn, is represented by the Credit Risk and Modeling, by Internal Controls, as well as Compliance, through the Corporate Social and Environmental Risk Management, which supports and ensures the governance of the first line’s activities. The third line of defense composed of the Internal Audit, acts on an independent manner, mapping and assessing risk management, controls and governance. Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 156

Governance also counts on the Social and Environmental Risk Committee, whose main responsibility is to assess and deliberate about institutional and strategic matters, as well as to resolve on products, operations, and services, among others involving the Social and Environmental Risk, including Climate Risk. Further details on environmental and social risk, which is not an integral part of the financial statements, can be viewed at www.itau.com.br/investor-relations, section Results and Reports, Regulatory Reports, Pillar 3 and Global Systemically Important Banks / Risk and Capital Management – Pillar 3. c) Capital management governance ITAÚ UNIBANCO HOLDING CONSOLIDATED is subject to the regulations of BACEN, which determines minimum capital requirements, procedures to obtain information to assess the global systemic importance of banks, fixed asset limits, loan limits and accounting practices, and requires banks to conform to the regulations based on the Basel Accord for capital adequacy. Additionally, CNSP and SUSEP issue regulations on capital requirements that affect our insurance operations and private pension and premium bonds plans. The capital statements were prepared in accordance with BACEN’s regulatory requirements and with internationally accepted minimum requirements according to the Bank for International Settlements (BIS). I – Composition and Capital Adequacy The Board of Directors is the body responsible for approving the institutional capital management policy and guidelines for the capitalization level of ITAÚ UNIBANCO HOLDING CONSOLIDATED. The Board is also responsible for the full approval of the ICAAP (Internal Capital Adequacy Assessment Process) report, the purpose of which is to assess the capital adequacy of ITAÚ UNIBANCO HOLDING CONSOLIDATED. The result of the last ICAAP, which comprises stress tests – which was dated December 2020 – indicated that ITAÚ UNIBANCO HOLDING CONSOLIDATED has, in addition to capital to cover all material risks, a significant capital surplus, thus assuring the solidity of the institution’s equity position. In order to ensure that ITAÚ UNIBANCO HOLDING CONSOLIDATED is sound and has the capital needed to support business growth, the institution maintains PR levels above the minimum level required to face risks, as demonstrated by the Common Equity, Tier I Capital and Basel ratios. 06/30/2021 12/31/2020 Available capital (amounts) Common Equity Tier 1 124,964 119,960 Tier 1 141,674 137,157 Total capital (PR) 156,561 151,244 Risk-weighted assets (amounts) Total risk-weighted assets (RWA) 1,048,628 1,042,207 Risk-based capital ratios as a percentage of RWA Common Equity Tier 1 ratio (%) 11.9% 11.5% Tier 1 ratio (%) 13.5% 13.2% Total capital ratio (%) 14.9% 14.5% Additional CET1 buffer requirements as a percentage of RWA Capital conservation buffer requirement (%) (*) 1.625% 1.25% Countercyclical buffer requirement (%) 0.0% 0.0% Bank G-SIB and/or D-SIB additional requirements (%) 1.0% 1.0% Total of bank CET1 specific buffer requirements (%) 2.625% 2.25% (*) For purposes of calculating the Conservation capital buffer, BACEN Resolution 4,783 establishes, for defined periods, percentages to be applied to the RWA value with a gradual increase until April/2022, when it reaches 2.5%. The Basel Ratio reached 14.9% on June 30, 2021, with an increase of 0.4 percentage point as compared to December 31, 2020. The main positive effects were the accumulated income for the period, net of mandatory minimum dividends and issues of Tier II Subordinated Notes, partially offset by the exchange variation on Tier I Subordinated Notes and an increase in credit risk weighted assets. Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 157

Additionally, ITAÚ UNIBANCO HOLDING CONSOLIDATED has a surplus over the required minimum Referential Equity of R$ 72,671 (R$ 67,867 at 12/31/2020), well above the ACP of R$ 27,526 (R$ 23,450 at 12/31/2020), generously covered by available capital. The fixed assets ratio shows the commitment percentage of adjusted Referential Equity with adjusted permanent assets. ITAÚ UNIBANCO HOLDING CONSOLIDATED falls within the maximum limit of 50% of adjusted PR, established by BACEN. At 06/30/2021, fixed assets ratio reached 18.0% (24.0% at 12/31/2020), showing a surplus of R$ 50,177 (R$ 39,274 at 12/31/2020).

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

ITAÚ UNIBANCO HOLDING CONSOLIDATED identified the following impacts on its results, as well as effects on estimates and critical judgments for the preparation of the Consolidated Financial Statements: (a) increase in 2020 in loan and financing operations, especially for micro, small and medium-sized companies due to the measures adopted for mitigation of the impacts of COVID-19 by the authorities with the creation of programs such as PESE, PRONAMPE, PEAC-FGI e CGPE, which balance in June 2021 is R$ 22,288. Through timely monitoring of credit standards and behavior of clients, ITAÚ UNIBANCO HOLDING CONSOLIDATED maintained the regularity of its operations, despite the adverse conditions, and helped clients in the sustainable search for their financial rebalancing; (b) with the purpose of treating indebtedness in a structured way and giving financial impetus to clients, initiatives were established that allowed the extension of grace periods, terms and better interest rate conditions for individuals, and micro and small business clients. In June 2021 this portfolio amount to R$ 40.7 billion. In March 2020, the Program 60+ was established, which, among other measures, allowed a 60-day grace period for defaulting agreements and in mid-April the Travessia (Crossing) Program. Travessia allowed the extension of grace periods between 120 and 180 days and terms of operations between 5 and 6 years, respectively, for individual and micro and small companies clients, under better interest rate conditions; (c) 0.9% increase in the period in applications of renegotiation and extension of terms for loan operations as the economic situation changed. In June 2021, 77.2% of the loan operations portfolio generated by means of these initiatives was current, 3.2% was in a grace period, 6.9% was past due between 15 and 90 days and 12.7% was past due for over 90 days; (d) the allowance for loan losses in the amount of R$ 47,810 was affected due to the level of risk and default, due to the changes in the financial perspectives of clients and the visible deterioration of macroeconomic variables. To fully reflect the risk of its loan operations, ITAÚ UNIBANCO HOLDING CONSOLIDATED adopts the expected loss model for provisioning of operations since the moment they are granted and it is periodically updated according to the macroeconomic variables and circumstances of the client, and in 2020, in view of the pandemic, a weighting in the economic scenarios was added. In June 2021, the level of coverage of provisions in the loan portfolio of ITAÚ UNIBANCO HOLDING CONSOLIDATED accounted for 283% as compared to 320% in December 2020. Specifically for the expected loss of operations that have not shown any signs of deterioration so far (default or downgrading of the client’s rating), provisioning posted a decrease of 17.9% in the period. The credit risk governance allowed ITAÚ UNIBANCO HOLDING CONSOLIDATED a quick response for monitoring the impacts of the COVID-19 pandemic on the loan portfolio, permitting quick access to the information needed for discussions and actions of the crisis management daily forums; (e) the mark-to-market component of the securities portfolio was -0.5% in the first quarter of 2020, partially due to rate fluctuations and high price volatility in the markets in the beginning of the pandemic, influencing the measurement of items stated at fair value in their different levels. In subsequent periods, variations observed in the mark-to-market component are not necessarily related to the effects of the pandemic; (f) due to the COVID-19 pandemic, during 2020, the instability in the variable income market was noted causing a migration to fixed income instruments with liquidity. This movement resulted in the increase in the Bank Deposit Certificates portfolio; however, over 2021, a small drop was noted as the portfolio gets back to normal. Additionally, there were impacts on funding, with an increase in deposits too. With the purpose of mitigating the system’s liquidity risk, BACEN made available in 2020 to financial institutions credit lines through repurchase agreements in foreign currency and purchase of financial bills with guarantee, and operations in the total amount of R$ 30,547 were contracted during the period of life of these lines; (g) increase in the recognition of deferred income tax and social contribution in 2020 due to the greater volume of deductible temporary differences recorded for the period. The pandemic reduced the projections of taxable income, however, it was not responsible for the generation of tax loss and social contribution loss carryforwards in ITAÚ UNIBANCO HOLDING CONSOLIDATED. In the period, there were no significant impacts of the pandemic in the recognition of deferred income tax and social contribution in ITAÚ UNIBANCO HOLDING CONSOLIDATED; and (h) increase in expenses with claims related to COVID-19 of R$ 219 in the period, mainly related to credit life and life insurance.

There was a reduction in the face-to-face service staff and an increase in the spacing between people in call centers to reduce the circulation of people and the possibilities of contagion. The average number of people circulating in administrative centers was reduced, since they started to work remotely. Employees in the central management, service centers and digital branches are substantially working from home. It should be noted that despite the aforementioned measures, ITAÚ UNIBANCO HOLDING CONSOLIDATED maintains its operating activities. In order to reduce the effects of the crisis and ensure the employee’s health and safety, self-declaration was encouraged for employees who consider themselves at risk and those who cannot work remotely were put on vacation. In 2020, with the purpose of supporting those who possibly had additional expenses due to the current crisis, the 13th salary was advanced in full. Additionally, a process of communication and transparency with employees was established through e-mails, internal employee’s portal and periodic videos prepared by our Chief Executive Officer communicating news related to COVID-19. At the branches, masks were delivered to all employees who work in customer service, acrylic protections were implemented and cleaning protocols were reviewed. The adaptation of ITAÚ UNIBANCO HOLDING CONSOLIDATED in the crisis is the result not only of investments in technology, which allows for these virtual interactions, but also of investments in flexibility in the work environment, such as work from home, communities integrated between different areas of the bank and new layouts in the administrative centers that promote the employees’ mobility. In 2020, ITAÚ UNIBANCO HOLDING CONSOLIDATED created the initiative “Todos pela Saúde” (All for Health) from the donation of R$ 1 billion, with the purpose of combating the new Coronavirus and its effects on Brazilian society. “Todos Pela Saúde” is conducted based on four axes: Informing, Protecting, Caring, and Resuming. In February 2021, the “Todos pela Saúde” initiative was formalized as an Institute, and ongoing actions are being maintained. The mission of the “Todos pela Saúde” Institute is to contribute to strengthening and innovation in the health surveillance area in Brazil. The activities to be developed include both research funding and genomic (or metagenomic) surveys, in addition to the training of field epidemiologists. In April 2021, ITAÚ UNIBANCO HOLDING CONSOLIDATED worked together with competitors to combat hunger resulting from the pandemic and the economic crisis. ITAÚ UNIBANCO HOLDING CONSOLIDATED contributed for the purchase and distribution of food staples. e) Regulatory non-recurring result Presentation of regulatory non-recurring result of ITAÚ UNIBANCO HOLDING and ITAÚ UNIBANCO HOLDING CONSOLIDATED, net of tax effects, in accordance with the criteria established by BCB Resolution No. 2/2020: 01/01 to 01/01 to 06/30/2021 06/30/2020 Regulatory non-recurring result 436 (799) Revaluation of deferred tax assets increase in social contribution) Social Contribution 1,275 -Provision for restructuring (747) -Donation to “Todos pela Saúde” (“All for Health”)—(834) Reclassification – Investment IRB—379 Mark to market of collateralized securities—(307) Impairment of goodwill and intangible assets – Itaú CorpBanca—(19) Other (92) (18) Itaú Unibanco Holding S.A. – Complete Financial Statements – June 30, 2021 162

Itaú Unibanco Holding S.A. Why it is a Key Audit Matter How the matter was addressed in the audit involved, as described above, in determining, recording and disclosing the required items, we continue to consider this an area of audit focus. Others matters Statements of added value The parent company and consolidated statements of added value for the six-month period ended on June 30, 2021, prepared under the responsibility of the Bank’s management, which presentation is required by the Brazilian Corporate Law for listed companies and treated as supplementary information for purposes of BACEN, were submitted to audit procedures performed in conjunction with the audit of the financial statements. For the purposes of forming our opinion, we evaluated whether these statements are reconciled with the financial statements and accounting records, as applicable, and if their form and content are in accordance with the criteria defined in Technical Pronouncement CPC 09, “Statement of Added Value”. In our opinion, these statements of added value have been properly prepared, in all material respects, in accordance with the criteria established in the Technical Pronouncement and are consistent with the parent company and consolidated financial statements taken as a whole. Other information accompanying the parent company and consolidated financial statements and the auditor’s report The Bank’s management is responsible for the other information which comprise the Management Report and the Management Discussion and Analysis Report. Our opinion on the parent company and consolidated financial statements does not cover the Management Report or the Management Discussion and Analysis Report, and we do not express any form of audit conclusion thereon. In connection with the audit of the parent company and consolidated financial statements, our responsibility is to read the Management Report and the Management Discussion and Analysis Report and, in doing so, consider whether these reports are materially inconsistent with the financial statements or our knowledge obtained in the audit or otherwise appear to be materially misstated. If, based on the work we have performed, we conclude that there is a material misstatement in the Management Report or in the Management Discussion and Analysis Report, we are required to report that fact. We have nothing to report in this regard. Responsibilities of management and those charged with governance for the parent company and consolidated financial statements Management is responsible for the preparation and fair presentation of the parent company and consolidated financial statements in accordance with accounting practices adopted in Brazil applicable to institutions authorized to operate by BACEN, and for such internal control as Management determines is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

Itaú Unibanco Holding S.A. In preparing the parent company and consolidated financial statements, Management is responsible for assessing the Bank’s ability to continue as going concerns, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless Management either intends to liquidate the Bank or to cease operations, or has no realistic alternative but to do so. Those charged with governance in the Bank and its subsidiaries are responsible for overseeing the financial reporting process. Auditor’s responsibilities for the audit of the parent company and consolidated financial statements Our objectives are to obtain reasonable assurance about whether the parent company and the consolidated financial statements, as a whole, are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that the audit conducted in accordance with the Brazilian and International Standards on Auditing will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements. As part of an audit in accordance with Brazilian and International Standards on Auditing, we exercise professional judgment and maintain professional skepticism throughout the audit. We also: • Identify and assess the risks of material misstatement of the parent company and consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. • Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the internal control of the Bank and its subsidiaries. • Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by Management. • Conclude on the appropriateness of Management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Bank’s ability to continue as going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the parent company and consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Bank and its subsidiaries to cease to continue as going concern. • Evaluate the overall presentation, structure and content of the parent company and consolidated financial statements, including the disclosures, and whether the financial statements represent the underlying transactions and events in a manner that achieves fair presentation. • Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Consolidated to express an opinion on the parent company and consolidated financial statements. We are responsible for the direction, supervision and performance of the group audit. We remain solely responsible for our audit opinion.

Itaú Unibanco Holding S.A. We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit. We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence and that we communicated to them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards. From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the parent company and consolidated financial statements of the half-year ended June 30, 2021 and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.
