5.6. Supply other information that the issuer may deem relevant On August 21, 2017, CMN Resolution No. 4,557, which provides for the risk and capital management structure, came into effect. Noteworthy in this resolution are the implementation of a continuous, integrated risk management framework, the requirements for defining the Risk Appetite Statement (RAS) and the stress testing program, the set-up of a Risk Committee, the nomination of the Chief Risk Officer (CRO) to be reported to the Central Bank of Brazil, and the CRO's roles, responsibilities and independence requirements. Additional information on items 5.1 and 5.5 COVID-19 relief efforts We have monitored the economic impacts of the Covid-19 pandemic in Brazil and other countries where we operate that may adversely affect our results. From the onset of the Covid-19 outbreak in Brazil, we have acted and structured the Institutional Crisis Management Committee. The Executive Committee has set out an intense agenda focused on responsible crisis management, by monitoring the pandemic and its impacts on our operations, in addition to the government measures to mitigate the effects of the pandemic. Over 2020 and 2021, some measures to mitigate the impacts of the Covid-19 pandemic in Brazil were adopted by the Federal Government, National Monetary Council (CMN), and the Central Bank of Brazil (BACEN), notably: CMN Resolution No. 4782/20, as amended by CMN Resolutions No. 4791/20 and No. 4,856/20, which set out, for a determined period of time, the criteria for characterizing restructuring of loan operations; CMN Resolution No. 4,838/20, which regulates the Working Capital for Business Continuity (CGPE) Program; CMN Resolution No. 4,846/20, which provides for loan operations for financing of payroll carried out by financial institutions, under the Emergency Employment Support Program (PESE); Law No. 13,999/20 and amendment made by Law 14,161/21, which introduced the National Support Program for very small and small companies (Pronampe) aimed at developing and strengthening small businesses; Law No. 14,042/20, which set out the Emergency Program for Access to Credit (Peac), with the purpose of easing access to credit and preserving companies, for the protection of jobs and income. The Peac has two modalities: Emergency Program for Access to Credit in the modality of guarantee (Peac-FGI) and Emergency Program for Access to Credit in the modality guarantee of receivables (Peac-Maquininhas); Law No. 14,148/21, which set out the Emergency Program for Recovery of the Events Sector (PERSE), which aims at creating conditions to enable the events sector to mitigate losses arising from the public emergency, and the Guarantee Program for Critical Sectors (PGSC), to guarantee loan operations contracted up to 180 days after Law No. 14,148/21 came into effect; and BACEN Circular No. 3,990/20, and amendments made by BACEN Circular No. 3,992/20, which provides for repurchase agreements in foreign currency by the Central Bank of Brazil. We have identified the following impacts on results, as well as effects on estimates and critical judgments for the preparation of Consolidated Financial Statements: increase in loan and financing operations in 2020, especially for very small, small and middle-market companies, mainly driven by the measures adopted by authorities to mitigate the impacts of COVID-19, with the set-up of programs such as PESE, Pronampe, Peac-FGI and CGPE, the balance of which amounts to R$22,288 billion in June 2021. Through timely monitoring behavior standards and credit quality of clients, we have been able to keep the normal course of our operations despite adverse conditions, and helped clients in the sustainable search for their financial rebalancing; 4

(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, very small and small business clients. In March 2020, we set up the Program 60+, which, among other measures, allows a 60-day grace period for defaulting agreements, and the Travessia (Crossing) Program in mid-April. The Travessia program provides for the extension of grace periods between 120 and 180 days and terms of operations between 5 and 6 years, respectively, for individual and very small and small business clients, under better interest rate conditions; 0.9% increase in requests in the period for renegotiation and extension of terms for loan operations as the economic situation changed; allowance for loan losses in the amount of R$43,579 billion was impacted driven by the level of risk and default, due to the changes in the financial prospects of clients and the visible worsening of macroeconomic variables. To fully address the risk of our loan operations, we adopt the expected loss model for provisioning of operations since the moment they are granted. 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 our loan portfolio accounted for 221% from 255% in June 2020. Specifically, for the expected loss of operations that have not shown any signs of worsening so far (default or downgrading of the client's rating) provisioning was down 9.8% in the period. The credit risk governance has enabled us to promptly respond and monitor 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; the mark-to-market component of the securities portfolio was down to -1.3% in the first quarter of 2020, partially driven by rate fluctuations and high price volatility in the markets at the onset of the pandemic, influencing the measurement of items stated at fair value in their different levels. In the subsequent periods, the fluctuations in the mark-to-market component are not necessarily driven by the effects of the pandemic; over 2020, due to the COVID-19, the variable income market became instable, which led to the migration to fixed income instruments with liquidity. This movement resulted in increase in the Bank Deposit Certificates portfolio, which, however, over 2021, recorded a slight drop, leading to the normalization of the portfolio. Additionally, funding was also impacted, with increase in deposits. With the purpose of mitigating the system's liquidity risk, in 2020, the Central Bank of Brazil made available 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 billion were taken out during the term of these credit lines. 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, although it was not responsible for the generation of tax loss and social contribution loss carryforwards in Itaú Unibanco Holding S.A. In the period, the pandemic did not have a material impact on the recognition of deferred income tax and social contribution in Itaú Unibanco Holding S.A.; and increase in expenses on claims related to COVID-19 of R$219 million in the period, mainly related to life and credit life insurance. In-person customer service staff reduced and spacing between people in call centers was increased to reduce movement of people and possible 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 mainly working from home. It should be noted that, despite the aforementioned measures, we have maintained our operating activities. 5

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 Christmas bonus was advanced in full. Additionally, a process of communication and transparency with employees was established through emails, internal employee's portal and periodic videos prepared by our Chief Executive Officer communicating COVID-19-related news. At the branches, we have distributed masks to all employees involved in client service, implemented acrylic protective barriers and reviewed cleaning protocols. Our adaptation to the crisis is the result not only of technology investments, which allow for these virtual interactions, but also of investments in flexibility in the work environment, such as home working, communities integrated between different bank departments and new layouts in the administrative centers that promote employees' mobility. In 2020, we set up the initiative 'Todos pela Saúde' (All for Health) from the donation of R$1 billion, with the purpose of fighting 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, 'Todos pela Saúde' 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 innovating 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 worked together with competitors to combat hunger resulting from the pandemic and the economic crisis. Itaú Unibanco Holding contributed for the purchase and distribution of food staples. 6

10.3. Executive officers should comment on the material effects that may have been caused or are expected to be caused to the Issuer's financial statements and their results Introduction or disposal of operating segments Disclosure of results by segment The current business segments of Itaú Unibanco are described below: Retail Banking: The results of the Retail Banking segment derive from the offers of products and services to retail banking clients, high income clients and to very small and small companies. This segment comprises banking products and services provided to account holders and non-account holders. Products and services offered include: Personal credit, credit cards, payroll loans, vehicle financing, mortgage loans, insurance, pension plan and capitalization, and acquiring services, among others. Wholesale Banking: The results of the Wholesale Banking segment derive from: i) Itaú BBA's operations, the unit responsible for business with large companies and investment banking operations, ii) the results of our foreign units; and iii) products and services offered to middle-market companies, high net worth clients (Private Banking), and institutional clients. Trading & Institutional: The results of this segment derive from capital surplus, subordinated debt surplus and net balance of tax credits and debits. It also underlines the financial margin with the market, treasury operating costs, and equity in earnings of companies not associated with either of these segments. incorporation, acquisition or disposal of ownership interest XP Investimentos S.A. On May 11, 2017, we entered into a Share Purchase Agreement with XP Controle Participações S.A., G.A. Brasil IV Fundo de Investimento em Participações, and Dyna III Fundo de Investimento em Participações, among others, as sellers, to acquire 49.9% of the capital stock (corresponding to 30.06% of the common shares) of XP Investimentos S.A., a holding company that consolidates all the investments of the XP group, including XP Investimentos Corretora de Câmbio, Títulos e Valores Mobiliários S.A. In the first tranche, we contributed to a capital increase of R$600 million and acquired of XP Investimentos S.A.'s shares from the Sellers for R$5.7 billion, provided that such amounts are subject to contractual adjustments. The value attributed to 100% of the total capital stock of XP Investimentos S.A. (before the first tranche) was approximately R$12 billion. In August 2018, we closed the First Tranche and, together with some of the Sellers, entered into a shareholders' agreement which contains, among others, provisions with respect to our rights as a minority shareholder, including our right to appoint two out of the seven members of the Board of Directors of XP Investimentos S.A. On November 29, 2019, there was a corporate reorganization of XP Investimentos S.A., in which the shareholders of XP Investimentos S.A., including us, exchanged their shares of XP Investimentos S.A., incorporated in Brazil, for Class A common shares and Class B common shares of XP Inc., incorporated in the Cayman Islands, remaining with the percentages in the capital stock. Each Class A common share entitles its holder to one vote and each Class B common share entitles its holder to ten votes in all shareholders' resolutions of XP Inc. As a result of the contribution mentioned above, XP Inc. issued to us 792,861,320 Class A common shares and 223,595,962 Class B common shares, which represent 49.9% of the total capital of XP Inc. and 30.06% of its voting rights. XP Inc. became the sole shareholder of XP Investimentos S.A., owning 100% of its total and voting capital. Subsequently, on November 30, 2019, XP Inc. carried out a reverse stock split of one share for each four shares and, as a result, the number of shares held by us was adjusted to 198,215,329 Class A common shares and 55,898,991 Class B common shares. 7

In December 2019, XP Inc., a company in which we held 49.9% of capital stock, completed its initial primary offer (IPO) and listing on Nasdaq. We did not sell XP Inc. shares in such offer and immediately after the completion of the IPO, we now hold 46.05% of XP Inc.'s capital stock. Additionally, on November 29, 2019, the stockholders of XP Inc. entered into a shareholder agreement substantially similar to then existing shareholder agreement of XP Investimentos S.A. XP Inc. has a board of directors composed of 13 members, of which XP Controle A Participações S.A. appointed 7 members, we appointed 2 members, the General Atlantic (XP) Bermuda, LP (successor to GA Brasil IV Fundo de lnvestimento em Participações) appointed 1 member, and the 3 remaining members are independent directors. These independent directors are also members of the audit committee of XP lnc., which is composed of 3 members appointed as follows: we appointed 2 members, and XP Controle Participações SA appointed one member of the audit committee. On November 26, 2020, we announced that the Board of Directors approved the partial spin-off of the investment in XP INC for a new company (XPart S.A.). In December 2020 XP Inc. held a follow-on on Nasdaq, whereby we sold approximately 4.51% of XP Inc.'s capital. In that same offering, XP Inc. issued new shares, resulting in the dilution of our stake to 41% of its share capital. At the Extraordinary Stockholders' Meeting held on January 31, 2021, the corporate reorganization was decided in order to segregate the business line related to interest in XP Inc's capital to the new company that will be named XPart S.A., which will be constituted by a part of the investment currently owned by us at XP Inc. and cash worth R$10 million. The purpose of the segregation of the business line represented by our investment in XP Inc. into a new company (XPart SA) is that our stockholders will be entitled to equity interest in XPart SA in the same number and proportion of the shares they hold in Itaú Unibanco, as per the Material Fact disclosed on December 31, 2020. Therefore, the main benefit of the Transaction is value creation for our stockholders.The completion of this transaction was subject to regulatory approval to be obtained by our controlling shareholders. On May 28, 2021, the favorable approval of the Federal Reserve Board ('FED') was obtained, effective on May 31, 2021, the date from which the legal and accounting segregation of Itaú Unibanco Holding and XPart materialized. Consequently, XP Inc's capital stock held by XPart S.A. is now 40.52%, totaling R$9,371, as of December 31, 2020. On July 27, 2021, after the receipt of the approval of the operation by the Central Bank of Brazil, on that same date, XPart S.A. had its articles of association registered with the JUCESP (São Paulo state's Board of Trade). The shares issued by Itaú Unibanco, as well as the American Depositary Receipts (ADRs) will continue to be traded including the right to receive securities issued by XPart until the cut-off date (date of ex-right), which will be set and informed to the market as soon as possible. XP Inc. has expressed its interest in merging XPart and, accordingly, XP Inc. and Itaúsa announced to the market on May 28, 2021, that they have reached a final understanding regarding the merger. If the merger of XPart into XP Inc. is carried out, which will be resolved at the General Stockholders' Meetings of these companies at a date to be defined, the cut-off date mentioned above is planned to be after the closing of the trading session at the date of these General Stockholders' Meetings. As disclosed by Itaúsa and XP, should the said merger be approved by the stockholders of XP Inc. and XPart at the General Stockholders' Meetings of these companies, the stockholders of Itaú Unibanco Holding, who until the cut-off date will be entitled to receive securities issued by XPart, will receive: (a) as for the Company's controlling stockholders, IUPAR - Itaú Unibanco Participações S.A. and Itaúsa, and the holders of American Depositary Receipts (ADRs), Class A shares issued by XP Inc., and (b) as for the remaining stockholders, Level I sponsored Brazilian Depositary Receipts (BDRs), replacing the securities they would receive from XPart, which will not be listed on a stock exchange (because it will be dissolved after its merger into XP). Note that, 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, in accordance with paragraphs 3 and 4 of Article 223 of Law No. 6,404/76. 8

Itaú Unibanco Holding S.A. will keep its stockholders and the market informed of the progress and developments of this operation, including, as the case may be, details on the start of the period to exercise the right to reimbursement of shares by the stockholders dissenting from the merger resolved upon at the XPart's General Stockholders' Meeting, in accordance with paragraph 1 of Article 137 of Law 6,404/76. Lastly, conditioned on approval from the Central Bank of Brazil, pursuant to the purchase and sale agreement signed in 2017, we will purchase an additional stake of approximately 11.38% of XP Inc.'s capital stock, in 2022. The management and conduct of business of all companies within XP group, including XP Inc., remains independent, segregated and autonomous, preserving the same principles and values that are currently in force. XP Controle's partners will maintain control of the XP group, and the current directors, officers and executives of XP Investimentos S.A. and other subsidiaries will remain at the forefront of their respective businesses, in order to ensure that XP Investimentos S.A. will continue to act as an open and independent platform, offering a diversified range of proprietary and third party products to its clients, competing freely with other brokers and capital market distributors, including those controlled by us, without any restrictions or barriers. ZUP On October 31, 2019, we entered into a Share Purchase Agreement with ZUP LLC, and Bruno Cesar Pierobon, Gustavo Henrique Cunha Debs, Felupe Liguabue Almeida, Flavio Henrique Zago, among others ('Sellers'), for the acquisition of 100% of the voting share capital of Zup I.T. Serviços em Tecnologia e Inovação Ltda ('Zup') for R$575 million, and such amount is subject to contractual adjustments. Such acquisition will be implemented in three tranches over four years. In the first tranche, which closing occurred in March 31, 2020, Itaú acquired 52.96% of the total voting share capital of Zup (in fully diluted basis) for approximately R$293 million and will control the company. On the third year after the completion of the operation, Itaú will acquire an additional 19.6% stake, and on the fourth year Itaú will acquire the remaining stockholders' interest, holding, therefore, 100% of the voting share capital by 2024. This acquisition is linked to our digital transformation process. ZUP is a benchmark company in digital transformation, which has boosted our development of our IT systems. The operation and management of business affairs of Zup will continue to be totally independent and self-governing in relation to Itaú, preserving its current principles and values. IRB Initial Public Offering of IRB In July 2017, IRB-Brasil Resseguros S.A. (IRB) made an initial public offering of its common shares, which consisted of a public offering at a price of R$27.24 per share, and a secondary offering by its controlling shareholders of 63,960,000 registered book-entry common shares with no par value to (i) the public in Brazil, (ii) certain qualified institutional buyers in the United States (as defined in Rule 144A, or Rule 144A, under the U.S. Securities Act of 1933, as amended, or the Securities Act), and (iii) institutional and other investors elsewhere outside the United States and Brazil that are not U.S. persons (as defined in Regulation S under the Securities Act, or Regulation S). As a result of the initial public offering, Itaú Vida e Previdência S.A. sold 677,400 common shares, representing the total interest held by Itaú Vida e Previdência S.A. in IRB's capital stock, and Itaú Seguros S.A. sold 9,618,600 common shares, representing 3.1% of IRB's capital stock, reducing its interest in IRB to 11.64% of IRB's capital stock, remaining among the controlling block shareholders pursuant to the company's shareholders agreement. The proceeds received by Itaú Seguros S.A. and Itaú Vida e Previdência S.A. in the initial public offering totaled R$280,463,040.00. In accordance with Article 24 of CVM Normative Rule No. 400, the number of common shares initially offered could be increased by up to 9,594,000 common shares, representing up to 15% of the common shares initially offered, if the stabilizing agent (or any person acting on behalf of the stabilizing agent) exercises the over-allotment option. As a result of the full exercise of the over-allotment option by the stabilizing agent on August 28, 2017, Itaú Seguros S.A. became the owner of 11.14% of IRB's capital stock. 9

On July 10, 2019, the IRB conducted a secondary public offering of its common shares. With the sale of the entire participation held by the União and BB Seguros in IRB except in the case of the União, by Golden Share, the previously existing control block of the Company was dissolved, and its share capital was pulverized. c) Unusual events or operations In addition to the items underlined in item 10.3 b hereof, we highlight the following unusual events: In 2020: decrease in goodwill impairment and intangible assets of Itaú Corpbanca in the amount of R$(1,452) million, net of tax effects and interest of non-controlling stockholders; (ii) donations made for the Todos pela Saúde (All for Health) program in the total amount of R$(1,047) million; (iii) the mark-to-market effect of securities pledged as collateral of R$(1,031) million; (iv) the adjustment to market value of IRB shares in the amount of R$379 million; and (v) the provision for restructuring in the amount of R$(220) million, mainly related to closing branches, returning administrative buildings, among others.

Financial margin with clients: the lower-than-expected consolidated growth was mainly driven by the foreign exchange variation in our Latin American operations. Cost of credit: the higher-than-expected consolidated level was mainly due to a higher increase in loan portfolio in Brazil and higher-than-expected levels of provision for the Latin America portfolio, driven by macroeconomic uncertainties in Chile in the fourth quarter of 2019. Commissions and fees and result from insurance operations: the higher-than-expected consolidated growth and in Brazil was mainly driven by higher revenues from economic and financial advisory, brokerage and fund management services. Non-interest expenses: the lower-than-expected consolidated growth and in Brazil was due to the efficient cost management. Projections for fiscal year 2018 Includes units abroad ex-Latin America; (2) Includes financial guarantees provided and corporate securities;(3) Includes Result from Loan Losses, Impairment and Discounts Granted; (4) Commissions and Fees (+) Income from Insurance, Pension Plan and Premium Bonds Operations (-) Expenses for Claims (-) Insurance, Pension Plan and Premium Bonds Selling Expenses. 15

Explanation for any difference in projections: Financial margin with the market: the higher-than-expected consolidated growth was mainly driven by our results in Latin America. Commissions and fees and result from insurance operations: the lower-than-expected growth in Brazil was mainly driven by the lower-than-expected level of economic activity and a fiercer competitive environment. Non-interest expenses: the higher-than-expected consolidated growth was mainly driven by the foreign exchange variation in our Latin America operations. with respect to the current period guidance, state whether the projections are still valid on the date the form is submitted and, when applicable, explain why they were abandoned or replaced The table below indicates the revised guidance for 2021 Managerial Result. Includes units abroad ex-Latin America; (2) Includes financial guarantees provided and corporate securities;(3) Includes Result from Loan Losses, Impairment and Discounts Granted; (4) Commissions and Fees (+) Income from Insurance, Pension Plan and Premium Bonds Operations (-) Expenses for Claims (-) Insurance, Pension Plan and Premium Bonds Selling Expenses. Explanation for the need of guidance revision: Total loan portfolio: expectation of higher portfolio growth in Brazil in retail and wholesale. The drivers for that are the strong recovery of economic activity in Brazil and the greater demand of credit products for individuals, especially mortgage, and for corporate as a consequence of capital market conditions. The guidance revision for the consolidated figures reflects the Brazilian business performance. Financial margin with the market: expectation of better result due to greater performance of our trading desk in Brazil and Latin America, the better accrual in structural positions as a result of our treasury management and the opening of the yield curve, and changes in macroeconomic conditions. Cost of credit: the expectation of a lower cost of credit in the year is based on the best economic conditions in Brazil and good credit quality even with higher growth of the portfolio. We continuously 16

carry out risk revaluations of our portfolio and the level of provisioning reflects the dynamics of portfolio growth and the evolution of our customers' credit risk. The guidance revision for the consolidated figures reflects business conditions in Brazil. The guidance was unchanged for financial margin with clients, commissions and fees and result from insurance operations, non-interest expenses and effective income and social contribution tax rate. 17

15.7. Describe the main corporate operations carried out in the group that have a significant effect for the issuer, such as takeovers, mergers, spin-offs, mergers of shares, sales and acquisitions of ownership interest, acquisitions and disposals of important assets, indicating when the issuer or any of its subsidiaries or affiliates is involved: event; main business conditions; companies involved; effects arising from the transaction on the corporate structure, particularly on the ownership interest of the issuer's parent company, stockholders with more than 5% of the capital, and management members; corporate structure before and after the transaction; mechanisms adopted to ensure equitable treatment among stockholders For purposes of this item, we adopted as materiality criterion operations involving amounts higher than R$772.6 million, which accounts for 0.5% of Itaú Unibanco Holding's stockholders' equity under IFRS (R$154,525 million on December 31, 2020). 2020 XP Inc. Event Acquisition of shareholding in XP Inc., a company incorporated in the Cayman Islands and listed on Nasdaq. XP Inc. owns 100% of XP Investimentos S.A. ('XP Investimentos'), which, in turn, consolidates all investments of XP Group ('XP Group'), including XP Investmentos Corretora de Cmbio, Títulos e Valores Mobiliários S.A. ('XP Corretora'). Main business conditions On May 11, 2017, we entered into a Share Purchase Agreement with XP Controle Participações S.A., G.A. Brasil IV Fundo de Investimento em Participações, and Dyna III Fundo de Investimento em Participações, among others, as sellers, to acquire 49.9% of total capital stock (corresponding to 30.06% of common shares) of XP Investimentos S.A., a holding company that consolidates all the investments of the XP group, including XP Investimentos Corretora de Câmbio, Títulos e Valores Mobiliários S.A. In the first tranche ('First Tranche'), we contributed to a capital increase of R$600 million and acquired shares issued by XP Investimentos S.A. held by Sellers for R$5.7 billion, with such amounts subject to contractual adjustments. The value attributed to 100% of total capital stock of XP Investimentos S.A. (before the first tranche) was approximately R$12 billion. In August 2018, we closed the First Tranche and Itaú Unibanco S.A., together with some of the Sellers, entered into a shareholder agreement which contains, among others, provisions with respect to Itaú Unibanco S.A.'s rights as a minority shareholder of XP Investimentos S.A., including its right to appoint two out of the seven members of the Board of Directors of XP Investimentos S.A. On November 29, 2019, there was a corporate restructuring of XP Investimentos S.A., where the stockholders of XP Investimentos S.A., including Itaú Unibanco, exchanged all their shares in XP Investimentos S.A., a company incorporated in Brazil, for Class A common shares and Class B common shares in XP Inc., a company incorporated in the Cayman Islands, remaining with the percentages in the capital stock. Each Class A common share entitles its holder to one vote and each Class B common share entitles its holder to ten votes in all stockholders' resolutions of XP Inc. As a result of the contribution mentioned above, XP Inc. issued to Itaú Unibanco 792,861,320 Class A common shares and 223,595,962 Class B 63

common shares, which represent 49.9% of total capital of XP Inc. and 30.06% of its voting capital. XP Inc. became the sole shareholder of XP Investimentos S.A., owning 100% of its total and voting capital. Subsequently, on November 30, 2019, XP Inc. carried out a reverse stock split of one share for each four shares and, as a result, the number of shares held by Itaú Unibanco was adjusted to 198,215,329 Class A common shares and 55,898,991 Class B common shares. In December 2019, XP Inc., a company in which we held 49.9% of capital stock, completed its initial primary offer (IPO) and listing on Nasdaq. We did not sell XP Inc. shares in such offer and immediately after the completion of the IPO, we now hold 46.05% of XP Inc.'s capital stock. Additionally, on November 29, 2019, the stockholders of XP Inc. entered into a shareholder agreement substantially similar to then existing shareholder agreement of XP Investimentos S.A. XP Inc. has a board of directors composed of 13 members, of which XP Controle A Participações S.A. appointed 7 members, we appointed 2 members, the General Atlantic (XP) Bermuda, LP (successor to GA Brasil IV Fundo de lnvestimento em Participações) appointed 1 member, and the 3 remaining members are independent directors. These independent directors are also members of the audit committee of XP lnc., which is composed of 3 members appointed as follows: we appointed 2 members, and XP Controle Participações SA appointed one member of the audit committee. On November 26, 2020, we announced that our Board of Directors had approved the partial spin-off of the investment in XP lnc. to be transferred to a new company (XPart S.A.). In December 2020, XP Inc. carried out a public stock offer (follow-on) on Nasdaq, through which we sold approximately 4.51% of capital in XP Inc. In that same offer, XP Inc. issued new shares, which resulted in the dilution of our interest to 41% of its capital stock. The Extraordinary General Stockholders' Meeting (ESM) held on January 31, 2021 resolved on the corporate restructuring aimed at segregating the business line related to the interest in XP lnc's capital to a new company to be named XPart S.A., which will be constituted by a part of the investment currently owned by us at XP Inc. and cash worth R$10 million. The purpose of the segregation of the business line represented by our investment in XP Inc. into a new company (XPart SA) is that our stockholders will be entitled to equity interest in XPart SA in the same number and proportion of the shares they hold in Itaú Unibanco, as per the Material Fact disclosed on December 31, 2020. Therefore, the main benefit of the Transaction is value creation for our stockholders. The completion of this transaction was subject to regulatory approval to be obtained by our controlling shareholders. On May 28, 2021, the favorable approval of the Federal Reserve Board ('FED') was obtained, effective on May 31, 2021, the date from which the legal and accounting segregation of Itaú Unibanco Holding and XPart materialized. Consequently, XP Inc's capital held by XPart S.A. is now 40.52%, totaling R$9,371, as of December 31, 2020. On July 27, 2021, after the receipt of the approval of the operation by the Central Bank of Brazil, on that same date, XPart S.A. had its articles of association registered with the JUCESP (São Paulo state's Board of Trade). The shares issued by Itaú Unibanco, as well as the American Depositary Receipts (ADRs) will continue to be traded including the right to receive securities issued by XPart until the cut-off date (date of ex-right), which will be set and informed to the market as soon as possible. XP Inc. has expressed its interest in merging XPart and, accordingly, XP Inc. and Itaúsa announced to the market on May 28, 2021, that they have reached a final understanding regarding the merger. If the merger of XPart into XP Inc. is carried out, which will be resolved at the General Stockholders' Meetings of these companies at a date to be defined, the cut-off date mentioned above is planned to be after the closing of the trading session at the date of these General Stockholders' Meetings. 64

As disclosed by Itaúsa and XP Inc., should the said merger be approved by the stockholders of XP Inc. and XPart at the General Stockholders' Meetings of these companies, the stockholders of Itaú Unibanco Holding, who until the cut-off date will be entitled to receive securities issued by XPart, will receive: (a) as for the Company's controlling stockholders, IUPAR - Itaú Unibanco Participações S.A. and Itaúsa, and the holders of American Depositary Receipts (ADRs), Class A shares issued by XP Inc., and (b) as for the remaining stockholders, Level I sponsored Brazilian Depositary Receipts (BDRs), replacing the securities they would receive from XPart, which will not be listed on a stock exchange (because it will be dissolved after its merger into XP). Note that, 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, in accordance with paragraphs 3 and 4 of Article 223 of Law No. 6,404/76. Itaú Unibanco Holding S.A. will keep its stockholders and the market informed of the progress and developments of this operation, including, as the case may be, details on the start of the period to exercise the right to reimbursement of shares by the stockholders dissenting from the merger resolved upon at the XPart's General Stockholders' Meeting, in accordance with paragraph 1 of Article 137 of Law 6,404/76. Lastly, conditioned on approval from the Central Bank of Brazil, pursuant to the purchase and sale agreement signed in 2017, we will purchase an additional stake of approximately 11.38% of XP Inc.'s capital stock, considering the number of shares in XP Inc. as of December 31, 2020. The management and conduct of business of all companies of the XP group, including XP Inc., will remain independent, segregated and autonomous, preserving the same principles and values in force before the First Tranche. XP Controle's partners will keep on controlling the XP group, and current directors, officers and executives of XP Investimentos S.A. and other subsidiaries will remain at the forefront of their respective business, in order to ensure that XP Investimentos S.A. continue to operate as an open and independent platform, offering a diversified range of proprietary and third party products to its clients, competing freely with other capital market brokers and distributors, including those controlled by Itaú Unibanco conglomerate, without any restrictions or barriers. Companies involved ITB Holding Brasil Participações Ltda., Itaú Unibanco S.A., XP Inc., XP Investimentos S.A., General Atlantic (XP) Bermuda, LP (successor of G.A. Brasil IV Fundo de Investimento em Participações), Dyna III Fundo de Investimento em Participações Multiestratégia, XP Controle Participações S.A., and XPart S.A. Effects arising from the transaction on the corporate structure, particularly on the ownership interest of the issuer's parent company, stockholders holding more than 5% of the capital, and management members There will not be any change in the Issuer's corporate structure. Corporate structure before and after the transaction There will not be any change in the Issuer's corporate structure. Mechanisms adopted to ensure the equitable treatment among stockholders Not applicable, since it has had no effects on the equitable treatment of the Issuer's stockholders. 65

17.5. Other significant information Item 17.1 - Information - Capital On February 22, 2018, the Board of Directors resolved to cancel 14,424,206 common book-entry shares of its own issue and held as treasury stock, without reducing capital, acquired by the Company by means of the Share Buyback Program authorized by the Board of Directors on December 15, 2017. As a result of this cancellation, the capital amounting to R$97,148,000,000.00 now comprises 6,536,090,232 book-entry shares with no par value, of which 3,305,526,906 are common shares and 3,230,563,326 are preferred shares, and the resulting changes in the Bylaws were resolved upon in the General Stockholders' Meeting. On January 31, 2021, the Board of Directors resolved to transfer the spun off portion to contribute to the capital stock of XPart S.A. consequently reducing the Company's capital stock by six billion, four hundred nineteen million Brazilian reais (R$6,419,000,000.00), totaling ninety billion, seven hundred twenty-nine million Brazilian reais (R$ 90,729,000,000.00) from ninety-seven billion, one hundred forty-eight million Brazilian reais (R$ 97,148,000,000.00) without cancelling shares. On May 28, 2021, the favorable opinion of the FED was obtained, effective on May 31, 2021. This transaction was approved by the Central Bank of Brazil on July 26, 2021. Item 17.3 - Stock split, reverse stock split and bonus shares I - Stock split - July 27, 2018 At the Extraordinary General Stockholders' Meeting held on July 27, 2018, our stockholders approved the split in 50% of the then current 6,536,090,232 book-entry shares with no par value that comprise the capital stock, of which 3,305,526,906 are common and 3,230,563,326 are preferred shares. Therefore, the stock split was carried out by issuing 3,268,045,116 new shares, of which 1,652,763,453 are common and 1,615,281,663 are preferred shares, which were assigned free of charge to stockholders as a stock split. Accordingly, stockholders received one (1) new share for each two (2) shares of the same type they own, and treasury shares were also split. The dividend distribution policy will not be changed as a result of this approval. The Stockholders' Meeting also approved an increase in the authorized capital limit, proportionally to the 50% stock split, so that the Company is authorized to increase capital stock in accordance with the resolution taken by the Board of Directors, irrespective of a statutory reform, up to the limit of thirteen billion, one hundred and seventy-six million, nine hundred thousand (13,176,900,000) shares, of which six billion, five hundred and eighty-eight million, four hundred and fifty thousand (6,588,450,000) are common and six billion, five hundred eighty-eight million, four hundred fifty thousand (6,588,450,000) are preferred shares.
