Risk and Capital Management – Pillar 3 Objective This document presents Itaú Unibanco Holding S.A. (Itaú Unibanco) information required by the Central Bank of Brazil (BACEN) through Circular 3,930 and subsequent amendments, which addresses the disclosure of information on risks and capital management, the comparison between accounting and prudential information, the liquidity and market risk indicators, the calculation of risk-weighted assets (RWA), the calculation of the Total Capital (“Patrimônio de Referência”—PR), and the compensation of management members1. The referred Circular brought several amendments in the disclosure format of the Pillar 3 information, besides changes in the scope and frequency of the information disclosed. All these amendments, implemented by the Central Bank, aim the convergence of the Brazilian financial regulation to the recommendations of the Basel Committee, seeking to harmonize the information disclosed by financial institutions at an international level, and taking into account the structural conditions of the Brazilian economy. The disclosure policy of the Risk and Capital Management Report presents the guidelines and responsibilities of the areas involved in its preparation, as well as the description of the information that must be disclosed and the integrity endorsement and approval governance, as established by the article 56 of the Resolution nº. 4,557. Key indicators Itaú Unibanco’s risk and capital management focuses on maintaining the institution in line with the risk strategy approved by the Board of Directors. The key indicators based on the Prudential Consolidation, on December 31, 2020, are summarized below. Common Equity Tier I Ratio Tier I Ratio Total Capital Ratio 11.5% 13.2% 14.5% September 30, 2020: 10.7% September 30, 2020: 12.4% September 30, 2020: 13.7% Common Equity Tier I Tier I Total Capital R$ 119,960 million R$ 137,157 million R$ 151,244 million September 30, 2020: R$ 113,910 million September 30, 2020: R$ 132,272 million September 30, 2020: R$ 146,894 million RWA R$ 1,042,207 million September 30, 2020: R$ 1,068,739 million 1 Itaú Unibanco

Risk and Capital Management – Pillar 3 Prudential Metrics and Risk Management Itaú Unibanco invests in robust and company-wide risk management processes to serve as a basis for its strategic decisions intended to ensure business sustainability. The key prudential metrics related to regulatory capital and information on the bank’s integrated risk management are presented below. KM1: Key metrics at consolidated level In order to ensure the soundness of Itaú Unibanco and the availability of capital to support business growth, Itaú Unibanco maintains capital levels above the minimum requirements, as demonstrated by the Common Equity Tier I, Additional Tier I Capital and Total CapitaI ratios. On December 31, 2020, the Total Capital (PR) reached R$ 151,244 million, R$ 137,157 million of Tier I and R$ 14,087 million of Tier II.

(2) The countercyclical capital buffer is fixed by the Financial Stability Committee (Comef) based on discussions about the pace of credit expansion (BACEN Communication No. 36,418/20), and currently is set to zero. Should the requirement increase, the new percentage takes effect twelve months after the announcement. (3) The BACEN rules establish Capital Buffers, that corresponds to the sum of the Conservation, Contracyclical and Systemic requirements, as defined in CMN Resolution 4,193. The Total Capital Ratio reached 14.5% on December 31, 2020, increasing 80 basis points when compared to September 30, 2020 mainly due to net income in the period, including the result from the sale of shares issued by XP Inc.and a decrease in the Credit Risk Weighted Assets. Besides, Itaú Unibanco has a R$ 67,867 million capital excess in relation to its minimum required Total Capital. It corresponds to 650 basis points above the minimum requirement (8%) and higher than the Capital Buffer requirement of 225 basis points (R$ 23,450 million). Considering the Capital Buffers, the capital excess would be 425 basis points. In December 2020, Itaú Unibanco Holding issued R$ 2.1 billion, in Subordinated Financial Notes, which have a repurchase option as from 2025. These subordinated notes are subject to approval by the Central Bank of Brazil 2 Itaú Unibanco

Risk and Capital Management – Pillar 3 for the composition of Itaú Unibanco’s Tier II Capital, with an estimated increase of 20 basis points in its Total Capital Ratio. The fixed assets ratio shows the commitment percentage of adjusted Referential Equity with adjusted permanent assets. Itaú Unibanco falls within the maximum limit of 50% of adjusted PR, established by BACEN. On December 31, 2020, fixed assets ratio reached 24.0%, showing a surplus of R$ 39,274 million. OVA – Bank risk management approach Scope and main characteristics of risk management To undertake and manage risks is one of the activities of Itaú Unibanco. For this reason, the institution must have clearly established risk management objectives. In this context, the risk appetite defines the nature and the level of risks acceptable for the institution, while the risk culture guides the attitudes required to manage them. Itaú Unibanco invests in robust risk management processes, that are the basis for its strategic decisions to ensure business sustainability and maximize shareholder value creation. These processes are in line with the guidelines of the Board of Directors and Executives who, through corporate bodies, define the institution’s global objectives, which are then translated into targets and thresholds for the business units that manage risks. Control and capital management units, in turn, support Itaú Unibanco’s management through the processes of analysis and monitoring of capital and risk. The principles that provide the risk management and the risk appetite foundations, as well as guidelines regarding the actions taken by Itaú Unibanco’s employees in their daily routines are as follows: • Sustainability and customer satisfaction: the vision of Itaú Unibanco is to be a leading bank in sustainable performance and customer satisfaction. For this reason, the institution is concerned about creating shared values for employees, customers, shareholders and society to ensure the longevity of the business. Itaú Unibanco is concerned about doing business that is good for customers and for the institution; • Risk culture: the institution’s risk culture goes beyond policies, procedures and processes. It strengths the individual and collective responsibility of all employees to manage and mitigate risks consciously, respecting the ethic way of doing business. The risk culture is described in the item “Risk Culture”; • Risk Pricing: Itaú Unibanco 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: the institution has low appetite for volatility in its results. Accordingly, it operates with a diversified base of customers, products and business, seeking risk diversification and giving priority to low-risk transactions; • Operational excellence: Itaú Unibanco intends to provide agility, as well as a robust and stable infrastructure, in order to offer high quality services; • Ethics and respect for regulations: at Itaú Unibanco, ethics is non-negotiable. For this reason, the institution promotes an institutional environment of integrity, educating its employees to cultivate ethical relationships and businesses, as well as respecting the norms, and therefore looking after the institution’s reputation. Since August, 2017, the Resolution CMN 4,557 came into force, which established the structure of risk and capital management. The resolution highlights are the implementation of a continuous and integrated risk management framework; the requirements for the definition of the Risk Appetite Statement (RAS) and the stress test program; the establishment of a Risk Committee; the indication, before BACEN, of the Chief Risk Officer (CRO); and the CRO’s roles, responsibilities and independence requirements. Risk and Capital Governance The Board of Directors is the main body responsible for establishing the guidelines, policies and authority levels regarding risk and capital management. In turn, the Risk and Capital Management Committee (CGRC) provides support to the Board of Directors in the performance of their duties relating to risk and capital management. At 3 Itaú Unibanco

Risk and Capital Management – Pillar 3 the executive level, corporate bodies headed by Itaú Unibanco’s Chief Executive Officer (CEO) are established to manage risks and capital. Their decisions are overseen by the CGRC. Additionally, the institution has corporate bodies that perform delegated duties in the risk and capital management, and that are headed by the Vice-President of the Risk and Finance Area (ARF). To support this structure, ARF is structured with specialized departments. The objective is to provide independent and centralized management of the institution’s risks and capital, and to ensure the accordance with the established rules and procedures. Itaú Unibanco’s risk management organizational structure complies with Brazilian and international regulations in place and is aligned with the market’s best practices. Responsibilities for risk management at Itaú Unibanco are structured according to the concept of three lines of defense, namely: • in the first line of defense, the business and corporate support areas manage risks they give rise to, by identifying, assessing, controlling and reporting such risks; • in the second line of defense, an independent unit provides central control, so as to ensure that Itaú Unibanco’s risk is managed according to the risk appetite and established policies and procedures. This centralized control provides the Board and executives with a global overview of Itaú Unibanco’s exposure, to ensure correct and timely corporate decisions; • in the third line of defense, internal audit provides an independent assessment of the institution’s activities, so that senior management can see that controls are adequate, risk management is effective and institutional standards and regulatory requirements are being complied with. Itaú Unibanco uses robust automated systems for full compliance with capital regulations, as well as for measuring risks in accordance with the regulatory determinations and models in place. It also monitors adherence to the qualitative and quantitative regulators’ minimum capital and risk management requirements. Risk Appetite Itaú Unibanco has a risk appetite policy, which was established and approved by the Board of Directors and guides the institution’s business strategy. The bank’s risk appetite is grounded on the following declaration of the Board of Directors: “We are a universal bank, operating predominantly in Latin America. Supported by our risk culture, we operate based on rigorous ethical and regulatory compliance standards, seeking high and growing results, with low volatility, by means of the long-lasting relationship with clients, correctly pricing risks, well-distributed fund-raising and proper use of capital.” Based on this declaration, the bank established five dimensions, each of which comprising a set of metrics associated with the key risks involved, combining complementary measurements and seeking a comprehensive view of its exposure: • Capitalization: establishes that Itaú Unibanco should have sufficient capital to protect itself against a serious recession or stress events without the need to adjust its capital structure under adverse circumstances. It is monitored by following up the bank’s capital ratios, in usual or stress situations, and the institution’s debt issue ratings. • Liquidity: establishes that the institution’s liquidity should be able to support long stress periods. It is monitored by following up on liquidity ratios. • Composition of results: establishes that business will mainly focus on Latin America, where Itaú Unibanco will have a diversified range of customers and products, with low appetite for results volatility and high risk. This dimension includes business and profitability, as well as market and credit risks aspects. The metrics monitored by the bank seek to ensure, by means of exposure concentration limits such as, for example, industry sectors, quality of counterparties, countries and geographic regions and risk factors, a suitable composition of the bank’s portfolios, aiming at low volatility of results and business sustainability. • Operational risk: focuses on controlling operational risk events that may adversely impact the bank’s business strategy and operations. This control is carried out by monitoring key operational risk events and incurred losses. 4 Itaú Unibanco

Risk and Capital Management – Pillar 3 • Reputation: deals with risks that may impact brand value and the institution’s reputation before its customers, employees, regulators, investors and the general public. In this dimension, risks are monitored by following up on customers’ satisfaction or dissatisfaction, media exposure and observation of the institution’s conduct. The Board of Directors is responsible for approving risk appetite guidelines and limits, performing its activities with the support of the Risk and Capital Management Committee (CGRC) and the Chief Risk Officer (CRO). Metrics are regularly monitored and must comply with the limits defined. The monitoring is reported to the risk commissions and to the Board of Directors, guiding the use of preventive measures to ensure that exposures are within the limits provided and in line with the bank’s strategy. Risk Culture Aiming at strengthening its values and aligning the behavior of its employees with risk management guidelines, the institution adopts several initiatives to disseminate and strengthen its Risk Culture, which is based on four principles: conscious risk taking, discussions and actions on the institution’s risks, and each and everyone’s responsibility for risk management. Besides the risk management policies, procedures and processes, the institution promotes its Risk Culture by emphasizing a behavior that helps people of all company levels to undertake and manage risks in a conscious way. By disseminating these principles, the institution fosters the understanding and the open discussion about risks, so that they are kept within the risk appetite levels established and each employee individually, regardless of their position, area or duties, may also assume responsibility for managing the risks of the business. Itaú Unibanco also makes some channels available for communication of operating failures, internal or external fraud, conflicts at the workplace, or cases that may result in inconveniences and/or losses for the institution or its customers. All employees or third parties are responsible for informing any problems immediately, as soon as they become aware of the situation. Stress Testing The stress test is a process of simulating extreme economic and market conditions on Itaú Unibanco’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 and approved by the Board of Directors. Projections for the macroeconomic variables (such as GDP, the basic interest rate 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 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 (Internal Capital Adequacy Process), 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. 5 Itaú Unibanco

Risk and Capital Management – Pillar 3 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. Recovery Plan In response to the latest international crises, the Central Bank issued the Resolution No. 4,502, which requires the development of a Recovery Plan for the financial institutions that are classified in the Segment 1, with a total exposure of more than 10% of Gross Domestic Product (GDP). This plan aims to reestablish adequate levels of capital and liquidity, above the regulatory requirements, through appropriate strategies in the event of severe stress shocks of a systemic or idiosyncratic nature. Accordingly, each institution would be able to preserve its financial feasibility and, at the same time, mitigate the impact on the National Financial System. Itaú Unibanco has a Recovery Plan that contemplates the entire conglomerate, including foreign subsidiaries, and contains the description of the following items: I. Critical functions rendered by Itaú Unibanco to the market, activities that, if abruptly interrupted, could impact the National Financial System (SFN) and the functioning of the real economy; II. Institution’s essential services: activities, operations or services which discontinuity could compromise the bank’s viability; III. Monthly monitoring program, establishing critical levels for a set of indicators, with a view to risk monitoring and eventual trigger for the execution of the Recovery Plan; IV. Stress scenarios, contemplating events that may threaten the business continuity and the viability of the institution, including reverse tests, which seek to identify remote risk scenarios, contributing to an increase of the management sensitivity; V. Recovery strategies in response to different stress scenarios, including the main risks and barriers, as well as the mitigators of the latter and the procedures for the operationalization of each strategy; VI. Communication plan with stakeholders, seeking its timely execution with the market, regulators and other stakeholders; VII. Governance mechanisms necessary for the coordination and execution of the Recovery Plan, such as the definition of the director responsible for the exercise at Itaú Unibanco. This plan is reviewed annually and is subjected to the approval of the Board of Directors. With this practice, Itaú Unibanco has been able to continuously demonstrate, since its first edition in 2017, that even in severe scenarios, with remote probability of occurrence, it has strategies capable of generating sufficient resources to ensure the sustainable maintenance of critical activities and essential services, without losses to customers, to the financial system and to other participants in the markets in which it operates. Itaú Unibanco ensures the exercise maintenance to guarantee that strategies remain up-to-date and viable in the face of organizational, competitive or systemic changes. Capital Adequacy Assessment For its capital adequacy assessment process, the annual Itaú Unibanco’s procedure is as follows: • Identification of material risks and assessment of the need for additional capital; • Preparation of the capital plan, both in normality and stress situations; • Internal assessment of capital adequacy; • Structuring of capital contingency and recovery plans; • Preparation of management and regulatory reports. 6 Itaú Unibanco

Risk and Capital Management – Pillar 3 By adopting a prospective stance regarding capital management, Itaú Unibanco implemented its capital management structure and its ICAAP in order to comply with National Monetary Council (CMN) Resolution 4,557, BACEN Circular 3,846 and BACEN Circular Letter 3,907. The result of the last ICAAP, which includes stress tests – dated as of December 2019 – showed that, in addition to having enough capital to face all material risks, Itaú Unibanco has a significant buffer, thus ensuring the soundness of its equity position. Capital Adequacy Itaú Unibanco, through the ICAAP process, assesses the adequacy of its capital to face the incurred risks, composed by regulatory capital for credit, market and operational risks and by the necessary capital to face other risks. In order to ensure the soundness and the availability of Itaú Unibanco’s capital to support business growth, the Total Capital levels were maintained above the minimum requirements. OV1 – Overview of risk-weighted assets (RWA) According to CMN Resolution 4,193 and subsequent amendments, for assessing the minimum capital requirements, the RWA must be calculated by adding the following risk exposures: RWA = RWACPAD + RWAMINT + RWAOPAD • RWACPAD = portion related to exposures to credit risk, calculated using standardized approach; • RWAMINT = portion related to the market risk capital requirement, made up of the maximum between the internal model and 80% of the standardized model, and regulated by BACEN Circulars 3,646 and 3,674; • RWAOPAD = portion related to the operational risk capital requirement, calculated using standardized approach. RWA Minimum capital requirements R$ million 12/31/2020 09/30/2020 12/31/2020 Credit Risk: standardized approach 921,934 948,063 73,755 Credit risk (excluding counterparty credit risk) 778,153 776,410 62,252 Counterparty credit risk (CCR) 45,674 56,801 3,654 Of which: standardized approach for counterparty credit risk (SA-CCR) 27,119 35,054 2,170 Of which: Current Exposure Method approach (CEM) — — - Of which: other CCR 18,555 21,747 1,484 Credit valuation adjustment (CVA) 5,960 9,408 477 Equity investments in funds—look-through approach 4,897 5,564 392 Equity investments in funds—mandate-based approach 623 286 50 Equity investments in funds—fall-back approach 716 134 57 Securitisation exposures—standardized approach 1,506 — 121 Amounts below the thresholds for deduction 84,405 99,460 6,752 Market risk 27,481 27,884 2,198 Of which: standardized approach 34,351 34,855 2,748 Of which: internal models approach (IMA) 22,362 24,314 1,789 Operational risk 92,792 92,792 7,423 Total 1,042,207 1,068,739 83,377 The decrease of R$ 26,532 million in the Risk-Weighted Assets (RWA) was mainly driven by an decrease in the Credit Risk Weighted Assets (RWACPAD) due to the foreign exchange variation during the period. The reduction in the Market Risk-Weighted Assets (RWAMINT) was driven by a variation in the Interest Rate Risk. 7 Itaú Unibanco

Risk and Capital Management – Pillar 3 Links between financial statements and regulatory exposures LIA: Explanations of differences between accounting and regulatory exposure amounts The main difference between the accounting carrying value and the amounts considered for regulatory purposes is the non-consolidation of non-financial companies (especially Insurance, Pension Plan and Capitalization companies) in the regulatory consolidated, a difference that also impacts the elimination of related parties transactions. Within the regulatory scope, the procedures for assessing the need for prudent valuation adjustments (PVAs) arising from the pricing of financial instruments, as well as the description of the systems and controls used to ensure its reliability are described below. The pricing methodology for the financial instruments subject to Resolution No. 4,277, of October 31st, 2013, conducted by an independent area from the business areas, considers, in addition to benchmarks, the risks listed in the closeout uncertainty, market concentration, early termination, model risk, investing and funding costs, unearned credit spread and others. The fair value measurement at Itaú Unibanco follows the principles enclosed in the main regulatory bodies, such as CVM and BACEN. The institution follows the best practices in terms of pricing policies, procedures and methodologies and is committed to secure the pricing of financial instruments in its balance sheet with prices quoted and disclosed by the market, and in the impossibility of doing so, expends its best efforts to estimate which would be the fair price at which financial assets would be effectively traded, maximizing the use of relevant observable data and, under specific conditions, these instruments can be valued on a model basis. In all of these situations, the organization has control over its pricing methods and model risk management. The process of independent price verification (IPV) follows the guidelines included in Resolution No. 4,277, with daily verification of prices and market inputs, which is performed by a team independent from the pricing team. This process is also subject to an independent evaluation by the internal control, internal audit and external audit teams. The institution has a hybrid model for assessing the need for prudent valuation adjustments with two components. The first component is a timely assessment model that assesses new products, operations and risk factors traded and verifies the compliance and liability with any components of the existing prudent valuation adjustments. The second is a periodic assessment that aims to analyze the existing prudent valuation adjustments in relation to adequate pricing.

Risk and Capital Management – Pillar 3 Leverage Ratio The Leverage Ratio is defined as the ratio between Tier I Capital and Total Exposure, calculated according to BACEN Circular 3,748. The ratio is intended to be a simple measure of non-risk-sensitive leverage, and so it does not take into account risk weights or risk mitigation. As required by BACEN Circular Letter 3,706, Itaú Unibanco monthly reports to BACEN the Leverage Ratio, which minimum requirement is of 3%. The following information is based on the methodology and standard format introduced by BACEN Circular 3,748.

Risk and Capital Management – Pillar 3 Liquidity Ratios LIQA: Liquidity Risk Management Information Framework and Treatment Liquidity risk is defined as the likelihood of the institution not being able to effectively honor its expected and unexpected obligations, current and future, including those from guarantees commitment, without affecting its daily operations or incurring in significant losses. In line with the fundraising strategy, Itaú Unibanco has diversified and stable sources of funding available, monitored through concentration and maturity indicators, in order to mitigate liquidity risks, in accordance with the institution’s risk appetite. The governance of the liquidity risk management is based on advisory boards, subordinated to the Board of Directors or the executive structure of Itaú Unibanco. Such boards establish the institution’s risk appetites, define the limits related to the liquidity control and monitor the liquidity indicators. The control of the liquidity risk is carried out by an area that is independent of the business areas, responsible for defining the composition of the reserve, estimating the cash flow and the exposure to liquidity risk in different time horizons and monitoring short and long term liquidity indicators (LCR and NSFR respectively). In addition, it proposes minimum limits to absorb losses in stress scenarios for each country where Itaú Unibanco operates and reports any non-compliance to the competent authorities. All activities are subject to verification by the independent validation, internal controls and audit departments. Additionally, and pursuant to the requirements of Resolution 4,557, BACEN Circular 3,749 and Circular 3,869, the Liquidity Risk Statement (DRL—LCR) and the Long Term Liquidity Statement (DLP—NSFR) are monthly sent to BACEN. Finally, the following items are periodically prepared and submitted to senior management for monitoring and decision support: • Stress of liquidity indicators based on macroeconomic scenarios, simulation of reverse stress based on risk appetite, and projection of the main liquidity indicators to support decisions; • Contingency and recovery plans for crisis situations, with actions that provide for a gradation according to the level of criticality determined by the easiness of implementation, taking into account the characteristics of the local market in which it operates, seeking a rapid restoration of liquidity indicators; • Reports and graphs that describe risk positions; • Concentration indicators of funding providers and time. The document that details the liquidity risk control institutional policy is on the Investor Relations website https://www.itau.com.br/investor-relations, section “Itaú Unibanco”, under “Corporate Governance”, “Rules and Policies, Reports”. 20 Itaú Unibanco

Risk and Capital Management – Pillar 3 Credit Risk CRA: Qualitative information on credit risk management Itaú Unibanco defines credit risk as the risk of loss associated with: failure by a borrower, issuer or counterparty to fulfill their respective financial obligations as defined in the contracts; value loss of credit agreements resulting from deterioration of the borrower’s, issuer’s or counterparty’s credit rating; reduction of profits or income; benefits granted upon subsequent renegotiations; or debt recovery costs. The management of credit risk is intended to preserve the quality of the loan portfolio at levels compatible with the institution’s risk appetite for each market segment in which Itaú Unibanco operates. The governance of credit risk is managed through corporate bodies, which report to the Board of Directors or to the Itaú Unibanco executive structure. Such corporate bodies act primarily by assessing the competitive market conditions, setting the credit limits for the institution, reviewing control practices and policies, and approving these actions at the respective authority levels. The risk communication and reporting process, including disclosure of institutional and supplementary policies on credit risk management, are also function of this structure. Itaú Unibanco manages the credit risk to which it is exposed during the entire credit cycle, from before approval, during the monitoring process and up to the collection or recovery phase. There is a credit risk management and control structure, centralized and independent of the business units which defines operational limits, risk mitigation mechanisms and processes, and instruments to measure, monitor and control the credit risk inherent to all products, portfolio concentrations and impacts to potential changes in the economic environment. Such structure is subjected to internal and external auditing processes. The credit’s portfolio, policies and strategies are continuously monitored so as to ensure compliance with the rules and laws in effect in each country. The key assignments of the business units are (i) monitoring of the portfolios under their responsibility, (ii) granting of credit, taking into account current approval levels, market conditions, the macroeconomic prospects and changes in markets and products, and (iii) credit risk management aimed at making the business sustainable. Itaú Unibanco’s credit policy is based on internal factors, such as: client rating criteria, performance and evolution of the portfolio, default levels, return rates and allocated economic capital, among others; and also take into account external factors such as: interest rates, market default indicators, inflation and changes in consumption, among others. With respect to individuals, small and medium companies, credit ratings are assigned based on statistical application (in the early stages of relationship with a customer) and behavior score (used for customers with whom Itaú Unibanco already has a relationship) models. For large companies, classification is based on information such as the counterparty’s economic and financial situation, its cash-generating capacity, and the business group to which it belongs, the current and prospective situation of the economic sector in which it operates. Credit proposals are analyzed on a case-by-case basis through the approval governance. The concentrations are monitored continuously for economic sectors and largest debtors, allowing preventive measures to be taken to avoid the violation of the established limits. Itaú Unibanco also strictly controls credit exposure to clients and counterparties, acting to reverse occasional limit breaches. In this sense, contractual covenants may be used, such as the right to demand early payment or require additional collateral. To measure credit risk, Itaú Unibanco takes into account the probability of default by the borrower, issuer or counterparty, the estimated amount of exposure in the event of default, past losses from default and concentration of borrowers. Quantifying these risk components is part of the lending process, portfolio management and definition of limits. The models used by Itaú Unibanco are independently validated, to ensure that the databases used in constructing the models are complete and accurate, and that the method of estimating parameters is adequate. Itaú Unibanco counts on a specific structure and processes aimed at ensuring that the country risk is managed and controlled, described in item “Other Risks”. 23 Itaú Unibanco

Risk and Capital Management – Pillar 3 CRC: Qualitative disclosure related to Credit Risk Mitigation techniques Itaú Unibanco uses guarantees to increase its recovery capacity in operations subject to credit risk. The guarantees used can be personal, real, legal structures with mitigating power and offsetting agreements. For guarantees to be considered as credit risk mitigating instruments, they must comply with the requirements and rules that regulate them, whether internal or external, and they must be legally exercisable (effective), enforceable and regularly evaluated. For real guarantees, legal structures with mitigating power and offsetting agreements, the mitigation is based on methodologies established and approved by the business units responsible for the management of credit risk and the centralized area of credit risk control. Such methodologies consider factors related to the legal enforceability of guarantees, the necessary costs and the expected value in the execution, taking into account the volatility and liquidity of the market. Additionally, the concentration of these instruments in the loan portfolio is regularly monitored. Itaú Unibanco also uses credit derivatives to mitigate the credit risk of its securities portfolios. These instruments are priced based on models that use the fair price of market variables, such as credit spreads, recovery rates, correlations and interest rates. The information related to the possible concentration associated with credit risk mitigation considers different mitigating instruments, segregating by type and by provider. For reasons of confidentiality, the institution determines the non-disclosure of information beyond the classification of the type of guarantor, but ensuring adherence to general requirements. Regarding to real guarantees, it is segregated by type: • Financial collaterals • Bilateral contracts • Assets Regarding to personal guarantees, it is segregated by provider: • Legal entities (Public and private companies) • Multilateral Development Entities (EMD) • Financial Institution • Sovereigns • National Treasury or Central Bank Regarding derivatives, it is segregated by provider: • Legal entities • Multilateral Development Entities (EMD) • Financial Institution • Sovereigns CR3: Credit Risk mitigation techniques – overview (1) R$ million 12/31/2020 Exposures Exposures Exposures Unsecured Secured secured by secured by secured by Exposures Exposures financial collateral credit derivatives guarantees Loans 600,583 74,089 6,360 67,729 - Debt securities 391,736 490 490 — - Off-balance sheet exposures 120,349 4,039 670 3,369 - Other Exposures 349,927 4,888 4,888 — - Total 1,462,595 83,506 12,408 71,098 - Of which defaulted 4,610 133 — 133 - (1) The mitigating instruments contemplated in this table are those foreseen in BACEN Circular 3,809. 27 Itaú Unibanco

Risk and Capital Management – Pillar 3 Counterparty Credit Risk (CCR) CCRA: Qualitative disclosure related to CCR Counterparty credit risk is the possibility of noncompliance with obligations related to the settlement of transactions that involve the trading of financial assets with a bilateral risk. It encompasses derivative financial instruments, settlement pending transactions, securities lending and repurchase transactions. Itaú Unibanco has well-defined rules for calculating its exposure to this risk, and the models designed are used both for controlling the use of counterparty limits and for allocating capital. For derivatives, Itaú Unibanco also uses the potential credit risk (PCR), interpreted as the value of the potential financial exposure that a transaction can attain upon maturity. The risk may be mitigated by the use of margin call, initial margin or other mitigating instrument. Currently, Itaú Unibanco does not have impact in the amount of collateral that the bank would be required to provide given a credit rating downgrade. The counterparty credit risk exposures are presented as follows.

Risk and Capital Management – Pillar 3 Securitization Exposures SECA: Qualitative disclosure requirements related to securitisation exposures Currently, Itaú Unibanco occasionally coordinates the issuance of securities in the capital market aiming the securitization of its own assets. In 2020, there were operations in which credits that were accounted for in the balance sheet were totally or partially securitized. In these cases, credits from conglomerate clients were acquired and were subsequently securitized to institutional investors with an appetite for doing so. Itaú Unibanco does not act as a sponsoring counterpart of any specific purpose company with the objective of operating in the securitization market, nor does it manage entities that acquire securities issued or originated by their own. In relation to accounting, it should be noted that (i) assets representing third-party securitizations are accounted for as well as other assets owned by the Bank, according to the brazilian accounting standards; and (ii) securitization credits originating from Itaú Unibanco’s own portfolio remain accounted for in cases of credit assignment with co-obligation. In the first semester of 2020, credit assets were sold in the amount of R$ 1 billion, without substantial retained risks, to a Receivables Investment Fund. In the past 12 months, Itaú Unibanco did not assign exposures with substantial risk retention, which have been honored, repurchased or written-off as losses.

Price Indexes are also treated as a risk factor group. The institutional policy for market risk is in compliance with Resolution 4,557 and establishes the management structure and market risk control, which has the function of: • Provide visibility and comfort for all senior management levels that market risks assumed must be in line with Itaú Unibanco risk-return objectives; • Provide a disciplined and well informed dialogue on the overall market risk profile and its evolution over time; • Increase transparency as to how the business works to optimize results; • Provide early warning mechanisms to facilitate effective risk management, without obstructing the business objectives; and • Monitoring and avoiding the concentration of risks. Market risk is controlled by an area independent of the business units, which is responsible for the daily activities: (i) measuring and assessing risk, (ii) monitoring stress scenarios, limits and alerts, (iii) applying, analyzing and stress testing scenarios, (iv) reporting risk to the individuals responsible in the business units, in compliance with Itaú Unibanco´s governance, (v) monitoring the measures needed to adjust positions and/or risk levels to make them viable, and (vi) supporting the secure launch of new financial products. The market risk management framework categorizes transactions as part of either the Trading Book or the Baking Book, in accordance with general criteria established by CMN Resolution 4,557 and BACEN Circular 3,354. Trading Book is composed of all trades with financial and commodity instruments (including derivatives) undertaken with the intention of trading. Banking Book is predominantly characterized by portfolios originated from the banking business and operations related to balance sheet management, are intended to be either held to maturity, or sold in the medium and in the long term. The market risk management is based on the following key metrics: • Value at Risk (VaR): a statistical metric that quantifies the maximum potential economic loss expected in normal market conditions, considering a defined holding period and confidence interval; • Losses in Stress Scenarios (Stress Testing): a simulation technique to evaluate the impact, in the assets, liabilities and derivatives of the portfolio, of various risk factors in extreme market situations (based on prospective and historic scenarios); 32 Itaú Unibanco

Risk and Capital Management – Pillar 3 • Stop Loss: metrics that trigger a management review of positions, if the accumulated losses in a given period reach specified levels; • Concentration: cumulative exposure of certain financial instrument or risk factor calculated at market value (“MtM—Mark to Market”); and • Stressed VaR: statistical metric derived from VaR calculation, aimed at capturing the biggest risk in simulations of the current trading portfolio, taking into consideration the observable returns in historical scenarios of extreme volatility. In addition to the risk metrics described above, sensitivity and loss control measures are also analyzed. They include: • Gap Analysis: accumulated exposure of the cash flows by risk factor, which are marked-to-market and positioned by settlement dates; • Sensitivity (DV01 – Delta Variation Risk): impact on the market value of cash flows when a 1 basis point change is applied to current interest rates or on the index rates; and • Sensitivities to Various Risk Factors (Greeks): partial derivatives of a portfolio of options on the prices of the underlying assets, implied volatilities, interest rates and time. In an attempt to fit the transactions into the defined limits, Itaú Unibanco hedges its client transactions and proprietary positions, including investments overseas. Derivatives are the most commonly used instruments for carrying out these hedging activities, and can be characterized as either accounting or economic hedge, both of which are governed by institutional regulations at Itaú Unibanco. The structure of limits and alerts is in alignment with the board of directors’ guidelines, being reviewed and approved on an annual basis. This structure extends to specific limits and is aimed at improving the process of risk monitoring and understanding as well as preventing risk concentration. Limits and alerts are calibrated based on projections of future balance sheets, stockholders’ equity, liquidity, complexity and market volatility, as well as the Itaú Unibanco’s risk appetite. 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 uses proprietary systems to measure the consolidated market risk. The processing of these systems takes place in an access-controlled environment, being highly available, which has data safekeeping and recovery processes, and counts on an infrastructure to ensure the continuity of business in contingency (disaster recovery) situations.

These models are applied to operations in the Trading Book and Banking Book. For the Trading Book, the risk factors considered are: interest rates, inflation rates, exchange rates, stocks and commodities. For the Banking Book, exchange rates and commodities are considered.

This methodology uses the returns observed in the past to calculate the gains and losses of a portfolio over time, with a 99% confidence interval and a holding period of at least 10 days. On 12/31/2020, VaR represented 45% of the capital requirement, while the stressed VaR represented 55%. The same methodology 34 Itaú Unibanco

Risk and Capital Management – Pillar 3 is used for management purposes, that is, there are no differences between the managerial and regulatory models. In relation to the VaR model, the historical returns are daily updated. Itaú Unibanco uses in its VaR model both the unweighted approach, in which historical data have the same weight, and the weighted by the volatility of returns. For the calculation of volatilities, the Exponentially Weighted Moving Average method is used. The Historical VaR methodology with 10-day maintenance periods assumes that the expected distribution for possible losses and gains for the portfolio can be estimated from the historical behavior of the returns of the market risk factors to which this portfolio is exposed. The returns observed in the past are applied to current operations, generating a distribution of probability of losses and simulated gains that are used to estimate the Historical VaR, according to the 99% confidence level and using a historical period of 1,000 days. Losses and gains from linear operations are calculated by multiplying mark-to-market by returns, while non-linear operations are recalculated using historical returns. The returns used in simulating the movements of risk factors are relative. Regarding the Stressed VaR model, the calculation is performed for a time horizon of 10 working days, considering the 99% confidence level and simple returns in the historical period of one year. The historical stress period is periodically calculated for the period since 2004 and can be revised whenever deemed necessary. This can occur when the composition of Itaú Unibanco’s portfolios changes significantly, when changes are observed in the results of the simulation of historical returns or when a new market crisis occurs. Losses and gains from linear operations are calculated by multiplying mark to market by returns, while nonlinear operations are recalculated using historical returns. In addition to the use of VaR, Itaú Unibanco carries out daily risk analysis in extreme scenarios through a diversified framework of stress tests, in order to capture potential significant losses in extreme market situations. The scenarios are based on historical, prospective crises and predetermined shocks in risk factors. One factor that has a great influence on the results of the tests, for example, is the correlation between the assets and the respective risk factors, and this effect is simulated in several ways in the various scenarios tested. In order to identify its greatest risks and assist in the decision-making of treasury and senior management, the results of stress tests are assessed by risk factors, as well as on a consolidated basis. The effectiveness of the VaR model is proven by backtesting techniques, by comparing hypothetical and actual daily losses and gains, with the estimated daily VaR, according to BACEN Circular 3,646. The number of exceptions to the established VaR limits must be compatible, within an acceptable statistical margin, with three different confidence intervals (99%, 97.5% and 95%), in three different historical windows (250, 500 and 750 working days). This includes nine different samples, therefore ensuring the statistical quality of the historical VaR hypothesis. Itaú Unibanco has a set of processes, which are periodically executed by the internal control teams, whose objective is to independently replicate the metrics that influence market risk capital by internal models. In addition to the results of the periodic processes, Itaú Unibanco assesses the process of measuring time horizons by risk factors and the estimate of the stress period for calculating the stressed VaR. The validation of the internal model includes several topics considered essential for the critical analysis of the model, such as, the evaluation of the model’s limitations, the adequacy of the parameters used in the volatility estimate and the comprehensiveness and reliability of the input data.

MR4: Comparison of VaR estimates with gains/losses Backtesting The effectiveness of the VaR model is validated by backtesting techniques, comparing daily hypothetical and actual results with the estimated daily VaR. The daily VaR is calculated over a one-day maintenance horizon, according to the 99% confidence level and using a historical period of 1,000 days. The percentage of capital requirement associated with this model is 100%. The backtesting analysis presented below considers the ranges suggested by the Basel Committee on Banking Supervision (BCBS). The ranges are divided into: • Green (0 to 4 exceptions): backtesting results that do not suggest any problem with the quality or accuracy of the adopted models; • Yellow (5 to 9 exceptions): intermediate range group, which indicates an early warning monitoring and may indicate the need to review the model; and • Red (10 or more exceptions): need for improvement actions. The following chart shows the comparison between VaR and actual and hypothetical results. 36 Itaú Unibanco

Risk and Capital Management – Pillar 3 [Graphic Appears Here] The Backtesting presented two exceptions in relation to the hypothetical results and two exceptions in relation to the actual results in the period. This number of exceptions falls within the green range. The exceptions in relation to the hypothetical result occurred on 03/09/2020 and 03/11/2020, in the amounts of R$ 48.5 million and R$ 4.5 million, respectively. These excesses were caused by the increased level of market volatility due to the COVID-19 pandemic. Regarding the actual result, the exceptions occurred on 03/09/2020 and 03/12/2020, in the amounts of R$ 68.3 million and R$ 32.7 million, respectively. These excesses were caused by the increased level of market volatility due to the COVID-19 pandemic. The actual results do not include fees, brokerage fees and commissions.

Risk and Capital Management – Pillar 3 IRRBBA: IRRBB risk management objectives and policies BACEN’s (Central Bank of Brazil) Circular 3,876, published in January 2018, states on methodologies and procedures for evaluation of the capital adequacy, held to cover interest rates risk from instruments held in the banking book. For the purposes of this Circular, are defined: • â^†EVE (Delta Economic Value of Equity) is defined as the 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 the same instruments in an interest-rate shocked scenario; • â^†NII (Delta Net Interest Income) is defined as the difference between the result of financial intermediation of instruments subject to IRRBB in a base scenario, and the result of financial intermediation of the same instruments in an interest-rate shocked scenario. The sensibility analysis introduced here are just a static evaluation of the portfolio interest rate exposure, and, therefore, don´t consider the dynamic management of the treasury desk and risk control areas, which hold the responsibility for measures to mitigate risk under an adverse situation, minimizing significant losses. Moreover, it is highlighted, though, the results presented do not translate into accountable or economic results for certain, because this analysis has, only, an interest rate risk disclosure purpose and to demonstrate the principle protection actions, considering the instruments fair value, apart from any accounting practices adopted by Itaú Unibanco. The institution uses an internal model to measure â^†EVE and â^†NII. â^†EVE results do not represent immediate impact in the stockholders’ equity. Meanwhile, â^†NII results indicate potential volatility in the projected interest rates results. In compliance with the circular 3,876, the following demonstrates qualitative and quantitative details of risk management for IRRBB in Itaú Unibanco. Framework and Treatment Interest rate risk in the banking book refers to the potential risk of impact on capital sufficiency and/or on the results of financial intermediation due to adverse movements in interest rates, taking into account the principal flows of instruments held in the banking book. The main point of assets and liabilities management is to maximize the risk-return ratio of positions held in the banking book, taking into account the economic value of these assets/liabilities and the impact on actual and future bank’s results. The interest rate risk managing on transactions held in the banking book occurs within the governance and hierarchy of decision-making bodies and under a limits structure and alerts approved specifically for these purpose, which is sensitive due to different levels and classes of market risk. The management structure of IRRBB has it owns risk policies and controls intended to ensure adherence to the bank’s risk appetite. The IRRBB framework has granular management limits for several other risk metrics and consolidated limits for â^†EVE and â^†NII results, besides the limits associated with stress tests. The asset and liability management unit is responsible for managing timing mismatches between asset and liability flows, and minimizes interest rate risk by through strategies as economic hedge and accounting hedge. All the models associated with IRRBB have a robust independent validation process and are approved by a CTAM (Technical Model Assessment Commission). In addition, all the models and processes are assessed by internal audit. The interest rate risk framework in the banking book uses management measurements that are calculated daily for limit control. The â^†EVE and â^†NII metrics are calculated according to the risk appetite limits and the other risk metrics in terms of management risk limits. In the process of managing interest rate risk of the banking book, transactions subject to automatic options are calculated according to internal market models which split the products, as far as possible, into linear and non- 38 Itaú Unibanco

Risk and Capital Management – Pillar 3 linear payoffs. The linear payoffs are treated similarly to any other instruments without options, and for nonlinear payoffs an additional value is computed and added on the â^†EVE and â^†NII metrics. In general terms, transactions subject to behavioral options are classified as deposits with no contractual maturity date defined or products subject to early repayment. Non-maturity deposits are classified according to their nature and stability to guarantee compliance with regulatory limits. A survival analysis model treats the products subject to pre-payment, using the historical dataset to calibrate its parameters. The instruments flows with homogeneous characteristics are adjusted by specific models to reflect, in the most appropriate way, the repricing flows of the instruments. The banking book consists of asset and liability transactions originating in different commercial channels (retail and wholesale) of Itaú Unibanco. The market risk exposures inherent in the banking book consists of various risk factors, which are primary components of the market in price formation. IRRBB also includes hedging transactions intended to minimize risks deriving from strong fluctuations of market risk factors and their accounting asymmetries. Market risk generated from structural mismatches is managed by a variety of financial instruments, such as exchange-traded and over-the-counter derivatives. In some cases, operations using derivative financial instruments can be classified as accounting hedges, depending on their risk and cash flow characteristics. In these cases, the supporting documentation is analyzed to enable the effectiveness of the hedge and other changes in the accounting process to be continuously monitored. The accounting and administrative procedures for hedging are defined in BACEN Circular 3,082. The IRRBB model includes a series of premises: • â^†EVE and â^†NII are measured on the basis of the cash flows of the banking book instruments, broken down into their risk factors to isolate the effect of the interest rate and the spread components; • For non-maturity deposits, the models are classified according to their nature and stability and distributed over time considering the regulatory limits; • The institution uses survival analysis models to handle credit transactions subject to prepayment, and empirical models for transactions subject to early redemption; • The medium-term repricing attributed to non-maturity deposits is defined as 1.23 years; • The maximum-term repricing attributed to non-maturity deposits is defined as 32.08 years. The article 39 of the circular defines the need to publish â^†EVE and â^†NII, using the standard shock scenarios described in article 11. Itaú Unibanco has opted to an additional disclosure of the metrics above, considering the internal scenarios, because of the understanding that the standard approach shocks and is application are too conservative. The institution understands that is owns internal scenarios, defined by statistical methodologies, which consider the interest rate historical distribution behavior represent in a more appropriate way the potential risk embedded in the interest rates volatility. Additionally, internal model is more adherent with the way Itaú Unibanco manages its own risks. The table below are presented the main results due the change in the interest rates over the banking book in the standardized scenarios, and, also, in the internal scenarios. It is important to note that, following the normative rules, the potential losses are represented by positive values and potential gains by negative values (between parentheses). • Parallel Up: increasing in the short-term and in the long-term interest rates; • Parallel Down: decreasing in the short-term and in the long-term interest rates; • Short-term increase: increasing in the short-term interest rates; • Short-term reduction: decreasing in the short-term interest rates; • Steepener: decreasing in the short-term interest rates and increasing the in the long-term interest rates; 39 Itaú Unibanco

For the outlier test, the maximum variation of the â^†EVE, with standardized shocks was R$ 7,434 million as of December 31, 2020, corresponding to a potential loss of 5.42% of Tier I, which is less than 15%—percentage that defines the institution as outlier (according to Art. 44 of Circular 3,876). The â^†NII, with internal shocks, for a horizon of a year, has maximum loss of R$ 986 million in the Parallel Down Scenario. Remuneration of Directors The disclosures related to the Remuneration of Directors will be later published, within the period stipulated by Circular 3,930 and subsequent amendments and will be available at www.itau.com.br/investor-relations, section “Reports”, “Pillar 3 and Global Systemically Important Banks”. Other Risks Insurance products, pension plans and premium bonds risks Products that compose portfolios of insurance companies of Itaú Unibanco are related to life and elementary insurance, as well as pension plans and premium bonds. The main risks inherent in these products are described below and their definitions are given in their respective chapters. • Underwriting Risk: possibility of losses arising from insurance products, pension plans and premium bonds that go against institution’s expectations, directly or indirectly associated with technical and actuarial bases used for calculating premiums, contributions and technical provisions; • Market Risk; • Credit Risk; • Operational risk; • Liquidity risk. In line with domestic and international best practices, Itaú Unibanco has a risk management structure which ensures that risks resulting from insurance, pension and special savings products are properly assessed and reported to the relevant forums. The process of risk management for insurance, pensions and premium bond plans is independent and focus on the special nature of each risk. 40 Itaú Unibanco

Risk and Capital Management – Pillar 3 The aim of Itaú Unibanco is to ensure that assets serving as collateral for long-term products, with guaranteed minimum returns, are managed according to the characteristics of the liabilities, so that they are actuarially balanced and solvent over the long term. Social and Environmental Risk Itaú Unibanco understands social and environmental risk as the risk of potential losses due to exposure to social and environmental events arising from the performance of its activities, according to CMN Resolution 4,327/14. The Social and Environmental Responsibility and Sustainability Policy (PRSA) establishes the guidelines, strategies and main principles for social and environmental management, starting from institutional issues, and addressing, through specific procedures, the most relevant risks to the institution’s operation. Mitigation actions on social and environmental risk are carried out through the mapping of processes, risks and controls, the monitoring of new regulations on the subject, and the listing of occurrences in internal databases. In addition to identification, the stages of prioritization, risk response, monitoring and reporting of the assessed risks complement the management of this risk at Itaú Unibanco. The management of this risk is carried out by the first line of defense, business areas that manage it in their daily activities, following the PRSA guidelines, manuals and specific procedures supplemented by the specialized assessment of the dedicated teams of Corporate Compliance, Modeling and Credit Risk and Legal and Institutional department, which work integrated in the management of all the dimensions of Social and Environmental Risk linked to the conglomerate activities. Business units also have the governance for the approval of new products and services, which includes the social and environmental risk assessment, that ensures the compliance in the new products and processes employed by the institution, as well as with specific social and environmental processes applicable to the institution’s own operation (equity, branch infrastructure and technology), suppliers, credit, investments and key subsidiaries. The second line of defense, in turn, is represented by Modeling and Credit Risk, Internal Controls, as well as Compliance, through the Social and Environmental Risk Management, which supports and ensures the governance of the activities of the first line. The third line of defense, composed of Internal Audit, acts independently, carrying out the mapping and assessment of the risk’s management, controls and governance. The Social and Environmental Risk Governance also includes the Social and Environmental Risk Committee, which is primarily responsible for debating and deciding on institutional and strategic issues, as well as deciding on products, operations, services, among others, that involve Social and Environmental Risk, including Climate Risk. Itaú Unibanco constantly seeks to evolve in the management of social and environmental risk, always attentive to the challenges demands of society. Therefore, among other actions, Itaú Unibanco has assumed and incorporated into Itaú Unibanco’s internal processes a number of national and international voluntary commitments and pacts aimed at integrating social, environmental and governance aspects into Itaú Unibanco business. The main ones are the Principles for Responsible Investment (PRI), the Charter for Human Rights – Ethos, the Equator Principles (EP), the Global Pact, the Carbon Disclosure Project (CDP), the Brazilian GHG Protocol Program, the Pacto Nacional para Erradicação do Trabalho Escravo (National Pact for Eradicating Slave Labor), the Task Force on Climate-Related Financial Disclosures (TCFD), among others. Itaú Unibanco efforts to increase the knowledge of the assessment of the social and environmental criteria have been recognized as models in Brazil and abroad, as shown by the recurring presence of the institution in the major sustainability indexes abroad, such as the Dow Jones Sustainability Index, and recently, in Sustainability Index Euronext Vigeo – Emerging 70, and in Brazil, for example in the Corporate Sustainability Index, as well as the numerous prizes which Itaú Unibanco has been awarded. Model Risk The model risk arises from the incorrect development or maintenance of models, such as mistaken assumptions, and inappropriate use or application of the model. 41 Itaú Unibanco

Risk and Capital Management – Pillar 3 The use of models can lead to decisions that are more accurate and therefore it is a major practice in the institution. The models have supported strategic decisions in several contexts, such as credit approval, pricing, volatility curve estimation, calculation of capital, among others. Due to the increasing use of models, driven by the application of new technologies and the expansion of data use, Itaú Unibanco has improved its governance in relation to its development and monitoring, through the definition of guidelines, policies and procedures aimed at assuring the quality and mitigation of the associated risks. Regulatory or Compliance Risk Regulatory or Compliance risk is the risk associated with any nature, financial losses or damage to reputation, arising from non-compliance with external or internal standards, commitments to regulators, codes of self-regulation, methods or codes of conduct related to the activities of the Conglomerate. This risk is managed through a structured process aimed at identifying changes in the regulatory environment, analyzing their impacts on the departments of the institution and monitoring the actions directed at adherence to the regulatory requirements and codes of ethics. This structured process includes the following actions: (i) to understand the changes in the regulatory environment; (ii) to monitor regulatory trends; (iii) to care for the relationship between the institution and the regulator, self-regulatory bodies and the representation entity; (iv) to monitor action plans on regulatory or self-regulatory compliance; (v) to coordinate a program to comply with significant norms, such as Integrity and Ethics; and (vi) to report regulatory issues in Operational and Compliance Risk forums, according to the structure of committees established in internal policies. Reputational Risk Itaú Unibanco understands reputational risk as the risk arising from internal practices and/or external factors that may generate a negative perception of Itaú Unibanco by customers, employees, shareholders, investors, regulatory bodies, government, suppliers, the press and the society in general. It can impact the bank’s reputation, the value of its brand and/or result in financial losses. Besides, this can affect the maintenance of existing business relationships, access to sources of fundraising, the attraction of new business and talent to compose the company’s staff or even the license to operate. The institution believes that its reputation is extremely important for achieving its long-term goals, which is why it seeks the alignment of the speech, the action and the ethical and transparent practice, essential to raise the confidence of Itaú Unibanco’s stakeholders. Itaú Unibanco’s reputation depends on its strategy (vision, culture and skills) and derives from direct or indirect experience of the relationship between Itaú Unibanco and its stakeholders. Since the reputational risk directly or indirectly permeates all operations and processes of the institution, Itaú Unibanco’s governance is structured in a way to ensure that potential risks are identified, analyzed and managed still in the initial phases of its operations and analysis of new products, including the use of new technologies. The treatment given to reputational risk is structured by means of many processes and internal initiatives, which, in turn, are supported by internal policies, and their main purpose is to provide mechanisms for the monitoring, management, control and mitigation of the main reputational risks. Among them are (i) risk appetite statement; (ii) process for the prevention and fight against unlawful acts; (iii) crisis management process and business continuity; (iv) processes and guidelines of the governmental and institutional relations; (v) corporate communication process; (vi) brand management process; (vii) ombudsman offices initiatives and commitment to customer satisfaction; and (vii) ethics guidelines and prevention of corruption. Financial institutions play a key role in preventing and fighting illegal acts, in particular money laundering, terrorist financing and fraud, in which the challenge is to identify and suppress increasingly sophisticated operations that seek to conceal the origin, location, disposition, ownership and movement of goods and money derived, directly or indirectly, from illegal activities. Itaú Unibanco has introduced a corporate policy in order to prevent its involvement in illegal acts and to protect its reputation and image towards employees, clients, 42 Itaú Unibanco

Risk and Capital Management – Pillar 3 strategic partners, suppliers, service providers, regulators and society, through a governance structure based on transparency, strict compliance with rules and regulations, including BACEN Circular 3,978/20 among others, and cooperation with police and judicial authorities. It also seeks a continuously alignment with local and international best practices for preventing and fighting against illegal acts, through investing and training eligible employees. In compliance with the guidelines of this corporate policy, Itaú Unibanco established a program to prevent and fight against illegal acts based on the following pillars: • Policies and Procedures • Client Identification Process; • Know Your Customer (KYC) Process; • Know Your Partner (KYP) Process; • Know Your Supplier (KYS) Process; • Know Your Employee (KYE) Process; • Assessment of New Products and Services; • Compliance with Sanctions • Monitoring, Selection and Analysis of Suspicious Operations or Situations ; • Reporting Suspicious Transactions to the Regulatory Bodies; and • Training. This program applies to the entire institution, including subsidiaries and affiliates in Brazil and abroad. The preventing and combating unlawful acts governance is carried out by the Board of Directors, Audit Committee, Operational Risk Committee, Risk and Capital Management Commitee and Anti-Money Laundering Committees. The document that presents the guidelines established in the corporate program to prevent and combat unlawful acts may be seen on the www.itau.com.br/investor-relations, section Itaú Unibanco, under Corporate Governance, Rules and Policies, Policies, Corporate Policy for Prevention and Fight Against Illegal Acts. In addition, Itaú Unibanco has been developing various data analysis models to improve customer risk classification, transaction monitoring and KYC methodology to provide greater accuracy in its analysis and to decrease false-positives. Itaú Unibanco has also been innovating its modeling solutions using new methods based on machine learning techniques to identify potentially suspicious activities. Moreover, Itaú Unibanco is committed to protecting corporate information and ensuring client and general public privacy in any transactions. To this end, it has a Corporate Information Security Policy and Cyber Secutity and has a monitoring process and a control structure that covers technology, business areas and international units, adhering to principal regulatory bodies and external audits, and best market practices and certifications. Additionally, a Security Operation Center (SOC) that works 24/7 contributes to the cyber security of Itaú Unibanco’s electronic channels and IT infrastructure, to the monitoring of operations and thus the minimization of the risk of a security incident. The Corporate Information Security and Cyber Security Policy can be viewed on the website www.itau.com.br/investor-relations, section Itaú Unibanco, under Corporate Governance, Rules and Policies, Policies, Corporate Policy on Information Security and Cyber Security. Country Risk The country risk is the risk of losses related to non-compliance with obligations in connection with borrowers, issuers, counterparties or guarantors, as a result of political-economic and social events or actions taken by the government of the country. Itaú Unibanco has a specific structure for the management and control of country risk, consisting of corporate bodies and dedicated teams, with responsibilities defined in policies. The institution has a structured and consistent procedure, including: (i) establishment of country ratings; (ii) determination of limits for countries; (iii) monitoring the use of limits. 43 Itaú Unibanco

Risk and Capital Management – Pillar 3 Business and Strategy Risk Business and strategy risk is the risk of a negative impact on the results or capital as a consequence of a faulty strategic planning, the making of adverse strategic decisions, the inability of Itaú Unibanco to implement the proper strategic plans and/or changes in its business environment. Itaú Unibanco has implemented many mechanisms that ensure that both the business and the strategic decision-making processes follow proper governance standards, have the active participation of executives and the Board of Directors, are based on market, macroeconomic and risk information and are aimed at optimizing the risk-return ratio. Decision-making and the definition of business and strategy guidelines, count on the full engagement of the Board of Directors, primarily through the Strategy Committee, and of the executives, through the Executive Committee. In order to handle risk adequately, Itaú Unibanco has governance and processes to involve the ARF in business and strategy decisions, so as to ensure that risk is managed and decisions are sustainable in the long term. They are: (i) qualifications and incentives of board members and executives; (ii) budget process; (iii) product assessment; (iv) evaluation and prospecting of proprietary mergers and acquisitions; and (v) a risk appetite framework which, for example, restricts the concentration of credit and exposure to specific and material risks. Contagion Risk Contagion Risk is the possibility of losses occurring for entities that are part of the Prudential Conglomerate as a result of financial support to unconsolidated entities, in a stressful situation, in the absence or in addition to the obligations provided for in the contract. Itaú Unibanco has a structure for risk management and control, a dedicated team and a policy that defines roles and responsibilities. This structure covers (i) the identification of entities in relation to the potential generation of contagion risk, (ii) the assessment of risks in relationships, (iii) the monitoring, control and mitigation of contagion risk, (iv) the assessment of impact on capital and liquidity and (v) reports. It is part of the scope of contagion risk governance: Related Party audiences, mainly composed of controllers, controlled and related entities (as defined in Res. 4,693 / 18), investments in non-consolidated entities, suppliers of critical products and services, buyers and sellers of relevant assets, third parties with products distributed by Itaú Unibanco and third parties to whom Itaú Unibanco distributes products. Operational Risk Operational risk is defined as the possibility of losses arising from failure, deficiency or inadequacy of internal process, people or systems or from external events that affect the achievement of strategic, tactical or operational objectives. It includes legal risk associated with inadequacy or deficiency in contracts signed by the institution, as well as penalties due to noncompliance with laws and punitive damages to third parties arising from the activities undertaken by the institution. Itaú Unibanco internally classifies its risk events in: • Internal fraud; • External fraud; • Labor claims and deficient security in the workplace; • Inadequate practices related to clients, products and services; • Damages to own physical assets or assets in use by Itaú Unibanco; • Interruption of Itaú Unibanco’s activities; • Failures in information technology (IT) systems, processes or infrastructure; • Failures in the performance, compliance with deadlines and management of activities at Itaú Unibanco. Operational risk management includes conduct risk, which is subject to mitigating procedures to assess product design (suitability) and incentive models. The inspection area is responsible for fraud prevention. Irrespective of their origin, specific cases may be handled by risk committees and integrity and ethics committees. Itaú Unibanco has a governance process that is structured through forums and corporate bodies composed of senior management, which report to the Board of Directors, with well-defined roles and responsibilities in order to segregate the business and management and control activities, ensuring independence between the areas and, 44 Itaú Unibanco

Risk and Capital Management – Pillar 3 consequently, well-balanced decisions with respect to risks. This is reflected in the risk management process carried out on a decentralized basis under the responsibility of the business areas and by a centralized control carried out by the internal control, compliance and operational risk department, by means of methodologies, training courses, certification and monitoring of the control environment in an independent way. The managers of the executive areas use corporate methods constructed and made available by the internal control, compliance and operational risk area. Among the methodologies and tools used are the self-evaluation and the map of the institution’s prioritized risks, the approval of processes, products, and system development products and projects, the monitoring of key risk indicators that and the database of operational losses, guaranteeing a single conceptual basis for managing processes, systems, projects and new products and services. Within the governance of the risk management process, regularly, the consolidated reports on risk monitoring, controls, action plans and operational losses are presented to the business area executives. In line with CMN Resolution 4,557, the document “Public Access Report—Integrated Operational Risk Management and Internal Controls”, summarized version of the institutional operational risk management policy can be found on the website www.itau.com.br/investor-relations, section Itaú Unibanco, under Corporate Governance, Rules and Policies, Reports. Crisis Management and Business Continuity Itaú Unibanco’s Business Continuity Program’s purpose is to protect its employees, ensure the continuity of the critical functions of its business lines and sustain both the stability of the markets in which it operates and the confidence of its customers and strategic partners in its provision of services and products . It establishes the Business Continuity Plan (BCP), which consists of modular procedures that are available for use in the event of incidents. The descriptions/characteristics of the existing plans are: • Disaster Recovery: it aims to ensure the availability and integrity of Information Technology resources and communication in the event of a failure in the primary Data Center to maintain the processing of critical systems; • Workplace Contingency: alternative facilities to perform the activities in the event the administrative buildings become unavailable; • Operational Contingency: alternatives to carry out critical processes whether they are systemic, procedural or emergency responses. In order to assess the efficiency of the contingency actions in the face of the interruption scenarios described in the plans and identify improvement points, tests are carried out at intervals that vary according to the plan, at least once a year. In order to keep the continuity solutions aligned with the business requirements (processes, minimum resources, legal requirements, etc) the Program applies the following tools to assess the institution: • Business Impact Analysis (BIA): evaluates the criticality and resumption requirement of the processes that support the delivery of products and services. • Threats and Vulnerabilities Analysis (AVA): identification of threats near to Itaú Unibanco’s buildings. Considering the dependence that some processes have on third-party services, the Business Continuity Program conducts an assessment of the risk of unavailability of services provided with a view to resilience to threats of interruption. In addition, the institution has a Crisis Management Program, which is aimed at managing business interruption events, natural disasters, impacts of an environmental, social, and infrastructure/operational (including information technology) or of any other nature that jeopardize the image and reputation and/or viability of Itaú Unibanco’s processes with its employees, clients, strategic partners and regulators, with timely and integrated responses. 45 Itaú Unibanco

Risk and Capital Management – Pillar 3 To assess the efficiency and identify points of improvement in contingency actions and crisis response plans, tests are carried out, which frequency varies according to the plan (at least once a year). Independent Validation of Risk Models Itaú Unibanco validates the processes and risk models independently. This is done by a department which is separate from the business and risk control areas, to ensure that its assessments are independent. The validation method, defined in an internal policy, meets regulatory requirements such as those of BACEN Circulars 3,646 and 3,674. The validation stages include: • Verification of mathematical and theoretical development of the models; • Qualitative and quantitative analysis of the models, including the variables, construction of an independent calculator and the use of appropriate technical; • When applicable, comparison with alternative models and international benchmarks; • Historical Backtesting of the model; • The correct implementation of the models in the systems used. Additionally, the validation area assesses the stress testing program. The performance of the independent validation area and the validation of the processes and models are assessed by Internal Audit and reported to the specific senior management committees. Action plans are prepared to address opportunities identified during the independent validation process, and are monitored by the 3 lines of defense and by senior management until the conclusion. 46 Itaú Unibanco
